We describe a case of metachronous liver metastasis after CRS and HIPEC for colorectal cancer, successfully treated with a selective metastectomy and partial graft of the inferior vena cava. A 35-year-old female presented with a large tumour in the cecum and consequent colonic stenosis. After an emergency right colectomy, the patient received adjuvant chemotherapy. One year later she was diagnosed with peritoneal carcinomatosis, and it was decided to carry out a CRS/HIPEC. After 2 years of total remission, an isolated metachronous liver metastasis was detected by magnetic resonance imaging surveillance. The patient underwent a third procedure including a caudate lobe and partial inferior vena cava resection with a prosthetic graft interposition, achieving an R0 situation. The postoperative course was uneventful and the patient was discharged on postoperative day 17 after the liver resection. At 18-mo follow-up after the liver resection the patient remained free of recurrence. In selected patients, the option of re-operation due to recurrent disease should be discussed. Even liver resection of a metachronous metastasis and an extended vascular resection are acceptable after CRS/HIPEC and can be considered as a potential treatment option to remove all macroscopic lesions.展开更多

The platelet count;vascular activity-related factors v WF, VCAM-1, and TM;and VEGF and b FGF were used as observational indicators.Results: On the 8th day of administration, compared with the model group, platelet counts in the prednisone and JYSD groups increased(both P <.001). Compared with the control group, the levels of v WF, VCAM-1, and TM in the other groups were lower(all P <.05). The VCAM-1 level in the JYSD group was higher than that in the prednisone group(P =.012), but without significant difference compared with the model group(P =.051). The TM level in the JYSD group was the lowest(vs. the model group,P =.047;vs. the prednisone group, P =.006). Compared with the control group, the IOD values of VEGF and b FGF in the other three groups were lower(all P <.01). The IOD values of VEGF in the prednisone and JYSD groups were both higher than those in the model group(P =.002 and P <.001, respectively). The IOD values of b FGF among the model, prednisone, and JYSD groups were not statistically significant(P >.05).Conclusion: A vascular factor disorder is involved in the pathogenesis of ITP. JYSD can increase the platelet count, upregulate VEGF expression, and reduce the TM level. JYSD has the same effect as prednisone tablets in regulating platelet, v WF, VEGF, and b FGF, with a stronger effect in normalizing VCAM-1 and TM levels. The hemostatic mechanism of JYSD is closely related to the effective balance of vascular factors.展开更多

Material and Methods: For 30 patients with BRONJ, gender, age, underlying diagnosis, type of bisphosphonate (BP), administration route and duration, location and stage of osteonecrosis, symptoms and oral health status, radiological findings of the jaws, treatment and outcome, were recorded. Results: Underlying diagnoses in the series (12 male;18 female;mean age 70.50 ± 9.62) were: 12 multiple myeloma, 7 breast cancer, 3 prostate carcinoma, 1 kidney/lung/ bladder/mediastinal cancer, 1 chronic lymphocytic leukemia, 1 osteoporosis, 1 palatal osteosarcoma + osteoporosis, 1 non-Hodgkin’s lymphoma. Forty-seven osteonecrotic lesions were detected;30 localized in the mandible,17 inthe maxilla;trigger events were tooth extraction in 31 cases (66%), periodontal disease in 4 (8.50%), incongruous dentures in 3 (6.40%), perimplantitis in 1 (2.10%), unknown in 8 (17%). Twenty-nine patients had received treatment using amino bisphosphonates (25 zoledronate, 2 pamidronate, 2 alendronate) and 1 clodronate;the administration route was intravenous in 27 patients, oral in 2 and intramuscular in 1. Mean number of doses to bone exposure for patients was 34.11 for zoledronate, 50.50 for pamidronate, 146 for alendronate, and 500 for clodronate. Among statistical data the only significant finding was that panoramic dental radiography gave no concrete support for diagnosis of ONJ lesions (p ≤ 0.04). Conclusions: Our case series reflects literature data. We emphasize the insufficient role of panoramic radiography to study osteonecrotic lesions and the role of poor oral hygiene.展开更多

Darbe (150 micro g total dose/weekly) was initiating in four weeks after AHPCT, with the aim of achieving an Hb level of ≥11 g/dl. The time to response to Darbe therapy was longer in the patients with Hb < 10 g/dL (p = 0.05) and with endogenous Epo levels ≤ 50 mU/ml (p = 0.0098). Hb level on day 60 and 90 after AHPCT, was faster for Darbe recipients (12.5, range 9.4 - 15.4, vs 10.6, range 8.8 - 13.4 g/dL, p = 0.0001, and 13.5, range 12.3 - 14.3, vs 12, range 9.8 - 14 g/dL, respectively, p = 0.0001). The need for Red Blood Cells transfusion, included in the period of 30 - 90 days post- AHPCT was similar (p = ns). This study demonstrates the accelerating effect of Darbe on Hb increase in the setting evaluated and shows that this effect signify- cantly depends on the endogenous Epo level at the start of treatment. The strategy of giving Darbe around 1 month after high-dose melphalan (HDM) doesn’t reduce RBC transfusion requirement.展开更多

Moreover, 34 patients with pure lymphnoditis were served as the control group. FCM and full-automatic speed scattering turbidimetry were used to detect T lymphocyte subsets proportion, IgG, IgA, IgM, C3, and C4 in the three groups.Results: The comparison of CD3+, CD4+, CD8+, NK cell proportion, and CD4+/CD8+ among the three groups was significantly different. When compared with the control group, CD3+, CD4+, CD8+, NK cell proportion, and CD4+/CD8+ in the extranodular group and nodular group were significantly reduced;moreover, CD3+, CD4+, CD8+, and CD4+/CD8+ in the extranodular group were significantly lower than those in the nodular group, while NK cell in the extranodular group was significantly higher than that in the nodular group. The comparison of IgG, IgA, and C3 levels among the three groups was statistically significant. When compared with the control group, IgG and IgA levels in the extranodular group and nodular group were significantly elevated, while C3 level was significantly reduced, and the comparison between the extranodular group and nodular group between the two groups was statistically significant. IgM level in the extranodular group and nodular group was elevated, C4 level was reduced, but the comparison with the control group was not statistically significant. Spearman correlation analysis showed that CD3+ and CD4+ were significantly correlated with IgA, IgG, and C3.Conclusions: With the increasing of severity degree of lymphoma, the immunological level is reduced, while CD3+ and CD4+ are significantly correlated with IgA, IgG, and C3, indicating that detection of CD3+ and CD4+ proportion or IgA, IgG, and C3 contents in combined with pathological characteristics can evaluate the severity degree of malignant lymphoma in order to provide guidance for the clinical diagnosis and treatment.展开更多

文摘Background:Drug resistance is the main factor contributing to cancer recurrence and poor prognosis.Exploration of drug resistance-related mechanisms and effective therapeutic targets are the aim of molecular targeted therapy.In our study,the role of long non-coding RNA(lncRNA)AFAP1-AS1 in gemcitabine resistance and related mechanisms were explored in cervical cancer cells.Methods:Gemcitabine-resistant cervical cancer cell lines HT-3-Gem and SW756-Gem were constructed using the gemcitabine concentration gradient method.The overall survival rates and recurrence-free survival rates were evaluated by Kaplan-Meier analysis.The interaction was verified through a Dual-luciferase reporter gene assay and a Biotinylated RNA pull-down assay.Cell proliferation ability was assessed through methyl-thiazolyl-tetrazolium(MTT),soft agar,and colony formation experiments.Cell cycle and apoptosis were detected byflow cytometry.Results:Up-regulation of AFAP1-AS1 in cervical cancer predicted a poor prognosis.Besides,patients in the gemcitabine-resistance group had higher levels of AFAP1-AS1 than the gemcitabine-sensitive group.AFAP1-AS1 promoted tumor growth and induced gemcitabine tolerance of cervical cancer cells.In addition,AFAP1-AS1 mediated epidermal growth factor receptor(EGFR)expression by serving as a molecular sponge for microRNA-7a-5p(miR-7-5p).This present study also proved that the knockdown of EGFR or overexpression of miR-7a-5p abolished the accelerative role of AFAP1-AS1 overexpression in cancer progression and gemcitabine tolerance.Conclusions:In general,the AFAP1-AS1/miR-7-5p/EGFR axis was tightly related to the progression and gemcitabine tolerance of cervical cancer,providing potential targets for the management of cervical cancer.

文摘Objective:To evaluate the effectiveness and safety of seven oral Chinese patent medicines(CPMs)as adjuvant therapy for cancer-related anemia(CRA)by network meta-analysis(NMA).Methods:A literature search to obtain randomized controlled trials(RCTs)of seven oral CPMs in the adjuvant treatment of CRA was conducted in multiple databases from the inception to April 2022.The RevMan5.3 and R 4.1.1 software were used for NMA.Results:We ultimately included 29 RCTs with 2140 patients.Traditional meta-analysis showed that Fufang E'jiao syrup(FFEJS),Shengxuebao mixture(SXBM),Shengxuening tablets(SXNT),Jianpi Shengxue granules(JPSXG),and Yixuesheng capsule(YXSC)combined with basic Western treatment(BWT)could improve the hemoglobin(HGB)level.JPSXG combined with BWT could improve the red blood cell(RBC).FFEJS combined with BWT improved the Karnofsky performance status(KPS).NMA showed that FFEJS,JPSXG,SXBM,and SXNT plus BWT improved HGB better than Shengxue tablets(SXT)plus BWT,with top three ranking results being JPSXG plus BWT>SXNT plus BWT>FFEJS plus BWT.FFEJS plus BWT,JPSXG plus BWT,SXBM plus BWT,SXNT plus BWT,and SXT plus BWT improved RBC better than BWT,with top three ranking results being SXNT plus BWT>JPSXG plus BWT>FFEJS plus BWT.In terms of the KPS score,compared with SXT plus BWT,FFEJS,JPSXG,SXBM,SXNT,and Yizhong Shengxue capsule(YZSXC)plus BWT had higher KPS,with top three ranking results being SXBM plus BWT>JPSXG plus BWT>FFEJS plus BWT.Conclusions:Our NMA demonstrated that seven oral CPMs used as adjuvant treatment of CRA had a definite clinical effect.JPSXG not only increases the levels of HGB and RBC to enhance the clinical effect but also improves patients'quality of life.More accurate conclusions need to be verified by more high-quality RCTs.
文摘BACKGROUND Chemotherapy for malignant tumors can cause brain changes and cognitive impairment,leading to chemotherapy-induced cognitive impairment(CICI).Current research on CICI has focused on breast cancer and Hodgkin’s lymphoma.Whether patients with non-Hodgkin’s lymphoma(NHL)undergoing chemo-therapy have cognitive impairment has not been fully investigated.therapy have cognitive impairment has not been fully investigated.AIM To investigate whether NHL patients undergoing chemotherapy had cognitive impairments.METHODS The study included 100 NHL patients who were required to complete a compre-hensive psychological scale including the Brief Psychiatric Examination Scale(MMSE)at two time points:before chemotherapy and within 2 wk of two chemo-therapy courses.A language proficiency test(VFT),Symbol Number Pattern Test(SDMT),Clock Drawing Test(CDT),Abbreviated Daily Cognition Scale(ECog-12),Prospective and Retrospective Memory Questionnaire,and Karnofsky Perfor-mance Status were used to assess cognitive changes before and after chemo-therapy.RESULTS The VFT scores for before treatment(BT)and after treatment(AT)groups were 45.20±15.62,and 42.30±17.53,respectively(t-2.16,P<0.05).The CDT scores were 8(3.5-9.25)for BT and 7(2.5-9)for AT groups(Z-2.1,P<0.05).Retrospective memory scores were 13.5(9-17)for BT and 15(13-18)for AT(Z-3.7,P<0.01).The prospective memory scores were 12.63±3.61 for BT and 14.43±4.32 for AT groups(t-4.97,P<0.01).The ECog-12 scores were 1.71(1.25-2.08)for BT and 1.79(1.42-2.08)for AT groups(Z-2.84,P<0.01).The SDMT and MMSE values did not show a significant difference between BT and AT groups.CONCLUSION Compared to the AT group,the BT group showed impaired language,memory,and subjective cognition,but objec-tive cognition and execution were not significantly affected.
文摘There are diverse protocols to manage patients with recurrent disease after primary cytoreductive surgery(CRS) with hyperthermic intraperitoneal chemotherapy(HIPEC) for peritoneal carcinomatosis. We describe a case of metachronous liver metastasis after CRS and HIPEC for colorectal cancer, successfully treated with a selective metastectomy and partial graft of the inferior vena cava. A 35-year-old female presented with a large tumour in the cecum and consequent colonic stenosis. After an emergency right colectomy, the patient received adjuvant chemotherapy. One year later she was diagnosed with peritoneal carcinomatosis, and it was decided to carry out a CRS/HIPEC. After 2 years of total remission, an isolated metachronous liver metastasis was detected by magnetic resonance imaging surveillance. The patient underwent a third procedure including a caudate lobe and partial inferior vena cava resection with a prosthetic graft interposition, achieving an R0 situation. The postoperative course was uneventful and the patient was discharged on postoperative day 17 after the liver resection. At 18-mo follow-up after the liver resection the patient remained free of recurrence. In selected patients, the option of re-operation due to recurrent disease should be discussed. Even liver resection of a metachronous metastasis and an extended vascular resection are acceptable after CRS/HIPEC and can be considered as a potential treatment option to remove all macroscopic lesions.

文摘Objective:To investigate the anti-angiogenic effect of tea polyphenols(TPS)on breast cancer and normal tissues in a mouse model.Methods:Breast cancer was successfully implanted into 48 BALB/c mice,which were then randomly divided into a TP oral gavage group,a TP local injection group,a ginsenoside Rg3 group,and a model control group according to a random number table.The tumor inhibitory rates of each group were calculated,while microvessel density(MVD)and the expression of vascular endothelial growth factor(VEGF),basic fibroblast growth factor(bFGF),and tissue inhibitor of metalloproteinase(TIMP-2)were detected by immunohistochemistry.Results:TPs could inhibit the growth of breast cancer xenografts in the mouse model.The tumor inhibition rates of the TP oral gavage and TP local injection groups were 37.43%and 40.94%,respectively.Compared with the model control group,MVD and VEGF and bFGF expression was downregulated(all P<.05),whereas TIMP-2 expression was elevated in the TP oral gavage and TP local injection groups(P=.015 and P=.032).TPs showed no significant effect on MVD and VEGF and TIMP-2 expression in the heart,brain,and kidney of the mouse model.Conclusion:TPs can restrict the growth of breast cancer by specifically inhibiting the angiogenesis of breast tumor tissue while having little effect on the normal tissue of important organs including the heart,brain,and kidney.
文摘Objective:As prostate cancer(Pr C)shows a BRCA mutation rate as high as 30%,it becomes crucial to find the optimal selection criteria for genetic testing.The primary objective of this study was to evaluate the BRCA mutation rate in families with Pr C associated with breast and/or ovarian cancers;secondary aims were to compare the characteristics of families and BRCA-related Pr C outcome among BRCA1 and BRCA2 carriers.Methods:Following the Modena criteria for the BRCA test,we evaluated the mutation rate in families with breast and/or ovarian cancer with a Gleason score≥7 Pr Cs,by testing breast or ovarian cases and inferring the mutation in the prostate cases.The characteristics of families and BRCA-related Pr C outcomes were measured using the chi-square(χ^(2))test and Kaplan–Meier methods,respectively.Results:Among 6,591 families,580(8.8%)with a Gleason score≥7 Pr Cs were identified,of which 332(57.2%)met the Modena selection criteria for BRCA testing.Overall,215 breast or ovarian cancer probands(64.8%)were tested,of which 41 resulted positive for BRCA and one for CHEK2 genes(19.5%).No statistically significant differences were found in BRCA-related Pr C prognosis and in the characteristics of families among BRCA1,BRCA2 and non-tested patients.Ten of 23(44%)mutations in the BRCA2 gene fell in the prostate cancer cluster region(PCCR)at the 3′terminal of the 7914 codon.Conclusions:It appears the Modena criteria are very useful for BRCA testing selection in families with breast and/or ovarian cancer and Pr C.A trend toward a worse prognosis has been found in BRCA2 carriers.
文摘This consensus statement is organized into six parts:1)Definitions:cancer-related depressed mood state is defined as a group of depressive symptoms,rather than major depressive disorder.Thus,“cancer-related depression”or“depressed mood state”is introduced as standard terminology and associated with the Chinese medicine concept of“yu zheng”(depression syndrome).2)Pathogenesis:factors including psychological stress,cancer pain,cancer fatigue,sleep disorders,surgery trauma,chemotherapy,and radiation therapy are strongly associated with cancer-related depressed mood state.Crucial elements of pathogenesis are cancer caused by depression,depression caused by cancer,and the concurrence of phlegm,dampness,and stasis from constrained liver-qi and spleen deficiency.3)Symptoms:these include core symptoms,psychological symptoms,and somatic symptoms.Depressed mood and loss of interest are the main criteria for diagnosis.4)Clinical evaluation:based on the Mini-International Neuropsychiatric Interview and a numeric rating scale,and taking mood changes during cancer diagnosis and treatment into consideration,a questionnaire can be drafted to distinguish between major depressive disorder and cancer-related depression.The aim is to assist oncology clinicians to identify,treat,and refer patients with cancer-related depression.5)Diagnosis:diagnosis should be based on the Chinese Classification for Mental Disorders(CCMD-3),taking patients’mood changes during diagnosis and treatment into consideration.6)Treatment:treatments for cancer-related depression must be performed concurrently with cancer treatment.For mild depression,non-pharmacologic comprehensive therapies,including psychological intervention,music therapy,patient education,physical activity,and acupuncture,are recommended;for moderate depression,classical Chinese herbal formulas based on syndrome pattern differentiation combined with antidepressants are suggested;for severe depressive symptoms that have progressed to major depressive disorder, patients should be referred to a psychiatric clinician for specialized care.
文摘Objective:Neuraxial anesthesia(NA)showed to reduce both morbidity and mortality in patients undergoing laparoscopic surgery.We aimed to investigate the use of NA in patients undergoing transperitoneal three-dimensional laparoscopic radical prostatectomy(t-3DLRP)and compare the intraoperative and postoperative outcomes with a control group of patients undergoing t-3DLRP under general anesthesia(GA).Methods:A prospective,double-center,double-surgeon study cohort of 84 consecutive patients undergoing t-3DLRP between June 2019 and June 2021 was analyzed.A study group of 42 patients undergoing t-3DLRP under NA was compared with a control group of 42 patients undergoing t-3DLRP under GA.Results:The two group were similar in all demographic,clinical,and pathological variables.Postoperative blood gas parameters were within physiologic limits in both groups.Muscle relaxation was adequate for surgery during both NA and GA.Median length of stay was 1 day shorter for NA group than GA group(5 days vs.6 days,p=0.05).t-3DLRP under NA had a statistically lower rate of minor complications(4.8%vs.19.0%,p=0.03)and less postoperative pain(median numeric rating scale 3 vs.4,p=0.01)compared to GA.No major complications were observed in both groups.Significantly more patients were willing to undergo a similar intervention under NA than GA(p=0.04).Conclusion:t-3DLRP under NA is a feasible and safe procedure,with less postoperative pain and fewer minor complications than the same procedure under GA.NA allows the maintenance of muscle relaxation and respiratory excursions without interfering with surgery.
文摘BACKGROUND In the United States,sorafenib monotherapy was approved in 2007 for first-line(1L)treatment of patients with unresectable hepatocellular carcinoma(uHCC).As other therapies have been approved in recent years for hepatocellular carcinoma treatment in later lines,it is essential to assess clinical effectiveness of older therapies in actual clinical practice to inform healthcare practitioners’decisions for better patient care.AIM To assess patient characteristics/clinical effectiveness of 1L sorafenib in uHCC patients treated in United States academic and community practice settings.METHODS A retrospective observational study was conducted among adult patients(≥18 years)in the United States initiating sorafenib monotherapy as 1L systemic therapy for uHCC with Eastern Cooperative Oncology Group status of 0 or 1 between January 2016 and December 2019 at City of Hope and Advent Health.Data were extracted by trained abstractionists from individual patients’electronic health records and captured in electronic case report forms.Institutional Review Board approvals were obtained prior to study initiation.Data were captured from the time of sorafenib initiation until death or the end of follow-up.All data were de-identified prior to analyses.Clinical outcomes assessed included provider-reported best response,progression-free survival(PFS),and overall survival(OS).PFS and OS were estimated using Kaplan-Meier methods.RESULTS Among 134 uHCC patients treated with 1L sorafenib,majority were male(75%),and most were Caucasian(62%)or Asian(19%).Median patient age was 64 years.The most common etiologies of liver disease were hepatitis C(54%),alcohol-related liver disease(16%),and hepatitis B(11%).Most patients were reported to have Barcelona Clinic Liver Cancer stage B(19%)or stage C(70%)disease.Of 134 patients,110(82%)were reported to have discontinued treatment or died during follow-up.Primary reasons for sorafenib discontinuation were reported as progression(35%)and toxicity(30%).Best overall response was reported for 124 patients,of which 7.3%reported complete or partial response.Median time to treatment discontinuation was 2.3 mo.Overall,103 patients(77%)had disease progression or died during sorafenib therapy.Median PFS was estimated to be 2.9 mo.At the end of follow-up,82 patients(61%)were deceased.Median OS was 8.5 mo.CONCLUSION Newer therapeutic options that have reported higher PFS and OS in real-world clinical practice should be considered to enhance patient outcomes.

文摘Objective: To explore the hemostatic mechanism of Jianpi Yiqi Shexue decoction(JYSD) by regulating vascular factors in an immune thrombocytopenia(ITP) mouse model.Methods: An ITP mouse model was established by the passive-immune modeling method, and interventional drugs used were prednisone tablets and JYSD. The platelet count;vascular activity-related factors v WF, VCAM-1, and TM;and VEGF and b FGF were used as observational indicators.Results: On the 8th day of administration, compared with the model group, platelet counts in the prednisone and JYSD groups increased(both P <.001). Compared with the control group, the levels of v WF, VCAM-1, and TM in the other groups were lower(all P <.05). The VCAM-1 level in the JYSD group was higher than that in the prednisone group(P =.012), but without significant difference compared with the model group(P =.051). The TM level in the JYSD group was the lowest(vs. the model group,P =.047;vs. the prednisone group, P =.006). Compared with the control group, the IOD values of VEGF and b FGF in the other three groups were lower(all P <.01). The IOD values of VEGF in the prednisone and JYSD groups were both higher than those in the model group(P =.002 and P <.001, respectively). The IOD values of b FGF among the model, prednisone, and JYSD groups were not statistically significant(P >.05).Conclusion: A vascular factor disorder is involved in the pathogenesis of ITP. JYSD can increase the platelet count, upregulate VEGF expression, and reduce the TM level. JYSD has the same effect as prednisone tablets in regulating platelet, v WF, VEGF, and b FGF, with a stronger effect in normalizing VCAM-1 and TM levels. The hemostatic mechanism of JYSD is closely related to the effective balance of vascular factors.

文摘The BRAF gene is an important signaling molecule in human cells that is involved in the regulation of cell growth,differentiation,and survival.When the BRAF gene mutates,it can lead to abnormal activation of the signaling pathway,which promotes cell proliferation,inhibits cell apoptosis,and ultimately contributes to the occurrence and development of cancer.BRAF mutations are widely present in various cancers,including malignant melanoma,thyroid cancer,colorectal cancer,non-small cell lung cancer,and hairy cell leukemia,among others.BRAF is an important target for the treatment of various solid tumors,and targeted combination therapies,represented by BRAF inhibitors,have become one of the main treatment modalities for a variety of BRAF-mutation-positive solid tumors.

文摘Objective:To investigate the anti-cancer effects and mechanism of modified Liangfu granule(MLFG)in BGC-823 gastric cancer cells.Methods:The drug serum was extracted from abdominal aorta of Wistar rats treated by cyclophosphamide,dioscin,MLFG(high-,medium-,and low-dose),respectively.MTS assay was performed to detect the effect of different concentrations of MLFG and dioscin on cell growth.The effect of MLFG on cellular apoptosis was detected by flow cytometry.Western blot was used to examine Bcl-2 and Akt in BGC-823 cells treated with MLFG.Quantitative real-time polymerase chain reaction assay was performed to determine the expression level of caspase-3,E2F1 and E2F3 genes in cells treated by MLFG-and dioscin-containing serum.Results:MLFG-and dioscin-containing serum inhibited the cell proliferation of BGC-823 cells.MLFG induced gastric carcinoma cell apoptosis and inhibited the expression of Bcl-2 and Akt in a dosedependent manner.MLFG also significantly induced the gene expression of caspase-3 and downregulated E2F1 and E2F3 gene expression.Conclusion:The effect of MLFG and dioscin on inhibiting cell proliferation and induction of apoptosis of gastric cancer cells might be related to the regulation of Bcl-2 and Akt proteins and the expression of caspase-3,E2F1 and E2F3 genes.
文摘Aim: To report a series of thirty cases of bisphosphonate-related osteonecrosis of the jaw (BRONJ). Material and Methods: For 30 patients with BRONJ, gender, age, underlying diagnosis, type of bisphosphonate (BP), administration route and duration, location and stage of osteonecrosis, symptoms and oral health status, radiological findings of the jaws, treatment and outcome, were recorded. Results: Underlying diagnoses in the series (12 male;18 female;mean age 70.50 ± 9.62) were: 12 multiple myeloma, 7 breast cancer, 3 prostate carcinoma, 1 kidney/lung/ bladder/mediastinal cancer, 1 chronic lymphocytic leukemia, 1 osteoporosis, 1 palatal osteosarcoma + osteoporosis, 1 non-Hodgkin’s lymphoma. Forty-seven osteonecrotic lesions were detected;30 localized in the mandible,17 inthe maxilla;trigger events were tooth extraction in 31 cases (66%), periodontal disease in 4 (8.50%), incongruous dentures in 3 (6.40%), perimplantitis in 1 (2.10%), unknown in 8 (17%). Twenty-nine patients had received treatment using amino bisphosphonates (25 zoledronate, 2 pamidronate, 2 alendronate) and 1 clodronate;the administration route was intravenous in 27 patients, oral in 2 and intramuscular in 1. Mean number of doses to bone exposure for patients was 34.11 for zoledronate, 50.50 for pamidronate, 146 for alendronate, and 500 for clodronate. Among statistical data the only significant finding was that panoramic dental radiography gave no concrete support for diagnosis of ONJ lesions (p ≤ 0.04). Conclusions: Our case series reflects literature data. We emphasize the insufficient role of panoramic radiography to study osteonecrotic lesions and the role of poor oral hygiene.
文摘We describe the effects of Darbepoietin-alfa (Darbe) administration in Multiple Myeloma (MM) after autologous he-mopoietic progenitor cell transplantation (AHPCT). 26 MM patients undergoing AHPCT entered this study. 34 hemo-globin (Hb)-matched patients who had not received recombinant human erythropoietin (Epo) or Darbe and were treated with the same protocol were retrospectively selected for comparative data. Darbe (150 micro g total dose/weekly) was initiating in four weeks after AHPCT, with the aim of achieving an Hb level of ≥11 g/dl. The time to response to Darbe therapy was longer in the patients with Hb < 10 g/dL (p = 0.05) and with endogenous Epo levels ≤ 50 mU/ml (p = 0.0098). Hb level on day 60 and 90 after AHPCT, was faster for Darbe recipients (12.5, range 9.4 - 15.4, vs 10.6, range 8.8 - 13.4 g/dL, p = 0.0001, and 13.5, range 12.3 - 14.3, vs 12, range 9.8 - 14 g/dL, respectively, p = 0.0001). The need for Red Blood Cells transfusion, included in the period of 30 - 90 days post- AHPCT was similar (p = ns). This study demonstrates the accelerating effect of Darbe on Hb increase in the setting evaluated and shows that this effect signify- cantly depends on the endogenous Epo level at the start of treatment. The strategy of giving Darbe around 1 month after high-dose melphalan (HDM) doesn’t reduce RBC transfusion requirement.
文摘Objective:To study the effect of preoperative Xiaoaiping combined with TEC neoadjuvant chemotherapy on malignant biological behaviors of breast cancer cells.Methods:The patients with breast cancer who received neoadjuvant chemotherapy in Renshou County People's Hospital between June 2014 and December 2017 were chosen as the research subjects and randomly divided into the combined group who accepted preoperative Xiaoaiping combined with TEC neoadjuvant chemotherapy and the control group who accepted TEC neoadjuvant chemotherapy. After surgical resection, the breast cancer lesion was taken to determine the mRNA expression of proliferation genes and invasion genes as well as the protein levels of angiogenesis molecules.Results: After surgical resection, USP39, CyclinD1, c-myc, Sema4D, CatB, ADAM17 and uPA mRNA expression as well as VEGF, Ang-2 and bFGF protein levels in breast cancer lesions of combined group were significantly lower than those of control group whereas TCEAL17, MFN2, TIMP1 and E-cadherin mRNA expression as well as MMRN2 and PEDF protein levels were significantly higher than those of control group.Conclusion:Xiaoaiping combined with TEC neoadjuvant chemotherapy before breast cancer surgery can be more effective than TEC neoadjuvant chemotherapy alone to inhibit the proliferation, invasion and angiogenesis of cancer cells.
文摘Objective:To analyze the levels of in vivo immunological indicators in patients with different types of malignanat lymphoma.Methods: A total of 69 patients with different types of malignanat lymphoma who were admitted in our hospital were included in the study, among which 31 had primary extranodular malignant lymphoma (extranodular group), and 38 had primary nodular malignant lymphoma (nodular group). Moreover, 34 patients with pure lymphnoditis were served as the control group. FCM and full-automatic speed scattering turbidimetry were used to detect T lymphocyte subsets proportion, IgG, IgA, IgM, C3, and C4 in the three groups.Results: The comparison of CD3+, CD4+, CD8+, NK cell proportion, and CD4+/CD8+ among the three groups was significantly different. When compared with the control group, CD3+, CD4+, CD8+, NK cell proportion, and CD4+/CD8+ in the extranodular group and nodular group were significantly reduced;moreover, CD3+, CD4+, CD8+, and CD4+/CD8+ in the extranodular group were significantly lower than those in the nodular group, while NK cell in the extranodular group was significantly higher than that in the nodular group. The comparison of IgG, IgA, and C3 levels among the three groups was statistically significant. When compared with the control group, IgG and IgA levels in the extranodular group and nodular group were significantly elevated, while C3 level was significantly reduced, and the comparison between the extranodular group and nodular group between the two groups was statistically significant. IgM level in the extranodular group and nodular group was elevated, C4 level was reduced, but the comparison with the control group was not statistically significant. Spearman correlation analysis showed that CD3+ and CD4+ were significantly correlated with IgA, IgG, and C3.Conclusions: With the increasing of severity degree of lymphoma, the immunological level is reduced, while CD3+ and CD4+ are significantly correlated with IgA, IgG, and C3, indicating that detection of CD3+ and CD4+ proportion or IgA, IgG, and C3 contents in combined with pathological characteristics can evaluate the severity degree of malignant lymphoma in order to provide guidance for the clinical diagnosis and treatment.
文摘Objective:To study the factors influencing the length of stay in patients with COVID-19.Methods:The clinical data of 110 patients with COVID-19 who were infected with Omicron virus for more than 10 days from April to May 2022 were collected.Their gender,age,smoking status,clinical manifestations related to pneumonia,whether they were combined with other basic diseases and vaccination status were analyzed.The above influencing factors were analyzed by single factor regression analysis,followed by Cox regression model analysis.Results:The age of patients had an effect on the length of hospital stay.The median length of hospital stay of patients that are<50 years old,50-64 years old and≥65 years old were 14,14,and 17 days respectively(χ^(2)=9.346,P=0.009).The presence of coronavirus-related symptoms also affects the length of hospital stay(χ^(2)=4.840,P=0.028).The results of multivariate regression model showed that age(χ^(2)=8.669,P=0.006)and coronavirus-related symptoms(χ^(2)=5.424,P=0.020)were independent factors affecting the length of hospital stay.Conclusion:During the development of COVID-19,the age of patients and whether they have coronavirus-related symptoms are positively correlated with the length of stay.Gender,habit of smoking,presence of other basic diseases and vaccination are not related to the length of stay.

文摘OBJECTIVE:To investigate the benefits of Traditional Chinese Medicine(TCM) therapy for improving the survival of patients with stage I gastric cancer(GC) and high-risk factors in a real-world setting.METHODS:The clinical data of patients who were diagnosed with stage I GC from March 1,2012 to October 31,2020 were collected.Prognostic analysis was performed to explore the high-risk factors that affected the survival of the patients.A Cox multivariate regression model was used to compare the hazard ratios for the mortality risk of patients,especially those with high-risk factors.Kaplan-Meier survival curve and log-rank test were utilized to assess the survival time.RESULTS:Prognostic analysis demonstrated that female sex,tumor invasion into blood vessels,and Ib stage were independent risk factors.The 1-,3-,and 5-year survival rates of the TCM group vs those of the non-TCM group were 100.0% vs 91.0%,97.6% vs 64.5%,and 81.4% vs 55.5%,respectively.A significant difference in median overall survival(m OS) was found between the two groups(χ2 = 7.670,P = 0.006).Subgroup analysis showed that the m OS of female patients and stage Ib patients in the TCM group were longer than those in the non-TCM group (P ≤ 0.001 and 0.001,respectively).CONCLUSIONS:TCM treatment can improve the survival of patients with stage I GC and high-risk factors.

文摘OBJECTIVE:To unmask the underlying mechanisms of Yisui granule(益髓颗粒,YSG)for the treatment of Myelodysplastic syndromes(MDS).METHODS:Our study used an SKM-1 mouse xenograft model of MDS to explore the anti-tumor potential of YSG and its safety,assess its effect on overall survival(OS),and evaluate whether its mechanism is associated with the demethylation of the secreted frizzled related protein 5(s FRP5)gene and suppressing Wnt/β-catenin pathway.Bisulfite amplicon sequencing was applied to detect the level of methylation of the s FRP5 gene;western blotting,immunofluorescence staining,and real-time Polymerase Chain Reaction were performed to detect DNA methyltransferase 1(DNMT1),s FRP5,and other Wnt/β-catenin pathway-related m RNA and protein expression.RESULTS:The results showed that high-dosage YSG exerted an anti-tumor effect similar to that of decitabine,improved OS,and reduced long-term adverse effects in the long term.Mechanically,YSG reduced the expression of DNMT1 methyltransferase,decreased the methylation,and increased the expression of the Wnt/β-catenin pathway antagonist-s FRP5.Furthermore,components of the Wnt/β-catenin pathway,including Wnt3a,β-catenin,c-Myc,and cyclin D1,were down-regulated in response to YSG,suggesting that YSG could treat MDS by demethylating the s FRP5 gene and suppressing the Wnt/β-catenin pathway.CONCLUSIONS:Our findings demonstrated that YSG could be used alone or in combination with decitabine to improve outcomes in the MDS animal model,providing an alternative solution for treating MDS.
