All the patients received a percutaneous liver biopsy guided by ultrasonography. LSM, biochemical tests, and complete blood cell counts were performed.RESULTS The pathological examination revealed moderate inflammatory necrosis ratios of 16.81%(16/95), 32.56%(28/86), and 45.31%(28/64), and moderate liverfibrosis of 24.2%(23/95), 33.72%(29/86), and 43.75%(28/64) in the PNALT, PIALT1, and PIALT2 groups, respectively. The degrees of inflammation and liver fibrosis were significantly higher in the PIALT groups than in the PNALT group(P < 0.05). No significant difference was found in the areas under the curve(AUCs) between APRI and FIB-4 in the PNALT group; however, significant differences were found between APRI and LSM, and between FIB-4 and LSM in the PNALT group(P < 0.05 for both). In the PIALT1 and PIALT2 groups, no significant difference(P > 0.05) was found in AUCs for all comparisons(P > 0.05 for all). In the overall patients, a significant difference in the AUCs was found only between LSM and APRI(P < 0.05).CONCLUSION APRI and FIB-4 are not the ideal noninvasive hepatic fibrosis markers for PNALT patients. LSM is superior to APRI and FIB-4 in PNALT patients because of the influence of liver inflammation and necrosis.展开更多

A 32-year-old woman with a history of acute hepatitis at age 9 years was found to have jaundice during pregnancy in 2008, and was diagnosed as having intrahepatic cholestasis of pregnancy. In 2009, she underwent cholecystectomy for gallstones and chronic cholecystitis. However, itching and jaundice did not resolve postoperatively. She was admitted to our hospital with fatigue, jaundice, and a recently elevated γ-glutamyl transpeptidase level. Liver biopsy led to the diagnosis of biliary cirrhosis with ductopenia. Genetic testing revealed a pathogenic heterozygous mutation, ex13 c.1531G > A (p.A511 T), in the ABCB4 gene. Her father did not carry the mutation, but her mother's brother carried the heterozygous mutation. We made a definitivediagnosis of familial intrahepatic cholestasis type 3. He symptoms and liver function improved after 3 mo o treatment with ursodeoxycholic acid.展开更多

Argon-helium cryotherapy is a local ablation method for HCC.CASE SUMMARY A 54-year-old man was diagnosed with HCC related to hepatitis B one year ago and underwent surgical tumor resection and tenofovir antiviral treatment.However, a new lesion developed on the right liver after 1 mo. Transarterial chemoembolization was performed four times. One month ago, the patient developed back pain, and metastasis on the 11 th thoracic vertebra was detected.Argon-helium cryoablation was performed to treat the right occupancy and metastatic lesion, which immediately alleviated the pain and prolonged survival.CONCLUSION The use of argon-helium cryoablation for thoracic vertebrae with metastasis of HCC achieved favorable results.展开更多

All mice were injected with concanavalin A(15 mg/kg) once a week. Moreover, Gc, Gd mice were injected weekly with IL-18(7.5 mg/kg) and anti-IL-18-m Ab(10 mg/kg) 2 hours before treatment with concanavalin A, respectively. Twenty-four hours after concanavalin A challenge at 1, 5, 12 and 20 weeks, 3 mice were killed by vena orbitalis, repectively. The sera were storaged at 4℃ for detecting of up TNF-α and IFN-γ by ELISA. The liver of mice in different groups were excised and fixed in 10% formalin for HE staining and Masson staining or frozen in liquid nitrogen for immunohistochemical staining for α-SMA. After extracting of total RNA from liver tissue, MMP-2 and TIMP-1A messenger RNA were amplified by reverse transcription polymerase chain reaction(PCR). Products were electrophoresed on agrose gel containing ethidium bromide and visualized under ultraviolet light. Densitometric RT-PCR data were standardized with β-actin signals. Results After experiment, the number of dead mice of Ga, Gb, Gc and Gd were 0, 6, 15 and 3, respectively. There were significant difference on each group(P < 0.05). At the fifth week of experiment, hepatocellular necrosis in IL-18 administered group mice had become widespread throughout the lobule. Evidence of liver fibrosis was observed during this period. However, at the twelfth week of experimemt, bridging fibrosis and large fibrosis strip in the parenchyma with hepatocellular necrosis was detectable in Gb, but at twentieth week, only the small fibrosis strip had been found in anti-IL-18-mA b administered group mice by HE staining and Masson staining. The serum levels of TNF-α and IFN-γ in IL-18 administered group were higher than that in concanavalin A group and anti-IL-18 administered groups(P < 0.05). Moreover, immunohistochemical staining for α-SMA indicated that the semi-quantu scores in IL-18 administered group were more than concanavalin A group and anti-IL-18-mA b administered groups(P < 0.05). MMP-2-mR NA, TIMP-1- mR NA expression levels increased signifigantly compared with concanavalin A group and anti-IL-18-mA b administered group(P < 0.05).Conclusions The immune liver fibrosis model induced by repeated injection of concanavalin A in BALB/c mice could be worsened by IL-18 administration and block by anti-IL-18 mA b administraion.展开更多
文摘BACKGROUND Stevens–Johnson syndrome and toxic epidermal necrolysis(SJS/TEN)are very serious skin allergies,with an etiology related to infections and medication.Since the coronavirus disease 2019(COVID-19)pandemic,severe acute respiratory syndrome coronavirus-2 has also been considered to cause SJS/TEN.CASE SUMMARY We report the case of a woman in her thirties who took acetaminophen after contracting COVID-19.After 3 d of fever relief,she experienced high fever and presented with SJS/TEN symptoms,accompanied by intrahepatic cholestasis.Three days of corticosteroid treatment did not alleviate the skin damage;therefore,double plasma molecular adsorption system(DPMAS)therapy was initiated,with treatment intervals of 48 h.Her skin symptoms improved gradually and were resolved after seven DPMAS treatments.CONCLUSION DPMAS therapy is beneficial for abrogating SJS/TEN because plasma adsorption and perfusion techniques reduce the inflammatory mediators(e.g.,tumor necrosis factor-alpha and interleukin-10 and-12)speculated to be involved in the pathology of the skin conditions.

文摘AIM:To investigate the prevalence of nature tyrosinemethionine-aspartic acid-aspartic acid motif mutations in chronic hepatitis B(CHB)patients and to evaluate the efficacy of lamivudine.METHODS:A total of 1268 CHB patients were recruited from the outpatient and inpatient departments of six centers.Tyrosine-methionine-aspartic acid-aspartic acid(YMDD)mutations were analyzed using the hepatitis B virus(HBV)drug resistance line probe assay.Forty voluntary patients were selected from those with positive or negative natural YMDD mutations to undergo treatment with lamivudine.RESULTS:YMDD mutations were detected in 288(22.71%)of the 1268 CHB patients.Multivariate analysis revealed that the patients’HBV DNA level(P=0.0282)and hepatitis B e antigen status(P=0.0133)were also associated with natural YMDD mutations.The rates of normalization of alanine aminotransferase levels and HBV DNA nondetection at 6,24,36,and 48 wk were compared between the patients with natural YMDD mutations and those without,and the differences were not significant.However,there was a significant difference in the cumulative emergence rates of virological breakthrough at 48 wk in the patients with natural YMDD mutations and those without(32.5%vs 12.5%,P=0.032).CONCLUSION:Naturally occurring YMDD mutationsare detectable in a large proportion of CHB patients;breakthrough hepatitis tended to occur in patients with natural YMDD mutations.
文摘BACKGROUND The portosystemic shunt is the pathway between the portal vein (PV) and systemic circulation.A spontaneous intrahepatic portosystemic shunt (SPISS) is a rare portosystemic shunt type.Here we report an extremely rare type of SPISS,a spontaneous intrahepatic PV-inferior vena cava shunt (SPIVCS).CASE SUMMARY A 66-year-old woman was admitted to our hospital with the complaint of abdominal distention and a decreased appetite for 1 mo.The patient had a 20- year history of hepatitis B surface antigen positivity and a 5-year history of cirrhosis.She had been treated with Chinese herbal medicine for a long time.Liver function tests showed: alanine aminotransferase,35 U/L;aspartate aminotransferase,42 U/L;serum albumin (ALB) 32.2 g/L;and serum ascites ALB gradient,25.2 g/L.Abdominal ultrasonography and enhanced computed tomography showed that the left branch of the PV was thin and occluded;the right branch of the PV was thick and showed a vermicular dilatation vein cluster in the upper pole of the right kidney that branched out and converged into the inferior vena cava from the bare area of the lower right posterior lobe of the liver.We diagnosed her with an extremely rare SPIVCS caused by portal hypertension and provided symptomatic treatment after admission.One week later,her symptoms disappeared and she was discharged.CONCLUSION SPIVCS is a rare portosystemic shunt with a clear history of cirrhosis and portal hypertension.Clarifying the type PV shunt has important clinical significance.
文摘BACKGROUND The immune-mediated invasion of IgG4-positive plasma cells in the liver is found in some autoimmune hepatitis.Giant-cell hepatitis(GCH)is a very rare pathological feature in adults,and the clinical characteristics of the simultaneous appearance of the two pathological phenomena are not clear.CASE SUMMARY A 68-year-old woman was hospitalized with fatigue,poor appetite,and yellow urine for 20 d.Liver function tests and immunological indexes were significantly abnormal and accompanied by elevated serum IgG4 levels.Liver pathology revealed severe inflammation of the interface between the portal tract and hepatocytes,portal area inflammation,plasma cell infiltration,formation of rosette cells,IgG4-positive plasma cells>10/high-power field,IgG4/IgG>40%,and multinucleated liver cell swelling.IgG4-related autoimmune hepatitis(AIH)combined with GCH was diagnosed,and methylprednisolone was administered at 40 mg/day.Two weeks later,the clinical symptoms disappeared,and the liver function and immunological indicators were significantly improved.Methylprednisolone was reduced at a rate of 4–8 mg per week to 8 mg/day for maintenance.A second liver biopsy 48 wk later indicated that liver inflammation and fibrosis were significantly improved.IgG4-positive plasma cells and GCH were not detected.A literature search was conducted to analyze articles reporting similar pathological phenomena.CONCLUSION AIH with simultaneous IgG4-positive plasma cell infiltration and GCH,liver inflammation,and fibrosis is possibly more severe than typical AIH but sensitive to corticosteroids.

文摘BACKGROUND Although many studies have investigated the impact of chronic hepatitis B virus(HBV)infection and nonalcoholic fatty liver disease(NAFLD)on liver disease,few have investigated the relationship between nonalcoholic steatohepatitis(NASH)defined by liver pathology and the prognosis of chronic HBV infection.Most patients were followed up for a short time.This study aimed to further explore the impact of NAFLD and the pathological changes confirmed by liver pathology in patients with chronic HBV infection.AIM To study the effect of NAFLD confirmed using liver pathology on the outcomes of long-term serious adverse events[cirrhosis,hepatocellular carcinoma(HCC),and death]in patients with chronic hepatitis B(CHB)virus infection.METHODS We enrolled patients with chronic hepatitis B virus(HBV)infection who underwent liver biopsy at the Third People’s Hospital of Zhenjaing Affiliated Jiangsu University between January 2005 and September 2020.Baseline clinical and pathological data on liver pathology and clinical data at the end of follow-up were collected.Propensity score matching(PSM)was used to balance baseline parameters,Kaplan-Meier(K-M)survival analysis was used to evaluate the risk of clinical events,and Cox regression was used to analyze the risk factors of events.RESULTS Overall,456 patients with chronic HBV infection were included in the study,of whom 152(33.3%)had histologically confirmed NAFLD.The median follow-up time of the entire cohort was 70.5 mo.Thirty-four patients developed cirrhosis,which was diagnosed using ultrasound during the follow-up period.K-M survival analysis showed that NAFLD was not significantly associated with the risk of cirrhosis(log-rank test,P>0.05).Patients with CHB with fibrosis at baseline were more prone to cirrhosis(log-rank test,P=0.046).After PSM,multivariate analysis showed that diabetes mellitus,ballooning deformation(BD),and platelet(PLT)were independent risk factors for cirrhosis diagnosed using ultrasound(P<0.05).A total of 10 patients(2.2%)developed HCC,and six of these patients were in the combined NAFLD group.K-M survival analysis showed that the cumulative risk of HCC in the NAFLD group was significantly higher(log-rank test,P<0.05).Hepatocyte ballooning,and severe liver fibrosis were also associated with an increased risk of HCC(log-rank test,all P<0.05).Cox multivariate analysis revealed that hepatocyte ballooning,liver fibrosis,and diabetes mellitus were independent risk factors for HCC.CONCLUSION There was no significant correlation between chronic HBV infection and the risk of cirrhosis in patients with NAFLD.Diabetes mellitus,BD,and PLT were independent risk factors for liver cirrhosis.Patients with chronic HBV infection and NASH have an increased risk of HCC.BD,liver fibrosis,and diabetes mellitus are independent risk factors for HCC.

文摘BACKGROUND Only a few cases of chronic hepatitis B(CHB)with primary biliary cholangitis(PBC)have been reported based on histological evidence from liver biopsies.AIM To observe the clinicopathological features and outcomes of 11 patients with CHB infection complicated by PBC.METHODS Eleven patients with CHB and PBC who underwent liver biopsy at the Zhenjiang Third Hospital,affiliated with Jiangsu University,and Wuxi Fifth People’s Hospital,from January 2005 to September 2020,were selected.All patients initially visited our hospital with CHB and were pathologically diagnosed with CHB and PBC.RESULTS Only five had elevated alkaline phosphatase levels,nine were positive for antimitochondrial antibody(AMA)-M2,and two were negative for AMA-M2.Two had jaundice and pruritus symptoms,10 had mildly abnormal liver function,and one had severely elevated bilirubin and liver enzyme levels.The pathological characteristics of CHB complicated by PBC overlapped with those of PBCautoimmune hepatitis(AIH).When necroinflammation of the portal area is not obvious,the pathological features of PBC are predominant,similar to the features of PBC alone.When the interface is severe,biliangitis will occur,with a large number of ductular reactions in zone 3.Unlike the PBC-AIH overlap pathology,this pathology is characterized by a small amount of plasma cell infiltration.Unlike PBC,lobulitis is often observed.CONCLUSION This is the first large case series to show that the rare pathological features of CHB with PBC are similar to those of PBC-AIH and small duct injury was observed.
文摘BACKGROUND Radiofrequency ablation(RFA)is an effective and safe treatment for hepatocellular carcinoma that features a lower incidence of serious complications than surgical resection.Hemocholecyst caused by RFA is a rare complication of secondary damage to the intrahepatic bile duct that results in hemobilia.CASE SUMMARY Here we report on a case of a hemocholecyst caused by accidental injury during RFA that induced hematemesis and melena.Digital subtraction angiography revealed no gallbladder arterial injuries.After conservative treatment and transcatheter arterial chemoembolization,the patient’s condition stabilized,and she was discharged 1 wk later.CONCLUSION Therefore,when performing interventional procedures such as RFA,clinicians must be vigilant because even minor injuries can lead to serious complications such as hemocholecyst.
文摘AIM To assess the diagnostic value of FIB-4, aspartate aminotransferase-to-platelet ratio index(APRI), and liver stiffness measurement(LSM) in patients with hepatitis B virus infection who have persistently normal alanine transaminase(PNALT).METHODS We enrolled 245 patients with chronic hepatitis B: 95 in PNALT group, 86 in intermittently elevated alanine transaminase(PIALT1) group [alanine transaminase(ALT) within 1-2 × upper limit of normal value(ULN)], and 64 in PIALT2 group(ALT > 2 × ULN). All the patients received a percutaneous liver biopsy guided by ultrasonography. LSM, biochemical tests, and complete blood cell counts were performed.RESULTS The pathological examination revealed moderate inflammatory necrosis ratios of 16.81%(16/95), 32.56%(28/86), and 45.31%(28/64), and moderate liverfibrosis of 24.2%(23/95), 33.72%(29/86), and 43.75%(28/64) in the PNALT, PIALT1, and PIALT2 groups, respectively. The degrees of inflammation and liver fibrosis were significantly higher in the PIALT groups than in the PNALT group(P < 0.05). No significant difference was found in the areas under the curve(AUCs) between APRI and FIB-4 in the PNALT group; however, significant differences were found between APRI and LSM, and between FIB-4 and LSM in the PNALT group(P < 0.05 for both). In the PIALT1 and PIALT2 groups, no significant difference(P > 0.05) was found in AUCs for all comparisons(P > 0.05 for all). In the overall patients, a significant difference in the AUCs was found only between LSM and APRI(P < 0.05).CONCLUSION APRI and FIB-4 are not the ideal noninvasive hepatic fibrosis markers for PNALT patients. LSM is superior to APRI and FIB-4 in PNALT patients because of the influence of liver inflammation and necrosis.
文摘BACKGROUND Thyroid storm is resistant to conventional treatments including antithyroid drugs and 131I therapeutic means.Plasma exchange(PE)and double plasma molecular absorption system(DPMAS)can be used as an effective treatment for thyroid storm with severe liver injury.CASE SUMMARY A 52-year-old woman presented with a 10-day history of nausea and vomiting accompanied by yellowing of the skin and mucosa.Further,her free T3(FT3)and FT4 levels were significantly elevated,whereas her thyrotropin level was reduced.After admission,her condition continued to deteriorate,and she presented with continued high fever,vomiting,palpitation,and shortness of breath.After being diagnosed with thyroid storm,the patient was immediately treated with PE combined with DPMAS.Her symptoms improved immediately.After three PE+DPMAS treatments,and she was discharged from the hospital.She was treated with methylprednisolone and methylthimidazole.After six months,the patient spontaneously discontinued methylthimidazole treatment.Her previous clinical manifestations and liver dysfunction reoccurred.The patient was treated with PE+DPMAS two times,and her condition rapidly improved.Liver histopathology indicated immunological liver injury.CONCLUSION Our experience suggests that PE combined with DPMAS can effectively relieve the development of thyroid storm.
文摘Progressive familial intrahepatic cholestasis type 3 is caused by a mutation in the ATP-binding cassette, subfamily B, member 4 (ABCB4) gene encoding multidrug resistance protein 3. A 32-year-old woman with a history of acute hepatitis at age 9 years was found to have jaundice during pregnancy in 2008, and was diagnosed as having intrahepatic cholestasis of pregnancy. In 2009, she underwent cholecystectomy for gallstones and chronic cholecystitis. However, itching and jaundice did not resolve postoperatively. She was admitted to our hospital with fatigue, jaundice, and a recently elevated γ-glutamyl transpeptidase level. Liver biopsy led to the diagnosis of biliary cirrhosis with ductopenia. Genetic testing revealed a pathogenic heterozygous mutation, ex13 c.1531G > A (p.A511 T), in the ABCB4 gene. Her father did not carry the mutation, but her mother's brother carried the heterozygous mutation. We made a definitivediagnosis of familial intrahepatic cholestasis type 3. He symptoms and liver function improved after 3 mo o treatment with ursodeoxycholic acid.
文摘BACKGROUND Immune checkpoint inhibitors(ICIs)can lead to immune-related hepatitis(IRH)and severe liver damage,which is life-threatening in the absence of specific treatment.CASE SUMMARY A 75-year-old man was admitted to our hospital complaining of loss of appetite,yellow urine,and abnormal liver function for the past 2 wk.Three months prior to admission,he was treated with two rounds of capecitabine in combination with camrelizumab for lymph node metastasis of esophageal cancer.Although liver function was normal before treatment,abnormal liver function appeared at week 5.Capecitabine and camrelizumab were discontinued.Ursodeoxycholic acid and methylprednisolone 40 mg daily were administered.Liver function continued to deteriorate.Prothrombin time and international normalized ratio were 19 s and 1.8,respectively.The patient was diagnosed with acute liver failure.A pathological analysis of liver biopsy indicated a strongly positive immunohistochemical staining of T8+cells,thereby suggesting that drug-induced liver injury was related to IRH caused by camrelizumab.Subsequently,we performed sequential dual-molecule plasma adsorption system(DPMAS)treatment with plasma exchange(PE).After two rounds of treatment,the patient's appetite significantly improved,the yellow color of urine reduced,and liver function improved(total bilirubin level decreased)after five rounds of treatment.Liver function normalized 4 wk after discharge.CONCLUSION The use of sequential DPMAS with PE can reduce liver injury and systemic toxic reactions by clearing inflammatory mediators and harmful substances from blood,and regulate immune cell activity,which may be effective in the treatment of severe ICI-induced IRH.

文摘BACKGROUND The artificial liver support system(ALSS)is an effective treatment method for liver failure,but it requires deep venous intubation and long-term indwelling catheterization.However,the coagulation mechanism disorder of basic liver failure diseases,and deep venous thrombosis(DVT)often occur.AIM To evaluate the risk factors for DVT following use of an ALSS and establish a risk assessment score.METHODS This study was divided into three stages.In the first stage,the risk factors for DVT were screened and the patient data were collected,including ALSS treatment information;biochemical indices;coagulation and hematology indices;complications;procoagulant use therapy status;and a total of 24 indicators.In the second stage,a risk assessment score for DVT after ALSS treatment was developed.In the third stage,the DVT risk assessment score was validated.RESULTS A total of 232 patients with liver failure treated with ALSS were enrolled in the first stage,including 12 with lower limb DVT.Logistic regression analysis showed that age[odds ratio(OR),1.734;P=0.01],successful catheterization time(OR,1.667;P=0.005),activity status(strict bed rest)(OR,3.049;P=0.005),and D-dimer level(≥500 ng/mL)(OR,5.532;P<0.001)were independent risk factors for DVT.We then established a scoring system for risk factors.In the validation group,a total of 213 patients with liver failure were treated with ALSS,including 14 with lower limb DVT.When the cutoff value of risk assessment was 3,the specificity and sensitivity of the risk assessment score were 88.9%and 85.7%,respectively.CONCLUSION A simple risk assessment scoring system was established for DVT patients with liver failure treated with ALSS and was verified to have good sensitivity and specificity.
文摘Hematopoietic stem cell transplantation(HSCT)-sinusoidal obstruction syndrome(SOS),also known as veno-occlusive disease,is a clinical syndrome characterized by symptoms,such as right upper quadrant pain,jaundice,fluid retention,and hepatomegaly,and is caused by pre-treatment-related hepatotoxicity during the early stages after HSCT.Clinical diagnosis of HSCT-SOS is based on the revised Seattle or Baltimore standards.The revised standard by the European Society for Bone Marrow Transplantation in 2016 has good practicability and can be used in combination with these two standards.Eight studies have shown the value of liver stiffness measurement(LSM)in the early diagnosis of HSCT-SOS.Four studies investigated LSM specificity and sensitivity for the early diagnosis of HSCT-SOS.LSM can distinguish SOS from other post-HSCT complications,enabling a clear differential diagnosis.It has been shown that median LSM of patients with SOS is significantly higher than that of patients with other treatment-related liver complications(e.g.,acute cholecystitis,cholangitis,antifungal drug-related liver injury,liver graft-versus-host disease,isolated liver biochemical changes,and fulminant Epstein Barr virus related hepatitis reactivation).Therefore,the above data confirmed the utility of LSM and strongly suggested that LSM improves the positive predictive value of the SOS diagnostic clinical score after allogeneic HSCT.Early diagnosis of SOS is beneficial in preventing severe HSCT complications.

文摘The risk stratification of primary liver cancer(PLC)discussed in a review of viral hepatitis and PLC could lead to misunderstandings by readers.For example,a single study or a small number of studies cannot comprehensively summarize the risk factors of PLC,is not included in the family history of liver cancer,and chronic hepatitis D is listed as a medium risk factor for the development of PLC.Currently,PLC prediction models with good clinical validation values have been applied clinically,such as the Toronto hepatocellular carcinoma risk index,REACH-B model,and PAGE-B model.Therefore,the Chinese,together with several research societies,have formulated the“Guideline for stratified screening and surveillance of primary liver cancer(2020 edition).”This guideline outlines PLC screening in at-risk populations,both in hospitals and communities.It is recommended to stratify the at-risk population into four risk levels:low-,intermediate-,high-,and extremely high-risk.This is highly recommended and applied in clinical practice.
文摘Nilotinib is a specific breakpoint cluster region-Abelson leukemia virus-tyrosine kinase inhibitor that is used as an effective first-or second-line treatment in imatinib-resistant chronic myelogenous leukemia(CML)patients.Hepatotoxicity due to nilotinib is a commonly reported side effect;however,abnormal liver function test(LFT)results have been reported in asymptomatic cases.When alanine aminotransferase(ALT)and aspartate aminotransferase(AST)levels are more than five-fold the upper limit of the normal(ULN)or when the serum total bilirubin level is more than three-fold the ULN,dose modification or discontinuation of nilotinib is recommended,resulting in decreased levels of hematological indicators in certain patients with CML.Nilotinib-induced hyperbilirubinemia typically manifests as indirect bilirubinemia without elevated ALT or AST levels.Such abnormal liver functioning is thus not attributed to the presence of a true histologic lesion of the liver.The underlying mechanism may be related to the inhibition of uridine diphosphate glucuronosyltransferase activity.Therefore,nilotinib dose adjustment is not recommended for this type of hyperbilirubinemia,and in the absence of elevated liver enzyme levels or presence of abnormal LFT findings,physicians should consider maintaining nilotinib dose intensity without modifications.
文摘BACKGROUND Spinal metastasis of hepatocellular carcinoma(HCC) is rare, with an extremely poor prognosis and results in severe pain. Argon-helium cryotherapy is a local ablation method for HCC.CASE SUMMARY A 54-year-old man was diagnosed with HCC related to hepatitis B one year ago and underwent surgical tumor resection and tenofovir antiviral treatment.However, a new lesion developed on the right liver after 1 mo. Transarterial chemoembolization was performed four times. One month ago, the patient developed back pain, and metastasis on the 11 th thoracic vertebra was detected.Argon-helium cryoablation was performed to treat the right occupancy and metastatic lesion, which immediately alleviated the pain and prolonged survival.CONCLUSION The use of argon-helium cryoablation for thoracic vertebrae with metastasis of HCC achieved favorable results.
文摘Objective To explore the prevention of IL-18 or anti-IL-18-m Ab to the immune liver fibrosis model induced by repeated injection of concanavalin A in BALB/c mice and its mechanism.Methods Total of 120 BALB/c mice were divided into four groups, control group mice(Ga) were injected weekly with normal saline, concanavalin A group was divided into Gb, Gc, Gd. All mice were injected with concanavalin A(15 mg/kg) once a week. Moreover, Gc, Gd mice were injected weekly with IL-18(7.5 mg/kg) and anti-IL-18-m Ab(10 mg/kg) 2 hours before treatment with concanavalin A, respectively. Twenty-four hours after concanavalin A challenge at 1, 5, 12 and 20 weeks, 3 mice were killed by vena orbitalis, repectively. The sera were storaged at 4℃ for detecting of up TNF-α and IFN-γ by ELISA. The liver of mice in different groups were excised and fixed in 10% formalin for HE staining and Masson staining or frozen in liquid nitrogen for immunohistochemical staining for α-SMA. After extracting of total RNA from liver tissue, MMP-2 and TIMP-1A messenger RNA were amplified by reverse transcription polymerase chain reaction(PCR). Products were electrophoresed on agrose gel containing ethidium bromide and visualized under ultraviolet light. Densitometric RT-PCR data were standardized with β-actin signals. Results After experiment, the number of dead mice of Ga, Gb, Gc and Gd were 0, 6, 15 and 3, respectively. There were significant difference on each group(P < 0.05). At the fifth week of experiment, hepatocellular necrosis in IL-18 administered group mice had become widespread throughout the lobule. Evidence of liver fibrosis was observed during this period. However, at the twelfth week of experimemt, bridging fibrosis and large fibrosis strip in the parenchyma with hepatocellular necrosis was detectable in Gb, but at twentieth week, only the small fibrosis strip had been found in anti-IL-18-mA b administered group mice by HE staining and Masson staining. The serum levels of TNF-α and IFN-γ in IL-18 administered group were higher than that in concanavalin A group and anti-IL-18 administered groups(P < 0.05). Moreover, immunohistochemical staining for α-SMA indicated that the semi-quantu scores in IL-18 administered group were more than concanavalin A group and anti-IL-18-mA b administered groups(P < 0.05). MMP-2-mR NA, TIMP-1- mR NA expression levels increased signifigantly compared with concanavalin A group and anti-IL-18-mA b administered group(P < 0.05).Conclusions The immune liver fibrosis model induced by repeated injection of concanavalin A in BALB/c mice could be worsened by IL-18 administration and block by anti-IL-18 mA b administraion.
