BACKGROUND Albumin-bound paclitaxel(ABP)has been used as second-and higher-line treatments for advanced esophageal cancer,and its efficacy and safety have been well demonstrated.Lobaplatin(LBP)is a third-generation platinum antitumor agent;compared with the first two generations of platinum agents,it has lower toxicity and has been approved for the treatment of breast cancer,small cell lung cancer,and chronic granulocytic leukemia.However,its role in the treatment of esophageal cancer warrants further investigations.AIM To investigate the efficacy and safety of induction chemotherapy with ABP plus LBP followed by concurrent radiochemotherapy(RCT)for locally advanced esophageal cancer.METHODS Patients with pathologically confirmed advanced esophageal squamous cell carcinoma(ESCC)at our hospital were enrolled in this study.All patients were treated with two cycles of induction chemotherapy with ABP plus LBP followed by concurrent RCT:ABP 250 mg/m^(2),ivgtt,30 min,d1,every 3 wk;and LBP,30 mg/m^(2),ivgtt,2 h,d1,every 3 wk.A total of four cycles were scheduled.The dose of the concurrent radiotherapy was 56-60 Gy/28-30 fractions,1.8-2.0 Gy/fraction,and 5 fractions/wk.RESULTS A total of 29 patients were included,and 26 of them completed the treatment protocol.After the induction chemotherapy,the objective response rate(ORR)was 61.54%,the disease control rate(DCR)was 88.46%,and the progressive disease(PD)rate was 11.54%;after the concurrent RCT,the ORR was 76.92%,the DCR was 88.46%,and the PD rate was 11.54%.The median progression-free survival was 11.1 mo and the median overall survival was 15.83 mo.Cox multivariate analysis revealed that two cycles of induction chemotherapy followed by concurrent RCT significantly reduced the risk of PD compared with two cycles of chemotherapy alone(P=0.0024).Non-hematologic toxicities were tolerable,and the only grade 3 non-hematologic toxicity was radiation-induced esophagitis(13.79%).The main hematologic toxicity was neutropenia,and no grade 4 adverse event occurred.CONCLUSION Induction chemotherapy with ABP plus LBP followed by concurrent RCT is effective in patients with locally advanced ESCC,with mild adverse effects.Thus,this protocol is worthy of clinical promotion and application. 展开更多

Objective: To study the effects of preoperative concurrent radiochemotherapy on the cancer cell infiltration and angiogenesis in local advanced gastric cancer lesions. Methods: A total of 68 patients who were diagnosed with locally advanced gastric cancer in this hospital between February 2015 and April 2017 were selected as the research subjects and randomly divided into two groups, the radiochemotherapy group received capecitabine + cisplatin chemotherapy combined with intensity modulated radiation therapy before operation, and chemotherapy group received preoperative capecitabine + cisplatin chemotherapy. The gastric cancer lesions surgically removed from two groups of patients were collected to determine the expression of proliferation-related genes, invasion-related genes and angiogenesis-related genes. Results:Rab27B, Bax, Caspase-3, PTPN13, E-cadherin and THBS2 protein expression in gastric cancer lesions of radiochemotherapy group were greatly higher than those of chemotherapy group whereas EZH2, PRR1, EPHA2, HDAC5, N-cadherin, Twist1, ANGPTL2, ANGPTL5, GOLPH3 and HIF-1 protein expression were greatly lower than those of chemotherapy group. Conclusion: Preoperative concurrent radiochemotherapy has inhibitory effect on the cancer cell infiltration and angiogenesis in local advanced gastric cancer lesions. 展开更多

Objective:To study the effect of cisplatin-based concurrent radiochemotherapy on the malignant degree of advanced cervical cancer and the expression of proto-oncogene and tumor suppressor genes.Methods: A total of 82 patients with advanced cervical cancer who were treated in our hospital between July 2013 and December 2016 were collected and divided into control group and observation group according to random number table, with 41 cases in each group. The control group of patients received radiotherapy alone, while the observation group of patients received cisplatin-based concurrent radiochemotherapy. Tumor marker levels in serum as well as proto-oncogene and tumor suppressor gene expression in tumor tissue were compared between two groups of patients before and after treatment.Results:Before treatment, differences in tumor marker levels in serum as well as proto-oncogene and tumor suppressor gene expression in tumor tissue were not statistically significant between two groups of patients. After treatment, serum tumor markers SCC, CA50, CA724 and CEA levels of observation group were significantly lower than those of control group;proto-oncogene DEK, c-myc and PIK3CA mRNA expression in tumor tissue were significantly lower than those of control group;tumor suppressor genes p53, SOCS-1, FHIT and PTEN mRNA expression in tumor tissue were significantly higher than those of control group.Conclusions:Cisplatin-based concurrent radiochemotherapy can effectively reduce the tumor malignancy and balance the proto-oncogene / tumor suppressor gene expression in patients with advanced cervical cancer. 展开更多

The frequency and duration of observed concurrent hot and dry events(HDEs) over China during the growing season(April–September) exhibit significant decadal changes across the mid-1990s. These changes are characterized by increases in HDE frequency and duration over most of China, with relatively large increases over southeastern China(SEC), northern China(NC), and northeastern China(NEC). The frequency of HDEs averaged over China in the present day(PD,1994–2011) is double that in the early period(EP, 1964–81);the duration of HDEs increases by 60%. Climate experiments with the Met Office Unified Model(MetUM-GOML2) are used to estimate the contributions of anthropogenic forcing to HDE decadal changes over China. Anthropogenic forcing changes can explain 60%–70% of the observed decadal changes,suggesting an important anthropogenic influence on HDE changes over China across the mid-1990s. Single-forcing experiments indicate that the increase in greenhouse gas(GHG) concentrations dominates the simulated decadal changes,increasing the frequency and duration of HDEs throughout China. The change in anthropogenic aerosol(AA) emissions significantly decreases the frequency and duration of HDEs over SEC and NC, but the magnitude of the decrease is much smaller than the increase induced by GHGs. The changes in HDEs in response to anthropogenic forcing are mainly due to the response of climatological mean surface air temperatures. The contributions from changes in variability and changes in climatological mean soil moisture and evapotranspiration are relatively small. The physical processes associated with the response of HDEs to GHG and AA changes are also revealed. 展开更多

BACKGROUND Currently,there is no standard adjuvant therapy for patients with resected ampulla of Vater(AoV)cancer.AIM To evaluate the effectiveness of adjuvant concurrent chemoradiotherapy(CCRT)in patients with advanced AoV cancer who underwent curative resection.METHODS This single-centered,retrospective study included 29 patients with advanced AoV cancer who underwent pancreaticoduodenectomy between 2006 and 2018.The impact of CCRT on advanced AoV cancer was analyzed.RESULTS The 1-,3-,and 5-yr recurrence-free survival(RFS)rates for patients with advanced AoV cancer were 82.8%,48.3%,and 40.8%,respectively,and the overall survival(OS)rates were 89.7%,62.1%,and 51.7%,respectively.Lymphovas-cular invasion was found to be a significant risk factor for RFS and OS in patients with advanced AoV cancer in the univariate analysis,whereas T stage and lymph node metastasis were significantly associated with OS in the multivariate analysis.Compared to the patients who did not receive adjuvant CCRT,those who received adjuvant CCRT did not show statistically significant improvements in the RFS and OS,although they had a significantly lower average age and significantly higher platelet-to-lymphocyte ratio.CONCLUSION Adjuvant CCRT did not improve survival outcomes in patients with advanced AoV cancer.These findings contribute to existing knowledge on the effectiveness of CCRT in this patient population and provide important insights for clinical decision-making. 展开更多

Background::Recently,T-helper 17(Th17)cells have been proved to play an important role in promoting cervical cancer.But,till now,few study has been carried out to understand the involvement of these cells in efficacy of anti-tumor treatments.This study aimed to investigate the alterations in the percentage of circulating Th17 cells and related cytokines in locally advanced cervical cancer(LACC)patients before and after concurrent chemoradiotherapy(cCRT)and to analyze the correlations between the alterations in Th17 cells and treatment efficacy.Methods::A prospective study with 49 LACC(International federation of gynecology and obstetrics[FIGO]stage IIB-IIIB)patients and 23 controls was conducted.Patients received the same cCRT schedule and were followed up for 3 years.Circulating Th17 cells(CD3+CD8-interleukin[IL]-17+T cells)and related cytokines IL-17,transforming growth factor-β(TGF-β),IL-10,IL-23,IL-6,and IL-22 were detected before and after cCRT.Correlations between alterations of circulating Th17 cells and treatment efficacy were analyzed.Kaplan-Meier analysis was used for overall survival(OS)and progression-free survival(PFS).Results::We found that 40 patients finished the entire cCRT schedule and met the endpoint of this study.The percentage of circulating Th17 cells in the LACC patients was higher than that in the controls,and it significantly decreased after cCRT(P<0.05).After cCRT,patients were divided into two groups based on the average of the Th17 cells declined.The subgroup of patients with a prominent decrease in circulating Th17 cells after cCRT had a higher treatment efficacy and longer PFS and OS times.Compared with the control patients,LACC patients had higher IL-6,IL-10,IL-22,TGF-βlevels and a lower IL-23 level(P<0.05).After cCRT,IL-6,IL-10,IL-17,IL-23 level significantly increased and TGF-βlevel significantly decreased compared with the levels before cCRT(P<0.05).Conclusion::Circulating Th17 cells in the LACC patients(FIGO stage IIB-IIIB)were higher than those in the controls,but they generally decreased after cCRT.A more pronounced decrease in circulating Th17 cells after cCRT was correlated with better therapeutic effect and longer PFS and OS times. 展开更多

BACKGROUND Although the current conventional treatment strategies for esophageal carcinoma(EC)have been proven effective,they are often accompanied by serious adverse events.Therefore,it is still necessary to continue to explore new therapeutic strategies for EC to improve the clinical outcome of patients.AIM To elucidate the clinical efficacy of concurrent chemoradiotherapy(CCRT)with thalidomide(THAL)and S-1(tegafur,gimeracil,and oteracil potassium capsules)in the treatment of EC as well as its influence on serum tumor markers(STMs).METHODS First,62 patients with EC treated at the Zibo 148 Hospital between November 2019 and November 2022 were selected and grouped according to the received treatment.Among these,30 patients undergoing CCRT with cis-platinum and 5-fluorouracil were assigned to the control group(Con),and 32 patients receiving CCRT with THAL and S-1 were assigned to the research group(Res).Second,inter-group comparisons were carried out with respect to curative efficacy,incidence of drug toxicities,STMs[carbohydrate antigen 125(CA125)and macrophage inflammatory protein-3α(MIP-3α)],angiogenesis-related indicators[vascular endothelial growth factor(VEGF);VEGF receptor-1(VEGFR-1);basic fibroblast growth factor(bFGF);angiogenin-2(Ang-2)],and quality of life(QoL)[QoL core 30(QLQ-C30)]after one month of treatment.RESULTS The analysis showed no statistical difference in the overall response rate and disease control rate between the two patient cohorts;however,the incidences of grade I–II myelosuppression and gastrointestinal reactions were significantly lower in the Res than in the Con.Besides,the post-treatment CA125,MIP-3α,VEGF,VEGFR-1,bFGF,and Ang-2 Levels in the Res were markedly lower compared with the pre-treatment levels and the corresponding post-treatment levels in the Con.Furthermore,more evident improvements in QLQ-C30 scores from the dimensions of physical,role,emotional,and social functions were determined in the Res.CONCLUSION The above results demonstrate the effectiveness of THAL+S-1 CCRT for EC,which contributes to mild side effects and significant reduction of CA125,MIP-3α,VEGF,VEGFR-1,bFGF,and Ang-2 Levels,thus inhibiting tumors from malignant progression and enhancing patients’QoL. 展开更多

Prior to his initial diagnosis, a 21-year-old male had been experiencing facial acne for two years and had been treated by a doctor in private practice. The patient visited our department because the clinical manifestations of mandibular acne did not improve. At the time of initial examination, telangiectasia (TE), post-inflammatory erythema (PIE), post-inflammatory hyperpigmentation (PIH), atrophic scars (ASs), and a hypertrophic scar (HS) with induration were observed on the right neck. We diagnosed this as an acne vulgaris complication. HS lesions were topically treated by injecting triamcinolone acetonide, and the patient was prescribed 8.1 g/day of oral Saireito (Japanese herb). Adapalene benzoyl peroxide gel and topical tacrolimus hydrate ointment were used to treat PIE and TE. Both HSs and PIE improved;however, TE and AS did not improve. Currently, the patient is under observation. We consider this to be a very rare concurrent occurrence of diverse complications of acne vulgaris, and present the following case study. 展开更多

Hyperledger Fabric是一种国内外广泛使用的联盟链框架,在基于Fabric技术的一些业务中具有协同组织众多、交易操作频繁、事务冲突增加等特点。Fabric采用的多版本并发控制技术能够在一定程度上解决部分交易冲突,提升系统并发性,但其机制不完善,会出现部分交易数据无法正常上链存储的问题。为了实现海量交易数据完整、高效、可信的上链存储,提出一种基于Fabric预言机的数据上链预处理机制。设计海量数据冲突预处理(MCPP)方法,通过检测、监听、延时提交、事务加锁、重排序缓存等方式实现主键冲突交易数据的完整上链。引入数据传输保障措施,在传输过程中利用非对称加密技术防止恶意节点伪造认证信息,确保交易数据链外处理前后的一致性。通过理论分析和实验结果表明,该机制可有效解决联盟链平台中海量交易数据上链时的并发冲突问题,当交易数据规模达到1 000和10 000时,MCPP的时效性比LMLS提高了38%和21.4%,且成功率接近100%,具有高效性和安全性,同时在无并发冲突情况下不影响Fabric系统性能。 展开更多
