ObjectiveTo evaluate the efficacy and safety of first-line transcatheter arterial chemoembolization （TACE） combined with targeted therapy and immunotherapy in the treatment of patients with stage Ⅱb/Ⅲa hepatocellular carcinoma （HCC） based on China Liver Cancer Staging （CNLC）. MethodsA total of 198 patients who received first-line TACE combined with targeted therapy and immunotherapy or received TACE alone from January 2015 to December 2022 in the First Affiliated Hospital of Soochow University were enrolled in this study， and after propensity score matching， there were 50 patients in combination group and 50 patients in TACE group. The Kaplan-Meier method was used to calculate median overall survival （mOS） and median progression-free survival （mPFS）. Modified Response Evaluation Criteria in Solid Tumors was used to evaluate objective response rate （ORR） and disease control rate （DCR）， and Common Terminology Criteria for Adverse Events v5.0 was used to evaluate adverse events. The chi-square test was used for comparison of categorical data between two groups； the t-test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used to estimate survival time and calculate 95% confidence interval （CI）， and the Log-rank test was used for comparison of mOS and mPFS between two groups. ResultsThe combination group had an mOS of 30.1 months （95%CI： 21.9‍ ‍—‍ ‍38.3）， and the TACE group had an mOS of 14.5 months （95%CI： 11.0 ‍—‍‍ ‍18.0）， with a significant difference between the two groups （χ²=17.8， P<0.001）； the combination group had an mPFS of 10.3 months （95%CI： 8.8‍ ‍—‍ ‍11.8）， and the TACE group had an mPFS of 7.1 months （95%CI： 5.8‍ — ‍8.4）， with a significant difference between the two groups （χ²=10.4， P<0.001）. There were significant differences between the combination group and the TACE group in ORR （84% vs 58%， P<0.05） and DCR （94% vs 80%， P<0.05）. There was no significant difference between the combination group and the TACE group in the incidence rate of adverse events （24% vs 16%， P=0.317）， and no adverse event-related deaths were observed in either group. ConclusionCompared with TACE alone， TACE combined with targeted therapy and immunotherapy has a better efficacy in the treatment of patients with CNLC stage Ⅱb/Ⅲa HCC， without increasing the incidence rate of severe adverse events.

ObjectiveTo investigate the influencing factors for the clinical outcome of patients with drug-induced liver injury （DILI）， and to establish a nomogram prediction model for validation. MethodsA retrospective analysis was performed for the general information and laboratory data of 188 patients with DILI who were admitted to Heilongjiang Provincial Hospital Affiliated to Harbin Institute of Technology from January 2017 to December 2022， and according to their clinical outcome， they were divided into good outcome group with 146 patients and poor outcome group with 42 patients. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between two groups. Univariate and multivariate Logistic regression analyses were used to investigate the independent influencing factors for the clinical outcome of DILI patients. R Studio 4.1.2 software was used to establish a nomogram model， and calibration curve， receiver operating characteristic （ROC） curve， and decision curve analysis （DCA） were used to perform internal validation. ResultsThe univariate Logistic regression analysis showed that liver biopsy for the diagnosis of DILI， platelet count， cholinesterase， albumin， prothrombin time activity， IgM， and IgG were associated with adverse outcomes in patients with DILI. The multivariate Logistic regression analysis showed that liver biopsy for the diagnosis of DILI （odds ratio ［OR］=0.072， 95% confidence interval ［CI］： 0.022‍ ‍—‍ ‍0.213， P<0.001）， clinical classification （OR=0.463， 95%CI： 0.213‍ ‍—‍ ‍0.926， P=0.039）， alanine aminotransferase （OR=0.999， 95%CI： 0.998‍ ‍—‍ ‍1.000， P=0.025）， prothrombin time activity （OR=0.973， 95%CI： 0.952‍ ‍—‍ ‍0.993， P=0.011）， and IgM （OR=1.456， 95%CI： 1.082‍ ‍—‍ ‍2.021， P=0.015） were independent influencing factors for clinical outcome in patients with DILI. The nomogram prediction model was established， and after validation， the calibration curve was close to the reference curve. The area under the ROC curve was 0.829， and the DCA curve showed that the model had good net clinical benefit. ConclusionThe nomogram prediction model established in this study has good clinical calibration， discriminative ability， and application value in evaluating the clinical outcome of patients with DILI.

Objective Explore the impact of long-term blood glucose fluctuations and blood glucose control on the stroke incidence in patients with type 2 diabetes mellitus(T2DM).Methods An observa-tional cohort of patients with T2DM was established based on"Shanghai Community Chronic Disease Health Management Service Objects"on October 1st,2018.Follow-ups were conducted every three months,and fasting blood glucose(FBG)were tested at each visit.Basic epidemiological data were collected via the Shanghai Community Health Management Information Platform or survey questionnaires,and stroke incidents were gathered via the"Shanghai Cardio-Cerebrovascular Event Monitoring System".The first reported stroke incident within the observation period was considered.The observational deadline was December 31st,2021.Standard deviation of FBG was used to evaluate blood glucose fluctuation and FBG control rate was used to reflect blood glucose control status.Cox Proportional Hazards Model was utilized to analyze the impacts.Results The cumulative observation time was 91,826.1 person-years for the study,in which there were 1785 cases of stroke events observed,implying a cumulative incidence of 5.73%and incidence rate of 1943.9/100000 person-years.The mean number of follow-ups(10.29±3.07)per patient was recorded.The details of the stroke cases were as follows:transient ischemic attacks(n=111,6.22%),non-lacunar brain infarctions(n=754,42.24%),lacunar brain infarctions(n=798,44.71%),intracerebral hemorrhages(n=80,4.48%),non-intracerebral hemorrhages(n=8,0.45%),subarachnoid hemorrhages(n=12,0.67%),and unclassified strokes(n=22,1.23%).After excluding subjects with less than five follow-ups,the Cox Proportional Hazards Model suggested that increased standard deviation of FBG was an independent risk factor for the first stroke incident,and an increased blood glucose control rate was an independent protective factor.Both the standard deviation of FBG and the blood glucose control rate were not correlated with stroke recurrence.Conclusion Long-term blood glucose fluctuations and blood glucose control can predict the risk of a first stroke in patients with T2DM.The relationship between blood glucose fluctuations,blood glucose management,and stroke recurrence requires further studies.

Objective:To analyze the effect of thoracoscopic subsegmental resection under the guidance of three dimensional(3D)computed tomography bronchography and angiography(3D-CTBA)for resection of pulmonary nodules.Methods:A total of 40 patients who underwent 3D-CTBA-guided thoracoscopic subsegmental resection in Nanjing Jiangbei Hospital of Nantong University from January 2020 to October 2021 were selected as the observation group,and other 35 patients who underwent 3D-CTBA-guided thoracoscopic pulmonary segmentectomy were selected as the control group.The intraoperative and postoperative conditions,and the incidence of postoperative complications of the two groups were observed.Results:The differences of amount of intraoperative blood loss,average margin width,postoperative drainage,retention time of drainage tube between observation group and control group were significant(t=8.644,2.862,10.03,3.277,P<0.05),respectively.The numbers of occurring postoperative chest leakage,pulmonary infection and hemoptysis in observation group and control group were respectively"3,1,1"and"2,1,2".The incidences of complications of two groups were respectively 12.5%and 14.29%,without statistical significance between the two groups(P>0.05).Conclusion:3D-CTBA-guided thoracoscopic subsegmental resection can shorten the operation time,and reduce intraoperative blood loss and the injury of tracheas and blood vessels,and improve the postoperative recovery of patients.

Objective:This study aimed to explore the status of radiological Kashin-Beck disease (KBD) among school-aged children in Chamdo City, Tibet, through a 3-year monitoring survey, providing epidemiological evidence for prevention and control strategies.Methods:The target areas for this study were Luolong, Bianba, and Basu counties in Chamdo City, Tibet Autonomous Region, identified as having the most severe historical cases of KBD. Children aged 7-12 years attending school were enrolled as study subjects. Anteroposterior X-ray films of the right-hand were taken, and radiological diagnoses were made based on the "Diagnosis of Kashin-Beck Disease" criteria (WS/T 207-2010). Two experienced researchers independently reviewed the X-rays, and intra- and inter-group consistency were assessed using weighted Kappa values and percentage agreement. Cross-sectional surveys were conducted in 2017 and 2020 to describe the X-ray detection rates of KBD, and logistic regression analysis was employed to construct a predictive model of risk factors for radiological KBD cases.Results:In 2017, a total of 5,711 children aged 7-12 years in Chamdo City, Tibet, participated in the baseline cross-sectional survey (average age 9.2 years, 48.0% female), with 28 cases of radiological KBD. The age- and gender-standardized prevalence rate was 0.527%. In 2020, 6,771 participants (average age 9.3 years, 49.5% female) underwent a second cross-sectional survey, with 9 cases of radiological KBD and a standardized prevalence rate of 0.134%. Logistic regression analysis indicated that older age [ OR=2.439, 95% CI(1.299, 4.580), P=0.006] and female gender [ OR=8.157, 95% CI(1.016, 65.528), P=0.048] were independent risk factors for radiological KBD cases. Conversely, higher residential altitude, under the premise of Tibet's high altitude, was a protective factor [ OR=0.995, 95% CI(0.990, 0.999), P=0.032). Conclusion:The radiographically positive detection rate of KBD among school-aged children in Chamdo City, Tibet Autonomous Region, is at an extremely low level and showing a declining trend, reaching the historical standard in 2020. Considering the absence of positive signs in affected children, it suggests that local KBD has been effectively eliminated.

Objective To explore the best neoadjuvant treatment strategy for esophageal cancer and provide a theoretical basis for clinical formulation of neoadjuvant treatment plan. Methods PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, Wanfang, and VIP were searched from inception to May 2022. Two researchers independently performed literature screening and data extraction. The quality of the studies was evaluated by the Cochrane risk of bias tool, and data analysis was performed in RStudio environment using R3.6.3 software. Results A total of 24 studies were included, covering 5 286 patients treated with surgery alone, neoadjuvant chemotherapy (NCT), neoadjuvant radiotherapy (NRT), or neoadjuvant chemoradiotherapy (NCRT) followed by combined surgical treatment. The risk of bias of the studies was low. The results of the network meta-analysis showed that combined surgical treatments after NCRT [HR=0.77, 95%CI (0.70, 0.85)] and NCT [HR=0.89, 95%CI (0.81, 0.98)] were effective methods to improve patients' overall survival (OS) compared with surgery alone. In addition, NCRT could significantly reduce the incidence of local recurrence [OR=0.43, 95%CI (0.30, 0.58)] and distant metastasis [OR=0.71, 95%CI (0.52, 0.93)] in patients with esophageal cancer. However, NCRT [RR=1.30, 95%CI (0.77, 2.20)] increased the mortality rate of patients at 30 d after surgery. Conclusion The available evidence suggests that NCRT combined with surgery is the best option for treating patients with resectable esophageal cancer, but this treatment carries the risk of increased 30 d postoperative mortality. Future studies should focus on optimizing the NCRT regimen with the aim of improving patients’ OS while effectively reducing postoperative mortality. In addition, more high-quality randomized controlled trials are needed to support the results of the study.

Objective    To analyze a new classification of the left apicoposterior segmental bronchus and summarize its clinical significance. Methods     We accessed the computed tomography imaging data of the inpatients treated in the Department of Thoracic Surgery, Henan Provincial People's Hospital between January and November 2021. We observed and classified the branching pattern of the left apicoposterior segmental bronchus (B1+2) using three-dimensional computed tomography bronchography and angiography (3D-CTBA) technique. And we filtered out the patients who underwent thoracoscopic left apicoposterior segmentectomy and analyzed their clinical data retrospectively to summarize the instructing significance of different bronchial classification in the accurate and safe operation of left apicoposterior segmentectomy. Results     Finally 240 patients were collected, including 131 males and 109 females with a median age of 51.0 (19.0-77.0) years. The anatomical pattern of the left apicoposterior segmental bronchus was divided into four main types based on the branching pattern of the outer subsegmental bronchi (B1+2c): type Ⅰ 10% (24 patients), type Ⅱ 54% (130 patients) , type Ⅲ 17% (40 patients) , type Ⅳ 18% (43 patients) and other variations 1% (3 patients). Thirty-two patients smoothly underwent thoracoscopic left apicoposterior segmentectomy, including 23 patients of type Ⅰ and type Ⅱ receiving LS1+2 resection, the other 9 patients of type Ⅲ and type Ⅳ receiving LS1+2 resection (3 patients), LS1+2c resection (4 patients) and LS1+2(a+b) resection (2 patients). Conclusion     This new classification systematically and concisely elucidates the branching characteristics of the left apicoposterior bronchus. Different branching types are instructive to the left apicoposterior segmentectomy.
