Hepato-pancreato-biliary diseases (HPBD) are often complicated. The diagnosis and treatment of HPBD involve many disciplines. The malignant degree of hepatobiliary pancreatic system is high, and the prognosis of patients is poor. The multidisciplinary team (MDT) brings specialists from different disciplines together to make a comprehensive and individualized treatment for patients. MDT is emerging in HPBD in recent years. MDT helps improve the accuracy of diagnosis and prognosis. However, there are still some controversies and obstacles in the application of MDT for patients with HPBD. We reviewed the development, current status and experience of MDT in the field of HPBD, analyze the current controversy and obstacles, and providing reference for its future application.

Objective·To investigate the predictive value of the Clinical Frailty Scale(CFS)in the long term outcomes in acute myocardial infarction(AMI)patients who completed in-hospital cardiac rehabilitation(CR).Methods·A total of 501 AMI patients treated in the Cardiology Center of Shanghai Sixth People's Hospital,Shanghai Jiao Tong University of Medicine from May 2020 to May 2022 were prospectively enrolled,with their baseline clinical data collected.The patients completed graded in-hospital CR and were assessed by CFS based on their completion of CR before discharge.Patients were then categorized into three groups(norm group,vulnerable group and frail group)according to their CFS level.The difference in 1-year major cardiovascular event(all-cause death and re-hospitalization for heart failure)rates among the three groups was investigated.Logistic regression analysis was performed to explore the effective risk factors relevant to the outcomes,and receiver operator characteristic(ROC)curves were generated to analyze the prognostic value.Finally,an optimal prediction model was developed.Results·The CFS level in AMI patients who completed CR was positively correlated with age and peak pro-B-type natriuretic peptide(peak proBNP),and inversely correlated with gender difference(P<0.05).Accompanied with the elevated CFS level,the incidence of both outcomes increased,and there were significant differences in all-cause death(2.6%,5.6%and 15.2%,P=0.002),and while no significant differences in re-hospitalization for heart failure among the three groups(19.6%,22.2%and 24.2%).All-cause death of the frail group was significantly higher than that of the norm group(P=0.004),while there was no significant difference between the vulnerable group and the norm group.CFS could sensitively predict the 1-year all-cause death in AMI patients(β=1.89,OR=6.61,P=0.001),and the risk model combined with CFS had the best predictive effect(AUC=0.845,P=0.000).Conclusion·Assessment by CFS in AMI patients who completed in-hospital CR contributes to identifying AMI patients with high risk of all-cause death in 1 year.

The Tibet Autonomous Region (hereinafter referred to as Tibet) is located on the border of the country, with a harsh natural environment and an average elevation of over 4 000 meters. Currently, the total permanent population of the region is about 3.65 million, distributed over 1.2 million square kilometers of land. The land is vast and sparsely populated, making it extremely difficult to allocate medical resources. The above objective reasons make it difficult for patients in Tibet to seek medical treatment in a timely manner, and there are multiple complications when seeking medical treatment. In terms of inguinal hernia disease, the proportion of patients with inguinal incarcerated hernia is relatively high. Due to poor medical conditions, patients have poor awareness of seeking medical treatment, and lack of understanding of the disease, leading to serious complications and even death caused by inguinal incarcerated hernia. With the releasing of clinical guidelines, advances in equipment and materials, and updates in treatment concepts and anatomical understanding, laparoscopic inguinal hernia repair has been vigorously promoted. The promotion of new medical technologies in Tibet is relatively lagging behind. In recent years, with the strong support of the China Hernia Society and the Chinese Hernia Collegen of Surgeons, minimally invasive treatment related to hernia disease has been promoted in Lhasa since 2016, especially for inguinal hernia. At present, minimally invasive technology for treating inguinal hernia has been widely promoted to tertiary hospitals in Tibet. Through publicity, patients can seek medical attention in a timely manner, significantly reducing the incidence of inguinal incarcerated hernia. Based on litera-tures and clinical practice, the authors explore the promotion, application, and historical significance of minimally invasive surgery for hernia in Tibet.

Objective To evaluate the economics of azacitidine versus decitabine in the treatment of myelodysplastic syndrome(MDS)from the perspective of health system in China,and provide references for clinical drug selection.Methods A Markov model was constructed based on the data of a multi-center retrospective cohort study(NCT01409070),with a model simulation time limit of 10 years and the cycle period of 28 days.The quality-adjusted life years(QALYs)was used as health output index and incremental cost-utility ratio(ICUR)was calculated to evaluate the economics of azacitidine versus decitabine in the treatment of MDS.One-way sensitivity analysis and probabilistic sensitivity analysis were adopted to examine the robustness of the model simulation results.Results The results of basic analysis showed that compared with decitabine group,the total cost of azacitidine group reduced by 281 185.46 yuan and the utility increased by 0.17 QALYs.Azacitidine therapeutic regimen was the absolute dominance plan.One-way sensitivity analysis showed that progression-free survival state utility value,discount rate and decitabine cost had greater influence on the results.The results of probabilistic sensitivity analysis suggested that azacinidine therapy was always economical within the willingness to pay threshold range of 3 times Chinese per capita gross domestic product in 2021.Conclusion From the perspective of health system in China,azacitidine has more cost-utility advantages than decitabine in the treatment of MDS.

Objective:To study the clinical efficacy of laparoscopic radical cholecystectomy in the treatment of stage Ⅲ gallbladder cancer.Methods:The clinical characteristics and postoperative follow-up data of 184 patients (male 66, and female 118) who underwent radical cholecystectomy for stage Ⅲ gallbladder cancer at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, from May 2015 to May 2022, were retrospectively analyzed. The age was (67.0±8.6) years old (range 38 to 85 years old). There were 71 patients in the laparoscopic group and 113 in the open group. The general medical data, surgery-related indicators and complications were analyzed. Follow-up was completed by outpatient visits and by telephone.Results:The laparoscopic group showed better postoperative alanine aminotransferase [67.5 (40.0, 138.5) vs. 104.0 (45.0, 252.2) U/L] and aspartate aminotransferase [41.5 (26.0, 71.2) vs. 53.0 (30.2, 153.5) U/L] recovery, higher albumin levels [32.05 (30.18, 35.20) vs. 30.50 (27.70, 33.50) g/L], earlier abdominal drainage tube removal [8.00(6.00, 10.25) vs. 10.00(6.00, 13.00)d], shorter hospital stay [10.00(8.00, 15.25) vs. 14.00(9.00, 19.00) d] and lower incidences of complications [(14.1%(10/71) vs. 31.9%(36/113)] when compared with the open group (all P<0.05). The 1 year (49.1% vs 61.0%), 2 years (24.0% vs. 28.5%), 3 years (16.0% vs. 14.5%) overall survival ( P=0.640), and the 3 years progression-free survival (18.3% vs. 15.0%, P=0.463) showed no significant difference between the 2 groups. Conclusion:Laparoscopic surgery for AJCC TNM stage Ⅲ gallbladder cancer showed comparable results with open surgery. When compared with open surgery, laparoscopic radical resection of gallbladder cancer had the advantages of earlier removal of abdominal drainage tube, lower incidence of postoperative complications, and shorter hospital stay.

Quantity is the key factor to ensure the safety and effectiveness of medicines. It is very important to study and determine the traditional measuring units and their quantity values of Tibetan medicine. Based on the literature records of Tibetan medicine and combined with modern experimental verification and investigation research, this study determined the reference, name, and conversion rate of traditional measuring units of Tibetan medicine. Meanwhile, through large sample sampling and repeated quantification of refe-rence of basic units, its weight and volume were clarified. The modern SI volume and weight unit values corresponding to the traditional volume and weight units of Tibetan medicine were deduced, and the correctness, reliability, and practicability of these determination results were demonstrated. This study also put forward some specific suggestions and reference values for formulating the standards of measuring units of weight and volume of Tibetan medicine. It is of great significance in guiding the processing, production, and clinical treatment of Tibetan medicine, and promoting the standardization and standardized development of Tibetan medicine.

Objective:To study the effect of preoperative transcatheter arterial chemoembolization (TACE) on postoperative complications after hepatectomy in patients with hepatocellular carcinoma (HCC) by propensity score matching analysis.Methods:Of 1 666 patients with HCC undergoing hepatectomy in Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology and Tianyou Hospital of Wuhan University of Science and Technology from March 2015 to March 2021 were retrospectively screened. Of 262 patients were enrolled, including 236 males and 26 females, aged (50.3±11.8) years. Of 131 patients were enrolled in both the single surgery group and the combined group (preoperative TACE + surgical resection). Factors affecting the complications after hepatectomy in patients with HCC were analyzed using univariate and multivariate logistic regression method.Results:After matching the propensity score, the incidence of postoperative complications in the single surgery group was 22.1% (29/131), lower than that in the combined group [41.2% (54/131), χ 2=11.02, P<0.001]. The incidence of bile leakage in the single surgery group [2.3% (3/131)] was also lower than that in the combined group [(9.2% (12/131), χ 2=5.73, P=0.017]. Multivariate logistic regression analysis showed that the combined group ( OR=2.43, 95% CI: 1.28-4.61, P=0.007) had an increased incidence of postoperative complications, so did patients with a preoperative alpha-fetoprotein > 400 μg/L, anatomic hepatectomy, long operation time, and hilar occlusion. Conclusion:Preoperative TACE could be a risk factor for postoperative complications in patients with HCC, especially for the postoperative biliary leakage.
