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 summarize the repair experience and clinical characteristics of cleft lip and palate in Tibet.Methods:From August 2020 to August 2021, patients with cleft lip and palate treated during the period of corresponding author aid to Tibet were included. The American Association of Anesthesiologists (ASA) was used to assess the anesthesia risk before operation. For the cleft lip repair, Millard rotation advancement technique and reconstruction of nasal-labial muscle tension lines group were used. Modified Von Langenbeck technique was adopted for cleft palate repair. The amount of blood loss and short-term postoperative complications such as hematoma, infection, wound dehiscence, flap circulation disorder and palatal fistula were counted. The Likert five-point scale was used to evaluate the surgical satisfaction of patients with cleft lip and the audiometric evaluation method was used to assess the improvement of cleft palate speech. The data were statistically analyzed by SPSS 20.0 software. The measurement data were expressed by Mean±SD. P<0.05 was considered statistically significant. Results:A total of 46 patients were included, including 26 males and 20 females, aged from 2 to 57 years, with a median of 32 years. There were 36 patients with cleft lip or secondary deformities after cleft lip surgery and 10 patients with cleft palate. Among the 46 cases, ASA Ⅰ was 39, and ASA Ⅱ, ASA Ⅲ were 5 and 2, respectively. There were 5 patients with congenital heart disease, including 2 cases of patent ductus arteriosus and 3 cases of patent foramen ovale. Pulmonary hypertension was found in 8 cases. The average blood loss during the repair of cleft lip and cleft palate was 30 ml and 50 ml, respectively. No postoperative complications such as hematoma, infection, wound dehiscence and palatal fistula occurred. The patients were followed up for 6 to 24 weeks, with an average of 8 weeks. The crista philtra point on the affected side of the patients with cleft lip was fully lowered and was basically symmetrical with the healthy side. The bilateral nostril symmetry was significantly improved compared with that before surgery, and the nasal columella was in the middle. The cleft palate was all closed and the mobility of soft palate was improved. All patients were satisfied with the surgical results, with an average satisfaction score of 4.5. The mean preoperative speech score of patients undergoing cleft palate repair was 1.4 ± 0.5 and the postoperative was 4.3 ± 0.5 ( t=16.16, P<0.001). Conclusion:Compared with the plain area, patients with cleft lip and palate in Tibet have the characteristics such as delayed treatment, the complex of deformity and often combined with other congenital organ malformation. In order to get good result and higher satisfaction rate, it is recommended to use classical surgical technique for the above deformity repair. It is also important to carefully evaluate the risk of general anesthesia.

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 explore the clinical effect of Kirschner wire intramedullary fixation in the treatment of both-bone forearm fractures in children of high altitude area. METHODS: From August 2020 to December 2021, 19 children were treated with Kirschner wire intramedullary fixation including 11 males and 8 females, aged from 4 to 13 years old with an average of (8.16±2.71) years old. The course of disease was 1 to 10 days, with a mean of (4.11±2.51) d. First, close reduction was performed. If the reduction was unsuccessful, limited open reduction was performed, followed by Kirschner wire intramedullary fixation of the radius and ulna. The fracture healing was evaluated by X-ray after operation, and the curative effect was evaluated by Anderson forearm function score standard. RESULTS: The wound healed well after operation, 2 cases had clinical manifestations of needle tail irritation after operation, and the symptoms disappeared after removing the internal fixation. The average follow-up time was(7.68±3.50) months (3 to 14 months). X-ray showed that all fracture healing in follow-up, Anderson forearm function score showed excellent in 16 cases, good in 2 cases and fair in 1 case at the final follow-up. CONCLUSION Children with fractures in plateau areas often have delayed medical treatment, lack of medical conditions and insufficient compliance. Based on these characteristics, Kirschner wire intramedullary fixation for the treatment of children's double forearm fractures has the advantages of small injury and rapid recovery. It is a kind of operation method that can be popularized.
