Objective:To evaluate the efficacy of combined cricopharyngeal myotomy (CPM) and autologous fat injection laryngoplasty (AFIL) in the management of dysphagia secondary to glossopharyngeal and vagal nerve injury.Methods:This retrospective cohort study collected the clinical data of 18 patients with persistent dysphagia due to glossopharyngeal and vagus nerve injuries, who underwent concurrent cricopharyngeal myotomy (CPM) and autologous fat injection laryngoplasty (AFIL) at the Department of Otolaryngology, Peking Union Medical College Hospital, from January 2017 to December 2024. Pre-and postoperative assessments included electronic flexible laryngoscope, the Chinese version of Swallow Quality-of-Life Questionnaire (CSWAL-QOL), videofluoroscopic swallowing study (VFSS), body weight changes, and nasogastric tube (NGT) removal status with routine follow-up. The comparison of swallowing function before and after surgery was conducted using paired samples t-test and χ2 test. Results:The study cohort comprised 10 male and 8 female patients, with ages ranging from 33 to 70 years (mean±SD: 53.8±10.5). All surgical procedures were completed successfully without complications. During the 6-to 24-month follow-up period, 10 of the 13 patients who were initially nasogastric tube-dependent achieved successful decannulation. Compared with preoperative values, postoperative measurements demonstrated statistically significant improvements across all parameters: mean body weight increased from (56.95±9.14) kg to (59.22±8.72) kg ( t=3.689 , P<0.01), CSWAL-QOL scores improved from 91.89±17.81 to 130.83±25.42 ( t=6.921 , P<0.01), while, both VFSS scales showed marked reductions (VFSS-SWAL: 6.78±1.40 to 3.39±1.61, t=-8.001, P<0.01; PAS: 6.56±1.15 to 2.94±1.26, t=-10.114, P<0.01). Conclusions:Combined CPM and AFIL represents an effective surgical approach for dysphagia following glossopharyngeal and vagal nerve injury, thereby demonstrating significant improvements in both swallowing function and quality of life.

Objective:To explore the safety of laparoscopic modified transcystic biliary drainage(modified C-tube technique)in the treatment of biliary stones and application of diagnosing biliary disease.Methods:A retrospective analysis was conducted on the clinical data of 68 cases of biliary stones successfully treated with laparoscopic modified C-tube technique from August 2021 to December 2023.The safety,effectiveness,and area of applications were analyzed.The reliability of the principle of the modified fixation method was verified by using an ex vivo gallbladder.Results:Three cases of ex vivo gallbladder demonstrated that the strength of the modified fixation method was reliable,and the sinus tract formed by suture after immediate extraction of the C tube could be dislocated and closed,resisting the bile outflow caused by the weight of the gallbladder.Among the 68 patients,42 were difficult biliary stones,6 were suspected common bile duct stones,and 5 were extrahepatic bile duct stones combined with intrahepatic bile duct stones.Among them,48 cases underwent choledochoscopy assisted trans-choledochal approach for stone removal,and 10 cases underwent transcystic approach stone removal,Six patients underwent simply basket exploration and removal of stones through the cystic duct(5 patients had no residual stones on postoperative C-tube angiography,1 patient had suspected residual stones,and the patient refused further examination and treatment for no symptom),and 4 patients only underwent biliary drainage through the cystic duct;two patients with retained stone passed after the use of topical nitrate drip infusion via C-tube,seven cases underwent endoscopic retrograde cholangiopancreatography(ERCP),stone removal with the assistance of a C-tube after laparoscopic surgery,and the results were uneventful.The mean surgical time was(131±44)min(76-279 min),the maximum daily drainage volume of the C-tube was(401±235)mL/d(10-1 150 mL/d),the hospital stay was(8.6±3.6)d(2-19 d),and the mean time of C-tube removal was(11±6.9)d(5-46 d).There were 14 overall complications,including 2 residual stones,and 12 C-tube related complications,comprising of 1 gradeⅢ a,2 grade Ⅱ,and 9 grade Ⅰ.There were 9 cases of C-tube related adverse events that did not cause complications,including 3 of early detachment,2 of displacement,and 4 of deep insertion.The median follow-up time after surgery was 21(2-30)months,and 5 patients had recurrent stones.Among them,4 patients had slow contrast outflow during cholangiogram,and 1 patient had obvious pancreaticobiliary reflux.55 patients underwent C-tube amylase measurement,and 9 cases showed a significant increase in bile amylase(349-44 936 U/L),suggesting the presence of pancreaticobiliary reflux.Conclusion:Laparoscopic modified C-tube technique can be effectively used in the treatment of biliary stones,which is relatively safe and can be attempted in the diagnosis of biliary diseases.

Objective:To explore the material basis and potential mechanism of Sanhuang Yishen Capsules in the treatment of diabetes through network pharmacology, molecular docking and experimental verification.Methods:The active components and targets of Sanhuang Yishhen Capsules were screened using China Natural product chemical composition database and SymMap database, and the related targets of T2DM were screened by GeneCards database. The "Chinese materia medica-active component-target" network was constructed, and the intersection genes were enriched by GO and KEGG using R language. Key active components were selected for molecular docking verification with potential core targets. 60 rats were divided into normal group, model group, and Sanhuang Yishen Capsules group according to random number table method, with 15 rats in each group. In addition to the normal group, the diabetic rat model was prepared in the other groups, and the corresponding drugs were intragastric in each group for 8 weeks. The levels of fasting blood glucose (FBG), fasting insulin (FINS) and insulin resistance index (HOMA-IR) were measured by radioimmunoassay. Western blotting was used to detect protein expressions of epidermal growth factor receptor (EGFR), epidermal growth factor (EGF), Akt serine/threonine kinase 1 (AKT1), recombinant tumor protein p53 (TP53), and recombinant caspase 3 (CASP3).Results:A total of 160 active components and 298 targets of Sanhuang Yishen Capsules, 2194 targets related to T2DM, and 166 intersection targets were obtained. GO and KEGG analyzed a series of biological reaction processes mainly involved in signal transduction, oxidative stress, apoptosis, etc., and mainly involved in the regulation of P13K/Akt, P53, CASP3 and other targets. The results of molecular docking showed that the main active components obtained by screening had strong binding with the target. Compared with model group, FBG, FINS, HOMA-IR, TP53 and CASP3 in Sanhuang Yishen Capsules group decreased ( P<0.05), EGFR, EGF and Akt1 proteins increased ( P<0.05). Conclusion:The mechanism of Sanhuang Yishen Capsules for the treatment of may be related to the regulation of EGF/EGFR/P13K/Akt signaling pathway, TP53 signaling pathway, CASP3 signaling pathway, PPARG signaling pathway, ESR1 signaling pathway, PTGS2 signaling pathway, CAT signaling pathway and CTNNB1 signaling pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Digestive tract tumors are currently one of the most common types of cancer,including esophageal cancer,gastric cancer,hepatocellular carcinoma,pancreatic cancer,and colorectal cancer.Their prognoses are poor and the treatments require further improvement.Caveolin-1(CAV1)has a dual regulatory effect on digestive tract tumors as a tumor suppressor and cancer promoter.CAV 1 plays a major role in cell proliferation,invasion,metastasis,angiogenesis,and drug tolerance of digestive tract tumors.The regulation of CAV1 protein and its related signaling pathways may be a strategy for the treatment of digestive tract tumors.This review analyzes the relationship between CAV 1 and digestive tract tumors in terms of structure,function,expression regulation,regulation of epithelial-mesenchymal transition,and drug resistance in digestive tract tumors to provide new ideas for the diagnosis and treatment of digestive tract tumors.
