Objective To design a hemostatic clip and evaluate its efficacy and success rate of closure of stomach wall defect after full thickness resection (FTR).Methods A full thickness circular or linear resection (3 to 5 cm) was made on each model's antrum with needle knife and insulated-tip knife.The specimens were divided into 2 groups, using either an interrupted or continuous suturing method.Then the closure condition, suturing time, number of clips required and success rate of closure were compared.Results All 12 defects were successfully closed.The average closing time of interrupted and continuous suturing group were 13.33 ± 1.09 and 10.17 ±2.11 minutes, and the mean number of clips used were 4.67 ± 0.82 and 2.67 ± 0.82.The success rate was 100％.Conclusion This newly designed clip is a fast, reliable and convenient tool for stomach wall defect closure after FTR.

Objective To explore a scientific and reasonable fiscal input mechanism for public hospitals, in order to fully leverage the policy guidance and efficiency of such funding.Methods With literature review, expert consultation and demonstration, a basic subsidy model for public hospitals was established.According to the past operation data of 4 public hospitals in Baoshan district of Shanghai, the study figured out specific subsidy standards.Results The basic subsidy for public hospitals should be determined according to the number of approved beds, the number of outpatients and emergency visits, hospital bed days, surgeries, key services, and the quality and efficiency of work.In Baoshan district, the standard reference value of subsidy for each approved bed, each outpatient and emergency visit, each bed-day, each surgical operation is 42 096 yuan, 27.9 yuan, 104.9 yuan and 244 yuan respectively.The standard value of subsidy is 100 yuan per bed for critically ill inpatients.For patients under clinical pathway management, the subsidy is 300 yuan per case, and for hospital maternal care, it is 150 yuan per person.Conclusions The basic subsidy model for public hospitals has overcome the shortcomings of fiscal input based on hospital scale or hospital workload, and established an incentive mechanism to promote the implementation of key services.These measures can improve the operation mechanism of public hospitals and encourage them to play their role of public welfare as designed.

Objective To evaluate the safety and effectiveness of a new hemostatic clip with sutures for ESD suspension method in animal models.Methods A total of 20 porcine stomachs were randomly divided into the experimental group (n=10) and the control group (n=10).ESD was done respectively in antrum greater curvature and antrum back wall of porcine stomach in vitro.All procedures were completed by the same endoscopist and nurse.The incidence of perforation,mucosa diameter,total operation time (T),dissection time (T1),the average number of submucosal injection,and one-time complete dissection rate were compared between two groups.Results Procedures were done successfully in antrum of 40 poccine in vitro and all mucosa were dissected completely in one procedure.No perforation occurred.Compared with the control group,the mucosa diameter difference was not statistically significant (P =0.368).The total operating time [(34.70± 1.06) min VS (37.1 0± 2.23) min,P =0.009],dissection time [(31.40± 2.00) min VS (34.80± 2.20) min,P=0.817] and the average number of submucosal injection[(7.60± 1.00) VS (10.60± 1.00),P＜0.001] in antral greater curvature ESD of the experimental group were significantly less than those of the control group.As for the antrum back wall,the mucosa diameter difference was not statistically significant.The total operation time [(37.00± 1.25) min VS (39.60± 1.65) min,P＜0.001],dissection time[(34.50± 1.35) min VS (37.00± 1.25) min,P＜0.001],the average number of submucosal injection [(7.60± 1.27) VS (11.40± 1.00),P＜0.001] were also significantly less than those of the control.Conclusion The new hemostatic clip with sutures for suspension can significantly shorten the operation time,reduce the number of submucosal injections and the difficulty in ESD.

AIM: To evaluate the safety and tolerance of ibandronate in Chinese healthy volunteers. METHODS: The trial protocol was designed according to the Good Clinical Practice(GCP). After physical examination and laboratory tests were performed, 36 healthy volunteers were divided randomly into 6 dose groups, including 1 mg , 2 mg , 3 mg , 4 mg , 5 mg and 6 mg , with 6 subjects in each group(3 male and 3 female). Clinical symptoms, vital signs, routine blood tests, routine urine tests, hepatic function, renal function, blood electrolytes, electrocardiogram, and electroencephalogram were observed or examined before and after a single intravenous infusion of ibandronate. RESULTS: After single intravenous infusion doses of 1- 6 mg , the vital signs, clinical symptoms and laboratory tests were all in the normal range, but there were some slight ADRs concerned with the drug, such as hypophosphataemia, increased body temperature, perspiring,pain of bone or muscle and hypocalcaemia. But the ADRs were found vanishing in one or two weeks. CONCLUSION: Single intravenous infusion (up to 6 mg ) of domestic ibandronate in 36 chinese healthy volunteers is safe and tolerable.

Model informed precision dosing (MIPD) is a new concept to guide precision dosing for individual patient by modeling and simulation based on the available information about the individual patient, medications and the disease. Compared to the empirical dosing, MIPD could improve the efficacy, safety, economics and adherence of the pharmacotherapy according to the individual's pathophysiology, genotyping and disease progression. This consensus report provides a brief account of the concept, methodology and implementation of MIPD as well as clinical decision supporting systems for MIPD. The status and future advancing of MIPD was also discussed to facilitate the appropriate application and development of MIPD in China.

Objective:To explore forecast indicators for the prognosis of sepsis in adult extremely severe burn patients.Methods:Case data of adults with extremely severe burns combined with sepsis admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine from January 2017 to December 2021 were retrospectively collected. According to the prognosis, all patients were divided into a death group and a survival group. The general conditions of the two groups were compared. The clinical symptoms, vital signs, platelet count (PLT), white blood cell count (WBC), neutrophil ratio, procalcitonin (PCT), blood sodium, blood glucose, hemoglobin and albumin levels at diagnosis of sepsis were also compared between the two groups. The independent sample t test, Mann?Whitney U test, or Fisher's exact probability test was used for group comparison. Variables with statistical significance in univariate analysis were included in the Cox regression model for multivariate analysis to assess the effect of each index on the outcome of extremely severe burn patients with sepsis. The predictive value of each index for sepsis outcome was analyzed by the receiver operating characteristic curve (ROC). Results:A total of 60 patients with particularly severe burn sepsis were selected, including 41 males and 19 females aged 18 to 84 years. The diagnosis time of sepsis was 14 (7, 24) days after injury. There were 29 patients in the death group and 31 patients in the survival group, and the mortality rate was 48.3%. Compared with the survival group, PLT and hemoglobin levels in the death group decreased significantly (both P<0.05), and PCT and blood sodium levels increased significantly (both P<0.05), while the other indicators did not change significantly (all P>0.05). The results of multivariate Cox regression analysis showed that hemoglobin ( HR=0.936, 95% CI: 0.935-0.991) and serum sodium levels ( HR=1.031, 95% CI: 1.010-1.052) at the time of sepsis diagnosis were independent risk factors affecting the prognosis of sepsis in extra-severe burn patients (both P<0.05). ROC curve analysis showed that the AUCs of hemoglobin, blood sodium and PCT for predicting the prognosis of extremely severe burn patients with sepsis were 0.747, 0.811 and 0.690, respectively (all P<0.05). The cut-off value of hemoglobin for predicting prognosis was 77 g/L, with a sensitivity of 69.0% and specificity of 74.2%. The cut-off value of blood sodium for predicting prognosis was 138 mmol/L, with a sensitivity of 89.7% and specificity of 61.3%. The cut-off value of PCT was 3.51 μg/L, with a sensitivity of 65.5% and specificity of 74.2%. Conclusions:Hemoglobin, blood sodium and PCT may be predictors of outcome in extremely severe burn patients with sepsis.
