Objective To study the chronic toxicity and its severity of a Chinese medicine, Anshen Bunao Liquid ( ABL) , in rats, provide the target organs and extent of reversibility of their adverse effects, determine its non-toxic dose, and to evaluate the safety of medication and provide reference for clinical trial dose and observation indexes.Methods Two hundred and forty healthy 6-week old Wistar rats ( male:female=1:1) were divided into low,middle, and high dose Anshen Bunao liquid groups (2.5, 5, 10 mL/kg),and solvent control group (distilled water 2 mL/100 g), with 60 rats in each group.The drug was orally administered to rats once a day and 6 days per week for 26 weeks.The general state, body mass and food intake were measured.By the end of 13 weeks, 26 weeks of experiment and 4-week recovery period after drug withdrawal, hematological and biochemical indexes were assayed, organ coefficients were determined, and histopathological observation was performed.Results Long-term continuous oral administration of Anshen Bunao liquid, the general state, behavior and gross appearance showed no significant abnormal changes.Compared with the control group, no significant differences in all checked items were found in the treatment groups.During 3 and 6 months, the size and location of organs,organ weight and organ coefficient had no obvious changes, with only non-significant increase of weight of some organs.All the organ coefficients of the animals in different groups were within normal range.Histopathology showed no obvious patho-logical and toxicological changes even in the high-dose drug treatment group, and no delayed toxicity occurred after with-drawal of drug administration.Conclusions The Chinese drug, Anshen Bunao liquid has no obvious toxicity and no de-layed toxicity after withdrawal of the drug in rats.It is expected that the planned dose in clinical use is a safe dose.

Purpose:
Our study aimed to make a propensity score matching (PSM) analysis on the clinical application of gastricjejunum pouch anastomosis (GJPA) and Billroth-II anastomosis after distal gastrectomy.
Methods:
We collected clinical data from 249 patients who received distal gastrectomy from January 2016 to July 2020. According to the reconstruction method used, all patients were divided into the Billroth-II group and the GJPA group. Clinical data and operation complications were analyzed.
Results:
The clinical characteristics of the 2 groups were comparable after PSM. In the Billroth-II group, the incidence rate of delayed gastric emptying was higher than that in the GJPA group. Fewer patients suffered reflux gastritis in the GJPA group. The RGB (residue, gastritis, and bile) scores related to the severity of bile reflux into the remnant stomach, gastritis, and residue were higher in the Billroth-II group. Postoperative nutritional status and Visick classification demonstrated that postoperative subjective feelings in the GJPA group were improved significantly.
Conclusion
The application of GJPA in reconstruction after distal gastrectomy is safe, economical, and reliable. This reconstruction improved the quality of life of patients. It is worth popularizing widely in clinical settings.

Purpose:
Neoadjuvant chemotherapy is strongly recommended for advanced gastric cancer due to good local control and a high rate of R0 dissection with this strategy. Minimally invasive techniques such as laparoscopy-assisted or total laparoscopic approaches is becoming more and more acceptable in the treatment for gastric cancer. However, the safety and efficiency of total laparoscopic D2 gastrectomy (TLG) for advanced gastric cancer after neoadjuvant chemotherapy have not been well evaluated.
Methods:
A retrospective study in a single center from 2014 to 2016 was conducted. A total of 65 locally advanced gastric cancers were treated by laparoscopy-assisted gastrectomy (LAG) or TLG. Parameters which include operation time, blood loss, complications, hospital stay, 3-year overall survival, and 3-year disease-free survival were used for comparison.
Results:
The time of operation in the TLG group was shorter than in the LAG group (P = 0.013), blood loss was less (P = 0.002) and time to first flatus was shorter (P = 0.039) in the TLG group than that in the LLG group. Intraoperative and postoperative complications were comparable in both groups. No significant difference was found in 3-year overall and disease-free survival.
Conclusion
For patients with locally advanced gastric cancer after neoadjuvant chemotherapy, laparoscopic D2 gastrectomy can be considered as a safe and efficient alternative. A further multicenter prospective randomized controlled study is needed to elucidate the applicability of this technique for advanced gastric cancer.

OBJECTIVETo compare the clinical efficacy of the lymph node dissection patterns of the reverse and the traditional cabbage in hand-assisted laparoscopic D2 radical gastrectomy (HALG).
METHODSFrom December 2010 to October 2013, 194 patients with HALG in Chengdu Military General Hospital were enrolled in this study. According to the pattern of lymph node dissection, 108 patients were performed with the reverse procedure which took spleen as starting point, from left to right, and 86 patients were performed with the traditional cabbage procedure which took the abdominal cavity as the center, from both sides to middle. A retrospective comparative analysis was made on the intra- and post-operative data between the two groups.
RESULTSAll the patients were successfully performed with HALG, and no peri-operative death occurred. There were no significant differences in the incision length [(7.0 ± 0.2) cm vs. (6.9 ± 0.3) cm], the operative time [(170.9 ± 33.8) minute vs. (174.6 ± 22.4) minute], dissected lymph node number (17.6 ± 7.5 vs. 17.1 ± 5.8) and post-operative complications [(6.5%(7/108) vs. 8.1%(7/86)] between the reverse group and cabbage group (all P>0.05). However, less blood loss [(204.6 ± 98.2) ml vs. (259.1 ± 122.6) ml, P<0.01] and shorter postoperative hospital stay [(9.0 ± 1.7) day vs. (10.5 ± 4.0) day, P<0.01] were observed in reverse group as compared to cabbage group. During 1 to 6 months follow-up, no death case was found in reverse group, while 1 case died due to upper gastrointestinal bleeding 48 days after operation in cabbage group.
CONCLUSIONEfficacy is similar between the two HALG procedures in lymph node dissection, while reverse procedure has certain advantages, such as less blood loss and faster recovery.

Objective To assess the efficacy and safety of morinidazole combined with appendectomy in treating purulent or gangrenous appendicitis.Methods Double-blind randomized controlled multicenter clinical trial was designed and conducted.Totally 437 patients were included,219 in the control group and 218 in the experimental group.Cases of purulent or gangrenous appendicitis were enrolled and assigned to each of the two groups.The control group received ornidazole injection for 5 to 7 days while the experimental group received morinidazole injection.Both groups underwent appendectomy.Clinical response,micrombiological outcomes,overall response were evaluated.Adverse events and side effects were recorded.Results No significant difference was observed between the two groups regarding the clinical healing rate at 5-10 days after medicine withdrawal,anaerobia clearance and overall healing rates.Adverse events occurred in 140 patients (32.1%).Incidence of adverse events in the control group and the experimental group was 34.7% and 29.4%,respectively (P > 0.05).The overall incidence of side effects was 15.1% (66 cases).Side effects were less seen in the experimental group compared with that in the control group (11.5% vs.18.7%,P < 0.05).The most frequent side effects were aminotransferase rising,thrombocytosis,nausea,vomiting and electrocardiographic abnormality.Conclusions The effect of morinidazole plus operation was comparable with ornidazole in treating purulent or gangrenous appendicitis.The safety of morinidazole is better than ornidazole.
