One hundred and fifty ASA Ⅰ-Ⅱ infants scheduled to undergo surgery on unilateral inguinal region,were randomly assigned to 3 groups with 50 in each group.In groups Ⅰ and Ⅱ puncture was performed at traversus abdominis plane under ultrasound-guidance,0.4 or 0.5/kg of 0.25％ ropivacaine was injected respectively.In group Ⅲ the triangle of Petit was positioned through palpating and then 0.5 ml/kg of 0.25％ ropivacaine was injected.HR,RR,SpO2,PETCO2,expired sevoflurane concentration and BIS value at the time of entering the operation room (T1),incision of skin (T2),pulling hernia sac (T3),ending the surgery (T4),waking (T5),the number of pressing the analgesia pump after operation were recorded.The results showed that HR at T2 and T3 of groups Ⅰ and Ⅱ was lower than group Ⅲ (P ＜ 0.05).The were significant differences in case numbers of insufficient intraoperative analgesia among 3 groups(x2 =10.500,P =0.005).The CHEOPS scores and the number of pressing analgesia pump after operation in groups Ⅰ and Ⅱ were lower than those in group Ⅲ (x2 =7.230,P =0.027).Results indicate that ultrasound-guided transversus abdominis plane block is safer and more effective than conventional method for operations of inguinal region in infants; it may reduce dose of local anesthetics and postoperative use of analgesics.

Objective:To determine the gestational weight gain and its risk factors and adverse effects among pregnant women in Beijing.Methods:Between June 2018 and June 2019, all registered infants and their mothers in a child care center of a third-tier-class hospital in Beijing were selected. A self-made questionnaire was used to collect the basic information of the maternal mothers. Chi-square test and analysis of variance were used to describe the basic characteristics of the study subjects and clarify the harmful effect of gestational weight gain for maternal and infant health. Multiple logistic regression analysis was used to analyze the risk factors of both insufficient and excessive weight gain during pregnancy.Results:A total of 3732 maternal mothers and their babies were included. The average weight gain of maternal mothers during pregnancy was 13.0 kg. The results of this study showed that the proportion of insufficient weight gain during pregnancy was 31.8% and the proportion of excessive weight gain was 24.1%. It was further found that young age, pre-pregnancy body mass index indicating overweight and obesity, primipara, and low education were independent risk factors for excessive weight gain during pregnancy. The risk of excessive weight gain of pre-pregnancy overweight and obesity was 2.40 times ( OR=2.40, 95% CI=1.91-3.03, P<0.001) and 2.90 times higher, respectively, ( OR=2.90, 95% CI=1.59-5.27, P<0.001) when compared with that of pre-pregnancy normal weight. In addition, our results suggested that excessive weight gain significantly increased the risk of macrosomia for the infant and the risk of cesarean section, gestational hypertension, and postpartum weight retention for maternal mothers. Conclusions:Age, pre-pregnancy BMI, primipara, and education level were the influencing factors for gestational weight gain. Considering the serious harmful effects of both insufficient and excessive weight gain for maternal and infant health, weight management during pregnancy should be strengthened for these high-risk populations in the future.

Sarcomatoid carcinoma of the renal pelvis is rare. One case of sarcomatoid carcinoma of the left renal pelvis was reported. The patient was diagnosed as sarcomatoid carcinoma of left pyelonephrosis by left percutaneous nephrolithotripsy (PCNL) and biopsy of left pyelonephrosis in another hospital due to left lumbar pain.The patient came to our hospital for laparoscopic left hemiculturectomy and was pathologically diagnosed as left renal pelvic sarcomatoid carcinoma. The patient suffered left retroperitoneal recurrence and bilateral lung metastasis 7 months after surgery and died of cachexia 10 months later.

OBJECTIVE To study the effects of Ganbao capsules on intestinal mucosal barrier and gut microbiota in rats with non-alcoholic fatty liver disease （NAFLD）， and to explore its mechanism of prevention and treatment of NAFLD. METHODS Eight of 26 SD rats were randomly selected as blank group and fed with ordinary diet， and the remaining 18 rats were fed with high diet to establish NAFLD model （2 for modeling inspection）； after successful modeling， they were divided into model group and Ganbao group， with 8 rats in each group. Ganbao group were given Ganbao capsules solution （1 440 mg/kg） intragastrically， and the blank group and model group were given the constant volume of distilled water intragastrically， once a day， for consecutive 5 weeks. The contents of alanine aminotransferase （ALT）， aspartate aminotransferase （AST） and triglyceride （TG） in serum of rats were detected by automatic analyzer； the contents of lipopolysaccharide， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6） and IL-1β in serum of rats were detected by enzyme-linked immunosorbent assay. The pathological morphology of liver and ileum tissues were observed by HE staining， the expressions of Occludin and zonula occludens-1 （ZO-1） were detected by immunohistochemistry method， and the intestinal flora were detected by 16S ribosomal RNA gene sequencing technology. RESULTS Compared with the model group， the serum contents of ALT， AST， TG， lipopolysaccharide， TNF-α， IL-6 and IL-1β in Ganbao group were decreased significantly （P＜0.01）， the pathological changes of liver and ileum tissues were improved 262 significantly， and the expressions of Occludin and ZO-1 were increased significantly （P＜0.01）. Intestinal microbiotaanalysis revealed that compared with the model group， Ganbao capsules could recover the abundance and diversity of the gut E-mail：hdf8833@126.com microbiota in rats. At the phylum level， Ganbao capsules could significantly increase the relative abundance of Bacteroidetes， and significantly reduce the relative abundance of Firmicutes and the ratio of Firmicutes to Bacteroidetes （P＜0.01）. At the genus level， Ganbao capsules could significantly increase the relative abundance of Lactobacillus， Blautia， Bacteroides and Akkermansia， and significantly reduce the relative abundance of Prevotella， Turicibacter， Weissella， SMB53 and Desulfovibrio （P＜0.05 or P＜0.01）. There were different species among the gut microbiota of rats in each group. CONCLUSIONS Ganbao capsules may improve NAFLD by protecting intestinal mucosal barrier function and regulating gut probiotics/harmful bacteria structure.
