Aim: To study the synthesis and anti-inflammatory activity of p-(sulfamyl) benzylidene-linked hetero-cyclic ketone derivatives. Methods: A series of p-(sulfamyl) benzylidene-linked heterocyclic ketone derivatives were synthesized. Anti-inflammatory activity was evaluated against xylene-induced ear oedema in mice and against carrageenan-induced paw oedema in rats. Gastrointestinal side effects in the rats were also examined after continu-ous introgastric administration of these compounds once daily for 7 days. Results: Twelve compounds( LHZ-101-LHZ-112) were synthesized and their structures were confirmed by IR, ~1H NMR, MS and elemental analysis. LHZ-105, LHZ-106 and LHZ-111 exhibited marked anti-inflammatory activity in xylene-induced mice ear swelling model. LHZ-106 and LHZ-111 showed significant anti-inflammatory activity in carrageenan-induced rat paw ede-ma model. LHZ-105, LHZ-106 and LHZ-111 had less gastrointestinal side effects than diclofenac sodium and CI-1004. Conclusion: These results suggest that some of these compounds have the potential for anti-inflammatory activity with few gastrointestinal side effects.

Objective: To explore the correlation between pull-up ability and upper body composition of male college students in a college in Guangxi, and to provide scientific guidance for college students’ exercise. Methods: A total of 685 male college students were randomly selected from a college in Guangxi.Pull up tests were implemented according to the national physical health test standards. Measurements of muscle mass, fat mass, fat percentage, etc. of the upper limbs were conducted by using the Ogilvy Body Composition Meter (TANITA MC-180). Data entry and analysis were performed by using SPSS 23.0. Results: The pass rate of male college students in the region was 21.7%; There was a statistically significant difference in the fat mass and percentage of body fat between males with different pull-up ability (F=11.30，14.18，12.91，15.22，P<0.01).After controlling age, height, weight and BMI, partial correlation analysis showed that there was a negative correlation between the pull-up ability of male college students and the fat mass and limb fat rate of both upper limbs(r=-0.22, -0.33, -0.31, -0.38, P<0.01). Conclusion The ability of male students in Guangxi to pull up is needed to be improved. Pull-up exercises can reduce fat mass and fat percentage in the upper limbs and improve body composition.

Objective:To investigate the pharmacokinetics of sugammadex in reversal of postoperative residual neuromuscular blockade in obese patients.Methods:Sixteen patients of both sexes, aged 18-65 yr, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, with body mass index of ≥25 kg/m 2, scheduled for elective laparoscopic bariatric surgery, were selected.The patients were divided into 2 groups ( n=8 each) according to the degree of obesity: group O (25 kg/m 2≤BMI<40 kg/m 2) and group M (BMI≥40 kg/m 2). In group O and group M, vecuronium was administered by closed-loop muscle relaxant injection system to maintain moderate neuromuscular blockade.The administration was stopped at the end of surgery, and sugammadex 2 mg/kg was injected according to corrected body weight (CBW) of patients when the muscle relaxation monitoring T 2 recovered naturally.The recovery time of neuromuscular blockade and the occurrence of residual neuromuscular blockade within 3 h after surgery were recorded.Arterial blood samples were collected at 2, 3, 5, 10, 15, 20, 30, 60, 120, 240, 360 and 480 min after administration of sugammadex.The concentration of sugammadex in plasma was determined by ultra-performance liquid chromatography-mass spectrometry.The pharmacokinetic parameters were calculated with PKSolver software. Results:No residual neuromuscular blockade occurred, and the pharmacokinetics of sugammadex in plasma were consistent with the linear non-compartmental model in the two groups.Compared with group O, apparent clearance was increased ( P<0.05), and no significant change was found in other pharmacokinetic parameters, recovery time of neuromuscular blockade and concentrations of sugammadex in plasma at different time point ( P>0.05) in group M. Conclusion:The pharmacokinetics of sugammadex in reversal of postoperative residual neuromuscular blockade in obese patients are consistent with the linear non-compartmental model, and the clearance of sugammadex is higher in morbidly obese patients.

Liver failure （LF） is a great trouble to the majority of patients due to its severe onset， many complications， difficult treatment， poor prognosis and other characteristics. This disease is liver injury caused by infection， hepatotoxic substances， autoimmunity， circulation disorders and other factors. It is a group of common clinical symptoms mainly manifested by coagulation disorders， jaundice， hepatic encephalopathy， ascites， and so on. In traditional Chinese medicine， it falls under the categories of "tympanites"， "jaundice" and other diseases. At present， the research progress of Western medicine in the treatment of LF is slow， and its clinical application effect is still not ideal. In contrast， traditional Chinese medicine has a long history in the treatment of this disease， with over thousands of years of clinical practice and verification. It is characterized by exact efficacy and fewer side effects. The pathological mechanism of LF is extremely complex， involves a variety of signaling pathways， and is mainly related to inflammation， oxidative stress， liver fibrosis， cell apoptosis and other processes. In recent years， many studies have shown that traditional Chinese medicine can intervene in the occurrence and development of LF by mediating relevant signaling pathways in vivo， but there is still a lack of relevant summary. Therefore， this review summarized several signaling pathways related to the intervention of traditional Chinese medicine in LF by referring to and sorting out relevant literature worldwide， including nuclear factor kappa B （NF-κB）， mitogen-activated protein kinase （MAPK）， phosphatidylin-ositol-3-kinase/protein kinase B （PI3K/Akt）， transforming growth factor-β/ drosophila mothers against decapentaplegic proteins （TGF-β/Smads）， and nuclear factor erythroid 2-related factor 2/heme oxygenase-1 （Nrf2/HO-1）， and elaborated the specific mechanism of their intervention in LF. This paper aims to provide practical and effective pathways and corresponding mechanisms for the treatment of LF by traditional Chinese medicine， and to provide new ideas and a theoretical basis for the clinical treatment of LF and further scientific research.
