Objective: To investigate the effects of alcohol, chitosan、 101 juice clarifying agent and ZTC natural clarifying agent on content of active components and the solid compositions in zhonglizhikang decoction. Methods: The solid compositions of different samples were determined by the methods adopted in pharmacopeia, and the chrysophanol content was determined by HPLC. Results: Chitosan has no effect on the content of chrysophanol, and solid compositions decreased by 30.8%. But alcohol、 101 juice clarifying agent and ZTC natural clayifying agent can decrease solid compositions and the content of chrysophanol. Conclusion: Chitosan can decrease solid compositions but has no effect on the content of active components.

Objective To evaluate the clinical significance of direct trocar insertion using optical trocar in the establishment of the primary port during trans-peritoneal laparoscopic surgical procedures.Methods A prospective study was conducted by collecting the data of 120 patients who should be performed abdominal laparoscopic surgery from April 2015 to December 2015.The 120 patients were randomly divided into a research group and a control group.The research group consisted of 34 male patients and 26 female patients,mean age was (52.0 ± 11.9) years and mean BMI was (24.9 ± 2.9) kg/m2.In research group,patients were positioned laterally with the flank padded and elevated.A predetermined position was drawn prior to surgery between the umbilicus and lateral rectus abdominis,for the creation of the primary laparoscopic trocar port.The predetermined point was incised,and then the method of direct trocar insertion using the optical access trocar was used for establishment of the primary port.After this maneuver was completed the surgery continued as indicated.The control group consisted of 36 male patients and 24 female patients,whose mean age was (52.9 ± 11.4) years and mean BMI was (25.2 ± 2.4) kg/m2.This group underwent the traditional method of port construction by incision into the abdomen.The time of constructing the passage,leakage rate,bleeding rate,and injury rate of abdominal organs were compared.Results In research group,the time of building primary port was clearly shorter than that in control group (2.7min vs.15.9min,P ＜ 0.05),the leakage rate was also obviously reduced compared to that in control group (0 vs.30％,P ＜ 0.05).Neither groups observed any significant bleeding nor visceral organ damage throughout the study.Conclusion Direct trocar insertion using optical trocar to establish observation port is a highly efficient and safe method in trans-peritoneal laparoscopic operation,which should be research thoroughly in clinical practice.

Objective To evaluate the clinical efficacy and safety of sibutramine (Reductile )in Chinese obese patients. Methods Obese adults (BMI 27～45 kg/m 2) in six research centers received sibutamine 10 mg or placebo one tablet each day with a controlled-energy diet for 24 weeks by randomized, double-blinded, placebo-controlled study. Results For intent-to-treat analysis, 125 sibutramine-treated subjects and 126 placebo-treated subjects were evaluated. After 24 weeks, sibutramine-treated patients lost more weight (6.52?3.95)kg than placebo-treated patients (3.18?3.59)kg(P

Aim To clone and express the 1.2kb cDNA fragment (1/753-2 934bp) of human integrin α 4 subunit. Methods The 1.2 kb cDNA fragment of human integrin α 4 subunit was amplified from HL-60 total RNA by RT-PCR, then it was subcloned into expression vector pGEX-3X and induced with IPTG. Results The 1.2 kb cDNA fragment of human integrin α 4 subunit was cloned. The sequencing indicated that there was only one missense mutation (Arg→ Gln) among the fragment, and this mutation won't affect antigenicity after analysed by GOLDKEY. Then the 1.2 kb cDNA was subcloned into expression vector pGEX-3X. The α 4 fragment was highexpressed in E.coli after induced with IPTG. Conclusion The 1.2kb cDNA fragment of α 4 subunit was obtained, and it was highexpressed in E.coli, it might be important for study on the function of α 4 integrins.
