Objective:To discuss the influence of bifid triple viable enteric-coated capsules on liver function and inflammatory fac-tor in the patients with non-alcoholic steatohepatitis ( NASH) . Methods:Totally 70 cases of patients with NASH were selected and di-vided into the control group and the observation group at random. The patients in the two groups were all given routine hepatoprotective therapy. The patients in the observation group were additionally given 420mg bifid triple viable enteric-coated capsules, three times a day for 4 weeks. Except for bifid triple viable enteric-coated capsules, the patients in the control group were given the same medical treatment as that in the observation group. The changes of liver function index, serum high sensitivity C reaction protein ( hs-CRP) , IL-6 and IL-8 levels in the two groups before and after the medical treatment were observed and the security was compared. Results:After the 4-week medical treatment, ALT, GGT, serum hs-CRP, IL-6 and IL-8 levels in the two groups were obviously declined than those before the treatment (P<0. 05 or P<0. 01), and the declining rate in the observation group was much higher than that in the control group (P<0. 05). Totally 6 and 4 cases of adverse drug reaction (ADR) respectively appeared in the observation group and the control group during the medical treatment with mild symptom, and the difference was without statistical significance (P>0. 05). Conclusion:Bifid triple viable enteric-coated capsules in the treatment of NASH can obviously reduce the serum hs-CRP, IL-6 and IL-8 levels, inhibit the intrahepatic inflammation and immunologic injury, and improve the liver function index with high security.

Objective To evaluate combined sampling at multiple sites of gastric mucosa for Helicobacter pylori (HP) culture.Methods A total of 258 patients with upper gastrointestinal symptoms received 13C-urea breath test between August 2014 and May 2015.During endoscopy,gastric mucosa biopsy samples from the lesser curvature of the antrum (A),the greater curvature of the antrum (B),gastric angle (C) and the body of the stomach (D) were collected to isolate HP strains.The positive rates of HP based on combined sampling and single site sampling were compared with a Nemenyi test.Results Consistency between 13C-urea breath test and HP culture was 82.56％.There was significant difference between the single site sampling and two-site sampling in the positive rate of HP,except for the body of the stomach (P＜0.05).There was significant difference in the positive rate of HP between the single site sampling and three-site sampling (P ＜ 0.05).There was no significant difference between any two-site sampling in the lesser curvature of the antrum and the body of the stomach,gastric angle and the body of the stomach,the greater curvature of the antrum and the body of the stomach,and any three-site sampling (P＞0.05).Conclusion The combined sampling of the lesser curvature of the antrum and the body of the stomach have the highest cost-effectiveness in HP culture compared with the single site sampling and three-site sampling.

AIMTo establish a method for cynomolgus monkey sperm cryopreservation in a chemically defined extender.

METHODSSemen samples were collected by electro-ejaculation from four sexually mature male cynomolgus monkeys. The spermatozoa were frozen in straws by liquid nitrogen vapor using egg-yolk-free Tes-Tris mTTE synthetic extender and glycerol as cryoprotectant. The effects of glycerol concentration (1 %, 3 %, 5 %, 10 % and 15 % [v/v]) and its equilibration time (10 min, 30 min, 60 min and 90 min) on post-thaw spermatozoa were examined by sperm motility and sperm head membrane integrity.

RESULTSThe post-thaw motility and head membrane integrity of spermatozoa were significantly higher (P0.05) for 5 % glycerol (42.95 +/- 2.55 and 50.39+/- 2.42, respectively) than those of the other groups (1%: 19.19 +/- 3.22 and 24.84 +/- 3.64; 3%: 34.23 +/- 3.43 and 41.37 +/- 3.42; 10%:15.68 +/- 2.36 and 21.39 +/- 3.14; 15%: 7.47 +/- 1.44 and 12.90 +/- 2.18). The parameters for 30 min equilibration(42.95 +/- 2.55 and 50.39 +/- 2.42) were better (P0.05) than those of the other groups (10 min: 31.33 +/- 3.06 and 38.98 +/- 3.31; 60 min: 32.49 +/- 3.86 and 40.01 +/- 4.18; 90 min: 31.16 +/- 3.66 and 38.30 +/- 3.78). Five percent glycerol and 30 min equilibration yielded the highest post-thaw sperm motility and head membrane integrity.

CONCLUSIONCynomolgus monkey spermatozoa can be successfully cryopreserved in a chemically defined extender, which is related to the concentration and the equilibration time of glycerol.
