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.

Objective To study the anticoagulation therapy of lower molecular weight heparin in the treatment of patients with acute pancreatitis.Methods Seventy-three patients with acute pancreatitis were divided into anticoagulation group(n=38)and control group(n=35).The serological indexes and prognosis of patients were detected.Results Anticoagulation treatment with lower molecular weight heparin significantly decreased the white blood cell count,increased the oxygen partial pressure in arterial blood,shoaened the duration of hospitalization,and reduced the aggravation rate,secondary operation rate and mortality of patients with acute pancreatitis.Conclusions Anticoagulation treatment with lower molecular weight heparin is safe,effective and can improve the prognosis of patients with acute pancreatitis.

Objective:To observe the effect of peripheral 5-hydroxytryptophan (5-HT)-induced neutrophil extracellular trap (NET) on lung injury in septic mice.Methods:Wild-type (WT type) and Tph1 knockout (KO) C57 mice (6-8 weeks) were selected and divided into WT mice sham group, WT mice sepsis group, Tph1 KO mice sham group and Tph1 KO mice sepsis group according to the random number table method. Mice in the sham group received sham surgery (only open the abdominal cavity to flip the cecum without ligation and puncture, and then close the abdominal cavity); the mice in the sepsis group received cecal ligation and puncture (CLP) to establish sepsis model. The mice were sacrificed 12 hours after the operation, and the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in bronchialalveolar lavage fluid (BALF) were detected by enzyme linked immunoadsordent assay (ELISA); at the same time, the lung tissues were collected, and the pathological changes of lung tissues were observed under light microscope, and the production of NET in lung tissues was observed by immunofluorescence microscope. Results:The pathological results suggested that the lung tissue structure in sham groups was intact without exudation, while the alveolar structures of mice in the sepsis groups were damaged, with obvious exudation in the alveolar cavity and thickened alveolar walls accompanied by a large number of inflammatory cell infiltration, and the degree of lung injury in the sepsis group of WT mice was more severe than that of the sepsis group of Tph1 KO mice. ELISA results showed that there was no statistically significant difference in the contents of TNF-α and IL-6 in mice BALF from different strains of the sham group; while the contents of TNF-α and IL-6 in BALF of septic mice group were significantly higher than those in sham group [WT mice: TNF-α (μg/L) was 158.20±28.46 vs. 14.00±3.28, IL-6 (μg/L) was 304.98±21.78 vs. 57.70±12.30; Tph1 KO mice: TNF-α (μg/L) was 85.88±20.13 vs. 14.95±1.53, IL-6 (μg/L) was 169.50±45.61 vs. 55.05±12.68, all P < 0.01], and the above index levels in the sepsis group of WT mice were significantly higher than the sepsis group of Tph1 KO mice [TNF-α (μg/L): 158.20±28.46 vs. 85.88±20.13, IL-6 (μg/L): 304.98±21.78 vs. 169.50±45.61, both P < 0.01]. Immunofluorescence staining showed that a very small amount of NET formation was detected in the mice lungs from the sham group; a large amount of NET formation was detected in the lung tissues in the sepsis group, which were significantly higher than those in sham group [WT mice: (34.75±7.27)% vs. (1.75±0.96)%, Tph1 KO mice: (14.25±5.74)% vs. (2.50±1.29)%, both P < 0.01], and the amount of NET produced in the lung tissues of the WT mice sepsis group was significantly higher than that of the Tph1 KO mice sepsis group [(34.75±7.27)% vs. (14.25±5.74)%, P < 0.01]. Conclusions:In sepsis, the increased production of inflammatory factors in the mice lung tissues induces to lung injury. The mechanism may relate to the increased production of NET in the lung tissues mediated by peripheral 5-HT synthesized by enterochromaffin cells and released into the blood; inhibiting the production of 5-HT in the peripheral blood can effectively reduce the production of NET in the lung tissues, thereby reducing lung injury.
