The pathogenic and therapeutic effect of gut microbiome is a hot topic in recent years .Many researchers gradually focused on the relationship between the eating disorder and the gut microbiome .The gradual in-depth studies show that gut microbiome can intervene in the host′s metabolic state by multiple approaches to regulate appetite and bring new inspiration for the treatment of dis -eases.In this article, we review all important findings in this field and discuss the mechanism how gut microbiome effects appetite regu -lation.

Objective The purpose of this study was to establish and evaluate a mouse model of sepsis for studying the mechanism of sepsis and development of anti-inflammatory drugs.Methods The sepsis in mice was induced by cecal ligation and puncture ( CLP) .The survival rates, microbial load, liver and kidney damages, cytokines and pathological changes were detected to evaluate the mouse models.Results The death of mice was closely related with the ligated sites. The mice with 50%cecal ligation displayed about 40% of 12-day survival rate, however, all the mice with 75% cecum ligation died within 4 days (P<0.01).Compared with the sham surgery group, the mice with 50% cecal ligation had a high microbial load in the blood and abdominal cavity.Leukopenia was also emerged (P<0.001).CLP mice demonstra-ted elevated levels of serum ALT, AST and BUN (P<0.01).The levels of IL1α, IL6, IL10, MIP1α, MIP1β, and TNFαwere increased a lot.The liver and lung showed obvious pathological injury at 48 h post CLP.Conclusions The established mouse model of CLP shows typical characteristics of sepsis and is an ideal tool for further study of anti-inflam-matory drugs.

Background and purpose:Traditional Chinese medicine with notable effect and little adverse reaction is increasingly concerned about the medical profession because of its great potential and advantage in treating pancreatic carcinoma. In this experiment, we studied the effects of oridonin on apoptosis and cytoskeletal protein F-actin in human pancreatic carcinoma SW1990 cells. Methods:SW1990 cells in culture medium were treated with different concentrations of oridonin. The inhibitory rate of the cells was measured by MTT assay. Morphology of cell apoptosis was observed by DAPI stain and cell apoptotic rate was detected by lfow cytometry (FCM). The morphological changes of F-actin were observed by laser confocal microscopy. Results:The growth of human pancreatic carcinoma SW1990 cells was signiifcantly inhibited by oridonin. Apoptosis morphological changes including condensation of chromatin and nuclear fragmentation were observed clearly by DAPI stain. The early apoptotic rate of SW1990 cells treated with 25, 50μmol/L oridonin was signiifcantly higher than that of the control group (3.78±0.46, 9.51±0.63 vs 0.73±0.06, P<0.05), and the late apoptotic rate and cell necrosis rate were also signiifcantly higher than that of the control group (14.40±1.78, 20.53±2.54 vs 4.16±0.31, P<0.05). F-actin was showed from polymerization to depolymerization after oridonin treatment. Conclusion:Oridonin can obviously inhibit the proliferation and induce apoptosis of SW1990 cells. The mechanisms may involve the depolymerization of F-actin after treatment with oridonin.

OBJECTIVETo investigate the clinical application of laparoscopy-assisted subtotal colectomy with transanal specimen extraction for slow transit constipation(STC).

METHODSRetrospective analysis was performed on the clinical data of 8 cases with STC undergoing the procedure mentioned above from February to November 2013. Pre-and post-operative constipation was assessed using Wexner Constipation and Incontinence Scales, and quality of life was assessed using Gastrointestinal Quality of Life Index.

RESULTSAll the operations were completely successful without postoperative complications, such as intestinal fistula, pelvic infection, anastomotic stricture, intestinal obstruction. The Operative time was (287.6 ± 21.5) min, blood loss was (109.7 ± 41.1) ml, time to first flatus was (2.5 ± 0.9) d. The proportion of postoperative constipation symptom index improvement was(77.6 ± 8.3)%. Postoperative quality of life score was 97.3 ± 15.7, significantly higher than that before operation(P<0.05). Postoperative Wexner constipation score was 8.8 ± 3.7, significantly lower than that before operation.

CONCLUSIONLaparoscopy-assisted subtotal colectomy with transanal specimen extraction in the treatment of STC has good short-term efficacy with obvious improvement in quality of life.

Objective To evaluate the effect of stellate ganglion block (SGB) on postoperative synaptic structure in hippocampal CA3 region in aged rats.Methods Seventy-two male Sprague-Dawley rats,aged 20-22 months,weighing 550-650 g,were randomly divided into 3 groups (n =24 each) using a random number table:control group (group C),operation group (group O) and SGB + operation group (group SGB).Group SGB received right SGB with 0.25％ bupivacaine 0.15 ml.Groups O and SGB underwent 30 min of exploratory laparotomy starting from 15 min after the end of administration.Y-maze test was performed on 1 day after operation in 6 rats chosen from each group for assessment of cognitive function.The frequency of standard training and standard time were recorded.Six rats were chosen from each group on 1,3 and 7 days after operation and sacrificed and the hippocampal CA3 region was isolated for microscopic examination and for measurement of synaptic structure.Results Compared with group C,the standard time was significantly prolonged,and the frequency of standard training was increased in groups O and SGB,the width of synaptic cleft was increased,the thickness of post-synaptic density was decreased,the length of active zones was shortened,and the curvature of the synaptic interface was decreased on 1,3 and 7 days after operation in group O (P ＜ 0.05),and no significant changes were found in each synaptic structure parameter in group SGB (P ＞ 0.05).Compared with group O,the standard time was significantly shortened,the frequency of standard training was decreased,the width of synaptic cleft was decreased,the thickness of the post-synaptic density was increased,the length of active zones was prolonged,and the curvature of the synaptic interface was increased on 1,3 and 7 days after operation in group SGB (P ＜ 0.05).Conclusion The mechanism by which SGB improves the postoperative cognitive dysfunction in aged rats may be related to inhibition of changes of synaptic structure in hippocampal CA3 region.

OBJECTIVETo investigate the effect of berberine on serum levels of TNF-alpha, IL-6 and adiponectin in obese mice induced by high fat diet and its potential molecular mechanisms.

METHODNormal male Kunming mice were randomly divided into two groups taking normal chow (NC, n = 10) and high fat diet (HF, n = 30), respectively. After 13 weeks, HF mice were continuously given high fat diet and divided into three groups, model group (BM), low-dosage of berberine group (BL) and high-dosage of berberine group (BH). Mice in BL and BH were administered berberine by gavage at the dosage of 50 mg x kg(-1) and 150 mg x kg(-1), respectively. Two weeks later, oral glucose tolerance test was performed. At the end of the experiment, the mice were killed and blood samples were collected. The epididymal fat tissue and liver were removed promptly and weighed. The serum cytokine was measured by ELISA. The levels of IkappaB kinase beta (IKK-beta) and IKK-beta (ser181) were detected by Western blotting.

RESULTSerum levels of TNF-alpha, IL-6 in mice of BM were significantly higher than those in NC (P < 0.05). After two-week treatment of berberine, serum levels of TNF-alpha, IL-6 in BL and BH were lower than those in BM (P < 0.05, respectively). However, there were no significant difference of adiponectin among four groups. The degrees of phosphorylation of IKK-beta (ser181) were decreased in liver and adipose tissue in BH in comparison to that in BM, although the expression of total IKK-beta did not change. Furthermore, the glucose tolerance was improved, while the body weight and epididymal fat were reduced in mice treated with berebrine. 9: Berberine is able to reduce inflammatory cytokines expression and inhibit activation of IKK-beta (ser181) in obese mice, which may partly explain the therapeutic effect of berberine on insulin resistance and abnormal glucose metabolism.
