[Summary] Bile acid is a main component of bile ,which plays a key role in keeping cholesterol metabolism balance in vivo and promoting lipids digestion in intestine. Recently ,more and more researches focus on bile acid for its regulating effect on glucose ,lipid and energy metabolism as a signal molecule. The reabsorbed bile acid stimulates the secretion of fibroblast growth factor 19 (FGF19) and glucagon-like peptide-1(GLP-1) in the intestine by activating a nuclear receptor farnesoid X-activated receptor (FXR) and a membrane receptor TGR5. FGF19 and GLP-1 regulate hepatic glucose metabolism through different pathways. Here ,we briefly summarize the research progress and relationship between bile acid induced gut hormones and hepatic glucose metabolism.

The origin and development of umbilical therapy in traditional Chinese medicine is explored from related literature in the history. As a result, the Shang period is regarded as initial period of umbilical therapy, while periods from Han Dynasty, Jin Dynasty and Southern-Northern Dynasties to Sui Dynasty and Tang Dynasty could be taken as stage of primary development. Time from Song Dynasty, Jin Dynasty and Yuan Dynasty to Ming and Qing Dynasties is believed as mature stage. Also the manipulation, application principle, indications and contraindications of umbilical therapy are explained. A brief overview of modern development of umbilical therapy is also described.

Objective To study the relationship between smoking and the incidence of pulmonary tuberculosis(TB) in Chinese people.Methods The Pubmed database and three Chinese databases such as Wanfang Data,Veipu data(VIP) and China national knowledge infrastructure database (CNKI) were retrieved.The literatures on the relationship between smoking and pulmonary TB incidence in Chinese people published before April 2016 were analyzed.Results Fifteen studies were included,after excluding 1 low quality study,the rest had no statistical heterogeneity.The merged odd ratio (OR) was 1.71,95 ％ confidence interval (CI) 1.51-1.90.Two studies observed the relationship between the amount of cigarettes and TB pathogenesis,but there was heterogeneity and could not be further merged the OR value for conducting analysis.No subgroup analysis of gender was performed in all studies.Conclusion The risk suffering from pulmonary TB in Chinese smokers is 1.71 fold of non-smokers,and smoking increases the risk of pulmonary TB onset.

Objective:To prepare and optimize sorafenib-Eudragit RS nanoparticles( S-E üPs)and investigate the physicochemi-cal properties. Methods:S-E üPs were prepared by a solvent-nonsolvent method. Single factor experiments were used to research the effect of solvent,stabilizer type,carrier ratio and the proportions of water phase and organic phase on the physicochemical properties of S-E üPs. S-E üPs were evaluated by the particle size,zeta potential and morphology,and the in vitro drug release of S-E üPs was studied using dialysis technology. Results:The mean size was(86. 72 ± 3. 71)nm,the PDI and zeta potential was(0. 20 ± 0. 032)and (36. 6 ± 0. 3)mV,respectively,S-E üPs showed spherical shape with uniform distribution. The drug release in vitro was accorded with a Weibull equation. Conclusion:The solvent-nonsolvent method is appropriate for the preparation of S-E üPs. The nanoparticles have small particle size,uniform distribution,regular morphology and significant sustained-release property.

Objective To evaluate the effect of continuous adenosine infusion on mesentery microcirculation during cardiopulmonary resuscitation in rats with asphyxia. Methods Rat model of asphyxia was established in 22 healthy Wistar rats. The animals were then randomly divided into normal saline group (group A, n=10), epinephrine group (group B, n=6) and epinephrine plus adenosine group (group C, n=6). After a 3-min asphyxia without intervention, cardiopulmonary resuscitation (CPR) was started. The cardiac compression was carried out with an electric cardio-pulmonary resuscitation machine (200 times/min). Respiration was restored and maintained with a ventilator with tidal volume of 4ml, breathing rate 50times/min and FiO2 100%. After a 4-min CPR, rats in group A and group B were given normal saline and epinephrine (bolus of 90?g/kg) respectively, and in group C epinephrine (bolus of 90?g/kg) plus 70?g/kg adenosine were given. Electric defibrillation would be initiated if there was ventricular fibrillation. The reperfusion rate of mesentery arterioles and venules, diameter of blood vessels and relative blood velocity were observed. Results The reperfusion rate of mesentery arterioles and venules was significantly higher in group C than in group B (P

Objective To test thyroid-stimulating hormone (TSH) suppress GLUT4 expression and translocation by stimulating TNF-α secretion in 3T3-L1 adipocytes via a cAMP-PKA pathway.Methods 3T3-L1 preadipocytes were induced to differentiate into adipocytes.The adipocytes were treated with bovine TSH,Forskolin,H89 and Rapamycin,respectively.The concentration of TNF-α in the cell culture medium was measured by ELISA.The level of GLUT4 mRNA in adipocytes was assessed by real time polymerase chain reaction.Protein levels of GLUT4 in total cell lysates and plasma membrane lysates were quantified by Western blotting.Results Incubating 3T3-L1 adipocytes with TSH markedly increased the concentration of TNF-α in medium in a time-and dosedependent manner (P ＜ 0.05); meanwhile,the levels of GLUT4 mRNA and total and plasma membrane GLUT4 protein were decreased in a dose-dependent manner (P＜0.05 or ＜0.01).H89 and rapamycin could block the above effects respectively (326.7±43.2 vs.341.9±12.0,P＞0.05).However,there was no statistical difference in the TNF-α levels between stimulation with 1 μmmol/L forskolin versus 0.04 μmmol/L bovine TSH (481.9± 28.4 vs.522.7± 36.2,P＞0.05).Conclusions TSH can down-regulate GLUT4 expression and translocation in 3T3-L1 adipocytes by stimulating TNF-α secretion through a cAMP-PKA pathway.

Background:Eosinophilic gastroenteritis is the most common gastrointestinal allergic disease,however,allergy also accounts for some gastrointestinal functional disorders. The correlation between allergic factor and intestinal polyp is not clarified. Aims:To investigate the correlation of allergic factor with intestinal polyp and irritable bowel syndrome(IBS). Methods:Ninety-five inpatients including 60 cases of intestinal polyp and 35 cases of IBS admitted from May 2012 to April 2014 were recruited;95 healthy volunteers were served as controls. Serum samples were collected to test specific IgE antibodies derived from 20 common inhalant and alimentary allergens by EUROIMMUN blotting test. Results:The positivity rates of allergen specific serum IgE antibodies in intestinal polyp group,IBS group and both two groups were 56. 67% ,74. 29% and 63. 16% ,respectively,all were significantly higher than that in control group(6. 32% ,P all <0. 05),but no statistically significant difference was seen between intestinal polyp group and IBS group(P > 0. 05). In all the 20 allergens tested,the positivity rates of Dermatophagoides,roach,crab,sea fish,freshwater fish,shrimp,and egg albumin specific serum IgE antibodies were significantly higher in patients group than in control group( P < 0. 05), especially the crab,see fish and Dermatophagoides specific IgE antibodies. Conclusions:Allergic factor might have some association with intestinal polyp and IBS.

Objective To study the changes of umbilical blood lactate,pH, blood sugar(BS),bilirubin, electrolyte, osmotic pressure (OP) in the newboms with fetal distress.Methods Thirty-five newborns with fetal distress (distress group) and 40 healthy new-borns (control group) were studied. Distress group were divided into distress group Ⅰ and distress group Ⅱ respectively, based on without or with neonatal asphyxia. Concentration of umbilical blood lactate was determined with enzyme method, pH, BS,serum total bilirubin (BIL), serum electrolyte (Na+ ,K+ ,Ca2+ ) and OP were analyzed respectively. Results 1. The difference of incidence of newborn asphyxia between distress groups (29.03%) and control group (2.50%) was statistically significant. 2. Compared with the controls and distress group Ⅰ, the umbilical blood lactate concentration significantly increased in distress group Ⅱ (P 0.05).The incidence of hyperglycemia was significantly elevated in distress groups than that in the control group. 4. Lactate concentration in distress I and distress fl group showed negative correlation with pH. Conclusion The concentration of umbilical blood lactate can provide the proof for diagnosis and prognosis of fetal distress.
