The embryos collected were subjected to the following procedures: ①Total RNA was isolated from embryos of each stage respectively and mRNA expression of leptin was detected by RT-PCR. ②Immunofluorescence staining was performed on blastocysts to analyze the expression and the distribution of leptin protein under laser confocal microscope. ③Eight-cell embryos were cultured in medium containing leptin antibody at various concentrations to observe the formation and hatching of blastocysts. Results ①Leptin mRNA expression was only detected in blastocyst,and no expression was detected in embryos in other stages. Leptin protein was detected in cytoplasma,membrane of trophoblastic cell and inner cell mass,however no expression was detected in cell nucleus. ②Leptin polyclonal antibody significantly inhibited formation of blastocysts (1∶400,P

Taurine is one of the extremely important amino acids in the body,and is also the most abundant free amino acids in the central nervous system(CNS).Taurine as a conditional essential amino acids exerts a wide range of physiological and pharmacological effects.Taurine,especially as a neurotransmitter in the developing CNS,can maintain the structural integrity of the membrane,regulate calcium transport and calcium homeostasis,also as nutritional factors,osmolyte,neuromodulator,neuroprotective agents,plays an important role.In this paper,physiological and biochemical properties of taurine,source and distribution in vivo,synthesis and metabolism,absorption and transport,and its protective effect on the CNS are reviewed.

Objective The incidence rate of complication during central venous catheterization through internal jugular vein (IJV) and subclavian vein (SV) puncture. Methods Clinical controlled trials about IJV and SV puncture were collected and related literatures were screened according to the criteria of inclusion. The literatures underwent Meta analysis and subsequent analysis of sensitivity. Results A total of 18 literatures were included. Meta analysis indicated that statistical difference existed in the related infection rate [RR=1.74, 95%CI (1.32, 2.30)] and arterial puncture [RR=3.19, 95%CI (1.70, 5.99)], but not in the one-time-puncture success rate [RR=1.06, 95%CI (0.90, 1.24)] between IJV and SV puncture. Conclusions The rate of related infection and arterial puncture was higher by IJV than by SV puncture. But we could not confirm if any difference existed in the one-time-puncture success rate between the two methods. The results still needs evaluation by high-quality randomly controlled experiments.

OBJECTIVE:To observe clinical efficacy and safety of individual antiviral therapy of tenofovir combined with inter-feron α1b for chronic hepatitis B (CHB). METHODS:96 CHB patients were randomly divided into control group,observation group A and observation group B,with 32 cases in each group. Control group was given entecavir orally,0.5 mg,qd;observation group A was given tenofovir orally,1 piece,qd;observation group B was additionally given interferon α1b,50 μg,3 times a week,on the basis of observation group A. The treatment course lasted for 48 weeks in 3 groups. Clinical efficacy of 3 groups was compared,and the changes of serum liver function indexes,HBV-DNA negative conversion rate and the occurrence of ADR were compared before and after treatment. RESULTS:The total effective rate of observation group B(84.38%)was significantly higher than that of observation group A(62.60%)and control group(37.50%),and that of observation group A was significantly higher than control group,with statistical significance (P<0.05). Compared with before treatment,the serum levels of AST,ALT and TBIL were significantly decreased after treatment in 3 groups;the observation group B were significantly lower than those of obser-vation group A and control group,with statistical significance(P<0.05);there was no statistical significance between observation group A and control group(P>0.05). The negative rate of HBV-DNA in observation group B were significantly higher than those in control group and observation group A after 12 and 24 weeks of treatment,with statistical significance(P<0.05);there was no statistical significance between observation group A and control group (P>0.05). No obvious ADR was found in 3 groups. CON-CLUSIONS:Tenofovir combined with interferon α1b shows significant clinical efficacy for CHB,and is significantly better than that of entecavir and tenofovir alone.

ObjectiveTo determine the optimal timing of antenatal taurine supplementation to improve neuron and neural stem cell proliferation in fetal rats with intrauterine growth restriction.Methods Twenty-five pregnant SD rats were randomly divided into five groups (five rats in each group): group A was the control group, group B to E were the fetal growth restriction (FGR) model groups with low-protein diet during the experiment, group C, D, and E were supplemented with taurine [300 mg/(kg·d)] at day 9, 11 and 15, respectively. The birth weight of newborn rats was measured after natural delivery. The rats with body weight two standard deviations lower than the average weight in group A were diagnosed as FGR. There were five litters of newborn rats in each group, and two were randomly selected from each litter, resulting in ten newborn rats in each group. Proliferating cell nuclear antigen (PCNA) and fatty acid binding protein 7 (FABP7) positive cell expression in newborn rat brain tissues were detected by immunohistochemistry. Single factor analysis of variance, LSD tests were used for statistical analysis.ResultsThe average birth weight of newborn rats in group A, B, C, D and E were (6.61±0.45), (4.65±0.23), (5.37±0.17), (5.74±0.21), and (5.00±0.24) g, respectively. Average birth weight was lower in group B than in group A (t=2.447), higher in group D and E than in group B (t=2.306 and 2.306), higher in group D than in group C and E (t=2.306 and 2.306), and the differences were statistically significant (allP<0.05). The positive expression of PCNA in the brain of neonatal rats was mainly located in the nucleus. The number of PCNA positive cells in each high power field (×400) in group A, B, C, D and E was 31.03±5.38, 46.49±4.38, 59.65±5.37, 67.76±5.84, and 53.53±6.94, respectively. The number of PCNA positive cells in group B was higher than that in group A (t=2.110), higher in groups C, D and E than in group B (t=2.110, 2.110 and 2.131), higher in group D than in group C and E (t=2.101 and 2.110), and the differences were all statistically significant (allP<0.05). The positive expression of FABP7 was mainly located in the cytoplasm of neonatal rat brain. The integral optical density (IOD) in group A, B, C, D, and E was 451 733.1± 141 452.3, 207 232.2±60 525.2, 333 766.6±68 412.1, 380 647.4±131 145.9, and 278 967.1±127 630.7, respectively. The IOD in group B was lower than that in group A (t=3.165,P=0.000), higher in groups C, D and E than in group B (t=5.272, 7.132, 2.950), and the differences were statistically significant (allP<0.05). Although the IOD in group D was higher than that in group C, the difference was not significant (t=1.953, P>0.05). The IOD in group D was higher than that in group E, and the difference was statistically significant (t=4.182,P<0.05).ConclusionsAntenatal taurine supplementation can promote neuron and neural stem cell proliferation in rats with FGR. The effect is most obvious on the 11th day of pregnancy, and may lead to the promotion of brain development.
