Objective To observe the effect of nerve growth factor(NGF) on Caspase-3 expression in hippocampus of epileptic rats induced by kainic acid(KA) and explore the protective effect and mechanisms of NGF on the epileptic neurocytes.Methods Sixty healthy rats aged 21 to 30 days were randomly divided into 3 groups,each of which included 20 rats.Rats in group A were treated with 9 g?L-1 sodium,rats in group B were treated with KA,rats in group C were treated with KA and NGF.Concentration of KA was 2 g?L-1 diluted by 9 g?L-1 sodium;KA was injected into rats in group B and group C,intraperitoneally.Then state of seizure was recorded,and EEG and pathological section were performed.Five rats in each group were sacrificed by perfusion with paraform respectively at 6 hour,on the 1st day,on the 3rd day after injection of KA.Specimen was sampled and made into frozen section.Expression of Caspase-3 in hippocampus of epileptic rats was analyzed by immunohistochemistry.And microscope image measuring and analysis instrument was used to analyze image of expression.Results Symptoms of seizure appeared 30 min after injection of KA.Seizure was proved by detection of EEG and pathological section.Expressions of Caspase-3 detected by immunohistochemistry in group C decreased at every time spot were higher than those in group B,and the defferences between 2 groups had statistically significant(Pa

OBJECTIVE:To evaluate the therapeutic effect of compound glycyrrhizin plus mizolastine for patients with generalized neurodermatitis(GND)and its influence on patietents' psychology.METHODS:60 patients with GND were randomly assigned to receive compound glycyrrhizin plus mizolastine(treatment group)or mizolasitine alone(control group)for 28 days.The psychological factors were examined before and after treatment using self-rating anxiety scale(SAS),and the curative effects and the psychological changes between two groups were compared.RESULTS:The SAS scores of treatment group and control group were 30.53? 1.50 and 33.20? 1.67,respectively(P

Epigenetics comprises the modifications made in gene expressions without changing the DNA sequence itself. Significant epigenetic changes take place during spermatogenesis and fertilization and exert direct influences on embryogenesis. This article provides an overview of the latest researches on epigenetics of male germ cells and a brief discussion on the correlation of sperm with embryogenesis in four aspects: DNA methylation, histone modification, regulation of non-coding RNAs, and genomic imprinting.

OBJECTIVETo explore methods and clinical outcomes of microsurgical technique in treating patients with severed palm.

METHODSFrom January 2009 to December 2012,45 patients with severed palm were treated by replantation through microsurgical technique, included 37 males and 8 females, aged from 13 to 45 years old with an average of 25. Postoperative survival rate and evaluation standard of upper limb replantation function posposed by Chinese Medical Association were applied for evaluate clinical outcomes after operation.

RESULTSForty-five patients with severed plam were treated by replantation. Thirty-nine patients (121 fingers) were survived,and survival rate was 87%. All patients were followed up 3 to 15.5 months with an average of 11.5 months. According to evaluation standard of upper limb replantation function posposed by Chinese Medical Association, the total score was 80.27 +/- 1.93, and 27 cases got excellent results, 8 good and 4 poor.

CONCLUSIONThe success of replantation of severed palm depends on grasping operation indication strictly, knowing complexity and local anatomic relationship, debridement completely during operation, making full use of remaining organization, arteriovenostomy through microsurgical technique as early as possible, constructing circulation and repairing injuried nerve rationally.

OBJECTIVETo investigate the semen quality and its influencing factors in preconception males in Nanjing area so as to provide some evidence for working out effective intervention measures.

METHODSTotally 687 men receiving preconceptional physical examination were enrolled in this study. A questionnaire survey was conducted among the subjects along with an analysis of their semen quality.

RESULTSThe median of sperm concentration was 63.3 x 10(6)/ml (95% CI [19.88-119] x 10(6)/ml). The median of grade a sperm was 33.03% (95% CI [19.38-55.05]%), that of grade a + b sperm was 52.08% (95% CI [39.53-69.37]%), and that of teratosperm was 91.75% (95% CI [69-100]%). The median concentration of seminal plasma PMN-elastase was 195.55 ng/ml (95% CI [76.16-3330.38] ng/ml) and that of seminal plasma zinc was 7.62 μmol/L (95% CI [1.5-23, 45] μmol/L). The positive rates of Ureaplasma urealyticum (UU), Chlamydia trachomatis (CT), and Gardnerella vaginalis (GV) were 42.4%, 0.3%, and 2.4%, respectively. The median of sperm DNA fragmentation index (DFI) of those whose wives had a history of adverse pregnancy was 20.25% (95% CI [2.15-68.25]%). Multivariate logistic regression analysis suggested that mental stress (OR 1.567, 95% CI [1.081-2.27]) and sedentariness (OR 1.772, 95% CI [1.211-2.592]) were independent risk factors for asthenospermia.

CONCLUSIONThe sperm quality of preconception males in Nanjing area is not encouraging, and it can be improved by changing undesirable lifestyle and reducing mental stress.
