Objective: To investigate the effects of the exogenous testosterone propionate on apoptosis of rat germ cells and the mechanisms thereof. Methods: Thirty 35-day-old male SD rats were randomly divided into experimental group and the control group. The rats in experimental group were injected (i.m.) testosterone propionate and the control group with an equal volume of saline. By using terminal deoxynueleotidy transferase nediated dUTP nick-end labeling (TUNEL), flow cytometry (FCM), radioimmunoassay (RIA) and electron microscopy, the quantity and quality of apoptosis of germ cells were evaluated. Results:(1) Compared with the control, the apoptotic number of rat germ cells was increased in the experimental group, especially the primary spermatocyte. The apoptotie rate was 11.3% detected by FCM in experimental group,while 3.6% in the control group (P ＜ 0.01). (2) The percentages of 1C were 21.8% in experimental group and 33.8% in control group (P ＜ 0.01).The percentages of 2C were 52.6% in experimental group and 37.1% in control group (P ＜ 0.01). (3) The serum levels of testosterone were (3 486.8±333.3) ng/L in experimental group and (846.9±167.5) ng/L in control group (P ＜ 0.01). The serum levels of follicle-stimulating hormone (FSH) were (2.5±0.8) IU/L in experimental group and (5.2±1.7) IU/L in control group (P ＜0.01). Conclusion: The exogenous testosterone propionate might induce apoptosis of germ cells by retroinhibition of the hypothalamie-pituitary-gonadal axis, thus having contraceptive effects.

Bacterial extracellular metalloproteases ( BEMPs) are a large group of metal ion-contai-ning proteases. All BEMPs identified so far are endopeptidase or endoprotease. BEMPs can be classified into nine metalloprotease families based on the sequences and structures of enzymatic molecules. Double-valence zinc ion ( Zn2+) is necessarily required by catalytic centers of most BEMPs. The main function of BEMPs in non-pathogenic heterotrophic bacteria is to hydrolyze environmental proteins and polypeptides to provide vari-ous amino acids as nutrients. However, BEMPs of pathogenic bacteria, serving as important virulence fac-tors, help the pathogens invade into hosts and spread in hosts. In recent years, the roles and mechanism of BEMPs in bacterial pathogenesis have attracted great attention. Here, we make a brief review about the structures and types as well as the functions and pathogenic roles of BEMPs.

To construct a eukaryotic vector and establish a gastric cancer cell model highly expressing zinc ribbon protein gene ZNRD1, ZNRD1 cDNA was inserted into multiple cloning sites of the pcDNA3 1 + with molecular cloning technique. The recombinant vector was identified by endonuclease digestion and transfected into SGC7901 cells by nucleus microinjection. Northern blot was used to detect the expression of ZNRD1 in cells. The results showed that ZNRD1 was successfully cloned into pcDNA3 1 + and microinjected into SGC7901. Therefore, a gastric cancer cell model highly expressing ZNRD1 has been established and can be used for further functional research of this gene.

Objective To discuss the problem of upper respiratory tract infection presenting various clinical manifestations in adults thereby likely making misdiagnosis and to put forth the patients with the symptom of acute abdominal pain as examples in order to caution emergency physicians to avoid misdiagnosis and mistreatment.Methods Data of 58 adult patients with upper respiratory tract infection were collected from January 2010 to December 2011.The chief complain of these patients was acute abdominal pain.After analysis of data including clinical history,symptoms and signs,laboratory findings and medication,patients were divided into two groups post hoc:correctly diagnosed group (group A) and misdiagnosed group (group B).In group A,anti-chill medicine such as tylenol cold tablets (a compositus of paracetamol,pseudoephedrine hydrochloride,dextromethorphan and chlorpheniramine) was given to patients,while in group B,anisodamine (muscarine cholinergic blocker) and antibiotics were given instead of anti-chill medicine.The anti-chill medicine such as tylenol cold tablets would be given to patients of group B when abdominal pain was not released 8-48 hours after treatment.The course of treatment and outcome of patients in the two groups were observed.Results Of 28 patients in group A,27 had abdominal pain relieved or disappeared 2-3 hours after treatment and only 1 patient had abdominal pain lasted 12 hours after treatment.Of 30 patients in the group B,only 2 patients presenting the symptom of acute gastroenteritis got totally relived 2-3 hours after treatment,while the rest of 28 patients did not get rid of abdominal pain,or only had brief period of painlessness after anisodamine injection.Alternatively,8-48 hours later as Tylenol Cold Tablets was given to patients of group B,the abdominal pain was relieved or disappeared after 2-3 hours without recurrence in 2-48 hours.Conclusions Upper respiratory tract infection manifests diversely in adults,and acute abdominal pain could be a main clinical manifestation.Anti-chill medicine,such as tylenol cold tablets,has a noticeably therapeutic effect for acute abdominal pain caused by upper respiratory tract infection in adults,while anisodamine injection makes poor efficacy.

Objective To analyze right ventrieular diastolic dysfunction in essential hypertension by quantitative tissue velocity imaging(QTVI). Methods Twenty normotensives and forty-five hypertensives underwent standard Doppler echocardiography and QTVI of right ventricular lateral tricuspid annulus. By QTVI,diastolic measurements were obtained. According to WHO standard, the patients with hypertension were classified into three groups, grade Ⅰ (group Ⅰ) 15 cases, grade Ⅱ(group Ⅱ) 15 cases, grade Ⅲ (group Ⅲ) 15 cases. Results Pulsed Doppler eehocardiography showed impaired Doppler diastolic indexes in hypertensives, without changes among the eases groups. In all hypertension groups, QTVI showed reduction of right ventricular Ea, increase of Aa and Ea/Aa<1 comparison with controls. IVRT of Ⅱ, Ⅲgroups was longer than normal. Conclusions Right ventricular diastolic function with essential hypertension decreased according to the degree of staging. QTVI has a greater predictive value than conventional imaging, and is useful for evaluating right ventricular function in patients with essential hypertension.
