Objective To investigate the effects of Shenfu injection ( SF,a Chinese herbal medicine preparation made of Codonopsis pilosula and Aconitum carmichaeli) on the cell apoptosis of focal cerebral ischemic-reperfusion injured rats and the expression of heme oxygenase-1 (HO-1). Methods Forty-two male Sprague-Dawley rats used for producing unilateral brain ischemia reperfusion model were randomly divided into three groups:sham operation group ( Sham group),ischemia reperfusion group ( IR group),and SF Injection group (SF group).The model of focal cerebral ischemia-reperfusion injury was induced by transient occlusion of middle cerebral artery (ischemia for 2 h,and reperfusion for 3,6 h respectively).In SF group,SF ( 10 mg/kg) was intraperitoneally injected duri(n)g reperfusion.Cell apoptosis rate in brain tissue was detected by the technique of Annexin-V-PI double staining and was counted in flow cytometer.Expression of HO-1 in brain was measured by RT-PCR,while the pathological and ultra structure changes of cerebral tissue were also observed.Results Cell apoptosis rate of brain tissue were significantly higher in IR group than that in Sham group (P ＜0.01 ),while SF group had less significant changes in cell apoptosis rate, HO-1 level of brain tissue than IR group (P ＜ O.01 ).The ultra structure change of brain tissue was less in SF group than that in IR group.Conclusions During early stage of brain IR injury,SF inhibits cellular apoptosis and in turn protects the brain from injury which is attributed to the increase in HO-1 expression induced by SF.

OBJECTIVETo investigate the factors influencing the pregnancy outcomes of artificial insemination with donor sperm (AID), improve the pregnancy rate, and evaluate the safety of the offspring.

METHODSWe retrospectively analyzed 7,761 cycles of AID for 5,109 infertile couples performed between July 1, 2005 and June 30, 2013 in the Center of Reproductive Medicine of Shenyang No 204 Hospital, the outcomes of pregnancy, and the incidence of birth defects.

RESULTSTotally, 2 252 clinical pregnancies were achieved by AID, in which the pregnancy rate per cycle was 29. 02% and the cumulative pregnancy rate was 44. 08%. The clinical pregnancy rate was remarkably higher in the females of ≤ 35 years than in those of > 35 years old (30.31% vs 20.18%, P < 0.01), in the women with < 5-year infertility than in those with > 5-year infertility (30.83% vs 28.16%, P < 0.01), and in the patients of the ovarian stimulation group than in those of the natural cycle group (33.22% vs 28.68%, P < 0.01) The clinical pregnancy rate was the highest in the first treatment cycle (29.87%), with statistically significant difference from the fourth cycle (23.61%) (P < 0.05), but not between the other cycles (P > 0.05). There were 28 cases of birth defects in the offspring (1.40%), including 6 cases (21.43%) involving the cardiovascular system, 4 (14.29%) involving the musculoskeletal system, 3 (10.71%) involving the urogenital system, 3 (10.71%) involving the central nervous system, 2 cases (7.14%) of cleft lip and palate, 2 (7.14%) involving the respiratory system, 2 (7.14%) involving the gastrointestinal digestive system, and other anomalies.

CONCLUSIONFemale age, infertility duration, and ovarian stimulation treatment are important factors influencing the clinical pregnancy rate of AID. Artificial insemination with cryopreserved donor sperm does not increase the incidence of birth defects, which is considered as a relatively safe technique of assisted reproduction.

OBJECTIVETo compare the ability of osthole (OST) and genistein (GEN) in enhancing bone peak bone mass of rats to prevent osteoporosis.

METHODSThirty-six female one-month-old SD rats of (125 +/- 3) g body weight were randomly divided into three groups, 12 rats in each group, one group was orally administered osthole at 9 mg x kg(-1) d(-1), one group was given genistein at 10 mg x kg(-1) d(-1) and another was given equal quantity of distilled water as the control. The body weight was monitored weekly and the bone mineral density (BMD) of total body was measured every month. All rats were sacrificed after three months, the femoral bone mineral density, the serum levels of osteocalcin (OC) and anti-tartaric acid phosphatase 5b (TRACP 5b) were measured by Elisa. The bone microarchitectures were analyzed with micro-CT and the bone biomechanics properties were tested with universal material machine.

RESULTSNo significant differences were observed between O-treated or GEN group and the control for the food-intake and body weight during three months. However, the rats treated with OST had significant higher BMD for both total body and femur than the control and GEN group. The O-treated rats also had higher level of serum OC and lower level of TRACP 5b. Besides, they owned bigger bone volume/tissue volume, trabecular thickness, trabecular number but smaller trabecular spacing. In the three point bending tests of femurs,they were found to have larger maximum load, the young's modulus and structural model index (SMI).

CONCLUSIONOrally administered osthole could efficiently increase the peak bone mass of rats,which provide new ideas for preventing osteoporosis.

To study preliminarily the effect of Jiawei Bazhen decoction combined with oxytocin in promoting cervical ripening of full-term pregnancy women who were in the deficiency of qi and blood type through the syndrome differentiation of traditional Chinese medicine (TCM). 180 patients that met the inclusion criteria of the study were randomly divided into three groups: the control group(oxytocin group), the treatment group (Jiawei Bazhen decoction combined with oxytocin group), the blank control group (expected and observation group). Cervical maturity score (Bishop score), vaginal and cervical secretions fetal fibronectin (FFN), the result of induced labor, the result of mother and baby were observed in each group before and after treatment. The result comes out that the cervical Bishop score of pregnant women for treatment group were significantly higher than the control group and blank control group after treatment (P < 0.05). The FFN of pregnant women for the treatment group were significantly different from the control group and blank control group after treatment (P < 0.05). The pregnancy outcome of the three groups: the labor rate and rate of vaginal delivery of the treatment group were higher than the other two groups, and the difference was statistically significant (P < 0.05). The cesarean section rate of the treatment group was significantly lower than the other two groups, the difference was also statistically significant (P < 0.05). The three groups did not appear the phenomenon of neonatal asphyxia. Jiawei Bazhen decoction combined with oxytocin is effective in producing cervical ripening and induce labor. It is convenient, safe and reliable, for it is no obvious adverse effects on mother and fetus, but effective in reducing the rate of cesarean section, and playing a positive role in promoting natural delivery.

Objective To investigate the effects of naloxone (Na) on pneumocyte apoptosis and expression of heme oxygenase-1 (HO-1) during ischemia reperfusion injury of lung in rats. Method Forty-two male Sprague-Dawley rats were made models of ischemia reperfusion injury of unilateral lung, and were randomly( random number) divided into three groups: sham operation group (Sh group), ischemia reperfusion group (IR group) and naloxone group (Na group). The hilus of lung was clamped for 45 minutes and the clamp was taken off to build the I/R model. After 3-6 hours reperfusion, naloxone in dose of 1 mg/kg was injected intra-peritoneally in rats of Na group. The rate of cell apoptosis in lung tissue was detected with the way of Annexin-V-PI in flow cy-tometer. The wet to dry weight ratio (W/D) of lung tissue was measured. The expression of HO-1 in lung was measured by using RT-PCR and the ultra-structure change of lung tissue was observed under electron microscope. Results The rate of pneumocyte apoptosis and W/D ratio of lung tissue were significantly higher in IR group than in Sh group (P < 0.01), and the rate of pneumocyte apoptosis and W/D ratio of lung tissue were negatively correlated with the expression of HO-1 mRNA in lung tissue. Compared with IR group, the rate of cell apoptosis and W/D ratio were lower and the expression of HO-1 mRNA was higher in Na group (P < 0.01). The ultra- structure changes of lung tissue were lessened in Na group than in IR group. Conclusions During early period of lung IR injury, HO-1 induced by naloxone can inhibit the cellular apoptosis and protect the lung tissue.

OBJECTIVETo investigate how network education can improve college students' knowledge on sexual and reproductive health in Ningbo city.

METHODSFrom December 2012 to June 2013, we conducted a questionnaire investigation among college students in Ningbo city about the effects of network education on their knowledge about sexual psychology, sexual physiology, sexual ethics, and reproductive health.

RESULTSA total of 7 362 college students accomplished the investigation, of whom 2 483 (42.1% males and 57.9% females) received network education, while the other 4 879 (24.1% males and 75.9% females) did not. Approximately 47.1% of the male and 28.0% of the female students acquired sexual and reproductive knowledge via network education. Reproductive health-related network education significantly enriched the students' knowledge about the reproductive system and sex, pubertal development, sexual physiology, conception and embryonic development, methods of contraception, sexual psychology, sexually transmitted diseases and their prevention, pregnancy care and eugenics, and environment- and occupation-related reproductive health (P < 0.01). It also remarkably improved their cognitive attitude towards reproductive health knowledge (P < 0.01). Those who received reproductive health-related network education showed a significantly higher rate of masturbation (P < 0.01) but markedly later time of the first masturbation (P < 0.01) than those who did not.

CONCLUSIONNetwork education can enhance the effect of reproductive health education among college students and improve their sexual experience and health.

Humanin(HN,its analogue [Gly14]-Humanin,HNG)was originally identified as an endogenous peptide that protects neuronal cells from apoptosis induced by various types of Alzheimer's disease-related insults.But the relative low content of this peptide in its natural sources limits its further characterization.An expression vector pET32a/HNG was corstructed and transformed it into E.coli BL21 trxB(DE3).HNG was expressed as a fusion protein in the soluble fraction and was purified by nickel affinity chromatography.Subsequently,the purified fusion protein was cleaved by enterokinase and was further purified by reverse-phase HPLC.A 23 mg recombinant HNG(rHNG)from 1 L bacterial culture was purified.The molecular weight of rHNG determined by ESI-MS was 2876.5 Da which was the expected size for correctly processed peptide.The N-terminal amino acid sequence of rHNG determined by Edman degradation method is identical to the theoretical sequence.Neuroprotective bioassay studies of rHNG exhibited its potential neuroprotective effect comparable to that of the natural HNG peptide.
