To compare the effects of laparoscopic total or subtotal hysterectomy and myomectomy on ovarian reserve by measuring the serum level of anti-Mullerian hormone (AMH).A total of 96 patients with uterine fibroids underwent total laparoscopic hysterectomy (TLH group,n =32),laparoscopic subtotal hysterectomy (LSH group,n =31) and laparoscopic myomectomy (LM group,n =33).Changes in ovarian reserve were examined by measuring the level of AMH pre-operation and at 1 and 4 months post-operation.No significant differences existed in AMH in LM group[(1.42 ±0.65),(1.31 ±0.53) & (1.33 ±0.61) μg/L,P ＞ 0.05].The levels of AMH in both groups were significantly lower than those at pre-operation [(1.17 ± 0.11),(1.01 ±0.10),(0.48±0.54) & (1.18±0.93),(0.45 ±0.39),(0.14±0.0) μg/L,P＜0.001].The mean percentage decrease in AMH was lower in TLH group than that in LSH group at 4-month follow-up [(-37.4 ± 37.6) ％ vs.(-27.0 ± 23.0) ％,P =0.017].The results showed that LM had no effect on ovarian reserve.Both LSH and TLH had adverse effects on ovarian reserve and TLH was more marked.

Chronic stress can induce hippocampus injury such as neuron loss, dendrite atrophy, but its mechanism and molecular basis remain unclear up to now. To understand the molecular mechanism on protein level and find the crucial proteins which correlated with chronic stress-induced injury, two-dimensional electrophoresis was applied to separate the hippocampal total proteins of control group and restraint stressed rats, then the differential expressed proteins were detected by image analysis and identified by matrix assisted laser desorption /ionization time of flight mass spectrometry (MALDI-TOF-MS) as well as database searching. Moreover, the 2-DE results were verified on the mRNA level by semi-quantitative RT-PCR. The hippocampal 2-DE map with high resolution and good reproducibility of control and stress group rats were obtained. Fourteen differentially expressed protein spots were detected and eleven proteins were successfully identified, most of these proteins were involved in the process of energy metabolism and signal transduction. These results provide a clue for elucidating the mechanism of chronic stress-induced hippocampal injury and are useful for elevating the adaptability to stress.

Mother-to-child transmission (MTCT) is a major route of transmission of syphilis,and may occur at any time during pregnancy.MTCT of syphilis can lead to many adverse pregnancy outcomes,seriously affects maternal and infant health,and has been a severe public health and social problem.The risk of MTCT of syphilis is associated with stage of syphilis in pregnancy,stage of pregnancy,receiving or not receiving treatment,and is especially high in patients with early syphilis.With the growth of incidence of syphilis,the prevention for MTCT of syphilis has been becoming more and more important.Screening for and early treatment of syphilis in pregnancy can effectively block MTCT of syphilis.To learn the epidemiology,route,risk,and associated factors of MTCT of syphilis will undoubtedly facilitate the development of strategies for syphilis prevention and control.

This paper is aim to investigate the pharmacokinetics and absolute bioavailability of neoline in Beagle dogs, and provide a theoretical basis for further study. Ethyl acetate was used for liquid-liquid extracting after 10% ammonia alkalizing. The method of UPLC-Q-TOF-MS was established for the determination of neoline plasma concentrations. Beagle dogs were orally or intravenously administered with neoline for pharmacokinetic and absolute bioavailability study. Good linear relationship of neoline was found over the range of 0.1-4 mg x L(-1) (R2 = 0.9982) and 2-100 microg x L(-1) (R2 = 0.9945). Intra-and inter-day precision, expressed as the relativestandard (RSD) were less than 5.0%. Accuracy, expressed as the relative error (RE) was within 90.0%-115%. The recovery of neoline in dog plasma was more than 80%. After 6 mg x kg(-1) for ig and 1 mg x kg(-1) for iv administration of neoline, the main pharmacokinetic parameters were analyzed with Winnonlin software. t(1/2) were (313.88 +/- 63.18), (236.33 +/- 229.84) min, and AUC(0-infinity) were (58,027.40 +/- 14,132.69), (473,578.02 +/- 82,333.08) min x microg x L(-1) for ig and iv administration respectively. The absolute bioavail ability was (73.15 +/- 10.29) %. The method of UPLC-Q-TOF-MS described in the report was sensitive, reliable and specific, and suitable for pharmacokinetic study of neoline in Beagle dog. The high absolute bioavailability of neoline in dog suggested good absorption of neline which was worth of further investigation.
