Objective To investigate the effects of different concentrations of isoflurane on neuronal apoptosis in hippocampus and cerebral cortex in the aged rats. Methods Ninety female pathogen-free SD rats 22-24 months old weighing 497-593 g were randomly divided into 3 groups: group Ⅰ oxygen group inhaled air enriched with 40% O2,groupⅡ and Ⅲ were anesthetized with 1.2% and 1.8% isoflurane for 3 h respectively. Morris water maze was used to assess the cognitive function. The animals were killed at 24 and 72 h and on the 7th day after emergence from anesthesia and their brains were removed. Neuronal apoptosis in hippocampus and cerebral cortex was detected by TUNEL. Results The average escape latency was significantly longer on the 2nd and 3rd day after isoflurane anesthesia in isoflurane group than in oxygen group (P < 0.05 ). The neuronal apoptesis rate was significantly higher in the 2 isoflurane group than in oxygen group (P < 0.05 or 0.01 ). Conclusion Isoflurane anesthesia can result in transient cognitive dysfunction, and the mechanism may be involved in apoptosis in cerebral cortex in the aged rats.

Objective To evaluate the clinical value of selective salpingography(SSG)and fallopian tube recanalization(FTR) for diagnosis and treatment of oviduct obstructive infertility with self-made simple coaxial microtube.MethodsSSG and FTR with self-made simple Coaxial Microtube were performed for 76 cases with 134 tubes of obstructive oviduct through wire-guided tubal recanalization,anti-inflammatory and anti-adhesion effect of recanalization fluid,and the patients were treated with anti-bacterial and hydrotubation after operations.ResultsSSG displayed that 81 tubes obstruction in interstitial tubal,25 tubes obstruction in isthmus,16 tubes obstruction in ampulla and 12 tubes obstruction in fimbria.The total recanalization rate of FTR was 76.1%,with the recanalization rate 96.3% in interstitial,the recanalization rate 68.0% in isthmus and the recanalization rate 43.8% in ampulla,and no serious complications occurred.All cases were followed up for one to two years postoperatively.Normal pregnancy pationes were 31 cases(40.8%),and 29 women were normal parturition,2 cases(2.6%) were extrauterine pregnancy.ConclusionThe advantage of SSG and FTR with self-made simple coaxial microtube is low cost,simplicity and excellent efficacy.It is worth popularizing in grass-roots hospitals.

This article discusses the ethical problems which appear when medical laboratory technicians deal with all kinds of interpersonal relations in the field of medicine from the point of present medical service.It advocates that medical staff should possess professional morality and the sense of duty and calls for humane spirits to set up a brand-new mode of medical ethics.

In addition to the structural genes of the coronavirus genome, S, E, M, and N, there are several additional genes called "group-specific or accessory genes". Their gene products are designated as "accessory proteins", as reports to date make it clear that these proteins are not essential for virus replication in vitro. Nevertheless, many of these genes are still maintained in the virus genome under selective pressure, suggesting that they might play a very important role in the survival of the virus in the natural environment of the infected host. This review will summarize the research progress in the functions of coronavirus accessory genes.
