Objective:To investigate the effects of propofol on pyramidal neuron apoptosis in hippocampus of neonatal rats. Methods: Forty-twoseven-day-old male and female Sprague Dawley rats were randomly divided into three groups(n=14):group A received intraperitoneal 0.9% normal saline(7.5 ml/kg)once per day for seven days as control;group B received 0.9% normal saline(7.5 ml/kg)once per day for six days and propofol(75mg/kg)on the seventh day;group C received propofol(75 mg/kg)once per day for seven days. Two animals of each group were tested for blood glucose with tails cut off 3 hours after the last intraperitoneal injection,and six animals of each group were decapitated 5 hours after the last intraperitoneal injection for determination of caspase-3 expression with immuno-histochemistry. The other six animals of each group were decapitated after 3 weeks for microscopic examination. Results:Compared with group A,caspase-3 expression significantly increased while the number of pyramidal neurons decreased to different degree in both group B and C. More evident changes of the above were discovered in group C than that in group B,and the morphous of pyramidal neurons altered were only found in group C. Conclusion:The fact that increased caspase-3 expression leads to pyramidal neurons deletion to different degree was found in the rats which had received propofol.But the morphous ofpyramidal neurons altered onlywhen propofol had been repeatedlyinjected.

Microvessel density (MVD) is the gold standard to evaluate tumor angiogenesis. Contrastenhanced sonography has been developing fast in recent years. By measuring perfusion parameters, it can represent the degree of new angiogenesis of gynecologic malignant tumors indirectly, and evaluate the biobehavior and prognosis of tumor. The advances of correlations between contrast-enhanced sonographic appearance and MVD of gynecologic malignant tumors were reviewed.

This paper describes the development and challenge of HIV/AIDS testing laboratory network and quality assurance system in China. At present, the HIV/AIDS testing laboratories includes three classes, the National AIDS Reference Laboratory, HIV/AIDS confirmatory laboratories and HIV/AIDS screening laboratories. All of them are accredited by the health authorities, and each class of laboratories take charge of their function strictly according to the "National Management of HIV/AIDS Detection (2006)". A complete quality assurance and quality control system for HIV/AIDS testing has been developed, which includes technical training, strict laboratory monitoring and approval,examination or proficiency testing on HIV/AIDS detection, and quality evaluation and supervision of HIV/AIDS diagnostic kits. Besides conduct the routine anti-HIV antibody test, more and more laboratories began to conduct other tests, such as CD4+ T lymphocyte cell counting, HIV viral load, HIV DNA PCR, genotyping, drug resistance, and HIV-1 recent infection test. The primary challenges faced by the HIV/AIDS testing laboratory network are in the areas of laboratory management and quality control. For example, the provincial PT program is inefficient, the internal quality control is conducted perfunctorily, personnel training can not met the needs of the workplace, which need to be improved.

A clinically isolated syndrome(CIS) is a term that describes a first clinical episode in which a patient has symptoms and signs suggestive of an inflammatory demyelinating disorder of the central nervous system.And it often affects optic nerves,the brainstem,or the spinal cord,and 30％-70％ of the CIS patients may develop multiple sclerosis(MS).Disease-modifying treatments may delay the development from CIS to MS.Their use in CIS is limited because of uncertain long-term clinical prognosis,treatment benefits and adverse effects.This article reviews the advances of predictive markers of conversion to MS after a CIS,in order to provide the reference for clinical treatment.

Objective To observe the treatment of continuous passive motion(CPM) on talipes valgus in the chil-dren with cerebral palsy. Methods There were 57 children in this research including normal group and valgus group, the children in valgus group were randomly divided into control group, non-CPM group and CPM group. The control group didn’t receive any rehabilitation treatment. The non-CPM group received conventional rehabilita-tion treatment. The CPM group received conventional rehabilitation and CPM therapy. Evaluate the children in nor-mal group with plantar pressure analysis and evaluate each patient before treatment two and four months after treat-ment with plantar pressure analysis. Results Compared with the normal group, the percentage of medial midfoot (MMF) pressure, HEEL pressure, initial contact phase(ICP) and forefoot contact phase(FFCP) were obviously higher in valgus groups. On the other hand, the percentage of lateral forefoot ( LFF) pressure, lateral midfoot (LMF) pressure and foot flat phase(FFP) were obviously lower in valgus groups(P < 0. 05). The percentage of MMF pressure, and FFP became lower after treatment in both CPM group and non-CPM group while the percentage of ICP and FFCP became higher(P < 0. 05). In CPM group there was a more obvious change with the percentage of MMF pressure, ICP and FFCP compared with non-CPM group and the control group(P < 0. 05). Conclusion U-sing CPM can alleviate muscle spasms and contracture, correct the deformity of midfoot, enhance the muscle group coordination on foot and further more improve gait of patients with cerebral palsy.
