Objective To study the influence of Chiamydia trachmatis (CT) and Ureaplasma ure-alyticum (UU) infection on pregnant outcome and neonates. Methods 562 pregnant women were ran-domly selected, their cervical secretion was collected and detected for CT and UU by culture method. Groups were divided according to the results. All of them were followed-up till delivery. Results The in-cidence of infection of group CT、group UU、group CT and UU were 22.1%、28.8% and 3.7%;Compared with negative group,the group with positive result of CT、UU、 CT and UU had significant higher incidence of preterm labor, premature rupture of membranes, low weight infant and neonates pneumonia. Conclusions The infection of CT、UU can result in adverse pregnant outcome, preterm labor, premature rupture of mem-branes, low weight infant and neonate pneumonia.

Objective To assess the effectiveness of free distributing antipsychotics to the poverty schizophrenics.Methods 116 non-acute poverty schizophrenics were given free antipsychotics and their status were evaluated by Brief Psychiatric Rating Scale (BPRS) before and after administration of antipsychotics.Results The BPRS scores of schizophrenics decreased linearly with time （ P<0.05） during 4 months follow-up study.Conclusion Poverty schizophrenics acquire good therapeutic efficacy after accepting free antipsychotics, and the government should provide the poverty mental disorder patients with related policy and fund support.

This study was aimed to observe influence on clinical symptoms of Qing-Fei Pei-Yuan Wei-Wan (QFPY-WW) for pulmonary infection HIV/AIDS cases with the syndrome of phlegm-heat obstructing the lung. A total of 141 pulmonary infection HIV/AIDS cases with the syndrome of phlegm-heat obstructing the lung were randomly divided into the treatment group (94 cases) and the control group (47 cases). The treatment group was given basic western medication combined with QFPYWW. The control group was given basic western medication. After 4 weeks treat-ment, observation was made on changes of main symptoms. The results showed that on the 28th day, compared with the control group, there was improvement on symptoms such as cough, breathing and chest tightness (P< 0.05). Com-parison on coughing up phlegm degree showed that the treatment group was significantly better than the control group (P< 0.05). On the 7th day treatment, the treatment group had better effect on lowering body temperature than the control group (P< 0.05). It was concluded that QFPYWW can improve symptoms such as cough, breathing, chest tightness and cough up phlegm among pulmonary infection HIV/AIDS patients.

Objective To investigate the role of mitochondrial apoptotic pathway in intrathecal doxepin?induced apoptosis in rat neurons. Methods Twenty?four adult male Wistar rats, weighing 250-300 g, in which intrathecal catheters were successfully implanted without complications, were randomly divided into 4 groups ( n=6 each) using a random number table: control group ( group C) and different concentrations of doxepin groups (D5, D10 and D20 groups). In D5, D10 and D20 groups, 5, 10, and 20 mmol∕L doxepin 0. 2 μl∕g were injected intrathecally, respectively. In group C, the equal volume of normal saline was given instead. At 6 h after intrathecal administration, the animals were sacrificed, and the lumbar segments of the spinal cords were obtained for detection of the cell apoptosis ( by TUNEL assay) , expression of Bax and Bcl?2 ( by immunohistochemistry) , release of cytochrome c ( Cyt c) , and expression of caspase?3, caspase?8 and caspase?9 mRNA ( using real?time reverse transcriptase polymerase chain reaction) . Apoptosis rate and Bcl?2∕Bax ratio were calculated. Results Compared with group C, the expression of Bax was significantly up?regulated, the expression of Bcl?2 was down?regulated, Bcl?2∕Bax ratio was decreased, the release of Cyt c and apoptosis rate were increased, and the expression of caspase?3 and caspase?9 mRNA was up?regulated in D10 and D20 groups, the expression of Bcl?2 was down?regulated in group D20 ( P<0.05 or 0.01) , and no significant change was found in the parameters mentioned above in group D5 (P>0.05). The expression of Bax was significantly up?regulated, Bcl?2∕Bax ratio was decreased, the release of Cyt c and apoptosis rate were increased, and the expression of caspase?3 and caspase?9 mRNA was up?regulated in D10 and D20 groups, and the expression of Bcl?2 was down?regulated in group D20 as compared with group D5 ( P<0.05 or 0.01) , and in group D20 as compared with group D10 ( P<0.05) . There was no significant difference in the expression of caspase?8 mRNA among the four groups ( P>0.05) . Conclusion Mitochondrial apoptotic pathways, but not death receptor pathway, is involved in intrathecal doxepin?induced apoptosis in rat neurons.
