Objective To study the protective effects of anisodamine (ADM) on ventilator-induced lung injury (VILI) in rats. Methods After anesthesia was induced and tracheostomy was performed, 36 healthy male Sprague-Dawley rats were randomly assigned into three groups: control group (group A, VT=8ml/kg); injury group (group B), in which the animals received mechanical ventilation with large tidal volume (VT=40ml/kg); and ADM protective group (group C), in which the animals received the same amount of tidal volume and same respiratory rate with mechanical ventilation as in group B, but were pre-treated with ADM (15mg/kg?iV) at 24h, 12h, 0h time points before ventilation. Arterial blood gases were measured every one hour, and neutrophils in bronchoalveolor lavage fluid (BALF) were counted. Wet to dry (W/D) weight ratio of left lung was determined, and the content of TNF-? and IL-1? in BALF and blood, malondialdehyde (MDA), superoxide dismutase (SOD) levels in the pulmonary tissue and blood were measured respectively. The histopathological changes in pulmonary tissues in the three groups were compared. Results The oxygenation index (PaO2/FiO2) of the animals in group B was significantly lower than that in group A and C, and the BALF neutrophil count was remarkably increased in group B. W/D value of group B was significantly higher than that of group A and C. The levels of TNF-?, IL-1? in BALF were remarkably increased in group B , but decreased in group C . MDA levels in pulmonary tissue and blood in group C were lower than that of group B, but SOD level in group C was significantly higher than that of group B. Histopathologic findings demonstrated there were more neutrophil infiltration and destructive change in the alveolar wall in group B than in other groups. Conclusion ADM appears to have obvious protective effects on VILI through anti-inflammation and antioxidation.

Objective To observe the effect of Zhuyun Capsule(Pregnant-promoting Capsule)on serum sex hormone and expres- sion of ovarian cytokine of polycystic ovary syndrome(PCOS)rats.Methods Progestogen plus human chorionic gonadotrophin (HCG)was adopted to make PCOS rat models.Totally 40 SD rats were randomized into control group,PCOS model group,Zhuyun Capsule group,and clomiphene citrate group with 10 in each.Radioimmune assay(RIA)was used to measure the sex hormone and immunohistochemical test was done to measure the expression of tumor necrosis factor-?(TNF-?)of ovarian tissue,insulin-like growth factors-1(IGF-1),and leukemia inhibitory factor(LIF)to analyze the relations among these factors.Results Zhuyun Capsule could reduce greatly serum testosterone(T)and luteinizing hormone(LH),decrease expression of TNF-?and IGF-1,but increase expres- sion of LIF.Conclusion Zhuyun Capsule could regulate endocrine function and expression of ovarian cytokine to improve gonad func- tions of PCOS rats and to promote the maturation of follicle and ovulation.

Objective To understand the current situation of dispensary setting and personnel of community health service centers in Pudong New District in Shanghai (hereinafter referred to as Pudong New District).Methods Questionnaire survey covering the 45 community health service centers in Pudong New District was used.Results 42 community health service centers were equipped with TCM dispensaries among the 45 total units (93.3%);12 of them adopted outsourcing mode (26.7%);the average area of community dispensary was (32.3 ± 17.3)m2;the average number of TCM practitioners was 3.5 ± 2.0 people.Conclusion Community health service centers need to increase the allocation area of TCM dispensary and improve qualification of TCM practitioners.
