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.

Objective To explore the clinical manifestation,imaging features,histopathological classifications and treatment of primary orbital tumors.Methods Twenty-six cases with primary orbital tumors were retrospectively studied.Results All of 26 primary orbital tumor cases received surgical treatment.Sixteen primary orbital tumors cases were male and 10 cases were female.The mean age was 46 years (ranged from 15 to 72).The mean hospital stay was 13 d (ranged from 9 to 21).Among 26 primary orbital tumors cases,21 cases were benign tumors which included 11 cases of cavernous hemangioma,5 cases of inflammatory pseudotumor,3 cases of dermoid cyst,2 cases of venous angioma.Five cases were malignant tumors which included 4 cases of adenoid cystic carcinoma and 1 case of rhabdomyosarcoma.After operation,visual acuity improved in 9 cases,unchanged in 11 cases,decreased in 6 cases.The patients were followed up for 18-48 months (mean,25 months).There were 4 cases of malignant tumors recurrence after operation and received radical operation.While 2 patients were lost,the other 24 patients survived with tumor-free.Conclusions Surgical excision is the main and effective treatment for primary orbital tumors.To be very familiar with the imaging characteristics and local anatomy is the key for operation.Individualized treatment plan should be chosen based on clinical manifestation,imaging features and histopathological classifications.

Objective To assess the renal protective effects of triptolide treatment in type 2 diabetic rats and its possible mechanisms.Methods Wistar rats were randomized to receive following approach control (n=7),dia- betic model without treatment (n=7) and diabetic group treated with triptolide[200 ?g/(kg?d),n=7].Plasma glucose (PG),serum creatinine (Scr),total cholesterin (TC),triglyeride (TG),kidney mass (KM),index number of kidney hypertrophy (KM/body mass,KM/BM),and 24 hours urinary albumin (24 h UAL) were determined. The protein expression of monocyte chemoattractant protein-1 (MCP-1),osteopontin (OPN) and ED-1 in renal tissue were determined by immunohistochemical technique.The mRNA expressions of MCP-1 and OPN in kidney tissue were assessed by reverse transcription-polymerase chain reaction (RT-PCR).Results Elevated 24 h UAL was markedly attenuated by triptolide treatment [24 h UAL,triptolide:2.32?0.29 vs diabetic model group:3.89? 0.51 mg/mgCr,P

Objective: To compare supercritical CO 2 fluid extraction(SFE CO 2) with steam distillation(SD) in the chemical constituents and content of essential oil from Forsythia Suspensa. Method: GC MS combination was adopted. Results: Both the two methods shared the same main components as ? pinene, ? pinene and sabinene. Benzene methanol,4 [1 methylethyl] and Benzene methanol,2 [4 methylethyl] were extracted exclusively by SFE CO 2, Among two methods there is a good deal of similarity all the other components extracted. Furthermore, sabinene、transpinocarveol and shorten were the first obtained from the plant. Conclusion: The SFE CO 2 was superior to SD in raising yield and reducing extractive time. It is a good method in extracting the essential oils from Forsythia Suspensa.

To investigate the expression of vaginal IL-23 and its role in experimental murine vaginal candidiasis and its relationship with infection and immune status, immuno-competent (group A) and immuno-suppressed (group B) murine models of vaginal candidiasis were established in estrogen-treated mice. Non-estrogen-treated mice were used as controls (group C). The level of IL-23 p19 mRNA in murine vaginal tissue was determined by RT-PCR. Significantly increased levels of IL-23p19mRNA were observed on the 4th, the 7th and 14th day after inoculation in immuno-competent group when compared with that in control group (P<0.01, P<0.05). However, significant increase of IL-23 p19mRNA were only observed on the 7th day and the 14th day after inoculatuon in immuno-suppressed groups (P<0.05). On the 4th and 7th day, the levels of IL-23 p19mRNA were significantly increased in immuno-competent group than those in immuno-suppressed group (P <0.05). Local IL-23 may play a role in the pathogenesis of murine vaginal candidiasis and has a protective function during infection. Low vaginal IL-23 level may correlate with the increased susceptibility to Candida albicans in immuno-suppressed group.
