Objective To understand the status of human resources for AIDS control at city and county level in Hebei Province,and to improve the outfit of human resources.Methods General investigation and self-designed questionnaire were used by the trained investigators.Epi Data 3.0 was used to establish a database,and SPSS 13.0 was used to analyze the data.Results There were 1 347 missionaries at the city and county level,547 of whom were full-time staff.Significant differences existed in academic qualifications and titles between city and county level.A lack in technical staff in county level appeared.Conclusions The number of staff for HIV control in Hebei is not sufficient.Therefore human resources in these places should be strengthened and rationally allocated for AIDS control.

The objective of the present study was to establish a novel rapid fluorescence focus inhibition test (RFFIT GFP)for the detection of rabies virus antibody, in which a chimeric rabies virus expressing green fluorescent protein (HEP GFP) was used as the basic virus strain in RFFIT GFP assay, and a few serum samples from human, dog and cat were detected by this new method .The optimal serum dilution, virus dosage and infection time were determined in 24 serum samples from human, dog and cat by using RFFIT GFP, RFFIT and ELISA assays. The result showed that these 3 methods gave a good consistency. But RFFIT GFP was found to be more convenient and economic for the detection of rabies virus antibody.

This paper was aimed to study effects of diosgenin on expressions of activator protein-1 (AP-1) and vascular endothelial growth factor (VEGF) in synovial tissues of collagen-induced arthritis (CIA) rats induced by bovine type II collagen, in order to investigate the possible mechanism of herbal medicine diosgenin in the treatment of rheumatoid arthritis (RA). After the CIA rats models were successfully established, rats were randomly divided into the blank control group, CIA model group, diosgenin group, and positive medicine control (tripterygium) group. The in situ hybridization was used to detect the expressions of AP-1 (c-fos and c-jun) in synovial tissues of the knee joint. The real-time PCR was used to detect the VEGF mRNA expression in synovial tissues of rats’ knee joints. The results showed that c-jun and c-fos, VEGF mRNA expressions in synovial tissues of rats’ knee joints were obviously higher than that of the blank control group (P<0.01). After treatment of diosgenin and tripterygium, the expressions of c-jun and c-fos, VEGF mRNA were significantly reduced (P<0.01). It was concluded that diosgenin may regulate the expression of VEGF in synovial tissues through c-jun and c-fos of AP-1 in order to inhibit synovial angiogenesis for the treatment of RA.

Objective Previous studies regarding the effects of tamoxifen ( TAM) on the thin endometrium are rare .The aim of this study was to explore the effects of TAM on patients with thin endometrium undergoing frozen thawed embryo transfer ( FET ) . Methods One hundred and thirty three patients with thin endometri-um undergoing FET treatment were recruited from January 2014 to June 2016, who canceled embryo transfer ( ET) or after FET due to thin endometrium in natural cycle or hormone replacement therapy cycle .Patients were randomly divided into letrozole ( LE,n=72) group or tamoxifen (TAM,n=61) group.All of the patients started to have oral pills of Estradiol Valerate 4 mg/d on the third day of menstruating cycles , then 6mg/d on the eighth day ,after 10~12 days then having ultrasonic monitoring of endometrial thickness and blood estradiol (E2), progesterone levels, It′s called endometrial preparation for hormone replacement cycle .To letrozole, tamoxifen group,the way of endometrial preparation were as follows:patients started to have oral pills of LE 2.5mg/d,TAM 40 mg/d on the third day of menstruating cycles for 5 days, then having ultrasonic monitoring and used drug of human chorionic gonadotropic hormone ,It′s called HCG day .After the dominant follicle ovulation then took progesterone intramuscular injection 40 mg/d, oral progesterone 20 mg/d to change endometrium ,then to transplant cleavage embryos or blastocysts after taking 3 or 5 days of progesterone , It′s called embryo transplanting day .The way of TAM endometrium preparation was called TAM cycle .The general data , hormone levels and clinical out-come between two groups were analyzed . Results The serum estradiol level of LE group both on HCG and transfer day [(1193.80± 629.64)ng/L vs (2776.30±157.34)ng/L;(1195.90±820.30)ng/L vs (2129.40±1208.71) ng/L,P=0.000] were statistically lower, serum luteinizing hormone level were statistically higher than TAM group [(20.48±15.50)IU/L vs (10.59±8.34)IU/L,P<0.05];im-plantation rate of LE group were statistically lower than TAM (39.32%vs 45.83%,P=0.001).The endometrial thickness and serum E 2 and P levels in TAM cycles were significantly higher compared with those in hormone replacement therapy cycle [(8.49±1.36)mm vs (6.43±0.96)mm,P=0.018]. Conclusion Tam compared LE with patients of thin endometrium undergoing FET can increased en -dometrial thickness and improve implantation rate ,thus Providing a new solution to thin endometrium .

Objective To study the effects of medicated serum with total saponins from Rhizoma Dioscreae Nipponicae (RDN) on VEGF mRNA expression and AP-1 activity in rat synovial cell strain RSC-364 induced by IL-17 and TNF-α. To investigate the mechanism about total saponin from RDN inhibition of angiogenesis. Methods Medicated serum of total saponins from RDN and tripterygium (positive control) were prepared. Rat synovial cells RSC-364 were divided into four groups: the blank control,IL-17+TNF-α model,tripterygium medicated serum,and total saponins medicated serum groups. After one hour of incubation,all groups except for the blank control were incubated with both IL-17(10 μg·L-1 ) and TNF-α(10 μg·L-1 ) for 24 hours. VEGF mRNA expression in RSC-364 was detected by PrimeScriptTM real-time quantitative PCR (RT-PCR) detection kit,and the AP-1 DNA-binding activity was detected by electrophoretic mobility shift assay (EMSA). Results Compared with the control blank group,both of the VEGF mRNA expression and AP-1 activity in rat synovial cell strain RSC-364 induced by IL-17 and TNF-α increased remarkably (P<0. 05,P<0.01). The VEGF mRNA expression and AP-1 activity in tripterygium medicated serum group and total saponins medicated serum group were remarkably lower than those of the model control group (P<0.05). There was no significant difference between the two medicated serum groups. Conclusion Serum medicated with total saponins from RDN can remarkably decrease VEGF mRNA expression and AP-1 activity,indicating that the total saponins from RDN could influence VEGF secretion by inhibiting the AP-1 signal transduction pathway,VEGF is the key factor of angiogenesis,thereby to restrain angiogenesis.

Background:Although sustainable control since 1950s has achieved great successes,schistosomiasis japonica remains a major public health problem in China.Since 2004,a new integrated strategy was developed aiming to control the transmission of Schistosoma japonicum through the implementation of a package of interventions.To date,no systematic review or meta-analysis assessing the effectiveness of this new integrated strategy for schistosomiasis control in China has been published.We performed a PubMed-based bibliometric assessment of publications on the new integrated strategy for schistosomiasis japonica control in China,to understand the global transmissibility and sharing of the new integrated strategy.Methods:An in-depth bibliometric analysis of all publications on the new integrated strategy for schistosomiasis japonica control in China was performed through a PubMed search using the terms "schistosomiasis" and "China,"from January 1,2004 to August 31,2018.All titles and abstracts were read carefully,and the publications reporting the effectiveness,experiences,lessons,or problems of the new integrated strategy were included in the bibliometric analysis.Results:Overall,2,361 titles were screened,and 70 eligible publications were accessed for analyses,including 23 studies in English,published in 15 international journals,and 47 studies in Chinese with abstracts in English,published in 3 national journals.Chinese Journal of Schistosomiasis Control (Zhongguo Xue Xi Chong Bing Fang Zhi Za Zhi) published 60％ of the research output,Research articles (48.6％) and short reports (37.1％) were the dominant manuscript types.Furthermore,471 contributing authors from 277 affiliations across 9 countries produced these 70 publications.Conclusion:This is the first PubMed-based quantitative analysis of the research output of the new integrated strategy,and our data indicate a low global transmissibility of Chinese new integrated strategy.We therefore call for more research outputs of the new integrated strategy for schistosomiasis japonica control in China to be communicated through international platforms.

Objective To analyze the clinical manifestations of pulmonary fungal disease in patients with different pathogen infection and different immune states. Methods A retrospective analysis was carried out with the clinical data of 78 patients with pulmonary fungal disease who were treated in Fujian Provincial Hospital from June 2012 to June 2016. Results The identified pathogens included Cryptococcus (78.2％, 61/78), Aspergillus(17.9％, 14/78), Talaromyces marneffei, Mucor, and Trichosporon asahii (one each). Cryptococcus was mostly found in healthy individuals without underlying disease and Aspergillus largely infected those with underlying disease. Diabetes mellitus was the most common underlying disease. Pulmonary fungal infection was confirmed by pneumonectomy (41.0％, 32/78), CT-guided percutaneous transthoracic biopsy (43.6％, 34/78), transbronchial lung biopsy (14.1％, 11/78), or blood culture (1.3％, 1/78). Pulmonary cryptococcosis was often asymptomatic (47.5％, 29/61). Hemoptysis was only found in the patients with underlying disease. The patients with pulmonary aspergillosis showed higher prevalence of hemoptysis (57.1％, 8/14) than the patients with other pulmonary fungal diseases. Bronchoscopy usually gave negative finding in case of pulmonary cryptococcosis (77.8％, 14/18). Inflammatory exudation was the primary finding of pulmonary aspergillosis (6/10). Intraluminal necrosis and neoplasia were only found in the aspergillosis patients with underlying disease. The primary imaging findings in pulmonary cryptococcosis was nodule or mass (78.7％, 48/61). Halo sign and crescent sign were rarely found in pulmonary aspergillosis. Of the 78 patients, 45 (57.7％) patients received pharmacological therapy alone, 15 (19.2％) surgical treatment alone, and 18 (23.1％) received drugs in combination with surgery. Six patients died, 25 lost to follow-up, and 47 with stable disease. Conclusions The clinical characteristics of pulmonary fungal disease vary with the pathogen and the immune states of patients. Clinical symptoms and immune status of patients should be taken into account when making diagnosis of pulmonary fungal disease for the purpose to speculate the probable fungal pathogen and choose the most appropriate diagnostic tool.
