Schistosomiasis is a neglected tropical disease which is socioeconomically devastating and a significant cause of morbidity in endemic countries or regions. Some countries and regions have brought down the prevalence of schistosomiasis through positive prevention and control programs. However in the past few years with the social and economic development and globalization re?emergence and spread of schistosomiasis led to a growing concern that new endemic areas may occur. This article analyzes the epidemiological situation and the strategies to control schistosomiasis in China and African countries.

Objective To evaluate the effects of parecoxib sodium for preemptive analgesia in patients undergoing cerebral angiography. Methods Sixty patients undergoing cerebral angiography were divided into two groups by random digits table with 30 cases in each : group P and group F. Patients in group P received parecoxib sodium 40 mg 30 min before operation, while group F received fentanyl 1 μ g/kg 2 min before operation. The changes of hemodynamics were observed before operation (To), immediately right internal carotid artery angiography during operation (T1), immediately right vertebral artery angiography (T2),immediately left internal carotid artery angiography(T3), immediately left vertebral artery angiography(T4), 10min after operation (T5). The mean arterial pressure (MAP), heart rate (HR), pulse oxygen saturation (SpO2)and visual analogue score (VAS) were recorded at different times during the whole operation. Results There were no significantly differences on MAP, HR and VAS between group P and group F (P > 0.05 ). But the SpO2 at T1 ,T2,T3 in group F (0.94±0.03,0.95±0.02,0.95±0.02) were significantly lower than those in group P (0.98 ± 0.01,0.98 ± 0.02,0.98 ± 0.02 )(P<0.05 ), and 2 cases SpO2 < 0.90 at Ti. Conclusion Parecoxib sodium administered preemptively provides a nice analgesic effect in patients undergoing cerebral angiography, and is more safe than fentanyl.

Objective To investigate the temporal and spatial distribution of Schistosoma infection of population and its risk factors in Eastern Dongting Lake area in 2012 and 2014,so as to provide the reference for formulating effective intervention mea-sures. Methods Junshan District was selected as a study field in Eastern Dongting Lake area. The method of spatial autocorre-lation analysis was applied to analyze the change of spatial distribution of Schistosoma infection in Junshan District in 2012 and 2014. The spatial regression model was fitted to detect the risk factors for human infection. Results The livestock infection rate in 2013 was lower than that in 2011. The average infection rate of schistosome was reduced to 0.55%in 2014. The spatial auto-correlation existed on the distribution of schistosomiasis in Junshan District in both 2012 and 2014 and 4 high incidence villages were identified. The results of the spatial error model showed that the prevalence of human infection was positively correlated with the infection rate of the livestock and the area of the susceptible environment in 2012. The spatial lag model showed that the prevalence of human schistosomiasis was positively correlated with the area of the susceptible environment ,but not with the in-fection rate of livestock. Conclusion The measures involving grazing prohibition and phasing out cattle and sheep are remark-ably effective and should continue on the basis of the current spatial distribution of schistosomiasis in this area.

Objectives To construct a cDNA subtractive library of dermal papilla cells (DPCs) in anagen with suppression subtractive hybridization (SSH) and clone differentially expressed genes related to DPCs in anagen. Methods Total RNA was isolated from DPC of anagen and telogen follicles. Then ds cDNAs were synthesized in turn using SMART cDNA synthesis technique. After cDNAs from anagen and telogen follicle DPCs were hybridized with each other twice and underwent two rounds of nested PCR, PCR products were ligated with arms of T/A plasmid vectors to set up the subtractive library. Selected clones were verified by reverse Nothern blot and DNA sequencing, and the acquired sequences were analyzed for homology based on Genbank nucleotide database. Results cDNA subtractive library of DPCs in anagen follicle was set up successfully with high subtractive efficiency. Thirty-five genes were identified with 22 known functional genes and 13 unknown functional genes. Conclusions These results demonstrate the effectiveness and sensitivity of SSH in detecting differentially expressed genes from a small amount of clinical samples. Information about such alterations in gene expression might be useful for elucidating the genetic events in hair follicle growth regulation.

Objective: To explore the peri-operative treatment and 3 years post-operative outcome in patients with rheumatic mitral valve stenosis and small left ventricle. Methods: A total of 152 patients with rheumatic mitral valve stenosis and severe pulmonary hypertension were studied. According to left ventricular end diastolic index (LVEDI) value, the patients were divided into 2 groups: Small left ventricle (Small) group, the patients with LVEDI value≤60 mm, n=67 and Non-small left ventricle (Non-small) group, the patients with LVEDI value>60 mm,n=85. Peri-operative condition and follow-up parameters were compared between 2 groups. Results: Compared with Non-small group, Small group had increased pre-operative CVP, SPAP and decreased LVEDV, LVEDVI and RVEF at admission, all P<0.05. All patients had liver damage at admission, the indexes (except alkaline phosphatase) were higher in Small group than Non-small group, and the function was recovered prior operation by proper treatment. The immediate post-operative SPAP in Small group and Non-small group were (67.3.1±23.4) mmHg and (61.3±26.9) mmHg, P>0.05. There were 52 severe pulmonary hypertension patients received iloprost inhalation, their SPAP was decreased than non-inhalation patients at incision closing; SPAP was lower in Small group inhalation patients than Non-small group inhalation patients, all P<0.05. Post-operative LVEDVI was lower and SPAP was higher in Small group than Non-small group. At 3 years post-operation, LVEDVI, RVEF increased, NYHA classification decreased and 6MWT prolonged in both groups; while LVEDVI was lower and 6MWT was shorter in Small group than Non-small group, P<0.05. The median survival time at (3.7±1.6) years post-operation was shorter in Small group than Non-small group,P<0.05, while the mortality was similar between 2 groups (2.6% vs 2.0%),P>0.05. Conclusion: The patients with mitral valve stenosis and small left ventricle had the worse pre-operative condition and higher risk in surgery; peri-operative treatment could improve their cardiac and liver function, but they still had the shorter post-operative median survival time.

As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.
