Primary hypertension is one of the common chronic diseases, as well as the key disease for prevention and treatment by traditional Chinese medicine (TCM). The authors searched and analyzed RCTs studies on primary hyper-tension treatment with acupuncture in the PubMed. It showed that primary hypertension treatment with acupuncture abroad had high quality methodologies. However, the deficiencies of TCM theories in the treatment plan in these studies were the same as RCTs of acupuncture treatment design of other diseases. It may due to the insufficiency of TCM knowledge and culture differences of researchers aboard. Besides, the small sample amount, various interven-tions, no blank control, and the using of 24-hour ambulatory blood pressure most of the time, may difficult to objec-tively evaluate the clinical effect of acupuncture. Therefore, our research team will carry out high quality RCT stud-ies under the guidance of TCM theories of meridians and syndrome differentiation to further discuss the specificity of acupoints.

Objective To explore the effect of in utero exposure to inlfammation on innate immune response in preterm infants. Methods Forty-seven premature infants with gestational age<35 weeks were recruited in this study. According to his-tological evidence of placental infection, all neonates were divided into intrauterine inlfammation positive group and negative group. Mononuclear cells and monocytes were isolated from umbilical cord blood, and were cultured in vitro in the presence or absence of LPS (100 ng/ml). The levels of interleukin 1β(IL-1β), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α) and interleukin 10 (IL-10) in cord blood plasma and monocyte cultural supernatants were measured by ELISA respectively. The level of IL-1β, TNF-α, IL-6 and IL-10 mRNA were detected by Real-time PCR. Expression of HLA-DR on surface of CD14+monocytes and ratio of CD3+CD4+/CD3+CD8+T was analyzed by lfow cytometry. Results (1) The level of cord plasma IL-6 in intrauterine inlfammation positive group was signiifcantly higher than in negative group. (P=0.02). (2) After stimulation of LPS, levels of IL-1β, IL-6, TNF-α, IL-10 in supernatants were increased signiifcantly, in consistence with their mRNA expression (P<0.05) in both groups. (3) Expression of HLA-DR on surface of monocytes was signiifcantly decreased after stimulation with LPS in intrauterine inlfammation positive group (P=0.012), but was signiifcantly increased in negative group (P=0.0305). Con-clusions In utero exposure to inlfammation does not suppress the response of monocytes to LPS in preterm neonates, but impairs the antigen presenting function in monocytes.

Methods The comprehensive control measures including infection source control and Oncomelania hupensis snail eradication were surveyed along the Xinglong River in Qianji?ang City. Results The prevalence of schistosomiasis was under control that was the human and cattle infection rates decreased by 53.77%and 100%respectively the snail area decreased by 26.9% the mean density of living snails decreased by 25.5%and no infected snails was found. Conclusions The comprehensive control measures along the Xinglong River are effective and the management and surveillance of snail environments still should be strengthened.

Objective To study the effects of semiconductor laser irradiation and high voltage static electric fields on small vessel damage in diabetic rats.Methods Fifty healthy male Wistar rats were randomly divided into two groups:8 rats in a normal group and 42 in a diabetic model group.The diabetic models were created by intrape- ritoneal injection of streptozocin.The diabetic model rats were randomly divided into four subgroups:a diabetes group,a semiconductor laser treatment group,a high voltage static electric field treatment group and a comprehensive treatment group receiving combined semiconductor laser and high voltage static electric field exposure.The rats in each treatment group were subjected to the corresponding intervention.After 20 days of treatment,the venous blood, kidney tissue and myocardium tissue of the rats were collected,and the concentrations of blood glucose,insulin,en- dothelin and tissue were detected.Results Compared with the normal group,a significant increase in blood glu- cose and endothelin was observed in the diabetic model group,along with significantly decreased blood insulin and significant small vessel endothelium proliferation in the kidney tissue.Compared with the diabetes group,endothelin levels were significantly lower in all 3 treatment groups,and blood insulin was also higher in the comprehensive treat- ment group.Conclusion There were severe abnormalities in blood glucose,insulin and endothelin as well as mild impairment of small vessel endothelium proliferation in the diabetic rats.Semiconductor laser and high voltage static electric field exposure have a role in treating and preventing these conditions in diabetic rats.

Objective To prepare lipid-coated ultrasound microbubbles containing 10-HCPT(HLM) and explore the antitumor effects on mice xenografed H22 solid tumor using the technique of ultrasound-mediated HLM destruction. Methods Sixty-four tumor-bearing mice were radomly divided into A and B groups. Each group was divided into four groups again and administered respectively by tail vein with HI.M, non-drug-loaded microbubbles,10-HCPT and saline once a day. Ultrasound irradiation was applied on the tumor sites immediately after injection. After 7 days of consecutive treatment, all mice in group A were sacrificed and the tumors were harvested to measure weights. The tumor inhibition rate was calculated by weights. The tumor microvessel density (MVD) was detected by immunohistochemical staining. The tumor growth curve was depicted according to volumes. The survival time of mice in group B was recorded. Results The tumor inhibition rate was the highest in HLM group while this group's MVD was the lowest. Survival time in HLM group and 10-HCPT group were obviously longer compared with the control group,while no statistic difference was observed between the two groups. There was no statistic difference between the group of non-drug-loaded microbubbles and the control group. Conclusions Ultrasound irradiation mediates HLM destruction so that the drug is released from the vihicles at the same time, which can significantly enhance the tumor inhibition effect of 10-HCPT on the H22 tumor. This technique is expected to be adopted as a novel tool for liver cancer chemotherapy.

Objective To evaluate the method of detecting antibodies to Bacillus anthracis by enzymelinked immunosorbent assay(ELISA)using crude antigen.Methods The anti-Bacillus anthracis antibody levels in sera of 42 healthy people and 42 patients were detected by indirect ELISA.Standard curve was plotted using the data from positive controls,based on which the relative content of each serum was calculated and compared with the result of rLF.Results The median of antibody's relative content in patient group and healthy people group are 1.19 and 0.24,the differences being statistically significant(uc=7.643,P＜0.05).The result of crude antigen is in concordance with rLF(but not parallel absolutely).Conclusions Crude antigen can distinguish most of patients with healthy population effectively.The results suggested that crude antigen is applicable in anti-Bacillus anthracis antibody surveillance.
