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 evaluate the effect of comprehensive control of schistosomiasis along the Xinglong River in Qianji?ang City so as to provide the evidence for improving schistosomiasis control. 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 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.

Objective To study the effects of amniotic epithelial cells conditioned medium on the differentiation of bone marrow stromal cells into neural cells. Methods Bone marrow stromal cells and amniotic epithelial cells were isolated and cultured in vitro,then the cell surface antigen was detected by flow cytometry and the expressions of nestin and ki67 were detected by immunofluorescence staining method.When the cells were co-cultured with amniotic epithelial cells conditioned medium,the morphological character of cells was observed by inverse phase-contrast microscope,and the expressions of NSE(neurone specific enolase),TH(tyrosine hydroxylase) and DAT(dopamine transporter) were detected by immunofluorescence staining method. Results Amniotic epithelial cells conditioned medium had obvious inductive effect on bone marrow stromal cell's neural differentiation.Conclusion The amniotic epithelial cells conditioned medium may have inductive effect neuron-like cell's differentiation and dopaminergic neuron-like cell's differentiation of bone marrow stromal cells in vitro.

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 observe the clinical efficacy of heat-sensitive moxibustion plus Western medicine in treating patients with diabetic peripheral neuropathy (DPN). Methods: A total of 70 patients with DPN were divided into an observation group and a control group by sealed envelope method combined with the random number table method, with 35 cases in each group. The control group was treated with routine medicine, and the observation group was treated with heat-sensitive moxibustion on the basis of the treatment in the control group. After 2 courses of treatment, the scores of Toronto clinical scoring system (TCSS) and vibration perception threshold (VPT) in both groups were observed, and the clinical efficacy was compared. Results: During treatment, 3 cases dropped out in the control group and 4 cases in the observation group. After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). The scores of TCSS and VPT in both groups decreased after treatment, and the intra-group comparison showed statistical significance (both P<0.05). The scores of TCSS and VPT in the observation group were lower than those in the control group, and the differences were statistically significant (both P<0.05). Conclusion: Heat-sensitive moxibustion plus Western medicine can improve the symptoms in patients with DPN, and has a better curative effect than the Western medicine alone.
