OBJECTIVETo observe the clinical effects of essential hypertension treated with acupuncture at Siguan [Hegu (LI 4) and Taichong (LR 3)], Quchi (LI 11) and Xingjian (LR 2).

METHODSSixty cases of essential hypertension were randomly divided into an acupuncture group and a medication group, 30 cases in each group. Two groups of acupoint, which were (1) Siguan [Hegu (LI 4) and Taichong (LR 3)] and (2) Quchi (LI 11), Xingjian (LR 2), were selected alternatively in the acupuncture group, once everyday. In the medication group, captopril was prescribed for oral administration 25 mg per time, three times per day. Seven days made one session in both groups and totally three sessions were required.

RESULTS(1) After treatment, the blood pressure were decreased significantly in the two groups (all P < 0.01). Compared with the medication group, the diastolic pressure after 14 days, 21 days of treatment in the acupuncture group was decreased significantly (both P < 0.01). (2) In the terms of TCM syndrome score, the improvement of dizziness, soreness and weakness of waist and knees, palpitations was significant in the acupuncture group compared with that in the medication group(all P < 0.05). (3) The acupuncture group had less adverse reactions compared with the control group (P < 0.05).

CONCLUSIONAcupuncture at Hegu (LI4) and Taichong (LR 3), Quchi (LI 11) and Xingjian (LR 2) can effectively decrease blood pressure; the effect of controlling diastolic pressure is better than captopril. It can also improve the symptoms of dizziness, soreness and weakness of waist and knees, and palpitations.

Objective To investigate the effect of HIF-2a silencing by transfection of siRNA into MG-63 cells un-der hypoxia. Methods HIF-2αexpression level in MG-63 cells under hypoxia was determined by Western Blot. Small in-terfering RNA (siRNA) was used to construct MG-63/siHIF-2α(siHIF-2α)cells and control MG-63/scramble (NC) cells. The expression levels of HIF-2α, Vascular endothelial growth factor (VEGF), p-Erk/ErK and Mcl-1 in MG-63, NC and si-HIF-2αcells was determined by Western Blot. NC and siHIF-2αcells were cultured under hypoxia. Cell viability was as-sessed by MTT assay. Migration was identified by scratch migration assay. Tumor formation was identified by clone formation assay. Nude mouse subcutaneous xenograft model was used to investigate tumor development in vivo. Results Hypoxia im-proved HIF-2αexpression in MG-63 cells in a time-dependent manner (F=2 037.412,P<0.001). HIF-2αexpression un-der hypoxia in siHIF-2αcells was lower than that in NC cells (P<0.01). Cell viability of siHIF-2αcells under hypoxia for 12 h and 24 h were lower than that in NC cells (P<0.05 or P<0.01). The relative width of scratch in siHIF-2αgroup under hypoxia for 12 h and 24 h were larger than that in NC group (P<0.01 or P<0.01). When cell counts reach 1 000-5 000, the clone formation rates of siHIF-2αcells were lower than that in NC cells (P<0.05 or P<0.01). The expression of VEGF, p-Erk/Erk and Mcl-1 protein under hypoxia in siHIF-2αcells was lower than that in NC cells(P<0.01). Tumor sizes, weights and density of siHIF-2α group in nude mice were suppressed compared with those in NC group (P<0.01). Conclusion Blocking HIF-2αsignal pathway warrants its investigation as a potential strategy in osteosarcoma treatment.

Background Establising the culture model of Müller cells for obtaining the highly putified target cells is essential for the study about the physiology and pathology of retinal Müller cells. The exsiting purifing method for culturing Müller cells is dissatisfactory. Objective This study was to establish a method to obtain high purifing Müller cells. Methods The retina from 5 clean newborn SD rats were isolated and digested by 0. 01% trypsin and cultured in DMEM containing 10% fetal bovine serum. The cellular suspension was then prepared,and the target cells were screened using flow cytometry based on the size and the quantity of cells. Cultured and passaged cells were identified by transmission electron microscope and light microscope. Immunocytochemistry was used to detecte the expression of GFAP in cultured cells for the determination of type and purity of the cells. Results The cells showed the similar shape to retinal Müller cells after primarily culture with the large volume, and some small other types of cells could been seen. The growth of cells was quickly 3 weeks later. The fibroblasts were removed using sticking-wall by steps,and neurons were eliminated following passage. Aboundent of cellular organs were seen under the transmission electron microscope. The positive response rate of the cells for CFAP was 100%. Conclution Flow cytometry offer a rapid and feasible approach for purifying Muller cell and it builds the foundation for further study about Müller cells.

Objective To investigate the levels of immunoglobulins and complement in children with cerebral palsy. Methods 59 children with cerebral palsy were assessed with Gross Motor Function Classification System (GMFCS), and the serum levels of immunoglobulin (Ig)G, IgA, lgM, complements C3 and C4 were measured in the children with cerebral palsy and other 61 children without cerebral palsy (controls). Results The serum levels of IgG, IgA, lgM, complement C3 and C4 decreased significantly in the children with cerebral palsy compared with the controls (P<0.001). There was significant difference in the levels of IgG, IgM, and complement C4 among cerebral palsy children of different grades of GMFCS (P<0.05), but not in the levels of IgA and complement C3 (P>0.05). Conclusion There is humoral immune dysfunction in some children with cerebral palsy, which may associated with the severity of the disease.

Objective To study the epidemiological characteristics of the hip fractures of the inpatients so as to provide a scientific basis for strategic study on the prevention and treatment of the hip fractures. Methods The study involved 448 patients (217 males and 231 females) with hip fractures admitted to the Southwest Hospital of Third Military Medical University from January 2004 to December 2009. The characteristics, injury time and causes, fracture types and treatment approaches were collected and reviewed retrospectively. SPSS 13.0 software was used for statistical analysis. Results There were significant differences in distribution of the hip fractures in terms of age, cause, gender and treatment approach (P ＜ 0.05 ). Patients with age ≥60 years accounted for 68.8%. Slip was the leading cause of the hip fracture ( 69.6% ). As for gender distribution, femoral neck fractures usually occurred in the females while intertrochanteric hip fractures in the males. Surgery was the predominant management approaches,accounting for 83.1%. Conclusion The distribution of the hip fractures of the inpatients has unique characteristics in aspects of individual character, injury cause injury site and treatment approach, which is worthy of further strategic study on prevention and treatment of the hip fractures.

A method was developed for analyzing the stable carbon isotope ratio of five volatile components ( Ethanol, Glycerol, Acetic acid, Ethyl lactate, 2-methyl-butanol ) in wine using gas chromatography-combustion-isotope ratio mass spectrometer ( GC-C-IRMS ) . The sample injection volume was less than 0. 5 μL, and the analytical time of each run was less than 14 min. The precision of this method was 0. 08‰-0. 25‰ for analyzing standards, while 0. 09‰-0. 36‰ for wine samples. Compared to element analysis-isotope ratio mass spectrometry ( EA-IRMS) results, the deviations were lower than 0. 5‰. Fifty-four wine samples from France, Australia, America and China were considered. The δ13 C of five volatile components were measured using GC-C-IRMS. Discriminant analysis ( DA) was employed for analyzing the geographical origin traceability of selected wine. The result indicated that δ13 C of volatile components could be used to distinguish the origin of wines. The method was shown to be effective in improving detection of the origin traceability of wine.

Objective To analyze and compare efficacy and safety of different chemotherapy regimens in the treatment of elderly patients with advanced gastric cancer. Methods 60 elderly patients admitted to our hospital with advanced gastric cancer were selected as research subjects , and divided into experimental group and control group depending on the treatment of chemotherapy. The experimental group were treated with Gio oxaliplatin (SOX), and patients in the control group accepted Olivier Elizabeth, leucovorin and fluorouracil (FOLFOX6) treatment. Compare and analyze the efficacy of the two groups after two cycles of therapy. Results By chemotherapy, recent efficiency and disease control rate were not significantly different (P>0.05) between the two groups;and there was also no significant difference in the incidence of adverse reactions,such as adverse reactions, fatigue weakness, gastrointestinal reactions, hand-foot syndrome, oral mucositis (P > 0.05). Conclusion The efficacy was equivalent between FOLFOX6 chemotherapy SOX test group and the control group in the treatment of elderly patients with advanced gastric , and there was no significant difference in the incidence of adverse reactions.

Objective To evaluate the efficacy and feasibility of Flu/ivBu/Tl" conditioning regimen for the treatment of refractory or relapsed acute non-lymphocytic leukemia in patients receiving allogeneic hematopoietie stem cell transplantation. Methods Seven patients with refractory or relapsed acute non-lymphocytic leukemia received HLA identical peripheral blood hematopoietie stem cell transplantation (PBSCT) following Flu/ivBu/TY conditioning regimen, which consisted of fludarbine, busulfex and thiotepa. All patients received cyclos-porin A (CsA) and mycophenolet mofetil (MMF) for prophylaxis of graft - versus - host disease (GVHD). Results The Flu/IVBu/TT regimen was tolerated very well, without severe regimen related toxicity. In the 31-month median follow-up duration, 5 of 7 patients were a-live in disease-free situation. Conclusion The Flu/ivBu/TT conditioning regimen reduced transplantation-related toxicities and offered high long-term disease-free survival, and was tolerated very well. Allogeneie hematopoietie stem cell transplantation using Flu/ivBu/TT condition-ing regimen is a safe and effective option for the patients with refractory/relapsed acute non-lymphocytic leukemia.
