Objective To observe the clinical efficacy of acupuncture and miuci therapy combined with Qinggan Tongqiao Decoction for sudden sensor-neural hearing loss (SSHL) and the effects on level of plasma endothelin (ET) and serum nitrate oxide (NO). Methods Totally 110 patients with SSHL were randomly divided into treatment group and control group, with 55 patients in each group. The control group was given Qinggan Tongqiao Decoction combined with acupuncture routine treatment, and treatment group was given miuci therapy on the basis of the control group, two weeks as a course of two groups. Level changes of plasma ET and serum NO, and pure tone listening threshold changes before and after treatment were observed. Tinnitus and hearing efficacy was evaluated. Results The total effective rate for tinnitus efficacy was 94.54% (52/55) in the treatment group and 85.45% (47/55) in the control group, with statistical significance (u=2.038, P=0.040). The total effective rate for hearing efficacy was 96.46%(53/55) in the treatment group and 81.82% (45/55) in the control group, with statistical significance (u=2.913, P=0.040). Compared with before treatment, the level of plasma ET decreased and the level of serum NO increased after the treatment (P<0.05); After the treatment, the level of plasma ET in the treatment was lower than the control group, and the level of serum NO in the treatment group was higher than the control group (P<0.05). Pure tone threshold scores in the two groups on treatment 3, 7, 14 d were significantly improved (P<0.05), and pure tone threshold scores in the treatment group were significantly lower than the control group (P<0.05). Conclusion Acupuncture and miuci therapy combined with Qinggan Tongqiao Decoction can significantly reduce clinical symptoms and enhance the hearing level of SSHL patients. The mechanism mainly lies in regulating levels of plasma ET and serum NO, and improving the inner ear micro-circulation.

Objective To compare the effects of ephedrine and dopamine in the prevention of hypotension during combined spinal and epidural anesthesia (CSEA)for cesarean delivery.Methods Fifty ASAⅠorⅡ patients undergoing elective cesarean delivery were randomly divided into the two groups,Ephedrine group (n=5 1 ):intrave-nous injection of 10mg ephedrine before anesthesia;Dopamine group(n=52):continuous intravenous infusion at the speed of 5μg·kg-1 ·min-1 .During the whole process,we investigated the incidence rate of adverse effects,com-pared the Apgar score of neonate and analyzed blood gas of umbilical artery and vein.Results Compare to the dopa-mine group,the incidence rate of hypotension was lower in the ephedrine group (43.1% vs 69.2%,χ2 =7.06,P=0.00).The pH value of umbilical artery and 1 min Apgar score of neonate in the ephedrine group was lower compare with that in the dopamine group[(7.22 ±0.03)vs (7.27 ±0.06),t=0.62,P=0.02],there are no significant difference of 5 min Apgar score in the two groups.Conclusion Compared with dopamine,ephedrine is a useful drug in the prevention of hypotension during combined spinal and epidural anesthesia (CSEA)for cesarean delivery and there are no significant differences of adverse effects of dopamine and ephedrine.Ephedrine has transient effect on the neonate,while the effect of dopamine is minor.

Lipoxins, metabolites of arachidonic acid , are a strong“braking signal” towards inflammatory reac-tion.Due to their anti-inflammatory and pro-resolving properties , lipoxins have emerged to be the central targets in the re-search on inflammation .The present article reviews the research advances of synthesis , biological effects and the protective role of lipoxins in the diseases of liver , pancreas , stomach and colorectum , thus providing a novel approach for the treat-ment of digestive diseases .

OBJECTIVE:To offer references for clinical rational use of Chinese patent drugs. METHODS:The basic theory of Chinese medicine was applied to analyze the current common problems encountered by western medicine physicians in the use of Chinese patent drugs. RESULTS & CONCLUSION:In the clinical use of Chinese patent drugs, the western medicine physicians should give consideration of the specific condition and get a detailed knowledge of drug constituents and the related clinical data as well as strictly follow the specification of drug package inserts.

Objective To explore the molecule mechanism of protective effects of transfecting human elafin gene recombinant plasmid to NCI-H292.Methods Constructe eukaryotic expression vector pEGFP-C1-elafin and transfectied it into NCI-H292 cells,then co-incubated with polymorphonuclear granulocyte(PMN) with stimulation by lipopolysaccharide(LPS).Afater 24 hour,Western bolt and MTT technique were respectively performed to detect expression of ZO-1 in cells and adhesion capability of cells with collagen.Results After stimulation with LPS,Western blot showed that the 220 ku onula occludens-1(ZO-1) protein in transfecting pEGFP-C1 NCI-H292 cells extracts were obviously decreased,in transfecting pEGFP-C1-elafin NCI-H292 cells extracts.And MTT technique showed that compared with transfecting pEGFP-C1-elafin cells,adhesion capability of transfecting pEGFP-C1 cells with collagen were obviously decreased.Conclusion Transfection of recombinant human elafin gene into airway epithelial cells could maintain airway epithelium and enhance the capability of airway to inflammatory injury.

Objective To explore the effects of miR-449a on the proliferation and apoptosis in human neuroblastoma SH-SY5Y cells.Methods Transferred miR-449a mimics SH-SY5Y cells by LipofectamineTM2000 as experimental group.Cell growth was measured by CCK8 assay,the cell cycle and apoptosis were detected by flow cytometry.Relative expression of c-Myc and Bax/Bcl-2 was detected by Western blot.Results Compare to blank and negative control cells,the proliferation of miR-449a mimics SH-SY5Y cells was decreased(P<0.05).Flow cytometry showed that over-expressed miR-449a resulted in an increase of G0/G1 phase and apoptotic cells.The expression of c-Myc showed significant difference (P<0.05),Expression of pro-apoptotic protein Bax was increased,and that of anti-apoptotic protein Bcl-2 was decreased(P<0.05).Conclusions miR-449a over-expression can inhibit cell proliferation by regulating cell cycles and induce apoptosis mainly through regulating Bcl-2 family proteins expression in SH-SY5Y cells.
