Objective: To observe the clinical effects of needling acupoints Shenting(GV 24),Neiguan(PC 6) and Sanyinjiao(SP 6) in the treatment of migraine. Methods: Thirty cases of Germen patients with migraine were treated mainly by Shenting(GV 24), bilateral Neiguan(PC 6) and Sanyinjiao(SP 6), as well as bilateral Hegu(LI 4) and Taichong(LR 3), Touwei(ST 8),Yangbai(GB 14), Cuanzhu(BL 2), Sizhukong(TE 23), Shuaigu(GB 8) and Sibai(ST 2) in the affected side of head, auricular Sympathetic (MA-AH 7), Er Shenmen (MA-TF 1), Heart (MA-IC) and Endocrine (MA-IC 3); another 28 cases were treated by routine acupuncture. The clinical results and immediate pain-relieving effects were observed. Results: The total effective rate was 90.0% in treatment group and 75.0% in control group, χ2= 4.57, P ＜ 0.05; the 24-hour pain-relieving effects were obviously better in treatment group than that in control group, χ2 = 10.11, P＜ 0.01. Conclusion: Needling Shenting(GV 24), Neiguan (PC 6) and Sanyinjiao(SP 6) has better effects than routine acupuncture in the treatment of migraine.

BACKGROUND: Cecropins are a kind of micromolecule protein with antibacterial activity. Eukaryotic cell-expressed or artificially synthesized Cecropins is characterized by low efficiency and high cost. OBJECTIVE: To clone and express an antibacterial peptide gene of Musca domestica Cecropin A, and to identify recombinant expression product. METHODS: Mature Musca domestica Cecropin A encoding nucleotide sequence was searched from the GenBank and amplified by RT-PCR. The gene of Musca domestica Cecropin A was cloned into prokaryotic expression vector pET32a and fused with gene of Thioredoxin (Trx) and expressed in E.coli BL2l (DE3). After induction by isopropyl-β-D-thiogalactoside, the sera of the immunized rabbits were collected after rabbits were immunized with the hemolymph of housefly larvae. Recombinant protein was identified by western blot analysis and N-[Tris(hydroxymethyl)methyl]glycine-sodium dodecylsulfate-polyacrylamide gel electrophoresis.RESULTS AND CONCLUSION: After induction by isopropyl-β-D-thiogalactoside, E.coli BL21 expressed mature Cecropin. Rabbit anti- housefly larvae sera, N-[Tris(hydroxymethyl)methyl]glycine-sodium dodecylsulfate-polyacrylamide gel electrophoresis and western blot analysis results confirmed that expression products were mature Cecropin. These suggest that prokaryotic expression system can be utilized to obtain natural mature Cecropin.

MicroRNA (miRNA) regulate the expression of target mRNA according to the specific base pairing. They are involved in proliferation,differentiation and apoptosis of cells. The expression of miRNA has distinct differences between normal tissues and cancers, miRNA can be oncogenes but also suppressor genes, they play an important role in cancer. And miRNA are promising to be a new therapeutic target. In this review, we will discuss the advance in the research of miRNA in cancer.

An analytical method of reversed phase high performance liquid chromatography (RP-HPLC) was developed for simultaneous determination of 5-hydroxymethylfurfural and nine phenolic compounds (including (+)-catechin, (-)-epicatechin, chlorogenic acid, rutin, caffeic acid, protocatechuic acid, syringic acid, ferulic acid and p-coumaric acid) in 20 min.Ten components were detected and separated successfully by Diamonsil C_(18) column (150 mm x4.6 mm, 5 μm) at wavelength of 280 nm and column temperature of 42 ℃, with acetonitrile and 3% acetic acid solution as the mobile phase in gradient elution.The resultant correlation coefficients of the ten compounds were between 0.9911 and 0.9995 with detection limit from 0.2 to 0.5 mg/L, the RSD less than 2.4% and the average recoveries from 89.4% to 98.3%.These experimental results demonstrate that 5-hydroxymethylfurfural and the nine phenolic compounds in different rice wine samples can be determined with the new method for practical uses.

In recent years,nano - materials have represented the superior biocompatibiliry and the arena of medical nano - materials have been extensively studied by various means all over the world. Is it possible that nano - bone implants overcome the existing limitations of the traditional bone implants for fusing operations in the future? State Food and Drug Administration (SFDA, CN) authorized the nano-bone implants- - nHA/ PA66 (YZB/0063 -2003) in 2005 but there were still lots of counterviews in this field. This review considers the advanced researches via comparing and analyzing the correlatire literatures recently.

OBJECTIVE To investigate the bacterial distribution and the extent of drug resistance in lower respiratory tract disease among aged people.METHODS From Jan 2006 to Dec 2006 we collected 304 sputum samples of the old patients who were diagnosed lower respiratory tract infection,bacterial distribution and antibiotic resistance of 178 strains of the pathogens were analyzed retrospectively.RESULTS The most common four kinds of Gram-negative bacilli were Pseudomonas aeruginosa,Klebsiella pneumoniae,Escherichia coli and Acinetobacter baumannii.For above bacteria,the ratio of the resistance to ampicillin,cefazolin and compound sulfamethoxazole was over 40%.The isolating rate of ESBLs-producing E.coli and K.pneumoniae was 29.8%.CONCLUSIONS Monitoring the common bacteria and ESBLs bacteria precisely can provide therapy,guide to early cure and control lower respiratory tract infection of aged patients effectively.

0.05).The splicing destruction among each group was the main breakage method between materials and fiber posts.The surface treatment of fiber posts with sandblast or hydrogen peroxide significantly enhanced the bond strength of the composite resin tested.The surface treatment of fiber posts with silane did not enhance the bond strength of the composite resin.

Objective: T o further investigate pathogenesis about vulvovaginal candi diasis (VVC). Methods: Human normal vaginal epithelial cells in vitro were cultured by tissue cultur e and keratinocyto serum-free medium. Passaging epithelial cells were coculture d with candida albicans medium in separate wells for 0, 3, 6, 12, 24, and 48 h. C ontr ol epithelial cells were cultured alone in separate wells. For examination o f cytokines and chemokines, at each time point, the coculture supernatant and th e control culture were collected. ELISA was applied to detect the levels of HBD -1, HBD-2 and SP-A protein expression in the vaginal epithelial cells (HBD-1 :F= 62.784,P=0.001; HBD-2: F=5127.984, P=0.000; F=542.210, P=0 .000). Also, we colle cted the vaginal doughing water of VVC patients and healthy women, and detected the levels of SP-A, then analysed the data. Results: In the tra il of human vagin al epithelial cells, in contrast to the control group, the medium group induced the epithelial cells to secrete more HBD-1, HBD-2 and SP-A at h48, which was co nsidered to be significant (P

Thirty-seven essential hypertensive patients were treated with nifedipine and captopril. The effects of both drugs on high blood pressure and inteacellular cations were reported.A significant reduction in leucocyte Na concentration compared to the baseline were noted after therapy (P
