This article was aimed to evaluate the efficacy of acupuncture and flunarizine for migraine treatment. Randomized controlled trials (RCTs) in migraine treatment by acupuncture andflunarizine were searched in the Pubmed, Cochrane Library, CNKI, VIP, and W anfang database. The quality of inclusion criteria were assessedaccording to the CochraneCollaboration's recommended methodand the effective data was extracted. Then, the RevMan5.2 software was used in thesummary and analysis of the effective literatures. The results showed thatthe total sample size was893 cases, with 10 studies according to the inclusion criteria. Meta-analysis showed that the short-term efficacy of the treatment group was higher than the control group [RR = 1.27, 95%CI (1.11, 1.45), P<0.000 4];the long-term efficacy of the treatment group was higher than the control group [RR = 1.76, 95%CI (1.05, 2.94), P=0.03]; headache degree of improvement was better than thecontrol group [MD = -2.00, 95%CI (-3.01, -0.99), P=0.000 1]. It was concluded that acupuncture was more effective than flunarizinein migraine treatment. However, the whole study sample size was relatively small, thequality assessment was not high, and the funnel plot analysis was left-right asymmetry, which indicated the presence of publication bias. It was concluded that more high-quality clinical cases should be confirmed in the future.

OBJECTIVETo verify the clinical efficacy on chronic fatigue syndrome of qi deficiency syndrome treated with acupuncture at selective time and explore the effect mechanism.

METHODSEighty patients were randomized into a selective-time-acupuncture group and an acupuncture group, 40 cases in each one. Qihai (CV 6), Guanyuan (CV 4), Hegu (LI 4), Taichong (LR 3), Sanyinjiao (SP 6) and Zusanli (ST 36) were selected in the two groups. In the selective-time-acupuncture group, acupuncture was used at 9:00am to 11:00am. In the acupuncture group, acupuncture was used at any time except in the range from 9:00am to 11:00am. No any manipulation was applied after the arrival of needling sensation. The treatment was given once every day, 10 day treatment made one session and two sessions of treatment were required. The fatigue scale was adopted to evaluate the efficacy before and after treatment in the patients of the two groups. The ratios among CD3+, CD4+ and CD8+ T cells in the peripheral blood were detected before ad b a after treatment.

RESULTSIn the acupuncture group, the total score of fatigue and the score of physical fatigue were reduced after treatment as compared with those before treatment (all P<0.05). In the selective-time -acupuncture group, the total score of fatigue, the s core of physical fatigue and the score of mental fatigue after treatment were reduced obviously as compared with those hefore treatment (all P<0. 01). The improvements in the scores of the selective-time-acupuncture group were superior to the acupuncture group (all P<0. 05). The ratio of CD3+ and CD8+ T cells was increased obviously after treatment in the two groups (all P<0. 05) and the ratio of CD4+ and CD8+ T cells was reduced obviously in the selective-time-acupuncture group (P<0. 05), which was better than that in the acupuncture group (all P<0.05). The total effective rate was 95.0% (38/40) in the selective-time-acupuncture group, which was better than 80.0% (32/40) in the acupuncture group (P<0.05).

CONCLUSIONThe acupuncture therapy at selective time is effective in the treatment of chronic fatigue syndrome of qi deficiency syndrome, which is especially better at relieving mental fatigue. The effect of this therapy is achieved probably by improving the immune function via the regulation of the ratios among CD3+, CD4+ and CD8+ T cells.

?AlM: To evaluate the long - term effects of laser peripheral iridectomy ( LPl ) and trabeculectomy in treating early chronic angle-closure glaucoma.
?METHODS: Ninety-eight patients (102 eyes) with early chronic primary angle-closure glaucoma were randomly divided into two groups. Group A of 50 patients (54 eyes) was treated with LPl and group B of 48 patients (48 eyes) with trabeculectomy. After 3 - 8y of follow - up observation, comparison would be made from the perspectives of postoperative eyesight, intraocular pressure, anterior chamber angle, visual field and cup/disc ratio ( C/D) .
?RESULTS:ln group A, 24 eyes with eyesight declining, 22 eyes with theintraocular pressure>21mmHg (1mmHg=0. 133kPa), 21 eyes with chamber angle synechia >180o, 21 eyes with visual field narrowed, 21 eyes with C/D ratio enlarged. The results of group B for the same items were 10, 5, 4, 4, 4 eyes respectively. The comparative difference was statistically significant (P<0. 05).
?CONCLUSlON:Good effects will be achieved for early-stage chronic angle - closure glaucoma with surgical method. Trabeculectomy is obviously better than LPl for the long-term effects.

To develop different methods for determining siRNA content and the entrapment efficiency of siRNA loaded liposomes, SYBR Gold electrophoresis method and Ribogreen fluorospectrophotometry method were used respectively. SYBR Gold electrophoresis method has a good linear relation in a range at 0.2-2.0 micromol x L(-1) (R = 0.9930), and the recovery at the high, middle and low concentrations were 96.35%, 96.92%, and 100.74%, respectively (n = 3). The intra-day and inter-day RSD were far below 5% (n = 5). Ribogreen fluorospectrophotometry method has a good linear relation in a range at 10-50 nmol x L(-1) (R = 0.9971), and the recovery at the high, middle and low concentrations were 98.22%, 99.88% and 99.64%, respectively (n = 3). The intra-day and inter-day RSD were far below 5% (n = 5). The content and the entrapment efficiency of three batches of siRNA cationic liposomes were 98.52%, 97.85% and 99.20%, 96.45%, respectively, with these two methods. And there is no significant difference by ANOVA. Both of the two methods are accurate, sensitive, convenient method for determination of the siRNA content and the entrapment efficiency of siRNA loaded cationic liposomes.

To observe the effect of Helicobacter pylori(H.priori) on cell gap junction ultrastructure of gastric epithelial cells,and to explore carcinogenic mechanism of H.priori from the changes of cell gap junction,BGC-823 cells were co-cultured with different H.prlori strains for 24 h and 48 h.The cell gap junction ultrastructure was observed under transmission electron microscope with sample preparation of fixation and embedding in situ.In 70 patients with gastric eancer(GC),H.priori was detected by rapid urease test,basic fuchsin stain and 14C-urea breath test.The CagA gene of H.prlori was determined by PCR and the cell gap junction ultrastructure was observed under transmission electron microscope.More cell gap junctions and junction complexes of BGC-823 cells were found in control group without H.priori.Groups with H.priori had less number of cell gap junctions,less number of junctions/unit perimeter,shorter length of junctions/unit perimeter,and bigger width of the intercellular space,comparing to control groups without H.priori(P＜ 0.001 or P＜ 0.005).The number of cell junctions and the number of junctions/unit perimeter in the groups co-cultured with NCTC J99,GC 01 and NCTC 11639(CagA+) were less than that in the groups co-cultured with NCTC 12908(CagA-)(P ＜0.001 or P＜0.05),and the length of junctions/unit perimeter in the groups co-cultured with NCTC J99 and GC 01 was shorter than that in the groups co-cultured with NCTC 12908 (P＜ 0.001).In patients with GC,the number of cell junctions,the number of junctions/unit perimeter and the length of junctions/unit perimeter in group H.priori infection were all less than those in group without H.prior/infection(P ＜0.001),and that in CagA+ H.prlori group were less than that in CagA- H.prlori group,but its smallest width of the intercellular space was longer than that in CagA- H.prlori group.The above results showed that the changes of cell gap junction of gastric epithelial cells were associated with H.prlori infection especially CagA+ H.prlori infection.

OBJECTIVETo investigate the clinical application of the ureteral dilation catheter combined with the balloon catheter under the ureteroscope in the treatment of urethral stricture in men.

METHODSUnder the ureteroscope, 45 male patients with urethral stricture received placement of a zebra guide wire through the strictured urethra into the bladder and then a ureteral dilation catheter along the guide wire, followed by dilation of the urethra from F8 initially to F14 and F16. Again, the ureteroscope was used to determine the length of the strictured urethra, its distance to the external urethral orifice, and whether it was normally located. An F24 balloon catheter and then a metal urethral calibrator was used for the dilation of the strictured urethra. After removal of the F18-F22 urethral catheter at 8 weeks, the urinary flow rate was measured immediately and again at 3 months.

RESULTSAll the operations were successfully performed without serious complications. The maximum urinary flow rate was (13.3-29.9) ml/s (mean [17.7 ± 3.2] ml/s) at the removal of the catheter and (15.2-30.8) ml/s (mean [19.8 ± 3.9] ml/s) at 3 months after it. Smooth urination was found in all the patients during the 6-24 months follow-up.

CONCLUSIONThe application of the ureteral dilation catheter combined with, the balloon catheter under the ureteroscope is a good option for the treatment of male urethral stricture for its advantages of uncomplicatedness, safety, effectiveness, few complications, less pain, high success rate, and repeatable operation.
