Objective To investigate the comprehensive treatment of Crohn's disease complicated with anal fistula.Methods The clinical data of 33 patients with Crohn's disease complicated with anal fistula who were admitted to the Sixth Hospital of Sun Yat-Sen University from June 2007 to April 2011 were retrospectively analyzed.According to the range of the disease,surgical,medical and combined treatment were applied.Surgical treatment included thread-drawing drainage,fistulectomy,incision and drainage of the perianal abscess and enterostomy.Medical treatment include 5-aminosalicylic acid,immunosuppressive therapy,glucocorticoid,tumor necrosis factor monoclonal antibodies.All the patients were followed up till August 2012.The Crohn's disease activity index (CDAI) and perianal Crohn's disease activity index (PDAI) before and after treatment were analyzed using the independent sample t test.Results Of the 33 patients,22 received surgical and medical treatment,7 received surgical treatment,and 4 received medical treatment.The anal fistula was healed in 18 patients after the initial treatment (3 of them did not receive surgical treatment),and the mean closure time of the fistula was (3.2 ± 2.6) months (range,1-12 months) ; the condition of 8 patients was improved ; 4 patients suffered from fistula persistence ; anal fistula recurrence was observed in 6 patients,and the time for anal fistula recurrence was (35 ±56)months (range,5-148 months).The preoperative CDAI and PDAI of the 33 patients were 166 ± 100 (range,7-361) and 9.2 ± 2.6 (range,5-16),and the postoperative CDAI and PDAI of the 33 patients were 83 ± 53 (range,0-212) and 2.7 ± 3.1 (range,0-11).There were significant differences between the pre-and postoperative CDAI and PDAI (t =4.20,8.92,P ＜0.05).Of the 12 patients who were failed in the initial treatment,the anal fistula was healed in 3 patients after the treatment,and the condition of the other 9 patients remained the same.Of the 6 patients with anal fistula recurrence,5 received reoperation (4 were healed and 1 remained the same after the treatment) and the fistula of 1 patient who received medical treatment was not healed.At the end of the follow up,the anal fistulas of 20 patients were healed,and 10 remained the same.Conclusions There is no standard treatment for Crohn's disease complicated with anal fistula,surgical treatment combined with medical treatment is important for the treatment of Crohn's disease complicated with anal fistula.Surgical procedures should be chosen carefully according to the condition of the patients.

The operation performance of membrane nitrification bioreactor to treat ammonia-containing wastewater as well as the capabilities of separation and filtration of polypropylene membrane modules were tested. The removal efficiency of ammonia was kept higher than 95% when the hydraulic retention time was set at 1 day, the influent concentration was increased up to 80 mmol (NH4+ -N) x L(-1) and the volume loading rate was increased up to 1.12 kg (NH4+ -N) x m(-3) x d(-1). The biomass in the reactor was accumulated from 5 g x L(-1) to 10 g x L(-1) within 50 days, which indicated that polypropylene membrane modules were efficient in retaining biomass. The biomass attached to the membrane also contributed to the conversion of ammonia and nitrite. When the hydraulic pressure was lower than 80cm, the increase of hydraulic pressure improved the permeation of membrane. However, when the hydraulic pressure was beyond 80cm, the increase of hydraulic pressure did not significantly improve the permeation of membrane. The permeate flux was the highest 2.51 (L x m (-2) x h(-1)) but the resistance was the lowest (2.63 x 10(-5)) m(-1) when the hydraulic pressure was about 20 cm. The results showed that the membrane nitrification bioreactor could be run normally without extra energy input.

Objective To evaluate the efficacy and safety of olopatadine hydrochloride for the treatment of chronic idiopathic urticaria (CIU). Methods A multicentre, double-blind, randomized, parallel-group, controlled clinical trial was conducted. A total of 144 patients with CIU from 3 research centers were enrolled into this study, and randomly and equally divided into a test group and a control group. The test group administrated olopatadine hydrochloride 5 mg twice a day for 28 consecutive days, while the control group administrated levocetirizine hydrochloride 5 mg in the forenoon and a placebo tablet of olopatadine hydrochloride 5 mg in the afternoon for 28 consecutive days. The symptom score reducing index(SSRI)served as the primary outcome, and global assessment score for efficacy and total response rates as the secondary outcome. Results Totally, 137 patients completed the trial, including 70 in the test group and 67 in the control group. As intention-to-treat analysis showed, there were no significant differences in the total response rate between the test group and control group on day 7 (64.29% (45/70)vs. 56.72%(38/67), P > 0.05), 14(82.86%(58/70)vs. 74.63%(50/67), P > 0.05), or 28(87.14%(61/70)vs. 77.61%(52/67), P >0.05)after start of treatment. The SSRI was significantly higher in the test group than in the control group after 4 weeks of treatment(82.67% ± 22.70% vs. 70.51% ± 32.07%, P < 0.05). In addition, no significant difference was observed in the incidence of adverse reactions between the test group and control group(33.80%(24/71)vs. 27.94%(19/68), P > 0.05), and adverse reactions mainly included lethargy, dry mouth, fatigue, etc. Conclusion Olopatadine hydrochloride is effective and safe for the treatment of CIU.

Microbial contamination, growth and reproduction have a great influence on the quality of traditional Chinese medicine (TCM) and its preparation. TCM may be polluted by microbial in the production process due to ambient air, facilities and appliances and operating personnel, which affects the quality and efficacy of the final product. The GMP certification inspection standard of TCM manufacturing enterprises clearly established: "Sterilization methods of Chinese herbal medicine, intermediate products, finished products should follow the principle whether or not to change its quality", "TCM powder that used as medicine directly should follow the principle whether to do microbiological examinations". So it's particularly important for product quality, corporate energy consumption and its efficiency to choose the scientific and effective sterilization techniques and methods. Ozone is a kind of safe, environmentally friendly, efficient and no residue emerging sterilization technology. It has been widely applied in various fields of medical and health care and production and living. This paper mainly analyzed the ozone sterilization technology of TCM, aiming to explore the principle of ozone sterilization, the advantages, application status and existing problems and so on. The management regulations and implementation rules of ozone sterilization were summarized to make sterilization of Chinese medicine in the production, management, quality control and other aspects standardized, reasonable and scientific, and to provide the theoretical reference of the ozone sterilization technology for TCM and its preparation.

OBJECTIVETo explore the effect of electroporation mediated gene therapy on bone mineral density and strength of new-formed bone in mandibular distraction gap, so as to enhance the osteogenesis and shorten the distraction term.

METHODSNew-Zealand rabbits were employed. The distraction began after 3 days of latency period at the rate of 0. 8 mm per day for 7 days. After distraction, the rabbits were randomly divided into 5 groups to receive injection in the distraction gap with recombinant plasmid 2 microg (0.1 microg/microl) pIRES-hVEGF165-hBMP2 in group A, with recombinant plasmid pIRES-hBMP2 in group B, with recombinant plasmid pIRES-hVEGF165 in group C, with pIRES in group D, and with normal saline (NS) in group E. After injection, electroporation was performed in all the groups. After 1 week, 2 weeks, 4 weeks and 8 weeks of consolidation, all the animals underwent X-ray and quantitative computed tomography (QCT). The new-formed bone in distraction gap was selected as regions of interest (ROI) to measure the bone mineral density(BMD). Then the rabbits were sacrificed and the new-formed bone samples were harvested to detect 3-point crushing strength.

RESULTSBMD of newly formed bone in group A, B and C was markedly higher than that in group D and E (P < 0.01). After 2 weeks of consolidation, BMD in group A was much higher than that in the other groups, but there was no difference between group B and C. After 4 weeks of consolidation, BMD in group A and B was markedly higher than that in group C, D and E (P < 0.01). After 8 weeks of consolidation, BMD in group A was markedly higher than that in the other groups. While the BMD was not significantly different between group B and C, but the BMD in group B and C was higher than that in group D and E (P < 0.01). After 4 weeks of consolidation, the 3-point crushing strength of newly formed bone in group A was markedly higher than that in group B,C, D and E (P < 0.01), which was still the same after 8 weeks of consolidation. And the crushing strength in group B was higher than that in group C, D and E (P < 0. 05).

CONCLUSIONSElectroporation-mediated transfection of recombinant plasmid pIRES-hVEGF165-hBMP2 could greatly enhance osteogenesis and calcification. A combination of VEGF and BMP may promote osteogenesis and angiogenesis simultaneously, so as to magnify the effect of each growth factor, resulting a synergetic effect.

OBJECTIVETo investigate the potential differences in response to pegylated interferon (Peg-IFN) plus ribavirin (RBV) combination therapy in patients with hepatitis C virus (HCV) mono-infection and human immunodeficiency virus (HIV)/HCV co-infection.

METHODSSeventy HIV/HCV patients and sixty HCV patients, were administered a 48-week course of Peg-IFN + RBV. The HCV load was tested by the COBAS automatic viral load analysis system (lower limit of quantification = 15 IU/ml) at treatment weeks 0 (baseline), 4, 12, 24, and 48 and at week 24 after drug withdrawal. The patients were also genotyped by sequencing for the host-encoded interleukin (IL)-28B single nucleotide polymorphisms (SNPs) related to HCV Peg-IFN + RBV therapy outcome: rs8099917, rs12979860 and rs12980275. In addition, the HCV-encoded NS5B gene region was genotyped by nested-PCR and sequencing followed by BLAST searching of the Los Alamos National Laboratory HCV database. The significance of between-group differences in response to therapy and roles of SNPs were evaluated by statistical analyses.

RESULTSThe ratio of sustained virological response (SVR) was significantly lower in the HIV/HCV co-infected patients than the HCV mono-infected patients (32.9% vs. 71.7%; P less than 0.001). While the HIV/HCV co-infected patients did not show a significant difference in SVR ratio achieved between individuals infected with the HCV-1 genotype and the non-HCV-1 genotype (30.8% vs. 33.3%; P = 1.000), the HCV mono-infected patients did (86.1% vs. non 50.0%, P = 0.002). Moreover, the SVR ratio was higher in the HCV-1 genotype HCV mono-infected patients than in the HIV/HCV-1 genotype co-infected patents (30.8% vs. 86.1%; P less than 0.001). The different IL-28B genotypes were not significantly correlated to the PEG-IFN+RBV therapy response of either HCV mono-infected patients or HIV/HCV co-infected patients (P more than 0.05).

CONCLUSIONHCV mono-infected patients respond better to Peg-IFN + RBV therapy than HIV/HCV co-infected patients. The HCV-1 genotype may promote this therapy response in HCV mono-infected patients, but the IL-28B genotypes appear to play no significant role.

OBJECTIVE: To establish optimal amplification conditions with the application of 0.2 mL test tube in single cell separation and inspection. METHODS: Oral epithelium cell suspension was prepared. Five or ten cells were collected with 0.2 mL test tube. Then DNA were amplified with Identifiler Plus kit in three different conditions in which the proteinase K addition, gold enzyme concentration in PCR reaction, and PCR reaction cycles were adjusted separately. Finally the detection rate, allelic dropout rate and artificial alleles were compared among the groups. RESULTS: In these 3 different conditions: addition of proteinase K, addition of 0.4 microL gold enzyme in PCR reaction, and use of 32 cycles, the detection rate was higher and allelic dropout rate was lower than the other conditions. CONCLUSION In single cell separation and inspection, the usage of 0.2 mL test tube could be an effective supplement to chip-low volume amplification.
