AIM: To compare the efficacy and safety of bevacizumab with mitomycin ( MMC ) in augmenting trabeculectomy for glaucoma.
METHODS: Databases including PubMed, CBM, CNKI, VIP and WanFang Data were electronically searched for all randomized controlled trials ( RCTs) about comparing the efficacy and safety between bevacizumab and MMC in augmenting trabeculectomy for glaucoma before the date of Jun. 2016. Two reviewers independently screened literatures according to the inclusion and exclusion criteria, and evaluated the included studies. Then, Meta-analysis was performed.
RESULTS: A total 4 RCT involving 286 eyes ( 143 for bevacizumab group, 143 for MMC group) were included. The results of Meta-analysis showed that there was no significant difference between bevacizumab and MMC in the last follow-up after surgery in IOP (WMD=2. 21, 95%CI: -0.17 to 4.58, P=0.07), complete success rate (OR=0. 69, 95%CI:0. 26 to 1. 81, P=0. 45) and the numbers of anti-glaucoma medicine ( OR= 0. 12, 95%CI: -0. 15 to 0.39,P=0. 39). And there was no significant difference between bevacizumab and MMC in postoperative complications:hypotony (OR=0.7, 95%CI:0.12 to 4.05, P=0.69), bleb leak (OR=1, 95%CI: 0. 21 to 4. 74,P=1), encapsulated bleb (OR=1. 15, 95%CI: 0. 38 to 3. 44, P=0.81), choroidal detachment (OR=1. 22, 95%CI: 0. 29 to 5.22, P=0. 78) and cataract (OR=1. 15, 95%CI: 0. 38 to 3.44, P=0. 81).
CONCLUSION: Bevacizumab and MMC in augmenting trabeculectomy for glaucoma have similar efficacy and safety. Bevacizumab can't result in better outcome in term of IOP reduction. Clinicians should choose suitable solution according to disease characteristics.

This study was designed to validate the correlation between integrated pharmacokinetic and therapeutic effects of alkaloids using bile processed Rhizoma Coptidis (BRC). Rats were divided into three groups: normal, disease model, model+BRC. Rats were induced to have an excessive heat syndrome. Rectal temperatures were collected at 0, 3, 6 and 9 h after single oral administration of the drugs. The plasma concentrations of three alkaloids were quantified at different times by UPLC-MS/MS after the administration of BRC. An approach of self-defined weighting coefficiency was created to the holistic pharmacokinetic profiles of alkaloids in BRC. The classified and integrated synthetic concentrations were obtained, and then the pharmacokinetic parameters of alkaloids were calculated from non-compartmental model analysis. The potential relationship between the integrated mean concentration of alkaloids and the antifebrile efficacy was investigated. The holistic t(max) of alkaloids was 1.11 h, the antifebrile effect of BRC at 3 h was improved over the model group. Double peaking appeared in the integrated blood concentration-time curve, the second t(max) of alkaloids was 4.82 h. The antifebrile effects of BRC at 3-6 h were significant, and the antifebrile effects at 6-9 h was decreased significantly. Dynamic variation of alkaloids of BRC in the body exhibited the similarity to the pattern of its antifebrile effect.

Objective To observe the therapeutic efficacy of acupuncture at myofascial trigger points (MTrPs) in treating cervical spondylosis of vertebral artery type. Methods Ninety-eight patients with cervical spondylosis of vertebral artery type were randomized into a treatment group of 51 cases and a control group of 47 cases. The treatment group was intervened by acupuncture at the MTrPs, while the control group was by injection of medical solution for anti-inflammation and analgesia. The positive rate of rotate-cervix test, dizziness score, and visual analogue scale (VAS) of the head and neck pain were compared before and after intervention. Results After intervention, the positive rate, dizziness score, and VAS score were significantly changed in both groups (P＜0.05). There were significant differences in comparing the positive rate, dizziness score, and VAS score between the two groups after intervention (P＜0.05). The total effective rate was 96.1%in the treatment group versus 76.6%in the control group, and the difference was statistically significant (P＜0.05). Conclusion Acupuncture at the MTrPs can improve the dizziness and head-neck pain in patients with cervical spondylosis of vertebral artery type.

Objective To investigate the influence of different axial lengths (AL) on corneal curvature (CC),corneal astigmatism (CA),anterior chamber depth (ACD) and intraocular pressure (IOP) in age-related cataract.Methods Ocular data of 368 patients 368 eyes from Zhongnan Hospital of Wuhan University undergoing cataract surgery were retrospectively reviewed.AL,corneal curvature,corneal astigmatism and anterior chamber depth were measured using IOL-Master (Zeiss,German),and the intraocular pressure was measured using an iCare tonometer.Together 80 patients (80 eyes) selected from these patients with different AL using random number table were randomly divided into three groups,including short,moderate and long AL group.Spearman's rank test was used to assess the correlation between AL and ocular biological parameters.Each parameter was compared by one-way analysis of variance among the three groups,respectively.Results Spearman's rank test presented that AL was related with CC (r =-0.424,P ＜ 0.001),CA (r =0.138,P =0.008) and ACD (r =0.561,P ＜0.001),but there was no correlation of AL with IOP (r =0.064,P =0.326).The AL was negatively correlated with CC,positively correlated with CA and ACD,but there was weak correlation between AL and CA,as well as moderate correlation of AL with CC and ACD.The CC of the moderate and long AL group was significantly different from that of the short AL group (all P ＜ 0.001),but there was no significant difference between moderate and long AL group (P =0.438).Moreover,difference in CA was not statistical significant between short and moderate AL group (P =0.333) as well as between moderate and long AL group (P =0.718),but its difference approached statistical significance between short and long AL group (P =0.042).Pairwise comparison of ACD among the three groups had significant difference (all P≤0.001),but difference in IOP was not statistically significant with palrwise comparison (all P ＞ 0.05).Conclusion CC is negatively related to AL,and CA is weakly correlated to AL;meanwhile,it is possible to show that the degree of CA increases as AL gets longer.There is a moderate correlation between ACD and AL,while there is no relationship between AL and IOP.

BACKGROUND: Human granulocyte-macrophage colony stimulating factor (hGM-CSF) is a kind of cytokine which can stimulate the differentiation and proliferation of haematopoictic precursor cells and plays an important role in the process of immunoloregulation. Escherichia coli (E.coli) expression system has advantages,such as low cost and high output, over other systems.Therefore, E.coli is still the most commonly used exogenous gene expression system.OBJECTIVE: To observe the expression of hGM-CSF in the E.coli swain DH5α.DESIGN, TIME AND SETTING: The present observational experiment was performed at the Central Laboratory of Biotechnology Research,China Three Gorges University between February and June 2007. MATERIALS: Plasmid pBR322hGM-CSF was purchased from American Type Culture Collection, USA.hGM-CSF antibody was sourced from Sigma Company, USA.IPTG, X-gal,and vector pMGT-18 were purchased from Shanghai Bioengineering Technology Company, China. METHODS: Primer was designed according to hGM-CSF gene. Taking cloning vector plasmid pBR322-hGM-CSF as template, hGM-CSF gene was acquired and recombined into prokaryotic expression vector pGEX-4T-1. Recombinant plasmid confirmed by enzyme digestion and sequencing was transformed into E.coli strain DH5α and induced by isopropy-β-D-thiogalactoside (IPTG). Expression product was identified by sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE) and detected by Western blotting assay. MAIN OUTCOME MEASURES: hGM-CSF expression in the E.coli strain DH5α. RESULTS: SDS-PAGE results revealed that the recombinant hGM-CSF protein with relative molecular weight of 40 500 was produced up to approximately 17.9% of total protein. Western blotting detection results indicated that there was a 40 500 bp brand. CONCLUSION: The present study reconstructed prokaryotic expression vector pGEX-hGM-CSF, induced its expression in the E.coli strain DH5α, and obtained hGM-CSF fusion protein.
