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.

In-vitro assay methods were established to evaluate transactivation and binding activity of compounds on peroxisome proliferator-activated receptor y (PPARγ). Firstly, plasmids were constructed for transactivation assay of PPARγ response element (PPRE) triggered reporter gene expression, and for cell-based binding activity assay of the chimeric receptor, which was fused with PPARγ ligand binding domain (LBD) and yeast transcriptional activator Gal4. Secondly, by using PPARy competitive binding assay based on time resolved-fluorescence resonance energy transfer (TR-FRET), affinities of compounds and drugs to PPARγ were evaluated. In application of these above methods, the PPARγ activating potency and characteristics of different compounds were evaluated, and a novel benzeneselfonamide derivative, ZLJ01, was found to have comparable binding activity and affinity with the well-known PPARy agonist, but lack of PPRE mediated transactivation activity. In preliminary study on in-vitro hypoglycemic activity, ZLJ1 was found to promote insulin-stimulated glucose uptake by liver cells. Therefore, we believe that combining transactivation and binding activity as well as affinity evaluation, the system could be used to screen non-agonist PPARγ ligand as anovel PPARγ modulator

The SRY gene from buffalo (Bubalus bubalis) genome was amplified by the polymerase chain reaction ( PCR) with primers based on the sequence of Hostein SRY gene. The amplified fragment was 2005 bp include 5UTR ( 1 - 504bp) and 3'UTR(1196 - 2005bp). And the amplified fragment was cloned and sequenced. Sequence analysis showed that the coding region of SRY gene (505 - 1195bp) from buffalo was highly homologous with those of other bovine counterpart genes (96% homology) , especially in the HMG box region (99%homology). It was found that there were only signal on male buffalo genome on Southern blot,which indicate SRY gene are highly conservative on evolves.

Abstract: Total RNA was isolated from Siraitia grosvenorii fruit by the method of modified Trizol, according to S. grosvenorii fruit characteristics of rich phenols, polysaccharide, oil and proteins. The OD260/280, OD260/230, RNA integrity (RIN) and yield of the total RNA with this method were 2.01, 2.02, 9.50 and 260 mirog.g-1, respectively. The open reading frame (ORF) of dehydroascorbate reductase (DHAR), named as SgDHAR, was cloned by rapid amplification of cDNA ends (RACE) and RT-PCR method from S. grosvenorii. The GenBank accession number for this gene is KC907731. The SgDHAR gene contains a full-length cDNA of 1,252 bp including ORF of 819 bp and encodes a predicted protein of 272 amino acids. The molecular mass is 30.217 7 kD and the isoelectric point is 8.76. Homology comparison showed that it shared 87% nucleotide sequence homology with Cucumis sativus. Expression patterns using qRT-PCR analysis showed that SgDHAR was mainly expressed in fruit and stem, followed by flower, and was lowest in root, while the expression level was 6.83 times in triploid. T than that in diploid. Therefore, SgDHAR gene may be involved in abortion of triploid seedless S. grosvenorii.

Objective To investigate the clinical features,diagnosis and therapy of adrenal incidentalomas. Methods The data of 66 cases of adrenal incidentalomas were retrospectively analyzed. Results The accuracy rates of localization detected by B-Ultrasound,CT scan and MRI were 84.3%,100% and 100% respectively. The accuracy rates of qualitative diagnosis by B-Ultrasound, CT scan and MRI were 30.0%,75.5% and 79.2% respectively. There were 60 cases underwent operation and the postoperative pathological examination confirmed that there were 31 cases of adrenal cortical adenoma, 6 cases adrenal cyst, 5 myelolipoma, 5 pheochromocytoma, 3 adrenal cortical carcinoma, 3 metastatic carcinoma, 3 ganglioneuroma, 1 adrenal neurilemmoma, 1 adrenal hematoma, and 1 nodular hyperplasia of adrenal cortex. Conclusions Ultrasonography is the first choice of scanning adrenal incidentaloma. However the CT scan and MRI are satisfactory in localization of the tumour. The qualitative diagnosis of adrenal incidentaloma will depend on the diameter, imaging features of tumors, the age of patients, and endocrine examination.
