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.

Gastric-oesophageal varices were found in 3 cases of cirrhosis, compression and displacment of hepatic artery and portal vein were shown in one case of polycystic liver.Conclusion 3D DCE MRA is an efficiency, noninvasive technique, it offers great help in evaluating pre-operative vasculature of liver transplantation.

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

Objective To establish a method for the isolation of Zika virus and to gather experi-ences for viral isolation. Methods Suckling mice at age 1-3 days were inoculated with serum samples posi-tive for Zika virus through intracranial injection. All mice were sacrificed 6 days after the injection. Viral nu-cleic acids were extracted from brain, heart, liver, spleen, lung, kidney, muscle, skin and intestine tissue samples and analyzed by real-time RT-PCR. The supernatants of brain tissues positive for Zika virus were used for subculturing. Nested PCR was performed to amplify the NS5 gene of the isolated virus. The se-quences of NS5 gene were analyzed by using MEGA6. 0 software. Results All of the tissue samples were positive for Zika virus. Higher viral loads were detected in heart and brain tissue samples with cycle thresh-old (Ct) values of 24. 4 and 25. 3, respectively. The second generation of Zika virus was identified in suck-ling mice brain tissues 2 days after infection by using real-time RT-PCR. The amplified product of nested PCR was 972 bp in length. Sequencing analysis showed that the isolated Zika virus ( GDZ16002 strain) be-longed to the Asian lineage. Conclusion A strain of Zika virus was successfully isolated in China by using intracranial injection via a suckling mouse model. The isolated Zika virus belonged to the Asian lineage.

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.

This study was aimed to reveal the effects and molecular regulation mechanism of methyl jasmonate (Me-JA) on volatile terpenoids from Amomum villosum Lour. After the leaves and fruits of A momum villosum Lour. were treated with different concentrations of MeJA, the volatile terpenoids of fresh fruits from A . villosum Lour. were ex-tracted with microwave method and analyzed by GC-MS. Then, leaves and fruits treated with MeJA were sequenced by Illumina. The transcriptome data was analyzed by bioinformatic methods. The results showed that there were 20 and 33 volatile terpenoids detected in peels and seed groups, respectively. Contents of volatile terpenoids in peels and seed groups were both improved after 600 μmol·L-1 MeJA treating fruits for 24 h, such as bornyl acetate, cam-phor, borneol, and etc. While 200 μmol·L-1 MeJA treating different parts for 24 h can regulate the biosynthesis of some volatile terpenoids in peels differently. And 200 μmol·L-1 MeJA treating fruits can improve the content of ma-jor volatile terpenoids in seed groups. A total of 68 168 unigenes were obtained with de novo assembly, and 48 627 unigenes were annotated after comparison with public protein databases. Analysis of functional annotation against KEGG database showed that there were 208 unigenes closely related with metabolism of volatile terpenoids and 22 u-nigenes related with MYC2 transcription factors. It was concluded that MeJA can effectively regulate the metabolism of volatile terpenoids from A . villosum Lour. There were a lot of candidate genes related with the biosynthesis of volatile terpenoids obtained by analyzing the transcriptome data which also provided a large amount of data for the discovery and regulation of functional genes related with the biosynthesis of volatile terpenoids from A . villosum Lour.
