Objectives To evaluate the therapeutic effect of argon laser photocoagulation combined with intravitreous injection of triamcinolone acetonide (TA) on ischemic central retinal vein occlusion (CRVO). Methods Argon laser photocoagulation combined with intravitreous injection of TA was performed on 17 patients (17 eyes) with CRVO between December 2003 and July 2004. Results During the follow-up of 4-10 months, the visual acuity improved in 16 patients, including alleviated or even disappeared cystoid macular edema (CME) in 5, and recurred macular edema in 5 with decreased visual acuity after 3 months. Six patients had increased ocular pressure after intra-ocular injection which alleviated after treated suitably. No neovascularization in angle or secondary neovascular glaucoma was found. Conclusion [WTBZ]Argon laser photocoagulation combined with intravitreous injection of TA may improve the visual acuity and reduce complications in ischemic CRVO, though macular edema may recur in some cases.

Objective To analyze the feasibility, safety, and technique of laparoscopic myomectomy in patients with large hysteromyoma. Methods A total of 82 hysteromyoma patients with the uterus larger than 14-week gestational size were treated by laparoscopic myomectomy. The outcome of the operation were compared with that in 182 hysteromyoma cases with the uterus smaller than 14-week gestational size. Results In the 82 patients with the uterus larger than 14-week gestational size, 77 were treated successfully by laparoscopy, in which pneumoperitoneum was used in 68 cases and gasless laparoscopy in the other 9. One of the cases converted to open surgery, and small abdominal incision was made in 4 patients. Compared with the patients with the uterus smaller than 14-week gestational size, the 77 patients who had been successfully by laparoscopy had longer operation time [(157.6?89.7) min vs (35.3?26.2) min, t=16.926, P=0.000] and more blood loss [(218.0?108.2)ml vs (108.5?67.5)ml,t=9.904,P=0.000]. Conclusions Myomectomy can be performed under a laparoscope for patients with the uterus larger than 14-week gestational size. Highly skilled technique is important for the surgery.!Gasless laparoscopy is applicable to myomectomy for patients with the uterus smaller than 16-week gestational size.

Objective To investigate the inhibitory effects and related mechanism of S100A4 gene silencing on oxygen-induced retinal neovascularization.Methods 7-day-old C57BL/6J mice were randomly divided into 5 groups including normal group,normal-S100A4 group,oxygen induced retinopathy (OIR) group,OIR-S100A4 group,OIR-green fluorescent protein (GFP) group.To establish the OIR model,mice from all groups except normal one were exposed to (75±2) ％ oxygen for 5 days and then to room air.In the OIR-S100A4 group and OIR-GFP group,the OIR mice were given an intravitreal injection of 1 μl of 1.0 × 109 PFU/ml adenovirus of Ad-S100A4-RNAi or Ad-GFP at P12,and then returned to normoxia for the next 5 days.In the OIR group,OIR was induced in C57bl/6J mice from P7 to P17.In the normal-S100A4 group,the normal P12 mice were give an intravitreal injection of 1 μl of Ad-S100A4-RNAi adenovirus,and maintained in room air from P12 to P17.In normal group,newborn mouse litters were maintained in room air from P0 to P17 without any treatment.Mice in all five groups were euthanized at P17,and retinas were collected for biochemical assays and morphological study.Retinal neovascularization (RNV) was evaluated by counting the number of pre-retinal neovascular cells and the whole mount immunofluorescent staining of the mouse retina.Protein and mRNA expression levels of S100A4,cAMP responsive element binding protein (CREB),B cell lymphoma-2 (bcl-2),Caspase-3 were determined with western blot and real-time PCR.Results The number of pre-retinal neovascular cell nuclei in retinas from OIR-S100A4 group were obviously lower than those in the retinas from OIR group and OIR-GFP group (t=13.61,14.64;P＜0.05).In OIR-S100A4 group,the retinal neovascular tufts area and the vaso-oblitertion area were both significantly smaller than those in OIR group and OIR-GFP group (P＜0.05).Protein level of CREB and bcl-2 were significantly down-regulated in OIR-S100A4 group than those in OIR and OIR-GFP group (P＜0.05).On the contrary,protein levels of Caspase-3 were up-regulated in OIR-S100A4 group than those in OIR and OIR-GFP group (P＜0.05).Conclusion Ad-S100A4-RNAi transfer ameliorates RNV in mouse model of OIR maybe through down-regulating the expression of bcl-2 and CREB,and up-regulating the Caspase-3.

Objective To screen the target genes that contribute to cisplatin resistance in ovarian cancer treatment. Methods Gene expression and methylation profiles of ovarian cancer cells that were sensitive or resistant to cisplatin with accession number GSE15709 were downloaded from GEO database. Differential expressed and methylated genes were identi?fied through associating packages in R. DAVID database to screen the enriched GO terms and pathways of the different ex?pressed genes between A2780 and A2780/DDP. Gene Set Enrichment Analysis (GSEA) of different gene was performed against DAVID database. Genes that exhibited difference in both expression and methylation profiles between the two types of ovarian cancer cells as well as genes that present contradictory profile between expression and methylation were verified via qRT-PCR. Results We found 416 different expressed genes and 281 methylated genes between the two types of ovari?an cancer cells respectively. These differential genes were rich in pathways of cell cycle, DNA replication, nucleus division , p53 signaling , and negative regulation of protein modification process etc. Four genes demonstrated contradictory profile be?tween expression and methylation in the two types of ovarian cancer cells and were verified by qRT-PCR. Conclusion Combination of bioinformatics and molecular biology is useful in the identification of target genes that contribute to resis?tance of cisplatin in ovarian cancer treatment and further reveal molecular mechanism behind it.
