Objective To investigate the relevant risk factors for fungal infection following operation of the gastrointestinal neo- plasm and offer supporting data for the prevention of fungal infection.Methods Medical records from 116 patients who under- went the operation of gastrointestinal neoplasm in the special group of this hospital from January 2006 to June 2006 were retro- spectively reviewed on the relevant risk factors by univariate and multivariate Logistic regression analysis.Results Of the 116 patients reviewed, 18 had fungal infection.Forty-six samples were positive for fungal pathogen.The most frequently isolated fungal strain was Candida albicans (15/20) and the most common infection site was gastrointestinal tract (14/18).Fungal in- fection after the operation of gastrointestinal neoplasm was significantly relevant with the duration of antibiotic use, duration of post-operative fasting, low serum albumin, high blood glucose and complication of bacterial infection.The duration of antibiotic use was a significantly independent risk factor.Conclusions Reasonable antibiotic use, nutritional support, early enteral nutri- tion and control of blood glucose should be taken into account after the operation of gastrointestinal neoplasm in order to prevent fungal infections.

Objective To explore the expressions of Survivin and VEGF and relationship between them in hepatocellular carcinoma(HCC).Methods The expressions of Survivin protein and VEGF protein in 50 HCC.30 cirrhosis and 10 normal tissues were assessed by immunohistochemical method.The expressions of Survivin mRNA and VEGF mRNA in 50 HCC,30 cirrhosis and 10 normal tissues were assessed by in situ hybridization.Results The expressions of Survivin and VEGF in cancer tissues,cirrhosis tissues,normal tissues weresignificantly different. The expression of Survivin in HCC tissues was stronger than that in cirrhosis,but the expreesion of VEGF in cirrho- sis was stronger than that in HCC tissues.Conclusion The expression of survivin.is closely associated with the ex- pression of VEGF in HCC and they take positive correlation.The abnormal expressions of Survivin and VEGF are closely associated with the development of HCC.They may play important roles in the development of HCC.

AIM: To observe the effect of Ahmed glaucoma valve implantation intravitreal bevacizumab in the treatment of neovascular glaucoma ( NVG) .
METHODS:Twenty-two cases (22 eyes) who presented with NVG were first treated with intravitreal bevacizumab 0. 1mL ( 2. 5mg ), then with Ahmed glaucoma valve implantation after regression of iris neovessels. Cases were followed - up for 6 - 36 ( mean 24 ) mo with observation on visual acuity, IOP control, regression of iris neovessels, and complications during or after surgery.
RESULTS: Iris neovessels was regressed in different degree after injection within 1wk in 22 eyes. At final follow-up, the IOP of 18 eyes were all less than 21mmHg without any drugs and of 3 eyes with 1-3 kinds of anti-glaucoma drugs after combined Ahmed glaucoma valve implantation. The IOP of one eye was controlled after cryotherapy. The mean IOP dropped from 45. 36 ±8.13mmHg preoperatively to 15. 59 ± 3. 21mmHg postoperatively. IOP reduction was statistically significance between preoperative and postoperative ( P<0. 05) at final follow-up. Visual acuity was improved in 9 eyes (41%) and was no changed in 13 eyes. No serious complications were observed during or after intravitreous bevacizumab injection and Ahmed glaucoma valve implantation.
CONCLUSION: Ahmed glaucoma valve implantation and intravitreal bevacizumab in the treatment of NVG is useful and safe. It improves the success rate of surgery and preserves visual function, furthermore its complications are less.

Objective To observe the protection of human keratinocyte cell line, HaCaT cell, from UVA damage by resveratrol and its possible mechanism. Methods HaCaT cells were incubated with or without 0.01 mmol/L or 0.1 mmol/L resveratrol after exposure to 5 J/cm2 UVA irradiation. Unirradiated HaCaT cells-without the treatment with resveratrol served as the control. After another 24-hour culture, MTT assay was used to detect the proliferation of cells, RT-PCR and Western-blot to measure the iNOS mRNA and protein expression respectively, electron microscopic technique to observe the changes in cell ultrastructure. Results After irradiation with UVA of 5 J/cm2, the proliferation of HaCaT cells decreased with the absorbance at 490 nm descending from 0.889±0.083 to 0.542±0.004, while a significant increase was observed in the relative expression level of iNOS mRNA and protein in HaCaT cells (1.532±0.041 vs 0.009±0.003, 1.331 ±0.046 vs 0.003±0.001, both P < 0.05) with the presence of typical apoptotic cells. The treatment with 0.01 and 0.1 mmol/L resveratrol significantly promoted the proliferation of irradiated cells with the absorbance at 490 nm being 0.753±0.435 and 0.892±0.173 respectively, but inhibited the mRNA (0.853±0.038 vs 1.532±0.041, 0.392±0.033 vs 1.532±0.041, both P< 0.05) and protein expression level (0.809±0.018 vs 1.331±0.046, 0.412±0.026 vs 1.331±0.046, both P< 0.05) of iNOS in irradiated cells, and the resveratrol of 0.1 mmol/L was more effective than that ofO.01 mmol/L in all tested parameters (P< 0.05). Furthermore, no apoptofic cells or necrotic cells were observed in irradiated ceils incubated with resveratrol. Conclusion Resveratrol effectively protects HaCaT cells from UVA damage, which may be related to the inhibition of UVA-induced iNOS expression by resveratrol.
