The invasion and metastasis of esophageal carcinoma is associated with several tumor marker on oncogenesi and tumor development,including matrix metalloproteinase,cell adhesion molecules CD44,pituitary-tumour transforming genes.Studies have shown that these tumor markera are over-expression in esophageal carcinoma,which affect the progress and prognosis of esophageal carcinoma,and their specificity and value for clinical application need to be futher studied.

Three components have been isolated from Zebrina pendula Schnizl and identified as ?-sitosterol, 3?, 5?, 6?-trihydroxy stigmast and succinic acid. As a result the anti-tumor rate were 43% (160mg/kg)for succinicacid, 91% (100mg/kg) for ?-sitosterol and 98%(100mg/kg) for 3?, 5?, 6?-trihydroxystigmast, respectively, after anti-cancer test of ascites type-180 sarcoma of mice. It was found that the last hadn't toxicity when its dose was increased.

Objective To explore the mechanism of vitamin E on delaying skin aging by observ-ing the expression of hyaluronic acid synthetase-2 (HAS-2) in human dermal fibroblasts in vitro. Methods Human skin fibroblasts were cultured in vitro, and these fibroblast cells were then divided into 3 groups: different concentration of vitamin E (0, 0.1 × 10-10, 1 ×109mol/L) was added in the medium in the different group. 24 hours later, the fibroblasts were collected, RNAs extracted, and then amplified by RT-PCR. The PCR product was determined by agarose gel electrophoresis, to analyze the level of HAS-2 mRNA expression. Results RT-PCR showed the lever of HAS-2 mRNA was higher in the low-dose group than the control group, with significant difference (P<0.05) ; the lever of HAS-2 mRNA was higher in the high-dose group than control group, with significant difference (P<0.05). There was no significant difference in the lever of HAS-2 mRNA between the low-dose group and the high-dose group. Conclusions Vitamin E can enhance the expression of hyaluronic acid synthetase-2 mRNA, may increase the synthesis of HAS in skin fibroblasts and increase water content in the skin, so that it might reverse or delay the skin aging.

Purpose　To evaluate the therapeutic effect of laser-induced chorioretinal venous anastomosis for retinal vein occlusion　(RVO)．　Methods　The investigation included 28 consecutive patients　(28 eyes) with RVO．The non-ischemic group 18　cases　(18 eyes) were treated with the krypton red laser to induce chorioretinal venous anastomosis， the ischemic group underwent the same therapy and the grid or scatter-type photocoagulation at the same time． All of the eyes were followed up for more than 5 months， and with an average period of 6．6 months．　Results　Seven cases　(7 eyes， 38．9%) of the non-ischemic group created successful chorioretinal venous anastomosis， with mean improvement of 4．43±0．78　standard deviation　（±s） lines of best-corrected visual acuity compared to　0．19±0．67　（±s） lines for 11 eyes with unsuccessful anastomosis　(P<0．001)． None of the seven eyes developed to ischemic state． Four of the 11 eyes with unsuccessful anastomosis converted to ischemic type (36．4%)． Two cases of the ischemic group created successful anastomosis with improvement in visual acuity． The other cases had no change in visual acuity．　Conclusion　Laser-induced chorioretinal venous anastomosis is a new therapeutic method for RVO， especially for nonischemic type　and successful anastomosis can decrease the conversion rate of the vein occlusion to an ischemic state．

MicroRNAs can post-transcriptionally regulate the expression of their target mRNAs. MicroRNA-126 plays an important role in tumorigeness by targeting EGFL7, HOXA9, IRS-1 and p85-β. Intriguingly, it is downregulated in a wide range of tumors and is testified that it functions as a tumor suppressor in lung cancer, leukemia, breast cancer and ovarian cancer.

Attenuated Salmonella can be used not only as live vaccines but also as vectors for exogenous genes. As vectors, attenuated bacteria can deliver genes directly to tumor tissues, leading to the expression of the cloned genes and induction of specific anti-tumor immunologic responses to inhibit tumor growth. Using attenuated Salmonella as a vector offers a new approach for vaccine development.

Objective To summarize the prognosis of elderly patients with colorectal cancer excision who were divided into different groups by the nutritional status before their surgery.Methods In our hospital,100 patients (age from 64 to 70)with colorectal cancer were performed the screening of nutritional risk by NRS2002 before surgery.Patients with score from 1 to 2 were as the group A,and patients with score over 3 were as group B.The related indexes and recovery between two groups were compared.Results The NRS2002 rating scale score showed that 76 patients were at nutritional risk,37 cases among them received nutrition support and had faster recovery of intestinal function the time of tube pulled out after operation[(1.8 ±0.4)d vs.(2.9 ±1.5)d],exhaust time[(2.4 ±0.6)d vs.(4.3 ±0.9)d],time of in-take food[(2.9 ±0.5)d vs.(4.5 ±1.1)d],length of stay[(10.8 ±0.9)d vs.(14.1 ±1.3)d],incidence of infection related complica-tions (0 vs.5.13%),the differences were statistically significant(P <0.05).Conclusion Problems exist in varying degrees of loss of nu-trition in elderly colorectal cancer patients before surgery,an objective assessment of the extent and targeted care and nutritional support can significantly improve the postoperative nutrition and to facilitate recovery of gastrointestinal function after surgery.

Objective To evaluate the application value of serum endotoxin combined with integrated model for end-stage liver disease (iMELD) in evaluating the short and medium term prognosis of patients with decompensated liver cirrhosis.Methods The clinical data of 68 patients with decompensated liver cirrhosis were retrospectively analyzed.The patients were divided into survival group and death group according to the result of follow-up at the 3,6 and 12 months.The iMELD score and Child-Turcotte-Pugh (CTP) score were calculated according to relevant indicators,and the serum endotoxin level was detected.The correlation between serum endotoxin and iMELD score was analyzed in the short and medium term prognosis in patients with decompensated liver cirrhosis.Results After 3 months' follow-up,5 patients died.The iMELD scores in survival group and death group were (39.26 ± 7.29) and (49.29 ± 8.63) scores,CTP scores were (9.32 ± 2.12) and (12.03 ± 2.75) scores,serum endotoxin levels were (9.21 ± 2.24) and (15.39 ± 5.12) ng/L,and there were statistical differences (P ＜ 0.05).After 6 months'follow-up,12 patients died.The iMELD scores in survival group and death group were (41.35 ± 8.03) and (52.18 ± 10.37) scores,CTP scores were (9.78 ± 2.05) and (12.93 ± 1.99) scores,serum endotoxin levels were (8.96 ± 2.41) and (16.43 ±6.03) ng/L,and there were statistical differences (P ＜0.05).After 12 months' follow-up,19 patients died.The iMELD scores in survival group and death group were (40.74 ± 6.38) and (52.29 ± 8.53) scores,CTP scores were (10.01 ± 2.23) and (13.27 ± 1.69) scores,serum endotoxin levels were (8.53 ± 2.34) and (16.52 ± 6.08) ng/L,and there were statistical differences (P ＜ 0.05).The area under curve of receiver operating characteristic (ROC) was 0.952,standard error was 0.048,and 95％ confidence interval was 0.790-1.022.The best critical value of iMELD score to predict death was ≥48.00 scores,and the risk of death would rise if iMELD score was increased.The best critical value of serum endotoxin to predict death was ≥ 11.00 ng/L.Conclusion iMELD score and serum endotoxin have important value in predicting prognosis in patients with decompensated liver cirrhosis.

Objective To translate the English version of the Medication Adherence Self-efficacy Scale (MASES) into Chinese and to test the reliability and validity of the Chinese version of MASES in patients with hypertension.Methods Totally 285 patients with hypertension were recruited and were investigated by the Chinese version of MASES.The results underwent analysis for reliability and validity.Results The retest reliability of MASES was 0.843.The Cronbach α of the Chinese version of MASES was 0.876.The Cronbach α of the four dimensions ranged from 0.794 to 0.905.The average content vality index (CVI) of the scale was 0.946.Factor analysis got four factors,which explained 68.683％ of the total variance.The factor loading of each item on its common factor was ＞0.4.Conclusions The Chinese version of MASES has been proved to be reliable and valid.It can be used as a valid tool for the measurement of the patient compliance in patients with hypertension.
