Objective To study the values of continuous renal replacement therapy (CRRT) for the treatment of multiple organ dysfunction syndrome ( MODS) induced by sepsis. Methods A total of 62 patients with MODS were divided into three groups, namely non-CRRT group, short period CRRT group (24 ~ 48 h) and long period CRRT group( >48 h). Relevant factors including organ function, plasma endothelin-1 (ET-1),sepsis-related organ failure assessment(SOFA)score, average length of survival time and accumulative survival rate were analyzed . Results Compared with non-CRRT group, a statistically significant difference in SOFA score was evident on the 4th day after long period CRRT group and on the 6th day after short period CRRT group. The survival rates of three groups on the third day after treatment were 56. 3% 、 83.3% and 88.9%, respectively (P< 0.05). The survival rates of three groups three weeks after treatment were 53. 1% , 58. 3% and 66.7% , respectively (P>0.05). The average lengths of survival time in three groups were(4.4 ±2.6)days, (9.5 ±6. l)days and (10.3 ±5.4)days, respectively. Compared with non-CRRT group, the average lengths of survival time were longer in the other two groups. The levels of serum ET-1 significantly decreased after CRRT treatment (P<0.05). Conclusions The organ function and survival rate could be improved by CRRT. Average lengths of survival time were significantly prolonged in two CRRT groups(P <0.05). More effective therapeutic results including lower SOFA score and longer average length of survival time were observed when the course of CRRT was extended longer properly.

AIM:To evaluate the clinical effect of traditional Chinese medicine plus laser photocoagulation on eyes which have peripheral retinal hole with shallow detachment.
METHODS: The 227 cases ( 246 eyes ) of retinal hole with shallow detachment were randomly divided into an integrated Chinese and western medicine group and a western medicine group. The former underwent laser photocoagulation combined with oral Chinese medicine;while the latter was treated with laser photocoagulation alone. Analyses of the effect were performed two months after treatment.
RESULTS:The total cure rate of integrated Chinese and western medicine group was 87. 7%, while that of western medicine group was 71. 6%, significant difference was considered between the two groups (P<0. 01).
CONCLUSION: Chinese medicine combined with laser photocoagulation plays an exact role in eyes which have peripheral retinal hole with shallow detachment, especially when the detached range is greater than 1PD, and it is significantly better than western laser therapy.

Objective To investigate the mechanism of Sut melanocytes growth inhibition in response to xCT -deficiency. Methods TTotal proteins were extracted from xCT-deficient Sut melanocytes and wild melanocytes, respectively, and were separated by 2-dimensional electrophoresis. Altered expression profile of proteins of Sut melanocytes was analyzed by PDQuest software and compared with that of wild melanocytes.Proteins with significant change were chosen to be identified by mass spectrometry and database query.Results Twenty proteins in Sut melanocytes altered significantly compared with wild melanocytes. Ten of the proteins were up-regulated, while the other tens were down-regulated. Four proteins from both up-regulated and down-regulated were identified respectively: up-regulated proteins were Tubulin alpha-1b, S100-A6,Nucleoside, S-formylglutathione, and down-regulated proteins were Calumenin,NDRG1 ,DPYSL2, 14kDa unknown protein. Conclusion The identification of the xCT-deficiency related proteins may provide supporting evidence for the mechanism research of Sut melanocytes' growth inhibition caused by xCT-deficiency.
