BACKGROUND:Research on liver transplantation has not just focused on survival rate and survival time, and the quality of life has become a new field of study. However, it is stil a blank about the quality of life of liver transplant recipients in Xinjiang. OBJECTIVE:To investigate the quality of life of liver transplant recipients in Xinjiang and to explore the main risk factors for the quality of life in patients. METHODS: A Chinese version of the SF-36 health survey was used to retrospectively evaluate the quality of life of liver transplant recipients in Xinjiang. RESULTS AND CONCLUSION:The scores of al eight dimensions in the patients with liver transplantation ranged from 60.6±18.7 to 93.9±22.1. Primary diseases, operation method, marital status, level of education, occupation, gender and age could influence the quality of life of the liver transplant recipients, but nation, income and the way of medical insurance had no significant effect on the quality of life. These findings indicate that there is no obvious difference in the quality of life between liver transplant recipients and normal population, and the scores in six dimensions are higher in the liver transplant recipients than normal population, which is further confirmed that liver transplantation is an effective way for treatment of advanced liver disease.

Objective To observe the clinical effect of anterior capsule relaxing incisions with Nd:YAG laser in treating postop-erative anterior capsule contraction in high-risk cataract patients.Methods 120 high-risk cataract patients with postoperative ante-rior capsule contraction collected from December 2010 to November 2012 were divided into experimental group(performed the ante-rior capsule relaxing incisions on postoperative 3 d)and control group.The anterior capsule opening area was measured immediately after laser operation(baseline),in postoperative 1,3,6 months by using the Scheimpflug video photogeaphy system,and the descent rate of the opening area was simultaneously calculated.The decentration degree and tilt of intraocular lens(IOL),posterior capsule opacification and other complications were also assessed.Results Of the observed 120 cases,40 cases were pseudo posterior capsule stripping syndrome,40 cases were primary angle closure and 40 cases were diabetic retinopathy.There was no statistically signifi-cant difference in the baseline value of the opening area between the experimental group and the control group(P>0.05).In the ca-ses of primary angle closure 1,3,6 months after operation,the anterior capsule opening area in the experimental group was signifi-cantly increased compared with the control group(P<0.05)and the descent rate of the opening area was significantly diminished (P<0.05).In the cases of pseudo posterior capsule stripping syndrome or diabetic retinopathy,although there was no statistically significant difference in anterior capsule opening area between the experimental group and the control group(P>0.05),the descent rate of the opening area was significantly diminished(P<0.05).No significant differences were found in the aspects of IOL decen-tration and tilt,posterior capsule opacity,or other complications.Conclusion YAG laser anterior capsule relaxing incisions in the early period after cataract surgery is safe and effective in preventing anterior capsule contraction in high-risk patients.

Objective To explore the roles of Notch2,Notch4 in hyperoxia induced lung injury in premature rats.Methods At the postnatal 1 day Sprague-Dawley premature rats were randomly assigned to about 85% hyperoxia group and air group.At the 1,7,14,21 days after exposed,8 rats of each group were used to evaluate expressions of Notch2,Notch4 in lungs by immunohistochemistry and the level of Nothch2,Notch4 mRNA by reverse transcription polymerase chain reaction(RT-PCR).Results Expressions of Notch2,Notch4 had their rules in rats′ different stages of development;85% oxygen exposed would change their tracks.Conclusion Prolonged 85% oxygen exposure result in abnormal expressions of Notch2 and Notch4 ,which is likely to lead to the pathogenesis of hyperoxic lung injure in premature rats.

Objective To improve the understanding of malignant triton tumor on imaging findings.Methods CT and MRI findings of rare malignant triton tumor in 3 cases confirmed histologically were analysed with review of the literatures.Results 3 tumors included prostatic malignant triton tumor with pulmonary metastatic tumors and neurofibromatosis-I in 1 case,left haunch malignant triton tumor in 1 case and right maxillary sinus malignant triton tumor with destruction of maxillary sinus paries in 1 case.The imaging appearances of tumors were the huge soft tissue mass which strongly suggested malignant tumors,high signal intensity on T2WI,circular septa inside the tumors with low signal intensity.Conclusion Although the qualitative diagnosis of malignant triton tumor depends on pathological examination,CT and MRI play a useful role in diagnosis and differential diagnosis of this tumors.

Objective To investigate the expression of miR-195 and its association with clinicopathologic features in gastric cancer. Methods The expression level of miR-195 in 30 cases of gastric cancer and matched non-tumor adjacent tissue specimens were examined by using reverse transcription real-time PCR.The relationship between the expression of miR-195 and its clinicopathologic features of gastric cancer was analyzed.At the same time, the expression of miR-195 in four gastric cancer cell lines and normal human gastric epithelial cells were detected. Results The expression level of miR-195 was significantly lower in the tumor tissues than that in the adjacent tissues (P<0.05). Down-regulated miR-195 expression was associated with lymph node metastasis (P<0.05) in gastric cancer patients. Clinical and pathological analysis showed that miR-195 in gastric carcinoma tissues had no relationship with sex, age, the degree of tumor differentiation and tumor metastasis stage. Conclusion It is possible that miR-195 plays an important role in the generation and progression of gastric cancer, and it was associated with lymph node metastasis in gastric cancer patients.
