A total of 60 myopia patients (120 eyes) who were going to undergo myopia LASIK were selected in this study. The patients were divided into two groups of anisometropia and non-anisometropia,each group had 30 patients (60 eyes). Checked vision, fusion range,near and distant stereoscopic at 10 day pre-operation and at 1,3 and 6 month in post operation. After the LASIK, all of 60 patients' anisometropia were significantly reduced, binocular stereopsis were obviously improved than pre-operation, especially the anisometropia group; the binocular fusion range also got better,but there was no significant difference between the two groups. This study clarified that the visual function of anisometropia could be improved after LASIK.

Objective To investigate the quality of life and its influencing factors in hver transplantation recipients in order to supply scientific reference for improving their life quality.Methods 33 patients with terminal liver diseases waiting for liver transplantation(the pre-operation group)and 102 patients 2 weeks after liver transplantation and outpatients for follow-up visits(the post-operation group)were conducted with SF-36,self-rating anxiety scale,self-rating depression scale,and social support questionnaire.Results Except for the scores of physiological function,emotional role,social function in SF-36.differences of scores of other factors were evident between the preand post-operation groups.Life quality of patients over 1 year after operation was better than those within 1 year. The influencing factors of QOL were subjective support and anxiety.Conclusions After liver transplantation,the patients' QOL evidently improves.Life quality of patients over 1 year after operation was better than those within 1 year.Patients' QOL is positively related to subjective support,negatively related to anxiety.

Objective To explore the influence of Roy adaptation mode and resistance training on cardiac function and life quality of patients with chronic heart failure. Methods One hundred patients with chronic heart failure in our hospital cardiovascular department were enrolled in the study. All patients received conventional treatment of chronic heart failure. They were equally divided into the control group and the observation group using random digit grouping method. The control group received conventional nursing mode and observation group received Roy adaptation mode joint resistance training. The cardiac function and life quality of two groups were compared after two months. Result After three months′intervention, each index of cardiac function was significantly better than that of the control group ( P < 0 . 01 ) , 6 minutes waking distance of the observation group was significantly longer than that of the control group ( P < 0 . 01 ) , and the life quality score was significantly higher than that of the control group (P<0.01). Conclusion The Roy adaption mode and resistance training can improve heart function and the overall quality of life of the patients with chronic heart failure.

Purpose To study the clinicopathologic features, differential diagnosis, immunophenotype and treatment and prognosis of adult intratesticular rhabdomyosarcoma ( ITRMS) . Methods One case of adult ITRMS was analyzed by histology and immunohisto-chemistry, the date of treatment and prognosis through electronic medical record. The published relevant literatures were reviewed. Re-sults A 19-years old male patient was admitted to the hospital with a history of 2-months testicular painless enlargement. Testis ultra-sound examination and scrotal and abdominal CT revealed a mass in right testis. Macroscopic observation of the testis showed that a grey-white tumor. The tunica albuginea, epididymis and spermatic cord hadn’ t been invaded by the tumor. Microscopically, medium-size oval or round cells were arranged in sheets, and spindle-shaped, strap-like, large-circle cells were also presented. Few large cells had abundant granular eosinophilic cytoplasm with crossstriations under oil immersion objective. Immunohistochemically, the tumor cells were positive for vimentin, HHF35, desmin, MyoD1, Myogenin and h-Caldesmon protein, more than 50% neoplasm cells were positive. The rate of Ki-67 was 75%. Conclusions Adult ITRMS is rare. Histologically, embryonal rhabdomyosarcoma ( ERMS) is the most common type. They have highly invasive and poor prognosis. The accurate diagnosis depends on the combination of the histo-logic and immunohistochemical examination.

Artemisnin is a novel sesquiterpene lactone with an internal peroxide bridge structure, which is extracted from traditional Chinese herb Artemisia annua L. (Qinghao). Recommended by World Health Organization, artemisinin is the first-line drug in the treatment of encephalic and chloroquine-resistant malaria. In the present study, transgenic A. annua plants were developed by overexpressing the key enzymes involved in the biosynthetic pathway of artemisinin. Based on Agrobacterium-mediated transformation methods, transgenic plants of A. annua with overexpression of both HDR and ADS were obtained through hygromycin screening. The genomic PCR analysis confirmed six transgenic lines in which both HDR and ADS were integrated into genome. The gene expression analysis given by real-time quantitative PCR showed that all the transgenic lines had higher expression levels of HDR and ADS than the non-transgenic control (except ah3 in which the expression level of ADS showed no significant difference compared with control); and the HPLC analysis of artemisinin demonstrated that transgenic A. annua plants produced artemisinin at significantly higher level than non-transgenic plants. Especially, the highest content of artemisinin was found in transgenic line ah70, in which the artemisinin content was 3.48 times compared with that in non-transgenic lines. In summary, overexpression of HDR and ADS facilitated artemisinin biosynthesis and this method could be applied to develop transgenic plants of A. annua with higher yield of artemisinin.
