Objective To summarize the modern treatment of rectal cancer(RC). Methods A literature review was made on the modern therapy of RC. Results Pre-and post-operative chemotherapy and radiotherapy, mesorectal resection, and low RC resection and anastomosis using anastomat to preserve the anus could improve the resection rate, 5-year survival rate and life quality in patients with RC, as wall as could reduce recurrence rate of RC after resection. Conclusions Pre-and post-operative chemothapy and radiotherapy, mesorectal resection, anastomat application are the ideal treatment for rectal cancer nowadays.

Bioinformatics is a new field of biomedical science which based on biological,information technology to storage,retrieval and analysis the biological data.This emerging subject is important for the improvements of scientific ideas and ability of biomedical graduate students.Based on the medical background and future study of the graduate students,it is a key point that how to performing the teaching work in accordance with the student's aptitude.To promote the level of bioinformatics course and enrich the theory knowledge and ability of practice of the medical graduate students,we discuss three relate issues such as the content of courses,teaching term and teaching model in this paper.

Let-7 is found to be downregulated in lung cancer while many kinds of oncogenes expression always increase, and restoration of the let-7 to normal expression level inhibits lung cancer growth evidently.Thus, let-7 might serves as good targets or effective interference tools in exploration of anticancer therapeutics,and has a good prospect in applying it in the early diagnosis, prognosis and therapy in lung cancer.

Objective To investigate the characteristics and patterns of lymph node metastasis in lung cancer and to provide evidence for determining the range of lymph node dissection.Methods One hundred and eighteen patients with lung cancer received complete resection combined with systematic lymph node dissection according to the mapping system developed by Naruke.Results A total of 835 lymph nodes were dissected from 118 lung cancer patients.The positive ratios of N1 and N2 were 15.6% and 17.4% respectively.Fifteen patients were found with skipping N2 which were located in 2,4,5,6 and 7 lymph node groups respectively.There was no significant relationship between the size of primary tumor and lymph node metastasis.Small cell lung cancer showed the highest risk of lymph node metastasis.The metastatic rate of lymph node in adenocarcinoma was markedly higher than that of squamous cell carcinoma.Skipping mediastinal lymphatic metastasis was found more frequently in lower lobar tumors than that in upper lobar ones.Conclusion Lymph node metastasis of lung cancer may occur in multiple groups and regions,even in a skipping pattern.Systematic lymph node dissection may be routinely performed in pulmonary resection for lung cancer.

Objective: To evaluate the effect of open-chest surgery for cancer patients in advanced stage, in aged and with respiratory insufficiency. Methods: From May 1992 to December 2002, 637 patients with lung cancer underwent thoracotomy in out hospital. 118 of the 637 patients fit in with the standards of advanced, aged or respiratory insufficiency. RVEF was consecutively assessed in 118 before pulmonary resection by echocardiography. According to right ventricular function, the 118 patients were dicided into group A(n=77, RVEF

Objective To explore the correlation between psychosomatic health and depressive symptoms among university students. Methods Using a stratified random sampling method we selected 1197 students from a university in Wuhan and adopted the 21 - item Beck Depression Inventory (BDI) together with a self - designed questionnaire for assessment and data collection. We received completed questionnaires from 1179 students (432 male and 747 female students). We computed the contingency frequency of study variables and examined risk factors for depressive symptom using conditional logistic regression. Results We observed about 30.27% of the young students with depressive symptoms, and 24.34% , 5.0% and 0.93% of them had a mild, modest and severe depressive symptom, respectively. The rate in female students was slightly higher than that in male students (31.86% vs 27.55%). We compared variables such as sex, study year, speciality and liveplace of family with the BDI scores by Chi - square Test, but there was not significant difference. We performed a part of multivariate logistic regressions and adjusted with sex, study year, liveplace of family and singlechild. We found that significant associated risk factors with depressive symptoms included parent(s) with diagnosed psychiatric illness(OR =2.38, P

Objective To investigate the clinical significance of gamete intrafallopian transfer (GIFT) under laparoscope. Methods The gonadotropin was adopted to induce superovulation and the spermatic fluid was managed with the swim-up method. After oviums were dislodged by puncture under laparoscope, gametes were transplanted by intubating the fallopian tube. Results Among a total of 19 patients, 4 were pregnant, the pregnancy rate being 21.1% (4/19). Three women had a delivery at term and 1 had an abortion. No serious complications were seen. Of the 15 unfertilized patients, normal pregnancy was observed within 6 months after surgery in 5 patients, the circle pregnancy rate being 5.6% (5/89). Conclusions GIFT under laparoscope is a practical assisted reproductive technique (ART) that may achieve a relatively high pregnancy rate. Some other pelvic diseases resulting in infertility can be treated simultaneously, which contributes to natural fertilization in the future.

Objective To evaluate efficacy and safety of escitalopram in treating depression. Methods In this randomized, double-blind, double-mimicry, paroxetine parallel controlled study,the study group was treated with escitalopram and the control group with paroxetine. Hamilton Rating Scale for Depression was taken to evaluate efficacy score. Results At the end of six weeks,compared with the total scores of HAMD before and after treatment, escitalopram (17.5±7.8) and paroxetine (16.0±7.9) group both showed the significant difference, while the difference compared between two groups ,the efficacy (87.0% and 81.7%) for depression and side effects were no significance. Conclusion Escitalopram is an efficient and safety antidepressant.

Objective To study the effects of fat grafting on partial jaw deformity.Methods A total of 19 cases of partial jaw deformity.were used fat grafting in past 2.5 years,from January 2012 to June 2015.All analyses were to find suitable fat grafting method for partial jaw deformiw.Fat graft was obtained by low pressure suction and low speed centrifugation.Results A lot of 15 patients in this group had been followed up for 6 months to 2 years.9 patients was satisfied with once fat grafting and 6 with twice.Conclusions Fat grafting provides a useful alternative to partial jaw deformity with normal occlusion.But it also remains to be seen what the forward effects of fat grafting on partial jaw deformity are.

Objective: To summarize the experience of valve replacement for multiple valve insufficiency in patients with giant left ventricle and the operative indication. Methods: Multiple valvular operations were performed in 62 patients with giant left ventricle between 1991 and 2002. Combined mitral and aortic valve replacement was performed in 56, tricuspid valve annuloplasty in 43, left atrium placation surgery in 12, and mitral valve replacement in 5. Results: The early postoperative complication and mortality rate were 45.2% and 17.7%, respectively .The late mortality rate was 6.5%. The main factors influencing the early surgical results were preoperative severe left ventricular enlargement (ESD ≥6.0cmand EDD ≥8.0cm) and systolic dysfunction (EF ≤0 40 and FS ≤0 25), perioperative ventricular fibrillation, postoperative low cardiac output and multiple organal failure. The main factors affecting long term survival were postoperative severe ventricular arrhythmia and left ventricular enlargement with depressed systolic performance. Conclusion: The keys to improve the early and late results of multiple valve replacement in these patients with giant left ventricle are the choice of optimum surgical timing, the proper management of the high risk factors mentioned above during perioperative and follow up periods.
