Prostate cancer is one of the common malignant tumors of the urinary system and mostly found in elderly men. Like most tumors, prostate cancer involves a variety of molecules in its occurrence and progression. More studies on the development of prostate cancer focus on the tumor markers, DNA damage repair related genes, and tumor invasion and metastasis related factors. This article presents an overview on the research progress in these three aspects.

Objective To elucidate the effects of different modes of partial parenteral nutrition (PPN)on immunological function of T-lymphocyte in non small cell lung cancer(NSCLC)patients during chemotherapy.Methods Ninety-three patients with non-small cell lung cancer were randomly divided into three groups:the control group(30 patients),the low dose of PPN(32 patients) and the high dose of NNP(31 patients).Exactly the same chemotherapy was applied to each of three groups.During chemotherapy,three groups were supplied the same diet,the control group received conventional treatment;the low dose group and the high dose group received additional parenteral nutritional support besides diet.The low dose group was given 250 ml 9-AA daily and the high dose group was given 500 ml 9-AA daily.The T lymphocyte subsets CD3~+,CD3~++CD4~+ ,CD3~++CD8~+ and cells were detected respectively before and after chemotherapy.Results In all of the three groups,the percentage of NK cells,CD3~+ and CD3~++CD4~+ cells were decreased significantly before and after chemotherapy(all P＜0.05),In the control and low dose groups,NK cells changed more significantly after chemotherapy(P＜0.01).The percentages of CD3~+,CD3~++CD4~+,CD3~++ CD4~+/CD3~++CD8~+ of the low dose group and high dose group were higher than those of the control group before and after chemotherapy(all P＜0.05),the percentage of CD3~++CD8~+,CD3~++CD4~+/ CD3~++CD8~+ of the low dose group and hight dose group did not change notably(all P＞0.05). Conclusions The chemotherapy on patients with NSCLC will possibly cause malnutrition and immunosuppression.The benefits of giving 9-AA to NSCLC patients who were applying PPN and undergoing chemotherapy may include antagonizing immunological function aggravation,improving nutrition status and improving immunological functions of the T lymphocytes during chemotherapy.

One hundred and five patients with non-ST segment elevation acute coronary syndrome were followed up for 1 year.They were assigned to the event group or non-event group according to the presence of endpoint events(cardiac death and nonfatM myocardial infarction).B-type natriuretic peptide level was measured at 30 days and 1 year and compared between the two groups.The results showed that the level of B-type natriuretic peptide was higher in the event group[(235±107)μg/L vs(154±49)μg/L at 30 days;(259±100)μg/L vs(143±57)μg/L at 1 year].Thus,B-type natriuretic peptide is an important prognostic factor for patients with non-ST segment elevation acute coronary syndrome.

BACKGROUND: Previous studies demonstrated that smooth muscle injury or ischemia/reperfusion injury result in tissue factor (TF) increasing. However, few reports concern the expression and mechanism of TF in venous bypass grafting.OBJECTIVE: To examine changes in TF protein expression in response to venous bypass grafting.DESIGN, TIME AND SETTING: The animal observation experiment was performed at the Department of Cardiovascular Surgery, Affiliated Union Hospital of Tongji Medical College, Huazhong University of Science and Technology from May 2006 to May 2008.MATERIALS: A total of 30 Sprague-Dawley (SD) rats.METHODS: Rats were underwent interposition bypass grafting of the common carotid artery via the ipsilateral external jugular vein. Namely, the proximal end of external jugular vein was ligated at the joints of external jugular vein and internal jugular vein, and the distal end of external jugular vein was ligated before branches. The proximal and distal ends of common carotid artery were occluded by artery clamp, and a 5 mm artery was removed. The proximal end of artery was anastomosed with distal end of artery, and the frontal wall was sutured with posterior wall. After that, the proximal end of external jugular vein was cut down and coincided with the distal end of common carotid artery.MAIN OUTCOME MEASURES: The expression of TF and proliferating cell nuclear antigen (PCNA) was detected by immunohistochemistry. Meantime, TF activity in vessel protein extracts was determined with TF activity assay kit, and the thickness of intima, media were calculated by computer imaging analysis system. The contralateral external jugular veins were served as the control.RESULTS: The adventitia of all vessels showed abundant TF staining. In early vein grafts, TF staining was markedly increased in the intima and media. However, intimal and media TF staining was absent in the contralateral control jugular veins and late vein grafts. The number of PCNA positive cells was increased in the vein grafts at day 3 after grafting, obvious increased at day 7, and reached the peak at day 14. TF activity in whole-vessel protein extracts was similar in control veins and early and late vein grafts. The thickness of neointima of the vein graft increased significantly at days 7, 14, and 28, and the thickness of media increased significantly at days 14 and 28.CONCLUSION: The changes of TF expression at various time points may relate to hyperplasia of neointima.

Objective:To investigate the effects of survivin antisense oligonucleotide (ASODN) on expression of survivin and ACC-M cell apoptosis. Methods: A phosphorothioate antisense oligonucleotide (ASODN) of specific target survivin was designed and synthesized and then transferred to ACC-M cell line by lipofectin. At the same time blank control group, sense oligonucleotide (SODN) group were set up for comparison. MTT assay was used to detect cytotoxicity. Apoptosis was observed by flow cytometry. Survivin expression was determined by RT-PCR and Western-Blotting. Results: Compared with control group and SOND group, in ASODN groups, the expression of survivin mRNA and protein were obviously weak, apoptosis rate apparently increased, cells growth was inhibited. There was no obviously difference in SODN and control groups.Conclusion:ASODN can down-regulate the expression of survivin gene in ACC-M cell line specifically. It plays an important role in inducing tumor apoptosis and suppressing cell proliferation.

Objective To investigate prophylaxis and therapy of early complications following relatives' partial live small bowel transplantation.Methods Four relatives' partial live small bowel transplantations were carried out.Among the 4 patients,there were 3 cases of short intestine syn- drome and one case of non-function of small bowel caused by the absence of nerve ganglion of small in- testine.More than 4 antigens of HLA were completely matched between donators and receptors.In- testines of donators were got from terminal ileum with the length of (150?10) cm.After operations, tacrolimus (FK506),mycophenolate mofetil (MMF),and methylprednisolone were used to prevent rejections.Measures such as use of anticoagulation,improving microcirculation and albumin infusion, aimed at regulating the function of blood coagulation and preventing bleeding and formation of thrombus at anastomotic stoma;famotidine and omeprazole were used to prevent irritable ulcer;use of the third generation of cephalosporins antibiotics,ganciclovir and fluconazol could prevent bacteria,vi- rus and eumycete infections;disinfection and care of easily-infected organs were emphasized;receptors were encouraged to get out of their beds to move frequently;glutamine and enteral nutrition were used early to promote recovery of intestinal function.Results Three days after operation,one patient's lung was infected with baumanii,and the infection had been under control after being treated with the third generation cephalosporins antibiotics;five days after operation,haematoma was detected on an- other patient and was cleared through the second operations growth of eumycete was found in 2 pa- tients' excretion and secretion from enteron,and their situations were improved with fluconazol;acute rejections of the 4 patients were detected 20 days after operation and reversed by the increased use of FK506 combined with methylprednisolone.Among the 4 patients,2 of them have survived for a long time,and the first patient has survived for 6 years and 8 months till now and the other one for 3 years and 2 months;furthermore,other 2 patients respectively died of infections 5 months and 35 days after the operations.Conclusion Because of special constitution of intestine,early complications of rela- tives' partial live small intestine transplantation are frequent and complicated.Therefore,prophylaxis and therapy of early complications are crucial to the success of the transplantation.

This study is to investigate the sedative and hypnotic effects of a novel compound H1208. The sedative activity of H1208 was investigated by recording the spontaneous locomotor activity of mice. The hypnotic property was evaluated by the latency and duration of sleep (loss of righting reflex) in mice and the effect of hypnotics on sleep pattern of electroencephalogram were studied in conscious, freely moving mice with chronically implanted electrodes. The brain monoamine neurotransmitters levels in mice were measured by high performance liquid chromatography-electrochemical detection. The spontaneous locomotor activity was decreased by 56.7% and 80.2% in H1208 (5 and 25 mg x kg(-1), ip) treated mice, respectively. The loss of righting reflex was directly induced in mice after H1208 (60 mg x kg(-1), ip) administration. The non-rapid eye movement sleep increased significantly by 131% and 259%, respectively, within 3 hours after H1208 (30 and 60 mg x kg(-1), ip) administration. However, the rapid eye movement sleep decreased significantly. The contents of DA in the striatum and cortex and 5-HT in the cortex decreased significantly. These results demonstrated that H1208 has potent sedative and hypnotic effects, which may be closely related to the decreased contents of DA and 5-HT in mouse brain.
