Incidence of acute kidney injury ( AKI ) is increasing rapidly to epidemic proportions . Development of AKI is associated with increased morbidity , mortality and hospitalization costs .Currently available diagnostic tools are mostly insensitive for early diagnosis of AKI .Finding an early, reliable, easily reproducible , economical and accurate biomarker for AKI is a top research priority .In recent years , many serum and urinary proteins have been investigated as possible early markers of AKI .

Objective To explore and summarize the heart-shape anastomosis for hirschsprung′s disease .Methods Before the operation,the colon was cleaned thoroughly ,31 cases of this group (8 month-6 years old)underwent colonic pull-through and the dilated segment of colon was pulled out and resected.Normal colon and lower segment of rectum′s stomosis were stomosed as heart-shape (higher anterior and lower posterior).After replacing the colon and stomosis ,close the abdomen layer by layer.Results All 31 cases anus sphincter muscle were retained at most degree,so that retained their function of normal defecation .All 31 cases were healed and discharged, without one case with early complications as stomosis fistila,et al.No stomosis stenosis or other late period complication were found in 24 cases with long period follow-up.Conclusions Heart-shape stomosis is a good method for hirschsprung′s disease,especially fitful to the common type and short-segment type and long-segment type with diseased part in sigmoid colon .This method is easy,convenient,no special equipment was needed,easy to be publicized.

Objective Based on the Traditional Chinese Medicine Inheritance Support System (TCMISS) (V2.0), to analyze the point-selection rules in acupuncture-moxibustion prescriptions for gastroptosis indexed by China National Knowledge Infrastructure (CNKI), Wanfang and Vip databases, and to obtain novel prescriptions, for providing clinical references. Method Acupuncture-moxibustion prescriptions for gastroptosis indexed by CNKI, Wanfang and Vip databases were collected and filtered, and then input into the TCMISS. The prescriptions were analyzed by using data mining method. Result The frequency and core combination of the commonly-used acupoints were determined out of the 76 eligible prescriptions for gastroptosis, and 3 novel prescriptions were obtained. Conclusion The TCMISS is an important tool in mining and analyzing the point-selection rules in acupuncture-moxibustion treatment, and the new acupoint prescriptions generated by this system provide references to the treatment of gastroptosis.

Objective To investigate the effects of Xuebijing injection on the production of ICAM-1 and its counterreceptor(LFA-1)in ANP of rats at different time points.Methods ANP was induced by multiple points in- jection of 5% chenodeoxycholic acid into the pancreas,followed by ligation of pancreatic duct.Expressions of ICAM- 1 at different time points were assessed by immunohistochemistry method,the expressions of LAF-1 on neutrophils at different time points were detected by flow cytometer.The effect of Xuebijing injection was also evaluated by de- tecting the output of ascitic fluid,amylase level and histological changes in pancreas and lungs.Results The expres- sions of ICAM-1 in pancreas and lung of Xuebijing injection group decreased significantly than those in ANP group at most time points during the research period(P

Objective Cellular response to estradiol is mediated both by estrogen receptor (ER) binding to estrogen response element (ERE) and by non-nuclear actions like activation of signal transduction pathways such as mitogen activated protein kinase (MAPK) pathway. However, the signal transduction of estrogen involving phosphatidylinositol 3-kinase-protein kinase B (PI3K -PKB) is not clear in endometrial carcinoma. Our purpose was to study if PI3K-PKB signaling pathway could be activated rapidly by 17?-E 2 through non-nuclear action and also, whether PI3K inhibitor, LY294002, could inhibit such non-nuclear action of 17?-E 2 in endometrial carcinoma cell line Ishikawa. Methods Levels of phosphorylated PKB(Ser473 site, p-PKB) and total PKB were examined by western blotting in Ishikawa cells after stimulation with 17?-E 2 at 1?10 -6 mol/L for different time periods and at varied doses for 30 min. Optimal time and appropriate dose for 17?-E 2 to activate PKB in Ishikawa cells were observed. Inhibitory effect of LY294002 on activation of PKB induced by 17?-E 2 was also studied. p-PKB/PKB ratio was used to indicate levels of activation of PKB. Results p-PKB/PKB at 15 min (0.533?0.029) was significantly higher than the control (0.361?0.029, P 0.05, 0.05,

Epidemiological surveys show that folic acid can prevent prostate cancer, but fortified folic acid may increase the risk of the malignancy. The physician data queries from the National Cancer Institute of the USA describe folate as protective against prostate cancer, whereas its synthetic analog, folic acid, is considered to increase prostate cancer risk when taken at levels easily achievable by eating fortified food or taking over-the-counter supplements. We review the current literature to examine the effects of folate and folic acid on prostate cancer, help interpret previous epidemiologic data, and provide a clarification regarding the apparently opposing roles of folate for patients with prostate cancer. A literature search was conducted in Medline to identify studies investigating the effect of nutrition and specifically folate and folic acid on prostate carcinogenesis and progression. In addition, the National Health and Nutrition Examination Survey database was analyzed for the trends in serum folate levels before and after mandatory fortification. Folate likely plays a dual role in prostate carcinogenesis. There remains some conflicting epidemiologic evidence regarding folate and prostate cancer risk. However, there is growing experimental evidence that higher circulating folate levels can contribute to prostate cancer progression. Further research is needed to clarify these complex relationships.

Methods 86 patients with IGT were given metformin and exercise therapy,the range of glucose,BMI and symptoms improvement were observed before and after the therapy. Results After 6 months therapy,the fasting blood glucose and 2 h after oral administration of 75 g glucose levels were significantly reduced(P＜0.01＝,BMI reduced(P＜0.05＝.72 cases (83.7%)were back to normal glucose tolerance,14 cases maintained IGT(those unable to adhere to exercise and no diet controlled),0 case became DM. Conclusion Metformin and exercise therapy had good efficacy in curing IGT.

Objective To identify prognostic factors and imply the appropriate management of pulmonary metastases from osteosarcoma. Methods Data were obtained retrospectively from 99 osteosarcoma patients with pulmonary metastases who received systemic treatments and followed up in Department of Orthopedic Oncology of Peking University People's Hospital from January 2000 to July 2008. The mean followup time was 24.45 months (range, 13-91 months). The average age of the patients at diagnosis was 20.39 years (range, 7-68 years); the male female ratio was 65:34. All the patients had undergone resection of tumors, and 93 of them had received neoadjuvant chemotherapy. Pulmonary metastases were found in 16 patients at diagnosis of osteosarcoma, in 47 patients during chemotherapy and 36 patients after the whole treatment. The age of patients, the number of pulmonary metastases, the time of appearance of pulmonary metastases,extrapulmonary metastases, the response of primary tumor to chemotherapy and management of pulmonary metastases were analyzed. Results The interval between the diagnosis of osteosarcoma and pulmonary metastases ranged from 0 to 74 months with the mean time of 9.05 months. The 1-year, 2- and 5-year cumulative survival rates were 87.4%, 56.8% and 23.4% respectively in the study, with the median survival time of 25 months. Univariate analysis showed the significant factors included the time of appearance and the management of pulmonary metastases. Cox regression analysis revealed that the time of appearance of pulmonary metastases was the only prognostic factor. There was no significant difference between age, number of pulmonary metastases, extrapulmonary metastases and response of primary tumor to chemotherapy.Conclusion Characteristics related to the time of appearance of pulmonary metastases and surgical management especially as pulmonary resection appear to be more predictive of a successful outcome.

Background and purpose: Alveolar soft part sarcoma (ASPS) is a rare malignant neoplasm characterized by slow growth and indolent behavior, and most of the patients had metastases in diagnoses. This study was to define clinical features and assess prognostic factors of ASTS. Methods: Between January 2003 and December 2008, there were 15 patients with ASTS who received treatment and were followed up in the Department of Orthopedic Ontology of Peking University People's Hospital. We retrospectively analyzed the clinical factors of the disease related to prognosis: gender, age, tumor size, primary tumor site, metastatic sites, local recurrence, the roles of postoperative radiotherapy and postoperative chemotherapy. Resnlts: At a follow-up from 7 to 76 months, only 2 patients had local recurrences after excision, but there was a high incidence of pulmonary metastases. Only 6 patients achieved disease free survival, 5 patients died of metastases or other complications. The five-year overall survival rates was 41.7%, and the median survival time was 42.0 months. Univariate analysis and Cox regression analysis revealed that tumor size, tumor primary site and metastases at diagnoses were prognostic factors, but not gender and age, Conclusion: Alveolar soft part sarcoma is a high grade malignant soft tissue neoplasm with frequent metastases to lung, bone or brain. Tumor size, primary tumor site and metastases at diagnoses are some of the prognostic factors. Chemotherapy or radiotherapy after surgery have no benefit to the survival in our analysis. Further prospective studies are needed to clarify the best strategy for the treatment of ASPS.
