Objective To study the SRSF2 mutations in acute myeloid leukemia (AML) patients by using high-resolution melting analysis (HRMA). Methods PCR-HRMA analysis was performed to screen SRSF2 mutations in 140 cases with AML, and the direct DNA sequencing was used to confirm the HRMA results. Results Five percent (7/140) of AML patients were found with heterozygous SRSF2 mutations, including one case of P95R mutation, two case of P95L mutation, and four cases of P95H mutation, the above mutations were confirmed by direct DNA sequencing. The maximal sensitivity of HRMA in detecting SRSF2 mutation was close to 10%. There were no difference in gender, age and blood parameters among cases with or without SRSF2 mutations (P > 0.05). The overall survival (OS) of patients with SRSF2 mutations was inferior to those without SRSF2 mutations in AML patients (P=0.016). Conclusions HRMA analysis was a convenient, rapid, specific, high-throughput technique for scanning of SRSF2 gene mutations in AML patients. SRSF2 mutation may predict the adverse prognosis in AML patients.

The purpose of this study was to isolate and purify polysaccharide from Gynura divaricata and analyze its monosaccharide composition. A water-soluble crude polysaccharide was obtained by hot water extraction, ethanol precipitation and deproteinization after degreasing. The crude polysaccharide then purified with DEAE-Sepharose Fast Flow column chromatography and dialysis. The monosaccharide composition and structure were analyzed by HPLC, UV spectrophotometer and 1H-NMR. The results showed that the purity and molecular weight of GDPS-2 and GDPS-3 were 87.3%, 2.03 x 10(4) Da and 90.9%, 4.29 x 10(4) Da, respectively. The UV spectrophotometer and 1H-NMR data suggested that glycosidic bond of GDPS-2 and GDPS-3 were a type. Both GDPs-2 and GDPs-3 were homogeneous polysaccharides, and GDPs-2 was mainly composed of glucuronic acid and xylose at a molar ratio of 1.1:0.63. GDPs-3 was mainly composed of rhamnose, glucuronic acid, galactose, xylose and galacturonic acid at a molar ratio of 0.32:6.0:0.21:1.75:4.3.

Aim To evaluate the effects of pantoprazole on various experimental acute ulcer inrats and mice. Methods The model of a gastric ulcer of rats or mice was caused bystree- induced ulcer and ligatel pylurus-induced ulcer. Results & Conclusions At adose of 5, 10, 20 mg? kg-1 of Pantoprazole can markedly decrease the ulcer index ofstree-induced ulcer. Pantoprazole(4, 8, 16 mg? kg -1 ) significantly decrease the areaof ligated pylorus-induced gastric ulcer. It was also found that pantoprazole caninhibit the output of basic gastric acid.

Objective To investigate the clinical features of kidney transplantation of small pediatric donors to pediatric recipients.Method A retrospective analysis of 48 kidney transplants from small pediatric donors into pediatric recipients was performed.Result Based on the transplantation types,the patients were divided into two groups:the single kidney transplantation (SKT) group and the en bloc kidney transplantation (EBKT) group.SKT was performed on 36 patients and EBKT on 12 patients.In the SKT group,postoperative complications included vascular thrombosis in 1 case (2.8％),primary disease recurrence in 1 case (2.8％),ureteral stenosis in 1 case (2.8％),delayed graft function in 17 cases (47.3 ％) and acute rejection in 4 cases (11.1 ％).In the EBKT group,postoperative complications included vascular thrombosis in 4 cases (33.3％),urine leak in 2 cases (16.7％),delayed graft function in 2 cases (16.7％) and acute rejection in 2 cases (16.7％).At last follow-up,patient survivals were 100％ in both groups,whereas graft survival was 94.4％ (34/36) in the SKT group and 75％ (9/12) in the EBKT group.The mean serum creatinine in the SKT and EBKT group was (68.4 ± 22.1) and (55.8 ± 16.7) μmol/L,respectively.Conclusion Favorable outcomes can be obtained from transplantation from small pediatric donors.The use of this donor population for pediatric recipients should be encouraged.

Objective To investigate the effects of basal and early phase insulin secretion on plasma glucose level in type 2 diabetes. Methods Plasma glucose and true insulin levels were measured at 0, 30, 60, 120 min during standard meal test in 81 patients with type 2 diabetes. Insulin sensitivity index (ISI) and insulin secretion index (?I 30 /?G 30 ) were calculated for evaluating the insulin sensitivity. Contributions of basal and early insulin secretion to plasma glucose level were evaluated by multivariate regression analysis with SAS software. Results ISI and ?I 30 /?G 30 showed nearly equal effects on plasma glucose levels by multivariate regression analysis. Among insulin levels of different time points during standard meal test, basal and postprandial 60 min insulin levels played important roles in changes of plasma glucose levels. The effect of fasting insulin on the area under plasma glucose curve was stronger than that of ?I 30 /?G 30 . Conclusion Both basal and early insulin secretions greatly contribute to glycemic control.

Background:Nipple discharge cytology is a simple non-invasive method that may provide valuable information for detecting underlying malignancy.Several studies have investigated the diagnostic value of cytology in breast cancer patients with pathological nipple discharge,but the results have been highly variable.Herein we presented a systematic review and meta-analysis of published studies pertaining to the diagnostic capacity of nipple discharge cytology in patients with breast cancer.Methods:A systematic literature search was performed (Medline/PubMed,Embase,Cochrane Library databases,and Google Scholar) to identify studies that investigated the diagnostic capacity of cytology with regard to breast cancer in patients with pathologic nipple discharge.Two independent researchers identified articles that assessed the sensitivity and specificity of cytological evaluation for breast cancer detection in patients with pathologic nipple discharge published between January 2000 and October 2018.Articles were only included in the meta-analysis if they met predetermined criteria.The characteristics of each study and the data they yielded were summarized.Quality assessment of all articles included was performed using the Methodological Index for Non-randomized Studies Criteria (MINORS) and the Quality Assessment of Diagnostic Accuracy Study 2 (QUADAS-2).Heterogeneity was tested via Cochran Q test and the I2 statistic using Stata 12.0 and Meta-DiSc 1.4 software,and meta-analysis was performed.Results:A total of 286 articles were identified,of which 12 articles including a total of 1476 patients were deemed eligible for inclusion in the meta-analysis.A random-effects model assessing the capacity of nipple discharge cytology to predict breast cancer yielded pooled sensitivity 63％ (95％ confidence interval [CI]:53％-72％),specificity 95％ (95％ CI:87％-98％),positive likelihood ratio 12.35 (95 ％ CI:4.87-31.34),and negative likelihood ratio 0.39 (95 ％ CI:0.30-0.50).The diagnostic odds ratio was 31.88 (95％ CI:11.30-89.98).The area under the summary receiver operating characteristic curve was 0.79 (95％ CI:0.75-0.82).Conclusion:The current meta-analysis suggests that nipple discharge cytology is a useful diagnostic modality for detection of breast cancer in patients with pathological nipple discharge,with moderate sensitivity and high specificity.

Objective To evaluate the effect of endoscopic surgery for advanced malignant tumors in the nasal cavity and paranasal sinuses. Methods A retrospective data analysis was performed on 49 patients with advanced sinonasal tumors undergoing either an exclusive endoscopic approach or with a complemental approach from January 2004 to October 2010. Forty-nine patients were considered eligible for editions of the UICC staging systems). The histotypes encountered were squamous cell carcinoma 20 cases,adenocarcinoma 12 cases, mucosal melanoma 8 cases, olfactory neuroblastoma 6 cases, others 3 cases.These patients were operated on either by an exclusive endoscopic endonasal approach or with a complementary external approach; 36 patients received adjuvant radiotherapy or/and chemotherapy. The data were analyzed by Kaplan-Meier method and Log-rank test. Results The hemorrhage varied from 200 to 5000 ml during the operation, with an average of 600 ml. The post-operative complications were rare,1 patient lost her sight after operation, and no patient got infected at the site of operation (nor intracranial infection). After full amount of radiotherapy, no cerebrospinal fluid rhinorrhea was found. Four patients ( 8. 2% ) lost to follow-up. Sixteen patients died during the follow-up period, only three of them were without craniocerebral or orbital invasion. Four in 9 patients in the other pathological group (with the pathology of olfactory neuroblastoma or glioma etc) , which had a poor prognosis, died during the follow-up period, of them, 3 had definitive evidence of intracranial metastasis, and none of the nine patients had been followedup beyond 25 months. The 2 and 3 year disease-free rates were 34. 2% and 21.4% , and overall survival rates were 62. 5% and 58. 4% respectively. The T stage, margin status, and whether accepted post operative adjuvant therapy were significant factors in predicting disease recurrence(x2 were 7.7, 4. 9, 6. 8 respectively and P <0.05). Conclusions Now the endoscopic techniques with or without complementary approaches is an effective way for complete tumor removal. With postoperative complementary therapy, it provides a satisfactory survival rate with few side effects and better quality of life.
