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.

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.

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.

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 assess the frequency of different subtype of spinocerebellar ataxias (SCAs) in Chinese Han population. Methods The nueleotide repeat mutations of SCA1, SCA2, SCA3/ MJD, SCA6, SCAT, SCA8, SCA10, SCA12, SCA17 and dentatorubral-pallidoluysian atrophy (DRPLA) were detected by the polymerase chain reaction (PCR), denaturing polyacrylamide gel electrophoresis (PAGE), Southern blot, recombinant DNA technology by T-vector cloning and direct sequencing technique in a cohort of 559 Mainland Chinese patients affected by spinocerebellar ataxia, including 363 families with autosomal dominant SCA (AD-SCA) and 196 sporadic cases. Results Among the 363 AD-SCA families, 15 families (4. 13%) were positive for SCA1, 26 (7. 16%) for SCA2, 187 (51.52%) for SCA3/MJD, 6 (1.65%) for SCA6, 7 (1.93%) for SCA7, 1 (0. 28%) for SCA12 and 1 (0. 28%) positive for SCA17; 120(33. 06%) were negative for all the tested SCAs. There were 2 (1.02%) SCAI, 3 (1.53%) SCA2, 15 (7. 65%) SCA3/MJD, 3 (1.53%) SCA6 and 173 (88.27%) not identified in the 196 sporadic SCA patients. None of the SCA8, SCA10 and DRPLA mutation was found. Conclusions SCA3/MJD is a substantially common subtype of AD-SCAs and sporadic SCA in Chinese Han patients with SCAs, subsequently followed by SCA2, SCA1, SCAT and SCA6; SCA12 and SCA17 are uncommon subtypes, while SCA8, SCA10, and DRPLA are rare, if not absent. SCA17 subtype was initially identified in mailand China. Some other genes might be causative in those unidentified AD-SCA pedigrees, and other etiological factors besides genetic cause might contribute for those sporadic cases.

Objective To undertake an updated genetic spectrum analysis in patients with hereditary spinocerebellar ataxia (SCA) in mainland China. Methods SCA 1, 2, 3, 6, 7, 8, 10, 12, 17 and dentatorubral-pallidoluysian atrophy (DRPLA) nucleotide repeat mutations were detected in 430 families with autosomal dominant SCA (ADCA) and 237 patients with sporadic ataxias by PCR and DNA sequencing. Subsequently, point and Indel (Insertion/deletion) mutation analyses of SCA5, SCA11, SCA13, SCA14, SCA15/16/29, SCA27, SCA31 and SCA35 were detected in 91 families with ADCA and 196 patients with sporadic ataxias excluded from SCA1, 2, 3, 6, 7, 8, 10, 12, 17 and DRPLA genotypes via PCR and Denaturing High Performance Liquid Chromatography (PCR-DHPLC), Multiplex ligation-dependent probe amplification and DNA direct sequencing analysis. Results Among the 430 ADCA families, there were 25 SCA1 (5.81%), 27 SCA2 (6.28%), 267 SCA3/MJD (62.09%), 8 SCA6 (1.86%), 8 SCA7 (1.86%), 1 SCA12 (0.23%), 1 SCA17 (0.23%) and 2 SCA35 (0.47%), and the remaining 91 families (21.16%) were genetically unidentified. Among the 237 sporadic SCA patients, there were 6 SCA1 (2.53%), 9 SCA2 (3.80%), 23 SCA3/MJD (9.70%) and 3 SCA6 (1.27%), and the remaining 196 (82.7%) were genetically unidentified. No pathogenic point mutation causing SCA5, SCA11, SCA13, SCA14, SCA27 or SCA31 subtypes was found. Conclusion SCA3/MJD is substantially the most common subtype in patients with ADCA and sporadic forms in mainland China, followed by SCA2, SCA1, SCA6 and SCA7. While SCA12, SCA17 and SCA35 are seldom found, SCA5, SCA8, SCA10, SCA11, SCA13, SCA27, SCA31 and DRPLA are very rare. The high proportion of genetically unidentified cases further verify that SCAs are of highly genetic heterogeneity, suggesting that other disease-causing genes might be involved in the negative ADCA pedigrees, and other etiological factors may involve in those sporadic cases other than genetics.
