Thirty strains of seven Candida species from CICC(China Center of Industrial Culture Collection)were studied. The strains were differentiated by ITS1 region PCR-SSCP fingerprinting analysis and ITS2 region PCR-SSCP fingerprinting analysis. Results showed that both ITS1 region and ITS2 region were able to differentiate the seven species of Candida clearly. Contrasting the maps and effects on the identification of Candida species of ITS1 region with that of ITS2 region, result indicated that on the identification of Candida species the application of ITS2 region was better than ITS1 region.

16S rDNA sequences of 30 Bacillus strains originally identified as Bacillus licheniformis from China Center of Industrial Culture Collection (CICC) were determined and analyzed. The results indicated that 24 strains are affiliated to Bacillus licheniformis;3 strains are affiliated to Bacillus cereus and 1 strain is affiliated to Bacillus subitilis;the similarity levels of 16S rDNA among the rest of 2 strains and other strains of Bacillus licheniformis,range from 96.4% to 97.4%,further tests are needed to clarify their position. Also we testified that 5' terminal 500bp of 16S rDNA is available to differentiate the strains of Bacillus licheniformis、Bacillus subtilis and Bacillus cereus.

This paper summarizes the progress on anti -tumor effect and its mechanism of Noni over the past decade.Plenty of tests indicated that noni juice , juice extracts, leaf and root extracts have anti -tumor effects.It can inhibit tumor growth through inducing tumor cell apoptosis ,activating host immune system ,inhibi-tion of angiogenesis and cyclooxygenase ,anti -oxidation and blocking carcinogen -DNA adduct formation.This paper provides a reference for the adjuvant therapy of anticancer drugs and food form Noni .

Objective To investigate the mechanism for rhein to improve the insulin sensitivity in diabetes mellitus. Methods Male Wistar rats were randomly divided into normal control group (NC,n=15) and diabetic group (DM,n=40) induced by STZ and high-fat diet.Diabetic rats were randomly divided into diabetic control group (DM-C,n=15) and diabetic group treated with rhein (DM-T,n=15).Then DM-T group was given intragastric administration with rhein at the dose of 100 mg/ (kg-1?d-1) for 11 weeks.FBG,fasting serum insulin (FIns),triglyceride (TG),total cholesterol (TC),insulin sensitivity index (ISI) and other biochemical parameters in each group were measured.The protein expressions of PPAR-? and GluT-4 were determined by immunohistochemistry and Western blot. Results At the end of the 17th week,compared with NC group,DM-C group showed higher FBG and TG,lower ISI,lower protein expressions of PPAR-? and GluT-4 in the adipose tissue.Compared with DM-C group,DM-T group showed lower FBG [(15.73?3.08 vs 22.57?3.23) mmol/l,P

Objective To investigate the clinical application of CT perfusion imaging in assessing the hemodynamic changes in patients with small hepatocellular carcinoma (<5 cm) before and after transcatheter arterial chemoembolization (TACE). Methods Twelve patients with small hepatocellular carcinoma were enrolled in this study. CT perfusion imaging of the liver was performed 1 - 2 days before and 3 - 4 weeks after TACE. By using the perfusion parameters the hemodynamics of the preoperative and postoperative tumor tissue, the hemodynamics of the preoperative tumor tissue and the normal tissue, and the hemodynamics of the postoperative active tumor tissue and the normal tissue were determined , and the results were compared between each other. Results Before TACE, the blood flow (BF), hepatic arterial fraction (HAF), hepatic arterial perfusion (HAP) and permeability of surface (PS) in the tumor tissue were significantly higher than those in the normal tissue (P < 0.01), while after TACE all the perfusion parameters except blood volume (BV) were significantly decreased in the tumor tissue (P < 0.01). After TACE, BF, PS, HAF and HAP in the activity tumor tissue were increased more than those in the normal tissue (P < 0.05). Conclusion CT perfusion imaging is of great clinical value in diagnosing < 5 cm hepatocellular carcinoma , in evaluating the hemodynamic changes after TACE and in demonstrating the activity of the residual tumor tissue.

Objective To optimize the extraction process of neohesperidin in Fructus Aurantii Immaturus.Methods The optimum proess was investigated by L9(34) orthogonal design with the content of neohesperidin as the observation index.Results Extraction times were the main factors for neohesperidin extraction.The optimal process condition was as follows:adding 6-fold 70 %ethanol,extracting for 3 times,one hour for each extraction.Conclusion The optimal extraction technology of neohesperidin in Fructus Aurantii Immaturus is stable and reliable.

Objective To analyze the clinical efficacy of balloon occlusion of distal abdominal aorta for patients with pernicious placenta previa and placenta accreta.Methods Data of 72 patients with pernicious placenta previa and placenta accreta were retrospectively analyzed.There were 53 cases (occlusion group) reserved balloon occlusion in abdominal aorta before cesarean section,which can temporarily blocked abdominal aortic blood flow during operation.The other 19 cases (non-occlusion group) underwent cesarean section without balloon occlusion of abdominal aorta.The intraoperative,post operative situations and the birth state of newborn of the two groups were compared.Results The bleeding,blood transfusion and hysterectomy rate during the operation in occlusion group were less than those in non-occlusion group (all P＜ 0.05).Differences of the rate of postoperative transferring to intensive care unit (ICU) and the time in ICU were statistically significant between two groups (both P ＜0.05).No statistical difference of operation time,postoperative total hospital stay time and the rate of postoperative infection was found between two groups (both P＞0.05).There was no statistical difference of newborns weight and Apgar scores (5 min and 10 min after birth) between two groups (all P＞0.05).Conclusion The balloon occlusion of distal abdominal aorta in cesarean section for patients with pernicious placenta previa and placenta accreta is safe and feasible,which can effectively reduce the intraoperative bleeding,the blood transfusion and the risk of hysterectomy.

Objective: To explore the impact of renal function injury on diagnostic value of NT-proBNP in patients with heart failure (HF).
Methods: A total of 420 patients with cardiovascular disease at (50-75) years of age were divided into 2 groups based on left ventricular ejection fraction (LVEF): Control group, the patients with normal cardiac function, LVEF≥40%,n=232 and HF group, LVEF<40%,n=188. According to estimated glomerular ifltration rate (eGFR), each group contained 4 subgroups by Normal renal function (eGFR≥90 ml/min·1.73m2), Mild renal injury (90>eGFR≥60 ml/min·1.73m2), Moderate renal injury (60>eGFR≥30 ml/min·1.73m2) and Severe renal injury (eGFR<30 ml/min·1.73m2). The changes of NT-proBNP level at different subgroups were observed and the optimal cut-off values of NT-proBNP for HF diagnosis were measured.
Results: Compared with Control group, HF group had increased blood level of NT-proBNP,P<0.05; NT-proBNP level was negatively related to eGFR (in all patients:r=-0.664, in Control group:r=-0.686 and in HF group:r=-0.721,P<0.05). Within Control group, NT-proBNP level was similar between Normal renal function and Mild renal injury subgroups,P>0.05, while it was much higher in Moderate and Severe renal injury subgroups than Normal renal function subgroup,P<0.05. Within HF group, Severe renal injury subgroup had increased NT-proBNP level than other subgroups,P<0.05. The best cut-off value of NT-proBNP for HF diagnosis in patients with normal or mild renal injury was 1070 pg/mL (sensitivity: 91.8% and speciifcity 72.6%); with moderate renal injury was 7121 pg/mL (sensitivity: 80.2% and speciifcity: 89.7%); with severe renal injury was 33344 pg/mL (sensitivity: 83.3% and speciifcity: 80%).
Conclusion: Moderate to severe renal function injury could increase circulating level of NT-proBNP and therefore, the cut-off value of NT-proBNP for HF diagnosis should be elevated accordingly in patients of HF combing renal injury.
