OBJECTIVE：To study the therapeutic effect and safety of domestic tolterodine tartrate in treating patients with urinary bladder overactivity.METHODS：56 cases of bladder overactivity were divided into two groups randomly：tolterodine and control(oxybutynin)group.The course of treatment was 6 weeks.RESULTS：The effect of tolterodine in treatment group was comparable to that of oxybutynin in control group,however,the adverse reactions in oxybutynin group were more common than those in tolterodine group.CONCLUSION：Tolterodine is a suitable drug to treat bladder overactivity.

Objective To investigate the diagnostic value of endoscopic ultrasonography (EUS) for duodenal cysts.Methods Clinical manifestations, results of conventional gastroscopy and EUS, as well as follow-up, of patients with duodenal cysts were retrospectively analyzed.Results A total of 105 patients with duodenal cysts presented with no lesion-related symptoms, but displayed characteristic imaging changes under EUS, which could reveal the origin, size and nature of duodenal cysts, and differentiate it from other submucosal lesions.A maximum follow-up of 5 years showed no changes in duodenal cysts.Conclusion Duodenal cyst is a benign disease, and EUS plays a very important role in diagnosis of the disease.

Applying scientific literature in the teaching of nutrition and food hygiene is neces-sary. It can not only deepen students' understanding of the course and improve students' English level and scientific research ability, but also can improve teachers' professional skill. To improve the effi-ciency of teaching, teachers should choose literature close to the course and pay attention to selecting review literature and English literature. Textbook should be principal line of study during the teach-ing. Teachers should control the number and timing of explaining literature and grasp the complexity of literature. In order to facilitate students' understanding, teachers should make full use of related figures and tables.

Objective To evaluate the consistency of the test results detected by multiple automated hematology analyzers .Meth-ods The EP9-A2 guideline of NCCLS ,Passing-Bablok regression analysis and t test were adopted to compare the detection results of hemoglobin(HGB) ,hematocrit (HCT) ,red blood cell count(RBC) ,white blood cell count (WBC) and platelet(PLT) in 115 samples from patients by 5 automated haematology analyzers of the Sysmex XE-2100 ,the Sysmex XT-1800i ,the Sysmex XS-1000i , the Mindray BC-5300 and ABX pentra80 .The Sysmex XE-2100 was used as the reference instrument .Results In the detection of all the compared items including HGB ,HCT ,RBC ,WBC and PLT ,these automated hematology analyzers exhibited very good cor-relation(r>0 .97) ,whereas the individual parameters in 3 automated hematology analyzers appeared the proportional systematic differences and /or constant systematic differences ,including HCT in the sysmex XT-1800i ,HCT and RBC in the sysmex XS-1000i and RBC in the ABX pentra 80 .Conclusion The Passing-Bablok regression analysis combined with t test may identify the system-atic differences of the comparative results of 2 automated haematology analyzers ,the consistency of the comparative results of the automated hematology analyzers can not be evaluated by the simple correlation coefficient .

To survey the serum uric acid (SUA) levels and associated risk factors of hyperuricemia among youth and middle-aged residents in Guangzhou.A total of 1420 subjects,aged from 20 to 60 years,receiving health check-up at our hospital in 2010 were enrolled.The total prevalence of hyperuricemia was 22.04％,32.01％ in males and 14.07％ in females.The average SUA was (388 ±78) μmol/L in males and (288 ± 63) μ mol/L in females.The prevalence of hyperuricemia in males was 30.11％ before 40 years of age and 33.81％ between 40 and 60 years of age.The average level of SUA in males was significantly higher than that of females.logistic regression analysis showed that BUN,body mass index (BMI) and hypertriglyceridemia were the independent risk factors of disease while HDL-C and gender (females) the protective factors.

Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

To investigate the effect of Ca(2+)-sensing receptor (CaR) on Spermine-induced extracellular Ca(2+) influx and NO generation in human umbilical vein endothelial cells (HUVEC), the small interference RNA (siRNA) specifically targeting CaR gene was designed, synthesized and transfected into HUVEC according to the cDNA sequence of human CaR gene in GenBank. The transfection efficiency and the interference efficiency of CaR protein were determined by laser scanning confocal microscopy and Western blot, respectively. Intracellular Ca(2+) concentration ([Ca(2+)](i)) was measured by Fura-2/AM loading. The production of NO and the activity of endothelial nitric oxide synthase (eNOS) were determined by the DAF-FM diacetate (DAF-FM DA). Western blot results demonstrated that siRNA targeting the CaR specifically decreased the expression of CaR protein in CaR siRNA group 48 h after transfection (P < 0.05). At the same time, the Spermine-induced [Ca(2+)](i), eNOS activity and NO generation were also significantly reduced (P < 0.05) in CaR siRNA group compared with those in the untransfected or negative siRNA transfected group. In conclusion, the present study suggests that the CaR plays an important role in the Spermine-evoked process of extracellular Ca(2+) influx and NO generation in HUVEC.

Based on the transcriptome database of Salvia miltiorrhiza, specific primers were designed to clone a full-length cDNA of ent-kaurene oxidase synthase (SmKOL) using the RACE strategy. ORF Finder was used to find the open reading frame of SmKOL cDNA, and ClustalW has been performed to analysis the multiple amino acid sequence alignment. Phylogenetic tree has been constructed using MEGA 5.1. The transcription level of SmKOL from the hairy roots induced by elicitor methyl jasmonate (MeJA) was qualifiedby real-time quantitative PCR. The full length of SmKOL cDNA was of 1 884 bp nucleotides encoding 519 amino acids. The molecular weight of the SmKOL protein was about 58.88 kDa with isoelectric point (pI) of 7.62. Results of real-time quantitative PCR analyses indicated that the level of SmKOL mRNA expression in hairy roots was increased by elicitor oMeJA, and reached maximum in 36 h. The full-length cDNA of SmKOL was cloned from S. miltiorrhiza hairy root, which provides a target gene for further studies of its function, gibberellin biosynthesis and regulation of secondary metabolites.
