Objective To establish a SYBR Green based real-time fluorescence quantitative PCR method for detecting human Annexin Ⅱ mRNA expression,and to detect the level of Annexin Ⅱ mRNA in human breast cancer cells MCF-7 and MDA-MB-231.Methods The specific primers were designed according to the conserved sequence of human Annexin Ⅱ gene.Total RNAs were extracted from human breast cancer cells(MCF-7,MDA-MB-231),then RNAs were transcribed reversely into cDNAs.The plasmid standards were constructed.The relative expression levels of human Annexin Ⅱ mRNA in human breast cancer cells were detected by this method.Results The square(r2 )of correlation coefficient of the standard curve in this method was 0.997,the melting curve analysis showed the single peak.The the intra-batch and inter-batch variable coefficients in the pGM-T Annexin Ⅱplasmid standard substance were 6.2%,7.8% and 9.1%,12.3% respectively.The further study indicated that AnnexinⅡ mRNA in MDA-MB-231 was higher than that in MCF-7(P<0.01).Conclusion The established SYBR Green real time fluorescence quan-titative PCR method for detecting human AnnexinⅡ is of good specificity and repeatability and can be used for quantitatively detec-ting AnnexinⅡ mRNA in breast cancer cells.

Objective To study the curative effect of combing montelukast with inhaled corticosteroids in the treatment of cough variant asthma .Methods According to diagnosis standard guideline for diagnosis and treatment of cough in CVA,84 cases of CVA patients were chosen and divided into the treatment group (n=42)and the control group(n=42).The control group were treated with inhaled corticosteroid Budesonide .The treatment group was given monelukast based on the treatment in control group .And the clinical effects of two groups ,recurrence and the lung function index were observed .Results The total efficiency of treatment of the control group was 73.8%,and the treatment group was 95.0%.The total effective rate of observation group was apparently higher than that of the control group(χ2 =6.46,P<0.05).The lung function of the treatment group compared to the control group was significantly increased(t=2.873,P<0.05).Conclusion Montelukast combined with Glucocorticoid in the treatment of CVA can effectively improve the cure rate ,reduce the recurrence ,which can be widely used in clinical treatment .

Objective To investigate the association of the polymorphism of endothelial nitric oxide synthase (eNOS) gene 27bp variable number of tandem repeats (VNTR) with essential hypertension (EH) and type 2 diabetes mellitus (DM) in Chinese population. Methods (1) Genotypes were determined by polymerase chain reaction (PCR)-agarose gel electrophoresis. (2) Fasting serum nitric oxide metabolites (NOx) were measured by nitrate reductase. (3) During oral glucose tolerance test (OGTT) serum immunoreactive insulin (IRI) and C peptide (CP) were measured by radioimmunoassay. Results (1) The frequenciesofaalleleinEHandtype2DMgroupwere significantly higher than that in control group (0.109 vs 0.051; 0.129vs 0.051, P

The policy of“licensed doctors'multi-site clinical practice” aims to provide patients with a better access to quali-ty medical and health resources.Patient's understanding and support indicates the executive condition of the implementation of the pol-icy and it can also promote the implementation of the policy to a certain extant .In this study , the questionnaire survey and statistical tools were used to investigate the differences in their attitudes to the policy .

Objective To observe the clinical efficacy of acupuncture-moxibustion in treating early-stage glandular cystitis. Method Forty patients diagnosed with glandular cystitis by cystoscopy and biopsy were divided into a treatment group and a control group, 20 cases in each group. The treatment group was intervened by acupuncture-moxibustion, while the control group was by intravesical perfusion chemotherapy. The clinical efficacies were compared between the two groups. Result The therapeutic efficacy of the treatment group was significantly superior to that of the control group (P<0.05), and the relapse rate confirmed by using cystoscopy and biopsy was significantly lower in the treatment group than in the control group (P<0.05). Conclusion Acupuncture-moxibustion can enhance the clinical efficacy in treating early-stage glandular cystitis.

Objective To evaluate the performance of UW2000 automatic urine system .Methods Using UW2000 automatic u‐rine system ,to evaluate intra ,inter batch precision ,linear ,carryover ,and the accuracy of the urine visible components(RBC ,WBC);at the same time intra ,inter batch precision and accuracy of of urine dry chemistry component .Results The within‐run coefficients of variation(CV% ) of RBC in high ,middle and low‐value samples were 15 .6% ,6 .8% ,20 .3% ,WBC were 16 .4% ,10 .5% ,24 .6% , respectively .Inter‐run precision of variation(CV% ) of RBC in middle and low‐value were 12 .8% ,13 .2% ,WBC were 15 .3% , 22 .8% ,respectively .The correlation coefficient of RBC was 0 .991 and the linear range was 88-19 513/μL .The correlation coeffi‐cient of WBC was 0 .997 and the linear range was 7-8 254/μL .And carryover rate was 0 .00% for RBC and 0 .06% for WBC ;The coefficient of UW2000 and microscopy on RBC and WBC were 0 .992 ,0 .995 .Within‐run precision ,inter‐run precision and accuracy for urine dry chemical composition of high ,low controls were all within the requirements of standards .Conclusion UW2000 auto‐matic urine analyzer workstation was not only save manpower ,but also with high detection speed and save cost .Importantly ,the re‐sults are reliability .In addition ,it could meet the working requirement in the general hospital ,and has great application value .

17α-hydroxylase/17,20-lyase deficiency (17OHD) is a rare cause of congenital adrenal hyperplasia.The patient predominantly presents with low-renin hypertension,hypokalemia,lack of secondary sexual development,and in women with primary amenorrhea,in male with pseudohermaphroditism.We herewith analyse the clinical features of a case of 17OHD diagnosed by gene sequencing.And the etiology,clinical manifestations,genetic features,diagnosis and treatment for 17OHD were reviewed.

Fulminant type 1 diabetes (FT1 D) has been identified as a new subtype of idiopathic diabetes.FT1D is characterized by abrupt and complete destruction of pancreatic β cells,with diabetic ketosis or diabetic ketoacidosis occurring within a week after the onset of hyperglycemic symptoms.At the time of initial presentation,plasma glucose level is increased,with near normal HbA1C.Serum pancreatic enzyme is elevated in the majority of patients with FT1D.Flu-like symptoms or gastrointestinal symptoms precede disease onset in most of patients.However,the pathogenesis of this disease remains unclear.Factors such as viral infection,autoimmune,and pregnancy based on the background of genes may account for FT1D.We herewith report two cases of FT1 D,and review its clinical features,diagnosis,and treatment.

Objective To explore the CT and MR imaging characteristics of intracranial melanomas. Methods CT and MRI characteristics in five patients admitted to our hospital from June 1993 to June 2000 and diagnosed as intracranial melanomas were retrospectively analyzed. Results There were two cases of primary melanoma and three cases of secondary melanoma. All the cases were examined by CT. The lesions presented as high density in 4 cases, and low density in only 1 case. Four cases were examined by MRI. Short T 1 and short T 2 signals were found in 3 cases, and slightly long T 1 and short T 2 signal was found in 1 case. Conclusion There are some special characteristics of melanomas on the MR imaging, which are helpful to ensure the diagnosis and distinguish the primary melanomas from secondary melanomas.
