Objective To investigate the correlation between the expression of human leukocyte antigen B27(HLA-B27)antigen and ankylosing spondylitis(AS),and its implications for the diagnosis and differential diagnosis of AS.Methods Flow cytometry was used to detect HLA-B27.354 suspected AS patients,35 patients final diagnosed with AS and 30 patients diagnosed with rheu-matoid arthritis(RA)were enrolled in the study.Results The positive rate of HLA-B27 in 354 patients with suspected AS was 22.0%,in patients diagnosed with AS was 85.7%,which was higher than the RA group(P <0.05).In AS patients,Males accoun-ted for 77.1%,females accounted for 22.9%,and the patients′age mainly concentrated in youth.The sensitivity and specificity of HLA-B27 test was 85.7% and 100.0% respectively in the diagnosis of AS.Conclusion HLA-B27 antigen detection is important for early diagnosis and differential diagnosis of AS patients.

Objective To investigate the effect of different stimulating culture conditions and detecting methods on the frequency of Th17 cells and to set up and optimize the experimental method for detecting the frequencies of human Th 17 cells in peripheral blood by flow cytometry (FCM ) .Methods The peripheral blood in the healthy people was performed the stimulating culture by phorbol myristate acetate (PMA) at different final concentrations(50 ,100 ,150 ,200 ,250 ,300 ng/mL) and ionomycin 1 μg/mL .The frequencies of Th17 cells were assessed by FCM after different stimulating time points (4 ,6 ,8 ,10 ,12 h) .The mean fluorescence in-tensity(MFI) and percentage of the ratio of CD4 positive cells on the cellular surface and inside cell membrane were measured be-fore and after PMA stimulation .Results The frequency of Th17 cells was highest with the good stimulation effect under the condi-tion of PMA 150 ng/mL and ionomycin1μg/mL stimulation for 6 h (P<0 .05) .MFI of CD4 inside cellular membrane after stimula-tion was lower than that in the cells with stimulation after labeling membrane surface CD 4(P<0 .05) ,and the Th17 cell frequencies and the ratio of CD4 positive cells were higher than those in the latter ,but the differences were not statistically significant (P>0 .05) .Conclusion After stimulating whole blood with the final concentration of PMA 150ng/mL and ionomycin1μg/mL for 6 h , measuring intracytoplasm CD4 and IL-17 levels is the simple and effective method for detecting the frequency of human Th 17 cells .

Objective To investigate the causes,diagnostic methods,prevention and cure of postmenopausal bleeding(PMB).Methods The clinical and pathological data of 210 PMB patients admitted in this hospital were retrospectively analyzed.Results The causes for PMB were benign diseases(69.5%),the most of which were infec- tious diseases(49.5%),non-organic disease(20.5%)and malignant tumor(10.0%).Compared with benign diseases and non-organic diseases,the attack age of malignant tumor was higher[(67.1?6.9)years old],menopausal dura- tion was longer(11.6?2.9)years,bleeding duration was longer[(157.6?26.4)days],and mucous membrane was obviously thickened[(14.6?3.2)mm](P0.05).Conclusion The main cause for PMB is benign diseases,followed by non-organic diseases.More attentions should be paid to the PMB patients with higher attack age,longer menopausal duration and bleeding dura- tion,and obviously thickened mucous membrane,so as to be precautions to the occurrence of malignant tumor.

Objective To investigate the dynamic variation of flavonoids contents in the flowers of Citrus grandis at different flowering periods. Methods The content of total flavonoids in the flowers of Citrus grandis was determined by means of ultraviolet-visible absorption spectroscopy ,and the contents of naringin and rhoifolin were determined by HPLC. Results The content of total flavonoids in the flowers during the flower withering period ,the young fruit period ,the blossom period,and the budding period was 306.90 mg.g-1,277.93 mg.g-1,215.55 mg.g-1 and 162.74 mg.g-1 respectively. The naringin content during the above four different periods was 246.31 mg.g-1,213.93 mg.g-1,175.94 mg.g-1 and 130.90 mg.g-1 respectively. The rhoifolin content during the four periods was unchanged. Conclusion The contents of total flavonoids and naringin in flowers of Citrus grandis during flower withering period are the highest.

Objective To understand the clinical features of candidemia.Methods A retrospective analysis was performed based on the data of 88 candidemia cases treated in Huashan Hospital during the period from 2007 to 2012.The clinical data were re-viewed in terms of species distribution,underlying diseases,clinical manifestations,treatment and outcomes.The prognostic factors were analyzed by chi-square test or Fisher exact probability test.Multivariate analysis was conducted by multiple Logis-tic regression.Results Candida albicans (40/88,45.5%)was the most common pathogen isolated from these candidemia ca-ses,followed by Candida tropicalis (20/88,22.7%),Candida parapsilosis (17/88,19.3%),Candida glabrata (10/88, 11 .4%),and Candida krusei (1/88,1 .1 %).Solid malignancy,diabetes,and surgical procedure were the most frequently identified underlying diseases.Fatal or deteriorative outcome was reported in 28 cases.The attributable mortality was 18.2%. Multivariate prognostic analysis indicated that presence of central venous catheter (OR:6.322,95% CI :1 .055-37.891 ,P =0.044)was independently correlated to increased mortality.Appropriate antifungal therapy was an independent predictor of de-creased overall mortality (OR:0.137,95% CI :0.039-0.480,P =0.002).Conclusions The pathogen distribution of candi-demia has changed slightly.Appropriate antifungal therapy plays a key role in the treatment of candidemia.

OBJECTIVE:To explore the comprehensive model for the prevention and treatment of community hypertension.METHODS:By questionnaire survey,the community hypertension target population was screened and the drug use in hypertensive patients was analyzed statistically.RESULTS:Of the 65 000 community residents investigated,1 250 were found to be hypertensive patients,with a total treatment rate of 80.0%;only 32.8% were treated with at least 2 kinds of drugs,and the overall blood pressure control efficacy was poor.CONCLUSION:The program of prevention and treatment for community hypertensive patients is conducive to patients' long term adherence to medication,scientific and rational drug use and effective and stable control of blood pressure.

Objective To investigate the causes and outcome of different treatment methods of iatrogenic rectovaginal fistula. Methods Clinical data of 52 patients with iatrogenic rectovaginal fistula were analyzed retrospectively. Results Twenty-two fistulae occurred after gynecological operation (42.3%), fourteen after obstetric injury (26.9%), thirteen after colorectal operation (25.0%) and three due to miscellaneous causes (5.8%). The fistulae were located in the lower rectum in 27 cases(51.9%), mid rectum in 10 cases(19.2%) and upper rectum in 15 cases(28.9%). They were treated by non-surgical treatment in 9 cases(17.3%), permanent diverting stoma(loop transverse colostomy) in 8 cases(15.4%), and surgical repair by various approaches in 35 cases(67.3%). The fistulae of all nine patients who received non-surgical treatment failed to heal. Eight patients who received permanent diverting stoma had symptomatic improvement without fistula healing. The overall cure rate of surgical repairs in 35 cases was 77.1%(27/35). The cure rates of trans-sphincteric (Mason′s operation), transanal, transabdominal, transperineal and transvaginal approaches were 100%(8/8), 100%(2/2), 83.3%(5/6), 0%(0/1) and 66.7%(12/18), respectively. The cure rate of Mason′s operation for the mid and lower rectovaginal fistulae was higher than that of transvaginal approach (100% vs 66.7%). Conclusions Iatrogenic rectovaginal fistula is caused by obstetric injury or injury of rectovaginal septum due to surgical mismanagement. Surgical repair is the only method that can cure rectovaginal fistulae. Mason′s operation is a favorable treatment method for the mid and lower (especially mid) rectovaginal fistulae.
