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 .

Chinese Journal of Primary Medicine and Pharmacy 2006;0(09):-
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 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 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 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.

Objective To evaluate the quality of different parts of agarwood formed by stimulation with biological induction method, thus to provide evidence for agarwood quality control. Methods The identification of agarwood and the determination of alcohol extracts from agarwood were achieved by the methods of Chinese Pharmacopeia. The determination of total chromones from agarwood was achieved by ultraviolet spectrophotometry(UVS), with aquilarone E as reference substance and 760 nm as the detective wavelength. Results The UVS method was stable within 5 h and the recovery rate was 95.71%(sR=2.09%). The average alcohol extract content of the outside part of the xylem of Aquilaria sinensis(Lour.) Gilg(part B) was 109.4 mg/g,which was higher than that (100 mg/g) of the Chinese Pharmacopoeia standard. The average content of total chromones was 15.73 mg/g. The rest identification results were accorded with the requirements of Chinese Pharmacopeia. The average alcohol extract content of the inside part of the xylem(part Z) was 47.6 mg/g, and the average content of total chromones was 2.66 mg/g. The rest identification results did not reach the requirements of Chinese Pharmacopeia. Conclusion The obtained part B of the agarwood meets the requirements of Chinese Pharmacopeia, while part Z has color changed and its quality has not yet reached the requirements. The results indicated that the biological induction method impacts Aquilaria sinensis xylem from outside to inside, and then the xylem grows into agarwood gradually.

Objective To explore the function of intensive care unit (ICU) in earthquake disaster. Mothod ICU in tent set by doctors from Second Military Medical University and Sichuan Jiangyou People's Hospital in 5·12 Wenchuan earthquake disaster. The value of ICU in tent was estimated by retrospective analysis of the experi-ence of emergency treatment for the critical injuries. Results Inside ICU in tent,there were many critical patients successfully rescued, including a soldier with septic shock, a casualty with traumatic shock during aftershock, a middle school student with crush injury and cornpartment syndrone, a peasant trapped under mined buildings for 168 hours with capillary leak syndrome, and a traffic victim and an aged patient with cardiac arrest. Patients after replatation of severed limb and patients after thoracic operation were monitored. Teaching rounds in the wards and logistics health drilling were made as well. Conclusions ICU in tent as a place where the critical casualties and patients after major operations could be rescued,cared for and monitored successfully,as well as the venue of teach-ing activity and logistics health drilling.
