Objective To investigate the changes of serum immunoglobulin E(IgE)?T cell subgroups and cytokines in asthmatic children and to provide theoretical basis for the management of asthmatic children.Methods T cell subgroups were determined by indirect immuofluorence method mono clone antibody, the detection of IgE,interleukin(IL) 4,IL 6,IL 8,interferon ?(IFN ?) were done by ELISA method, and 20 normal children were served as control group.Results There were significant differences of CD3 +,CD4 +,CD4 +/CD8 + among the stages of exacerbation and convalescence of asthmatic children and control group.( P0.05).In the stage of convalescence the levels of IL 2,IFN ? were lower than control group( P0.05).Conclusions Allergic asthmatic patients between the exacerbation and convalescence stages still had immunologic imbalance,indicating increased number of CD4 +T cell(mainly Th2 cells)and hyperfunction;the insufficient number and(or) the inactivity of CD8 +T cell may induce immunological disturbance ,which is the major mechanism of asthmatic attacks. These findings suggest the patients in an abnormal immunological state should receive continuous anti allergic therapy.

Objective To evaluate the influence of laparoscopic uterine artery ligation on ovarian function. Methods In this retrospective study ,46 patients with laparoscopic myomectomy were selected and randomly divided into Ligation group and Non-Ligation group. The serum concentrations of follicular stimulating hormone (FSH), luteinizing hormone ( LH), estrogen ( E_2) were measured be-fore treatment and 1 ,3 ,6,12 months after treatment. Ovulating functions of ovary were monitored. All results were compared between two groups. Results All patients ovulated after 6 months. There were no significant differences between two groups in the levels of FSH, LH and E_2,.before and after treatment(P>0.05). Conclusions Laparoscopic uterine artery ligation do not affect ovarian function of pa-tients with uterine leiomyoma.

OBJECTIVE:To determine the contents of citric acid in fentanyl citrate raw materials and its injection by ion chro-matography. METHODS:The determination was performed on Thermo Dionex IonPacTM AS11-HC column with mobile phase con-sisted of potassium hydroxide (gradient elution) at the flow rate of 1.0 mL/min. The column temperature was 35 ℃,and sample size was 20 μL. The detector was suppressed conductivity detector. RESULTS:The linear range of citric acid were 0.1157-74.05 μg/mL(r=0.9995). The limit of quantitation was 0.1150 μg/mL,and the limit of detection was 0.0400 μg/mL;RSDs of preci-sion,stability and reproducibility tests were all lower than 2.0%;the average recoveries were 99.6%-101.5%(RSD=0.68%,n=9). CONCLUSIONS:The method is environmentally-friendly and simple with good accuracy and precision,and suitable for the contents determination of citric acid in fentanyl citrate raw materials and injection.

Objective To investigate the effects and safety of sequential treatments with methotrexate and mifepristone for ectopic pregnancy with fetal cardiac activity.Methods 4 cases of ectopic pregnancy with fetal car- diac activity in our hospital were given by sequential therapy with methotrexate and mifepristone.Serum?-HCG,liv- er function and renal function,blood routine and gastrointestinal response were observed.Results 4 cases of ectopic pregnancy with fetal cardiac activity with 1～4 periods of sequential treatments were cured.Except light gastroin- testinal response,and one had slight rise of serum ALT level and AST level,no one had rnyelosuppression and heavy hepatic injury.Conclusion The sequential therapy with methotrexate and mifepristone is an effective and safe method for the treatment to ectopic pregnancy with fetal cardiac activity.

Objective To investigate the techniques and influence factors for the respiratory navigator echo triggered whole-heart coronary MR angiography(WH-CMRA)and evaluate its application in visualizing coronary arteries and the image quality.Methods Ninety two volunteers were acquired with WH-CMRA at 3 T MR scanner using respiratory navigator-echo gated TFE sequence.Imaging quality was visually graded as 0—Ⅳ grade according to the visual inspection,average length,diameter and sharpness of coronary arteries.The correlation between the imaging quality and respiratory pattern,heart rate and navigator efficiency was analyzed.Results The imaging quality in 92 cases was that 28 were graded as Ⅳ, 53 were graded as Ⅲ,9 were graded as Ⅱ and 2 were graded as Ⅰ.The successful rate of scan was 88% (81/92).The imaging quality is mainly graded as Ⅳ when the heart rate was less than 75 beats per minute (bpm)and the sharpness of vessel was(48?11)%.When heart rate was more than 75 bpm,the image quality was mostly graded as Ⅲ and the sharpness was(33?15)%.The correlation between heart rate and imaging quality score was negative(r=-0.726,P0.05).Conclusion 3 T WH-CMRA technique could facilitated the visualization of whole coronary arteries at free breathing but having indications on heart rate.

OBJECTIVE: To investigate the genetic polymorphism of 12 STR loci in 240 Han population and evaluate application of the 12 STR loci systems in forensic cases. METHODS: 12 STR loci were amplified with Muti-loci STR PCR system, which were genotyped with electrophoresis separation on dPAGE. RESULTS: 12 STR loci system had high power of discrimination (DP) and it was suited for analysis of dated bloodstain especially. CONCLUSION The 12 STR loci systems is simple economy and practicality, which is useful in forensic identification and disputed paternity.

Objective To understand the current situation of knowledge on healthy life style among researchers.Data on the knowledge of healthy life style including healthy behavior,general status on health,physical activity and the use of sports facilities were gathered.In 2006,same questionnaire was used to compare with the previous data.Results The percentage of overall knowledge on health among permanent percentage of people who were aware of knowledge on"no-smoking"."intake less salt","maintaining healthy diet program"and"insisting on exercise"were 72.97%,93.11%,86.58% and 87.25% respectively in 2006,higher than 67.38%,89.74%,82.12% and 82.78% during the baseline(P＜0.01)study in the previous years.The percentage of correct answer about the healthy life style as diet and prevention of common diseases was higher among the permanent residents than those of temporary residents in 2006(P＜0.05).The sources of health-related knowledge were mainly from media,newspapers and through health education programs carried out in the community.Conclusion The Beijing municipal government and the community residential committees attached great importance to providing knowledge on

To explore the antagonistic effect of gingerols against the inflammation induced by lectin from Pinellia ternata. In this study, ELISA method was used to determine the effect of different extracts from gingerols on the release of inflammatory factor TNF-α from macrophages induced by lectin from P. ternata. The fluorescence probe was used to determine the effect of gingerols on the changes in ROS of macrophages induced by lectin from P. ternata. The western-blot method was applied to study the effect of gingerols on the increase in expression of cell receptor interacting protein RIP3 in macrophages induced by lectin from P. ternata. The scanning electron microscope (SEM) was used to study the effect of gingerols on morphological changes in macrophages induced by lectin from P. ternata. According to the results, gingerols can significantly inhibit the release of inflammatory factor from macrophages induced by lectin from P. ternata, ROS overproduction and increase in RIP3 expression. SEM results showed that gingerols can inhibit the cytomorphosis and necrocytosis induced by lectin from P. ternata. Fresh ginger's detoxication may be related to gingerols' effects in inhibiing release of inflammatory factor, ROS overproduction and increase in RIP3 expression caused by macrophages induced by lectin from P. ternata, which are mainly inflammatory development.
