Objective: To study the effect of tripterygium wilfordii polyglycosidium (TWP) on atopie dermatitis (AD) by detecting the expression of IL-2,IL-4,IFN-γ and IL-IO mRNA. Methods: RT-RCR was used to detect the mRNA of IL-2,IL-4, IFN-γ and IL-10 in peripheral blood mononuelear cells (PBMC)of AD cultured with different concentrations of TWP.ResuRs:(1)The expression of IL-2 was significantly different between the high concentration group and other groups(P＜0.05 or P＜0.01 ), and between the control group and the middle concentration group (P＜0.01). (2)The expression of IL-4 was significantly different between the three different concentration groups (P＜0.01 ). (3) The expression of IFN-γmRNA was significantly different between the high concentration group and the control, the low, the middle concentration groups (P＜0.05 or P＜0.01 ). (4)There was no significant difference in expression of IL-10 mRNA between the high concentration group and the middle concentration group (P＞0.05), there was significant difference among the other groups (P＜0.05 or P＜0.01).Conclusion: TWP can suppress the expression of IL-2, IL-4, IFN-γand IL-10 mRNA, but the low concentration of TWP can suppress the high-level expression of IL-4 and IL-10mRNA in vitro.

OBJECTIVE To investigate the hospital acquired MRSA infection death cases and drug-resistance to improve the proper clinical utilization of antibiotics.METHODS The clinical data of the death cases in ICU wards from Mar 2008 to Jun 2008,and the drug sensitivity and resistance results of MRSA from Jan 2007 to Dec 2008 were analyzed retrospectively.RESULTS MRSA isolated from all of the three death cases were susceptible to vancomycin and unsusceptible to other antibiotics.Thirty MRSA strains were isolated from Jan 2007 to Dec 2008.Drug sensitivity test showed 100% drug-resistance rate to penicillin,erythromycin,cefazolin and oxacillin;66.7%-87.0% drug-resistance rate to ciprofloxacin,clindamycin,levofloxacin,and sulfamethoxazole compound.CONCLUSIONS High drug-resistance rate of MRSA to commonly used antibiotics is found.MRSA is usually infected in patients with malnutrition,major surgery or infants long term using ventilator.Sensitive antibiotics should be used in early time and regulations from aspects of hospital infection control,medical administration and nursing management also be carried out to prevent and control the prevalence of MRSA bacteria.

Objective To evaluate the effect of group cooperative learning on the experimental teaching of obstetrics and gynecology nursing.Methods We chose 113 undergraduate nursing students,using the traditional self-learning mode in the experimental teaching of cleaning and disinfection of the vulva and the group cooperative learning mode in the experimental teaching of vaginal douching.Their practical manipulations of the nursing skills by the two teaching modes were compared.A self-designed questionnaire was adopted to investigate the student's attitude to the group cooperative learning.Results The examination achievement by the group cooperative learning was better than that by the traditional self-learning,(Z=-4.986,P<0.001).89.4%of the students approved of the group cooperative learning.Conclusion The group cooperative learning may improve the effects of experimental training,contribute to the cooperative spirits of students,and also make full use of the human resources in teaching.

Objective To evaluate the morbidity and the influence factors of the geriatric syndrome in the elderly inpatients. Methods The characteristics of comprehensive geriatric assessment of180 elderly inpatients (83 male and 97 female) with age older than 65 in geriatric department from November 2014 to November 2015 were analyzed. Results Of 180 elderly patients, the incidences of visual loss, multiple co-morbidity, polypharmacy, impairment in activities of daily living, urinary incontinence, chronic constipation and chronic pain were 86.11%(155/180), 85.56%(154/180), 82.78%(149/180), 56.11%(101/180), 49.44%(89/180), 46.67%(75/180) and 42.22%(76/180). Female patients had more incidences compared with male in urinary incontinence [56.70%(55/97) vs. 40.96%(34/83)], chronic pain [56.70% (55/97) vs. 25.30%(21/83)] , impairment in activities of daily living [64.95%(63/97) vs. 45.78%(38/83)] and high risk of falling [43.30%(42/97) vs. 21.69%(18/83)], and there were significant differences (P<0.05). In addition, it was found that with the increasing of age, the incidences of hearing loss and chronic constipation, as well as medications were accordingly higher. When the patients′education level was higher, the incidences of urinary incontinence and impairment in activities of daily living were generally declined. Compared with non-diabetes mellitus group, diabetes mellitus group had higher incidences of comorbidities, multiple co-morbidity, medications, polypharmacy and impairment in activities of daily living:(10.59 ± 3.72) kinds vs. (8.29 ± 4.03) kinds, 94.59%(105/111) vs. 71.01%(49/69), (10.07 ± 3.77) kinds vs. (6.87 ± 3.07) kinds, 89.19%(99/111) vs. 72.46%(50/69), 62.16%(69/111) vs. 46.38% (32/69). With the increasing of the numbers of diabetes- related chronic complications, the incidences of visual loss, chronic constipation and multiple co- morbidity, comorbidities and medications were higher (P<0.05). Conclusions Geriatric syndrome such as visual loss, multiple co- morbidity, polypharmacy, impairment in activities of daily living and urinary incontinence are very common in the elderly inpatients. Elderly patients with diabetes mellitus are much easier to suffer from geriatric syndrome such as multiple co-morbidity, polypharmacy and impairment in activities of daily living.

ObjectiveTo detect the mutations of GJB3 and GJB4 genes in two sporadic cases of erythrokeratodermia variabilis(EKV).MethodsGenomic DNA was extracted from two sporadic patients with EKV,their family members,and 100 normal human controls.All the exons and adjacent splice sites of GJB3 and GJB4 genes were amplified by PCR.Mutation scanning was carried out via direct bidirectional DNA sequencing.ResultsA G134C mutation was found at the GJB3 gene in patient 1,which caused a substitution of glycine by alanine at codon 45 (G45A).No mutation was found in the GJB4 gene in case 1 or GJB3 and GJB4 genes in case 2.ConclusionA missence mutation G45A in GJB3 gene is found in a patient with EKV.

In this study, metabolism of nobiletin in rats was studied using ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS). As a result, seven major metabolites were found in bile, urine and serum of rats. Three phase I products were assigned to be demethyl and di-demethyl products, and other four phase II products were assigned to be glucuronic and sulfonic conjugates. The four phase II metabolites were reported for the first time. Among the metabolites found in the present study, the glucuronic conjugates of demethyl-nobiletin played a predominant role in the metabolic pathway, indicating that its potential role for glucuronidation-related factors, such as gene polymorphism, drug-drug interaction, etc., in changing the active and toxic effect of nobiletin and that it should be paid more attention in further development.

Objective To compare effect of three therapies( modified constraint-induced movement therapy (mCIMT), constraint-induced movement therapy (CIMT) and Bobath therapies)on the recovery of motor function in upper-extremities of patients with apoplexy hemiparalysis. Methods Fifty-seven patients with apoplexy hemiparalysis were randomly divided into CIMT treatment group ( n = 19), mCIMT group (n = 19) and Bobath group (n = 19). Patients in Bobath group exercised 2 h/d, 5 d/week for 6 weeks. CIMT group and mCIMT group had restriction of movement at the unimpaired upper extremity by placing it in a sling a whole day for training using impaired extremity. Patients in CIMT treatment group exercised 6 h/d,5 days a week for 2 weeks in a row; mCIMT treatment group exercised for 1 h/d, 3 days a week, and also exercised in daily life at least 2 hours every day, for ten consecutive weeks. The patients in all three groups were assessed for upper-extremities motor function using FMA of Fugl-Meyer, for recovery of upperextremities motor speed using STEF and for recovery of daily ability at respective time-points of pre-treatment and the second week, sixth week and tenth week of post-treatment. Results In 3 assessments in the 3 groups there was no obvious change before treatment, while the FMA score was 45. 2 ± 5.1 (F = 1. 107 ,P =0. 382), BI score was 63. 1 ± 10. 3 ( F = 0. 930, P = 0. 401 ), STEF score was 63.4 ± 8.6 ( F = 1. 843, P =0. 168). At the second week, sixth week and tenth week of the treatment, the difference of assessment in the three groups was significant. The improvement in CIMT group was better after 2 weeks treatment compared with Bobath and mCIMT group, while the Bobath group showed better results than mCIMT group did after 6 weeks treatment. After 10 weeks treatment, the FMA, STEF in mCIMT and CIMT groups were improved better than Bobath group, while the BI score in mCIMT group was better than that in Bobath and CIMT group. Conclusions The mCIMT and CIMT therapy are better in improving the upper limb function in stroke patients compared with Bobath, while the mCIMT therapy is more effective in improving the abilities of daily life in stroke patients compared with the other two treatments.

Objective To investigate the diagnostic value of using magnetic resonance imaging (MRI) and transabdominal sonography in antenatal placental adhesive disorders,to provide a theoretical basis for choosing different delivery ways.Methods 75 patients were assessed the placenta structure with MRI and transabdominal sonography.The patients were divided into two groups according placenta in the anterior and posterior uterus(41 cases in anterior group,34 cases in posterior group).Observed relationship between placenta and myometrium,compared imaging finding with pathological or clinical results.Results The sensitivity in diagnosis of placenta in the anterior uterine group was 75.0％ with MRI and 95.0％ for transabdominal Sonography (P＜ 0.05).The specificity was 90.1 ％ with MRI and 80.9 ％ for transabdominal sonography (P＞0.05).The sensitivity in diagnosis of placenta in the posterior uterine group was 95.8％ with MRI and 66.7 ％ for transabdominal Sonography(P＜0.05).The specificity was 90.0％ with MRI and 70.0％ for sonography (P＜0.05).There were significantly difference the imaging feature of uterine bulging,increased subplacental vascularity and dark intraplacental bands on T2-weighted images in placenta accrete group and nonplacenta accretegroup (P＞0.05).Conclusion Both sonography and MRI have fairly good sensitivity and imaging features for prenatal diagnosis of placenta accrete.Especially,MRI is an excellent tool for diagnosis of placenta accrete in the posterior uterine.

Objective To evaluate the left ventricular twist in patients with coronary heart disease (CHD) with two-dimensional strain echocardiography (2DSE). Methods Thirty-eight patients with CHD and 31 control subjects proved with selected coronary angiography were enrolled. Two-dimensional images from LV short-axis views at the levels of mitral annulus and apex in 3 continuous cardiac cycles were recorded. LV ejection fraction (LVEF) was calculated with bi-plane Simpson's method, torsion and torsional rate were obtained in each plane, and the corresponding curve was accessed. Results No statistical difference of conventional echocardiographic parameters such as LV diameter, left atria diameter, LVEF, FS, E/A and E-wave deceleration time were detected, while significant difference of torsional direction (P＜0.01) and global torsion rate (P＜0.05) were found between the two groups. Conclusion The global torsional rate and torsional direction have higher sensitivity than conventional echocardiography in the diagnosis of CHD.

Objective To explore the clinical significance of the disagreement between transmitral pulsed wave Doppler (PWD) and mitral annulus Doppler tissue imaging (DTI) in the estimation of left ventricular (LV) filling pressures. Methods One hundred and eighty-two sinus rhythm patients without arrhythmia, congenital heart disease and valvular disease underwent routine echocardiography and synchronous electrocardiogram for assessment of LV function. Early and late diastolic velocities of LV, which were composed of e and a waves, were recorded using DTI at the mitral annulus. Six sites at the mitral annuli were selected corresponding to the septal, lateral, anterior septal, posterior, inferior, and anterior walls of LV from apical 4-, 3-and 2-chamber views. Transmitral diastolic flow velocity, which was represented by E and A wave, was measured with PWD from apical 4-chamber view. Ratio of early and late diastolic transmitral valve (MV-E/A), ratio of DTI-e/a-ann and ratio of E/e-ann were calculated, respectively. The mean value of e-ann from the above 6 sites was selected to describe the early diastolic velocities of mitral annular. Results According to the results of MV-E/A ratio and DTI-e/a-ann ratios of the 6 sites, these 182 patients were divided into 4 groups: groupⅠ(n=68): MV-E/A＜1.0, DTI-e/a-ann＜1.0 at all the 6 sites at the same time, with mean MV-E/A ratio being 0.71±0.16 and mean E/e-ann ratio 15.91±6.78; groupⅡ(n=38): MV-E/A＜1.0, DTI-e/a-ann≥1.0 at 1-6 sites among the total sites, with mean MV-E/A ratio being 0.76±0.12 and mean E/e-ann ratio 10.37±2.63; group Ⅲ(n=23): MV-E/A≥1.0, DTI-e/a-ann≥1.0 at all the 6 sites at the same time, with mean MV-E/A ratio being 1.74±0.42 and mean E/e-ann ratio 9.57±2.39; group Ⅳ(n=53): MV-E/A≥1.0, DTI-e/a-ann＜1.0 at 1-6 sites among the total sites, with mean MV-E/A ratio being 1.31±0.31 and mean E/e-ann ratio 13.27±9.46. The mean ages of group Ⅰ, Ⅱand Ⅳ were older than that of group Ⅲ. Although there was no obvious difference between group Ⅰand groupⅡ in the mean age and mean MV-E/A (P＞0.05), the mean E/e-ann was much higher in group Ⅰthan that in groupⅡ (P＜0.05). The mean MV-E/A was similar in group Ⅲ and group Ⅳ (P＞0.05), but the mean age and mean E/e-ann in the latter were older and higher than those in the former (P＜0.05), respectively. The mean age in group Ⅳ was younger than that in group Ⅰand Ⅱ, while the mean E/e-ann in group Ⅳ was higher than that in group Ⅱ, but lower than group Ⅰ (P＜0.05). Conclusion ①Ratio of MV-E/A ＜1.0 and ratios of DTI-e/a-ann ＜1.0 at all the 6 sites indicates increasing LV filling pressures; ②MV-E/A≥1.0 and DTI-e/a-ann＜1.0 at 1-6 sites among the total sites predicts a tendency of high LV filling pressures; ③Wide variability may present in those with MV-E/A＜1.0, DTI-e/a-ann≥1.0 at 1-6 sites among the total 6 sites or MV-E/A≥1.0, DTI-e/a-ann≥1.0 at all the 6 sites at the same time; ④Age of the patient has great influence on the measurement of MV-E/A ratio and DTI-e/a-ann ratio.
