Objective To observe the effect of connect meridians inducing Yin from Yang on muscle-tension after cerebral infarction. Methods 82 patients with cerebral infarction in Second Hospital of Harbin from 2010 to 2014 were divided into observation group (n=41) and control group (n=41) according to hospitalization order. The observation group accepted acupuncture of connecting meridians inducing Yin from Yang, and the control group accepted the traditional acupuncture method for 2 weeks. The situation of spasticity, the motor limb function of limbs, and activities of daily living were evaluated with modified Ashworth Scale (MAS), Clinic Spasticity Index (CSI), Fugl-Meyer Assessment (FMA) and Barthel index (BI), respectively. Results Compared with the control group, the score of MAS decreased (t=2.212, P=0.030), the score of CSI decreased (t=2.514, P=0.014), the score of FMA increased (t=4.288, P<0.001), and the score of BI in-creased (t=2.970, P=0.004) in the observation group after treatment. Conclusion The acupuncture of connecting meridians inducing Yin from Yang can reduce the muscle-tension of limbs, improve the motor function and increase the activities of daily living.

OBJECTIVE To study the prevalence,fungal species,therapy and prevention of invasive fungal infections in our Affiliated Hospital.METHODS From Jan 2004 to Dec 2005,all patients with positive results for fungal culture of blood and sterile fluid were reviewed retrospectively.The in vitro activity of antifungal agents against fungal isolates was determined.RESULTS Eighty-eight positive patients were collected in this analysis based on the diagnosis of invasive fungal infection in our hospital for two years,from them the majority were diagnosed as candidal infections(n=72,81.8%),the others were Cryptococcus neoformans(n=8,9.1%),Aspergillus(n=5,5.7%) and other different fungal infections.The most common was C.albicans(n=48,66.7%),C.glabrata(n=12,16.7%),and C.tropicalis(n=8,11.1%),C.parapsilosis and C.krusei were both the same results(n=2,2.8%).CONCLUSIONS Infections caused by Candida are the most common invasive fungal ones in our hospital,and C.albicans is the most common one.Fluconazole remains effective for treament of candidal infections,especially those caused by C.albicans.

Objective:To investigate the effects of the β-casomorphin-7 on in vitro and in vivo mice splenic lymphocyte and macrophage nitric oxide production.Methods:Splenocytes proliferation assay and nitrite determination were employed for the studies of effects of β-casomorphin-7 on mice splenic lymphocyte and macrophage following in vitro stimulation of β-casomorphin-7 and in vivo intrapetitoneal administration and drinking β-casomorphin-7 solution administration.Results:In vitro study, β-casomorphin-7 showed a stimulation as well as a suppression of lymphocyte proliferation and significantly(P＜0.01) suppressed the production of nitric oxide. In vivo study, β-casomorphin-7 actions on lymphocytes and macrophages were accordant in intraperitoneal administration and drinking β-casomorphin-7 solution administration. β-casomorphin-7 significantly(P＜0.01) increased in splenic lymphocyte proliferative response and suppressed nitric oxide production in peritoneal macrophages.Conclusion:The present study indicates that the β-casomorphin-7 has the immunomodulatory effects and β-casomorphin-7 may be permeable into peripheral blood intact in mice of 2-3 weeks of age.

Objective To evaluate effects of daily average temperature on the occurrence of urticaria in Lanzhou city,and to analyze differences in the effects between different populations.Methods Time-series data on daily outpatient visits for urticaria between January 1,2007 and December 31,2013 were collected from the First Hospital of Lanzhou University and Lanzhou University Second Hospital.Daily meteorological data during this peroid were obtained from the Gansu Meteorological Bureau.Distributed lag non-linear models were used to analyze the association between daily average temperature and occurrence of urticaria,and the analysis was stratified by age and gender.Results The association between daily average temperature and daily number of outpatient visits for urticaria was nonlinear.Low temperature had significant lag effects on the daily number of outpatient visits for urticaria,with the maximum relative risk (RR) value (1.014 [95％ CI 1.000-1.023]) observed at 6 ℃ on lag day 18.Stratification analysis demonstrated that the effects of high temperature on the number of outpatient visits for urticaria were apparent on the day of exposure in age groups of 0-18 and 19-64 years,but decreased on the day of exposure in the age group ≥ 65 years.The effects of low temperature,which showed similar trends along with the increment of lag days in all groups,were relatively delayed and occurred 2 to 4 days after exposure.Conclusions Air temperature affects the occurrence of urticaria in Lanzhou city.Low temperature has evident lag effects on the occurrence of urticaria,while high temperature does not have.

Objective To evaluate effects of the daily average temperature on the daily number of outpatient visits for eczema in Lanzhou city.Methods Clinical data were obtained from outpatients with eczema in the Department of Dermatology of 2 third-grade class-A hospitals in Lanzhou city from January 1st 2007 to December 31st 2015,and meteorological data during this period were also collected.Controlling for confounding factors like long-term trends and day of the week,a distributed lag non-linear model (DLNM) fitted with quasi-Poisson link function was used to assess the effects of daily average temperature on the daily number of outpatient visits for eczema,and the analysis was stratified by season,age and gender.Results The exposure-response relationship between the daily average temperature and daily number of outpatient visits for eczema could be roughly described by a W-shaped curve.Stratification analysis showed that the effect of the daily average temperature on outpatient visits for eczema was strongest in autumn and winter,followed by summer,and weakest in spring.Low temperature may have lagged,cumulative and persistent effects on the daily number of outpatient visits for eczema,with the maximum relative risk (RR) value (1.12 [95％ CI:1.03-1.22]) observed at-9 ℃ on lag day 14.With a 1 ℃decrease in the temperature,16％ (RR =1.16,95％ CI:1.00-1.03),14％ (RR =1.14,95％ CI:1.02-1.26) and 13％ (RR =1.13,95％ CI:1.02-1.25) increases in the daily number of outpatient visits for eczema were observed in men,teenagers and middle-aged adults respectively (P ＜ 0.05).However,low temperature had no significant effects on outpatient visits for eczema among women or the elderly (P ＞0.05).The effect of high temperature usually occurred following exposure without lag periods,and was gradually weakened over lag time (P ＞ 0.05).Conclusions In Lanzhou,the effect of daily average temperature on outpatient visits for eczema was strongest in autumn and winter.Changes of the daily temperature may be one of risk factors for eczema.Low temperature had lagged effects on the daily number of outpatient visits for eczema,and the effects were strongest on lag day 14.

OBJECTIVETo study the significance of Fas and Fas-L expression in adenocarcinoma of uterine cervix.

METHODSBoth carcinoma tissue and their surrounding tissues from 36 patients with adenocarcinoma of uterine cervix, previously untreated either by radiation or chemotherapy, were studied for the expression of Fas and Fas-L by immunohistochemical stain with DNA apoptosis fragment detected by TUNEL.

RESULTSThe TUNEL labeling index was negatively correlated with differentiation of adenocarcinoma of cervix. Compared to highly differentiated and moderately differentiated tumor, the TUNEL labeling index was reduced obviously in poorly differentiated adenocarcinoma (P < 0.01). Fas expression was detected in 31 cases (86%) while there were only 3 weakly stained in the normal endocervical glands around the carcinoma. The 5 unstained carcinomas were 3 highly differentiated and 2 moderately differentiated. The positively stained Fas was associated with differentiation; the stronger the stain, the less differentiation there was. The Fas-L expression was detected in all adenocarcinomas while there was only 1 weakly stained in the normal ones. No significant difference was found in the expression of Fas-L in carcinomas with different degrees of differentiation. No correlation was observed between Fas and Fas-L expression.

CONCLUSIONSThe Fas expression is positively correlated with the different degrees of differentiation and Fas-L expression may be associated with the escape from of immunal surveillance.

Objective:To explore the professional care need of the disabled aged post stroke in 5 general hospitals in Shanghai so as to provide a basis for developing the home care service, formulating and implementing the scientific and practicable policy of home care service in Shanghai.Methods:From May 2019 to October 2019, this study selected 301 disabled elderly patients post stroke planning to level hospital and return home in Neurology Department from 5 general hospitals in Shanghai as subjects by convenience sampling. All of patients were investigated with the General Information Scale and the Professional Care Demand Tool for Stroke Survivors Lived in Community. The t-test, one-way ANOVA and multiple linear regression were used to analyze the influencing factors of care needs. Results:The total average score of the professional care need for the disabled aged post stroke was (3.46±0.83) . The top 5 items of care need included the disease recurrence prevention knowledge, getting the care and help from family members, blood pressure monitoring, use methods, attention and adverse reactions of common drugs, explaining disease related knowledge. There were statistical differences in the scores of professional care need among the professional care need of the disabled aged post stroke with different genders, family caregivers, disease types, duration of stroke, other chronic disease and degree of disability ( P<0.05) . The demand of patients who were female, took nursing workers or nannies as caregivers, were with cerebral hemorrhage, stroke duration>1 to 6 months, combined with diabetes and severe disability for professional care need was urgent. Multiple linear regression analysis showed that the influencing factors of professional care need of the disabled aged post stroke were genders (β'=0.117, t=2.327, P=0.021) and degrees of disability (β'=0.496, t=9.706, P<0.001) . Conclusions:The disabled aged post stroke in Shanghai has the high level of the professional care need. Related departments should accelerate the perfection and implementation of home care policy, and provide targeted nursing service based on the most urgent needs.

Objective:To compare the influence of dronedarone and amiodarone on the bleeding risk of patients with atrial fibrillation treated with rivaroxaban anticoagulation.Methods:Clinical data of 81 patients with atrial fibrillation treated with rivaroxaban anticoagulation at Xi'an International Medical Center Hospital from January 2020 to July 2023, including 36 patients treated with dronedarone and 45 patients treated with amiodarone, were retrospectively analyzed. The effects of dronedarone and amiodarone on the anticoagulation of rivaroxaban were compared using the incidence of bleeding events, thrombosis events, and adverse reactions as outcome measures.Results:The total bleeding in the dronedarone group [22.22% (8/36)] was significantly higher than that in the amiodarone group [6.67% (3/45)] ( χ2 = 4.12, P < 0.05). The total bleeding of conventional-dose rivaroxaban in the dronedarone group was 30.00% (6/20), while the total bleeding of low-dose rivaroxaban was 12.50% (2/16), with no statistical significance ( χ2 = 1.58, P > 0.05). No thrombotic events or adverse reactions to dronedarone or amiodarone were observed in all patients. Conclusion:Compared with amiodarone, dronedarone significantly increases the bleeding risk of rivaroxaban anticoagulation in patients with non-valvular atrial fibrillation, and reducing the dose of rivaroxaban in patients using dronedarone does not reduce the bleeding risk.

Objective To establish a rapid and sensitive liquid chromatography-tandem mass spectrometry(LC-MS/MS)analysis method for determination of unsymmetrical dimethylhydrazine(UDMH)contents in rat plasma and investigate the toxicokinetic characteristics of UDMH in rats.Methods Twenty-two SD rats were divided into the intravenous injection of 10 mg/kg dose group(4 females)and intragastric administration groups(low,medium and high dose,with 6 rats in each group,half males and half females).The rats were given 10mg/kg by intravenous administration and 10 mg/kg,30 mg/kg,and 90 mg/kg single dose of UDMH by gavage.Blood samples were collected from the orbital venous plexus at 0 hour before administration and at different time points after administration.The plasma samples were extracted with protein precipitation and derivatization before being analyzed using the LC-MS/MS method.Separation was carried out on a ZORBAX column(4.6mm×75mm,3.5 μm),with a mobile phase composed of 0.3％acetonitrile/formic acid at a flow rate of 1 mL/min.Propranolol was used as the internal standard.An electrospray ionization(Turbo Ionspray)source was applied and the mass spectrometer was operated in a positive MRM mode.Quantitative analysis showed that the ionization source unsymmetrical dimethylhydrazine and propranolol was at m/z:192.0→148.1,m/z:260.2→116.1,respectively.The toxicokinetic parameters were analyzed with the DAS 2.1 software.Results Quantification of UDMH exhibited a good linearity within the concentration range of 50-50000 ng/mL,with a linear correlation coefficient greater than 0.9900 and a lower limit of quantification of 50 ng/mL.The average recovery rate of UDMH was 98.1％,compared with 100.5％for the internal standard propranolol hydrochloride.The inter batch precision of standard curve samples ranged from 0.7％to 6.3％,and the relative error was between-7.1％and 6.2％.The inter batch and intra batch precision of quality control samples ranged from1.8％to 19.8％,and the relative error from-9.8％to 0.2％.The main pharmacokinetic parameters of UDMH in rats exposed to 10 mg/kg,30 mg/kg,and 90 mg/kg gavage were UC(0-t):(7624.99±2569.31),(34284.04±6657.15),(84720.88±22354.80)μg/L·h,t1/2:(0.07±0.15),(2.24±1.45),(3.04±0.90)h,Tmax:(0.75±0.27),(0.51±0.29),(0.29±0.10)h,Cmax:(4454.14±1329.45),(19442.45±9121.07),(32334.35±9882.41)μg/L,F:(77.34±26.06)％,(115.92±22.51)％,(95.48±25.19)％.Conclusion The LC-MS/MS method is highly accurate and specific,and is suitable for the toxicokinetic study of UDMH in rats.Single gavage administration of UDMH results in absorption and elimination saturation at a high dose.This study provides data for toxicological studies related to UDMH.
