To observed the Clinical effect of ropivacaine (Rop) of different concentration used for analgesia of labor, and ex plore the ideal concentration and dosage. Methods: 45 case s of ASA Ⅰ-Ⅱ primiparae nearing labor were vandomly divided three groups rand omly (0.16% Rop group, 0.2% Rop group were assigned 15 cases). The analgesia, in which the cervical os had opened up to 2-3cm; the controlled group was not giv en the analgesia of labor. BP, SpO2, EKG, PETCO2, cerrical contraction , fetal cardiac sounds were monitored continuously in the perinatal analgesia pe riod. The analgesia effects were determined by giving a mark for pain by VAPS, motor nerve blockings were given amark by Bromage scale; Apgar scale were conduc ted 1-5 min after neonates were labored out. Results: The vital signs of three groups were stable in perinatal; the VAPS scale was lower s ignificantly in observed group than in controlled group; while the blocking freq uency and extent of motor nerve were highest from 0.2% Rop, which had light inhi bitory effect to cervical contraction, causing the dosage of oxytocin to increas e relatively; the NACS scale 24 h after labor was more increased significantly in observed group than controlled group. Conclusion: The un ique blockings to sense and motor were obviously separate, having no obvious eff ect to blood stream of uterus and placenta, being benificial to analgesia in per inatal. The 0.16% Rop was a more ideal local anaesthesia agent than 0.2% Rop .

Objective To investigate the surgery outcomes between patients with different recovery states measured by visual analog scores (VAS),explore the relationships among surgery outcomes,bone cement,and degrees of pain relief,and to find out the best combination of cement volume and cement distribution for Percutaneous kyphoplasty (PKP).Methods There were 220 patients with 220 vertebra,from January 2012 to January 2014,who received PKP in our hospital.Patients were divided into two groups,on the basis of different VAS.The epidemiological data,operative effect,and surgical complications were compared between two groups.Characteristic curve (ROC) was used to analyze the effect of bone cement dosage and distribution on the diagnosis of patients with different recovery state.The correlation was analyzed between the dose and distribution of bone cement and surgery outcomes.Moreover,logistic regression analysis was used to assess the safety of cement implantation.Results A total of 77 recuperators and 143 non-recuperators were included in the study.Two groups of patients in epidemiological data showed no significant difference.The surgery duration,bone cement injection dose,cement distribution,vertebral height restoration rate and improvement of kyphotic angle in the recuperator group were all significantly higher than those in the non-recuperator group.Whether small dose and large dose of bone cement volume and expanded the bone cement distribution area could significantly improve the patient of operation after the recovery rate and bone cement dose with extensive bone cement distribution area and large bone cement dose with limited bone cement distribution area had the same operation after the recovery effect (x2 =2.880,P =0.090).When the cement volume was constant,cement distribution was positively correlated with the restoration rate of vertebral height and improvement of the kyphotic angle (r2 =0.207,P ＜ 0.01;r2 =0.159,P =0.02).Conclusions The value of cement distribution is better than cement volume in relieving patient pain for diagnostic.For PKP,cement distribution above 0.49 with small cement should be suggested.

Objective: To investigate the effects of extract of Bulbus Allii Caespitosi on cardiocyte viability of swines with myocardial reperfusion injury by analyzing the 18F-fluorodeoxyglucose ((18)F-FDG) position emission tomography (PET) imaging. Methods: Twenty-four swines were randomly divided into sham-operated group, untreated group, trimethazine group and extract of Bulbus Allii Caespitosi group. Myocardial reperfusion injury was induced by plugging the anterior descending coronary artery of swine with sacculus. Bulbus Allii Caespitosi or trimetazidine was given twice daily for 28 days. Then myocardial perfusion was detected with (18)F-FDG PET/CT and the radioactivity distribution was evaluated. Results: Compared with the untreated group, Bulbus Allii Caespitosi and trimetazidine could improve the activity of myocardial cells after myocardial infarction (P<0.01), and there were no significant differences between Bulbus Allii Caespitosi and trimetazidine (P>0.05). Conclusion: Bulbus Allii Caespitosi can improve myocardial metabolism after ischemia and reperfusion in swines.

Objective To study the clinical features and spirometry of children with chronic cough and positive findings by bronchial provocation test.Methods Four hundred and fifty children with chronic cough from 3 hospitals of Shanghai Children's Medical Center Affiliated to Shanghai Jiao Tong Medical University School of Medicine,Gong Li Hospital of Pudong New Area,Pudong Hospital,were enrolled in this study from December 2012 to December 2014,and among them,373 cases completed the questionnaires,spirometry and bronchial provocation test.The differences in clinical features and spirometry between the bronchial provocation test positive group and negative group were compared.And the further evaluation of their clinical value was performed.Results Two hundred and thirty-six cases of children with bronchial provocation tests positive showed much higher rate of dry [72.03％ (170/236 cases)] and night cough[58.90％ (139/236 cases)] than those in the negative group[27.00％ (37/137 cases),22.63％ (31/137cases)],and the differences were significant (x2 =71.154,45.973,all P ＜0.01).Children in positive group also had higher morbidity of eczema[52.12％ (123/236 cases)],allergic conjunctivitis [24.15％ (57/236 cases)] and inhaled allergy history[40.25％ (95/236 cases)] than those in negative group[32.85％ (45/137 cases),10.95％ (15/137cases),18.98％ (26/137 cases)],and there existed significant differences (x2 =13.006,9.701,17.904,all P ＜0.01).And they also had higher asthma heredity [18.22％ (43/236 cases)] than that in negative group [9.49％(13/137 cases)],and the difference was significant (x2 =5.179,P =0.023);with worse small airway function [50.85％ (120/137 cases) vs 36.50％ (50/137 cases)] (x2 =7.197,P =0.007).For further study,the sensitivity and specificity for dry cough were both high(72.03％ and 72.99％).For specificity,family history was the most highest one (90.51％),and night cough and allergic conjunctivitis were also high.Conclusions Pulmonary function tests to reflect small airway function abnormalities,combined with a family history of asthma and chronic cough in children related to eczema,allergic conjunctivitis,and inhalation allergy history clinical features,can better predict airway hyperresponsiveness.

Objective To evaluate effectiveness of guideline-oriented training for community healthcare workers (HCWs) with The Applied Standards for Hypertension Prevention and Control at the Grassroots to provide guidance to hypertension management in communities. Methods In 2003, four community health-care service centers in Beijing were selected and assigned as intervention (one at urban and one at rural) and control (one at urban and one at rural ) groups, respectively. HCWs in the intervention group received guideline-oriented training based on The Applied Standards for Hypertension Prevention and Control at the Grassroots, while HCW in the control group did not. All HCWs participated in tests of the knowledge of hypertension management using the same questionnaire before and after the training to analyze their changes in awareness scores with a full of 32. Results There were 39 and 33 HCWs in the intervention group and 15 and 16 HCWs in the control group, respectively at urban, and 30 and 33 HCWs in the intervention group and 21 and 22 HCWs in the control group, respectively at rural before and after the training were involved in the tests, respectively. After training, overall knowledge scores of hypertension prevention and control in HCWs in the intervention group at urban increased obviously, with an average score of 26 of 32 ( 81.0% ) after training from 15 of 32 (45. 6% ) before it ( P ＜ 0. 01 ) , with a net increase of 28.5% (9/32), as compared to HCWs in the control group. Those at rural increased to 6. 6% (20/32) after training from 40. 7% (13/32) before it ( P ＜ 0.01 ), with a net increase of 22. 2 percent (7/32), as compared to HCWs in the control group. Their awareness of knowledge of hypertension prevention and control significantly improved, with the most obviously in the target of blood pressure control (51.7% vs. 31.5% ) and principles of pharmaceutical therapy (42. 2% vs. 27. 6% ). Conclusions Guideline-oriented training based on The Applied Standards for Hypertension Prevention and Control at the Grassroots can effectively improve community HCWs' awareness of knowledge of hypertension management and should be widely promoted in communities.

Objective To investigate the correlation between plasma soluble CD14 (sCD14)level and disease progression in patients with acute phase of acquired immunodeficiency syndrome (AIDS). Methods Forty-one human immunodeficiency virus (HIV)-infected patients were followed up from June 2007 to June 2010 in Beijing You′an Hospital,including 20 patients with CD4 + T lymphocyte counts more than 350/μL,and 21 less than 350/μL after 3 years of HIV infection.Twenty healthy blood donors were recruited as controls.Enzyme-linked immunosorbent assay (ELISA)was employed to test the plasma sCD14 level of healthy controls and patients infected with HIV at 1 -30 d,31 -90 d,91 - 180 d and 181 -360 d.Student t test was used to compare the means between two groups.ANOVA analysis was used to compare the means among more than two groups.Results The mean plasma sCD14 level in control group was (1 654±904)μg/L.Three years after HIV infection,the sCD14 level of patients with CD4 + T lymphocyte counts less than 350/μL group was (4 214±2 635)μg/L,which was higher than that of patients with CD4 + T lymphocyte counts more than 350/μL ([2 275 ±1 457 ]μg/L).The difference was statistically significant(t=-5 .41 ,P <0.01).The plasma sCD14 level in patients infected with HIV 181 -360 d was significantly higher than that in patients infected with HIV 1 - 30 days ([4 485 ± 2 779]μg/L vs [2 577 ±1 635 ]μg/L;t = -3.39,P <0.05 ).The plasma sCD14 level was positively correlated with HIV viral load (r =0.35,P =0.000 1 ),and negatively correlated with CD4 + T lymphocyte counts (r=-0.28,P =0.001 ).Conclusions The plasma sCD14 level in patients with acute phase of HIV infection is higher than that of healthy people,which increases with prolonged HIV infection.Plasma sCD14 level in of HIV infection acute phase may be closely related to HIV/AIDS progression.

ObjectiveTo investigate bronchial provocation test (BPT) and small airway function in children with cough variant asthma (CVA).MethodsA total of 353 children with chronic cough whose mean age was (7.45±2.58) years from three hospitals of Pudong district were enrolled during May 2012 and February 2014. Conventional pulmonary function tests, BPT and questionnaire survey were performed and the difference in pulmonary function was analyzed between children with positive BPT and negative BPT.ResultsIn 353 children with chronic cough, there were 200 children (56.66%) diagnosed as CVA with posi-tive BPT. Compared with BPT negative group, the percentages of nighttime cough and severe dry cough in BPT positive group were signiifcantly higher while the percentages of morning/daytime cough and wet cough were signiifcantly lower (P<0.01). Fur-thermore, the rates of history of atopic dermatitis and rhinitis in BPT positive group were signiifcantly higher than those in BPT negative group (P<0.01). Forced expiratory lfow at 75% relfecting the small airway function was signiifcantly lower in BPT posi-tive group than that in BPT negative group (P=0.032).ConclusionsBronchial hyperresponsiveness and decreased small airway function are the important pathological features of CVA. BPT and spirometry have clinical signiifcances in the CVA diagnosis and the analysis of cause of chronic cough.

Objective To evaluate white matter nerve fiber changes of children with binocular ametropic amblyopia by applying the technology of diffusion tensor imaging and the whole brain analysis method of deterministic tractography,and analyze its correlation with visual acuity.Methods Fourteen binocular ametropic amblyopia children was collected from the Second Xiangya Hospital of Central South University as study subject of experimental group,14 cases of normal sight children as the control group.All children were scanned by MRI system,conventional MRI examination,3DTlWI scan were made,then echo-planar sequence scanning was used to obtain diffusion tensor imaging.Quantitative analysis was made to all diffusion tensor imaging using deterministic tractography.Using the experimental group tracts with statistic changes of FA value,volume and tract count as the region of interest(ROI),the correlation analysis with vision for each ROI was performed.Results Isoametropic amblyopia children demonstrated low FA values in the right ventral and dorsal pathway,right optic radiation and corpus callosum compared to control group.There was low volume of fibers in the bilateral ventral and dorsal pathway,the left optic radiation and body of corpus callosum compared to control group.The tract count of right dorsal pathway had reduced compared to control group.Among FA value,tract count and volume,FA value had the maximum regression coefficient with visual acuity,the regression coefficient of tract count and volume was small.The relative correlation coefficient of FA value at right optic radiation,right ventral pathway and body of corpus callosum with vision acuity were 0.486,0.534 and 0.456,respectively,the right ventral pathway had the maximum correlation with visual acuity.Conclusion Isoametropic amblyopia patients shows abnormal structure on bilateral optic radiation,bilateral ventral and dorsal pathway and body of corpus cailosum,these may cause the capability loss of object recognition and spatial position recognition.The FA value of right ventral pathway has the maximum influence on visual acuity.
