To observe the curative effect and the hemodynamic change of cervical vertigo treated by acupuncture, 66 patients were randomly divided into two groups: group A in which acupoints Yuzhen (BL 9) and Fengchi (GB 20) were used and Group B in which Cervical Jiaji points (C4-6) were used. Before and after treatment, the symptom of the cervical vertigo and the grade variety of function and the change of Color Doppler Flow Imaging (CDFI) of vertebral artery were observed. After treatment, the grade in two groups increased, there was a remarkable difference between two groups(P ＜ 0.05); after treatment, the grade of vertigo degree increased, there was a remarkable difference between two groups(P ＜ 0.05); needling Yuzhen (BL 9) and Fengchi (GB 20) can remarkably improve the symptom of cervical vertigo and vertebral artery blood flow rate, and the curative effect was superior to needling Jiaji points.

[Objective]To investigate the effect of salvianoli acid B and hyperoxic solution on experimental ischemia reperfusion injury of extremities.[Method]Twenty-four healthy New Zealand rabbits were divided into 4 groups randomly.Equivalent 0.9%Nacl(group A),hyperoxic solution(group B),salvianoli acid B(group C),salvianoli acid B and hyperoxic solution(group D) were injected through ear edge vein before ischemia.The femoral artery and vein were blocked and the model of ischemia reperfusion injury of extremities was set up.Before ischemia and after 4 hour's reperfusion,the blood samples were taken to measure the levels of blood malondialdehyde(MDA) and superoxide dismutase(SOD).The gastrocnemius muscles were observed by pathologic test.[Result]Serum enzymatic activity of MDA improved obviously.Salvianoli acid B and hyperoxic solution could prevent the improvement of it(P

Objective: The purpose of this research is to investigate the relationship between computer game addiction,a subtype of internet addiction,and parental Rearing styles.Methods: Using Computer Game Addiction Inventory(CGAI) and EMBU,we investigate a sample of 747 senior high school students in Beijing.According to whether participants' sum score of five dimensions of CGAI is larger than 1.5 SD,we divide them into two groups: tendency to addiction and non-tendency to addiction.Then we analyze the data with methods of MANOVA and Canonical Correlation.Results: There is significant difference in sex distributing between tendency to addiction and non-tendency to addiction.There is also significant difference in parental rearing styles between two groups.Under authoritarian rearing styles,children score higher on nearly every dimension of CGAI.Conclusion: Boys are more likely to get addicted to computer games than girls.Negative parental rearing styles associate closely with computer game addiction.

Objective To explore the diagnostic value of bronchofiberscopic washing cytology (BWC) and bronchoalveolar lavage fluid (BALF) ThinPrep cytology test (TCT) in the diagnosis of lung cancer.Methods Three hundred and eighty-five lung cancer patients who completed the BWC and BALF TCT were selected.The sensitivity was compared between the conventional smear and the two TCT methods.The sensitivity and accuracy of BWC and BALF TCT in the diagnosis of lung cancer were analyzed.Results The sensitivity of TCT was 76.1％ (293/385) in the diagnosis of lung cancer,and conventional smear was 54.8％ (211/385).The sensitivity of TCT was significantly higher than that of conventional smear (P ＜ 0.05).In the diagnosis of central lung cancer,the sensitivity of BWC TCT and BALF TCT was 74.4％ (131/176) and 70.5％ (124/176),and there was no statistical difference (P ＞ 0.05).In the diagnosis of peripheral lung cancer,the sensitivity of BALF TCT and BWC TCT was 83.3％ (174/209) and 44.0％ (92/209),and there was statistical difference (P ＜ 0.05).In BWC TCT,the accuracy of TCT and histology in squamous cancer was 92.7％ (127/137),in adenocarcinoma was 92.6％ (151/163),in small cell cancer was 96.8％ (61/63),and total accuracy was 91.9％ (354/385).In BALF TCT,the accuracy of TCT and histology in squamous cancer was 92.0％ (126/137),in adenocarcinoma was 94.5％ (154/163),and in small cancer was 98.4％ (62/63),and total accuracy was 92.7％ (357/385).Conclusions TCT has more diagnostic value in lung cancer.BWC and BALF TCT show different sensitivity in the diagnosis of lung cancer of different kinds.BWC TCT combination with BALF TCT is helpful to improve the diagnosis of lung cancer.

OBJECTIVE: To study the mechanism of herbal application along meridians for treatment and prevention of asthma by using serum pharmacological test to observe the effects of serum containing herbs against the constriction of tracheal spiral strips induced by acetylcholine chloride (Ach). METHODS: Guinea pigs were randomly divided into normal control group, normal saline (NS) application group, aminophylline application group, aminophylline injection group, 1-day herb application group, 7-day herb application group and 14-day herb application group. Asthma was induced by Hutson's method in guinea pigs except the normal control group. Guinea pigs in herb application groups were treated by external application of a compound herbal medicine 60 min once every day. Guinea pigs in NS application group were treated by external application of NS. Guinea pigs in the two aminophylline-treated groups were treated by external application and intraperitoneal injection of aminophylline at a dose of 400 mg/kg, respectively. The guinea pigs were killed and the sera were obtained after 1-day, 7-day and 14-day treatment in the three herb application groups, 7-day treatment in the NS application group, the aminophylline application and injection groups, respectively. Serum pharmacological method was used to do the experiment, the effects of different sera on the constriction of tracheal strips were observed, and the constriction rates were calculated. RESULT: The serum containing herbs had an effect in reducing the constriction of tracheal spiral strips induced by Ach, and the effect was similar to that of the serum obtained from the aminophylline injection group. The constriction rate of the tracheal spiral strips was decreased when herbal application treatment was prolonged within a period of time, and it became stable when herbal application treatment was between 7-14 days. The constriction of tracheal spiral strips induced by Ach could be reduced remarkably when it was previously treated by serum containing herbs. CONCLUSION: The anti-acetylcholine function with a time-dependent effect is one of the mechanisms of herbal application treatment along meridians for asthma, and furthermore, herbal application treatment along meridians might be useful for preventing asthma.

Aim To observe the effects of GCIP-27(G protein competitive inhibitory polypeptide-27) on the structure of left ventricle in spontaneously hypertensive rats(SHR).Methods Thirty SHR rats of 12 weeks old were randomly divided into five groups(n=6):blank control groups,GCIP-27(10,30,90 ?g?kg-1,ip,bid)groups,and Losartan group(6 mg?kg-1),six Wistar-Kyotos(WKY) rats were as normal control.Systolic blood pressure(SBP)was measured once per two weeks with tail-sleeve methods.At the end of the 8th week,left ventricle weight index(LVWI)were determined.Myocardium structure was observed by polaroscope and transmission electron microscope.The area and content of myocardial interstitial collagen were treated for semiquantitative analysis by image analyzer system.Results The SBP in GCIP-27(10,30,90 ?g?kg-1)groups decreased significantly from the 2 nd to the 8th week by comparison with blank control group.GCIP-27(10,30,90 ?g?kg-1) lowered heart mass index(HMI)and left ventricular mass index(LVMI)markedly compared with blank control group(P

Objective To investigate the effects of exercise therapy and health education on the hospitalization and exercise endurance of patients with moderate or severe chronic obstructive pulmonary disease (COPD).Methods A total of 86 patients with moderate or severe but stable COPD were divided randomly into an observation group (n=46) and a control group (n=40).The patients in both groups accepted general respiratory medical therapy.The patients in the observation group also accepted additional pulmonary rehabilitation therapy which consisted of exercise and health education while the patients in the control group only accepted health education and rehabilitation training guidance by telephone instead of standardized pulmonary rehabilitation therapy.The average recurrence of hospitalization,length of stay,and total bed time of all of the patients was tracked for a year before and after enrolment.Their 6 minute walking distance (6MWD) and quality of life (QOL) as reflected by using a scale recommended by the Chinese Society of Respiratory Disease before and after entering the study were evaluated.Results There was no significant difference between the groups in the year before entering the study in terms of their average frequency of hospitalization,length of stay or total bed time.In the year after enrollment average frequency of recurrence requiring hospitalization,length of stay and total bed time in the observation group all decreased significantly compared with the previous year,and all were significantly lower than in the control group.There were no significant differences between the groups in average 6MWD or average QOL score at entry,but in the subsequent year both groups' results improved significantly.Conclusion Long term pulmonary rehabilitation can not only enhance exercise endurance,it also improves QOL and relieves the economic burden of COPD patients on society.

Objective:To explore the structure of maternal verbal scaffolding features and develop a questionnaire on Mother's language scaffolding characteristics, so as to provide a quantitative, convenient and economical self-assessment tool for describing maternal verbal scaffolding features.Methods:On the basis of qualitative research and literature research, a questionnaire survey was conducted among 704 mothers of preschool children. After item analysis and exploratory factor analysis, a formal questionnaire was formed. Two weeks later, 106 mothers were retested to collect test-retest reliability data. Preschool children's expressive vocabulary checklist was used as external criterion.Data were analyzed by SPSS 18.0 and Amos 21.0.Results:(1)The formal questionnaire includes 28 items with two factors-detailed support factor and control rejection factor, the internal consistency coefficients of the two factors were 0.849 and 0.811, the project load was from 0 .482 to 0 .701, and the variance contribution rate was 40.36%.(2) AMOS 21.0 was used for confirmatory factor analysis, indicating that the two-factor structure met the requirements of psychometrics.( χ 2/ df=1.96, RMSEA=0.05, NFI=0.86, CFI=0.90, IFI=0.89). (3)The results of two-factor text-retest reliability were 0.840 and 0.871 as well as the results of split-half reliability was 0.801.The internal consistency reliability was 0.740.The external validity analysis showed that the mother's education level was positively correlated with factor Ⅰ( r=0.288, P=0.000), but not with factor Ⅱ( r=-0.091, P=0.052). There was significant difference in factorⅠbetween mothers with expressive vocabulary development delay children (52.22±10.56) and non delayed children (57.71±7.51) ( t=-5.07, P=0.000). There also was a significant difference in factor Ⅱ between mothers with expressive vocabulary development delay children (37.12±10.09) and non delayed children (31.53±8.59) ( t=4.61, P=0.000). (4)There was no significant difference in the characteristics of language scaffolding between boys(factorⅠ(58.08±8.14), factorⅡ(32.86±9.51)) and girls' mothers(factorⅠ(56.93±8.20), factorⅡ(31.42±8.48)). Analysis of the sample groups showed that age did not affect the verbal scaffolding features of preschool children's mothers( F1=1.633, P1=0.181; F2=0.758, P2=0.518). Conclusion:There are two factors in the questionnaire of the verbal scaffolding features questionnaire, which meet the criteria of psychometrics.The questionnaire of the verbal scaffolding features questionnaire is suitable for evaluating the characteristics of language scaffolding of mothers of preschool children aged 3-6.
