ObjectiveAnalyze the mechanism of traditional Chinese medicine Salvia miltiorrhiza in treating coronary heart disease (CHD).MethodsThe animal experiment using actual research, namely the selection of rat isolated heart perfusion model, rat model of myocardial ischemia and ventricular tachycardia in rabbits model, then the effects of different animal groups in hemodynamics, coronary flow, serum superoxide dismutase (SOD) content, malondialdehyde (MDA) the results of the content.ResultsAfter treatment, the content of SOD was significantly increased and the content of MDA was significantly decreased in the treatment group, and the difference between the two groups was statistically significant (P<0.05).ConclusionTraditional chinese medicine Salvia miltiorrhiza has significant effect on the treatment of coronary heart disease, which is beneficial to the recovery of patients' condition, and is worthy of clinical application.

Objective To evaluate the expressions of MMP-7, E-cadherin in gastric carcinoma, and their relationship with tumor cell invasion and metastasis. Methods The MMP-7 mRNA and E-CD mRNA were detected by hybridization in situ in 78 gastric cancer tissues. Then analyze the relationship between the expression of MMP-7, E-CD and clinicopathological features. Results The expressions of MMP-7 and Ecadherin were significantly related with the invasion and metastasis of gastric cancer cell. The E-CD mRNA expression rate in MMP-7 mRNA positive gastric carcinoma tissue was much lower than that in negative carcinoma tissue (9.09 % vs 66.70 %). Conclusion Expression of MMP-7 mRNA and E-CD mRNA is associated with invasion, metastasis. Detection of MMP-7 mRNA and E-CD mRNA in bioptic specimens may be helpful in predicting tumor metastatic and recurrent potential and prognosis for patients with gastric carcinoma.

ObjectiveTo develop school refusal reason inventory (SRRI)for children and adolescents in China and assess its reliability and validity.MethodsThe primary SSRI was made based on clinical interviews and literatures.Pretest was carried out in a small sample from a clinic.Then the final SSRI was developed after qualitative analysis and item analysis.SRRI,the Screen for Child Anxiety Related Emotional Disorders(SCARED) and Child Depression Inventory(CDI) were administered to school refusers from 7 schools in Shenyang.All the schools were selected from Shenyang City and its countryside by cluster sampling.Some of the students were retested after one month.Descriptive statistics and exploratory factor analysis were carried out to examine the reliability and validity of SRRI based on all the data.Results Item analysis indicated correlation coefficients between all the items and the total marks were higher than 0.3,and they were significant.All the critical ratios of the items were higher than 0.3.The 43 items were divided into six factors ( educational modality,factor of teachers,relationship with classmates,separated anxiety,study attitude and study environment) by exploratory factor analysis.The factor loading values were 0.372 ~0.848.The cronbach's α of each factor was 0.827,0.831,0.759,0.623,0.821 and 0.808.Retest reliability was 0.644 (P < 0.01 ).Its correlation coefficient with SCARED was 0.452 and 0.548 with CDI.ConclusionAccording to Chinese cultural back ground,the SSRI corresponds with psychometric indexes.There are good reliability and validity.It is helpful to understand the reasons of school refusal behavior in children and adolescents.

Objective To investigate the correlation between the measurement methods of carotidcerebral pulse wave velocity (ccPWV) and the traditional method of brachial-ankle pulse wave velocity (baPWV).Methods A total of 136 healthy volunteers were divided into a youth group (20-39 years),a middleaged group (40-59 years),and an elderly group (more than 60 years) according to their ages.While detecting baPWV,transcranial Doppler ultrasound was used to simultaneously monitor the ipsilateral common carotid artery and the terminal segment of internal carotid artery.The time differences of the beating points of their cardiac cycles and the distanceses of the skin surfaces between the 2 probes were measured and ccPWV was calculated.Results The systolic blood pressure,pulse pressure and mean arterial pressure in the elderly group were signifificantly higher than those in the middle-aged group and the young group.The ccPWVs in the youth,middle-aged and elderly groups were 418 ± 52 cm/s,489 ±54 cm/s,and 599 ± 58 cm/s,respectively.The elderly group was significantly faster than the middle-aged group (t =7.308,P <0.001),and the middle-aged group was significantly faster than the youth group (t=6.758,P<0.001).A Pearson correlation analysis showed that ccPWV was significantly positively associated with the age (r=0.847,P<0.001) and baPWV (r =0.548,P <0.001).The multiple linear regression analysis showed that ccPWV was significantly positively associated with the age and diastolic blood pressure (partial correlation coefficients were 0.742 and 0.293respectively,P <0.001 and <0.010 respectively).Conchlusions ccPWV is a new measurement method for cerebrovascular stiffneas,and it has a good correlation with the traditional measurement method.
