OBJECTIVE To investigate the status of community health services and offer a scientific basis for making a direction of community to control the infective disease.METHODS Totally 1503 outpatients were investigated retrospectively for infective diseases in community.RESULTS The average age of these patients was 65,the number of females was much more than males.The most frequently infective diseases were upper respiratory tract infection,bronchitis,periodontitis,etc.CONCLUSIONS It′s necessary to strengthen the community health service and to establish an effective system of health service.The patients must cultivate a health habit of life,they not only need in time diagnosis and treatment,but also enhance own knowledge about health and disease prevention.

Objective:To investigate the comparison of diagnostic value between multi-slice spiral CT (MSCT) and MR pulmonary angiographies in the diagnosis of acute pulmonary embolism.Methods: 86 patients with acute pulmonary embolism who underwent imaging examination were randomly divided into control group (43 cases) and observation group (43 cases) according to random number table method. The patients in the control group were analyzed with MSCT for enhanced scan under pulmonary angiography. The patients in the observation group were analyzed with MR for pulmonary artery imaging and pulmonary embolism. These results were compared depended on above data.Results: The differences of sensitivity and Youden index between control group and observation group were statistically significant (x2=10.052,x2=10.052,P<0.05), and the sensitivity of observation group was higher than that of control group, and both the diagnostic specificity of the two groups were 100%. For embolism of different part, the accuracy of observation group was higher than that of control group. And for the comparison of left multiple between the two groups, the difference were significant (x2=4.168,P<0.05). While for the comparisons of single, bilateral and multiple for right side, the differences between the two groups were no significant (x2=2.355, x2=0.917,x2=2.912,P>0.05). For the diagnosis of various indirect symptom, the accuracy of observation group was higher than control group. For the comparison of diagnostic accuracy of pulmonary segments infarct between the two groups, the difference of them was significant (x2=5.630,P<0.05). While the comparisons of pericardial effusion, pleural effusion and pulmonary artery hypertension, the differences of them between the two groups were no significant (x2=3.214,x2=3.733,x2=3.281;P>0.05).Conclusion: For patients with acute pulmonary embolism, the diagnosis by using MR imaging technology has series advantages, such as convenient operation and higher diagnostic accuracy, and it can accurately determine the severe degree of the disease.

Objective To evaluate the detection capability for salt iodine test by using graphic method,and to provide reliable detection data for prevention of iodine deficiency disorders.Methods The examination results of external quality assessment for disease control mechanism in Liaoning Province in 2013 were analyzed by using standard Z score and Youden plot.The level of reproduction and type of error were analyzed by Z score sequence diagram in order to find the outliers and results need to be reviewed by the Youden plot.Salt iodine was detected by the general test method in salt industry for determination of iodine (GB/T 13025.7-2012).Results According to single sample evaluation of the Z score,111 laboratories were qualified,the qualified rate was 97.4％ (111/114).Three labs were not qualified,unqualified rate was 2.6％ (3/114).According to double sample evaluation of the Z score,112 laboratories were qualified,the qualified rate was 98.2％ (112/114).Two laboratories were not qualified,unqualified rate was 1.8％ (2/114).According to the Youden plot,5 laboratories were possible outliers with results need to be reviewed.Conclusion Statistical graphic method has displayed the examination results directly,which is helpful in searching targeted improvements,and improving the detection capability.

Methods Follow-up investigation on utilization and satisfaction of card-based health services and coverage of chronic illness management was conducted among cardholder living at Dongcheng District of Beijing during July 1,2006 and December 31,2008. Results The rates of attendance and health education increased from 47.20% or 1.16% to 90.90% and 46.38% ,respectively. The coverage of high blood pressure management and standard hypertension management increased from 47.16% or 45.66% to 80.39% and 78.27%, respectively. The satisfaction of cardholder residents with community healthcare services was improved year by year. Conclusions The health card service pattern plays a significant role in improving chronic disease management,which results in more satisfaction with and utilization of healthcare resources in community.

It is very difficult for stroke patients to complete the action of squatting-standing because their equilibrium function ability has been seriously declined. It was necessary, therefore, to do a deep research on the action of human squatting-standing and to set up an accurate model and simulation. In our modeling research, the movements of upper limbs and head was neglected, and a seven-segment model was developed to establish the coordinate system of human squatting-standing action. It calculated the knee joint moment and hip joint moment during squatting and standing by utilizing Lagrange method, and then simulated this mathematical model by utilizing Matlab. Geometric model of human squatting-standing was developed and simulated in ADAMS which proved that the established Lagrange model was reasonable. It would also provide significant theoretical references for further study and development of squatting-standing rehabilitation training equipment.

Objective:To study the possible therapeutic mechanisms of triptergium wilfordi in treating glomerulonephritis.Methods:Thirty seven patients with IgA nephropathy were detected urine mononeuclear cells densities with flow cytometry during taking triptergium wilfordi tablets,30 healthy people were used as normal control.Results:The patients urine CD3 +?CD4 +?CD8 +?CD14 + and CD44 + cells densities were much higher than normal control's,but obviously decreased after triptergium wilfordi treatment.CD4/CD8 ratio was much lower in patients than in normal control.It increased markedly after treatment.Patients who reached remission initially had a lower CD4 + cell percentage and higher CD14 + cells percentage than those showed no response to triptergium wilfordi treatment.Conclusion:Triptergium wilfordi could modulate kidney immune cell function and adhesive molecule CD44 expression.Its effects were associated with renal immunity.

Objective: To study the effect of low fat diet on expression of protein kinase B (PKB) in adipose tissue of rats with insulin resistance. Method: Thirty male Wistar rats were randomly divided into control group ( C, n=10),given low fat diet; model group (M, n=20), given high fat diet. After 4 w, group M was randomly divided into 2 subgroups accepting diet intervention of 6 w.(1)High fat group (HF) was continually given high fat diet;(2)Low fat group (LF) accepted low fat diet. The expression of PKB stimulated by insulin in adipose tissue was determined with Western blotting at the end of the experiment. Results: (1) Group M showed hyperglycemia, hyperinsulinism, hypertriglyceride, hypercholesterolemia and elevated HOMA insulin resistance index (HOMA-IR) while the insulin sensitivity index (ISI) was obviously reduced compared to group C, indicating that the insulin resistant model was induced ; (2) Low fat diet treatment decreased FBG,TG,TC,which were accompanied by lower HOMA-IR and elevated ISI; (3) Because of long term high fat diet, expression of PKB in adipose tissue of group HF decreased by 23.5% (P
