RESULTS:The asthma symptom had been relieved significantly and then the patients were discharged from the hospital after clinical phar-macists disposed the symptom appropriately. CONCLUSIONS:The participation of clinical pharmacists in pharmaceutical care for pregnant patients with asthma in respiratory department. Can improve the prognosis effectively and guarantee the safety of drug use.

Subclinical hypothyroidism is a metabolic disease, defined by increased thyroid-stimulating hormone (TSH) and accompanied by normal thyroid hormone levels. Recent years, many domestic and foreign studies have showed that sub?clinical hypothyroidism may be related with atherosclerosis and left ventricular diastolic dysfunction, which increasing the risk and mortality of cardiovascular diseases. Subclinical hypothyroidism may be associated with lipid metabolic disorders, hypertension, coagulation dysfunction, endothelial dysfunction, abnormal glucose metabolism, homocysteine, C-reactive pro?tein and lipoprotein. At present, controversy persists on the subclinical hypothyroidism. The aim of this study is to review the correlation between cardiovascular diseases and subclinical hypothyroidism.

Objective To evaluate the effect of a new schistosomiasis control strategy based on the infection source control in four-lake regions of Hubei Province. Methods The new strategy based on the infection source control included the safe water sup-ply,feces harmless treatment,replacing cattle with machine,captive livestock,chemotherapy,Oncomelania hupensis snail con-trol in susceptible areas,hardening ditches,etc,and the new control strategy was implemented for 7 years in 9 counties(cities or districts)of the four-lake regions. The schistosomiasis situations were investigated before and after the intervention of the new strat-egy. Results The coverage rates of feces harmless toilets(three format toilets),biogas digesters,and safe water supply were 42.00%,23.16% and 93.76%,respectively. The number of ditch hardening was 1 960;the area of eliminating snails was 1 378.42 hm2;the number of persons who received the health education was 3 524 818 accounting for 92.17%of the total popula-tion;the number of person-time of taking active protection measures was 516 636 963. The average annual decline rates of schisto-some infection were 24.42%and 38.38%in residents and cattle,respectively. The endemic villages decreased by 4.77%,the vil-lages with snails decreased by 7.05%,and the villages with snails accounted between 63.19%and 66.21%of the total endemic vil-lages. The area with snails decreased by 90.35%,and the advance schistosomiasis patients decreased by 5.55%,and the fatality rate of advanced schistosomiasis patients decreased by 1.24%. No acute schistosomiasis patients occurred. Type One and Two en-demic(heavy endemic)villages decreased to zero;Type Three endemic(moderate endemic)villages decreased by 10.22%;but Type Four endemic(mild endemic)villages increased by 66.38%;and Type Five endemic(no endemic for 5 years)villages de-creased by 0.22%. The standards of schistosomiasis transmission controlled have achieved on schedule. Conclusion The imple-mentation of the new schistosomiasis control strategy based on the infection source control in four-lake regions of Hubei Province can effectively control schistosomiasis.

Myocardial infarction (MI) is a major cause of death and disability worldwide.The definition of myocardial infarction has been updated.Released in 2012,Third Universal Definition of Myocardial Infarction of ESC/ACCF/AHA/WHF Expert Consensus,made the clinical application value of troponin clear and suggested to monitor the dynamic changes of cTn in patients with suspected,emphasized the importance of clinical differential diagnosis.In consensus,it also noted that the application of high sensitive troponin can lead to false positives results,and pointeds out that in the assessment of cardiac injury associated with percutaneous or surgical coronary procedures,the rational cut-off value of cTn remains controversival.In addition to acute coronary syndrome,cTn elevations are common in many disease states,and with the improvement of detection sensitivity,low level increase of cTn,will be more.In acute and chronic heart failure,the cTn is elevated,and ACS may be the cause of worsening heart failure,So we should identify whether the cTn elevation is pure from the myocardial injury of heart failure or myocardial necrosis caused by ACS.Nowadays,the increased incidence of myocardial infarction has much to do with the wide application of cTn.Clinical applications of cardiac biomarkers and imaging techniques are flexible as the differences in the diagnostic techniques of myocardial infarction among countries and regions result.

Objective to compare the calculated effective radiation dose variations in cardiac interventional procedures of coronary angiography(CAG)and percutaneous transluminal coronary angioplasty (PCI)by using the different tissue weighting factors recommended by ICRP Publication 60 with that recommended by ICRP Publication 103.Methods Measurements of organ doses were carried out with an anthropomorphic phantom equipped with thermoluminecent dosimetry.The effective radiation doses were separately calculated using the tissue weighting factors provided by ICRP 60 and provided by ICRP 103,and the results obtained from ICRP 60 were compared with that obtained from ICRP 103.Conversion factors of effective radiation dose to dose area product(DAP)were also calculated according to different publication. Results The variations in the effective dose were 6.88%for CAG and 8.46%for PCI.The effective dose variations in CAG and PCI were 7.25%and 8.76%for female and were 6.51%and 8.17%for male, respectively.The effective conversion factors of DAP were 0.10～0.11 and 0.13～0.14 for CAG and PCI, respectively,according to ICRP 60 and 103.Conclusion The variation of conversion factors of effective dose indicates that in making estimation of effective radiation dose by using the widely accepted conversion factors,the adjustment of organ weighting factors recommended by ICRP 103 should be considered.

Objective To identify factors influencing behavioral changes among injection drug users(IDUs)by assessing the outcome of the Kunming Sunshine Homeland Project(SHP)in 2007,so as to design more effective and relevant interventions for HIV/AIDS prevention and control in China.Method Data obtained from SHP were analyzed by Logistic regression,in which the relationship between related factors and effectiveness of the interventions were examined.Results Based on Fishbein and Guinan’s hypothesis(1996),among the three factors,i.e.attitude,perceived behavioral norm and self-efficacy,the perceived behavioral norm was the most effective one to change IDUs’ behaviors.Conclusions In designing HIV/AIDS prevention and control projects targeted to IDUs,perceived behavioral norms should be given high priority in combination with other 2 factors,and the approaches applied should match with the objective of the designed project.
