Objective To understand the current state of staff for Plasmodium microscopy examinations in Changzhou City in the early stage of eliminating malaria action,so as to provide the evidence for achieving the target of malaria elimination. Methods The staff for Plasmodium microscopy examinations from medical institutions and centers for disease control and prevention at differ-ent levels were investigated by questionnaires and tests of the malaria related theory and microscopic operation. Results Totally 95 people were investigated,and among them,40.0%had college degree and 45.3%were university educated. There were 18.9%of them working on Plasmodium microscopy examinations for less than 1 year,40.0%for 2-5 years,18.9%for 6-10 years and 22.1%for more than 10 years. The numbers of person-time of provincial and municipal level training,district-level training,and unit-level training in the last year were 0.57,0.59,and 0.14,respectively. Totally 18.9%of them had the experience of finding Plasmodium at work,and 97.9% of them considered it was necessary or very necessary to do Plasmodium microscopy examina-tions. However,57.9%and 8.4%of them considered Plasmodium microscopy examinations increased their work load and work dif-ficulty,respectively. The average correct rates of knowledge tests on malaria before and after training were 72.5%and 91.6%re-spectively(P<0.05). The average mark of Plasmodium microscopic tests was 25.3 points(full mark being 50 points),and the passing rate(≥30 points)was 58.9%. Conclusion The working experience of staff for Plasmodium microscopy examinations in Changzhou City is relatively poor,and the related training should be enhanced.

OBJECTIVE:To investigate the effects of NOS1AP rs12742393 A/C gene polymorphism on lipid-regulating re-sponse of rosuvastatin calcium. METHODS:Two hundred and tuirty six patients with coronary heart disease(CHD)were selected from cardiology department of our hospital during Jan. 2014-Jun. 2015,and then given rosuvastatin calcium and other symptomatic treatment for 12 weeks. Polymorphism of NOS1AP rs12742393 A/C was detected by PCR-RFLP. The levels of TG,TC,HDL-C and LDL-C were detected by photoelectric colorimetry before treatment and 4,12 weeks after treatment. The serum relationship of genotype with the level of blood lipid was analyzed. RESULTS:Among 236 CHD patients,there were 131 cases of AA genotype (55.5%),98 cases of AC genotype(41.5%) and 7 cases of CC genotype(3.0%);genotype and allele frequencies met the Har-dy-Weinberg balance(P>0.05). There were 132 patients with normal blood lipid and 104 patients with hypercholesterolemia;there was statistical significance in genotype and allele frequencies (P<0.05). Among 104 CHD patients with hypercholesterolemia be-fore treatment,there was no statistical significance in the levels of TG,TC,LDL-C and HDL-C between AA genotype and AC+CC genotype(P>0.05). 4th and 12th week after treatment,the levels of TG,TC and LDL-C in different genotypes were all de-creased significantly;4th week after treatment,the level of LDL-C in AC+CC genotype was significantly lower than AA genotype, and the change compared to before treatment was significantly more than AA genotype,with statistical significance (P<0.05). There was no statistical significance in the level of HDL-C among different genotypes compared to before treatment;there was no statistical significance in the levels of TG,TC and HDL-C 4th,12th week after treatment and their changes compared to before treatment between AA genotype and AC+CC genotype;there was no statistical significance in the level of LDL-C 12th week after treatment and their changes between AA genotype and AC+CC genotype(P>0.05). CONCLUSIONS:NOS1AP rs12742393 A/C gene polymorphism is associated with CHD complicated with hypercholesterolemia;the C allele of NOS1AP rs12742393 may strengthen the response of CHD patients with hy-percholesterolemia to rosuvastatin calcium through influencing the level of LDL-C.
