Investigation on current situation of Plasmodium microscopic examination capabilities of professional staff in medical situations in Wuxi City / 中国血吸虫病防治杂志

Objective To investigate the capabilities of Plasmodium microscopic examinations of professional staff in medi-cal institutions in Wuxi City,so as to provide evidences for improving malaria control and elimination work in the future. Meth-ods The data of questionnaires for laboratorial staff in charge of Plasmodium microscopic examinations were collected and ana-lyzed in the medical institutions in Wuxi City in 2016,and the influencing factors related to the capabilities of Plasmodium mi-croscopic examinations were analyzed by the method of logistic regression. Results Totally 54 laboratorial workers in 54 medi-cal institutions in Wuxi City were investigated,16 of them were male,and 38 were female,and the ratio of male to female was 0.42:1. Among the 54 laboratorial workers,12 persons(22.22％)had the experience of detecting Plasmodium in the work. The multivariable analysis showed the ability to detect Plasmodium was associated with male laboratorial workers(adjusted OR =0.11,95％CI:0.02-0.53),laboratorial workers with intermediate or higher professional titles(adjusted OR=5.31,95％CI:1.04-27.19)and laboratorial workers from county and township medical institutions(adjusted OR=0.04,95％CI:0.01-0.98). Conclusions All of the medical institutions in Wuxi City have the capability of microscopic examinations of Plasmodium. How-ever,the ability of laboratorial staff in primary hospitals still should be improved.

Evaluation on capability of parasitic disease control and prevention among professional and technical personnel in medical and health institutions in Wuxi City / 中国血吸虫病防治杂志

Objective To understand the capability of parasitic disease control and prevention among professional and tech?nical personnel in medical and health institutions in Wuxi City,so as to provide the evidence for promoting relative capability building. Methods Forty?one professional and technical persons from 22 medical and health institutions received the evalua?tion through the theoretical knowledge exam and laboratory operation skill assessment. Results The average score of theoretical knowledge exam was(76.5±15.6)with the pass rate of 80.5%and excellent rate of 48.9%. The average score,pass rate and ex?cellent rate for Plasmodium blood slide making were(7.3 ± 1.5),87.8%and 41.5%respectively,the average score,pass rate and excellent rate for Plasmodium blood slide reading were(14.0 ± 7.2),31.7% and 12.2% respectively;the average score, pass rate and excellent rate for helminthes microscope examination were(19.4 ± 10.4),24.4%and 0 respectively;the average score,pass rate and excellent rate for Oncomelania hupensis snail identification were(8.6±1.1),95.1%and 73.2%respectively. The average scores of helminthes microscope examination and Oncomelania hupensis snail identification were higher in the par?ticipants with middle?level professional title or above than in the participants with primary level professional title (both P <0.05). The average scores of theoretical knowledge exam,Plasmodium blood slide reading and helminthes microscope examina?tion were higher in the participants from disease control and prevention institutions than in the staff who came from medical insti?tutions(all P<0.05). Conclusions The professional and technical personnel in medical and health institutions in Wuxi do bet?ter in theoretical knowledge,Plasmodium blood slide making and Oncomelania hupensis snail identification. However,the capa?bility of parasite microscope examination is urgently needed to be improved in the future.

Analysis of epidemic situation of malaria in Wuxi City from 2005 to 2014 / 中国血吸虫病防治杂志

Objective To understand the epidemiological characteristics of malaria in Wuxi City,and explore effective strat?egies and measures for malaria elimination. Methods The data on malaria cases in Wuxi from 2005 to 2014 were collected and analyzed. Results In Wuxi City,from 2005 to 2014,201 malaria cases were reported,of which,there were 52 local cases and 149 imported cases. Totally 156 malaria cases were reported from 2005 to 2009,of which 6 cases were infected with Plasmodi?um falciparum,and 45 malaria cases were reported from 2010 to 2014,of which 23 cases were infected with P. falciparum. From 2005 to 2009,the ratio of male to female was 2.39:1. Migrant workers,farmers and workers were the major infected popu?lations,with a proportion of 41.03%,17.95% and 9.62%,respectively. From 2010 to 2014,the ratio of male to female was 10.25:1. Workers,farmers and migrant workers were the major infected populations,with a proportion of 37.78%,11.11%and 6.67%,respectively. The peak of malaria incidence was observed from May to October. From 2005 to 2009,most cases were re?ported by CDCs,and from 2010 to 2014,most cases were reported by medical institution. There was an increase in proportion of P. falciparum. Conclusion The control and prevention of malaria should focus on imported cases in the future in Wuxi. The doctors should improve the capacity of malaria diagnosis and treatment.

Determination of Organochlorine Pesticides Residue in Suppositories of Chinese Medicinal Materials(Ⅰ) / 中药新药与临床药理

Objective To develop a suitable extraction and purification method for detecting the residue of 20 kinds of organochlorine pesticides(OCPs) in suppositories of Chinese medicinal materials which are made of fat-soluble bases.Methods Different methods were applied for the extraction, and GPC was used for the purification of the sample Huazhi Shuan, and then the residue contents of OCPs were determined by GC- ECD method.20 kinds of OCPs were added to the samples and the feasibilities of the methods were evaluated by the obtained recovery. The established method were used in the analysis of the residue of OCPs in other Chinese herbal suppositories.Results The recovery and the reproducibility of this method met the requirements for the analysis of pesticides residues. Conclusion This developed method may provide reference for the detection of organochlorine pesticides residue in these kinds of Chinese medicinal preparations.

Methodological Study of Determining Organochlorine Pesticides Residue in Suppositories of Chinese Medicinal Materials(Ⅱ) / 中药新药与临床药理

Objective To develop a suitable solid-phase extraction(SPE)method for the further purification of the test solu- tion in suppositories of Chinese medicinal materials which are made of lipid soluble bases,and to detect the residues of 20 kinds of organochlorine pesticides(OCPs).Methods Different kinds of SPE columns were selected and several elution solvents were used for the purification of the sample of herbal medicine of Huazhi Shuan,and then the residue contents of OCPs were determined by GC-ECD method.Twenty kinds of OCPs were added into the samples and the efficacy of the methods were eval- uated by the obtained recoveries.Results The recoveries of the 20 kinds of OCPs being detected were basically comply with the requirements for the analysis of pestiside residues.Conclusion After the tested solution is obtained from GPC column and is further purified through florisil SPE column,the impurity can be removed and the high accuracy of the quantitative analysis of the compounds can be achieved.
