Objective To analyze the assessment results and summary the work experience of malaria elimination in Baise City. Methods According to The malaria elimination evaluation schemes of Guangxi(2014 edition),the examination and evaluation of malaria elimination were carried out and all the results were analyzed in 12 counties(county?level city or district) of Baise City from 2014 to 2015. Results Since 2009,there were no local malaria cases and imported secondary cases in Baise City for the 6 consecutive years,and the detailed data were collected and the self?assessment reports of malaria elimination were written in all the counties. There was no omission or delay of malaria case reports in the 12 counties. The highest score of the ex?amination and evaluation was 96.58 points,the lowest was 90.76 points,and the average was 93.77 points. The biggest impact on the evaluation scores was“on?site examination”. Conclusion All the 12 counties(county?level city or district)of Baise City have passed the municipal examination and evaluation of malaria elimination,and the key of next work is malaria monitoring, timely finding and treating the imported malaria patients,and to guarantee no imported secondary cases.

Objective To analyze the results of inspection certification on malaria elimination in Baise City,and summarize the experiences of malaria elimination at a prefecture level. Methods According to Evaluation Schemes of Malaria Elimination (2014 edition)and Municipal Evaluation Schemes of Malaria Elimination in Guangxi(2016 edition),the malaria elimination work in Baise City was evaluated. In addition,2 counties(cities,districts)in the administrative region of Baise City were ran-domly selected for review assessment. Then the assessment and certification results were analyzed. Results The score of evalua-tion on malaria elimination in Baise City was 95.80,and the scores of review in Tiandong County and Jingxi City were 94.70 and 90.60,respectively. According to the weight of the three scores,namely 0.4,0.3,0.3,the final score of malaria elimination in Baise City was 93.91,which reached the national standards of malaria elimination score(more than 85). Conclusions Baise City has passed the inspection certification of malaria elimination by the authority of Guangxi Zhuang Autonomous Region. How-ever,the malaria monitoring post-elimination still should continue to consolidate the elimination achievements.

Objective To explore the law and distribution characteristics of malaria prevalence in Pingguo County,Guangxi Zhuang Autonomous Region,so as to provide the evidence for formulating the targeted control strategy and measures after malar?ia elimination. Methods The data of malaria epidemic situation in Pingguo County from 1951 to 2014 were collected and ana?lyzed with the retrospective epidemiological method. Results From 1951 to 2014,there were 71 365 malaria cases reported in the county. The malaria incidence dropped from 429.43/10 000 in 1960 to 0 in 1993. Since 2002,there was no local endogenous infection case reported. In 1993,this county achieved the standard of malaria elimination basically,and in 2014,passed the ex?amination and evaluation of malaria elimination. Conclusions In Pingguo County,the comprehensive malarial control strategy is effective in different stages. In the future,the monitoring of mobile population and dealing with imported malaria cases timely is the key of consolidation of malaria control achievements.

Objective To study the mechanism of enhancing effect of pretreatment with Geqin Tablets (GT). Methods The rat preconditioning models of myocardial ischemia were established by an improved pushing tube method. Cell apoptosis was determined with TUNEL. The expression of PKC was examined by immunohistochemical method. The serum SOD activity was tested by hydroxylamine hydrochloride method and MDA activity by TBA method. Results The amount of apoptotic cells increased in ischemia /reperfusion (IR) group significantly(P

Objective To understand the schistosomiasis epidemic and control history in Jingxi City,so as to provide the ev-idence for improving the future work. Methods The data of schistosomiasis prevention and control work were collected and ana-lyzed comprehensively in Jingxi City from 1956-2015. Results From 1956,the schistosomiasis prevention and control work car-ried out,and in 1985,Jingxi City reached the standard of schistosomiasis transmission interrupted and no local schistosome in-fected residents and livestock were found for 36 years. In May 2016,the city reached the national standard of Schistosomiasis Elimination Assessment Review. The cumulative number of schistosomiasis detection of residents was 348801 person-times, and 10434 schistosomiasis patients were found. The cumulative number of schistosomiasis detection of cattle was 20674 head-times,and 590 schistosome infected cattle were found. The cumulative schistosomiasis treatment number of residents was 18739 per-son-times,and 512 cattle were treated. The cumulative detection area with Oncomelania hupensis was 65213.25 hm2 ,and 353.80 hm2 area with O. hupensis snails was found. Conclusions Jingxi City has reached the standard of schistosomiasis elimi-nation,but there is still recurrence of O. hupensis snails,and the imported infection source exists. Therefore,we should strength-en the monitoring of floating population.

Objective To investigate the effect of schisandrin (SCH) treatment on learning and memory abilities and their mechanism in APP/PS1 dual transgenic dementia mice,and explore the effect of Chinese medicine on Alzheimer's disease (AD).Methods Thirty-five APP/PS1 dementia mouse models were randomly assigned into APP/PS1 model group (n=17) and APP/PS1+SCH group (n=18);another 10 male C57BL/6J mice were chosen as blank control group.The mice in the APP/PS1+SCH group were given intragastric administration of SCH at 2.6 mg/(kg· d) for 30 d;the mice in the APP/PS1 model group and blank control group were treated with distilled water for 30 d.The learning and memory abilities of these APP/PS1 mice (n=7) were detected by Morris water maze.Mice from the three groups were sacrificed;Nissl staining was used to observe Nissl bodies of neurons in brain tissues;real-time fluorescence quantitative PCR (qPCR) was used to detect the mRNA content of terminal glycosylationend products receptor (RAGE) in brain tissues;Western blotting was used to detect the expressions of RAGE and phosphorylated P38 mitogen-activated protein kinase (p-p38) in brain tissues.Results (1) The results of water maze space exploration experiment showed that the times of crossing the platform area in the three groups were statistically significant (P＜0.05);as compared with the APP/PS1 modelgroup,the times of crossing the platform area in the APP/PS1+SCH group were significantly increased (P＜0.05).(2) Nissl staining results showed that the contents of Nissl bodies in the hippocampal CA1 area and cortical neurons of the APP/PS 1 model group were significantly reduced,with light staining and cell body atrophy;the lesions in mice of the APP/PS1+SCH group were less severe than those of APP/PS1 model group,some neurons were atrophic,and the content of the neuronal nileite bodies in the hippocampal CA1 region was relatively abundant.(3) The qPCR results showed that there were statistically significant differences in RAGE mRNA expression levels in the cortex and hippocampus of the three groups (P＜0.05);as compared with the APP/PS1 model group,the APP/PS1+SCH group had significantly reduced RAGE mRNA expression in the hippocampal area (P＜0.05).(4) Western blotting results showed that RAGE and p-p38 protein expression levels in two parts of mice of APP/PS1+SCH group were significantly reduced as compared with those in the APP/PS1 model group (P＜0.05).Conclusion SCH may improve the functional status of hippocampal and cortical neurons and improve the spatial exploratory memory ability of APP/PS1 mice by down regulating the RAGE and P38 expressions.
