Objective To compare the clinical results of surgical and conservative treatment of acute patellar dislocations.Methods Retrospective analyzed the clinical data of 35 patients with acute patellar dislocations from June 2004 to October 2009,and divided the patients into 2 groups.One group with 18 patients underwent surgical treatments,and the other group with 17 patients underwent conservative treatments,record the number of relapses cases of both the two groups.A radiographic examination was performed in the evaluation of the patients,and the Kujala questionnaire was applied with the intention of analyzing the improvement of pain and quality of life.Results All patients were followed up for more than 12 months.(1) The conservative treatment group exhibited a higher number of recurrent dislocations (7 patients) (41.2％) than the surgical treatment group,which did not have any relapses (x2 =9.265,P =0.002).(2) The patellar tilt returned to normal in the surgical group,while 8 patients returned to normal in the conservative group,with statistical difference between groups (x2 =10.980,P =0.001).And the lateral shift ratio returned to normal in the surgical group,while 6 patients returned to normal in the conservative group,with statistical difference between groups(x2 =7.667,P =0.006).(3)The surgical treatment group obtained a significantly better mean score on the Kujala test than preoperative ((90 ± 5) vs.(58 ± 6),t =16.465,P ＜ 0.01) ; The conservative treatment group,compared with the preoperative,is not improved obviously ((72 ± 6) vs.(62 ± 8),t =0.943,P ＞ 0.05) ;Postoperative group comparison,surgical group was higher than that in conservative group,there was significant difference between two groups (t =12.256,P ＜ 0.01).Conclusion For acute patellar dislocation,surgical treatment can significantly restore patellar stability,improve the function of knee joint.

Objective To understand the awareness status of malaria control knowledge of primary and secondary school stu-dents in malaria endemic areas of Shandong Province,so as to provide the baseline information for formulating the malaria control strategy. Methods A cross-sectional survey was conducted in 5 TypeⅡmalaria-endemic counties in Shandong Province. A struc-tured questionnaire survey was administrated to students in primary and secondary schools. Results A total of 1 884 students were completed with the questionnaires and all were effective. The total awareness rate of malaria control knowledge was 65.9%, and 54.7% of the students knew the transmission route of malaria and only 31.5% of the students were aware of the preventive methods of malaria. There were significant differences of the awareness scores of malaria control knowledge among different malar-ia endemic areas but there were no significant differences between the awareness rates of male and female students and between two different education levels. Conclusions The awareness of malaria control knowledge of primary and secondary school stu-dents in Shandong Province is poor;therefore,the health education of malaria control knowledge for primary and secondary school students should be strengthened.

Cervical stump cancer is rare in clinic, which leads to insufficient understanding of it by clinicians. Radiotherapy alone is often used in the early stage, but the treatment mode has gradually changed recently. However, there is still no uniform treatment standard for residual cancer, and the prognostic differences of residual cancer patients under the new treatment mode have not been reported in real time. In order to improve the management of cervical stump, this article reviewed its clinical characteristics, treatment and prognosis.

Objective To understand the malaria epidemic situation and characteristics in Shandong Province in 2014,so as to provide evidences for taking targeted strategies and measures for malaria elimination. Methods The data of malaria epi?demic and malaria cases of Shandong Province in 2014 were collected from Information Management System for Infectious Dis?eases Report and Information Management System for Parasitic Diseases Control and Prevention. The epidemiological character?istics of malaria situation and the diagnosis and treatment of malaria cases were analyzed by Microsoft Excel 2007. Results A total of 150 malaria cases were reported in Shandong Province in 2014,which increased by 14.50% compared with that in 2013 (131 cases). All the cases were imported from other countries except one imported from Yunnan Province in China,and most of the imported cases were from Africa(142 cases,95.30%). All the cases were confirmed in Shandong Provincial Reference Labo?ratory and there were 121 cases(80.67%)infected with Plasmodium falciparum,16 cases(10.67%)infected with P. vivax,9 cases(6.00%)infected with P. ovale and 4 cases(2.67%)infected with P. malariae. The cases were mainly distributed in Tai’ an(40 cases,26.67%),Yantai(17 cases,11.33%),Weihai(13 cases,8.67%),Jining(11 cases,7.33%)and Heze(11 cases,7.33%)cities. Conclusions There have been no local malaria cases reported in Shandong Province in the continuous 3 years. However,the reported number of imported malaria cases shows an increasing trend in the province in recent years,and the species of infected Plasmodium are diverse. Imported malaria from other countries is the key of malaria control in Shandong Province at present.

Objective The purpose of this study is to investigate the apoptosis mechanisms of glioblasto-ma cell line U87 induced by sodium cantharidinate ( SCA) in vitro.Methods Growth inhibition of U87 by 0.625μg/mL,1.25μg/mL,2.5μg/mL,5μg/mL SCA at 24 h,48 h,72 h were analyzed by MTT assay respec-tively.Morphological changes of U 87 nuclear were detected by fluorescence microscope .U87 cell apoptosis and cell cycle arrest were detected after SCA treatment for 24 h and 48 h by flow cytometry.The changes of apoptosis-related genes Bcl -2,Bax,Caspase-3 expression were analyzed after 24 h of SCA treatment by RT -PCR as-say.Results MTT assay showed that growth inhibition of U 87 cell induced by SCA was accompanied with the in-creased drug concentration ,Hoechst33258 staining showed the morphology of apoptotic U 87 cells nucleui ,chromo-some condensation ,nuclear condensation ,some nuclear fragmentation and formation of apoptotic bodies .Flow cy-tometry showed that SCA could induce cell cycle arrest at the G 2/M phase,and could induce apoptosis of U87.RT-PCR results showed that after 24 h of SCA treatment caspase -3,bax expression of U87 was significantly higher than the control group(P<0.05),bcl-2 expression was significantly decreased (P<0.05),and P53 expression was not significantly increased(P>0.05).Conclusion Our results demonstrate that SCA can inhibit U87 pro-liferation and induce apoptosis of U 87 .

Objective To understand the malaria situation of Shandong Province in 2013,so as to provide the evidence for formulating targeted prevention and control strategy and measures. Methods The data of malaria cases of Shandong Province in 2013 were collected from the Information Management System for Infectious Diseases Report and Information Management Sys-tem for Parasitic Diseases Control and Prevention. The data of epidemiological characteristics of malaria situation and the diagno-sis and treatment of malaria cases were analyzed by Microsoft Excell2007. Results There were 131 malaria cases reported in 2013,all of them were imported cases,and 127 cases(96.95%)were imported from African countries. A total of 116 cases (88.55%)were falciparum malaria cases. Totally 97.71%of the cases were male and the average age of malaria cases was 39 years. A total of 61.83%of the cases were peasants and 65.65%of the cases only received junior high school education. The dis-tribution of malaria cases was concentrated in Tai’an City(32 cases),Yantai City(19 cases)and Weihai City(17 cases),total-ly acounting for 53.13%. There was no significant seasonal variation in the reporting time of the cases. The median time from on-set to seeing doctor was four days and the median time from seeing doctor to being diagnosed was one day. Totally 35.88%of the cases were misdiagnosed when the first visit to a doctor. All of the cases were laboratory confirmed and 100%of them received the standard treatment after diagnosis. Conclusions All of the malaria cases were imported cases in Shandong Province in 2013. To control the imported malaria in Shandong Province,it is necessary to further strengthen the multi-sectoral cooperation, health education,malaria screening and professional training.
