    人民健康是民族昌盛和国家富强的重要标志,应放在优先发展的战略地位。坚持预防为主,倡导健康文明生活方式,预防控制重大疾病。然而,政府和个人的医疗负担愈加沉重,人均医疗费用快速增长的势头仍未彻底逆转。作为经济学与医疗的交叉学科,卫生经济学专注于如何解决有效配置医疗资源。针对重大疾病预防,权衡当期的预防费用支出和远期的产出,对科学地定量化地规划医疗政策具有重要作用,同时也将是未来的发展方向之一。宫颈癌是女性常见的恶性肿瘤,也是目前唯一病因明确、可以早期预防和治疗、可以消灭的癌症。HPV疫苗价格较高,不合理地推广使用无疑将加重政府和个人的医疗负担。为了优化医疗资源配置和寻找最优的宫颈癌预防策略,本研究...People's health is an important symbol of national prosperity, which should be put in the strategic position of priority development. We should adhere to prevention, advocate a healthy and civilized lifestyle and prevent major diseases. However, the per capita medical expense was still rising dramatically, which imposed heavy burdens to individuals, families, and society.

    人乳头状瘤病毒(HuMAn PAPIllOMA VIruS,HPV)持续感染引起宫颈癌、肛门癌和生殖器疣等多种HPV相关疾病。其中,宫颈癌和生殖器疣已严重威胁到人群的生命健康[1-6],其防治工作成为当前亟待解决的公共卫生问题。预防性HPV疫苗已经被证明可以有效阻断HPV感染和降低人群宫颈癌和生殖器疣发病率,并且其已在多个国家获得了使用许可[4]。HPV疫苗接种方案的经济学评估对科学规划HPV疫苗接种方案和优化卫生资源配置有着重要作福建省科技厅科技计划项目(2013R0091); 教育部人文社会科学研究项目(12YJA790030); 福建省自然科学基金计划资助项目(2012J01303

Methods The literatures on HPV detection of CA patients in mainland China published between January 1990 and December 2013 were systematically retrieved from Pub Med,Science Direct Online, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and the VIP database. According to the sample size,HPV infection rates of each literature were weighted and combined and the infection rates of HPV and the combined infection rate of each genotype of CA patients were calculated,and the combined infection rate of HPV of CA patients in different years and areas of study was analyzed. Multivariate Logistic regression analysis was used to investigate the influencing factors of CA patients infected / detected with HPV. Results A total of 67 literatures were included in the study. The number of CA patients accumulated to 10 757,and 9 328 cases(86. 7%) infected with HPV. The combined infection rate of HPV in patients with CA was 95. 7% 〔95% CI(95. 2%,96. 2%) 〕,and the top three genotypes with high infection rate were HPV6 /11 〔81. 2%,95% CI(77. 1%,85. 2%) 〕, HPV6 〔43. 8%,95% CI(35. 2%,52. 5%) 〕, HPV11〔38. 3%,95% CI(32. 8%,43. 8%) 〕. The combined infection rate of HPV in patients with CA between 1990 and 2003 and between 2004 and 2013 was 96. 6% 〔95% CI(95. 8%,97. 5%) 〕and 94. 6% 〔95% CI(94. 0%,95. 3%) 〕respectively;the combined infection rate of HPV of patients in eastern, middle and western areas was 95. 1% 〔95% CI(94. 4%,95. 7%) 〕,91. 7% 〔95% CI(89. 3%,94. 1%) 〕,and 96. 5% 〔95% CI(95. 4%,97. 6%) 〕respectively. Multivariate Logistic regression analysis showed that the year of study,areas of study,type of specimen and methods of diagnosis significantly influenced the infection and detection of HPV in CA patients(P 0. 05).

    自噬诱导是肿瘤细胞对化疗药物抵抗性的原因之一,该研究探讨溶酶体抑制剂氯喹对喜树碱(camptothecin,CPT)诱导的宫颈癌细胞Si Ha死亡的增敏效果。CPT和/或氯喹处理宫颈癌Si Ha细胞,MTT法检测细胞增殖,DAPI和TUNEL染色观察细胞凋亡,Western blot和免疫荧光检测自噬及凋亡相关蛋白。结果发现,CPT处理后,Si Ha细胞MAP1LC3B荧光点和LC3II(microtubuleassociated protein light chain 3II)蛋白水平增加,p62荧光点和蛋白质水平则减少;而采用氯喹特异抑制自噬后,可明显提高CPT诱导的细胞凋亡、caspase-9的激活和PARP(poly ADP-ribose polymerase)的切割,而全长caspase-2水平显著下降。以上结果提示,氯喹可通过抑制细胞自噬而增强宫颈癌细胞株Si Ha对CPT诱导细胞凋亡的敏感性。The autophagy induction is one of the reasons for the resistance of tumor cells to chemotherapy drugs. In this study, the enhanced sensitivity of cervical cancer Si Ha cells to camptothecin(CPT)-induced cell death by chloroquine(a lysosome inhibitor) was investigated. The cell viability was detected by MTT assay, meanwhile, apoptosis was observed by DAPI and TUNEL, autophagy related proteins and apoptosis proteins were analyzed by immunofluorescence(IF) staining and Western blot in Si Ha cells after CPT treatment alone or combined with chloroquine. The results found that in Si Ha cells with CPT treatment the autophagy related protein LC3 foci and microtubule-associated protein light chain 3II(LC3II) protein level was increased, but p62 foci and protein level was decreased. When autophagy was inhibited by chloroquine, the CPT-induced apoptosis was obviously enhanced, and caspase-9 was activated and PARP was cleaved, but full length caspase-2 was decreased. Taken together, these results indicated that the inhibition of autophagy by chloroquine could sensitize cervical cancer Si Ha cells to CPT inducing cell apoptosis.山西省自然科学基金(批准号:2014021037-9);; 山西医科大学汾阳学院博士启动基金(批准号:1301);山西医科大学汾阳学院科研项目基金(批准号:1422)资助的课题~

    RGB images were taken by a drone-borne camera and analyzed using four-color indices to monitor and identify green tide in the coastal scenic area in Haiyang, Shandong. Monitoring indices in different locations were specified. The results show that the characteristic values of G-band are greater than the other bands' and the color indices could be used for green tide monitoring. For different places of the green tide outbreak, NGBDI (normalized green-blue difference) index is applicable for monitoring floating green tide at sea, and GLI (green leaf index) index for green tide monitoring on beach

    Since 2007, green tides(also called Ulva prolifera) occurred every summer in the Yellow Sea, causing ecological problems in the coastal environment of Shandong Peninsula . A large number of Ulva prolifera on shore will rot and stink if not handled in time,which seriously affects the tourism and the health of residents in coastal landscape. In order to improve the accuracy of monitoring green tide disasters, and to improve the efficiency of the cleaning up and disposal of Ulva prolifera at key prevention and control area, In this study, the high-precision image of UAV is used to monitor the green tide disaster in Yintan landscape of Rushan City. With the spectral characteristics of Ulva prolifera and coastal vegetation measured by spectroradiometer, four vegetation indices were used to analyze and identify the Ulva prolifera and coastal vegetation, and to verify the extraction of Ulva prolifera and coastal vegetation under different vegetation indices, and based on this extraction method, the biomass of coastal green tide algae was estimated. The results show that in the red-edge band,Ulva prolifera and coastal vegetation can be distinguished. MTCI(MERIS terrestrial chlorophyll index) is more suitale,with the accuracy of 91.3%, followed by SR_(redge),NDVI_(redge) and MSR_(redge),with the accuracy of 85.3%, 83.8% and 81.2%, respectively; Estimation model of biomass based on MTCI index showed that about 600 tons of Ulva prolifera were estimated in 300 m study area. An effective method for dynamic monitoring and cleaning up of green tide disaster is provided
