目的 分析2012年和2014年流行性腮腺炎(腮腺炎)流行特征,探讨山东省2剂次含腮腺炎成分疫苗(MuCV)接种的预防效果。方法 在一定模型假定基础上,结合相关文献设置合理参数,构建状态空间模型,利用迭代滤波对模型进行参数估计。结果 2012年和2014年托幼及学生人群基础再生数(R0)分别为4.49(95%CI:4.30~4.67)和2.50(95%CI:2.38~2.61)。结论 状态空间模型能够很好地描述腮腺炎传播过程;山东省实行2剂MuCV能够有效降低腮腺炎在人群中的传播;托幼和学生是实现腮腺炎进一步控制的重要人群,应进一步提高2剂次MuCV接种率。 相似文献

ObjectiveTo evaluate the effectiveness of inserting a retrievable inferior vena cava filter (IVCF) to prevent pulmonary embolism (PE) in patients with bone fractures and acute deep venous thrombosis (DVT) before major orthopedic surgery.MethodsClinical data of patients with fractures and acute DVT who underwent IVCF insertion were analyzed. The patients were divided into above-knee DVT (AKDVT), popliteal vein thrombosis (PVT), and below-knee DVT (BKDVT) groups.ResultsAn IVCF was successfully implanted in 964 patients, among whom 929 were followed up (335, 470, and 124 in AKDVT, PVT, and BKDVT groups, respectively). There was no significant difference in the incidence of filter thrombosis among the groups (11.04%, 11.70%, and 8.06%, respectively). No symptomatic PE occurred during follow-up. The mean filter indwelling time was 18.4 ± 4.3 days, and the total filter removal rate was 76.87%. There was no significant difference in the rate of filter implantation, retrieval, complications, or mortality among the groups.ConclusionsRetrievable filters can effectively prevent PE before orthopedic surgery in patients with fractures and acute DVT of the lower limbs. AKDVT more readily forms a ≥1-cm thrombus in the IVCF than does BKDVT, and PVT more readily forms a <1-cm thrombus than does AKDVT. 相似文献

With the development of social informatization, The incidence of dry eyes has increased,especailly amony people contacted with the video. General treatment can only relieve symptoms but not achieve the purpose of cure. Mesenchymal stem cells (MSCs), category of cells with multi directional differentiation potential,can be used to repair the damaged tissue and treat the genetic defective disease of mesenchymal tissue,and has broad prospect of clinical application.This article reviewed the current situation of MSCs treatment in the dry eye in clinical and experimental status,and discussed the possibility of MSCs treatment for the ophthalmoxerosis. 相似文献

The purpose of the study is to examine the safety and effectiveness of topical autologous platelet‐rich gel (APG) application on facilitating the healing of diabetic chronic refractory cutaneous ulcers. The study was designed as a prospective, randomized controlled trial between January 1, 2007 and December 31, 2011. Eligible inpatients at the Diabetic Foot Care Center of West China Hospital, Sichuan University (China) were randomly prescribed with a 12‐week standard treatment of ulcers (the control group) or standard treatment plus topical application APG (the APG group). The wound healing grades (primary endpoint), time to complete healing, and healing velocity within 12 weeks were monitored as short‐term effectiveness measurements, while side effects were documented safety endpoints. The rates of survival and recurrence within the follow up were recorded as long‐term effectiveness endpoints. Analysis on total diabetic ulcers (DUs) (n = 117) and subgroup analysis on diabetic foot ulcers (DFUs) (n = 103) were both conducted. Standard treatment plus APG treatment was statistically more effective than standard treatment (p < 0.05 in both total DUs and subgroup of DFUs). The subjects defined as healing grade 1 were 50/59 (84.8%) in total DUs and 41/48 (85.4%) in DFUs in the APG group compared with 40/58 (69.0%) and 37/55 (67.3%) in the control group from intent to treat population. The Kaplan‐Meier time‐to‐healing were significantly different between the two groups (p < 0.05 in both total DUs and subgroup of DFUs). No side effects were identified after topical APG application. The long‐term survival and recurrence rates were comparative between groups (p > 0.05). This study shows that topical APG application plus standard treatment is safe and quite effective on diabetic chronic refractory cutaneous ulcers, compared with standard treatment. 相似文献

目的 探讨山东省新型冠状病毒肺炎(COVID-19)的空间分布与相关影响因素,进一步了解山东省疫情的区域分布特征,为指导防控策略提供科学依据。 方法 收集2020年1月21日至3月1日山东省COVID-19确诊病例数及相关影响因素数据,采用地理加权广义线性模型(GWGLM)分析COVID-19确诊病例数及各影响因素间的空间异质性及其相关关系。 结果 对558例确诊病例的空间分布进行分析,广义线性模型(GLM)分析结果显示,人口密度、人均可支配收入、公共预算支出、湖北迁入规模占比和距武汉的空间距离均有统计学意义。人口越密集、人均可支配收入越高、公共预算支出越多,则确诊病例数越多;绝大多数县区的湖北迁入人口规模和距武汉的空间距离与确诊病例数呈负相关。GWGLM的R2为0.363,模型可解释COVID-19确诊病例数总变异的36.3%。 结论 GWGLM能够揭示COVID-19及其影响因素的空间异质性,有助于局域精准施策,应根据各因素的空间分布特征及其与确诊病例数的局域关系制定不同区域的分级防控措施。 相似文献
