贵州省"5+3"模式订单定向医学毕业生的离职意愿及影响因素研究

背景 我国基层全科医生的离职意愿较高，调查其离职意愿并分析影响因素，可以为减少基层卫生人才流失提供思路。目前，完成"5+3"模式（5年临床医学本科教育+3年住院医师规范化培训）培养的订单定向医学毕业生逐步履约进入基层工作，而针对该部分全科医生离职意向的研究相对较少。 目的 调查贵州省"5+3"模式订单定向医学毕业生回归基层工作后的离职意愿及影响因素，为完善吸引卫生人才留任、建设基层全科医生队伍相关政策提供依据。 方法 以贵州省截至2020年底已完成"5+3"模式培养并履约到基层医疗卫生机构工作的2015—2017级订单定向医学毕业生为研究对象。于2021-01-20至2021-02-10对其开展电子问卷调查，内容包括毕业生的一般情况、职业满意度、离职意愿、服务期满后职业方向。共回收问卷347份，其中有效问卷311份，问卷有效回收率为89.6%。采用单因素分析及多元逐步线性回归分析全科医生离职意愿的影响因素。 结果 贵州省"5+3"订单定向医学毕业生的整体离职意愿得分为（3.98±0.98）分，具有离职倾向者229例（73.6%）。不同性别、单位地理位置、每日工作量者的离职意愿得分比较，差异有统计学意义（P<0.05）。多元逐步线性回归分析显示，单位负责人对待下属的方式、在工作中获得的成就感、对当前收入满意程度、家人对工作的支持程度、当地激励政策执行程度是"5+3"订单定向医学毕业生离职意愿的影响因素（P<0.05）。服务期满后，计划留任原基层医疗卫生机构者12例（3.9%），计划去其他基层医疗卫生机构者21例（6.7%），计划离开基层去上级医院工作者196例（63.0%），计划攻读全日制硕士学位者60例（19.3%）。 结论 贵州省"5+3"模式订单定向医学毕业生的离职意愿较高，预计服务期满后基层全科人才流失较多，需从提高收入、重视全科医生心理需求、优化全科医生培养与使用、发展基层医疗卫生机构、加强全科宣传等方面着手改善。

miR-30c Impedes Glioblastoma Cell Proliferation and Migration by Targeting SOX9

miR-30c has been acknowledged as a tumor suppressor in various human cancers, such as ovarian cancer, gastric cancer, and prostate cancer. However, the role of miR-30c in glioblastoma (GBM) needs to be investigated. In our study, we found that the expression of miR-30c was significantly downregulated in GBM tissues and cell lines. We found that overexpression of miR-30c inhibited cellular proliferation of GBM cells in vitro and in vivo. More GBM cells were arrested in the G₀ phase after miR-30c overexpression. Moreover, we showed that miR-30c overexpression suppressed the migration and invasion of GBM cells. Mechanistically, we found that SOX9 was a direct target of miR-30c in GBM cells. Overexpression of miR-30c inhibited the mRNA and protein levels of SOX9 in GBM cells. Moreover, there was a negative correlation between the expression of miR-30c and SOX9 in GBM tissues. Finally, we showed that restoration of SOX9 in GBM cells reversed the proliferation, migration, and invasion of GBM cells transfected with miR-30c mimic. Collectively, our results demonstrated that miR-30c suppressed the proliferation, migration, and invasion of GBM cells via targeting SOX9.     

对比四维子宫输卵管超声造影与子宫输卵管造影评估输卵管通畅性效能:Meta分析

目的 采用Meta分析对比四维子宫输卵管超声造影（4D-HyCoSy）与子宫输卵管造影（HSG）评估输卵管通畅性的效能。方法 系统搜索PubMed、Cochrane Library、Embase、Web of Science、中国生物医学文献数据库、中国知网、万方医学网及维普数据库中建库至今有关4D-HyCoSy和/或HSG评估输卵管通畅性的文献。由2名研究人员依据纳入标准和排除标准筛选文献并提取信息；分别计算4D-HyCoSy和HSG评估输卵管通畅性的合并敏感度（SEN）、特异度（SPE）及诊断比值比（DOR），绘制综合受试者工作特征（SROC）曲线，获得曲线下面积（AUC），并以Medcalc 19.1.1统计软件比较AUC。结果 最终纳入19篇文献、1 358例疑似输卵管因素导致不孕患者，其中4篇同时采用4D-HyCoSy及HSG评估输卵管通畅性，10篇仅以4D-HyCoSy评估，5篇仅以HSG评估。Meta分析结果显示，4D-HyCoSy评估输卵管通畅性的合并SEN、SPE及DOR分别为0.92[95%CI（0.91，0.94）]、0.91[95%CI（0.89，0.93）]及115.06[95%CI（54.23，224.10）]；HSG评估输卵管通畅性的合并SEN、SPE及DOR分别为0.84[95%CI（0.81，0.87）]、0.80[95%CI（0.76，0.83）]及28.64[95%CI（10.08，81.35）]。4D-HyCoSy评估输卵管通畅性的AUC为0.98[95%CI（0.96，0.99）]，HSG为0.93[95%CI（0.90，0.95）]，差异有统计学意义（Z=6.97，P<0.01）。结论 4D-HyCoSy评估输卵管通畅性的效能高于HSG。

Association of PD-L1 gene rs4143815 C>G polymorphism and human cancer susceptibility: A systematic review and meta-analysis

Programmed death ligand 1(PD-L1) mediated immune escape play important roles in the development of cancer. The gene polymorphism of PD-L1, in particular rs4143815 C?>?G, has been associated with the cancer risks, but with conflicting results. Therefore, this meta-analysis was aimed to assess the association between rs4143815 C?>?G and cancer susceptibility. A systematic literature search was performed to select the studies and the pooled odds ratio (OR) with 95% confidence interval (CI) was used to evaluate the strength of association. Eleven eligible studies containing 3711 cases and 3704 controls were enrolled in the meta-analysis. The results suggested that there is a strong association between rs4143815 C?>?G and the cancer risks (G vs. C: OR?=?1.386, 95% CI: 1.132–1.696, p?=?0.002; GG vs. CG?+?CC: OR?=?1.843 95% CI: 1.300–2.613, p?=?0.002; GG?+?CG vs. CC: OR?=?1.280, 95% CI: 1.040–1.576, p?=?0.020). Subgroup analysis based on cancer type suggested that PD-L1 rs4143815 C?>?G might increase the susceptibility to gastric cancer (G vs. C: OR?=?1.842, 95% CI: 1.403–2.418, p?<?0.001) and bladder cancer (G vs. C: OR?=?2.015, 95% CI: 1.556–2.608, p?<?0.001), and genotype GG carriers of PD-L1 rs4143815 C?>?G might have higher risks of HCC (GG vs. CG?+?CC: OR?=?2.226 95% CI: 1.562–3.172, p?<?0.001). PD-L1 rs4143815 C?>?G might confer an increased cancer risk, indicating this SNP may contribute to the pathogenesis of cancer and might be used as a potential biomarker to predict the susceptibility to cancer.
