Personal comorbidities and their subsequent risks for liver,gallbladder and bile duct cancers

Many environmental risk factors for hepatobiliary cancers are known but whether they are associated with specific cancer types is unclear. We present here a novel approach of assessing standardized incidence ratios (SIRs) of previously diagnosed comorbidities for hepatocellular carcinoma (HCC), gallbladder cancer (GBC), cholangiocarcinoma (CCA) and ampullary cancer. The 13 comorbidities included alcohol and nonalcohol related liver disease, chronic obstructive pulmonary disease, gallstone disease, viral and other kinds of hepatitis, infection of bile ducts, hepatic and other autoimmune diseases, obesity and diabetes. Patients were identified from the Swedish Inpatient Register from 1987 to 2018, and their cancers were followed from 1997 onwards. SIRs for HCC were 80 to 100 in men and women diagnosed with hepatitis C virus and they were also >10 in patients diagnosed with hepatitis B virus, other kind of hepatitis, hepatic autoimmune disease and nonalcohol related liver disease. Many of these risks, as well as alcohol related liver disease, were either specific to HCC or were shared with intrahepatic CCA. For GBC, CCA and ampullary cancer infection of bile ducts was the main risk factor. Gallstone disease, nonhepatic autoimmune diseases and diabetes were associated with all hepatobiliary cancers. The limitations of the study include inability to cover some rare risk factors and limited follow-up time. Many of the considered comorbidities are characterized by chronic inflammation and/or overt immune disturbance in autoimmune diseases. The results suggest that local chronic inflammation and a related immune disturbance is the carcinogenic trigger for all these cancers.     

芫根调节免疫功能的小肠转录组学研究

利用生物信息学技术初步探索芫根调控肠道免疫功能的分子生物学机制。方法 选择雄性SPF级BALB/c小鼠18只，随机分为3组，每组6只。SC1组小鼠每只每次灌胃芫根提取液150 μL，SC2组小鼠每只每次灌胃绞碎芫根原浆悬液150 μL，NC组小鼠每只每次灌胃生理盐水150 μL，连续7 d每日灌胃一次。分别取每组小鼠小肠组织样品提取RNA，总RNA的质检合格后，进行转录组测序。按GO功能和KEGG信号通路对差异表达基因聚类分析揭示差异表达高度富集的免疫相关通路。从免疫角度分析芫根灌胃小鼠小肠组织的基因表达变化情况。结果 转录组测序共检测到27733条 mRNA的表达，SC1组与NC组比较，显著差异表达基因1635个，其中上调差异表达基因1236个，下调差异表达基因399个；SC2组与NC组比较，显著差异表达基因2872个，其中上调差异表达基因2233个，下调差异表达基因639个（P＜0.05）。按GO功能和KEGG信号通路聚类分析显示差异表达基因在白介素分泌、干扰素反应、T细胞受体信号通路及维生素和脂肪消化吸收等途径的富集度在两个芫根组中均居于前20位（P＜0.01），肠黏膜趋化因子CCL20和巨噬细胞极化标志物CD274等免疫蛋白编码基因差异表达显著且同属于上述多个免疫通路。结论 芫根灌胃小鼠小肠的差异表达基因在白介素分泌、干扰素反应、T细胞受体信号通路、营养物质消化吸收等途径高度富集，提示芫根对肠道免疫系统及肠黏膜功能的调节，其中CD274的表达上调和CCL20的表达下调提示诱导M1型巨噬细胞极化和T细胞活化可能是芫根调控免疫和维护肠道正常结构功能的重要途径。

早产儿早期神经运动干预研究进展

随着医疗救治水平的不断提高,早产儿的存活率明显增加,但早产常易伴发脑性瘫痪、运动和认知障碍等一系列神经发育问题,给家庭、社会带来沉重负担。生命早期大脑发育迅速,可塑性强,是进行早期运动干预的良好时机。本文就早产儿早期神经运动干预进行综述,旨在为临床医护人员对早产儿进行适宜有效的运动干预提供参考。     

多功能套针浮刺疗法治疗神经根型颈椎病——一项随机对照观察研究＊

目的 评价多功能套针浮刺疗法对神经根型颈椎病的临床疗效。方法 选取256例神经根型颈椎病患者，按随机数字表法分为观察组与对照组各128例。观察组应用多功能套针浮刺疗法进行干预，对照组为常规针刺治疗。两组患者均治疗7天。分别于治疗前后观察两组患者的简化McGill疼痛问卷（SF-MPQ）、国际标准颈椎功能障碍指数（NDI）和田中靖久颈椎病症状20分法量表评分，并于治疗结束后3个月观察复发率。结果 两组患者治疗后的SF-MPQ量表评分、NDI量表评分及田中靖久颈椎病症状20分法评分与治疗前相比均有改善（P<0.05），且观察组优于对照组（P<0.05）；两组患者于治疗后3个月随访，SF-MPQ量表评分与治疗后相比均有改善，且观察组优于对照组（P<0.05）；观察组临床疗效总有效率为96.88%，愈显率为81.25%；对照组总有效率为78.13%，愈显率为46.88%，观察组优于对照组（P<0.05）。结论 应用多功能套针浮刺疗法治疗神经根型颈椎病临床疗效显著，见效较快，可有效降低其复发率，且作用稳定，效果持久，值得临床推广应用。     

Impact of the COVID-19 pandemic on the hospital attendance of patients with primary cervical cancer in Heilongjiang,China

Information regarding the impact of the coronavirus disease 2019 (COVID-19) pandemic on cervical cancer in mainland China is lacking. We explored its impact on the hospital attendance of patients with primary cervical cancer. We included 1918 patients with primary cervical cancer who initially attended Harbin Medical University Cancer Hospital between January 23, 2019, and January 23, 2021. Attendance decreased by 31%, from 1135 in 2019 to 783 in 2020, mainly from January to June (𝜒² = 73.362, P < .001). The percentage of patients detected by screening decreased from 12.1% in January-June 2019 to 5.8% in January-June 2020 (𝜒² = 7.187, P = .007). Patients with stage I accounted for 28.4% in 2020 significantly lower than 36.6% in 2019 (𝜒² = 14.085, P < .001), and patients with stage III accounted for 27.1% in 2020 significantly higher than 20.5% in 2019 (𝜒² = 11.145, P < .001). Waiting time for treatment was extended from 8 days (median) in January-June and July-December 2019 to 16 days in January-June (𝜒² = 74.674, P < .001) and 12 days in July-December 2020 (𝜒² = 37.916, P < .001). Of the 179 patients who delayed treatment, 164 (91.6%) were for the reasons of the healthcare providers. Compared to 2019, the number of patients in Harbin or non-Harbin in Heilongjiang Province and outside the province decreased, and cross-regional medical treatment has been hindered. The COVID-19 pandemic has negatively impacted cervical cancer patient attendance at the initial phase. These results are solid evidence that a strategy and mechanism for the effective attendance of cervical cancer patients in response to public health emergencies is urgently needed.
