集束化干预联合闭环管理对ICU多重耐药菌感染的防控效果

目的 探讨集束化干预策略联合闭环管理模式对ICU多重耐药菌感染的防控效果。方法选取2020年1~12月EICU住院患者275例作为对照组，实施常规管理；2021年1~10月EICU住院患者239例作为观察组，在常规管理基础上实施集束化干预策略联合闭环管理。结果实施后，观察组多重耐药菌感染发生率明显低于对照组；患者住院日显著低于对照组，4项护理措施执行率(隔离标识、手卫生、环境消毒、医务人员相关知识知晓)、病原学送检率显著高于对照组（均P<0.05）。结论集束化干预联合信息化闭环管理可有效降低EICU多重耐药菌感染发生率。

Analysis on internal mechanism of zedoary turmeric in treatment of liver cancer based on pharmacodynamic substances and pharmacodynamic groups

Zedoary tumeric (Curcumae Rhizoma, Ezhu in Chinese) has a long history of application and has great potential in the treatment of liver cancer. The anti liver cancer effect of zedoary tumeric depends on the combined action of multiple pharmacodynamic substances. In order to clarify the specific mechanism of zedoary tumeric against liver cancer, this paper first analyzes the mechanism of its single pharmacodynamic substance against liver cancer, and then verifies the joint anti liver cancer mechanism of its "pharmacodynamic group". By searching the research on the anti hepatoma effect of active components of zedoary tumeric in recent years, we found that pharmacodynamic substances, including curcumol, zedoarondiol, curcumenol, curzerenone, curdione, curcumin, germacrone, β-elemene, can act on multi-target and multi-channel to play an anti hepatoma role. For example, curcumin can regulate miR, GLO1, CD133, VEGF, YAP, LIN28B, GPR81, HCAR-1, P53 and PI3K/Akt/mTOR, HSP70/TLR4 and NF-κB. Wnt/TGF/EMT, Nrf2/Keap1, JAK/STAT and other pathways play an anti hepatoma role. Network pharmacological analysis showed that the core targets of the "pharmacodynamic group" for anti-life cancer are AKT1, EGFR, MAPK8, etc, and the core pathways are neuroactive live receiver interaction, nitrogen metabolism, HIF-1 signaling pathway, etc. At the same time, by comparing and analyzing the relationship between the specific mechanisms of pharmacodynamic substance and "pharmacodynamic group", it is found that they have great reference significance in target, pathway, biological function, determination of core pharmacodynamic components, formation of core target protein interaction, in-depth research of single pharmacodynamic substance, increasing curative effect and so on. By analyzing the internal mechanism of zedoary tumeric pharmacodynamic substance and "pharmacodynamic group" in the treatment of liver cancer, this paper intends to provide some ideas and references for the deeper pharmacological research of zedoary tumeric and the relationship between pharmacodynamic substance and "pharmacodynamic group".     

Comparison between tension band and cerclage with X-Plate and lag screws in treatment of comminuted patellar fractures

BackgroundComminuted patellar fractures are not rare, and the ideal treatment method remains controversial. The present study was conducted to evaluate effects and compare complications of two different methods used to treat comminuted patellar fractures.MethodsFrom March 2010 to August 2016, 102 cases of 34-C2 or 34-C3 comminuted patellar fractures were treated at our hospital, wherein patients received two different treatments: titanium cable tension band with cerclage method (group A) and intrafragmentary screws with X-shaped plating technique (group B). At follow-ups, articular step-off, range of motion (ROM), Lysholm scores, time of union, and complications were recorded and analyzed. Radiographic and clinical data as well as rate of complications were statistically analyzed.ResultsIn total, 87 patients were included in the final analysis (n = 47 in group A and n = 40 in group B). No significant differences were noted in terms of cost of implant, age, gender, rate of 34-C3 fractures, rate of layered inferior pole fractures, postoperative articular step-off and union time. At 2-year follow-up, average Lysholm scores, ROM and rate of complications were (89.0 ± 4.5), (122°±12°) and (27.7%) in group A and (90.2 ± 3.9), (124°±11°) and (17.5%) in group B, respectively, with no significant differences (p > 0.05). The mean time of surgery in group B was shorter than that in group A with significant difference (p < 0.05).ConclusionsTreatment using the intrafragmentary screws and plate method for amenable comminuted patellar fractures achieved similar complication rate and favorable functional outcomes at the 2-year follow-up, which was comparable to the titanium cable tension band with cerclage method. Thus, the intrafragmentary screws and plate method is effective, safe and convenient for 34-C2/C3 comminuted patellar fractures, especially appropriate for patients with layered fragments.     

基于PERK-eIF2α-CHOP通路调控巨噬细胞胆固醇稳态及冠心康含药血清干预机制研究＊

目的 观察具有益气化痰活血作用的冠心康对人单核/巨噬细胞株THP-1细胞PERK-eIF2α信号通路及相关活化转录因子（ATF）和C/EBP同源转录因子（CHOP）的影响，探究冠心康对胆固醇在巨噬细胞内质网中的代谢稳态调节及作为“脂毒”流出后异常沉积的相关作用。方法 采用100 ng·mL^-1 PMA及80 μg·mL^-1氧化低密度脂蛋白诱导THP-1细胞株，构建巨噬细胞模型，并随机分为模型组、冠心康组、辛伐他汀组、正常组。分别采用10%小牛血清及含药血清干预模型细胞72 h后收集细胞。HE染色观察巨噬细胞病理形态变化，同时进行胆固醇及脂滴含量测定。分别采用Real-time PCR及Western blot法检测各组细胞PERK、eIF2α、ATF、CHOP mRNA及蛋白的表达。结果 HE染色观察到模型组细胞内呈现较多红色脂滴，经胆固醇含量测定，明显高于正常组，脂滴含量测定与前者一致（P<0.01）。模型组细胞ATF、CHOP基因表达水平均显著升高（P<0.01）。与模型组比较，冠心康组和辛伐他汀组细胞ATF、CHOP基因表达水平均显著降低（P<0.01）。PERK磷酸化以及CHOP蛋白表达水平在冠心康和辛伐他汀干预组表现为显著下调，与模型组比较，差异具有统计学意义（P<0.05）。结论 冠心康可能通过调控PERK-eIF2α-CHOP通路相关基因及蛋白，减少泡沫细胞形成，从而减轻内质网应激，维持细胞内胆固醇稳态，减少细胞内胆固醇沉积。
