远程胎儿监护的临床应用

远程胎儿监护是应用互连网及计算机技术，孕妇在家中或远程监护终端将胎心监护图形传输到中央监护站，医生即可通过电脑或手机APP远程判读。对高危孕妇实行远程监护，便于及时发现胎儿宫内缺氧情况和及时处理，改善围产儿结局。     

延安地区泌尿系结石成分分析的研究

目的利用红外光谱法测定延安大学附属医院泌尿外科手术获得的泌尿系结石成分,探讨延安地区泌尿系结石成分与年龄、性别等关系,比较上、下尿路结石成分特点,分析延安地区泌尿系结石发生的流行病学情况,为临床制定有效的个体化治疗及预防措施提供参考依据。方法收集2013年1月至2017年1月在延安大学附属医院泌尿外科治疗1984例尿路结石患者的年龄、性别、结石部位等临床资料,对比分析延安地区泌尿系结石在不同年龄、不同性别、不同解剖部位的分布特点。结果在1984例泌尿系结石的患者中,按每10岁年龄大小分组排序,统计各年龄阶段泌尿系结石发病情况,男性患者有1346例,女性患者有638例,男性年龄(50.23±14.48)岁,女性年龄(47.87±14.51)岁,男、女患者比例约2.11∶1。在66~75岁年龄段,尿路结石发病率性别差异具有统计学意义(P<0.05)。结石成分以混合性结石为主,以混合性结石为主,共1582例,占79.76%。其中1665例(83.92%)为上尿路结石,上、下尿路结石的比例为5.22∶1,其余为肾结石合并膀胱结石。上尿路结石中男性1062例,女性603例,男女比例为1.76∶1;下尿路结石中男性284例,女性35例,男女比例为8.11∶1。青壮年(年龄≤45岁)泌尿系结石患者草酸钙为主结石、感染性结石多见;中老年(年龄>45岁)泌尿系结石者草酸钙为主结石、尿酸类结石多见。感染性结石患者性别差异具有统计学意义(P<0.05)。结论在延安地区男性较女性更容易患泌尿系结石。同时,不同年龄段结石构成成分具有差异。对于年龄≤45岁患者,主要以草酸钙为主结石、感染性结石多见,这与结石整体发病率基本一致;而对于年龄>45岁患者,主要以草酸钙为主结石、尿酸性结石多见。表明对于不同年龄段的结石患者,可以根据上述结果在结石的预防和治疗上综合考量,给予明确而更加合理的治疗。

非小细胞肺癌新辅助靶向及免疫治疗研究进展和展望

肺癌是全球发病率和死亡率最高的恶性肿瘤。近年来,随着新型药物的出现和治疗模式的优化,肺癌患者的预后已有一定改善。新辅助治疗是指对潜在可接受手术切除的患者,先给予术前抗肿瘤治疗后再行手术治疗。新辅助治疗通过术前治疗可以缩小肿瘤体积,降低肿瘤分期;并且可以杀灭患者机体中循环肿瘤细胞及微转移病灶,令患者远期生存获益。靶向治疗及免疫治疗已被应用于晚期非小细胞肺癌(non-small cell lung cancer,NSCLC)的一线治疗。因此,有临床试验尝试将以上两种治疗手段应用于早期可切除NSCLC患者的新辅助治疗。本文针对新辅助靶向及免疫治疗对早期可切除NSCLC患者的疗效、治疗中的潜在风险予以综述,并探讨新辅助治疗的未来发展方向。

四方联动防跌护理在社区跌倒高危老年人中的应用

目的探讨专科护士-社区护士-个体-家庭四方联动防跌护理模式在社区跌倒高危老年人中的应用与效果。方法选取深圳市龙岗区的2个社区,随机分为观察组和对照组,从两个社区登记建档的跌倒高风险老年居民中分别随机抽选45名进行干预。观察组采用"专科护士-社区护士-个体-家庭"四方联动推进的综合干预方案。对照组接受社区防跌倒常规护理。于干预前及干预后12个月使用修订版社区老年人跌倒危险评估量表、步态和平衡测试量表对两组老年人进行评测,记录两组1年内跌倒发生例次。结果干预期间跌倒发生情况:观察组1人次,对照组6人次。观察组步态和平衡测试得分提高,跌倒危险评估表得分降低,与对照组比较,差异有统计学意义(均P0.01)。结论四方联动的综合干预方案应用于社区居家老年人,能有效降低老年人跌倒风险,提升其防跌能力,对预防社区老年人跌倒的发生有积极作用。     

Lucio phenomenon mimicking antiphospholipid syndrome: The occurrence of antiphospholipid antibodies in a leprosy patient

Lucio phenomenon is an atypical reaction of leprosy, characterized by vasculitic lesions that can mimic antiphospholipid syndrome (APS) clinically. Distinguishing the two can be difficult as antiphospholipid autoantibodies may be present in patients with leprosy. We report on a 32‐year‐old female patient presenting with a sudden onset of fever, hemorrhagic bullae, and skin necrosis on her lower legs. She was treated for APS due to the presence of antiphospholipid antibodies but had an inadequate response. A skin biopsy revealed thrombotic vasculopathy and necrotizing vasculitis associated with aggregation of foam cells in the perivascular area and subcutis, with acid‐fast bacilli in the histiocytes and blood vessel walls. Direct immunofluorescence showed IgM, C3, and fibrinogen deposition in the superficial and deep dermal blood vessels. The pathology confirmed the diagnosis of Lucio phenomenon, and appropriate therapy was given. It is essential to evaluate the patient comprehensively, including clinical, serological, and pathological aspects, to obtain the correct diagnosis.     

Effect of corneal stromal pocket irrigation in small-incision lenticule extraction

ObjectivesTo investigate the effect of corneal stromal pocket irrigation after small-incision lenticule extraction (SMILE) on visual acuity, intraocular pressure (IOP), corneal parameters and complications after surgery.MethodsA total of 242 eyes of 121 patients undergoing SMILE were enrolled in this prospective controlled study, and it was designed for one eye to randomly undergo SMILE with balanced salt solution irrigation of the corneal stromal pocket, while the other eye was not. The uncorrected distance visual acuity (UDVA) and slit lamp examination were recorded at 1 hour, 1 day, 1 week, and 1 month. Postoperative corneal density, corneal biomechanical, corneal endothelial cell number, and anterior OCT images were compared at 1 day, 1 week, and 1 month.ResultsCompared with the nonirrigation group, the irrigation group showed significantly higher UDVA at 1 day postoperatively (P < 0.05), but there was no significant difference during the rest of the postoperative period (1 hour, 1 week, and 1 month). In addition, no significant differences were found in IOP, corneal density, corneal biomechanics, corneal endothelial cells, and corneal morphology. No visual decline or severe postoperative complications were found in the patients in this study.ConclusionsInterlamellar irrigation did not affect IOP, corneal parameters, morphology, complications, or UDVA at 1 hour, 1 week, and 1 month after the operation, but it may promote UDVA 1 day after the operation.Subject terms: Refractive errors, Outcomes research, Surgery
