目的 观察广州花都地区新冠疫情发生前后呼吸道肺炎支原体（MP）感染的流行病学特征,分析2018年—2019年（疫情前）和2020年—2021年（疫情后）期间的流行病学特点,为降低本地区的MP感染提供预防医学依据。方法 收集2018年1月—2021年12月于广州市中西医结合医院就诊的呼吸道感染患者51 005例,采用胶体金法检测血Mp- IgM抗体,对疫情前后年度、季节、性别和年龄段MP感染情况进行回顾性分析。结果 51 005例呼吸道感染患者中,MP感染总阳性率12.03%（6 134/5 1005）,新冠疫情发生前（2018—2019）阳性率为19.11%（5 161/27 010）,高于新冠疫情后（2020—2021）MP阳性率为4.06%（973/23 995）（χ²=2 721.32,P<0.001）。2018年和2019年（疫情前）不同季节MP检出率分别为：春季11.87%和17.76%,夏季13.26%和22.21%,秋季17.93%和24.59%,冬季14.20%和14.47%,以夏秋季阳性率高于春季和冬季;疫情后两年四季MP感染率均低于疫情前（P<0.001）,春季和冬季阳性率略高于夏秋季节。4年来呼吸道感染患者中MP感染率男性（13.87%）与女性（14.09%）比较差异无统计学意义。且疫情前（18.91%,19.28%）显著高于疫情后（2.49%,2.69%）,同时期不同性别阳性率比较差异无统计学意义。婴幼儿组（0~6岁）,学龄儿童组（>6~14岁）,青少年组（>14~30岁）,中青年组（>30~60岁）及老年组（>60岁）MP阳性检出率分别为20.89%、29.98%、9.29%、5.55%和4.57%,不同年龄组间MP感染率差异有统计学意义（P<0.05）,以学龄期儿童多见,其次为婴幼儿。结论 新冠疫情前后4年MP感染流行特点为：新冠疫情前后MP感染无性别差异;学龄期儿童和婴幼儿是高发人群;一年四季均可发病,疫情前两年夏秋季高发,疫情后两年四季发病率均较低且差异变小;新冠疫情下广州花都地区MP感染率显著低于疫情前,2019-nCov防控措施（佩戴口罩等）也减少了MP感染。

目的 分析儿童肺炎支原体肺炎（MPP）合并EB病毒（EBV）感染的临床表现及危险因素,以期进一步提升疾病预防及治疗有效率。方法 分析2020年4月—2022年4月间于我院进行入院治疗的MPP合并EBV感染患儿基本资料,选择84例进行研究,另选择单一EBV感染患儿作为对照组,对比两组患儿临床表现差异及各项指标,分析合并感染的危险因素。结果 一般资料上,研究组患儿低体质量、免疫力低下、流行病接触史占比均高于对照组,数据差异存在统计学意义（P<0.05）;临床表现上,研究组患儿高热、发热时间≥10 d、呼吸困难、胸腔积液、侵犯多肺叶占比及白细胞、淋巴细胞指标均高于对照组,血小板、Hb低于对照组,数据差异存在统计学意义（P<0.05）;经多因素分析发现,低体质量、免疫力低下、流行病接触史、高热、发热时间≥10 d、呼吸困难、胸腔积液、侵犯多肺叶、白细胞、血小板、Hb、淋巴细胞是MPP合并EBV感染的重要危险因素（P<0.05）。结论 儿童MPP合并EBV感染临床病症表现明显,且相较于单一EBV感染症状更为严重,医务人员需要根据患儿表现及相关危险因素及时予以准确诊断,对患儿实施针对性有效治疗,提升疾病治疗有效率。

目的 研究以尼尔·诺丁斯关怀理论为基础的全程护理在病毒性脑炎（VE）患儿中的干预效果。方法 选取我院2020年4月—2022年4月收治的VE患儿88例,以随机抽签法分为对照组（44例）、观察组（44例）,对照组采用常规护理,观察组在此基础上实施以尼尔·诺丁斯关怀理论为基础的全程护理。比较2组治疗依从性、恢复情况、儿童抑郁障碍自评量表（DSRSC）、儿童焦虑性情绪障碍筛查表（SCARED）、生存质量[儿童生存质量普适性核心量表（PedsQLTM4.0）]及家属护理满意度。结果 观察组治疗依从性100.00%（44/44）高于对照组86.36%（38/44）（P<0.05）;干预后,观察组DSRSC、SCARED评分低于对照组,PedsQLTM4.0评分高于对照组（P<0.05）;干预后,观察组FMA、MMSE评分较对照组升高（P<0.05）;观察组家属护理满意度97.93%（43/44）高于对照组81.82%（36/44）（P<0.05）。结论 以尼尔·诺丁斯关怀理论为基础的全程护理可改善VE患儿心理状态,提高治疗依从性,促进身体康复,进而提高患儿生存质量及家属护理满意度。

目的 分析安氏Ⅲ类错牙合正畸治疗牙合患者中切牙牙根及牙槽骨形态变化的影响。方法 分析2020年1月—2021年12月于我院口腔科进行正畸治疗的23例安氏Ⅲ类错牙合患者基本资料,对患者予以治疗前后的对锥形束CT测量,记录并对比相关数据,分析正畸治疗对于患者中切牙牙根及牙槽骨的影响。结果 （1）治疗后牙体及牙根长度较治疗前明显减小;（2）患者在治疗后唇、舌侧牙槽骨宽度呈下降趋势,与其他位点相比,上下颌舌侧中牙槽骨更易出现牙根吸收;下颌唇侧中牙槽骨宽度增加明显;（3）治疗后唇、舌侧牙槽骨缺损高度上有所增加,骨开窗、骨开裂位点增多。结论 安氏Ⅲ类错牙合有一定概率会出现牙根吸收等损伤,定期对患者实施锥形束CT检查能够为医生提供清晰准确图像资料支持,帮助医生更好判断患者状况并及时调整和优化治疗方法,以此进一步改善患者预后。

目的 探究3D打印数字化塑形聚醚醚酮（PEEK）材料在颅骨修补个体化重建中的应用效果。方法 收集我院90例行颅骨修补个体化重建手术患者（2019年1月—2021年1月）,按术中应用的颅骨修补材料不同分成PEEK组（n=30）、钛网（TM）组（n=60）。2组均行颅骨修补个体化重建术。对比2组围术期指标、手术前后简易智力状态量表（MMSE）、格拉斯哥预后评分（GOS）、颅骨缺损塑形满意度、并发症发生率、材料生物相容性及患者主观感觉情况。结果 与TM组相比,PEEK组住院时长更短、治疗费用更高（P<0.05）;与术前相比,2组术后、6个月、12个月、18个月MMSE、GOS评分均升高,其中PEEK组升高幅度比TM组更为多（P<0.05）;PEEK组总满意度为93.33%,与TM组的80.00%比较差异无统计学意义（P>0.05）;PEEK组并发症总发生率为6.67%,与TM组的15.00%比较差异无统计学意义（P>0.05）;PEEK组材料生物相容性及患者主观感觉情况与TM组比较差异无统计学意义（P>0.05）。结论 3D打印数字化塑形在颅骨修补个体化重建中,应用PEEK材料治疗费用更高,但可有效减少并发症,缩短住院时长,改善认知功能及预后,提升颅骨缺损塑形满意度,且材料生物相容性高,震动感和冷热感觉体验少。

目的 分析接受自体动静脉内瘘（AVF）维持性血液透析（MHD）尿毒症患者AVF使用寿命的影响因素,以期为临床延长AVF使用寿命提供可参考依据。方法 选取我院2019年1月—2021年2月期间收治的接受AVF的367例MHD尿毒症患者为研究对象,随访1年,统计AVF功能丧失状况,将AVF功能丧失患者纳入丧失组,AVF通畅患者纳入通畅组,分析AVF使用寿命的影响因素。结果 随访1年,AVF通畅率为80.65%（296/367）,功能丧失率为19.35%（71/367）;不同糖尿病、血液透析中低血压（IDH）、血磷、低密度脂蛋白、钙磷乘积、高凝倾向、前壁动静脉内径、血肿状况为AVF MHD尿毒症患者的AVF寿命存在差异（P<0.05）;经COX回归模型分析显示,糖尿病、IDH、血磷≥2.04 mmol/L、低密度脂蛋白>2.38 mmol/L、高凝倾向、血肿、前壁动静脉内径<2 mm为AVF MHD尿毒症患者AVF功能丧失的独立危险因素（P<0.05）。结论 AVF MHD尿毒症患者AVF使用寿命受糖尿病、IDH、血磷≥2.04 mmol/L、低密度脂蛋白>2.38 mmol/L、高凝倾向、血肿、前壁动静脉内径<2 mm等因素影响,临床可针对性制定干预措施以延长AVF使用寿命。

目的 分析药物性牙龈增生（DGO）治疗中半导体激光及牙周基础治疗的应用效果,以期进一步提升DGO治疗有效性,促使患者快速康复。方法 分析于我院进行治疗的88例DGO患者基本资料,按照入院顺序使用奇偶号法将其等分为各44例的对照组和研究组,予对照组患者实施常规牙周基础治疗,予研究组患者实施牙周基础治疗联合半导体激光治疗,对比2组治疗相关数据。结果 治疗前2组患者牙龈增生指数（GHI）比较差异无统计学意义（P>0.05）,经过治疗,研究组患者各阶段GHI均低于对照组,差异存在统计学意义（P<0.05）;治疗前2组患者龈沟出血指数（SBI）、探诊深度（PD）以及菌斑指数（PLI）比较差异无统计学意义（P>0.05）,经过治疗研究组各项治疗评分均比对照组更为理想,差异存在统计学意义（P<0.05）;治疗后研究组总有效率为97.73%,对照组总有效率为81.82%,差异存在统计学意义（P<0.05）。结论 对DGO患者实施牙周基础治疗下的半导体激光干预能够在更大程度上改善患者病情,同时缩短治疗周期,提升治疗总有效率,应用效果理想,可在临床推广使用。

我国结直肠癌的发病率与死亡率逐年增加,约10%~30%新发结直肠癌患者可表现为急性肠梗阻,其中梗阻发生率较高的主要部位是左半结肠。急性梗阻性左半结肠癌患者的主要治疗方式仍是急诊手术（ES）,但术后并发症发生率及围手术期死亡率较高,自膨式金属支架（SEMS）被一些指南推荐为梗阻性结肠癌的初始治疗选择,SEMS可将部分ES转变为择期手术,支架置入后择期手术（SBTS）与ES相比不仅可改善患者的短期生存结局,且支架置入后新辅助化疗为梗阻性结肠癌的治疗提供了新的途径;就长期生存结果而言,选择SBTS还是ES存在一定的争议。对于支架置入后手术时机的选择尚未达成共识,有指南表明大约两周的短桥接间隔可使患者最大程度获益,因而可有效指导临床工作。肠道支架置入术目前看来是一种简单、有效的临时性或永久性的治疗手段。

In recent years, the incidence and mortality of colorectal cancer in our country have been increasing year by year．Around 10% to 30% of newly diagnosed colorectal cancer patients showed acute intestinal obstruction, which the left colon cancer has higher incidence．Emergency surgery（ES）is still the main treatment for patients with acute obstructive left colon cancer, but the incidence of postoperative complications and perioperative mortality are high．Self-expanding metallic stents（SEMS）can convert some emergency procedures into stent as bridge to surgery（SBTS）, which is recommended by some guidelines as the initial treatment option for obstructive colon cancer．SBTS can not only improve the short-term survival outcome of patients compared with ES, but also provide a new approach for the treatment of obstructive colon cancer with neoadjuvant chemotherapy after intestinal obstruction stent placement．The choice of SBTS versus ES is somewhat controversial in terms of long-term survival outcomes．There is no consensus on the timing of surgery after stenting, and current guidelines suggest that bridging intervals of approximately two weeks strike a balance between potential adverse events and long-term outcomes．At present, intestinal stenting is still a simple, feasible and effective temporary or palliative permanent treatment with few complications．

本文综述近10年中医传统疗法中通过穴位刺激预防与治疗老年患者骨折术后谵妄的研究概况。术后谵妄是老年患者骨折术后常见的并发症,不仅延长患者住院时间、增加经济负担,同时与骨折术后死亡并发症的发生密切相关。但是本病机制尚未明确,在临床治疗上难以达成共识。针灸等穴位刺激是中医药治疗脑病的独具特色的疗法,近年来有关穴位刺激防治老年骨折术后谵妄的报道越来越多,本文主要探讨不同的穴位刺激方法干预对骨折术后谵妄发生率的影响,包括传统刺激方式如毫针、电针、穴位注射、穴位敷贴和新针疗法如耳针、头针等,认为穴位刺激能够较好预防骨折术后谵妄发生,在治疗上也有较好疗效。以期为进一步临床研究与应用提供参考。

This article summarized the research of acupoint stimulation in preventing delirium after fracture surgery in elderly patients in recent 10 years．Postoperative delirium is a common complication in elderly patients after fracture surgery, which affects life extremely and increases economic burden．However, the mechanism of this disease haven't been revealed, and it is difficult to reach consensus on clinical treatment．Acupoint stimulation, like acupuncture, is a unique treatment of encephalopathy with traditional Chinese medicine．In recent years, there are more and more reports on acupoint stimulation therapy to prevent and treat delirium after fracture surgery in the elderly．This article mainly study the influence of different acupoint stimulation therapy on treatment of delirium after fracture surgery, including electroacupuncture, auriculotherapy, scalp acupuncture, acupoint injection and acupoint application, etc．It is believed that acupoint stimulation can prevent delirium after fracture surgery, so as to provide reference for further clinical research and application．
