下颌磨牙区即拔即种的临床疗效观察

目的 探究下颌磨牙区即拔即种的临床疗效。方法 选取2017年1月至2019年1月江门市口腔医院收治的60例需进行下颌磨牙区种植的患者随机分为A、B组,A组给予即拔即种,B组给予延期种植,比较两组留存率、浅蝶形骨吸收率、种植12个月后PIS指标及满意度进行评价。结果 随访12个月两组留存率均为100%,浅碟形骨吸收率A组前磨牙为16.67%、磨牙为22.22%,B组前磨牙为10.00%、磨牙为25.00%,差异均无统计学意义(P＞0.05),A组植入30个种植体,60个牙间乳头,其中3度29个、2度24个、1度7个,B组植入30个种植体,60个牙间乳头,其中3度14个、2度24个、1度22个,A组牙间乳头PIS指标优于B组,且A组牙间乳头PIS评分(2.36±0.52)较B组(1.87±0.48)显著提高,差异均具有统计学意义(P＜0.05),A组对治疗效果满意率为93.33%较B组66.67%显著提高,差异具有统计学意义(P＜0.05)。结论 对于下颌磨牙区缺牙患者可采取即拔即种的方法修复,缩短缺牙时间,促进咬合和咀嚼功能恢复,舒适且美观,提高患者的满意度,值得在临床上推广。     

嘉兴市新居民儿童心理发育行为问题及影响因素分析

目的调查嘉兴市新居民儿童心理发育行为问题及影响因素，为改善新居民儿童心理健康提供理论依据。方法随机抽取新居民儿童548例，本地儿童1248例，采用自编量表评估儿童家庭影响因素，长处与困难问卷评估儿童心理发育行为问题，心理痛苦温度计评估主观心理痛苦程度，儿童心理虐待与忽视量表评估家庭教养方式，社会支持量表评估社会支持程度。结果新居民儿童主观评定心理痛苦程度高于本地儿童（P=0.002）。新居民儿童亲社会化行为低于本地儿童（P=0.000），多动/注意缺陷问题高于本地儿童（P=0.011）。儿童忽视虐待量表本地儿童5个因子得分低于新居民儿童：责骂因子（P=0.000）、恐吓因子（P=0.000）、情感忽视因子（P=0.000）、教育忽视因子（P=0.000）、身体忽视因子（P=0.000）。社会支持量表本地儿童3个因子得分均高于新居民儿童：客观支持（P=0.032）、主观支持（P=0.000）、对支持的利用度（P=0.000）。新居民儿童在新居民儿童学校、混合学校、本地儿童学校的3类学校中亲社会化行为、忽视因子、虐待因子、社会支持均有统计学差异（均P＜0.05）。结论新居民儿童较本地儿童心理发育行为明显落后，良好的家庭教养方式和有效的社会支持系统能够更快更好地促进其身心发育。     

互动式歌唱表演对轻中度阿尔茨海默病患者抑郁、精神行为和运动训练参与率的影响

目的 观察互动式歌唱表演对轻中度阿尔茨海默病（AD）患者抑郁、精神行为症状及运动训练参与率的影响。方法 选取符合入组条件≥60周岁AD患者63例，随机分为研究组（31例）和对照组（32例）。所有受试患者常规药物治疗及常规运动训练，对照组接受被动性音乐治疗，研究组接受以互动歌唱为主的主动性音乐治疗，1次/d，每次1小时，每周训练5天，持续干预6个月。于治疗前、治疗1个月后、治疗3个月后、治疗6个月后分别采用康奈尔痴呆抑郁量表（CSDD）评分、阿尔茨海默病病理行为（BEHAVE AD）评分、参与率进行评估。结果 治疗1个月、3个月后，研究组CSDD评分较治疗前均降低（P<0.05）；治疗6个月后，研究组患者CSDD评分较治疗前、治疗1个月、3个月后均显著降低（P<0.05），且与对照组比较差异有统计学意义（P<0.05）。治疗1个月、3个月后，研究组BEHAVE AD评分较治疗前均降低（P<0.05）；治疗6个月后，研究组患者BEHAVE AD评分较治疗前、治疗1个月、3个月后均显著降低（P<0.05），且与对照组比较差异有统计学意义（P<0.05）。治疗6个月后，两组运动训练参与率组间比较差异有统计学意义（P<0.05）。结论 互动式歌唱表演可能对改善轻中度AD患者的抑郁和精神行为症状有着积极的疗效，同时对提高受试者运动训练的参与率可能有着更积极的疗效。     

河南省1例柬埔寨输入登革热病例的病原分子分型与全基因序列分析

目的鉴定河南省1例来自柬埔寨的登革热输入性病例的登革病毒(dengue virus,DENV)血清型和基因型及其序列特征和传播来源。方法患者血液标本来源于2019年国家疾病监测系统网络直报的登革热疑似病例。样品经快速检测DENV NS1抗原和IgM/IgG抗体,再提取血清中核酸,应用荧光RT-PCR法进行DENV血清型鉴定,同时用Vero和BHK-21细胞对血清标本进行病毒分离培养,阳性培养物扩增全基因组序列,进行序列系统进化分析。结果该病例实验室确诊为DENV 1型感染,并从血清标本中分离到病毒株,测序后拼接成全长10670 nt的全基因组序列,经系统进化分析,该病毒株属于DENV 1型基因Ⅰ型,与东南亚流行株具有较高同源性和较近亲缘关系。结论2019年河南省来自柬埔寨的输入性病例的病原体为DENV 1型基因I型,此为近年来东南亚输入我国的常见血清型和基因型。

Outcomes of Early Decompressive Craniectomy Versus Conventional Medical Management After Severe Traumatic Brain Injury: A Systematic Review and Meta-Analysis

This meta-analysis examined whether early decompressive craniectomy (DC) can improve control of intracranial pressure (ICP) and mortality in patients with traumatic brain injury (TBI).Medline, Cochrane, EMBASE, and Google Scholar databases were searched until May 14, 2015, using the following terms: traumatic brain injury, refractory intracranial hypertension, high intracranial pressure, craniectomy, standard care, and medical management. Randomized controlled trials in which patients with TBI received DC and non-DC medical treatments were included.Of the 84 articles identified, 8 studies were selected for review, with 3 randomized controlled trials s having a total of 256 patients (123 DCs, 133 non-DCs) included in the meta-analysis. Patients receiving DC had a significantly greater reduction of ICP and shorter hospital stay. They also seemed to have lower odds of death than patients receiving only medical management, but the P value did not reach significance (pooled odds ratio 0.531, 95% confidence interval 0.209–1.350, Z = 1.95, P = 0.183) with respect to the effect on overall mortality; a separate analysis of 3 retrospective studies yielded a similar result.Whereas DC might effectively reduce ICP and shorten hospital stay in patients with TBI, its effect in decreasing mortality has not reached statistical significance.     

Intermittent Internal Fixation With a Locking Plate to Preserve Epiphyseal Growth Function During Limb-Salvage Surgery in a Child With Osteosarcoma of the Distal Femur: A Case Report

Limb shortening is a problem associated with surgery for osteosarcoma of the lower extremity in adolescents, as the tumors frequently occur near the epiphysis. Herein we report the use of a less invasive stabilization system (LISS) and an intermittent fixation method to preserve the growth function of epiphysis in an 11-year-old patient with an osteosarcoma of the distal femur.The 11-year-old male presented with left knee enlargement and pain for 2 weeks, and magnetic resonance imaging (MRI) and biopsy were consistent with osteosarcoma of the left distal femur. After preoperative chemotherapy, en bloc tumor resection was performed with margins based on MRI findings preserving the epiphyseal growth plate, the tumor cavity was filled with inactivated bone and bone cement, and a LISS was used to stabilize the femur. Aggressive postoperative chemotherapy was given. Approximately 105 weeks after surgery radiography showed that the distal end of the plate had moved superior to the epiphysis along with bone growth. Locking screws were placed in the distal part of the LISS plate to stabilize the re-implanted bone, and external fixation was not needed.The patient was able to walk with the crutches 1 week postoperatively, and bear weight on the extremity 6 weeks postoperatively. At 6 years after surgery, the patient''s height had increased 52 cm, shortening of the affected limb was only 1 cm, and the circumference of the affected limb was 2 cm smaller than that of the contralateral limb. There was no significant discomfort in the affected limb, and there was no gait abnormality. The patient could jump and run, and could participate in sports including basketball and badminton to the same degree as his peers.In summary, the novel method of bone reconstruction and fixation provided good results in a child with an osteosarcoma of the distal femur. This fixation method preserves the osteogenic function of the epiphysis and restored bone integrity simultaneously, and provides good functional recovery.
