Differential etiology of posttraumatic stress disorder with conduct disorder and major depression in male veterans.

BACKGROUND: Epidemiologic studies reveal that posttraumatic stress disorder (PTSD) is highly comorbid with both conduct disorder and major depression in men. The genetic and environmental etiology of this comorbidity has not been examined. METHODS: Data were analyzed from 6744 middle-aged male-male monozygotic and dizygotic twins from the Vietnam Era Twin Registry. Conduct disorder, major depression, and PTSD were assessed via telephone interview using the Diagnostic Interview Schedule for the DSM-III-R in 1992. Structural equation modeling was used to estimate additive genetic, shared environmental, and individual-specific environmental effects common and specific to conduct disorder, major depression, and PTSD. RESULTS: The association between conduct disorder and PTSD was explained primarily by common shared environmental influences; these explained 10% (95% confidence interval: 6%-17%) of the variance in PTSD. The association between major depression and PTSD was largely explained by common genetic influences; these explained 19% (95% confidence interval: 11%-26%) of the variance in PTSD. CONCLUSIONS: Our findings suggest that different etiologic mechanisms explain the association of conduct disorder and major depression with PTSD in male veterans. If replicated in other populations, results suggest research aimed at identifying specific genetic and environmental factors that influence PTSD may benefit from starting with those that have been more consistently and strongly associated with major depression and conduct disorder.     

介绍一种自主研发的治疗腰椎滑脱的新型复位系统

[目的]评价运用作者自主研发的滑脱复位系统治疗峡部不连性腰椎滑脱症治疗效果,改变手术操作顺序,对神经根彻底减压提高治疗效果。[方法]对62例腰椎峡部不连性滑脱病人采用本系统加SRS治疗回顾和分析,并按复位效果、症状改善、椎间植骨融合,内固定材料牢固情况进行疗效评价。[结果]术后经1-6年（平均2年5个月）随访,根据NaKai评分标准优43例,良16例,可3例,无症状加重病例。无内固定松动断裂发生。[结论]新型滑脱复位系统加SRS治疗峡部不连性腰椎滑脱症效果更为切实可靠,尤其对患有骨质疏松以及腰椎滑脱严重的病人能达到很好的复位及固定效果,更容易直视下打入椎弓根钉,可防止对神经的误伤、节约了手术时间并可减少术中出血,手术操作方法简便,效果满意。     

肝炎和肝硬化患者胆囊超声改变的观察与分析

目的 :研究肝炎肝硬化患者胆囊彩色B超声像图变化 ,并探讨其临床意义。方法 :采用彩色超声诊断仪对 139例肝炎和肝硬化患者及 4 2例非肝炎体检者进行胆囊超声检查。结果 :慢性肝炎、重型肝炎、肝硬化患者组与非肝炎对照组彩色B超胆囊异常率比较均差异显著 (P <0 .0 1)。重型肝炎、肝硬化组与慢性肝炎组之间胆囊异常率也存在明显的差异 (P <0 .0 5 )。结论 :慢性肝病患者胆囊异常与胆囊本身炎症无关。胆囊声像图的改变对判断肝脏实质性病变的严重程度及指导临床治疗有一定的参考价值。     

低剂量混配农药对家兔血浆谷胱甘肽过氧化物酶和一氧化氮的影响

目的 探讨低剂量混配农药对家兔脂质过氧化及一氧化氮（NO）浓度的影响及意义。方法 将家兔随机分为6个混配农药染毒组、1个丙溴磷染毒组和1个对照组，于不同的时间测定各组血清胆碱酯酶（ChE)活力、谷胱甘肽过氧化物酶（GSH-Px)活力及一氧化氮（NO）浓度。结果 除较高剂量混配农药组外，其余各组染毒后的ChE活力均大于对照组实验前平均值的70%。随着染毒时间的延长农药混配组血浆GSH-Px活力高于或显著高于同时间的单剂量组和对照组，而血浆NO的浓度则呈降低趋势。结论 低剂量含有机磷的混配农药在导致ChE活力降低之前即可造成脂质过氧化增强和NO浓度的降低。     

不同置换液量血液透析滤过治疗尿毒症皮肤瘙痒疗效观察

目的：观察不同置换液量血液透析滤过(HDF)对尿毒症皮肤瘙痒的治疗作用。方法：将30例并发皮肤瘙痒的维持性血液透析尿毒症患随机分为三个组，分别接受高置换液量后稀释HDF(置换液20L)、低置换液量后稀释HDF(置换液10L)和高通量血液透析治疗。均使用F60透析器，隔日1次，连续3次，其余治疗条件相同。对皮肤瘙痒症状定量计分，比较三组病人治疗前后皮肤瘙痒症状积分的改变以及血磷和甲状旁腺激素(PTH)的变化。结果：高置换液量HDF组治疗后皮肤瘙痒积分明显下降，有统计学意义。其余两组无差异。以皮肤瘙痒积分下降50％为有效计算，高置换液量HDF组7例有效，有效率70％；低置换液量HDF组3例有效。有效率30％；透析组1例有效，有效率10％。三组间比较有统计学差异。三组透析后血磷均明显下降，有统计学意义；PTH亦有下降，HDF组有统计学差异，HD组无统计学差异。结论：增加置换液量可以提高HDF治疗尿毒症皮肤瘙痒的疗效；HDF治疗尿毒症皮肤瘙痒疗效优于高通量血液透析；HDF清除PTH的效果高于HD。     

直视下经尿道内切开术治疗尿道狭窄

目的：探讨直视下经尿道内次切开术治疗尿道狭窄的有效性和安全性。方法：总结直视下经尿道内切开术治疗68例尿道狭窄和闭锁患者的疗效和经验，63例1次手术成功；3例行2次、2例行3次成功。结果：68例中，57例术后随访3～71个月，平均28．3个月，43例(75％)均排尿通畅；2例暂时性尿失禁者分别于术后3～6月内恢复。结论：直视下经尿道内切开术创伤小，并发症少，疗效确切，是尿道狭窄和闭锁的首选治疗方法。     

The prevalence of LRRK2 Gly2385Arg variant in Chinese Han population with Parkinson's disease.

We conducted a case-control study to determine the prevalence of the LRRK2 Gly2385Arg variant in patients with Parkinson's disease in Han population in mainland China. Heterozygous LRRK2 Gly2385Arg variant was identified in 14 of 235 patients with Parkinson's disease (5.69%), but not in 214 unrelated healthy controls. Multivariate analysis indicated the frequency of Gly2385Arg variant in the female patients with early age at onset is higher than their male counterparts. The founder haplotype analysis showed the variant carriers shared the same founder. Clinically, the LRRK2 Gly2385Arg carriers presented with classical Parkinson's disease symptoms. Our study indicates that the LRRK2 Gly2385Arg variant is a potential ethnic-specific genetic risk factor of Parkinson's disease within Chinese Han ethnicity.     

免疫接种服务中一次性注射器处理方法及成本分析

利用山东省和陕西省现场调查资料,分析了2省不同层次医疗机构的一次性注射器的处理方式,并通过计算不同处理方式的成本,提出具有成本效果的一次性注射器的处理方式。结果表明:消毒/毁形、焚烧、掩埋和回收是主要的处理方法,在被调查的所有医疗机构中,没有一家医疗机构使用安全盒处理使用过的一次性注射器。由于没有使用规定的焚烧设备,实际调查结果表明,焚烧和掩埋的处理成本相对较低,是目前在村卫生室水平最适合的一次性注射器处理方法,而对于乡级和县级卫生机构而言,消毒/毁形和回收是目前较为适宜的处理一次性注射器的方法。
