女性吸毒者心理防御机制及心理健康状况研究

目的探讨女性吸毒者的心理防御机制与心理状况及二者的关系.方法分别用防御方式问卷(DSQ)和症状自评量表(SCL-90),对110名女性吸毒者(研究组)和41名女大学生(对照组)进行调查.结果研究组不成熟防御机制、中间型防御机制和掩饰因子评分(4.83±0.97,4.99±0.75,5.98±1.17)显著高于对照组(3.95±0.68,4.26±0.73,5.41±1.34)(P＜0.01或P＜0.05);研究组SCL-90中9个因子评分均显著高于对照组(P＜0.01);相关分析发现,研究组不成熟防御机制与SCL-90中9个因子均存在非常显著正相关(P＜0.01),中间型防御机制与SCL-90中的强迫、偏执、躯体化、抑郁存在显著正相关(P＜0.01或P＜0.05),掩饰因子与SCL-90中的敌对、偏执、强迫呈显著正相关(P＜0.01或P＜0.05).结论女性吸毒者过多地使用不成熟防御机制及中间型防御机制,心理状况差,且二者存在明显的相关性.     

血液透析动脉穿刺术临床研究

目的:研究动脉穿刺技术,提高1次穿刺成功率。方法:将166例急、慢性肾功能衷竭接受血液透析的患者,随机分为观察组84例和对照组82例。观察组用新的穿刺方法,即先在动脉(桡动脉或足背动脉)搏动最明显或最清晰处按一印记,然后进针,对照组用传统的穿刺方法穿刺。比较两组所需时间、1次成功率、血流量、针眼处渗血、疼痛程度以及并发症。结果:两组穿刺所需时间、血流量、针眼处渗血,均有统计学意义(P<0.01)。结论:观察组用新的穿刺方法,能明显提高1次穿刺成功率,缩短穿刺时间,减轻患者痛苦,减少并发症发生。     

儿童安装永久性心脏起搏器方法的临床探讨

目的总结儿童永久性心脏起搏器植入、随访和并发症处理的经验。方法(1)对III度房室传导阻滞儿童植入永久性心脏起搏器,术后1周,1、3、6、12个月及此后每年均进行随访,随访时行心电图、胸片、心脏超声心动图检查,并对起搏器参数和起搏阈值进行检测。(2)对随诊中出现的6例并发症(其中囊袋感染2例、固定胶套磨破皮肤感染2例、绝缘层破损1例、重度三尖瓣反流1例)分别进行处理。结果对27例植入永久性心脏起搏器的儿童进行7个月~8年随访,平均(5.2±1.5)年;其中6例并发症经处理后,感知和起搏功能良好,随访6个月~5年无异常。结论(1)儿童安装永久性心脏起搏器要严格掌握适应证,尽量采用生理性起搏;(2)心外膜手术创伤大,术后并发症少,适合超声心动图显示锁骨下静脉内径小于5 mm的患儿;(3)心内膜植入时要注意儿童的心脏结构和生长发育特点。

睾丸鞘膜瓣在尿道修复中的应用

目的探讨睾丸鞘膜瓣覆盖技术在尿道畸形和尿道瘘修复中的效果。方法2002年起对38例尿道下裂手术和术后尿道瘘,采用睾丸鞘膜下组织蒂鞘膜瓣覆盖修复。结果术后随访半年至1年,除1例尿道上裂术后瘘修复后再次发生尿道瘘外,其余均获成功,未再出现尿道瘘或尿道狭窄,阴茎外观满意,勃起正常。结论采用该方法可有效防止尿瘘再发生,提高手术成功率且易于获取,对睾丸无不良影响。     

Bone growth patterns in Chinese children and adolescents: a 6-year follow-up study provides evidence for sexual dimorphism and tracking

Summary We prospectively examined bone growth patterns in 894 children aged 6–17 years at the baseline visit, with a 6-year follow-up. Results show bone “tracking” over a six-year interval and sexual dimorphism of bone attained levels and timing of peak bone growth. Our findings underscore childhood and adolescence as critical periods for building bone and developing gender differences. Introduction Bone growth patterns were prospectively examined in 894 Chinese children (496 males), aged 6–17 yrs, from a population-based twin cohort. Whole-body bone area (BA), bone mineral content (BMC), and bone mineral density (BMD) were measured by DEXA at baseline and a 6-yr follow-up. Methods Graphic smoothing plots and generalized estimating equations were used to model bone attained levels, growth, and “tracking”. Results Attained levels of BMC and BA increased curvilinearly with age. Male attained levels were higher than females after age ∼15 yr, but BMD was lower between 13–17 yrs (Tanner stage I to IV). In both genders, peak BMC and BMD growth lagged ∼2 yrs behind peak BA growth, which lagged 2 yrs behind peak height growth. Peak bone growth occurred 1–3 yrs later in males. Over the 6-yr follow-up, all bone measurements “tracked”, but “shifting” across ranks also occurred, and baseline tertile ranking influenced bone growth. Females with early menarche had higher attained levels than females with late menarche at age 12–13 yrs. Conclusion Our findings confirm and expand previous studies on peak bone growth conducted in Caucasian cohorts, particularly sexually dimorphic and maturational effects. The significant “tracking” of bone measurements in this 6-yr follow-up study underscores the importance that osteoporosis prevention should begin in childhood and adolescence.
