Pathways from first health care seeking to diagnosis: obstacles to tuberculosis care in rural China.

OBJECTIVE: To examine health care seeking pathways for patients with tuberculosis (TB) and barriers related to these pathways in counties under the National TB Control Programme in rural China. METHODS: A cross-sectional study was conducted in two counties of east China in 2004-2005. A total of 557 TB patients were recruited and interviewed by physicians at the time of TB diagnosis. RESULTS: Of 557 participants, 13.3% had presented to a specialised county TB dispensary (CTD) directly after onset of symptoms, 31.4% had first sought care at a village health station and 51.2% had visited a township or county hospital first. The proportion of referral by a first health care provider to a CTD was highest in county level hospitals (73.5%) and lowest in village health stations (21.7%). The most prompt pathway from first health care seeking to TB diagnosis was to visit a CTD directly, with a median provider's delay of only one day. There was an increase in provider's delay when more health facilities were involved. CONCLUSION: To improve direct referral from general health care providers, especially village health care workers, to TB specialists would significantly shorten the delays in TB diagnosis in rural China.     

脊柱复合性损伤的救治风险与早期治疗

目的评估脊柱复合性损伤的特点和救治风险,探讨风险控制与最佳治疗的方法。方法采用AIS、ISS、TRISS及APACHEⅡ等评分方法对273例脊柱复合性损伤患者进行定量评价与救治分类,并依据伤后的损伤分级、参数评定及计量评分等指标进行量化分析和统计处理。结果颈椎合并伤115例,胸椎合并伤141例,胸腰椎合并伤294例,腰骶椎合并伤181例;患者的救治风险和脊椎伤的治疗选择或手术时机与其合并伤的解剖伤势及由此所构成的整体伤情密切相关(P<0.01或<0.05);高风险性伤员往往综合伤势严重,生存概率(Ps)趋低,并发症和死亡率高(P<0.01或<0.05)。结论脊柱脊髓损伤常合并有严重的多发伤,高危伤情不仅可增加其救治风险和脊柱伤的处理难度,且还易于丧失手术最佳时机。分类救治对伤员的风险控制和脊柱伤的专科治疗是有益的。

研究生主观幸福感与人格特征相关研究

目的探讨研究生的主观幸福感与人格的关系。方法采用艾森克人格问卷量表与总体主观幸福感量表（GWB）对200名研究生进行测验。结果（1）在专业、性别、年级、年龄、婚姻状况上及来源上，研究生的主观幸福感不存在显著差异。（2）相关分析表明外向性人格纬度与总体幸福感存在显著的正相关，神经质与总体幸福感存在显著的负相关。稳定外向型和稳定内向型人格的总体幸福感水平最高，其次是不稳定外向型人格，总体幸福感水平最低的是不稳定内向型人格。结论外向性与神经质等人格特征是影响研究生幸福感的重要因素。     

《麦克白》主人公的悲剧心理

《麦克白》在现代莎评中自身几乎转换成了充满原型的心理悲剧，它在女巫、鬼魂、超自然因素及阴暗的色彩等笼罩下充分展示悲剧主人公的潜意识心理及其极力保持心灵内外对统一的平衡的努力；主人公本我狂野的欲望及其在事后的病态心理表现正是他们意识内外失控的心态，犹如进入黑夜的漫长旅程。     

Cytotoxic lipid esters from Peucedanum ledebourielloides

Two cancer cell growth inhibitory esters, 1,2-dipalmitoyl-3-glucosyl glycerol (1) and 1,6-dihydroxy-hexane-bis-palmitoyl ester (2), together with arachidic acid-2-hydroxy-glycerol ester, daucosterol, and oleanolic acid, were isolated from the roots of Peucedanum ledebourielloides (Apiaceae family). The structures were determined by spectroscopic analyses. The esters 1 and 2 displayed significant activity against the SGC-7901, HT-29, and HL-60 cancer cell lines.

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.
