100例性病患者心理健康状况调查分析

目的：探讨性病患者的心理健康状况,为临床治疗和护理提供依据。方法：采用症状自评量表（SCL-90）对100例性病患者的心理健康状况进行测验。结果：100例性病患者SCL-90检测的阳性率为51%,阳性样本因子分居前的是敌对、强迫症状、抑郁、人际敏感。结论：性病患者广泛存在的心理问题,在药用治疗的同时应注意心理方面的治疗和疏导。     

广西边远少数民族学生体型及体质量指数3年追踪**

背景: 前期研究表明广西18~22岁少数民族学生体质量偏轻。 目的：拟进一步了解广西2645名少数民族学生体型及体质健康状况，寻找影响的关联因子。 设计、时间及地点：追踪调查，于2004-12/2007-12在广西民族大学完成。 对象：广西民族大学2003/2005三次体质健康测试的全体学生2 645人。男1 337人，女1308人，年龄为18~20岁，共15个民族。 方法：根据2003年教育部、体育总局《学生体质健康标准（试行方案）》和实施方法分为形态指标、技能指标和身体素质指标3大类。对2 645名少数民族身体机能与体质量指数变化的跟踪调查。 主要观察指标：身高、体质量、肺活量、立定跳远、坐位体前屈、体质量指数。 结果：①广西民族大学2003级学生大学3年期间男生身高、体质量增长率比全国同期多2.45%，身体形态发育正处于高峰期，女生成偏瘦型体型，身体形态发育情况总体欠佳。②男女学生在刚入校时肺活量机能较差，远远低于同期全国平均水平。3年后男生肺活量增长率为11.55%、女生肺活量增长率为27.72%，分别高于全国同期肺活量增长率。③坐位体前屈机能高于同期全国平均水平，男生呈逐年上升趋势，同期全国男性呈下降趋势；同期全国乡村女生均呈逐年上升趋势。④立定跳远机能提高较大，3年后增长率为18.15%，明显高于全国同期立定跳远增长率水平的2.61%。女生立定跳远机能总体不如全国同期水平。⑤体质量指数总体与同期全国乡村男女学生体质量指数比较稍低一些(P < 0.01)。 结论：2 645名少数民族学生发育正处于高峰期；肺活量机能不及全国同期平均水平。男女体质量指数分布有所不同，体质量偏轻者女生多于男生，表明学生营养状况总体欠佳。     

Lipid extract from completely sporoderm‐broken germinating Ganoderma sinensis spores elicits potent antitumor immune responses in human macrophages

Ganoderma sinensis has been used widely in Oriental countries for the prevention and treatment of various diseases including cancer. Previous studies have shown that the lipid extract from Ganoderma exhibits direct cytotoxicity against tumor cells. Here, it is reported that the lipid extract from germinating G. sinensis spores, at lower concentrations that have no direct tumoricidal activity, induce potent antitumor immune responses in human monocytes/macrophages. Upon stimulation with the lipid extract, monocytes/macrophages exhibited markedly increased production of proinflammatory cytokines and surface expression of costimulatory molecules. Conditioned medium from stimulated cells effectively suppressed the growth of tumor cells. Apparently, the lipid extract triggered macrophage activation via a mechanism different from that associated with LPS. Moreover, it was observed that the lipid extract could partially re‐establish the antitumor activity of the immunosuppressive tumor‐associated macrophages. These results indicated that in addition to its direct tumoricidal activity, the lipid extract from G. sinensis spores could exert antitumor activity by stimulating the activation of human monocytes/macrophages.

心脾综合征的多普勒超声心动图诊断

目的:探讨多普勒超声心动图对心脾综合征的诊断价值,分析其心脏伴随畸形漏诊及误诊原因,提高对心脾综合征诊断的准确率。方法:本文总结了221例心脾综合征患儿的超声检测结果,并与其心血管造影或磁共振检查结果进行对照。结果:超声心动图诊断为心脾综合征与心导管或磁共振结论符合者199例(占90.0%),诊断不符合者22例(占10.0%)。结论:多普勒超声心动图可以较准确地诊断心脾综合征,但对其心脏伴随畸形检出的准确率尚待进一步提高。     

体外循环期间血浆环核苷酸变化的临床研究

本文对14例体外循环下心内直视手术病人采用放免法,于不同时段测定体外循环转流期间血浆的环核苷酸cAMP 和cGMP 变化。结果表明,在体外循环期间,cAMP和cGMP 浓度进行性上升,转流结束时达到最高峰,随着自身循环的恢复,cAMP 和cGNP浓度逐渐下降,术后次日恢复到术前水平;而cAMP/cGMP 比值在体外循环期间无明显变化。文中讨论了cAMP 和cGMP 变化的机制和临床意义。     

Detection of glaucomatous damage using multifocal ERG

The first‐order kernel analysis in multifocal electroretinogram (mfERG) using low contrast stimulation is suggested as a way to detect the inner retinal responses in animal studies. In this case report, this protocol is applied to human patients with glaucoma to demonstrate the possibility of using mfERG as a tool to detect glaucomatous damage. Two patients with glaucoma were recruited and had mfERG measurements with the 103‐scaled hexagonal stimulus pattern at low (50 per cent) contrast. Their responses were analysed and compared with those from normal subjects with the mfERG measured under the same condition. In the normal subjects, there were obvious oscillatory components on the ascending and descending limbs of the first‐order kernel response to 50 per cent contrast. In the glaucomatous patients, the oscillatory component on the descending limb was obviously diminished. In addition, this component was significantly diminished in the quadrant with a glaucomatous visual field defect. This suggests that the low‐contrast stimulation condition in mERG measurement may provide a good way to detect glaucomatous damage and this may help in clinical diagnosis of glaucoma.
