Clinical observations on 278 cases of cervical spondylopathy treated with electroacupuncture and massotherapy.

From Dec. 1990 to Dec. 1993, 278 cases of cervical spondylopathy were treated with electroacupuncture and massotherapy. The cure rate was 82.7%; but in the control group, it was only 61%, indicating that electroacupuncture may enhance the cure rate (P < 0.05). Of the 278 cases treated by three to five sessions, the pain and numbness disappeared in about 96% of the patients.     

Cardiokymograph system with a capacitance transducer and its preliminary application in the measurement of heart wall movement

A novel cardiokymograph system is introduced. The new system features a capacitance transducer with increased sensitivity and can be used in multichannel measurements. The novelty of this technique is the injection of a current into the patient coupled with the use of a capacitive displacement transducer and the possibility of multichannel monitoring. It provides for the possibility of removing breath noise when some signal processing technique, such as adaptive filtering, is used. Further investigation is needed to demonstrate clinical significance and pathologies.     

双氯芬酸钠滴眼液稳定性研究

采用高效液相色谱法测定双氯芬酸钠滴眼液的含量，方法简便，准确，能将药与杂质峰完全分离。应用化学动力学原理以恒温加试验预测双氯芬酸钠滴眼液稳定性及有效期，室温下有效期ｔ＾２５℃０．９约为２．５７年，与留样观察结果相符。     

LightCycler实时监测PCR定量分析血清HBV DNA

目的 检验LightCycler实时监测PCR（real-time detection PCR,RTD-PCR)对血清中HBV DNA定量检测的灵敏性和可重复性，探讨HBV血清标志物与HBV DNA定量的关系。方法 HBV定量按深圳匹基公司乙肝PCR荧光检测试剂盒使用说明，对乙肝标志物已明确的773例血清中HBV DNA定量结果进行统计分析。结果 实时监测PCR对血清中HBV DNA定量检测的灵敏性高，可检测低至1000拷贝／ml血清；可重复性好，批间误差＜20％；各种标志物类型的血清HBV DNA含量分布情况表明，HBV血清标志物中HBeAg与HBV DNA含量有明显的关系，一般HBeAg阳性血清HBV DNA含量较高，但也有相当一部分例外。结论 LightCycler实时监测PCR对血清中HBV DNA定量检测灵敏性高可重复性好；仅根据HBV血清标志物往往不能确定乙肝患者HBV DNA复制水平的高低，HBV DNA定量检测具有十分重要的临床意义。     

慢性放射性溃疡32例治疗体会

慢性放射性溃疡治疗难度较大，为寻求适当的治疗方案提高疗效，对既往病例进行了回顾。总结了自１９８３年以来，慢性放射性溃疡３２例的治疗经验，对发病原因、部位、病变特点及治疗方法作了分析。３１例治愈、创面Ｉ期愈合２６例，Ⅱ期愈合５例，死亡１例。认为须提高对放射溃疡的重视和认识，针对不同的病变部位，深度及其特点，采取不同的清创方法及相应的修复措施。为改善局部血循环，应以皮瓣或肌皮瓣治疗为首选。     

CT造影剂碘海醇注射液的制备及动物实验

本文报道了非离子型Ｘ－ＣＴ造影剂碘海醇注射液的制备及动物实验结果。磺海醇的最大吸收波长λ＿（ｍａｘ）为２４４ｎｍ。讨论了温度、浓度对磺海醇溶液粘度的影响：粘度随温度的升高而下降，呈负线型相关；粘度随浓度（Ｃ）升高而激剧升高，与浓度的四次方呈线性相关：Ｖ＿（３７℃）＝４７２．５８９［Ｃ］￣４＋１．１２１（ｒ＝０．９９７７）Ｖ＿（３０℃）＝６６３．８１３［Ｃ］￣４＋１．１５２（ｒ＝０．９９９６）Ｖ＿（２０℃）＝１０８２．９５３［Ｃ］￣４＋１．４３３（ｒ＝０．９９８２）使用该注射液进行狗的造影实验，获得了清晰的造影图像。     

Grip and pinch strength among selected adult occupational groups

A survey of 402 normal subjects (203 men, 199 women) was conducted to assist in distinguishing potential differences in norms of hand strength. Norm data had previously been collected from mixed occupational groups, but in the present study it was hypothesised that people involved in heavy manual work on a daily basis might possess greater hand strength than others. The volunteers were adults working in industry and agriculture; they were subdivided into occupational categories. Measurements of grip, key and palmar pinch using the Jamar dynamometer and B and L pinch gauge were collected, using the protocol described by Mathiowetz. Volunteers also rated their individual hand strength job requirements subjectively. Mean values were established with regard to age, sex, dominance, occupational group and subjective rating. Significant differences were found with regard to age and sex but not to dominance; there was no evidence of differences between occupational groups or between subjective rating and individual scoring, i.e. volunteers who perceived their job as requiring a high degree of strength did not achieve higher test measurements than others. A high interrater reliability was demonstrated when comparing these follow-up measurements with the original data. It was concluded that, for clinical and rehabilitative purposes, therapists can interpret assessment of outcome most accurately by comparing patients' results with the existing norm data.
