剖宫产术后疼痛调查

目的寻找剖宫产患者术后不同时间疼痛程度的变化,为临床上准确及时采取镇痛措施提供依据.方法随机抽样100例接受连续硬膜外麻醉下行子宫下段剖宫产的患者,通过制定调查问卷,根据视觉模拟评分法(VAS)调查患者安静,咳嗽和活动时切口疼痛及其恶心、镇静程度,分别在术前、术毕、术后第4、8、12h及此后每12h调查一次,直至术后第144h.结果术后疼痛高峰期在安静时为术后4～24h(VAS值=5.16±0.35),咳动时为术后4～36h(VAS值=6.25±0.56)分别与各自术后整个过程VAS均值(2.13±0.56、3.45±0.28)比较有显著性差异(P＜0.01),二种状况疼痛高峰期无显著性差异(P＞0.05),咳动时高峰期显著延长.术前宫缩痛(VAS值＜4)与(VAS值≥4)两类患者的术后安静时疼痛有显著性差异(P＞0.01).在咳动时,无显著性差异(P＞0.05);疼痛与焦虑、文化程度呈正相关,与术后肠功能恢复呈负相关.结论术后4～36h为剖宫产术后疼痛的高峰期,尤其术前宫缩痛VAS＜4的患者,在术后更引起注意,并可及时采取合理镇痛措施.     

Lead toxicity as a result of herbal medication

Awareness about the toxic effects of non-essential metals is still lacking in developing countries. Lead is one among them, which ranks second in the Agency for Toxic Substances and Disease Registry’ s top 20 lists of toxic metals. Some of the herbal medicines prepared from certain roots and leaves are known to contain this toxic metal at alarming levels. We have a case of a person who suffered from the toxic effects of lead such as vomiting and colicky abdominal pain after consuming a herbal remedy for Jaundice treatment. This went unrecognized initially because of the presence of multiple problems like Malaria and Renal calculi. Lead poisoning as causative factor for anemia, vomiting and colic were confirmed only when blood lead concentration was estimated. A combination of chelation therapy and nutritional supplementation was found to be useful in reducing the body lead burden.     

论“无痛德育”

传统的学校德育正受到后现代道德的冲击,新的重视主体幸福和享乐的道德文化要求学校德育进行相应的调适。无痛德育充分尊重学生作为道德实践主体的自主权利,提倡不损及他人的宽容,鼓励并引导学生在消费、娱乐和享受中追求个体的幸福和快乐,在现实的生活中自然获得道德成长。     

“三桥运动疗法”治疗非特异性下腰痛的临床疗效观察

目的：：观察和评价“三桥运动疗法”治疗非特异性下腰痛的临床疗效。方法：选择成都体育学院附属体育医院2013年10月-2015年3月非特异性下腰痛患者60例,采用“三桥运动疗法”,观测治疗前、治疗后一月及三月的总腰椎前突角,骶骨倾斜角,视觉模拟评分法( VAS),功能障碍指数(ODI),健康调查简表(SF-36)评分变化,对治疗前后疗效进行评估。结果：所有患者均获得随访,“三桥运动疗法”治疗非特异性下腰痛治疗前与治疗后一月,治疗后一月与治疗后三月后相比较两组在总腰椎前凸角差,骶骨倾斜角,VAS,ODI上其差异均有统计学意义( P<0.05)。结论：“三桥运动疗法”治疗非特异性下腰痛临床疗效良好。

The effect of knee angle on the external validity of isometric measures of lower body neuromuscular function

The aim of this study was to evaluate the effect of varying knee angle (120° and 90°) on the external validity of an isometric leg press test with reference to vertical jump performance. Isometric peak force (PF 120 and PF 90 ), rate of force development (RFD 120 and RFD 90 ), and maximum height reached with a squat jump and counter-movement jump were measured in 14 males. Although RFD 120 was significantly correlated with squat jump and counter-movement jump performance ( r = 0.71 and 0.69), and the correlations with PF 120 approached statistical significance ( r = 0.53 and 0.50), neither PF 90 nor RFD 90 was significantly related to vertical jump performance. Furthermore, although both RFD 120 and PF 120 were significantly different between the best five and the worst five jumpers, RFD 90 and PF 90 did not differentiate between individuals' vertical jump performance. We conclude that the choice of joint angle affects the external validity of isometric strength testing. Based on our results, we recommend accurate control of biomechanical specificity and assessment at different angles to find the position at which isometric strength testing is most comfortable.     

Effect of tramadol on immune responses and nociceptive thresholds in a rat model of incisional pain

Objective: To evaluate the effects oftramadol on the proinflammatory responses in a rat model of incisional pain by investigating its effects on nociceptive thresholds and serum interleukin-6 (IL-6) and IL-2 levels. Methods: Forty-two male Sprague-Dawley (SD) rats scheduled for plantar incision were randomly divided into 7 groups (n=6 in each group). Rats in Group 1 receiving general anesthesia with no incision were served as control; At 30 min before skin incision, Groups 2～5 were given 5 ml normal saline or 1, 10, and 20 mg/kg tramadol, respectively, intraperitoneally (i.p.); Group 6 received 10 mg/kg tramadol after operation; Group 7 received 10 mg/kg tramadol before incision, followed by 200 μg/kg naloxone after operation. Mechanical allodynia was measured by electronic von Frey filament to evaluate the nociceptive thresholds 1 h before incision, and 1 h and 2 h after operation. Serum IL-6 and IL-2 levels were measured by enzyme-linked immunosorbent assay (ELISA) 2 h after operation. Results: Mechanical thresholds decreased significantly and serum IL-6 level increased significantly after operation in Group 2 compared with control (P＜0.01), and these changes were reversed respectively by tramadol in a dose-dependent manner (P＜0.05 and P＜0.01, respectively). IL-2 level remained unchanged after operation in Group 2, but decreased in Group 3 (P＜0.05), then gradually returned to the normal level in Groups 4 and 5. The intraperitoneally injected tramadol (10 and 20 mg/kg) produced a potent and dose-dependent antinocicptive effect on the lesioned paw. The antinocicptive effects of tramadol were partially an-tagonized by naloxone (200 μg/kg), suggesting an additional non-opioid mechanism. Conclusion: The results suggest that tramadol could be a good choice for the treatment of pain under the conditions that immunosuppression may be particularly contraindicated.
