CLINICAL REPORT ON THE TREATMENT OF 806 CASES OF STIFF NECK WITH TUINA (CHINESE MASSAGE)

The author treated 806 cases of acute stiff neck with Tuina. Among all the treated pa-tients,804 were cured with one session, the cure rate was 99. 75 %; and the other 2 were improved,the improvement rate was 0. 25%. So the total effective rate was 100%.     

Neuroretinal rim measurement error using PC-based stereo software

The neuroretinal rims of a set of glaucoma patients were measured using digitized stereo photographs, to determine the reproducibility of computerized stereo measurements of the neuroretinal rim. Each rim was measured five times at 18 locations, with measurement error (ME) defined as the mean of standard deviations of each set of measurements. The following ME were determined: (i) inter-sessional variability (n = 27 right and 24 left eyes, at t1 and t2); (ii) inter-assessor variability (n = 9, 2 assessors); and (iii) variability after colour adjustment algorithms were applied (n = 15). The results were as follows: (i) inter-sessional variability was 3.41+/-1.08 for t1 and 3.22+/-0.84 for t2; (ii) there was a significant difference between the two assessors, although the ME was still low; and (iii) there was no significant differences between the ME of unadjusted and adjusted images. With a measurement error of up to 11% of rim width, these results show that lowcost rim measurements can be made using PC-based software.     

A psychosocial follow-up study of deaf preschool children using cochlear implants

The aim of the study was to explore patterns of communication between 22 children with cochlear implants (CI) and their parents, teachers and peers in natural interactions over a 2-year period. The children, between 2 and 5 years old when implanted, had used the implant between 1 and 3.5 years at the end of the study. Analyses of videorecorded interactions showed that meaningful oral communication was more easily obtained in the home setting than in the preschool setting. Patterns of communication between parent-child, content and complexity of dialogues, quality of peer interactions, communicative styles of adults, and the use of sign language in communication turned out to be important factors when explaining the result of the CI on the individual child's development. The children with the best oral skills were also good signers.     

CT of small bowel obstruction secondary to a cocaine-filled condom

Drug smuggling is prevalent in our society. It is now frequently seen in the emergency room as an acute life-threatening emergency. The following case describes one such patient with an emphasis on the CT findings in these cases. Electronic Publication     

应激状态下危重症患儿胰岛功能及胰岛素抵抗指数的变化

目的探讨危重症患儿应激状态下糖代谢与胰岛功能及胰岛素抵抗指数(IR)的关系。方法应用放射免疫法对危重症(30例)和正常对照组(30例)测空腹血糖(FBG)、空腹胰岛素(FINS)、空腹C肽(FCP)、胰岛素敏感性指数(ISI)、IR和空腹细胞功能指数(FBCI)等参数,并进行统计学处理。结果观察组FBG与对照组比较有显著差异(P<0.001),观察组FINS 显著高于对照组(P<0.001),观察组FCP与对照组比较有显著差异(P<0.001);观察组FBCI与对照组比较无明显差异(P> 0.05);对照组ISI明显高于观察组(P<0.01);观察组IR明显高于对照组(P<0.01)。结论危重症患儿出现胰岛素抵抗,对胰岛素敏感性减低,IR增加,是危重患儿糖代谢紊乱的重要原因。     

儿童外伤性股骨头缺血坏死的X线诊断

目的:探讨儿童股骨头缺血坏死(ANFH)的早期X线征象。尽早诊治,避免残疾。方法:回顾分析43例患儿45个股骨头的X线特征及各期的X线表现。结果:根据病变发展过程与X线平片所见,将ANFH分为4期,I期9个股骨头(9/45)占20%,期18个股骨头(18/45)占40%,期12个股骨头(12/45)占27%,期6个股骨头(6/45)占13%。经与手术及病理对照基本一致。结论:1“新月征”是ANFH早期特征性X线表现,对本病早期诊断具有诊断意义。2ANFH的X线病理分期,对临床选择治疗方案和预后有指导意义。3平片X线检查对高危人群的早期普查和随防有重要价值。     

胆石性肠梗阻的分析和诊治

目的 :分析胆石性肠梗阻的临床表现 ,探讨其诊断和治疗方法。方法 :对我院 1 980～ 2 0 0 0年收治的 1 8例胆石性肠梗阻患者资料作回顾性分析 ,其中 1 6例行肠壁切开取石术 ,同时行胆肠内瘘修补 5例、小肠部分切除 2例 ;2例以中药大承气汤治愈。结果 :本组 1 8例胆石性肠梗阻患者均治愈 ,无死亡。 1 2例随访 2～ 3年均无复发和出现胆系症状。结论 :胆石性肠梗阻以高龄女性好发、病程较长、常有中间腹痛缓解期的病史是其临床特点。术前诊断较困难 ,腹部平片、 B超有助于诊断 ,CT有较为特殊的表现 (Rigler三联征 )。解除结石梗阻是中西医结合治疗的主要目的。手术应以安全有效的肠壁切开取石术为主     

Endogenous cannabinoid, 2-arachidonoylglycerol, attenuates naloxone-precipitated withdrawal signs in morphine-dependent mice

In the present study, we examined the effects of endogenous ligand 2-arachidonoylglycerol (2-AG) on naloxone-precipitated withdrawal in morphine-dependent mice, in comparison with that of two cannabinoid agonists, an ingredient of Cannabis sativa Delta(8)-tetrahydrocannabinol (Delta(8)-THC) and the synthetic cannabinoid CB1 receptor agonist HU-210. 2-AG at a dose of 10 microg per mouse (i.c.v.) significantly inhibited both jumping and forepaw tremor as signs of withdrawal following naloxone challenge in morphine-dependent mice. Furthermore, both Delta(8)-THC and HU-210 significantly attenuated these symptoms of withdrawal in morphine-dependent mice. Therefore, it is suggested that inactivation of the endogenous cannabinoid system is related to the induction of withdrawal syndrome in morphine-dependent mice. Moreover, hyperlocomotor activity in morphine-dependent mice was markedly increased by Delta(8)-THC 10 mg/kg, which had no effect in naive mice. This finding suggested that in morphine dependence, upregulation of cannabinoid CB1 receptors occurred. Non-psychoactive CB1 receptor agonists or accelerators of endocannabinoid synthesis may be potential as therapeutic drugs for opiate withdrawal symptoms.     

The egg-shell sign: a possible indicator of raised intrarenal pressure

 Prenatal diagnosis of pelvicalyceal dilatation has produced clinical material that we are continually reinterpreting with the help of improving ultrasound equipment. However, the ability to predict the outcome for any one patient with marked dilatation remains poor. We describe a new sign that may help identify those fetuses who have high intrarenal pressure and therefore justify more aggressive management, while obviating the need for intervention for those in whom it is not present. The egg-shell sign consists of a thin crescent of increased echogenicity over a distended calyx and, in this case, was documented to be associated with other features of raised intrarenal pressure.
