便秘的中医治疗

便秘是一种常见病、多发病,表现为排便间隔延长或排便艰涩不畅。中医治疗将其分为实秘和虚秘。治法上,实者宜通泄,虚者宜润补,应注意审证求因,审因论法。对便秘的中医治疗作一综述。     

脑缺血后抑郁大鼠皮层及海马IP3表达及中药的干预作用

目的：从磷脂酰肌醇（PI）信号传导通路上重要调节因子IP3的角度，探讨脑缺血后抑郁模型磷脂酰肌醇（PI）信号传导通路的变化及中药颐脑解郁方的干预作用。方法：在脑缺血后抑郁模型上，采用AlphaScreen受体竞争机制，观察脑缺血后抑郁大鼠前额叶皮层、海马IP3含量的变化及中药颐脑解郁方的干预作用。结果：脑缺血后抑郁模型大鼠皮层及海马IP3含量明显高于正常组，模型组IP3的含量明显高于治疗组。结论：脑缺血后抑郁模型大鼠脑皮层及海马IR含量增加，中药颐脑解郁方能使之明显下调，提示脑缺血后抑郁IPl含量增加，颐脑解郁方的抗抑郁作用可能与调节受体后PI信号通路有关。     

对30例便秘效果观察

便秘是中老年人的常见病和多发病。本病多由于身体虚弱，大肠运动无力或长期食辛辣口味、肠胃燥热、津液不布或由于气滞不畅、津液不行、肠失传导而致。运用足疗法效果颇佳，希望中老年人能接受这种足按摩治疗便秘的好方法。

Electrophysiological evaluation in 4 patients with diabetic pseudotabes

BACKGROUND: Researches on diabetic nervous system lesion are mainly focus on peripheral nerve and vegetative nerve, so there are few investigations on diabetic pseudotabes. OBJECTIVE: To investigate the electrophysiological examinations on the diagnosis of diabetic pseudotabes. DESIGN: Case study. SETTING: Department of Electrophysiology and Department of Neurology, Zhongshan Hospital Affiliated to Xiamen University. PARTICIPANTS: A total of 4 patients with type 2 diabetes mellitus, including 3 males and 1 female aged from 50 to 72 years, were selected from Department of Neurology, Zhongshan Hospital Affiliated to Xiamen University from March 2002 to February 2005. All accepted subjects met the modified diagnostic criteria of diabetes mellitus, which was set by American Diabetes Mellitus Association (ADA) in 1997. Otherwise, the subjects had typical symptoms and physical signs of spinal posterior funiculus damage. However, patients with spinal cord lesion which was caused by other factors were excluded. All accepted subjects provided the confirmed consent. METHODS: Nicolet NT electromyography (EMG)/evoked potential meter (made in the USA) was used to detect spinal cord conduction velocity (SCCV), somatosensory evoked potential (SEP) of lower limbs, motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of extremities. Determining criteria: Measurements were performed based on the laboratory standards. SCCV, which was less than lower limit of normal value (T2–12: 40–55 m/s, T12–L4: 20–41 m/s, T2–L4: 36–45 m/s), was regarded as abnormal. SEP value of lower limbs: P40, P60 and PF, which were more than standard deviation of normal value (x(—)+2.5), were regarded as the abnormality. Normal value of P40, P60 and PF latencies (x(—)±s) in this study: P40, P60 and PF in males were (37.6±1.9) ms, (59.8±3.9) ms and (7.6±0.9) ms, respectively; meanwhile, those in females were (35.5±1.7) ms, (55.2±2.7) ms and (6.3±0.7) ms, respectively. MNCV and SNCV, which were less than 50 m/s in upper limbs and 40 m/s in lower limbs, were regarded as the abnormality. MAIN OUTCOME MEASURES: Electrophysiological examinations. RESULTS: All 4 patients with type 2 diabetes mellitus were involved in the final analysis. ① SCCV: Among 4 patients, SCCV of three patients was decreased in T2–12, T12–L4 and T2–L4, and that of the other one was decreased in T2–12 and T2–L4; however, SCCV in T12–L4 was normal. There was significant difference as compared with normal value (P < 0.01). ② SEP of lower limbs: SEP values of lower limbs were abnormal in all 4 patients. Among them, P40, P60 and PF latencies of two patients were delayed; P40 of one patient was delayed and PF was not drained out; P40 and P60 of the last one were delayed and PF was normal. ③ MNCV and SNCV: The MNCV and SNCV were normal in one patient and abnormal in three patients. The results demonstrated that MNCV and SNCV of extremities decreased; especially, sensory nerve action potential (SNAP) of both lower extremities of one patient were not drained out. CONCLUSION: Detections of SCCV, SEP of lower limbs, MNCV and SNCV of extremities are helpful to investigate whether peripheral nerve and deep sensory passage are damaged or not and determine whether deep sensory damage is caused by peripheral nerve and spinal posterior funiculus.

川芎嗪对哮喘大鼠气道壁胶原沉积和转化生长因子-β1表达的影响

目的 观察川芎嗪对哮喘大鼠气道壁胶原沉积和转化生长因子-β1(TGF-β1)表达的影响。方法 SD大鼠40只,随机分为5组,制备大鼠哮喘模型,腹腔注射不同剂量川芎嗪及地塞米松干预。肺组织石蜡切片进行胶原和TGF-β1免疫组织化学染色后计算机图像分析测定其含量。结果模型组气道壁Ⅲ型胶原、TGF-β1含量均显著高于正常对照组(P均<0.001);与模型组比较,不同剂量川芎嗪干预后Ⅲ型胶原、TGF-β1含量均显著降低(P均<0.001) TGF-β1的表达与Ⅲ型胶原的含量呈显著正相关(rs=0.7063 P<0.001);川芎嗪大剂量干预组对TGF-β1表达和Ⅲ型胶原合成的抑制优于小剂量组(P<0.01),大剂量组作用效果接近激素组。结论 川芎嗪可减少气道壁胶原沉积和TGF-β1表达而抑制哮喘气道重建,其部分作用与激素近似。 实用儿科临床杂志,2004,19(12):1028-1029
