彩色多普勒血流显像(CDFI)评价胎儿生长发育状况

目的阐明CDFI对评价胎儿宫内状况的可行性。方法200例经普通B超检查的胎儿,按测量各项常规指标的数值分为正常组100例和异常组100例,再分析经CDFI检查,所测定的指标包括胎儿大脑中动脉、肾动脉、胎盘床动脉、脐动脉血流搏动指数(PI)、阻力指数(RI)及脐动脉的收缩与舒张期峰值速率之比(S/D)。对其结果做详细记录,并进行统计学分析。结果正常组100例,经CDFI检查亦正常;胎儿出生时体重在2500g以上,新生儿发育正常。另100例异常组经CDFI检查各项指标中,54例正常,46例异常;胎儿出生时体重均小于2500g,其中54例新生儿虽体重较正常儿偏小,但发育正常;另46例胎儿宫内窘迫,导致导常分娩、新生儿生存率低。结论彩色多普勒血流显像对了解胎儿宫内情况有着重要的作用,是产科检查监护中不可缺少的部分。     

胰岛素使用方法的研究进展

胰岛素治疗是糖尿病治疗的重要内容,也是使糖尿病患者血糖达标的有效方法。严格的血糖控制对糖尿病慢性并发症的预防和延缓发生有重要意义,然而目前各国的糖尿病血糖控制达标率均不足50%。患者甚至包括医生对低血糖的恐惧是启动胰岛素治疗和达到最佳胰岛素治疗的主要障碍之一。     

The effect of ethanol intake on tendon healing: a histological and biomechanical study in a rat model

Introduction  

Ethanol has a suppressive effect on inflammation and the immune system, but the effect of ethanol on tendon healing in vivo has not been studied. The purpose of this study was to investigate the histological and biomechanical effects of ethanol intake on tendon healing in a rat tendon injury model.     

Some new clinical applications of rhinomanometry

Clinical applications of active anterior rhinomanometry of the oscillation type had been carried out for the purposes other than the conventional uses of rhinomanometry. 1. Effect of acupuncture upon the nasal resistance to airflow: Among 8 acupuncture points which were recorded in Chinese traditional medical literatures as effective for improving nasal breathing, Ingxiang point had been proved to possess definite effect of lowering the nasal resistance to air-flow in patients with congestion of nasal mucosa, whereas in other acupuncture points this effect was not certain. 2. The severity of snoring before and after treatment could be determined objectively by the measurement of nasal resistance to air-flow and the breathing pattern of the patient.     

小干扰RNA干扰大鼠神经元Nogo受体mRNA表达的实验研究

目的观察大鼠Nogo受体(NgR)特异性小干扰RNA(small interfering RNA,siRNA)在原代神经元干扰其mRNA表达的效果。方法体外培养大鼠原代皮层和海马细胞,应用阳离子脂质体转染试剂转染4对化学合成的大鼠NgR特异性siRNA,72h后提取细胞总RNA,实时荧光定量RT-PCR检测NgR mRNA表达情况。结果4对siRNA均能够下调靶基因NgR的mRNA表达水平,siNgR199、siNgR562、siNgR772和siNgR964等干扰后,NgR mRNA的表达分别为对照siRNA干扰组的6.5%、62.4%、15.2%和6.86%,与对照siRNA干扰组比较有统计学意义(P<0.05)。结论化学合成的NgR特异性siRNA能够有效的干扰大鼠原代皮层和海马细胞内NgR基因mRNA的表达水平。     

穴位按摩解除妇科腹腔镜术后患者非切口疼痛效果观察

目的 探讨穴位按摩解除妇科腹腔镜术后患者与气腹相关的非切口疼痛的效果.方法 随机将138例行腹腔镜妇科手术患者分为按摩组和常规组,各69例.按摩组术后采用穴位按摩,即双手掌侧王于患者双肩部,用拇指带动鱼际肌压住患者的阿是穴,呈旋转式按摩,持续5～30s,间歇3s,连续15～20min,同时配以腹腔镜康复操.常规组行常规术后护理.观察两组术后肩痛、上腹膈肌疼痛及切口疼痛情况.结果 按摩组患者术后24h、72h肩痛程度,术后24h、48h上腹膈肌疼痛程度,术后7～24h切口疼痛程度显著轻于常规组(均P＜0.05).结论 穴位按摩可显著缓解妇科腹腔镜术后非切口疼痛,安全易行.     

竹荪深层发酵菌丝体对小鼠免疫功能的影响及其抗肿瘤作用

过对食药用真菌──竹荪深层发酵菌丝体提取液对小鼠免疫功能及S－180肿瘤细胞的作用观察，表明其发酵菌丝体可明显提高小鼠腹腔巨噬细胞的吞噬功能（P＜0．01），并显著增加免疫器官的重量（P＜0．05）；对小鼠S－180肿瘤的抑瘤率为40．63％。
