春季养猪重防病

一、猪瘟贯彻合理的免疫程序,在常发地区（非安全区）,仔猪可进行超前免疫（出生后肌肉注射卜2头份／头,1-2小时后再喂初乳）,双月龄再进行二次免疫（2头份／头）。安全区可以进行双月龄一次性免疫。如果有的猪场三周龄首免,双月龄应再免疫一次,种母猪春、秋季各免疫一次;后备母猪配种前20天免疫一次;种公猪在做好仔猪阶段免疫后,每年春、秋两季各免疫一次。     

5例肌肉注射引起婴儿臀部肿胀的原因分析及护理

肌肉注射因注射时间短,起效快,故在儿科门诊、急诊中广泛应用.但由于婴儿肌肉尚未完全发育,加上药物的刺激等因素的影响,部分婴幼儿臀部肌肉注射后会出现注射部位周围皮肤的肿胀,有少数婴幼儿甚至可能因反复肌肉注射导致臀肌挛缩[1],这就给临床护理工作提出了新的问题.本文分析了5例患儿肌注后肿胀产生的原因,并采取相应的改进措施,旨在避免同类问题发生.     

他的性病为何越治越重

一天,孙先生宴请客户醉酒后与宾馆小姐发生不洁性交。3天后,孙先生出现包皮和尿道口红肿,流稠脓,伴有尿急、尿频、尿痛。去医院就医。医生给予肌肉注射青霉素80万单位,每天2次。治疗3天后,孙先生尿道流脓消失、排尿刺激症状减轻,但尿道口和包皮红肿现象无好转。医生改用静脉滴注先锋霉素每次5克,每天1次;口服克林霉素,每次2粒,每天3次,局部涂消毒药水。又持续治疗4天,非但无效,而且包皮红肿加重,皮肤破溃流黄水,创面糜烂形成溃疡。经治医师疑诊为梅毒感染,但取血清检查阴性。     

股神经联合臀部坐骨神经阻滞在老年患者小腿手术的运用

随着人口老龄化的程度越来越严重,医院老年手术患者越来越多,对麻醉是个很大的挑战,提高围术期老年患者的安全性必须解决,所以对循环影响小,效果确切的外周区域阻滞越来越受到麻醉界的认同。与传统的腰硬联合麻醉方法相比较,该方法体位不需严格要求,穿刺成功率高,并发症少,对患者全身干扰小,术后镇痛时间长等优点。     

牛皮肤霉菌病的防与治

牛患皮肤霉菌病后．在体表形成钱币大小的痂皮．表面隆起，有白色鳞屑，无被毛或少被毛；牛头、脸、颈、臀部多发生，患牛消瘦、到处蹭痒。其治疗方法为：除去痂皮．用克霉唑软膏涂擦患处。3天后病牛蹭痒次数明显减少。同时．牛舍通风采光，给牛继续涂抹克霉唑。7天后，小的病灶长出新毛，一月后多数痂皮脱落痊愈。     

高聚生配合低剂量化疗治疗晚期恶性肿瘤临床观察

目的：对不适合手术、放疗、常规化疗及高剂量化疗的晚期恶性肿瘤患者，为提高疗效，用低剂量化疗配合高聚生治疗38例患者，试图诱导出适应性反应，对相继应用较大剂量抗肿瘤药物出现的损伤产生抗性，抑制封闭因子，使T细胞发挥抗肿瘤的作用。超级抗原通过生物调节作用减轻化疗对正常组织的损伤，改变宿主和肿瘤之间的关系，达到治疗肿瘤的目的。本法用常量的1／3～1／2，尽可能选用以往未用过的化疗药物，两周后增加剂量。高聚生开始每次400ug每周3次，以后800ug或每日1次400ug。观察到患者可耐受，症状改善34例、存活12个月11例、24个月7例、36个月3例。淋巴结缩小，骨转移出现个别骨质修复，声音嘶哑恢复，高胆固醇，高甘油三酯，高转氨酶均降至正常。     

科学家发现用臀部控制滑翔方向的“跳伞蚂蚁”

这种蚂蚁拥有奇特的“滑翔秘笈”，不同于其它滑翔物种，它并没有特殊的身体附属物来控制下降过程，却可使用后腿和臀部来控制空中下降路线。     

美能治疗湿疹5O例临床疗效观察

目的：为验证美能治疗湿疹的疗效。方法：分两组。第一组50例，直接静脉注射美能注射液40ml／日。连用7日后改为口服美能片，每次3片，每日3次。第二组50例，肌肉注射康体多注射液4mL／日，观察1个月。结果：第一组(治疗组)总有效率78％，第二组(对照组)总有效率56％，两组总有效率差异有显著性意义。结论：美能治疗湿疹疗效良好。     

The dimensional accuracy of preparation of femoral cavity in cementless total hip arthroplasty

Objective: To observe the accuracy of femoral preparation and the position of the cementless prosthesis in femoral cavity, and to compare the results between the computer-assisted surgical group (CASPAR) and the conventional group. Methods: Ten femoral components were implanted either manually or by CASPAR in cadaver femurs. The specimens were cut to 3mm thick slices. Microradiograms of every slice were sent to a computer for analysis with special software (IDL). The gaps and the medullary cavities between component and bone, the direct bone contact area of the implant surface, the gap width and the percentage of gap and bone contact area were measured in every slice. Results: In the proximal implant coated with HA of the CASPAR group, the average percentage of bone contact reached 93.2% (ranging from 87.6% to 99.7%); the average gap percentage was 2.9% (ranging from 0.3% to 7.8%); the maximum gap width was 0.81mm and the average gap width was only 0.20mm. While in the conventional group, the average percentage of bone contact reached 60.1% (ranging from 49.2% to 70.4%); the average gap percentage was 32.8% (ranging from 25.1% to 39.9%); the maximum gap width was 2.97mm and the average gap width was 0.77mm. The average gap around the implant in the CASPAR group was only 9% of that in the manual group; the maximum and average gap widths were only about 26% of those in the manual group. On the other hand, the CASPAR group showed 33% higher bone contact than the manual group. Conclusion: With the use of robotics-assisted system, significant progress can be achieved for femoral preparation in total hip arthroplasty.
