活血消银片对银屑病患者皮损中微血管密度的影响

目的观察活血消银片对血瘀型银屑病患者皮损中微血管密度的影响。方法将40例患者随机分为两组。治疗组20例口服活血消银片,对照组20例口服消银片,疗程8周,观察两组患者治疗前后皮损中微血管密度的改变,并与正常组对照。结果活血消银片与消银片对血瘀型银屑病人皮损中微血管密度改善的程度差异有统计学意义(P﹤0.01),但患者治疗后与正常组比较差异仍有统计学意义(P﹤0.05)。结论活血消银片可明显改善银屑病患者皮损中微血管密度,但仍未完全恢复正常,这可能与银屑病的复发有密切的关系。     

盆炎丸治疗多重耐药解脲支原体感染的临床观察

目的观察盆炎丸治疗多重耐药支原体感染的临床疗效。方法将60例多重耐药支原体感染患者随机分为2组,治疗组30例口服盆炎丸,对照组30例口服强力霉素,14 d为1个疗程,两组均连续治疗3个疗程,观察2组治疗前后临床证候积分,判断其临床疗效。结果治疗组综合疗效总有效率为83.3%,对照组总有效率为63.3%,两组比较,差异无统计学意义(P>0.05)。在中医证候改善方面,治疗组明显优于对照组(P<0.01)。结论在综合疗效方面,盆炎丸治疗多重耐药支原体感染疗效与强力霉素相当,但在中医证候改善方面,盆炎丸有明显优势,值得临床推广。     

针刺辨证治疗功能性消化不良的临床观察

目的观察针刺辨证治疗功能性消化不良(FD)的临床疗效。方法应用随机数字表将88例研究对象分为治疗组44例、对照组44例。治疗组根据患者辨证分型的不同,分别施以相应的针刺方案治疗;对照组则不辨证统一采用单纯针刺方案治疗。观察患者治疗前后证候积分及疗效指数、SF-36评分、尼群消化不良指数(NDI)以及血浆胃动素(MTL)的变化。结果治疗组脱失1例,总有效率93.02%;对照组脱失2例,总有效率76.19%;两组差异有统计学意义(P<0.05)。治疗完成和1月后随访时,两组相对治疗前症状指数(NDSI)显著降低,生活质量指数(NDLQI)、健康相关生活质量评分(SF-36)均显著增加(P<0.05);与同期比较治疗组NDSI明显低于对照组,NDLQI、SF-36明显高于对照组(P<0.05)。结论对FD患者进行辨证针刺和不辨证针刺都是有效的治疗手段,但是辨证针刺组的总有效率及近远期的疗效均明显优于对照组。     

祛风化痰针刺法改善假性球麻痹吞咽功能障碍的多中心临床观察

目的系统观察祛风化痰针刺法改善假性球麻痹患者吞咽功能障碍的作用。方法将240例确诊为风痰型假性球麻痹的患者随机分为治疗组和对照组,每组各120例,分别给予祛风化痰针刺法和模拟针刺法治疗,取穴风池(双)、完骨(双)、廉泉、丰隆(双)。每天上、下午各针刺1次,连续6 d为1疗程,疗程间休息1 d,治疗4个疗程。采用洼田饮水试验方法于治疗前、治疗2、4个疗程后进行吞咽功能级别评定,4个疗程后进行疗效评定和比较。结果第2个疗程结束后两组患者的吞咽功能评级与治疗前比较有较显著的提高,差异有统计学意义(P<0.01),治疗组优于对照组(P<0.05);与治疗前比较,第4疗程结束后吞咽功能评级进一步显著提高,差异有统计学意义(P<0.01),治疗组较对照组更优,差异有统计学意义(P<0.01);治疗组的治愈率、显效率和总有效率均显著高于对照组,差异有统计学意义(P<0.01)。结论祛风化痰针刺法改善假性球麻痹患者吞咽功能有肯定、持续且显著的作用,有较大的临床应用价值。     

Herd and sow-related risk factors for mortality in sows in group-housed systems

Mortality of sows is a major problem for pig production worldwide. In this study, we used hierarchical multivariable logistic analyses to investigate different risk factors for mortality at the sow and herd level in herds with group-housed pregnant sows. Data included 3652 pregnant and 1266 lactating sows from 34 sow herds. A clinical examination for 16 clinical signs was carried out for each sow, and information about 16 herd related factors was obtained by interviews. Farm records were used to obtain information about whether or not sows died suddenly or were euthanized within 3 months after the clinical examination. Factors increasing the risk of sow mortality in the gestation unit were solid pen floors (OR = 1.87), presence of vulva bites (OR = 1.73) and unwillingness to stand when approached (OR = 1.62). Factors increasing the risk of sow mortality in the lactation unit were pale vulva color (OR = 12.69), body leanness (OR = 4.11), and presence of shoulder ulcers (OR = 2.89). The estimated between herd variation was small. Thus, the findings for the sow level variables may be generally applicable for sows in herds with group housed systems.     

Retrospective study of neurological signs and management of seven English horses with temporohyoid osteoarthropathy

This retrospective study summarises the case details, presenting signs, management and outcome in cases of temporohyoid osteoarthropathy (THO) and describes the findings of diagnostic imaging modalities. The condition appears to be relatively rare in Europe and the objective of this study is to make clinicians aware that THO can have a range of various neurological and clinical presentations. The records of 2 referral equine practices in England were reviewed and 7 horses with THO diagnosed on guttural pouch endoscopy indentified. The clinical and neurological signs, diagnostic procedures, treatment and outcomes were reviewed. Although small, this group is the largest case series of THO from Europe. One horse was a yearling, whereas THO is generally considered usually to affect middle aged and older horses. Computed tomography was used to confirm the diagnosis and demonstrated stylohyoid bone fractures in 2 cases while there was mild increased radionuclide uptake in one of 2 cases undergoing nuclear scintigraphy. Treatment is still controversial, although ceratohyoidectomy led to complete resolution of signs in 2 of 5 cases thus treated and improvement in the other 3. One horse with mild signs treated with antimicrobials and nonsteroidal anti‐inflammatory drugs made a full recovery while another, presented with head shaking and managed with a phased exercise programme, improved but did not resolve completely.     

禽流感防制进展

禽流感（Avian influenza,AI）是由A型流感病毒所引起的禽类的一种传染病。能引起禽类呼吸系统到严重全身败血症等多种症状的烈性传染病。禽类感染后病死率很高,但对野生禽类多为不显性感染。自从1997年香港发生禽流感病毒H5N1亚型首次突破种属屏障感染人类并引起死亡以来,世界各国纷纷报道各种人禽流感病例的发生,人禽流感的关注程度也达到了前所未有的高度。近几年全球共有三大洲的19个国家和地区发生禽流感疫情。一些地区的疫情呈现蔓延的趋势,并且出现了人感染禽流感病毒的病例。禽流感不仅对养殖业造成重大损失,更对人类健康造成严重威胁。本文全面地介绍了禽流感的病原、流行病学、临床症状、病理变化、诊断和防制。
