淋巴瘤样肉芽肿与韦格内肉芽肿临床特点的比较

目的 总结淋巴瘤样肉芽肿病(lym phom atoid granulom atosis,LG)与韦格内肉芽肿( egener granulo Wm atosis,W G)的临床特点,从临床上加以鉴别。 方法 回顾性总结我院与北京协和医院 1989 年以来收治的 6 例 LG和20 例 W G 患者的临床资料,并进行比较。 结果 发热、咳嗽及呼吸困难在 LG 中较常见,流涕、鼻衄及关节痛以W G 为多,肺受累以 LG 为多,耳鼻喉、眼及肾病变在 W G 中明显增多,皮肤受损两者相似。W G 患者常有 c-ANCA 阳性及尿沉渣异常。 LG X 线胸片为双侧多发结节,边界不清,多无肺门、纵隔淋巴结肿大; G 则为双侧多发边界清晰W的结节, 易形成空洞, 肺门和纵隔淋巴结可肿大。LG 病理改变为血管中心性淋巴增生性病变, 浸润的细胞主要是小淋巴细胞和不同数量大的不典型淋巴细胞; 而在 W G 中可见坏死性血管炎及大量中性白细胞、浆细胞及少量嗜酸细胞浸润形成的肉芽肿, 部分有多核巨细胞。W G 经治疗后, 多数患者病情缓解; 则疗效不佳。 结论 LG 和 W G 在临 LG床表现、实验室检查、 影像及病理诸方面的差异有利于两者的鉴别诊断。

NEUROTROPIN IMMUNOSTIMULATING ACTION ON IMMUNOCOMPETENT CELLS

Neurotropin (NSP) is an extract isolated from the skin of rabbits inoculated with vaccinia virus. The present study examines the possible action of NSP on the number and function of immunocompe tent cells in mice. The experiment showed that NSP had no effect on both T and B lymphocytes of nor- malimmunized mouse spleen. The degree of plaque forming cell reaction and titre of specific antibody showed no significant differences when the NSP treated group and controls were compared. How- ever, NSP exhibited promotive effect on specific antigen binding cells in the early stage of immune responses. It was also noted that the rosette forming capacity of human T lymphocytes in vitro was restor- ed markedly by NSP. These results suggest that NSP possesses certain immunostimulating activity, particularly on the specific antigen binding cells and human T lymphocytes.     

护理人力资源危机管理

随着人力资源的社会化和资源配置市场化的形成，人才流动成为现实和可能，人才已成为一种商品、一种资源、一种无形资本，如人才一旦另择良木而牺，将会大大削弱医院竞争的优势。为此，我们对部分三级医院中的护理人力资源管理中存在的两大危机即人员流失危机和人员梯队危机（临时聘用护士占护理人员总数的50％左右）进行分析，从重视育才、用才、留才及内部员工的安定就业、维护品质着手，采取了行之有效的措施，取得了显著的效果。     

硬膜外穿刺针外套管在腹腔镜小儿斜疝高位结扎术中的应用

目的探讨硬膜外穿刺针外套管在腹腔镜小儿斜疝疝囊高位结扎中的应用价值。方法2003年4月-2006年5月,我院对230例小儿斜疝手术应用硬膜外穿刺针外套管代替雪橇钩针实施腹腔镜疝内环口荷包高位结扎术。结果230例手术均获得成功,手术时间：单侧161例8-10 min,嵌顿疝39例15-20 min,双侧30例16-20 min;术后未见有阴囊水肿及睾血疼痛及缺血坏死。术后随访2-6个月111例,6-12个月52例,12-24个月37例,24-36个月30例,无复发。结论硬膜外刺针外套管可替代小儿疝囊结扎专用的雪橇钩针,简便,经济,适合在所有基层医院推广。     

微波子宫内膜去除术与子宫切除术治疗异常子宫出血的疗效比较

目的 比较微波子宫内膜去除术(MEA)和子宫切除术(AH)治疗异常子宫出血的疗效.方法 将异常子宫出血80例分为MEA组和AH组各40例,比较两组临床疗效、手术时间、术中出血及手术前后白细胞变化. 结果 MEA和AH治疗异常子宫出血的有效率无显著差异(39/40 vs 40/40,χ2=0.000,P=1.000).MEA手术时间短[(4.8±1.2)min vs(102.5±34.6)min,t=17.848,P=0.000];术中出血少[0 ml vs(138.3±40.6)ml,t=21.544,P=0.000]. 结论 MEA是一种治疗异常子宫出血有效且微创的手术.     

Performance and comparison of the Cockcroft-Gault and simplified Modification of Diet in Renal Disease formulae in estimating glomerular filtration rate in a Chinese Type 2 diabetic population.

AIMS: Our aim was to assess performances of the Cockcroft-Gault and simplified Modification of Diet in Renal Disease (MDRD) formulae in estimating glomerular filtration rate (GFR) in Chinese diabetic populations and their association with vascular risks. METHODS: A total of 1009 patients with Type 2 diabetes were categorized into low estimated GFR groups (GFR < 60 ml/min/1.73 m(2)) and control groups by the two equations. The performances of these formulae were assessed at different stages of kidney function. Carotid artery intima-media thickness (IMT) and the prevalence of diabetic retinopathy or albuminuria were compared among the groups. The ability of these formulae to identify established vascular risk markers using sensitivity, specificity, positive and negative predictive values were also compared. RESULTS: The prevalence of low estimated GFR was 32.7% with the Cockcroft-Gault formula and 5.2% with the MDRD formula, respectively. In low estimated GFR subjects by the MDRD formula, IMT was significantly thicker than those by the Cockcroft-Gault formula (1.2 mm vs. 1.0 mm; P < 0.05), with a higher prevalence of albuminuria (78.4 vs. 52.8%, P < 0.05) and diabetic retinopathy (46.5 vs. 30.5%; P < 0.05). The Cockcroft-Gault formula gave a specificity of 71.7% and a sensitivity of 37.0%, and the MDRD formula gave a specificity of 96.6% and a sensitivity of 7.9% in estimating low GFR relevant for established vascular risks. CONCLUSIONS: These formulae performed differently in Chinese diabetic populations. The simplified MDRD formula is minimally superior to the Cockcroft-Gault formula for its high specificity and positive predictive values in estimating low GFR relevant for vascular risks.     

Analysis on origin and evolution of mumps]

There was a preliminary recognition on mumps during the Qin-Han to Sui-Tang dynasty, laying a foundation for the scholastic development on this topic in later generations. The title of this disease was identified in Song-Jin-Yuan dynasty with gradual deepening on its principle-method-formula-medication system, a great progress of recognition as compared with the previous ages. In the Ming-Qing dynasty, the recognition became even more systematic, with certain breakthrough in the system of principle-method-formula-medication. In modern age, the experiences were inherited and developed to integrate to modern biomedicine, so that the theory and clinical practice become even more perfect.     

慢性丙型肝炎患者α干扰素和α干扰素受体1的检测

目的建立检测外周血单个核细胞α干扰素受体1(IFNAR1)及检测诱导表达α干扰素(IFN-α)的方法,评价慢性丙型肝炎患者外周血单个核细胞(PBMC)细胞免疫功能与α干扰素治疗的关系。方法Poly IC体外刺激正常对照组和慢性丙型肝炎病毒(HCV)感染组患者PBMC,利用病毒保护试验研究干扰素治疗前后患者PBMC表达的干扰素抗病毒生物学活性差异;IFN-α治疗前后,RT-PCR检测慢性丙型肝炎患者不同干扰素应答组患者PBMC IFNAR1表达的变化。结果对照组PBMC分泌的干扰素活性显著高于慢性丙型肝炎患者应答组患者(P<0.001);干扰素应答组患者PBMC分泌的干扰素活性随治疗时间延长而增加,治疗1个月后显著高于无应答组患者PBMC分泌的干扰素活性(P<0.01),后者始终处于低下水平;IFN-α治疗期间干扰素应答组患者PBMC IFNAR1水平从治疗前的高表达而逐渐减少,正常对照和干扰素无应答组患者PBMC IFNAR1的表达始终较低。结论慢性HCV感染患者的细胞免疫功能受损,不能正常表达IFN-α,但应答组患者经干扰素治疗后IFN-α表达能力逐渐恢复;干扰素无应答组患者PBMC IFNAR1表达受到严重抑制;慢性丙型肝炎患者PBMCIFN-α活性检测及IFNAR1检测结果也许可以作为干扰素治疗预后的判断指标。
