目的探讨肺结核与肺癌并存的临床特点、诊断及手术治疗方法。方法对25例肺结核并存肺癌患者的临床和实验室资料进行综合分析。结果患者多为老年，多有肺结核病史，有咳嗽、咯血、胸痛等表现。肺癌漏诊率高，手术治疗效果好。结论肺结核并存肺癌时，易发生漏诊，有条件时应手术治疗。     

固定剂量复合剂治疗肺结核患者依从性调查与分析

Objective To survey and analyse the treatment compliance of fixed-dose combination （FDC）,so as to provide evidences for expending use FDC nationwide. Methods Nine hundred and sixty-six primary smear positive pulmonary tuberculosis cases registered in 17 counties TB institutions from 4 provinces were randomly divid- ed into experiment and control groups. Compared compliance difference with uniform questionnaires, and analysed compliance changes with time throughout the treatment. Results Nine hundred and sixty-one cases were surveyed at the beginning, 899（93.5% ）preferred receiving treatment. There was significant difference on the percentage who prefer had drugs per day between experiment（86.8% ）and control group（42.1% ）（ P 〈 0.01 ）.At the end of intensive phase, 261（28.3 % ）cases perceived difficulty with the treatment ;213 （23.1% ）cases thought that were the doctors who lead to the insist of treatment.At the end of treatment,only 138 cases（15.5% ）thought that were the doctom who lead to the insist of treatment. Conclusion The compliance of FDC was better than control group. It might increase the compliance when decreasing the number of tablets and should expend used on TB control. The ef- fect of TB doctors decreased through the treatment. More intention should be paid in intense phase.     

结核分枝杆菌Mtb8.4基因疫苗与人白细胞介素12表达质粒联合免疫的细胞免疫应答观察

目的 观察结核分枝杆菌Mtb8.4基因疫苗与人白细胞介素12(hIL-12)联合免疫小鼠所诱导的细胞免疫应答.方法 15只C57BL/6N小鼠随机分为Mtb8.4基因疫苗 hIL-12质粒组(联合免疫组)、Mtb8.4基因疫苗组、卡介苗(BCG)组、空载体组和PBS组,基因疫苗、空载体和PBS经肌内注射法免疫各组小鼠,每隔3周免疫1次,共免疫3次,BCG组经尾部皮下注射1×106 CFU BCG免疫1次.ELISA法检测小鼠脾细胞培养上清中细胞因子水平;乳酸脱氢酶(LDH)释放法检测免疫小鼠特异性细胞毒性T淋巴细胞(CTL)杀伤活性.结果 联合免疫组能诱导较强的抗原特异性Th1型细胞免疫应答,免疫小鼠脾细胞培养上清液IFN-γ和IL-2水平(分别为1 493.340±8.128pg/ml、747.489±48.676pg/ml)显著高于Mtb8.4基因疫苗组,与BCG组相当,IL-4分泌减少,特异性CTL杀伤活性增强.结论 hIL-12表达质粒能够增强Mtb8.4基因疫苗所诱导的细胞免疫应答.     

RAPD技术用于结核病交叉感染的鉴别

目的：调查RAPD技术用于结核菌株DNA指纹鉴定的效果。方法：采用多重PCR方法对一组2例母女同时发病的肺结核患者和一组2例先后发病的兄妹肺结核患者的病原菌进行了菌种鉴定。采用RAPD技术对它们的基因组DNA进行指纹多态性分析。结果：4株病原菌均为结核分支杆菌。经RAPD分型，其中母女组2菌株的DNA指纹图谱完全相同，兄妹组2菌株的DNA指纹图谱有所不同。证明母女组所染病原菌的同源性很好，很可能为同一感染源，母女之间交叉感染的可能性很大；兄妹组病原菌的同源性较差，为非交叉感染。结论：RAPD技术适用于结核分支杆菌流行病学调查，特别是交叉感染的鉴别。     

脾结核的临床特征

目的 探讨脾结核的临床特点、诊断和治疗。方法 回顾性分析经临床、手术及病理证实的11例脾结核的临床特征。结果 11例患者中，男7例，女4例，平均年龄29岁。6例术后证实，5例经内科保守治疗后证实。多数患者表现为发热、消瘦、血沉增快、贫血、脾肿大，B超发现脾脏肿大11例，其中8例脾内多发占位，3例为孤立性占位；7例行CT检查，6例发现脾脏多发性大小不等的结节状低密度灶，1例为单发类圆形低密度影，边缘不清，增强扫描病灶内部无强化；6例患者伴后腹膜、脾门区等淋巴结肿大，5例患者伴其它脏器结核。结论 不明原因发热、消瘦、血沉增快、贫血、脾肿大为脾结核的主要临床表现，腹部B超和腹部CT能对脾结核作出较准确的判断，脾结核患者经正规治疗可治愈。     

Tuberculosis in children: a 13-year follow up of 1714 patients in a Belgian home care centre

From May 1970 to September 1983, 1714 children with different forms of primary tuberculosis were referred to the paediatric home care centre (Enfants soignés au Foyer, E.S.F.) of the Brussels University Hospital St.-Pierre. They were subdivided in five groups: asymptomatic (33%), symptomatic (28%), dubious tuberculous infections (35%), high-risk contacts (3%) and unestablished diagnosis (1%). They were aged from 10 days to 19 years, and 82% of them were migrants of low socio-economic level. Fifty percent of the symptomatic infections, mainly pulmonary, appeared in children under 3 years of age. An adult source of contamination was identified in 33% of the case (48% of the symptomatic children). Diagnosis was based on tuberculin screening with a 2IU intradermal test. Gastric aspirates yieldedMycobacterium tuberculosis in 15% of our patients, 11% of them showing resistance to one or more tuberculostatic drugs. Treatment was given to 1359 patients with excellent results. Therapy was shortened during the last 2 years of the study from 12 to 6 months for the asymptomatic patients and from 12 to 9 months for the symptomatic infections. Few complications were observed. Tuberculosis remains a serious cause of morbidity particularly in migrant children. Correct diagnosis and treatment of the disease is very important.
