Methods A nested RT-PCR was used for detecting one fragment of SARS-CoV RNA in oropharyngeal swabs from 3 SARS probable patients ,4 SARS suspect patients and other 27 patients with fever in Hangzhou, and the nested RT-PCR product from one SARS probable patient was sequenced.Meanwhile in these 3 SARS probable patients, other three RT-PCR methods, including a hemi -nested RT-PCR targeted for another fragment of SARS-CoV RNA, a real-time RT -PCR and a modified nested real-time RT-PCR, were employed to detect SARS-Co V RNA.Results Two positives were found in the 3 SARS pro bable patients, and none positive in 4 SARS suspect patients and other 27 patien ts with fever, using the nested RT-PCR.

方法对2003年杭州市3例严重急性呼吸综合征临床确诊患者、4例疑似和27名医学观察者的咽拭子标本用巢式实时RT-PCR检测SARS-CoV核酸，对阳性扩增产物进行核酸序列测定，同时对3例患者的标本应用半巢式RT-PCR检测另一位点SARS-CoV核酸片段，并应用常规实时RT-PCR技术及改良实时RT-PCR技术进行检测。

Methods: We analyzed nucleic acid sequence of the SARS-CoV and SARS-like CoV which were obtained from the GeneBank. The evolutionary trees of SARS-CoV and SARS-like CoV were made up by using the Brede virus as outgroup, and analyzed variation in single nucleotide sequence.

对GenBank登录的SARS冠状病毒和SARS样冠状病毒(SARS-like CoV)核酸序列进行了分析，以Breda病毒为外组，构建了SARS冠状病毒和SARS样冠状病毒系统进化树，并进行单核苷酸变异分析。

Nucleoprotein is also a major immunogenetic antigen for SARS; however, several tests have shown that N protein had the reactivity with other coronavirus positive sera. It is therefore an advantage of S protein as recombinant target antigen for SARS serum diagnosis compared with recombinant N protein. Moreover, S protein has been shown to be the major antigenic determinant that induces neutralizing antibodies and protective immunity to SARS-CoV, so it is also important in designing SARS genetic engineering vaccine.

SARS-CoV S 蛋白由1255 个氨基酸组成，体外表达如此大的蛋白很困难，而且表达蛋白的可溶性不高；其次，实验已经证实，全长S 蛋白含有大量无关的表位，致使表达的全长S蛋白对SARS 阳性血清的检出率低于S 蛋白片段；另外作为疫苗研究，S 蛋白上大量无关表位作为异体蛋白进入体内，会引发机体的过度免疫反应，这也是SARS-CoV 可能的致病机理之一。

The positive rate of SARS CoV antibody IgG is proved to be low among the pupils in this area, but concessive infection and aggregation of SARS still exist; the level of SARS CoV antibody will gradually decline or even diminish as time goes by.

该地区小学学生SARS-CoV抗体阳性率较低，存在隐性感染及聚集现象，SARS-CoV抗体IgG水平随时间延长会逐渐下降，甚至消火。

Infection control nurse had very high percentage of anxiety and the level of anxiety significantly influenced by religion devoutness, working experience, working nature, infection control license, SARS handling experience, and taking care of SARS patient and participate establishing the SARS Fast Response Center.

感控护理人员在SARS期间有高比例处於高焦虑状态，其焦虑程度会因个人基本属性（宗教信仰虔诚度、工作年资、工作性质、感控师执照、处理过SARS事件经验、收治过SARS病人及成立跨单位SARS工作小组或应变中心）不同而有显著差异。

3Clinical investigation: during the epidemicity of SARS, 21 SARS patients were admitted by Inner Mongolian Hospital between April and May , 2003. as a controlled group who were treated with anti-virus, antibiotic, immunization and allowance of nutrients: and another 21 SARS patients as clinical treatment group who were treated with both Erihemu-8 (3g once, twice a day, taken orally , ten days in all ) and the above medicines.

3临床观察：在SARS 暴发流行期间，对内蒙古自治区医院在2003年4～5月收治的SARS 住院患者选取21例作为临床对照组，给以抗病毒，预防感染，免疫调节，营养支持，对症；另选取21例SARS 住院病人作为治疗组，在上述治疗基础上加用蒙药额日赫木—8，3g/次，2次/日，冲服，疗程10天。

The simulation outcome demonstrates that various control measures after April 20,2003 in Beijing and the public holidays starting from May lst to May 5th have a significant impact on containing the epidemic situation. The most dangerous days, around April 27, when the number of uncontrolled SARS patients in the society reached at its peak, can also be calculated. The SARS infectiousness number newly reported in Beijing has been at a low level since May 20. But simulation experiments describe that it may fluctuate with import of SARS infectiousness from outside Beijing, weakening of quarantine, more social activities, and so on.

同时应用动力学模型，对北京的SARS疫情进行分时间段的模拟与SARS实施控制因素影响分析，结果表明，2003—04—20以后一段时间内实行的各种控制措施，以及5月1日—5月5日的长假对于北京SARS疫情的控制是非常有效的；而4月27日左右北京市社会上未得到有效控制的SARS病人数达到高峰，是最危险的时期。5月20日以后，北京的SARS疫情基本保持在低发的平台期，但是如出现较多的外来SARS病例输入，而内部隔离强度又减弱、社交活动增加等情况下，北京SARS疫情可能会有一定程度的波动与反弹。
