Thorax X-ray check should be done to the thoracic trauma cases within 3 weeks in order to find the delayed hemopneumothorax. Therapy methods include symptomatic treatment and surgical treatment according to the condition of disease.

胸部受创伤后3周内应定期行胸部X线检查，警惕迟发性血气胸的发生，确诊后应根据病情予对症观察治疗或采取胸穿术、胸腔闭式引流术或剖胸术。

METHODS From January 1998 to February 2001, 4 ml of sodium hyaluronate injection was injected into the knee joint of the 134 cases at the end of arthroscope operation, or the 91 cases undergoing open operation of the knee at the time when the drain tube was removed. Five days after operation, the hydrarthrosis was removed and 2 ml of sodium hyaluronate was injected into the knee joint. According to the patient's condition, injection of sodium hyaluronate was performed once a week for several weeks. Clinical evaluation was made by evaluating pain visual analog scale and painless range of movement of the joint at every definite point of time.

1998年 1月～ 2 0 0 1年 2月，对关节镜手术 134例于手术结束时，以及膝关节开放手术 91例于术后 2 4小时拔引流管时，分别在关节腔内注射透明质酸钠 4ml ；术后第 5天抽出关节积液，再注入透明质酸钠注射液 2 ml；每周 1次，连续 5周为一个疗程，根据病情注射1～ 2个疗程，观察各时间点疼痛 VAS评分和达到最大无痛活动度的时间。

METHODS: T-lymphocyte subsets and NK activity were determined by flow cytometry in 78 patients with hypopharyngeal squamous cell carcinoma.

用流式细胞仪对78例喉咽鳞癌患者的外周血进行T淋巴细胞亚群及NK细胞活性的检测。

Patients were consideredpositive when the expression were more than 20% cutoff for ZAP-70 and30% cutoff for CD38 .The CDS+ T cells in the same sample were used asinternal positive control, Isotype control was use for every sample .serumβ2-microglobulin was analyzed by ratenephelometry.

应用四色流式细胞术检测50例B-CLL患者外周血白血病细胞ZAP-70和CD38的表达，以ZAP-70≥20％、CD38≥30％为阳性，以CD5~+的自身T细胞为内在阳性对照，同时作同型对照。

Flow cytometry was used to detect intracellular c-FLIP protein in peripheral T and B lymphocytes, immunohistochemistry to examine the expression of c-FLIP in lesional tissue.

采用流式细胞仪检测30例寻常性银屑病患者和20例正常人对照组外周血T细胞和B细胞内c-FLIP蛋白表达阳性率，采用免疫组化方法检测c-FLIP蛋白在其皮损中的表达。

MethodsThe patients who were treated from 2002 to 2004 in Beijing Friendship Hospital were divided into two groups: asthmatic group and nonasthmatic group.Fresh peripheral blood samples of patients in two groups were tested through the flow cytometry.

方法对2002—2004在北京友谊医院就诊的急性期喘息型病毒性肺炎患儿37例及非喘息型病毒性肺炎患儿32例，采用流式细胞仪对其外周血淋巴细胞亚群进行检测。

Negative pressure drainage is a simple, safe and effective method for high perianal abscess after primary radical surgical procedure.

结论负压吸引球操作简便，安全可靠，是高位肛周脓肿根治术后引流有效的方法之一。

BACKGROUND: With supraglottic airway devices, such as the laryngealtube suction, ProSeal laryngeal mask airway andCobra perilaryngeal airway, oropharyngeal leak pressureor cuff position may vary according to changes in the positionof the head and neck.

背景：在使用声门上气道装置时，例如：喉管吸引，胃管引流型喉罩，Cobra喉周通气道，口咽漏气压力和套囊位置会随着头颈位置的变化而变化。

Bronchial carcinoid tumors may be manifested by severe and prolonged flushing episodes, facial and periorbital edema, excessive lacrimation, salivation, tachycardia, and hypotension.

支气管类癌综合征可以表现为严重的长时间的潮红、面部和眶周水肿、多泪、流涎、心动过速或低血压。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
