目的 探讨CD117在肺基底样细胞鳞状细胞癌(BSCC)与小细胞肺癌(SCLC)中的鉴别诊断作用。方法 免疫组织化学检测CD117在肺BSCC与SCLC中的表达情况,并进行统计学分析,同时文献复习CD117在这两种肿瘤中的表达情况。结果 CD117在SCLC中特异性高表达(阳性率为78%),并且具有高的敏感度、特异度、阳性预测值及阴性预测值(分别为100%、78.2%、68.7%、100%),与文献报道一致(阳性率37%～100%);而在BSCC中未见有CD117的表达,文献未见有CD117在BSCC中表达情况报道。结论 CD117有可能成为鉴别诊断BSCC与SCLC的重要指标之一。但由于本报道例数有限,还需要更大型的研究进一步证明CD117在鉴别诊断二者中的敏感度及特异度。

Objective To investigate the role of CD117 in differentiating basaloid squamous cell carcinoma (BSCC) from small cell carcinoma (SCLC) in lung. Methods Immunohistochemistry staining of CD117 and statistic data were analyzed in BSCC and SCLC, and relevant literature were reviewed. Results CD117 was specifically expressed in high level ( positive rate 78%) in SCLC with high sensitivity, specificity, positive predictive value and negative predictive value (respectively 100%、78.2%、68.7%、100%), which was highly consistent with literature reports (positive rate 37%-100%). CD117 was not detected in BSCC in our report and it was the same as in literatures. Conclusion Although our results showed that it was possible that the expression of CD117 would play an important role in differentiating BSCC from SCLC, due to limited cases in number, more studies are needed to elucidated the sensitivity and specificity.

Methods 50 cases of pulmonary tuberculosis and lung cancer treated in our hospital in 2015~2018 in January were selected as observation group, and 50 cases of simple pulmonary tuberculosis treated in our hospital for the same period were selected as control group. The clinical symptoms and CT imaging findings of the two groups were observed and compared. Results There was no significant difference in clinical symptoms and signs between the two groups (P>0.05), and the proportion of lobular sign and burr nodular nodules in the observation group was higher than that of the control group (P<0.01), and the proportion of parenchymal cavities in the observation group was lower than that of the control group (P<0.01). There was no significant difference between the two groups in the incidence of tumor and streak shadow (P>0.05). Conclusion The CT imaging features of patients with pulmonary tuberculosis and lung cancer are mainly lobular sign, burr like nodules and cavities, which should be qualitatively diagnosed according to these features combined with other tests.

目的 分析慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)合并肺动脉高压(pulmonary hypertention,PH)的危险因素。方法 回顾2014年1月—2015年1月广州医科大学附属第一医院住院患者55例,经心脏彩色多普勒超声测量肺动脉收缩压(PASP),分为:轻度组(36≤PASP＜50 mmHg),中度组(51≤PASP＜70 mmHg)和重度组(PASP≥70 mmHg),分析比较三组临床特征,危险因素采用单因素及多因素Logistic回归分析。结果 年龄(75.3±11.6)岁,PASP为(52.6±15.1)mmHg。单因素分析中-重度PH与年龄、HCT、PaCO₂、PaO₂、D-二聚体有关;多因素Logistic回归分析确定3项危险因素:HCT[比值比(OR)=51.82,95% CI: 2.34～1149.02],RV(OR=4.53,95% CI: 2.83～7.27),及PaCO₂(OR=1.02,95% CI: 1.00～1.03)。结论 呼吸病相关PH多为轻-中度,高水平的HCT、RV直径及PaCO₂提示PH病情较重。

Objective To analyze the clinical risk factors of pulmonary hypertension (PH) associated with chronic obstructive pulmonary disease(COPD). Methods A total of 55 hospitalized patients from 2014 to 2015 were enrolled in the study and were classified into three groups according to pulmonary artery systolic pressure (PASP) with echocardiography as follows: the mild group (36≤PASP＜50 mmHg), the moderate group (51≤PASP＜70 mmHg) and the severe group (PASP≥70 mmHg). Clinical data were recorded and retrospectively analyzed. Results The average age of all patients was (75.3±11.6)years. Echocardiography showed a mean PASP was 52.6±15.1 mmHg. Age, hematocrit (HCT), partial pressure of carbon dioxide (PaCO₂), the oxygen partial pressure (PaO₂), D-dimer and right ventricular (RV) diameter (>20 mm) were associated with moderate-to-severe PH on an univariate regression analysis, while RV (diameter >20 mm)[odds ratio (OR)=4.53, 95% CI: 2.83～7.27], HCT(OR=51.82, 95% CI: 2.34~1149.02) and PaCO₂ (OR=1.02, 95% CI: 1.00-1.03), to these patients, were independent risk factors using the multiple logistic regression analysis. Conclusion PH related to respiratory diseases is mostly mild-to-moderate. Haemoptysis,high levels of RV diameter, HCT and PaCO₂ suggest a serious condition of patients with PH related to chronic respiratory disease.

Objective To evaluate and compare the early diagnosis value of CURB-65,PSI,SMART-COP and APACHEⅡin patients with severe community-acquired pneumonia. Methods This was a prospective study conducted in department of respiratory in Guangzhou First People's Hospital. We included 67 SCAP patients and 33 CAP patients between October of 2011and February of 2014. The lowest scores within 24 hours of CURB-65 score,PSI score,SMART-COP score,APACHE Ⅱ score,respectively,for each patients were recorded. Prediction of SCAP as made in four scoring systems was compared. Results CURB-65 score,PSI score,SMART-COP score,APACHE Ⅱ score were higher in SCAP as compared with that of CAP(CURB-65:3.0±1.1 vs 0.9±0.8,P<0.001;PSI:144.6±36.4 vs 73.9±27.1,P<0.001; SMART-COP:6.5±1.4 vs 1.6±1.0,P<0.001; APACHEⅡ:20.6±5.6 vs 7.9±3.8,P<0.001). ROC curve for CURB-65 score≥ 3 scores,PSI score≥ 130 scores,SMART-COP score≥3 scores and APACHE Ⅱ score ≥ 15 scores in the early diagnosis SCAP were 0.940[95%CI:0.89~0.98,P<0.001],0.933[95%CI:0.88~0.97,P<0.001],0.999[95%CI:0.99~1.0,P<0.001],0.976[95%CI:0.95~0.99,P<0.001]. Sensitivity of four kinds of scoring system was 65.6%,71.6%,100%,88.1%, with specificity of 100%,100%,78.7%,93.9% respectively. Conclusion The specificity of diagnosis was better in the CURB-65 and PSI score,but the sensitivity was low and easy to miss diagnosis. SMART-COP and APACHEⅡscore systems had a better diagnostic value on SCAP.

目的 在原来研究的基础上进一步研究Wnt-1信号通路蛋白-3（WISP-3）在高氧诱导肺上皮细胞凋亡中的作用。方法 通过Western blot检测和免疫组化检测不同肺上皮细胞中WISP-3的蛋白表达量。利用质粒转染和siRNA的方法在Beas-2B细胞中高表达和基因沉默WISP-3,通过细胞活性检测和流式细胞学技术检测高氧刺激后细胞的凋亡情况。结果 与空气对照相比,高氧刺激使肺上皮细胞的WISP-3蛋白表达量下降;WISP-3基因沉默或高表达使高氧诱导的肺上皮细胞凋亡增加或减少。结论 高氧刺激下,肺上皮细胞中WISP-3表达下降,WISP-3对高氧诱导的肺上皮细胞凋亡具有保护作用。

Objective To explore how Wnt-1 inducible signaling pathway protein-3 （WISP-3） participate in and play a regulatory role in the process of hyperoxia induced apoptosis in lung epithelial cells. Methods The expression of WISP-3 was detected via Western blot and immunohistochemistry. High expression and low expression of WISP-3 were performed by plasmid transfection and siRNA. Cell viability and flow cytometry were executed to detect the hyperoxia-induced apoptosis in Beas-2B. Results Compared to the group of air control,the expression of WISP-3 protein in lung epithelial cells decreased obviously after hyperoxia. Cell survival decrease and apoptosis increased after hyperoxia in Beas-2B cells with low expression of WISP-3. Vice versa. Conclusion The expression of WISP-3 decreased after hyperoxia in lung epithelial cells. The role of WISP-3 in this process may be protective.
