Methods A total of 13 899 blood donors who successfully donated apheresis platelets for the first time in Guangzhou Blood Center from January 1, 2016 to December 31, 2016 were selected as subjects. The correlation among gender, age, education level, adverse reactions of blood donation and whether platelet collection was re-donated in the next year was analyzed. Results Re-donation rate of male blood donors (10.68%) was higher than that of female blood donors (8.94%). The difference was statistically significant (P<0.01). Re-donation rate of blood donors aged 18～25 was the highest 12.86%, and that of 46～60 was the lowest 6.46%. The difference was significant (P<0.001). Re-donation rate of high school or vocational college blood donors was the highest 11.23%. The lowest re-donation rate was 8.94% in the undergraduate group or above, and the difference was statistically significant (P< 0.001). The re-donation rate of donors without adverse reactions (10.37%) was higher than that of donors with adverse reactions (5.56%). The difference was statistically significant (P<0.01). Conclusion Male, younger, less educated and no adverse reactions to blood donation are more willing to return to donate platelet again. Targeting these donors for reserve measure will conducive to the establishment of a fixed platelet donor team.

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.

目的 探讨鼻咽癌(NPC)放疗致鼻窦炎发生的临床特征、影响因素。方法 回顾性分析2014年1月—2017年6月期间,我院收治的228例NPC患者临床资料,根据患者是否进行放疗,将患者分为非放疗组(106例)和放疗组(122例)。对比分析两组鼻咽癌致鼻窦炎的临床特点,以单因素和多因素Logistic分析鼻咽癌患者放疗后发生鼻窦炎的影响因素。结果 放疗组患者鼻窦炎发生率为81.97%,高于非放疗组患者鼻窦炎发生率54.72%,差异有统计学意义(P＜0.05)。放疗组鼻窦炎累及部位发生率从高到低,依次为后组筛窦、蝶窦、前组筛窦、窦口鼻道复合体、额窦以及上颌窦。放疗组患者鼻窦炎后组筛窦、蝶窦累及率高于非放疗组患者,差异具有统计学意义(P＜0.05)。单因素分析结果显示,放疗后鼻窦炎的发生,与患者年龄是否＞50岁,病程是否＞2年,是否存在鼻腔侵犯,肿瘤分期,是否使用滴鼻剂及是否进行鼻咽冲洗有关,差异有统计学意义(P＜0.05)。多因素Logistic回归分析结果显示,患者病程＞2年,存在鼻腔侵犯以及T3+T4期肿瘤是NPC放疗后鼻窦炎发生的独立危险因素;使用滴鼻剂和鼻咽冲洗是NPC放疗后鼻窦炎发生的保护因素。结论 NPC放疗后具有较高的鼻窦炎发生率,并且主要累及后组筛窦和蝶窦,对于病程＞2年、存在鼻腔侵犯以及T3+T4期肿瘤的患者,应积极采取措施预防鼻窦炎的发生,使用滴鼻剂和鼻咽冲洗是预防NPC放疗后鼻窦炎发生的有效措施。

Objective To investigate the clinical features and influencing factors of nasosinusitis caused by nasopharyngeal carcinoma (NPC) radiotherapy. Methods The clinical data of 228 NPC patients admitted to our hospital from January 2014 to June 2017 were retrospectively analyzed. According to whether the patients were treated with radiotherapy, the patients were divided into non-radiotherapy group (106 cases) and radiotherapy group (122 cases). The clinical characteristics of nasosinusitis were analyzed and compared. Univariate and multivariate logistic analysis was used to analyze the influencing factors of nasosinusitis after radiotherapy in patients with nasopharyngeal carcinoma. Results The incidence of sinusitis was 81.97% in the radiotherapy group, which was higher than that in the non-radiotherapy group (54.72%). The difference was statistical significance (P<0.05). The incidence of sinusitis involvement in the radiotherapy group was in the order of ethmoid sinus, sphenoid sinus, anterior ethmoid sinus, sinus ostium and nasal tract sinus complex, frontal sinus, and maxillary sinus. The incidences of ethmoid sinus and sphenoid sinus in the post-nasal sinusitis group were higher than that in the non-radiotherapy group (P<0.05). Univariate analysis showed that the occurrence of sinusitis after radiotherapy was related to whether the patient's age was > 50 years, whether the disease duration was >2 years, whether there was nasal invasion, tumor staging, whether nasal drops were used, and whether nasopharyngeal irrigation was performed. Multivariate logistic regression analysis showed that patients with a disease course of >2 years had nasal invasion and T3+T4 tumors were independent risk factors for sinusitis after NPC radiotherapy; use of nasal drops and nasopharyngeal washing were protective factors. Conclusion There is a higher incidence of sinusitis after radiotherapy of NPC, and mainly affects the ethmoid sinus and sphenoid sinus in the posterior group. Patients with a disease course of >2 years, with nasal invasion, and T3+T4 tumors should actively take measures to prevent the occurrence of sinusitis. The use of nose drops and nasopharyngeal washing is an effective measure to prevent the occurrence of sinusitis after NPC radiotherapy.
