目的 评估光动力疗法联合曲安奈德治疗渗出型老年性黄斑变性（AMD）的临床疗效及对患者生活质量的影响。 方法 将2007年12月－2010年12月就诊的35例（38只眼）渗出型AMD患者采用随机数字表法随机分为两组，治疗组18例（20只眼）采用光动力疗法联合玻璃体腔内注射曲安奈德治疗，对照组17例（18只眼）单用光动力疗法。评估患者视力和眼底影像学改变，同时也评估对患者生活质量的影响。两组均随访12个月。 结果 随访12个月后，光动力疗法联合曲安奈德治疗组视力不变者8例9只眼，占45.0%；视力提高者9例10只眼，占50.0%；视力下降者1例1只眼，占5.0%。吲哚青绿血管造影结果显示，脉络膜新生血管（CNV）渗漏停止7例7只眼，占35.0%；持续渗漏或渗漏增加者1例1只眼，占5.0%；渗漏减少者11例12只眼，占60.0%。光动力疗法治疗组视力不变者6例6只眼，占33.3%；视力提高者4例5只眼，占27.8%；视力下降者7例7只眼，占38.9%。吲哚青绿血管造影结果显示，CNV渗漏停止3例3只眼，占16.7%；持续渗漏或渗漏增加者5例6只眼，占33.3%；渗漏减少者9例9只眼，占50.0%。联合治疗组与单用光动力疗法组在视力改变方面差异有统计学意义（χ2=4.67，P=0.03），在吲哚青绿血管造影结果方面差异有统计学意义（χ2=3.35，P=0.01）。中文译本低视力者生存质量量表评估生活质量治疗组平均得分（102.02 ± 16.20）分，对照组平均得分为（91.27 ± 11.81）分，两组比较差异有统计学意义（P＜0.05）。 结论 光动力疗法联合曲安奈德治疗渗出型AMD疗效优于单用光动力疗法。
Objective To explore the predictive value of superoxide dismutase (SOD) and serum amyloid A (SAA) in short-term poor prognosis in patients with lacunar infarction. Methods The clinical data of 185 patients who were diagnosed with lacunar infarction in the Second Affiliated Hospital of Wannan Medical College between January 1st and December 31st, 2021 were analyzed retrospectively. According to the modified Rankin Scale (mRS) score 3 months after discharge, the patients were divided into the good prognostic group (mRS≤2) and the poor prognostic group (mRS>2). Multiple logistic regression was used to analyze the independent risk factors of the short-term adverse prognosis of patients with lacunar infarction, and a risk prediction model (nomograph) was constructed. The predictive efficacy of SOD, SAA and nomograph for poor prognosis was analyzed by using the receiver operating characteristic curve. Calibration curve and decision curve analysis were used to evaluate the differentiation and clinical application value of the model. Results A total of 185 lacunar cerebral infarction patients with a mean age of (68.26±10.77) years were enrolled in this study, among whom 80 (43.2%) were males and 39 (21.1%) had adverse prognosis. Multiple logistic regression analysis showed that systolic blood pressure [odds ratio (OR)=1.028, 95% confidence interval (CI) (1.004, 1.052), P=0.021], diabetes [OR=4.939, 95%CI (1.703, 14.320), P=0.003], SAA [OR=1.089, 95%CI (1.052, 1.128), P<0.001], apolipoprotein B [OR=7.647, 95%CI (2.186, 26.753), P=0.001] were independent risk factors for poor prognosis in lacunar infarction patients, while the level of SOD [OR=0.979, 95%CI (0.965, 0.994), P=0.006] was a protective factor. The area under the curve of the nomograph for predicting the short term poor prognosis was 0.874 [95%CI (0.812, 0.936), P<0.001]. The goodness-of-fit test with the calibration curve indicated that the prediction probability was consistent with the actual occurrence probability (Hosmer-Lemeshow test P=0.295), and the decision curve indicated that the nomograph had good clinical application value. Conclusion SAA and SOD have good predictive value for short-term adverse prognosis of lacunar cerebral infarction patients, and the nomograph constructed based on them has a good differentiation and consistency, which can provide a basis for clinicians to evaluate the prognosis of lacunar cerebral infarction patients.
Objective To explore the risk factors of nosocomial pulmonary infection in acute pesticide poisoning. Methods The clinical data of patients with acute pesticide poisoning hospitalized in the Emergency Department of the First Affiliated Hospital of Wannan Medical College and the Second Affiliated Hospital of Wannan Medical College between January 1, 2021 and September 30, 2023 were retrospectively analyzed. Patients were divided into pulmonary infection group and non-pulmonary infection group according to whether they had pulmonary infection during hospital. Multiple logistic regression was used to analyze the independent risk factors of nosocomial pulmonary infection in patients with acute pesticide poisoning, and a risk prediction model (nomogram) was constructed. The predictive efficacy of nomogram and independent predictors in nosocomial pulmonary infection were analyzed by using the receiver operating characteristic curve. Calibration curve and decision curve were used to evaluate the differentiation and clinical application value of the model. Results A total of 189 patients with acute pesticide poisoning were included in the study, with an average age of (58.12±18.45) years old, 98 males (51.85%) and 91 females (48.15%). There were 36 cases (19.05%) of pulmonary infection. Multiple logistic regression analysis showed that age [odds ratio (OR)=1.030, 95% confidence interval (CI) (1.001, 1.060), P=0.040], type 2 diabetes mellitus [OR=2.770, 95%CI (1.038, 7.393), P=0.042], ischemic cerebrovascular disease [OR=3.213, 95%CI (1.101, 9.376), P=0.033], white blood cell count [OR=1.080, 95%CI (1.013, 1.152), P=0.019], activities of daily living score [OR=0.981, 95%CI (0.965, 0.998), P=0.024] were independent predicting factors for nosocomial pulmonary infection in acute pesticide poisoning. The area under the curve of nosocomial pulmonary infection in patients with acute pesticide poisoning predicted by nomogram based on the above factors was 0.813 (P<0.001). The calibration curve showed that the prediction probability was consistent with the actual occurrence probability (P=0.912), and the decision curve showed that the nomogram had good clinical application value. Conclusions Age, activities of daily living score, type 2 diabetes mellitus, ischemic cerebrovascular disease, and white blood cell count are independent predictors of nosocomial pulmonary infection in acute pesticide poisoning. The nomogram constructed based on them has good differentiation and consistency, which can provide basis for early identification and intervention of clinical staff.
