目的 探讨老年急性缺血性脑卒中并发肺部感染患者的临床特征和相关危险因素。方法 采用回顾性研究方法,选择2017年7月— 2019年10月深圳市第二人民医院神经内科收治的1 113例老年急性缺血性脑卒中患者,其中卒中并发肺部感染患者(108 例)纳入感染组,未并发肺部感染患者(1 005例)纳入对照组。以单因素对比分析两组患者的临床资料,采用 Logistic多因素回归分析方法分析合并肺部感染的高危因素。结果 单因素分析提示两组年龄(尤其是高龄患者)、住院天数、房颤、脑梗死史、慢性肺疾病、吞咽困难、言语不清、意识障碍差异有统计学意义(P <0.05)。多因素 Logistics 回归分析显示,高龄(≥80岁)、住院天数、脑梗死史、吞咽困难、言语不清、意识障碍与老年急性缺血性脑卒中并发肺部感染密切相关。结论 老年急性缺血性脑卒中并发肺部感染的独立危险因素主要是高龄(≥80 岁)、住院天数、脑梗死史、吞咽困难、言语不清、意识障碍,临床应高度重视。

Objective Objective To investigate the clinical characteristics and risk factors of elderly patients with acute ischemic stroke complicated with pulmonary infection. Methods A retrospective study was conducted on 1 113 elderly patients with acute ischemic stroke admitted to the department of neurology, Shenzhen Second People's Hospital from July 2017 to October 2019. Among them, 108 patients with stroke complicated with pulmonary infection were included in the infection group and 1 005 patients without concurrent pulmonary infection were included in the control group. The clinical data of the two groups were analyzed by single factor comparison, and the risk factors for pulmonary infection were analyzed by logistic multiple factor regression analysis. Results Single factor analysis showed there were statistically significant differences between the two groups in age (especially elderly patients), length of stay in hospital, atrial fibrillation, history of cerebral infarction, chronic pulmonary disease, dysphagia, slurred speech, and disturbance of consciousness (P <0.05). Multi-factor logistic regression analysis showed that old age (≥80 years old), length of stay in hospital, history of cerebral infarction, dysphagia, slurred speech, and disturbance of consciousness were closely related to pulmonary infection in elderly patients with acute ischemic stroke. Conclusion The independent risk factors of acute ischemic stroke complicated with pulmonary infection in the elderly mainly include old age (≥80 years old), length of stay in hospital, history of cerebral infarction, dysphagia, slurred speech and disturbance of consciousness, which should be paid more attention to clinically.

目的 探讨磁共振磁敏感加权成像(SWI)对脑膜、脑转移瘤的诊断价值。方法 随机选取2016年3月—2018年3月我院收治的经临床、病理确诊的50例脑膜、脑转移瘤患者为研究对象,所有患者除常规行T1WI、T2WI扫描及T1WI增强扫描检查外,额外进行SWI检查。观察不同来源脑转移瘤转移部位、肿瘤实质信号在不同成像序列上的特征及对瘤内血管情况和出血状况的判断。结果 脑转移瘤的发生部位多为顶叶(29.75%)和枕叶(20.66%),就血供区域而言,多发生于中动脉(45.45%)和颈内动脉供血区域(38.02%)。不同MRI成像序列中肿瘤信号特征比较,显示均有差异(P<0.001)。其中,肺癌脑转移瘤T1WI呈低信号(62.96%),胃癌T2WI呈现高信号(68.75%),SWI成像序列上多显示为混杂信号。SWI序列成像显示瘤内出血55例(45.45%),显示引流血管16条,瘤内出血及肿瘤血管检出率均明显高于T1WI平扫检查,差异有统计学意义(P<0.05)。结论 不同来源的脑转移瘤MR的表现不同,为逆向推测脑转移瘤来源提供依据,同时SWI是对常规序列的重要补充,尤其是在脑瘤出血和血管检出上有重要作用,值得临床推广使用。

Objective To investigate the diagnostic value of susceptibility-weighted imaging(SWI) in meningiomas and brain metastases. Methods 50 cases of clinically and pathologically confirmed patients with meningioma and brain metastasis admitted to our hospital from March 2016 to March 2018 were randomly selected as the study subjects. All patients received routine T1WI, T2WI scan and T1WI enhanced scan, and additional SWI examination was performed. We observed the characteristics of metastatic sites and tumor parenchymal signals in different imaging sequences of brain metastatic tumors from different sources and to judge the status of intramedullary blood vessels and bleeding. Results The majority of brain metastatic tumors occurred in the parietal lobe (29.75%) and occipital lobe (20.66%). In terms of the blood supply region, the majority occurred in the middle artery (45.45%) and the blood supply region of the lower artery (38.02%). Comparison of tumor signal characteristics in different MRI imaging sequences showed differences, P<0.001. Among them, T1WI of brain metastatic tumor of lung cancer presented significantly low signal (62.96%), T2WI of gastric cancer presented high signal (68.75%), and SWI imaging sequence mostly showed mixed signal.SWI sequence imaging were showed in 55 cases (45.45%) of intracranial hemorrhage and 16 drainage vessels. The detection rate of intracranial hemorrhage and tumor blood vessels was higher than that of T1WI plain scan, with statistically difference (P<0.05). Conclusion MR manifestations of brain metastatic tumors from different sources are different, providing a basis for reverse speculation of the source of brain metastatic tumors. At the same time, SWI is an important supplement to routine sequences, especially in the hemorrhage of brain tumors and the detection of blood vessels, which is worthy of clinical promotion and use.

Objective To evaluate a 3-year mid-term clinical results of FAST-FIX suture system in arthroscopic meniscal posterior horn repair. Methods Clinical results of 46 patients with meniscal tear who underwent posterior horn of the meniscus repair using the FAST-FIX suture system from January 2011 to April 2013 were retrospectively analyzed. There were 27 males and 19 females,age 17~42 years old,average 23.5±8.22 years old. There were 25 left knee and 21 right knee and 33 red zone injury and 13 red-white zone injury, 8 of which were accompanied by anterior cruciate ligament injury. Clinical healing of the meniscus was assessed by Lysholm scores(35.73±11.28)points,IKDC scores(37.26±13.17)points and Tegner scores(3.3±1.7)points before operation. Results The average follow-up period was 46.3 months (range: 36-59 months). The clinical healing rate was 91.3%. Healing failure occurred to 4 patients and 2 of which had a meniscus noose after operation and were confirmed surgical failure in reoperation. Mean Lysholm scores were (86.31±11.89),IKDC scores(82.9±13.44)and Tegner scores(5.9±1.9)in 3 years after operation for all 46 cases. The differences between the preoperative and postoperative scores in three type scores were statistically significant (P<0.05). Conclusion Arthroscopic posterior horn of the meniscus repair with the FAST-FIX suture system may provide good 3-year mid-term clinical results after operation.

Objective To study the clinical application value of the fiberoptic ductoscopy(FDS) on the diagnosis of nipple discharge. Methods A retrospective analysis of 123 patients with nipple discharge undergoing FDS from February 2010 to March 2014. Results After fiberoptic ductoscopy examination,it was found there were 8 cases of breast cancer,33 cases of intra-duct papilloma,35 cases of papillomatosis,35 cases of dilatation and inflammation. However there were 5 cases of breast cancer,35 cases of intra-duct papilloma,30 cases of papillomatosis, and 33 cases of dilatation and inflammation were comfirmed through postoperative pathological examination. Conclusion Fiberoptic ductoscopy is more effective than B-ultrasonography and Mo-traget mammography, so it can be the preferred method of diagnosis and treatment for nipple discharge.
