Objective To evaluate the clinical outcomes of double-port video-assisted thoracoscopic lobectomy. Methods We retrospectively analyzed the clinical data of 72 patients who underwent double-port video-assisted thoracoscopic lobectomy(DP group)from October 2014 to December 2015 in our hospital.A paired comparison was made with 72 patients who had the same lesion location and the nature(benign or malignant)and underwent three-port video-assisted thoracoscopic lobectomy(TP group)in the same period.The clinical outcomes included operation time, intraoperative blood loss,the number of lymph node, the chest tube time,postoperative hospital stay, incision pain VAS scores within three days and complications.Postoperative follow-ups were taken with telephone calls or out-patient reviews. Results No operative morality occurred in both groups.There were no statistical significances between the DP Group and the TP Group in intraoperative blood loss[(107.9 ±56.6)ml vs.(95.0 ± 46.8)ml,t=1.490,P=0.138],the number of lymph node(13.9 ±2.7 vs.14.5 ±2.6,t=1.358,P=0.177)and complication rate[11.1%(8/72)vs.9.7%(7/72),χ2=0.074,P=0.785].The DP group had significant longer operation time[(153.6 ± 22.6)min vs.(143.6 ±25.8)min, t=2.474, P=0.015], shorter chest tube time[(5.2 ±1.7)d vs.(6.4 ±1.1)d, t=5.029,P=0.000],shorter postoperative hospital stay[(6.1 ±1.6)d vs.7.6 ±1.2, t=6.364, P=0.000], and lower incision pain VAS scores within three days[(12.3 ±1.9)points vs.(14.4 ±1.8)points, t=6.808, P=0.000]as compared to the TP group.No short-term complication was noticed in both groups during a follow-up time ranged from 6 to 20 months. Conclusions Double-port video-assisted thoracoscopic lobectomy is safe and feasible.It is a preferred surgical mode for selected cases.

Objective To optimize the cerebral ischemia-reperfusion process for acute ischemic stroke patients,so as to reduce the time of in-hospital delays.Methods A multi-disciplinary management team was established to design the flowchart of the cerebral ischemia-reperfusion process for acute ischemic stroke patients.By applying Healthcare Failure Mode and Effect(HFMEA) management mode,intervention was conducted and its effect was analyzed.Results After implementation of the HFMEA intervention,the door to needle time(DNT)was reduced from 88 (42,140) minutes to 45 (37,59) minutes(P＜0.001);the ratio of patients with the DNT＜60 minutes increased from 20％ to 87.7％(P＜0.001);the door to cerebral ischemia-reperfusion time was shortened from 207(169,227) minutes to 165(155,185) minutes (P＜O.05).There was no significant difference in the incidence and mortality of symptomatic cerebral hemorrhage between before and after intervention (P＞0.05).Conclusion Utilization of HFMEA to optimize the emergency cerebral ischemia-reperfusion process can effectively reduce the in-hospital delays of acute ischemic stroke patients.

OBJECTIVE: To explore the possible mechanism of brain damage and memory impairment in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) by detecting the memory, serum S100beta protein, neuron specific enolase( NSE) and analyzing the relationship among them. METHOD: Thirty patients with moderate or severe OSAHS (AHI > 20/h) and twenty normal controls were included in this study. All subjects were detected by polysomnography in the sleep laboratory and the memory of them were evaluated before PSG examination. Memory tests including point memory, association learning, picture free recall, meaningless picture recognition, face characters associated memory have been conducted. The serum S100beta protein was detected by ELISA and the serum NSE was detected by immunoradiometric assay. The relationship between memory and serum S100beta as well as NSE were analyzed in both experiment group and control group. RESULT: The score of point memory, association learning, meaningless picture recognition, face characters associated memory and memory quotient in patients with OSAHS was significantly lower than control group (P < 0.05). The serum S100beta and NSE level was significantly higher than control group (P < 0.05); and correlated positively with AHI as well as ODI; and correlated negatively with MSaO2. Memory quotient correlated negatively with AHI, ODI, serum S100beta and NSE level; and correlated positively with LSaO2, MSaO2. CONCLUSION Memory impairment were present in patients with OSAHS. The increased level of serum S100Beta and NSE may be one of the mechanisms of brain damage and memory impairment in with, OSAHS. And nocturnal hypoxia may contribute to the increased level of serum S100beta and NSE.

Objective: To explore the clinical features and prognosis in patients with Takayasu arteritis (TA) combining neurological symptoms. Methods: We retrospectively studied 274 TA patients combining neurological symptoms who admitted to our hospital from 2002-01 to 2013-10 for their clinical and imaging features with prognosis. Results: The ratio of male to female was 1:4.3 and the mean age of disease onset was at (28.2±11.2) years. The most common neurological symptom was dizziness (214/274 cases, 78.1%), most frequent type was type III TA (112 cases, 40.9%), most common affected artery was left subclavian artery (147 cases, 53.6%), and there were 77 cases (28.1%) with (3-4) branches of the aortic arch involvement. For stroke conditions, ischemic stroke was more frequently observed in patients with steno-occlusive lesions in subclavian artery and common carotid artery, while hemorrhagic stroke was more frequently found in patients with steno-occlusive lesions in descending aorta, abdominal aorta and/or renal artery. Heart failure was the most common cause of death, it was also the most common cardiovascular event in surviving cohorts. Conclusion: TA patients could have many neurological symptoms, which were related to the number and site of artery involvement.

Objective: To explore a single center large cohort of patients with Takayasu’s arteritis for their clinical manifestation and long-term outcome in China. Methods: We retrospectively analyzed 566 patients with Takayasu’s arteritis admitted in our hospital from 2002-01 to 2013-11 for their clinical characteristics, laboratory ifndings, angiographic features, treatment and long-term outcomes. Results: The patient’s ratio for female to male gender was 1 to 3.8 and the average onset age was (28.9 ± 12.0) years. The most common non-speciifc symptom, initial symptom and complication were fever (52/566 patients, 9.2%), dizziness (214 patients, 37.8%) and hypertension (392 patients, 69.3%) respectively. The patients with pulmonary artery and coronary artery involvement were 83 (14.7%) and 66 (11.7%) respectively, and 131 (23.1%) patients had faster erythrocyte sedimentation rate. The major vascular damage was steno-occlusive lesion and the most common involvement was left sub-clavian artery, which was observed in 278 (49.1%) patients. The treatments were mainly included in medication, interventional therapy, autologous blood vessel transplantation, artiifcial blood vessel transplantation and aortic valve replacement. There were 32 patients died during the mean follow-up period of (5.0 ± 0.2) years. Hypertension, complication and the progressive stage of disease were the major factors affecting prognosis in relevant patients (regression coefifcients: 4.664, 1.959 and 1.870 respectively, allP<0.05). Conclusion: Hypertension was the leading reason for patients’ hospital visit. Takayasu’s arteritis was closely related to cardiovascular disease, the early diagnosis and treatment were really important in clinical practice.

Objective To investigate the effects of cholinergic signal on neural stem cell(NSC)differenti-ation in peri-infarction region after ischemic stroke. Methods Mice were randomly assigned into sham + vehicle group,middle cerebral artery occlusion(MCAO)+ vehicle group,MCAO + donepezil group and MCAO + atro-pine group(n = 25). MCAO was induced by thread-occlusion method. Modified neurological severity score (mNSS)was used to evaluate neurological function recovery,and the brain water content was measured by dry-wet weight method. NeuN/5-bromodeoxyuridine(BrdU),CNPase/BrdU,GFAP/BrdU double-labeled cells were tested by immunofluorescence. Results Brain water content of MCAO + vehicle group was significantly higher than that of sham operation group(P < 0.05). Donepezil-treated MCAO mice had lower neurologic deficit scores and brain water content than of MCAO + vehicle group(P < 0.05). On day 14 and day 28 after MCAO,the NeuN/BrdU, CNPase/BrdU and GFAP/BrdU immune-positive cells of MCAO + vehicle group were markedly increased as com-pared with that of sham+vehicle group(P<0.05).Compared with that of MCAO+vehicle group,the number of NeuN/BrdU-positive cells,CNPase/BrdU-positive cells and GFAP/BrdU-positive cells was higher in MCAO+done-pezil group,and the number of NeuN/BrdU-positive cells and CNPase/BrdU-positive cells of MCAO + atropine group was lower(P < 0.05). Conclusions Cholinergic signal could promote NSCs differentiation in peri-infarc-tion region,a lleviate cerebral edema,and improve the brain function restoration after stroke.
