Objective To study the effect of inducible nitric oxide synthase(iNOS)on the occurrence of ischemic cerebral stroke in passive smoking female.Methods 100 passive smoking female patients with ischemic cerebral stroke(passive smoking group) according to the passive smoking index were divided into sub-groups index 900;25 cases in each group.The level of serum iNOS and the situation of carotid atherosclerosis were detected.The resules were compared with healthy female who without smoking and passive smoking(normal control group).Results Compared with the normal control group,the levels of serum iNOS,the intimal media thickness(IMT)s of carotid artery and the positive rates of carotid atherosclerosis plaque in each passive smoking index sub-group were significantly increased(all P

Objective To investigate the effect of the 5-hydroxytryptamine (5-HT) on the occurrence,development of post-stroke depression (PSD).Methods The literatures on the relationship between 5-HT and PSD were selected from databases such as Wanfang Data,CNKI and PubMed before in 2010-2014.According to absorption and exclusion criteria of the literature,collect literatures,and summary,induce and analyze on them.Results Search 258 literatures and accept 44 literatures accorded with the criteria,including the relationship between 5-HT and PSD,the relationship between 5-hydroxytryptamine receptor (5-HTR) gene polymorphism and PSD,the relationship between 5-hydroxytryptamine transporter linked promoter region (5-HTTLPR) and PSD,and the treatment of selective serotonin reuptake inhibitors (SSRIs) in PSD.Conclusion Reduced levels of 5-HT lead to the occurrence of PSD,and they had a negative correlation;5-HTR 1 A,5-HTR2A are related genes of PSD;S allele and S/S genotype is susceptible factors of PSD,while the L allele is the protective factors of PSD;SSRIs can increase the level of 5-HT in the synaptic gap so as to improve the depressive symptoms of PSD.In the future,it is necessary to increase the sample size to confirm the relationship between 5-HT and PSD,and combine with other factors to explore the relationship between them.

Objective To evaluate the safety and efficacy of early carotid artery stenting in treating cerebral watershed infarction patients with carotid artery stenosis. Methods A total of 33 patients with acute cerebral watershed infarction complicated by carotid artery stenosis received carotid artery stenting within one week after the onset of the disease. The clinical safety and efficacy were evaluated. Results The carotid artery stenting was successfully accomplished in all 33 patients with a success rate of 100%. After the procedure, different degree of bradycardia and hypotension was seen in 23 patients, which restored to normal after prompt medication with atropine, dopamine, etc. During the procedure, one patients developed cerebral embolism due to dislodgment of emboli, resulting in contralateral hemiparalysis, and the contralateral limb muscle strength returned to preoperative status after proper treatment. After the treatment, no ipsilateral hemisphere excessive perfusion or cerebral hemorrhage occurred. Thirty days after the treatment, NHISS scores of the patients were obviously improved, which were significantly different from those determined before the treatment (P<0.05). Conclusion For the treatment of acute cerebral watershed infarction, early carotid artery stenting to relieve carotid artery stenosis is quite safe and it may improve the prognosis as well.

Post-stroke aphasia is an acquired language disorder caused by stroke.It impaired the quality of life of patients and brought a heavy burden to family and the society.Unfortunately,the highly variable predictive factors make the prognosis of aphasia recovery difficult.Much of the researches indicated that the post-stroke aphasia recovery is associated with the patient-related and stroke-related factors.We searched the recent advances on the influence of patient-related factors and stroke-related factors on aphasia recovery.It showed that patient-related factors have no obvious effect on predicting aphasia recovery while the lesion (stroke)-related factors appeared close correlation with post-stroke aphasia recovery.The clinicians should pay more attention on lesion (stroke)-related factors when evaluate the outcome and give the intervention measures.

To investigate the effect of C/EBP βon the neuroinflammation.Recently,neuroinflamma-tion research mainly focused on C/EBP β,more and more researches indicated that C/EBP βmay play an important role in neurodegenerative diseases.We searched the published papers in PubMed,CNKI,and Wan Fang date bases in June 2015.The key words were used asCCAAT enhancer binding protein beta,Neu-ron,Neuroinflammationand so on.According to the inclusion and exclusion criteria, we summaried and analyzed the literatures.Eventually,42 articles were adapted,most of which were foused on the functions and mechanisms of C/EBP βin neuroinflammation.C/EBP βparticipate in multiple signaling pathways of neu-roinflammation,and the regulation mechanism is complicated.Abrogation of C/EBPβexpression or its down-regulation by gene regulation may may serve as a therapeutic target to attenuate deleterious effects in neural tissue and ultimately prevent the development of neurodegenerative disorders.

Objective To investigate the effectiveness and safety of carotid stenting for progressive cerebral watershed infarction (PCWI) patients with ipsilateral internal carotid stenosis or occlusion during the progressive stage. Methods The clinical data of 23 PCWI patients with ipsilateral internal carotid stenosis or occlusion treated with carotid stenting during the progressive stage were analyzed retrospectively. Among them, 18 were severe internal carotid artery stenosis, and 5 were carotid artery occlusion. Carotid artery stenting were performed in patients with severe internal carotid artery stenosis. The first-stage angioplasty and second-stage stenting were performed in patients with internal carotid artery occlusion. The National Institutes of Health Stroke Scale (NIHSS) score and the modified Rankin scale (mRS) were used to evaluate preoperative and postoperative neurologic deficits. Results Twenty-two of 23 patients were stented successfuly, the Thrombolysis In Myocardial Infarction (TIMI) flow grade was 3, and the technical success rate was 95. 7% . None of the patients demonstrated hyperperfusion in the ipsilateral hemisphere. At day 30 postprocedure, the NHISS scores were significantly improved compared with before procedure (4. 41 ± 1. 88 vs. 10. 00 ± 1. 47; t = 11. 234, P < 0. 001). The preprocedural TIMI flow grade was 3 in 12 patients (52. 2% ). Proportion of patients with TIMI flow grade 3 after procedure was significantly increased compared with before procedure (95. 7% vs. 52. 2% ; χ2 = 11. 274, P = 0. 002). The proportion of patients with mRS scores 0-2 at day 90 after procedure was significantly increased compared with before procedure (69. 6% vs. 0% ; χ2 = 24. 533, P < 0. 001). Conclusions Carotid stenting during the progressive stage is safe and it may improve the prognosis in PCWI patients with ipsilateral internal carotid stenosis or occlusion.

OBJECTlVE To study the reIationship between microRNA(miRNA)-122 and Iiver injury in-duced by anti-tubercuIosis drugs,and to discover the new biomarkers for earIy diagnosis of this type of Iiver injury. METHODS mice were given 2 mL isoniazid oraIIy at 90 mg·kg-1 . BIood and Iiver tissue sampIes were coIIected at 1,3,5,7,14,21 and 28 d after administration of isoniazid. Serum gIutamic-pyruvic transaminase( GPT)and gIutamic-oxaIoacetic transaminase( GOT)IeveIs were determined using an automatic biochemicaI anaIyzer. Cu/ Zn-superoxide dismutase( Cu/ Zn-SOD ) activity and maIondiaIdehyde( mDA)content were detected by biochemicaI method. ReaI-time qPCR was used to measure the expression of miRNA-122. RESULTS GPT and GOT IeveIs were significantIy higher at 14 and 21 d(P﹤0.05)than in the controI. Cu/ Zn-SOD began to decIine whiIe mDA began to increase after 5 d(P﹤0.05). miRNA-122,which progressiveIy decreased after administration,was reduced to the mini-mum 0.58 ±0.02 at 14 d. There were good correIations between miRNA-122 and GPT,Cu/ Zn-SOD, mDA(the correIation coefficients were -0.370,0.268,and -0.298,respectiveIy),but no correIation with GOT was observed. CONCLUSlON The tissue miRNA-122 profiIe can be used as a sensitive marker for anti-tubercuIosis drug-induced Iiver injury,which couId contribute to the earIy diagnosis of Iiver injury.

ObjectiveTo discuss the relationships among spastic paralysis and motor function, balance function and other clinical variables after stroke.MethodsAssessed the clinical spastic index of hemiplegic lower limbs with CSI scale, motor function with Fugl-Meyer Assessment, and balance function with Berg Equilibrium Scale, respectively. And then analyzed the relationship between clinical spasm index with motor function, balance function of the hemiplegic lower limbs with Pearson correlation analysis. Finally, ascertained which was the most important factor affecting the clinical spasm index of spastic lower limbs with stepwise regression analysis.ResultsThere is negative correlation between clinical spasm index with motor function and balance function, respectively. Tendon reflex, muscular tension and clonus are the deciding factors to motor function(P<0.05) and balance function(P<0.05) of the hemiplegic lower limbs.ConclusionThe clinical spasm index of hemiplegic limbs can affect the recovery of motor function and balance function significantly. So, assessing and improving the clinical spasm index of paralytic lower limbs can optimize the rehabilitation program to stroke patients.
