Sleep disorder is a common complication after is chemicstroke.If it is nottimely diagnosed and treated, it may affect the rehabilitation of stroke and recurrence. The manifestations of sleep disorders have various forms according to the different locations of infarction. For the treatment of sleep disorder after stroke, the method of the combination of drugs and physical therapy is used in clinical practice at present. In recent years, w ith the w idely use of the polysomnography, poststroke sleep disorders can be diagnosed clearly and carefuly. The treatment for sleep disorders after stroke may significantly improve the prognosis of patients.

Diabetes mellitus is an independent predictor of high platelet reactivity after antiplatelet therapy in patients with ischemic stroke,and the latter is closely related to the increased risk of recurrence of stroke.The mechanisms of high platelet reactivity in patients with diabetes or insulin resistance are associated with a variety of factors.Some circulating molecules can be used as markers for predicting the reactivity of platelets.Monitoring of platelet reactivity after treatment with new antiplatelet agents may provide basis for individualized antithrombotic therapy in ischemic stroke patients with diabetes or insulin resistance.

Clopidogrel can inhibit platelet aggregation and reduce the risk of recurrent stroke.However,it is a great difference in antiplatelet inhibition in different populations.This article reviews the mechanism of clopidogel resistance and its countermeasures in the prevention of ischemic stroke.

Objective To investigate the clinical value of stereotactic biopsy in the diagnosis of the multiple intracranial lesions, and explore the operation methods, technical points and clinical experiences to reduce surgical complications. Methods Twenty-three patients in the first affiliated hospital of Kunming Medical University underwent stereotactic biopsy from January 2009 to June 2013 were analyzed retrospectively. The patients were aged between 11 and 73 years (the mean age of 34.6 years) . There were 12 males and 11 females. Operations were performed by thin thickness of spiral CT scan, ASA-602S and Leksell-Frame-G stereotactic frame, Sedan side-cutting needle, Backlund side-cutting needle and neuroendoscope of STORZ. Routine histopathological examinations of specimens were conducted. The immunohistochemical staining of the histopathological section of specimens was performed if necessary. Results The diagnostic yield was 91.3% (21 cases) . The result of pathological diagnosis was inflammatory granuloma in 1, inflammatory lesion in 1, calcification in 1, hyperplasia of colloid cells in 6, astrocytoma in 1 (WHOⅠ-Ⅱ), astrocytoma in 2 (WHOⅡ), astrocytoma in 1 (WHOⅡ-Ⅲ), mixed oligoastrocytoma in 1 (WHOⅠ-Ⅱ), glioblastoma multiforme in 3 (WHOⅣ), germinoma in 1, brain metastases in 1, diffuse large B-cell lymphoma in 1, intracranial granulomatousarteritis in 1 and negative in 2. There were no serious complications, such as coma, hemiparalysis, infection and intracranial hematoma. Conclusion Stereotactic biopsy is an important method in the diagnose of multiple intracranial lesions. It has the advantages of precise location, less damage, safe performance, and reducing the complication effectively. It is worth promoting.

Objective To investigate the correlation between serum cystatin C (CysC) levels and cerebral microbleeds (CMBs) in patients with acute ischemic stroke.Methods The patients with acute ischemic stroke were enrolled.Susceptibility weighted imaging was used to identify the presence of CMBs.Particle-enhanced turbidimetric immunoassay was used to detect the levels of serum CysC.Results A total of 485 patients with acute ischemic stroke were enrolled,including 151 (31.1％) with CMBs.The level of serum CysC of the CMB group was significantly higher than that of the non-CMB group (1.24± 0.13 mg/L vs.1.02± 0.11 rmg/L; t=4.261,P＜ 0.001).Multivariate logistic regression analysis showed that the increased serum CysC level was an independent risk factor for the presence of CMBs in patients with acute ischemic stroke (each increase in one standard deviation,odds ratio 4.063,95％ confidence interval 2.142-8.127; P ＜0.001).Multiple linear regression analysis showed that the number of CMBs in patients with acute ischemic stroke increased with the increasing serum CysC level after adjusting for other confounders (r2 =0.361,P =0.017).Conclusions In patients with acute ischemic stroke,the serum CysC levels are independently associated with the CMBs,and the number of CMBs increases with the serum CysC level.

OBJECTIVE:To systematically review the related evidence-based guidelines of purulent meningitis in children,and to provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed,EMBase,CBM,Wanfang Data-base,CJFD and VIP,NGC,GIN,TRIP and websites of domestic and international medical associations and industry bodies,the treatment guidelines about purulent meningitis in children were collected. Evidence-based evaluation was performed after data extrac-tion and quality evaluation. RESULTS:Finally 3 guidelines were enrolled in total,with development time ranging from 2004 to 2012,from USA,Britain and Australia,respectively. All of the recommendations were level B,scope and purpose and clarityshowed the higher scores in AGREEⅡ,more than 70%,and applicability showed generally low scores. Penicillin and cefotaxi-me were recommended in purulent meningitis of neonates,and vancomycin combined with cefotaxime or ceftriaxone were recom-mended for infants and children(it was combined with vancomycin when Streptococcus pneumoniae infection was suspected). The dose and duration of each guideline were certain different,and the period of treatment should be longer in neonates. In addition, the glucocorticoid was recommended in all guidelines. CONCLUSIONS:The recommendations of medicines for the treatment of pu-rulent meningitis are basically unanimous,with no regional difference,but there are some differences about dose and the course of treatment. In addition,the classification criteria of the levels of evidence and recommendation are still suboptimal,which needs fur-ther improvement. And guidelines on purulent meningitis should be improved inrigourandapplicabilityin future.

Objective Toexplore the application value of diffusion tensor imaging (DTI) in evaluating evaluation offunctional changes of the in patients with primary trigeminal neuralgia caused (PTN) by neurovascular compression. Methods 40 unilateral PTN patients and 40 healthy volunteers were enrolled in ourstudy.They allAll patients underwent the general sequences and DTI ,and then to measured the ADC and FA values of the trigeminal nerves. Results (1) Compared with contralateral side (0.408 ± 0.054)and bilateral sides in control group(0.423 ± 0.057), FA value of the ipsilateral side in PTN group(0.330 ± 0.056) was significant lower (P< 0.05)compared with the contralateral side (0.408 ± 0.054) and bilateral sides in control group (0.423 ± 0.057).The ADC value of ipsilateralside (2.052 ± 0.473)× 10-3 mm2/s was significantly higher (P < 0.05) thancompared withthe contralateral side (1.541 ± 0.266) ×10-3 mm2/s and bilateral sides in control group(1.431 ± 0.308) ×10-3 mm2/s. (2) An There's a nnegative correlation was found (r = -0.613,P < 0.001) between the loss of FA and the increase of ADC (r = -0.613,P < 0.001). Conclusion DTI could be used to evaluate the changes of neuratrophy and demyelination ,so it canmight be used of in diagnosis and treatment of PTNin further way.
