Intracranial arterial stenosis is the most common vascular lesions in patients with acute stroke in Chinese population,and most of them are middle cerebral artery (MCA) stenosis.The treatment of asymptomatic MCA stenosis is mainly to control the risk factors and treat with drugs,and the prognosis is better.Statins can reduce new stroke events.The treatment programs of symptomatic MCA stenosis are mainly to control the risk factors,treat with drugs and stenting.Now it is considered that anticoagulants are not superior to antiplatelet drugs in the treatment of MCA stenosis,but whether dual antiplatelet drugs are superior to monotherapy and stenting remains to be determined.The prognosis of symptomatic MCA stenosis is poor.The prognosis of acute phase mainly depends upon imaging features,and the risk of recurrent stroke is primarily associated with the MCA stenosis.Future research should focus on whether dual antiplatelet therapy is superior to monotherapy,and whether stenting is superior to drug treatment,as well as the relationship between the degree of MCA stenosis and prognosis of acute phase or the risk of recurrent stroke.

Objective To assess the courses of evidence-based medicine among graduate students. Methods A sample of 118 graduate students who took the course were surveyed twice by using the same self-designed questionnaire at the beginning and the end of the course.Pre-post comparison was conducted to measure the impact. Results The students were able to grasp the most of the contents of the course,and reshaped their opinions on evidence-based medicine,with which,a positive impact on their medical practice was expected. Conclusion The course of evidence-based medicine for graduate students has resulted in a positive consequence.

Objective To use peer education to guide community diabetic patients to adopt diet therapy using food exchange method in order to explore effective method for diet therapy of diabetes mellitus. Meth-ods 91 diabetic patients were selected using simple sampling method and randomly divided into the peer ed-ucation(45 cases) and the common education group(46 cases), the two groups adopted food exchange method for diet therapy for 1 year. The blood glucose, blood lipid, glycosylated hemoglobin and body weight index were compared between the two groups using t test. Results The blood glucose, blood lipid, glycosylated hemoglobin and body weight index all decreased in the two groups after intervention, but the the decreased de-gree in the peer education group was more obvious. The fasting blood glucose, 2 hour postprandial blood glu-cose, glycosylated hemoglobin, triglyceride, low-donordensity lipid protein and body weight index in the peer education were lower thanthose of the common education group, but HDL-C was higher. Conclusions Peer education is more effective in health education of food exchange method.

s:Objective To investigate the critical value of neonatal coagulation and the normal reference range in clinical prac-tice,and make Value of the formulation of clinical treatment programs and prevention of neonatal blood coagulation disor-ders.Methods Collected neonatal specimens of 350 cases from January to June 2016 in the General Hospital Ningxia Medi-cal University,after birth with in 6h,the parameters of plasma coagulation:activated partial thromboplastin time (APTT), prothrombin time (PT)clotting time (TT)and fibrinogen (FIB).Made statistics and analysis of all critical information to improve the value of the cases after contact with the telephone registration of neonatology,and critical investigation occurred gestational age children value,birth weight,and critical analysis of the proportion of the value of the proj ect,the distribution of the disease,clinical response and so on.Results Compared with adults and children,four indexes of coagulation levels of newborn were significantly different (t=1.66~2.66,P<0.01),as well as preterm group and term group;additional chil-dren with severe and premature birth or low weight occurs critical the possibility of greater value,and the distribution of high APTT and low FIB profile occured in the most critical values,neonatal jaundice and severe pneumonia was a risk factor critical values outbreak.Overall clinical response rate was 33%,the“answer”and“non response group”in children with in-tracranial hemorrhage of digestive and tract,and the diagnosis rate of statistical results was no significance (χ2=36.68/39, P>0.05).The range of personal critical value of the newborn infant was intended to develop:PT(≤8 s and≥30 s),APTT (≤20 s and ≥90 s)and FIB(≤0.6 g/L and ≥10 g/L).Revised “response rate”,clinicians have increased attention com-pared with the previous increase,reducing the false critical value report incidence.Conclusion The indicators of neonatal co-agulation were different from the adults and children.For the establishment of neonatal blood coagulation parameters refer-ence range,on a regular basis to summary on the clinical data of blood coagulation critical value,and contribute to the devel-opment of suitable critical value standard,and improve the clinical comprehensive diagnosis and treatment level.

Abstract Objective:To investigate whether mRNA of prolactin(PRL) ,an important immunomodulatory hormone,is expressed in thyroidglands of patients with Graves'disease(GD) .Methods:The expression of PRL mRNA was examined by nonisotopic in situ hybridization in GDthyroid glands and the control ones( including multinodular goiters and samples of normal thyroid tissue adjacent to adenomas) as well as intra-thyroidal mononuclear cells isolated from GD thyroid glands and primary thyroid follicular cell(TFC) cultures derived from them.Results:PRL mRNA was expressed in GD thyroid glands, but not in the control ones. It was localized in infiltrating mononuclear cells and vascular endothelial cells adjacent to mononuclear cell infiltrates, but not in TFC .(9.8?.3)% (x ?s) of intrathyroidal mononuclear cells isolated from GD thy-roid were found containing PRL mRNA.It was absent in the primary TFC cultures. Conclusion:PRL mRNA is expressed in GD thyroid tissue. This indicates that PRL-like substance can be locally produced in GD thyroid tissue, which may play an important role in GD pathogenesis by autocrine and paracrine mechanisms.

The patients of chronic lymphocytic leukemia(CLL)have great individual differences.It is important for clinicians to determine the prognosis at the beginning of diagnosis and choose proper treatment for the patients.The recent advances in biological prognostic indicators of CLL were reviewed,including IgVH gene mutation status,ZAP70,CD_(38),chromosome abnormality[t(11q;v),del(11q),del(17p),+12 and del(13q)].telomere and telomerase.

OBJECTIVEThis study aimed to investigate the duration of gingival healing after the stage II surgery of dental implantation for periodontitis patients and to provide clinical guidelines for implant restoration.

METHODSTwenty-nine periodontitis patients who had implantation surgery and achieved osseointegration were operated with stage II surgery (a total of 60 pieces of implants). The height of buccal gingival of each implant was measured twice after the stage II surgery. All implants were measured at the lowest point ofbuccal gingival after one week. The implants were randomly divided into four groups according to the schedule of the next test time: group one at one week from the initial test point, group two at two weeks, group three at three weeks, and group four at four weeks. Each group includes 15 pieces of implants. The amount of the buccal gingival change in each group between the second and first tests was determined, and the data were analyzed statistically.

RESULTSThe amount of gingival change of groups one, two, three, and four was (-0.25 +/- 0.66), (-0.04 +/- 0.52), (-0.70 +/- 0.77), and (-0.74 +/- 1.09) mm, respectively. No significant difference was observed between groups one and two in terms of the amount of gingival changes (P > 0.05). However, a significant difference was found between groups two and three (P < 0.05), and the amount of gingival recession was 0.66 mm. No significant difference was found between groups three and four (P > 0.05), and the gingival achieved stability.

CONCLUSIONThe gingival recession achieves stability at the fourth week (after 28 d) after stage II surgery. At this time, the implant can be restored, and the abutment can be selected according to the amount of gingival change of the periodontitis patient.
