As a secreted glycoprotein,Dickkopf-1 (DKK1) is closely related to tumor metastasis,and it is highly or lowly expressed in tumor.The high expression of DKK1 promotes the metastasis of a variety of malignant tumors including liver cancer,gastric cancer,non-small cell lung cancer and breast cancer.Recent studies have found that DKK1 is inextricably bound up with the latent metastasis of tumor.

Objective To explore the effectiveness of visual feedback in retraining upper limb function after stroke.Methods Sixty-one hemiplegic stroke patients were randomly assigned to a treatment group (31 cases)which received motion training using visual feedback in addition to routine neurodevelopment treatment and a motor relearning program,and a control group (30 cases) which received only the neurodevelopment treatment and a motor relearning program.The Fugl-Meyer assessment (FMA) and the modified Ashworth scale (MAS) were used for as-sessment before treatment and after 4 weeks of treatment.Results After 4 weeks of treatment,the FMA and MAS scores of both groups had improved significantly,as had the strength of the forearm flexors.The improvements were significantly greater in the treatment group than in the control group.Conclusion Motion training with visual feed-back can alleviate upper limb spasticity after stroke significantly better than routine rehabilitation alone.

Objective To compare the effect of atropine sulphate and cyclopentolate hydrochloride in the treatment of youth hyperopia cycloplegic refraction,and provide the basis for a reasonable choice of the youth cycloplegic refraction drugs.Methods Ninety hyperopia children met inclusion criteria with refractive errors (180 eyes) were subjected to cycloplegic refratometry by 1％ cyclopentolate hydrochloride followed with 1％ atropine sulphate eye used gel.The refractive results,pupil size,residual adjustment amount and systemic side reactions were measured and compared by TOPCON.Results The coincidence rate of spherical lens degrees,cylinder lens degrees and axis of astigmatism degrees respectively was 84.44％ (152/180),92.78％ (167/180) and 92.78％ (167/180) between atropine sulphate and cyclopentolate hydrochloride.The spherical lens degrees of cyclopentolate hydrochloride was lower than atropine sulphate,the difference was statistically significant (P ＜0.01),the cylinder lens degrees and axis of astigmatism degrees had no significant difference between two drugs (P＞ 0.05).The pupil size and residual adjustment amount of cyclopentolate hydrochloride had no significant difference with atropine sulphate (P ＞ 0.05).The incidence of adverse reactions of cyclopentolate hydrochloride was 3.33％ (3/90),atropine sulphate was 13.33％ (12/90),the cyclopentolate hydrochloride was significantly lower than atropine sulphate (P ＜ 0.05).Conclusion The cyclopentolate hydrochloride has powerful,fast and secure feature in the treatment of youth hyperopia cycloplegic refraction,has good ciliary muscle paralysis effect,has longer paralysis time,as effective as the atropine sulphate,and has a shorter recovery time and better security,is ideal cycloplegic drugs for youth hyperopia cycloplegic refraction.

Objective: To develop a scale to measure attitudes toward homosexuals in Chinese university students.Methods:Based on surveys and literatures, we conducted the pre-test and test for accessing the construct validity of the scale by EFA ( exploratory factor analysis) and CFA (confirmatory factor analysis) in 1010 Chinese university students.Results: There were three components that could explain 63.84% of the total variance with loading between 0.501 and 0.851 in the scale.The three components could explain 46.67%,10.27% and 6.90% of the variance separately.They were named cognitive tolerance, emotional tolerance and behavior tolerance.The scale had NFI 0.979,NNFI 0.981,CFI 0.985,RMSEA 0.073 by CFA.The Cronbach'?coefficient was 0.931 and the test-retest reliability was 0.839 (with P

Objective To investigate the potential effect of the redox state of plasma factor Ⅺ (FXI) on the pathogenesis of elderly diabetic hypercoagulability and macroangiopathy.Methods The plasma levels of reduced FXI were detected in elderly type 2 diabetic(T2DM)patients with/without macroangiopathy (T2DM group/DMAP group) and healthy subjects (control group),and variables associated with reduced FXI were analyzed.Results Elderly patients with T2DM had higher plasma levels of reduced FXI as compared with healthy controls.The level of reduced FXI was significantly higher in patients with macroangiopathy than without macroangiopathy [control group:(80.6± 15.6) ％,T2DM group:(94.7 ± 16.0) ％,DMAP group (142.6 ± 36.5) ％,all P＜ 0.05].The multiple stepwise regression analysis showed that plasma levels of triglyceride,cholesterol and HDL-cholesterol were the independent predictors for reduced FXI.Conclusions The plasma level of reduced FXI is increased in elderly T2DM patients with macroangiopathy.The abnormality of lipid profiles may associate with the increment of reduced FXI.These findings maybe provide the novel mechanisms for diabetic hypercoagulability and macroangiopathy.

Based on the ongoing clinical experiences at our outpatient pharmacy and geriatrics multidisciplinary inpatient and outpatient services,we believe that polypharmacy among elderly patients is serious and pervasive in China.This observation is supported by the findings from literature review.To help address this serious issue in senior care,we recommend to gain better understanding of age-related physiological changes of the elderly as well as those in pharmacokinetics and pharmacodynamics,and to conduct prescription review and medication reconciliation.The multi-and interdisciplinary approach employed by modern geriatrics care model,involving doctors,pharmacists and nurses,should further help address this issue and promote rational use of pharmaceuticals in the elderly patients.

Objective: To explore the correlation of overweight, obesity and hypertension with fast resting heart rate (RHR3>100 times/min) among college freshmen in different genders, and to provide scientific reference for early prevention and control for cardiovascular disease. Methods: In September 2016, 4 362 college freshmen were measured by height, weight, blood pressure and RHR to observe the distribution of fast RHR and analyze the effects of overweight obesity and hypertension on fast resting heart rate of freshmen of different genders. Results: The detection rate of fast resting heart rate of college freshmen was 1.81%, that of male students (2.03%) was higher than that of female students (1.62%), and the difference was not statistically significant (χ2=0.99, P>0.05). fast RHR increased with body mass index (BMI) and blood pressure. After adjusting other risk factors, for male freshmen, the risk of fast RHR in overweight and obesity were 1.13 fold (95%CI：1.05-2.59) and 2.87 fold (95%CI：1.99-4.88) higher than that of the healthy people. For females, the risks were 1.34 fold (95%CI：1.11-2.85) and 3.83 fold (95%CI：2.12-8.84). In comparison to the normal blood pressure group, the ALT abnormal rate of the high blood pressure group was 15.52 fold higher in male freshmen and 17.81 fold higher in females. Conclusion Overweight, obesity and hypertension were positively correlated with fast RHR among college freshmen. Hypertensive patients have a high risk of fast RHR. Monitoring BMI and blood pressure is helpful to prevent and control cardiovascular disease.

Objective To observe the effect of adding on glimepiride in treating type 2 diabetic patients who had suffered the disease for more than 10 years and were poorly controlled with insulin combined with nonsulfonylureas drugs. Methods Seventy-five type 2 diabetic patients poorly controlled with insulin combined with non-sulfonylureas drugs were randomly divided into glimepiride-added group (INS+GM, n = 39 )and continuation of insulin group ( INS, n = 35 ). HbA1c, plasma glucose, daily insulin dose, number of hypoglycemic events, body weight, plasma lipid concentration,and high-sensitive C-reactive protein (hs-CRP)were recorded at weeks 0, 12,and 24. The levels of plasma free fatty acid ( FFA), adiponectin, and tumor necrosis factor-α ( TNF-α ) were measured before and 24 weeks after the therapy. Results At 12 and 24 weeks, fasting blood glucose, 2 h postprandial blood glucose,and HbA1c were improved in INS+GM group more markedly than in INS group, and daily insulin dose and body weight were decreased in INS+GM compared with INS ( P＜0. 05 ). The number of hypoglycemic events and plasma lipid concentration did not differ between two groups ( P＜0.05 ). The levels of plasma FFA,TNF-α,hs-CRP, and HOMA-IR were lower in INS+GM than INS ( P＜0.05 ), the adiponectin was higher in INS + GM than INS ( P ＜ 0.05 ). Conclusion Adding glimepiride to insulin therapy resulted in a sustained better glycemic control with less insulin daily dose, decresed body weight, and no increase in hypoglycemic events as compared with the continuing insulin therapy group. Increased adiponectin, as well as decreased plasma FFA and TNF-α may underlie the improvement of insulin resistance with glimepiride treatment.

Objective To assess the factors which affect the activity of isolated islets,and to construct a steady and effective isolation method of rat pancreatic islets.Methods Pancreatic islets were isolated by collagenase method.The glucose-stimulation of insulin secretion(GSIS) in different conditions was performed by batch incubation method and measured by RIA.Results GSIS was improved by BSA;There was a evident decrease of insulin secretion in cultured islets of 7 days,however,no difference was observed between the freshly isolated islets group and the 1～5days cultured islets groups.Compared to the groups of(5.5 mmol/L) and(25 mmol/L) glucose in the culture medium,(11.1 mmol/L) glucose group stimulated higher insulin release.Conclusion BSA,glucose concentration of RPMI1640 medium and the culture period are related to the activity of isolated islets.

Objective To explore the way to evaluate hemodynamics of posterior circulation distal ischemia with PWI. Methods Thirty-two patients with vertebral basilar artery severe stenosis were reviewed and compared with thirty normal persons. Information and data of PWI and MRA were collected and analyzed. Following parameters were observed, index of vascular stenosis, collateral vessels, cerebral blood flow (rCBF), cerebral blood volume (rCBV), and mean transit time (rMTT). Results All the patients had at least one vertebral basilar artery with more than 70% stenosis. There were 17 cases with severe vertebral artery stenosis , 20 cases with severe basal artery stenosis , 8 cases with severe superior cerebellar artery stenosis , 17 cases with posterior cerebral artery stenosis , 22 cases with after the traffic artery open , 11 cases with soft meningeal arteries show and 12 cases with small artery show. The ratio of ROI with frontal white matter was lower than the rCBF and rCBV in the country group. MTT value was extended and P value of the parameters in both groups was less than 0.05, reflecting the statistical difference. Conclusions PWI combined with MRA can effectively evaluate the posterior circulation distal ischemia area and tissue perfusion , as well as the hemodynamic status of ischemia area.
