Spasticity is a common complication of stroke.It may cause the function and ability of patients to be restricted significantly and affect the quality of life of both patients and their caregivers.The estimated prevalence of poststroke spasticity (PSS) is 19％ to 42.6％.PSS can be usually assessed by the Modified Ashworth Scale,Modified Tardieu Scale,and electromyography.Therapeutic methods of PSS include physical therapy and drug treatment.The treatment options should be individualized.

Objective To evaluate the diagnostic value and limits of 64-slice spiral coronary artery imaging,by com- parison with selective coronary angiography,in detection of coronary heart disease.Methods Fourty-two patients sus- pected CAD were performed 64-slice spiral CT coronary imaging and selective coronary artery angiography in two weeks, comparative analysis of results were progressed consequently.Results The sensitivity,specificity and positive and nega- tive predictive value to identify≥50% stenosis branches was 90.5%,96.6%,85.9% and 97.8%,respectively.The sen- sitivity,specificity and positive and negative predictive value to identify≥75% stenosis branches was 93.5%,98.9%, 87.9% and99.4%,respectively.Conclusion As a noinvasive quantitative assessment of coronary artery stenoses exami- nation,64-slice spiral CT is a valuable method to detect and diagnose the disease of coronary artery,but its clinical use maybe presently be limited due to image quality in a number of cases.

Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.

Objective Type 2 diabetes mellitus ( T2DM) as a common disease around the world becomes a great threat to the health of human beings.The cynomolgus T2DM model, which preferably simulates human T2DM onset and progress, can be beneficial to the drug development and clinical treatment.In the present study, 37 of T2DM-susceptibility SNPs and the extended genome sequences were used to obtain corresponding SNPs in the T2DM cynomolgus monkeys. Methods Firstly, DNA pool screening was conducted.Then, using polymerase chain reaction to amplify and to sequence the cynomolgus homologous sequences.Using DNAStar software to analyze the differences between bases.Finally, we used analysis of variance and F test to calculate the frequency of alleles.We also used the GLM models of SAS software to analyze the association of genotype with fasting plasma glucose and glycosylated hemoglobin.Results SNP661A,SNP661B, SNP343A, SNP343B, SNP343C, SNP565A, SNP565B and SNP565C were found to have a significant difference of allele frequencies between spontaneous cases and controls.Conclusions The findings of this study suggest that SNP661A, SNP661B, SNP343A, SNP343B and SNP343C may play an important role in the establishment of cynomolgus T2DM models.

Objective To explore the molecular mechanisms of primary amenorrhea by using arrayCGH technology. Methods Ten patients with primary amenorrhea and 10 female volunteers with regular menstrual cycles as healthy controls were selected. All patients and control samples were analyzed by conventional chromosome analysis (G-banding technology) and array-CGH technology, respectively. ArrayCGH was performed using Affymetrix Cytogenetic 2. 7M arrays following the manufacturer's standard protocol. Results Both the patient group and control group analyzed by conventional G-banding karyotype technology showed a negative result with a normal female karyotype: 46, XX. The result of array-CGH analysis demonstrated a microdeletion of approximately 110 000 bp located at the end of the short arm of X chromosome [46, X, del (X) (p22. 33 )] were identified in 5 patients, which was not detected in the control group. All healthy control samples by array-CGH analysis showed no pathological DNA copy number variation. Conclusions Array-CGH technology can improve the diagnosis rate of chromosomal disease at the DNA level. It is necessary to provide array-CGH for higher resolution genetic analysis of idiopathic primary amenorrhea patient who can not be identified by conventional technology.

Objective To explore the gray matter changes in aggressive patients with schizophrenia,and the relationship between the gray matter and aggression in patients.Methods Eighteen aggressive patients with schizophrenia (SZ1),18 age-and gender-matched un-aggressive patients with schizophrenia (SZ2) and 18 normal controls (NC) were enrolled in the study.Then a 3.0 T magnetic resonance imaging (MRI) scan was conducted for each participant.The voxel-based morphometry (VBM) approach and the Chinese version of Buss & Perry aggression questionnaire (B&P) were used to explore imaging data and to assess the aggression,respectively.Results Compared with NC,patients with schizophrenia showed changes in gray matter volume (GMV) in the frontal,temporal and the occipital lobes (P＜0.05,AlphaSim corrected).Compared with SZ2,SZ1 showed increased GMV in the right supramarginal gyrus,right postcentral gyms,bilateral insula and orbito-frontal gyri (P＜0.05,AlphaSim corrected).The GMV of the right insula,right postcentral gyms and right supramarginal grus were positively associated with B&P scores in patients with schizophrenia (P＜0.01,AlphaSim corrected),respectively.Conclusions These preliminary findings support that the aggression in schizophrenia is associated with GMV changes of brain regions in patients with schizophrenia.The right postcentral gyrus,the right insula and the right supramarginal gyrus may be involved in the neural mechanism of aggression in schizophrenia.

BACKGROUND: Tumor necrosis factor-associated protein 1 (TRAP1) is a heat-shock protein 90-related mitochondrial chaperone. Accumulative evidence has demonstrated that TRAP1 overexpression is closely related to carcinogenesis. However, the exact function and mechanism of TRAP1 in the occurrence of laryngeal carcinoma remains unclear. OBJECTIVE: To investigate whether RNA interference can inhibit TRAP1 overexpression and to explore its effects on growth and apoptosis of CD133+CD44+ laryngeal carcinoma stem cells. METHODS: CD133+CD44+ laryngeal carcinoma stem cells were sorted from human laryngeal carcinoma Hep-2 cellsusing immunomagnetic beads. The shRNA sequence of TRAP1 was designed and synthesized and CD133+CD44+ laryngeal carcinoma stem cells were transfected with LipofectamineTM 2000. Cell counting kit-8 assay, colony formation assay and flow cytometry were used to investigate the effects of interference of TRAP1 expression on growth and apoptosis of CD133+CD44+ laryngeal carcinoma stem cells. Spectrophotometric method was used to detect the activity of caspase-3, -8 and -9. RESULTS AND CONCLUSION: TRAP1 mRNA and protein expression levels were significantly decreased in TRAP1 shRNA-transfected CD133+CD44+ laryngeal carcinoma stem cells (P < 0.01). Compared with the blank control and negative control groups, the growth and colony formation of CD133+CD44+ laryngeal carcinoma stem cells were significantly inhibited in the TRAP1 shRNA-transfected group (P < 0.05). Apoptosis of CD133+CD44+ laryngeal carcinoma stem cells was significantly inhibited in the TRAP1 shRNA-transfected group as compared with the blank control and negative control groups (P < 0.05). TRAP1 shRNA-mediated cell apoptosis was associated with the activation of caspase-3, -8 and -9. These results suggest that RNA interference targeting inhibition of TRAP1 suppresses cell growth but promotes apoptosis in CD133+CD44+ aryngeal carcinoma stem cells. TRAP1 is likely to be a gene target for treatment of laryngeal carcinoma.
