Objective To investigate the incidence and relative factors of post-stroke depression (PSD). Methods 520 patients with stroke were assessed by 17-item Hamilton Depression Rating Scales (HAMD). A self-designed register form was analysed in 520 stroke survivorsA multiple factor analysis with the logistic regression method was carried out on the basis of these data. Results Among them, 178 cases (34.2%) were identified as depression. The minor, moderate and major incedenses were 20.2%, 10.4% and 3.7% respectively. In addition, stepwise regression analysis shows that important risk factors involved in PSD contained depression history, sex, family harmony, accompanying disease, neurological deficit and stoke course. Conclusion The factors above were the major predictive factors and useful for PSD prevention

Objective: To study the influence of PSD (post-stroke depression) on early restore Method: 67 patients with acute stroke were evaluated with HAMD and NFA (neurological function assessment) They were followed for 6 months after discharge Results:The rate of PSD was 37%, most in mild to moderate levels Patients with PSD stayed longer in hospital than those without In follow up, patients with PSD had poor outcome in NFA Conclusion: PSD has negative influence on restore of stroke

Objective To evaluate the effects of delayed transplantation of bone marrow mononuclear cells (BM-MNCs) after myocardial infarction (MI) on the expressions of bcl-2/bax mRNA and proteins in myocardial cells, and to explore the possible mechanism of cardiomyocyte apoptosis. Methods The MI rat model was reproduced by ligating the left anterior descending coronary artery. Two weeks later 5?106 of BM-MNCs were injected into the infarct zone and the peri-infarct zone (BMT group). TUNEL was used to determine the cardiomyocyte apoptosis, immunohistochemical method was employed to detect the expressions of bcl-2 and bax protein, and the technique of hybridization in situ was applied to assess the changes in of bcl-2/bax mRNA expression. Results TUNEL results indicated that apoptosis index of BMT group was lowered significantly compared with the control group (4 weeks: 0.095?0.017 vs 0.173?0.018; 8 weeks: 0.0916?0.014 vs 0.182?0.015, P

Cerebral autosomal dominant arteriopathy with subcortical infarcts and lecukoencephalopathy (CADASIL) is a recently described neurovascular disease affecting young to middle aged individuals. The disease is caused by mutations in the Notch3 gene located in the long arm of chromosome 19. The disease clinically is characterized by migrainous headaches ,mood disturbances, focal neurologic deficits, transient ischemic attaches, strokes and dementia. Pathologically, the disease is characterized by a stereotypic degeneration of the arterial walls with deposition in the media of a nonatheromatous,(nonamyloidotic) substance that under the electron microscope (EM) appears as a granular osmiophilic material (GOM). A review of current literature is presented concerning the clinical, radiological, pathologic and genetic feature of CADASIL.

OBJECTIVE: To make an useful identification method for the molecule of DNA on 3 herbs of Artemisia genus and compare the differences of the genes of Korean and Chinese species of Artemisia. METHODS: Sequence of 3 herbs (Artemisia sacrorum Ledeb., Artemisia iwayomogi Kitam. and Artemisia capillaris Thunb.) was determined by PCR sequence system. DNA was extracted from rDNA/ITS (internal transcribed spacers) and 5.8 s. The analysis was based on the amplification through DNA sequence system. RESULTS: There were profound differences between the Korean Artemisia and Artemisia sacrorum L. These 2 herbs had a difference in the PCR amplifications of the agarose gel electrophoresis. There was a slight difference in the analysis of the DNA sequence system, and the substitution percentage for ITS gene fragments sequence was 3.96%. CONCLUSION: Analytic identification method on sequence system of ITS in rDNA is effective for these 3 herbs.

Objective To explore the value of placental alpha-microglobulin-1 in vagina liquid to diagnose premature rupture of membranes. Methods A prospective observational study to initial evaluation included both the standard clinical evaluation for rupture of membranes and placental alpha-microglobulin-1 immunoassay. Rupture of membranes was diagnosed if fluid was seen leaking from the cervical os or if two of the following three conditions were present: pooling of fluid, positive nitrazine test, or feming. Rupture of membranes was diagnosed definitively on review of the medical records after delivery. Results Placental alpha-microglobulin-1 immunoassay confirmed rupture of membranes at initial presentation with a sensitivity of 100% (89/89), specificity of 91% (10/11), positive predictive value of 99% (89/90), and negative predictive value of 100% (10/10),false positive rate of 9% (1/11). Placental alpha-nricroglobulin-1 immunoassay was better than the conventional clinical assessment in confirming the diagnosis of rupture ofmembranes (P<0.01). Conclusion Measurement of placental alpha-microglobulin-1 in cervicovaginal secretions is superior to conventional clinical assessment in the diagnosis of rupture of membranes.

Objective To investigate the relationship between post-stroke pathological laughing and crying and depression.Methods Among 276 stroke patients in hospital,28 patients with pathological laughing and crying were chosen as PLC group,and other 28 patients matched with gender and age but without PLC were choosen as the control group.All patients were investigated with Hamilton Depression Scale(HAMD),PLC scale and clinical features.Results There was no significantly difference(P>0.05)in total and factor scores of HAMD between these two groups.Conclusion The pathological laughing and crying and depression seem to result from different pathogenesis.

In the previous study, a high-throughput screening method was established to find the antagonists of CD36. In the present study, a new compound named IMB-1680 was found using this method. The anti-atherosclerotic activities of IMB-1680 were then evaluated. Dose-dependent activities of IMB-1680 were detected by using Sf9 [hCD36] and CHO [hCD36] models. Fluorescence microscopic photography and flow cytometry were used to analyze uptake of mLDL. Foam cell test with RAW264.7 macrophages was used to examine lipid accumulation. The results showed that IMB-1680 inhibited CD36 activity with IC50 of 2.80 and 8.79 micromol x L(-1) in Sf9[hCD36] and CHO [hCD36] cells, respectively. Fluorescence microscopic photography and flow cytometry revealed that IMB-1680 could significantly reduce DiI-AcLDL uptake. Meanwhile, IMB-1680 also could reduce lipids accumulation in RAW264.7 macrophages. In all, the data indicated that IMB-1680 might be a potent effective anti-atherosclerotic leading compound.

Background and purpose: The Writ cell-signaling pathway is the key cellular developmental pathway. Dysregulation of this pathway has been implicated in the initiation and progression of cancer. Adenomatous polyposis coli (APC) is an important tumor suppressor gene of the Writ signaling pathway. The methylation of APC promoter and the accompanying loss of the APC transcript have been shown to occur in a significant proportion of cancers. However, there are few reports on the relationship between cervical cancer and methylation of APC. This study was aimed to investigate the promoter methylation status of the APC genes in cervical cancer and its correlation between clinicopathologic characteristics and the infection of high-risk HPV DNA. Methods: Promoter methylation was evaluated using a MSP (methylation-specific polymerase chain reaction) in 95 cervical cancer tissue specimens and 20 normal controls. The relationship between clinicopathologic parameters and the methylation status was evaluated. Results: The frequencies of promoter methylation of APC in cervical cancer were 56.8%. Cervical cancer had significant higher methylation frequencies than that of the controls (10%, P<0.01). The result showed that the methylation analysis of APC promoter and high-risk HPV DNA testing had good consistency (Kappa=0.348, P<0.001). The promoter methylation of APC was significantly higher in adenocarcinoma (AC) than in squamous cell carcinoma (SCC) (74.1% vs 50.0%, respectively, P<0.05). The larger tumor size, positive lymph node metastasis and positive HPV DNA exhibited an increased promoter methylation frequency for APC (P<0.05). There were no significant associations between the methylation frequencies for APC gene to age, invasion depth, FIGO stage and histological grade. Conclusion: Our results suggested that the promoter methyiation of APC and high-risk HPV DNA testing had good consistency. APC gene promoter methylation was a frequent epigenetic event in cervical carcinoma and had a significant correlation with cancer pathological types.

Objective To explore the high-risk prognostic factors of patients with cervical cancer Methods To collect the clinical datas and follow-up visit results of patients, 365 cases of cervical cancer were retrospectively analyzed. To use Kaplan-Meier methods to calculate survival rate and use the Log-rank test to compare the significant difference between different survival curves. Based on the univarite survival analysis, COX proportional hazards regression model was adopted to analyze the risk prognostic factors.Results The 5-year, 10-year, 15-year and 20-year survival rates were 88 %, 83 %, 81% and 80%,respectively. In univariate survival analysis, there was significant differents between the survival curves of age and clinical stage (x2 = 19.738, P ＜0.01 and x2 = 36.672, P ＜0.01). And the survival rate of the higher age group was higher than the lower age group, the group of lower clinical stage was higher or equal to the group of higher clinical stage. In the COX regressive analysis, clinical stage and age were relevant to the prognosis of cervical cancer (P ＜0.01). Conclusion Age and clinical stage are prognostic factors of cervical cancer. Early diagnosis and treatment is still the main means to lower the rate of death resulted from the cervical cancer.
