Objective To study the etiology,clinical features and prognosis of cardiogenic cerebral embolism.Methods Cardiogenic cerebral embolism patients in the ward of Department of Cerebral vessels from April 2007 to December 2007 were registered prospectively,and then the clinical data of the patients after 3 months follow-up were analyzed.Results 72 patients were included,49 patients had atrial fibrillation.At the end of the 3 month-follow-up,15 patients were dead,the total mortality was 20.8%.25 patients must depend on others to live on.Conclusion Atrial fibrillation was the most common etiology of cardiogenic cerebral embolism.Internal carotid artery systerm was easier to form embolism than vertebrobasilar systerm.Compared with vertebrobasilar systerm,internal carotid artery systerm was much worse on nerve function impairment and prognosis.Positive measures must be taken to prevent and treat primary cardiopathy,and reduce the rate of cardiogenic cerebral embolism.

Objective To investigate the relationship between blood pressure(BP) and prognosis in three different ischemic stroke subtypes.Methods The consecutive patients with a brain infarction proven on diffusion-weighted MRI who were hospitalized within 48 hours after stroke onset between April 2007 and April 2008 were registered.All subjects with acute ischemic stroke consecutively admitted to the neurological wards of the First Affiliated Hospital of Wenzhou Medical College,were registered in the Wenzhou Stroke Registry Program.Data were collected and coded at primary registration.The BP levels were studied during the initial 7 hospital days.Survival and dependency were assessed at 3 months.Outcomes were adjusted age,consciousness level,admission NIHSS score,the decline level of systolic BP,the decline level of diastolic BP,complication and so on. Logistic regression model was used to estimate the relationship between BP and prognosis.Results A U-shaped effect was observed in each subgroup between BP and prognosis.In the subgroups of atherothrombosis,cardioembolism and small artery disease,those who had a BP of 150/95 mm Hg(1 mm Hg=0.133 kPa)on admission,140/90 mm Hg on day 1-7 would have a better prognosis.In the subgroups of atherothrombosis and cardioembolism,the decrease of BP during the first 24 hours was the independent predictor of the death and disability at 3-month.In the atherothrombosis group,when the decrease of systolic BP during the first 24 hours was greater than 20 mm Hg,the risk of the death and disability at 3-month increased 4.44 times(OR 4.44,95%CI 1.70-11.59,P=0.002).In the atherothrombosis group,when the decrease of diastolic BP during the first 24 hours was greater than 10 mm Hg,the risk of the death/disability at 3-month increased 3.70 times(OR 3.70,95%CI 1.54-8.90.P=0.00).In the cardioembolism group,the risk increased respectively 7.98 times(OR 7.98,95%CI 1.34-47.66.P=0.026)and 6.68 times(OR 6.68.95%CI 1.55-28.79,P=0.01).In the subgroups of small artery disease,the decrease of BP during the first 24 hours was not the independent predictor of the death and disability at 3-month.Conclusions A U-shaped effect is observed in each subgroup between BP and prognosis.In the subgroups of atherothrombosis and cardioembolism,the decrease of BP during the first 24 hours is the independent predictor of the death and disability at 3-month.

Objective To explore the pathogens and clinical characterization of hand,foot and mouth disease (HFMD)in Huzhou city from 2013 to 2014. Methods All 253 specimens included 208 stool specimens and 45 throat swabs,and clinical data from 208 children cases with hand,foot and mouth diseases (HFMD)were collected. Preliminary de-tection for all of the specimens was performed by one-step triple real-time RT-PCR assay. Results Real-time RT-PCR assay indicated that the positive rate of Enterovirus(EV)from 208 cases was 83.17%(173/208),and the percent-ages of EV71,CoxA16 and other's EV subtypes in 173 enteroviruses were 55.49%,13.29%and 31.21%,respectively. These results were not significant differences between male and female children. EV71 from children with HFMD was predominant strain below 5 old years (≤5),and other's EV subtypes were predominant strains over 5 years (>5). Of fever with herpes was main clinical symptom in patients with HFMD,and EV71 was primary enterovirus induced many clinical features, such as fever with herpes or vomiting or neurological symptoms and so on. Additionally, detection rate of EV in stool specimens was significant higher than that in throat swabs. Conclusion EV71 and other's EV sub-types are predominant strains, CoxA16 strains have a downtrend in patients with HFMD in Huzhou city, so that the medical workers should improve the ability of surveillance to EV,EV71 and CoxA16 in order to make better for control and prevention of the HFMD diseases.

BACKGROUND/OBJECTIVES: The association between tea consumption and risk of coronary heart disease (CHD) remains controversial. This study aimed to determine whether tea consumption has an effect on CHD risk in Chinese adults. SUBJECTS/METHODS: In this hospital-based case-control study, 267 cases of CHD and 235 non-CHD controls were enrolled. Blood samples from all cases were examined. Cardiac function indices (left ventricular ejection fraction, left ventricular end-diastolic dimension, lactate dehydrogenase, and creatine kinase of the muscle or brain type), blood lipid index (high-density lipoprotein cholesterol), and blood coagulation function indices (fibrinogen and activated partial thromboplastin time) were recorded. Tea consumption of study participants was assessed by a specifically designed questionnaire. The baseline characteristics of the study populations were recorded, and CHD-related biomarkers were detected. Differences in baseline characteristics of the study participants were examined using t-tests for continuous variables and chi-squared tests for categorical variables. Unconditional logistic regression was used to measure the association between tea and CHD. RESULTS: There were significant differences in cardiac function indices, blood lipid index, and blood coagulation indices between CHD cases and controls (P < 0.05). We found tea consumption reduced CHD risk in female participants (adjusted odds ratio (OR) = 0.484, 95% CI: 0.242–0.968, P = 0.0403). Regarding the type of tea consumed, the risk of CHD was reduced in women who drank partially fermented tea (adjusted OR = 0.210, 95% CI: 0.084–0.522, P = 0.0008). Analytic results for the amount of tea consumed per unit time showed CHD risk was reduced in women who consumed 1–2 cups of tea per day (adjusted OR = 0.291, 95% CI: 0.131–0.643, P = 0.0023). A tea-drinking frequency of > 6 days/week was beneficial for CHD prevention (adjusted OR = 0.183, 95% CI: 0.049–0.679, P = 0.0112). When analyzed according to the duration of tea consumption, the risk of CHD was reduced in participants who had been drinking tea for 10–20 years (adjusted OR = 0.360, 95% CI: 0.137–0.946, P = 0.0382). CONCLUSIONS: Tea consumption is associated with a reduced risk of CHD in female but not male populations in Guangzhou.

Ischemic preconditioning (IPC) is a potential intervention known to protect the heart against ischemia/reperfusion injury, but its role in the no-reflow phenomenon that follows reperfusion is unclear. Dihydrotanshinone I (DT) is a natural compound and this study illustrates its role in cardiac ischemic injury from the aspect of IPC. Pretreatment with DT induced modest ROS production and protected cardiomyocytes against oxygen and glucose deprivation (OGD), but the protection was prevented by a ROS scavenger. In addition, DT administration protected the heart against isoprenaline challenge. Mechanistically, PKM2 reacted to transient ROS via oxidization at Cys423/Cys424, leading to glutathionylation and nuclear translocation in dimer form. In the nucleus, PKM2 served as a co-factor to promote HIF-1α-dependent gene induction, contributing to adaptive responses. In mice subjected to permanent coronary ligation, cardiac-specific knockdown of Pkm2 blocked DT-mediated preconditioning protection, which was rescued by overexpression of wild-type Pkm2, rather than Cys423/424-mutated Pkm2. In conclusion, PKM2 is sensitive to oxidation, and subsequent glutathionylation promotes its nuclear translocation. Although IPC has been viewed as a protective means against reperfusion injury, our study reveals its potential role in protection of the heart from no-reflow ischemia.
