ObjectiveTo investigate the factors influencing early treatment of patients with acute stroke.Methods300 patients with acute stroke were investigated with questionnaire which including 28 factors influencing patients receiving early treatment.Results41.5% of patients were admitted within 6 hours after onset. The responses after onset, the time to the special hospital after stroke, and whether being able to describe symptoms and style of stroke correctly were independent influencing factors. Other factors such as age, sex and stroke severity had not obvious influence to admission delay.ConclusionEffective public health programs and establishment of effective emergent medical service system are measures to minimize the admission delay.

Objective To explore the relationship between plasma homocysteine(Hcy) levels and cerebral infarction.Methods 87 patients with acute cerebral infarction and 80 controls were enrolled in the study. Plasma Hcy levels were measured by high-performance liquid chromatography-fluorescence detection(HPLC-FD) technology using Baseling 810 type high-performance liquid chromatograph.Results Fast plasma Hcy levels were higher in the patient group[(15.28?4.33)?mol/L] compared with those in the control group[(11.32?3.86) ?mol/L]( P

Objective To study the relationship of plasma homocysteine (Hcy), polymorphism in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine-?-synthase (CBS) genes, and cerebral infarction in the elderly. Methods 61 elderly patients with first-ever acute cerebral infarction and 57 controls were studied. The plasma Hcy levels were measured using high-performance liquid chromatography-fluorescence detection (HPLC-FD). The polymorphism in MTHFR was determined by a polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion.CBS was determined by amplification refractory mutation system (ARMS). Results The fast plasma Hcy levels were higher in the patient group compared with those in the control group [(13.07?3.96)?mol/L vs (11.51?3.90)?mol/L, P 0.05). There were no differences in the plasma Hcy levels among the different genotypes. Conclusions The MTHFR, CBS gene mutations cannot lead to hyperhomocysteinemia in the elderly patients with acute cerebral infarction. Hyperhomocysteinemia is associated with the independent risk of cerebral infarction, however, mutations only in MTHFR and CBS cannot be ascertained to be independent risk of cerebral infarction in the elderly.

ObjectiveTo explore the relationship between plasma homocysteine (Hcy), polymorphism in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine-β-synthase (CBS), and cerebral thrombosis.Methods87 subjects with first-ever acute cerebral thrombosis and 80 controls were studied. The plasma Hcy levels were measured using high-performance liquid chromatography-fluorescence detection (HPLC-FD). The polymorphism in MTHFR was determined by a polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion and that in CBS was determined by amplification refractory mutation system (ARMS).ResultsThe fast plasma Hcy level in the patient group was (15.28±4.33)μmol/L significantly higher than that ( 11.32 ±3.86)μmol/L in the control group (P<0.001). Different genotype had different influence on the plasma Hcy levels. There were no differences in genotype frequencies or allele frequencies between the patient group and control group (P>0.05).ConclusionCommon mutations in MTHFR, CBS G919A and CBS T833C lead to hyperhomocysteinemia. Hyperhomocysteinemia, but not common mutations in MTHFR and CBS is associated with the increased incidence of cerebral thrombosis.

Objective To investigate the influences of the genetic factors on the plasma homocysteine (Hcy) level, and the relationships between the plasma homocysteine levels and the polymorphisms in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine ?-synthase (CBS) and the cerebral infarction. Methods All 87 patients with acute cerebral thrombosis and 80 controls were studied. Plasma Hcy levels were measured by high-performance liquid chromatography-fluorescence detection(HPLC-FD)from using baseline 810 high-performance liquid chromatograph. The presence of the MTHFR C677T mutation was determined by polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion, and the presence of the CBS G919A or CBS T833C was determined by amplification refractory mutation system. Results Fast plasma Hcy levels were shown higher in the patient group (15.3?4.3) ?mol/L as compared with those in the control group (11.3?3.9) ?mol/L (P

Objective To investigate the association between nutrition and peripheral artery disease (PAD) in continuous ambulatory peritoneal dialysis (CAPD) patients.Methods One hundred and two stable CAPD patients from a single center were enrolled in this cross-sectional study.Automatic ankle-brachial index (ABI) measuring system was applied to examine ABI.Patients were divided into PAD group (ABI ＜ 0.9) and non-PAD group (ABI≥0.9).Clinical data were collected.Biochemical parameters were detected.Nutritional status was evaluated by serum albumin,handgrip strength (HGS) and subjective global assessment (SGA).Logistic regression analysis was performed to estimate the association of PAD with each nutritional marker as well as other potential risk factors.Results The incidence of PAD was 23.53％ (24/102).ABI was significantly lower in patients with malnutrition as compared to those without malnutrition [(0.72 ± 0.21) vs (1.04 ± 0.14),P＜0.01].Compared with non-PAD patients,serum albumin (P ＜ 0.01),HGS (P ＜ 0.01),diastolic blood pressure (P ＜ 0.05),serum creatine (P ＜ 0.05)、blood urine nitrogen (P ＜ 0.01) were significantly decreased,but age (P ＜ 0.01),the incidence of malnutrition [SGA,P ＜ 0.01],diabetic status (P ＜ 0.01),cardiovascular disease history (P ＜ 0.01) were significantly increased in PAD patients.Logistic regression analysis showed that serum albumin (OR=0.762,95％ CI:0.611-0.948,P=0.015),HGS (OR=0.988,95％ CI:0.979-0.997,P=0.013) were independent protective factors for PAD,malnutrition [(SGA),OR=21.101,95％ CI:5.008-88.901,P＜0.01] was independent risk factor for PAD in CAPD patients.Conclusions The PAD incidence of CAPD patients in our center is 23.53％.Nutrition is independent factor associated with PAD in CAPD patients.
