Objective To explore the differential effects of stroke localization on autonomic function parameters assessed by HRV and study the circadian fluctuation of HRV in the acute phase of ischemic stroke.Methods Components of HRV were obtained twice from patients in acute stroke(5d and 4w) in 68 cases and 50 age-and sex-matched health control subjects.Cerebral CT or MRI verified hemispheric brain infarction and.Results(1) In the acute phase of ischemic stroke(5d) all components of heart rate variability had significantly decreased P

Objective To establish a simple and rapid new method for DNA extraction of FTA bloodstain samples.Methods Genomic DNA was extracted from FTA bloodstains of 1.2mm diameter by FTA-DNA direct extraction and FTA routine method respectively,and their genotypes were analyzed using ABI IdentifilerTM kit in 10?l and 25?l of reaction volume respectively.Results For 25?l of reaction volume,all DNA extracted by two different methods was successfully genotyped.For 10?l of reaction volume,however,the typing success rate of DNA extracted by FTA routine method was significantly lower than those by FTA-DNA direct extraction procedure.Using FTA routine method,the value of RFU ranged from 100 to 2000,and the peak imbalance result from preferential amplification of the smaller allele was a common phenomenon.Moreover,allelic dropout occurred in approximately nineteen percent of samples,and this was not obviously improved even if performed by automatic DNA workstation.However,using FTA-DNA direct extraction procedure,the typing results were similar to those in 25?l of reaction volume,and better results can be obtained using automatic DNA workstation.Conclusion The FTA-DNA direct extraction method is simple and rapid,and can be used to automatic establishment of DNA database with FTA bloodstains.

Objective To investigate the correlation between apolipoprotein E (ApoE)polymorphisms and cerebral infarction in Dali Bai populations in Yunnan province.Methods A total of 40 Dali Bai patients with cerebral infarction (female.23,male 17) and 43 Dali Bai normal controls (female 18,male 25) were included in the study.Polymerase chain reactionrestriction fragment length polymorphism (PCR-RFLP) analysis was used to detect APoE genotype,meanwhile the lipid levels were detected,and finally,ApoE gene sequencing was conducted.The correlation between the APoE gene polymorphism and the types of cerebral infarction were further studied.Results The frequencies of genotype ε3/ε4 (22.5% vs.4.7%,P ＜0.05) and ε4 (12.5% vs.3.5%,P ＜0.05) in the Dali Bai cerebral infarction group were significantly higher than those in Dali Bai normal control group,and the frequencies of genotype

Objective To investigate the expression of MCM2 and its prognostic significance in non-small cell lung cancer (NSCLC). Methods The expression of MCM2 was measured by immunohistochemistry in 73 cases of NSCLC and 10 cases of normal lung tissue. The correlations between the expression of MCM2 and clinic-opathological parameters and prognosis were investigated. Results There was no MCM2 expression in normal lung tissue and positive rate of MCM2 expression was 87.7% in NSCLC. The difference between the two groups was significant (P<0.001). The expression of MCM2 in poorly differentiated NSCLC patients was significantly higher than that in moderately- and well-differentiated NSCLC patients (P=0.008). The expression of MCM2 in patients with squamous carcinoma was higher than that in patients with adenocarcinoma (P=0.005). The hazard ratio was significantly higher(RR=3.389, 95 % CI=1.803-7.146,P<0.001), and the accumulated survival rate was significantly lower (P=0.001) in NSCLC patients with higher MCM2 expression than that of lower expression. MCM2 was independent prognostic factor of NSCLC patients (P=0.041). Conclusion MCM2 could reflect the reproductive activity of NSCLC and has some clinical significance for assessing the development and prognosis of NSCLC. MCM2 was a potential target for future treatment.

Objective To explore expression of the minichromosome maintenance 2 (MCM2)protein and the mucin-like cell surface adhesion molecule CD24 in non-small cell lung cancer (NSCLC) and their relationship with its prognosis. Methods Seventy-three patients of NSCLC diagnosed for the first time and received surgical treatment in Xuanwu Hospital, Beijing were selected for the study. Expression of the MCM2 and CD24 in pathological specimens of the patients was measured by immunohistochemistry and their relationship with its prognosis was analyzed retrospectively. Results High-level expression of the MCM2 and CD24 was seen in 42 and 54 of 73 NSCLC patients, accounting for 57. 5 percent and 74. 0 percent,respectively. Risk of death for the patients with high-level expression of the MCM2 or the CD4 was significantly higher as compared to those with low-level expression ( P ＜ 0. 05 ). Risk of death for patients with both high-level expression of the MCM2 and CD24 was significantly higher than that in those with only high-level expression of the MCM2 or the CD24 (HR =2. 59, 95%CI 1.40 -4. 80, P=0. 002) and in those with both low-level expression of them ( HR = 15.32, 95 % CI = 2.07 - 113.41, P = 0. 008 ). But there was no significant difference in risk of death between patients with high-level expression of the MCM2 or CD24 and those with low-level expression of both of them ( HR = 5. 60, 95% CI 0. 79 - 44. 82, P = 0. 083 ), and cumulative survival rate of patients with both high-level expression of the MCM2 and CD24 was significantly lower than those with only high-level expression of the MCM2 or the CD24 ( P = 0. 001 ). Conclusions Both expression of the MCM2 and the CD24 are independent prognostic factors for NSCLC and combined detection of the two markers have higher prognostic value for it.

Objective To detect the expressions of interleukin-11 (IL-11) and interleukin-11 receptorα(IL-11Rα) in non-small cell lung cancer (NSCLC) cell lines, and explore their clinical significances. Methods The expressions of IL-11 and IL-11Rαin NSCLC cell lines A549, H2228, healthy lung small airway epithelial cell (SAEC) line cytoplasm, cell membrane and nucleus were detected by Western blot. Results The expressions of IL-11 and IL-11Rα were low in the cell membrance and nucleus (cell membrane: IL-110.04± 0.03, IL-11Rα0.05±0.03; nuclear: IL-110.45±0.19, IL-11Rα0.07±0.02;P<0.01); The expressions of IL-11 and IL-11Rα in A549 and H2228 cell lines were significantly increased compared with those of SAEC cell lines in the cell membrance and cytoplasm (P< 0.01); Among the A549 cell lines, the expressions of IL-11 and IL-11Rα in cell nucleus were much higher than those of the cell membrance and cytoplasm (P< 0.01). Among the H2228 cell lines, the expression of IL-11 in cytoplasm was the highest and the expression of IL-11Rα was the highest in the cell nucleus (P< 0.01). Conclusion The expressions of IL-11 and IL-11Rαare high in NSCLC cell lines, and it is good for the screening and early diagnosis of lung cancer by detecting the expressions of IL-11 and IL-11Rα.
