Objective To investigate the correlation between prostacyclin synthase (prostaglandin I2 synthase, PGIS) gene rs5602 single nucleotide polymorphism and ischemia stroke in Chinese Han population. Methods The patients with ischemia stroke and healthy controls in Chinese Han population were enroled. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS) was used to detect the rs5602 polymorphism. Results A total of 297 patients with ischemic stroke (male 177 and female 120) and 291 healthy controls (male 165, female 126) over the same period were enroled. The frequencies of TT genotype (31. 1% vs. 43. 6% ; χ2 = 5. 773, P = 0. 016) and T alele (56. 8% vs. 65. 8% ; χ2 = 5. 793, P = 0. 016) in the male patients with ischemic stroke were significantly lower than those in the male healthy controls. Multivariate logistic regression analysis showed that the rs5602 TT genotype was a protective factor for ischemic stroke in male (odds ratio 0. 260, 95% confidence interval 0. 118-0. 570; P = 0. 001). Conclusions PGIS gene rs5602 polymorphism is associated with ischemic stroke in male in Chinese Han population.

Objective To study incidence of deep vein thrombosis (DVT) in the acute phase and follow-up period after stroke, and to investigate risk factors of DVT. Methods This was a prospective study at multi-centers. Ultrasonography was used for detecting DVT on both lower extremities in all patients at 10-14 days after the onset of stroke. All patients were followed up for 6 months after discharge. The incidence of DVT was examined in the acute phase and in the follow-up period of stroke. A variety of patient and treatment related factors were compared between stroke patients with DVT and without DVT to identify DVT risk factors. Results The incidence of DVT in the acute period of stroke was 4. 49%. Among DVT patients, 51.6% patients presented clinical DVT symptoms. By multiple factors logistic regression analysis,age ( ≥70 years, OR = 1.63, 95% CI 1.08-2. 84), bedridden( OR =4. 85, 95% CI 2.65-9. 68 ), wells score ≥ 2 ( OR = 3.96, 95% CI 1.86-7. 86 ), lower limbs NIHSS score ≥ 3 ( OR = 4. 56, 95% CI 2. 07-8. 85 ), high D-dimer ( OR = 3.45, 95% CI 2. 01-8. 52 ), low BI scores ( OR = 2. 98, 95% CI 1.52-6. 47 ), rehabilitation therapy ( OR = 1.82, 95% CI 1.22-3.43 ) and anticoagulant therapy ( OR =1.91,95% CI 1. 34-4. 92 ) were independent risk factors of DVT in the acute phase of stroke. Among them, the rehabilitation therapy and anticoagulant therapy were protective factors. The incidence of DVT in the follow-up periods was 1. 51%. Age ( ≥ 70 years, OR = 1.82, 95% CI 1.21-3.98 ), bedridden after discharge( OR = 5. 12, 95% CI 2. 82-11.32), lower limbs NIHSS score ≥3 ( OR = 4. 25, 95% CI 2. 11-7. 87), low BI score( OR = 2. 18, 95% CI 1.18-6.23 )at the time of discharge and DVT in acute period (OR =3.81,95%CI 1.87-7.48)were independent risk factors of DVT in the follow-up period of stroke.Conclusions Stroke patients, particularly old-aged stroke patients, are a high-risk group of developing DVT. 48.4% DVT patients had no clinical DVT symptoms but were diagnosed only by ultrasonography.There are multiple independent risk factors of DVT after stroke. It is necessary to monitor and prevent DVT in the stroke patients with the risk factors. The rehabilitation therapy and anticoagulant therapy may decrease incidence of DVT.

Objective To analyze the differences in microRNA (miRNA) expression between A549 and A549/DDP cells and explore the association between miRNA expression and drug resistance in non-small cell lung cancer (NSCLC).Methods The drug resistance of A549/DDP cells was evaluated using CCK-8 assay and flow cytometry.Microarray technique and RT-PCR were used to analyze the differential expression of the miRNA between A549 and A549/DDP cells.Enforced or inhibited target miRNA expression in cisplatin resistant cell was used to investigate whether miRNA involve in modulating the sensitivity of NSCLC cells to chemotherapeutic agent,exploiting the emerging knowledge of miRNA for the development of new human therapeutic applications for overcoming anticancer drug resistance and trying to discover biomarkers that were better able to predict the cancer chemotherapy sensitivity.Results The drug resistance index of A549/DDP cells relative to the parental A549 cells was 18.Microarray analysis of A549 and A549/DDP cells identified 51 differentially expressed genes (≥4-fold),including 24 up-regulated and 27 down-regulated genes in A549/DDP cells.RT-PCR identified 9 miRNA that were differentially expressed between A549 and A549/DDP cells.Of these differentially expressed miRNA,miR-376c,miR-31,miR-29a,miR-221 showed significantly increased expression,and miR-196a,miR-20a,miR-20b,miR-17,miR-451 showed significantlylowered expression in A549/DDP cells as indicated by the results of microarray analysis and RT-PCR.DDP sensitivity was increased 11.7 ％ in A549/DDP cells transfected with miR-17,but the chemosensitivity was decreased when miR-451 was over-expressed or miR-29a was inhibited by selective inhibitor,the reduction was 15.5 ％,12.9 ％,respectively,whereas chemosensitivity did not change when miR-376c,miR-31,miR-221 were inhibited or miR-196a,miR-20b,miR-20a were over-expressed.Conclusion A549/DDP cells show a different miRNA expression profile from its parental A549 cells,suggesting the involvement of miRNA in tumor cell drug resistance.miR-17 has the potential to be an efficient agent for preventing and reversing DDP-resistance in NSCLC.These results provide a strong rationale for the development of miRNA-based therapeutic strategies aiming to overcome cancer cell resistance.

Objective To evaluate the effectiveness of biofeedback in preventing chronic daily headaches. Methods One hundred patients experiencing daily headaches were randomly divided into a biofeedback group ( n=50) and a drug therapy group (n=50). The patients in the drug therapy groupwere administered a predetermined course of medication. Those in the biofeedback group were given 30 minutes of biofeedback therapy twice a week for 8 weeks, followed by 10 months of intensive therapy once a month. The headache frequency, duration of headache at-tacks, days of using acute pain medication and any other adverse events were recorded 3, 6 and 12 months after the treatment. Results The patients in the biofeedback group had significantly less-frequent headaches, shorter headache attacks and fewer days of using acute pain medications. Conclusion Compared to drug therapy, biofeed-back can prevent chronic daily headachesmore safely and effectively.

BACKGROUND AND PURPOSE: Dual antiplatelet therapy (DAT) with clopidogrel and aspirin has been shown to confer greater protection against early neurological deterioration (END) and early recurrent ischemic stroke (ERIS) than aspirin alone in patients who have experienced an acute ischemic stroke. However, few studies have compared the effects of anticoagulation therapy with low-molecular-weight heparin (LMWH), DAT, and aspirin. METHODS: Patients with acute ischemic stroke (n=1,467) were randomized to therapy groups receiving aspirin (200 mg daily for 14 days, followed by 100 mg daily for 6 months), DAT (200 mg of aspirin and 75 mg of clopidogrel daily for 14 days, then 100 mg of aspirin daily for 6 months), or LMWH (4,000 antifactor Xa IU of enoxaparin in 0.4 mL subcutaneously twice daily for 14 days, followed by 100 mg of aspirin daily for 6 months). The effects of these treatment strategies on the incidence of END, ERIS, and deep-vein thrombosis (DVT) were observed for 10-14 days after treatment, and their impacts on a good outcome were evaluated at 6 months. RESULTS: The DAT and LMWH were associated with a more significant reduction of END and ERIS within 14 days compared with aspirin-alone therapy. In addition, LMWH was associated with a significantly lower incidence of DVT within 14 days. At 6 months, DAT or LMWH improved the outcome among patients aged >70 years and those with symptomatic stenosis in the posterior circulation or basilar artery compared with aspirin. CONCLUSIONS: LMWH or DAT may be more effective than aspirin alone for reducing the incidence of END and ERIS within 14 days, and is associated with improved outcomes in elderly patients and those with stenosis in the posterior circulation or basilar artery at 6 months poststroke.

Objective To assess the anti-arrhythmic activity and cardioprotective effects of Wenxin Granula, a traditional Chinese formula (consisting of Salviae Miltiorrhizae Radix, Polygonati Rhizoma, Notoginseng Radix et Rhizoma, Nardostachyos Radix et Rhizoma, Angelicae Sinensis Radix, and Succinum), on heart in ischemic-induced myocardial infarction (MI) rats and compare with those of Amiodarone which have been demonstrated in clinic. Methods Rats were randomly divided into Sham-operated (control), Ml + Amiodarone [5 mg/(kg·d)] (MI), and MI + Wenxin Granula [10 mg/(kg·d)] groups and left anterior descending coronary artery was occluded in each group. After left anterior descending for 12 h, standard lead Ⅱ of administration electrocardiogram was recorded in order to analyze the occurrence of arrhythmia. After one month, the size of the infarct area of heart was evaluated by TTC staining method and haemodynamic function was assessed to detect the heart function. Laser scanning confocal microscope and the technique of patch clamp were used to detect the intracellular Ca2+ ([Ca2+]j) and L-type calcium current (ICa-L), respectively. Results Both Wenxin Granula [10 mg/(kg·d)] and Amiodarone [5 mg/(kg·d)] could markedly decrease the incidence of arrhythmia in heart of rats which were subjected to ischemic injury. After one month, Wenxin Granula could significantly decrease mortality to 22.22% and reduce the infarct area (P < 0.05), but Amiodarone did not. The mechanism may involve that Wenxin Granula attenuated [Ca2+]j decreasing in MI rats. Additionally, Wenxin Granula could obviously ameliorate the impaired heart function of MI rats by decreasing the elevated left ventricular end-diastolic pressure and increasing the attenuated maximum change velocity of left ventricular pressure in the isovolumic contraction or relaxation period. On the other hand, electrophysiological experiment results revealed that Wenxin Granula administration one month later also increased the reduced ICa-L density in rat ventricular myocytes in MI rats. The results of LSCM showed that Wenxin Granula could recover the amplitude of [Ca2+]j decreased by heart failure during long term. Conclusion Wenxin Granula could not only inhibit the incidence of arrhythmia but also decrease the mortality, which was accompanied by recovering the amplitude of [Ca2+]j. This protective effect of Wenxin Granula may partially be mediated through changing ICa-L.as well as increasing [Ca2+]j.

Objective:To explore the predictive value of regional leptomeningeal collateral circulation scale (rLMC) based on multimodal CT in recanalization of blood vessels in patients with acute ischemic stroke after thrombectomy.Methods:A retrospective analysis was conducted on clinical data of patients with acute ischemic stroke within 6 h of first onset, admitted to our hospital from October 2017 to December 2019. Before operation, the conditions of their vessels were evaluated by rLMC based on multimodal CT. Two areas, anterior cerebral artery (ACA)-middle cerebral artery (MCA) area and posterior cerebral artery (PCA)-MCA area, were divided. The total rLMC scores of two areas (0-10) were calculated: scores of 0-3, scores of 4-7, scores of 8-10. After admission, the recanalization of the blood vessels after thrombectomy was evaluated immediately according to grading of thrombolysis in cerebral infarction (TICI) after completion of thrombectomy within the time window; TICI grading≥II was defined as succeed recanalization. The correlation between rLMC scores and vascular recanalization in patients with acute ischemic stroke was evaluated.Results:Among the 80 patients, 17 were in the rLMC scores of 0-3 group, 25 in the group of rLMC scores of 4-7, and 38 in the group of rLMC scores of 8-10; 68 patients (85.00%) had vascular recanalization, and the success rate of vascular recanalization in patients from the group of rLMC scores of 8-10 was significantly higher than that in the group of rLMC scores of 0-3 (97.36% vs. 58.82%, P<0.05). Correlation analysis results showed that the rLMC score was positively correlated with success rate of vascular recanalization ( r s=0.625, P=0.000); whose sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 89.5%, 90.9%, 94.45%, 83.3% and 90.0%, respectively. Conclusion:The rLMC is closely related to the recanalization rate in patients with acute ischemic stroke after thrombectomy; the success rate of recanalization after intravascular treatment is relatively high in patients with rLMC scores of 8-10.
