BMJ Open 2021 04 1;11(4):e043415. Epub 2021 Apr 1.

Department of Neurology, Jinan University First Affiliated Hospital, Guangzhou, China

Objectives: We aimed to determine predictors of mortality within 90 days and develop a simple score for patients with mechanical thrombectomy (MT).

Design: Analysis of a multicentre prospective registry.

Setting: In six participating centres, patients who had an acute ischaemic stroke (AIS) treated by MT between March 2017 and May 2018 were documented prospectively.

Participants: 224 patients with AIS were treated by MT.

Results: Of 224 patients, 49 (21.9%) patients died, and 87 (38.8%) were independent. Variables associated with 90-day mortality were age, previous stroke, admission National Institutes of Health Stroke Scale (NIHSS), fasting blood glucose and occlusion site. Logistic regression identified four variables independently associated with 90-day mortality: age ≥80 years (OR 3.26, 95% CI 1.45 to 7.33), previous stroke (OR 2.33, 95% CI 1.04 to 5.21), admission NIHSS ≥18 (OR 2.37, 95% CI 1.13 to 4.99) and internal carotid artery or basilar artery occlusion (OR 2.92, 95% CI 1.34 to 6.40). Using these data, we developed predicting 90-day mortality of AIS with MT (PRACTICE) score ranging from 0 to 6 points. The receiver operator curve analysis found that PRACTICE score (area under the curve (AUC)=0.744, 95% CI 0.669 to 0.820) was numerically better than iScore (AUC=0.661, 95% CI 0.577 to 0.745) and Predicting Early Mortality of Ischemic Stroke score (AUC=0.638, 95% CI 0.551 to 0.725) for predicting 90-day mortality.

Conclusions: We developed a simple score to estimate the 90-day mortality of patients who had an AIS treated with MT. But the score needs to be prospectively validated.

Trial Registration Number: Chinese Clinical Trial Registry (ChiCTR-OOC-17013052).

[Manifestations of rheumatoid arthritis patients of cold syndrome and heat syndrome using wrist ultrasound].

Zhongguo Zhong Xi Yi Jie He Za Zhi 2014 Nov;34(11):1319-23

Department of Rheumatology, China-Japan Friendship Hospital, Beijing, China.

Objective: To explore distinctive manifestations of rheumatoid arthritis (RA) patients of cold syndrome and heat syndrome using wrist joints ultrasound.

Method: s Totally 65 RA patients were syndrome typed as cold syndrome (29 cases, cold-damp blockage syndrome) and heat syndrome (36 cases, damp-heat obstruction syndrome). Grey-scale synovitis, power doppler (PD) signals, tenosynovitis, and bone erosion were observed using wrist ultrasound. Distinctive manifestations of cold syndrome and heat syndrome were analyzed using wrist ultrasound.

Results: In RA patients of cold syndrome, the positive rate of synovitis, PD, tenosynovitis, and bone erosion was 51.72%, 20.68%, 51.72%, and 37.93%, respectively, while they were 97.22%, 91.67%, 75.0%, and 63.89%, respectively in RA patients of heat syndrome. Compared with patients of cold syndrome, the positive rate of synovitis, PD, and bone erosion increased in patients of heat syndrome (P < 0.01, P < 0.01, P < 0.05). There was no statistical difference in the positive rate of tenosynovitis between the two groups (P > 0.05). Compared with the cold syndrome group, there was statistical difference in the constituent ratio of synovitis, PD, and bone erosion in the heat syndrome group (P < 0.01, P < 0.01, P < 0.05), but with no statistical difference in the constituent ratio of tenosynovitis (P > 0.05). Results of the ROC curve showed that the sensitivity was 86.1% and the specificity was 62.1% in judging heat syndrome, when the total score of synovitis in two wrists was more than 1.5; the sensitivity was 80.0% and the specificity was 93.1% in judging heat syndrome, when the total score of PD in two wrists was more than 1.5.

Conclusions: Positive rates of synovitis, PD, and bone erosion were significantly higher in RA patients of heat syndrome than those of cold syndrome. Especially serious manifestations were more often seen in RA patients of heat syndrome. The total score of synovitis or PD in the two wrist joints higher than 1.5 was characteristic manifestations of heat syndrome using wrist ultrasound.

[Shenfu injection induces the apoptosis of prostate cancer PC-3 cells].

Zhonghua Nan Ke Xue 2014 Jun;20(6):539-43

Objective: To study the effect of Shenfu Injection (SF) on the apoptosis of prostate cancer PC-3 cells and its possible mechanism.

Methods: We divided prostate cancer PC-3 cells into a blank control group and three experimental groups, the latter treated with SF at 50, 100, and 200 microl/ml, respectively, for 24, 48, and 72 hours. Then we determined the proliferation of the cells by MTT assay, measured their apoptosis by Annexin V/PI flow cytometry, and detected the expression of P53 mRNA by RT-qPCR.

Results: Compared with the blank control group, the survival rates of the prostate cancer PC-3 cells in the 50, 100, and 200 microl/ml SF groups were (93.76 +/- 2.63)%, (81.21 +/- 1.80)% and (18.01 +/- 3.84)% at 24 hours, (94.67 +/-1.11)%, (78.33 +/- 2.89)% and (10.34 +/- 1.44)% at48 hours, and (91.30 +/- 0.47)%, (36.67 +/- 1.56)% and (1.33 +/- 0.32)% at 72 hours, all significantly increased in a dose- and time-dependent manner (P < 0.05). The expression of p53 mRNA was also markedly increased in all the three experimental groups at 48 hours (P < 0. 05).

Conclusion: SF can inhibit the proliferation and induce the apoptosis of PC-3 cells, which may due to its upregulation of the p53 mRNA expression.

Glycolipid metabolic status of overweight/obese adolescents aged 9- to 15-year-old and the BMI-SDS/BMI cut-off value of predicting dyslipidemiain boys, Shanghai, China: a cross-sectional study.

Lipids Health Dis 2013 Aug 28;12:129. Epub 2013 Aug 28.

Department of Child Health Care, Children's Hospital of Fudan University, Shanghai 201102, China.

Background: The prevalence of adolescents' obesity and overweight has dramatically elevated in China. Obese children were likely to insulin resistance and dyslipidemia, which are risk factors of cardiovascular diseases. However there was no cut-off point of anthropometric values to predict the risk factors in Chinese adolescents. The present study was to investigate glycolipid metabolism status of adolescents in Shanghai and to explore the correlations between body mass index standard deviation score (BMI-SDS) and metabolic indices, determine the best cut-off value of BMI-SDS to predict dyslipidemia.

Methods: Fifteen schools in Shanghai's two districts were chosen by cluster sampling and primary screening was done in children aged 9-15 years old. After screening of bodyweight and height, overweight and obese adolescents and age-matched children with normal body weight were randomly recruited in the study. Anthropometric measurements, biochemical measurements of glycolipid profiles were done. SPSS19.0 was used to analyze the data. Receiver operating characteristic (ROC) curves were made and the best cut-off values of BMI-SDS to predict dyslipidemia were determined while the Youden indices were maximum.

Results: Five hundred and thirty-eight adolescents were enrolled in this research, among which 283 have normal bodyweight, 115 were overweight and 140 were obese. No significant differences of the ages among 3 groups were found. There were significant differences of WC-SDS (p<0.001), triacylglycerol (p<0.05), high and low density lipoprotein cholesterol (p<0.01), fasting insulin (p<0.01) and C-peptide (p<0.001) among 3 groups. Significant difference of fasting glucose was only found between normal weight and overweight group. Significant difference of total cholesterol was found between obese and normal weight group. There was no significant difference of glycated hemoglobin among 3 groups. The same tendency was found in boys but not in girls. Only HDL-C reduced and TG increased while BMI elevated in girls. The best cut-off value of BMI-SDS was 1.22 to predict dyslipidemia in boys. The BMI cut-off was 21.67 in boys.

Conclusion: Overweight and obese youths had reduced insulin sensitivity and high prevalence of dyslipidemia.When BMI-SDS elevated up to 1.22 and BMI was higher than 21.67 in boys, dyslipidemia may happen.

Sufentanil postconditioning protects the myocardium from ischemia-reperfusion via PI3K/Akt-GSK-3β pathway.

J Surg Res 2012 Dec 17;178(2):563-70. Epub 2012 Jun 17.

Anesthesiology Department, First Hospital Affiliated With China Medical University, Shenyang, China.

Background: Previous studies have shown that opioid postconditioning reduces apoptosis through antiapoptotic signaling. The present study evaluated whether sufentanil could induce cardioprotection after ischemia-reperfusion (I/R) and whether the PI3K/Akt-GSK-3β pathway modulates antiapoptotic proteins in sufentanil postconditioning.

Methods: We subjected male Sprague-Dawley rats to 30 min of myocardial ischemia and 2 h of reperfusion. We randomized rats into seven groups: sham, I/R, sufentanil postconditioning (I/R+sufen), sham plus sufentanil (sham+sufen), sham plus 15 μg · kg(-1) intravenous wortmannin (PI3K inhibitor), I/R plus wortmannin, and sufentanil plus wortmannin. We induced sufentanil postconditioning with 3 μg · kg(-1) sufentanil for 3 min in the beginning of reperfusion after 30 min ischemia. We assessed hemodynamics, myocardial infarct size, number of apoptotic cardiomyocytes, total Akt and GSK-3β, phosphorylated Akt and GSK-3β, caspase-3, Bax, and Bcl-2 protein expression.

Results: The I/R+sufen group had significantly reduced infarct size compared with the I/R group (23.3% ± 9.0% versus 50.1% ± 7.4%; P < 0.05). The apoptotic index of cardiomyocytes was significantly reduced with sufentanil treatment (20.0% ± 3.5%) compared with the I/R group (47.0% ± 6.3%; P < 0.05). The I/R+sufen group reduced the expression of protein-cleaved caspase-3 and Bax, and increased Bcl-2, phosphorylated Akt, and GSK3β compared with the I/R group. Wortmannin eliminated the cardioprotection produced with sufentanil treatment.

Conclusions: Sufentanil postconditioning can induce myocardial protection by activating the PI3K/Akt-GSK-3β pathway and modulating Bax and Bcl-2 expression.

Ischemic postconditioning mediates cardioprotection via PI3K/GSK-3β/β-catenin signaling pathway in ischemic rat myocardium.

Shock 2012 Aug;38(2):165-9

Anesthesiology Department, the First Hospital Affiliated at China Medical University, Shenyang, China.

Previous studies have shown that PI3K/GSK-3β/β-catenin signaling pathway plays a vital role in ischemic preconditioning. The present study attempts to evaluate whether PI3K/GSK-3β/β-catenin signaling pathway might be responsible for the cardioprotection in ischemic postconditioning. Male Sprague-Dawley rats underwent 30 min of left anterior descending coronary artery occlusion and 2 h of reperfusion. One hundred twenty rats were randomized into six groups: sham, ischemia/reperfusion (I/R), ischemic postconditioning (Post), 15 μg · kg wortmannin (PI3K inhibitor) plus ischemic postconditioning (Wort + Post), wortmannin plus I/R (Wort + I/R), and 0.6 mg · kg SB216763 (GSK-3β inhibitor) plus I/R (SB + I/R). Wortmannin and SB216763 were administered, respectively, 10 and 5 min before reperfusion. Myocardial infarct size; number of apoptotic cardiomyocytes; total Akt, GSK-3β; phosphorylated Akt, GSK-3β; β-catenin in cytosol and nucleus; and Bcl-2 protein were assessed. It was found that Post and SB + I/R reduced infarct size (32.3% [SD, 2.8%], 32.7% [SD, 2.1%], vs. 53.4% [SD, 3.2%], respectively, P < 0.05) and apoptotic index of cardiomyocytes (23.2% [SD, 1.8%], 23.8% [SD, 1.8%], vs. 47.3% [SD, 5.8%], respectively, P < 0.05); compared with I/R, wortmannin abolished the cardioprotection of ischemic postconditioning. Post and SB + I/R increased phosphorylated Akt, phosphorylated GSK3β, β-catenin in cytosol and nucleus, and Bcl-2 expression versus I/R. These results indicate that ischemic postconditioning could induce myocardial protection via PI3K/GSK-3β/β-catenin signaling pathway, activation of which results in accumulation of β-catenin and upregulation of its target genes Bcl-2.
