BACKGROUND: Preclinical studies have indicated that Angong Niuhuang Pills (ANP) reduce cerebral infarct and edema volumes. This study aimed to investigate whether ANP safely reduces cerebral infarct and edema volumes in patients with moderate to severe acute ischemic stroke. METHODS: This randomized, double-blind, placebo-controlled pilot trial included patients with acute ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores ranging from 10 to 20 in 17 centers in China between April 2021 and July 2022. Patients were allocated within 36 h after onset via block randomization to receive ANP or placebo (3 g/day for 5 days). The primary outcomes were changes in cerebral infarct and edema volumes after 14 days of treatment. The primary safety outcome was severe adverse events (SAEs) for 90 days. RESULTS: There were 57 and 60 patients finally included in the ANP and placebo groups, respectively for modified intention-to-treat analysis. The median age was 66.0 years, and the median NIHSS score at baseline was 12.0. The changes in cerebral infarct volume at day 14 were 0.3 mL and 0.4 mL in the ANP and placebo groups, respectively (median difference: -7.1 mL; interquartile range [IQR]: -18.3 to 2.3 mL, P = 0.30). The changes in cerebral edema volume of the ANP and placebo groups on day 14 were 11.4 mL and 4.0 mL, respectively ( median difference: 3.0 mL, IQR: -1.3 to 9.9 mL, P = 0.15). The rates of SAE within 90 days were similar in the ANP (3/57, 5%) and placebo (7/60, 12%) groups ( P = 0.36). Changes in serum mercury and arsenic concentrations were comparable. In patients with large artery atherosclerosis, ANP reduced the cerebral infarct volume at 14 days (median difference: -12.3 mL; IQR: -27.7 to -0.3 mL, P = 0.03). CONCLUSIONS: ANP showed a similar safety profile to placebo and non-significant tendency to reduce cerebral infarct volume in patients with moderate-to-severe stroke. Further studies are warranted to assess the efficacy of ANP in reducing cerebral infarcts and improving clinical prognosis. TRAIL REGISTRATION Clinicaltrials.gov , No. NCT04475328.

Objective To identify clinical risk factors for early major adverse cardiovascular events (MACEs) following surgical correction of supravalvar aortic stenosis (SVAS). Methods Patients who underwent SVAS surgical correction between 2002 and 2019 in Beijing and Yunnan Fuwai Cardiovascular Hospitals were included. The patients were divided into a MACEs group and a non-MACEs group based on whether MACEs concurring during postoperative hospitalization or within 30 days following surgical correction for SVAS. Their preoperative, intraoperative, and postoperative clinical data were collected for multivariate logistic regression. Results This study included 302 patients. There were 199 males and 103 females, with a median age of 63.0 (29.2, 131.2) months. The incidence of early postoperative MACEs was 7.0% (21/302). The multivariate logistic regression model identified independent risk factors for early postoperative MACEs, including ICU duration (OR=1.01, 95%CI 1.00-1.01, P=0.032), intraoperative cardiopulmonary bypass (CPB) time (OR=1.02, 95%CI 1.01-1.04, P=0.014), aortic annulus diameter (OR=0.65, 95%CI 0.43-0.97, P=0.035), aortic sinus inner diameter (OR=0.75, 95%CI 0.57-0.98, P=0.037), and diameter of the stenosis (OR=0.56, 95%CI 0.35-0.90, P=0.016). Conclusion The independent risk factors for early postoperative MACEs include ICU duration, intraoperative CPB time, aortic annulus diameter, aortic sinus inner diameter, and diameter of the stenosis. Early identification of high-risk populations for MACEs is beneficial for the development of clinical treatment strategies.

OBJECTIVE To investigate the role of solute carrier family 1 member 4(SLC1A4) in platinum-based chemotherapy resistance in ovarian cancer. METHODS The expression of SLC1A4 in ovarian cancer or platinum-resistant ovarian cancer was analyzed by GEO and TCGA database analysis tools. The expression of SLC1A4 in platinum-treated ovarian cancer cell lines was analyzed by GEO database. The relation of SLC1A4 expression and overall survival(OS) or progression free survival(PFS) in ovarian cancer patients were analyzed by Kaplan Meier-plotter. Correlation between SLC1A4 gene effect and sensitivity to chemotherapeutic agents in ovarian cancer was analyzed through DepMap platform. Low expression of SLC1A4 mediates cisplatin resistance in ovarian cancer cells as verified by flow cytometry and tumor cell clone colony formation assays; prediction of microRNAs(miRNA) targeting SLC1A4 was conducted using TargetScan then validated their correlation in TCGA ovarian cancer samples. Used COREMINE tool to analyze the biological processes of SLC1A4 mediating chemoresistance in ovarian cancer. RESULTS SLC1A4 was significantly reduced in ovarian cancer patients and platinum-resistant ovarian cancer(P<0.05) and significantly correlated with OS and PFS in ovarian cancer patients(P<0.05). SLC1A4 expression was increased in ovarian cancer cells with platinum treatment. The genetic effect of SLC1A4 on ovarian cancer was positively correlated with platinum drug sensitivity. Overexpression of SLC1A4 increased cisplatin-induced apoptosis and reduced tumor cell colony formation in ovarian cancer cells. Hsa-let-7c-5p was targeted to SLC1A4 and significantly negatively correlated in samples from drug-resistant ovarian cancer patients. CONCLUSION Low expression of SLC1A4 mediates platinum drug resistance in ovarian cancer and is potentially associated with hsa-let-7c-5p regulation.

To summarize the nursing experience of a patient with cardiac resynchronization therapy defibrillator(CRT-D)implantation who was about to deplete battery due to repeated discharge after implantation and underwent left ventricular assist device implantation combined with cryoablation.Key points of care were as follows.To begin with,we actively managed arrhythmias and electric storm.Secondly,we carried refined capacity management to avoid water and sodium retention.Thirdly,we formulated personalized anticoagulation programs to reduce the risk of bleeding and thrombosis.Then,the pump line infection should be prevented as early as possible.At the whole stage,we provided psychological counseling to improve emotional state.After discharge,regular follow-up was carried out through online and offline method to ensure quality of life in the long term.After careful treatment and nursing care,23 days after surgery,the patient was discharged smoothly,and good follow-up after discharge.

Objective:To investigate effect of vitexin on macrophage polarization and its impact on tumor growth in a mouse model of prostate cancer.Methods:C57BL/6J male mice were used to establish RM-1 prostate cancer xenograft model.Mice were ran-domly divided into model group,vitexin-low,medium and high doses groups(40,80,160 mg/kg),and cisplatin group as positive control.After continuous administration for 16 days,mice were euthanized and tumor mass was measured.HE staining was performed to observe tumor morphology.Immunohistochemistry was used to detect Ki67 positive rate.Flow cytometry was conducted to measure expressions of CD86+CD11b and CD206+CD11b in tumor-associated macrophages.CCK8 assay was performed to assess cytotoxic effect of vitexin on RAW264.7 macrophages to determine suitable concentrations.RT-qPCR was used to measure mRNA expressions of M2 macrophage markers,including arginase-1(ARG-1),Fizz1 and Ym1.Results:Vitexin inhibited tumor volume and weight,induced tumor tissue necrosis,suppressed Ki67 protein expression,increased expression of CD86+CD11b+M1 macrophages,and inhibited CD206+CD11b+M2 macrophage expression in mouse tumor tissues in vivo.Vitexin at concentrations of 10～20 μmol/L showed no cyto-toxicity on RAW264.7 macrophages in vitro,and promoted expression of iNOS in IL-4-induced M2 macrophages while inhibiting CD206 expression,as well as suppressed mRNA expressions of ARG-1,Fizz1 and Ym1.Conclusion:Vitexin effectively inhibits tumor growth in a mouse model of prostate cancer,possibly by regulating M2 macrophages towards an M1 phenotype and exerting immunomodulatory effects.

OBJECTIVE To study the intervention effect and mechanism of Zhongfeng yure decoction on ischemic stroke model rats. METHODS Totally 85 rats were randomly divided into sham operation group （normal saline， n＝15）， model control group （normal saline， n＝18）， Nimodipine tablet group （positive control， 10.8 mg/kg， n＝18）， high-dose group of Zhongfeng yure decoction （20.52 g/kg， n＝17） and low-dose group of Zhongfeng yure decoction （5.13 g/kg， n＝17）， respectively. After 7 days of preventive continuous administration （once a day）， except for the sham operation group， the rats’ middle cerebral artery occlusion （MCAO） model was established by the modified suture method in other groups. After modeling， the rats in each group continued to be administered for 3 days. During experiment， general condition of the rats was observed， and the neurological function score was performed. After the last administration， the organ index was calculated， the cerebral infarction area and pathological changes of brain tissue were observed. The levels of tumor necrosis factor-α （TNF-α） and interleukin 6 （IL-6） in brain tissue and serum， and the average optical density value of caspase-3 and phosphorylated protein kinase B（p-AKT） protein in brain tissue were detected. RESULTS Three days after modeling， compared with sham operation group， the neurological function score， in brain tissue index， spleen tissue index， proportion of cerebral infarction area， the levels of TNF-α and IL-6 in brain tissue and serum， and the average optical density value of caspase-3 protein in brain tissue were significantly increased in the model control group （P＜0.05 or P＜0.01）； karyopyknosis， diffuse edema and other lesions appeared in brain tissue. Compared with the model control group， the above indexes in each administration group were improved to varying degrees. Among them， there were significant regression in brain tissue index， spleen tissue index， proportion of cerebral infarction area， TNF-α level in brain tissue and serum， and the average optical density values of caspase-3 protein and p-AKT protein in brain tissue of rats in high-dose group of Zhongfeng yure decoction （P＜0.05 or P＜0.01）. CONCLUSIONS Zhongfeng yure decoction has a certain intervention and therapeutic effect on MCAO model rats. The mechanism may be to reduce the secretion of inflammatory factors TNF-α and IL-6， down-regulate the expression of caspase-3 protein in ischemic brain tissue， up-regulate the expression of p-AKT protein， so as to protect the neurons.
