To study the effect of Furong Tongmai capsule combined with valsartan in protecting the target organ injury in patients with essential hypertension. From May 2022 to April 2023, 92 patients with essential hypertension admitted to Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine in Hebei Province were divided into the placebo group (46 cases) treated with valsartan combined with placebo and the Furongtongmai group (46 cases) treated with valsartan combined with Furongtongmai capsule. The grouping method was random lottery, and all patients were treated for 12 weeks. The curative effects of the two groups after 12 weeks of treatment were counted, and the levels of serum cytokines, blood pressure control, cardiac and renal functions, carotid artery and cerebral blood flow were compared before and after 12 weeks of treatment. After 12 weeks of treatment, the total effective rate of the Furongtongmai group was higher than that of the placebo group (P<0.05). After 12 weeks of treatment, the levels of serum homocysteine (HCY), myeloperoxidase (MPO), high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor -α(TNF-α), serum creatinine (SCr), urinary microalbumin (mAlb), β2-microglobulin (β2-MG), diastolic pressure, systolic pressure and mean nocturnal diastolic pressure in the two groups. Left atrial diameter index (LADI), left ventricular mass index (LVMI), intima-media thickness of common carotid artery (CCA-IMT), intima-media thickness of internal carotid artery (ICA-IMT) and the number of carotid plaques decreased compared with those before treatment, and the Furongtongmai group was lower than the placebo group (P<0.05). Left ventricular ejection fraction (LVEF), average blood flow velocity of left vertebral artery, right vertebral artery and basilar artery were higher than before treatment, and the Furongtongmai group was higher than the placebo group (P<0.05). Furongtongmai Capsule combined with valsartan could regulate the level of serum cytokines in patients with essential hypertension, improve their heart and renal function, carotid intima-media thickness, increase cerebral blood flow velocity, relieve target organ injury, and had a good target organ protection effect and good curative effect [ABSTRACT FROM AUTHOR]

Objectives: Spaceborne global navigation satellite system-reflectometry （GNSS-R） has been demonstrated to be effective in retrieving global sea surface wind speed, and many missions have been launched in orbit or planned. “Jilin-1” Kuanfu-01B satellite, as a commercial remote sensing satellite of China, equipped a GNSS-R instrument to observe Earth's physical parameters. This paper aims to preliminarily analyze and demonstrate the effectiveness and feasibility of GNSS-R data from “Jilin-1” Kuanfu01B satellite for retrieving sea surface wind speed. Methods: Three basic observables sensitive to wind speed, namely the delay-Doppler map (DDM) peak signal-to-noise ratio (SNR), the leading-edge slope and trailing-edge slope of the normalized delay waveform, are extracted from the DDMs of “Jilin-1” Kuanfu-01B satellite, and are used to demonstrate and assess the potential in retrieving wind speed. Three basic observables have obvious inversely proportional relationships with wind speed; therefore, an empirical exponential function is used to develop the geographic model function (GMF) between the basic observables and wind speed. Furthermore, the root mean square error (RMSE) between the retrieved wind speeds and European Centre for Medium-Range Weather Forecasts (ECMWF) data are obtained. Results: The RMSE of the retrieved wind speed using DDM peak SNR, leading-edge slope and trailingedge slope are 3.22 m/s, 3.67 m/s and 3.49 m/s without data quality control and data calibration. When SNR is controlled to be larger than −6 dB, the RMSE of the retrieved wind speed using the DDM peak SNR reduces to be within 2 m/s, and the useful data are 78.11 % of that without data quality control. For leading-edge slope and trailing-edge slope, when SNR threshold is −3 dB, the RMSE of retrieved wind speed is also decreased to be within 2 m/s, and the useful data reduce to 53.74 %. Conclusions: The results show that the GNSS-R data from “Jilin-1” Kuanfu-01B satellite can be used to measure sea surface wind speed. The data used in the paper are uncalibrated, therefore, the retrieved performances are not optimal. It is a key work to calibrate the influence of transmitted power, transmission gain, and propagation path on the DDM. [ABSTRACT FROM AUTHOR]

Gastrointestinal stromal tumors (GIST) originate from gastrointestinal mesenchymal tissues, and most of them are secondary to KIT and platelet derived growth factor receptor alpha (PDGFRA) gene mutations. This discovery has a landmark significance for the basic research, clinical diagnosis and treatment of GIST. Genetic testing is widely used in many fields, such as identifying pathological diagnosis of GIST, judging prognosis and guiding targeted drug therapy. In recent years, numerous studies have shown that liquid biopsy techniques, including circulating tumor DNA (ctDNA) detection, have shown extremely important clinical values and broad application prospects for the diagnosis and treatment of GIST. This article reviews the value of ctDNA detection in the diagnosis and treatment of GIST. [ABSTRACT FROM AUTHOR]

Objective　To investigate the role of miR-582-5p in regulating Notch1 to protect myocardium， by detecting the expression changes of miR-582-5p and Notch1 after myocardial ischemia reperfusion and HR model of HL-1 cells in mice. Methods　 The mouse myocardial ischemia-reperfusion model and HL-1 cell OGD reoxygenation model were established. The expression of miR-582-5p and Notch1 in mouse IR and cell HR was detected by qPCR，and then the targeted binding sites of miR-582-5p and Notch1 were predicted by TargetScan. Inhibitor and mimics of miR-582-5p and Notch1 were transfected into cells，and the expression of miR-582-5p and Notch1 was detected again. Finally，CCK-8 assay was used to detect the cell viability of HL-1 cells transfected with inhibitor and mimics. Results　 After HR，the expression of miR-582-5p was significantly increased （P < 0.01） and the expression of Notch1 was significantly decreased in IR mouse and HL-1 cells （P < 0.001） . After transfection of inhibitor，the expression of miR-582-5p was significantly down-regulated （P < 0.001），while Notch1 was significantly up-regulated （P = 0.017），and the viability of cardiomyocytes was significantly increased （P = 0.006）， but the result was opposite after transfection of mimics. Conclusion　 miR-582-5p can protect myocardium against myocardial ischemia and hypoxia by regulating Notch1. [ABSTRACT FROM AUTHOR]
