Objectives: To investigated the safety and efficacy of treating patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) and elevated levels of N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) with levosimendan within 24 hours of first medical contact (FMC). Methods: This multicenter, open-label, block-randomized controlled trial (NCT03189901) investigated the safety and efficacy of levosimendan as an early management strategy of acute heart failure (EMS-AHF) for patients with NSTEMI and high NT-proBNP levels. This study included 255 patients with NSTEMI and elevated NT-proBNP levels, including 142 males and 113 females with a median age of 65 (58-70) years, and were admitted in the emergency or outpatient departments at 14 medical centers in China between October 2017 and October 2021. The patients were randomly divided into a levosimendan group (n=129) and a control group (n=126). The primary outcome measure was NT-proBNP levels on day 3 of treatment and changes in the NT-proBNP levels from baseline on day 5 after randomization. The secondary outcome measures included the proportion of patients with more than 30% reduction in NT-proBNP levels from baseline, major adverse cardiovascular events (MACE) during hospitalization and at 6 months after hospitalization, safety during the treatment, and health economics indices. The measurement data parameters between groups were compared using the t-test or the non-parametric test. The count data parameters were compared between groups using the χ² test. Results: On day 3, the NT-proBNP levels in the levosimendan group were lower than the control group but were statistically insignificant [866 (455, 1 960) vs. 1 118 (459, 2 417) ng/L, Z=-1.25,P=0.21]. However, on day 5, changes in the NT-proBNP levels from baseline in the levosimendan group were significantly higher than the control group [67.6% (33.8%,82.5%)vs.54.8% (7.3%,77.9%), Z=-2.14, P=0.03]. There were no significant differences in the proportion of patients with more than 30% reduction in the NT-proBNP levels on day 5 between the levosimendan and the control groups [77.5% (100/129) vs. 69.0% (87/126), χ²=2.34, P=0.13]. Furthermore, incidences of MACE did not show any significant differences between the two groups during hospitalization [4.7% (6/129) vs. 7.1% (9/126), χ²=0.72, P=0.40] and at 6 months [14.7% (19/129) vs. 12.7% (16/126), χ²=0.22, P=0.64]. Four cardiac deaths were reported in the control group during hospitalization [0 (0/129) vs. 3.2% (4/126), P=0.06]. However, 6-month survival rates were comparable between the two groups (log-rank test, P=0.18). Moreover, adverse events or serious adverse events such as shock, ventricular fibrillation, and ventricular tachycardia were not reported in both the groups during levosimendan treatment (days 0-1). The total cost of hospitalization [34 591.00(15 527.46,59 324.80) vs. 37 144.65(16 066.90,63 919.00)yuan, Z=-0.26, P=0.80] and the total length of hospitalization [9 (8, 12) vs. 10 (7, 13) days, Z=0.72, P=0.72] were lower for patients in the levosimendan group compared to those in the control group, but did not show statistically significant differences. Conclusions: Early administration of levosimendan reduced NT-proBNP levels in NSTEMI patients with elevated NT-proBNP and did not increase the total cost and length of hospitalization, but did not significantly improve MACE during hospitalization or at 6 months.

This study aims to elucidate the underlying mechanism of Erxian Decoction(EXD) against neurogenesis impairment in late-onset depression(LOD) rats based on cerebrospinal fluid(CSF) proteomics. A total of 66 20-21-month-old male Wistar rats were randomized into naturally aged(AGED) group, LOD group, and EXD group. All rats received chronic unpredictable mild stress(CUMS) for 6 weeks for LOD modeling except for the AGED group. During the modeling, EXD group was given EXD(ig, twice a day at 4 g·kg~(-1)) and other groups received equivalent amount of normal saline(ig). After modeling, a series of behavioral tests, such as sucrose preference test(SPT), open-field test(OFT), forced swimming test(FST), and Morris water maze test(MWMT) were performed. Immunofluorescence method was used to detect the number of Ki-67/Nesti-positive cells and BrdU/DCX-positive cells in the hippocampal DG area of each group. High-concentration corticosterone(CORT) was combined with D-galactose(D-gal) to simulate the changes of LOD-related stress and aging and the proliferation and differentiation of primary neural stem cells of hippocampus in each group were observed. Data independent acquisition(DIA)-mass spectrometry(MS) was used to analyze the differential proteins in CSF among groups and bioinformatics analysis was performed to explore the biological functions of the proteins. Behavioral tests showed that sucrose consumption in SPT, total traveling distance in OFT, and times of crossing the platform in MWMT were all reduced(P<0.01) and the immobility time in FST was prolonged(P<0.01) in the LOD group compared with those in the AGED group, suggesting that LOD rats had developed depression symptoms such as anhedonia, decreased locomotor activity ability, and cognitive dysfunction. Behavioral abnormalities were alleviated(P<0.01, P<0.05) in the EXD group as compared with those in the LOD group. Immunofluorescence results demonstrated that Ki-67/Nesti-positive cells and BrdU/DCX-positive cells in the hippocampal DG area were fewer(P<0.05) in LOD group than in the AGED group, and the positive cells in the EXD group were more(P<0.05) than those in the LOD group. In vitro experiment showed that the proliferation and differentiation of primary hippocampal neural stem cells under the CORT+D-gal treatment were reduced(P<0.01). The proliferation rate of neural stem cells decreased(P<0.05) in CORT+D-gal+LOD-CSF group but increased(P<0.01) in CORT+D-gal+EXD-CSF group compared with that in the CORT+D-gal group. A total of 2 620 proteins were identified from rat CSF, with 135 differential proteins between the LOD group and AGED group and 176 between EXD group and LOD group. GDF11, NrCAM, NTRK2, and GhR were related to neurogenesis and 39 differential proteins were regulated by both LOD and EXD. EXD demonstrated obvious anti-LOD effect, as it improved the locomotor activity ability and cognitive function of LOD rats and protected the proliferation and differentiation of hippocampal neural stem cells. EXD exerts anti-LOD effect by regulating the proteins related to neurogenesis in CSF, such as GDF11, NrCAM, NTRK2, and GhR and maintaining hippocampal neurogenesis.

OBJECTIVETo determine the effectiveness and safety of Xinfeng Capsules (XFC) for the treatment of rheumatoid arthritis (RA) patients with decreased pulmonary function.

METHODSThis was a randomized controlled clinical trial of 80 RA patients. Participants were assigned to the trial group (40 cases) and the control group (40 cases) by block randomization. The trial group was treated with XFC, three pills each time three times daily for 2 months. The control group was treated with tripterygium glycoside (TPT), two pills each time three times daily for 2 months. Both groups were followed up after 2 months. The clinical effects, changes in joint and pulmonary function, and quality of life before and after treatment were observed; safety indices were also evaluated.

RESULTSPain, swelling, tenderness, and duration of morning stiffness of joints were obviously decreased after treatment in both the trial and the control groups compared with baseline (P<0.01). Compared with before treatment, hand grip strength increased significantly after treatment in the trial group (P=0.0000); pulmonary function parameters such as forced expiratory volume in the first second of expiration/forced vital capacity (FEV1/FVC), 50% of the expiratory flow of forced vital capacity (FEF50), carbon monoxide diffusing capacity (DLco) were increased (P<0.01 or P<0.05); measures of quality of life such as role-physical, body pain, vitality and mental health were also improved after treatment in the trial group (all P<0.05). Joint swelling in the trial group decreased compared with the control group (P=0.0043), while hand grip strength was increased after treatment (P=0.0000). The increase in FEF50, DLco, and the dimensions of quality of life such as vitality and mental health were all significantly greater in the trial group than the control group (P<0.05 or P<0.01).

CONCLUSIONSXFC not only relieved joint pain in RA patients, but also significantly improved the ventilation and diffusion function of the lungs. Therefore, XFC could improve the whole body function and enhance the quality of life of RA patients.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP &ge; 140 mmHg and/or diastolic BP &ge; 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

This study was purpose to investigate the B7-H3 expression in multiple myeloma cell lines and CD138 cells of patients with multiple myeloma, and explore its clinical significance. Three myeloma cell lines (RPMI8226, U266 and H929) were used. Forty-five patients with multiple myeloma were enrolled in the study. The expression of B7-H3 was detected by flow cytometry and RT-PCR. The relationship between B7-H3 and clinical prognostic factor was analyzed. The results showed that (1)In myeloma cell lines, high expression of B7-H3 was seen in RPMI8226 (92.30 ± 1.1)% and U266 (79.03 ± 1.2)% but not in H929 cell line (4.26 ± 0.2)%. (2) Exogenous IL-6 had no effect on upregulation of B7-H3 in myeloma cell lines. (3) In multiple myeloma patients, the proportions of B7-H3 positive cells in newly diagnosed, remission and relapsed patients were (48.58 ± 33.593)%, (22.16 ± 18.853)%, and (57.65 ± 28.296)%, respectively. The difference between the newly diagnosed and remission patients, and remission and relapsed patients was significant (P = 0.023, P = 0.004). (4)High B7-H3 expression was correlated with high numbers of bone destruction and high levels of serum calcium (P = 0.027, P = 0.046, respectively). It is concluded that the relation of B7-H3 molecule expression with prognosis of multiple myeloma may be negative, but with degree of bone destruction is positive, thus the high expression of B7-H3 may correlated with disease progression and bone destruction of patients with multiple myeloma.

OBJECTIVETo investigate the change of CD4⁺CD25(high)CD127(low) regulatory T cells (Tregs) percentage in patients with primary immune thrombocytopenia (ITP) treated by different methods.

METHODSOne hundred and thirty-eight newly diagnosed adult ITP patients (57 male, median age 40 years, range 18-70 years) were enrolled in this study, who were randomly separated into three regiment groups, namely prednisolone (PSL, 1.5 mg/kg for 2-4 weeks and subsequently stepwise reduction) group enrolled 49 patients, dexamethasone [(one course of high-dose dexamethasone (HDD) 40 mg/day, d1-4] 45 patients, and rituximab plus HDD (rituximab 100 mg on days 7, 14, 21, 28 and HDD) group 44 patients. Peripheral blood was taken in ITP patients of each group before treatment, 14 d and 28 d after treatment. The percentages of CD4⁺CD25(high)CD127(low) Tregs in 30 healthy controls and 138 patients were analyzed by flow cytometry.

RESULTSOverall response (OR) rates of PSL, HDD and R+HDD groups at day 28 were 69.4%, 66.7% and 79.5% respectively with no difference. After the following 12 months, sustained response (SR) was more pronounced in R+HDD group compared to the other two groups (R+HDD vs PSL: 66.7% vs 37.8%, P<0.05; R+HDD vs HDD: 66.7% vs 22.7%, P<0.05). The percentage of CD4⁺CD25(high)CD127(low) Tregs in peripheral blood of ITP patients [(1.67±0.70)%] was significantly lower than in healthy control group; After treatment, the percentages of Tregs in peripheral blood of patients both at day 14 and 28 in R+HDD group remarkably decreased compared with before treatment [(4.28±1.09)% vs (1.68±0.68)%, P<0.05; (4.44±0.63)% vs (1.68±0.68)%]. The percentages of Tregs at day 14 in both other two groups decreased notably compared with before treatment. But the Tregs levels measured at day 28 in PSL and HDD groups were similar with before treatment.

CONCLUSIONThe percentage of CD4⁺CD25(high)CD127(low) Tregs in peripheral blood of ITP patients was lower than healthy individual. The higher SR of patients treated by R+HDD was related to its ability to up-regulate the percentage of CD4⁺CD25(high)CD127(low) Tregs.

OBJECTIVETo compare the efficacy and safety of low-dose rituximab combined with different dosage of glucocorticoids for immune thrombocytopenia (ITP).

METHODSSeventy-four patients (35 male, median age 34 years, range 18-70 years) including 60 newly-diagnosed, 6 persistent, 5 chronic and 3 refractory patients were enrolled in this study, and separated into control (36 cases) and experimental (38 cases) groups according to the dosage of glucocorticoids. Patients in both groups received dexamethasone 40 mg/day on days 1-4, followed by rituximab 100 mg on days 7, 14, 21, 28. The patients in experimental group also received decrements of prednisone 60, 30, 20, 10 mg/day on days 5-7, 8-14, 15-21, 22-28. The initial, long-term efficacy and safety were evaluated.

RESULTSPlatelet counts of all patients at day 4 remarkably increased, with the median platelet count from 11(1-26) × 10⁹/L to 84(23-132) × 10⁹/L in control group, and 10(2-20) × 10⁹/L to 80(22-115) × 10⁹/L in experimental group; the platelet counts of patients at day 14 in experimental group [163(19-262) × 10⁹/L] was higher than that of control group [98(18-238) × 10⁹/L] (P<0.05). The overall response (OR) rates at day 28 in experimental group (84.21%) was significantly higher than that of control group (66.67%, P = 0.03). There was no significant difference of sustained response (SR) rates in two groups (63.89%vs 65.79%, 58.33%vs 60.53%, P > 0.05) at six and twelve months follow-up points. Both groups showed similar incidence of adverse events, and no patients discontinued the treatment due to side effects.

CONCLUSIONLow-dose rituximab and glucocorticoids was an effective method for ITP patients, and maintenance treatment with decrements of prednisone contributed to improving earlier CR rate.
