ObjectiveTo evaluate the impact of yang-reinforcing and blood-activating therapy on the long-term prognosis for patients with dilated cardiomyopathy (DCM) of yang deficiency and blood stasis syndrome. MethodsA retrospective cohort study was conducted involving 371 DCM patients with yang deficiency and blood stasis syndrome. The yang-reinforcing and blood-activating therapy was defined as the exposure factor. Patients were categorized into exposure group (186 cases) and non-exposure group (185 cases) according to whether they received yang-reinforcing and blood-activating therapy combined with conventional western medicine for 6 months or longer. The follow-up period was set at 48 months, and the Kaplan-Meier survival analysis was used to assess the cumulative incidence of major adverse cardiovascular events (MACE) in both groups. Cox regression analysis was used to explore the impact of yang-reinforcing and blood-activating therapy on the risk of MACE, and subgroup analysis was performed. Changes in traditional Chinese medicine (TCM) syndrome score, left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), left ventricular end-diastolic diameter (LVEDD), and Minnesota Living with Heart Failure Questionnaire (MLHFQ) score were compared between groups at the time of first combined use of yang-reinforcing and blood-activating therapy (before treatment) and 1 year after receiving the therapy (after treatment). ResultsMACE occurred in 31 cases (16.67%) in the exposure group and 47 cases (25.41%) in the non-exposure group. The cumulative incidence of MACE in the exposure group was significantly lower than that in the non-exposure group [HR=0.559, 95%CI(0.361,0.895), P=0.014]. Cox regression analysis showed that yang-reinforcing and blood-activating therapy was an independent factor for reducing the risk of MACE in DCM patients [HR=0.623, 95%CI(0.396,0.980), P=0.041], and consistent results were observed in different subgroups. Compared with pre-treatment, the exposure group showed decreased TCM syndrome score and MLHFQ score, reduced LVEDD, and increased LVEF and LVFS after treatment (P<0.05); in the non-exposure group, TCM syndrome score decreased, LVEF and LVFS increased, and LVEDD reduced after treatment (P<0.05). After treatment, the exposure group had higher LVEF and LVFS, smaller LVEDD, and lower TCM syndrome score and MLHFQ score compared with the non-exposure group (P<0.05). ConclusionCombining yang-reinforcing and blood-activating therapy with conventional western medicine can reduce the risk of MACE in DCM patients with yang deficiency and blood stasis syndrome, meanwhile improving their clinical symptoms, cardiac function, and quality of life.

ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

ObjectiveTo observe the effect of Zishen Tiaogan prescription on the oxidative stress injury in the rat model of diminished ovarian reserve (DOR) and explore the role of the Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway. MethodsForty-eight female SD rats were randomly assigned into a normal group (n=12) and a modeling group (n=36). The rats in the modeling group received subcutaneous injection of galactose (350 mg·kg-1) combined with immobilization stress daily. After 28 days of modeling, 6 rats in the normal group and 6 rats in the modeling group were sacrificed to examine the modeling results. The successfully modeled rats were assigned into model, estradiol valerate (0.09 mg·kg-1), and low-, medium-, and high-dose (6.39, 12.78, 25.56 g·kg-1, respectively) Zishen Tiaogan prescription groups. The intervention lasted for 4 weeks with 6 animals per group. Hematoxylin-eosin staining was used to observe the estrous cycle and the pathological changes in the ovarian tissue. The ovarian index was calculated. Enzyme-linked immunosorbent assay was employed to measure the serum levels of sex hormones and oxidative stress-related indexes. Western blot and real-time PCR were employed to determine the protein and mRNA levels, respectively, of Nrf2, Keap1 and HO-1 in the ovarian tissue. The positive expression of superoxide dismutase 2 (SOD2) in the ovarian tissue was detected by immunohistochemistry (IHC). ResultsCompared with the normal group, the model group showed reduced follicles in the ovary, loose arrangement of the follicle granule layer, declined levels of anti-Mullerian hormone (AMH) and estradiol (E2) in the serum, elevated levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) (P<0.01), lowered levels of superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH) (P<0.01), and increased accumulation of malondialdehyde (MDA) (P<0.01). In addition, the modeling led to up-regulated protein and mRNA levels of Keap1 (P<0.01), the expression of Nrf2 and HO-1 protein was significantly decreased (P<0.01), the mRNA expression of Nrf2 was significantly decreased (P<0.05), the mRNA expression of HO-1 was significantly decreased (P<0.01), in the ovarian tissue. Compared with model group, the estradiol valerate and low-, medium-, and high-dose Zishen Tiaogan prescription groups showed increases in the ovarian index (P<0.01) and serum E2 and AMH levels (P<0.01), declined levels of FSH and LH (P<0.01), increased follicles in the ovary, elevated levels of SOD, CAT, and GSH, and reduced accumulation of MDA (P<0.05, P<0.01). Furthermore, these groups showcased down-regulated protein and mRNA levels of Keap1 (P<0.01), the expression of Nrf2 protein was significantly increased (P<0.01), the expression level of HO-1 protein was increased (P<0.05,P<0.01), and increased positive expression of SOD2 (P<0.01). ConclusionZishen Tiaogan prescription can regulate the serum levels of hormones, down-regulate the expression of Keap1, up-regulate the expression of Nrf2, HO-1, and SOD2, enhance the antioxidant capacity, and reduce the peroxidation damage in the ovarian tissue to improve the ovarian reserve function in the rat model of DOR. High-dose Zishen Tiaogan prescription demonstrated the best effect and the mechanism is associated with the regulation of the Keap1/Nrf2/HO-1 pathway.

[Objective] To explore the feasibility of using whole blood as a source of NK cells for allogeneic CAR NK cell therapy and activated NK cell reinfusion therapy, and initially construct a technical system for the separation and purification of NK cells from whole blood. [Methods] All peripheral blood mononuclear cells (PBMCs) were enriched from 400 mL of whole blood by manual separation and machine separation, respectively. The erythrocyte loss rate, PBMCs number, NK cell purity of the two methods were compared. NK cells were sorted from PBMCs by three separation and enrichment methods as immunomagnetic bead negative selection method, platelet lysate culture expansion and PERCOLL density gradient separation method, and the purity and yield of NK cells, the activity of NK cells and the tumor-killing ability of the three separation and enrichment methods were compared. [Results] The proportion of NK cells in the lymphocyte population was higher in the manual separation method than in the machine separation method[(13.16±5.16)% vs (8.56±3.92)%, P<0.05]; the number PBMCs was lower in the manual separation method than in the machine separation method[(4.09±1.80)×108vs (6.49±2.16)×108, P<0.05], and there was no difference in the red blood cell loss between the two methods (P>0.05). The purity of NK cells isolated and enriched from PBMCs by manual separation method using immunomagnetic was (96.77±2.31)%; the yield was (56.27±10.47)%; the inhibition of tumor proliferation was (38.67±14.05)%; and the tumor killing rate was (19.90±8.05)%. The purity of NK cells isolated and enriched from PBMCs by manual separation method using platelet lysis culture expansion method was the highest at day 7, which was (54.84±15.80)%; the cell expansion multiple could reach 16.92±6.28 at day 7; the in vitro tumor killing rate of NK cells was (15.83±5.5)%; the tumor inhibition rate was (44.33±13.5)%; and there was no difference in the toxicity and activity of NK cells between the two methods (P>0.05). The purity of NK cells isolated and enriched by PERCOLL density gradient separation method was (15.83±5.82)%, and the yield was (14±6.25)%, which was significantly lower than the other two methods. [Conclusion] PBMCs isolated from whole blood by manual separation and NK cells enriched by negative selection with immunomagnetic beads have the potential to provide NK cell materials for CAR-NK cell therapy, and NK cells enriched by platelet lysate-conditioned medium have the potential to provide NK cells for large-scale NK cell activation reinfusion therapy.

ObjectiveTo explore the possible mechanism of Qishao Tongbi Capsule (芪芍通痹胶囊, QTC) in the treatment of intervertebral disc degeneration (IDD). MethodsSeventy-five rats were randomly divided into control group, model group, low-dose QTC group, high-dose QTC group, high-dose QTC +agonist group, with 15 rats in each group. Except for the control group, all other groups were subjected to a fibrous ring puncture to prepare an IDD model. After modeling, rats in low-dose QTC group and high-dose QTC group were given QTC at doses of 0.2 and 0.8 g/(kg·d) by gavage, respectively. Rats in high-dose QTC+ agonist group was given QTC at 0.8 g/(kg·d) and SKL2001 solution at 10 mg/(kg·d) by gavage. The control group and model group were given 10 ml/(kg·d) distilled water by gavage. All treatments were given once a day for 4 consecutive weeks. After treatment, X-ray and magnetic resonance imaging (MRI) were used to detect IDD degree. Hematoxylin-eosin (HE) staining and Safranin O-Fast Green staining were used to observe the morphological changes of the intervertebral disc tissue. Immunohistochemical staining was performed to examine the levels of proteoglycan, type Ⅱ collagen (COL Ⅱ), and matrix metalloproteinase-3 (MMP-3) in the intervertebral disc tissue. Western blotting was used to detect the extracellular matrix (ECM)-related proteins (proteoglycan, COL Ⅱ, MMP-3, MMP-9, MMP-13), aging-related proteins (P53, P21, P16), apoptosis related proteins, including B-cell lymphoma/leukemia 2 (BCL-2), BCL-2 related X protein (BAX), Cleaved Caspase-3, and Wnt/β-catenin pathway related proteins such as Wnt3a, glycogen synthase kinase-3β (GSK-3β) and β-catenin in the intervertebral disc nucleus pulposus (NP) tissue. Reverse Transcription Quantitative Polymerase Chain Reaction (RT-qPCR) was used to assess the mRNA expression of Wnt3a, GSK-3β, and β-catenin in intervertebral disc tissue. ResultsCompared with the model group, rats in the low-dose QTC group and high-dose QTC group exhibited improved DHI, decreased Pfirmann grading, and alleviated IDD. The structural integrity of the NP and annulus fibrosus increased, and the number of the NP increased. The levels of proteoglycan, COL Ⅱ, BCL-2 and GSK-3β increased, while the levels of MMP-3, MMP-9, MMP-13, P53, P21, P16, BAX, Cleaved Caspase-3, Wnt3a and β-catenin protein decreased. The mRNA expression of Wnt3a and β-catenin mRNA decreased, while GSK-3β mRNA expression increased (P<0.05). Compared with the low-dose QTC group, the high-dose QTC group showed further improvements in DHI, decrease in Pfirrmann grading (P<0.05), and greater alleviation of IDD. The structural integrity of NP and annulus fibrosus was further enhanced, and the number of NP cells further increased. The levels of proteoglycan, COL Ⅱ, BCL-2 and GSK-3β were higher, while the levels of MMP-3, MMP-9, MMP-13, P53, P21, P16, BAX, Cleaved Caspase-3, Wnt3a and β-catenin were lower. The mRNA expression of Wnt3a and β-catenin decreased, while GSK-3β mRNA expression increased (P<0.05). Compared with the high-dose QTC group, the high-dose QTC +agonist group showed a decrease of DHI, an increase of Pfirmann grading (P<0.05), significant aggravation of IDD, reduction in structural integrity of the NP and annulus fibrosus, a decrease of NP cell count, lower levels of proteoglycan, COL Ⅱ, BCL-2 and GSK-3β, and higher levels of MMP-3, MMP-9, MMP-13, P53, P21, P16, BAX and Cleaved Caspase-3. Additionally, GSK-3β mRNA expression decreased (P<0.05). ConclusionQTC can inhibit NP cell aging, apoptosis, and ECM degradation in IDD rats, and its therapeutic effect may be mediated through the inhibition of the Wnt/β-catenin pathway.
