ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy （DR）. MethodsFourteen research centers participated in this study， which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group （120 cases） and a control group （120 cases）. The observation group was treated with Tangning Tongluo tablets， and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision， DR progression rate， retinal microhemangioma， hemorrhage area， exudation area， glycosylated hemoglobin （HbA1c） level， and TCM syndrome score were assessed before and after treatment， and the safety was observed. ResultsThe vision changed in both groups after treatment （P<0.05）， and the observation group showed higher best corrected visual acuity （BCVA） than the control group （P<0.05）. The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups， while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment， the number of microhemangiomas decreased in both the observation group （Z=-1.437， P<0.05） and the control group （Z=-2.238， P<0.05）， and it showed no significant difference between the two groups. As the treatment time prolonged， the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment， the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment， neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time， both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR， being capable of improving vision and reducing hemorrhage and exudation in the fundus.

Objective: To investigate the protective effects and underlying mechanisms of sodium pyruvate (SP) on RBC storage lesions using an oxidative damage model. Methods: Six units of leukocyte-depleted suspended RBCs (discarded for non-infectious reasons within three days post-collection) were randomly assigned to four groups: negative control (NS), positive control (PS), experimental group 1 (SP1), and experimental group 2 (SP2). Oxidative stress was induced in the PS group by the addition of hydrogen peroxide (H O ), while SP1 and SP2 received SP supplementation at different concentrations (25 mM and 50 mM, respectively) in the presence of H O . After 1 hour of incubation, RBC morphology was assessed microscopically, and biochemical indicators including glutathione (GSH), malondialdehyde (MDA), methemoglobin (MetHb), adenosine triphosphate (ATP), and Na /K -ATPase activity were measured. Results: RBCs in the PS group exhibited pronounced morphological damage, including cell shrinkage and echinocyte formation, whereas both SP-treated groups showed significantly reduced structural injury. SP treatment led to elevated GSH levels and decreased concentrations of MDA and MetHb, suggesting attenuation of oxidative stress. Additionally, SP enhanced intracellular ATP levels and Na /K -ATPase activity, thereby contributing to membrane stability. Notably, the SP2 group (50 mM) demonstrated superior protective effects compared to SP1 (25 mM). Conclusion: Sodium pyruvate effectively attenuates oxidative storage lesions in RBCs, primarily through its antioxidant properties, energy metabolism supporting ability, and celluar membrane stabilizing function. These findings suggest SP as a promising additive for enhancing the quality and safety of stored RBCs.

ObjectiveTo observe the effect of the hypertension chronic disease management platform-assisted traditional Chinese medicine （TCM） comprehensive antihypertensive regimen on blood pressure control in the real world， and evaluate patients' satisfaction with this regimen. MethodsA total of 160 patients with primary hypertension were recruited， and the patients were asked to use the hypertension chronic disease management platform for self-management and to decide whether to apply TCM comprehensive antihypertensive regimen （including Baduanjin for lowering blood pressure， acupoint massage， and Chinese medicinal tea）. One month later， the changes in patients' blood pressure and the application rate of each treatment regimen were investigated. Logistic regression analysis was used to analyze the correlation between each regimen and blood pressure changes. Sensitivity analysis was performed by excluding some patients with comorbidities that might affect the use of the regimens to verify the reliability of the research results. Interaction analysis was conducted to explore whether there was a synergistic effect between the regimens， and patient satisfaction was also surveyed. ResultsA total of 149 patients were finally included. Compared with patients who did not use TCM comprehensive antihypertensive regimen regularly， those who used it regularly had a more significant decrease in diastolic blood pressure （P＜0.05）. The results of Logistic regression analysis showed that the decrease in systolic blood pressure was associated with the use of TCM decoctions， and the decrease in diastolic blood pressure was associated with the use of TCM decoctions and regular use of TCM comprehensive antihypertensive regimen （P＜0.05）. Sensitivity analysis suggested that the above research results were stable. The results of interaction analysis showed that there was no interactive effect between antihypertensive Baduanjin and acupoint massage， antihypertensive Baduanjin and Chinese medicinal tea， or acupoint massage and Chinese medicinal tea on systolic and diastolic blood pressure （P＞0.05）. One hundred and thirty patients （130/149， 87.25%） thought the hypertension chronic disease management platform was helpful or very helpful， and 111 patients （111/149， 74.50%） thought TCM comprehensive antihypertensive regimen was helpful or very helpful. ConclusionRegular use of TCM comprehensive antihypertensive regimen helps reduce the diastolic blood pressure level in patients with primary hypertension， and patients have a high degree of satisfaction with the use of the hypertension chronic disease management platform and TCM comprehensive antihypertensive regimen.

OBJECTIVE: To evaluate the effect of manual acupuncture on endometrial blood flow parameters by three-dimensional (3D) power Doppler ultrasound in women undergoing in vitro fertilization embryo transfer (IVF-ET). METHODS: Seventy patients undergoing IVF-ET were equally randomized into traditional or sham acupuncture treatment group for totally 4 days (from the day of oocyte aspiration to the day of embryo transfer) of treatment by random envelope method at the Reproductive Medicine Center and Outpatient Department of Integrated Traditional Chinese and Western Medicine, Tongji Hospital, Tongji Medicine College, Huazhong University of Science and Technology from January 2013 to December 2015. Patients in the traditional acupuncture group accepted traditional acupuncture methods with manual acupuncture, and Zhongji (CV3), Qihai (CV 6), Sanyinjiao (SP6), Taichong (LR 3), Tianshu (ST 25), Guilai (ST 29) and Zusanli (ST 36) were chosen. Patients at the sham acupuncture group accepted shallow acupuncture methods at 4 non-meridian points at each shoulder and upper arm. Outcome measures included endometrial ultrasonic indices such as vascularization index (VI), flow index (FI) and vascularization flow index (VFI), endometrial thickness and volume, subendometrial VI (sVI), subendometrial FI (sFI), subendometrial VFI (sVFI), implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births. RESULTS: Finally, 34 patients in the traditional acupuncture group and 35 in the sham acupuncture group completed this trial. VI, FI and VFI of the traditional acupuncture group were significantly higher than those in the sham acupuncture group (P<0.05). No significant differences were found in endometrial thickness, endometrial volume, sVI, sFI, sVFI, implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births (P>0.05). CONCLUSIONS Manual acupuncture performed after oocyte aspiration and before transplantation improved the endometrial blood flow parameters VI, RI and VFI in women who underwent IVF-ET, instead of sVI, sFI and sVFI. Therefore, acupuncture might be beneficial in women undergoing IVF-ET by increasing endometrial blood flow and endometrial receptivity. (Registration No. ChiCTR2100053354).

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology， Western medicine obstetrics and gynecology， and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion， the experts concluded that chromosome， endocrine， and immune abnormalities were the key factors for the occurrence of threatened abortion， and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion， TCM has advantages in preventing miscarriages， alleviating clinical symptoms and TCM syndromes， relieving anxiety， regulating reproductive endocrine and immune abnormalities， personalized and diversified treatment， enhancing efficiency and reducing toxicity， and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

This study aims to investigate the effect of salvianolic acid B (Sal B), the active ingredient of Salvia miltiorrhiza, on H9C2 cardiomyocytes injured by oxygen and glucose deprivation/reperfusion (OGD/R) through regulating mitochondrial fission and fusion. The process of myocardial ischemia-reperfusion injury was simulated by establishing OGD/R model. The cell proliferation and cytotoxicity detection kit (cell counting kit-8, CCK-8) was used to detect cell viability; the kit method was used to detect intracellular reactive oxygen species (ROS), total glutathione (t-GSH), nitric oxide (NO) content, protein expression levels of mitochondrial fission and fusion, apoptosis-related detection by Western blot. Mitochondrial permeability transition pore (MPTP) detection kit and Hoechst 33342 fluorescence was used to observe the opening level of MPTP, and molecular docking technology was used to determine the molecular target of Sal B. The results showed that relative to control group, OGD/R injury reduced cell viability, increased the content of ROS, decreased the content of t-GSH and NO. Furthermore, OGD/R injury increased the protein expression levels of dynamin-related protein 1 (Drp1), mitofusions 2 (Mfn2), Bcl-2 associated X protein (Bax) and cysteinyl aspartate specific proteinase 3 (caspase 3), and decreased the protein expression levels of Mfn1, increased MPTP opening level. Compared with the OGD/R group, it was observed that Sal B had a protective effect at concentrations ranging from 6.25 to 100 μmol·L^-1. Sal B decreased the content of ROS, increased the content of t-GSH and NO, and Western blot showed that Sal B decreased the protein expression levels of Drp1, Mfn2, Bax and caspase 3, increased the protein expression level of Mfn1, and decreased the opening level of MPTP. In summary, Sal B may inhibit the opening of MPTP, reduce cell apoptosis and reduce OGD/R damage in H9C2 cells by regulating the balance of oxidation and anti-oxidation, mitochondrial fission and fusion, thereby providing a scientific basis for the use of Sal B in the treatment of myocardial ischemia reperfusion injury.

Objective To explore the expression of junctophilin 2(JP2)and fibroblast growth factor 23(FGF23)in a rabbit model of atrial fibrillation mediated-cardiomyopathy(AMC).Methods Rabbit models of atrial fibrillation(AF)were developed through rapid atrial stimulation and then divided into three groups:control group(pacemak-ers implanted without pacing,n=6),AF group(pacing with ejection fraction decrease＜10％,n=5),and AMC group(pacing with ejection fraction decrease≥10％,n=6).Echocardiography was performed to detect left ventric-ular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD)and left ventricular ejection fraction(LVEF).JP2 and FGF23 were detected by ELISA method.Western blot and RT-qPCR were conducted to detect protein and mRNA expression of JP2 and FGF23.Results Left atrial diameter,right atrial diameter and right ventricular diameter increased and LVEF decreased in the AMC group as compared with the control group.AMC group had lower LVEF and larger aorta and right ventricle diameter.Compared with the control group,the ex-pression of FGF23(P＜0.001)and JP2(P＜0.01)in left atrial cardiomyocytes was significantly increased in the AF group,while the expression of JP2 was decreased in the AMC group(P＜0.001).AMC group had lower expression of JP2 and FGF23 compared with AF group.Compared to the control group,plasma concentration of JP2 and FGF23 increased in the AF group and FGF23 plasma concentration increased in the AMC group.Plasma concentration of FGF23 and JP2 was lower in AMC group than that in AF group.Conclusions FGF23 expression increased and JP2 expression decreased as found in the rabbit AMC model.
