ObjectiveTo evaluate the clinical efficacy of Shenqi Yangxin decoction in the treatment of ischemic cardiomyopathy （ICM） with Qi and Yin deficiency and blood stasis syndrome and its effect on serum hydrogen sulfide （H₂S） and calcium ion （Ca²⁺）. MethodsA total of 64 ICM patients with Qi and Yin deficiency and blood stasis syndrome who met the inclusion criteria were randomly divided into a control group （n=32） and a treatment group （n=32）. All patients received conventional Western medicine treatment. The treatment group was additionally given Shenqi Yangxin decoction. The TCM syndrome score， Minnesota Living with Heart Failure Questionnaire （MLHFQ） score， left ventricular ejection fraction （LVEF）， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， 6-minute walk test （6MWT）， New York Heart Association （NYHA） cardiac function classification， and serum H₂S and Ca²⁺ levels were compared between the two groups pre- and post-treatment. ResultsTwo cases dropped out from each group during the study. Finally， 30 patients in each group were included in the analysis. There were no significant differences in age， gender， course of coronary heart disease， underlying diseases， and laboratory tests between the two groups. Compared with baseline， the TCM syndrome score， MLHFQ score， and NT-proBNP in both treatment group and control group decreased significantly （P<0.01）， LVEF， 6MWT， and H₂S increased significantly （P<0.01）， and serum Ca²⁺ increased （P<0.05）. Compared with the control group after treatment， the MLHFQ score and NT-proBNP in the treatment group decreased （P<0.05）， the TCM syndrome score decreased significantly （P<0.01）， LVEF， 6MWT， and serum Ca²⁺ increased （P<0.05）， and H₂S increased significantly （P<0.01）. The improvement degree of the NYHA cardiac function classification in the treatment group was higher than that in the control group， but there was no significant difference. ConclusionShenqi Yangxin decoction is effective in treating ICM patients with Qi and Yin deficiency and blood stasis， which could significantly improve cardiac function and quality of life， and its therapeutic effect may be related to the regulation of serum H₂S and Ca²⁺ levels.

The cooccurrence of NPM1, FLT3-ITD, and DNMT3A mutations (i.e., triple mutation) is related to dismal prognosis in patients with acute myeloid leukemia (AML) receiving chemotherapy alone. In this multicenter retrospective cohort study, we aimed to identify whether allogeneic hematopoietic stem cell transplantation (allo-HSCT) could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut AML across four transplant centers in China. Fifty-three patients with triple-mutated AML receiving allo-HSCT in complete remission were enrolled. The 1.5-year probabilities of relapse, leukemia-free survival, and overall survival after allo-HSCT were 11.9%, 80.3%, and 81.8%, respectively. Multivariate analysis revealed that more than one course of induction chemotherapy and allo-HSCT beyond CR1 were associated with poor survival. To our knowledge, this work is the largest study to explore the up-to-date undefined role of allo-HSCT in patients with triple-mutated AML. Our real-world data suggest that allo-HSCT could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut in AML.

G protein-coupled receptors (GPCRs) are the largest family of membrane proteins in eukaryotes, with nearly 800 genes coding for these proteins. They are involved in many physiological processes, such as light perception, taste and smell, neurotransmitter, metabolism, endocrine and exocrine, cell growth and migration. Importantly, GPCRs and their ligands are the targets of approximately one third of all marketed drugs. GPCRs are traditionally known for their role in transmitting signals from the extracellular environment to the cell's interior via the plasma membrane. However, emerging evidence suggests that GPCRs are also localized on mitochondria, where they play critical roles in modulating mitochondrial functions. These mitochondrial GPCRs (mGPCRs) can influence processes such as mitochondrial respiration, apoptosis, and reactive oxygen species (ROS) production. By interacting with mitochondrial signaling pathways, mGPCRs contribute to the regulation of energy metabolism and cell survival. Their presence on mitochondria adds a new layer of complexity to the understanding of cellular signaling, highlighting the organelle's role as not just an energy powerhouse but also a crucial hub for signal transduction. This expanding understanding of mGPCR function on mitochondria opens new avenues for research, particularly in the context of diseases where mitochondrial dysfunction plays a key role. Abnormalities in the phase conductance pathway of GPCRs located on mitochondria are closely associated with the development of systemic diseases such as cardiovascular disease, diabetes, obesity and Alzheimer's disease. In this review, we examined the various types of GPCRs identified on mitochondrial membranes and analyzed the complex relationships between mGPCRs and the pathogenesis of various diseases. We aim to provide a clearer understanding of the emerging significance of mGPCRs in health and disease, and to underscore their potential as therapeutic targets in the treatment of these conditions.

Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

Objective The objective of this research was to examine the cardioprotective properties of a SIRT1 agonist in mice afflicted with coronary artery disease(CAD).Methods Using the random number table method,60 male C57BL/6J mice were randomly divided into a control group,a model group,an SRT1 agonist group(Group SRT 1460,30 mg/kg),an Nrf2 inhibitor group(ML385 group,10 mg/kg),and a combined treatment group of SRT 1460+ML385,with 12 mice in each group.The control group mice were fed with normal feed,and the other groups of mice were fed with high-fat feed to create atherosclerosis mouse model.The modeling period was 12 weeks.After the successful construction of the model,ultrasonic parameters were used to detect the myocardial function of mice;two-dimensional ultrasound spot tracking technology was used to detect the strain of each layer of left ventricular myocardium.Pathological alterations in myocardial tissue were detected via HE staining,and the levels of cTnI,LDH and CK were measured using ELISA.Cardiomyocyte apoptosis was evaluated using TUNEL analysis,and levels of ROS in myocardial tissue were measured via DHE fluorescence assay.Additionally,SOD activity and MDA,GSH and Fe2+contents in myocardial tissue were determined using colorimetry.Finally,gene and protein expressions of Nrf2,GPX4,FTH1,and ACSL4 were assessed through qRT-PCR and Western blot analysis.Results A significant decrease in LVEDd and LVPWd levels was observed in the SRT 1460 group(P<0.05),whereas increases in GLSendo,GLSmid,and GCSendo levels were identified.A decrease in collagen fiber deposition was observed in the SRT 1460 group,in which the myocardium space narrowed.In comparison to the control group,the SRT 1460 group showed reductions in serum cTnI,CK,and LDH levels,cardiomyocyte apoptosis rate,ROS,MDA,and Fe2+contents,as well as ACSL4 mRNA and protein levels(P<0.05).An increase in SOD activity and GSH content as well as in Nrf2,GPX4,and FTH1 mRNA and protein levels was observed(P<0.05).By inhibiting the nuclear translocation of Nrf2,ML385 could significantly block the regulatory effect of SRT 1460(P<0.05).Conclusion It has been shown that SRT 1460 enhances GLSendo,GLSmid,and GCSmid,and improves left ventricular remodeling and systolic function in mice with CAD,in part because it regulates the Nrf2-GPX4 ferroptosis pathway.

Objective To explore the relationship between body mass index(BMI)and blood pressure(BP),blood lipids,waist-to-hip ratio(WHR),and hemoglobin(Hb)in the elderly.Methods A total of 10 978 elderly individuals aged≥65 years old in a community in Baoshan District,Shanghai from February 2023 to October 2023 were selected as the research subjects.Height,body mass,waist circumference(WC),hip circumference(HC),systolic blood pressure(SBP),diastolic blood pressure(DBP),total cholesterol(TC),high-density lipoprotein(HDL),low-density lipoprotein(LDL),Hb were measured,and BMI and WHR were calculated.According to the Chinese BMI reference standard,the elderly were divided into a lean group(BMI＜18.5 kg/m2,n= 310),a normal body mass group(18.5 kg/m2≤BMI＜24 kg/m2,n=4 692),a overweight group(24 kg/m2≤BMI＜28 kg/m2,n= 4 615),and an obese group(BMI≥28 kg/m2,n=1 361).The levels of BP,blood lipids,WHR,and Hb in the four groups were compared and correlation analysis was conducted.Results The levels of BMI,WC,HC,WHR,SBP,DBP,and Hb in elderly men were higher than those in elderly women(all P＜0.01),while the levels of TC,HDL,and LDL were lower than those in elderly women(all P＜0.01).The differences in SBP,DBP,TC,HDL,LDL,WHR,and Hb among the four groups were statistically significant(all P＜0.05),and BMI was positively correlated with SBP,DBP,TC,LDL,WHR,and Hb(r=0.109,0.064,0.041,0.042,0.108,0.089,all P＜0.01),and negatively correlated with HDL(r=﹣0.106,P＜0.01).The BMI of elderly men in the normal body mass group was higher than that of elderly women,while the BMI of elderly women in the obesity group was higher than that of elderly men(both P＜0.01).In the normal body mass group,the BMI of elderly people aged＜75 years old was higher than that of elderly people aged≥75 years old(P＜0.05).Conclusions BMI is closely related to the health of the elderly,and maintaining an ideal BMI is the foundation for health management and prevention of chronic diseases in the elderly.

Objective:To evaluate the efficacy and safety of Qingxuan Zhike granules in improving cough symptoms and shortening the course of influenza (wind-heat invading lung) in children.Methods:In this multicenter, randomized, controlled clinical trial, a total of 240 outpatient influenza patients from 7 hospitals, including the First Affiliated Hospital of Yunnan University of Traditional Chinese Medicine, from April 2023 to December 2023 were collected.The subjects were randomly divided into the control group and the experimental group via SAS software using the block randomization method.The differences between two groups were compared with t test, corrected t test and χ2 test.Subjects in the control group were given Oseltamivir phosphate granules, orally, twice a day (weight ≤15 kg, 30 mg/time; weight >15-23 kg, 45 mg/time; weight >23-40 kg, 60 mg/time; weight >40 kg, 75 mg/time; age≥13 years, 75 mg/time).In addition to Oseltamivir phosphate granules, subjects in the experimental group were also given Qingxuan Zhike granules, orally, 3 times a day (1-3 years old, 1/2 bag each time; >3-6 years old, 3/4 bag each time; >6-14 years old, 1 bag each time).After 5 days of treatment, the medication was suspended for 2 days.The effect of cough, antipyretic effect, clinical recovery rate, clinical recovery time, Canadian Acute Respiratory Illness and Flu Scale (CARIFS) score, traditional Chinese medicine (TCM) syndrome effect, complication rate, and adverse reactions were evaluated between the two groups. Results:Finally, 232 cases were included in the study, including 115 cases in the experimental group and 117 cases in the control group.Before and after treatment, there were no significant difference in CARIFS cough score between the experimental group and the control group (all P>0.05).After treatment, the change in CARIFS cough score in the experimental group [(-1.00±0.91) scores]was significantly higher than that in the control group [(-0.75±0.98) scores] ( t=-1.995, P=0.047).After treatment, the change in TCM syndrome cough score in the experimental group [(-1.69±1.51) scores] was significantly higher than that in the control group [(-0.97±1.63) scores] ( t′=-0.035, P=0.001).The time of complete regression of fever in the experimental group [(44.82±22.72) h] was shorter than that in the control group [(51.35±27.07) h], and the difference between the two groups was statistically significant ( t=-1.966, P=0.050).The fever score showed that the area under the curve between the CARIFS symptom fever score and time in the experimental group was 4.40±2.42, while that in the control group was 5.12±2.44, and the difference between the two groups was statistically significant ( t=-2.252, P=0.025).The clinical recovery rate was 93.91%(108/115) in the experimental group and 92.31%(108/117) in the control group, and there was no significant difference between the two groups ( χ2=0.233, P>0.05).The clinical recovery time in the experimental group [(2.93±1.21) d] was shorter than that in the control group [(3.29±1.15) d], and the difference between the two groups was statistically significant ( t=-2.279, P=0.024).After treatment, there was a significant difference in TCM syndrome score variation between the experimental group [(-12.00±4.13) scores] and the control group [(-10.85±4.31) scores] ( t′=-2.067, P=0.040).No complication occurred in both groups, and there was no significant difference in the incidence of adverse events between the two groups ( χ2=1.299, P>0.05). Conclusions:Qingxuan Zhike granules combined with Oseltamivir phosphate can effectively improve the cough symptoms associated with influenza in children, shorten the time and course of fever, and improve the TCM syndrome score; thus, they are safe in clinical application.

Objective To investigate the clinical application value of MRI Radiomics score(Radscore)combined with clinicopatho-logical features in predicting postoperative progression-free survival(PFS)of patients with endometrial cancer(EC).Methods A total of 127 patients with EC were selected.The radiomic features of the lesions were extracted from T2 WI,diffusion weighted imaging(DWI)and apparent diffusion coefficient(ADC)images.The features were screened by random forest model and Radscore was calcu-lated.Simultaneously,clinical and pathological characteristics of patients were collected and incorporated,and multivariate Cox regression analysis was used to screen the risk factors related to PFS.The MRI Radscore and clinicopathological features were mapped to the nomogram,and the performance of nomogram was evaluated by receiver operating characteristic(ROC)curve and calibration curve.Results Multivariate Cox regression analysis showed that progesterone receptor(PR),human epididymis protein 4(HE4)and MRI Radscore were independent risk factors for predicting PFS in patients with EC(P＜0.05).The area under the curve(AUC)of the predicted PFS at 1,3 and 5 years after surgery were 0.91,0.804 and 0.776,respectively.Calibration curves showed that nomogram had a good fit in predicting PFS in patients with EC 1,3 and 5 years after surgery.Conclusion The nomogram con-structed based on multi-sequence MRI Radscore and clinicopathological features has favorable accuracy and stability in predicting postoperative PFS in individuals diagnosed with EC.

Objective To investigate the clinical effect of digital subtraction angiography(DSA)-guided foam sclerotherapy on lower limb varicose veins.Methods The relevant data of patients with lower limb varicose veins treated by DSA-guided foam sclerotherapy were analyzed retrospectively.At the same time,the safety and efficacy were compared before and after operation according to clinical etiology anatomy pathophysiology(CEAP)and clinical symptoms.Results Among the 278 affected limbs treated,2(0.72％)had neurological complications during treatment,8(2.88％)had chest tightness or cough during treatment,7(2.52％)had thrombophlebitis after treatment,and 28(10.07％)had hyperpigmentation after treatment.No serious complications such as skin necrosis,deep vein thrombosis(DVT)or pulmonary embolism(PE)occurred.There were 48 cases of grade C1 and 201 cases of grade C2 before treat-ment,while 244 cases of grade C0 and 26 cases of grade C1 after treatment,and the differences were statistically significant(P＜0.05).Conclusion DSA-guided foam sclerotherapy on lower limb varicose veins is a safe and effective minimally invasive treatment with high technical success rate.
