OBJECTIVE To investigate the clinical efficacy and safety of Zhengxintai granules as in the treatment of microvascular angina (MVA) following percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI) and qi deficiency and blood stasis syndrome. METHODS Patients with STEMI and qi deficiency and blood stasis syndrome who underwent PCI and developed MVA and were admitted to the Jinan Fourth People’s Hospital (Jinan Cardiovascular Hospital) from March 2022 to March 2025 were selected, they were randomly divided into the control group and the observation group according to a random number table, with 76 cases in each group. Patients in the control group received conventional Western medicine treatment combined with a placebo, while patients in the observation group received Zhengxintai granules (5 mg per dose, three times daily, for 8 weeks) in addition to conventional Western medicine treatment. The clinical efficacy [including the total effective rate of traditional Chinese medicine (TCM) syndrome improvement and the total effective rates of Western clinical efficacy] was compared between the two groups. The following indicators were detected before and after treatment: TCM syndrome scores, angina pectoris episodes [daily attack frequency, duration per attack, Visual Analogue Scale (VAS) score], cardiac function indicators [lactate dehydrogenase (LDH), N-terminal pro-B-type natriuretic peptide (NT-proBNP), left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic dimension (LVESD), left ventricular ejection fraction (LVEF), cardiac output (CO), fractional shortening (FS)], coagulation function indicators [thrombin time (TT), prothrombin time (PT), fibrinogen (FIB)], fibrinolytic marker (D-dimer), vascular endothelial function indicators [vascular endothelial growth factor (VEGF), nitric oxide (NO), endothelin-1 (ET-1)] and myocardial microcirculation hemodynamic indicators [end-diastolic velocity (EDV), peak systolic velocity (PSV), resistance index (RI), pulsatility index (PI)]. The quality of life [Seattle Angina Questionnaire (SAQ) score] and the incidence of adverse reactions were also compared between the two groups. RESULTS There was no patient dropout during the entire course of the study. The total effective rates of improvement in TCM syndromes and the total effective rates of Western clinical efficacy in the observation group were significantly higher than those in the control group (93.42% vs. 82.89%, 94.74% vs. 84.21%, P<0.05). Before the treatment, the comparison of each examination indicator between the two groups showed no statistically significant differences (P>0.05). Compared with before treatment, the TCM syndrome scores, the number of daily angina pectoris attacks and the duration of each attack, the VAS scores, LDH, NT-proBNP, FIB, D-dimer, ET-1 levels, LVEDD, LVESD, RI and PI after treatment in both groups were significantly reduced, shortened or decreased (P<0.05); VEGF and NO levels, LVEF, CO, FS, TT, PT, EDV, PSV, and the standard scores of five dimensions including angina pectoris stability, as well as the total scores of SAQ, all significantly increased or prolonged (P<0.05). Furthermore, the improvements in the aforementioned indicators (except for LVEF) in the observation group were significantly greater than those in the control group (P<0.05). There was no statistically significant difference in the total incidence of adverse reactions between the two groups (P>0.05). CONCLUSIONS Zhengxintai granules, when used as an adjunct to conventional Western medicine, can significantly alleviate the related symptoms of MVA in STEMI patients with qi deficiency and blood stasis syndrome after PCI, repair damaged cardiac function, restore the balance of the coagulation-fibrinolysis system, improve vascular endothelial function and myocardial microcirculation perfusion, and significantly enhance the quality of life of patients

Objective:
To explore the muscle mass index (MMI) among adolescents in Xinjiangs agricultural and pastoral areas and its association with cardiovascular risk factors, providing references and basis for the prevention and intervention of cardiovascular diseases among adolescents in these regions.
Methods:
From March to July 2023, a total of 1 842 students aged 13-18 years from four middle schools in Yili agricultural and pastoral areas of Xinjiang were selected using cluster random sampling. Measurements of muscle mass, physical indicators, questionnaires, and blood samples were conducted and analyzed. Statistical analyses were performed using oneway analysis of variance, Kruskal-Wallis H test, Mann-Whitney U test, and Logistic regression analysis.
Results:
There were significant differences in weight,body mass index (BMI),waist circumference,muscle mass,systolic blood pressure,diastolic blood pressure,total cholesterol,highdensity lipoprotein cholesterol and fasting blood glucose among adolescents with severe, insufficient, good, and sufficient MMI in Xinjiangs agricultural and pastoral areas(F=326.78,634.76,261.67,134.56,80.14,16.78,5.84,21.67,3.42,P<0.01). Logistic regression analysis showed that, after adjusting age and BMI, the risk of cardiovascular risk factors aggregation in adolescents with good (OR=0.55-0.62) and adequate (OR=0.52-0.57) MMI were lower than that in adolescents with insufficient MMI (P<0.05). After gender stratification, the risk of cardiovascular risk factors aggregation in adolescents with good MMI for boys (OR=0.48-0.62) and with good MMI for girls (OR=0.61) were also lower than that in adolescents with insufficient MMI (P<0.05).
Conclusions
MMI in adolescents from agricultural and pastoral areas of Xinjiang are positively correlated with cardiovascular health. Future efforts should focus on muscle strength training for adolescents in these areas, as improving MMI can play a positive role in promoting cardiovascular health in adolescents.

ObjectiveTo explore the feasibility, evaluation methods and metabolic differences of high-fat diet(HFD) combined with myocardial ischemia-reperfusion injury(MIRI) to establish a rat model of myocardial ischemia-reperfusion with phlegm and blood stasis blocking collaterals syndrome(PBSBCS). MethodsThirty-two SD rats were randomly divided into the sham operation, HFD, MIRI, and MIRI+HFD groups. Rats in the sham operation and MIRI groups were fed a standard diet(regular chow), while the HFD and MIRI+HFD groups received a HFD for 10 weeks. Rats in the MIRI and MIRI+HFD groups underwent myocardial ischemia-reperfusion surgery, while the sham operation group underwent only thread placement without ligation. Cardiac function was assessed via small-animal echocardiography, including left ventricular ejection fraction(EF), left ventricular fractional shortening(FS), cardiac output(CO), and stroke volume(SV). Serum levels of creatine kinase(CK), CK-MB, triglyceride(TG), total cholesterol(TC), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), lactate dehydrogenase(LDH), endothelin-1(ET-1), endothelial nitric oxide synthase(eNOS), tumor necrosis factor-α(TNF-α), interleukin-18(IL-18), oxidized LDL(ox-LDL), and cardiac troponin T(cTnT) were measured by biochemical assays and enzyme-linked immunosorbent assay(ELISA). Myocardial histopathology was evaluated via hematoxylin-eosin(HE) staining, while myocardial infarction and no-reflow area were assessed using 2,3,5-triphenyltetrazolium chloride(TTC), Evans blue, and thioflavin staining. Changes in syndrome characteristics[body weight, tongue surface red-green-blue [RGB] values, and pulse amplitude] of PBSBCS were recorded. Serum differential metabolites were analyzed by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS). ResultsCompared with the sham operation group, the HFD and MIRI+HFD groups showed significant increases in body weight(P<0.01), RGB values and pulse amplitude decreased in the HFD, MIRI and MIRI+HFD groups, TC, TG, LDL-C and ox-LDL levels increased in the HFD and MIRI+HFD groups, while HDL-C decreased. Blood perfusion peak time and myocardial no-reflow area increased, serum eNOS level decreased, and CK-MB, LDH, and cTnT activities increased in the HFD, MIRI and MIRI+HFD groups(P<0.05, P<0.01). Whole blood viscosity was increased in the HFD group at medium shear rate, and in the MIRI and MIRI+HFD groups at low, medium and high shear rates(P<0.05, P<0.01). Platelet aggregation rate increased in the MIRI and MIRI+HFD groups, accompanied by elevated ET-1, TNF-α, and IL-18 levels, reduced cardiac function indices, expanded myocardial no-reflow and infarction areas, and increased serum CK, CK-MB, LDH, and cTnT activities(P<0.05, P<0.01). Compared with the MIRI group, the HFD and MIRI+HFD groups showed significant increase in body weight, TC, TG, LDL-C and ox-LDL levels, and significant decrease in HDL-C content(P<0.01). The MIRI+HFD group showed decrease in RGB values and pulse amplitude, and an increase in whole blood viscosity, platelet aggregation, blood perfusion peak time, myocardial no-reflow and infarction areas, elevated ET-1, TNF-α and IL-18 levels, decreased eNOS content, EF and SV, increased serum CK, CK-MB and cTnT activities, and worsened myocardial pathology(P<0.05). Compared with the HFD group, the MIRI+HFD group showed similar aggravated trends(P<0.05, P<0.01). Metabolomics results showed that 34 potential biomarkers involving 13 common metabolic pathways were identified in the MIRI+HFD group compared with the sham operation group. ConclusionThe MIRI group resembles blood stasis syndrome in hemodynamics and myocardial injury, and the HFD group mirrors phlegm-turbidity syndrome in lipid profiles and tongue characteristics. While the MIRI+HFD group aligns with PBSBCS in comprehensive indices, effectively simulating clinical features of coronary heart disease(CHD), which can be used for the evaluation of the pathological mechanism and pharmacodynamics of CHD with PBSBCS.

ObjectiveTo investigate the preparation method of a mouse model of cerebral infarction with Qi and Yin deficiency syndrome induced by streptozotocin(STZ) combined with the photochemical method, and to evaluate the biological basis of the established model. MethodsForty C57B6/J mice were randomly divided into the normal and model groups, with 20 mice in each group. The normal group received no treatment, while the model group was injected intraperitoneally with 55 mg·kg-1 of STZ once a day for 5 days. Fourteen days post-STZ induction, 10 mice from the normal group were randomly taken into the photochemical group, while 10 mice from the model group were randomly taken into the STZ+photochemical group. Rose Bengal solution injection combined with 520 nm laser irradiation was used to cause thrombosis and induce cerebral infarction in mice. Syndrome indexes for Qi and Yin deficiency were assessed by general state observation, body weight, grip strength, rectal temperature, behavioral experiments, energy metabolism, tongue color[red(R), green(G), blue(B)] values, adenosine triphosphate(ATP) content, corticotropin-releasing factor(CRF) and triiodothyronine(T3) levels. The pathological changes of cerebral infarction in mice were evaluated by detecting serum superoxide dismutase(SOD), interleukin-1β(IL-1β), IL-6, and tumor necrosis factor-α(TNF-α) levels in combination with Bederson score. Finally, the endogenous metabolites in mice were detected by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS), and multivariate statistical analysis was performed by partial least squares-discriminant analysis(PLS-DA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). The data filtering criteria were set as variable importance in the projection(VIP) value> 1, fold change(FC)<0.8 or FC>1.2, P<0.05, to obtain differential metabolites. Then MetaboAnalyst 3.0 was utilized for pathway enrichment analysis of the differential metabolites, aiming to explore the metabolic profile changes and biological basis of mice with Qi and Yin deficiency syndrome of cerebral infarction. ResultsRegarding the syndrome indicators, compared with the normal group, the mice in the model group had lower body weight, higher rectal temperature, lower limb motor ability and energy metabolism efficiency, lower ATP content, lower R, G and B values of the tongue surface, and lower speed of blood glucose regression(P<0.05, P<0.01). As for the disease indicators, compared with the normal group, the Bederson scores of the photochemical group and the STZ+photochemical group increased, the grip strength decreased, the SOD level decreased, and the levels of inflammatory factors increased(P<0.05). The results of metabolomics showed that a good separation pattern of components was observed among mice in each group, with significant differences in components. Identification of MS data revealed a total of 44 differential metabolites in mice with Qi and Yin deficiency syndrome of cerebral infarction. Among them, 32 metabolites were up-regulated, mainly including triglycerides, diglycerides, phospholipids, and ceramides. And 12 metabolites were down-regulated, mainly including amino acid and phosphate metabolites. Pathway enrichment analysis of the above differential metabolites indicated that the metabolic pathways were mainly enriched in folate biosynthesis, terpenoid skeleton biosynthesis, glycerophospholipid metabolism, vitamin B6 metabolism, glycerolipid metabolism and sphingolipid metabolism. These pathways were involved in multiple processes such as lipid transport, insulin resistance, and energy metabolism. ConclusionThe method of STZ injection combined with photochemical induction can successfully establish a mouse model of cerebral infarction with Qi and Yin deficiency syndrome, and intervene in vivo processes such as folate biosynthesis, glycerophospholipid metabolism, and glycerolipid metabolism.

Objective:To explore the influence of management mode of Deming cycle(plan,do,check,action,PDCA)combined with 6S management method on management effect of medical equipment in orthopedic department,and to improve the management quality for medical equipment in orthopedic department.Methods:In accordance with the combination of four stages of PDCA management and the six links(organization,tidying,cleaning,cleanliness,literacy and safety)of 6S management method,the medical equipment of orthopedic department was managed as stage by stage and link by link.Twelve using medical equipment in the orthopedic department of the Second Affiliated Hospital of Air Force Military Medical University were selected between 2022 and 2023.The management level between conventional management and management mode after the management mode of PDCA combined with 6S management mothed was implemented was compared,and the equipment fault and adverse event between within 87361 h before the management mode was used and within 87054 h after the management mode was used also were compared.The scores of satisfaction ratings of 15 medical staffs who involved in using equipment were investigated by using self-made questionnaire.Results:The scores of training assessment,regular maintenance,daily inspection,regular quality control and standardized use,and the total scores after used management mode of PDCA combined with 6S management method were respectively(18.87±0.66),(18.25±0.73),(18.74±0.69),(18.36±0.64),(18.89±0.54)and(92.11±4.20),all of which were higher than those before the management mode was implemented,and the differences of them were statistically significant(t=5.047,3.301,3.396,3.191,3.107,6.170,P<0.05).The standby time due to equipment fault and fault rate within 87054 h of using equipment after the management mode was implemented were respectively 262h and 0.30%,all of which were lower than those before the management mode was implemented,and the differences of them were statistically significant(x2=52.876,P<0.05).The incidence of adverse events of 12 equipment was 0.00%after the management mode was implemented,which was lower than that before it was implemented,and the difference was statistically significant(x2=4.800,P<0.05).The scores of 15 medical staffs on the performance,cleanliness,maintenance,consuming and technical support of equipment,and the total scores were respectively(18.41±1.11),(18.35±1.05),(18.58±0.87),(18.26±1.00),(18.77±0.89)and(92.21±4.12)scores after the management mode was implemented,which were higher than those before it was implemented,and the differences were statistically significant(t=5.257,4.939,5.429,3.191,4.705,9.858,P<0.05).Conclusion:The application of the management mode of PDCA combined with 6S management method in medical equipment management of orthopedic department can improve the management level for equipment,and reduce the incidences of equipment fault and adverse events in using equipment,and improve the satisfaction of medical staffs in using equipment.
