OBJECTIVE: Therapeutic angiogenesis has become a promising approach for treating ischemic heart disease (IHD). The present study aims to investigate the effects of Qishen Granule (QSG) on angiogenesis in myocardial ischemia (MI) and the potential mechanism. METHODS: In vivo study was conducted on rat model of myocardial infarction. QSG was performed daily at a dose of 2.352 g/kg for four weeks. Cardiac function was assessed by echocardiogram and pro-angiogenic effects were evaluated by Laser Doppler and CD31 expression. Oxygen-glucose deprivation (OGD) was applied in cultured human umbilical vein endothelial cells (HUVECs). Cell viability, wound healing and tube formation assay were used to test functions of HUVECs. ELISA and Western blots were used to assess protein expressions of bone morphogenetic protein 2-delta-like 4-notch homolog 1 (BMP2-Dll4-Notch1) signaling pathway. RESULTS: The results showed that QSG improved heart function, cardiac blood flow and microvessel density in myocardial ischemic rats. In vitro, QSG protected HUVECs by promoting the cell viability and tube formation. QSG upregulated bone morphogenetic protein-2 (BMP2) and downregulated delta-like 4 (Dll4) and notch homolog 1 (Notch1) expressions both in rats and HUVECs. CONCLUSION QSG protected against MI by promoting angiogenesis through BMP2-Dll4-Notch1 pathway. BMP2 might be a promising therapeutic target for IHD.

OBJECTIVE To compare the effect of traditional swab sampling method on etiological surveillance of in-fectious diseases for large-scale object surfaces in hospitals and validate the samples processing method based on pre-wet anti-static fabric and modified polyethylene glycol(PEG)precipitation enrichment technology so as to im-prove the capability of early warning of infectious diseases and optimize the environmental surveillance program in the hospitals.METHODS The on-site surveillance was carried out for 8 times in 3 public hospitals(Shenzhen Longgang People's Hospital,the Second People's Hospital of Longgang and Longgang Maternal and Child Health Hospital)from May 2024 to Mar.2025.Totally 23 types of respiratory tract pathogens(18 types of viruses,5 type of pathogenic bacteria)and 6 types of gastrointestinal tract pathogens were simultaneously detected by means of fluorescent quantitative polymerase chain reaction(PCR);the actual isolation rates,etiological spectrum and cycle threshold(Ct)value were compared.The acrylic plate added with standards of different loads of H1NI influ-enza viruses was used as model for laboratory evaluation.The minimum detection limit,sensitivity and repeatabili-ty were observed and compared between the methods.RESULTS The minimum detection limit of both methods was 6.0 × 104 copies/ml,however,the positive rate of nucleic acid testing of the pre-wet fabric method was 100.00％(3/3),higher than 33.33％(1/3)of the swab method;when the low viral load was 6.0× 105 copies/ml,the average concentration of viral nucleic acid of the pre-wet fabric method(X-Ct=36.59)was higher,with the re-peatability(CV=0.99％,＜3.14％)better.The results of the on-site surveillances showed that the total isolation rates of pathogens of the pre-wet fabric method ranged between 42.84％and 64.27％,higher than between 10.71％and 21.43％of the swab method,with the isolated pathogens more abundant,the Ct value lower(P＜0.05).CONCLUSION The pre-wet fabric sampling enrichment method integrated with anti-static fabric sampling and PEG enrichment technology shows higher sensitivity and stability in the etiological surveillance of large-scale object surfaces,raising the isolation rate.

Objective: To assess the dynamic changes of microcirculation at acupoints in patients with primary dysmenorrhea and cold congelation and blood stasis syndrome using laser speckle blood flow imaging. Methods: Patients with primary dysmenorrhea and cold coagulation and blood stasis syndrome (primary dysmenorrhea group, n=53) and healthy female college students(control group, n=57) who met the inclusion and exclusion criteria from October 2020 to July 2022 were enrolled at Hebei University of Chinese Medicine. On the premenstrual and first day of menstruation, a laser speckle blood flow imaging system was used to measure the microcirculation blood flow perfusion on the surface of acupoints related to the conception, thoroughfare, and governor vessels, and stomach, spleen, and bladder meridians in the abdomen and lumbosacral regions. The dynamic changes in microcirculation were calculated based on the difference in average blood flow perfusion at each acupoint before and after menstruation. Receiver operating curve (ROC) analysis was used to analyze the diagnostic efficacy of dynamic changes in microcirculation on the surface of each acupoint. The microcirculation sensitization rate of acupoints was calculated. Results: Compared with the control group, the dynamic changes in microcirculation at the following acupoints in the primary dysmenorrhea group were increased (P<0.05): conception vessel (Yinjiao[CV7], Qihai[CV6], Shimen[CV5], Guanyuan[CV4]); left thoroughfare vessel (left Huangshu[KI16], left Zhongzhu[KI15], left Siman[KI14], left Qixue[KI13], left Dahe[KI12], left Henggu[KI11]); left stomach meridian (left Tianshu[ST25], left Wailing[ST26], left Qichong[ST30]); left spleen meridian (left Daheng[SP15], left Fujie[SP14]); right thoroughfare vessel (right Huangshu[KI16], right Zhongzhu[KI15], right Siman[KI14], right Qixue[KI13], right Dahe[KI12], right Henggu[KI11]); right stomach meridian (right Wailing[ST26], right Daju[ST27], right Shuidao[ST28], right Guilai[ST29], right Qichong[ST30]); and right spleen meridian (right Fujie[SP14]). The area under the ROC curve of conception vessel (Yinjiao[CV7], Qihai[CV6], Shimen[CV5], Guanyuan[CV4]), thoroughfare vessel (right Siman[KI14], left Huangshu[KI16], right Qixue[KI13], right Zhongzhu[KI15], right Dahe[KI12], left Zhongzhu[KI15], left Siman[KI14], right Huangshu[KI16], left Qixue[KI13], right Henggu[KI11], left Henggu[KI11], left Dahe[KI12]); stomach meridian (left Tianshu[ST25], right Guilai[ST29], left Wailing[ST26], right Shuidao[ST28], right Daju[ST27], right Wailing[ST26], right Qichong[ST30], left Qichong[ST30]), and spleen meridian (left Daheng[SP15], left Fujie[SP14], right Fujie[SP14]) was 0.610-0.682 (P<0.05). Compared with the control group, the sensitization rate of some acupoints in the primary dysmenorrhea group increased (P<0.05). Conclusion With the onset of menstruation, the blood flow perfusion of some acupoints in the abdomen (thoroughfare, and conception vessels, and stomach and spleen meridians) of patients with primary dysmenorrhea and cold blood coagulation and blood stasis syndrome increased, and the status of acupoints changed from a resting state to an active state. These acupoints are sensitive in patients with primary dysmenorrhea and cold blood coagulation and blood stasis syndrome and have a certain diagnostic efficacy, providing a basis for further analyzing the efficacy and mechanism of acupuncture and moxibustion to treat primary dysmenorrhea with cold blood coagulation and blood stasis syndrome.

Objective:To explore the diagnostic value of serum soluble semaphorin 4D (sSema4D) and soluble CD40 ligand (sCD40L) in left ventricular hypertrophy (LVH) in patients with primary hypertension (EH).Methods:Eighty-four patients with EH combined with LVH admitted to Qingdao Hospital of Shandong First Medical University from December 2022 to December 2023 were prospectively selected as the study group, and 84 patients with EH and without LVH admitted to Qingdao Hospital of Shandong First Medical University during the same period were regarded as the control group. Enzyme linked immunosorbent assay was applied to detect the levels of sSema4D and sCD40L. Employing Pearson correlation coefficient, the study assessed the association between concentrations of sSema4D and sCD40L in serum and various echocardiographic measurements. A multivariate Logistic regression model was engaged to probe into the contributing factors for the development of LVH. ROC curve was plotted to analyze the diagnostic value of serum sSema4D and sCD40L for EH combined with LVH.Results:Serum sSema4D and sCD40L levels were significantly higher in the study group than in the control group: (8.56 ± 2.19) μg/L vs. (5.12 ± 1.43) μg/L, (4.02 ± 1.03) μg/L vs. (3.22 ± 0.98) μg/L, and the differences were statistically significant ( P<0.05). The duration of hypertension, LVEDD, IVSTD, LVPWT, and LVMI were significantly higher in the study group than in the control group: (7.33 ± 1.53) years vs. (4.26 ± 1.35) years, (50.28 ± 3.33) mm vs. (44.45 ± 3.76) mm, (11.64 ± 3.21) mm vs. (9.53 ± 2.89) mm, (12.45 ± 1.52) mm vs. (9.13 ± 0.98) mm, (126.11 ± 15.28) g/m 2 vs. (81.15 ± 11.31) g/m 2, and the differences were statistically significant ( P<0.05). According to Pearson correlation analysis, it was known that both serum sSema4D and sCD40L were positively correlated with LVEDD, IVSTD, LVPWT and LVMI ( r = 0.425 and 0.533, 0.612 and 0.436, 0.513 and 0.628, 0.589 and 0.618; P<0.05). Multivariate Logistic regression analysis showed that hypertension duration, LVEDD, IVSTD, LVPWT, LVMI, sSema4D, sCD40L were risk factors for LVH in EH patients ( P<0.05). According to the ROC curve, the AUC for diagnosing EH combined with LVH with serum sSema4D was 0.848, the AUC for diagnosing EH combined with LVH with serum sCD40L was 0.725, and the AUC for diagnosing EH combined with LVH with serum sCD40L was 0.888, the combination of sCD40L and sCD40L was superior to their respective individual diagnoses ( Z = 2.651 and 2.526, P<0.05). Conclusions:The serum levels of sSema4D and sCD40L in patients with EH combined with LVH are obviously elevated, which are influencing factors for the occurrence of EH combined with LVH. Combined testing of the two has high diagnostic value for EH combined with LVH.
