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 monitor the susceptibility of clinical isolates to antimicrobial agents in healthcare facilities in major regions of China in 2023.Methods Clinical isolates collected from 73 hospitals across China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2023 Clinical & Laboratory Standards Institute (CLSI) breakpoints.Results A total of 445199 clinical isolates were collected in 2023,of which 29.0％ were gram-positive and 71.0％ were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species (excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi) (MRSA,MRSE and MRCNS) was 29.6％,81.9％ and 78.5％,respectively.Methicillin-resistant strains showed significantly higher resistance rates to most antimicrobial agents than methicillin-susceptible strains (MSSA,MSSE and MSCNS).Overall,92.9％ of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 91.4％ of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis had significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 93.1％ in the isolates from children and and 95.9％ in the isolates from adults.The resistance rate to carbapenems was lower than 15.0％ for most Enterobacterales species except for Klebsiella,22.5％ and 23.6％ of which were resistant to imipenem and meropenem,respectively .Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.6％ to 10.0％.The resistance rate to imipenem and meropenem was 21.9％ and 17.4％ for Pseudomonas aeruginosa,respectively,and 67.5％ and 68.1％ for Acinetobacter baumannii,respectively.Conclusions Increasing resistance to the commonly used antimicrobial agents is still observed in clinical bacterial isolates.However,the prevalence of important crabapenem-resistant organisms such as crabapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a slightly decreasing trend.This finding suggests that strengthening bacterial resistance surveillance and multidisciplinary linkage are important for preventing the occurrence and development of bacterial resistance.

Objective:To explore the association between weight change from age 20 to middle age and diabetes risk.Methods:A total of 10 104 residents over 40 years old were recruited in Guangzhou. The final analysis data set is a cohort of 6 272 patients from the REACTION study. Quartile of weight changes from age 20 to middle-age was used as an independent variable to explore its association with newly diagnosed diabetes. Simple and multivariable logistic regression analysis were used to calculate OR and 95% CI. Results:The prevalence of newly diagnosed diabetes in study cohort was 15.7%. Weight changes from age 20 to middle-age was significantly higher in diabetes group( P<0.001). Logistic regression analysis found in general population and overweight people [24.0≤body mass index(BMI)<28.0 kg/m 2], after adjusting for gender, age, educational level, family history of diabetes, drinking, SBP, waist circumference, cholesterol, high-density lipoprotein-cholesterol(HDL-C), TG, ALT, AST, the risk of diabetes increased in line with the magnitude of weight change( P=0.081). While in group of lean, normal and obese adult, no significant association has been found. Conclusion:The risk of diabetes increased with weight change in general population and overweight people, indicating that weight change in adults after age of 20 was positively associated with diabetes. It is suggested the importance of weight management in the prevention of dialetes.

The ensemble empirical mode decomposition (EEMD) can be used to overcome the mode mixing problem of empirical mode decomposition (EMD) effectively. The EEMD method and Hilbert-Huang Transform (HHT) can be used to analyze pulse signals of Traditional Chinese Medicine (TCM). The amplitudes of the added white noise were about 0.1 and 0.2 time standard deviation of the investigated signal respectively. The difference of average frequency and average energy of every mode between normal pulse, slippery pulse, wiry pulse and wiry-slippery pulse were demonstrated based on different amplitudes of the added white noise. The results showed that it is more in line with clinical practice when the amplitude of the added white noise is about 0.2 time standard deviation of the investigated signal.

OBJECTIVE: To study the inhibitory effects of short hairpin RNA (pshLMP1) combined with DNAzyme or alone on latent membrane protein-1 (LMP1)expression in HNE1 cell lines. METHOD: The pshLMP1 and DNAzymes were co-transfected with pEGFP-N1-1158 (a expression vector encoding LMP1 and EGFP fusion protein) into HNE1 cells, divided into 4 groups as positive control, RNA interference, combining and DNAzyme groups. The green fluorescence were analyzed and then the mRNA and protein of LMP1 gene were detected. RESULT: The HNE1 cells expressing green fluorescence in combining group were significantly less than that in RNA interference group (P < 0.01); The inhibition efficiency of green fluorescence in combining group were 86. 31% Wp 88.88% ,which were higher than that in RNA interference group with 75.15%. The detection of LMP1 mRNA and proteins showed that combining group had a higher inhibition ability. CONCLUSION Combining gene therapy with pshLMP1 and DNAzyme is superior to pshLMP1 alone to inhibit LMP1 gene expression.

OBJECTIVE: To detect and analyze the EBV-LMP1 gene N terminus XhoI-site mutation and C terminus 30 bp deletion in plasma of patients with nasopharyngeal carcinoma (NPC) in Chongqing of China. METHOD: DNA extraction and PCR amplification was used in plasma of 48 NPC patients and 40 control non-NPC cases from Chongqing of China. All the PCR production of N terminus was digested by enzyme XhoI, then segregated in 8% PAGE. All- the PCR production of C terminus was segregated in 8% PAGE too. Compared with B95-8 cell, some of the PCR production were sequenced and analyzed with software. RESULT: LMP1 was amplified successfully from 48 of 48 NPC cases (100%) and from 38 of 40 non-NPC cases (95%) by PCR, but none of LMP1 XhoI-site mutation and none of 30 bp deletion was found by digesting, segregating and Sequencing. CONCLUSION EBV-LMP1 gene N terminus XhoI-site and C terminus 30 bp deletion have no mutation in plasma of NPC or non-NPC cases in Chongqing of China. The precise relationship of EBV-LMP1 gene mutation or deletion with NPC pathogenesis needs further investigation.
