Objective:To investigate the impact of QiliQiangXin Capsules on ventricular remodeling and cardiac contraction and relaxation function in aging rats with heart failure following myocardial infarction.Methods:From August 2022 to August 2023, a total of 30 old rats were randomly assigned to three groups: sham-operated group, model group, and treatment group, with 10 rats in each group selected through a digital lottery method.The model and treatment groups were created by ligating the anterior descending branch of the left coronary artery.The rats in the treatment group received daily administration of Astragalosa hebecarpa Drabanemerosa Strong Heart Capsule(1.0 g/kg)via gavage after 4 weeks.After the 4-week drug administration period, echocardiography was performed to measure various parameters including left ventricular end-diastolic internal diameter(LVIDd), left ventricular end-systolic internal diameter(LVIDs), left ventricular ejection fraction(LVEF), left ventricular anterior wall myocardial thickness(LVAWd), mitral valve early diastolic peak flow velocity(E peak), and early diastolic velocity of mitral annulus(e peak)detected by tissue Doppler(TDI). The E/e value was calculated based on these measurements.Additionally, serum levels of B-type brain natriuretic peptide(BNP), matrix metalloproteinase 2(MMP-2), matrix metalloproteinase 9(MMP-9), and tumor necrosis factor(TNF-α)were measured using enzyme-linked immunosorbent assay(ELISA). Hematoxylin-eosin(HE)staining was employed to observe the morphological changes in myocardial tissue.Results:Compared to rats in the model group, rats in the treatment group exhibited lower left ventricular internal dimension at end-diastole(LVIDd)(9.1±0.6 mm vs.11.4±0.8 mm, P<0.01), lower left ventricular internal dimension at end-systole(LVIDs)(5.9±0.8 mm vs.8.7±0.9 mm, P<0.01), lower E/e ratio(13.4±2.0 vs.16.3±2.8, P<0.05), higher left ventricular ejection fraction(LVEF)(68.8±7.1% vs.52.0±8.4%, P<0.01), and elevated left ventricular anterior wall thickness at end-diastole(LVAWd)(1.5±0.2 mm vs.1.2±0.3 mm, P<0.05). In addition, compared to rats in the model group, the treatment group showed a decrease in brain natriuretic peptide(BNP)(0.26±0.04 μg/L vs.0.34±0.05 μg/L, P<0.01), decreased matrix metalloproteinase-2(MMP-2)(3697.0±857.7 μg/L vs.4719.5±703.5 μg/L, P<0.01), decreased matrix metalloproteinase-9(MMP-9)(87.3±13.8 μg/L vs.116.5±9.6 μg/L, P<0.01), decreased tumor necrosis factor-alpha(TNF-α)(165.3±36.9 μg/L vs.269.8±35.0 μg/L, P<0.01), and lower TNF-α levels(165.3±36.9 μg/L vs.269.8±35.0 μg/L, P<0.01). Histological examination using hematoxylin and eosin(HE)staining revealed that the treatment group had less severe cardiac myocyte arrangement disorder and inflammatory reaction compared to the model group. Conclusions:Qiliqiangxin Capsules were found to effectively delay ventricular remodeling and improve myocardial contraction and relaxation function in aging rats with heart failure after acute myocardial infarction.

Hypertensive intracerebral hemorrhage(HICH)is a disease with a rapid onset,rapid progression,high mortality rate,and long-term impact on the ability to function.Non-contrast agent-based CT(NCCT)is a common method for evaluating and identifying HICH.Recent radiomics in image processing and machine learning(ML)have enabled the extraction of high-dimensional feature information from medical images,which can be used to rapidly and accurately diagnose HICH and predict its course of disease.The paper describes the application of radiomics and ML techniques in HICH diagnosis and treatment,and identifies possible directions for future research.

Objective:To investigate the prevalence and molecular characteristics of Escherichia coli ( E. coli) producing a novel Shiga toxin 2k subtype in goat in Lanling county, Shandong province. Methods:In November 2019, 512 goat fecal samples were collected from different households in Lanling county, Shandong province. After enriched with EC broth, stx-positive samples were detected by PCR and inoculated in CHROMagar? ECC agar and CHROMagar? STEC agar. The whole genomes of stx-positive strains were sequenced. Based on the genomic senquences, the stx subtype, serotype, multi-locus sequence type and virulence genes of each strain were analyzed. Results:Eighty-six strains of Shiga toxin-producing E. coli (STEC) were isolated from 512 goat fecal samples. Five stx subtypes were identified and 37 strains were positive for stx2k. The 86 STEC strains belonged to 20 O∶H serotypes and 18 different sequence types (STs). Conclusions:STEC strains circulating in goats in Lanling county, Shandong province were heterogeneous in stx subtypes, serotypes and virulence gene profiles, and a certain proportion of strains producing a novel Shiga toxin 2k subtype were detected.

To explore the development tendency and major influential factors of traditional Korean medicine (TKM) resource and service by statistics analysis. Data are mainly from the Yearbook of Traditional Korean Medicine (2009-2015). Ministry of Health and Welfare Statistical Yearbook 2016, and the Ministry of health and welfare practicing qualification management system. This article analyzed the related indicators, such as the average annual growth rates and the proportion in the national medical system. From 2006 to 2015, the average annual growth rate of the number of TKM hospital and TKM clinics were 7.0％ and 3.2％ separately; the average annual growth rate of TKM doctor and TKM pharmacists were 4.3％ and 10.0％ separately; the average annual growth rate of the number of beds in TKM institutions were 9.3％; and the average annual growth rate of the number of applications for outpatient and inpatient reimbursement for medical insurance of TKM institutions were 12.3％ and 20.5％ separately. From 2006 to 2015, the resources and services of TKM presented an increasing tendency, and the accessibility of TKM resource and service was enhanced. It is suggested that China should use reference from the aspects of strengthening policy, expanding the sources of capital investment, and expanding the coverage of medical insurance.

For the past several decades, the infectious disease profile in China has been shifting with rapid developments in social and economic aspects, environment, quality of food, water, housing, and public health infrastructure. Notably, 5 notifiable infectious diseases have been almost eradicated, and the incidence of 18 additional notifiable infectious diseases has been significantly reduced. Unexpectedly, the incidence of over 10 notifiable infectious diseases, including HIV, brucellosis, syphilis, and dengue fever, has been increasing. Nevertheless, frequent infectious disease outbreaks/events have been reported almost every year, and imported infectious diseases have increased since 2015. New pathogens and over 100 new genotypes or serotypes of known pathogens have been identified. Some infectious diseases seem to be exacerbated by various factors, including rapid urbanization, large numbers of migrant workers, changes in climate, ecology, and policies, such as returning farmland to forests. This review summarizes the current experiences and lessons from China in managing emerging and re-emerging infectious diseases, especially the effects of ecology, climate, and behavior, which should have merits in helping other countries to control and prevent infectious diseases.

Objective To grasp the current situation and trend of health personnel development in public TCM hospitals through the analysis of health personnel statistics data of public TCM hospitals in China; To provide decision-making references for management departments. Methods Data were from the National Health and Family Planning Commission Statistical Information Center. This article analyzed staff number, the average speed of development, the average annual growth rate, health staff age, academic qualifications and job titles and other indicators of TCM public hospitals during 2010-2015. Results From 2010 to 2015, there was an annual increasing tendency of the number of TCM health personnel, and the average annual growth rate was 5.9％, but the growth of the percentage of the TCM health personnel to the total health personnel was only 0.3％. In 2015, the proportion of TCM health personnel was less than 50％; the doctor-to-nurse ratio was 1:1.18; the educational level of postgraduate and undergraduate were 14.0％ and 48.0％ respectively, less than the average level of national hospitals. Conclusion From 2010 to 2015, there is an increasing tendency of the TCM health personnel of public TCM hospitals, but the proportion of TCM health personnel is low. The doctor-to-nurse ratio is reasonable gradually, but there is still a gap compared with the average level of the national hospitals. The average age of technical health personnel tends to be younger. The proportion of high educational level health personnel is increasing, but the proportion of senior technical position is reduced. The management departments should take appropriate measures to promote the rational allocation of human resources and development of TCM hospitals.

Objective To compare the field-matching techniques and dosimetric characteristics in the target area of testicular seminoma including the abdominal and pelvic cavities between direct aperture optimization intensity modulated radiation therapy (DAO-IMRT) and 3D conformal radiation therapy (3D-CRT),and to analyse the advantages and disadvantages of DAO-IMRT.Methods DAO-IMRT and 3D-CRT plans were designed with Pinnacle treatment planning system for 7 testicular seminoma patients,and the characteristics of both the irradiation methods were analyzed and evaluated by means of the parameters like dose homogeneity indexes,dose volume histograms and etc.Results DAO-IMRT had the hot and cold volumes in the target areas both significantly smaller than those by 3D-CRT,while the conformity index and homogeneity index superior to those by 3D-CRT.The mean doses (Dmean) by DAO-IMRT of the organs at risk (OAR) except the left femur head were all lower than those by 3D-CRT,aud the V15 values of liver,double kidney,small intestine and rectum by DAO-IMRT were statistically lower than those by 3D-CRT (P＜0.01).3D-CRT had the V5 values of OAR all lower than those by DAO-IMRT,in which the differences of double kidney,small intestine,bladder,left femur head and normal tissues were significant statistically (P＜0.05).The monitor units by DAO-IMRT roughly doubled when compared with those by 3D-CRT,and the difference was also significant (P＜0.01).Conclusion DAO-IMRT with easy operation and high reliability can avoid the connection of fields in the target area of testicular seminoma,and is superior to 3D-CRT in dosimetry.
