Compounds isolated from Epimedium include the total flavonoids of Epimedium , icariin, and its metabolites (icaritin, icariside I, and icariside II), which have similar molecular structures. Modern pharmacological research and clinical practice have proved that Epimedium and its active components have a wide range of pharmacological effects, especially in improving sexual function, hormone regulation, anti-osteoporosis, immune function regulation, anti-oxidation, and anti-tumor activity. To date, we still need a comprehensive source of knowledge about the pharmacological effects of Epimedium and its bioactive compounds on the male reproductive system. However, their actions in other tissues have been reviewed in recent years. This review critically focuses on the Epimedium , its bioactive compounds, and the biochemical and molecular mechanisms that modulate vital pathways associated with the male reproductive system. Such intrinsic knowledge will significantly further studies on the Epimedium and its bioactive compounds that protect the male reproductive system and provide some guidances for clinical treatment of related male reproductive disorders.

OBJECTIVE: Several epidemiological observational studies have related particulate matter (PM) exposure to Inflammatory bowel disease (IBD), but many confounding factors make it difficult to draw causal links from observational studies. The objective of this study was to explore the causal association between PM _2.5 exposure, its absorbance, and IBD. METHODS: We assessed the association of PM _2.5 and PM _2.5 absorbance with the two primary forms of IBD (Crohn's disease [CD] and ulcerative colitis [UC]) using Mendelian randomization (MR) to explore the causal relationship. We conducted two-sample MR analyses with aggregated data from the UK Biobank genome-wide association study. Single-nucleotide polymorphisms linked with PM _2.5 concentrations or their absorbance were used as instrumental variables (IVs). We used inverse variance weighting (IVW) as the primary analytical approach and four other standard methods as supplementary analyses for quality control. RESULTS: The results of MR demonstrated that PM _2.5 had an adverse influence on UC risk (odds ratio [ OR] = 1.010; 95% confidence interval [ CI] = 1.001-1.019, P = 0.020). Meanwhile, the results of IVW showed that PM _2.5 absorbance was also causally associated with UC ( OR = 1.012; 95% CI = 1.004-1.019, P = 0.002). We observed no causal relationship between PM _2.5, PM _2.5 absorbance, and CD. The results of sensitivity analysis indicated the absence of heterogeneity or pleiotropy, ensuring the reliability of MR results. CONCLUSION Based on two-sample MR analyses, there are potential positive causal relationships between PM _2.5, PM _2.5 absorbance, and UC.

【Objective】 To explore the risk factors for the production of anti-HLA antibodies in patients with hematological diseases before hematopoietic stemcell transplantation. 【Methods】 The results and clinical data of 1 008 patients with hematological diseases in our hospital who underwent anti-HLA antibody testing were collected by using Luminex technology platform before transplantation from 2016 to 2018 for statistical analysis. 【Results】 The total positive rate of anti-HLA antibodies in 1 008 patients was 24.08%. Multivariate analysis showed that independent risk factors associated with the production of anti-HLA antibodies included age≥30 years old(P=0.046, OR1.467, 95%CI1.007-2.136), time from disease diagnosis to antibody testing≥41 days(P=0.000, OR1.830, 95%CI1.306-2.565), initial platelet count<20×10⁹/L(P=0.020, OR1.543, 95%CI1.072-2.220), prior pregnancy(P=0.000, OR5.187, 95%CI3.689-7.293), transfusions before admission(P=0.001, OR1.762, 95%CI1.257-2.470)and total platelet transfusion volumes after admission≥30 U(P=0.000, OR2.352, 95%CI1.638-3.376). Age ≥30 years old(P=0.023, OR=1.839, 95%CI1.088-3.108)and prior pregnancy(P=0.042, OR=5.258, 95%CI1.062-26.038)are associated with the production of anti-HLA class Ⅰ and class Ⅱ antibodies, respectively. The time from disease diagnosis to antibody testing≥41 days(P=0.000, OR=2.873, 95%CI1.612-5.119), initial platelet count<20×10⁹/L(P=0.008, OR=2.164, 95%CI1.225-3.822), prior pregnancy(P=0.002, OR=6.734, 95%CI1.993-22.751), transfusions before admission(P=0.001, OR=2.746, 95%CI1.531-4.925)and total platelet transfusion volumes after admission>30 U(P=0.006, OR=3.459, 95%CI1.416-8.451)are associated with the production of anti-HLA class Ⅰ and Ⅱ antibodies. 【Conclusion】 Older age, longer course of disease, lower PLT count, history of pregnancy and blood transfusion, and higher total amount of PLT transfusion are risk factors which affect the production of anti-HLA antibodies.Therefore, it is advisable to test for anti-HLA antibodies according to the situation before transplantation, which is of great value in guiding donor selection, monitoring antibody changes and improving transplant prognosis.

AIM: To valuate the efficacy of 0.01% atropine for controlling myopia in children of different ages.METHOD: A randomized, double-blind, placebo control and single-center study was conducted. A total of 295 myopic children, aged 6～13 years, with myopia of -0.5D～-6.00D and astigmatism ≤2.0D, who admitted to our hospital from May 2019 to May 2020 were randomly assigned to experimental group(197 cases)and control group(98 cases)in a 2:1 ratio. Two groups were further divided into three subgroups according to age, 6～8 years old group(40/26 cases), 9～10 years group(84/34 cases), and 11～13 years group(73/38 cases). 0.01% atropine was administrated in the experimental group and placebo was administrated in the control group once before sleep. The changes of parameters were compared before and at 2wk, 3, 6, 9 and 12mo after treatment. Intraocular pressure, accommodation amplitude, best corrected distance and near visual acuity, pupil diameter and tear film were tested at 2wk. Cycloplegic refraction was assessed before treatment, and at 6 and 12mo after treatment.RESULTS: The spherical equivalent and axial length progression at 12mo after administration was -0.37±0.69D and 0.29±0.24mm in the experimental group, and -0.59±0.65D and 0.37±0.23mm in the control group(P=0.008, 0.006). In 6～8 years group, spherical equivalent and axial length progression between experimental and control group were not statistically significant(t=0.054, P=0.957; t=-0.623, P=0.536). In 9～10 years group, spherical equivalent and axial length progression between groups were statistically significant(t=2.056, P=0.042; t=-2.057 P=0.042). In 11～13 years group, spherical equivalent and axial length progression between groups were statistically significant(t=2.33, P=0.022; t=-2.424, P=0.017). The pupil was slightly dilated and the accommodation amplitude was decreased in experimental group, and the mean pupil diameter of the two groups was 3.94±0.79 and 3.16±0.48 mm respectively at 12mo after treatment(P<0.001). Other parameters and adverse event noted between groups were not statistically significant.CONCLUSIONS: 0.01% atropine is helpful to control the progression of myopia in children, which is well tolerated by adolescents. However, the effect of 0.01% atropine on the control of myopia for children aged 6～8 years is not enough. The findings suggest that increased concentration of atropine can be tried for 6～8 years old.

Objective To investigate the Gram-positive coccus resistance in nationwide's tertiary hospitals and understand the trend of antimicrobial resistance.Methods All the clinical isolates were collected from 19 hospitals and the minimal inhibitory concentrations(MICs)were tested using agar/broth dilution method recommended.Results A total of 1 974 pathogenic Gram-positive coccus from 19 tertiary hospitals in 19 cities nationwide over the period from July 2021 to June 2022 were studied.Based on the MIC results,the prevalence of methicillin resistant Stapylococcus aureus(MRSA)and methicillin resistant Stapylococcus epidermidis(MRSE)were 36.4％and 79.9％respectively.No vancomycin insensitivity Staphylococcus was detected.Staphylococcus aureus were 100％susceptibility to linezolid and teicoplanin.Antibiotic resistance rate of Enterococcus faecalis and Enterococcus faecium to ampicillin were 3.1％and 92.9％.The detectation rate of vancomycin resistant Enterococcus(VRE)was 1.6％.Nonsusceptibility rate of Enterococcus faecalis to linezolid was 32.2％,two consecutive monitoring rises and nonsusceptibility rate of Enterococcus faecium(12.5％)was also significantly increased.The prevalence of penicillin non-susceptible Streptococcus pneumoniae(PNSSP)was 0.8％based on non-meningitis and parenteral administration criterion,decrease of nearly 30 percentage points from the previous surveillance.While for cases of oral penicillin,the rate was 71.8％,showing similar to last time.The results indicated that the number of strains with higher MIC value of penicillin(MIC ≥4 mg·L-1)decreased significantly.There were no significant differences of resistance rates of Stapylococcus aureus,Stapylococcus epidermidis,Enterococcus faecalis,Enterococcus faecium and Streptococcus pneumoniae among various groups such as different department,age,or specimen source.Conclusion VRE detection ratio stablized at a relatively low level.The number of Streptococcus pneumoniae with higher MIC value of penicillin decreased significantly compared with the previous monitoring.The increase of linezolidin-insensitive Enterococcus was noteworthy.

Objective To investigate the Gram-negative bacteria resistance in nationwide's tertiary hospitals and understand the trend of antimicrobial resistance.Method All the clinical isolates were collected from 19 hospitals and the minimal inhibitory concentrations(MICs)were tested using agar/broth dilution method recommended.Results A total of 4 066 pathogenic isolates from 19 tertiary hospitals in 19 cities nationwide over the period from July 2021 to June 2022 were studied.Based on the MIC results,Escherichia coli and Klebsiella pneumoniae showed extended spectrum β-lactamase(ESBLs)phenotype rates of 55.0％and 21.0％,respectively,ESBLs phenotype rate of Klebsiella pneumoniae keep going down.The ratios of carbapenems resistance Klebsiella pneumoniae increased by 5 percentage points compared with the previous monitoring.Carbapenems,moxalactam,sitafloxacin,β-lactam combination agents,fosfomycin trometamol,and amikacin displayed desirable antibacterial activity against Enterbacterales,susceptibal rates were above 75％.In addition,tigacycline,omacycline,colistin and fluoxefin maintained good antibacterial activity against their respective effective bacteria/species,and the bacterial sensitivity rates by more than 80％.Resistance rates of Pseudomonas aeruginosa and Acinetobacter baumannnii to imipenem were 26.3％and 72.1％and multidrug-resistant(MDR)detection rates were 41.1％and 77.3％,extensively drug-resistant(XDR)were 12.0％and 71.8％,respectively.Comparison of drug resistance rates from different wards,ages and specimen sources indicated that the proportion of resistance in Klebsiella pneumoniae and Acinetobacter baumannii isolated from intensive care unit(ICU)were significantly higher than non-ICU.Carbapenem resistance rates of Klebsiella pneumoniae isolated from ICU were more than 35％.Resistance rates of Haemophilus influenzae isolated in children to β-lactam,macrolide,clindamycin and ESBLs detection rate in Klebsiella pneumoniae isolated from children were more than those from adults and the old people,so bacterial resistance in children is an important problem in China.Conclusion ESBLs detection rate of Escherichia coli increased slightly after years of continuous decline.The proportion of carbapenem resistant Pseudomonas aeruginosa was stable,but the resistance rate of Klebsiella pneumoniae and Acinetobacter baumannii to carbapenems was still increased,which should be paid more attention.

The increasing incidence of obesity and diabetes has made diabetic kidney disease （DKD） the main cause of chronic kidney disease and end-stage renal disease. Despite current pharmacological interventions for blood glucose control and renin-angiotensin system inhibition， the risk of kidney disease progression and complications remains high. At present， the pathogenesis of DKD has been clarified to be related to chronic inflammatory response， oxidative stress， glucose and lipid metabolism disorders， and hemodynamic abnormalities. According to recent studies， the programmed cell deaths （PCD） of renal intrinsic cells such as pyroptosis and necroptosis play a key role in the occurrence and development of DKD. Pyroptosis and necroptosis， the two newly discovered routes of PCD， can protect the hosts from being invaded by microbial pathogens， but their dysregulation is associated with multiple autoimmunity and autoinflammatory responses. Pyroptosis and necroptosis are closely interlinked and cross-regulated. Different from apoptosis， these two cellular suicide mechanisms cause membrane rupture and release of cell contents through their respective gasdermin D （GSDMD） and mixed lineage kinase domain-like protein （MLKL）， with damage-associated molecular patterns （DAMPs） and inflammatory cytokines like interleukin-1β （IL-1β） involved to trigger inflammation， and chronic inflammatory responses are key factors leading to the progression of DKD. Traditional Chinese medicine （TCM） has long been employed for the prevention and treatment of DKD and the resulting clinical outcomes are remarkable. TCM has been proved to exert a protective effect against DKD by affecting the expression of nucleotide oligomerization domain-like receptor protein 3 （NLRP3） inflammasome， receptor-interacting protein kinase 3 （RIPK3）， and MLKL. This paper reviewed the relationship of pyroptosis and necroptosis with DKD and its intervention with TCM.
