The accumulation of uremic toxins such as urea nitrogen, blood creatinine, and uric acid of patients with renal failure in vivo would lead to aggravated kidney damage. In this study, coated aldehyde oxy-starch (CAO) was used as an adsorbent to investigate its in vitro adsorption performance on renal failure indexes for urea, indoxyl sulfate (INS), monomethylamine (MMA), dimethylamine (DMA), uric acid (UA), and creatinine (Cr). The effects of variables such as pH, temperature, concentration, dosage, and time on the adsorption capacity of CAO were systematically investigated, employing analytical techniques of high-performance liquid chromatography (HPLC) and gas chromatography (GC). The results revealed that CAO exhibited a strong adsorption capacity for urea, INS, and MMA, alongside a moderate adsorption capacity for DMA, UA, and Cr. The adsorption kinetics and thermodynamic studies indicated that the adsorption of urea and UA by CAO were fitted in pseudo-first-order kinetics, and the adsorption isotherm aligned with the Freundlich adsorption model. The enthalpy change ΔH of urea in adsorption was in the range of 40 to 60 kJ·mol^-1, which demonstrated the presence of strong adsorption force due to the interactions of coordinating groups. The ΔH of UA was greater than 80 kJ·mol^-1, indicating the generation of chemical bonds during the adsorption. Both of them, Gibbs free energy ΔG was less than 0, within the range of -20 to 0 kJ·mol^-1, suggested that the adsorption of urea and UA by CAO occurred spontaneously as physical adsorption process. The adsorption entropy ΔS of urea and UA was > 0, which indicated an increase in entropy throughout the adsorption. The infrared spectroscopygram showed the formation of a chemical bond, specifically the imine bond, following the adsorption of urea by CAO, thereby indicating a chemical reaction during the adsorption. This study elucidates the adsorption mechanism of CAO on various indexes of renal failure, providing a scientific basis for its clinical usage.

Leonurine(SCM-198)was discovered as one of the active constituents of the Herba Leonuri(HL).Now it can be artificially synthesized.Several recent researches has proven that it exhibits anti-inflammatory effect in several systems in animal models and cell culture in vitro.The key mechanism involves downgrading the activity of nuclear transcription factor-κB(NF-κB),thereby inhibiting the phosphorylation of several signal pathways such as PI3K/Akt,MAPK,ERK,and JNK,or upregulating the activity of Nrf2 related pathways,resulting in downregulated expression of inflammatory cytokines such as tumor necrosis factor-α(TNF-α),IL-1β,IL-2,IL-6,IL-8,inducible nitric oxide synthase(iNOS),cyclooxygenase-2(COX-2),chemokines,adhesion molecules,etc.Owing to the advantages of high safety and efficiency,the ease of administration,as well as its effectiveness in many organs and systems,leonurine has a widely prospect for future research and clinical applications.This article reviews the progress in the fundamental research of leonurine in multiple inflammation-related disease,and it could be expect to offer new possibilities for the treatment of these disease.

Objective To investigate the anti-atherosclerotic mechanism of herbal cake-separated moxibustion.Methods Twenty-four New Zealand purebred male rabbits were randomly divided into normal group,model group,herbal cake-separated moxibustion group and Atorvastatin group,with 6 rabbits in each group.Except for the normal group,the rabbits in the other groups were fed with high-fat diet mixed with Propylthiouracil(PTU)method to construct an atherosclerosis model.At the same period of modeling,corresponding intervention was given.After 12 weeks,the levels of serum total cholesterol(TC),triglyceride(TG)and low density lipoprotein cholesterol(LDL-C)were detected.The pathological changes of rabbit aortic tissue were observed by hematoxylin-eosin(HE)staining.The levels of serum tumor necrosis factor α(TNF-α),interleukin 6(IL-6)and interleukin 10(IL-10)were detected by enzyme-linked immunosorbent assay(ELISA).The contents of phosphatidylinositol 3-kinase(PI3K),phosphorylated protein kinase B(p-AKT)and phosphorylated mammalian target of rapamycin(p-mTOR)in myocardial tissue were detected by Western Blot.Results Compared with the normal group,the serum levels of TC,TG and LDL-C in the model group were significantly increased(P＜0.001),the aortic vascular endothelial structure was significantly damaged,the serum levels of TNF-α and IL-6 were increased(P＜0.001),the serum level of IL-10 was decreased(P＜0.01),and the protein expression levels of PI3K,p-AKT and p-mTOR in myocardial tissue were significantly decreased(P＜0.05 or P＜0.01).Compared with the model group,the above indexes in the herbal cake-separated moxibustion group and the Atorvastatin group were significantly improved(P＜0.05 or P＜0.01 or P＜0.001).Compared with the Atorvastatin group,the contents of TG and LDL-C in the herbal cake-separated moxibustion group were increased(P＜0.01),and other indicators did not change significantly(P＞0.05).Conclusion The mechanism of anti-atherosclerosis of herbal cake-separated moxibustion may be related to the activation of PI3K/AKT/mTOR signaling pathway and the regulation of the expressions of inflammatory mediators TNF-α,IL-6 and IL-10.

The current situation of childrearing in the elderly and low birth rate showed that the prevention and treatment of infertility risk caused by the decline of male reproductive function are increasingly becoming prominent.The decline of male reproductive function is closely related to the hypothalamic-pituitary-gonadal axis,oxygen free radicals,blood-testis barrier,and the apoptosis of spermatogenic cells.Traditional Chinese medicine believes that the kidney stores essence and is in charge of reproduction,and the decline of reproductive function is closely related to the imbalance of yin and yang of the kidney.Therefore,kidney-supplementing method is helpful for treating the decline of reproductive function caused by kidney deficiency.Kidney-supplementing prescriptions were effective on systematically regulating the function of the hypothalamic-pituitary-gonadal axis,thus to significantly delay the decline of reproductive function,were effective on removing excessive oxygen free radicals in the body and protecting cells from oxidative damage,and were effective on improving spermatogenesis by restoring the blood-testis barrier and regulating the apoptosis of spermatogenic cells.The representative kidney-supplementing prescriptions for improving the decline of reproductive function caused by kidney deficiency include Wuzi Yanzong Pills,Shenqi Pills,Yougui Pills,Liuwei Dihuang Pills,Zuogui Pills and Guilu Erxian Soft Extract.The above formulas presented no single therapeutic mechanism but multiple-way,multiple-level and multiple-target mechanism,and the formulas can comprehensively regulate the internal environment of the body,so as to achieve the purpose of improving male reproductive function.The kidney-supplementing therapy of traditional Chinese medicine plays an irreplaceable role in the treatment of male reproductive function decline.The in-depth study of its therapeutic mechanism will provide guide for clinical practice and will supply theoretical basis for improving male reproductive function decline.

In the progression of end-stage liver disease,the incidence of sleep disorders in patients with liver cirrhosis is high.Currently,western medicine treatment has obvious liver and kidney damage and adverse reactions after discontinuation,which affects the therapeutic effect.Cirrhosis and sleep disorders can be separately attributed to the category of"abdominal mass"and"insomnia"in traditional Chinese medicine.The"abdominal mass"is caused by the disorder of liver and spleen qi movement,as well as the obstruction of phlegm-dampness and blood stasis.In the development of"abdominal mass",the liver failed in ensuring free movement of qi,the spleen failed in transportation and transformation,liver yin and liver blood became insufficiency and the imbalance of yin and yang in the zang-fu organs became imbalanced,and then the ethereal soul depart from the housing,which leads to"insomnia"as an outward manifestation.Professor ZHOU Xiao-Zhou focuses on the concept of qi and blood,and points out that the pathogenesis of sleep disorder in cirrhosis is characterized by liver stagnation and spleen deficiency.He proposed that the treatment principle is to regulate the liver and spleen simultaneously,as well as to nourish the heart and calm the mind.Professor ZHOU has developed Ganyinghua Anshen Formula for treating sleep disorders in cirrhosis,which is derived from the modification of Xiangsha Liujunzi Decoction,and is composed of 14 Chinese medicines of vinegar-prepared Cyperi Rhizoma,Amomi Fructus,Coicis Semen,Dioscoreae Rhizoma,bran-fried Atractylodis Macrocephalae Rhizoma,Galli Gigerii Endothelium Corneum,Gardeniae Fructus,Codonopsis Radix,Salviae Miltiorrhizae Radix et Rhizoma,Citri Reticulatae Pericarpium,Sclerotium Poriae Pararadicis,Longan Arillus,Albiziae Cortex,and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle.The formula has achieved remarkable clinical effect.The clinical experience of Professor ZHOU Xiao-Zhou for treating sleep disorders in cirrhosis through regulating the liver and spleen simultaneously will provide a reference for its clinical treatment with traditional Chinese medicine.

Objective:To explore the intervention effects of repetitive transcranial magnetic stimulation on cognitive function of schizophrenia patients with methods using meta-analysis.Methods:CNKI,Wanfang Data,VIP,PubMed,Web of Science,the Cochrane Library and Embase were searched for randomized controlled trials of repetitive transcranial magnetic stimulation on cognitive function in schizophrenia.Quality assessment was per-formed with the Cochrane Handbook for Systematic Reviews.Effect sizes and heterogeneity were assessed using RevMan 5.3.Results:A total of 31 randomized controlled trials(2 421 patients)were included in this study.Meta-analysis showed that rTMS improved cognitive function in schizophrenia patients(SMD=0.73).Subgroup analyses showed that intervention intensity was less than or equal to 100％RMT,the intervention frequency was 1 Hz,the intervention time was lasted at least 20 min/time,and the intervention period was four weeks,the effect of rTMS was better.Subgroup analyses showed that rTMS was more effective in improving for patients with durations of 5 to 10 years.Conclusion:rTMS has more significant improvement effects on cognitive function in schizophrenia pa-tients.It is recommended to set the intervention intensity 100％RMT,the intervention frequency of 1 Hz,the in-tervention time ≥20 min,and the intervention period of 4 weeks in the clinic.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％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)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed 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 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

"Rooted in agriculture,rural areas,and farmers;Focused on integration"is an important gripper for Henan College of Animal Husbandry Economics to serve the development of regional agricul-ture and animal husbandry industries for high-level application-oriented universities.The courses of bio-chemistry and molecular biology are the foundational courses for agricultural majors in our school,and are an important carrier for the integration of science and technology in the construction of new agricultural science.In order to achieve the ideological and political goals of the curriculum under the background of the new agricultural curriculum,the course team has built a training platform for students'"agriculture,rural areas,and farmers"sentiments from the aspects of disciplinary development history,practical appli-cation of agriculture,rural areas,alumni excellent cases,ecological civilization,professional ethics,and bioethics through the condensation of ideological and political cases;In the arrangements of ideological and political cases and practical project,industry development,agriculture,rural areas,teacher re-search,school enterprise cooperation projects,and student independent innovation projects were connect-ed and integrated to establish a"fusion"platform for student knowledge application,thereby achieving the sentiment cultivation of students'"rooted in agriculture,rural areas,and farmers"and the enhance-ment of their integration capability.During the teaching process,blended online and offline teaching was applied to transform single classroom teaching into full cycle participation in talent cultivation.By integra-ting ideological and political elements into online tasks before class and teaching in the"six stages"of class and the second classroom after class,ideological and political goals were achieved through challeng-ing,advanced,and innovative knowledge applications.Through curriculum reform,the employment rate of students in the frontline of agriculture,rural areas,and farmers has significantly increased,and their ability to solve the problems of agriculture,rural areas and farmers through disciplinary integration has been effectively improved.This has successfully enhanced their awareness of serving agriculture,rural ar-eas,and farmers,strengthened their professional thinking,and stimulated their endogenous motivation to use curriculum knowledge in practice.

Objective To investigate the amplitude-integrated electroencephalography(aEEG)monitoring results of hospitalized neonates in plateau areas.Methods A retrospective analysis was conducted on 5 945 neonates who were admitted to the Department of Neonatology,Kunming Children's Hospital,and received aEEG monitoring from January 2020 to December 2022.According to the aEEG monitoring results,they were divided into a normal aEEG group and an abnormal aEEG group.The incidence rate of aEEG abnormalities was analyzed in neonates with various systemic diseases,as well as the manifestations of aEEG abnormalities and the consistency between aEEG abnormalities and clinical abnormalities.Results Among the 5 945 neonates,the aEEG abnormality rate was 19.28%(1 146/5 945),with an abnormality rate of 29.58%(906/3 063)in critically ill neonates and 8.33%(240/2 882)in non-critically ill neonates(P<0.05).The children with inherited metabolic diseases showed the highest aEEG abnormality rate of 60.77%(79/130),followed by those with central nervous system disorders[42.22%(76/180)]and preterm infants[35.53%(108/304)].Compared with the normal aEEG group,the abnormal aEEG group had significantly lower age and gestational age,as well as a significantly lower birth weight of preterm infants(P<0.05).Among the 1 146 neonates with aEEG abnormalities,the main types of aEEG abnormalities were sleep cycle disorders in 597 neonates(52.09%),background activity abnormalities in 294 neonates(25.65%),and epileptiform activity in 255 neonates(22.25%),and there were 902 neonates(78.71%)with abnormal clinical manifestations.The sensitivity and specificity of aEEG monitoring for brain function abnormalities were 33.51%and 92.50%,respectively.Conclusions In plateau areas,there is a relatively high rate of aEEG abnormalities among hospitalized neonates,particularly in critically ill neonates and those with smaller gestational ages and younger ages,suggesting a high risk of brain injury.Therefore,routine aEEG monitoring for the hospitalized neonates can help with the early detection of brain function abnormalities,the decision-making in treatment,and the formulation of brain protection strategies.
