Objective To investigate the changing distribution and antibiotic resistance profiles of clinical isolates of Staphylococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Staphylococcus according to the unified protocol of CHINET(China Antimicrobial Surveillance Network)using disk diffusion method and commercial automated systems.The CHINET antimicrobial resistance surveillance data from 2015 to 2021 were interpreted according to the 2021 CLSI breakpoints and analyzed using WHONET 5.6.Results During the period from 2015 to 2021,a total of 204,771 nonduplicate strains of Staphylococcus were isolated,including 136,731(66.8％)strains of Staphylococcus aureus and 68,040(33.2％)strains of coagulase-negative Staphylococcus(CNS).The proportions of S.aureus isolates and CNS isolates did not show significant change.S.aureus strains were mainly isolated from respiratory specimens(38.9±5.1)％,wound,pus and secretions(33.6±4.2)％,and blood(11.9±1.5)％.The CNS strains were predominantly isolated from blood(73.6±4.2)％,cerebrospinal fluid(12.1±2.5)％,and pleural effusion and ascites(8.4±2.1)％.S.aureus strains were mainly isolated from the patients in ICU(17.0±7.3)％,outpatient and emergency(11.6±1.7)％,and department of surgery(11.2±0.9)％,whereas CNS strains were primarily isolated from the patients in ICU(32.2±9.7)％,outpatient and emergency(12.8±4.7)％,and department of internal medicine(11.2±1.9)％.The prevalence of methicillin-resistant strains was 32.9％in S.aureus(MRSA)and 74.1％in CNS(MRCNS).Over the 7-year period,the prevalence of MRSA decreased from 42.1％to 29.2％,and the prevalence of MRCNS decreased from 82.1％to 68.2％.MRSA showed higher resistance rates to all the antimicrobial agents tested except trimethoprim-sulfamethoxazole than methicillin-susceptible S.aureus(MSSA).Over the 7-year period,MRSA strains showed decreasing resistance rates to gentamicin,rifampicin,and levofloxacin,MRCNS showed decreasing resistance rates to gentamicin,erythromycin,rifampicin,and trimethoprim-sulfamethoxazole,but increasing resistance rate to levofloxacin.No vancomycin-resistant strains were detected.The prevalence of linezolid-resistant MRCNS increased from 0.2％to 2.3％over the 7-year period.Conclusions Staphylococcus remains the major pathogen among gram-positive bacteria.MRSA and MRCNS were still the principal antibiotic-resistant gram-positive bacteria.No S.aureus isolates were found resistant to vancomycin or linezolid,but linezolid-resistant strains have been detected in MRCNS isolates,which is an issue of concern.

To evaluate the feasibility and safety of suprapubic three-arm robot-assisted laparoscopic radical prostatectomy (STA-RLRP). Fifteen patients with prostatic cancer underwent STA-RLRP. All the 15 procedures were completed successfully, without the need for ancillary trocars or additional instruments. No patient required conversion to standard laparoscopy or open surgery. STA-RLRP is feasible and safe with good short-term tumor control, satisfactory recovery of urinary control function and good cosmetic outcome, which is worthy of clinical application.

Recently p75 neurotrophin receptor (p75NTR) has been found to play a critical role in the pathology of neurodegen¬erative! diseases including Alzheimer's disease (AD) , Parkin¬son' s disease ( PI)), Huntington's disease ( HI)) , amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS).This arti¬cle reviews the research progress of p75NTR in regulating neuron apoptosis, axon degeneration and cognitive impairment, explo¬ring the application of p75NTR as a potential therapeutic target for the treatment of neurodegenerative diseases.

In recent years， the incidence of neurological diseases has been increasing year by year. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of neurological disorders， identify the breakthrough point of integrating TCM with western medicine， and further standardize the clinical diagnosis and treatment of TCM， the China Association of Chinese Medicine organized neurologists in TCM and western medicine to carry out in-depth discussion on the neurological diseases responding specifically to TCM and integrated TCM and western medicine， such as stroke， headache， vertigo， multiple sclerosis， and epilepsy， aiming to formulate a well-recognized and integrated treatment protocol for TCM and western medicine and improve the efficacy of neurological disorders. Furthermore， the treatment suggestions of the corresponding diseases in TCM and western medicine were proposed to provide references for clinical practice and scientific research.

The purpose of the study is to analyze the outcomes of randomized controlled trial(RCT) of Chinese herbal medicine formula(CHMF) in the treatment of vascular cognitive impairment caused by cerebral small vessel disease(CSVD-VCI), and provide suggestions for future studies in this field. Three English databases, four Chinese databases, and two online registration websites of clinical trials were searched with use of the search strategy established in advance. Relevant RCTs published in recent ten years were screened, and necessary information was extracted to assess the risk of bias and analyze the outcomes of these RCTs. As a result, a total of 10 461 articles were retrieved, of which 8 681 were kept after de-duplication, and 41 RCTs were included after screening, with a generally higher risk of bias. The outcomes of included RCTs were classified into 9 categories, namely, clinical symptom outcomes, neuroimaging outcomes, neuroelectrophysiological outcomes, blood biochemical outcomes, hemorheology outcomes, physical signs, syndrome scores of traditional Chinese medicine(TCM), clinical effective rate, and safety outcomes. Among them, the most frequently reported outcomes of included RCTs were blood biochemical outcomes, and clinical symptom outcomes showed the highest reporting rate. Besides, 9 RCTs reported syndrome scores of TCM as the outcomes and illustrated corresponding evaluation criteria. The analysis showed that the application of RCT outcomes in this field had clinical rationality and limitations, and there were also some deficiencies in the trial design level, namely, no distinction between primary and secondary outcomes, insufficient blind methods, not detailed description of outcomes, disunity of evaluation tools, and despised endpoint outcomes. These limitations and deficiencies were negatively affecting the quality of RCTs of CHMF in the treatment of CSVD-VCI. Therefore, we suggest that future researchers should be well prepared in the top-level design stage, and actively construct the core outcome set of this field, so as to improve the quality of clinical trials.

Objective::Bioinformatic analysis was used to compare the gene expression profile between asthma patients and healthy people, and the gene characteristics of asthma were preliminarily identified and the potential mechanism and drugs were revealed. Method::The GSE74986 gene expression profile was downloaded from the gene expression omnibus (GEO) and the differentially expressed genes (DEGs) were analyzed by GEO2R. Then the gene heat map of DEGs was made by Morpheus, and their gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) analysis were performed by DAVID 6.8. Moreover, the protein-protein interaction (PPI) network and hub genes were constructed by String 10.5. Finally, the significant modules were analyzed by MCODE in Cytoscape 3.6.1, small molecule drugs related to asthma were screened through Coremine Medical. Result::A total of 510 DEGs were screened, including 29 up-regulated genes and 481 down-regulated genes. DEGs were mainly involved in these biological processes and pathways, including chromatin silencing, transcriptional regulation of RNA polymerase Ⅱ promoter, protein transport, messenger RNA (mRNA) processing, RNA splicing, ubiquitin-mediated proteolysis, protein processing in the endoplasmic reticulum, RNA transport, and myeloid differentiation factor (MyD)-dependent Toll-like receptor signaling pathway, platelet activation, nucleotide binding oligomerization domain (NOD)-like receptor signaling pathway and so on. A total of 9 hub genes were obtained, including T-complex protein 1 subunit theta (CCT8), T-complex protein 1 subunit alpha (TCP1), 26S protease regulatory subunit S10B (PSMC6), heat shock protein 90 alpha (HSP90A)A1, cell cycle protein C (CCNC), HSP90AB1, 26S proteasome non-ATPase regulatory subunit 6 (PSMD6), ubiquitin-specific protease 14 (USP14) and eukaryotic translation initiation factor 4E (EIF4E). Two important modules were obtained. The genes in two modules mainly involved these biological process, such as splice, ubiquitin-mediated proteolysis, protein modification, RNA modification and so on. Some potential molecular drugs for the treatment of asthma, such as anisomycin and genistein, have been developed. Conclusion::DEGs and hub genes can contribute to understanding the molecular mechanism of asthma and providing potential therapeutic targets and drugs for the diagnosis and treatment of asthma.
