This paper summarizes Professor SHI Zaixiang's clinical experience in treating high fever caused by sepsis using Chaihu Guizhi Ganjiang Decoction （柴胡桂枝干姜汤）. He holds that the key pathogenesis of sepsis involves constrained heat in the shaoyang and internal accumulation of water and fluids. The clinical manifestations such as high fever， chills， and alternating sensations of cold and heat are attributed to pathogenic heat constrained in the shaoyang. Meanwhile， soft tissue edema and serous cavity effusions are due to shaoyang dysfunction and internal water retention. In clinical practice， treating sepsis-related high fever requires addressing both the shaoyang-constrained heat and the associated edema and effusions. The therapeutic approach focuses on harmonizing the shaoyang and resolving internal fluids， using Chaihu Guizhi Ganjiang Decoction as the base formula with flexible modifications. Professor SHI emphasizes that this formula shows a rapid antipyretic effect， particularly in cases where multiple anti-infective treatments have failed.

Objective To investigate the impact of phase Ⅱ cardiac rehabilitation on the rehabilitation needs and physical activity status of patients after coronary heart disease intervention.Methods A total of 90 patients with coronary heart disease who underwent percutaneous coronary intervention(PCI)in the Coronary Heart Disease Center of the hospital from August 2023 to August 2024 were selected as the research subjects.They were subjected to a 12-week standardized phase Ⅱ cardiac rehabilitation training.General data survey forms,cardiac rehabilitation scales,and the International Physical Activity Questionnaire were used for scale surveys to understand the patients' needs before and after rehabilitation and their weekly physical activity en-ergy expenditure.The cardiopulmonary exercise test gold standard,which reflects exercise capacity through three indicators-maximum oxygen uptake(VO2 max),anaerobic threshold(AT),and metabolic equivalents(MET),were used to compare the physical activity status before and after cardiac rehabilitation.Results Compared with before the implementation,after the implementation of cardiac rehabilitation,the autonomy score in-creased(21.36±1.85 vs.16.73±3.28),the process anxiety(12.60±3.87 vs.14.27±2.12)and outcome anxiety scores(2.31±1.76 vs.4.56±3.56)decreased,the level of low-intensity physical activity decreased[(2 711.62±1 487.09)min/week vs.(3 845.97±2 083.71)min/week],the levels of moderate-intensity[(1 314.67±783.54)min/week vs.(686.22±126.79)min/week],high-intensity[(1 861.33±798.27)min/week vs.(112.00±40.77)min/week],and total physical activity increased[(5 887.62±2 843.54)min/week vs.(4 644.19±2 287.16)min/week].The levels of VO2 max[(28.11±14.28)mL·min-1·kg-1 vs.(23.82±12.34)mL·min-1·kg-1],AT[(16.06±5.41)mL·min-1·kg-1 vs.(13.53±4.56)mL·min-1·kg-1],and MET[(6.89±1.59)mL·min-1·kg-1 vs.(5.78±1.21)mL·min-1·kg-1]all in-creased,with statistically significant differences(P＜0.05).Conclusion Phase Ⅱ rehabilitation after PCI can effectively improve patients' physical activity levels.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period，9 035 strains of Gram-negative bacteria were collected from 51 hospitals，of which 7 895（87.4%）were Enterobacteriaceae and 1 140（12.6%）were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli（ n=4 510，49.9%）， Klebsiella pneumoniae（ n=2 340，25.9%）， Pseudomonas aeruginosa（ n=534，5.9%）， Acinetobacter baumannii complex（ n=405，4.5%）and Enterobacter cloacae（ n=327，3.6%）. The ESBLs-producing rates in Escherichia coli， Klebsiella pneumoniae and Proteus spp. were 47.1%（2 095/4 452），21.0%（427/2 033）and 41.1%（58/141），respectively. The prevalence of carbapenem-resistant Escherichia coli（CREC）and carbapenem-resistant Klebsiella pneumoniae（CRKP）were 1.3%（58/4 510）and 13.1%（307/2 340）；62.1%（36/58）and 9.8%（30/307）of CREC and CRKP were resistant to ceftazidime/avibactam combination，respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii（CRAB）complex was 59.5%（241/405），while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa（CRPA）was 18.4%（98/534）. There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions，with statistically significant differences in the prevalence of CRKP and CRPA（ χ2=20.489 and 20.252， P<0.001）. The prevalence of CREC，CRKP，CRPA，CRAB，ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals（ χ2=11.953，81.183，10.404，5.915，12.415 and 6.459， P<0.01 or <0.05），while the prevalence of CRPA was higher in economically developed regions（per capita GDP ≥ 92 059 Yuan）than that in economically less-developed regions（per capita GDP <92 059 Yuan）（ χ2=6.240， P=0.012）. Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend，and Escherichia coli is ranked in the top，while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different，and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-positive bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-positive bacteria from blood cultures in member hospitals of National Bloodstream Infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:A total of 3 163 strains of Gram-positive pathogens were collected from 51 member units，and the top five bacteria were Staphylococcus aureus（ n=1 147，36.3%），coagulase-negative Staphylococci（ n=928，29.3%）， Enterococcus faecalis（ n=369，11.7%）， Enterococcus faecium（ n=296，9.4%）and alpha-hemolyticus Streptococci（ n=192，6.1%）. The detection rates of methicillin-resistant Staphylococcus aureus（MRSA）and methicillin-resistant coagulase-negative Staphylococci（MRCNS）were 26.4%（303/1 147）and 66.7%（619/928），respectively. No glycopeptide and daptomycin-resistant Staphylococci were detected. The sensitivity rates of Staphylococcus aureus to cefpirome，rifampin，compound sulfamethoxazole，linezolid，minocycline and tigecycline were all >95.0%. Enterococcus faecium was more prevalent than Enterococcus faecalis. The resistance rates of Enterococcus faecium to vancomycin and teicoplanin were both 0.5%（2/369），and no vancomycin-resistant Enterococcus faecium was detected. The detection rate of MRSA in southern China was significantly lower than that in other regions（ χ2=14.578， P=0.002），while the detection rate of MRCNS in northern China was significantly higher than that in other regions（ χ2=15.195， P=0.002）. The detection rates of MRSA and MRCNS in provincial hospitals were higher than those in municipal hospitals（ χ2=13.519 and 12.136， P<0.001）. The detection rates of MRSA and MRCNS in economically more advanced regions（per capita GDP≥92 059 Yuan in 2022）were higher than those in economically less advanced regions（per capita GDP<92 059 Yuan）（ χ2=9.969 and 7.606， P=0.002和0.006）. Conclusions:Among the Gram-positive pathogens causing bloodstream infections in China， Staphylococci is the most common while the MRSA incidence decreases continuously with time；the detection rate of Enterococcus faecium exceeds that of Enterococcus faecalis. The overall prevalence of vancomycin-resistant Enterococci is still at a low level. The composition ratio of Gram-positive pathogens and resistant profiles varies slightly across regions of China，with the prevalence of MRSA and MRCNS being more pronounced in provincial hospitals and areas with a per capita GDP≥92 059 yuan.

Objective:To analyze and summarize the clinical characteristics of mpox patients, thereby to rise clinicians′ awareness of severe mpox and provide a foundation for clinical diagnosis and treatment.Methods:The clinical data were retrospectively analyzed in 41 mpox patients treated at the Beijing You′an Hospital, Capital Medical University, from June to November 2023. Patients were categorized into mild and severe cases based on clinical manifestations, and laboratory results of the two groups were compared. Statistical analysis was performed using the Mann-Whitney U test. Results:The clinical manifestations of 41 mpox patients mainly included fever, rash and lymphadenopathy. Five patients with severe mpox might develop serious complications, including bacterial pneumonia, type Ⅰ respiratory failure, fungal infections, penile or perianal dry gangrene, penile soft tissue edema, intestinal obstruction, septic shock, perianal abscess, and necrotizing fasciitis. Patients with severe mpox had significantly higher white blood cell count (WBC), neutrophil count and C-reactive protein (CRP) level compare to those with mild cases (14.60(9.92, 24.08)×10 9/L vs 6.41(5.64, 8.37)×10 9/L, 12.43(7.02, 21.15)×10 9/L vs 3.35(2.46, 5.03)×10 9/L, 108.20(56.20, 124.10) mg/L vs 16.6(6.25, 49.98) mg/L), while the albumin level and CD4 + T lymphocyte count in the severe group were significantly lower compared to the mild cases (31.80(22.90, 35.15) g/L vs 44.70(42.90, 47.40) g/L, 24.00(12.00, 81.50)/μL vs 606.00(414.50, 767.50)/μL)). All these differences were statistically significant ( U=2.81, 3.02, 2.98, 3.56 and 3.26, respectively, all P<0.01). Conclusions:In clinical practice, clinicians should be vigilant for the possibility of severe mpox if patients exhibit a significant increase of WBC and CRP, a significant decrease in CD4 + T lymphocyte count, or if they develop severe complications.

This study aims to investigate the synergistic antimicrobial effect of demethylzeylasteral meropenem against NDM-1-positive Escherichia coli.Firstly,the nitrocefin hydrolysis assay and molecular docking assay were used to determine the inhibitory effect and mechanism of demethyl-zeylasteral on the hydrolytic activity of the NDM-1 protein.Secondly,the synergistic bacteriostatic effect of demethylzeylasteral with the carbapenem antibiotic meropenem was confirmed by the checkerboard minimum inhibitory concentration assay,growth curve assay,and inhibition zone as-say.The synergistic bactericidal effect of the combination was further determined by the time-kill-ing assay,live/dead bacterial staining assay,and membrane integrity assay.Finally,the G.mellonel-la infection model demonstrated the protective effect of demethylzeylasteral and meropenem.The results indicated that demethylzeylasteral significantly inhibited the hydrolytic activity of NDM-1(IC50=0.32 mg/L)and competitively affected the binding of NDM-1 to meropenem.In vitro tests showed that demethylzeylasteral had good a synergistic antibacterial effect with meropenem and could exert a synergistic bactericidal effect by enhancing the membrane damage of bacteria caused by meropenem.In vivo assays demonstrated that demethylzeylasteral increased the protective effect of meropenem from 67％to 80％.The results obtained in this study provide a therapeutic strategy and antibacterial synergist for treating NDM-1-positive bacterial infections.

Objective To investigate the effects of glucagon-like peptide-1 receptor agonists(GLP-1 RAs)on lipotoxic oxida-tive stress in islet cells,and to explore whether the mechanism is related to the regulation of LINC01180/miR-30b/CPT1A pathway.Methods Gene chips and bioinformatics analysis predicted that LINC01180might regulate microRNA and related proteins.In vivo and in vitro modeling,the models were divided into control group,high-fat group and GLP-1 RAs group.The content of malondialdehyde(MDA)and the activity of total antioxidant capacity(T-AOC)were detected.Hematoxylin-eosin staining and immunohistochemical Reg3γ analysis were determined either.Real-time quantitative polymerase chain reaction(RT-qPCR)was used to detect the expres-sion levels of LINC01180,miR-30b and CPT1A.The protein expression levels of CPT1A was detected by Western blot.LINC01180 was inhibited and overexpressed by transient transfection,the expression levels of miR-30b and CPT1A after transfection were detected by RT-qPCR.Results Bioinformatics analysis showed that LINC01180/miR-30b/CPTIA formed ceRNA regulatory network.The lipo-toxic oxidative stress was significantly improved in GLP-1RAs model,and the expression levels of LINC01180 was decreased,while the expression levels of miR-30b and CPT1A were increased.Transfection of LINC01180significantly affected the expression levels of miR-30b and CPT1 A.Conclusion GLP-1RAs ameliorates lipotoxic oxidative stress by down-regulating the expression levels of LINC01180 and up-regulating the expression of miR-30b and CPT1A.

Objective:To survey the post competency of general practitioners who completed residency training in Suzhou Municipal Hospital.Methods:A questionnaire survey on post competency of general practitioners was conducted from January to March 2022. General practitioners who completed standardized residential training in Suzhou Municipal Hospital from 2009 to 2021 were randomly selected for the survey. The self-designed questionnaire included the basic information and post competency in terms of clinical, public health, research and teaching abilities as well as medical ethics and humanism. A self-evaluation was also performed and the abilities were graded (A 86-100, B 70-85, C 55-69, D 0-54), and grade A was classified as excellent.Results:A total of 163 questionnaires were distributed and 157 valid ones were collected with a recovery rate of 96.3%. Among 157 respondents 62 (39.5%) were males. The participants mainly worked in urban community health service institutions (78 (49.7%)), and most of them worked as general practice (119 (75.8%)). For the self-assessment of clinical skills, the proportion of respondents with excellent abilities in history taking, basic drug use, diagnosis and treatment of common diseases, and chronic disease management was 58.8% (70/119), 57.1% (68/119), 54.6% (65/119) and 54.6% (65/119), respectively. The proportion of respondents with excellent abilities in evidence-based clinical decision making, physical examination, tests interpretation, referral services, family medical services, rehabilitation services, first aid, and psychological counseling and treatment was 43.7% (70/119), 42.9% (52/119), 38.7% (46/119), 37.8% (45/119), 33.6% (40/119), 22.7% (27/119), 21.0% (25/119), and 16.8% (20/119), respectively. For the self-assessment of basic public health service ability, the proportion of respondents with excellent abilities in health education, disease prevention and control, health management, health care for key and special groups, handling public health emergencies, management of infectious diseases, epidemiology-based community diagnosis and community health leadership was 38.7% (46/119), 33.6% (40/119), 33.6% (40/119), 26.1% (31/119), 25.2% (30/119), 2.7% (27/119), 22.7% (27/119), and 21.0% (25/119), respectively. For humanistic literacy, the proportion of respondents with excellent abilities in privacy protection, sense of responsibility for patients, understanding patients′ needs, effective communication and cooperation with patients was 82.4% (98/119), 73.9% (88/119), 61.3% (73/119), 55.5% (66/119) and 2.1% (62/119), respectively. For research and teaching, the proportion of respondents with excellence abilities in continuous learning and innovation, training and teaching and literature retrieval was 47.9% (57/119), 10.9% (13/119), 10.1% (12/119), respectively. In addition 56.3% (67/119) of respondents were interested in scientific research, 23.5% (28/119) had published articles as the first author or correspondence author, and only 6.7% (8/119) had scientific research projects in the last 5 years.Conclusion:The post competency of general practitioners who received standardized residency training in our hospital varies in different aspects, their abilities in basic public health service, scientific research and teaching are relatively low, which need to be strengthened.

From February 1 to April 30, 2021, 48 general practice resident physicians in the First Affiliated Hospital of Naval Medical University were randomly divided into study group and control group with 24 in each group. The common comorbidities of the community-dwelling elderly, namely diabetes, diabetic retinopathy and osteoporosis were selected as teaching cases. The residents in control group received conventional teaching, while the scenario simulation teaching model of multicomorbity co-treatment was applied for the study group. The teaching effect, satisfaction and self-efficacy scores were compared between two groups. After training, the knowledge levels, the mastery of referral indicators and the performance of fundus ophthalmoscopy in the study group were significantly better than those in the control group ( t=2.27, 6.34, 4.09; P<0.05). They were (80.96±11.27) vs. (73.96±10.09), (10.33±2.41) vs. (6.38±1.88), (70.27±10.44) vs. (63.50±7.98), and students′ satisfaction and self-efficacy evaluation were higher than those of the observation group (all P<0.05). It is suggested that the simulation teaching of multi-disease co-treatment scenario is more beneficial than the traditional teaching to improve the comprehensive care ability of standardized training physicians in general practice for patients with chronic disease.
