ObjectiveTo explore the current situation and influencing factors of humanistic care experience among patients visiting traditional Chinese medicine （TCM） outpatient clinics in China， and to provide a basis for optimizing TCM-characterized services in both TCM and Western medicine hospitals. MethodsA multi-center cross-sectional study was conducted using convenience sampling to select 35 hospitals across 13 provinces in China （including 3 TCM hospitals and 32 TCM outpatient clinics in general hospitals）. A total of 3，430 patients were surveyed using the general information questionnaire and the Outpatient Humanistic Care Experience Questionnaire， with data collected via Questionnaire Star. Univariate analysis and multiple linear regression were employed to examine the impacts of patient characteristics， visit characteristics， hospital type （TCM hospital/general hospital）， and geographic region （eastern/central/western） on humanistic care experience. ResultsThe total score of humanistic care experience was 194 （188， 233）. Univariate analysis showed that gender， educational level， current residence， per capita monthly household income， location attribute of medical institutions， number of previous visits to this hospital， payment method of medical expenses， previous hospitalization history in this hospital， frequency of outpatient visits within the past 12 months， self-rated disease severity， familiarity with the outpatient procedures， implementation of the follow-up service provided by the hospital， satisfaction with follow-up services， the grade of the hospital visited， geographical region of the hospital visited， and the department visited had an impact on the humanistic care experience during outpatient visits （P<0.05）. Multivariate analysis demonstrated that educational level （β=0.609， P=0.011）， self-rated disease severity （β=-0.646， P=0.047）， familiarity with outpatient procedures （β=4.784， P<0.001）， satisfaction with follow-up services （β=6.365， P<0.001）， and the grade of the hospital visited （β=-5.487， P<0.001） affected the humanistic care experience in outpatient medical treatment， explaining 24.4% of the total variation. ConclusionHumanistic care experience in TCM outpatient clinics is influenced by multiple factors. It is recommended to optimize the medical treatment process， strengthen doctor-patient communication training， and establish a precise follow-up mechanism， with a focus on improving care perceptions among patients with lower education levels and those attending primary-level hospitals， to refine the TCM-characterized service system.

ObjectiveTo demonstrate the long-term effect of Yishi Therapy for primary tinnitus and analyze the factors affecting the effectiveness. MethodsWe conducted long-term follow-ups of primary tinnitus cases treated with Yishi Therapy during 1 January 2017 to 30 June 2023 by face-to-face， online and telephone between 1 July 2023 and 31 January 2024， to understand the final regression of primary tinnitus and lifestyle changes. We retrospectively analysed the basic data of patients before treatment， and statistically analysed the recovery rate and overall effective rate of tinnitus treated by the Yishi Therapy， and the factors affecting the effectiveness such as lifestyle， age， duration of disease， gender， tinnitus location， severity of tinnitus， accompanying symptoms and complications on the overall effective rate. ResultsA total of 496 cases of primary tinnitus completed follow-ups successfully， and the total Tinnitus Evaluation Questionnaire （TEQ） at follow-up was significantly lower than that before treatment （P＜0.001）. Among the 496 cases， 101 （20.36%） cases cured， 189 （38.10%） cases showed significant improvement， 116 （23.39%） cases were effective， 90 （18.15%） cases were ineffective， and the overall effect rate was 81.85% （406/496）. At follow-up， the score of lifestyle was higher than that before treatment （P＜0.001）. Grouped by the score of lifestyle at follow-up， the effective rates of better lifestyle group and poor lifestyle group were 97.53% （237/243） and 66.80% （169/253）， respectively， with statistical significance （P＜0.001）. Grouped by the mean value of the difference in lifestyle scores before and after treatment， the effective rates of the group with greater lifestyle adjustment and the group with smaller adjustment were 97.55% （239/245） and 66.53% （167/251）， respectively， and the differences were statistically significant （P＜0.001）. Binary logistic regression showed that the better lifestyle， the greater lifestyle adjustment and the severity of tinnitus were positively correlated with the total effective rate of tinnitus （P＜0.001）， while older and hearing loss were negatively correlated with the total effective rate of tinnitus （P＜0.05）. ConclusionYishi Therapy on primary tinnitus shows good long-term effect， lifestyle， severity of tinnitus， hearing loss or not， age are the relevant factors affecting the efficacy of tinnitus， lifestyle is the main factor affecting clinical efficacy.

Objective:To explore the expression and clinical significance of heme oxygenase-1 (HO-1) and quinone oxidoreductase (NQO-1) in children with different severity levels of mycoplasma pneumoniae (MP) infection.Methods:A total of 140 children with MP infection who were treated at the Affiliated Hospital of Jining Medical University from January to June 2022 were selected as the observation group, while 100 healthy children who underwent physical examination were selected as the control group. The serum levels of interleukin-2 (IL-2), IL-6, IL-10, IL-1β, tumor necrosis factor α (TNF-α), interferon γ (IFN-γ), HO-1, and relative expression of NQO-1 protein were compared between the control group and the observation group, as well as between children with different degrees of MP infection, Forced vital capacity (FVC), maximum expiratory volume in the first second (FEV 1), peak expiratory flow rate (PEF), 50% forced expiratory flow rate and maximum mid expiratory flow rate (MEF 25-70), 50% forced expiratory flow rate (MEF 50), and 25% forced expiratory flow rate (MEF 25). Pearson correlation method was used to analyze the correlation between the expression of HO-1 and NQO-1 with inflammatory factors and lung function indicators. The receiver operating characteristic (ROC) curve was used to analyze the value of HO-1 and NQO-1 expression in predicting severe MP. Results:The serum levels of IL-2, IL-6, IL-10, IL-1β, TNF-α, IFN-γ, and HO-1 in the observation group were significantly higher than those in the control group (all P<0.05), while the relative expression level of NQO-1 protein was significantly lower than that in the control group ( P<0.05). The FVC, FEV 1, PEF, MEF 25-70, MEF 50, and MEF 25 in the observation group were significantly lower than those in the control group (all P<0.05). The serum levels of IL-2, IL-6, IL-10, IL-1β, TNF-α, IFN-γ, and HO-1 in the observation group of severe children were significantly higher than those in mild children (all P<0.05), while the relative expression of NQO-1 protein, FVC, FEV 1, PEF, MEF 25-70, MEF 50, and MEF 25 were significantly lower than those in mild children (all P<0.05). HO-1 in children with MP infection is positively correlated with IL-6, IL-1β, and IFN-γ, while the relative expression level of NQO-1 protein is negatively correlated with IL-6, IL-1β, and IFN-γ (all P<0.05); HO-1 was negatively correlated with MEF 50 and MEF 25, while the relative expression level of NQO-1 protein was positively correlated with MEF 50 (all P<0.05). The area under the ROC curve for predicting the relative expression levels of HO-1 and NQO-1 proteins in severe MP was 0.871 and 0.934, respectively (all P<0.05). Conclusions:The expression of serum HO-1 and NQO-1 in children with MP infection is correlated with cytokines and lung function indicators, and has certain application value in predicting severe illness.

Objective To understand the current status and influencing factors of patient perception for humanistic care in China hospitals,and to provide a basis for developing nursing humanistic care measures and improving the quality of nursing humanistic care services.Methods A total of 30,099 outpatients and inpatients from 107 hospitals in 30 provinces(autonomous regions and municipalities)from July to August 2022 as survey subjects.A general information questionnaire and the Relational Caring Questionnaire-Patient Form were used for a cross-sectional survey,and a single-factor analysis was used to analyze the influencing factors of patient relationship care.Results Finally,29 108 valid questionnaires were collected,and the effective questionnaire recovery rate was 96.7％.The patient evaluation of relationship care was(65.72±8.61)points.Single-factor analysis showed that gender,age,marital status,children's situation,education level,occupation,place of residence,average family income,medical insurance type,visiting department,and location of the visiting hospital,and whether or not surgery were influencing factors of patient relationship care(P＜0.05).Conclusion The evaluation score of caregiver-patient relationship care among Chinese hospital patients is above average,but there is still room for improvement in western and rural regions,seriously ill and outpatient patients,low-income and low-medical insurance reimbursement populations,and non-surgical patients.Medical institutions at all levels should optimize and improve nursing humanistic care services based on influencing factors,and further enhance patients'perception of nursing humanistic care.

Objective To investigate the changes of OAT expression in bone cells in chronic renal failure(CRF)and involved mechanism,and to explore the effect of OAT expression on bone metabolism.Methods Ra-ndomly divide the rats into a control group(n=6)and a model group(n=6).The model group established a rat chronic renal failure model using"single nephrectomy+adenine gavage"method,and the red blood cell(RBC)and hemoglobin(HGB)of the rat body were measured using a blood routine analyzer;Measure indicators such as creatinine(Cr),urea nitrogen(BUN),uric acid(UA),blood calcium(Ca2+),and blood phosphorus(P3+)using a fully automated biochemical analyzer;Pathological examination of rat kidneys;X-ray examination of rat tibia;Immunohistochemical examination of bone tissue OAT1 level.Results The bone density of the model group rats is lower than that of the control group;The calcium and phosphorus metabolism of rats in the model group was in metabolic disorder,and the OAT1 value of bone tissue binding was much lower than that of the control group(P= 0.0018),which was statistically significant.(P=0.0018)Conclusion Chronic renal failure affected the binding ability of OAT1 in bone tissue,leading to the metabolic disorder for calcium absorption and phosphorus metabolism,thus aggravating renal osteodystrophy(P<0.05).

Objective:To establish a Plaque-reduction Neutralization Test (PRNT) for the detection of neutralizing antibody titers of Human Respiratory Syncytial Virus (HRSV) and optimize the conditions for preliminary application.Methods:The CHO expression system was used to produce palivizumab monoclonal antibody (palivizumab) and the influencing factors such as cell type, cell culture duration, fixation and permeabilization protocols, and blocking agents. The reproducibility of the method was verified and its correlation was verified with conventional PRNT. Finally, the optimized PRNT assay was further used to determine neutralizing antibody titers against HRSV subtypes A and B in BALB/c mouse serum (immunized by intramuscular injection of HRSV fusion proteins).Results:Palivizumab was expressed at approximately 50 mg/L. The optimal working conditions for PRNT were as follows: culturing HEp-2 cells for 2 days, fixing with 4% (V/V) paraformaldehyde at room temperature for 15 min followed by 0.2% (V/V) Triton X-100 permeabilization for 15 minutes as the optimal fixation-permeabilization and removing the blocking step. The overall coefficient of variation (CV) for the reproducibility validation of this method was <15%, showing a good linear relationship with the conventional PRNT. The Spearman correlation coefficient r s was 0.983. This method was used to detect neutralizing antibody titers in mouse sera against HRSV subtype A strain long and subtype B strain 9320, and the fusion proteins combined with AlOH and CpG adjuvant induced the highest neutralizing antibody titers in mice. Conclusion:The HRSV neutralizing antibody assay established in this study is rapid, reproducible, high-throughput, and can be used to detect neutralizing antibodies to HRSV subtypes A and B.

Objective The objective of this study was to investigate the effects of propofol on glycolysis of lung cancer,and to further explore its potential mechanism of inhibiting glycolysis in lung cancer through glucose transporter 4(GLUT4).Methods Human lung cancer A549 cells and mouse lung cancer LLC cells were cultured,and the experimental groups were set as the blank control group(Control group)and propofol(10μmol/L)group(Propofol group).The CCK-8 assay was used to detect cell viability;Immunofluorescence(IF)was used to detect the expression of Ki-67 in lung cancer cells and A549 cell xenografts.Extracellular acidi-fication rate(ECAR)and mitochondrial oxygen consumption(OCR)assays were used to detect the cellular metabolic levels;ELISA was used to detect the cell lactate and pyruvate content;Molecular docking experiments were used to detect the binding ability of GLUT4 with propofol using CB-Dock online tool;The glucose uptake kit was used to detect glucose uptake;Western blot was used to detect the expression of GLUT4,HK2,and PFK1 proteins in lung cancer cells.Results The cell viability of A549 cells(0.661±0.052)and LLC cells(0.632±0.033)in the propofol group was significantly inhibited by 10 μmol/L of propofol in lung cancer cells(P＜0.001).Compared with the control group,the average fluorescence intensity of Ki-67 in A549 and LLC positive cells(0.663±0.064 and 0.540±0.070)was significantly suppressed(P＜0.001).The ELISA results showed that compared with the control group,the levels of lactate and pyruvate in the propofol group decreased(P＜0.001),and under the action of propofol,the glucose uptake ability of cells decreased(P＜0.001).Molecular docking experiments using the CB-Dock online tool showed that GLUT4 had the strongest binding force with propofol.The results of Western blot showed a decrease in the expression of GLUT4 and its downstream HK2 and PFK1 pro-teins.After transient transfection and knockdown of GLUT4,cellular lactate(P＜0.001)and pyruvate content(P＜0.01)decreased,glu-cose uptake capacity reduced,and the inhibitory effect of propofol on glycolysis disappeared.In A549 cell xenografts,the weight of xenografts in the propofol group was significantly smaller than that of the model group(P＜0.001).Compared with the model group,the lactate content and pyruvate content decreased in the propofol group(P＜0.001).Conclusion Propofol can inhibit the proliferation of lung cancer cells and the progression of A549 cell xenografts in bearing mice by inhibiting the glycolysis of lung cancer cells,and its mechanism may be related to the targeted effect of GLUT4 on the glycolysis of lung cancer cells.

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.
