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.

Objective CT scans combined with Mimics software were used to measure femoral offset(FO),rotation center height(RCH)and lower leg length discrepancy(LLD)following total hip arthroplasty(THA),and the relationship between FO,RCH and LLD after THA is discussed.Methods Retrospective analysis was performed on 40 patients with unilateral THA who met standard cases from October 2020 to June 2022.There were 21 males and 19 females,18 patients on the left side and 22 patients on the right side,aged range from 30 to 81 years old,with an average age of(58.90±14.13)years old,BMI ranged from 17.3 to 31.5 kg·m-2withan average of(25.3±3.4)kg·m-2.There were 30 cases of femoral head necrosis(Ficattype Ⅳ),2 cases of hip osteoarthritis(Tonnis type Ⅲ),2 cases of developmental hip dislocation combined with end-stage osteoarthritis(Crowe type Ⅲ),and 6 cases of femoral neck fracture(Garden type Ⅳ).Three-dimensional CT reconstruction of pelvis was taken preoperative and postoperative,and three-dimensional reconstruction model was established after processing by Mimics software.FO,RCH and LLD were measured on the model.The criteria for FO reconstruction were as follows:postoperative bi-lateral FO difference less than 5 mm;the standard for equal length of both lower limbs was as follows:postoperative LLD differ-ence less than 5 mm.Results Bilateral FO difference was positively correlated with LLD(r=0.744,P＜0.00l).Chi-square test was performed between the FO reconstructed group and the non-reconstructed eccentricity group:The results showed that the i-sometric ratio of lower limbs in the FO reconstructed group was significantly higher than that in the FO reconstructed group(x2=6.320,P=0.012).The bilateral RCH difference was significantly negatively correlated with LLD(r=-0.877,P＜0.001).There is a linear relationship between bilateral FO difference and bilateral RCH difference and postoperative LLD,and the lin-ear regression equation is satisfied:postoperative LLD=0.038x-0.099y+0.257(x:postoperative bilateral FO difference,y:post-operative bilateral RCH difference;Unit:cm),F=77.993,R2=0.808,P=0.009.Conclusion After THA,LLD increased with the increase of FO and decreased with the increase of RCH.The effect of lower limb isometric length can be obtained more easily by reconstruction of FO.There is a linear relationship between the bilateral FO difference and the bilateral RCH difference after THA and LLD,and the regression equation can provide a theoretical reference forjudging LLD.

Objective To explore the value of artificial intelligence federated learning system based on chest X-ray films for pathogen diagnosis of community-acquired pneumonia(CAP)in children.Methods Totally 900 cases of CAP children from 2 hospitals were retrospectively enrolled,including bacterial,viral and mycoplasma CAP(each n=300),and chest posteroanterior X-ray films were collected.Meanwhile,chest posteroanterior X-ray films of 5856 children from the publicly available dataset GWCMCx were collected,including 4273 CAP images and 1583 healthy chest images.All above 6756 images were divided into training set(n=5359)and validation set(n=1397)at the ratio of 8∶2.Then a pathogen diagnosis model of children CAP was established based on attention mechanism.Binary and ternary diagnostic algorithms were designed,and federated deployment training was performed.The efficacy of this system for pathogen diagnosis of children CAP was analyzed and compared with DenseNet model.Results Based on all data,the accuracy of the obtained artificial intelligence federated learning system model for diagnosing children CAP was 97.00%,with the area under the curve(AUC)of 0.990.Based on hospital data,the AUC of this system using single imaging data and clinical-imaging data for pathogen diagnosis of children CAP was 0.858 and 0.836,respectively,both better than that of DenseNet model(0.740,both P＜0.05).Conclusion The artificial intelligence federated learning system based on chest X-ray films could be used for pathogen diagnosis of children CAP.

Objective:To investigate the effects and molecular mechanism of non-coding RNA-activated DNA damage(NORAD)induced autophagy on oxaliplatin resistance in adenocarcinoma of esophagogastric junction (AEG).Methods:Four pairs of surgical samples of AEG and para-carcinoma normal tissues from patients with advance AEG treated in Anyang Tumor Hospital from January to June 2023 were collected. The expression of NORAD in AEG and para-carcinoma tissues was analyzed by long non-coding RNA microarray chip. The primary tumor cell line of AEG (PDC) was derived from fresh AEG tissues. Oxaliplatin-resistant cell lines of PDC and AEG cell line OE19 (PDC-R and OE19-R) were established. NORAD expression knockdown PDC-R and OE19 cell lines (shNORAD PDC-R and shNORAD OE19-R) were prepared by transfection. The target of NORAD, the correlation and interaction between microRNA-433-3p (miR-433-3p) and NORAD were predicted using Starbase v3.0 and DIANA-lncBase v3.0. PDC, PDC-R, OE19 and OE19-R cells were co-transfected with miR-144-3p and wild-type NORAD (NORAD-WT) or mutant NORAD (NORAD-Mut) plasmid, respectively. Dual-luciferase reporter assay was used to verify the correlation between NORAD and miR-433-3p. The expression levels of NORAD and miR-433-3p in normal gastric mucosal cell line GES-1 and AEG cell lines PDC, PDC-R, shNORAD PDC-R, OE19, OE19-R and shNORAD OE19-R were detected by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). The expression of p62 protein and microtubule-associated protein 1 light chain 3B-Ⅱ (LC3B-Ⅱ) was determined by Western blotting. The half inhibitory concentration (IC 50) of PDC, PDC-R, shNORAD PDC-R, OE19, OE19-R and shNORAD OE19-R cells was measured by cell counting kit-8 (CCK-8) assay. Independent sample t-test was used for statistical analysis. Results:The results of microarray analysis showed that NORAD was significantly up-regulated in AEG compared with that in para-carcinoma tissues (fold change≥2.0, P<0.05). Bioinformatics studies found that miR-433-3p was the potential target of NORAD. The results of dual-luciferase reporter assay indicated that the relative luciferase activity of the NORAD-WT group was lower than that of NORAD-Mut group in PDC and PDC-R cells (0.441±0.104 vs. 0.928±0.204, 0.449±0.112 vs. 0.947±0.201), and the differences were statistically significant ( t=-14.74 and -14.94, both P<0.001). The results of dual-luciferase reporter assay of OE19 and OE19-R cell lines were the same as those of PDC cell lines. The results of qRT-PCR showed that the expression of NORAD in GES-1 cells (1.016±0.213) was lower than that of PDC cells (2.194±0.322) and PDC-R cells (4.040±0.336), and the differences were statistically significant ( t=-14.94 and -37.21, both P<0.001). Furthermore, the expression level of NORAD in PDC was also found to be lower than that in PDC-R cells, and the difference was statistically significant ( t=-19.43, P<0.001). Additionally, shNORAD PDC-R cells exhibited lower expression level of NORAD (0.290±0.165) compared with PDC-R cells, and the difference was statistically significant ( t=-49.05, P<0.001). The expression level of miR-433-3p in GES-1 cells (1.017±0.248) was higher than that in PDC cells (0.470±0.156) and PDC-R cells (0.203±0.045), and the differences were statistically significant ( t=9.15 and 15.85, both P<0.001). Moreover, the expression level of miR-433-3p was found to be higher in PDC cells compared with PDC-R cells, and the difference was statistically significant ( t=8.11, P<0.001). Additionally, the expression level of miR-433-3p in shNORAD PDC-R cells (0.699±0.256) was also higher than that in PDC-R cells ( t=9.37, P<0.001). The results of Western blotting showed that the expression of LC3B-Ⅱ in PDC-R was higher than that in PDC cells (0.426±0.060 vs. 0.212±0.041), the expression of LC3B-Ⅱ in shNORAD PDC-R cells (0.155±0.029) was lower than that in PDC cells, and the differences were statistically significant ( t=8.70 and -79.45, both P<0.001). However the expression of p62 protein in each cell line showed an opposite trend, with a lower relative expression in PDC-R than PDC (0.205±0.031 vs. 0.311±0.400), and the expression in shNORAD PDC-R (0.504±0.084) was higher than that in PDC, and the differences were statistically significant ( t=-31.19 and 62.80, both P<0.001). The expression patterns of NORAD, miR-433-3p, LC3B-Ⅱ and p62 proteins in OE19, OE19-R and shNORAD OE19-R cells were similar to those in PDC. The results of CCK-8 assessment of target cell viability showed that the IC 50 values of PDC, PDC-R and shNORAD PDC-R cell lines were 14.28, 22.27 and 2.51 μg/mL, respectively; and the IC 50 values of OE19, OE19-R and shNORAD PDC-R cell lines were 3.95, 8.12 and 1.89 μg/mL, respectively. Conclusions:NORAD is highly expressed in AEG tissues and cells. NORAD is overexpressed in oxaliplatin-resistant cell lines and increase the autophagy activity of cells. After NORAD is knockdown, autophagy activity is inhibited and the sensitivity of AEG cells to oxaliplatin is significantly enhanced.

BACKGROUND:High tibial osteotomy results in massive blood loss during the perioperative period.Tranexamic acid can effectively reduce perioperative blood loss.However,the method of tranexamic acid application has not been unified. OBJECTIVE:To investigate the effect and safety of different methods of tranexamic acid on perioperative blood loss in the high tibial osteotomy. METHODS:A total of 160 patients who underwent primary unilateral high tibial osteotomy in the Binzhou Medical University Hospital from January 2019 to December 2021,including 69 males and 91 females,were randomly divided into four groups(n=40 per group).Among them,40 patients were given an intravenous infusion of saline containing 2 g tranexamic acid 10 minutes before tourniquet release(venous group);40 patients were given an intravenous infusion of 1 g tranexamic acid and 1 g tranexamic acid was injected through a drainage tube after the closure of the incision(combined group);40 patients were given 2 g tranexamic acid infusion into drainage tube after the closure of the incision(perfusion group);an additional 40 patients were given an intravenous infusion of the same amount of normal saline(blank group).The general information was compared among the four groups of patients.The hemoglobin,hematocrit,intraoperative blood loss,drainage volume,blood transfusion rate,incision complication,and the incidence of deep vein thrombosis were recorded on days 1,3 and 5 after operation in the four groups.The total blood loss and hidden blood loss were calculated. RESULTS AND CONCLUSION:(1)There was no statistically significant difference in general information among the four groups.(2)No significant difference was found in intraoperative blood loss among the four groups.(3)The maximum decreased values of hemoglobin and hematocrit on days 1,3 and 5 after operation,drainage volume,total blood loss and hidden blood loss were all ranked as the combined group

Objective:To investigate the correlation between triglyceride-glucose (TyG) index on admission and unfavorable outcomes of patients with moderate-to-severe traumatic brain injury (msTBI) at 6 months postinjury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 277 patients with msTBI admitted to Affiliated Jiangyin Hospital of Nantong University from January 2019 to December 2022, including 208 males and 69 females, aged 18-88 years [(57.0±15.1)years]. Glasgow Coma Scale (GCS) scores on admission were 3-8 points in 168 patients and 9-12 points in 109. According to the Glasgow Outcome Scale-Extended (GOSE) assessment at 6 months after injury, there were 121 patients with unfavorable outcomes (GOSE≤4 points) and 156 with favorable outcomes (GOSE≥5 points). The following indicators of the patients were recorded, including gender, age, history of diabetes, cause of injury, admission GCS, GCS motor score (GCSM), pupillary light reflex, worst Marshall CT classification within the first 24 hours after admission, admission TyG index, Mean Amplitude of Glycemic Excursions (MAGE) within 24 hours after admission, GCSM decline≥2 points within 72 hours after admission, craniotomy or not after admission, and prognosis, etc. TyG index served as the exposure variable focused in this study, which was calculated with fasting triglycerides and fasting blood glucose within 24 hours after admission. The 6-month prognosis of the patients was designated as the outcome variable of the study. After the patients were divided into different groups according to the three quantiles of the TyG index and unfavorable or favorable outcomes, the univariate analysis was conducted on watch variables, and variables with statistically significant differences were included in directed acyclic graphs (DAGs) for further identification of confounding variables. Factors which were found with no statistical significance in the univariate analysis but might affect insulin resistance after injury according to the authors′ previous researches were also included in the DAGs analysis. Three Logistic regression models were designed (Model 1 without correction, Model 2 with core variables of International Mission for Prognosis and Analysis of Clinical Trials in Traumatic Brain Injury (IMPACT) corrected, and Model 3 with confounding variables screened by DAGs corrected) to analyze whether the TyG index was an independent risk factor for the prognosis of msTBI patients. The optimal Logistic regression model was selected and then restricted cubic spline (RCS) was employed to investigate the relationship between the TyG index and the unfavorable outcomes.Results:The univariate analysis suggested that there were significant differences in gender, history of diabetes, MAGE, GCSM decline, and prognosis among the three quantiles of the TyG index ( P<0.05 or 0.01). Significant differences in age, history of diabetes, GCSM, pupillary light reflex, Marshall CT classification, TyG index, MAGE and GCSM decline were observed between unfavorable and favorable outcome groups ( P<0.05 or 0.01). The results of Logistic regression analysis that identified the confounding variables that influenced the correlation between the TyG index and unfavorable prognosis with DAGs suggested that a high TyG index level was significantly correlated with unfavorable outcomes in msTBI patients. Moreover, Model 3 that was corrected with confounding variables screened by DAGs had an optimal goodness-of-fit and adaptability. Model 3-based further RCS analysis indicated that the risk of unfavorable outcomes following msTBI may increase approximately linearly with the increase in TyG index within a certain range (TyG index<9.79). Conclusions:A high TyG index level on admission is the identified as an independent risk factor for unfavorable outcomes of patients with msTBI at 6 months postinjury. As the TyG index level increases, the risk of unfavorable outcomes also rises and may show a linear increasing trend within a certain range (TyG index<9.79).

ObjectiveTo observe the clinical efficacy and safety of Shugan Bushen Yulin Decoction （疏肝补肾毓麟汤， SBYD） in the treatment of asthenospermia and infertility with liver constraint and kidney deficiency. MethodsA multicenter， randomized， controlled clinical study was conducted in three hospitals in central China. Totally 95 patients with asthenospermia and infertility were controlled. According to random number table， the patients were divided into treatment group （47 cases） and control group （48 cases）. The control group was given vitamin E soft capsules （100 mg per time， twice daily） orally， and the treatment group was given SBYD （one dose daily， 30 min after breakfast and dinner， about 200 ml each time） orally. The course of treatment was 12 weeks in both groups. After the treatment， the sperm concentration， percentage of forward motile sperm （PR）， and percentage of total sperm activity， that is PR + percentage of non-progressively motile sperm （NP） were compared between groups， and the clinical efficacy was judged. Traditional Chinese medicine （TCM） syndrome score （inlcuding 6 single symptom scores and total symptoms score） and 21-item depression， anxiety， and stress scale （DASS-21） scores （including depression， anxiety and stress scores） were compared between the two groups before and after treatment. The patients were followed up for 6 months， and the pregnancy status of spouse between groups was compared. The occurrence of adverse events and vital signs during the trial were recorded for safety assessment. ResultsTwo cases in the treatment group and three cases in the control group dropped out. Finally， 45 cases in each group were included in the statistical analysis. The total effective rate was 86.67% （39/45） in the treatment group， significantly higher than 73.74% （33/45） in the control group （P＜0.05）. After treatment， PR and PR + NP significantly increased in both groups， and were much higher in the treatment group than in the control group （P＜0.05）. The scores of lumbar and knee soreness， emotional disturbance， cold sperm， chest and rib-side and lesser abdomen distension and pain， frequent sighing， and the total TCM syndrome score in the treatment group decreased after treatment （P＜0.05）； and except for cold sperm， the scores of other symptoms mentioned above as well as the total TCM syndrome score in the treatment group were lower than those in the control group （P＜0.05）. The scores of depression， anxiety and stress of DASS-21 in the treatment group decreased after treatment， and were lower than those in the control group （P＜0.05）. After 6 months of follow-up， the spouses of 5 patients in the treatment group and 3 patients in the control group got pregnant （P＞0.05）. No adverse events occurred in both groups during the treatment， and their vital signs were stable. ConclusionSBYD can obviously improve sperm vitality and effectively improve the clinical symptoms， anxiety and depression， and is safe in treating asthenospermia and infertility with liver constraint and kidney deficiency.

Objective We aimed to investigate the effect of ferroptosis on Shenling Baizhu Powder,a compound prescription of Chinese herbal medicine,in improving testicular spermatogenic function in hyperuricemic mice with spermatogenic dysfunction. Methods Sixty BALB/c mice were randomly divided into normal group,model group,Shenling Baizhu Powder high-,medium-,and low-dose groups (20.14,10.07,5.04 g/kg,by gavage),and ferrostatin-1(Fer-1) group (0.8 mg/kg,by tail vein injection),with 10 mice each group. Except for the normal group,the other groups were intraperitoneally injected with potassium oxonate suspension[600mg/(kg·d)]for 7 days to establish the hyperuricemic model,and then the corresponding intervention was given for consecutive 14 days. Content of serum uric acid (UA),testicular Fe2+,reduced glutathione (GSH),malondialdehyde (MDA) and superoxide dismutase (SOD) activity were detected by biochemical method. Epididymal and testicular indices were measured. The spermatogenic function of testes was evaluated by eosin-hematoxylin staining. Sperm quality was detected by an automatic animal sperm analyzer. Prussian blue staining was used to detect iron deposition in testicular tissue. Immunohistochemistry was used to detect the related protein expressions of acyl-coenzyme A synthetase long-chain family member 4 (ACSL4) and glutathione peroxidase 4 (GPX4) in testicular tissue. Western blotting was used to detect the related protein expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1(HO-1)/GPX4 signaling pathway in testicular tissue. Results Compared with the normal group,the contents of serum UA,MDA,and Fe2+in the testis tissue of the model group were increased,the GSH content and SOD activity were decreased,the epididymal and testicular index,testicular spermatogenic function,sperm density and activity rate were decreased,and the iron deposition and ACSL4 protein expression in the testis tissue were increased. The expressions of kelch-like ECH-associated protein-1 (Keap1) and Nrf2 were increased. The expressions of nuclear Nrf2,HO-1,GPX4,and recombinant solute carrier family 7 member 11 (SLC7A11) protein were decreased (P<0.01). Compared with the model group,the above indexes in the Shenling Baizhu Powder groups and the Fer-1 group were improved to varying degrees (P<0.05,P<0.01). Conclusion Shenling Baizhu Powder can inhibit the ferroptosis of testicular cells through the Nrf2/HO-1/GPX4 signaling pathway,and improve the testicular spermatogenic function of mice with hyperuricemia spermatogenic dysfunction.
