Methods: This retrospective study analyzed 32 consecutive IDS patients who underwent UEDD surgery. Clinical features, laboratory data (erythrocyte sedimentation rate and C-reactive protein), and treatment outcomes were analyzed. Results: Definite microorganisms were identified in 27 patients (84.3%), with 24 (88.9%) meeting cure criteria. The cure rate was significantly higher in the detected pathogen group compared to the undetected pathogen group (88.9% vs. 80%; χ²=19.36, p<0.0001). Metagenomic next generation sequencing (mNGS) provided faster diagnosis (41.72±6.81 hours) compared to tissue culture (95.74±35.47 hours, p<0.05). The predominant causative pathogen was Mycobacterium tuberculosis, followed by Staphylococcus aureus. Significant improvements were observed in Visual Analog Scale pain scores, from a mean of 7.9 preoperatively to 1.06 at 1 year postoperatively. The Oswestry Disability Index revealed a similar trend, showing significant improvement (p<0.05). Conclusions UEDD is a viable alternative to traditional open surgery for managing IDS in high-risk patients. UEDD offers a dual therapeutic-diagnostic advantage during the initial admission phase, enabling simultaneous debridement, neurological decompression, and targeted biopsy in a single intervention. Compared with traditional tissue culture, mNGS enables rapid microbiological diagnosis and extensive pathogen coverage.

Objective To explore the value of serum soluble transferrin receptor(sTFR)and urinary tryp-sin inhibitor(Bikunin)in assessing the short-term prognosis of patients with hepatitis B virus related acute on chronic live failure(HBV-ACLF).Methods A total of 103 patients with HBV-ACLF admitted to Weifang People's Hospital from January 2019 to December 2022 were collected as HBV-ACLF group,who were classi-fied into early stage group(n=46),middle stage group(n=34)and late stage group(n=23)according to the disease progression,and classified into good prognosis group(n=67)and poor prognosis group(n=36)according to clinical outcomes at 30 d after hospital admission.At the same time,65 patients with chronic hep-atitis B virus infection were selected as chronic hepatitis B group and 65 healthy volunteers were selected as control group were enrolled in the study.The clinical medical records of research objects were collected at the time of admission.Serum sTFR and Bikunin levels were detected by enzyme-linked immunosorbent assay.Spearman rank correlation analysis was performed to analyze the association between serum sTFR,Bikunin and disease progression.Multivariate Logistic regression analysis was performed to analyze factors affecting short-term poor prognosis of patients with HBV-ACLF.Receiver operating characteristic(ROC)curve was used to assess the predictive value of serum sTFR and Bikunin on prognosis.Results Serum sTFR and Bikun-in levels were lower in HBV-ACLF group and chronic hepatitis B group than those in control group,and those in HBV-ACLF group were lower than those in chronic hepatitis B group,and the differences were statistically significant(P＜0.05).Model for End-Stage Liver Disease(MELD)score was higher in HBV-ACLF group and chronic hepatitis B group than that in control group,and that in HBV-ACLF group was higher than that in chronic hepatitis B group,and the differences were statistically significant(P＜0.05).Compared with early stage group,serum sTFR and Bikunin levels decreased in middle stage group and late stage group,and those in late stage group were lower than those in middle stage group,and the differences were statistically significant(P＜0.05).MELD score increased in middle stage group and late stage group,and that in late stage group was higher than that in middle stage group,and the differences were statistically significant(P＜0.05).Serum sTFR and Bikunin in HBV-ACLF patients were associated with MELD score(r=-0.638,-0.592,P＜0.05),which were also associated with severity of disease(rs=-0.722,-0.671,P＜0.05).Elevated HB-sAg,elevated quantitative HBV DNA,middle and late stages of HBV-ACLF and elevated MELD score were independent risk factors for poor short-term prognosis in patients with HBV-ACLF(OR＞1,P＜0.05),while elevated serum sTFR and Bikunin were protective factors for poor short-term prognosis in patients with HBV-ACLF(OR＜1,P＜0.05).Serum sTFR and Bikunin both had some predictive value for poor short-term prog-nosis,and the predictive value of the combination was greater than that of single indicator(Z=2.139,2.165,P＜0.05).Conclusion Serum sTFR and Bikunin levels are decreased in patients with HBV-ACLF,which are associated with disease progression and short-term prognosis.Early combined detection of two indicators could predict the risk of poor prognosis in patients with HBV-ACLF at 30 d after hospital admission.

Objective:To investigate the anesthetic effects of visual dual lumen bronchial catheter versus conventional dual lumen bronchial catheter in thoracic surgery. Methods:A total of 80 patients who underwent elective thoracic surgery requiring lung isolation at the People's Hospital of Xishuangbanna Dai Autonomous Prefecture from June 2021 to June 2023 were selected for a randomized controlled study. The patients were divided into an observation group and a control group, with 40 patients in each group, using the random number table method. The observation group used a visual dual lumen bronchial catheter, while the control group used a conventional dual lumen bronchial catheter. The two groups were compared regarding positioning time for intubation, number of cases with catheter displacement, repositioning time, vital signs during intubation, and the occurrence of complications.Results:In the observation group, the average arterial pressure at the time of accurate intubation positioning was (71.92 ± 8.33) mmHg (1 mmHg = 0.133 kPa), and the heart rate was (62.37 ± 12.14) beats/min. These values were significantly lower than those in the control group [(95.27 ± 9.51) mmHg, (88.42 ± 15.08) beats/min, t = 12.56, 15.41, both P < 0.05]. Additionally, the oxygen saturation in the observation group was significantly higher than that in the control group [(99.01 ± 0.32)% vs. (96.67 ± 1.65)%, t = 8.54, P < 0.05]. In the observation group, the positioning time for intubation and the repositioning time after catheter displacement during surgery were (22.54 ± 7.11) seconds and (16.22 ± 12.14) seconds, respectively. These durations were significantly shorter than those in the control group [(74.29 ± 12.52) seconds, (32.74 ± 11.48) seconds, t = 1.14, 5.17, both P < 0.05]. The incidence of postoperative pulmonary infections in the observation group was significantly lower than that in the control group [0 vs. 10.0% (4/40), χ2 = 6.49, P < 0.05]. Conclusion:The use of a visual dual-lumen bronchial catheter for anesthesia intubation in thoracic surgery has a minimal impact on patients' vital signs, along with shorter intubation positioning and repositioning durations, and a lower incidence of pulmonary infection complications compared with the conventional dual-lumen bronchial catheter.

Pelvic floor muscle training (PFMT) is the first-line intervention for non-surgical treatment of female patients with stress urinary incontinence (SUI). However, due to the particularity of the physiological position of the pelvic floor muscles, 13% to 53% of patients are unable to perform PFMT correctly after the initial visit. In view of this, scholars at China and abroad put forward some other sports rehabilitation methods and achieve good clinical results. In this paper, exercise rehabilitation methods for female SUI patients were reviewed, including PFMT, core muscle training, Pilates, yoga, physical activities, etc., in order to provide reference for medical personnel to formulate scientific and feasible exercise rehabilitation programs for female SUI patients.

Objective To explore the effect of gender,training duration and type of sports on electro-cardiographic changes in Chinese elite athletes by performing electrocardiography(ECG).Methods A to-tal of 891 Chinese elite athletes who underwent ECG examinations between 2016 and 2019 were in-cluded in the study.The ECGs were divided into three groups according to the guidelines of the Euro-pean Society of Cardiology(ESC)in 2010:group 0(normal ECG),group 1(common and training-relat-ed ECG)and Group 2(uncommon and training-unrelated ECG).The effect of gender,training dura-tion(4 to 6 years,7 to 10 years and more than 11 years)and sports types(skill,strength,endur-ance and mixed categories)on the ECG changes was assessed.Results No significant differences were found in Group 2 in sex,training duration or sports types.However,the prevalence of common train-ing-related ECG changes was significantly higher in male athletes than in female athletes(58.9%vs.47.4%).Moreover,the highest prevalence was found in athletes with more than 11 years of training,significantly higher than those with 4-6 years of training(P<0.05).A highly significant difference was also observed among athletes of different sports(P<0.01),with the highest in those of the mixed cate-gory at 64.6%.Moreover,sinus bradycardia occurred with significantly higher incidence in athletes un-dertaking mixed and endurance training than others(P<0.05).Conclusion The training-related ECG changes of Chinese elite athletes is closely correlated to their gender,training duration and sports types.

Objective To analyze the serum differential metabolites and metabolic pathways of patients with refractory gout of spleen deficiency and damp-heat type by metabolomics based on 1 H-NMR.Methods A total of 40 patients with refractory gout acute attack of spleen deficiency and damp-heat type were selected as gout group,and 20 healthy subjects were selected as healthy group.Erythrocyte sedimentation rate and serum C-reactive protein(CRP),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),serum adiponectin and creatinine levels were used as observation indicators.Serum metabolomics analysis was performed using 1 H-NMR method.The obtained data were subjected to principal component analysis(PCA)and orthogonal partial least squares discriminant analysis(OPLS-DA)to determine the corresponding metabolites and analyze the potential metabolic pathways of the differential metabolites.Results Compared with the healthy group,the erythrocyte sedimentation rate,serum CRP,IL-6,TNF-α and other inflammatory indicators and cell chemokine levels in the gout group were significantly increased(P＜0.01);the serum adiponectin level was significantly decreased(P＜0.01),and the serum creatinine level was significantly increased(P＜0.01).There were significant differences in the content of serum metabolites between the healthy group and the gout group.A total of 44 differential metabolites were obtained,involving 12 potential metabolic pathways such as aminoacyl tRNA biosynthesis,valine,leucine and isoleucine biosynthesis,alanine,aspartic acid and glutamic acid metabolism,glycolysis/gluconeogenesis,ketone synthesis and degradation,citric acid cycle(TCA cycle),glutathione metabolism,glyceride metabolism.Conclusion Acute attacks of refractory gout with spleen deficiency and damp-heat type may be associated with disorders of mitochondrial energy metabolism,leading to abnormalities in glucose metabolism,lipid metabolism,and amino acid metabolism.

Aim To investigate the correlation between serum remnant lipoprotein cholesterol(RLP-C),triglyc-eride levels(TG)and coronary heart disease(CHD)in middle-aged people.Methods A total of 439 middle-aged in-dividuals who were hospitalized in the Department of Cardiology of Liuzhou People's Hospital from January 2015 to Decem-ber 2022 and underwent coronary angiography were selected as the research subjects.They were divided into CHD group(190 cases)and control group(249 cases)according to the results of coronary angiography.The general clinical data and laboratory tests of the subjects were collected,and RLP-C was calculated based on blood lipid profile.Bivariate Spearman correlation,multivariate Logistic regression,and restricted cubic spline graph were used to analyze the correlation between RLP-C,TG,and CHD in these middle-aged participants.Receiver operating characteristic(ROC)curve was used to evaluate the value of RLP-C and TG in predicting CHD.Results The age in CHD group was older than that in control group,proportion of male,proportion of smoking history,incidence of hypertension,incidence of diabetes,inci-dence of hyperlipidemia,body mass index(BMI),systolic blood pressure(SBP),fasting blood glucose(FBG),glycosy-lated hemoglobin(HbA1c),TG,low density lipoprotein cholesterol(LDLC),RLP-C were higher than those in control group,while high density lipoprotein cholesterol(HDLC)was lower than that in control group(P＜0.05).The Spearman correlation analysis results showed positive correlation between RLP-C,TG,LDLC and CHD(r=0.227,0.279,and 0.105,respectively,P＜0.05),and negative correlation between HDLC and CHD(r=-0.340,P＜0.001)in these stud-ied population.Multivariate Logistic regression analysis showed that whether as continuous or categorical variables,RLP-C and TG were independent risk factors for CHD(P＜0.05),HDLC was independent protective factor for CHD(P＜0.05).Compared with lowest quartile group,The OR(95％CI)of CHD incidence in 3rd and 4th quartile group of RLP-C were 2.648(1.364～5.144)and 2.847(1.468-5.520)respectively;The OR(95％CI)of CHD incidence in 3rd and 4th quartile group of TG were 3.043(1.520-6.092)and 3.520(1.811～6.842)respectively.The restricted cubic spline graph revealed that RLP-C,TG were positively nonlinearly correlated with CHD(P for overall＜0.001,P for nonlin-ear=0.002,0.001,respectively).Subgroup analysis showed that the relationship between RLP-C,TG and CHD was more significant in females than in males.ROC curve analysis showed that the areas under the curve(95％CI)of RLP-C,TG in predicting CHD were 0.632(0.580-0.685)(P＜0.001)and 0.663(0.612-0.713)(P＜0.001)in general,meanwhile,0.735(0.659-0.811)(P＜0.001)and 0.740(0.666-0.813)(P＜0.001)in females.Conclusion RLP-C and TG are independent risk factors for CHD in middle-aged people,and their correlation with CHD are greater than that of LDLC.They may become the main targets for the prevention and treatment of CHD,and should be given clinical attention.

Objective:To explore the value of amide proton transfer-weighted (APTw) imaging and intravoxel incoherent motion (IVIM) imaging for diagnosing and evaluating the pathological differentiation of cervix squamous cell carcinoma (CSCC).Methods:This study was a diagnostic trial. Totally 56 patients pathologically diagnosed with CSCC at the First Hospital of Lanzhou University from October 2021 to October 2022 were retrospectively collected, as the CSCC group. And 36 female healthy volunteers who underwent physical examinations at the First Hospital of Lanzhou University from October 2021 to October 2023 were recruited as the control group. CSCC patients were divided into well-moderately differentiated ( n=34) and poorly differentiated groups ( n=22). The region of interest was placed in the lesions of CSCC group and normal cervical stroma of control group, and the quantitative parameters for asymmetric magnetization transfer ratio (MTR asym) of APTw imaging and pure diffusion coefficient (D), false diffusion coefficient (D *) and perfusion fraction (f) for IVIM were obtained. The independent sample t test was used to compare the differences in quantitative parameters between the two groups, the logistic regression model was used to establish combined parameters for the quantitative parameters with statistical significance between the two groups. The receiver operator characteristic curve was used to evaluate the diagnostic efficacy of single quantitative parameters and combined parameters to distinguish the CSCC group from the control group, and the well-moderately differentiated group from the poorly differentiated group in CSCC patients. The area under the curve (AUC) was compared using the DeLong test. Results:There were significant differences in MTR asym, D and f between CSCC group and control group ( t=-9.79, 10.09, 11.35, P<0.001). Also, significant differences were found for MTR asym and D between the well-moderately differentiated and poorly differentiated group ( t=4.11, -3.76, P<0.001). There was no significant difference in other quantitative parameters ( P>0.05). When comparing the CSCC group and control group, the AUC (95% CI) of MTR asym, D, f and combined parameter (MTR asym+D+f) were 0.887 (0.804-0.944), 0.940 (0.871-0.979), 0.968 (0.909-0.993), 0.995 (0.950-1.000). The AUC of the combined parameter was higher than those of MTR asym and D, with statistical significance ( Z=3.07, 2.06, P=0.002, 0.040). When comparing the well-moderately differentiated and poorly differentiated group, the AUC (95% CI) of MTR asym, D, and combined parameter (MTR asym+D) were 0.789 (0.660-0.887), 0.775 (0.644-0.876), 0.852 (0.731-0.932). There was no significant difference between each two AUCs ( P>0.05). Conclusion:The quantitative parameters of APTw and IVIM imaging can be used to diagnose and preliminarily evaluate the pathological differentiation of CSCC. Joint parameters can improve the diagnostic efficiency of CSCC.
