Diabetic kidney disease （DKD） stands as one of the most prevalent microvascular complications of diabetes，noted for its concealed onset and tendency to evolve into end-stage renal disease，profoundly impacting patients' life expectancy and quality of life. Epithelial-to-mesenchymal transition （EMT） is a central pathological process in the initiation and progression of DKD，facilitating disease advancement and renal fibrosis，thus representing a crucial focus of research into the pathological mechanisms of DKD. EMT is driven by the abnormal activation of signaling pathways，including transforming growth factor-β （TGF-β）/Smad，secreted glycoprotein/β-catenin，Notch，tumor necrosis factor-α （TNF-α）/nuclear factor-κB （NF-κB），and phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR），leading to renal cellular injury and subsequently accelerating renal fibrosis and the progression of DKD. Traditional Chinese medicine （TCM），characterized by its multi-target and multi-pathway therapeutic approach，demonstrates unique advantages in addressing DKD and EMT. Recent research has shown that active ingredients in TCM，including glycosides，flavonoids，and polyphenols，as well as TCM formulas，can precisely target these relevant signaling pathways，effectively inhibiting cellular injury in DKD and intervening in the EMT process. These findings not only underscore the potential of TCM monomers and formulas in treating DKD and EMT but also pave new directions for research in this field within TCM. This paper systematically reviewed the signaling pathways associated with EMT and provided an in-depth analysis of the research achievements and underlying mechanisms of TCM monomers and formulas in treating DKD and intervening in EMT，aiming to offer new insights and directions for TCM in the treatment of DKD and research on EMT，thereby further promoting the modernization and development of TCM.

Objective:To study the magnetic resonance imaging (MRI) and clinical manifestations of intraspinal echinococcosis.Methods:The general conditions, MRI and clinical manifestations of 23 patients with intraspinal echinococcosis diagnosed by pathology at the First Affiliated Hospital of Xinjiang Medical University from September 2011 to May 2023 were retrospectively analyzed.Results:There were 10 males and 13 females of the 23 patients with intraspinal echinococcosis. The age of the patients was (44.1 ± 13.9) years old, with a median age of 41 years old and a range of 25 to 72 years old. Eleven patients (47.8%) had a history of echinococcosis in the spine or other parts of the body. Among the 23 patients with intraspinal echinococcosis, 12 cases (52.2%) involved thoracic segment, 6 cases (26.1%) involved lumbar segment, 1 case (4.3%) involved sacral segment, 1 case (4.3%) involved thoracolumbar segment, 2 cases (8.7%) involved lumbosacral segment, and 1 case (4.3%) involved cervical and lumbar segment. There were 2 cases (8.7%) involving the intramedullary, 9 cases (39.1%) involving the extramedullary subdural, and 12 cases (52.2%) involving the extramedullary epidural. At the same time, 18 cases (78.3%) involved adjacent vertebral bodies, accessories or surrounding soft tissues. Intramedullary cystic echinococcosis was characterized by multiple nodules at the lower end of the spinal cord and the cauda equina nerve on MRI, with equal or low signal on T1WI, slightly high signals on T2WI and short time of inversion recovery (STIR), accompanied by small vesicles with high signal on T2WI. Intramedullary alveolar echinococcosis was characterized by nodular T1WI signals, slightly lower signals on T2WI and STIR, and circular enhancement on enhanced scan. Extramedullary subdural echinococcosis was mostly manifested as oval small vesicles with low signal on T1WI and high signal on T2WI, with a grape string-like appearance, and the capsular wall with low signal on T2WI could be seen at the edge. Extramedullary epidural echinococcosis was manifested as slightly low signal on T1WI, high signals on T2WI and STIR, accompanied by single or multiple small vesicles with high signal on T2WI, and compression of the dural sac. The clinical manifestations were chest and back, lumbosacral pain in 21 cases (91.3%), and lower limb dysfunction in 6 cases (26.1%).Conclusions:Intraspinal echinococcosis is relatively rare compared with other sites. When MRI features are clear, typical clinical manifestations are present, or there is a history of echinococcosis in other sites, intraspinal echinococcosis should be considered.

Objective: To investigate the clinical effects of one-stage revision combined with intra-articular infusion of vancomycin in the treatment of chronic prosthetic joint infection (PJI) caused by Enterococcal. Methods: From May 2013 to June 2020,the clinical data of 9 patients (2 males and 7 females) with chronic Enterococcal PJI treated with one-stage revision using intra-articular infusion of vancomycin at Department of Orthopaedics,First Affiliated Hospital of Xinjiang Medical University were retrospectively analyzed,including 8 hips and 1 knee.A total of 9 patients with age of (63.9±11.7)years (range:43 to 76 years) were included, and the body mass index was (23.6±4.3)kg/m² (range:18 to 30 kg/m²).There were 6 cases with antibiotic history and 5 cases with sinus tract.The joint fluid,infected tissue around the prosthesis and ultrasonic shock fluid of the prosthesis were collected during operation for microbial culture identification and drug sensitivity test.After thorough debridement of the infected site and removal of the infected prosthesis,a new prosthesis was implanted,then the drainage tube in the operation area was placed.After surgery,vancomycin(1.0 g,q12 h) was combined with intra-articular vancomycin(0.5 g,qd) in monomicrobial PJI,and vancomycin(1.0 g,q12 h) was combined with intra-articular vancomycin (0.5 g,qd) and imipenem/meropenem (0.5 g,qd),and the interval between the two drugs was 12 hours in polymicrobial PJI.Hip and knee functions were evaluated by Harris Hip Score or Knee Society Score(KSS),respectively.The comparison of hip function scores before and after operation was performed by paired t-test. Results: All patients were followed up for (60±39)months(range:24 to 110 months).Two cases were infected with Enterococcus faecium and 7 cases were infected with Enterococcus faecalis.There were 7 cases of monomicrobial infection and 2 cases of polymicrobial infection.Erythromycin(5/9),tetracycline(4/9),ciprofloxacin and β-lactam antibiotics(3/9) were the top three antibiotics in Enterococci resistance rate.The sensitive antibiotics for Enterococcal were vancomycin,linezolid and tigecycline.The average duration of intravenous antibiotics was (14±1)days (range:13 to 17 days),and the average duration of antibiotics in articular cavity was (15±2)days(range:11 to 20 days).Mean duration of oral antibiotic use after discharge was (2±1)months(range:1 to 3 months).One case of polymicrobial PJI treatment failed,with a failure rate of 1/9.At last follow-up,the Harris score of patients with hip PJI increased from (43±6)points to (84±6)points(t=-11.899, P<0.01). KSS score of knee function was improved from 33 point pre-operatively to 85 point post-operatively;overall function score was improved from 35 point pre-operatively to 80 point post-operatively.During the treatment,no formation of sinus tract of the hip joint caused by a catheter,skin necrosis at the knee puncture site or leakage of joint fluid;no complications such as deep vein thrombosis and pulmonary embolism occurred. Conclusions: One-stage revision combined with intra-articular infusion of vancomycin can achieve acceptable infection control rate and joint function in patients with chronic Enterococcus PJI.However,the treatment of polymicrobial PJI still needs to be further verified.

Objective:To investigate the performance of a predictive model based on fat suppression (FS)-T2WI sequence combined with machine learning in the differential diagnosis of brucellar spondylitis (BS) and tuberculous spondylitis (TS).Methods:The clinical and imaging data of 74 patients with BS and 81 patients with TS diagnosed clinically or pathologically in the First Affiliated Hospital of Xinjiang Medical University from January 2017 to January 2022 were retrospectively analyzed, and all patients underwent spinal magnetic resonance imaging (MRI) examination before treatment. Patients were randomly divided into a training group ( n = 123) and a testing group ( n = 32) in an 8 ∶ 2 allocation ratio, and radiomics feature extraction and dimensionality reduction analysis were performed on FS-T2WI sequence images. Four machine learning algorithms, including K-nearest neighbor (KNN), support vector machine (SVM), random forest (RF) and logistic regression (LR), were used to construct a radiomics model, and receiver operating characteristic (ROC) curve was used to analyze the differential diagnostic performance of each model for BS and TS. Results:A total of 1 409 radiomics features were extracted, and 7 related features were screened and included for identification of BS and TS, among which the Maximum2DDiameterColumn feature value showed a strong correlation, and there was a statistically significant difference between BS and TS patients ( P < 0.001). In the testing group, the area under the ROC curve (AUC) value of the SVM model for identifying BS and TS was 0.886, with a sensitivity of 0.53, a specificity of 0.88, and a diagnostic accuracy of 0.81; in the training group, the AUC value of the SVM model for identifying BS and TS was 0.811, the sensitivity was 0.68, the specificity was 0.72, and the diagnostic accuracy of the model was 0.78. Conclusion:The prediction model based on FS-T2WI sequence combined with machine learning can be used to identify BS and TS, and the diagnostic performance of SVM model is prominent and stable.

Objective:To investigate the gender differences in serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), platelet (PLT), fibrinogen (FIB) and D-dimer for the diagnosis of chronic periprosthetic joint infection (PJI).Methods:A total of 470 patients who underwent revision arthroplasty in the Department of Joint Surgery, First Affiliated Hospital of Xinjiang Medical University from January 2013 to December 2021 were retrospectively analyzed. According to gender and diagnosis, they were divided into four groups: 78 cases of male chronic PJI, 108 cases of male aseptic loosening, 95 cases of female chronic PJI, and 189 cases of female aseptic loosening. The serological results of CRP, ESR, PLT, FIB and D-dimer were collected before operation. The receiver operating characteristics (ROC) curves were used to determine the optimal cut-off values of CRP, ESR, PLT, FIB and D-dimer for the diagnosis of chronic PJI in different genders, and to calculate their sensitivity and specificity. The diagnostic efficacy of the index was analyzed by comparing the area under curve (AUC) of different indicators.Results:The levels of ESR, PLT and D-dimer in the male chronic PJI group were 43 (20.0, 52.5) mm/1 h, 249×10 9 (204×10 9, 306×10 9) /L, 449 (219,833) μg/L, respectively, which were lower than those in the female group of 56 (40, 65) mm/1 h, 295×10 9 (228×10 9, 364×10 9) /L, and 645 (345, 1 157) μg/L, with statistically significant differences ( Z=-4.17, P<0.001; Z=-2.17, P=0.030; Z=-2.82, P=0.005). The AUC of CRP in the male chronic PJI group was 0.841, which was higher than the AUC of the other four indicators; CRP was combined with ESR, PLT, FIB and D-dimer to establish a joint prediction model for male chronic PJI. The ROC curve showed that the combination of CRP+FIB had a maximum AUC [0.849, 95% CI (0.79, 0.91)], sensitivity of 80% and specificity of 86%. The AUC of CRP in the female chronic PJI group was 0.866, which was higher than the AUC of the other four indices; CRP was combined with ESR, PLT, FIB and D-dimer to establish a combined prediction model for female chronic PJI. The ROC curve showed that the combination of CRP+PLT had the maximum AUC [0.883, 95% CI (0.84, 0.93)], sensitivity of 87% and specificity of 79%. Conclusion:Serologic indicators in patients with chronic PJI are gender-specific. CRP combined with FIB has the highest diagnostic value for the chronic PJI in males, while CRP combined with PLT has the highest diagnostic value for the chronic PJI in females.

Objective:To investigate the diagnostic value of plasma fibrinogen (FIB) in chronic periprosthetic joint infection (PJI).Methods:A total of 470 patients who underwent revision hip and knee arthroplasty after primary hip and knee arthroplasty in the First Affiliated Hospital of Xinjiang Medical University from January 2013 to December 2021 were retrospectively analyzed. According to the diagnosis of the disease, 173 patients (112 hips and 61 knees) were divided into chronic PJI group, including 78 males and 96 females, aged 65 (53, 72) years; and 297 patients (216 hips and 81 knees) were divided into aseptic loosening group, including 108 males and 189 females, aged 63 (50, 72) years. The preoperative levels of FIB, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), D-dimer and platelet were compared between the two groups, and the sensitivity and specificity of the diagnosis of chronic PJI were calculated. Receiver operating characteristic (ROC) curves were used to determine the optimal cut-off values of FIB, CRP, ESR, platelet and D-dimer for the diagnosis of chronic PJI. The diagnostic efficacy of each indicator was analyzed by comparing the area under curve (AUC) and using a combined diagnostic test.Results:FIB, CRP, ESR, platelets and D-dimer in the chronic PJI group were 4.05 (3.52, 4.72) g/L, 19.5 (10.7, 40.0) mg/L, 50 (28, 60) mm/1 h, 270 (221, 351)×10 9 /L, 514 (261, 873) μg/L, respectively, which were higher than 3.25 (2.80, 3.63) g/L, 3.7 (2.0, 6.7) mg/L, 20 (12, 30) mm/1 h, 225 (182, 269)×10 9 /L, and 310 (167, 569) μg/L in sterile loosening group, with statistically significant differences ( P<0.05). The AUC of FIB, CRP, ESR, platelets and D-dimer in the diagnosis of chronic PJI were 0.78 (95% CI: 0.73, 0.82), 0.86 (95% CI: 0.82, 0.89), 0.80 (95% CI: 0.76, 0.85), 0.68 (95% CI: 0.63, 0.73), 0.64 (95% CI: 0.59, 0.69); the optimal cut-off values were 3.73 g/L, 9.64 mg/L, 39 mm/1 h, 280×10 9 /L, 624 μg/L; the sensitivity was 68%, 79%, 69%, 47%, 43%; the specificity was 81%, 85%, 85%, 81%, 79%, respectively. When CRP, ESR, FIB, platelets and D-dimer were combined sequentially to diagnose patients with chronic PJI, the sensitivity and specificity of the series test were 12.7% and 99.7%, and those of the parallel test were 100% and 37.3%. The combined diagnostic test showed that the maximum AUC of FIB combined with CRP was 0.85 (95% CI: 0.81, 0.89), with a sensitivity of 76% and a specificity of 89%. Conclusion:The clinical value of plasma FIB in the diagnosis of chronic PJI is not superior to that of CRP and ESR, but the combination of FIB and CRP can improve the specificity.

Objective: Buyinqianzheng Formula (BYQZF) is clinically employed in traditional Chinese medicine to treat Parkinson's disease (PD) by improving mitochondrial dysfunction. However, the underlying mechanisms by which BYQZF affects mitochondrial morphology remain unknown. Therefore, we observed the effects of BYQZF on mitochondria from the perspective of the PINK1/Parkin pathway. Methods: Cell survival rates were assessed by Cell Counting Kit-8 assay. Expression levels of PINK1 and Parkin mRNA were examined by qRT-PCR. Protein expression levels of PINK1, PINK1-Ser228, Parkin, Parkin-Ser65, Drp1, and Drp1-Ser637 were examined by western blotting. PINK1, Parkin, and Mito-Tracker? Red CMXRos (MTR) were stained by triple-labeled immunofluorescence, and observed under laser confocal microscopy. Results: Cell survival rate, mitochondrial form factor, mean length and number of mitochondrial network branches, mitochondrial activity, mRNA expression levels of PINK1 and Parkin, and protein expression levels of PINK1, Parkin, and Drp1-Ser637 were reduced after 1-methyl-4-phenylpyridinium (MPP+) intervention. In contrast, Pearson's correlation coefficients between PINK1 and Parkin, and between Parkin and MTR, as well as protein expression levels of PINK1-Ser228, Parkin-Ser65, and Drp1 increased significantly after MPP+intervention. Treatment with BYQZF increased cell survival rate, mitochondrial form factor, mean length and number of mitochondrial network branches, mitochondrial activity, mRNA expression levels of PINK1 and Parkin, and expression of PINK1, Parkin, and Drp1-Ser637 proteins. Pearson's correlation coefficients between PINK1 and Parkin, and between Parkin and MTR, as well as protein expression levels of PINK1-Ser228, Parkin-Ser65, and Drp1 decreased after BYQZF treatment. Conclusion: These results demonstrate that BYQZF has a protective effect on mitochondrial molecular mechanisms in the PD cell model, and the mechanism is related to the PINK1/Parkin pathway.

Objective: To discuss the affect of glycosylated hemoglobin (HbA1c) level for the onset of nonalcoholic fatty liver disease (NAFLD) in cohort population. Methods: An epidemiological survey of the relationship between HbA1c and NAFLD conducted in 2012 was based at cohort baseline, and three follow-up sessions conducted in 2013, 2014 and 2015. In total 2 811 subjects were included in the study after exclusion of NAFLD patients at baseline and those who lost their lives due to relocation, and death. The Cox proportional hazard model was used to analyze the relationship between glycosylated hemoglobin and other risk factors of NAFLD. Continuous variables were compared using the t-test or the Mann-Whitney test. χ ²-test was used for the measurement of categorical data. Results: A total of 2 811 subjects with mean age of 59 (58.2±9.8) years old, including 1 664 males and 1 147 females. Age, waist circumference, body mass index, systolic blood pressure, γ-glutamyltransferase and fasting blood glucose level of HbA1c abnormal group were higher than normal group. The incidence of NAFLD in the abnormal HbA1c level group (25.4%) was higher than normal group (14.9 %), and diastolic blood pressure, high-density lipoprotein cholesterol was lower than normal group and the differences were statistically significant. During the three follow-up intervals, there were 440 new cases of NAFLD, consisting 285 males and 155 females with cumulative incidence of 15.7% (440/2 811). Multivariate Cox regression analysis showed that patients with elevated HbA1c had a higher risk of developing NAFLD (HR 1.796; 95% CI 1.335~2.418; P < 0.01), and the increased HbA1c level after adjustment for gender, age, and metabolic syndrome-related factors remained an independent risk factors for NAFLD (HR 1.580; 95.0% CI 1.161-2.152; P < 0.01). Conclusion An elevated HbA1c levels have a positive predictive value for the onset of NAFLD.
