Objective To compare the differences in clinical features and treatment choices between periph-eral spondyloarthritis(pSpA)and axial spondyloarthritis(axSpA),and better understand the clinical charac-teristics and medication needs of pSpA.Methods Our study is a retrospective cohort study.The patients who first visited the First Medical Center of Chinese PLA General Hospital between January 2016 and December 2022 and were diagnosed with axSpA or pSpA according to the classification criteria established by the Assess-ment of SpondyloArthritis International Society were selected as the study subjects.Demographic data,clinical characteristics,laboratory tests,and treatment information of these patients were obtained through the electronic medical records management system and the intelligent management system for spondyloarthritis.The research compared the distribution of swollen and tender joints between pSpA and axSpA patients,as well as that between pSpA1(excluding patients with psoriatic arthritis)and axSpA patients.Additionally,we analyzed differences in clinical features and treatment options among these groups.Results A total of 1639 pa-tients were included in the study,of which 184 had pSpA(including 97 with psoriatic arthritis),and 1455 had axSpA.Compared to axSpA patients,pSpA patients had fewer male patients(62.5％vs.79.7％,P＜0.001),later onset age(33.8 years vs.22.0 years,P＜0.001),shorter diagnostic delays(6.0 months vs.14.2 months,P=0.004),more associated peripheral arthritis(71.7％vs.9.3％,P＜0.001)and dac-tylitis(6.5％vs.0.3％,P＜0.001),more cases of psoriasis(52.7％vs.1.1％,P＜0.001)and a more common family history of psoriasis(11.4％vs.3.4％,P＜0.001).pSpA patients had higher levels of in-flammatory markers but a lower positive rate of human leukocyte antigen(HLA)-B27(43.5％vs.87.4％,P＜0.001).A positive HLA-B27 was associated with an earlier onset age,fewer cases of psoriasis,and a fami-ly history of ankylosing spondylitis.pSpA patients had a higher proportion of using conventional synthetic dis-ease-modifying antirheumatic drugs(csDMARDs),biologic disease-modifying antirheumatic drugs(bDMARDs),and oral glucocorticoids,and they also more frequently used a combination of bDMARDs and csDMARDs(19.0％vs.12.2％,P=0.009)or multiple csDMARDs(65.8％vs.12.5％,P＜0.001).Compared to axSpA patients,pSpA1 patients(excluding psoriatic arthritis)did not show significant differences in the prevalence of psoriasis,uveitis,family history of psoriasis,or the use of bDMARDs,but the subgroup analysis of other variables was consistent with the results of pSpA patients.Conclusions pSpA patients tend to have a later onset of disease,a lower proportion of male and HLA-B27 positivity,more associ-ated peripheral arthritis,dactylitis,psoriasis,and a more common family history of psoriasis.The disease bur-den in terms of treatment for pSpA is not lower than that for axSpA.Due to the presence of more peripheral symptoms,psoriasis,and higher levels of inflammation,they also require more medication.

Objective:To explore the correlation between serum nidogen-2 (NID-2) and thoracic aortic calcification in patients with chronic kidney disease (CKD), and construct a risk prediction model based on NID-2 to evaluate its value in predicting the risk of the severe thoracic aortic calcification and cardiovascular and cerebrovascular events in CKD patients.Methods:It was a prospective cohort study. Patients with CKD at stage 3 to 5D in the Zhongda Hospital Affiliated to Southeast University from January 2022 to January 2023 were enrolled. Syngo.via software was used to evaluate the volume of thoracic aortic calcification, and enzyme-linked immunosorbent assay was employed to determine the level of serum NID-2. According to the volume of thoracic aortic calcification, the patients were divided into three groups: no calcification group, mild calcification group and severe calcification group. The top 25% of the patients were defined as no or mild calcification group, and the latter 75% were defined as severe calcification group. The follow-up period was one year. During the follow-up period, cardiovascular and cerebrovascular events, as well as all-cause death among the enrolled patients were recorded. Logistic regression analysis was used to screen the influencing factors of thoracic aortic calcification. Based on the results of logistic regression analysis, a nomogram prediction model was constructed. The receiver operating characteristic curve (ROC curve), calibration curve, and decision curve were employed to evaluate the discrimination, calibration and clinical practicality of the nomogram model.Results:A total of 132 patients were included, with 91 males (68.94%) and age of (56.51±16.37) years. There were 60 CKD 3-5 stage patients (non-dialysis, 45.45%) and 72 CKD 5D patients (dialysis, 54.55%). Serum ND-2 levels differed significantly among healthy individuals, dialysis patients and non-dialysis patients ( H=70.651, P<0.001). There was no statistically significant difference in serum NID-2 level between the no or mild calcification group and the severe calcification group in dialysis patients ( Z=350.00, P=0.426). The serum NID-2 level in the severe calcification group was significantly higher than that in the no or mild calcification group in non-dialysis patients ( Z=242.00, P=0.019). In non-dialysis patients, there was a statistically significant correlation between serum NID-2 level and volume of thoracic aortic calcification ( r=0.40, P<0.001). In dialysis patients, there was no statistically significant correlation between serum NID-2 level and volume of each segment of thoracic aortic calcification (all P>0.05). The univariate logistic regression analysis showed that, age, hemoglobin, serum albumin, estimated glomerular filtration rate, NID-2, hypertension, type 2 diabetes mellitus and cerebral infarction were correlated factors of thoracic aortic calcification in non-dialysis patients (all P<0.05). Multivariate logistic regression analysis showed that age ( OR=1.22, 95% CI 1.08-1.50, P=0.010) was an independent correlated factor of thoracic aortic calcification in non-dialysis patients. The above related variables of univariate logistic regression analysis were incorporated into a nomogram to construct a predictive model for severe vascular calcification in non-dialysis patients, yielding an AUC of 0.94 (95% CI 0.89-0.99) in ROC curve, with a sensitivity of 83% and a specificity of 95%. A nomogram model based on above variables for predicting cardiovascular and cerebrovascular events in non-dialysis patients demonstrated an AUC of 0.95 (95% CI 0.90-1.00) in ROC curve, with a sensitivity of 95% and a specificity of 87%. Conclusions:In non-dialysis patients, serum NID-2 level in the severe calcification group is significantly higher than that in the no or mild calcification group. The serum NID-2 is a related factor of thoracic aortic calcification and cardiovascular and cerebrovascular events in non-dialysis patients. The nomogram prediction model constructed by combining NID-2 with age, hemoglobin, serum albumin, estimated glomerular filtration rate, hypertension, type 2 diabetes mellitus and cerebral infarction has a high predictive value for the risk of thoracic aortic calcification as well as cardiovascular and cerebrovascular events in non-dialysis patients.

Objective To investigate the effects of different use methods of tourniquet on hidden blood loss and knee joint swelling in total knee arthroplasty(TKA),and to explore its potential benefits for postoperative rehabilitation.Methods A prospective study was conducted from March 2018 to March 2023 in Xuzhou Municipal Hospital Affiliated to Xuzhou Medical University,involving 131 patients who underwent TKA.The patients were divided into three groups based on the method of tourniquet use:44 patients routinely used a tourniquet in group A,48 patients only used a tourniquet during the application of bone cement in group B,and 39 patients did not use tourniquet in group C.Operation time,dressing changes,intraoperative blood loss,total blood loss,explicit blood loss,hidden blood loss,percentage of hidden blood loss,postoperative blood transfusion,hemoglobin(Hb),hematocrit(HCT),C-reactive protein(CRP),and creatine kinase(CK)were compared among groups.The pain and functional recovery were evaluated by visual analogue scale(VAS)and knee society clinical rating system(KSS)before surgery,and 3 days,1 month,and 3 months after surgery.The degree of limb swelling and the range of motion of the knee were also compared among groups.Results Group A had shorter operation time and less frequency of postoperative dressing changes than the other two groups(P<0.05).The hidden blood loss and total blood loss in group A were significantly less than those in group C(P<0.05),and the hidden blood loss and total blood loss volume in the three groups from low to high was group A

Objective:To systematically evaluate studies validating the performance of the Global Leadership Initiative on Malnutrition (GLIM) in diagnosing malnutrition.Methods:Seven Chinese and English databases including Embase, Web of Science (WOS), PubMed, CINAHL, Cochrane Library, SinoMed, CNKI, Wanfang Data, and VIP Database were searched for articles on the validation of GLIM criteria published between September 2018 and September 2024. Two researchers independently performed literature screening and data extraction. The concurrent and predictive validity of the criteria was analyzed.Results:A total of 136 papers were included for analysis. The GLIM criteria for diagnosing malnutrition had a sensitivity of 77%, a specificity of 87%, and an area under the curve (AUC) of 0.90. Malnutrition diagnosed by the GLIM criteria predicted prolonged hospital and intensive care unit (ICU) stays, increased readmission and complication rates (both overall and infectious), reduced survivals (median, overall, and disease-free), and increased in-hospital and follow-up mortalities. Both moderate and severe malnutrition predicted decreased overall survival. However, only three studies analyzed the impact of nutritional therapy on the clinical outcomes of malnourished patients.Conclusions:The GLIM criteria accurately differentiate malnutrition and are a valid predictive tool of clinical outcomes. However, the validity criteria in these validation studies were questionable, along with high methodological heterogeneity. Furthermore, there is a lack of studies validating the role of nutritional therapy in improving the clinical outcomes of malnourished patients.

Guided by Academician Zhang Boli's theory of "dampness， turbidity， phlegm， and fluid-related diseases"，this paper elaborated on the pathogenesis and syndrome differentiation treatment of heart failure from the perspective of the "spleen-mitochondria". It analyzed the essential similarities between "spleen-mitochondria" and "dampness， turbidity， phlegm， and fluid-related diseases"， as well as their close association with the onset of heart failure. Furthermore，it explored the connection between spleen function and mitochondrial function in traditional Chinese medicine （TCM），positing that the spleen's role in transportation and transformation is analogous to mitochondrial material metabolism and energy conversion，with spleen deficiency closely related to mitochondrial dysfunction. It thus concluded that mitochondrial material metabolism and energy conversion represent the microscopic essence of the spleen's role in transportation and transformation，and mitochondrial dysfunction is a contributing factor to pathological products like dampness and turbid phlegm，which are closely associated with the occurrence of heart failure. The four elements of dampness，turbidity，phlegm，and fluid are a series of related symptoms resulting from abnormal fluid transportation and transformation，serving as both factors in the onset of heart failure and the core pathological basis for its deterioration. Therefore，during the treatment of heart failure，it is essential to regulate mitochondrial function. Early intervention should focus on eliminating dampness and turbidity to improve mitochondrial function and restore normal energy metabolism. In the middle and late stages，emphasis should be placed on resolving phlegm，promoting blood circulation，warming Yang，and reducing water retention to alleviate mitochondrial damage and improve cardiac function. Supporting Qi and strengthening the spleen should be a continuous approach，and treatment should be adjusted to enhance mitochondrial function and stabilize the condition，thereby improving prognosis. This paper discussed the role of the spleen and mitochondria in the pathogenesis of heart failure，examined the evolution of heart failure mechanisms from the perspective of dampness， turbidity， phlegm， and fluid-related diseases，and proposed a phased treatment strategy. It enriched the theory of dampness， turbidity， phlegm， and fluid-related diseases and offered new strategies for heart failure treatment. However，in practical application，TCM strategies for treating heart failure need to be integrated with modern medical approaches to provide a more solid scientific foundation for treatment.

Objective To investigate the feasibility of simultaneous multi-slice(SMS)acquisition combined with single-shot echo-planar imaging(SSEPI)multi-model diffusion weighted imaging(DWI)for breast lesions.Methods Totally 108 cases of breast lesions were retrospectively enrolled and divided into malignant group(n=66)and benign group(n=42)based on pathology.3.0T MR scanner was used to acquire SSEPI and SMS-SSEPI multi-b values DWI,7 derived parameters were obtained through post-processing with mono-exponential,fractional-order calculus(FROC)and continuous-time random walk(CTRW)models.Then the imaging quality and derived parameters of SMS-SSEPI and SSEPI DWI were compared between groups.Spearman correlation analysis was performed to explore the relationships of corresponding parameters between SMS-SSEPI DWI and SSEPI DWI.Diagnostic performance of each parameter for distinguishing malignant and benign lesions was evaluated according to the area under the receiver operating characteristic curve(AUC).Results Background noise score of SMS-SSEPI DWI was lower than that of SSEPI DWI(P＜0.05),whereas no significant difference of overall imaging quality,normal anatomical structure depiction,lesion conspicuity,geometric distortion,signal-to-noise ratio(SNR)nor contrast-to-noise ratio(CNR)was found between SMS-SSEPI DWI and SSEPI DWI(all P＞0.05).Parameters derived from SMS-SSEPI DWI were all moderately to highly positively correlated with those from SSEPI DWI(rs=0.66-0.98).Malignant lesions exhibited significantly lower apparent diffusion coefficient(ADC),diffusion coefficient based on FROC(DFROC),fractional order derivative in space(βFROC),diffusion coefficient based on CTRW(DCTRW),temporal diffusion heterogeneity index(αCTRW)and spatial diffusion heterogeneity index(βCTRW)values,but higher spatial parameter(μFROC)value than benign lesions(all P＜0.05).AUC of SMS-SSEPI DWI derived parameters for differentiating malignant from benign lesions were 0.699-0.900,of those from SSEPI DWI were 0.654-0.887,while in both SMS-SSEPI DWI and SSEPI DWI,DFROC had the highest diagnostic efficacy(AUC=0.900,0.887).Conclusion SMS-SSEPI DWI could be used to effectively differentiate malignant and benign breast lesions.

Objective:To investigate the clinical efficacy of stamp skin grafting combined with vacuum sealing drainage in the treatment of diabetic foot ulcers.Methods:A prospective study was conducted involving 80 patients with diabetic foot ulcers admitted to Lishui Central Hospital from January 2020 to December 2022. The patients were divided into an observation group and a control group, with 40 patients in each group, using a random number table method. The control group received treatment with vacuum-sealing drainage technology, while the observation group was treated with stamp skin grafting combined with vacuum sealing drainage. The two groups were compared based on several perioperative indicators, including wound healing time, length of hospital stay, number of dressing changes, and progress of granulation tissue growth. Pain levels were assessed using the Visual Analog Scale. Additionally, dorsalis pedis blood flow dynamics were evaluated, focusing on the diameter of the dorsalis pedis artery and arterial blood flow velocity. Foot function was assessed using the Maryland Foot Function Scale. The occurrence of postoperative complications was recorded.Results:The wound healing time and length of hospital stay in the observation group were (21.54 ± 5.32) days and (27.08 ± 5.97) days, respectively, which were significantly shorter than those in the control group [(26.69 ± 5.66) days, (31.49 ± 6.80) days, t = 4.19, 3.08, both P < 0.05]. The number of dressing changes in the observation group was (5.11 ± 1.14), which was significantly fewer than that in the control group [(8.07 ± 1.59), t = 9.56, P < 0.001]. The progress of granulation tissue growth in the observation group [(3.12 ± 0.64) mm] was faster that in the control group [(2.09 ± 0.48) mm, t = 8.14, P < 0.001]. At 1, 2, and 3 months post-surgery, the Visual Analog Scale scores for the observation group were (3.52 ± 0.65), (2.33 ± 0.42), and (1.40 ± 0.26), respectively, which were significantly lower than those in the control group [(3.96 ± 0.71), (2.74 ± 0.44), (1.78 ± 0.34), t = 2.89, 4.26, 5.615, all P < 0.05). At 3 months post-surgery, the diameter of the dorsalis pedis artery and arterial blood flow velocity in the observation group were (2.64 ± 0.44) mm and (36.42 ± 6.28) cm/s, respectively, which were greater than those in control group [(2.18 ± 0.41) mm, (30.97 ± 5.33) cm/s, t = 4.83, 4.18, both P < 0.001]. At 3 months post-surgery, the scores for pain, foot function, appearance, and range of motion in the observation group were (39.28 ± 6.70), (48.10 ± 7.22), (7.94 ± 1.54), and (12.15 ± 2.35), respectively, which were significantly higher than those in the control group [(33.46 ± 6.89), (43.08 ± 6.68), (5.38 ± 1.06), and (10.69 ± 2.16), t = 3.83, 3.22, 8.66, 2.89, all P < 0.05]. There was no statistically significant difference in the overall incidence of postoperative complications, including skin flap necrosis/dislocation, hematoma accumulation, infection, and ulcer recurrence, between the two groups ( P > 0.05). Conclusions:Stamp skin grafting combined with vacuum sealing drainage can significantly accelerate wound healing in patients with diabetic foot ulcers, reduce postoperative pain, improve dorsalis pedis blood flow dynamics, enhance foot function, and demonstrate good safety.
