Objective:To investigate the staging criteria of renal tuberculosis,and to analyze the diagnostic and therapeutic characteristics as well as prognostic outcomes at different stages.Methods:A retrospective analysis was conducted on the clinical data of 134 patients with renal tuberculosis who were admitted to the Second Hospital of Lanzhou University between January 2019 and December 2023.The study cohort included 62 males and 72 females,with a mean age of(46.63 ± 13.52)years and a mean body mass index(BMI)of(22.85 ± 3.73)kg/m 2. A total of 107 patients resided in rural areas. Sixty patients had a history of pulmonary tuberculosis. Tuberculous lesions were located in the left kidney in 72 cases and in the right kidney in 62 cases. The main presenting complaints included irritative lower urinary tract symptoms in 85 patients and systemic symptoms in 92 patients. Ureteral involvement was observed in 97 patients,bladder involvement in 32 patients,and genital involvement in 9 patients. Based on computed tomography(CT)findings,the number,extent,and degree of renal destruction caused by tuberculous lesions were comprehensively evaluated in axial,coronal,and sagittal planes. The primary staging criteria included lesion diameter(2 cm)and the proportion of renal volume involved by the lesion(one-third,one-half,and two-thirds). Renal tuberculosis was classified into three stages and six subtypes:Stage Ⅰa,a solitary lesion with a diameter ≤ 2 cm;Stage Ⅰb,a solitary lesion >2 cm or multiple lesions confined within one-third of the renal volume;Stage Ⅱa,lesions involving more than one-third but confined within one-half of the renal volume;Stage Ⅱb,lesions involving more than one-half but confined within two-thirds of the renal volume;Stage Ⅲa,lesions involving more than two-thirds of the renal volume with a glomerular filtration rate(GFR)of the affected kidney <10 ml/min;and Stage Ⅲb,complete renal calcification,presenting as an “autonephrectomy”. Among the 134 patients included in this study,7 were classified as Stage Ⅰa,17 as Stage Ⅰb,20 as Stage Ⅱa,19 as Stage Ⅱb,62 as Stage Ⅲa,and 9 as Stage Ⅲb. The severity of hydronephrosis was graded as follows:mild,renal pelvic separation <2 cm;moderate,2-3 cm;and severe,>3 cm. Prior to treatment,the mean renal pelvic separation was(1.76 ± 0.92)cm in Stage Ⅰa,(1.69 ± 0.81)cm in Stage Ⅰb,and(1.10 ± 0.82)cm in Stage Ⅱa,corresponding to mild to moderate hydronephrosis. All 7 patients in Stage Ⅰa underwent ureteroscopic examination and double-J stent placement,combined with a 6-month short-course anti-tuberculosis regimen consisting of isoniazid,rifampicin,pyrazinamide,and ethambutol for 2 months(intensive phase),followed by isoniazid and rifampicin for 4 months(continuation phase). Among the 17 patients in Stage Ⅰb,13 presented with hydronephrosis and underwent ureteroscopic examination and double-J stent placement in combination with 6 months of anti-tuberculosis therapy,while 4 patients with isolated renal tuberculosis received anti-tuberculosis therapy alone for 6 months.Of the 20 patients in Stage Ⅱa,4 with hydronephrosis underwent ureteroscopic examination and double-J stent placement plus 6 months of anti-tuberculosis therapy,whereas 16 underwent nephroureterectomy. All 19 patients in Stage Ⅱb underwent nephroureterectomy. Among the 62 patients in Stage Ⅲa,60 underwent nephroureterectomy,while 2 refused surgery and were treated with the 6-month short-course anti-tuberculosis regimen. Of the 9 patients in Stage Ⅲb,8 underwent nephroureterectomy;in 1 patient,surgery was not performed due to severe adhesions in the operative field,and the patient received the 6-month short-course anti-tuberculosis regimen instead. Follow-up assessments included clinical symptoms,erythrocyte sedimentation rate(ESR),serum creatinine,degree of renal pelvic separation,and imaging findings from urinary tract CT. Efficacy was evaluated according to the following criteria:Cure was defined as clinical stability with all of the following conditions:① improvement of systemic symptoms,including absence of flank pain,fever,and lower urinary tract irritative symptoms,with normalization of erythrocyte sedimentation rate(ESR);② negative urine culture for Mycobacterium tuberculosis;and ③ complete calcification of renal lesions and/or no evidence of tuberculous lesions at other sites. Stable disease was defined as no change in the size or extent of renal tuberculosis lesions. Progressive disease was defined as enlargement or increase in the number of tuberculous lesions or involvement of additional sites. Results:Among the 7 patients in Stage Ⅰa,follow-up imaging after treatment showed a mean renal pelvic separation of(0.44 ± 0.56)cm,which was significantly reduced compared with baseline( t = 3.909, P = 0.008). Five patients achieved cure,1 remained stable,and 1 showed disease progression and subsequently underwent nephroureterectomy,resulting in postoperative cure. In Stage Ⅰb,among 13 patients with hydronephrosis,post-treatment imaging showed a mean renal pelvic separation of(0.8 ± 0.75)cm,a statistically significant improvement from baseline( t = 5.633, P < 0.01). Six patients were cured,4 remained stable,and 3 experienced disease progression and underwent nephroureterectomy. Of the 4 patients with isolated renal tuberculosis,2 were controlled,and 2 progressed and underwent nephroureterectomy. In Stage Ⅱa,among 4 patients with tuberculous hydronephrosis,post-treatment renal pelvic separation was(1.20±0.98)cm,with no significant difference from baseline( t = -1.675, P = 0.193);these patients underwent nephroureterectomy 1-2 years later. The remaining 16 patients without hydronephrosis underwent nephroureterectomy and were cured. All 19 patients in Stage Ⅱb underwent nephroureterectomy;17 were cured,and 2 developed ipsilateral perirenal fluid collections 3 months postoperatively,which resolved spontaneously with the standard 6-month anti-tuberculosis regimen. Among 62 patients in Stage Ⅲa,60 underwent nephroureterectomy. Of these,54 were cured;1 developed a urinary tract infection within 2 weeks postoperatively;3 showed contralateral renal disease progression at 3 months;and 1 developed ipsilateral perirenal fluid at 3 months,which resolved spontaneously with standard anti-tuberculosis therapy. One patient developed solitary kidney failure 7 months postoperatively and underwent ureteral stent placement,with disease remaining stable thereafter. Two patients refused surgery and received only anti-tuberculosis therapy;during follow-up,1 patient experienced disease progression and died of disseminated tuberculosis after 1 year,while the other developed contralateral renal involvement at 3 months and received standard 6-month therapy,with disease remaining stable. Among 9 patients in Stage Ⅲb,8 underwent nephroureterectomy and were cured. One patient,with severe adhesions precluding surgery,received anti-tuberculosis therapy alone,and disease remained stable over a 2-year follow-up. Conclusions:The CT-based staging system for renal tuberculosis proposed in this study(three stages and six subtypes)effectively reflects the severity of renal lesions and clearly delineates the clinical characteristics and prognostic outcomes at each stage. Stage Ⅰ patients treated with anti-tuberculosis drugs combined with double-J stent placement demonstrated favorable outcomes and high renal preservation rates. In contrast,Stages Ⅱ and Ⅲ patients showed poor responses to anti-tuberculosis therapy combined with drainage,with a higher risk of disease progression and relatively worse prognosis,highlighting the recommendation for early nephroureterectomy of the affected kidney.

Objective:To identify the latent profiles of kinesiophobia in elderly patients with chronic obstructive pulmonary disease (COPD) and explore associated influencing factors.Methods:Elderly COPD patients were selected using a convenience sampling method from the respiratory departments of three Grade A tertiary hospitals in Anhui Province between July 2023 and January 2024. Data were collected using a general demographic questionnaire, the Tampa Scale of Kinesiophobia (TSK), and the Physical Activity Rating Scale (PARS-3). Latent profile analysis was performed using Mplus 8.3, and multinomial Logistic regression was applied to identify influencing factors associated with different latent classes.Results:A total of 348 questionnaires were distributed, and 330 valid responses were obtained, with a valid response rate of 94.83%. The mean TSK score of the 330 patients was (44.53±6.60). Kinesiophobia in elderly COPD patients could be classified into three latent categories: high kinesiophobia-low perceived exercise benefit (25.8%, 85/330), moderate kinesiophobia-low perceived exercise risk (40.9%, 135/330), and low kinesiophobia-high perceived exercise benefit (33.3%, 110/330). Multinomial Logistic regression analysis showed that physical activity level, educational background, body mass index, disease severity, and employment status were the influencing factors of kinesiophobia classification (all P<0.05) . Conclusions:Kinesiophobia in elderly COPD patients presents with distinct classification characteristics. Healthcare providers should develop and implement targeted interventions based on the identified profiles and their influencing factors to help patients reduce their fear of physical activity.

With the development of modern sequencing techniques and bioinformatics, genomes that were once thought to be noncoding have been found to encode abundant functional micropeptides (miPs), a kind of small polypeptides. Although miPs are difficult to analyze and identify, a number of studies have begun to focus on them. More and more miPs have been revealed as essential for energy metabolism homeostasis, immune regulation, and tumor growth and development. Many reports have shown that miPs are especially essential for regulating glucose and lipid metabolism and regulating mitochondrial function. MiPs are also involved in the progression of related diseases. This paper reviews the sources and identification of miPs, as well as the functional significance of miPs for metabolism-related diseases, with the aim of revealing their potential clinical applications.

The syndrome of dampness stagnancy due to spleen deficiency (DSSD) is relatively common globally. Although the pathogenesis of DSSD remains unclear, evidence has suggested that the gut microbiota might play a significant role. Radix Astragali, used as both medicine and food, exerts the effects of tonifying spleen and qi. Astragalus polysaccharide (APS) comprises a macromolecule substance extracted from the dried root of Radix Astragali, which has many pharmacological functions. However, whether APS mitigates the immune disorders underlying the DSSD syndrome via regulating gut microbiota and the relevant mechanism remains unknown. Here, we used DSSD rats induced by high-fat and low-protein (HFLP) diet plus exhaustive swimming, and found that APS of moderate molecular weight increased the body weight gain and immune organ indexes, decreased the levels of interleukin-1β (IL-1β), IL-6, and endotoxin, and suppressed the Toll-like receptor 4/nuclear factor-κB (TLR4/NF-κB) pathway. Moreover, a total of 27 critical genera were significantly enriched according to the linear discriminant analysis effect size (LEfSe). APS increased the diversity of the gut microbiota and changed its composition, such as reducing the relative abundance of Pseudoflavonifractor and Paraprevotella, and increasing that of Parasutterella, Parabacteroides, Clostridium XIVb, Oscillibacter, Butyricicoccus, and Dorea. APS also elevated the contents of short-chain fatty acids (SCFAs). Furthermore, the correlation analysis indicated that 12 critical bacteria were related to the body weight gain and immune organ indexes. In general, our study demonstrated that APS ameliorated the immune disorders in DSSD rats via modulating their gut microbiota, especially for some bacteria involving immune and inflammatory response and SCFA production, as well as the TLR4/NF-κB pathway. This study provides an insight into the function of APS as a unique potential prebiotic through exerting systemic activities in treating DSSD.

Objective:To understand the potential categories of self-efficacy in stress injury management of nurses in operating room and analyze the characteristics of different categories of nurses.Methods:A cross-sectional survey was conducted from June to August 2022. A total of 469 operating room nurses from 12 Grade A hospitals in Guangxi, Sichuan, Guizhou, Yunnan, Shanxi, Xinjiang and Chongqing were selected by convenient sampling method as subjects. General data questionnaire, proactive personality Inventory, Caring behavior Inventory, transformational leadership inventory, nursing clinical Decision scale and nurses stress injury management self-efficacy scale were used to investigate. Potential profile was used to analyze nurses' self-efficacy in stress injury management, and multiple Logistic regression was used to analyze different potential factors.Results:The self-efficacy of nurses in the management of stress injury in operating room could be divided into three potential profiles: poor self-efficacy group (23.9%, 112/469), medium self-efficacy group (33.0%, 155/469) and good self-efficacy group (43.1%, 202/469). Proactive personality, caring behavior, transformational leadership, nursing clinical decision-making and educational background were the factors influencing self-efficacy of operating room nurses in stress injury management (all P<0.05). Conclusions:There are three potential profiles of self-efficacy in the management of stress injury in operating room nurses. Nursing managers can give targeted intervention strategies according to different characteristics of nurses to improve their self-efficacy.
