OBJECTIVE To investigate the effects and mechanism of the Yishen paidu formula on renal fibrosis in rats with chronic renal failure （CRF） through the reactive oxygen species （ROS）/thioredoxin-interacting protein （TXNIP）/NOD-like receptor thermal protein domain associated protein 3 （NLRP3） pathway. METHODS Rats were randomly divided into control group， model group， Yishen paidu formula low-dose （Yishen paidu formula-L） group， Yishen paidu formula high-dose （Yishen paidu formula- H） group， Yishen paidu formula-H+pcDNA-NC group， and Yishen paidu formula-H+ pcDNA-TXNIP group， with 10 rats in each group. Except for control group， all other rats were fed a diet containing 0.5% adenine to establish a CRF model； the rats were then administered corresponding drugs or normal saline intragastrically or via tail vein， once daily， for 8 consecutive weeks. After the last administration， the levels of serum creatinine （Scr）， blood urea nitrogen （BUN）， ROS， superoxide dismutase （SOD）， malondialdehyde （MDA）， tumor necrosis factor-α （TNF-α）， interleukin （IL）-6， and IL-1β were measured in each group. Pathological changes in renal tissue were observed， and the protein expression levels of Collagen Ⅲ， α-smooth muscle actin （α-SMA）， transforming growth factor-β1 （TGF-β1）， TXNIP and NLRP3 in renal tissue were detected. RESULTS Compared with model group， the renal histopathological damage and fibrosis of rats in Yishen paidu formula-L group and Yishen paidu formula-H group were significantly alleviated. The levels of Scr， BUN， ROS， MDA， TNF- α， IL-6 and IL-1β， and the protein expressions of Collagen Ⅲ， α-SMA， TGF-β1， TXNIP and NLRP3 were significantly decreased， while SOD levels were significantly increased （P＜0.05）. Moreover， the changes were more pronounced in the Yishen paidu formula-H group （P＜0.05）. Compared with Yishen paidu formula-H+pcDNA-NC group， above indexes of rats in Yishen paidu formula-H+pcDNA-TXNIP group were reversed significantly （P＜0.05）. CONCLUSIONS Yishen paidu formula can inhibit renal fibrosis in CRF rats by suppressing the ROS/TXNIP/NLRP3 pathway.

Objective: To investigate the relationship between physical development indicators and the onset and progression of myopia among children and adolescents, so as to provide theoretical support for coordinated vision and physical health management. Methods: A prospective cohort study was conducted. In September 2022, 3 102 students from grade one in primary school to grade three in junior high school (five year primary school and four year junior high school) from six schools in Huantai County, Shandong Province, were selected using multistage cluster random sampling method to participate in an epidemiological survey on myopia, with follow up completed in September 2023. Follow up value minus baseline value( d ) was used to assess changes in physical development and vision indicators. Multivariate Logistic regression analysis was used to examine the relationship between physical development indicators and the incidence of myopia. Generalized linear models were established to analyze the relationship between physical development indicators and changes in d spherical equivalent (SE) and d axial length (AL) . Results: Multivariate Logistic regression analysis showed that, after adjusting for factors such as gender, age, and baseline body mass index, the third ( Q 3)and fourth ( Q 4)quartiles of d height showed increased risks of myopia onset within one year compared to the first quartile( Q 1) ( OR =1.85,95% CI =1.18-2.88; OR =1.74,95% CI =1.09-2.78,both P ＜0.05). Results from the generalized linear model indicated that, after adjusting for confounding factors such as gender, age, and baseline SE, d SE was negatively correlated with d height and d weight in children and adolescents ( β =-0.024, 95% CI =-0.031 to -0.018; β =-0.006, 95% CI =-0.011 to -0.001), d AL was positively correlated with d height and d weight in children and adolescents ( β =0.011, 95% CI =0.008-0.013; β =0.005, 95% CI =0.003-0.007) (all P ＜0.05). Conclusions Physical development indicators in children and adolescents were associated with the onset and progression of myopia. Dynamic monitoring and early intervention of myopia should be strengthened for children and adolescents with rapid height and weight gain to achieve coordinated management of myopia and physical development.

Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

Objective:Treat-to-target strategies for psoriatic arthritis (PsA) have been proposed for several years, however, the status of target and goal achievement in China is unknown. Therefore, we aimed to investigate the target achievement of PsA patients, and differences of treatment goals were further analyzed.Methods:A total of 360 PsA patients from Peking University First Hospital PsA patient cohort (PKUPsA) between January 2016 and March 2024 were included. We retrospectively analyzed the disease activity of patients at their enrollment. Minimal disease activity (MDA), disease activity index for PsA (DAPSA), clinical DAPSA (cDAPSA) and disease activity score based on 28 joint counts (DAS28) were evaluated. Interclass correlation coefficient (ICC) was used to test the consistency of all these assessments.Results:Three hundred and sixty patients were included in this study, with 149 females (41.4%), median age 47 (36, 57) years and duration of PsA for 2.0(1.0, 6.8) years. 129 (35.8%) patients reported family history of PsO. The most common comorbidities were hyperlipidemia (101, 28.1%) and hypertension (78, 21.7%). There were 217 (60.3%), 75 (20.8%) and 18 (5.0%) patients treated with conventional synthetic DMARDs, biologics and JAK inhibitors respectively. Forty-nine (13.6%) patients ever received intra-articular injection of glucocorticoid. Based on the different definitions, the rates of target achievement were 33.9% (MDA), 56.1% (DAPSA), 60.8% (DAS28-ESR), 63.9% (DAS28-CRP) and 64.2% (cDAPSA). The main limiting factors for MDA attainment among those who had achieved DAPSA or DAS-defined targets were pain VAS, Psoriasis Area and Severity Index (PASI), tender/swollen joint count, patient global assessment, HAQ, and number of enthesitis, based on leeds Enthesitis Index(LEI). The ICCs of these evaluation methods were 0.489~0.819 ( P<0.001). The consistency was the best between DAPSA and cDAPSA, medium between DAS28-CRP and DAS28-ESR, and worst between MDA and DAS28-CRP. Moreover, DAPSA was more consistent with DAS28 than cDASPA. MDA showed moderate consistency with all other assessments. Conclusion:33.9%~64.2% of PsA patients achieved targets based on different definitions. MDA was the most stringent target, while cDAPSA was the most loose one. In general, MDA was not well consistent with other assessments.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the role of evidence-based clinical guidelines combined with "rain classroom" smart teaching in standardized residency training in endocrinology department.Methods:The 100 trainees who underwent standardized residency training in the Department of Endocrinology at Xiamen Hospital from September 2022 to September 2023 were selected as the research subjects. They were divided into groups based on the parity of their admission batches, with even-numbered batches assigned to the control group and odd-numbered batches to the experimental group, with 50 trainees in each group. The control group received traditional teaching, while the experimental group was taught using evidence-based clinical guidelines combined with "rain classroom" smart teaching. Statistical comparisons were made between the two groups in terms of exit examination scores, teaching effectiveness, teaching satisfaction, and evaluation of trainees by teachers. SPSS 22.0 was used for t test and Chi-square test. Results:The experimental group demonstrated significantly higher scores in theoretical knowledge [(25.62±3.12) vs. (22.71±3.27)], case analysis [(25.18±3.24) vs. (22.24±3.35)], clinical operation [(25.01±3.19) vs. (22.12±3.29)], and daily performance [(8.12±1.01) vs. (7.21±1.13)] compared to the control group in exit examination ( P<0.001). Additionally, the experimental group showed superior performance in self-learning [(8.57±1.12) vs. (7.64±1.24)], clinical thinking [(8.61±1.16) vs. (7.78±1.28)], evidence-based thinking [(8.52±1.13) vs. (7.69±1.26)], clinical skills [(8.49±1.17) vs. (7.61±1.23)], communication skills [(8.53±1.18) vs. (7.67±1.29)], and literature review [(8.59±1.15) vs. (7.71±1.27)], with statistically significant differences ( P<0.05). Teaching satisfaction in the experimental group (96.00%) was significantly higher than that in the control group (82.00%) ( P=0.025). The pass rates rated by teachers were higher in the experimental group in medical history collection (94.00% vs. 80.00%), physical examination (96.00% vs. 82.00%), clinical thinking (92.00% vs. 76.00%), communication skills (94.00% vs. 80.00%), literature review (96.00% vs. 84.00%), specialized skills (94.00% vs. 78.00%), and diagnosis and treatment plan formulation (92.00% vs. 74.00%), with statistically significant differences ( P<0.05). Conclusions:The implementation of evidence-based clinical guidelines combined with "rain classroom" smart teaching in the standardized residency training in endocrinology department can significantly improve the exit examination scores and teaching satisfaction of trainees, teaching effectiveness, and evaluation of trainees by teachers. This teaching method has a positive role in improving the clinical comprehensive ability of trainees such as evidence-based medical thinking and standardized clinical diagnosis and treatment.
