Objective To analyze the epidemiologic burden of colorectal cancer in Xishan District, Kunming City, Yunnan Province from 2018 to 2020. Methods Indicators of epidemiologic burden were calculated, including incidence rate, mortality rate, age-specific incidence/mortality rates, potential years of life lost (PYLL), and disability-adjusted life years (DALY) based on the National Disease Control and Prevention Center’s "Cancer Information Registration and Reporting System" and "Cause of Death Registration System". Results From 2018 to 2020, the ASR (China) for the incidence of colorectal cancer in Xishan District, Kunming City increased from 25.27/10⁵ to 26.29/10⁵, while the ASR (China) for mortality decreased from 17.11/10⁵ to 16.03/10⁵. The PYLL in 2018–2020 were 1399.63, 1376.78, and 1571.56 person-years, respectively, whereas the DALY in 2018–2020 were 1927.74, 1875.05, and 1945.17 person-years, respectively. The morbidity, mortality, PYLL, and DALY were generally higher in males than in females over 45 years of age. Conclusion Given the parallel trends of persistent incidence risk and steadily declining mortality for colorectal cancer in Xishan District, Kunming City, a three-tier prevention and control system centered on "lifestyle intervention–regular screening–positive case tracking" should be established, with a focus on covering high-risk populations, particularly males over 45 years of age.

Focusing on the ethical dilemmas encountered in implementing the child-friendly concept within the context of limited medical assistance resources， this study constructed an integrative analytical framework combining “child-friendly medical principles and social work ethics.” Taking E Hospital in Shanghai as a case study， this paper employed qualitative methods such as participatory observation and semi-structured interviews to explore the ethical practices of medical social workers in charitable medical assistance. It was found that medical social workers engaged in ethical practices across three dimensions. In resource allocation， they achieved distributive justice through dynamic assessment and de-labeling， thereby bridging structural disparities. Regarding service delivery， they leveraged integrated services and information platforms to promote the transformation of assistance from purely economic compensation toward the “whole-person development.” In terms of child participation， they adopted a “relationship-based” progressive strategy to gradually empower children’s expression and decision-making within the local family cultural context. This study provided an empirical reference for understanding the ethical practices of child-friendly charitable medicine in the local context.

To investigate the feasibility and advantages of "Axis Coordinate Localization Method" combined with total endoscopic technique for parotid surgery. A total of 31 patients with parotid gland tumors who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2022 to August 2024 were included in this study. The cohort comprised 11 males and 20 females, with age of (38.9±13.9) years and a maximum tumor diameter of (19.34±6.89) mm. Among these cases, 93.5% (29/31) involved the superficial lobe and 6.5%(2/31) the deep lobe of the parotid gland. The "axial" localization method was utilized to plan the surgical approach: establishing a coordinate system with the earlobe as the origin, the surface projection of the parotid duct as the x-axis, and a perpendicular line through the origin as the y-axis. The incision type-pre-tragal, retroauricular groove, or postauricular hairline-was selected according to the position of the tumor′s surface projection center within this coordinate system. All operations were performed using a complete endoscopic technique for tumor and glandular tissue resection. Postoperative facial nerve function was assessed with the House-Brackmann grading scale, while patient incision satisfaction, impact on work and daily life, and facial symmetry were quantitatively evaluated using a Numerical Rating Scale (10-point system).　All 31 patients successfully underwent the procedure. Short-term postoperative complications included temporary facial paralysis in 1 case (3.2%), periauricular numbness in 1 case (3.2%), surgical site effusion in 1 case (3.2%), and subcutaneous hematoma in 1 case (3.2%). All complications resolved after appropriate management. During follow-up, there were no instances of sialocele, Frey syndrome, incision infection, or tumor recurrence. Patient ratings were as follows: incision satisfaction (9.42±0.78), impact of surgery on daily life (1.32±0.60), and facial symmetry (9.29±0.78). The one case of temporary facial paralysis recovered 3 months after surgery. The combination of the "Axial" localization method and fully endoscopic technique demonstrates clear clinical feasibility in parotid tumor resection. This approach enables rapid and personalized incision selection based on tumor location, while the endoscopic minimally invasive technique reduces tissue trauma, improves cosmetic outcomes, and enhances surgical safety. It provides a new minimally invasive treatment pathway for patients with benign parotid tumors.

Objective:To evaluate the clinical equivalence between a domestic calcipotriol/betamethasone dipropionate ointment and the originator product in the treatment of stable plaque psoriasis.Methods:A multicenter, randomized, double-blind, three-arm, parallel-group, active- and placebo-controlled study was conducted, and 449 patients aged 18 - 65 years with stable plaque psoriasis were enrolled from 25 hospitals (such as the First Affiliated Hospital of China Medical University). Eligible patients had a baseline physician's global assessment (PGA) score of ≥ 3 points, baseline body surface area (BSA) involvement of 5% - 30%, and a target lesion psoriasis area and severity index (TL-PASI) for plaque elevation of ≥ 3 points. Participants were randomly assigned in a 2:2:1 ratio to the test group ( n = 179), reference group ( n = 180), and placebo group ( n = 90), and applied the domestic calcipotriol/betamethasone dipropionate ointment, originator product, and ointment base respectively, once daily in the evening for 4 weeks. Efficacy and safety were assessed at weeks 1, 2, and 4. The primary efficacy endpoints were the treatment success rates and clinical success rates in each group at week 4. The per-protocol set (PPS) was used for the primary efficacy analysis, and the intention-to-treat (ITT) set for supplementary efficacy analysis. Equivalence between the test and reference preparations was tested using the Cochran-Mantel-Haenszel method adjusted for randomization strata. Superiority of the test and reference preparations over the placebo was also tested. Measurement data were compared among the 3 groups using analysis of variance or non-parametric tests, while treatment success rates, clinical success rates, and incidence rates of adverse reactions were compared using the chi-square test. Results:The ITT, PPS, and safety sets included 447, 420, and 448 patients, respectively. In the ITT set, patients were aged 43.6 ± 12.8 years, including 320 (71.6%) males and 127 (28.4%) females, and the disease duration was 11.21 ± 9.05 years; 316 (70.7%) had a PGA score of 3 points and 131 (29.3%) had a PGA score of 4 - 5 points. No significant differences in the baseline characteristics (including age, sex, disease duration and disease severity) were observed among the 3 groups (all P > 0.05). Based on the PPS analysis, the treatment success rates were 57.9% (99/171) in the test group, 50.3% (86/171) in the reference group, and 7.7% (6/78) in the placebo group, and the clinical success rates were 57.9% (99/171), 50.3% (86/171), and 10.3% (8/78), respectively; both the test and reference groups were superior to the placebo group in both treatment and clinical success rates (all P < 0.001) ; the rate differences for treatment success (90% confidence interval [ CI]: -1.3% - 16.4%) and clinical success (90% CI: -1.3% - 16.3%) between the test and reference groups were entirely within the pre-defined equivalence margin (-20% - 20%). Subgroup analyses by baseline PGA scores: for patients with a baseline PGA score of 3 points, the treatment success rates in the test, reference, and placebo groups were 60.8% (73/120), 52.1% (62/119), and 11.1% (6/54), respectively, and the corresponding clinical success rates were 61.7% (74/120), 53.8% (64/119), and 13% (7/54), respectively; the test and reference groups did not differ significantly in treatment or clinical success rates (both P > 0.05), but both showed higher success rates than the placebo group (all P < 0.001) ; the results of statistical comparisons among the 3 groups in patients with a baseline PGA score of 4 - 5 points were consistent with those observed in patients with a baseline PGA score of 3 points. The percentage reductions in PGA and TL-PASI scores from baseline to weeks 1, 2, and 4 showed significant differences among the 3 groups, which were significantly higher in the test and reference groups than in the placebo group (all P < 0.001), but did not differ between the test and reference groups (all P > 0.05). The primary adverse reactions were local skin reactions, such as pruritus, pain, and erythema. The incidence rates of adverse reactions were 8.9% (16/179) in the test group, 7.3% (13/179) in the reference group, and 7.8% (7/90) in the placebo group, with no significant difference among the 3 groups ( P > 0.05) . Conclusions:The domestic calcipotriol/betamethasone dipropionate ointment demonstrated clinical equivalence to the originator product in the treatment of stable plaque psoriasis, and the two agents exhibited comparable efficacy for patients with varying degrees of disease severity, and were comparable in the speed and degree of clinical improvement, with similar favorable safety profiles.

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 clinical and genetic characteristics of developmental and epileptic encephalopathy related to the EEF1A2 gene. Methods:The clinical data and whole exome sequencing results of 2 patients who were diagnosed as developmental and epileptic encephalopathy related to the EEF1A2 gene in the Children′s Hospital, Capital Institute of Pediatrics in June 2016 and August 2018 were retrospectively analyzed. Relevant literatures were retrieved using " EEF1A2" and "epileptic encephalopathy" or "epilepsy" as key words in Online Mendelian Inheritance in Man, PubMed, CNKI and Wanfang databases (literatures searching from establishment of these databases to June 2024). The clinical and genetic characteristics of developmental and epileptic encephalopathy related to the EEF1A2 gene were summarized based on literature reports and the data of these 2 patients. Results:Patient 1 was a 9 months old male infant. He presented with global developmental delay. He developed myoclonic seizures at 4 months old. Valproic acid, clonazepam, topiramate and vagus nerve stimulation were all ineffective. Both of his hands had transverse palmar crease. The de novo c.364G>A variant in the EEF1A2 gene (NM_001958.3) was identified and he was diagnosed with developmental and epileptic encephalopathy related to the EEF1A2 gene. Patient 2 was a 2 years and 2 months old boy. He presented with global developmental delay. Myoclonic seizures occurred when he was 2 years and 3 months old, and various anti-epileptic drugs were ineffective. He had left eye esotropia and low muscle tone in the extremities. He died at the age of 4. The de novo c.208G>A variant in the EEF1A2 gene (NM_001958.3) was identified and he was diagnosed with developmental and epileptic encephalopathy related to the EEF1A2 gene. Eight literatures on developmental and epileptic encephalopathy related to the EEF1A2 gene (all in English) were retrieved, reporting 28 cases (totally 30 patients, including 2 cases in this study). The main clinical manifestations were psychomotor developmental delay (30/30, 100.0%), facial dysmorphism (15/30, 50.0%), refractory epilepsy (14/26, 53.8%), myoclonic seizures (19/26, 73.1%), and movement disorders (8/16). A total of 15 mutation sites in the EEF1A2 gene were reported, all of which were missense mutations. Conclusions:Developmental and epileptic encephalopathy related to the EEF1A2 gene is primarily characterized by delayed psychomotor development, distinctive facial features, drug-resistant epilepsy, myoclonic seizures, and movement disorders. Variants in the EEF1A2 gene are predominantly missense mutations, and identifying these variants plays a crucial role in accurate diagnosis of the disease.

Colony-stimulating factor-1 receptor (CSF1R)-related leukoencephalopathy (CSF1R-L) is a rare autosomal dominant neurodegenerative disorder caused by mutations in the CSF1R gene. It is typically characterized by rapidly progressive cognitive decline, motor dysfunction, and psychiatric or behavioral abnormalities, leading to significant disability and early mortality. More than 100 mutations of CSF1R have been identified in CSF1R-L, but the clinical-genotype relationship is unclear. This report describes a case of CSF1R-L that initially presented with atypical symptoms of left lower limb pain, numbness, and weakness. Despite the non-specific presentation, comprehensive imaging data were available throughout the disease course. Genetic testing identified a heterozygous missense mutation in exon 18 of the CSF1R gene (c.2508CA, p.Ser836Arg), a novel variant not previously reported in the literature. This case offers valuable insights into the dynamic progression of cranial MRI changes in CSF1R-L, broadens the genetic spectrum of this disease, enhances awareness among clinicians, and provides crucial information for the early diagnosis of this condition.

Objective:To evaluate the changes of carotid intima thickness（CIT）and stiffness parameters in ankylosing spondylitis（AS）patients by 24 MHz ultra-high frequency ultrasound probe and RF-data based quantitative analysis on vessel stiffness（R-VQS），and to explore its influencing factors.Methods:Sixty patients with AS who underwent consultation at Henan Provincial People's Hospital from November 2023 to May 2024 were prospectively collected as AS group，54 healthy volunteers matched for sex，age，and body mass index were collected as control group. CIT were measured using a 24 MHz ultra-high frequency ultrasound probe，hardness coefficien（HC）and pulse wave velocity（PWV）were measured by R-VQS，the differences of the parameters between the two groups were compared. The changes of carotid artery elasticity and intima thickness and their influencing factors in patients with AS were explored by univariate and multivariate linear regression analysis.Results:①C-reactiveprotein，erythrocyte sedimentation rate（ESR），neutrophil count and neutrophil to lymphocyte ratio（NLR）were elevated in the AS group compared with the control group，and the differences were statistically significant（all P < 0.05）. ②CIT，carotid intima-media thickness（CIMT），HC，PWV and epicardial adipose tissue thickness（EATT）were all increased in the AS group compared with the control group，and the differences were statistically significant（all P < 0.05）. ③Multifactorial linear regression analysis showed that EATT，ESR were the main influencing factors of HC，PWV and CIT（ β=2.192，0.031；1.792，0.002；0.097，0.001；all P＜0.05）. Conclusions:Carotid CIT，CIMT，HC，PWV and EATT are all higher in the AS patients，and ESR and EATT are the main influencing factors of HC，PWV，and CIT，suggesting that more attention should be paid to the detection of ESR and EATT in patients with AS when interventions are performed clinically.

Ulcerative colitis(UC)is a common chronic non-specific intestinal inflammatory disease clinically.Its pathogenesis is complex,prolonged the disease course,and it is frequent clinical recurrence.In recent years,the incidence of UC has shown an upward trend and tends to younger onset,which seriously affects the quality of life of patients and increases the social medical burden.Mitogen-activated protein kinase(MAPK)plays an important role in the occurrence and development of UC,participating in inflammatory response,oxidative stress,autophagy,apoptosis,pyroptosis,and intestinal barrier.MAPK may be a new target for the treatment of UC.Traditional Chinese medicine has a long history and remarkable curative effect in treating UC,with the advantages of multiple pathways,multiple targets,and multiple components.In recent years,many studies have shown that single Chinese herbal medicines and compound prescriptions can mediate MAPK signaling pathway to inhibit inflammatory response and oxidative stress,regulate autophagy,inhibit apoptosis and pyroptosis,repair the intestinal barrier,and treat UC in many aspects.This article reviews the MAPK signaling pathway,the mechanism by which the MAPK signaling pathway regulates UC,and the research progress of traditional Chinese medicine in treating UC based on the MAPK signaling pathway,hoping to provide theoretical support for the treatment of UC by traditional Chinese medicine and new ideas and references for the research of related new drugs.

OBJECTIVES: This study aims to investigate the optimal dose ratio and mechanisms of the primary active components in Yinchenhao decoction (geniposide, chlorogenic acid, and rhubarb polysaccharides) for ameliorating metabolic-associated steatotic liver disease (MASLD). METHODS: C57BL/6 mice were randomly divided into the normal control group, model control group, uniform design groups 1-6, and Yinchenhao Decoction group; except for the normal control group, mice in all other groups were fed a Western diet to establish a MASLD model, and after 8 weeks of modeling, mice in the uniform design groups 1-6 and Yinchenhao Decoction group were given the corresponding drugs by gavage. At 12 weeks, all mice were sacrificed: their body weight and liver weight were measured, hematoxylin-eosin staining was used to observe the histopathological changes of liver tissue, the plasma levels of alanine transaminase (ALT) and aspartate transaminase (AST) were detected, and the levels of total cholesterol (TC) and triglycerides (TG) in plasma and liver were measured. Based on these results, the optimal uniform design group was identified; subsequently, with plasma AST, plasma TG, and liver TC levels as screening indicators, the optimal dose ratio was obtained via a regression equation, which was further verified from two dimensions, namely functional indicators and tissue morphology. Meanwhile, glucose tolerance test and insulin tolerance test were conducted to evaluate glucose metabolic homeostasis and insulin sensitivity in mice, periodic acid-Schiff staining was used to observe glycogen accumulation, quantitative reverse transcription-polymerase chain reaction was employed to detect the mRNA expression of genes related to glycolipid metabolism and bile acid metabolism, Western blotting was performed to measure the protein expression of molecules involved in bile acid metabolism, and commercial kits were used to determine the plasma levels of total bilirubin (TBIL), direct bilirubin (DBIL), and total bile acid (TBA). RESULTS: Combinations of geniposide, chlorogenic acid, and rhubarb polysaccharide all reduced the liver-to-body weight ratio, alleviated liver injury, and decreased lipid accumulation, among which the uniform design group 6 (200 mg/kg geniposide+160 mg/kg chlorogenic acid+340 mg/kg rhubarb polysaccharide) exhibited the optimal efficacy. Meanwhile, regression analysis indicated that the dosage ratio of uniform design group 6 was the optimal one for MASLD intervention. Validation experiments showed that, compared with single-drug intervention, the optimal dosage ratio resulted in significantly lower body weight, as well as lower plasma levels of ALT, AST and TC in mice (all P<0.05), along with a more pronounced reduction in the area of hepatic lipid accumulation. Mechanistic investigation experiments demonstrated that intervention with the optimal dosage ratio significantly improved glucose tolerance and insulin sensitivity in mice (all P<0.05), reduced hepatic glycogen deposition, and downregulated the mRNA expression of glycolipid metabolism-related genes such as Gsk3, G6pc, Pck1, Fbp1, Fasn, Srebp-1c, Scd1, Slc27a2, and Slc27a5 (all P<0.05); it also decreased plasma levels of TBIL, DBIL, and TBA (all P<0.05), reversed the abnormal protein expression of bile salt export pump (BSEP), farnesoid X receptor (FXR), and cholesterol-7α-hydroxylase (CYP7A1) in the liver (all P<0.05), and reversed the abnormal mRNA expression of bile acid metabolism-related genes including Nr1h4, Cyp7a1, Cyp27a1, Slc10a1, and Slco1a1 (all P<0.05). CONCLUSIONS The combination of geniposide (200 mg/kg), chlorogenic acid (160 mg/kg), and rhubarb polysaccharide (340 mg/kg) exerts the optimal ameliorative effect on MASLD in mice. This superior efficacy is presumably achieved by synergistically regulating the key nodes of glycolipid metabolism and bile acid metabolism, ultimately optimizing the therapeutic outcome.
