Diabetic foot (DF) is one of the most serious chronic complications of diabetes. The incidence rate among global diabetes patients is as high as 15% to 25%, and about 50% of patients will develop contralateral foot ulcers within 5 years after the first unilateral ulcer. As a non-invasive prevention and control solution, the application progress of functional insoles is mainly reflected in the following aspects:(1) Material innovation. The application of new composite materials and smart materials has significantly enhanced the pressure reduction effect and comfort. (2) Structural optimization. The development of multi-layer design and local pressure reduction structure has achieved more precise pressure distribution regulation. (3) Manufacturing process. 3D printing and parametric design have enabled the personalized customization of functional insoles. (4) Intelligent monitoring. It integrates functions such as pressure sensing and temperature monitoring, achieving real-time monitoring and early warning of foot conditions. Clinical research has confirmed that personalized functional insoles could reduce the incidence of foot ulcers and shorten the healing time of ulcers. At present, the research hotspots mainly focus on the development of smart materials, the construction of multi-functional integration and remote monitoring systems. However, in-depth research is still needed in the aspects of biomechanical mechanisms, standardized evaluation systems and long-term efficacy assessment. The development of future functional insoles should focus on the coordinated advancement of "personalization-intelligence-standardization", with the aim of providing more effective solutions for the prevention and treatment of DF.

Objective:To establish a method for obtaining planning target volume (PTV) and planning risk volume (PRV) margins caused by rotation in the use of adapt-to-position (ATP) modality of magnetic resonance linear accelerator (MRL) for patients with intracranial tumors.Methods:Clinical data of 6 patients with intracranial tumors (150 fractions in total) who received MRI-guided online ATP radiotherapy in Peking Union Medical College Hospital from November 2023 to January 2024 were retrospectively analyzed. The pre-planned CT structure was copied onto each segmented MR image and then the structures were traced back to the CT image according to the three-dimensional registration relationship. The anisotropic distance of the structure based on the original CT structure was calculated to obtain the variation range of the target and the organs at risk. The maximum anisotropic value was taken as the result of the PTV and the relationship between the results and intracranial location of different patients was analyzed. Group comparison was performed by Chi-square test. Two group comparison was conducted by post-hoc Wilcoxon signed-rank test. Results:After the rotation deviation was included, the range of target changes in the six directions of left and right (L/R), anterior and posterior (A/P) and superior and inferior (S/I) of the 6 patients were: (1.24± 0.86) mm/(1.91± 1.07) mm, (2.02± 1.26) mm/(1.66± 1.07) mm, (1.84± 1.84) mm /(2.94±1.93) mm, respectively. The results in the SI direction were significantly different, and the values in the I direction in 2 patients exceeded 4 mm, the margins suitable for all patients were 3.01 mm/2.4 mm(A/P), 1.9 mm/2.93 mm(L/R) and 3.14 mm/4.62 mm(S/I) in different directions, respectively. The L/R direction of the lens and the S/I direction of the optic nerve were significantly changed, and the A/P direction of the brain stem was (3.99± 4.64) mm. Larger values might be required when the target was in the posterior brain (left-down area, right-down area).Conclusions:The rotation deviation, organ movement and intracranial location affect the PTV and the organs at risk PRV in the MRI-guided ATP modality in intracranial tumors patients. The margin generation method based on image fusion can help to quantify the margin value reasonably.

BACKGROUND:
This study aimed to develop a comprehensive instrument for evaluating and ranking clinical practice guidelines, named Scientific, Transparent and Applicable Rankings tool (STAR), and test its reliability, validity, and usability.
METHODS:
This study set up a multidisciplinary working group including guideline methodologists, statisticians, journal editors, clinicians, and other experts. Scoping review, Delphi methods, and hierarchical analysis were used to develop the STAR tool. We evaluated the instrument's intrinsic and interrater reliability, content and criterion validity, and usability.
RESULTS:
STAR contained 39 items grouped into 11 domains. The mean intrinsic reliability of the domains, indicated by Cronbach's α coefficient, was 0.588 (95% confidence interval [CI]: 0.414, 0.762). Interrater reliability as assessed with Cohen's kappa coefficient was 0.774 (95% CI: 0.740, 0.807) for methodological evaluators and 0.618 (95% CI: 0.587, 0.648) for clinical evaluators. The overall content validity index was 0.905. Pearson's r correlation for criterion validity was 0.885 (95% CI: 0.804, 0.932). The mean usability score of the items was 4.6 and the median time spent to evaluate each guideline was 20 min.
CONCLUSION
The instrument performed well in terms of reliability, validity, and efficiency, and can be used for comprehensively evaluating and ranking guidelines.

OBJECTIVE:
Arsenic (As) and fluoride (F) are two of the most common elements contaminating groundwater resources. A growing number of studies have found that As and F can cause neurotoxicity in infants and children, leading to cognitive, learning, and memory impairments. However, early biomarkers of learning and memory impairment induced by As and/or F remain unclear. In the present study, the mechanisms by which As and/or F cause learning memory impairment are explored at the multi-omics level (microbiome and metabolome).
METHODS:
We stablished an SD rats model exposed to arsenic and/or fluoride from intrauterine to adult period.
RESULTS:
Arsenic and/fluoride exposed groups showed reduced neurobehavioral performance and lesions in the hippocampal CA1 region. 16S rRNA gene sequencing revealed that As and/or F exposure significantly altered the composition and diversity of the gut microbiome,featuring the Lachnospiraceae_NK4A136_group, Ruminococcus_1, Prevotellaceae_NK3B31_group, [Eubacterium]_xylanophilum_group. Metabolome analysis showed that As and/or F-induced learning and memory impairment may be related to tryptophan, lipoic acid, glutamate, gamma-aminobutyric acidergic (GABAergic) synapse, and arachidonic acid (AA) metabolism. The gut microbiota, metabolites, and learning memory indicators were significantly correlated.
CONCLUSION
Learning memory impairment triggered by As and/or F exposure may be mediated by different gut microbes and their associated metabolites.

Aim To investigate the anti-inflammatory effect of L-Shikonin ( SK ) on lipopolysaccharide ( LPS)-induced RAW 264. 7 macrophages in vitro and its protective effect on LPS/D-GalN-induced acute liver injury. Methods The mouse model of acute liver in¬jury was established in vivo experiments by LPS/D- GalN. The survival rate of the mice and the changes of liver and spleen indices in each group were examined. The levels of AST, ALT and AKP in serum and NO, superoxide dismutase ( SOD ) and malondialdehyde (MDA) in liver tissue homogenate were measured, and the histopathological sections of the liver of each group were observed by H&E staining. M I T colorimet- ric assay was used for cell viability in vitro experi¬ments, Griess method for the detection of NO content, RT-PCR assay and Western blot assay for examining the effect of levulinic acid on the expression levels of mRNA and related pathway proteins of pro-inflammato¬ry factors in LPS-induced RAW264. 7 cells. Results The results of in vivo experiments showed that L-SK significantly improved the liver and spleen indices, de¬creased AST, ALT and AKP levels in serum, de¬creased NO and MDA in liver homogenate, and in¬creased SOD activity in mice with acute liver injury. The results of in vitro experiments showed that L-SK significantly inhibited the mRNA expression of INOS, COX2, I FN-(3 and pro-inflammatory factors 1L-6, TNF-a and IL-10 in LPS-induced RAW264. 7 cells, and significantly inhibited the protein expression of IN¬OS, COX2 and the NF-kB signaling pathway. Conclu¬sions L-SK has good anti-inflammatory effects in LPS-induced inflammation in RAW 264. 7 cells in vitro. Il inhibits the protein expression of phosphorylated P65 and IKKaαβ in the NF-kB signaling pathway, thereby suppressing the anti-inflammatory effects in vitro and L- Shikonin has protective effects against acute liver injury in mice.

Blau syndrome is a rare genetic disorder characterized by the a mix of granulomatous arthritis, uveitis, and dermatitis. Patients typically manifest multisystem involvement, including ocular, skin, and skeletal abnormalities. Blau syndrome is extremely rare, with a global incidence of less than one in a million among children. In this multidisciplinary consultation, we present a case of a 21-year-old young female patient having multisystemic involvement since early childhood. She was presented with multiple joint swelling, skin lesions, increased eye discharge, and accompanied by hypertension and arterial abnormalities, and received a diagnosis of uveitis. The patient had been receiving steroid treatment since the age of 6 and has tried various medications, with some improvement in joint swelling and ocular symptoms. Through this rare disease multidisciplinary consultation, we aim to provide guidance in the molecular diagnosis of the patient, multisystem assessment, and the selection and formulation of treatment plans. Additionally, we hope that by reporting this case, clinical physicians can gain a better understanding of the diagnosis and comprehensive treatment strategies for Blau syndrome, thereby improving the management and treatment of rare diseases.
