Objective:To translate the Vascular Quality of Life Questionnaire-6 (VQ6) into a Chinese version and to test its reliability and validity in patients with peripheral arterial disease.Methods:The English version of VQ6 scale was sinicized following the Brislin translation guidelines, and the Delphi consultation was used for cultural debugging to form the Chinese version of the VQ6. Convenience sampling was used to select 146 patients with peripheral arterial disease who attended the Department of Interventional and Vascular Surgery and the Department of Endocrinology of Affiliated Hospital of Nantong University from May to June 2024 for the survey. Data were analyzed using SPSS 26.0 and Amos 26.0. Correlation analysis and critical ratio method were used for item analysis and content validity index was used to evaluate content validity. The Chinese version of the Patient-Reported Outcomes Measurement Information System 29 Profile V2.1 (PROMIS-29 Profile v2.1) was selected as a validity scale to evaluate the criterion-related validity. Exploratory factor analysis and confirmatory factor analysis were used to evaluate the structural validity of the scale, and transgender test was used for measurement equivalence. Reliability of the scale was evaluated with the Cronbach's α coefficient and retest reliability index.Results:The Chinese version of the VQ6 scale had six items. The scale-level content validity index was 0.972, and the item-level content validity index ranged from 0.833 to 1.000. One common factor was extracted with a cumulative variance contribution of 83.526%. Criterion-related validity showed that the correlation coefficient between the Chinese version of the VQ6 and the PROMIS-29 Profile v2.1 was 0.688 ( P<0.01) . The scale essentially satisfied Δ RMSEA < 0.015 and Δ CFI < 0.01 in the transgender equivalence test. The Cronbach's α coefficient for the scale was 0.968 and the retest reliability was 0.978. Conclusions:The Chinese version of the VQ6 has good reliability and validity and is suitable as an assessment tool for quality of life in patients with peripheral arterial disease in our cultural context.

Objective:To evaluate the accuracy of p53 immunohistochemistry for predicting the mutational status of TP53 in gliomas.Methods:A retrospective study was conducted on 242 diffuse gliomas diagnosed at the Department of Pathology, the First Affiliated Hospital of Fujian Medical University, Fuzhou, China from June 2022 to March 2023. All cases underwent next-generation sequencing (NGS) and p53 immunohistochemical staining. The best threshold in the percentage of p53 immunohistochemical expression was assessed as an alternative to testing for TP53 mutation.Results:Among the 242 diffuse gliomas (WHO grade 2-4), 94 cases had a TP53 mutation. The p53 immunohistochemistry results revealed a significantly increased probability of TP53 mutation when the p53 immunohistochemical positivity rate (based on strongly positive cell count) was ≥20% ( P<0.05). The sensitivity and specificity of p53 immunohistochemistry for predicting TP53 gene mutations were 75.6% and 90.4%, respectively. When p53 immunohistochemical stain was totally negative, the probability of TP53 mutation increased significantly, and the mutation ratio of TP53 gene was 6/17 in all negative cases. Conclusions:When the percentage of p53 positive cells (based on strongly positive cell count) in glioma is ≥20%, p53 immunohistochemistry can be used as a reliable alternative method for TP53 mutation detection. When p53 immunohistochemistry is completely negative, the mutation rate of TP53 gene is higher, and further gene sequencing is recommended to determine the mutation status.

Type 2 diabetes mellitus （T2DM） is a chronic metabolic disease characterized by insulin resistance， hyperinsulinemia， and disturbance of glucose and lipid metabolism， with elevated blood glucose as the main clinical manifestation. Due to its complex etiology and pathogenesis， there is no effective treatment， which critically threatens human health and places a heavy burden on society and families. Saponins are a class of glycosides with complex structures that have the advantage of a wide range of sources， elevated safety， and low adverse effects. As an essential active ingredient in Chinese medicine， Chinese medicine saponins have a variety of biological activities such as hypoglycemia， hypoglycaemia， anti-inflammation， antioxidation， anti-tumor， and immune modulation. In recent years， numerous studies have shown that Chinese medicine saponins are effective in preventing and treating T2DM. Although there have been numerous studies on the hypoglycemic effects and mechanisms of Chinese medicine saponins， there has been no systematic review of the mechanisms of Chinese medicine saponins in the treatment of T2DM. Therefore， to provide a theoretical basis for an in-depth study of the hypoglycemic effects of Chinese medicine saponins and a scientific basis for the development and clinical application of drugs， this paper systematically summarized the hypoglycemic mechanisms of Chinese medicine saponins， such as improving islet β-cell function， improving insulin resistance， inhibiting glycosidase activity， reducing the inflammatory response， anti-oxidative stress， and regulating intestinal flora， and analyzed the current research problems and development trends.

ObjectiveTo investigate the effect of Loulianwan on the gut microbiota of db/db mice with type 2 diabetes mellitus （T2DM）. MethodMale db/m+ mice aged 4-5 weeks were assigned to the normal group， and male db/db model mice of the same age were randomly divided into model group， metformin group （0.25 g·kg^-1·d^-1）， and Loulianwan group （13 g·kg^-1·d^-1）， with six mice in each group. Drug intervention lasted five weeks. The body weight， water intake， and fasting blood glucose （FBG） of the mice were recorded every week. After five weeks， the FBG， liver triglyceride （TG）， liver total cholesterol （TC）， glycated serum protein （GSP）， and fasting serum insulin （FINS） were detected， and the insulin resistance index （HOMA-IR） was calculated. The feces in the mouse intestines were collected， and the 16S rRNA sequencing technology was used to detect the structural changes in the fecal gut microbiota of mice in each group. ResultCompared with the normal group， the model group showed increased body weight， water intake， FBG， liver TG， liver TC， GSP， FINS， and HOMA-IR （P<0.01）. Compared with the model group， the Loulianwan group showed reduced water intake， FBG， liver TG， liver TC， GSP， FINS， and HOMA-IR （P<0.01）. The gut microbiota in the Loulian Lills group changed from phylum to genus level. The relative abundance of beneficial bacteria increased and the relative abundance of harmful bacteria decreased. Among them， the abundance of Akkermansia muciniphila， Blautia， Ruminococcus， and Parabacteroides increased （P<0.01）. ConclusionLoulianwan can significantly improve glucose and lipid metabolism in db/db mice with T2DM， and its mechanism may be related to the increase in the abundance of Akkermansia muciniphila， Blautia， Ruminococcus， and Parabacteroides in the intestine.

Objective To investigate the prevalence and specific manifestations of enduring psychological distress in patients with breast cancer after operation. Methods Totally 263 patients of the newly diagnosed breast cancer treated with the operation from August 2014 to August 2015 were collected by convenience sampling. Distress Thermometer (DT) and Problem List recommended by national Comprehensive Cancer Network was used to assess the persistent psychological distresses in the 6th, 15th, 20th, 25th, 30th months after the disease diagnosis,while a self-designed questionnaire was for the demographic data. Results The results of the DT screening showed that 16％(42/263) patients had persistent psychological problems;the incidences of five stages of significant psychological distress (DT≥4) was 43％(113/263), 34％(89/263), 31％(81/263), 28％ (73/263) and 25％ (65/263), respectively. The main manifestations of persistent psychological distress were:fatigue 59 cases (22.4％) , sleep disorders 51 cases (19.4％), nervous 48 cases (18.2％), anxiety 24 cases (9.1％), fear of appearance 23 cases (8.7％) and the difference in persistent psychological distress scores between different demographic characteristics (age, educational level, marital status, economic situation, operation method, disease stage) were statistically significant (t=-2.295-2.966, P<0.05). Conclusion The incidences of persistent psychological distress in patients with breast cancer is higher and the manifestation is different,which should be paid attention to by medical workers.
