This paper interprets the disease name related to bi （痹） disease in traditional Chinese medicine （TCM） from the perspective of micropathological phenotypes in knee osteoarthritis （KOA）. By systematically reviewing classical TCM literature on the pathogenesis and clinical features of different subtypes such as damp-retention bi， bone bi， and tendon bi， and integrating these with current research on pathological subtypes of KOA including the synovitis type， cartilage-meniscus type， and subchondral bone type， the study explores the correlation between traditional disease terms and modern micropathological phenotypes. The author proposes subtype classifications of damp-retention bi corresponding to synovial inflammation， bone bi related to abnormal subchondral bone remodeling， and tendon bi representing cartilage and meniscus degeneration. This approach provides a microscopic biological explanation for TCM syndrome differentiation and offers new perspectives for advancing integrative diagnostic and therapeutic strategies in both Chinese and western medicine.

ObjectiveTo evaluate the overall dietary intake of adult residents in Sijing Town, Songjiang District, Shanghai, and to explore the association between dietary health literacy and diet quality. MethodsA total of 1 280 adult residents were selected as the research subjects using a multi-stage sampling method, and face-to-face questionnaire surveys were administered on site. Dietary intake data were collected using a Food Frequency Questionnaire (FFQ), and the overall diet quality of the participants was evaluated based on the Chinese Healthy Eating Index (CHEI). Participants were divided into low- and high-CHEI groups according to the median CHEI score. Logistic regression models were used to examine the association between dietary health literacy and diet quality. ResultsThe median CHEI score for adults in the area was 63.68 points. Multivariate logistic regression analysis revealed that adults with lower dietary health literacy had lower CHEI scores and poorer overall diet quality compared to those with higher dietary health literacy (OR=1.435, 95%CI:1.132‒1.819). ConclusionThe overall diet quality of adult residents in this region requires improvement. There is a significant positive correlation between the level of dietary health literacy and CHEI scores, suggesting that enhancing dietary health literacy may be an important strategy to improve resident’ dietary quality.

In 2022, WHO updated the classification and concept of adrenal cortical and medullary tumors. In terms of adrenal cortical tumors, the WHO classification further standardizes the nomenclature of nodular adrenal cortical disease and refines the pathological classification of primary aldosteronism. In terms of adrenal medullary tumors, the WHO classification unifies the concepts of pheochromocytoma and paraganglioma, and reclassifies various concepts, including paraganglioma-like neuroendocrine tumors. The new standards not only cover the clinical manifestations of the disease, but also include other multiple aspects such as the histological origin of the disease, immunohistochemical manifestations, physiological mechanisms of the disease, hereditary susceptibility and prognostic factors. This article intends to explore how to improve the diagnostic and therapeutic level of adrenal tumors.

Objective To explore the clinical and imaging features of phosphaturic mesenchymal tumor(PMT).Methods The clinical presentations,laboratory examinations,and imaging manifestations of seven patients with PMT diagnosed by surgery and pathology were analyzed retrospectively.Results Among the 7 patients,four patients had clinical presentations of long-term fatigue and bone pain.All patients showed preoperative blood phosphorus reduction in varying degrees.X-ray examination showed systemic osteomalacia and osteoporosis,accompanied by multiple pathological fractures.On CT,the primary tumor appeared as a soft tissue density mass or a ground glass high-density nodule with irregular calcification and local bone destruction.MRI showed long T1,long T2 signal intensity,and irregular low signal foci were scattered in the T2WI fat-suppressed sequence.The enhanced scans showed moderate to significant inhomogeneous enhancement.One patient who underwent 18F-FDG PET/CT and two patients who underwent 18F-ALF-NOTA-Octreotide(18F-OC)PET/CT examinations showed varying degrees of radioactive concentration in the lesions.Conclusion The clinical presentations and laboratory examinations of patients with PMT have certain characteristics.Systemic osteomalacia with pseudofracture line,calcification matrix within the tumor,and significant inhomogeneous enhancement of the lesion are the key imaging features for diagnosing PMT.18F-OC PET/CT examination plays a crucial role in the systemic localization diagnosis of tumors.

Objective:To investigate the clinical efficacy of Cyclosporine A(CsA)in patients with unexplained repeated implantation failure(URIF),and to analyze the changes of peripheral blood lymphocyte subsets after CsA treatment.Methods:105 patients with URIF who underwent frozen-thawed embryo transfer(FET)in the De-partment of Reproductive Medicine in The Second Affiliated Hospital of Kunming Medical University from Septem-ber 30,2021 to March 1,2022 were selected.After informed consent,the patients were divided into CsA group(n=52)and control group(n=53)according to whether they received CsA treatment or not.Pregnancy outcomes and changes in lymphocyte subset were compared between the two groups.Results:The embryo implantation rate and clinical pregnancy rate in CsA group were higher than those in the control group,the difference was statisti-cally significant(48.91%vs.32.56%,P=0.027;53.85%vs.32.08%,P=0.024).The CsA group had a lower ear-ly abortion rate than the control group(10.71%vs.23.53%),but the difference was not statistically significant(P=0.25).The percentage of CD3-CD16+CD56+in CsA group was significantly decreased after treatment[(16.15±5.37)%vs.(18.23±7.10)%,P=0.012],it was also lower than that in the control group[(16.15±5.37)%vs.(18.67±5.16)%,P=0.018].Conclusions:CsA treatment can significantly improve the clinical preg-nancy rate and embryo implantation rate of frozen-thawed embryo transfer in patients with URIF,which may be a-chieved by promoting the distribution of peripheral blood lymphocytes to the direction of embryo implantation,es-pecially by down-regulating the percentage of CD3-CD16+CD56+.CsA has a certain application prospect in the field of assisted reproduction.

Tuberous sclerosis complex (TSC) is an autosomal dominant hereditary disease that affects multiple organs and systems throughout the body. TSC-associated kidney disease is the leading cause of death in adult TSC patients. This article retrospectively analyzed the characteristics of one TSC-related renal giant angiomyolipoma(RAML)treated with surgery. The patient, 25 years old, was diagnosed with tuberous sclerosis complex in 2000 due to multiple maculopapular rashes on both cheeks. At a regular follow-up in July 2019, imaging examinations revealed a tumor in the left lower quadrant with a maximum cross-sectional area of 16 cm×7 cm. Genetic testing showed a loss of heterozygosity in the EX18_ 41 of TSC2. After the diagnosis was confirmed, open left partial nephrectomy was performed, during which multiple tumors were found on the kidney surface and the largest one was located on the ventral side with a diameter of approximately 20 cm. After the renal artery was occluded, kidney tumors were completely enucleate. Postoperative pathological confirmed the diagnosis of angiomyolipoma. This case provides a reference for the treatment of TSC-related renal giant hamartoma.

Tuberous sclerosis complex(TSC) is a rare autosomal dominant genetic disorder caused by mutations in the TSC1 or TSC2 genes. The disease can cause multiple organ lesions. The most common renal lesions are renal angiomyolipoma(RAML). In recent years, China has made progresss in the understanding of TSC-RAML, so that the standardization of the diagnosis and management of TSC-RAML have improved. Efforts have been taken in the studies of the pathogenesis and treatment of TSC-RAML. This article reviews the diagnosis, therapy, and research development of TSC-RAML in China.

Tuberous sclerosis complex (TSC) is a rare autosomal dominant genetic disease involving multiple organ system. Renal angiomyolipoma (RAML) is a leading cause of death for adult TSC patients. Our study aims at investigating the clinical manifestations of TSC-RAML to enable clinicians to have a better understanding of the disease in Chinese patients.
