This article aimed to summarize the clinical experience of treating sjögren's syndrome of yin-deficiency and heat-toxin type based on the theory of exuberance of shaoyang ministerial fire accumulating to heat toxin. It is believed that sjögren's syndrome of yin-deficiency and heat-toxin type is attributed to dysfunction of shaoyang gallbladder， disruption in the circulation of sanjiao， stagnation of qi leading to fire， and prolonged accumulation of toxins causing damage. The core disease mechanism involves shaoyang dysfunction， hyperactivity of ministerial fire， and accumulation of heat toxins. In clinical practice， the therapeutic principles focus on regulating shaoyang， stabilizing and subduing ministerial fire， enriching yin and resolving toxins. For shaoyang dysfunction with internal stagnation of heat toxins， treatment should aim to unblock shaoyang， clear fire and expel toxins， using modified Sangchai Decoction （桑柴饮）； for shaoyang transformation into fire with symptoms of wood （the gallbladder） disease， the approach involves soothing and regulating gallbladder， clearing heat and resolving toxins， using modified Chaihu Shaoyao Decoction （柴胡芍药汤）； for disordered ministerial fire with excessive heat toxins， the strategy is to rescue the sovereign fire and stabilize the ministerial fire， employing modified Xinshen Liangjiao Decoction （心肾两交汤）； for unregulated ministerial fire with disordered distribution， treatment focuses on increasing body fluids and nourishing yin， stabilizing the ministerial fire， using modified Buyin Decoction （补阴汤）.

This paper summarizes clinical experience in treating acne based on the staged therapeutic principles of "eruption in warm diseases". It is considered that acne results from wind-heat retained in the lungs， invading the ying level and obstructing the blood collaterals， and is primarily a disorder involving both the wei and ying systems. In clinical practice， the treatment emphasizes the use of acrid-cool and sweet-cold methods. The core prescription is namely Yinqiaosan Qu Douchi Jia Xishengdi Danpi Daqingye Bei Xuanshen Fang （from Epidemic Warm Diseases ［《温病条辨》］）， and is adjusted according to the stage of disease. In the non-inflammatory stage， when the pathogen initially attacks the wei level， treatment focuses on acrid-cool herbs to release the exterior， with supplementary bitter-sweet ingredients such as Yejuhua （Chrysanthemum Indicum）. In the inflammatory stage， with pronounced heat toxin in the qi level affecting the ying and blood， and local stagnation of qi and blood， the approach is to clear heat and resolve toxin， using blood-cooling and stasis-resolving herbs early to prevent progression. Herbs such as Pugongying （Taraxacum Mongolicum）， Zihuadiding （Viola Yedoensis）， Tiankuizi （Semiaquilegia Adoxoides）， Chonglou （Paris Polyphylla）， Machixian （Portulaca Oleracea）， Zaojiaoci （Gleditsia Sinensis）， Chuanshanjia （Manis Pentadactyla） may be added. In the post-inflammatory erythema stage， when yin of the ying level is depleted and internal deficiency-heat arises， sweet-cold herbs are recommended to nourish the stomach and generate fluids， with the possible addition of Yiwei Decoction （益胃汤）.

Breast cancer is the worldwide most common malignant tumor in women,and early diagnosis and treatment is the key to improve prognosis.Conventional screening imaging techniques,such as mammography and ultrasonography,have only limited diagnostic efficacy for micro breast cancer.Combining diffuse optical tomography(DOT)and ultrasonography for assessing blood vessel distribution and metabolic level inside the breast lesions,optical tomography image ultrasonography system(OPTIMUS)has unique advantages for diagnosing micro breast cancer with diameter≤1.0 cm.The research progresses of OPTIMUS for diagnosing micro breast cancer were reviewed in this article.

N6-methyladenosine(m6A)is produced by methylation of the 6th nitrogen atom of ade-nine.The m6A methylation modification is the most common internal modification of RNA,and the modifica-tion process mainly relies on m6A-related enzymes,including methyltransferases,demethylases and binding proteins.The core structure of the methyltransferase complex(MTC)is methyltransferase-like 3(METTL3).The pathogenesis of osteoarthritis(OA)is intricate and complex,and various factors interact with each other.This paper summarizes the mechanism of action of m6A and related enzymes,and elaborates the pathogenesis of os-teoarthritis from the aspects of chondrocytes,proteases,cytokines and signaling pathways,emphatically intro-duces the regulatory role of METTL3 on OA in m6A methylated modification.The aim is to provide new per-spectives on the pathogenesis of osteoarthritis in order to provide new ideas and approaches for the treatment of osteoarthritis.

Objective To investigate the diagnostic value of lumbar spine CT radiomics nomogram for osteoporosis(OP).Methods A total of 414 patients who underwent abdominal CT and quantitative computed tomography(QCT)examinations were retrospectively selected.The patients were randomly divided into a training group(n=290)and a validation group(n=124)at a ratio of 7∶3.Radiomics features were extracted from lumbar spine CT images.The least absolute shrinkage and selection operator(LASSO)algorithm was used for dimen-sion reduction and feature selection.Multivariable logisitic regression was used to build the radiomics signature and the radiomics nomo-gram.The area under the curve(AUC)of receiver operating characteristic(ROC)curve was used to analyze the diagnostic performance of the Radiomics score(Radscore)and radiomics nomogram in diagnosing OP.The DeLong test was used to compare the diagnostic performance between the two models.Results Eight radiomics features were selected to establish the Radscore.The AUC of the Radscore and radiomics nomograms in the validation group for distinguishing normal bone mass from reduced bone mass and OP,reduced bone mass from OP,and OP from reduced bone mass and normal bone mass were 0.891 and 0.976,0.866 and 0.976,0.897 and 0.982,respectively.According to the DeLong test,the AUC of the radiomics nomograms was significantly higher than that of the Radscore(P＜0.05).Conclusion The radiomics nomogram model based on lumbar spine CT can serve as a novel method for individualized assess-ment of OP and provide assistance to clinical decision-making.

Objective To investigate the correlation between tibial plateau varus and osteoporosis(OP)in postmenopausal women with knee osteoarthritis(KOA).Methods A retrospective analysis was conducted on 194 postmenopausal women with KOA who underwent unicompartmental knee arthroplasty.Various risk factors associated with tibial plateau varus[medial tibial plateau angle(MTPA)＜85°],including age,body mass index(BMI),Kellgren-Lawrence(K-L)grade,hip-knee-ankle angle(HKAA),lateral distal femur angle(LDFA),bone mineral density(BMD)were collected and analyzed.Multiple regression was employed to analyze the relationship of these factors with tibial plateau varus.Pearson's correlation coefficient was used to assess the association between MTPA and BMD.Results Multiple linear regression analysis revealed that BMD(β=0.381,P＜0.001)and HKAA(β=0.460,P＜0.001)were independent risk factors for tibial plateau varus.LDFA,age,BMI,K-L grade were not significantly associated with tibial plateau varus.A statistically significant association between BMD and tibial plateau varus was noted(r=0.817,P＜0.001).Further data stratification showed a significant association between BMD and tibial plateau varus in patients with knee varus(HKAA＜175°)(r=0.781,P＜0.001).There was no statistical significance association between BMD and tibial plateau varus in patients with normal lower extremity alignment(HKAA≥175°)(r=-0.035,P=0.063).Conclusion OP and knee varus emerge as the primary risk factors for tibial plateau varus in the knee in postmenopausal women with KOA.

Objective To investigate the curative effect of interventional therapy on postoperative multiple metastases of breast cancer.Methods A total of 15 patients with multiple metastases after breast cancer surgery were treated with interventional therapy.After comprehensive evaluation,all patients were treated with chemoembolization.The therapeutic regimen was docetaxel loaded on drug-eluting bead(DEB)combined with carboplatin,once in 1 d for 21 d,2 times in total,and then the regimen was changed to docetaxel and carboplatin combined with ordinary embolization microspheres,once in 1 d for 21 d,4 times in total.CT/MRI was performed on every 2 cycles and 1,3,and 6 months after interventional therapy to evaluate its efficacy and record adverse reactions.Results The overall remission rate(ORR)at 3 months after treatment was 75％,and the disease control rate(DCR)was 91.7％.The ORR and DCR at 6 months after treatment were 50％and 83.3％,respectively.Most of the common adverse reactions were below grade Ⅲ.Conclusion Interventional therapy for multiple metastases of breast cancer after operation has a definite short-term effect,with little adverse reactions.It is worthy of further promotion in the comprehensive treatment of postoperative metastases of breast cancer.

Objective To compare the bone mineral density and age-related bone loss rate of thoracic and lumbar vertebrae using quantitative CT(QCT),and to explore the feasibility of measuring bone density and bone loss rate using thoracic QCT.Methods A total of 708 patients who underwent full abdominal CT scans due to trauma,acute abdominal disease,and health examination from March 2022 to March 2023 were selected.The average BMD of T10 to L3 vertebral bodies were measured using quantitative CT software.The subjects were divided into several age groups according to the age of every 10 years.The average bone density and the age-related annual rate of bone density loss of the thoracic and lumbar vertebrae for each group were computed,the correlation analysis between thoracic and lumbar BMD and age was conducted using Pearson correlation analysis.Results The peak BMD for both males and females was in the 20 to 29 years age group.After the age of 30,the bone density of the thoracic and lumbar vertebrae began to decrease to varying degrees.For females aged 80 to 89,the cumulative bone loss rate for the thoracic and lumbar vertebrae was 60.61%and 61.34%,respectively,while for males,it was 44.45%and 49.35%,respectively.The BMD of the thoracic and lumbar vertebrae in both males and females showed a negative correlation with age(P<0.01).There was a significant positive correlation between the bone mineral density of the thoracic and lumbar vertebrae(for males,r = 0.96;for females,r = 0.98;P<0.01).Conclusion Both thoracic and lumbar QCT accurately displayed BMD and bone loss in different age groups,and thoracic QCT could be used as a method for evaluating and monitoring bone loss.

In many neurodegenerative diseases,eye movement is disrupted,which is a common and early characteris-tic of neurodegenerative diseases.Characterizing eye movement is important for the diagnosis of neurodegenerative disea-ses,helping to track disease progression and response to treatment.In recent years,eye tracking technology has been ap-plied to the assessment of cognitive function in patients with neurodegenerative diseases.Compared to traditional cognitive assessment methods,the technology has higher temporal and spatial resolution for sensitive quantification.Eye tracking da-ta confirms that executive dysfunction is common in Parkinson's disease and amyotrophic lateral sclerosis,while attention deficit is a characteristic of Alzheimer's disease and multiple sclerosis.Research using eye tracking to evaluate the cogni-tive function of epilepsy patients is still in its early stages,but this method has shown advantages.In this article,the appli-cation of eye tracking technology in neurodegenerative diseases is reviewed.
