Objective: To investigate the objective characteristics of tongue manifestation in different stages of damp-heat syndrome in diabetic kidney disease (DKD). Methods: A cross-sectional study enrolled 134 patients with DKD G3-5 stages who met the diagnostic criteria for damp-heat syndrome in DKD. The patients were treated at Dongzhimen Hospital, Beijing University of Chinese Medicine, from May 2023 to January 2024. The patients were divided into three groups: DKD G3, DKD G4, and DKD G5 stage, with 53, 33, and 48 patients in each group, respectively. Clinical general data (gender, age, and body mass index) and damp-heat syndrome scores were collected from the patients. The YZAI-02 traditional Chinese medicine (TCM) AI Tongue Image Acquisition Device was used to capture tongue images from these patients. The accompanying AI Open Platform for TCM Tongue Diagnosis of the device was used to analyze and extract tongue manifestation features, including objective data on tongue color, tongue quality, coating color, and coating texture. Clinical data and objective tongue manifestation characteristics were compared among patients with DKD G3-5 based on their DKD damp-heat syndrome status. Results: No statistically significant difference in gender or body mass index was observed among the three patient groups. The DKD G3 stage group had the highest age (P<0.05). The DKD G3 stage group had a lower score for symptoms of poor appetite and anorexia(P<0.05) than the DKD G5 group. No statistically significant difference was observed in damp-heat syndrome scores among the three groups. Compared with the DKD G5 stage group, the DKD G3 stage group showed a decreased proportion of pale color at the tip and edges of the tongue (P<0.05). The DKD G4 stage group exhibited an increased proportion of crimson at the root of the tongue, a decreased proportion of thick white tongue coating at the root, a decreased proportion of pale color at the tip and edges of the tongue, an increased hue value (indicating color tone) of the tongue color in the middle, an increased brightness value (indicating color lightness) of the tongue coating color in the middle, and an increased thickness of the tongue coating (P<0.05). No statistically significant difference was observed in other tongue color proportions, color chroma values, body characteristics, coating color proportions, coating color chroma values, and coating texture characteristics among the three groups. Conclusion Tongue features differ in different stages of DKD damp-heat syndrome in multiple dimensions, enabling the inference that during the DKD G5 stage, the degree of qi and blood deficiency in the kidneys, heart, lungs, liver, gallbladder, spleen, and stomach is prominent. Dampness is more likely to accumulate in the lower jiao, particularly in the kidneys, whereas heat evil in the spleen and stomach is the most severe. These insights provide novel ideas for the clinical treatment of DKD.

Objective To evaluate the risk of right heart failure after heart transplantation by establishing nomogram based on preoperative pulmonary artery pressure.Methods A total of 184 patients undergoing heart transplantation were retrospectively collected and divided into the training group(126 cases)and the verification group(58 cases).Patients in the training set were divided into the right heart failure group(60 cases)and the non-right heart failure group(66 cases)according to whether right heart failure occurred after operation.The differences of clinical data between the two groups were compared,and the influencing factors of right heart failure occurred after operation in the training set were screened by Lasso-Logistic regression.According to the screened influencing factors,nomograms were drawn,and the predictive efficiency of the model was evaluated by using the receiver's operating characteristic(ROC)curve,calibration curve,receiver's operating characteristic(ROC)curve and clinical decision curve.Further vertification of the clinical application effect of centralized evaluation model was conducted.Results The Lasso-Logistic regression analysis identified the following independent risk factors for right heart failure after heart transplantation:elevated total bilirubin(OR=2.649,95％CI:1.339-5.239),increased mean pulmonary artery pressure(OR=3.082,95％CI:1.608-5.910),elevated pulmonary artery resistance(OR=3.171,95％CI:1.710-5.879),and widened right ventricular outflow tract diameter(OR=2.681,95％CI:1.361-5.281),all of which demonstrated statistical significance(P＜0.05).The nomogram model was constructed accordingly.The AUC of the nomogram model was 0.846(95％CI:0.813-0.947).The calibration curve demonstrated good fit via the goodness-of-fit test(Hosmer-Lemeshow x2=0.862,P=0.361).Clinical decision curve analysis revealed that the net benefit rate remained＞0 when the high-risk threshold probability ranged from 1％to 95％,indicating favorable clinical utility of this nomogram model.Based on the model predictions,among 58 heart transplant patients in the validation cohort,34 were classified as high-risk for right heart failure and 24 as low-risk.Actual diagnosis results showed 29 cases with right heart failure and 29 without.The Kappa coefficient reached 0.483(95％CI:0.261-0.705),demonstrating high consistency between model predictions and actual clinical outcomes.Conclusion Preoperative pulmonary systolic pressure increase is an independent risk factor for right heart failure after heart transplantation.A nomogram prediction model for right heart failure after heart transplantation is established by combining other clinical risk factors,and it has good prediction efficiency.

Ferroptosis is an iron-dependent form of regulated cell death,which is distinct from apoptosis,ne-crosis,and pyroptosis.Recent studies have found that activators of ferroptosis,such as Erastin,can activate autophagy-re-lated proteins,induce the formation of autophagosomes,and ultimately release ferric ions to mediate ferroptosis.This pro-cess,called ferritinophagy,is initiated by the binding of an autophagic cargo receptor protein,nuclear receptor coactivator 4(NCOA4),to iron-laden ferritin.The transfer of NCOA4-ferritin to the lysosome by ferritinophagy results in the proteoly-sis of ferritin,and,in turn,the release of its iron content and lipid-reactive oxygen species(ROS)accumulation.Ferritin-ophagy has been closely associated with central nervous system disorders,circulatory system diseases,and cancer.Fur-thermore,the regulation mechanism of ferritinophagy is also a hot topic in the study of iron-dependent cell death process.With the in-depth study of ferritinophagy,great progress has been made in the study of key components of ferritinophagy as well as its molecular mechanisms and processes.However,a comprehensive summary of the methods for detecting ferritin-ophagy is still unclear.To further deepen the understanding of ferritinophagy and its detection methods,this review focus-es on the concept,characteristics,methods,and precautions during detection of ferritinophagy.This review provided ex-perimental reference for subsequent researchers and promoting the progress of research related to ferritinophagy.

Hyperhidrosis is a disease in which excessive sweat is secreted,resulting in an abnormal increase in systemic or local perspiration.In traditional Chinese medicine,hyperhidrosis belongs to the category of sweating disease.It is caused by an imbalance between yin and yang and abnormal excretion of body fluid.Many doctors treat the sweating disease from the perspective of heart,lung,and kidney;in contrast,we discuss the etiology and pathogenesis of hyperhidrosis from the perspective of liver and spleen,explain the significance of harmonizing the liver and spleen to improve the sweating disease,and put forward the key pathogenic factors of stagnation liver qi and spleen deficiency,and disharmony between nutrient qi and defensive qi,and the imbalance between yin and yang are the key pathogenic factor.Most of the clinical treatment start from the liver and spleen.The main treatment principle is based on soothing the liver and relieving depression,invigorating the spleen and nourishing blood,and regulating and harmonizing the nutrient qi and defensive qi,paying attention to the relationship between qi and blood in zangfu organs,invigorating the spleen and replenishing qi to consolidate its foundation,soothing the liver and relieving depression to regulate its qi,and invigorating qi and blood and perspiration.Treatment can be supplemented with Xiaoyao Powder plus-minus,mainly to strengthen liver wood and spleen soil,acquire nourishment,smooth qi,nourish the five zang,reconcile qi and blood,enhance physical strength and peace of mind,ensure sufficient qi to arrest sweating,coordinate the liver and spleen,balance the ascending and descending phases,and harmonize the five zang organs.

ObjectiveTo study the conceptual framework and methodological system of the International Classification of Functioning, Disability and Health (ICF) in occupational therapy and its systematic implementation in clinical practice. MethodsBased on the ICF theory and the policy documents of the World Federation of Occupational Therapists, the conceptual framework of occupational therapy and the systematic implementation in clinical settings based on the ICF framework were analyzed. ResultsThis study constructed a conceptual framework and approach for occupational therapy based on ICF, and clarified the goals, principles, and implementation methods of integrated occupational therapy interventions in rehabilitation services. The goal of occupational therapy interventions was to improve the individual activity and participation through multidisciplinary and cross-cutting implementation of integrated occupational therapy programs to optimize functioning. Occupational therapy was based on the bio-psycho-social model, adhered to the principles of person-centeredness and functioning orientation, and implemented individualized intervention programs in different context. In clinical practice, it was recommended to follow ICF-based standardized process and systematically use World Health Organization Family International Classifications: functioning and unmet needs analysis using ICHI; functional classification, assessment and coding using ICF; disease classification, diagnosis and coding using ICD; intervention of occupational therapies using ICHI to build a systematic occupational therapy service system. ConclusionAn ICF-based occupational therapy concept and methodological system has been built, a comprehensive clinical occupational therapy implementation model has been established, the goal of activity and participation oriented occupational therapy interventions has been clarified, and the systematic, structured, standardized and refined level of occupational therapy has been enhanced.

Objective:To study the inter-fraction setup errors, intra-fraction movement of patients and its influence on dosimetry, position repeatability of the supraclavicular area, and the plastic stability of the vacuum cushion and styrofoam when one of the three fixation method are applied in the clinical radiotherapy of breast cancer. The three fixation method include acuum negative pressure pad (VP), acuum negative pressure pad combined with a breast bracket (VB), and polyurethane styrofoam combined with a breast bracket (PB).Methods:A total of 96 breast cancer patients who received radiotherapy at Jiangsu Cancer Hospital during 2019-2021 were collected prospectively for study. They were randomly divided into three groups (VP, VB, and PB). Cone-Beam CT and a planning system were used to obtain inter-fraction setup errors, intra-fraction movement of patients and its influence on dosimetry, position repeatability of supraclavicular area, and the plastic stability of vacuum pad and polyurethane tyrofoam.Results:In the left-right (LR) direction, there were no statistical differences in the inter-fraction setup errors among the three groups. In the superior-inferior (SI) direction, inter-fraction setup errors of the PB group were smaller than those of the VB group (3.02 ± 2.04, 3.65 ± 2.64, t=2.35, P=0.031). In the anterior-posterior (AP) direction, the inter-fraction setup errors of both the VB and PB groups were smaller than those of the VP group (3.36 ± 2.93, 3.14 ± 0.98, 4.03 ± 2.55, t=2.29, 3.11, P< 0.05). In the AP direction, the intra-fraction movement of patients of the VP and PB groups were less than that of the VB group (1.31 ± 0.95, 1.24 ± 0.89, 1.88 ± 1.33, t=-2.04, -2.31, P< 0.05). Moreover, the intra-fraction movement of patients had no statistical effect on the dosimetric distribution ( P> 0.05), and the breast bracket did not improve the position repeatability of the supraclavicular region ( P>0.05). In addition, the plastic stability of polyurethane styrofoam was significantly better than that of the acuum negative pressure pad ( t=2.43-5.63, P< 0.05). Conclusions:The inter-fraction setup errors and intra-fraction movement of patients with breast cancer can be reduced by using PB. Compared to an acuum negative pressure pad, polyurethane styrofoam can keep plastic stability throughout the treatment of the patients.

Objective:To investigate the prevalence of autism spectrum disorders (ASD)among children in kindergartens in Xi′an urban districts.Methods:A stratified cluster sampling method was adopted, and selected all children from 12 kindergartens in 6 urban districts of Xi′an.Primary screening positive children with ASD were identified by filling out the Autism Behavior Checklist (ABC) by their parents and the guardians reports, and then the beha-vioral observations were made to identify suspicious ASD children.Finally these children were diagnosed in the hospital through the autism diagnostic observation schedule, 2 nd edition (ADOS-2). The data were calculated with SPSS 18.0. Results:Totally, 38 cases with ASD were diagnosed among 5 178 children, the prevalence of children ASD in kindergartens in Xi′an urban districts was 7.3‰, and the 95% confidence interval was 4.98‰-9.62‰.The prevalence of ASD in children was statistically significant in different age groups ( χ2=9.914, P<0.05) and gender groups ( χ2=18.812, P<0.05). The accuracy of ASD screening by guardians reports is better than that by ABC. Conclusions:(1)The prevalence of ASD children in kindergartens in Xi′an urban districts is at high level in similar reports in China.If ASD children at the special education institutions and home are considered, the overall prevalence rate is higher, indicating that the prevalence of ASD children in China may be underestimated.(2)With the increase of age, the attendance rate of ASD children in kindergartens has a decreasing trend.

Objective:To explore the biochemical characteristics, virulence factors and other phenotypes of the strains of Yersinia pestis isolated in Jianchuan County Yunnan Province in 2017, and to analyze the nature and source of the new plague epidemic. Methods:Three strains of Yersinia pestis (JC109 rat, JC109 fleas and JC113) isolated from Daqing Village, Jinhua Town, Jianchuan County, Dali Prefecture, Yunnan Province in 2017, and 2 associated strains of Yersinia pestis (LJ01 in Yulong County, Lijiang City and LJ04 in Gucheng District of Lijiang City), 5 control strains ( Yersinia pestis JC1332, LJ485, BN2636, EV-76 and Yersinia pseudotuberculosis PST-1), preserved by the Central Laboratory of Yunnan Institute for Endemic Disease Control and Prevention were collected. The biochemical characteristics and ecotypes of Yersinia pestis were analyzed by using arabinose, rhamnose, denbiose, maltose and glycerol fermentation experiments and nitrate reduction experiments. Combining pigmentation factor (pgm), virulence antigen (VW) detection and nutritional requirements test results to determine the virulence of Yersinia pestis. Results:The Yersinia pestis JC109 rat, JC109 fleas and JC113 all fermented arabinose, maltose and glycerol, but didn't ferment rhamnose and denbiose; and the nitrate reduction test was positive. The ecological type belonged to the Himalayan Marmot plague strain of Qinghai-Tibet plateau. The virulence factors pgm and VW tests were positive, the nutritional requirement type was phenylalanine dependent and glutamate independent. It had the same phenotype as the LJ01 strain, but different from the JC1332 strain. Conclusions:The newly isolated strains in Jianchuan County are the same as those in the Lijiang Yulong wild rodent plague foci. This outbreak may have been imported from the Lijiang Yulong wild rodent plague foci to the south.
