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.

OBJECTIVES: To explore the mediating role of sleep duration in the relationship between depression symptoms and myopia among middle school students. METHODS: This study was a cross-sectional research conducted using a stratified cluster random sampling method. A total of 1 728 middle school students were selected from two junior high schools and two senior high schools in certain urban areas and farms of the Xinjiang Production and Construction Corps. Questionnaire surveys and vision tests were conducted among the students. Spearman analysis was used to analyze the correlation between depression symptoms, sleep duration, and myopia. The Bootstrap method was employed to investigate the mediating effect of sleep duration between depression symptoms and myopia. RESULTS: The prevalence of myopia in the overall population was 74.02% (1 279/1 728), with an average sleep duration of (7.6±1.0) hours. The rate of insufficient sleep was 83.62% (1 445/1 728), and the proportion of students exhibiting depression symptoms was 25.29% (437/1 728). Correlation analysis showed significant negative correlations between visual acuity in both eyes and sleep duration with depressive emotions as measured by the Center for Epidemiologic Studies Depression Scale (with correlation coefficients of -0.064, -0.084, and -0.199 respectively; P<0.01), as well as with somatic symptoms and activities (with correlation coefficients of -0.104, -0.124, and -0.233 respectively; P<0.01) and interpersonal relationships (with correlation coefficients of -0.052, -0.059, and -0.071 respectively; P<0.05). The correlation coefficients for left and right eye visual acuity and sleep duration were 0.206 and 0.211 respectively (P<0.001). Sleep duration exhibited a mediating effect between depression symptoms and myopia (indirect effect=0.056, 95%CI: 0.029-0.088), with the mediating effect value for females (indirect effect=0.066, 95%CI: 0.024-0.119) being higher than that for males (indirect effect=0.042, 95%CI: 0.011-0.081). CONCLUSIONS Sleep duration serves as a partial mediator between depression symptoms and myopia in middle school students.

OBJECTIVE: To assess health equity in the Yangtze River region to improve understanding of the correlation between hand, foot, and mouth disease (HFMD) and socioeconomic factors. METHODS: From 2014-2016, data on HFMD incidence, population statistics, economic indicators, and meteorology from 26 cities along the Yangtze River were analyzed. A multi-city random-effects meta-analysis was performed to study the relationship between temperature and HFMD transmission, and health equity was assessed with respect to socio-economic impact. RESULTS: Over the study period, 919,458 HFMD cases were reported, with Shanghai (162,303) having the highest incidence and Tongling (5,513) having the lowest. Males were more commonly affected (male-to-female ratio, 1.49:1). The exposure-response relationship had an M-shaped curve, with two HFMD peaks occurring at 4 °C and 26 °C. The relative risk had two peaks at 1.30 °C (1.834, 95% CI: 1.204-2.794) and 31.4 °C (1.143, 95% CI: 0.901-1.451), forming an M shape, with the first peak higher than the second. The most significant impact of temperature on HFMD was observed between -2 °C and 18.1 °C. The concentration index (0.2463) indicated moderate concentration differences, whereas the Theil index (0.0418) showed low inequality in distribution. CONCLUSION The incidence of HFMD varied across cities, particularly with changes in temperature. Economically prosperous areas showed higher risks, indicating disparities. Targeted interventions in these areas are crucial for mitigating the risk of HFMD.

Objective To analyze the influence of drainage volume on prognosis of acute hydrocephalus(AHC)after aneurysmal subarachnoid hemorrhage(aSAH)by continuous lumbar drainage.Methods A retrospective trial was conducted on 82 AHC patients after aSAH admitted to the First Affiliated Hospital of Chongqing Medical University between January 2017 and January 2022.In 6 months after discharge,modified Rankin Scale(mRS)score was used to evaluate the prognostic outcomes.Univariate and multivariate logistic regression analyses were performed on demographic factors,severity of subarachnoid hemorrhage(SAH)at admission,medical history,cerebral vasospasm,and lumbar drainage data.Then a nomogram prediction model was constructed.Results Univariate analysis found that World Federation of Neurosurgical Societies(WFNS)score,Hunt-Hess grade,modified Fisher grade,time for continuous lumbar drainage,shunt dependence,cerebral vasospasm,and drainage volume were factors affecting the prognosis of the patients.Then logistic regression analysis revealed that high WFNS score(OR:3.25,95％CI:1.11～9.48),high modified Fisher grade(OR:3.66,95％CI:1.08～12.35),shunt dependence(OR:15.56,95％CI:1.22～198.57),and cerebral vasospasm(OR:22.24,95％CI:3.08～160.68)were independent predictors for mRS score,while volume of continuous lumbar drainage(OR:0.57,95％CI:0.40～0.82)was an independent protective factor.ROC curve analysis indicated a good predictive performance of the model(AUC=0.898,95％CI:0.935～0.861).Internal validation through Bootstrap method demonstrated excellent discriminatory ability of the model(C-index=0.950,95％CI:0.904～0.996;adjusted C-index:0.934).Conclusion Increased volume of lumbar drainage is an independent protective factor for poor prognosis following aSAH and can improve the prognosis of SAH patients.

Objective To investigate the distribution of traditional Chinese medicine(TCM)constitution in pregnant women with iron deficiency anemia(IDA)and its related influencing factors,so as to provide a reference for the TCM prevention and treatment of IDA in pregnancy.Methods A total of 109 eligible patients with IDA during pregnancy were included in the study.The general data of pregnant women,the TCM constitution types and relevant laboratory indicators including serum ferritin(Fer),hemoglobin(Hb)and mean corpuscular volume(MCV)were collected.Statistical analyses were conducted on the distribution of TCM constitution types of IDA pregnant women and its related influencing factors as well as the pregnancy outcomes.Results(1)The 109 IDA pregnant women were predominated by biased constitution types,accounted for 60 cases(55.05％).The distribution of the constitution types of 109 IDA pregnant women was as follows:balanced constitution(49 cases,44.95％)>damp-heat constitution(13 cases,11.93％)>yang deficiency constitution(12 cases,11.01％)>yin deficiency constitution(11 cases,10.09％)>qi deficiency constitution(10 cases,9.17％)>qi stagnation constitution(9 cases,8.26％)>blood stasis constitution(3 cases,2.75％)>phlegm-damp constitution(2 cases,1.83％).(2)Comparison of Hb and MCV levels in IDA pregnant women with various constitution types showed no statistically significant differences(P>0.05),but Fer level in IDA pregnant women with damp-heat constitution was significantly higher than that in IDA pregnant women with balanced constitution(P<0.01),and the probability of occurrence of amniotic opacity in IDA pregnant women with damp-heat constitution was significantly higher than that in IDA pregnant women with balanced constitution and other biased constitution types(P<0.05).Conclusion Damp-heat constitution is the most common TCM constitution type in pregnant women with IDA,followed by yang deficiency constitution,yin deficiency constitution and qi deficiency constitution.The damp-heat constitution may be the susceptible constitution of pregnant women with IDA,and IDA pregnant women with damp-heat constitution have significantly higher Fer level than those with balanced constitution,and also have the higher probability of occurrence of amniotic opacity than those with balanced constitution and other biased constitution types.

Objective To observe the efficacy of Asini Corii Colla for the treatment of women with pregnancy anemia induced by β-thalassemia and its effect on the expression of early growth response 2(EGR2).Methods Transcriptome sequencing(RNA-seq)was performed firstly.Twenty pregnant women with β-thalassemia were randomly assigned to the treatment group and the control group at the proportion of 3:1.There were 15 cases allocated to the treatment group,one case fell off during the trial,and eventually 14 cases were included.The control group had 5 cases.The treatment group was given Asini Corii Colla powder orally,and the control group had no intervention.The course of treatment covered 4 weeks.The peripheral blood of the two groups of pregnant women was sampled before and after treatment for RNA-seq analysis,and then the candidate targets were defined.Subsequently,a prospective clinical randomized controlled trial(RCT)was conducted.A total of 41 pregnant women with β-thalassemia were randomly assigned to the treatment group(24 cases)and the control group(17 cases)at the proportion of 3:2.The treatment group was treated with Asini Corii Colla powder orally,and the control group was treated with the simulant of Asini Corii Colla Powder orally.The course of treatment covered 4 weeks.The hematological parameters of the two groups of pregnant women were detected before and after treatment,and the mRNA and protein expression levels of candidate targets were detected by real-time polymerase chain reaction(real-time PCR)and western blotting respectively.Results(1)The results of RNA-seq analysis showed that EGR2 expression of patients with genotype βCD41-42(-TTCT)/βN in the treatment group was significantly up-regulated after treatment(log2 FC=1.915;Padj=9.84E-03),and EGR2 was named as the candidate target.(2)The results of RCT showed that after treatment,there was no significant difference in the average hemoglobin(Hb)concentration between the two groups of pregnant women with β-thalassemia(P＞0.05),but the average Hb of the patients with genotypeβCD41-42(-TTCT)/βN in the treatment group increased by(6.54±4.74)g/L,which was significantly higher than that of other genotypes of pregnant women with β-thalassemia(P＜0.05).The expression levels of EGR2 Mrna and protein in peripheral blood of the patients with genotypeβCD41-42(-TTCT)/Βn in the treatment group were significantly increased after treatment(P＜0.05).The pre-and post-treatment difference of Hb concentration in the two groups of pregnant women withβ-thalassemia was positively correlated with pre-and post-treatment difference of EGR2 Mrna level and EGR2 protein level,and the correlation coefficients were 0.701 and 0.683,respectively(P＜0.001).Conclusion The pregnant women with thalassemia of genotype Βcd41-42(-TTCT)/Βn can achieve satisfactory efficacy after oral administration of Asini Corii Colla.Its curative effect for improving anemia may be related to the transcriptional regulation of globin genes through up-regulating EGR2 expression,activating RNA polymerase Ⅱ promoter,and promoting nucleic acid binding.

Objective:To analyze the types of genetic variants and clinical characteristics of three Chinese pedigrees affected with Hereditary coagulation factor Ⅶ (FⅦ) deficiency.Methods:Three pedigrees who had visited the First Affiliated Hospital of Wenzhou Medical University between December 2021 and October 2022 were selected as the study subjects. Prothrombin time (PT), activated partial thromboplastin time (APTT) and FⅦ activity (FⅦ: C) were measured in the three probands and their pedigree members. All exons and their flanking sequences were analyzed by direct sequencing, and candidate variants were verified by reverse sequencing. The corresponding variant loci in the family members were also analyzed. ClustalX-2.1-win was used to analyze the conservation of the variant loci. Varcards and Spcards online software was used to predict the pathogenicity of the variants. Pymol software was used to analyze the changes in protein structure and molecular forces.Results:Three cases of hereditary FⅦ deficiency were found to have decreased FⅦ: C, prolonged PT and normal APTT. Genetic analysis identified a total of four genetic variants, and all three probands had harbored compound heterozygous variants of the F7 gene, including p. Cys389Gly and p. His408Gln in proband 1, p. Cys389Gly and IVS6+ 1G>T in proband 2, and IVS6+ 1G>T and IVS1a+ 5G>A in proband 3. Conservation analysis showed that both the p. Cys389 and p. His408 loci are highly conserved among orthologous species. Analysis with Varcards and Spcards software showed that these variants were pathogenic. Protein modeling analysis showed that the p. Cys389Gly and p. His408Gln variants may result in altered protein structures and changes in hydrogen bonds. Conclusion:The clinical manifestations of the three FⅦ-deficient probands may be attributed to the compound heterozygous variants of p. Cys389Gly/p.His408Gln, p. Cys389Gly/ⅠⅤS6+ 1G>T and ⅠⅤS6+ 1G>T/ⅠⅤS1a+ 5G>A of the F7 gene. The combination of the three compound heterozygous variants was unreported previously.

The presence of 4-aminophenol(4-AP)in wastewater from the pharmaceutical industry is a common occurrence due to its role as a byproduct or intermediate during the hydrolysis process of paracetamol metabolism,resulting in significant water pollution.Therefore,it is crucial to employ a straightforward and reliable analytical approach for detecting 4-AP in the environment.In this study,a specific type of metal-organic framework(MOF)material called[Cd4(ABTC)2(H2O)12]n(SXNU-4-Cd,H4ABTC=3,3′,5,5′-azobenzene tetracarboxylic acid)was successfully synthesized,which exhibited a unique two-dimensional layered structure consisting of three intertwined spiral chains forming a distinctive″twist braid″.These layers underwent π-π stacking,creating three-dimensional channels with azo bonds decorating the channel walls.This p-π interaction significantly enhanced the adsorption capacity of SXNU-4-Cd towards 4-AP,thereby improving its recognition sensitivity.The fabricated SXNU-4-Cd/GCE sensor showed high sensitivity towards 4-AP in the linear concentration range of 0.1-130 μmol/L,with a detection limit of 8.6 nmol/L,and also exhibited good anti-interference capability,reproducibility and stability.The SXNU-4-Cd/GCE sensor was successfully used for detecting 4-AP in lake water sample,with spiked recoveries of 95.9%-102.8%.This study introduced a novel technique that utilized pure Cd-MOFs to develop electrochemical sensor capable of effectively detecting 4-AP in water samples.
