Sinisan is a classical prescription developed and applied by ancient medical experts and it is first recorded in the Treatise on Cold Damage written by ZHANG Zhongjing in the Eastern Han Dynasty. Later physicians have modified this prescription based on this original one. The bibliometrics methods were used to analyze the key information and research trend of Sinisan. According to the inclusion and exclusion criteria， 69 pieces of effective data were extracted， involving 67 ancient traditional Chinese medicine （TCM） books. The results showed that the name， composition， and decocting methods of Sinisan in later generations were inherited from the original record in the Treatise on Cold Damage. The original plants of medicinal materials used in Sinisan are basically clear. We recommend Bupleuri Radix as the dried root of Bupleurem scorzonerifolium， Paeoniae Radix Alba as the dried root of Paeonia lactiflora， Aurantii Fructus as the dried fruit of Citrus aurantium， Glycyrrhizae Radix et Rhizoma as the dry root and rhizome of Glycyrrhiza uralensis. Raw materials of Bupleuri Radix and Paeoniae Radix Alba， Aurantii Fructus stir-fried with bran， and stir-fried Glycyrrhizae Radix et Rhizoma should be used for preparation of Sinisan. According to measurement system in the Han Dynasty， a bag of Sinisan is composed of 1.25 g Bupleuri Radix， 1.25 g Paeoniae Radix Alba， 1.25 g Aurantii Fructus， and 1.25 g Glycyrrhizae Radix et Rhizoma. The materials should be grounded into coarse powder and taken with a proper amount of rice soup， 3 times a day. Sinisan has the effects of regulating qi movement and harmonizing the liver and spleen. It can be used for treating reversal cold in limbs and cold damage. In modern clinical practice， Sinisan can be used to treat chronic gastritis， irritable bowel syndrome， and dyspepsia. The above research results provide scientific reference for the future research and development of Sinisan.

OBJECTIVE To standardize the strategies for prevention and control of Chikungunya(CHIK)in healthcare in-stitutions so as to reduce the risk of transmission in the institutions.METHODS A working group comprising the ex-perts in hospital infection control,infectious diseases,and microbiology systematically reviewed domestic and international evidence and current guidelines,integrated China's vector ecology and healthcare realities,conducted two rounds of Delphi to achieve expert consensus,and graded the evidence and recommendation strength using the Oxford Centre for Evidence Based Medicine system.RESULTS The consensus issues 18 actionable recommendations on triage,patient mosquito-proof isolation,integrated vector control,protection of susceptible populations,environmental cleaning and disinfection,specimen management,medical textile handling,and outbreak emergency response,with each statement assigned an evi-dence level and recommendation strength.CONCLUSION This consensus is for the first time in China to provide evidence-graded strategies for control of CHIK in healthcare institutions,offering work flow-oriented,implementable guidance for clinicians,laboratorians,and infection-control personnel under different risk scenarios and enhancing the comprehensive coping capacity of the healthcare institutions.

Objective:To explore the relationship between urinary cadmium levels and thyroid hormone levels in people aged 40-89 years old in selected areas of China.Methods:Based on the "Investigation of the Impact of Soil Quality of Agricultural Land on Human Health in Typical Areas" project from October 2019 to August 2020, a multi-stage stratified random sampling method was used to include 6 588 middle-aged and older adults aged 40-89. Demographic characteristics, dietary frequency and disease status were collected through the questionnaire and physical examination. Urinary cadmium and urinary creatinine were detected by random midstream urine. Fasting venous blood was collected for the detection of Triiodothyronine (T3) and Thyroxine (T4). The linear mixed effects model was used to explore the association of urine cadmium levels with thyroid hormone levels. Its dose-response relationship was explored by using the restricted cubic spline.Results:The age of the subjects was (63.48±12.18) years, with males accounting for 51.28%. The M ( Q 1,Q 3) of urinary cadmium level, T3 and T4 was 2.48 (1.36, 4.42) μg/g·creatinine, (1.96±0.51) nmol/L and (113.75±29.11) nmol/L, respectively. The linear mixed effects model showed that the changes of T3 and T4 were 0.027 (0.009, 0.044) nmol/L and 2.019 (1.084, 2.953) nmol/L for each one-unit increase (natural logarithm transformed) of urinary cadmium. The restricted cubic spline showed that there was a positive nonlinear association between urinary cadmium and T3 as well as T4 (all Pnonlinear<0.05). Conclusion:In selected areas of China, the urinary cadmium level of middle-aged and older adults aged 40-89 years is positively associated with T3 and T4.

Objective To discuss the potential mechanisms by which programmed cell death(PCD)might contribute to the pathogenesis of diabetic kidney disease(DKD).Methods Retrieve the datasets GSE30529 and GSE30122 from the Gene Expression Omnibus database and analyze them to obtain differentially expressed genes(DEGs)associated with DKD.Utilize the Gene Set Enrichment Analysis website,the ferroptosis database,and the autophagy database,along with relevant literature,to identify genes associated with apoptosis,necroptosis,pyroptosis,autophagy,and ferroptosis.Cross-reference these genes with the DKD DEGs to identify PCD-related genes that are differentially expressed in DKD.Perform Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses to explore the biological functions and potential pathways of the core genes.Conduct a protein-protein interaction network analysis to examine the interaction relationships of the target genes,and use the CytoHubba plugin in Cytoscape to screen for Hub genes.Results In the GSE30529 dataset,a total of 460 DEGs were identified,while the GSE30122 dataset yielded 992 DEGs.After merging and removing duplicates,932 DEGs were obtained.By intersecting these DEGs with PCD-related genes,61 apoptosis-related genes,7 necroptosis-related genes,39 pyroptosis-related genes,18 autophagy-related genes,and 16 ferroptosis-related genes associated with DKD were identified.The KEGG analysis results indicated that the DEGs related to apoptosis,necroptosis,pyroptosis,and autophagy in PCD were primarily enriched in pathways associated with diabetic complications,including the AGE-RAGE,IL-17,NF-κB,and TNF signaling pathways.In contrast,DEGs related to ferroptosis were mainly enriched in the fatty acid degradation pathway.GO enrichment analysis revealed that the biological processes of the differentially expressed PCD related genes in DKD were primarily involved in the regulation of signals such as NF-κB-inducing kinase/NF-κB,IL-1,and IL-17.Conclusions Differentially expressed PCD-related genes in DKD are mainly enriched in related signal pathways such as AGE-RAGE,IL-17,NF-κB and TNF,suggesting a critical role of PCD in the pathogenesis of DKD.

Objective:To investigate the relationship between state anxiety and childhood subjective socioeco-nomic status(CSSES),and to examine the moderating role of cognitive reappraisal.Methods:A total of 998 col-lege students completed a set of questionnaires consisting of state trait anxiety scale,childhood socioeconomic scale and emotion regulation strategy scale,to assess their state anxiety,childhood subjective socioeconomic status and the ability of cognitive reappraisal.SPSS macro program Process and Bootstrap method were used to examine the mod-erating role of cognitive reappraisal in the relationship between the CSSES and state anxiety.Results:The results showed that the scores of state anxiety were negatively correlated with the scores of childhood subjective socioeco-nomic status(r=-0.14,P＜0.01),and the scores of state anxiety were negatively correlated with the scores of cognitive reappraisal(r=-0.30,P＜0.01).Moreover,cognitive reappraisal played a moderating role in the rela-tionship between CSSES and state anxiety(β=0.06).Conclusion:These findings indicate state anxiety may be negatively associated with the childhood subjective socioeconomic status,and the cognitive reappraisal moderates the relationship between the state anxiety and the childhood subjective socioeconomic status.

Objective To explore the value of magnetic resonance relaxation time quantitative imaging in predicting molecular subtypes of invasive ductal carcinoma(IDC)of breast.Methods A total of 79 IDC patients underwent routine magnetic resonance imaging(MRI)scanning and relaxation time quantitative imaging.According to immunohistochemical results of lesions,patients were divided into different immunohistochemical index groups and molecular subtype groups.The differences in MRI signs,T1 values and T2 values of lesions were statistically compared between each group.Patient operating characteristic(ROC)curve was used to evaluate values of T1 and T2 alone and the combination of them in differential diagnosis of IDC molecular subtypes.Results There were 82 samples of lesion in 79 patients,in which,Luminal A type 16(19.51%),Luminal B1 type 11(13.41%),Luminal B2 type 27(32.93%),tyrosine kinase receptor-2 overexpression type(Erb-B2)14(17.07%)and TNBC 14(17.07%).There were no significant differences in patient age,lesion distribution,maximum diameter,morphology,margin and enhancement performance between patients with various molecular subtypes(P>0.05).Among the immunohistochemical indexes,only the Ki-67 positive group had higher T1 value than the negative group(P<0.05).In ROC analysis,the critical T1 value of Ki-67 positive lesions was 2 145 ms,Yoden index was 0.368,the sensitivity was 53.47%,the specificity was 83.33%and the area under the curve(AUC)was 0.640(95%CI:0.527-0.744).There were no significant differences in T1 and T2 values between Luminal A,Luminal B1,Luminal B2,Erb-B2 enriched and TNBC subtypes(P<0.05).T1 and T2 values were lower in Luminal type lesion than those of TNBC type lesion(P＜0.05).ROC curve analysis showed that the combined T1 and T2 values were more effective in differentiating Luminal/TNBC type than those of T1 and T2 values alone.Conclusion T1 mapping can be used as one of the methods to predict the high or low expression levels of Ki-67 in IDC tumors.The combination of T1 and T2 values can improve the ability to predict Luminal/TNBC subtypes.
