OBJECTIVETo explore the distribution laws of TCM syndrome types and to analyze the distribution of dynamic blood pressure curve, atherosclerosis, and age in senile hypertension patients.

METHODSTotally 1 131 senile hypertension patients were recruited from 7 provinces and municipal cities. Features of TCM syndromes, classification and distribution curves, and syndrome distribution laws were observed. The distribution curves of dynamic blood pressure, carotid atherosclerosis, and age were compared in each TCM syndrome types.

RESULTSThere were four main syndrome types in 736 cases (56.15%), i.e., excessive accumulation of phlegm-dampness syndrome (210 cases, 16.02%), yin deficiency and hyperactivity of yang syndrome (177 cases, 13.50%), Gan-Shen yin deficiency syndrome (79 cases, 6.03%), and deficiency of qi and yin syndrome (252 cases, 19.22%). Besides, there were two more sub-types, i.e., collateral obstruction by blood stasis syndrome and collateral obstruction by phlegm and stasis. Circadian blood pressure monitor was completed in 211 cases. Of them, abnormal circadian blood pressure occurred in 152 cases (accounting for 72. 38%); yin deficiency and hyperactivity of yang syndrome, excessive accumulation of phlegm-dampness syndrome, deficiency of qi and yin syndrome plus collateral obstruction by blood stasis syndrome were most often seen. Color ultrasound of carotid artery was performed in 660 patients of main syndromes. The incidence was quite higher in those of excessive accumulation of phlegm-dampness syndrome (182 cases, 27. 58%), deficiency of qi and yin syndrome plus collateral obstruction by blood stasis syndrome or collateral obstruction by phlegm and stasis (322 cases, 48.79%). Yin deficiency and hyperactivity of yang syndrome was dominant in patients 60 -79 years old, while deficiency of qi and yin syndrome and Gan-Shen yin deficiency syndrome were dominant in patients older than 80 years.

CONCLUSIONSExcessive accumulation of phlegm-dampness syndrome, yin deficiency and hyperactivity of yang syndrome, Gan-Shen yin deficiency syndrome, and deficiency of qi and yin syndrome were main syndrome types in senile hypertension patients. There was statistical difference in the distribution curves of blood pressure, atherosclerosis, and age of various TCM syndrome types.

Objective To explore the clinical effect of Weikangling and Weifuchun treatment of chronic atrophic gastritis and precancerous lesions.Methods 85 cases of CAG precancerous lesions treated in our hospital from Jan.2012 to Dec.2016 were selected as the research object,and were randomly divided into control group (n =41) and study group (n =44).The control group were given Weifuchun,and the study group were given Wei Kangling.The pathological score and clinical efficacy were compared between the two groups before and after treatment.Results After treatment,inflammation,atrophy,intestinal metaplasia scores of the two groups were significantly decreased than before treatment in addition to dysplasia (P ＜ 0.05),and inflammation and intestinal metaplasia in the study group were significantly lower than those in the control group (P ＜ 0.05).The total effective rate of the study group was 90.91％,which was higher than75.61％ of the control group (P ＜ 0.05).Conclusions The effect of Wei Kangling in treating precancerous lesions of CAG is significant,especially for the histological changes of inflammation and intestinal metaplasia.

Objective To explore the evidence,urinary biomarkers,and partial mechanisms of hypercoagulability in the pathogenesis of IgA vasculitis(IgAV).Methods Differential expression of proteins in the urine of 10 healthy children and 10 children with IgAV was screened using high-performance liquid chromatography-tandem mass spectrometry,followed by Reactome pathway analysis.Protein-protein interaction(PPI)network analysis was conducted using STRING and Cytoscape software.In the validation cohort,15 healthy children and 25 children with IgAV were included,and the expression levels of differential urinary proteins were verified using enzyme-linked immunosorbent assay.Results A total of 772 differential proteins were identified between the IgAV group and the control group,with 768 upregulated and 4 downregulated.Reactome pathway enrichment results showed that neutrophil degranulation,platelet activation,and hemostasis pathways were involved in the pathogenesis of IgAV.Among the differential proteins,macrophage migration inhibitory factor(MIF)played a significant role in neutrophil degranulation and hemostasis,while thrombin was a key protein in platelet activation and hemostasis pathways.PPI analysis indicated that thrombin directly interacted with several proteins involved in inflammatory responses,and these interactions involved MIF.Validation results showed that compared to healthy children,children with IgAV had significantly higher urine thrombin/creatinine and urine MIF/creatinine levels(P<0.05).Conclusions Thrombin contributes to the pathogenesis of IgAV through interactions with inflammatory factors.Urinary thrombin and MIF can serve as biomarkers reflecting the hypercoagulable and inflammatory states in children with IgAV.
