The main problems in the promotion and application of TCM lie in insufficient investment, lagging behind of construction of prevention and control system, insufficient professionals and ineffective heritance of practical technique. Conclusion In order to tackle these problems, relevant laws and regulations should be implemented;information management system with TCM features should be improved;construction of diversified technological innovation system should be reinforced, practical and strong technology should be promoted;construction of TCM prevention and control system for chronic diseases should be perfected.

Objective To investigate the impact of aging and vascular endothelial function on arterial stiff- ness in patients with isolated systolic hypertension.Methods Patients with isolated systolic hypertension (ISH,n=75)age-matched healthy subjects(n=30)and young healthy subjects(n=50)were submitted to deter- mination of aortic pulse wave velocity(baPWV)and vascular endothelial function evaluated by flow-mediated dila- tion(FMD).Results baPWV was progresively decreased(ISH:2459.2?436.8 vs elderly healthy:2097.2? 315.7 vs young healthy:1619.7?214.2 cm/s,P

Objective The aim of this study was to evaluate the optimal time for decompression in a 24-hour lasting porcine model.Methods After baseline data were recorded,24 pigs were randomly allocated into three groups as follows:one SAP-alone group,and two SAP + ACS groups (decompression at 6 and 12 hours,respectively).We used a N2 pneumoperitoneum to increase the intra-abdominal pressure to 25 mmHg and retrograde intra-ductal infusion of sodium taurocholate to induce severe acute pancreatitis (SAP).Systemic hemodynamic profiles,urine output,systemic oxygenation,and serum biochemical parameters of the animals were obtained.Results After induction of ACS,the hemodynamics and oxygenation of the study animals deteriorated significantly.The survival time of the 12-hour group was significantly shortened (P =0.008 vs.6 hours).Early decompression (6 h) restored systemic hemodynamics,oxygenation,organ function,and inflammatory intensity to a level comparable to that of the SAP-alone group.In contrast,animals in 12-hour group developed more severe hemodynamic suppression,oxygenation and organ dysfunction and inflammatory process.For instance,the cardiac output levels in the three groups were 2.70 ±0.50 for the SAP group,2.75 ±0.48 for the 6 hour-group and 2.19 ±0.43 for the 12 hour-group.Conclusion Early decompression could significantly reduce the mortality in a porcine model of SAP incorporating ACS,and also improve systemic hemodynamics,organ function and inflammatory intensity.

Objective:To investigate the pathogenic distribution of benign infantile convulsions with mild gastroenteritis(BICE)and explore the relevance of serum cytokines and BICE.Methods:Eighty BICE infants admitted in Inner Mongolia Maternal and Child Health Hospital from January 2017 to December 2019 were selected as BICE group, and 80 mild gastroenteritis infants without convulsion attack were selected as control group during the same period.Fluorometric real-time PCR was used to detect the pathogen of enterovirus.Serum cytokines including interleukin(IL)-6, tumor necrosis factor(TNF)-α, IL-8 and soluble interleukin-2 receptor(SIL-2R)were detected by using chemiluminescence method.The relevance of frequency and duration of convulsion in infants with BICE and the indicators above were analyzed.Results:Rotavirus infection was the main cause of BICE during the study period in this region.Among 80 cases in the BICE group, rotavirus positive infants accounted for 38.8%(31/80) and norovirus positive infants accounted for 10.0%(8/80). The levels of IL-6, IL-8 and SIL-2R in the BICE group were prominently higher than those in the control group( P<0.05); the difference of TNF-α level between two groups had no statistical significance( P>0.05). The levels of IL-6, TNF -α, IL-8, SIL-2R in the group with convulsion attack times ≥ 2 and convulsion duration ≥5 min were higher than those in the group with convulsion attack times<2 and convulsion duration<5 min( P<0.05). The frequency and duration of convulsions were positively correlated with the levels of IL-6, TNF -α, IL-8 and SIL-2R( P<0.05). Conclusion:Rotavirus is the main pathogen of BICE in this region.There is immunologic imbalance in children with BICE, especially the changes of IL-6 and SIL-2R levels, which may provide effective cytological and experimental data evidence for judging progression and prognosis of the disease.

The deubiquitinating enzyme ubiquitin specific peptidase 15 (USP15) is regarded as a regulator of TGFβ signaling pathway. This process depends on Smad7, the inhibitory factor of the TGFβ signal, and type I TGFβ receptor (TβR-I), one of the receptors of TGFβ. The expression level of USP15 seems to play vital roles in the pathogenesis of many neoplasms, but so far there has been no report about USP15 in psoriasis. In this study, immunohistochemical staining of USP15, TβR-I and Smad7 was performed in 30 paraffin-embedded psoriasis specimens and 10 normal specimens to investigate the expression of USP15, TβR-I and Smad7 in psoriasis and to explore the relevance among them. And USP15 small interfering RNA (USP15 siRNA) was used to transfect Hacat cells to detect the mRNA expression of TβR-I and Smad7. Of 30 cases of psoriasis in active stage, 28, 24 and 26 cases were positive for USP15, TβR-I and Smad7 staining, respectively. The positive rates of USP15 and Smad7 were significantly higher in psoriasis specimens than in normal skin specimens (44.1%±26.0% vs. 6.1%±6.6%, 47.2%±27.1% vs. 6.6%±7.1%), and positive rate of TβR-I (20.3%±22.2%) in psoriasis was lower than that in normal skin specimens (46.7%±18.2%). There was a significant positive correlation between USP15 and Smad7 expression, and significant negative correlations between USP15 and TβR-expression, an I d between TβR- and Smad7 expression I in psoriasis. After transfection of USP15 siRNA in Hacat cells, the expression of TβR-mRNA was up I -regulated and that of Smad7 was down-regulated. It is concluded that USP15 may play a role in the pathogenesis of psoriasis through regulating the TβR-I/Smad7 pathway and there may be other cell signaling pathways interacting with USP15 to take part in the development of psoriasis.
