RESUMEN
Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.
RESUMEN
OBJECTIVE:To observe the effects of Gegenqinlian colon positioning tablet(GGQLJC)on colon tissue PPAR-γ, NF-κB p65 protein expressions of model rabbits with damp-heat type ulcerative colitis(UC). METHODS:56 rabbits were random-ly divided into normal group(normal saline),model group(normal saline),sulfasalazine tablet(SASP)group(positive control, 0.300 g/kg),Gegenqinlian tablet (GGQL) group (0.225 g/kg) and GGQLJC high-dose,medium-dose,low-dose groups (1.036, 0.518,0.259 g/kg),8 in each group. Except for normal group,rabbits in other groups were cultured for damp-heat-type UC mod-el,intragastrically administrated in the second day of last administration,once a day,for 14 d. Disease activity index(DAI),co-lonic mucosal damage index (CMDI),histological damage (TDI) were scored;colon,spleen and thymus indexes were deter-mined;PPAR-γ,NF-κB p65 protein expressions in colon tissue were detected. RESULTS:Compared with normal group,DAI, CMDI,TDI scores and spleen index,colon index,NF-κB p65 protein level in colon tissue in model group were significantly in-creased(P<0.01);thymus index,PPAR-γprotein level in colon tissue were significantly reduced(P<0.01). Compared with mod-el group,above-mentioned indexes in each administration group were significantly improved (P<0.05 or P<0.01). Compared with GGQL group,DAI and TDI scores,spleen index,colon index,NF-κB p65 protein level in colon tissue in SASP group, GGQLJC high-dose,medium-dose groups were significantly decreased (P<0.05);PPAR-γ protein level in colon tissue in SASP group,GGQLJC high-dose,medium-dose groups were significantly increased (P<0.05 or P<0.01). CONCLUSIONS:GGQLJC has certain improvement effects on model rabbits with damp-heat type UC,which is superior to GGQL. The mechanism may be re-lated to increasing PPAR-γprotein level and decreasing NF-κB p65 protein level in colon tissue.
