RESUMEN
Liver injury remains a significant global health problem and has a variety of causes, including oxidative stress (OS), inflammation, and apoptosis of liver cells. There is currently no curative therapy for this disorder. Sanwei Ganjiang Prescription (SWGJP), derived from traditional Chinese medicine (TCM), has shown its effectiveness in long-term liver damage therapy, although the underlying molecular mechanisms are still not fully understood. To explore the underlining mechanisms of action for SWGJP in liver injury from a holistic view, in the present study, a systems pharmacology approach was developed, which involved drug target identification and multilevel data integration analysis. Using a comprehensive systems approach, we identified 43 candidate compounds in SWGJP and 408 corresponding potential targets. We further deciphered the mechanisms of SWGJP in treating liver injury, including compound-target network analysis, target-function network analysis, and integrated pathways analysis. We deduced that SWGJP may protect hepatocytes through several functional modules involved in liver injury integrated-pathway, such as Nrf2-dependent anti-oxidative stress module. Notably, systems pharmacology provides an alternative way to investigate the complex action mode of TCM.

Objective To summarize the clinical experience and effect analysis of liver transplantation from donation after citizen’s death. Methods Clinical data of 76 donors and 78 recipients of liver transplantation from donation after citizen’s death completed in Liver Transplantation Center of West China Hospital,Sichuan University from March 2012 to November 2015 were analyzed retrospectively.The functional recovery of early allografts in liver transplant recipients was observed and the risk factors causing early allograft dysfunction (EAD)were analyzed.In addition,long﹣term survival of allografts and recipient as well as complications was observed. Results The incidence of postoperative EAD was 36%(28 /78)in 78 recipients.High total bilirubin (TB)and long cold ischemia time constituted the risk factors of EAD. Survival rate of the recipients was 92% (72 /78)during perioperation,and 6 cases died,of which 4 cases died of primary graft dysfunction,1 case of upper gastrointestinal hemorrhage and 1 case of pulmonary infection.Postoperative abdominal infection occurred in 5 cases,with biliary stricture in 3 cases and vascular thrombosis in 2 cases.One case died,and the rest were improved after corresponding treatment.The 1﹣year survival rate of the recipients was 84.2% and 2﹣year survival rate was 80% after operation. Conclusions Liver transplantation from donation after citizen’s death realizes favorable short and long﹣term effects,which can be regarded as a good source of donor livers.Important measures such as controlling the preoperative quality of donor liver and shortening the cold ischemia time can improve the clinical effect.
RESUMEN
Objective To evaluate the value of fMRI guided brain surgery for the lesions in or around Broca's area.Methods Forty-three patients with lesions in or adjacent to the Broca's area were studied.fMRI imaging was obtained by BOLD technique with the tasks of reciting.Fiber tract imaging of white matter was obtained by DTI technique.All functional imaging and anatomic imaging were transferred to neuronavigation system.The technique of direct cortical stimulation was used to validate the language cortex in fMRI.The lesions were resected in microscope.Results Broca's area activation was detected in 38 cases..The distance between the fMRI peak and direct cortical stimulation was rated as overlapping (<1 cm diatance) in 25 cases and neighbouring (<2 cm diatance) in 11 cases.Total lesion resection was achieved in 17 cases, subtotal resection in 14 cases, and partial resection in 12 cases.Postoperative neurological functions were improved in 8 cases, unchanged in 31 cases, and temporary worsen in 4 cases.Conclusions The identification of the Broca's area by reciting task in fMRI is sensitive and precise.The fMRI is helpful to decrease the side effect injury in the brain surgery for the lesions in or around the Broca's area.
