Objective To explore the clinical value of intra-arterial thrombolytic therapy for hepatic artery thrombosis after liver transplantation. Methods Routine color doppler imaging (CDI) was used to detect hepatic artery thrombosis (HAT) after liver transplantation in 160 cases. Suspected patients were further confirmed by immediate angiography. Four cases of HAT were diagnosed and treated by intra-arterial thrombolysis. Two cases received repeatable transcatheter hepatic arterial thrombolysis with a low dose of urokinase. Results Hepatic artery recanalization was achieved in 3 cases. Among the 3 cases, multiple HAT occurred in 1 case, intra-arterial thrombolysis was successfully completed in the end. Two cases had intra-abdominal hemorrhage, which was cured by conservative treatment. One case received retransplantation because of interventional thrombolysis failure and intra-abdominal hemorrhage. Conclusion Intra-arterial thrombolytic therapy may be a promising method in the treatment of HAT. Transcatheter hepatic arterial thrombolysis shows a significant result.

Objective:Comparing the influence of colon cancer recurrence of laparoscopic and open operation to evaluate the safety and validity of operation.Methods:The cohort study includes 62 cases of laparoscopic and 83 cases of open colon cancer radical surgery from January 2010 to October 2012.The research aimed at comparing the effects of laparoscopic and open surgery for colon cancer recurrence by analyzing postoperative follow-up ending and GCC-mRNA & CEA.Results:There have no obvious differences in age,sex,BMI,tumor size,stage,grade,pathological types and resection range between laparoscopy and open group(P＞0.05).Postoperative 3-years recurrence of two groups have no difference (P＞0.05),but 1-year recurrence rate of laparoscopic was obviously lower than open operation (3.2％ vs 14.5％,P＜0.05).There have no obvious differences of postoperative overall survival rate and mortality(P＞0.05),but 1-year disease-free survival rate of laparoscopic group was obviously higher than laparotomy group (93.5％ vs 81.3％,P＜0.05).The postoperative GCC-mRNA and CEA positive rate of laparoscopic was significantly lower than laparotomy group.Univariable and Multivariable analysis reveals that laparoscopic colorectal cancer radical can obviously reduce the cancer recurrence within 1 year (P＜0.05).Addition,stage,aspirin and other amino acid drugs are independent risk factors of postoperative recurrence (P＜0.05).Conclusion:Laparoscopic colon cancer radical surgery is a safe and effective operation and can reduce short-term recurrence of colorectal cancer compared to open surgery.

Varied TCM constitutions in the patient of acute cerebral infarction were classifyed by using HLA - DQAl allehc gene to analyze hereditary susceptibility of constitution types and relation among constitution, syndrome and treatment. PCR-SSP technique was used for classification of Yin - deficiency Yang - deficiency, Qi - deficiency, phlegm - dampness and blood stasis constitution in 103 cases of acute cerebral infarction and HLA - DQAl allelic gene was used for gent classification in 99 cases of nomal constituion. Results indicated that HLA -DQA * 0501 gene type in Yin -deficiency constitution was significant higher than that of normal constitution CP

Objective To investigate the effect of Emodin on intracellular calcium concentration ([Ca~(2+)]i) and apoptosis of hepatic cells after simulated cold ischemia-reperfusion. Methods Glucose-oxygen deprivation, low temperature, subsequent reoxygenation and rewarming were used to induce ischemia-reperfusion injury model in cultured hepatic cells which were divided into 4 groups: control group and Emodin-treated group(100, 10 and apoptosis rate were determined by flow cytometry (FCM) respectively; the content of lactate dehydrogenase (LDH) in supernatant was tested. Results Intracellular calcium fluorescence intensity in Emodin-treated groups of high, medium and low density was 24.12±0.51, 26.35±1.34 and 39.12±1.94, respectively, which were significantly lower than 105.29±1.01 in control group(P<0.01). Apoptosis rate in Emodin-treated groups of high, (179.67±18.57)u/L in Emodin-treated groups of medium and high density respectively, which were significantly lower than (351.33±34.16)u/L in control group(P<0.01). Conclusion Emodin could reduce [Ca~(2+)]i and inhibit apoptosis of hepatic cells after simulated cold ischemia-reperfusion, thus protecting hepatic cells effectively.

Objective:To analyze the effects of microvascular invasion (MVI) and anatomical hepatectomy on early recurrence and survival of patients with hepatocellular carcinoma (HCC).Methods:The data of 246 patients with HCC admitted to 215 Hospital of Shaanxi Nuclear Industry, Chinese PLA General Hospital and Beijing Tsinghua Chang Gung Hospital from July 2008 to June 2019 were retrospectively analyzed, including 208 males and 38 females, aged (53.8±9.6) years. According to the occurrence of MVI, 246 patients were divided into the MVI group ( n=83) and control group ( n=163, without MVI). Hepatitis B virus (HBV) infection, preoperative alpha-fetoprotein (AFP), maximum tumor diameter, intraoperative blood loss were compared between the two groups. The recurrence-free survival and cumulative survival were compared between the two groups before and after the inverse probability weighted correction for propensity score. Results:The propensity score was calculated by logistic regression model. After inverse probability weighted correction, the virtual sample size was 247 cases (82 cases in MVI group and 165 cases in control group). The proportion of HBV infection, with a serum level of AFP > 200 μg/L, the maximum diameter of tumor and the intraoperative blood loss were higher in MVI group (all P<0.05). The risk of early recurrence in patients undergoing anatomical hepatectomy ( n=107) was lower than that in patients undergoing non-anatomical hepatectomy ( n=139) (univariate Cox regression analysis of HR=1.60, 95% CI: 1.06 to 2.42, P=0.020), but the overall survival was comparable (univariate Cox regression analysis of HR=1.66, 95% CI: 0.80 to 3.42, P=0.200). The recurrence-free survival (RFS) of MVI group was lower than that of the control group, and the postoperative cumulative survival rate was also lower before the inverse probability weighted correction of the tendency score. The RFS in MVI group was lower than that in control group after the tendency score was adjusted by inverse probability weighting ( HR=2.62, 95% CI: 1.61 to 4.27, P<0.001). There was no significant difference in the cumulative survival between the MVI and control group ( HR=2.09, 95% CI: 0.89 to 4.93, P=0.050). Conclusion:MVI is associated with early postoperative recurrence in patients with HCC, and the early recurrence rate after anatomical hepatectomy is lower than that after non-anatomical hepatectomy.
