ABSTRACT
The incidence of augmented renal clearance (ARC) in intensive care patients (ICU) is exceptionally high, and these patients are often co-morbid with infection. The occurrence of ARC will significantly increase the clearance rate of antibiotics, making it difficult for conventional doses to reach effective therapeutic concentrations and affect the patient's anti-infective treatment effect and prognosis. It can be seen that it is crucial to formulate a reasonable dosing regimen for ICU patients with ARC. Regrettably, few reports in China about the adjustment strategy of antibiotic dosing regimens for ARC patients. Therefore, this article reviews the domestic and foreign literature for reference to provide evidence for medical personnel to adjust the dose of antibacterial drugs for such patients.
ABSTRACT
With the development of technology and instruments, more and more giant liver tumors have been resected under laparoscopy. Compared with traditional approach hepatectomy, anterior hepatectomy is more suitable for laparoscopic resection of huge liver tumors, and it is also more in line with the " tumor-free principle" when it is used in the resection of liver malignant tumors. Our team summarized the experiences and lessons of laparoscopic hepatectomy and communicated with domestic and foreign experts to form a set of single center standardized process of laparoscopic anterior right hepatectomy, which is summarized as follows.
ABSTRACT
Objective:To study the survival outcomes in patients with Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma (HCC) treated with sorafenib combined with transcatheter arterial chemoembolization (TACE) versus sorafenib alone.Methods:The data of 92 patients with BCLC stage C HCC at Tianjin Medical University Cancer Institute& Hospital from January 2008 to December 2015 were retrospectively studied. There were 82 males and 10 females. The average age was 56.3 years. Classified according to whether there were vascular invasion and/or distant metastasis, patients were divided into the vascular invasion group ( n=24), the metastasis group ( n=48), and the vascular invasion combined with metastasis group ( n=20). All patients were treated with sorafenib, but some patients received combined treatment with TACE. The survival data of these patients on follow-up was collected. The Kaplan-Meier method was used for survival analysis, and the survival rates were compared by the log-rank test. Univariate and multivariate Cox analyses were used to determine the prognostic factors of patients’ survival. Results:There were no significant differences in the baseline clinical data among the three groups (all P>0.05). Multivariate Cox regression analysis showed that pre-treatment alpha fetal protein >20 μg/L ( HR=1.90, 95% CI: 1.13-3.12), alkaline phosphatase >125 U/L ( HR=1.60, 95% CI: 1.03-2.49) and sorafenib alone ( HR=2.11, 95% CI: 1.23-3.54) were independent risk factors of survival for these patients. There were no significant differences in the cumulative survival rates among the three groups ( P>0.05). In the vascular invasion group, the cumulative survival rates of patients treated with combined sorafenib and TACE ( n=4) were significantly higher than those treated with sorafenib alone ( n=20) ( P<0.05). Conclusion:Compared with sorafenib alone, sorafenib combined with TACE resulted in better prognosis for patients with BCLC stage C HCC. Subgroup analysis showed that patients with vascular invasion had significantly better survival treated with combined sorafenib and TACE than sorafenib alone.
ABSTRACT
Objective@#To investigate the clinical efficacy of radical resection for stage T3 gallbladder cancer and prognostic factors.@*Methods@#The retrospective case-control study was conducted. The clinico-pathological data of 87 patients with T3 gallbladder cancer who were admitted to Tianjin Medical University Cancer Institute and Hospital from January 2005 to June 2016 were collected. There were 44 males and 43 females, aged 29-79 years, with a median age of 61 years. According to the different preoperative pathological classification and intraoperative exploration of gallbladder cancer, corresponding surgeries were performed. Observation indicators: (1) surgical and postoperative conditions; (2) clinical efficacy of stage T3 gallbladder cancer and prognostic factors analysis; (3) clinical efficacy of stage T3 gallbladder adenocarcinoma and prognostic factors analysis; (4) clinical efficacy of stage T3 gallbladder adenosquamous carcinoma and prognostic factors analysis. Follow-up by outpatient examination or telephone interview was performed to detect the postoperative survival of patients up to June 2018. Measurement data with skewed distribution were represented as M (range), and count data were described as absolute numbers. Survival curve, survival time and survival rate were drawn and calculated by the Kaplan-Meier method. Survival analysis was performed by the Log-rank test. Univariate analysis was performed using the Log-rank test and multivariate analysis using the COX proportional hazard model.@*Results@#(1) Surgical and postoperative conditions: all the 87 patients underwent radical resection of gallbladder cancer, including 29 cases of hepatic wedge resection and 58 cases of extended hepatectomy. Of the 87 patients, 42 underwent standard lymph node dissection and 45 underwent enlarged lymph node dissection. There were 27 cases receiving extrahepatic bile duct reconstruction. The postoperative pathological results of 87 patients showed that 64 were diagnosed with gallbladder adenocarcinoma and 23 were diagnosed with gallbladder adenosquamous carcinoma. There were 59 cases comorbid with liver invasion and 3 cases comorbid with vascular invasion. The marginal histopathological examination showed negative margin in 63 cases and positive margin in 24 cases. The degree of tumor differentiation: there were 23 patients with highly differentiated tumor and 64 with poorly differentiated tumor. Of the 87 patients, 43 received postoperative adjuvant therapy and 44 didn′t receive adjuvant therapy. (2) Clinical efficacy of stage T3 gallbladder cancer and prognostic factors analysis. ① All the 87 patients were followed up for 1.8-128.0 months, with a median follow-up time of 26.3 months. All the 87 patients had survived for 1.1-82.7 months, with a median time of 20.1 months. The 2-year overall survival rate of patients was 59.8%, and the 2-year disease-free survival rate was 49.4%. ② Univariate analysis showed that preoperative alkaline phosphatase (ALP) level, tumor diameter, pathological type of tumor, lymph node metastasis, and range of hepatectomy were associated factors for the postoperative 2-year overall survival rate of patients (χ2=5.451, 4.900, 8.256, 4.419, 5.858, P<0.05), and pathological type of tumor, lymph node metastasis, and range of hepatectomy were associated factors for the postoperative 2-year disease-free survival rate of patients (χ2=5.828, 6.968, 4.077, P<0.05). Multivariate analysis showed that preoperative ALP level, tumor diameter, and lymph node metastasis were independent factors influencing the postoperative 2-year overall survival rate of patients [hazard ratio (HR)=2.539, 2.619, 2.201, 95% confidence interval (CI) : 1.174-5.491, 1.209-5.673, 1.104-4.391, P<0.05)]; pathological type of tumor and lymph node metastasis were independent factors influencing the postoperative 2-year disease-free survival rate of patients (HR=2.254, 2.296, 95%CI: 1.170-4.344, 1.206-4.374, P<0.05). ③ Survival analysis: pathological type of tumor was an associated factor for the postoperative 2-year overall survival rate and 2-year disease-free survival rate of patients. Of the 87 patients with T3 gallbladder cancer, there was no significant difference in the postoperative 2-year overall survival rate between the 64 patients with gallbladder adenocarcinoma and 23 with gallbladder adenosquamous carcinoma (68.8% vs. 34.8%, χ2=8.256, P>0.05), but a significant difference in the postoperative 2-year disease-free survival rate between them (56.3% vs. 30.4%, χ2=5.828, P<0.05). (3) Clinical efficacy of stage T3 gallbladder adenocarcinoma and prognostic factors analysis. ① Sixty-four patients with gallbladder adenocarcinoma had the median survival time of 23.1 months, with a range from 3.2 to 82.7 months. The postoperative 2-year overall survival rate was 68.8%, and the postoperative 2-year disease-free survival rate was 56.3%. ② For the 64 patients with T3 stage gallbladder adenocarcinoma, univariate analysis showed that preoperative CA19-9 level and range of lymph node dissection were associated factors for the postoperative 2-year overall survival rate (χ2=4.012, 8.837, P<0.05). The range of lymph node dissection was an associated factor for the postoperative 2-year disease-free survival rate (χ2=6.361, P<0.05). Multivariate analysis showed that range of lymph node dissection was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate (HR=0.244, 0.382, 95%CI: 0.088-0.674, 0.176-0.831, P<0.05). ③ Survival analysis: range of lymph node dissection was an associated factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients. Of the 64 patients with T3 stage gallbladder adenocarcinoma, the postoperative 2-year overall survival rate and disease-free survival rate of patients undergoing enlarged lymph node dissection were 84.8% and 69.7%, versus 51.6% and 41.9% of the patients undergoing standard lymph node dissection (χ2=8.837, 6.361, P<0.05). (4)Clinical efficacy of stage T3 gallbladder adenosquamous carcinoma and prognostic factors analysis. ① Twenty-three patients with gallbladder adenosquamous carcinoma had the median survival time of 13.2 months, with a range from 1.1 to 70.3 months. The postoperative 2-year overall survival rate was 34.8%, and the postoperative 2-year disease-free survival rate was 30.4%. ② For the 23 patients with T3 stage gallbladder adenosquamous carcinoma, univariate analysis showed that preoperative ALP level, lymph node metastasis, range of hepatectomy, and extrahepatic bile duct reconstruction were associated factors for the postoperative 2-year overall survival rate of patients (χ2=5.288, 4.574, 12.960, 4.106, P<0.05). The lymph node metastasis and range of hepatectomy were associated factors for the postoperative 2-year disease-free survival rate of patients (χ2=7.364, 10.582, P<0.05). Multivariate analysis showed that range of hepatectomy was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate (HR=0.102, 0.153, 95%CI: 0.012-0.880, 0.033-0.718, P<0.05). ③ Survival analysis: range of hepatectomy was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients. Of the 23 patients with T3 stage gallbladder adenosquamous carcinoma, the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients undergoing extended hepatectomy were 87.5% and 75.0%, versus 6.7% and 6.7% of the patients undergoing hepatic wedge resection (χ2=12.960, 10.528, P<0.05).@*Conclusions@#Lymph node metastasis is an independent factor influencing the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with T3 stage gallbladder cancer. The range of lymph node dissection is an independent factor for the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with stage T3 gallbladder adenocarcinoma. Range of hepatectomy is an independent factor for the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with stage T3 gallbladder adenosquamous carcinoma. Patients with gallbladder adenocarcinoma should undergo enlarged lymph node dissection, and patients with gallbladder adenosquamous carcinoma need to undergo extended hepatectomy.

ABSTRACT
Objective To analyze the activity of paraoxonase (PON1) and explore the relationship of PON1 and oxidative stress with systemic inflammation response in the acute exacerbation phase and stationary phase in patients with chronic obstructive pulmonary disease (COPD). Methods Serum PON1 activity was measured by phenylacetate in 38 patients with COPD and 30 healthy people. The activity of glutathione peroxidase (GSH-Px) was detected by improved Hafeman method. Total antioxidant capacity (TAC) was measured by eolorimetry and malondialdehyde (MDA) level was measured by thiobarbituric acid colouration method. The interleukin-6 (IL-6) and interleukin-8 (IL-8) levels were detected by radioimmunoassay. The level of C-reactive protein (CRP) was measured by immune turbidimetry. Results In the acute exacerbation phase, the activity of serum PON1 was significantly lower in COPD group than in control group [(98.03±42.40)×103U/L vs. (136.00±60. 50)×103U/L, t=4.962, P<0.01], and it was negatively related to the IL-8 level (r= - 0. 589, P<0.01) and positively related to FEV1% (r= 0. 434, P<0. 05). The activity of GSH-Px was negatively related to the IL-6 level (r=-0. 362, P< 0. 05). In the stationary phase of COPD group, the activity of serum PON1 had no statistical difference compared with control group[(131.50±53.65))×103U/L vs. (136. 00±60.50)×103U/ L, t=2. 457, P>0. 053, and it was negatively related to the IL-8 level (r=-0. 563, P<0.05). Conclusions Serum PON1 activity is significantly decreased in acute exacerbation phase of COPD group compared with control group and it is positively related to FEV1%. The oxidative stress is closely related to systemic inflammation response in patients with acute exacerbation of COPD.
