Objective To determine the brain natriuretic peptide(BNP) levels and the effects of endothelin receptor antagonist(ERA) on BNP levels in patients with tetralogy of Fallot(TOF) recently surgical repaired.Methods During January 2010 to January 2012,32 cases of TOF after surgical repaired in hospital were selected.There are 20 males and 12 females,Aged 4 years to 18 years [mean age (7.64 ± 3.75) years] in age.All patients underwent enhanced CT to evaluate the pulmonary vessels and left ventricular before surgery arrangements.As the surgeries done,the patients were grouped randomly as either A or B.All 14 patients in group A started to follow the recommended dosage of bosentan within 3 days after surgery.Meanwhile,all 18 in group B had not taken bosentan or any other ERAs since the surgeries.Both group was evaluated and examined with echocardiography and blood test at the 10th day after surgery.Results None of the patients died within 10 days after surgery.BNP levels of group A was significantly lower than of group B.Inotropic score of group A was markedly lower,too.However,although group A showed mildly advantages in tricuspid regurgitation,pulmonary regurgitation,ratio of RV/LV end-systolic dimension and liver functions,there was no statistically significant difference.Conclusion For patients with tetralogy of Fallot,early use of ERAs after surgical repaired could reduce the use of inotropic agents and significantly decrease the BNP levels when discharged.
3.Advances in therapies for unresectable hilar cholangiocarcinoma
International Journal of Surgery 2021;48(7):433-438
Hilar cholangiocarcinoma is the most common malignant tumor of the biliary tract. Surgical resection is the only radical treatment method at present. However, due to its insidious onset and high degree of malignancy, it is usually in the middle or late stage when first diagnosed, most patients have lost the chance of radical surgery and have a very poor prognosis. In recent years, with the continuous progress of medical technology, the optimization and different combination of treatment methods such as chemotherapy, radiotherapy, biliary drainage, photodynamic therapy, nano-knife ablation, intraluminal radiofrequency ablation, liver transplantation, targeted therapy and immunotherapy has significantly improved the prognosis of patients with unresectable hilar cholangiocarcinoma. Chemotherapy, radiotherapy, photodynamic therapy and intraluminal radiofrequency ablation on the basis of biliary drainage can prolong the time of biliary patency. Nano-knife ablation can maximize the elimination of tumor cells on the premise of protecting the structure of the ducts. Liver transplantation offers a possibly curative opportunity for patients with unresectable hilar cholangiocarcinoma. Targeted therapy and immunotherapy provide a breakthrough point for precision therapy and individualized therapy. Based on the literature and the clinical experience of our team, this paper discussed the therapeutic approaches for unresectable hilar cholangiocarcinoma and encountered problems, so as to provide reference for clinical treatment and related research.

OBJECTIVE:
To investigate the in vitro and in vivo anticancer efficacy of the immunotoxin DTATEGF against human NSCLC brain metastatic tumor PC9-BrM3 cell line.
METHODS:
The effect of the immunotoxin DTATEGF was tested for its ability to inhibit the proliferation of PC9-BrM3 cells in vitro by MTT assay. The cell cycle and the apoptosis of cells with 1 pmol/L DTATEGF were examined by flow cytometry. In vivo, 2 μg of DTATEGF or control Bickel3 was given intratumor to nude mice with established PC9-BrM3 xenografts on their hips, and tumor volumes were measured and tumor samples were investigated by immunchistochemistry SABC method. The microvessel density (MVD) was measured in each group.
RESULTS:
In vitro, DTATEGF killed PC9-BrM3 cells and showed an IC50 of 1 pmol/L. The apoptotic rate in the 1 pmol/L DTATEGF group was (64.0±0.5)% , significantly higher than that in the control group (1.5±0.4)% (P<0.01). The cell cycle was obviously inhibited by DTATEGF in a dose-dependent manner. The percentage of cells treated with 1 pmol/L DTATEGF in SubG0/G1 phase was (32.0±1.5)%, significantly higher than that in the control group (2.0±0.4)% (P<0.01). In vivo, DTATEGF significantly inhibited the growth of PC9-BrM3 hip tumors (P<0.05). The MVD of the DTATEGF group was (15.6±4.6)/mm2, significantly lower than that of the control group (31.2±5.4)/mm2 (P<0.01).
CONCLUSION
DTATEGF inhibits the growth of the PC9-BrM3 cell line and induces its apoptosis. It is highly efficacious against human metastatic NSCLC brain tumor and against neovascularization.

OBJECTIVE:
To investigate the in vitro and in vivo anticancer efficacy of the immunotoxin DTAT and DTATEGF against globlastoma multiforme.
METHODS:
The in vitro cytotoxicity of DTAT and DTATEGF was measured using MTT assay. In vivo studies were performed in which 18 nude mice were randomly divided into 3 groups and the glioma xenograft intracranial mouse model was constructed with U87-luc cell line of human glioma. Then 1 μg of DTAT, or DTATEGF, or a control protein Bickel3 was delivered intracranially by convection-enhanced delivery (CED) via an osmotic minipump. The brain tumor fluorescence signal intensity was investigated by bioluminescent imaging (BLI). Microvessel density (MVD) was measured by immunchistochemistry SABC method in each group.
RESULTS:
In vitro DTAT and DTATEGF were found highly potent against U87-luc cell line, with IC(50) <0.01 nmol/L and IC(50)<1 nmol/L, respectively. In vivo BLI monitoring of the control group showed progressively increasing luminescence, while in the two treatment groups, luminescence was reduced on day 8, and increased slowly (P<0.05). The MVD of DTAT (31.6±5.2)/mm(2) and DTATEGF (25.1±6.5)/mm(2) groups had significant difference with that of the control group (51.3±7.4) /mm(2) (P<0.01).
CONCLUSION
Both DTAT and DTATEGF have potential in clinical application against globlastoma multiforme because of their ability to target the tumor cells and neovasculature simultaneously.

Objective:To study the effect of sorafenib and prophylactic transarterial chemoembolization (TACE) for prevention of postoperative relapse in patients with liver cancer combined with microvascular invasion (MVI) after using radical hepatectomy.Methods:A retrospective analysis was performed on 137 cases that underwent radical hepatectomy at the First Affiliated Hospital of Zhengzhou University from August 2015 to January 2018. Clinical data of liver cancer patients with MVI were diagnosed by postoperative pathology. General data of the three groups were analyzed. Kaplan-Meier was used to calculate the tumor-free survival rate. COX proportional hazards-model was used to analyze the independent risk factors for postoperative recurrence of liver cancer with MVI recurrence. Counting data was compared by x 2 test between groups, and log-rank test was used to compare the tumor-free survival rates. Results:A, B, and C groups had 49, 36, and 52 cases, respectively. General clinicopathological data of the three groups were not statistically significant. The postoperative tumor-free survival rates at 1-, 2-, and 3-years were 71.4%, 51.0%, 38.8%, 86.1%, 75.0%, 66.7%, and 82.7%, 75.0%, and 59.6% respectively in A, B, and C groups. Multivariate Cox proportional-hazards regression model showed that patients' age ( HR = 0.622, P = 0.046), maximum tumor diameter ( HR = 1.661, P = 0.033), prophylactic TACE ( HR = 0.544, P = 0.019), and postoperative use of sorafenib ( HR = 0.419, 0.222, 0.791, P = 0.007) were independent risk factors for postoperative recurrence of liver cancer with MVI. Conclusion:Sorafenib or prophylactic TACE use can significantly reduce the recurrence rate within 3 years after radical surgery in patients with liver cancer who were confirmed to have MVI by postoperative pathology.
