The relationship between 3 polymorphisms sites [interleulin-4 (IL-4), IL-4 receptor (IL-4R) alpha chain and activation-induced cytidine deaminase (AICDA)] and adult allergic asthma in China was studied. By using case-control method, DNA and clinical data were obtained from allergic asthmatic patients and compared with those in the control subjects. The subjects were genotyped for the IL-4 C-589T promoter polymorphism, the IL-4R alpha chain Q576R and the AICDA C8408T by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The results showed that the IL-4 C-589T was not associated with adult allergic asthma in China. However, the IL-4R alpha chain 576R/R and AICDA 8408T/T frequency was significantly increased in allergic asthma group as compared with that in the control group [odd ratio (OR) = 3.797 and 9.127, respectively; P < 0.01)] and was correlated with the increased plasma total IgE. These data suggested that the IL-4R alpha chain 576R/R and AICDA 8408T/T genotypes confer genetic susceptibility to adult allergic asthma in China.

Objective To accurately judge the tumor-feeding artery is the most important basis for a successful treatment of hepatocellular carcinoma (HCC) with super-selective hepatic arterial chemoembo lization therapy. This study aims to assess the clinical value of cone-beam CT hepatic arteriography (CBCT-HA) in detecting tumor-feeding arteries during the performance of conventional transarterial chemoembo lization (TACE), and to compare the diagnostic effects between CBCT-HA and non-selective hepatic DSA. Methods Twenty-three consecutive patients with inoperable HCC were enrolled in this study. TACE was carried out in all patients. During the performance of TACE, the DSA-HA, CBCT-HA, Lipiodol-TACE and Lipiodol-CBCT were performed separately. The imaging materials, including DSA-HA and CBCT-HA, were analyzed by two experienced interventional physicians together to judge the tumor-feeding arteries. Statistic analysis was conducted by using chi square test. Results Tumor stain and lipiodol accumulation were regarded as the “gold standard” of the presence of tumor-feeding artery, based on which the tumor-feeding artery was confirmed in 75 lesions. DSA-HA demonstrated positive tumor-feeding artery in 40 lesions, among which true-positive tumor-feeding artery was seen in 32 and false-positive one in 8. CBCT-HA showed positive tumor-feeding artery in 72 lesions, which included true-positive tumor-feeding artery in 68 and false-positive one in 4. The sensitivity of CBCT-HA in judging tumor-feeding artery was 90.7% (68/75), which was much higher than that of DSA-HA (42.6%, 32/75), the difference was statistically significant(P<0.001). The positive predictive value of CBCT-HA in detecting tumor-feeding artery was also higher than that of DSA-HA (94.4% vs. 80.0%; P=0.040). Conclusion Cone-beam CT hepatic arteriography is obviously superior to DSA hepatic arteriography in identifying tumor-feeding arteries, which is very helpful in guiding super-selective TACE for HCC.

Objective The palliation of dysphagia in metastatic esophageal cancer remains a challenge ,and the optimal approach for this difficult clinical scenario is not clear .We therefore sought to define and determine the efficacy of various treatment options used at our institution for this condition .Methods Methods We reviewed a prospective database for all patients managed in an e-sophageal cancer referral centre over a 5-year period .All patients receiving palliation of malignant dysphagia were reviewed for de-mographics ,palliative treatment modalities ,complications ,and dysphagia scores (0= none to 4= complete) .The Wilcoxon signed rank test was used to determine significance (P<0 .05) .Results During 2005~2010 ,80 patients with inoperable esophageal cancer were treated for palliation of dysphagia .The primary treatment was radiotherapy in 66% ,metal stenting in 21% and radiotherapy combined with stent in 13% .Mean duration of treatment was 1 day in he stent group and 40 days in the radiotherapy group(P=0 . 001) .In patients treated initially by stenting ,dysphagia improved within 2 weeks of treatment in 82% of patients(dysphagia score of 0 or 1) .However ,18% of patients presented with recurrence of dysphagia at 10 weeks of treatment .In the radiotherapy group , the onset of palliation was slower ,with only 50% of patients palliated at 2 weeks(dysphagia score of 0 or 1) .However ,long-term palliation was more satisfactory ,with 90% of patients remaining palliated after 10 weeks of treatment .Conclusion In inoperable e-sophageal cancer at our centre ,radiation treatment provided durable long-term relief ,but came at a high price of a long wait time for initiation of treatment and a long lag time between initiation of treatment and relief of symptoms .On the other hand ,stenting pro-vided more rapid and effective early relief from symptoms ,but was affected by recurrence of dysphagia in the long-term .

Objective:To study the effects of docetaxel, cisplatin and fluorouracil (TPF) regimen simultaneous intensity modulated radiotherapy (IMRT) on immune function and survival prognosis of patients with advanced esophageal cancer.Methods:A total of 93 patients with advanced esophageal cancer were screened in Hebei Veterans General Hospital from June 2015 to December 2017, and were divided into two groups using randomized envelope method. The observation group (47 cases) was given synchronous TPF regimen and IMRT, and the control group (46 cases) was given synchronous PF regimen (cisplatin combined with fluorouracil) and IMRT. Esophageal barium meal, chest and upper abdominal CT were reviewed within 1 month after treatment to assess the short-term efficacy and compare the immune function of the two groups before and after treatment. Kaplan-Meier survival curve was plotted to evaluate the long-term efficacy based on overall survival (OS). The incidence of adverse reactions in the two groups was collected to evaluate their safety.Results:After treatment, the T cell subgroup CD8 + level of the observation group was higher than that of the control group [(33.55±4.46)% vs. (29.06±3.61)%, P<0.05], while CD3 + [(51.29±5.22)% vs. (56.04±6.10)%, P<0.05], CD4 + [(28.27±3.63)% vs. (30.35±3.52)%, P<0.05] and CD4 + /CD8 + (0.84±0.25 vs. 1.04±0.08, P<0.05) levels were lower than those of the control group. The effective rate of recent treatment in the observation group was 82.98% (39/47), while the effective rate in the control group was only 63.04% (29/46), with a statistically significant difference ( χ2=4.70, P=0.030). The median OS of the observation group was 25.3 months (95% CI: 17.9-26.1), and that of the control group was 18.2 months (95% CI: 14.4-25.5), with a statistically significant difference ( χ2=3.28, P=0.038). Adverse reactions during the follow-up period of the two groups of patients were mainly nausea/vomiting, fatigue, anorexia, hematological toxicity, esophagitis and pneumonia, etc., which were mostly grade 1-2, and disappeared after symptomatic treatment or termination of treatment. Compared with the control group, the incidence of nausea/vomiting (46.81% vs. 78.26%, χ2=9.80, P=0.002), anorexia (44.86% vs. 71.74%, χ2=6.99, P=0.008), leukopenia (36.96% vs. 73.91%, χ2=13.37, P<0.001) and esophagitis (61.70% vs. 82.61%, χ2=5.05, P=0.025) adverse reactions was lower in the observation group. Conclusion:TPF combined with IMRT has high efficacy and low adverse reactions, which can be used as an effective treatment to improve the survival prognosis of patients with advanced esophageal cancer.

Objective To investigate the effects of miRNAs-107 (miR-107) on pancreatic cancer proliferation,senescence and invasion.Methods MiR-107 expression levels in 3 pancreatic cancer cell lines PANC-1,ASPC-1,BXPC-3 and normal pancreatic HTERT-HPNE cells were studied by quantitative reverse transcription-polymerase chain reaction (qRT-PCR).PANC-1 cells were transfected with 50 nmol/L anti-miR-107 or negative control using Lipofectamine 2000.After transfection,the miR-107 expression was measured by qRT-PCR.Cell proliferation was tested by methylthiazol tetrazolium (MTT) assay.Cell senescence was detected by β-galactosidase staining.The expression levels of PCNA,P16INK4A and MMP2 were measured by qRT-PCR.Results Compared with the HTERT-HPNE cells,the expression level of miR-107 in 3 pancreatic cancer cell lines was significantly increased (P ＜ 0.01).After transfected with 50 nmol/L anti-miR-107,cell proliferation was inhibited,and cell senescence were increased in PANC-1 cells (P ＜ 0.05),and there was no obvious change in cell invasion.Compared with the HTERT-HPNE cells,after transfected with anti-miR-107,the PCNA expression was significantly decreased and P16INK4A was significantly increased,but expression of M MP2 didn't change significantly.Conclusions These results demonstrate that miR-107 promotes the proliferation and escapes cell senescence in PANC-1 cells by targeting PCNA and P16INK4A.But it has no obvious effects on cell invasion.Therefore,it may be a new target for the biologic therapy for pancreatic cancer.

Objective To explore the value of transcatheter arterial chemoembolization (TACE) combined with portal vein embolization (PVE) prior to laparoscopic right hemihepatectomy (LRH) in the treatment of large liver tumor.Methods A retrospective study was conducted based on the clinical data of 8 patients with large liver tumor undergoing PVE combined with TACE before scheduled LRH,with 4 cases receiving simultaneous TACE + PVE and the other 4 cases doing sequential TACE + PVE.Results The interval between TACE and PVE was 14-29 d in sequential group,and the interval between PVE and surgery was 13-30 d.Patients in simultaneous treatment group encountered more prominent elevation of transaminase after PVE and TACE,but they recovered to comparable levels with the sequential group before surgery.The average standard future liver remnant (sFLR) increased from 35.3％ ± 4.9％ to 48.7％ ± 5.1％ before surgery.LRH was performed sucessfully in all patients with no conversion and perioperative death.Complications occurred in 2 cases,including pulmonary infection and bile leakage.The median hospital stay was 36 days.All patients were survival in the 25 months median follow up time including 2 recurrence cases.Conclusions TACE combined with PVE prior to LRH in the treatment of large liver tumor is safe and feasible.

Objective:To evaluate the safety and clinical efficacy of transcatheter arterial chemoembolization (TACE) combined with portal vein embolization (PVE) and percutaneous microwave ablation liver partition with PVE for planned hepatectomy in patients with hepatocellular carcinoma (HCC) with insu-fficient remnant liver volume.Methods:The clinical data of 51 patients with initially unresectable HCC due to insufficient remnant liver volume admitted to Zhejiang Provincial Tongde Hospital and Zhejiang Provincial People’s Hospital from January 2014 to December 2021 were retrospectively analyzed, including 37 males and 14 females, aged (56.7±11.2) years old. Patients were divided into two groups according to the treatment prior to hepatectomy: percutaneous microwave ablation liver partition combined with PVE (AP group, n=12) and TACE with PVE (TP group, n=39). Patients who successfully underwent planned hepatectomy in the above two groups were marked as resectable AP group ( n=10) and the resectable TP group ( n=29), respectively. Clinical data including the waiting time for surgery and the incidence of complications were analyzed. Patients were followed up by telephone or outpatient review. Kaplan-Meier and log-rank analysis were used for survival comparison. Results:The FLR growth rate was higher in AP group [76.5% (65.3%, 81.6%)] than that in TP group [31.4% (28.2%, 41.9%), P<0.01]. The waiting time for planned hepatectomy in the resectable AP group was 12.0 (11.3, 14.5) d, shorter than that in the resec-table TP group [21.0 (15.0, 29.0) d, P<0.05]. The incidence of postoperative complications was higher in the resectable AP group than that in the resectable TP group [80.0% (8/10) vs. 27.6% (8/29), P<0.05]. There was one perioperative death in the resectable AP group. The survival rate after PVE was lower in AP group than that in TP group, and the survival rate after hepatectomy was also lower in the resectable AP group than that in the resectable TP group (all P<0.05). Conclusion:For HCC patients with insufficient FLR, TACE combined with PVE is a safe and effective method for enlargement of liver remnant, whereas percutaneous microwave ablation liver partition with PVE showed a poor prognosis, despite the higher rate of FLR enlargement and shortened the waiting time for planned hepatectomy.

Objective To study the safety and feasibility of laparoscopy combined with holmium laser in the treatment of chronic pancreatitis complicated with pancreatic ductal stones.Methods To compare the clinical data in patients who underwent laparoscopy combined with holmium laser (10 patients,group A) with those who underwent laparoscopy only (21 patients,group B) at Zhejiang Provincial People' s Hospital from January 2012 to August 2018.The operation time,intraoperative blood loss,intraoperative conversion rate,pancreatic ductal incision length,postoperative pancreatic fistula rate,length of postoperative hospital stay,residual stone rate and relief of postoperative abdominal pain rate of the two groups were documented and analyzed.Results Three of 31 patients were converted to open surgery.The remaining patients in the two groups were discharged home without any perioperative death.Group A and B were significant differences in the pancreatic ductal incision length (5.0±0.8 vs.6.5±1.0) cm,operation time (289.3±51.6 vs.349.5± 34.7) min,and postoperative hospital stay (8.0± 1.2 vs.10.2± 1.6) d between the two groups (P＜0.05).There were no significant differences in the intraoperative conversion to open rate,intraoperative blood loss,postoperative pancreatic fistula rate,residual stone rate and relief of postoperative abdominal pain rate between the two groups (P ＞ 0.05).Conclusions It was safe and feasible to treat chronic pancreatitis complicated with pancreatolithiasis by laparoscopy.Laparoscopy combined with holmium laser had the added advantages of easy access through the pancreaticojejunostomy,shorter operation time,and less intraoperative blood loss.
