Objective To study the impact of antiviral therapy on patients with postoperative intrahepatic recurrence of hepatitis B related hepatocellular carcinoma (HCC).Methods According to the inclusion and exclusion criteria,65 patients with HCC who were managed in our hospital from January 2004 to December 2011 for intrahepatic recurrence and had indications for antiviral treatment were included into this study.The patients were divided into two groups ; the antiviral and the control groups.Relevant data between these two groups such as cumulative survival after recurrence,Child-Pugh grade,HBV-DNA,HBeAg,AFP at the time of recurrence and 6 months later were studied.An analysis on multiple-factors was carried for survival after recurrence at 2 years.Results When compared with the control group,the antiviral group had better cumulative survival in all the cases and in the TACE cases (P ＜ 0.05 respectively).The cumulative survival in the RFA cases was not significantly different between the two groups (P ＞ 0.05).A comparison was carried out in patients who received antiviral therapy which was combined with one or more other therapies (TACE,RFA,reoperation):(a) antiviral therapy only (8 patients) ; (b) combined with one therapy (22 patients) ; (c) combined with two therapies (10 patients) ; (d) combined with three therapies (2 patients).All P values of a:b,a:c,a:d,b:c,b:d were less than 0.05.The blood HBV-DNA of the two groups was significantly different at the time 6 months after recurrence (P ＜ 0.05).The results of multivariate analysis showed the 2-year survival was significantly correlated with recurrent tumor size,primary tumor class,antiviral therapy or not after recurrence,presence of absence of cirrhosis.All P values were less than 0.05.Conclusions Antiviral therapy had remarkable clinical impact on HCC patients with postoperative intrahepatic recurrence and with indication for antiviral treatment.Patients had better prognosis if antiviral therapy was combined with one or more other therapies.

Objective To explore the effects of timing of enteral nutrition (EN) in the severe acute pancreatitis (SAP).Methods The rabbit model of SAP was constructed,and 40 experimental rabbits were divided randomly into the experimental group (20 rabbits) and the control group(20 rabbits).(1) The parenteral nutrition (PN) was administered to rabbits in the experimental group,and then EN was administered after bowel sound restoration.(2) EN was administered to the rabbits in the control group at hour 12 after PN.The values of TNF-α,IL-6 and IL-8 on post-modeling day 1,3 and 7 and intra-abdominal pressures at hour 1 before EN and on post-modeling day 1 and 3 were respectively examined.The experimental animals were sacrificed on post-modeling day 7 and 10.The expression of nuclear factor-kappa B (NF-κB) was detected by immunohistochemistry and bacteria from mesenteric lymph nodes were cultured.The measurement data with normal distribution were presented as (x) ± s.The trend comparison between groups and pairwise comparison were analyzed using the repeated measures ANOVA and t test.Results The 40 rabbit models of SAP were constructed successfully.(1) The results of serum test showed that the values of TNF-α,IL-6 and IL-8 in the experimental group on post-modeling day 1,3and 7 were (6.9 ±2.1)ng/L,(5.9 ± 1.8) ng/L,(5.3 ± 1.8) ng/L and (109 ± 17) ng/L,(96 ± 16) ng/L,(83 ± 17)ng/L and (89 ±20)ng/L,(78 ±21)ng/L,(70 ± 19)ng/L,respectively.The values of TNF-α,IL-6 and IL-8 in the control group on post-modeling day 1,3 and 7 were (7.4 ± 1.5) ng/L,(7.1 ± 1.6) ng/L (6.8 ±1.7) ng/L and (101 ± 19) ng/L,(98 ± 18) ng/L,(93 ±20) ng/L and (91 ± 14) ng/L,(91 ± 16) ng/L,(83 ±19)ng/L,respectively.There were significant differences in the changing trends of TNF-α and IL-6 between the 2 groups (F =7.947,19.386,P ＜ 0.05),with no significant difference in the changing trend of IL-8 between the 2 groups (F =2.756,P ＞ 0.05).(2)The intra-abdominal pressures in the experimental group at hour 1 before EEN and on post-modeling day 1 and 3 were (3.5 ± 1.6) cmH2O (1 cmH2O =0.098 kPa),(4.3 ± 1.7) cmH2Oand (3.6 ± 1.8) cmH2O,which were significantly different from (4.9 ± 1.9) cmH2O,(5.7 ± 2.2) cmH2O and (4.5 ± 1.6)cmH2O in the control group (F =7.042,P ＜0.05).(3) The expression of NF-κB in the tissues of pancreas was localized mainly in the cell nucleus.The expression of NF-κB in the experimental group on postmodeling day 7 was 5.0 ± 2.7,which was significantly different from 7.0 ± 2.9 in the control group (t =2.236,P ＜ 0.05).(4) The amount of bacteria culture from mesenteric lymph nodes in the experimental group on postmodeling day 7 and 10 were (4.7 ±0.9) × 103 cfu/g and (4.1 ±0.7) × 103 cfu/g,which were significantly different from (5.5 ± 1.0) × 103 cfu/g and (4.6 ± 0.7) × 103 cfu/g in the control group (t =2.382,2.126,P ＜0.05).Conclusion The selective timing of EN can effectively improve the recovery of rabbits with SAP,and the efficacy of EN administering based on the recovery of bowel function may be better than immediate EN administering.

Objective To observe the therapeutic effect of Shenmai injection on rats with acute edematous pancreatitis (AEP) and its mechanism.Methods The model of AEP in rats was induced by intraperitoneal injection of caerulein every one hour for 7 times.One hour after last injection,intravenous Shenmai injection (5 ml · kg-1 · d-1) was given to rats in Shenmai injection treatment (SI) group,while same amount of normal saline was given to rats in control (AEP) group.One hour and 1,3,5,7 d after AEP induction,the blood was taken,and the method of double antibody sandwich enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of amylase,platelet activating factor (PAF),vascular endothelial growth factor (VEGF).The rats were sacrificed at 7 and 14 d,and pancreatic tissue samples were harvested.RT-PCR and Western Blot were used to determine the expression of NF-κB mRNA and protein,and normal pancreatic tissue samples were used as control.The positive expression of CD31 in pancreatic tissue was determined by immunohistochemical method to calculate microvascular density (MVD).Results The serum levels of amylase and PAF in both groups were increased and gradually decreased 3 days later,while the decrement in SI group was greater than that of AEP group.At the 5th day after AEP induction,the serum levels of amylase in SI group and AEP group were (4569 ± 158),(5056 ± 198) U/L,and the serum levels of PAF were (25.30 ± 4.76),(36.06 ± 5.57)μg/L,and the difference between the two groups was statistically significant (P ＜ 0.05).The serum levels of VEGF were increased 1 d after AEP induction,and the increase in SI group was greater than that of AEP group 3 d later,and the serum levels of VEGF were (139.78 ±24.30),(118.51 ±21.70)pg/ml at 5th day,and the difference between the two groups was statistically significant (P ＜ 0.05).The expression levels of NF-κB mRNA and protein of pancreatic tissue in SI group were O.834 ±0.031 and 0.49±0.24,and MVD was 6.41 ± 1.14,while the corresponding values in AEP group were 1.000 ± 0.059,0.93 ± 0.45,3.62 ± 0.89,and the difference between the two groups was statistically significant (P ＜ 0.05 or P ＜ 0.01).Conclusions In the course of acute pancreatitis,Shenmai injection has the therapeutic effects of promoting new angiogenesis,improving the microcirculation,reducing the inflammatory cascade.

Objective To explore the clinical significance of expression of DcR3/TR6 gene in the tissue of cardiac cancer and its correlation with survivin gene expression, Methods Two-step immnaohistochemistry technology was adopted to detect the expression of TR6 and survivin gene in 66 cases of cardiac cancer, none of the patients received prior chemotherapy. Results The positive expression rate of TR6 and survivin genes in cardiac cancer was 54.5% and 62.1% , respectively. The expression of TR6 was correlated with histology type,clinical stage and lymph node metastasis of cardiac cancer ( P<0.05 ). The positive expression rate of TR6 in cases that cardiac cancer with survivin expressed was significant higher than those without surviving expressed (χ2=15.145, P<0.01 ). Conclusions The expres-sion of TR6 and survivin can be regarded as valuable indicators for the diagnosis and prognosis of cardiac cancer.

Objective To identify the disease burden and indirect economic burden caused by lung cancer in Kunshan City, Jiangsu Province, from 1981 to 2020. Methods The incidence and death cases of lung cancer were obtained from cancer registry and death cause monitoring data. The disability adjusted life years (DALY) was used as the evaluation index for burden posed by lung cancer on health, and the indirect economic burden was calculated by a human capital method. Results From 1981 to 2020, a total of 9272 deaths due to lung cancer were reported in Kunshan, of which 7106 were males and 2166 were females. The DALY caused by lung cancer in the whole population were 3.81, 4.14, 4.38, and 9.46 in 1981–1990, 1991–2000, 2001–2010, and 2011–2020, respectively. The indirect economic burden caused by lung cancer was 10.515, 141.657, 813.794, and 6659.149 million yuan. From 2011 to 2020, the ratios of years of life lost due to premature mortality to DALY in males, females, and the general population were 92.42%, 95.15%, and 93.60%, respectively. Conclusion The health burden and indirect economic burden for lung cancer are substantial in the Kunshan City. Moreover, age-specific DALY and indirect economic burden are not exactly symmetrical, suggesting that an effective control strategy to lower cost is urgently needed, especially for individuals aged 40-59.

Objective To investigate the effect of ursolic acid (UA) on the colorectal tumor and microenvironment in mice,and to provide a theoretical basis for the clinical application of UA.Methods The models of subcutaneous transplanted tumor of mouse CT26 cells was established.The models were divided into four groups:control group,tumor bearing group,tumor beating dimethyl sulfoxide (DMSO) group and tumor beating UA group.Tbe serum levels of interleukin-6 (IL-6) were detected by enzyme linked immunosorbent assay (ELISA).The number and percentage of myeloid-derived suppressor cell (MDSC) in the spleen of mice were analyzed by flow cytometry.The mRNA levels of IL-6 and signal transducer and activator of transcription 3 (STAT3) in tumor were examined by real-time quantitative polymerase chain reaction (RT-PCR).The protein levels of STAT3 and p-STAT3 in tumor were detected by Western blotting.Results The results showed that UA could significantly decrease the number of spleen MDSC.The accounts of spleen MDSC of tumor bearing UA group (249.60 ± 17.12) was lower than that of tumor beating DMSO group (366.40 ± 34.08),and the difference was statistically significant (P =0.021).The serum level of IL-6 in tumor bearing UA group [(46.40 ± 17.05) pg/ml] was decreased than that in tumor bearing DMSO group [(94.27 ±21.51) pg/ml],and the difference was statistically significant (P =0.012).The expression levels of IL-6 and STAT3 mRNA in tumor tissues of tumor bearing UA group (0.12 ±0.01,0.21 ±0.08) were lower than those of tumor bearing DMSO group (0.69 ± 0.14,0.79 ± 0.06),and the differences were statistically significant (P =0.008;P =0.003).The protein expression levels of STAT3 and p-STAT3 in tumor tissues of tumor bearing UA group (0.81 ±0.02,0.28 ±0.04) were lower than those of tumor bearing DMS0 group (0.98 ±0.02,0.91 ±0.22),and the differences were statistically significant (P =0.027;P =0.029).Conclusion UA may inhibit the activation of STAT3 signaling pathway and the amplification of MDSC in microenvironment by reducing IL-6,thus to enhance the function of immune-killing tumor cells to regulate tumor immune microenvironment and inhibit the immune escape of mouse colorectal cancer cells.
