Objective To observe the effects of DanShen on the growth of hepatocellular carcinoma in malignant obstructive jaundice in the SD rat model. Methods The model was established by vaccination of transplanting tumour in the porta hepatis with the walker-256 hepatocarcine line, and then obstruction was caused by the infiltration and metastasis of hepatocellular carcinoma. ② The SD rats were divided into four groups: the rats treated by 0.9% NS (n=12), the rats treated by Inosine + Vitamin C (n=20), the rats treated by DanShen (n=20) and the rats treated by 5-FU(n=20). ③ The liver function, morphological changes and the expression of PCNA VEGF and ICAM-1 in carcinoma and peri-carcinoma tissues, adjacent lobe (left-internal lobe) as well as lung tissues were observed after four experimental groups were successively treated by four medicines. ④ Statistical analysis was done to the experimental results. Results ① The growth of rats treated by DanShen injection showed that liver injury caused by malignant obstructive jaundice was significantly relieved compared with liver function and pathological morphological changes in other groups(P0.05); ③ The expression of PCNA VEGF and ICAM-1 in carcinoma, peri-carcinoma adjacent lobe (left-internal lobe) tissues as well as lung tissues were significantly downgraded in groups treated by DanShen injection compared with those in groups treated with 0.9%NS and Inosine combined with Vitamine C (P0.05). Conclusion DanShen injection not only has protective effects on liver injury caused by obstructive jaundice, but the medicine can inhibit the proliferation and growth of hepatocarcinoma, interfere with the vascularization of tumors, and prevent recurrence and metastasis of hepatocarcinoma.

Objective To study the expressions of Chemerin in hepatocellular carcinoma (HCC) and HCC cell lines,and to demonstrate the relationship between the expressions and prognosis.Methods The expressions of Chemerin protein in normal hepatocellular tissues,HCC and their paired tissues were detected by immunohistochemical staining of SABC; the expressions of Chemerin protein in HCC,cell lines and immortalized hepatocyte cell lines were detected by RT-PCR.Results The positive expression rates of Chemerin were 56.67％,90.00％,100％ in HCC,HCC cell line and normal hepatocellular tissues respectively,and the differences were significant (P＜0.05).The expressions of Chemerin mRNA in HCC paired tissues were higher than in HCC (P＜0.05).There was a higher expression of Chemerin mRNA in immortalized hepatocyte cell line LO2 ; but a lower expression in HCC cell lines.The expressions of Chemerin were related to lymph node metastasis,portal vein tumour thrombi,differentiation and TNM stage but not related to sex,age,tumour size,HBsAg and AFP.Conclusions Down-regulated expression of Chemerin may play an important role in the development,progression and metastasis of HCC.It may be a molecular marker for prognosis of HCC.

Objective To explore the effects of baicalin on the expression of ICAM-1 in lung injury induced by severe acute pancreatitis(SAP). Methods SAP model was induced by injection of 62mmol/L sodium taurocholate solution into biliopancreatic duct. A total of 72 SD rats were randomly divided into 3 groups: sham operation group, SAP group and SAP treated with BA group. Myeloperoxidase(MPO) activity in lung tissue was examined at 3, 6 and 12h. The expression of ICAM-1 in lung tissue was determined by immunohistochemical technique. The pathological changes of pancreas and lung tissue were examined under optical microscope.

Objective To analyze the distribution and antibiotic resistance of pathogens isolated from sputum in early postoperative patients after esophageal surgery, and investigate the risk factors of pulmonary infections after esophageal carcinoma and reasonable application of antibiotics during perioperative period.Methods The clinical data of 414 patients with esophageal carcinoma who were admitted to the Affiliated Hospital of Binzhou Medical University from January 2012 to June 2014 were retrospectively analyzed.The second generation cephalosporins were used as preventive antibiotics for the 181 patients between January and December 2012 and the third generation cephalosporins were used for the 233 patients between January 2013 and June 2014.Sputum samples were collected and inspected before operation and in the first three days after operation for observing distribution and antibiotic resistance of pathogens.The incidence of postoperative pulmonary infection was observed in the two kinds of patients.The risk factors closely related to the occurrence of postoperative pulmonary infections were analyzed.Comparison of rate and univariate analysis were done by chi-square test.Multivariate analysis was done with logistic regression.Results The positive rate of early post-operative sputum culture was 24.64％ (102/414), 32.04％ (58/181) in patients receiving the second generation cephalosporins and 18.88％ (44/233) in patients receiving the third generation cephalosporins, respectively, with a significant difference between the two generations of cephalosporins (x2 =9.502, P ＜ 0.05).A total of 131 strains of pathogens were isolated from early postoperative sputum samples including 12 strains of gram-positive bacteria and 119 strains of gram-negative bacteria.The top three bacteria were Klebsiella pneumoniae subsp pneumoniae (33 trains), Acinetobacter baumannii (20 strains) and Pseudomonas aeruginosa (19 strains).The resistance rate of gram-negative bacteria in early postoperative sputum samples to meropenem, ciprofloxacin and levofloxacin were 5.0％-25.0％, 2.6％-15.2％, 2.6％-20.0％, respectively.Among cephalosporins, the resistance rate to ceftriaxone, cefotaxime, cefepime, ceftazidime, cefuroxime and cefazolin were 10.3％-20.0％ , 5.3％-30.0％ , 12.8％-31.6％, 15.4％-42.1％ , 21.2％-55.0％ and 15.2％-60.0％, respectively.The overall postoperative pulmonary infection rate was 18.60％ (77/414).The pulmonary infection rate of patients receiving the second generation cephalosporins was 26.52％ (48/181), which was higher than 12.45％ (29/233) of patients receiving the third generation cephalosporins (x2=13.326, P ＜ 0.05).The results of univariate analysis showed that smoking, chronic obstructive pulmonary disease, application of the second generation cephalosporins during the perioperative period and early postoperative sputum culture positive were correlated with the postoperative pulmonary infection after esophageal carcinoma surgery (x2 =5.149, 22.765, 13.326, 159.092, P ＜ 0.05).Multivariate statistical analysis with logistic regression demonstrated that application of the third generation cephalosporins during the perioperative period was independent protective factor of postoperative pulmonary infection (OR =2.582, 95％ confidence interval: 1.331-5.009, P ＜ 0.05).Conclusions The pathogens from sputum in early postoperative period after esophageal surgery are complicated with gram-negative bacteria as the main pathogens especially Klebsiella pneumoniae subsp, pneumoniae, and different levels of antibiotic resistance are ubiquitous.The third generation cephalosporins can effectively prevent the postoperative pulmonary infection after esophageal carcinoma surgery.

Cell secreted sulfatase 2 is an endogenous sulphate esterase, which can hydrolyze the sulphate groups in extracellular matrix or on the chain of heparan sulphate on the outer surface of cell membrane, which can dissociate the growth factor bound to heparan sulphate proteoglycan, improve the local concentration of growth factor and activate the downstream signal. Sulfatase 2 is highly expressed in a variety of tumors, and the increased expression of sulfatase 2 in hepatocellular carcinoma is associated with poor prognosis. Sulfatase 2 can promote tumor progression by activating multiple signaling pathways in hepatocellular carcinoma cells. Inhibit the activity of hepatocellular carcinoma cell sulfatase 2, and then inhibit the proliferation, migration and tumorigenesis of hepatocellular carcinoma cells. In this paper, the research progress of sulfatase 2 and its role in the occurrence and development of hepatocellular carcinoma is summarized.
