Objective To explore influence of thoracic duct ligation on lipid metabolism after esophagectomy. Methods Seventy-four patients with esophageal cancer received esophagectomy were divided into two groups by their thoracic duct ligation, 39 in ligation group and 35 in non-ligation group. All the patients were fed with nutrients through nasal-duodenal tube placed during operation from the 1 st day to the 8th day after surgery, and started taking liquid diet on the 6th day. Blood specimens were collected from the patients on the 1st day after admission, the 9th day, one month and three months after surgery,respectively for biochemical analysis,including determinations of total cholesterol(TC),triglyeeride(TG),high-density lipoprotein-cholesterol ( HDL-C) and low-density lipoprotein-cholesterol ( LDL-C) . Databetween the two groups were compared with statistical analysis. Results No significant difference in plasma levels of TC, TG and HDI.-C was found between the two groups at varied time points. Plasma level of LDL-C in the ligation group significantly decreased on the 9th day after surgery, as compared with that in the nonligation group ( P < 0. 05), and went down to the lowest level one month after surgery. Conclusions Chylomicron was blocked to enter blood stream and production of LDL-C decreased by thoracic duct ligation,which affect lipid absorption and metabolism leading to poor early nutrition in patients with esophagealsurgery due to slower establishment of collateral circulation.

Aim To investigate the role of chemokine-like factor 1 ( CKLF1 ) in SH-SY5 Y cell migration and its molecular regulatory mechanism. Methods SH-SY5Y cells were stimulated with CKLF1 for 0. 5 h, 2 h, 8 h and 24 h, respectively. The migration distance and the percentage of migration cells were recorded by CELLocate analysis. The phosphorylation of focal ad-hesion kinase ( FAK) at Tyr-397 site was detected by Western blot analysis. By chemotaxis assays, we con-firmed the chemotaxis of CKLF1. Furthermore, FAK inhibitor PF-573228 and PLCγ inhibitor U73122 were used for the research of molecular regulatory mecha-nisms involved. Results CKLF1 promoted cell migra-tion and induced a strong increase in the phosphoryla-tion level of FAK-pY397 , which were significantly at-tenuated by the presence of U73122 ( a specific inhibi-tor for PLCγ) . In addition, the chemotaxis of CKLF1 was obviously blocked by the FAK inhibitor PF-573228 . Conclusion CKLF1 induces SH-SY5 Y cell migration via PLCγ/FAK signaling pathway.

Objective To explore the risk factors of hyperbilirubinemia in late preterm infants. Methods Clinical data of 211 cases of late preterm infants with hyperbilirubinemia and 246 cases of late preterm infants without hyperbilirubinemia were retro-spectively analyzed between 2011 and 2012. The risk factors of hyperbilirubinemia were filtered. Results Twenty-seven cases of late premature infants with hyperbilirubinemia were severe. Hospital stay less than 3 days, birth asphyxia history, small for gestatio-nal age, head hematoma, delivery injury, hypoalbuminemia, polycythemia, infection, hemolytic disease, feeding intolerance, and fe-tal excretion delay were associated with hyperbilirubinemia (P<0.05). Rural origin, pregnancy-induced hypertension syndrome and premature rupture of membrane were also associated with hyperbilirubinemia (P<0.05). Multivariate logistic regression analysis showed the history of birth asphyxia , fetal excretion delay, hypoalbuminemia, pregnancy-induced hypertension syndrome were risk factors of hyperbilirubinemia in late preterm infants (OR=2.35-4.05). Pregnancy-induced hypertension syndrome and hemolytic dis-ease were risk factors of severe hyperbilirubinemia in late preterm infants (OR=5.74, 73.64). Conclusions Neonatal asphyxia, fetal excretion delay, hypoalbuminemia and pregnancy-induced hypertension syndrome are risk factors of hyperbilirubinemia in late pre-term infants. Strengthening the management of pregnancy-induced hypertension syndrome and the treatment of newborn hemolytic disease can reduce the occurrence of severe hyperbilirubinemia in late preterm infants.

Metastasis contributes to the poor prognosis of hepatocellular carcinoma (HCC). However, the mechanism through which a primary HCC cell develops into a metastatic phenotype is not well understood. The purpose of this study was to examine the correlation between metadherin (MTDH)/astrocyte elevated gene-1 (AEG-1) expression in HCC cell lines of different metastatic potentials and such metastatic phenotypes as orientation chemotaxis and adhesion. MTDH/AEG-1 expression was detected by RT-PCR and western blotting in HCC cell lines (HepG2, Huh7, Sk-HEP-1, MHCC-97H). Distribution of MTDH/AEG-1 was observed by immunofluorescence staining and confocal laser scanning microscopy. The abilities of orientation chemotaxis and adhesion and the index of interaction between HCC cell lines and microvascular endothelial cell lines (MVECs, including HUVECs and HPMECs) were measured by chemotaxis assay and adhesion assay, respectively. The results showed that MTDH/AEG-1 protein expression was significantly higher in high metastatic potential cancer cell lines (Sk-HEP-1, MHCC-97H) than in low metastatic potential cell lines (HepG2, Huh7) (P<0.05). The MTDH/AEG-1 protein was localized in the perinuclear region of HCC cells. Furthermore, the abilities of orientation chemotaxis and adhesion of HCC cells to HPMECs were increased as compared with those of HCC cells to HUVECs (P<0.05). The abilities of orientation chemotaxis and adhesion were much stronger in Sk-HEP-1 and MHCC-97H cells with MTDH/AEG-1 highly expressed than in HepG2 and Huh7 cells with MTDH/AEG-1 lowly expressed (P<0.05). These results suggested that the expression of MTDH/AEG-1 gene in HCC cell lines of different metastatic potentials was closely positively related to the abilities of orientation chemotaxis and adhesion of HCC cells. It was deduced that MTDH/AEG-1 might play a pivotal role in the lung-specific metastasis of HCC, which may be mediated through orientation chemotaxis and adhesion abilities of HCC cells. MTDH/AEG-1 may serve as a potential therapeutic target for HCC.

Objective To investigate the effect of propofol on the learning and memory function in neonatal rats under hypoxic conditions. Methods Eighty-four 7-day-old SD rats were randomly divided into 6 groups (n = 14 each): propofol + 18% oxygen (propofol-hypoxia, group PH), propofol + air (group PA), propofol +100% oxygen (propofol-oxygen, group PO), 0.9% normal saline (NS) + 18% oxygen (group CH), NS + air (group CA), NS + 100% oxygen (group CO). The rats received injection of intraperitoneal propofol 50 mg/kg or NS 5.0 ml/kg once a day for 7 consecutive days and they were exposed to 18% oxygen, air or 100% oxygen at the end of each injection. SaO2 and respiratory rate (RR) were monitored and recorded after administration. The rats were returned to the cage after recovery of the righting reflex. Six rats in each group were sacrificed 24 h after the 7th injection, and the brain tissues were taken to observe the apoptosis in hippocampal neurons. Morris water maze test was used to test the learning and memory function 2 weeks after administration in the other rats. Results RR was significantly lower and the escape latency at T1.2 longer in group PO than in group CO (P < 0.05). RR and SaO2 were significantly decreased, apoptotic index was increased, the escape latency was prolonged and the frequency of crossing the original platform was reduced in group PA compared with group CA, and in group PH compared with group CH (P < 0.05). Compared with group PO, SaO2 was significantly decreased, apoptotic index was increased, the escape latency was prolonged and the frequency of crosing the original platform was reduced in group PA (P < 0.05). Conclusion Propofol induces apoptosis in hippocampal neurons and decreases the learning and memory function in neonatal rats under hypoxic conditions.
