Aim To explore the inhibitory effect of Euonymus alatus on hepatic fibrosis induced by carbon tetrachloride (CCl4) in mice and its mechanism. Methods Eighty C57BL/6 male mice were randomly divided into eight groups: normal group, CCl4model group, Euonymus alatus(EA) ethanol extracts groups in early stage(EAE), EA ethanol extracts groups in later stage(EAL),two drug groups with low/medium/high dose(EAE-L/M/H, EAL-L/M/H), with 10 mice in each group. Fibrosis model was established by injecting CCl4in peritoneal cavity,and the study lasted for 30 days. Different doses of drugs were given from 1 st day to 15 th day in EAE while from 16 th day to 30 th day in EAL,then all mice were sacrificed to for the observation of the morphological changes and collage-nous fiber by HE and Masson staining. Liver index, ALT,AST and TNF-α were tested by ELISA. The ex-pressions of α-SMA and CollagenⅠwere measured by immunohistochemistry and Western blot. Results Compared to normal group, liver index, ALT, AST, TNF-α, α-SMA and CollagenⅠ in EA groups were lower than those in model group in a dose-dependent manner(P<0.01 or P<0.05). Liver morphology and collagenous fiber in EAE and EAL were better than those in model group in a dose-dependent manner. The effect of EAE were superior to that of the EAL in HE, Masson, α-SMA, Collagen Ⅰ indexes(P <0.05). Conclusions Euonymus alatus may inhibit the process of hepatic fibrosis in mice with dose-effect de-pendence, and drug treatment in early stage performs better,which may be related to the decrease of TNF-α that affects the expression of α-SMA and Collagen Ⅰ.

OBJECTIVE:
To determine the diagnostic value of the expression of survivin mRNA in sputum samples and pleural effusions in lung cancer.
METHODS:
The sputum samples of 104 patients with lung cancer and 30 patients with chronic obstructive pulmonary disease (COPD), and the pleural effusion of 56 patients with lung cancer and 30 patients with tuberculosis pleural effusions were detected.Reverse transcription-polymerase chain reaction (RT-PCR) was performed to detect the survivin mRNA expression in the specimens. The results were compared with their cytological examinations.
RESULTS:
The sensitivity of the cytological examinations combined with the detection of survivin mRNA in sputum samples was higher than that of either cytological examination or survivin mRNA detection of sputum samples alone (P<0.01). The sensitivity of the diagnosis for lung cancer increased from 37.5% (sputum cytology alone) to 78.8% (sputum survivin mRNA detection combined with sputum cytology) (P<0.01), and the negative predictive value increased from 31.6% (sputum cytology alone) to 43.5% (sputum survivin mRNA detection combined with sputum cytology) (P<0.01). The sensitivity of the cytological examinations combined with the detection of survivin mRNA in pleural effusion samples was higher than that of cytological examination of pleural effusion samples alone (P<0.01). The sensitivity of the diagnosis for lung cancer increased from 42.9% (pleural effusion cytology alone) to 80.4% (pleural effusion survivin mRNA detection combined with cytology) (P<0.01), and the negative predictive value increased from 48.4% (pleural effusion cytology alone) to 77.8% (pleural effusion survivin mRNA detection combined with cytology) (P<0.01).
CONCLUSION
The detection of survivin mRNA from sputum samples and pleural effusions samples is a new diagnostic method for lung cancer.

OBJECTIVETo compare efficacy of different adjuvant chemotherapy regimens for stage II-III gastric cancer after D2 gastrectomy in Asian patients.
METHODSAssociated literatures were searched through electronic databases and hand-searching. Prospective randomized clinical trials (RCTs) comparing adjuvant chemotherapy after D2 gastrectomy with surgery alone were included in the study. Overall survival and disease-free survival were chosen as the endpoints. Relative hazard was analyzed by Bucher adjusted indirect comparison.
RESULTSTwo RCTs were selected, including comparison between S-1 versus surgery alone and comparison between XELOX versus surgery alone. There was no statistical difference in overall survival between the two regimens (HR=0.94, 95%CI:0.62-1.44, P=0.79). The recurrence risk of S-1 was slightly higher as compared to XELOX, but no statistical difference was found (HR=1.11, 95%CI:0.80-1.53, P=0.54).
CONCLUSIONThe adjuvant chemotherapy with S-1 is similar to XELOX for stage II-III gastric cancer after D2 gastrectomy in Asian patients.

Insulin-like growth factor binding-protein-7 (IGFBP7) was obtained from our previous colonic adenocarcinoma (CRC) and normal mucosa suppression subtraction hybridization (SSH) cDNA libraries. By RT-PCR and immunohistochemistry, we found that IGFBP7 was overexpressed in CRC tissue compared to normal tissue. However, our in vitro experiments performed in 10 CRC cell lines showed that IGFBP7 expressed only in SW480 and Caco2 cell lines, which implied an underlying reversible regulatory mechanism. Using methylation-specific PCR (MSP) and bisulfite sodium PCR (BSP), we found that its expression was associated with DNA hypomethylation of exon1. This was further supported by the in vitro study which showed restored IGFBP7 expression after demethylation agent 5-aza-2'-deoxycytidine treatment. Correlation analysis between IGFBP7 expression and prognosis indicated that overexpression of IGFBP7 in CRC tissue correlated with favourable survival. Investigation of the functional role of IGFBP7 through transfection studies showed that IGFBP7 protein could inhibit growth rate, decrease colony formation activity, and induce apoptosis in RKO and SW620 cells, suggesting it a potential tumor suppressor protein in colorectal carcinogenesis. In conclusion, our study clearly demonstrated that IGFBP7 plays a potential tumor suppressor role against colorectal carcinogenesis and its expression is associated with DNA hypomethylation of exon 1.

OBJECTIVETo study the effect of golden-hour body temperature bundle management strategy on admission temperature and clinical outcome in preterm infants with a gestational age of <34 weeks after birth.
METHODSThe preterm infants who were born in the delivery room of the West China Second University Hospital of Sichuan University and admitted to the department of neonatology of this hospital within 1 hour after birth from December 2015 to June 2016 and from January to May, 2017 were enrolled. The 173 preterm infants who were admitted from January to May, 2017 were enrolled as the intervention group and were given golden-hour body temperature bundle management. The 164 preterm infants who were admitted from December 2015 to June 2016 were enrolled as the control group and were given conventional body temperature management.
RESULTSThe intervention group had a significantly higher mean admission temperature than the control group (36.4±0.4°C vs 35.3±0.6°C; P<0.001). The incidence rate of hypothermia on admission in the intervention group was significantly lower than that in the control group (56.6% vs 97.6%; P<0.001). The intervention group had a significantly lower incidence rate of intracranial hemorrhage within one week after admission than the control group (15.0% vs 31.7%; P<0.05).
CONCLUSIONSGolden-hour body temperature bundle management for preterm infants within one hour after birth can reduce the incidence of hypothermia on admission and improve clinical outcome.

OBJECTIVETo investigate the effect of 5-FU (5-fluorouracil) on enriching cancer stem cells of HCC cell line BEL-7402 and the biological characteristics of enriched cells.
METHODSThe enriching concentration of 5-FU was determined by CCK-8 (cell counting kit-8). Flow Cytometry was used to determine the changes in cell cycle and positive expression ratio of surface marker CD56, CD54, EpCAM and CD133. The self-renewal and differentiation of positive cells were tested by colony formation assay, and were compared with the control group.
RESULTSEnriching concentration of 5-FU was determined as 10 μg/ml with 48 h incubation. After enrichment, G0/G1 phase cells increased from 57.50 %+/-0.98% to 68.70%+/-3.41% (P<0.05). Whereas S phase cells decreased from 40.26%+/-4.12% to 31.80%+/-4.15% (P<0.01); G2/M phase cells disappeared in experimental group, and was 5.80%+/-1.87% in control group (P<0.01). The proportion of the cell cycle changed with significant statistical differences. Meanwhile, positive rate of cell surface makers CD56, CD54, EpCAM and CD133 increased from 0.57%+/-0.12%, 8.10%+/-6.79%, 0.3%+/-0.01% and 3.20%+/-0.99% to 4.13%+/-0.06%, 50.08%+/-1.69%, 0.55%+/-0.07% and 10.51%+/-1.13%, respectively. The difference was significant (P<0.05). The colony forming ratio of CD56, CD54, EpCAM and CD133 negative cells and positive cells were 2.11%+/-0.21%, 3.32%+/-0.31%; 0.86%+/-0.101%, 2.40%+/-0.52 %; 7.19%+/-0.56%, 7.73%+/-0.71%; 2.70%+/-0.26%, 5.75%+/-0.81%, respectively, and significant differences were found between (P<0.05).
CONCLUSION5-fluorouracil enriched the cancer stem cell population in HCC cell line BEL-7402. CD56 and CD54 can be used as important surface markers in research of liver cancer stem cells.
