Objective To analyze the characteristic of twenty-item premature behavioral neurological assessment,and to assess the risk factors of neonatal behavioral neurological assessment(NBNA) in premature infants. Methods Total two hundred and seventy-four premature infants hospitalized in Guangzhou Children's Hospital were assessed with the NBNA after correcting age 40 weeks,premature infants were divided into two groups:normal group (n =221 ) and abnormal group (n =53) according to NBNA. The birth history, mother pregnancy situation, the disease during neonatal period and results in hospital were reviewed,and the risk factors of NBNA in premature infants were assessed. Results There were significant differences in gestational age, birth weight, head circumference, body height, Apgar score, resuscitation time, hospitalization time and total gastrointestinal nutrition time between the two groups( P < 0. 05 ). The incidences of superfoetation,hyaline membrane disease, hemorrhagic and hypoxic brain injury, severe infection, hyperbilirubinemia, hypoglycemia and chronic lung disease were different between the two groups( P < 0. 05 ). There were no differences in gender, antenatal hormone use, anaemia, hypotension and evoked potential abnormality (P >0. 05 ). Multivariate logistic regression analysis showed that the risk factors of NBNA score in premature infants would include low Apgar score, low birth weight, hyaline membrane disease, hemorrhagic and hypoxic brain injury, severe infection, hyperbilirubinemia, hypoglycemia and chronic lung disease. Conclusion Although the premature infants corrected age 40 weeks,but the capability and initiative muscular tension are still lower than term infant. Low Apgar score, low birth weight, hyaline membrane disease, hemorrhagic and hypoxic brain injury ,severe infection ,hyperbilirubinemia,hypoglycemia and chronic lung disease are important risk factors related to premature behavioral neurological assessment.

There are 13 members of the Let -7 miRNAs family which is regarded as tumor suppressor gene, locating in nine different chromosome loci. Lin28 acts as negative regulatory factor of miRNA biological recurrence. By selectively blocking the processing synthesis of the Let-7 miRNAs family, Lin28 block the inhibition effect of miRNA of proto-oncogenes and interact with RNA helicase to enhance gene translation at the same time. By not quite clear mechanism, an up-regulation of Let-7 inhibits the expression and function of Lin28. In more and more studies of human tumor, Lin28/Let-7 axsis was proved to be important significance of the tumor's occurrence and development. In this paper, we research briefly the recent progress of the molecular mechanism and related influence factors of ILin28/Let-7 axsis.

Objective To investigate the effect of minimally invasive surgery in patients with midge-upper advanced gastric cancer (AGC). Methods 167 patients with middle-upper AGC underwent total gastrectomy+D2 lymph node dissection from January 2009 to December 2013 were enrolled in the study and divided into laparoscopic assisted total gastrectomy (LATG) group (n = 57) and open total gastrectomy (OTG) group (n = 110). Baseline data, operative, postoperative data and follow-up result were compared between the two groups. Results There were no significant differences in baseline data between the two groups (P > 0.05); The intraoperative blood loss and incision length in LATG group were significantly lower than that in OTG group (P < 0.05). There were no significant differences in operation time, ratio of intraoperative blood transfusion, distance between the upper margin and the tumor, the number of lymph node dissection between two groups (P > 0.05); Postoperative first aerofluxus time, ecovery liquid diet time, postoperative hospitalization days and VAS score of pain in 3 d after operation in LATG group were significantly lower than that in OTG group (P < 0.05). There was no significant differences in incidences of postoperative complication between two groups (P > 0.05); There was no patient dying within 30 d after surgery.The median follow-up time was 38.2 months (1~58 months). Postoperative 1, 3 year overall survival rates in LATG group and OTG group were 87.7% and 83.6%, 71.9% and 64.5%, and there were no significant differences between the two groups (P > 0.05). Conclusion For patients with middle-upper AGC, LATG+D2 lymph node dissection has lots of advantages including less intraoperative blood loss, shorter incision, faster postoperative recovery, shorter hospital stay and so on, which is safe and effective, and their short-and long-term results are satisfactory.
