Using brartemicin as the leading compound, fifteen novel trehalose derivatives were designed and synthesized, and the structures were determined by 11H NMR, MS and element analysis. Inhibitory effects of the target compounds on the proliferation of A549, HepG2 and HUVEC cells were detectec by MTT assay. The abilities of adhesion, invasion and migration of A549 and HepG2 cells inhibited by the synthesized compounds were evaluated through Matrigel experiment and Transwell assay. The results showed that, the target compounds had no significant cytotoxicity (compared with the control, P>0.05) to A549, HepG2 and HUVEC cells at the dose range of 1-32 µmol.L-1. At the above dose range, the inhibitory effects of A549 cells adhesion, invasion and migration and HepG2 cells adhesion and invasion by compounds 79 and 82 are better than brartemicin.

Objective To compare the reliability of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and APACHE Ⅲ to estimate mortality of critical patients in abdominal surgery. Methods Two hundred and sixty-one critical patients in abdominal surgery were included in this study. The clinical data of the first day in ICU were collected and evaluated with both APACHE Ⅱand APACHE Ⅲ prognostic systems and statistical analysis were performed. Probability of survival (Ps) was compared with actual mortality. Results The scores of APACHE Ⅱ and APACHE Ⅲ of death group were significantly higher than those of survival group respectively (P

OBJECTIVE:To investigate the preventive use of antibacterials in patients undergoing cesarean section in our hospital.METHODS:A total of 360 medical records of patients undergoing cesarean section were randomly sampled in 2006(30 cases per month)for an analysis of the correlation between choice of antibacterials,combination rate and course of treatment etc and curative effects.RESULTS:Of the 360 cases,86.8% used second and third generation cephalosporins,6.3% fourth generation cephalosporin(cefepime),3.8% cephradine.CONCLUSION:No positive correlation was noted between choice of antibacterials and course of treatment and the curative effects in the prevention of postoperative infection.

Urethral stricture is one of the common complications after hypospadias repair,and it is related with the blood supply of materials used in urethra formation.The more severe and proximal hypospadias is,the higher possibility of stricture is.The patients with urethral stricture have the symptoms of stranguria and urinary retention,and they usually need re-surgery.The repair with well vascularized flap can decrease the occurrence of urethral stricture after hypospadias repair.

Objective The hippocampus has been used in Chinese medicine for a long time.Although it has the anti-decrepitude,anti-fatigue and anti-tumor effect,the molecular mechanism is not yet known.PI4-K,the first protein kinase in the PI pathway,should be the target molecular for drug screening.Methods We prepared antigen protein IOV-PI4-K through inside-out ghost,then the antibody-antigen reaction between IOV-PI4-K and its antibody A6D was tested by ELISA.Results Two different function groups,which could increase or decrease the binding affinity of PI4-K to its antibody,were screened out from the extracts of hippocampus.This fact indicated that there might be two different components to up-regulate or down-regulate the activity of PI4-K respectively.Conclusion Derivatives of the components could be developed into anti-tumor or anti-decrepitude drugs.Meanwhile,a new way for performing drug screen through ELISA was established.

Objective To evaluate the effect of the assessment of intervention of rational use and special initiative of antineoplastic Chinese patent medicine in tumor ward of Nantong First People’s Hospital (hereinafter referred to as “the hospital”); To facilitate the rational use of medicine in clinical setting. Methods Medical records of discharged patients in April and October 2015 were collected, and various types of irrational use of Chinese patent medicine was analyzed and put into statistical analysis. Results The proportion of medical records of irrational use of Chinese patent medicine declined from 39.45% to 18.49%; the percent of irrational prescription order sheet declined from 11.49%to 3.45%;the differences of variors irrational medicine use before and after the intervention were statistically significant. Conclusion The status of the rational use of antineoplastic Chinese patent medicine in tumor ward is improved after half-year special intervention and correction initiative.

Pancreatic cancer is one of the malignant tumor with a high case fatality rate.Because the disease onset symptoms is not obvious,and the disease develops quickly, the malignant degree is high, so it is difficult to do early diagnosis in clinical, leading to poor treatment effect.In recent years, more and more of the discovery and application of pancreatic tumor markers provide a new way for early diagnosis of pancreatic cancer.This article is a review of the current status of the research on the tumor markers associated with the early diagnosis of pancreatic cancer.

In recent years, the morbidity rate of pediatric asthma showed a rising trend.The typical symptom of recurrent wheezing(＞ 3 times/year) in infants is the starting point for the diagnosis of asthma in children and may be the early clinical manifestation of asthma.Chronic airway inflammation, which inducing airway hyperresponsiveness is the main pathophysiology of recurrent episodes of wheezing.Monitoring of fractional exhaled nitric oxide (FeNO) is a simple, fast, effective, and noninvasive marker of airway inflammation in asthma.The concentration of nitric oxide can effectively reflect the airway inflammation and is positively correlated with the severity of airway inflammation.Monitoring airway inflammation is helpful to diagnose and treat the asthmatic children, and for predicting asthma exacerbation, guiding and monitoring the asthma.Thus, this review will discuss FeNO measurements among wheezing infants and asthmatic that have been identified in large-scale studies recently.
