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 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 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.

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

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 To study the clinical effect of psychological intervention combined with trimetazidine and bisoprolol in the treatment of left ventricular ejection fraction with heart failure. Methods 40 patients with heart failure were enrolled in this study. 40 patients were divided into control group and study group by digital randomization. There were 20 patients in each group and the patients in the control group.The patients were treated with trimetazidine and bisoprolol. The study group was treated with psychological intervention on the basis of the treatment. The clinical efficacy, adverse reactions, left ventricular ejection fraction and anxiety self-rating were analyzed (SAS), self-rating depression scale (SDS) score. Results The total effective rate of the clinical treatment group was 90.00％ higher than that of the control group (70.00％)P<0.05. There was no significant difference between the two groups in the adverse reaction. The mean left ventricular ejection fraction of the study group was (40.25 ± 5.24), which was significantly lower than that of the control group (43.92 ± 5.30). The scores of the study group were (50.26 ± 1.35) and (51.38 ± 2.61) respectively in SAS and SDS scores (54.36 ± 2.60), (56.98 ± 3.25) in the control group, (P<0.05). Conclusion The patients with left ventricular ejection fraction retention psychological failure in the application of trimetazidine, bisoprolol treatment based on the necessary psychological intervention, can effectively improve the patient's negative emotions, improve patient compliance, and then improve clinical efficacy, clinical significant application value.

Objective To explore the clinical effect of drug combination psychological intervention in colorectal cancer patients.MethodsRetrospective analysis of 60 cases surgical histopathology diagnosis of colorectal cancer patients with clinical diagnosis and treatment data from January 2014 to January 2016 in the Shaoxing Second Hospital, all patients were treated with surgery, including postoperative chemotherapy, hyperthermia treatment as the control group;In the control group based on supplemented by traditional Chinese medicine Fuzheng Xiao′ai Tang, psychological intervention for the observation group, each group of 30 cases.ResultsThe scores of quality of life and self-care ability of the two groups were significantly higher than those of the control group before and after treatment, and the scores of self-care ability were significantly higher in the observation group than in the control group (P<0.05) The levels of CEA, CA199 and CA242 were significantly lower than those of the control group before and after treatment, the level of tumor markers was significantly lower than that of the control group (P<0.05).The total effective rate was 73.33% in the observation group, which was significantly higher than that in the control group (43.33%, P<0.05).The observation group was significantly higher than the control group (P<0.05) Mental health was significantly lower than the control group,(P<0.05).ConclusionChinese medicine Fuzheng Xiao′ai Tang combined with chemotherapy and psychological intervention in the treatment of colorectal cancer after the effect is significant and safe.
