Objective To analyze the effect of different postoperative nutrition:enteral nutrition( EN) and parenteral nutrition( PN) in patients with colorectal cancer. Methods 84 patients with colorectal cancer were collected in this study from Jan. 2012 to Jan. 2014, and they were divided into the EN group (43 cases) and the PN group (41 cases). They were given EN or PN after operation. The nutritional parameters such as ALB, TF and PA were detected before surgery and 7 days after operation, Observe the adverse reaction, time of gastroin-testinal function recovery, infection and costs after operation. Results There was no statistical difference (P>0. 05) in the nutritional pa-rameters and rate of adverse reaction between the two groups. The rate of infection in EN group was lower than that in PN group(P<0. 01), and the time of gastrointestinal function recovery was shorter in EN group compared with that in PN group (P<0. 01). Conclusion EN is better in recovery of gastrointestinal function, and there is less complication compared to PN. EN have clinical application value for patients with gastrointestinal cancer.

Results Bil-iogenic chronic pancreatitis was found in 47 patients,of which 17 patients with APBDJ. The mean (SD) common channel was (19. 3±7. 2) mm in length ( range 11~40 mm) . Conclusion APBDJ may be the important reason of BCP among Chinese patients.

Objective To explore the relationship of professional stress,social support and somatic symptoms of sub-health status of Ningbo normal senior school teachers. Methods 128 normal senior school teachers were selected and investigated by professional stress scale,social support scale and somatic symptoms of sub-health status scale, and canonical correlation analysis was used. Results The canonical correlation coefficient were 0.563, 0.471( P <0.01) with the existence of social support variable. The somatic symptoms of sub-health status would be greater with the rise of their professional stress and the decline of their social support. The canonical correlation coefficient was 0.497( P <0.01) with the elimination of social support variable. The factor loading of "examination pressure","professional burden" and "career expectation" in canonical variable ξ add to 0.801,0.855,0.726 respectively. The factor loading of "feeling of fatigue","sleep disorders" in canonical variable η add to 0.774,0.859 respectively. Conclusion The social support have adjustment function between the professional stress and somatic symptoms of sub-health status.

To investigate the expression change of BDNF in lamina II of spinal cord from partial deafferented cats, L6 segmentsof spinal cord from 20 adult male cats (5 normal cats, 15 unilateral L6 spared roots cats allowed to survive 3 d, 6 d and 12 d re-spectively) were stained with immunohistochemical technique. The results showed: BDNF positive products were mainly dis-tributed in nerve terminals, varicosities and few neurons of spinal cord lamina II in normal cat. After operation, the density ofpositive nerve terminals and varicosities began to decrease on the third day, reached the lowest level on the 6th day and recoveredto normal level on the 12th day on operated side. But the number of BDNF neurons showed no obvious change. The authors sug-gest that the decreased density of BDNF positive products in lamina II on the 3rd and 6th day was related with the degenerationof the nerve fibers and varicosities after section of the adjacent dorsal roots. On the 12th day, the remaining L6 dorsal roots un-derwent collateral sprouting compensatoryly and reestablished functional connection with target neurons. Therefore, BDNF maybe involved in the normal physiological function and the plasticity of spinal cord after damage.

Objective To evaluate left ventricular function in patients with acute myocardial infarction and to investigate the clinical value by two-dimensional strain imaging of ultrasound.Methods Study population was consisted of 28 patients with acute myocardial infarction of wall anterior and 30 healthy subjects.Images were recorded from the left ventricular the apical 4-chamber view,apical 3-chamber view,apical 2-chamber view respectively.Two-dimensional strain and strain rate were measured in the left ventricular segments using two-dimensional strain software.We analyzed that relationship between two-dimensional the global peak systolic strain,global strain rate and left ventricular end systolic volume(LVESV),left ventricular end diastolic volume(LVEDV),wall motion score index(WMSI),left ventricular ejection fraction(LVEF).Results ①Infarct segments in myocardial infarction group showed significant reduction of peak systolic strain as compared with normal group(P

Objective To express P38 of Schistosoma japonicum in Escherichia coli BL21 and develop the monoclonal antibodies (McAb) against rSjP38. Methods The recombinant plasmid pET32(a)-P38 was transformed into E.coli BL21(DE3). 1 mmol/L IPTG (isopropyl-beta D-thiogalactopyranoside) was used to induce the expression of the recombinant rSjP38. The rSjP38 was soluble in supernatant after sonication and further purified by His-Ni chromatography. BALB/c mice were immunized with the purified rSjP38 and hybridomas were generated with traditional technique. McAbs were screened by ELISA with limited dilution. The subtype and specificity of McAb were identified by kit and Western blot respectively. Results Eight hybridoma cell lines secreting monoclonal antibodies to rSjP38 were obtained. The subtype of all the 8 McAbs are IgG1. Western blotting showed that the 8 McAbs reacted strongly and specifically with native antigen (P38) of Schistosoma japonicum. Conclusions Eight hybridoma cell lines secreting highly specific McAbs against P38 have been established.
