Objective:To explore the feasibility and efficacy of short peptide enteral nutrition in preoperative bowel preparation for patients with gynecological laparoscopy.Methods:A total of 100 patients with gynecological laparoscopy were randomized into the trial group (n =50) and the control group (n =50) by using the random number table method.Patients in the study group received short peptide enteral nutrition for three days before operation without mechanical bowel preparation.Patients in the control group received traditional liguid diet and mechanical bowel preparation.The satisfaction of bowel preparation,postoperative anal exhaust time,hospitalization time and nutritionrelated parameters were compared between the two groups.Results:Doctor's satisfaction of bowel preparation in the study group was significantly higher than the control group (90％ vs 64％) (P ＜ 0.01).Postoperative anal exhaust time and hospitalization time were shorter in the control group (both P ＜ 0.05).The levels of postoperative albumin and hemoglobin in study group were significantly higher than the control group (bothP ＜ 0.05).Conclusion:Short peptide EN in preoperative bowel preparation of gynecological laparoscopy reveals a better efficacy and safety,a better recovery in postoperative intestinal function and nutritional status,and a shorter postoperative hospitalization time.It is well worth clinical promotion.

As the foundation of medical university students' comprehensive qualities, humanity qualities arc the basic and the most important qualities that a medical student should have. However, researches indicate that present medical students still have defects in humanity qualities. Therefore, to enhance the education of the humanities, it is necessary to take some measures such as to improve the courses, to infiltrate the spirits of humanity in major education and to launch practical activities to create an atmosphere of humanity so as to achieve this goal .

Objective In order to establish a rhesus monkey model of p53 gene silencing, firstly we screened and determined the effective silencing targets of p53 gene at the cellular level in rhesus monkey.Methods The expression of p53 gene was detected in COS-7 cells ( derived from the kidney of the African Green Monkey, Cercopithecus aethiops).Three small hairpin RNA ( shRNA) sequences targeting rhesus monkey p53 gene were designed, analysed by bioinformatics, and inserted into lentivirus-based gene silencing constructs FUGW-TDT.The plasmids of p53-RNAi and control vector were transfected into the COS-7 cells, respectively.The suppression of p53 mRNA was detected by real-time PCR, and the changes of p53 protein expression were detected by Western blot assay.Results p53 gene expression was detected in COS-7 cells.Bioinformatics analysis showed that three gene-silencing sequences were screened which lied in the open reading frame ( ORF) region and targeted 238 -258bp, 681 -701bp, 169 -189bp of the rhesus monkey p53 mRNA.At 48 hrs after transfection of the three silencing constructs, p53 mRNA was suppressed by(87.17 ±4.03)%, ( 72.62 ±4.11)% and(76.22 ±0.98 )%, and p53 protein was suppressed by ( 84.44 ±2.18 )%, ( 71.04 ±1.18)% and ( 74.17 ±0.95 )%, respectively. Conclusions We obtained three effective target sequences showing high efficiency in p53silencing, which can be used in further studies on gene silencing in rhesus monkey.

OBJECTIVE To study the effect of the ethanol extract of Fructus Psoraleae(EEFP)on endogenous metabolites in rat urine based on metabolomics. METHODS Male SD rats were orally administered with EEFP at the doses of 0.54,1.08 and 1.62 g · kg-1,respectively,once a day for two consecutive weeks. Urine samples were collected for 12 h after the last administration. Data were acquired with the MassLynx software based on ultra-performance liquid chromatography quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS). The principal component analysis(PCA)and partial least squares-discriminant analysis(PLS-DA)were used to analyze the difference of endogenous metabolites in different groups,then putative biomarkers were found through the orthogonal partial least-squares-discriminant analysis(OPLS-DA),variable importance in the projection(VIP)and t test and their relative intensity were determined. RESULTS The results of PCA showed that samples of each group were clustered,all the groups were separated,and that the distance between the EEFP groups and the blank control group was increased in a dose-dependent manner. The relative contents of p-cresol glucuronide and galactose-beta-1,4-xylose were 40.0 ± 11.2,2.7 ± 2.6,16.8 ± 6.3 and 45.9 ± 16.4,32.6±22.1,8.0±8.3 in the EEFP 0.54,1.08 and 1.62 g·kg-1 groups,respectively,significantly lower than those of the control group,which were 107.0 ± 26.9 and 82.3 ± 13.6(P<0.01),respectively. The relative contents of 5-L-glutamyl-taurine,and gluconolactone were 22.4 ± 10.0,47.6 ± 19.1 and 138.2 ± 18.8,337.3±64.0 in EEFP 1.08 and 1.62 g·kg-1groups,respectively,significantly higher than those of the blank control group,which were 2.6±1.6 and 20.5±6.8,respectively(P<0.01). The relative content of D-pantothenoyl-L-cysteine was 74.2 ± 31.5 in the EEFP 1.62 g · kg-1 group,significantly higher than that in the blank control group(0.6±0.5)(P<0.01). As the dose of EEFP increased,D-pantothenoyl-L-cysteine,5-L-glutamyl-taurine,and gluconolactone had an upward trend(P<0.01),while galactose-beta-1,4-xylose and p-cresol glucuronide had a downward trend(P<0.01). CONCLUSION The two-week administration of EEFP has effect on the endogenous metabolites in urine. The substances identified are mainly related to energy metabolism,taurine,tyrosine and glucose metabolism.

[ ABSTRACT] AIM: To investigate the SALL4 expression, proliferation and apoptosis in the LNCaP cells after transfection of SALL4 siRNA.METHODS: The expression of SALL4 at mRNA and protein levels was detected by real-time PCR and Western blotting.MTS assay, colony formation assay and flow cytometry were used to determine the prolifer-ation, colony formation ability and apoptosis of the LNCaP cells.The effect of SALL4 on the expression of Bax and Bcl-2 was analyzed by Western blotting.RESULTS:Compared with negative control group, the expression of SALL4 at mRNA and protein levels in LNCaP cells was down-regulated by transfection of SALL4 siRNA ( P<0.05 ) .The proliferation rate and colony formation ability were decreased, while apoptosis rate increased in si-SALL4 group (P<0.05).Higher expres-sion of Bax and lower expression of Bcl-2 in si-SALL4 group were observed ( P<0.05 ) .CONCLUSION:Down-regula-tion of SALL4 by siRNA not only suppresses LNCaP cell proliferation and colony formation, but also inhibits Bcl-2 expres-sion and activates Bax expression to induce apoptosis.
