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.

Cyclic amp receptor protein (CRP) is a global transcriptional factor in many prokaryotes, capable of governing nearly half of the total genes in Escherichia coli. Through the method of error-prone PCR or DNA shuffling, we can first obtain CRP mutant library and then get the expected cell phenotype with enhanced resistance. In this article, we reviewed the following desired phenotype: enhanced tolerance towards oxidative stress, improved osmotolerance, enhanced organic solvent (toluene) tolerance, improved acetate tolerance of E. coli fermentation and improved ethanol tolerance during bio-ethanol production. We then concluded that CRP can also be applied in other host cells to get desired phenotypes. Last, we predicted potential applications of mutant CRP transcriptional factor.

Objective To investigate status about the heart rate variability and executive function in patients with insomnia.Methods The study involves 165 cases of patients with insomnia and 92 cases normal.The Pittsburgh Sleep Quality Index (PSQI) screening for insomnia,Wisconsin Card Sorting Test (WCST) for the assessment of executive function and Self-generate Physiological Coherence System (SPCS) were used to collect the data of heart rate variability (HRV).Results The SDNN,RMSSD,TP,LF,HF of HRV of the insomnia group were significantly higher than these factors of control group (t=2.712,2.726,2.427,2.542,2.338,P＜0.05 or P＜ 0.01).In the WCST,number of completed categories,conceptualization percentage of the group of patients with insomnia were significantly lower than the control group (t=-2.368,-2.165,all P＜0.05),persistent errors,persistent error percentages,continuous number of responses of patients' group were significantly higher than the control group (t=2.712,2.991,2.690,all P＜0.01).TP,LF,HF,LF/HF of HRV and the number of error responses,persistent errors,persistent error percentages,continuous number of responses of WCST had significant negative correlations (r=-0.171--0.245,P＜0.05 or P＜0.01),while the conceptualization percentage were significantly positively correlated (r=0.198-0.227,P＜0.05 or P＜0.01).Conclusion The results show that insomnia not only cause individual autonomic disorders,but damage the executive function of prefrontal.HRV and executive function in patients with insomnia have close relationships.

Objective To explore the feasibility of detecting the cytokeratin 20 (CK-20) mRNA in exfoliated urothelial cells for the diagnosis of bladder carcinoma. Methods Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the expression of CK-20 mRNA in cells collected from the urine of 45 cases of bladder cancer, 15 cases of cystitis accompanied by hematuria, 10 healthy volunteers, and 7 different cell lines, including bladder cancer cell line T24, kidney cancer 786-0 and GRC-1, breast cancer MCF-7 and MDA-MB-435, and ovary cancer SKOV 3 and 3AO. Results CK-20 mRNA expression was detected in 36 of 41 cases of bladder transitional cell carcinoma (87.80%), in 18 of the 21 GⅠ patients (85.71%), in 11 of the 13 GⅡ patients (84.62%), in 7 of the 7 GⅢ patients (100%), in 20 of the 22 T a-1 patients (90.91%), and in 16 of the 19T 2-4 patients (84.21%). Sensitivity of the method was found to be 87.80%, whereas specificity was 73.33%. In 15 patients with hematuria, there were 4 cases of false positive: 1 case of BPH, 1 case of atypical hyperplasia, 1 case of chronic inflammation, and 1 case undergoing TURP previously. CK-20 amplification band was also obtained in all of 19 cases of bladder transitional cell tumor tissues and bladder cancer cell line T24, but not in 4 patients with non-transitional cell carcinoma and 6 other tumor cell lines. No false positive cases were found in the healthy control group. Conclusion These results suggest that CK-20 might be a useful tumor marker for early noninvasive diagnosis and follow-up of bladder cancer by detecting CK-20 mRNA expression of uroepithelial cells from the voided urine specimen by RT-PCR.

[ ABSTRACT] AIM:To explore the role of SHARPIN in regulation of Rip1 in castration-resistant prostate cancer LNCaP-AI cells.METHODS:The LNCaP-AI cells were treated with TNF-α+Z-VAD ( an inhibitor of pan-caspase) to activate necroptosis, which were compared to the cells treated with TNF-α+Z-VAD+Nec-1 ( an inhibitor of Rip1 ) .A blank group and a TNF-α-treated group were set up as controls.The cell viability in each group was measured by MTS as-say.In addition, SHARPIN was knocked down by siRNA, and the inhibitory efficiency was evaluated by RT-qPCR.The expression of Rip1 at mRNA and protein levels after knocking down SHARPIN was determined by RT-qPCR and Western blot to explore the underlying mechanism of regulatory network of necroptosis in prostate cancer.RESULTS: Compared with blank control group and TNF-α-treated group, the viability of LNCaP-AI cells treated with TNF-α+Z-VAD decreased by 28%(P<0.05).After treated with TNF-α+Z-VAD+Nec-1, the LNCaP-AI cells showed no significant difference in the viability compared with blank control and TNF-α-treated groups.Taken together, necroptosis may be an important way of cell death in LNCaP-AI cells.Besides, the expression of Rip1 at protein level was up-regulated following the inhibition of SHARPIN using siRNA, indicating that down-regulation of SHARPIN enhanced necroptosis via activating Rip1 in
LNCaP-AI cells.CONCLUSION:Necroptosis is an important way of cell death .Inhibition of oncogenic factor SHARPIN enhances necroptosis via activating Rip1 in LNCaP-AI cells.
