Conclusion Endoscopic ultrasonography is effective in diagnosing and preoperative staging of rectum carcinoma.

Objective:To investigate the expression of Plk1 ( Polo-like kinase 1 ) and Chk1/2 ( Checkpoint kinase 1/2 ) in primary hepatic carcinoma tissue and HepG2 cell. Methods: Using immunohistochemistry chemical method detected expression of Plk1,Chk1/2 protein in 40 cases of primary hepatic carcinoma tissue and 16 cases of non-tumor tissue of liver. Western blot was applied to detect the expression of Plk1 and Chk1/2 protein in HepG2 cells, and gray value was measured by using the quantitative analysis. Results:The positive rate of Plk1,Chk1/2 protein expression in primary hepatic carcinoma was 57. 5%,75. 0% and 22. 5%respectively,compared with positive rate in the liver of non-tumor tissue were 0%,25. 0% and 56. 3%. The expression of Plk1 and Chk1 protein in primary hepatic carcinoma tissue is higher than that in non-tumor tissue of liver,and the difference was statistically sig-nificant( P<0. 05 ) . The expression of Chk2 in primary hepatic carcinoma was lower than that in hepatic non-tumor tissue, and the difference was statistically significant(P<0. 05) too. The expression of Plk1,Chk1/2 protein were detected in HepG2 cells and the relative expression rate of Plk1,Chk1/2 protein were 0.39±0.0226,0.08±0.0249 and 0.01±0.0066 respectively,the difference between them was statistically significant. The expression degree was Plk1>Chk1>Chk2. Conclusion: Plk1,Chk1 protein in primary hepatic carcinoma was up-regulated,while Chk2 protein was down-regulated in these tissues. The expression degree was Plk1> Chk1>Chk2. There were relatively selective expression in primary hepatic carcinoma tissue of Plk1,Chk1 protein,then Plk1 and Chk1 might be ideal targets for therapy of primary hepatic carcinoma.

Objective To explore the influence of early rapidly increased amino acid dosaging on the nitrogen balance and growth in preterm infants.Methods A total of 37 prematures admitted to our NICU within 24 hours after birth and with birth weight of 1 000 g to 1 800 g from November 2011 to January 2013 were randomly divided into study group (n =18) and control group (n =19).Parenteral nutrition (PE) was provided in both groups within 24 hours after birth.The starting amino acid dose was 1.5g/kg per day,then rose by 1 g/kg per day in study group and by 0.5 g/kg per day in control group,until to maximum of 3.5 g/kg per day.The dosage of lipids,glucose,and electrolytes in parenteral nutrition was provided routinely.The trial was double-blinded.Results In the first 5 days of PE,the nitrogen balance had no significant difference between these two groups (F =0.025,P =0.652) ; however,the time of regaining birth weight was significantly shorter in study group [(7.23±2.48) d] than in control group [(9.42±2.03) d] (t=-2.090,P=0.044).There were no differences between these two groups in trems of completely feeding time,weight gain rate,head circumference growth rate,length of hospital stay,and hospital costs (all P ＞ 0.05).Meanwhile,the rates of neonatal necrotizing enterocolitis,sepsis,mechanical ventilation administration,and damage of hepatic and renal function were also not significantly different.The administration of different dosages of amino acids did not affect the energy intake in both groups (F =1.893,P =0.218).Conclusions Prematures need early amino acid administration,with a starting dosage of more than 1.5 g/(kg · d).Rapid increase of amino acid dosing will not affect early nitrogen balance in premature infants; meanwhile,it contributes to weight gain without increasing the complications and hospitalization costs.

To construct, express, purify and identify the Myc-R9-EGFP fusion protein and validate its transduction activity in the cultured porcine embryo fibroblasts. cDNA of pig c-Myc gene was amplified by RT-PCR with specific primers of 9 arginine (R9) from the primordial genital ridges and inserted into prokaryotic expression vector pET-28a-EGFP. After DNA sequencing confirmation, the recombinant plasmid was then transformed into BL21 (Escherichia coli) strain. After IPTG induction, the target fusion protein was efficiently induced to express, successfully purified by Novagen His-Bind kit, identified by SDS-PAGE and Western blotting. Finally, its high transduction activity in the porcine embryo fibroblasts was validated. The purified Myc-R9-EGFP fusion protein and the validation of its transduction activity in fibroblasts have provided an experimental foundation for further studies on the biological characterization of Myc protein, and soundly facilitated the further study of establishing pig induced pluripotent stem cells by recombinant protein.

China still has more than 30,000 patients of advanced schistosomiasis while new cases being reported consistently. D-dimer is a fibrin degradation product. As ascites being the dominating symptom in advanced schistosomiasis, the present study aimed to explore a prediction model of ascites with D-dimer and other clinical easy-achievable indicators. A case-control study nested in a prospective cohort was conducted in schistosomiasis-endemic area of southern China. A total of 291 patients of advanced schistosomiasis were first investigated in 2013 and further followed in 2014. Information on clinical history, physical examination, and abdominal ultrasonography, including the symptom of ascites was repeatedly collected. Result showed 44 patients having ascites. Most of the patients' ascites were confined in the kidney area with median area of 20 mm². The level of plasma D-dimer and pertinent liver function indicators were measured at the initial investigation in 2013. Compared with those without ascites, cases with ascites had significantly higher levels of D-dimer (0.71±2.44 μg/L vs 0.48±2.12 μg/L, P=0.005), as well ALB (44.5 vs 46.2, g/L) and Type IV collagen (50.04 vs 44.50 μg/L). Receiver operating characteristic curve analyses indicated a moderate predictive value of D-dimer by its own area under curve (AUC) of 0.64 (95% CI: 0.54–0.73) and the cutoff value as 0.81 μg/L. Dichotomized by the cutoff level, D-dimer along with other categorical variables generated a prediction model with AUC of 0.76 (95% CI: 0.68–0.89). Risks of patients with specific characteristics in the prediction model were summarized. Our study suggests that the plasma D-dimer level is a reliable predictor for incident ascites in advanced schistosomiasis japonica patients.
