Objective To compare the rat model of slow transit constipation (STC) established with gavage or feeding compound di-phenoxylate. Methods Forty Sprague-Dawley rats were randomly divided into gavage control group (A), gavage group (B), feeding control group (C) and feeding group (D) equally. Group B was given compound diphenoxylate suspension by gavage for 14 days while group A ac-cepted isodose normal saline. Group D were given feed containing compound diphenoxylate for 120 days while group C accepted normal feed. Carbon ink was poured into stomachs to observe the propelling rate after modeling, and the content of aquaporin 3 and aquaporin 4 were detected with immunohistochemistry. Results There were two rats died in group A and group B, respectively. The carbon ink propel-ling rate was lower in group D than in group B (P<0.05). Both aquaporin 3 and aquaporin 4 were more in group D than in group B (P<0.05). Conclusion STC rat model can be established by eating diphenoxylate feed for 120 days, which is safer and more stable than that of gavage for 14 days. Aquaporins in colons may play a role in onset and development of STC.

Spesis/severe sepsis remains a serious problem in pediatric intensive care unit.The mortality of sepsis/severe sepsis is still very high.The waterfall cascade reaction of cell factors is the main reason leading to the continued deterioration of the condition.Continuous blood purification technology can not only remove inflammatory mediators by adsorption and filtration function,but also improve the immune function,even reduce the mortality rate.But there is a controversial topic on the selection of the appropriate dose.This review not only introduces the effects of high-volume hemofiltration and low-volume hemofiltration from different aspects,but also analyses the influencing factors of different effects.

Objective To establish a multidrug-resistant cell subline NCI-H446/CDDP of human small cell lung cancer and characterize its biological properties. Methods The cell subline NCI-H446/CDDP was derived from human small cell lung cancer cell line NCI-H446 by exposing it to high concentration first followed by being cultured with gradually increasing dose of cisplatin, which used to be the first-line chemotherapeutic drug for lung cancer. The cell growth curve and the doubling time were determined by cell counting. The chemosensitivities of NCI-H446/CDDP and NCI-H446 to cisplatin, hydroxycamptothecine, vincristin, 5-fluorouracil and topotecan were tested and IC 50 measured by MTT. Changes in cellular morphology and ultrastructure were observed under inverted-microscope, scanning electron microscope and transmission electron microscope, respectively. Results Multidrug-resistant cell subline (NCI-H446/CDDP) of human small cell lung cancer was established successfully after culturing NCI-H446 in a high concentration of cisplatin first, followed by subjecting it to increasing concentrations of CDDP until they could stably grow in the culture medium containing 0.5?g/mL CDDP. The rate of cell proliferation of NCI-H446/CDDP was similar to that of NCI-H446, but the number of the former cells exhibiting S phase increased (20.24% vs 18.42% P

Objective:To investigate the resting energy expenditure of children with mechanical ventilation and analyze their association with anthropometric indicators (height, weight, and body mass index) and serum protein markers (pre-albumin, albumin, transferrin, and retinol).Methods:An observational study was held in Pediatric Intensive Care Unit(PICU) of Beijing Children′s Hospital, Capital Medical University, from August 2015 to April 2016.Critically ill children with mechanical ventilation were enrolled in this study.Inclusion criteria were as follows: (1)pediatric critical illness score<90 scores or meet the United States PICU admission criteria; (2)age>29 days, <18 years old; (3)mechanical ventilation>24 hours; (4) tidal volume >60 mL.Resting energy expenditure was determined by US Med Graphic Company CCM/D energy metabolism test system.German Famed Zywier intensive care bed with weight scale weighing, uniform measuring bed or meter measuring height, automatic biochemical analyzer and radioimmunoassay was adopted for the determination of albumin, pre-albumin, transferrin, retinol binding protein.SPSS 20.0 software was applied for carrying out Pearson line analysis correlation. Results:A total of 68 children were included in the study, including 36 males and 32 females, body weight (22.34±14.89) kg, height (122.23±14.89) cm, resting energy consumption (784.63±278.25) kcal(1 kcal=4.185 kJ), and resting energy consumption per kilogram of body weight (48.80±31.26) kcal.In anthropometric indicators, resting energy expenditure was significantly positively correlated with height, body weight ( r=0.764, 0.734, all P<0.05), a low positive correlation with body mass index( r=0.396, P<0.05). In serum proteomics, resting energy expenditure was negatively correlated with pre-albumin, transferrin ( r=-0.318, -0.282, all P<0.05), and a moderate negative correlation with retinol protein ( r=-0.505, P<0.05), while without correlation with albumin ( r=-0.075, P>0.05). Conclusions:The height, weight and serum proteomics of children with mechanical ventilation may affect resting energy expenditure.

Objective To explore the effect of participatory humanistic nursing on the quality of life and psychology of patients with gastric cancer. Methods From May 2015 to May 2016, 68 patients with gastric cancer were enrolled in the study. All patients were divided into the experimental group and the control group with 34 patients in each group according to the principle of double-blind randomization. Patients in the control group were given routine clinical nursing, and patients in the experimental group were given the participatory humanistic nursing care. The quality of life and psychological state were evaluated by European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and Symptom Checklist 90 edited by Derogatis and compared before nursing and after 6 months of nursing. Results There was no significant difference in the quality of life before nursing between two groups (P >0.05). After nursing, the scores of physical function, role function, emotional function, cognitive function, social function of the quality of life were 57.85±4.64, 68.43±5.23, 61.43±4.97, 58.47± 6.12, 53.57±5.54 in the experimental group and 43.56±4.56, 54.67±4.67, 56.34±4.74, 51.34±4.13, 50.46± 4.27 in the control group,and there were significant differences (t=2.593-12.808,P<0.01 or 0.05). There was no significant difference in the psychological state before nursing between two groups (P>0.05). After nursing, the scores of interpersonal sensitivity, depression, anxiety, hostility, terror, paranoia, psychosis of the psychological state were 1.65 ± 0.17, 1.40 ± 0.15, 1.45 ± 0.14, 1.46 ± 0.12, 1.52 ± 0.16, 1.54 ± 0.10, 1.43 ± 0.11 in the experimental group and 1.75±0.21, 1.72±0.24, 1.63±0.21, 1.75±0.23, 1.71±0.24, 1.65±0.10, 1.56 ± 0.12 in the control group, and there were significant differences (t=2.158-6.593, P<0.05 or 0.01).

Background:CDK14 is a novel cyclin-dependent kinase,which is overexpressed in a variety of cancer and related to their malignant behavior. Aims:To investigate the effect of CDK14 on proliferation of human esophageal carcinoma cells and its possible mechanism. Methods:Expressions of CDK14 and two cell proliferation markers,PCNA and Ki-67 were estimated in 8 fresh-frozen specimens of esophageal squamous cell carcinoma(ESCC),96 paraffin-embedded specimens of ESCC,and human ESCC cell line Eca-109 by Western blotting and immunohistochemistry. Correlations of CDK14 expression with the clinicopathological characteristics and prognosis of ESCC were analyzed. Serum starvation and release assay was performed to evaluate the relationship between CDK14 expression and cell cycle progression in Eca-109 cells. Furthermore,Eca-109 cells were transiently transfected with shRNA-CDK14 to reduce CDK14 protein level,and then the phosphorylation of tumor suppressor protein Rb,cell cycle progression and proliferation capability of Eca-109 cells were determined. Results:CDK14 was highly expressed in both ESCC tissue and cell line,which was paralleled with the expressions of PCNA and Ki-67 and correlated significantly with the tumor size,histological grade,invasiveness and metastasis of ESCC(P < 0. 05). The overall survival was poor in patients with high CDK14 expression than those with low CDK14 expression(P < 0. 05). Serum starvation and release assay showed that the expression of CDK14 was cell cycle-dependent. Knockdown of CDK14 reduced the expression level of phosphorylated Rb,induced significant G1 phase arrest and resulted in less colony formation in Eca-109 cells(P all < 0. 05). Conclusions:CDK14 is highly expressed in ESCC. It may promote cell cycle progression by phosphorylating downstream Rb protein,thus enhancing the proliferation of tumor cells,and ultimately participating in the occurrence and development of ESCC.

Objective To investigate the effects of laser irradiation on intracellular ROS(reactive oxidant species),intracellular calcium concentration(_i,and cell membrane integrity in the process of live cell imaging with confocal laser scanning microscopy. Methods The effects of a given laser irradiation on ROS,intracellular calcium concentration(_i and cell viability were revealed respectively by stained ECV-304 with H_2DCFDA,Fluo-4AM and calcein-AM/PI,and visualized and analyzed using ultra view LCI(live cell image)confocal microscopy. Results The irradiation of 488nm laser induced fluorescent intensity of DCF to increase abruptly and attain the climax in about 80 seconds,afterwards the fluorescent intensity fell and returned to the baseline.In the 70 minutes of the irradiation,the fluorescent intensity of intracellular Fluo-4 kept a slightly ascending tendency.The fluorescent intensity of calcein decreased 15minutes after the irradiation,and serval cells were PI positively stained.Conclusion 488nm laser irradiation induces intracellular reactive oxidant species(ROS) and calcium concentration to increase,but there is no significant influence on cell membrane integrity.
