Objective To study the changes of adriamycin-induced glomerular epithelial cells (GECs) permeability and cytoskeleton, and to explore the role and possible mechanism of epithelia growth factor (EGF) on adriamycin-induced glomerular epithelial barrier function. Methods Rat GECs on Milicell-PCF Inserts were exposed to adriamycin (0.5 ?mmol/L) 24 hours in the absence or presence of EGF. The paracelluar permeability to BSA and cell viability were evaluated. The expression of F-actin and alpha-actinin were analyzed by immunofluorescence and Leica laser scan confocal microscopy. Results After induced by adriamycin for 24 hours, paracelluar permeability to BSA and F-actin reorganization rate increased. Disassembling of cortical cytoskeleton architecture was observed. Stress fiber in cytoplasm disappeared. Alpha-actinin staining showed perinuclear enhancement, which is different from normal cytosolic pattern. EGF significantly reduced adriamycin induced effect. Higher level of BSA passed through GEC monolayer in a dose-dependent manner. EGF prevented adriamycin-induced cytoskeletal reorganization. Disassembled cortical cytoskeleton was recovered, and stress fiber appeared again. Alpha-actinin staining mainly exhibited cytosolic uniform distribution as control GEC. In addition, administration of either AG1478, a specific inhibitor of EGF-receptor tyrosine kinase, or U73122, a specific inhibitor of PLC? before EGF treatment attenuated the EGF-mediated effect, whereas neither AG1478 nor U73122 exerted influence in the absence of EGF. Conclusions Adriamycin increases GEC paracellular permeability to BSA as a result of adriamycin-induced cytoskeleton disassembling and disruption. EGF may prevent adriamycininduced cytoskeleton reorganization and maintain glomerular epithelial barrier function through EGF mediated EGF-EGFR-PLC? signal pathway.

Nosocomial infection is a major challenge in modern hospital management. It affects not only patient safety but also the health of the health care workers. Inappropriate control of nosocomial infections will lead to serious results. China introduced the concept of nosocomial infection control in mid 1980s. Since then, tremendous achievements have been made, while lags still exist when compared with the developed countries. Further efforts should be made to strengthen discipline construction and develop scientific control approaches.

Objective To summarize the experience of nursing cancer patients with Wernicke encephalopathy (WE) after gastrointestinal surgery. Method The clinical data of 6 patients with WE after gastrointestinal surgery in our hospital from January 2005 to June 2015 were retrospectively analyzed to summarize the nursing strategies. Results All the 6 patients showed mental changes of different types, 5 patients developed with ocular manifestations and one patient with ataxia. Only one patient showed the classic triad of the disease at clinical presentation. All the 6 patients had characteristic manifestations on cranial MRI and received thiamine (vitamin B1) at diagnosis. Four patients were completely recovered and 2 were partially recovered. Conclusion Timely sufficient thiamine supplementation during the perioperative period is the key to prevent and treat WE in the patients with gastrointestinal cancer. Careful observation of the patients′ mental state and the effective nursing for the special classic triad of the disease are critical for a better prognosis.

Objective To observe the expression and distribution of angiopoietin-like protein 3(ANGPTL3) in kidney of adriamycin(ADR)-induced nephrotic rats, and to explore the possible association of ANGPTL3 with the development of proteinuria and hyperlipidemia. Methods Adriamycininduced nephrotic rat models were established by a single injection of adriamycin via the tail vein. Immunohistochemical staining (IHS)and dot-ELISA were used to examine the expression and distribution of ANGPTL3 in kidney and the level of ANGPTL3 in serum of ADR rats at day 7,14, 21 and 28 after adriamycin injection. Results (1) In ADR rats, urinary protein and the level of triglyceride and cholesterol in serum increased significantly at day 14 (P

Objective To study the expression of angiopoietin-like protein 3(ANGPTL3) mRNA successively in kidney of adriamycin (ADR)-induced nephrotic rats during the development of proteinuria, and to disclose the possible assosiation of ANGPTL3 with proteinuria. Methods Adriamycininduced nephrotic rat models were established by a single injection of adriamycin via the tail vein. Glomeruli and cortex tubuli of rats were dissected by laser microdissection. Real time quantitative RT-PCR was used to study the expression of ANGPTL3mRNA in kidney of ADR rate at 7, 14, 21 and 28 days successively following adriamycin injection. Results (1) In ADR rats, urinary protein and the level of triglyceride and cholesterol in serum increased significantly at day 14 (P

AIM: To examine the inhibition of matrix metalloproteinase (MMP) activity by doxycycline (Doxy) and its effect on vascular smooth muscle cells (SMCs) proliferation, neointimal hyperplasia and vascular remodeling. METHODS: The model of rat common carotid artery injury was established by balloon-dilatation. Doxy was administered to the animals of treatment group at dose of 30 mg?kg -1?d -1. The activity of MMPs in the tissue of injured carotid arteries was measured by gelatin zymography. The thickness and area of neointimal, lumen area and the proliferation of SMCs were measured by histological and morphometric analysis. RESULTS: 1. After Doxy treatment, the activity of MMP-9 in the carotid arteries was reduced by 26.3% and 34.5% compared to that in rats without Doxy treatment at 24 hours and 3 days after balloon injury, respectively (P

To establish a method for determination contents of schizandrin, tanshinone I, cryptotanshinone, tanshinone II (A) and schizandrin B in rongxin pills. The HPLC method was performed on an Agilent C18. The mobile phase was composed of methnol and water wish gradient elution. The flow rate was 1.0 mL x min(-1). The column temperature was 30 degrees C and the detection wavelength wash 240 nm.

BACKGROUND:Due to the differences of sport events and individual metabolic characteristics of athletes, it is difficult to establish uniform biological indexes for training monitoring. Current individual evaluation is a longitudinal analysis relying on experience or numerical variation width, which is less objective.OBJECTIVE: To explore the individual function assessment and monitoring by monitoring blood biochemical indexes and brain function indexes in elite gymnasts, in order to accurately reflect the body changes resulting from training loads. METHODS:Thirty gymnasts from the Chinese national gymnastics team preparing for London Olympic Games were enroled in this study and monitored from the last winter training until the London Olympic Games. The blood biochemical indicators and brain function indicators were measured and assessed individually according to according to the principle of quality control (alert value=mean±SD, and controled variable=mean±2SD). RESULTS AND CONCLUSION:Under the relatively uniform test conditions, it is feasible to individualy assess the blood biochemical and brain function indexes of elite gymnasts in accordance with the principle of quality control, which is more accurate and objective to reflect the body changes under training load and the current state of athletes. In addition, the combined monitoring of blood biochemical indexes and brain function indexes is more comprehensive to evaluate the body function and status of elite gymnasts.
