Objective To investigate the role of AQP2 and Na +-K +-ATPase in the pathogenesis of kidney injury with multiple organ dysfunction syndrome,and try to find the express characteristics of them.Methods A total of 72 healthy rats were randomly (random number) divided into two groups:control group (n =24) and Lipopolysaccharide group (n =48).The Lipopolysaccharide group rats were injected with 5 mg/kg lipopolysaccharide at the beginning while the control group was 0.9％ sodium chloride.After the model was succeeded,the rats were put to death at 6 h,12 h,24 h,2 days,3 days and 5 days equally.The urine and blood were collected.Blood were used biochemical tests to check.kidney AQP2 protein and mRNA expression level in the organization were applied the immune organized and RT-PCR technique to detect.Applied kit for determining the content and activity of sodium/potassium-atpase.Results The volume of urine in LPS group decrease quickly at 12 h and 24 h,but increased after 2 days.Urea nitrogen and creatinine increased gradually,and peaked at 48 h,after then gradually decline.AQP2 mRNA and protein expression decreased,and minimize at 48 h.The content of Na+-K+-ATP ase has no obvious difference,but the activity significantly decreased at the beginning,then increased gradually,but it was still lower than the control group.Conclusions In renal injury rats model with multiple organ dysfunction syndrome,AQP2 is the structure of renal reabsorption function,while Na +-K +-ATPase directly involved in or indirectly reflected the state of kidney energy metabolism.Recovery of AQP2 protein and energy metabolism,before the rat kidney function improved.

0.05). Tanreqing intervention treatment had better influence on the pneumodynamics and arterial blood gas than the therapentic influence on that in the control group, the functional improvement rate of lung and extra-pulmonary organs of study group obviously outstripped the rate of control group, and the incidence of VILI and VAP was also obviously decreased in the former group. The mortality in ICU for multiple organ failure (MOF) of Tanreqing intervention group was 16%, which was obviously lower than that (48%) of the control group (P

OBJECTIVETo analyze the status of acute upper respiratory infection and influenza-like illness (ILI) among community residents in Jinan in 2015, and to make a understand of the patient's medical treatment behavior and influenza vaccination coverage status in 2014.

METHODSBalloting method and convenient sampling method were used to launch a household survey. The residents who had been in Jinan for more than 3 months were selected, to investigate the residents' attack ratio of acute upper respiratory and influenza-like from Jan. 8 to Feb. 7, 2015. Totally, 1 300 persons from 410 families were involved in this survey which recovered 1 241 valid questionnaires with the efficiency of 95.5%. Based on the national age-urban demographic statistics in 2010, the attack rates of acute respiratory infections, influenza-like illness were estimated by the direct standardization method, and the influenza vaccination rates were also calculated in this study. χ(2)-test method was used to compare the different status of incidence and vaccination among residents with different features.

RESULTSThe attack rate of acute upper respiratory infection and influenza-like illness in Jinan from January 8, 2015 to February 7, 2015 were 30.2% (375 cases), and 6.1% (76 cases), respectively, with a standardized rate of 29.1% and 5.4%. 5.3% (66 cases) of the residents have vaccinated with the influenza vaccine inoculation, with an adjusted rate of 3.8%. The attack rate difference of acute upper respiratory tract infections was statistically significant between each age group (χ(2)=17.121, P= 0.002). The 0-4 age group had a highest attack rate (45.4%) of acute respiratory infection, while the 15-24 age group got the lowest (26.5%). 38.9% (146 cases) of patients went for a treatment in hospital. Among them, 37.7% (55 cases) of them selected the county level hospitals for treatment, 37.7% (55 cases) selected the community level hospitals, and 24.6% (36 cases) selected the individual clinic. Significant differences of influenza-like illness attack rate between each age group were also found in this study (χ(2)=76.79, P<0.001). 0-4 age group had the highest attack rate (22.7%). 81.6% (62 cases) of the ILI sought treatment in the hospital, of which 53.2% (33 cases) selected county level hospital or above, and 33.9% (21 cases) selected community hospital, and 12.9% (8 cases) selected the individual clinic.

CONCLUSIONThe attack rate of acute upper respiratory infections among the residents of Jinan was high, whereas that of influenza-like illness was relatively low. 0-4 age group had a higher risk of ILI than other age groups. Most of the cases were likely to take the treatment in large hospitals. In general, the coverage rate of influenza vaccination was relatively low.
