Objective To investigate the discharge outcome and its clinical influential factors of acute poisoning in children, and to provide the clinical references for prevention. Methods Questionaire about acute poisoning in children made by the research group,the hospitalized children and the influential factors were analyzed according to the outcome. Results Among 168 cases of acute poisoning hospitalized children,the curative rate was 80.95%, 16 cases(9.52%) were improved,6 cases (3.57%)were quitted,1.20% was ' not curative' and 4. 76% died. The factors including age,treatment time, route of entry, varieties of poison, medical examination of admission were statistically associated with the discharge outcome.Conclusion The outcome can be improved through an intensive nurse of the children under the age of three and early treatment. The cases who were not poisoned by the invasion of gastrointestinal tract,paraquat poisoning,and those with abnormalities of breathing, pupilla, awareness in medical examination of admission would have poor discharge outcomes, and should be monitored closely and treated timely.

Objective:To investigate the influence of different salt concentration on the renal fibrosis and macrophages infiltration in salt sensitive hypertension.Methods:Dahl salt sensitive rats were randomly divided into the normal salt (0.3 ％ nacl) group,4 ％ high salt,8 ％ high salt groups at six weeks continuously feeding for 8 weeks,each group contained 15 rats.Tail-cuffmethod was used to value rat blood pressure at 8 weeks,Masson trichromatic method was used to detect renal fibrosis of the three groups at 8 week.Immunohistochemistry and Western blot method were used to depict the renal macrophage infiltration at 8 week.Results:1) The blood pressure of 4 ％ salt and 8％ high salt group rats were significantly higher than those of the normal salt group at 8week,meanwhile the blood pressure of 8 ％ high salt was further increased than that of 4 ％ high salt group at 8 week.2) The relative kidney weight and renal fibrosis of 4 ％ salt and 8 ％ high salt group rats were obviously higher than that of normal salt group at 8week,meanwhile the relative kidney weight and renal fibrosis of 8 ％ high salt were further increased than those of 4 ％ high salt group at 8 week.3) The macrophage infiltration of 4 ％ salt and 8％ high salt group rats were higher than that of the normal salt group at 8week,meanwhile the macrophage infiltration of 8 ％ high salt was further increased than that of 4 ％ high salt group at 8 week.Conclusion:Different high salt concentrations had different effect on the renal fibrosis and macrophage infiltration in the salt sensitive hypertension,high salt concentration could exacerbate the renal fibrosis and macrophage infiltration.

Objective: To understand the relationship between mental health status and vision-related quality of life( VRQL ) of students with moderate and high myopia, and to provide basis for the optimization of VRQL. Methods: Using convenient sampling method, the 8-18 years old students with moderate and high myopia were selected from Sichuan, Chongqing and Zhejiang. The mental health status and VRQL of students with moderate and high myopia were evaluated with Hospital Anxiety and Depression Scale and Quality of Life Scale for Ametropia. The multiple linear regression model was used to analyze the influencing factors for VRQL. Results: A total of 360 questionnaires were sent out and 354 were effectively recovered, with an effective rate of 98.33%. There were 116 ( 32.77% ) boys and 238 ( 67.23% ) girls; the median age was 16.65 years old. There were 211 ( 59.60% ) cases of moderate myopia and 143 (40.40%) cases of high myopia.There were 141 ( 39.83% ) found to be anxious and 176 ( 49.72% ) depressed. The median score of Quality of Life Scale for Ametropia was 64. The results of multiple linear regression analysis showed that sex ( β＇= -0.179 ), diopter ( β＇= 0.208 ), eyesight with glasses ( β＇= -0.229 ) and anxiety ( β＇= 0.439 ) were influencing factors for VRQL. Conclusion The mental health problems of the students with medium and high myopia are prominent; anxiety has a significant impact on the VRQL of the students.

Caveolae are specialized lipid rafts that form flask-shaped invaginations of the plasma membrane. Many researches show that caveolae are involved in cell signaling and transport. Caveolin-1 is the major coat protein essential for the formation of caveolae. Recently, several reports indicated that the other caveolae-associated proteins, Cavins, are required for caveola formation and organization. It's worth noting that Cavin-1 could cooperate with Caveolin-1 to accommodate the structural integrity and function of caveolae. Here, we reviewed that the relationship between Cavins and Caveolins and explore the role of them in regulating caveolae.

Objective To evaluate the effect of dietary ω-3 polyunsaturated fatty acid (PUFA) supplementation on lipopolysaccharide (LPS)-induced acute lung injury in rats.Methods Totally 58 male SD rats were divided into control group (n =10),model group (n =12),ω-3 PUFA high-dose group (n =12),ω-3PUFA medium-dose group (n =12),and ω-3 PUFA low-dose group (n =12).Seven days before model establishment,rats in the three ω-3 PUFA groups were orally given ω-3 PUFA at 1,0.5,and 0.25 g/kg body weight once per day,respectively,for seven consecutive days.Twenty-four hours after the last administration,all rats except those in the control group were given intravenous injection of LPS (6 mg/kg) at caudal vein to establish the model of acute lung injury.Body temperature was measured at 0,6,and 24 hour.Blood samples were collected from the eye venous plexus for routine blood tests and blood biochemical tests 24 hours after modeling.After the rats were sacrificed,the left lung was harvested for measuring the wet weight and dry weight and calculating the wet/dry weight ratio (W/D).The right lung was harvested for pathological observation under light microscope and calculation of semi-quantitative pathological index (PI).Results Twenty-four hours after modeling,deaths were noted in all groups except the control group.After injection of LPS,rats curled with little movements.At 6 hour,the body temperature was significantly higher in the model group than in the control group [(37.4 ±0.27)℃ vs.(35.9 ±0.05) ℃,P =0.00] ; it was (36.2 ±0.38)℃,(36.3 ±0.30)℃,and (36.3 ± 0.32) ℃ in the ω-3 PUFA high-,medium-,and low-dose groups,which were significantly lower than that in the model group (all P =0.01).The amounts of white blood cells,neutrophils,and lymphocytes increased in the model group,but showing no significant difference compared with the other groups.The serum glutamic oxalacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) levels were significantly higher in the model group than in the control group [(353 ± 235) U/L vs.(157 ± 55) U/L,P =0.02 ; (141± 103) U/L vs.(54 ±23) U/L,P =0.03] ; the ω-3 PUFA high-dose group had significantly lower GOT and GPT levels than the model group did [(167 ±94) U/L vs.(353 ±235) U/L,P =0.03 ; (63 ±57) U/L vs.(141 ± 103) U/L,P =0.04].The model group had significantly higher lung wet weight [(371 ±38) mg vs.(281 ±24) mg,P=0.01] and W/D value (7.34±1.40 vs.5.41 ±0.84,P=0.01) compared with the control group.Compared with the model group,the W/D value was significantly lower in the ω-3 PUFA high-,medium-,and low-dose groups (6.17 ±0.58,P =0.03; 6.17 ± 0.76,P =0.03; 6.13 ± 1.23,P =0.04).Light microscopy showed that the lung alveoli of the model group presented congestion,obvious expansion,and scattered inflammatory cell infiltration in interstitium,along with significantly increased PI compared with the control group (3.9±0.9 vs.0.0±0.0,P=0.00).The PI value was (2.1 ±0.3),(2.1 ±0.3),and (2.3 ± 0.5) in ω-3 PUFA high-,medium-,and low-dose groups,respectively,all significantly lower than that in the model group (all P =0.01).Conclusions The acute lung injury model could be successful established by intravenous injection of LPS.ω-3 PUFA at different doses can improve the acute lung injury of rats.It is therefore supposed that early enteral administration of ω-3 PUFA can alleviate LPS-induced acute lung injury,although the optimal dosage and timing need further research.
