Objective To study and explore the clinical effect of saline lavage on patients with acute oral poisoning. Methods From January 2014 to January 2017, 100 cases of patients with acute oral drug poisoning who admitted in the emergency department of our hospital were selected as the research object, the patients were randomly divided into the control group and the observation group by taking digital computer random grouping method, 50 cases in each group, the control group used clean water to lavage, the observation group used saline to gastric lavage, the success rate of rescue, serum sodium concentration, mean arterial pressure and complication rate were compared between two groups. Results The success rate of rescur in the observation group was significantly higher than the control group (P<0.05); after gastric lavage, serum sodium concentration and mean arterial pressure in the observation group had not appear obvious fluctuation, and serum sodium concentration and mean arterial blood pressure in the control group were lower than those before gastric lavage (P<0.05); the incidence of complications in the observation group was significantly lower than that the control group (P<0.05). Conclusion The use of physiological saline for acute oral poisoning patients with gastric lavage, can effectively improve the success rate of rescue, reduce complications, but also to avoid water and electrolyte disorders.

BACKGROUND:Animal models of atherosclerosis play an important role in the research of the pathogenesis, occurrence and development of atherosclerosis, as wel as in the prevention and treatment of atherosclerosis. OBJECTIVE:To summarize and discuss the establishment of atherosclerosis models, explore the current situation and advance of atherosclerosis models, compare the advantages and disadvantages of various methods, and provide evidence for clinical investigation. METHODS:A computer-based online search was conducted in SinoMed, VIP, Wanfang and PubMed databases by using the key words of “animal model, atherosclerosis, progression” from January 1990 to December 2014. The language was limited to both Chinese and English. Relevant articles were screened according to inclusion and exclusion criteria. The documents about the methods of atherosclerosis model preparation, method improvement as wel as their advantage and disadvantage were summarized. RESULTS AND CONCLUSION: A total of 137 articles were included. Among them, 93 articles published earlier, duplicated, and similarly were excluded, and 44 references were finaly included. The results demonstrated that, the main characteristics of models established with the high-fit diet are lipid storage. This method is commonly used due to its fixable operation. However, this method needs a long time and the position of athermanous plaque is unstable. That’s the reason why immune method, nerve and mechanical damaged method, hemodynamic method and genetic engineering method emerge. These novel methods facilitate the model establishment, and have their advantages and disadvantages. To a certain extent, they are different from human spontaneous type. Partial ligation plays irreplaceable functions when studying complications of atherosclerosis. The athermanous plaque formed by baloon injury shows accurate position, which is convenient for researchers to observe the changes of athermanous plaque after conducting al kinds of interventions. This model based on immunological method could provide guidance of vaccine research for atherosclerosis prevention. Therefore, they can choose more appropriate model formation method according to their own needs.

Objective To investigate whether human breast milk may bind to hepatitis B surface antigen (HBsAg) and its characteristics.Methods Breast milk samples from five women with negative HBsAg and hepatitis B surface antibody (anti-HBs) at one to two months post delivery were fractioned into cream and skimmed milk by centrifugation.The human breast milk and each fraction as well as cow and goat milk samples,served as controls,were separately incubated with highly purified yeast recombinant HBsAg,followed by determination of their binding capability to HBsAg by enzyme linked immunosorbent assay (ELISA) and the inhibition rate for binding of HBsAg to anti-HBs by quantitative chemiluminescence microparticle immunoassay.After boiled for 1 min or pasteurized in 65 ℃ for 30 min,the thermal stability of the active components of milk was detected.One-way ANOVA and SNK tests were performed for statistical analysis.Results The operative concentration of HBsAg was 0.1 μg/ml.Breast milk from all five women showed significantly better binding capability to HBsAg than cow or goat milk (1.306±0.300 vs 2.157±0.150 and 2.232±0.093,F=34.303,P＜0.01).The quantitative experiments showed that the inhibition rate of human breast milk was higher than that of the control group [(74.26± 17.26)％ vs (0.00±5.50)％,F=57.806,P＜0.01].The binding ability to HBsAg of skimmed milk was comparable with that of whole milk,indicating milk protein(s) played critical roles in binding to HBsAg (0.877 ± 0.486 vs 0.513 ± 0.069 and 0.376 ± 0.146,F=44.475,P＜0.01).After boiled for 1 min or Pasteurization,the binding ability to HBsAg of whole breast milk remained,but that of skimmed milk went down (F=16.598,P＜0.01).Both whole breast milk and skimmed milk could inhibit the binding of HBsAg to anti-HBs (F=278.341 and 269.408,both P＜0.01).Conclusions The inhibition of binding to HBsAg by human breast milk indicates that human milk may interact with HBsAg.The active components mainly exist in milk proteins and are thermal stable.

Objective To understand the schedule and effectiveness of water-improving defluoridation projects comprehensively in control of fluorosis in drinking-water-borne endemic fluorosis areas in Shaanxi Province,and to provide a scientific basis for making strategies in prevention and control the disease for the next step.Methods The progress of drinking-water-borne endemic fluorosis water-improving defluoridation projects and operation condition were investigated in Shaanxi (fluoride content of drinking water was greater than 1.2 mg/L in the endemic areas) in 2014,and children aged 8 to 12 in 32 epidemic villages of six counties including Jingbian,Dingbian,Dali,Jingyang,Qian and Liquan were selected to survey dental fluorosis.Results In Shaanxi Province,the number of villages with water fluorine content of more than 1.2 mg/L was 5 005 and water improvement rate was 83.42％ (4 175/5 005),water-improving projects operated normally rate was 85.05％ (3 551/4 175),and scraped was 37,accounted for 0.89％ (37/4 175).There were 830 epidemic villages without water-improving projects in Shaanxi Province,and high fluoride exposed population was 579 400,mainly distributed in Yulin,Xianyang,Weinan and Yan'an cities.A total of 1 849 children aged 8 to 12 in the 6 counties were examined,the detection rate of dental fluorosis was 56.57％ (1 046/1 849),the index of dental fluorosis was 1.11.Conclusion In drinking-water-borne fluorosis epidemic areas of Shaanxi,the improved-water rate is generally high,and the normal operation of waterimproving projects is overall good,but the measures for water-improving defluoridation must be reinforced and improved.
