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.

Objective In this study,we measured the levels of urinary monocyte chemoattractant (MCP)-1 and interferon-γ-inducible protein (IP-10) and further analyzed their associations with clinical and pathological data in lupus nephritis patients in order to find the non-invasive biomarkers which canpredict disease activity.Methods MCP-1,IP-10,VEGF levels were measured in urine samples from 64 lupus nephritis patients and 20 healthy volunteers.Clinical disease activity was determined by SLEDAI and BILAG scores.The lupus nephritis patients were divided into two groups:active disease group (SLEDAI scores ≥ 10points,n=36) and non-active group (SLEDAI score＜10 points,n=28).Of all patients enrolled,37 patients had a concomitant kidney biopsy performed at the time of urine collection.The predictive performance of uri-nary MCP-1 and IP-10 for renal flare,the Student's t test,Mann-Whitney U test,Chi-square test,and re-ceiver operating characteristic (ROC) curves were constructed for analysis.Results The urinary MCP-1 and urinary IP-10 levels of the active group was significantly higher than that of the non-active group [MCP-1672.39(318.05,2 554.23)pg/ml vs 152.52,(55.61,330.44)pg/ml,Z=-4.717,P＜0.01; IP-10 (38±19) pg/ml vs (22±16) pg/ml,t=3.576 P＜0.01].The level of urinary MCP-1 was positively correlated with the levels of hematuria and 24 hours protein quan-tification,as well as the scores of SLEDAI and BILAG (rbemahuria=0.570,P=0.000; r24hpro=0.569,P=0.000; rSLEDAI=0.600,P=0.000; rBILAG=0.606,P=0.000),and it was also positively correlated with the scores of cellular crescent,wire loop,and AI (rCC=0.405,P=0.015; rwire loop=0.430,P=0.014; rAI=0.352,P=0.003),while nega-tively correlated with the level of C3 and plasma albumin (rc3=-0.564,P=0.000; ralb=-0.587,P=0.000).It had no correlation with the scores of wire loop and CI (P＞ 0.05).The level of uIP-10 was positively correlated with the protein quantification in 24 hours and the scores of SLEDAI and BILAG (r24hpro=0.305,P=0.018; rSLEDAI=0.334,P=0.009; rSILAG=0.496,P=0.000),while negatively correlated with the level of C4 (rC4=-0.301,P=0.016).The R0C curve of uMCP-1 to predict the activity of SLE showed that its specificity was 75.0％,sensitivity was 83.3％,and the area under the ROC curve was 0.85±0.05.The ROC curve of urinary IP-10 to predict the activity of SLE showed that its specificity was 50.0％,sensitivity was 97.2％,its area under the ROC curve was 0.74±0.06.The ROC curve of urinary MCP-1 to predict renal flare shows that its specificity was 45.5％,its sensitivity was 100％,and the area under the ROC curve was 0.74±0.80.The ROC curve of urinary IP-10 to predict renal flare showed that its specificitywas 36.4％,its sensitivity was 73.3％,and its area under the ROC curve was 0.49 ±0.10.Conclusion Urinary MCP-1 and urinary IP-10 predict renal flare in patients with lupus nephritis.Furthermore,urinary MCP-1 is a more specific and sensitive forecaster of renal flare in patients with a history of lupus nephritis than urinary IP-10.

Objectives To observe the pre and post-operational changes of the expressions of survivin, caspase-3 and CD44V6 in patients with colorectal cancer after intra-abdominal implantation of sustained releasing fluorouracil. Meth-ods Sixty-four patients with colorectal cancer (Dukes’stage of B and C) were divided into treatment group and control group, 32 patients in each group. The standard radical surgery was performed in two groups of patients. The fluorouracil im-plants were implanted intra-abdominally in treatment group. The peripheral blood levels of surviving and caspase-3 were de-tected by RT-PCR. The level of CD44V6 was detected by flow cytometry in two groups of patients. Results There were no significant differences in levels of survivin, caspase-3 and CD44V6 before surgery between two groups (P>0.05). The level of survivin (0.362 ± 0.183) was significantly lower at 14 days after operation in treatment group than that of control group (0.585±0.207), but the level of caspase-3 (2.001±0.146) was significantly higher than that of control group (1.654±0.111). The levels of CD44V6 were significantly lower in treatment group (1.857±0.535) and control group (3.471±0.496) after opera-tion than those before operation (9.557±1.170 and 9.729±0.943, P＜0.05), and the level of CD44V6 was significantly lower in treatment group than that of control group (P＜0.05). Conclusion The implant for the sustained release of fluorouracil showed a positive impact on micrometastases and prognosis of colorectal cancer, while improved the long-term efficacy of postoperative colorectal cancer.

Objective To compare the clinical effect and safety evaluation of three different dose regimens for treating children with viral encephalitis.Methods Totally 126 cases treated in Xi'an Central Hospital from January 2010 to December 2015 were randomly divided into observation group 1 (ganciclovir combined with gangliosides,42 cases),observation group 2 (ganciclovir combined with gamma globulin,43 cases),and control group (39 cases).The clinical effect and levels of NSE,inflammatory cytokine were compared in the three groups.Results The total effective rate in observation group 1 was 95.24％ and that of observation group 2 was 93.02％,which were significantly higher than that of control group (79.48％).The disappearance time of headache,fever,convulsions,clouding of consciousness,meningeal irritation sign,cerebrospinal fluid abnormalities,and length of stay in observation groups (both 1 and 2)were significantly shorter than those in control group (P ＜ 0.05);After therapy,the levels of NSE in three groups were obviously decreased compared with those before therapy (P ＜ 0.05),and those in observation group were significantly lower than the control group (P ＜ 0.05);the levels of inflammatory cytokine in all three groups were obviously decreased compared with those before therapy (P ＜ 0.05),and that of observation group 1 had no statistical difference with the normal group,whereas that in control group was significantly higher than the normal group (P ＜ 0.05).Conclusion Ganciclovir combined with gangliosides as well as ganciclovir combined with gamma globulin were both effective methods in treating children with viral encephalitis and could decrease levels of inflammatory cytokine.Ganciclovir combined with gangliosides could effectively repair nerve damage,which deserves clinical expansion.

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 the in vitro effects of platelet-rich plasma(PRP) on human periodontal ligament fibroblasts(PDLFs). Methods: Various concentrations of PRP (10, 50, 100, 200, 300, 500 ml/L) were applied to primary cultures of human PDLFs. MTT assays were utilized to assess cell proliferation ability. Migration was determined by assessing the cell response to a concentration gradient with Transwell chamber. Differentiation was assessed using alkaline phosphatase (ALP) kit. Results: A beneficial effect on proliferation was observed, especially in response to 200 ml/L PRP.PRP had stimulatory effects on the migration of human PDLFs. PRP facilitated differentiation of PDLFs. Conclusion: PRP can exert a positive effect on human PDLFs,but this effect is concentration specific, while higher concentrations is not necessary to result in optimal outcomes.

AIM: To explore the effect of L-arginine (L-Arg) on the arrhythmia induced by ischemia/reperfusion (IR) of the right coronary artery in rabbits. METHODS: 48 healthy adult rabbits were divided into 4 groups (n=12 of each) randomly: IRa group (120 min reperfusion after 30 min ischemia), IRb group (120 min reperfusion after 120 min ischemia), IRa+L-Arg group and IRb+L-Arg group. I/R model was established by occluding and loosening the root of the right coronary artery in rabbits. The changes of ECG and arrhythmia were recorded and graded. RESULTS: ① The longer time of IR was, the higher the score of the arrhythmia was found. The incidence of atrial-ventricular block (AVB), sinus-atrial block (SAB), even sinus arrest were detected and aggravated gradually. ② The incidence of AVB was decreased and from Ⅲ?→Ⅱ?→Ⅰ? markedly, some of sinus and atrial arrhythmia were transformed into sinus rhythm gradually, and all of the arrhythmia scores in IRa group were decreased significantly as compared with the same time phases of IRb group (P

The interleukin-12 (IL-12) family, including IL-12, IL-23, IL-27,and IL-35, is characterized by unique structures and molecular partners.This is the only family of heterodimeric cytokines, which endows them with a unique set of connections and functional interactions.They not only play an important role in the regulation of inflammation, but are closely related to various autoimmune diseases.Here we discuss the structural aspects of these cytokines and their effect on some autoimmune diseases.
