Objective We established the animal models of obesity induced by high-fat diet, in order to study the mRNA and protein expression of regulation molecules related with iron metabolism about hepcidin, lipocalin-2 ( LCN2 ) , ferroportin-1 (FPN1) in obese mice’ s liver and the molecular regulation mechanism.Methods C57BL/6J (4 ~6 weeks) mice were randomly divided into control group and obesity model group, each group of ten.The obesity group were fed with a high-fat diet and the control group were given the normal diet for lasting 15 weeks.After we successfully established the obesity animal model, the expression level of hepcidin, LCN2 and FPN1 mRNA in the liver were measured by Real-time fluorescent quantitative PCR method and the protein expression level of LCN2 and FPN1 were measured by Western-Blot.Results Compared with the control group, the expression level of hepcidin mRNA in the liver was increased in obesity group (P <0.05), however, the expression level of LCN2, FPN1 was no significant difference (P >0.05).Conclusion Obesity can increase the expression of hepcidin mRNA, however, there was no significantly effect on the expression of LCN2, FPN1.So, we can’t think that obesity can affect the expression of LCN2 and FPN1, lead to the ability of cells uptake and release iron abnormal, then appear iron metabolism disorders.As a result, leading to iron deficiency.Maybe obesity can affect other regulatory molecules related with iron metabolism through up-regulation the expression of Hepcidin or the more complex regulatory mechanisms.We still need further experimental research and exploration.This research also provides the basis of theoretical and experimental for the further study the effects of obesity on the expression of regulation molecules related with iron metabolism in obesity mice’ s liver and the mechanism of iron deficiency.

Objective To investigate the risk factors for postoperative nausea and vomiting (PONV) in spinal anesthesia patients.Methods A total of 841 patients received spinal anesthesia were visited after operation.Data were analyzed using univariate analysis and multivariate Logistic regression to identify risk factors related to PONV.Results PONV occurred in 94 patients (11.2％,94/841).Univariate analysis showed that PONV was unrelated with gender,age,ASA classification,anesthesia mode (P ＞ 0.05),related with operation department (P =0.026),body mass index (P =0.020),education level (P =0.000),history of previous surgery anesthesia (P =0.005),history of PONV (P =0.000),history of kinesia (P =0.002),smoke (P =0.019),intraoperative using of tramadol (P =0.018).Multivariate analysis showed that operation department (OR =4.039,95％ CI 1.331-12.259,P=0.048),education level (OR =3.504,95％ CI 1486-8.260,P=0.015),history of PONV (OR =5.113,95％ CI 1.790-14.606,P =0.002),intraoperative using of tramadol (OR =5.316,95％ CI 1.091-25.908,P =0.039) were identified as independent risk factors for PONV.Conclusions The independent factors associated with PONV following spinal anesthesia include operation department,education level,history of PONV,intraoperative using of tramadol.Identifying patients who are at high risk for PONV will enable the formation of more timely management project.

Objective To understand the association between rs1079727 polymorphism in the DRD2 gene and the distractibility in the school-age children.Method The rs1079727 polymorphisms were genotyped using Sequenom Mass Array and the distractibility was measured based on the Middle Childhood Temperament Questionnaire (MCTQ) in 121 children aged from 8 to 12 years,in order to analyze the function of rs1079727 polymorphism and its interaction with gender or the delivery mode on the distractibility.The results were analyzcd with oneway ANOVA and logistic regression analysis.Results There was association between the distractibility and rs1079727 polymorphism or delivery mode respectively.The means of distractibility for the genotypes of GG (4.37 ±0.53) and AG (4.27±0.69) were significantly higher than that of the genotype of AA(4.01±0.67) (P＜0.05).The proportion of high distractibility in the cesarean children (48.28％) was significantly higher than that in the natural labor children (33.90％) (P＜0.05).The child distractibility occurred through an interaction between rs1079727 polymorphism and gender/delivery mode.The girls with G alleles possessed increased risk of distractibility (OR=2.231,P＜0.05),and the natural labor children with A alleles were tend to be associated with low distractibility(OR =0.048,P＜0.01).Condusion The distractibility based the temperament for the school-age children might be influenced by delivery mode,rs1079727 polymorphism and its interaction with gender/delivery mode.

[Objective] To establish a determination method for isolated gastrointestinal intra-cavity perfusion pressure and to explore its application in pharmacological experiment. [Methods] Determination method for isolated gastrointestinal intra-cavity perfusion pressure was established according to motility of the isolated rat gastric muscle strip and water-sac perfusion manometry and ileum peristalsis of Guinea pigs. Intra-cavity pressure of isolated gastrointestinal canal of rat and guinea pig was observed. [Results] Gastric intra-cavity pressure was markedly increased as added with various doses of acetylcholine (1.25, 2.5, 3.25, 5, 6.25 and 7.5 ?g/mL respectively) in nutrient solution. The ileum intra-cavity pressure was also increased as added with various doses of histamine (0.125, 0.25, and 0.5 ?g/mL respectively) . The effects were in a dose-effect manner and the differences were significant as compared with distilled water group ( P

0.05).Conclusions The patients with sepsis lasting more than 7 days had high mortality (50%). While percentage of CD14 and CD14MFI of peripheral blood are increased,the total scores of SOFA and numbers of MOF are decreased.The improvement of monocytes function indicates good prognosis. The changes of expression of ICAM-1,serum TNF-? and IL-10 can not reflect prognosis in septic patients.

Objective:This study investigated the clinical characteristics of multiple myeloma with early death in the era of novel drugs. Methods:Medical records from 188 patients diagnosed from January 2009 to December 2015 were retrospectively reviewed, showing that early death occurred in 19 patients. Early death was defined as death by any cause within the first year after diagnosis. Results:(1) Early mortality was 10.1%, and the median age was 67 years old (range:40-84 years). Eight cases presented IgG type, and 11 cases were non-IgG type. All 19 patients were diagnosed to be at stageⅢin accordance with the Durie–Salmon staging system, and renal insufficiency occurred in 10 patients. In accordance with the International Staging System (ISS), four patients were diagnosed to be at stageⅡ, whereas 15 other patients were at stageⅢ. Extramedullary plasmacytoma (EMP) occurred in six cases, whereas 10 cases pre-sented high-risk patients with cytogenetic abnormalities. Elevated lactate dehydrogenase (LDH) was found in five cases, amyloidosis was detected in three patients, and secondary plasma cell leukemia was observed in two cases. The median score of performance sta-tus (KPS) was 70 (range: 20-80). A total of 16 patients were treated with bortezomib, and 3 patients were treated with CADT. (2) Among the 13 patients who were evaluated, the overall response rate was 46.2%(6/13), and the complete response (CR) and near-CR rate was 7.7%(1/13). (3) The median overall survival was 3 (1-11.5) months, although the two patients with secondary plasma cell leu-kemia survived for less than 2 months. (4) Eight patients died of disease progression (42.1%), eight patients died of severe infections (42.1%), and three patients died of thrombotic events. Conclusion:The important causes of early death include the following:high-risk cytogenetics, elevated LDH, EMP, amyloidosis, advanced age, poor performance status, and serious complications during treat-ment. In the era of novel drugs, we should improve early diagnosis rates and explore individualized treatment for high-risk multiple my-eloma for the benefit of a wide range of patients.

Objective To understand the prevalence and epidemiological features of clonorchiasis sinensis based on inpa-tients in Zhongshan City. Methods All of the 23 town hospitals in Zhongshan City were selected as the surveillance hospitals in 2016. Among the inpatients from those hospitals,those lived in the city longer than 6 months were selected as the surveillance subjects. The stool specimens of the subjects were collected and examined by the modified Kato-Katz thick smear method for the eggs of Clonorchis sinensis. The crude infection rates of C. sinensis of the subjects were standardized according to the age and sex compositions of the population in Zhongshan City,2016. Meanwhile,the infection rates of the subjects from different towns and those combined with related clinical diseases were analyzed. Results A total of 2667 people were included in the surveil-lance,among which 219 were tested as positives,with a crude infection rate of 8.21％. For the positives,the male accounted for 81.74％(179/219),and their age ranged from 4 to 89 years with the mean value of(62.20±13.80)years. After standardization by age and sex composition,the infection rate was 3.62％for the whole population,the rates of the male and the female were 5.46％and 1.53％,respectively,and the former was 3.57 times as high as the latter. Both the infection rates of the male and the female rose as the age increasing(χ2 male=99.91,χ2 female=16.51,both P<0.01). The standardized infection rates among the subjects in different towns ranged from 0 to 10.40％,and the rates in the north towns were higher than those in the south towns. The standardized rate was 9.22％for the subjects combined with gallstone,3.40％for those not combined with gallstone,and the former was 2.71 times as high as that of the latter. Conclusion The people aged 30 years and above,with gallstone or living in towns with high C. sinensis infection rates are the key population for prevention and control of clonorchiasis in Zhongshan City.

Objective To investigate the effect of clinical pathway on inpatients for rehabilitation. Methods The hospital expense, the ex-pense for medicine and length of stay in hospital were compared in patients with cerebral hemorrhage, cerebral infarction, spinal cord injury and spastic cerebral palsy before (January 1st, 2012 to April 30th, 2013) and after (May 1st, 2013 to December 31st, 2015) clinical pathway implementation, 50 inpatients for each disease, totally 200 patients. Results The length of stay in hospital reduced after of clinical pathway implementation, in all the diseases (t>5.226, P<0.001), with the decrease of hospital expense for cerebral infarction (t=3.327, P<0.001). There was no significant increase in any expense in the disease (t<1.777, P>0.05). Conclusion The implementation of rehabilitation clinical pathway can reduce the length of stay in hospital for the patients rehabilitation in hospital, without increasing their cost.
