Objective To study the changes of plasma growth hormone releasing peptide(Ghrelin)level and its influencing factors in patients with hyperthyroidism.Methods 55 patients with hyperthyroidism (observation group)and 55 healthy persons (control group)were selected.ELISA was used to detect plasma indicators before and after treatment.The level of body fat percentage,Ghrelin,S -TSH and FT3 ,FT4 of the two groups before and after treatment were compared,and the relationship between Ghrelin and FT3 ,FT4 ,percentage of body fat,plasma S -TSH was analyzed.Results Compared with the control group,the percentage of body fat,Ghrelin and S -TSH level in the observation group were lower,and FT3 ,FT4 levels were higher,there were significant differences between the two groups(t1 =5.021,t2 =9.628,t3 =23.054,t4 =29.325,t5 =28.967,P <0.05).Compared with before treatment,the body fat percentage,Ghrelin and S -TSH level of the observation group were higher after treatment,and FT3 ,FT4 levels were lower after treatment,the differences were statistically significant(t6 =5.282,t7 =8.651,t8 =21.835,t9 =27.126,t10 =26.855,P <0.05).The correlation analysis showed that FT3 and FT4 were negatively correlated with plasma Ghrelin level(r =-0.44,-0.39,P <0.05),the percentage body fat and S -TSH had positive relationship with plasma Ghrelin level (r =0.31,0.33,P <0.05).Conclusion The plasma Ghrelin level in the patients with hyperthyroidism is lower than healthy subjects,and its level is related with FT3 ,FT4 ,percentage of body fat and S -TSH,the detection of the above indicators has important value for the assessment of hyperthyroidism.

Objective To investigate the prognostic value of fever burden in traumatic brain injury (TBI) patients.Methods A retrospective analysis of 355 TBI patients admitted to the emergency department and intensive care unit from November 2010 to October 2012 was performed,and the Glasgow outcome scale (GOS) was followed-up 6 months after the injury.The patients were divided into two groups according to the GOS:good outcome group (4 to 5) and poor outcome group (1 to 3).Relevant clinical findings were studied by statistical description,logistic regression analysis,Spearman correlation analysis and ROC curve analysis.Results Fever burden level was continuously increased with the decrease of GOS from score 5 to 2,except for score 1 of GOS,which was corresponding to a significant lower fever burden.There were significant differences in age,pupil reactivity,Glasgow coma scale (GCS) and fever burden between two groups (P ＜ 0.05).Compared to the good outcome group,the poor outcome group was featured with more advanced average age (P =0.000),poorer pupil reactivity (P =0.000),lower GCS score (P =0.000) and higher fever burden level (P =0.000).Univariate logistic regression analysis suggested that age,GCS,pupil reactivity and fever burden level (OR 1.166,95％ CI:1.117-1.217) were associatedwith poor outcome.The fever burden level and the other independent prognostic predictors as age,GCS and pupil reactivity were further included in the multivariate logistic regression model,and the adjusted OR of fever burden level was 1.098 (95％ CI:1.031-1.169,P =0.003).ROC curve analysis showed the respective AUC for fever burden was 0.713 (95％ CI:0.663-0.760).The relevant analysis revealed a significant negative correlation between the fever burden and the GOS score (r =-0.376,95％ CI:-0.462--0.283,P =0.000).Conclusions Fever burden can be considered as an independent predictor of poor outcome of patients with TBI.The TBI patients with early onset of high levels of fever burden will have increased poor outcome risk.

Objective To investigate the risk factors of acute kidney injury following coronary artery bypass graft(CABG).Methods Twenty-six patients suffering from acute kidney injury following CABG as the patient group and 59 individuals without impairment of renal function as the control from January 2008 to September 2012 in the First People's Hospital of Yichang according to a retrospective case-control study and nonconditional multivariable Logistic regression analysis method..Results Among the 85 patients undergoing CABG,26 suffered acute kidney injury following CABG with a morbidity rate of 30.59％.Identified risk factors for acute kidney injury following CABG included pre-operative mederale-sever cardiac insufficiency,prolonged mechanical ventilation,prolonged stay in ICU and anemia before surgery.The identified independent risk factor of acute kidney injury following CABG was pre-operative mederale-sever cardiac insufficiency (OR =3.206,95％ CI:1.067-9.631).Condusion Pre-operative mederale-sever cardiac insufficiency was an independent risk factor of acute kidney injury following CABG.

Objective: To investigate the effects of Ala-Gln induced heat shock protein 70 (HSP70) expression on myocardial ifbrosis and connexin43 (Cx43) remodeling in experimental rats’ model.
Methods: A total of 32 SPF male SD rats were randomly divided into 4 groups:①Control group,②Model group, the rats received isoprenaline (ISO) 5m/(kg·d),③Intervention group, the rats received ISO+Ala-Gln 0.75mg/(kg·d),④Quercetin group, the rats received ISO+quercetin 100mg/(kg·d)+Ala-Gln+DMSO. n=8 in each group. All animals were treated for 7 days and killed in 4 weeks for relevant examinations. HE and Masson staining was conducted to observe myocardial ifbrosis, then calculate collagen volume fraction; immunohistochemistry was applied to measure myocardial HSP70 expression,
extracellular signal regulated kinase (p-ERK1/2) and Cx43 distribution, then conduct semi-quantitative analysis by speciifc soft ware.
Results: HE and Masson staining indicated that Control group had no obvious myocardial ifbrosis, Model group and Quercetin group had obvious ifbrosis, and Intervention group showed less ifbrosis than the other 2 groups, all P<0.01. The fibrosis level was similar between Intervention group and Control group, P>0.05. The myocardial HSP70 expression was similar among Control, Model and Quercetin groups, P>0.05, while HSP70 expression was signiifcantly higher in Intervention group than the other 3 groups, all P<0.01. The myocardial p-ERK1/2 level was lower in Intervention group than Model and Quercetin groups, all P<0.01. The myocardial Cx43 level was similar between Control group and Intervention group with linear distribution, while it was higher in Intervention group than Model and Quercetin groups with disordered distribution, all P<0.01.
Conclusion: Ala-Gln inducing the higher expression of HSP70, which may reduce myocardial ifbrosis in experimental rats, it could be because of HSP70 down regulating p-ERK1/2 expression and inhibiting ERK signaling pathway.

Introduction: In Malaysia, late stage presentation of breast cancer (stage III or IV) has been a healthcare problem that varies geographically throughout the country. This study aims to understand the factors influencing late stage of breast cancer at presentation among Malaysian women in Segamat Hospital, Johor, which is a district hospital. Methods: A retrospective descriptive study was conducted on secondary data of all newly diagnosed breast cancer women from 1st August 2011 to 28th February 2014. Secondary data includes age, ethnicity, marital status, family history, education level, occupation, presenting symptom, duration of symptom, tumour size, tumour pathology, tumour grading, oestrogen, progesterone and HER-2 receptor status were collected and analysed using SPSS version 20.0.0. Result: In total, data from 52 women was analysed and two women were excluded for incompleteness as these women defaulted. Late stage at presentation was 59.6% of all new cases (17.3%, stage III and 42.3%, stage IV). The commonest age group of all women diagnosed with breast cancer was in the 5th decade. Majority of them were Malay, married and housewives with no family history of breast cancer. The statistically significant factors associated with late stage at presentation include Malay ethnicity (p=0.019), presenting symptoms other than breast lump (p=0.047), and duration of breast lump more than 3 months (p=0.009). Discussion/Conclusion: The study demonstrated presentation at late stage of breast cancer is a major health concern among Malaysian women in district hospital. This may be attributed to different sociocultural beliefs, strong belief in complementary and alternative medicine, lack of awareness, and difficult accessibility to healthcare services.

Objective To study interleukin-23 (IL-23) levels in serum and dendritic cells of acute-on-chronic liver failure (ACLF) patients with chronic hepatitis B (CHB) and to explore its relationship with the prognosis.Methods Peripheral blood mononuclear cells and serum were collected from 40 ACLF patients with CHB (including survival group 27 cases and non-survival group 13 cases) and 26 healthy controls.Monocytes were induced to immature dendritic cell in vitro and TNF-α was added to induce dendritic cell maturation.IL-23 mRNA of dendritic cells was detected by real time polymerase chain reaction (PCR), and serum IL-23 level was measured by enzyme-linked immuno sorbent assay (ELISA).Differences among the parameters with normal distribution were compared using t test, those with non-normal distribution were compared using non-parametric Mann-Whitney U-test, and the relationship between two variables was assessed by Spearman′s rank correlation.Results International normalized rate (INR) and model for end-stage liver disense (MELD) scores in non-survival group of ACLF were higher than those in survival group (INR: 2.32 vs 1.64, U=69.00, P=0.002 2;MELD:36 vs 30, U=64.50, P=0.001 4).However, there were no significant differences between two groups at gender, age, alanin aminotransferase (ALT), aspartate aminotrans ferase (AST), bilirubin, creatinine, hepatitis B virus (HBV) DNA, hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and serum IL-23.IL-23 mRNA level in dendritic cells at baseline in non-survival group of ACLF was significantly higher than that in survival group (76 vs 43, U=71.50, P=0.002 8).After treatment, serum IL-23 was significantly declined in survival group ([160±75] ng/L vs [91±49] ng/L, t=4.012, P=0.000 2), but not in non-survival group.Significant positive correlation was observed between IL-23 mRNA level in dendritic cells and MELD score at baseline (r=0.7198,P<0.01).Conclusions Persistent high serum IL-23 level suggests poor prognosis in ACLF patients with CHB.IL-23 mRNA expression in dendritic cells has good consistency with MELD score and the patients with high IL-23 mRNA expression has poor outcome.
