Objective Through the research on relationship between achievement motive and personality traits,to provide the basis theory of personality attributes for selecting outstanding medical professional scientifically and effectively,and give some advice for improving medical education mode.Method The 310 medical staffs in sample hospital were treated as the research object in October 2015,who were randomly investigated with the big five personality questionnaire and achievement motivation scale,among of which,valid questionnaires were 290 copies leading to 93.5％ effective rate.SPSS 17.0 software was used to make t test,Chi-square analysis and correlation analysis for the data of the recover valid questionnaires.Result ①Personality traits of friendliness and rigor of the medical staffs of different gender exist statistically significant difference (t=-7.39,P=0.00;t=-8.28,P=0.00) and there were significant differences in the openness and rigor of medical staffs of different gender (P＜0.05).②The achievement motivation level of male medical staffs was higher than that of female (P=0.00),and there was no significant difference in achievement motivation among medical staffs.③The personality trait of neuroticism was negatively correlated with the pursuit of success and achievement motivation (correlation coefficient was-1.24),while the achievement motivation was positively related to extraversion and openness and the pursuit of success (the correlation coefficients were 1.51 and 1.53).Conclusion There is a significant correlation between personality traits and achievement motivation.The more extroverted personality medical staffs have,the more easy-going they are,and the more the pursuit of success oriented achievement motivation they have;and the higher the neurotic tendency individuals have,the more they incline to avoid failure of achievement motivation.

Objective To investigate the clinical effect of low frequency electrical pulse therapy combined with α-lipoic acid on diabetic gastroparesis in elderly patients with type 2 diabetes.Methods A total of 65 patients diagnosed as diabetic gastroparesis were selected from our hospital and divided into three groups according to random number table:the control group(n =23,the α-lipoic acid treatment),the conventional treatment group (n =16),and the experimental group (n =26,treating with α-lipoic acid combined with low-frequency electrical pulse therapy).All patients received the conventional diabetic therapy.Clinical effects,gastric emptying rate and serum gastrin(GAS) and fasting blood glucose levels were compared before versus after treatment among the three groups.Results The cure and total effective rates were higher in the experimental group than in the control group [46.15％ (12 cases) vs.30.43％ (7 cases),80.76％ (20 cases) vs.65.21％ (15 cases),x2 =0.867,P＜0.05].There were significant differences in gastric emptying rate,serum gastrin and fasting plasma glucose levels among the 3 treatment groups before versus after treatment.And the gastric emptying rate and serum gastrin level were better improved in the experimental groups compared with the conventional treatment and control groups.Conclusions The low-frequency electrical pulse therapy combined with α-lipoic acid has a significant clinical efficacy,which can improve clinical effects,promote gastric emptying,decrease fasting plasma glucose levels in elderly patients with type 2 diabetes.

AIM:ToinvestigatetheroleofMALAT1incolorectalcancermetastasis.METHODS:ThemRNA expression levels of MALAT1 and Rac1b in the tumor and adjacent normal tissues were examined by real-time PCR. MALAT1 was knocked down by siRNA in colorectal cancer cell lines .The expression of Rac1b and the epithelial-mesen-chymal transition markers was examined by Western blot .Cell proliferation was determined by EdU analysis .The effects of MALAT1 on the cell migration and invasion were examined by Transwell assay .RESULTS: The expression of MALAT1 was down-regulated in colorectal cancer .Down-regulation of MALAT1 induced Rac1b overexpression, which in turn in-creased the expression levels of E-cadherin and β-catenin.Furthermore, down-regulation of MALAT1 promoted the cell proliferation, invasion and migration.CONCLUSION:MALAT1 is associated with metastasis of colorectal cancer through regulating the expression of Rac1b and the downstream factors.

Objective To analyze the differences with the expression of glucocorticoids receptor isoforms ( GRα, GRβ, GRγand GR-P ) and cytokines [ IL-6, macrophage migration inhibitory factor (MIF), IFN-γand IL-10] between patients with systemic lupus erythematosus (SLE) and rheumatoid ar-thritis ( RA) , and to further understand their correlations with disease activities.Methods Fifty-five pa-tients with SLE, forty-nine patients with RA and thirty-eight healthy subjects were recruited in this study. All patients were steroid-naive.The expression of GRα, GRβ, GRγ, and GR-P in peripheral blood mononu-clear cells at transcript levels were determined by real-time PCR.Enzyme-linked immunosorbent assay was used to detect the expression of IL-6, MIF, IFN-γand IL-10 in serum samples.Results The percentages of GRαin all subjects were the highest among four isoforms of GR, followed by GR-P, GRγand GRβ.Com-pared with healthy subjects, patients with SLE or RA showed significantly decreased expression of GRα( P<0.05), but increased expression of GR-P (P<0.05).The percentages of GR-P in patients with RA were higher than those in patients with SLE (P<0.05).The expression of GRαwas negatively correlated with SLE disease activity index (SLEDAI) and disease activity score 28 (DAS28).SLE or RA patients with high disease activity showed lower expression of GRαthan those with low disease activity.The levels of IL-6, IFN-γand MIF in patients with SLE or RA were significantly higher than those in healthy subjects ( P<0.05).A negative correlation was observed between the expression of IL-6 and GRαin patients with SLE (P<0.05).The expression of IFN-γwas negatively correlated with GRαin patients with RA (P<0.05). Conclusion There were significant differences with the expression of GR isoforms among patients with SLE, patients with RA and healthy subjects, indicating the change of internal environment in patients might be in-volved in GR alternative splicing.GRαwas the predominant isoform and was negatively correlated with dis-ease activities.Oversecretion of cytokines resulted in a decreased expression of GRα.This study would be useful for the diagnosis of the disease status and for monitoring clinical treatment.

Objectives To explore the correlation between the population characteristics of sero-reactivity with quantitative antibody based-IHA and the transmission parameters,such as epidemic situation,transmission status or infection trend in population.Methods The residents in one endemic administrative village were simultaneously examined by Kato-Katz technique for parasitological stool examination,as well as by immuno-diagnostic technique IHA for detection of IgG antibody against soluble egg antigen for two consecutive years.The results of examination were analyzed and compared on the diagnostic parameters of IHA,the correlation of the changes of positive rates and antibody levels of IHA with the changes of infection trend in population and the distribution of antibody levels between 'the true negative' and 'the true positive'.Results When Kato-Katz technique based on 2 stool samples,each read in 3 thick smears,was used as the reference,the overall sensitivity of IHA was high (from 77.27% to 85.48%) with a relatively poor specificity of lower than 60%,the negative predict value (NPV) was excellent of higher than 94%.The specificity of IHA decreased with the increase of the age in different age-groups of population,showing the highest among the younger less than 15 years old.The distribution trends of positive rates of antibody in different age groups by IHA showed similar to that of egg positive rate detected by Kato-Katz although the positive rates of IHA were higher than these by Kato-Katz,which showed that a higher false positive (from 41.90% to 44.56%) and a certain false negative (from 14.52% to 22.73%)existed in IHA.The positive rate of antibody decreased slowly among the individuals with S.japonicum infection,who received treatment.There was an overlap in the distribution of antibody levels between ' the true negative' and ' the true positive'.Conclusions Under the current schistosomiasis epidemic situation in China,IHA is valuable in the epidemiologic surveys.It should be of further deliberation applying IHA as the screening approaches for identification of target individuals for treatment or determination of the infection rate in community and IHA needs to be combined with the parasitological examination.

AIM To study the influence of Huangqi Powder (Puerariae lobatae Radix,Astragali Radix,Mori Cortex) on femur and tibia in rats with glucocorticoid-induced osteoporosis (GIOP).METHODS Thirty one-month-old male SD rats were divided into three groups by randomized block design,which were control group (normal saline),prednisone group (3.5 mg/kg prednisone acetate),Huangqi Powder group (clinical adult dosage).Experimental test was maintained for one hundred and twenty days.Double fluorochrome labeling with calcein was performed before necropsy;bone resorption and bone formation index were determined by using blood serum;the femur structural and material mechanics were analyzed by using bone biomechanics method.The cancellous bone of proximal tibial and the cortical bone of tibial shaft static parameter and dynamic parameter were analyzed by bone histomorphometry method.RESULTS Huangqi Powder had no obvious improving effects on bone biomechanics and bone static parameter,but could increas the area,width and number of the proximal tibia bone trabecular.Mark perimeter percentage and mineralization rate of deposition could be increased.CONCLUSION Huangqi Powder can significantly increase proximal tibia cancellous bone mass and enhance bone trabecula structure of glucocorticoid-induced osteoporosis rats.

Objective To investigate the clinical efficacy of combined use of calcineurin inhibitor in the treatment of lupus nephritis in induction or maintenance,which is resistant to mycophenolate mofetil.Methods Sixty-six cases of children with lupus nephritis were selected from February 2014 to September 2016 in Huazhong University of Science and Technology,Tongji Medical College Affiliated Wuhan Children's Hospital.The randomized method was used to divide them into the control group and the observation group randomly.Among them,31 cases in the control group were given glucocorticoid,cyclophosphamide combined with traditional medicine for treatment;35 cases in observation group were given glucocorticoid,mycophenolate mofetil,tacrolimus (calcine phosphatase inhibitor) multi-target therapy for treatment.The clinical effect of 2 groups before and after treatment were compared,and the incidence of adverse reactions in the treatment of 2 groups of children were compared.Results After treatment,the levels of systemic lupus erythematosus disease activity index (SLEDAI),serum creatinine and 24 h urine protein [(6.05 ± 1.04) scores,(45.08 ± 18.52) μmol/L,(0.96 ±0.30) g/L] in the observation group were lower than those in the control group [(11.09 ±2.33) scores,(95.33 ±36.74) μmol/L,(2.05 ±0.74) g/L],and the differences were statistically significant (t =3.097,3.356,3.871,all P ＜ 0.05).Serum complement C3,plasma albumin levels [(1.05 ± 0.28) g/L,(63.24 ± 12.98) g/L] were higher than those in the control group [(0.34 ±0.10) g/L,(35.45 ±6.74) g/L],and the differences were statistically significant (t =4.124,3.567,all P ＜ 0.05).After treatment,the levels of serum complement C3 and plasma albumin were significantly higher between 2 groups than those before treatment,the differences were statistically significant (all P ＜ 0.05).The incidence of adverse reaction (14.29％,5/35 cases) in the observation group was lower than that in the control group (38.71％,12/31 cases),and the difference was statistically significant (x2 =5.128,P ＜ 0.05).Conclusion Multi-target combination therapy and traditional cyclophosphamide therapy can effectively control lupus nephritis in children,but the clinical effect of multi-target combination therapy is better and the adverse reaction is less.

Objective To investigate the influence of murine cytomegalovirus on the expansion of CD+CD25+ Foxp3+ regulatory T cell (Treg) and the activation of CD4+ CD25+Foxp3 - effector T cell (TE) in vivo. Methods Forty-two BALB/c mice were intraperitoneally inoculated with appropriate amount ofMCMV Smith strain for establishing the model of infection, another 42 mice served as mocked-infected con-trois. Day 28 post MCMV infection was determined to be the demarcation point of the acute and chronic in- fection based on the viral load of major visceral organs. On day 1,3, 7, 14, 28, 45 and 60 post infection, splenocytes were prepared by means of routine method. The proportions of CD4+CD25+ Foxp3+Treg and CD4+CD25+Foxp3- activated TE in T lymphocyte were measured by flow cytometry. Results The propor- tion of CD+CD25+ Foxp3+ T cells in T lymphocytes was persistently suppressed since day 7 post infection, and fell to the lowest level on day 28 post infection (P <0.01), then zoomed and reached the peak value on day 60 post infection (P < 0.05). CD4+CD25+ Foxp3 - TE proportion was up to the highest on day 3 post infection(P < 0. 01), then suppressed and in significantly lower level since day 45 post infection (P < 0.05). Treg/CD+TE ratio was in lower level on day 3 to 14 post infection(P <0.05) ; but on day 45 and day 60 post infection Treg/CD+ TE ratio was markedly increased (P < 0.05). Conclusion MCMV infec- tion can increase the CD+CD25+Foxp3+ Treg proportion, and inhibit CD4+T cells activation in chronic in- fection phase, which is likely to suppress the function of antiviral immunity in the infected host to cause a persistent latent infection.
