ObjectiveTo measure levels of serum resistin in patients with nonalcoholic fatty liver disease (NAFLD) and explore the relationship between serum resistin and insulin resistance,and the role of serum resistin in the pathogenesis and progression of NAFLD.Methods 53 patients (including 30males and 23 females) with NAFLD and the 28 control subjects (including 16males and 12females) were enrolled in this study.The height,weight,waist circumstance,hip girth and blood pressure of all subjects were obtained by standard methods.To all the subjects,the parameters including fasting blood glucose (FBG),triglyceride ( TG),total cholesterol (TC),high-density lipoprotein cholesterol ( HDL-c ),lowdensity lipoprotein cholesterol ( LDL-c ),alanine aminotransferase ( ALT),aspartate aminotransferase (AST)and gamma glutamyl transferase (GGT) were measured.Serum resistin was measured by electrochemiluminescence immunoassay (ECLIA) and fasting serum insulin (FINS) were measured by enzymelinked immunosorbent assay (ELISA).Body mass indexes (BMI),waist hip ratio (WHR),body fat percentage ( BF％ ) were calculated with formula.Homeostasis model assessment was applied to assess the status of insulin resistance index (HOMA-IR).The relationships between serum resistin and various parameters in patients with NAFLD were observed and analyzed by statistical methods.ResultsThere were no significant differences in the number of cases,average age,compositions of sex and BF％ between the NAFLD group and the control group ( P ＞ 0.05).In the NAFLD group,systolic blood pressure ( SBP),diastolic blood pressure(DBP).The waist circumference,hip girth and BMI and WHR were higher than those of control group ( t =3.54,3.32,3.56,5.85,5.56,4.10,P =0.001).There were no significant differences on the level of TC,HDL-c,LDL-c between the NAFLD group and the control group ( P ＞0.05).In the NAFLD group,FBG,TG,AST were higher than those of control group ( P =0.001,P =0.004,P =0.001 ).The levels of serum resistin,FINS,HOMA-IR,ALT and GGT in NAFLD group were significantly higher than those of control group,and there was significant difference between two groups ( P =0.0005).There was no significant correlation between serum resistin and age,BMI,WHR,BF％,FBG,TG,TC,HDL-C,LDL-C,AST in NAFLD group ( P ＞ 0.05).The levels of serum resistin in patients with NAFLD were positively correlated with GGT,ALT,FINS,HOMA-IR ( r =0.354,0.391,0.875,0.881,P ＜0.05 or ＜0.01 ).After multiple stepwise regression analysis,the results showed that HOMA-IR was the most important factor for affecting the levels of serum resistin.The levels of serum resistin in male and female patients with NAFLD were higher than those of control group ( P ＜0.05).But no statistical difference was found between males and females in two groups ( P ＞ 0.05).ConclusionsThe levels of serum resistin in patients with NAFLD were significantly higher than those of controls.Serum resistin in patients with NAFLD was closely correlated with insulin resistance,and it may participate in the pathogenetic progress of NAFLD.Serum resistin in patients with NAFLD might be associated with hepatic insulin resistance,and it has no correlations with obesity-related insulin resistance.Serum resistin in patients with NAFLD may participate in the inflammation of fatty liver disease as inflammatory cytokines.

Objective To investigate the clinical significance of serum lactic dehydrogenase (LDH)alteration in patients with acute leukemia (AL). Methods Serum LDH of 156 AL patients including untreated 63,completely remission (CR) 46 and relapsed 47 were measured by biochemistry analyzer. R banding technique was used for karyotype analysis this three groups were divided according to poor, good and normal prognostic chromsome. The correlation between LDH level with AL periods, chromsome groups, peripheral WBC counts and leukemia subtypes were analysed. Results The LDH level of AL patients untreated (P50 399 U/L) and relapsed (P50 265 U/L) were significantly higher than those CR (P50 153 U/L), P ＜0.05. LDH level were closely correlated with peripheral WBC counts (rs=0.604) and leukemia cells of bone marrow (rs=0.538, both P ＜ 0.01), and both were also correlated with leukemia subtypes (LDH in subtypes L2, M4 were higher than other subtypes of AL, P ＜ 0.01). The refractory and relapsed AL patients had higher LDH level (P50 538 U/L) than the others (P50 294 U/L) when they were diagnosed. And those with poor prognostic chromsome also had higher LDH level (P50 778 U/L) than those with good (P50 306 U/L) and normal prognostic chromsome (P50 405 U/L, P ＜0.01). Conclusion LDH level increased obviously in untreated AL patients and decreased in CR ones. It was correlated with different periods, subtypes and grade malignancy of AL So LDH level can be considered as an important indicator for therapeutic effects and prognosis for AL patients.

Tumor stem cells have abilities of high proliferation,serf-renewal and multi-directional dif-ferentiation ;which is closely responsible for tumor' s survival and recurrence. A minor portion of myeloma stem cells exist in multiple myeloma. The research of myeloma stem cells' origins, phenotypic analyses, signaling pathways, drug resistance and other biological characteristics will do great efforts to the effective therapy of mul-tiple myeloma.

Objective To study the urodynamic characteristics of women with pelvic organ prolapse in prolapse and reset condition. Methods From Jan. 2010 to Apr. 2010, 30 patients with pelvic organ prolapse (POP), including 1 case in grade Ⅰ , 6 cases in grade Ⅱ , 21 cases in grade Ⅲ and 2 cases in grade Ⅳ, treated in Peking University People's Hospital were analyzed their urodynamical changes at status of prolapse and reset with pessary. Results (1)The symptoms: in the prolapse condition, there were 11 patients with bladder outlet obstruction( BOO), 7 patients with residual volume more than 100 ml, and 4 patients with stress urinary incontinence(SUI). In the reset condition, there were 5 patients with BOO,5 patients with residual volume more than 100 ml, and 4 SUI patients. (2) Characteristics of urodynamic:there were significant difference in first desire to void ( FD, P = 0. 047), normal desire to void ( ND, P =0. 007), strong desire to void ( SD, P = 0. 001 ), maximum cystometric capacity ( MCC, P = 0. 001 ),maximum flow rate ( Q=max, P = 0. 001 ), average flow rate ( Q P = 0. 001 ), and residual volume ( RV,P = 0. 025 ) between prolapse and reset condition among all patients. In patients with grade Ⅰ to Ⅱprolapse, Qmax were (11 ±6) ml/s in prolapse condition and (15 ±4) ml/s in reset condition (P =0. 014), Qave were ( 6 ± 4 ) ml/s in prolapse condition and ( 7 ± 3 ) ml/s in reset condition ( P = 0. 237 ),RV were (29 ±46) ml in prolapse condition and (15 ±25) ml in reset condition (P =0. 157). Among patients with grade Ⅲ to Ⅳ prolapse, Qmax were ( 11 ± 8 ) ml/s in prolapse condition and ( 17 ± 10) ml/s in reset condition (P=0.001), Qave were (5 ±4) ml/s in prolapse condition and (7 ±4) ml/s in reset condition ( P = 0. 002 ), RV were ( 105 ± 169 ) ml in prolapse condition and (47 ± 92) ml in reset condition (P = 0. 037 ). Conclusions Patients with pelvic organ prolapse Ⅲ - Ⅳ may present pseudo BOO,recessive stress urinary incontinence and residual volume more than 100 ml. There were significant improvement in cystometric sensation, capacity, flow rate, and residual volume after reset. The urodynamic test for patients with pelvic organ prolapse in the reset condition might be much better in evaluating lower urinary tract function.

Objective:To investigate the sleep quality of the people aged over 18-years-old in Hebei province and the impact of relative factors on it.Methods:Sum total of 20 716 random samples at ages over 18 were selected among the general population.The tools were Pittsburgh Sleep Quality Index(PSQI),Simplified Coping style Questionnaire(SCSQ).Results:The total prevalence of low sleep quality was 11.6 %(2411/20716).Female had higher standardized prevalence rate than male(6.8% vs.4.8%).Logistic analysis showed that risk factors to low sleep quality were ages over 70-years-old,remarriage,divorce,bereft,negative coping style(OR=1.776,1.515,2.046,1.254,1.097).On the other hand,factors to good sleep were the Han nationality,male,farmer,the family average annual income ranged 5001-10000 RMB,10001-20000 RMB,20001-40000 RMB,positive coping style(OR=0.839,0.703,0.732,0.750,0.660,0.573,0.936).Conclusion:Low sleep quality had high prevalence in Hebei.It should be recognized by medical workers.

Objective To investigate the variability of serum Cystatin C concentration and urinary Cystatin C concentration in primary glomerulonephritis patients of different patological types,and to study the correlation with renal pathological changes. Methods Urinary Cystatin C was detected before renal biopsy.The two indexes were processed by correlation analysis with glomcrulus scores and renal tubulointerstitial scores respectively.Results The differences of Serum Cystatin C concentration and urinary Cystatin C concentration in IgA nephropathy(IgAN) group,focal segmental glomerulosclerosis group and membranous nephropathy group existed statistical significance as compared to normal control (P

ObjectiveTo investigate and analyze the prevalence and risk factors of acute stress disorder (ASD) among survivors of road traffic accidents.MethodsA total of 206 participants ( 168 men,38 women) were administrated with the acute stress disorder scale (ASDS) 2 to 23 days after the traffic accidents.ResultsThere was a total of 61 (29.6％) possible ASD patients among all participants.Women had more serious ASD symptoms than men (male:36.70 ± 11.42; female:41.18 ± 12.58; P＜ 0.05 ),the married's ASD symptom severity was higher than the single's ( married:38.37 ± 11.94 ; single/widowed/divorced:30.86 ± 8.37 ; P ＜ 0.01 ),people with low degree of education had more severe ASD symptoms than the people who had high degree of education (P＜0.05) ; being elder( r=0.43,P＜0.01 ),having fear / helpless / horror experience of accident ( r=0.21,P＜ 0.01 ) were significantly correlated with the severity of ASD symptoms.According to linear regression analysis,age could positively predicted ASD symptoms ( β =0.29,P ＜ 0.01 ) too.ConclusionASD is a common mental problems among Chinese survivors of road traffic accident,and the main predictive factors of ASD include gender,age,marital status,the degree of education,whether there is fear / helpless / horror experience of accident.

Objective To investigate the features of patients with cyclic citrullinated peptide (CCP) antibodies in primary Sj(o)gren's syndrome (pSS) with the retrospective method.Methods Seventy eight pSS patients were studied.Enzyme-linked immunosorbent assay (ELISA) indirect immunofluorescence was used to measure anti-CCP antibodies.The patients with and without anti-CCP antibodies were correspondingly classified as autoantibody-positive and negative pSS groups.Clinical and laboratory features were compared between autoantibody-negative and positive group.Results (1) Seven (9.0％) of pSS patients had positive anti-CCP antibody.No significant difference was found in sex,ages,and disease course between autoantibody-nagative and positive pSS patients.(2) The anti-CCP-positive pSS was associated with the rates of decayed tooth,fatigue,dry mouth,dry eyes,and tender of joint (P ＜ 0.05).Whereas,the antiCCP-negative pSS was not significantly related to fever and mumps (P ＞ 0.05).(3)From serologic characteristics aspects,the anti-CCP-positive patients showed higher level of tender of joint than the anti-CCP-negative patients.No significant difference was found in white blood cell (WBC),hemoglobin (HGB),platelet (PLT),erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),immunoglobulin A (IgA),IgG,IgM,and rheumatoid factor (RF) between two groups (P ＞ 0.05).Conclusions The anti-CCP-positive patients were 9％ ofpSS patients,and were more likely to occur tender of joint with higher level of tender of joint.

Objective To investigate couple's personality similarity effect on the marital quality,and to explore the vairance of such effect under different levels of spouse's depression. Methods The cross?sectional da?ta of 4644 couple from the national survey of mental health database in china( 2009) was used. Couples completed Locke ?Wallance marital adjustment test,The CES?D scale a self?report depression scale and Eysenck personality questionnaire short scale for Chinese version (EPQ?RSC). Results The personality similarities of couples(0.44 ±0.27) and their marital quality (wife (103.71±27.54),husband (106.15±26.94))had significant positive corre?lation ( r=0.25~0.27, P<0.01). Regression analysis showed the effect of personality similarity on the marital quality were varied according to the level of spouse depression( β=0.09?0.22, P<0.05) . Among participants whose husband or wife had higher level of depression,couple's personality similarity had stronger effect on his/her per?ceived marital quality. Conclusion Husband and wife personality similarity is related to marital quality signifi?cantly,and the spouse depression plays a significant moderating role in this relationship.
