Objective To discuss the anatomical and radiographic characteristics of acetabular fossa,and evaluate their value as a reference for achieving the anticipated inclination of the acetabular cup.Methods Sixteen adult normal pelvic specimens were studied.Central axis of acetabular fossa and its intersection with fossa edge and acetabular rim were marked.The radiographic appearance of the two intersections was evaluated.With radiographic templating,the relationship between the top of acetabular fossa and the central axis of acetabular cup at anticipated inclination was identified.Implantation of cementless acetabular cup was performed bilaterally on the pelvic specimens.The acetabular fossa was used as a reference for implantation on one side,and the acetabular positioning device was used on the other side.The discrepancy of acetabular inclination was recorded before and after operation in the two groups.Results Intersection of central axis of acetabular fossa with fossa top edge and acetabular rim corresponded to the most medial and lateral aspect of acetabular sourcil respectively on standard anteroposterior pelvic radiograph.There was close correlation between most medial aspect of acetabular sourcil and central axis of the acetabular cup at anticipated inclination of 40°±5°.For the group of using acetabular fossa as reference,the mean difference of inclination was 0.19°±3.14°(-6°-5°)before and after operation,and the discrepancy was 2.75°±2.89°(-2°-8°)for the control group.The difference between the two groups was statistically significant(t=-2.453,P=0.027).Conclusion In primary total hip replacement,if normal anatomy of acetabulum was found,the anticipated inclination of acetabular cup can be accurately obtained,based on the relationship between the top of acetabular fossa and anticipated inclination of acetabular cup on preoperative templating.

Objective The aim of this study is to evaluate clinical application of BODE (body mass index, airflow obstruction, dyspnea, and exercise capacity) index in patients with chronic obstructive pulmonary disease (COPD). Methods Forty patients with stable COPD in Xuanwu Hospital of Beijing during September 2003 to December 2007, were recruited in the study, including 25 men and 15 women, aged 38 to 85 years (with a mean of 62 ± 13 years). BODE index was measured for each patient, one year and three years after recruitment, respectively. Severity of COPD, including number and duration of episodes, length of each hospital stay and times of hospitalization due to acute exacerbation of COPD (AECOPD), were recorded. All data were statistically analyzed with SPSS 13.0 software for windows. Results ①There was a remarkable difference in COPD severity between patients with BODE score equal to or greater than five and these with less than five (P <0.01 ). ①BODE score inversely correlated with forced expired volume at the first second ( FEV1 ) in COPD patients (P < 0.01 for those with BODE score equal to or greater than five and P <0.05 for these with BODE score less than five, respectively). ③BODE score positively correlated with number and duration of acute exacerbation, length of hospital stay and times of hospitalization due to AECOPD (P <0. 01 for those with BODE score equal to or greater than five and P < 0. 05 for those with BODE score less than five, respectively). For patients with COPD, their BODE score in the first year positively correlated with that in the third year ( r = 0.834, P < 0.01 ). Conclusions BODE index is a better indicator to evaluate their condition severity in patients with COPD.

Objective To explore the relationship between the change in waist circumference (WC) and new onset diabetes (NOD) in a population of north China.Methods A total of 101510 subjects took part in the health examination from 2006 to 2007 for the employees of Kailuan Group.89364 subjects with fasting plasma glucose (FPG) ＜7.0 mmol/L,no history of diabetes,with complete data of FPG and WC,and without taking hypoglycemic agents were sclected as the observation cohort.Subjects who did not participate in the health examination from 2010 to 2011 and had incomplete data were finally excluded and thus 58426 subjects were included for final analysis.According to the baseline WC measurement and its quartile in the health examination during 2006 to 2007,the observed population was divided into two groups (obese group and non-obese group) or four groups ( first,second,third,and forth quartile groups).Multiple logistic regression analysis was used to test the relation between the change in WC and NOD.Results ( 1 ) The incidence of NOD in obese group was higher than that in non-obese group (8.02％ vs 3.37％,P＜0.01 ).Along with increasing WC in the 4 quartile groups,the incidence of NOD was progressively increased,being 2.32％,3.62％,5.46％,and 8.89％ respectively in the total population ( 2.84％,3.65％,5.32％,and 8.95％ in male,and 1.50％,3.41％,6.22％,and 8.51％ in female).( 2 ) Multiple logistic regression analysis showed that compared with the first quartile group,the second,third,and forth quartile groups had increased risks of NOD after adjusting age,gender,and other risk factors,the OR value being 1.17,1.47,and 1.95,respectively.After adjusting above factors in different genders,the influence of the second group on NOD in males and females was not significant,however,they still increased the risks of NOD,with the OR value being 1.08,1.36,and 1.90 in male,and 1.35,1.70,and 1.88 in female,respectively.Conclusion The incidence of NOD is increased with increasing WC.

The association between CXCL5 gene polymorphism and obese patients with type 2 diabetes mellitus (T2DM) was explored.The distribution of CXCL5 gene promoter region-156G/C polymorphism revealed no significant difference between normal control group and T2DM group (P＞0.05).The frequency of C allele gene in obesity group was higher than that in non-obesity group(P＜0.05).The results suggest that the CXCL5 promoter gene -156G/C polymorphsim has no relation with T2DM,but it is a risk factor for obesity.

ObjectiveTo study the relationship between fasting plasma glucose (FPG) level and the first cerebral infarction event in the population with diabetes.Methods This was a prospective cohort stndy.8 306 diabetic subjects who determined FPG ≥ 7.0 mmol/L or treated with insulin or hypoglycemic drugs and FPG ＜7.0 mmool/L as the observation population and were followed-up for (48.01 ± 3.14) months.During the course,cerebral infarction events were determined every 6 months.Results( 1 ) By the end of following-up,with the increasing levels of the baseline FPG,the total cholesterol (TC),triglyceride (TG) levels were gradually increased in the diabetic population,the differences were significant [ TC:( 4.93 ± 1.15,5.10 ± 1.20,5.15 ± 1.28,5.33 ± 1.35 ) mmol/L,TG:( 1.70 ± 1.26,1.83 ± 1.29,2.18 ± 1.76,2.41 ± 2.08 ) mmol/L,P＜0.05 ] ; the plasma low density lipoprotein-cholesterol (LDL-C),systolic blood pressure ( SBP),diastolic blood pressure ( DBP),and body mass index (BMI) levels were also increased significantly ( P＜0.05 ).(2) The ineidence of cerebral infarction event in the group of patients with 7.0 mnol/L ≤ FPG ＜ 9.0 mmol/L was the lowest,the differences were significant ( 2.1％,P ＜0.01 ).Compared with the group of 7.0 mmol/L≤ FPG＜9.0 mmol/L,after adjusting for age,sex,BMI,SBP,DBP,TC,TG,low density lipoprotein-cholesterol,high density lipoprotein-cholesterol,smoking,diabetic duration and treatment,the relative risk for cerebral infarction events were 1.85 (95％ CI 1.09-3.15,P＜0.05) and 1.54 (95％CI 1.16-2.05,P ＜ 0.01 ) for those groups with 6.1 mmol/L ≤ FPG ＜ 7.0 mmol/L and FPG ≥ 9.0 mmol/L respectively.ConclusionThe risk of new in cidence of cerebral infarction events seems to be the lowest in the group of diabetic patients whose FPGs are wihin 7.0-9.0 mmol/L range.

Objective To investigate the possible mechanism of natural killer cells(NK cells)in immune dysfunction in sepsis by monitoring the phenotype and function of periphery NK cells in patients with sepsis. Methods A retrospective study was conducted. The patients with systemic inflammatory response syndrome(SIRS,n=59)or sepsis(n=65)admitted to Department of Critical Care Medicine of Anhui Provincial Hospital from August 2011 to August 2013 were enrolled. Blood samples were collected within 48 hours after intensive care unit(ICU)admission,the phenotype and function of periphery NK cells were determined by flow cytometry. Twenty-eight healthy people served as controls. Results The proportion and number of peripheral blood CD3-CD56+NK cells in SIRS and sepsis groups were normal,and no statistical difference was found when compared with those of the healthy control group〔cell proportion:0.102±0.019,0.102±0.108 vs. 0.106±0.018,F=0.018,P=0.982;cell number(×106/L):182.46±65.98, 172.97±63.51 vs. 179.25±60.44,F=0.349,P=0.706〕. It was shown by NK cell degranulation detection that there was no significant difference in the expression of CD107 and interferon-γ(IFN-γ)secretion〔CD107:0.135±0.050,0.140±0.058,0.128±0.070,F=0.583,P=0.560;IFN-γ(kU/L):14.36±4.74,12.49±4.21, 13.45±5.04,F=1.616,P=0.202〕among healthy control group,SIRS group,and sepsis group. It was shown by antibody dependent cytotoxic effect(ADCC)test that there was no difference in the expression of CD107 among healthy control group,SIRS group,and sepsis group(0.574±0.166,0.643±0.165,0.581±0.157,F=0.808,P=0.448). When compared with healthy controls,the secretion of IFN-γwas increased in SIRS patients(kU/L:40.5±13.2 vs. 28.4±9.6,P=0.001),while reduced in sepsis patients(kU/L:19.8±6.7 vs. 28.4±9.6,P<0.01). Compared with SIRS group,only NK cell surface inhibitory receptors CD158e(KIR 3DL1)expression in sepsis group was significantly increased(0.203±0.057 vs. 0.079±0.021,t=15.762,P<0.001),and there were no significant differences in the other phenotype between the two groups. Compared with SIRS group,the IFN-γproduction of the sepsis group was significantly lowered(kU/L:0.280±0.040 vs. 0.310±0.038,t=3.390,P=0.009),and the level of IL-12 was also significantly decreased(ng/L:0.15±0.03 vs. 0.30±0.08,t=32.832,P<0.001). Conclusion It was showed by NK cell phenotype and function assay that the function of NK cells in patients with sepsis was impaired and led to a poor production of IFN-γ. The IFN-γmediated immune dysfunction may be a main reason for the disorder of NK cell function,which laid the foundation of the clinical immune intervention practice to improve to NK cell function.

Objective To investigate the expression of miRNA associated with hepatic fibrosis induced by Schistosoma ja-ponicum soluble egg antigen stimulation in mouse hepatocytes(AML12),so as to lay the foundation for clarifying the mecha-nism of schistosome infection leading to hepatic fibrosis. Methods The expressions of miR-122,miR-182,miR-23b,miR-27b and KSRP in AML12 cells treated with SEA were measured by q-PCR. KSRP protein in cell lyses was measured by Western blotting. AML12 cells were transfected with miR-27b precursor or anti-miR-27b for 24 h,then q-PCR was adopted to determine KSRP mRNA,and KSRP protein was detected by Western blotting. Results The expressions of miR-182,miR-23b and miR-27b were decreased and miR-122 was increased in AML12 cells following SEA treatment(all P<0.05). An increase of mRNA and protein of KSRP expression was also observed in AML12 cells after SEA stimulation(both P<0.05). In addition,KSRP mRNA expression was not changed significantly in AML12 cells transfected with anti-miR-27b or miR-27b precursor,and miR-27b precursor reduced KSRP protein expression as compared with the control. In contrast,the expression of KSRP protein was increased in the anti-miR-27b group and decreased in the miR-27b precursor group. Conclusions After the stimulation of SEA,the expressions of a variety of liver fibrosis-related miRNAs and KSRP change in murine hepatocytes,including miR-27b. And miR-27b can regulate the expression of KSRP. These findings might lay a foundation for further study on the molecular mechanism of fibrosis induced by schistosome infection.
