Objective To study the clinical significance and change law of the serum inflammatory factor in the elder patients with femoral neck fracture during perioperative period. Methods 62 patients with femoral neck fracture were selected as research object,and the serum IL-1,IL-6,IL-10,TNF-α,CRP and BGP of the patients at preoperative day and after the treatment at the first,third,seventh and fourteenth day were detected with ELISA. Results The serum IL-1 ,IL-6,IL-10,TNF-α and CRP went up first and then down,the levels were highest at the third day, and they were compared to the levels at preoperative day( t = 3.34,3.53,3.44,3.69, all P ＜ 0. 05 ), the levels at the fourteenth day returned to normal levels,but the serum BGP showed a rising trend,the level was highest at the fourteenth day, and it was compared to the level at preoperative day( t = 2. 87, P ＜ 0. 05 ). Conclusion The changes of the serum inflammatory factor in the elder patients with femoral neck fracture during periopearative period showed regular pattern, and it was meaningful for understanding the developing and prognosis.

In vivo imaging system (IVIS) is a new and rapidly expanding technology, which has a wide range of applications in life science such as cell tracing. By counting the number of photons emitted from a specimen, IVIS can quantify biological events such as tumor growth. We used B16F10-luc-G5 tumor cells and 20 Babl/C mice injected subcutaneously with B16F10-luc-G5 tumor cells (1x10(6) in 100 muL) to develop a method to quantitatively analyze cells traced by IVIS in vitro and in vivo, respectively. The results showed a strong correlation between the number of tumor cells and the intensity of bioluminescence signal (R (2)=0.99) under different exposure conditions in in vitro assay. The results derived from the in vivo experiments showed that tumor luminescence was observed in all mice by IVIS at all days, and there was significant difference (P<0.01) between every two days from day 3 to day 14. Moreover, tumor dynamic morphology could be monitored by IVIS when it was invisible. There was a strong correlation between tumor volume and bioluminescence signal (R (2)=0.97) by IVIS. In summary, we demonstrated a way to accurately carry out the quantitative analysis of cells using IVIS both in vitro and in vivo. The data indicate that IVIS can be used as an effective and quantitative method for cell tracing both in vitro and in vivo.

Objective To observe the pathologic features on cardiac allograft and to test archived endomyocardial biopsy specimens for antibody-mediated rejection specific marker-C4d deposition and its characteristics by using immunoperoxidase (IP) techniques. Methods From January 2003 to December 2007,10 recipients underwent orthotopic cardiac transplantation and 17 specimens of endomyocardial biopsy were obtained either for a protocol basis (generally at 1 st month,3rd month,1st year and 2nd year post-transplant) and on immediate clinical indications.All specimens of endomyocardial biopsy were collected for histopathological examination and C4d immunohistochemical staining,simultaneously. All pathological diagnoses were done according to 2004 International Society for Heart and Lung Transplantation (ISHLT) recommendation working formulation and AMR Schema,and C4d staining intensity were graded and recorded as 0 to 3 +.Results Except 1 specimen unqualified,all 16 consecutive specimens of endomyocardial biopsy were qualified.There were 4 cases of acute T cell-mediated rejection (all graded 1 ),2 cases of Quilty lesion,and 7 cases of antibody-mediated rejection,who were documented according to ISHLT Schema and C4d deposition.Meanwhile,there were 6 cases showing evidence of antibody-mediated rejection without concurrent acute cellular rejection and only one case concordant with acute T cell-mediated rejection.One case of antibody-mediated rejection died 20 months posttransplantation due to combined transplant coronary artery disease (TCAD). The C4d in the cardiac allograft was deposited in microvasculature diffusively.Conclusion Antibody-mediated rejection is an important clinical entity following orthotopic heart transplantation and is difficult to diagnosis except to perform endomyoeardial biopsy.Immunoperoxidase staining for C4d is a sensitive and specific technique for detecting one marker of antibody-mediated rejection.

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.

Objective To compare the difference of protein and lipid metabolism between patients with inflammatory bowel disease and healthy controls,and to investigate the association of these changes with disease activity and location of the lessions.Methods The retrospective cohort study was carried out.The data of protein and lipid metabolisms collected from 195 patients with ulcerative colitis,76patients with Crohn's disease and 97 healthy controls during 1995 to 2007 were analyzed.Disease activity were evaluated using simple clinieal colitis activity index and simple index of Crohn's disease activity.The erythrocyte sedimentation rate(ESR)and C-reactive protein(CRP)were measured.Results Serum levels of ESR in patients with ulcerative colitis were negatively linear correlated with serum levels of albumin/globulin ratio(β=-0.521,P＜0.01)and positively linear correlated with serum levels of α2globulin(β=0.319,P＜0.01).Serum levels of globulin in patients with Crohn's disease were positively linear correlated with serum levels of ESR(β=0.558,P＜0.01)and CRP(β=0.424,P=0.01).In ulcerative colitis,serum levels of albumin/globulin ratio,albumin and total cholesterol were significantly higher in patients with proctosigmoiditis than those in patients with lesions at other locus(P=0.003,0.005,0.038,respectively).In Crohn's disease,serum level of globulin was significantly higher in patients with lesions only at colon than that in patients with lesions only at small bowel(P=0.029).Conclusions Serum levels of albumin/globulin ratio and α2-globulin can be predictors of inflammatory activity in patients with ulcerative colitis.The increasing serum globulin may predict the progression of disease activity in patients with Crohn's disease.The nutritional deficiency is more critical in patiens with small bowel involvement than those with colon involvement.
