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 examine the epidemiology of kidney stone in Pudong New Area ofShanghai and analyze its risk factors. Methods 12 565 residents with the age above 16 years weresurveyed. All subjects needed to answer a questionnaire concerning their sex,age,geographic loca tions,occupation,education status and family history of renal calculi,etc. Ultrasound examinationwas used to diagnose the kidney stone. Results The average prevalence of kidney stone was 3.15%(396/12565),4. 05%(247/6096)in the men and 2.30%(149/6469) in the women,respectively (P<0. 05). The prevalence increased significantly with age of men,whereas the prevalence was highest forwomen aged 50-59. The prevalence between city and rural was not significantly different before age60 (2.58% vs 2. 62%,P>0. 05),whereas the prevalence were significantly different after age 60(6.28% vs 3.36%,P<0.05). The prevalence of subjects with a family history of renal calculi washigher than that without family history (32.02% vs 2.06%,P<0. 01). The prevalence in manage ment staff and vehicle drivers were the highest. Conclusions The prevalence of kidney stone in Pud ong New Area of Shanghai was lower than that in south of China. The relative risk increased in sub jects of aged men,women aged 50 59,with family history of renal calculi,management staff and ve hicle drivers. An understanding of the epidemiology particularly the interactions among different fac tors,may help lead to approach that reduce the risk of stone formation.

OBJECTIVETo investigate the clinical effects of plate and xenogenic bony plate for the treatment of nonunion of femoral shaft fracture after initial fixation with locked intramedullary nailing.

METHODSFrom February 2006 to June 2013, 21 cases with nonunion of femoral shaft fracture after initial fixation with locked intramedullary nailing were treated with femoral plate and contralateral xenogenic bony plate. There were 12 males and 9 females with an average age of 34.8 years old (ranging from 18 to 62 years). The time of nonunion was 9 to 18 months (averaged 12.8 months). The clinical outcomes of the treatment were evaluated by Merchan assessment.

RESULTSAll of the patients were primary healing, and on complications such as infection,fat embolism, internal fixation breaking or rotational deformity, shortening were occurred. All the cases were followed up for 13.2 months (ranging from 8 to 24 months). Nineteen cases were bone healed,the time of union averaged 6.2 months (ranging from 4 to 9 months). Two cases appeared delayed union and gained bony union after 7 to 13 months' observation. According to the criterion of Merchan,the results were excellent in 13 cases, good in 6 cases, poor in 2 cases.

CONCLUSIONTreatment of nonunion of femoral shaft fracture after initial locked intramedullary fixation with plate and xenogenic bony plate has advantages of high curative rate and low complications, good postoperative function recovery, it is a reliable treatment to elevate the stability of fixation and promote the osteogenesis.

BACKGROUNDThe role of tumor-infiltrating lymphocytes (TILs) in the immunopathogenesis of individual cancer is not clear and is a challenge for anti-tumor immunotherapy. This study aimed to investigate the effects of interleukin (IL)-18 and -12 on cytotoxic functions of TILs.

METHODSTILs from postoperative gastric cancer patients were costimulated with IL-18 and IL-12. SGC-7901 tumor cells were pre-incubated with TILs and subcutaneously injected into BALB/C SCID mice. The function of TILs was evaluated by measuring tumor sizes in tumor-bearing mice, T helper (Th)1 (tumor necrosis factor (TNF)-α, interferon (IFN)-γ) and Th2 cytokine levels (IL-10 and IL-4) in serum and cytotoxicity of mouse natural killer (NK) and CD8(+) T cells.

RESULTSIL-18 and IL-12 synergistically inhibited the growth of SGC-7901 cells in vivo and significantly extended the survival rate of SGC-7901-bearing mice (66.7% vs. 13.7%, P < 0.01). Moreover, TILs could promote the secretion of TNF-α and IFN-γ ((130.34 ± 7.65) vs. (210.63 ± 12.31) pg/ml, P < 0.01; (14.23 ± 1.97) vs. (30.52 ± 2.12) pg/ml, P < 0.01), and downregulate IL-10 and IL-4 secretion ((103.72 ± 11.21) vs. (61.36 ± 5.41) pg/ml, P = 0.021; (49.36 ± 4.67) vs. (28.48 ± 3.86) pg/ml, P = 0.024).

CONCLUSIONIL-18 and IL-12 can synergistically enhance cytotoxic functions of TILs from human gastric cancer.
