OBJECTIVETo observe the change of Th immunological gene in renal transplant recipients after the treatment of cyclosporine (CsA) and tacrolimus (FK506).

METHODSThe peripheral blood lymphacytes just before and 24 hours after CsA and FK506 treatment were isolated. The total RNA of them were reverse-transcripted and examined by real-time quantity PCR array. The results were analyzed by bioinformatic methods.

RESULTSThe TLR4, CEBPB, IL4R, IL1R1,IL18R1,and IL1R2 genes were remarkably upregulated, whereas IL-2, CCL5, CD27, CCR5, CCR4, CD4, RPL13A, TGFB3, CD86, CCR3, STAT1, NFATC2IP, IL23A, IL15, IRF4, and TFCP2 were downregulated 24 hours after CsA treatment. The IL18, IL7, PTPRC, TNFSF4, SPP1, GFI1, TLR4, IL13RA1, TNF, INHBA, LAG3, IL13, IL1R1, SOCS5, IL10, YY1, TBX21, FASLG, IL18R1, and IL1R2 genes were remarkably upregulated, whereas IL-2, IL-3, IL-4, IL-6,CCR5, CD4, CD27, CD40LG, IL15, CCR3, CD86, CCR4, and IRF4 were obviously downregulated 24 hours after FK506 treatment.

CONCLUSIONCsA and FK506 exert their therapeutic effectiveness by regulating the expressions of a series of target genes.

Renal cell carcinoma (RCC) in a solitary kidney presents a unique clinical challenge to urological surgeons. Partial nephrectomy (PN) or nephron-sparing surgery in this condition provides good oncological and renal functional outcomes with an acceptable complication rate. Long-term renal function remains stable in most patients with solitary kidneys after a reduction of more than 50% in renal mass.PN is a surgical procedure reserved for patients with a tumor in a solitary kidney, bilateral renal tumors, or renal function impairment. The challenge of preserving renal parenchyma is significantly complicated with the discovery of multiple masses in a solitary kidney because any subsequent complications may result in a significant decline in quality of life. Particularly in the case of postoperative renal failure, dialysis becomes necessary.

OBJECTIVETo retrospectively investigate the distribution in kidney transplantation for fifteen years in Peking Union Medical College Hospital.

METHODSWe conducted a descriptive research counting up the number of patients who received kidney transplantation each year in our hospital during 1995 and 2010.

RESULTSThe first kidney transplantation in our hospital occurred in the 1960s. The number of kidney transplantation increased until reaching a maximum of 47 grafts in 2001; since then the number fell.

CONCLUSIONSWith the decreased number of kidney transplantation, we have realized the shortage of transplantable organs is very serious. The continuing transplant shortage requires major efforts to expand the donor pool. Donation after cardiac death offers the potential to enlarge the donor pool, but we need to strictly control the criteria for potential donors.

OBJECTIVETo study the mental health status of infertility patients with varicocele and its relationship with infertility.

METHODSUsing Hospital Anxiety and Depression scale (HAD), we assessed the psychological status of 110 infertility patients with varicocele, identified the risk factors of anxiety and depression in these patients, and analyzed the correlation among psychological and other relevant factors. Meanwhile, we recruited 61 age-matched normal fertile men as controls for comparative analysis. We also conducted logistic regression analysis on the mental health status of the 106 infertility patients with varicocele.

RESULTSThe prevalence rates of anxiety were 61.32% and 13.79%, while those of depression 37.73% and 6.90% in the infertile patients and normal fertile controls, respectively, significantly higher in the former than in the latter (P < 0.05). Logistic regression analysis showed that the main risk factors of anxiety and depression of the infertile patients were the number of times they sought medical care and the severity of their testis disorders.

CONCLUSIONInfertility patients with varicocele have psychological disorders, which are particularly associated with the frequency of the patients' clinic visit and the severity of their testis disorders.

OBJECTIVETo improve the recognition of Fechtner syndrome.

METHODSThe clinical and laboratory data and family survey of a patient with Fechtner's syndrom was reported.

RESULTS AND CONCLUSIONGiant platelets, thrombocytopenia and characteristic granulocyte inclusion bodies (Döhle-like bodies) were found in both peripheral blood and bone marrow smears of the patient. Clinically the patient had renal damage, nervous deafness, and vitreous lesions. There was a family genetic tendency on family survey the diagnosis of Fechtner syndrome is established.

OBJECTIVETo investigate the possible mechanism of L-arginine supplementation on the angiogenesis of burn wounds in diabetic rats.

METHODSOne hundred male Sprague-Dawley (SD) rats were used in the study and were randomly divided into A (scalding control, n = 25), B (scalding of the rats with diabetes, n = 25), C (L-glycine control, n = 25) and D (L-arginine supplementation, n = 25) groups. Diabetes was produced by intra-peritoneal injection of streptozotocin (STZ) in B, C and D groups. The rats in C and D groups were gavaged with L-glycine and L-arginine in dose of 200 mg.kg(-1).d(-1), respectively. The glucose content of the back skin tissue was determined for five rats in each group eight weeks after STZ administration. Deep partial thickness scalding of 20% TBSA was engendered on the back in the other 80 rats. The wound area, wound healing rate, and microvascular density with CD34 immunohistochemistry staining were determined on 3rd, 7th, 14th, and 21st post scalding days (PSDs), In addition, the amount of nitric oxide (NO) released from the wound tissue and the tissue contents of vascular endothelial growth factor (VEGF) and transforming growth factor beta1 (TGF-beta1) from wound were determined at the above time points.

RESULTSCompared to those in group B, the wound healing rate in group D increased significantly since the 7th PSD [(44.10 +/- 3.50)%, P < 0.05], and the wound MVD value was increased significantly at all postburn time points. Furthermore, the levels of VEGF, NO and TGF-beta1 in the wound tissue was also increased significantly, while the glucose content in the cutaneous tissue was decreased to (1.380 +/- 0.120) mg/g.

CONCLUSIONL-arginine supplementation could be beneficial to the angiogenesis in the burn wound of the rats with diabetes, as well as to wound healing by increasing the synthesis and the release of VEGF, NO and TGF-beta1 from burn wound and by decreasing the glucose content in the cutaneous tissue of diabetic rats.

The expression levels of programmed cell death 5 (PDCD5) are down-regulated in many malignancies. SG611-pdcd5, a recombinant conditionally replicative adenovirus carrying pdcd5 gene expression cassette, can evidently kill the leukemic cells and protect selectively the normal cells. The purpose of this study was to investigate the synergistic killing effect of SG611-pdcd5 and low-dose etoposide (VP-16) on K562 cells. K562 cells were treated with different concentrations of VP-16 or different multiplicities of infection (MOI) of SG611-pdcd5. After 48 hours of incubation the cell viability was determined by using MTT assay. The results showed that the cell viability of SG611-pdcd5 (MOI = 40) plus VP-16 (0.5 µg/ml) group significantly decreased as compared with single SG611-pdcd5 (MOI = 40) treatment group or single VP-16(0.5 µg/ml) treatment group (42.00 ± 5.75% vs 59.45 ± 4.12%; 42.00 ± 5.75% vs 82.91 ± 3.41%, respectively, both p < 0.05). The synergistic killing effect of SG611-pdcd5 plus VP-16 was higher than that of PDCD5 protein plus VP-16 or that of non-replicating adenovirus carrying pdcd5 (Ad-pdcd5) plus VP-16 (both p < 0.05). The cell viability of VP-16 (4.0 µg/ml) plus SG611-pdcd5 (MOI = 40) group, VP-16 (4.0 µg/ml) plus proPDCD5 (40 µg/ml) group and VP-16 (4.0 µg/ml) plus Ad-pdcd5 (MOI = 80) group was 37.09 ± 1.89%, 52.36 ± 1.64% and 73.64 ± 4.33%, respectively. It is concluded that SG611-pdcd5 can promote K562 cell death induced by low-dose VP-16. The combination of SG611-pdcd5 and VP-16 can enhance the killing effect on leukemic cells.
