Apolipoprotein C1 promotes prostate cancer cell proliferation in vitro.

Here, we aimed to investigate the carcinogenic effects of apolipoprotein C1 (APOC1) in prostate cancer (PCa). APOC1 expression was evaluated in PCa and normal prostate specimens, and lentivirus-mediated RNA interference was used to knockdown APOC1 in DU145 cells. The effects of APOC1 silencing on cell proliferation, cell cycle arrest, and apoptosis were assessed.

Characterization of a water-soluble polysaccharide from Boletus edulis and its antitumor and immunomodulatory activities on renal cancer in mice.

A polysaccharide (BEP, Mw=113,432Da) was purified from Boletus edulis, which had a backbone consisting of (1→6)-linked-α-d-glucopyranosyl, (1→2,6)-linked-α-d-galactopyranosyl, (1→6)-linked-α-d-galactopyranosyl, and (1→3)-linked-α-d-rhamnopyranosyl residues, which were branched at O-2 position of (1→2,6)-linked-α-d-galactopyranosyl residue with a single terminal (1→)-linked-α-l-arabinofuranosyl residue. After 32 days' BEP administration to Renca tumor bearing mice, the tumor mass of Renca transplanted in mice was significantly repressed. Furthermore, BEP could significantly increase the spleen and thymus indices, stimulate splenocytes proliferation, augment NK cell and CTL activities in spleen, and promote the secretion of the cytokines IL-2 and TNF-α in Renca tumor bearing mice.

[Effect of CYP3A4*18B, CYP3A5*3 gene polymorphism on dosage and concentration of tacrolimus in renal transplant patients].

The effect of CYP3A4*18B and CYP3A5*3 on concentration/dosage x body surface area ratios (C/D'), adverse effects and acute rejection of tacrolimus in renal transplant patients were investigated. The CYP3A4*18B genotypes of 227 renal transplant patients were determined by PCR-RFLP method. The differences of C/D' ratios, adverse reactions and acute rejection were compared among all of the genotype groups treated with tacrolimus.

Alemtuzumab induction therapy in highly sensitized kidney transplant recipients.

Background: Immunosuppression for immunologically high-risk kidney transplant patients usually involves antithymocyte globulin induction with triple drug maintenance therapy. Alemtuzumab, a humanized anti-CD52 antibody, was expected to be a promising induction therapy agent for kidney transplantation. However, currently no consensus is available about its efficacy and safety.

[Effects of delta1 gene transfection on biological behaviors of rat dendritic cells].

Aim: To explore the effects of Delta1 gene on rat bone marrow-derived dendritic cells (DCs).

Methods: pcDNA3.1/delta1 plasmid was transfected into Rat DCs with lipofectamine gene transfection method.

Pre-transplant soluble CD30 level as a predictor of not only acute rejection and graft loss but pneumonia in renal transplant recipients.

Pre-transplant sera of 586 renal graft recipients were tested to investigate whether soluble CD30 (sCD30) is a useful predictor of some severe clinical episodes post-transplant. Correlation analysis showed sCD30 level was significantly correlated with acute rejection (AR) (r=0.242, P<0.

Factors influencing second renal allograft survival: a single center experience in China.

Second renal transplants are historically associated with a poor prognosis. The aim of the present study was to assess long-term survival of second renal grafts from deceased donors performed at our center and to analyze risk factors associated with long-term graft outcome. Sixty-five second renal grafts were enrolled into this study, and compared to primary ones performed during the same period.

The long-term outcomes of pediatric kidney transplantation: a single-centre experience in China.

To explore the long-term outcomes of paediatric kidney transplantation and the effects of renal allograft on growth, education, employment, marriage and procreation. Twenty-seven children with ESRD received the renal allograft from 1985 to 2001. The patient and kidney survival rate, renal function, growth and employment, etc.

Comparison of single bolus ATG and Basiliximab as induction therapy in presensitized renal allograft recipients receiving tacrolimus-based immunosuppressive regimen.

Presensitized renal allograft recipients require special management to improve their outcome, and there is no consensus on the optimal immunosuppressive strategy. We retrospectively analyzed clinical data of 82 patients, who were PRA positive pre-transplant (above 10%) and received single bolus ATG and basiliximab as induction therapy, and assessed safety and efficacy of two kinds of induction therapies. Patients of ATG group (n=40) received single bolus ATG (Fresenius, 9 mg/kg preoperatively) and those of basiliximab group (n=42) were given two doses of basiliximab (Simulect, Novartis, 20 mg) on days 0 and 4 post-transplant.

Pre- and post-transplant monitoring of soluble CD30 levels as predictor of acute renal allograft rejection.

Identification of renal graft candidates at high risk of impending acute rejection (AR) and graft loss may be helpful for patient-tailored immunosuppressive regimens and renal graft survival. To investigate the feasibility with soluble CD30 (sCD30) as predictor of AR, sCD30 levels of 70 patients were detected on day 0 pre-transplant and day 1, 3, 5, 7, 10, 14, 21, and 30 post-transplant. AR episodes in 6 months were recorded and then patients were divided into Group AR (n=11) and Group UC (n=59).
