Medical Journal of Chinese People's Liberation Army 2013;38(4):313-315
Objective To analyze the outcomes and postoperative complications of renal transplant recipients of ethnic minorities and Han population in China, and investigate the differences between them. Methods Clinical data from 89 minority patients and 100 Han patients who had received renal transplant of Hans' donators in Organ Transplantation Center of PLA from 1990 to 2012 were retrospectively analyzed. The general data before transplantation, and rate of short-term survival of the graft, incidence of delayed graft function (DGF), acute rejection, and pulmonary infection after transplantation were analyzed and compared. Results No statistical difference was found in the preoperative personal profile between the recipients of minorities and Han nationality. In the recipients of minorities and Han nationality, the 1-year graft survival rate was 89.9% and 92%, the respective incidence of DGF was 28.1% and 27.0%, and the respective incidence of acute rejection was 22.5% and 19.0%, and there was no significant difference between them (P>0.05). The incidence of pulmonary infection was higher in minority recipients (30.3%) than in Han recipients (10.0%, P<0.01), but no significant difference was found between Tibetan, Hui, Manchu and Mongolian recipients in 1-year graft survival rate, incidence of DGF, acute rejection and pulmonary infection (P>0.05). Conclusion The short-term clinical outcome of renal transplant recipients seems to be similar in different Chinese ethnic groups, but the incidence of pulmonary infection is higher in minority recipients, so it is important to strengthen monitoring in early postoperative period.
5. Induction of apoptosis in human renal tubular epithelial HK-2 cells by emodin and mediation of endoplasmic reticulum stress
Chinese Traditional and Herbal Drugs 2013;44(12):1621-1627
Objective: To investigate the induetion of apoptosis in human renal tubular epithelial HK-2 cells by emodin and whether endoplasmic reticulum (ER) stress is involved in its mechanism. Methods: HK-2 cells were cultured and treated with various concentration of emodin at different time points. The cell viability was determined by MTT assay. The gene expression of glucose-regulated protein 78 (GRP78), CCAAT/enhancer-binding protein-homologous protein (CHOP), activating transcription factor 3 (ATF3), and X-box binding protein 1 splicing (XBP1s) was evaluated by quantitative real-time PCR. The protein expression of caspase-3, GRP78, CHOP, and eukaryotic initiation factor 2 alpha (eIF2α) was detected by Western blotting. Results: The viability of HK-2 cells was decreased by emodin in a dose-dependent manner, and the apoptosis of the cells was associated with caspase-3 shear activation. The treatment with emodin in HK-2 cells caused the increase in eIF2α phosphorylation, XBP1 mRNA splicing, the gene expression of GRP78, CHOP, and ATF3, and the protein expression of GRP78 and CHOP. The pretreatment with 4-phenylbutyric acid and salubrinal significantly increased the viability of HK-2 cells, indicating the role of ER stress in emodin-induced apoptosis. Conclusion: Emodin induces the apoptosis in HK-2 cells and ER stress is involved in emodin-induced apoptosis.

The cyclic voltammetric behaviors of sodium selenite on the gold electrode modified by L-cysteine self-assembled monolayer (L-Syc,Au/SAMs) has been investigated in 0.05 mol/L H_2SO_4 solutions with sodium selenite. Sensitive anodic stripping current of selenium (Se) with the peak potential at 0.99 V (vs. SCE) has been observed. In comparison with the electrochemical properties of sodium selenite on the modified electrode with those on the naked gold electrode, it was found that selenite was reduced to selenium by the redox interaction with sulfur on the monolayer and the monolayer catalytically oxidizes Se as the electrode was positively scanned. According to the electrochemical properties of sodium selenite both on the naked and modified gold electrode, the Se deposition mechanism and catalytic mechanism as well as bionic membrane model were proposed for the bio-utilization of selenite through nano scale selenium.

Objective To compare the therapeutic effect between routine shunting and selective shunting in patients with moderate and severe carotid artery stenosis undergoing carotid endarterectomy (CEA). Methods One hundred and ninety-two patients with moderate and severe carotid artery stenosis undergoing CEA were selected, and the patients were divided into control group (routine shunting) and observation group (selective shunting) according to the random digits table method with 96 cases each. The intraoperative carotid artery occlusion time and incidences of stroke event 30 d after operation were recorded. Results In the observation group, the rate of carotid artery shunting was 35.4% (34/96), among which the rate of carotid artery shunting in patients with contralateral severe carotid artery stenosis or occlusion was 8/13, the rate of carotid artery shunting in patients with unilateral carotid stenosis was 31.3% (26/83), and there was statistical difference (χ2 = 13.006, P<0.01). There was no statistical difference in intraoperative carotid artery occlusion time between control group and observation group ( t=2.091, P>0.05). In the observation group, the intraoperative carotid artery occlusion time in patients with carotid artery shunting was significantly shorter than that in patients without carotid artery shunting:(4.36 ± 0.48) min vs. (10.15 ± 0.91) min, and there was statistical difference (t=7.884, P<0.05). There was no statistical difference in the incidence of stroke event 30 d after operation between control group and observation group (χ2 = 1.189, P>0.05). Conclusions The selective shunting during CEA can reduce the incidence of postoperative stroke event in patients with carotid artery stenosis, and especially it can give a good clinical effect in the patients with contralateral severe carotid artery stenosis or occlusion.
