Objective To investigate the expression changes of nuclear factor-kappa B(NF-kB) and intercellular adhesion molecule-1(ICAM-1)in rats with severe acute pancreatitis(SAP)and the effect of pretreatment of pioglitazone,a specific peroxisome proliferator-activated receptor?(PPAR?),)ligand, on the development of SAP.Methods Fifty-four SD rats were divided into sham operation group(C), SAP group(A)and pioglitazone pretreatment group(Ⅰ).The SAP was induced by retrograde infusion of 5% sodium taurocholate(0.1 ml/100 g)into the biliopancreatic duct.The rats inⅠgroup were intraperi- toneally injected with pioglitazone(2 mg/100 g)two hours before operation.The rats were sacrificed at 3,6 and 12 hrs,the blood,ascites and pancreatic tissues were collected(6 rats once for each group). The expressions of NF-kB and ICAM-1 in pancreatic tissues were measured by immunochemistry,mean- while the serum amylase,the amount of ascitic,pancreatic wet/dry ratio were measured.The pathologi- cal changes of pancreatic tissues were observed by immunochemistry staining with hematoxylin and eosin and the score of the tissues were evaluated.Results Pretreatment with pioglitazone could significantly attenuated the severity of SAP,including reduction of amylase and ascites,and the mass and pathological scores of the pancreatic tissue were decreased after 6 hrs of medication.The expression of ICAM-1 and NF-kB activity were inhibited.Conclusions Above findings demonstrate that pioglitazone can attenuate the severity of SAP by inhibition of ICAM-1 expression and NF-kB activation.The beneficial effects of pioglitazone might be due to its anti-inflammatory activities.The pioglitazone can be used as a new drug in treatment of SAP.

Objective To compare the treatment effect of autologous blister skin grafting with ReCell autologous chromocyte grafting on cicatricial depigmentation caused by deep burn.Methods Thirty-four patients with cicatricial depigmentation caused by deep burn who were admitted into hospital from May 2012 to February 2015 were included in this study.The total 61 depigmentation areas were randomly divided into two groups;32 areas from 18 patients were treated with autologous blister skin grafting,and the other 29 areas from 16 patients were trea-ted with ReCell autologous chromocyte grafting.In the autologous blister skin grafting treated group,epidermis from the depigmentation area was removed by grinding with a BY-II AM type epidermal graft vitiligo treatment equipment.Then the autologous blister skin was harvested with the suction blistering method and grafted onto the wound of depigmentation area.In the ReCell autologous chromocyte grafting treated group,split-thickness skin flap was harvested by electric dermatome.Then the donor skin was processed into chromocyte suspension with the ReCell assay kit and evenly sprayed onto the depigmentation areas.The wound healing time and the pigment recovery 3 months after surgery were observed.Results The wound healing time of autologous blister skin grafting treated group was significantly shorter than that of ReCell autologous chromocyte grafting treated group (P <0.05 ).The effective rate of pigment recovery 3 months after surgery in autologous blister skin grafting treated group was markedly higher than that of ReCell autologous chromocyte grafting treated group(P <0.05 ). Conclusion The autologous epidermal grafting treatment using grinding and suction blistering method is simple and easy to perform,marked-ly effective,with no suture scar and low surgical risk,thus serving as a promising and ideal therapeutic method for burn scar depigmentation.

OBJECTIVETo explore the mechanisms of Qianjing Decoction in the treatment of oligoasthenospermia (OAS).

METHODSWe randomly divided 100 SPF male rats into five groups of equal number: normal, model, Huangjingzanyu, levocarnitine, and Qiangjing. OAS models were established in the animals followed by intragastrical administration of normal saline, ornidazole, Huangjingzanyu Capsules (200 mg per kg body weight per day), levocarnitine (100 mg per kg body weight per day), and Qianjing Decoction (10 g per kg body weight per day), respectively, qd, for 4 successive weeks. Then, we detected the concentration and motility of the epididymal sperm, obtained the contents of superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GSH-Px), lactate dehydrogenase (LDH), α-glucosidase, and fructose in the epididymis, and determined the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and succinate dehydrogenase (SDH) in the epididymal tissue of the rats by real-time PCR.

RESULTSThe concentration and motility of the epididymal sperm in the model, Huangjingzanyu, levocarnitine, and Qianging groups were (35.34 ± 4.22) x 10(6)/ml and (40.04 ± 7.05)%, (48.12 ± 5.56) x 10(6)/ml and (62.46 ± 7.12)%, (47.14 ± 4.87) x 10(6)/ml and (63.23 ± 6.34)%, and (50.25 ± 5.08) x 10(6)/ml and (66.34 ± 7.58)%, respectively, all significantly lower than in the normal group ([53.05 ± 4.55] x 10(6)/ml and [70.20 ± 8.54]%) (P < 0.05), but remarkably higher in the Huangjingzanyu, levocarnitine, and Qiangjing groups than in the model rats (P < 0.05). Compared with the thinned epididymal lumen walls, decreased sperm count, and disorderly and loose arrangement of the lumens in the OAS models, the rats in the Huangjingzanyu, levocarnitine, and Qiangjing groups showed evidently thicker epididymal lumen walls, with the lumens full of sperm cells and arranged regularly and compactly, similar to those of the normal rats. The levels of SOD and GSH-Px were significantly lower but that of MDA markedly higher in the model rats ([84.12 ± 23.25], [10.56 ± 3.02], and [14.04 ± 2.06] nmol/mg) than in the normal group ([110.04 ± 19.56], [17.25 ± 3.56], and [8.87 ± 1.35] nmol/mg) (P < 0.05), while the former two indexes remarkably higher and the latter one significantly lower in the animals treated with Qiangjing Decoction ([120.56 ± 23.68], [16.34 ± 3.12], and [8.45 ± 1.56] nmol/mg), Huangjingzanyu Capsules ([115.34 ± 21.35], [15.23 ± 3.67], and [8.33 ± 1.54] nmol/mg), and levocarnitine ([116.67 ± 22.67], [15.35 ± 3.45], and [8.05 ± 1.78] nmol/mg) than in the models (P < 0.05). The levels of fructose, LDH and α-glucosidase were decreased markedly in the OAS models ([100.22 ± 12.12] mg/[ ml x g], [322 ± 46.13] U/[ ml x g], and [10.48 ± 2.33] U/[ml x g]) as compared with the normal rats ([128.12 ± 13.45] mg/[ml x g], [428 ± 35.12] U/[ml x g], and [15.34 ± 3.12] U/[ ml x g]) (P < 0.05), remarkably higher in the rats treated with Qiangjing ([130.23 ± 13.67] mg/[ml x g] [455 ± 51.50] U/[ml x g], and [18.56 ± 4.67] U/[ml x g]), Huangjingzanyu ([124.16 ± 14.02] mg/[ml x g], [ 419 ± 43.14] U/[ml x g], and [17.64 ± 4.08] U/[ml x g]), and levocarnitine ([123.34 ± 14.02] mg/[ml x g], [430 ± 31.80] U/ [ml x g], and [16.85 ± 5.55] U/[ml x g]) than in the models (P < 0.05). The Nrf2 mRNA expression was significantly reduced in the models as compared with the normal rats (P < 0.05) but remarkably increased in the Huangingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05). The SDH mRNA expression was significantly lower in the model than in the normal rats (P < 0.05) but markedly elevated in the Huangjingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05), remarkably higher in the Qiangjing than in the Huangjingzanyu group (P < 0.05).

CONCLUSIONOrnidazole induces OAS in rats, which is closely associated with excessive oxidation and energy metabolism dysfunction. Qiangjing Decoction can improve and even reverse ornidazole-induced OAS in rats as well as improve the ultrastructure of their testicular and epididymal tissues. Antioxidation and improvement of energy metabolism are probably the action mechanisms of Qiangjing Decoction in the treatment of OAS.

Objective To discuss the expressions and clinical significance of p53 and p33ING1b in human psoriasis and basal cell carcinoma (BCC). Methods Immunohistochemistry EnVision technique was used to detect the expressions of p53 and p33ING1b in samples of 36 psoriasis vulgaris, 28 BCC and 14 normal skins. Results The expression of p53 increased while p33ING1b had a degressive expression in the control group, the psoriasis group and the BCC group. It was found significant statistical difference between the two groups (all P < 0.05). Prominent positive correlation between p53 and p33ING1b were found in both psoriasis group and BCC group (all P<0.05). Conclusions p53 coacts with p33ING1b at local lesions of abnormal proliferative diseases . It′s one of the most prominent mechanisms contributing to deviant cell proliferation.
