口内斜形弧线下颌骨截骨术改善下面部轮廓

目的为探寻更精细的下面部轮廓整形方法。方法根据术前X线评估结果及与受术者充分讨论,对52例求美者进行口内斜形弧线截骨方法,15例同期进行颧骨整形,26例同时施行了咬肌部分切除,14例同时施行了颊脂垫切除,8例同时进行隆颏手术。结果52例中40例表示非常满意,11例满意,1例截骨稍过度,觉得效果较差。非常满意的受术者表示下面部宽度变窄,不论从正面、侧面都具备了一个优美精致的轮廓线,达到了术前的期望值。结论使用口内斜形弧线截骨方法可使下面部轮廓不管是在正面上还是在侧面上都能得到理想的效果,而且操作较简单、切口隐蔽。     

Contraceptive use and pregnancy before and after introducing lactational amenorrhea (LAM) in a postpartum program

There is good evidence that lactational amenorrhea (LAM) is an effective method of fertility regulation during the first 6 months postpartum, provided no other food is given to the baby and the mother remains amenorrheic. However, although breast-feeding is strongly promoted in many maternity hospitals that also run postpartum family planning progams, LAM is rarely included among the contraceptive options being offered.This paper presents the results of an operational study which compared the prevalence of contraceptive use and the cumulative pregnancy rate at 12-months postpartum among 350 women observed before and 348 women studied after introducing LAM as an alternative contraceptive option offered to women following delivery at the Instituto Materno–Infantil de Pernambuco (IMIP), in Recife, Brazil.The percentage of women not using any contraceptive method was significantly lower (p<0.0001) after the intervention (7.4%) than before (17.7%). This difference remained statistically significant after controlling for age, number of living children, marital status and years of schooling. The proportion pregnant one year postpartum was also significantly lower (p<0.0001) after the introduction of LAM (7.4%) than before (14.3%), but the difference was no longer significant after controlling for the same variables. It is concluded that LAM is a useful addition to family planning postpartum programs.     

Protective films formed on copper by oxygen plasma treatment

Oxidation of copper foils by an inductively coupled oxygen plasma results in the formation of an oxide layer. The protective properties of the film are investigated by electrochemical methods. The corrosion potential depends on the working parameters of the plasma and, in particular, on the treatment time.     

Absence of toll-like receptor 4 (TLR4) signaling in the donor organ reduces ischemia and reperfusion injury in a murine liver transplantation model.

This study analyzes how toll-like receptor 4 (TLR4) signaling in the donor organ affects the ischemia and reperfusion injury (IRI) sequel following liver transplantation. Isogenic orthotopic liver transplantations (OLTs) with rearterialization were performed in groups of wild-type (WT) and TLR4 knockout (KO) mice after donor liver preservation in University of Wisconsin solution at 4 degrees C for 24 hours. Unlike WT OLTs, TLR4-deficient OLTs transplanted to either WT or TLR4 KO recipients suffered significantly less hepatocellular damage, as evidenced by serum alanine aminotransferase levels, and histological Suzuki's grading of liver IRI. Disruption of TLR4 signaling in OLTs decreased local neutrophil sequestration, CD4+ T cell infiltration, interferon (IFN)-gamma-inducible protein 10 (CXCL10) and an intercellular adhesion molecule (ICAM-1), as well as tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-2, and IFN-gamma, yet increased IL-4 and IL-10 expression. The well-functioning OLTs from TLR4 KO donors revealed attenuated activity of capase-3, and enhanced heme oygenase-1 (HO-1) expression, along with decreased levels of apoptotic endothelial cells/hepatocytes, as compared with WT OLTs with intact TLR4 signaling. Thus, the functional sentinel TLR4 complex in the donor organ plays a key role in the mechanism of hepatic IRI after OLT. Disruption of TLR4 pathway downregulated the early proinflammatory responses and ameliorated hepatic IRI. These results provide the rationale to locally modify innate TLR4 signaling in the donor organ to more efficiently control the adaptive posttransplantation IRI-dependent responses.     

Gene therapy in liver ischemia and reperfusion injury

Ischemia and reperfusion injury (IRI) is a prime antigen-independent inflammatory factor in the dysfunction of liver transplants. Despite improved allograft preservation and surgical techniques, IRI can still cause up to 10% of early orthotopic liver transplant failure, and can lead to a higher incidence of both acute and chronic graft rejection. Recent advances in gene transfer have resulted in a reduction or inhibition of liver IRI in several experimental models. This review summarizes the development of existing and potential approaches to human gene therapy. These studies aimed at ameliorating I/R injury are focused on the cytoprotective effects in transplant recipients by induction of anti-apoptotic or protective genes, immunoregulation of cytokines or blockade of signaling transduction pathway in graft cells. Although this review focuses on the application of viral mediated gene therapy, new non-viral gene transfer techniques, such as RNA interference (RNAi) application, are discussed. Future advances in gene therapy technology should result in fewer side effects, and thus more acceptable for clinical application, and more successful for organ transplantation.     

原发性胃黏膜相关淋巴组织淋巴瘤29例临床分析

目的：分析胃黏膜相关淋巴组织（MALT）淋巴瘤临床、胃镜、病理特征,提高早期检出率。方法：回顾性分析经胃镜活检及手术后病理证实胃MALT淋巴瘤29例患者的临床资料。结果：29例患者临床表现多样,以上腹痛多见,幽门螺杆菌（HP）感染率高达93%,胃镜下病灶好发于胃窦、胃体,但胃镜下活检阳性率较低,仅占48%。结论：胃MALT淋巴瘤临床表现无特异性,胃镜下表现多样,提高临床和胃镜医师对本病的认识以及提高胃镜下活检阳性率活检标本加做免疫组织化学染色是早期诊断胃MALT淋巴瘤的关键。
