Pancreatic Panniculitis Associated with Allograft Pancreatitis and Rejection in a Simultaneous Pancreas–Kidney Transplant Recipient

Pancreatic panniculitis is an uncommon condition that can occur in association with pancreatic disease. We present a case of pancreatic panniculitis in a female pancreas-kidney transplant recipient 5 months post-transplant. The patient was on standard immunosuppressive medications and had acute rejection of her renal allograft. The diagnosis of allograft pancreatitis and rejection presenting with pancreatic panniculitis was supported clinically, histopathologically and by laboratory and imaging data. This is the fourth case of pancreatic panniculitis occurring in a transplant recipient and the first in a simultaneous pancreas-kidney transplant recipient. It is also the first case associated with allograft rejection. Clinicians should be aware that pancreatic panniculitis may be a manifestation of underlying allograft pancreatic disease.     

Ex Vivo Application of Carbon Monoxide in University of Wisconsin Solution to Prevent Intestinal Cold Ischemia/Reperfusion Injury

Carbon monoxide (CO), a byproduct of heme catalysis, was shown to have potent cytoprotective and anti-inflammatory effects. In vivo recipient CO inhalation at low concentrations prevented ischemia/reperfusion (I/R) injury associated with small intestinal transplantation (SITx). This study examined whether ex vivo delivery of CO in University of Wisconsin (UW) solution could ameliorate intestinal I/R injury. Orthotopic syngenic SITx was performed in Lewis rats after 6 h cold preservation in control UW or UW that was bubbled with CO gas (0.1-5%) (CO-UW). Recipient survival with intestinal grafts preserved in 5%, but not 0.1%, CO-UW improved to 86.7% (13/15) from 53% (9/17) with control UW. At 3 h after SITx, grafts stored in 5% CO-UW showed improved intestinal barrier function, less mucosal denudation and reduced inflammatory mediator upregulation compared to those in control UW. Preservation in CO-UW associated with reduced vascular resistance (end preservation), increased graft cyclic guanosine monophosphate levels (1 h), and improved graft blood flow (1 h). Protective effects of CO-UW were reversed by ODQ, an inhibitor of soluble guanylyl cyclase. In vitro culture experiment also showed better preservation of vascular endothelial cells with CO-UW. The study suggests that ex vivo CO delivery into UW solution would be a simple and innovative therapeutic strategy to prevent transplant-induced I/R injury.

邹城市预防艾滋病健康教育效果评价

目的评价预防艾滋病健康教育与行为干预效果。方法采用问卷方式对社区居民进行预防艾滋病信息的可及性及知信行的调查。结果社区居民艾滋病知晓率为97.41%,熟悉艾滋病传播途径的87.78%,62.78%的认为艾滋病病人或感染者和正常人享有一样的入学/就业权,38.70%的人愿意与感染艾滋病的同事继续共事,60.19%的人愿意与感染艾滋病的家人继续共同生活,最近3次性行为100%使用安全套者为26.48%,82.04%的人有医疗用血安全意识,64.81%的人有医疗器械安全意识。最想获取艾滋病预防措施、传播途径、病理知识、症状表现、治疗方法、检测途径及检测方法、疫情信息,新闻、电视公益广告、专题报道、反映艾滋病病人生活的电影或电视剧、科普材料、大型公益演出人们最喜欢。结论政府重视,多部门合作,组织机构健全,宣传教育广泛,干预措施到位,成效显著。     

用Lyman NTCP模型分析原发性肝癌三维适形放疗引起的放射性肝病

目的建立原发性肝癌三维大分割适形放疗Lyman NTCP模型的参数和探讨放射性肝病的影响因素。方法109例患者进行大分割三维适形放疗,其中93例患者肝硬化Child-Pugh分级A级,16例为B级。患者每星期治疗3次,每次间隔48h,(4．8±0．5)Gy/次,平均剂量(53．5±5．5)Gy。用最大拟然比方法分别得到Child-A和Child-B患者Lyman模型中的NTCP参数。结果共有17例发生放射性肝病,发生在Child-A组8例,Child-B组9例。多因数分析表明,肝硬化分级程度是与放射性肝病相关的独立因素(P=0．000)。所有患者的NTCP参数为n=1．1,m=0．35,TD_(50) (1)=38．5Gy；Child-A级为n=1．1,m=0．28,TD_(50)(1)=40．5Gy；Child-B级为n=0．7,m=0．43,TD_(50)(1)=23Gy。结论肝硬化分级是预测放射性肝病发生的危险因子。Child-B患者进行适形放疗易引起放射性肝病。     

An experimentally supported, mathematical explanation of the gas chromatographic elution behaviour of the long-chain carbon members of the homologous series

By substituting the saturated vapour phase tension of the pure normal hydrocarbons described by the Clausius-Clapeyron law into the accepted expression of the specific retention volume (V_g,T), a theoretically coherent and relatively simple mathematical evidence of the elution behaviour of the homologous members has been deduced. It gives exponential retention time dependence on carbon number for isothermal, and nearly equidistant (i.e., approximately linear retention-time dependence on carbon number) elution for linear temperature programmed gas chromatographic runs. The final equations are in close correlation with the experimental results. Special emphasis is placed on the fact that a good approximation—not strict physical laws—have been found.

腹腔脏器损伤210例诊治分析

目的:探讨腹腔脏器损伤的诊治方法。方法：回顾性分析15年间收治的210例腹腔脏器损伤的临床资料。结果：腹腔穿刺阳性率（88.6%）。术前诊断基本准确125例（59.5%）。210例均行手术治疗，治愈190例（90.5%），死亡20例（9.5%）。结论：腹腔多脏器损伤较为常见。腹腔穿刺是可靠的诊断手段，对有剖腹探查指征的病例应积极手术，探查时既要系统全面，防止遗漏，又要避免重复多余的探查。     

广龙昊膏药对大鼠腰椎间盘突出模型细胞因子IL-1、NO及组织胺的影响

为探讨IL-1、NO及组织胺在腰椎间盘突出中的作用及广龙昊膏药的治疗效果，将60只大鼠造模并随机分为正常组（A组）、造模组（B组）、广龙昊膏药组（C组）和奇正止痛膏组（D组），观察其神经根周围局部组织中IL-1、NO及组织胺的含量。结果显示，B组中的IL-1、NO及组织胺较A组显著升高（P〈0．01）。C组、D组较B组明显下降（P〈0．01）。表明大鼠腰椎间盘突出模型中细胞因子IL-1、NO及组织胺明显增加可能是腰椎间盘突出中的潜在始动或促进因素，而C组能显著降低神经根局部中IL-1、NO及组织胺的含量，说明广龙昊膏药作用部分是通过抑制炎性细胞因子的活性实现的。
