同种异体复合组织移植(CTA)是一门新兴的用于治疗功能性组织或肢体缺损的移植学科,由于绝大多数CTA移植物为带血管的移植物,因此也称为带血管的复合组织移植(VCA).CTA/VCA的移植物包含同种异体的皮肤、皮下组织、骨骼、肌肉、神经和血管等两种或多种组织结构成分.由于大多数CTA/VCA移植物中带有皮肤组织,而皮肤组织是抗原性最强的免疫成分,移植术后的急性排斥反应是导致CTA/VCA移植失败及其移植物失功的首要障碍,因此CTA/VCA移植物中的皮肤排斥反应的组织病理学特征成为首要的关注点.本文就CTA/VCA的排斥反应等病理学特征、2007年Banff诊断标准及其研究进展予以综述,以期为CTA/VCA的排斥反应及其他并发症的诊断及治疗提供参考.
目的:讨论复发性卵巢性索间质肿瘤(OSCST)患者的临床特点及预后相关因素.方法:2012年6月至2021年12月期间武汉大学中南医院共收治OSCST患者127例,对其中随访资料完整的12例复发性OSCST患者进行回顾性研究.结果:12例患者首次复发距初次治疗结束的中位无疾病进展期(PFS)为67.5(6~120)月,除2例仅复发一次外,其余10例患者均经历了 2~6次不等的复发过程,总共有33次复发,多次复发的中位PFS为24(1~110)月,最终6例患者死亡,6例患者存活.通过Kaplan-Meier生存分析结果显示复发治疗后的治疗方式(P=0.001)、术后残余瘤(P=0.012)、复发治疗后可测量病灶(P=0.003)与肿瘤复发密切相关.COX多因素分析复发治疗后治疗方式、可测量病灶大小是复发患者的不良预后因素.结论:复发性OSCST患者需根据复发转移部位、残余肿瘤大小等病情严重程度不同选择适当的联合治疗方案,通过尽可能消灭复发转移病灶来延长患者PFS、缓解病情.
With the maturity of organ transplantation technology, the long-term survival of solid organ grafts has gradually become the primary task after transplantation. The main cause of graft function loss after solid organ transplantation is chronic graft damage. However, its potential mechanism is not clear. Graft pathological biopsy is the gold standard for the diagnosis of graft function, but the routine evaluation of graft function is hindered by the invasiveness of biopsy puncture and the limitation of sampling. Therefore, functional monitoring of micro injury non-invasive samples (such as peripheral blood or urine) is more conducive to the management of grafts after solid organ transplantation. This paper will systematically review the literature on biomarkers of long-term graft survival in solid organ transplantation.
Objective:To investigate the epidemic trend and risk change of acquired immunodeficiency syndrome (AIDS) complicated with malignant tumors after combination antiretroviral therapy (cART).Methods:The types of malignant tumors in patients with AIDS at different stages of cART were analyzed among anti-human immunodeficiency virus (HIV)-positive population in Hubei Province screened in National AIDS/HIV prevention and control information system from 1st January, 2004 to 31st December, 2018. The standardized incidence ratios(SIR) of malignant tumors in AIDS patients was analyzed based on the incidence of malignant tumors in the general population in Hubei Province or China in 2013. The changes in risks for development of malignant tumors in AIDS patients at different cART stages from 2004 to 2013 and 2014 to 2018 were compared.Chi-square test was used for statistical analysis.Results:Three hundred and twenty-three out of 22 994 AIDS patients were diagnosed with malignant tumors. Non-Hodgkin lymphoma(NHL) and cervical cancer were most common types in acquired immunodeficiency syndrome-defining cancers (ADC), while liver cancers and lung cancers were the most common types in non-acquired immunodeficiency syndrome-defining cancers (NADC). The overall risk of malignancy in AIDS patients was similar to that in the general population (SIR=1.06, χ2=0.62, P=0.426). However, the risks of Kaposi sarcoma, NHL, Hodgkin lymphoma, cervical cancer, and head and face cancers (excepting nasopharyngeal cancer) in AIDS patients were significantly higher than those in the general population (SIR=834.09, 9.65, 13.33, 5.22 and 2.94, respectively, χ2=11 747.27, 625.54, 56.65, 184.21 and 13.66, respectively, all P<0.01). The risks of lung cancer, colorectal anal cancer, stomach cancer and breast cancer in AIDS patients were significantly lower than those in the general population (SIR=0.33, 0.36, 0.43 and 0.45, respectively, χ2=33.43, 12.84, 9.01 and 7.21, respectively, all P<0.05). The SIR of cervical cancer, liver cancer and colorectal anal cancer from 2014 to 2018 were 4.06, 0.43 and 0.10, respectively, which were significantly lower than those from 2004 to 2013 (7.42, 1.96 and 0.84, respectively). The differences were all statistically significant ( χ2=5.39, 19.52 and 10.86, respectively, all P<0.05). Conclusions:At present, there are no significant differences of the incidences of malignant tumors between AIDS patients and general population, but the tumor types are different. The most common malignant tumors in this region are NHL and cervical cancer, which should be noted that HIV screening among patients with such tumors is conducive to comprehensive treatment to improve the efficacy.

The data of patients with HIV/AIDS from Hubei Province during 2004 to 2018 were obtained from the National AIDS Comprehensive Prevention and Control Information System. A total of 22 980 HIV-positive or AIDS patients were followed up for 113 164 person-years and 323 malignant tumors were diagnosed. Non-Hodgkin′s lymphoma (NHL), cervical cancer, liver cancer, lung cancer, and Kaposi sarcoma (KS) accounted for 70.0% (226/323) of all malignant tumors in this population. The average crude incidence and mortality of malignant tumors in HIV-infected patients were 285.43/100 000(269.11/100 000 in males and 325.87/100 000 in females), and 169.67/100 000(184.78/100 000 in males and 132.19/100 000 in females), respectively. The result indicates that the overall cancer incidence and mortality in HIV/AIDS population under widely implementation of combination anti-retroviral therapy (cART) are similar to those in the general population of the region. But the incidence and mortality of AIDS-related tumors such as KS, NHL, HD and cervical cancer are higher than those in general population, and attention should be given to screening of these malignancies in HIV/AIDS population.
More and more studies have been focusing on marginal donor livers, such as steatotic liver grafts, to alleviate donor shortage and reduce mortality from waiting lists. Poor tolerance of streatotic liver grafts often leads to primary graft nonfunction, early dysfunction, and postoperative vascular and biliary complications. Some studies have shown that moderate and severe macrosteatosis livers can be used for transplantation with rigorous selection of recipients. In this paper, techniques such as venous systemic oxygenated persufflation, hypothermic oxygenated perfusion, subnormothermic machine perfusion, normothermic machine perfusion, improved liver quality, and steatotic liver grafts transplantation were discussed.
当机体生理负荷加重时,肝脏可以额外动员的潜在能力,以及各种致病因子造成肝脏损伤后自我修复且再生的能力,统称为肝脏储备功能[1].目前临床上评估肝脏储备功能的方法有很多种,主要分为肝功能静态检测及肝功能动态检测.肝功能静态检测包括临床上使用最普遍的肝脏血清生化检查,以及肝脏影像学评估和肝功能评分系统.而肝功能动态检测最常用的方法是吲哚菁绿(indocyanine green,ICG)清除试验[2].ICG清除试验主要应用于评估肝脏肿瘤的切除部位及大小,而在肝移植领域中相关报道较少[3].本文就ICG清除试验在肝移植患者中的应用进行综述.

Background Ante-situm resection and auto-transplantation (ante-situm for short) provides a more aggressive approach to conventionally unresectable hepatocellular carcinoma (HCC). We described the long-term outcomes of patients with HCCs who underwent this technique. Material/Methods Between October 2005 and December 2016, we performed 23 ante-situm liver resections. We evaluated postoperative complications, 90-day mortality, recurrence, and long-term survival rates, and reviewed the literature on this topic. Results Five types of complications associated with six patients were observed.: 1) primary nonfunctioning liver, thus receiving a liver transplantation; 2) initial poor liver function with recovery two weeks after treatment; 3) diagnoses of portal vein tumor thrombosis, biliary fistula, and small-for-size syndrome, respectively. The median follow-up was 3.6 years; 12 out of 23 patients were alive at the end of the study. One patient who had hepatic recurrence was lost to follow-up after three months. One patient died of multiple organ dysfunction syndrome after the operation, nine patients died due to hepatic recurrence and/or extrahepatic metastasis of HCC. The one-year, three-year, five-year, and 10-year survival rates were 65.2%, 56.5%, 50.9%, and 20.3%, respectively. The one-year, three-year, five-year, and 10-year recurrence rates were 60.9%, 50.7%, 50.7%, and 50.7%, respectively. The chi-square test revealed the patients with recurrence after ante-situm technique were more likely to have poor prognosis (mortality of patients with recurrence versus no-recurrence: 88.9% versus 14.3%, p<0.05) and a strong association was evidenced by Cramer’s V statistic (Cramer’s V=0.734). Conclusions Ante-situm procedure showed benefits in select patients with HCCs who had contraindications for conventional resection operations. In our case series, the ante-situm technique resulted in lower mortality compared to other ex-vivo hepatic resection techniques reported in the literature and similar long-term efficacy compared to cases of HCCs suitable for conventional resections. HCCs recurrence was a major risk factor associated with the survival rate of ante-situm technique.
