神经干细胞与原浆型星形胶质细胞联合移植对大鼠损伤脊髓轴浆运输功能的修复作用

目的：观察神经干细胞（NSC）与原浆型星形胶质细胞（PAS）联合移植对大鼠损伤脊髓轴浆运输功能的修复作用。方法：40只Wistar大鼠，制成L1～L2左侧脊髓半切空洞损伤模型，随机分为损伤组（A组），损伤后移植PAS组（B组）、移植NSC组（C组）、NSC和PAS按2：1比例联合移植组（D组），每组10只。4周及8周后行损伤部位神经丝-200（NF-200）染色观察NSC在体内的分化情况，腓肠肌胆碱酯酶染色观察运动终板的反应和核黄逆行示踪观察轴浆运输的恢复情况。结果：（1）4周时D组和C组移植部位可见少量NF-200阳性标记的神经元．8周时数量明显增多，D组多于C组；4周及8周时A、B组均未见到明显阳性标记的神经元。（2）4周时．A、B组胆碱酯酶染色示运动终板均出现退变，终板染色变浅；8周时A组终板明显退变，出现大片染色空白区，甚至终板消失，只剩下模糊的轮廓；B组终板退变程度轻于A组，着色淡，轮廓欠清晰，周边呈浅棕红色淡染，但未出现大片染色空白区；C、D组4周时终板边缘发生皱缩，呈颗粒样改变，无明显染色缺失；8周时C组较4周时变化不明显，D组受损终板皱缩明显好转，颗粒样改变消失。（3）4周时，B、C、D组核黄染色的神经元散在位于脊髓的前、后、侧角，其中D组阳性标记的神经元的数量及荧光强度大于B、C组，C组又稍强于B；8周时B、C、D组阳性神经元数量均增多．神经元的数量及荧光强度仍是D组〉C组〉B组；A组4周及8周时均未见到明显阳性染色的神经元。结论：联合移植NSC和PAS（2：1）能更好地修复损伤脊髓的轴浆运输功能并能较好地防治其后肢肌肉运动终板的溃变。

HIV感染者脏腑虚损与NK、NKT细胞功能研究

目的：通过对人免疫缺陷病毒(HIV)感染者脾虚与肾虚患者自然杀伤(NK)细胞、自然杀伤T(NKT)细胞功能的研究,分析不同脏腑虚损状态下NK细胞、NKT细胞功能的差异。方法：选取HIV感染者92例,根据中医证候量表分为脾虚组和肾虚组,对两组NK细胞、NKT细胞功能进行检测。结果：肾虚组患者干扰素-γ(INF-γ)表达降低,但两组间CD₃^-CD₅₆⁺、CD₃⁺CD₅₆⁺、CD_107a、CD₄⁺T淋巴细胞表达均无差异。结论：脾虚与肾虚患者NK细胞数量及功能、NKT细胞数量均无差异,而肾虚患者NKT细胞功能较脾虚组降低。     

228例肺癌在纤支镜下的形态特征分析

目的：了解肺癌在纤支镜下的形态特征。方法：采用纤维支气管镜、病理学等方法对228例患者进行了观察。结果：经纤维支气管镜确诊支气管肺癌228例,占同期纤支镜检查的38.1%。其中143例（62.7%)可见肿瘤直接征象,即新生肿物;75例（32.9%)可见肿瘤的间接征象,在可见肿瘤直接和间接征象的218例中鳞癌147例（67.4%),腺癌32例（14.7%),小细胞癌14例（6.4%),大细胞癌2例（0.9%),肺泡癌4例（1.8%)。此外还有细胞类型不明确者19例（8.7%)。结论：（1）肺腺癌患者男性仍稍多于女性;（2）肺癌是纤维支气管镜检查的重要适应征。

肾移植术后感染新型冠状病毒1例

The novel coronavirus is a newly discovered pathogen in late December 2019, and its source is currently unknown, which can lead to asymptomatic infection, new coronavirus pneumonia or serious complications, such as acute respiratory failure. Corona virus disease 2019 (COVID-19) is a new type of respiratory disease that is currently spreading all over the world and caused by this coronavirus. Its common symptoms are highly similar to those of other viruses, such as fever, cough and dyspnea. There is currently no vaccine or treatment for COVID-19. Everyone is susceptible to infection with this disease, and owing to the long-term use of immunosuppressants, the immunity of kidney transplant recipients is suppressed, and it is more likely to be infected with the disease. At present, its impact on kidney transplant recipients is unclear. This article reports the clinical features and therapeutic course of novel coronavirus infection in a patient after renal transplantation. A 37-year-old female patient who received a kidney transplant 6 months before was diagnosed with novel coronavirus pneumonia. The patient’s symptoms (such as fever, chills, dry cough, muscle aches), laboratory tests (such as decreased white blood cell count, elevated liver enzymes and D-dimer, positive viral nucleic acid test), and chest CT (multiple left lower lung plaque ground glass shadow) were similar to those of non-transplanted novel coronavirus pneumonia patients. In terms of treatment, because the immunity of kidney transplant recipients has been suppressed for a long time, it is a very common strategy to suspend the use of immunosuppressive agents. Therefore, the patient immediately discontinued the immunosuppressive agent after admission, so that she could restore immunity against infection in a short time. At the same time, the use of glucocorticoids was also very important. Its immunosuppressive and anti-inflammatory effects played a large role in the treatment process.In addition, prophylactic antibiotics was needed, and nephrotoxic drugs should be used with caution. Finally, following discounting the use of immunosuppressant and a low-dose glucocorticoid-based treatment regimen, COVID-19 in this renal transplant recipient was successfully cured. The cure of this case was of great significance, and this adjuvant nonspecific antiviral therapy could provide a template for the treatment of other such patients.
