苏励教授治疗强直性脊柱炎经验介绍

苏励教授认为，脊柱在人体的位置处于皮里膜外，半表半里。强直性脊柱炎病在脊柱，故痰瘀之邪也盘踞在半表半里。治疗宜内清外透结合，在清里基础上外透，使邪有出路，从而清除盘踞在半表半里之邪实。并结合外治法以增加疗效。

Global transcriptional profiling demonstrates the combination of type I and type II interferon enhances antiviral and immune responses at clinically relevant doses.

A role for type II interferon (IFN-gamma) in resolving viral infection is suggested by the correlation of hepatitis C virus (HCV) clearance with enhancement of IFN-gamma-producing activated T cells in the resolution of acute HCV infection. Using vesicular stomatitis virus (VSV), a synergistic direct antiviral effect was documented using IFN-gamma1b and a potent, consensus type I IFN (IFN alfacon-1). Global expression profiling following EC50 exposure to IFN alfacon-1, IFN-gamma1b, or a cocktail of the two allowed the antiviral state to be correlated with induction of a subset of IFN-stimulated genes (ISGs). Genes identified through this analysis corresponded to classic antiviral components, ISGs more recently associated with direct antiviral functions, as well as expressed sequence tags (ESTs) and hypothetical proteins. The magnitude of these antiviral EC50-correlated expression events in human hepatoma (Huh7) cells exposed to clinically relevant doses of IFN alfacon-1, IFN-gamma1b, or a cocktail of the two was also probed because the standard of care for patients with chronic hepatitis C is type I IFN-containing regimens. Relative to type I IFNs used alone, the addition of type II IFN caused enhanced expression not only of many of the genes correlated with the direct antiviral state but also of genes involved in (1) antigen presentation to cytotoxic T lymphocytes (CTLs), (2) macrophage, natural killer (NK), and T helper 1 (Th1) cell recruitment and activation, (3) complement system function, (4) apoptosis, and (5) ISGs with unknown functions. As many of these processes are correlated clinically with resolution of chronic HCV infection, the combined use of these IFNs could display a beneficial effect on viral clearance in patients infected with HCV and other viruses through enhancement of one of these processes or of the direct antiviral state.     

FOLFOX4与替加氟替代方案对晚期胃癌疗效的对比研究

目的:对比观察FOLFOX4方案与替加氟替代方案治疗晚期胃癌的疗效和不良反应.方法:经病理或细胞学确诊的晚期胃癌患者75例,按收治的时间顺序交叉分入FOLFOX4组(A组)或替加氟替代组(B组),两方案均至少连用3周期评价疗效.A组:OXA 85mg/m2,静滴2h,第1天;LV 200mg/m2,静滴2h,第1、2天;5-FU 400mg/m2,静推,然后600mg/m2,22h静脉维持,第1、2天;2周重复,14天为1个周期.B组:OXA 130mg/m2,静滴2h,第1天;LV 200mg/m2,静滴2h,第1-5天;FT-207 800mg/m2,静滴3h,第1-5天;3周重复,21天为1个周期.结果:研究对象共75例.A组39例,总有效率(CR + PR)41.0%,其中初治患者总有效率55.6%;复治患者的总有效率28.6%.B组36例, 总有效率38.9%,其中初治患者总有效率 50.0%;复治患者的总有效率30.0%.两组总有效率比较均无统计学差异.不良反应主要是白细胞减少、恶心呕吐、神经感觉毒性等,A组白细胞下降发生率和消化系统不良反应发生率均明显高于B组(P均＜0.05).两组均无化疗相关死亡.结论:FOLFOX4方案与替加氟替代方案均为治疗晚期胃癌有效的方案,FOLFOX4方案总有效率稍高,不良反应较替加氟替代方案重,但可耐受.建议晚期胃癌初治可选用FOLFOX4方案,而其中年龄偏大,体质欠佳的患者宜选替加氟替代方案.

腮腺手术中耳大神经后支保留的临床意义

目的 探讨腮腺手术中耳大神经后支保留的可行性、方法及临床价值。方法 我们对48例腮腺肿瘤患者，按常规隐蔽切口腮腺手术方法进行治疗，保留或不保留耳大神经后支。分别于术后10d及1、6、12个月进行随访，检测耳廓上部、耳垂、耳下区、耳前区和耳后区的触觉、痛觉，并观察其感觉变化情况。结果 48例中35例耳大神经后支保留，耳廓上部及耳后区感觉无减退。术后早期耳前、耳垂及耳下区感觉有不同程度的减退，以耳前区最明显，随着时间延长症状逐步好转，6个月时感觉接近正常。另13例耳大神经切断患者感觉减退症状更加明显，恢复时间延长。结论 腮腺手术中耳大神经后支保留是可行的，所采用的方法可靠，可减轻局部麻木感，提高患者术后早期生活质量，降低神经切断后产生局部永久性麻木的可能性。     

Endoscopic pH monitoring for patients with suspected or refractory gastroesophageal reflux disease.

BACKGROUND: Wireless pH studies can offer prolonged pH monitoring, which may potentially facilitate the diagnosis and management of patients with gastroesophageal reflux disease (GERD). The aim of the present study was to evaluate the detection rate of abnormal esophageal acid exposure using prolonged pH monitoring in patients with suspected or refractory GERD symptoms. METHODS: Patients undergoing prolonged ambulatory pH studies for the evaluation of GERD-related symptoms were assessed. Patients with a known diagnosis of GERD were tested on medical therapy, while patients with suspected GERD were tested off therapy. The wireless pH capsules were placed during upper endoscopy 6 cm above the squamocolumnar junction. RESULTS: One hundred ninety-one patients underwent a total of 198 pH studies. Fifty ambulatory pH studies (25%) were excluded from the analysis: 27 patients (14%) had insufficient data capture (less than 18 h on at least one day of monitoring), 15 patients had premature capsule release (7%), seven were repeat studies (3.5%) and one had intolerable pain requiring capsule removal (0.5%). There were 115 patients undergoing pH studies who were off medication, and 33 patients were on therapy. For the two groups of patients, results were as follows: 32 (28%) and 22 (67%) patients with normal studies on both days; 58 (50%) and five (15%) patients with abnormal studies on both days; 18 (16%) and three (9%) patients with abnormal studies on day 1 only; and seven (6%) and three (9%) patients with abnormal studies on day 2 only, respectively. CONCLUSIONS: Prolonged 48 h pH monitoring can detect more abnormal esophageal acid exposure but is associated with a significant rate of incomplete studies.     

胰岛素瘤的诊断和治疗：附137例报告

目的总结胰岛素瘤的诊断方法和外科治疗效果。方法回顾性分析近26年来收治的胰岛素瘤137例患者的临床资料。结果男77例,女60例。137例均具有典型的Whipple三联症。B超,CT,MRI检查的阳性率分别为35.1%,67.9%,58.1%。126例手术治疗患者中,102例(80.9%)行胰岛素瘤摘除术,4例(3.2%)行胰十二指肠切除术,16例(12.7%)行胰体尾切除术,另外4例(3.2%)行开腹探查术。切除的122例肿瘤中,良性占96.7%,恶性3.3%;单发肿瘤98.4%,多发1.6%。86.9%肿瘤直径≤2.0cm。13.1%肿瘤位于胰头;位于胰体和胰尾者分别为46.7%和40.2%。结论Whipple三联症,结合IRI,IGR,C-肽,以及胰岛素原的检测水平,可作为胰岛素瘤的定性诊断依据。胰岛素瘤的定位诊断仍很困难,联合应用多种影像学检查方法有助于提高检出率。治疗首选肿瘤摘除术,如果术中探查未能找到肿瘤,不宜盲目行胰体尾切除术,应排除其他原因所致低血糖症,同时进一步完善影像学检查方法,明确定位后,再考虑二次手术治疗。     

P16INK4、PCNA在肺癌中表达的研究

目的 通过检测肺癌组织中p16、PCNA的表达，探讨其在肺癌发生发展中的作用及相互关系。方法 采用S—P免疫组化方法，检测83例肺癌标本及15例正常肺组织标本中P16^INK4和PCNA的表达。结果 P16^INK4和PCNA在正常肺组织和肺癌组织中表达的阳性率存在显著性差异。P16^INK4表达的阳性率在小细胞癌与非小细胞癌之间有显著性差异。PNTM分期高的肺癌标本P16^INK4及PCNA表达阳性率显著高于分期低的肺癌标本。不同分化程度的肺癌组织P16^INK4及PCNA表达阳性率有显著性差异。结论 肺癌的发生与P16^INK4的低表达和PCNA的高表达有关。而P16^INK4的表达与肺癌的组织学类型、分化程度、临床分期有关；PCNA的表达与肺癌的分化程度、临床分期有关。
