细胞核DNA含量测定和AgNOR颗粒计数对预测卵巢囊腺癌患者预后的意义

背景与目的:以往认为,细胞核DNA含量和核仁组成区嗜银蛋白(silver-stainingnucleolarorganizerregion,AgNOR)计数在某些肿瘤中有重要的预后意义,但对卵巢囊腺癌患者的预后意义尚不清楚。为此,本研究探讨该两项细胞增殖参数对预测卵巢囊腺癌患者预后的价值。方法:对42例卵巢囊腺癌切除术的组织标本采用图像分析仪测定核DNA含量和AgNOR颗粒计数,将结果与预后情况进行分析。结果:单因素生存率分析显示,差异有统计学意义的临床变量为FIGO分级、分化程度、残余肿瘤大小、肿瘤转移灶、淋巴结转移情况和年龄、异倍体、DNA指数、AgNOR颗粒计数(P<0.05)。多因素生存率分析显示,DNA指数>1.4、FIGO分级、分化程度和残余肿瘤大小是卵巢囊腺癌的具有统计学意义的预后预测因子。结论:对于卵巢囊腺癌患者来说,细胞核DNA指数可能是有用的预后独立预测因子。     

Gastrointestinal migrating motor complex during early stage of cholesterol gallstone formation in guinea pigs

Objective： To determine the changes of gastrointestinal migrating motor complex （MMC） during the early stage of cholesterol gallstone formation. Methods：Totally 45 healthy adult guinea pigs were randomly and equally divided into 3 groups, that is, normal control, group B （1% cholesterol diet for 2 weeks） and group C （1% cholesterol diet for 4 weeks）. Three pairs of silver electrodes were inserted into the gastric antrum, duodenum and jejunum of every animal respectively. Record of gastrointestinal MMC of these guinea pigs were recorded and analyzed. Gallbladder bile was taken to detect the formation of cholesterol gallstone. Results： There were only 29 guinea pigs living. The MMC cycle time and the duration of phase Ⅱ were prolonged significantly and gradually compared with the control group （P〈0.01）, but the duration of phase Ⅲ became significantly and gradually shorter. Conclusion： During the early stage of cholesterol gallstone formation, the MMC cycle time and the duration of phase Ⅱ are prolonged and the duration of phase Ⅲ is shortened.     

高血压患者动态脉压与颈动脉内膜-中膜厚度关系

目的探讨原发性高血压(EH)患者24h平均脉压(PP)与颈动脉内膜-中膜厚度(IMT)及斑块的关系。方法对135例EH患者进行24h动态血压及颈动脉内膜-中膜厚度(IMT)及斑块的检测。根据脉压≤40mmHg(1mmHg=0.133kPa),40～60mmHg,≥60mmHg,将135例患者分为3组。结果①随着脉压的升高,颈动脉内膜-中膜厚度(IMT)呈明显增厚,且24h平均脉压、白昼脉压、夜间脉压均与颈动脉内膜-中膜厚度(IMT)增厚显著相关。②随着脉压的升高,斑块检出率明显增加。结论脉压的升高在颈动脉结构的改变上起了一定的作用。

Decreased inflammation and augmented expression of trophic factors correlate with MOG-induced neuroprotection of the injured nigrostriatal system in the murine MPTP model of Parkinson's disease

The response of the immune system during injury of the central nervous system may play a role in protecting neurons. We have previously reported that immunization with MOG 35–55 prior to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced injury of the dopaminergic system promotes less dopamine depletion and less dopaminergic damage of neurons in mice. In this study, we evaluate the influence of MOG immunization on the inflammatory reaction that occurs at the place of injury. C57Bl male mice, 2 and 12 months old, received i.p. injections of MPTP (40 mg/kg) and some groups animals also received an additional injection with myelin oligodendrocyte glycoprotein (MOG) 35–55 in CFA 6 days before MPTP administration. MPTP caused a common inflammatory reaction characterized by microglial activation, infiltration of T cells into the substantia nigra and striatum and increased expression of mRNA encoding pro-inflammatory cytokines (IL-1β, TNFα, INFγ) and trophic factors (TGFβ, GDNF). MOG immunization prior to MPTP administration significantly diminished the microglial reaction and reduced the levels of infiltrating CD8+ lymphocytes. The number of CD4+ T cells remained at the same level as in the MPTP group. Expression of pro-inflammatory cytokines was diminished. The mRNA expression of GDNF was significantly higher in the MOG pretreated mice relative to the MPTP group, both in the 2 month old and 12 month old groups. Since MOG immunization prior to MPTP intoxication appears to prevent nigrostriatal injury, the observed decrease of inflammation and increase of GDNF mRNA expression in the injured areas might represent one of the mechanisms of observed neuroprotection.     

甲钴胺穴位注射与物理疗法治疗周围性面神经炎的疗效比较

目的观察甲钴胺穴位注射与物理疗法治疗周围性面神经炎的疗效比较。方法60例周围性面神经炎患者随机分成甲钴胺穴位注射组与物理疗法组,在治疗前和治疗后的第7、14、21、28d运用多伦多分级评分法(Toronto facial grading system,TFGS)评定面神经功能改善情况。结果2组患者治疗后与治疗前的TFGS比较,P<0.05,差异有统计学意义;甲钴胺穴位注射组与物理疗法组在治疗后的第7、14、21d TFGS比较,P<0.05,差异有统计学意义;2组第28d TFGS比较,P>0.05,差异无统计学意义。结论早期使用甲钴胺穴位注射治疗周围性面神经炎能提高疗效,缩短病程。

皮下脂肪组织创伤后脂肪细胞的变化

目的观察脂肪组织创伤愈合的情况,探讨成熟脂肪细胞的变化。方法以杜洛克母猪为实验动物,用滚轴取皮刀在其背部制作脂肪组织切割伤皮瓣,大体观察伤后1、2、4及12周的愈合情况。并于伤后3、7、14及21 d在皮瓣中央处取材,观察切缘及周围成熟脂肪细胞的形态学改变,用酶联免疫吸附法和免疫组织化学方法检测脂肪组织中瘦素和脂联素的表达情况。结果脂肪组织切割伤组皮瓣中央与未创伤处皮肤无异,但皮瓣边缘早期有明显炎症反应,后期则呈典型的疤痕生长。组织学观察发现:脂肪组织创伤后,仍以纤维化愈合为主,但愈合过程中,炎症反应的局灶性及小脂肪细胞出现呈现一定的规律性;与未创伤组相比,脂肪组织创伤后其瘦素及脂联素的表达量均呈下降趋势,但两者的比值在愈合的过程中存在差异。结论脂肪组织创伤后,脂肪细胞表面瘦素及脂联素的表达量下降。早期创缘附近出现大量的小脂肪细胞,可能与脂肪分解有关。     

Insulin Prevents Latent Skin Lesions by Inhibiting the Generation of Advanced Glycation End Products in Streptozotocin-Induced Diabetic Rats

The preventive effect of insulin on latent skin lesions in streptozotocin-induced diabetic rats was investigated. Diabetes was induced in 72 male Sprague–Dawley rats, with 36 rats serving as the control group. Half of the diabetic rats were treated with insulin, and the other half were injected with vehicle. Skin tissues were collected 4, 8, and 12 weeks after the initiation of insulin therapy for measurement of glucose, collagen-related fluorescence and advanced glycation end product (AGE) expression, and histological observation. The diabetic rats exhibited changes in skin tissue, including a decrease in thickness, disappearance of the multilayer epithelium structure, degeneration of collagen fibers, and an increase in the infiltration of inflammatory cells, in addition to a significant increase in blood glucose and AGE expression. These effects were greatly ameliorated by insulin therapy. Insulin therapy in early-stage diabetes mellitus prevents potential skin lesions, possibly by inhibiting AGE formation and inflammatory reactions following glycemic control.

双窥镜法联合钬激光内切开术治疗严重尿道狭窄疗效观察

目的观察双窥镜法联合钬激光内切开术治疗严重尿道狭窄的初期疗效。方法2005年5月至2009年4月,应用双窥镜法联合钬激光内切开术治疗8例尿道狭窄或尿道闭锁,狭窄段长度0.8-2.5cm。结果8例患者均尝试逆行内切开术均无法通过狭窄段,应用双窥镜法联合钬激光内切开术治疗均获成功,术后留置尿管4-6周,拔管后均排尿通畅,无尿失禁。8例患者中7例获随访6.24个月（平均18个月）,其中2例患者无需任何后续治疗,3例需行6-16次尿道扩张（平均11次）以维持正常排尿;2例术后3及4个月再次因尿道狭窄行开放手术治疗。结论双窥镜法联合钬激光内切开术治疗尿道狭窄提高了一期腔内手术的成功率,可作为严重尿道狭窄、尿道闭锁患者的可选微创治疗术式。该术式早期疗效良好,但远期效果不尽满意尚待长期观察。
