目的探讨艾滋病患者淋巴结组织中CD4 CD25 调节性T细胞的表达、分布及其与病理改变的相关性。方法对22例活检及13例尸体解剖的HIV/AIDS患者的淋巴结进行组织学观察和病理分期,采用免疫组织化学法对淋巴结组织中的CD4 CD25 调节性T细胞特异性标记物FoxP3进行检测。结果35例艾滋病患者的淋巴结中,1～4期分别有5、4、14和12例。所有淋巴结组织中均检测出FoxP3的阳性表达;在1、2期病变淋巴结内,FoxP3阳性细胞数量较多,分布于滤泡间区和副皮质区;3、4期随着淋巴细胞的数量衰竭,阳性细胞数量的减少更加明显。结论艾滋病患者淋巴结中存在有CD4 CD25 调节性T细胞,随着淋巴结病变的进展其数量减少或耗竭。

Evaluation of plasma retinol-binding protein as a surrogate measure for plasma retinol concentrations

Fasting growth hormone (GH) levels and GH responses to exercise were studied in normally menstruating women and in women taking oral contraceptives in order to find out whether the GH levels were related to the menstrual cycle or changed by oral contraceptives. The GH response to exercise was found to be higher when exercise was done in the midcycle period than when it was done at other points of time during the normal menstrual cycle. Fasting GH levels were unchanged throughout the menstrual cycle. Fasting GH levels and GH responses to exercise performed outside the midcycle period were identical in normally menstruating women and in women taking oral contraceptives. In conclusion, the GH response to exercise, but not fasting GH levels, were related to the menstrual cycle. The estrogen and progestin components of the contraceptives used in this study were balanced in such a way that the growth hormone levels and growth hormone responses to exercise were not changed by long-term therapy with these drugs.

目的评价股腘动脉硬化病变腔内治疗的近期临床疗效。方法回顾性分析2008年1月～2009年6月收治的55例(57条患肢)TASCC型股腘动脉病变患者的临床资料,其中50例(52条患肢)施行经皮血管腔内球囊成形术和支架植入术,应用踝/肱指数(ABI)、Fontaine分期、保肢率和通畅率综合评估治疗效果。结果腔内治疗技术成功率91.2%,围手术期死亡率5.3%,截肢率3.5%。腔内治疗明显提高患肢足背动脉AB(I0.38±0.17vs0.68±0.39,P0.01)和胫后动脉的AB(I0.41±0.18vs0.72±0.50,P0.05)。重症下肢缺血(CLI)的患肢数由治疗前的36条(63.2%)减少至治疗后的19条(36.5%),差异具有统计学意义(P0.01)。平均随访(11.4±6.4)个月,随访期足背动脉和胫后动脉ABI分别为0.48±0.38和0.61±0.47,与术前和术后相比,差异均有统计学意义(P0.05);随访期CLI的患肢数(12条,29.3%)与治疗前(36条,63.2%)比较,差异有统计学意义(P0.05),与治疗后(19条,36.5%)比较,差异无统计学意义(P0.05)。结论腔内治疗TASCC型股腘动脉硬化病变创伤小,近期临床疗效满意。     

Upregulation of type I interleukin−1 receptor after traumatic spinal cord injury in adult rats

Post-traumatic inflammation response has been implicated in secondary injury mechanisms after spinal cord injury (SCI). Interleukin-1 (IL-1) is a key inflammatory mediator that is increasingly expressed after SCI. The action of IL-1 is mediated through its functional receptor, type I interleukin-1 receptor (IL-1RI). However, whether this receptor is expressed after SCI remains to be elucidated. In the present study, the temporospatial expression of IL-1RI was detected in rats that received a moderate contusive SCI (a 10 g rod dropped at a height of 12.5 mm) at the ninth to tenth thoracic vertebral level using a widely used New York University impact device. Our study demonstrated that IL-1RI was slightly increased at 4 h post-injury compared to the normal or sham-operated controls, reached the peak at 8 h at mRNA level (4.44-fold, P<0.01) and 1 d at protein level (2.62-fold, P<0.01). IL-1RI remained at its elevated levels for a relatively long duration (4 h–7 days). Spatially, IL-1RI was observed throughout the entire length of a 10 mm-long cord segment containing the injury epicenter. Colocalization of IL-1RI was found in neurons, oligodendrocytes, astrocytes, and activated microglia. Our results suggest that the elevated expression of IL-1RI after SCI may contribute to posttraumatic inflammation responses of IL-1.
