外周T細胞淋巴瘤(PTCL)是一組起源于胸腺的成熟T細胞的淋巴增殖性疾病。與B細胞淋巴瘤相比,PTCL侵襲性更強、預后更差,治療上缺乏統一的標準治療方案。傳統化學治療方案CHOP(環磷酰胺+長春新堿+多柔比星+潑尼松)及CHOP類似方案對PTCL療效欠佳。造血干細胞移植在PTCL中的應用有限。因此PTCL的治療正成為淋巴瘤治療中最具前沿性和挑戰性的研究領域。隨著臨床研究的不斷進展,靶向藥物在PTCL的治療上顯示出一定的前景。該文就其靶向治療進行了綜述。

目的了解精神科護理人員的心理健康狀況及其影響因素。
方法于2012年11月-12月選取成都市2所精神專科病房,分層隨機抽取80名精神科病房護理人員,采用癥狀自評量表(SCL-90)及自制基線調查表進行統一測評并進行統計分析。
結果開放式精神病房相比封閉式病房護理人員在焦慮和恐怖2個因子得分較低(P<0.05),較高教育程度的護理人員在敵對因子得分較高(P<0.05)。
結論應加強對精神科護理人員心理健康狀況的關注,而對于病情穩定的精神障礙患者安置于開放式病房有利于精神科護理人員的心理健康發展。

噬血細胞綜合征(HPS),又稱噬血細胞性淋巴組織細胞增生癥,是一種由多種致病因素導致的單核-巨噬細胞系統反應性增生,釋放大量的細胞因子,引起嚴重器官功能損害的疾病。腫瘤相關性HPS多見于淋巴瘤,又稱淋巴瘤相關噬血細胞綜合征(LAHS)。臨床特征主要有發熱、肝脾腫大、血細胞減少、凝血障礙、高鐵蛋白血癥、高三酰甘油血癥、低纖維蛋白原血癥、骨髓及其他臟器出現噬血細胞現象。LAHS病情兇險,病變進展快,預后差。化學療法聯合大劑量皮質類固醇激素及免疫抑制治療是該病的主要治療方案,但療效差,患者多在短期內死亡。該文就LAHS的發病機制、臨床特征、診斷、治療等方面的研究進展加以綜述,旨在提高對LAHS的認識,指導臨床治療。

從近年來針灸、藥物、物理療法、手術等方面,對治療脊髓損傷后神經源性膀胱的臨床研究進行綜述。脊髓損傷后神經源性膀胱的治療方法眾多,療效確切,綜合療法已成為治療脊髓損傷后神經源性膀胱較為理想的手段。但臨床中還存在著一些問題,有待進一步的改進和完善。

目的:腰椎穿刺術后兩種不同體位對患者舒適度的影響。方法:采用自身前后對照法,將60例結核性腦膜炎患者首次行腰穿術列為對照組;第2次列為實驗組。實驗組術后去枕平臥和抬平頭側臥交替更換體位,對照組術后常規去枕平臥位。觀察兩種體位致患者頭部、腰背部不適、皮膚受壓情況.結果:實驗組患者術后頭痛、腰背痛及皮膚壓紅的發生率明顯低于對照組。結論:實驗組去枕平臥和抬平頭側臥交替更換體位,能顯著減少患者術后的不適。

Objective To investigate the effect of N-methyl-N-nitrosourea (MNU) on expressions of interphotoreceptor retinoid-binding protein (IRBP) and recoverin in rat retinal. Methods Thirty female SpragueDawley (SD) rats were randomly divided into five groups, including normal control group, and MNU treatment one day, three days, seven days and 10 days groups, each group had six rats. Rats in MNU-treatment groups received a single intraperitoneal injection of 40 mg /kg MNU, while rats in the normal control group received intraperitoneal injection of saline 5 ml/kg. Reverse transcription-polymerase chain reaction (RT-PCR) and immunofluorescence were used to detect the retinal expression of IRBP and recoverin. Results RT-PCR results indicated that retinal IRBP levels decreased after MNU injection compared with normal control (P<0.01),while recoverin levels increased (one day: P>0.05; three days: P<0.05; seven days: P<0.5; 10 days:P<0.05). Immunofluorescence assays demonstrated that normally IRBP protein is mainly in the inner and outer segments of photoreceptors. After MNU treatment, IRBP protein was detected in all retinal layers but much faint. Recoverin was expressed in the inner nuclear layer, inner plexiform layer and ganglion cell layer, and its expression was increased after MNU injection. Conclusion MNU suppresses IRBP expression and promotes recoverin expression in rat retina.
