目的:观察仰卧位关节腔注射治疗膝骨性关节炎(osteoarthritis,以下简称膝OA)的临床疗效并探讨护理方案.方法:选取116例符合诊断标准的膝OA患者,所有患者采用仰卧位髌骨外缘入路关节腔注射玻璃酸钠注射液,1次/周,连续5周为一个疗程,并于注射前后给予护理及康复指导.治疗前及治疗后应用视觉模拟评分(visual ana-log scale,VAS)、WOMAC骨关节炎指数、肿胀、压痛积分进行评分,以评价疗效.结果:治疗前后VAS疼痛评分、WOMAC骨性关节炎指数、肿胀、压痛指数均有显著性意义(P<0.05).经治疗后,临床控制2例(1.72%),显效26例(22.41%),有效76例(65.52%),无效12例(10.35%).结论:仰卧位关节腔注射治疗并配合护理康复能明显改善膝OA临床症状,且临床操作安全、方便.     

钛夹法和钛夹法腹腔镜阑尾切除术治疗小儿阑尾炎的对比分析

目的：分析无钛夹法腹腔镜阑尾切除术在小儿阑尾样治疗中的临床意义．方法：对比分析无钛夹法和钛夹法腹腔镜阑尾切除术在小儿阑尾炎手术中的特点．结果：无钛夹法和钛夹法腹腔镜阑尾切除术在小儿阑尾炎的治疗中,在手术时间、手术操作、手术费用、术后早期恢复中,无明显差异;但无钛夹法没有体内金属异物残留,对患儿远期的生理和心理上的影响明显减少．结论：无钛夹法腹腔镜阑尾切除术与钛夹法相比,手术操作和近期疗效基本相同,但远期对患儿生理和心理的影响上有一定优势,值得临床推广．表1,参6．     

脑干血管母细胞瘤的外科治疗

脑干血管母细胞瘤位置深,解剖结构复杂,但临床症状轻微,多以头痛为首发症状,发现肿瘤时体积多已较大.手术是目前治疗脑干血管母细胞瘤的主要手段.手术前应对肿瘤进行适当的处理,选择合适的手术时机,手术中依据病变部位采取适当的手术入路,尽量彻底地切除病变.神经影像学新技术为术者了解神经传导束的位置及走行提供了重要的信息.参24.     

术后早期急性炎性肠梗阻的观察及护理

目的探讨术后早期急性炎性肠梗阻（EPII）的临床表现、治疗方法及护理．方法回顾性分析86例EPII的临床表现、治疗及护方法．结果EPII发生在术后4-21d,肠蠕动一度恢复,继而又出现呕吐,腹胀,腹痛等肠梗阻表现,大部分病例非手术治愈,仅少部分手术治疗．结论EPII以非手术治疗为主,积极的心理干预及护理有助于疾病康复．表2,参14．     

温泉沐浴可治病

温泉其实就是一种温热的地下水,当降水渗入地下深处,受到地下高温、高压的长期作用,逐渐溶解了岩层中的化学成分,而后遇到地层裂缝并涌出地表时,就形成了温泉。当地下热水能经常得到地表水的补充时,温泉水就会源源不断地流出来。温泉一般根据水温可分为:温泉(水温为25～37℃)、热泉(水温在38～42℃)和高热泉(水温为42℃以上)几类。根据水质所含的化学成分不同,温泉又可分为碳酸泉、重碳酸泉、硫酸盐泉、硫黄泉、硫化氢泉、碘泉、氡泉等类型。温泉的医疗作用,在我国的许多古籍中早有记载,如汉代张衡《温泉碑》中即提到:“有疾厉兮,温泉泊焉。”郦道元《水经注》里曾提到:“大融山石出温场,沐浴可治病。”根     

第二次受伤能享受工伤医疗待遇吗？

编辑同志:我单位1名职工因工伤右小腿骨折,经治疗恢复拆除钢板后15日左右,在家活动时右脚不慎扭了一下,工伤处又被折断。请问能否享受工伤待遇给予治疗。李浩李浩先生:来函收悉。根据函中所反映的情况,我们认为,该职工第二次受伤是第一次工伤的延续,理应享受工伤医疗待遇。第二     

Variation of peroxidase isoenzyme and biofilm of Phanerochaete chrysosporium in continuous membrane bioreactor for Reactive Brilliant Red X3-B treatment

The influence of a Reactive Brilliant Red X-3B (RBR X-3B) dye on the peroxidase isoenzyme of Phanerochaete chrysosporium was determined, and the biofilm structure in a white rot fungal continuous membrane bioreactor (MBR) was also investigated by scanning electron microscope (SEM). The variation of peroxidase isoenzyme and the decolorization rate in the continuous MBR were evaluated. The results showed that the 100 mg/L RBR X-3B could stimulate the production of the peroxidase isoenzyme in the shaking-flask culture. In addition, two new peroxidase isoenzyme bands with relative mobility (Rf) value of 0.27 and 0.28 appeared, but the activity was lower than the blank control of 11 d. In the continuous MBR, the system worked stably during the first 60 d, the main peroxidase isoenzyme bands existed and three new bands with Rf value of 0.10, 0.27, and 0.28 appeared. Meanwhile, the biofilm grew well and the average decolorization rate could reach 90.6%. But the bands of peroxidase isoenzyme decreased rapidly at day 65, only two bands with Rf value 0.24 and 0.26 existed, and the decolorization rate decreased to 78.3%. Therefore, 5 bottles of P. chrysosporium mycelial pellet were added into the MBR, and then the activity of the peroxidase isoenzyme and the decolorization rate had a slight recovery. Finally, the decolorization rate finally decreased to 75.2%. These results contribute to a comprehensive understanding of the variation of peroxidase isoenzyme and biofilm in continuous MBR by white rot fungi.     

Role of quantum dots nanoparticles in the chemical treatment of colored wastewater: Catalysts or additional pollutants

The objective of the study was to investigate the presence and the activity of quantum dots nanoparticles in colored wastewaters. The special interest is devoted to the investigation of their role in the typical treatment of water or wastewater, studying their influence on the effectiveness of applied treatments methods. The standard chemical processes for water treatment and disinfection (direct UV photolysis and direct ozonation) were applied for the degradation of colored organic pollutant, reactive azo dye, in the presence/absence of CdSe/ZnS core-shells quantum dots. The obtained results indicated that investigated nanoparticles inhibit the overall efficiency of applied processes, especially in the case of direct UV photolysis, although catalytic effect might be expected in part due to the semiconductor nature of quantum dots. Such results lead to a conclusion that CdSe/ZnS nanoparticles behave as additional pollutants in the system. They should be removed from the system prior the treatment, because their presence could decrease the efficiency, i.e., prolong the time of treatment and correspondingly increase the costs of the treatment process.
