Background: Cryopreserved tracheal allograft has been used successfully for esophageal replacement in the canine model. The working hypothesis was cryopreservation decreases antigenicity but epithelial desquamation remains. However, cryopreservation of human tracheal samples collected at tracheostomy, resulted in no significant desquamation. The aim of this study was to examine the extent of desquamation of the epithelial layer of cryopreserved animal tracheas and find a reason for decreased antigenicity of cryopreserved canine and pig’s trachea. Methods: 5 cm long tracheal segments were removed from 6 dogs and 125 pigs and stored in liquid nitrogen for 21 days. Cross section samples were taken from the end of the segment, 1 cm from the end and at the middle of the segment. Histological examination was performed using haematoxyllineosin and MHC-II antigen specific antibody staining. Changes in histological structure were analyzed. Results: General histological morphology of samples changed after cryopreservation. The percentage of intact epithelium and the overall intensity of immune-staining increased significantly from the ends to the middle of the segments, but the intensity of immune-staining showed no difference in the remaining epithelial cells. Conclusion: Cryopreservation damages the epithelial cells, but does not influence the cell’s antigenicity or cause desepithelisation. The main effect is a retraction of the epithelial layer from the ends to the midpart and this effect may be protection against organ rejection. Based on our canine and pig results a 5 cm, long tracheal segment seems to be a promising organ for human esophageal replacement.

Breakage of K-wires and stainless steel wires which are used for fracture fixation is not uncommon, but migration is rare. We report a case of migration of bro- ken K-wire used for patella tension band wiring to the popliteal fossa. The broken hardware was removed surgically. We would like to suggest that K-wire and wire fixation used for treatment ofpatellar fractures can migrate into the posterior compartment of the knee and cause clini-cal symptoms. Close clinical and radiological follow-up af- ter internal fixation to identify the presence of hardware breakage or movement and removal of wires once fracture has united can avert such complications.

建立了流动注射(FI)在线编结反应器(KR)预富集与火焰原子吸收光谱(FAAS)联用测定水样中痕量镍的吸力洗脱方法。洗脱过程依靠蠕动泵的吸力而不是推力实现洗脱剂的输送,明显降低了被分析物在洗脱过程中的分散,提高了原子吸收信号峰值(A)和浓集系数(EF)。增加了样品溶液排空步骤,保证了每次实验的准确性和重复性。进样流速6.0 mL/min,进样时间60 s,测定水样中的镍,EF由传统洗脱法的4.9提高到9.8,检出限为3.1μg/L,测样频率为41 h-1,相对标准偏差(RSD,n=11)为2.2%,以体积分数0.01%的三乙醇胺(TEA)为掩蔽剂,在水样中的回收率为95.5%～97.8%。

烟道气脱硫废水排污处理和零液体排放

已经安装或将要安装FGD系统（烟道气脱硫系统）的燃煤电厂，其FGD排污废水的排放正面临严格的限制。但因FGD废水中存在着各种污染物的独特混合物，使得可用的处理方案非常有限。越来越多的电厂不得不扩展其传统的物理化学处理法，增加以下措施：1）好氧生物处理系统，用于去除二元酸中的BOD；2）厌氧生物处理系统，用于去除硒酸盐；3）零液体排放。二元酸（DBA）是一种用在洗涤器中起缓冲、防腐蚀、减少石灰石的使用和阻垢作用的添加剂。它是由己二酸、戊二酸和丁二酸组成的混合物。好氧菌很快地将DBA消化，以满足废水排放要求。为了满足FGD废水指标的另一个要求是降低废水对硒的限制。这些限制可采用厌氧生物处理，通过脱氮菌和硫酸盐还原菌（SRB）的作用完成。SRB利用硒酸盐和硫酸盐中的氧进行呼吸。在该过程中，硒酸盐被还原成元素硒，通过澄清去除。除了这些以外，还可能要求有自己的ZLD装置，作为一种满足许可证要求的方法，避免排放。本报告重点关注FGD废水中的有问题的污染物，概述正在开发或已经工业应用的各种方案，以便应对不断增长的FGD废水处理需求。

Patient satisfaction is a goal of effective health care delivery and its assessment is important to the improvement of health care, especially in the context of a more consumerist culture. Patient education and information has been shown to improve patient satisfaction with care. Lack of sufficient patient information (specifically related to post-discharge care) was identified in our patient population by means of a broad ranging post-discharge satisfaction survey. Targeted intervention, in the form of a discharge information sheet for patients, was trialled with the aim of improving specific satisfaction parameters related to post-discharge care, and overall patient satisfaction. Patient satisfaction was measured for six months before and after the intervention, and data from both groups compared. There was no statistically significant difference in patient satisfaction directly related to the provision of the additional discharge information or overall patient satisfaction between the two groups. Providing patients with specific information alone at discharge is not sufficient to improve overall or discharge-specific patient satisfaction. More active interventions may be required.

A 67-year-old male presented with a gradually progressive low back pain of 2 years duration. The patient was leading a retired life and there was no history of chronic fever or significant trauma. There was no radiation of pain or any features suggestive of claudication. There was no history of any comorbidity. The pain was aggravated with extension of the spine and relieved with flexion. There was no swelling or neurological deficit, but muscle spasm was present. Radiographs of the spine revealed degenerative changes in the lumbosacral spine, along with articulation of spinous processes at in lumbar spine at all levels level suggestive of Baastrup's disease, commonly known as "kissing spine". Routine blood investigations were within normal limits. The patient was managed conservatively. He was given a week's course of analgesics and muscle relaxants and then started on spinal flexion exercises, with significant improvement being noted at 6 months follow up.

Objective: To analyse the use of BMI and bioelectrical impedance analysis (BIA) in assessment of adiposity among young and elderly population. Materials and methods: Age, height, weight and percent body fat (PBF) of 101 young and 276 elder subjects were recorded. PBF was measured directly by BIA instrument (PBFb) and also calculated from BMI (PBFf). The classification of subjects into underweight, normal, overweight and obese was based on the age- and sex-specific BMI cutoff values and PBFb following standard guidelines. Results: The calculated mean BMI values of young and old age groups were statistically same. PBF was significantly high in elder subjects. There was no statistical difference in mean PBFb and PBFf in young subjects but the difference was significant in elder subjects. The PBFf values were highly correlated (r: 0.92 to 0.96) with PBFb values in young age groups unlike elder groups of both males and females. PBFb based categorization of subjects’ presented totally different scenario compared to results obtained by BMI analysis to assess adiposity. Conclusion: The cases such as increasing fatness with aging even when BMI remains constant, the causes of country or ethnic differences in BMI analysis, poor correlation in PBFb and PBFf values in elder age group emphasize on the limitations of BMI based analysis. PBFb within limitations seems to be an improved phenotypic characteristic over BMI.
