AIM: To investigate if there is any published evidence of impaired quality of life in conditions which are corrected by oculoplastic surgery and whether there is proven benefit in the quality of life such procedures. ·METHODS: We searched a number of databases to determine the level of evidence available for common conditions amenable to oculoplastic surgery. Search terms concentrated on quality of life measures rather than anatomical correction of deformities. ·RESULTS: The level of evidence available for different conditions was very variable. Certain conditions had extensive research documenting reduction in quality of life,with some evidence for improvement after surgery. Some other common conditions had little or no evidence supporting of reduction in quality of life to support the need for surgery. ·CONCLUSION: The evidence is sparse for quality of life improvement after some of our most commonly performed procedures. Many of these procedures are now being identified by primary care trusts(PCTs) as of "low clinical value",and are no longer being routinely commissioned in certain parts of the UK. There is a need to address this lack of evidence to determine whether oculoplastic surgery should continue to be commissioned by PCTs.

The effect of first thinning and pruning on height, diameter at breast height （DBH）, and volume growth was studied in individual trees of Pinus patula Schiede and Deppe in Chongoni Plantation, using four plots for thinning trials. Each of the plots was 0.5 ha and subjected to one of the fol- lowing silvicultural treatments： first thinning and pruning, first thinning and no pruning, pruning and no thinning, and control （no pruning and no thinning）. The silvicultural treatments were randomized in four replicates. Fourteen years after planting, the following parameters were measured including total height, DBH, and volume. The highest DBH and volume growth was observed in thinning and pruning, while the highest growth in height was observed where there was pruning and no thinning. Clearly, both thinning and pruning are an important manage- ment option in pine species plantations in Malawi to maximize the increase in volume productivity.

17β-Estradiol （E2） is an endocrine disrupting chemical of harm to both animals and human beings at a low concentration level （ng/L）. It cannot be completely removed by wastewater treatments, and is often detected in both environment and drinking waters. The purpose of this feasibility study, towards environmental engineering in the field of water analysis and treatment, was to remove E2 by extraction using non-imprinted polymer （NIP） submicron particles. Experimental results showed that 0.5 mg/L of E2 could be completely extracted by adding 10 mg of NIP particles directly into 10 mL of water. However, the extraction efficiency decreased to 64% for 100 mL of water. prefilling the NIP particles inside a membrane filter showed a potential for water treatment of a large volume, requiring no effort to distribute the particles uniformly in the water. High extraction efficiency （80 ± 10）% for E2 was achieved for 100 mL of water. A total mass of 0.29 mg E2 was extracted from 1000 mL of water containing 0.8 mg/L E2 （by using only 10 mg of NIP particles）. Both efficiency and mass capacity can be increased, by scaling up the amount of NIP particles, towards environmental engineering applications.

Purification of the total DNA extracted from activated sludge samples was studied. The effects of extraction buffers and lysis treatments （lysozyme, sodium dodecyl sulfate （SDS）, sonication, mechanical mill and thermal shock） on yield and purity of the total DNA extracted from activated sludge were investigated. It was found that SDS and mechanical mill were the most effective ways for cell lysis, and both gave the highest DNA yields, while by SDS and thermal shock, the purest DNA extract could be obtained. The combination of SDS with other lysis treatment, such as sonication and thermal shock, could apparently increase the DNA yields but also result in severe shearing. For the purification of the crude DNA extract, polyvinyl polypyrrolidone was used for the removal of humic contaminants. Cetyltrimethyl ammonium bromide, potassium acetate and phenol/chloroform were used to remove proteins and polysaccharides from crude DNA. Crude DNA was further purified by isopropanol precipitation. Thus, a suitable protocol was proposed for DNA extraction, yielding about 49.9 mg （total DNA）/g volatile suspended solids, and the DNA extracts were successfully used in PCR amplifications for 16S rDNA and 16S rDNA V3 region. The PCR products of 16S rDNA V3 region allowed the DGGE analysis （denatured gradient gel electrophoresis） to be possible.
