克深2气藏储层裂缝带发育特征及其与产量的关系

塔里木盆地内存在多套烃源岩, 油气资源十分丰富。早寒武世早期, 塔里木盆地沉积了一套以页岩(或泥岩) 为主的黑色岩系。通过对此套页岩层系在野外露头、钻孔资料岩性和地层分析, 结合前人的研究成果, 明确了其分布范围：主要分布在盆地内北部坳陷, 呈西薄东厚趋势。有机碳含量分析表明, 此黑色页岩是一套优质有效烃源岩, 目前演化程度较高, 以生成天然气为主, 是塔里木盆地重要烃源岩之一。     

Disruption of the Candida albicans CYB5 gene results in increased azole sensitivity

Sterol synthesis in fungi is an aerobic process requiring molecular oxygen and, for several cytochrome-mediated reactions, aerobically synthesized heme. Cytochrome b(5) is required for sterol C5-6 desaturation and the encoding gene, CYB5, is nonessential in Saccharomyces cerevisiae. Cyb5p and Ncp1p (cytochrome P-450 reductase) appear to have overlapping functions in this organism, with disruptions of each alone being viable. The cytochrome P-450 reductase phenotype has also been shown to demonstrate increased sensitivity to azole antifungals. Based on this phenotype, the CYB5 gene in the human pathogen Candida albicans was investigated to determine whether the cyb5 genotype was viable and would also demonstrate azole sensitivity. Sequential disruption of the CYB5 alleles by direct transformation resulted in viability, presumably conferred by the presence of a third copy of the CYB5 gene. Subsequent disruption procedures with a pMAL2-CYB5 rescue cassette and a CYB5-URA3 blaster cassette resulted in viable cyb5 strains with no third copy. The C. albicans CYB5 gene is concluded to be nonessential. Thus, the essentiality of this gene and whether we observed two or three alleles was dependent upon the gene disruption protocol. The C. albicans cyb5 strains produced a sterol profile containing low ergosterol levels and sterol intermediates similar to that reported for the S. cerevisiae cyb5. The C. albicans cyb5 shows increased sensitivity to azoles and terbinafine, an inhibitor of squalene epoxidase, and, unexpectedly, increased resistance to morpholines, which inhibit the ERG2 and ERG24 gene products. These results indicate that an inhibitor of Cyb5p would not be lethal but would make the cell significantly more sensitive to azole treatment.     

Does additional weekend and holiday physiotherapy benefit geriatric patients with hip fracture? — A case-historical control study

Objective:To evaluate the new service model of additional weekend and holiday physiotherapy (PT) by comparing functional outcomes and hospital length of stay between a group of geriatric patients with hip fracture receiving daily PT training and a group of geriatric patients with hip fracture receiving weekdays PT training.Methods:A retrospective case-historical control chart review was conducted and a total of 355 patients were identified. Between-group comparisons were done on functional outcomes including Modified Functional Ambulation Classification (MFAC), Elderly Mobility Scale (EMS), Modified Barthel Index (MBI) and process outcome in terms of length of stay (LOS) in hospitals.Results:With similar characteristics, patients who received weekend and holiday PT training had a significant higher percentage of MFAC Category III and a significant lower percentage of MFAC Category II (p=0.015) and significant higher MBI scores (mean±standard deviation, median; Study group: 47.4±19.6 points, 51 points; Control group: 43.0±20.0 points, 43 points; p=0.042) upon admission to rehabilitation hospital. A similar trend in EMS scores (Study group: 8.2±5.5 points, 7 points; Control group: 8.4±6.1 points, 6 points; p=0.998) and MBI scores (Study group: 63.0±23.4 points, 68 points; Control group: 61.2±26.1 points, 64 points; p=0.743) were observed upon discharge from the rehabilitation hospital. The average LOS in acute hospitals remained static (Study group: 7.7±3.9 days, 7 days; Control group: 7.4±5.0 days, 6 days; p=0.192). The average LOS in rehabilitation hospital (Study group: 20.0±5.5 days, 20 days; Control group: 24.3±9.9 days, 23 days; p<0.001) and total in-patient LOS (Study group: 26.7±6.4 days, 26 days; Control group: 30.7±11.2 days, 28 days; p<0.001) were significantly reduced. A higher percentage of days having PT training during hospitalization in rehabilitation hospital was shown with the implementation of new service (Study group: 89.1%; Control group: 65.9%, p<0.001).Conclusion:Additional weekend and holiday PT training in post-operative acute and rehabilitation hospitalization benefits geriatric patients with hip fracture in terms of improved training efficiency, where hospital LOS was shortened with more PT sessions, without any significant impacts on functional outcome.
