This is mainly shown by multi-phase structural evolution, multiple sets of source-reservoir-cap rock combinations, multiple stages of hydrocarbon generation and expulsion from source rocks, multi-cycle hydrocarbon enrichment and accumulation, and multi-phase reservoir adjustment and reconstruction. The enrichment, accumulation and distribution of hydrocarbon is mainly controlled by the source rock kitchen, paleo- anticline, regional cap rock and intensity of tectonic movement. In this paper, the T-BCMS model has been developed to predict favorable areas of hydrocarbon accumulation in complicated superimposed basins according to time and spatial relationships among five key factors. The five factors include unconformity surface representing tectonic balancing （B）, regional cap rock representing hydrocarbon protection （C）, paleo-anticline representing hydrocarbon migration and accumulation （M）, source rock kitchen representing hydrocarbon generation and expulsion （S） and geological time （T）. There are three necessary conditions to form favorable areas of hydrocarbon accumulation. First, four key factors BCMS should be strictly in the order of BCMS from top to bottom. Second, superimposition of four key factors BCMS in the same area is the most favorable for hydrocarbon accumulation. Third, vertically ordered combination and superimposition in the same area of BCMS should occur at the same geological time. The model has been used to predict the most favorable exploration areas in Ordovician in the Tarim Basin in the main hydrocarbon accumulation periods. The result shows that 95% of the discovered Ordovician hydrocarbon reservoirs are located in the predicted areas, which indicates the feasibility and reliability of the key factor matching T-BCMS model for hydrocarbon accumulation and enrichment.展开更多

These cysts often present a diagnostic challenge. Therefore, we performed a review of the recent literature and developed an evidence-based diagnostic algorithm to guide clinicians in characterising these lesions. Simple cysts are the most common cystic liver disease, and diagnosis is based on typical USG characteristics. Serodiagnostic tests and microbubble contrast-enhanced ultrasound (CEUS) are invaluable in differentiating complicated cysts, echinococcosis and cystadenoma/cystadenocarcinoma when USG, CT and MRI show ambiguous findings. Therefore, serodiagnostic tests and CEUS reduce the need for invasive procedures. Polycystic liver disease (PLD) is arbitrarily defined as the presence of > 20 liver cysts and can present as two distinct genetic disorders: autosomal dominant polycystic kidney disease (ADPKD) and autosomal dominant polycystic liver disease (PCLD). Although genetic testing for ADPKD and PCLD is possible, it is rarely performed because it does not affect the therapeutic management of PLD. USG screening of the liver and both kidneys combined with extensive family history taking are the cornerstone of diagnostic decision making in PLD. In conclusion, an amalgamation of these recent advances results in a diagnostic algorithm that facilitates evidence-based clinical decision making.展开更多

METHODS: A total of 100 cases of patients with cerebral stroke complicated with hemiplegia who were admitted to Rehabilitation Medicine Department of Suzhou Municipal Hospital from May 2016 to May 2017 were selected and randomly divided into study group(50 cases) and control group(50 cases), and they were nursed for 1 month. Control group was given routine nursing, and study group was given progressive muscle relaxation training combined with TCM emotion nursing on the basis of routine nursing. The scores of all items were obtained by nurses through questionnaires, and the motor function and quality of life were analyzed and compared between the 2 groups. RESULTS: After nursing, the scores of muscle strength, Barthel index(BI) and Fugl-Meyer motor function scales in study group were higher than those in control group(P < 0.05). The facing scores of coping style in study group were higher than those in control group, and the avoidance score and yielding score were lower than those in control group(P < 0.05). The scores of depression and anxiety in study group were lower than those in control group(P < 0.05). The scores of items in SF-36 life scale in study group were higher than those in control group(P < 0.05). CONCLUSION: Progressive muscle relaxation training combined with TCM emotion nursing is conducive to the recovery of motor function and improvement of quality of life in patients with cerebral stroke complicated with hemiplegia.展开更多

Therefore, we aimed to study the effects of different cataract surgery techniques on endothelial cell loss in transplanted corneal grafts. Methods： A total of 54 patients who received complicated cataract surgery in post-penetrating keratoplasty （PKP） eyes at the Shandong Eye Institute between February 2001 and June 2014 were included, and clinical records were reviewed. Baseline demographic details, clinical characteristics, endothelial cell density （ECD）, and best-corrected visual acuity （BCVA） were recorded. Wilcoxon rank-sum test and Wilcoxon signed-rank test were used to test the equality of medians. A regression model was constructed to compare the reduced rate of ECD. Results： Of the 54 eyes included in this study, extracapsular cataract extraction （ECCE） was performed in 34 eyes of 33 patients （ECCE group） whereas phacoemulsification was performed in 20 eyes of 20 patients （phacoemulsification group）. There was no signifcant difference in the median age （P = 0.081） or preoperative ECD （P = 0.585） between the two groups. At 6 months after cataract surgery, ECD in ECCE group was significantly higher than that in phacoemulsification group （P = 0.043）. In addition, the endothelial cell loss rate in ECCE group was significantly lower than that in phacoemulsification group at 2 months （P = 0.018）, 4 months （P 〈 0.001）, and 6 months （P 〈 0.001） after cataract surgery. Endothelial cell loss rate after cataract surgery increased over the 6-month study duration in both ECCE group （P 〈 0.001） and phacoemulsification group （P 〈 0.001）, but phacoemulsification resulted in a greater reduction in ECD than that of ECCE in transplanted corneal grafts （P 〈 0.001）. There was no signifcant difference in postoperative BCVA between the two groups （P = 0.065）. Conclusion： ECCE is more suitable than phacoemulsification in cataract surg展开更多

In this method the three-dimensional hydroelasticity theory of floating bodies is combined with the shallow water wave theory, to allow for proper description of the influence of uneven seabed and sheltering effect of islands on the hydroelastic responses of a VLFS deployed near island and reefs in shallow sea. This method and the numerical procedures were verified and validated by comparison-between the predictions and the model test results of a 3-module VLFS and an 8-module VLFS in two simulated shallow sea regions with different seabed topography.展开更多
