分析超声与超声弹性成像(UE)在诊断老年乳腺良恶性病变上的应用价值。回顾性分析聊城市第二人民医院2020年5月—2022年5月收治的老年乳腺占位113例患者的临床资料,全部患者均接受了乳腺超声联合UE与常规超声两种检查,通过穿刺活检或手术获得病灶组织进行病理检查,对比这两种检查方法检出的肿瘤最大直径、老年乳腺癌检出率及诊断准确率。病理学检查结果显示,在113个病灶当中,良性病变68个,恶性病变45个。乳腺良性病变组与恶性病变组相比,病灶形态规则、无回声、边界清晰、0级与1级血流信号等超声特征所占比例较高,差异有统计学意义(P<0.05);恶性病变组与良性病变组相比,弹性模量均值、弹性模量最大值、弹性模量最小值均较高,差异有统计学意义(P<0.05)。超声联合UE对不同象限肿瘤病灶的检出合计率高于常规超声,差异有统计学意义(P<0.05)。超声联合UE的诊断准确率要高于常规超声,差异有统计学意义(P<0.05)。超声特征与UE参数被认为是判断乳腺良恶性病灶的一种可靠的方法,两者联合应用诊断鉴别乳腺良恶性的价值要明显高于常规超声。

AIM: To evaluate the effectiveness and safety of early nasogastric enteral nutrition (NGEN) for patients with severe acute pancreatitis (SAP). METHODS: We searched Cochrane Central Register of Controlled Trials (Issue 2, 2006), Pub-Medline (1966-2006), and references from relevant articles. We included randomized controlled trials (RCTs) only, which reported the mortality of SAP patients at least. Two reviewers assessed the quality of each trial and collected data independently. The Cochrane Collaboration’s RevMan 4.2.9 software was used for statistical analysis. RESULTS: Three RCTs were included, involving 131 patients. The baselines of each trial were comparable. Meta-analysis showed no significant differences in mortality rate of SAP patients between nasogastric and conventional routes (RR = 0.76, 95% CI = 0.37 and 1.55, P = 0.45), and in other outcomes, including time of hospital stay (weighted mean difference = -5.87, 95% CI = -20.58 and 8.84, P = 0.43), complication rate of infection (RR = 1.41, 95% CI = 0.62 and 3.23, P = 0.41) or multiple organ defi ciency syndrome (RR = 0.97, 95% CI = 0.27 and 3.47, P = 0.97), rate of admission to ICU (RR = 1.00, 95% CI = 0.48 and 2.09, P = 0.99) or conversion to surgery (RR = 0.66, 95% CI = 0.12 and 3.69, P = 0.64), as well as recurrence of re-feeding pain and adverse events associated with nutrition. CONCLUSION: Early NGEN is a breakthrough in the management of SAP. Based on current studies, early NGEN appears effective and safe. Since the available evidence is poor in quantity, it is hard to make an accurate evaluation of the role of early NGEN in *** recommendation to clinical practice, further high qualified, large scale, randomized controlled trials are needed.

在国内应用圆锥型套筒冠义齿对各类病例进行修复治疗已达 15 年,临床取得了良好的远期效果.由于圆锥型套筒冠义齿适用范围广,一般固定义齿和可摘局部义齿的适用范围均可作为其适应证.尽管如此,目前临床医师对如何正确掌握其适用范围仍存在一些问题.特别是此类义齿制作工艺要求较高,费用较高,在选择该修复方法之前,医师应根据缺牙区情况,基牙牙周组织健康状况,患者对修复的具体要求,患者的经济承受能力等,综合分析,充分估计其远期疗效再作决定。

indica and japonica are the two most important subspecies of Asian cultivated rice. Identifying mechanisms responsible for population differentiation in these subspecies is important for indica-japonica hybridization breeding. In this study, subspecies and economic trait differentiation patterns were analyzed using morphological and molecular （InDel and Intron Length Polymorphism） data in F2 and F3 populations derived from indica-japonica hybridization. Populations were grown in Liaoning and Guangdong provinces, China, with F3 populations generated from F2 populations using bulk harvesting （BM） and single-seed descent methods （SSD）. Segregation distortion was detected in F3-BM populations, but not in F3- SSD or in F2 populations. Superior performance was observed with respect to economic traits in Liaoning compared with that in Guangdong and 1 000-grain weight （KW）, seed setting rate （SSR） and grain yield per plant （GYP） were significantly correlated with indica and japonica subspecies types. Analysis of molecular and morphological data demonstrated that the environment is the main factor giving rise to population differentiation in indica-japonica hybridization. In addition, we also found that KW, SSR and GYP are related to subspecies characteristics and kinship, which is possibly a significant factor resulting in economic trait differentiation and determining environmental adaptability. Our study has provided new insights into the process of population differentiation in these subspecies to inform indica-japonica hybridization breeding.

AIM： To determine the most cost-effective hemofiltration modality for early management of severe acute pancreatitis （SAP） in China. METHODS： We carried out a search of Pub-Medline and Chinese Biomedical Disk database. Controlled clinical trials on Chinese population were included in the analysis. The four decision branches that were analyzed were： continuous or long-term veno-venous hemofiltration （CVVH/LVVH）, short-term veno-venous hemofiltration （SVVH）, SVVH plus peritoneal dialysis （PD）, and non-hemofiltration control group. The effectiveness of the technique was determined by survival rate, complications prevention and surgery preservation. The total cost of hospitalization was also assessed. RESULTS： The SVVH only technique was the least costly modality, $5809 （44449 RMB）, and was selected as the baseline treatment modality. SVVH only arm achieved the lowest C/E ratio in terms of overall survival, complications prevention and surgery preservation. In incremental cost-effectiveness analysis, the CWH/ LVVH only and the control arms were inferior to other techniques. Sensitivity analysis showed SVVH only and SVVH plus PD arms overlapped in C/survival ratio. CONCLUSION： The role of early veno-venous hemofiltration as an alternative therapy for SAP remains controversial. However, we propose that early use of short-term high-volume veno-venous hemofiltration would have a beneficial impact on the management of SAP.
