The southern coast of Laizhou Bay, Bohai Sea, is one of the areas in China most seriously impacted by seawater intrusion. Based on the sources of intruding waterbodies, seawater intrusion can be divided into two types: intrusion of saline water derived from modern seawater, and intrusion of subsurface brine and saline water derived from paleo seawater in shallow Quaternary sediments. There are some distinct differences in their formation, mechanism and damage. The subsurface brine intrusion is a special type, which can cause very serious disaster. The coastal landform and the Quaternary hydrogeological environment are predominant factors in the classification of seawater intrusion types. Various coastal environments in different coastal sections result in three types of intrusion: seawater intrusion, saline groundwater intrusion, and mixed seawater and saline water intrusion, in the southern coast of Laizhou Bay, which can be divided into four areas: the seawater intrusion area in the northern Laizhou City coast, the mixed seawater and saline groundwater intrusion area in the Baisha River Jiaolai River mouth plain area, the mixed seawater and saline groundwater intrusion area in the Weihe River mouth plain area northern Changyi county coast, and the saline groundwater intrusion area in the northern Shouguang plains.

目的探讨经直肠超声引导前列腺穿刺活检的临床应用价值。方法 2011年1月至2012年1月,我科60例选患者在无麻醉情况下,采用经直肠超声引导10点前列腺穿刺活检,取出前列腺组织送病理检查。结果 60例患者中,前列腺癌检出率为53.3%。前列腺特异性抗原(PSA)水平的不同,前列腺结节超声显示率差异具有统计学意义(P=0.0246),前列腺结节显示率随PSA水平的增加而增加(P=0.0014);不同PSA水平组的病理结果差异具有统计学意义(P<0.0001),穿刺阳性率随PSA水平升高而逐渐上升。结论超声结节检出率会随着PSA水平升高而增大,前列腺癌的检出率均与PSA水平呈正相关。经直肠引导前列腺穿刺法阳性率较高,安全性好,具有很高的临床推广价值。

Based on the authors’1986 to 1994 sporo-pollen assemblage analysis in the southern Yellow Sea area, data from 3 main cores were studied in combination with 14C, palaeomagnetic and thermoluminescence data. The evolution of the paleoclimate environments in the southern Yellow Sea since 15ka B.P. was revealed that, in deglaciation of the last glacial period, the climate of late glaciation transformed into that of postglaciation, accompanied by a series of violent climate fluctuations. These evolution events happened in a global climate background and related to the geographic changes in eastern China. We distinguished three short-term cooling events and two warming events. Among them, the sporo-pollen assemblage of subzone A 1 showed some cold climate features indicating that a cooling event occurred at about 15-14ka. B.P. in early deglaciation. This subzone corresponds to the Oldest Dryas. In subzone A 3, many drought-enduring herbal pollens and some few pollens of cold-resistant Picea, Abies, etc. were found, which indicated that a cooling event, with cold and arid climate, occurred at about 12-11ka. B.P. in late deglaciation. This subzone corresponds to the Younger Dryas. The sporo-pollen assemblage of zone B showed warm and arid climate features in postglaciation. Although the assemblage of subzone B 2 indicated a cold and arid climate environment, the development of flora in subzone B 2 climate was less cold than that in A 3. Subzone B 2 indicated a cooling event which occurred at about 9ka B.P. in early Holocene. Subzone A 2, with some distinct differences from subzone A 1 and A 3, indicated a warming event which occurred at 14-13ka. B.P. and should correspond to a warming fluctuation. The sporo-pollen assemblage of zone C showed features of warm-moist flora and climate, and indicated a warming event which universally occurred along the coast of eastern China at 8-3ka B.P. in middle Holocene, and its duration was longer than that of any climate events mentioned a

目的研究丹红注射液及其单体成分对小鼠小胶质细胞株(BV-2细胞)的影响及其作用机制。方法实验分为对照组、脂多糖(LPS)刺激组、加药组,检测不同稀释倍数的丹红注射液、水和醋酸乙酯萃取物及其单体成分对小胶质细胞活力及LPS诱导小胶质细胞一氧化氮(NO)产生的影响。结果丹红注射液及醋酸乙酯萃取物对LPS诱导的小胶质细胞NO的产生没有抑制作用,但是丹红注射液水萃取物以及丹酚酸A可以在不影响细胞活力的情况下抑制NO产生。结论丹红注射液水萃取物中的某些成分以及丹酚酸A抑制激活小胶质细胞NO的产生可能是丹红注射液神经保护作用的机制之一。

本文对159例在PTC和B超检查后进行了手术的肝胆胰患者进行分析后,认为PTC对胆道结石、胆道肿瘤、壶腹癌、胰头癌、胆道狭窄和先天性胆道异常等疾病的诊断价值高于B超,因其除确诊率较高外,还可直接显示病变的部位和范围,有利于手术方案的制定。而B超对胆囊结石的诊断率远远高于PTC。作者建议对肝胆胰疾病可先做B超检查,诊断不明再行PTC或其他检查。
