The gradient based landscape metrics analysis is now widely used to study the landscape pattern changes in respond to the *** order to discover the trend of spatio-temporal changes in Beijing metropolitan area during the past 15 years,several landscape metrics are computed using a moving window along a 96 km long transect across Beijing metropolitan area from west to ***,the spatial extent of sub-landscape,which is determined by the moving window’s size,is profoundly *** results show that the metrics varies smoothly and regularly along the selected transect when the window size is greater than 6 km×6 km,and irregularly fluctuated for the smaller window size,that the spatial and temporal landscape characteristics of Beijing city match the hypothetical framework of spatio-temporal urban sprawl in the form of alternating processes of diffusion and coalescence well,and that some new trends of the urban sprawl style in Beijing metropolitan area,such as leap-frog manner,are also detected by the gradient landscape analysis.

Carbon isotope ratios (δ^(13)C) of 89 C_4 plant samples were determined fromthe loess area in North china. δ^(13)C values vary between -10.5per thousand and -14.6per thousandwith a mean of -12.6per thousand. Along a precipitation gradient from the semi-moist area to thesemiarid area, then to the arid area, the δ^(13)C values of C_4 plants show a slight decreasingtrend. The δ^(13)C values of C_4 plants in the dry season are found lower than those in the wetseason. These trends are opposite to those observed for C_3 species.

A segment of Mesozoic subduction-accretion zone was inferred across thenortheastern South china Sea at approximately NE450 orientation. Basic evidence includes thefollowing: A belt of peek gross horizontal Bouguer gravity gradient (PGHGBA) is comparable in sizeand intensity to that of the Manila subduction-accretion zone. A belt of high positive magneticanomalies appears to the north and sub-parallel to the PGHGBA, representing the volcanic arcassociated to the subduction zone. The PGHGBA crosses obliquely both Cenozoic structures and presentseafloor topography, indicating a pre-Cenozoic age. The segment is offset left-laterally byNW-running strike-slip faults, in concord with the Mesozoic stress field of South china. Inaddition, the existence of the subduction zone is supported by wide-angle seismic data obtained indifferent years by different institutions. At approximate localities, a north-dipping ramp of Mohosurface is indicated by records of ocean-bottom seismometers, and a strong reflector about 8 kmbeneath the Moho reflector is indicated by both OBS and long-cable seismic records. Theidentification of a segment of Mesozoic subduction zone in NE South china Sea fills nicely the gapof the Great Late Mesozoic Circum SE Asia Subduction-acrretion Zone, which extended from Sumatra,Java, SE Kalimantan to N Palawan, and from Taiwan, Ryukyu to SW Japan.

Groundwater is the main source of drinking water for the urban and rural residents in the plain area of the Xinjiang Uygur Autonomous Region,*** quality of groundwater has a direct relationship with human ***,386 groundwater samples collected from April to August in 2003 were analyzed The samples were collected in basic evaluation units which are determined on the basis of *** dissolved solids,total hardness,pH ***-N,CHOH, Chemiluminescence detection of permanganate index (COD)and intestinal germ group were evaluated according to the guidelines of Groundwater Quality Standard(GB/T14848-93).The quality of the groundwater in each evaluation unit was classified by using the One Veto Method(a unified approach stipulated by the Ministry of Water Resources).The results indicate that the groundwater in the mainstream area of the Tarim Basin and the Yerqiang River Sub-basin belongs to Category V;the groundwater in the Wulungu River Sub-basin,the Kaidu-Kongque River Sub-basin,the Kashgar River Sub-basin, the Cherchen River Sub-basin and the Hotan River Subbasin belongs to CategoryⅣ;the groundwater in the Aibi Lake System belongs to CategoryⅡ,and the groundwater of other evaluation units belongs to CategoryⅢ.The causes of water quality formation were concisely analyzed. The results can be useful for the evaluation and management of water resources in the Xinjiang Plain Area.

目的探讨改良尿道分离方式在压力性尿失禁(SUI)患者人工尿道括约肌(AUS)植入术中的应用情况,及其对尿道压力描记检查结果的影响。方法前瞻性收集2019年3月至2023年6月在北京医院、首都医科大学附属北京积水潭医院和天津医科大学第二医院接受改良尿道分离方式AUS植入术并完成尿道压力描记检查的25例SUI患者的临床资料,改良尿道分离方式为在游离尿道海绵体背侧时,借用部分海绵体白膜组织。记录尿道周径、袖套尺寸及尿道压力情况,比较手术前后患者的自主控尿情况以及国际尿失禁咨询委员会尿失禁问卷表简表(ICI-Q-SF)评分、尿失禁生活质量问卷(I-QoL)评分、尿频评分及夜尿评分的变化情况。激活装置后的第1、3、6、12个月时于门诊或电话进行随访,之后每年进行1次随访。评估局部皮肤状态、控尿情况,测量残余尿量超声并完成主观评分量表测定。结果患者均为男性,年龄27~85岁(65.8±15.7)岁。选用4.0 cm袖套4例(16.0%),4.5 cm袖套16例(64.0%),5.0 cm袖套4例(16.0%),5.5 cm袖套1例(4.0%);其中尿道周径与袖套尺寸完全匹配14例(56.0%),尿道周径小于袖套尺寸4例(16.0%),尿道周径大于袖套尺寸7例(28.0%)。25例患者术前最大尿道压力(MUP)为(78.0±25.9)cmH_(2)O(1 cmH_(2)O=0.098 kPa),最大尿道闭合压力(MUCP)为(53.4±26.6)cmH_(2)O。采用AUS装置在术中失活状态下MUP为(88.0±26.5)cmH_(2)O,与术前差异无统计学意义(P>0.05);MUCP为(68.2±24.5)cmH_(2)O,高于术前(P146.6±25.2)cmH_(2)O,MUCP为(123.0±28.3)cmH_(2)O,均高于术前及失活状态下(均P1)。全组患者在装置激活的第1个月时,均达到社交控尿标准。全组患者随访2~50个月,随访过程中,22例(88.0%)患者达到社交控尿标准,1例患者更换AUS装置,1例患者因脑血管意外死亡,1例患者因并发症取出装置。25例患者术前和术后分别使用尿垫[M(Q_(1),Q_(3))]4.5(3.0,6.5)个和1(0,1)个,差异有统计学意义(P1)。25例患者术后的ICI-Q-SF评分、I-QoL评分、尿频评分和夜尿评分均较术前明显改善(均P20.0%)患者出现术后并发症,其中无痛性血尿2例,感染1例,尿道侵蚀1例,排尿困难1例。除出现尿道侵蚀的1例患者移除袖套外,其余4例患者在积极支持治疗下均恢复社交控尿,且至末次随访症状均未复发。结论改良尿道分离方式未明显影响SUI患者尿道压力,且可增加袖套内尿道周围组织体积,从而降低术中尿道损伤风险及术后尿道侵蚀的发生率。
