The crystalline structures and crystallization behaviors of iPP containing β nucleation agent TMB-5 （iPP/TMB-5） were investigated by synchrotron radiation wide angel X-ray diffraction （SR-WAXD）, differential scanning calorimeter （DSC） and polarized light microscope （PLM）. It was found that α-crystallization lagged behind β-crystallization at normal temperatures, but the discrepancy reduced with increasing temperature. TMB-5 could not induce β-iPP when the nucleation agent is wrapped up with α-crystal that crystallized at high temperatures. The polymorphic composition of iPP/TMB-5 was susceptible to the introductory moment of shear. New crystallization process of β-nucleated iPP was proposed to understand the experimental phenomena which could not be explained by those reported in the literature. It was supposed that polymer crystallization initiated from mesophase, and the formations of iPP crystals involved the organization of helical conformation ordering within rnesophase. It was proposed that the iPP melt contained mesophases with stereocomplex-type ordering of right-handed and left-handed helical chains which could be disturbed by shear or TMB-5, leading to different polymorphic structures.

The infratemporal fossa approach was designed for the removal of large tumors located at the temporal bone and lateral skull base.[1]This approach has several subtypes,including types A,B,C,and *** infratemporal fossa type B(ITFB)approach exposes the petrous apex,clivus,and horizontal segment of the internal carotid artery(ICA)and is used to remove tumors in this area.[2]The classical ITFB approach to fully exposing the horizontal segment of the ICA includes subtotal resection of the petrous bone,removal of the anterior wall of the external auditory canal and zygomatic arch,resection of the articular disc and condylar process of the mandible,downward traction of the mandible,and transection of the mandibular branch of the trigeminal nerve and middle meningeal artery.

Land use changes are regarded as landscape pattern change driven by many interactive natural and social-economic factors. Different combination of physical geographical elements induced the difference of spatio-temporal pattern of land use change. There are four physical geographical regions in Mongolian Autonomou County of Qian Gorlos of Jilin Province. Based on spatial analysis and statistical analysis, we conclude that the primary pattern of land use and the tendency of land use changes are all different in four physical geographical regions. During 1987 – 1996, the dominant land use change processes were from grassland or forest to arableland, from unused land to paddy and grassland to unused land. Though land use change is mainly affected by social and economic condition in short period, the composite characters of physical geographical elements controls land use dynamic process. The relationship between land use dynamic process and the character of physical geographical units differ in different regions. Possible human impacts on land use change are explored with application of buffer areas of series distance along main roads and radius around main settlements. A few models are built to describe the relationship between land use spatial change rates and distance to road and settlements. According to our result, the relationship with the proximity to roads was a negative liner function, with the change rate decreasing rapidly when moving away from roads. Within a distance of less 7.5km from main traffic lines, land use changes occur red more. The bulk of grassland was apt to be opened up for cultivation around the settlements and the transformation from dryland to paddy occurred within the distance of 1km away from settlements.

多房性前列腺囊腺瘤（multilocular prostatic cystadenoma,MPC）是一种罕见的前列腺组织来源的良性肿瘤,肿瘤体积通常较大,位于直肠和膀胱之间[1]。患者主要表现为泌尿系梗阻症状,如排尿中断、尿流较细、尿不尽等。影像学检查如前列腺超声、盆腔磁共振成像不仅可以提供肿瘤的位置信息,以及与周围器官的关系,还有助于与其他恶性肿瘤鉴别。由于MPC罕见且缺乏长期的随访报告,该病的诊断和治疗尚无定论。2017年8月北京大学人民医院泌尿外科收治MPC经尿道电切术后复发1例,并成功行经尿道前列腺电切术（transurethral resection of prostate,TURP）,现报告如下。
