Carcinoids of the pancreas are exceedingly rare tumors that originate from the enterochromaffin cells of the gastroenteropancreatic neuroendocrine system. According to a recent report, pancreatic carcinoids are found in only 0.58% （79/13 715 cases） of the entire carcinoid group. To date, very limited information regarding the detection and diagnosis of this entity has been reported in the available literature. Although pancreatic carcinoid tumors grow slowly and show an indolent clinical behavior, they are potentially malignant. Due to the late onset of clinical symptoms and delayed diagnosis of the tumor, there was a high incidence of distant metastases that hampered long-term survival for many patients, leading to an unfavorable overall prognosis.

[Objective] More accurate, rapid and sensitive method of melamine and cyanuricacid residue in dairy products and feedstuff were re- viewed. [ Method] Physicochemical properties, metabolism, uses, harm and detection methods of melamine and cyanuric acid were analyzed and described. [ Result] Melamine and cyanuric acid, when used alone, were slightly toxic, but long -term intake could lead to animal reproductive and urinary system damage. [ Condusion] Establishing a more sensitive, fast and easy to popularize detection method for elarnine and cyanuricacid res- idue in dairy products and feedstuff was necessary.

采用催化化学气相法在炭纤维表面原位生长纳米炭纤维后,再通过化学气相渗透法制备出纳米炭纤维改性C/C复合材料。采用微动摩擦磨损试验考察纳米炭纤维改性C/C复合材料的摩擦磨损性能,探讨原位生长纳米炭纤维对C/C复合材料摩擦磨损机理。结果表明,采用纳米炭纤维改性后C/C复合材料的摩擦过程更平稳,磨损量减小。纳米炭纤维与热解炭形成复合基体,这种复合基体在摩擦过程中形成高强度高模量的摩擦膜,从而影响复合材料的摩擦性能。

为探索建成环境对行人交通事故的影响并为行人事故预防提供理论依据,本文以建成环境“5D”要素为基础,围绕土地利用、城市设计和交通系统这3个维度构建昼夜建成环境指标体系,基于轻度梯度提升机构建昼-夜间行人交通事故严重程度模型,探究城市建成环境对行人交通事故严重程度的影响机制,结合SHAP(Shapley Additive Explanation)归因分析方法揭示两者之间的非线性关系,并以深圳市为例进行实证分析。结果表明:建成环境对行人交通事故的影响效应存在显著的时段异质性;昼间行人交通事故严重程度主要受人行道可达性、地铁站可达性及学校邻近度等因素的影响;夜间行人交通事故严重程度主要受人行道可达性、娱乐兴趣点(POI)指标及道路照明条件等因素的影响。建成环境对行人交通事故严重程度存在显著的非线性影响。昼间时段学校邻近度介于[0,3]km时,地铁站可达性小于1 km时,对行人事故严重程度有较大抬升作用;夜间时段娱乐POI可达性小于0.5 km时,对行人事故严重程度有抬升作用;不论昼夜,人行道可达性对行人事故严重程度均有压降作用,且临街院门密度低的区域行人事故严重程度较高。昼-夜间模型均表现出优秀的效果,分类准确率分别为96.38%和92.08%。

Bring forward a new analytical method in order to evaluate the stability of the process of aluminum alloy pulsed MIG welding. The ratio of the first and the second peak in arc voltage signal probability density was selected to evaluate aluminum alloy pulse MIG welding stability. By calculating the arc voltage signal probability density from 80 sets of welding experiments, the ratio of the two peaks in arc voltage probability in every set was captured. And the evaluation system of aluminum alloy pulse MIG welding stability was established. The smaller the ratio of peaks in arc voltage signal probability density is, the better the stability of the welding will be;the bigger the ratio of peaks in arc voltage signal probability density is, the poorer the stability of the welding will be.

Professor QIN attaches great importance to the theory of Governor Vessel and focuses on the regulation of the yang qi in the Governor Vessel. In the early 1960s, he put forward the viewpoint that the Gov ernor Vessel is mainly used to treat such diseases of the limbs as cervical and lumbar retrograde affection,apoplectic sequelae and syringomyelia. In Chinese medicine, the Governor Vessel is considered as the sea and commander of yang meridians, dominating the yang qi throughout the body and connecting the hand and foot yang meridians. Professor QIN applies the theory of Governor Vessel to harmonize yin and yang, qi and blood, ultimately to treat various miscellaneous disorders. Gradually, he gets used to use the Governor Vessel to treat miscellaneous diseases. Clin ical practice has proved that the acupoints of the Governor Vessel have better effects than the local acupoints in the treatment of miscellaneous *** clinical experience is presented as follows.

AIM：To investigate the effects of dexamethasone（DEX） and 1-（5-isoquinolinesulfonyl）-homopiperazine（HA1077） on actin cytoskeleton and β-catenin in cultured human trabecular meshwork（HTM） ***： The HTM cells were separated from human eyeball and cultured in *** were divided into control group,DEX（1×10^-6mol/L） group,HA1077（3×10^-5mol/L）group,and DEX（1×10^-6mol/L） and HA1077（3×10^-5mol/L）*** cytoskeleton and β-catenin in HTM cells of the four groups were examined by immunofluorescence and Western blot ***： In DEX group,there were reorganization of actin cytoskeleton and formation of cross linked actin networks（CLANs）,which were partially reversed in DEX and HA1077 *** treatment also induced an increased expression of β-catenin,which was obviously reduced in DEX and HA1077 ***,the cultured HTM cells in HA1077 group had lower expression of β-catenin than that in the control group. CONCLUSION： Our results show that HA1077 can reverse the changes of actin organization and expression of β-catenin induced by DEX in cultured HTM cells,suggesting that HA1077 may play an important role in increasing outflow and reducing intraocular pressure.
