AIM: To review the experience in the management of impalpable testes using laparoscopy as the initial approach and the need for inguinal ***: From January 2004 to June 2014, 339 patients with undescended testes underwent operation in our institute. Fifty patients(15%) had impalpable testes. All children with impalpable testes underwent initial laparoscopy. A retrospective review was conducted on this group of patients and the outcome was ***: Forty children had unilateral impalpable testis. Ten children had bilateral impalpable testes. Thirty-one children(78%) in the unilateral group underwent subsequent inguinal exploration while 4 children(40%) in the bilateral group underwent inguinal exploration(P < 0.05). Orchidopexy was performed in 16 children(40%) in the unilateral group and 9 children(90%) in the bilateral group(P < 0.05). Regarding the 24 children with unilateral impalpable testis and underwent orchidectomy for testicular nubbin(n = 19) or atrophic testes(n = 2) or has vanishing testes(n = 3); contralateral testicular hypertrophy was noticed in 10(41%). No intra-operative complication was encountered. Two children after staged Fowler-Stephensprocedure and 1 child after inguinal orchidopexy had atrophic ***: The use of laparoscopy in children with impalpable testes is a safe procedure and can guide the need for subsequent inguinal exploration. Children with unilateral impalpable testis were associated with an increased need for inguinal exploration after laparoscopy. Orchidopexies could be performed successfully in 90% of children with bilateral impalpable testes.

岩土工程中的岩体常处于空间应力状态,因此,研究空间应力状态下岩石的损伤破坏机理有着重要的实际工程意义。基于岩石内部缺陷分布的随机性,建立了围压和轴压共同作用下岩石的统计损伤本构模型。并通过砂岩的三轴压缩试验确定了模型里的参数,定性分析了围压对损伤度的影响。研究结果表明:1)模型能反映围压效应,即可以体现岩石强度随围压变化的规律;并且模型参数确定方法揭示了模型参数的物理意义;2)通过岩石的应力-应变全曲线特征及峰值应力与应变确定模型参数,不同的围压对应着不同的参数;3)临界损伤度与岩石所处的应力状态有关,同一种岩石在不同围压下临界损伤度是变化的;4)由分布参数m的物理含义可知,m可以做为表征砂岩脆性的参数;1/m可以做为表征砂岩延性的参数。

AIM： To investigate the prevalence and clinical pattern of gastrointestinal stromal tumors （GISTs） in Hong Kong Chinese, and to assess the impact of introduction of CD117 on the disease incidence. METHODS： From the database of the Department of Pathology of yan Chai Hospital, 47 patients, with GISTs from September 1995 to December 2003 were included in this study. Ten GISTs were diagnosed before the introduction of CD117. The clinical features, tumor characteristics, and treatment were analyzed. Factors predicting tumor related death or recurrence were studied with Cox proportional hazard model. RESULTS： The patients included 26 males and 21 females, with a mean age of 66.6 years （SD 13.1, range 29-87 years）. The estimated prevalence of GISTs was 13.4-15.6 per 100 000 people, with an annual inddence of 1.68-1.96 per 100 000 people. The annual incidence of GISTs before and after the introduction of CD117 was 1.1 per 100 000 people and 2.1 per 100 000 people respectively. Stomach （34 patients, 72.3%） was the most common location for the tumor, followed by the small intestine （8 patients, 17.0%）, esophagus （2 patients, 4.3%）, omentum （2 patients, 4.3%） and colon （1 patient, 2.1%）. Thirty-one patients （66%） had complete tumor resection. Eleven out of 16 deaths （23%） were tumor-related. The median survival time was 26 too. Five-year survival rate was 61.3%. The significant factors associated with tumor-related death or recurrence were incomplete resection, tumor size 5 cm or above, invasion to the adjacent organ or presence of metastasis, CONCLUSION： The incidence of GIST in Hong Kong is comparable to that in the United States but lower than that in Finland. The true incidence of GISTs could be underestimated before the introduction of CD117. Incomplete resection, tumor size 5 cm or above, invasion to the adjacent organ or presence of metastasis are factors predicting tumor-related death or recurrence.

采用高温固相法制备了Ln(Ln=Y,Gd)VO4掺Er3+或Nd3+的近红外发光材料。通过X射线粉末衍射(XRD)和光致发光(PL)对样品进行了表征。结果表明:所得产品结晶良好,属于四方晶系,锆石结构。研究了Er3+,Nd3+的含量、煅烧时间、煅烧温度等对材料近红外发光性质的影响。在Ln(Ln=Y/Gd)VO4:Er3+/Nd3+中,存在明显的从VO43-向Er3+/Nd3+的能量传递。两种不同的LnVO4(Ln=Y/Gd)基质对发光性质也有一定的影响。小浓度Bi3+的掺入可以明显提高YVO4:Er3+/Nd3+的近红外发光强度。
