The contents of both water and rock particles are important factors affecting the mechanical strength of a soil–rock mixture(SRM)filled subgrade in the western mountainous area of ***,the purpose of this paper is to study the mechanisms of reconstituted landslide deposit samples with different water and rock particle contents by analysing the characteristics of shear strength,volumetric strain and‘jumping’phenomenon via large-scale direct shear *** results show that the influence of water content on shear strength is greater than the influence of rock particle content under a lower normal stress,and the results are reversed in the case of a higher normal *** effect of water content on the equivalent cohesion is bigger,especially for the sample with a high rock particle *** friction angle of the specimen with same water content increases with the increasing rock particle content,but when the number of rock particles increases to a certain extent,there is a little effect on the friction ***,the friction angle decreases with increasing water content at the same rock particle *** with the same rock particle content change from dilation to compression with increasing water ***,the continuous stage of the‘intense jumping’at different water content has been ***‘jumping’phenomenon of samples with low water and rock particle content will first strengthen and then weaken the samples with increasing normal stress.

Objective： Lymphangioma is a benign tumor representing a congenital malformation of the lymphatic channels. The cavernous lymphangioma of the bladder did not report before. Here we report 1 case of cavernous lymphangioma of the bladder in an adult female and review the literature in order to accumulate the experience of diagnosis and treatment for these diseases. Methods： In our case a 50-year-old woman presented with irritative voiding symptoms and had painless macroscopic hematuria at times. Cystoscopy showed a non-papillary tumor at apex vesicae and mucous membrane hyperaemia between the two orifices within the trigone. The pathologic diagnosis was cystitis glandularis with hyperplasia of urothelium and cavernous lymphangioma in lamina propria. Transurethral resection was performed and then bleomycin A5 was injected into lesion multipoint applying ureteral catheter with puncture needle. Results： Two months after operation the irritative voiding symptoms improved and the urine analysis was normal. Cystoscopy showed no residual tumor. Bleomycin A5 was injected into the lesion area again just like the operation before. All symptoms disappeared completely when the patient was examined a month later. There was no side effect after injection and no recurrence during the follow-up of 1 year. Conclusion： Lymphangioma of the bladder can be diagnosed exactly by cystoscopy and pathological examination. Surgery may be the best treatment. The bleomycin A5 intralesional sclerosant is also an effective therapy for the disease after surgical removal.

目的:分析并总结肾盂瓣输尿管重建手术在输尿管上段长段狭窄中的应用经验及疗效。方法:回顾性分析2022年1月—2023年12月在华中科技大学同济医学院附属协和医院泌尿外科住院治疗的26例输尿管上段长段狭窄患者的临床资料,其中先天性肾盂输尿管连接部梗阻16例,包含肾盂输尿管成形术后再狭窄5例;输尿管镜钬激光碎石术后输尿管上段狭窄10例。术前检查提示狭窄段3~7 cm,术中采用肾盂瓣完成肾盂输尿管连接部的重建,其中腹腔镜手术6例(腹腔镜组),机器人辅助腹腔镜手术20例(机器人组)。分析2组患者的手术时间、平均出血量、平均住院日、术后肾盂前后径变化及症状改善情况。结果:所有患者均在腹腔镜或机器人辅助腹腔镜下完成,均未中转开放手术。腹腔镜组肾盂瓣输尿管成形术的平均手术时间为(131±46)min,术中平均出血量(103±66)mL,术后平均住院日(7±5)d,术后肾盂前后径缩小达95.33%,术后腹痛或腰部胀痛情况均有缓解。机器人组肾盂瓣输尿管成形术的平均手术时间为(127±24)min,术中平均出血量(48±24)mL,术后平均住院日(5.7±1.2)d,术后肾盂前后径缩小达97.00%,术后腹痛或腰部胀痛情况均有缓解。结论:肾盂瓣输尿管成形术在输尿管上段长段狭窄中取得了较好的治疗效果,操作较易掌握,且机器人辅助腹腔镜手术较腹腔镜手术具有更好的临床效果。但目前所报道的多为单一中心小样本研究,仍需更大样本量、前瞻性的研究及长期随访以进一步评估其临床有效性。

目的：荟萃分析腹腔镜下根治性膀胱切除术（laparoscopicradicalcystectomy，LRC）及开放式根治性膀胱切除术（openradicalcystectomy，ORC）治疗肌层浸润性膀胱肿瘤的疗效及安全性。方法计算机检索CochraneLibrary、PubMed、EMbase、SCI、Ovid、中国生物医学文献数据库、万方、维普和中国知网数据库，收集LRC与ORC治疗肌层浸润性膀胱癌的随机或非随机同期对照试验，检索时限截至2013年5月。由两名评价者按照纳入与排除标准选择试验、提取资料和评价质量后，采用RevMan5．2．6软件进行荟萃分析。结果纳入13个非随机对照试验，共783例患者。Meta分析结果显示：LRC较ORC术中出血量少[MD＝-466．85，95％CI（-603．33，-330．37），P＜0．001）]，输血率低[OR＝0．27，95％CI（0．18，0．41），P＜0．001]，术后住院时间短[MD＝-3．46，95％CI（-5．98，-0．94），P＝0．007]，术后恢复进食时间早[MD＝-1．16，95％CI（-1．41，-0．90），P＜0．001]，术后轻微并发症少[OR＝0．52，95％CI（0．30，0．89），P＝0．020]，手术切缘的阳性率低[OR＝0．25，95％CI（0．10，0．58），P＝0．001]，淋巴结阳性率低[OR＝0．61，95％CI（0．40，0．92），P＝0．020]，但手术时间比开放手术长[MD＝52．44，95％CI（36．67，68．21），P＜0．001]。腹腔镜手术与开放手术在淋巴结清扫数目、肿瘤局部复发及远处转移方面比较差异无统计学意义（P＞0．05）。结论在严格掌握LRC治疗肌层浸润性膀胱癌适应证的前提下，采用LRC治疗肌层浸润性膀胱癌是安全可行的。由于纳入研究数量和质量存在局限性，仍需大样本、高质量的临床对照研究进一步验证。

计算机内存取证领域中,基于内存池标记的池标记扫描技术在对内核驱动对象进行扫描时需要对全部物理内存进行详尽搜索,效率很低。提出了一种使用内存池标记快速扫描技术扫描Windows内核驱动对象的方法。该方法采用内存池标记快速扫描技术,减小扫描的内存范围,然后根据内核驱动对象特征对驱动对象进行快速扫描,以帮助调查人员判断驱动是否存在异常。实验表明,使用内存池标记快速扫描技术进行内核驱动对象扫描可以在保证误报率不变的情况下,极大地提高扫描效率,减少在扫描步骤花费的时间。

The role of interleukin-6 (IL-6) in the growth of an androgen-independent prostate cancer cell line (PC-3m) was defined and the effect of dexamethasone, which was previously shown to modulate IL-6/IL-6 receptor (IL-6R) on this procedure was investigated. By using a pretty sensitive and specific enzyme immunoassay (ELISA), it was found that PC-3m produced certain IL-6, but there was no difference in IL-6 secretion between the group with or without dexamethasone treatment. It was also found that PC-3m cells could not be stimulated to grow by exogenous IL-6 (P>0.05), while it could be inhibited to grow by anti-IL-6 monoclonal antibody and dexamethasone with a dose-dependent fashion. Our observation indicated that IL-6 acted as an autocrine growth factor for PC-3m, and dexamethasone could inhibit cell proliferation by a mechanism independent of its effect on IL-6 mRNA expression.
