[Objective] To detect and genotype HPV in cutaneous wart tissue.[Methods] This study recruited 132 outpatients with cutaneous warts in the Affiliated Hospital of Zunyi Medical College.Of the 132outpatients,46 had verruca vulgaris,38 had verruca plantaris,and 48 had verruca plana.Ten healthy human and 15 patients with condyloma acuminatum served as the control.Tissue specimens were obtained from the lesions of these patients as well as from the normal skin of the healthy controls.DNA was extracted from the specimens followed by PCR amplification with general and type-specific primers.[Results] Of the 132 wart specimens,128 (97.0％) were positive for HPV,111 (84.1％) for HPV2,89 (67.4％) for multiple types of HPV,55 (41.7％) for two types of HPV,28 (21.2％) for three types of HPV,and 6 (4.6％) for four types of HPV.The most prevalent HPV types were HPV2 followed by HPV1 in verruca vulgaris and verruca plantaris,HPV2 followed by HPV10,HPV3 and HPVl in verruca plana.Multiple types of HPV were identified in 50.0％(23/46) of the verruca vulgaris specimens,76.3％ (29/38) of the verruca plantaris specimens,and 77.1％(37/48) of the verruea plana specimens.Among patients infected with more than one type of HPV,the combination of HPV1 and 2 was the most common (35,39.3％),followed the combination of HPV1,2 and 10(12,13.5％).[Conclusion]s The most prevalent HPV type appears to be HPV2,followed by HPV1,in patients with cutaneous warts in Zunyi area of Guizhou province.HPV2 infection is associated with various types of cutaneous warts.There is a high incidence of coinfection with multiple types of HPV in patients with cutaneous warts,especially in those with verruca plana.Moreover,HPV3 and 10 are newly identified in verruca vulgaris,HPV 10 in verruca plantaris,HPV 1 and HPV7 in veruca plana.

IgA nephropathy (IgAN) is one of the common primary glomerulonephritis, which is also an important risk factor for end-stage renal disease. Kidney transplantation is the optimal treatment for end-stage renal disease induced by IgAN, whereas there is still a risk of recurrence of IgAN after kidney transplantation. At present, research progress upon IgAN recurrence after kidney transplantation is relatively lacking. The pathogenesis of IgAN recurrence remains elusive, and its pathological manifestations are not specific. The diagnosis of IgAN recurrence still depends on renal biopsy. Besides, no effective prevention and treatment are available for recurrent IgAN. In this article, research progress on IgAN recurrence after kidney transplantation was illustrated from the perspectives of pathogenesis, diagnosis, risk factors and treatment, aiming to provide reference for clinical prevention and treatment of IgAN recurrence after kidney transplantation and improve clinical prognosis of kidney transplant recipients.

（正）结肠代食管术（esophageal replacement with colon，ERC）被称作食管外科“皇冠上的明珠”，也是食管重建的最后一种选择。ERC 手术操作复杂，吻合口瘘等并发症发生率较高，一直没有得到广泛开展[1]。传统 ERC 手术常选择经右侧胸腹联合切口，手术创伤较大、术后恢复慢、术后肋间神经损伤等并发症较多，但随着胸腔镜微创技术的日益发展，我们使用胸腔镜微创技术游离胸腔食管并清扫纵隔淋巴结，开腹横结肠代食管行消化道重建，该技术可减少手术创伤、减轻术后疼痛，加速康复。本视频在于展示胸腔镜辅助食管癌根治横结肠代食管术手术入路、操作技巧。

Objective: To explore the value and disadvantage of micro-mirror in the intracranial aneurysm surgery. Methods: Micro-mirror was used to assist microsurgical clipping to 36 intracranial aneurysms in 31 cases, of which 3 were carotid-ophthalmic artery aneurysms, 3 anterior choroidal artery aneurysm, 11 were posterior communicating artery aneurysms, 7 were middle cerebral artery aneurysms, 10 anterior communicating artery or anterior cerebral artery aneurysms, and the others were a posterior cerebral artery aneurysm and a posterior inferior cerebellar artery aneurysm. The micro-mirror was used before and after clipping to observe the anatomic features of necks hidden behind and medial to aneurysms, to visualize surrounding neurovascular structures, and to verify the optimal clipping position. Intraoperative indocyanine green fluorescein angiography confirmed the success of sufficient clipping. Results: All aneurysms were clipped successfully. The parent arteries were occluded temporarily in 26 cases, and 9 aneurysms ruptured during the operation. Postoperative follow-up lasted from 2 weeks to 1 year. After operations digital subtraction angiography (DSA) were repeated in 10 cases, computed tomography angiography(CTA) in 21 cases, and no insufficient clipping or occlusion of parent arteries were revealed. Conclusions Micro-mirror assisting microsurgical clipping to the intracranial aneurysm is conducive to accurate clipping, and is a convenient and practical operation.
