Objective To investigate the causes and managements of capsular perforation in transurethral resection of prostate(TURP) for benign prostatic hyperplasia (BPH). Methods Clinical data of 893 cases who received TURP from February 2002 to February 2011 were analyzed retrospectively.Results In 893 cases, capsular perforation in 16 cases, among them, tissue covered perforation in 10 cases, dissociative perforation in 3 cases, perforation under bladder trignne in 3 cases. Six cases occurred with obviously extravasation, 10 cases with transurethral resection syndrome (TURS) or omen of TURS. Two cases were ceased operation and received TURP again after 2 weeks, 2 cases transferred to open surgery suprapubic prostatectomy, 12 cases kept up operation with lower bladder douche pressure. Two cases with postoperatire bleeding underwent open surgery hemostasis cured. All cases were discharged from hospital after recovery. Conclusions The type and extent of capsule perforation must be judged correctly,corresponding treatment must be given, prevention and treatment of TURS must be taken notice of, if capsule perforation occurs when TURP operation in progress. Less haematoma, clearview and normal anatomic structures can decrease the incidence of perforation.

With the aim of further understanding of the nerve supply of the Iumbodorsal region,and its relation to the pathogenesis of lumbago and lumbocrural pain,the superior chnial nerves of lilty adult Chinese cadavers were dissected. In the present study,it was shown that the superior clunial nerve consists of lateral branches of the posterior rami of spinal nerves rarying from T_(12)L_(1~5)and S_1 segments. The contribution of these branches to this nerve is as follows,T_(12):40 cases,L_1 and L_2: 100 cases each,L_3:96 cases,L_4:48 cases,L_5:11 cases,and S_1:4 cases.Our observation revealed the fact that the posterior rami of L_(4,s)spinal nerves consist of a lot of lateral cutaneous branches,which is not in accordance with embroyological descriptions cited in literature which deny their existence. Basing on our data,we classify the superior clunial nerve into 4 types,Viz:one- branched:1 case;two-branched:15 cases;three-branched:66 cases;and four-branched:18 cases. More than one half of the medial and the most medial branches of the superior clunial nerves perforate through the deep surface of the attachment of the posterior layer of the lumbodorsal fascia on to the iliac crest,and enter the superficial fascia of the buttock.During acute wriggle of the loin,the firm fixation and tight stretching of the perforating branches by this attachment may cause partly the injury of the branches. The crossing point of the lateral margin of the sacrospinalis muscle and iliac crest or the area slightly medial to this point is the site where the perforating superior clun- ial nerve could be localized supeficialiy.

AIM: To investigate the effects of glioma cells on aquaporin expression in blood-brain barrier and their importance in pathophysiology. METHODS: A blood-brain barrier model was established by coculture of ECV304 and astrocytes in vitro . HPLC was used to determine the change of water transport of in vitro blood-brain barrier model after the influence of glioma cells. The expression levels of AQP1 and AQP4 were analyzed by semiquatitative RT-PCR. RESULTS: Glioma cells decreased expression level of AQP4 of astrocytes and induced abnormal expression of aquaporin-1 in endothelial cell line. The water transport of in vitro blood-brain barrier model from luminal side to abluminal side was increased after coculture with glioma cells. CONCLUSION: The vasogenic brain edema induced by glioma cells may not be the result of hyperpermeability of blood-brain barrier to macromolecules in plasma. The changes of aquaporin expression may be the molecular basis of brain edema induced by glioma cells.

Circulating tumor DNA (ctDNA) detection is one of "liquid biopsy"analysis. It has shown promising clinical application in cancer precise medicine due to its noninvasive sampling and real-time observation. Nowadays, ctDNA analysis has been clinically validated and successfully applied in advanced cancer, including selecting personalized treatment, monitoring treatment responses, minimal residual disease and recurrence. Although there has been rapidly increasing interests in ctDNA, its clinical application in cancer precise medicine is still facing few challenges, especially in screening and diagnosing cancer at early stages. Here, the latest progress in the applications and challenges of ctDNA in advancedstage tumor therapy were reviewed to provide references for future studies on ctDNA.
