Objective:To evaluate the efficacy of loop electrosurgical excision procedure(LEEP) in the treatment of different grade of cervical intraepithelial neoplasia(CIN). Methods:898 cases with CIN treated by LEEP were retrospectively analyzed. Operation time, blood loss during the operation, changes of histopathologic results and high-rick HPV before and after the operation were studied. The diagnosis and treatment results by LEEP were evaluated. Results: The average operation time was 5.1 minutes. The average blood loss during the operation was 5.6 ml. The concordance rate of pathologic results under colposcope before operation and after LEEP was 77.73% (698/898) .96 cases had increased CIN grade after LEEP(10.69%). The HPV-DNA loading dose after operation declined significantly (P< 0.01). Conclusions: The detection rate of invasive cervical cancer by LEEP is higher than multiple punch biopsy under electronic colposcope. LEEP is an effective method for the diagnosis and treatment of CIN, and it can eliminate high-rick HPV at the same time of ablating the cervical lesion.

Objective · To investigate the relationship between the results of thin prep cytologic test (TCT), high-risk human papillomavirus (Hr-HPV) detection and vaginalintraepithelial neoplasia (VAIN) after hysterectomy. Methods · A retrospective study was conducted of 56 patients with VAIN after hysterectomy. The analysis included TCT and Hr-HPV examination, clinical data and the relationship between Hr-HPV examinenation and histopathological examination of colposcopy. Results · Postoperative follow-up of TCT and Hr-HPV parallel pathological examination showed that 56 patients had vaginal stump lesions, including cervical factor hysterectomy accounted for 5.81% (45/775) and non cervical factor hysterectomy accounted for 0.19% (11/5933). The difference was statistically significant (P=0.000). In 56 cases of patients with vaginal stump lesions, Hr-HPV infection were 40 cases (accounting for 71.43%), uninfected patients were 16 cases (accounting for 28.57%). The Hr-HPV infection rates of cervical hysterectomy and non cervical factor hysterectomy patients were 80.00% (36/45) and 36.36% (4/11) respectively, and the difference was statistically significant (χ2= 6.248, P=0.012). TCT results showed that the incidence of squamous intraepithelial lesions were 42.22% (19/45) and 9.09% (1/11) respectively. Conclusion · The Hr-HPV infection rate and the morbidity of VAIN of the patients undergone hysterectomy due to the cervical lesionfactors is higher than those who had none cervical lesion factors. In order to identify VAIN early, patients who have the history of hysterectomy should undergo careful evaluation of cervical and vaginal circumstance before surgery and the routine examinations of TCT and Hr-HPV in the follow-up.

PURPOSE: The role of consolidation chemoradiation (CCRT) after systemic chemotherapy in locally advanced pancreatic cancer (LAPC) is still controversial. We aim to evaluate the effectiveness of CCRT in LAPC using systematic review and meta-analysis of prospective studies. MATERIALS AND METHODS: Prospective clinical trials of LAPC receiving chemotherapy with or without subsequent CCRT were included in the analysis. We systematically searched in PubMed, MEDLINE, Embase, and Web of Science. The primary outcome of interest was 1-year survival. Secondary end-points were median overall survival, progression-free survival, toxicity, and resection rate. RESULTS: Forty-one studies with 49 study arms were included with a total of 1,018 patients receiving CCRT after induction chemotherapy (ICT) and 954 patients receiving chemotherapy alone. CCRT after ICT did not improve 1-year survival significantly in LAPC patients compared with chemotherapy alone (58% vs. 52%). ICT lasted for at least 3 months revealed significantly improved survival of additional CCRT to LAPC patients compared to chemotherapy alone (65% vs. 52%). A marginal survival benefit of consolidation CCRT was noted in studies using maintenance chemotherapy (59% vs. 52%), and fluorouracil-based CCRT (64% vs. 52%), as well as in studies conducted after the 2010 (64% vs. 55%). CONCLUSION: The survival benefit of ICT+CCRT over chemotherapy alone in treating LAPC was noted when ICT lasted for at least 3 months. Fluorouracil-based CCRT, and maintenance chemotherapy were associated with improved clinical outcomes.

Hepsin, a transmembrane serine protease abundant in renal endothelial cells, is a promising therapeutic target against several cancers, particularly prostate cancer. It is involved in the release and polymerization of uromodulin in the urine, which plays a role in kidney stone formation. In this work, we design new potential hepsin inhibitors for high activity, improved specificity towards hepsin, and promising ADMET properties. The ligands were developed through a novel hierarchical pipeline. This pipeline explicitly accounts for off-target binding to the related serine proteases matriptase and HGFA (human hepatocyte growth factor activator). We completed the pipeline incorporating ADMET properties of the candidate inhibitors into custom multi-objective optimization functions. The ligands designed show excellent prospects for targeting hepsin the blood stream and the urine and thus enable key experimental studies. The computational pipeline proposed is remarkably cost-efficient and can be easily adapted for designing inhibitors against new drug targets.
