Objective To investigate the expression and clinicopathological features of gene associated with retinoid-interferon mortality-19 (GRIM-19) in epithelial ovarian carcinoma.Methods The expression of GRIM-19 gene in tissues from 138 cases of epithelial ovarian carcinoma,102 cases of benign ovarian epithelial tumor and 46 cases of normal ovarian tissues were detected by Immunohistochemistry and Western blot methods.Assembled clinical survival data were analyzed with Kaplan-Meier and Cox regression models.Results The expression level of GRIM-19 in epithelial ovarian carcinoma (3.4 ± 2.0) was lower than that in benign ovarian tumor tissues (4.7 ± 2.9) and that in normal ovarian tissues (7.5 ± 2.2 ; P ＜0.01).The level of GRIM-19 expression was related to the survival time of epithelial ovarian carcinoma patients by Kaplan-Meier analysis (P =0.002).The shorter survival time of epithelial ovarian carcinoma patients was significantly associated with the level of GRIM-19 expression (P =0.001),clinical stage (P =0.001),volume of ascites (P =0.023) and the largest diameter of the primary tumor lesion (P =0.044) by Cox regression models.Conclusions The low expression of GRIM-19 in the epithelial ovarian carcinoma suggests that GRIM-19 may be a key gene involved in its carcinogenesis.The expression level of GRIM-19 may be also an independent prognostic factor for epithelial ovarian carcinoma patients.

Objective To explore the value of combined biliary and duodenal stenting in the palliative treatment of pancreatic head carcinoma. Methods From August 2003 to July 2005, four patients who were diagnosed as pancreatic head carcinoma presenting obstructive jaundice were treated with biliary stenting. When duodenal obstruction occurred due to the growth of the carcinoma , duodenal stents were placed to relieve the obstruction. Results The biliary and duodenal stents were successfully positioned in all 4 patients. After biliary stents were inserted, the level of total bilirubin value of each patient decreased by 50% in 24 hours and returned to normal range within 1 week. When the biliary stents were occluded, stent replacement or restenting was performed, and relief of obstructive jaundice was thus achieved. After duodenal stents were inserted, the symptoms of duodenal obstruction were relieved and the patients were able to tolerate peroral solid food. When the duodenal obstruction recurred, a second coaxial duodenal stent was inserted. Three duodenal stents were placed in one patient because of rgrowth in size of the carcinoma. No complications related to stenting were observed. Two patients were followed up until their death with survival time of 24 months and 22 months, respectively, who were free of jaundice and duodenal obstruction at the end of their life. Two patients are still in follow-up period (16 months and 9months after stenting, respectively), who are now free of jaundice and duodenal obstruction. Conclusion Biliary stenting combined with duodenal stenting can improve the life quality of patients with pancreatic head carcinoma and is an effective palliative treatment for these patients.

OBJECTIVEThis study aims to do the following: construct a three-dimensional finite element model of an labial inverted impacted maxillary central incisor and its supporting tissues, analyze stress distribution in the periodontal tissue when various tractions are exerted, and provide references for treating impacted maxillary central incisor.

METHODSA three-dimensional finite element model oflabial inverted impacted maxillary central incisor and its periodontal tissues was established using Mimics 10.01 and Ansys 14.0 software based on original cone beam computed tomography (CBCT) data. Various traction values (20, 30, 40, 50, 60, and 70 g) were exerted on the incisal margin in the direction perpendicular to the impacted tooth. Different Von Mises stress values were determined.

RESULTSStress distribution on the periodontal ligament increased with traction size. When 30 g traction was exerted on the labial inverted impacted maxillary central incisor, the Von Mises stress was 24 919.0 Pa, which was within the range of the optimum force and close to its maximum value.

CONCLUSIONThe optimum traction for early orthodontic treatment of labial inverted impacted maxillary central incisor is nearly 30 g.

Objective To compare the safety and efficacy between RevoLix 2 μ m continuous-wave (CW) laser resection of bladder tumor and transurethral resection of bladder tumor (TURBT) in patients with non-muscle-invasive bladder tumor, and to evaluate clinical value of 2 μ m CW laser resection for nonmuscle-invasive bladder tumor. Methods 62 patients with non-muscle-invasive bladder tumor were divided into 2 groups including 2 μ m CW laser resection group (32 cases) and TURBT group (30 cases) according to the random number table.The intravesical instillation of pirarubicin was performed regularly. The operative time,drop in hemoglobin,indwelling catheterization time,and operative complications were analyzed.Results All cases were completed successfully. The mean operative times of 2 μm CW laser resection group and TURBT group were 32.5±10.5 min and 31.3± 9.8 min, respectively, and no statistical difference could be found between both groups (t =0.364,P=0.674).3 cases were found to have obturator nerve reflex in TURBT group,but no obturator nerve reflex was found in 2 μn CW laser resection group.Bladder irrigation time of 2 μm laser resection group was statistically shorter than that of TURBT group [ (6.2±2.6)h vs (23.8±6.5)h,t =8.294,P=0.006]. There was also no significant difference in postoperative catheterization time between both groups [(4.2±1.5)d vs (5.2±1.8)d,t=1.468,P=0.103 ]. Postoperative hospitalization time of the two groups was not shown significant difference [ (5.3± 1.5) d vs (5.8±2.8) d,t =0.627,P =0.531 ].All cases were followed up for 6～18 months,and there were no significant difference in the recurrence rate between both groups (x2=0.481,P =0.562). Conclusion 2 μm CW laser resection is a novel excellent treatment for non-muscle-invasive bladder tumor and has the similar effect as TURBT with the advantage of significantly less blood loss and rapid recovery after surgery.

Objective To evaluate the impact of 120 W 2 μ m continuous-wave laser vapoenucleation versus and transurethral resection of the prostate (TURP) in patients with symptomatic benign prostatic hyperplasia (BPH) on sexual function.Methods One hundred and twenty-two patients with BPH were selected,63 cases were treated with 120 W 2 μ m continuous-wave laser vapoenucleation versus(2 μ m laser group),59 cases were treated with TURP(TURP group).International index of erectile function(IIEF) scores and self-made general assessment questions were completed before and 12 months after treatment to determine the impact on sexual function.IIEF scores included erectile function (EF),sexual desire,orgasm,sexual satisfaction and overall satisfaction.Results The IIEF scores difference was no significant before treatment between two groups (P ＞ 0.05).In two groups,there was no significant difference in EF,sexual desire,sexual satisfaction and overall satisfaction score between before treatment and 12 months after treatment(P＞ 0.05),orgasm score 12 months after treatment was significantly lower than that before treatment [2 μm laser group:(5.9 ± 1.5) scores vs.(8.6 ± 2.7) scores;TURP group:(5.5 ± 1.6) scores vs.(8.7 ± 1.8) scores] (P ＜0.05).Multiple linear regression analysis showed that two groups EF score and the international prostate symptom score,quality of life score and Q.~ positive linear correlation.Logistic regression analysis showed that the incidence of retrograde ejaculation and orgasm reduced significantly assoeiated(P ＜ 0.05),as an independent predictor of orgasm reduced after treatment(P ＜ 0.05).Conclusions There is no difference between these two surgical techniques regarding to impact on sex function.No significant EF improvement after surgery in both groups,but these two techniques can significantly decrease the IIEF orgasmic function domain and this is mainly caused by retrograde ejaculation.

Objective To measure the level of circulating endothelial progenitor cell (EPC) and serum vascular endothelial growth factor (VEGF), and to investigate its clinical significance in patients with different stages of renal cell carcinoma (RCC). Methods The level of circulating EPC was quantified by assaying CD45-CD34+VEGFR-R2 +cell phenotype in 45 patients with RCC (RCC group), 30 patients with benign renal tumors(benign renal tumors group) and 30 healthy controls (control group). Serum VEGF was quantified by enzyme- linked immunosorbent assay (ELISA). The results were compared. Results The level of EPC in RCC groups was (0.265 ± 0.042)%, in benign renal tumors group was(0.053 ± 0.008)% , and in control group was (0.048 ± 0.006)%. The level of EPC in RCC group was significantly higher than that in benign renal tumors group and control group (P<0.05). The level of EPC in Ⅲ- Ⅳ stage patients was significantly higher than that in Ⅰ-Ⅱ stage patients:(0.312 ± 0.038)%vs. (0.215 ± 0.021)%, P<0.05. Three months after operation, the level of EPC in 33 RCC patients without pretreatment was (0.078 ± 0.003)% and significantly lower that before treatment (P<0.05). The level of VEGF in RCC groups was (305.5 ± 29.1) ng/L, in benign renal tumors group was (29.8 ± 3.2) ng/L, and in control group was (25.1 ± 2.8) ng/L. The level of VEGF in RCC group was significantly higher than that in benign renal tumors group and control group (P<0.05). The level of VEGF inⅢ-Ⅳstage patients was significantly higher than that inⅠ-Ⅱstage patients:(365.6 ± 34.6) ng/L vs. (256.2 ± 23.2) ng/L, P<0.05. Pearson association analysis showed that the level of EPC had positive associations with VEGF (r=0.714, P<0.01). Multiple linear regression showed that the size of kidney neoplasms was a dependent factor for the level of EPC. Conclusions The level of EPC has a positive association with VEGF. EPC maybe a new biomarker for RCC.

Objective: To determine human tear proteins using nanoliter liquid chromatography coupled to quadrupole orbitrap mass spectrometry (NanoLC-Q-Orbitrap-MS), and perform a bioinformatics analysis of main proteins. Methods: Human tear samples were collected with capillary, transferred to 3 kDa ultrafiltration tubes containing 400 μL of superpure water and centrifuged at 12 000×g for 15 min. Repeated extraction of tear proteins were performed four times, and following digestion with trypsin, the proteins were separated using the Waters NanoAcquity peptide BEH C18 column (1.7 μm, 100 μm×100 mm) and determined using NanoLC-Q-Orbitrap-MS with the mobile phase of 0.1% formic acid aqueous solution and acetonitrile (0.1% formic acid) in the full MS/dd-MS2 mode. The types of proteins were characterized in the Uniprot database using the software Proteome Discoverer version 2.1 and verified using bovine serum albumin. The tear proteins were subjected to gene annotation analysis using the String database. Results: A total of (387±160) human tear proteins were yielded, with a relative standard deviation (RSD) of 4.13%, and there were 25 types of proteins with a relative high abundance, including lipocalin 1, lysozyme and lactoferrin. The peptide sequence coverage of bovine serum albumin was (86.08±2.61)%, with a RSD of 3.03%. The 25 major tear proteins were involved in substance transduction among cells, homeostasis process, negative regulation of the endopeptidase activity, detection of chemical stimulants and humoral immune responses, and the 16 proteins had close interactions. Lacritin, lipocalin 1, lactoferrin, lysozyme and zinc-α 2-glycoprotein, which had a relative high abundance, had close biological connections. Conclusion NanoLC-Q-Orbitrap-MS is stable, reliable and feasible for detection of multiple proteins in tears.
