Objective To investigate the value of EBUS-TBNA (endobronchial ultrasound-guided trans-bronchial needle aspiration) in diagnosis of lung cancer and analyze its complications. Methods A retrospective study was carried out in our hospitalfrom March 2013 to March 2015. A total of 171patients received C-TBNA (Con-ventional transbronchial needle aspiration) first and got negative results. Therefore, they received EBUS-TBNA next. Weanalyzedthe sensitivity, specificity, accuracy of malignancy with EBUS-TBNA and positive (malignant) lymph node sites biopsied with EBUS-TBNAand the incidence of its complications. Results Lung cancer was proven in 107 patients who had received EBUS-TBNA, while 16 were benign cases. Thirty-onenegative patients received CT guided needle biopsy or surgeryfor finally pathology. Based on above statistical data , we calculated EBUS-TBNA′s sensitivity, specificity and accuracy in 88.42%, 100.00%and 94.21%respectively. A totalof 818 lymph nodes were punctured by EBUS-TBNA, 408 were malignancy. The rate of diagnosis for malignancy was 49.88%. The complica-tioncontained 1 in hemorrhage, 1 in infectionand no life-threatening conditionandno death. Conclusion The value ofdiagnosis in lung cancerisrelatively high with EBUS-TBNAin safety and efficient.

Objective To explore the clinical characteristics of and to provide help to the prevention and treatment of malignant chest tumor with nosocomial mixed fungal-bacterial infection.Methods From July 2007 to June 2015,pathogenic bacteria in sputum,blood,urine,chest incision,thoracic and abdominal fluid,and implantable medical biological material were cultivated in 5067 patients with malignant chest tumor suspected with infection.The clinical characteristics,source of specimen and pathogenic bacteria,the types of diseases,medical intervention activities of 142 cases detected with mixed fungal-bacterial infection were retrospectively analyzed.Fesult In 142 patients,104 patients at clinical stage Ⅲ-Ⅳ accounted for 73.2％,and 94 patients used antibiotics more than 14 days (66.2％);104 cases had implanted biological materials (74.7％);96 cases died (67.6％).A total of 167 strains bacteria were isolated.Sixty-one strains of G+ bacteria accounting for 36.5％ were mainly Epidermis staphylococcus and Staphylococcus aureus;106 strains of G-bacteria accounting for 63.5％ were mainly klebsiella pneumonia,Escherichia coli and baumanii;172 strains fungus mainly of Candida albicans were isolated (77.3％).Pathogenic bacteria sources were mainly sputum specimens + pharynx strip,blood culture and medical implant materials.In 72 lung cancer patients,squamous carcinoma and small cell carcinoma were 52.8％ and 33.3％ respectively,higher than adenocarcinoma (12.5％);In 42 esophageal cancer patients,postoperative patients were 42.9％.Parenteral nutrition patients with more than 10 days were 80.9％ higher than that of parenteral nutrition in patients with less than 10 days (19.1％).Conclusion Among malignant chest tumor patients with nosocomial mixed fungal-bacterial infection,the bacteria were found in staphylococcus aureus,klebsiella pneumoniae and E.coli and the fungus was Candida albicans.For clinical stage Ⅲ-Ⅳ,patients with parenteral nutrition for more than 10 days,having history of chemo or radiotherapy,with antimicrobial use for more than 14 days,and with implanted biological materials,should be warned about nosocomial mixed fungal-bacterial infection.

AIM:To establish an effective and rapid method to develop transplanted subcutaneous pancreatic carcinoma by inducing PANC-1 cells into nude mice, and then use this mouse model to evaluate the tumor-homing and gene-silencing effects of siRNA-loading nanoparticles in vivo.METHODS:Different numbers of PANC-1 cells in 100 μL or 300 μL PBS were inoculated subcutaneously into the right flank of BALB /c (nu/nu) mice.When the tumor volume reached 100 mm 3 , siRNACY 5.5 nanoparticles were injected through the mouse tail vein to perform in vivo imaging assay.Be-sides, the mice were randomly divided into 3 treatment groups treated with PBS, scrambled control RNA nanoparticles and siKras nanoparticles, respectively.The protein expression of Kras was detected by Western blotting and immunohistochemi-cal staining.RESULTS:After inoculated with 1 ×10 7 PANC-1 cells in 300 μL PBS, all mice developed tumors within 2 weeks.The in vivo results showed that siRNA-loading nanoparticles accumulated in the tumor tissues and exerted gene si-lencing effect.CONCLUSION:In the present study, an effective and rapid method was established for PANC-1 cells to induce transplanted subcutaneous pancreatic carcinoma in nude mice within 2 weeks, which is suitable for in vivo imaging and treatment evaluations as a reproducible and reliable way for the further experiments .

Objective To investigate the relationship of serum and carcinoma levels of plasminogen activator inhibitor-1 (PAI-1)with clinical characteristics in patients with endometrial carcinoma.Methods Serum level of PAI-1 was determined by using enzyme-linked immunosorbent assay(ELISA) in patients with endometrial carcinoma (n =40),uterine prolapsed with normal endometrial tissues(n=40).The protein expression of PAI-1 in endometrial tissue was detected by using immunohistochemistry in patients with endometrial carcinoma and uterine prolapse patients.Results Serum level of PAI-1 was higher in patients with endometrial carcinoma than in uterine prolapse patients with normal endometrial tissues(19.43±7.12 μg/L vs.6.58±2.33 μg/L,P＜0.05).The rate of positive expression of PAI-1 was higher in endometrial carcinoma tissue than in uterine prolapse tissue[62.5 ％ (25/40) vs.7.5 ％ (3/40),P ＜ 0.01].Compared with early-stage endometrial carcinoma,advanced endometrial carcinoma had an increased rate of positive expression of PAI-1 (P ＜0.01).Compared with endometrioid adenocarcinoma,other pathological types of endometrial carcinoma had an increased rate of positive expression of PAI-1 (P ＜ 0.05).Poorly differentiated endometrial carcinoma versus highly differentiated endometrial carcinoma had an increased positive rate of PAI-1 (P ＜0.05).The rate of positive expression of PAI-1 was higher in endometrial carcinoma with myometrial invasion than without myometrial invasion(25/31 vs.0/9,P＜0.01).Conclusions The expression level of PAI-1 may be related to the invasion and metastasis of endometrial carcinoma.

Objective To investigate the efficacy and safety of modified anterior vaginal wall repair in the treatment of anterior vaginal prolapse and cystocele in elderly women.Methods We retrospectively analyzed the clinical value of modified anterior vaginal wall repair in 58 elderly women with stage Ⅱ-Ⅳ anterior vaginal prolapse and cystocele,which were evaluated by pelvic organ prolapse quantitation (POP-Q) system.The modified anterior vaginal wall repair was based on the paravaginal repair as an add-on to a reverse bridge repair and cross stitching of bilateral sutures stemmed from vaginal repair.According to the condition of each patient,other pelvic floor repair,perineal laceration repair,and paraurethral fascia reinforcement might be performed at the same time.The curative effectiveness was subjectively and objectively evaluated in the postoperative follow-up.Results A total of 58 operations were successfully finished.The follow-up time was 6-24 months with an average of (14±8) months.The subjective cure rate was 100％ and the rate of objective cure defined as the top of the vagina above the level of ischial spine was 100％ at 3 months follow-up (n=58).The subjective and objective cure rate was 100％ and 96.6％ (56/58) at 6 months follow-up (n=58),100％ and 94.1％ (32/34) at 12 months follow-up (n=34),91.7％ (11/12) and 91.7％ (11/12) at 24 months follow-up (n=12),respectively.Conclusions The modified anterior vaginal wall repair is safe and effective for anterior vaginal prolapse and cystocele in elderly women.

OBJECTIVETo investigate the relationship between miR-501-5p expression and the clinicopathological factors in patients with lung adenocarcinoma in Xuanwei area.

METHODSSurgical specimens of lung adenocarcinoma and paired adjacent tissues from 24 patients with lung adenocarcinoma from Xuanwei area were examined for miR-501-5p expression using microRNA microarray technique and qPCR. Chi-square test was used to analyze the association of miR-501-5P expression with the clinicopathological characteristics of the patients. Multiple regression analysis was performed to analyze the association of miR-501-5p expression with the patients' gender, age, tumor stage, and preoperative CEA level.

RESULTSMicroRNA microarray analysis and qPCR validation results revealed significantly upregulated expressions of miR-501-5p in patients with lung adenocarcinoma from Xuanwei area (Plt;0.01). The microarray data showed an up-regulation of miR-501-5p by 3.17 folds in lung adenocarcinoma tissue compared with the adjacent tissue (P=0.22376, FDR=0.071395). Chi-square test indicated that miR-501-5p expression level was associated with the patients' age (f=7.168, P=0.014), TNM stage (f=36.627, P<0.01), and preoperative serum CEA level (f=30.045, Plt;0.01), but not with the patients' gender (f=3.612, P=0.071). Multiple regression analysis revealed that miR-501-5p expression was positively correlated with the patients' age, TNM stage of the tumor, and serum CEA (Plt;0.05).

CONCLUSIONmiR-501-5p expression is up-regulated in lung adenocarcinoma with significant associations with the patients' age, TNM stages and serum CEA level in patients from Xuanwei area, suggesting its potential role in the tumorigenesis and progression of lung adenocarcinoma in Xuanwei area.
