Objective To retrospectivly analyze the value of Pap smear,liquid-based cells, colposcopy and colposcopic cervical biopsy in the diagnosis of cervical cancer. Methods 116 cases of cervical cancer were retrospectively analyzed, and the value of Pap smear,liquid-based cells ,colposcopy,and colposcopic cervical biopsy in the diagnosis of cervical cancer were investigated. Result 116 patients were pathologically diagnosed with cervical cancer before and after surgery. Pap smear was performed for 30 patients (25.9%) ,and 10 patients (33.3%) were detected with HSIL. Liquid-based cells was performed for47 patients (40.5%) ,and 25 patients (53.1%) were detected with HSIL. Colposcopy was performed for 99 patients (85.3%), and 75 patients (75.8 % ) were detected with HSIL or invasive cancer. Preoperative colposcopic biopsy was performed for 99 patients, and the pathological coincidence rate was 94.9%. There was no significant difference statistically between two cytology screening ( P ＞ 0.05 ). There was significant difference statistically between liquid-based cells and colposcopy ( P ＜ 0.01 ). There were significant differences statistically among liquid-based cells,colposcopy ,and colposcopic cervical biopsy ( P ＜0.01 ). Conclusion Cytology, colposcopy, colposcopic cervical biopsy could not be individually more complete and accurate detection of cervical cancer. Colposcopy,colposcopic biopsy than cytology had higher accurate rate of diagnosis of cervical cancer. A reasonable combination of multiple detection methods could improve the diagnostic accuracy of cervical cancer.

Objective To investigate the role of phosphatidylinositol 3-kinase (PI3K)/protein-serine-threonine kinases(Akt) signal transduction pathway in EphB receptor-mediated neuropathic pain in rats.Methods Forty-eight pathogen-free male SD rats aged 2-3 months weighing 150-180 g were randomly divided into 6 groups (n =8 each):groups sham operation (groups S1 and S2 ); groups chronic constrictive injury (CCI) (groups C1and C2 ) and groups EphBI-Fc (EphB receptor antagonist) + CCI (groups E1 and E2 ).Neuropathic pain was induced by placing 4 ligatures on left sciatic nerve at 1 mm intervals with 5-0 silk thread in groups C1,C2,E1 and E2.EphBI-Fc 0.5 μg in 5 μl normal saline was injected intrathecally 1 h before operation and at 1 and 2 d after operation (group E1 ) or on 5th day after operation (group E2).Normal saline 5 μl was injected intrathecally instead of EphBI-Fc 1 h before operation and at 1 and 2 days after operation (groups S1 and C1 ) or on 5th day after operation (groups S2 and C2 ).Pain withdrawal latency to noxious thermal stimulation (PWL) and pain withdrawal threshold to noxious mechanical stimulation (PWT) were measured before operation and at 1,3 and 5 d after operation.The animals were sacrificed at 5 d after operation after measurement of pain threshold.The lumbar segment of spinal cord (L4-6) was removed for determination of c-Fos,PI3K and phosphorylated Akt(p-Akt) expression.Results CCI significantly reduced PWL and PWT and up-regulated spinal c-Fos,PI3K and p-Akt expression in groups C1 and C2 as compared with groups S1 and S2.EphB1-Fc significantly decreased hyperalgesia and the upregulated spinal Fos,PI3K and p-Akt protein expression induced by CCI in groups E1 and E2 as compared with groups C1 and C2.Conclusion Spinal EphB receptor is involved in the development and maintenance of neuropathic pain through PI3K/Akt signal transduction pathway.

Objective The cyst excision is considered as priority management of the female paraurethral cyst.The purpose of this present study was to explore the feasibility and safety of the two-step excision with treatment for the female paraurethral cyst.Methods Twenty eight consecutive women with paraurethral cyst underwent paraurethral cyst removal were enrolled retrospectively in this study from October 1,2005 to August 12,2008 in Urology Department of West China Hospital.Results All cases were followedup from 6 months to 2 years,no recurrence occurred.No complications such as urethral stricture and urethralvaginal fistula were found.Conclusions The 2-step excision is the reference technique for cure of female paraurethral cyst.Urethra injury was avoided efficiently,because anatomical relationship between cyst and urethra could be clearer when the technique of 2-step excision was applied.

Objective To analyze and compare clinical application of two types of clavicular hook plates. Methods From September 2000 to October 2003, 33 cases with acromioclavicular joint dislocation (Tossy Ⅲ) or distal clavicle fractures (Neer Ⅱ) were treated with insertion type (AO/ASIF) or knuckle-protruded type (WALDEMAR LINK) clavicular hook plates. The former one was used in 18 cases and the latter one in 15. Results In insertion type group, the average operation time was 28 minutes, with average incision length for 7.6 cm. All the cases got good reduction and fixation without any subluxation, except for one case suffering from impingement of the shoulder joint. In knuckle-protruded type group, the average operation time was 40 minutes, with an average incision length for 9.8 cm. After operation, one case lost hooking-up, one had born shoulder joint impingement, while another two suffered from skin pain at acromion caused by hook tip for a long time. Except for one case losing hooking-up, all cases of both groups achieved good recovery of function of shoulder joint and won satisfactory reduction without any redislocation after the implants being taken out. Conclusion Because of the advantages like convenient manipulation, short operation time, minor incisions and less potential complications, the insertion type clavicular hook plate is more suitable for cases with Tossy Ⅲ or Neer Ⅱ fractures.

Objective To evaluate the efficacy of dezocine for prevention of postoperative cognitive dysfunction (POCD) in elderly patients undergoing total knee arthroplasty under remifentanil-based anesthesia.Methods Sixty-eight patients of both sexes, aged 65-85 yr, weighing 48-78 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , undergoing elective unilateral total knee arthroplasty under general anesthesia, were randomly divided into 2 groups (n =34 each) using a random number table: control group (group C) and dezocine group (group D).After induction of anesthesia, the patients were tracheally intubated and mechanically ventilated.Anesthesia was maintained with iv infusion of propofol 0.05-0.06 mg · kg-1 · min-1 and remifentanil 0.05-0.10 μg · kg-1 · min-1, and intermittent iv boluses of vecuronium 0.04 mg/kg.Dezocine 0.1 mg/kg was injected intravenously at 30 min before skin incision in group D.At 1 day before operation (T0) , and 1, 3, 5, 7 days after operation (T1 , T2, T3 , T4) , the blood samples from the central vein were collected for determination of serum cortisol (Cor), neuron specific enolase (NSE) and S-100β protein concentrations.Before operation, and 5 and 7 days after operation, the patients' cognitive function was assessed using Mini-Mental State Examination, and the occurrence of POCD was recorded.Results Compared with the baseline value at T0, the serum Cor, NSE and S-100β protein concentrations were significantly increased at T1-3, and MMSE scores were decreased at T3,4 in the two groups.Compared with group C, the serum Cot, NSE and S-100β protein concentrations were significantly decreased at T1-4, and Mini-Mental State Examination scores were increased at 5 and 7 days after operation, and the incidence of POCD was decreased in group D.Conclusion Dezocine 0.1 mg/kg intravenously injected at 30 min before skin incision can prevent the occurrence of POCD in elderly patients undergoing total knee arthroplasty under remifentanil-based anesthesia.

Background and purpose: High-dose chemotherapy followed by autologous stem cell transplantation (auto-HSCT) is considered as the ifrst line treatment for patients with relapse/refractory lymphoma after conventional chemotherapy. However, most of these patients still relapse the second time. The purpose of this study was to analyze the efifcacy of the consolidation chemotherapy after autologous stem cell transplantation (HSCT) refractory/relapse lymphoma in high risk. Methods:A total of 38 patients with relapsed/refractory lymphoma including Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) were included, who were underwent auto-HSCT in our transplan-tation department from Jan. 2010 to Dec. 2013. In treatment group, 19 patients received 2 courses of consolidation che-motherapy after auto-HSCT every 2 to 3 months, with the regimen of mini-BEAM or modiifed mini-CBV. Another 19 patients had no chemotherapy after auto-HSCT as control group. Results:The median follow-up duration was 17.2 and 7.5 months in the treatment and control group respectively. The follow-up data demonstrated prolonged progression-free survival (PFS) in the treatment group than the control group [24.7 months vs 7.8 months, P=0.029 under intend-to-treat analysis ITT;24.7 months vs 5.2 months, P=0.01 under per protocol analysis(pp)]. There is also a trend of improved overall survival (OS) in the treatment group (P=0.055, ITT). Conclusion:Consolidation chemotherapy after auto-HSCT for refractory/relapsed lymphoma patients delay the relapse and tend to improve the overall relapse rate.

Aim To observe the effect of kanamycin on the change of Ca2+ concentration in outer hair cells caused by acetylcholine to explore the relationship between kanamycin ototoxicity and the cochlear efferent nervous system.Methods After the guinea pigs were killed by decapitation,the OHCs were isolated in artificial perilymph and divided into three groups:control group,acetylcholine(ACh) group and kanamycin + ACh group.OHCs were loaded with Fluo-3/AM for 30 min and then the change of Ca2+ fluorescence intensity was observed.Results Ca2+ fluorescent intensity in OHCs remained basically unchanged in control group,increased 3.06 times(n=6) in ACh Group,and increased 1.75 times(n=6) in kanamycin +ACh Group.Conclusions Kanamycin can obviously inhibit the increasing of Ca2+ concentration in OHCs caused by ACh.
