Objective To raise the awareness of the glandularis ureteritis. Methods Five cases with glandularis ureteritis confirmed by pathological examination from Jan 2001 to Jun 2012 were reviewed. The diagnosis was assessed on histopathologic studies in all. The clinical manifestations, the diagnosis and treatment were discussed. Results Resections of the affected ureter and ureteroplasty were undertaken for 2 patients. Ureteronephrectomy was performed for 2 patients because of serious hydronephrosis due to obstruction. Electrofulguration via-ureteroscopy was carried out for another patient. All patients have been well and without recurrence on following up for 15 to 152 months, with an average of 86.6 months. Conclusion Glandularis ureteritis is not frequently seen and the etiopathogenesis is not yet clear. Biopsy is very important for suspected neoplasm of ureter before performing nephrectomy.

Objective To explore the relationship between hypermethylation and expression of cadherin 1(CDH1)with lung cancer.Methods The semi-quantitative real-time methylation specific polymerage chsin reaction(MSP)were used to detect the promoter's relative methylation ratio of CDH1 in all 30 cases of lung cancer tissues,para-cancer lung tissues,distal lung tissues and 5 non-cancer lung tissue samples.Nested RT-PCR was used to detect the expression ratio of CDH1 mRNA.The western blot analysis was used to detect the expression of E-cad protein.The immunohistoeheroical method was used to confirm some negative results of western blot analysis.Results The relative methylation ratios was 0.13%-450.67%(median:33.61%)in cancer tissues,0.00%-177.02%(median:18.04%)in para-cancer tissues,and 0.00%-51.68%(median:13.69%)in far-cancer tissues.Statistical significance between cancer and pars-cancer tissues(Z=-2.355,P＜0.05)and between cancer and disial tissues(Z=-3.527,P＜0.01)were found.The results of nested RT-PCR showed that there were statistical sigaificance of mRNA expression between lung cancer tissues and pars-cancer tissues,distal lung tissues or non-cancer lung tissues(F=9.081,P＜0.01).The results of western blot showed that the positive expression rate of E-cad was 36.7% in lung cancer tissues,70.0%in para-cancer tissues,and 96.7% in far-cancer lung tissues,respectively.There was a statistical significance of positive rate pf E-cad expression between lung cancer tissues and pars-cancer tissues or diatal tissues(X2=6.70,24.30,7.68,P＜0.01).Conclusions The study showed that transcription of CDH1 mRNA would be silenced by hypermethylation of CDH1 promoter,resulting in the decreased expression of E-cad.The aberrant hypermethylation of E-cad is implicated in lung cancer.

Objective To investigate the applied perineal anatomy of the pudendal nerve of female and its direction to perineal operation.Methods The gross anatomy were done on 20 female cadaver(ensuring the pelvic,the hip and the perineum were intact).In each cadaver,the dissection proceeded from intrapelvic,the pudendal canal(Alcock'canal) and the ischiorectal fossa.The composition,track,abut,ramus and domination area of female pudendal nerve were examined.Results The gross anatomy showed that the pudendal nerve was composed of the ventro-branches of sacral nerve 2~4(S_2~S_4).The pudendal nerve sends off anal branch at level of the ischial spine.And the trunk courses in the internal pudendal canal forwardly and inwardly send off the perineal nerves and dorsal nerve of clitoris.The perineal nerves sends off branches to back lunar labium,muscle and urethra.The dorsal nerve of clitoris sends off the nerve to skin of clitoris,and some to the urethra simultaneously.The pudendal nerve has different abut in different anatomical position.Conclusions The perineal anatomy of the pudendal nerve has the meaningful direction to the perineal operations.

Objective:This study aimed to analyze and summarize the clinicopathologic characteristics and treatment protocols of large cell lung carcinoma (LCLC). Methods:Clinicopathologic data of 83 cases with LCLC confirmed by pathology in 2012 were retrospectively reviewed. Results:Exactly 83 cases of LCLC accounted for 5.4%of lung cancer in 2012. Sixty-three cases were male and twenty were female. The average age was 60.4 years old. The average maximum diameter of the tumor was 4.6 cm. The common manifestations in imageology were peripheral type. Only four cases were correctly diagnosed by sputum exfoliocytology, biopsy of bronchofibroscope, and paracentesis before surgery. Sixty-three cases (76%) underwent surgical resection, and pulmonary lobectomy was mainly selected. Postoperative pathology diagnosis indicated that 39 cases were classic large cell carcinoma, 31 were large cell neu-roendocrine carcinoma, 2 were combined large cell neuroendocrine carcinoma, 8 were basaloid carcinoma, 2 were clear cell carcinoma, and 1 was lymphoepithelioma-like carcinoma. Each subtype of LCLC had respective characteristics of pathomorphology and immuno-histochemistry. Lymph node metastasis occurred in 62 cases (75%). Conclusion:The incidence rate of LCLC, which is a highly aggres-sive malignancy, is low. The clinical manifestation and imageology characteristics of LCLC do not have specificity, and its final diagno-sis depends on pathology diagnosis. Operation is the main treatment method. Improving the diagnosis rate of LCLC and further subdi-viding the pathological subtypes are important for a normalized comprehensive treatment of LCLC.

Objective To study safety and efficacy of transurethral Thulium laser resection of high-risk stage bladder tumor in anticoagulant state.Methods A total of 26 non-muscle invasive bladder cancer patients receiving long-term anticoagulant therapy,including 16 cases with cerebral infarction,7 cases with coronary heart disease,3 patients with coronary stenting,were retrospectively analyzed in our hospital from July 2012 to July 2014.In condition not stopping anticoagulants,Thulium laser transurethral resection of bladder tumor was performed,and hemoglobin,thrombin time,the operative time,intraoperative blood loss,postoperative bladder irrigation duration,postoperative hospital stay,bladder tumor recurrence within two years,the postoperative complications were recorded before and after surgery.Results All patients were successfully treated.The operative time was(29.1 ± 12.8) min,int raoperative blood loss was (29.4 ± 16.9) ml portions,postoperative bladder irrigation time was (1.25 ± 0.55) d,postoperative hospital stay was(5.51 ± 1.06) d.Hemoglobin before and after operation were (131.35 ± 6.57) g/L and (129.75 ± 11.05) g/L respectively,there was no statistically significant differences (t =1.014,P ＞ 0.05) between them.Prothrombin time before and after operation were (12.50 ± 0.25) s and(12.44 ± 0.27) s,with no statistically significant difference (t =0.908,P＞0.05)between them.During the followed-up of 48 months,tumor recurred at heterotopia in 2 patients.Conclusions Thulium laser transurethral resection of bladder tumor is safe and effective for patients undergoing long-term oral anticoagulation drugs,without a needto stop taking anticoagulant drugs.

Objective:To investigate the clinical effect of the anterolateral thigh perforator chimeric flap in the treatment of the wound of diabetic foot ulcer (DFU) .Methods:From January, 2018 to December, 2019, 14 cases wound of DFU of type II diabetic were treated by anterolateral thigh chimeric perforator flap. The patients were 10 males and 4 females, at 49 to 58 years old. Of the 14 patients, 10 with simple peripheral neuropathy, 4 with peripheral neuropathy complicated with vascular disease, and none with single vascular disease. With strict control of patients' blood glucose, antibiotics blended bone cement was applied or filled onto grade 2 or higher grade Wagner's DFU after debridement. In addition, the anterolateral thigh chimeric perforator flap was transferred 2 to 3 weeks later. The size of flap was 8 cm×3 cm-27 cm×7 cm. Regular followed-up were made after surgery.Results:Thirteen flaps survived in one stage after surgery. The other 1 flap had venous vascular crisis, and survived completely after active exploration. The patients were followed-up for 6-12 months. All the flaps survived well in good shape and texture. The donor and recipient areas healed well. The functional recoveries of the DF were satisfactory.Conclusion:Application of anterolateral thigh perforator chimeric flap in repair of the refractory wound of DF achieves a good clinical outcome and effectively improves the life quality of patients.

BACKGROUNDGejiu in Yunnan Province is a region where the incidence of lung cancer is high among the miners of tin mine. Our previous research team successfully induced the malignant transformation of immortalized human bronchial epithelial cells (BEAS-2B) by Gejiu mineral powder in vitro. The objective of this study is to explore the role of survivin and proliferating cell nuclear antigen (PCNA) in the pathway of the malignant transformation of BEAS-2B induced by Gejiu mineral powder.

METHODSProtein expression of survivn and PCNA in BEAS-2B cells and its malignant transformation cells was respectively evaluated by immunofluorescence cytochemistry staining technique and immunohistochemistry.

RESULTS(1)The expression of survivin protein was negative in BEAS-2B cells and was positive in its malignant transformation cells by immunofluorescence cytochemistry staining techniques. And the protein level of PCNA was low in BEAS-2B cells and high in its malignant transformation cells. (2)The positive expression of survivin protein in BEAS-2B cells (0/20) was significantly lower than that in its malignant transformation cells (85%, 17/20) by immunohistochemistry (P < 0.001). And the labelling index (LI) of PCNA in BEAS-2B cells was significantly lower than that in its malignant transformation cells (P < 0.001). LI of PCNA in the malignant transformation cells of BEAS-2B with positive expression of survivin was significantly higher than that with negative expression of survivin (P < 0.001).

CONCLUSIONS(1)The up-regulation expression of survivin in malignant transforma- tion cells of BEAS-2B suggests that survivin may play an important role in the pathway of malignant transformation in BEAS-2B cells induced by Gejiu mineral powder. It may give a proof for revealing the carcinogenesis of lung cancer in Gejiu miner. Survivin may be identified as a novel potential diagnostic and therapeutic target of lung cancer in Gejiu miner. (2)The up-regulation expression of PCNA in malignant transformation cells of BEAS-2B suggests that cell proliferation may play an important role in the pathway of malignant transformation. (3)Survivin may promote cell proliferation mediated by PCNA. Survivn and PCNA may play synergetic roles in the process of malignant transformation in BEAS-2B cells induced by Gejiu mineral powder.

Objective To discuss the long term clinical effect of ileal orthotropic neobladder.Methods From 1991 to 1998,79 patients,mean age 55(41～75)years,male 74,female 6,were followed up.The serum creatinine and urea,electrolytes,blood routine,B ultrasonic scan of the neobladder residual urine and IVU or MRU of the patients were followed up.The max transverse diameter of renal pelvis and the max verticaI/level diameter of neobladder were measured in 5,10 to 14,15 years of postoperative when IVU or MRU.All results of different time were compared by the multiple comparisons.The local or distant cancer recurrence and the complications of the operation Were evaluated. Results Sixty-four cases,58 male,6 famle,were long term followed up:mean time was 167 (range,121～216)months.Seven cases died of other diseases.Seven cases had pelvic recarrence.Two cases had urethral recurrence.Three cases died of tumor metastasis.One case had ureter recurrence.Forty-eight patients were alive more than 10 years.The value of the serum creatinine,urea,electrolytes and bloods routine of the patients were normal after 5,10 to 14 and 15 vears postoperative (P＞0.05).The max transverse diameter of the renal pelvis in 5,10 to 14 and 15 years Dostoperative were 14.0 mm,14.1 mm and 13.7 mm,respectively,P＞0.05.The max vertical/level diameter of the neobladder in 5,10 to 14,15 years of postoperative were 110.4 mm/90.4 mm,111.5 mm/95.3mm and 127.0 mm/97.0 mm,respectively,P＞0.05.The residual urine of 5 cases was more than 50 ml and had not increased during follow up.Eight cases with neobladder stone were cured by the intracavitary lithothrypsis.Two cases with uretheral stricture were cured by the intracavitary therapy.Twelve cases of 14 cases with inguinal hernia were cured by reoperation,2 cases accepted conservative treatment.Only 17 cases had no complication involve of the cancer and the operation.

Objective: To investigate the incidence and prognosis of cognitive impairment and to find out the risk factors associated with the outcome for better understanding and preventing cognitive impairment in maintenance hemodialysis (MHD) patients. Methods: The patients who met the criteria as below: MHD patients (≥3 months) in Renji Hospital, Shanghai Jiao Tong University School of Medicine from January 2000 to July 2014, ≥18 years old were enrolled and could carry on the montreal cognitive assessment (MoCA) of voluntary cooperation. According to the score of MoCA, all enrolled patients were divided into two groups: cognitive impairment (MoCA<26) group and non-cognitive impairment (MoCA≥26) group. The follow-up period was 3 years. There were 130 males, and the incidence, demography data, medical history, hemodialysis data, laboratory examination and prognosis of cognitive impairment in hemodialysis patients were prospectively compared and analyzed. Logistic regression analysis was used to investigate the risk factors of cognitive impairment. Kaplan-Meier survival curve and Cox regression model were used for prognostic analysis. Results: A total of 219 MHD patients were enrolled. The incidence of cognitive impairment in MHD patients was 51.6%. There were 130 males, and the ratio of male to female was 1.46∶1. Age was (60.07±12.44) years old and dialysis vintage was (100.79±70.23) months. Compared with non-cognitive impairment group (n=106), patients in cognitive impairment group (n=113) were older, and had higher proportion of education status<12 years, history of diabetes and anuria (all P<0.05); however, the post-dialysis systolic pressure, pre-dialysis diastolic pressure, post-dialysis diastolic pressure, platelet and spKt/V were lower (all P<0.05). Multivariate logistic regression analysis showed that education status<12 years (OR=3.428, 95%CI 1.919-6.125, P<0.001), post-dialysis diastolic pressure<73 mmHg (OR=2.234, 95%CI 1.253-3.984, P=0.006) and spKt/V<1.72(OR=1.982, 95%CI 1.102-3.564, P=0.022) were the independent risk factors for cognitive impairment in MHD patients. The Kaplan-Meier survival curve analysis showed that the survival rate of patients with cognitive impairment was lower than that of non-cognitive impairment group in MHD patients during 3 years follow-up (χ²=3.977, P=0.046). Multivariate Cox regression analysis showed that cognitive impairment was an independent risk factor for death in MHD patients (RR=2.661, 95%CI 0.967-7.321, P=0.058). Conclusions Cognitive impairment is one of the common complications and an independent risk factor for death in MHD patients. The mortality is high in patients who suffer cognitive impairment. Education status<12 years, post-dialysis diastolic pressure<73 mmHg and spKt/V<1.72 are the independent risk factors for cognitive impairment in MHD patients.
