Objective To study the effect of tiotropium on urination disorder in benign prostatic hyperplasia (BPH) patients with chronic obstructive pulmonary disease (COPD).Methods In our prospective pilot study,96 BPH patients with COPD patients were enrolled as the treatment group and another 25 similar cases as the control group:In the former group tiotropium was administered and the control group was not.The two groups were compared in terms of the score by the international Prostate Symptom Score(IPSS),the quality of life by QOL,maximum flow rate (Q-max),average flow rate (Q-ave),time to Q-max (TTQ-Max),prostate volume (PVR) and bladder voiding efficiency (BVE) after six months treatment.Results As compared to the control,after six months treatment,such indexes in the treatment group as IPSS (15.1 ± 4.1,16.3 ± 3.4 and 14.7 ± 3.1,P =0.864),QOL(3.9 ± 0.8,4.0± 0.8 and 4.0 ± 0.9,P =0.992),Q-Max(ml/s) (8.5 ± 2.9,10.9 ± 2.2 and 9.0 ± 2.4,P =0.214),Q-ave(ml/s) (3.9 ±1.2,5.0 ± 1.4 and 3.8 ± 0.9,P =0.054),TTQ-Max(s) (11.1 ± 5.6,11.2 ± 4.0 and 10.4 ± 5.1,P =0.424),PVR(mL)(56.8 ± 33.3,62.3 ± 30.5 and 57.4 ± 29.5,P =0.981),BVE(%) (75.6 ± 13.8,72.7 ± 10.5 and 74.3 ± 12.1,P =0.992).showed no significant differences.Conclusion Tiotropium does not adversely affect lower urinary tract functions in BPH patients with COPD.

Forty-eight patients with subclinical Cushing's syndrome(SCS)were evaluated.Eleven of them underwent adrenalectomy(Group 1)and the other 37 cases did not(Group 2).Serum and urine corticosol, plasma ACTH and parameters related to metabolic syndrome(such as waist circumference,blood pressure,blood lipids and fasting plasma glucose)were measured.The data at diagnosis were compared with those during the survey.The results indicated that patients with SCS had a significantly high prevalence of metabolic syndrome.The symptoms and signs of metabolic syndrome could be improved after removing the tumor.Otherwise there is no improvement,some patients will even develop into overt Cushing's syndrome.

Objective To prepare the mB7-1-GPI-anchored Lewis vaccine and investigate its antitumor effects. Methods mB7-1-GPI was incorporated on Lewis tumor cells and mB7-1-GPI-anchoring tumor vaccine was prepared. The anti-tumor immunity induced by the prepared mB7-1-GPI-anchored Lewis tumor cell vaccine in tumor-bearing mice was observed. Results Flow cytometric analysis showed that mB7-1-GPI were positively expressed on the surface of Lewis tumor cells. After Lewis tumor cells incubated with mB7-1-GPI, the positive rate (PR) of mB7-1 antigen was 95.8% (0h), 93.6% (4h), 91.1% (8h) and the fluorescence intensity (FI) was 11.2(0h), 10. 6(4h), 9. 8(8h). The IL-2 and IFN-γ production of splenic lymphocytes + lewis cells was (25.9 ± 1.4) pg/ml, (56. 0± 3. 5 ) pg/ml. The IL-2 and IFN-γ production of splenic lymphocytes + lewis/mB7-1-GPI was ( 871.3 ± 10. 4 ) pg/ml, ( 1329. 0 ± 11.9 ) pg/ml. In 25 days, the mean diameter of tumor of Lewis/mB7-1 -GPI was shorter than Lewis( 1.4 ± 0. 21 )cm & ( 2. 5 ± 0. 27 )cm , P < 0. 05 ). Lewis tumor cell-bearing C57BL/6 mice treated with Lewis/mB7-1-GPI vaccine survived much longer than mice treated with Lewis vaccine ( 75.2 ± 2. 0 ) d & (40. 2 ± 2. 0 ) d ( P < 0. 05 ). Conclusion The Lewis tumor vaccine prepared with mB7-1-GPI fusion protein significantly inhibited the tumor growth in Lewis bearing mice. It represented an useful new strategy for attaching immunological factor onto tumor cell surfaces without genetic manipulation.

Objective To discuss the clinical manifestation and pathology of papillary renal cell carcinoma (PRCC).Methods From January 2007 to January 2012,the clinical and pathologic data of 25 patients (17 males and 8 females with average age of 54 years ranging from 24-76 years) with PRCC were retrospectively analyzed in combination with review of literature.The clinical stages of the tumor were as follows,Ⅰ in 16 cases,Ⅱ in 5 cases,Ⅲ in 4 cases.And the radiographic inspections of PRCC were compared with that of 100 randomly selected clear renal cell carcinoma (CRCC).Results All the PRCC cases had different imaging presentations compared with CRCC.CT attenuation of CRCC was higher than that of PRCC in corticomedullary,nephrographic and excretory phase (P<0.05).Heterogeneous enhancement was most commonly seen in CRCC than PRCC (P<0.05).There were 21 patients underwent radical nephrectomy,and 4 patients underwent laparoscopic nephron sparing surgery.The pTNM stages of the tumor were as follows,pT1N0M0 in 16 cases,pT2N0M0 in 5 cases,pT3aN0M0 in 2 cases,pT1N1M0 in 1 case,,pT2N1M0 in 1 case.Of these 25 patients,8 (32%) and 17 (68%) were diagnosed as type Ⅰ and type Ⅱ PRCC,respectively.All the 25 cases of patients were followed up from 6 to 60 months.One case died of metastasis,1 case died of cerebrovascular disease and the other 23 patients survived with tumor-free.Conclusions PRCC is a special type of RCC with low morbidity.Radiological examination can be used in the differential diagnosis of CRCC and PRCC before surgery.The prognosis after surgical treatment is good,but the adjuvant systemic treatment is to be study.

AIM:To observe and compare clinical effects of coaxial 1. 8mm microincision phacoemulsification and 3. 2mm small incision phacoemulsification.
●METHODS:A total of 117 eyes of 85 patients with age-related cataract in our hospital were divided randomly into two groups:43 patients (59 eyes) in the coaxial 1. 8 mm microincision cataract surgery group ( C - MlCS ) , 42 patients (58 eyes) in the coaxial 3. 2 mm traditional small incision cataract surgery group (C-SlCS). A total of 117 eyes were received phacoemulsification with intraocular lens implantation. Uncorrected visual acuity was recorded preoperatively and postoperatively at 1, 7, 30 and 90d. The effective phacoemulsification time and average ultrasound energy were recorded in surgery. Corneal endothelial cell and corneal topography were recorded preoperatively and postoperatively at 90 d.
●RESULTS:Uncorrected visual acuity ( logMAR) was no overall statistical significance difference between C-MlCS group and C-SlCS group (P>0. 05), but was significant statistical difference in different time-point within both groups(P<0. 05). Uncorrected visual acuity in different time-point had nothing to do with corneal wound size in cataract surgery(P>0. 05). On the 1 day after surgery, uncorrected visual acuity was 0. 16±0. 11 in C-MlCS group and 0. 22±0. 18 in C-SlCS group(P<0. 05). AVE was (7. 00± 2.72)% in C-MlCS group and (6. 16±3. 16)% in C-SlCS group (P>0. 05). EPT was (3. 09±1. 61)s in C-MlCS group and (3. 20±1. 92)s in C-SlCS group (P>0. 05). At 90 d after surgery, corneal endothelial cell loss percentage was (5. 81±2. 28)% in C-MlCS group and (5. 69±2. 38)% in C-SlCS group (P>0.05), SlA was (0.35±0.11) Din C-MlCS group and (0. 61±0. 13) D in C-SlCS group (P<0. 05).
● CONCLUSION: Compared with coaxial 3. 2mm traditional small incision cataract surgery, 1. 8mm coaxial microincision cataract surgery can get earlier visual rehabilitation and significantly reduce SlA. The coaxial 1. 8mm microincision cataract surgery is safe, effective and deserves further clinical applications.
