Underactive bladder is the main part of lower urinary tract symptoms. As a conservative treatment, intravesical electrical stimulation can improve the function of bladder sensation, and promote micturition. Intravesical electrical stimulation is effective and safe on underactive bladder, both idiopathic and neurogenic. Rectilinear biphasic waveform, low frequency and short pulse width stimulation was recommended.

Objective To discuss the application effect of fansclub informatization on the self-management of breast cancer patients. Methods A total of 240 breast cancer patients were equally divided into the experimental group and the control group by the random number table with 120 patients in each group. The control group was provided with routine health education, based on this, patients of the experimental group participated in the fans club. The compliance, tempering effect, readmission rate and the satisfaction degree were evaluated between the two groups one year later. Results A significant difference was observed between the two groups′ compliance (t=11.08, P<0.01), with the experimental group graded 69.27 ± 8.02 and the control group graded 48.76 ± 7.51. Moreover, in the experimental group, the angel of abduction, anteflexion, rear protraction, medial rotation, lateral rotation were respectively (170.13 ± 3.16)° , (172.45 ± 1.94)° , (46.71 ± 1.86)° , (81.30 ± 2.47)° and (85.18 ± 1.55)° ,which were significantly higher than the control group (125.16±1.93)°, (136.28±4.67)°, (34.63±2.68)°,(61.59±1.71)° and(85.18 ± 1.55)° (t=22.74-73.76,P<0.01). Further more, there were also remarkable differences (χ2=32.97, 54.21, 15.34, P<0.05) between the two groups on the consultative, readmission and the satisfaction degree, which in the experimental group were 91.67% (110/120), 81.67% (98/120), 96.67%(116/120), and in the control group were 55.83% (67/120), 47.50% (57/120), 84.17% (101/120). Conclusions The establishment of the fans club informatization remarkably improves the self-management of the breast cancer patients, which are worth popularizing.

Objective To explore a simple and effective method of culturing primary human bronchial epithelial cells.Methods Bronchial epithelial cells were obtained from human bronchial tissues obtained from lobectomy or pneumectomy.Epithelial cells were isolated by three methods as fellows:1.proteinase XIV digestion with mechanical scraping,2.proteinase XIV digestion with mechanical stripping,and 3.trypsin digestion with mechanical scraping.Subsequently the cells were cultured in serum-free hormone-supplemented DMEM/F12.The quantity,purity and viability of cells isolated by three methods were compared.The cultured cells were identified with cytokeratins AE1/AE3 by immunohistochemistry.Results The quantity of cells [(9.37?1.62)?105] obtained from proteinase XIV digestion with mechanical scraping was significantly higher than that of proteinase XIV digestion with mechanical stripping [(5.20?0.75)?105](P

Objective To analyse CT appearances of fibroma and fibrosarcoma and to provide evidences for clinical diagnosis and treatment.Methods 8 cases with surgically-and pathologically-proved hard fibroma(nasal cavity,maxillary sinus and soft palate each and all 2 cases)and fibrosarcoma(nasal cavity and maxillary sinus each and all 1 case)were studied with retrospectively analysis.The scanning parameters were 5 mm thickness and interval for axial scanning.Results CT appearances of fibroma were single circular,semicircular or elliptical soft tissue masses which usually had homogeneous density,clear margin,thin and full envelope,wide base or a pedicel and slight or middle enhancement after contrast.The tumors grew distensibly,bones near the mass were constricted and thinned or absorbed but never destroried and the structures nearby were deviated but not involved.Fibrosarcoma showed such common CT manifestations as other malignant tumors in the same locations.Conclusion CT appearances of fibroma has some features,they are different from more common benign lesions.Fibrosarcoma can not be differeciated from other maglinant tumors,thier diagnosis must depend on pathology.

Objective To evaluate the therapeutic effect of implantation of artificial urinary sphincter (AUS) for treatment of patients with trauma-induced genuine stress incontinence. Methods Two patients (1 male and 1 female) with genuine stress incontinence due to urethral rupture underwent implantation of AUS device (AMS 800).In the male case,the cuff of the AUS device was used to wrap the bulbar urethra.The reservoir was placed into the retropubic space.The controllable pump was implanted into the right scrotum. In the female case,the cuff was used to wrap the neck of bladder.The reservoir was placed into the retropubic space. The pump was implanted into the right subcutaneous labium majus.The literature was reviewed to show the indication,efficacy,complication and durability of implantation of AUS device. Results After operation the male patient was followed up for 17 months,and he achieved complete continence.The female was followed up for 14 months,and she had significant improvement in continence with changing 1 or 2 small pads every day.There were no infection, erosion, urethral atrophy and mechanical failure during follow-up.The review of the literature showed that in patients with implantation of AUS the mean of continence rate was 85.5%;the incidence rates of infection,erosion,urethral atrophy and mechanical failure were 6.1%,7.5%,6.1% and 16.7%,respectively. Conclusions The implantation of AUS is an effective,reliable method for patients with trauma-induced genuine stress incontinence.

Objective To investigate induction of the expression of human ?-defensin-2 (hBD-2) mRNA and the changes in activation of I-?B? and NF-?B by IL-1? in the human airway epithelium. Methods Primary human respiratory tract epithelium were stimulated with IL-1? and and/or PDTC. The expression of hBD-2 mRNA was detected by reverse transcription polymerase chain reaction (RT-PCR). The I-?B? protein level in the cytoplasm was determined by Western blot, and the nuclear factor-kappaB (NF-?B) binding activity was analyzed by electrophoretic mobility shift assays. Results The hBD-2 mRNA expression could be detected after 1.5 hours of IL-1? stimulation at concentration of 1?g/L, and the expression of HBD-2 was in a dose dependent manner. Stimulation with IL-1? resulted in a reduction of I-?B? protein levels. The supershifts assays indicated that the p65-p50 heterodimer complexes of NF-?B were involved in the activation of NF-?B. Conclusions I-?B? can induce the expression of HBD-2 mRNA in a dose dependent manner; the p65-p50 heterodimer complexes of NF-?B play an important role in the regulation of hBD-2 gene expression in response to IL-1?.

Hearts from eight adult dogs were perfused through both coronary arteries with methylmethacrylate. Small specimens cut out from the left ventricular wall were eroded in 50% HCL for 5-7 days. The replicas were studied under the SEM (S-450). The main results were outlined as follows: The subendocardial capillary plexus composed of varied shapes and orientation of meshes was present. The capillary network of the myocardial layers was consisted of many parallel capillaries and between them a variety of models of anastomoses, such as "H" "K" and "8" modes etc, were observed. In our findings, it was demonstrated that the arteriole and venule were distributed between the myocardial bundles and their direction was often perpendicular to the myocardial bundles. The postcapillary venules were poured into venule by the "ginger or turnip root" arrangement. The replicas of the Thebesian veins were proved in our specimens. The A-V shunting was not observed.

Uracil (I) (2,4-Diketo-pyrimidine) was isolated from the radix aconiti collected from Jiangyou region of Sichuan Province.The chemical structure of this principle was determined by elemental analysis,IR,UV,MS,'H and 13C-NMR spectral data. The experiments were made to study the effect of uracil (I) on the cardiac contractile force and beating rate of the isolated toad hearts in comparison with uracil (II) (artificial synthesis). The results indicated that the 5?mol/L of uracil (I) and uracil (II) both had the effect of increasing the amplitude of myocardial contraction (P0.05) at 3 and 5 min. When the concentration was increased to 10 and 20?mol/L, the amplitudes of myocardial contraction were more incremental and 3 min later,the estimated value of uracil (I) and uracil (II) to increase the amplitude of myocardial contraction by 50% approached to 4.17 and 4.68, respectively. As described above, uracil (I) is a new cardiotonic in Jiangyou Fuzi.
