Objective To study the clinical efficacy of emergency early mechanical ventilation and bron -choalveolar lavage and drug intervention to severe asthma .Methods 140 cases with severe asthma were selected ,the patients were divided into the study group and the control group according to a random number table ,70 cases in each group,the control group were received early mechanical ventilation ,the study group were given bronchoalveolar lavage and interventional therapy on the basis of the control group ,clinical efficacy ,alveolar function ,her condition improved and hospital stay of the two groups were compared .Results The total efficiency of the study group were 92.9%(65/70) significantly higher than 81.4%(57/70) in the control group,the difference was statistically significant (χ2 =12.382,P<0.05);Forced expiratory volume in one second (FEV1),forced vital capacity (FVC) and FEV1/FVC of the study group were significantly better than that of the the control group ,the difference was statistically significant ( t=9.098,10.382,11.204,all P<0.05);Condition improved and hospital stay of the study group were significantly shorter than that of the control group,the difference was statistically significant (t=9.898,12.393,all P<0.05). Conclusion Emergency early mechanical ventilation and bronchoalveolar lavage and drug intervention to severe asthma had better clinical efficacy ,which can significantly improve the clinical symptoms of the patient .

BACKGROUND:The anesthesia process is required strict in establishing rabbit models of ileal neobladder. It is required for cleaning operation field, quick postoperative recovery, and the choice of anesthetics and anesthesia does not influence smooth muscle peristalsis. OBJECTIVE:To compare the anesthetic effects between urethane and chloral hydrate in rabbits with ileal neobladder. METHODS:Eighteen rabbits were randomly assigned to urethane and chloral hydrate groups, and were respectively anesthetized with 20% urethane 5 mL/kg and 10% chloral hydrate 2 mL/kg through the ear vein. Double ureter was dissociated at 1 cm outside original bladder, and 15 cm-intestine obtained from 10 cm of ileocecal junction was implanted so as to establish models of ileal neobladder. RESULTS AND CONCLUSION:Heart rates were significantly lower compared with these before anesthesia in al cases (P≤ 0.05), but no differences were detected between two groups (P > 0.05). Compared with the chloral hydrate group, the maintain time and recovery time were longer and the mortality rate was higher in the urethane group. Above data indicated that chloral hydrate is a safe long-acting anesthetic in establishing rabbit models of ileal neobladder.

Objective To study the effect of TGF?β1 gene therapy on the rat model of postpartum stress urinary incontinence and explore a novel non?operative treatment of this disease. Methods Two hundred and forty 6?month old SD female rats were used to prepare the model of postpartum stress urinary incontinence by vaginal dilation with a water sac. 148 rats from the 185 successfully prepared model rats were selected, and randomly divided into 5 groups: the TGF?β1 gene therapy, clentuterol treatment, electric stimulation therapy, injection of empty vector plasmid, and non?treated groups. In addition, 20 normal rats were selected as blank control group. Sneeze test and urodynamic test were conducted, the pelvic floor pubococcygeus muscle contractile force/muscle weight ratio was calculated, serum TGF?1 was detected by ELISA, and TGF?1 protein was detected by immunohistochemistry at 1, 21, 42 and 63 days after the treatment. Results At 21 days after treatment, all the maximum bladder capacity, leak point pressure, and urine or contractile force / muscle weight ratio of the TGF?β1 gene therapy group showed even better effects than those of the electrical stimulation group, but the differences were statistically not significant ( P>0?05 ) . Conclusions TGF?β1 gene therapy shows good therapeutic effect on the rat models of postpartum stress urinary incontinence, suggesting that TGF?β1 gene therapy may become a new type of non?surgical treatment for this disease.

This paper introduces the working principle of the blood circle treatment system outside the body. A monitoring instrument of plasma leakage suited for the blood circle treatment system outside the body is developed based on the absorption spectrum experiments of plasma leakage. Photoelectric detection technology and virtual instrumentation are utilized in the development. A series of detecting experiments of waste solution containing plasma with continuously changing concentration show the monitoring system possesses a relatively high sensitivity. Moreover, the experiments of continual detection with plasma concentration at one certain point indicate the monitoring system has a quite good stability. The monitoring instrument is adapted to dynamically detecting the plasma leakage when the blood circle treatment system outside the body is working.

Objective To study the effect of IGF-1 gene therapy and electric stimulation therapy on the rat models of postpartum stress urinary incontinence, and explore the ideal treatment for this disease.Methods 240 SD female rats were used to establish the model of postpartum stress urinary incontinence by water sac vaginal dilation.148 model rats were randomly selected from 185 successful models and divided into 5 groups:IGF-1 gene therapy, clenbuterol treatment, electric stimulation therapy, injection of empty vector plasmid, and untreated groups.Besides, 20 non-modeled rats were used as blank control group.Urodynamic test was performed, pelvic floor pubococcygeus muscle/muscle weight ratio was calculated, and serum biochemical indices (LDH, CK) were detected, and the morphological changes of pubococcygeus muscle fibers were observed by light microscopy at 1, 21, 42 and 63 days after treatment.Results At 21 days after treat-ment, the maximum bladder capacity, leak point pressure, the contractile force/muscle weight ratio in the IGF-1 group and electric stimulation treatment group were significantly better (P>0.05), and the differences between the IGF-1 group and electric stimulation group were not significant ( P>0.05 ) .Conclusions The effect of IGF-1 gene therapy and electric stimulation on the rat models of postpartum stress urinary incontinence is better than that in the drug therapy group and oth-er groups.

Objective To analyze the efficacy of electric sacral neuromdulation and resiniferatoxin in patients with female overactive bladder.Methods 32 cases with IOAB female patients accepted percutaneous test sitmulation of the electric sacral nerves at S3 ,and treated by intravesical instillation with 100ml of 100nmol/L RTX.The effica- cy of voiding status were evaluated.The improvement of female patients life were evaluated comparing the rating of depression and anxiety.Results There were significant improvements in 32 cases in variables included the number of voiding,volume voided and signs every day and urgent uresis.In the rating of depression and anxiety,the patients improved a litter and still had stimulating symptom in urethra and bladder.Conclusion The treatment of IOAB with single administratoon of electric sacral neuromdulation and resiniferatoxin is effective,and can successfully im- prove the symptom with little side effects.
