Objective To explore the reliability of patients' sensation of the need to urinate,and to investigate the optimal volume and duration of bladder filling and training method for the stability of bladder filling. Methods From 2014 to 2015,Fifty patients with pelvic tumor were divided into group A and group B,according to whether they had the history of diseases or surgery in the pelvis or urinary system. Both groups received training of the sensation of the need to urinate. The training required patients to drink a fixed volume of water every time they emptied the bladder. The bladder capacity was measured by a bladder scanner ( BladderScan BVI 9400) ,and a rating scale of the sensation of the need to urinate was completed at 30 min,45 min,1 h,and over 1 h when the patient sensed the limit for bladder capacity. The optimal volume and duration of bladder filling or optimal frequency for the training were explored. The paired t-test method was performed for the difference between the predictive value and the measured value,Pearson method was performed for correlation between the sensation of the need to urinate and the measured value. Results In the A and B groups,there was no significant difference between the predicted value and measured value ( A:predicted value and measured value P=0. 777,B:predicted value and measured value P=0. 061) ,suggesting that the measured value could be used to reflect the predictive value. Compared with group B,group A had a higher correlation between the sensation of the need to urinate and the measured value ( rA=0. 812, rB=0. 762).The correlation between the predictive value and the measured value became the highest at 45 min and 1 h ( r=0. 858 and 0. 916) ,and the corresponding bladder filling volume and score of the sensation of the need to urinate were 330-450 ml and 4-6,respectively. The correlation between the predictive value and the measured value increased with the frequency of the training ( r2=0. 914, r3=0. 917, r4=0. 930, r5=0. 951,r6=0. 962) . Conclusions Before radiotherapy,patients with pelvic tumor should received at least 4-6 rounds of the training of bladder filling. Patients should drink 800-1 400 ml of water every time they empty the bladder,and the optimal bladder filling volume and the reliable and stable sensation of the need to urinate will be achieved after 45 min-1 h. For the patients with the history of urinary system diseases or pelvic surgery,the bladder filling volume needs to be measured using a bladder scanner ( BladderScan BVI 9400) during the training before radiotherapy.

Objective To observe the characteristics of fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) in juvenile retinoschisis. Methods The photochromes of the ocular fudus of 7 cases (14 eyes) who were diagnosed as juvenile retinoschisis were taken, among whom, 5 (10 eyes) were examined by FFA, and 6 (12 eyes) by OCT. Results In 8 eyes with cystiform stellate maculopathy under ophtalmoscope, the result of FFA showed granular fluorescence in different density and shape without exact connection of the configuration between these granules and the cystlike maculopathy. In 2 eyes with pigment disorder in the macula under ophthalmoscope, blocky fluorescence was found in FFA. In 3 eyes with peripheral schisis, FFA discovered distorted and dilated retinal capillaries with different extent, and flecks of non-perfusion area. OCT images revealed thickening of the macular neuroepithelium with laminal seperation, and cystic low-reflect areas in the inner layer. Conclusions In juvenile retinoschisis, pigment proliferation and degeneration in the macular area could be found. Granular fluorescence and cystic low-reflect areas could be seen in FFA and OCT, respectively.

Each granule of 1 g contained an equivalent of 5.78 g raw drugs. Three times a day with 10 g for each; and patients in control group were treated with placebo consisting of hawthorn fruit and malt. The dosage and medication were the same as those in observation group. Both therapies were respectively administered in a treatment course of two months. Before and after the therapy course,the followed indexes were measured.① Assay of immunological function: The levels of IgG, IgA and IgM from blood serum were detected with simple agar diffusion.② Assay of Ag level in nucleolus organizer region (Ag-NORs): The ratios non-histone staining acidity non-histone vs core area (IS%) was calculated by staining the activating lymphocytes of the blood by silver staining technique with microscope image analysis technique. ③ Assay of pulmonary function: The pulmonary function was measured by Sensor Medics Ros System in all of the people with the levels of forced expiratory volume in first second (FEV1.0), mean maximu expiratory flow (MMEF), peak expiratory flow (PEF), once after and before treatment. The examination was repeated three times in order to obtain the peak number. The difference of the three examinations was within ±5%.MAIN OUTCOME MEASURES: Comparison of T lympholeukocyte subpopulation and pulmonary ventilation function in the patients before and after 1 course.RFSULTS: Data of totally 62 patients was entered the final analysis without any loss.① Comparison of pulmonary ventilation function of patients in the two groups before and after 1 course: FEV1.0, MMEF, PEF,and ratio of FEV1.0 and forced vital capacity (FEV1%) in observation group were significant higher than those before treatment (t=2.12-3.41,P ＜ 0.05-0.01), thoseindexes in observation group were higher than those in control group (t=2.54-3.17, P ＜ 0.05-0.01). ② Changes of T lymphocyte subgroups of patients in the two groups before and after 1 course:The levels of CD3+, CD4+, CD4+/CD8+ in observation group after 1 course were high.er than those before treatment (t=2.71-13.20, P ＜ 0.01), but the level of CD8+ was decreased as compared with that before treatment (t =8.63, P ＜ 0.01). The levels of CD3+, CD4+, CD4+/CD8+ in observation group were higher than those in control group (t=2.85-11.84, P ＜ 0.01), but the level of CD8+ was decreased as compared with that in control group (t =5.83, P ＜ 0.01).CONCLUSION: The bufei yishen granule can obviously improve the pulmonary ventilation function and immunological function of COPD patients,and its intervention is superior to that of placebo.

BACKGROUND: Degeneration and regeneration after peripheral nerve injury is a very complex pathophysiological process. It still needs to investigate the promotive effects of electric stimulation in neuranagenesis.OBJECTIVE: To compare the effect and result of percutaneous nerve-muscle electric stimulation therapy in peripheral neuranagenesis of different position.DESIGN: A case analysis based on patients.SETTING: Laboratory of neuroelectrophysiology and department of orthopedics of a medical university affiliated hospital.PARTICIPANTS: Totally 78 patients with peripheral neurologic impairment proved by clinical diagnosis and electromyogram(EMG) were selected from the patients with peripheral nerve injury visited or hospitalized by the Department of Neurology and Orthopedics, Affiliated Hospital of Ningxia Medical University between October 1999 and June 2003.METHODS: Cantana EMG was used. Totally 78 cases received percutaneous nerve-muscle electric stimulation (PNMES) therapy for the observation of the restoration of peripheral nerve function.
