Objective To investigate the clinical efficacy of acupuncture plus Jisheng Shenqi pills in treating patients with diabetic neurogenic bladder. Method Patients with diabetic neurogenic bladder were allocated, using a random number table, to treatment and control groups. The treatment group received acupuncture plus Jisheng Shenqi pills and the control group, oral administration of Western medicine. Both groups of patients were treated for four weeks as a course. Post-treatment clinical total efficacy rates, pre-treatment and post-treatment postvoid residual urine volumes, and adverse reactions during treatment were compared between the two groups. Result The total efficacy rate was higher in the treatment group (93.8%) than in the control group (68.8%) (P<0.05). The postvoid residual urine volume decreased significantly in both groups of patients after treatment compared with before (P<0.05). Post-treatment postvoid residual urine volume was lower in the treatment group than in the control group (P<0.05). The adverse reaction rate was lower in the treatment group than in the control group (P<0.05). Conclusion Acupuncture plus Jisheng Shenqi pills is remarkably effective in treating patients with diabetic neurogenic bladder. It can effectively decrease postvoid residual urine volume in the patients, has higher safety and is worthy of clinical popularization.

Objective To analyze and compare the effect of early minimally invasive surgical treatment and conventional treatment for patients with severe acute pancreatitis.Methods According to the including criteria,eight randomized-controlled trials of this topic were enrolled into the analysis.The detail about the trial design,characters of the subjects and results of the studies were reviewed and analyzed by using Revman 4.2 software.Results Compared with conventional treatment,early minimally invasive surgical treatment was associated with a significantly lower incidence of mortality(RR=0.35,95%CI:0.20～0.63,P

The foot overpronation is termed as pronation persisting more than 25%of stance phase in a walking cycle, which may re-sult from some antenatal or postnatal conditions. Overpronation would lead to abnormal alignment of ankle, knee, pelvis and spine, and re-sult in a set of syndromes of chronic pain. The Navicular Drop Test and the Foot Posture Index are often used as the assessment tools, how-ever, there are several empirical ways for clinic. Foot orthoses, special shoes, taping and training of muscle strength are effective on overpro-nation as well as chronic pain.

Objective: To evaluate the preventive effect of ephedrine on hypotension under spinal anesthesia in patients with different age. Methods: Sixty patients scheduled for spinal anesthesia were randomly allocated to four groups with 15 each. Group Ⅰ and Ⅱ were adult patients aged from 25 to 55 years old and group Ⅲ and Ⅳ were geratic aged patients of 6575 years old. Every patient received a fluid loading of 7ml/kg before spinal anesthesia. The ephedrine was administrated to group Ⅱ and IV patients in a dose of 10mg i v and 30 mg i m and same amount of normal saline was administrated to group Ⅰ and Ⅲ as soon as spinal anesthesia was performed. Results:Thirty patients in the placebo groups developed a maximal decrease in MAP exceeding 20%. Ten of these (2 in group Ⅰ and 8 in group Ⅲ ) developed a decrease in MAP exceeding 35% and required treatment. In aged groups, all patients in group Ⅲ had a decrease in MAP exceeding 20 %, 53 % of whom, the decrease exceeded 35 %. Conclusion:Prophylactic use of ephedrine is effective in the prevention of hypotension during spinal anesthesia, especially in aged patients.

Objective: To investigate the characteristics of brain laterality in patients with childhood onset schizophrenia. Methods: The study employed a dichotic Chinese word listening test(DL) as a chief measure and WISC-R as an assistant measure to examine 16 patients and 20 normal children as controls. Results: DL indicated that the patients differed from the controls in ear advantages and their performances were significantly poorer than the controls in left ear. The performances of the patients on WISC-R showed that their PIQ was significantly lower than VIQ. Conclusion:The patients with childhood onset schizophrenia differed from the controls in brain laterality. They might be involved with right hemisphere impairment.

AIM: To investigate the correlation between the left ventricular filling type and geometry modality and functional change of the left ventricle in patients with hypertension. METHODS: Systolic function indexes (FS and EF) and diastolic function indexes (E, A, EAT, EDT, E/A,IVRT) in 120 patients with hypertension were measured by two dimensional ultrasonography (2-DUS) and M-mode and Doppler ultrasound. RESULTS: A rate of 83.5% in patients with hypertension appeared assured plump and configuration changes of left ventricle, and a rate of 84% in patients with hypertension appeared abnormal left ventricular filling function. The morphologic indexes were significantly different clearly in different left ventricular filling types, and the filling indexes were also significantly different in diferent left ventricular shapes. CONCLUSION: IVRT is a more important index than other factors to decide the left ventricular filling function. LVMI plays more important role than other factors in the left ventricular filling function.

Objective To evaluate the effect of a biodegradable paclitaxel-eluting biliary stent on bile duct scar formation and biliary stricture by observing the healing process after stent placement in a porcine billiary model.Methods A novel biodegradable paclitaxel-eluting biliary polylactide stent was manufactured by immersion method.The efficacy of drug release for paclitaxel-eluting biliary stent was investigated by HPLC.Paclitaxel-eluting stent were surgically inserted in the bile duct of fifteen swines in experimental group while stent without paclitaxel were placed in other fifteen swines in control group.Animals were sacrificed after 1,3,6 months.The anastomic healing of the common bile duct was observed.The size of anastomosis was measured and compared between the two groups.Result A novel biodegradable paclitaxel-eluting biliary stent was manufactured.The total amount of paclitaxel released was about 281 pg (30.4％) over a month as determined with HPLC methods.There was no death,no leakage.The diameter of anastomosis in the experimental group was significantly larger than that in control group.Cholangiography did not show obvious bile duct dilatation in experimental group.Histologic examination showed less hyperplasia of the bile duct wall in the experimental group than that in control group.Conclusion Release of paclitaxel via a biodegradable stent relieves billiary stricture in porcine model and have no obvious negative influence on wound healing of the common bile duct.

BACKGROUND:Overtraining is a series of functional disorder or pathological state induced by continuous fatigue accumulation because exercise load and body function are incommensurate to each other. At present, commonly used methods for establishing rat models of overtraining included treadmil , swimming and climbing rod, but treadmil is comparatively accepted in the world.
OBJECTIVE:To establish the standard of overtraining rat model and to implement objective of model establishment by dynamical y monitoring biochemical indexes and observing behavioral changes.
METHODS:A total of 16 Sprague-Dawley rats were randomly assigned to model and blank control groups. The model group received movement training according to the plan. After adaptable feeding, training was performed, 6 days every week, with a rest of 1 day. Increasing intensity on treadmil was used. From the first week of training, the speed, gradient and running time were gradual y increased. However, the blank control group was conventional y fed, without any training.
RESULTS AND CONCLUSION:Behavior changes of the training rats were arisen after five weeks. Serum creatine kinase levels increased continuously in training process, and higher than basic levels at 5 weeks (P<0.01). Serum urea nitrogen levels persistently increased, and higher than basic levels at 3 weeks (P<0.05). Hemoglobin and serum testosterone levels increased and then decreased, and significantly lower than basic levels at 8 weeks (P<0.05). Behavioral y, overtraining appeared. Simultaneously, hemoglobin and serum testosterone levels were significantly lower than basic levels. Serum creatine kinase and serum urea nitrogen levels were significantly higher than basic levels. These results indicated that the body was in overtraining state. The standard of overtraining rat model was established in this study. The overtraining rat model was established according to the training program when the training was lasted for 8 weeks, the training speed was 30 m/min;every training time was 110 minutes, and the gradient was 15°.
