Objective To explore the value of ureteroscopy in the diagnosis and treatment of ureteral injury caused by laparoscopic hysterectomy . Methods Suspect ureteral injury occurred in 23 cases out of 578 laparoscopic hysterectomy from January 2010 to December 2015 in our hospital.Among them, 12 cases were testified by ureteroscopy .A double-J catheter was placed in for 3 months. Results All the 12 cases were followed up for 3-26 months (average, 19 months).The double-J catheter was removed at 3 months after surgery .The continuity of the affected side urinary tract was restored in 10 cases and hydronephrosis was not found by B ultrasound .Two cases were found ureteral obstruction and were given ureterovesical reimplantation at 3 months after surgery . Conclusions The ureteroscopy should be carried out as early as possible for patients with suspect ureteral injury after laparoscopic hysterectomy .Double-J catheter placement can avoid parts of patients converting to open surgery .

BACKGROUND: Microwave had been widely used in medical field, which can lead to local coagulation necrosis and repair the necrosis with fibrous tissue. However, whether microwave coagulation can be used in stomatology is poorly understood.OBJECTIVE: To observe the functional and volumetric changes of skeletal muscles following microwave coagulation, and to explore the possibility of microwave coagulation for volumetric reduction of skeletal muscle.METHODS: Both sides of tibialis anterior muscle of 20 New Zealand rabbits were exposed; one side was coagulated by 2 450 MHz microwave therapeutic instrument at 70 W for 20 seconds. No treatment was performed at the other side. Rabbits were sacrificed at hours 24, 48, weeks 1 and 8 after microwave coagulation. The volumetric changes of the ablated tibialis anterior muscle were measured, and electricitic physiology observations were conducted on the ablated muscle at 8 weeks after microwave coagulation before being sacrificed.RESULTS AND CONCLUSION: The volume of ablated muscle increased at hours 24 and 48, which was (5.82±0.93) and (6.04±0.47) mL, especially greater at hour 48 after microwave coagulation. After 1 week, the muscle volume began to decrease to (4.90±0.80) mL, reduced to (4.27±0.67) mL at week 8, which was 23.6% volumetric loss. However, the electrophysiologic observation showed that the latent periods were (1.765+0.393) and (1.760±0.394) ms, and the wave width was (6.273±0.808)and (6.259±0.773) ms of the control group and experimental group, respectively, without apparent differences (P > 0.05). The volume of the skeleton muscle increased at hour 48 after microwave coagulation, and then decreased, but the muscle function of the skeleton muscle can be preserved.

Objective To study the effect of surface electromyogram-triggered electrical stimulation on lower limb function in hemiplegic stroke patients. Methods Thirty hemiplegic stroke patients were divided into a treatment group ( 15 cases) and a control group ( 15 cases). Both groups were given conventional rehabilitation training.Additionally, the treatment group was given surface electromyogram-triggered electrical stimulation training, while the control group was given common low frequency electrical stimulation. Brunnstrom's recovery stages, the Fugl-Meyer assessment (FMA) and electromyographic parameters were assessed before and after 3 courses of treatment. Results After treatment both groups had significantly higher Brunnstrom and FMA scores and better integrated electromyograms(iEMG), but the effects in the treatment group were significantly better than in the control group. Conclusions Surface electromyogram-triggered electrical stimulation training can provide satisfactory rehabilitation of lower limb function in hemiplegic stroke patients.

Objective To construct genetically engineered cells that secrete human TH and GDNF at the same time by stable co-transfection pcDNA3.0/hTH and pcDNA3.1/hGDNF in SH-SY5Y cells and study their effects on the gene therapy of Parkinson′s disease (PD). Methods pcDNA3.0/hTH and pcDNA3.1/hGDNF were constructed by inserting human TH and GDNF cDNA into pcDNA3.0 and pcDNA3.1, respectively. SH-SY5Y cells were transfected with pcDNA3.0/hTH and pcDNA3.1/hGDNF and the positive cell clones of human TH and GDNF cDNA engineered cells could be identified by RT-PCR. The engineered cells were co-cultured with primary dopaminergic neurons in mouse. The number and growth condition of primary dopaminergic neurons were examined by Immunocytochemistry. Results The number of primary dopaminergic neurons protected by double-gene engineered cells increased at least by 2.8 times in comparison with the control cells(P

Objective:To observe the morphological changes in skeletal muscles after therapeutic. Methods:Tibialis anterior muscles of 25 New Zealand rabbits were exposed and coagulated with 70 W for 20 s. The rabbits were sacrificed at 1 hour?24 hours?48 hours?1 week and 2 months after MCT. The specimens of coagulated areas were prepared for histological observation. Results:Obvious rims could be found bet ween coagulated and normal tissues .The ablated site showed tissue fixation in the inner zone and coagulative necrosis in found the outer zone.these were four zones can be seen under high powered magnification:the application zone,the central zone,the transition zone and the reference zone. Demarcation zone of necrosis appeared 24h after MCT. Tibrosis encapsulation occurred after 7 days.Replacement with fine cicatrix was demonstrated after 2 months. Conclusion:Tissue destroyed by coagulation can be replaced with a fine cicatrix gradually.
