ObjectiveTo investigate the effects of infrared radiation and magnetic fields on the synovitis of rabbit with experimental knee osteoarthritis (OA).MethodsTwenty-four New Zealand grown rabbits were duplicated for OA model of the knee by extended fixation technique, and after 6 weeks, all rabbits were unchained from fixation. The rabbits were randomly divided into four groups: control group (no treatment), infrared group (treated with infrared radiation ), magnet-therapy group (treated with magnetic fields ) and the combined therapy group (treated with infrared radiation and magnetic fields). At the ends of the first, second and third week after treatment, 2 rabbits in each group were taken to measure the general change and histopathology of their synovium.ResultsCompared with other groups, the severity of synovitis (include the synovium line cells proliferation, the invading of granulation and blood vessels in the underlayer of synovium, the infiltration of inflammatory cells) declined significantly in combined therapy group. Scores of Ayral's index of combined group were significantly lower than other groups ( P<0.05), and there was no significant difference between infrared group and magnet-therapy group ( P>0.05).ConclusionThe combination of infrared radiation and magnetic fields can efficiently suppress the synovitis of OA and alleviate the tissue's destructions.

OBJECTIVE To study the antidepressant effects of ammoxetine(AMX)and the underlying mechanisms. METHODS Two behavioral despair models,the tail suspension test (TST) and the forced swimming test(FST),were used to evaluate the antidepressant-like effects of AMX 2.5-20 mg · kg-1 following oral administration. Monoamine neurotransmitter p-chloro-phenylalanine(p-CPA)andα-methyl-p-tyrosine(AMPT) depletion models in mice were used to investigate the effects of AMX on levels of 5-serotomin(5-HT)and norepinephrine(NE)in the brain. RESULLTS The results of behavioral study showed that compared with normal control group,AMX(10 and 20 mg · kg-1)reduced the immobility time of mice by 51.4% and 80.7% in the TST(P<0.05,P<0.01) or by 48.0% and 66.2% in the FST (P<0.05),respectively. Locomotion activity test indicated that AMX did not increase or decrease the movement distance of mice,demonstrating that AMX had no excitatory or inhibitory actions on the central nervous system. Moreover,AMX(5,10 and 20 mg·kg-1)exerted antidepressant effects in the p-CPA induced 5-HT depletion model and AMPT induced NE depletion model,as evidenced by the significantly reduced immobility time,ie,63.9%,93.4%,90.5% and 61.9%,77.2%,100% reduction in the TST (P<0.01),respectively,and AMX at the dose of 20 mg·kg-1 significantly increased the concentrations of 5-HT and NE by 144.7% and 57.2% in the mouse brain(P<0.05) ,respectively. CONCLUSION AMX has strong antidepressant-like effects in behavioral despair models and monoamine neurotransmitter depletion models in mice,which is involved in the increased levels of 5-HT and NE in the brain.

OBJECTIVETo review and summarize the experience of urethral reconstruction using lingual mucosal graft for the treatment of complex hypospadias.

METHODSWe evaluated the methods using lingual mucosal graft for the treatment of complex hypospadias. The dorsal inlay graft method and the tube graft method were used in our study.

RESULTSFrom Nov. 2010 to Oct. 2011,21 cases were treated. All the cases had at least one failed hypospadisa surgery before. The dorasl inlay grafting technique was used for 16 patients, the tube grafting technique was carried out in 5 patients(2 cases received Tube + Duply method). The follow-up period ranged from 3 months to 12 months (by average 6 months). The success rate of the methods was 61.9% with complications in 8 cases. Urethral fistula developed in 3 patients and urethral stricture developed in 5 patients. All cases who suffered stricture received the tube grafting technique. The fistula and urethral stricture were occurred at the site of the urethral termonoterminal anostomosis. Urethral stricture is the most common complication after the tube graft method for the treatment of the complex hypospadias.

CONCLUSIONSHarvesting the lingual mucosal graft is feasible and easy to perform. The complex hypospadias repair technique using lingual mucosal graft method provides good results. There fore it should be one of the preferred techniques for complex hypospadias repair. The dorsal inlay grafting technique has lower complication rate than the tube grafting technique. Early and regular urethral sounding should be carried out when patients received the tube graft method.

OBJECTIVETo observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.

METHODSTotally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.

RESULTSThe total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.

CONCLUSIONYHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.

OBJECTIVETo summarize the experience of urethral reconstruction using circular fasciocutaneous flap for the treatment of complex anterior urethral strictures.

METHODThe circular fasciocutaneous flap was harvested from the distal penile shaft or foreskin. Then the circular configuration was converted into longitudinal strip of skin which was rotated to ventral side to repair the exposured urethral strictures using the ventral onlay method. The surveillance protocol after urethroplasty was urination observation, regularly uroflowmetry and urethrography examination.

RESULTSFrom Nov. 2006 to Oct. 2012, 15 cases were treated. The mean age was 45 years (20-76 years) and mean follow-up period was 18 months(3 months-3 years). Stricture was caused by chronic urethritis in 4 cases, long-term urethral catheterization in 3 cases, transurethral perfusion chem other aphy in 3 cases, transurethral prostatectomy in 3 cases and hypospadias after surgery in 2 patients. The mean stricture length was 7.0 cm (3.5-12.0 cm). The overall success rate was 80.0% (12/15). Recurrence stenosis was noted in 2 cases and diverticulum formation in 1 case.

CONCLUSIONSThe penile circular fasciocutaneous flap can be used for anterior urethral stricture in nearly any length. The flap has the characteristics of hairless, adequate mobile and length, well-vascularized pedicle and easy to harvest. The onlay reconstruction provides excellent cosmetic results, less trauma, higher success rate. Therefore it should be one of the preferred techniques for complex anterior urethral stricture repair.
