Objective To report the result of minimally invasive treatment of scaphoid non-union in soldiers. Methods Twenty-two soldiers 19 to 27 years of age were admitted for the treatment of non-union of fracture of scaphoid bone. The duration of non-union ranged from 11 to 54 months (average 16 months).All the non-union was located at the scaphoid waist, with a gap of 2 to 5 mm (average 2.5mm) as shown by radiological examination. Cyst-like changes occurred in 6 cases and displacement of the sclerotic fracture ends was found in 3 cases. Under local anethesia, a needle was inserted into the site of non-union under X-ray monitor, and 5-10 ml red bone marrow harvested from the iliac crest was injected into the site of non-union. The wrist was immobilized in functional position with elastic bandage or plaster of paris cast after the injection. Radiological follow-up was carried out every one month postoperatively. Bone marrow injection could be repeated 1 month later when necessary. Results Bone union was found in 19 cases 3-15 months (average 6 months ) after the operation. Non-union recurred in 3 patients in whom displacement of the sclerotic fracture ends was found. No complications, such as infection or joint stiffness, occurred. Conclusion Minimally invasive treatment of scaphoid non-union in soldiers can relieve pain, reduce the hospitalization days and cost, and the result is satisfactory.

Objective To investigate the effectiveness of femoral troehanter reconstruction and artificial femoral head replacement in treatment of unstable intertrochanterie fractures in the elderly pa- tients. Methods Femoral trochanter reconstruction and artificial femoral head replacement was done on 106 patients with unstable intertrochanterie fractures. There were 45 males and 61 females, at age range of 80-105 years (average 88 years). Most of patients slipt in the room and got fractured. According to the Evans classification, there were 31 patients with type ⅢA fractures, 45 with type ⅢB and 30 with type IV. We used 4 kinds of methods to reconstruct the fracturad imertrochanters : (1) shape of" ∞ " ten- sion band fixation after intertrochanterie fracture reduction;(2) wire loop fixation of the lesser troehanter around proximal femur;(3)defect within the femoral ealear was filled with bone cement and remodeled; (4) for patients with relative intact base of femoral neck, the intertrochanterie fracture was transformed in- to femoral neck fracture and the femoral ealear was fixed with femoral prosthesis stem. Results All the operations continued successfully, with duration of the operation for 45-70 minutes (average 55 minutes). No artificial femoral head dislocation occurred during hospitalization. Of all, 79 patients were followed up for 6-48 months (average 16 months). No Late loosening, dislocation or infections occurred, with total excellence rate of 87.3%. Conclusions For elderly patient with unstable intertrochanterie fractures, reconstruction of femoral intertrochant and artificial femoral head replacement can restore the proximal femoral anatomy, maintain stability of the hip joint and help early functional exeereise, as can reduce ease fatality rate and improve the quality of life.

Objective To explore the mechanism of percutaneous laser disc decompression (PLDD) for treating prolapse of intervertebral disc. Methods 15 rabbits were divided into 3 groups randomly: sham group, model group with PLDD treatment, model group without PLDD treatment. The nerve conduction velocity (NCV) of L6 nerve root and the activity of phospholipase A2 (PLA2) in the intervertebral disc of L5-6 were determined 2 weeks after the initial surgery. Results NCV in the group with PLDD was significantly faster than that in the group without PLDD (P<0.001); NCV in the group without PLDD was significantly lower than that in the sham group (P<0.001). The activity of PLA2 in the group with PLDD was significantly lower than that in the group without PLDD (P<0.001); The activity of PLA2 in the group without PLDD was significantly higher than that in the sham group (P<0.001). Conclusion The activity of PLA2 in the herniated discs is higher than that in normal discs, which result in NCV falls remarkably. The PLDD can reduces chemical factors such as PLA2.

OBJECTIVETo study the prevalence of epilepsy in Jinshan--a rural area of Shanghai and to provide data for development of protocol on prevention and therapy of epilepsy.

METHODSStratified cluster sampling was used in Zhujing town, Jinshan district, Shanghai in 2000. In a door to door survey, all inhabitants in the study area were interviewed on seizures using a standardized protocol to include all new cases with epilepsy.

RESULTSThe crude prevalence of epilepsy was 3.11 per thousand among the population size of 48,628 and the adjusted prevalence was 3.62 per thousand with 3.65 per thousand in male and 2.50 per thousand in female. The prevalence rates of males were more than that of females in both places. Two peaks of epilepsy prevalence in Jinshan district Shanghai were noticed: in the age groups of 10 - 30 years old and older than 60 years. The highest prevalence appeared in rural area was 3.70 per thousand, much higher than that 2.45 per thousand in town.

CONCLUSIONThe prevalence of epilepsy in this district was lower than that in other districts of China.

ObjectiveTo discuss the clinical application of the temporary balloon occlusion of the common iliac artery in the control of hemorrhage in the operations of the old pelvic fractures.Methods From January 2006 to June 2009,twelve patients (10 males,2 females; mean age 33.9 years) with old pelvic fractures of Tile C type were treated operatively.Three cases were treated with external fixator.Operative treatments were delayed for the treatment of the life-threatening visceral injuries in six nonunions and three malunions.A balloon catheter was placed through intravascular intervention in the common iliac artery of the affected side.The balloon catheter was infolded when the osteotomy was performed and the operations were undertaken under temporary and total occlusion of the common iliac artery.Osteotomies and internal fixations were performed in 12 cases.Decompressions of lumbosacral trunk were undertaken in 4 cases complicated with injuries of sciatic nerve.ResultsThe mean time of operations was 290 min(range,210-367min).The mean time of occlusions was 65 min (range,45-90 min).The loss of blood ranged from 700 ml to 2800 ml,with an average of 1833 ml.All cases were followed up for 12-48 months,with an average of 35 months.The mean time of bone healing was 20.6 weeks (range,16-24 weeks).No thrombosis of the common iliac artery and deep venous thrombosis of the lower extremity or ischemic necrosis happened.In the four cases complicated with injuries of sciatic nerve,three recovered partly and could walk with a crutch and one recovered completely and could walk normally.Two cases limped and other six cases could walk normally.ConclusionThe effect of temporary balloon catheter occlusion of common iliac artery is reliable.It drastically reduces hemorrhage during the operation and avoid the complications of selective arterial embolism and ligation and makes the operations of the old pelvic fractures more safer.

In recent years，with the change in lifestyle and social environment and the increase in pressure in both life and work，male fertility has decreased significantly in China，and the incidence of male infertility has increased year by year，which has brought great challenges to andrologists. Traditional Chinese medicine （TCM） has a definite curative effect in the treatment of male infertility and is widely applied in clinical practice. In order to clarify the role of TCM in different types and each stage of male infertility，the China Association of Chinese Medicine （CACM） invited outstanding young andrologists in the clinic of TCM and western medicine to discuss topics such as idiopathic oligospermia and teratospermia，abnormal semen liquefaction，varicocele，immune infertility，improving success ratio of assisted reproductive technology，and ameliorating depression or anxiety. They conducted in-depth discussions on the advantages，characteristics，disadvantages，diseases responding specifically，and advantageous aspects of TCM treatment. The causes of male infertility and related links of treatment were summarized. Due to the unclear etiology and complex pathogenesis of male infertility，western medicine cannot achieve a good curative effect，while TCM，taking the holistic view as the core，specializes in improving functional diseases and can correspond to multiple targets and factors，with comprehensive treatments such as internal treatment and external treatment. This study summarized the advantageous diseases and advantageous stages of TCM treatment alone and integrated TCM and western medicine treatment and put forward suggestions for the treatment of the diseases by TCM and western medicine in order to promote the therapeutic effects and advantages of TCM among andrologists，increase mutual learning and communication between TCM and western physicians，provide patients with excellent and personalized treatment plans in clinical practice，and improve the curative effect of male infertility and fertility of males in China.
