OBJECTIVETo investigate the clinical effects of double-plating internal fixation for the treatment of medial tibial plateau fractures with fracture-dislocation type through combined anterior and inverted "L" posteromedial knee approaches.

METHODSFrom February 2010 to September 2013, 17 patients with medial tibial plateau fractures with fracture-dislocation type were treated by double-plating internal fixation at our department. Anterior knee approach was adopted for medial mass reduction and fixation,while the inverted "L" posteromedial approach was used for posteromedial mass. There were 11 males and 6 females, with an average age of 42 years old (ranged, 21 to 65 years old). The efficacy were investigated by comparing pre- and post-operative radiographic data, and by evaluating clinical symptoms using the HSS score system.

RESULTSAll the patients were followed with a mean time of 18 months (ranged, 11 to 25 months). The tibial-plateau varus angle immediately after operation and at the latest follow-up were respectively (87.8 ± 4.2)° and (88.2 ± 4.6)°, and there was no statistical difference (P = 0.458). The posterior slope angle immediately after operation and at the latest follow-up were respectively (10.1 ± 3.7)° and (10.3 ± 4.1)°, and there was no statistical difference (P = 0.512). The knee joint HSS score was 86.7 ± 6.1. No patient had complications such as infection, skin necrosis, internal fixation loosening or loss of fracture reduction.

CONCLUSIONDoubl-plating internal fixation through combined approaches is an ideal operation method for medial tibial plateau fractures with fracture-dislocation type, because it can provide clear surgical field, satisfactory reduction, reliable fixation, and chance for early functional exercise.

OBJECTIVETo observe the effect of Chinese herbal therapy on T-lymphocyte subsets in patients with IgA nephropathy (IgAN).

METHODSTotally 36 inpatients and outpatients at Department of Nephropathy, Xiyuan Hospital, China Academy of Chinese Medical Sciences, from June 2011 to June 2013 were recruited in the treatment group, while 20 volunteers were recruited as the healthy control group. Patients in the IgAN group only took Chinese herbal decoctions by syndrome typing for 3 months (except those accompanied with hypertension additionally took antihypertensive agents such as angiotensin-converting enzyme inhibitor and/or dihydropyridines calcium antagonist). No intervention was performed in the healthy control group. The values of Th1, Th2, and CD4+ CD25+ Treg, and red blood cell number in urine were detected using flow cytometry before and after treatment. 24 h urine protein was detected using inmmunoturbidimetry.

RESULTSCompared with the healthy control group, the CD4+ CD25+ Treg level obviously decreased in the IgAN group, showing statistical difference (P < 0.01). In the IgAN group, Th1, 24 h urine protein, and urine red blood cell counts were obviously lower after treatment, showing statistical difference when compared with before treatment (all P < 0.05).

CONCLUSIONChinese herbal therapy could reduce urine erythrocyte number and 24 h urine protein of IgAN patients, and down-regulating Th1 expression might be its mechanism.

OBJECTIVETo observe the clinical effect and safety of circumcision stapler in the treatment of phimosis and redundant prepuce.

METHODSWe treated 120 patients with redundant prepuce or phimosis using circumcision stapler and another 60 by conventional dorsal-incision circumcision. We observed intraoperative blood loss, operation time, postoperative pain, wound healing time, cosmetic appearance of the penis, and postoperative complications and compared them between the two groups of patients.

RESULTSStapler circumcision showed obvious advantages over the conventional method in intraoperative blood loss ([2. 3 ± 1. 3] vs [15.6 ± 2.9] ml), operation time ([7.1 ± 1.4] vs [22.6 ± 4.6] min), wound healing time ([12.0 ± 2.9] as [16.3 ± 3. 1] d), postoperative pain score (1. 9 ± 1. 3 vs 5. 2 ± 1. 7), incision edema, and cosmetic appearance of the penis (all P <0. 05). Besides, stapler circumcision exempted the patients from stitch-removal pain. However, the incidence rate of postoperative local ecchymosis was significantly higher in the circumcision stapler group than in the conventional circumcision group (20. 8% vs 8. 3% , P <0. 05).

CONCLUSIONCircumcision stapler, with its advantages of easier manipulation, shorter operation time, better cosmetic penile appearance, less pain, and fewer complications, is superior to conventional circumcision in the treatment of phimosis and redundant prepuce.

Objective To evaluate the advantages and short term clinical results of arthroscopic release with radiofrequeney vaporization for knee joint stiffness.Methods Arthroscopic release with ra- diofrequency vaporization was done in 32 cases with knee joint stiffness resulted from various causes be- tween January 2002 and June 2005.According to degree of stiffness,32 cases were divided into three groups,ie,Group A(18 cases with suprapatellar bursa adhesions)treated with confectioning at suprapa- tellar bursa and lateral grooves;Group B(eight cases with joint compartment adhesions)managed with debridement at suprapatellar bursa and lateral groove and intereondyloid fossa,bending the knee with pressure and abscising the adhesion part in the joint compartment with radiofrequency vaporization;and Group C(six cases with most part of the joint adhered)treated by making small incision at the lateral or medial upper pole of the patellar as well as a space at the suprapatellar bursa by blunt dissection when it was difficult to insert arthroscope.After that,release combined with massage manipulation and thorough hemostasis by radiofrequency vaporization were carried out.There was no drainage after operation.Pas- sive and active flexion and extension exercises with pressure began two days after operation.Results Pre-operative limitation of flexion was 35?-75?that was increased to 115?-125?three weeks after opera- tion,with mean improvement of 78?in Group A.Pre-operative limitation of flexion was 40?-60?that was increased to 95?-120?three weeks after operation,with mean improvement of 72?in Group B.Pre-opera- tive limitation of flexion was 25?-45?that was increased to 90?-110?three weeks after operation,with mean improvement of 64?in Group C.No haematocele occurred postoperatively,with only slight swelling of the knee.Conclusion Arthroscopic release with radiofrequency vaporization for knee joint stiffness is characterized by less bleeding,minor trauma and reliable release and can be applicable especially for the eases with only adhesion at suprapatellar bursa,lateral groove or joint compartment.

OBJECTIVETo analyze the intermediate-term results associated with the use of Zweymtiller hip system.

METHODSReview the 116 cases (142 hips) who were treated with total hip replacement from 1996 to 2002 by a single surgeon using cementless Zweymüller hip systems.

RESULTSSixty-one cases (77 hips) were followed up, 50 cases (64 hips) were evaluated both clinically and radiographically while 5 cases (6 hips) and 6 cases (7 hips) were only evaluated clinically and radiographically respectively. The average follow-up period was 7.3 years (range 5 to 11 years). The mean preoperative Harris Hip Score was 46 while the mean postoperative Harris Hip Score was 93. Distal cortical hypertrophy and medullary sclerosis were observed in 30 hips (42.3%) and 33 hips (46.5%) respectively. Heterotopic ossification arose in 45 hips (63.4%). Radiolucent lines occurred in 27 stems (38.0%) but in no cups. Radiolucent lines were mostly observed in Gruen zones 1. Osteolysis occurred in 7 cups (9.9%) and 18 stems (25.4%). Osteolysis was mostly observed in Delee Zone 3 and Gruen zone 7. In the distal Gruen zones 3, 4 and 5, no radiolucent line or osteolysis was observed. No hips had been revised, 3 cups needed revision surgery because of aseptic loosening.

CONCLUSIONThe 5-11 years follow-up results are satisfactory, but osteolysis is common.

OBJECTIVETo investigate the feasibility of treatment for calculous pyonephrosis with first stage percutaneous nephrolithotomy under the standard access.

METHODSThirty-six cases of calculous pyonephrosis and 36 cases of urolithiasis with no pyonephrosis were treated by percutaneous nephrolithotomy. In the nephrostomy, the caliber was dilated to F24. All the operations were preformed through the EMS lithotrity system. The intrapelvic pressure was detected in the operation. The hemoculture before and after operation, the germi culture of urine, and the temperature and blood leucocyte changes after operation were recorded. All the patients were treated by antibiotics before and after the operation.

RESULTSAll the patients were treated successfully. The average intrapelvic pressure were 23.2 cmH(2)O in non-pyonephrosis group and 22.8 cmH(2)O in pyonephrosis group. Both of the groups had 1 case of transient bacteremia after the operation. No significant difference was found in the other indices between the two groups.

CONCLUSIONEMS lithotrity system is safe and feasible for treating calculous pyonephrosis with stage I percutaneous nephrolithotomy via the standard access.

OBJECTIVETo study the pathogenesis of IgA nephropathy (IgAN) and the effect of Yiqi Zishen Granule (YZG) on the helper T-lymphocyte subsets Th1/Th2 in IgAN patients.

METHODSIntracellular cytokines secreted by Th1/Th2 were measured using flow cytometry in 24 healthy subjects and 31 IgAN patients treated by YZG before and after treatment.

RESULTSLevel of interferon-gamma (IFN-gamma) was lower (P < 0.05) and levels of interleukin 4 (IL-4) and interleukin 10 (IL-10) were higher (P < 0.01) in the IgAN patients than those in the healthy controls, showing imbalance of Th1/Th2 in the IgAN patients. After YZG treatment, the level of IFN-gamma increased and IL-10 level decreased (P < 0.01).

CONCLUSIONImbalance of Th1/Th2 exists in IgAN patients. YZG has a regulatory effect on imbalance of Th1/Th2 in IgAN patients.
