Objective To assess sperm chromatin structure assay (SCSA) and sperm chromatin dispersion test (SCD) for DNA fragmentation evaluation in human infertility, and the correlation between these two methods. Methods We used SCSA and SCD assays to detect DNA fragmentation in sperm from 134 infertile men. The correlation of SCSA and SCD assays was analyzed. The sperm DNA fragmentation index (DFI) was divided into 3 groups (≤15%DFI, >15~≤30%DFI and>30%DFI), and the difference between SCSA and SCD assays was assessed. Results The SCSA assay was strongly correlated with the SCD assay for sperm DNA fragmentation (r=0.915, P<0.001). There was no significant difference between>15~ ≤30%DFI and>30%DFI groups. However, SCD showed higher levels of DNA fragmentation than that measured by SCSA for≤15%DFI group (13.50 4.82 vs 9.79 2.60, P<0.001). Conclusion There is a strong positive correlation between SCSA and SCD assays in detection of DNA fragmentation. SCD assay showed higher levels of DNA fragmentation than that measured by SCSA for≤15%DFI group.

Objective To investigate the clinical features,diagnosis and prognosis of solid pseudopapillary tumor of the pancreas(SPTP). Method The clinical data of SPTP cases that underwent surgical resection with a definitive histological diagnosis in Zhong Shan Hospital from 1999 to 2007 were retrospectively analyzed.Result There were 42 SPTP cases undergoing surgery in this period,including 37 females and 5 males:mean age was 37.6 years.Tumors located in the pancreatic head in 18 cases and in the body or tail in 24 cases.The most common symptom was abdominal discomfort(n=20),palpable mass (n=8).Preoperative diagnostic accuracy of MRI and CT were 93%and 31.8%,respectively.Ten cases underwent pancreaticoduodenectomy,20 cases received distal pancreatectomy,3 cases did spleen-preserving distal pancreatectomy.Tumors were simply enucleated in 8 cases.Average diameter of the tumors was 6.1 cm,34 lesions were solid,6 were solid-cystic,2 were cystic.The overall perioperative morbidity was 38.1%,10 cases developed postoperative pancreatic fistula.The mean follow-up time was 38.6 months.Except three cases that were lost to follow-up,all the other cases were alive.Four cases(2 cases had had tumor enucleation,2 had had distal pancreatectomy)developed hepatic metastases on 70、110、41、3 months after first surgery,respectively.A transarterial chemoembolization was employed in three cases,while right hemihepatectomy was performed in one case. Conclusion SPTP is an indolent tumor with low-grade biological aggressiveness.Patients had a favorable outcome after surgical treatment,but enucleation should be avoided.Patients with liver metastasis may benefit from chemoembolization and liver resection.

Objective Sirolimus ( SRL) is a potent immunosuppressive drug used to prevent acute allograft rejection after re-nal transplantation.Nevertheless, the occurrence of proteinuria has recently been recognized among patients treated with SRL-based therapy.The aim of this study was to investigate the therapeutic effect of tripterygium wilfordii hook F ( T II) on proteinuria caused by SRL in renal transplant recipients who were treated by trilogy immunosuppressive therapy of sirolimus combined with mycophenolate and hormone. Methods 52 recipients were divided into 2 groups randomly:TⅡgroup (n=27) and valsartan group (n=25).The TⅡgroup was administered 1 mg/kg/d, and the valsartan group 80-160 mg/d for consecutive 12 months.Based on primary trilogy immu-nosuppressive therapy of sirolimus combined with mycophenolate and hormone, the dosage of sirolimus was adjusted according to the target concentration 6-10 ng/ml( ELASA approach) and mycophenolate was administered 750 mg twice per day, adjusting dosage ac-cording to the mycophenolate AUC 0-12 level(35-45 mg· h/L).The evaluation of therapeutic effect includes: complete remission, proteinuria decreased by>50%; partial remission, proteinuria decreased by 20% to 50%; ineffective, proteinuria decreased by<20%. Results During the 12 month follow-up, the total effective rates in the TⅡgroup and the valsartan group were 95.2%and 86.7%respectively, in which the TⅡ group decreased more significantly (P<0.01).The total cholesterol level and triglyceride level in TⅡgroup were obviously lower than those in valsartan group(P<0.01). The total cholesterol level and triglyceride level in valsartan group increased ([6.60±0.2]mmol/L vs [7.11±1.13]mmol/L, [2.47± 1.48]mmol/L vs [2.49±0.32] mmol/L).The serum protein level in TⅡ group was obviously higher than that in valsartan group ([41.1±1.2]g/L vs [37.9±4.2]g/L, P<0.05).At 3 month, 6 month and 12 month follow-up, the average serum creatinine levels in TⅡgroup were obviously lower than those in valsartan group ([1.5±0.4]mg/dl vs [1.6±0.3]mg/dl, P<0.05), ([1.3±0.3]mg/dl vs [1.8±0.5]mg/dl, P<0.05), ([1.1±0.4]mg/dl vs [2.1±0.5]mg/dl, P<0.05).The incidence rate of adverse reaction in valsartan group was obviously greater compared with TⅡgroup( P<0.05) . Conclusion Both tripterygium wilfordii multiglycosides and valsar-tan can reduce proteinuria caused by SRL in renal transplant patients,while the application of TⅡhas more remarkable effect.

BACKGROUND:In clinic, monosegmental pedicle screw fixation via the fractured vertebrae is commonly used for the treatment of thoracolumbar fracture. Studies have confirmed that the spinal stability is strengthened through bilateral pedicle screw fixation via fractured vertebrae, but some studies suggest that monosegmental pedicle screw fixation via fractured vertebrae can increase the spinal stability, and the conclusion lacks of the supports of biomechanics.
OBJECTIVE:To evaluate the biomechanical properties of monosegmental pedicle screws fixation via fractured vertebrae for thoracolumbar fracture.
METHODS:Eight cadavers’ thoracolumbar specimens (T11-L3) were provided by the Department of Anatomy, Yangzhou University School of Medicine. Saw was used to transect 2/3 of the vertebrae in order to make complete experimental thoracolumbar specimens. Eight specimens were divided into two group;beyond-fractured vertebrae fixation group and monosegmental fixation via fracture vertebrae group. The specimens in the two groups were treated with adjacent vertebral four screw fixation beyond fractured vertebrae and adjacent vertebral four screw fixation+monosegmental pedicle screw fixation via fractured vertebrae respectively.
RESULTS AND CONCLUSION:After thoracolumbar fracture, the differences between beyond fractured vertebrae fixation and monosegmental pedicle screw fixation via fractured vertebrae were as fol ows:load-strain relationship 12%, load-displacement relationship 11%, strength 18%, axial rigidity 11%, torsional mechanical properties 11%and pul out test 1.8%, and there were no significant differences between two groups (P<0.05). The biomechanics performance of monosegmental pedicle screw fixation via fractured vertebrae was more superior to that of pedicle screw fixation beyond the fracture vertebra for thoracolumbar fracture.
