Objective In this study,we aimed at investigating the clinical,laboratory and management characteristics of adolescent-onset SLE patients compared with adult-onset SLE patients.Methods 470 fe- male patients with SLE were divided into two subgroups:adolescent-onset SLE patients and adult-onset SLE patients.The analyzed variables included clinical,laboratory parameters,damage index and outcome charac- teristics.Results In 470 female patients with SLE,there were 98(20.85%)adolescent-onset SLE patients. The following manifestations occurred more frequently in adolescent-onset SLE patients:malar rash,cutaneous vasculitis,proteinuria and abnormal liver function.Adolescent-onset SLE patients had more severe disease features and had significantly higher mean value of SLEDAI.Mortality was higher in adolescent-onset SLE pa- tients than aduh-onset SLE patients.Renal and blood system were the organs that most frequently involved. Conclusion Adolescent-onset SLE patients accounts for roughly 20.85% of all SLE cases.It is necessary to pay more attention to adolescent-onset SLE patients because the management for them is usually more difficult and the prognosis is usually poorer than aduh-onset SLE patients.

BACKGROUND:Percutaneous vertebraplasty is a new means for the treatment of vertebral compression fractures and bone metastases. The multiplaner reconstruction with digital substraction angiography (DSA)-Innova 3D plays an important role in guiding the percutaneous vertebraplasty puncture, which can effectively prevent the leakage of bone cement. OBJECTIVE:To explore the value of DSA-Innova 3D in the guidance of puncture of percutaneous vertebroplasty. METHODS:From March 2014 to September 2014, a total of 72 patients with 94 vertebras were selected for percutaneous vertebraplasty, of whom 36 (48 vertebras) with Innova 3D (experimentalgroup) and 36 (46 vertebras) without Innova 3D (control group). Spiral CT scan was performed in al patients to assess the distribution of bone cement. The imaging quality in the two groups was compared by Mann-Whitney U test. RESULTS AND CONCLUSION:CT showed bone cement leakage occurred in 7 of the 36 patients in the control group. Leakages were into the lumber disc in two cases, paravertebral space in two cases, vertebral pedicle in onecase or veins in two cases. However, only one case of bone cement leakage was observed in the experimental group. With the guidance of DSA-Innova 3D, the experimental group had signficantly lower leakage and fluoroscopic time than the control group (P < 0.05). The multiplaner reconstruction with DSA-Innova 3D plays an important role in guiding the percutaneous vertebraplasty puncture, thereby effectively reducing the leakage of bone cement.

Objective:To investigate the biological mechanism of the degeneration of cervical spine in cervical spondylosis(CS) by analyzing the alteration of bone matrix components.Methods:Twenty five degenerative cervical vertebra and 8 blood samples from CS cases were collected.The contents of hyaluronic acid(HA),laminin(LN),pro collagen Ⅲ,collagen Ⅳ were detected by radioimmunoassay.Calcium,phosphate and total protein levels were detected by automatic biochemical analyzer.Results:Ruling out the inference of blood, the contents of HA, LN, pro collagen Ⅲ and collagen Ⅳ were significantly lower in degenerated CS vertebra than in the control, so as the levels of calcium and phosphate. Conclusion:Bone matrix components are obviously decreased during the degeneration of cervical vertebra, resulting in the alleviation of bone tenacity and hardness. This may be one of the biological mechanisms of cervical vertebra degeneration and deterioration of cervical spine biomechanics.

Objective To investigate protective effects of dexmedetomidine on oxygen-glucose deprivation/reperfusion(OGD/R)-induced neuronal apoptosis.Methods SH-SY5Y cells were differentiated to neurons with ATRA and followed by TPA.According to the results of preliminary experiment, OGD/R modle was constructed by oxygen-glucose deprivation(OGD) for 12 h and reperfusion(R) for another 12 h.During the start of the OGD, neurons were immediately divided into six groups: group D0(0 μmol/L dexmedetomidine), group D1(0.1 μmol/L dexmedetomidine), group D2 (1 μmol/L dexmedetomidine), group D3 (10 μmol/L dexmedetomidine), group D4(100 μmol/L dexmedetomidine), group D5 (1 000 μmol/L dexmedetomidine).After reperfusion 12 h, the cell viability was evaluated by the method of MTT.The cellular apoptosis was observed by flow cytometry method.The protective effects of different concentration dexmedetomidine on OGD/R-induced neuronal apoptosis were investigated.Then in chosen the exact group having protective effects, endoplasmic reticulum stress specific protein mesencephalic astrocyte-derived neurotrophic factor (MANF) and pro-apoptotic protein Caspase-3 and CHOP were detected by Westernblot method.Results Compared with group D0, there was no difference on the cell viability and cellular apoptosis induced by OGD/R in groups D1 and D2, but a significant decrease and increase in groups D4 and D5 (P<0.01 or P<0.05).And only group D3 had a neuroprotective effect, significantly increased the cell viability and inhibited the apoptosis (P<0.01).Further studys found that group D3 significantly up-regulated ER stress specific protein MANF (P<0.01) and inhibited up-regulation of Caspase-3 and CHOP (P<0.01).Conclusion These data suggest that 10 μmol/L dexmedetomidine had neuroprotective effect on OGD/R-induced neuronal apoptosis and significantly increased cell viability.Our results also indicate that up-regulation of ER stress specific protein MANF and inhibition of CHOP and Caspase-3 by MANF are involved in the neuroprotective effects of Dexmedetomidine.

PurposeTo optimize the imaging parameters of clinical MRI scanner in rat pancreas imaging to improve the image quality and to provide better MRI image quality and more economical research method for imaging study of rat pancreas. Materials and Methods Twenty-four healthy male Wistar rats were randomly divided into the conventional sequence (CS) group, the adjustment sequence (AS) group and the optimization sequence (OS) group, with 8 rats in each group. The rats in the CS group were scanned with conventional parameters using a clinical MRI scanner. The principle of parameter adjustment was: parameters associated with T1WI or T2WI imaging quality (TR, TE, slice thickness, NEX, FOV and matrix) was set with four changes, and only one of the six parameters was changed in each scan, image quality was evaluated by two senior radiologists, the parameter corresponded the best image quality evaluated consistently by two radiologists were selected as the optimal imaging parameter, all the optimized parameters were set up step by step in this way which formed the imaging parameters in OS group. The pancreatic signal intensity and signal to noise ratio was compared between CS group and OS group after imaging.Results The optimized sequence parameters in clinical MRI scanner were listed below: T1WI sequence (M3D/FSPGR/15): TR 6 ms, TE 2.5 ms, slice thickness 2.0 mm, NEX 8, FOV 7 cm×7 cm, Matrix 120×120; T2WI sequence (FSE-XL/90): TR 4000 ms, TE 71 ms, slice thickness 2.0 mm, NEX 1, FOV 8 cm×8 cm, Matrix 192×160. The pancreatic SI in T1WI and T2WI sequence of the OS group were significantly higher than those in the CS group (t=5.16 and 3.80,P<0.01), while the pancreatic SNR in T1WI and T2WI sequence of the OS group were significantly higher than those in the CS group (t=5.65 and 3.26,P<0.01).Conclusion The optimized parameters can improve the imaging quality of rat pancreas MRI significantly, thus provide a reference for the related experimental study.

OBJECTIVETo discuss the clinical effects and superiority of applying external fixation and bone transport to treat osteomyelitis and bone defect of femoral bone.

METHODSFrom August 2008 to December 2013,16 patients with osteomyelitis and bone defect of femoral bone were treated including 11 males and 5 females with an average age of 42 years old ranging from 13 to 62 years old. The average course of disease was 18 months ranging from 2 months to 4.5 years, and the average length of bone defect was 7.8 cm ranging from 4.5 to 15 cm. The bone defect of all cases were treated by external fixation and bone transport, the bone transport began at 1 week after operation, 1 mm per day and 4 times per day.

RESULTSAll patients were followed up for 10 to 36 months (means 22.5 months). One patient did not cooperate with treatment leads to the failure, then took the amputation. The remaining 15 cases of osteomyelitis were under control, including 12 cases of bone transport achieved one stage bone union, 3 cases achieved bone union via bone graft from iliac bone. The bone union time was 5 to 13 months(means 7.9 months). Thirteen patients almost obtained the same length of two lower extremities,2 patients had shortening of 1.5 to 2 cm. The time of moving the external fixation was from 6 to 16 months (means 9.3 months).

CONCLUSIONApplication of external fixation and bone transport is an effective method in treating the osteomyelitis and bone defect that can control the infection, eradicate wounds, and be the equalization of limb length.

OBJECTIVETo identify the correlation of the volume of residual urine (VRU) with the severity of bladder outlet obstruction (BOO) and detrusor contractility in patients with benign prostatic hyperplasia (BPH).

METHODSA total of 152 patients with clinically diagnosed BPH underwent ultrasonography for measurement of the prostate volume and RVU, free uroflowmetry, and urodynamic examination for the severity of BOO and detrusor contractility. Using the software SPSS20. 0, we analyzed the correlation between the ultrasonographic results and urodynamic parameters and compared the two sample means by the t-test.

RESULTSThe prostate volume was correlated positively with BOO severity (r = 0.432, P < 0.01) and detrusor contractility (r = 0.343 , P < 0.01) while Qmax negatively with BOO severity (r = 0.327, P < 0.01) but not significantly with detrusor contractility (r = 0.123, P > 0.05). VRU showed a significantly negative correlation with detrusor contractility when > 150 ml (r = -0.490, P < 0.01), even more significantly when > 300 ml (r = -0.717, P < 0.01), but exhibited no significant correlation with it when ≤ 150 ml (r = 0.041, P > 0.05).

CONCLUSIONVRU can somehow predict the detrusor function. For patients with VRU > 150 ml, especially for those with VRU > 300 ml, the detrusor function should be evaluated and urodynamic examination is recommended for exact assessment of BOO severity and detrusor contractility.

OBJECTIVETo investigate the impact of in utero exposure to di-n-butyl phthalate (DBP) on the apoptosis of testicular cells in the pubertal male rat offspring.

METHODSTen pregnant SD rats were randomly divided into a control and an experimental group to be treated intragastrically with olive oil (1 ml per day) and DBP (500 mg per kg of body weight per day) respectively between gestation days 12 and 19. At the pubertal age (postnatal day 45, PND 45), the testes of the male rat offspring were removed for observation of the cell structure under the transmission electron microscope and the development of different spermatogenetic cells by HE staining. The apoptosis of testicular cells was detected by the TUNEL method, the expressions of the apoptosis-regulating proteins Bcl-2, Bcl-XL, Bax and p53 were determined by immunohistochemistry and Western blot, and the data obtained were compared between the two groups by t-test.

RESULTSTransmission electron microscopy revealed increased apoptosis and vacuolization of testicular cells in the PND-45 rat offspring, HE staining showed markedly decreased numbers of different spermatogenetic cells, TUNEL manifested significantly increased apoptosis of testicular cells in the experimental group as compared with the control (12.00 ± 5. 22 vs 3.17 ± 1.47, P < 0.01), and immunohistochemistry and Western blot exhibited remarkably higher expressions of Bax and p53 in the former than in the latter group (P < 0.05).

CONCLUSIONIn utero exposure to DBP can increase the apoptosis of germ cells and Sertoli cells, induce the vacuolization of testicular cells, and significantly elevate the expressions of the apoptosis-promoting proteins Bax and p53 in the pubertal male rat offspring.
