Objective To explore the diagnosis value of cystatin C(Cyst-C) level on the renal function early impairment of Henoch-Schonlein purpura(HSP).Methods The selected serum creatinine(SCr) normal 45 sufferers,with measured their urine routine analysis,and the same time did serum Cyst-C.Compared with 30 healthy children of serum Cyst-C.Results The levels of serum Cyst-C in HSP were definitely higher than those in healthy group,and the differences were together with its signifincance(P

Aim To study clinical efficacy of valsartan,in comparison with amlodipine, in hypertentive patients with left ventricular hypertrophy. Methods 65 hypertentive patients with left ventricular hypertrophy is divided into two groups, with 33 cases in valsartan group and 32 cases in amlodipine group Valsartan 80～160mg and amlodipine 5～ 10 mg were taken by the patients in the two groups for 6 months respectively. 24 h ambulatory blood pressure monitoring ( 24 h ABPM) and color echocardiography were performed in the two groups before and after treatment. Results The parameters of 24 h ABPM ( 24 h SBP? 24 h DBP?dSBP?dDBP?nSBP?nDBP) and color echocardiography (IVST?PWT?LVMI)after treatment in the two groups were significant decreased compared with those before treatment respectively (P0.05). Conclusion Valsartan can lower significantly the blood pressure level and make left ventricular hypertrophy remarkably dispelled in hypertensive patients with left ventricular hypertrophy and has the effect similar to that of amlodipine.

Objective To detect genetic alterations in pleomorphic xanthoastrocytoma (PXA), and to investigate the mechanism of development of this neoplasm. Methods Three patients with PXA were studied. Comparative genomic hybridization (CGH) was performed to study chromosomal imbalances in PXA. Using immunohistochemical analysis, the expression of EGFR was detected in PXA. Results Using CGH analysis, genetic imbalance was detected on at least one chromosome for each case. One patient revealed multiple genetic alterations, including gains of 2p14-pter, 4p15-pter, 7p21-qter, 11q24-qter, 12 and 15q14-qter,as well as losses of 8p11.2-pter, 9p11-p23, 10p12-pter, and 13q14-qter. This patient experienced tumor recurrence and died one year later. Gain on Chromosome 7 and loss on Chromosome 8p were demonstrated in 2 of the 3 patients. Immunohistochemically, no EGFR positive reaction was found in all cases. Conclusion Detection of genetic alterations is very important in understanding the pathogenesis of PXA.

Objective To investigate the value of thyroid transcription factor-1(TTF-1) in the diagnosis and biological behavior assessment of hepatocellular carcinoma (HCC). Methods Thirty liver specimens obtained from benign lesions were analysed, among which 25 were hepatic cirrhosis and inflammatory diseases, and the other 5 were adenomas. And there were 176 specimens of liver tumors, among which 142 were HCC (well differentiated, n=12; moderately differentiated, n=57; poorly differentiated, n=73), 17 were intrahepatic cholangiocellular carcinoma (ICC) and the other 17 were liver metastatic carcinoma (MC). The expression of TTF-1 was examined immunohistochemically in the above tissues, and the difference in expression of TTF-1 among different tissues was examined by Fisher's exact test, Kruskal-Wallis test and Spearman rank correlation analysis. Results TTF-1 was significantly expressed in the cytoplasms of all the hepatocytes besides tumors and liver benign lesions. The expression rate of TTF-1 in HCC was 78.9% (112/142), however, TTF-1 was negatively expressed in ICC and MC(P

BACKGROUND:Denis B thoracolumbar burst fractures are common spinal injury and may be involved in the upper end plate injury. Fracture reduction and pedicle screw fixation are used to repair above injury. This scheme can effectively achieve the aim of correcting deformity, but the trabecular bone after crushing cannot be fuly recovered. OBJECTIVE:To observe the repair effect of fracture reduction and pedicle screw fixation + artificial bone graft in vertebral body on Denis B thoracolumbar burst fracture, and compare with fracture reduction and pedicle screw fixation alone. METHODS:Clinical data of 70 cases of Denis B thoracolumbar burst fractures, who were treated in the Department of Orthopedics, Zhangjiagang Aoyang Hospital from January 2012 to December 2014, were retrospectively analyzed. According to repair scheme, they were equaly divided into two groups. Patients in the control group received fracture reduction and pedicle screw fixation. Patients in the observation group received fracture reduction and pedicle screw fixation + artificial bone graft in vertebral body. Oswsetry Disability Index, height of anterior border of injured vertebral body, lower back pain visual analogue scale and vertebral kyphosis Cobb’s angle were compared and observed between the two groups before repair, 1 week, 3 and 6 months after repair. RESULTS AND CONCLUSION:No significant difference in Visual Analogue Scale was detected at 1 week, 3 and 6 months after repair between the observation and control groups (P > 0.05). Oswsetry Disability Index was significantly lower in the observation group than in the control group (P < 0.05). No significant difference in the height of anterior border of injured vertebral body was detected between the observation and control groups (P > 0.05). Cobb’s angle was significantly lower in the observation group than in the control group (P < 0.05). These findings suggest that fracture reduction and pedicle screw fixation + artificial bone graft in vertebral body obtained good repair effects on Denis B thoracolumbar burst fracture, not only effectively corrected Cobb’s angle and the height of anterior border of injured vertebral body, but also helped to restore normal spinal loads by filing bone in the injured vertebral body.
