Abstract
Objective: To study the clinicopathologic characteristics and risk factors of sarcoma arising in fibrous dysplasia. Methods: A total of 18 cases were collected from January 2008 to July 2018 in Shanghai Jiaotong University Affiliated Sixth People's Hospital. The characteristics and the histologic type were retrospectively reviewed. IBM SPSS 19 was used for statistical analysis. Results: The male to female ratio of patients with fibrodysplastic sarcomatosis was 1.57∶1.00. The age of onset ranged from 24 to 87 years (mean 49 years). The long bones, especially the femur, were most frequently involved. Nine cases were osteosarcomas, three cases were high grade sarcoma and six cases were low grade sarcoma. Logistic regression analysis showed that age was an independent risk factor for sarcomatous change, compared with polyostotic or recurrent cases. Value of Wals was 13.61 (P<0.05), and odds ratio was 12.82,95% confidence interval was 3.31-49.70. Conclusions: Fibrodysplasia sarcomatosis is clinically nonspecific and the risk of sarcomatous changes increases approximately 12-fold when age of onset of fibrous dysplasia is over 40 years.

Abstract
Objective: To investigate the molecular mechanism of oxaliplatin-induced chemotherapy-induced peripheral neuropathic pain (CIPNP). Methods: A total of 16 male Sprague-Dawley rats of specific pathogen-free grade were randomly divided into two groups: oxaliplatin experimental group (2.4 mg/kg oxaliplatin dissolved in 5.0% glucose solution, n=8) and control group (equal volume 5% glucose solution, n=8). The rat model of CIPNP was established by continuous administration with oxaliplatin. In addition, mechanical allodynia, thermal hyperalgesia and cold hyperalgesia were measured and compared between the two groups. To explore the molecular mechanism of oxaliplatin-induced CIPNP, the gene expression of dorsal root ganglia (DRG) from the rat model of CIPNP was analyzed using RNA sequencing (RNA-Seq). Results: Mechanical and thermal hypersensitivity was exhibited on day 7 and a stronger hypersensitivity was observed on day 14. A total of 20 152 genes were quantified by RNA-Seq, and 379 differentially expressed genes (DEGs) were obtained with absolute fold change cut-offs ≥ 2 and P value<0.05. There were 7 genes (Npy, Car3, Cdkn1a, Nts, Prc1, Ms4a7 and Ecel1) that were involved in peripheral nerve injury-related neuropathic pain. Gene ontology (GO) functional enrichment analyses indicated that the DEGs induced by oxaliplatin were involved in oxygen transport, cell division, intermediate, centromere, oxygen transporter activity, oxygen binding. Moreover, the result of Kyoto Encyclopedia of genes and genomes (KEGG) analyses highlighted that the DEGs induced by oxaliplatin were involved in malaria, African trypanosomiasis, primary immunodeficiency, peroxisome proliferator activated receptor (PPAR) signaling pathway. Conclusion: Oxaliplatin induces CIPNP via pain-related genes and signaling pathways.

Abstract
OBJECTIVE To evaluate the effect of oltipraz (OPZ) on isoproterenol-induced heart failure (HF) and heart function. We also explore the underlying molecular mechanism of OPZ. MATERIALS AND METHODS The rats were randomly divided into four groups, including normal control group, isoproterenol (ISO) group, ISO +100 mg/kg OPZ group, and OPZ group. Hemodynamic parameters, such as left-ventricular systolic pressure, were statistically analyzed. Besides, plasma levels of brain natriuretic peptide (BNP), pro-inflammatory cytokines and antioxidant markers were assessed by using enzyme-linked immunosorbent assay (ELISA). Moreover, histopathological examination was applied to assess the degree of cardiac interstitial fibrosis. RESULTS OPZ could statistically improve the hemodynamic parameters of the heart function, and could also obviously attenuate cardiac interstitial fibrosis in ISO-induced HF rats when compared with the ISO group. Besides, plasma level of BNP in ISO +100 mg/kg OPZ group dramatically decreased in comparison with that of ISO group. Moreover, compared with ISO group, OPZ treatment significantly reduced the levels of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). Moreover, OPZ treatment remarkably increased the levels of antioxidant markers such as superoxide dismutase (SOD) and glutathione peroxidase (GPx) in ISO-induced HF rats. CONCLUSIONS OPZ administration may provide experimental evidence for the possible effect of OPZ on isoproterenol-induced heart failure in rats. Moreover, OPZ administration may have potential utility for the treatment of heart failure.

Abstract
The development of a reliable PCR assay for genetic testing of spinocerebellar ataxia type 3. Touchdown PCR conditions were tested and different primer sets were evaluated with genomic DNA from blood sample of patients suffering from spinocerebellar ataxia type 3 (SCA3). An improved PCR assay was developed with a new set of primers and using the optimized touchdown PCR protocol. This new assay had been successfully employed in the screening of one identificated SCA3 family. Results from the present study document a simple and reliable PCR assay for genetic testing of SCA3. Strategies used in the present study may find applications in the optimization of PCR assay for triplet expansion with GC rich in the sequence context.

Abstract
To clarify the effect of early insulin therapy on nuclear factor kappaB (NFkappaB) pathway and inflammatory cytokine responses in the liver and skeletal muscle in type 2 diabetes. High-fat diet and low dose streptozotocin (STZ) induced diabetic rats were given NPH insulin or gliclazide for 3 weeks initiated at the 3rd day after STZ injection as early treatment and NPH for 3 weeks at 1 month as late treatment. Intraperitoneal glucose tolerance test (IPGTT) was performed at 3rd day after the end of treatment. Early interventions caused a decrease in glucose-insulin index in IPGTT, promoted glucose transporter 4 (Glut4) gene and protein expressions in muscle and reduced phosphoenolpyruvate carboxykinase (PEPCK) protein levels in the liver. There was an increase in inhibitor kappaB (IkappaBalpha) protein and a decrease in NFkappaB p65 DNA binding activity. A decreased level in mRNAs encoding tumor necrosis factor (TNF)alpha in the liver and muscle and interleukin (IL)-1beta in the liver were observed. Our results suggested that early insulin treatment inhibits NFkappaB activity and inflammatory cytokine responses in the liver and skeletal muscle that were involved in the amelioration of insulin resistance in type 2 diabetic rats.
