Dear Editor, Synovial sarcoma （SS） is a rare malignant neoplasm in young adults？ It commonly arises around the major joints or tendon sheaths. Furthermore, it has been described in numerous locations unrelated to joint structures, such as the heart, kidney, prostate, etc., which may lead to a diagnosis pitfall. Here, we present an extremely rare case of primary SS originating in the spermatic cord.

Background Retinal pigment epithelial （RPE） cell is a monolayer of multifunctional cells between the retina and the choroid. Peroxynitrite （ONOO-） is known to induce toxicity on RPE cells. This study aimed to evaluate ONOO- induced expression of inducible nitric oxide synthase （iNOS） and complement 3 （C3） via Fas/FasL pathway in RPE cells and the values of puerarin as a therapeutic target for inhibiting the apoptosis of RPE cells. Methods RPE cells were obtained from eyes of C57BL/6 mice. RPE cells were divided into control, ONOO-and puerarin groups. Control group was treated with saline, ONOO-group was treated with ONOO-, and puerarin group was treated with puerarin after added with ONOO-. All changes were observered at 6, 12 and 24 hours after treatment. Western blotting analysis was used to determine the expression of nitrotyrosine （NT, the foot print of ONOO-） and C3; flow cytometry was used to determine the apoptosis of RPE cells. Immunohistochemistry and Western blotting were used to determine Fas/FasL signal transduction. Gene array analysis, reverse transcription polymerase chain reaction （RT-PCR） and Western blotting were used to determine the expression of iNOS mRNA and iNOS protein in RPE cells. Results There were minor expression of NT, C3, Fas/FasL and iNOS mRNA in control group, and strong expression of NT and C3 in ONOO- group, while in puerarin group weak expressions of NT and C3 were detected as time passed by （P 〈0.001）. Apoptosis of RPE cells occured and reached a higher level at 6 and 24 hours after addition of ONOO- respectively in ONOO- group, but delayed apoptosis in puerarin group （P 〈0.05）. Compared to control group, the expression of Fas/FasL was up-regulated in ONOO- group, but was down-regulated in puerarin group （P 〈0.001）. Similarly, the expressions of iNOS mRNA and iNOS protein in ONOO-group were up-regulated in ONOO- group, but down-regulated in puerarin group （P 〈0.001）. Conclusions ONOO- expresseion in RPE cells may constitute the n

The reduction kinetics of zinc calcine under a CO atmosphere was evaluated by isothermal reductive roasting in a temperature range of 600-800℃.The extent of reaction of zinc calcine was measured using thermogravimetry(TG),and the decomposition mechanism of zinc ferrite in zinc calcine was analyzed based on variations in the soluble zinc and ferrous *** results indicate that the reaction was controlled by the nucleation of the products,with an apparent activation energy of 65.28 k J/*** partial pressure of CO affected the reaction rate more strongly than the CO intensity(defined as PCO/(PCO+PCO2)).The generation rate of zinc oxide was higher than that of ferrous oxide;therefore,the nucleation of ferrous oxide is the rate-determining step of the reaction.

We report the effects of biventricular pacing in a patient with hypertrophic obstructive cardiomyopathy （HOCM） refractory to medical therapy. A 58-year-old man with HOCM had suffered from dyspnea, chest pain and palpitation for 5 years. Cardiac catheterization showed a left ventricular outflow tract （LVOT） gradient of 80 mmHg. He refused septal myomectomy and the septal ablation was not available. Based on intraoperative pressure measurements, he was implanted with biventricular pacing and LVOT gradient decreased to 10 mmHg. During the follow-up period of 6 months, the patient＇s symptoms were markedly improved. Biventricular pacing may be an alternative therapy for patients with HOCM.

The microstructure and magnetic properties of iron arsenide(FeAs) with coarse-grain and nanocrystalline structure were investigated. Coarse-grain FeAs was synthesized through high-energy ball milling and heat treatment. Nanocrystalline FeAs was obtained by ball milling of coarse-grain FeAs. The results suggest that the reduced grain size of FeAs(from >100 to 32.4 nm) is accompanied by the introduction of internal strains up to 0.568% with ball milling time from 0 to 32 h. The magnetic properties of FeAs show that the coercivity is reduced from 29.2 to 15.6 kA/m and the magnetization is increased over time of milling. The low coercivity is mainly due to the small grain size stemmed from ball milling, while the increase of magnetization is primarily caused by the change of lattice parameters of FeAs and the emergence of superparamagnetic phase at the same time.
