Seventeen compounds derived from traditional Chinese medicines (TCMs) were tested for their antiviral activity against porcine reproductive and respiratory syndrome virus (PRRSV) in vitro. Visualization with the cytopathologic effect (CPE) assay and the 3-(4, 5-dimethyithiazol- 2-yl)-2,5-diphenyltetrazolium bromide test were used to determine the 50% cytotoxic concentration (CC50) and 50% effective concentration (EC50) in cultured Marc-145 cells. Among the tested compounds, chlorogenic acid and scutellarin showed potential anti-PRRSV activity. The EC50 values were 270.8 ± 14.6 μg/ml and 28.21 ± 26.0 μg/ml and the selectivity indexes were >5.54 and 35.5, respectively. The time-of-addition and virucidal assay indicated that the anti-PRRSV activity of the two compounds could be due to their inhibiting the early stage of virus replication and/or inactivating the virus directly. The inhibition of the virus attachment was not observed in the adsorption inhibition assay. The inhibition ratios of chlorogenic acid and scutellarin were, respectively, 90.8% and 61.1% at the maximum non-cytotoxic concentrations. The results have provided a basis for further exploration of their antiviral properties and mechanisms in vivo. We believe that the chlorogenic acid and scutellarin have a great potential to be developed as new anti-PRRSV drugs for clinical application.

The supervision of arbitration in the administration of justice is embodied in the following: confirmation of the validity of arbitration agreements, and the repeal and enforcement of arbitration awards. Both repeal and non-enforcement of arbitral awards are fundamental approaches of the courts` judicial review. In China, as well as in other countries, most of the arbitral awards are final and binding on the parties. However, there are several laws and regulations concerning the repeal and non-enforcement of arbitral awards, such as the Chinese Arbitration Law of 1995, and the Chinese Civil Procedure Law of 1991 (as amended in 2007). This paper not only introduces substantive provisions for repealing arbitral awards in general, but also outlines related procedural provisions on the basis of legislative development. Furthermore, it also points out the problems incurred by the Chinese legislation and analyzes this with reference to the New York Convention and other multinational legislation. Lastly, this paper proposes suggestions to solve these ongoing problems in the Chinese arbitration practice.
Progress on the Preparation of Ultra-pure Hydrogen Peroxide

Progress on the preparation of ultra-pure hydrogen peroxide is reviewed. The technologies include distillation and relative technologies, combination methods of ion exchange and adsorption resin, membrane separation and relative technologies, crystallization, flocculation, and adding addition agents as so well. Distillation is reliable and easy to industrialize, while purity of hydrogen peroxide distilled is not high enough. Crystallization, flocculation, and adding addition agents can only be used as accessory technologies. It is safe for membrane separation, but the life of membrane is short. Ion exchange and adsorption resin processes are simple and the product purity is high, but ion exchange resin is easy to be oxidized. It is the tendency for the preparation of ultra-pure hydrogen peroxide that distillation is used firstly and then the combination of membrane separation technologies or ion exchange and adsorption resin processes are followed.

Objectives. To show that mechanical compression of sigmoid sinus is effective for treatment of pulsatile tinnitus caused by sigmoid sinus enlargement, and to evaluate the relationship between the compression degree of sigmoid sinus and the tinnitus symptom relief using magnetic resonance angiography. Methods. Medical records of twenty-four patients who were diagnosed with venous tinnitus caused by sigmoid sinus enlargement and underwent mechanical compression of sigmoid sinus were reviewed between April 2009 and May 2013. All these patients received computed tomography and magnetic resonance venography study before undergoing surgery and were followed for at least 4 months. Results. Twenty-three patients felt relief from tinnitus three months after the surgery, and the cross-sectional area of the sigmoid sinus on the tinnitus side was compressed approximately by half (46%–69%) after the surgery. There were 4 patients whose tinnitus suddenly disappeared while lying on the operating table before operation, which may be a result of the patient’s emotional tension or postural changes from standing. One of the four patients felt no relief from tinnitus after the surgery, with the cross-sectional area of the sigmoid sinus only compressed by 30%. And two patients of them had a recurrence of tinnitus about 6 months after the surgery. Seven patients had sigmoid sinus diverticula, and tinnitus would not disappear merely by eliminating the diverticulum until by compressing the sigmoid sinus to certain degree. There were 3 minor complications, including aural fullness, head fullness and hyperacusis. The preoperative low frequency conductive and sensorineural hearing loss of 7 subjects subsided. Conclusion. Mechanical compression of sigmoid sinus is an effective treatment for pulsatile tinnitus caused by sigmoid sinus enlargement, even if it might be accompanied by sigmoid sinus diverticulum. A compression degree of sigmoid sinus about 54% is adequate for the relief of tinnitus symptom. Cases in which patients’ tinnitus suddenly disappeared before the surgery might be excluded to improve the efficacy of surgery.

The purpose of this research was to understand the successful establishment of the cultural industry chain in Korea and discover lessons for China to improve its cultural industry. It was concluded that a one-industry development pattern cannot win in market competition and a cultural industry will strengthen its sustainability only through smoothing its relationship with other industries and establishing a cultural industry chain so as to further development and resist crises together.

Background: A number of association studies have been carried out to investigate the relationship between genetic polymorphisms in DNA repair genes and response to radiotherapy-based multimodality treatment of patients with rectal cancer. However, their conclusions were inconsistent. The objective of the present study was to assess the role of DNA repair gene genetic polymorphisms in predicting genetic biomarkers of the response in rectal cancer patients treated with neoadjuvant chemoradiation. Materials and Methods: Studies were retrieved by searching the PubMed database, Cochrane Library, Embase, and ISI Web of Knowledge. We conducted a meta-analysis to evaluate the association between genetic polymorphisms and the response in rectal cancer treated with neoadjuvant chemoradiation by checking odds ratios (ORs) and 95% confidence intervals (CIs). Results: Data were extracted from 5 clinical studies for this meta-analysis. The results showed that XRCC1 RS25487, XRCC1 RS179978, XRCC3 RS861539, ERCC1 RS11615 and ERCC2 RS13181 were not associated with the response in the radiotherapy-based multimodality treatment of patients with rectal cancer (p>0.05). Conclusions: This study shows that DNA repair gene common genetic polymorphisms are not significantly correlated with the radiotherapy-based multimodality treatment in rectal cancer patients.
