Objective: This study was performed to evaluated the efficacy and safety of continuous infusional paclitaxel and 5-Fu as first-line chemotherapy in patients with advanced esophageal squamous cell cancer (ESCC). Methods: A total of 22 patients with advanced esophageal squamous cell cancer with no indications for surgery and radiation therapy, or recurrent patients were enrolled from October 2008 to November 2010. All were treated with PTX 20 $mg/m^2$ was administered through a 16 hours continuous intravenous infusion on days 1 to 3, 8 and 9. DDP 3.75 $mg/m^2$ was given on days 1 to 4 and 8 to 11, continuous infusional 5-FU over 24-hours on days 1 to 5 and 8 to 12 at a dose of 375 $mg/m^2$, and folacin 60 mg orally synchronized with 5-Fu. The treatment was repeated every 21 days for at least two cycles. Results: 22 cases of all enrolled patients could be evaluated for the effect of treatment: 2 cases were CR, 9 cases PR, 5 cases SD and 2 cases PD, giving an overall response rate of 68.2%(15/22). The median time to progression was 7.0 months. The adverse reactions related to chemotherapy were tolerable; the most common toxic effects were marrow depression, alopecia, and fatigue. Conclusion: Low-dose continuous infusional PTX over 16-hours and 5-fu over 24-hours is a promising regimen with good tolerability in treating patients with advanced esophageal squamous cell cancer.

Background and Aims: Scutellaria is one of the most popular traditional Chinese herbal remedies against various human diseases, including cancer. In this study, we examined the active effects of Scutellaria extract and its main flavonoid constituents on the proportion of side population cells within human multiple myeloma cell line RPMI8226 in vitro and explored the potential molecular mechanisms involved. Materials and Methods: The contents of flavonoids in ethanolic extract of Scutellaria baicalensis Georgi were determined using high performance liquid chromatography. The antiproliferative effect of the ethanolic extract on RPMI-8226 was determined by CCK assay. Apoptosis was measured by annexin combining with propidium iodide in a flow cytometer. Cell cycle analysis was performed by propidium iodide staining in combination with flow cytometry analysis. Hoechst 33342 exclusion assay was used for the identification of side population within RPMI8226 cells. The expression of ABCG2 protein was assessed by Western blotting assay. Results: The content of major flavonoids constitutents of Scutellaria extract was baicalin (10.2%), wogonoside (2.50%), baicalein (2.29%), and wogonin (0.99%), respectively. The crude Scutellaria extract did not show significant anti-proliferative effect, apoptosis induction and cell cycle arrest in RPMI-8226 within the concentrations of $1-75{\mu}g/mL$. However, the ethanolic extract, baicalein, wogonin and baicalin reduced the side population cells in RPMI-8226, and data showed that baicalein and wogonin had stronger inhibitory effects. Correspondingly, they also exhibited significant effects on decreasing the expression level of ABCG2 protein in RPMI-8226 in vitro. Conclusions: Our results for the first time demonstrated a novel mechanism of action for Scutellaria extract and its main active flavonoids, namely targeting SP cells by modulating the expression of ABCG2 protein. This study provides an insight for new therapeutic strategies targeting cancer stem cells of multiple myeloma.

Purpose: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients. Methods: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed. Results: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%). Conclusions: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.

Radix ranunculus temate saponins (RRTS), one of the main constituents extracted from the popular traditional Chinese medicine Radix Ranunculi ternati, has been reported to have various biological activities including anti-cancer effect. The aim of this study is to investigate the effect of RRTS on the cell proliferation and apoptosis in human gastric adenocarcinoma SGC-7901 cells. The data showed that exposure to RRTS for 24 h produced cytotoxic effects on SGC- 7901 cells in a dose-dependent manner (with an IC50 value of 21.22±2.76 μg/mL), which was accompanied by apoptosis induction (from 2.18±0.89% (control) to 63.72±13.16% (100 μg/mL)). Both the extrinsic or death receptor pathway and the intrinsic or mitochondrial pathway were involved in RRTS-induced apoptosis in SGC-7901 cells. Furthermore, apoptotic signaling induced by RRTS was amplified by cross-link between the two pathways via the signal-integrating protein Bid. In conclusion, our findings contribute to better understanding the molecular mechanism of RRTS’ effect on gastric cancer cells and form the basis of the therapeutic development of RRTS in treating gastric cancer in the future.

Two new flavone glycosides, giraldiin A and B, together with three known compounds, annulatin, myricetin 3-O-α-L-rhamnopyranoside and gallic acid, were isolated from the ethanol extract of the root of Pteroxygonum giraldii Damm. et Diels. The structures of giraldiin A and B are designated as 3'-(α-L-arabinopyranosyloxy)-4',5,5',7-tetrahydroxy-3-methoxyflavone and 4'-(β-D-glucopyranosyloxy)-5,5',7-trihydroxy-2',3-dimethoxyflavone, respectively,on the basis of detailed spectroscopic analyses. The free radical scavenging activity of giraldiin A was evaluated by decolouring spectrophotometry of pentamethine cyanine dye (Cy5) with Fe2+-H2O2 Fenton radical generating system. The results indicated the hydroxyl free radical scavenging activity of giraldiin A (ED50 = 23.7 nmol/mL) is higher than that of some known antioxidants such as rutin, puerarin, daidzein and 2,6-di-tertbutyl-4-methylphenol.

While China achieved the fastest economic growth in the world since it actively adopted market economy after its economic reform, it also saw increase in various crimes. There is very little research done on the Minis-try of public security of the people’s republic of China, but based on the previous research, the types of crimes can be summed up as following. Firstly, the crimes in China are becoming organized and are becoming a commercialized profession. Secondly, the Chinese crime organizations are covertly managing their fund circulations through 3rd party bank accounts and virtual accounts on the internet. Thirdly, every time a new type of industry emerges, a new type of crime exploiting the industry grows rapidly. Meanwhile, under the Chinese planned economy, the MPS had a major role on many components of social life in China. For example, the relationship among the MPS, the prosecutors and the court clearly shows that the MPS is relatively higher in status, and its authority is encroaching the Ministry of Civil Affairs of the People’s republic of China, China administration of Taxation, and China Administration of Industry and Commerce, and is in need for a change through a reform. Meanwhile, after achieving a rapid economic growth since the 1960’s (83.1%), South Korea ranked first in human rights protection and international policing cooperation in the “Crime Index for Country 2015 Mid-Year”. The authority of China’s MPS is a part of national administrative authority, which comes from the people. Therefore, one must consider whence the authority exercised by the MPS derives. Here are some problems of MPS identified in this research. Firstly, the Chinese MPS is inefficient in tasks that utilizes human resources within the jurisdiction. Secondly, it is difficult to communicate the information related to crimes collected by the MPS efficiently. Thirdly, the MPS has limited ability in cutting the criminal funds. Fourthly, the MPS fails to fully cooperate in criminal investigations. Fifthly, MPS demonstrates an incomplete cooperation in Crime prevention tasks. Therefore, to keep up with the rapidly grown economy, various discussions on the role of MPS and an inter-national cooperation on the safety of people will become necessary.

Two new flavone glycosides, giraldiin A and B, together with three known compounds, annulatin, myricetin 3-O-$\alpha$- L-rhamnopyranoside and gallic acid, were isolated from the ethanol extract of the root of Pteroxygonum giraldii Damm. et Diels. The structures of giraldiin A and B are designated as 3'-($\alpha$-L-arabinopyranosyloxy)-4',5,5',7- tetrahydroxy-3-methoxyflavone and 4'-($\beta$-D-glucopyranosyloxy)-5,5',7-trihydroxy-2',3-dimethoxyflavone, respectively, on the basis of detailed spectroscopic analyses. The free radical scavenging activity of giraldiin A was evaluated by decolouring spectrophotometry of pentamethine cyanine dye (Cy5) with $Fe^{2+}-H_2O_2$ Fenton radical generating system. The results indicated the hydroxyl free radical scavenging activity of giraldiin A (E$D_{50}$ = 23.7 nmol/mL) is higher than that of some known antioxidants such as rutin, puerarin, daidzein and 2,6-di-tertbutyl-4-methylphenol.
