BACKGROUND: The strength and elasticity of general starch can be enhanced dramatically after plastic blends. The major characters of this material are magnitude molecular weight, many enwinded points, extreme containment of small molecules,and great gelation ability. It can be used as a biodegradable replacement of alginate. Furthermore, by adding osteoinductive factors, thermoplastics starch (TP) can be used as an organic engineering material, which can provide dual functions:anti-bleeding and bone formation. TP can also be used as intraoral tissue formation membrane and burn dressings.OBJECTIVE: To evaluate the bio-safety of TP through a cytotoxicity test.DESIGN: A controlled observation.SETTING: Beijing Research Institute of Traumatology and Orthopaedics; Beijing Jishuitan Hospital; Beijing University of Chemical Technology; Peking Univesity School of Stomatology.MATERIALS: The experiment was conducted at the laboratory of Beijing Research Institute of Traumatology and Orthopaedics from April to October in 2006. TP sample was obtained by plasticization of corn starch (12 wt % water content) with glycerol in a Haake Rhenmix at 110℃ and with 80 rounds per minute for 25 minutes, elongation at break from 115.3% to 245.3%. It was prepared by Beijing Key Laboratory for Preparation and Processing of Novel Polymeric Materials, Beijing University of Chemical Technology. Mouse fibroblast L-929 cell strain was provided by the cell bank of Peking University Health Science Center.METHODS: 1 × 107 L-1 cell aqueous suspension was cultured into leaching liquor ( 50% ), serving for TP group, and routine culture medium served for negative control group. Effect of TP on relative growth rate of L-929 cell strain was quantitatively measured by MTI" assay. The cytotoxicity of TP was evaluated according to GB/T16175-1996. Morphological changes and proliferation of cells were observed after2, 4, and 7 days of culture in the medium through an inverted phase contrast microscope.MAIN OUTCOME MEASURES: Cytotoxicity, morphological changes and proliferation of cells, and cell relative growth rate.RESULTS: Cytotoxicity: After 2 and 4 days of incubation, the absorbance (A) value was lower in the TP group than in the negative control group. After 7 days of incubation, the A value was significantly higher compared to negative control group (P＜0.01). It indicated that after 2 and 4 days of incubation, the cytotoxicity in the TP group was larger than in the negative control group, while after 7 days of incubation, it was on the opposite. All the test time, TP's cytotoxicity grade ranged from 0 to 1. Morphological change and proliferation of cells: After 2 days of incubation, both groups of cells were not extended to the outside of the scope, with a majority shape of being round, triangle, and quadrangle in the TP group or fusiform cells in the negative control respectively. Four days later, there were gaps among cells in the TP group, while in the negative control group, there were hardly any distance between cells and some cells piled up. Seven days later, cells in starch medium suddenly grew up to such a degree that all the cells lapped over and presented with more bloom than the negative control. Cell relative growth rate: After 2, 4, and 7 days of incubation, relative growth rate increased with time, being 85.63%,82.22%, and 113.05%, respectively.CONCLUSION: TP has no evidence of cytotoxicity and has good bio-safety.

OBJECTIVETo explore the concentration-response relationship between ambient concentration of PM2.5 and daily total hospital emergency room visits in Beijing during 2012 and 2013. This study also examined the effects of ambient PM2.5 during heavy polluted days on emergency room visits compared with the light polluted days.

METHODSWe collected the daily meteorological factors monitoring data and concentrations of air pollutants in Beijing during October 1, 2012 to December 31, 2013. We also collected the daily emergency room visits from a tertiary hospital in Beijing in the same time period. Generalized additive model was fitted to estimate the association between the ambient PM2.5 and the hospital emergency room visits, by using the smooth function to adjust long term trend of time, public holidays and day of week. In addition, constrained piecewise linear function was then used to estimate the excess risk for different segment of concentration-response function.

RESULTSThe annual average concentration of PM2.5 was 90.9 µg/m(3) during October 1, 2012 and December 31, 2013. There were total 64 260 cases for total emergency room visits, of which respiratory disease had 9 849 cases and cardiovascular disease had 11 168 cases. PM2.5 was positive related with PM10, NO2 and SO2. The corresponding correlation coefficients were 0.87, 0.78 and 0.62, respectively (P<0.05). And PM2.5 was positively related with relative humidity, with correlation coefficient 0.45 (P<0.05). But PM2.5 was negatively related with mean temperature (r=-0.17, P< 0.05) and wind speed (- 0.32, P<0.05). In the single polluted model, after adjusting the effects of temperature, relative humidity and wind, every 10 µg/m(3) increase of concentration of ambient PM2.5, the corresponding excess risk of daily emergency room visits was 0.25% (95% CI: 0.07-0.43). In the two-pollutant model PM2.5+SO2 and PM2.5+NO2, every 10 µg/m(3) increase of concentration of ambient PM2.5, the corresponding excess risk of daily emergency room visits were 1.07% (95%CI:0.83-1.30) and 0.56% (95%CI: 0.32-0.80) respectively, which were higher than the effect in single pollutant model. Average concentration of ambient particulate matters (PM2.5) was 204.16 µg/m(3) during heavy pollution, higher than control period (85.24 µg/m(3)). When PM2.5 as the primary air pollutants during heavy polluted days, we observed a significant increase in emergency room visits, and the odd ratios was 1.16 (95% CI:1.09-1.22).

CONCLUSIONThere were positive correlation between high concentration of ambient particulate matters (PM2.5) and increasing daily emergency room visits. Especially during the heavy polluted days, the effects of elevated concentration of PM2.5 on hospital emergency room visits were much larger.

Paclitaxel is the first-line chemotherapy drug for a variety of cancers. However， the paclitaxel resistance greatly reduced the efficacy in the later treatment stage， which seriously increased the mortality and recurrence rate of cancer and limited the clinical application of paclitaxel. At present， Chinese medicine compound prescription， proprietary Chinese medicine， and Chinese medicine injection are widely used as the adjuvant chemotherapy drugs for the treatment of cancer in clinic. Chinese medicine has shown unique advantages in improving the efficacy of chemotherapy drugs and the prognosis of chemotherapy， and reducing the toxic and side effects. However， the specific mechanism and effective monomer composition of Chinese medicine for reversing the resistance of chemotherapy drugs are unclear， and the application of Chinese medicine in different types of cancer is also limited， which are worthy of further exploration. This review summarized the composition of Chinese medicine monomer with synergistic antitumor effect combined with paclitaxel in recent years. The specific mechanism and pharmacological activities of Chinese medicine monomer reversing paclitaxel resistance were classified. This review found that through acting on the membrane transport protein， Chinese medicine monomer promoted the accumulation of paclitaxel in tumor cells， inhibited the expressions of protein and metabolic enzyme related to multidrug resistance and the metabolism of paclitaxel， and regulated the levels of apoptosis genes and factors and apoptosis-related pathways to promote the inhibitory effect of paclitaxel on cell proliferation. Chinese medicine monomer also significantly improved paclitaxel chemotherapy sensitivity by regulating the expression levels of micro ribonucleic acid （microRNA） and long non-coding ribonucleic acid RNA （lncRNA）， inhibiting the characteristics of tumor stem cells and tumor metabolic reprogramming， improving tumor microenvironment， and triggering tumor cell death autophagy and oxidative stress response. This review provides a theoretical basis for clarifying the specific anti-tumor mechanism of Chinese medicine monomer combined with paclitaxel， which is of great significance for the development of new Chinese medicine and the clinical research of the drugs combined with paclitaxel， and has certain value for the application of Chinese medicine combined with other chemotherapy drugs.

ABSTRACT: Meningiomas are the most common primary intracranial neoplasm with diverse pathological types and complicated clinical manifestations. The fifth edition of the WHO Classification of Tumors of the Central Nervous System (WHO CNS5), published in 2021, introduces major changes that advance the role of molecular diagnostics in meningiomas. To follow the revision of WHO CNS5, this expert consensus statement was formed jointly by the Group of Neuro-Oncology, Society of Neurosurgery, Chinese Medical Association together with neuropathologists and evidence-based experts. The consensus provides reference points to integrate key biomarkers into stratification and clinical decision making for meningioma patients.
