Twelve populations of Inula lineariifolia were used as materials to measure morphological characteristics, photosynthetic parameters and chemical constituents. It aims to provide a theoretical basis for germplasm resources evaluation. The results showed that I. lineariifolia had relatively rich morphological diversity, there were significant differences of morphological characteristics, photosynthetic parameters and chemical constituents among populations. There was positive correlation on morphological characteristics and P(n). Twelve populations were divided into three-type. The three populations of Xuyi, Mingguang and Fengyang were of narrower-longer leaf, bigger biomass,better photosynthetic and higher chemical constituents. Then they were classified for a similar group. It proved that the three populations were more suitable for cultivation and promotion.

Effects of different drying methods including sun drying, steamed, boiled, constant temperature drying (at 40, 50, 60 °C) on appearance, hardness, rehydration ratio, dry rate, moisture, total ash, extractive and polysaccharides contents were studied to provide the basis of standard processing method for Tulipa edulis bulbus. The results showed that the treatments of sun drying and 40 °C drying showed higher rehydration ratios, but lower dry rate, higher hardness, worse color, longer time and obvious distortion and shrinkage in comparison with other drying methods. The treatments of 60 °C constant temperature drying resulted in shorter drying time, lower water and higher polysaccharides content. Drying time is shorter and appearance quality is better in the treatment of steaming and boiling compared with other treatments, but the content of extractive and polysaccharides decreased significantly. The treatments of 50 °C constant temperature drying led to similar appearance quality of bulb to commercial bulb, and it resulted in lowest hardness and highest dry rate as well as higher rehydration ratio, extractive and polysaccharides content, moderate moisture and total ash contents among these treatments. Based on the results obtained, 50 °C constant temperature drying is the better way for the processing of T. edulis bulbus.

Objective To understand the status of drinking-water supply and the progress of waterimproving projects in drinking-water-borne endemic fluorosis areas in Henan,and to provide scientific data for related government departments to carry out prevention and surveillance plan for those areas.Methods Questionnaire survey was carried out in all the villages in drinking-water-borne endemic fluorosis areas in Henan in 2010.Each village was given one set of questionnaire.Results By the end of 2010,the total number of fluorosis villages in Henan was 25 434,among them 11 484 villages had been conducted water-improving projects,accounting for 45.15％.Currently,9267 water-improving projects worked properly,accounting for 36.4％(9267/25 434)of all villages surveyed,and 80.7％ (9267/11 484)villages had water-improving projects.The projects in 2217 villages do not work properly,accounting for 19.3％(2217/11 484) of all projects.There were 5832 water-imp.roving projects conducted amnog 2005-2010,accounting for 50.8％ (5832/11 484) of all water-improving projects.Among villages with no such projects,97.5％(15 769/16 167) of them used shallow groundwater,and in villages with water-improving projects,89.6％ (8303/9267) of them used deep groundwater as drinking-water supply.Conclusions After 2005,the water improving progress was significantly speed up in drinking-water-borne endemic fluorosis areas in Henan,but progress of the water improving projects is relatively slow due to changing and expanding of fluorosis areas.The government should increase investment and improve the proportion of waterimproving defluoridation.

Objective To identify the dynamic influence of antibiotics use on T helper cell(Th) 1/Th2 cytokine balance in neonatal rats in their early life.Methods Twenty-four newborn SD rats were randomly divided into 3 groups including 2dCef group,7dCef group and a control group (n =8).SD rats at 2 or 7 days of age were injected Cefotaxime sodium intraperitoneally for 3 consecutive days.The control group was injected the same amount of phosphate buffer saline.Serum and bronchoaveolar lavage fluid (BALF) samples were collected on 35 days old and diffe-rential cell count in BALF was done.Enzyme linked immunosorbent was used to detect the concentration of interleukin(IL)-12,interferon-γ(IFN-γ),IL-4 and IL-5 in serum and BALF,and real-time quantitative PCR was used to detect mRNA expression of those cytokines in lung tissues.Results The number of total cells,neutrophils,and lymphocytes in Cefotaxime treated on 2nd day after birth were significantly higher than those in the controls and 7th day group (F =93.78,15.84,7.36,all P ＜0.05).For Thl cytokines detection:the IL-12 secretion in BALF and serum and INF -γsecretion in BALF of the 2 antibiotic groups were lower than those in control group (F =26.53,12.95,47.18,all P ＜ 0.05),the decrease in 2dCef group were more obviously than 7dCef group [(127.72 ± 12.35) ng/L vs (198.15 ± 18.93) ng/L,(105.91±13.61) ng/Lvs (133.63 ±13.82) ng/L,(147.23 ±24.10) ng/Lvs (178.52±12.46) ng/L,all P ＜0.05].The mRNA expression of IL-12 in antibiotic groups were lower than those in control group (F =33.60,P ＜0.05),and the decrease in 2dCef group was more obvious than that in 7 dCef group (0.073 ± 0.023 vs 0.093 ± 0.028,P ＜0.05).For the Th2 cytokines:the IL-4 secretion concentration and mRNA expression in the 2 antibiotic groups were higher than those in the control group (BALF,serum and lung) (F =64.26,13.79,11.54,all P ＜ 0.05),the increase in 2dCef group was more obvious than that in 7dCef group[(103.65 ± 7.68) ng/L vs (82.04 ± 8.77) ng/L,(87.81 ± 4.72) ng/L vs (69.69 ± 7.79) ng/L,(0.067 ± 0.036) ng/L vs (0.051 ± 0.055),all P ＜ 0.05];however,no significant differences of IL-5 either mRNA or cytokine secretion being detected among these 3 groups (F =0.50,0.75,0.08,all P ＞ 0.05).Conclusions Antibiotic use during early time of neonate rats alters postnatal immune cells distribution in the lung and promotes the shift in cytokine balance towards a Th2 profile,and the earlier the antibiotic use,the more serious the impact.

Objective To identify the relationship between sorafenib's efficacy and its side effects in treatment of advanced renal cell carcinoma patients. Methods Fifty-one patients having measurable diseases were diagnosed with advanced renal cell carcinoma. Of whom, 26 patients were in stage T1Nx,0,1M1, 12 patients in stage T2Nx,0 M1, 8 patients in stage T3NxM1, 5 patients in stage T4NxM1. These 46 patients of T1 -T3 had their primary diseases removed, but the 5 T~ patients didn"t have their primary diseases removed. These 51 patients received oral sorafenib 400 mg Bid continual-ly and they had CT scan every two months to evaluate the progression. The dosage of sorafenib wasmodified according to efficacy and toxicity. Two patients changed the dosage to 200 mg Bid due to se-vere side effects. Sixteen patients increased the dosage to 600 mg Bid or 800 mg Bid. The response ofSorafenib and toxicities as well as their severity were recorded. The toxicity severity was graded ac-cording to National Cancer Institute Common Toxicity Criteria version 3.0. The efficacy was deter-mined by RECIST criteria. The efficacy and progression free survival (PFS) were recorded. The sta-tistics analysis was conducted between sorafenib's side effects and efficacy as well as their severity by multi-faetor Logistic regression. Results The rates of adverse events in the patients receiving oral sorafenib were hand-foot skin reaetion 68. 6% (35/51), diarrhea 39. 2% (20/51), rash 25. 5% (13/ 51), mucositis 23.5% (12/51), hypertension 17.6% (9/51), and myelosuppression 13. 7%(7/51). The response rate in the patients who had toxicity of grade 3-4 was 33.3%(12/36), and that in the patients who had slight toxicity was 12.0%(3/25). The rate of hand-foot skin reaction was higher than that of diarrhea, rash, mucositis, hypertension and bone marrow suppression (P<0.01). Sor-afenib's efficacy was eorrelated to rash and mueositis (P=0.048, 0.045 respectively). More grade 3 4 side effects occurred in the patients who would have better response to sorafenib (P=0.008). The median PFS was 15.0 months and PFS was not related to the toxicity and its severity. Conclusions It may help to predict the response for sorafenib's side effects and efficacy in the treatment of the patients with advaneed renal cell earcinoma.

Objective To analyze the effect and related factors of sorafenib in the treatment of metastatic renal cell carcinoma(MRCC), and identify the potential predictive factors of sorafenib re-sponse. Methods The data of 51 MRCC patients who received sorafenib therapy, with or without combination with interferon or chemotherapy were retrospectively reviewed. After two cycles of treat-ment, patients were evaluated for progression or response. Pearson Chi-square test and Logistic re-gression test were performed respectively as univariate and multivariate analyses of sorafenib response. Results The overall objective response rate was 29.4%(95% confidence interval 16.9% to 41.9%, with 1(2.0%) complete response and 14(27.4%) partial responses. Twenty-nine(56.9%) had stable disease, and 7 (13.7%) had progression disease (PD). Significant independent predictive factors asso-ciated with good response in multivariate analysis were lung metastasis only(P=0.021, HR=5.127). Conclusions Sorafenib is effective in MRCC patients. Lung metastasis only is predictive factor in mul-tivariate analysis for sorafenib response.

Objective To observe myocardial tolerance to ischemia/reperfusion (I/R) injury in rats after exposure to X-ray irradiation.Methods Twelve male rats were randomly divided into control group and radiation group.The rat model of radiation-induced heart disease was established in the radiation group by precordial irradiation with 20.0 Gy of 6 MV X-ray in a single fraction.At 14 days after model establishment,the Langendorff perfusion technique was performed in the two groups and the cardiac parameters including left ventricular developing pressure (LVDP),left ventricular end diastolic pressure (LVEDP),maximal rate of left ventricular pressure rise/fall (+/-LVdp/dtmax),and coronary flow (CF)were recorded.Myocardial infarct size after I/R was compared between the two groups by 2,3,5-triphenyltetrazolium chloride staining.Results After 30 minutes of ischemia and 60 minutes of reperfusion,the irradiation group had a significantly slower CF than the control group (5.64±0.35 vs.8.38±0.52 ml/min,P=0.002).Moreover,the irradiation group had substantially poorer recovery of cardiac function in isolated hearts compared with the control group,as shown by a significantly reduced LVDP (25.4±2.31 vs.52.76±2.76 mm Hg(1 mm Hg=0.133 kPa),P=0.000),significantly reduced+/-LVdp/dtmax(547.04±78.74 vs.1 100.05±83.35 mm Hg(1 mm Hg=0.133 kPa)/s,P=0.001;-408.81±56.74 vs-813.62±73.82mm Hg(1 mm Hg =0.133 kPa)/s,P=0.002),and a significantly increased LVEDP (85.29±4.61 vs.65.65±3.65 mm Hg (1 mm Hg =0.133 kPa),P=0.012).X-ray irradiation induced a significantly increased percentage of myocardial infarct size in rats (44.67％±0.95％ vs.30.46％±0.96％,P=0.000).Conclusions X-ray irradiation can induce coronary injury,reduce myocardial tolerance to I/R injury,and increase myocardial infarct size after I/R in rats.

MTT Colorimetric method is usually applied for measuring the living animal cell number. By changing the reaction temperature and the reaction time as well as the colorimetric wavelength, the improved MTT colorimetric method was established to count the living bacterial cell number. This new method was used to measure the living cell concentration in the process for culturing bacteria PBW1. The results measured by the improved MIT colorimetric method and dilute plate method are similar. Compared with other methods including the dilute plate method, the improved MTT colorimetric method has many advantages such as accuracy, quickness.
