Objective Soft and hard channel minimally invasive interventions for patients with hypertensive intracerebral hemorrhage have been used for many years. A retrospective study was performed to evaluate the superiority of these two methods. Methods 122 patients with hypertensive intracerebral hemorrhage were included in this retrospective study, 64 cases in soft channel group and 58 cases in hard channel group. The clinical effects were compared; catheter retention time and complications of the minimally invasive surgery were also observed in these two groups. Results In soft channel group, NIHSS before the treatment was 18.05±7.77, and NIHSS after the treatment was 7.57±4.68. The mortality was 17.19%. The catheter retention time in hematoma puncture was (4.35±1.56)days, and the catheter retention time in ventricle puncture was (7.67±2.37)days. There were 4 cases of rebleeding and 3 cases of intracranial infection. In hard channel group, NIHSS before the treatment was 18.38±9.02, and NIHSS after the treatment was 8.02±4.84. The mortality was 20.69%. The catheter retention time in hematoma puncture was (4.07±1.49)days, and the catheter retention time in ventricle puncture was (8.17±2.55)days. There were 9 cases of rebleeding and 2 cases of intracranial infection. The differences were not statistically significant (P＞0.05). Conclusions Soft and hard channel minimally invasive interventions of hypertensive cerebral hemorrhage have the same clinical value.

The fragmentation pathways of two taxanes drugs have been studied in positive ion mode by Q-TOF with the advantages of high mass accuracy and high resolution analysis. The [M+H] + ions were observed by ESI-MS, from which the molecular weights were obtained. Using the protonated pseudo-molecular ions [M+H]+ as internal reference compounds, the accurate mass and element composition of the fragment ions were determined. The collision induced dissociation (CID) data of the [M+H] ions provided fragmentation pathways of related compounds. Results showed that the major cleavage pathways of paclitaxel and docetaxel were the same that the cleavage of C-O bond between the side chain and taxol skeleton easily occurred, then stripping of the functional groups on the parent ring. Some common fragments were formed, such as m/z 105.033 7, 291.137 3, 309.148 5, 327.159 7, 387.181 2 and 509.217 4, which would provide a basis for future qualitative and quantitative analysis of taxanes in vitro and in vivo.

Objective To investigate the effects of essential trace elements selenium, zinc, copper, iron,cobalt, chromium and molybdenum upon arsenic poisoning caused by coal-burning. Methods Stratified random sampling method was used to conduct epidemiological investigation on 139 arsenic exposed residents(including nonpatient, light, moderate and severe patients) in an area polluted by coal-burning arsenic in Xingren county of Guizhou province as exposure group. Control group included 34 residents who lived about 13 km away from the endemic area of arsenic contamination. Inductively coupled plasma-optical emission spectrometry (ICP-OES) was used to analyze arsenic, selenium, zinc, copper, iron, cobalt, chromium and molybdenum in coal, soil, rice,corn, chilli, hair, blood and urine. Results Arsenic content in coal, soil, corn and chilli of polluted area were 4.894,146.551,0.522,1.440 mg/kg, respectively. These arsenic content were significantly higher than those in control area which were 1.980,50.167,0.296,0.948 mg/kg, respectively(P ＜ 0.05 or ＜ 0.01) . The content of selenium in soil of the diseased area(5.038 mg/kg) was significantly lower than that in soil of control area(8.948 mg/kg, P ＜0.05). The content of copper, iron, chromium in soil and iron in corn were 44.114,5731.500,98.323,89.996 mg/kg, respectively. These elements content were significantly higher than those in control area which were 13.473,1298.430,36.839,57.391 mg/kg, respectively (all P ＜ 0.05) . Hair and urine arsenic levels were 1.985mg/kg and 149.593 μg/g Cr in exposed group, respectively. These arsenic levels were significantly higher than those in control group which were 0.670 mg/kg and 49.853 μg/g Cr, respectively(all P ＜ 0.01) . Hair selenium level in exposed group(1.706 mg/kg) was significantly lower than that in control group(2.405 mg/kg, P ＜ 0.01). Hair levels of iron and chromium, blood level of eopper and the ratio between copper and zinc in exposed group were 88.295,8.933 mg/kg, 1.053 mg/L and 0.074, respectively. These element levels and elements ratio were significantly higher than those in control group which were 47.970,4.099 mg/kg, 0.934 mg/L and 0.065, respectively(P ＜ 0.01 or ＜ 0.05). Hair selenium level was negatively correlated with the progression of arsenism(r = - 0.414, P ＜ 0.01) .Hair levels of iron and chromium, the ratio between copper and zinc in blood were positively correlated with the progression of arsenism(r = 0.271,0.261,0.250, all P ＜ 0.01) . Conclusions Low selenium, high copper, high iron and high chromium coexists in arsenic polluted area. In exposed group, hair selenium is low, hair iron and chromium, blood copper and ratio between copper and zinc are high. These element changes with environment trend.These element changes are associated with the occurrence and development of the disease caused by coal-burning.

Objective To explore the influence of sodium selenite(Na2SeO3) and sodium phosphate(Na3PO4)given alone or combined on inhibition of liver cell proliferation of mouse exposed to sodium arsenite(NaAsO2) in vitro.Methods Primary mouse liver cell were treated with 8.0 μmol/L NaAsO2.Based on the two-factor and three-level (3 × 3) factorial design,the cells were randomly assigned into nine groups and cultured with different dosage of Na2SeO3(0.0,5.0,10.0 μmol/L) and Na3PO4(0.0,7.5,15.0 μmol/L),respectively.Liver cell activity was examined with thiazole blue reduction method (MTT) and the protective effect of Na2SeO3 and Na3PO4 on cell proliferation inhibition was tested.Results Different dose of Na2SeO3 had different protective effect on proliferation inhibition of mouse liver cell exposed to NaAsO2(F =35.743,P ＜ 0.05),so did Na3PO4(F =35.182,P ＜ 0.05).Meanwhile there was an interaction between Na2SeO3 and Na3PO4(F =13.702,P ＜ 0.05).The most significant intervention effect was observed in the group given low dose of Na2SeO3 (5.0 μmol/L) plus high dose of Na3PO4(15.0 μmol/L).Through pairwise comparison we found that there was no significant difference between the high and the low dose of Na3PO4 exposure groups of the protective effect on inhibiting of cell proliferation when the dosage of Na2SeO3 was fixed at certain levels(0.575 ± 0.070 vs 0.570 ± 0.017,0.789 ± 0.047 vs 0.797± 0.026,0.648 ± 0.027 vs 0.674 ±0.034,all P ＞ 0.05).However,when the dose of Na3PO4 was fixed,there was a significant difference between the high and the low dose of Na2SeO3 exposure groups(0.629 ± 0.026 vs 0.755 ± 0.063,0.789 ± 0.047 vs 0.648 ± 0.027,0.797 ± 0.026 vs 0.674 ± 0.034,all P ＜ 0.05).Conclusion A certain dose of Na2SeO3 and Na3PO4 has independent and combined antagonistic action to inhibition of mouse liver cell proliferation induced by NaAsO2 in vitro.

This study was aimed to investigate the genetic characteristics, identification method and transfusion strategy of rare blood type B(A). The rare blood group B(A) was typed by serological technique, PCR-SSP genotyping and sequencing of exon 6, 7 of ABO blood group. The genetic characteristics and molecular mechanism of B(A) blood group were also analyzed. Blood group compatibility test was conducted between blood donors of B(A) and recipients by clinical transfusion. The results showed that both forward and reverse grouping did not match the 3 cases of serological result in their family survey, while all of the 3 cases were grouped as AB blood group by forward grouping, B blood group by reverse grouping with serological result and B(A)04/001 group were genotyped by ABO genotyping. The patient of B blood group was transfused by 1 bag of washed red blood cells of donor of B(A) under closely monitoring, the patient's condition changed, and a mild adverse transfusion reaction was appeared. Washed red blood cell of O blood group was transfused into B(A) patient without blood transfusion reaction. It is concluded that the forward ABO serological grouping and reverse ABO serological grouping are not compatible, that may be verified by family survey and molecular biological methods. If in some cases transfusion therapy was applied, and group B(A) can not be transfused to the patient with group B or AB. Thus, transfusion compatibility or autologous transfusion can be adopted to transfuse to the patient from group B(A).

This study is designed to explore the possible effects of Hemerocallis citrina baroni flavonids (HCBF) on liver fibrosis induced by CCl4 in rats. The liver fibrosis model was induced by CCl4, and HCBF were administered by gastric perfusion at 25 and 50 mg x kg(-1) qd for 50 days, while the contents of alanine transaminase (ALT), aspartate aminotransferase (AST), gamma glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), superoxide dismutase (SOD), maleic dialdehyde (MDA) and transforming growth factor-β1 (TGF-β1) were measured and the contents of PINP were measured in liver tissue, and the expression of TGF-β1 were observed by immunohistochemisty and Western blot. The pathological changes of liver tissue were examined by HE. The results showed that HCBF (25, 50 mg x kg(-1)) improved the liver function significantly through reducing the level of ALT, AST, GGT and ALP (P < 0.05 or P < 0.01), and increasing the content of SOD (P < 0.01), while reducing the content of MDA (P < 0.05 or P < 0.01), the expression of TGF-β1 (P < 0.05) and the content of PINP (P < 0.05). The results suggest that HCBF (25, 50 mg x kg(-1)) may inhibit the liver injury induced by CCl4 by decreasing the oxidative stress.

OBJECTIVETo compare the Golgi proteome of hepatocellular carcinoma (HCC) with that of the adjacent non-tumor tissues.

METHODSHepatocellular carcinoma and adjacent non-tumor tissues were obtained from HCC patients. The protein expression maps in Golgi were obtained by two-dimensional gel electrophoresis (2-DE), and the differentially expressed protein spots were analyzed by PD-Quest software. Peptide mass fingerprint (PMF) of differential protein spots was obtained with MALD-TOT-MS.

RESULTSAccording to 2-DE maps, the average numbers of protein spots were (1153+/-49) and (1086+/-37) in hepatocellular carcinoma and the adjacent non-tumor tissues. Compared to the adjacent non-tumor tissues, 27 proteins were upregulated, and 20 proteins were downregulated in HCC Golgi.

CONCLUSIONSThe Golgi proteome in HCC tissues is different from that in the adjacent non-tumor tissues, and the differential expression proteins are involved in energy metabolism, tumor metastasis, and cell cycle regulation.

In the previous study, a high-throughput screening method was established to find the antagonists of CD36. In the present study, a new compound named IMB-1680 was found using this method. The anti-atherosclerotic activities of IMB-1680 were then evaluated. Dose-dependent activities of IMB-1680 were detected by using Sf9 [hCD36] and CHO [hCD36] models. Fluorescence microscopic photography and flow cytometry were used to analyze uptake of mLDL. Foam cell test with RAW264.7 macrophages was used to examine lipid accumulation. The results showed that IMB-1680 inhibited CD36 activity with IC50 of 2.80 and 8.79 micromol x L(-1) in Sf9[hCD36] and CHO [hCD36] cells, respectively. Fluorescence microscopic photography and flow cytometry revealed that IMB-1680 could significantly reduce DiI-AcLDL uptake. Meanwhile, IMB-1680 also could reduce lipids accumulation in RAW264.7 macrophages. In all, the data indicated that IMB-1680 might be a potent effective anti-atherosclerotic leading compound.
