Objective To study the influence of edaravone on malondialdehyda(MDA)and expression of Hsp-70 and Bcl-2 in the perihematoma region in rats.Methods A total of 120 health male rats were randomly divided into false-operation group(n=20)、intracerebral hemorrhage(ICH)-therapy group(n=50)and ICH control group.Each group was further divided into 5 subgroups respectively according to 6 h、24 h、48 h、72 h and 5d after model creation.Cerebral hemorrhage model was duplicated with the method created by Fredrik.Brain water content and MDA were measured.Expression of Hsp-70 and Bcl-2 were assayed in each group with immunohistochemical method.Results Brain water content and MDA were lower in ICH-therapy group than those in control group(P

Objective To evaluate the clinical efficacy and safety of the Huhang Burn Liniment in the treatment of Ⅱ degree burn wounds.Methods 400 cases of Ⅱ[degree burn patients admitted to the 4 research centers were divided into two groups(n=200).The treatment group was treated with external Huhang Burn Liniment and the control group was treated with topical silver sulfadiazine silver paste.The wound healing,safety and effect of treatment were compared between two groups.Results The wound healing time in treatment group was significantly better than that of control group (P<0.05).Before treatment,there was no significant difference in bacterial infection rate and VAS score between two groups.After treatment,the bacterial infection rate and the degree of pain relief in the treatment group were significantly better than those in control group(P<0.05).The cure rate and total effective rate in treatment group were 84.0 % and 97.5 % respectively,while the control group were 72 % and 87 %,the difference were statistically significant (P<0.05).Conclusion The Huhang Burn Liniment can effectively promote wound healing,inhibit the growth of bacteria,it's safe and reliable.

Objective To explore the best time point for the ipsilateral hepatocellular apoptosis and the contralateraI hepatic hypertrophy after selective portal vein embolization(SPVE)in rabbit.Methods In a randomized study design,forty rabbits were divided into 5 groups with 8 rabbits per-group,including one as the control and the other 4 were treated with SPVE during open surgery.The rabbits were killed postoperatively,in 3,7,14,21 days respectively after the embolization.The hepatic lobes volume,the ipsilateral hepatocellular necrosis rates and apoptosis index,and liver functions were determined as well. Results In the treatment groups,the average amount of the right liver volumes decreased from 46.4 cm~3 preoperatively to 46.0,44.4,42.0,39.7 cm~3 in groups of 3,7,14,21 days postoperatively;meanwhile,the left liver volumes increased from 54.0 cm~3 preoperatively to 54.5,56.3,61.7,63.9 cm~3 respectively during 3, 7,14,21 days after the procedures.The rates of future remaining live volumes(FRLV)increased from 53.8% preoperatively to 54.2%,55.9%,59.0%,61.0% at 3,7,14,21 days postoperatively.The apoptosis indexes of hepatocells from group A to E were 8.1%,12.2%,19.4%,20.1%,14.2% respectively.Conclusions SPVE leads to atrophy of the ipsilateral hepatic lobe and hypertrophy of contralateral lobe,indicating that hepatocytes undergone apoptosis,rather than necrosis.The time point is 7 to 14 days.

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.

Objective To investigate the effect of β-elemene on SGC7901 gastric cancer cell line and the potential proteins involved. Methods Human SGC7901 gastric cancer cells were treated with different concentrations ofβ-elemene.Cell viability was assessed.A proteomic method,isobaric tags for relative and absolute quantitation (iTRAQ),was employed to detect the proteins altered by β-elemene.Protein expression was validated by Western blot.Results β-elemene inhibited the viability of SGC7901 gastric cancer cells in a dose-dependent manner.Altogether,147 upregulated proteins and 86 downregulated proteins were identified in response to β-elemene treatment in SGC7901 gastric cancer cell line.Among them,the expressions of p21-activated protein kinase-interacting protein 1 (PAK1IP1 ),Bcl-2-associated transcription factor 1 (BTF)and topoisomerase 2-alpha (TOPIIα)were validated by Western blot and the trends were consistent with iTRAQ results.Top pathways involved inβ-elemene treatment in SGC7901 gastric cancer cell line included ribosome signaling,peroxisome proliferator-activated receptors (PPARs)signaling pathway,regulation of actin cytoskeleton,phagosome,biosynthesis and metabolism of some amino acids.Conclusion Our results suggest a promising therapeutic role of β-elemene for gastric cancer.The differentially expressed proteins give us better insights into the potential mechanisms involved in gastric cancer treatment using β-elemene.

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

Objective To investigate the feasibility of ~1H-MR spectroscopy(~1H-MRS)imaging to quantitatively detect fatty liver.Methods Twenty patients with fatty liver and 11 healthy volunteers underwent plain CT scan,conventional MR imaging and ~1H-MRS analysis.The blood lipid and liver function were tested on the same day as the MR examination.~1H-MRS sequence measured the peaks of H_2O and lipid,and the areas under the peaks.The relative contents of the lipid compound were calculated,and compared with the results of CT scan and liver function tests.Results The CT values of the normal group and the fatty liver group were(59?9)HU and(24?11)HU respectively.On ~1H-MRS a protruding high H_2O peak and a flat low lipid peak were observed in the normal group,while the protruding high H_2O peak and a high lipid peak appeared in the fatty liver group.The values of lipid peak in the normal group and the fatty liver group were(0.05?0.01)?10~5,(0.70?0.24)?10~5 respectively(t=4.32,P0.05),the areas under the lipid peak were(1.36?0.73)?10~9、(2.35?1.15)?10~9 respectively(t=5.21,P0.05).Conclusion ~1 H-MRS imaging is feasible to quantitatively detect liver fat and is a non-invasive method for detecting early fatty liver.
