A dispute about the decreasing-price problem of traditional Chinese medicine (TCM) has recently arisen. This article analyzes the statistical data of 1995-2011 in China, the results showed that the main responsibility of expensive health care has no direct relationship with the drug price. The price index of TCM rose significantly slower than the medicine prices, the production margins of TCM affected by the material prices has been diminishing since 1995, continuous price reduction will further depress profits of the TCM industry. Considering the pros and cons of raw materials vary greatly in price, decreasing medicine price behavior will force enterprises to use inferior materials in order to maintain corporate profits. The results have the guiding meaning to medicine price management.

Objective To investigate the significance of galactose galectin-3(Galectin-3)and matrix metalloproteinase-2(MMP-2)expression in gliomas patients and thire role in process of gliomas' malignancy development. Methods Immunohistochemistry was used to detect Galectin-3 and MMP-2 protein expression in 5 normal brain tissue and 40 patients with different grade gliomas. According to positive cells number of Galectin-3,MMP-2 in tumor cells under a microscope,to determine the expression,and the positive index(LI)which came from the percentage of the positive cell number out of the total cell number was to expressed the number of positive cell. Results Galectin-3 and MMP-2 protein expression in normal brain tissue were negative. In glioma tissues,Galectin-3 was mainly expressed in the cytoplasm and membrane of tumor cells. In 23 glioma tissue withⅠor Ⅱ grade,9 cases(39. 13% )was positive and the LI values was(5. 65 ± 3. 47)% in terms of Galectin-3 expression. In Ⅲ,Ⅳ grade glioma specimens,the positive rate of Galectin-3 expression was 76. 47%(13 / 17), and LI value was(27. 88 ± 22. 13)% . The difference of Galectin-3 expression and LI value were significant between specimens with Ⅰ,Ⅱ grade and Ⅲ,Ⅳ significant( χ2 = 4. 101,t = 4. 105;P < 0. 05). In human gliomas,MMP-2 expression protein was mainly expressed in tumor cells and vascular basement membrane of the endothelial cell cytoplasm. In 23 glioma tissue with Ⅰor Ⅱ grade,9 cases(39. 13% )was positive and the LI values was(5. 91 ± 4. 78)% in terms of MMP-2 expression. In Ⅲ,Ⅳ grade glioma specimens,the positive rate of MMP-2 expression was 88. 24%(15 / 17),and LI value was(30. 06 ± 22. 94)% . The difference of MMP-2 expression was significant between specimens with Ⅰ,Ⅱ grade or Ⅲ,Ⅳ grade( χ2 = 7. 882,t = 4. 271;P< 0. 05). The linear correlation analysis showed that there was positively correlation between Galectin-3 and MMP-2 positive cells(r = 0. 800,P < 0. 05). Conclusion Galectin-3 and MMP-2 protein expression in Ⅰ,Ⅱgrade gliomas is significantly lower than those inⅢ,Ⅳ grade glioma,and they are positively related with the progress of malignant gliomas. Galectin-3 and MMP-2 protein can be used to evaluate or judge the malignant stage of human brain glioma.

OBJECTIVETo establish transgenic mouse models of familial amyotrophic lateral sclerosis (FALS) and identify the genotype of the first filial generation.

METHODSSix male B6SJL SOD1G93A/+ hemizygote mice were mated with 6 female B6SJLF1/J+/+ mice to produce the filial generation. The genomic DNA was extracted from the tail vein blood of the first filial generation mice and PCR was performed to amplify the hmSOD1 gene fragment. The genotype of the mice was determined by electrophoresis, and the PCR product was purified for further gene sequence analysis and detection of mutation loci.

RESULTSFifty-three progeny mice were born and the survival rate before ALS onset was 98% (52/53), and among the survived mice, the positivity rate for hmSOD1 gene was 44.2% (23/52). Electrophoresis result showed that the PCR product of 236 bp was consistent with the hmSOD1 gene fragment, and the sequence of the PCR product was identical with hmSOD1 gene sequence of G93A mutant.

CONCLUSIONTransgenic mouse models of ALS can be established in the first filial generation of male B6SJL SOD1G93A/+ mice mated with female B6SJLF1/J+/+. PCR technique can precisely identify the genotype of the filial generation.

OBJECTIVETo investigate the clinical significance of promoter methylation status of hPer3 gene in acute myeloid leukemia (AML) patients and the in vitro effect of decitabine (DCA) on AML cell lines HL-60 and U937.

METHODSThe promoter methylation status of hPer3 gene and mRNA expression levels in bone marrow of 206 AML and 40 iron deficiency anemia (IDA) patients (as control) were detected by methylation specific PCR (MS-PCR) and real-time PCR (RT-PCR). The HL-60 and U937 cell lines were treated with different concentrations of DCA for 48 and 72 h. The inhibition rates of cell proliferation were detected by methyl thiazolyl tetrazolium (MTT); the early apoptosis rates by staining with Annexin V and PI; the CD14 and CD11b expressions by flow cytometry (FCM); the promoter methylation status of hPer3 gene by MS-PCR; and the hPer3 mRNA expressions levels by RT-PCR.

RESULTSThe promoter methylation rates of hPer3 in newly diagnosed (ND) group, partial remission(PR) group, complete remission (CR) group, relapse (R) group and control group were 93.65% (59/63), 54.39% (31/57), 24.66% (18/73), 61.54% (8/13) and 0% (0/40), and the hPer3 mRNA expression levels were 0.19 ± 0.08, 6.28 ± 2.11, 52.76 ± 14.17, 8.18 ± 4.36, 75.03 ± 18.16, respectively. There was a significant statistic difference between any two group (P < 0.01) excepting for between PR and R group (P > 0.05). After DCA treatment, the promoter hypermethylation status of hPer3 was reduced and the mRNA and CD14, CD11b expression levels were up regulated in a dose dependent manner with an induction of cell apoptosis.

CONCLUSIONSPromotor methylation status and mRNA expression of hPer3 gene may be indicators for evaluating AML. DCA can induce the expression of hPer3 gene and cells apoptosis in AML.
