The contents of adenosine, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxybenzaldehyde, parishin and sulfur dioxide residue were compared in differently-processed Gastrodiae Rhizoma to provide the basis for a reasonable processing method of Gastrodiae Rhizoma. The analysis was performed on a Merck Purospher STAR column (4.6 mm x 250 mm, 5 μm) with a mobile phase consisting of methanol and water (containing 0.1% formic acid) under gradient elution at a flow rate of 1.0 mL x min(-1). The eluates were detected at 270 nm, and the column temperature was 35°C. The content of adenosin, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxy-benzaldehyde and parishin in processing of boiling or sulfur-fumigated were lower than that of in processing of steaming. Furthermore, the sulfur dioxide residue of sulphur-fumigated groups exceed 400 mg x kg(-1). This stable and reliable method will contribute to the quality control of different processed Gastrodiae Rhizoma.

OBJECTIVETo identify the expression characteristics of the 1700001022RIK (RIKEN cDNA 1700001022) gene in mice and explore its function by bioinformatic analysis.
METHODSUsing the expression profile of gene microarray, we detected the expression of a new testis-specific gene, 1700001022RIK, in mice. We analyzed its expression characteristics in the testis tissue and their changes in different developmental stages of the testis by RT-PCR, real-time RT-PCR, Western blot, and immunohistochemistry. We performed bioinformatic analysis using a bioinformatic software.
RESULTSThe 1700001022RIK gene was specifically expressed in the mouse testis in an age-dependent manner, most highly in the adult mice. The 1700001022RIK protein was mainly expressed in the spermatogonia, spermatocytes, and round spermatids of the adult mice. Bioinformatic analysis showed that the 1700001022RIK protein amino acid sequence had a high similarity in human and mice, which indicated that this gene was highly conserved in mammals.
CONCLUSION1700001022RIK is a testis-specific gene mainly expressed in the spermatogonia, spermatocytes, and round spermatids of seminiferous tubules, which might be involved in the regulation of spermatogenesis.

Objective To observe the effect of high-frequency repetitive transcranial magnetic stimulation(rTMS)on hand function in patients after stroke. Methods From June,2016 to September,2017,30 stroke patients were randomly divided into control group(n=30)and experimental group(n=30).Both groups received routine training after sham rTMS or 3 Hz rTMS.Fugl-Meyer Assessment(FMA),modified Ashworth Scale(MAS)and modified Barthel Index(MBI)were used to evaluate the hand function and the activities of daily living before and after treatment. Results Finally 27 patients completed the experiment.After treatment, the FMA score increased in both groups (Z>2.070, P<0.05), and the difference value was higher in the experimental group than in the control group (Z=-2.296,P<0.05);the MAS score improved in the experimental group(Z=-2.456,P<0.05),no difference was found in the control group(Z=-0.816,P>0.05),and the difference value was higher in the experimental group than in the control group(Z=-2.792,P<0.01);the MBI score improved in both groups(t>3.085,P<0.01),howev-er,no difference was found in the MBI score and the difference value between two groups(t<0.246,P>0.05). Conclusion High-frequency rTMS could promote the hand function in patients after stroke.

OBJECTIVETo investigate the inhibitory effects of AP-1 decoy oligodeoxynucleotides (ODNs) on angiotensin II (AngII)-induced proliferation and collagen synthesis in neonatal rat cardiac fibroblasts (CFs).
METHODSThe CFs of neonatal SD rats were cultured in serum-free medium for 24 h and stimulated with 10(-7) mol/L AngII in the presence of AP-1 decoy ODNs or mutational AP-1 decoy ODNs at varied concentrations. MTT assay was employed for quantitative evaluation of the CF proliferation. Collagen synthesis in the CFs was assessed with hydroxyproline, and the cell cycle distribution determined with flow cytometry (FCM).
RESULTSWith the increase of the concentration of AP-1 decoy ODNs, the absorbance at 490 nm (OD490) of the CFs decreased gradually as shown by MTT assay. Treatment with 100 or 200 nmol/L AP-1 decoy ODNs resulted in significantly lowered OD490 of the CFs as compared with that of AngII group. The concentration of hydroxyproline increased significantly after treatment with 10(-7) mol/L AngII in comparison with the control group (P<0.05). Hydroxyproline concentration in cells treated with 100 or 200 nmol/L AP-1 decoy ODNs was significantly lower than that in the 10(-7) mol/L AngII-treated cells. AP-1 decoy ODNs decreased the cell percentage in S phase and increased hydroxyproline concentration, but increased the percentage of cells in G0/G1 phase. AP-1 decoy ODNs at 100 and 200 nmol/L did not obviously affect AngII-induced CF proliferation and collagen synthesis (P<0.01).
CONCLUSIONAP-1 decoy can inhibit AngII-induced rat CF proliferation and collagen synthesis possibly by affecting the cell cycle distribution.

OBJECTIVETo investigate the best dose and the long-term effect of the human insulin-like growth factor-1 (hIGF-1) gene injection into the penis of aged rats.
METHODSIncluded in this study were 10 young (4 months old) and 40 aged (24 months old) Sprague-Dawley male rats, the latter equally divided into a PBS control and a 10 microg, a 100 microg and a 1 000 microg hIGF-1 injection group. Electrical stimulation was conducted 4 and 8 weeks after hIGF-1 injection into the penile corpus cavernous of the rats to detect the intracavernous pressure (ICP) and mean arterial pressure (MAP). Dose - and time -associated therapeutic results were analyzed and the mRNA expression of hIGF-1 determined by RT - PCR.
RESULTSICP, MAP and total ICP were significant decreased by electrical stimulation in the aged rats as compared with the young ones (P < 0.05), statistically increased in the three hIGF-1 dose groups in comparison with the PBS controls (P < 0.05), and showed no obvious difference between the young rats and the latter two dose groups at 4 and 8 weeks. Although less obvious effect was achieved in the 10 microg group than in the young rats, the therapeutic result was still of significance. The mRNA expression of the hIGF-1 gene was confirmed in all the hIGF-1 treated rats.
CONCLUSIONThe hIGF-1 therapy can improve erectile function in aged rats, 100 microg suffices for effective erection and the effect may last at least 8 weeks for a single dose.

OBJECTIVETo observe the effect of Huxin Formula on expressions of the chief reverse cholesterol transport (RCT) associated genes, caveolin-1 and scavenger receptor-BI (SR-BI) in ApoE-gene knockout [ApoE (-/-)] mice.
METHODSThirty ApoE (-/-) mice of 4-6 weeks old were randomly divided into three groups (A-C). After being fed with high-fat diet for 16 weeks, they were treated with HXF (1 mL/100 g), pravachol (0.3 mg/100 g), and saline in equal volume respectively for 16 weeks successively; in addition, a blank group was set up with 10 C57BL/6J mice of 6-week old received 16-week high-fat feeding and saline treatment. Animals were sacrificed at the termination of the experiment, their paraffin sections of aortic tissue were used to measure the size of plaque, expressions of cavolin-1 and SR-BI were detected by immunological histochemical method.
RESULTSAs compared with the blank group, levels of caveolin-1 and SR-BI were increased in Groups A and B (P<0.01); but the increase in Group A was more significant than that in Group B (P<0.05). The plaque/aorta area ratio decreased significantly in Groups A and B, but showed insignificant difference between the two groups.
CONCLUSIONHXF could obviously increase the expressions of RCT associated genes, caveolin-1 and SR-BI, promote the RCT process, so as to reduce the formation of aorta atherosclerotic plaque in ApoE (-/-) mice.
