ObJective To observe the efficay and adverse reactions of olmesartan combined with hydrochlorothiazide on patients with primary moderate hypertension,compared with the therapy of benazapril associated with amlodipine.Methods 116 primary moderate hypertension patients were randomly divided into the treatment group and control group.Patients in treatment group were treated with olmesartan combined with hydrochlorothiazide oral administration,and control group were given benazapril combined with amlodipine oral administration,which lasted for 3 weeks.Every subject was measured blood pressure before and after the drug administration and observed adverse reaction.Cardiac hypertrophy was detected by UCG.A comparison was made in effectiveness of the drug and cardiac hypertrophy between two groups.Results There was significant difference in effectiveness of two anti-hypertension therapies,and cardiac hypertrophy in the treatment group was lighter than that in control group.Conclusion The therapy of olmesartan combined with hydrochlorothiazide was more effective than that of benazapril combined with amlodipine,also more depressed cardiac hypertrophy.

The clinical prescriptions of hemoptysis that built by Menghe physician Ma Peizhi were collected, and were analyzed by the method of unsupervised data mining, such as association rules and clustering algorithm. From the prescriptions, we got the frequency of drugs, the association rules among drugs, 10 core drug combinations and 5 new prescriptions. Accordingly, after the analysis, Menghe physician Ma Peizhi had rich experience in the treatment of hemoptysis. His therapy for hemoptysis was clearing heat and moistening lung, dispel heat from blood to stop bleeding, and enriching yin and blood. And we can also make a conclusion that the TCM inheritance support system is of great practical value for minning the old doctors' clinical experiences.

OBJECTIVETo explore the effects of Wenyang Huazhuo Tongluo Recipe (WYHZTLR) containing serum on transforming growth factor β1 (TGF-β1)/Smad signaling pathway of skin fibroblasts in systemic sclerosis (SSc).

METHODSTotally 36 SSc patients were randomly assigned to Chinese medicine (CM) group, Western medicine (WM) group, and integrative medicine (IM) group according to random digit table, 12 in each group. Patients in the CM group took WYHZTLR decoction (one dose per day). Patients in the WM group took penicillamine tablet (0. 125 g each time, bid) and Prednisone Acetate Tablet (PAT 20 mg, qd). Patients in the IM group took penicillamine, PAT, and WYHZTLR decoction (in the same dosage of corresponding drugs as aforesaid). All patients were treated for one month to get drug containing serum. Besides, 10 untreated SSc patients' serum was taken as the control group. Healthy subjects' skin fibroblasts were originated from healthy skin tissue of the upper arms of 2 female patients undergoing plastic surgery. Corresponding serum of each group was added in the culture system of SSc patients' and healthy subjects' dermal fibroblasts respectively. Expression levels of TGF-β1 receptor type I (TGF-β1 RI), TGF-β1 receptor II (TGF-β1 RII), p-Smad2/3 and Smad7 protein were examined by Western blot. Expression levels of collagen type I and collagen type III (Col-I, Col-III) mRNA were examined by reverse transcription PCR. Contents of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinases-1 (TIMP-1) in the supernatant of SSc, skin fibroblasts were examined by ELISA.

RESULTSCompared with the control group, expression levels of TGF-β1 R I and p-Smad2/3 protein significantly decreased, but expression levels of Smad7 protein significantly increased in skin fibroblasts of SSc patients and healthy subjects of WM, CM, and IM groups (P <0.05, P <0. 01). Meanwhile, the expression level of TGF-β1 RII decreased in the IM group (P <0. 05, P <0. 01). Compared with the WM group, expression levels of TGF-β1 RI and p-Smad2/ 3 protein significantly decreased, but that of Srnad7 protein significantly increased in IM groups (P <0. 01). mRNA expression levels of Col-I and Col-II in SSc skin fibroblasts significantly decreased more in WM, CM, and IM groups than in the control group (P <0. 05, P <0. 01). Besides, the expression level of Col-III mRNA was significantly lower in the IM group than in the WM group (P <0.01). Compared with the control group, serum levels of MMP-9 and MMP-9/TIMP-1 ratios increased more obviously in WM, CM, and IM groups (P <0.05, P <0.01). But expression levels of TIMP-1 decreased significantly in CM and IM groups (P <0.01). Expression levels of MMP-9 and MMP-9/TIMP-1 ratios increased more in the IM group than in the WM group (P <0. 01). Expression levels of TIMP-1 decreased more in CM and IM groups than in the WM group (P <0.01).

CONCLUSIONWYHZTLR containing serum could reduce expression levels of Col-I and Col-III possibly through regulating key signal molecules, such as TGF-β1 RI, p-Smad2/3, and Smad7 in TGF-β1/Smad signaling pathway of SSc skin fibroblasts, and inhibiting transduction of TGF-β1/Smad signaling pathway.

To improve ethanol production in Saccharomyces cerevisiae,an integration plasmid pUPGKAT with PGK promoter(phosphoglycerate kinase promoter),adh1 gene(the coding sequences of alcohol dehydrogenaseⅠ) and CYC1 terminator(Cytochrome c transcription terminator) was constructed.Firstly,a fusion fragment composed of PGK promoter and adh1 gene was generated by over lap extension PCR and ligated into pUG6 resulting in plasmid pUPGKA.Subsequently,CYC1 termi nator was amplified from pSH65 by PCR and ligated to the SpeⅠand SacⅡrestriction site of pUPGKA.To integrate PGK-adh1-CYC1 into S.cerevisiae genome,pUPGKAT was digested by TthⅢⅠand the lin-earized plasmid was used to transform S.cerevisiae YS2-△adh2(adh2 disrupted strain) by lithium acetate method.The yeast mutant YS2-△adh2-adh1 which had the adh1 gene placed under the PGK promoter and harbored the adh2 deletion was constructed.Anaerobic fermentation showed overexpression of adh1 by PGK promoter resulted in a 8.84% higher ethanol production compared to YS2-△adh2.

Analyzed the prescriptions for phlegm retention syndrome that built by Ma Peizhi by the association rules and clustering algorithm, the frequency of drug usage and the relationship between drugs could be get. And from that we could conclude the experiences for phlegm retention syndrome of Ma Peizhi of menghe medical genre. The results of the analysis were that 18 core combinations were dig out, such as Citri Exocarpium Rubrum-Eriobotryae Folium-Citri Reticulatae Pericarpium. And there were 9 new prescriptions were found out such as Aurantii Fructus-Citri Exocarpium Rubium-Eriobotryae Folium-Citri Reticulatae Pericarpium. The results of the analysis were proved that Ma Peizhi of Menghe Medical Genre was good at curing phlegm retention syndrome by using the traditional Chinese medicine of mild and light, such as the medicines of mild tonification, and clearing damp and promoting diuresis.

Objective To investigate protein expression of telomerase reverse transcriptase(TERT),telomerase-associated protein 1(TP1) and telomeric repeat binding factor 2(TRF2) in human fetal cadiacmyocytes.Methods Using immunohistochemical method,sections of human fetal hearts were stained with antibodies against TERT,TP1 and TRF2.Results Expression of TERT was gradually decreased with development in human fetal cadiacmyocytes nuclear.Expression of TP1 and TRF2 was gradually increased with development in human fetal cadiacmyocytes cytoplasm.Conclusion Down-regulation of TERT and up-regulation of TP1 and TRF2 may promote the permanent withdrawal of cardiomyocytes from the cell cycle and enter terminal differentiation and myocardium hypertrophy.
