Objective To determine the role of fosinopril and valsartan intervention in Klotho, matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1) and plasminogen activator inhibitor (PAI-1) gene expression in hypertensive renal interstitial fibrosis (RIF) in the kidney tissue of spontaneously hypertensive rats (SHR). MethodsWe randomly divided 20 male 22-week-old SHR into 4 groups (5 in each group):a hypertension group (SHR group), a fosinopril group ［Fos group, 10 mg/( kg·d) gavage］, a valsartan group ［Val group, 10 mg/( kg·d) gavage］， and a fosinopril plus valsartan group ［Fos + Val group, fosinopril 10 mg/( kg·d) + valsartan 50 mg/( kg·d) gavage］. Another five 22-week-old male Wistar Kyoto rats (WKY) were used as controls. Through monitoring the weight of the rats, tail artery pressure, 24-hour urine protein by fosinopril and/or valsartan intervention after the 8-week trial. RT-PCR and Western blot were used to detect the mRNA and protein expression of Klotho, MMP-9, TIMP-1, and PAI-1 in the kidneys.Results RT-PCR showed that in the SHR group, Klotho mRNA and protein expression were significantly decreased(P＜0.01), while mRNA and protein expression of MMP-9, TIMP-1, and PAI-1 were significantly higher compared with the WKY group(P＜0.01). With fosinopril and / or valsartan intervention, Klotho mRNA expression in the Fos group (P＜0.01), Fos + Val group (P＜0.01), Val group (P＜0.05), Klotho protein expression in the Fos group(P＜0.05), Fos + Val group (P＜0.05), Val group (P＜0.01), were significantly increased compared with those in the SHR group. The mRNA and protein expression of MMP-9, TIMP-1, and PAI-1 in the Fos group, Val group, and Fos + Val group were significantly lower than those in the SHR group (P＜0.01). The expression of Klotho mRNA had negative correlation with the expression of MMP-9 mRNA (r= -0.864, P<0.01), TIMP-1 mRNA (r=-0.725, P<0.01) and PAI-1 mRNA (r=-0.785, P<0.01). The Klotho protein expression had negative correlation with the expression of MMP-9 protein (r=-0.614, P<0.05), TIMP-1 protein (r=-0.579, P<0.05), and PAI-1 protein (r=-0.552, P<0.05). Conclusion Anti-aging gene Klotho and the genes related with extracellular matrix degradation gene MMP-9, TIMP-1, PAI-1 are involved in hypertensive renal injury. The expression of Klotho and MMP-9, TIMP-1, and PAI-1 is closely correlated. Fosinopril and valsartan which increase the Klotho mRNA and protein expression can alter the expression of Klotho-MMPs/TIMPs, which may be the main mechanism to prevent interstitial fibrosis.

Objective To evaluate the ability of matrix-assisted laser desorption/ionization time-offlight mass spectrometry (MALDI-TOF MS) in identifying species of Acinetobacter calcoaceticus-Acinetobacter baumannii complex,and investigate the species distribution of Acinetobacter calcoaceticus-Acinetobacter baumannii complex isolated in our hospital.Methods A total of 502 nonduplicate clinical isolates of Acinetobacter calcoaceticus-Acinetobacter baumannii complex were retrospectively collected from the second affiliated hospital of Zhejiang University between January 2012 and July 2012.All strains were re-identified by MALDI-TOF MS and were also verified by sequence analysis of 16S-23S rRNA gene spacer region.Results Among all the 502 strains of Acinetobacter calcoaceticus-Acinetobacter baumannii complex,identificaion results provided by MALDI-TOF MS were A.baumannii (431,85.9％),A.pittii (68,13.5％),A.calcoaceticus (3,0.6％).Sequence analysis of 16S-23S rRNA gene spacer region was used to identify all the 502 strains:403 (80.3％) were identified as A.baumannii,68 (13.5％) as A.pittii,28 (5.6％) as A.nosocomialis and 3 (0.6％) as A.calcoaceticus.MALDI-TOF MS correctly identified all the strains but erroneously identified all 28 strains of A.nosocomialis as A.baumannii,compared with sequence analysis of 16S-23S rRNA gene spacer region.Conclusions MALDI-TOF MS can be used as a fast,simple,reliable and excellently reproducible method to identify members of Acinetobacter calcoaceticus-Acinetobacter baumannii complex at low costs.MALDI-TOF MS is expected to be an ideal technique for routine clinical microbiology testing in the future.

OBJECTIVE:To optimize the extraction technology of Compound qima capsules. METHODS:With the blood pres-sure lowering of rats as index,pharmacological efficacy test was used to screen the preparation technology(A was whole herb de-coction;B was Gastrodia elata fine powder mixed with other decocted medical materials). The extraction technology was opti-mized by single factor and orthogonal test using the contents of astragaloside and isoflavone grape glycosides and the quality of sol-id as indexes,with added water,decoction time,decoction times as factors;and the verification test was carried out. RESULTS:Pharmacological efficacy test showed that antihypertensive effect of sample by technology B was superior. The optimal extraction condition of other medical materials of technology B was as follows as 12-fold water per time,decocting for 1.5 h,for 3 times. In verification test,average extraction rates of astragaloside and isoflavone grape glycosides were 64.02% and 51.97%,and average value of the quality of solid was 5.69 g(RSD≤1.92%,n=3). CONCLUSIONS:The optimized extraction technology is stable and feasible.

Objective To compare the clinical efficacy and adverse effects of photodynamic therapy (PDT) versus pulsed dye laser(PDL)for the treatment of port wine stains(PWS). Methods Forty?five patients with PWS were enrolled in this study. The PWS lesions in each patient were randomly divided into PDT and PDL areas. Hematoporphyrin monomethyl ether of 5 mg/kg was injected intravenously into the PDT area protected from light, followed by 20?minute irradiation with a 532?nm, solid?state, continuous?wave laser(power density:80-100 mw/cm2;spot diameter: 7 cm)10 minutes later. The PDL area was treated with a single session of 595?nm pulsed dye laser radiation(spot diameter:7 mm;pulse width:10 ms;energy density:10-12 J/cm2). The interval between PDT and PDL treatment was no shorter than two months. Follow up visits were scheduled on day 4 and week 8 after each treatment. Adverse reactions were recorded, and photographs were taken before and 8 weeks after the treatment for evaluation of lesion regression. Results In the case of PDT area, 10 cases(22.22%)were nearly cured, 22(48.89%)achieved marked improvement, 9(20.00%)improvement, 4(8.89%)no improvement. As far as the PDL area is concerned, 6 cases(13.33%)were nearly cured, 16(35.56%)achieved marked improvement, 18(40.00%)improvement, and 5 (11.11%)no improvement. The response rate was significantly higher in the PDT area than in the PDL area(Z=2.48, P<0.05). Hyperpigmentation, which spontaneously subsided within 3 to 6 months, was the main adverse reaction. No significant difference was found in the incidence rate of adverse reactions between the PDL and PDT areas(24.44%vs. 15.56%, Z=1.26, P>0.05). Conclusion For the treatment of PWS, both PDT and PDL are effective and safe, and single?session PDT appears to be superior to single?session PDL.

Objective To retrospectively analyzed the current application of warfarin in hospitalized patients with non-valvular atrial fibrillationand ( NVAF), explore the key role of clinical pharmacists in warfarin medication. Methods A retrospective survey of anticoagulant therapy for 179 hospitalized patients with non-valvular atrial fibrillation in Renming Hospotal of Wuhan University from January to December 2013 was retrived,including the usage of warfarin for NVAF and new-onset atrial fibrillation,dosage,international normalized ratio(INR),hemorrhage event and so on.The simple factor like the age,complicated chronic diseases and previous cerebrovascular events on the use of warfarin was explored. Results The total response rate to anticoagulants was 85.6% for patients with high risk of stroke(27.3% with warfarin and 58.3% with antiplatelet therapy),who are recommended to use warfarin,patient were treated with anti-thrombotic therapy.The total of 19.1% of the patients with new-onset atrial fibrillation used warfarin as therapy.The whole monitoring rate of INR was 89.8%,and the good control rate was 11.9%. Univariate analysis showed that some high risk factors such as age and high blood pressure affected the usage of warfarin. Conclusion The anti-thrombotic therapy for NVAF patients in the hospital is good,but usage of warfarin for those with new-onset atrial fibrillation is low,which couldn't reach the INR standard. More attention should be taken by the clinic pharmacists in effective managing the use of anticoagulant to build a safe,economic and effective medication system for warfarin application.

Objective To observe the influence of Buyang Huanwu Decoction ( BYHWD) on the inhibition of rat myocardial H9C2 cell activity and SH2-containing tyrosine phosphatase-1 ( SHP-1) activity induced by trastuzumab, and to explore the possible regulatory mechanism after observing the intervention of BYHWD on rat myocardial H9C2 cell transfected with SHP-1 or SHPC/S-1 gene. Methods The eukaryotic expression vectors pcDNA3.1 (+)- SHP-1 and pcDNA3.1 (+) -SHPC/S–1 were constructed and then were transfected to rat myocardial H9C2 cells using the method of liposome transfection. The cells with positive clones were screened out with G418, and then were cultured with trastuzumab for maintaining growth. Using quantitative RT-PCR, we detected the expression of SHP-1 gene and SHPC/S - 1 gene in rat myocardial H9C2 cells. The phosphatase activity analysis was used for observing the regulatory effect of BYHWD on SHP-1 in myocardial cells. Furthermore, we observed the apoptosis of rat myocardial H9C2 cells by methyl thiazolyl tetrazolium (MTT) assay after treatment with BYHWD. Results Sequencing results indicated the successful construction of eukaryotic expression vectors, which had stable expression in myocardial H9C2 cells even under the intervention of trastuzumab. The results of phosphatase analysis showed that H9C2-SHP-1 had the highest activities of phosphatase, but the activities were decreased after the intervention with BYHWD ( P<0.05) . The results of MTT assay also showed the apoptotic rate of H9C2-SHP-1 cells was decreased after treatment with BYHWD ( P <0.05) . Conclusion BYHWD can promote the proliferation of myocardial H9C2 cells inhibited by trastuzumab, and can regulate the expression of SHP-1 in myocardial cells, which will supply reference to the further study of treatment of trastuzumab-induced cardiac toxicity.
