Conclusion The assumable reasons for the dominance of heterozygous ADH2 genotype were a relatively small size of samples or gene mutation etc,which needed further researches to be confirmed.The proportion of individuals carrying about "susceptible genotypes of alcohol_related diseases"in female child_bearing ages was more than one half (0.617),which called on the reinforce of the surveillance on and prevention of alcohol_related birth (ARBD).

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 efficacy and safety of AlumaTM functional aspiration controlled electrothermal stimulation (FACES) radiofrequency in the treatment of skin wrinkles and laxity on the face and neck. Methods A total of 30 volunteers with aging skin were recruited in the study. All volunteers were treated with AlumaTM FACES radiofrequency for 6 times at 2-week interval. Photographs were taken for volunteers before every treatment and 1 month after the last treatment. Improvement in lesions was objectively assessed by two separate physicians based on the photographs of volunteers taken before the first,fourth and sixth treatment, and 1 month after the last treatment. Patient satisfaction was measured by ques-tionnaire. Adverse effects were recorded. Results Totally, 24 volunteers completed the treatment. Improve-ment of lesions was achieved in 66.7% of the volunteers after 3 treatments, 90.5% after 5 treatments, and 94.4% one month after the last treatment. About 50% of the volunteers were satisfied with the effect after 3 treatments, 90.5% after 5 treatments, and 100% one month after the last treatment. Slight purpura was the most common side effect. Conehusion Radiofrequency therapy is effective for skin wrinkles and laxity on the face and neck, without obvious side effect.

Objective To investigate the effect of penehyclidine hydrochloride ( PHC) pretreat?ment on nuclear factor erythroid 2?related factor 2∕heme oxygenase?1 ( Nrf2∕HO?1) signaling pathway in re?nal tissues of rats with rhabdomyolysis?induced acute kidney injury ( AKI) . Methods Thirty?six pathogen?free male Sprague?Dawley rats, weighing 200-220 g, were assigned into 3 groups ( n=12 each) using a random number table: control group (group C), group AKI and PHC pretreatment group (group PHC). Rhabdomyolysis was induced by intramuscular injection of 50% glycerol 10 ml∕kg in bilateral hindlimbs. PHC 0?2 mg∕kg was injected intraperitoneally at 30 min before glycerol was injected intramuscularly in group PHC. At 1 and 6 h after glycerol injection, serum was collected for determination of blood urea nitro?gen ( BUN) and creatinine ( Cr) concentrations, and bilateral kidneys were harvested for pathological ex?amination and for determination of HO?1 activity and expression of Nrf2 mRNA and HO?1 mRNA ( by quan?titative real?time polymerase chain reaction) , Nrf2 in nucleoprotein and total protein and HO?1 in total pro?tein in renal tissues ( by Western blot) . The damage to the renal tubules was scored. Results Compared with group C, the BUN and Cr concentrations in serum and renal tubular damage scores were significantly increased, the expression of Nrf2 in nucleoprotein and total protein and HO?1 in total protein was signifi?cantly up?regulated, and HO?1 activity was significantly increased in AKI and PHC groups, the expression of HO?1 mRNA was significantly up?regulated in group AKI, and the expression of Nrf2 mRNA and HO?1 mRNA was significantly up?regulated in group PHC (P<0?01 or 0?05). Compared with group AKI, the BUN and Cr concentrations in serum and renal tubular damage scores were significantly decreased, the ex?pression of Nrf2 in nucleoprotein and total protein and HO?1 in total protein was significantly up?regulated, and HO?1 activity was significantly increased in group PHC ( P<0?01 or 0?05) . Conclusion The mecha?nism by which PHC pretreatment attenuates rhabdomyolysis?induced AKI may be related to activation of Nrf2∕HO?1 signaling pathway in renal tissues of rats.

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).

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 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.
