METHODS: Eighty-five hyperthyroid patients were randomly divided into two groups.The control group(40 cases) were treated with propylthiouracil,while the treatment group(45 cases) were treated with propylthiouracil and Zhibai Dihuang Pill;in the 12-week long treatment period,the heart rate,body weight,thyroid free FT_3、FT_4 and TSH and the serum level of FAA,resistin,adiponectin,leptin of patients in both groups were measured. RESULTS: After treatment,the heart rate,the serum of FT_3,FT_4 decreased and the body weight,TSH increased in both groups(P0.05).(CONCLUSION): Zhibai Dihuang Pill can improve the abnormal metabolism of sugar and fat in patients with hyperthyroidism by its actions on the serum level of FFA,resistin,adiponectin,leptin.

Objective To evaluate the preventative effects of rehabilitation training(RT)on deep venous thrombosis(DVT)after arthroplasty.Methods Fifty-six patients with articulatio coxae or knee arthroplasty were randomly divided into a control group and an experiment group(E group).RT,including active movement of the foot and ankle,isometric contraction of the quadriceps fexoris and deep breathing training,was administered to the E group after arthroplasty.Negative cheirapsis was applied in the control group.Peak and average blood flow velocities (PABFVs)in the femoral vein,as well as DVT,were detected and measured using color ultrasound Doppler imaging before and 7 d after arthroplasty.Results PABFVs in the E group were higher than those in the control group (P

ObjectiveTo investigate the long term effect of different antihypertensive agents on renal hemodynamics with ultrasound Doppler.Methods52 essential hypertensive patients were divided into three groups according to the antihypertensive agent they took: angiotensin-converting-enzyme inhibitor (ACEI), calcium channel blocker (CCB) and β-adrenoceptor blocker (βB). The blood pressures of right upper arms were measured with mercury column blood pressure gauge using Korotkoff method. Renal hemodynamics were examined with ultrasound Doppler before and after treatment with agents. ResultsSystolic blood pressure (SBP) and diastolic blood pressure (DBP) of all patients were decreased significantly. An significant correlation was found between the deceases of blood pressure and the betterment of renal homodynamic parameters in ACEI and CCB groups, but not in βB group. ConclusionTo a degree, the betterment of renal hemodynamics is correlation with the reduction of systemic blood pressure and mechanism of action of antihypertensive agents.

Objective To investigate the effect of professional attitude of nursing students with different educational backgrounds on the clinical ability. Methods 172 nursing students practiced in our hospital from July, 2006 to May, 2008 were given a self-designed questionnaire and invited to answer the questions in the form. Then, an analysis was conducted based on the surveyed results. Results For the total score of professional attitude and the total score of clinical ability of nursing students with different educational levels, the scores were (75.04±13.11) and (160.46±17.97) in the nursing undergraduates, (79.26±13.12) and (154.11±20.93) in the college nursing students, as well as (83.28±13.12) and (147.76±23.89) in the nursing students from senior high school, respectively. There was a correlation between the attitude and the total score (P<0.01 or P<0.05). Conclusions Professional attitude is highly correlated with clinical ability. A significant difference exists between students with baccalaureate degree, associate degree and technique degree. Occupational education such as students' ideological education, professional ethics and humanities education, should be enhanced in the higher education institutions by the education managers. In turn, the enhancement of the clinical ability may stabilize the professional attitude.

ObjectiveTo investigate the role of reducing the door-to-needle time for patients with acute ischemic stroke based on the quality improvement program of PDCA cycle.MethodsConsecutive patients with acute ischemic stroke admitted to hospital were registered prospectively from January 1, 2016 to September 30, 2016.Questionnaires and time tracking method were used to investigate the door-to-needle (DNT) and its influencing factors.PDCA cycle method was used to improve the stroke channel workflow and the changing trend of DNT was analyzed.ResultsA total of 71 patients with acute ischemic stroke were enrolled.After 3 PDCA cycles, DNT (median, interquartile range) from 100.0 min (65.5-127.0 min) reduced to58.0 min (45.5-80.0 min) (Z=11.689, P<0.001), the proportion of the patients with DNT ≤60 min increased from 19.05% to 60.00% (χ2=7.893, P=0.019).Conclusions The quality improvement program of PDCA cycle may effectively reduce the time of DNT in patients with acute ischemic stroke.

Objective To evaluate the effect of CYP3A5 genetic polymorphisms on tacrolimus (Tac) concentration/dosing and other clinical outcomes in a pilot cohort of 113 Chinese HTx recipients.Methods Association between CYP3A5 genetic variants and blood dose-adjusted trough concentrations (C0/D) of Tac at 1st month at the beginning of the immunosuppressive therapy was evaluated in cohorts of 113 patients,then at 1st,3rd,6th,and 12th months after transplantation in 41 patients who received Tac-based immunosuppressive therapy and never changed within one year after transplantation,respectively.In addition,we also evaluated the association between CYP3A5 genetic variants and other clinical outcomes,such as the classifications of endomyocardial biopsy and longterm prognosis.Results The CYP3A5 wild homozygote (* 1/* 1),mutant homozygote (* 3/* 3),and mutant heterozygote (* 1/* 3) occurred in 5,34 and 74 recipients respectively.The gene mutation rate of CYP3A5 in this cohort of Chinese HTx recipients was 80.5 ％ and the homozygous proportion was 65.5％.Compared with CYP3A5 expressors (* 1/* 1 or * 1/* 3),CYP3A5 nonexpressors (* 3/* 3) had a higher Tac C0/D at 1st month (47.34 ± 11.40 vs.116.11 ± 42.40 vs.293.70 ± 171.20,P =0.000),as well as other studied time points (3rd month:98.32 ± 39.43 vs.292.07 ± 141.08,P=0.003;6th month:90.00 ± 21.31 vs.341.68 ± 165.02,P =0.002;and 12th month:96.02 ± 29.33 vs.339.23 ± 162.30,P =0.018);and might have a lower classification of endomyocardial biopsy at 1st month (1.43 ± 0.73 vs.1.50 ± 0.58,P =0.867),3rd month (1.55 ±1.00 vs.2.00 ± 1.73,P =0.512),and 6th month (1.36 ± 0.84 vs.2.33 ± 1.53,P =0.132);as well as a higher mortality due to acute organ rejection (10％ vs.0,P =0.244) and all-cause mortality (20％ vs.9.7％,P =0.580).Conclusion In Chinese HTx recipients,the frequency of this * 3 allele is lower than that has been reported in the white population.The determinations of CYP3A5 genetypes in heart transplant recipients are helpful to guide the individualized Tac regimens.

ObjectiveTo study the effect of exercise training on β-amyloid polypeptide (Aβ) and β-secretase(BACE) in the hippocampus of the rats with vascular dementia (VD).Methods 30 Sprague-Dawley (SD) rats were carried out to an exercise group (n =10 ),a model group (n =10 ),and a sham-operation group ( n =10 ).VD rat models were made by the ligation of bilateral common carotid arteries.Morris water maze test were carried out 4 weeks after the operation to assess the ability in learning and memory of the rats and Aβ and β-secretase (BACE)expression was detected in the hippocampus of the rats using immunohistochemical techniques.ResultsIn the Morris water maze test,the model group showed reduction in the learning and memorizing ability,with obvious longer escape latencies ( ( 101.34 ± 19.67 ) s,(95.42 ± 23.89 ) s,( 89.39 ± 22.67 ) s,( 90.12 ± 19.77 ) s,respective-ly) than that of sham-operation group ( ( 62.13 ± 11.38 ) s,( 24.84 ± 13.69 ) s,( 16.98 ± 12.51 )s,( 11.41 ± 8.93 ) s,correspond-dingly) (P ＜ 0.05 ),and the exercise group was improved in the learning and memorizing ability ( corresponding to ( 80.15 ± 21.56 ) s,( 51.24 ± 20.91 ) s,( 43.78 ± 22.36) s,( 45.67 ± 20.87 ) s ),compared with the model group(P＜0.05).The grey values of Aβ in the hippocampus of the rats for the exercise group was ( 130.12 ± 19.01 ),( 116.77 ± 23.67 ) for the model group and ( 148.44 ± 17.67 ) for the sham-operation group(P＜ 0.05).The grey values of BACE in the hippocampus of the ratsfor the exercise group were( 131.21± 25.25 ),( 120.53± 10.21 ) for the model group(P＜ 0.05 ) and ( 162.38 ± 28.11 ) for the sham-operation group (P ＜ 0.05).ConclusionExercise training can lower the expression of BACE and Aβ in the hippocampus of rats with VD,therefore improving the learning and memory ability of rats with VD.

Objective To investigate the effect of herpes simplex virus thymidine kinase/ganciclovir (HSV-TK/GGV)system driven by human alpha fetoprotein(AFP)enhancer on hepatocellular carcinoma(HCC)cells in vitro and in vivo.Methods HCC-specific eukarotypic expression vector carrying suicide gene driven by AFP enhancer(pAFP-cDNA3.1-TK)was constructed.The plasmid was trasfected to AFP-positive HepG2 cells and AFP-negative SMMC7721 cells by liposomes.Protein and mRNA expressions of TK were detected by RT-PCR or Western blot.The survival rates of HCC cells were detected by methyl thiazolyl tetrazolium assay.The effects of GGV on the in vitro proliferation,survival and apoptosis of HCC cells were observed,and the inhibitive effect of GGV on the survival of HCC cells in vivo was also detected.All data were analyzed by using the t test.Results The pAFP-cDNA3.1-TK was successfully constructed and transfected to the HCC cells.The protein and mRNA expressions of TK were detected in AFP-positive HepG2 cells.GGV dose-and time-dependently inhibited the growth and induced the apoptosis of HepG2 cells in vitro,but it had no effect on SMMC7721 cells.No protein or mRNA expression of TK was detected in the SMMC7721 cells.There was a significant difference on the inhibitory effects of GGV on HepG2 cells and SMMC7721 cells(t =2.58,2.73,3.12,P ＜0.05).GGV specifically inhibited the growth of AFP-positive HepG2 cells,and the inhibition rate was 46%;the growth of AFP-negative SMMC7721 cells was not influenced by GGV.There was a significant difference in the inhibitive effect of GGV on the growth of HepG2 cells and SMMC7721 cells(t = 3.36,P ＜ 0.05).Conclusion HSV-TK/GGV systemdriven by human APF enhancer kills APF-positive HCC cells and inhibits the growth of HCC cells.
