Objective To provide evidence for the pharmacological action of blood-activating and blood-stasis-dissipating medicines by studying the influence of Zhenxintong Oral Liquid (ZOL) on thrombus-associated marker levels in coronary heart disease with blood-stasis syndrome. Methods Forty male Wistar rats were randomly allocated to 5 groups: normal group,model group,large-dose ZOL group,small-dose ZOL group and Compound Danshen Drip Pill(CDDP) control group. Blood-stasis models were established by peritoneal injection of dexamethasone (0.25mg?kg-1?d-1). After 8 days of treatment,levels of activated partial thromboplastin time (APTT),antithrombin -Ⅲ(AT-Ⅲ),tissue-type plasminogen activator (t-PA) and tissue-type plasminogen activator inhibitor (PAI) in blood from abdominal aorta were determined. Results AT-Ⅲlevel in the two ZOL groups and in CDDP control group was significantly higher than that in model group(P 0.05). t-PA level was higher and PAI level was lower in large-dose ZOL group than that in CDDP control group (P

OBJECTIVE:To compare the difference of the information about smoking affecting pharmacodynamics and pharma-cokinetics in prescription drug instructions between US and China. METHODS:The US and Chinese guidance for drug R&D and drug instructions editing,prescription drug instructions were collected;the information about smoking affecting pharmacodynamics and pharmacokinetics were retrieved from FDA drug instruction official website DailyMed and Yaozhi Network in China up to Jun. 19th,2014. The difference in related regulations and drug instruction were compared between US and China. RESULTS & CON-CLUSIONS:The guidance issued by US and China require that great importance should be attached to the effects of smoking on pharmacodynamics and pharmacokinetics,and it must be noted in drug instructions. Of 62 857 drugs recorded,smoking affected pharmacodynamics and pharmcokinetics of 34 drugs in US drug instructions,among which 9 drugs needed dose modifications;for above drugs,Chinese drug instructions pointed out great importance should be attached to the effect of smoking on pharmacodynam-ics and pharmacokinetics of 6 drugs,and only one drug(erlotinid hydrochloride)needed to be modified. The label rate of smoking affecting pharmacodynamics and pharmacokinetics was relatively low in Chinese drug instructions compared to US. It is suggested that the regulatory agent should standardize and improve related description in drug instruction,correct unsuitable content,revise the items which may result in severe consequence,and set up official website which can provide all drug instructions as soon as possible. Drug manufacturers should standardize clinical study of drugs before marketing,focus on the scientificity,completeness and normalization of drug instructions.

Objective To compare the hypnotic effect of propofol administered by target-controlled infusion (TCI) during day-time and night-time,in order to explore the effect of circadian rhythms on the sedative effect of propofol.Methods Sixty-five male ASA Ⅰ or Ⅱ patients aged 18-55 yr undergoing emergency minor hand surgery were divided into 2 gorups according to the time of the day when they received propofol TCI:day-time group (from 7:01 to 19:00) and night-time group (from 19:01 to 7:00).The pharmacokinetic parameters proposed by Schnider which predict effect-site concentration (Ce) were used.Four effect-site concentrations of propofol were set:0.8,1.2,2.0 and 4.0 μg/ml.Ce was increased step by step and each Ce was maintained for 5 min.The level of sedation at each Ce was assessed by BIS and OAA/S scores.BIS value and Ce of propofol were recorded and compared between the 2 groups when the patients lost consciousness (OAA/S score =2).Results There was 28 and 30 patients in day-time and nighet-time groups respectively.When Ce =1.2 and 2.0 μg/ml,the BIS values were significantly lower in night-time group than in day-time group.There was no significant difference in BIS value between the 2 groups when Ce =0.8 and 4.0 μg/ml.When the patients lost consciousness (OAA/S =2),the BIS value was comparable between the 2 groups,but Ce was significantly lower in night-time group than that in daytime group.Conclusion The hypnotic effect of propofol is greater during night-time than during day-time.

Objective To discuss the treatment method and prognosis of posterior hip dislocation combined with femoral fractures. Methods Twenty nine patients who had been diagnosed as cases of posterior hip dislocation combined with femoral head fracture were reviewed, with their type of fracture, timing of treatment and method of treatment analyzed. Twenty seven (93.1%) of the 29 cases were followed up from 1987 to 2002 for an average period of seven years. Their prognosis was evaluated according to the x ray radiography and the function of hip joints. Results According to Pipkin IV classification, 13 cases were Pipkin Ⅰ(44.8%), 9 cases Pipkin Ⅱ(31%), 3 cases Pipkin Ⅲ(10%), and 4 cases Pipkin Ⅳ(14.2%). In type I, 9 cases were rated as excellent (33.3%), 2 good (7.4%), 1 fair (3.7%) and 0 poor (0%) by Harris hip score. In typeⅡ, 0 case was rated as excellent (0%), 2 cases good (7.4%), 4 fair (14.9%) and 2 poor (7.4%). In type Ⅲ, 1 case was rated as excellent, 0 good (0%), 1 fair (3.7%) and 1 poor (3.7%). In type Ⅳ, 0 case was rated as excellent (0%), 2 good (7.4%), 1 fair (3.7%) and 1 poor (3.7%). In all the 29 cases, those which needed total hip arthroplasty (THA) were four (13.7%). Conclusions The choice of treatment method should be determined by the mechanism of injury and the type of fracture. The factors ensuring a satisfactory prognosis are: (1) The age of the patients should be younger than 40 years. (2) Since a timely reduction can prevent the onset of avascular necrosis of femoral head, it should be finished within 12 hours after the injury, and the fixation should be done within 10 days. (3) In all types, early reduction of hip dislocation, early stabilization, anatomic reduction of the fracture should be achieved. (4) The prevention of possible complications should be taken into serious consideration.

Objective To compare the hypnotic effects of propofol administered by target-controlled infusion (TCI in daytime and nighttime,in order to explore the effect of circadian rhythm on the sedative effect of propofol.Methods Sixty-five male ASA Ⅰ or Ⅱ patients,aged 18-55 years,with the body mass index (BMI) of 18.5-24.9 kg/m2,undergoing emergency minor hand surgery were divided into two groups according to the time of the day when they received TCI of propofol:daytime group (from 07:01 to 19:00) and nighttime group (from 19:01 to 07:00).The pharmacokinetic parameters proposed by Schnider et al.which suggested the effect-site concentration (Ce) was used.Four Ces of propofol were set at 0.8,1.2,2.0 and 4.0 μg/ml,respectively.Ce was increased step by step and each Ce was maintained for 5 minutes.The level of sedation at each Ce was assessed by bispectral index (BIS) and observer's assessment of alertness/sedation (OAA/S) scores.BIS values and Ces of propofol were recorded and compared between the two groups when the patients lost consciousness (OAA/S score =2).Results There were 28 and 30 patients in daytime and nighttime groups,respectively.When Ces were 1.2 and 2.0 μg/ml,the BIS values were significantly lower in the nighttime group than in the daytime group.There was no significant difference in BIS values between the two groups when Ces were 0.8 and 4.0 μg/ml.When the patients lost consciousness (OAA/S =2),the BIS value was comparable between the two groups,but Ce was significantly lower in the nighttime group than in the daytime group.Conclusion The hypnotic effect of propofol is greater during night time than during day time.

Objective To investigate the relation of serum leptin level in senile depressive patients with type 2 diabetes and polymorphisms of leptin receptor gene 3057 G/A.Methods 10 senile depressive patients with type 2 diabetes and 47 senile depressive patients without type 2 diabetes were selected for the study.Leptin levels were determined by radioimmunoassay.Genomitic DNA were obtained by phenol/chloroform method.Leptin receptor gene 3057 G/A polymorphisms and allele frequencies were determined with the polymerase chain reaction and restricted fragment length polymorphism assay.Results (1) The differences of leptin receptor genotypes and allele distribution in the 3 groups were not found (all P ＞ 0.05).(2) Serum leptin level in senile depressive patients with type 2 diabetes and without type 2 diabetic patients ((41.65 ± 28.19) ng/ml,(25.56 ± 21.04) ng/ml) were significantly higher than the normal people ((10.84 ± 9.16) ng/ml) (all P ＜ 0.05).Serum leptin level in senile depressive patients with type 2 diabetes were significantly higher than without type 2 diabetic patients(P＜ 0.05).(3) The serum leptin level in genotype AA senile depressive patients with type 2 diabetes were significantly higher than genotype AA patients without type 2 diabetes.The differences of the serum leptin levels in genotype AA senile depressive patients without type 2 diabetes and genotype AG/GG patients without type 2 diabetes were not found(P ＞ 0.05).The differences of the serum leptin level in genotype AA and genotype AG/GG in normal groups were not found (P＞ 0.05).Conclusion Senile depressive patients have higher serum leptin level.The serum leptin level is higher,especially with type 2 diabetes.Serum leptin level is related to type 2 diabetes.Serum leptin level is not related to the polymorphisms of leptin receptor gene 3057 G/A.Type 2 diabetes are not related to polymorphisms of leptin receptor gene 3057 G/A.

Objective To observe the effects of recruitment maneuver (RM) and tidal volume with different amount of gas after RM ventilation on lung diastole function in rats with acute lung injury (ALI). Method ALI rat models were induced by intravenous infusion of lipopolysaccharide (LPS) in dose of 6 mg/kg. Twenty-five rats were randomly(random number) divided into control group ( n = 5), ALI group ( n = 5), low tidal volume group (LV group,VT= 6 mL/kg, n = 5), sustained inflation (SI) with low tidal volume (SI+ LV group, VT=6 mL/kg, n = 5), and SI with moderate tidal volume group (SI+ MV group, VT= 12 mL/kg, n = 5). The RM carried out by using SI with airway pressure 30 cmH-2O for 30 seconds, and the positive end-expiratory pressure (PEEP)was set at 5 cmH2O. Lung tissue was taken after mechanical ventilation for 5 hours. The mean arterial pressure (MAP) was monitored throughout the entire course of experiment. Endothelin-1 ( ET-1 ), endothelial nitricoxide synthase (eNOS), and acetylcholine-(Ach-) induced endothelium-dependent relaxation response of isolated pulmonary artery rings were investigated after mechanical ventilation for 5 hours. Results The LPS increased the ET-1 level in lung tissue, decreased the level of eNOS in lung tissue, and impaired the Ach-induced endothelium-dependent relaxation response in pulmonary vassals, without obvious influence on systemic hemodynamics. SI + LV significantly reduced LPS-induced elevation of ET-1 level, and increased the level of eNOS, and significantly lessened endothelial dysfunction and ameliorated dysfunction od endothelium-dependent relaxation in pulmonary vas sals. Conclusions RM with high tidal volume or lowtidal volume ventilation could improve the lung vascular endothelial function of rats with acute lung injury, and RM with low tidal volume ventilation could lessen more the injury of lung vascular endothelial diastole function in rats with acute lung injury.

Objective: To assess the trend of statin application for in-hospital acute myocardial infarction (AMI) patients with its impact factors in eastern urban China from 2001 to 2011. Methods: A 2-stage random sampling design was performed to extract representative AMI sample patients. In the ifrst stage, a simple random-sampling was used to identify participating hospitals. In the second stage, a systematic sampling was conducted in 2001, 2006 and 2011 to select the cases from participating hospitals, to take medical records and clinical information for calculating the in-hospital statin application rate. The impact factors for statin application was assessed by multi Logistic regression model with generalized estimating equations. Results: A total of 5940 AMI records from 32 hospitals were enrolled. From 2001 to 2011, the in-hospital statin use rate increased from 46.0% in 2001 to 82.2% in 2006 and to 93.7% in 2011,P<0.001 for trend. Multi Logistic regression analysis indicated that the patients with LDL-C>3.37 mmol/L were more likely to receive statin therapy than those with LDL-C<1.81 mmol/L (OR=1.59, 95% CI 1.10-2.30,P=0.013); the patients with chest pain at admission (OR=1.82, 95% CI 1.14-2.91, P=0.012), combining hypertension (OR=1.44, 95% CI 1.02-2.03,P=0.038), with in-hospital PCI (OR=2.99, 95% CI 1.71-5.23, P<0.001) were also more likely to receive statin therapy. The application rate of statin was reduced by reduced LDL-C level accordingly and the patients without LDL-C examination, accounting for 21.3%, had the lowest statin application rate. Conclusion: Statin therapy for in-hospital AMI patients was dramatically increased from 2001 to 2011 in eastern urban China and the guideline was rapidly popularized in clinical practice. However, the improvement has been needed especially in patients without LDL-C examination or with low LDL-C levels; we emphasize that AMI patients should receive statin therapy regardless their LDL-C levels.

Objective To identify the effective results of ultrasound in degradation of polymeric nanoparticles released DNA .Polymeric nanoparticles was made by dehydration of polyacetylglutamicacid (PLGA, polylactic-co-glycolic acid)solution. Method Green Fluorescent Protein (GFP) was enclosed by PLGA. Different kinds of ultrasound mode and different duct cycle and power ones were used to radiate PLGA solution for 90 s, 9 min, 20 min separately after the solution prepared for 2 hrs,then putted the solution on centrifugal machine at 13000 r/m. Using Choloroform to get rid of fat-soluble impurity,then applied nanodrop to survey the releasing rate of DNA. Finally the effect of cell expression were observed by fluorescent microscope. Results The amount of DNA released from PLGA in groups which were exposed to ultrasound were significantly different from the groups which were not exposed to ultrosound. The releasing amount of former groups had upper limitation. The releasing rate was increased with the increment of the irradiation time,frequency of ultrasound;The effect of the DNA releasing and PLGA degradation by continuous-wave irradiation was stronger than pulsed-wave ultrasound. Conclusion Ultrasound can promote the degradation of PLGA, and do help in DNA releasing and expression in vitro.
