OBJECTIVE:To provide reference for prescriptions audit before payment in hospital pharmacy. METHODS:The management measures of prescriptions audit and intervention before payment in our hospital were introduced. 1 200 outpatient pre-scriptions within 1 year before and after management were subjected to a statistical analysis. The effects of prescriptions audit be-fore payment were evaluated through analyzing and comparing qualification rate of prescription and unqualified prescriptions. RE-SULTS:Our hospital adopted a series of measure to realize prescriptions audit and intervention before payment by clinical pharma-cists,such as using information audit system,formulating audit standard,educating pharmacists,establishing audit job system, prescriptions review and feedback system,setting up communication system,etc. Of the total audited 189 665 prescriptions, 14 581(7.69%)failed to audit and 606 prescriptions hadn’t been revised after 1 year management,with effective intervention rate of 95.84%. Compared with before management,the prescription qualification rate increased from 88.83% to 98.67% after manage-ment(P<0.01). The quantity of overdose,inconformity with medical insurance,overload and other conditions reduced to 0. CON-CLUSIONS:It is feasible for pharmacists to audit and intervent prescriptions before payment in hospital pharmacy to improve pre-scription qualification and promote rational drug use in the clinic.

Objective To observe the impact of the five-emotion restrictive therapy on coronary heart disease. Methods109 hospitalized patients with coronary heart disease were randomly divided into a experimental of 56 patients and a control group of 53 patients according to length of stay. The control group was treated with the conventional therapy; the experimental group was imposed five-emotion restrictive psychological intervention on the basis of conventional therapy. The investigation was done using self-rating anxiety scale(SAS) and self-rating depression scale(SDS) on 1 day after admission and ld before discharge respectively. SAS and SDS scores were surveyed. At the same time Holter monitoring and normal ECG test were compared. Results Compared with control group, the experimental group 1 d before discharge of the SAS and SDS scores were (41.9±7.4) and (38.6±8.4), and the difference was statistically significant (P＜0.01) . The total effective rate of Holter monitoring and normal ECG was 64.15％ and 92.85％ in the control and experimental group, and the difference was significant (P＜0.01) . ConclusionThe pathological seven emotions have a certain affection on the incidence of coronary heart disease, treatment and prognosis of the course. Five-emotion restrictive psychological intervention can adjust timely psychological state of patients, eliminate negative emotions, and significantly help the incidence, treatment and prognosis of the disease.

ObjectiveTo investigate whether subjects with major depression display attention deficits.Methods35 antidepressant-free,non-elderly patients with unipolar depression diagnosis according to ICD-10 and CCMD-Ⅲ as well as 35 health control subjects matched for education,age and sex were administered three tests for attention(sustained attention,Selective attention and Attention Blink).ResultsOn the Continuous Performance Test(CPT),depressed participants needed more reaction time and made more mistake than nondepressed participants.There were no differences between two block in reaction time in the CPT of patients and control subjects.The performance on the Stroop Color-Word Test was impaired in depression.Compared with normal subjects,depressed participants presented increased choice reaction times(CRT).Stroop interference was higher in depressed patients than in controls.On Attention Blink(AB) paradigm,both groups performed equally well at reporting the first target appearing in a rapidly presented stream of stimuli.All groups showed an AB,and AB for depressive participants were larger and longer.Correlations were observed between the HAMD score and the reaction time in CPT.ConclusionThe depressive participants showed a decrement tendency in vigilance,a higher Stroop interference and a larger and longer AB.

AIM:Investigating the expression of HIF-1α,apoptosis of retinal cells and the role of HIF-1α in apoptosis in rats' retinal ischemia-reperfusion injury.METHODS:The rat model of experimental retinal ischemia-reperfusion injury was established by increasing the intraocular pressure to 110mmHg(1kPa=7.5mmHg)in rat eyes.At different time points of post ischemia,the expression of HIF-1α of the retina was detected by immunohistochemicalstaining,and apoptosis of the retinal cell was detected by terminal deoxynudeotidyl transferase medialed deoxyuridine triphosphatebiotin nick end labeling(TUNEL).RESULTS:HIF-1α appeared in the cells of retinal ganglion layer and inner nuclear layer at 2 hours after ischemia.The expression reached to a peak,12 hours after retinal ischemia-reperfusion,then the expression was dedined.The apoptotiC Cells were mainly in inner nuclear layer and could be detected at the 12th, 24th and 48th hour after ischemia,the peak value was the group of 24th hour.CONCLUSION:Expression of HIF-1α in the rats' retina is greatly enhanced after ischemia-reperfusion,which may be involved in the retinal injury:the injury of retinal neurons Occurs partly in the form of apoptosis.The expression of HIF-1α may play an important role in cell apoptosis.

Objective To investigate the changes of serum apolipoprotein M (ApoM) level in cord blood and pregnant women during different gestational periods and to explore the relationship with the occurance and development of gestational diabetes mellitus (GDM).Methods Three hundred and eight pregnant women performing regular prenatal examination were registered in Changzhou Women and Children Health Hospital from June,2011 to April,2013,including 99 normal pregnant women during the second trimester,122 during the third trimester,and 87 pregnant women with GDM.At the same time,100 samples of cord blood of normal neonates were collected.The levels of serum ApoM and other lipids were measured.Results (1) Serum ApoM levels in pregnant women during the second trimester,during the third trimester,and in the cord blood of normal neonate were (0.036-± 0.013) g/L,(0.023 ± 0.008) g/L,and (0.010 ± 0.004) g/L,respectively.(2) The serum ApoM level of GDM group was lower than that of control [(0.029 ± 0.010 vs 0.036 ± 0.013) g/L,P＜0.05].Multivariate non-conditional logistic regression analysis showed that there was statistically significant difference in ApoM levels between GDM and control groups after adjusting for potential confounders (Z =-3.62,P＜0.05).Conclusions The level of serum ApoM in pregnant women was increased at first and then decreased.The serum ApoM level in the neonatal cord blood was significantly lower than that in pregnant women.The level of serum ApoM was lowered with raised blood glucose level in women with GDM,suggesting that ApoM might play a role in the pathological processes of GDM.

ObjectiveTo investigate the expression levels of the type Ⅰ IFN system in muscle and lung of experimental autoimmune myositis (EAM) model and to evaluate whether the type Ⅰ IFN system associates with the pathogenesis of the EAM model in rats.MethodsThe EAM model was established to determine creatine kinase (CK) in blood serum.The pathology of muscle and lung tissue was examined by hematoxylin-eosin staining.The concentration of type Ⅰ IFN system mRNA in muscle and lung tissue was detected by real-time PCR.ResultsThe concentration of CK in model group [(209.17 ±91.95) IU/L]was significantly higher than that of two control groups(P ＜0.05).The scores of muscle and lung in EAM model were significantly higher than that of control groups (all P ＜ 0.05).The expression levels of the type Ⅰ IFN system in muscle of EAM model were significantly higher than that of control groups(all P ＜0.05).The expression levels of the type Ⅰ IFN system in muscle with EAM model were positively correlated with CK and the scores of muscle (all P ＜ 0.05).The expression levels of IFNα, IFNβ, IFNαR1, signal transducer and activator of transcription 1 (STAT1), myxovirus resistance protein 1 (MX1) in lung of EAM model were significantly higher than those of control groups(P ＜ 0.05), but not seen in INF-induced protein with tetratricopetide repeats 1 (IFIT1) and IFN-stimulated gene 15 (ISG15).The expression levels of IFNα, IFNβ, IFNαR1, STAT1 and MX1 in lung with EAM model were positively correlated with the scores of lung pathology (all P ＜ 0.05).ConclusionThe type Ⅰ IFN system probably played a crucial role in the pathogenesis and the pathology of muscle and lung of EAM modeL

Aim To investigate the effects of pyrrolidine dithiocarbamate (PDTC) on D-galactosamine/lipopolysaccharides (GalN/LPS)-induced acute apoptotic liver injury and its mechanism.Methods All mice were randomly divided into four groups.Mice in GalN/LPS group were co-injected with GalN (600 mg·kg~(-1),ip) and LPS (20 μg·kg~(-1), ip). Mice in PDTC+GalN/LPS group were injected with two doses of PDTC,one (100 mg·kg~(-1), ip) at 24 h before LPS and the other at 2 h before LPS (20 μg·kg~(-1), ip).Mice in control groups were treated with PDTC (100 mg·kg~(-1), ip) or saline. Ten mice in each group were observed for animal survival within 72 h after LPS treatment. Six mice in each group were sacrificed 1.5 h after LPS for collecting blood and isolating livers. The expression of hepatic TNF-α mRNA was determined by reverse transcription and polymerase chain reaction (RT-PCR). Hepatic nuclear factor-κB (NF-κB) binding activity was measured with electrophoretic mobility shift assay (EMSA).Twelve mice in each group were sacrificed 8 h after LPS treatment. Serum was collected for measurement of alanine aminotransferase (ALT) and hepatocellular apoptosis and histological examination.Results Co-injection of GalN and LPS markedly increased serum ALT activity. Histopathological examination of liver sections revealed that GalN/LPS induced hepatic congestion, necrosis and massive macrophages infiltration, and increased the number of TUNEL-positive cells in mouse liver.GalN/LPS treatments, led to 90% mortality within 72 h with severe congestion and necrosis in the liver of all the dead mice. PDTC pretreatment significantly inhibited GalN/LPS-induced hepatic NF-κB activation and TNF-α expression. In contrast, PDTC aggravated GalN/LPS-triggered hepatocellular apoptosis, increased serum ALT activity, exacerbated hepatic hemorrhage and necrosis, and accelerated death.Conclusion PDTC aggravates GalN/LPS-induced acute apoptotic liver injury via inhibiting NF-κB-mediated anti-apoptotic effects.
