Chinese Journal of Medical Education Research 2011;10(6):683-685
To survey the time management disposition of the medical postgraduates,the Time Management Disposition Scale were used on 774 medical postgraduates for investigation in 2009. The difference of medical postgraduate from the countryside,towns and cities on time management disposition is not significant ( P>0.05 ) ; Students of different gender have significant difference ( P<0.05 ). The female postgraduates cultivation on time management disposition needs to be strengthened.

[Objective]To explore the clinic results of bi-posterolateral fusion combined with coralline hydroxyapatite interbody fusion,a three point stable spine fusion technique in the treatment of degenerative vertebra disc disorder.[Method]Bi-posterolateral fusion combined with posterior interbody fusion were performed to treat 41 cases of degenerative vertebra disc disorder from August 1998 to August 2006.The patients included 18 men and 23 women;their average age was 48 years.The slippage and grade of spondylolisthesis before and after spine fusion were investigated.The severity and slippage of radiographic measurements were also recorded,along with the average follow up of 19.1 month(range 12-48 months).The three point spine fusion applied autologous bone chips for bi-posterolateral fusion and one cubic block of coralline hydroxyapatite for anterior inter body fusion which achieved by PLIF technique.[Result]In the 41 patients who had underwent three point spine fusion surgery,only 1/41 patients experienced nerve root pain after surgery,and in most cases clinical symptoms were improved greatly.In 21/41 patients who had severe lower back pain completely disappeared after surgery,and in 9/41 cases these symptoms were minimal.The clinical evaluation according to the symptoms before the operation was excellent 2.4%(1/41),good 19.5%(8/41),fair 21.9%(9/41),bad 56.1%(23/41);after operation excellent 68.3%(28/41),good 29.2%(12/41),fair 2.4%(1/41),bad 0.0%(0/41).A radiographic measurements showed the anterior disc height was 8.05?2.35mm before operation and 11.44?3.38mm after operation(P

Objective To study the protective effect of nalmefene hydrochloride on lung ischemia-reperfusion injury and its mechanism.Methods 40 rats were randomly divided into model group,high dose of nalmefene group,low dose nalmefene group and sham operation group equally(n =10).The lung ischemia-reperfusion model was established by occlusion of the left pulmonary hilum.The intravenous injection of nalmefene (20,10 μg·kg-1) was applied at 10 minutes before occlusion of the left pulmonary hilum in the high dose of nalmefene group and the low dose of nalmefene group,respectively.The sham operation group without occlusion of the left pulmonary hilum was not given any treatment.At 2 h after reperfusion,all rats were detected arterial blood gas value and then sacrificed.The specimens from the upper lobe of the left lung tissue were preserved to observe pulmonary lesions,detect the ratio of wet / dry weight and the expressions of β-endorphin and interleukin(IL)-17.Results Compared with the model group,the value of PCO2,the degree of pulmonary lesions,the ratio of wet / dry weight and the expressions of β-endorphin and IL-17 in lung tissue were significantly decreased (P < 0.01),while the value of PO2 was significantly increased (P < 0.01) in the low dose of nalmefene group.Compared with the low dose of nalmefene group,thevalue of PCO2,the degree of pulmonary lesions,the ratio of wet/dry weight and the expressions of β-endorphin and IL-17 in lung tissue were significantly decreased (P < 0.01),while the value of PO2was significantly increased (P < 0.01) in the high dose of nalmefene group.Conclusion Nalmefene hydrochloride may prevent lung ischemia-reperfusion injury in a dose dependent manner by reducing the production of β-endorphin and inhibiting the expression of IL-17 in lung tissue.

Objective To investigate the intermediary effect of depression between housebound and cognition in community-dwelling older adults and to provide intervention for the improvement of the life quality.Methods A total of 720 senior adults were selected to fill out demographic questionnaire,including Rasch-Derived Center for Epidemiological Studies Depression Scale (CES-D-R),housebound scale and the minimental state examination (MMES).Results The depression score of the elderly in community was (3.95±4.12),housebound score was (4.26±1.23),cognition score was (21.52±4.04) and the incidence rate of the cognitive disorder was 37.1%.Cognition was significantly negatively related to housebound and depression (r=-0.409,P<0.01;r=-0.485,P<0.01).Housebound was significantly positively related to depression (r=0.555,P<0.01).The community elderly age,sex,marital status,degree of education,self-assessment of health,living space,depression and the housebound could be used to predict the cognitive function,and all of them could explain the variance of cognitive function of 50.8%(P<0.05).Housebound had a direct effect of-0.02 on cognitive function(P>0.05).The indirect effect of housebound on cognitive function through depressive mood was-0.45(P<0.05).Conclusions The elderly housebound has an intermediary effect on the cognitive function through the depression.

The perioperative total serum CK and CK-MB activities were determined in 38 patients with carcinoma of the esophagus and cardia of the stomach with fluorometric and cylinder layer chromatography. The data were compared with those obtained from 18 patients undergoing pulmonary operation and 20 normal subjects. The results suggest that: (1) carcinoma of the esophagus and cardia of the stomach could not induce variation of the total serum CK and CK-MB; (2) the elevation of the total serum CK after esophagogas-trostomy might probably be due to the trauma of the skeletal muscles of the chest wall;(3)the total serum CK is non-specific for the diagnosis of AMI in the perioperation period,but CK-MB might be considered as a specific enzyme criteria.

Objective To investigate the pharmacokinetics ( PK ) and pharmacodynamics ( PD ) processes of rabeprazole in inhibiting gastric acid secretion with the combined PK-PD model. Methods A total of 10 healthy volunteers were given a intravenous infusion of 20 mg rabeprazole over a 30-min period. The concentration of rabeprazole in the plasma at different time points was detected by HPLC,and the PK parameters were calculated by DAS 2. 0 software. At the same time the intragastric pH was monitored over 24 hours to fit the PD parameters with indirect inhibition model. Results The main PK parameters,t1/2,Cmax,and AUC were(60. 5±17. 3)min,(1 299. 1±201. 0)ng·mL-1,and(106. 4±26. 0)mg·min·L-1, respectively.The corresponding PD parameters,Kin,Ke,IC50 and Imax were(8.200±3.362)h-1,(1.080±0.378)h-1,(0.286± 0. 129)mg·L-1 and(6. 93± 2. 15)pH,respectively. Conclusion The PK of rabeprazole in healthy volunteers conforms to one compartment model,and the PD fits the indirect response inhibition model. The equation can effectively establish the relationship between the blood drug concentration and the effect.

Objective To investigate the changes and significance of the contents of cholecystokinin (CCK) acceptors and nitric oxide synthase (NOS) in sphincter of Oddi and the contents of CCK and nitric oxide (NO) in the blood of the patients with calculus of bile duct. Methods The contents of CCK acceptors and NOS in sphincter of Oddi and the contents of CCK and NO in the blood were determined in 41 patients with gallstone and 6 controls. Results The contents of CCK and NO in the blood of patients with gallstone were significantly higher than that in control [ ( 38.91±4.85 ) pmol/L vs ( 30.67±1.81 ) pmol/L; (40.84±4.74 ) pmol/L vs ( 32.81±1.11) pmol/L] ;The contents of CCK acceptors and NOS in sphincter of Oddi in the patients with gallstone were signifi-cantly lower than in the controls [ (67.59±5.87 ) ng/L vs ( 78.99±1.71 ) ng/L; ( 457.52±45.40 ) ng/L vs ( 519.61±11.38 ) ng/L] ;The contents of CCK and NO in the blood in the different groups with calculus of bile duct were significantly different from those in the controls. Conieusion The degree of the decrease of the contents CCK acceptors and NOS in sphincter of Oddi leads to the decrease of Oddi sphincter function,resuting in cholestasis and promoting the formation of bile duct stone.

Bile duct stone is the common and frequently-occurring disease, its incidence upwards trend. In recent years, people realize that Oddi sphincter movement disorders play an important role in the inci-dence of bile duct stones. NO, CCK, VIP and theie interactian have effects on sphincter function and dis-charged from the regulation of bile. These factors are necessary to conduct an in-depth study to investigate the cause of bile duct stone and its treatment.
