Objective To observe changes of apoptosis and Caspase-12 expression in hippocampus of the rat model of posttraumatic stress disorder ( PTSD ) .Methods Single prolonged stress ( SPS ) was used to duplicate a rat model of PTSD.Male Wistar rats were randomly divided into 1, 4, 7 days groups after exposure to SPS and a normal control group.Transmission electron microscopy was used to observe morphologic changes of the hippocampus neurons .The expression of Caspase-12 was detected by immunohistochemistry , Western blotting and RT-PCR.Results After SPS, the hippocampus neurons had characteristic morphologic changes of apoptosis , and the expression of Caspase-12 reached the peak at SPS 4d.Conclusion PTSD activates the ERS-mediated apoptosis in hippocampus via Caspase-12, which may be a pathophysiology base of the atrophy of the hippocampus in PTSD .

Investigate the effect of prestorage white cell filtration on the cytokines content in blood. Methods: Ten units of whole blood was divided into two parts just after blood collection:one was used as control, the other was filtrated by leukoreduction filters. All units were stored at 4℃ for 6 weeks. Immediately after filtration and every week subsequently, samples for analses of IL-2, IL-8 were obtained. Results:The amounts of IL-2 and IL-8 increased during the storage period. In filtered units, the amounts of IL-8 did not increase during the study period, IL-2 still increased but was still lower than that of unfiltered units at the end of storage. Conclusion: Many cytokines, such as IL-2 and IL-8, were generated and accumulated in blood during blood storage. Leukocyte filtration may prevent this effect to some extend. Prestorage filtration may decrease FNHTRs by preventing the accumulation of cytokines in blood.

Monoamine oxidase A (MAOA) can catalyze the degradation of a variety of amine neurotransmitter,including serotonin.The abnormalities of these neurotransmitter are closely associated with many psychiatric disorders.Studies have found that MAOA is polymorphic,with a low activity variant (MAOA-L),and a high activity variant (MAOA-H).In this review,through the studies of early stress on human and animal models,the effects of early stress and MAOA polymorphism on the behavior and emotional loop of individuals are analyzed.Analysis shows that,MAOA-L,versus MAOA-H,is more plastic.In early adverse environment,MAOA-L will increase the risk of adult violence,and in the early of energetically favorable environment will reduce the incidence of violence.Abnormality is more likely to occur in the emotional processing and cognitive function in the neural affective loop of individuals with MAOA-L,which makes them more environmentally susceptible than those with MAOA-H.

OBJECTIVE:To investigate the satisfaction degree of outpatients on policy of separation of clinical pharmacy from 4 third grade hospitals in Shanghai,and provide reference for promoting medical reform policy. METHODS:Parts of outpatients in the 4 new suburb third grade hospitals were investigated by the questionnaire and interview in Shanghai city,and the data was sta-tistically analyzed by Excel software and SPSS 19.0 software. RESULTS:Totally 400 questionnaires were sent out and 368 were valid with effective recovery of 94.3%. The awareness rate of medical separation policy was 81.3% in the outpatients;55.5% of outpatients thought that medicine cost savings effect was not obvious;the overall satisfaction of patients was 91.6%,and the high-est of satisfaction was the service attitude and the lowest was medical expenses. CONCLUSIONS:Policy of separation of clinical pharmacy has reduced the medical expenses,guided the triage treatment of patients partly and improved the satisfaction of patients. It is suggested to shorten the waiting time by optimizing examination process,strengthen price regulation in drug,standardize pro-duction and distribution process,improve use rate of essential medicines and promote clinical rational drug use for further improve-ment of satisfaction.

It is to investigate the effect of two kinds of Houttuynia Cordata Injection on preventing and treating H1N1 influenza virus infection in mice. Pneumonia model was set up by intranasal infection of the normal and immunocompromised mice with influenza virus FM1 and PR8. The two injections were administered before and after the administration of virus, separately, and the lung index was observed. The results showed that the two preparations have obvious therapeutic effect on normal mice infected with influenza virus FM1 and PR8. And to FM1, the new injection's effect is better at small dosage. The results also showed that the two preparations have obvious prophylactic effect on immunodepressed mice infected with influenza virus FM1 and PR8. And to PR8, the old injection's effect is better at small dosage. Houttuynia Cordata Injection can improve the mice pneumonia caused by influenza virus H1N1 and decrease the lung index markedly. It has a remarkable preventive and therapeutic effect on H1N1 influenza virus in mice.

Objective To predict the risk of neonatal hyperbilirubinemia by transcutaneous bilirubin (TcB) nomograms and clinical risk factors.Methods Healthy term and late-preterm newborns (≥ 35 gestational weeks,and birth weight ≥ 2 000 g) born in Guizhou Maternal and Child Care Hospital between January 1,2013 and December 31,2013,were included.TcB levels were continuously recorded within 168 hours after birth.The value of hour-specific TcB nomogram combined with receiver operating characteristic (ROC)curves and Logistic regression model for predicting risk of hyperbilirubinemia was evaluated.Pearson's Chisquare test was also used for statistical analysis.Results A total of 5 250 cases were enrolled.TcB increased rapidly in the first 40 hours after birth,slowly increased between 40 to 96 hours,and reached a high level after 96 hours.Among them,the 95th percentile TcB stablized at 96 hours after birth.The 40th,75th and 95th percentile TcB peak levels were 173,217 and 248 μmol/L.Among the 5 250 neonates,there were 277 cases (5.3％) in the high-risk zone within 72 hours.The positive predictive value (PPV) was 22.02％;1 087 cases (20.7％) and 1 854 cases (35.3％) were in the medium-high risk and medium-low risk zones along with the PPV of 10.58％and 3.72％,respectively.There were 2 032 cases (38.7％) in the low-risk zone with the PPV of 1.38％.Multivariate analysis showed that the TcB high-risk zone after 72 hours was associated with gestational age,delivery mode,feeding mode and TcB level of risk zones within 72 hours.Compared to those born at ≥ 40 gestational weeks,those born at ≥ 37-＜40 gestational weeks were more likely in the TcB high-risk zone after 72 hours (OR=1.80,95％CI:1.29-2.51).The likelihood was reduced by 42％ among neonates born with cesarean section compared to those delivered vaginally in term of the TcB high-risk zone after 72 hours.Infants who received mixed feeding were less likely to be in the TcB high-risk zone after 72 hours when compared to breastfed infants (OR=0.51,95％CI:0.29-0.88).With the reduction of the high-risk zone level within 72 hours,the likelihood in the TcB high-risk zone after 72 hours was also decreased.ROC curve showed that the area under the curve (AUC) for predicting hyperbilirubinemia was 0.75 and its 95％CI was 0.72-0.78,with a sensitivity of 90.00％ and specificity of 40.00％.The AUC of a combination of predictive results obtained by the Logistic regression model with significant variables in univariate analysis and high-risk zone after 72 hours was 0.66,and its 95％CI was 0.62-0.69.AUC estimated by Logistic regression model according to the TcB levels of risk zones within 72 hours combining with clinical risk factors was 0.79,and its 95％CI was 0.76-0.82 (P＜0.01).Conclusions Hour-specific TcB nomograms of newborns in our hospital have been obtained,which facilitates the prediction and early intervention of neonatal hyperbilirubinemia.

Objective To investigate the relationship between the content of stromal cell-derived factor-1 (SDF-1) in myocardium in different period of myocardial infarction and left ventricular function.Methods Twenty three Chinese miniature pigs were randomly divided into the experimental group and the control group.The swines in experimental group were prepared as acute myocardial infarction model by ligating anterior descending coronary artery and were randomly divided into 6 subgroups according to the different time points after infarction.The left ventricular end-diastolic diameter (LVDd),left ventricular ejection fraction (LVEF) and left ventricular fraction shortening (LVFS) were measured respectively.Global circumferential strain (GCS) and global radial strain (GRS) of left ventricle were measured.The content of SDF-1 were also measured by real-time quantitative PCR.Results Compared with the control group,SDF-1 levels were significantly elevated,and LVEF,LVFS,GCS and GRS were reduced.However,LVDd were significantly increased.The content of SDF-1 and GCS has a negative correlation (r =-0.580,P =0.000).Conclusions The content of SDF-1 in myocardial tissue have a certain relationship with GCS of left ventricular myocardium.
