Objective To study the effect of astrocyte on synapse formation and the molecular mechanism. Methods Cortical astrocytes were isolated and purified from neonatal rats.On the 2h,7th day,14th day and 21th day after passage,we counted the number of astrocytes and the culture medium(astrocyte-conditioned medium,ACM)was harvested to measure the concentration of estrogen(E 2)by using ELISA techniques.Based on the model of pure culures of neonatal cortical neurons,the experimental groups were designed as follows:1.pure neuron cultures(group N);2.ACM cultures(group A);3.mixed cultures(group M);4.E 2 cultures(group E 2);5.ACM+Tamoxifen(estrogen receptor antagonist)cultures(group A+T);6.Tamoxifen cultures(group T).Then synaptic puncta in every group was stained and counted through immunofluorescence,and we also compared the differences in puncta number among those six groups(at 9th day in culture,number/per neuron). Results The numbers of astrocytes were:1?10 4/ml, 1.1?10 6/ml, 1.4?10 6/ml, 1.5?10 6/ml; The concentrations of E 2 were:(ng/L):0, 117?22, 266?22,252?27 respectively.No estrogen was detected in the primary culture medium.The concenteration of estrogen increased in correspondence with the culturing days and reached the peak around at the 14th day, then decreased gradually but kept at a certain high level,and the numbers of synaptic puncta of per neuron in group N,A,M,E 2,A+T,T were:14?3;79?5;83?8;80?6;32?3;29?3 respectively.The treatment of pure neuron culture with ACM increased the number of synapses on per neuron by up to 6 fold by comparison with pure neuronal culture.Exogenic estradiol added into pure neurons can mimick the effect of the ACM.Tamoxifen which is antagonist of estrogen receptor could decrease the effect of ACM by 75%.Conclusion The astrocytes of neonatal rat cortex do secrete E 2.Astrocyte-derived estrogen may be the molecule regulating the synaptic formation through estrogen receptors.

Objective To measure the estrogen concentration of estrogen (E 2) in the culture medium of rat astrocytes (ASTs). Methods Astrocytes in brain cortex of the 2-day-old neonatal rats were collected and cultured. The number of astrocytes was counted and the concentration of estrogen was measured by ELISA method at 0, 7, 14, and 21 d after culture. Results The cell counts were 1?10 4/ml, 1.1?10 6/ml, 1.4?10 6/ ml, and 1.5?10 6/ml, respectively. The concentrations of E 2 were: 0 pg/ml, (117.03?21.32) pg/ml, (266.91?22.03) pg/ml, and (252.62?27.99) pg/ml, respectively. No estrogen was detected in the primary culture medium. The concentration of estrogen increased in a time-dependent manner and reached the peak at 14 d, and then decreased gradually but remained at a certain level. Conclusion E 2 is secreted by astrocytes in the brain cortex of the 2-day-old neonatal rats.

Objective To study the effect and the mechanism of astrocytes-derived estrogen on synaptic transmission. Methods Based on the model of pure cultures of neonatal cortical neurons, the experimental groups were designed as follows: pure neuron culture (group P), ACM culture (group A), mixed culture of AST and neuron (group M), E_ 2 culture (group E), ACM+tamoxifen (estrogen receptor antagonist) culture (group A+T ), tamoxifen culture (group T). The difference among these groups of synaptic transmission was recorded by patch clamp and presynaptic vesicle releasing kinetics was marked by a dye named FM4-64. Results The mean amplitude and frequency of miniature postsynaptic currents (mPSCs) of group P, A, M, E, A+T and T were: (20.5?2) pA, (13?4) min -1 ; (29.1?3) pA, (73?16) min -1 ; (31.3?3) pA, (78?20) min -1 ; (30.2?3) pA, (76?18) min -1 ; (24.5?2) pA, (35?10) min -1 ; (22.1?2) pA, (37?10) min -1 respectivily. The treatment of pure neuron culture with ACM increased synaptic transmission of pure cultured cortical neuron. Exogenic estradiol added into pure neurons can stimulate the effect of the ACM. Tamoxifen which was the antagonist of estrogen receptor could decrease most effect of ACM on synaptic transmission. The assaying of vesicle release marked by FM4-64 showed astrocytes-derived estrogenic enhancing synaptic transmission was at least mediated by strengthening presynaptic vesicle releasing. Conclusion The estrogen from astrocytes of neonatal rat cortex may enhance neuronal synaptic transmission mainly through estrogen receptor.

The setup of clinical education nurses had the advantages as follow: First, the clinical health education with high levels and high qualities can effectively strengthen the patients attending consciousness;second,scientific trainings of health education nurses were useful to pre control the qualities of the health education and improve the level; At last, respecting and caring for patients were the key points to make the patients satisfy the health education.

OBJECTIVE:To prepare Idebenone solid dispersion,and to investigate its dissolution rate in vitro. METHODS:Us-ing Poloxamer 407(P407)as carrier,the influence of preparation methods(solvent method,melting method)and the ratio of the drug to P407(1∶1,1∶3,1∶8)on the dissolution of drug were investigated by single factor design. The state of idebenone in ma-trix of solid dispersion was further determined by using differential scanning calorimetry (DSC) and X-ray powder diffraction (XRD). RESULTS:Idebenone solid dispersion prepared by solvent method(the ratio of the drug to poloxamer was 1∶3)showed dissolution rate of 80%. The majority of idebenone existed in the solid dispersion at amorphous forms or molecular state. CONCLU-SIONS:Idebenone solid dispersions with high dissolution rate in vitro is prepared successfully.

OBJECTIVE：To study the therapeutic effect and safety of domestic tolterodine tartrate in treating patients with urinary bladder overactivity.METHODS：56 cases of bladder overactivity were divided into two groups randomly：tolterodine and control(oxybutynin)group.The course of treatment was 6 weeks.RESULTS：The effect of tolterodine in treatment group was comparable to that of oxybutynin in control group,however,the adverse reactions in oxybutynin group were more common than those in tolterodine group.CONCLUSION：Tolterodine is a suitable drug to treat bladder overactivity.

Objective To retrospectively investigate the clinical features of localized primary small bowel stromal tumors (SBSTs) and the impacting factors for prognosis.Methods The clinical and pathological data of 89 consecutive SBSTs patients,with pathologically confirmed,who underwent complete resection in Ruijin hospital between January 2003 and September 2007 were collected and analyzed.All patients were followed up for assessment of tumor recurrence and metastasis.The impacts of clinical and pathologic factors on rate of disease free survival (DFS) of the patients was evaluated.Results In total of 89 follow-up patients,15 patients were diagnosed with tumor recurrence and 9 of them died.The tumor size,mitotic index and pathological risk stratification were statistically related with DFS (P=0.000,P=0.006,P=0.000,respectively) by using Kaplan-Meier univaritate analysis.Tumor size and mitotic index were proved to be independent prognostic factors for tumor recurrence by multivariate analysis COX regression model.Conclusions Tumor size and mitotic index are related with tumor recurrence,and can be regarded as independent predictive factors of tumor recurrence.

Objective Because of the major trauma from thoracotomy , postoperative pain may arouse patients'psychological and physiological stress response and hence affected the treatment outcome and functional recovery seriously .We retrospectively studied the correlation between the staging of pain and nursing interference to investigate the effect of nursing interference on the pain intensity after thoracic surgery . Methods Five hundred and eighty cases of patients surviving thoracotomy between December 2013 and March 2014 in Nanjing Jingling Hospital were reviewed .Correlations between comfortable nursing measures such as effective analgesia , postural care , catheter care , environmental interventions , psychological intervention and the standard assessment of pain were analysed according to postoperative pain stage . Results With comprehensive nursing interference , the highest pain score occurred in the first 24 hour (2.89 ±0.39).The score was reduced gradually to 2.25 ±0.90 in stage Ⅱ, 1.58 ±0.57 in stage Ⅲ and 1.06 ±0.24 in stage Ⅳrespectively . Conclusion Comprehensive nursing interference according to pain staging may relieve pain effectively after thoracotomy .
