Tianjin Medical Journal 2016;44(6):783-785,786
Objective To evaluate the curative effects of venlafaxine in patients with depressive disorder between therapeutic modes of inpatient and outpatient. Methods Seventy-two patients with depressive disorder including 36 inpatients and 36 outpatients were measured respectively with HAMD24 after treatment for 1 week, 2 weeks, 4 weeks and 8 weeks, and then the curative effects were compared between two groups. Results It was found that all patients in the inpatient group completed the observation and two patients in the outpatient group didn’t complete the observation. The HAMD24 score was significantly decreased in the inpatient group than that of the outpatient group from the second week to the end of the eighth week (P<0.05). The total effective rates were 80.6% for inpatient group and 64.7% for outpatient group, no significant difference between them. Conclusion Venlafaxine shows a higher therapeutic value and outcome in the therapeutic mode of inpatient.

Objective To investigate the effect of estrogen replacement therapy applied in different periods to ovariectomized rats and to evaluate the cognitive function of the rats.Methods Totally 40 rats were ovariectomized to be postmenopausal models.They were divided into early hormone replacement therapy group (n =10,managed by estradiol valerate at day 3 after surgery),early control group (n =10,managed by saline at day 3 after surgery),late hormone replacement therapy (n =10,managed by estradiol valerate at day 90 after surgery for 30 days) and late control group (n =10,managed by saline at day 90 after surgery for 30 days).The behavior indicators of the rats were evaluated by Morris watermaze and hippocampal metabolite was detected by proton magnetic resonance spectroscopy,including N-acetylaspartate (NAA),choline containing compounds (Cho),creatine(Cr),myoinositol (mI),NAA/Cr,Cho/Cr and mI/Cr.Results (1) Navigation test: escape latency were (43 ± 13) s at the early control group,(28 ± 9) s at the early HRT group,(82 ±26) s at the late control group and (48 ± 18) s at late HRT group.Swimming distance were (1 404 ± 238) cm at the early control group,(878 ± 354) cm at the early HRT group,(2411 ±818) cm at the late control group and (1 310 ±434) cm at the late HRT group.The escape latency and swimming distance of the early and late HRT groups were significantly shorter than those at the control groups (P < 0.05).(2) Spatial probe test: the swimming time in the target quadrant of rats in the early HRT group (34.0 ± 3.0) s were longer than those in other groups (P < 0.05).(3) Proton magnetic resonance spectroscopy: NAA/Cr were 1.12 ±0.17 at the early control group,1.26 ±0.12 at the early HRT group,1.57 ±0.21 at the late control group and 1.38 ±0.28 at the late HRT group.The late HRT group and the late control group were higher than their early groups (F =6.05,P =0.040).There was no significant difference between the HRT groups and the control groups (F =0.04,P =0.860).mI/Cr were 0.69 ±0.04 at the early control group,0.46 ±0.12 at the early HRT group,0.70 ±0.03 at the late control group and 0.75 ± 0.08 at the late HRT group.There were statistically significant differences of the experimental time between the early and late groups(F =16.45,P =0.004).The differences between the early HRT group and the early control group,and the late HRT group and the late control group were significant(F =6.01,P =0.040).And there was an interaction with the experimental time and HRT measures (F =13.79,P =0.006) ; early HRT can reduce the average level of mI/Cr.Cho/Cr were 0.95 ± 0.09 at the early control group,0.80 ±0.12 at the early HRT group,0.87 ±0.09 at the late control group and 0.85 ± 0.12 at the late HRT group.There was no significant difference among those groups (P >0.05).NAA/mI: there was an interaction with the experimental time and HRT measures (F =12.95,P =0.007).Early HRT can elevated levels of NAA/mI,while the late results were reversed.Conclusion Earlier estrogen replacement therapy may play a positive role in improving cognitive function of the ovariectomized rats.

Objective To investigate the application value of real clinical case centered situation simulation examination model in clinical medicine. Methods Two classes were randomly selected from 2008 grade clinical medicine majors, respectively as test group(n=158) and control group(n=156). Final examination of test group includes usual performance, case-oriented situation simulation examination (COSSE) and final written examination. Traditional methods were used in control group. The same paper was used in final written examination of the two groups. Scores of written examination and question-naires were used to evaluate the COSSE model. Data were processed using SPSS 16.0 statistical software;t and chi-square tests were used to analyze the data;P<0.05 signifies that the difference is statistically sig-nificant. Results Scores of final examination in test group were higher than those in control group(P<0.001). Times of independent completion of history taking, physical examinations and medical record writing were more in test group than in control group(P=0.002,0.017,0.048). Conclusions Contents and methods of COSSE is conducive to improving student's professional comprehensive ability.

Objective To evaluate the changes of thyroid function during pregnancy in the second and third trimester in the regions with or without iodine deficiency. Methods The serum TSH, FT 3, FT 4 and TT 4 levels of 90 pregnant women (30 from iodine deficient area as study group, 60 from iodine sufficient area as control group) and 30 non pregnant women were assayed by high sensitive immunoradiometric assay (IRMA) or radioimmunoassay (RIA), and urine iodine level of pregnant women before delivery was also examined. Results (1) The serum TSH level in pregnant women in the second and third trimester was significantly higher than that of non pregnant women. The serum free thyroid hormone levels of pregnant women were significantly lower than that of non pregnant women, especially in the third trimester. (2) The serum TSH level of pregnant women from iodine deficient area in the second trimester and before delivery was significantly higher than that of pregnant women from iodine sufficient area (P

Objective To explore the correlation of NT‐proBNP concentration and the fluid infusion volume in the patients with severe burn ,and to evaluate the significance of monitoring NT‐proBNP in severe burn patients .Methods Fifty cases of severe burn in 100 Hospital of PLA form September 2012 to September 2015 were selected ,without major disease history and genetic history before admission ,among them ,25 cases(group A) had the burned area 35% -50% TBSA or Ⅲ degree 10% -20% TBSA ,18 cases (group B) had the total burn area of >50% TBSA or Ⅲ degree >20% TBSA for group B and 10 cases(group C) had the total burn area>90% and were composite explosive injury .The NT‐proBNP concentrations were monitored on 1-30 d after admission for guiding blood transfusion and fluid infusion;contemporaneous age‐matched 53 patients with plastic surgery were selected as the control group .Compared with the calculation formula of the fluid volume ,the guiding advantage of NT‐proBNP was analyzed .Re‐sults The practical fluid volume in these burn patients were higher than that calculated by the common fluid replacement formula . The more severe burn ,the higher the NT‐proBNP concentration and the more blood products were demanded;the NT‐proBNP con‐centration ,fluid infusion volume ,MAP infusion volume and PLT transfusion volume had statistical difference between the group C and B and between the group B and A (P<0 .05) .Conclusion The NT‐proBNP concentration change may have a higher guidance and early warning significance for middle and long term rational control of blood transfusion and fluid infusion volume in the pa‐tients with severe burns .
