0.37).Meanwhile a good correlation (Y=0.99X-0.18,r=0.987) was obtained. Though Westergren method correlated preferably with MICROTEST 1 (Y=0.86X+1.27,r=0.906),there was a markedly different (t=3.174,P=0.001).At last different references values were collected, according to sex and age.Male,32.5 mm/1 h(60 years old);Female, 34.03 mm/1 h(50 years old).Conclusions MICROTEST 1 correlated preferably with Westergren method.The examination by MICROTEST 1 needs small quantity of sample and fewer time.Furthermore,it has good repeatability and stability.The factors such as temperature and Hct have little influence on the results.The result suggested that it is suitable to apply MICROTEST 1 to large- scale clinical laboratory or other labs.But the reference value of ESR was influenced by age,which should be considered in clinical usage.

OBJECTIVE: To realize the automated assessment of the levels of epiphysis of distal radius and ulna by support vector machine (SVM). METHODS: The X-ray films of the left wrist joints were taken from 140 teenagers aged from 11 to 19 years old as training samples. The levels of epiphysis of distal radius and ulna were divided into five developmental levels. Each level contained 28 samples. Another 35 cases were selected as independent verifying samples. SVM classification models of the five developmental levels of epiphysis of distal radius and ulna were established. The internal cross validation was made by leave one out cross validation (LOOCV), while the external validation was made by histogram of oriented gradient (HOG), and then the accuracy (PA) of testing results was calculated, respectively. RESULTS: The PA of SVM, LOOCV and HOG of distal radius epiphyseal level were 100%, 78.6%, and 82.8%, respectively; whereas the PA of SVM, LOOCV and HOG of distal ulna epiphyseal level were 100.0%, 80.0% and 88.6%, respectively. CONCLUSION The SVM-based automatic models of the growth stage of distal ra- dius and ulna appear to have certain feasibility, and may provide a foundation for software development of bone age assessment by forensic medicine.

OBJECTIVE: To explore the change rules of peak area ratio of STR loci to Amelogenin (AMEL) locus (STR/AMEL), a sex-determining gene in DNA degradation, and to evaluate the application of STR/AMEL value in the estimation of DNA degradation degree. METHODS: DNA was extracted from iliopsoas, and the variations of STR/AMEL value (Penta E/AMEL, Penta D/AMEL, FGA/AMEL) were analyzed after the artificial degradation was made by DNase I, and the changes of these three ratios of the iliopsoas naturally degraded in an outdoor environment were also analyzed. The regression curves were analyzed using the periods of DNA degradation and outside the body as the independent variable (x) and the STR/AMEL value as the dependent variable (y) and three curve equations under two conditions were established. RESULTS: Both under the conditions of artificial and natural degradation, STR/AMEL value had a negative relationship with the degradation time. The relationship between STR/AMEL and degradation time can be well simulated by the cubic function. R2 was over 0.99 under controlled degradation condition and over 0.86 under natural degradation condition. CONCLUSION The STR/AMEL value (Penta E/AMEL, Penta D/AMEL, FGA/AMEL) is negatively related with the DNA degradation degree, which follows mathematical regression models strictly, and it might be applied to evaluate the DNA degradation degree.

Objective:To investigate the effect of Bifidobacterium combined with ulinastatin on the immunologic function of sepsis rats.Methods:One hundred male SD rats were randomly divided into sham-operated group,model group,Bifidobacterium treatment group,Ulinastatin treatment group,combining treatment group.Cecal ligation and punctured was used to prepare sepsis model in rats.Survival rate was observed.The number of intestinal floras were determined.The tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6)were tested by enzyme linked immunosorbent assay (ELISA).T-lymphocyte subset was tested by flow cytometry.Serum endotoxin was tested by TAL method.Results:Serum endotoxin,Escherichia coli,CD8+T cell,TNF-α and IL-1β of model group were significantly higher than the sham operation group (P＜0.05).CD3+,CD4+T cell and ratio of CD4+/CD8+T cell,Bifidobacterium and lactobacillus were significantly higher than the sham operation group (P＜0.05).Compared with model group,Serum endotoxin,Escherichia coli,CD8 +T cell,TNF-α and IL-1 β of combining treatment group were significantly decrease (P＜0.05).CD3+,CD4+T cell and ratio of C D4+/CD8+T cell,Bifidobacterium and lactobacillus were significantly increase (P＜0.05).Serum endotoxin,TNF-α and IL-1 β of combining treatment group were significantly lower than that in Bifidobacterium treatment group and Ulinastatin treatment group.CD3+,CD4+T cell and ratio of CD4+/CD8+T cell,Bifidobacterium and lactobacillus were significantly higher than that in Bifidobacterium treatment group and Ulinastatin treatment group.Conclusion:Efficacy is significantly improvement while Bifidobacterium combined with ulinastatin,which can restrain TNF-α and IL-6 of CLP rats,decrease the increasing of serum endotoxin,and regulate the balance of intestinal floras,also improve the immune function of CLP rats.

OBJECTIVETo assess the co-morbidity of anxiety and depression in hospitalized patients and to analyze the degree of symptoms and the influential factors.

METHODSThirty patients with malignant tumor were injected with thymosin alpha 1 subcutaneously at the dose of 1.6 mg q.d. for the first month and q.o.d. for the following month. The number of T cell subgroups and the activity of NK cell in peripheral blood were detected and the quality of life of the patients were evaluated before treatment and at the end of treatment.

RESULT(1) About 39.9 % of the patients presented the symptoms of anxiety and depression and out of them 6.7 % were taken psychotropic medication. (2) Stepwise Logistic Regression showed that the factors related to anxiety and depression could be classified into four categories: economic factor, sleeping status, cognition of disease, the other factors such as course of disease and the environment of hospital. (3) Data analysis of oncology patients showed that the cognition of disease would be an important factor, which would affect anxiety and depression status.

CONCLUSIONMultiple factors can affect anxiety and depression symptoms of inpatients. The results suggest that psychological intervention such as cognitive therapy should be considered in clinical practice.

The phytase gene phyA(m) from Aspergillus niger N25 was recombined into E. coli expression vector pET-30b(+). Recombined at expression vectors pET30b-FphyA(m) was served as a template to amplify phytase gene, and the PCR product named elongation mutation gene phyA(e) was expanded with a 13 amino acid sequence from pET-30b-FphyA(m) vector at C-terminal of phytase gene phyA(m). Furthermore, phyA(e) gene was recombined into expression vector pPIC9k and expressed in Pichia pastoris. The comparison experiment of mutant phytase PP-NP0 with wild-type phytase PP-NP(m)-8 showed that: the optimum temperature of PP-NPe was increased by 3 degrees C, and its thermostability was increased by 21% when it was exposed to 10 min at 75 degrees C. Its effective reaction pH range with catalysis efficiency above 70% was pH 4.6 - pH 6.6, and wider 0.4 pH value than that of wild-type phytase.

OBJECTIVETo explore the mechanism of cake-separated moxibustion in treatment of hyperlipemia.

METHODSSixty rabbits were randomly divided into 4 groups, a blank group,a model group, a direct moxibustion group and a cake-separated moxibustion group. Hyperlipemia model was developed by high fat diet of cholesterol. Changes of ultrastructures of endothelial cells of the aorta of the rabbit were observed with electron microscope.

RESULTSThe endothelial cells in the cake-separated moxibustion group were more intact, most of them were normal in forms, internal elastic membrane was continuous, their thickness was even, the cells of smooth muscles in the medial membrane were relatively normal, which are similar to those in the blank control group. But the structure of endothelial cells of the aorta in the model group disappeared, in cytoplasm the sedimentation of a great number of lipids can be seen, internal elastic membrane was interrupted, the thickness was uneven, with focal dissolution, the cells of smooth muscle in the medial membrane had sedimentation of lipids, with frothy change.

CONCLUSIONCake-separated moxibustion has a certain protective action on endothelial cells of the aorta in the rabbit of hyperlipemia.

OBJECTIVETo observe the efficacy of intravenous scopolamine in the prevention of postoperative nausea and vomiting (PONV) after cesarean section (CS).

METHODSA total of 260 pregnant women with American Society of Anesthesiologists (ASA) Physical Status Classification class I-II who underwent elective CS under combined spinal-epidural anesthesia (CSEA) were randomly divided into four groups (n = 65): at the end of surgery, 0.3 mg/5 ml scopolamine (scopolamine group), 4 mg/5 ml ondansetron (ondansetron group), 0.3 mg scopolamine plus 4 mg ondansetron per 5 ml (combination group), or 0.9% normal saline 5 ml (control group) were intravenously infused, respectively. The episodes of PONV and adverse effects were observed within 24 hours after operation.

RESULTSThe incidences of PONV within 24 hours after surgery were 87.7%, 89.2%, and 92.3%, respectively, in scopolamine group, ondansetron group, and combination group, which were all significantly higher than that in control group (73.8%) (all P < 0.05). However, the incidences of PONV showed no significant difference among these three groups (P > 0.05). No significant difference in the incidence of adverse effects was observed among the four groups (P > 0.05).

CONCLUSIONIntravenous scopolamine (0.3 mg), with a comparable efficacy as ondansetron 4 mg, can effectively decrease the incidence of PONV after CS.
