Background and purpose:Although FDG tumor imaging has been applied in clinic widely, dual-phase imaging can provide much more information about the FDG uptaking of pulmonary lesions. The purpose of the study was to evaluate the usefulness of dual-phase18F-FDG coincidence detection SPECT/CT imaging in the differential diagnosis of the pulmonary lesions.Methods:There were 28 patients with pulmonary lesions which were detected by CT. All the patients undertook the SPECT/CT imaging at 2 time-phases respectively: early imaging at 40-60 min and delayed imaging at 2-3 h after the intravenous injection of FDG. Data processing: calculating the radio of T and N in early and delayed imaging respectively; T: The radioactive count of the lesions; N: The radioactive count of the normal tissue; and the change rate:ΔT/N. ROC was used to ifnd out the threshold of T1/N1, T2/N2及ΔT/N in the differential diagnosis between benign and malignant lesions. AUC was used to evaluate the diagnosis value of the dual-phase and single-phase imaging.Results:The threshold of T1/N1 in early imaging was 2.65, whereas AUC was 0.767. The sensitivity, speciifcity and accuracy were 83.3%, 30% and 64.3%, respectively. The threshold of T2/N2 in delayed imaging was 3.14, whereas AUC was 0.847. The sensitivity, speciifcity and accuracy were 94.4%, 60.0% and 82.1%, respectively. The threshold ofΔT/N in delayed imaging was 16.9%, whereas AUC is 0.950. The sensitivity, speciifcity and accuracy were 88.5%, 71.4% and 86.2%, respectively.Conclusion:Dual-phase18F-FDG coincidence detection SPECT/CT imaging has much higher accuracy and speciifcity. However it still has false positivity, and should be analyzed with CT and clinical history.

Objective To explore the clinical curative effect of hollow screw internal fixation for the treatment of distal epiphyseal teenagers tibial fracture.Methods Thirty -nine cases of epiphyseal fractures of the distal tibia were treated in Shanghai Children′s Hospital between February 2005 and September 201 4.This study included 24 boys and 1 5 girls with the average age of 1 3.1 years (ranged 1 0.5 to 1 6.2 years old).Preoperative diagnosis was confirmed by the X -ray films or CT examination.All the cases were closed fractures and manipulative reduction all failed.Surgi-cal reduction was performed when plain radiographs showed the fracture gap of epiphysis board and articular surface were greater than 2 mm or after closed reduction.Under C -arm X -ray machine,ankle axial traction was performed initially.Anatomical reduction underwent according to the bone fracture type.The fractures were fixed with cannulated screws by percutaneous or open approach.Postoperative X -ray or CT confirmed anatomical reduction at articular sur-face and growth plate.All patients had been immobilized with short -leg cast for 4 -6 weeks.The ankle joint function and growth were evaluated by means of American Orthopaedic Foot and Ankle Society(AOFAS)Ankle Hindfoot Scale. Results All patients were followed up for 5 to 91 months with an average duration of 35 months.X -ray films showed that all fractures were bone healing.No uneven articular surface was found and there was no extremity rotation and shorte-ning deformity.Results were evaluated by AOFAS scoring system:excellent in 27 cases,good in 10 cases,and general in 2 cases.All patients were able to participate in the normal physical activities.Conclusions CT with multiplanar recon-struction is a premise to make an accurate diagnosis and to choose a reasonable approach.For failed closed reduction for adolescent distal tibial epiphyseal fractures,the cannulated screws are simple and may have a satisfactory effect.

Objective To study the role of water exact from salvia miltiorrhiza (SM) in promoting hair regrowth in testosterone (T)-induced alopecia in mice.Methods Pathological alopecia mice were induced by T and the mice were randomly divided into control group,model group,Zhanggvanp 101 group,SM low-dose group,SM middle-dose group,SM high-dose group (20,40,80 mg/ml,respectively).The effects of SM on hair regrowth were evaluated by measuring hair length,weight and the number of hair follicle.The concentration of serum T and estrodiol (E2),the content of skin VEGF,MDA,SOD,and GSH-Px were measured after external inunctum for 21 days.Results (1) SM significantly promoted regrowth hair length,weight and the number of hair follicle (P＜0.05) (2) SM significantly balanced the hormones by reducing levels of T and increasing E2 (P＜0.05) (3) SM significantly reduced the content of MDA by increasing the activity of SOD and GSH-Px (P＜0.05) (4) SM significantly increased the level of VEGF (P＜0.05) Conclusion In the pathological alopecia mice induced by T,SM can effectively promote the hair regrowth,with the possible mechanism of balancing hormones,being anti-oxidant and improving VEGF expression.

Objective To determine the relationship between stressors and mental health among postgraduates in military medical universities. Methods This article analyzed population variable, mental health, the correlation of personality, coping styles and pressure based on Military Academy Graduate Student Stress Scale, Symptom Checklist-90, Simplified Coping Style Questionnaire and Eysenck Personality Questionnaire. Independent sample t-test and single factor analysis variance were used to compare the feel-ing of pressure differences among demographic variables groups and mental health differences between high and low pressure group. Pearson product-moment correlation and multiple step-wise regression analysis were performed to explore the relationship of personality, coping styles and feeling of pressure. Results ①There was significant difference on stressors among postgraduates in military medical universities (F=77.397, P=0.000), and LSD test showed that academic pressure> distribution pressure>economic pressure>marriage pressure>family pressure (P<0.05). ②Except phobic factors, SCL-90 total score and each dimension points of high stress group were significantly higher than that of low stress group (P<0.05).③Negative coping style and EPQ multiple dimensions significantly related to feeling of pressure values in post-graduate students. Neuroticism, lie and extroversion entered the regression equation (F=16.959,P=0.001) and together explained 19.0% of the total variance. Conclusion The pressure from teachers, academic, graduation distribution and application for jobs are the main source of pressure. And the students with high pressure sensitivity get poor mental health and tend to have neurotic personality traits and negative coping styles.

Objective To explore the effects of baicalin in the treatment of a preeclampsia (PE) rat model by detecting the expression of X-linked inhibitor of apoptosis protein (XIAP) and cysteine containing aspartate-9 (Caspase-9) and observing the ultrastructure of mitochondria in trophoblast cells.Methods Forty-eight pregnant Wistar rats were randomly divided into two groups:12 in the control group and 36 in the PE model group.The PE model was established with subcutaneous injection of l-nitro arginine methyl ester with 100 mg/kg per day from the 13th day of pregnancy.Beginning from the 16th day of pregnancy,the PE rats were injected with different doses of baicalin till cesarean section,and divided into three groups:non-intervention PE model group treated with saline (NIP group),low-dose baicalin intervention group (IDB group) at 50 mg/kg per day,and high-dose baicalin intervention group (HDB group) at 100 mg/kg per day.The rat tail artery blood pressure and 24-h urine protein level were measured at pregnant day 10,16 and 20.The levels of XIAP and Caspase-9 in placenta were measured by immunohistochemistry.The ultrastructure of mitochondria of trophoblast cells of the rat placenta was observed under electron microscope.T test,F test and LSD-t test were applied for statistical analysis.Results (1) On pregnant day 10,no significant differences were observed in rat tail artery systolic blood pressure,diastolic blood pressure and 24-h urine protein level between the control group and PE model group (all P＞0.05).On pregnant day 16 and 20,the systolic blood pressure,diastolic blood pressure and 24-h urine protein level of NIP,IDB and HDB groups were significantly higher than those of control group [pregnant day 16:systolic blood pressure:(137.74±5.21),(136.15±4.86),(138.28±4.79) and (110.57±3.79) mmHg (1 mmHg=0.133 kPa),diastolic blood pressure:(89.58 ± 5.50),(88.45 ± 8.59),(89.42 ± 6.29) and (80.28 ± 7.36) mmHg,24-h urine protein:(7.78 ± 0.45),(7.53 ± 0.54),(7.86± 0.57) and (6.45 ± 0.56) mg;pregnant day 20:systolic blood pressure:(145.26 ± 4.67),(131.28 ± 4.34),(130.93 ± 5.33) and (110.40 ± 6.92) mmHg,diastolic blood pressure:(89.87±6.55),(85.34±7.33),(84.64±7.36) and (80.19±7.34) mmHg,24-h urine protein:(11.18±0.42),(9.65±0.54),(9.06±0.56) and (6.31 ±0.45) mg] (all P＜0.01).On pregnant day 20,the systolic and diastolic blood pressure and 24-h urine protein level in IDB and HDB groups were significantly lower than in NIP group (all P＜0.05),but showed no significant differences between IDB and HDB groups (allP＞0.05).(2) Compared with NIP group,the expression of XIAP in control group,IDB and HDB groups were significantly increased(210.39±0.78,180.56±0.82,195.36±0.96 and 192.84± 1.06,all P＜0.01).There was no significant difference in the expression of XIAP between IDB and HDB groups (P=0.66).The expression of Caspase-9 in control group,IDB and HDB groups were significantly decreased compared with NIP group (210.36±0.55,195.53±0.96,198.42± 1.01 and 185.25±0.64,all P＜0.01).There was no significant difference in the expression of Caspase-9 between IDB and HDB groups (P=0.65).Ultrastructure of mitochondria in NIP group showed different degrees of damage,matrix swelling,and mitochondrial cristae bresk or disappearance.In IDB group,mitochondrial matrix swelling was not obvious,and mitochondrial cristae were visible.In HDB group,mitochondrial cristae were neat and clear.Conclusions Baicalin may play an important role in the treatment of preeclampsia by reversing the trophoblast apoptosis and improving the ultrastructure of mitochondria through its regulation of XIAP expression and downregulation of Caspase-9 expression.
