Objective To investigate the distribution of eosinphililic neurons ( ENs),reactive astrocytes ( RAs),and infarction after transient cerebal ischemia,and the time profile of pathomorphological changes.Methods Unilateral forebrain ischemia was induced in Mongolian gerbils by two 10 minutes unilateral common carotid artery occlusions with a 5 hours interval.Laser Doppler flowmetry was used to detect intra-ischemic anterior cortex blood flow.Animals were sacrificed at 24 hours,4 days,2 weeks,4 weeks,16 weeks and the brain were prepared for pathomorphological assay.Results Intra-ischemic laser Doppler flowmetry show significant ischemia during carotid artery occlusion:22.1％ ± 9.5％,26.3％ ± 4.9％,37.5％ ± 3.5％,F =67.219,P ＜ 0.01 ; the decrease was significantly greater in the anterior cortex.ENs appeared in middle and deep layers at 24 hours postischemia,and ENs area extend to all layers of cortex by 4 days.Large areas of high EN density ( ≥80/mm2) evolved to infarcts between 4 days and 4 weeks.Posterior cortex evolved to low EN area ( ＜ 80/mm2) without transformation into infarcts.RAs were consistently distributed in areas with ENs,and RA areas with high EN density were largely transformed into infarcts between 4 days and 4 weeks. Delayed astrocytic death took place in the RA areas with high EN density.Conclusion Density of ENs is an important indicator of delayed astrocytic death and infarction in postischemic tissue.

Experimental course of pathology is a very important part of pathology teaching.Motivation of students was promoted through improving the professional knowledge of teachers,using teacher-student interacted teaching methods,increasing network courscs,using multimedia in teaching and adding extracurricular practice in our university.In the meantime,it was successful and fruitful to use diversified evaluation systems to assess the comprehensive experimental capacity of students,which can provide experiences in reform of pathological experimental teaching.

Objective To analyze and compare the differences in application of 24-hour dietary recall and dietary balance index (DBI) in dietary survey and evaluation of patients with type 2 diabetes mellitus,meanwhile investigate their nutrition status.Method This was a cross-sectional study.A total of 100 type 2 diabetes inpatients at the age of 19-59 were recruited from Shanghai Jiaotong University Affiliated Sixth People's Hospital from December 2013 to February 2014.They were surveyed and evaluated by 24-hour dietary recall and DBI respectively.Result The micronutrient intake in patients with type 2 diabetes was not sufficient.Compared with RNI,the intake of vitamin B1,B2,and calcium was less than 50％.The average of DBI lower bound score (DBI-LBS) of the 100 patients was 32.1±6.1,65％; the patients were in moderate or severe deficit of food intake.DBI higher bound score (DBI-HBS) was 4.4±2.8.No significant excess intake problem was found.Dietary quality distance was 36.4±6.9.Eighty-seven percent of them had a dietary patterns of mode B.Conclusion Dietary patterns in type 2 diabetes patients were not reasonable.Nutrition education and nutrition intervention for type 2 diabetes should be emphasized.The two methods can be used to evaluate dietary quality independently,but it would be better to evaluate the quality of the patients' diet using two dietary survey methods together.

Objective To evaluate the role of (99)Tc(m)-MDP SPECT/CT bone fusion imaging in diagnosis and treatment strategy establishment of patients with bone metastatic malignancy.Methods Retrospective study was carried out on 66 patients (55 patients with primary malignant tumors,11 patients with primary benign bone disease) chosen from 117 patients who had undergone whole body bone scintigraphy and SPECT/CT fusion imaging examination.Comparison was carried out on diagnostic efficacy for bone metastases and changes of treatment between SPECT/CT fusion imaging and other anatomical imaging (CT and/or MR).Cases excluded are extensive bone metastases and no final diagnosis of patients.Results For diagnosis of patient with bone metastasis and bone metastasis lesion,the sensitivity of SPECT/CT fusion imaging was (90.62％,93.88％),specificity (79.41％,89.47％) and accuracy (84.84％,90.97％),while sensitivity of simple anatomical imaging was (59.38％,51.02％),specificity (94.11％,94.73％) and accuracy (77.27％,79.86％),with a significant difference (P ＜ 0.05).SPECT/CT fusion imaging changed 30.31％ (20/66) the patient's treatment plan,while 16.67％ (11/66) for simple anatomical imaging,with a significant difference (P ＜ 0.05).Conclusions SPECT/CT fusion imaging could increase the accuracy of diagnosis of bone metastases and have an important role in establishing the treatment strategy.

OBJECTIVE To investigate theradiosensitization of combined inhibition of signal transducer and activator of transcription 3(STAT3) and hypoxia-inducible factor-1α(HIF-1α)on laryngeal squamous carcinoma of xenograft mice and its underlying mechanisms.METHODS Xenograft mice were divided into 5 groups randomly: control group(A), irradiation group(B), irradiation and AG490 group(C), irradiation and PX478 group(D), irradiation combined AG490 and PX478 group(E). The size of xenograft tumor was measured and calculated. The expression of Ki67 and HIF-1α was detected by immunohistochemical method. Western blot was used to detect the expression of PARP1.RESULTS The size of xenograft tumor in group E was smaller compared with that in group C and group D. There were significantly difference between them respectively (t=12.367,11.598,P=0.000). The expression of HIF-1α in group E was lower than that in group C and group D respectively, and there were significantly difference respectively(t=5.422, 3.000,P<0.05). Ki67 index in group E was lower compared with that in group C and group D respectively and there were significantly difference respectively (t=4.479, 4.352,P<0.05). The level of cleaved PARP-1 in group E was higher than that in group C and group D respectively and there were significantly difference respectively (t=5.507, 7.102,P<0.05). CONCLUSION Combined inhibition of STAT3 and HIF-1α can increase the radiosensitivity of human laryngeal squamous carcinoma in the xenograft mice.

Objective To discuss the clinical application of reverse dorsal metatarsal artery perforator flap for reconstruction of forefoot soft tissue defects.Methods Since January,2008 to March,2016,43 patients with forefoot soft tissue defect due to various causes were reconstructed with the flap based on dorsal metatarsal artery perforator.Dorsal pedis was used as a donor site with dorsal metatarsal artery perforator as the donor artery.The flap size varied from 2.0 cm × 4.0 cm to 6.0 cm × 8.0 cm.Among them,27,8,4 and 4 cases were reconstructed with flap based on first,second,third and fourth dorsal metatarsal artery perforator flap respectively.Results All the patients were followed-up which ranged from 3 months to 24 months.Six flaps suffered from post operative venous congestion.Out of 6,4 survived with early emergency management while the remaining 2 suffered epidermal necrosis which survived with regular dressing change.Eventually,all the flaps survived.They had good texture and they were elastic,good-looking and very wear-resisting.Walking function was normal.Conclusion Reverse dorsal metatarsal artery perforator flap is an ideal choice in reconstruction of small to medium sized soft tissue defects of forefoot.
