Objective To investigate the expression and significance of Periostin,VEGF and MMP-9 in breast invasive ductal carcinoma.Methods Immunohistochemistry was employed to detect the expression of Periostin,VEGF and MMP-9 in breast invasive ductal carcinoma and normal breast tissue.Results In breast invasive ductal carcinoma and normal breast tissue,the positive rates of Periostin were 63.8 ％ (37/58) and 0 (x2 =24.272,P =0.000).The figures were 69 ％ (40/58) and 8 ％ (2/25) for the positive rates of VEGF (x2 =25.977,P =0.000),respectively,as well as 70.69 ％ (41/58) and 16.0 ％ (4/25) for the positive rates of MMP-9 (x2 =21.050,P =0.000),respectively.There were significant differences among the groups (P ＜ 0.05).In breast invasive ductal carcinoma,the expression of Periostin was correlated with clinical stage (x2 =4.835,P =0.028),whereas not correlated with age (x2 =1.155,P=0.282),histological grade (x2 =0.05,P =0.972),lymphatic metastasis (x2 =1.660,P =0.198).The expression of VEGF was correlated with clinical stage (x2 =4.230,P =0.040),lymphatic metastasis (x2 =9.667,P =0.002),whereas not correlated with age (x2 =0.506,P =0.477),histological grade (x2 =0.532,P =0.767).The expression of MMP-9 was correlated with clinical stage (x2 =8.456,P =0.004),lymphatic metastasis (x2 =5.494,P =0.019),whereas not correlated with age (x2 =0.153,P =0.695),histological grade (x2 =0.224,P =0.894).The expression of Periostin,VEGF and MMP-9 were positively correlated with each other in breast invasive ductal carcinoma (r =0.348,P =0.001; r =0.303,P =0.021; r =0.469,P =0.000).Conclusion Periostin,VEGF and MMP-9 are correlated closely with the occurrence and development of breast invasive ductal carcinoma,which might be valuable in evaluating the invasiveness,metastasis and prognosis.

Objective To explore the clinical characteristics and the cause of misdiagnosis of child suffering from cerebral parago-nimiasis with intracranial hemorrhage as initial symptom,and to improve the diagnosis and treatment level of cerebral paragonimiasis.Methods The clinical data of the children who suffered from cerebral paragonimiasis with intracranial hemorrhage as initial symptom were collected from January 2011 to December 2015 in Affiliated Hospital of Zunyi Medical College.The clinical manifestation,imageology and laboratory tests,outcome of therapy were analyzed and then the effect of treatment and the prognosis were followed up.Results There were 7 patients meeting the inclusion criteria for cerebral paragonimiasis,including 4 male and 3 female.They were from 6 to 13 years old with the average age of 9.3 years old.All patients presented with headache and vomiting,and showed intracranial hemorrhage through CT or MRI of brain.All of the 7 patients were misdiagnosed as cerebrovascular malformation by the neurosurgeons.Three of them showed typical imaging pattern including tunnel sign and the ring-like shape of cerebral paragonimiasis.Five of these cases were attacked by pulmonary distomiasis at the same time.Six of them had an increasing eosinophil,and the paragonimus antibody was positive.They were treated with Praziquantel.Six patients recovered completely,and 1 patient had the dysfunction of left extremities.Conclusions The childhood cerebral paragonimiasis has strong clinical heterogeneity and diversity in manifestation.Intracranial hemorrhage may be the initial symptom,which should be paid more attention to.Cerebral paragonimiasis can be diagnosed and treated early according to the clinical characteristics,the increase of eosinophil,the typical changes in imageology and the specific antibody test.

Objective To evaluate clinical efficacy on treatment of axillary hyperhidrosis by botulinum toxin type A injection and to introduce a corresponding method evolved from Minor's starch iodine test with MATLAB analysis.Methods Ten patients were involved in the study and evaluated preoperatively by both Hyperhidrosis Disease Severity Scale (HDSS) and Minor's starch iodine test with MATLAB analysis.All cases were treated with botulinum toxin type A injection dosed by 50 U on one side focally and evaluated postoperatively by both above mentioned methods with interval of 1 month and by HDSS only of 6 months.Results The clinical efficiency by the therapy evaluated by HDSS accounted for 100％ and 60％ postoperatively with intervals of 1 month and 6 months respectively.By the Minor's starch iodine test with MATLAB analysis,all patients showed no statistical difference between two matched sides preoperatively (P ＞ 0.05),while postoperatively statistical difference was observed between the treated side and the control (P＜0.05) and also between the treated group and zero control (P＜0.05).Conclusions The clinical efficacy of botulinum toxin type A injection in treatment of axillary hyperhidrosis is highlighted in short term.The evolved Minor's starch iodine test combined with MATLAB analysis serves as an alternative which facilitates operability and objectivity evaluating the therapy outcomes on hyperhidrosis.
