Objective To develop an early diagnosis strategy for radiation-associated breast angiosarcoma after breast cancer radiotherapy (RABASBCR) and to avoid the misdiagnosis of this disease.Methods A systematic search of PubMed for published reports of RABASBCR cases was performed.The clinical manifestations and radiological features in the early stage of disease,as well as biopsies,were analyzed to screen out valuable markers for early diagnosis and develop the early diagnosis strategy for RABASBCR.Results Fifty-five original articles involving 80 RABASBCR patients were selected for this analysis.Twenty-four (30％) of the 80 patients were misdiagnosed;the median time of misdiagnosis was 3 months (1-24 months).The earliest symptom was skin changes in 76 (95％) of the 80 patients.The misdiagnosis rates of ultrasound,mammography,computed tomography,and magnetic resonance imaging for RABASBCR were 9/9,31/32,2/2,and 1/5,respectively.The misdiagnosis rates of fine needle biopsy,core needle biopsy,and incisional biopsy were 7/14,12/25,and 10/26,respectively.Conclusions By analyzing published case reports,we have set up the early diagnosis strategy for RABASBCR with reference to the Cahan criteria.

Thirty nine compounds in the volatile oils of the flowerbuds of Panax quinquefolium L.cultivated in China were isolated and identified with gas chromatography/mass spectre metry. To our great surprise,β-famensene,a sesquiterpene compound of them,alone account for 48.67% of the total volatile oils contents. This experimental result was contrasted with the volatile oils components of the different parts of Panax quinquefolium L.and Panax ginseng,anidentical genus plant,on chemical components and relative quantities.It was discovered that the only one common component is β-famensene in them and it is the highest value in determined relative contents. Above result provides scientific basis for biological synthesis of triterpenoid saponins.

Objective To analyze the clinic characteristics, lifetime and prognostic factors of young female breast cancer patients. MethodsClinical data of 155 patients under 35 years of age with breast cancer were retrospectively reviewed and followed up.ResultsThe positive rate of hormone receptors was 61.6 % (77/125) in all cases who had been detected receptor status. The median survival time in hormone receptors positive and negative group were 119.0 and 51.3 months (P＜0.01), and 5-year survival rates were 68 % and 33 %, respectively. For patients who had been treated with adjuvant tamoxifen (47.1%), the median survival time was 182 months which longer than without tamoxifen (P ＜0.05). The median disease-free survival time and median survival time were 24 and 91 months in all cases. The overall 3-, 5- and 10-year survival rates were 79 %, 60 % and 51%, respectively. Multifactor analysis with the COX model indicated that tumor size, axillary metastatic status, tamoxifen treatment and overexpression of Her-2 were independent prognostic factors. While clinic stage and hormone receptors status might be referenced prognostic factors. ConclusionYoung women breast cancer patient may have good prognosis if multimodality treatment is conducted. Tumor size, axillary metastatic status, adjuvant endocrine therapy and overexpression of Her-2 are independent prognostic factors.

Objective To investigate the relationship of homocysteine and blood glucose wavy coefficient with type 2 diabetic nephropathy.Methods Glycosylated hemoglobin A1c (HbA1c),fasting blood glucose(FBG),fasting C-peptide,homocysteine(Hcy),blood-fat and 24h urinary albumin quantitative (UAlb) of 154 patients with type 2 diabetes were determined,and the blood glucose wavy coefficient were calculated after blood glucose monitored by a continuous glucose monitoring system (CGMS).The patients were divided into two groups according to the quantity of UAlb:high UAlb group (n =81 ) and normal UAlb group( n =73 ).Then the difference were compared between two groups and multiple regression analysis was done between UAlb and a variety factors.Results The course of disease in high UAlb group were significantly longer than that in normal UAlb group ( (9.68 ± 7.31 ) years vs ( 5.44 ± 3.65 ) years,t =3.427,P ＜ 0.05 ).There were significant difference on HbA1c [ ( 9.61 ± 2.44 ) ％ vs ( 8.69 ± 2.35 ) ％,t =2.162 ],blood glucose wavy coefficient [ ( 3.06 ± 0.85 ) vs (2.58 ± 0.91 ),t =2.437],low density lipoprotein-cholesterol (LDL-C) [ (3.46 ± 0.83 )mmol/L vs ( 3.01 ± 0.84 ) mmol/L,t =2.596 ],UAlb [ ( 129.64 ± 118.5 ) mg/24 h vs ( 18.14 ± 3.54 )mg/24 h,t =6.421 ),UA ( ( 335.02 ± 90.39 ) mmol/L vs ( 287.00 ± 92.03 ) mmol/L,t =2.541 ) and Hcy [ ( 15.55 ± 4.53 ) mmol/L vs ( 13.12 ± 4.44 ) mmol/L,t =2.603 ] between the two groups ( P ＜ 0.05 or P ＜0.01 ).Pearson analysis showed that the courses of disease,LDL-C,UA,Hcy and blood glucose wavy coefficient were positively correlated with UAlb ( r =0.363,0.270,0.220,0.252,0.236 respectively ; P =0.000,0.008,0.033,0.014,0.022,respectively).And the multiple regression analysis indicated that UAlb was related with courses of disease(β =0.344,P =0.000),Hcy(β =0.244,P =0.011 ) and blood glucose wavy coefficient(β =0.229,P =0.012).Conclusion The elevation of serum Hcy and blood glucose wavy coefficient are risk factors to type 2 diabetic nephropathy.Lowering Hcy concentration and reducing the glucose variability may be a new way to prevent the occurrence of type 2 diabetic nephropathy.

Objective To investigate the relationship and mechanism of the heme oxygenase-1 expression in peripheral blood mononuclear cells (PBMC) and the oxidative stress in diabetic nephropathy. Methods Two groups of diabetic patients with or without diabetic nephropathy and a normal control group were enrolled in this study. Fasting blood glucose (FBG), HbA1c, serum MDA level, ROS level, HO-1 mRNA level and HO-1 protein expression in PBMC were determined. Results In control group, diabetic group and diabetic nephropathy group , the MDA levels significantly increased[(14.23±5.07)nmol/ml vs (24.90±7.12)nmol/ml vs (43.83±16.97)nmol/ml](F＝37.022,P＜0.01), the ROS levels significantly increased (113.18±58.59 vs 364.54±88.67 vs 524.35±162.51)(F＝68.369,P＜0.01) and the HO-1 protein expression also increased significantly (22.84±9.98 vs 36.72±15.85 vs 58.1±15.93)(F＝31.302,P＜0.01). There was a positive correlation among the HO-1 mRNA, protein expression and MDA level(r＝0.407,0.429,P＜0.05). Conclusions There existed a severer oxidative stress condition in patients with diabetic nephropathy compared with the patients without diabetic nephropathy. HO-1 could be a potential pathway to ameliorate oxidative stress in diabetic kidney disease patients.

Aim By establishing mouse acute myocardial infarction model,to observe the protection of isoflavones on ischemic myocardium and research the mechanism.Methods Mouse acute myocardial infarction model was established by ligating the left anterior descending(LAD)coronary artery.Danshen was used as the positive control.The effect of isoflavones on myocardial infarct area,serum myocardium creatase and serum levels of SOD and MDA was observed.By Real Time PCR,it was found that isoflavones could affect the expression of β-adrenergic receptor kinase(β-ARK_1).Results Isflovones could obviously reduce the myocardial infarct area and lower the levels of serum myocardial creatase and MDA.It could downregulate the expression of β-ARK_1 as the doses are increased.Conclusions Isoflavones can protect the myocardium of acute myocardial infarction mouse.The mechanism is related to the reduction of the oxidative damage,and the downregulation of the expression of β-ARK_1.

Objective:To study the pathogenic distribution of bronchoalveolar lavage fluid in children with severe pneumonia from Children′s Hospital Affiliated to Soochow University, and to investigate the drug resistance of major pathogenic bacteria.Methods:A total of 177 children with severe pneumonia undergoing fiberoptic bronchoscopy in Children′s Hospital Affiliated to Soochow University from January 2014 to December 2018 were enrolled.Their bronchoalveolar lavage fluid was collected for pathogen identification, pathogen culture and drug sensitivity analysis.The pathogens were detected by direct immunofluorescence quantitative PCR.Results:Of 177 cases enrolled, 100 children had at least one pathogen detected, and the positive rate was 58.13%.Among all the pathogens detected, Mycoplasma pneumonia (MP) had the highest detection rate, which was found in 41 cases.The top three bacteria detected included Streptococcus pneumoniae (9 cases, 10.59%), Staphylococcus aureus (8 cases, 9.41%), and Pseudomonas aeruginosa (6 cases, 7.06%). The top three viruses detected were cytomegalo virus (CMV) (14 cases, 33.33%), human bocavirus (HBoV) (10 cases, 23.81%), and respiratory syncytial virus (RSV) (8 cases, 19.05%). The drug sensitive test indicated that main kinds of Gram-negative bacteria had low resistance to quinolones, aminoglycosides, carbapenems, and enzymatic beta-lactams.Main kinds of Gram-positive bacteria had low resistance to Linezolid and vancomycin.The virus detection rate and MP detection rate in severe pneumonia children under 5 years old were about 30.00% and 20.00%, respectively.The MP detection rate in children above 5 years old exceeded 30.00%.The bacteria detection rates in children under and above 2 years old were over 20.00% and about 15.00%, respectively.Airway abnormalities were common in children with severe pneumonia, mainly including tracheobronchial malacia and stenosis. Conclusions:The most common pathogen of bronchoalveolar lavage fluid in severe pneumonia children under 5 years old in Suzhou is viruses.The bacteria detection rate is high in children under 2 years old.Common Gram-positive bacteria show high susceptibility to vancomycin and Linezolid. Pseudomonas aeruginosa is highly sensitive to quinolones, aminoglycosides, carbapenems, and enzymatic beta-lactams.Importance should be attached to the airway abnormalities in children, especially infants, with severe pneumonia.
