Professor Y ang Y ufe i is the director and founder of the Oncology Department of X iyuan Hospital of China Academy of Chinese Medical Sciences. Professor Y ang Y ufei thinks highly of the treatment of breast cancer with harmonizing and dredging principle combining traditional Chinese medicine (TCM) and western medicine. She regards the basic pathogenesis of breast cancer is not only on traditional liver-kidney yin deficiency and liver-qi stagnation with spleen deficiency, but also three mechanisms which are breakdown of the normal physiological coordination be-tween the liver and kidney, heart and the kidney and Shaoyang. Professor Y ang gradually formed Tri-Traffic Dredg-ing Liver And Nourishing Kidney Formula base on tonification and purgation in combination. Y ang Y ufei thinks highly of combining treatment of TCM and western medicine, especially combined with endocrine therapy. Professor Y ang also pays much attention on immune function of patients and health education.

Objective To study the clinicopathologic features,immunophenotype,diagnosis and differential diagnosis of solid papillary carcinoma (SPC) of breast.Methods A retrospective study was performed to analyse the clinicopathologic features and immunophenotype of 31 cases of SPC with or without invasion.The cytokeratins (CK),myoepithelial markers,neuroendocrine markers,proliferation marker Ki-67,estrogen receptor (ER),progesterone receptor (PR),HER2,ect were detected by immunohistochemical staining,and HER2 was detected by FISH.All patients were followed up.Results All the patients were females with a mean age of (67.0±12.5) years.The presenting symptom was a painless mass with or without nipple discharge.In 19 cases who had undergone axillar lymph node dissection,only one metastasis was observed.General observation showed that tumors had substantive and nodular lesions,accompanied by cyst formation.Microscopy examination showed that tumors had swell and substantive nodules with only fine fiber vascular axis,and lacked obvious nipples and screen structure.The cells were lack of atypia,adhesive in cells nest.20 patients were accompanied by mucus secretion.Immunohistochemical study showed that the tumor cells expressed CK8/18,ER,PR,but didn' t express basal cell CK5/6,34β12.The positive rates of CK5/6,34β12,p63 were 3.23 ％ (1/31),9.68 ％ (3/31),6.45 ％ (2/31) in the myoepithelial layers of axis of papillary,and were 19.25 ％ (6/31),38.71％ (12/31),16.13 ％ (5/31) in peripheral cell nests and tumors,respectively.The positive rates of CgA,Syn,NSE,Cd56 were 83.87 ％ (26/31),87.10 ％ (27/31),93.55 ％ (29/31),90.32 ％ (28/31),respectively.The staining of HER2 oncoprotein was negative mostly,and the FISH detection outcome of 15 cases were all negative.The average positive index of Ki-67 was 4.12 ％.28 cases (90.23 ％) received follow-up,only 1 patient died,and the rest patients were without tumor recurrence or metastasis.Conclusions SPC of breast,a rare pathologic type,usually occurs in old females.The diagnosis depends on pathological characteristics and its unique immune phenotypic characteristics.SPC of breast has close relationship with mucinous carcinoma and neuroendocrine carcinoma,with a relatively inert biological behavior.

Objective To study the clinicopathologic features,immunophenotype,diagnosis and differential diagnosis,prognosis and treatment of solid papillary carcinoma(SPC)of breast.Methods A retrospective study was performed to analyse the clinicalpathologic features and immunophenotype of 52 case of SPC,with or without invasion. The cytokeratins(CK),myoepithelial markers,neuroendocrine markers,proliferation marker Ki -67,estrogen receptor (ER),progesterone receptor(PR),HER2,ect were detected by immunohistochemical staining,and HER2 was detected by FISH.All patients were followed up.Results All the patients were females with a mean age of (66.76 ±10.19)years. The incidence of SPC among all the breast cancers in this department was 0.99%.The presenting symptoms was a painless mass with or without nipple discharge in the central of breast.All of them accepted surgical resection,13 cases were administrated with chemotherapy after surgery,6 cases were radiotherapy.Metastasis was observed four in 34 cases who had undergone axillar lymph node dissection.General observation tumor was substantive and nodular lesions,may be accompanied by cyst formation,microscopy tumor for swelling,substantive nodules within only fine fiber vascular axis,and lacked obvious nipples and screen structure.The cells were lack of atypia,adhesive in cells nest,35 patients were accompanied with mucus secretion.Immunohistochemical study show that the tumor cells experssed CK8 /18,ER and PR,but not basal cell cytokertin CK5 /6 and 34βE12.Positivity for CK5 /6,34βE12 and P63 were 5.78%, 9.62% and 7.69% in the myoepithelial layers of axis of papillary,and were 21.15%,38.46% and 19.23% in cell nests and tumor peripheral myoepithelial,respectively.Positivity for CgA,Syn,NSE,CD56 were 82.69%,88.46%, 94.23% and 90.38%,respectively.The staining of HER2 oncoprotein was most negative,and 23 cases of FISH detection were all negative.The average positive index of Ki -67 was 4.28%.47 cases received follow -up of patients(90.38%),only 1 case death,1 case recurrence the rest were no tumor recurrence or metastasis,disease -free survival.Conclusion SPC of breast,a rare pathologic type,usually occurs in old females.The diagnosis depends on pathological characteristics and its unique immune phenotypic characteristics,is closely associated with mucinous carcinoma and neuroendocrine carcinoma,and the treatment is given priority tosurgery with a relatively inert biological behaviour.

This study was aimed to evaluate the relationship between the changes of plasma intermedin (IMD) and atrial fibrosis in hypertensive patients with atrial fibrillation. During the period from 2010 to 2011, appropriate 150 subjects of out-patients (female 50%, male 50%) were selected in West China Hospital, Sichuan University, and were divided into three groups: the hypertension-only group, the hypertension combined with paroxysmal atrial fibrillation group and the hypertension combined with persistent atrial fibrillation group. Firstly, we collected the Physical examination results and medical history records of the patients. We then performed ultrasound cardiogram and blood biochemical tests on the patients. We also detected the plasma IMD and transforming growth factor β1 (TGF-β1) using ELISA. The results showed that compared with the hypertensive group, the plasma level of IMD, TGF-β1 and left atrium director (LAD) in the hypertensive combined with atrial fibrillation group were higher significantly. Compared with the paroxymal atrial fibrillation group, the levels of IMD, TGF-β1 and LAD were higher significantly in persistent atrial fibrillation group. Analysis of correlation and partial correlation showed that IMD was positively correlated with TGF-p1 (r=0.51, P<0. 001), IMD was positively correlated with LAD(r=0.59, P< 0.001), and TGF-β1 was positively correlated with LAD (r = 0.57, P < 0.001). The results suggest that IMD might suppress the pathophysiological process of atrial fibrillation.

[ ABSTRACT] AIM:To investigate the changes of migration of lung adenocarcinoma cells promoted by IL-8 and the inner and outer mitochondrial membrane dynamic changes during this process.METHODS:Human lung adenocarci-noma cell line A549 was divided into control group and IL-8 group.Cell migration was analyzed by scratch detection and Transwell assay.The secretion of endogenous IL-8 was detected by ELISA.The protein levels of mitochondrial cytochrome C ( Cyt C) and mitochondrial outer membrane protein Tom20 was detected by Western blot.The mRNA expression of mito-chondrial fusion genes Mfn1, Mfn2 and OPA1 and fission genes Fis1, Drp1 and MTP18 was detected by RT-PCR.The morphological changes of mitochondria were observed by MitoTracker Red CMXRos dye staining and confocal microscopy. RESULTS:The migratory rate of A549 cells and endogenous secretion of IL-8 in A549 cells were higher than those in SPC-A-1 cells.The migratory rate of A549 cells was improved by IL-8 in a time-dependent manner.Compared with control group, the Tom20 protein expression was increased ( P<0.05 ) , and the Cyt C protein expression was decreased ( P<0.05).The expression of mitochondrial outer membrane fusion genes Mfn1 and Mfn2 was increased (P<0.05), and the expression of mitochondrial inner membrane fusion gene OPA1 was decreased (P<0.05).The expression of fission genes Drp1 and MTP18 were decreased (P<0.05), while the expression of Fis1 was no change (P>0.05).Under confocal microscope, the punctate aggregates in the mitochondria of the A549 cells treated with IL-8 were observed.CONCLU-SION:The migratory rate of A549 cells is increased by IL-8, which is related to the changes of mitochondrial fusion genes and the fission genes.

Establishment of quality management system (QMS) plays a critical role in the clinical data management (CDM). The objectives of CDM are to ensure the quality and integrity of the trial data. Thus, every stage or element that may impact the quality outcomes of clinical studies should be in the controlled manner, which is referred to the full life cycle of CDM associated with the data collection, handling and statistical analysis of trial data. Based on the QMS, this paper provides consensus on how to develop a compliant clinical data management plan (CDMP). According to the essential requirements of the CDM, the CDMP should encompass each process of data collection, data capture and cleaning, medical coding, data verification and reconciliation, database monitoring and management, external data transmission and integration, data documentation and data quality assurance and so on. Creating and following up data management plan in each designed data management steps, dynamically record systems used, actions taken, parties involved will build and confirm regulated data management processes, standard operational procedures and effective quality metrics in all data management activities. CDMP is one of most important data management documents that is the solid foundation for clinical data quality.

Objective To study the correlation between blood flow parameters by three-dimensional sonography and Nottingham prognostic index (NPI) of breast cancer.Methods A retrospective analysis of sonographic image data of 89 patients who were pathologically confirmed invasive ductal breast cancer was made.The technology of three-dimensional color power angiography (3D-CPA) was used to obtaining vascular index (VI),flow index (FI) and vascular-flow index (VFI) before the operation.NPI was obtained by a formula which was computed on a basis of postoperative pathological data.The case of VI,FI and VFI in different grades and NPI in various prognosis groups were counted,and the relationship between blood flow parameters and NPI was analyzed.Results The correlation coefficient between VI and NPI was 0.643 (P ＜0.0001) and there was no significant correlation between FI,VFI and NPI.Conclusions Among VI and NPI there was a considerable positive correlation,VI was helpful to evaluate the prognosis of patients before operation and to provide basis for clinical treatment programs.

Objective To compare the efficiency and safety of double-channel flexible ureteroscopy and electronic flexible ureteroscopy.Methods From April 2007 to 2016 July, clinical data of 836 cases flexible ureteroscopic holmium laser lithotripsy were collected. All the patients were randomly divided into electronic lfexible ureteroscopy group (n = 427) and double-channel lfexible ureteroscopy group (n = 409), the operation time, success rate of surgery, complications, residual stone rate of the two groups were compared.Results The success rate of surgery was 92.5% and 83.6% of the two groups respectively, the difference was significant (P < 0.05); postoperative systemic inlfammatory response syndrome (SIRS) were occurred in 10 cases and 13 cases respectively, which were cured and the difference was not statistically significant (P > 0.05); the average operation time was (81.1 ± 7.9) min and (95.3 ± 7.6) min respectively, the difference was significant (P < 0.05); The formation of stone street of electronic lfexible ureteroscopy group and double-channel lfexible ureteroscopy group were 17 cases and 25 cases. The residual stone rate of electronic flexible ureteroscopy group and double-channel flexible ureteroscopy group were 6 cases and 8 cases, of them were cleared after extracorporeal shockwave lithotrips (ESWL). There were no difference between the two groups (P > 0.05).Conclusion Both double-channel lfexible ureteroscopy and electronic lfexible ureteroscopy are effective and safe therapeutic modalities. Electronic flexible ureteroscopy is better than double-channel lfexible ureteroscopy in success rate of surgery because of its high deifnition and lfexible operation.

Objective To explore the interaction between polymorphisms of rs17222919 which located in the 5-1ipoxygenase-activating protein(ALOX5AP) gene promoter and environmental risk factors in ischemic stroke(IS).Methods We conducted a case-control study involving a total of 622 cases and 631 unrelated healthy controls which were selected from Henan Han populations,and the environment risk factors were recorded.Genotyping aimed at detecting both genetic and environmental factors in relation to IS was performed by TaqMan-polymerase chain reaction technology while interaction indexes (Υ) were calculated to determine interactions and their role models.Results The rs17222919 TG (189/622,30.4％),GG (18/622,2.9％)genotype frequencies and G (225/1244,18.1％)allele frequencies in IS subjects were significantly lower than those in controls (221/631,35.0％ ; 31/631,4.9％ ; 283/1262,22.4％ ; x2 =4.117,P =0.042 ; x2 =4.457,P =0.035 ; x2 =7.294,P =0.007).Negative interactions between TG + GG genotype and hypertension,diabetes or cigarette smoking in the occurrence of IS (Υ =0.943,0.922,0.830) were observed,whose role models were all super-multiplicative models.Conclusions According to our study,ischemic stroke is the result of the interaction of genetic and environmental factors and G allele of rs17222919 may have weakened the role of environmental factors for hypertension,diabetes and cigarette smoking in IS incidence.
