12 patients with inconsistent growth of twins were involved.The acoustic features were analyzed,inclu-ding 2D and Doppler images.The differential diagnosis was verified during follow-up exam in some patients.8 cases were diagnosed with sIUGR by ultrasonography,meanwhile 3 were diagnosed with TTTS.The rest 1 case could not be etiologically diagnosed due to the bad image conditions.We can differentiate the two diseases by evaluating the umbilical cord insertion,the amiotic fluid and the hemodynamics of the other twin.Ultrasonography is helpful in the differential diagnosis for TTTS and sIUGR.

Objective To explore the value of combined determination of serum hepatic fibrosis index for evaluation on the degree of liver fibrosis in patients with chronic hepatitis B(HBV).Methods 275 patients with HBV were selected as chronic hepatitis group,which were divided into the mild chronic hepatitis group(75 cases),chronic moderate hepatitis group (72 cases),chronic severe hepatitis group (65 cases),liver cirrhosis group (63 cases) according to the severity of disease.In addition,50 healthy population were selected as the healthy control group.The four liver fibrosis indicators included serum hyaluronic acid(HA),laminin (LN),collagen type Ⅲ (PC Ⅲ),type IV collagen(IV-C) were determined by chemiluminescence immunoassay and compared among the groups,and the diagnostic results of combined different indicators were compared.Results The indexes of HA,PC Ⅲ,IV-C,LN were significantly higher than those of the healthy control group (t =2.567,2.687,2.811,2.741,all P ＜ 0.01).The hepatic fibrosis indexes were increased by with the severity and duration increased gradually (t =2.665,2.787,2.755,2.811,all P ＜ 0.01).The concentration-time curves area (AUC) of PC Ⅲ,Ⅳ-C,LN,HA were 0.680,0.825,0.716,0.826,respectively.Diagnosis value of three combination indicators in HA + PC Ⅲl + Ⅳ-C was highest.Conclusion The chemiluminescence dynamic detection of four liver fibrosis indicators is a good non-invasive detection method for guiding clinical diagnosis on the degree of liver fibrosis.

Objective To establish a LC-MS analytical method for determination of N,N-dimethylaniline which is genotoxic impurity in quetiapine fumarate.Methods The method was achieved by an Waters ACQUITY UPLC CSHTM PhenylHexyl(2.1 mm× 100 mm,1.7 μm) utilizing a mobile phase of buffer-methanol(900∶ 100) (A)-acetonitrile(B) with gradient elution at the flow rate of 0.4 mL·min-1.The temperature of column was set at 50 ℃;The DIONEX Ultimate 3000 HPLC-AB Science 4000 QTrap Tripling Four bar LC-MS to detect N,N-Dimethylaniline (ESI source,in MRM positive mode).Results Standard curve was linear in the range of 0.4-8.0 ng(r =0.999 3);The limit of detection was 0.2 ng;The limit of quantification of N,N-dimethylaniline was 0.4 ng,respectively.The average recovery of N,N-dimethylaniline was 103.3 ％;RSD was 4.3％ (n =9),respectively.Conclusion The method is convenient and sensitive for the determination of N,N-dimethylaniline in quetiapine fumarate.

Objective To detect a quantitative relation between reaction time of substance P (SP) and histamine release of mast cells (MC) in hypertrophic scar (HS) and discuss the interaction and time-effect of substance P and histamine release in HS. Methods The HS specimens were from the 4 to 7-year-old scalded or burnt patients who underwent operation because of cicatricial contraction. The normal skins were the autograft. HS specimens were cut into 0.5-1 mm 3, then treated with 5?10 -5 mol/L SP for 5, 15, 30, 60 min. The degranulation of MC was detected and the histamine released by mast cells in the supernate after SP treatment was examined by immunofluorescence. Conclusion SP and MC are of a close relationship in HS, and SP can affect histamine release of mast cell in time-dependent manner.

It is the most important mission that preserving and developing advancement of TCM theory and practice.We need defi nitive medical standard to standardize the development.Whether there was any standards in the history of traditional Chinese medicine is a hot question.Though the history research,we found that TCM classic literature was the medical standard in ancient China,which was confirmed by Tang-song government though official action.The standard teaching materials promoted the communication and development of TCM.After Song dynastythe standard position and function was strengthened continuouslywhich had a profound effect.

Objective To analyze the distribution of multiple myeloma (MM) literature in Chinese periodicals and to find out the core periodicals about MM.Methods Periodical literature that involved with MM in the article titles from January 2008 to December 2014 on the Wanfang medical database was collected and searched.Bibliometric method was used to analyze journal date and journal distribution.Results 456categories of periodicals had published literature about MM.The number of articles about MM published in the top 10 journals was more than 30,accounting for 27.00 ％ of all published MM literature,which were highly effective core journals.The number of articles about MM published in the top 3 journals was more than 100,accounting for 15.59 ％ of all published MM literature.The number in Journal of Leukemia & Lymphoma had reached 187,accounting for 6.43 ％ of the total.Conclusions The core journals about MM provide the key approach to help MM medical personnel to select useful information efficiently.Furthermore,the core journals are not only the significant gist for authors who plan to contribute their articles to relevant MM periodicals,but also the necessary reference tools for medicine workers who engage in basic and clinical research and teaching.

Objective: To study the clinical features, image findings, therapeutic strategies, and prognosis of adult and juvenile patients with Takayasu arteritis (TA). Methods: The clinical data of 125 patients with TA were retrospectively studied. Results: There were 108 female and 17 male patients. The mean age of onset was (26.9±11.0) years and 31 patients were younger than 18 years at onset. Constitutional symptoms, pulse deficit, and elevated erythrocyte sedimentation rate (ESR) were present in 38.4%, 71.2%, and 49.6% of patients, respectively. Compared with adult patients, the incidences of constitutional symptoms, pulse deficit and elevated ESR were lower in juveniles(P<0.05). Angiographic findings showed that Type I(40%), Type IV (20.8%) and Type V (30.4%) were common, and Type IIa (4.8%), Type IIb (1.6%) and Type III (2.4%) were seldom seen. Type I was more frequently seen in adult patients than in juveniles(P<0.05). Biopsy findings of 12 patients with quiescent disease showed active lesions in 7 patients. Eighty patients were followed up for a median duration of 36 months. Glucocorticoid was prescribed to 58 patients; cytotoxic agents were required for 16 of them; and remission was achieved in 57 patients. Bypass and endovascular interventional procedures were performed in 36 and 21 patients, respectively. Restenosis occurred in 34.7% of bypass procedures and 77.3% of endovascular interventional procedures. Conclusion: Diminished pulse is rarely seen in juvenile TA patients than in adults. Active vascular disorders may exist in patients with stable clinical manifestations. The incidence of restenosis is higher in endovascular interventional procedures than in bypass procedures.

Objective To study expression enhancement and significance of Y14 and Upf1 in human breast cancer cell lines and tissue. Methods Immuocytochemistry and laser scanning confocal microscope(LSCM) were applied. Y14 and Upf1 were determined in human breast cancer cell lines(MCF-7,ZR-75-30,T47D,MDA-MB435s,MDA-MB-453, MDA-MB-231) and breast epithelial cell line ( HBL-100). Results (1) Y14 and Upf1 level of breast cancer cells are obviously higher than that in breast epithelial cell line (P < 0. 05 ). (2)Y14 and Upf1 level of MDA-MB-231 are obviously higher than that in MCF-7. (3)The expression enhancement of Y14 and Upf1 level are obviously higher in human breast cancer tissue. Conclusion The expression level of Y14 and Upf1 in breast cancer cells and tissue enhance obviously.
