Objective To investigate the correlation between expression of vascular endothelial growth factor(VEGF) of serum and tumor tissues and the clinical prognosis in patients with breast cancer. Methods The expressions of VEGF level of serum and tumor tissues in 44 patients with invasive duct breast cancer, 13 with benign breast diseases and 40 healthy controls. Serum VEGF level was measured by ELISA method. The protein expression of tissue VEGF, ER and C-erbB-2 were evaluated by immunohistochemistry LSAB method. Results Serum VEGF level and tissue VEGF expression in breast cancer were higher than those in benign breast diseases (P0.05). VEGF expression was correlated with lymph node metastasis (P 0.05). Conclusion There is positively correlation between serum VEGF level and tissue VEGF expression, and between VEGF expression and clinic prognosis. Serum VEGF level may be one of important index of prognosis estimation in patients with breast cancer.

To analyze the prescription and medication regularities of traditional Chinese medicines in the treatment of melancholia in the Chinese journal full text database (CNKI), Wanfang Data knowledge service platform, VIP, Chinese biomedical literature database (CBM) in based on the traditional Chinese medicine inheritance support platform software, in order to provide reference for further mining traditional Chinese medicines for the treatment of melancholia and new drug development. The traditional Chinese medicine inheritance support platform software V2.0 was used to establish the prescription database of traditional Chinese medicines for treating melancholia. The software integrated data mining method was adopted to analyze four Qis, five flavors, meridian distribution, frequency statistics, syndrome distribution, composition regularity and new prescriptions. Totally 358 prescriptions for treating melancholia were analyzed to determine the frequency of prescription drugs, commonly used drug pairs and combinations and develop 22 new prescriptions. According to this study, prescriptions for treating depression collected in modern literature databases mainly have the effects in soothing liver and resolving melancholia, strengthening spleen and eliminating phlegm, activating and replenishing blood, regulating liver qi, tonifying spleen qi, clearing heat and purging heat, soothing the mind, nourishing yin and tonifying kidney, with neutral drug property and sweet or bitter flavor, and follow the melancholia treatment principle of "regulating qi and opening the mind, regulating qi and empathy".

In recent years, the targeted protein degradation technology has developed quickly, with proteolysis-targeting chimera (PROTAC) as the best-known strategy through exploring the ubiquitin-proteasome system. A number of new targeted protein degradation strategies have been emerging to expand the scope of protein degradation technology, including lysosome-targeting chimeras (LYTACs), autophagy-targeting chimeras (AUTACs), autophagosome-tethering compounds (ATTECs) and chimeras based on chaperone-mediated autophagy (CMA). The emerging methodologies have explored another important protein degradation system in eukaryotes-lysosomal systems, such as the endosome-lysosome pathway and the autophagy-lysosome pathway. This review summaries the mechanisms and features of different strategies for targeted protein degradation, with a special emphasis on the new targeted protein degradation technologies, such as their current status, advantages and limitations.

Objective To research and evaluate measuring Toric intraocular lens (Toric IOL) alignment by iTrace aberration without mydriasis.Methods Forty-five eyes of 35 patients underwent phacoemulsification in Tianjin Medical University Eye Hospital from June 2015 to February 2016 were enrolled.Follow-up and iTrace aberration examination were performed at postoperative 1 week.The internal optics aberration astigmatism axis was transformed into postoperative Toric IOL alignment.The result and the Toric IOL alignment measured by tradition slitlamp method were compared by linear correlation and difference.Results At postoperative 1 week,the uncorrected distant visual acuity and corrected distant visual acuity were (0.19 ± 0.12)LogMAR and (0.10 ±0.09) LogMAR.The UCVA was 20/40 or better in 42 eyes (93.3％).The mean IOL misalignment measured by slitlamp was (3.13 ± 2.86) degrees (ranged 0-9 degrees) and by the iTrace aberration was (4.44 ± 3.42) degrees(ranged 0-13 degrees),there was statistical significant difference (t =-2.321,P =0.025).The mean difference in the error of the Toric intraocular lens alignment measured by iTrace aberration and the slitlamp was (3.67 ± 3.59) degrees (ranged 0-14 degrees).The results showed that there was less than 5 degrees of difference between the two methods in 32 eyes (71.1％),locate 5 to 10 degrees in 9 eyes (20％),more than 10 degrees in 4 eyes (8.9％).The correlation between the 2 methods showed significant linear relationship (r =0.926,P ＜ 0.01).Conclusion Using iTrace aberration can accurately measure Toric intraocular lens alignment without mydriasis,the result has some reference value.

Objective To investigate the relationship between trace elements and rachitis in children.Methods Three hundred and twelve patients with rachitis and 297 healthy children were selected for this study.Blood zinc(Zn),iron(Fe),plasma copper(Cu),calcium(Ca),magnesium(Mg),lead(Pb) and cadmium(Cd) were assayed by atomic absorption spectrophotometer.Results The levels of Zn,Fe,Cu of rachitis in blood were significantly lower than those of healthy children,while the levels of Mg,Pb were higher.There were significant differences between 2 groups(P

Objective To explore the effect of levels and ratios of matrix nephritis metalloproteinase-2(MMP-2), -9 and inhibitor of metalloproeinase-1(TIMP-1) in the pathogenesis of children with Henoch-Schonlein purpura nephritis(HSPN),and the correlation between them and urinary micro albumin(MA).Methods Serum levels of MMP-2, -9 and TIMP-1 were determined by double antibody enzyme linked immunosorbent assay(ELISA),and urine MA was determined by immune rate nephelometry in 36 children with HSPN,16 children with simple purpura and 30 healthy controls.Results Levels of MMP-2, -9,TIMP-1 and ratios of MMP-2/ TIMP-1,MMP-9/TIMP-1 rose in acute phase of HSPN. The levels and ratios in HSPN group were higher than those in simple purpura group,and those in simple purpura group higher than those in controls (P

Objective To evaluate the early change of left ventricular (LV) systolic function in patients with type 2 diabetes mellitus(T2DM) by ultrasound speckle tracking imaging. Methods Ninety-five subjects were included:40 T2DM with normal LV ejection fraction (LVEF≥50% ,group A),20 T2DM with abnormal LVEF (LVEF<550 %) (group B), and 35 normal controls. Two-dimensional strain images were acquired from LV short-axis view. LV peak systolic global and segmental radial strain and circumferential strain at the levels of mitral annulus, papillary muscle and apex, and LV systolic global and segmental rotation at the levels of mitral annulus and apex and LV peak systolic global twist were assessed. Results In group A, compared with control group, LV peak systolic radial strain parameters were not significant difference (P >0.05), peak systolic circumferential strain of part segments, average peak strain of each plane and global strain were reduced (P <50.05～0.001) ,and LV peak systolic rotation of all apical segments, peak systolic global rotation at the levels of mitral annulus and apex,and peak systolic global twist were significantly increased (P <0.05～0.001). Compared with control group and group A,all LV systolic radial strain and circumferential strain parameters, LV systolic global and segmental rotation and peak systolic global twist in group B were significantly reduced (P <0.05 ～ 0.001). Conclusions Speckle tracking imaging could be used to evaluate the early change of LV torsional deformation and LV systolic function in T2DM.
