Objective To explore the application of three-dimensional (3D) ultrasonography in screening the defects of fetal brain and skull.Methods Thirty-one cases of the fetal were detected in 3D ultrasonography.The ultrasonic data were compared with magnetic resonance imaging(MRI) and pathology.Results Among 31 cases according to 3D ultrasonography,there were 2 of anencephaly, 1 of exencephaly,2 of encephalocele,5 of holoprosencephaly,2 of arachnoidcyst, 1 of vein of Galen aneurysm,2 of agenesis of the corpus callosum, 1 of schizencephaly, 3 of Dandy-Walker syndrome, 7 of ventriculomegaly, and 5 of enlargement of cisterna magna.Compared with the results of MRI,the diagnostic accordance rate was 100% by 3D,it was 93.5% by 2D.Conclusions The structure of fetal brain and skull were viewed more clearly in 3D ultrasonography than 2D ultrasonography and the defects of fetal brain and skull can screened more exactly.

Tangcao pill is commonly applied in adjuvant and even alternative therapy for patients with AIDS. However, the herb contains complex ingredients, but with unknown effect against anti-HIV drug and unknown function. Because CYP450 emzyme is the main metabolic enzymes of the drug, it is of important significance to study the regulation of CYP450 enzymes before and after the combined administration of Tangcao pill and EFV. Proteomics, due to its high throughout and high sensitivity, has been widely applied in CYP450 enzyme study. In this paper, liver microsomes were separated through differential centrifugation. Their proteins were separated through SDS-PAGE. The three protein bands that CYP450 enzymes were located were cut and identified by liquid chromatography tandem mass spectrometry. Totally 16 CYP450 isoenzymes were identified. Furthermore, in order to make a quantitative analysis on the effect of tang herb on CYP450 emzyme, the multiple reaction monitoring (MRM) technology based on MS was adopted. The CYP2C11 was selected based on the results of the mass spectrum identification of proteins. The characteristic polypeptides were obtained through searching Expasy blast database. The m/z of the fragment ions was less than 800. In the paper, the m/z of ion pairs of CYP2C11 were 711.5/232.1, 711.5/319.2, 711.5/466.2 and 711.5/595.3, and the m/z of ESAT-6 (internal standard, IS) were 735.5/215.3, 735.5/389.3, 735.5/460.3 and 735.5/524.3. The relative peak (analyte/IS) area was adopted for the relative quantitative analysis. Compared with the EFV single administration group, the EFV and Tangcao pill combined administration group showed a 1.6-fold increase in CYP2C11. The results of the paper indicated that Tangcao pill may affect drug metabolism by regulating metabolic enzymes such as CYP2C11, but the specific mechanism still unknown.

Objective:To investigate the effect of huaier granule combined with docetaxel + epirubicin + cyclophosphamide (TEC) neoadjuvant chemotherapy on the disease control rate and the levels of extracellular fragment of human epidermal growth factor receptor 2 (HER2-ECD) and tumor abnormal protein (TAP) in patients with advanced breast cancer.Methods:From April 2013 to June 2016, 94 patients with advanced breast cancer in Shengjing Hospital Affiliated to China Medical University were selected and randomly divided into observation group ( n=47) and control group ( n=47). The control group was treated with TEC neoadjuvant chemotherapy, and the observation group was treated with TEC neoadjuvant chemotherapy combined with huaier granules for 12 weeks. The curative effect, incidence of adverse reactions, cellular immune function indexes (CD8 + , CD4 + , CD4 + /CD8 + ), serum HER2-ECD and TAP levels were compared before and 12 weeks after treatment. The patients were followed up for 3 years after treatment, and the 1-year, 2-year and 3-year survival rates were compared between the two groups. Results:After 12 weeks of treatment, the disease control rate of the observation group was higher than that of the control group, with statistically significant difference ( P<0.05); during the treatment, the incidence of gastrointestinal reaction, neutropenia, thrombocytopenia and abnormal liver function of the observation group was lower than that of the control group, with statistically significant difference ( P<0.05); after 12 weeks of treatment, the serum CD8 + level of the observation group was lower than that of the control group, and the serum CD4 + , CD4 + /CD8 + level was higher than that of the control group, with statistically significant difference ( P<0.05); after 12 weeks of treatment, the serum levels of HER2-ECD and TAP in the observation group were lower than those in the control group, with statistically significant difference ( P<0.05); the 3-year survival rate in the observation group was higher than that in the control group, with statistically significant difference ( P<0.05). Conclusions:Huaier granules combined with TEC neoadjuvant chemotherapy in patients with advanced breast cancer can reduce serum HER2-ECD, TAP levels, which can enhance the immune function of the body, reduce the toxic and side effects, improve the long-term survival rate, and have a significant effect.

Pulmonary arterial hypertension (PAH), also named as a cancer of cardiovascular disease, is a rare disease and has complicated pathogenesis. Recently, there are more understandings of PAH pathogeneses. According to the pathogenesis and active pathways, the clinically used drugs are classified into several groups incluidng prostacyclin analogues and prostacyclin receptor agonists, endothelin receptor antagonists, phosphodiesterase-5 inhibitors, soluble guanylate cyclase inhibitors, etc. To elevate the efficacy of the drugs, numerous drug delivery systems are developed. This review mainly summarized the pathological mechanism of PAH, drugs and drug delivery approaches in the treatment of PAH.

Electronic case report forms (eCRFs) instead of the traditional paper case report forms (pCRFs) are increasingly used by investigators and sponsors of clinical research. We include a total of 14 phase III studies (8 pCRF, 6 eCRF) to compare paper and electronic data documentation both quantitatively and qualitatively in clinical studies. The result suggests that adaptions of electronic data capture (EDC) in clinical trials have the advantages in optimization of data capture process, improvement of data quality and earlier clinical decision compared to paper-based methods. Furthermore, the successful implementation of EDC requires accouplements with corresponding data management processes and reallocation of resources.
