With the surge of high-throughput sequencing technology, it is becoming popular to perform the phylogenetic study based on genomic data. A bundle of new terms is emerging, such as phylogenomics, pharmacophylogenomics and phylotranscriptomics, which are somewhat overlapping with pharmaphylogeny. Phylogenomics is the crossing of evolutionary biology and genomics, in which genome data are utilized for evolutionary reconstructions. Pharmaphylogeny, advocated by Prof. Pei-gen Xiao since 1980s, focuses on the phylogenetic relationship of medicinal plants and is thus nurtured by molecular phylogeny, chemotaxonomy and bioactivity studies. Phylogenomics can be integrated into the flow chart of drug discovery and development, and extend the field of pharmaphylogeny at the omic level, thus the concept of pharmacophylogenomics could be redefined. This review gives a brief analysis of the association and the distinguished feature of the pharmaphylogeny related terms, in the context of plant-based drug discovery and sustainable utilization of pharmaceutical resource.

Objective To evaluate endoluminal repair and preoperative management for acute Standford type B aortic dissection complicating massive hydrothorax. Methods The clinical data of 27 patients (23 males, 4 females) hospitalized from January 2003 to December 2008 were analysed retrospectively. The average age was 47 ±9 years (35 ～70). Eleven patients had bilateral huge hydrothorax (40. 7% ) , while 13 had left hydrothorax (48. 1% ) and 3 had right hydrothorax (11. 1% ) only, and in 2 of them with additional pericardial effusion (7.4% ). SaO2 was below 90% in all cases. All patients underwent emergency endovascular repair. For control of massive hydrothorax found by CT or chest fluoroscopy, puncture drainage or tube drainage were administrated postoperatively. Results All the 27 operations were successful, and there was no perioperative mortality. Three type Ⅰ and one type Ⅳ endoleaks occurred but disappeared in one month. Hydrothorax disappeared 28 days to 3 months postoperatively in all patients, of which 5 cases had puncture drainage (18.5%) and 1 case had tube drainage ( 3. 7% ). Mean follow-up was 30 ± 20 m ( 6 ～ 78 m ) after endovascular management. Complications included pleural thickening (6 of 27, 22. 2% ) , pulmonary atelectasis (2 of 27, 7. 4% ) , and lung consolidation combined with chest dent (2 of 27, 7. 4% ). Conclusions Emergency endovascular therapy is safe and effective for acute Stanford type B aortic dissection with massive hydrothorax. Drainage of hydrothorax after stent-graft deployment is a must for the patient suffering from severe respiratory failure.

Objective To explore the surgical management for arterial diseases. Methods The clinical data of 86 cases of arterial diseases were analysed retrospectively. These cases included:3 cases of thoracic aortic aneurysm,2 cases of descending aortic dissection with rupture and aneurysm formation,2 cases of abdominal aortic dissection with false aneurysm,1 case of abdominal aortic aneurysm(AAA)with duodenojejunal fistula and GI bleeding,5 cases of ruptured AAA with shock, 3 cases of traumatic rupture of abdominal aorta,21 cases of AAA combined with unilateral or bilateral iliac aneurysms,6 cases of iliac aneurysms,9 cases of popliteal aneurysms,21 cases of false aneurysm of iliac or popliteal artery,1 case of rupture of junction of subclavian and vertebral artery with false aneurysm,3 cases of rupture of subclavian artery with false aneurysm,2 cases of aneurysm of carotid artery and 7 cases of false aneurysm of carotid artery. Prosthetic vascular graft was performed in 71(cases),autologous vein graft in 3 cases and suture(repair) of arterial rupture in 12 cases.Results Operative (mortalty) was 3.5%(3/86)in this series.Seventy-one cases were followed-up for 1 month to 5 years, the results showed that all the patients were alive and well.Conclusions In the(management) of(appropriate) aortic diseases, the use of endoluminal technique is simple, microtraumtic, safe and has few complications. It also can shorten the hospital stay of the patient. Endovascular technique should be the first choice for patients with aortic diseases.

Objective To study inflammatory reaction induced by N-protein of severe acute respiratory syndrome(SARS)-coronavirus(CoV)in human alveolar typeⅡepithelial cell(A549). Methods Effects on growth of A549 cell by N-protein of SARS-CoV:activity of A549 cells was determined by thiazylyl blue colorimetry assay at 24,48,72 and 96 h,respectively.Effects on cyto- kine production by A549 cells exposed to N-protein of SARS-CoV:interleukin(IL)-6,IL-10 and transforming growth factor-?1(TGF-?1)concentration in culture supernatant were determined by enzyme-linked immunosorbent assay(ELISA).Effects on mRNA expression of cytokine of A549 cells and matrix metalloproteinases-9(MMP-9)exposed to N-protein of SARS-CoV:total RNA of A549 cells was extracted using Rneasy mini kit;RT-PCR was employed to measure the mRNA expression of IL-6,IL-10,TGF-?1 and MMP-9 semiquantitatively.Results Different concentrations of N-protein could all inhibit the growth of A549 cells(after 48 h)and the inhibition by 20?g/mL pro- tein was the strongest.Compared with the control group(0.737?0.024,0.968?0.007),the A val- ues of experimental groups at 72 h and 96 h(0.672?0.027,0.799?0.092)decreased obviously (P

With the widespread clinical application of neoadjuvant chemotherapy, it has become an essential part of combination therapy for patients with breast cancer. However, a rapid, accurate, and effective approach for assessing the therapeutic efficacy of neoadjuvant chemotherapy is unavailable. Routine physical examinations cannot provide effective clinical evaluation. Although imaging techniques play an important role in evaluating the therapeutic effect of neoadjuvant chemotherapy, this is limited because it only detects morphologic changes. Blood oxygen detection for breast diseases is an emerging diagnostic technique that has distinctive merit in assessing the efficacy of chemotherapy. Biologic markers are becoming more important in assessing the effect of neoadjuvant chemotherapy for patients with breast cancer. This review summarizes the principles and the current applied practice of these approaches to evaluate the effect of neoadjuvant chemotherapy for patients with breast cancer.

Heat shock protein 70 (Hsp70) is a class of molecular chaperones essential for maintaining protein homeostasis in cells. Hsp70s also play important roles in the pathogenesis of a variety of diseases, including cancer, neurodegenerative diseases and infectious diseases, which makes them potential targets for the treatment of these diseases. It is necessary to develop small molecule inhibitors to validate this class of important therapeutic targets. In recent years, the discovery of small molecule inhibitors for Hsp70s has made remarkable progress, and Hsp70 inhibitors with different modalities have been reported. In this paper, Hsp70 and relevant diseases are briefly introduced, and the discovery of Hsp70 small molecule inhibitors with distinct modalities are summarized, providing reference for the further discovery and development of Hsp70 small molecule inhibitors.

BACKGROUND: Acetabular cup orientation using a standard radiograph of the pelvis is quite common method to assess artificial hip replacement nowadays. Non-standardization of pelvic orientation affected accuracy of measurement results, and it is difficult to compare. OBJECTIVE: To make sure how pelvis tilting affect the anteveration of the cup and to elevate clinical accuracy and compare study comparability. METHODS: Designed a simulated acetabular cup with serial concentric circles which pass through the same polars and represent anteveration of 0°, 10°, 20°, 30°, 40°, Loaded the simulated acetabular cup at an inclination of 35°, 40°, 45°, 50°, 55° to6 cadaver pelves, Made the pelves tilt around the frontal axis and sagittal axis with 5° each time in a scope of+30°. Takestandard radiograph of the pelvis accordingly. Radiograph was photographed end frontal angle of dip was measured. RESULTS AND CONCLUSION: Pelvic tilt of about 1° causes measuring errors of anteveration 0. 61 °-0. 73°. The anteveration decreased at both acetabular cups when pelvic posterior tilt and at the acetabular cup that near the X-ray source as pelvic lateral tilt. The anteveration rose at both acetabular cups when pelvic anterior tilt and at the acetabular cup that away from the X-ray source as pelvic lateral tilt. During clinical evaluation, pelvic orientation effects on measurement results should be considered.

Objective To retrospectively determine the features of stones and calcifications in hepatobiliary system on virtual nonenhanced (VNE) dual-energy computed tomography (CT), and to evaluate the possibility of VNE images in diagnosis for those lesions.Methods A total of 128 gall stones and calcifications of the liver found in 110 patients were examined with triple phase abdominal CT scan from July 2007 to December 2011, in which true nonenhanced (TNE) phase and arterial phase were performed with single-energy CT (120 kVp) and portal venous phase was performed with dual-energy CT (100 kVp and 140 kVp). VNE images were generated from the portal venous phase dual-energy CT data sets by using commercially VNC software. The mean CT values for the stone, liver, bile and paraspinal muscle, mean lesion density and size in area dimension, contrast-to-noise ratio (CNR) of lesion to the liver or bile, and image noise were assessed and compared between VNE and TNE images. The effective dose and size-specific dose estimate (SSDE) were also calculated.Results The mean CT values of the lesions measured on VNE images declined significantly compared with those measured on TNE images (164.51±102.13 vs. 290.72±197.80 HU, P<0.001), so did the lesion-to-liver CNR (10.80±11.82 vs.18.81±17.06, P<0.001) and the lesion-to-bile CNR (17.24±14.41 vs. 21.32±17.31, P<0.001). There was no significant difference in size of lesions area between VNE and TNE images (0.69±0.88 vs. 0.72±0.85 cm, P=0.062). Compared to the 128 lesions found in TNE images, VNE images showed the same density in 30 (23.4%) lesions, lighter density in 88 (68.8%) lesions, while failed to show 10 (7.8%) lesions, and showed the same size in 61 (47.7%) lesions and smaller size in 57 (44.5%) lesions. The CT cutoff values of lesion and size were 229.21 HU and 0.15 cm, respectively. The total effective dose for triple phase scan protocol with TNE images was 19.51±7.03 mSv, and the SSDE was 39.84±11.10 mGy. The effective dose for dual phase scan protocol with VNE images instead of TNE images was 13.29±4.89 mSv, and the SSDE was 27.83±9.99 mGy. Compared with TNE images, the effective dose and SSDE of VNE images were down by 32.05%±3.69 % and 30.63%±2.34 %, respectively.Conclusions Although the CT values and CNR of the lesions decreased in VNE images, the lesions of which attenuation greater than 229.21 HU and size larger than 0.15 cmcould be detected with good reliability and obvious dose reduction. There was good consistency in the size of stones and calcifications in hepatobiliary system between VNE images and TNE images, which ensured the possibility of the clinical application of VNE images.
