Objective To investigate the influence of atherosclerotic reference segments on coronary remodeling by intravascular ultrasound(IVUS) in patients with acute coronary syndrome(ACS). Methods One hundred and three consecutively enrolled patients [male 68 cases,female 35 cases,average age (60 ±11) years] with ACS were undergone by coronary artery angiography and IVUS with time selecting operation. The remodeling index(RI) was defined as lesion external elastic membrane cross section aere (EEM CSA) divided by the mean reference EEM CSA at the culprit vessel. Positive remodeling was RI≥ (67 cases), negative remodeling was RI <1(36 cases). The parameters of plaque were analysed between two remodeling groups, as well as compared between distal and proximal references. Results Only one patients do not have plaque at reference sites. In the analysis of 103 lesions and 102 reference sites, there were not significant different in plaque burden,plaque CSA,lumen CSA and lesion EEM CSA between two groups. Distal plaque burden[(39. 76 ±12. 54)% vs (32.38 ± 13.97)%, P <0.001] and plaque CSA [(6.14 ± 3.20)mm2 vs (4. 75 ± 3. 07) mm2, P = 0. 001] were larger than those at proximal reference. EEM CSA at distal reference was smaller than proximal one[(14. 99 ± 4. 12)mm2 vs (28. 37 ± 4. 48)mm2 , P <0. 001]. Plaque burden, plaque CSA and lumen CSA persented positive corelation between distal and proximal reference sites. Conclusions The reference segments lay a severe diffuse atherosclerosis in the group of ACS, which may influence assessment of coronary remodeling. Coronary remodeling as a process, a accurate evaluation could be result from the combination of static and serial approach by IVUS.

B-Raf kinase (BRAF) gene is a driver mutation,and is an effective target in the treatment of non-small cell lung cancer (NSCLC).Studies have shown that BRAF inhibitors are effective for treatment of NSCLC with BRAF mutant.It is important to understand the clinicopathologic features and the research progress of BRAF inhibitors for the individual treatment of NSCLC.

Objective To analyze the clinical characteristics,therapy and follow-up of the patients with ulcerative colitis (UC).Methods Collect the date of 77 inpatients with UC at the Second Affiliated Hospital of Chongqing Medical University be-tween November,2009 and october,2014,and assigned the patients randomly.Results 69.9% of the patients who were in the ac-tivity stage were moderate severity.E2 (46.6%,34/73)and E3 (50.7%,37/73)were the common lesions range.The main clinical manifestations were abdominal pain,diarrhea,mucopurulent bloody stool and bloody stool.The enteroscopy mostly showed that in-testinal mucosa hyperemia,eddma,erosion,and small ulcers had the common features of UC.The common biopsy results were chro-nic inflammation and/or erosion.The average value of serum ALB decreases while the severity of UC patients increases.Drug thera-py was the main treatment of UC.The maintenance therapy was aminosalicylic acid,the effective ratio of treatment is 89.0%(55/73).Conclusion UC treatment plan basically follow the consensus and we should enhance the follow-up of UC patients.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs)and anti-angio-genic drugs have individually demonstrated clinical benefit in the treatment of patients with advanced non-small cell lung cancer (NSCLC).Recent studies demonstrate that the combination of anti-EGFR and anti-angiogene-sis can more significantly enhance clinical benefit,and even can remit EGFR-TKIs resistance in the treatment of advanced NSCLC.According to the different kinds of anti-angiogenesis drugs,recent clinical studies mainly include the combination of anti-vascular endothelial growth factor monoclonal antibody bevacizumab plus EGFR-TKIs and multi-targeted receptor anti-angiogenic tyrosine kinase inhibitor plus EGFR-TKIs,and the for-mer results show a more significant improvement in terms of safety and efficacy in the treatment of advanced NSCLC.Therefore,the combination of bevacizumab plus EGFR-TKIs can be used as a new treatment standard in the treatment of some patients with NSCLC.

In an attempt to elucidate the morphologic changes of normal aging skin, the present study was undertaken in human facial and chest well skin of individuals aged from 4 months to 76 years old. Biopsied skin was studied with light microscope, scanning electron microscope, and transmission electron microscope, using both conventional and tannic acid staining. The morphologic changes in the skin were noted as follow: 1. Structurally, the aged epidermis gradually became somewhat thinner, with flattening of the dermoepidermal interface. The number of melanocytes also decreased. 2. Abnormalities of elastic fibers such as loss of oxytalan fibers were observed from age 30. It was the initial sign of the aging process of elastic fibers, followed by abnormal changes in elaunin and mature elastic fibers. The degree of facial skin abnormality was rather more severe than that of the chest wall skin. 3. In individuals more than 50 years old, the age related changes in mature elastic fibers were more severe. Transmission electron microscopically, the electron density in elastin was irregular. The elastic fibers also showed pores and irregular splitting with fragmentation. Fine granular materials were scattered near the elastin. 4. Scanning electron microscopically, the elastic fibers in young adult skin showd ribbon-like fibers aligned in the same direction. They were either cylindrical or elliptical, having smooth surface. In old skin, the elastic fibers ran in various directions, forming complicated networks. These were larger, more elliptical and more branched than those in young adult skin. In summary, histologic changes of aging are much more prominent in sun-exposed skin(facial skin) than in sun protected skin(chest wall skin). A completely different spectrum of elastic fiber abnormalities was found in individuals more than 30 years old. The result indicates that elastic fiber abnormalities are related to aging skin.

Objective To investigate the features of HIV-1-specific Cytotoxic T-Lymphocyte (CTL)responses in Chinese.Methods The HIV-1-specific CTL responses were analyzed in an IFN-?ELISPOT assay by using a matrix system containing 820 overlapping peptides spanning the entire HIV-1 Clade B and C consensus sequence.Results The HIV-1-specific CTL response almost clus- tered in Gag and Nef across either HIV-1 Clade B(HIV-1 B)or HIV-1 Clade C(HIV-1 C),while oth- er proteins could also be recognized at different level.In comparison of the response between HIV-1 Clade B and Clade C,the magnitude and frequency was roughly identical with some difference found at single-peptide level.The most frequently recognized peptides of HIV-1 B were located in Nef,GPKEP- FRDYVDRFYKTLR(5/17,29.4%)and Gag,LWVYHTQGYFPDWQNY(5/17,29.4%),while the most frequently recognized peptide of HIV-1 C was located in Gag GPKEPFRDYVDRFFKTLR(6/17, 35.29%).Conclusions HIV-1-specific CTL responses clustered within HIV-1 Gag and Nef in Chinese. However,there was some difference between HIV-1 B and HIV-1 C at single-peptide level.
