ABSTRACT
OBJECTIVE@#To analyze the correlation between the mRNA levels of breast cancer resistance protein (BCRP) and lung-specific X protein (LUNX) genes with pathological types and stages of patients with non-small cell lung cancer (NSCLC) and their significance for prognosis.@*METHODS@#Eighty nine patients with NSCLC admitted to Huaihe Hospital of Henan University between June 2015 and June 2018 were recruited, with 55 patients with benign lung lesions admitted during the same period of time selected as the control group. The mRNA levels of BCRP and LUNX genes were detected in the peripheral blood samples from the two groups, and their correlation with the clinicopathological characteristics and prognosis of the patients was analyzed.@*RESULTS@#The expression rates of BCRP and LUNX mRNA in the NSCLC group were significantly higher compared with the control group (P < 0.05). The level of BCRP mRNA of the NSCLC patients has correlated with the degree of differentiation and TNM staging (P < 0.05), but not with gender, age, smoking, pathological types and lymph node metastasis (P > 0.05). The level of LUNX mRNA of them has correlated with the degree of differentiation, TNM staging and lymph node metastasis (P < 0.05), but not with gender, age, smoking, and pathological types (P > 0.05). Compared with those with no expression, the overall survival rate of patients with BCRP and LUNX expression was significantly lower (P < 0.05). The degree of differentiation, TNM staging, lymph node metastasis, and expression of the BCRP and LUNX mRNA may all affect the prognosis of the patients.@*CONCLUSION@#The levels of BCRP and LUNX mRNA in the peripheral blood of patients with NSCLC are significantly increased. The expression of BCRP mRNA is correlated with the degree of differentiation and TNM staging, whilst the expression of LUNX mRNA is correlated with the differentiation degree, TNM staging and lymph node metastasis. Both may be used as independent predictors for the prognosis of patients with NSCLC.

Renal fibrosis is the main pathological foundation of chronic kidney diseases progressing to end-stage renal diseases. With complex pathogenic factors and prolonged disease course， it threatens the quality of life of patients and brings about heavy financial burden to medical care. In the instance of intestinal flora disturbance， the internal homeostasis is broken， resulting in various "imbalances". The "combination of state and target" endows the syndrome differentiation-based treatment of renal fibrosis with new connotation from the perspective of intestinal flora reconstruction and microbial diversity restoration. In addition， traditional Chinese medicine （TCM）-targeted intervention of intestinal microecology has unique advantages under the principle of "treating different diseases with the same method"， which can guide the diagnosis and treatment of renal fibrosis. To be specific， TCM emphasizes macroscopic regulation of state and microscopic targeting. In view of the inflammatory response， accumulation of endotoxin， and excessive deposition of extracellular matrix （ECM） in the process of renal fibrosis， the strategies for treating this disease have been developed， such as alleviating dampness，removing turbid toxin， and relieving deficiency and stasis. Famous prescriptions in ancient books or compound Chinese medicine prescriptions， classical formulas， Chinese medicine monomers， or active components of Chinese medicine target intestinal microecology. Therefore， from the perspective of common pathogenic factors of renal diseases （renal fibrosis） or pathological product-intestinal microecological imbalance， this article combines TCM basic theory with modern medical pathogenesis， and summarizes the research on TCM intervention of renal fibrosis by regulating intestinal microecology and the scientific connotation of renal fibrosis， which is expected to provide ideas and methods for the product development and related preparations and in-depth molecular biological research.

ABSTRACT
BACKGROUND:The articular cartilage has weak self-repair ability, mainly due to its lack of trophoblast cels in blood vessels and slow cel metabolism. Current treatment methods cannot restore the original function of the cartilage tissue, and cartilage tissue engineering in recent years has garnered increasing attention. OBJECTIVE:To observe the effect of adipose-derived stem cels transfected with bone morphogenetic protein 14 combined with type I colagen sponge scaffold on the repair of articular cartilage injury in the knee of rabbits. METHODS: Adipose-derived stem cels were isolated and cultured from rabbit subcutaneous adipose tissue, and transfected with Ad-CMV-BMP-14-IRES-hrGFP-1. Type I colagen sponge scaffold with the transfected adipose-derived stem cels was used to repair articular cartilage injury in the knee of rabbits. Twelve weeks after operation, the articular tissue was taken for gross assessment and histological evaluation. RESULTS AND CONCLUSION: The expressions of bone morphogenetic protein 14, type II colagen and Sox-9 were higher in cels transfected with bone morphogenetic protein 14 than untransfected ones. At 12 weeks after operation, adipose-derived stem cels transfected with bone morphogenetic protein 14 combined with type I colagen sponge scaffold had good repair effect on articular cartilage injuries, and the injured cartilage tissues were smooth and had good texture, color and integration junction; adipose-derived stem cels combined with type I colagen sponge scaffold could partialy repair the injured cartilage tissues that had similar color and texture to normal tissues, and there was a remarkable boundary between the repaired tissue and normal cartilage tissue;simple type I colagen sponge scaffold was almost colapsed, and no hyaline cartilage tissue formed. These findings indicate that transfection of bone morphogenetic protein 14 can strengthen the ability of adipose-derived stem cels dramaticaly to repair cartilage injuries.
ABSTRACT
Objective To conduct comparative study of healthy vertebral artery (VA) blood flow of subjects from plain and plateau region using color Doppler ultrasound (CDUS) measurement,and to investigate the influence of plateau on blood flow of VA.Methods One hundred and thirty-five subjects from plain region and eighty from high altitude region were recruited.Time averaged maximum velocity and inradium (D) of VA were measured with CDUS technology.Unilateral VA blood flow and total blood flow were calculated.Peripheral blood viscosity measurement was carried out by testing low cut,mid cut,high cut,plasma viscosity and red blood cell count (RBC),hemoglobin concentration (HGB),hematocrit (HCT).Results VA diameter,blood viscosity,RBC,HGB,and HCT of plateau group are all higher than that of the plain group (P＜0.05),while the total blood flow was lower than that of plain group and the value of male was higher than that of female (P＜0.05).The inradiums of right side VA were larger than that of the left side (P＜0.05) in plain group,while no difference was observed in plateau group (P＞0.05).Conclusions Long term (＞10 years) living in plateau hypoxia (altitude＞3 000 m) environment can reduce the average flow velocity and the blood flow of VA.

ABSTRACT
Objective: To compare the sequence diversity of HVR1 in the putative envelope protein E2 of the genotypeⅡand genotype Ⅲ HCV in Chinese. Methods: The cDNAs[nucleotide(nt)1449-1586(HCV-J) or nt1460-1582(HCV-J6)] derived from plasma of 55 patients infected with genotype Ⅱ HCV and 38 patients infected with genotype Ⅲ HCV were amplified,purified and directly sequenced by RT-nested polymerase chain reaction(PCR) and dideoxynucleotide chain termination method. Results: The HVR1 was found in amino acid(aa) 384-408 positions of both types HCV E2 protein. There were 5 similar conserved amino acids in 2 types HCV HVR1:aa385(Thr), aa389, 390, 406(Gly)and aa403(Phe).Besides, 401(Ser) was also highly conserved in genotype Ⅱ HCV HVR1. Although the variation characteristic of 2 types was similar, but the sequence diversity(SD),the kinds and frequency of some amino acids in some HVR1 positions and the conserved region near the HVR1 had some differences between 2 genotypes. Conclusion: Further study on the diversity of HVR1 and its biological significance will be helpful to understand the mechanism of HCV persistent infection and the development of HCV vaccine.
