Cloning, expression, and characterization of Der f 7, an allergen of Dermatophagoides farinae from China

A full-length cDNA encoding house dust mite allergen Der f 7 from Dermatophagoides farina (Acari: Pyroglyphidae) from China was cloned, sequenced, and successfully expressed. A reference sequence (GenBank accession AY283292) was used to design polymerase chain reaction primers. Analysis revealed eight mismatched nucleotides in five Der f 7 cDNA clones, and the projected amino acid sequence contained six incompatible residues. These results suggest that the sequence of Der f 7 may be polymorphic. Further bioinformatic analysis revealed that the mature Der f 7 allergen had a molecular mass of approximately 21.88 kDa and a theoretical isoelectric point of 4.90. Der f 7 protein secondary structure was composed of a helix (56.63%), extended strand (5.10%), and random coil (38.27%). Group 7 allergens are present in Pyroglyphidae, Acaridae, and Glycyphagidae families, and homology analysis revealed a 86% similarity between Der f 7 and Der p 7. Furthermore, a phylogenetic tree constructed of group 7 allergens from different mite species revealed that Der f 7 and Der p 7 clustered with 100% bootstrap support. Bioinformatics-driven characterization of Der f 7 allergen as conducted in this study may contribute to diagnostic and therapeutic applications for dust mite allergies.

早期肠内营养对机械通气老年患者的临床作用

目的早期肠内营养对机械通气老年患者的临床作用。方法按是否在机械通气48h内开始肠内营养支持治疗,将56例老年机械通气患者分为早期肠内营养组38例和非早期肠内营养组28例,在摄入相当热量和氮量的条件下观察两组患者机械通气时间、平均住院时间、发生呼吸机相关性肺炎(VAP)的病例数和死亡病例数、出院时/死亡前APACHEⅡ评分。结果早期肠内营养组和非早期肠内营养组机械通气时间、平均住院时间、VAP病例数、死亡病例数分别为(20.5±8.6)d/(32.4±11.0)d、(37.4±16.5)d/(66.7±26.2)d、25例/21例、11例/12例,经统计学处理差异有显著性(P<0.05);而APACHEⅡ评分为(22.7±12.9)分/(24.5±15.3)分,经统计学处理差异无显著性(P>0.05)。结论早期肠内营养能明显缩短老年机械通气患者机械通气时间和住院时间,降低呼吸机相关性肺炎的发生率和病死率。     

Prognostic significance of BMP7 as an oncogene in hepatocellular carcinoma

This study aims to evaluate the association between BMP7 tissue expression and patient prognosis in hepatocellular carcinoma (HCC). The expression of BMP7 mRNA in HCC was characterized using real-time PCR and 30 pairs of fresh frozen HCC tissues and corresponding noncancerous tissues. BMP7 protein expression in HCC was confirmed using immunohistochemistry on a tissue microarray chip. Finally, BMP7 expression was correlated with conventional clinicopathological features of HCC and patient outcome. The expression of BMP7 mRNA and protein in HCC cells was much higher than in normal hepatic cells. Our results showed that the high expression of BMP7 in HCC was related to tumor size (p?<?0.001), histological differentiation (p?=?0.041), serum AFP (p?=?0.007), and tumor stage (p?<?0.001). Kaplan–Meier survival analysis showed that a high-expression level of BMP7 resulted in a significantly poor prognosis of HCC patients. Multivariate analysis revealed that BMP7 expression level was an independent prognostic parameter for the overall survival rate of HCC patients. These findings provide evidence that a high-expression level of BMP7 serves as a biomarker for poor prognosis for HCC. Thus, we speculate that BMP7 may be a potential target of antiangiogenic therapy for HCC.     

胃癌组织中c-Met的表达及其临床意义

目的：研究c-Met在胃癌组织中的表达及其临床意义。方法：收集2011年1月至2011年12月盐城市第一、三人民医院外科接诊、手术切除并经病理证实的胃癌石蜡标本69例,另取同期胃黏膜不典型增生组织标本20例以及正常胃黏膜标本20例作对照。采用免疫组织化学法检测胃癌组织中c-Met蛋白的表达,采用real-time PCR法检测15例手术切除的胃癌和癌旁组织中c-Met mRNA的表达。采用Spearman秩相关分析评估c-Met蛋白与胃癌标志物骨桥蛋白（osteopontin,OPN）、基质金属蛋白酶（matrix metalloproteinase,MMP）表达的关系。结果：c-Met蛋白在胃癌组织中的阳性表达率为65.2%, 明显高于胃黏膜不典型增生组织（30%）及正常胃黏膜组织(20%,均P<0.01）;c-Met蛋白表达与胃癌的淋巴结转移、临床TNM分期相关（P<0.01)。胃癌组织中c-Met mRNA的表达显著高于正常胃黏膜组织\[（0.20±0.12） vs （0.03±0.02）,P<001\]。OPN、MMP-9蛋白的表达与胃癌的浸润、临床TNM分期、淋巴结转移相关,且c-Met蛋白的表达与OPN、MMP-9的表达呈正相关（P<0.05）。结论：c-Met在胃癌组织中高表达,在胃癌的发生、发展过程中具有重要的作用,与OPN、MMP-9可能存在一定的协同性     

Association of CYP2B6 gene polymorphisms and anti-tuberculosis drug-induced hepatotoxicity in a Chinese population

ObjectivesAntituberculosis drug-induced hepatotoxicity (ATDH) remains a common and severe challenge in tuberculosis (TB) chemotherapy. A growing number of studies have revealed that genetic polymorphisms affect an individual's susceptibility to ATDH. The aim of this study was to explore the role of cytochrome P450 family 2 subfamily B member 6 (CYP2B6) gene polymorphisms in the development of ATDH in Chinese TB patients.MethodsCYP2B6*6 genotypes were determined in TB patients with and without ATDH. Association between polymorphisms and risk of ATDH was estimated by multiple logistic regression analysis.ResultsA total of 343 eligible TB patients (166 with ATDH; 177 without ATDH) were included in this study. Analysis of all subjects revealed no statistical differences in genotype distribution between the two groups. However, the CYP2B6 *6/*6 genotype was significantly associated with decreased risk of ATDH in the male subgroup (P = 0.039, OR = 0.097, 95% CI: 0.011–0.885). Furthermore, in male patients, the presence of the CYP2B6*6 allele was significantly higher in the non-ATDH group compared with the ATDH group (26.2% vs. 15.5%, P = 0.020, OR = 0.522, 95% CI: 0.301–0.903).ConclusionsThis study is the first to demonstrate an association between CYP2B6 polymorphisms and the risk of ATDH in the Chinese population. We have shown that males who have the CYP2B6 *6/*6 genotype may be less susceptible to the development of ATDH. Further studies are required to confirm this genetic association result.

全膝关节置换中是否需要髌骨置换

背景：全膝关节黄换中髌骨冠换与否一直存在争议。目的：对临床全膝关节簧换中是否进行髌骨簧换进行对比观察。方法：随机选取2009年7月至2012年4月在曲城市第一人民医院膝关节骨性关节炎患者56例,兆60膝,按全膝关节置换时是否进行髌骨置换分为髌骨置换组和髌骨未置换组。结果与结论：令膝关节置换3个月后,髌骨置换组忠者在膝关节功能评定量表评分、髌骨评分、活动度和Q角与髌骨未置换组比明显降低（P〈0．05）,而膝前痛评分和膝外翻角与髌骨未置换组患者的差异无显著性意义（P〉0．05）。提示全膝关节置换中合理进行髌骨处理可有效改善髌股关节运动轨迹,明混降低髌骨并发症。对于髌股关节匹配及力线良好的忠者保留髌骨可提高关节的功能恢复,在全膝关节胃换中进行髌骨置换较髌骨不置换总休效果好。
