Objective To explore the endoscopic features and careinoembryonic antigen (CEA) ex-pressions of colorectal serrated adenomas (SA). Methods From June 2005 to July 2008, 27 patients with colorectal polyps and 26 cases of advanced colorectal cancer (ACC) were enrolled in the study. The pit pat-tern of the suspected lesions were observed with 0. 4% indigo carmine sodium stain and classified according to Kudo classification. The polyps were removed by biopsy, high-frequency electrical excision or endoscopic mucosa resection and the samples of ACC were collected with biopsy forceps. All specimens underwent rou-tine pathological examination and CEA expression was detected by immunohistochemistry. Results There were 47 SAs and 27 other types of polyps in polyp group. Most SAs located in left-side colon and were char-acterized by the bulge semipedunculation. The diameters of 45 serrated adenomas ranged from 3 to 8ram, and the maximal diameter of other 2 were more than 10ram. The most common type of pit pattern in SA was mixed type Ⅱ and ⅢL, with type Ⅱ predominant in a certain percentage. Expression of CEA in SA glands was significantly higher than that in proliferative polyps (P < 0. O1). Candnsion SA is an unique type of colorectal adenoma, which is capable of expressing CEA, and displays malignant potential and deserves great attention.

Objective To observe the clinical therapeutic effects and evaluate the security of Huganjiexian decoction combined with conventional therapy on hepatic cirrhosis.MethodsBy the randomized and prospective study method,34 patients with liver cirrhosis were divided into experimental group and control group.The experimental group was treated with Huganjiexian decoction combined with conventional therapy while the control group was treated with conventional therapy alone.Patients in both groups were treated six months.At the beginning and 6 months after treatment,levels of alanine transaminase (ALT),aspartate transaminase (AST),albumin (ALB),albumin/globulin (A/G),total bilirubin (TBiL),blood urea nitrogen (BUN),serum creatinine (Scr) were determined.Results Levels ofALT、AST、TBiL decreased in both groups after being treated for six months,and the differences of downward trend of the experimental group were more significant than control group (F=36.63,40.31,38.65,P＜0.05).Levels ofALT、AST、TBiL of the experimental group were lower than those of control group significantly (F=8.67,7.62,4.36,P＜0.05 ).The A/G raised in both groups after treatment,and the upward trend of the experimental group was greatly different from that of control group (F=24.10,P＜0.05),the value of A/G of the experimental group was higher than that of control group (F=4.78,P＜0.05).The ALB raised in both groups after treatment,while the upward trend of the experimental group was no different from that of control group (F=0.89,P＞ 0.05).Thevalue of ALB had no significant changes in both groups (F=3.15,P＞0.05).Conclusion Huganjiexian decoction possessed therapeutic effect on hepatic cirrhosis,it had no obvious toxicity and side

Cytoplasmic processing bodies, termed P bodies, are involved in diverse post-transcriptional processes including mRNA decay, nonsense-mediated RNA decay (NMD), RNAi, miRNA-mediated translational repression and storage of translationally silenced mRNAs. Regulation of the formation of P bodies in the context of multicellular organisms is poorly understood. Here we describe a systematic RNAi screen in C. elegans that identified 224 genes with diverse cellular functions whose inactivations result in a dramatic increase in the number of P bodies. 83 of these genes form a complex functional interaction network regulating NMD. We demonstrate that NMD interfaces with many cellular processes including translation, ubiquitin-mediated protein degradation, intracellular trafficking and cytoskeleton structure.We also uncover an extensive link between translation and RNAi, with different steps in protein synthesis appearing to have distinct effects on RNAi efficiency. Moreover, the intracellular vesicular trafficking network plays an important role in the regulation of RNAi. A subset of genes enhancing P body formation also regulate the formation of stress granules in C. elegans. Our study offers insights into the cellular mechanisms that regulate the formation of P bodies and also provides a framework for system-level understanding of NMD and RNAi in the context of the development of multicellular organisms.

Objective:To explore the correlation between fibular head height and varus knee osteoarthritis occurrence and severity.Methods:A retrospective analysis was performed on 618 participants (618 knees, 184 males and 434 females, mean age 61.12±10.98 years) who underwent standard weight-bearing full-leg radiographs and were diagnosed as non-knee osteoarthritis or varus knee osteoarthritis from January 2019 to June 2019. Knee osteoarthritis was diagnosed according to Kellgren-Lawrence grading: 0-I grades were diagnosed as non-osteoarthritis, II-IV grades were diagnosed as osteoarthritis. Joint line convergence angle (JLCA), medial proximal tibial angle (MPTA) and hip-knee-ankle angle were measured on X-rays to reflect varus deformity. The fibular head height was defined as the vertical distance from upper edge of fibular head to lateral tibial plateau. Patients were divided into 5 groups according to Kellgren-Lawrence grading. Differences of age, gender, height, weight, body mass index, varus deformity (JLCA, MPTA and hip-knee-ankle angle) between Kellgren-Lawrence 0-IV grades were compared. Ordinal logistic regression was performed to analyze the correlation between fibular head height and Kellgren-Lawrence grades. Pearson's correlation analysis was used for the correlation among fibular head height, JLCA, MPTA and hip-knee-ankle angle, and the main factor of JLCA, MPTA and hip-knee-ankle angle was extracted by factor analysis. Multiple linear regressions were used to analyze the correlation between fibular head height and varus deformity score.Results:There were 68, 66, 97, 98, 289 participants in Kellgren-Lawrence grades 0-IV respectively that was 134 participants were diagnosed as non-osteoarthritis and 484 participants were diagnosed as osteoarthritis. Fibular head height and MPTA showed a decreasing trend ( F=129.076, 24.875; P<0.001) while JLCA and hip-knee-ankle angle showed an increasing trend ( F=414.346, 105.996; P<0.001) with the increase in Kellgren-Lawrence grading. Age, body mass index and fibular head height are influencing factors of Kellgren-Lawrence grading with OR(95%CI) were 1.116(1.093, 1.141), 1.363(1.060, 1.754), 0.617(0.575, 0.662) . Fibular head height was negatively correlated with JLCA and hip-knee-ankle angle ( r=-0.641, -0.478; P<0.001) , respectively, and positively correlated with MPTA ( r=0.320, P<0.001). There were significant correlations between age, fibular head height and the varus deformity score ( β=0.274, -0.457; P<0.001). Conclusion:Fibular head height of patients with varus knee osteoarthritis is lower than that of non-osteoarthritis. In addition to age and body mass index, fibular head height is a risk factor for varus knee osteoarthritis occurrence. The smaller the fibular head height is, the more serious the osteoarthritis severity and varus deformity are.
