Objective:To evaluate the effectiveness and safety of the home-made umbrella-shaped Octoparms inferior vena cava filter in the prevention of pulmonary embolism.Methods:A multicenter, randomized, positive parallel controlled, non-inferiority clinical trial was conducted in ten hospitals in China from October 2017 to March 2019. A total of 188 subjects were enrolled according to the same inclusion and exclusion criteria in different institutes. The 188 subjects were randomly divided into the trial group or the control group according to 1∶1 by the central randomization system, with 94 cases in each group. Octoparms inferior vena cava filter was used in the trial group, and the Celect inferior vena cava filter in the control group. The primary effective index was clinical success rate,including the clinical success rate of filter placement and filter retrieval. The secondary index included the rate of manual success of the delivery sheath system,incidence of pulmonary embolism(within 6 months), incidence of filter fracture,migration (>20 mm),tilt(>15°) on insertion/retrieval,and the situation of inferior vena cava flow(within 6 months). Safety evaluation included the incidence of filter related complications and device-related adverse events immediately after surgery and during follow-up.Results:The success rate of implantation was 100% in 188 subjects. Filter retrieval was performed in 87 cases (92.55%) in the trial group and 91 cases (96.81%) in the control group. The clinical success rate of the trial group was 97.87%(92/94) and that of the control group 98.94%(93/94). There was no significant difference between the two groups (χ 2=0.77, P=0.380). The success rate of delivery sheath system was 96.81%(91/94) and 98.94%(93/94) in the trail group and the control group,respectively. There was no significant difference between the two groups( P=0.621). There was 1 case (1.22%) of new asymptomatic pulmonary embolism in the trial group after filter placement and 2 cases (2.44%) in the control group. There was no significant difference between the two groups ( P>0.05). No filter fracture or migration (>20 mm) occurred in either group. The tilting of filter (>15°) was found in 1 case (1.06%) in the test group and 1 case (1.06%) in the control group when the filter was placed. The tilting of filter (>15°) was found in 0 case in the test group and 2 cases (2.44%) in the control group when the filter was retrieved. There was no significant difference between the two groups ( P>0.05). Inferior vena cava thrombosis before filter retrieval was found in 5 cases (5.75%) in trial group and 3 cases (3.30%) in control group. There was no significant difference between the two groups ( P=0.489). There were no immediate serious complications during filter placement/removal in either group. No filter obstruction,migration,deformation,penetration and occlusion of inferior vena cava. The incidence of device-related adverse events was low in both group. There was no significant difference between the two groups ( P>0.05). Conclusion:The home-made umbrella-shaped Octoparms inferior vena cava filter is effective and safe in preventing pulmonary embolism, and is not worse than Celect filter.

BACKGROUND: Circular RNAs (circRNAs) are considered to be important regulators in cancer biology. In this study, we focused on the effect of circRNA baculoviral inhibitor of apoptosis protein (IAP) repeat containing 6 (circBIRC6) on non-small cell lung cancer (NSCLC) progression. METHODS: The NSCLC and adjacent non-tumor tissues were collected at Shanghai Ninth People's Hospital. Quantitative real-time polymerase chain reaction was conducted for assessing the levels of circBIRC6, amyloid beta precursor protein binding protein 2 (APPBP2) messenger RNA (mRNA), baculoviral IAP repeat containing 6 mRNA (BIRC6), and microRNA-217 (miR-217). Western blot assay was adopted for measuring the protein levels of APPBP2, E-cadherin, N-cadherin, and vimentin. Colony formation assay, transwell assay, and flow cytometry analysis were utilized for evaluating cell colony formation, metastasis, and apoptosis. Dualluciferase reporter assay and RNA immunoprecipitation assay were carried out to determine the interaction between miR-217 and circBIRC6 and APPBP2 in NSCLC tissues. The murine xenograft model assay was used to investigate the function of circBIRC6 in tumor formation in vivo. Differences were analyzed via Student's t test or one-way analysis of variance. Pearson's correlation coefficient analysis was used to analyze linear correlation. RESULTS: CircBIRC6 was overexpressed in NSCLC tissues and cells. Knockdown of circBIRC6 repressed the colony formation and metastasis and facilitated apoptosis of NSCLC cells in vitro and restrained tumorigenesis in vivo. Mechanically, circBIRC6 functioned as miR-217 sponge to promote APPBP2 expression in NSCLC cells. MiR-217 inhibition rescued circBIRC6 knockdown-mediated effects on NSCLC cell colony formation, metastasis, and apoptosis. Overexpression of miR-217 inhibited the malignant phenotypes of NSCLC cells, while the effects were abrogated by elevating APPBP2. CONCLUSIONS CircBIRC6 aggravated NSCLC cell progression by elevating APPBP2 via sponging miR-217, which might provide a fresh perspective on NSCLC therapy.

RNA binding protein (RBP) plays a key role in gene regulation and participate in RNA translation, modification, splicing, transport and other important biological processes. Studies have shown that abnormal expression of RBP is associated with a variety of diseases. The Musashi (Msi) family of mammals is an evolutionarily conserved and powerful RBP, whose members Msi1 and Msi2 play important roles in the regulation of stem cell activity and tumor development. The Msi family members regulate a variety of biological processes by binding and regulating mRNA translation, stability and downstream cell signaling pathways, and among them, Msi2 is closely related to embryonic growth and development, maintenance of tumor stem cells and development of hematological tumors. Accumulating evidence has shown that Msi2 also plays a crucial role in the development of solid tumors, mainly by affecting the proliferation, invasion, metastasis and drug resistance of tumors, involving Wnt/β-catenin, TGF-β/SMAD3, Akt/mTOR, JAK/STAT, Numb and their related signaling pathways (Notch, p53, and Hedgehog pathway). Preclinical studies of Msi2 gene as a therapeutic target for tumor have achieved preliminary results. This review summarizes the molecular structure, physiological function, role of Msi2 in the development and progression of various solid tumors and the signaling pathways involved.

Objective:Due to the limitation of traditional identification methods of Chinese medicinal materials， the study established a rapid method to identify Persicae Semen mixed with Armeniacae Semen Amarum by allele-specific polymerase chain reaction （PCR）. Method:By comparing the ribosomal DNA internal transcribed spacer （ITS） gene sequences of Persicae Semen and Armeniacae Semen Amarum， single nucleotide polymorphism （SNP） sites were searched and specific primers were designed. Different Persicae Semen and Armeniacae Semen Amarum samples were amplified by PCR， the effects of annealing temperature， primer concentration and cycle number on the PCR reaction system were optimized， and the specificity and detection limit of this method were investigated. In addition， the established PCR method was used to detect the samples of Persicae Semen mixed with different proportion of Armeniacae Semen Amarum from different sources and producing areas. Result:A specific PCR method for identifying Persicae Semen mixed with Armeniacae Semen Amarum was established. When the annealing temperature was 63 ℃ and the number of primer cycles was 30， only Armeniacae Semen Amarum could be amplified with 432 bp specific band， while Persicae Semen samples did not have this band. The minimum detection limit of this method for Armeniacae Semen Amarum was 0.2 ng， and the detection limit for Armeniacae Semen Amarum adulterated in Persicae Semen was 1%. Conclusion:The established allele-specific PCR method can accurately detect whether there is Armeniacae Semen Amarum in Persicae Semen， which can provide experimental basis for the quality control of Persicae Semen and guarantee the safety of its clinical use.

OBJECTIVE: To explore the mechanism of catgut embedding at back- points on nonalcoholic steatohepatitis (NASH) in rats based on IKK/IKB/NF-κB signaling pathway and downstream inflammatory factors. METHODS: Eighty SPF SD rats were selected, among them 10 rats were selected divided into a normal group (group A), and the remaining 70 rats were fed with high-fat diet to establish NASH model. At the end of 12 weeks, 10 rats were randomly selected to verify whether the model establishment was successful. Then the remaining 60 rats were randomly divided into a model group (group B), a catgut embedding at back- points group (group C), a catgut embedding at abdominal points group (group D), an acupuncture at back- points group (group E), a sham catgut embedding group (group F) and a western medication group (group G), 10 rats in each group. The rats in the group C were treated with catgut embedding at "Ganshu" (BL 18), "Pishu" (BL 20), "Weishu" (BL 21) and "Shenshu" (BL 23); the rats in the group D were treated with catgut embedding at "Daheng" (SP 15), "Fujie" (SP 14), "Huaroumen" (ST 24) and "Tianshu" (ST 25); the rats in the group E were treated with acupuncture at the same acupoints as the group C; the rats in the group F were treated with catgut embedding at back- points but the needle did not enter subcutaneous tissue gamma; the rats in the group G were treated with intragastric administration of vitamin E capsule. All the treatment was given for 4 weeks. The rats in the group A were fed with normal diet until the end of 16 weeks without any intervention. The rats in the group B continued to be fed with high-fat diet until the end of 16 weeks. After the intervention, the liver index was calculated; the liver histomorphology was observed by HE staining; the liver function [alanine aminotransferase (ALT), gamma glutamyl transferase (γ-GGT), alkaline phosphatase (ALP)] and blood lipid [serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL)] were measured by serum biochemistry. The serum levels of TNF-α, IL-6 and IL-1βwere detected by ELISA, and the expressions of IKK-α, NF-κBp65, IL-6, IL-1β and TNF-α proteins in liver tissue were detected by Western blot. The temperature of the conception vessel and the governor vessel was measured by infrared thermography. RESULTS: Compared with the group A, the obvious steatosis and inflammatory cell infiltration were observed in the group B, and the body weight, liver wet-weight and liver index were all increased (<0.01). Compared with the group B, the liver tissue morphology in the group C, the group D, the group E and the group G was improved in varying degrees, and the liver index was decreased (<0.05), which was the most significant in the group C (<0.05). Compared with the group A, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β were all increased in the group B (<0.01); compared with the group B, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β in all intervention groups were all decreased in varying degrees (<0.01, <0.05), which was the most significant in the group C (<0.01). Compare with the group A, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in the group B were all increased (<0.01); compared with the group B, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in all intervention groups were decreased in varying degrees (<0.05), which was the most significant in the group C (<0.01). Compared with the group A, the temperature of the conception vessel and governor vessel was decreased in the group B (<0.01). Compared with the group B, the temperature of the conception vessel and governor vessel was all increased in the group C, the group D and the group E (<0.01); the temperature of the conception vessel in the group C was similar to that in the group D (>0.05), while the temperature of the governor vessel in the group C was superior to that in the group D (<0.05). CONCLUSION The catgut embedding at back- points might inhibit the activation of IKK/IKB/NF-κB signaling pathway to interrupt the inflammatory cascade, and reduce the "second hit" of inflammatory factors on liver, which could slow down NASH progress and prevent and treat NASH.
