With the continuous innovation of genomics,proteomics and molecular biological detection technol-ogy,the treatment of non-small cell lung cancer(NSCLC)has changed from traditional chemotherapy to immunotherapy and targeted therapy.Among them,molecular tumor markers targeting tyrosine kinase pathways play more important roles in clinical practice.For advanced NSCLC patients with positive epidermal growth factor receptor(EGFR)mutations,there are many first-line drugs on the market and they could bring significant efficacy,thus completely subverting the treatment pattern of advanced NSCLC.Common mutations of EGFR in Chinese patients are located on exons 19,20 and 21,of which exons 19 and 21 mutations are the more common types.Besides,there is also a subtype of EGFR mutations,known as EGFR 20 exon insertion(EGFR 20ins)mutation.The authors summarized the treatment of a lung adenocarcinoma patient with EGFR 20ins mutation accepting Furmonertinib mesylate,in order to provide effective references for clinical diagnosis and treatment.

To understand the pathogenicity,virulence genes,drug resistance genes,and drug resistance of Staphylococcus aureus isolated from yaks in some areas of Lhasa and Nagqu City,55 yak nasal swab samples were analyzed for S.aureus in this study.The cocci were isolated and identified,and the carriage of virulence genes and drug resistance genes,as well as the pathogenicity and drug sensitivity of the isolated S.aureus strains,were detected with PCR,artificially infected mice,and the K-B drug susceptibility disk method.Seven strains of S.aureus were isolated from the 55 yak nasal swab samples,with an iso-lation rate of 12.73％.The isolated strains were all pathogenic to mice,with a fatality rate exceeding 60％.These seven strains of S.aureus carried three drug resistance genes(tetM,tet,and mecA)and six virulence genes(seb,sec,clfA,hla,hlb,and nuc).The detection rate of the three drug resistance genes was 100％,whereas the detection rate of the six virulence genes in the isolates ranged from 83.33％to 100％.The resistance rates of the isolated strains to penicillin,ampicillin,and cotrimox-azole reached 85.71％-100％,whereas the resistance rates to tetracycline and ceftazidime were both 28.57％.Thus,yaks in Lhasa and Nagqu cities were found to be infected by S.aureus strains carrying various drug-resistance genes and virulence genes.These strains were highly pathogenic and showed sensi-tivity to most antibacterial drugs.These findings may serve as a reference for treating S.aureus infection in yaks in the cities of Lhasa and Nagqu.

Objective:To investigate the current situation of standardized patient programs and standardized patient educators in China, and to analyze the existing problems in the implementation.Methods:Questionnaire survey was used in this study. The questionnaire was made by Delphi method, and distributed via E-mails or through the internet to medical colleges, affiliated hospitals and general hospitals across the country. Microsoft Office Excel 2016 was used for data reduction and analysis and cartography.Results:A total of 94 medical colleges and hospitals of 27 provinces and municipalities participated in the survey, of which 43.62% had carried out standardized patient programs. The primary factor affecting the program implementation was the lack of standardized patient educators. The existing trainers were mainly clinicians or nurses, and the main way of training the educators was to send them to other universities for learning. A majority of respondents (94.68%) think it is necessary to establish and formulate a unified national certification system for standardized patient educators.Conclusion:The development of standardized patient program is unbalanced in China, and the lack of standardized patient educators has become the primary factor restricting the development. In order to make standardized patients a greater role in medical education, we should encourage different types of personnel to join in the standardized patient training team, to clarify the responsibilities of standardized patient educators, to standardize the process of trainers training, and to establish the certification system of standardized patient educators.

OBJECTIVE: To observe the effect of moxa-cone moxibustion at lung's back- METHODS: Sixty SPF-grade healthy male Balb/c mice were randomly divided into a normal group, a model group, an LY294002 group (LY group), an electroacupuncture (EA) group and a moxibustion group, 12 mice in each group. Asthma model was replicated by using ovalbumin (OVA) sensitization. Except the mice in the normal group, all the mice were intraperitoneally injected with sensitization solution (containing 15 μg of OVA and 30 mg of aluminum hydroxide) on the 1st day, 7th day and 14th day, 0.5 mL per mice; from the 15th day, 1% OVA solution was atomized for 20 min, once a day for 2 weeks; the mice in the normal group was treated with identical operations but with 0.9% sodium chloride solution. The mice in the LY group were treated with injection of LY294002 at tail vein on the 13th day, 14th day and 15th day. At the beginning of the 15th day, The mice in the EA group were treated with EA at "Feishu" (BL 13) and "Zhongfu" (LU 1) with disperse-dense wave, frequency of 2 Hz/20 Hz, intensity of 1 mA, 15 min each time, once a day for 2 weeks. The mice in the moxibustion group was treated with moxa-cone moxibustion at "Feishu" (BL 13) and "Zhongfu" (LU 1) from the 15th day, three moxa-cones per acupoint, once a day for 2 weeks. On the 16th day, 18th day and 22nd day, the incubation period of asthma was recorded. On the 29th day, all the samples were collected. The expressions of IL-17 and IL-10 in serum and bronchoalveolar lavage fluid (BALF) were detected by ELISA method. The pathological changes of lung tissue were observed by HE staining. The percentage of Th17, Treg and Th17/Treg ratio in spleen tissue were detected by flow cytometry method. RESULTS: Compared with the normal group, the incubation period of asthma in the model group was significantly shortened ( CONCLUSION The Th17/Treg is imbalanced in asthmatic body.

Purpose: Circular RNAs (circRNAs) are a new class of RNA molecules whose function is largely unknown. There is a growing evidence that circRNAs play an important regulatory role in the progression of a variety of human cancers. However, the exact roles and the mechanisms of circRNAs in gastric cancer are not clear. In this study, we aimed to elucidate the mechanism of hsa_circ_0005556. Materials and Methods: Real-time quantitative polymerase chain reaction was used to detect the expression of hsa_circ_0005556, miR-4270, and matrix metalloproteinase-19 (MMP19) in gastric cancer tissues and cell lines. The expression of hsa_circ_0005556 in gastric cancer cells was silenced by lentivirus, and cell proliferation, invasion, migration, and tumorigenesis in nude mice were assessed to evaluate the function of hsa_circ_0005556 in gastric cancer. Results: The expression of hsa_circ_0005556 in gastric cancer tissues and gastric cancer cell lines was higher compared to normal controls. In vitro, the downregulation of hsa_ circ_0005556 significantly inhibited proliferation, migration, and invasion of gastric cancer cells. In vivo, the downregulation of hsa_circ_0005556 suppressed tumor growth in nude mice. Conclusions Our study shows that the hsa_circ_0005556/miR-4270/MMP19 axis is involved in proliferation, migration, and invasion of gastric cancer cells through the competing endogenous RNA (ceRNA) mechanism.

Tung tree (Vernicia fordii) is an economically important woody oil plant that produces tung oil rich in eleostearic acid. Here, we report a high-quality chromosome-scale genome sequence of tung tree. The genome sequence was assembled by combining Illumina short reads, Pacific Bio-sciences single-molecule real-time long reads, and Hi-C sequencing data. The size of tung tree gen-ome is 1.12 Gb, with 28,422 predicted genes and over 73％ repeat sequences. The V. fordii underwent an ancient genome triplication event shared by core eudicots but no further whole-genome duplication in the subsequent ca. 34.55 million years of evolutionary history of the tung tree lineage. Insertion time analysis revealed that repeat-driven genome expansion might have arisen as a result of long-standing long terminal repeat retrotransposon bursts and lack of efficient DNA deletion mechanisms. The genome harbors 88 resistance genes encoding nucleotide-binding sites;17 of these genes may be involved in early-infection stage of Fusarium wilt resistance. Further, 651 oil-related genes were identified, 88 of which are predicted to be directly involved in tung oil biosynthesis. Relatively few phosphoenolpyruvate carboxykinase genes, and synergistic effectsbetween transcription factors and oil biosynthesis-related genes might contribute to the high oil content of tung seed. The tung tree genome constitutes a valuable resource for understanding genome evolution, as well as for molecular breeding and genetic improvements for oil production.

BACKGROUNDDendritic cells are professional antigen-presenting cells found in an immature state in epithelia and interstitial space, where they capture antigens such as pathogens or damaged tissue. Matrix metallopeptidase 13 (MMP-13), a member of the collagenase subfamily, is involved in many different cellular processes and is expressed in murine bone marrow-derived dendritic cells (DCs). The function of MMP-13 in DCs is not well understood. Here, we investigated the effect of MMP-13 on DC maturation, apoptosis, and phagocytosis.

METHODSBone marrow-derived dendritic cells were obtained from C57BL/6 mice. One short-interfering RNA specific for MMP-13 was used to transfect DCs. MMP-13-silenced DCs and control DCs were prepared, and apoptosis was measured using real-time polymerase chain reaction and Western blotting. MMP-13-silenced DCs and control DCs were analyzed for surface expression of CD80 and CD86 and phagocytosis capability using flow cytometry.

RESULTSCompared to the control DCs, MMP-13-silenced DCs increased expression of anti-apoptosis-related genes, BAG1 (control group vs. MMP-13-silenced group: 4.08 ± 0.60 vs. 6.11 ± 0.87, P = 0.008), BCL-2 (control group vs. MMP-13-silenced group: 7.54 ± 0.76 vs. 9.54 ± 1.29, P = 0.036), and TP73 (control group vs. MMP-13-silenced group: 4.33 ± 0.29 vs. 5.60 ± 0.32, P = 0.001) and decreased apoptosis-related genes, CASP1 (control group vs. MMP-13-silenced group: 3.79 ± 0.67 vs. 2.54 ± 0.39, P = 0.019), LTBR (control group vs. MMP-13-silenced group: 9.23 ± 1.25 vs. 6.24 ± 1.15, P = 0.012), and CASP4 (control group vs. MMP-13-silenced group: 2.07 ± 0.56 vs. 0.35 ± 0.35, P = 0.002). Protein levels confirmed the same expression pattern. MMP-13-silenced groups decreased expression of CD86 on DCs; however, there was no statistical difference in CD80 surface expression. Furthermore, MMP-13-silenced groups exhibited weaker phagocytosis capability.

CONCLUSIONThese results indicate that MMP-13 inhibition dampens DC maturation, apoptosis, and phagocytosis.
