"Tangjie" leaves of cultivated Qinan agarwood were used to obtain the complete chloroplast genome using high-throughput sequencing technology. Combined with 12 chloroplast genomes of Aquilaria species downloaded from NCBI, bioinformatics method was employed to determine the chloroplast genome characteristics and phylogenetic relationships. The results showed that the chloroplast genome sequence length of cultivated Qinan agarwood "Tangjie" leaves was 174 909 bp with a GC content of 36.7%. A total of 136 genes were annotated, including 90 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Sequence repeat analysis detected 80 simple sequence repeats(SSRs) and 124 long sequence repeats, with most SSRs composed of A and T bases. Codon preference analysis revealed that AUU was the most frequently used codon, and codons with A and U endings were preferred. Comparative analysis of Aquilaria chloroplast genomes showed relative conservation of the IR region boundaries and identified five highly variable regions: trnD-trnY, trnT-trnL, trnF-ndhJ, petA-cemA, and rpl32, which could serve as potential DNA barcodes specific to the Aquilaria genus. Selection pressure analysis indicated positive selection in the rbcL, rps11, and rpl32 genes. Phylogenetic analysis revealed that cultivated Qinan agarwood "Tangjie" and Aquilaria agallocha clustered together(100% support), supporting the Chinese origin of Qinan agarwood from Aquilaria agallocha. The chloroplast genome data obtained in this study provide a foundation for studying the genetic diversity of cultivated Qinan agarwood and molecular identification of the Aquilaria genus.

Objective: To investigate the clinical and pathologic features, diagnosis and differential diagnosis of congenital hemangioma (CH). Methods: Forty cases of CH were diagnosed from January 2017 to December 2020 in Henan Provincial People's Hospital. The clinical and pathological and immunohistochemical data were analyzed, with review of literature. Results: There were 24 male and 16 female patients. The lesions were located in the head, neck (11 cases), limbs (14 cases), and trunk (15 cases). The clinical manifestations were congenital painless plaques or masses, the larger ones protruded on the skin surface, mostly dusky purple or bright red, with surrounding white halos. Under low magnification, the tumor was lobular and well demarcated, composed of neo-microvascular lumen of different sizes. The vascular endothelial cells were cuboidal or hobnail in appearance, forming stellar drainage vessels within the lobules. Extra-medullary hematopoiesis was seen in one case of rapidly involuting CH; there were different number of tortuous and dilated vascular lumen between the lobular structures, and some non-involuting CH cases were vascular malformations, which were devoid of lobulated structures. Immunohistochemistry showed that endothelial cells were strongly positive for CD31, CD34 and ERG, while D2-40 and GLUT-1 were negative. Conclusions: CH is a benign congenital vascular tumor with characteristic lobulated growth and abnormal blood vessels in the stroma. Pathological diagnosis often needs to be differentiated from infantile hemangioma, pyogenic granuloma, kaposiform hemangioendothelioma and vascular malformation.

BACKGROUND@#Non-coding RNAs have attracted considerable attention for their vital role in cancer. The purpose of this study was to determine the effects of non-coding RNAs on hepatocellular carcinoma (HCC) and reveal their regulatory mechanism in the pathophysiological process.@*METHODS@#We measured the expression of mucin 1 (MUC1) and miR-485-5p in tissues from 15 HCC patients and in liver cancer cell lines by quantitative real-time polymerase chain reaction and Western blot, screened for aberrantly expressed microRNAs (miRNAs) by miRNA microarrays. Bioinformatics tools were used to find the miRNA and circular RNA that regulated MUC1, which were validated by RNA immunoprecipitation assay and luciferase reporter assay. Cell counting kit-8, Transwell assays, and flow cytometry were used to conduct functional experiments. Proteins were examined by western blot and immunohistochemical staining assays. Significant differences between groups were estimated using the one-way analysis of variance. A P < 0.05 was considered statistically significant.@*RESULTS@#MUC1 was overexpressed in HCC tissues compared with that in paratumor tissues (normal vs. tumor, 1.007 ± 0.215 vs. 75.213 ± 18.403, t = 18.401, P < 0.001) while miR-485-5p was down-regulated (normal vs. tumor, 4.894 ± 0.684 vs. 1.586 ± 0.398, t = 16.191, P < 0.001). Inhibition of miR-485-5p promoted cell proliferation (73.33% ± 5.13% vs. 41.33% ± 3.51%, t = 8.913, P < 0.001), migration (102 ± 8 cells vs. 46 ± 8 cells, t = 8.681, P < 0.001), invasion (59 ± 7 cells vs. 28 ± 2 cells, t = 8.034, P < 0.01), and suppressed apoptosis (22.64% ± 6.97% vs. 36.33% ± 3.96%, t = 2.958, P < 0.05) of HepG2 cells with which MUC1 is knocked down. Mechanically, miR-485-5p binds to MUC1, while circHECTD1 binds to miR-485-5p, resulting in the indirect up-regulation of the MUC1 level.@*CONCLUSIONS@#Our findings reveal that circHECTD1 facilitates HCC progression by sponging miR-485-5p to up-regulate MUC1.

Objective:To explore the effects of deleted in lung and esophageal cancer 1 (DLEC1) on osteosarcoma cells and the underlying mechanism.Methods:Immunohistochemical staining for DLEC1 was scored in sixteen paired osteosarcoma tissues and adjacent normal tissues obtained. The present study was conducted on human osteosarcoma 143B cells which were randomly divided into two groups, pDC316-DLEC1 transfection group and pDC316-Null transfection group. Differences in the proportion of EdU-positive cells, cell cycle distribution, proportion of apoptosis cells, number of migrating and invasive cells, expression of epithelial-mesenchymal transformation (EMT) markers (E-cadherin and vimentin), relative protein expression levels of NF-κB, AKT and ERK signaling pathways were assessed between the pDC316-DLEC1 and pDC316-Null transfection groups in in vitro study. The subcutaneous inoculation model and tail vein injection model were developed to evaluate the differences in subcutaneous tumor volume, subcutaneous tumor weight and pulmonary tumor nodules between the above two groups in in vivo study.Results:The DLEC1 immunostaining scores for osteosarcoma tissues and adjacent normal tissues were 2.88±1.15 and 4.25±1.06, respectively. The proportions of EdU-positive cells (36.47%±1.90% vs 51.47%±2.89%) and S phase cells (33.31%±0.61 vs 43.77%±1.47%) were decreased, while G0/G1 phase cells (46.87%±0.73% vs 35.47%±1.14%) and apoptotic cells (13.83%±1.01% vs 3.30%±0.26%) were increased in the pDC316-DLEC1 transfection group compared to those in the pDC316-Null transfection group. Decreased number of migrating cells (199.00±12.53 vs 369.67±10.02) and invasive cells (104.67±9.07 vs 299.67±12.06) and relative expression of vimentin mRNA (0.59±0.02 vs 1.00±0.02) and protein (0.54±0.08 vs 1.00±0.00) were observed in the pDC316-DLEC1 transfection group, while relative expression of E-cadherin mRNA (2.40±0.05 vs 1.00±0.02) and protein(1.98±0.10 vs 1.00±0.00) in the pDC316-DLEC1 transfection group were higher than those in the pDC316-Null transfection group. The relative protein expression of NF-κB (p65), p-AKT (Ser473) and p-ERK (Thr202/Tyr204) in the pDC316-DLEC1 transfection group were decreased by 51.67%±4.04%, 64.67%±5.51% and 48.67%±4.73% compared to those in the pDC316-Null transfection group. In in vivo study, 143B cells in the pDC316-DLEC1 transfection group formed smaller (320.00±145.22 mm 3vs 798.00±221.94 mm 3) and lighter (0.49±0.17 g vs 0.88±0.14 g) subcutaneous tumors and less metastatic lung nodules (7.71±1.80 vs 20.86±3.53) compared with those in the pDC316-Null transfection group. Conclusion:Overexpression of DLEC1 could suppress the NF-κB/AKT/ERK signaling pathways in 143B cells, which further induces G0/G1 arrest and apoptosis that ultimately inhibits cell proliferation and reduces the metastatic potential through reversing EMT.

Objective:To prepare PEG-SH modified GNPs/miR-29 nanoparticles and to investigate the proliferation and differentiation of neural stem cells induced by PEG-SH modified GNPs/miR-29 nanoparticles.Methods:PEG-SH modified GNPs/miR-29 nanoparticles were developed by oxidation-reduction method and were tested for UV absorption spectrum, particle size distribution and zeta potential of nanoparticles. A total of 15 adult male Sprague Dawley (SD) rats were used to establish spinal cord injury model by modified Allen method. The artificial miR-29 and PEG-SH modified GNPs/miR-29 nanoparticles were implanted into the injury site of spinal cord respectively. The stability of miR-29 expression was analyzed by gel electrophoresis. The neural stem cells were isolated and cultured from 10 SPF grade neonatal rats. It was identified by Nestin, GFAP and NSE antibodies. The activity and proliferation of neural stem cells in synthetic miR-29, PEG-SH GNPs and PEG-SH GNPs/miR-29 nanoparticles group was detected by CCK-8 assay. Neural stem cells were cultured with synthetic miR-29, PEG-SH GNPs and PEG-SH GNPs/miR-29 nanoparticles for 1 week. The density, length and number of neuritis were investigated.Results:The solution of PEG-SH modified GNPs showed a brownish red appearance. The spheres were in uniform distribution under transmission electron microscope. The results of UV absorption spectrum showed a single peak wave. The peak value of UV absorption was near 523 nm. The zeta potential increased gradually with the increased content of PEG-SH. The peak value of zeta potential was 22.5±5.2 mV. With the increase of content of PEG, the particle size of PEG-SH modified GNPs rapidly reached peak value at the early stage and then decreased rapidly to a relatively stable level. The synthetic miR-29 and PEG-SH modified GNPs/miR-29 nanoparticles were implanted into the injury site of spinal cord. At 0-6 h, clear band was observed in the synthetic miR-29 group. However, the band was disappeared rapidly at 12-24 h. In PEG-SH GNPs/miR-29 group, clear band were always observed. The OD values of miR-29 group were 0.34±0.17, 0.78±0.31, 1.28±0.68, 1.64±0.38 at 1, 3, 5 and 7 d after inoculation respectively. There was no significant difference in OD values compared with DMEM group. There was no significant difference in OD values among GNPs, PEG-SH GNPs, PEG-SH GNPs/miR-29 and DMEM group. The density (56.38±3.65 μm 2), length (78.25±3.72 μm) and the number [(356±34.52) /1,000×high power field] of neurites in PEG-SH GNPs/miR-29 group were higher than those in miR-29 group, PEG-SH modified GNPs group and saline group. However, there was no significant difference in the density, length and number of neurite between PEG-SH GNPs/miR-29 and serum group. Conclusion:PEG-SH modified GNPs/miR-29 nanoparticless have good biological properties. It can induce the proliferation and differentiation of neural stem cells with protective effects on miR-29.

The theory of " treating same syndrome with different methods" has been widely used in traditional Chinese medicine( TCM). It originated from Treatise on Febrile and Miscellaneous Diseases,and had objective formation factors. The " syndrome" in TCM was a comprehensive manifestation of etiology,characteristics,disease location and trend of disease. Considering the rich connotation of " syndrome",the diverse treatment methods,and the complex ingredients in prescriptions,different specific methods or prescriptions have been often applied to treat the same syndrome. Therefore,based on the theory of " treating same syndrome with different methods",the concept of " prescriptions corresponding to syndromes" was extended,suggesting one syndrome treated with several different prescriptions. Moreover,the concept of " prescription corresponding to syndrome" doesn't refer to a random match between the " syndrome" and the " prescription". Instead,it would refine and objectify the " same syndrome" and seek subtle differences in symptoms,signs and chemical indicators of different diseases and individuals. It further embodied the new diagnosis and treatment model of " pathogenesis combined with pathology,drug properties combined with pharmacology". As a result,the nature of " treating same syndrome with different methods" lies in different microscopic pathological changes or trends,which traditionally expressed as the same syndrome with different symptoms,the same syndrome with different trends,and the same syndrome with different diseases and the same syndrome with different physiques. Therefore,by enriching the connotation of " syndrome",and further defining its objective pathology and development trend,the correspondence between " syndrome" and " prescription" became more precise. By carefully identifying the different characterizations,trends and prognosis in same syndrome,medical practitioners could give individual and dynamic prescriptions,so as to improve the clinical efficacy.

This article reports the clinical features and C12orf65 gene mutations of a girl with autosomal recessive spastic paraplegia-55. The 8-year-old girl experienced disease onset at the age of 5 years and had optic atrophy as the main clinical manifestation, with slow movements in standing up and a slight duck-shaped gait. Peripheral blood DNA samples were collected from this child and her parents and brother to perform high-throughput whole-exome sequencing and high-throughput mitochondrial genome sequencing. Sanger sequencing was performed for verification. The results showed two compound heterozygous mutations, c.394C>T and c.447_449delGGAinsGT, in the C12orf65 gene. The former mutation came from her father and was a known pathogenic mutation, and the latter came from her mother and was a novel mutation which had not been reported in literature. This study expands the mutation spectrum of the C12orf65 gene and thus provides a molecular basis for the etiological diagnosis of the child and the genetic counseling of the family.

<p><b>OBJECTIVE</b>To determine whether B lymphocyte-specific transcription factor Pax5 regulates B-lympho-magenesis without direct binding to promoter.</p><p><b>METHODS</b>Mouse B-lymphoma cell line myc3 and 38B9 were infected with GFPtagged retrovirus that encodes wide type or various mutant pax5 genes. After viral infection for 48 hours, the percentage of GFP positive lymphoma cells was determined by flow cytomety. The percentage of GFP positive tumor cells was further monitored every 3 days in vitro or once the tumor was formed in vivo. Both cell cycle and apoptic cell number of GFP positive lymphoma cells were analyzed using flow cytometry.</p><p><b>RESULTS</b>Similar to the infection with wild type Pax5 retrovirus, infection with Pax5 mt 1-357 and Pax5 mt 304-358 that lacks of DNA binding motif can strongly increase the percentage of GFPB-lymphoma cells both in vitro and in vivo (P<0.01), while infection with empty viral vector migR-GFP and Pax5 mt 1-143 containing only DNA binding motif failed to increase the percentage of GFP positive tumor cells (P>0.05). Moreover, the analysis of flow cytometry demonstrated that more B-lymphoma cells infected with wild type Pax5, Pax5 mt 1-357 and Pax5 mt 304-358 retroviruses entered S and G/M phases in comparison with those infected with empty viral vector migR-GFP and Pax5 mt 1-143. Apoptotic rates among different groups were not significantly changed.</p><p><b>CONCLUSION</b>Pax5 can promote B-lymphoma cell growth both in vitro and in vivo in a promoter-independent manner. This is mainly due to the accelerating of cell cycle rather than decreasing apoptosis. Our studies provide potential theory for restraing B-lymphomagenesis by targeting the specific Pax5 domains.</p>

BACKGROUND/OBJECTIVES: Consumption of pine nut oil (PNO) was shown to reduce weight gain and attenuate hepatic steatosis in mice fed a high-fat diet (HFD). The aim of this study was to examine the effects of PNO on both intestinal and hepatic lipid metabolism in mice fed control or HFD. MATERIALS/METHODS: Five-week-old C57BL/6 mice were fed control diets containing 10% energy fat from either Soybean Oil (SBO) or PNO, or HFD containing 15% energy fat from lard and 30% energy fat from SBO or PNO for 12 weeks. Expression of genes related to intestinal fatty acid (FA) uptake and channeling (Cd36, Fatp4, Acsl5, Acbp), intestinal chylomicron synthesis (Mtp, ApoB48, ApoA4), hepatic lipid uptake and channeling (Lrp1, Fatp5, Acsl1, Acbp), hepatic triacylglycerol (TAG) lipolysis and FA oxidation (Atgl, Cpt1a, Acadl, Ehhadh, Acaa1), as well as very low-density lipoprotein (VLDL) assembly (ApoB100) were determined by real-time PCR. RESULTS: In intestine, significantly lower Cd36 mRNA expression (P < 0.05) and a tendency of lower ApoA4 mRNA levels (P = 0.07) was observed in PNO-fed mice, indicating that PNO consumption may decrease intestinal FA uptake and chylomicron assembly. PNO consumption tended to result in higher hepatic mRNA levels of Atgl (P = 0.08) and Cpt1a (P = 0.05). Significantly higher hepatic mRNA levels of Acadl and ApoB100 were detected in mice fed PNO diet (P < 0.05). These results suggest that PNO could increase hepatic TAG metabolism; mitochondrial fatty acid oxidation and VLDL assembly. CONCLUSIONS: PNO replacement in the diet might function in prevention of excessive lipid uptake by intestine and improve hepatic lipid metabolism in both control diet and HFD fed mice.

Objective To investigate the inhibitory effect of ibuprofen on proliferation and migration of non-small cell lung cancer (NSCLC) cell line NCI-H460 and breast cancer cell line SKBR3, and to discuss the possible mechanism. Methods MTT method was used to detect the proliferation inhibition of the two cancer cell lines after ibuprofen treatment for 24, 48, and 72 h; and Transwell assay was used to study the cell migration in vitro. Real-time PGR and Western blotting analysis were used to detect the mRNA and protein expression of survivin and E-cadherin after ibuprofen treatment. Results MTT assay showed that ibuprofen treatment decreased cell growth in the two cell lines in a dose-dependent manner. Ibuprofen treatment (2 mmol/L, 12 h) significantly inhibited the cell metastasis in the two cell lines. Moreover, real-time PCR and Western blotting analysis showed that ibuprofen treatment caused a reduction in survivin expression and elevation in E-cadherin expression at both mRNA and protein levels. Conclusion Ibuprofen can significantly inhibit human NSCLC proliferation and metastasis in vitro, which might be related to degreased expression of survivin and increased expression of E-cadherin.
