ABSTRACT

In this study, nrDNA ITS sequences of Lycium cultivars were sequenced and used to test the existence of incomplete concerted evolution and pseudogenes. Together with 44 ITS sequences retrieved from GenBank, the pattern of base substitutions, GC content, 5.8S conserved motifs, the minimum free energy of secondary structures, nucleotide diversity and phylogenetic relationship of the samples were analyzed. While 83 of the 144 sequences were identified as pseudogenes, the results suggested a high degree of polymorphism and putative pseudogenes in Lycium, suggesting an incomplete concerted evolution of the ITS region. ITS polymorphism and pseudogene of Lycium were systematically tested for the first time. This research provides a references for ITS sequence to be used in the study of Lycium germplasm resources and DNA barcode identification.

ABSTRACT

OBJECTIVES@#To observe the effect of type 2 diabetes mellitus (T2DM) on mandibular bone regeneration and the expression of factors related to T helper cell 17 (Th17 cell) and regulatory T cell (Treg cell) in mice.@*METHODS@#Thirty-six 6-week-old C57BL/6J male mice were randomly divided into normal control (NC) and T2DM groups. Fasting blood glucose levels were detected 0 d, 7 d, 14 d, and 28 d after surgery for mandibular defects. Hematoxylin-eosin (HE) staining was used in observing the bone after 7 d, 14 d, and 28 d of the healing process. Immunohistochemical staining was used in observing the expression of alkaline phosphatase (ALP), Runt-related transcription factor 2 (RUNX2), forkhead box protein P3 (Foxp3), retinoic acid related orphan receptor gamma T (RORγt), and protein tyrosine phosphatase non-receptor type 2 (PTPN2) after 7 d, 14 d, and 28 d of healing.@*RESULTS@#HE staining showed that the area with new bones in the T2DM group was significantly smaller than that in the NC group. Immunohistochemical staining showed that the expression of osteogenesis related proteins ALP and RUNX2 were significantly reduced in the T2DM group. In addition, the number of RORγt positive cells increased, whereas the number of Foxp3 positive cells and the expression PTPN2 decreased significantly in the mandibular bone defect in mice with T2DM.@*CONCLUSIONS@#T2DM significantly inhibit mandibular bone regeneration in mice. Decline in PTPN2 expression and the transition of Treg and Th17 may be the underlying molecular mechanisms.

ABSTRACT

The normal development of follicles involves a series of complex life processes such as ordered transcriptional activation and inhibition, which is crucial for female reproductive ability. Histone methylation can change the chromatin state in cells and affect the transcription activity of genes. Current studies indicate that epigenetic modifications such as histone methylation play an important regulatory role in follicular development in female mammals. This paper summarized the relationship between H3K4, H3K9 methylation and germ cell development, their regulatory effects, including their dynamical changes during follicular development, and the progress of H3K4me3 and other histone methylation binding to promoter regions of different genes to regulate gene expression and thus affect germ cell epigenetic reprogramming, oocyte transcription, meiosis and other processes. This review will provide a reference for the study of mechanisms related to histone methylation modification and the development and maturation of gonadal parenchymal cells.

ABSTRACT

Objective@#To explore the status of PM 2.5 pollution in school classrooms and the student exposure level, and to provide basic data to safeguard the health of students.@*Methods@#This study continuously monitored the PM 2.5 levels of 16 naturally ventilated classrooms in eight primary and secondary schools in Jiamusi for one academic year using an online environmental monitoring instrument. At the same time, outdoor PM 2.5 data was captured for comparative research, and student exposure to PM 2.5 during school hours was evaluated.@*Results@#The average concentration of PM 2.5 in the classroom in the spring and autumn semesters was (26.93±24.7) and (31.85±30.37)μg/m 3, respectively, and the indoor/outdoor ratio ( I/O ) was 0.92 and 0.95, respectively, which indicated a strong correlation between them. The daily average concentration of all classrooms during both semesters was ( 28.93 ±26.85)μg/m 3, which was slightly higher than the average concentration of (27.53±26.53)μg/m 3 during the daytime when students were in school. In addition, the concentration on workdays was higher than that observed on weekends, and this was termed the "weekend effect". The indoor PM 2.5 concentration was lower on higher floors. The comprehensive exposure concentration of students during school was 28.48 μg/m 3 in spring semester and 31.87 μg/m 3 in autumn semester.@*Conclusion@#PM 2.5 levels in the classrooms varied according to time, the horizontal space, and the vertical space, and the level of indoor PM 2.5 pollution largely depended on outdoor pollution sources. Differences in PM 2.5 exposure were observed between.

ABSTRACT

OBJECTIVE@#To investigate the mechanism of Tojapride, a Chinese herbal formula extract, on strengthening the barrier function of esophageal epithelium in rats with reflux esophagitis (RE).@*METHODS@#Ten out of 85 SD rats were randomly selected as the sham group (n10), and 75 rats were developed a reflux esophagitis model (RE) by the esophageal and duodenal side-to-side anastomosis. Fifty successful modeling rats were divided into different medicated groups through a random number table including the model, low-, medium-, and high-dose of Tojapride as well as omeprazole groups (n10). Three doses of Tojapride [5.73, 11.46, 22.92 g/(kg•d)] and omeprazole [4.17 mg/(kg•d)] were administrated intragastrically twice daily for 3 weeks. And the rats in the sham and model groups were administered 10 mL/kg distilled water. Gastric fluid was collected and the supernatant was kept to measure for volume, pH value and acidity. Esophageal tissues were isolated to monitor the morphological changes through hematoxylin-eosin (HE) staining, and esophageal epithelial ultrastructure was observed by transmission electron microscopy. The expressions of nuclear factor kappa-light-chain-enhancer of activated B cells p65 (NF-KBp65), κB kinase beta (IKKß), occludin, and zonula occludens-1 (ZO-1) in the esophageal tissues were measured by immunohistochemistry and Western blot, respectively.@*RESULTS@#The gastric pH value in the model group was significantly lower than the sham group (P<0.05). Compared with the model group, gastric pH value in the omeprazole and medium-dose of Tojapride groups were significantly higher (P<0.05). A large area of ulceration was found on the esophageal mucosa from the model rats, while varying degrees of congestion and partially visible erosion was observed in the remaining groups. Remarkable increase in cell gap width and decrease in desmosome count was seen in RE rats and the effect was reversed by Tojapride treatment. Compared with the sham group, the IKKß levels were significantly higher in the model group (P<0.05). However, the IKKß levels were down-regulated after treatment by all doses of Tojapride (P<0.01 or P<0.05). The occluding and ZO-1 levels decreased in the model group compared with the sham group (Ps0.01 or Ps0.05), while both indices were significantly up-regulated in the Tojapride-treated groups (P<0.01 or P<0.05).@*CONCLUSIONS@#Tojapride could improve the pathological conditions of esophageal epithelium in RE rats. The underlying mechanisms may involve in down-regulating the IKKß expression and elevating ZO-1 and occludin expression, thereby alleviating the inflammation of the esophagus and strengthening the barrier function of the esophageal epithelium.

ABSTRACT

Objective: To investigate, with transcriptome sequencing, the mechanism of metabolic memory in epithelial-mensenchymal transition (EMT) of podocytes induced by high glucose. Methods: Mouse glomerular podocytes were cultured in four groups: normal glucose group (NG, 5 mmol/L D-glucose X48 h); high glucose group (HG, 30 mmol/L D-glucose X48 h); metabolic memory group (MG, 30 mmol/L D-glucose x48 h, +5.5 mmol/L D-glouse x48 h); osmotic pressure group (OSM, 5.5 mmol/L D-glucose + 24.5 mmol/L mannitol X48 h). The expressions of Nephrin and α-SMA in podocyte EMT were detected by Western blotting and immunofluorescence. Illumina Hiseq 2000 was applied to characterize the transcriptome profiles of NG, HG and MG groups, DESeq was used to identify the differentially expressed genes (DEGs), gene ontology (GO) enrichment analysis and kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis were implemented for DEGs. The expression levels of the selected DEGs were detected by real-time fluorescence quantitative PCR. Results: Compared with NG group, both Western blotting and immunofluorescence showed that the expression level of Nephrin decreased, while of ct-SMA increased (P0.05). RNA-Seq showed that 194 genes (119 up-regulation and 75 down-regulation) were differentially expressed between HG and NG groups, while 532 genes (316 up-regulation and 216 down-regulation) were differentially expressed between MG and NG groups. Further comparison of the above DEGs showed 108 genes (35 up-regulation and 73 down-regulation) had similar expression patterns in HG and MG groups. The GO enrichment analysis showed 10 GO terms were significantly enriched, and the KEGG pathway enrichment analysis showed TGF-β, focal adhesion plaque, Rap1 and pluripotent regulation of stem cells signal pathways were significantly enriched. PCR showed that the expression levels of Smad9, Snai1 and Mapkapk3 were higher, while of Igf1, Fgf22, Lama1 and Zfhx3 were lower in HG and MG group than in NG group. Conclusions: High glucose can induce podocyte EMT in vitro, and there is a "memory phenomenon" even after normal glucose culture. The occurrence of this phenomenon may be potentially related to TGF-β, focal adhesion plaque, Rap1 and pluripotent regulation of stem cells signal pathways, and upregulation of Smad9, Snai1 and Mapkapk3, as well as downregulation of Igf1, Fgf22, Lama1 and Zfhx3.

ABSTRACT

Thyroid follicular carcinoma (FTC) is one of the highly differentiated malignant tumors second only to papillary thyroid carcinoma (PTC). Its occurrence is mainly caused by the abnormal differentiation of thyroid follicular epithelial cells. Lymph node metastasis around FTC is rare, but distant tissue metastasis is more common. At present, there are few studies on the pathogenesis of FTC. The clinical diagnosis and treatment of FTC are mainly focused on imaging examination, fine needle aspiration and so on. Surgical resection is the main clinical treatment, with unfavourable prognosis. In this paper, the epidemiology, pathogenesis, diagnosis and treatment of FTC were summarized, and the research progress of FTC was reviewed.

ABSTRACT

Objective@#To examine pubertal timing across body mass index (BMI) trajectory under polygenic susceptibility in boys and girls,and to provide a reference basis for children’s adolescent development deviation form early intervention strategies.@*Methods@#All the participants were recruited from 1 to 3 grade in 2016 from 2 Bengbu primary school and were followed up for 3 consecutive years. The study comprised 997 children (418 boys) with available data for height, weight, BMI, breast Tanner stages and testicular volume annually. The polygenic risk score (PRS) was computed based on 17 SNPs derived from published genome-wide association studies for early pubertal timing. Group-based trajectory model (GBTM) was used to identified BMI trajectory in children. Accelerated failure time model (AFT) was used to examine associations of different BMI trajectory and polygenic risk with pubertal development in boys and girls.@*Results@#Classes of BMI trajectory were persistently healthy weight, persistently overweight and persistently obesity. Adjusted concomitant variables, boys with persistently obesity exhibited 6.10-mo delay of testicular volume in low polygenic risk group (adjusted TR=1.05,P=0.04). Compared with the girls in persistently healthy weight group, the girls with low PRS were persistently overweight or obesity, which was associated with thelarche age 3.42 and 6.84-mo earlier, respectively (adjusted TR=0.97,0.94,P<0.01). Persistently overweight or obesity in girls with moderate PRS was associated with an earlier age of thelarche timing of 6.72 and 8.96-mo, respectively (adjusted TR=0.94,0.92, P<0.01). At high PRS groups, the persistently obese girls were found to have a more advanced age (10.80 and 12.96-mo, respectively) of thelarche (adjusted TR=0.90,0.88, P<0.01).@*Conclusion@#Persistently overweight and obesity is associated with early thelarche in girls, but persistently obesity may increase delayed puberty risk in boys with low polygenic risk.

ABSTRACT

Objective@#The study aims to examine the prospective association and sex differences of pubertal timing and tempo with behavior problems.@*Methods@#Participants from two primary schools in grade 1-3 were selected through clustering convenience sampling method in Bengbu, Anhui Province was established since 2013 (T1), with informed consent, 2 084 students were recruited, and follow-up surveys were conducted in 2015 (T2), 2017 (T3) and 2019 (T4) respectively. Demographic information, non-suicidal self-injury (NSSI), suicidal ideation, suicide plan, suicide attempt and externalizing symptoms were collected through questionnaire investigation, and pubertal development in boys and girls were evaluated by secondary sexual development (testicular volume for boys and breast development for girls). At T4, externalizing symptoms were evaluated by MacArthur Health & Behavior Questionnaire-Child (HBQ-C). Using SAS PROC NLMIXED to fit nonlinear growth model to estimate pubertal timimg and tempo. Puberty timing was classified into early, on-time, and delayed groups; and the puberty tempo into fast, average, and slow groups. Multivariable logistic regression model was used to analyze the predictive effects of modeling pubertal timing and tempo on multi-disciplinary behavior problems in adolescence boys and girls.@*Results@#There were 1 909 people with complete baseline and follow-up questionnaires and puberty development information. Reported rates of externalizing symptoms, NSSI, suicidal ideation, suicide plan, suicide attempt and were 13.9% (265), 24.4% (466), 14.2% (271), 4.6% (88) and 2.3% (43) respectively. Logistic regression analysis results show that fast pubertal tempo increases the risk of externalization [OR(95%CI)=2.85(1.53-5.31) and NSSI [OR(95%CI)=2.11(1.22-3.65)] for boys, and the risk of suicide attempt [OR(95%CI)=2.99(1.07-8.35)] for girls. Slow tempo can reduce the risk of suicidal ideation and suicide plan for boys [OR(95%CI)=0.40(0.18-0.87), 0.07(0.01-0.67)], the externalizing symptoms and suicidal ideation for girls [OR(95%CI)=0.33(0.13-0.81),0.38(0.17-0.85)]. Early pubertal timing will increase the risk of suicide plan for boys [OR(95%CI)=3.60(1.04-12.43)], meanwhile late timing can reduce the risk of NSSI in girls [OR(95%CI)=0.39(0.19-0.80)].@*Conclusion@#The tempo of pubertal development may be a useful predictor of adolescent behavioral problems.

ABSTRACT

To compare the differences in apparent diffusion coefficient (ADC) and fractional anisotropy (FA) between brucella spondylitis (BS) groups at different stages before treatment and the normal control group and to evaluate the change trend of ADC value and FA value at different time points before and after treatment. Totally 53 patients suspected of BS by conventional magnetic resonance imaging (MRI) and later confirmed as BS patients by serological tests were enrolled in this study. These patients underwent conventional MRI and diffusion tensor imaging scans,and the ADC value and FA value were measured. Independent sample test was used to compare the ADC value and FA value between the BS group and the control group,the ADC value and FA value between the BS group at each stage. Repeated measurement ANOV was used to compare the ADC values and FA values at different time points before and after treatment. FA imaging showed that the color code of BS was different from that of the normal control group,and the color code of FA imaging showed increased singal. The ADC values of BS in the acute,subacute,and chronic stages [(1.45±0.02)×10 mm /s,(1.35±0.03)×10 mm /s,(1.26±0.05)×10 mm /s,respectively] were significantly higher than those in the control group [(1.06±0.09) ×10 mm /s](=2.538,=0.009;=1.998,=0.032;=1.575,=0.004),and the FA value (0.55±0.02,0.65±0.03,0.71±0.04,respectively) were significantly lower than those of the control group (0.78±0.02) (=2.440,=0.012; =1.847,=0.041;=2.102,=0.003). Repeated measurement analysis showed that there were statistically significant differences in ADC values and FA values at different time points before and after treatment in the acute,subacute,and chronic stages (ADC:=12.100,<0.001;=8.439,=0.005;=9.704,=0.004,respectively;FA:=7.080,=0.002;=6.607;=0.003;=8.868,=0.001,respectively). The ADC values at different time points after treatment were significantly lower than those before treatment or at a previous time point after treatment (=332.14,<0.001),and the FA values were significantly higher than those before treatment or at a previous time point after treatment (=134.26,<0.001). FA color code can intuitively display differences in BS and normal vertebral bodies and show change of color code before and after treatment. Also,the ADC values and FA values can quantitatively reveal differences between BS and normal vertebral body in different time points and quantify BS vertebral lesion changes before and after treatment. In particular,in BS patients who are recovering from treatment,it can quantify microscopic edema. Therefore,diffusion tensor imaging may be useful objective indicator in evaluating the effectiveness of a specific treatment for BS.

ABSTRACT

Objective@#Recent studies have shown the important influence of various micro factors on the general biological activity and function of endothelial cells (ECs). Vascular endothelial growth factor (VEGF) and angiogenin (ANG) are classic micro factors that promote proliferation, differentiation, and migration of ECs. The underlying pathophysiological mechanisms and related pathways of these micro factors remain the focus of current research.@*Data sources@#An extensive search was undertaken in the PubMed database by using keywords including "micro factors" and "endothelial cell." This search covered relevant research articles published between January 1, 2007 and December 31, 2018.@*Study selection@#Original articles, reviews, and other articles were searched and reviewed for content on micro factors of ECs. Results: VEGF and ANG have critical functions in the occurrence, development, and status of the physiological pathology of ECs. Other EC-associated micro factors include interleukin 10, tumor protein P53, nuclear factor kappa B subunit, interleukin 6, and tumor necrosis factor. The results of Gene Ontology analysis revealed that variations were mainly enriched in positive regulation of transcription by the RNA polymerase II promoter, cellular response to lipopolysaccharides, negative regulation of apoptotic processes, external side of the plasma membrane, cytoplasm, extracellular regions, cytokine activity, growth factor activity, and identical protein binding. The results of the Kyoto Encyclopedia of Genes and Genomes analysis revealed that micro factors were predominantly enriched in inflammatory diseases.@*Conclusions@#In summary, the main mediators, factors, or genes associated with ECs include VEGF and ANG. The effect of micro factors on ECs is complex and multifaceted. This review summarizes the correlation between ECs and several micro factors.

ABSTRACT

Objective: To investigate the chemical constituents from Juniperus convallium, as well as their anticomplementary and antioxidant activities. Methods: The constituents were isolated and purified by column chromatography over silica gel, Sephadex LH-20, ODS-C18, and preparative HPLC. Their structures were identified by spectra analysis. The cell hemolysis assay was used to evaluate the anticomplementary activities and the targets through classical and alternative pathways. Also the anti-oxidant activities were tested by DPPH, ABTS and FRAP methods. Results: A total of 17 compounds were obtained from the ethyl acetate extract of J. convallium and identified as amentoflavone (1), cupressuflavone (2), cupressuflavone-4″’-O-β-D-glucosides (3), naringenin-7-O- glycoside (4), apigenin (5), tiliroside (6), quercetin 3-O-β-D-glucoside (7), quercetin-3-O-rhamnoside (8), hypolaetin-7-O-β-D- glucopyranoside (9), isomassonianoside B (10), (+)-isolariciresinol 2a-O-β-D-glucoside (11), (+)-isolarisiresinol 3a-O-β-D-glucopyranoside(12), cryptomeridiol (13), 3β-hydroxysandaracopimeric acid (14), (1R,3R,4aR,4bS,7R,10aR)-7-ethenyl-1,2,3,4,4a,4b,5,6,7,9,10,10a- dodecahydro-3-hydroxy-1,4a,7-trimethyl-1-phenanthrene methanol (15), 4-hydroxy-5-methyl-coumarin (16) and β-sitosterol (17). Compounds 1-15 and 17 showed anticomplementary activities in different degrees (CH50: 0.05-3.99 mmol/L, AP50: 0.58 -19.13 mmol/L). The flavonoids, especially the biflavonoids, are the important anticomplementary constituents in J. convallium. Further analysis of structure-activity relationship showed that phenolic hydroxyl and glycosidic groups influenced their anticomplementary activity. Only the flavonoids (1-3, 5-9) and lignans (10-12) showed different degrees of antioxidant activities due to their hydroxyl groups. Conclusion: All the 17 compounds are isolated from J. convallium for the first time. The flavonoids and lignans are the important anticomplementary and antioxidant constituents in J. convallium with a certain structure-acticity relationship. This study provides a good reference for further research on the pharmacological substance and quality control of J. convallium.

ABSTRACT

@#Congenital nasolacrimal duct obstruction(CNLDO)is one of the most common ocular disorders in infants, and the main feature is a membranous obstruction of the distal end of the nasolacrimal duct. Methods are considered to treat with CNLDO, including lacrimal sac massage, probing, silicone intubation, balloon dacryocystoplasty, and dacryohynostomy. Recently, the combination use of lacrimal endoscopes may increase the success rate of surgery. Because many CNLDOs can resolve spontaneously, there are still some controversies in the timing of surgery and the choice of treatment options. The aim of the review is to provide a reference for the treatment of CNLDO.

ABSTRACT

Objective To investigate the effect of hand robot-assisted training based on motor imagery on upper limb function of stroke patients.Methods From November, 2016 to May, 2018, 55 hemiplegic patients with upper limb dysfunction were randomly assigned to control group (n = 25) and experimental group (n = 30). The control group received routine hand motor training, while the experimental group received hand robot-assisted training, for four weeks. They were assessed with simplified Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Wolf Motor Function Test (WMFT) and Modified Barthel Index (MBI) before treatment (t0), one week of treatment (t1), immediately after treatment (t2) and 2 months after treatment (t3).Results The score of WMFT improved in the experimental group at t1 (P < 0.05), with no significant difference between groups (Z =-0.901, P> 0.05). The scores of FMA, WMFT and MBI improved in both groups at t2 and t3 (P < 0.05), and the scores of FMA and MBI improved more in the experimental group than in the control group (Z>-2.073, t> 2.034, P < 0.05).Conclusion Hand robot-assisted training based on motor imagery can promote recovery of upper limb function in stroke patients more effective than routine hand function training.

ABSTRACT

Objective To understand the distribution of nerve fibers and the types of neural cells in Aspidogaster conchiola. Methods Whole worms were subjected to silver staining, histochemical staining and hematoxylin-eosin (HE) staining, and the nervous systems of the worms were observed. Results There were 3 types of neural cells in the worm head near the cerebral ganglion, including unipolar, bipolar and multipolar neurons, which were divided into 7 types according to the morphology. There was a nerve network on the surface of pharynx and intestinal tract, as well as the reproductive organ, including testis, ovary, lower uterus and penis sac. The nerve network was consisted of circular and longitudinal nerve fibers, and the structure of the nerve network around the mouth was similar to central nerve. Conclusions The structure of the A. conchiola central nervous system is very complicated, and the neural networks may be associated with the physiologic activity of the worm. Different neural cells may have diverse functions.

ABSTRACT

OBJECTIVE@#To compare the serum glycerophospholipid levels in the inflammatory subtypes of asthma by using targeted metabolomic analysis.@*METHODS@#Demographic and clinical data were collected from 51 patients with asthma between January 2015 and December 2015. Routine blood and sputum induction tests were performed. Eosinophilic asthma was defined as induced sputum containing ⪖ 3% eosinophils, and neutrophilic asthma, as induced sputum containing ⪖ 71% neutrophils. Serum metabolic glycerophospholipid profile was determined by liquid chromatography-mass spectrometry. Differences in glycerophospholipid levels between eosinophilic and non-eosinophilic asthma and between neutrophilic and non-neutrophilic asthma were analyzed using partial least squares discriminant analysis.@*RESULTS@#The serum lysophosphatidylglycerol level was significantly higher in the group with ⪖ 3% eosinophils in sputum than in the group with < 3% eosinophils in sputum. The area under the receiver-operating characteristic curve was ⪖ 70%. There was no significant difference in the serum metabolic glycerophospholipid profile between the group with sputum neutrophils ⪖ 71% and the group with sputum neutrophils < 71%.@*CONCLUSION@#Serum lysophosphatidylglycerol is produced abundantly in eosinophilic asthma and may be a biomarker of eosinophilic asthma. This information is helpful for identifying and tailoring treatment for the common asthma subtypes.

ABSTRACT

Polygonatum plants are perennial plants of Liliaceae. There are about 60 species reported at home and abroad,32 species in China,mainly distributed in the north temperate zone. Their main chemical components are steroidal saponins,polysaccharides,flavonoids,alkaloids,etc. They have anti-aging,anti-tumor,immunomodulation,antibacterial,antiviral,hypoglycemic and blood lipid effects. With the development of health industry,Polygonati Rhizome used as medicine and food has attracted great attention in recent years,and has become a research hotspot. However,the material basis of its efficacy is unclear and the product quality is uneven,which seriously limited the rapid upgrading of the industry. This review summarizes Polygonatum plants system classification,the chemical composition and pharmacological activity to provide theoretical basis for the development and utilization of Polygonatum plants.
