ABSTRACT

ObjectiveTo explore the pretreatment methods to promote the enzymatic digestion and extraction of active ingredients from Magnoliae Officinalis Cortex dregs(MOCD), and to provide a reference basis for the utilization of resource components in MOCD. MethodLiquid chromatography-mass spectrometry(LC-MS) was used for qualitative analysis of resource components in MOCD with an Agilent C18 reversed-phase column(3.0 mm×100 mm, 2.7 µm) at the flow rate of 0.4 mL·min-1, the mobile phase was water(A)-acetonitrile(B) for gradient elution(0-3 min, 25%-48%B; 3-6 min, 48%-59%B; 6-10 min, 59%-80%B; 10-20 min, 80%-90%B; 20-25 min, 90%B), electrospray ionization(ESI) was employed with negative ion mode scanning and scanning range of m/z 50-1 200. A high performance liquid chromatography(HPLC), which refered to the determination in the 2020 edition of Chinese Pharmacopoeia, was used for quantitative analysis of resource components in MOCD. Four kinds of pretreatment agents were used to separate the resource components from MOCD, and the mechanism of different pretreatment agents was investigated by field emission scanning electron microscopy(FESEM), X-ray powder diffraction(XRD) and Fourier transform infrared spectroscopy(FT-IR). ResultMagnolol, honokiol and lignocellulose were identified as the main resource components of MOCD by qualitative and quantitative analysis. Under the conditions of 1% NaOH, reaction temperature at 80 ℃ and reaction time of 60 min, the concentration of reducing sugar produced by the enzymatic hydrolysis was 32.18 g·L-1, which was 79.8% higher than that of the untreated MOCD. After adding tween-80, the enzymatic hydrolysis time was reduced to 1/3 of the original time, the concentration of reducing sugar was increased by 102.0%. And the total recovery of magnolol and honokiol in the pretreatment solution was 69.23%. ConclusionMagnolol, honokiol and lignocellulosic components in MOCD are valuable for development and utilization, the combination of alkaline pretreatment and tween-80 can realize the recovery and utilization of these three resource components, which can provide a new idea for comprehensive utilization of resource components in MOCD.

ABSTRACT

Objective:To observe multiple locus variable-number tandem repeat analysis (MLVA) typing of Brucella isolated from Himalayan marmot in Qinghai-Tibet Plateau of Qinghai Province, and to explore the relationship between the strains and strains previous isolated from Qinghai Province. Methods:Blood samples of Himalayan marmot were collected in Qinghai-Tibet Plateau of Qinghai Province from March 2019 to October 2020. Pathogens were isolated and cultured from Brucella antibody positive samples identified by using the rose bengal test (RBT). Conventional biological methods and molecular biological methods (BCSP31-PCR and AMOS-PCR) were used for strain identification. At the same time, MLVA method was used to genotype the isolated strains, and cluster analysis was used to analyze the genetic relationships between the strains based on the genotype of 70 Brucella isolated from different hosts in Qinghai Province. Results:A total of 1 466 blood samples of Himalayan marmot were collected from Qinghai-Tibet Plateau. Two strains of Brucella were isolated and cultured from 64 RBT-positive samples, named QH2013054 and QH2013062, respectively. They were identified as Brucella ovis biotype Ⅲ by conventional and molecular biological methods. The MLVA genotyping results showed that QH2013054 and QH2013062 were different at the Bru16 locus, indicating different MLVA genotypes. Cluster analysis showed that strain QH2013054 had the same MLVA genotype as 7 strains, among which 6 strains were from 3 farmers and 3 sheep from the same family in Gonghe County, and 1 strain was from a farmer in Menyuan Hui Autonomous County. The strain QH2013062 had the same MLVA genotype as 4 strains, including 3 strains from 3 farmers in Menyuan Hui Autonomous County and 1 strain from a farmer in Tu Autonomous County of Huzhu. Conclusions:The strains of Brucella isolated from Himalayan marmot in Qinghai-Tibet Plateau of Qinghai Province have the same MLVA genotype as some strains of Brucella isolated from humans and sheep in Qinghai Province. It is speculated that the host humans, sheep and Himalayan marmot in Qinghai-Tibet Plateau may have a common source of infection.

ABSTRACT

The mucosal surfaces of the human body are typically colonized by polymicrobial communities, they exist in the gastrointestinal tract, skin, oral cavity, and genitourinary tract, as well as in anatomical sites previously considered sterile, including the lung. These communities interact with the mucosal immune system to maintain homeostasis in health, emphasizing the important role of " second genome" , which is very important to human health. The human lower respiratory tract also harbor many microbes, the imbalance of microbiome composition maybe critically related with many lung disease. Up to date, researches on microbiome of lung caner is still on the first step. Our review mainly describes the characteristic composition of lung microbiome, and the relationship with diseases, especially with lung cancer. We attempts to provide the basis information for further researches about the relationship between human lung microbiome and lung cancer.

ABSTRACT

Objective:To investigate the role of IL-1β in regulating human placenta-derived mesenchymal stem cells (hPMSCs) to induce the differentiation of activated peripheral blood mononuclear cells (PBMCs) into CD8 + IL-10 + T cell subset in patients with rheumatoid arthritis (RA). Methods:Serum IL-1β levels in RA patients were detected by CBA kit. hPMSCs were isolated from healthy subjects by enzyme digestion. PBMCs that were isolated from RA patients and healthy subjects by Ficoll density gradient centrifugation were activated with PHA and CD3/CD28 monoclonal antibody (McAb) and then co-cultured with hPMSCs. Flow cytometry (FCM) was used to analyze the ability of hPMSCs to induce the differentiation of activated PBMCs into CD8 + IL-10 + T cell subset with the presence of programmed death ligand 1 (PD-L1) and/or PD-L2 McAb and IL-1β. Expression of PD-L1 and PD-L2 on hPMSCs under IL-1β stimulation was analyzed by RT-PCR and FCM. Results:Serum IL-1β levels were significantly higher in RA patients than in healthy subjects. After the activation by PHA and CD3/CD28 McAb, the proportion of CD8 + IL-10 + T cells in PBMCs of RA patients was significantly lower than that of healthy subjects. Moreover, the proportion of CD8 + IL-10 + T cells significantly increased after co-cultured with hPMSCs. The ability of IL-1β-treated hPMSCs to induce activated PBMCs to differentiate into CD8 + IL-10 + T cells was significantly enhanced compared to untreated hPMSCs. IL-1β could up-regulate the expression of PD-L1 and PD-L2 on hPMSCs. Blocking the expression of PD-L1 and/or PD-L2 on hPMSCs significantly reduced the ability of hPMSCs to induce activated PBMCs to differentiate into CD8 + IL-10 + T cells. Conclusions:IL-1β enhanced the capacity of hPMSCs to induce activated PBMCs to differentiate into CD8 + IL-10 + T cells in RA patients by up-regulating the expression of PD-L1 and PD-L2.

ABSTRACT

Objective To compare the size of the internal target volume (ITV),biological target volume (BTV) and internal biological target volume (IBTV) based on PET-CT and 4DCT for primary nonsmall cell lung cancer (NSCLC),as well as try to apply IBTV in radiotherapy planning.Methods A total of 15 patients with NSCLC were sequentially scanned by an axial enhanced 3DCT,4DCT and 18F-FDG PET-CT in the thoracic region.The gross target volumes (GTVs) of ten phases of 4DCT images were contoured,and ITV was obtained by fusion of ten GTVs.BTV based on PET-CT images was determined by the SUV 2.0.The IBTV was defined by fusion of ITV and BTV.Planning target volumes (PTVs) based on ITV,BTV,and IBTV (PITV,PBTV,PIBTV) were obtained by ITV,BTV and IBTV with a 10-mm expansion respectively.The metrics of PIBTV,PITV and PBTV were compared,and the planning parameters of target volumes and risk organs were evaluated.Results There was no significant difference between ITV and BTV,but there was significant difference between IBTV and ITV and BTV (F=22.533,P < 0.05).To include more than 95% volume of IBTV,it is necessary to expand the margin of 9.0(6.0,12.0)mm based on BTV or 10.00(7.0,12.0)mm based on ITV.There was no significant difference between the two groups (P > 0.05).Dice's similarity coefficient of BTV and ITV was 0.72(0.54,0.79).The intensity modulated radiotherapy plan based on PBTV can guarantee 85.6% (80.5%,91.2%) of PITV to reach the prescription dose,compared with 80.2% (74.4%,87.6%) of PBTV by the plan from PITV.Additionally,the conformity index and homogeneity index were not ideal.The dosimetric parameters of PITV and PBTV in the PIBTV plan were much better than those in PBTV-and PITV plan.Conclusions The radiotherapy plan based on PET-CT or 4DCT could not guarantee a reasonable dose distribution of PTV expanded from ITV or BTV.Thus,using IBTV for radiotherapy is advised.

ABSTRACT

Objective To reconstruct the original three-dimensional conformation of tumor resection tissue through the study of breast-conserving surgery excision specimens for part-mount sub-serial section and pathological three-dimensional (3D) reconstruction,to establish a new margin assessment model,and to guide tumor bed delineation individually for radiotherapy.Methods From February 2016 to February 2017,thirtythree eligible breast cancer patients underwent breast-conserving surgery in Breast Cancer Center of Shandong Cancer Hospital were recruited.The excision specimens were prepared with part-mount sub-serial section,and residual tumors were microscopically outlined,scanned and registered by Photoshop software.The 3D model of residual tumors was reconstructed with 3D-DOCTOR software to evaluate margin status and record pathological type,tumor length and 3D negative margin distance.The gross tumor volume (GTV) was delineated based on clips placed in the lumpectomy cavity.CTV1 and CTV2 were defined by adding uniform 1.00 cm and 1.50 cm margin based on GTV respectively.CTV3 and CTV4 were defined by adding 1.00 cm and 1.50 cm margin based on 3D boundary of excision tumor respectively,and compared the volume differences of CTV1 and CTV3,CTV2 and CTV4.Results Based on the marginal assessment results of 3D pathological reconstruction,the rates of false negatives during the intraoperative rapid pathological examination and postoperative routine pathological margin evaluation were 6.7% (2/30) and 3.4% (1/29) respectively.The pathological type of pathological large slice and routine pathological examination was consistent with rate of 93.9% (31/33).The M(QR) tumor lengths of routine pathological and pathological 3D reconstruction were 1.90 (1.50-2.40) cm and 2.00 (1.60-2.70) cm respectively,with statistical difference between the two groups (Z =-2.438,P =0.015).The M(QR) volumes for CTV1,CTV2,CTV3,CTV4 were 70.76 (49.84-78.07)cm3,110.11 (83.38-126.17) cm3,23.85 (16.46-31.49)cm3 and 38.74 (30.47-50.58) cm3 respectively.There were statistical differences between CTV1 and CTV3,CTV2 and CTV4 (Z =-4.372,P <0.001;Z =-4.372,P <0.001).Conclusion The application of pathological 3D reconstruction technology can largely compensate for the shortcomings of the traditional margin assessment model,make the decisions of adjuvant treatment after breast-conserving surgery more accurate,and guide the tumor bed delineation individually for radiotherapy.

ABSTRACT

Objective In order to explore the association between complement C3 and primary open angle glaucoma (POAG),the serum complement C3 level was detected and the polymorphism of the C3 exon gene was analyzed in patients with POAG.Methods A prospective case-control study was designed.A total of 45 patients with POAG visiting Eye &ENT hospital of Fudan University were collected from December 2014 to December 2015,and 45 age-/gender-matched healthy subjects from yearly health screening were collected as normal controls.Serum C3 concentration was detected by immunoturbidimetric assay.Meanwhile,genomic DNA was extracted from peripheral blood leukocytes,and sequencing for C3 exons was followed with PCR to analyze the gene polymorphism.Statistical analysis was performed by use of SPSS 20.0 software.Student's t test was used to evaluate the difference of serum C3 level between two groups.Chisquare test was used to analyze the difference in the distribution of C3 exon gene polymorphism between two groups.The one-way ANOVA was utilized to analyze the difference of serum C3 level among different genotypes of C3 exon.Results The serum level of C3 in POAG (104.81 ± 29.15)mg/dl was significantly lower (t =-3.162,P =0.002) compared to controls (121.06 ± 18.39) mg/dl.There were a total of seven single nucleotide polymorphisms (SNPs) (rs2230201,rs2230204,rs2230205,rs428453,rs423490rs7951,rs539822147) within the C3 exon gene region,but no mutation was detected.There was no difference in the frequency and distribution of these SNPs between POAG and controls,as well as,there was also no significant difference in serum C3 level among these SNPs genotypes.Conclusions Decreased serum C3 level in POAG patients indicated that complement C3 might be involved in the pathomechanism of glaucoma.No significant abnormality of C3 exon gene was detected,so the gene polymorphism having an impact on serum C3 level could be excluded as a reason probably.

ABSTRACT

Objective To compare the geometric differences of gross tumor volumes(GTV)and displacements of selected clips propagated by rigid image registration(RIR)and deformable image registration (DIR)at end-inhale phase(CT0)and end-exhale phase(CT50)based on four-dimensional computed tomography(4DCT)of the whole breast after breast-conserving surgery(BCS). Methods Forty-four patients who underwent 4DCT simulation scans after BCS were selected. The GTV and displacements of selected metal clips at CT0and CT50were manually delineated by the same radiotherapy physician. Subsequently,the GTV and displacements of selected clips from CT0images were transformed and propagated to CT50images using RIR and DIR.The geometric differences of GTV and displacements of surgical clips from DIR were compared with those from RIR based on the dice similarity coefficient(DSC)and the displacements of the center of mass(COM)in the three-dimensional(3D)directions. Results The mean DSC was 0.86± 0.04 for RIR and 0.87± 0.04 for DIR(P=0.000).The displacements of COM in 3D directions from RIR were significantly greater than those from DIR(1.22 mm vs. 1.10 mm,P=0.000).In the anterior-posterior direction,the displacements from RIR were significantly greater than those from DIR for both GTV and selected clips(P=0.000).However,in the left-right and superior-inferior directions,there were no significant differences in displacements between RIR and DIR for both GTV and the selected clips(all P>0.05). Conclusions DIR can improve the overlap for GTV registration from 4DCT scans at CT0and CT50.Furthermore,DIR is superior to RIR in reflecting GTV and the displacements of selected clips in anterior-posterior direction induced by respiratory movement.

ABSTRACT

<p><b>OBJECTIVE</b>To develop an allele-specific PCR (AS-PCR)/restriction fragment length polymorphism (RFLP) assay for CYP1B1 gene haplotypes predisposing to primary congenital glaucoma (PCG).</p><p><b>METHODS</b>Twenty Chinese PCG patients and 20 healthy controls were recruited. Peripheral blood sample was subjected to direct sequencing for common single nucleotide polymorphisms (SNPs) of the CYP1B1 gene. Based on the results, CYP1B1 gene haplotypes were constructed by PCR-RFLP and AS-PCR combined with RFLP.</p><p><b>RESULTS</b>Four SNPs loci were identified by sequencing, which included rs10012 G>C (S1 in exon 2), rs1056827 T/G (S2 in exon 2), rs1056836 C/G (S3 in exon 3) and rs1056837T>C (S4 in exon 3). The distribution of such loci showed different characteristics between the two groups. 50% of the PCG patients had rs10012 G>C and rs1056827 T>G, while 25% of PCG patients had rs1056836 C>G and rs1056837T>C. As for the controls, 25% had rs10012 G>C and rs1056827 T>G, 10% had rs1056836 C>G and rs1056837T>C. None of the SNP loci has presented alone. PCR-RFLP was carried out to confirm the results of SNPs typing, but could not confirm the linkage between the SNP loci. By contrast, AS-PCR combined with RFLP has achieved specific amplification for rs10012 G>C and thorough differentiation of 1056827 T>G polymorphism. Similar results have been obtained by the same method for rs1056836 C>G and rs1056837T>C typing and linkage disequilibrium analysis.</p><p><b>CONCLUSION</b>The AS-PCR/RFLP assay has successfully constructed the haplotypes of the CYP1B1 gene.

ABSTRACT

Objective To study the false negative results of Gelle test .Methods Hearing test data between August 2013 to July 2014 were retrieved from outpatient records with hearing complaints of tinnitus or hearing loss . Recruiting criteria:no history of otitis media ,normal tympanic membrane ,no radiologic manifestations of lesions in middle ear and mastoid and abiltly of clear expression of changes of hearing .A total of 60 patients(120 ears ) were tested with conventional pure tone audiometry (PTA) and Gelle test .Acoustic immittance and distortion product otoacoustic emission (DPOAE) were tested in 110 and 113 ears ,respectively .Results Among 120 ears ,7 were di‐agnosed as conductive hearing loss ,23 as mixed hearing loss ,52 as sensorineural hearing loss ,and 38 as normal hearing by pure tone audiometry .The negative Gelle test results were detected in 5 ,11 ,16 and 3 ears ,respective‐ly .110 ears were tested with tympanometry ,types A ,B and C tympanograms were found in 102 ears ,2 ears and 6 ears ,respectively ,and the negative Gelle test results were 22 ,2 and 4 ,respectively .DPOAEs were recordable in 56 ears and negative in 57 ears ,and negative Gelle tests were recorded in 12 and 17 ears respectively .Conclusion False-negative results were found in all types of PTA ,tympanometry and DPOAE .It indicates that Gelle test might not be sensitive and accurate enough to evaluate the integrity and mobility of ossicular chain .Gelle test com‐bined with PTA and DPOAE may be better for assessment of hearing loss and entity of ossicular chain .

ABSTRACT

Objective To explore the clinical prognostic value of rapid detection for plasma NT-proBNP levels on admission in patients with acute myocardial infarction.Methods 56 patients with AMI were measured plasma NT-proBNP imediately in hospital,and then they were divided into A,B and C group according to NT-proBNP levels (A group:< 500ng/L,B group:500-2 000ng/L,C group:> 2 000ng/L).The incidence of major adverse cardiac events (MACE including congestive heart failure,malignant arrhythmia,cardiogenic shock and sudden cardiac death) in subjects were observed respectively during hospitalisation and 30 days.Results The three group subjects with different NT-proBNP levels presented different incidence of MACE(A group:1,0;B group:3,1;C group:8,6) at duration of hospital stay,30days (x2 =6.705,P =0.035 ; x2 =7.957,P =0.008).With the NT-proBNP levels rising in AMI paitents,the inciedence of MACE increased.The incidence of MACE in A,B and C group were 6.6%,18.18% and 73.69% respectively.Conclusion In AMI patients,plasma NT-proBNP levels could predict early MACE incidence,which has an important value to evaluate the early clinical prognosis.
