ABSTRACT

BACKGROUND@#The disease burdens for endometrial cancer (EC) vary across different countries and geographical regions and change every year. Herein, we reported the updated results of the Global Burden of Disease Study 2019 on EC with respect to age-standardized incidence and mortality from 1990 to 2019.@*METHODS@#The annual percentage change (APC) of incidence and mortality was evaluated using joinpoint regression analysis to examine the temporal trends during the same timeframe in terms of the global landscape, different sociodemographic indices (SDI), and geographic regions. The relationship between Human Development Index (HDI) and incidence and mortality was additionally explored.@*RESULTS@#The age-standardized incidence rates (ASIRs) revealed a significant average global elevation by 0.5% per year (95% confidence interval [CI], 0.3-0.7; P <0.001). The age-standardized mortality rates (ASMRs), in contrast, fell by an average of 0.8% per year (95% CI, -1.0 to -0.7; P <0.001) worldwide. The ASIRs and ASMRs for EC varied across different SDIs and geographical regions. We noted four temporal trends and a significant reduction by 0.5% per year since 2010 in the ASIR, whereas we detected six consecutively decreasing temporal trends in ASMR during the entire period. Notably, the estimated APCs were significantly positively correlated with HDIs (ρ = 0.22; 95% CI, 0.07-0.35; P = 0.003) with regard to incident cases in 2019.@*CONCLUSIONS@#Incidence rates for EC reflected a significant increase overall (although we observed a decline since 2010), and the death rates declined consecutively from 1990 to 2019. We posit that more precise strategies can be tailored and then implemented based on the distinct age-standardized incidence and mortality burden in different geographical areas.

ABSTRACT

This study aimed to analyze the effect of Bletilla striata polysaccharide(BSP) on endogenous metabolites in serum of tumor-bearing mice treated with 5-fluorouracil(5-FU) by untargeted metabolomics techniques and explore the mechanism of BSP in alleviating the toxic and side effects induced by 5-FU. Male BALB/C mice were randomly divided into a normal group, a model group, a 5-FU group, and a 5-FU + BSP group, with eight mice in each group. Mouse colon cancer cells(CT26) were transplanted into the mice except for those in the normal group to construct the tumor-bearing mouse model by subcutaneous injection, and 5-FU chemotherapy and BSP treatment were carried out from the second day of modeling. The changes in body weight, diarrhea, and white blood cell count in the peripheral blood were recorded. The mice were sacrificed and sampled when the tumor weight of mice in the model group reached approximately 1 g. TUNEL staining was used to detect the cell apoptosis in the small intestine of each group. The proportions of hematopoietic stem cells and myeloid progenitor cells in bone marrow were measured by flow cytometry. Five serum samples were selected randomly from each group for untargeted metabolomics analysis. The results showed that BSP was not effective in inhibiting colon cancer in mice, but diarrhea, leukopenia, and weight loss caused by 5-FU chemotherapy were significantly improved after BSP intervention. In addition, apoptotic cells decreased in the small intestinal tissues and the percentages of hematopoietic stem cells and myeloid progenitor cells in bone marrow were significantly higher after BSP treatment. Metabolomics results showed that the toxic and side effects of 5-FU resulted in significant decrease in 29 metabolites and significant increase in 22 metabolites in mouse serum. Among them, 19 disordered metabolites showed a return to normal levels in the 5-FU+BSP group. The results of pathway enrichment indicated that metabolic pathways mainly involved pyrimidine metabolism, arachidonic acid metabolism, and steroid hormone biosynthesis. Therefore, BSP may ameliorate the toxic and side effects of 5-FU in the intestinal tract and bone marrow presumably by regulating nucleotide synthesis, inflammatory damage, and hormone production.

ABSTRACT

Objective: Through comparative analysis of the disease burden of occupational pneumoconiosis in Gansu Province from 2010 to 2020, the main influencing factors are screened, and scientific basis is provided for rational allocation of limited health resources, precise management and policy implementation. Methods: In August 2021, survey and collect information on surviving occupational pneumoconiosis patients and dead occupational pneumoconiosis patients diagnosed in Gansu Province from 2010 to 2020, and analyze and calculate indicators such as morbidity, mortality, and disability adjusted of life years (DALY). Analyzing the influencing factors of disease burden usirrg multiple linear regression. Results: From 2010 to 2020, the average annual incidence of occupational pneumoconiosis in Gansu Province was 0.9992/100000, the average annual mortality was 0.897/100000, the cumulative case fatality rate was 25.75%, and the cumulative DALY was 28932.96 person-years. The first stage of occupational pneumoconiosis was the highest among DALY loss (19920.14 person-years), and the DALY loss was positively correlated with the stage of occupational pneumoconiosis. Among occupational pneumoconiosis in Gansu Province, silicosis (13753.66 person-years) and coal worker's pneumoconiosis (13414.73 person-years) caused the highest disease burden, followed by cement pneumoconiosis and asbestos lung. Period, length of service, type of disease, and region are all influencing factors of DALY loss (P<0.05). Conclusion: From 2010 to 2020, the DALY losses caused by occupational pneumoconiosis in Gansu Province showed a fluctuating decrease, with the composition of DALY mainly changing from the loss of life years due to premature death to the loss of years due to injury and disability.

ABSTRACT

Objective To investigate the distribution and drug resistance of pathogenic bacteria for infection after liver transplantation, and to provide a scientific basis for the rational clinical application of antibiotics. Methods The pathogenic bacteria isolated from the specimens of 904 patients with infection after liver transplantation in The Affiliated Hospital of Qingdao University from March 2014 to December 2021 were analyzed in terms of distribution and drug resistance. WHONET 5.6 software was used to perform a statistical analysis of strains and bacterial resistance rate, and Excel was used to analyze the sources of specimens, composition ratios, and distribution of pathogenic bacteria. Results A total of 2 208 non-repetitive pathogenic bacteria were isolated, mainly from the specimens of respiratory tract (31.25%), bile (22.28%), ascites (13.18%), blood (8.38%), and drainage fluid (4.62%). The top 10 pathogenic bacteria were Klebsiella pneumoniae subspecies (10.69%), Enterococcus faecium (10.42%), Escherichia coli (8.24%), Pseudomonas aeruginosa (8.24%), Staphylococcus epidermidis (8.06%), Acinetobacter baumannii (7.93%), Stenotrophomonas maltophilia (6.61%), Enterobacter cloacae (3.22%), Staphylococcus haemolyticus (3.08%), and Staphylococcus aureus (2.94%), accounting for 69.43% of the total pathogenic bacteria. Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Klebsiella pneumoniae subspecies, and Acinetobacter baumannii were the main pathogenic bacteria isolated from respiratory tract specimens; Enterococcus faecium was the main pathogenic bacterium isolated from bile, ascites, and drainage fluid specimens; Escherichia coli , Staphylococcus epidermidis , and Klebsiella pneumoniae subspecies were the main pathogenic bacteria isolated from blood specimens. Drug sensitivity data showed that Enterobacterales bacteria had a relatively high resistance rate to cephalosporins and fluoroquinolones and a resistance rate of 50% to macrolides, fluoroquinolones, sulfonamides, and lincomycin, and a small part of these strains were resistant to linezolid and quinupristin/dalfopristin (< 3%), with no Staphylococcus epidermidis strains resistant to tigecycline and vancomycin. A total of 287 drug-resistant strains were monitored, accounting for 13%, among which there were 128 carbapenem-resistant Acinetobacter baumannii strains, 88 carbapenem-resistant Pseudomonas aeruginosa strains, 26 carbapenem-resistant Klebsiella pneumoniae subspecies strains, 11 carbapenem-resistant Escherichia coli strains, 23 methicillin-resistant Staphylococcus aureus strains, and 11 vancomycin-resistant Enterococcus strains. The carbapenem-resistant Klebsiella pneumoniae subspecies strains mainly produced serine carbapenemase, and the carbapenem-resistant Escherichia coli strains mainly produced metal β-lactamase. Conclusion Gram-negative bacteria are the main pathogenic bacteria for infection after liver transplantation, and there are differences in the distribution of pathogenic bacteria between different types of specimens. The resistance rate of some strains tend to increase, and therefore, it is necessary to strengthen the management of nosocomial infection and antibiotics.

ABSTRACT

Objective: To investigate the prevalence of tonsil hypertrophy in patients with different sagittal skeletal craniofacial patterns, as well as the correlation between tonsil hypertrophy and the type of skeletal pattern. Methods: Lateral cephalograms of patients who visited the Department of Orthodontics Division 1, School of Stomatology, Wuhan University during January to August, 2019 were retrospectively collected. Patients (children: age≥6 and ≤12 year; adults: age≥18 year) were divided into three groups according to the ANB (subspinale-nasion-supramental) angle: the skeletal class Ⅰ group (0°≤ANB≤4°), skeletal class Ⅱ group (ANB>4°) and skeletal class Ⅲ group (ANB<0°). Tonsil hypertrophy was diagnosed with lateral cephalogram by two specifically trained orthodontists independently, according to the Baroni's method. The between-group differences in tonsil hypertrophy prevalence were analyzed using chi-square tests with Bonferroni correction (α=0.017). Results: A total of 1 776 patients (593 children and 1 183 adults) were included, among which 672 (37.8%) were with class Ⅰ, 849 (47.8%) with class Ⅱ, and 255 (14.4%) with class Ⅲ skeletal pattern. The prevalence of tonsil hypertrophy in children was 66.3% (393/593). The proportion of children with tonsil hypertrophy in class Ⅲ group [87.0% (60/69)] were significantly higher than that in class Ⅰ [65.6% (145/221), χ²=11.56, P<0.017] and class Ⅱ [62.0% (188/303), χ²=15.69, P<0.017] groups. The prevalence of tonsil hypertrophy in adults was 23.2% (275/1 183). The proportion of adults with tonsil hypertrophy in class Ⅲ group [42.5% (79/186)] was significantly higher than that in class Ⅰ [19.1% (86/451), χ²=36.50, P<0.017] and class Ⅱ [20.2% (110/546), χ²=35.00, P<0.017] groups. However, there was no significant difference in the prevalence of tonsil hypertrophy between class Ⅰ and class Ⅱ groups for both children (χ²=0.70, P>0.017) and adults (χ²=0.18, P>0.017). Conclusions: The prevalence of tonsil hypertrophy in skeletal class Ⅲ patients was significantly higher than that in patients with skeletal class Ⅰ and Ⅱmalocclusion. Tonsil hypertrophy could be an important risk factor for skeletal class Ⅲ patients.

ABSTRACT

Objective:To investigate basic public health service personnel allocation in five regions of Guizhou province, providing reference and strategies for the construction of grass-roots disease prevention and control system in Guizhou province and the training of grass-roots public health service talents in colleges and universities.Methods:According to the topographical features of Guizhou province, stratified random sampling was completed in five regions including Guiyang, Zunyi, Liupanshui, Qianxinan Buyei and Miao Autonomous Prefecture, Qiannan Buyei and Miao Autonomous Prefecture. Questionnaires and on-the-spot symposiums were conducted among basic public health service personnel from 20 township health centers and 20 community health service centers.Results:Women (82.7%), 25-35 years of age (41.7%), working years < 5 years (65.7%), and junior professional titles (59.7%) accounted for a higher proportion of the staff in the five regions. Basic public health service personnel in Guiyang had the highest percentage of undergraduate education (47.5%) and those in other regions had the highest percentage of a junior college education. 40.3% and 26.4% of basic public health service personnel were devoted to nursing and clinical specialties, and only 3.2% of basic public health service personnel were devoted to general practice and preventive medicine. The number of public health practitioners (assistants) per 10,000 residents was 0.05, and 43.5% of public health practitioners had multiple duties.Conclusion:The professional structure of public health personnel is not reasonable at the grass-roots level in Guizhou province. There is an extreme shortage of public health practitioners (assistants), the professional title is low, staffing is inadequate, and staff loss is serious.

ABSTRACT

Impaired immunomodulatory capacity and oxidative stress are the key factors limiting the effectiveness of mesenchymal stem cell transplantation therapy. The present study was aimed to investigate the effects of jujuboside A (JuA) on the protective effect and immunomodulatory capacity of human umbilical cord mesenchymal stem cells (hUC-MSCs). Hydrogen peroxide was used to establish an oxidative damage model of hUC-MSCs, while PBMCs isolated from rats were used to evaluate the effect of JuA pre-treatment on the immunomodulatory capacity of hUC-MSCs. Furthermore, Hoechst 33258 staining, lactate dehydrogenase test, measurement of malondialdehyde, Western blot, high-performance liquid chromatography; and flow cytometry were performed. Our results indicated that JuA (25 μmol·L-1) promoted the proliferation of hUC-MSCs, but did not affect the differentiating capability of these cells. JuA pre-treatment inhibited apoptosis, prevented oxidative damage, and up-regulated the protein expression of nuclear factor-erythroid factor 2-related factor 2 and heme oxygenase 1 in hUC-MSCs in which oxidative stress was induced with H2O2. In addition, JuA pre-treatment enhanced the inhibitory effect of hUC-MSCs against abnormally activated PBMCs, which was related to stimulation of the expression and activity of indoleamine 2,3-dioxygenase. In conclusion, our results demonstrate that JuA pre-treatment can enhance the survival and immunomodulatory ability through pathways related to oxidative stress, providing a new option for the improvement of hUC-MSCs in the clinical setting.

ABSTRACT

Objective@#The role of the protein-coding gene arylacetamide deacetylase (AADAC) in the prognostication of ovarian cancer remains uncertain. We aimed to identify and validate its prognostic value using integrated bioinformatics analyses. @*Methods@#Gene expression profiles of RNA-sequencing and microarray data were retrieved from The Cancer Genome Atlas and Gene Expression Omnibus. Univariate and multivariate Cox regression models were used to evaluate the prognostic value of gene expression. The predictive accuracy of the gene signature model was evaluated using a time-dependent receiver operating characteristic (ROC) curve. In addition, the correlation between immune infiltration and AADAC was identified. A nomogram of the gene signature with clinical parameters was constructed to estimate the clinical application of the signature for survival prediction in patients with ovarian cancer. @*Results@#Univariate and multivariate Cox regression analyses in the training and validation cohorts indicated that a high AADAC expression signature was significantly and independently correlated with better survival outcomes in ovarian cancer. AADAC upregulation positively correlated with the infiltration of CD4+ memory T cells. Immunological signature gene sets were significantly enriched in CD4+ T cell regulation pathways. The area under the curve of the time-dependent ROC for overall survival indicated that the constructed nomogram had a moderate predictive ability for prognostic prediction in ovarian cancer. @*Conclusion@#AADAC expression signature significantly and independently correlated with the survival outcome and CD4+ memory T cell infiltration in ovarian cancer, indicating its potential applicability in the prediction of prognosis and immunotherapy efficacy.

ABSTRACT

Lysophosphatidylcholine (LPC) modulates the dynamic and integral process of macrophage polarization in immune responses, tissue inflammation and remodeling. Patatin-like phospholipase domain containing protein 7 (PNPLA7) was identified as an LPC-preferring lysophospholipase recently. However, the expression and role of PNPLA7 in macrophage polarization remained unknown. In the present study, PNPLA7 was found to be upregulated in the process of macrophage polarization toward an alternatively activated (M2) phenotype stimulated with interleukin 4 (IL-4) (P<0.05). We found that knockdown and overexpression of PNPLA1 decreased and increased the expression of M2 marker genes, including arginase 1 (Argl) and chitinase-like 3 (Ym\ ), respectively (P<0.05). Further studies showed that PNPLA7 regulated the expression of peroxisome proliferator activated receptor-γ (P P A R γ) at the mRNA and protein levels during M2 polarization (P < 0.05). However, the phosphorylation of signal transducer and activator of transcription 6 (STAT6) was not influenced by PNPLA7. These findings suggest that PNPLA7 favors macrophage anti-inflammatory M2 polarization through a PPAR

ABSTRACT

OBJECTIVE@#To explore the value of PCR-flow fluorenscence immunmicrobeads assay in prenatal gene diagnosis of thalassemia.@*METHODS@#A total of 1001 pregnant women and their couples checked in the First Affiliated Hospital of Sun Yat-Sen University from January 2016 to August 2019 were selected. Both pregnant women and their spouses were the carriers of thalassemia gene. Samples such as amniotic fluid, were used to extract genomic DNA at the right time. Parallel detection of α- and β- thalassemia genes to samples should be carried out by PCR-flow cytometric fluorescence hybridization and traditional multiple Gap-PCR and PCR-RDB techniques. The consistency of two methods in gene diagnosis of thalassemia was evaluated by analyzing the results of detection.@*RESULTS@#389 normal genotypes (38.86%, 389/1001) and 59 abnormal genotypes (61.14%, 612/1001) was cheked out by the two methods, including 416 cases of α-thalassemia, 162 cases of β-thalassemia and 34 cases of αβ- complex thalassemia. The main genotypes of α-thalassemia were --@*CONCLUSION@#Guangzhou is a area with high incidence of thalassemia, and the genetic types of thalassemia are complex and diverse. Prenatal diagnosis is the final barrier to the prevention of thalassemia. PCR flow-cytometric fluorescence hybridization, as a simple and fast technique, combined with traditional techniques in parallel contributed to the accuracy of prenatal gene diagnosis of thalassemia.

ABSTRACT

Objective: To investigate the independent risk factors of cardiorenal syndrome type 1 (CRS1) in patients with acute myocardial infarction (AMI) and to build a predictive equation for the development of CRS1 in these patients. Method: Consecutive inpatients with AMI, who hospitalized from January 2017 to December 2018 in the Hunan Provincial People's Hospital, were enrolled in this case-control study. Patients were divided into CRS1 group and non-CRS1 group according to the presence or absence of CRS1.The clinical data were collected through the electronic medical record system of Hunan Provincial People's Hospital. The matching process was conducted with a minimum-distance scoring method and a 1∶1 match between the CRS1 group and the no-CRS1 group, the propensity score was calculated through the logistic regression model. Factors with statistically significant differences in univariate analysis were included in the multivariate logistic regression model to analyze the risk factors of AMI patients with CRS1, then the independent risk factors were used to establish a predicting equation for CRS1 by logistic regression function for model building. Area under the curve (AUC) value and the best cut-off value of the combined predictors was determined according to the ROC curve. Python 3.8 software was used to perform 10-fold cross-validation on modeling samples. Results: A total of 942 patients were included, there were 113 cases in CRS1 group and 829 cases in non-CRS1 group. Ultimately, 99 CRS1 patients were successfully matched to 99 non-CRS1 patient using 1∶1 matching. After propensity score matching, the baseline age and sex along with heart rate, mean arterial pressure, percentage of people with a history of diabetes, hypertension, ST-segment elevation myocardial infarction, myocardial ischemia time, angiotensin converting enzyme inhibitors or angiotensin Ⅱ receptor blockers use, and β receptor blocker use were similar between the two groups(all P>0.05). The contrast agent dosage was also similar between the two groups (P=0.266). The peak cardiac troponin I (cTnI), N-terminal pro-brain natriuretic peptide(NT-proBNP), white blood cell count, base estimated glomerular filtration rate (eGFR), albumin and hemoglobin levels were statistically significant between the two groups (all P<0.05). Multivariate logistic regression analysis showed that decreased baseline eGFR, increased NT-proBNP, peak cTnI concentrations and white blood cell count were independent risk factors of CRS1 in AMI patients (all P<0.01).The predicting equation of the combined predictor was established by transforming the logistic model equation, L=0.031×cTnI+0.000 2×NT-proBNP-0.024×eGFR+0.254×white blood cell count, where L represented the combined predictor. ROC curve analysis indicated that the AUC of the peak cTnI, NT-proBNP, baseline eGFR, white blood cell count, and combined predictor were 0.76, 0.85, 0.79, 0.81, and 0.92 respectively (all P<0.05), and the cutoff value of combined predictor was 2.6. The AUC of ROC curve after the model's ten-fold cross validation was 0.89. Conclusions: Decreased baseline eGFR, increased NT-proBNP, peak cTnI concentrations and white blood cell count are the independent risk factors for CRS1 in AMI patients. The combined predictor equation based on the above 4 biomarkers presents a good predictive value for CRS1 in AMI patients.

ABSTRACT

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.

ABSTRACT

Objective:To establish a high performance liquid chromatography (HPLC) fingerprint of branches of <italic>Juglans mandshurica</italic> and to evaluate the quality of the samples from different producing areas and in different harvest periods. Method:Chromatographic separation was performed on an Agilent Poroshell 120 SB-C<sub>18</sub> column (2.1 mm×100 mm, 2.7 μm) for gradient elution with mobile phase of 0.2% formic acid solution (A)-0.2% formic acid acetonitrile solution (B) (0-5 min, 5%-10%B; 5-25 min, 10%-16%B; 25-40 min, 16%-22%B; 40-45 min, 22%-45%B; 45-50 min, 45%-65%B; 50-52 min, 65%-100%B; 52-55 min, 100%B) at a flow rate of 0.3 mL·min<sup>-1</sup>. The column temperature was 30 ℃ and the detection wavelength was 270 nm. The quality of branches of <italic>Juylans mandshurica</italic> was evaluated by similarity evaluation, cluster analysis, principal component analysis and partial least squares-discriminant analysis. The chemical constituents of the samples were identified by HPLC coupled with quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF-MS/MS). The mass spectrometry was conducted in negative ion mode with electrospray ionization(ESI). Data were acquired over a range of <italic>m</italic>/<italic>z</italic> 100-1 700 for MS and <italic>m</italic>/<italic>z</italic> 50-1 700 for MS/MS. Result:A total of 19 common peaks were confirmed in 40 batches of samples, and the similarity ranged from 0.430 to 0.995, of which the similarity of samples collected in spring and winter seasons (April, May and December) was greater than 0.90, while the similarity of most samples collected in summer (July to September) was low. Multivariate statistical analysis showed that the samples were divided into two groups according to the harvest time, but there was no obvious classification rule for the samples from different producing areas. The contents of most constituents in the samples collected in spring and winter were higher than those collected in summer. The result illustrated that different harvest periods had great influence on the quality of branches of <italic>J</italic>.<italic> mandshurica</italic>. Compared with the samples collected in summer, the quality of samples collected in spring and winter was better. A total of 22 peaks were proved to be the main constituents that contributed to the difference between samples collected in different seasons. A total of 83 chemical components were identified by HPLC-Q-TOF-MS/MS, including 49 tannins, 7 organic acids, 14 naphthalene derivatives, 1 flavonoid, 6 anthracene derivatives, 2 lignans, 3 diarylheptanoids and 1 saccharide. Totally 13 common peaks were identified. Of the peaks that contributed to discriminate samples collected in different season, 19 peaks were identified and most of them were tannins. Conclusion:The established HPLC fingerprint can provide useful information for the quality evaluation of branches of <italic>J</italic>.<italic> mandshurica</italic>. Tannin is the main constituents in the samples. Harvest period has great influence on the quality of branches of <italic>J</italic>.<italic> mandshurica</italic>.

ABSTRACT

Objective:To study the soil physical and chemical properties, microorganisms, and metabolites in different culture environments of <italic>Gastrodia elata</italic>, so as to provide scientific basis for subsequent cultivation of <italic>G. elata</italic> in multiple environments. Method:The tubersphere soil of <italic>G. elata</italic> cultured in different environments was collected for analyzing the soil nutrients, microbial numbers, and metabolite differences using the agrochemical method, plate-count method, and gas chromatography-time-of-flight mass spectrometry (GC-TOF-MS)-based non-targeted metabonomic approach. Result:The analysis of soil physical and chemical properties revealed the highest soil moisture, pH, available potassium, and available phosphorus in the spinney and the highest electrical conductivity, total nitrogen, alkali-hydrolyzable nitrogen, and organic matter in the pinewood. As demonstrated by the quantitative analysis of soil microorganisms, the cultivable microorganisms were bacteria, actinomycetes, and fungi, with the bacterial population and total microbial biomass in the spinney and the number of fungi and actinomycetes in the barren slope detected to be the largest. The ratio of bacteria to fungi (B/F value) in the pinewood was the highest, while that in the barren slope was the lowest. The results of metabonomic research demonstrated that the compositions and quantities of soil metabolites in the spinney (Z group), pinewood (S group), and barren slope (HD group) varied. Through comparisons between S and Z groups, between HD and Z groups, as well as between HD and S groups by orthogonal partial least squares discriminant analysis (OPLS-DA), 18, 35, and 24 differential metabolites were separately screened out, and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis yielded 5, 9, and 13 metabolic pathways. There existed a significant causal relationship of the soil physical and chemical properties and microbial numbers with the metabolites. Conclusion:The soil physical and chemical properties, microbial numbers, and metabolite changes differed significantly in different culture environments of <italic>G. elata</italic>, which were sorted by the suitability in a descending order as follows: spinney > pinewood >barren slope. The soil physical and chemical properties and microbial numbers are the crucial factors driving changes in soil metabolites, suggesting that regulating the soil physical and chemical characteristics and microbial characteristics in the culture environment is an important mechanism for maintaining the <italic>G. elata</italic>-soil-microbial symbiotic system.

ABSTRACT

Background: A novel method for inducing hyphae formation, was described.Methods:Mycelia of experimental and clinical strains from 100 patients with oral lichen planuswere cultured in RPMI 1640 medium with 56°C or 121°C inactivated calf sera. After these strains were cultured for 2 h to 7 days, the average hyphae formation rate was observed under light microscopy. Results: The 121°C inactivated calf serum showed better outcomes than 56°C inactivated calf serum in terms of time and amounts of hyphae products. Conclusions:For Candida albicanshyphae culture, the 121°C inactivated serum is superior to the 56°C inactivated serum

ABSTRACT

Burning mouth syndrome (BMS) is a complex chronic disorder characterized symptomatically by burning sensation mainly localized in the tongue with no specific lesions. Its etiology is not fully understood. Due to the persistent pain and unsatisfactory outcome of treatment, patients with high expectation when seeking medical advice easily feel discontent after treatment, which might cause medical dispute. This review introduces the epidemiology, manifestations, etiology, diagnosis, classification and treatment of BMS. The authors hope the current advances about BMS, mainly focus on the etiology of biological nerve and social psychology, may help the clinicians in treatment of BMS.

ABSTRACT

Corona Virus Disease 2019 (COVID-19) has broke out in 29 countries and regions in the world in a short period since December 2019. Various measures of prevention and control have been taken all over China. At present, the epidemic situation shows a positive trend, however, there are still a few new comfirmed cases in some area of China. So the job and thinking of epidemic prevention still cannot be relaxed. As an important specialty of stomatology, the risk of cross infection is high in oral medicine. Establishing an effective system of pre- inspection and triage and adopting strict measures of prevention and control are essential. According to the prevention and control situation of COVID- 19, the characteristics of hospital infection, pre examination, protective measures, the home management strategies of oral mucosal diseases during the epidemic period and the differential diagnosis between COVID-19 and common oral muco- sal diseases with fever were summarized and recommended in this paper.
