ABSTRACT

Objective To investigate the risk factors of central airway stenosis after lung transplantation. Methods Clinical data of 155 recipients undergoing lung transplantation in Wuxi People's Hospital Affiliated to Nanjing Medical University from July 2016 to December 2017 were retrospectively analyzed. According to the incidence of central airway stenosis following lung transplantation, all recipients were divided into the stenosis group (n=36) and control group (n=119). The incidence of central airway stenosis after lung transplantation was summarized. The risk factors of central airway stenosis after lung transplantation were assessed by univariate and multivariate logistic regression analyses. Results Among 155 lung transplant recipients, 36 cases (23.2%) developed central airway stenosis. The average incidence time was (53±13) d after lung transplantation. Univariate analysis demonstrated that bilateral lung transplantation, grade 3 primary graft dysfunction (PGD), airway fungal infection, long cold ischemia time, long mechanical ventilation time and long intensive care unit (ICU) stay were the risk factors for central airway stenosis after lung transplantation (all P < 0.05). Multivariate analysis showed that airway fungal infection, long cold ischemia time and long mechanical ventilation time were the independent risk factors for central airway stenosis after lung transplantation (all P < 0.05). Conclusions Airway fungal infection after lung transplantation, long cold ischemia time and long mechanical ventilation time probably lead to central airway stenosis after lung transplantation. Active preventive measures and intimate monitoring should be taken to improve the quality of life of the recipients after lung transplantation.

ABSTRACT

Obesity is increasingly prevalent globally, searching for therapeutic agents acting on adipose tissue is of great importance. Equisetin (EQST), a meroterpenoid isolated from a marine sponge-derived fungus, has been reported to display antibacterial and antiviral activities. Here, we revealed that EQST displayed anti-obesity effects acting on adipose tissue through inhibiting adipogenesis in vitro and attenuating HFD-induced obesity in mice, doing so without affecting food intake, blood pressure or heart rate. We demonstrated that EQST inhibited the enzyme activity of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), a therapeutic target of obesity in adipose tissue. Anti-obesity properties of EQST were all offset by applying excessive 11β-HSD1's substrates and 11β-HSD1 inhibition through knockdown in vitro or 11β-HSD1 knockout in vivo. In the 11β-HSD1 bypass model constructed by adding excess 11β-HSD1 products, EQST's anti-obesity effects disappeared. Furthermore, EQST directly bond to 11β-HSD1 protein and presented remarkable better intensity on 11β-HSD1 inhibition and better efficacy on anti-obesity than known 11β-HSD1 inhibitor. Therefore, EQST can be developed into anti-obesity candidate compound, and this study may provide more clues for developing higher effective 11β-HSD1 inhibitors.

ABSTRACT

OBJECTIVES@#To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.@*METHODS@#A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.@*RESULTS@#Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).@*CONCLUSIONS@#There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

ABSTRACT

Objective@#SET8 is a member of the SET domain-containing family and the only known lysine methyltransferase (KMT) that monomethylates lysine 20 of histone H4 (H4K20me1). SET8 has been implicated in many essential cellular processes, including cell cycle regulation, DNA replication, DNA damage response, and carcinogenesis. There is no conclusive evidence, however, regarding the effect of SET8 on radiotherapy. In the current study we determined the efficacy of SET8 inhibition on radiotherapy of tumors and the underlying mechanism.@*Methods@#First, we explored the radiotherapy benefit of the SET8 expression signature by analyzing clinical data. Then, we measured a series of biological endpoints, including the xenograft tumor growth in mice and apoptosis, frequency of micronuclei, and foci of 53BP1 and γ-H2AX in cells to detect the SET8 effects on radiosensitivity. RNA sequencing and subsequent experiments were exploited to verify the mechanism underlying the SET8 effects on radiotherapy.@*Results@#Low expression of SET8 predicted a better benefit to radiotherapy in lung adenocarcinoma (LUAD) and invasive breast carcinoma (BRCA) patients. Furthermore, genetic deletion of SET8 significantly enhanced radiation treatment efficacy in a murine tumor model, and A549 and MCF7 cells; SET8 overexpression decreased the radiosensitivity. SET8 inhibition induced more apoptosis, the frequency of micronuclei, and blocked the kinetics process of DNA damage repair as 53BP1 and γ-H2AX foci remained in cells. Moreover, RNF8 was positively correlated with the SET8 impact on DNA damage repair.@*Conclusion@#Our results demonstrated that SET8 inhibition enhanced radiosensitivity by suppressing DNA damage repair, thus suggesting that SET8 potentiated radiotherapy of carcinomas. As new inhibitors of SET8 are synthesized and tested in preclinical and clinical settings, combining SET8 inhibitors with radiation warrants consideration for precise radiotherapy.

ABSTRACT

This paper was aimed to clarify the effect of high-intensity interval training (HIIT) on depression. Animal running platforms were used to establish HIIT exercise models, depression models were prepared by chronic unpredictable mild stress (CUMS), and depression-related behaviors were detected by behavioral experiments. The results showed that HIIT exercise improved depression-related behavior in CUMS model mice. Western blot and ELISA results showed that in the hippocampus, medial prefrontal cortex (mPFC) and amygdala of the CUMS model mice, glucocorticoid receptor (GR) protein expression was down-regulated, and the content of tumor necrosis factor α (TNF-α) was increased, compared with those in the control group, whereas HIIT exercise could effectively reverse these changes in CUMS model mice. These results suggest that HIIT exercise can exert antidepressant effect, which brings new ideas and means for the clinical treatment of depressive diseases.

ABSTRACT

Drug repositioning provides new clinical indications for existing drugs. The imbalance between body's "immune-inflammation" regulation is one of the important factors in the occurrence and development of diabetic nephropathy (DN). Chinese patent medicine Kunxian capsule is clinically used for treating rheumatoid arthritis with satisfying immune-modulatory and anti-inflammatory actions. Notably, accumulating clinical evidence based on small cohorts had shown that Kunxian capsule may be used to treat DN. But the underlying pharmacological mechanisms remain unclear. Therefore, this study integrated "drug target-disease gene-biological pathway-function module" multi-level associated network analysis, and in vivo and in vitro experiments, to verify the pharmacological effects of Kunxian capsules in DN and to elucidate its molecular mechanisms. The experimental protocol was reviewed by the Laboratory Animal Welfare and Ethics Committee of China Academy of Chinese Medical Sciences, and it complies with the relevant regulations on laboratory animal welfare and ethics. As a result, the network analysis showed that the candidate targets of Kunxian capsule against DN were significantly involved into various functional modules which were related to modulation of immune-inflammation system, basement membrane lesion, abnormal hemorheology, energy metabolism and hormone metabolism, and the number of targets enriched by PI3K/AKT/NF-κB pathway is the largest. In addition, both in vivo and in vitro experiments demonstrated that Kunxian capsule by gavage effectively reduced blood glucose, improved insulin resistance, reduced blood lipid, inhibited renal extracellular matrix protein production and renal inflammation, improved renal function and pathological damages, and inhibited the activity of PI3K/AKT/NF-κB/TNF-α/IL-1β pathway in diabetic nephropathy rats. Collectively, these findings suggest the therapeutic potentials of Kunxian capsule to alleviate DN by regulating the imbalance of immune-inflammation system.

ABSTRACT

ABSTRACT Objective: Recently, several studies have found that obesity had a protective effect against varicocele, but no meta-analysis has confirmed this finding. Therefore, we conducted this meta-analysis to investigate the association between body mass index (BMI) and varicocele. Material and Methods: We searched for studies in PubMed, Science Direct and the Cochrane Library from inception until February 2018. The association between BMI and varicocele was assessed by pooling the odds ratios (ORs). Results: Eleven eligible studies with a total study population of 1.376.658 participants were included in our analysis. According to BMI, the subjects were defined as belonging to the obese, overweight and underweight groups. Our results showed that the obese group had a lower risk of varicocele when compared with the normal weight group (odds ratio [OR] 0.46, 95% confidence intervals [CIs] 0.37-0.58). Additionally, an overweight BMI had a protective effect against varicocele (OR 0.70, 95% CIs, 0.56-0.86). However, underweight patients had a more than 30% higher risk of varicocele (OR 1.31, 95% CI, 1.04-1.64). Furthermore, there was no publication bias in any of the analyses. Conclusions: Our study demonstrates that BMI is negatively associated with the presence of varicocele.

ABSTRACT

Objective To analyze the epidemiological characteristics and the detection of pathogenic microorganisms in the cases of foodborne diseases under active surveillance in Xi'an, and to provide references for prevention and control of foodborne diseases. Methods Information on surveillance cases of foodborne diseases reported by two sentinel hospitals in Xi'an from 2017 to 2019 was collected. Data was statistically analyzed. Results From 2017 to 2019, a total of 904 cases of active surveillance of foodborne diseases were reported by two active surveillance sentinel hospitals in Xi'an. There were more cases in the age groups of 1-5 and 5-8, accounting for 35.18% and 20.02%, respectively. There was a statistically significant difference in the number of cases reported in four quarters(χ2=545.38,P2=321.92,P2= 26.49,P2=92.17,P<0.05) in different seasons, and the detection rate was higher in the first and fourth quarters. Conclusion The main pathogens of food-borne diseases are Norovirus and Salmonella in Xi'an. It is suggested that active surveillance should be strengthened. The prevention and control knowledge of foodborne diseases should be carried out according to the epidemiological characteristics.

ABSTRACT

Lung cancer is the malignant tumor with the highest incidence in China. Early detection and identification of symptomatic lung cancer patients and timely screen out asymptomatic patients from high-risk groups require multiple cooperation. At present, although combined imaging, serology, genomics, proteomics and other methods have been combined to screen for suspected lung cancer, there are still problems such as missed diagnosis and misdiagnosis. Meanwhile, the spread of the corona virus disease 2019 (COVID-19) epidemic has brought new challenges to early lung cancer screening. Under the normalization of epidemic prevention and control, the work of early lung cancer screening should be changed accordingly: improve the population's awareness of cancer prevention and control, strengthen the management of medical procedures, improve the efficiency of tumor detection, optimize detection technology, and utilize internet and big data platforms rationally. We should establish an ideal model, combining multiple screening methods, which is streamlined and efficient for early lung cancer screening under normal epidemic prevention and control.

ABSTRACT

OBJECTIVE@#High-fat diet (HFD) and inflammation are two key contributors to nonalcoholic fatty liver disease (NAFLD). Shenling Baizhu powder (SLBZP), a classical herbal compound, has been successfully used to alleviate NAFLD. However, its specific mechanisms are not fully understood. In this study, we assessed the anti-NAFLD effect of SLBZP in vivo.@*METHODS@#Rats were fed an HFD with or without SLBZP or with probiotics. At the end of week 16, an echo magnetic resonance imaging (EchoMRI) body composition analyser was used to quantitatively analyse body composition; a micro-computed tomography (micro-CT) imaging system was used to evaluate whole body and liver fat; and the Moor full-field laser perfusion imager 2 was used to assess liver microcirculation, after which, all rats were sacrificed. Then, biochemical indicators in the blood and the ultrastructure of rat livers were evaluated. Protein expression related to the liver Toll-like receptor 4 (TLR4)/Nod-like receptor family pyrin domain-containing 3 (NLRP3) signalling pathway was assessed using Western blot analysis. Further, high-throughput screening of 29 related inflammatory factors in liver tissue was performed using a cytokine array.@*RESULTS@#SLBZP supplementation reduced body weight, serum free fatty acid, and insulin resistance index (P < 0.05). It also ameliorated liver microcirculation and ultrastructural abnormalities. EchoMRI and micro-CT quantitative analyses showed that treatment with SLBZP reduced fat mass and visceral fat (P < 0.05 and P < 0.01, respectively). In addition, SLBZP decreased the expression of lipopolysaccharide (LPS)-activated TLR4/NLRP3 signalling pathway-related proteins and altered the expression levels of some inflammatory cytokines in liver tissues.@*CONCLUSION@#SLBZP can inhibit NLRP3 inflammasome activation and interleukin-1β release by suppressing LPS-induced TLR4 expression in rats with HFD-induced NAFLD. Thus, SLBZP may be beneficial for the prevention and treatment of inflammatory damage and associated diseases.

ABSTRACT

Spermatogenic dysfunction caused by cyclophosphamide (CP) chemotherapy has seriously influenced the life quality of patients. Unfortunately, treatments for CP-induced testicular spermatogenic dysfunction are limited, and the molecular mechanisms are not fully understood. For the first time, here, we explored the effects of bone marrow mesenchymal stem cell-derived exosomes (BMSC-exos) on CP-induced testicular spermatogenic dysfunction in vitro and in vivo. BMSC-exos could be taken up by spermatogonia (GC1-spg cells). CP-injured GC1-spg cells and BMSC-exos were cocultured at various doses, and then, cell proliferation was measured using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay. In addition, photophosphorylation of extracellular-regulated kinase (ERK), p38 mitogen-activated protein kinase (p38MAPK), and protein kinase B (AKT) proteins was evaluated by western blotting as well as apoptosis in GC1-spg cells measured using flow cytometry. Treatment with BMSC-exos enhanced cell proliferation and reduced apoptosis of CP-injured GCI-spg cells. Phosphorylated levels of ERK, AKT, and p38MAPK proteins were reduced in CP-injured spermatogonia when co-treated with BMSC-exos, indicating that BMSC-exos acted against the reproductive toxicity of CP via the p38MAPK/ERK and AKT signaling pathways. In experiments in vivo, CP-treated rats received BMSC-exos by injection into the tail vein, and testis morphology was compared between treated and control groups. Histology showed that transfusion of BMSC-exos inhibited the pathological changes in CP-injured testes. Thus, BMSC-exos could counteract the reproductive toxicity of CP via the p38MAPK/ERK and AKT signaling pathways. The findings provide a potential treatment for CP-induced male spermatogenic dysfunction using BMSC-exos.

ABSTRACT

Accurate methods for identifying pelvic lymph node metastasis (LNM) of prostate cancer (PCa) prior to surgery are still lacking. We aimed to investigate the predictive value of peripheral monocyte count (PMC) for LNM of PCa in this study. Two hundred and ninety-eight patients from three centers were divided into a training set (n = 125) and a validation set (n = 173). In the training set, the independent predictors of LNM were analyzed using univariate and multivariate logistic regression analyses, and the optimal cutoff value was calculated by the receiver operating characteristic (ROC) curve. The sensitivity and specificity of the optimal cutoff were authenticated in the validation cohort. Finally, a nomogram based on the PMC was constructed for predicting LNM. Multivariate analyses of the training cohort demonstrated that clinical T stage, preoperative Gleason score, and PMC were independent risk factors for LNM. The subsequent ROC analysis showed that the optimal cutoff value of PMC for diagnosing LNM was 0.405 × 109 l

ABSTRACT

As a local variety of medicinal material, Citri Trifoliatae Fructus is widely used in many places, whereas its harvest time remains unclear. Therefore, studying its harvest time can make more reasonable use of this medicinal material. In this study, we determined the flavonoids content and compared the color of Citri Trifoliatae Fructus harvested in different time, aiming to guide the harvest of this medicinal material. The fresh fruits of Citrus trifoliata were collected from Xinxiang city, Henan province, graded according to the diameter range, and then dried. The contents of isonaringin, naringen, and poncirin in Citri Trifoliatae Fructus were determined by HPLC, and the color values of the samples were detected by electronic eye. The correlation analysis of the obtained data was carried out to explore the relationships of color and diameter with quality. The results showed that the contents of isonaringin, naringen, and poncirin varied significantly in different harvest time, within the ranges of 0.21-1.20, 2.21-11.59, and 3.73-23.16 mg·g~(-1), respectively. With the delay of harvest time, Citri Trifoliatae Fructus showed the color changing from green to yellow, gradually increased diameter, and gradually decreased contents of isonaringin, naringen, and poncirin. The contents of isonaringin, naringen, and poncirin were negatively correlated with the degree of red and green(a~*) and positively correlated with the degree of yellow and blue(b~*). The contents of naringen and poncirin had significantly negative correlations with the diameter. This study indicates that the quality of Citri Trifoliatae Fructus can be judged by its diameter and skin color, which provides a theoretical basis for the rational harvest of this medicinal material.

ABSTRACT

Objective:To evaluate a new type of draw-bar skin stretcher in repair of full-thickness skin defects.Methods:From May 2015 to January 2019, 52 patients with full-thickness skin defects were repaired with a new type of draw-bar skin stretcher at Daping Hospital, Army Medical University. They were 40 males and 12 females, aged from 4 to 61 years (average, 37.1 years). Their skin was stretched for primary wound closure. When primary wound closure failed, skin stretching was performed again to close the wound depending on the wound condition. When the Pinch test was negative after skin stretching, the wound was sutured directly. In cases of positive Pinch test, a skin graft or flap was used to repair the remaining wound. At 12 months after surgery, scar contracture and size of skin graft or flap were observed and wound healing after skin stretching was evaluated in comparison with the original wound.Results:After skin stretching, one-stage wound closure was achieved in 36 cases and multi-stage wound closure in 8 cases; of the remaining 8 cases, 2 were repaired by skin graft and 6 by skin flap after their wounds were reduced by skin stretching. In one-stage closed wounds, infection occurred in 3 cases and marginal necrosis in 5 cases; in the wounds repaired by skin graft or flap, no infection or necrosis was observed. The 12-month follow-up for all the patients showed fine healing of all the wounds after one-stage or multi-stage closure, linear scar, absence of scar contracture, and smaller wound sizes than the original ones after skin graft or flap repair.Conclusions:Skin stretching using our new type of draw-bar skin stretcher is an effective treatment for skin wounds. It can replace traditional skin grafting and flap surgery in some cases, but its indications should be strictly followed to avoid related complications.

ABSTRACT

OBJECTIVE Baicalin is a major flavonoid component of Scutellaria baicalensis, and has been used in the treatment of liver diseases for many years. However, the role of baicalin in estrogen-induced cholestasis (EIC) remains to be elucidated. This present study explored the protective effect of baicalin against estrogen-induced liver injury and further elucidated the mechanisms involved both in vivo and in vitro. METHODS We conducted a series of experiments using 17α-ethinylestradiol (EE) induced cholestatic rats and cultured HepG2 cells. Serum, bile, and liver samples were collected for biochemical and histological analyses. Bile acid composition in liver was analyzed by LC-MS/MS. The mechanisms underlying the hepatoprotective of baicalin were investigated by RT-PCR, Western blotting analyses and immunohistochemistry. RESULTS Baicalin showed obvious hepatoprotective effects in EIC rats by reducing serum bio?markers and increasing the bile flow rate, as well as by alleviating liver histology and restoring the abnormal composition of hepatic bile acids (BAs). In addition, baicalin protected against EE induced liver injury by up-regulation of the expres?sion of hepatic efflux transporters and down-regulation of hepatic uptake transporters. Furthermore, baicalin increased the expression of hepatic BA synthase (CYP27A1) and metabolic enzymes (Bal, Baat and Sult2a1) in EIC rats. We showed that baicalin significantly inhibited hepatic inflammatory responses in EIC rats through reducing elevated levels of TNF-α, IL-1β, IL-6 and NF-κB. Finally, we confirmed that baicalin maintains BA homeostasis and alleviates inflamma?tion through Sirt1/HNF-1α/FXR signaling pathway. CONCLUSION Baicalin protects against estrogen-induced cholestatic liver injury, and the underlying mechanism involved is related to activation of the Sirt1/HNF-1α/FXR signaling pathway.

ABSTRACT

Objective:To explore the mechanism and compatibility characteristics of Baimai ointment (BMO) in the treatment of white vein disease from the network perspective based on system theory, so as to provide biological basis for its clinical application. Method:The chemical components and the corresponding candidate target spectra of BMO were obtained from The Encyclopedia of Traditional Chinese Medicine (ETCM) and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP). According to the clinicopathological characteristics of white vein disease, focusing on four diseases/symptoms including neuropathic pain, inflammatory pain, chronic pain and lumbar disc herniation root neuralgia, the gene sets related to white vein disease were collected in Human Phenotype Ontology (HPO), DisGeNET and other databases, then the interaction network of the targets of active components in BMO-gene sets related to white vein disease was constructed. On this basis, the hub network nodes were selected and enriched for exploring the mechanism of four functional groups of BMO in the treatment of white vein disease such as Huoxue Tongluo group (Curcumae Longae Rhizoma, Moschus, Tronae), Xingqi Zhitong group (Myristicae Semen, Nardostachyos Radix et Rhizoma, Acori Calami Rhizoma), Wenjing Sanhan Tongluo group (Zingiberis Rhizoma, Zanthoxyli Pericarpium, Caraway) and Jianpi Wenshen Qianggu group (Actinolite, Glycyrrhizae Radix et Rhizoma). Result:The enriched pathways of the four functional groups in BMO were mainly distributed in three modules of nervous system function, inflammation-immune system regulation and body energy metabolism, and each module was connected by common target genes especially had its own focus. Among them, the regulation of nervous system function in Huoxue Tongluo group and Xingqi Zhitong group could be summarized as Huoxue Buqi and Xingshen Kaiqiao. Xingqi Zhitong group and Jianpi Wenshen Qianggu group were mainly used to promote the operation of Qi, promote blood metaplasia, enhance immunity and maintain the regulation of inflammation-immune system. Jianpi Wenshen Qianggu group and Wenjing Sanhan Tongluo group mainly regulated body energy metabolism by invigorating the spleen and supplementing Qi as well as warm-heat medicine. The whole formula focused on the multi-dimensional and multi-level mechanism of BMO in the intervention of white vein disease. Each functional group emphasized its respective characteristics in nervous system function, inflammation-immune regulation, and body energy metabolism. Two types of networks analysis models complemented and verified each other. Conclusion:BMO plays a role in the treatment of white vein disease mainly by regulating the function of nervous system, maintaining the balance of inflammation-immune system and interfering with energy metabolism. The relevant research results can provide reference for the in-depth exploration of the mechanism of BMO, and help to guide the clinical rational use of this preparation.

Asari Radix et Rhizoma (ARR) is a traditional Chinese medicine for relieving exterior syndrome, and its roots and stems contain rich chemical components, including volatile oils (terpenoids, aromatics and aliphatics), lignans, flavonoids, etc. Clinically, it has been traditionally used for the treatment of diseases such as phlegm and cough, anemofrigid cold, rheumatic arthralgia due to its ability to spread cold. Modern pharmacological studies have shown that ARR played beneficial roles in analgesic, anti-inflammatory, antitussive, antiasthmatic, antiviral, antibacterial, sedative, antioxidative, and antidepressant responses, antihypertension, as well as tumor suppression. The current studies on the chemical composition of ARR mainly focused on volatile components, and little information is available for the occurrence and pharmacological effects of non-volatile components. In addition, there is a lack of clear classification of chemical components and the distribution of chemical components in medicinal parts and the origin of species. Therefore, in this study, the authors reviewed a large number of literature on the chemical compositions and pharmacological effects of ARR, and hoping to provide a reference for further pharmacological research and the new drug development of ARR.

ABSTRACT

OBJECTIVE: To analyze the funding status of the National Natural Science Fund(NNSF) in the field of occupational respiratory disease(ORD) research in China. METHODS: Through the NNSF Committee Science Foundation sharing service network database, we collected the information of funded projects in the field of ORD research in China from 1987 to 2018, and analyzed the funding expenditure, funding categories, supporting units and research contents. RESULTS: A total of 106 NNSF funded projects were obtained in the research field of ORD in China in the period 1987-2018, and the total amount of funding was 37.945 million yuan. The number of funded projects, the average and the total amounts of fundings showed an increasing trend year by year(all P<0.05). The main types of funded projects were general projects and Youth Science Foundation projects(97.2%). The funded projects and funds were mainly concentrated in colleges and universities, accounting for 79.2% and 83.4% respectively. Beijing(29 items, 27.4%), Hebei(13 items, 12.3%) and Jiangsu(11 items, 10.4%) were the top three provinces and municipalities in the number of funded projects. Silicosis, pulmonary fibrosis, quartz, alveolar macrophages and acute lung injury were the top five keywords of funded project items, and the research types mainly focused on the mechanism of diseases. CONCLUSION: The NNSF funding is imbalanced in the types of funding, supporting units, and regional distribution on ORD research field in China. It is suggested that the funding structure of NNSF should be optimized, interdisciplinary research should be encouraged and expanded, and cooperation among different institutions and regions should be promoted.
