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

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

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

Purpose@#Tumor regression grade (TRG) has been widely used in gastrointestinal carcinoma to assess pathological responses to neoadjuvant chemotherapy (NCT). There are various standards without a consensus, and it is still unclear which kind of system has better predictive value. This study aims to investigate and compare the predictive ability of the Mandard and Becker TRGs in patients with locally advanced gastric cancer. @*Materials and Methods@#A total of 290 patients with locally advanced gastric adenocarcinoma who underwent NCT and curative surgery were studied. Survival analysis for overall survival (OS) and disease-free survival (DFS) were based on the Kaplan-Meier method and Cox proportional hazards method. Predictive values of TRGs and models were assessed by time-dependent receiver operating characteristic (ROC) curve, the area under the ROC curve (AUC), nomogram, and calibration curve. @*Results@#In multivariable analysis, the Mandard TRG was associated with OS (hazard ratio [HR], 1.806; p=0.026) and DFS (HR, 1.792; p=0.017). The Becker TRG was also related to OS (HR, 1.880; p=0.014) and DFS (HR, 1.919; p=0.006). The Mandard and Becker TRG AUCs for 5-year survival were 0.72 and 0.71, respectively. The whole models showed an increased predictive value, with AUCs of 0.85 and 0.86, respectively. There was no significant difference between the two TRGs and two models. @*Conclusion@#TRG was an independent predictor for survival, and there was no significant difference between these two systems.

ABSTRACT

Objective To investigate the indoor air quality in urban and rural areas in Xi'an, to analyze the relationship between indoor pollutants and living habits, and to study the impact of pollutants on health, so as to provide reference for improving indoor environment. Methods Through random cluster sampling, 29 families from rural areas and 53 families from urban areas were selected from Xi'an. Data was collected by questionnaire survey and on-site environmental sampling. Non-parametric test and Chi-square test were used for statistical analysis. Results Overall, the values of CO, NO2, toluene and xylene in Xi'an were far lower than the national standards. The medians of CO2, PM2.5, PM10, and formaldehyde were 0.1%, 44.5 μg/m3, 51.5 μg/m3, and 34.5 μg/m3, respectively. The differences in the values of CO, NO2, formaldehyde, toluene and xylene in urban and rural areas were statistically significant (P2 were higher in families with humidifiers and potted plants (P2 were higher in families with pets (P10, CO, and NO2 were significantly correlated with children's sleep duration and colds (P<0.05). Conclusion The indoor air pollution in urban areas is higher than that in rural areas in Xi'an. It is suggested that residents should be cautious about the use of humidifiers, planting potted plants, and keeping pets, to reduce indoor air pollution and improve their health.

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

This study analyzed the trend in semen quality of infertile male patients in Wenzhou, China, based on the data obtained from 38 905 patients during 2008-2016 in The First Affiliated Hospital of Wenzhou Medical University (Wenzhou, China). The results showed that only 24.9% of the patients had normal semen quality. For the semen quality of infertile male patients, that of the workers and 40-year-olds was significantly worse than the other occupational and age groups. For all the infertile patients, low semen volume, asthenozoospermia, and teratozoospermia accounted for 8.4%, 50.5%, and 54.1%, respectively. During 2008-2016, the annual mean percentage of fast forward motile spermatozoa, percentage of total forward motile spermatozoa, and percentage of spermatozoa with normal morphology decreased linearly with slopes of -2.11, -2.59, and -0.70, respectively. The proportion of patients with asthenozoospermia and multi-abnormal spermatozoa increased during 2008-2016 with slopes of 4.70 and 4.87, respectively, while for low semen volume, it decreased with a slope of -0.47 in the same time period. The proportion of patients with teratozoospermia increased from 2008 to 2011 and from 2011 to 2016 with slopes of 17.10 and 2.09, respectively. In general, the deteriorating trend of semen quality of infertile male patients in Wenzhou was obvious. Future efforts should be made to reveal the adverse influences on semen quality, such as occupational exposure, environmental quality, and living habits. Furthermore, more pervasive reproduction health education is necessary.

ABSTRACT

Dendrobium huoshanense is a precious medicinal plant belonging to Dendrobium of Orchidaceae. It is a special medicinal material and extremely scarce in Huoshan county, Anhui province. At present, D. huoshanense has been greatly protected, which also makes it possible to industrialize relying on tissue culture and artificial cultivation technology. Three main planting methods were utilized for cultivating D. huoshanense including facility cultivation, under forest cultivation and simulative habitat cultivation. Firstly, the three cultivation modes and technical characteristics of D. huoshanense were compared and analyzed, and it was found that the ecological environment of D. huoshanense cultivated in the simulated environment was closer to that of wild D. huoshanense. Secondly, based on comparing the characters and quality of three cultivation modes, the results showed that the shape of D. huoshanense cultivated in simulated environment was more similar to that of "grasshopper thigh" recorded in Bencao Jing Jizhu, and its quality was better than that of facilities and under forest cultivation. The comprehensive benefit comparison of three modes showed that the simulated cultivation had high income, the lowest input-output ratio and significant economic benefit. The quality of cultivated D. huoshanense was further evaluated from four aspects of "excellent environment" "excellent shape" "high quality" "excellent effect", which summarized the comprehensive advantages of simulative habitat cultivation of D. huoshanense as follows: the original habitat and site environment of simulated wild D. huoshanense, the closer shape to the wild, the more content of main medicinal components, and higher economic benefit and better efficacy. The quality of D. huoshanense was improved by the use of simulative habitat cultivation, which has practical significance to guide its large-scale cultivation.

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 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

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.

ABSTRACT

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@#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
