ABSTRACT

Ma-Mu-Ran Antidiarrheal Capsules (MMRAC) is traditional Chinese medicine that has been used to treat diarrhea caused by acute enteritis (AE) and bacillary dysentery in Xinjiang (China) for many years. However, the potential therapeutic mechanism of MMRAC for AE and its regulatory mechanism on host metabolism is unclear. This study used fecal metabolomics profiling with GC/MS and 16S rRNA gene sequencing analysis to explore the potential regulatory mechanisms of MMRAC on a dextran sulfate sodium salt (DSS)-induced mouse model of AE. Fecal metabolomics-based analyses were performed to detect the differentially expressed metabolites and metabolic pathways. The 16S rRNA gene sequencing analysis was used to assess the altered gut microbes at the genus level and for functional prediction. Moreover, Pearson correlation analysis was used to integrate differentially expressed metabolites and altered bacterial genera. The results revealed that six intestinal bacteria and seven metabolites mediated metabolic disorders (i.e., metabolism of amino acid, carbohydrate, cofactors and vitamins, and lipid) in AE mice. Besides, ten altered microbes mediated the differential expression of eight metabolites and regulated these metabolisms after MMRAC administration. Overall, these findings demonstrate that AE is associated with metabolic disorders and microbial dysbiosis. Further, we present that MMRAC exerts protective effects against AE by improving host metabolism through the intestinal flora.

ABSTRACT

Spatiotemporal gait parameters provide important information for the rehabilitation of patients with gait dysfunction. These parameters are often obtained by complex systems such as optical motioncapture system and pressure plates. However, these systems cannot be deployed at the lower-limb rehabilitation robot easily because of high costs, large area occupation and wearable requirements. We present a gait measurement system with a Light Detection And Ranging(LIDAR) laser sensor based on the lower-limb rehabilitation robot. Firstly, to calculate gait parameters, the data are aggregated into left and right legs by the clustering algorithm and the legs contour is fitted with two circles respectively according to the least square method. Then, the spatiotemporal gait parameters are defined based on the time and position of initial contact(IC) and toe off(TO). Finally, to verify the validity of the proposed system, we compared the results of the proposed system with a 3D motion capture system based on a lower-limb rehabilitation robot. Experimental results showed that the gait detection system can measure the parameters within a small range of error that testified the validation of the proposed system. This system proved to be a valid and reliable method for the measurement of gait parameters.

ABSTRACT

OBJECTIVE@#To assess the impact of early relapse (ER) after autologous hematopoietic stem cell transplan-tation (AHSCT) on overall survival (OS) for multiple myeloma (MM) patients.@*METHODS@#Clinical data of 37 patients with MM undergoing AHSCT in department of hematology of Shanxi Bethune Hospital from January 2012 to December 2017 were retrospectively analyzed. The effect of ER on OS of patients was analyzed. The effects of international staging system (ISS) staging, cytogenetics, pre-transplant efficacy, minimal residual disease, and age on OS of the patients were also analyzed respectively.@*RESULTS@#Among the 37 patients, 13 cases (35.1%) had ER, and 24 cases (64.9%) had non-ER. 3 patients with ER had extramedullary disease, but none with non-ER showed extramedullary disease. More than or equal to very good partial rate (VGPR) in patients with ER and without ER were 3 cases (23.1%) and 15 cases (62.5%), respectively, and the curative effect of the former was significantly lower than that of the latter (P<0.05). The median follow-up time was 31 (12-96) months, and median OS time was 93 months in all the patients. The median survival time of patients with ER was 17 months, and the median progression free survival was 7 months, both were significantly shorter than 93 months and 38 months of patients with non-ER (P<0.05). Univariate analysis showed that the OS was affected by ER, cytogenetic abnormalities (FISH), and ≥VGPR before transplantation. Multivariate analysis showed that ER was an independent prognostic factor.@*CONCLUSION@#The prognosis of patients with ER after AHSCT in newly diagnosed MM is poor. ER is an independent prognostic factor of survival.

ABSTRACT

Objective:To investigate the correlations between level of serum heparin binding protein (HBP), procalcitonin (PCT), interleukin-18 (IL-18) and the severity of acute pancreatitis (AP).Methods:A total of 86 patients with AP admitted to the First Affiliated Hospital, University of Science and Technology of China from December 2017 to May 2019 were included and divided into mild AP group (MAP) with 36 cases, moderate AP group (MSAP) with 26 cases, and severe AP group (SAP) with 24 cases. There were 25 healthy subjects were chosen as the control group. Serum HBP, PCT, and IL-18 levels were dynamically monitored in all patients at 1, 3 and 7 days after admission. The Spearman correlation analysis was conducted to detect the correlation between the three indicators and inflammatory factors IL-6, IL-8, TNF-α, and APACHEII and Ranson score, and analyzed the early diagnostic value of HBP, PCT, and IL-18 in SAP patients.Results:In 86 AP patients, 53 were males and 33 were females, aged (48.3±8.0) years. In 25 healthy subjects, 15 were males and 10 were females, aged (40.5±5.9) years. Serum levels of HBP, PCT and IL-18 in AP patients were significantly higher than those of healthy control group at 1, 3 and 7 days after admission ( P<0.05), and the most significant increase was observed on the 1st day. At the meanwhile, HBP, PCT, and IL-18 were positively correlated with level of IL-6, IL-8, TNF-α, APACHEII and Ranson scores ( P<0.05). The AUC area of SAP diagnosis by using HBP, PCT or IL-18 alone was respectively 0.825, 0.896, 0.799, the Yoden index was respectively 0.605, 0.628, 0.583, the sensitivity and specificity were 75.3%, 76.2%, 74.8% and 85.2%, 86.6%, 83.5%. The AUC area, Yoden index, sensitivity and specificity of joint detection were 0.923, 0.787, 85.5%, 93.2%, and the positive predictive value and negative predictive value were also increased. Conclusion:Monitoring of serum HBP, PCT and IL-18 can predict the severity of AP patients, and it may serve as an early diagnostic marker for AP.

ABSTRACT

Acute respiratory distress syndrome (ARDS) is a common clinical critical disease, characterized by progressive respiratory distress, intractable hypoxemia, respiratory failure and so on, with high mortality rate and lack of effective prevention and treatment strategies. In recent years, mesenchymal stem cell (MSC) can be used in the treatment of acute lung injury (ALI), which cannot only replace the damaged lung epithelial cells, but also promote tissue repair and alleviate ARDS by secreting anti-inflammatory and anti-fibrosis factors. This review focuses on the related mechanisms and signal pathways of MSC and its paracrine factors in the treatment of ARDS by regulating the balance of macrophage polarization.

ABSTRACT

BACKGROUND@#Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread throughout the world. In this study, we aimed to identify the risk factors for severe COVID-19 to improve treatment guidelines.@*METHODS@#A multicenter, cross-sectional study was conducted on 313 patients hospitalized with COVID-19. Patients were classified into two groups based on disease severity (nonsevere and severe) according to initial clinical presentation. Laboratory test results and epidemiological and clinical characteristics were analyzed using descriptive statistics. Univariate and multivariate logistic regression models were used to detect potential risk factors associated with severe COVID-19.@*RESULTS@#A total of 289 patients (197 nonsevere and 92 severe cases) with a median age of 45.0 (33.0, 61.0) years were included in this study, and 53.3% (154/289) were male. Fever (192/286, 67.1%) and cough (170/289, 58.8%) were commonly observed, followed by sore throat (49/289, 17.0%). Multivariate logistic regression analysis suggested that patients who were aged ≥ 65 years (OR: 2.725, 95% confidence interval [CI]: 1.317-5.636; P = 0.007), were male (OR: 1.878, 95% CI: 1.002-3.520, P = 0.049), had comorbid diabetes (OR: 3.314, 95% CI: 1.126-9.758, P = 0.030), cough (OR: 3.427, 95% CI: 1.752-6.706, P < 0.001), and/or diarrhea (OR: 2.629, 95% CI: 1.109-6.231, P = 0.028) on admission had a higher risk of severe disease. Moreover, stratification analysis indicated that male patients with diabetes were more likely to have severe COVID-19 (71.4% vs. 28.6%, χ2 = 8.183, P = 0.004).@*CONCLUSIONS@#The clinical characteristics of those with severe and nonsevere COVID-19 were significantly different. The elderly, male patients with COVID-19, diabetes, and presenting with cough and/or diarrhea on admission may require close monitoring to prevent deterioration.

ABSTRACT

Objective@#To understand the current situation and associated factors of unintentional injury among preschool children in Shunyi District, and to provide reference for the development of unintentional injury intervention measures.@*Methods@#Three kindergartens in Shunyi district were selected through stratified cluster sampling method, and all the parents were surveyed online by self-designed questionnaire.@*Results@#The proportion of low, medium and high risk assessment of unintentional injury in preschool children were 59.5%, 37.5% and 3.0%, respectively. Risk of unintentional injury increased significantly with age and grade(χ 2=12.35, 12.70, P<0.05). The risk of unintentional injury in inter-generational care (3.7%) was higher than that in parental care(2.4%). The higher the education level of the primary caretaker and family income, the higher level of unintentional injury risk(χ 2=11.23, 14.10, P<0.05).There were significant differences in the risk for burning, poisoning, other accidental injury, prevention of accidental injury and total score of unintentional injury among children of different ages and classes(F=8.26,5.61,4.95,6.15,7.86;9.88,8.39,4.25,6.27,7.55,P<0.05). There was statistical significance in burning risk between boys and girls(t=-4.27, P<0.05). There was statistical significance in unintentional injury prevention between children of different residence(t=9.11, P<0.05). There were significant differences in behavior supervision among risk among children of different ages and grades(P<0.05). Multiple linear regression analysis showed that education level of primary caregivers (college:B=-2.66, 95%CI=-4.69--0.63; bachelor degree or higher:B=-3.80, 95%CI=-5.90--1.70), annual family income (B=-2.82, 95%CI=-4.80--0.84) were associated with unintentional injury risk of preschool children(P<0.05).@*Conclusion@#Health education of unintentional injury prevention among preschool children should focus on the primary caretaker with low education and low family income, which is crucial for prevention of children s injury.

ABSTRACT

Objective To systematically identify, describe, and evaluate research evidence related to exercise intervention in patients with depression through the evidence mapping method. Methods Related studies on exercise intervention for patients with depression were searched in CNKI, Wanfang Data, CBM, VIP, Web of Science, EMBASE, Cochrane library, and PubMed from inception to July, 2021. The quality of the studies was assessed using the risk of bias (RoB) tool recommended by the Cochrane Handbook Version 5.1.0 and A Measurement Tool to Assess Systematic Review-2 (AMSTAR-2). Based on World Health Organization Family International Classifications (WHO-FICs) framework, an evidence mapping framework was established, using EPPI software and Microsoft Excel 2019 tools for data extraction and coding, and using bubble charts to comprehensively present the research population, intervention categories, original research sample size, and the number of studies included in the systematic review/meta-analysis, conclusion classification and other information. Results A total of 101 randomized controlled trials and 52 systematic reviews/meta-analyses were included. The randomized controlled trials involved three types of intervention strategies with 15 different interventions, mainly including unspecified exercise intervention (28, 27.72%) and yoga intervention (19, 18.81%). The main research outcomes included b1. Global mental functions (92, 91.09%) and d9. Community, social and civic life (19, 18.81%). Among the three types of intervention strategies, rehabilitation accounted for the highest proportion, with 47 studies in total, accounting for 46.53%. The main research population was patients with other specified depression (19, 40.42%), such as patients with major depression and elderly depression. Forty-six research conclusions (97.87%) were classified as "beneficial" or "probably beneficial". In 52 systematic reviews/meta-analyses, nine interventions were involved, mainly including unspecified exercise intervention (17, 32.69%) and yoga intervention (12, 23.08%). The main study outcomes included b1. Global mental functions (41, 78.85%) and adverse reactions (12, 23.08%). Among the three types of intervention strategies, the treatment type accounted for the highest proportion, with a total of 34 studies, accounting for 65.38%. The study population was mainly patients with other specific depression (27, 79.41%), such as adult depression and pregnant women with depression, 28 (82.35%) of the research conclusions were classified as "beneficial" or " probably beneficial". At the same time, the intervention environment/background was mainly outpatient and inpatient environment. Conclusion Exercise intervention may be beneficial for patients with depression. However, the effectiveness of walking, cycling, Qigong, resistance training, and sports game interventions, the optimal intervention duration or intensity, and the adverse effects of the intervention, still need to be further explored by high-quality study in the future.

ABSTRACT

Objective To understand the number and prevalence of chronic filariasis patients in Hubei Province, and to provide a basis for effective care for patients. Methods The chronic filariasis patients registered in Hubei Province were interviewed to investigate the general condition of patients, the results of previous microfilaria examinations, and the current clinical symptoms, signs and onset of illness. Results A total of 487 chronic filariasis patients were investigated. The youngest was 32 years old, the oldest was 97 years old, and the average age was 76 years old. The 80-89 years old group had the largest number, accounting for 44.97%. The male accounted for 46.61%, and the female accounted for 54.39%. The occupation was dominated by farmers, accounting for 89.94%. Patients with lymphangitis accounted for 72.28%, with dermatitis accounted for 89.12%, with chyluria accounted for 11.29%, and with hydrocele accounted for 6.16%. Among the 352 patients with lymphangitis/lymphadenitis, the site of the attack was mainly at groin and lower limbs, accounting for 96.02%. Among the 433 patients with lymphedema/elephantiasis, the disease staging of the left and right legs was mainly concentrated in stage I-III, and there was no stage VII patient. Among the 55 patients with chyluria, the dysuria accounted for 30.91%. Of the 30 patients with hydrocele, 17 had tenderness, and 8 had positive light transmission tests. Conclusions Chronic filariasis patients in Hubei Province gradually decreased with the natural attrition. More care should be given by CDC at all levels and primary medical units to patients with chronic filariasis to alleviate their symptoms and improve their quality of life. Since the filariasis has not been eliminated globally, it is still necessary to strengthen the surveillance of migrant workers who go abroad to filariasis-endemic areas.

ABSTRACT

Objective@#To understand current status of drinking water and toilet sanitation in rural schools of Anhui Province, and to provide basic knowledge for environmental sanitation improvement among rural schools in Anhui.@*Methods@#One primary school and one secondary school from each of the 5 villages from 24 counties in Anhui were selected during 2014-2018. Data was collected through information review, on-site inspections and interviews.@*Results@#School water supply methods were mainly based on local water supply from villages and towns, the rate was 58.16%, 58.95%, 65.07%, 62.78%, 67.69% from 2014 to 2018, respectively. Self-supplied water in some schools was initially untreated. The proportion of schools with sanitary toilets was 66.39%, 74.88%,76.26%,82.30%,94.20% during 2014 to 2018, respectively. The proportion of schools with toilets in the teaching building is lower than 30%. Proportions of schools with squatting toilets for girls was highest in 2017 (62.78%). The number of schools with no water faucets and no soap decreased by year, the lowest of 4.02% and 56.70% in 2018.@*Conclusion@#During the past five years, improvement has been observed in drinking water supply in rural schools in Anhui Province, however, the construction of toilets and surrounding environmental facilities still needs to be strengthened. The number of female toilet squats and the number of toilets in the teaching building and in the dormitory are relatively insufficient. While increasing the scale of toilet construction, it is also necessary to strengthen the quality of toilet management, and should pay attention to the relevant health education to teachers and students.

ABSTRACT

Acute lung injury (ALI) is a common clinical critical disease, with a high mortality. The imbalance of alveolar macrophage (AMs) polarization plays an important role in the occurrence and development of ALI inflammation. The study of the regulation mode and mechanism of macrophage polarization can provide more theoretical basis for clinical prevention and treatment of ALI. In recent years, it has been found that epigenetics and immune metabolic microenvironment can affect the macrophage polarization and the immune inflammatory response of ALI. In this review, the progress of macrophage polarization, epigenetics and immune metabolism regulating macrophage polarization, the relationship between macrophage polarization and ALI were summarized, so as to clarify the effect and significance of regulating macrophage polarization on ALI, and provide new ideas for the prevention and treatment of ALI in clinic.

ABSTRACT

BACKGROUND@#Recent studies have reported circular RNA (circRNA) expression profiles in various tissue types; however, circRNA expression profile in human epicardial adipose tissue (EAT) remains undefined. This work aimed to compare circRNA expression patterns in EAT between the heart failure (HF) and non-HF groups.@*METHODS@#RNA-sequencing was carried out to compare circRNA expression patterns in EAT specimens from coronary artery disease cases between the HF and non-HF groups. Quantitative real-time polymerase chain reaction was performed for validation. Comparisons of patient characteristics between the two groups were using t test, Mann-Whitney U test, and Chi-squared test.@*RESULTS@#A total of 141 circRNAs substantially different between the HF and non-HF groups (P 2) were detected, including 56 up-regulated and 85 down-regulated. Among them, hsa_circ_0005565 stood out, for it had the highest fold change and was significantly increased in HF patients in quantitative real-time polymerase chain reaction validation. The top highly expressed EAT circRNAs corresponded to genes involved in cell proliferation and inflammatory response, including GSE1, RHOBTB3, HIPK3, UBXN7, PCMTD1, N4BP2L2, CFLAR, EPB41L2, FCHO2, FNDC3B, and SPECC1. The top enriched Gene Ontology term and Kyoto Encyclopedia of Genes and Genomes pathway were positive regulation of metabolic processes and insulin resistance, respectively.@*CONCLUSION@#These data indicate EAT circRNAs may contribute to the pathogenesis of metabolic disorders causing HF.

ABSTRACT

Objective::To study the effect of Qiyu Sanlong decoction on the growth of subcutaneous tumor in lung cancer mice and the expressions of key autophagy molecule, yeast Atg6 homologous (Beclin1), autophagy related genes5 (Atg5), and microtubule-associated protein1 light chain3 (LC3B). Method::Lewis lung carcinoma cells (LLC) were used to reproduce the lung cancer mice transplanted model. After the modeling, the mice were randomly divided into model group, Qiyu Sanlong decoction group, chemotherapy group and combination group, with 18 transplanted mice in each group. In model group, mice were fed with 0.9% saline 20 mL·kg-1 daily. In Qiyu Sanlong decoction group, mice were fed with Qiyu Sanlong decoction 80.48 g·kg-1 daily. The chemotherapy group was intraperitoneally injected with 0.4 mL cisplatin solution (DDP) at the 1st, 3rd and 5th day. The combination group was orally given the drugs at the concentration of 80.48 g·kg-1, and 0.4 mL DDP solution was intraperitoneally injected at the 1st, 3rd and 5th day. After 21 days of continuous treatment, tumor tissue was exfoliated and weighed, and the tumor inhibition rate was calculated. Hematoxylin-eosin (HE) staining was used to observe the histological changes of tumor. The expressions and localizations of Beclin1 and LC3B in tumor tissues were detected by immunohistochemical staining. Protein expressions of Beclin1, Atg5, LC3B-Ⅰand LC3B-Ⅱ were determined by Western blot, and the ratio of LC3B-Ⅱ/LC3B-Ⅰ was calculated. The transcription levels of Beclin1, Atg5 mRNA in tumor tissues were detected by Real-time PCR. Result::Qiyu Sanlong decoction had a mild inhibitory effect on transplanted tumor, with an inhibitory rate of 31.2%. Under microscope, patchy necrotic tumor cells were observed in the tumor tissues of Qiyu Sanlong decoction group. Immunohistochemical staining and Western blot analysis showed that Qiyu Sanlong decoction could up-regulate the expressions of Beclin1, Atg5 and LC3B protein (P<0.01), and promote the conversion from LC3B-Ⅰ into LC3-Ⅱ compared with the model group. Real-time PCR results showed that Qiyu Sanlong decoction could promote the transcription of Beclin1 mRNA and Atg5 mRNA compared with the model group (P<0.01). Conclusion::Qiyu Sanlong decoction has a mild inhibitory effect on lung tumors, and its mechanism may be related to up-regulating the expressions of autophagy key proteins Beclin1, Atg5 and LC3B, and promoting the conversion from LC3B-Ⅰ to LC3B-Ⅱ.

ABSTRACT

Emodin is a common Chinese medicine compound with anti-inflammatory, antibacterial, anti-oxidant and lipid-lowering effects. Modern studies have found that emodin activates adenylate-activated protein kinase (AMPK) signaling molecules and regulates transcriptional factors and biological functions of relevant pathways. Nonalcoholic fatty liver disease is a chronic liver disease with a high incidence in China. With the global prevalence of obesity and metabolic syndrome, the development of nonalcoholic fatty liver disease (NAFLD) is closely related to the expression of the metabolism-related signal molecule AMPK. AMPK is a key enzyme in glycolipid metabolism that can involve different stages of NAFLD development to non-alcoholic steatohepatitis (NASH) by regulating energy metabolism in the body. In recent years, many studies have suggested that the activation of AMPK signaling molecules is related to the function realization of emodin, and lipid synthesis, fatty acid oxidation, insulin sensitivity and mitochondrial function-related transcription factors affected by AMPK downstream signaling molecules and other biological effects can be interacted with each other. The detailed mechanism of action associated with AMPK activation provides new thought about the treatment of NAFLD by emodin. This paper mainly summarizes the research progress of emodin by participating in the various stages of NAFLD by AMPK-related signaling pathways through literature retrieval and comprehensive analysis. It lays a foundation for further research on the therapeutic effect and mechanism of emodin on NAFLD.

ABSTRACT

OBJECTIVE@#To observe the effects of acupuncture on bone mineral density (BMD), bone metabolism and intestinal function in elderly patients of primary osteoporosis with intestinal dysfunction.@*METHODS@#A total of 128 elderly patients of primary osteoporosis with intestinal dysfunction were randomly divided into an observation group and a control group, 64 cases in each group. Patients in the control group were treated with oral administration of vitamin D calcium chewable tablets (0.6 g, once a day) and calcitriol capsules (0.25 μg, three times a day); the treatment was given for 6 months. On the basis of the treatment in the control group, patients in the observation group were additionally treated with acupuncture at Shenshu (BL 23), Mingmen (GV 4), Pishu (BL 20), Dachangshu (BL 25), Tianshu (ST 25) and Zusanli (ST 36), etc. for 30 min each time, once a day. After 1-week treatment, the patients took a rest for 2 days; the treatment was given for 6 months. Before and after treatment, the BMD of lumbar spine, femoral neck and femoral trochanter was detected by dual energy X-ray absorptiometry, and the serum levels of bone alkaline phosphatase (NBAP), osteocalcin (OC), matrix metalloproteinase-2 (MMP-2) and calcitonin (CT) were detected by ELISA method. The primary symptom scores of intestinal function, serum diamine oxidase (DAO) and D-lactic acid (D-Lac) levels were compared between the two groups before and after treatment, and the clinical efficacy of the two groups was evaluated.@*RESULTS@#The total effective rate was 85.9% (55/64) in the observation group, which was higher than 71.9% (46/64) in the control group (<0.05). After treatment, BMD were increased (<0.05), and serum bone metabolism indexes were improved in the two groups (<0.05); the BMD and serum bone metabolism indexes in the observation group were better than those in the control group (<0.05). After treatment, the primary symptom scores of intestinal function, serum DAO and D-Lac levels in the observation group were decreased (<0.05), and the indexes in the observation group were lower than those in the control group (<0.05).@*CONCLUSION@#The adjuvant therapy of acupuncture could increase BMD, improve bone metabolism and regulate intestinal function in elderly patients of primary osteoporosis with intestinal dysfunction.
