ABSTRACT
@#Abstract: Objective To investigate the clinical and laboratory characteristics of pulmonary infection caused by Nocardia otitidiscaviarum. Methods The clinical data of a patient with pulmonary infection caused by Nocardia otitidiscaviarum were reported, and the clinical characteristics, laboratory characteristics and drug sensitivity of pulmonary infection caused by Nocardia otitidiscaviarum were summarized in combination with the relevant literature at home and abroad from January 2010 to December 2022. Results A 67-year-old female patient was admitted to the hospital on June 30, 2020 because of "repeated chest tightness and shortness of breath for 3 years, aggravated cough, expectoration and fever". The sputum, alveolar lavage fluid and blood of the patient were collected for culture, and the detected pathogenic bacteria were identified. There are pathogenic bacteria growing in sputum and alveolar lavage fluid, which are identified as Nocardia otitidiscaviarum by Autof ms mass spectrometer. According to the results of pathogenic bacteria and the patient's condition, meropenem combined with compound sulfamethoxazole tablets were given anti-infection treatment, and the patient's condition improved and discharged. Conclusion The clinical manifestations and imaging features of nocardiosis are lack of specificity, and are prone to misdiagnosis and missed diagnosis. Etiology is the key to disease diagnosis, and clinical examination and culture should be conducted in time.
ABSTRACT
ObjectiveTo analyze the multimorbidity and comorbid disease patterns among middle-aged and older adults aged 50 years and above in China and to study the prevalence， regional distribution， and relationship with health-related outcomes of major comorbid disease patterns. MethodsThe fourth national follow-up data of the China Health and Retirement Longitudinal Study （CHARLS） 2018 was used， including 13 774 respondents aged 50 years and older from 28 provincial units. We analyzed 14 patient-reported physician-diagnosed chronic diseases and multimorbidity combinations， reported prevalence， composition ratio， and regional distribution. Differences in health loss and risk factors between high morbidity groups were analyzed using chi-square tests and logistic regression. ResultsThe prevalence of multimorbidities among participants was 57.3%. The single disease with high prevalence included arthritis/rheumatism （6.47%）， hypertension （5.41%）， and gastric and digestive disorders （4.17%）； the binary multimorbidity combinations were arthritis + digestive disorders （3.06%）， arthritis + hypertension （2.61%）， and hypertension + hyperlipidemia （1.39%）； the triadic combinations were hypertension + digestive disorders + joint disorders （1.00%）. The prevalence of multimorbidity varied greatly between provinces， showing the characteristics of high in the west and north but low in the east and south China. Significant differences in the health loss caused by different multimorbidity combinations were noted， with the highest ADL loss （28.51%） and depression （77.68%） caused by the arthritis multimorbidity combinations （P<0.01）. The number of chronic diseases （OR=6.71， P<0.01）， age （OR=1.96， P<0.01）， and heavy alcohol consumption were comorbid risk factors for physical and mental health； exercise （OR=0.44， P<0.01） and sleep （OR=0.89， P<0.01） were protective factors for physical and mental health， and smoking cessation （OR=0.76， P<0.01） contributed to the relief of anxiety. ConclusionsThe prevalence of comorbid patterns showed a high clustering trend， and the health loss caused by major patterns varied greatly. Relevant health intervention strategies should prioritize the major multimorbidity combinations for targeted disease management and rehabilitation services.
ABSTRACT
Objective: To investigate the current situation of job involvement of nurses in military hospitals in Henan Province and analyze the influencing factors, so as to provide reference for improving the level of job involvement of military nurses. Methods: In February 2022, the employed nurses of 4 military hospitals in Henan Province were investigated by convenient sampling method. A total of 663 questionnaires were collected, including 632 valid questionnaires, with an effective recovery rate of 95.32%. The self-designed questionnaire was used to investigate the basic information of nurses, the Job Involvement Scale was used to investigate the job involvement of nurses, the Emotional Labor Scale for Nurses was used to investigate nurses' emotions, and the Work-Family Conflict Scale was used to investigate the work-family conflict of nurses. Independent sample t-test and univariate analysis of variance were used to compare the job involvement of military employed nurses with different demographic characteristics, Pearson correlation analysis was used to explore the correlation between emotional labor, work-family conflict and job involvement, and hierarchical regression analysis was used to explore the impact of relevant variables on the job involvement of military employed nurses. Results: The total average score of job involvement of military employed nurses was (3.68±1.13), and the scores of vitality, dedication and focus were (3.64±1.15), (3.74±1.25) and (3.67±1.21) respectively. The total score of emotional labor of nurses was 33-80 (62.95±8.12), with an average score of (3.93±0.51). The total score of work-family conflict was 18-94 (55.16±13.53), with an average score of (3.06±0.75). Professional emotional regulation, patient-centered emotional inhibition and standardized emotional play were positively related to the job involvement (r=0.46, 0.41, 0.22, P<0.01). Time-based conflict, stress-based conflict and behavior-based conflict had negative correlation with the job involvement (r=-0.12, -0.23, -0.20, P<0.01). In hierarchical regression analysis, after controlling demographic variables, emotional labor and work-family conflict accounted for 17.2% and 4.2% of the variation of job involvement. Conclusion: The job involvement of military employed nurses tends to be at a moderate level. Emotional labor and work-family conflict can significantly affect their job involvement.

Molecular knowledge of human gastric corpus epithelium remains incomplete. Here, by integrated analyses using single-cell RNA sequencing (scRNA-seq), spatial transcriptomics, and single-cell assay for transposase accessible chromatin sequencing (scATAC-seq) techniques, we uncovered the spatially resolved expression landscape and gene-regulatory network of human gastric corpus epithelium. Specifically, we identified a stem/progenitor cell population in the isthmus of human gastric corpus, where EGF and WNT signaling pathways were activated. Meanwhile, LGR4, but not LGR5, was responsible for the activation of WNT signaling pathway. Importantly, FABP5 and NME1 were identified and validated as crucial for both normal gastric stem/progenitor cells and gastric cancer cells. Finally, we explored the epigenetic regulation of critical genes for gastric corpus epithelium at chromatin state level, and identified several important cell-type-specific transcription factors. In summary, our work provides novel insights to systematically understand the cellular diversity and homeostasis of human gastric corpus epithelium in vivo.

In order to clarify the pharmacodynamic substances and mechanism of Xiangju Preparations (Xiangju Tablets, Xiangju Drops) in the treatment of rhinitis and sinusitis, the multi-level network integration analysis of "ingredients-targets-pathways" was conducted. 137 chemical constituents were identified in Xiangju Preparations by high pressure liquid chromatography-quadrupole-time of flight mass spectrometry (HPLC-QTOF/MS) for the first time. Network pharmacology analysis was performed on 59 potential active components. The results of network pharmacology analysis demonstrated that the medicinal ingredients in Xiangju Preparations included caffeic acid, senkyunolide F, rosmarinic acid, ligustilide, prim-O-glucosylcimifugin, linarin, magnolin, luteolin, senkyunolide I and gallic acid. These ingredients act on the crucial targets of tumor necrosis factor (TNF), interleukin 1B (IL1B), protein kinase B (AKT1), vascular endothelial growth factor A (VEGFA), signal transducer and activator of transcription 3 (STAT3) and participate in the regulation of advanced glycosylation end products-receptor of AGEs (AGE-RAGE), TNF, nuclear factor kappa B (NF-κB), and cyclic guanosine monophosphate-protein kinase G (cGMP-PKG) signaling pathways to effectively treat rhinitis and sinusitis. The excellent binding performance between above 10 active components and 5 key target proteins was further confirmed by molecular docking, indicating that these 10 ingredients are pharmacodynamic substances of Xiangju preparations. In conclusion, this study preliminarily clarified the effective components and mechanism of Xiangju preparations in the treatment of rhinitis and sinusitis, and provided a theoretical basis for the clinical application of Xiangju preparations.
ABSTRACT
According to the notice on revision of the instructions for traditional Chinese medicine injections(TCMIs) issued by the National Medical Products Administration(NMPA) from January 2006 to May 2020, the revised contents in the instructions for 29 varieties involved in the notice were sorted out, and the existing problems in the instructions for TCMIs were analyzed, so as to provide the basis for dynamic revision of the instructions. It was found that the revised items of instructions for 29 varieties all involved adverse reactions, contraindications and precautions, and warnings were added for 82.76% of 29 TCMIs preparations, indicating that all the revised contents were related to safety issues. In addition, 33.33% of the drugs risks mentioned in the precautions were not indicated in the adverse reactions; 82.76% instructions did not indicate drug interactions; 17.24% instructions lacked medication notes for special populations; 48.28% instructions did not indicate traditional Chinese medicine(TCM) syndromes of the main disease; 44.83% instructions did not indicate the type and stage of indication; and 86.21% instructions did not indicate the course of treatment. It could be concluded that the instructions for TCMIs have known risks of drugs that are not fully reflected in adverse reactions and the effective information is not comprehensive. The risk control measures proposed in the precautions need to have aftereffect evaluation and there is a lack of drug interactions and medications for special populations. As an important part of the full life-cycle management of drugs, the revision of instructions for TCMIs should be continuously improved to provide the basis for safe and reasonable application of TCMIs. Based on the above problems, it is proposed that the marketing license holder as the main body of the revision of instructions should actively carry out post-marketing basic and clinical research in accordance with the characteristics of TCM, combine the updated research with the guidance of TCM theory and improve the revision level of instructions for TCMIs to provide the basis for post-marketing evaluation.

Objective:To investigate changes in serum C3d and C5b-9 levels in elderly patients with idiopathic membranous nephropathy(IMN)and their correlations with prognosis.Methods:Two hundred thirty-one elderly patients with IMN and 96 non-elderly patients with IMN confirmed by kidney biopsy at the First Affiliated Hospital of Zhengzhou University from January 2015 to May 2017 were enrolled.During the same period, 118 healthy individuals receiving health checkups were included as controls.Patients were divided into the low C3d group( n=112)and the high C3d group( n=113)according to the median level of serum C3d.Serum C3d and C5b-9 levels were measured by enzyme-linked immunosorbent assays. Results:Serum C3d and C5b-9 levels in elderly IMN patients were 0.23(0.15, 0.45)mg/L and 0.28(0.20, 1.23)mg/L, respectively, which were higher than those in healthy controls[0.18(0.13, 0.22)mg/L, 0.22(0.16, 0.26)mg/L, respectively]( Z=-4.261 and -6.213, P<0.001). Serum C3d levels in elderly and non-elderly IMN patients were correlated negatively with the estimated glomerular filtration rate( r=-0.155 and -0.426, P=0.019 and 0.000), but positively with serum creatinine, anti-phospholipase A2 receptor(PLA2R)antibody levels and 24 h urinary protein( r=0.184, 0.326, 0.407, 0.321 and 0.145, P=0.005, 0.001, 0.000, 0.001 and 0.027). Kaplan-Meier survival analysis showed that the cumulative renal survival rate in elderly IMN patients was lower in the high C3d group than in the low C3d group(47.8% vs.70.8%, Log Rank χ2=7.399, P=0.007). Multivariate Cox regression analysis showed that high C3d levels were an independent risk factor for poor renal outcomes in elderly IMN patients( HR=2.288, 95% CI: 1.082-4.839, P=0.030). Conclusions:High serum C3d levels are associated with increases in urinary protein excretion and anti-PLA2R antibody levels, renal function decline, and poor renal outcomes in elderly IMN patients.
ABSTRACT
Objective:To detect serum level of complement factor B (CFB), and to explore its correlations with clinical parameters and prognosis in children with primary IgA nephropathy (IgAN).Methods:A total of 204 children with primary IgAN confirmed by kidney biopsy in the Department of Nephrology of the First Affiliated Hospital of Zhengzhou University from December 2014 to April 2017 were included in IgAN group.During the same period, 84 healthy children were included in healthy control group.Their mean age was (11.0±3.5) years and (10.9±3.2) years, respectively.Patients in IgAN group were divided into low CFB group (102 cases) and high CFB group (102 cases) according to the medium serum level of CFB measured by enzyme-linked immunosorbent assay. Spearman′ s coefficient was employed to analyze correlation amongst various parameters.Multivariable-adjusted Cox proportional ha-zards models were used to evaluate the relationship between serum CFB level and prognosis in children with IgAN. Results:Serum CFB levels were significantly higher in IgAN group than that in healthy control group [290.9 (186.2-453.9) mg/L vs.218.9 (155.0-321.3) mg/L, Z=-3.372, P=0.001]. Serum levels of CFB were negatively correlated with serum albumin ( r=-0.388, P<0.001) and estimated glomerular filtration rate ( r=-0.416, P<0.001), but positively correlated with serum creatinine ( r=0.305, P<0.001) and 24 h urinary protein ( r=0.456, P<0.001) in IgAN group.The incidences of crescents (C1-2) (70.6% vs.29.4%, χ2=34.588, P<0.001) and C 3 deposition (+ + -+ + + ) (63.7% vs.44.1%, χ2=7.892, P=0.005) were significantly higher in high CFB group than those in low CFB group. Kaplan- Meier analysis showed that high CFB levels predicted worse renal outcome in pediatric IgAN patients ( χ2=17.509, P<0.001). Multivariate Cox regression analysis showed that the high CFB level was the independent risk factor for the poor renal outcome ( HR=2.517, 95% CI: 1.284-4.932, P=0.007). Conclusions:High serum levels of CFB are associated with decreased renal function, increased urinary protein excretion, crescentic formation and poor renal outcome in pediatric IgAN patients.
ABSTRACT
Objective To explore the effect of acupuncture-rehabilitation therapy on the expression of transcription factor forkheadbox P3 (Foxp3) and retinoic acid-related orphan receptor γt (RORγt) protein in cerebral ischemic mice. Methods Forty-five female C57BL/6 mice were randomly assigned to sham operation group, model group, acupuncture group, rehabilitation group, and acupuncture-rehabilitation group, with nine mice in each group. Subsequently, each group was divided into three days, seven days and 14 days subgroups. The permanent middle cerebral artery occlusion models were established by the suture method, except the sham operation group. The sham operation group and the model group received no treatment. The acupuncture group received scalp cluster acupuncture, the rehabilitation group received treadmill training, and the acupuncture-rehabilitation group received scalp cluster acupuncture combined with treadmill training. Three days, seven days and 14 days after modeling, the modified Neurological Severity Score (mNSS) was obtained, and the expression of Foxp3 and RORγt in brain tissue of ischemic side was analyzed by Western blotting. Results The mNSS in the sham operation group was 0, and was higher in the model group than in the sham operation group at each postoperative time point. Three days after operation, the mNSS decreased in the rehabilitation group and the acupuncture-rehabilitation group, compared to the model group (P < 0.05). Fourteen days after operation, the mNSS decreased in the acupuncture-rehabilitation group, compared to the model group and acupuncture group (P < 0.05). The expression of Foxp3 protein was significantly lower in the acupuncture-rehabilitation group than in other groups at all time points after surgery( P < 0.05). Three days after operation, the expression of RORγt was higher in the acupuncture-rehabilitation group than in other groups (P < 0.05). Seven days after operation, the expression of RORγt was higher in the acupuncture-rehabilitation group than in the acupuncture group and sham operation group (P < 0.05). Conclusion Acupuncture-rehabilitation therapy may improve the tissue injury of cerebral ischemia mice, and promote the recovery of neural function, possibly by regulating Foxp3 and RORγT expression to reduce the level of inflammation, and then exert neuroprotective effects.

ABSTRACT
Objective:To design a type of wearable cephalic stimulator and verify its feasibility, safety and effectiveness. Methods:The wearable cephalic stimulator was designed based on transcranial electric stimulation and the meridian. From June 2015 to February 2018, 80 patients with ischemic stroke were randomly divided into control group (n = 40) and treatment group (n = 40). The control group accepted routine rehabilitation, and the treatment group was treated with the wearable cephalic stimulator additionally, for four weeks. They were assessed with Fugl-Meyer Assessment (FMA) and modified Barthel index (MBI) before and after treatment. While, the safety and stability of the device were observed, and the temperature, pulse, respiration, blood pressure, etc. of the patient were recorded. Results:The prototype was successfully produced. There was no significant difference in the scores of FMA and MBI between two groups before treatment (P > 0.05). The scores of FMA and MBI significantly increased in both groups (t > 2.448, P < 0.05), and they were higher in the observation group than in the control group (|t| > 2.202, P < 0.05) after treatment. The temperature, pulse, and breathing did not change during the treatment with this device, and blood pressure did not increase. Conclusion:The wearable cephalic stimulator is safe, reliable and operability, and could effectively improve the motor function and activities of daily living in patients with acute ischemic stroke.

ABSTRACT
Objective:To investigate the effects of enriched environment on hippocampal neuronal apoptosis and brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB) signaling pathway in neonatal rats with hypoxic-ischemic brain damage. Methods:Forty-eight newborn Wistar rats aged seven days were randomly divided into sham operation group, model group and enriched environment group, each group was divided in to 14 days group and 28 days group, with eight in each subgroup. The model was established with the Rice method. The sham operation group and the model group did not receive any intervention, and the enriched environment group received enriched environment stimulation 24 hours after modeling. Fourteen days and 28 days after modeling, the levels of neuronal apoptosis in hippocampus were detected by TUNEL and double immunofluorescence staining; BDNF and TrkB proteins in hippocampus were detected by immunohistochemical staining. Results:Fourteen days and 28 days after modeling, the numbers of TUNEL positive cells, double immunofluorescence positive cells, BDNF and TrkB positive cells were significantly more in the model group than in the sham operation group (t > 27.214, P < 0.001), while the numbers of TUNEL positive cells, double immunofluorescence positive cells were significantly less in the enriched environment group than in the model group (t > 12.687, P < 0.001); and the number of BDNF and TrkB positive cells were significantly more in the enriched environment group than in the model group 28 days after modeling (t > 137.998, P < 0.001). Conclusion:Enriched environmental stimulation could reduce the apoptosis of hippocampal neurons, and up-regulate the expression of BDNF and TrkB proteins in the neonatal rats with hypoxic-ischemic brain damage.
ABSTRACT
It has been increasingly recognized that the presence of a healthy and diverse gut microbiota is important to the development of central nervous system and emotional processing for children with autism spectrum disorders (ASD). The interconnection of gut microbiome and brain function has significantly contributed to establishing the microbiota-gut-brain axis as an extension of the well-accepted gut-brain axis concept. The bidirectional interaction between the gut microbiota and the brain occurs through various pathways including serotonin, hypothalamus-pituitary-adrenal axis, neurotrophin, and the immune system. The microbiota-gut-brain axis has been shown to influence the behaviors associated with neuropsychiatric conditions. Modulation of this gut microbiota as a novel therapy for ASD is gaining interest. This paper summarized the status of neuropsychological microbiome, which provided evidence supporting the role of gut microbiota in modulating neuropsychological functions of the central nervous system and exploring the potential underlying mechanisms.
ABSTRACT
Objective:To observe the effects of exercise preconditioning on blood-brain barrier (BBB) permeability, and connexin 43 (Cx43) and pannexin 1 (Panx1) protein after cerebral ischemia-reperfusion injury in rats. Methods:Fifty-four male Sprague-Dawley rats were randomly divided into sham group (n = 18), model group (n = 18) and exercise preconditioning group (n = 18). The exercise preconditioning group was trained with treadmill for three weeks before modeling. The middle cerebral arteries were occluded in the model group and the exercise preconditioning group using the modified Koizumi suture. After reperfusion of 24 hours, the rats were assessed with modified Neurological Severity Score (mNSS). The permeability of BBB was observed with Evans blue (EB). The expression of Cx43 and Panx1 was detected with Western blotting and immunohistochemistry in the ischemic tissues. Results:Compared with the model group, the mNSS score decreased in the exercise preconditioning group (P < 0.05), while the Evans blue content and the expression of Cx43 and Panx1 decreased (P < 0.05), as well as the the positive areas of Cx43 and Panx1 (P < 0.05). Conclusion:Exercise preconditioning can improve the permeability of BBB in cerebral ischemia-reperfusion rats, which may associate with down-regulation of Cx43 and Panx1, to protect brain from injury.

Objective:To investigate the effects of acupuncture-rehabilitation therapy on homocysteine (Hcy) and cognitive function in patients with cognitive impairment after ischemic stroke. Methods:From July, 2017 to June, 2018, 88 patients with cognitive impairment after ischemic stroke were randomly divided into group A (n = 29, cluster needling), group B (n = 30, cognitive training) and group C (n = 29, acupuncture-rehabilitation). Their serum Hcy content was measured and they were assessed with Montreal Cognitive Assessment (MoCA) before and 30 days after treatment. Results:The serum Hcy content was the least in group C after treatment (F = 6.570, P < 0.01), with the most score of MoCA (F = 31.526, P < 0.001). Conclusion:Acupuncture-rehabilitation therapy is more effective than simple cluster needling or cognitive training for patients with cognitive impairment after ischemic stroke.
ABSTRACT
Background@#The pathogenesis of obstructive sleep apnea (OSA) remains not fully understood. This study aimed to explore the mechanism of OSA by assessing the association between the human tandem of P domains in a weak inwardly rectifying K+ channel (TWIK)-related acid-sensitive K+ channel-1 (TASK-1) gene and OSA.@*Methods@#A total of 164 patients with severe OSA and 171 patients without OSA were recruited from the Center for Hypertension of People’s Hospital of Xinjiang Uygur Autonomous Region (China) from April to December in 2016. Two single nucleotide polymorphisms (rs1275988 and rs2586886) in the TASK-1 gene were selected and genotyped using a kompetitive allele specific polymerase chain reaction genotyping system. Clinical-pathological characteristics and genotype data were compared between the severe and non-OSA groups to explore the association between TASK-1 gene polymorphism and severe OSA.@*Results@#There were no significant differences in genotype distribution, allele frequency, and the recessive and dominant model of the two selected single nucleotide polymorphisms (rs1275988 and rs2586886) between the severe and non-OSA groups in the total population (P < 0.05). However, for patients with a body mass index (BMI) ≥28 kg/m2, the distribution of genotypes and alleles, and the recessive model (GG + GA vs. AA) exhibited significant differences between the severe and non-OSA group (for genotypes: P = 0.014 and P = 0.026; for alleles: P = 0.006 and P = 0.011; for the recessive model: P = 0.005 and P = 0.009, respectively). The simple logistic regression analysis revealed that the GG genotype was a risk factor for OSA. The odds ratio (OR) and 95% confidence intervals (CI) were 4.902 (1.582–15.186, P = 0.006) for rs1275988 and 4.420 (1.422–13.734, P = 0.010) for rs2586886, respectively. In multivariate logistic regression analysis, the combination of GG genotypes of rs1275988 with BMI ≥28 kg/m2 increased the risk of severe OSA (OR = 8.916, 95% CI 4.506–17.645, P < 0.001).@*Conclusion@#Both the GG genotype of rs1275988 and GG genotype of rs2586886 in the TASK-1 gene may play as potential risk factors in obese patients with OSA.
