Objective:To investigate the impact of immunosuppressive therapy on the severity of SARS-CoV-2 infection and cytokine levels in pediatric patients with kidney diseases.Methods:A retrospective analysis was conducted on the clinical data of 40 hospitalized pediatric patients who were diagnosed with SARS-CoV-2 infection at the 900th Hospital of PLA Joint Logistic Support Force from December 2022 to February 2023. Based on their immunosuppressive status prior to SARS-CoV-2 infection, these patients were categorized into immunosuppressive group and non-immunosuppressive group. Independent sample t-tests, Mann-Whitney U tests, and χ2 test were employed to compare the clinical baseline characteristics and laboratory data, the severity of SARS-CoV-2 infection, and the levels of cytokines between the 2 groups. Results:Among the 40 patients, 11 were in the immunosuppressive group (aged 13 (8, 14) years, 9 males and 2 females) and 29 in the non-immunosuppressive group (aged 2 (1, 4) years, 15 males and 14 females). In the immunosuppressive group, 2 were asymptomatic cases, 8 were mild cases, and 1 was moderate case, and there was no severe or critical cases. In the non-immunosuppressive group, 8 were mild cases, 5 were moderate, 15 were severe cases, 1 was critical case, and no asymptomatic cases. The underlying diseases in the immunosuppressive group included nephrotic syndrome (6 cases), IgA vasculitis nephritis (2 cases), lupus nephritis (1 case), post-renal transplantation (1 case), and renal failure (1 case), with a mean total immunosuppression score (TIS) of (3.6±1.4) points. In the non-immunosuppressive group, 2 patients had a history of epilepsy, and the remaining 27 cases had no underlying conditions, all with TIS scores of 0. Compared to the children in the non-immunosuppressive group, those in the immunosuppressive group were more likely to exhibit asymptomatic or mild infection, with lower risks of severe disease, cytokine storm, fever, and cough, but a higher risk of fatigue ( OR=1.22, 2.66, 0.48, 0.12, 0.12, 0.13, 1.22; 95% CI 0.93-1.62, 0.99-7.15, 0.33-0.70, 0.03-0.57, 0.03-0.57, 0.03-0.65, 0.93-1.62; all P<0.05). The levels of cytokine IL-6, interferon-α and interferon-γ in the immunosuppressive group were all lower than those in the non-immunosuppressive group ( Z=2.23, 2.51, 2.92, respectively; all P<0.05). Conclusion:Pediatric patients with kidney diseases receiving appropriate immunosuppressive therapy may mitigate the severity of SARS-CoV-2 infection by suppressing the expression of cytokines.

OBJECTIVE: To explore the research history, hotspots and development trends of acupuncture and moxibustion in the treatment of gastroesophageal reflux disease（GERD）based on knowledge graph technology, and to provide references for clinical and basic research in this field. METHODS: The literature of acupuncture and moxibustion for gastroesophageal reflux disease was searched from the CNKI, Wanfang, VIP and SinoMed, from the establishment of the databases to December 31th, 2023. CiteSpace 6.2.R6 Advance was used to draw the knowledge graph of authors, institutions, keywords and other elements, and then perform the visual analysis. RESULTS: A total of 341 articles were included, with the number of publications showing an upward trend and the research types continually diversifying. A total of 832 authors and 308 institutions were analyzed, with XIE Sheng from the First Affiliated Hospital of Guangxi University of CM and BAI Xinghua from the Beijing University of CM as representative figures, forming core research teams. However, there was a lack of close collaboration between institutions, and no significant cross-regional research networks had been formed. A total of 192 keywords were included, forming 8 cluster labels, which mainly included 4 categories：treatment methods, disease types, TCM syndrome types, and literature types. The burst analysis showed that the methods of acupuncture and moxibustion in the treatment of gastroesophageal reflux disease had gradually become more integrated, the treatment methods had transitioned from simple acupuncture therapy to combined therapies with proton pump inhibitors or TCM decoctions, the disease types had become more refined, the focus of mechanism research had shifted from lower esophageal sphincter pressure and esophageal motility to changes in gastrointestinal hormone levels, and the research hotspots had gradually shifted from improving clinical symptoms to considering both mental and psychological states. Twenty-three high-frequency acupoints were obtained, forming 8 clusters of "acupuncture techniques-acupoints" for the treatment of gastroesophageal reflux disease with acupuncture and moxibustion, indicating a gradual enrichment of acupuncture and acupoint treatment protocols. CONCLUSION The research on acupuncture and moxibustion in the treatment of gastroesophageal reflux disease has gradually deepened, in the future, the cooperation among research teams should be strengthened, the quality of clinical research should be improved, more multi-dimensional mechanism research and horizontal comparative research of different acupuncture and moxibustion methods should be made, to provide a basis for clinical promotion and deeper exploration.

Objective To conduct a visual analysis of the current status, hotspots, and frontiers of research on renal cell carcinoma targeted therapy using VOSviewer software. Methods Literature related to renal cell carcinoma targeted therapy published between January 1, 2006 and December 31, 2023, from the Web of Science (WOS) Core Collection database were retrieved. Eligible articles were screened and subjected to bibliometric and visual analysis using VOSviewer software. Results A total of 1, 009 articles were selected, with an overall increasing trend in annual publication volume. The top three countries in terms of publication output were the United States, China, and Italy, while the top three institutions were Harvard University, The University of Texas, and France Uni-cancer Institute. The analysis of the core author collaboration network revealed close collaboration among researchers in the United States and the United Kingdom, whereas collaboration between China and foreign countries was limited, resulting in a relatively loose collaboration network. Through co-occurrence clustering analysis of high-frequency author keywords, nine clusters were generated, with hotspots focusing on targeted and immune combination therapy, efficacy, prognosis, drug resistance, targets, and biomarkers. Conclusion Remarkable progress has been made in renal cell carcinoma targeted therapy research over the past decade; however, drug resistance and adverse reactions to targeted therapies remain challenges in clinical treatment. Research related to targeted drug resistance mechanisms, novel targeted drugs, and effective predictive biomarkers has significantly increased. Grasping the developmental trends in this fieldis crucial, and VOSviewer's visual analysis can offer an intuitive representation of the current status, hotspots, and frontiers, thereby providing researchers with a valuable reference.

Transcranial magneto-acoustic electrical stimulation (TMAES) is a novel method of brain nerve regulation and research, which uses induction current generated by the coupling of ultrasound and magnetic field to regulate neural electrical activity in different brain regions. As the second special envoy of nerve signal, calcium plays a key role in nerve signal transmission. In order to investigate the effect of TMAES on prefrontal cortex electrical activity, 15 mice were divided into control group, ultrasound stimulation (TUS) group and TMAES group. The TMAES group received 2.6 W/cm ² and 0.3 T of magnetic induction intensity, the TUS group received only ultrasound stimulation, and the control group received no ultrasound and magnetic field for one week. The calcium ion concentration in the prefrontal cortex of mice was recorded in real time by optical fiber photometric detection technology. The new object recognition experiment was conducted to compare the behavioral differences and the time-frequency distribution of calcium signal in each group. The results showed that the mean value of calcium transient signal in the TMAES group was (4.84 ± 0.11)% within 10 s after the stimulation, which was higher than that in the TUS group (4.40 ± 0.10)% and the control group (4.22 ± 0.08)%, and the waveform of calcium transient signal was slower, suggesting that calcium metabolism was faster. The main energy band of the TMAES group was 0-20 Hz, that of the TUS group was 0-12 Hz and that of the control group was 0-8 Hz. The cognitive index was 0.71 in the TMAES group, 0.63 in the TUS group, and 0.58 in the control group, indicating that both ultrasonic and magneto-acoustic stimulation could improve the cognitive ability of mice, but the effect of the TMAES group was better than that of the TUS group. These results suggest that TMAES can change the calcium homeostasis of prefrontal cortex nerve clusters, regulate the discharge activity of prefrontal nerve clusters, and promote cognitive function. The results of this study provide data support and reference for further exploration of the deep neural mechanism of TMAES.

Chronic high-salt diet-associated renal injury is a key risk factor for the development of hypertension. However, the mechanism by which salt triggers kidney damage is poorly understood. Our study investigated how high salt (HS) intake triggers early renal injury by considering the ‘gut-kidney axis’. We fed mice 2% NaCl in drinking water continuously for 8 weeks to induce early renal injury. We found that the ‘quantitative’ and ‘qualitative’ levels of the intestinal microflora were significantly altered after chronic HS feeding, which indicated the occurrence of enteric dysbiosis. In addition, intestinal immunological gene expression was impaired in mice with HS intake. Gut permeability elevation and enteric bacterial translocation into the kidney were detected after chronic HS feeding. Gut bacteria depletion by non-absorbable antibiotic administration restored HS loading-induced gut leakiness, renal injury and systolic blood pressure elevation. The fecal microbiota from mice fed chronic HS could independently cause gut leakiness and renal injury. Our current work provides a novel insight into the mechanism of HS-induced renal injury by investigating the role of the intestine with enteric bacteria and gut permeability and clearly illustrates that chronic HS loading elicited renal injury and dysfunction that was dependent on the intestine.

Objective To observe the effect of electroacupuncture on early enteral nutrition (EEN) support in patients with severe craniocerebral injury.Methods A prospective, randomized, controlled study was conducted, 50 patients with severe craniocerebral injury admitted to the the Department of Intensive Care Unit of Traditional Chinese Medicine Hospital of Ningbo from January 2014 to October 2016 were enrolled, and they were randomly divided into electroacupuncture experimental group (26 cases) and conventional treatment control group (24 cases) by randome number table. Enteral nutrition (EN) support was implemented in 24 - 48 hours after admission for all the patients, additionally, the electroacupuncture experimental group was treated by electroacupuncture stimulating acupoint from the 1st day after admission, once 30 minutes daily for consecutive 10 days. The levels of EN calorie reaching standard situation and the parenteral nutrition (PN) necessary for addition were recorded on 3 days and 5 days after admission; the nasal feeding amount of the two groups was recorded on the 1, 4, 7 days; the incidences of complications during EN support period were observed in both groups.Results The proportion of EN calorie reaching the standard in electroacupuncture experimental group was significantly higher than that in the conventional treatment control group in 5 days of treatment [92.3% (24/26) vs. 70.8% (17/24),P < 0.05]. The proportions necessary for addition of PN support were lower in electroacupuncture experimental group than those in the conventional treatment control group on 3 days and 5 days of treatment [3 days: 19.2% (5/26) vs. 25.0% (6/24), 5 days: 7.7% (2/26) vs. 16.7% (4/24)], but there were no significant statistical differences between the two groups (bothP > 0.05). The nasal feeding amounts in electroacupuncture experimental group were significantly higher than those in the conventional treatment control group on 4 days and 7 days of treatment [4 days (mL): 1292.31±123.04 vs.1204.17±139.81,7 days (mL):1342.31±113.75 vs.1275.00±103.21, bothP < 0.05]. The incidence of complications of the electroacupuncture experimental group was significantly lower than that of the conventional treatment control group in 10 days of treatment [26.92% (7/26) vs. 41.67% (10/24),P < 0.05].Conclusions Application of electroacupuncture has a certain clinical value during implementing EN support for treatment of patients with severe craniocerebral injury, early intervention of electroacupuncture can effectively improve the patients' gastrointestinal function and elevate the successful rate of EN, and the therapy is simple, effective and safe without any obvious adverse reactions.
