A Systematic Review and Meta-Analysis of Acupuncture Treatment for Oral Ulcer.

Background: Oral ulcer (OU) is a common oral mucosal disease manifested with obvious pain. In some studies, the efficacy of acupuncture in OU has been confirmed, but systematic reviews and meta-analyses for them are lacking. Our aim is to evaluate the efficacy of acupuncture in the treatment of OU. Methods: We searched the literature from eight databases from their inception to December 2021. We included randomized controlled trials of acupuncture for the treatment of oral ulcer. The meta-analysis was carried out using Review Manager 5.3 and Stata 16.0. The main outcomes were the effective rate and the recurrence rate, the secondary outcomes were the visual analogue score (VAS) and the ulcer healing time. Results: Totally, 18 studies were finally included in the meta-analysis, including 1,422 patients. In meta-analyses, we found that in comparison with Western medicine, acupuncture can improve effective rate (OR = 5.40, 95% CI: 3.40 to 8.58), reduce the ulcer recurrence rate (OR = 0.21, 95% CI: 0.13 to 0.33), and relieve the ulcer pain (MD = -2.26, 95% CI: -4.27to-0.24). In addition, compared with Western medicine, acupuncture plus Western medicine also can improve effective rate (OR = 2.95, 95% CI: 1.48 to 5.85). Compared with the Chinese medicine, the acupuncture plus Chinese medicine can improve the effective rate (OR = 8.26, 95% CI: 3.61 to 18.88) and relieve the ulcer pain (MD = -1.85, 95% CI: -2.51 to -1.19). Conclusion: Acupuncture may be more effective than Western medicine in terms of efficacy rate, and acupuncture combined with Western or Chinese medicine may have the potential to reduce the recurrence of ulcer and relieve the ulcer pain. However, due to limited evidence, higher quality and more rigorously designed clinical trials with larger sample sizes will be needed to further confirm our findings.

Knowledge Domain and Emerging Trends of Chinese Medicine in Management of Pediatric Asthma: A Scientometric Study.

OBJECTIVE: To analyze the intellectual landscape and emerging research trends of Chinese medicine (CM) in the management of pediatric asthma through a scientometric study. METHODS: Publications related to CM in the management of pediatric asthma were retrieved from the Web of Science Core Collection using relevant keywords. A scientometric study was performed using CiteSpace and VOSviewer. RESULTS: A total of 1,673 original articles and reviews from 1991 to 2019 were included in the analysis. The amount of annual publications had a gradual increase with time. USA was the major contributor both in country and institution analyses. Based on the co-citation, the published journals were grouped into 4 clusters. Keyword analysis indicated that the main hotspots were: (1) comprehensive management; (2) risk factors, mechanism, and prevalence; (3) prevention and treatment; (4) inflammation; and (5) environmental research. Lastly, we predicted that three emerging trends were quality of life promotion, immune response, and combination therapy. CONCLUSIONS: CM research in the management of pediatric asthma will maintain the current trend of steady growth. This scientometric analysis may help scientists to identify the areas of interests and future directions in the field.

[Knowledge graph characteristics of sepsis research based on scientometric study].

OBJECTIVE: To illustrate a relatively complete knowledge system (e.g., research outputs, current hotspots, and future trends) in the sepsis field and to help scholars grasp the scientific research direction or clinical focus of treatment. METHODS: The relevant literatures of sepsis during the time from 1985 to 2019 in Web of Science database were collected. Sepsis-related research contents were generated using softwares (CiteSpace 5.6.R2 and VOSviewer 1.6.13), which using data mining, information processing and knowledge map methods, to analyze the historical evolution and predict the development trend. RESULTS: A total of 8 189 papers on sepsis were published. The volume of publications were increasing yearly from 1985 to 2019, and reached the top list of 1 276 in 2019. For research contents of sepsis, it has formed the basic characteristics of sepsis which focusing on epidemiological studies and animal experiments. Through cluster analysis, the researches mainly focused on six aspects: septic rat, necrotizingenterocolitis, sepsis-associated encephalopathy, acute kidney injury (AKI), gut-derived sepsis, and inflammatory mediator. And it presented the literature characteristics that related to the injury or dysfunction of intestines, brain, liver, kidney or other organs, but the heart and lung researches were more marginal. Additionally, based on the top key words with the strongest citation bursts, it reflected that the development trend of the continuous attention hotspots with "endotoxin" or "endotoxin shock", the significant attention hotspots with "inflammation", "immunity" and "multiple organ dysfunction syndrome" (MODS), and the novel burst attention hotspots with sepsis management including "diagnosis" and "chemotherapy". CONCLUSIONS: Through the hotspots and trends visualization of sepsis, the current researches are prefer to animal experiments, epidemiology, or other basic scientific aspects. Meanwhile, the researches are mostly focusing on inflammatory reaction, immune function or organ dysfunctions. Integrating the knowledge maps of hotspots and trends, based on researches of epidemiology, diagnosis, risk factors, pathogenesis, or treatment, we predict that the future scientific topics will concentrating on childhood sepsis, organ injury mechanism or intervention relating to MODS, and integrated management of sepsis by combining traditional Chinese medicine and Western medicine.

Application of Chinese Medicine in the Management of Critical Conditions: A Review on Sepsis.

Critical care medicine is a medical specialty engaging the diagnosis and treatment of critically ill patients who have or are likely to have life-threatening organ failure. Sepsis, a life-threatening condition that arises when the body responds to infection, is currently the major cause of death in intensive care units (ICU). Although progress has been made in understanding the pathophysiology of sepsis, many drawbacks in sepsis treatment remains unresolved. For example, antimicrobial resistance, controversial of glucocorticoids use, prolonged duration of ICU care and the subsequent high cost of the treatment. Recent years have witnessed a growing trend of applying traditional Chinese medicine (TCM) in sepsis management. The TCM application emphasizes use of herbal formulation to balance immune responses to infection, which include clearing heat and toxin, promoting blood circulation and removing its stasis, enhancing gastrointestinal function, and strengthening body resistance. In this paper, we will provide an overview of the current status of Chinese herbal formulations, single herbs, and isolated compounds, as an add-on therapy to the standard Western treatment in the sepsis management. With the current trajectory of worldwide pandemic eruption of newly identified Coronavirus Disease-2019 (COVID-19), the adjuvant TCM therapy can be used in the ICU to treat critically ill patients infected with the novel coronavirus.

[Analysis of medication characteristics of traditional Chinese medicine in treating COVID-19 based on data mining].

OBJECTIVE: To analysis the medication characteristics of the prescriptions issued via open channel by the National and Provincial Health Committee and the State Administration of Traditional Chinese Medicine in treating coronavirus disease 2019 (COVID-19). METHODS: We collected the data of traditional Chinese medicine related to treatment plans published by the National and Provincial Health Committee and the State Administration of Traditional Chinese Medicine from the start of COVID-19 outbreak to February 19, 2020. The frequency analysis, cluster analysis and association analysis were performed. RESULTS: The study collected 4 national and 34 regional prevention and treatment plans, 578 items, 84 traditional Chinese formulations, 60 Chinese patent medicines, and 230 Chinese herbs. The high frequently used herbs were Liquorice, Scutellariabaicalensis, Semen armeniacaeamarae, and Gypsum. The commonly used traditional formulations included Maxing Shigan decoction, Yin Qiao powder, and Xuanbai Chengqi decoction. The Chinese patent drugs included Angong Niuhuang pill, Xuebijing injection, and Lianhua Qingwen capsule. The most common paired medications were Ephedra and Semen armeniacaeamarae, Fructusforsythiae and Liquorice. Two core combinations and one novel formula were discovered in the study. CONCLUSIONS: Yin Qiao powder and Huopo Xialing decoction are the basic formulations for Weifen syndrome of COVID-19. In addition, Maxing Shigan decoction, Liang Ge powder, Qingwen Baidu decoction and Da Yuan decoction are the basic formulations for Qifen syndrome of COVID-19. The main medication characteristics are clearing heat, entilating lung, removing toxicity and removing turbidity. It shows that removing toxicity and eliminating evil are the prescription thought in treating epidemic disease of traditional Chinese medicine.

Efficacy of Banxia Xiexin decoction in a rat model of chronic atrophic gastritis.

OBJECTIVE: To investigate the effectiveness of Banxia Xiexin decoction (BXD) in a rat model of chronic atrophic gastritis (CAG). METHODS: Sixty 6-week-old healthy Wistar rats (30 males, 30 females) were used in the present study. A rat model of CAG was successfully established using the combined active immunization/ethanol/sodium deoxycholate method. BXD was prepared from a mixture of seven Chinese herbs, and was intragastrically administered to CAG rats at three different doses (6, 12, and 24 g·kg－1·d－1). After 24 weeks, the rats were euthanized, and gastric tissue specimens were collected. Gastric mucosal specimens were stained with hematoxylin and eosin for histological examination to evaluate the degree of inflammation and morphological changes. Immunohistochemical staining was performed to examine the mucosal expression of proliferating cell nuclear antigen. Serum gastrin levels were measured using radioimmunoassay. The expression of Notch signaling-associated genes was examined by quantitative polymerase chain reaction and Western blot assay. RESULTS: BXD at all three doses significantly reversed the adverse effects generated by CAG in rats. Compared with control rats, the CAG rats who were administered BXD had an accelerated growth rate, reduced inflammatory cell infiltration, improved gastric mucosal morphology, augmented thickness of the gastric mucosa, increased number of gastric glands, enhanced mucosal expression of proliferating cell nuclear antigen, and elevated serum gastrin levels. CONCLUSION: BXD has a therapeutic effect in a rat model of CAG by targeting the Notch signaling pathway, thereby blocking the CAG from progressing to early gastric cancer.

Common 1H-MRS Characteristics in Patients With Alzheimer's Disease and Vascular Dementia Diagnosed With Kidney Essence Deficiency Syndrome: A Preliminary Study.

Context • Traditional Chinese medicine (TCM) indicates that both Alzheimer's disease (AD) and vascular dementia (VD) should be categorized as dementia and that they have a common etiology and pathogenesis under TCM classification of syndromes, such as with kidney essence deficiency syndrome (KEDS). The pathological location is mainly in the brain. However, it remains unclear whether AD and VD patients with KEDS exhibit a metabolic commonality in the same region of the brain. Objective • The study intended to investigate the metabolic characteristics of the brain using proton magnetic resonance spectroscopy (1H-MRS) in patients with AD and VD who had been diagnosed with KEDS. Design • The research team designed a pilot study, with the participants being allocated to 3 groups: (1) an AD group, (2) a VD group, and (3) a control group. All data analysis was carried out by a trained radiologist who was blinded to each participant's diagnosis. Setting • The study took place at the Tongde Hospital of Zhejiang Province (Zhejiang Sheng, China). Participants • Participants were patients at the Tongde Hospital with mild AD or VD who had been diagnosed with KEDS. The normal controls were patients' spouses or guardians with normal cognitive function. Outcome Measures • All participants underwent 1H-MRS. The N-acetyl aspartate (NAA)/myo-inositol (mI), NAA/creatine (Cr), choline (Cho)/Cr, and mI/Cr ratios were bilaterally measured in the posterior cingulate gyrus (PCG) and anterior cingulate gyrus (ACG) by the Syngo spectroscopy postprocessing package. Demographic characteristics and 1H-MRS data were assessed across the AD, VD, and normal control groups. Results • Thirteen patients with mild AD with KEDS, 15 patients with mild VD with KEDS, and 18 normal controls were recruited from May 2013 through May 2014. The AD and VD groups did not significantly differ in the NAA/mI, NAA/Cr, Cho/Cr, and mI/Cr ratios in either the PCG or the ACG, with the exception being the Cho/Cr ratio in the right ACG, for which the ratio of the AD group was significantly lower when compared with that of the VD group (P < .05). Conclusions • Mild AD and VD with KEDS showed similar patterns for the 1H-MRS on the cingulate cortex, providing evidence for a common pathogenesis for the KEDS that is associated with AD and VD, providing a modern biological basis for the philosophy of providing the same treatment for different diseases.
