Differences in Contents and Formation Methods of Clinical Questions in Chinese and Korean Clinical Practice Guidelines of Acupuncture-Moxibustion: Scoping Review.

OBJECTIVE: To analyze the differences in the needs of users and the value orientation of clinical practice guidelines (CPGs) by comparing the contents and formation methods of clinical questions in Chinese and Korean CPGs of acupuncture-moxibustion (Acup-Mox). METHODS: The full text of CPGs was systematically searched from the official websites of Chinese and Korean traditional medicine societies and Acup-Mox associations, with the topic "Acup-Mox for treating diseases" and the retrieval time up to September 28, 2022. Two researchers screened the CPGs independently, and extracted the guidelines' topics, content, quantity and formation methods of clinical questions. The quantitative data were collected by counting the frequency, and the qualitative data were classified and described by thematic analysis. RESULTS: A total of 29 guidelines were included in this study, including 20 Chinese guidelines (305 questions) and 9 Korean guidelines (223 questions). The differences lie in the aspects of content and diversity, and formation method. As for content and diversity, Chinese guidelines focused mainly on the questions related to treatment such as the operation of specific intervention (86, 28.2%), efficacy of intervention (78, 25.6%), and also involving questions in diagnosis, prevention, and prognosis. While the clinical questions in Korean guidelines were concentrated to efficacy of intervention (218, 97.8%). As for formation method, in Chinese guidelines, questions were usually collected directly from clinicians, and then determined and optimized by experts. In Korean guidelines, frequently used clinical Acup-Mox interventions would be screened first. Then the expert group would set up corresponding intervention control measures so as to form clinical questions related to treatment efficacy. CONCLUSIONS: The differences reflect the different needs of clinical practitioners, and the different aims or concepts in developing Acup-Mox guidelines between China and South Korea. Chinese guidelines emphasized promoting operation protocols and techniques of Acup-Mox for practical use, while Korean guidelines emphasized promoting the frequently used clinical intervention therapies. It is speculated that the guidelines from these two countries would play different roles in guiding clinical operation and supporting medical decision. In terms of formation methods of clinical questions, it is suggested to attach importance to optimizing process in formatting clinical questions to improve the clinical applicability of CPGs of Acup-Mox.

Discussion on Collection of Clinical Questions in International Clinical Practice Guidelines of Acupuncture-Moxibustion.

The clinical questions of acupuncture-moxibustion (Acup-Mox) guidelines are complicated, including not only the curative effect of Acup-Mox intervention measures, but also the operational elements of Acup-Mox. This paper aimed to put forward the idea and process of collecting clinical questions in developing international acupuncture clinical practice guidelines. The experience was collected and the idea of collecting clinical questions of Acup-Mox was formed through expert consultation and discussion in combination with expert opinions. Based on the characteristics of Acup-Mox discipline. This paper put forward the thinking of collecting elements of clinical questions following the intervention-population-outcome-control (I-P-O-C) inquiry process, according to the discipline of Acup-Mox. It was emphasized that in the process of collecting clinical questions, "treatable population" and "alleviable outcome indicators" for a specific Acup-Mox intervention with certain therapeutic effect should be focused on, so as to highlight the pertinence of clinical questions of Acup-Mox guidelines in terms of population and outcome elements.

Effects of very low-carbohydrate ketogenic diet on lipid metabolism in patients with type II diabetes mellitus: a meta-analysis.

Introduction: Objective: to evaluate the lipid metabolism of patients with type 2 diabetes mellitus (T2DM) after very low-carbohydrate ketogenic (VLCK) diet treatment, so as to provide an evidence-based basis for better dietary management and comprehensive treatment of diabetic patients. Methods: PubMed, Cochrane Library, Embase, and Web of Science databases were searched for randomized controlled trial about VLCK diet on lipid metabolism of T2DM up to September 2021. The data were analyzed using the Stata 15.0; standardized mean difference (SMD) was used as effect size. Results: ten articles were included in this meta-analysis. There were no significant differences between the two groups in total cholesterol (SMD = -0.07, 95 % CI: -0.06-0.20, p > 0.05), HDL (SMD = 0.13, 95 % CI: -0.05-0.31, p > 0.05) and LDL (SMD = 0.07, 95 % CI: -0.06-0.20, p > 0.05) levels after treatment. No difference was found in total cholesterol, HDL, and LDL levels between the two groups after 3, 6, and 12 months of treatment (p > 0.05). Triglyceride levels decreased after VLCK diet compared with control (SMD = -0.49, 95 % CI: -0.82 to -0.17, p = 0.003). A marked reduction of triglyceride levels was identified after 3 months of VLCK diet treatment (SMD = -0.69, 95 % CI: -1.00 to -0.38), without significant difference after 6 and 12 months. Conclusion: T2DM patients who receive a VLCK diet to lower blood glucose are not associated with increased levels of total cholesterol and LDL, and decreased levels of HDL. Additionally, this diet can achieve a short-term reduction of triglyceride levels.

No se encontraron diferencias en los niveles de colesterol total, HDL y LDL entre los dos grupos después de 3, 6 y 12 meses de tratamiento (p > 0,05). Los niveles de triglicéridos disminuyeron después de la dieta VLCK en comparación con el control. Se identificó una marcada reducción de los niveles de triglicéridos después de 3 meses de tratamiento con la dieta VLCK, sin diferencias significativas después de 6 y 12 meses. Conclusión: los pacientes con DMT2 que reciben una dieta VLCK para reducir la glucemia no se asocian a un aumento de los niveles de colesterol total y LDL, y a una disminución de los niveles de HDL.

[Analysis and thought on reaching the consensus during the development of acupuncture and moxibustion clinical practice guidelines in China].

Based on the 28 Chinese clinical practice guidelines of acupuncture and moxibustion, this study summarized and analyzed the contents related to reaching consensus during the development process. The results indicated that all the 28 guidelines reported they have used consensus in the "recommendations" section, and provided details on consensus personnel, consensus methods, consensus process and consensus materials. However, it was found that the reporting of consensus was in need of further improvement. The limitations included unclear definition and responsibilities of "expert group", obscure concept between "consensus meeting" and "expert discussion", non-rigorous process of reaching consensus when generating recommendations and lacking of detailed reporting of the consensus reaching process. As such, we suggested that future researchers should conduct researches to further standardized the consensus process when developing acupuncture and moxibustion clinical practice guidelines, so as to improve the quality and clinical applicability of guidelines．.

Impact of Video Technology on the Comprehension of Patients With First Insulin Injection and the Efficiency of Nurse Education.

This study aims to compare the effectiveness of video and paper materials used for teach-back education on the first insulin injection for patients with diabetes. The study enrolled 110 patients hospitalized for diabetes who had received education on their first insulin injection in the endocrinology department. The patients were divided into an intervention group (n = 55) and a control group (n = 55) using convenience sampling. Video materials were employed for the teach-back education of the intervention group, while paper materials were employed for the teach-back education of the control group. We compared cases who answered correctly to the common parts (selection and management of injection devices, selection and rotation of injection sites, proper use of injection angles and pinching, insulin storage, injection-related complications and their prevention, selection of the correct needle length, and safe disposal of needles after use) for the first time, the number of educational sessions and total education duration between the two groups and employed the "My View on Insulin" questionnaire to survey the two groups before and 28 days after the intervention. The intervention group had a shorter total education duration than the control group, a difference that was statistically significant (p < .001). The intervention group had more advantages over the control group in terms of rotation education at the injection site (p < .05). There was no statistically significant difference in the questionnaire scores between the two groups after the intervention (p > .05); however, both groups scored significantly higher than before the intervention, a difference that was statistically significant (p < .001). The teach-back method combined with video materials applied for educating patients on their first insulin injection could reduce the education duration by healthcare providers and improve the patients' psychological insulin resistance. The key to successfully teaching patients to self-administer insulin, and allowing them to master the steps involved, is to focus on "why" rather than "what" to do.

Identification of genes related to tipburn resistance in Chinese cabbage and preliminary exploration of its molecular mechanism.

BACKGROUND: Tipburn, also known as leaf tip necrosis, is a severe issue in Chinese cabbage production. One known cause is that plants are unable to provide adequate Ca2+ to rapidly expanding leaves. Bacterial infection is also a contributing factor. Different cultivars have varying degrees of tolerance to tipburn. Two inbred lines of Chinese cabbage were employed as resources in this research. RESULTS: We determined that the inbred line 'J39290' was the tipburn resistant material and the inbred line 'J95822' was the tipburn sensitive material based on the severity of tipburn, and the integrity of cell membrane structure. Ca2+ concentration measurements revealed no significant difference in Ca2+ concentration between the two materials inner leaves. Transcriptome sequencing technology was also used to find the differentially expressed genes (DEGs) of 'J95822' and 'J39290', and there was no significant difference in the previously reported Ca2+ uptake and transport related genes in the two materials. However, it is evident through DEG screening and classification that 23 genes are highly linked to plant-pathogen interactions, and they encode three different types of proteins: CaM/CML, Rboh, and CDPK. These 23 genes mainly function through Ca2+-CaM/CML-CDPK signal pathway based on KEGG pathway analysis, protein interaction prediction, and quantitative real-time PCR (qRT-PCR) of key genes. CONCLUSIONS: By analyzing the Ca2+ concentration in the above two materials, the transcription of previously reported genes related to Ca2+ uptake and transport, the functional annotation and KEGG pathway of DEGs, it was found that Ca2+ deficiency was not the main cause of tipburn in 'J95822', but was probably caused by bacterial infection. This study lays a theoretical foundation for exploring the molecular mechanism of resistance to tipburn in Chinese cabbage, and has important guiding significance for genetics and breeding.

[Investigation and analysis on the current situation of clinical practice guidelines for acupuncture and moxibustion at home and abroad].

To provide directional suggestions for the establishment of international clinical practice guidelines for acupuncture and moxibustion by investigating the current situation of clinical practice guidelines for acupuncture and moxibustion at home and abroad. The clinical practice guidelines were obtained by questionnaire survey, database retrieval and experts consulting. The guidelines were read carefully, and the content was analyzed. A total of 27 acupuncture-moxibustion clinical practice guidelines were retrieved, of which most of the guidelines came from China. The definition and scope of "acupuncture and moxibustion "vary according to different guidelines; and the focus of the content and the method of establishing the guidelines are quite different, so it is very necessary to unify the formulation methods of acupuncture-moxibustion clinical practice guidelines. Chinese clinical practice guidelines for acupuncture and moxibustion were characterized by taking the ancient literature as the evidence. Excavating the value of ancient literature and clinical experience of acupuncture-moxibustion experts are the key points and difficulties in the developing of clinical practice guidelines of acupuncture and moxibustion in the future.

[Consideration on existing problems in development of clinical practice guidelines for acupuncture and moxibustion in China].

To sort out the existing problems within the published 35 evidence-based acupuncture-moxibustion clinical practice guidelines (group standards) in Chinese: the development methods and the development process are not clear and strict enough; the evidence evaluation system fails to fully reflect the characteristics of acupuncture and moxibustion. Therefore, Norms for Formulation and Evaluation of the Guidelines on Clinical Practice of Acupuncture-Moxibustion, should require the guideline developers to consider the characteristics of acupuncture discipline, evaluate modern literature evidence comprehensively, and integrate ancient literature and medical experts' experience, to form proper recommendations for clinical practice. Specific requirements should be made simultaneously in the development process to make it clearer and stricter.

Long-Term Vegan Meditation Improved Human Gut Microbiota.

OBJECTIVE: Meditation has been widely used for the treatment of a variety of psychological, cardiovascular, and digestive diseases as well as chronic pain. Vegetarian diets can effectively prevent hypertension, metabolic diseases such as diabetes and obesity, and certain cancers. Meditation and vegetarian diets have been recognized as components of a healthy lifestyle and have therefore attracted more people around the world. Meditation can help regulate overall health through the neural-endocrine-immune network. Changes in dietary habits can affect the composition of the intestinal flora, which in turn affects human physiology, metabolism, nutrition, and immune function through the bacteria-intestine-brain axis. Here, we aimed to investigate the effect of long-term meditation and vegan diet on human intestinal flora. MATERIALS AND METHODS: The present study used 16S rDNA sequencing technology to detect the differences in intestinal flora between 12 healthy vegan subjects receiving long-term meditation training and 12 healthy omnivorous subjects who never received any meditation training. RESULTS: The results showed that, compared with the subjects in the omnivorous healthy control group who had never received any meditation training, the intestinal flora structure in the people who followed the long-term vegan meditation practices changed significantly. The intersection set between the results of the LEfSe analysis and the Wilcoxon rank sum test includes 14 bacterial genera. These 14 genera are defined as the dominant genera, and the AUC value was 0.92 in the ROC curve, which demonstrates that the 14 genera can be used as a biomarker to distinguish the two groups. Three beneficial bacteria genera (Bifidobacterium, Roseburia, and Subdoligranulum) were significantly enriched in the meditation group with a threshold of 4, according to the LDAs. The functional prediction of differentially enriched intestinal flora showed that the metabolism of tyrosine, propionate, niacin, and nicotinamide in the intestinal micro-organisms in the meditation group was significantly reduced compared with those in the control group, while the biosynthesis of flavones, flavone alcohols, butosin, and neomycin; flavonoid-mediated oocyte maturation; cytoskeleton protein pathways; and antigen processing and presentation were significantly enhanced. CONCLUSIONS: These results indicate that long-term vegan meditation plays a positive role in improving the body's immunity and adjusting endocrine and metabolic levels, enabling the body to be in a state of good health.

[Regulating effect of electroacupuncture on left ventricular function and autophagy-specific proteins in spontaneously hypertension rats].

OBJECTIVE: To investigate the effect of electroacupuncture (EA) on cardiac hypertrophy and expression of myocardial autophagy-specific proteins in spontaneously hypertensive rats (SHRs). METHODS: Twelve male Wistar Kyoto (WKY) rats were selected as the normal control group, and 24 male SHRs were randomized into model and EA groups (n＝12 in each). EA (2 Hz /15 Hz, 1 mA) was applied to "Taichong" (LR3) and "Baihui" (GV20) for 20 min, once a day for successive 30 days. The other two groups only received the same grasping and fixation procedures. The systolic blood pressure (SBP) was measured using a non-invasive blood detector, and the left ventricular function including the left ventricular anterior wall diameter (LVAWd), left ventricular posterior wall diameter (LVPWd) and left ventricular internal diameter at end-diastolic dimension (LVIDd) was detected using a real-time echocardiography imaging system, and the left ventricular mass index (left ventricle weight / body weight, LVMI) was calculated. The expression of Beclin-1 and LC3 proteins in the left ventricle tissue was detected by Western blot. Pathological changes of the myocardial tissue were observed by Masson staining and transmission electron microscope (TEM). RESULTS: After the intervention, the elevated SBP was significantly lowered in the EA group relevant to the model group (P<0.01) and the increased LVAWd, LVPWd and LVMI were markedly decreased in the EA group (P<0.01, P<0.05), while the reduced LVIDd was significantly ameliorated in the EA group (P<0.01). Masson staining showed that in SHRs, disorder of arrangement of cardiac myofibers, swelling of cardiomyocytes, widened space among myocardial cells with a large number of collagenous fibers were observed, and under TEM, aggregation and unequal size of myocardial mitochondria with vacuolation and rupture, autophagosomes and autophagic lysosomes were seen. These changes were relatively milder in the EA group. Western blot showed that hypertension induced up-regulation of Beclin-1 and LC3-II and ratio of LC3-II/LC3-I, and down-regulation of LC3-I were significantly suppressed in the EA group (P<0.01, P<0.05). CONCLUSION: EA at LR3 and GV20 may improve the left cardiac function, myocardial morphological changes and the degree of autophagy in SHRs, which is related to its effects in down-regulating the expression of myocardial Beclin-1 and LC3-II and in up-regulating expression of LC3-I.

[Progress of the application of PET technology in acupuncture research].

To further investigate the application of positron emission tomography (PET) technology in acupuncture research field, with "PET" and "acupuncture" as keywords, the related literature published from 1997 to 2018 was searched in PubMed, CNKI and WANFANG database; then the literature was classified and analyzed. The results showed that in clinical and experimental studies, whether in physiological or pathological conditions, PET technology has verified the specificity of acupoints, bidirectional regulation of acupoints, and the clinical effect of qi-arrival from the level of brain functional activity. It has deeply revealed the central mechanism underlying that acupuncture has multi-target, multi-channel and multi-level overall effects. The purpose of this study is to provide objective scientific basis for acupuncture research, and then potentially guide the clinical practice.

Welltang - A smart phone-based diabetes management application - Improves blood glucose control in Chinese people with diabetes.

AIMS: The primary objective was to evaluate the impact of the smart phone-based diabetes management application, Welltang, on glycated hemoglobin (HbA1c). The second objective was to measure whether Welltang improves blood glucose, low-density lipoprotein cholesterol, weight, blood pressure, hypoglycemic events, satisfaction of patients to use Welltang, diabetes knowledge of patients, and self-care behaviors. METHODS: One hundred evenly randomized subjects with diabetes, aged 18-74years, were recruited from the outpatient Department of Endocrinology for a 3-month study. The Welltang intervention group received training for the use of Welltang, while the control group received their usual standard of care. HbA1c, blood glucose, low-density lipoprotein cholesterol, weight, blood pressure, hypoglycemic events, satisfaction of patients to use Welltang, diabetes knowledge of patients, and self-care behaviors were measured. Patient data were analyzed using independent t test and paired sample test using SPSS version 12. RESULTS: The average decrease in HbA1c was 1.95% (21mmol/mol) in the intervention group and 0.79% (8mmol/mol) in the control group (P<0.001). Measures of self-monitored blood glucose, diabetes knowledge, and self-care behaviors improved in patients in the intervention group. Eighty four percent of patients in the intervention group were satisfied with the use of Welltang. Differences in hypoglycemic events, low-density lipoprotein cholesterol, weight, and blood pressure were not statistically significant. CONCLUSION: Diabetes patients using the Welltang application achieved statistically significant improvements in HbA1c, blood glucose, satisfaction of patients to use of Welltang, diabetes knowledge, and self-care behaviors.

Can the upper inner side of the thigh become a new option for insulin injection?

OBJECTIVE: Sites for subcutaneous insulin injections include the upper arms, abdomen, buttocks and outer sides of the thigh. No similar study has explored the feasibility of using the inner side of the thigh for insulin injection, since the 4 mm pen needles were introduced for clinical use. This study aimed to determine whether the inner side of the thigh is suitable for insulin injection. RESEARCH DESIGN AND METHODS: Seventy-five patients with diabetes under insulin therapy from the Inpatient Department of Endocrinology were recruited for this non-blinded, non-randomized observational study. Subcutaneous adipose layer thicknesses of the upper, middle and lower area of the inner and outer thighs of 35 patients were measured by ultrasound, distance from the skin surface to the femoral deep vessels in 20 patients was measured, and insulin was injected at the upper inner and outer sides of the thigh in 20 patients. Pain perception, bleeding or bruising, leakage at the injection sites, blood glucose changes after insulin injection, and preferred ratings of the patients were measured. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT02307968. RESULTS: Subcutaneous adipose layer thicknesses at both the upper inner and outer thighs were more than 4 mm and the minimum distance was 10 mm. Among the 100 injections at the upper inner thigh, only three incidents of perceived pain occurred. No bleeding or bruising and leakage were observed from the inner or outer sides. Furthermore, the difference in blood glucose control between insulin injections at the inner side and outer sides was not statistically significant. Patient ratings for injections at the inner side were similar to injections at the outer side. The key limitation of this study was the small sample size of adult patients as well as the non-randomized controlled design of this study. CONCLUSION: The upper inner thigh might be a new option for insulin injection rotation.
