Evaluation of cutout factors with small and narrow fields using various dosimetry detectors in electron beam keloid radiotherapy.

BACKGROUND: The inherent problems in the existence of electron equilibrium and steep dose fall-off pose difficulties for small- and narrow-field dosimetry. OBJECTIVE: To investigate the cutout factors for keloid electron radiotherapy using various dosimetry detectors for small and narrow fields. METHOD: The measurements were performed in a solid water phantom with nine different cutout shapes. Five dosimetry detectors were used in the study: pinpoint 3D ionization chamber, Farmer chamber, semiflex chamber, Classic Markus parallel plate chamber, and EBT3 film. RESULTS: The results demonstrated good agreement between the semiflex and pinpoint chambers. Furthermore, there was no difference between the Farmer and pinpoint chambers for large cutouts. For the EBT3 film, half of the cases had differences greater than 1%, and the maximum discrepancy compared with the reference chamber was greater than 2% for the narrow field. CONCLUSION: The parallel plate, semiflex chamber and EBT3 film are suitable dosimeters that are comparable with pinpoint 3D chambers in small and narrow electron fields. Notably, a semiflex chamber could be an alternative option to a pinpoint 3D chamber for cutout widths≥3 cm. It is very important to perform patient-specific cutout factor calibration with an appropriate dosimeter for keloid radiotherapy.

Percutaneous Coronary Intervention-Related Radiation Ulcer: Diagnosis, Management, and Prevention Strategy.

Background: Radiation ulcers after percutaneous coronary intervention (PCI) are increasingly common. However, their diagnosis, treatment, and prevention strategies have not been well studied. Objectives: To present our experience in the diagnosis, treatment, and prevention of PCI-related radiation ulcers. Methods: Patients diagnosed with PCI-related radiation ulcers were collected. Radiation fields of PCI were simulated using the Pinnacle treatment planning system to confirm the diagnosis. Surgical methods and outcomes were reviewed, and a prevention protocol was developed and evaluated for its effectiveness. Results: Seven male patients with ten ulcers were included. Among the patients, the right coronary artery was the most common target vessel of PCI, and the left anterior oblique was the most commonly used PCI view. Nine ulcers had undergone radical debridement and reconstruction: four smaller ones with primary closure or local flaps, and five with thoracodorsal artery perforator flaps. No new cases were identified in a 3-year follow-up period after implementing the prevention protocol. Conclusions: PCI-related ulcer diagnosis is more evident with radiation field simulation. The thoracodorsal artery perforator flap is an ideal option for back or upper arm radiation ulcer reconstruction. The proposed prevention protocol for PCI procedures was effective in lowering the incidence of radiation ulcers.

Psychometrics and measurement invariance: Health Literacy Scale for Vietnamese and Indonesian married immigrants.

AIMS: To examine the psychometrics and measurement invariance of the Short-Form Health Literacy 12-item questionnaire (HL-SF12) among Vietnamese and Indonesian married immigrants. DESIGN: A cross-sectional survey design. METHODS: In total, 1171 Vietnamese and Indonesian married immigrants were enrolled between September 2019 and December 2019. An exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to verify the structural validity of the suggested factor structure. The multiple-group CFA (MGCFA) used a series of hierarchical nested-in models as a measurement invariance test which confirmed the adequacy of the model fit at each stage. RESULTS/FINDINGS: The Kaiser-Meyer-Olkin coefficient was 0.898, and the Bartlett test of sphericity was statistically significant (χ2 [66] = 1965.97, p < 0.01). According to a scree plot and Kaiser's criterion for eigenvalues of >1, the EFA explained 61.6% of the total variance and confirmed three theoretically supported factors of health care, disease prevention and health promotion. The 12 items showed factor loadings of >0.4 and four items were in each subscale. The CFA showed adequate structural validity, including a relative chi-squared/degrees of freedom (X2 /df) of 2.01, a comparative fit index (CFI) of 0.98 and a root mean square error of approximation (RMSEA) of 0.04 (95% confidence interval [0.03, 0.05]) in married immigrants. For the measurement invariance, a change in the goodness-of-fit measures did not exceed 0.02 for the RMSEA or 0.01 for the CFI. The results indicated Cronbach's α values of 0.87 for the HL-SF12 scale in Vietnamese and Indonesian combined samples (n = 1171). A t-test showed that the HL-SF12 and its three subscales were unable to significantly differentiate between Vietnamese and Indonesian groups (all p > 0.05). CONCLUSIONS: The HL-SF12 scale showed acceptable theoretically supported structural validity, equivalent measurement invariance and reliable internal consistency among Vietnamese and Indonesian married immigrants. Measurements of immigrants' HL using the HL-SF12 could be integrated into future immigrant health policies. IMPACT: As the first study of the measurement invariance of the HL-SF12 instrument among immigrants. Related factors of immigrants' HL can be further explored to increase immigrants' health and empowerment.

Aspartame Consumption, Mitochondrial Disorder-Induced Impaired Ovarian Function, and Infertility Risk.

Frequent consumption of diet drinks was associated with oocyte dysmorphism, decreased embryo quality, and an adverse effect on pregnancy rate. We investigated the harmful effects of aspartame and potential mechanisms through which it increases infertility risk through clinical observations and in vivo and in vitro studies. Methods: We established a cohort of 840 pregnant women and retrospectively determined their time to conceive. We assessed the estrus cycle, the anti-Mullerian hormone level, ovarian oxidative stress, and ovarian mitochondrial function in an animal study. We also evaluated mitochondria function, mitochondrial biogenesis, and progesterone release with in vitro studies. Aspartame consumption was associated with increased infertility risk in the younger women (Odds ratio: 1.79, 95% confidence interval: 1.00, 3.22). The results of the in vivo study revealed that aspartame disrupted the estrus cycle and reduced the anti-Mullerian hormone level. Aspartame treatment also suppressed antioxidative activities and resulted in higher oxidative stress in the ovaries and granulosa cells. This phenomenon is caused by an aspartame-induced decline in mitochondrial function (maximal respiration, spare respiratory capacity, and ATP production capacity) and triggered mitochondrial biogenesis (assessed by examining the energy depletion signaling-related factors sirtuin-1, phosphorylated adenosine monophosphate-activated protein kinase, peroxisome proliferator-activated receptor-gamma coactivator-1α, and nuclear respiratory factor 1 expression levels). Aspartame may alter fertility by reserving fewer follicles in the ovary and disrupting steroidogenesis in granulosa cells. Hence, women preparing for pregnancy are suggested to reduce aspartame consumption and avoid oxidative stressors of the ovaries.

Renoprotective effect of oral rehydration solution III in exertional heatstroke rats.

AIM: Exertional heastroke (EHS) can lead to acute kidney injury. Oral rehydration solution III (ORS III), recommended by WHO in 2004, is used to rehydrate children with gastroenteritis. This study aimed to characterize the renoprotective effect of ORS III in EHS rats. METHODS: Rats were randomly divided into Group Control, Group EHS, Group EHS + Water, and Group EHS + ORS. Thirty minutes before the experiment, ORS III was orally administrated to Group EHS + ORS, Water was given to Group EHS + Water. Rats from Group EHS, Group EHS + Water and Group EHS + ORS were then forced to run until they fatigued. Core temperature (Tc) was monitored and 40.5 °C was considered as the onset of heatstroke. Serum creatinine (SCr), blood urea nitrogen (BUN) were measured using an automated biochemical analyzer. Serum neutrophil gelatinase-associated lipocalin (NGAL) was measured using an NGAL ELISA Kit. Light microscopy was used for kidney structural analysis. RESULTS: SCr level in Group EHS was no different from Group Control (p > .05), while BUN and NGAL levels in Group EHS were higher than Group Control (p <.001, p < .001). SCr, BUN and NGAL concentrations in group EHS + Water were no different from Group EHS (p > .05). SCr, BUN levels in Group EHS + ORS were no different from Group EHS (p > .05). But NGAL levels were significant in these two groups (p = .012). Renal histopathologies of rats in Group EHS and Group EHS + Water showed flattened lumens filled with eosinophilic materials. The damage was milder in Group EHS + ORS, in which injured tubules showed degeneration of the tubular epithelium and sloughing of the brush border membrane. CONCLUSION: ORS III could alleviate the kidney injury in EHS rats.

[Effects of TimeSlips on Depressive Symptoms and Quality of Life in People With Dementia in Day Care Centers].

BACKGROUND: Day care centers provide supportive services to older individuals with disability and dementia. Those who suffer from cognitive impairment typically also suffer from depression. PURPOSE: To explore whether TimeSlips, a reminiscence creative storytelling approach, improves depressive symptoms and quality of life (QoL) in older individuals of day care centers who have mild to moderate cognitive impairment. METHODS: A randomized non-blind controlled trial design was conducted. A total of 20 older individuals who met the inclusion criteria were recruited and randomly assigned to the experimental group and control group using the Internet randomization system, with 10 subjects in each group. The experimental group participated in the one-hour TimeSlips intervention once a week for six consecutive weeks, while the control group maintained their normal daily activities. We used the Cornell Scale for Depression in Dementia (CSDD) to measure depressive symptoms and used EQ-5D (EuroQol-5 dimensions) VAS (visual analogue scale) and utility values to measure QoL. RESULTS: (1) With the exception of age, there were no significant differences in the demographic data between two groups. (2) Under ANCOVA, when age was used as the covariate and the change in CSDD before and after the intervention was used as the dependent variable, the score of the experimental group was significant lower than that of the control group (p < .05). The interaction between group and age was also a significant difference in the change of CSDD before and after the intervention (p < .05). In terms of QoL, the EQ-5D VAS and EQ-5D utility value both decreased after the intervention in the experimental group. ANCOVA was performed separately using the change of EQ-5D VAS and the ranked change of EQ-5D utility values as dependent variables, with no significant differences found between the groups (p = .37 and p = .20, respectively). CONCLUSIONS: The results indicate that using TimeSlips may significantly improve depressive symptoms in mild to moderate cognitively impaired older individuals of day care centers. However, no evidence was found to support an effect of TimeSlips on QoL. Our findings provide information to help day care centers staffs design related activities.

Metabolic correlates of health-related quality of life among overweight and obese adolescents.

BACKGROUND: Little is known about the metabolic factors associated with the health-related quality of life (HRQOL) among obese youths. The aim of this study is to assess metabolic correlates of HRQOL in a clinical sample of Taiwanese overweight and obese (OW/OB) adolescents. METHODS: OW/OB adolescents (age 11-19 years) were recruited and compared to their normal-weight counterparts in a tertiary hospital. HRQOL was assessed by the Pediatric Quality of Life Inventory (PedsQL). Student t tests and Cohen's d were used to compare the differences in the PedsQL scores between normal-weight and OW/OB participants who were stratified by their cumulative number of cardiometabolic risk factors (CRF). Pearson's correlation and multivariate linear regression analyses were applied to identify predictors of PedsQL. RESULTS: OW/OB adolescents (n = 60) reported lower PedsQL scores than those of normal-weight peers. The negative effects were even larger in OW/OB participants with more than one CRF. Body mass index z-scores and serum alanine aminotransferase (ALT) levels were negatively correlated with overall and subscales of PedsQL (r = - 0.283 to - 0.431). Multivariate linear models showed ALT to be the most salient factor associated with poor obesity-related HRQOL. CONCLUSION: Taiwanese OW/OB adolescents, particularly those having additional CRF, reported worse HRQOL. Impaired liver functions may predispose OW/OB subjects to even worse HRQOL.

Osseous wound repair under inhibition of the axis of advanced glycation end-products and the advanced glycation end-products receptor.

BACKGROUND/PURPOSE: Blockade of advanced glycation end-products (AGE) is able to reduce diabetic complications and control periodontitis. This study aimed to determine whether the application of aminoguanidine (AG), an AGE inhibitor, or N-phenacylthiazolium bromide (PTB), an AGE breaker, facilitates the healing of an osseous wound in non-diabetic animals. METHODS: 2.6 mm diameter full-thickness osseous wounds were created bilaterally in 54 healthy Sprague-Dawley rats. Rats received daily normal saline, AG, or PTB injections respectively and were euthanized after 7 days, 14 days, or 28 days (n = 6). The wound healing pattern was assessed by micro-computed tomography, histology, histochemistry for the fiber arrangement, and the gene expression levels of AGE receptor, tumor necrosis factor-α, type I collagen, and fibronectin. RESULTS: Under the AG and PTB administration, osteogenesis was apparently promoted in the early stages of healing, but the union of the osseous wound and the fibril re-arrangement was apparently retarded. No significant difference was found in any of the micro-computed tomography parameters as compared to the control in the first 14 days, whereas the relative bone volume was significantly higher in the control at Day 28. AGE receptor and tumor necrosis factor-α were depressed in the PTB group, but only temporarily at Day 14 in the AG group. Therefore, at Day 14, type I collagen was significantly upregulated in the PTB group, and fibronectin was significantly increased in the AG group. CONCLUSION: Anti-AGE agents reduced inflammation but did not apparently facilitate osteogenesis during the osseous wound repair.

Activation of open-cage fullerenes with ruthenium carbonyl clusters.

Reactions of the open-cage fullerene C63NO2(Py)(Ph)2 (1) with [Ru3(CO)12] produce [Ru3(CO)8(µ,η(5)-C63NO2(Py)(Ph)2)] (2), [Ru2H(CO)3(µ,η(7)-C63N(Py)(Ph)(C6H4))] (3), and [Ru(CO)(Py)2(η(3)-C63NO2(Py)(Ph)2)] (4), in which the orifice sizes are modified from 12 to 8, 11, and 15-membered ring, through ruthenium-mediated C-O and C-C bond activation and formation.

Serum hyperglycemia might be not related to fat composition of diet and vegetable composition of diet might improve sugar control in taiwanese diabetic subjects.

OBJECTIVE: This is an Asian study, which was designed to examine the correlations between biochemical data and food composition of diabetic patients in Taiwan. METHODS: One hundred and seventy Taiwanese diabetic patients were enrolled. The correlations between biochemical data and diet composition (from 24-hour recall of intake food) of these patients were explored (Spearman correlation, p < 0.05). Diet components were also correlated with each other to show diet characteristics of diabetic patients in Taiwan. Linear regression was also performed for the significantly correlated groups to estimate possible impacts from diet composition to biochemical data. RESULTS: Postprandial serum glucose level was negatively correlated with fat percentage of diet, intake amount of polyunsaturated fatty acid and fiber diet composition. Hemoglobin A1c was negatively correlated with fat diet, polyunsaturated fatty acid and vegetable diet. Fat composition, calorie percentage accounted by polyunsaturated fatty acid and monounsaturated fatty acid in diet seemed to be negatively correlated with sugar percentage of diet and positively correlated with vegetable and fiber composition of diet. Linear regression showed that intake amount of polyunsaturated fatty acid, calorie percentage accounted by polyunsaturated fatty acid, fat percentage of diet, vegetable composition of diet would predict lower hemoglobin A1c and postprandial blood sugar. Besides, higher percentage of fat diet composition could predict higher percentage of vegetable diet composition in Taiwanese diabetic patients. CONCLUSION: Fat diet might not elevate serum glucose. Vegetable diet and polyunsaturated fatty acid diet composition might be correlated with better sugar control in Taiwanese diabetic patients.

Przewaquinone A inhibits Angiotensin II-induced endothelial diastolic dysfunction activation of AMPK.

BACKGROUND: Endothelial dysfunction (ED), characterized by markedly reduced nitric oxide (NO) bioavailability, vasoconstriction, and a shift toward a proinflammatory and prothrombotic state, is an important contributor to hypertension, atherosclerosis, and other cardiovascular diseases. Adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) is widely involved in cardiovascular development. Przewaquinone A (PA), a lipophilic diterpene quinone extracted from Salvia przewalskii Maxim, inhibits vascular contraction. PURPOSE: Herein, the goal was to explore the protective effect of PA on ED in vivo and in vitro, as well as the underlying mechanisms. METHODS: A human umbilical vein endothelial cell (HUVEC) model of ED induced by angiotensin II (AngII) was used for in vitro observations. Levels of AMPK, endothelial nitric oxide synthase (eNOS), vascular cell adhesion molecule-1 (VCAM-1), nitric oxide (NO), and endothelin-1 (ET-1) were detected by western blotting and ELISA. A mouse model of hypertension was established by continuous infusion of AngII (1000 ng/kg/min) for 4 weeks using osmotic pumps. Following PA and/or valsartan administration, NO and ET-1 levels were measured. The levels of AMPK signaling-related proteins in the thoracic aorta were evaluated by immunohistochemistry. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were measured using the tail cuff method. Isolated aortic vascular tone measurements were used to evaluate the vasodilatory function in mice. Molecular docking, molecular dynamics, and surface plasmon resonance imaging (SPRi) were used to confirm AMPK and PA interactions. RESULTS: PA inhibited AngII-induced vasoconstriction and vascular adhesion as well as activated AMPK signaling in a dose-dependent manner. Moreover, PA markedly suppressed blood pressure, activated vasodilation in mice following AngII stimulation, and promoted the activation of AMPK signaling. Furthermore, molecular simulations and SPRi revealed that PA directly targeted AMPK. AMPK inhibition partly abolished the protective effects of PA against endothelial dysfunction. CONCLUSION: PA activates AMPK and ameliorates endothelial dysfunction during hypertension.

This article provides current useful medical information on IM for COVID-19 care which could benefit APEC economies and world health communities on their healthcare system.

Flexibilisquinone, a new anti-inflammatory quinone from the cultured soft coral Sinularia flexibilis.

A new quinone derivative, flexibilisquinone (1), was isolated from the cultured soft coral Sinularia flexibilis, originally distributed in the waters of Taiwan. The structure of quinone 1 was established by extensive spectroscopic methods, particularly 1D and 2D NMR experiments. In the in vitro anti-inflammatory effects test, quinone 1 was found to significantly inhibit the accumulation of the pro-inflammatory iNOS and COX-2 proteins of the LPS-stimulated RAW264.7 macrophage cells.

Whole-Exome Sequencing Identified Rare Genetic Variants Associated with Undervirilized Genitalia in Taiwanese Pediatric Patients.

Disorders/differences of sex development (DSDs) are a group of rare and phenotypically variable diseases. The underlying genetic causes of most cases of 46XY DSDs remains unknown. Despite the advent of genetic testing, current investigations of the causes of DSDs allow genetic-mechanism identification in about 20-35% of cases. This study aimed primarily to establish a rapid and high-throughput genetic test for undervirilized males with and without additional dysmorphic features. Routine chromosomal and endocrinological investigations were performed as part of DSD evaluation. We applied whole-exome sequencing (WES) complemented with multiplex ligation-dependent probe amplification to seek explainable genetic causes. Integrated computing programs were used to call and predict the functions of genetic variants. We recruited 20 patients and identified the genetic etiologies for 14 (70%) patients. A total of seven of the patients who presented isolated DSD phenotypes were found to have causative variants in the AR, MAP3K1, and FLNA genes. Moreover, the other seven patients presented additional phenotypes beyond undervirilized genitalia. Among them, two patients were compatible with CHARGE syndrome, one with Robinow syndrome, and another three with hypogonadotropic hypogonadism. One patient, who carried a heterozygous FLNA mutation, also harbored a heterozygous PTPN11 mutation and thus presented some phenotypes of Noonan syndrome. We identified several genetic variants (12 nonsense mutations and one microdeletion) that account for syndromic and nonsyndromic DSDs in the Taiwanese population. The identification of these causative genes extended our current understanding of sex development and related congenital disorders.

Cardiopulmonary prognosis of prophylactic endotracheal intubation in patients with upper gastrointestinal bleeding undergoing endoscopy.

BACKGROUND: It is controversial whether prophylactic endotracheal intubation (PEI) protects the airway before endoscopy in critically ill patients with upper gastrointestinal bleeding (UGIB). The study aimed to explore the predictive value of PEI for cardiopulmonary outcomes and identify high-risk patients with UGIB undergoing endoscopy. METHODS: Patients undergoing endoscopy for UGIB were retrospectively enrolled in the eICU Collaborative Research Database (eICU-CRD). The composite cardiopulmonary outcomes included aspiration, pneumonia, pulmonary edema, shock or hypotension, cardiac arrest, myocardial infarction, and arrhythmia. The incidence of cardiopulmonary outcomes within 48 h after endoscopy was compared between the PEI and non-PEI groups. Logistic regression analyses and propensity score matching analyses were performed to estimate effects of PEI on cardiopulmonary outcomes. Moreover, restricted cubic spline plots were used to assess for any threshold effects in the association between baseline variables and risk of cardiopulmonary outcomes (yes/no) in the PEI group. RESULTS: A total of 946 patients were divided into the PEI group (108/946, 11.4%) and the non-PEI group (838/946, 88.6%). After propensity score matching, the PEI group (n=50) had a higher incidence of cardiopulmonary outcomes (58.0% vs. 30.3%, P=0.001). PEI was a risk factor for cardiopulmonary outcomes after adjusting for confounders (odds ratio [OR] 3.176, 95% confidence interval [95% CI] 1.567-6.438, P=0.001). The subgroup analysis indicated the similar results. A shock index >0.77 was a predictor for cardiopulmonary outcomes in patients undergoing PEI (P=0.015). The probability of cardiopulmonary outcomes in the PEI group depended on the Charlson Comorbidity Index (OR 1.465, 95% CI 1.079-1.989, P=0.014) and shock index >0.77 (compared with shock index ≤0.77 [OR 2.981, 95% CI 1.186-7.492, P=0.020, AUC=0.764]). CONCLUSION: PEI may be associated with cardiopulmonary outcomes in elderly and critically ill patients with UGIB undergoing endoscopy. Furthermore, a shock index greater than 0.77 could be used as a predictor of a worse prognosis in patients undergoing PEI.

Multidisciplinary Approach to Brain Fog and Related Persisting Symptoms Post COVID-19.

A third of patients who developed COVID-19 experience a persisting, diverse array of symptoms including respiratory, neurological, and psychiatric complaints referred to as post-acute sequelae of COVID-19 (PASC). Symptoms can last for months after the original infection and appear unrelated to the severity of the initial illness, which suggests that even patients who did not require extensive interventions at the acute stage may experience new and/or long-term symptoms. Brain fog is a colloquial term for a common complaint among patients with PASC and generally implies cognitive impairment in domains of attention and processing speed. There are multiple hypotheses for etiologies and explanations of mechanisms contributing to brain fog in PASC. In this paper, we describe some of the mechanisms associated with brain fog post COVID-19 and provide readers with treatment recommendations that encompass cognition, mood disorders, sleep disorders, and neuroinflammation.

A Pilot Study of Interactive-Video Games in People with Mild Cognitive Impairment.

Early preventive strategies for improving cognitive function are crucial for people with mild cognitive impairment (MCI). Cognitive training exercises may improve cognitive functioning. However, there was limited evidence from training programs that combined cognitive-specific and physical activities, particularly in using interactive video games as interventions. This study aimed to evaluate the feasibility and effects of the interactive-video games on cognitive function, physical function, mood status and quality of life in community-dwelling people with MCI. A quasi-experimental study was undertaken. Participants in the intervention group received 60 min group-based training program once per week for 12 weeks. A generalised estimating equation (GEE) was used to examine the main effect, interactions and changes in outcomes over time. Sixteen participants completed the trial with eight in the intervention group and eight in the comparison group. The tolerable acceptance rate, perfect attendance rate, high satisfaction with the training content, and no injuries or falls demonstrated the feasibility of this program. The scores of cognitive function increased in both groups and the interaction between time and groups were significant over 12 weeks of training (p < 0.05). As the result, we determined that interactive-video games can be a safe, feasible, enjoyable intervention and user-friendly among people with MCI in community settings.

[Ginger-separated moxibustion for chronic fatigue syndrome and its effect on intestinal flora].

OBJECTIVE: To observe the effect of ginger-separated moxibustion on fatigue state and intestinal flora in patients with chronic fatigue syndrome (CFS). METHODS: A total of 62 patients with CFS were randomly divided into an observation group (31 cases, 3 cases dropped off) and a control group (31 cases, 2 cases dropped off). The patients in the control group were treated with normal diet and moderate exercise; on the basis of the control group, the patients in the observation group were treated with ginger-separated moxibustion at Zhongwan (CV 12), Shenque (CV 8) and Guanyuan (CV 4), 30 min each time, once every other day, three times a week. Both groups were intervened for 4 weeks. Before and after treatment, the fatigue scale-14 (FS-14) was used to observe the improvement of fatigue state, and 16S rRNA detection technology was used to detect the distribution of intestinal flora. RESULTS: Compared before treatment, the FS-14 score was reduced after treatment in the observation group (P<0.01), and the reduction in the observation group was larger than that in the control group (P<0.01). The relative abundance of intestinal flora was similar between the observation group and control group at the phylum and genus level before treatment. After treatment, there was no significant change of intestinal flora in the control group. However, the enterobacteriaceae, corynebacterium, erysipelothrix, actinomycetes were increased in the observation group (P<0.05), and actinomycetes, ruminococcus, lactarius had obvious flora advantages compared with the control group (P<0.05). CONCLUSION: The ginger-separated moxibustion could significantly improve the fatigue state in CFS patients, which may be related to the regulation of intestinal flora structure and the repair of intestinal barrier.

[Effect of ginger-separated moxibustion on fatigue, sleep quality and depression in patients with chronic fatigue syndrome: a randomized controlled trial].

OBJECTIVE: To observe the effect of ginger-separated moxibustion on fatigue, sleep quality and depression in the patients with chronic fatigue syndrome. METHODS: A total of 62 patients with chronic fatigue syndrome were randomized into an observation group (31 cases, 3 cases dropped off) and a control group (31 cases, 2 cases dropped off). In the control group, the patients had normal diet and proper physical exercise. In the observation group, on the basis of the control group, the ginger-separated moxibustion was added at Zhongwan (CV 12), Shenque (CV 8) and Guanyuan (CV 4), 30 min each time, once every two days, 3 times weekly. Separately, before treatment and after 4 weeks of treatment, the MOS item short form health survey (SF-36), the Pittsburgh sleep quality index (PSQI) scale and the self-rating depression scale (SDS) were adopted to evaluate the degrees of fatigue, sleep quality and depression in the patients of the two groups. RESULTS: In the observation group, the score of each item of SF-36, the score of each item of PSQI and SDS score after treatment were all improved significantly as compared with those before treatment respectively (P<0.05, P<0.01). In the control group, the scores of overall health, vitality and mental health in SF-36 and the score of sleep time of PSQI after treatment were improved as compared with those before treatment respectively (P<0.05). After treatment, the score of each item of SF-36, the scores of sleep quality, sleep time, sleep efficiency and sleep disorders of PSQI, as well as SDS score in the observation group were all better than those in the control group respectively (P<0.01, P<0.05). The score of SF-36 was relevant to the scores of PSQI and SDS in the patients of chronic fatigue syndrome (r =0.331, P<0.05; r =-0.706, P<0.01). The improvement value of SF-36 score was closely related to the improvement value of SDS score in the observation group (r =-0.657, P<0.01). CONCLUSION: The ginger-separated moxibustion effectively relieves fatigue and depression condition and improves sleep quality in the patients with chronic fatigue syndrome. The fatigue condition is relevant with sleep quality and depression condition to a certain extent in the patients.
