Validation of the 2011 and 2016 American college of rheumatology diagnostic criteria for fibromyalgia in a Chinese population.

PURPOSE: To provide a foundation for clinical diagnosis, epidemiological investigation and intervention trials, we examined the reliability and validity of the American College of Rheumatology (ACR) 2011 and 2016 survey diagnostic criteria among Chinese patients based on the fibromyalgia severity (FS) scale. METHODS: In this study, 200 fibromyalgia patients diagnosed according to the 1990 criteria (1990c) were matched with rheumatoid arthritis (RA) patients based on age and gender. The FS scale score and its subscales were examined to determine their correlations with the revised fibromyalgia impact questionnaire (FIQR). Receiver operator characteristic (ROC) analysis was performed, and test-retest reliability, internal consistency, and construct validity were examined. RESULTS: The area under the curve (AUC) for the ACR 2011c and 2016c was 0.870 and 0.845, respectively, and the sensitivity and specificity were 78.0% and 96.0% for the 2011c and 70.5% and 98.5% for the 2016c, respectively. The FS scale and its subscales were confirmed to exhibit good internal consistency, and they were significantly correlated with the FIQR, thereby indicating adequate construct validity. Using a lower cutoff value 11 points for the FS scale score based on the generalized pain requirement might be a more effective approach in the Chinese population; this approach yielded an AUC of 0.923 and a sensitivity of 87.0% and specificity of 97.5%. CONCLUSION: The 2011c and 2016c are reliable instruments for diagnosing fibromyalgia patients in China. The FS scale could be a valid tool to assist in fibromyalgia diagnosis, and a cutoff value 11 points is more suitable in Chinese patients. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT03381131.

The Chinese version of the ACR 2011c and 2016c are valid tools for fibromyalgia diagnosis; and a cutoff value 11 points for FS might be more suitable to assist in fibromyalgia diagnosis in Chinese population. The Chinese 2011c and 2016c for fibromyalgia diagnosis can be found as an appendix to this article.

A Chinese version of the revised Fibromyalgia Impact Questionnaire: A validation study.

OBJECTIVE: The revised Fibromyalgia Impact Questionnaire (FIQR) was developed to measure the quality of life of patients with fibromyalgia in randomized controlled trials and routine care. The purpose of this study was to translate and adapt the FIQR from English to Chinese, and to examine the validity and reliability of the Chinese version of the FIQR (CFIQR). METHODS: Following the translation of the FIQR, fibromyalgia patients from 6 centers were recruited and completed the CFIQR, the validated Chinese version of the Medical Outcome Study Short Form 36 Health Survey (SF-36) and the Beck Depression Inventory (BDI). In this study, Cronbach's alpha coefficient, test-retest reliability and item total correlation were used for evaluating external and internal reliability; and criterion and structural validity were evaluated. RESULTS: A total of 200 fibromyalgia patients completed the study. The internal consistency was excellent (Cronbach's alpha .90, .88, .88 and .93 for function, overall impact, symptoms scales and total score, respectively; item-total correlations from .25 to .83.) Test-retest reliability levels of the CFIQR total and subscale scores were strong correlation (intraclass correlation coefficient >0.75). Furthermore, there were significant correlations between the 3 subscale and the total score of the CFIQR and the SF-36, as well as the CFIQR and the BDI, by criterion validity (P < .01). Confirmatory factor analysis gave an acceptable value for structural validity according to the 3-factor structures of function, overall impact and symptoms. CONCLUSIONS: The CFIQR is a valid and reliable instrument for both clinical practice and research purposes with Chinese speakers globally. [ClinicalTrials.gov: NCT03381131].

The effect of text message reminders on medication adherence among patients with coronary heart disease: A systematic review and meta-analysis.

BACKGROUND: To determine the effectiveness of text message reminders (TMR) on medication adherence (MA) and to investigate the effects of TMR on clinical outcomes. METHODS: The PubMed, Cochrane library, EMbase, and China Biology Medicine databases were searched for randomized-controlled trials with TMR as the intervention for patients with coronary heart disease. Two reviewers independently extracted data and assessed the risk of bias. Meta-analysis was conducted using Stata 15.0 software. RESULTS: In total, 1678 patients in 6 trials were included. Compared with the control group, the MA was 2.85 times greater among the intervention group (RR [relative risk] 2.85; 95% confidence interval [CI] 1.07-7.58). TMR reduced systolic blood pressure (BP) (weighted mean difference) = -6.51; 95% CI -9.79 to -3.23), cholesterol (standard mean difference = -0.26; 95% CI -0.4 to -0.12) and increased the number of patients with BP <140/90 mm Hg (RR 1.39; 95% CI 1.26-1.54). CONCLUSION: TMR significantly promoted MA and reduced systolic BP, cholesterol level, and body mass index, but had no effect on mortality, diastolic BP, or lipoproteins. However, substantial heterogeneity existed in our analyses.

Ba-Duan-Jin alleviates pain and fibromyalgia-related symptoms in patients with fibromyalgia: results of a randomised controlled trial.

OBJECTIVES: Fibromyalgia is a chronic debilitating pain syndrome. There has been growing interest in the development of non-pharmacological therapies. Ba-Duan-Jin is an ancient Chinese exercise for health promotion, yet easy to learn. The purpose of this study is to evaluate the effectiveness of Ba-Duan-Jin in managing fibromyalgia symptoms experienced by Chinese patients. METHODS: In this randomised, usual therapy-controlled study, patients with fibromyalgia practiced Ba-Duan-Jin for one hour, twice a week for 12 weeks. The primary outcome measure was change in the Visual Analogue Scale for pain (pain VAS). Secondary outcomes included the Fibromyalgia Impact Questionnaire (FIQ), the Multidimensional Assessment of Fatigue (MAF), the Pittsburgh Sleep Quality Index (PSQI), the Beck Depression Inventory (BDI), the Perceived Stress Scale (PSS), and the Tender Point Count (TPC). These measures were assessed at baseline and after 4, 8, and 12 weeks. The Patient Global Impression of Change (PGIC) was collected at week 12. The Mann-Whitney U-test was performed using the intention-to-treat population. RESULTS: A total of 62 fibromyalgia patients were randomised to the Ba-Duan-Jin or the control groups. For the Ba-Duan-Jin group, significant improvement in pain VAS, FIQ, MAF, PSQI, and TPC were documented at weeks 4 (p≤0.046) and continued at week 8 (p≤0.003). At week 12, all of the outcome measures including BDI and PSS exhibited significant improvement (p≤0.004), and PGIC ratings were significantly better (p<0.001). No significant changes in the control group were observed. CONCLUSIONS: This study suggests that Ba-Duan-Jin exercise has the potential to be a valuable non-pharmacological intervention among Chinese fibromyalgia patients.

Synthesis, crystal structure and fluorescence spectrum of a cadmium(II) sulfaquinoxaline complex.

catena-Poly[[[4-amino-N-(quinoxalin-2-yl)benzenesulfonamidato]aquacadmium(II)]-µ-4-amino-N-(quinoxalin-2-yl)benzenesulfonamidato], [Cd(C14H11N4O2S)2(H2O)], has been synthesized hydrothermally and characterized by single-crystal X-ray diffraction, elemental analysis, fluorescence, IR and thermal analysis. Single-crystal X-ray analysis reveals that the complex is a one-dimensional zigzag chain structure, and the Cd(II) cation has a distorted octahedral coordination geometry formed by five N atoms from three different sulfaquinoxaline ligands and one O atom from a water molecule. The fluorescence spectrum reveals that the complex emits strong blue fluorescence and thermal analysis shows that the complex has high thermal stability.

Electrochemical properties of a cobalt(II) complex with sulfadiazine and 1,3-bis(pyridin-4-yl)propane.

catena-Poly[[bis{4-[(pyrimidin-2-ylazanidyl)sulfonyl]aniline}cobalt(II)]-bis[µ-1,3-bis(pyridin-4-yl)propane]], [Co(C10H8N4O4S2)2(C13H14N2)]n or [Co(L)2(bpp)]n, crystallizes as a one-dimensional polymeric structure which is further stabilized by intermolecular hydrogen bonding. The refined Flack parameter, -0.001 (10), indicates that the model represents the correct absolute structure. Investigation of the thermal stability shows that the complex is stable up to 543 K. The structure is of interest with respect to its electrochemical properties in the reduction reaction of H2O2 to H2O.

[Study on leuprorelin acetate in treatment of uterine adenomyosis with infertility].

OBJECTIVE: To study clinical efficacy of leuprorelin acetate in treatment of uterine adenomyosis with infertility. METHODS: From January 1,2011 to March 31,2012, 166 cycles in 166 infertile patients combined with uterine adenomyosis undergoing in vitro fertilization embryo transplant (IVF-ET) with long protocol ovum induction by leuprorelin acetate in centre of medical reproduction, ningbo women and children's hospital were studied retrospectively. In the mean time, 200 cycles in 200 infertile patients with tubal factors were enrolled as control group.The volume of uterus and outcome of IVF-ET were compared and studied between two groups. RESULTS: (1) Volume of uterus:in adenomyosis group, after 2-6 cycles of injecting leuprorelin acetate (3.75 mg/28 days), the mean uterine volume was shrinked from (180 ± 73) cm(3) to (86 ± 67) cm(3) (P < 0.05). (2) Outcome of IVF-ET:the rate of embryo implantation was 39.1% in adenomyosis group and 35.8% in control group. The rate of clinical pregnancy was 54.2% in adenomyosis group and 53.7% in control group. The rate of abortion was 4.7% in adenomyosis group and 4.2% in control group. They all did not show statistical differences (P > 0.05). (3) In adenomyosis group, the rate of fertilization, two pronuclear (2PN) and superior embryo were 67.2%(319/475), 60.8% (289/475) and 52.9% (162/306) in patients with failed pregnancy and 74.2% (423/570), 67.7% (386/570) and 62.1% (256/412) in patients with successful pregnancy after IVF-ET, which reached significant difference (P < 0.05). CONCLUSION: Leuprorelin acetate could improve volume of uterine adenomyosis and outcome of pregnancy in patients undergoing IVF-ET.
