RESUMEN
OBJECTIVE: This study investigated the efficacy of acupuncture in preventing chemotherapy-induced peripheral neuropathy (CIPN) in patients with colorectal cancer (CRC). METHODS: This single center, randomized, controlled, single-blind clinical trial randomly assigned patients with stage 3 CRC attending outpatient clinics in China Medical University Hospital to either verum or sham acupuncture treatment concurrently with chemotherapy. Primary outcomes were nerve conduction velocity (NCV) and touch thresholds of limb terminals. Secondary outcomes were total and subdomain scores on the Functional Assessment of Cancer Therapy-General (FACT-G), and scores on the FACT/GOG-Ntx subscale and the Brief Pain Inventory-Short Form (BPI-SF), at baseline, weeks 12, 36, and follow-up (week 48). RESULTS: Thirty-two patients met the inclusion criteria and received verum acupuncture (N = 16) or sham acupuncture (N = 16). Under the -intent-to-treat principle, 26 participants were analyzed. Significant changes from baseline for questionnaire scores and sensory NCV were observed in both study groups. Sham acupuncture was associated with significant reductions from baseline in motor NCV and sensory touch thresholds; no such changes were observed with verum acupuncture. No serious adverse events were reported. CONCLUSION: Prophylactic acupuncture may exert neuroprotective effects on mechanical or tactile touch thresholds during chemotherapy regimens in patients with CRC, with evidence of this protectiveness persisting at 6 months' follow-up. The lack of change in motor NCV values with verum acupuncture indicates neuroprotective effects. Sensory NCV values and patient-reported outcomes did not differ significantly between the study groups.

BACKGROUND: Patients with rheumatoid arthritis (RA) have a higher risk of coronary heart disease (CHD). Acupuncture, a commonly used treatment for patients with RA, has not been reported to prevent CHD in patients with RA. We aimed to assess the risk of developing CHD in acupuncture users and non-users of patients with RA. METHODS: We identified 29,741 patients with newly diagnosed RA from January 1997 to December 2010 from the Registry of Catastrophic Illness Patients Database from the Taiwanese National Health Insurance Research Database. Among them, 10,199 patients received acupuncture (acupuncture users), and 19,542 patients did not receive acupuncture (no-acupuncture users). After performing 1:1 propensity score matching by sex, age, baseline comorbidity, conventional treatment, initial diagnostic year, and index year, there were 9932 patients in both the acupuncture and no-acupuncture cohorts. The main outcome was the diagnosis of CHD in patients with RA in the acupuncture and no-acupuncture cohorts. RESULTS: Acupuncture users had a lower incidence of CHD than non-users (adjusted HR = 0.60, 95% CI = 0.55-0.65). The estimated cumulative incidence of CHD was significantly lower in the acupuncture cohort (log-rank test, p < .001). Subgroup analysis showed that patients receiving manual acupuncture of traditional Chinese medicine style, electroacupuncture, or combination of both all had a lower incidence of CHD than patients never receiving acupuncture treatment. The beneficial effect of acupuncture on preventing CHD was independent of age, sex, diabetes mellitus, hypertension, hyperlipidemia, and statins use. CONCLUSIONS: This is the first large-scale study to reveal that acupuncture might have beneficial effect on reducing the risk of CHD in patients with RA. This study may provide useful information for clinical utilization and future studies.

Purpose: Disability is the comorbidity of dementia for which there is no available preventive measure. The aim of this study was to investigate the association between acupuncture treatment and the risk of disability development in dementia patients. Patients and Methods: A cohort study was performed using a nationwide health database in Taiwan. The included dementia patients were divided into acupuncture and non-acupuncture cohorts based on whether they received acupuncture treatment during the follow-up period. The variables in the two cohorts were controlled by 1:1 propensity-score matching. The difference in disability development in dementia patients between the acupuncture and non-acupuncture cohorts was also analyzed. Subgroup analyses were performed using socioeconomic variables, comorbidities and anti-dementia agents (donepezil, rivastigmine, galantamine and memantine) used for dementia treatment. Results: A total of 9,760 dementia patients met our inclusion criteria, and patients were divided into an equal number (n=2,422) of acupuncture and non-acupuncture groups, respectively, after 1:1 propensity-score matching. The dementia patients had a lower risk of disability development after acupuncture treatment than those who did not receive acupuncture treatment (adjusted hazard ratio 0.65, 95% confidence interval 0.60-0.70, p < 0.001). The results were independent of basic variables or comorbidities in the two cohorts. Patients who did not use anti-dementia agents had a lower risk of developing disability after receiving acupuncture intervention than those who used anti-dementia agents. Conclusion: Our results revealed the relationship between acupuncture intervention and decreased risk of developing disability in dementia patients. The results are useful for dementia treatment, trial design and further planning of care programs.
RESUMEN
OBJECTIVE: To demonstrate that acupuncture is beneficial for decreasing the risk of ischaemic stroke in patients with rheumatoid arthritis (RA). DESIGN: A propensity score-matched cohort study. SETTING: A nationwide population-based study. PARTICIPANTS: Patients with RA diagnosed between 1 January 1997 and 31 December 2010, through the National Health Insurance Research Database in Taiwan. INTERVENTIONS: Patients who were administered acupuncture therapy from the initial date of RA diagnosis to 31 December 2010 were included in the acupuncture cohort. Patients who did not receive acupuncture treatment during the same time interval constituted the no-acupuncture cohort. PRIMARY OUTCOME MEASURES: A Cox regression model was used to adjust for age, sex, comorbidities, and types of drugs used. We compared the subhazard ratios (SHRs) of ischaemic stroke between these two cohorts through competing-risks regression models. RESULTS: After 1:1 propensity score matching, a total of 23 226 patients with newly diagnosed RA were equally subgrouped into acupuncture cohort or no-acupuncture cohort according to their use of acupuncture. The basic characteristics of these patients were similar. A lower cumulative incidence of ischaemic stroke was found in the acupuncture cohort (log-rank test, p<0.001; immortal time (period from initial diagnosis of RA to index date) 1065 days; mean number of acupuncture visits 9.83. In the end, 341 patients in the acupuncture cohort (5.95 per 1000 person-years) and 605 patients in the no-acupuncture cohort (12.4 per 1000 person-years) experienced ischaemic stroke (adjusted SHR 0.57, 95% CI 0.50 to 0.65). The advantage of lowering ischaemic stroke incidence through acupuncture therapy in RA patients was independent of sex, age, types of drugs used, and comorbidities. CONCLUSIONS: This study showed the beneficial effect of acupuncture in reducing the incidence of ischaemic stroke in patients with RA.

OBJECTIVE: To evaluate the modulation of RhoA/Rho kinase (ROCK), a small Rho GTPase, on migration, invasion and proliferation of fibroblast like synoviocytes (FLS) from rheumatoid arthritis (RA) patients. METHODS: RA FLS were collected from active RA patients. And 10% fetal bovine serum (FBS) and interleukin-1ß (IL-1ß) were used as stimuli in migration and proliferation experiments respectively. RhoA activity was measured by pull down assay while ROCK activity by Western blot. FLS migration and invasion in vitro were measured by the Transwell chamber method. And thiazolyl blue tetrazolium bromide (MTT) test was used to detect cell proliferation. RESULTS: There were increased activities of RhoA and ROCK in ex vivo FLS from RA versus OA patients and healthy control. The migrated cell number of FBS-induced, C3-treated and Y27632-treated groups was 85 ± 14, 51 ± 15 and 42 ± 11 respectively. The Matrigel invading cell number of 3 groups was 64 ± 13, 39 ± 12 and 26 ± 9 respectively. Statistical differences existed in cell number between FBS-induced, C3-treated or Y27632-treated group (P < 0.05) in above migration and invasion experiments. Inhibition of RhoA and ROCK activity also suppressed the cytoskeletal reorganization and proliferation of RA FLS. CONCLUSION: Increased RhoA/ROCK activity may contribute to abnormal migration, invasion and proliferation of RA FLS. Thus inhibition of ROCK activity may be a new therapeutic target for RA.

Background: The pressure ulcer is a complication developed from dementia. The aim of this study is to study the association between the development of pressure ulcers and the use of acupuncture therapy in patients with dementia. Methods: We performed a retrospective 1:1 propensity score-matched cohort study to investigate the association between acupuncture therapy and the risk of pressure ulcers in patients with dementia. Results: A total of 8,994 patients were identified, 237 patients in the acupuncture cohort and 362 patients in the no-acupuncture cohort developed pressure ulcers. A reduced cumulative incidence of pressure ulcers was observed in the acupuncture cohort (P<0.001). The association between acupuncture and reducing the incidence of pressure ulcers was not affected by sex, age, residence, income, or comorbidities. The variables of etiologies to cause dementia did not change the final result. In the subgroups analyses, the patients without medication for dementia control had a significantly lower rate of pressure ulcers development when they had accepted acupuncture therapy (log-rank test, P<0.001). Conclusion: Our results revealed the association between acupuncture therapy and a reduced incidence of pressure ulcer development in patients with dementia. This finding offers important ideas for further research.
RESUMEN
Objective: The aim of this study is to investigate the association between acupuncture therapy and the risk of fracture in patient with osteoarthritis (OA). Design: The authors performed a 1:1 propensity score-matched cohort study to analyze patient with OA between January 1, 1997 and December 31, 2010 through the Taiwanese National Health Insurance Research Database. Patients who received acupuncture therapy from the initial date of diagnosis of OA to December 31, 2010 were included in the acupuncture cohort. Patients who did not receive acupuncture during the same follow-up period were defined as the no-acupuncture cohort. A Cox regression model was used to adjust for sex, age, comorbidities, prescription, and surgical experiences. Hazard ratios (HRs) were compared between the two cohorts. Results: A total of 3416 patients were identified after 1:1 propensity score matching. The patients had similar basic characteristics. In the final analysis, 292 patients in the acupuncture cohort (30.06 per 1000 person-years) and 431 patients in the no-acupuncture cohort (56.08 per 1000 person-years) developed fractures (adjusted HRs 0.57, 95% confidence interval 0.49-0.67). A reduced cumulative incidence of fracture was found in the acupuncture cohort (log-rank test, p < 0.001). The association between acupuncture and reducing the fracture incidence was independent of sex, comorbidities, drugs use, and surgical experiences. Conclusion: Their results revealed the association between acupuncture therapies and a reduced incidence of fracture development in patients with OA. This finding provides noteworthy ideas for further research.

BACKGROUND: Major depressive disorder is a significant public health concern, which often leads to loss of productivity, functional decline, and various complications. The aim of this study was to investigate the effectiveness of acupuncture in the risk reduction of coronary heart disease (CHD) in patients with depression. METHODS: We enrolled patients diagnosed with depression between January 1, 1997, and December 31, 2010, through the Taiwanese National Health Insurance Research Database (NHIRD). Propensity score was used to match equal numbers (n=14,647) of acupuncture cohort and no-acupuncture cohort based on characteristics including sex, age, baseline comorbidity and medication. Patients were followed up until December 31, 2013, or withdrawn from the NHIRD. The Cox regression model was used to compare the hazard ratios (HRs) of CHD in the two cohorts. RESULTS: The basic characteristics of the two groups were similar. A lower cumulative incidence of CHD was noted in the acupuncture cohort (Log rank test, p < 0.001). Over time, 1626 patients in the acupuncture cohort (21.05 per 1000 person-years) and 2412 patients in the no-acupuncture cohort (39.84 per 1000 person-years) developed CHD (adjusted HR=0.50, 95% CI 0.47-0.53). The decreased CHD incidence was independent of age, sex, comorbidities, and medications used. The cumulative incidence of CHD was significantly lower in the acupuncture cohort than in the no-acupuncture cohort (Log rank test, p<0.001). CONCLUSION: The results provided a real-world evidence that acupuncture may have beneficial effect on CHD risk reduction in patients with depression.
RESUMEN
BACKGROUND: Depression is one of the most disabling disorders, which causes long-term complications such as neurodegenerative disorder and cerebrovascular disease. Some patients with depression seek acupuncture treatment. We aimed to investigate the association between acupuncture treatment and the risk of dementia in patients with depression from the perspective of real-world evidence. METHODS: Patients over 18 years old and newly diagnosed with depression between 1997 and 2010 were selected from the Taiwanese National Health Insurance Research Database and followed up until the end of 2013. Propensity score was used to match equal numbers of patients 1:1 (N = 16,609 per group) into acupuncture and non-acupuncture cohorts based on characteristics including sex, age, baseline comorbidity and drug use. The outcome measurement was the comparison of dementia incidence in the two cohorts. RESULTS: Compared with the non-acupuncture cohort, patients who received acupuncture treatment had a decreased risk of dementia (adjusted hazard ratio (aHR) = 0.54; 95% confidence interval (CI) = 0.50-0.58, P < 0.001) after adjustment for age, sex, comorbidities and drug use. Compared with depression patients who did not receive acupuncture, the aHR of vascular dementia and Alzheimer's disease incidences for patients who had acupuncture therapy was 0.59 (95% CI 0.48-0.71) and 0.51 (95% CI 0.39-0.67), respectively. The cumulative incidence of dementia was significantly lower in the acupuncture cohort than in the non-acupuncture cohort (Log rank test, p < 0.001). CONCLUSION: The present study from real-world data revealed that acupuncture reduced the risk of dementia in depression patients, which supports healthcare decisions in clinical practice.
RESUMEN
Background: Rheumatoid arthritis is an autoimmune disease that may lead to severe complications. The fruit of Psoralea corylifolia L. (PCL) is widely used in traditional Chinese medicine as a well-known herbal treatment for orthopedic diseases. However, there is a lack of studies of its effects on rheumatoid arthritis. The purpose of the study was to investigate the effects and mechanisms of concentrated herbal granules of PCL on rheumatoid arthritis to provide some insights for future development of new drug for the treatment of rheumatoid arthritis. Methods: We used collagen-induced arthritis (CIA) DBA/1J mice as an experimental model to mimic human rheumatoid arthritis. The mice were immunized with collagen on days 0 and 21 and then orally administered 200 mg/kg/day PCL on days 22-49. Starch was used as a control. The mice were sacrificed on day 50. Clinical phenotypes, joint histopathology, and immunological profiles were measured. Results: Compared to the CIA or CIA + Starch group, the CIA + PCL group had significantly ameliorated clinical severity and decreased paw swelling. Histopathological analysis of the hind paws showed that PCL mitigated the erosion of cartilage and the proliferation of synovial tissues. There were significant differences in the levels of TNF-α, IL-6 and IL-17A, as measured by ELISA, and the percentages of CD4 + IL-17A+, CD4 + TNF-α+, CD4 + IFN-γ+ T cells. Furthermore, we also found that in mice treated with CIA + PCL, the percentage and number of bone marrow-derived suppressor cells (MDSCs; Gr1+ CD11b+) increased significantly. Conclusions: We provided evidence for the potential antiarthritic effects of PCL through the inhibition of inflammation and increase of MDSCs. These findings indicate that PCL may be a promising therapeutic herb for the treatment of rheumatoid arthritis.
RESUMEN
BACKGROUND: The aim of this study was to investigate the effectiveness of acupuncture in decreasing the risk of stroke in patients with fibromyalgia. METHODS: We enrolled patients who was newly diagnosed as having fibromyalgia between 1 January, 2000 and 31 December, 2010 from the Taiwanese National Health Insurance Research Database. The claim data for both the acupuncture cohort and non-acupuncture cohort were assessed from the index date to 31 December, 2013. A Cox regression model adjusted for age, sex, comorbidities, and drugs use was used to compare the hazard ratios of the two cohorts. The cumulative incidence of stroke was estimated by using the Kaplan-Meier method. RESULTS: After performing a propensity score matching with a 1:1 ratio, there were 65,487 patients in the acupuncture and non-acupuncture cohorts with similar distributions in the baseline characteristics. The cumulative incidence of stroke was significantly lower in the acupuncture cohort (log-rank test, p < 0.001). In the follow-up period, 4,216 patients in the acupuncture cohort (11.01 per 1000 person-years) and 6,849 patients in the non-acupuncture cohort (19.82 per 1000 person-years) suffered from stroke (adjusted HR 0.53, 95% CI 0.51-0.55). Acupuncture favorably affected the incidence of stroke regardless of the patient's age, sex, comorbidities, and conventional drug use. CONCLUSIONS: Our study found that acupuncture might have a beneficial effect on reducing the risk of stroke in patients with fibromyalgia in Taiwan. Additional clinical and basic science studies are warranted.

In recent years, acupuncture has gained in popularity worldwide. However, recent epidemiological studies are lacking. We conducted this study to investigate the trends in acupuncture utilization among adults in Taiwan from 2002 to 2011. We analyzed data from the Longitudinal Health Insurance Database 2000 (LHID 2000), which contains all original claims data for 1 million beneficiaries randomly sampled from the registry of all beneficiaries enrolled in the National Health Insurance (NHI) program in 2000. The one-year prevalence of acupuncture use among adults increased from 7.98% in 2002 to 10.9% in 2011. Acupuncture use significantly increased yearly (incidence rate ratio = 1.04, 95% CI = 1.03-1.05, p<0.001). Patients who were female, were middle-aged, resided in highly urbanized areas and suffered from injury or disorders of the musculoskeletal system were prone to more frequent acupuncture use. Our study revealed that the utilization of acupuncture became increasingly popular in Taiwan from 2002 to 2011. Our findings may provide useful information for clinical practice and research as well as for health policy decision making.

BACKGROUND: The aim of this study was to understand whether acupuncture can decrease the risk of coronary heart disease (CHD) in patients with fibromyalgia. METHODS: Using data from the Taiwanese National Health Insurance Research Database, we performed a propensity score-matched cohort study to analyze patients with fibromyalgia diagnosed between 1 January 2000 and 31 December 2010. Patients who received acupuncture treatment, beginning with their initial date of fibromyalgia diagnosis and extending to 31 December 2010, were regarded as the acupuncture cohort. The no-acupuncture cohort comprised patients who never received acupuncture through 31 December 2010. A Cox regression model was used to adjust for age, sex, comorbidities, and drugs used. The HRs of the acupuncture and no-acupuncture cohorts were compared. RESULTS: After performing a 1:1 propensity score match, 58,899 patients in both cohorts were identified. Baseline characteristics were similar in both cohorts. The cumulative incidence of CHD was significantly lower in the acupuncture cohort (log-rank test, p < 0.001). In the follow-up period, 4389 patients in the acupuncture cohort (17.44 per 1000 person-years) and 8133 patients in the no-acupuncture cohort (38.36 per 1000 person-years) developed CHD (adjusted HR 0.43, 95% CI 0.41-0.45). The beneficial effect of acupuncture on the incidence of CHD was independent of age, sex, comorbidities, and statins used. CONCLUSIONS: Our study confirmed that acupuncture reduced the risk of CHD in patients with fibromyalgia in Taiwan. Further clinical and mechanistic studies are warranted.

ETHNOPHARMACOLOGICAL RELEVANCE: Large-scale study of traditional Chinese medicine (TCM) usage among patients with rheumatoid arthritis (RA) is lacking. The aim of this study is to evaluate the TCM usage among RA patients in Taiwan. MATERIALS AND METHODS: We examined the "registry for catastrophic illness patient dataset" of the National Health Insurance Research Database (NHIRD; n=23 million people) in Taiwan. Patients (n=25,263) newly diagnosed as RA in 2001-2009 were included and then followed-up until the end of 2011. Based on the medical utilization, they were further categorized into TCM users (n= 6891; 27.3%) and non-TCM users (n=18,372; 72.7%). The demographic data and core prescription patterns of the TCM users were analyzed. RESULTS: Compared to non-TCM user, TCM users were younger (mean age: 49.6 versus 54.0 years), had a higher female/male ratio (82.7%/17.3% versus 74.1%/25.9%), resided in more urbanized area. Herbal remedies were the most commonly used therapeutic approach (76.4%), followed by combining acupuncture (21.1%). The frequency of outpatient visits in TCM users was higher across all disease categories except circulatory system. The most commonly prescribed formula and herb was Shang-Jong-Shiah-Tong-Yong-Tong-Feng-Wan and Rhizoma Corydalis, respectively. The analysis of core pattern revealed that Dang-Gui-Nian-Tong-Tang, Shu-Jing-Huo-Xie-Tang, Gui-Zhi-Shao-Yao-Zhi-Mu-Tang, Myrrha and Olibanum, were among the most frequently used combinations. RA patients who had anxiety and depression, allergic rhinitis, osteoporosis, menstrual disorder, and menopausal syndrome were prone to have more TCM visits compared to non-TCM users. CONCLUSIONS: Our population-based study revealed the high prevalence and specific usage patterns of TCM in the RA patients in Taiwan. The information could be used for further pharmacological investigation and clinical trials.
