This study analyzed randomized controlled trials (RCTs) and case studies investigating Chuna manual therapy and variations of this term, for adolescent idiopathic scoliosis. On June 15 th , 2019, 6 online databases were used to retrieve studies. A total of 527 articles were retrieved, and 14 RCTs and 20 case studies were selected for review. Typically, the frequency of Chuna therapy was 1-2 times/week. The most common period of treatment was 12 months in RCTs and 3-6 months in case studies. Cobb's angle was the most frequent evaluation index used (11 RCTs and 20 case studies). In control groups, brace treatment was used in 8 RCTs. In 6 RCTs and 20 case studies, Cobb's angle significantly decreased after Chuna therapy, and in 4 RCTs, Chuna therapy was as effective as brace treatment, with no significant difference between groups. Adverse events were not reported except for minor reactions in only 3 case studies. This review suggested that Chuna therapy for adolescent idiopathic scoliosis was more advantageous than and as effective as brace treatment in most cases, although the risk of bias in 13 RCTs was unclear.
Background The tear film breakup time (tBUT) is a clinical evaluation of evaporative dry eye disease assessed by instilling topical fluorescein into the eyes. In the present study, we introduce a new diagnostic test, blinking tolerance time (BTT), for self-evaluation of tear-film stability. We compared the results with the tBUT and validated the BTT test for self-assessment of tear film instability. Methods This was a prospective controlled study involving 212 eyes of 106 participants 20–79 years of age. A total of 114 eyes of 57 dry eye patients and 98 eyes of 49 healthy subjects were included in the study. All patients and subjects were administered the following tests to diagnose dry eye disease: Ocular Surface Disease Index, BTT, tBUT, slit-lamp examination, corneal stain score, and Schirmer I test (without anesthesia). Patients and subjects were instructed not to blink for as long possible after reset blinking. The time interval between the reset blink and the next blink was measured. The mean of 3 tBUT values in both the right and left eyes was defined as tBUTBE. Correlations between the BTT and tBUTBE were also evaluated. To evaluate the diagnostic efficacy of the BTT and tBUT tests, receiver operating characteristic (ROC) curves were generated to obtain a cutoff score, and the sensitivities of the tests against the specificity at all possible thresholds were plotted. Results Spearman’s correlation analysis revealed a significant weakly positive correlation between BTT and tBUTBE (r = 0.447; p = 0.000). The intraclass correlation coefficient (ICC) of the tBUT was 0.679 (95% confidence interval [CI]: 0.575–0.765) and the ICC of the BTT was 0.904 (95% CI: 0.867–0.932). The area under the ROC curve did not significantly differ between the tBUTBE (0.678) and BTT (0.628, p = 0.641). When the cutoff value of the BTT test was set to 8.1 s, the sensitivity was 63.3% and the specificity was 56.1%. Conclusion The BTT test is a simple, inexpensive, and effective method for self-diagnosing dry eye that can also be used in the clinical setting.
Alzheimer’s disease (AD) is a neurodegenerative disease and is characterized by the deposition of the [Formula: see text]-Amyloid peptide ([Formula: see text]A), which causes the inflammation of neurons. Bee venom (BV) elicits a strong anti-inflammatory response, and therefore we conducted an in vitro experiment to study the efficacy of BV in an AD cellular model. To mimic AD, the U87MG cell line was incubated for 168 hours with 2.5 [Formula: see text]M [Formula: see text]A. Changes were confirmed by microscopy, and peptides were measured under stain-free conditions using homo-tomography. Sulforhodamine B analysis was performed to analyze the cell viability. Real-Time quantitative polymerase chain reaction (qPCR) analysis was conducted to analyze mRNA expression levels of pro-inflammatory cytokines (NF-[Formula: see text]B, COX-2, TNF-[Formula: see text], IL-1), and Western blot was performed to measure the Caspase-3 protein levels. BV showed no cytotoxicity at concentrations below 10 [Formula: see text]g/mL. The NF-[Formula: see text]B mRNA levels were not significantly different between the BV group and the control group. The amount of [Formula: see text]A accumulation in the BV group decreased significantly. The mRNA expression levels of COX-2, TNF-[Formula: see text], and IL-1 were significantly reduced using 10 [Formula: see text]g/mL of BV compared to those in the control group. Additionally, Caspase-3 levels were also reduced compared to those of the control group when BV was used at a concentration of 10 [Formula: see text]g/mL. BV could inhibit apoptosis and inflammatory responses in an AD cellular model. In addition, it prevented cell accumulation of [Formula: see text]A, an important pathogenic mechanism in AD.
