Objectives This systematic review aimed to provide evidence for the effectiveness and safety of Chuna manual therapy (CMT) for carpal tunnel syndrome (CTS). Methods We searched 12 electronic databases (PubMed, Ovid-MEDLINE, EMBASE, The Cochrane Library, CNKI, CiNii, ScienceON, KMbase, KISS, OASIS, KMTANK, and RISS) up to the end of October 2021. We only included randomized controlled trials (RCTs) investigating CMT for the treatment of CTS. The methodological quality of the included RCTs was evaluated using the Cochrane Risk of Bias Tool 1.0. Results Six RCTs were eligible for inclusion in our study. A meta-analysis of four studies demonstrated positive results for the use of CMT when used in conjunction with Korean medicine treatment compared to those for Western conservative treatment for CTS. Conjunction treatment significantly improved the total efficacy rate compared to conservative treatment alone (P=0.0007, n=4). Conclusions There is reliable evidence for the use of CMT in treating CTS based on a published meta-analysis. To measure only the effect of Chuna, an experimental group should be designed with Chuna alone to evaluate its effectiveness. However, it should be noted that the studies included in this systematic review were heterogeneous and of low quality, thus warranting further investigation using well-designed RCTs.

Objectives The purpose of this study was to analyze the trend of recent randomized controlled trials (RCTs) that used herbal medicine for the treatment of tic disorders in China and to evaluate the efficacy and safety of the treatment. Methods RCTs published from January 2017 to December 2021 were searched for using the China National Knowledge Infrastructure (CNKI). These were then analyzed using herbal medicine treatment methods and their results. Results A total of 35 randomized controlled trials were selected and analyzed. In most studies, evaluation indicators such as the Yale tic symptom scale and total effective rate were significantly improved in the herbal medicine treatment group compared to the control group. The most commonly used herb for tic disorder was Uncaria Rhynchophylla (釣鉤藤), followed by Glycyrrhizae Radix (甘草), Gastrodiae Rhizoma (天麻), Paeoniae Radix Alba (白芍藥), Batryticatus (白殭蠶), Poria (茯笭), and Bupleuri Radix (柴胡). In all studies that reported adverse events, herbal medicine was identified as a relatively safe treatment with fewer adverse reactions or no significant difference compared with the control group. Conclusions Based on the results of RCTs, herbal medicine has been shown to be safe and effective for the treatment of intellectual disability. However, additional well-designed large-scale clinical trials are needed to confirm these findings.

Background: Bronchiectasis patients with neutrophilic airway inflammation develop symptoms of chronic cough, sputum production, and recurrent exacerbations. Roflumilast has anti-inflammatory actions via decreased neutrophilic airway inflammation. The effectiveness of roflumilast to reduce bronchiectasis exacerbation has never been evaluated. Methods: We conducted a double-blinded, randomized, placebo-controlled trial. Our primary objective was to assess the effect of roflumilast compared with that of a placebo in reducing exacerbation rates in bronchiectasis patients. The secondary objectives were the changes in forced expiratory volume in 1 second (FEV₁) and St. George's Respiratory Questionnaire (SGRQ). Bronchiectasis patients older than 18 years who had had two exacerbations during the previous 12 months were randomly assigned to receive either 500 ㎍ of either roflumilast or a placebo once daily for 6 months in a 1:1 ratio. Results: Forty bronchiectasis patients who had experienced exacerbations were screened. Thirty patients completed the study after 6 months of treatment: roflumilast group (n=15) and placebo group (n=15). The rates of exacerbations were 0.57 and 0.59 per patient in the roflumilast and placebo groups, respectively. Prebronchodilator FEV₁ increased by 0.07 L from baseline in the roflumilast group and decreased by 0.015 L in the placebo group, but the difference was not significant. No significant differences were observed in the change of SGRQ scores between the roflumilast and placebo groups. Roflumilast had significant side effects, including loss of appetite and headache. Conclusion: Roflumilast did not significantly affect the rate of exacerbations or quality of life. However, FEV₁ tended to improve more in the roflumilast group than in the placebo group.

Background: The use of low-dose inhaled corticosteroid-formoterol as reliever monotherapy has recently been recommended in the asthma treatment guidelines. However, the efficacy of this treatment strategy has not yet been determined during the stepping-down period in moderate asthma. This study aimed to evaluate the feasibility of reducing treatment to as-needed budesonide-formoterol (BFM) in moderate asthma with complete remission. Methods: We randomly assigned 31 patients (8 males and 23 females with a mean age of 57.2 years) with complete remission of asthma by inhaled BFM (160/4.5 ㎍) twice daily to receive BFM (160/4.5 ㎍) as needed (16 patients), or budesonide (BUD) (200 ㎍) twice daily (15 patients). The study was an open-label study done for 48 weeks, with the primary outcome as the cumulative percentages of patients with treatment failure (asthma exacerbation or loss of asthma control or lack of satisfaction after using medications) in the two groups. Results: Six patients (42%) using as-needed BFM had treatment failure, as compared with three patients (21.4%) using BUD maintenance (hazards ratio for as-needed BFM, 1.77; 95% confidential interval, 0.44-7.12; p=0.41). The changes in forced expiratory volume in 1 second were -211.3 mL with as-needed BFM versus -97.8 mL with BUD maintenance (difference, 113.5 mL; p=0.75) and the change in fractional exhaled nitric oxide was significantly higher in both groups, at 8.68 parts per billion (ppb) in the as-needed BFM group and 2.5 ppb. in the BUD maintenance group (difference, 6.18 ppb; p=0.049). Conclusion: Compared with BUD maintenance, there were no significant differences in treatment failure rate in patients who received as-needed BFM during the stepping down period in moderate asthma. However, they showed reduced lung function and relapsed airway inflammation. The results are limited by imprecision, and further large RCTs are needed.

The high success rate of dental treatment is dependent on the cooperation of pediatric patients during procedures. Dental treatment often causes pain, particularly in children. The factors in providing treatment to pediatric patients include the characteristics and location of the tooth, profoundness of the anesthesia including the type of local anesthetic, and cooperation of the patient. Previous studies have examined several techniques to successfully achieve profound pulpal anesthesia in maxillary permanent teeth. The dentist should select the injection technique to be used based on patient needs. In children, either buccal with palatal injections or buccal with intra-septal injections may be used to anesthetize the permanent maxillary first molar. Buccal with palatal injections are commonly used prior to routine maxillary dental procedures. Currently, there are only a few studies on the employment of buccal with intra-septal injections to anesthetize permanent maxillary first molars in pediatric patients. This review will focus on efficacy of buccal with palatal versus buccal with intra-septal pulpal anesthesia of the permanent maxillary first molars in pediatric patients and aim to determine which technique should be used during routine dental procedures.

Objectives The purpose of this study is to present evidence by analyzing the research trends in acupuncture treatment in the last 10 years for thromboangiitis obliterans. Methods Randomized controlled trials about acupuncture on thromboangiitis obliterans were searched China National Knowledge Infrastructure (CNKI), PubMed, EMBASE, Cochrane Library, Oriental Medicine Advanced Searching Integrated System (OASIS), ScienceON, Koreanstudies Information Service System (KISS) and Research Information Sharing Service (RISS) from January 1, 2011 to November 13, 2021. Only randomized controlled trials were selected and we assessed the risk of bias (RoB) according to the revised Cochrane RoB2 criteria. Results A total of 5 randomized controlled trials (RCTs) were selected in this review and all were conducted in China. A total of 326 participants were in 5 RCTs. SP10, ST36, GB34 was the most commonly used treatment point. There were four types of acupuncture used: manual acupuncture, embedding acupuncture, pharmacopuncture, electroacupuncture. The most commonly used indicator for evaluation was the total efficacy rate, and all five studies were significantly higher. Conclusions All selected studies showed the group treated with acupuncture treatments on thromboangiitis obliterans were statistically more effective than the control group. However, the number of studies is too small and the interpretation of the results is limited due to the inclusion of subjective evaluation. So more objective and systematic studies should be conducted continuously.

Purpose: TThe experiment was designed to compare the efficiency of ventilation between conventional BVM ventilation and a newly devised A-BVM ventilation method with Tidal volume, total ventilation rate, average Ventilation speed, and average Ventilation volume. Methods: 40 Paramedical students who agreed to participate in the study were analyzed. Values were measured using IMB PASS after 2 minutes of Brayden Pro manikin with BVM and A-BVM ventilation. The difference in general characteristics was assessed by t-test and ANOVA and the difference in ventilation methods was analyzed by IBM SPSS. Results: A significant difference was found between the two ventilation methods in terms of tidal volume (t=-11.203, p<.001), ventilation time (t=-3.834, p<.001), and optimum ventilation probability (t=10.770, p<.001). A-BVM ventilation method, rather than BVM ventilation method, showed a value close to the appropriate amount recommended by Korean Advanced Life Support (500~600mL) in tidal volume, and higher in optimum ventilation probability. Conclusion: We could identify the a better mode of ventilation. Further studies on the efficacy of existing BVM ventilation methods as compared to device augmented BVM ventilation methods should be carried out to ensure that adequate ventilation is available to patients in clinical practice.

In this study, for students who gave up their studies midway through college, we investigate the reasons for dropping out of college, analyze the factors that caused students to drop out, and suggest improvement measures to effectively increase the recruitment rate of enrolled students. This study explores measures to increase student enrollment in community colleges. For this purpose, it conducted a survey of students who dropped out of G College between 2018 and 2020 from June 28 to July 9, 2021. Its analysis is based on the results of 53 students who participated in the survey. First, our results suggest that programs to develop interpersonal relationships between students, faculty, and staff are necessary. Such programs will cultivate a culture of solidarity and collective identity among students, which in turn will reinforce positive experiences in college. Moreover, by developing systems to form relationships between faculty and students, colleges can have a feedback mechanism, such as an open-study program, through which they learn what the students want and need. Through this effort, colleges can help their students adjust to campuses and enhance student satisfaction in college. Second, it is necessary to develop various extracurricular programs not only for freshmen but existing students and to run hobby and leisure activity programs. To have continuous, standing extracurricular programs instead of one-time events, colleges should set up specific goals, delivery methods and strategies. Third, colleges should renovate old and outdated buildings and facilities on campus to enhance the quality of campus life. Moreover, more comprehensive improvement of facilities and a campus environment by having various convenient and leisure facilities that meet the needs and demands of students. Fourth, it is suggested to develop programs or systems that help students to more fully engage in campus lives and activities, which in turn increases confidence and self-efficacy among students. Through such programs, students can better adjust to their majors and, therefore, will be less likely to drop out of college.

Background: The poor intracellular concentration of enrofloxacin might lead to treatment failure of cow mastitis caused by Staphylococcus aureus small colony variants (SASCVs). Objectives: In this study, enrofloxacin composite nanogels were developed to increase the intracellular therapeutic drug concentrations and enhance the efficacy of enrofloxacin against cow mastitis caused by intracellular SASCVs. Methods: Enrofloxacin composite nanogels were formulated by an electrostatic interaction between gelatin (positive charge) and sodium alginate (SA; negative charge) with the help of CaCl₂ (ionic crosslinkers) and optimized by a single factor test using the particle diameter, zeta potential (ZP), polydispersity index (PDI), loading capacity (LC), and encapsulation efficiency (EE) as indexes. The formation mechanism, structural characteristics, bioadhesion ability, cellular uptake, and the antibacterial activity of the enrofloxacin composite nanogels against intracellular SASCVs strain were studied systematically. Results: The optimized formulation was comprised of 10 mg/mL (gelatin), 5 mg/mL (SA), and 0.25 mg/mL (CaCl₂). The size, LC, EE, PDI, and ZP of the optimized enrofloxacin composite nanogels were 323.2 ± 4.3 nm, 15.4% ± 0.2%, 69.6% ± 1.3%, 0.11 ± 0.02, and -34.4 ± 0.8 mV, respectively. Transmission electron microscopy showed that the enrofloxacin composite nanogels were spherical with a smooth surface and good particle size distributions. In addition, the enrofloxacin composite nanogels could enhance the bioadhesion capacity of enrofloxacin for the SASCVs strain by adhesive studies. The minimum inhibitory concentration, minimum bactericidal concentration, minimum biofilm inhibitory concentration, and minimum biofilm eradication concentration were 2, 4, 4, and 8 ㎍/mL, respectively. The killing rate curve had a concentration-dependent bactericidal effect as increasing drug concentrations induced swifter and more radical killing effects. Conclusions: This study provides a good tendency for developing enrofloxacin composite nanogels for treating cow mastitis caused by intracellular SASCVs and other intracellular bacterial infections.

Background: Stroke is a neurological disorder characterized by brain tissue damage following a decrease in oxygen supply to brain due to blocked blood vessels. Reportedly, 80% of all stroke cases are classified as cerebral infarction, and the incidence rate of this condition increases with age. Herein, we compared the efficacies of Korean White ginseng (WG) and Korean Red Ginseng (RG) extracts (WGex and RGex, respectively) in an ischemic stroke mouse model and confirmed the underlying mechanisms of action. Methods: Mice were orally administered WGex or RGex 1 h before middle cerebral artery occlusion (MCAO), for 2 h; the size of the infarct area was measured 24 h after MCAO induction. Then, the neurological deficit score was evaluated and the efficacies of the two extracts were compared. Finally, their mechanisms of action were confirmed with tissue staining and protein quantification. Results: In the MCAO-induced ischemic stroke mouse model, WGex and RGex showed neuroprotective effects in the cortical region, with RGex demonstrating superior efficacy than WGex. Ginsenoside Rg1, a representative indicator substance, was not involved in mediating the effects of WGex and RGex. Conclusion: WGex and RGex could alleviate the brain injury caused by ischemia/reperfusion, with RGex showing a more potent effect. At 1,000 mg/kg body weight, only RGex reduced cerebral infarction and edema, and both anti-inflammatory and anti-apoptotic pathways were involved in mediating these effects.
