Objectives: The purpose of this study is to analyze the effectiveness of Guibi-tang that are used for postpartum depression. Methods: We searched on five databases [Korean studies Information Service (KISS), Oriental medicine advanced searching integrated system (OASIS), The Cochrane Library, PubMed, and China national knowledge infrastructure (CNKI)] with keywords for Postpartum depression (English, Korean, and Chinese) and evaluated the risk of bias. Meta-analysis was performed on the selected studies. Results: 8 potentially relevant articles were retrieved for further evaluation. There was evidence that Guibi-tang compared with Western medicine was significantly higher rate in total effect rate (RR 1.20, 95% CI 1.04, 1.39, p=0.01). Also, the combined therapeutic effects of Guibi-tang and Psychological intervention compared with Psychological intervention were statistically significant in total effect rate (RR 1.14, 95% CI 1.05, 1.24, p=0.002). And they showed improvement on scores of HAMD (Hamilton depression scale, HAMD) and SF-36 (36-Item short form health survey, SF-36). Conclusion: Guibi-tang appears to be more effective compared to Western medicine in the treatment of postpartum depression. The combination Guibi-tang and Psychological intervention was more effective than psychological intervention alone treated for postpartum depression. However, since unclear risk of bias, the result of this study should be considered carefully. Further clinical trials should be carried out in order to academical clinical progress regarding treatment of Postpartum Depression.

Objectives: To examine the efficacy and safety of cupping therapy for insomnia disorder and provide clinical evidence that could contribute to further research. Methods: We searched randomized controlled trials (RCTs) that verified effects of cupping therapy for insomnia disorder from 11 domestic and foreign databases. Included studies were evaluated using Risk of Bias (RoB). Results: Nineteen RCTs were selected. Wet cupping was more frequently used than dry cupping. Moving cupping was mostly used among dry cupping methods. Dry cupping was mainly performed in Bladder Meridian on the back. Wet cupping was mainly performed on BL18, LR14, and BL15. The most common treatment period was 4 weeks. The average number of treatments per week was about 2.4 times for all types of cupping, about 3.2 times for dry cupping and about 1.9 times for wet cupping. All selected studies showed a significant sleep improvement compared to the control group. As a result of the meta-analysis, in terms of effective rate, SAS score, and SDS score, the wet cupping in combination with acupuncture was significantly more effective than acupuncture alone, although the quality of selected RCTs was low. Conclusions: Cupping therapy is effective for insomnia disorder. Based on results of this study, it is reasonable to use wet cupping two times per week on BL18, LR14, and BL15 or use moving cupping three times per week in Bladder Meridian on the back for 4 weeks to treat insomnia disorder.

Objectives : Alcohol-induced liver disease advances as to reactive oxygen species (ROS) and cellular lipid peroxidation increase. We examined the hepatoprotective effects of Zingiber officinale Roscoe rhizome extract (ZR), Pueraria lobata Ohwi flower extracts (PF), and a newly developed herbal juice (HJ), which was a combination of ZR and PF extracts, against ethanol-induced hepatotoxicity. Methods: The study utilized the human hepatoma cell line HepG2 cells to validate the hepatoprotective effect of HJ (50~200 ㎍/mL) against ethanol (EtOH, 700 mM)-induced liver damage. Results: HJ effectively reduced the protein expression of sterol regulatory element-binding transcription factor 1, adiponectin, and AMP-activated protein kinase in EtOH-induced HepG2 cells. The levels of ROS, total cholesterol, and triglycerides, which are the result of various synthesis and lipogenesis processes induced by EtOH in the liver, were reduced by HJ. Furthermore, the activities of alcohol dehydrogenase and aldehyde dehydrogenase, enzymes linked to alcohol degradation, were more effectively downregulated by HJ treatment compared to treatment with ZR and PF alone, all without causing cytotoxic effects. Conclusions: HJ protects the liver by inhibiting EtOH-induced lipogenesis, lowering ROS generation, and improving alcohol degradation, which is more effective than ZR and PF alone. Further, in vivo experiments can offer additional evidence regarding the effectiveness, safety, and underlying mechanism of action of HJ.
Purpose - The increasing share of Korean private label products (PLPs) in the domestic market helped generate lucrative revenue. In recent years, major South Korean retailers have begun to cast their sights on overseas markets and actively export their PLPs. In China, the proportion of private label fresh food (PLFF) is gradually expanding amid the development of the new retailing model. A profound understanding of the relationship between private label fresh produce and purchase intention may be the answer to helping Chinese retailer private labels expand supply chains in Korea. This study, taking Chinese retailers as an example, examines the impacts of selection factors of private label fresh food and perceived value on purchase intention. Apart from that, the relationship between the selection factors and purchase intention will be analyzed with perceived value as a mediator. Design/methodology - This work aims to empirically analyze the purchase intention of private label fresh food using statistical analysis. In this study, a hypothetical causal model consisting of 6 latent variables and 24 measured variables is developed based on the literature review. To validate the research hypotheses and the research model, SPSS23.0/AMOS23.0 is used to analyze factors such as validity and reliability, as well as structural equation modeling. Findings - The hypothetical model established in this study is of general applicability. In respect to PLFF, perceived value, while significantly influencing purchase intention in combination with four selection factors (perceived quality, perceived price, brand trust, and store image), mediates partially between the first three factors and purchase intention, which rules out the impact and mediating effect of store image on purchase intention. Originality/value - These research results, as helpful insights into the present circumstances of Chinese PLFF in the domestic market, provide useful information and guidance for Korean retailers and service providers to innovate production and service, as well as develop marketing and promotion strategies, so that they can shift private label goods with advantages from domestic demand to export, thus increasing overseas profitability. Further, this work will also contribute to relevant research.
The price-to-earnings ratio (PER) is an important indicator to measure the stock price and profitability of a firm; it is also the most used valuation indicator among investors. When using the PER to compare the investment values of different stocks, these stocks must come from the same sector. This study mainly focuses on the China's listed manufacturing firms. By learning from previous research results and analyzing the current situation, we studied the correlation between the manufacturing sector's PER and its influencing factors from both macro and micro perspectives, the combination of which eventually sheds light on such correlation. Analyzing GDP growth rate data, Manufacturing Purchasing Managers' Index, and other macroeconomic variables from 2008 to 2018, we conclude that these variables jointly have a certain impact on the average PER of the manufacturing sector. We then form panel data based on relevant (2014-2018) data gathered from 317 of China's A-listed manufacturing firms to study the impact of micro-variables on PER. By using Stata and other software to analyze the panel data, we reach the conclusion that the Debt to Asset Ratio, Return on Equity, EPS growth rate, Operating Profit Ratio, Dividend Payout Ratio, and firm size have a significant impact on PER. The Current Ratio, Treasury Stock ratio and Ownership Concentration have no distinct effect on PER. Based on our empirical findings, we design a theoretical model that affects the PER.

The aim of this review is to consolidate findings from clinical investigations spanning the past decade regarding the impact of acupuncture on Parkinson's disease (PD). The objective is to assess the efficacy of acupuncture as a therapeutic approach to PD, with the intention of informing future clinical practices and advancing the foundation for subsequent research endeavors in this area. A comprehensive literature search was conducted to identify clinical trials exploring the effects of acupuncture on PD between January 2014 and August 2023. Databases search included PubMed, EMBASE, CNKI, OASIS, KISS, KMBASE, RISS, and ScienceON. Quantitative evidence from randomized controlled trials (RCTs) was systematically reviewed, and the methodological quality of the included studies was assessed using Cochrane's risk of bias tool. Meta-analysis was performed using Review Manager (RevMan) 5.4.1 software. The systematic review encompassed a total of 38 RCTs involving 2,786 participants. Meta-analysis of 12 studies revealed that individuals treated with a combination of acupuncture and Western medicine exhibited notable improvements compared to those receiving Western medicine alone or sham acupuncture alongside Western medicine. However, the overall quality of the RCTs was deemed low, and no serious adverse events were reported. Across clinical investigations conducted in the past decade, acupuncture appears to hold promise as a complementary treatment for PD patients when administered alongside Western medicine. Nevertheless, this study identifies certain limitations that warrant consideration in future research endeavors. Enhanced emphasis on conducting high-quality RCTs is imperative to comprehensively evaluate the efficacy of acupuncture in managing PD.
Background: Growing evidence suggests that beta-hydroxy-beta-methylbutyrate (HMB), arginine (Arg), and glutamine (Gln) positively affect wound recovery. This study investigated the effects of long-term administration of HMB/Arg/Gln on pressure ulcer (PU) healing in sedentary older adults admitted to geriatric and rehabilitation care facilities. Methods: This was a pilot retrospective case (standard of care and HMB/Arg/Gln)-control (standard of care alone) clinical study. Outcome measures were relative healing rates and Pressure Ulcer Scale for Healing (PUSH) scores (calculated after 4, 8, 12, 16, and 20 weeks) and time to healing. Results: The study subpopulation was comprised of 14 participants (four males, 28.6%) with the median age of 85.5 years (interquartile range [IQR], 82.0-90.2 years). The control subpopulation was comprised of 31 participants (18 males, 58.1%) with the median age of 84.0 years (IQR, 78.0-90.0 years). At the beginning of follow-up, there were no statistically significant demographic (sex and age) and clinical (main diagnosis, baseline area, and PU perimeter) differences between the groups. During the study period, there were no significant differences in the relative healing rates and PUSH scores between the subpopulations. The median time to complete healing in the study and control populations was 170.0 days (95% confidence interval [CI], 85.7-254.3) and 218.0 days (95% CI, 149.2- 286.7) (log-rank, chi-square=3.99; p<0.046), respectively. Conclusion: More than 20 weeks of HMB/Arg/Gln supplementation had a positive effect on difficult PU healing in older adults with multiple comorbidities.
Objective: The current body of evidence lacks clarity regarding the comparative efficacy and safety of radiofrequency ablation (RFA) and microwave ablation (MWA) as minimally invasive treatments for benign thyroid nodules. The primary objective of this study is to clarify these concerns. Materials and Methods: A comprehensive search was conducted using the Cochrane Library, Scopus, Europe PMC, and Medline databases until October 10th, 2023, using a combination of relevant keywords. This study incorporated literature that compared RFA and MWA for benign thyroid nodules. The primary outcome was the volume reduction ratio (VRR) from baseline to follow-up. Secondary outcomes were symptom score, cosmetic score, ablation time, major complications rate, hemorrhage, hoarseness, skin burn, cough, and sympathetic nerve injury. We used Risk of Bias in Non-randomized Studies - of Interventions (ROBINS-I) tool to assess the risk of bias in the included studies. We employed random effects models to analyze the standardized mean difference (SMD) and odds ratio for the presentation of outcomes. Results: Nine studies with 2707 nodules were included. The results of our meta-analysis indicated similar efficacy between RFA and MWA in terms of VRR during the 1 (SMD 0.06; 95% confidence interval [CI]: -0.13 to 0.26; P = 0.52) and 3 (SMD 0.11; 95% CI: -0.03 to 0.25; P = 0.12) months of follow-up. VRR was significantly higher in RFA than in MWA at the 6 (SMD 0.25; 95% CI: 0.06-0.43; P = 0.008) and 12 month of follow-up (SMD 0.38; 95% CI: 0.17 to 0.59; P < 0.001). There were no significant differences between RFA and MWA in symptom scores, cosmetic scores, or the incidence of complications, including hemorrhage, hoarseness, skin burn, cough, and sympathetic nerve injury. Conclusion: RFA showed a higher VRR than MWA at 6 and 12-month follow-ups, with a comparable safety profile.
Interstitial lung diseases (ILDs) are a diverse collection of lung disorders sharing similar features, such as inflammation and fibrosis. The diagnosis and management of ILD require a multidisciplinary approach using clinical, radiological, and pathological evaluation. Progressive pulmonary fibrosis (PPF) is a distinct form of progressive and fibrotic disease, occurring in ILD cases other than in idiopathic pulmonary fibrosis (IPF). It is defined based on clinical symptoms, lung function, and chest imaging, regardless of the underlying condition. The progression to PPF must be monitored through a combination of pulmonary function tests (forced vital capacity [FVC] and diffusing capacity of the lung for carbon monoxide), an assessment of symptoms, and computed tomography scans, with regular follow-up. Although the precise mechanisms of PPF remain unclear, there is evidence of shared pathogenetic mechanisms with IPF, contributing to similar disease behavior and worse prognosis compared to non-PPF ILD. Pharmacological treatment of PPF includes immunomodulatory agents to reduce inflammation and the use of antifibrotics to target progressive fibrosis. Nintedanib, a known antifibrotic agent, was found to be effective in slowing IPF progression and reducing the annual rate of decline in FVC among patients with PPF compared to placebos. Nonpharmacological treatment, including pulmonary rehabilitation, supplemental oxygen therapy, and vaccination, also play important roles in the management of PPF, leading to comprehensive care for patients with ILD. Although there is currently no cure for PPF, there are treatments that can help slow the progression of the disease and improve quality of life.
Background/Aims: Despite short-acting β2-agonist (SABA) overuse being associated with poor asthma outcomes, data on SABA use in South Korea is scarce. Herein, we describe prescription patterns of SABA and other asthma medications in patients from the South Korean cohort of the SABA use IN Asthma (SABINA) III study. Methods: This study included patients with asthma aged ≥ 12 years, who had ≥ 3 consultations with the same healthcare provider, and medical records containing data for ≥ 12 months prior to the study visit. Patients were classified by investigator-defined asthma severity (per 2017 Global Initiative for Asthma recommendations) and practice type (primary or specialist care). Data on disease characteristics, asthma treatments, and clinical outcomes in the 12 months before the study visit were collected using electronic case report forms. Results: Data from 476 patients (mean age, 55.4 years; female, 63.0%) were analyzed. Most patients were treated by specialists (83.7%) and had moderate-to-severe asthma (91.0%). Overall, 7.6% of patients were prescribed ≥ 3 SABA canisters (defined as over-prescription). In patients prescribed SABA in addition to maintenance therapy, 47.4% were over-prescribed SABA. Most patients (95.4%) were prescribed a fixed-dose combination of an inhaled corticosteroid and a long-acting β2-agonist as maintenance therapy. Although asthma was well-controlled/partly-controlled in 91.6% of patients, 29.6% experienced ≥ 1 severe asthma exacerbation. Conclusions: SABA over-prescription was reported in nearly 50% of patients prescribed SABA in addition to maintenance therapy, underscoring the need to align clinical practices with the latest evidence-based recommendations and educate physicians and patients on appropriate SABA use.
