To analyze the clinical efficacy of acupuncture for spastic hemiplegia after stroke, this study was accomplished by considering Randomized Controlled Trials. We searched for papers that performed acupuncture for spastic hemiplegia after stroke in the China Academic Journal of the China National Knowledge Infrastructure, from January 1, 2017 to June 30, 2020. In total, 23 reports were included in this review. There are 18 studies conducted with more than 50 subjects and less than 100 subjects. The largest number of treatment was 20 times. 28days(4weeks) was the largest number of treatment period, which accounted 10 studies. The most frequently used evaluation index was The Fugl-Meyer Assessment(FMA) and Clinical Efficacy, each used 21 times and 17 times. The most frequently used acupuncture point was LI3, which was used 13 times. The retention time was 30 minutes and 11 studies were conducted. Western medicine treatment was the most common control group in 15 studies. Most of studies showed result of the intervention group was statistically significant, compared with the control group. These results suggest that acupuncture for spastic hemiplegia after stroke was effective and it was statistically more significant than the control group. However, it is difficult to confirm a conclusion, because the quality of most of studies was low.

낙동강 하구 새섬매자기 식생지역의 수리역학적 퇴적환경을 알아보기 위하여 명지와 을숙도 조간대에서 6개의 퇴적물 코어를 채취하여 퇴적물 입도와 원소분석 (주원소, 미량원소, 희토류 원소)을 수행하였다. 명지 조간대의 퇴적환경은 낙동강 하구둑 좌측 수문의 영향 때문에 퇴적물 상부 (~ 15 cm)에서 분급도가 불량하고 왜도 및 첨도는 양의 값을 보였다. 반면에 을숙도 조간대는 주 수문뿐만 아니라 좌측 수문의 방류 영향으로 정점 별로 서로 다른 퇴적상을 보였다. 퇴적환경의 변화를 알아보기 위하여 분급도, 왜도 및 첨도 등을 이용하여 Linear Discriminate Function (LDF) 분석을 진행하였으며, 그 결과 퇴적물 상부에서 주로 에너지가 강한 퇴적환경이 나타났다. 을숙도 조간대의 ES05 (식생지역)와 ES11 (비 식생지역) 정점의 원소분포는 크게 Al, Fe 및 Ca 주요원소들의 분포와 관련하는 광물구성의 영향을 받는다. 알루미노실리케이트(Aluminosilicate)를 포함하는 쇄설성 광물들은 퇴적물의 희토류 함량을 희석시키며, 특히 ES05 정점 퇴적물의 원소조성을 결정하는 주요 요인으로 작용하였다. 반면에 ES11 정점의 원소조성은 점토광물과 철수산화물, 그리고 희토류 함량이 높은 중광물에 의해 조절되는 것으로 나타났다. 따라서 새섬매자기 조간대 퇴적물의 원소조성은 광물 분별 과정의 영향을 받으며, 이는 담수-해수 혼합 지역의 퇴적환경을 반영한다.

Objective: The objectives of this study were to evaluate the effects of daily feed intake during the laying period on embryonic myogenic differentiation 1 (MYOD1), myogenic factor 5 (MYF5), and myogenic factor 6 (MYF6) gene expression in genetically fat and lean lines of chickens. Methods: An experiment in a 2×2 factorial design was conducted with two dietary intake levels (100% and 75% of nutrition recommendation) and two broiler chicken lines (fat and lean). Two lines of hens (n = 384 for each line) at 23th week of age were randomly divided into 4 treatments with 12 replicates of 16 birds. The experiment started at 27th week of age (5% egg rate) and ended at 54th week of age. Hatched eggs from the medium laying period were collected. Real time polymerase chain reaction analysis was used to analyse the MYOD1, MYF5, and MYF6 mRNA levels of E7, E9, E11, E13, and E15 body tissues and E17, E19, and E21 chest and thigh muscle samples. Results: The results indicated that there were significant effects of line, dietary intake, and interactions between them on MYOD1, MYF5, and MYF6 gene mRNA expression levels in embryonic tissues. Low daily feed intake did not change the expression trend of MYOD1 mRNA in either line, but changed the peak values, especially in lean line. Low daily feed intake altered the trend in MYF5 mRNA expression level in both lines and apparently delayed its onset. There was no apparent effect of low daily feed intake on the trends of MYF6 mRNA expression levels in either line, but it significantly changed the values on many embryonic days. Conclusion: Maternal nutrient restriction affects myogenesis and is manifested in the expression of embryonic MYOD1, MYF5, and MYF6 genes. Long term selection for fat deposition in broiler chickens changes the pattern and intensity of myogenesis.

Purpose : We aimed to investigate the effects of nutritional foods on sarcopenia prevention and physical function among the elderly living in rural communities during the COVID-19 pandemic by providing customized nutrition. Methods : This study was conducted in the rural community of SCC. Participants (n=24, over age 65) were randomly assigned into a Protein group (n=12) and a Vitamin group (n=12). The protein group was given 23 g/d of protein (whey, soybean, BCAA) for 8 weeks and the Vitamin group 23 g/d of vitamin (B, C, D, E and mixed minerals such as calcium, magnesium, zinc) for 8 weeks. All participants had their body composition such as height, weight, skeletal muscle mass, body mass index, and body fat percentage, measured using bioelectrical impedance analysis (BIA) and physical function assessed using grip strength and the short physical performance battery (SPPB). Results : At the end of the intervention, there was a significant increase in skeletal muscle mass (p<.01) in the Protein group (p=.002, 4.92 %) compared to the baseline: it increased by 2.33 %. The Vitamin group had a significant increase in body fat percentage after the intervention (p=.001, 15.35 %) compared to the baseline: body fat percentage decreased by 4.49 %. There were no significant differences in left and right Grip strength/Weight, SPPB, 4-m gait speed, chair stand test, and sense of balance in both groups. Conclusion : The findings from this study suggest that 8 weeks of protein intake have a significant effect on skeletal muscle mass and body fat percentage. Protein intake helped promoting the health of the elderly in rural community during the COVID-19 pandemic. It will assist creating a foundation for providing customized nutrition for the elderly in rural community in the future.

Objectives : Recently, the number of patients with dry eye syndrome has been steadily increasing. However, established treatment for it does not yet exist. This study compared electronic moxibustion with acupuncture for patients with dry eye in terms of efficacy and safety. Methods : This trial was designed as an investigator-initiated, single-blinded, comparative, randomized controlled trial. Thirty patients with dry eye were randomized to the electronic moxibustion treatment group(EMG) or the acupuncture treatment group(AG) in equal proportion. The participants who assigned to the EMG were treated with electronic moxibustion to ten acupoints including both sides of BL2, GB14, TE23, and LI4 for 12 minutes. The participants who were assigned to the AG were treated with acupuncture to the same acupoints for 15 minutes. Over 4 weeks, each intervention was carried out twelve times in total. The primary outcome was the ocular surface disease index(OSDI). The secondary outcomes were the subjective symptoms visual analog scale(VAS), quality of life(QoL), Schirmer I test(SIT), and general assessment. Adverse events and vital signs were also investigated for safety assessment. Results : In intragroup comparisons, both the EMG and the AG significantly improved the OSDI scores, the subjective symptoms VAS scores, the QoL scores, and the SIT results after 4 weeks of the trial. However, there were no statistical differences in intergroup comparisons between the two groups after 4 weeks. The safety of electronic moxibustion and acupuncture was confirmed by no occurrence of serious adverse events. Conclusions : Both electronic moxibustion and acupuncture were effective for dry eye syndrome, and they were safe. Electronic moxibustion and acupuncture can be used for dry eye syndrome as equivalent treatments.

본 연구는 농촌지역 치매노인의 삶의 질에 영향을 미치는 요인을 파악하기 위하여 PRECEDE 모형을 적용하여 관련요인들 간의 관계를 분석하여 모형을 구축하고, 모형의 적합도를 검증하고자 하였다. PRECEDE 모형의 단계에 따른 사정요인을 문헌을 참고하여 선정하고, 치매 선별검사를 통하여 치매 진단받은 대상자들을 일대일 면접조사하였다. 연구 결과 치매노인 삶의 질은 건강변인인 우울과 주관적 기억 감퇴 및 의존성에 의해 가장 많은 영향을 받는 것으로 파악되었다. 또한 건강변인에 직접 영향을 미치는 요인은 강화요인인 사회적 지지와 행동요인인 치매예방행위와 건강실천행동으로 파악되었다. 이는 강화요인과 행동요인은 삶의 질에 직접적인 영향을 미치지는 않았지만, 건강에 직접적 영향을 미쳐서 결과적으로 삶의 질에 영향을 주는 간접 영향변수로 확인되었다. 그리고 소인요인인 치매지식, 치매태도, 자기효능감은 행동에 영향을 미치는 요인으로 파악되었다. 즉 PRECEDE 모형의 단계별 요인 중 소인요인, 강화요인, 행동, 건강요인이 연결망을 이루어 삶의 질에 영향을 주는 것으로 확인되었다. 그러나 가능요인은 환경요인에 영향을 미쳤지만 삶의 질에는 영향을 미치지 않았다. 이는 대상자들의 사회적 물리적 환경이 농촌이라는 지역적 소외, 낮은 교육수준과 고령이라는 한계를 반영한 결과라고 생각한다. 그러므로 농촌지역 치매노인의 삶의 질을 향상시키기 위한 간호프로그램 계획 시 PRECEDE 모형을 적용한 다면적인 사정 요인들을 대상자의 특성를 반영하여 포괄적으로 구성할 필요가 있다고 생각한다.

Background: Pseudorabies, also known as Aujeszky's disease, is caused by the pseudorabies virus (PRV) and has been recognized as a critical disease affecting the pig industry and a wide range of animals around the world, resulting in great economic losses each year. Shandong province, one of the most vital food animal-breeding regions in China, has a very dense pig population, within which pseudorabies infections were detected in recent years. The data, however, on PRV epidemiology and coinfection rates of PRV with other major swine diseases is sparse. Objectives: This study aimed to investigate the PRV epidemiology in Shandong and analyze the current control measures. Methods: In this study, a total number of 16,457 serum samples and 1,638 tissue samples, which were collected from 362 intensive pig farms (≥ 300 sows/farm) covered all cities in Shandong, were tested by performing enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR). Results: Overall, 52.7% and 91.5% of the serum samples were positive for PRV-gE and -gB, respectively, based on ELISA results. In addition, 15.7% of the tissue samples were PCR positive for PRV. The coinfection rates of PRV with porcine circovirus type 2 (PCV2), porcine reproductive and respiratory syndrome virus, and classical swine fever virus were measured; coinfection with PCV2 was 35.0%, higher than those of the other two viruses. Macroscopic and microscopic lesions were observed in various tissues during histopathological examination. Conclusions: The results demonstrate the PRV prevalence and its coinfection rates in Shandong province and indicate that pseudorabies is endemic in pig farms in this region. This study provides epidemiological data that can be useful in the prevention and control of pseudorabies in Shandong, China.

Whole-plant corn (Zea may L.) and sorghum-sudangrass hybrid [Sorghum bicolor (L.) Moench] are major summer crops that can be fed as direct-cut or silage. Proso millet is a short-season growing crop with distinct agronomic characteristics that can be productive in marginal lands. However, information is limited about the potential production, feed value, and ensilability of proso millet forage. We evaluated proso millet as a silage crop in comparison with conventional silage crops. Proso millet was sown on June 8 and harvested on September 5 at soft-dough stage. Corn and sorghum-sudangrass hybrid were planted on May 10 and harvested on September 10 at the half milk-line and soft-dough stages, respectively. The fermentation was evaluated at 1, 2, 3, 5, 10, 15, 20, 30, and 45 days after ensiling. Although forage yield of proso millet was lower than corn and sorghum-sudangrass hybrid, its relative feed value was greater than sorghum-sudangrass hybrid. Concentrations of dry matter (DM), crude protein, and water-soluble carbohydrate decreased commonly in the ensiling forage crops. The DM loss was greater in proso millet than those in corn and sorghum-sudangrass hybrid. The in vitro dry matter digestibility declined in the forage crops as fermentation progressed. In the early stages of fermentation, pH dropped rapidly, which was stabilized in the later stages. Compared to corn and sorghum-sudangrass hybrid, the concentration of ammonia-nitrogen was greater in proso millet. The count of lactic acid bacteria reached the maximum level on day 10, with the values of 6.96, 7.77, and 6.95 Log₁₀ CFU/g fresh weight for proso millet, corn, and sorghum-sudangrass hybrid, respectively. As ensiling progressed, the concentrations of lactic acid and acetic acid of the three crops increased and lactic acid proportion became higher in the order of sorghum-sudangrass hybrid, corn, and proso millet. Overall, the shorter, fast-growing proso millet comparing with corn and sorghum-sudangrass hybrid makes this forage crop an alternative option, particularly in areas where agricultural inputs are limited. However, additional research is needed to evaluate the efficacy of viable strategies such as chemical additives or microbial inoculants to minimize ammonia-nitrogen formation and DM loss during ensiling.

BACKGROUND/OBJECTIVES: This study aimed to investigate cancer-specific survival (CSS) and associated risk factors in elderly gastric cancer (EGC) patients. SUBJECTS/METHODS: EGC patients (≥ 70 yrs) who underwent curative gastrectomy between January 2013 and December 2017 at our hospital were included. Clinicopathologic characteristics and survival data were collected. Receiver operating characteristic (ROC) analysis was used to extract the best cutoff point for body mass index (BMI). A Cox proportional hazards model was used to determine the risk factors for CSS. RESULTS: In total, 290 EGC patients were included, with a median age of 74.7 yrs. The median follow-up time was 31 (1-77) mon. The postoperative 1-yr, 3-yr and 5-yr CSS rates were 93.7%, 75.9% and 65.1%, respectively. Univariate analysis revealed risk factors for CSS, including age (hazard ratio [HR] = 1.08; 95% confidence interval [CI], 1.01-1.15), intensive care unit (ICU) admission (HR = 1.73; 95% CI, 1.08-2.79), nutritional risk screening (NRS 2002) score ≥ 5 (HR = 2.33; 95% CI, 1.49-3.75), and preoperative prognostic nutrition index score < 45 (HR = 2.06; 95% CI, 1.27-3.33). The ROC curve showed that the best BMI cutoff value was 20.6 kg/m². Multivariate analysis indicated that a BMI ≤ 20.6 kg/m² (HR = 2.30; 95% CI, 1.36-3.87), ICU admission (HR = 1.97; 95% CI, 1.17-3.30) and TNM stage (stage II: HR = 5.56; 95% CI, 1.59-19.43; stage III: HR = 16.20; 95% CI, 4.99-52.59) were significantly associated with CSS. CONCLUSIONS: Low BMI (≤ 20.6 kg/m²), ICU admission and advanced pathological TNM stages (II and III) are independent risk factors for CSS in EGC patients after curative gastrectomy. Nutrition support, better perioperative management and early diagnosis would be helpful for better survival.

Objectives : The purpose of this study is to investigate various application methods of focused ultrasound and apply them to clinical use in Korean medicine. Methods : Search was performed using the search engines of electronic databases, including PubMed, ScienceDirect, Cumulative Index to Nursing and Allied Health Literature (CINAHL), ScienceON, Oriental Medicine Advanced Searching Integrated System (OASIS), China National Knowledge Infrastructure (CNKI), Wanfang Data, Japan Science Technology Information Aggregator, Electronic (J-STAGE) and Citation Information by NII (CiNii), from inception to July 2023 without language limitation. Inclusion criteria were clinical studies including randomized controlled trials (RCTs), and animal experimental studies related with focused ultrasound treatments for acupoints or meridian sinews. Results : Total 17 papers, 7 for RCT, 6 for in vivo animal studies, and other experimental studies, were finally selected. Indications used in studies were shoulder pain, back pain, chronic back pain, and degenerative knee arthritis. In experimental studies, studies on animal models of hypoxic ischemic brain damage and hyperlipidemia were also conducted. As for the acupoints, LR3, LI4, and ST36 were used in clinical studies and, in animal experimental studies, GV20, KI1, and ST36 were used. As for the dose, 4 studies below 3 W/cm² and 3 studies in the range of 0.625 to 5 W/cm² in clinical studies, and all studies did not exceed 5 W/cm². In animal experimental studies, 0.5 W/cm², 2 W/cm², 7.5 WW/cm², 15 W/cm², 10~20 W/cm² were used. In all three studies describing the penetration depth during irradiation, it was less than 1 cm. Conclusions : We suggest that focused ultrasound is an appropriate treatment tool for stimulating the acupoints to transfer heat energy. Future studies with rigorous and well-designed RCTs for various diseases will be required to ascertain the focused ultrasound stimulate acupoints or meridian sinews.
