  • Background: The aim of this systematic review was to investigate whether stem cells could be effectively applied in targeted therapy of breast cancer. Material and Method: A systematic literature search was performed for original articles published from January 2007 until May 2012. Results: Nine studies met the inclusion criteria for phase I or II clinical trials, of which three used stem cells as vehicles, two trials used autologous hematopoetic stem cells and in four trials cancer stem cells were targeted. Mesenchymal stem cells (MSCs) were applied as cellular vehicles to transfer therapeutic agents. Cell therapy with MSC can successfully target resistant cancers. Cancer stem cells were selectively targeted via a proteasome-dependent suicide gene leading to tumor regression. $Wnt/{\beta}$-catenin signaling pathway has been also evidenced to be an attractive CSC-target. Conclusions: This systematic review focused on two different concepts of stem cells and breast cancer marking a turning point in the trials that applied stem cells as cellular vehicles for targeted delivery therapy as well as CSC-targeted therapies. Applying stem cells as targeted therapy could be an effective therapeutic approach for treatment of breast cancer in the clinic and in therapeutic marketing; however this needs to be confirmed with further clinical investigations.

  • Purpose: To summarize and review the methodological quality of the evidence from trials examining the effectiveness of physical exercise in patients undergoing allogeneic hematopoietic stem cell transplantation (Allo-HSCT). Methods: Six randomized clinical trials (RCTs) were identified, reviewed for substantive results, and assessed for methodological quality. Results: Six trials met all methodological criteria on the modified Jadad score above 3 out of 5 points. Failure to blind the outcome assessor, and failure to describe the method of blinding of outcome assessor appropriately were the most prevalent methodological shortcomings. Various exercise modalities have been applied, differing in content, frequency, intensity, and duration. Positive results have been observed in part for a diverse set of outcomes, including physical and psychological performance. Conclusion: The trials reviewed in this study were of moderate methodological quality. They suggest that exercise in patients undergoing Allo-HSCT may be safe and feasible, and in part patients benefit from increased physical performance both during and after transplantation. Future RCTs should use larger samples, appropriate comparison groups, and a standard of outcome measures, and examine what kind of exercise intervention (aerobic vs. resistance vs. combined) is the most effective for Allo-HSCT patients. It would be necessary to define contraindication for exercise to guarantee its safety.

  • Background: We performed this meta-analysis to assess the effectiveness and safety of axillary dissection in old women. Methods: The Cochrane Library, PubMed, EMBASE and Chinese Biomedical Literature Database were searched and all randomized controlled trials of axillary dissection in old women (at least 60 years old) were considered. Meta-analyses were completed using RevMan5.1. Results: Three eligible randomized controlled trials (RCTs) including 5,337 patients were considered. There was weak evidence in favour of axillary dissection (AD) in old women. The meta-analysis showed that the overall survival (OS) after 1, 3, 5 and 7 years and the disease free survival (DFS) after 1, 3 and 5 year were not statistically significantly different between AD and no AD groups. However, there was a difference in the 7 year DFS. Conclusions: Axillary dissection did not provide survival benefit to the old women with breast cancer analysed. Therefore, axillary dissection is not well-indicated in old women with breast cancer.

  • A study of three feeding trials was conducted to investigate the dietary protein requirements of Pacific white shrimp (Litopenaeus vannamei) at three different growth stages. Six experimental diets were formulated to include increasing protein levels of 25, 30, 35, 40, 45, and 50% (designated as P25, P30, P35, P40, P45, and P50, respectively) for three feeding trials. The three feeding trials were conducted in different-sized shrimp at 0.65 g (trial 1), 4.80 g (trial 2), and 10.5 g (trial 3). Triplicate groups of shrimp were fed one of the experimental diets for 36, 42, and 48 days in trials 1, 2, and 3, respectively. In trial 1, the growth performance was not affected by the dietary protein levels. However, protein efficiency ratio was significantly higher in P30 diet compared to P40, P45, and P50 diets. In trial 2, growth rate was significantly higher in P35 diet than in P25 diet. In trial 3, the lowest growth performance was obtained in P25 diet which significantly differed from that of other experimental diets. Broken line analysis of growth data indicates that the optimal dietary level of crude protein is 34.5, 35.6, and 32.2% for small-, medium-, and large-sized (juvenile, sub-adult, and adult stages) Pacific white shrimp, respectively.

  • Crossover trials of new drugs in the treatment of angina pectoris, which frequently use treadmill exercise test for the assessment of its efficacy, produce censored survival times. In this paper we consider analysis approaches for censored survival times from crossover trials. Previously, a stratified Cox model for paired observation and nonparametric methods have been presented as possible analysis methods. On the other hand, the differences of two survival times would produce interval-censored survival times and we propose a Cox model for interval-censored data as n alternative analysis method. Example data is analyzed in order to compare these different methods.

  • Effects of the Seokchangpo-Wonji-Tang on recovery from disorder of stomach, liver and mental-faculty in alcoholism were studied using male Sprague-Dawley rats. The rats were assigned into 4 groups; normal, control and Seokchangpo-Wonji-Tang(SWT) group. Control group administered ethanol(25 v/v %) at a dose 3g/kg, while SWT group administered 50mg/kg of SWT 30min before treating same dose of ethanol as control group for 10 days, orally. The gastric ulceration and also GOT and GPT activities in rats were checked, and all groups were subjected to trials of straight channel on the 1st day and to those of multiple T-maze during the following 3 days. The gastric ulceration, GOT and GPT activities were increased in control group, but decreased in SWT group significantly. The time required in normal group for the straight channel of the 2nd and 3rd trials was significantly shorter than that of the 1 st, while the control group showed no significance. In the time required for the multiple T-maze trials, the control group showed no significance. But in the straight or T-maze trials, the SWT group showed significant decrease in the time required against the control group.

  • A shaking motion could be used to improve fish escapement from a cod-end net by creating a sieving effect over the swept volume or by disturbing the optomotor response of the fish. In this study, a perpendicular shaking motion was generated in a towed cod-end net by a circular canvas attached to the end of the codend, which formed a biased cap-like shape. This concept was tested by using a model in a flow tank and by towing a prototype cod-end during sea trials. For the model tests, the amplitude of the shaking motion was $0.6{\pm}0.1$ times the rear diameter of the cod-end, and the period of the shaking motion was $2.6{\pm}0.1$ s at a flow velocity of 0.6 or 0.8 m/s. In the sea trials, the amplitude was $0.5{\pm}0.2$ times the rear diameter of the cod-end, and the period of the shaking motion was $7{\pm}4$ s at towing speeds of 1.2 or 1.7 m/s. Thus, the shaking amplitude during the sea trials was equal to or less than that observed in the tank tests, and the shaking period was twice as long. The shaking motion described by the amplitude and period could be an effective means to stimulate fish escapement from cod-end during fishing operations considering the response of the fish.

  • Objectives: This study aimed to review randomized controlled trials on the effectiveness of korean medicine for chronic urinary tract infections. Methods: We analyzed the randomized controlled trials that intervented korean medicine treatment on chronic urinary tract infections retrieved using seven databases. Literature search was conducted on August 10, 2020. Results: Of the 188 studies searched, 8 studies were finally selected. In all studies, the treatment group was treated with korean medicine and the control group was treated with western medicine. Although the evaluation index was different for each study, all the indexes in the treatment group were significantly improved compared to the control group. Conclusions: Korean medicine treatment for chronic urinary tract infections had a significant effect compared to the western medicine treatment. Further high quality randomized controlled trials should be carried out to verify the strong evidence and safety of herbal medicine treatment.

  • Objectives : The objective of this study is to report the efficacy of acupuncture and moxibustion for the treatment of fetal breech presentation. Methods : We searched papers in PubMed, using the keywords "breech and moxibustion" and "breech and acupuncture". Search range includes randomized clinical trials(RCTs), controlled clinical trials(CCTs), case reports, and case series. Each original article must have an abstract in English. Finally, 7 RCTs from 102 were included in this review. Results : As a result of analyzing the 7 RCTs, five trials hold that moxibustion or acupuncture at BL67 has been shown to produce a positive effect for the correction of breech presentation and the other two trials indicated no beneficial effect. However, one of the latter could not come to a conclusion owing to the unsatisfactory compliance record of the participants. Conclusions : Acupuncture and moxibustion may be effective to correct fetal breech presentation. In this regard, the related clinical researches are worth to be conducted.

  • A total of 1,235 studies were retrieved on June 23, 2019, from 3 databases. Selected 59 studies were evaluated by year of publication, study type, subject condition/disease, acupoint, standards for reporting interventions in clinical trials of moxibustion (STRICTOM), Cochrane risk of bias (RoB), and risk of bias assessment tool for non-randomized study (RoBANS). Most studies were conducted in 2011, after which the number of studies decreased. The most common study type was 25 case reports (CR), 16 uncontrolled clinical trials (UCT), 11 randomized controlled trials (RCT), and 7 controlled clinical trials (CCT). Moxibustion treatment was mainly used for musculoskeletal and circulatory diseases/conditions. A total of 83 acupoints were used, A-shi points being the most used. As for STRICTOM, an average of 7.4 items were satisfactory for UCT and CR without a control group, and an average of 9.4 items were satisfactory for RCT and CCT. RCT was assessed using the RoB, and many items were rated as uncertain. In this study, the need for RCT of moxibustion treatment in Korea was identified. The detailed description of study methods and results will provide evidence for the efficacy of moxibustion treatment in preventive and therapeutic aspects of Korean traditional medicine.
