  • Background: Breast cancer is one of the most common cancers among women worldwide and the HER2 receptor plays an important role in its development and progression. This systematic review aimed to summarize the role of HER2 in brain metastasis in patients with breast cancer. Materials and Methods: We conducted a literature search by advanced search in title field using the Scopus, Pubmed, and Google scholar databases until the end of June 2014. With metastasis, metastatic, HER2, brain, and breast cancer, as terms of search we selected 31 articles, which were reviewed by two independent and blinded expert reviewers. The studies were first selected according to their titles and abstracts. Quality of the studies were then assessed using the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) protocol for observational studies and CONSORT(Consolidation of Standards for Reporting Trials) protocol for clinical trials. For statistical analyses, we used STATA, version 11.0 software. Forest and funnel diagrams were drawn and for heterogeneity, index was also considered. Also we used meta regression analysis. Results: Finally, we reviewed 10 studies. The prevalence of brain metastasis in HER2-positive breast cancer patients was 24.9%. There was publication bias in the reviewed studies. Meta regression analysis showed that follow up time had no significant effect (p=0.396) on the prevalence of brain metastasis. Conclusions: The results showed a high prevalence of brain metastasis in HER2 positive breast cancer patients.

  • Objectives : To evaluate and summarize the efficacy and safety of acupuncture treatment (AT) in chronic fatigue syndrome (CFS). Methods : Fifteen databases (Pubmed, Cochrane, EMBASE, AMED, CINAHL, CNKI, Wanfang, and eight Korean databases) were searched up to September 2016. Only trials in which acupuncture was the sole treatment were included. Fatigue was used as the primary outcome measure, while the quality of life, pain, mood disorders, and adverse events were used as secondary outcome measures. We adopted three classifications: AT vs Sham AT, AT vs Wait-list, AT vs Western medication. The Cochrane risk of bias tool was used to assess the methodological quality. Results : A total of 11 randomized controlled trials involving 869 participants were identified. In comparison with Sham AT, AT significantly alleviated fatigue and pain, but no conclusions about the quality of life and mood disorders could be drawn. In the Wait-list group and Western medication groups, patients with CFS might feel less fatigued following acupuncture treatment, but the evidence was insufficient due to lack of study. Nine of 11 RCTs (81.8%) reported adverse events and there were two cases of mild subcutaneous hemorrhage, but no serious adverse cases. Conclusion : This review found evidence that patients with CFS may generally benefit from alleviation of symptoms by acupuncture treatment, and there is no evidence of worsening symptoms or causing of serious adverse events. A positive effect on fatigue and pain was observed, but no conclusion for improving quality of life and mood disorders.

  • Objectives: Postoperative pain is one of postoperative complications in patients with solid tumor. This systematic review and meta-analysis were aimed to evaluate the efficacy of acupuncture for postoperative pain in solid tumor. Methods: We searched for randomized controlled trials (RCTs) using acupuncture for postoperative pain in adult patients with solid tumor up to September 2016. Acupuncture was defined as manual acupuncture, electroacupuncture and pharmacopuncture. The following databases were searched: PubMed, EMBASE, Cochrane Library, CNKI, CiNii, KoreaMed, Kmbase, KISS, NDSL, KISTI. The results of the studies were meta-analyzed and the risk of bias was assessed. Results: Five studies were included in this review. When acupuncture was compared with usual care, Prince-Henry pain scale score was significantly lower in acupuncture group (MD=-0.44, 95% CI: -0.62 to -0.26, P<0.001, $I^2=87%$) and 10 points pain score (including Numeric Rating Scale and Visual Analog Scale) was lower in acupuncture group but not significantly (MD=-1.00, 95% CI: -2.00 to -0.00, p=0.05). When acupuncture was compared with sham acupuncture, 10 points pain score was significantly lower in acupuncture group (MD=-0.39, 95% CI: -0.65 to -0.14, p=0.002, $I^2=0%$). Any serious adverse events were not reported. Conclusion: This review shows that acupuncture may be considered for postoperative pain in patients with solid tumor without serious adverse events. However, only a few studies were included in this study, further investigation is needed in this area.

  • Objectives: The purpose of this study is to investigate the weight loss effects of auricular acupuncture in obese patients. Methods: Six databases (Research Information Sharing Service [RISS], Korean studies Information Service System [KISS], Oriental Medicine Advanced Searching Integrated System [OASIS], PubMed, The Cochrane Library, China National Knowledge Infrastructure [CNKI]) were searched up to May 20, 2020. Eight eligible randomized controlled trials were included the present study. The quality of included studies was assessed by the Cochrane risk of bias tool and a meta-analysis was performed by Review Manager software. A meta-analysis was conducted using a random-effects model and a subgroup analysis was performed to detect the sources of heterogeneity, identify the selection of acupuncture methods and explore its contributions to the weight loss effects. Results: Among 8 trials, 5 trials used auricular acupuncture and 2 trials used auricular acupressure, 1 trial used both types of intervention. Most commonly selected acupoints were Shenmen (TF4) and stomach (CO4). Treatment duration was six to twelve weeks, and total treatment session was six to twelve. Compared to the control groups, auricular acupuncture significantly decreased body weight, body mass index (BMI), high density lipoprotein-cholesterol (HDL) and ghrelin. For the selection of acupuncture methods, both methods performed similarly in most outcome except waist circumference (WC), body fat percentage (BFP), and triglycerides (TG). Conclusions: We found that auricular acupuncture can be effective for weight loss and controlling appetite. However, the findings should be interpreted with caution due to heterogeneity. So further vigorous and well-designed studies should be conducted to strengthen the evidence of the use of auricular acupuncture for obesity.

  • Objectives: The objective of this study was to provide clinical evidence to support the use of a herbal medicine (Cheonwangbosim-Dan/Tianwangbuxin-Pellet (TWBXP)) for insomnia. Methods: Randomized controlled trials that verified effects of Herbal Medicine (Cheonwangbosim-Dan, Tianwangbuxin-Pellet) treating primary insomnia were carried out. A literature search of English, Chinese, Korean databases was also performed. The selected literature were assessed by Risk of Bias (RoB). Results: The total number of selected trials was 13 RCTs. Among the 13 RCTs, 10 were meta-analyzed. The Chinese Classification of Mental Disorders-3 (CCMD-3) was frequently used as the diagnostic criteria for interventions during the analysis of the use of herbal medicine (Cheonwangbosim-Dan/Tianwangbuxin-Pellet) for management of primary insomnia. As for outcome measurement, the effective rate was used. From the Meta-analysis of the studies, it was established that the insomnia cure effective rate in the TWBXP group was higher than that in the Western Medicine (WM) group (RR: 1.15, 95% CI: 1.07 to 1.24, p<0.0001, $I^2=33%$). Also, the effective rate in the TWBXP+ACU group was significantly different compared to the WM group (RR: 1.32, 95% CI: 1.13 to 1.54, p=0.0004, $I^2=0%$). The quality of the selected RCTs was low. Conclusions: Herbal medicine (Cheonwangbosim-Dan/Tianwangbuxin-Pellet) is effective for treating primary insomnia. It is worth noting that this studies were of relatively poor quality. The sample sizes were also small. Therefore, further investigations into the diagnosis and treatment of insomnia are warranted.
