Objectives: Shoulder pain is the third most common musculoskeletal complaint that necessitates physician consultation and significantly diminishes patients' quality of life. In this review, we analyzed clinical studies that investigated the use of Korean Medicine for the treatment of shoulder pain. Methods: We searched the online Korean databases, such as KMBase, DBpia, NDSL, RISS, KISS, and OASIS for clinical studies that report the use of Korean Medicine for shoulder pain. We analyzed the included studies with regard to study design, interventions, evaluations, and results. Results: We analyzed data from the following 29 studies: 14 clinical trials (which included 9 randomized controlled trials) and 15 observational studies (which included 11 case reports). In this review, we observed that post-stroke shoulder pain was the most common cause of shoulder pain, which was reported in 13 out of 29 studies (44.8%), although in actual clinical practice, patients are more likely to present with primary shoulder pain. Most included studies (72.4%) reported manual acupuncture as the most common intervention for shoulder pain. More than 50% of the studies used range of motion (58.6%) and the numeric rating scale (51.7%) to evaluate shoulder function and pain, respectively. Although the result was not statistically significant in all included studies, most studies concluded that Korean Medicine could be considered an effective treatment option in patients with shoulder pain. Conclusions: Based on analysis of studies included in this review, Korean Medicine can be considered useful clinical treatment for shoulder pain.
Objectives This study is aimed to identify and evaluate the already developed clinical practice guidelines (CPGs) of temporomandibular disorders (TMD) and contribute to making decisions in developing Korean medicine CPG of TMD. Methods We searched electronic database and selected CPGs of TMD according to the inclusion and exclusion criteria. Then, we made appraisal of selected CPGs by using AGREE II (Appraisal of Guidelines for Research & Evaluation II). Results Four CPGs are included and appraised with AGREE II. Among 6 domains of AGREE II, all CPGs failed to score over 60% in four domains. Only one CPG mentioned acupuncture as an adjunctive treatment for myofascial TMD. Conclusions It is difficult to indicate that included CPGs are with sufficient quality to recommend and it appears not to be appropriate to apply these already developed CPGs in Korean medicine clinical fields. Therefore, developing a new Korean medicine clinical practice guideline of TMD is required.
Objectives: This study aimed to learn what should be considered in the Guidelines of Clinical Trials with Herbal Medicinal Products for Gastroesophageal Reflux Disease (GERD) by analyzing the existing guidelines and clinical trials.Methods: The development committee searched the existing guidelines for herbal medicinal products or GERD. Then, clinical trials related to GERD using herbal medicine were selected. The chosen trials were analyzed in terms of their inclusion and exclusion of participants, intervention, comparators, outcome, and trial design. Then, we compared the results of the analysis according to the regulations and guidelines of the Ministry of Food and Drug Safety to suggest the issues that we will have to consider when developing the Guidelines of Clinical Trials with Herbal Medicinal Products for Gastroesophageal Reflux Disease (GERD).Results: As a result, few guidelines for GERD and clinical trials with herbal medicinal products were located in the national institution homepage. In addition, 8 articles were found using the following combination of search terms: “Gastroesophageal reflux disease”, “GERD”, “herbal medicine”, “herbal therapy”, “Korean Medicine”, “Traditional Chinese Medicine”, and “TCM”. Even though all trials had their own unique research questions, all studies were performed using a randomization method. Most trials included participants with reflux esophagitis, but two trials targeted proton pump inhibitor-refractory GERD. The type of intervention varied, such as decoction, granules, and capsules. Additionally, individualized herbal medicines were used in two studies. Comparators were diverse, such as placebo, Western medicine, and electro-acupuncture. The most frequently used outcome for efficacy was the effectiveness rate. In addition, the outcome for evaluating quality of life, esophageal mucosa and pressure, esophageal acid reflux, and recurrence rates were used. Safety was investigated by recording adverse events and carrying out laboratory tests.Conclusions: We identified some issues by reviewing the existing guidelines and comparing them with clinical trials for GERD and herbal medicinal products. These results will be utilized for developing the Guidelines of Clinical Trials with Herbal Medicinal Products for Gastroesophageal Reflux Disease (GERD).
Bambusae caulis in Liquamen is one of the important herbal medicine produced by heating bamboo indirectly and is used for treatment of stroke, hypertension, and diabetes etc. Recently the mechanism of clinical effects on Bambusae caulis in Liquamen has been studied. This experiment was conducted to confirm the clinical effects of Bambusae caulis in Liquamen on type 1 diabetes and its related mechanism. We divided C57BL/6 mice into 3 groups and induced them to be type 1 diabetes by injection of streptozocin into peritoneum. The dosage of each group was 150 mg/kg once only, 140 mg/kg once only and 40 mg/kg for 5 days respectively. The two groups injected streptozocin for once took orally Bambusae caulis in Liquamen after the induction of diabetes, and the other one group was given Bambusae caulis in Liquamen during the diabetes inducing period. As the result, the two diabetes-induced groups showed blood glucose decreasing effect by Bambusae caulis in Liquamen on an average, but they didn't show the signiftcant differences statistically. But Bambusae caulis in Liquamen showed the anti-diabetic effect suppressing blood sugar rising trend during the diabetes inducing peried (P<0.05). The anti-oxidative effect of Bambusae caulis in Liquamen was measured with the hypoxanthine/xanthine oxidase (HX/XOD) system. The quantity of ROS was measured using DCFDA reagent indirectly. As the result, $10\%$ solution of Bambusae caulis in Liquamen showed anti-oxidative effect by scavenging $93.4\%$ superoxide as compared with control group. It is suspected that the anti-oxidative effect of Bambusae caulis in Liquamen suppressed the increase of blood glucose in the diabetes-inducing group. These results could be useful data to understand the effect of Bambusae caulis in Liquamen on type 1 diabetes and type 1 diabetes developing because ROS were closely connected with the induction and complications of diabetes.

Qi is in the capacity of pivotal element to describe the life, based on the principles of remedy such as Qigong, meridian pathways, acupuncture, moxibustion and herbal medicine. The purpose of this study was to identify the status of course offered Qigong and Qigong-related clubs in 11 college of oriental medicine. For survey courses offered Status of Qigong in 11 college of oriental medicine, I checked its homepage in august 2008. And about the facts that I could not verify information from the homepage, I obtained through the phone manner. For survey Qigong-related clubs in 11 college of oriental medicine, I phoned the president of union clubs and found out Qigong-related clubs. And then I phoned the presidents of Qigong-related clubs that consented before the fact, investigated the overall situation of clubs. Nine out of 11 college of oriental medicine offered course of Qigong. All of them are opened as major in a premedical course. Six universities have practical training. Six out of 11 college of oriental medicine had Qigong-related clubs. And the number of club is 12. The number of club in Daeguhaany university, 4, is the most. The number of membership of club in Daeguhaany university, 61, is the most too. Most of them are co-majoring both Jung-gong and Dong-gong. It is considered that in lecture of Qigong, It is in a need of lecturing in a regular course with clinical contents, rather than lecturing in a premedical course with basic contents. Of spontaneous club activities, after graduation so that they can get practical help for future. I think from now on we need to investigate deeply practical rate of satisfaction and the present condition of clubs.
Objectives : This study is to examine the effects of moxibustion at Junggeuk(CV3), Singwol(CV8) on women's urinary incontinence and quality of life. The study is a research based on the non-equivalent control group pretest-posttest design. Methods : The subjects of the study were 45 women who were using either of 2 health clinics located in Ulsan. They were sampled in accordance with predetermined standards and then divided into the experimental and control groups, respectively consisting of 22 and 23 members. In treating those women through moxibustion, this researcher applied 2 sheets of 'shingigu' to each of the women on 40 min, per time basis. This experiment was conducted 6 times in total for 2 weeks on every two day basis. Data from all of the measurements were statistically processed and analyzed using SPSS/WIN 12.0. Demographic characteristics of the subjects were examined and indicated in frequency and percentage. The homogeneity test of the two groups was conducted using $x^2$-test, Fisher's exact test, t-test and Mann-Whitney U Test. Hypotheses set for the study were verified through t-test and Mann-Whitney U Test. Results : The experimental group who take moxibustion will be lower in the severeness of urinary incontinence than the control group who do not was supported(p<0.001). 2. The experimental group who take moxibustion will be higher in score for life quality than the control group who do not was supported(U=42.00, p<0.001). Conclusions : These findings suggest that moxibustion can be an effective intervention for women having urinary incontinence because it treats the symptom with no adverse effect and it is non-invasive and easily applicable.

This study evaluated the motion of tumors during the entire period of therapy and the accuracy of radiosurgery among forty eight lung tumor patients who were underwent radiosurgery using the CyberKnife Synchrony Respiratory Tracking System. The motion of lung tumor was measured by the coordinates of a gold acupuncture needle inserted into the tumor or the area around the tumor using the CyberKnife image guided system. Then the accuracy of radiosurgery was evaluated based on the error of correlation computed with the motion tracking system. The lung tumor motion is Cranio-Caudal direction by an average of $2.63{\pm}1.87\;mm$, moved left-right direction by $1.13{\pm}0.71\;mm$, and anterior-posterior direction by $1.74{\pm}1.16\;mm$. The degree of rotational movement was $1.66{\pm}1.66^{\circ}$ on X axis, $1.20{\pm}0.97^{\circ}$ on Y axis, and $1.18{\pm}0.73^{\circ}$ on Z axis. The vector of translation movement was measured to be $3.78{\pm}2.00\;mm$ on the average. The results show that directions of Cranio-Caudal(p < 0.001), anterior-posterior direction(p < 0.029), and three dimensional vector value(p < 0.002) showed statistical significance, because the lower side of tumor showed more intensive movement compared to the upper side of tumor. The radiosurgery was carried out by compensating the motion of tumor after accurate investigation of the correlation error with the average of $0.95{\pm}0.62\;mm$ during the lung tumor radiosurgery with the CyberKnife Synchrony Respiratory Tracking System.
The aim of this study is to report the effectiveness of a traditional Korean medicine treatment for oculomotor nerve palsy induced by traumatic subarachnoid hemorrhage. A 54-year-old male patient with oculomotor nerve palsy induced by traumatic subarachnoid hemorrhage after a traffic accident was treated with Korean medicine, including acupuncture, electroacupuncture, sweet bee venom pharmacoacupuction, moxibustion, and herbal medicine. The effect of treatment on symptoms - ptosis, and eye movement - was evaluated using a ratio of eye opening and eye movement between the paralyzed eye and the normal eye. After 41 days of treatment, the clinical symptoms had improved. The ptosis and eye movement started to show improvement from day 20; at the time of discharge, ptosis had improved by more than 50%, and eye movement showed some improvement as well. This study suggests that Korean medicine may be an effective treatment for oculomotor nerve palsy induced by traumatic subarachnoid hemorrhage.
Objectives: The purpose of this study is to investigate safety of postpartum herbal medicine by assessing the effect of taking herbal medicine of postpartum period on liver function. Methods: A retrospective chart review was conducted on 167 mothers who underwent liver function tests (LFT) within 3 months before and after childbirth among mothers who gave birth at ○○ Hospital between January 1, 2016 and May 31, 2018. Mothers with abnormally elevated LFT during pregnancy were excluded. Among 167 women, 6 women are herbal-medicine-group took herbal medicine for 5-6 weeks during postpartum period, and 161 patients are general -group who did not take herbal medicine. LFT Variation of Subjects before and after childbirth were compared between the two groups. And subjects who had elevated liver levels above the normal range after delivery were classified separately, the characteristics and causes of changes in liver levels were analyzed, and the presence or absence of drug-induced liver damage was confirmed. Results: Among a total of 167 subjects, there were 5 women in the herbal-medicine-group and 150 women in the general-group who had changes in liver values within the normal range after childbirth. Aspartate transaminase (AST) change before and after childbirth in the herbal-medicine-group was 3.40±1.82, and AST change in the general-group was 2.92±8.59, showing no significant difference between the two groups (p=0.901). Increase of Alanine transaminase (ALT) before and after childbirth in the herbal-medicine-group was 5.60±3.65, and ALT change in the general-group was 8.01±11.81, showing no significant difference between the two groups (p=0.651). There were 12 subjects who had elevated AST, ALT above the normal range after delivery, including 1 in the herbal-medicine-group and 11 in the normal mothers group. Valuation of 1 Subject of the herbal-medicine-group before and after delivery was 17 IU/L of AST and 52 IU/L of ALT. Because results of AST, ALT is under the standard to diagnose to liver damage, she was observed without any treatment. However the cause of AST, ALT elevation was not found in the chart, she was receiving treatment for diabetes and hyperlipidemia. The general-group had an average increase of AST 35.64±22.67 IU/L and ALT 53.00±26.80 IU/L. As a result of analyzing the cause, there were direct causes such as autoimmune hepatitis, chronic hepatitis B, and acute pyelonephritis. Abnormal elevations in liver levels were also found in mothers with hypothyroidism, diabetes, and fever of unknown cause, although they were not direct causes. Conclusions: To investigate the safety of taking herbal medicines, we assess the variation in AST and ALT within 3 months before and after delivery in the herbal-medicine-group and general-group. There was no significant difference between two groups.
