Objective： To evaluate the clinical efficacy of electrical stimulation（ES） of auricular acupressure on reducing the ocular symptoms and signs before and after treatment for dry eye. Methods： The inclusion criteria were the tear film break-up time（TFBUT） below 5 s and a Schirmer test-Ⅰ below 5 mm in dry eyes with ocular symptoms for at least 6 months. Subjects were randomized into a treatment group（50 cases） with continuous low frequency ES under auricular acupressure at acupoints and a no ES under auricular acupressure（no-ES, control group, 50 cases） on the same acupoints. Auricular acupressure were stimulated with ES at 4 master points of both ears, which were performed twice a week for 4 weeks at each point for 30 s. The ocular symptoms, the TFBUT, and Schirmer test-Ⅰ were evaluated before and after this procedure. Results： There were significantly better scores in TFBUT（P=0.032）, the Schirmer test-Ⅰ（P=0.044） and ocular symptoms（P=0.029） at 3 months post-treatment in the treatment group than in the control group. The total effective rate in the treatment group was accomplished in 41（82%） of the 50 cases of dry eye. Conclusions： Auricular acupressure with ES at auricular acupoint improves ocular symptoms and signs of dry eye for a period of at least 3 months.

Quantum secure direct communication network with hyperentanglement

引用

Chinese Physics B 2014年第9期23卷 107-111页

作者： Chang Ho hong Jino Heo jong In Lim Hyung Jin Yang Graduate School of Information Management and Security Korea University Center for Information Security Technologies (CIST) Korea University Department of Physics Korea University Graduate School of Information Security (GSIS) Korea University

We propose a quantum secure direct communication protocol with entanglement swapping and hyperentanglement. Any two users, Alice and Bob, can communicate with each other in a quantum network, even though there is no direct quantum channel between them. The trust center, Trent, who provides a quantum channel to link them by performing entanglement swapping, cannot eavesdrop on their communication. This protocol provides a high channel capacity because it uses hyperentanglement, which can be generated using a beta barium borate crystal.

Current status and challenges in sentinel node navigation surgery for early gastric cancer

Chinese Journal of Cancer Research 2017年第2期29卷 93-99页

Although a number of feasibility studies for sentinel node （SN） concepts in gastric cancer have been conducted since 2000, there remains a debate regarding detailed detection techniques and oncological safety. Two important multicenter phase II clinical trials were performed in Japan that used different methods and reached different conclusions; one confirmed acceptable results with a false-negative rate of 7%, and the other showed an unacceptably high false-negative rate of 46.4%. The Sentinel Node Oriented Tailored Approach （SENORITA） trial is a multicenter randomized controlled phase 1/I trial being performed in Korea. Patient enrollment is now complete and the long-term results are currently awaited. Recently, an image-guided SN mapping technique using infrared ray/fluorescence was introduced. This method might be a promising technology because it allows the clear visualization of SNs. With regard to the primary tumor, the non-exposed endoscopic wall-inversion surgery technique and non-exposure endolaparoscopic full-thickness resection with simple suturing technique have been reported. These methods prevent abdominal infection and tumor seeding and can be good alternatives to conventional laparoscopic gastric wedge resection. For indications, SN navigation surgery can be extended to patients who underwent non-curative endoscopic resection. Although a few studies have been performed on these patients, sentinel concepts may be beneficial to patients as they omit the need for additional gastrectomy. SN navigation surgery can lead to actual organ-preserving surgery and plays a key role in improving the quality of life of patients with early gastric cancer in the future.

Development of benthic macroinvertebrates sediment index(BSI) for bioassessment of freshwater sediment

引用

International Journal of Sediment Research 2019年第4期34卷 368-378页

作者： Pil Jae Kim jong Hyeon Lee In Ae Huh Dong soo Kong Department of Life Science Kyonggi University Environmental Health & Safety Research Institute EH R&C CO.Ltd. Water Environmental Engineering Research Division National Institute of Environmental Research

Sediment quality has been evaluated in a variety of ways since the early 1990 s in studies from Europe. In South Korea, most studies have used an indicator value for benthic macroinvertebrates based on water quality, not sediment quality. To date, few studies have examined the biological integrity of benthic macroinvertebrate communities in South Korea. In the current study, the tolerance valency and value in samples and the indicator weight values were measured for 43 benthic macroinvertebrate taxa from 73 sampling units in South Korea from 2014 to 2016. Total organic carbon, the amount of heavy metals, and total ammonia nitrogen were analyzed. The average grade for each pollutant was used as the sediment quality index. A benthic macroinvertebrates sediment index was developed for bioassessment of freshwater sediment. The benthic macroinvertebrates sediment index, which is based on the relative frequency of occurrence of macroinvertebrates, was highly correlated with pollution levels in the sediment. This index can be used in the field to assess the contamination of freshwater sediment. As the sample size was small in the current study and there were taxonomic limitations of Chironomidae larvae,further research is needed to improve the reliability of the benthic macroinvertebrates sediment index.

Synchronous quintuple primary gastrointestinal tract malignancies: Case report

World Journal of Gastroenterology 2017年第1期23卷 173-177页

作者： soo-hong Kim Byung-soo Park Hyun Sung Kim Jae Hun Kim Department of Surgery Pusan National University Yangsan Hospital Department of Surgery Pusan National University Hospital

Multiple primary malignancy is defined as two or more malignancies detected in an individual person. In particular, synchronous quintuple primary malignancy is extremely rare. A 52-year-old male with anal pain and intermittent blood-tinged stool was diagnosed with malignancies in the stomach, jejunum, ascending colon, transverse colon and rectum. He underwent a subtotal gastrectomy, segmental resection of the jejunum and total protocolectomy with end ileostomy. The postoperative pathologic findings were moderate differentiated gastric adenocarcinoma (pT1bN0M0, pStageIA), combined adenocarcinoma and neuroendocrine carcinoma of the jejunum (pT3N0M0, pStageIIA), three mucinous adenocarcinoma of the ascending colon (pT3N0M0, pStageIIA), transverse colon (pT1N0M0, pStageI) and rectum (pT3N1aM0, pStageIIIB). The tumors did not lack MLH-1 and MSH-2 expression, as the markers (bat26, D5S346, bat25, D2S123) suggest MSI-H presence. Adjuvant chemoradiotherapy was started according to regimen, FOLFOX 4 for advanced rectal cancer. Six years post-operation, the patient is currently attending regular follow-ups without recurrence or metastasis.
