Objectives: To describe a clinical case of a patient with chronic fatigue syndrome (CFS) who was cured using indirect moxibustion. Methods: A male patient with severe CFS was treated with mainly indirect moxibustion (KI1, CV4 and CV8). The clinical outcome was observed by self-reporting, both visual analogue scale (VAS) and numerical rating scale (NRS). Results: The patient's symptoms matched the criteria for CFS diagnosis. His symptom differentiation was the "Yang deficiency of spleen and kidney". The fatigue feeling and related-symptoms were radically reduced by 14-day treatment. The VAS and NRS score changed from 8.5 and 70 to 3.5 and 35, respectively. Conclusions: This case report provides information on the potential of moxibustion therapy and its application for CFS and fatigue-associated disorders.

Systemic lupus erythematosus is a disease of unknown etiology that affects many organ system and is characterized by the presence of multiple autoantibodies that participated in immunology mediated tissue injury. A 36 years-old female patient was admitted to ward due to high fever and erythematous rash on face and hole body. She exhibited itching sense, joint pain, nausea, fatigue, sensitivity to light. The homatologic finding revealed anemia, decrease of lymphocyte, low platelet count, but LE cell, Anti nuclear antibody(ANA) were negative. In the point of Differentiation of Syndrome(辨證), SLE can be thought to be a category of Seasonal febril disease(溫病). This subject diagnosed as Domination of intense evil heat(熱毒熾盛), and was administrated with Chungonpadocyem-gamibang(淸瘟敗毒飮加味方). The clinical and laboratory findings of our patient were improved by herb medication, acupuncture therapy and general supportive measure.

기저세포양 편평세포암(basaloid squamous carcinoma)은 상부 기도소화기계에 발생하는 드문, 악성도가 높은 암종으로 침습성 편평세포암(invasive squamous carcinoma)이나 상피내암(carcinoma in situ) 형태의 편평상피암종성분과 밀접하게 혼재되어 있는 기저세포앞종성분(basaloid component)으로 특징 지워질 수 있다. 이런 조직학적 특성에도 불구하고 식도의 선양 낭성암(adenoid cystic carcinoma)이나 선양 낭성 분화를 보이는 암종(carcinoma with adenoid cystic differentiation)과 혼동되어 왔으나, 순수 선양 낭성암은 악성도가 기저세포양 편평세포암보다 낮아감별 진단이 중요하다. 기저세포양편평세포암의 임상적 경과는 식도의 편평세포암과 유사하다. 본 병원에서는 60세 남자의 식도 중간 113 부위에 발생한 기저세포양 편굉세포암을 수술치험하였다.

Granulocyte colony-stimulating factor (G-CSF) is a cytokine secreted by stromal cells and plays a role in the differentiation of bone marrow stem cells and proliferation of neutrophils. Therefore, G-CSF is widely used to reduce the risk of serious infection in immunocompromised patients; however, its use in such patients is limited because of its non-persistent biological activity. We created an N-linked glycosylated form of this cytokine, hG-CSF (Phe140Asn), to assess its biological activity in the promyelocyte cell line HL60. Enhanced biological effects were identified by analyzing the JAK2/STAT3/survivin pathway in HL60 cells. In addition, mutant hG-CSF (Phe140Asn) was observed to have enhanced chemoattractant effects and improved differentiation efficiency in HL60 cells. These results suggest that the addition of N-linked glycosylation was successful in improving the biological activity of hG-CSF. Furthermore, the mutated product appears to be a feasible therapy for patients with neutropenia.

Human eyelid adipose-derived stem cells (hEAs) and amniotic mesenchymal stem cells (hAMs) are very valuable sources for the cell therapeutics. Both types of cells have a great proliferating ability in vitro and a multipotency to differentiate into adipocytes, osteoblasts and chondrocytes. In the present study, we evaluated their stem cell characteristics after long-time cryopreservation for 6, 12 and 24 months. When frozen-thawed cells were cultivated in vitro, their cumulative cell number and doubling time were similar to freshly prepared cells. Also they expressed stem cell-related genes of SCF, NANOG, OCT4, and TERT, ectoderm-related genes of NCAM and FGF5, mesoderm/endoderm-related genes of CK18 and VIM, and immune-related genes of HLA-ABC and ${\beta}$2M. Following differentiation culture in appropriate culture media for 2-3 weeks, both types of cells exhibited well differentiation into adipocyte, osteoblast, and chondrocyte, as revealed by adipogenic, osteogenic or chondrogenic-specific staining and related genes, respectively. In conclusion, even after long-term storage hEAs and hAMs could maintain their stem cell characteristics, suggesting that they might be suitable for clinical application based on stem cell therapy.

One of the goals of stem cell technology is to control the differentiation of human embryonic stem cells (hESCs), thereby generating large numbers of specific cell types for many applications including cell replacement therapy. Although individual hESC lines resemble each other in expressing pluripotency markers and telomerase activity, it is not clear whether they are equivalent in their developmental potential in vitro. We compared the developmental competence of three hESC lines (HSF6, Miz-hES4, and Miz-hES6). All three generated the three embryonic germ layers, extraembryonic tissues, and primordial germ cells during embryoid body (EB) formation. However, HSF6 and Miz-hES6 readily formed neuroectoderm, whereas Miz-hES4 differentiated preferentially into mesoderm and endoderm. Upon terminal differentiation, HSF6 and Miz-hES6 produced mainly neuronal cells whereas Miz-hES4 mainly formed mesendodermal derivatives, including endothelial cells, leukocyte progenitors, hepatocytes, and pancreatic cells. Our observations suggest that independently-derived hESCs may differ in their developmental potential.

Purpose: There are some reports presenting that peripheral blood contain circulating hematopoietic cells as well as, in significantly smaller quantities, mesenchymal stem cells. The purposes of this study is to isolate and characterize circulating mesenchymal progenitor cells with osteogenic potential from human peripheral blood. Methods: Human buffycoat containing mononuclear cells was harvested from peripheral blood of normal persons and isolated using a density gradient centrifugation and serially subcultured in osteogenic media for 1-4 weeks. The proliferation capability, phase-contrast microscopy, transmission electron microscopy, immunophenotype FACS analysis, Alizarin red staining and RT-PCR assays for osteogenic differentiation potential were performed. Results: The phenotype of cultured cells changed from small round or cuboidal cells at passage 1 into large spindle-shaped fibroblastic morphology cells at passage 4. Surface marker expressed CD14, but did not express CD34, CD80, CD83. Strong positive staining was observed for Alizarin reds in osteogenic medium on day 14, Using RT-PCR, the mRNA levels of bone- specific genes, such as ALP, c-bfa-1 and osteocalcin were detected. Conclusion: A new subset of peripheral blood derived progenitor cells described here has the ability to proliferate and differentiate into osteogenic cell lineages in vitro, and to be candidate for regenerative therapy.

Background: A raised carcinoembryonic antigen (CEA) may be associated with significant pathology during the postoperative follow-up of lung adenocarcinoma. Methods: We reviewed the medical records of 305 patients who underwent surgical resections for primary lung adenocarcinoma at a single institution between April 2006 and February 2013. Results: Preoperative CEA levels were significantly associated with age, smoking history, pathologic stage including pT (pathologic tumor stge), pN (pathologic nodal stage) and overall pathological stage, tumor size and differentiation, pathologically positive total lymph node, N1 and N2 lymph node, N2 nodal station (0/1/2=1.83/2.94/7.21 ng/mL, p=0.019), and 5-year disease-free survival (0.591 in group with normal preoperative CEA levels vs. 0.40 in group with high preoperative CEA levels, p=0.001). Preoperative CEA levels were significantly higher than postoperative CEA levels (p<0.001, Wilcoxon signed-rank test). Postoperative CEA level was also significantly associated with disease-free survival (p<0.001). A follow-up serum CEA value of >2.57 ng/mL was found to be the appropriate cutoff value for the prediction of cancer recurrence with sensitivity and specificity of 71.4% and 72.3%, respectively. Twenty percent of patients who had recurrence of disease had a CEA level elevated above this cutoff value prior to radiographic evidence of recurrence. Postoperative CEA, pathologic stage, differentiation, vascular invasion, and neoadjuvant therapy were identified as independent predictors of 5-year disease-free survival in a multivariate analysis. Conclusion: The follow-up CEA level can be a useful tool for detecting early recurrence undetected by postoperative imaging studies. The perioperative follow-up CEA levels may be helpful for providing personalized evaluation of lung adenocarcinoma.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder characterized by motor, cognitive, and psychiatric symptoms, accompanied by marked cell death in the striatum and cortex. Stereotaxic injection of quinolinic acid (QA) into striatum results in a degeneration of GABAergic neurons and exhibits abnormal motor behaviors typical of the illness. The objective of this study was carried out to obtain basic information about whether parthenogenetic mouse embryonic stem (PmES) cells are suitable for cell replacement therapy of HD. To establish PmES cell lines, hybrid F1 (C57BL/6xCBA/N) mouse oocytes were treated with 7% ethanol for 5 min and cytochalasin-B for 4 hr to initiate spontaneous cleavage. Thus established PmES cells were induced to differentiate using bFGF (20ng/ml) followed by selection of neuronal precursor cells for 8 days in N2 medium. After selection, cells were expanded at the presence of bFGF (20 ng/ml) for another 6 days, then a final differentiation step in N2 medium for 7 days. To establish recipient animal models of HD, young adult mice (7 weeks age ICR mice) were lesioned unilaterally with a stereotaxic injection of QA (60 nM) into the striatum and the rotational behavior of the animals was tested using apomorphine (0.1mg/kg, IP) 7 days after the induction of lesion. Animals rotating more than 120 turns per hour were selected and the differentiated PmES cells (1$\times$10$^4$cells/ul) were implanted into striatum. Four weeks after the graft, immunohistochemical studies revealed the presence of cells reactive to anti-NeuN antibody. However, only a slight improvement of motor behavior was observed. By Nissl staining, cell mass resembling tumor was found at the graft site and near cortex which may explain the slight behavioral improvement. Detailed experiment on cell viability, differentiation and migration explanted in vivo is currently being studied.
