Background: The purpose of this study was to assess the effect of our new video-assisted asthma education program on patients` knowledge regarding asthma and asthma control. Methods: Adult asthmatics who were diagnosed by primary care physicians and followed for at least 1 year were educated via smart devices and pamphlets. The education sessions were carried out three times at 2-week intervals. Each education period lasted at most 5 minutes. The effectiveness was then evaluated using questionnaires and an asthma control test (ACT). Results: The study enrolled 144 patients (mean age, 56.7±16.7 years). Half of the patients had not been taught how to use their inhalers. After participating in the education program, the participants` understanding of asthma improved significantly across all six items of a questionnaire assessing their general knowledge of asthma. The proportion of patients who made errors while manipulating their inhalers was reduced to less than 10%. The ACT score increased from 16.6±4.6 to 20.0±3.9 (p<0.001). The number of asthmatics whose ACT score was at least 20 increased from 45 (33.3%) to 93 (65.3%) (p<0.001). The magnitude of improvement in the ACT score did not differ between patients who received an education session at least three times within 1 year and those who had not. The majority of patients agreed to the need for an education program (95.8%) and showed a willingness to pay an additional cost for the education (81.9%). Conclusion: This study indicated that our newly developed education program would become an effective component of asthma management in primary care clinics.

Azathioprine is widely used as an immunosuppressive drug in infiammatory bowel disease, many autoimmune disease and after organ transplantation to avoid rejection. Azathioprine has adverse reactions like hepatotoxicity. We report a case of azathioprine induced cholestatic hepatitis in patient with bronchiolitis obliterans organizing pneumonia(BOOP). A-37-year old woman was admitted because of pruritus and jaundice. She took transbronchial lung biopsy, bronchoalveolar lavage for cough, dyspnea and GGO patterns on chest computed tomography(CT) scan before she admitted. And it was revealed that she had BOOP. So she had been followed and treated for BOOP with prednisolone from 23th Nov 2012 and azathioprine from 8th Jan 2013. 42 days after taking Azathioprine, routine blood test was taken. Serum bilirubin, alkaline phosphatase(ALP), aspartate transaminase(AST), and alanine aminotransferase(ALT) was elevated(Bilirubin 4.4mg/dL, AST 75IU/L, ALT 104IU/L) and. Other laboratory test, including prothrombin time, serum albumin, and serum protein were within normal range. There was no history of alcohol abuse or herbal medication intake at this period. To exclude other reasons for hepatotoxicity, serological test was performed. The patient tested to negative for Hepatitis A, B, and C as well as for other markers of autoimmune hepatitis. CT scan showed hepatomegaly with lymph node enlargement and there was no evidence of bile duct obstruction. And TPMT(thiopurine methyltransferase) genotyping was done and revealed to be wild type. Azathioprine was stopped and she was monitored for laboratory changes. Because it was regarded as azathioprine induced cholestatic hepatitis and jaundice, we considered not to do liver biopsy. Day 55 after starting azathioprine therapy, total bilirubin reached peak (12.3mg/ dL). The patient was discharged on day 63 with cholestatic parameters of 115U/L(ALP), 36U/L(γ-GT), and 11.5mg/dL(total bilirubin). After 2 months, total bilirubin was decreased to normal(0.8mg/dL). Treatment of BOOP has been continued only with oral steroid.

Protein tyrosine phosphatases (PTPs) are pivotal regulators of key cellular functions, including cell growth, differentiation, and adhesion. Previously, we reported that leukocyte common antigen-related (LAR) tyrosine phosphatase promotes osteoblast differentiation in MC3T3-E1 preosteoblast cells. In the present study, the mechanism of the regulatory action of LAR on osteoblast differentiation was investigated. The mineralization of extracellular matrix and calcium accumulation in MC3T3-E1 cells were markedly enhanced by LAR overexpression, and these effects were further increased by treatment with an MEK inhibitor. In addition, LAR overexpression dramatically reduced extracellular signal-regulated kinase (Erk) activation during osteoblast differentiation. In contrast, a marginal effect of the inactive LAR mutant on Erk activation was detected. Expression of osteoblast-related genes such as ALP, BSP, DLX5, OCN, and RUNX2, was increased by LAR overexpression during osteoblast differentiation. On the basis of these results, we propose that LAR functions as a positive regulator of osteoblast differentiation by modulating ERK activation. Therefore, LAR phosphatase could be used as a novel regulatory target protein in many bone-associated diseases, including osteoporosis.

Percutaneous transhepatic biliary catheterization (PTC) has not only been increasingly used in the localization of benign and malignant lesions, but it is also considered rapid, safe and effective method to establish internal and external drainage for decompression of biliary obstructions. Infections and granulomas at the catheter entry site can occasionally develop, but are easily managed. However, such technique, when used both for obtaining malignant cells for diagnosis and for percutaneous decompression of the biliary tract can exposure the patient at risk for dissemination of the tumor along the catheter tract. This rare complication has been observed in a patient who underwent percutaneous transhepatic biliary drainage (PTBD) for malignant biliary tract obstruction. Although tumor cell seeding along the catheter tract is a very rare complication, we think that PTBD should be avoided when curative resection is planned.

Objectives: This study aimed to examine the difference of external appearance measurements in subjects of different regional lineages as subgroups within the Tae-eumin Sasang grouping. Methods: We chose 51 Tae-eumin subjects diagnosed by Korean Sasang constitutional medical doctors aided by voice analysis. The subjects were divided into two groups, the northern and southern lineages, by an expert on facial characteristics of the two lineages. We took pictures of their frontal and lateral views by Martin's method, measured projected length of face with the Facial Feature Measurement Program, and analyzed anthropometric facial differences between the northern and southern types. Results: Results show differences between the northern and southern types. First, the northern type of face has bigger measurements than the southern type on the frontal face. Second, the northern type of face has higher measurements of "height", which means distance from pupil to a specific measurement point, than the southern type on the frontal face. Third, on the frontal face, the northern and southern types have differences with respect to eyebrow, point of sellion, and eye. Fourth, on the side face, the northern and southern types have differences in lip, mandible and ear. Conclusions: We found our anthropometric facial measurements of the northern and southern lineages to be in accordance with previous literature. Knowledge of the differences between the northern and southern lineages can be a hint in constitutional diagnosis when differentiation is clinically confusing.

<P>Adipocyte differentiation can be regulated by the combined activity of protein tyrosine kinases (PTKs) and protein tyrosine phosphatases (PTPs). In particular, PTPs act as key regulators in differentiation-associated signaling pathways. We recently found that receptor-type PTPμ (RPTPμ) expression is markedly increased during the adipogenic differentiation of 3T3-L1 preadipocytes and mesenchymal stem cells. Here, we investigate the functional roles of RPTPμ and the mechanism of its involvement in the regulation of signal transduction during adipogenesis of 3T3-L1 cells. Depletion of endogenous RPTPμ by RNA interference significantly inhibited adipogenic differentiation, whereas RPTPμ overexpression led to an increase in adipogenic differentiation. Ectopic expression of p120 catenin suppressed adipocyte differentiation, and the decrease in adipogenesis by p120 catenin was recovered by introducing RPTPμ. Moreover, RPTPμ induced a decrease in the cytoplasmic p120 catenin expression by reducing its tyrosine phosphorylation level, consequently leading to enhanced translocation of Glut-4 to the plasma membrane. On the basis of these results, we propose that RPTPμ acts as a positive regulator of adipogenesis by modulating the cytoplasmic p120 catenin level. Our data conclusively demonstrate that differentiation into adipocytes is controlled by RPTPμ, supporting the utility of RPTPμ and p120 catenin as novel target proteins for the treatment of obesity.</P>

<P>Mesenchymal stem cells (MSCs) are multipotent adult stem cells that can differentiate into a variety of mesodermal-lineage cells. MSCs have significant potential in tissue engineering and therapeutic applications; however, the low differentiation and proliferation efficiencies of these cells in the laboratory are fundamental obstacles to their therapeutic use, mainly owing to the lack of information on the detailed signal-transduction mechanisms of differentiation into distinct lineages. With the aid of protein-tyrosine-phosphatase profiling studies, we show that the expression of leukocyte common antigen related (LAR) tyrosine phosphatase is significantly decreased during the early adipogenic stages of MSCs. Knockdown of endogenous LAR induced a dramatic increase in adipogenic differentiation, whereas its overexpression led to decreased adipogenic differentiation in both 3T3-L1 preadipocytes and MSCs. LAR reduces tyrosine phosphorylation of the insulin receptor, in turn leading to decreased phosphorylation of the adaptor protein IRS-1 and its downstream molecule Akt (also known as PKB). We propose that LAR functions as a negative regulator of adipogenesis. Furthermore, our data support the possibility that LAR controls the balance between osteoblast and adipocyte differentiation. Overall, our findings contribute to the clarification of the mechanisms underlying LAR activity in the differentiation of MSCs and suggest that LAR is a candidate target protein for the control of stem-cell differentiation.</P>
