Background: CD44v6 (CD44 variant exon 6) is the chief CD44 variant isoform regulating tumor invasion, progression, and metastasis. The prognostic value of CD44v6 expression in non small cell lung cancer (NSCLC) has been evaluated in many studies, but the results have remained controversial. Thus, we performed a meta-analysis of currently available studies to investigate the prognostic value of CD44v6 expression in NSCLC patients and the relationship between the expression of CD44v6 and clinicopathological features. Materials and Methods: Two independent reviewers searched the relevant literature in Pubmed, Medline and Embase from 1946 to January 2014. Overall survival (OS) and various clinicopathological features were collected from included studies. This meta-analysis was accomplished using STATA 12.0 and Revman 5.2 software. Pooled hazard ratios (HRs) with 95% confidence intervals (95%CIs) were calculated to estimate the effects. Results: A total of 921 NSCLC patients from ten studies met the inclusion criteria. The results showed that CD44v6 high expression was a prognostic factor for poor survival (HR=1.91, 95%CI=1.12-3.26, p<0.05). With respect to clinicopathological features, CD44v6 high expression was related to histopathologic type (squamous cell carcinoma versus adenocarcinoma: OR=2.72, 95%CI=1.38-5.38, p=0.004), and lymph node metastasis (OR=3.02, 95%CI=1.93-4.72, p<0.00001). Conclusions: Our results suggested CD44v6 high expression as a poor prognostic factor for NSCLC, and CD44v6 expression is associated with lymph node metastasis and histopathologic type. Therefore, CD44v6 expression can be used as a novel prognostic marker in NSCLC cases.

The RLG (relative length of gut) is 1.52 (n=12) in the sablefish, Anoplopoma fimbria. The digestive tract has five or six pyloric caeca in the posterior region of stomach. Morphology of mucosal fold is unbranched type in the esophagus and stomach, but branched type in the intestine. The histological structure of digestive tract can be divided into mucosal layer, submucosal layer, muscular layer and serous membrane in the cross section. In the esophagus, mucosal epithelial layer is a simple, and consists of ciliated columnar epithelia and mucous cells. In the stomach, gastric gland of mucosal epithelial layer is a tubular, and is composed of chief cell, parietal cell and mucin secreting cell, which is columnar and contained secretory granules of red and blue colors in the AB-PAS (pH 2.5) reaction. In the intestine, mucosal epithelial layer is a simple, and consists of ciliated columnar epithelia and goblet cells. The submucosal layer is composed mainly of collagen fibers, and well developed in the esophagus. And the muscular layer of digestive tract is divided into longitudinal and circular muscle layer, and well developed in the stomach. The liver is composed of numerous lobular structure and bile canaliculi. Stainability of hepatocyte cytoplasm was eosinophilic, and nucleus and nucleolus showed basophilic in the H-E stain. The pancreatic tissue was scattered in the fatty tissue near the digestive tract, and acinar gland consisting of numerous exocrine cells. And cytoplasmic stainability of exocrine cell was basophilic, and contained numerous zymogen granules of eosinophilic in the H-E stain.

Background: Lung cancer continues to increase worldwide. Also, the proportion of female patients incease and adenocarcinoma is the predominant histological type among lung cancer in many western countries. So, we studied these current trends of lung cancer by clinical approach of recent patients from our department Method: We conducted a retrospective analysis on 212 subjects who were diagnosed with lung cancer at the department of chest medicine in National Medical Center between January 1990 and July 1996. The contents of analysis were patient's profile, clinical manifestation, smoking habits, accuracy of diagnostic methods, histological cell type, staging and treatment, etc. Results: The results were as follows. 1) The ratio of male to female was 5.2 : 1. The peak incidence of age was 7th decade(35.4%). 2) Chief complaints were cough, dyspnea and chest pain, etc. The most common duration of symptoms before the first admission was less than 3 months(57.7%). On the other side, duration more than 1 year represented 6.5%. The early diagnosed patients has been increased from the 1980s. 3) Smokers among the total patients were 77.2%. The proportion of smokers in sqamous cell carcinoma, small cell carcinoma and adenocarcinoma were 88.4%, 85.7% and 55.7%, respectively. Smoking history and histological cell type were correlated in squamous and small cell carcinoma. 4) Squamous cell carcinoma is still the predominant histological type (44.8%), but, adenocarcinoma increased more than the previous study(30.7%). The other histological types were small cell carcinoma(17.0%) and large cell carcinoma(3.8%) in order of their proportions. 5) The accuracy of diagnostic methods were as follows: sputum cytology 75.3%, bronchoscopic biopsy 65.7%, lymph node aspiration cytology 95.8%, percutaneous lung aspiration cytology 94.6% and open lung biopsy 100%. The general accuracies of diagnostic methods were improved than previous studies. 6) Performance status scales on admission were relatively good. After diagnosis, chemotherapy and/or radiotherapy were undertaken in 69.3% of the patients, and only 7.5% of the patients were operated. Conclusion: In our study, squamous cell carcinoma is still the predominant histological cell type, but, adenocarcinoma continues to increase. Because adenocarcinoma is less correlated with smoking habits, further evaluation of other carcinogens than smoking is requested. Screening and early diagnosis of lung cancer is important for good performance status scales in spite of advanced stages. But, we think that the prevention, for example, stop smokings is more important as because of no perfect treatment for lung cancer.

We report a female small cell lung cancer patient in the extensive stage(T3N3Mx). After 6 cycles of chemotherapy combined radiation therapy, she received inpatient Korean medical care including herbal medicine, acupuncture therapy and concurrent western oral medications of opioid analgesics and anti-anxiety agent. The chief complaint was right side thoracic wall pain which had started after chemotherapy and was not effectively controlled by analgesics. For this condition, we treated her with 2Hz of constant electrical stimulation on Jiaji (Ex-B2) points T5-T7 laterally (right) using three needles for 20 minutes once a day for 9 days. With every session of electrical acupuncture treatment, thoracic pain decreased acutely. Korean medicine treatments including Jiaji (Ex-B2) point stimulation might be tried for lung cancer patients with uncontrolled thoracic pain at least for the acute analgesic effect.

Background and Objective : Laryngeal Papillomatosis (LP) is the most common benign neoplasm of the larynx, but it tend to recur and it makes eradicating difficult. Meticulous $CO_2$ laser excision has been the most effective treatment to date. This article analyzes the clinical feature and therapeutic results of 42 LP patients who were undergone $CO_2$ laser excision. Methods : Forty two patients with recurrent LP were treated with $CO_2$ laser. And their medical records were reviewed retrospectively. Demographics, chief complaints at onset, initial distribution of papillomas, number of operations performed on each patient, and current results were evaluated. Results : Male in their twenties and forties are dominant in number in patient number. Most common site was anterior one thirds (69%) of glottis area (86%). LP recurred in 17 cases (40%), and in 4 cases, the lesion extended over the original margin. Patients were undergone surgery $1.62{\pm}0.87$ times, $2.53{\pm}0.72$ in recurred cases. Mean relapsing time was 6 momths (from 1momth to 8years). Ant. laryngeal web occurred in 2 cases (4.8%) and 1 case was combined with squamous cell carcinoma. Conclusion : Meticulously performed $CO_2$ laser excision can achieve significant voice and airway improvement and clinical cures. The $CO_2$ laser through microdirect laryngoscopy allows more precise and bloodless removal of papillomas.

The obtained results are summarized as follows 1. New findings are reporting year by year as for the study related to Anti-inflammatory mechanism of Bee Venom therapy. 2. The Anti-inflammatory effect of Bee Venom therapy is achieved through counterirritation, stimulations to adrenal cortex, immuno-regulation, antioxidation, removal of free radicals, modulation of AGP gene induction. 3. The chief components of Bee Venom related to Anti-inflammatory effect are Melittin, MCD peptide, Apamin, Adolapin etc. 4. Melittin binds to secretory phospholipase A2 and inhibits its enzymatic activity. 5. Melittin blocks neutophil O2-production. 6. MCD peptide(Peptide 401) stimulates the mast cell secrets histamine, Anti-inflammatory effect caused by this is 'conterirritation'. 7. Melittin & Apamin have an anti-inflammatory effect by inducing cortisone secretion. 8. MCD peptide & Apamin increase immunologic fuction by stimulating hypophysis & adrenal cortex and have an anti-inflammatory effect by inhibiting synthesis of prostaglandin from arachidonic acid. 9. Adolapin have an anti-inflammatory effect by inhibiting COX. 10. Bee Venom have an anti-inflammatory effect by suppressing AGP($\alpha$-acid glycoprotein). 11. Bee Venom have an anti-inflammatory effect by inhibiting NO, iNOS, PLA2, COX-2, TNF-$\alpha$, IL-1, NF-${\kappa}B$, MAP kinase.

Background. Ever since the first report of deltopectoral flap in pharyngo-esophageal reconstruction in 1965, various methods of flap reconstruction have been introduced, allowing surgical eradication of tumors that were once thought to be inoperable. Despite these advancement, many literatures emphasize distant metastasis and second primary malignancies as the most important factors that contribute to the low 5-year survival rate of the patients. Specific consensus about defining second primary cancer is still debatable, due to small number of reports regarding second primary tumors arising in flaps used for reconstruction of defects in the head and neck region. Case. We report a case of a 72-year-old male patient who, under the diagnosis of hypopharyngeal cancer, underwent total laryngectomy with partial pharyngectomy, extended right radical neck dissection with extended left lateral neck dissection, right hemithyroidectomy and radial forearm free flap reconstruction on June 16, 2003. After 37 cycles of radiation therapy, the patient exhibited no sign of recurrence. The patient revisited our department on June 14, 2016 with chief complaint of dysphagia that started two months before the visit. Radiologic studies and histology revealed squamous cell carcinoma in neopharynx, one that had been reconstructed with forearm free flap. Conclusion. Until now, only a handful of reports regarding patients with second primary cancer in reconstructed flaps have been described. Despite its rarity, diagnostic criteria for second primary cancer should always kept in consideration for patients with recurred tumor.

Objectives : The purpose of this study was to analyze the trend of clinical research on quantitative indicators of Mibyeong in traditional chinese medicine(TCM). Method : The journal search was performed using china national knowledge infrastructure(CNKI) database. Our inclusion criteria were as following: TCM clinical researches for quantitative indicators of Mibyeong. Exclusion criteria were as following: non-TCM clinical researches, used intervention methods. Results : Eleven clinical researches were analyzed in this study. Four of these researches classify the Mibyeong as a type of pattern identification(PI) and studied the characteristics of the PI quantitative indicators. Mibyeong diagnosis was done through guidelines and questionnaires, each was used at a similar rate. Quantitative indicators mentioned in the selected researches were blood indices, nailfold capillary, complexion, color of tongue substance and coating, pulse wave diagrams and heart rate variability. Among them, seven researches related to blood indices were the most. Blood indicators include whole-blood viscosity, plasma viscosity, fibrinogen, packed cell volume(Hct), triglycerides, total cholesterol, HDL-C, LDL-C, glucose, BUN/CREA, luteinzing hormone, estradiol, follicle stimulating hormone, IgA, IgG, etc. Conclusions : Based on this results, in combination with western medicine, it seems necessary to try to interpret the Mibyeong in more various ways. Even if the same Mibyeong, it is necessary to identify the index which changes according to the PI or chief complaint, and to set the Mibyeong standard corresponding thereto.

Insulinoma is a rare tumor, occurring more often in women and in the older age range. Eighty percent of patients have a single benign tumor, usually 2cm in diameter, located with about equal frequency in body, head or tail of pancreas and amenable to surgical cure. About 10% have multiple tumors. The remaining 10% of patients have metastatic malignant insulinoma. The symptom of insulinoma is characterized by the periodic attack of hypoglycemia of blood sugar level below 50mg%, by fasting or exertion, and rapid relief of symptom by oral or intravenous administration of glucose. Symptom often lead to misdiagnosis as a neurologic or psychiatric disorder. A case described by authors was 44-year old female with the chief complaints of the loss of consciousness, epileptic seizure although she has been treated by anticonvulsants. Serum blood sugar and insulin level during fasting sugested insulinoma but abdominal computed tomography shows no definitive mass in pancreas. Celiac angiography revealed insulinoma. She transfered to the defartment of General Surgery and was performed enucleation. Microscopic findings shows the islet cell tumor of pancreas. A brief review of the literature was made.
