Objectives: The purpose of this study was to examine the relationship between pathological patterns and hyperventilation syndrome, using pathological pattern and Nijmegen questionnaires. Methods: 33 healthy adults were asked to complete the Cold-Heat-, Phlegm-, Yin deficiency, and Lao Juan (勞倦)-pattern questionnaires, the Chalder fatigue scale, and the Nijmegen questionnaire at Kyung Hee University Hospital. We performed Pearson correlation analyses between the pathological pattern questionnaires and the Nijmegen questionnaire. The questionnaires were composed of several factors. Therefore, each factor and Nijmegen questionnaire score were also analyzed. Results: All of the pattern questionnaire scores had a positive correlation with the Nijmegen questionnaire score. The phlegm pattern, in particular, and the LaoJuan (勞倦) questionnaire scores had high correlation coefficients. The coefficient for the phlegm pattern was 0.856 and the coefficient for the LaoJuan (勞倦) pattern questionnaire was 0.855. Conclusions: The results mean that the pathological pattern questionnaires could be one of the reference materials to evaluate hyperventilation syndrome. Furthermore, improvement of pathological patterns may be helpful for treating hyperventilation syndrome, together with conventional therapies including breathing training.

Purpose: This study aimed to explore the association of ${\beta}-catenin$ expression pattern with pathological response after neoadjuvant chemotherapy in breast cancer (BC) patients. Materials and Methods: In this retrospective exploratory study, data for 50 BC patients who received neoadjuvant chemotherapy were recorded. ${\beta}-catenin$ expression in tumours was assessed using immunohistochemistry and classified as either membranous or cytoplasmic according to the pattern of staining. Distributions of different clinico-pathological parameters according to ${\beta}-catenin$ expression were assessed using the Chi-square test. Logistic regression analysis was used to assess any relation of the pattern of ${\beta}-catenin$ expression with the pathological response. Results: Cytoplasmic ${\beta}-catenin$ expression was detected in 34% of BCs. Among our cases, 52% were hormonal receptor (HR)-positive, 24% were HER2-positive, 74% were clinical stage III and 74% received both anthracycline and taxane-based chemotherapy. Patients with cytoplasmic expression were more commonly younger than 40 years at diagnosis (cytoplasmic, 41.2% vs. no cytoplasmic expression, 12.1%, p=0.03). By doing t-test, cytoplasmic ${\beta}-catenin$ expression was linked with a higher body mass index compared to membranous-only expression ($mean{\pm}SD$ $33.0{\pm}4.47$ vs. $29.6{\pm}6.01$, respectively, p=0.046). No significant associations were found between ${\beta}-catenin$ expression and other parameters such as HR and HER2 status, or clinical stage. Complete pathological response (pCR) rate was twice as great in patients with membranous expression but without statistical significance (membranous-only, 33.3% vs. cytoplasmic, 17.6%, OR= 2.3, 95% CI= 0.55-9.87, p=0.24). Conclusions: This study suggests that cytoplasmic ${\beta}-catenin$ expression may be linked with lower probability of achieving pCR after neoadjuvant chemotherapy. These data need to be validated in a larger cohort of patients.

Objective: This study was designed to identify and explore the pathological patterns of functional dyspepsia (FD) patients. We also evaluated the usefulness of the Pattern Identification Questionnaire by comparing it with other assessment tools for FD. Methods: We recruited 97 FD patients based on the Rome III criteria for FD diagnosis. The pathological patterns of the subjects were determined by the Pattern Identification Questionnaire. Their dyspepsia-related symptoms were assessed using the Gastrointestinal Symptom Questionnaire (GIS) and the Pyeongwi-san (Pingwei-san) Patternization Questionnaire. Depressive symptoms were evaluated with the Beck Depression Inventory (BDI) and quality of life with the Functional Dyspepsia-Related Quality of Life (FD-QoL) Questionnaire. Tongue coating was measured by the Digital Tongue Diagnosis System (DTDS). Results: The male to female ratio was 1:1.1, and the forties and fifties age groups were largest in number. The spleen deficiency and phlegm-dampness pattern was the most common pattern found among the FD patients. No significant differences in the GIS, BDI, FD-QoL, and DTDS scores were found among the five pattern types. All pattern types showed significant correlation with GIS, Pyeongwi-san Patternization Questionnaire, and FD-QoL scores. Conclusions: Pattern Identification Questionnaire can not only identify the pathological pattern types of FD patients but also evaluate the severity of their symptoms. Compared to conventional assessment tools for FD, it could enable a more dynamic evaluation of FD patients reflecting the severity of dyspeptic symptoms and the quality of life. Further studies on the Pattern Identification of FD patients are anticipated in order to improve the diagnosis and therapy for Korean FD patients.

Objectives: To analyze esophageal cancer incidence and pathological data of Zhongshan in China in 1970-2007, and to provide scientific information for its prevention and control. Methods: From Zhongshan Cancer Registry esophageal cancer incident and pathological data were obtained. Pathological proportions and trends were calculated and analyzed. Results: Although there was a continuously and obviously increasing trend for male incidence rates in 1970-2007 in Zhongshan, squamous cell carcinoma (SCC) and adenocarcinoma (AD) incident proportions during 1990-2007 remained relatively stable. Moreover, SCC was the major pathological type, accounting for 70.6 percent of all new cases, while AD were relatively few and accounted for only 2.66 percent throughout the period. Conclusion: The male esophageal cancer incident pattern in Zhongshan in 1970-2007 was quite different from most other domestic areas. The data suggest that etiological analysis should be enhanced for improved control in Zhongshan.

The clinical and radiographic findings of lung cancer have been well established many journals. Even if the radiographic findings of lung cancer show a typical pattern, the specific cell type of lung cancer sometimes needs to be determined prior to a pathological diagnosis. For example, the usual finding of a squamous cell carcinoma is similar to other cancer types such as an adenocarcinoma or a small cell carcinoma but with a lower incidence. Therefore, it should not be used to make a diagnosis of the cell type prior to a pathological diagnosis. Many unusual findings of lung cancer, so called atypical pattern have been reported, but atypical findings are widely accepted. The more important thing is not to diagnose a specific cell type of cancer but to differentiate it from other benign conditions such as tuberculosis, fungal infections or organizing pneumonia. This paper presents typical information of the cell type of lung cancer along with the atypical radiographic findings.

In order to establish the diagnostic indices of skin diseases, some physiological and pathological concepts of interstices(腠理) were researched based on , and western dermatology with etymological analysis. As physiological indices for diagnosis of skin diseases, measurement of epidermis and dermis using ultrasonogram in the zhongwan and dachui's location. And for grading looseness and fineness of interstices with 3 unsound groups, measuring numbers and sizes of sweat pores in each point's 1 cm diameter circular area using comparative method and palpation assessment. Another index is superficial temperature. As pathological indices for diagnosis, validating volumes of dead skin cells and grading degrees of atrophy and degeneration of skin lesion. And as supplementary measures, absorptive degrees of cosmetics on face should be recorded according to 3 grades. These diagnostic indices can contribute to establishment of standard pattern identification and prescription of skin diseases through converting anatomical cognizance into classical concepts of interstices objectively.

Objectives : The purpose of this paper is to understand the meaning of Yangmingzhongfeng in the Shanghanlun. Methods :Each verse was analyzed, along with consideration of the general context of the Bianyangmingbingmaizhengbingzhi(辨陽明病脈證幷治) chapter where Yangmingzhongfeng is explained. The meaning of Yangmingzhongfeng was discussed with a focus on the intention underlying the contrast between Zhongfeng[中風] and Zhonghan[中寒] within the text. Results : In Yangming Disease, disease patterns that have mutated from other channels are differentiated as either Zhuanshu[轉屬, change of assignment] or Zhuanxi[轉繫, change of connection]. Zhuanshu refers to the situation where symptoms of the original pathological site has disappeared, therefore being assigned to Yangming. Zhuanxi refers to the before-and-after pathological sites being connected. The condition of Zhuanxi is further divided into Taiyin and Yangming, where Zhuanxi Yangming needs to be differentiated from Zhuanshu Yangming in that the cathartic method[下法] cannot be applied even with the existence of constipation, despite it being the indication for such treatment. Yangming Zhongfeng and Yangming Zhonghan are differentiated according to coldness and heat of Zhuanxi Yangming. Conclusions : Yangming Zhongfeng refers to the heat type of Zhuanxi Yangming where the person presents constipation whilst residing exterior pattern. Yangming Disease cannot be understood as having a uniform pattern of Weijiashi-constipation-Shengqitang, and its disease pattern requires a multi-dimensional approach.

Objectives : The purpose of this paper is to find the corresponding pathological situation of the Renmai(任脈), Dumai(督脈), and Chongmai(衝脈) at the Cun(寸), Guan(關), Chi(尺) pulse positions using the Qikoujiudaomai diagnostic method in order to find the pathological pattern of the Eight Extra Meridians. The pulse positions are divided into nine parts, using a three dimensional surface-middle-bottom concept. Methods : Relevant contents in classical texts such as the Maijing, Qijingbamaikao, Zabingyuanliuxizhu, Maiyijianmo were examined, along with previous studies on the topic. The findings were that the Renmai, Dumai, Chongmai examination of the Qikoujiudaomai manifested as floating, tight, firm patterns in the Cun, Guan, Chi positions. Results & Conclusions : n terms of the Renmai, the converging and fast Qi manifested in the three positions as a tight pattern; in the Dumai, the extended and scattering Qi manifested in the three positions as a floating pattern; in the Chongmai, the excessive, solid and full Qi manifested in the three positions as a firm pattern. Once the pathological qi overflows in the 12 meridians, disease happens in the Eight Extra Meridians. As such, disease in the Renmai, Dumai, Chongmai were connected to the main meridians as three branches from one root. Through this study, it could be concluded that diagnosis and acupuncture treatment through the Qikoujiudaomai method is possible.
