1.Primary Perivascular Epithelioid Cell Tumor (PEComa) of the Liver: A Case Report and Review of the Literature.
Korean Journal of Pathology 2011;45(Suppl 1):S93-S97
Perivascular epithelioid cell tumor (PEComa) is a mesenchymal tumor consisting of distinctive perivascular epithelioid cells, and is commonly detected in the uterus. The liver is an uncommon site for primary PEComa. In this study, we report a case of primary hepatic PEComa in a 36-year-old woman. Upon gross examination, the tumor was a well-defined, brownish solid mass, measuring 6.5x5.2x4.5 cm. Microscopically, the tumor consisted largely of epithelioid cells and some spindle cells with a clear to eosinophilic cytoplasm and a rich network of delicate capillaries in the stroma. With the exception of their relatively large size and microscopically sinusoidal infiltrative growth pattern, all other histopathologic features of the tumor were consistent with their being benign. The tumor cells were positive for human melanoma black-45 and smooth muscle actin, and negative for cytokeratin-cocktail and c-kit.

3.Development of the high voltag egenerator for the defibrillator
Chinese Medical Equipment Journal 2003;0(S1):-
This paper presents a high voltage generator for the defibrillator.Its principle and design method are introduced.The high voltage generator is the core part of the defibrillator which is necessary toany hospital.There is nodomestic-patented defibrillator by now and published paper specialized in the principle and design method of the high voltage generator for the defibrillator.

Objective According to Kaschin-Beck Disea se monitory standardization that had been adjusted by our country,we monitored the state of Kaschin-Beck Disease in Gansu province.Methods So as to understand change of illness,we took methods of epidemiological investigation,clinical examination and X-ray diagnosis.Results It is not detected in the clinical that patient suffered from more than I of KBD among 7~12 years old in Qingyang monitory netw ork.X-ray detectable rate is 3%,but 12 cases patients were showed in Zhangjiach uan.X-ray detectable rate is 22.22%.Conclusions Illness was showed steady state and was con trolled in Qingyang region,but illness recurred clearly in Zhangjiachuan region.

PURPOSE: This study was done to identify the effectiveness of the 'intervention - mother's recorded song' on low-birth weight infants in an neonatal intensive care unit (NICU). METHODS: This study was conducted with a nonequivalent control group pre-posttest quasi-experimental design and the participant group was low-birth weight infants who were admitted to the NICU. Forty-eight infants, 24 in each from two groups, the experimental and control group, participated in the study. RESULTS: For physical response according to vital signs, there were no significant statistical differences in heart rate, respiration rate and pulse oximetry saturation between the experimental group and the control group. For behavioral state, there was a significant statistical difference between the experimental and control group. CONCLUSION: The study results indicate that the intervention using mother's song had some significance as a nursing intervention with positive impacts. Such an intervention can help pediatric nurses improve infants' stabilization of their vital signs and behavioral states. By showing the effectiveness of such an intervention, the results of this study provide further evidence-based information in developing the practice of pediatric nursing.

We report a case of malignant histiocytosis which began with intermittent fever and scaly skin lesions. A 3-year-old girl presented with erythematous scaly papules on the face and the trunk, and high fever for 3 months. The cutaneous lesions consisted of widespread coin-sized erythematous scaly papules with marginal brownish pigmentation. She was anemic and thrombocytopenic and had impairment of the liver function. Histopathologic study of the skin lesions showed non-specfic findings except for hyperkeratosis. However, bone marrow examination revealed an increased number of histiocytes, mostly immature with active phagocytosis of erythroid cells, myeloid cells, and platelets. She was diagnosed as having malignant histiocytosis and treated with cyclophosphamide and vincristine. She died the next day after the treatment had begun.

7.Diagnosis and Clinical Features of Food Poisoning.
Journal of the Korean Medical Association 2007;50(7):592-599
Frequent large outbreaks of food poisoning or foodborne diseases are emerging problems in Korea. As for individual cases, most of food poisoning or foodborne diseases are difficult to diagnose based solely on clinical features. On the other hand, in case of large outbreaks, clinical features such as the incubation period, presence or degree of fever and the severity of upper gastrointestinal tract symptoms could be useful for the differential diagnosis. In this review, we suggest key clinical characteristics and standard laboratory diagnostic methods of epidemiologically important food poisoning or foodborne diseases.

Epithelioid smooth muscle tumor is relatively rare and potentially malignant, especially in retroperitoneum. Distinct criteria for malignancy still have not been clarified in this epithelioid variant arising in retroperitoneum. We report a deceptively benign-appearing epithelioid leiomyosarcoma in a 50-year-old female. She was admitted with abdominal discomfort and dysuria. Abdominal CT showed a well-demarcated, 10 10 cm sized, solid mass in retroperitoneum. Concomitant metastatic lesions were noted in right lung field. Surgical excision of retroperitoneal mass and right lung lobectomy were performed. The retroperitoneal mass showed yellowish-tan, well-delineated and lobulated appearance. Histologically, this tumor was composed of predominantly epithelioid, round to oval cells with distinct clear cytoplasm and slightly atypical nuclei. Mitosis was rare (0~1/50 HPF). Lung lesions were morphologically similar to that of retroperitoneum.
