DNase I footprinting assay using liver nuclear extracts revealed six protected regions between nucleotide -600 and +110 and hence named Box I-VI. Upstream promoter element (UPE), a DNA element playing crucial role in transcriptional control of the tissue specific expression of pancreatic beta-cell, has been detected within the proximal region of rat GLUT2 promoter. This region is included in Box VI. The protein-DNA interaction in this region (Box VI) was confirmed by mobility shift assay using liver nuclear extracts. Deletion of the region between -585 bp and -146 bp resulted in dramatic changes in promoter activity when they were expressed in liver and beta-cell derived cell line. When -585/-146 construct was expressed in liver, the activity was decreased to 46%, whereas the activity in beta-cell line, HIT-T15 cell, was increased by 84% when compared to -146/+190 construct. These opposing phenomena can be explained by the fact that beta-cell specifically expresses the UPE binding protein. Assuming that there may be Box VI-binding protein playing negative roles both in hepatocyte and beta-cell, and that the protein acts as a negative regulator of GLUT2 gene, the UPE binding protein in the beta-cell may overcome the inhibition by binding to the protein.

Accessory renal artery (ARA) is a kind of developmental anomaly in renal artery. It is important in respect to clinical medicine, for example primary hypertension, renovascular disease, inferior vena caval obstruction, ureteral obstruction, occurrence of other vascular anomalies such as accessory renal veins, surgical importance and renal transplantation. However, up to few research of ARA was reported in dissection of cadavers. In our dissecting theater, 12 accessory renal arteries for 10 cadavers were found during dissection the 22 cadavers from 1995 to 1996. 1. Two cases were bilateral and 8 cases were unilateral accessory renal arteries. 2. Seven cases were left and 5 cases were right accessory renal arteries. 3. Two cases originated at the abdominal aorta between celiac trunk and superior mesenteric artery, 7 cases originated between superior mesenteric artery and inferior mesenteric artery, and 3 cases originated below inferior mesenteric artery. 4. Seven cases have no branches during their courses, 4 cases have 3 branches, and a case has 2 branches. 5. Seven cases entered into renal parenchyma through renal hilum, 5 cases entered into apical and arterosuperior segments, and 6 cases entered into inferior segment.

Purpose: Tisochrysis lutea is a marine microalga known for its anticancer and antioxidant properties. This study aimed to investigate the efficacy and safety of T. lutea in adults with dry eye symptoms. Methods: One hundred participants with dry eye symptoms were enrolled and divided into two groups: one received T. lutea powder (test group), and the other received control food (placebo, control group) for 12 weeks. Subsequently, the measurements of ocular surface disease index (OSDI), tear secretion (Schirmer’s test), tear break-up time (TBUT), corneoconjunctival staining, and safety assessments were compared between the test and control groups. Results: In terms of the OSDI score, the value for the test group decreased by 6.51 points after 12 weeks of T. lutea powder intake, compared with baseline, whereas that in the control group decreased by 2.88 points, demonstrating a significant difference between the two groups (p = 0.002). The results of Schirmer's test also showed significant improvements: in the test group, the result for the right eye increased by 1.33 ± 3.71 after 12 weeks (p = 0.020), and that for the left eye increased by 1.93 ± 3.33 (p = 0.0003). However, no significant increases in the results were observed in the control group. Additionally, TBUT showed a significant increase from baseline in the right eye of the test group after 6 weeks of T. lutea powder intake (p = 0.043). Conclusions After 12 weeks of consumption in the powdered form, T. lutea improved the symptoms of dry eye and increased tear production. Therefore, T. lutea can be used as an eye supplement for adults with dry eye symptoms.

PURPOSE: We aimed to investigate the clinical characteristics and associated diseases in children with a horseshoe kidney and compared these data between children and adults. METHODS: We performed a retrospective analysis of the medical records and radiological findings of 43 patients diagnosed with a horseshoe kidney in the Busan Paik Hospital. The subjects were divided into the children's group (14 cases, age <18 years) and the adult group (29 cases, age > or =18 years). RESULTS: The study group consisted of 17 males and 26 females with a median age of 34 years. In the children's group (14 cases), 5 subjects were male and 9 were female, with a mean age of 6.7+/-6.2 years. Most of the subjects were asymptomatic and were incidentally diagnosed with horseshoe kidney during their evaluation for another disease. Among the associated diseases in the children's group, Turner syndrome was the most common (5 cases), whereas ureteropelvic junction (UPJ) stricture was observed in 2 cases (14.2%). None of the children exhibited abnormal renal function during the follow-up period. In the adult group (29 cases), 12 subjects were male and 17 were female, with a mean age of 48 years. Eighteen patients were incidentally diagnosed with horseshoe kidney during their evaluation for another disease, and 11 patients had hematuria or abdominal pain due to renal stones. Among the associated diseases in the adult group, Turner syndrome was the most common (5 cases), and UPJ stricture was observed in 5 cases; the other accompanying diseases included hydronephrosis and overactive bladder. Six patients exhibited decreased renal function (serum creatinine level >1.5) during the follow-up period. CONCLUSION: Horseshoe kidney is usually diagnosed incidentally in both children and adults. In the present study, we noted that Turner syndrome was the most common associated disease in children. In addition, most children were asymptomatic but had a high risk of urologic complications after the transition to adulthood. Therefore, children with horseshoe kidney require continuous follow-up.

BACKGROUND: we have evaluated the association of age, smoking, type of anesthesia, type of operation, duration of surgery, previous history of chronic pulmonary diseases with postoperative pulmonary complications and identified which parameter of preoperative spirometry was a predictor of postoperative pulmonary complications. METHOD: In 270 patients older than 60 years, the postoperative pulmonary complications were evaluated according to age, smoking, type of anesthesia, type of operation, duration of surgery, previous history of chronic pulmonary diseases and the parameters of preoperative spirometry were analyzed. RESULTS: The postoperative pulmonary complications rates were significant higher among patients older than 70 years, and among those with previous chronic pulmonary diseases or their smoking history. The pulmonary complications were increased among patients with general anesthesia or duration of surgery more than 2 hours. The pulmonary complications rates did not differ according to sex, type of operation. The patients with hypercarbia(PaCO2> 45mmHg) have more increased postoperative complications. The preoperative FEVl less than 1 liter, FVC, MMEFR & MVV less than 50% of predicted respectively were predictive of complications. CONCLUSION: Age 70, history of smoking,duration of operation more than 2 hours, general anesthesia, previous chronic pulmonary disease and hypercarbia (> or=45mmHg) on preoperative arterial blood gas analysis were predictivd of pulmonary complications. Among the parameters of spirometry, FEV1, FVC, MMEFR and MVV were indicator of predicting postoperative pulmonary complications.

PURPOSE: This study examined breast cancer screening practice and health promoting behaviors and the predicting factors of breast cancer screening practice in Chinese women. METHODS: A correlational research design was used to recruit a convenience sample of 770 women living in four cities (Beijing, Shanghai, Guangzhou, and Xi'an) in China. Participants completed self-report questionnaire consisting of general characteristics, breast cancer screening, health promoting behaviors, perceived benefits and perceived barriers. RESULTS: The participants were mostly 36-55 years old (51.3%), married (86.8%), premenopause (77.7%), had children (83.4%), and breastfed (73%). About 60% of Chinese women participated in some type of breast cancer screening practices, among them only 60 (7.8%) women used mammography, ultrasonogram and breast self-examination. The main reason for doing breast cancer screening was "feeling necessary for the screening". About 36% of the participants reported they did not perform any of screening practices, because they "don't feel it necessary". The women who had breast cancer screening regularly reported better health promoting behavior and perceived benefits and less perceived barriers than those who did not (F = 10.45, p < .001). Logistic regression showed that model 1 (age, higher education, being employed) and model 2 (perceived benefits and health behaviors) were the significant predicting factors (p < .05), explaining 10-13.8% of variance in breast cancer screening practice. CONCLUSION: On the basis of these results, public education about importance of breast cancer screening and health promoting behavior should be strongly advocated by health professionals and mass media in China.

Abnormal attachment of the placenta (Placenta accreta, increta, and percreta) is an uncommon but potentially lethal cause of maternal mortality from massive postpartum hemorrhage. A 33-yr-old woman, who had been diagnosed with a placenta previa, was referred at 30 weeks gestation. On ultrasound, a complete type of placenta previa and multiple intraplacental lacunae, suggestive of placenta accreta, were noted. For further evaluation of the placenta, pelvis MRI was performed and revealed findings suspicious of a placenta increta. An elective cesarean delivery and subsequent hysterectomy were planned for the patient at 38 weeks gestation. On the day of delivery, endovascular catheters for balloon occlusion were placed within the hypogastric arteries, prior to the cesarean section. In the operating room, immediately after the delivery of the baby, bilateral hypogastric arteries were occluded by inflation of the balloons in the catheters previously placed within. With the placenta retained within the uterus, a total hysterectomy was performed in the usual fashion. The occluding balloons were deflated after closure of the vaginal cuff with hemostasis. The patient had stable vital signs and normal laboratory findings during the recovery period; she was discharged six days after delivery without complications. The final pathology confirmed a placenta increta.

BALT(bronchial associated lymphoid tissue) lymphomas are a distinct subgroup of low-grade B-cell extranodal non-Hodgkin's lymphoma, which are classified as a marginal-zone lymphomas. The majority of the patients are asymptomatic or their pulmonary lesions is often discovered incidentally on a routine chest radiograph. A 50-year-old man was admitted for an the evaluation of cough, dyspnea and fever. His chest CT showed ground glass appearance with interlobular septal thickening in both lower lobes, right middle lobe and left lingular division. He had been initially diagnosed with lipoid pneumonia and was kept under observation. However, his chest lesion showed continuous progression and a video-associated thoracoscopy was performed His pulmonary lesion was confirmed histologically to be a BALT(bronchial associated lymphoid tissue) lymphoma. We report a case of a BALT lymphoma, which was initially misdiagnosed as lipoid pneumonia.
