By takung advantage of atomuc force mucroscopes'( AFM) capabuluty of manupulatung and processung materuals on the mucroscale, we duscovered and unvestugated a top-down preparatuon method of buologucal macromolecular nano-fubrul arrays. 50μg/mL solutuon of rat taul type I collagen monomers was used to coat the muca surface to form a proteun membrane. In the AFM Contact Mode, the AFM tup then manupulated the membrane wuth appropruate force between 100 nN and 1 mN, thus producung patterned collagen nano-fubrul arrays wuth specufuc oruentatuons. The nano-fubruls are averagely 2-5 nm un heught and 150-350 nm un wudth. Based on the relatuonshup between the structure of such nano-fubrul arrays and the AFM scannung patterns, we unvestugated and duscussed the formatuon of the proteun fubrul arrays, and verufued the molecular broom mechanusm of the AFM tup. Thus preparatuon method could potentually provude an effucuent technuque to manufacture cell culture vessels, produce buologucal probes wuth hugh specufucutues, and synthesuze novel mucro/nano materuals as well.

PURPOSE:Neopterin is a marker of activation of the T-lymphocyte/monocyte axis. We measured serum neopterin concentration to investigate whether serum neopterin levels are increased in children with Graves' disease and whether serum neopterin measurement can be used as a marker of disease activity in Graves disease. METHODS:Twenty children with Graves' disease(3 boys and 17 girls) and 15 healthy children(7 boys and 8 girls) are enrolled in this study. Serum neopterin concentrations are measured by radioimmunoassay. RESULTS:Neopterin concentration in children with Graves' disease(1.59+/-1.25ng/ml) is not higher than that of healthy children(1.51+/-0.73ng/ml). Neopterin concentration is not influenced by thyroid function and remission state. CONCLUSION: Serum neopterin level in children with Graves' disease can not be used as a marker of activity.

OBJECTIVETo observe the improvement of thyroid function and changes of Akt, p-Akt, mammalian target of rapamycin (mTOR), and para-mTOR (p-mTOR) expression in Graves' disease (GD) mice after intervened by Jiakangning Capsule (JC), and to explore possible mechanism for JC in treating GD.
METHODSGD model was established by immunizing female BALB/c mice with thyroid stimulating hormone receptor A subunit (Ad-TSHRα-289). Totally 70 successfully modeled mice were divided into the model group (n =20), the JC intervened group (n =25), the Methimazole Tablet intervened group (n =25) according to random digit table. A normal control group (n =15) and a vehicle control group (n =20, injected with Ad-null) were also set up. Mice in the JC intervened group were administered with JC suspension at the daily dose of 1. 5 g/kg by gastrogavag. Mice in the Methimazole intervened group were administered with Methimazole suspension at the daily dose of 2. 5 g/kg by gastrogavage. Equal volume of normal saline was administered to mice in the rest 3 groups by gastrogavage. All intervention lasted for 5 weeks. Six mice were selected from each group to observe pathological changes of thyroid tissues. Serum levels of thyroxine (T4), triiodothyronine (T3), thyroid stimulating hormone (TSH), and thyrotropin receptor antibody (TRAb) were analyzed by radioimmunoassay. Expression levels of Akt, p-Akt, mTOR, and p-mTOR in thyroid tissues were etermined by Western blot.
RESULTS(1) The thyroid gland in the GD model group showed proliferative changes, with enlarged follicles of various sizes. Interstitial stroma was filled with blood vessels. Structures of thyroid tissues in the JC intervened group and the Methimazole intervened group were significantly restored, and follicular hyperplasia was relieved. (2) Compared with the normal control group and the vehicle control group, levels of TRAb, T4, and T3 increased; ratios of P-Akt/β-actin, p-Akt/Akt, p-mTOR/β-actin, and p-mTOR/mTOR also increased in the model group (all P <0. 01). Compared with the model group, levels of TRAb, T4, and T3 decreased in the JC intervened group and the Methimazole intervened group (P <0. 01); ratios of p-mTOR/β-actin and pmTOR/mTOR decreased in the JC intervened group (P <0.01); ratios of P-Akt/β-actin, p-Akt/Akt, p-mTOR/β-actin, and p-mTOR/mTOR decreased in the Methimazole intervened group (P <0. 05, P <0. 01). Conclusion JC could reduce thyroid hormonc levels of GD mice and lower expression levels of mTOR, and its mechanism for improving thyroid function of GD mice might be associated with this influence.

We have recently managed a patient, 31-year-old male, who has been in the state of inferior paraparesis due to cervical disc herniation. The centrally herniated disc material was removed through the posterior approach to the lesion under the general anesthesia in left lateral position. Two days after the operation with removal of herniated disc at C5-6interspace, the subject developed quadriparesis and difficulty in urination in which the weakness of upper extremities were more severe that of the lower extremities. The signs developed postoperatively were very much compatible with those of central cord syndrome, There was improving after the removal of the hematoma and of additional herniated material at second operation which was forced to be done due to development of central cord syndrome in severe degree following the primary surgery. Recovery from neurological dysfunction in order of good and better improvement was of leg, arm, voiding and finger.

BACKGROUND: Malignant skin cancers in Korea have been increasing as in other countries, but the previous epidemiological studies have been only attempted by a single hospital unit in a limited period of time. OBJECTIVE: This study aimed to investigate and compare the frequencies, age, sex distribution, and anatomical location of the frequent skin cancers collected from several hospitals over a 10 year period between 1984-5 and 1994-5. METHODS: 258 cases of skin cancer from 4 different places in Seoul were collected for the study. Histopathological records from pathology departments and medical records were reviewed to obtain information about the frequencies. RESULTS: Overall there were 141 cases of squamous cell carcinoma (SCC)1 basal cell carcinoma (BCC), and malignant melanoma (MM) in the mid-eighties and 117 in the mid-nineties. SCC was the most common skin cancer in both periods but the frequencies and the SCC/BCC ratio dropped at the later period. The ratio of males to females was getting smaller at 1.4:1 in the mid-eighties and 1.1:1 in the mid-nineties. BCC was concentrated on the face and SCC was rather evenly distributed over the body surface. The predilection site of malignant melanoma (MM) was quite different between the two periods. The lower extremities was the main site in the mid-nineties and the head and neck in the mid-eighties. CONCLUSION: Although there was no statistical significance, the BCC/SCC ratio was increased and the male/female ratio decreased at the later period.

PURPOSE: High-risk types of human papillomavirus (HPV) are a critical etiologic factor behind cervical cancer. Adolescents are a vulnerable group for HPV infection. However, the literature on adolescent women for HPV infection and cervical cancer is limited. This study was to investigate HPV-related knowledge and perceived risk of HPV infection and cervical cancer among Taiwanese adolescent women in order to assess intervention strategies for prevention of cervical cancer and maintenance of reproductive health. METHODS: A descriptive cross-sectional study design was implemented. There were 610 adolescent women from three colleges in Southern Taiwan who participated in this study. Data were collected using an anonymous self-administered questionnaire survey. RESULTS: The results showed that the percentage of appropriate answers to HPV-related knowledge questions was only 36.8%, and smoking as the leading cause of cervical cancer received the lowest mean score for appropriate answers among the HPV-related knowledge items. The perceived risk of HPV infection and cervical cancer were moderate, with relatively lower susceptibility to infection with HPV than to cervical cancer (P < .001). Only 11.5% of the participants reported that they had received information about HPV vaccination from healthcare professionals. CONCLUSIONS: Participants lacked a comprehensive understanding of cervical cancer prevention and were not aware of their susceptibility to HPV infection. Adolescent women rarely obtained HPV-related information from healthcare professionals. Appropriate education strategies should be developed and conducted by healthcare professionals to reduce the risk of cervical cancer threat from adolescence.

Ehlers-Danlos Syndrome(EDS) is an inherited disorder of the connective tissue disease that is usually transmitted as autosomal dominant trait. The defect in the biogenesis of collagen results in varying degree of skin hyperextensibility, joint hypermobility, skin fragility and bruising. There have been several reports of cardiac or great vessel abnormalities in patients with the EDS. A 45-year-old Woman was admitted to Maryknoll hospital because of orthopnea, palpitation and epigastric discomfort. Physical examination reveals multiple variable sized bruises and increased hyperelasticity on skin, and hypermobile joint in knee and proximal interphalanges of both hands. Mitral valvular prolapse and atrial septal defect were detected by echocardiography. We report a case of EDS accompanied by mitral valvular prolapse and ostium secundum atral septal defect with brief review of literature.

Purpose:
Stroke survivors and their informal family caregivers may share the impact of the disease, which may affect family functioning and quality of life (QoL) for both. This study compared the perceptions of stroke survivors and informal family caregivers regarding family functioning and QoL and examined the QoL of those reporting effective versus ineffective family functioning.
Methods:
A cross-sectional study design and convenience sampling were used. Stroke survivoreinformal family caregiver dyads were recruited from a medical university hospital. We assessed participants’ demographic and clinical variables, including disease severity, family functioning, and QoL. Independent t-test, paired t-test, Wilcoxon signed-rank test, and ManneWhitney U test were used to analyze the data.
Results:
Seventy-one stroke survivoreinformal family caregiver dyads participated in the current study. Most stroke survivors and informal family caregivers reported effective family functioning, with no significant differences. However, significant differences existed in the seven domains (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, and role-emotional) of QoL, except emotional health. Stroke survivors reporting ineffective family functioning had a significantly lower mental component summary score, unlike informal family caregivers.
Conclusions
Our findings suggest that family functioning is crucial to ensure stroke survivors’ QoL, particularly regarding their mental health. Health professionals should prioritize mental health assessments and provide appropriate care interventions for stroke survivors in the first 1e6 months after stroke onset.

It is well known that the incidence of anterior uveitis is about 20-40% in HLA B-27 associated joint diseases, and especially common in male between the ages of 20 and 40. However, there is no study of the epidermiology and clinical features of it in Korea. The authors studied to know the incidence and clinical feature of uveitis in HLA B-27 associated joint diseases in Korea. We reviewed the records of 543 patients with HLA B-27 associated joint diseases, visited our rheumatoid center from March 1991 to August 1996. All patients were subjected to routine laboratory examinations; i.e., blood cell count, erythrocyte sedimentations rate, C reactive protein, rheumatoid factor, anti-nuclear antibody, and x-ray of the lumbosacral spine & sacro-iliac joints. 462 patientsout of 543 patients with HLA B-27 associated joint diseases had spondyloarthropathy. Anterior uveitis occurred in 32 patients (6.9%) among these 462 spondyloarthropathy patients. Clinical characteristics of the uveitis were male predominant (23/32) anterior uveitis (32/32), and unilateral (31/32).
