Background: To evaluate the rate of pathologic high-risk factors, intermediate-risk factors, and treatment outcomes in early-stage cervical cancer patients undergoing radical hysterectomy and pelvic lymphadenectomy (RHPL). Materials and Methods: Medical records of stage IA-IIA1 cervical cancer patients who underwent RHPL during the 2006 to 2012 time period and patient follow-up data until December 2013 were reviewed. Results: Of 331 patients, 52 women (15.7%) had pathologic high-risk factors and 59 women (17.8%) had intermediate-risk factors without high-risk factors. All studied patients had an initial complete response. At median follow-up time of 40.9 months (range 1-103.3 months) and mean follow-up time of$ 43.3{\pm}25.3$ months, 37 women had disease recurrence and 4 women had died of disease. The most common site of recurrence was the pelvis (64.8%). Five-year and 10-year disease free survival rates were 96.1% and 91.5%, respectively. Five-year and 10-year overall survival rates were 100% and 99.4%, respectively. Independent factors related to recurrence were pelvic node metastasis (odds ratio [OR], 2.670; 95%CI, 1.001-7.119), and >1/3 cervical stromal invasion (OR, 3.763; 95%CI, 1.483-9.549). Conclusions: The rates of pathologic high-risk and intermediate-risk factors should be considered and disclosed when counseling patients regarding primary treatment by RHPL. Oncologic outcomes of primary surgical treatment for early-stage cervical carcinoma were found to be excellent.

Purine metabolism is known factor for nuclear maturation of oocytes through both follicle cells and oocyte itself. However, it is largely unknown the roles of purine metabolism in the oocyte competence for fertilization and early development. In this study, the effects of adenosine in oocyte competence for development were examined using adenosine and its synthetic inhibitors. Adenosine treatment from GV intact stage for 18 hr (fGV) caused of decrease the fertilization rate but of increase the cleavage rate compared from the other stage treatment groups. Hadacidin did not effect on fertilization rate but increased cleavage rate without stage specificity. Adenosine did not block the effects of hadacidin with the exception of fGV group. Inhibition of purine synthetic pathways the fertilization rate was decreased in the fGV and fGVB groups but increased in the fMII group. Exogenous adenosine caused of decrease fertilization rate in the fGVB group but increase in the fMII group. Cleavage rate was dramatically increased in the adenosine treatment with synthetic inhibitors. It means that the metabolism of purine has stage specific effects on fertilization and cleavage. Exogenous adenosine had only can improve oocyte developmental competence when it treated at GV intact stage. On the other hand, endogenous synthesis in all maturation stage cause of increase the cleavage rate without effects on fertilization. These data suggest that adenosine at GV stage as a paracrine fashion and inhibitions of endogenous adenosine in all stage improve oocyte developmental competence.

Development of shoot and root, leaf water potential and photosynthetic rate affected by water stress in early growing stage of tobacco were surveyed to interpret stress response in terms of plant physiological and agricultural aspects. The growth of shoot and root was highly suppressed by water stress and the difference in dry weight by rewatering was smaller in root than in shoot. The total root length was highly decreased by water stress and the lengths of root for water stress and non-stress were 74m and 84m, respectively, after rewatering. The root growth treated by water stress was increased between 2nd and 3rd day after treatment indicating that temporary water stress at early growing stage might have increased of root zone activity for early growth stage. The leaf water potentials were decreased to -7.63MPa, -9.47MPa, -11.89MPa, -13MPa at the 2nd, 3rd, 4th and 5th day by water stress. The relative water contents were 75%, 62% and 57% at the 3rd, 4th and 5th day after treatment. Photosynthesis was reduced largely by water stress. The photosynthetic rate after treatment at 2nd day and 3rd day was dropped to 18.15$\mu$mol. $CO_2$/$m^2$ㆍsec$^{-1}$ and 9.35$\mu$mol. $CO_2$/$m^2$ㆍsec$^{-1}$. It was never recovered to the normal, even after rewatering. Stomatal conductance had been reduced since 2nd day after treatment and increased after rewatering.

Objectives: This study investigated significant factors that influence functional evaluation of stroke so as to be a fundamental data for estimating prognosis of stroke patients. Methods: 204 patients were studied within 7 days of admission, after the diagnosis of stroke through brain CT scan, brain MRI scan and clinical observations. They were hospitalized in the oriental medical hospital of Dongeui University from February to July in 2001. They were examined at the early stage of onset, after 2 weeks, 4 weeks and 6 weeks, and measured for average mark and the degree of improvement by using the Activity Index. Results: Ischemic stroke, past history of stroke, hypertension, diabetes mellitus, risk factor of obesity, non-professional emergency treatment and hospitalizing time after 1 day from onset, high blood pressure, tachycardia pulse and high blood sugar in abnormal vital sign in acute stage, conscious, cognitive or communication disorder, motor aphasia, dysphagia, constipation for more than 3 days, urinary incontinence, visual field defect, insomnia, and chest discomfort in early stage of onset had a negative influence on functional evaluation. Conclusions: Type of stroke, past history, risk factors, emergency treatment and hospitalizing time after onset, abnormal vital sign and intercurrent symptoms in Acute stage were relevant factors in predicting functional evaluation of stroke.

Background: Cholangiocarcinoma (CCA) is a very common cancer in Northeastern Thailand. Most CCA patients see a physician at a late stage when curative surgery is not possible. After diagnosis, they generally are treated by partial surgery/percutaneous drainage, chemotherapy and supportive treatment. Objective: This study aimed to assess the survival rates of CCA patients after supportive treatment. Methods: A retrospective cohort design was applied in this study. Data for 746 CCA patients were extracted from the hospital-based cancer registry of Srinagarind Hospital, Khon Kaen University. The patients were diagnosed (at least by ultrasonography) between 1 January, 2009 and 31 December, 2009 and then followed up for current status until 30 June, 2011. The cumulative survival rate was calculated by the Kaplan-Meier method, and independent prognostic factors were investigated using Cox regression. Results: The total follow-up time was 5,878 person-months, and the total number of deaths was 637. The mortality rate was therefore 10.8 per 100 person-year (95%CI : 10.1-11.7). The cumulative 3, 6, 9, 12 and 24 month survival rates were 59%, 39%, 31%, 24% and 14%, respectively. The median survival time after supportive treatment was 4 months. After adjusting for gender, age, stage, distant metastasis, histological grading and treatment, stage was a significant predictor of survival of CCA patients. Those in stage III and stage IV had a 6.78 fold higher mortality than the stage I and stage II cases (95% CI : 1.6-28.7). Conclusion: It is very important to encourage patients to see health personnel at an early stage.

Purpose: Early hypopharyngeal squamous cell carcinoma (HPSCC) is a rarely diagnosed disease, for which the optimal treatment has not been defined yet. We assessed patterns of failure and outcomes in early HPSCC treated with various therapeutic approaches to identify its optimal treatment. Materials and Methods: Thirty-six patients with stage I (n = 10) and II (n = 26) treated between January 1992 and March 2014 were reviewed. Patients received definitive radiotherapy (RT) (R group, n = 10), surgery only (S group, n = 19), or postoperative RT (PORT group, n = 7). All patients in both the R and PORT groups received elective bilateral neck irradiation. In the S group, 7 patients had ipsilateral and 8 had bilateral dissection, while 4 patients had no elective dissection. Results: At a median follow-up of 48 months, the 5-year locoregional control (LRC) rate was 65%. Six patients had local failure, 1 regional failure (RF), 3 combined locoregional failures, and 2 distant failures. There was no difference in 5-year LRC among the R, S, and PORT groups (p = 0.17). The presence with a pyriform sinus apex extension was a prognosticator related to LRC (p = 0.01) in the multivariate analysis. Patients with a bilaterally treated neck showed a trend toward a lower RF rate (p = 0.08). Conclusion: This study shows that patients with early stage HPSCC involving the pyriform sinus apex might need a tailored approach to improve LRC. Additionally, our study confirms elective neck treatment might have an efficacious role in regional control.

We investigated whether endothelium-derived NO and endothelin-1 might result enhanced vasoconstriction induced by administration of norepinephrien (NE) at the early stage of one-kidney, one-clip (1K1C) renal hypertensive rats. We also studied the relation ship of renin-angiotensin system (RAS) using rat aorta in this hypothesis. L-NMMA (30$\mu$M) and L-NAME(30${\mu}M$) enhanced vasoconstriction induced by NE in thoracic aorta of control rats. However angiotensin converting enzyme (ACE) inhibitor didn't. The aorta of 1KIC rats showed a singnificantly exaggerated contractile response to NE as compared with control rats. Rub-bing the endothelium abolished this difference. Ach and SNP-induced vasorelaxation show no significant difference between 1KIC and control rats. The treatment of phosphoramidon (10${\mu}M$) and oral administration of captopril (0.05, w/v%) abolished the exaggerated contractile response to NE at early stage of 1KIC rats. These results suggest that the increase of contractile response at the early phase in 1KIC rat is partially involved in the activation of ACE.

With the widespread use of the obstetrical ultrasound, identification of a fetal suprarenal mass becomes more common. Most of these masses prove to be congenital neuroblastomas (CNB) postnatally. However, the diagnosis is often confused with other benign lesions and the post-natal management remains controversial. The medical records of 13 patients that underwent primary surgical excision for an antenatally detected adrenal CNB, between January 1995 and April 2009, were reviewed retrospectively. The clinical, radiological, surgical, and pathological data on the suprarenal mass were collected. Staging evaluation was performed after histological confirmation of the CNB. Most of the CNBs were stage I (N=11), with 1 stage IV and 1 stage IV-S. Four patients (3 stage I and 1 stage IV-S) had N-myc gene amplification. The stage I patients were cured by surgery alone, and stage IV patients underwent 9 cycles of adjuvant chemotherapy and currently have no evidence of disease after 39 months of follow-up. The patient with stage IV-S is currently receiving chemotherapy. There were no post-operative complications. For early diagnosis and treatment, surgical excision should be considered as the primary therapy for an adrenal CNB detected before birth. The surgery can be safely performed during the neonatal period and provides a cure in most cases. Surgical diagnosis and treatment of CNB is recommended in neonatal period.

Thymic tumors are the most common tumors in the anterior mediastinum. Total resection is the main treatment and predictor of longer survival. Adjuvant radiotherapy alone or in combination with chemotherapy is recommended with incomplete excision or advanced disease. Thirty seven patients with thymic tumors were included in this retrospective study from January 2001 till December 2012. They were studied regarding age, sex, performance status, tumor size and invasion, stage, pathology, treatment given, overall and progression free survival. Myasthenia gravis was present in 18.1% of the patients. Masaoka stage III was diagnosed in 40.5% of the cases followed by stage II in 24.3% and the other stages with lower percentages. Pathology type B3 was the most frequent followed by B2 and B1 with percentages of 27, 24.3 and 21.7 respectively. Complete resection was conducted in 11 cases (29.75%). Partial resection or debulking was done in 15 (40.5%) and a biopsy was taken in 11 cases (29.8%) Adjuvant chemotherapy was given to 14 patients (37.8%) and neoadjuvant to 13 (35.2%). Adjuvant radiotherapy was given to 17 patients (46%) and neoadjuvant to 14 (37.8%). The 5-year overall survival by was 83% for stage I, 71% for stage II, 60% for stage III, and 44% for stage IV (p=0.0426). Five year progression free survival was 71% for stage I, 62% stage II, 42% stage III, and 37% for stage IV (p=0.0532). In conclusion with the rare thymic tumors early stage and complete resection have the highest impact on overall and progression free survival.
