ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects and mechanisms of Curcumol beta-cyclodextrin Compound (CbetaC) on the proliferation and apoptosis of esophageal carcinoma cell line TE-1.</p><p><b>METHODS</b>The CbetaC was prepared by saturated solution and confirmed by infrared absorption spectroscopy. The effects of CbetaC (at 25, 50, 100 mg/L) on the proliferation of human esophageal carcinoma cell line TE-1 in vitro was analyzed by MTT assay. The cell cycles and apoptosis were detected by flow cytometer. The relative expression of survivin mRNA was detected by real-time fluorescent quantitative PCR and calculated by the 2(-deltaCt) method. The protein expression of survivin was measured by Western blot.</p><p><b>RESULTS</b>Compared with the control group, results of MTT showed that CbetaC at each dose significantly inhibited the proliferation of TE-1 cells in a dose-dependent manner (P < 0.05). The results of flow cytometry showed that CbetaC resulted in the cell cycle arrest at G0/G1 and G2/M phase, and promoted the cell apoptosis. Besides, when compared with the control group, the protein and mRNA expressions of survivin obviously decreased in each CbetaC group (P < 0.05).</p><p><b>CONCLUSIONS</b>CbetaC could inhibit the proliferation of esophageal carcinoma cell TE-1 and promote the apoptosis. Its inhibition on the survivin expression was correlated with its inhibition on the malignant phenotypes of esophageal carcinoma cells.</p>

ABSTRACT

BACKGROUND:Stroke is the leading cause of death and long-term disability. This study was undertaken to investigate the factors influencing daily activities of patients with cerebral infarction so as to take interventional measures earlier to improve their daily activities. METHODS:A total of 149 patients with first-episode cerebral infarction were recruited into this prospective study. They were admitted to the Encephalopathy Center, Department of Neurology, the First Affiliated Hospital of Wenzhou Medical College in Zhejiang Province from August 2008 to December 2008. The baseline characteristics of the patients and cerebral infarction risk factors on the first day of admission were recorded. White blood cell (WBC) count, plasma glucose (PG), and many others of laboratory targets were col ected in the next morning. Barthel index (BI) was calculated at 2 weeks and 3 months respectively after onset of the disease at the outpatient clinic or by telephone cal . Lung infection, urinary tract infection and atrial fibrillation if any were recorded on admission. The National Institute of Health Stroke Scale (NIHSS) scores and the GCS scores were recorded within 24 hours on and after admission, at the second week, and at the third month after the onset of cerebral infarction respectively. RESULTS:The factors of BI at 2 weeks and 3 months after onset were the initial PG level, WBC count and initial NIHSS scores. Besides, urinary tract infection on admission was also the factor for BI at 3 months. CONCLUSION:Active measures should be taken to control these factors to improve the daily activities of patients with cerebral infarction.

ABSTRACT

<p><b>OBJECTIVE</b>To study the epidemiological features of tic disorders (TD) among schoolchildren in Wenzhou area.</p><p><b>METHODS</b>Stratified cluster sampling was carried out to investigate TD in 9742 schoolchildren aged 7 to 16 years old in Wenzhou.</p><p><b>RESULTS</b>The average prevalence rate of TD among school-age children was 104/10 000 (166/10 000 for males, 29/10 000 for females). There was a significantly higher prevalence rate for males than that for females (chi(2) = 43.96, P < 0.001, prevalence ratio = 5.7, prevalence ratio 95% CI: 3.20 - 10.30). The prevalence rates of clinical subtypes in males was significantly higher than that of females while pupils was significantly higher than that in high school students (chi(2) = 11.33, P < 0.01, prevalence ratio = 2.2, prevalence ratio 95% CI: 1.37 - 3.43). Prevalence rate of transient tic disorders (TTD), chronic motor vocal tic disorder (CMVTD), tourette syndrome (TS) were 34/10 000, 27/10 000 and 43/10 000 respectively with the highest among 9-10 years old group. The mean onset age of TD was 8.5 +/- 2.8 years. The peak of onset was among 6-10 year olds. The rate of delayed diagnosis of the disorders was 69.3% and the median in delayed diagnosis was 1.0 year.</p><p><b>CONCLUSION</b>TD is a common disease with high rate of misdiagnoses among schoolchildren in Wenzhou area. Physicians and population should be trained to identify the syndromes and to practice correct diagnosis and effective treatment as early as possible.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the prevalence and distribution of Tourette syndrome (TS).</p><p><b>METHODS</b>Nine thousand, seven hundred and forty-two children and juveniles aged 7 - 16 years in Wenzhou were studied, using cluster random sampling method.</p><p><b>RESULTS</b>The prevalence of TS among school-age children was estimated to be 0.43% (0.74% for males and 0.07% for females). The prevalence of male children and juveniles was higher than that of female children and juveniles (chi(2) = 25.09, P < 0.001, prevalence ratio = 10.95, prevalence ratio 95% CI: 3.38 - 35.46). The highest prevalence of TS was between 9 - 10 years old. The mean age at onset of TS was 7.7 +/- 2.7 years, with 45.2% of them among 6 - 7 year olds. The rate of delayed diagnosis and rates of misdiagnosis and misclassification of the syndromes were 78.6%, 42.9% and 23.8%, respectively.</p><p><b>CONCLUSION</b>Tourette syndrome had been a common disease of children and juveniles in Wenzhou area. The disease was correlated with age and sex, often misdiagnosed and misclassified. Physicians and as well as general publics should be trained to identify the cases.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore etiologic fraction (EF) and interaction of serum hepatitis B surface antigen (HBsAg) carriage and other risk factors for primary hepatocellular carcinoma (PHC) in Wenzhou, Zhejiang, China.</p><p><b>METHODS</b>1:1 matched case-control study was carried out in Wenzhou, with 180 cases of PHC and 180 controls. EF and interactions of serum positive HBsAg [HBsAg(+)] and other risk factors for PHC were analyzed by Mantel-Haenszel stratified method and conditional multiple logistic regression.</p><p><b>RESULTS</b>Serum HBsAg(+), poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events all were risk factors for PHC, with EFs of 0.728, 0.245, 0.224, 0.084, and 0.234, respectively. There existed interactions of HBsAg(+) with other risk factors, including poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events, with etiologic fractions attributable to interaction [EF (A x B)] of 0.770, 0.630, 0.848, and 0.627, and indices of interaction of 0.789, 0.638, 0.852, and 0.634, respectively.</p><p><b>CONCLUSIONS</b>Main risk factor for PHC in Wenzhou, Zhejiang, China could include HBsAg(+), poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events. HBsAg(+) plus any of the following factors, such as poor economic status during the past five years, preferring intake of pickled vegetables, history of PHC in their first-degree relatives, and negative life events, could increase the risk of PHC.</p>
