BACKGROUND AND PURPOSE: The catastrophic Chi-Chi earthquake of September 21, 1999 in Taiwan provided a unique opportunity to study the disaster's psychiatric impact on survivors. This study assessed the development of psychiatric disorders among residents in a Taiwanese village near the epicenter of the earthquake within 6 months of the disaster. METHODS: A total of 442 of the 602 actual living residents of Tong-Chi village who were over 16 years of age and were present in the community at the time of the earthquake were included in this population survey. Subjects were interviewed by psychiatrists using the Mini-International Neuropsychiatric Interview and questionnaires to collect demographic information and risk factors for psychiatric disorders 4 to 6 months after the earthquake. RESULTS: The prevalence rates were 9.5% for current major depression, 2.8% for past major depressive episode, and 7.9% for post-traumatic stress disorder (PTSD). Females had significantly higher rates of most psychiatric disorders. After controlling for covariates, the significant risk factors for PTSD were female gender and having sought medical service after the earthquake. Significant risk factors for major depressive episode were divorced/widowed status, education level equal to or below primary school, and prominent house damage. CONCLUSION: This population survey of earthquake disaster survivors found an increased prevalence of psychiatric disorders after exposure to a catastrophic earthquake. These results highlight the need for prompt therapeutic attention to residents of earthquake disaster areas after the event. 相似文献
AIMS: To develop an alternative assay for specific genotyping of the -alpha(4.2) thalassaemia deletion based on the DNA sequence features surrounding the breakpoint. METHODS: The 5' and 3' ends of the breakpoint regions of the -alpha(4.2) allele and the normal homologous segments were sequenced in Chinese individuals. A sequence haplotype composed of four single nucleotide variations within the X2/X1 box of the -alpha(4.2) breakpoint region was found in all of the 10 Chinese -alpha(4.2) thalassaemia alleles studied. Based on these findings, a novel polymerase chain reaction (PCR)/denaturing high performance liquid chromatography (DHPLC) assay was developed for rapid genotyping of the -alpha(4.2) allele instead of traditional Southern blotting or Gap-PCR. This method involves amplification of the alpha globin target sequence encompassing these four polymorphic sites, followed by a partially denaturing HPLC analysis using the transgenomic WAVE DNA fragment analysis system. RESULTS: The three major genotypes (-alpha4.2/alphaalpha, -alpha(4.2)/--SEA, and alphaalpha/alphaalpha) could be distinguished through the characteristic chromatograms generated by the WAVE system. The accuracy of this technique was evaluated blindly, and the results were 100% (40 of 40) concordant with the genotypes previously characterised by Southern blotting or Gap-PCR. CONCLUSIONS: This study validates the PCR/DHPLC approach as a simple, rapid, highly accurate, and cost effective method, potentially adaptable for use in epidemiological surveys, genetic screening, and diagnosis of silent alpha+ thalassaemia and Hb H disease. 相似文献
This purpose of this study was to investigate the relationship between quality of life and psychiatric impairment in a Taiwanese community located near the epicenter of the 1999 earthquake, as assessed four to six months after the natural catastrophe. Trained assistants interviewed the 4223 respondents using the disaster-related psychological screening test (DRPST), an instrument specifically designed and validated by senior psychiatrists for assessment of psychiatric impairment after natural catastrophe. Additionally, the 36-Item Short-Form Health Survey (SF-36) was used to evaluate quality of life. The collected results were analyzed using Windows SPSS 10.0 software. Psychiatric impairment rated moderate to severe was assessed for 1448 (34.3%) of the responding residents. The 4223 respondents were divided into 4 psychiatric-impairment groups based on DPRST score: healthy (n = 952); mild impairment (n = 1823); moderate impairment (n = 1126); and, severe impairment (n = 322). The four groups were compared for a number of salient factors, including gender, age, current marital status and psychiatric-impairment score, to determine impact on quality of life. Respondents assessed as psychiatrically impaired tended to be older, female, divorced/widowed, and less educated, and they were more likely to have experienced major familial financial loss as an immediate consequence of the earthquake. Further, the greater the severity of the psychiatric impairment, the lower the scores for quality of life, for both the physical and mental aspects of this important general indicator. 相似文献
Objective: To investigate the mRNA and protein expression of FK506-binding protein 52 (FKBP52) in the chorionic villi of patients with recurrent spontaneous abortion (RSA) and normal women during early pregnancy.
Methods: Fresh chorionic villus tissues were collected from 60 subjects. A total of 30 patients with a history of RSA were enrolled into the RSA group and 30 normal pregnant women were enrolled into the control group. The FKBP52 mRNA expression levels in chorionic villi of the RSA patients and healthy controls were measured via semiquantitative RT-PCR. The protein distribution and expression levels of FKBP52 in chorionic villi were analyzed through immunohistochemistry (IHC). The correlation between FKBP52 expression and RSA was analyzed.
Results: We demonstrated that FKBP52 mRNA is expressed in chorionic villi samples of normal pregnancy and RSA. RSA patients exhibited significantly lower FKBP52 gene expression levels compared with those in normal pregnancies (p?<?0.05). FKBP52 immunoreactivity in chorionic villi was mainly observed in trophoblast cell cytoplasm. The FKBP52 protein expression levels in the chorionic villi of RSA patients was significantly lower than in normal women during pregnancy (p?<?0.05).
Conclusions: FKBP52 protein levels were decreased in the chorionic villi of RSA patients, which indicate that the decrease in FKBP52 may be associated with RSA. The low FKBP52 mRNA expression level, which is consistent with the IHC result, may affect embryonic development and even lead to abortion. FKBP52 may be involved in the pathogenesis of RSA and new therapies that increase the FKBP52 expression may help treat RSA. 相似文献
Seven compounds have been isolated from the whole plant of Strobilanthes cusia (Nees) O. Ktze. Three of them are triterpenes (Ⅰ~Ⅲ), two are indole alkaloids (Ⅳ, Ⅴ), two are quinazolinone alkaloids (Ⅵ, Ⅶ). On the basis of spectral analysis and physicochemical properties, their structures were established as lupeol (Ⅰ), betulin (Ⅱ), lupenone (Ⅲ), indigo (Ⅳ), indirubin (Ⅴ), 4 (3H)-quinazolinone (Ⅵ), 2, 4 (1H, 3H)-quinazolinedione (Ⅶ). Ⅵ and Ⅶ were found from natural plant for the first time.The results of the pharmacological tests demonstrate that compound Ⅴ has anticancer activity and compound Ⅵ has hypotensive action. Compound Ⅶ can be quantitatively determined by HPLC, which may serve as a quality control standard for materia medica and its preparations. Compounds Ⅵ and Ⅶ have been confirmed by means of synthesis. 相似文献
