Chinese Journal of Endemiology 2012;31(5):556-558
Objective In order to understand the Sanya of iodine deficiency disorders(IDD) prevention and cure,and to provide a scientific basis for formulating corresponding control measures.Methods According to the requirements of Iodine Deficiency Disorders Monitoring Program,one townships(districts) in Sanya of Hainan in 2011 were selected based on their positions of east,south,west,north and center,respectively.Four administrative villages in each township(district) were selected in the same way.Fifteen salt samples,8 urine samples of women of childbearing age and 1 drinking water sample from each adninistrative village were collected.In the primary school of each township(district),40 students aged 8 to 10 were selected to check up their thyroid,test their intelligence quotient (IQ) and urinary iodine.Thirty three fifth-grade students in each of the primary schools were selected to launch a questionnaire survey of health education knowledge and test(semiquantitative test) their household edible salt.Salt iodine was detected by direct titrimetry; urinary iodine and water iodine were detected by As-Ce catalytic spectrophotometry; and children's IQ values were measured using the Combined Raven Test (CRT) in rural edition.Results Totally 300 salt samples were tested,and the median salt iodine was 31.0 mg/kg.The iodized salt coverage rate was 96.67% (290/300),and the consumption rate of qualified iodized salt was 96.00% (288/300).Totally 200 urine samples were tested,and the median urinary iodine was 194.6 μg/L;and the range of urinary iodine was between 18.50 μg/L and 655.10 μg/L,the proportions of less than 50 μg/L and between 50 μg/L and < 100 μg/L were 4.00% (8/200) and 13.50% (27/200),respectively.A total of 200 children were examined by palpation,and the goiter rate was 1.00%(2/200).Mean IQ value of the students was 97.66 and there were 8 students whose IQ values were lower than 69 and 20 students whose IQ values were between 70 and 79.The average score was 3.24 of the 165 students who took part in the questionnaire survey of health education knowledge.There were 43 students who failed in the exam,and the failed rate was 26.06%.The coverage rate of iodized salt in household was 96.36% (159/165).The median of urinary iodine of the 160 women of childbearing age was 162.95 μg/L,the range of urinary iodine were between 9.50 μg/L and 908.80 μg/L,and the proportion of less than 100 μg/L was 19.38% (31/160).The consumption rate of eligible iodized salt was 96.90% (155/160).The levels of water iodine of the 20 water samples from the 5 townships(districts) were all less than 10.0 μg/L.Conclusions Sanya is still in the area lack of iodine in the environment.In general Sanya has reached the goals of elimination of iodine deficiency disorders,but there are still some of the children and women of childbearing age who are iodine deficient.
2.Immunomodulatory features of chemotherapeutics
Journal of Medical Postgraduates 2004;0(01):-
Chemotherapeutic drugs conventionally used for their cytotoxic activity can also exert their influence on the immune system by grooming the tumor microenvironment,abrogating immune tolerance and inciting immune reconstitution.Due to their immunomodulatory features,chemotherapeutics,used as a preconditioning regimen and combined with subsequent immunotherapy,can mobilize the immune system to generate antitumor immune response.The synergy between chemotherapy and immunotherapy has brought some enlightenment to the development of new protocols for cancer treatment.
4.Advances on DNA methylation for noninvasive tumor molecular diagnosis
China Oncology 2001;0(03):-
DNA methylation is one of the most common epigenetic events in eukaryotic cell.Aberrant DNA methylation is tightly related to tumorigenesis.Recent evidence indicates that DNA methylation is a promosing biomarker for cancer.The cancer-associated DNA methylation events could be detected from serum(plasma),urine,stool and bronchoalveolar lavage,providing a new choice for noninvasive cancer diagnosis.In this review,we summarized the advances on DNA methylation for noninvasive cancer diagnosis.
5.Application of Cisatracurium in Hiatal Hernia Repair of Newborn
China Pharmacy 2005;0(23):-
OBJECTIVE: Approach to the pharmacodynamics of cisatracurium in newborn. METHODS: Sixty patients were randomized to two groups: Group Ⅰ and Group Ⅱ , received( iv) 2ED95 or 3ED95 cisatracurium in 5 seconds respectively, n=30. Neuromuscular transmission was monitored and Intubation conditions were assessed at 120s after cisatracurium administration using a 4- part scale. Observe onset time, TOF no reaction period, duration of action, recovery index, duration in vivo. RESULTS: The muscular blockage and conditions of intubation after 120s were different between two groups( P0. 05) . CONCLUSIONS: 3ED95 cisatracurium produces quicker, safer onset time and acceptable intubating conditions in the great majority of newborn than 2ED95. The TOF no reaction period, duration of action and duration in vivo were longer in 3ED95 group than in 2ED95 group, but recovery index are no significant between 2 groups with dosage.

Bacillus anthracis , the aetiological agent of anthrax, was the first discovered pathogenic bacterium in history Rapid progresses have been made on this field in recent years, especially; Bacillus anthracis has been sequenced successesfully early this year and published on the Internet The anthrax pathogenesis is always central to the study and there has been an enormous amount of work to elucidate it In this review, we will focus on the latest findings that concern three aspects of anthrax pathogenesis: Bacillus anthracis genome, pathogenic substances and pathogenesis mechanism
7.Construction of knowledge service system for university students'innovation and undertaking training program
Chinese Journal of Medical Library and Information Science 2015;24(12):38-41
Construction of knowledge service system for university students'innovation and undertaking training program was proposed by analyzing their difficulties in information access during innovation and undertaking train-ing.The key points in constructing knowledge service system were pointed out, namely establishing professional service teams, providing stereoscopic and diversified service, establishing feedback and evaluation systems, and building powerful platform for information exchange.
8.Etiologic classification of ischemic stroke
International Journal of Cerebrovascular Diseases 2011;19(7):535-538
Etiologic classification of ischemic stroke is the basis for epidemiological investigation, risk factor screening developing individualized treatment plan and prognostic measures. The etiologic classifications, such as TOAST, CCS, and ASCO, are more generally accepted methods at present. This article reviews the advantages and disadvantages from the diagnostic criteria and clinical application.
9.Endothelial monocyte-activating polypeptide- Ⅱ and tumor
Journal of International Oncology 2011;38(11):819-822
Endothelial monocyte-activating polypeptide-Ⅱ (EMAP-Ⅱ ) is a novel proinflammatory cytokine with proinflammatory,proapoptotic and antiangiogenic properties.It is associated with many tumorassociated proteins,such as tumor necrosis factor,vascular endothelial growth factor,hypoxia inducible factor-1α,arginyl-tRNA synthetase,and insulin-like growth factor- Ⅰ.EMAP-Ⅱ has anti-tumor properties and has a good prospect in cancer prevention and treatment.
