1. Effect of Fukushima nuclear plant accident on human health and the medical protection
Academic Journal of Second Military Medical University 2011;32(4):349-353
The hazards Fukushima nuclear plant accident causes to human beings might be the second only to Chernobyl nuclear plant accident in the former Soviet Union. The accident has deleterious health effects on Japanese rescue workers, nearby residents and other contaminated subjects, and there are not only short-term irradiation injuries, but also long-term biological effects, with the long-term biological effects caused by low-dose irradiation being the leading one. The radioactive dusts falling to our country is far from enough to cause damage to human health. The main protective measures include shielding with buildings, clothing, and masks, cleaning/removing the radioactive contamination timely, and taking protective drugs. While developing our nuclear power cautiously and scientifically, we should also enhance the corresponding research on medical rescue and protection in case of nuclear accidents. We should also reinforce our emergency response system, training of personnel, technique and equipment, and special protective measures, so as to minimize the damages in case of any nuclear accidents and effectively protect the physical and psychological health of the people. In this paper, we discusse the possible health influence and medical protection of Fukushima nuclear plant accident, the proper attitude towards development of nuclear power, and strengthening of security measures and related scientific research.

Objective To understand the iodine deficiency disorders in Xunhua county Qinghai province, and to provide reference values for setting up prevention and control strategy. Methods According to historical data of Xunhua county, 1 township center elementary school and 1 village elementary school were sampled in Qingshui, Baizhuang, Hongqi, Jiezi and Galeng townships. A total of 9 elementary schools were investigated (Caleng has only 1 elementary school). Fourty children aged 8-10 years were checked thyroid size by palpation in every school. Twenty children were chosen to assay their urinary iodine and edible salt iodine in every school. Thirty 5-grade students were surveyed by questionnaire on health education in every school. Ten housewives were inquired prevention knowledge on iodine deficiency disorders and salt iodine level was tested in every village. Results Goiter rate was 7.9%(30/378) in children aged 8-10 years, with Baizhuang and Galeng the highest (11.9%,5/42), and Qingshui the lowest (2.4%, 1/42). The median was 196.5 μg/L in children aged 8-10 years, and urinary iodine level lower than 50 μg/L was accounted for 5.3% (11/208), but that value was 25.0% (5/20)in Galeng. The average qualified rate of using edible salt was 91.4%(159/174), and that rates were 79.0%(15/19), 83.3%(15/18) and 89.5%(17/19) in Chajia, Tuanjie and Minzhu villages, respectively. The average score were 2.8, 2.1 in health education survey of the 5-grade students and housewives. Conclusions After years effort in prevention and control of iodine deficiency disorders, remarkable progress has been made in Xunhua County. The monitoring of iodized salt and the knowledge spreading are still need to be strengthened.

Objective To investigate the diagnostic and therapeutic characteristics of prostate cancer with prostate specific antigen(PSA)4-10?g/L. Methods The data of prostate biopsies for the patients with PSA 4-10?g/L from May 1998 to February 2004 and the treatment and prognosis of these patients were retrospectively analyzed. Results In the 141 cases, 34 were diagnosed as prostate cancer, including 3 cT1, 21 cT2, 6 cT3 and 4 cT4. Mean Gleason score was 5.8, and the mean Gleason scores of cT1 and cT2 were significantly lower than those of cT3 and cT4. Twenty-four cases of cT1 and cT2 underwent radical prostatectomy. Four cases of cT3 recieved radical prostateetomy after 4 months of neoadjuvant endocrine therapy. Two cases of cT3 and 4 cT4 received castration. Pathological section from radical surgeries showed that 21 cases were organ confined and 7 were locally invasive. The difference of mean Gleason score between these two groups was significant in statistics. After 18 to 69 months (mean 42 months)follow-up, 21 organ confined cases were free survived, 4 locally invasive cases had biochemical recurrence and 1 case had multifocal bone metastasis. No cancer-specific death happened. Two of 4 cT4 cases were still alive and 2 died of the tumor. Conclusions Routine needle biopsy is necessary for the cases with“grave area”PSA of 4~10 ?g/L. Prostate cancers with PSA 4~10/?g/L are not always early diseases. Gleason score is a very important index for determine the stage of pathology after surgery. Radical prostatectomy is an effective treatment for organ confined disease.

Background Researches showed that the incidence rate of cataract is high in the nickel mining area. Nickel sulphate can apparently inhibit the metabolism and proliferation of human lens epithelium cells. But the study on the injury mechanism of nickel on lens is still seldom. Objective Present study was to investigate the effect of nickel sulphate on the lens of SD rats. Methods Forty-five SPF SD rats aged from 7 to 14 days were grouped randomly into subcutaneous injection group, intraperitoneal injection group and blank group. Nickel sulphate of 2 g/L ( 10 mg/kg) was subcutaneously or intraperitonealy injected for 45 days. The opacity of rat lens was examined under the slit lamp at two-week interval and scored based on the criteria of LOCS II and LOCS III. The rats were sacrificed in 45 days after experiment and the lens were obtained for the pathological examination. Result The mean score of the anterior subcapsule opacity of rat lens was obviously higher in subcutaneous injection group compared with blank control group with a significant difference between them (t= 14. 311, P < 0. 05 ) , but no significant difference in the anterior subcapsule opacity between intraperitoneal injection group and blank control group (t = 4. 355 , P>0. 05 ). The score of posterior subcapsule opacity of lens were evidently higher in both subcutaneous injection group and intraperitoneal injection group than the blank control group (t = 9. 316,P = 0. 004;t = 7. 464, P = 0. 009) ,so was the mean score of the anterior +posterior subcapsule opacities(t = 23. 387,P=0. 000;t= 10. 533,P = 0. 002) and the total score of rat lens opacity ( t = 12. 358 , P = 0. 001; t = 10. 188 , P = 0. 003 ) . No significant differences were found in cortex opacity score and nuclear opacity score among three groups ( P > 0.05 ). Histopathology examination revealed that the degeneration of lens collagen protein was more serious in subcutaneous injection group and intraperitoneal injection group than the blank control group,and the injury degree of lens collagen protein was more dominant in subcutaneous injection group. Conclusion System administration of nickel sulphate induced the injury of anterior and posterior subcapsule of lens in SD rat.

The purpose of this study was to evaluate the impact of callus induction and culture conditions on secondary metabolic diversity of the callus cell lines of traditional Chinese medicinal plant Glycyrrhiza sp. (Glycyrrhiza) by combined chemical analysis and HPLC fingerprint. These callus induction conditions included two Glycyrrhiza species, two types of explants, light and dark conditions, and two combinations of hormones. The evaluation was firstly based on the contents of total flavonoids in the callus by chemical analysis and one way ANOVA. The content of total flavonoids in callus was significantly (P < 0.05) influenced by Glycyrrhiza species, light condition, and the combination of hormones. The callus was further evaluated using diversity factor based on the comparison of HPLC fingerprints of these callus cell lines. Diversity factor varies significantly for calli induced under different conditions, with the highest being at 0.45 under light condition and combination of hormones. These results provide important knowledge for the selection of suitable callus cell lines for the production of pharmacologically important secondary metabolites or bioactive fractions by in vitro culture of Glycyrrhiza sp.
