The purpose of this review is to help people having a right attitude toward the health effects of expo-sure to extremely low frequency (ELF) electromagnetic fields. In this paper, epidemiological studies and animal studies in vivo were reviewed in order to evaluate the health impacts of exposure to ELF electromagnetic fields. The results show that the association between ELF electromagnetic fields and the risk of tumors as well as non-tumor health effects is very weak even uncertain.

Objective To investigate the diagnosis and treatment of primary retroperitoneal tumor,and improve the early correct diagnostic rate and the resection rate.Method 86 patients with primary retroperitoneal tumor(PRT) were analyzed by review of the clinical materials from 1990 to 2000.Results Abdominal or waist pain was the main symptom,and abdominal or waist mass was the main sign.52.6% percent of the patients got correct diagnosis before operation.62 cases were followed up,the 2-year survival rate for complete resection cases were 61.3%,while the patients who received palliative resection or biopsy died within one year.The resection rate of tumors was 81.3% in benign tumors and 37.7% in malignant tumors,the recurrent rates after complete resection were 15.4%,60%,respectively.Conclusions The earlier diagnosis,totally removal of tumors at first time,periodic examination after operation are three important ways.The operative treatment is very imperative for the patients with recurrence.

Objective To study the value of p27 and Ki-67 detection in differentiating benign from malignant thyroid follicular neoplasms. Methods Labelling index (LI) of thyroid neoplasms from thyroidectomy specimens were detected immunohistochemically Results The normal thyroid group had the highest expression of p27 , and the lowest expression of Ki-67. There was significant difference in the expressions of p27 and Ki-67 between follicular thyroid adenomas (FA) and follicular thyroid cancers (FTC) (P

Objective To investigate the changes of melatonin and cellular immunological function in children with febrile seizures and its clinical significance. Methods 50 children, including 23 cases with complex febrile seizure (CFS) and 27 cases with simple febrile seizure (SFS) , and 25 cases with upper respiratory infections children selected as control group were enrolled in this study. Serum melato- nin was measured by enzyme-linked immunosorbent assay (ELISA) and cellular immunological function was measured by flow eytomcter. Results The levels of serum melatonin in the 3 groups of CFS, SFS, control were(14. 91±2. 61) ng/L, (20. 72±2. 54) ng/L, (23.93± 2. Ol) ng/L, respectively. The melatonin levels in CFS children were significantly decreased than that in control group and SFS children (P <0. O1). CD3 + ,CD4 +, the ratio of CD4 + /CD8 + and CD8 + in CFS group were significantly decreased than that in control group and SFS group (P <0.01). The ratio of CD4 +/CD8 + in SFS group was significantly decreased than that in control group (P <0.05), but CD3 + ,CD4 + and CD8 + had no statistics significance among these groups(P >0. 05). The serum rnelatonin level were positive related withdecreaseddegreeofCD3+,CD4+ andtberatioofCD4+ /CDS+ (r≥0. 472, P <0.05). Conclusion The disorder cfcellular immunological function was possible related with the loss of serum melatonin, and the loss of serum melatonin maybe one of the reasons for febrile seizures relapse and brain injured.

Objective To study the effect and the mechanism of baicalin on invasion and metastasis of(human) hepatocellular line BEL-7402.Methods Human hepatocellular line BEL-7402 were cultured and treated respectively with 5,10,20 mg/L baicalin for 48 h.The invasion and adhesion of the BEL-7402 cells were examined in Boyden chamber,cell migration and morphology were also observed.The expression of MMP_(2),TIMP_(2),_()integrin ?_(1,)and E-cd proteins of human hepatocellular line BEL-7402 was determined by flow cytometry.Results Baicalin inhibited invasion,adhesion and migration of hepatocellular line BEL-7402 in vitro in a dose dependent manner(P

Objective:To participate in the anti-infection regimen adjustment and perform pharmaceutical care for one pneumonia patient after lung transplantation by clinical pharmacist to provide experience for individualized medication. Methods:Clinical pharma-cist adjusted the treatment plan and doses of immunosuppressive agents according to the patient' s conditions. Results: The infection was effectively controlled through optimizing the treatment plan. Conclusion:Pharmaceutical care for patients after lung transplantation performed by clinical pharmacists is helpful to both the recovery of patients and future appropriate drug use.

Objective] To study the Xin'an doctor Sun Yikui Sun Wenyuan basis four diarrhea cases, in order to reveal Sun Yikui diarrhea syndrome differentiation syndromes characteristics. [Method] With Sun Wenyuan basis of diarrhea four proven cases as example, the combination of Neijing, Treatise on Febrile Disease, the Synopsis, Mingmen theory, Danxi academic ideas and related works and academic thoughts of Sun's, interpretation of Sun's diarrhea cases, comprehensive analysis of the syndrome differentiation syndromes characteristics. [Results] From the Sun Wenyuan basis diarrhea in four cases to know Sun Yikui grasp of vital theories and Danxi academic thoughts, clinical cure, the doer phlegmy wet, dyspepsia, the accountability of virtual are of pixu(deficient spleen), kidney deficiency, with particular emphasis on the pathological factors of kidney Yang deficiency, the author was good at using insurance and pills, Erchen Decoction, Benefit-stomach Shengyang Moisture-penetration soup, Liujunzi Decoction and revised prescriptions. [Conclusion] Sun Wenyuan basis contained diarrhea basis, Sun's clinically curing diarrhea with outstanding characteristics, the curative effect is distinct, we should combine classical and Sun's works to conduct the thorough research to the related basis, broaden the clinical cure drainage, help to improve the ability of clinical treating diarrhea.
