Thyroid cancer is the most common malignancy in the endocrine system .In recent years ,the incidence of thyroid cancer has increased year by year ,which sparked people′s attention.With the development of thyroid cancer research ,it is found that cytokines play a key role in the occurrence and development of tumor .At present ,the cause of thyroid carcinoma and mechanism is not yet entirely clear ,however ,the occurrence of thyroid cancer is possiblely associated with the body regulating cellular immune dysfunction .Cytokines play an important role in the whole process ,in which the relationship between cytokines IFN -γ,IL-6 and thyroid carcinoma is closely related .

OBJECTIVE:To evaluate the effects of compound amino acids capsul es on hypoalbuminemia in patients with chronic renal failure undergoing hemodialysis.METHODS:30hemodialysis patients were selected to orally take2compound amino acids capsules(0.35g per capsule)twice daily for12weeks,renal and liver function and levels of serum albumin and pre-albumin were measured before and after the experiment.RESULTS:The levels of serum albumin and pre-albumin were increased significantly after the treatment,it were(30.5?4.6)g/L vs(35.9?7.1)g/L,and(213.0?46.9)mg/L vs(275.8?52.3)mg/L respectively(P

BACKGROUND:Bone marrow mesenchymal stem cells have beneficial effects on the treatment of various diseases. Mitochondria transfer is newly proposed and its specific mechanisms of action and control factors remain unclear.
OBJECTIVE:To review the studies about stem cells and mitochondrial transfer, then to discuss its value on clinical.
METHODS:The PubMed, VIP and Wanfang databases were searched for related articles concerning stem cells and mitochondrial transfer. Key words were“stem cell, embryonic stem cell, progenitor cell, mitochondria”in Chinese and“Stem cell[s], Mother cell[s], Progenitor cell[s], Colony-Forming Unit[s], Colony Forming Unit[s], Mitochondria[l] transfer”in English. Thirteen articles were found initial y, and using the citation tracking method, final y 42 articles were determined. RESULTS AND CONCLUSION:Studies have shown that mitochondrial transfer from bone marrow mesenchymal stem cells is associated with rescue of aerobic respiration and restoration of mitochondrial function in the injured somatic cells. Bone marrow mesenchymal stem cells and recipient cells form tunneling nanotubes for mitochondrial transfer. Movement of mitochondria between cells is regulated and directed by Miro1. The successful transfer of mitochondria may be accompanied with the clearance of damaged mitochondria. The rescue of mitochondrial function in early stages may provide a valuable therapeutic strategy for various diseases include acute lung injury.

Objecfive To investigate the prevalence of Ureaplasma urealyticum(UU)and Mycoplasma hominis(MH)infections in urogenital tract and their sensitivities to drugs in Qinhuangdao area from 2006 to 2007.Methods UU and MH were detected by Mycoplasma IST kits in urine samples from 3062 patients suspected as urogenital tract infection and the sensitivity tests for 8 antimicrobial agents were performed.Results Mycolasmas were detected in 1262 patients from 3062 patients suspected as urogenital tract infection,in which 1037 were of UU infection,41 were of MH infection and 184 were of UU+MH infection.Both strains were sensitive to josamycin,doxycycline and tetracycline,but were less sensitive to ofloxacin and ciprofloxacin.Conclusions Drug resistance is increasing for Mycoplasma and sensitivity test is important in treatment of urogenital tract infection by Mycoplasma.

Objective To investigate the survival rates of main malignant tumors in Nanhui district. Methods Total 5 783 cases, registered as new cases with malignant neoplasm from 2002 to 2004 in Nanhui, were followed up. Data was studied by survival analysis with SPSS 13.0 of life table and Kaplan -Meier. Results The average annual crude incidence of malignant tumors was 267.57 / 100 000, the World standardized incidence rate of 209.98 / 100 000. Cancer Incidence in the top five ranks followed by lung, liver, stomach, colon and esophageal cancer, the incidence was 43.06 / 100 000, 28.65 / 100 000, 26.82 / 100 000, 18.63 / 100 000 and 9.57 / 100 000, respectively. The difference of the survival rates between the top five cancers was remarkable. Survival rates of cancers among males from the lowest to the highest were liver, lung, esophagus, stomach and intestines. Survival rates of cancers among females from the lowest to the highest were of liver, lung, esophagus, stomach, intestines, cervical and breast. The male or female main cancer's relative survival rate droped along with the age rising. Conclusion The survival status was better in the patients with intestine cancers and female patients with breast cancer, but worse in patients with liver, ung and esophageal cancer.

Objective To know the distribution of arsenic and trace elements in drinking water in the endemic arsenism areas in Shanyin County, Shanxi Province. Methods Drinking water samples were collected from the chronic endemic arsenic poisoning areas of Silizhuang and Shanghexi, Shanyin County, Shanxi Province and HPLC-HG-AFS system was used to analyze the arsenic contents, valence and speciation. The trace elements were determined by ICP-MS. The data were analyzed by SPSS13.0 for windows. Results A total of 63 drinking water samples were determined, 39.68% of them exceeded the standard limit of arsenic level, inorganic arsenic was the main arsenical in drinking water, iAs3+/(iAs3++iAs5+) ratio was 56.17% in the water sample (arsenic was higher than 50 ?g/L) . The contents of Fe, Mn, Hg, Se and Pb in part of drinking water samples exceed the standard limits. No significant difference was seen between the arsenic results determined by HPLC-HG-AFS and ICP-MS. Conclusion Arsenic contamination of drinking water in Shanyin County, Shanxi Province is severe. The most frequently seen arsenic valence state in drinking water is iAs3+. Some trace elements in part of drinking water samples exceed the standard limits, this may aggravate arsenic poisoning.

Objective To investigate the effects of arteriovenous fistula on structure and function of left ventricle in patients with maintained hemodialysis. Methods Levels of hemoglobin, inter-hemodialysis weight increase, blood pressure, diameter and blood flow of the fistula, structure and function of left ventricle were examined before and 12, 24 months after hemodialysis treatment in 44 patients who were divided into group A(low flow group, 900 ml/min) based on the fistula flow at the 24th month. Results Left ventricular end-diastolic diameter (LVDd), interventriculare septal thickness (IVST) and left ventricular mass index (LVMI) increased gradually as the time of hemodialysis going on. The cardio-cheat proportion also increased as well as ejection fraction (EF) and the peak velocity ratio of early and late diastolic period(E/A), especially significantly increased in group B. Cardio-chest proportion , LVDd and LVMI were higher and E/A lower in patients with severe sodium retention than those with mild sodium retention in both groups. The fistula flow was positively related to LVDd and LVMI( P

Objective To observe the clinical disinfection effect of root canal with non-filling medication.Methods 50 patients who required root canal therapy for apical period(acute or chronic) or pulp necrosis were involved in the study.Non-filling medication on the root canals were taken bacteria from the root canals were collected and cultured before and after the treatment.Results Bacteria were detected in every specimen,which were mixture of aerobes and anaerobes.One week later,only two strain were detected in two specimen.Conclusion Non-filling medication can be used as an effective disinfection to sterilize root canal.
