Incidence of thyroid cancer has continuously increased in the last three decades globally. A similar trend of thyroid cancer incidence appeared in China. New cases and deaths of thyroid cancer in China accounted for 15.6% and 13.8% of the global new cases and deaths in 2012. The incidence in East China was the highest while that in Middle China was the lowest. Thyroid cancer was more common in urban areas than in rural counterparts. The incidence was substantially higher in female patients than male. Thyroid cancer occurred most commonly in middle age. Radiation exposure, iodine suffciency or deifciency, sex hormone and genetic mutations were risk factors for thyroid cancer. To prevent it, potassium iodide should be taken to prevent radiation fallout in nuclear accidents, unnecessary exposure to radiation from medical imaging is reduced, iodine surveillance system is improved and appropriate standards for iodized salt are established.

Objective To research the significanec of genes bel-2 and bax in chondrocyte apoptosis in experimental osteoarthritis in rabbits.Method Twelve New Zealand rabbits divided into two groups at random:model group and control group.Model group with osteoarthritis was duplicated by immobilizing with gypsum at extension position in right hind limb of rabbits.Rabbits of model group were executed after 6 weeks and chondrocytes were taken.Positive expression rate of bcl-2 and bax mRNA was measured by immunohisto- chemistry and Terminal deoxynucleotidyl transferase mediated dUTP nick end labeling(TUNEL).Results Positive expression rate of mRNA in bel-2 and bax of model group was obviously more than control group(P＜0.05).According to immunohistochemistry,and grey grade of positive expression of protein in bcl-2 and bax of chondrocytes in model group was lower and positive expression rate was gigher compared with control group (P＜0.05,P＜0.01).bcl-2 and bax of model group were lower than control group(P＜0.05).Conclusion Genes bcl-2 and bax participate and thus accelerate chondrocyte apoptosis of osteoarthritis together.

OBJECTIVETo observe the effect of low molecular weight heparin calcium (LMWHC) combined Compound Danshen Injection (DI) on nephrotic syndrome patients with early onset severe preeclampsia.

METHODSTotally 80 nephrotic syndrome patients with early onset severe pre-eclampsia were randomly assigned to four groups voluntarily, i.e., Group A (22 cases, treated by magnesium sulfate), B (19 cases, treated by magnesium sulfate plus LMWHC), C (21 cases, magnesium sulfate plus DI), D (18 cases, magnesium sulfate plus LMWHC and DI). Umbilical arterial S/D ratios, amniotic fluid index (AFI), prolonged gestational age, placenta weight, neonatal weight, and Apgar score were compared among the four groups.

RESULTSCompared with before treatment in the same group, umbilical arterial S/D ratios decreased in the four groups (P <0. 05). AFI decreased in Group A, while it increased in Group B, C, and D (P<0. 05). Compared with Group A at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group B, C, and D (P <0. 01 , P <0. 05). Prolonged gestational age and neonatal weight were increased in Group B, C, and D (P <0. 01, P <0. 05). Placenta weight were increased in Group B and D (P <0. 05). Apgar scores at 1 and 5 min were improved in Group D (P <0. 05). Compared with Group B and C at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group D (P<0. 05). Compared with Group B, prolonged gestational age and placenta weight were decreased in Group C, but prolonged gestational age and placenta weight were increased in Group D (P <0.05). Compared with Group C, prolonged gestational age, placenta weight, and neonatal weight were increased in Group D (P <0. 05).

CONCLUSIONTreatment of nephrotic syndrome patients with early onset severe pre-eclampsia by LMWHC combined DI could prolong gestational ages, obviously improve prenatal outcomes, with better effect obtained than using any of them alone.

OBJECTIVETo investigate the effects of hydrogen sulfide (H₂S) on oxidative stress and endoplasmic reticulum stress (ERS) in a rat model of diabetic cardiomyopathy (DCM).

METHODSThirty male SD rats were randomly divided into control group, diabetes group and treatment group( n = 10). Intraperitoneal injection of streptozotocin was utilized to establish a rat model of DCM. The rats with DCM in treatment group were intraperitoneally injected with NaHS solution. After treated for 12 weeks, the hearts isolated from rats were perfused on a langendorff apparatus. The ventricular hemodynamic parameters were measured. The ultrastructures of myocardium were observed using electron microscopy. The content of malondialdehyde (MDA), the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in myocardial tissue were determined by spectrophotometry. The expressions of C/EBP homologous protein( CHOP), glucose-regulated protein 78 (GRP78) and Caspase 12 at mRNA level in myocardium were detected using RT-PCR.

RESULTSCompared with control group, the cardiac function and myocardial ultrastructure were damaged obviously in diabetic rats. In myocardial tissue, the content of MDA was increased, while the activities of SOD and GSH-Px were decreased. CHOP, GRP78 and Caspase 12 mRNA expressions were increased significantly. Compared with diabetes group, cardiac function and myocardial ultrastructure damage were improved in treatment group. The content of MDA was decreased, while the activities of SOD and GSH-Px were increased significantly. The mRNA levels of CHOP, GRP78 and Caspase 12 were increased.

CONCLUSIONH2S can protect myocardium in diabetic rats, maybe it is related to reduce oxidative stress damage and inhibition of the ERS-induced apoptosis pathway.

To study the in vitro anti-angiogenesis effect of three curcumin pigments (curcumin, demethoxycurcumin, bisdemethoxycurcumin). In the study, the inhibitory effect of the three curcumin pigments on proliferation of HUVEC cells induced by OX-LDL and the effect on migration of HUVEC cells were detected. The effect on neovascularization was observed by chorioallantoic membrane (CAM) test. The effect on cell adhesion factors ICAM-1 and VCAM-1 of HUVECs were tested by Real-time RT-PCR. It was found that the three curcumins could inhibit the proliferation of HUVEC cells induced by OX-LDL within the dosage range 4, 8, 16 mg x L(-1), with a dose-dependence. The proliferative effect of curcumins on HUVECs was greater than the other two derivatives (P < 0.01). All of the three curcumin pigments inhibited the migration of HUVEC cells and the angiogenesis of chick chorioallantoic membrane (CAM). The migration inhibition rate of curcumins at middle and high concentrations was greater than the other two (P < 0.01). All of the three curcumin could down-regulate the expression of VEGF and ICAM-1, and curcumins showed more obvious effect in down-regulating VEGF than demethoxycurcumin and bisdemethoxycurcumin(P < 0.01); Bisdemethoxycurcumin showed the most significant effect in down-regulating ICAM-1 (P < 0.01). All of the three showed no remarkable effect on expression of VCAM-1, and only bisdemethoxycurcumin showed the down-regulating effect (P < 0.05). According to the findings, all of the three curcumin pigments could resist angiogenesis by inhibiting proliferation and migration of endothelial cells and down-regulating the expression of VEGF and adhesion molecules ICAM-1.

Objective To investigate the effects of mycoplasma pneumoniae(MP)infection on the exhaled nitric oxide level and lung function in asthmatic children,analyze the correlation between exhaled nitric oxide level and lung function and to provide reference for the treatment and monitoring of asthmatic children.Methods Sixty-eight children aged from 5 to 13 years old with mild or moderate asthma during June 2011 to January 2013 were collected.MP-IgG antibody,MP-IgM antibody,MP-DNA,total serum IgE,FeNO measurement and spirometry were examined on the next day morning.They were divided into two groups according to the pathogen:ashtma with MP group and ashtma without MP group.Then the levels of nitric oxide level and lung function indicators between the two groups were analyzed.Results The FeNO level in ashtma with MP group was significantly higher(P<0.05).There were no differences between two groups in lung function parameters such as FVC,FEV1,FEV1 / Vcmax,MEF25 and MEF50(P>0.05),but differnces were found in MEF75 and PEF(P<0.05).No correlation was found between FeNO levels and lung function parameters(FVC,FEV1,FEV1/Vcmax,MEF50,MEF25,MEF75 and PEF).Conclusion In asthma children with MP infection,the FeNO level was significantly increased and no correlation was found between FeNO levels and lung function.
