Objective To study the iodine deficiency disorders (IDD) situation in Wenzhou City during 1995-2014.Method According to National IDD Surveillance Project,IDD surveillance had been consecutively carried out during the past 20 years,which consisted of goiter rate in 8-10 years old children,iodized salt and urinary iodine levels.Results The goiter rate of 8-10 years old children was decreased from the highest of 31.09％ (2 190/7 043) in 1995 to the lowest of 2.28％ (77/3 378) in 2014;the highest level of median urinary iodine was 214.78 μg/L,and the lowest level was 74.48 μg/L,and which was increased from 74.48 μg/L in 1995 to 187.00 μg/L in 1996,and then had been maintained at the appropriate level recommended by World Health Organiation (WHO),except that in 1998,2003,2004 and 2006.The qualified rate of iodized salt was increased from 54.95％ (1 471/2 677) in 1996 to 95.52％ (2 548/2 754) in 1999,but decreased to 62.75％ (768/1 224) in 2003,however it was fluctuated from 78.61％ (2 503/3 184) to 92.48％ (2 989/3 232) from 2004 to 2013,and it was 90.43％ in 2014 (2 983/3 300).Conclusions The comprehensive measures for controlling IDD,with universal salt iodization,has been gradually achieved remarkable effect in Wenzhou City,but the non-iodization salt existing in the market is still a problem,and people have misunderstandings about iodization salt.Iodine supplementation had better be conducted according to local conditions and based on scientific policy.

Objective:To compare the efficacy and costs of pegylated recombinant human granulocyte colony stimulating factor (PEG-rhG-CSF) and granulocyte colony stimulating factor (G-CSF) for hematopoietic stem cell mobilization and hematopoietic recovery after transplantation in patients with relapsed or refractory malignant lymphoma. Methods:From July 2014 to October 2016, 15 patients with malignant lymphoma using peripheral blood stem cell mobilization (PBSCM) for autologous peripheral stem cell transplantation (APBSCT) were treated in our institution and enrolled in the PEG-rhG-CSF group (experimental group). We analyzed data from other 15 patients with malignant lymphoma mobilized with G-CSF who were treated in our institution from January 2013 to August 2015 (control group). Results:Patients in both groups were successfully mobilized. The median amounts of CD34+cells collected in the experimental and control groups were 16.2×106/kg and 8.9×106/kg, respectively (P=0.414), and the median amount of mononuclear cell (MNC) was 12.4×108/kg and 9.9× 108/kg, respectively (P=0.519). In the experimental and control groups, the mean durations of mobilization were 10.66±1.45 and 9.33±1.83 days (P=0.234), the mean durations of neutropenia during mobilization were 4.20±2.17 and 3.80±2.04 days (P=0.608), the mean durations of absolute neutrophil count recovery after APBSCT were 10.14±1.29 and 10.93±2.69 days (P=0.327), and the mean durations of platelet recovery were 10.36±2.27 and 12.27±3.38 days (P=0.121). Mobilization and hematopoietic recovery after APBSCT were not significantly different between the two groups. The cost was lower in the experimental group than that in the control group (RMB 3,960 yuan versus RMB 11,479.3±2,401.3 yuan). Conclusion:High-dose chemotherapy combined with PEG-rhG-CSF is a promising, effective, and low-cost mobilization regimen for patients with relapsed or refractory malignant lymphoma.

Objective To investigate prevalence of erectile dysfunction(ED)in type 2 diabetic male patients and to analyze its related factors.Methods A total of 904 married male patients with type 2 diabetes were involved in this study and they were interviewed with anonymous questionnaire.An international index of erectile function-5(IIEF-5)was used to determine the severity of ED by self-rating score in age,duration of diabetes,serum level of glycosylated hemoglobin A1c(HbA1c),history of alcohol drinking and smoking,blood pressure and anti-hypertensive medication in diabetic ED patients.Relationship between relevant factors and diabetic ED was analyzed.Results ED was diagnosed in 612 diabetics with prevalence of 67.7 percent(612/904)according to their total scores of IIEF-5.Logistic regression analysis showed that increase in duration of diabetes by five years,age by 10 years,serum level of HbAI c by 2%, systolic blood pressure by 30 mm Hg(1 mm Hg = 0.133 kPa),positive history of smoking and alcohol drinking were all independently associated with prevalence of diabetic ED,with OR of 1.96,1.25,2.32, 1.12,1.67(P

OBJECTIVETo establish a piglet model of acute hypoxic myocardial impairment.

METHODSNineteen newborn piglets were divided into two groups: control group (CON, n = 8) and asphyxia group (ASP, n = 11). In ASP group, asphyxia was induced by disconnecting the animal from the ventilator and clamping the inhalation tubing for 10 minutes. Six hours after cardiopulmonary resuscitation (CPR), the levels of serum creatine kinase MB (CK-MB) and cardiac troponin T (cTnT) were detected. Cardiac functions were evaluated by echocardiography. Parameters included left ventricular ejection fraction (LVEF), right ventricular ejection fraction (RVEF), ratio of peak E velocity and peak A velocity of mitral flow and tricuspid flow (MVE/A and TVE/A), ratio of peak velocity and a velocity of mitral annulus motion and tricuspid annulus motion (MVe/a and TVe/a), isovolumic relaxation time of left ventricle (LVIRT), index of mitral regurgitation and tricuspid regurgitation (MR and TR). The CON group was examined at the corresponding time points. The pathologic changes in piglets' hearts were examined. The myocardial histopathologic damage score (MHDS) was used to evaluate the severity of myocardial impairments.

RESULTSSix hours after CPR, the CK-MB and cTnT in ASP group [(423 +/- 156) IU/L and (0.85 +/- 0.64) microg/L] were both higher than those in CON group [(213 +/- 30) IU/L and (0.08 +/- 0.02) microg/L, P < 0.01]. The LVEF, RVEF, TVE/A, MVe/a and TVe/a in ASP group [(59.6 +/- 8.6)%, (60.2 +/- 7.1)%, 0.79 +/- 0.21, 0.77 +/- 0.12 and 0.78 +/- 0.19, respectively] were all lower than those in CON group [(67.5 +/- 6.9)%, (68.8 +/- 7.4)%, 1.14 +/- 0.16, 1.19 +/- 0.18 and 1.03 +/- 0.27, respectively, P < 0.05]. The MHDS in ASP group was higher (2.82 +/- 0.98) than that in CON group (0.38 +/- 0.53, P < 0.01), but no significant difference was observed in MHDS between the left ventricle and right ventricle.

CONCLUSIONAsphyxia can lead to obvious myocardial impairment in newborn piglet, which could be very useful for the studies of acute hypoxic myocardial impairment in the newborn infants.

OBJECTIVETo evaluate the effect of health education on lung function and quality of life in stabilized patients with chronic pulmonary disease (COPD).

METHODS117 stabilized COPD patients were randomly devided into 4 groups with numbers as 31,26, 20 and 40 identified as Groups 1 to 4. Patients in Group 1 did not receive health education, but Groups 2,3 and 4 received one, two, three or more times health education in file. FEV1, FEV1%, FEV1/FVC and SGRQ score were compared pre and 6-month post the health education program.

RESULTSHealth education seemed successful in delaying the decline of FEV1, FEV%, FEV1/FVC and groups 2-4 were superior to group 1(P < 0.05) while groups 3 and 4 were superior to groups 1 or 2(P < 0.05). Health education was effective in raising the SGRQ score among the stabilized COPD patients with groups 2-4 superior to group 1 (P < 0.05) while groups 3 and 4 superior to groups 1 or 2 (P < 0.05).

CONCLUSIONHealth education could effectively delay the decline of both lung function and quality of life in stabilized patients with COPD.

OBJECTIVETo investigate the characteristics of and relationship between occlusal plane and masticatory path in young adults with individual normal occlusion, and to provide clinical implications on both morphological and functional reference of occlusal plane location.

METHODSForty-three young adults with individual normal occlusion were included. Lateral projections of cephalometric radiographs were taken. The parameters of anatomical landmarks were analyzed. The BioEGN mandibular kinesiography analyzer was used to record the path of incisal edge of mandibular central incisor movement during mastication. The Pearson's linear correlation analysis was performed to analyze the relationship of inclination of occlusal plane and data mentioned above with SPSS13.0 software.

RESULTSThe inclination of occlusal plane (the angle between occlusal plane and Camper's line OP-CP) was (2.1 ± 3.8)° in youth with normal occlusion. Means of maximal distances of 3-dimensional masticatory mandibular movement paths were as follow: the vertical length was (20.22 ± 4.28) mm, the anterior-posterior width was (11.42 ± 2.45) mm, and the lateral width was (8.62 ± 1.52) mm. The inclination of occlusal plane was negatively correlated to the lateral width of masticatory path in frontal plane (r = -0.39, P < 0.05). Occlusal plane was approximately vertical to the opening and closing path in the vicinity of intercuspal position during mastication. The inclination of occlusal plane was positively related to occlusal plane-closing angles in the upper segments of closing path during mastication (P < 0.05). Masticatory axis angle was (66.50 ± 7.98)° with no significant correlation to the inclination of occlusal plane (P > 0.05).

CONCLUSIONSThese results suggest that the sagittal inclination of occlusal plane can influence 3-dimensional morphology of masticatory path.The inclination of occlusal plane has a guiding effect on masticatory movement in the upper segments of closing path.

OBJECTIVETo study the effect of parthenolide on the proliferation of vascular smooth muscle cell(VSMC) and its mechanism.

METHODVascular smooth muscle cell was cultured, the protein levels of c-fos, c-myc, p15, p16, p18, p19 were measured by Western blot method, cell cycle were examined with flow cytometry, and the DNA synthesis was determined by [3H]-TdR incorporation.

RESULTParthenolide inhibited protein levels of c-fos, c-myc in a time-dependent manner but didn't affect the protein levels of p15, p16, p18, p19. Flow cytometric DNA analysis revealed that parthenolide increased significantly G0/G1 phase of VSMC and decreased S phase of VSMC in a dose-dependent manner. Parthenolide inhibited [3H]-TdR incorporation in a dose dependent manner.

CONCLUSIONParthenolide may inhibit proliferation of VSMC by inhibiting the expressions of c-fos, c-myc, but not the expressions of p15, p16, p18, p19.
