Objective To investigate the relationship between the content of iodide in water and children goiter in the high iodide areas. Methods Pupils aged 8-10 years from 17 primary schools in 10 towns of Huimin county, Yangxin county, Wudi county, Bincheng county were chosen. Based on the contents of water iodide,the pupils were divided into groups, the prevalence of goiter and the content of urinary iodide were determined. Results The prevalence of goiter in the children aged 8-10 was 18.8%,the prevalence showed an increasing tendency. In a certain range, increase of content of iodide in water did not caused an increased prevalence of goiter. There was no association was found between the content of iodide in water and the prevalence of goiter. Conclusion According to the results of the present paper, despite the contents of iodide in drinking water meets the standard of high iodide area, there is still no dose-effect relationship between the prevalence of goiter in the children aged 8-10 years and the content of iodide in water, whereas as the high iodide exposure time prolong, the prevalence of goiter demonstrates an increase tendency.

BACKGROUND: Homocysteine (HCY) has been verified as an independent risk factor of atherosclerosis and atherothrombosis of cardiovascular disease.OBJECTIVE: To observe the effects of HCY on the secretion and activity of matrix metallopotinase-1 (MMP-1) and tissue inhibitors of metalloproteinase-1 (TIMP-1) in vascular smooth muscle cells (VSMCs).DESIGN : Auto-control observation.SETTING: Pathology Room, Institute of Regeneration Medical Sciences, Jilin University.MATERIALS: In vitro cultured vascular smooth muscles cells (VSMCs) of rats were obtained from male Wistar rats with the body mass of about 150 g from weeks 4-6 supplied by Laboratory of Animals, Norman Bethune Medical Sciences Division, Jilin University.METHODS: The experiment was performed at the Pathology Room, Institute of Regeneration Medical Sciences, Jilin University from May 2001 to May 2003. VSMCs ofin vitro cultured rats were adopted and divided into 5 groups, 0(control group), 0.10, 0.25, 0.50 and 1.00 mmol/L HCY were added, respectively for 48 hours. Effect of HCY on activity of MMP-1 was observed with zymography. The secretions of MMP-1 and TIMP-1 and their mRNA expressions were studied with Western blot and semi-quantitative reverse transcription polymerase chin (RT-PCR).MAIN OUTCOME MEASURES: Activity of MMP-1, secretions of MMP-1 and TIMP-1 and their mRNA expressions.RESULTS: ①Secretions of MMP-1 and TIMP-1: The secretion of MMP-1 in the 0.25, 0.50 and 1.00 mmol/L HCY groups was lower significantly than that in the control group (P ＜ 0.05-0.01). The secretion of TIMP-1 in the 0.10, 0.25, 0.50 and 1.00 mmol/L HCY groups was higher than that in the control group (P＜ 0.05-0.01). ②The MMP-1 activity decreased with the increase of HCY, but reduced obviously in the 0.50 and 1.00 mmol/L HCY groups (P ＜ 0.01). ③The expression of MMP-1 mRNA in the 4 HCY groups was lower markedly than that in the control group (P ＜ 0.01). The expression of TIMP-1 mRNA in the 0.25 mmol/L HCY group was higher than that in the control group (P ＜ 0.05), and it was higher remarkably in the 0.50 and 1.00 mmol/L HCY groups than that in the control group (P ＜ 0.01).CONCLUSION: HCY can inhibit enzyme activity, decrease collagen degradation and induce collagen accumulation by inhibiting the secretion of MMP-1, which indicates that reduction of collagen degradation induced by HCY is one of the pathogenesies of atherosclerosis.

Objective To investigate the influence of combined thrombolysis therapy on clinical effects for short -and long -term of patients with acute cerebral infarction caused by sudden occlusion of anterior and posterior circulation.Methods 75 patients with cerebral infarction caused by sudden occlusion of anterior and posterior circulation were chosen and divided into A group (46 patients)with sudden occlusion of anterior circulation and B group (29 patients)with sudden occlusion of posterior circulation by comprehensive therapy for intra -arterial thrombolysis combined with mechanical crushing and dilation.The recanalization rate,the excellent and good rate of ADL -Barthel score,NIHSS score and GCS score before and after treatment,intracranial hemorrhage rate and mortality rate of two groups were compared.Results The recanalization rates of A group and B group were 50.00%(23 /46), 89.66%(26 /29).After treatment,the excellent and good rates of ADL -Barthel score of A group and B group were 58.70%(27 /46),62.07%(18 /29).The recanalization rate of B group was significantly higher than A group(χ2 =7.44,P <0.05).There was no significant difference in the excellent and good rate of ADL -Barthel score after treatment between the two groups(χ2 =1.21,P >0.05).After treatment,the NIHSS scores of A group and B group were (8.66 ±2.48)points,(8.72 ±2.51 )points,the GCS scores of A group and B group were (12.89 ± 3.61)points,(13.10 ±3.72)points.There were no significant differences in NIHSS score and GCS score after treatment between the two groups(t =1.47,1.52,all P >0.05).After treatment,the intracranial hemorrhage rate of B group was significantly lower than A group (χ2 =8.16,P <0.05 ).There was no significant difference in the mortality rate between the two groups(χ2 =0.98,P >0.05).Conclusion Compared with acute cerebral infarction caused by sudden occlusion of anterior circulation,combined thrombolysis therapy in treatment of patients with sudden occlusion of posterior circulation has advantages including higher recanalization rate and lower risk of intracranial hemorrhage.

Objective To study the relationship between intradialytic hypertension (IDH) and inflammatory factors in patients with maintenance hemodialysis.Methods Forty maintenance hemodialysis patients were involved,including 20 patients with IDH (IDH group) and 20 patients without IDH(non-IDH group) during hemodialysis.All of them had no sign of acute infections or other progressive disease.The levels of C-reactive protein (CRP),interleukin (IL)-1 β,IL-6,tumor necrosis factor (TNF)-α were measured by enzyme-linked immunosorbent assay (ELISA) before hemodialysis and 1,2,4 h after hemodialysis.The correlation of hypertension to CRP,IL-1 β,IL-6,TNF-α was analyzed.Results The levels of CRP,IL-1β,IL-6,TNF-α were increased in IDH group with the progress of hemodialysis,but were stable innon-IDH group.Logistic regression analysis indicated that there were positive correlations between CRP (r =0.3652),IL-1β (r =0.3261 ),IL-6(r =03156),TNF- α (r =0.3324) and blood pressure during hemodialysis (P ＜ 0.01 ).Conclusion The levels of CRP,IL-1β,TNF-α,IL-6 are positively related to the IDH in maintenance hemodialysis patients.

Objective:To evaluate the effect of presurgical nasal mode(PNM)combined with nasal diorthosis in the treatment of na-sal deformity and incomplete unilateral cleft lip(IUCL)in infants.Methods:35 infants with IUCL were treated by PNM followed by nasal diorthosis and cheiloplasty.The nasal asymmetry was analysed by measurments of nostrils height,nostrils width and nasal colu-mella angle skewness on the photographs at the initial visit(T0),pre-operation(T1),1 week after operation(T2),1 month after opera-tion(T3)and a year after operation(T4).The other 35 infants with IUCL without PNM treatment were served as the controls.Re-sults:Compared with the controls,the symmetry of nostrils height,nostrils width,nasal columella angle skewness in PNM treated children were significantly improved at T0-T1 and T1-T2(P ＜0.05).there was no significant difference at T2-T3 and T3-T4(P >0. 05).Conclusion:Nasal asymmetry can be improved by presurgical nasal mode treatment followed by preliminary nasal deformity di-orthosis and cheiloplasty.

Objective To explore the related risk factors of cerebral hemorrhage complicated with stress ulcer (SU). Methods The clinical data of 1 185 patients with cerebral hemorrhage admitted to Department of Emergency Medicine of Nanjing General Hospital from March 2006 to March 2014 were retrospectively analyzed. Patients were divided into two groups according to whether patients complicated with SU or not. Data was collected within 8 hours after admission in two groups including gender,age,amount of bleeding,the bleeding site (basal ganglia,thalamus, brainstem,brain lobe,ventricle,subarachnoid,and cerebellum),disturbance of consciousness,acute physiology and chronic health evaluationⅡ(APACHEⅡ)score,systolic blood pressure(SBP),history of hypertension,and history of cerebral hemorrhage. The statistically significant risk factors found using univariate analysis was selected and was analyzed to find independent risk factors with multivariate logistic regression analysis. The receiver operating characteristic curve (ROC curve)was plotted to analyze the independent risk factors and evaluate their power of test. Results 1 185 patients with cerebral hemorrhage were enrolled in the study,293 cases occurred SU,accounting for 24.7%,and 892 cases without SU,which accounted for 75.3%. As shown by univariate analysis,risk factors for cerebral hemorrhage complicated with SU included age,amount of bleeding,the bleeding site,disturbance of consciousness,APACHEⅡscore,SBP. As to the site of bleeding,brain,thalamus,brainstem hemorrhage complicated with SU were higher proportion,45.3%(43/95),39.1%(63/161),36.9%(48/130),which were significantly higher than those of the lobes of the brain 〔26.2% (33/126)〕,cerebellum 〔18.8% (15/80)〕,basal ganglia〔16.1%(78/485)〕,arachnoid the inferior vena cava 〔12.0% (13/108)〕. Multivariate logistic regression analysis showed that amount of bleeding 〔odds ratio (OR)=3.305,P=0.001,95%confidence interval (95%CI)2.213-48.634〕,the bleeding site (OR=1.762,P=0.008,95%CI 0.123-2.743),SBP (OR=1.223,P=0.034,95%CI 0.245-2.812) were independent risk factors of cerebral hemorrhage complicated with SU. The area under the ROC curve (AUC)of amount of bleeding and SBP were 0.846 and 0.597,suggesting that amount of bleeding has moderate diagnostic value and SBP has low diagnostic value. Conclusions Cerebral hemorrhage patients with large amount of bleeding,the bleeding site in the ventricle,thalamus or brainstem,high SBP are of great risk. We should lower blood pressure and give preventive treatment for SU as soon as possible.

Objective:To investigate the risk factors of citrate accumulation in patients with liver failure treated with regional citrate anticoagulated continuous renal replacement therapy (RCA-CRRT).Methods:The clinical data of liver failure patients with RCA-CRRT admitted to department of intensive care unit (ICU) of Nantong Third People's Hospital from January 2017 to June 2020 were retrospectively analyzed. The selected patients were divided into citrate accumulation group and control group according to whether there was citrate accumulation (serum total calcium/free calcium ratio ≥ 2.4) during CRRT. The age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), mean arterial pressure (MAP), norepinephrine (NE) dose, blood lactic acid (Lac) concentration, liver function status, citrate dose, filter time and prognosis of the patients were compared between the two groups. Unconditional Logistic regression was used to analyze the risk factors for citrate accumulation.Results:Among 48 patients with RCA-CRRT and liver failure, 20 patients had citrate accumulation (accumulation group), and a total of 96 CRRTs were performed; the remaining 28 patients did not have citrate accumulation (control group), a total of 106 CRRTs were performed. There were no significant differences in age and APACHEⅡ score between the two groups. Compared with the control group, the MAP in the accumulation group was lower [mmHg (1 mmHg = 0.133 kPa): 66.9±13.6 vs. 86.4±8.3, P = 0.032], and the dosage of NE (μg/min: 16.3±8.4 vs. 5.9±2.8, P = 0.015) and lactic acid level (mmol/L: 4.89±1.45 vs. 2.98±0.87, P = 0.004) were higher, the damage of liver function was more serious [total bilirubin (TBil, μmol/L): 220.4±45.2 vs. 163.4±43.8, P = 0.012; Child-Pugh score: 12.0±2.5 vs. 8.8±1.4, P = 0.029; model for end-stage liver disease (MELD) score: 31.30±8.22 vs. 21.78±6.40, P = 0.041], hourly citric acid dosage (mmol/h: 27.4±6.9 vs. 19.3±4.9, P = 0.032) and total citric acid dosage (mmol: 3 393±809 vs. 1 819±502, P = 0.039) were higher. Although there were no significant differences in the length of ICU stay, total length of hospitalization stay and cost of hospitalization between the two groups, the 28-day mortality of the accumulation group was higher than that of the control group (60.0% vs. 28.6%, P = 0.039). Unconditional Logistic regression analysis showed that MAP [odds ratio ( OR) = 2.901, 95% confidence interval (95% CI) was 0.921-19.493, P = 0.019], NE dosage ( OR = 2.098, 95% CI was 1.923-12.342, P = 0.002), Lac level ( OR = 5.201, 95% CI was 3.211-9.433, P = 0.012), Child-Pugh score ( OR = 1.843, 95% CI was 0.437-7.420, P = 0.018), MELD score ( OR = 3.012, 95% CI was 0.384-12.843, P = 0.031), hourly citric acid dosage ( OR = 4.254, 95% CI was 1.734-11.839, P = 0.011) and total citric acid dosage ( OR = 4.109, 95% CI was 1.283-18.343, P = 0.001) were risk factors for citrate accumulation. Conclusion:In patients with tissue hypoperfusion and severe liver function damage, citrate anticoagulation should be avoided or the dosage of citric acid should be reduced, in order to avoid citrate accumulation.

Objective Acute coronary syndrome ( ACS) is frequently accompanied by chronic comorbidities , which may se-riously affect its prognosis .This study aims to investigate the value of the Charlson Comorbidity Index ( CCI) in predicting the outcome of ACS by assessing the impact of individual and post-weighted-assignment comorbid conditions of the disease . Methods We retro-spectively analyzed the clinical data on 1 096 cases of ACS treated in Jinling Hospital from January 2010 to March 2014 .We reviewed their general information , clinical presentations , complications , and previous treatments , calculated CCI , and used in-hospital mortali-ty as the index for judging the prognosis . Results Of the 1 096 patients, 73%were males (aged 64.2 ±12.9 years), 27% were females (aged 72.1 ±12.6 years), and 46.8% had comorbidities. Of the diseases included in the CCI system , previous myocardial infarction was the most frequent comorbidity (18.0%), followed by diabetes mellitus ( 14.7%), moderately to severe renal disease (7.1%), cerebrovascular disease (6.0%), and chronic lung dis-ease (6.0%).Single factor analysis revealed statistically significant differences between different CCI groups in such clinical indicators as history of coronary artery disease , history of hypertension , time between symptom onset and admission , hemodynamics , drugs adminis-tered (aspirin, P2Y12 blockers, ACEI/ARB or statins), and reperfusion therapy (P<0.05).Logistic regression analysis showed the strongest predictors of in-hospital mortality were heart failure (OR 1.88, 95%CI:1.57-2.25), metastatic tumor (OR 2.25, 95%CI:1.60-3.19), renal disease (OR 1.84, 95% CI:1.60-2.11), and diabetes mellitus (OR 1.35, 95% CI:1.19-1.19). Receiver operating characteristic curve analysis manifested that either CCI with age or CCI with age and gender was superior to CCI a -lone in predicting in-hospital mortality of ACS patients (AUC 0.761 [95%CI 0.748-0.773] and 0.756 [95%CI:0.743-0.768] vs 0.670 [95%CI:0.656-0.685]). Conclusion Heart failure, diabetes mellitus, renal disease, and metastatic tumors contrib-ute to the in-hospital mortality of ACS patients .CCI together with age and gender may help to assess the prognosis of the disease .
