Objective To analyze the relationship between the urine iodine level in different pregnant periods of women and the thyroid function .Methods The pregnant women were randomly sampled in Foshan city and 490 cases were selected as the research subjects ,including 170 cases of early stage pregnancy ,162 cases of middle stage pregnancy and 158 cases of late stage pregnancy . According to the thyroid function ,490 subjects were divided into the normal thyroid function group and the abnormal thyroid func‐tion group .Results 140 cases(88 .61% ) in the late stage pregnancy had normal thyroid function ,which were less than 166 cases (97 .65% ) in the early stage pregnancy and 157 cases (96 .91% ) in the middle stage pregnancy ;the constituent ratio of urine iodine < 100 μg/L in the early stage pregnancy was 19 .88% (33/166) in the normal thyroid function ,which was lower than 75 .00%(3/5) in the abnormal thyroid function group .The constituent ratio of urine iodine 100 - 300 μg/L in the early stage pregnancy group was 56 .0% (93/166) ,which was higher than 0 .0% (0/4) in the of abnormal thyroid function group .Conclusion It is neces‐sary to conduct the urinary iodine monitoring in early pregnant woman ,moreover it is suggested that the thyroid function detection will be conducted in the pregnant women with urine iodine < 100 μg/L and urine iodine 100 - 300 μg/L .

Objective To investigate the influencing factors for knowledge,attitude and practice(KAP)of the Three-manager mode about hierarchical medical system of Chronic diseases of the community residents in Xiamen,and provide references for the implementation of hierarchical medical system.Methods Multi-stage random sampling method was adopted,and 400 residents were randomly sampled from 5 communities of Xiamen for questionnaire survey.The survey features the dependent variable of the community residents′ knowing and joining-in the Three-manager mode,the internal factors(social demographic characteristics),and the external factors(medical expenditure and healthcare insurance).On such basis,four logistic regression models were built for analysis of such influencing factors.Results 41.10% of the surveyed were aware of the Three-manager mode,and 39.71% of the hypertension/diabetes patients among them joined in the hypertension network or diabetes network.Age,education,medical expenditure and referral experiences were significant influencing factors for KAP level of the Three-manager mode,while the residents of older age,higher education and referral experiences were high in their KAP;those of lower per capita monthly income,hypertension or diabetes,with coverage of medical insurance and satisfied with medical consultation in community were high in their awareness of Three-manager mode.Conclusions The KAP level of Three-manager mode of the community residents in Xiamen is acceptable,yet expected of further improvement.Room of further improvement includes enhancement of synergy of the Three-manager mode,enhanced motivation of government financial support and medical insurance,better service functions of community institutions,and especially the construction of hierarchical medical system.

Objective To estimate the status of understanding hierarchical medical mode in chronic disease management among medical staff and residents in Xiamen .Methods The multi-stage sampling was used in the study to select 49 physicians from the tertiary hospitals , 58 general practitioners ( GPs ) and health managers from 5 community health services centers , and 499 residents from 5 communities in Xiamen.We conducted a face-to-face survey to estimate their basic information , recognition for hierarchical medical mode , and patients'willingness for community first contact care .The data was described by mean value of frequency and constituent ratio , the chi-square test or Fisher's exact test was used for comparison among groups .Logistic regression was performed to analyze the factors influencing the residents 'preference for treatment in community medical institutions . Results The physicians from tertiary hospitals or community health service centers were almost all familiar with Xiamen mode (91/107, 85%), and more than half of them knew about the hierarchical medical system (67/107, 62.6%), 86.9% (93/107) of them knew about the guide of hierarchical medical system , 58.9%(63/107) of them received the relative training before .The physicians from community had higher knowledge , more frequency training , more referral experiences and more effective evaluation than the physicians from hospitals (all P<0.05).In our study, 86.2%(344/399) of residents were willing to see doctors in community health centers and 77.9%(311/399) of them were willing to return to community health service centers from tertiary hospitals for disease convalescence or chronic disease management;53.6% (214/399) of residents preferred to utilize community first contact care when they got chronic diseases , and they were more satisfied with the consultation and diagnosis process in community .The residents who knew about the hierarchical medical system were more likely to utilize community first contact care and return to community for medical care . However, the female or the higher-income residents were less likely to see doctors in community .Patients who had experienced transfer to community or had higher satisfaction to community care were more willing to return from hospitals to community for disease convalescence .The mode showed that the system was more effective in measuring and controlling blood pressure or blood glucose for patients who joined the patients 'network than for those did not join.(P<0.05).Conclusion Medical staff are familiar with hierarchical medical system , and the residents are likely to use community health service as their first contact care in Xiamen.The utilization of community first contact care is influenced by sex , family income, previous experience, knowledge of the system , and satisfaction to the system of patients .

Objective To investigate the effects of early intensive therapy on P cell function and long-term glycemic control in newly diagnosed type 2 diabetic patients with different recruiting fasting plasma glucose (FPG) levels.Methods A total of 382 newly diagnosed type 2 diabetic patients with FPG 7.0-16.7 mmol/L were randomly assigned to therapy with insulin in the form of continuous subcutaneous insulin infusion (CSII) or multiple daily injection (MDI) or oral hypoglycemic agents (OHA, by using gliclazide and/or metformin) for initial rapid correction of hyperglycemia.The treatments were stopped after euglycemia had been maintained for 2 weeks.The patients were followed longitudinally on diet alone for 1 year.Intravenous glucose tolerances tests (IVCTTs) were performed and blood glucose, insulin and proinsulin were measured before and after therapy as well as at 1-year follow-up.Homeostasis model assessment ( HOMA) of β cell function and insulin resistance index ( HOMA-β and HOMA-IR ) were calculated.All the patients were stratified on the recruiting FPG: stratum A (7.0 mmol/L≤ FPG < 11.1 mmol/L) , stratum B (11.1 mmol/L≤ FPG ≤ 16.7 mmol/L).Results More patients in stratum A achieved target glycemic control (94.4% vs 89.8% ) and in shorter time [(5.9 ±3.8)d vs(6.9 ±3.6)d, P <0.05] as compared with those in stratum B.B cell function represented by HOMA-β and acute insulin response ( AIR) improved significantly after intensive interventions in both stratum A and B patients.However, the remission rate at 1 year was significantly higher in stratum A patients (47.8% ) than those in stratum B (35.7%, P < 0.05).The patients treated with insulin (especially with CSII) had higher remission rates and better improvement of AIR at 1 year follow-up irrespective of the recruiting FPG (CSII or MDI vs OHA: 57.1% , 51.8% vs 32.8% in stratum A, P <0.05; 44.4% , 38.7% vs 18.6% in stratum B, P <0.05).Conclusions Compared with OHA, early short time intensive insulin treatment had more favorable outcomes on maintaining AIR and prolonged glycemic remission in newly diagnosed type 2 diabetic patients irrespective of the recruiting FPG levels.

Objective To establish a multi-regression workload model based on surgical related factors.Methods The routine surgery workload was measured by the RBRVS development process of Hsiao WC,and multiple regression models were established for the operative factors from the surgical project specifications,pricing regulations and the operative workload.Results Top workload factors of an operation were technical difficulty,surgical classification and time cost.Multiple regression equation R2=0.699.One degree increase of technical difficulty would push up workload by 0.034;one level of operation grade would raise workload by 0.793;and every one hour longer of the operation time would increase workload by 1.025. Conclusions Operations of higher level, technical difficulty and longer time cost should deserve more reimbursement in consideration of both pricing and income distribution.

In order to curb the excessive growth of medical expenses, the United States has initiated payment reform of diagnosis-related groups (DRG) since 1983, and developed a series of complementary measures to address issues such as overcoding and declining healthcare service quality which were exposed during the reform. The authors discussed the implementation of DRG payment reform in the United States, namely the case-mix specialization of medical institutions and the reduction of costs, as well as the relationship between the two. On this basis, the authors suggested that when implementing reforms to the medical insurance payment system in China, it is imperative to avoid such loopholes as overcoding by medical institutions and excessive pursuit of efficiency at the expense of quality control, as well as the decline of comprehensive rescue capability and quality of care incurred by the exacerbated specialization.

Objective To investigate the promotion effect of Danhong injection (DH) on brain-derived neurotrophic factor (BDNF) expression in Schwann cells (SCs) of SD rats.Methods In experiment of SCs apoptosis induced by advanced glycation end products (AGEs),SCs were divided into control group,AGEs treatment group and DH+AGEs treatment group; 48 h after each treatment,the SCs count was compared.In experiment of DH affecting mRNA and protein BDNF expressions in SCs,real time-PCR and Western blotting were used.In the experiment of DH combined with different inhibitors (Calphostin C,LY294002,H89,U0126,FR180204 and SB203580) affecting mRNA BDNF expression in SCs,real time-PCR was used.Results The number of SCs in AGEs treatment group was significantly decreased than that in the control group,but that in DH+AGEs treatment group was statistically increased than that in AGEs group (P＜0.05).The mRNA and protein expressions of BDNF in the DH treatment group were significantly increased than those in the control group (P＜0.05).As compared with DH group,DH+Calphostin C treatment group had significantly decreased BDNF mRNA expression (P＜0.05); BDNF mRNA expression in the DH+U0126,DH+FR180204 and DH+SB203580 treatment groups was significantly decreased as compared with that in the DH treatment group (P＜0.05).Conclusions DH could effectively inhibit SCs apoptosis induced by AGEs and significantly promote BDNF expression;protein kinase C (Calphostin C) and mehtyl ethyl ketone (U0126)/extracellular regulated protein kinases (FR180204EK)/p38 (SB203580) may be the important signaling transconduction pathways for BDNF expression.

Impaired eady phase insulin secretion is an important reason for leading to postprandial hyperglycemia.Nateglinide is a rapid-acting insulin secretagogue,which reduces postprandial blood glucose of type 2diabetic patient by restoring early phase insulin secretion.The efficacy and safety have been fully verified by clinical administration and it is more widely used to treat type 2 diabetic patients.Both sulfonylureas and glinides were named insulin secretagogue agents and regarded as alternative first-line drugs in the 2010 Chinese Guideline for treatment of type 2 diabetes.AACE/ACE Consensus statement claimed that glinides would be one of the important choices after metformin.In order to further guide the clinical application of nateglinide,16 national specialists in the field of endocrinology and metabolism of China discussed,drafted,and edited this consensus.The current consensus combined clinical evidences at home and abroad.systematically reviewed and summarized tlle results of these studies about nateglinide.It will provide guiding recommendations and reference concerning how to reasonably and effectively use nateglinide in the clinical practice.

Objective To examine the utilization and cost of inpatient care and their influencing factors among the eld-erly in China from the view of social-ecology and to estimate the conditional and the unconditional cost,so as to provide refer-ence for allocating health resource efficiently among the elderly. Methods We build a social-ecological model( SEM) of the in-patient services utilization to estimate personal,familial and community circumstance factors of inpatient service utilizing a two-part model. Using joint modeling of likelihood and cost of inpatient care to estimate the parameter and predict the conditional and unconditional cost of inpatient. Data were extracted from Chinese longitudinal healthy longevity survey ( CLHLS) in 2011 on 8483 men more than 60 years old. Results The average cost of the elderly,24. 6% of whom actually utilize the services,is￥8082. 8. There are many reasons account for the utilization of inpatient care. In micro system,it was found that the elderly with chronic condition,having bad self-reported health and worse sleep quality have higher proportion of utilization and more cost of inpatient services. In mezzo system,the married men are more likely use inpatient services and spend more money curing disease than other groups. In macro system,the man who reside in the city or own more than one kind of social security have higher pro-portion and cost of inpatient care utilization. The predicted conditional and unconditional cost of inpatient service is ￥8397. 32,￥2478. 92,respectively. The male are higher than the female,theurban are higher than others. The elderly from 80 to 89 years old have the most expense in conditional predicted cost and 70~79 years old have most expense in unconditional predicted cost. Conclusion Social-ecological factors influence the behaviors of inpatient care utilization. Having chronic disease,self-reported health,sleep quality,marital status,residence and social security levels from different aspects are the primary factors which influ-ence proportion and expenditure of inpatient service utilization. The elderly with different characteristics have different conditional costs and unconditional costs,we should allocate health resources efficiently to promote the equity in health care utilization.
