The incidence and prevalence of type 1 diabetes in children and adolescents are increasing around the world,along with the suboptimal glucose control and higher incidence of long-term chronic complications during adulthood.Achieving good glycemic control and avoiding brain function damages induced by hypoglycemia are important when treating type 1 diabetes.Insulin lispro,a rapid-acting insulin used either alone or in combination with basal insulin analogue,can be effective,safety,and flexible.

Autoimmune disease is the result of interplay between genetic and environmental factors, Immunoregulatory genes and thyroid specific genes play important roles in the pathogenesis of autoimmune thyroid diseases.

Objective To evaluate the efficacy and safety of low energy intracardiac cardioversion in persistent atrial fibrillation. Methods Low energy intracardiac cardioversion was performed by delivering R wave synchronized biphasic shocks in 7 patients(4 men, 3 women) with persistent atrial fibrillation. Prior to the procedure, all patients underwent transesophageal echocardiographic examinations to rule out the presence of intracardiac thrombus and received subcutaneous injection of low molecular weight heparin for 3 5 days. Two custom made 6 Fr catheters(Rhythm Technologies of Getz, USA) were used for de fibrillation shock delivery. One catheter was positioned in the lower right atrium so that the majority of the catheter electrodes had firm contact with the right atrial free wall. The second catheter was placed randomly either in coronary sinus through right internal jugular vein or in the left pulmonary artery through femoral vein. In addition, a standard diagnostic 6 F quadropolar catheter was placed at the right ventricular apex for ventricular synchronization and postshock ventricular pacing. Shocks were delivered by Implant Support Device(Model 4510, Teleceronics). After conversion, all patients were treated with intravenous amiodarone in the first 24 hours followed by oral administration. Results In all 7 patients cardioversion of atrial fibrillation to sinus rhythm was successfully obtained. A mean of 2?1 shocks per patient has been delivered with a total amount of 13 shocks. The average delivered energy was 7.8?2.2 Joules. No complication occurred. At a mean follow up of 18?9 months, 4 of the 7 patients treated successfully showed sinus rhythm there after. Atrial fibrillation recurred in 3 patients at the second, fifth day and eighth month after cardioversion. Conclusions Low energy intracardiac cardioversion is effective and safe, and can be easily performed in patients without geneal anesthesia. It offers a new option for restoring sinus rhythm in patients with persistent atrial fibrillation.

Objective To know the advantages and disadvantages of problem-based learning from students'angle. Methods Interviewed 15 students by PBL scale and face to face interview,to know their ideas about problem-based learning,and then analyzed the results. Results PBL contributed to developing problem-solving skills,self-directed learning,team collaboration and extending professional knowl-edge. But it failed to show positive effect on students'learning motivation. Conclusions PBL has two sides on the outcomes of learning. Implementing PBL appropriately could gain the optimal effects.

Objective To explore the structure of self-developed "The Compliance Scale Among Kidney Transplantation Recipients" in order to provide effective tool to evaluate kidney transplantation recipients' compliance. Methods 886 follow-up kidney transplantation recipients of six organ transplantation centers in Shanghai were surveyed by "The Compliance Scale Among Kidney Transplantation Recipients". Results The exploratory factor analysis yielded a 25-item four-factor model termed medication compliance, life habits compliance, self-monitoring compliance, follow-up compliance. Conclusions The self-developed "The Compliance Scale Among Kidney Transplantation Recipients" could be a useful tool for evaluating compliance among kidney transplantation recipients.

Objective To investigate the efficiency and safety as well as the effect of chronic intravenous iron supplementation on the improvement of anemia in the patients with maintain hemodialysis (MHD). Methods Fifty-six patients with MHD were involved in the six-month, controlled trail and randomly divided into two groups: intravenous iron group (IV group) and oral iron group (oral group). The patients of IV group (n=28) were intravenously pumped 100 mg iron dextran during each hemodialysis session for the total amount of 1000 mg,after that,100 mg iron dextrin each two weeks. Patients in the oral group took 525 mg ferrous sulfate a day during the first three months and received iron dextran on the above methods under stopping oral iron supplement during the second three months. The efficacy was assessed by determining the change of hemoglobin (Hb), hematocrit (Hct), serum ferritin (SF) and transferring saturation (TSAT). Results The levels of Hb, Hct, SF, TSAT were increasing in the IV group after trail and there were evidently difference in those markers in the first three months, compared to the oral group, P

Objective To evaluate the variables which can be used as prognostic factors in predicting the outcome of Graves disease(GD)after treatment with antithyroid drugs.Methods We performed a retrospective audit of 204 patients with newly diagnosed Graves disease consecutively at the Ruijin Hospital.Results Overall,110 patients(53.9%)were considered to be treatment failures.Age at the time of diagnosis was(31.0±12.2)years in the successful group and(36.3±14.0)years in the failure group.Free T3(FT3)was(25.60±9.52)pmol/L and(19.16±6.38)pmol/L in the failure and the successful group(P=0.001).FT3 to FT4 ratio and thyrotrophin recptor antibody(TRAb)levels were higher in the failure group(P=0.001).Logistic regression analysis showed that thyroid size,FT3 to FT4 ratio and TRAb at the time of diagnosis were associated with failure outcome.The patients reached euthyroid state at 3,6,9 and 12 months respectively and in the failure group the patients with continued thyrotropin suppression were more than those in the successful group(P=0.001).Conclusions Graves disease patients with large thyroid size,high levels of TRAb and FT3 to FT4 ratio before drug treatment are more likely to fail to respond to antithyroid drug treatment.We also found that patients with continuing thyrotropin suppression and attainmen of euthyroid state in the course of treatment had low remission rate and prolonged therapy.

Objective To explore the mechanism of persistent thyrotropin suppression in euthyroid patients with Graves′ disease after antithyroid drugs (ATD) treatment. Methods A prospective clinical study was performed in 122 patients with newly diagnosed Graves′ disease. All the patients were treated with 30 mg methimazole or 300 mg propylthiouracil daily, to whom L-T4was added, aiming at normalizing FT3 and FT4 but avoiding elevated TSH level. When the patients were clinically and biochemically euthyroid for at least 3 months, their blood levels of thyroid hormones, TSH, TSH receptor antibody(TRAb) and thyroid peroxidase antibody(TPOAb) were detected again and the cases were divided into two groups according to negative or positive TRAb. Results After treatment as long as (7.1±1.1) months, stable euthyroid status was restored for 3 months. When the patients reached the euthyroid state, 64 of them still had detectable TRAb levels, and 58 became negative TRAb. The two groups had similar levels of FT3 and FT4, but patients with positive TRAb had lower TSH level than patients with negative TRAb[0.044 mIU/L(0.001-4.163 mIU/L) vs 1.749 mIU/L(0.079-4.646 mIU/L),P＜0.01]. In addition, the TSH level was negatively correlated with TRAb level (r=-0.539, P＜0.01), and not with FT3, FT4 levels or other factors. Conclusion The present study showed that elevated TRAb level is associated with persistent suppression of TSH in patients with Graves′ disease after being rendered euthyroid. This finding may be due to the binding of TRAb to pituitary TSH receptor.

Objective To investigate the clinical and genetic characteristics in two patients with androgen insensitivity syndrome. Methods Clinical features and laboratory data were collected from the patients and their families. All exons of the androgen receptor gene were amplified by PCR and PCR products were sequenced. Results Patient 1 presented with unambiguous female external genitalia, unilateral gynecomastia and primary amenorrhea. He did not have axillary hairs or pubic hairs. Patient 2 presented with undervirilization including scanty body hairs, gynecomastia and hypospadias. A missense mutation of

Objective To study the genotype of the thyroid hormone receptor ? (THRB) gene in a patient with thyroid hormone resistance syndrome. Methods The peripheral blood samples of the patient and his parents were collected, then DNA was isolated. PCR and direct sequencing techniques were performed to determine if there were mutations in their THRB gene. Results No mutation was found in exon 1-9. There was a point mutation in exon 10 of THRB which is a T to C transition in nucleotide 1658 resulting in the replacement of the normal Val (GTG) with an Ala (GCG) (V458A). The mutation was located in exon 10 of THRB gene and was a heterozygote. No mutation was found in THRB gene of his parents.Conclusion The gene diagnosis confirms that the patient has a mutation V458A located in the ligand binding area of THRB.
