Thyroid hormones (TH) play an imp or tant role in the development and maturity of the mammalian brain. Maternal TH de ficiency, even subclinical hypothyroidism, leads to poor neurodevelopment of the fetus. Screening of pregnant women for hypothyroidism is recommended. Identific ation of the TH-responsive genes in the developing brain and investigation on t heir functions are helpful to provide insights into the molecular mechanisms by which TH influence brain development.

Objective To evaluate the clinical value of dual-energy subtraction digital radiography in diagnosing the pulmonary nodulesand calification in nodules.Methods Using American GE Revolutln DR-XR systems,All 80 patients were examined by dual-energy.Tissus images、bone images and the original digital radiographic images were obtained.Dual-energy digital subtraction images were compared with the original digital radiographic images.Results Of 186 pulmonary nodules proved by CT,126(94 uncalified and 32 calified)were detected by tissues images and bone images and 109(83 uncalified and 26 calified)were detected by the original digital radiographic images.Conclusion Dual-energy subtraction imaging is superior to the original digital radiographic images in detection of pulmonary nodules and calification in a nodule.Dual-energy subtraction images can act as a complement for the original digital radiographic images.

Objective To investigate the correlation between the glycosylated hemoglobin (HbA1c) detection data and hemo‐rheological indicators in diabetes patients to provide reference basis for its treatment and prevention .Methods One hundred and forty‐two patients with typeⅡdiabetes mellitus(T2DM ) in the hospital were selected as the research subjects and divided into the A group(69 cases ,better control) and B group(73 cases ,poor control) according to the HbA1c detection results .Contemporaneous 70 healthy individuals undergoing physical examination were selected as the control (C group) .The detection results of HbA1c ,hemo‐rheology and biochemical indexes were performed the contrastive analysis .Results Except hematocrit and erythrocyte deformation index without statistical difference among 3 groups(P>0 .05) ,the other hemorheologic indicators had statistical differences among 3 groups(P<0 .05) .No matter the HbA1c level in T2DM patients ,the hemorheological indexes ,triglyceride and total cholesterol were higher than those in the healthy people ,When the HbA1c leve was poorly controlled ,the increase degresss of various indexes were more significant .Conclusion The abnormality of hemorheology indices exist in most of the patients with diabetes mellitus .It is recommended that clinic should monitor the HbA1c level for long term and strictly observe the change of hemorheology indexes to guide the clinical treatment for reaching the effects of early vascular protection and prevention of diabetic complications .

Objective To investigate the clinical features and prognosis of elderly patients with acute panereatitis.Methods One hundred and twelve elderly patients with acute pancreatitis were included in our study.The clinical features and prognosis were compared with those of the 120 non -aged patients with acute pancreatitis during the same period.Results Cholecystolithiasis was the most common etiology of acute pancreatitis in both groups[81 cases(66.3%) in aged group,70 cases (58.3%) in non-aged group].Abdominal pain was the most common symptom in both groups, followed by fever.Two elderly cases were diagnosed only by autopsy because of mild abdominal pain and rapidly attack of shock.There were 31 cases with severe pancreatitis in aged group and 14 in non -aged group (P

Medical postgraduates are the future core force of clinical diagnosis and treatment,scientific research,education and sanitary administration.Therefore,to cultivate qualified professionals,the key of contemporary medical postgraduate education is to pay more attention to comprehensive quality training in order to make students adapt to the continuous development of society and medical model.The First Clinical College in Wuhan University has implemented the hospital administration internship in combination with social needs and explored the education model of contemporary medical students with comprehensive quality.

We surveyed the graduate students at Peking University Health Science Center for the difficulties during their study. The result showed that the major difficulties were job pressure, completing studies and economic burden. Some students were also bothered by love affairs, health conditions and interpersonal relationship. Suggestions were made for future work to help these students to cope with such difficulties to complete their study smoothly.

Objective To analyze the main clinical manifestations of intestinal lipoma and discuss the treatment of intestinal lipoma.Methods The clinical data of 19 patients with intestinal lipoma treated in our hospital in recent 15 years were analyzed retrospectively.CT,ultrasonography,and colonoscopy were used in diagnosis.Local intestinal resection by laparoscopy and laparotomy were employde.Results Intestinal lipoma presented with a variety of symptoms including intestinal bleeding,abdominal pain,anemia,intussusception,and bowel obstruction.In 17 of the intestinal lipoma patients,the main clinical manifestations were change of bowel habits,abdominal pain and bloody stool;13 of them had intestinal intussusception or obstruction,and two patients were asymptomatic.Sixteen patients underwent colonoscopy,and seven of them were correctly diagnosed.Seventeen patients received surgical resection and recovered.The diameter of mass was 3-6.5 cm.The pathologic exam showed submucosal lipoma in 12 cases,two cases showed ulcer formation with erosion,2 cases had intermural lipoma and one case had atypical lipoma with potential malignant transformation.Two asymptomatic patients diagnosed by colonoscopic biopsy werre only followed up at regular intervals.Conclusions Imaging diagnosis and colonoscopy are helpful in the preoperative diagnosis of intestinal lipoma.The method of treatment is based on the size of the tumor and presence or absence of pedicle.Endoscopic electrosection is often used for tumor mass less than 3 cm in diameter,otherwise local intestinal resection is the treatment of chocie.

Objective To investigate the clinical significance in monitoring the dynamic oxygenated parameters in full-term neonates with acute respiratory distress syndrome (ARDS) and its relationship with the prognosis. Methods Forty-one full-term neonates with ARDS from 3 hospitals were divided into two groups according to the clinical outcomes: the death group (n=17) and the survival group (n=24). The parameters of breathing machine and arterial blood gas analysis in these two groups at 2 h, 12 h, 24 h and 36 h after mechanical ventilation were analyzed retrospectively. PaO_2/FiO_2, A-aDO_2, PaO_2/P_AO_2 and RI were calculated and compared between the two groups and within each group among the values of different period. Results Under the circumstance that parameters of breathing machine in the death group were obviously or gradually higher than those in the survival group, PaO_2 in the death group [(10.38?1.45)kPa] was lower than that in the survival group [(11.42?0.98)kPa] only at 36 h (P0.05). In the death group, PaO_2/FiO_2 at 24 h and 36 h [(15.86?4.92)kPa and (15.99?5.62)kPa] was lower than that in the survival group [(21.18?6.48)kPa and (27.12?8.33)kPa](P0.05) . Conclusions PaO2is not a sensitive indicator on the prognosisof NRDSinits early stage . PaO2/Fi O2, A-aDO2, PaO2/PAO2and RI are better than PaO2to reflectthe degree of lung injury ,oxygen exchange rate and therapeutic efficacy . A-aDO2and PaO2/PAO2arevery sensitive in assessing the therapeutic effect and the dynamic monitoring may be helpful injudgingthe prognosis .

This paper introduces the nursing care for 36 patients with framework exposure in auricular reconstruction by temporal superficial fascia flaps combining with split skin grafts transplantation,such as pre-and post-operative behavioral in-struction,psychological care,and close observation of blood circulation of reconstructed auricular. The patients' wounds healed up well and all the split skin grafts survived successfully. No infection and stent exposure occurred once more. The appear-ance of the reconstructed auricular was pleasing too. It is suggested that high quality of pre-and post-operative nursing,care-ful health education and psychological care be beneficial for the successful repair of framework exposure after auricular recon-struction.
