BACKGROUND: Epidemiologic studies have shown an association between higher insulin levels and coronary artery disease, and metabolic studies have associated insulin resistance and compensatory hyperinsulinemia with non-insulin-dependent diabetes mellitus, hypertension, obesity,and lipid disorders.OBJECTIVE: To investigate the relationship between insulin resistance (IR) and erythrocyte insulin receptors (EIRs) in the patients with cerebral infarction (CI).DESIGN: Case-control trial.SETTING: Department of Neurology, China-Japan Union Hospital of Jilin University.PARTICIPANTS: From January 2004 to October 2004, 40 patients with CI, who were in-patients in China-Japan Union Hospital of Jilin University,were selected for the study. Meanwhile, 30 healthy doctors or nurses were recruited as normal controls.METHODS: The levels of blood glucose and serum insulin under fasting and 2-hour after oral glucose tolerance test (OGTT) were detected in the 40 patients with CI and 30 healthy doctors or nurses. Fasting blood glucose multiplied by fasting serum insulin was insulin resistance index (IRI). The number of insulin receptors and their binding affinity on every erythrocyte were determined using modified Gambhir's method. The correlation between the number of EIRs and IRI was analyzed.MAIN OUTCOME MEASURES: Comparison of CI group with controlRESULTS: Data of 40 patients with CI and 30 controls were analyzed, and under fasting and 2-hour after OGTT: The level of serum insulin under fasting and blood glucose, serum insulin at 2-hour after OGTT in CI group were higher than those in normal group [(13.30±5.15), (9.85±4.36) mU/L,(8.27±1.65), (6.32±1.37) mmol/L, (75.21±21.12), (28.26±6.31)mU/L,P ＜ 0.01,EIRs: The number of insulin receptors with high and low affinity and maximum specific binding rate in the patients with CI were significantly less than those in normal group [20.30±4.50, 23.80±4.10; 2 223.80±509.30,2 610.10±435.10; (10.62±3.55)%, (13.21±2.94)%, P ＜ 0.01]. Multiple linear regression analysis and correlation analysis showed the numbers of two types of EIRs in the patients with CI were negatively correlated with IRI (r=-0.458, -0.439, P ＜ 0.01, both).CONCLUSION: Insulin resistance can lead to cerebral infarction. Decrease in insulin receptors may play an importance role in cerebral infarction induced by insulin resistance.

BACKGROUND:Though the effects of conservative or traditional open reduction and internal fixation in the treatment of thoracolumbar fractures are reliable and satisfactory for most cases, two methods also have shortages. Minimal-invasive percutaneous pedicle screw system provides a new available method. OBJECTIVE:To investigate the clinical effect of Sextant percutaneous pedicle screw system in the treatment of thoracolumbar fractures. METHODS:A total of 55 patients, who had undergone percutaneous pedicle screw fixation using Sextant system (25 patients) or traditional open internal fixation (30 patients) for single-level vertebral body compression fractures in Department of Orthopedics of Renmin Hospital of Wuhan University from February 2011 to January 2013, were enrol ed in this study. RESULTS AND CONCLUSION:Except two patients in traditional open internal fixation group were lost after discharge, al other patients were fol owed up for 8-14 months. Operative time, intraoperative blood loss, postoperative drainage amount and hospital day were better in percutaneous pedicle screw fixation group than in the traditional open internal fixation group (P<0.05). Compared with preoperation, the sagittal Cobb angle, visual analogue scale and Oswestry disability index after operation were significantly lower (P<0.05), while anterior vertebral body height ratio was significantly higher in each group (P<0.05). No significant difference was found in terms of correction loss and Oswestry disability index between two groups at 8 months after operation (P>0.05). The results show that percutaneous pedicle screw fixation using Sextant system has a satisfactory outcome in the treatment of thoracolumbar fractures. However, obeying indication strictly is very important for clinical application.

Objective To investigate the correlation between helicobacter pylori infection and pathological characteristics of gastric mucosal in the elderly.Methods Retrospective analysis was conducted in 278 patients with benign upper gastrointestinal disease from January 2014 to June 2014.The patients were examined by endoscopy and 13C-UBT,and divided into elderly group (aged 60 years and over,n=111) and non-elderly group (aged＜60 years,n=167).The relationships between Hp infection and pathological changes in gastric mucosal tissue (severe chronic inflammation,neutrophil infiltration,lymph follicles,gastric gland atrophy,intestinal metaplasia) were analyzed.Results There was no significant difference in helicobacter pylori infection rate between the elderly group and non-elderly group [27.0％ (30/111) vs.36.5％ (61/167),P＞0.05].The rate of gastric gland atrophy was higher in elderly group than in non-elderly group [13.5％ (15/111) vs.6.0％ (10/167),P=0.028].The rates of severe chronic inflammation,neutrophil infiltration,lymph follicles,gland atrophy and intestinal metaplasia were 73.6％,70.3％,14.3％,18.7％,29.7％ in patients with helicobacter pylori infection,which were higher than those in patients without helicobacter pylori infection (19.8％,3.2％,0.5％,4.3％,8.6％,respectively,all P=0.000).Removing the factor of Hp infection,the rates of glands atrophy and intestinal metaplasia were higher in elderly group than in non-elderly group (8.6％ vs.0.9％,43.3％ vs.23.0％,P=0.013 and 0.045).Conclusions Helicobacter pylori infection correlates with severe chronic gastric mucosal inflammation,neutrophil infiltration,lymph follicles formation.Gland atrophy and intestinal metaplasia are related to the Hp infection,and age is also their influencing factor.

BACKGROUND:The effects of both conservative and traditional open reduction and internal fixation are dissatisfactory in the treatment of thoracolumbar fractures, however, minimal-invasive percutaneous pedicle screw-rod systems provide a new available method.
OBJECTIVE:To investigate the clinical effect of percutaneous pedicle screw fixation using Sextant minimal-invasive system in the treatment of thoracolumbar fractures.
METHODS:A total of 55 patients, who had undergone percutaneous pedicle screw fixation using Sextant system (25 patients) or open pedicle screw fixation (30 patients) for single-level vertebral body compression fractures in Department of Orthopedics, Renmin Hospital of Wuhan University from February 2011 to January 2013, were enrol ed in this study. They showed no neurological signs and symptoms. The operative time, intraoperablood loss, postoperative drainage amount, length of hospital stay, pre-and post-operative Cobb angle and anterior vertebral body height ratio were recorded and compared between two groups.
RESULTS AND CONCLUSION:Except two patients in open pedicle screw fixation group were lost after discharge, al other patients were fol owed up for 8-14 months. There were significant differences in operative time, intraoperative blood loss, postoperative drainage amount and length of hospital stay between two groups (P=0.000 0). The post-operative Cobb angle was significantly lower while anterior vertebral body height ratio was significantly higher at one week than those before fixation in two groups (P=0.000 0). No significant difference was found in correction loss between two groups at 8 months after operation. Experimental findings indicate that, percutaneous pedicle screw fixation using Sextant system has a satisfactory outcome in the treatment of thoracolumbar fractures. However, understanding the correct indications is very important for clinical application.

Objective To determine the prevalence and characteristics of the del(GJB6-D13S1830) in Connexin30(Cx30) gene in children with prelingual deafness.Methods Forty-six prelingual deaf children and 30 children with normal comprehension were obtained,and the del(GJB6-D13S1830)in the Cx30 gene were screened by polymerase chain reaction(PCR) in 2 groups.Results Three cases of 46 deaf children were found to have heterozygous del(GJB6-D13S1830) in Cx30 gene.The rest deaf children and the normal controls did not harbor this deletion.Conclusion The heterozygous del(GJB6-D13S1830) in Cx30 gene is one of causes of prelingual deafness.

Methods Collected the data of the 135 killing familiar homicides cases which have solved and happened in a province middle of China from 2011 to 2013. The paper analyzed the data accordding the basic information, the forensic professional, the forensic scene and so on. Results Most killing familiar cases occured between husband and wife or parents and children. The cases frequently occur in rural areas. Most of the cases occur between the adults. The killing familiar cases commonly occur in Decemember, January, Feburary, the cases commonly occur in evening(from 6 pm to 6 am). The motivate of the cases is unobvious, the murder suffer from the mental patient is commonly. In these cases, mostly tools of crime is the blunt tools and the sharp tools. Mechanical asphyxia and mechanical iniury were the most commonly causes of death in these cases. Conclusion The social characteristics of suspect, injury tool, cause of death, time of the incident in the killing familiar case showed similar general characteristics, but how collect evidence in the case is the difficulty of the case investigation.

The ubiquitin-proteasome system is composed by multiple enzymes which are ubiquitously expressed in mammalian cells and plays an essential role in a variety of biological processes. As key members of the protein degradation enzymatic system, the function of E3 ubiquitin ligases has been extensively investigated. BMP and TGF-? are critical molecules that regulate proliferation, differentiation and apoptosis of osteoblasts and chondrocytes through different signaling pathways. Resent findings indicate that the ubiquitin-proteasome system functions as a key regulator in bone cells and the E3 ligase mediates the proteolytic degradation of critical molecules in BMP and TGF-? signaling pathways. Recent progress on studies of HECT domain E3 ligase, Smurf, in osteoblasts and chondrocytes were summarized. The regulatory role of Smurf1 and Smurf2 in BMP and TGF-? signaling and osteoblast and chondrocyte function has been reviewed.
