Objective To investigate the clinical significance of monitoring blood glucose in term infants with asphyxia. Methods The blood glucouse within 24 hours of admission and prognosis were retrospectively analyzed in full-term neonates with asphyxia admitted from January, 2011 to December, 2012. Results Among 256 term infants with asphyxia, 95 cases (37.11%) had abnormal blood glucose, 63 cases (24.61%) were hypoglycemia and 32 (12.50%) were hyperglycemia. The incidence of mild asphyxia and severe asphyxia, the number of damaged organ were significantly different among infants with hypoglycemia, normal blood glucose, and hyperglycemia (all P<0.001). Among 256 term infants, 206 cases were mild asphyxia, 50 cases were serve asphyxia. The incidence of abnormal blood glucose and hyperglycemia were significantly higher in infants with serve asphyxia than those in infants with mild asphyxia (P<0.01). Among 256 term infants, 227 cases (88.67%) had organ damaged. 96 cases involved one organ, 72 cases involved two organs, and 59 cases involved three or more organs. The incidence of abnormal blood glucose, hypoglycemia, hyperglucemia were significantly different among infants invoved one, two or threr and more organs. The incidence of hyperglycemia was the highest in infants with three or more organ damaged, and the incidence of hypoglycemia was the highest in infants with two organ damaged. Conclusions The term infants with severe asphyxia and more organ damaged were prone to with abnormal blood glucose.

Objective To explore the significance of serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) for the death risk evaluation in elderly patients with chronic disease in five years.Methods A total of 765 elderly patients with chronic disease[136 patients with coronary heart disease (CHD),76 patients with hypertension disease (HD),86 patients with chronic obstructive pulmonary disease (COPD),75 patients with Type 2 diabetic mellitus (T2DM),76 patients with cerebral infarction (CI),73 patients with coronary heart disease combined with hypertension,71 patients with coronary heart disease combined with chronic obstructive pulmonary disease,61 patients with coronary heart disease combined with diabetic,51 patients with coronary heart disease combined with cerebral infarction,and 60 patients with three comorbidity] were classified into the survival group (312 cases) and the death group (453 cases) according to disease prognosis.The serum NT-proBNP levels of 88 healthy controls and 765 elderly patients with chronic disease were determined by bi-directional lateral flow immunoassay.The death events were followed up and observed for an average of 5 years.The results were analyzed statistically.Results The serum NT-proBNP levels in the death group with various diseases were significantly higher than the survival group (P ＜0.01),the patient's age and the proportion of male in the death group and the survival group had no significant difference (P ＞ 0.05).The serum NT-proBNP levels,the patient's age and the Proportion of male in the death group with various elderly chronic diseases had no statistical significance (P ＞ 0.05).The serum NT-proBNP levels in the death group with various elderly chronic diseases had no statistical significance (P ＞ 0.05),and were significantly higher than the survival group (P ＜ 0.01).The patient's age and the proportion of male in the death group and the survival group had no significant difference (P ＞ 0.05).The serum NT-proBNP levels in the death group in the different periods had statistical significance (P ＜ 0.01),and were significantly higher than the survival group and healthy control group (P ＜ 0.01).The more shorter of the survival time was,the higher the serum NT-proBNP 1eve was.The serum NT-proBNP levels were negatively correlated with the survival time of the patients (r =-0.378,P =0.000).The receiver operator characteristic (ROC) curve indicated that the optimal cut-off values of serum NT-proBNP levels for the death risk evaluation in elder patients with chronic disease were 1 499.50 ng/L.Kaplan-Meier survival curve showed that the survival rates of serum NT-proBNP levels had significant difference (P ＜0.01).The higher the serum NT-proBNP level was,the more shorter of the Survival rates were.Conclusions The levels of serum NT-proBNP have an important prognostic value in the death risk evaluation in elderly patients with various chronic disease.It is an independent risk factor for the death occurred in eiderly patients with chronic disease.The levels of serum NT-proBNP are closely correlated with the survival rates and survival time of elderly patients,It can be used as a monitoring indicator of the elderly patients with chronic disease in risk stratification.

OBJECTIVEThis research aimed to analyze the three-dimensional position of mandibular canal (MC) and man of MC and its relationship with the surrounding structures dibular morphology of normal young males and females by using data from cone beam computed tomography (CBCT), as well as to provide an anatomical basis for clinical surgery of the mandible.

METHODSNormal occlusion and CBCT scans of 29 normal young people were conducted. InVivo 5 software was used to reconstruct the mandible, anchor the points, and measure the jaw shape and three-dimensional course of MC. All measurements were analyzed with SSPS 17.0 software.

RESULTSThe MC lingual bone cortex was thinner than the MC buccal bone cortex, and the distance of the MC to the buccal bone cortex gradually increased. However, the distance of the MC to the tongue bone cortex and alveolar crest gradually decreased from proximal to distal. In addition, the distance of the MC to the mandibular lower margin was minimal at the first molar and reached the maximum at the second premolar. No significant difference was observed among the heights, widths, and thicknesses of the left and right sides of the cortical bone of the mandibular body cross sections. From the midline to the farthest point, the height and lower one-third thickness of the lingual cortical bone of the mandibular body cross sections gradually decreased, whereas the width of the upper cross section and upper one-third thickness of the buccal cortical bone gradually increased. Significant difference was observed in some measured values.

CONCLUSIONAfter MC enter into the mandibular foramen, it moved away from the lingual to the buccal bone but gradually returned to the lingual bone; its general course is closer to the lingual bone. The mandibles of males are thicker than those of females. CBCT can accurately display the course of MC and its relationship with the surrounding structures.

Objective To investigate the relationship of single nucleotide polymorphism (SNP) on FTO gene rs9939609 with metabolism index and obesity in children. Methods One hundred and fifty-three children (age 7-11 year) were recruited in this study, 102 of them were obese and 51 of them were overweight. One hundred and sixty children with normal body weight were recruited as control. Height, weight and biochemical indicator of liver function were measured. PCR and direct sequence were applied to detect the polymorphism of rs9939609, and the frequency of the allele was calculated. Results TT or TA/AA genotype frequency on FTOgene rs9939609 was significantly different among overweight group, obesity group and normal con-trol group (χ2=23.01, P<0.001);TA/AA genotype frequency in overweight and obesity group was significant higher than that in the control group(P<0.014). The frequencies of T and A allele in overweight group, obesity group and control group was 96.25%and 3.75%, 85.29%and 14.71%, 85.78%and 14.22%respectively. There was significant difference of allelic frequency among overweight group, obesity group and control group (χ2=21.72, P<0.001). The frequency of A allele in overweight and obe-sity group was higher than that in control group (P'<0.014). Subjects with TA/AA allele had significantly higher BMI compared with subjects with TT allele. Conclusions rs9939609 of FTO gene is associated with obesity in children, and allele A on this spot may raise BMI and leads to overweight and obesity.

OBJECTIVETo investigate the application of osteotomy template manufactured via 3D printing technique in bilateral sagittal split osteotomy (BSSO).

METHODSThe patient group consisted of 32 patients (17 males and 15 females) with mandibular hypoplasia who underwent a BSSO setback (Hunsuck modification; 64 splits). The mean age at the time of surgery was 23.5 years (range 1.9-35 years). All patients were scanned using cone beam computed tomography (CBCT) to create a 3D model of the mandibular, and the osteotomy template of the inner horizontal ramus of mandible bone incision was manufactured via 3D printing technique. All splits underwent operation with or without the osteotomy template by either a young doctor (attending doctor) or a doctor with extensive orthognathic surgery experience (chief doctor). The time it took to perform the mandible bone incision of the inner horizontal ramus of each group was recorded. Postoperative CBCT scan was performed, and the lingual split scale was used to assess the effect of the operation.

RESULTSPrimary healing of incisions was observed in all patients, and no serious complications occurred. The time it took to perform the mandible bone incision of the inner horizontal ramus was significantly different in the four groups (F=30.059, P<0.05), and it was longer in the group of the attending doctor without osteotomy template than in the other three groups (P<0.05). No significant difference was observed in the other groups (P>0.05). Although all splits (n=64) were performed according to the standardized protocol, only 59.38% (38/64) of the fracture lines run according to the Hunsuck's description. By contrast, only 21.88% (14/64) run through the mandibular canal and 18.75% (12/64) was split. The database was analyzed using crosstabs and via Fisher exact test. The split pattern was influenced by the application of an osteotomy template (P<0.05).

CONCLUSIONThe application of osteotomy template manufactured via 3D printing technique in BSSO was effective, which enabled the young doctor to complete the operation faster and with good results.

Objective To report the clinical characteristics of prosthetic valve endocarditis (PVE).Methods All 25 cases of definite PVE (Duke criteria) diagnosed at our hospital between January 1992 to December 2008 were retrospectively analyzed. Among them, 7 cases were pathologically confirmed and the others were clinically confirmed with either 2 major criteria or 1 major and ≥3 minor criteria. Their clinical characteristics, underlying heart diseases, previous heart operations, presenting manifestations, causative microbes, echocardiographic findings and prognosis, were studied. Results (1) Although most cases underwent valve transplantations for underlying heart diseases of rheumatic heart diseases and congenital heart diseases, 10 patients were complicated with infectious endocarditis (IE) prior to the operations, 4 of them were PVE. (2) Eleven of them developed PVE within 2 months postoperatively. Fever (100%),major vessel embolism (48%), and anemia (36%) were the most frequently manifestations. Fourteen cases (56%) had positive culture results with 15 causative pathogens, including 5 coagulase-negative Staphylococcus (CNS, 3 were methicillin-resistant coagulase-negative Staphylococcus, MRSCoN), 4 fungi, 2Enterococcus faecalis, 2 Burkholderia cepacia, 1 Stenotrophomonasmal-tophilia, and 1 Streptococcus.(3)Prosthetic valve vegetations, periannular leakage, regurgitation, were the main echocardiographic findings.Transesophageal echocardiography (TEE) revealed 13 PVE who had no positive findings on previous transthoracic echocardiography (TTE). (4) Eighteen PVE (72%) developed peri-annular complications (12 leakage, 3 dehiscence, 2 abscesses, 1 fistula), major vessel embolism, congestive heart failure (16%) were frequently observed, 9 of the 17 patients died in hospital, in spite of intensive managements.Conclusions PVE has a high mortality and is a severe complication for patients who underwent heart surgery. Its causative pathogen spectrum is quite different from that of native valve endocarditis. TTE is not sensitive for some PVE cases.
