Hypoglycemia is a common metabolic problem in newborn infants,which might lead to brain injury even brain death when it keeps extremely low for a long time.Therefore,it is of great importance to monitor blood glucose in neonates,especially in groups of infants who are at risk of hypoglycemia,in order to identify and treat this condition and prevent adverse neurological outcomes promptly.It is given that infant of a diabetic mother,preterm neonate,low birth weight and asphyxia are its risk factors.Relative to blood glucose monitoring methods in clinical,continuous glucose monitoring system is comprehensive,continuous and with low pain.Continuous glucose monitoring system has been applied in high-risk neonates of hypoglycemia in recent years.It is of great help to understand the complete picture and change trend of blood glucose,optimize blood glucose management,study newborn glucose metabolic characteristics and the relationship between hypoglycemia and brain damage,so as to define and manage neonatal hypoglycemia.

Objective: To analyze the correlation between single nucleotide polymorphisms (SNP) of solute carrier family 22 member4 (SLC22A4) and runt-related transcription factor 1 (RUNX1) gene with rheumatoid arthritis (RA) and ankylosing spondylitis(AS) in Chinese Han ethnicity. Methods: Case-control studies were conducted with an RA cohort (104 RA patients and 109 healthy subjects) and an AS cohort (278 AS patients and 417 healthy controls). Three SNPs of SLC22A4 gene and an SNP of RUNX1 gene were genotyped by direct sequencing; we also assessed whether these alleles and genotypes were associated with RA and AS. Results: No significant differences in the distribution of the alleles and genotypes of SLC22A4 and RUNX1 polymorphisms were found between patients with RA and AS and healthy controls. Conclusion: Our results suggest that SLC22A4 and RUNX1 polymorphisms analyzed in the present study are not the susceptible genes for RA and AS in Chinese Han ethnicity.

BACKGROUND:The bioceramics has the ideal pore size, high porosity and the through-hole rate, can provide the ideal physiological activity space for the bone cel repair, and can obviously improve bone conduction. OBJECTIVE:To explore the bone conduction and bone induction in the repair of bone defects in the stage of bone defect of bionic biphasic ceramic bioactive bone. METHODS:A total of 20 New Zealand white rabbits were randomly divided into bioactive glass and biomimetic biphasic ceramic bioactive bone groups, and were used to construct the animal bone damage model. They were given the repair with bioactive glass and biomimetic biphasic ceramic bioactive bone. RESULTS AND CONCLUSION:At 4 weeks after model establishment, scanning electron microscopy demonstrated that dense periosteal tissue was observed in the biomimetic biphasic ceramic bioactive bone group. At 8 weeks, dense combination was found, and no obvious fissure existed. At 12 weeks, complete bone demarcation blurred, showing a natural transition. Moreover, the binding site was very dense. There were a large number of new bone tissues, bone trabecula was regular and connected to a piece. The bone material has been largely degraded. Bone defects were repaired completely. The bone density was close to normal bone. At 8 weeks, in the bioactive glass group, the binding site presented obvious fissure. At 12 weeks, the fissure had been connected, but the binding was not tight as compared with the bionic biphasic ceramic biologic active bone group. The bone defect got preliminary repair. A smal number of new bone formed trabecular bone, but could not connect or traverse. There was no recanalization of the marrow cavity. A few continuous bone cal us traversed the broken end. These data demonstrate that bionic biphasic ceramic bioactive bone has good bone conduction, bone induction and biocompatibility in the repair of segmental bone defects.

Objective To evaluate the method, clinical effects and influential factors of using three dimensional external fixators in the treatment of severe open comminuted tibiofibular fractures 5 cm near the knee or ankle joints. Methods We retrospectively analyzed 32 cases of open comminuted tibiofibular fracture 5 cm near the knee (11 cases) or ankle joints (21 cases). They were treated with three dimensional external fixators from October 2000 to May 2005. The patients with small wounds were treated with manipulative reduction or leverage reduction through the wound under the guidance of C-arm radiography. In case of malreduction or soft tissue being tangled by the fracture ends, visible reduction was carried out after the wound was lengthened or a small incision was added. Limited internal fixation was used in case of necessity. The results were evaluated in terms of shortening of the fractured limbs, X-ray manifestation, bilateral flexion differences and postoperative walking complaints. Results Follow-ups from 5 to 18 months (nine months on average) showed that all the cases achieved osseous union. The mean union time was 5.6 months. The total excellent and good rates of fracture healing and functional recovery were 81.3% and 87.5% respectively. Conclusion Application of the three dimensional external fixator is appropriate for the treatment of severe open comminuted tibiofibular fracture 5 cm near the knee or ankle joints, because its operative procedure is simple, the injury it causes is minimal, its fixation is reliable and its complications are quite limited.

Objective To investigate the current situation of occupational burnout of doctors in west China and to explore the relationships among burnout,social support and work-family conflicts.Methods 611 doctors in west China were assessed by Chinese Maslach burnout inventory( CMBI),social support rating scale(SSRS) and work-interference-with-family and family-interference-with-work questionnaire.Results 14.1％ of the doctors in west China got high scores on emotional exhaustion(EE),49.4％ of them high scores on depersonalization(DP) and 33.1％ high scores on reduced personal accomplishment (RPA) ; 27.3％ experienced mild burnout,43.7％ moderate burnout and 3.3％ severe burnout.Doctors who had worked for 5 ～ 10 years and those for 11 ～ 20 years experienced greater EE.Those doctors with bachelor or master degree and intermediate or senior titles got highest level of depersonalization.Doctors in second-class hospitals got highest scores of depersonalization,and those who worked in first-class hospital experienced the highest sense of achievement.Logistic regression analysis showed that social support was a protective factor for burnout,but the conflict between work and family was a risk factor.Conclusion The status of occupational burnout among the doctors in west China is in a grave condition,the balance between family and work,and social supporting is crucial for doctors to resist the occupational burnout.

Objective:To investigate the influence of preoperative biliary drainage (PBD) on morbidity of severely obstructive jaundice patients after pancreaticoduodenectomy (PD).Methods:A total of 98 severely obstructive jaundice(Serum total bilirubin＞300 μ mool/L) patients underwent PD between February 2010 and October 2015 were enrolled in the study.The patients were divided into two groups based on undergoing PBD or not.The no-PBD group comprised 52 patients and the PBD group comprised another 46 patients.Perioperatives parameters,including operative time,intraoperative blood loss,postoperative mortality and morbidity and postoperative hospital stay were compared between the two groups.Results:The demographics,preoperative examinations and pathological results were similar between the two groups (P＞0.05).Operative time of the no-PBD group was statistically longer than the PBD group (379.44 ± 88.57min vs 346.98 ± 57.17 min,P＜0.05).Besides,intraoperative blood loss of the no-PBD group were much more than the PBD group (365.00 ± 187.07mL vs 297.83 ± 139.57 mL,P＜0.05).There was no statistical difference of mortality rate between the no-PBD group and the PBD group(3.85％ vs 2.17％,P＞0.05).The overall morbidity rate of the 2 groups were similar (53.85％ vs 43.48％,P＞0.05),but the pancreatic fistula rate of no-PBD group was significantly higher than the PBD group (30.77％ vs 13.04％,P＜0.05).Conclusion:PBD could reduce operative time,intraoperative blood loss and pancreatic fistula rate after PD.Meanwhile,the mortality and overall morbidity rates were similar between the two groups.PBD should be considered for severely obstructive jaundice patients.

To research the association between primary progressive pterygium and tear film.
●METHODS: Totally 60 cases of primary progressive pterygium from September 2012 to June 2013 in our hospital were enrolled. The pterygium eye was for observation group and the contralateral eye as the control group. The differences of eye symptoms, tear film break-up time ( BUT ), Schirmer Ⅰ test ( S Ⅰ t ), corneal fluorescein staining (FL), tear ferning test (TFT) and the conjunctival impression cytology ( ClC) were compared between two groups.
●RESULTS: The eyes in observation group had higher symptoms score, FL score, grades of conjunctival squamous metaplasia, percentage of abnormal tear ferning, but had lower BUT and density of goblet cell, the differences had statistically significance (P<0. 05); Similar S Ⅰ t results were presented in the two groups, the difference had no statistically significance (P>0. 05).
● CONCLUSlON: Primary progressive pterygium can cause a decrease in tear film stability, which in turn lead to some dry eye symptoms such as dry feeling and burning sensation, and its mechanism may be caused by multi-factors, such as density change of goblet cell and the tear fluid dynamics.
