Objective To investigate the association of impaired glucose regulation and adiponectin (APN)with the clinical severity of coronary lesions.Methods A total of 210 cases of suspected coronary heart disease were examined by coronary artery angiography.The patients were differentiated as 4 groups:42 patients with normal glucose tolerance (NGT),36 patients with impaired fasting glucose(IFG),92 patients with impaired glucose tolerance (IGT;including 44 cases with postpraudial 2h plasma glucose(2 hPG) ＜ 10 mmol/L as IGT1 subgroup and 48 cases with 2h PG ≥ 10 mmol/L as IGT2 subgroup),and 40 patients with combination of IFG and IGT.Accordingly,body mass index (BMI),blood pressure,blood lipid,insulin,APN and CRP were measured to evaluate by Gensini score.Results The incidence of coronary heart disease and Gensini scores in IGT and IGT+IFG groups were significantly higher than those in either IFG or NGT subset(P＜0.05).APN in both IGT and IGT+IFG subsets was significantly lower than that in IFG or NGT subsets(P＜0.05),CRP values were significantly raised in both IGT and IGT+IFG subgroups compared with the other 2 subgroups(P＜0.05).Statistical difference in Gensini scores and APN was found between the 2 IGT subgroups (P＜0.05).Gensini scores were negatively correlated with APN level.Multivariate regression analysis showed that both APN and HOMA-IR values were independently correlated with the Gensini scores.Conclusion The lowered APN may serve as a more sensitive factor in predicting the coronary lesions in patients with IGR,especially in IGT cases.It woula be beneficial to cardiovascular complication by controlling the postprandial blood glucose level below 10 mmol/L.

Objective To investigate the influences of pain on early neonatal neurobehavioral development Methods 65 newborn infants admitted to the Neonatal Intensive Care Unit( NICU )of our hospital from October,2009 to March,2010 were randomly chosen as the objects of this study.In light of Neonatal Behavioral Neurological Assessment( NBNA) revised by Professor Bao Xiulan,examinations were carried out before and after pain stimulation,and a statistical analysis of the results of the examinations was conducted.Results The total scores of NBNA before and after the pain stimulation were (36.49±1.73) vs.(34.80±1.79) respectively,demonstrating a significant difference.Specifically,after the pain stimulation,the scores of behavioral ability and active muscle tension decreased,with a very significant difference.However,there was no significant difference in terms of the scores of passive muscle tone,primitive reflexes and common reactions.Conclusions Neonatal pain exerts influences on early neurobehavioral development,particularly on behavioral ability and active muscle tension.The training of neonatal health care professionals in the management of and the intervention in neonatal pain should be strengthened in order to decrease the adverse effects of pain on neonates.

Objective To investigate the influencing factors of pain and the changes of vital signs in newborn infants. Methods Forty two newborn infants were rated by the behavioral scale of acute pain in newborn infants. The scores of pain were compared among infants with different gender,gestational age,birth weight,birth age,type of puncture and whether by vaginal birth or not. At the same time,the respiration rate,heart rate,blood pressure and oxygen saturation (SO2)were dynami-cally recorded by the multi-function monitor in the process of puncture. Results The average score of pain was 7.6. There was no significant difference among newborn infants with different gender,gestational age,birth weight and type of puncture(P> 0.05),while significant differences among infants with different birth age and whether by vaginal birth or not (P=0.015 and 0.043 respectively). In the process of puncture,the SO2 was significantly decreased,while the respiration rate,heart rate,sys-tolic and diastolic blood pressure were significantly increased. Conclusions Pain is prevalent in newborn infants and accom-panied by obvious changes of vital signs. The means of childbirth and birth age have significant influence on the neonatal pain. It is suggested to pay close attention to the neonatal pain and take effective interventions.

Objective To investigate whether cerebral microbleeds (CMBs) can predict hematoma expansion in hypertensive cerebral hemorrhage bleeding.Methods One hundred and forty-four patients with hypertensive cerebral hemorrhage bleeding in 6 hours after the onset of symptom were included.Gradient echo pulse sequence-T2 WI (GRE-T2 WI) and computed tomography (CT) were performed to detect the size of hematoma in half an hour after hospital admission.Based on the performance of GRE-T2 WI,patients were divided into microbleeds group and no microbleeds group.CT was performed 24 and 72 hours later to check whether hematoma was enlarged,the ratio of hematoma enlargement and the increased hematoma volume were compared between 2 groups.Results A variable number of CMBs were found in 74 cases by GRE-T2WI on admission.The hematoma volume was increased in 12.5％ (18/144) of patients by CT 24 hours later,and in 13.9％ (20/144) by CT 72 hours later.The ratio of CMBs in microbleeds group was higher than no microbleeds group significantly (70.0％ (14/20) vs 48.4％ (60/124),x2 =4.221,P ＜0.01).Besides,the ratio of the patients with the increased hematoma volume in microbleeds group was significantly higher than no microbleeds group(17.6％ (13/74) vs 10.0％ (7/70),x2 =3.172,P ＜ 0.05).Logistic multiple regression showed that CMBs was the only risk factor which could enter regression equation (OR=2.213,95％CI 1.320-2.972,P＜0.01).Conclusion CMBs patients with hypertensive cerebral hemorrhage bleeding in GRE-T2WI can predict the high risk of hematoma expansion.

Objective To explore the relationship between histological chorioamnionitis(HC),fetal vasculitis(FV)and the morbidity of neonatal respiratory distress syndrome(RDS).Methods Three hundred and forty-seven cases of infants at the gestational ages of 28 +0 to 31 +6 weeks who were admitted to the Neo-natology Department of our hospital from October 2009 to June 2013 were analyzed retrospectively.They were divided into four groups according to the occurrence of HC and FV,namely,HC positive group and HC negative group,FV positive group and FV negative group.The patients in the HC positive group were further divided into FV positive group and FV negative group according to the occurrence of FV.The morbidity of RDS among above-mentioned groups was compared.Results The clinical characteristics including propor-tion of male,gestational age,birth weight,cesarean delivery,antenatal corticosteroid use,gestational hyperten-sion,gestational diabetes and cholestasis of pregnancy showed no statistically significant difference among all the groups(P 〉0.05).The incidence of RDS in the HC positive group(145 cases)was 49.6%(72 cases), which was significantly lower than that in the HC negative group(67.3%,126 /202,P 〈0.05).The incidence of RDS in FV positive group(64 cases)was 42.2%(27 cases),which was significantly lower than that in FV negative group(63.3%,179 /283,P 〈0.05)In the HC positive group(145 cases),the incidence of RDS in FV positive group (64 cases)was 42.2% (27 cases),and 55.6% (45 cases)in FV negative group (81 cases),which showed no significant difference(P ﹦0.01 ).Conclusion (1 )HC or FV can reduce the incidence rate of RDS in premature infants.(2)HC combined FV cannot furtherly reduce the incidence of RDS.

OBJECTIVE: To study the results of TEOAE and AABR hearing screening and follow-up in NICU. METHOD: Total 574 cases in NICU were included in this study, all cases received both TEOAE and AABR hearing screening while admission and rescreening when one-month-old. The cases that were abnormal on either test in rescreening were asked to return for diagnostic tests at 3 moths old. The patients who didn't return as required in 3 months were surveyed by call and analyzed. RESULT: Among 574 cases, 472 cases passed both TEOAE and AABR hearing screening while admission. While 102 cases had abnormal test results in either screening test. Thirty-three cases returned for follow-up, 13 of which passed rescreening test one month after discharge, the other 20 cases had ABR diagnostic tests after 3 months. Among them, 8 cases had normal hearing, 12 cases had various degree of hearing loss. Sixty-nine cases lost follow-up. The reason of lost follow-up was as follows, parents changed phone number/contact information, parents didn't understand the screening results, parents believe that their children having no need for further testing; parents had retest in other hospitals, parents didn't pay attention to hearing loss because of other severe complicated comorbidities. CONCLUSION The passing rate (normal) of TEOAE and AABR hearing screening in NICU was 82.2%, non- passing rate wass 17.8%, and the prevalence of hearing loss was high in those followed cases. Hyperbilirubinemia was the main risk factors of hearing loss in our NICU patients. We reviewed the reason for high rate (67.6%) of losing follow-up.

Existing studies have underscored the pivotal role of N-acetyltransferase 10(NAT10)in various cancers.However,the outcomes of protein-protein interactions between NAT10 and its protein partners in head and neck squamous cell carcinoma(HNSCC)remain unexplored.In this study,we identified a significant upregulation of RNA-binding protein with serine-rich domain 1(RNPS1)in HNSCC,where RNPS1 inhibits the ubiquitination degradation of NAT10 by E3 ubiquitin ligase,zinc finger SWIM domain-containing protein 6(ZSWIM6),through direct protein interaction,thereby promoting high NAT10 expression in HNSCC.This upregulated NAT10 stability mediates the enhancement of specific tRNA ac4C modifications,subsequently boosting the translation process of genes involved in pathways such as IL-6 signaling,IL-8 signaling,and PTEN signaling that play roles in regulating HNSCC malignant progression,ultimately influencing the survival and prognosis of HNSCC patients.Additionally,we pioneered the development of TRMC-seq,leading to the discovery of novel tRNA-ac4C modification sites,thereby providing a potent sequencing tool for tRNA-ac4C research.Our findings expand the repertoire of tRNA ac4C modifications and identify a role of tRNA ac4C in the regulation of mRNA translation in HNSCC.
