ABSTRACT
Objective:To investigate the effects of gestational diabetes mellitus (GDM) on neonatal metabolites.Methods:This retrospective cohort study recruited 580 singleton newborns who were born to women with GDM from January 2018 to December 2018 in Foshan Maternal and Child Health Care Hospital as the GDM group. Another 580 counterparts born to non-GDM singleton mothers with matching age were selected as the non-GDM group with an allocation ratio of 1 to 1. Neonatal genetic metabolic disease screening was performed within 3-7 days after birth. Two independent sample t-test, and multiple linear regression model were used for statistical analysis. Results:There were significant differences in seven amino acids and 10 fatty acids levels between the GDM and non-GDM group. The serum levels of six amino acids and eight fatty acids were increased in the GDM group, while the levels of piperamide [(140.79±32.60) vs (150.26±35.46) μmol/L, t=－4.733, P<0.001], palmitoyl carnitine [(2.59±0.81) vs (2.73±0.82) μmol/L, t=－2.940, P=0.003], and carbamate [(0.066±0.022) vs (0.069±0.022) μmol/L, t=－1.937, P=0.042] were decreased compared with the non-GDM group. After adjusting for maternal gravidity, parity, neonatal birth weight, and gender, multivariate linear regression analysis showed that GDM was positively correlated with three amino acids levels, which were cysteine ( ?=0.012), homocysteine ( ?=0.263) and leucine ( ?=4.225); and was negatively correlated with glycine ( ?=－6.271) and piperamide level ( ?=－9.885). With regard to the fatty acids, GDM was positively correlated with the neonatal propionyl carnitine ( ?=0.214), butyryl carnitine ( ?=0.014), 3-hydroxybutyryl carnitine ( ?=0.006), isovaleryl carnitine ( ?=0.009), 3-hydroxyisovaleryl carnitine ( ?=0.024), hexadecanoyl carnitine ( ?=0.001), decadienoyl carnitine ( ?=0.045), octadecadienyl carnitine level ( ?=0.128), but was negatively correlated with palmitoyl carnitine ( ?=－0.119), and carbamate ( ?=－0.002) (all P<0.05). Conclusions:Correlations between maternal GDM and the levels of amino acids and fatty acids in neonates was noted in this study, suggesting that maternal GDM may affect the metabolism of amino acids and fatty acids in offspring at early stage of life.
ABSTRACT
OBJECTIVE@#To detect potential variant in an ethical Han Chinese pedigree affected with breast cancer.@*METHODS@#The proband and her relatives were subjected to next-generation sequencing using a target capture sequencing kit containing 121 cancer-related genes. Candidate variants were selected by analysis of their type, frequency in population, and segregation with the phenotype. Candidate variant was verified by Sanger sequencing and TA cloning.@*RESULTS@#A c.2013_2014ins GT variant was detected in the BRCA1 gene among all breast cancer patients from this pedigree but not among healthy females. The variant was not recorded in the 1000 Genome Project database or the Exome Aggregation Consortium (ExAC) database. The frameshifting insertion was predicted to form an premature stop codon in gene transcript and can give rise to a truncated protein.@*CONCLUSION@#The BRCA1 c.2013_2014ins GT variant probably underlies the pathogenesis of breast cancer in this Chinese pedigree.

Objective To estimate the value of neck circumference in diagnosis of metabolic syndrome. Methods We analyzed the neck circumference of 523 volunteers and the occurrence of metabolic syndrome among them. Then we updated and revalued their data after follow-up for 1.5 years, meanwhile, we evaulated the value of Body Mass Index (BMI) and neck circumference in predicting metabolic syndrome. Results The increase of neck circumference was closely related to the occurrence of metabolic syndrome , and this tendency continued in the follow-up. Compared with BMI , neck circumference was sensitive in identifying the patients of metabolic syndrome. Conclusion Neck circumference has great value in diagnosis and treatment of metabolic syndrome.

ABSTRACT
Objective To investigate the effect of early insulin therapy on NF-KB pathway and inflammatory cytokine responses in fiver of diabetic rat.Methods NF-KB p65 DNA binding was assayed with ELISA-based assay kit,cytokine gene expressions were quantified with real-time PCR and phosphoenolpyruvate carboxykinase(PEPCK),NF-KB and inhibitor KB(IKBα)protein levels wlere assayed with Westem blot.Results Compared with control,hepatic PEPCK protein level in the untreated diabetic rat increased by 40%.Early insulin and gliclazide treatment normalized PEPCK protein level.The abundance of IKBα protein was significantly decreased and nuclear NF-KB p65 DNA binding activity was incteased in untreated diabetic rats.IKBot protein content increased and NF-KB p65 DNA binding decreased during early intervention treatment.mRNAs encoding IL-1β and TNFα were increased,which were reduced to normal levels after insulin and gliclazide treatment.Conclusions It is suggested that early insulin treatment inhibits NF-KB activity and inflammatory cytokine responses in fiver that are involved in the aniefioration of insulin resistance in diabetic rats.Such results misht be due to indirect antiinflammatory effects of insulin thus relieving glucotoxicity and lipotoxicity in pefipherM tissues.
ABSTRACT
Objectives To investigate the epidemiological and clinical characteristics of dyslipidemia as well as its treatment and influence on accompanying diseases in impaired glucose status among inpatients. Methods A cross-sectional survey was conducted among the inpatients registered in ten university hospitals of Guangdong, China during the week before the Diabetes Day in 2004. The fasting blood glucose (FBG), lipid profiles, BMI, waist to hip ratio (WHR) and concomitant disorders of the first screen during the hospitalization period were recorded. Those who had FBG level from 5.6 to 6. 9 mmol/L and not been previously diagnosed diabetes (PDM) underwent oral glucose tolerance test (OGTF). Results Of the 8753 inpatients investigated, 1067 eases had complete medical records(CMR case) including PDM cases and previously non-diagnosed diabetes ones with FBG ≥ 5. 6 mmol/L. Of the previously non-diagnosed diabetes cases with FBG levels from 5.6 to 6.9 mmmol/L, 65.8% accepted OGTT. Of the CMR cases, 41.9% had PDM, 21.7% was newly diagnosed diabetes mellitus (NDM), 29. 1% had impaired glucose regulation (IGR) and only 7.3% had normal glucose tolerance (NGT). The TG levels in NDM and PDM group were higher than those in IGR and NGT group (P < 0.05, respectively). The HDL-C levels in IGR, NDM and PDM group were lower than those in NGT group (P < 0.05, respectively). Sixty-nine point six percent of the diabetes mellitus (DM) inpatients was accompanied with dyslipidemia and the rate was higher than those in NGT (56.4%) and IGR inpatients (52.5%, P <0.05, respectively). Only 22. 8% of the PDM inpatients underwent treatment of dyslipidaemia and just 3.4% achieved the target suggested by the guideline of ATP-Ⅲ. BMI was higher and waistline longer in the PDM and NDM inpatients than those in the NGT cases (P <0.05, respectively). Seventy-two point eight percent of the PDM inpatients was complicated with more than one type of vascular diseases. Nine point seven percent and 0. 2% of the NDM inpatients were tormented by diabetic nephropathy and diabetic retinopathy respectively. Conclusions More inpatients with accompany DM or IGR had concomitant dyslipidemia than those with NGT, which included hypertriglyccridemia, hypo-high-density lipoproteinemia and metabolic syndrome. Concomitant vascular diseases were more frequently found in PDM inpatients than in the others. Some of the NDM and IGT inpatients were complicated with microvascular diseases.

ABSTRACT
BACKGROUND: Recombinant human granulocyte colony-stimulating factor (rhG-CSF) can mobilize endothelial progenitor cells and enhance new vessels at cerebral ischemia region. OBJECTIVE: To investigate the effects of rhG-CSF on the new microvascular expressions in rat perihematoma after intracerebral hemorrhage. DESIGN, TIME AND SETTING: A randomized control animal experiment was performed at the Central Laboratory of Luzhou Medical College from March to November 2006. MATERIALS: A total of 72 healthy male Sprague Dawley rats and rhG-CSF were used for this study. METHODS: Seventy-two rats were equally and randomly assigned into the sham operation group, the hemorrhage group, the treatment group. According to rat brain stereotaxic atlas, models of intracerebral hemorrhage were made by infusing autoblood from rat tails. Rats in the sham operation group were infused with saline instead of autoblood. Rats in the treatment group were administered rhG-CSF (60 ?g/kg) by intraperitoneal injection at 1 hour after operation. Rats in the sham operation and hemorrhage groups were left intact. MAIN OUTCOME MEASURES: The microvascular expressions of CD34+ in perihematoma were detected at 6, 12, 24, 48 and 72 hours, 7 days; Four rats in each time point. Microvascular production was measured by changes in CD34. The more the CD34 antigens, the more the new vessels were. RESULTS: In the hemorrhage group, the microvascular expressions of CD34+ were significantly higher compared to the sham operation group (P 0.05). Significant differences were measured at 6, 12, 24 and 48 hours (P
ABSTRACT
AIM: Research report that bone marrow stem cells mobilized by recombinan human granulocyte colony-stimulating factor (rhG-CSF) can migrate to lesion spot of infarction, thus decrease brain edema and brain injury after cerebral ischemia. But the report about the effect of drug on brain edema after cerebral hemorrhage is rare. This study investigated the effects of bone mar- row stem cells mobilized by rhG-CSF on reducing formation of brain edema and downregulation of matrix metalloproteinase (MMP)-9 in the peripheral area after intracerebral hemorrhage (ICH) in rats. METHODS:The experiments were performed at the Central Laboratory of Luzhou Medical College from March to November in 2006. ① 144 healthy male SD rats, (300?20)g, were provided by Animal Department of Luzhou Medical College. The experimental procedures of disposing animals were accorded with ethical standards. ②Experimental rats were assigned randomly into a sham operation group, a ICH group and a treatment group, equally. According to the method of Yang, rat models of ICH were made by the method cutting off tail of rat to obtain autoblood in the ICH and treatment groups. Rats in the sham operation group received saline instead of autoblood. Rats in the treatment group were administered with rhG-CSF (60 ?g/kg) by intrap- eritoneal injection after 1 hour. ③The water contents and MMP-9 were measured in each group by immunohistochemical method. RESULTS:Of 144 rats, 16 rats dropped out, among which 7 rats were estimated as 0 grade and 9 rats died, and all were supple- mented. ①The water contents were higher in the ICH group than in the sham operation group (P
