OBJECTIVES: To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia. METHODS: A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis. RESULTS: Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%, CONCLUSIONS Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

OBJECTIVE: To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. METHODS: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period. RESULTS: After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year. CONCLUSION Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

Background:Chronic kidney disease (CKD) with moderate-to-severe renal dysfunction usually exhibits an irreversible course,and available treatments for delaying the progression to end-stage renal disease are limited.This study aimed to assess the efficacy and safety of the traditional Chinese medicine,Niaoduqing particles,for delaying renal dysfunction in patients with stage 3b-4 CKD.Methods:The present study was a prospective,randomized,double-blind,placebo-controlled,multicenter clinical trial.From May 2013 to December 2013,300 CKD patients with an estimated glomerular filtration rate (eGFR) between 20 and 45 ml,min-1· 1.73 m-2,aged 18-70 years were recruited from 22 hospitals in 11 Chinese provinces.Patients were randomized in a 1∶1 ratio to either a test group,which was administered Niaoduqing particles 5 g thrice daily and 10 g before bedtime for 24 weeks,or a control group,which was administered a placebo using the same methods.The primary endpoints were changes in baseline serum creatinine (Scr) and eGFR after completion of treatment.The primary endpoints were analyzed using Student's t-test or Wilcoxon's rank-sum test.The present study reported results based on an intention-to-treat (ITT) analysis.Results:A total of 292 participants underwent the ITT analysis.At 24 weeks,the median (interquartile range) change in Scr was 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the test and control groups,respectively (Z =2.642,P =0.008),and the median change in eGFR was-0.2 (-4.3-2.7) and-2.2 (-5.7-0.8) ml·min-1.1.73 m-2,respectively (Z =-2.408,P =0.016).There were no significant differences in adverse events between the groups.Conclusions:Niaoduqing particles safely and effectively delayed CKD progression in patients with stage 3b-4 CKD.This traditional Chinese medicine may be a promising alternative medication for patients with moderate-to-severe renal dysfunction.

OBJECTIVETo explore the mechanism and effect of maternal high-fat diet before and during pregnancy on bone growth of neonatal offspring rats.

METHODSForty female Sprague-Dawley rats were divided into high-fat diet and control groups (n=20) that were fed with 35% high-fat diet and standard chow, respectively. After 8 weeks, 8 female rats from each group were sacrificed for liver pathological examinations and the other female rats were mated with male rats and fed continuously with 35% high-fat diet and standard chow throughout gestation, respectively. The body lengths (from apex nasi to end of tail) of the offspring rats from both groups were measured within 24 hours after birth. Enzyme-linked immunosorbent assay was used to detect serum insulin-like growth factor (IFG-I) levels. Liver pathological changes were observed under a light microscope. The expression of insulin receptor substrate 1 (IRS-1) and phosphorylation IRS-1 (Phospho-IRS-1) in tibia and femur samples were detected by immunohistochemistry. The expression of mitogen-activated protein kinase (MAPK) and phosphorylation MAPK (Phospho-MAPK), phosphatidylinositol 3-kinase (PI3K) and phosphorylation PI3K (Phospho-PI3K), protein kinase B (AKT1) and phosphorylation AKT1 (Phospho-AKT1) in tibia and femur samples were detected by Western blot.

RESULTSThe offspring rats from the high-fat diet group showed a significant shorter body length compared with those from the control group (P<0.05). The level of serum IGF-I in offspring rats from the high-fat diet group decreased by 20.1% in comparison to those from the control group, but there was no significant difference between the two groups (P>0.05). Fatty degeneration was found in livers of both high-fat diet-fed maternal rats and their offspring rats under a light microscope. There were no significant differences in IRS-1 and Phospho-IRS-1 expression in chondrocytes of tibia and femur samples between the offspring rats of the two groups (P>0.05). The protein expression of MAPK in chondrocytes of tibia and femur samples of offspring rats from the high-fat diet group was higher than that from the control group (P<0.05). There were no significant differences of PI3K and AKT1/Phospho-AKT1 between the offspring rats of the two groups (P>0.05).

CONCLUSIONSA maternal high-fat diet before and during pregnancy may affect the bone growth of offspring rats in utero, which is possibly associated with the decreased IGF-I level. However, further study on the exact mechanism of IGF-I on the bone growth is needed.

OBJECTIVETo investigate the effect of osthole on bone metabolism in rat femoral tissues in vitro.

METHODSThe rat femoral tissues were isolated in vitro. The optimal concentrations of ostehole (1×10(-5) mol/L) and estradiol (1×10(-8) mol/L) (the positive control) were selected by alkaline phosphatase activity (ALP). The ALP and calcium levels were detected by commmerical regents, and the expressions of osteoprotegerin, receptor activator of nuclear factor-κB ligand, runx-related gene 2, and bone morphogenetic protein-2 mRNA were determined by real-time reverse transcription-polymerase chain reaction.

RESULTThe osthole (1×10(-5) mol/L) significantly increased the activity of ALP, calcium level as well as the expressions of osteoprotegerin, receptor activator of nuclear factor-κB ligand, runx-related gene-2 and bone morphogenetic protein-2 mRNA in rat femoral tissues in vitro.

CONCLUSIONOsthole can improve calcium level and ALP activity and regulate the bone metabolism-related genes in rat femoral tissues.

OBJECTIVETo investigate the molecular mechanisms of icariin (ICA) in regulating the bone formation of osteoblasts and the bone resorption of osteoclasts.

METHODSPrimary osteoblast cell cultures were obtained from newborn rat calvarial. Calcified nodules were stained by alizarin red. The mRNA levels of osterix (OSX), runt-related transcription factor 2 (Runx-2), alkaline phosphatase (ALP), Collagen1, osteoprotegerin (OPG), and receptor activator of nuclear factor-ΚB ligand (RANKL) were analyzed by quantitative real-time RT-PCR, the protein levels of OPG, RANKL, and Collagen1 were examined by Western blotting, and the intracellular Ca(2+) concentration of osteoblasts was measured on a flow cytometer using the Cellquest program.

RESULTSCompared with control group, ICA markedly promoted bone formation by significant up-regulating the gene expressions of OSX, Runx-2,ALP, and Collagen1, the protein expression of Collagen1(all P<0.01), and the Ca(2+) concentration. Furthermore, ICA remarkably inhibited bone resorption by significant up-regulating the mRNA and protein expressions of OPG as well as the OPG/RANKL ratio.

CONCLUSIONSICA could promote bone formation of osteoblasts through inducting the gene expressions of OSX,Runx-2, ALP and Collagen1, and the protein expressions of Collagen1, and by increasing the Ca (2+) concentration. Moreover, ICA could inhibit bone resorption of osteoclasts through regulating OPG/RANKL signal pathway.

OBJECTIVETo compare the effect of icariin and genistein in the osteogenic differentiation of rat bone marrow stromal cells (rBMSC).

METHODRat marrow stromal cells were seperated in vitro, and the optimal concentration of genisten and icriin were screened. Genistein and icariin with the concentration of 1 x 10(-5) mol x L(-1) were adopted to intereven rBMSCs cultured in vitro. Alkaline phosphatase (ALP) was determined at 3, 6, 9, 12,15 d after intervention; calcified nodule was detected with alizarin red staining at 12 d; OXS, Runx-2, bone morphogenetic protein (BMP-2) and Collagen-I mRNA expression were observed with Real-time RT-PCR at 12, 24, 48, 72, 96 h.

RESULTGenistein and icariin with the concentration of 1 x 10(-5) mol x L(-1) could increase the activity of ALP and the content of Ca, regulate OXS, BMP-2, Runx-2 and Collagen-I mRNA expression.

CONCLUSIONIcariin showed a stronger effect in improving the osteogenic differentiation of rat bone marrow stromal cells than genistein.

OBJECTIVETo investigate the value of narrow band imaging (NBI) endoscopy in the detection of unknown primary tumor site with cervical lymph node metastases of squamous cell carcinoma.

METHODSFifty-three patients with cervical lymph node metastases of squamous cell carcinoma treated in our department between June 2009 and December 2011 were enrolled in this study. Their primary tumor site was not detected by routine computed tomography, magnetic resonance imaging and laryngoscopy. The nasopharyngolarynx was examined by NBI endoscopy to explore the primary tumor site.

RESULTSA total of 53 cases with cervical lymph node metastasis of squamous cell carcinoma from an unknown primary were examined under NBI endoscopy. The primary tumor site was confirmed by NBI examination in 47.2% (25/53) of patients, significantly better than routine radiology and endoscopy (0, P < 0.001). These primary tumors were small and superficial, with characteristic mucosal vascular morphologies. The superficial nasopharyngeal carcinomas under NBI examination showed the superficial thin branch-like or torturous line microvessels. The notable characteristics of the squamous cell carcinoma of oropharynx, hypopharynx and larynx was the well demarcated brownish area and scattered brown dots.

CONCLUSIONThe NBI endoscopy can provide better visualization of the morphology of superficial mucosal vasculature and improve the ability to detect possible primary cancer in patients with primary unknown cervical lymph node metastasis.
