OBJECTIVETo investigate the relationship between the changes of the copy numbers of mtDNA in peripheral blood mono-nucle- ar cell(PBMC) and the disordered of antioxidant capacity of hepatocellular carcinoma (HCC) patients.
METHODSThe Ficoll Hypaque method was used to isolate the PBMC from blood specimens. The ND1 gene of the mitochondrial was amplified by real-time PCR; meantime β-actin was served as a quantitative standard marker; the difference of mtDNA copy number in PBMC was compared between HCC and healthy control group. The level of reactive oxygen species (ROS) in PBMC was determined by flow cytometry. The change of total antioxidant capacity (T- AOC) of plasma was detected by the biochemistry examination.
RESULTSThe copy numbers of ND1 gene in PBMC of HCC was 73% that of the healthy control group,which suggested a decrease of the copy numbers of mtDNA in HCC. The levels of ROS of PBMC in HCC was (417. 82 ± 110.62) and (301.82 ± 75.54) in control group, which showed that the levels of ROS of PBMC in HCC were significant higher than that in control group (P < 0.01).Plasma T-AOC in HCC was (1.30 ± 0.85), and (3.20 ± 1.62) in control. The T-AOC of plasma of HCC was significantly lower than in control group (P < 0.01).
CONCLUSIONThere was a certain relationship between the decrease of the copy numbers of mtDNA and the disordered antioxidant capacity in hepatocellular carcinoma, which may be associated with the development of hepatocellular carcinoma.

OBJECTIVETo observe the effects of Stragalus membranaceus injection on nitric oxide and endothelin levels of intestinal mucosa in reperfusion injury after hemorrhage shock.
METHOD32 SD rats were randomly divided into four groups: normal group, model group, low dosage group, (treated with Astragalus membranaceus 10 g x kg(-1)); high dosage group (treated with Astragalus membranaceus 20 g x kg(-1)). Models of hemorrhagic shock for 60 minutes and reperfusion for 90 minutes were created. The animals were administrated 3 mL therapeutic solution before reperfusion. At the end of study, intestinal pathology was observed, and the concentration of lactic acid (LD), nitric oxide (NO), endothelin (ET) of intestinal mucosa were detected.
RESULTThe intestinal pathology showed that intestinal mucosa epithelial cells damage in model group was severe, in low dosage group was medium, in high dosage group was slight, and no obvious damage was found in normal group. The concentration of LD and NO of small intestine mucous membrane in model group and low dosage group were significantly higher than those in high dosage group and normal group (P < 0.05), but there were no significant differences between high dosage group and normal group (P > 0.05). The concentration of ET of small intestine mucous membrane in model group was the highest of the four groups (P < 0.05). The concentration of ET in low dosage group was significantly higher than that in high dosage group and normal group (P < 0.05), but there were no significant differences between high dosage group and normal group (P > 0.05).
CONCLUSIONStragalus membranaceus injection can reduce small intestine mucous damage by protecting endothelium function in injury after hemorrhage shock-reperfusion.

OBJECTIVETo assess bone health in epileptic children who have been treated with topiramate (TPM) or carbamazepine (CBZ).
METHODSSixty-three epileptic children who received TPM or CBZ treatment and 36 eileptic children who did not receive any drug treatment (control group) were enrolled. Bone mineral density (BMD) at lumbar vertebrae (L1-L4) and radius-ulna was evaluated by the dual-energy X-ray absorptiometry method. Biochemical indices of bone metabolism, including serum calcium, phosphorus and alkaline phosphatase contents were measured.
RESULTSThe serum calcium content was higher in the TPM group (2.41+/-0.17 mmol/L), but it was lower in the CBZ group (2.15+/-0.26 mmol/L) than that (2.26+/-0.11 mmol/L) in the control group (p<0.05). The serum phosphorus content in both the TPM (1.55+/-0.17 mmol/L) and the CBZ groups (1.52+/-0.26 mmol/L) was significantly lower than that in the control group (1.70+/-0.30 mmol/L) (p<0.05). There were no significant differences in the serum content of alkaline phosphatase between three groups. BMD was significantly reduced in both the TPM and the CBZ groups when compared to the control group (p<0.05).
CONCLUSIONSTPM and CBZ may result in alterations in serum contents of calcium, phosphorus and alkaline phosphatase as well as BMD reduction.

Objective To investigate the relationship between the pathological changes and the early anastomosis of the blood vessels in blast-wounded maxillofacial region. Methods A total of 20 dogs were regionally exploded in the left maxillofacial region by KTY-04 electric detonator. Specimens of blood vessels were removed at different distance from the edge of the wounded area at both right after (group A) and 72 h (group B ) after wounded and observed. Free skin flaps with saphenous artery were transplanted to the wounded areas. One week, 2 weeks and 3 months after anastomosis, specimens were taken from the site of anastomosis and observed. Results Falling off of most vascular endothelial cells and the disappearance of most internal elastic membrane of the artery were observed 3 cm from the wounded area in group A with 5 free flaps died. However in group B almost normal condition was seen at the same region. 12 from 15 flaps survived successfully. Conclusion The blood vessels begin to proliferate and repair 3 d after blast wound and this may provide the pathological basis for the possible success in the transplantation of the free flaps with blood vessels.

Background Researches showed that elevatory blood glucose level results in long-term damage of cells and tissue,or metabolic memory phenomenon,and manipulation of hyperglycemic memory is a good approach in the prevention of diabetic complications.However,its mechanism is not clear.It is speculated that the pathogenesis of diabetic retinopathy (DR) in diabetic patients may be associated to related mechanisms.Uncoupling proteins (UCPs) can decrease the production of reactive oxygen species (ROS),which may be related to DR.Objective This study was to explore the association between DR and the single nucleotide polymorphisms (SNPs) of UCP genes in Chinese Han population with type 2 diabetes.Methods A cross-sectional study was performed.This study was approved by Ethic Committee of Affiliated First Hospital of Shanghai Jiao Tong University and complied with Declaration of Helsinki,and written informed consent was obtained from each subject prior to any medical examination.One thousand eight hundreds and seventy-five patients with type 2 diabetes mellitus were enrolled in Xinjing district of Shanghai city by cluster sampling from November 2014 to January 2015.The demographic and medical baseline characteristics,ocular examination and laboratory tests were obtained and periphery blood of 2 ml was collected for extraction of DNA.Eight tag SNPs of UCP1,three tag SNPs of UCP2,and seven tag SNPs of UCP3 were selected as marker locus for the detection of genotype by Sequenom Mass ARRAY.Matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry platform were used for genotyping.Hardy-Weinberg equilibrium (HWE) analysis,allele and genotype frequencies,haplotype analysis,and association tests for DR and SNPs were performed by SAS and SHEsis software.Results A total of 530 DR patients were checked out from 1 875 subjects with type 2 diabetes mellitus,with the detection rate of 28.27%.rs660339 locn of UCP2 gene and rs1626521,rs668514 locus of UCP3 gene appeared to have low detectable rates,and the secondary allele base frequency of rs632862 in UCP2 gene was <0.01 and rs15763 of UCP3 gene was unmatched with HWE,therefore,these locus analysis was not included.In 13 SNPs locus included in the analysis,only 2 SNPs of UCP1 gene were related to DR.Compared with the non-diabetic retinopathy (NDR) patients,the G allele frequency of rs10011540 was increased (P =0.03,OR =1.31,95 % confidence interval[CI] =1.03-1.67,and T allele frequency of rs3811787 was decreased (P=0.04,OR=0.86,95% CI=0.75-0.99) in DR patients.Genotyping detection showed that the C/C and A/A frequencies of rs3811790 in UCP1 gene were significantly more and C/A frequency was less in DR patients than those in NDR patients (all at P<0.01).The logistic regression analysis indicated an association of SNPs of rs10011540 and rs3811787 with DR independent from glucose and disease duration.Conclusions The SNPs of rs10011540 and rs3811787 locus in UCP1 gene are associated with DR in Chinese type 2 diabetes patients.
