A method was developed for analyzing the stable carbon isotope ratio of five volatile components ( Ethanol, Glycerol, Acetic acid, Ethyl lactate, 2-methyl-butanol ) in wine using gas chromatography-combustion-isotope ratio mass spectrometer ( GC-C-IRMS ) . The sample injection volume was less than 0. 5 μL, and the analytical time of each run was less than 14 min. The precision of this method was 0. 08‰-0. 25‰ for analyzing standards, while 0. 09‰-0. 36‰ for wine samples. Compared to element analysis-isotope ratio mass spectrometry ( EA-IRMS) results, the deviations were lower than 0. 5‰. Fifty-four wine samples from France, Australia, America and China were considered. The δ13 C of five volatile components were measured using GC-C-IRMS. Discriminant analysis ( DA) was employed for analyzing the geographical origin traceability of selected wine. The result indicated that δ13 C of volatile components could be used to distinguish the origin of wines. The method was shown to be effective in improving detection of the origin traceability of wine.

Objective To investigate the clinical outcome of arthroscopic percutaneous cannulated screw fixation with subtalar fusion in the treatment of post-traumatic subtalar arthritis. Methods The study involved 12 patients (five males and seven females) with severe post-traumatic subtalar arthritis admitted to our hospital from April 2006 to December 2009. The patients were at age range of 28-68 years ( mean 45.6 years). All patients had the history of conservative treatment but failed in pain alleviation.Then, the percutaneous cannulated screw fixation plus subtalar fusion was selected. The ande and hind foot of all patients were evaluated preoperatively and postoperatively by the American Orthopedic Foot and Ankle Society (AOFAS) scoring system. Imaging assessment was carried out by X-ray examination.Results The patients were followed up for mean 21.2 months (range 6-48 months), which showed thatthe mean AOFAS ankle-hindfoot scale was increased from (54.67 ± 5.28 ) points (range 43-61 points)preoperatively to (89.17 ±3.56) points (range 78-95 points) at final follow-up, with excellence rate of 93%. Eleven patients got good fusion with the mean time of 12.4 weeks (range 9-15 weeks). Only one patient had nonunion, with the pain in the lateral malleolus. The subtalar joint of the patient got union after plaster immobilization for three months, which was proved by X-ray examination. Conclusions The arthroscopic percutaneous cannulated screw fixation and subtalar fusion can acquire good clinical outcomes and hence is a recommended procedure for post-traumatic subtalar arthritis.

OBJECTIVE:
To investigate the effect and mechanism of glucagon like peptide 1(GLP-1)on the proliferation and differentiation of endothelial progenitor cells(EPCs)derived from the peripheral blood.
METHODS:
Mononuclear cells were isolated from human peripheral blood by density gradient centrifugation. After 7 days of culture,attached cells were stimulated with different cultures of 0.2% BSA,and GLP-1(1,10,and 20 nmol/L). Laser scanning confocal microscope was used to determine the EPCs from human peripheral blood.The activity of EPCs was observed under reverse microscope. MTT was used to determine the proliferation of EPCs. The expression of KDR,Flt-1,VE-cadherin,and eNOS mRNA was detected by RT-PCR.The concentration of serum VEGF was detected by ELISA. The expression of VEGF protein was detected by immunohistochemical SP method. The EPCs cultured in GLP-1 were intervened by VEGFmAb.
RESULTS:
EPCs was proliferated more in the GLP-1 group(1,10,and 20 nmol/L) than in the control group (P<0.05 or P<0.01). The expression of KDR,FLT-1,VE-cadherin,eNOS mRNA and VEGF protein was higher than that in the control group(P<0.05 or P<0.01). VEGFmAb(100 ng/mL)down-regulated the expression of KDR,Flt-1,VE-cadherin,and eNOS mRNA.
CONCLUSION
GLP-1 can promote the proliferation and differentiation of EPCs derived from the peripheral blood by up-regulating VEGF autocrine.

OBJECTIVETo investigate the expression of protein tyrosine phosphatase non-receptor type 2 (PTPN2) and nuclear factor-kappaB (NF-kappaB), as well as the relationship between their expression and periodontal destruction in mice with diabetic periodontitis.
METHODSFour weeks old healthy C57BL/6J mice were randomly divided into normal control group (Group N), periodontitis group (Group P) and diabetic periodontitis group (Group DP), and each group had six mice. Mice in Group P were inoculated Porphyromonas gingivalis orally to induce periodontitis. Mice in Group DP had high sugary and fatty food, streptozotocin intraperitoneal injection and Porphyromonas gingivalis oral inoculation to induce diabetic periodontitis. All mice were sacrificed 4 weeks after the last bacterium inoculation of Groups P and DP. Stereo microscope was chosen to detect morphological changes and bone loss areas of the alveolar bone. Hematoxylin-eosin (HE) staining was selected to observe loss heights of periodontal attachment. Immunohistochemical staining was used to detect PTPN2 and NF-kappaB expression in periodontal tissues.
RESULTSGroup P and Group DP had significantly more attachment loss heights and areas than Group N (P < 0.05), and showed less PTPN2 expression (P < 0.05) and higher NF-kappaB levels (P < 0.01).
CONCLUSIONPTPN2 may negatively regulate the development of diabetic periodontitis, while NF-kappaB may have opposite effects. PTPN2 down-regulation might contribute to NF-kappaB over-expression leading to exacerbated periodontal destruction.

Objective To investigate pathogenic genes related to the phenotype of fetus with severely short limbs in the first and second trimester by whole exome sequencing (WES). Methods Thirteen fetuses with severely short limbs detected by ultrasonography in the first and second trimester admitted in Chinese PLA General Hospital from September 2016 to June 2018 were collected. All cases were performed induced abortion, 6 of which were carried out karyotype analysis of amniotic fluid at the same time. WES and copy number variations (CNV) were performed on specimens from fetal tissues after labor induction. The suspected pathogenic mutations were validated by Sanger sequencing reactions. Results No abnormal karyotypes or pathological CNV were found. In 10 fetuses, pathogenic or possibly pathogenic mutations were detected in the following genes: COL2A1, FGFR3, COL1A1, COL1A2, DYNC2LI1 and TRIP11, all of which were essential to skeletal development. The diagnostic yield of WES in the fetuses with severe short limbs was 10/13. Conclusions In the first and second trimester, most of the fetuses with extremely short limbs suffer from monogenic diseases. WES is likely to be a valuable diagnostic testing option for the fetuses with severe short limbs.

Objective:Kallmann syndrome(KS) is a complex genetic disease characterized by congenital hypogonadotropic hypogonadism and anosmia. More than 20 genes have been reported to be associated with KS. Herein, we explore potential genetic aberration in 3 KS patients using the whole-exome sequencing. The potentially pathogenic variants filtered were validated by Sanger sequencing.Methods:Genomic DNA was extracted from the peripheral blood of 3 patients with KS and their family members. Sanger sequencing and pedigree verification were performed on the pathogenic variants identified using whole-exome sequencing. The function of the mutation sites were analyzed with bioinformatics software.Results:The proband 1 was a 25 years old male, characterized by lower gonadotropin gonad hypofunction, early grey hair and bilateral sensorineural hearing loss. A heterozygous mutation c. 475C>T(p.R159W) of SOX10 gene was detected in the proband 1. His mother, sister and cousin who had KS phenotype were also found carrying this mutation, showing an autosomal dominant inheritance. The proband 2 was a 15-year-old male with hypogonadotropic hypogonadism and unilateral renal agenesis. The proband was hemizygous for c. 844delC(p.R282Vfs*28) of ANOS1 gene, his mother was heterozygous for the mutation, which was consistent with the X-linked recessive inheritance. The proband 3 was a 21 years old female, characterized by hypogonadotropic hypogonadism and anosmia. A heterozygous missense mutation c. 149G>A(p.R50Q) was detected in FGF17 gene. The mutation p. R50Q was predicted to be pathogenic by the SIFT and PolyPhen2 programs, and has not been reported in HGDM database yet, which considered to be a novel mutation.Conclusion:KS is a clinically and genetically heterogeneous disease. In this study, ANOS1 c. 844delC, SOX10 c. 475C>T and FGF17 c. 149G>A mutations were found in 3 patients with KS by whole exome sequencing, which would expand the genotypic and phenotype spectrum of KS.
