Objective To analyze youth talents' scientific research projects in research oriented hospital for recent five years,provide scientific basis for hospitals to strengthen the youth talents' capacity building of research innovation.Methods Identify those youth talents who have been funded in the First Affiliated Hospital of Xinjiang Medical University,and statistically analyze the demographic information,granted scientific research projects and hospital funding situations.Results There are 140 young talents who have got scientific research projects from 2011 to 2015 in the hospital.The national project number and the trend of approval rate has no obvious change;the provincial level project number and approval rate showed a trend of a significant increase in the last two years;Setting up the hospital fund promoted the youth talents' scientific research ability,but there are still spaces for further improvement in the funding field and founded group.Conclusions There has been a group of youth talents to stand out from the crowd during the construction and the development of the researchoriented hospital,but youth talents remains scarce for the national key projects and talent projects,and that will put forward new requirements for the hospital in the future to strengthen the youth talents' capacity building of research innovation,which needs to gradually establish a suitable cultivation mode and mechanism for youth talents' growth.

Objective To investigate the application of admission test as a medical management in the labor room.Methods Eight hundred and fifty singleton pregnant women underwent admission test in labor room at Women's Hospital,School of Medicine,Zhejiang University from Dec.2009 to Dec.2011 were enrolled into this study.They were divided into two groups:normal group (admission test was normal,n =658) and abnormal group (admission test was abnormal or undetermined,n =192).Deliveries and perinatal outcomes of them were observed.The difference between the two groups were compared with two independent sample t test and Chi-square test.Results There were no significant differences in the mean age at delivery of the women and mean birth weight of neonates between the two groups (all P＞0.05).The cesarean section rate of normal group (34.2％,225/658) was lower than that (59.4％,114/192) of abnormal group (x2=3.93,P＜0.05).The rates of prematurc rupture of membranes (72.4％,139/ 192),fetaldistress (42.2％,81/192),neonatal asphyxia (16.5％,27/192) and neonatal complications (31.8％,61/192) in abnormal group were significantly higher than those [31.0％ (204/658),24.2％ (159/ 658),0.2％(1/658) and 2.6％ (17/658)] in normal group (x2 =105.78,40.84,52.54 and 151.92,P＜0.01respectively).Conclusions Admission test is a good method to forecast placental function during labor and perinatal outcomes,which might play an important role in medical management in labor room.

Objective:To investigate the immunoregulation effect of ovalbumin immune tolerance factors (OVA ITFs).Methods:Components that were smaller than 3 kD were isolated from the splenic lymphocytes lysates of OVA tolerance mice or naive mice,respectively,named as OVA ITFs or OVA ITFs conttrol.Naive BALB/c mice were divided into 5 groups,group A,B,C,D were injected i.v.by OVA ITFs,OVA ITFs control,splenic lymphocytes from OVA tolerant mice or PBS,respectively,group E as the blank control.The percentages of CD4+CD25+ T cell subpopulation from spleens before and after adoptive transfer were measured with flow cytometer;OVA specific lymphocyte responses were assessed by MTT assay.The levels of IL-10 and TGF-?1 in the culture supernatants were tested by ELISA kits.Results:For OVA ITFs or splenic lymphocytes from OVA tolerant mice,the percentages of CD4+CD25+ T cell subpopulation from spleens after adoptive transfer were raised significantly compared with that before adoptive transfer (15.32%?1.03% and 15.35%?0.62% vs 9.97%?1.38%,P

Objective:To report a Chinese family with a novel ABCD1 gene mutation at c.332T>G (p.V111G) site and discuss its clinical characteristics and molecular mechanism.Methods:The clinical data, laboratory examination, and imaging examination results were analyzed to make the clinical diagnosis of a middle-aged onset patient from the First Affiliated Hospital of Zhengzhou University in May 2017. High-throughput sequencing was used to discover a novel ABCD1 gene mutation. Sanger sequencing was used to find out whether other family members contain the same ABCD1 gene mutation. The pathogenicity of this mutation was explored by protein structure prediction and pathogenicity analysis. Adrenoleukodystrophy protein-green fluorescent protein (ALDP-GFP) and ALDP-GFP (V111G) plasmids were constructed and human embryonic kidney 293 cells were transfected, then immunofluorescence and Western blotting were used to explore the molecular mechanism of this mutation (completed in Henan Provincial People′s Hospital).Results:The proband (a 39-year-old male) was diagnosed as adrenomyeloneuropathy, a subset of X-linked adrenoleukodystrophy, with a novel heterozygous missense mutation in the ABCD1 gene at c.332T>G (p.V111G) site, and his mother and two daughters were all carriers. Protein structure prediction and pathogenicity results suggested that this mutation is pathogenic. Overexpression of ALDP-GFP (V111G) in the human embryonic kidney 293 cells resulted in a significant decrease in the expression levels of ALDP and the abnormal localization from the peroxisomal membrane to the cytoplasm, accompanied by significant down-regulation of LC3-Ⅱ/LC3-Ⅰ and beclin-1.Conclusion:c.332T>G (p.V111G) is a novel pathogenic mutation in the ABCD1 gene, which causes adrenomyeloneuropathy by impairing autophagy.

Objective To evaluate the clinical outcome of external bracket fixation in the treat- ment of complex tibia diaphysis fracture involving intra-articular fractures.Methods Forty-two cases of complex tibia diaphysis fracture with proximal and distal intra-articular fractures treated surgically in our hospital from January 1999 to January 2004 were analyzed.The complex tibia diaphysis fractures were categorized according to the AO classification as type C2 (multiple segments fracture) and type C3 (ir- regular fracture),proximal and distal intra-articular fractures in 23 and 19 cases,respectively.Definite operation was done within one week.Twenty-two cases were treated with simple external fixator,and 20 cases treated with screws and external fixator.Results All the 42 cases were followed-up regularly. According to AO evaluation of the knee and ankle joint movement,83% (35/42 cases) of the cases gained satisfactory functional outcome,14% (6/42 cases) had quite satisfactory results and 2% (1/42 case) had unsatisfactory functional outcome.Conclusion External bracket fixation can obtain outcome of relative length of the tibia and fibula,tube structure reconstruction,smoothness of the articular surface and the parallel and symmetric relation of knees and ankles for complex tibia diaphysis fracture with proxi- mal and distal intra-articular fracture.The arthritis resulting in pain in movement and restriction of func- tion is considered to be the most important factor affecting the joint function.Early functional exercise is important for best recovery of knee and ankle function.

In order to identify Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix using ITS2 barcodes, genomic DNA from sixty samples was extracted and the ITS2 (internal transcribed spacer) regions were amplified and sequenced. The genetic distances were computed using MEGA 5.0 in accordance with the kimura 2-parameter (K2P) model and the neighbor-joining (NJ) phylogenetic tree was constructed. The results indicated that for Aucklandiae Radix (Aucklandia lappa), Vladimiriae Radix (Vladimiria souliei and V. souliei var. cinerea), Inulae Radix (Inula helenium), Aristolochiae Radix (Aristolochia debilis) and Kadsurae Radix (Kadsura longipedunculata), the intra-specific variation was smaller than inter-specific one. There are 162 variable sites among 272 bp after alignment of all ITS2 sequence haplotypes. For each species, the intra-specific genetic distances were also smaller than inter-specific one. Furthermore, the NJ tree strongly supported that Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix can be differentiated. At the same time, V. souliei (Dolomiaea souliei) and V. souliei var. cinerea( D. souliei var. cinerea) belonging to Vladimiriae Radix were clearly identified. In conclusion, ITS2 barcode could be used to identify Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix. Our study may provide a scientific foundation for clinical safe use of the traditional Chinese medicines.
