Objective To investigate the characteristics of epitope distribution on HLA class Ⅰ antigen in the regular platelet donors from Nanjing area and establish the HLA epitope database for regular platelet donors.Methods High-resolution HLA typing was per-formed using Sanger method for the blood samples from 649 regular platelet donors in Nanjing area.The polymorphism of HLA antigen epitopes corresponding to the high-resolution HLA typing results was analyzed using the HLA Eplet Registry website.The frequencies of allele frequencies,HLA haplotype,and HLA antigen epitope were calculated by using the direct counting method.Results Among the 649 regular platelet donors,38 HLA-A alleles were detected,corresponding to 36 HLA-A epitopes,and the higher frequencies were 79GT,144K and 138MI.Seventy-three HLA-B alleles were detected corresponding to 35 HLA-B epitopes,and the higher frequencies were 131S,69TNT,and 80N.Sixty-four HLA class Ⅰ antigen epitopes were detected,in which the higher frequencies were 79GT,131S,and 144K.Conclusions The distribution of HLA antigen epitopes in the regular platelet donors of Nanjing area exhibited u-nique polymorphic characteristics.The epitope matching strategies should be established based on the distribution characteristics of HLA antigen epitopes,which may expand the range of available donors and reduce the incidence of platelet transfusion refractoriness.

Objective To assess the effects of vascular endothelial growth factor-C (VEGF-C)/vascular endothelial growth factor receptor-3 (VEGFR-3) signaling on nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression in human osteosarcoma MG63 cells and the subsequent impact on the proliferation of human umbilical vein endothelial cells (HUVECs). MethodsMG63 cells were treated with VEGF-C alone (VEGF-C group), VEGF-C + iNOS inhibitor aminoguanidine (AG; AG group), and VEGF-C + VEGFR-3 inhibitor MAZ51 (MAZ51 group); untreated MG63 cells were used as controls. NO production was evaluated by a colorimetric method involving nitrate reductase. Meanwhile, mRNA and protein levels of iNOS were examined by reverse transcription polymerase chain reaction (RT-PCR) and Western blot. To explore the effect of VEGF-C/VEGFR-3/iNOS signaling of MG63 cells on proliferation of HUVECs, we set up six groups: HUVECs, HUVECs+MG63, HUVECs+VEGF-C, HUVECs+MG63+VEGF-C, HUVECs+MG63+VEGF-C+AG, and HUVECs+MG63+VEGF-C+MAZ51 groups. The proliferation of HUVEC cells was assessed by Cell Counting Kit-8 (CCK-8), 5-ethynyl-2'-deoxyuridine (EdU) incorporation assay, and proliferating cell nuclear antigen (PCNA) expression quantitation. ResultsVEGF-C treatment enhanced iNOS expression at both gene and protein levels (mRNA: LSD-

Purpose: The aim of this study was to compare the efficacy of liver transplantation (LT) and liver resection (LR) for hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) and to investigate risk factors affecting prognosis. Materials and Methods: A total of 94 HCC patients with PVTT type I (segmental PVTT) and PVTT type II (lobar PVTT) were involved and divided into LR (n=47) and LT groups (n=47). Recurrence-free survival (RFS) and overall survival (OS) were compared before and after inverse probability of treatment weighting (IPTW). Prognostic factors for RFS and OS were explored. Results: Two treatment groups were well-balanced using IPTW. In the entire cohort, LT provided a better prognosis than LR. Among patients with PVTT type I, RFS was better with LT (p=0.039); OS was not different significantly between LT and LR (p=0.093). In subgroup analysis of PVTT type I patients with α-fetoprotein (AFP) levels >200 ng/mL, LT elicited significantly longer median RFS (18.0 months vs. 2.1 months, p=0.022) and relatively longer median OS time (23.6 months vs. 9.8 months, p=0.065). Among patients with PVTT type II, no significant differences in RFS and OS were found between LT and LR (p=0.115 and 0.335, respectively). Multivariate analyses showed treatment allocation (LR), tumor size (>5 cm), AFP and aspartate aminotransferase (AST) levels to be risk factors of RFS and treatment allocation (LR), AFP and AST as risk factors for OS. Conclusion LT appeared to afford a better prognosis for HCC with PVTT type I than LR, especially in patients with AFP levels >200 ng/mL.

Objective Comprehensively considering the effectiveness and safety of massage, a method for evaluating the pros and cons of oscillation excitation and pulse excitation for lumbar oblique-pulling manipulation was proposed, and lumbar oblique-pulling manipulation under oscillation excitation was optimized. Methods A multi-rigid body biomechanical model of thoracolumbar spine was established. The manipulation force was used as the input force of the model. Using MATLAB/Simulink, variation of the displacement and acceleration of each lumbar segment with time was simulated. For the optimization of lumbar massage manipulation, the core elements of massage force, namely, frequency (f) and operand (n) were changed, and then the maximum relative displacement and maximum acceleration of each lumbar segment were compared. A new index z was proposed to comprehensively evaluate effectiveness and safety of the manipulation. Results The maximum relative displacement of each lumbar segment was almost equal when lumbar oblique-pulling manipulation under two kinds of excitation was applied. For lumbar oblique-pulling manipulation, the maximum acceleration of each lumbar segment under oscillation excitation was significantly smaller than that under pulse excitation. When the frequency of massage was 1-2.5 Hz, the overall effect of massage was better, and the overall effect had no relation with the operands, and the force of massage lasted for one operand; when the frequency of message was 3.33 Hz and the operands were more than 5, the massage had the best effect, meanwhile the strength of each lumbar segment was relatively large; when the frequency of massage exceeded 5 Hz, and the overall performance of massage was not good. Conclusions Lumbar oblique-pulling manipulation under oscillation excitation is safer than that under pulse excitation. The research findings provide doctors with a reasonable range of operating parameters for lumbar oblique-pulling manipulation under pulse excitation.

Hyperlipidemia is a major risk factor for fatty liver, atherosclerosis, hyperviscosily, coronary artery disease and acute myocardial infarction. In recent years, the incidence of hyperlipidemia was gradually increased and showed younger trend. It has been a research hot point to study the etiology and pathogenesis of hyperlipidemia and develop a new drug reduced blood lipid. It is very important to prepare the animal model of hyperlipidemia for displaying the advantage of traditional Chinese medicine characteristic. However, the success of replicating animal model of hyperlipidemia is one of the key of research in experimental hyperlipidemia. The ideal animal model of hyperlipidemia should be similar to human disease, high repeatability, simple and high generalization. It will affect the reliability of the results and the accuracy of the whole experiment process to copy successfully animal models of hyperlipidemia. This review focused on the recent research progress on copying methods of animal models of experimental hyperlipidemia, which will provide reference and basis for the hypolipidemic developers who choose rationally and effectively replication methods of hyperlipidemia animal models.

OBJECTIVETo investigate the effects of silencing ADP-ribosylation factor 6 (Arf6) on the proliferation, migration, and invasion of prostate cancer cell line PC-3 and the possible molecular mechanisms.

METHODSThree Arf6-specific small interfering RNA (siRNA) were transfected into cultured prostate cancer cell line PC-3. Arf6 expression was examined by real-time PCR and Western blotting. MTT assay, wound healing assay, and Transwell migration and invasion assay were used to observe the effect of Arf6 silencing on the proliferation, migration, and invasion ability of PC-3 cells. The levels of phosphorylated extracellular signal-regulated kinase 1/2 (p-ERK1/2), ERK1/2, p-AKT, AKT and Rac1 were detected by Western blotting.

RESULTSTransfection of siRNA-3 resulted in significantly decreased Arf6 mRNA and protein expression with inhibition rates of (91.88±3.13)% and (86.37±0.57)%, respectively. Arf6 silencing by siRNA-3 markedly suppressed the proliferation, migration and invasion of PC-3 cells and reduced the expression levels of p-ERK1/2 and Rac1.

CONCLUSIONSilencing of Arf6 efficiently inhibits the proliferation, migration, and invasion of PC-3 cells in vitro, and the underlying mechanisms may involve the down-regulation of p-ERK1/2 and Rac1.

OBJECTIVETo analyze the whole microbial structure in a case of rampant caries to provide evidence for its prevention and treatment.

METHODSClinical samples including blood, supragingival plaque, plaque in the caries cavity, saliva, and mucosal swabs were collected with the patient's consent. The blood sample was sent for routine immune test, and the others samples were stained using Gram method and cultured for identifying colonies and 16S rRNA sequencing. DNA was extracted from the samples and tested for the main cariogenic bacterium (Streptococcus mutans) with qPCR, and the whole microbial structure was analyzed using DGGE.

RESULTSThe patient had a high levels of IgE and segmented neutrophils in his blood. Streptococci with extremely long chains were found in the saliva samples under microscope. Culture of the samples revealed the highest bacterial concentration in the saliva. The relative content of hemolytic bacterium was detected in the samples, the highest in the caries cavity; C. albicans was the highest in the dental plaque. In addition, 33 bacterial colonies were identified by VITEK system and 16S rDNA sequence phylogenetic analysis, and among them streptococci and Leptotrichia wade were enriched in the dental plaque sample, Streptococcus mutans, Fusobacterium nucleatum, and Streptococcus tigurinus in the caries cavity, and Lactobacillus in the saliva. S. mutans was significantly abundant in the mucosal swabs, saliva and plaque samples of the caries cavity as shown by qPCR. Compared to samples collected from a healthy individual and another two patients with rampant caries, the samples from this case showed a decreased bacterial diversity and increased bacterial abundance shown by PCR-DGGE profiling, and multiple Leptotrichia sp. were detected by gel sequencing.

CONCLUSIONThe outgrowth of such pathogenic microorganisms as S. mutans and Leptotrichia sp., and dysbiosis of oral microbial community might contribute to the pathogenesis of rampant caries in this case.

OBJECTIVETo investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.

METHODSThe registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).

RESULTSThe preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).

CONCLUSIONPROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.
