Objective To investigate the dynamic changes of platelets (PLT) and white blood cells (WBC) after traumatic brain injury (TBI) and discuss its clinical significance. Methods The number of PLT and WBC were examined in 63 patients with TBI by using cytoanalyze and also analyzed together with Glasgow Outcome Scale and concurrent infection, in the meantime, enzyme-linked immu-nosorbent was used to investigate concentration changes of C reactive protein (CRP) and thrombospondin 1 (TSPI) and analyze the correlation between CRP and TSP1. Results The number of WBC in all pa-tients, whether concurred with infection or not, was significantly increased within 24 hours after TBI (P < 0.01), with no statistical difference between patients without infection at day 4 and normal patients (P >0.05). However, the number of WBC was decreased to below 10 × 109/L in patients without infec-tion, which was significantly higher than that in normal patients (P < 0.05). In patients with infection and unfavorable prognosis, the number of WBC was increased again ay days 7-14, whereas that of PLT rose significantly at days 14-21 (P <0. 01). The concentration of TSPI was positively correlated with that of CRP (r = 0.720, P < 0.01). Conclusions Monitoring the dynamic changes of PLT and WBC is promising. The change of WBC at day 4 post injury is a key indicator to provide evidences of prophylactic antibiotic usage. Much attention should be paid to the dynamic change of PLT at days 14-21 post injury so as to evaluate the condition of hypercoagulability that can be potentially caused by inflammation response. Secondary increase of WBC and later increase, of PLT may affect prognosis of the patients. TSP1 and CRP may participate in thrombosis formation induced by inflammation.

SUMOylation is an important post-translational modification of proteins. Similar to ubiquitylation, SUMOylation is the process that the small ubiquitin-like modifier (SUMO) proteins are specifically and covalently binding to lysine residues of substrate proteins. Through SUMOylation, the physiological functions and pathological processes of cells are well controlled and balanced, and its abnormal activation has been reported in various tumors. Therefore, SUMOylation has been a potential target for anti-tumor drug development. In this review, we summarize recent advances on development of inhibitors targeting SUMOylation pathway and their antitumor properties.

Objective To establish and evaluate a universal real-time fluorescent quantitative PCR(qPCR)method for identifying and quantifying three human parvovirus B 19 ( B19V) genotypes.Methods Firstly, following a bioinformatic analysis of a subset of B19V genomic sequences available in the NCBI nucleotide database ,representative of genotypes 1 to 3,a set of suitable universal primers and TaqMan probes was designed from the NS 1 gene of B19V.Aplasmid was used as a quantitative standard that contained the identical sequence of the B 19 target sequence .An internal control ( IC ) was included to prevent false negative results .Then,serial 1-log dilutions of quantitative standards were prepared and used in the qPCR assays for generation of a standard curve .Finally,the specificity,sensitivity and reproducibility of the assay were assessed.Results A linear relationship of the real-time PCR method for detecting B19V from 1 ×109copies/μl to 1 ×103 copies/μl was observed .The developed qPCR protocols allowed for the detection of genotypes 1 to 3 with a limit of detection ( LOD) of 10 copies/μl.Furthermore, the assay did not amplify other blood-borne viruses.The inter-and intra-assay variability analyses showed good reproducibility of the assay .Conclusion A universal real-time qPCR method for the detection of B19V DNA is established,which will facilitate the diagnosis of B19V infections and the screening of blood and plasma-derived products , thereby improving the viral safety of transfusion and plasma-derived products .

Objective To investigate the expression of FTO in gastric cancer tissues and the functional significance of FTO in MGC-803 cell line.Methods The FTO mRNA was detected by RT-qPCR in 54 cases of gastric cancer samples and their paired adjacent normal control tissues.The effect of FTO overexpression in MGC-803 on cell proliferation,cell migration and invasion were detected by CCK-8,wound heal and ranswell assays,respectively.Results The expression of FTO mRNA was significantly lower than that of adjacent tissues(P<O.05).Furthermore,overexpression of FTO in MGC-803 cells inhibited cell proliferation,cell migration and invasion.Conclusions FTO is low expressed in gastric cancer tissues and inhibits gastric cancer cell line MGC-803 proliferation,migration and invasion.FTO is closely associated with the development of gastric cancer.

AIM: To observe the effects of high-dose hepatitis B surface antigen (HBsAg) vaccine on cellular immune response in BALB/C mice. METHODS: The mice were immunilized separately with low-dose and high-dose HBsAg vaccine by intramuscular injection two times. The specific proliferative activities of T lymphocytes were measured by [ 3H]-TdR incorporation assay. IL-2 as well as IFN-? levels in the culture supernatant of T cells and anti-HBs IgG2a lever in sera were detected by enzyme-linked immunoabsorbent assay. RESULTS: After first vaccination with high-dose HBsAg, the proliferative activities of T cells in the experimental group were significantly stronger, both levels of IL-2 and IFN-? were markedly higher than that in the control group and the percentage of mice to produce serum anti-HBs IgG2a was significantly higher compared to that of mice immunilized by low-dose HBsAg. All data in experimental groups were further increased after second dose of vaccine. CONCLUSION: Vaccination of mice with high-dose HBsAg can induce cellular immune responses tended to Th1(T helper 1 subset) response.

Objective To explore the relationship between the endovascular aortic repair (EVAR)in patients with abdominal aortic aneurysm (AAA) and postoperative systemic inflammatory response syndrome (SIRS).Methods In this study,93 AAA patients undergoing EVAR were enrolled.Analysis was performed to evaluate the incidence of SIRS during peri-operation period.Logistic multiple regression analysis was performed to determine the parameters predicting SIRS.Results The incidence of SIRS was 58.1%.Aneurysm size,mural thrombus,iliac artery lesion,number of stent,operating time,volume of contrast agent,blood loss and length of stay were all significantly correlated with SIRS (P < 0.05).In a logistic regression model,history of kidney disease or operation,aneurysm size,ruptured aneurysm and number of stents were strongly and independently associated with SIRS.Conclusions SIRS is common in AAA patients after EVAR.Optimizing treatment strategies avoiding risk factors for SIRS benefits AAA patients.

Objective To probe into the reasons for and results of remedial surgical therapy in thoracic aortic dissection patients after first endovascalar repair.Methods From July 2000 to December 2012,12 cases received second interventional surgery.The average time from second therapy to first surgery was ( 14 ± 11 ) months.Main reasons for second endovascular therapy were sustained type Ⅰ endoleak at proximal landing zone and type A dissection caused by retrograde tear.Therapies included hybrid operations in 8 cases and absnlute endovascular therapy in 4 cases.Results The 30 day mortality after the second intervention was 5.6% ( 1/12),total mortality rate was 16.7% (2/12).In 7 cases with endoleak,small endoleak remained after remedial therapy (57.1% ) in 4 cases.Among 4 cases with secondary type A aortic dissection,successful staged hybrid operation with mid-sternal thoracotomy was adopted in 3 cases,one died of pulmonary emtbolism during follow-up period,1 case with Bebcet disease still had proximal type Ⅰ endoleak after second hybrid operation,and died from tear of aorta.Conclusions Endoleak and secondary type A aortic dissection are the main cause necessitating second intervention after primary endovascular therapy for thoracic aortic dissection.Hybrid operation remains the best choice to treat postoperative complications after endovascular therapy for thoracic aortic dissection.
