Chemokines participate in many biological functions including immune inflammatory response,various metabolic reactions and damage stress response.Meanwhile,they also play a crucial role in the process of tumor progression including regulating tumor proliferation,invasion and metastasis,and mediating immune cells infiltration and angiogenesis in tumor tissue as well as the tolerance to antitumor treatment.Pancreatic cancer is one of the highly malignant digestive system neoplasms with relatively high risk of early local invasion and distant metastasis,resulting in high mortality.At present,the specific mechanism of the development of pancreatic cancer has not been clarified yet.In recent years,the role of chemokine CXC (chemokine subfamily) and its receptor CXCR (CXC chemokine receptors) in pancreatic cancer has become a hot research topic and great progress has been made in this field.This paper overviewed the recent research advance on the functions of chemokine CXC and their receptors in pancreatic cancer.

Objective To evaluate the effect of immune fluorescence chromatography on glycosylated hemoglobin (HbA1c). Methods The precision of immune fluorescence chromatography was evaluated with samples of 6.0% and 8.0% fixed value. Group of High performance liquid chromatography (HPLC) as control, HbA1c for 200 samples of EDTA-K2 anti-coagulated whole blood were detected by immune fluorescence chromatography to synchronous blinded trial. Results As to the precise of immune fluorescence chromatography in the samples of 6% and 8%, values of coefficient of variation were 5.1% and 5.3%, respectively. The linear regression equation of immune fluorescence chromatography and HPLC was Y=-0.110+1.021X and the correlation coefficient was 0.982. 6.0% and 8.0% as the cut-off value, kappa values were 0.950 (P < 0.001) and 0.922 (P < 0.001), respectively. Conclusion Immune fluorescence chromatography and HPLC is consistent with detection of HbA1c, which can be used for clinical detection of HbA1c.

Objective Hepatocellular carcinoma with bile duct tumor thrombus (BDTT) is rare,and surgical treatment is currently considered as the most effective treatment.Whether resectional surgery should be carried out on these patients remains controversial.Therefore,this Meta-analysis aimed to find out the long-term survival after resectional surgical treatment.Methods We conducted a literature search on PubMed,Embase and Web of Science from inception to September 2016.11 studies were included which involved 5295 patients.Each study was evaluated using the Newcastle-Ottawa Scale.The pooled effect was calculated and the associations between BDTT and overall survival (OS) or disease-free survival (DFS)were reevaluated using Meta-analysis with hazard ratio (HR) and 95％ confidence interval (CI).Results The HR for OS and DFS was 2.34 and 1.81,the 95％ CI were 1.26 ～ 4.36 and 1.17 ～ 2.78,respectively.Conclusion HCC patients with BDTT had a bad prognosis after hepatic resection or liver transplantation.

Objective To investigate the expression and clinical significance of ROC1 in ovarian cancer tissues ,to provide new ideas for the gene therapy of ovarian cancer .Methods 261 women with ovarian cancer underwent resection from December 2005 to December 2007 in the Affiliated Hospital of Zunyi Medical College and with 5 years follow-up were enrolled .ROC1 mRNA transcription and protein expression level of ovarian cancer tissue and surrounding normal tissue were tested ,and later the correla-tion between the results and patient′s prognosis was statistically analyzed .Results ROC1 in ovarian cancer tissue was over-ex-pressed ,but almost no expression in surrounding normal ovarian carcinoma ;ROC1 expression levels had a negative correlation with the survival rate of the patients .Conclusion ROC1 in ovarian cancer tissue was over-expressed ,but almost no expression in sur-rounding normal ovarian carcinoma ;ROC1 expression levels had a negative correlation with the survival rate of the patients .

This article was aimed to propose and develop traditional Chinese medicine (TCM) health engineering, using modern science and technology, in order to carry out the detection research which reflected TCM features of human functional state. It was an important way to achieve TCM diagnosis and the objective evaluation on therapeutic effects of TCM. The combination of TCM health engineering with information technology, and the formation of TCM functional state intelligent identification system, as well as the extension into the Health Internet of Things (HIT) could provide more accurate and convenient services for human healthcare in the age of big health. And identification on TCM syndromes was the core to achieve this goal. Using characterization data on TCM syndromes could realize the data processing between TCM syndrome and prescription through intelligent computing, in order to form the TCM syndrome differentiation and treatment intelligent system. It had great significance in the promotion of TCM health project.

Objective To explore the significance of changes of matrix metalloproteinase-9 (MMP-9),interleukin-6 (IL-6),and tumor necrosis factor-alpha (TNF-oα) protein level in the cerebrospinal fluid (CSF) of children with viral encephalitis (VE).Methods The concentration of neuron-specific enolase (NSE),structural proteins 100B (S100B),and MMP-9,IL-6,TNF-α in the CSF of VE children were detected by an enzyme linked immunosorbent assay,and the correlations of them were analyzed.Results NSE,S100B,MMP-9,IL-6,TNF-α protein expression could be found significantly higher than those in the control group,and there were significant differences according to statistics expression trends(all P ＜0.05).The NSE protein expression was significantly positive related with S100B in the VE group (r =0.467,P =0.009),and the concentration was markedly negative related with the duration of viral encephalitis (r =-0.472,P =0.008).MMP-9,IL-6 protein expression were significantly positive related with NSE,S100B respectively (r =0.698,P =0.00 ; r =0.559,P =0.00 ; r =0.812,P =0.00 ; r =0.664,P =0.00).TNF-α protein expression was positive related with CSF S100B(r =0.363,P =0.049),but there was no correlation between TNF-α and NSE (r =0.245,P =0.193).Conclusions The neurons and the neuroglial cells are damaged in the viral encephalitis children.MMP-9,IL-6,TNF-α protein may participate in the pathological damage process of nerve cells in VE children in different degrees.

Objective To investigate the safety, feasibility and results of laparoscopic assisted distal radical gastrectomy for gastric cancer. Methods Twenty-three cases of gastric cancer were subjected to laparoscopic assisted distal radical gastrectomy, D_(1+α)/D_(1+β) lymphadenectomy on 3 cases and D_2 lymphadenectomy on 20 cases. All cases received Billroth I reconstruction. Results Laparoscopic assisted distal radical gastrectomy was carried out in all cases successfully. The mean operative time was (205 ±38 )min, mean blood loss was (105 ± 66) ml and mean number of lymph nodes dissected was 19.7 ± 6.2 each case. The mean postoperative time of recovery of bowel function was (3.5 ±1.2) d,mean postoperative time of liquid intake was (4.9 ±0.9) d and mean hospitalization was (10.2 ± 2.7) d. No postoperative death or anastomotic fistula was found. Postoperative upper gastrointestinal bleeding occurred in 1 case and was cured by conservative treatment. Follow-up for 1-12 months revealed no recurrence or metastasis. Conclusions Laparoscopic assisted distal radical gastrectomy is a safe and feasible procedure with satisfactory short-term outcomes.Moreover,the short-term outcomes may be improved if the patients are treated under the notion of fast track surgery.
