Currently,XB130 as a newly discovered characterized adaptor protein ,it has been implicated as a substrate and regulator of many intracellular signal transduction ,such as FAK/SRC,PI3K/Akt and MEK-ERK signaling and so on.It has been found that XB130 is high expression in many cell lines ,for instance thyroid carcinoma,osteosarcoma,gastric cancer,esophageal cancer and breast cancer etc .The mechanism of XB130 in tumor is becoming increasingly attention .XB130 is recently attributed to be a new oncogene ,and plays important roles in cell pro -liferation,cell survival and tumorigenesis .A deeper understanding of these mechanisms may lead to the discovery of XB130 as an important mediator in tumor development and as a novel therapeutic target for cancer.

Objective:To study the effect of ulinastatin combined with early enteral nutrition on severe acute pancreatitis and its effect on nuclear factor-κB(NF-κB) and Toll-like receptor 4 (TLR4).Methods:Ninety severe acute pancreatitis patients who were treated in Central Hospital of Lijin County from January 2016 to January 2020 were selected and were divided into U+EEN group (ulinastatin combined with early enteral nutrition therapy) and EEN group (early enteral nutrition therapy) by random number table method, with 45 patients in each group. Curative effect, complications, nutritional indicators, immunoglobulins and inflammatory factors were detected and compared with analysis of variance. Western blot was used to detect the expression of NF-κB and TLR4 in pancreatic tissue in two groups.Results:The hospitalization time, ICU admission time, intestinal ventilation time, hospitalization costs and organ failure rate, pancreatic cysts, diabetes, chronic pancreatitis, incidence of sepsis in U + EEN group were lower than those in EEN group: (2.1 ± 0.4) months vs. (2.4 ± 0.6) months, (16.9 ± 2.1) d vs. (21.7 ± 2.8) d, (23.7 ± 3.8) d vs. (27.4 ± 4.1) d, (11.4 ± 1.5) thousand Yuan vs. (14.1 ± 2.1) thousand Yuan and 8.9%(4/45) vs. 20.0%(9/45), 13.3%(6/45) vs. 28.9%(13/45), 11.1%(5/45) vs. 24.4%(11/45), 8.9%(4/45) vs. 26.7%(12/45), 6.7%(3/45) vs. 22.2%(10/45), and the differences were statistically significant ( P<0.05). The levels of prealbumin (PA), albumin (ALB) and total protein (TP) after treatment in U + EEN group were higher than those in EEN group: (107.4 ± 6.5) mg/L vs. (102.8 ± 4.7) mg/L, (46.1 ± 3.5) g/L vs. (43.4 ± 2.8) g/L, (55.9 ± 3.4) g/L vs. (53.7 ± 3.1) g/L, and the differences were statistically significant ( P<0.05). The levels of IgG, IgA, IgM after treatment in U+EEN group were higher than those in EEN group: (10.5 ± 1.6) g/L vs. (9.5 ± 1.3) g/L, (8.9 ± 1.4) mg/L vs. (8.3 ± 1.2) mg/L, (60.5 ± 3.6) mg/L vs. (55.9 ± 3.4) mg/L, the levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-8 in U+EEN group were lower than those in EEN group: (25.1 ± 2.9) mg/L vs. (30.6 ± 4.1) mg/L, (20.1 ± 1.9) mg/L vs. (24.6 ± 1.5) mg/L, (17.8 ± 1.9) mg/L vs. (20.1 ± 2.3) mg/L, and the differences were statistically significant ( P<0.05). The expressions of NF-κB and TLR4 protein in pancreatic tissue of patients in U + EEN group were significantly lower than those in EEN group (0.3 ± 0.2 vs. 0.5 ± 0.2, 0.2 ± 0.1 vs. 0.5 ± 0.1, P<0.05). Conclusions:Ulinastatin combined with early enteral nutrition can significantly improve the nutritional status and immune function and improve the prognosis of patients with severe acute pancreatitis, which may be related to ulinastatin′s reduction effect of NF-κB and TLR4′s expressions.

Background and purpose: Urokinase-type plasminogen activator receptor is related to invasion and metastasis of tumor. Inhibition of uPAR expression in tumor cells results in reducing its metastasis. This study was aimed to construct an expression vector with short hairpin RNA (shRNA) of uPAR, which could pave the way for RNAi-mediated tongue squamous cell carcinoma therapy. Methods: Genome sequences of uPAR gene were retrieved from Genhank and cDNA was designed to code expression of shRNA for uPAR gene. The cDNA was synthesized and inserted into the eukaryotic expression vector pWH1, and the recombinant pWH1-uPAR expression vector was identified by enzyme cutting method. Then, pWH1-uPAR expression vector was transfected into tongue squamous cell carcinoma Ts cells by Lipofectomine 2000. At last, the expression of uPAR in Ts cells transfected with pWH1-uPAR expression vector was observed by RT-PCR, immunocytochemistry staining and Western blot. MTT assay was performed to measure the proliferation of Ts cell. Results: The uPAR shRNA eukaryotic expression vector was successfully constructed. Compared with Ts cells and Ts cells transfected with plasmid pWH1, the Ts cells transfected with pWHI-uPAR expression vector showed a lower mRNA and protein expression of uPAR. The inhibition rate of proliferation was 32.9% of Ts cells by transfected with pWHl- uPAR. Conclusion: The constructed uPAR shR.NA expression vector could inhibit the expression of uPAR in tongue squamous cell carcinoma, which may be helpful for further research on the function of uPAR and provide effective methods for therapy of tongue squamous cell carcinoma.

Objective To investigate the epidemic characteristics of prostate cancer in China. Methods The population-based cancer registration data between year 1988 and 2002 were collected from 30 cancer registries in China. The data from 11 registries with continuous record were analyzed using the software Joinpoint Regression Program 3.3.1, and the incidence of bladder cancer among 3 different periods (1988-1992, 1993-1997 and 1998-2002) were compared. Results The inci-dence of prostate cancer was 1.96, 3.09, 4. 36 per 100 000 during 1998-1992, 1993-1997 and 1998-2002, respectively. The up-trend of prostate cancer incidence was statistically significant, how-ever it is still lower in China compared with other parts of the world from 1993 to 1997. Conclusions The incidence of prostate cancer in China showed a significant upward trend year by year, and prostate cancer might be one of major cancer in China. We should pay attention to it.
