Heterogeneous-nuclear ribonucleoproteins A1 (hnRNP A1) is one of the important members of hnRNPs family. The function of hnRNP A1 is closely related to RNA transcription, mRNA translation, splicing of splicing sites, splicing site selection, pre-RNA maturation and degradation, cell proliferation and transformation. Overexpression of hnRNP A1 in various types of digestive system tumors is associated with poor prognosis and may serve as an early biomarker for cancer. This article reviews the recent advances in the development of hnRNP A1 and characterizes their roles in cellular and gene expression and in the development of human tumors, highlighting that hnRNP A1 is likely to be an important indicator for tumor prognosis and a potential drug target for the treatment.

Objective To investigate whether Ki-67 and DNA topoisomerase Ⅱ α (Topo Ⅱ α) are effective prognostic markers in patients with primary hepatocellular carcinoma (HCC) after liver transplantation.Methods This retrospective cohort study included 105 patients with HCC who underwent liver transplantation in a single center from 2001 to 2012.The demographic features,clinicopathological data,expressions of Topo I c and Ki-67 as detected by immunohistochemistry.The long-term survival and the potential prognostic factors,together with standard histologic parameters,were analyzed by univariate and multivariate analyses.Results A positive correlation was found between Topo II α and Ki-67 levels in HCC (r ＝ 0.469,P ＜ 0.01).Multivariate analyses showed that Ki-67 was an independent prognostic risk factor of recurrencefree survival (HR ＝ 2.296,P ＜ 0.05).The 5-year overall survival rate was related to tumor size (HR ＝ 1.743,P ＜ 0.05),AFP (HR ＝ 2.291,P ＜ 0.05),histological grade (HR ＝ 0.283,P ＜ 0.01),and high expressions of Ki-67 (HR ＝ 1.977,P ＜ 0.05) and Topo Ⅱ α levels (HR ＝ 1.883,P ＜ 0.05).The KaplanMeier analysis showed that there was a significant difference in the 5-year recurrence-free survival rate (40.4％ vs.57.6％) between patients with high and low expressions of Ki-67,which were significantly lower in the high Topo Ⅱ α expression patients (13.5％ vs.63.8％) (P ＜0.01).The 5-year overall survival rates were significantly lower in the high Ki-67 expression patients (12.7％ vs.61.1％,P ＜0.01) when compared with the low Ki-67 expression patients,which were significantly lower in the high Topo Ⅱ α-and Ki-67 expression patients (10.7％ vs.54.5％,P ＜0.01) than the low Topo Ⅱ α-or Ki-67 patients.Conclusions Ki-67 was associated with recurrence and metastasis in patients with primary hepatic carcinoma after liver transplantation.High expression of both Ki-67 and Topo Ⅱ α were associated with poor prognosis in these patients.

Objective To observe the effects of buccal acupuncture therapy and body acupuncture therapy on plasma metabolomites of rheumatoid arthritis rabbits model; To search for the metabolites related to the mechanism of buccal acupuncture and body acupuncture. Methods Sixteen rabbits were made into rheumatoid arthritis models by complete freund's adjuvant before the treatment. The buccal acupuncture group was treated by buccal acupuncture on the knee acupoint; 13 mm × 0.32 mm needle straight 0.2–0.5 mm, twist the main points of stimulation 15 s, once a day. The body acupuncture group was treated by body acupuncture on the Xiyan and Zusanli acupoints; with 13 mm × 0.32 mm needle straight 2–3 mm, every 5 min each time, twisting needle method, 100 times/min for 15 s, once a day. After the continuous treatment for 5 days, UPLC-QTOF/MS was applied to test metabolite from the plasma sample of all groups. Similarity analysis, hierarchical cluster analysis (HCA), principal component analysis (PCA), orthogonal partial least squares-discriminant analysis (OPLS-DA) were applied in this research; meanwhile load analysis method was used to identify the meaningful metabolites. Results The similarity analysis, HCA and PCA all showed the significant difference of endogenous metabolites in plasma samples among the buccal acupuncture group, the body acupuncture, the model group and the blank group. The 4 groups of different plasma sample metabolite were completely separated in three dimensions by OPLS-DA and all the samples were gathered respectively. The load analysis indicated that there were 19 kinds of endogenous metabolites which showed the significant differences between buccal acupuncture group and model group, and also happened between the body acupuncture group and the model group; N-cetyl-L-phenylalanine and 2-phenyl propionate in metabolism of phenylalanine and tyrosine decreased significantly in the buccal acupuncture group while significantly increased in the body acupuncture group. Conclusion There are relative similarity on the mechanism of treating rheumatoid arthritis between buccal acupuncture and body acupuncture. However, N-acetyl-L-phenylalanine and 2-phenyl propionate, as the main potential biomarkers of the difference, indicate that the dissimilarity can be significant.

Objective Our objective was to design a new type of bedpan (inflatable, bed urinal) and compare its effect with common bedpan. Methods We divided 144 patients with bone fracture and lying in bed into the test group and the control group with 72 cases in each group from May 2006 to February 2007. Inflatable bed urinals were used in the test group and common bedpans were used in the control group. The pain alleviation, comfort degree, staining of bed sheet and skin injury were observed and evaluated in each group. Results Application of inflatable bed urinal was superior to common bedpan in the following aspects: alleviation of pain, comfort degree, staining of bed sheets and skin injury. Conclusions Adoption of inflatable bed urinal could alleviate pain, prevent the incidence of complication and reduce the workload of nurses.

Objective To study the expressions of HnRNPA1 in patients with recurrent or metastatic hepatocellular carcinoma (HCC) after liver transplantation.Methods The expressions of HnRNPA1 protein in pericarcinoma and normal liver tissues were detected using Western blot analysis in 16 patients with HCC.Immunohistochemical analysis was done in 141 patients with HCC.All these patients underwent liver transplantation.The relationship between the expressions of HnRNPA1 with recurrent and metastatic HCC were analyzed.Results The positive expression rate of HnRNPA1 protein in the HCC tissues (75.0％,12/16) was significantly higher than that in the pericarcinoma tissues (18.8％,3/16) (P ＜ 0.01).The expression of HnRNPA1 was positively correlated with tumor size,TNM type,vascular invasion and tumor encapsulation (P ＜ 0.01).Tumor recurrence in the HnRNPA1 high expression group was significantly higher than that in the HnRNPA1 low expression group (x2 =15.577,P ＜ 0.01).The survival rate was significantly lower in the high HnRNPA1 expression than that in the low expression group (x2 =6.309,P ＜0.05).Conclusion The expression of HnRNPA1 protein was a marker which predicted HCC recurrence or metastasis in patients after liver transplantation.

Objective To investigate the biliary complications and recovery of liver function after liver transplantation from citizen's deceased donors (DCD) versus standard criteria donors (SCD).Method The clinical data of 269 patients who underwent orthotopic liver transplantation from January 2009 to December 2016 at the Fuzhou General Hospital were collected.197 livers were from SCD and 72 from DCD.Propensity score matching (PSM) was used to compare the biliary complications and recovery of liver function after liver transplantation in the two groups.Results PSM matched 61 pairs of patients.There were 10 (16.4％) and 8 (13.1％) biliary complications in the DCD and the SCD groups,respectively,with no significant difference between them (P ＞ 0.05).The recovery of liver function was significantly delayed in the DCD group when compared with the SCD group.The levels of ALT,AST,GGT and AKP in the DCD group were significant different on the postoperative first,third,fifth,seventh and fourteenth day (P ＜ 0.05).At 30 days after surgery,there was no significant difference in liver function between the two groups.Conclusions Liver grafts from DCD had a significant impact on the recovery of liver function.When compared with the SCD group,the DCD group recovered significantly slower in liver function.There was no significant increase in the incidence of biliary complications.

Objective To investigate the expression of long-chain non-coding RNA gastric cancer high expression transcription factor 1 (GHET1) in hepatocellular carcinoma (HCC) and the correlation with prognosis,cell proliferation,migration and invasion.Methods 20 HCC patients who underwent surgery from Fuzhou General Hospital of Chinese People's Liberation Army from March to May 2016 were included.The HCC tissue and adjacent normal tissue of 182 patients from June 2012 to December 2013 were retrospectively collected.According to the median value of GHET1 expression,it was divided into GHET1 high expression group and low expression group,91 cases each.Huh7 and HepG2 cells were divided into:blank control group (Con) with serum-free medium,siRNA-GHET1 group transfected with siRNA-GHET1,and negative control group (siRNA-NC) transfected with negative control sequence.The expression of GHET1 was detected by real-time fluorescence quantitative polymerase chain reaction,and the effect of GHET1 on HCC cells was analyzed by CCK-8,Transwell assay and Western blot.Results Compared with adjacent normal tissue,the relative expression of GHET1 mRNA in HCC tissues was significantly increased.Compared with LO2 cells,the mRNA expression of GHET1 in Huh7 and HepG2 cells was higher (P＜0.05).The GHET1 high expression group had tumor＞5 cm,vascular invasion,AFP＞400 μg/L,Edmonson grade Ⅰ,and the tumor-free ratio was lower in the expression group (P＜0.05).Survival analysis showed that HCC patients with high GHET1 expression had a poorer prognosis than patients with low expression.Multivariate Cox regression analysis showed that high expressed GHET1,vascular invasion (HR=2.067,95％ CI:1.350 to 3.162),and without tumor capsule are independent predictors of recurrence in HCC patients.After transfection with Huh7 and HepG2 cells,the proliferation of siRNA-GHET1 group was significantly decreased comparing with Con and siRNA-NC groups.Compared with siRNA-NC group,the migration and invasion ability of siRNA-GHET1 group decreased,and E-cadherin expression increased.The expression of fibronectin and vimentin decreased,and the difference was statistically significant (P＜0.05).Conclusions The expression of GHET1 in HCC tissue is higher comparing with normal tissue,which increases the proliferation,migration and invasion of hepatoma cells.It is an independent predictor of prognosis in HCC patients and a potential target for clinical treatment.

Objective:To investigate the predictive effect of neutrophil to lymphocyte ratio (NLR) for recurrence-free survival after liver transplantation in hepatocellular carcinoma (HCC) patients.Methods:The clinical data of 84 HCC patients who underwent liver transplantation in the 900th Hospital of the Joint Logistics Team, PLA, from January 2012 to December 2019 were included in this retrospective analysis. There were 73 males and 11 females, with an average age of 51 years. Univariate and multivariate Cox regression analyses were performed. The distinguishing ability of NLR for predicting recurrence-free survival in patients with HCC after liver transplantation was analyzed using the receiver operating characteristic (ROC) curvee. The two groups were generated according with the cut-off value, and the recurrence-free survival time to make the Kaplan-Meier survival curve.Results:The area under the ROC curve of NLR for predicting recurrence-free survival after liver transplantation in patients with HCC was 0.683, Yoden index was 0.319, and the optimal threshold was 3.2.Univariate analysis showed that maximum tumor diameter, number of tumors, Milan criteria, and NLR were associated with recurrence-free survival after liver transplantation in patients with HCC (all P<0.05). Multivariate analysis showed that maximum tumor diameter ( HR=2.412, 95% CI: 1.277-4.555), number of tumors ≥3 ( HR=5.595, 95% CI: 2.023-17.531) and NLR≥3.2 ( HR=2.891, 95% CI: 1.348-6.204) were independent risk factors for recurrence-free survival of HCC patients prediction after liver transplantation (all P<0.05). The 1-year recurrence-free survival rate was 78% in the NLR<3.2 group ( n=61), which was superior to 58% in the NLR≥3.2 group ( n=23), and the difference was statistically significant ( P<0.05). Conclusion:Tumor diameter, number of tumors and NLR are risk factors affecting the prognosis of liver transplantation in patients with HCC, and high serum NLR may indicate recurrence-free survival in patients with HCC after liver transplantation.
