Objective:The transjugular or transfemoral approach is used as a common method for hepatic venous pressure gradient (HVPG) measurement in current practice. This study aims to confirm the safety and effectiveness of measuring HVPG via the forearm venous approach.Methods:Prospective recruitment was conducted for patients with cirrhosis who underwent HVPG measurement via the forearm venous approach at six hospitals in China and Japan from September 2020 to December 2020. Patients' clinical baseline information and HVPG measurement data were collected. The right median cubital vein or basilic vein approach for all enrolled patients was selected. The HVPG standard process was used to measure pressure. Research data were analyzed using SPSS 22.0 statistical software. Quantitative data were used to represent medians (interquartile ranges), while qualitative data were used to represent frequency and rates. The correlation between two sets of data was analyzed using Pearson correlation analysis.Results:A total of 43 cases were enrolled in this study. Of these, 41 (95.3%) successfully underwent HVPG measurement via the forearm venous approach. None of the patients had any serious complications. The median operation time for HVPG detection via forearm vein was 18.0 minutes (12.3~38.8 minutes). This study confirmed that HVPG was positively closely related to Child-Pugh score ( r = 0.47, P = 0.002), albumin-bilirubin score ( r = 0.37, P = 0.001), Lok index ( r = 0.36, P = 0.02), liver stiffness ( r = 0.58, P = 0.01), and spleen stiffness ( r = 0.77, P = 0.01), while negatively correlated with albumin ( r = -0.42, P = 0.006). Conclusion:The results of this multi-centre retrospective study suggest that HVPG measurement via the forearm venous approach is safe and feasible.

Objective To evaluate the role of preoperative serological indexes in predicting long-term survival and tumor recurrence of hepatocellular carcinoma (HCC) patients after liver transplantation, aiming to explore its significance in expanding the Milan criteria. Methods Clinical data of 669 recipients undergoing liver transplantation for HCC were retrospectively analyzed. The optimal cut-off value was calculated by the receiver operating characteristic (ROC) curve. The risk factors affecting the overall survival and recurrence-free survival rates of HCC patients after liver transplantation were identified by univariate and multivariate regression analyses. The correlation between preoperative serum liver enzymes and pathological characteristics in HCC patients was analyzed. The predictive values of alpha-fetoprotein (AFP) combined with γ -glutamyl transferase (GGT) and different liver transplant criteria for the survival and recurrence of HCC patients after liver transplantation were compared. Results Exceeded Milan criteria, total tumor diameter (TTD) > 8 cm, AFP > 200 ng/mL and GGT > 84 U/L were the independent risk factors for the overall survival and recurrence-free survival rates of HCC patients after liver transplantation (all

Objective To study the expression of SGK1 in T lymphocytes from pediatric asthma,and the effect of SGK1 on the differentiation of T cells,also to explore the function of SGK1 regulating the differen-tiation of T subset in pediatric asthma. Methods Twenty-eight children with asthma were recruited in Xi′an children′s hospital and divided into moderate group and severe group according to diagnostic guideline of asth-ma. The serum levels of IL-4,IL-13 and IL-17A were analyzed by ELISA. The CD4 +T cells from PBMC and na?ve T cells were selected using magnetic beads. Na?ve T cells were differentiated in vitro under cytokines. SGK1 expression were analyzed with Real-time PCR. The ability of Th2 and Th17 on secreting IL-4 and IL-17A were detected after SGK1 was inhibited by siRNA. In vivo,shRNA-SGK1 Na?ve T cells were transferred into the mice asthma models by intravenous injection. The airway inflammation were observed in shRNA-SGK1 Na?ve T models. Results Compared with healthy children,the serum levels of IL-4、IL-13 and IL-17A increased signifi-cantly in the children with asthma. Importantly,the levels of these three cytokines were much higher with the de-velopment of asthma. SGK1 were up-regulated remarkably in CD4 +T cells from the children with asthma and were positively correlated with IL-13 and IL-17A. Besides,SGK1 expression increased in the differentiated Th2 and Th17 in vitro,but had no change in the differentiated Th1. The levels of IL-4 and IL-17A associated with Th2 and Th17 decreased after SGK1 was inhibited by siRNA. Similarly,In vivo,the serum levels of IL-13 and IL-17A and airway inflammation were reduced in shRNA-SGK1 Na?ve T models. Conclusion The over-expres-sion of SGK1 in pediatric asthma enhances the asthma progress by promoting the differentiation of T subsets.

OBJECTIVETo investigate the effect and explore its possible mechanisms of epidermal growth factor receptor(EGFR) expression in macrophages on the anti-cancer effect of berberine (BER) on the growth of colorectal cancer.
METHODSMice with EGFR gene defects in macrophages (Egfr(fl/fl) LysM-Cre) and with EGFR gene expression in macrophages (LysM-Cre) (control group) were treated with azoxymethane (AOM) to establish colorectal tumor models. These models were treated with or without berberine (BER) intervention. The number of colorectal tumors and the gut length in the two groups were measured. The proliferation of tumor cells was detected by Ki-67 immunohistochemistry and apoptosis was detected by annexin V-FITC fluorescence labeling. Western blot was used to detect the expression of cleaved-caspase-3 protein.
RESULTSAfter treated with AOM, the colorectal tumor number was 10.26 ± 1.43 in the LysM-Cre group and 7.62 ± 1.05 in the Egfr(fl/fl) LysM-Cre group, showing a significant difference (P = 0.021). The gut length was (6.04 ± 1.06) cm in the LysM-Cre group and (6.39 ± 0.92) cm in the gfrfl/flLysM-Cre group, with a non-significant difference between the two groups (P = 0.075). After treated with AOM plus BER intervention, the colorectal tumor number of the LysM-Cre group was 8.35 ± 1.22 and that in the Egfr(fl/fl) LysM-Cre group was 2.66 ± 0.38, showing a very significant difference between the two groups (P = 0.006). The gut length of the LysM-Cre group was (7.34 ± 1.16) cm and that of the Egfr(fl/fl) LysM-Cre group was (10.01 ± 1.72) cm (P = 0.028). After treated with AOM, the ratio of Ki-67-positive tumor cells in the LysM-Cre group was (78.31 ± 3.43)% and that in the Egfr(fl/fl) LysM-Cre group was (75.85 ± 2.92)% (P = 0.282). After AOM plus BER treatment, the ratio of Ki-67-positive tumor cells in the LysM-Cre group was (42.43 ± 3.09)% and that in the Egfr(fl/fl) LysM-Cre group was significantly lower (29.65 ± 2.47)% (P = 0.018). The ratio of annexin V-positive tumor cells was (0.95 ± 0.13)% in the LysM-Cre group, not significantly different from (1.13 ± 0.16)% in the Egfr(fl/fl) LysM-Cre group (P = 0.175). After AOM plus BER treatment, the ratio of annexin V-positive tumor cells in the LysM-Cre group was (32.10 ± 1.97)%, significantly lower than the (47.08 ± 2.83)% in the Egfr(fl/fl) LysM-Cre group (P = 0.010). The level of cleaved-caspase-3 protein expression was 235.92 ± 19.73 in the Egfr(fl/fl) LysM-Cre group, significantly higher than the 119.71 ± 12.87 in the LysM-Cre group (P = 0.012).
CONCLUSIONSThe growth of colorectal cancer cells in mice can be inhibited by BER treatment, and this anti-cancer effect of BER can be further enhanced by EGFR gene knockout in macrophages. The mechanisms may be related to the inhibition of proliferation and promotion of apoptosis in colorectal cancer cells.

This study was aimed to design the distal radial anatomic splint which was more in line with the human anatomy and treatment characteristics using the computer design software 3D-MAX. According to ergonomic design principles, the forearm and wrist plaster splint were selected from volunteer models. Then, data of the plaster was measured and input into the computer for the design of the three-dimensional model of distal radial anatomic splint with 3D-MAX software. Finally, the blueprint was drawn for the factory to make the distal radial anatomic splint. The results showed that the distal radial anatomic splint was more in line with human anatomy, which did not require shaping in clinical using. It did not affect the biomechanical properties. And the patients never complain the squeez-ing discomfort of the splint. It was concluded that the three-dimensional model of the distal radial anatomic splint, which designed with 3D-MAX software, provided key parameters of the important part of the distal radial anatomic splint. Therefore, the produced splint was more in accordance with the human anatomy and the clinic treatment re-quirements. It avoided the loss of biomechanical properties after shaping, which was more convenient and effective in the clinical using. Its clinical promotion has a broad prospect.
