Objective:To evaluate the effect of intraoperative intravenous infusion of lidocaine on the occurrence of postoperative acute kidney injury (AKI) in patients with enterogenic sepsis.Methods:In this prospective randomized controlled trial, 80 patients of either sex with enterogenic sepsis, aged ≥18 yr, with a body mass index of 18-30 kg/m 2, who underwent emergency laparotomy under general anesthesia at the People′s Hospital of Xinjiang Uygur Autonomous Region between January and December 2024, were assigned to 2 groups ( n=40 each) using a table of random numbers: control group (group C) and lidocaine group (group L). Immediately after anesthetic induction, lidocaine was intravenously injected as a loading dose of 1 mg/kg, followed by a continuous infusion at 1.5 mg·kg -1·h -1 until the end of surgery in group L, while group C received the equal volume of normal saline infused at the same rate instead. The occurrence of AKI was recorded within 7 days after operation. The in-hospital death, length of intensive care unit stay, and duration of postoperative mechanical ventilation were recorded. Peripheral blood samples were collected on the day of surgery (T 0) and on postoperative days 1, 2 and 7 (T 1-3) to measure the concentrations of serum creatinine, urea, lactate, procalcitonin, interleukin-6, and C-reactive protein and the difference at each time point after operation relative to the baseline value at T 0 was calculated. Results:Compared with group C, the incidence of postoperative AKI was significantly reduced, serum creatinine concentrations and the difference were decreased at T 2 and T 3, serum urea concentrations and the difference were decreased at T 2, the serum C-reactive protein concentration and the difference were decreased at T 1 and T 3, and the procalcitonin concentration and the difference were decreased at T 3 ( P<0.05), and no statistically significant differences were found in the serum lactate and interleukin-6 concentrations and the difference at each time point, in-hospital case fatality rate, duration of postoperative mechanical ventilation, or length of intensive care unit stay in group L ( P>0.05). Conclusions:Intraoperative intravenous lidocaine infusion can reduce the occurrence of postoperative AKI and improve renal function in patients with enterogenic sepsis.

This study investigates the expression pattern and functional significance of EF-hand domain-containing protein 2 (EFHD2) in hepatocellular carcinoma (HCC), with particular focus on its regulatory effects on tumor proliferation, migration, and invasion. Cellular experimental study was completed from June 2024 to January 2025 in the Basic Laboratory of the General Hospital of Southern Theater Command. TCGA database to determine EFHD2 expression and its clinicopathological correlations. GSCA database to assess methylation patterns and immune infiltration. Model of transient overexpression and knockdown of EFHD2 was constructed in hepatocellular carcinoma cells Hep3B, then RT-qPCR and Western blot were applied to verify the transfection efficiency. CCK-8 and colony formation assays for proliferation assessment, Transwell chambers for migration/invasion quantification. Protein-protein interaction networks were constructed via STRING, followed by GO/KEGG enrichment analysis. Statistical analysis was performed using the two independent samples t-test. The results showed that EFHD2 demonstrated significant upregulation in HCC tissues versus normal controls ( P<0.05). Elevated EFHD2 expression correlated with advanced clinical stage ( P<0.05) and poor differentiation ( P<0.05). In the CCK-8 assay, the EFHD2 overexpression group demonstrated significantly higher cell viability than the control group, as evidenced by 450 nm relative absorbance values on Day 1 (0.529±0.019 vs. 0.515±0.016, F=0.041, P=0.320), Day 2 (1.356±0.019 vs. 1.094±0.042, F=3.833, P<0.001), Day 3 (2.817±0.049 vs. 2.143±0.124, F=3.833, P<0.001), and Day 4 (3.848±0.015 vs. 3.430±0.021, F=0.469, P<0.001). The EFHD2 knockdown group showed reduced cell viability compared to controls: Day 1 (0.541±0.020 vs. 0.552±0.015, F=0.098, P=0.423), Day 2 (1.154±0.009 vs. 1.326±0.029, F=2.485, P<0.001), Day 3 (2.453±0.041 vs. 2.653±0.031, F=0.479, P<0.001), and Day 4 (3.685±0.038 vs. 3.836±0.021, F=6.804, P<0.001). In colony formation assays, the overexpression group displayed a significant increase in colony numbers (254.667±23.861 vs. 186.000±16.703, F=0.865, P=0.015), whereas the knockdown group exhibited decreased colony formation (229.000±24.637 vs. 306.667±36.501, F=0.988, P=0.038). In Transwell assays, the EFHD2 overexpression group revealed enhanced migratory capacity [ (605.000±72.670) cells vs. (472.667±28.095) cells, F=2.462, P=0.042] and invasive potential [(767.333±21.221) cells vs. (414.333±16.623) cells, F=0.331, P<0.001]. The knockdown group showed attenuated migration [(311.000±71.084) cells vs. (479.667±50.846) cells, F=0.718, P=0.029] and invasion [(247.667±48.263) cells vs. (345.667±32.130) cells, F=0.727, P=0.043] compared to controls. The network of EFHD2-interacting proteins was further constructed by the STRING database, and the GO and KEGG analysis were used to perform bioinformatics analysis reveal that EFHD2 is mainly involved in actin cytoskeleton regulation. In conclusion, EFHD2 is highly expressed in HCC and is involved in the process of proliferation, migration and invasion of HCC.

BACKGROUND: Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS. METHODS: This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide. RESULTS: Eighty-two patients were assigned to variant ( n  = 42) and wild type groups ( n  = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study. CONCLUSION: ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

【Objective】 To investigate the expressions of containing CKLF like MARVEL transmembrane domain gene 6 (CMTM6) and ras protein activator like 2 (RASAL2) in prostate cancer tissues, and to analyze the relationships between the above factors and the clinicopathological characteristics and prognosis of prostate cancer patients. 【Methods】 The prostate cancer tissues and adjacent tissues of 80 prostate cancer patients admitted to Zhumadian City Center Hospital during Feb.2018 and Feb.2020 were collected.Expressions of CMTM6 and RASAL2 were detected with immunohistochemical method.The relationship between the expressions of CMTM6 and RASAL2 and the clinical pathological characteristics of prostate cancer were analyzed.The survival curve was plotted with Kaplan-Meier method.The prognostic factors were analyzed with multivariate Cox regression. 【Results】 The positive expression rate of CMTM6 in prostate cancer tissues was 67.50%, which was obviously higher than 38.75% in adjacent tissues (χ²=13.277, P<0.001).The positive expression rate of RASAL2 in prostate cancer tissues was 47.50%, which was obviously lower than 73.75% in adjacent tissues (χ²=11.546, P=0.001).The expressions of CMTM6 and RASAL2 were not related to patients’ age, tumor size and tissue differentiation (P>0.05), but to TNM staging, Gleason score, lymph node metastasis and preoperative PSA level (P<0.05).Survival curve showed that the 3-year survival rate of positive CMTM6 expression patients was 61.11% (33/54), which was obviously lower than that of negative patients, which was 88.46% (23/26) (χ²=5.940, P=0.015).The 3-year survival rate of positive RASAL2 expression patients was 81.85% (31/38), which was obviously higher than that of negative patients, which was 59.52% (25/42) (χ²=4.887, P=0.027).Cox multivariate regression showed that Gleason score, lymph node metastasis, preoperative PSA level, CMTM6, and RASAL2 were independent influencing factors of prognosis (P<0.05). 【Conclusion】 The positive expression rate of CMTM6 in prostate cancer tissues is significantly higher than that in paracancer tissues, while the positive expression rate of RASAL2 in prostate cancer tissues is significantly lower than that in paracancer tissues. Both CMTM6 and RASAL2 are closely related to the clinical pathological characteristics and prognosis of prostate cancer patients, and may provide reference for the prognosis.
