Objective:To investigate the clinical effects and advantages of laparoscopic total mesorectal excision in the treatment of colorectal cancer.Methods:A total of 82 patients with colorectal cancer who received treatment at the Second Affiliated Hospital of Guizhou Medical University from January 2020 to January 2023 were selected for a prospective study. They were randomly assigned to two groups using a random number table, with 41 cases in each group. The control group underwent conventional laparotomy, while the observation group received laparoscopic total mesorectal excision. Clinical efficacy, clinical indicators, and immune function indicators were compared between the two groups.Results:The operation time for patients in the observation group was (1.98 ± 0.31) hours, the length of hospital stay was (8.32 ± 2.38) days, the recovery time for bowel function was (2.15 ± 0.34) days, and the intraoperative blood loss was (112.35 ± 12.66) mL, all of which were shorter and lower than those in the control group [(2.46 ± 0.32) hours, (14.52 ± 2.42) days, (3.25 ± 0.15) days, and (167.78 ± 12.35) mL, t = 6.90, 11.70, 18.95, 20.07, all P < 0.001). The short-term response rate in the observation group was higher than that in the control group ( χ2 = 4.10, P < 0.05). The immune function indicators in the observation group, including the CD4 +/CD8 + ratio (1.78 ± 0.54), immunoglobulin A [(3.87 ± 0.73) g/L], and immunoglobulin G [(11.83 ± 2.88) g/L], were all better than those in the control group [(1.36 ± 0.53), (1.78 ± 0.63) g/L, (6.37 ± 2.45) g/L, t = 3.55, 13.88, 9.25, all P < 0.001]. The incidence of complications in the observation group was 2.44% (1/41), which was significantly lower than that in the control group [19.51% (8/41), χ2 = 4.49, P < 0.05]. Conclusions:Laparoscopic total mesorectal excision for patients with colorectal cancer has significant advantages, including faster recovery, less bleeding, and fewer complications, making it more superior to conventional laparotomy.

Objective:To analyze the value of diffusion tensor imaging (DTI) combined with magnetic resonance spectroscopy (MRS) in the clinical grading and prognosis assessment of brain glioma.Methods:A retrospective analysis was conducted on the clinical data of 72 patients with brain glioma admitted to Yan'an People's Hospital from January 2010 to December 2023. The cohort included 40 males and 32 females, with ages ranging from 25 to 76 years and an average age of (40.3 ± 6.8) years. All patients underwent routine magnetic resonance imaging plain scans, contrast-enhanced ultrasound examination, DTI, and MRS prior to surgery. Measurements were conducted for fractional anisotropy (FA), N-acetyl aspartate (NAA), choline compounds (Cho), and creatinine (Cr). Additionally, the ratios of NAA/Cho, Cho/Cr, and NAA/Cr were calculated. The imaging characteristics of brain glioma were analyzed, and the clinical utility of these indicators for grading and prognosis assessment of brain glioma was evaluated.Results:DTI results of the 72 included patients revealed disruption of the white matter fiber tracts surrounding the tumors. MRS of the 72 included patients showed either approximately normal values or indicated elevated Cho and Cr levels, along with decreased NAA levels. Diffuse mild to moderate enhancement was observed in 35 patients (48.61%), presenting with a patchy pattern that suggested a higher tumor grade. When comparing low-grade gliomas (LGG) and high-grade gliomas (HGG) to the corresponding healthy tissue, significant differences were observed in FA value in the peritumoral edema region [(0.20 ± 0.06) × 10 -3 mm2/s vs. (0.62 ± 0.08) × 10 -3 mm2/s for LGG, and (0.17 ± 0.05) × 10 -3 mm2/s vs. (0.62 ± 0.09) × 10 -3 mm2/s for HGG] , NAA/Cho ratio [(0.36 ± 0.11) vs. (1.41 ± 0.33) for LGG, and (0.19 ± 0.06) vs. (1.42 ± 0.35) for HGG], Cho/Cr ratio [(2.39 ± 0.51) vs. (1.12 ± 0.26) for LGG, and (3.81 ± 0.94) vs. (1.12 ± 0.28) for HGG], and NAA/Cr ratio [(0.75 ± 0.24) vs. (1.52 ± 0.31) for LGG, and (0.38 ± 0.12) vs. (1.52 ± 0.29) for HGG]. All observed differences were statistically significant ( tLGG = 26.56, 19.09, 14.03, 12.42; tHGG = 27.64, 21.90, 17.34, 22.97, all P < 0.05). There were statistically significant differences in FA [(0.20 ± 0.06) × 10 -3 mm2/s vs. (0.17 ± 0.05) × 10 -3 mm2/s], NAA/Cho [(0.36 ± 0.11) vs. (0.19 ± 0.06)], Cho/Cr [(2.39 ± 0.51) vs. (3.81 ± 0.94)], and NAA/Cr [(0.75 ± 0.24) vs. (0.38 ± 0.12)] between LGG and HGG ( t = 2.26, 7.85, 8.17, 7.95, all P < 0.05). Follow-up conducted 6 months to 3 years postoperatively revealed that the Cho/Cr ratio in the death group was significantly higher than that in the survival group [2.172 (1.662, 2.863) vs. 2.729 (2.431, 3.689), U = 2.17, P < 0.05]. However, there were no statistically significant differences in FA, NAA/Cho, and NAA/Cr values between survival and death groups ( P > 0.05). Conclusions:Combined DTI and MRS can reveal specific imaging characteristics of brain gliomas, providing valuable information for clinical grading of brain gliomas. Furthermore, the Cho/Cr ratio is associated with prognosis and may serve as a potential imaging biomarker for predicting the outcome of brain gliomas.

Objective:To analyze pain factors and changes in humoral immunity in patients with postherpetic neuralgia (PHN).Methods:A retrospective study was conducted involving 120 patients with herpes zoster (HZ) admitted to Xi'an Daxing Hospital from February 2022 to February 2024. Among these patients, 60 who developed PHN symptoms within 3 months after recovering from HZ were designated as the complication group, while 60 who did not develop PHN symptoms after recovering from HZ were designated as the simple group. Additionally, 60 healthy volunteers who underwent physical examinations during the same period were included as the healthy group. Both the combination and simple groups received treatment for 1 month. Pain mediators [β-endorphin (β-EP), substance P (SP), serotonin (5-HT), calcitonin gene-related peptide (CGRP), and neurosecretory protein VGF], inflammatory factors [tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interferon-gamma (IFN-γ)], immunoglobulins (IgA, IgG, IgM), and T cell subsets (CD 3+, CD 4+, CD 8+, and CD 4+/CD 8+) were collected and compared among the three groups. Results:There were significant differences in the levels of β-EP, SP, 5-HT, CGRP, and VGF among the three groups ( F = 377.44, 988.37, 699.86, 800.74, 1421.88, all P < 0.05). The serum levels of TNF-α [(199.62 ± 21.13) μg/L and (194.61 ± 20.73) μg/L], IL-6 [(77.08 ± 12.91) μg/L and (58.70 ± 12.38) μg/L], and IFN-γ [(54.27 ± 6.21) mg/L and (29.17 ± 4.55) mg/L] in the complication and simple groups were significantly higher than those in the healthy group [(92.13 ± 11.54) μg/L, (46.13 ± 10.23) μg/L, and (12.58 ± 1.75) μg/L, all P < 0.05]. Additionally, the levels of IgA, IgG, IgM, and complement proteins (C3, C4) also showed statistically significant differences among the three groups ( F = 454.20, 237.78, 182.90, 33.11, 275.26, all P < 0.05). There was no statistically significant difference in cellular immunity levels between the simple and complication groups ( P > 0.05). However, the levels of T cell subsets (CD 3+, CD 4+, CD 8+) in both the simple and complication groups were lower than those in the healthy group, while the CD 4+/CD 8+ ratios were significantly higher in both the simple and complication groups compared to the healthy group (all P < 0.05). Pearson correlation analysis revealed that the serum level of β-EP was significantly negatively correlated with the serum levels of TNF-α, IL-6, IFN-γ, IgA, IgG, IgM, C3, and C4 (all P < 0.05). In contrast, the serum levels of SP, 5-HT, CGRP, and VGF were significantly positively correlated with the serum levels of TNF-α, IL-6, IFN-γ, IgA, IgG, IgM, C3, and C4 (all P < 0.05). Conclusions:The pain factors β-EP, SP, 5-HT, CGRP, and VGF, as well as the inflammatory cytokines TNF-α, IL-6, and IFN-γ, play important roles in the occurrence and persistence of neuropathic pain in patients with postherpetic neuralgia. The levels of immunoglobulins and T cell subsets in these patients serve as important indicators for analyzing changes in humoral immunity.

Objective:To investigate the effects of low-dose morphine epidural injection on postpartum analgesia.Methods:In this prospective study, 200 women who underwent painless delivery at Dongyang Maternal and Child Health Hospital from January to December 2023 were selected as research subjects. They were randomly divided into a control group ( n = 100) and an observation group ( n = 100) using a random number table method. The control group received an epidural injection of 0.9% sodium chloride solution postpartum, while the observation group received an epidural injection of 2 mg morphine postpartum. Analgesic effects, the degree of uterine contractions, breastfeeding status, and the incidence of adverse reactions were compared between the two groups. Results:The onset time of analgesia in the observation group was significantly shorter than that in the control group [(2.24 ± 0.64) minutes vs. (2.65 ± 0.71) minutes, t = 4.28, P < 0.05]. The duration of analgesia and pain recovery time were (327.19 ± 74.27) minutes and (56.29 ± 17.31) minutes, respectively, which were longer than those in the control group [(302.18 ± 62.31) minutes, (48.22 ± 12.06) minutes, t = -2.58, -3.82, both P < 0.05]. Within 24 hours postpartum, the intensity of uterine contraction pain gradually increased in both groups; however, the observation group consistently reported lower pain levels than the control group ( t = 16.14, 13.13, 12.85, 12.37, 11.15, all P < 0.05). The number of breastfeeding sessions in the observation group was significantly higher than that in the control group [(15.32 ± 3.52) vs. (10.85 ± 2.34), t = -10.57, P < 0.05]. On postpartum day 1, the prolactin levels in both groups were higher than pre-delivery levels, with the observation group showing higher levels [(338.65 ± 75.07) μg/L] compared with the control group [(271.37 ± 52.71) μg/L, t = -7.33, P < 0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group [10.00% (10/100) vs. 6.00% (6/100), χ2 = 1.08, P > 0.05). Conclusions:The use of low-dose morphine administered via epidural injection provides effective analgesia for postpartum uterine contraction pain, improves breastfeeding, and does not increase the incidence of adverse reactions.

Objective:To analyze the clinical distribution and antibiotic resistance of multidrug-resistant organism (MDRO) infections in the non-intensive care unit (ICU) of Jiangsu Provincial (Suqian) Hospital (Suqian First Hospital), providing a basis for effective implementation of infection prevention and control measures.Methods:Using the real-time monitoring system for hospital infections, this study selected 520 strains of MDROs isolated from non-ICU hospitalized patients at Jiangsu Provincial (Suqian) Hospital (Suqian First Hospital) from January 2020 to December 2023 for analysis. Based on their origin, these strains were categorized into two groups: hospital-acquired infections and community-acquired infections. The clinical distribution characteristics of MDRO infections and their resistance rates to commonly used antimicrobial agents were analyzed.Results:The average detection rate of MDRO in non-ICU over 4 consecutive years was 13.60% (782/5 750). The detection rates for methicillin-resistant Staphylococcus aureus (MRSA), carbapenem-resistant Acinetobacter baumannii (CRAB), carbapenem-resistant Pseudomonas aeruginosa (CRPA), and carbapenem-resistant Enterobacteriaceae were 46.49% (424/912), 43.81% (85/194), 18.61% (177/951), and 2.60% (96/3 693), respectively. The predominant MDROs identified were MRSA (54.23%, 282/520) and CRPA (28.65%, 149/520). Hospital-acquired infections accounted for 13.65% (71/520), while community-acquired infections comprised 86.35% (449/520). The three departments with the highest infection rates were the Department of Respiratory (22.31%), the Department of Pediatrics (15.19%), and the Department of Traditional Chinese Medicine and Burn (7.88%). All of these departments were primarily associated with community-acquired infections. Statistically significant differences were observed in the composition of MDRO infections among different departments ( P < 0.05). The largest proportion of specimens was obtained from sputum (59.81%), followed by wound secretions (20.77%). Sputum samples exhibited a higher proportion in community-acquired infections compared to hospital-acquired infections (63.25% vs. 38.03%, χ2 = 16.23, P < 0.05). The lower respiratory tract was identified as the primary site for community-acquired infections. Antimicrobial susceptibility testing revealed that CRAB was 100% resistant to penicillins, carbapenems, and most cephalosporins. CRPA demonstrated 100% resistance to penicillins and trimethoprim-sulfamethoxazole, but showed lower resistance rates for other antibiotics compared to CRAB and carbapenem-resistant Klebsiella pneumoniae. MRSA was 100% resistant to penicillin and cefoxitin, but exhibited a resistance rate of 0% to tigecycline and linezolid. Conclusions:In our hospital, 86.35% of MDRO infections in non-ICU departments originated from the community, primarily involving MRSA and CRPA. There were significant differences in the proportion of MDRO infections across different departments, and resistance to carbapenem antibiotics was serious. Infection prevention and control departments should implement targeted prevention strategies based on these distribution characteristics.

Objective:To investigate the effects of a single intravenous injection of low-dose esketamine during cesarean section on postpartum depression in primiparas.Methods:This study is a prospective randomized controlled trial involving 106 primiparas who underwent scheduled intrathecal anesthesia for cesarean section at Xi'an International Medical Center Hospital from January 2021 to December 2023. The participants were randomly assigned to either the control group or the observation group, with 53 women in each group, using a random number table method. Both groups received the same type and method of anesthesia. In the observation group, 5 minutes after the delivery of the fetus and the clamping of the umbilical cord, a low dose of esketamine (0.2 mg/kg, dissolved in 10 mL of 0.9% sodium chloride injection) was administered intravenously. The control group received an equivalent volume of 0.9% sodium chloride injection as a placebo. The score of the Edinburgh Postnatal Depression Scale at various postpartum time intervals (3, 7, 14, 30, and 42 days), the incidence of postpartum depression, and any adverse drug reactions occurring within 3 days postoperatively were compared between the two groups. Additionally, the score of the Visual Analog Scale (VAS) for contraction pain was assessed.Results:The scores of the Edinburgh Postnatal Depression Scale in the observation group at 3, 7, 14, 30, and 42 days postpartum were (6.23 ± 1.21), (5.82 ± 1.77), (6.14 ± 1.20), (5.33 ± 1.19), and (6.01 ± 1.23), respectively. These scores were significantly lower than those in the control group [(8.99 ± 1.28), (8.91 ± 2.11), (9.03 ± 1.94), (10.40 ± 2.68), (9.28 ± 1.84), t = 11.40, 8.16, 9.22, 12.58, 10.75, all P < 0.001]. The incidence of postpartum depression in the observation group at 7 and 14 days postpartum was significantly lower than that in the control group [3.77% (2/53) vs. 16.98% (9/53), 3.77% (2/53) vs. 15.09% (8/53), χ2 = 4.97, 3.97, P = 0.026, 0.046]. There was no statistically significant difference in the incidence of adverse drug reactions within 3 days postoperatively between the two groups of women who underwent scheduled intrathecal anesthesia for cesarean section [15.09% (8/53) vs. 11.32% (6/53), χ2 = 0.32, P = 0.566]. The scores of the Visual Analog Scale for contraction pain in the observation group at 3, 6, 12, and 24 hours postoperatively were (2.13 ± 0.28), (2.55 ± 0.33), (2.73 ± 0.35), and (3.06 ± 0.37), respectively. These scores were significantly lower than those in the control group [(4.35 ± 0.46), (5.43 ± 0.36), (5.68 ± 0.35), (5.26 ± 0.43), t = 30.01, 42.93, 43.38, 28.23, all P < 0.001]. Conclusions:A single intravenous injection of low-dose esketamine during cesarean section can effectively alleviate emotional distress in primiparas in the short term after surgery, which has significant clinical implications for reducing the incidence of postpartum depression.

Objective:To investigate the clinical efficacy of stamp skin grafting combined with vacuum sealing drainage in the treatment of diabetic foot ulcers.Methods:A prospective study was conducted involving 80 patients with diabetic foot ulcers admitted to Lishui Central Hospital from January 2020 to December 2022. The patients were divided into an observation group and a control group, with 40 patients in each group, using a random number table method. The control group received treatment with vacuum-sealing drainage technology, while the observation group was treated with stamp skin grafting combined with vacuum sealing drainage. The two groups were compared based on several perioperative indicators, including wound healing time, length of hospital stay, number of dressing changes, and progress of granulation tissue growth. Pain levels were assessed using the Visual Analog Scale. Additionally, dorsalis pedis blood flow dynamics were evaluated, focusing on the diameter of the dorsalis pedis artery and arterial blood flow velocity. Foot function was assessed using the Maryland Foot Function Scale. The occurrence of postoperative complications was recorded.Results:The wound healing time and length of hospital stay in the observation group were (21.54 ± 5.32) days and (27.08 ± 5.97) days, respectively, which were significantly shorter than those in the control group [(26.69 ± 5.66) days, (31.49 ± 6.80) days, t = 4.19, 3.08, both P < 0.05]. The number of dressing changes in the observation group was (5.11 ± 1.14), which was significantly fewer than that in the control group [(8.07 ± 1.59), t = 9.56, P < 0.001]. The progress of granulation tissue growth in the observation group [(3.12 ± 0.64) mm] was faster that in the control group [(2.09 ± 0.48) mm, t = 8.14, P < 0.001]. At 1, 2, and 3 months post-surgery, the Visual Analog Scale scores for the observation group were (3.52 ± 0.65), (2.33 ± 0.42), and (1.40 ± 0.26), respectively, which were significantly lower than those in the control group [(3.96 ± 0.71), (2.74 ± 0.44), (1.78 ± 0.34), t = 2.89, 4.26, 5.615, all P < 0.05). At 3 months post-surgery, the diameter of the dorsalis pedis artery and arterial blood flow velocity in the observation group were (2.64 ± 0.44) mm and (36.42 ± 6.28) cm/s, respectively, which were greater than those in control group [(2.18 ± 0.41) mm, (30.97 ± 5.33) cm/s, t = 4.83, 4.18, both P < 0.001]. At 3 months post-surgery, the scores for pain, foot function, appearance, and range of motion in the observation group were (39.28 ± 6.70), (48.10 ± 7.22), (7.94 ± 1.54), and (12.15 ± 2.35), respectively, which were significantly higher than those in the control group [(33.46 ± 6.89), (43.08 ± 6.68), (5.38 ± 1.06), and (10.69 ± 2.16), t = 3.83, 3.22, 8.66, 2.89, all P < 0.05]. There was no statistically significant difference in the overall incidence of postoperative complications, including skin flap necrosis/dislocation, hematoma accumulation, infection, and ulcer recurrence, between the two groups ( P > 0.05). Conclusions:Stamp skin grafting combined with vacuum sealing drainage can significantly accelerate wound healing in patients with diabetic foot ulcers, reduce postoperative pain, improve dorsalis pedis blood flow dynamics, enhance foot function, and demonstrate good safety.

Objective:To analyze the neuropsychological characteristics of patients with chronic heart failure (CHF) complicated by mild cognitive impairment (MCI) and investigate the factors that influence the development of CHF complicated by MCI.Methods:A case-control study was conducted to retrospectively analyze the clinical data of 98 patients with CHF admitted to Baoji Hospital of Traditional Chinese Medicine from January 2019 to October 2020. Based on the Petersen MCI screening criteria, the patients were divided into the MCI group ( n = 48) and the normal cognitive group (NC group, n = 50). The neuropsychological characteristics were analyzed using the Mini-Mental State Examination and the Montreal Cognitive Assessment. The cognitive domain scores of the two groups were tested and compared. Logistic regression analysis was performed to identify the factors influencing the development of CHF complicated by MCI. Results:The total scores of the Mini-Mental State Examination and the Montreal Cognitive Assessment in the NC group were 28.45 ± 1.10 and 27.90 ± 1.35, respectively, which were significantly higher than those in the MCI group (23.50 ± 2.25, 22.95 ± 1.35, t = 13.92, 18.15, both P < 0.001). In addition, the NC group outperformed the MCI group in terms of the number of correct readings, time taken, attention, visuospatial function, memory, and language function ( t = 2.94, 7.29, 3.15, 9.90, 14.69, 4.87, all P < 0.01). The MCI group had a greater proportion of patients who were aged ≥ 65 years, had an education level of junior high school or below, experienced sleep disorders, and were classified as New York Heart Association (NYHA) functional class Ⅲ, compared with the NC group ( χ2 = 4.18, 4.08, 6.88, 4.70, all P < 0.05). Additionally, the cardiac output was lower in the MCI group than in the NC group ( t = 4.70, P < 0.05). Logistic regression analysis revealed that age ≥ 65 years ( OR = 3.904, 95% CI: 1.530-9.963), education level of junior high school or below ( OR = 2.565, 95% CI: 1.571-4.187), sleep disorders ( OR = 3.080, 95% CI: 1.445-6.564), and low cardiac output ( OR = 1.784, 95% CI: 1.168-2.725) were independent risk factors for CHF complicated by MCI ( P < 0.05). Conclusions:Patients with CHF complicated by MCI are more likely to experience impairments in visuospatial function, executive function, attention, language function, and memory. Independent risk factors for CHF complicated by MCI include age ≥ 65 years, education level of junior high school or below, sleep disorders, and low cardiac output.

Objective:To investigate the diagnostic value of umbilical cord blood lactic acid and base excess for multi-organ dysfunction following neonatal asphyxia.Methods:A retrospective analysis was conducted on the clinical data of 244 patients at high risk for perinatal asphyxia who received treatment at Dongyang People's Hospital from January 2021 to December 2023.Based on the presence of organ dysfunction, the infants were divided into three groups: a single organ dysfunction group (Group A, n = 55), a multi-organ dysfunction group (Group B, n = 16), and a no organ dysfunction group (Group C, n = 173). Lactic acid levels and base excess values were compared among the three groups. Receiver operating characteristic curves were used to validate the predictive value of lactic acid and base excess values for organ dysfunction. Results:There were no statistically significant differences in general data among the three groups ( P > 0.05). In Group B, the lactic acid level was 15.10 (13.85, 16.83) mmol/L, and the base excess value was 9.80 (6.65, 15.18) mmol/L. In Group A, the lactic acid level was 7.70 (6.25, 11.70) mmol/L, and the base excess value was 5.70 (3.85, 9.60) mmol/L. In Group C, the lactic acid level was 6.80 (4.30, 9.00) mmol/L, and the base excess value was 4.00 (3.00, 6.50) mmol/L. The lactic acid level and base excess value in Group B were significantly higher than those in both Group A and Group C. Additionally, the lactic acid level and base excess value in Group A were significantly greater than those in Group C ( t = 2.60, 20.19, 2.95, 1.92, all P < 0.05). Receiver operating characteristic curve analysis revealed that the combined assessment of base excess value and lactic acid level was more effective than evaluating each parameter individually in predicting the presence of organ damage and multiple organ dysfunction syndrome. Additionally, the detection of base excess value was found to be superior to the measurement of lactic acid level. The areas under the curve values for the combined assessment of base excess value and lactic acid level for the presence of organ damage and multiple organ dysfunction syndrome were 0.694 and 0.856, respectively. In comparison, the AUC values for base excess value detection were 0.678 and 0.846, while the AUC values for lactic acid level measurement were 0.633 and 0.797, respectively. Conclusions:Umbilical cord blood lactic acid and base excess are correlated with organ dysfunction following neonatal asphyxia, and both parameters have clinical value in assessing organ damage.

Objective:To investigate the effects of hepatic fatty acid transporter 5 (FATP5) gene expression on the levels of free long-chain fatty acid (LCFA) in mice with metabolic associated fatty liver disease (MAFLD).Methods:From June to December 2022, a prospective study was conducted with three experimental groups: wild-type (WT) group, FATP5 gene expression negative (FATP5 -) group, and human FATP5 gene expression positive (hFATP5 +) group, with 10 mice in each group. Each group of mice was fed a high-fat diet for 16 weeks to establish a model of MAFLD. Hepatic tissue changes were observed using hematoxylin-eosin staining. The liver mass and liver coefficient of the mice were measured. Total cholesterol (TC), triglycerides (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), uric acid (UA), and LCFA levels were determined using an automatic biochemical analyzer. Blood glucose (Glu) levels were measured using a blood glucose analyzer. The liver mass and liver coefficient, TC and TG levels, AST and ALT levels, Glu and UA levels, and LCFA levels were compared among the three groups. Results:In the WT group, there was significant inflammatory cell infiltration within the hepatocytes and a large amount of fat accumulation. In the FATP5 - group, the inflammatory cell infiltration in the hepatocytes was mild with slight fat accumulation. In the hFATP5 + group, the inflammatory cell infiltration in the hepatocytes was severe, with great fat accumulation. The liver mass [(1.27 ± 0.25) g], liver coefficient (2.38 ± 0.19), TC [(1.82 ± 0.26) mmol/L], TG [(0.93 ± 0.24) mmol/L], AST [(169.95 ± 37.73) U/L], ALT [(95.36 ± 21.49) U/L], Glu [(8.34 ± 1.52) mmol/L], and UA [(74.32 ± 15.52) μmol/L] in the FATP5 - group were all significantly lower than those in the WT group [(1.61 ± 0.23) g, (2.71 ± 0.20), (2.31 ± 0.28) mmol/L, (1.34 ± 0.21) mmol/L, (278.31 ± 43.24) U/L, (147.32 ± 28.81) U/L, (10.52 ± 1.24) mmol/L, (96.28 ± 17.43) μmol/L], while the LCFA level [(3.57 ± 0.48) mg/L] in the FATP5 - group was significantly higher than that in the WT group [(2.63 ± 0.56) mg/L] ( t = 3.17, 3.78, 4.06, 4.07, 5.97, 4.57, 3.51, 2.98, 4.03, all P < 0.05). In the hFATP5 + group, the liver mass [(1.92 ± 0.30) g], liver coefficient (2.95 ± 0.23), TC [(2.59 ± 0.24) mmol/L], TG [(1.76 ± 0.35) mmol/L], AST [(341.22 ± 48.98) U/L], ALT [(189.45 ± 17.97) U/L], Glu [(13.21 ± 1.98) mmol/L], and UA [(117.74 ± 18.38) μmol/L] were all significantly higher than those in the WT group, while the LCFA level [(3.57 ± 0.48) mg/L] in the FATP5 + group was significantly lower than that in the WT group ( t = 2.59, 2.49, 2.40, 3.25, 3.04, 3.92, 3.64, 2.68, 3.19, all P < 0.05). Conclusions:The absence of FATP5 in the liver can elevate blood levels of LCFA in mice with MAFLD, reduce food intake, and help alleviate the symptoms of MAFLD.
