ABSTRACT
Immune-related adverse events (irAEs) clinically resemble autoimmune diseases, indicating autoantibodies could be potential biomarkers for the prediction of irAEs. This study aimed to assess the predictive value of peripheral blood antinuclear antibody (ANA) status for irAEs, considering the time and severity of irAEs, as well as treatment outcome in liver cancer patients administered anti-PD-1 therapy. Ninety-three patients with advanced primary liver cancer administered anti-PD-1 treatment were analyzed retrospectively. They were divided into the ANA positive (ANA+, titer ≥ 1:100) and negative (ANA-, titer < 1:100) groups. Development of irAEs, progression-free survival (PFS), and overall survival (OS) were assessed. Compared with ANA- patients, ANA+ cases were more prone to develop irAEs (43.3% vs. 19.2%, P = 0.031). With the increase of ANA titers, the frequency of irAEs increased. The time interval between anti-PD-1 therapy and the onset of irAEs was significantly shorter in ANA+ patients compared with the ANA- group (median, 1.7 months vs. 5.0 months, P = 0.022). Moreover, the time between anti-PD-1 therapy and irAE occurrence decreased with increasing ANA titer. In addition, PFS and OS were decreased in ANA+ patients compared with the ANA- group (median PFS, 2.8 months vs. 4.2 months, P = 0.043; median OS, 21.1 months vs. not reached, P = 0.041). IrAEs occur at higher frequency in ANA+ liver cancer patients undergoing anti-PD-1 therapy. ANA titer could help predict irAE development and treatment outcome in these patients.

AIMS: The aim of this study was to develop, implement and evaluate a nurse-led shared decision-making model of care for discussing the use of complementary and alternative medicine with diabetic patients and to explore to what extent the risk-benefit assessment of using complementary and alternative medicine can provide a framework for facilitating nurse-patient dialogue and strengthening patient involvement in their disease management. DESIGN: Participatory action research with pre-post intervention. METHODS: A two-run cycle of action and spirals from participatory action research was undertaken using a purposive sampling method to involve healthcare professionals and diabetic patients from September 2021 to June 2022. The nurse-led shared decision-making model of care was designed and implemented congruent with participatory action research principles. Quantitative measures were collected about patients' perceived involvement in shared decision-making and their understanding of the risks and benefits of using complementary and alternative medicine. Patients' outcomes of disease control (fasting plasma glucose and HbA1c) were also collected. Data were analysed using IBM SPSS software (version 28). Interviews were summarized using thematic analysis. An EQUATOR Network guideline for participatory action research supported the preparation of this paper. RESULTS: Comparison of pre-post intervention outcomes showed that patients' scale scores on shared decision-making involvement and understanding of the risk-benefit of using complementary and alternative medicine improved significantly after implementing the model. Fasting plasma glucose improved only slightly after a 3-month follow-up. CONCLUSIONS: The care model strengthens patient involvement in their disease management and makes appropriate decisions about CAM use that should reduce potentially harmful side effects or interactions between CAM and conventional medicine. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: The shared decision-making model of care incorporates evidence-based CAM research into practice, facilitates the standardization of CAM management in diabetes, improves care options for patients and educates nurses about CAM use in managing diabetes. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

The aim of this study was to evaluate the application potential of a recombinant fungal immunomodulatory protein from Ganoderma lucidum (rFIP-glu). First, a recombinant plasmid pPIC9K::FIP-glu-His was transferred into Pichia pastoris for the production of protein. The protein was then to assess its free radical scavenging abilities and the effect on the viability of both human immortalized keratinocytes (HaCaT cells) and mouse B16-F10 melanoma cells (B16 cells) in vitro, followed by the effect on the melanin synthesis of B16 cells. The results of SDS-PAGE and western blot showed that rFIP-glu was successfully expressed. Furtherly, a bioactivity assay in vitro indicated that the scavenging rate of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals reached 84.5% at 6.0 mg/mL (p ≤ 0.0001) of rFIP-glu, showing strong antioxidant activity. Subsequently, a safety evaluation demonstrated that rFIP-glu promoted the proliferation of HaCaT cells, with the cell viability reaching 124.3% at 48 µg/mL (p ≤ 0.01), regarding the cell viability of B16 cells after exposure to rFIP-glu (48 µg/mL) significantly inhibited, to 80.7% (p ≤ 0.01). Besides, rFIP-glu inhibited the melanin synthesis of B16 cells in a dose-dependent manner from 100-1000 µg/mL, and rFIP-glu at 500 µg/mL (p ≤ 0.01) exhibited the highest intracellular melanin amount reduction of 16.8%. Furthermore, a mechanism analysis showed that rFIP-glu inhibited tyrosinase (TYR) activity by up-regulating the expression of the microphthalmia-associated transcription factor (MITF) and down-regulating the gene expression of TYR and tyrosinase-related protein-1 (TYRP-1), thus inhibiting melanin synthesis. The data implied that rFIP-glu had significant antioxidant activity and whitening potency. It should be used as raw materials for cosmeceutical applications.

Pulmonary arterial hypertension (PAH) is a common and fatal complication of systemic lupus erythematosus (SLE). Whether the BMP receptor deficiency found in the genetic form of PAH is also involved in SLE-PAH patients remains to be identified. In this study, we employed patient-derived samples from SLE-associated PAH (SLE-PAH) and established comparable mouse models to clarify the role of BMP signaling in the pathobiology of SLE-PAH. Firstly, serum levels of LPS and autoantibodies (auto-Abs) directed at BMP receptors were significantly increased in patients with SLE-PAH compared with control subjects, measured by ELISA. Mass cytometry was applied to compare peripheral blood leukocyte phenotype in patients prior to and after treatment with steroids, which demonstrated inflammatory cells alteration in SLE-PAH. Furthermore, BMPR2 signaling and pyroptotic factors were examined in human pulmonary arterial endothelial cells (PAECs) in response to LPS stimulation. Interleukin-8 (IL-8) and E-selectin (SELE) expressions were up-regulated in autologous BMPR2+/R899X endothelial cells and siBMPR2-interfered PAECs. A SLE-PH model was established in mice induced with pristane and hypoxia. Moreover, the combination of endothelial specific BMPR2 knockout in SLE mice exacerbated pulmonary hypertension. Pyroptotic factors including gasdermin D (GSDMD) were elevated in the lungs of SLE-PH mice, and the pyroptotic effects of serum samples isolated from SLE-PAH patients on PAECs were analyzed. BMPR2 signaling upregulator (BUR1) showed anti-pyroptotic effects in SLE-PH mice and PAECs. Our results implied that deficiencies of BMPR2 signaling and proinflammatory factors together contribute to the development of PAH in SLE.

The current study aimed to investigate the effects of group reminiscence therapy on cognitive function, depression, neuropsychiatric symptoms, and activities of daily living in patients with mild-to-moderate Alzheimer disease (AD). A single-blind randomized parallel-design controlled trial was conducted between May 1, 2017, and April 30, 2018. Ninety patients with mild-to-moderate AD recruited from Beijing Geriatric Hospital were randomly allocated into intervention (n = 45) and control groups (n = 45). In the intervention group, group-based reminiscence therapy was performed in two 30- to 45-minute sessions weekly for 12 weeks. Control participants received only conventional drug treatments and routine daily care. Alzheimer disease-related symptoms were evaluated using the Alzheimer's Disease Assessment Scale-Cognitive section, the Cornell Scale for Depression in Dementia (CSDD), the Neuropsychiatric Inventory, and the Barthel Index. Four time points were set for data collection: baseline (before treatment), 4 weeks (during treatment), 12 weeks (end of treatment), and 24 weeks (12 weeks posttreatment). χ2 Tests, independent t tests, repeated-measures analysis of variance, and Bonferroni tests were used for data analysis. Significant improvements in depressive and neuropsychiatric symptoms were found in the intervention group compared to the control group (P < .05). Mean CSDD scores in the intervention group were improved at all 3 time points compared to baseline and showed the greatest effect at 12 weeks (t = 2.076, P = .041) and 24 weeks follow-up (t = 3.834, P = .000) compared to controls. Group reminiscence therapy was effective for improving depressive symptoms and was beneficial for treating neuropsychiatric symptoms in patients with AD.

In order to obtain a better fermentation parameter for the production of recombinant Ganoderma lucidum immunomodulatory protein (rFIP-glu), an engineered Pichia pastoris GS115 was investigated on the fermentation time, temperature, methanol concentration and initial pH of media, while immunomodulatory activities of the rFIP-glu was confirmed. L9(33) orthogonal experiment were firstly employed to optimize various fermentation parameters in the shake-flask level. The optimized fermentation parameters were subsequently verified in a 5 L fermenter. Biological activities including cell viability and tumor necrosis factor-alpha (TNF-α) mRNA of the rFIP-glu were evaluated on murine macrophage RAW264.7 cells. The results showed that the yield of rFIP-glu was up to 368.71 µg/ml in the shake-flask, and 613.47 µg/ml in the 5 L fermenter, when the Pichia pastoris was incubated in basic media with the methanol concentration 1.0% and initial pH 6.5, and with constant shaking at 280 rpm for 4 days at 26 °C. In vitro assays of biological activity indicated that rFIP-glu had significant toxicity against RAW264.7 cells, and possessed the ability to induce TNF-α mRNA expression in macrophage RAW264.7 cells. In conclusion, engineered P. pastoris showed a good fermentation property under the optimum fermentation parameters. It could be a candidate industrial strain for further study.

Ganoderma have been regarded as a traditional source of natural bioactive compounds for centuries and have recently been exploited for potential components in the cosmetics industry. Besides Ganoderma polysaccharides and triterpenes, multiple proteins have been found in Ganoderma. With the in-depth study of these proteins, various pharmacological functions of Ganoderma have become important in the discovery and development of new products. In the review, we summarized and discussed the kinds and characteristics of Ganoderma proteins, especially on fungal immunomodulatory proteins (FIPs) which can be potentially developed into cosmeceuticals or nutricosmetics and are a suitable target for production using established biotechnological methods. Furthermore, we discuss their pharmacological activities of the proteins with a focus on their pharmacological functions related to cosmetics, such as antioxidant activity, inhibition of melanin, antibacterial activity, and regulation of inflammatory mediators. Numerous other questions also are addressed before the proteins can be widely accepted and used as cosmetic additives.

The aim of this paper was to investigate the flavonoids of callus of transgenic and non-transgenic Saussurea involucrate and its antitumor activity on the esophageal cancer CaEs-17 cells. The species and content of mono-phenols were detected by high performance liquid chromatography. The growth of human esophageal cancer CaEs-17 cells was detected using CCK-8 assay, apoptosis morphology observation and flow cytometry. Expression of related apoptotic genes Bax and Bcl-2 were determined by qPCR. The results showed that the content of total flavonoids in the transgenic callus was 2.72 times that of the non-transgenic callus. The cyanidin-galactoside was detected in the transgenic callus, but not in the non-transgenic callus. The inhibitory effect of the extracts from the transgenic callus on CaEs-17 cells was more significant than that of the non-transgenic callus, and the IC50 value had a decreased of 26.4%. Flow cytometry analysis results showed that the apoptosis induction effect of the extracts from the transgenic callus on CaEs-17 cells was significantly better than that of the non-transgenic callus. Fluorescence quantitative PCR analysis results showed that the extracts from the transgenic callus could up-regulate the expression of proapoptotic gene Bax and down-regulate the expression of apoptotic gene Bcl-2, and the regulation effect of the transgenic callus was more significant. Therefore, compared with the non-transgenic callus, the antitumor activity of the extracts from the callus of transgenic S. involucrate on the esophageal cancer CaEs-17 cells was significantly increased, which was closely related to the accumulation of cyanidin-galactoside and its metabolism-related flavonoid compounds in the transgenic callus.

Iris lactea is a perennial halophyte and is tolerant to Cd. However, the mechanisms underlying this Cd tolerance are still poorly understood. In this study, morphological, physiological and biochemical responses of I. lactea to a 21 d exposure to different concentrations of Cd (0-150mgL-1) were investigated. I. lactea plants showed no toxicity symptoms except for a small reduction in growth at 100 and 150mgL-1 Cd, along with the enhancement of H2O2 and MDA content in comparison to the control. The activities of SOD and POD were significantly enhanced and Ca accumulated with increasing Cd concentrations. Moreover, most Cd was retained in roots and only a small amount was transported to the shoots with increasing external Cd concentrations. Cd content had a negative correlation with content of K, Fe, Zn, and Mn and a positive correlation with Mg content in shoots and roots, which had no influence on these contents of mineral nutrients in shoots and chlorophyll levels with the increase of Cd concentrations. The Cd translocation factors were always less than 1 and bioaccumulation factors ranged from 3.43 to 15.6 across all treatments, suggesting that I. lactea might be effectively used in phytostabilization of Cd contaminated soils. Overall, the findings suggest that I. lactea could reduce photoinhibition and oxidative damage and maintain metal ion homeostasis in plant tissue by limiting translocation of Cd from roots to shoots and enhancing induction of antioxidant enzyme activities, thereby improving its Cd tolerance.

OBJECTIVE: To investigate the prevalence and risk factors for chronic kidney disease (CKD) among community elderly population in Shanghai, China, in order to provide early diagnosis and treatment of CKD, and improve the quality of life for elderly people. METHODS: In all, 24,886 residents (≥65 years old) were selected from community population in Changning District of Shanghai, China in 2014. They were interviewed and tested for reduced renal function estimated GFR by CKD-EPI equation. The associations among demographic characteristics, healthy characteristics (e.g., cardiovascular disease and hypertension), and indicators of kidney damage were examined. RESULTS: Approximately, 16.4% of the participants were CKD. The average of them was 74.9 ± 7.0 years old. Females had a significantly higher prevalence of CKD than males (17.6% vs. 14.9%). CKD patients were present in higher prevalence of female, hyperuricemia (29.6% vs. 18.7%), hypertension (45.1% vs. 40.3%), and cardiovascular disease (23.2% vs. 18.7%) than that of non-CKD population. CKD patients were present in lower prevalence of drinking than that of non-CKD population. The prevalence of CKD in female is 2.002 times than that of male. The prevalence of CKD increased 1.048 times with the age of each increase in 1 year old. The risk factors for CKD are age, female, hyperuricemia, cardiovascular disease, hypertension, hypercholesterolemia, and smoking. CONCLUSIONS: The prevalence of CKD is high in the elderly population than that of adult CKD in Shanghai. The most risk factors for elderly CKD patients are similar to the adult population. But hypercholesterolemia as a risk fact of elderly CKD is different from adult CKD.

Hepatic fibrosis is a naturally occurring wound-healing reaction, with an imbalance of extracellular matrix (ECM) during tissue repair response, which can further deteriorate to hepatocellular carcinoma without timely treatment. Inhibiting activated hepatic stellate cell (HSC) proliferation and inducing apoptosis are the main methods for the treatment of liver fibrosis. In our previous study, we found that the TOA-glycine derivative (G-TOA) had exhibited more significant inhibitory activity against HepG2 cells and better hydrophilicity than TOA, ligustrazine (TMP), and oleanolic acid (OA). However, inhibiting activated HSC proliferation and inducing apoptosis by G-TOA had not been reported. In this paper, the selective cytotoxicity of G-TOA was evaluated on HSC-T6 cells and L02 cells, and apoptosis mechanisms were explored. It was found that G-TOA could selectively inhibit the proliferation of activated HSC-T6 cells, induce morphological changes, early apoptosis, and mitochondrial membrane potential depolarization, increase intracellular free calcium levels, downregulate the expression of NF-κB/p65 and COX-2 protein, and decrease the ratio of Bcl-2/Bax, thereby inducing HSC-T6 cell apoptosis. Thence, G-TOA might be a potential antifibrosis agent for the therapy of hepatic fibrosis, provided that it exerts anti-fibrosis effects on activated HSC-T6 cells.

Alfalfa (Medicago sativa L.) is the most commonly grown forage crop due to its better quality characteristics and high adaptability in China. However, there was 20%-80% hard seeds in alfalfa which could not be identified easily from non hard seeds which would cause the loss of seed utilization value and plant production. This experiment was designed for 121 samples of alfalfa. Seeds were collected according to different regions, harvested year and varieties. 31 samples were artificial matched as hard rates ranging from 20% to 80% to establish a model for hard seed rate by near infrared spectroscopy (NIRS) with Partial Least Square (PLS). The objective of this study was to establish a model and to estimate the efficiency of NIRS for determining hard rate of alfalfa seeds. The results showed that the correlation coefficient (R2(cal)) of calibration model was 0.981 6, root mean square error of cross validation (RMSECV) was 5.32, and the ratio of prediction to deviation (RPD) was 3.58. The forecast model in this experiment presented the satisfied precision. The proposed method using NIRS technology is feasible for identification and classification of hard seed in alfalfa. A new method, as nondestructive testing of hard seed rate, was provided to theoretical basis for fast nondestructive detection of hard seed rates in alfalfa.

Fiber-coupling surface Plasmon resonance sensor has attractive advantages of information transmission such as small volume, anti-electric magnetic field interference, and online real-time remote detection. In order to improve the performance of the sensor, the effect of the residual fiber thickness and the silver film thickness to the sensitivity of the sensor and the depth of the resonance peaks and full width ar half maximum (FWHM) are analyzed respectively. The results show that the increasing fiber residual thickness weakens the SPR phenomenon, and that the increasing silver film thickness widens the resonance peak, while the sensitivity of the sensor does not change monotonously. Through the integration of refractive index sensing sensitivity and full width at half maximum, figure of merit is presented and regarded as the optimized objective. The optimal design is achieved in the case of the fiber residual thickness for 66. 5 µm, and the silver film thickness for 50 nm. The optimized design with the figure of merit of 98. 67 is expected to be applied in the bio-chemical sensing and analysis.
ABSTRACT
Lower global cognitive function scores are a common symptom of autism spectrum disorders (ASDs). This study investigates the effects of melatonin on hippocampal serine/threonine kinase signaling in an experimental ASD model. We found that chronic melatonin (1.0 or 5.0 mg/kg/day, 28 days) treatment significantly rescued valproic acid (VPA, 600 mg/kg)-induced decreases in CaMKII (Thr286), NMDAR1 (Ser896), and PKA (Thr197) phosphorylation in the hippocampus without affecting total protein levels. Compared with control rats, the immunostaining of pyramidal neurons in the hippocampus revealed a decrease in immunolabeling intensity for phospho-CaMKII (Thr286) in the hippocampus of VPA-treated rats, which was ameliorated by chronic melatonin treatment. Consistent with the elevation of CaMKII/PKA/PKC phosphorylation observed in melatonin-treated rat, long-term potentiation (LTP) was enhanced after chronic melatonin (5.0 mg/kg) treatment, as reflected by extracellular field potential slopes that increased from 56 to 60 min (133.4 ± 3.9% of the baseline, P < 0.01 versus VPA-treated rats) following high-frequency stimulation (HFS) in hippocampal slices. Accordingly, melatonin treatment also significantly improved social behavioral deficits at postnatal day 50 in VPA-treated rats. Taken together, the increased phosphorylation of CaMKII/PKA/PKC signaling might contribute to the beneficial effects of melatonin on autism symptoms.

BACKGROUND: Almost all cases of cervical cancer can be attributed to human papillomavirus (HPV) infection. The loop electrosurgical excision procedure (LEEP) is widely used to treat HPV-mediated disease; thus, cervical cancer is highly preventable. However, LEEP does not necessarily clear HPV rapidly and may affect the accuracy of the results of ThinPrep cytology test (TCT) and cervical biopsy due to the formation of cervical scars. CASE SUMMARY: A 40-year-old woman underwent LEEP for cervical intraepithelial neoplasia grade 1 approximately 10 years ago. Subsequent standard cervical cancer screening suggested persistent HPV-52 infection, but TCT results were negative. Cervical biopsy under colposcopy was performed thrice over a 10-year period, yielding negative pathology results. She developed abnormal vaginal bleeding after sexual activity, persisting for approximately 1 year, and underwent hysteroscopy in our hospital. Histopathologic evaluation confirmed adenocarcinoma in situ of the uterine cervix. CONCLUSION: Patients with long-term persistent, high-risk HPV infection and negative pathology results of cervical biopsy after LEEP are at risk of cervical cancer. Hysteroscopic resection of cervical canal tissue is recommended as a supplement to cervical biopsy because it helps define the lesion site and may yield a pathologic diagnosis.
ABSTRACT
To investigate the effect of reduced early-pregnancy activated partial thrombin time (APTT), prothrombin time (PT), and international standardized ratio (INR) on the risk of preeclampsia. A total of 8549 pregnant women with singleton births were included. Early pregnancy APTT, PT, and INR levels, with age, birth, prepregnancy body mass index, fibrinogen (FBG), thrombin time (TT), D-dimer (DD2), antithrombin III (ATIII), fibrin degradation products (FDP) as confounders, generalized linear model of APTT, the relative risk of PT and INR when INR reduction. After adequate adjustment for confounders, the relative risk of preeclampsia was 0.703 for every 1 s increase in plasma PT results in early pregnancy, and for every 0.1 increase in plasma INR results, the relative risk of preeclampsia was 0.767. With a PT less than the P25 quantile (<11 s), the relative risk of preeclampsia was 1.328. The relative risk of preeclampsia at an INR less than the P25 quantile (<0.92) was 1.24. There was no statistical association between APTT on the risk of preeclampsia. The relative risk of preeclampsia is strongly associated with a decrease in PT and INR in early pregnancy. PT and INR in early pregnancy were a potential marker in the risk stratification of preeclampsia. Focusing on reduced PT and INR levels in early pregnancy can help to identify early pregnancies at risk for preeclampsia.

Intrauterine growth restriction (IUGR), when a fetus does not grow as expected, is associated with a reduction in hepatic functionality and a higher risk for chronic liver disease in adulthood. Utilizing early developmental plasticity to reverse the outcome of poor fetal programming remains an unexplored area. Focusing on the biochemical profiles of neonates and previous transcriptome findings, piglets from the same fetus are selected as models for studying IUGR. The cellular landscape of the liver is created by scRNA-seq to reveal sex-dependent patterns in IUGR-induced hepatic injury. One week after birth, IUGR piglets experience hypoxic stress. IUGR females exhibit fibroblast-driven T cell conversion into an immune-adapted phenotype, which effectively alleviates inflammation and fosters hepatic regeneration. In contrast, males experience even more severe hepatic injury. Prolonged inflammation due to disrupted lipid metabolism hinders intercellular communication among non-immune cells, which ultimately impairs liver regeneration even into adulthood. Additionally, Apolipoprotein A4 (APOA4) is explored as a novel biomarker by reducing hepatic triglyceride deposition as a protective response against hypoxia in IUGR males. PPARα activation can mitigate hepatic damage and meanwhile restore over-expressed APOA4 to normal in IUGR males. The pioneering study offers valuable insights into the sexually dimorphic responses to hepatic injury during IUGR.

Normal pregnancy is a hypercoagulable state with an increase in coagulation factor levels and a decrease in natural anticoagulation. However, a higher hypercoagulable state with prolonged activated partial thromboplastin time (APTT), prothrombin time (PT), increased D-dimer, and mean platelet volume is seen in women with preeclampsia at the time of onset. In addition, endothelial dysfunction occurs before the clinical symptoms of preeclampsia. Therefore, we undertook this study to investigate the coagulation profile in the first trimester in women who developed preeclampsia later. A total of 853 pregnant women with singleton births at the Obstetrics and Gynecology Hospital of Fudan University between January 2021 and December 2021 were included in this case-control study. In the comparison with the controls (n = 531), the mean value of D-dimer, APTT, thrombin time (TT), antithrombin (AT)), and fibrin degradation products (FDP) was significantly lower in preeclamptic women at the time of diagnosis (n = 322). The changes in the coagulation profile were not associated with the severity or the time of onset. The reduced values of D-dimer, AT, and FDP, and increased values of TT were also observed in the first trimester in women who developed preeclampsia later and were not associated with the severity, or the time of onset of preeclampsia. After adjusting for maternal age and BMI, the values of D-dimer and AT in the first trimester were correlated to the risk of developing preeclampsia. Our findings suggest that there is an abnormal maternal response to the hemostatic system in early gestational age in women who developed preeclampsia later and measuring the coagulation profile could be an additional predictive marker of preeclampsia.
ABSTRACT
Weaning is an important period that affects the performance of piglets. However, the regulation of dietary amino acid levels is considered to be an effective way to alleviate the weaning stress of piglets. N-carbamylglutamate (NCG) plays an important role in improving the growth performance and antioxidant capacity of animals. A total of 36 weaned piglets were randomly assigned to two treatment groups, a control group (CON) and a 500 mg/kg NCG group (NCG), and the experiment lasted for 28 days. The results show that the NCG treatment group showed an increased 0-28 days average weight gain and average daily feed intake, and also increased contents of GLU and HDL, and lower SUN in serum, and an upregulation of the expression of the amino acid transporters SNAT2, EAAC1, SLC3A1, and SLC3A2 mRNA in the jejunum (p < 0.05), as well as an increased villus length and VH:CD ratio, and claudin-1, occludin, and ZO-1 mRNA expression in the jejunum (p < 0.05). The NCG treatment group showed an increased content of GSH-Px in serum and T-AOC and SOD in the jejunum, and a lower content of MDA (p < 0.05); and the upregulation of the mRNA expression related to antioxidant enzymes (CAT, SOD1, Gpx4, GCLC, GCLM and Nrf2, AhR, CYP1A1) in the jejunal mucosa (p < 0.05). In addition, compared with the control group, the NCG treatment group saw an upregulation in the mRNA expression of IL-10 and a decrease in the expression of IL-1ß and IL-4 in the jejunal mucosa (p < 0.05). In summary, the results of this study suggest that NCG improved growth performance and jejunal morphology, improved the jejunal transport of amino acids related to the ornithine cycle, and improved the antioxidant capacity in weaned pigs.
ABSTRACT
Objectives: Cognitive impairment is common and linked to poor outcomes in patients with late-onset depression (LOD). The cognitive effects of repetitive transcranial magnetic stimulation (rTMS) for LOD are not well understood. This study aimed to investigate the effects of rTMS on cognitive function in elderly patients with LOD. Methods: In total, 58 elderly patients (aged 60 to 75 years) with depression were enrolled and randomly assigned to an active rTMS group or a sham group. The participants received active or sham rTMS over the left dorsolateral prefrontal cortex for 4 weeks, 5 days a week, at a frequency of 10 Hz rTMS and 120% of the motor threshold (MT). Cognitive function was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) at baseline, the end of the 4 week treatment period, and at the 4 week follow-up. Results: The active rTMS group showed significant improvements in immediate memory and attention scores on the RBANS compared to the sham group. However, no significant differences were observed between the two groups in other cognitive domains assessed by the RBANS. No serious adverse events related to rTMS treatment were observed. Conclusion: Treatment with 120% MT rTMS was associated with improvement in cognitive defects related to the active phase of LOD. These findings suggest that rTMS could provide early improvements in cognitive function in clinical settings for elderly patients with LOD.Clinical trial registration: https://www.chictr.org.cn/showproj.html?proj=40698, identifier ChiCTR1900024445.
