Meta-analysis comparing different ultrasound detection methods to accurately assess wound healing and scar formation after caesarean section.

The accurate assessment of wound healing post-caesarean section, especially in twin pregnancies, remains a pivotal concern in obstetrics, given its implications for maternal health and recovery. Traditional methods, including conventional abdominal ultrasonography (CU), have been challenged by the advent of transvaginal ultrasonography (TU), offering potentially enhanced sensitivity and specificity. This meta-analysis directly compares the efficacy of TU and CU in evaluating wound healing and scar formation, crucial for optimizing postoperative care. Results indicate that TU is associated with significantly better outcomes in wound healing, demonstrated by lower REEDA scores (SMD = -20.56, 95% CI: [-27.34.20, -13.77], p < 0.01), and in scar formation reduction, evidenced by lower Manchester Scar Scale scores (SMD = -25.18, 95% CI: [-29.98, -20.39], p < 0.01). These findings underscore the potential of integrating TU into routine post-caesarean evaluation protocols to enhance care quality and patient recovery.

Identification and bioinformatics analysis of differentially expressed milk exosomal microRNAs in milk exosomes of heat-stressed Holstein cows.

In summer, heat stress is one of the primary reasons for the compromised health and low milk productivity of dairy cows. Hyperthermia affects milk synthesis and secretion in the mammary glands of dairy cows. As molecules for intercellular communication, milk-derived exosomes carry genetic material, proteins, and lipids, playing a crucial role in mammary tissue growth and milk synthesis in dairy cows. The aim of this study was to explore the milk exosomal miRNA profile of heat-stressed and normal Holstein cows. We isolated and identified milk exosomes to screening for differentially expressed miRNAs using small RNA sequencing. Then, TargetScan and miRanda algorithms were used to predict the putative targets of the differentially expressed miRNAs, whereas GO and KEGG pathway enrichment analyses were performed for the differentially expressed miRNA-target genes. Our results showed that 215 miRNAs were significantly differentially expressed in heat-stressed milk exosomes, of which one was upregulated and 214 were significantly downregulated. GO and KEGG enrichment analyses indicated that differentially expressed miRNAs might play a role in apoptosis, autophagy, and the p38 MAPK pathway. qRT-PCR assay verified that the expression of miRNAs was consistent with the sequencing results, warranting further verification of their specific targets of action. In conclusion, changes in the miRNA expression profile of milk exosomes indicated the role of exosomal miRNAs in regulating heat stress resistance and apoptosis in dairy cows. Our results suggested that milk-derived exosomal miRNAs could increase mammary gland resistance to heat stress, thereby enhancing milk synthesis in dairy cows.

Gut-derived fungemia due to Kodamaea ohmeri combined with invasive pulmonary aspergillosis: a case report.

BACKGROUND: Kodamaea ohmeri is a rare pathogen with high mortality and is found among blood samples in a considerable proportion; however, gastrointestinal infection of K. ohmeri is extremely rare. Invasive pulmonary aspergillosis is also an uncommon fungal; these two fungal infections reported concomitantly are unprecedented. CASE PRESENTATION: We described a case of a 37-year-old male who got infected with K. ohmeri and invasive pulmonary aspergillosis. We used the mass spectrometry and histopathology to identify these two fungal infections separately. For the treatment of K. ohmeri, we chose caspofungin. As for invasive pulmonary aspergillosis, we used voriconazole, amphotericin B, and then surgery. The patient was treated successfully through the collaboration of multiple disciplines. CONCLUSIONS: We speculate that the destruction of the intestinal mucosa barrier can make the intestine one of the ways for certain fungi to infect the human body.

First report of a stunt nematode Tylenchorhynchus zeae on corn in Gansu Province, China.

During a survey of plant parasitic nematodes in 2019, at Gansu Province, China, the stunt nematode Tylenchorhynchus zeae was found parasitizing corn seedlings. Females, males and juveniles of T. zeae were observed on soil and roots samples of corn after processing and extraction. This population of stunt nematodes was identified based on morphological and by sequencing the ITS1 region of rDNA and D2/D3 fragments of the 28 S rRNA. The ITS1 and the D2/D3 sequences of this population, shared 99.00 to 99.05% and 99.43 to 99.73% of similarity with sequences corresponding to T. zeae in GenBank, respectively. This is the first report of T. zeae infecting corn in Gansu Province, northwest China.During a survey of plant parasitic nematodes in 2019, at Gansu Province, China, the stunt nematode Tylenchorhynchus zeae was found parasitizing corn seedlings.

Chemerin induces lipolysis through ERK1/2 pathway in intramuscular mature adipocytes of dairy bull calves.

The adipokine Chemerin has been reported to regulate differentiation and metabolism of adipocytes, but the mechanism underlying lipolysis is still largely unknown. The purpose of this study was to explore whether ERK1/2 pathway is involved in regulating Chemerin during bovine intramuscular mature adipocyte lipolysis. Intramuscular mature adipocytes of dairy bull calves were cultured in vitro and were treated with Chemerin or U0126, which is an inhibitor of ERK1/2 pathway. The results showed that TG content in cells was significantly decreased, glycerol and free fatty acid were significantly increased in cell culture media, and the expression of phosphorylated ERK1/2 in cells was increased in Chemerin-treated group, suggested that ERK1/2 pathway was involved in regulation of lipolysis by Chemerin. In addition, the expression of lipolytic-related critical factors ATGL, HSL, LPL, PPARα, UCP3, and CPT1 were upregulated, but the expression of adipogenic key factors, including PPARγ and C/EBPα were downregulated by Chemerin. Interestingly, all the effects of Chemerin on genes expression in intramuscular mature adipocytes or fat tissue were inhibited by U0126, showed that the function of Chemerin to promote adipose decomposition will be significantly weakened if the ERK1/2 pathway is suppressed, and confirmed that ERK1/2 pathway is involved in mediate Chemerin-enhanced lipolysis. In conclusion, the study demonstrated that Chemerin induce intramuscular mature adipocytes lipolysis through activation of the ERK1/2 pathway. Our research at least provide partial mechanisms of Chemerin on lipolysis and deposition of intramuscular fat tissue of dairy bull calves.

Effects of ulinastatin on early postoperative cognitive function after one-lung ventilation surgery in elderly patients receiving neoadjuvant chemotherapy.

We investigated the effects of ulinastatin on early postoperative cognitive dysfunction (POCD) after one-lung ventilation (OLV) surgery in elderly patients receiving neoadjuvant chemotherapy. Eighty elderly patients with preoperative neoadjuvant chemotherapy scheduling for radical esophagectomy under OLV were recruited. They were randomly divided into an ulinastatin pretreatment group (U group, n = 40) and a control group (C group, n = 40). The U group received 10,000 U/kg ulinastatin before anesthesia and 5000 U/kg daily on postoperative days 1 to 3, while C group received saline. Levels of interleukin (IL)-6, IL-10, C-reactive protein (CRP), and S-100ß protein were assayed before surgery, at the end of surgery, and on postoperative days 1 and 3. Patients underwent cognitive assessment 1 day before and 7 days after surgery. 38 patients in U group and 37 patients in C group completed the neuropsychological tests. The U group had a lower incidence of POCD than C group (23.7 % versus 45.9 %, P = 0.043). The levels of S-100ß protein, IL-6, IL-10, and CRP in both groups increased after surgery. The postoperative concentrations of S-100ß protein, IL-6, and CRP in U group were lower than those in C group. On postoperative day 3, compared with C group, the level of CRP in U group was lower, while that of IL-10 was higher. These findings demonstrate that ulinastatin can attenuate the elevation of S100ß protein levels and the incidence of POCD, most likely by the mechanism of reducing serum IL-6 and CRP levels and increasing IL-10 levels.

Efficacy Evaluation of Seed-Coating Compounds Against Cereal Cyst Nematodes and Root Lesion Nematodes on Wheat.

Cereal cyst nematodes (Heterodera avenae and H. filipjevi) and root lesion nematodes (Pratylenchus spp.) have been found to infect cereals in 16 provinces of China. To develop a nematicide that effectively controls nematodes, two novel chemical products, methylene bis thiocyanate (MBT) and MBT + thiamethoxam (MTT); four common pesticides, fipronil + chlorpyrifos (FIC), emamectin benzoate, imidacloprid, and Bacillus thuringiensis; and one fungicide, iprodione, were tested as seed coatings for the control of cereal cysts and root lesion nematodes from 2013 to 2015. Wheat seeds were treated with these seven seed coatings before sowing, and changes in the numbers of Heterodera spp. and Pratylenchus spp. were recorded during three different growth stages. Wheat yields were also compared after harvest. All treatments reduced the numbers of Pratylenchus in wheat and of cysts and eggs of Heterodera in the soil compared with the untreated control. Among the treatments, application of MTT or FIC was more effective than that of the other treatments for nematode control, and the other treatments had similar effects. The results of this study have demonstrated that MTT and FIC applied as seed treatments effectively reduce the number of cysts, inhibit the reproduction of Heterodera and Pratylenchus, and enhance wheat yields. MTT and FIC are thus suitable for controlling nematodes on wheat under natural field conditions.

The adipokine Chemerin induces lipolysis and adipogenesis in bovine intramuscular adipocytes.

The adipokine Chemerin is reported to regulate adipogenesis and glucose homeostasis in vivo and in 3T3-L1 cells. Our team is focused on the role of Chemerin in metabolism and intramuscular adipocyte differentiation because intramuscular fat is the basic material for the formation of marbling in livestock and poultry meat. In this study, bovine intramuscular mature adipocytes were cultured in medium with Chemerin, and the process of lipolysis of mature adipocytes and the adipogenesis of de-differentiated preadipocytes were investigated. The results showed that Chemerin induced significant lipolytic metabolism in intramuscular mature adipocytes, indicated by increased levels of glycerol, FFA, and up-regulated expression of the lipolysis critical factors HSL, LPL, and leptin. Meanwhile, the expressions of adipogenic key factors PPARγ, C/EBPα, and A-FABP were decreased by Chemerin during lipolysis or dedifferentiation in mature adipocytes. The de-differentiated preadipocytes could re-differentiate into mature adipocytes. Intriguingly, the formation of cells' lipid droplets was promoted by Chemerin during preadipocyte differentiation. In addition, mRNA and protein expressions of PPARγ, C/EBPα, and A-FABP were up-regulated by Chemerin during preadipocytes differentiation. These results suggest that Chemerin promotes lipolysis in mature adipocytes and induces adipogenesis during preadipocyte re-differentiation, further indicating a dual role for Chemerin in the deposition of intramuscular fat in ruminant animals.

Cytoprotection of methionine on hyperthermia-induced damage in bovine mammary epithelial cells.

The protective effects of methionine against hyperthermia-induced damage in bovine mammary epithelial cells (BMEC) were studied. We have investigated the effects of methionine on proliferation, antioxidant activity, and apoptosis of the mammary epithelial cells of dairy cow after heat treatment. The structure of BMEC membrane was damaged by hyperthermia. Methionine (30 and 60 mg/L) efficiently increased cell viability and attenuated morphological damages in hyperthermia-treated BMEC. It significantly reduced lactate dehydrogenase leakage and malondialdehyde formation, whereas superoxide dismutase activity increased significantly. It also increased cell survival and decreased early apoptosis. Methionine therefore is cytoprotective on hyperthermia-induced damage in BMEC by increasing intracellular antioxidant levels and decreasing lipid peroxidation.

The protective effect of rosmarinic acid on hyperthermia-induced C2C12 muscle cells damage.

High temperature will cause animal tissues or cells damage. Rosmarinic acid (RA) is a good antioxidant and health care product, but the roles of RA in muscle cells damage and the mechanisms which caused by high temperature is still unknown. In this study, the roles of RA on hyperthermia-induced apoptosis and damage of C2C12 muscle cells were investigated. C2C12 cells were cultured in medium with different concentration (0, 25, 50, 100 µM) RA and treated in 42 °C high temperature to induce cellular apoptosis and damage. Then, these cells were analyzed effect of different dose of RA on cells apoptosis and damage. The results indicated that RA has protective effect on heat-stress induced cellular damage, and the cells have the higher cell viability at the dose of 50 µM RA by MTT assay. Hochest33342/PI double staining showed that the cellular apoptosis of C2C12 cells were decreased in the presence of selected 50 µM RA. Malondialdehyde formation and reactive oxygen species levels were also decreased significantly, but cellular superoxide dismutase activity was increased significantly in the presence of RA even in the condition of 42 °C. Meanwhile, Caspase-3 mRNA expression, Caspase-3 activity, and Bax/Bcl-2 ratio were reduced significantly, but the mRNA expression of Hsp72 was increased significantly in those hyperthermia-induced C2C12 cells in the presence of 50 µM RA. Taken together, the results at least discovered that RA has protective effects on hyperthermia-induced cellular apoptosis and damage of muscle cells by change the expression of stress-genes and increasing intracellular antioxidant capability.

Transcriptome Analysis in High Temperature Inhibiting Spermatogonial Stem Cell Differentiation In Vitro.

As one of the factors of male infertility, high temperature induces apoptosis of differentiated spermatogenic cells, sperm DNA oxidative damage, and changes in morphology and function of Sertoli cells. Spermatogonial stem cells (SSCs) are a type of germline stem cells that maintain spermatogenesis through self-renewal and differentiation. At present, however, the effect of high temperature on SSC differentiation remains unknown. In this study, an in vitro SSC differentiation model was used to investigate the effect of heat stress treatment on SSC differentiation, and RNA sequencing (RNA-seq) was used to enrich the key genes and pathways in high temperature inhibiting SSC differentiation. Results show that 2 days of 37 °C or 43 °C (30 min per day) heat stress treatment significantly inhibited SSC differentiation. The differentiation-related genes c-kit, stra8, Rec8, Sycp3, and Ovol1 were down-regulated after 2 and 4 days of heat stress at 37 °C. The transcriptome of SSCs was significantly differentially expressed on days 2 and 4 after heat stress treatment at 37 °C. In total, 1660 and 7252 differentially expressed genes (DEGs) were identified by RNA-seq in SSCs treated with heat stress at 37 °C for 2 and 4 days, respectively. KEGG pathway analysis showed that p53, ribosome, and carbon metabolism signaling pathways promoting stem cell differentiation were significantly enriched after heat stress treatment at 37 °C. In conclusion, 37 °C significantly inhibited SSC differentiation, and p53, ribosome, and carbon metabolism signaling pathways were involved in this differentiation inhibition process. The results of this study provide a reference for further investigation into the mechanism by which high temperature inhibits SSC differentiation.

Identification of porcine adipose progenitor cells by fluorescence-activated cell sorting for the preparation of cultured fat by 3D bioprinting.

Cultured meat is an emerging technology that is friendly for the environment and animal welfare. As a novel food ingredient, cultured fat is essential for the flavor and nutrition of cultured meat. In this study, we purified adipose progenitor cell (APC) from freshly isolated porcine stromal vessel fraction (SVF) by fluorescence-activated cell sorting (FACS) and identified the transcriptome characteristics of APC by RNA sequencing (RNA-seq). The results showed that APC had characteristics of high-efficiency proliferation and adipogenic differentiation and was distinct from SVF cell in transcriptome profiles. Subsequently, APC was used to prepare cultured fat by 3D bioprinting and to evaluate the differences in fatty acid composition between cultured fat and porcine subcutaneous adipose tissue (pSAT). The results indicated that the fatty acid composition and content of cultured fat had a certain similarity with pSAT; specifically, the content of key monounsaturated fatty acid (MUFA) that create pork flavor in cultured fat, such as C18:1(n-12), C18:1(n-9) and C19:1(n-9)T, were close to that of pSAT. Therefore, this research indicated that APC is a promising candidate cell type for the production of cultured fat.

Melatonin prevents cyclophosphamide-induced primordial follicle loss by inhibiting ovarian granulosa cell apoptosis and maintaining AMH expression.

Cyclophosphaty -45mide (Cyc) chemotherapy in young female cancer patients is associated with an increased risk of premature ovarian insufficiency (POI). This study was designed to investigate the protective role of melatonin (Mel) as an adjuvant against Cyc-induced POI. Female mice received a single intraperitoneal (i.p.) dose of Cyc (75 mg/kg). Mel protection was achieved in mice after i.p. injection of melatonin (50 mg/kg) every 24 h for four consecutive days prior to chemotherapy initiation and for 14 additional days. Ovarian reserve testing, hormonal assays for follicle-stimulating hormone, luteinizing hormone, and anti-Müllerian hormone (AMH), assessment of the oxidative stress status, and measurement of the relative expression of genes in PTEN/AKT/FOXO3a and mitochondrial apoptosis pathways were performed. The results showed that treatment with 50 mg/kg Mel significantly prevented Cyc-induced over-activation of primordial follicles by maintaining the plasma level of AMH and subsequently preventing litter size reduction in mice treated with Cyc chemotherapy. Importantly, Mel treatment significantly prevented ovarian granulosa cell loss by inhibiting the mitochondrial apoptotic pathway. Identifying the protective actions of Mel against Cyc-induced primordial follicle loss has important implications for fertility maintenance in young cancer patients undergoing chemotherapy.

Patient and methods: Clinical data of a patient diagnosed with poorly differentiated GAC admitted to the department of oncology of the Lanzhou University Second Hospital were retrospectively analyzed. The patient underwent four PDT procedures combined with chemo-, targeted, and immunotherapy. Results: A 72-year-old male patient received combination therapy of PDT. This treatment resolved the cancerous tissues and levels of tumor markers. There was no recurrence and metastasis during a 7-month follow-up. Conclusions: Combination therapy of PDT can effectively treat tumors and may be a method suitable for elderly patients with advanced GAC.

Effects of selected flavonoids oncellproliferation and differentiation of porcine muscle stem cells for cultured meat production.

Stemness decline of muscle stem cells (MuSCs) is a significant problem in cultured meat processing. In the present study, three flavonoids (quercetin, icariin, and 3,2'-dihydroxyflavone) with multi concentrations were evaluated to promote the proliferation and differentiation of porcine muscle stem cells. In the proliferation phase, 3,2'-dihydroxyflavone (10 µM) significantly amplified the cells by 34% and up-regulated the expression of paired box transcription factor 7 (PAX7) by 60%, which was higher than quercetin (75 nM) and icariin (7.5 nM). In the differentiation phase, quercetin (50 nM) showed the best pro-differentiation effect and up-regulated the expression of myosin heavy chain (MYHC) by 4.73-fold compared with the control group. These results indicated that flavonoids had a significant impact on promoting the proliferation and differentiation of porcine MuSCs, and 3,2'-dihydroxyflavone (10 µM) for proliferation and quercetin (50 nM) for differentiation were the optimal combinations.

Production of cultured fat with peanut wire-drawing protein scaffold and quality evaluation based on texture and volatile compounds analysis.

Cultured meat is an emergent technology that cultivates cells in three-dimensional scaffolds to generate tissue for consumption. Fat makes an important contribution to the flavor and texture of traditional meat, but there are few reports on cultured fat. Here, we demonstrated the construction of cultured fat by inoculating porcine adipose-derived mesenchymal stem cell (ADSC) on peanut wire-drawing protein (PWP) scaffolds. First, we demonstrated that basic fibroblast growth factor (bFGF) promoted cell proliferation and maintained adipogenic differentiation ability. Then, we generated cultured fat and found that cultured fat decreased the texture of PWP scaffolds. Moreover, 43 volatile compounds were detected by headspace gas chromatography-ion mobility spectrometry (GC-IMS), of which 17 volatile compounds showed no significant differences between cultured fat and porcine subcutaneous adipose tissue (pSAT), which indicated that cultured fat and pSAT had certain similarities. Collectively, this research has great promise for improving the quality of cultured meat.

Efficacy of acupuncture based on acupoint combination theory for irritable bowel syndrome: a study protocol for a multicenter randomized controlled trial.

BACKGROUND: Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder characterized by abdominal pain, diarrhea or constipation, and changes in defecation patterns. No organic disease is found to explain these symptoms by routine clinical examination. This study aims to investigate the efficacy and safety of acupuncture therapy for IBS patients compared with those of conventional treatments. We also aim to identify the optimal acupoint combination recommended for IBS and to clarify the clinical advantage of the "multiacupoint co-effect and synergistic effect." METHODS AND ANALYSIS: A total of 204 eligible patients who meet the Rome IV criteria for IBS will be randomly stratified into acupuncture group A, acupuncture group B, or the control group in a 1:1:1 ratio with a central web-based randomization system. The prespecified acupoints used in the control group will include bilateral Tianshu (ST25), Shangjuxu (ST37), Neiguan (PC6), and Zusanli (ST36). The prespecified acupoints used in experimental group A will include bilateral Tianshu (ST25), Shangjuxu (ST37), and Neiguan (PC6). The prespecified acupoints used in experimental group B will include bilateral Tianshu (ST25), Shangjuxu (ST37), and Zusanli (ST36). Each patient will receive 12 acupuncture treatments over 4 weeks and will be followed up for 4 weeks. The primary outcome is the IBS-Symptom Severity Scale (IBS-SSS) score. The secondary outcomes include the Bristol Stool Form Scale (BSFS), Work and Social Adjustment Score (WSAS), IBS-Quality of Life (IBS-QOL), Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS) scores. Both the primary outcome and the secondary outcome measures will be collected at baseline, at 2 and 4 weeks during the intervention, and at 6 weeks and 8 weeks after the intervention. ETHICS AND DISSEMINATION: The entire project has been approved by the ethics committee of the Beijing University of Chinese Medicine (2020BZYLL0903). DISCUSSION: This is a multicenter randomized controlled trial for IBS in China. The findings may shed light on the efficacy of acupuncture as an alternative to conventional IBS treatment. The results of the trial will be disseminated in peer-reviewed publications. TRIAL REGISTRATION: Chinese Clinical Trials Register ChiCTR2000041215 .

The protective effect of rosmarinic acid on myotube formation during myoblast differentiation under heat stress.

High ambient temperature is one of the most important environmental factors that caused the reduction of livestock productivity and the increase of mortality. It has been shown that heat stress could affect the meat quality characteristics by physiological and metabolic perturbations in live livestock. Rosmarinic acid (RA) is a natural polyphenolic phytochemical compound that has many important biological activities, such as antioxidant, antimutagenic, and antitumor. The purpose of this study was to investigate the possible function and mechanism of RA on myoblast proliferation and differentiation under heat stress condition. The results showed that heat stress reduced the viability of myoblast and increased the percentage of apoptotic cells, and it also disrupted myotube formation by altering the expression of myogenic regulatory factors MyoD, myogenin, and MyHC. However, pretreatment of RA can protect C2C12 cells from heat stress-induced apoptosis, and it also increased the expression level of MyoD, myogenin, and MyHC under heat stress, which indicated that RA have protective effect on heat stress-caused failure of myotube formation during myoblast differentiation. Above all, our finding demonstrated that RA can promote the differentiation of C2C12 myoblast and maintain the formation of myotubes even under heat stress condition.

Precise diagnosis of Neisseria macacae infective endocarditis assisted by nanopore sequencing.

Infective endocarditis caused by Neisseria macacae in humans is extremely rare. We presented here a case of N. macacae infective endocarditis in a 61-year-old man with a native aortic valve infection. N. macacae was isolated from blood culture and was detected by nanopore-based metagenomic sequencing in the vegetations. Finally, the patient recovered completely after surgery and antibiotic therapy.

Hypertriglyceridemia-induced acute pancreatitis: progress on disease mechanisms and treatment modalities.

Acute pancreatitis (AP) is a common and destructive inflammatory condition of the pancreas. Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) has become the second major cause of AP. Although the association between HTG and AP is well established, HTG as a risk factor of AP in the general population is not well identified. In this review, we summarize recent progress in our understanding of the pathogenesis of HTG-AP and clinical management of this disease. The mechanism responsible for HTG-AP is related to high-level free fatty acid (FFA), microcirculatory disorder, oxidative stress, Ca2+ overload, and genetic polymorphism. Heparin and insulin therapy in diabetic patients with HTG can dramatically reduce triglyceride levels. Use of plasmapheresis is still experimental and better-designed studies are needed to evaluate the promise in the management of HTG-AP. Dietary intervention, lifestyle changes, and control of secondary causes are critical to the management and treatment of HTG-AP.
