Self-assembled and Zn(II)-coordinated dipeptide nanoparticles with membrane-rupturing action on bacteria.

Metal ion-coordinated self-assembled short-chain amino acid peptide molecules with multi-photon excitation wavelengths and their photoluminescence properties are advantageous for fluorescence-based diagnostics and treatments of biological diseases based on their extra features of antibacterial agents. We have designed a novel strategy based on tryptophan molecule coordinated with Zn(II) ions in the form of biocompatible spherical nanoparticles of diameter 30-80 nm which have been used for antibacterial treatments against different kinds of pathogenic bacteria (Escherichia coli, Salmonella typhimurium, and Pseudomonas). Preferably, we have used tryptophan-phenylalanine (Trp-Phe), a dipeptide molecule having tryptophan as principal material against E. coli strains as antimicrobial agents for surface rupturing and killing purposes. Furthermore, based on single amino acid, tryptophan, self-assembled and Zn(II)-coordinated dipeptide nanoparticles (Zn-DPNPs) were studied against three types of multi-drug-resistant bacteria as an active antimicrobial agent. These antibacterial efficient nanoparticles may have best alternative of antibiotic drugs for clinical applications. The capability of self-assembled fluorescence behavior of Zn-coordinated dipeptide molecules and higher hydrophobicity against bacterial cell wall will perform as antimicrobial fluorescent agents. KEY POINTS: • Zn(II) and Cu(II) better coordinated into self-assembled NPs. • Fluorescence signals showed interaction of NPs with gram -ve cell wall. • Significant surface-damaging effects were observed in the case of Cu-DPNPs and Zn-DPNPs.

[A Case of Intractable Pyogenic Spondylitis Due to Suture Failure and MRSA Infection Secondary to Surgery for Ascending Colon Cancer].

A 79-year-old man diagnosed with ascending colon cancer underwent laparoscopic right hemicolectomy(Stage Ⅱ). Postoperatively, suture failure occurred on Day 5 and was alleviated with conservative therapy. However, on Day 23, he was diagnosed with MRSA-induced sepsis with a body temperature of 39 °C. After administration of vancomycin, his general conditions stabilized, although intermittent low-grade fever and a high C-reactive protein(CRP)level persisted. Although the source of the infection could not be easily identified, he was diagnosed with suppurative spondylitis after lumbar MRI examination on Day 43. The CRP level was normalized with long-term administration of antibiotics and the symptoms were gradually improved with rehabilitation. The patient was discharged after approximately 4 months and could walk without assistance 8 months postoperatively. In this case, purulent spondylitis may have occurred via hematogenous infection due to the suture failure after surgery for ascending colon cancer. Purulent spondylitis is a relatively rare disease. However, it may lead to the patient requiring long-term treatment and cause serious sequelae. Therefore, it is important to keep this disease in mind when treating patients with postoperative fever of unknown origin or aggravating lower back pain.

Targeting miR-10a-5p/IL-6R axis for reducing IL-6-induced cartilage cell ferroptosis.

BACKGROUND: Intervertebral disc degeneration (IDD) causes lower back pain, and is often accompanied with robust inflammation. However, whether inflammation plays a role in IDD remains controversial, and the mechanism is ill-elucidated. METHODS: Cartilage specimens from patients with scoliosis (control) and IDD were examined for IL-6 and its receptor expression by qPCR and western blot. Primary human articular chondrocyte was employed as a model for in vitro assessment of IL-6 effects in cell viability, cellular oxidative stress and iron homeostasis by MTT, MDA, ROS and Iron Colorimetric assays. The underlying mechanism was explored by qPCR, western blot, RIP in combination with bioinformatics analysis. RESULTS: We found in this study that IL-6 and its receptor were aberrantly expressed in cartilage tissues of IDD patients. IL-6 down-regulated miR-10a-5p, which subsequently derepressed IL-6R expression. IL-6 exposure caused cartilage cell ferroptosis by inducing cellular oxidative stress and disturbing iron homeostasis. Overexpressing miR-10a-5p suppressed IL-6R expression, and partially abolished IL-6-induced ferroptosis. CONCLUSION: Results from current study suggests that inflammatory cytokine IL-6 appeared in IVD aggravates its degeneration by inducing cartilage cell ferroptosis. This is caused partially by inhibiting miR-10a-5p and subsequently derepressing IL-6R signaling pathway. Our study provides a novel mechanism explaining inflammatory cytokine-caused cartilage cell death in degenerative IVD, and makes IL-6/miR-10a-5p/IL-6R axis a potential therapeutic target for intervention of IDD.

[A Fatal Case of Meningeal Carcinomatosis in a Rectal Cancer Patient Diagnosed with Pathologic Complete Response after Neoadjuvant Chemoradiotherapy].

A 48-year-old man visited our hospital complaining of abdominal pain constipation and mucous bloody stool. He was diagnosed rectal cancer with remarkable local infiltration in the pelvic organs and no distant metastasis. The pathological diagnosis was poorly differentiated adenocarcinoma and signet ring cell carcinoma. He was administered neoadjuvant chemoradiotherapy(45 Gy/30 Fr, S-1 100 mg/day 2-weeks administration, 1-week withdrawal)and underwent abdominal perineal rectal amputation. No cancer cells remained in the excised organs, so he was diagnosed with pathologic complete response(pCR). The serum CEA level decreased from 35.1 to 5.9 ng/mL at this point. Due to recurrence of peritoneal dissemination during postoperative adjuvant chemotherapy(CapeOX), the regimen was changed to FOLFIRI plus Pmab. After 4 courses of FOLFIRI plus Pmab, he complained dizziness and headache. Therefore, head computed tomography and magnetic resonance imaging were performed. However, there were no abnormal findings. An evaluation of his cerebrospinal fluid resulted in a diagnosis of meningeal carcinomatosis by fluid cytology(adenocarcinoma/class Ⅴ). His medical condition worsened rapidly and he ultimately died 2.5 months after the onset of his headache. The serum CEA level ultimately reached 2,992.6 ng/mL. The patient had been deemed to have pCR following the administration of neoadjuvant chemoradiation and surgery. His serum CEA level had increased continuously during the early period of postoperative chemotherapy without any abdominal imaging or neurological findings. After the onset of the primary symptoms of meningeal carcinomatosis, his condition deteriorated rapidly. When we encounter patients with colorectal cancer, especially those with poorly differentiated adenocarcinoma, and a continuously increasing CEA level despite no remarkable findings, we should suspect meningeal carcinomatosis and perform further examinations, including sampling the cerebrospinal fluid.

Super-resolution imaging reveals changes in Escherichia coli SSB localization in response to DNA damage.

The E. coli single-stranded DNA-binding protein (SSB) is essential to viability. It plays key roles in DNA metabolism where it binds to nascent single strands of DNA and to target proteins known as the SSB interactome. There are >2,000 tetramers of SSB per cell with 100-150 associated with the genome at any one time, either at DNA replication forks or at sites of repair. The remaining 1,900 tetramers could constantly diffuse throughout the cytosol or be associated with the inner membrane as observed for other DNA metabolic enzymes. To visualize SSB localization and to ascertain potential spatiotemporal changes in response to DNA damage, SSB-GFP chimeras were visualized using a novel, super-resolution microscope optimized for the study of prokaryotic cells. In the absence of DNA damage, SSB localizes to a small number of foci and the excess protein is associated with the inner membrane where it binds to the major phospholipids. Within five minutes following DNA damage, the vast majority of SSB disengages from the membrane and is found almost exclusively in the cell interior. Here, it is observed in a large number of foci, in discreet structures or, in diffuse form spread over the genome, thereby enabling repair events.

[Study on anti-osteoporosis effect of Eucommiae Cortex based on GC-MS metabonomics].

Based on GC-MS metabolomics and biochemical index analysis, the mechanism of bone mass loss in osteoporosis and the evaluation of anti-osteoporosis in Eucommiae Cortex were studied. The OVX rats model was established by bilateral ovariectomized. The routine indexes such as BMC, BMD, BGP and TRAP5 b were determined. The GC-MS technique was used to analyze the metabolism profile of serum samples between the control group, model group and medicine group, and multiple statistical analysis methods including principal component analysis(PCA), partial least squares-linear discriminant analysis(PLS-LDA) and subwindow rearrangement analysis(SPA) were used to screen and identify biomarkers. Five metabolites were selected as potential biomarkers, glycine, lysine, tryptophan, docosahexaenoic acid and glucose. Except for the significant increase of tryptophan in serum of OVX rats, the other four metabolites were significantly decreased. Moreover, the five biomarkers of the medicine group had a trend of returning to rats in control group. The significantly altered metabolite levels indicated that Eucommiae Cortex may relieve the symptoms of osteoporosis by regulating amino acid metabolism and oxidative stress.

[Effect of butyl alcohol extract of Baitouweng Decoction on epithelial barrier of vaginal mucosa in mice with vulvovaginal candidiasis].

To investigate the effect of butyl alcohol extract of Baitouweng Decoction(BAEB) on the epithelial barrier of vaginal mucosa in mice with vulvovaginal candidiasis(VVC). Seventy-two female SPF Kunming mice were randomly divided into blank group, VVC model group, fluconazole group, and BAEB treatment groups(high, middle and low dose groups). Estradiol benzoate was injected subcutaneously qd alt, and Candida albicans(2×10~6 CFU·mL~(-1)) was inoculated into the vagina of mice during the pseudo estrus period for 7 days to construct a VVC model, followed by drug treatment for 7 days. Gram staining was used to observe the morphology of C. albicans in the vaginal secretions of mice; the amount of fungal load on the vaginal mucosa of mice was detected on agar plate; the pathological status of murine vaginal mucosa was observed by hematoxylin-eosin staining(HE); the integrity of mice vaginal mucosal epithelial barrier was observed by Masson's trichrome staining(MT), HE and periodic acid-schiff staining(PAS). Mucin-1 and mucin-4 protein expression levels of vaginal mucosal epithelial cells in mice were detected by immunohistochemistry; mucin-1 and mucin-4 protein expression levels on mucosal epithelial cells at 0 d, 3 d, and 7 d were determined by Western blot. The results showed that, in VVC model group, there were a large number of C. albicans hyphae and higher fungal load in vagina, within complete mucosal structure, cornified layer shed off, and the protein expression levels of mucin-1 and mucin-4 were significantly increased. After BAEB treatment, the hyphae in the vagina decreased; the fungal load decreased; the vaginal mucosal tissue damages were improved; the epithelial barrier was repaired, and mucin-1 and mucin-4 protein expression levels were down-regulated. The above results indicated that BAEB may play a role in the treatment of VVC by remodeling the integrity of the vaginal mucosal epithelial barrier.

[Transcriptome analysis of "Langmei" fruits and key enzyme genes structure and function prediction involved in citric acid biosynthesis].

Prunus mume "Langmei" is a relict tree species, which fruit has good medicinal value. To understand the biosynthesis pathway of citric acid, the Illumina HiSeq XTen high-throughput sequencing technology was used to get the transcriptome from "Langmei". A total of 38 936 unigenes were obtained by assembling the fruit transcripts, of which 28 311 unigenes were successfully annotated in public databases, 15 193 unigenes were mapped to 265 KEGG metabolic pathways, and 18 908 unigenes were classified into 59 GO functional subclasses, 103 unigenes encoding 15 key enzymes involved in citric acid synthesis pathway were identified and analyzed. The structural model of citrate synthetase in "Langmei" showed that it was a homodimer and the secondary structure of each monomer was mainly composed of alpha helixes. Moreover, the residues in the active site of the citrate synthetase were highly conserved. This study provides a valuable resource for identifying candidate genes involved in the citric acid biosynthesis pathway, and will promote the development and sustainable utilization of genetic resources of "Langmei".

Characterization of Volatile Compounds in Four Different Rhododendron Flowers by GC×GC-QTOFMS.

Volatile compounds in flowers of Rhododendron delavayi, R. agastum, R. annae, and R. irroratum were analyzed using comprehensive two-dimensional gas chromatography-mass spectrometry (GC×GC) coupled with high-resolution quadrupole time-of-flight mass spectrometry (QTOFMS). A significantly increased number of compounds was separated by GC×GC compared to conventional one-dimensional GC (1DGC), allowing more comprehensive understanding of the volatile composition of Rhododendron flowers. In total, 129 volatile compounds were detected and quantified. Among them, hexanal, limonene, benzeneacetaldehyde, 2-nonen-1-ol, phenylethyl alcohol, citronellal, isopulegol, 3,5-dimethoxytoluene, and pyridine are the main compounds with different content levels in all flower samples. 1,2,3-trimethoxy-5-methyl-benzene exhibits significantly higher content in R. irroratum compared to in the other three species, while isopulegol is only found in R. irroratum and R. agastum.

Current status and nurses' perceptions of the electronic tabular nursing records in Henan, China.

AIMS: To survey the types of Electronic Nursing Records used and to explore nurses' perceptions in the hospitals in Henan Province, China. BACKGROUND: There are few studies about status of electronic nursing documents from nurses' view. METHOD: A cross-sectional study of 3,586 nurses using a web-based questionnaire was conducted. RESULTS: Approximately 98% of the nurses were college graduates or had higher degrees, with 46% of the nurses managed more than nine beds per nurse each day. About 27% spent more than two hours daily writing records with a further 38% spending between 1 and 2 hr. However, only 52% realized professional nursing records should be archived and fewer than 80% knew the importance and significance of preserving fundamental nursing records. CONCLUSION: Although nurses' educational level in Henan is high, the younger age of them (i.e., less experience) and heavy workload may lead to inferior quality of ENR. Nurses' awareness of the importance and legal significance of documents needs improvement. IMPLICATION FOR NURSING MANAGEMENT: Our results may provide detailed evidence of the time consuming as well as nurses' knowledge of, abilities in, and opinions about record-keeping in developed countries and bring potential clinical implications for the nursing managers worldwide.

HPLC-MRM relative quantification analysis of fatty acids based on a novel derivatization strategy.

Fatty acids (FAs) are associated with a series of diseases including tumors, diabetes, and heart diseases. As potential biomarkers, FAs have attracted increasing attention from both biological researchers and the pharmaceutical industry. However, poor ionization efficiency, extreme diversity, strict dependence on internal standards and complicated multiple reaction monitoring (MRM) optimization protocols have challenged efforts to quantify FAs. In this work, a novel derivatization strategy based on 2,4-bis(diethylamino)-6-hydrazino-1,3,5-triazine was developed to enable quantification of FAs. The sensitivity of FA detection was significantly enhanced as a result of the derivatization procedure. FA quantities as low as 10 fg could be detected by high-performance liquid chromatography coupled with triple-quadrupole mass spectrometry. General MRM conditions were developed for any FA, which facilitated the quantification and extended the application of the method. The FA quantification strategy based on HPLC-MRM was carried out using deuterated derivatization reagents. "Heavy" derivatization reagents were used as internal standards (ISs) to minimize matrix effects. Prior to statistical analysis, amounts of each FA species were normalized by their corresponding IS, which guaranteed the accuracy and reliability of the method. FA changes in plasma induced by ageing were studied using this strategy. Several FA species were identified as potential ageing biomarkers. The sensitivity, accuracy, reliability, and full coverage of the method ensure that this strategy has strong potential for both biomarker discovery and lipidomic research.

Revealing the oncogenic role of elevated GNL3L expression in esophageal squamous cell carcinoma: insights into the STAT3 pathway.

Background: Esophageal squamous cell carcinoma (ESCC) patients carries a poor prognosis, with limited effective therapeutic targets. This study aimed to clarify the clinical significance of guanine nucleotide-binding protein like 3-like (GNL3L) protein expression in ESCC and its role in malignant progression. Methods: GNL3L expression and associated cancer-promoting pathways in ESCC were interrogated via bioinformatics analysis through use of The Cancer Genome Atlas (TCGA) database. Subsequent verification of GNL3L protein expression in ESCC, coupled with clinical data, was conducted through immunohistochemistry and followed by a comprehensive prognostic analysis. We further investigated potential signaling pathways facilitating ESCC progression, employing a combination of bioinformatics analysis and immunohistochemical (IHC) experiments. Results: Bioinformatics analysis unveiled a significant elevation in GNL3L expression, particularly in gastrointestinal tumors and ESCC. Immunohistochemistry confirmed elevated GNL3L expression in ESCC tissues. Regression analysis established a correlation between elevated GNL3L expression and advanced tumor node metastasis (TNM) stage, with high expression associated with poor prognosis in patients with ESCC. Our integrated approach of bioinformatics and IHC analysis indicated a potential role of the signal transducers and activators of transcription 3 (STAT3) signaling pathway in ESCC progression. Conclusions: High GNL3L expression significantly contributes to the malignant progression of ESCC. This study further elucidates the mechanisms driving ESCC progression and offers possible insights for more effective diagnosis and treatment strategies.

Effect of follicle-stimulating hormone and luteinizing hormone on apoptosis, autophagy, and the release and reception of some steroid hormones in yak granulosa cells through miR-23a/ASK1 axis.

Follicle-stimulating hormone (FSH), luteinizing hormone (LH), miR-23a, apoptosis signal-regulating kinase 1(ASK1)/c-Jun N-terminal kinase (JNK), autophagy and apoptosis play crucial roles in follicular development. However, their role in yak granulosa cells (GCs) remains unknown. Therefore, we examined the effect of miR-23a, ASK1, FSH, and LH on apoptosis, autophagy, and the release and reception of some steroid hormones in these cells. Our results showed that miR-23a overexpression significantly increased the abundance of Beclin1, the LC3II/I ratio, and the number of Ad-mRFP-GFP-LC3-labeled autophagosomes, and decreased p62 abundance. Additionally, Bax abundance and the number of terminal deoxynucleotidyl transferase deoxynucleotide triphosphate nick end labeling-positive cells were reduced, while Bcl2 expression was increased. Overexpression of miR-23a also significantly increased the abundance of estradiol receptor α (ER-α) and ß (ER-ß) and the concentrations of estradiol (E2), progesterone (P4) in yak GCs. Here, treating yak GCs with miR-23a decreased ASK1 expression, which regulates ASK1/JNK-mediated apoptosis, autophagy, E2 and P4 levels, and ER-α/ß abundance. In contrast, treatment of yak GCs with FSH (10 µg/mL) and LH (100 µg/mL) increased miR-23a abundance, regulating the subsequent effect on ASK1/JNK-mediated apoptosis, autophagy, ER-α/ß abundance, and E2 and P4 concentrations. In conclusion, miR-23a enhances autophagy in yak GCs, attenuates apoptosis, and increases ER-α/ß abundance and E2 and P4 concentrations by downregulating ASK1. Additionally, FSH and LH can regulate these effects of miR-23a by altering its expression. These results provide important insights that can inform the development of strategies to reduce abnormal follicular atresia and improve the reproductive rate of yaks.

MTDH-stabilized DDX17 promotes tumor initiation and progression through interacting with YB1 to induce EGFR transcription in Hepatocellular Carcinoma.

Metadherin (MTDH) is a well-established oncogene in various cancers including Hepatocellular Carcinoma (HCC). However, the precise mechanism through which MTDH promotes cancer-related signaling pathways in HCC remains unknown. In this study, we identified DDX17 as a novel binding partner of MTDH. Furthermore, MTDH increased the protein level of DDX17 by inhibiting its ubiquitination. We confirmed that DDX17 was a novel oncogene, with dramatically upregulated expression in HCC tissues. The increased expression of DDX17 was closely associated with vascular invasion, TNM stage, BCLC stage, and poor prognosis. In vitro and in vivo tests demonstrated that DDX17, a downstream target of MTDH, played a crucial role in tumor initiation and progression. Mechanistically, DDX17 acted as a transcriptional regulator that interacted with Y-box binding protein 1 (YB1) in the nucleus, which in turn drove the binding of YB1 to its target epidermal growth factor receptor (EGFR) gene promoter to increase its transcription. This in turn increased expression of EGFR and the activation of the downstream MEK/pERK signaling pathway. Our results identify DDX17, stabilized by MTDH, as a powerful oncogene in HCC and suggest that the DDX17/YB1/EGFR axis contributes to tumorigenesis and metastasis of HCC.

Lymphoid hyperplasia detected as a single mass in the gallbladder: report of a case.

We herein report a case of lymphoid hyperplasia of the gallbladder that showed unique images on computed tomography and ultrasonography. A 42-year-old female was referred to our hospital for evaluation and treatment of a gallbladder tumor. Ultrasonography and computed tomography showed a mass in the wall of the gallbladder neck, without typical findings of benign or malignant tumors. The serum levels of tumor markers, such as carcinoembryonic antigen, carbohydrate antigen 19-9, alpha-fetoprotein, and cytokeratin 19 fragment, were all within normal limits. Laparoscopic cholecystectomy was therefore performed. There were no stones in the gallbladder. Macroscopically, the submural tumor had a clear border without a capsule and a cystic portion. Its cut surface was grayish white. Microscopically, many lymph follicles with germinal centers were recognized in the subserosal layer. The lymphocytes were morphologically normal. We diagnosed lymphoid hyperplasia with chronic cholecystitis. Lymphoid hyperplasia of the gallbladder is extremely rare.

Retard or exacerbate: Role of long non-coding RNA growth arrest-specific 5 in the fibrosis.

Fibrosis is the endpoint of pathological remodeling involving different expressions of non-coding RNA(ncRNA) including long non-coding RNA growth arrest-specific 5 (lncRNA Gas5). Up to now, many studies have demonstrated that lncRNA Gas5 may play a vital regulatory role in the occurrence and development of organ fibrosis including liver, renal and cardiac fibrosis et al. Furthermore, Gas5 may also serve as a biomarker in diagnostic settings for fibrosis diseases. Structurally, IncRNA Gas5 impacts fibrosis via its distinct structural modules. In response to various external stresses, distinct functional complexes on different parts of Gas5 sequence influence cell proliferation and survival, thus affecting the inflammatory process and deposition of extracellular matrix(ECM) in organ fibrosis. However, there is no consensus on the role of Gas5 in fibrosis and its changed expression under various circumstances. In this review, we present an overview of what is known about the effect of Gas5 in organ fibrosis so far and for the first time explain its mechanism in the progression of fibrosis based on its unique structure.

Causes of peritoneal injury during laparoscopic totally extraperitoneal inguinal hernia repair and methods of repair.

INTRODUCTION: Peritoneal injury during laparoscopic totally extraperitoneal (TEP) inguinal hernia repair is an intraoperative complication that affects accomplishment. We retrospectively examined the causes of peritoneal injury and methods of TEP repair. METHODS: This study examined 58 patients with inguinal hernia (43 unilateral, 15 bilateral) who had undergone TEP repair; all procedures were performed by the same surgeon. The incidence of peritoneal injury, clinical characteristics that could have influenced peritoneal injury, and management of the injury were analyzed. RESULTS: Peritoneal injury was noted in 16 inguinal hernias (21.9%, 16 /73). Injury occurred more frequently in right-sided hernias than in left-sided hernias (31.6% vs 11.4%, P = .049). No other factors were related to injury. Peritoneal injury occurred due to anatomical misrecognition in five hernias (31.3%, 5/16) and unintentional dissection in six hernias (37.5%, 6/16). All injuries due to unintentional dissection occurred in right-sided hernias. The procedures used for peritoneal injury repair were endoscopic suturing for 4 hernias, pre-tied loop ligation for 1 hernia, and ligation clips in 11 hernias. Additional techniques were required in three hernias repaired by endoscopic suturing (75% 3/4). After introduction of the ligation clips, endoscopic suturing was discontinued, and no additional techniques were needed. CONCLUSION: Peritoneal injury more frequently occurred in right-sided inguinal hernia than in left-sided inguinal hernia during TEP repair. The common reasons for peritoneal injury were anatomical misrecognition and unintentional dissection. Repair using ligation clips is the best option for peritoneal injuries that occur during TEP repair.
