Causative Microorganisms Isolated from Patients with Intra-Abdominal Infections and Their Drug Resistance Profiles: An 11-Year (2011-2021) Single-Center Retrospective Study / 生物医学与环境科学（英文）

OBJECTIVE@#To investigate the distribution and antimicrobial susceptibility of causative microorganisms recovered from patients with intra-abdominal infections (IAIs).@*METHODS@#A total of 2,926 bacterial and fungal strains were identified in samples collected from 1,679 patients with IAIs at the Peking Union Medical College Hospital between 2011 and 2021. Pathogenic bacteria and fungi were identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Antimicrobial susceptibility testing (AST) was performed using the VITEK 2 compact system and the Kirby-Bauer method. AST results were interpreted based on the M100-Ed31 clinical breakpoints of the Clinical and Laboratory Standards Institute.@*RESULTS@#Of the 2,926 strains identified, 49.2%, 40.8%, and 9.5% were gram-negative bacteria, gram-positive bacteria, and fungi, respectively. Escherichia coli was the most prevalent pathogen in intensive care unit (ICU) and non-ICU patients; however, a significant decrease was observed in the isolation of E. coli between 2011 and 2021. Specifically, significant decreases were observed between 2011 and 2021 in the levels of extended-spectrum β-lactamase (ESBL)-producing E. coli (from 76.9% to 14.3%) and Klebsiella pneumoniae (from 45.8% to 4.8%). Polymicrobial infections, particularly those involving co-infection with gram-positive and gram-negative bacteria, were commonly observed in IAI patients. Moreover, Candida albicans was more commonly isolated from hospital-associated IAI samples, while Staphylococcus epidermidis had a higher ratio in community-associated IAIs. Additionally, AST results revealed that most antimicrobial agents performed better in non-ESBL-producers than in ESBL-producers, while the overall resistance rates (56.9%-76.8%) of Acinetobacter baumanmii were higher against all antimicrobial agents than those of other common gram-negative bacteria. Indeed, Enterococcus faecium, Enterococcus faecalis, S. epidermidis, and S. aureus were consistently found to be susceptible to vancomycin, teicoplanin, and linezolid. Similarly, C. albicans exhibited high susceptibility to all the tested antifungal drugs.@*CONCLUSION@#The distribution and antimicrobial susceptibility of the causative microorganisms from patients with IAIs were altered between 2011 and 2021. This finding is valuable for the implementation of evidence-based antimicrobial therapy and provides guidance for the control of hospital infections.

Xuebijing injection, a Chinese patent medicine, against severe pneumonia: Current research progress and future perspectives / 中西医结合学报

Severe pneumonia is one of the most common infectious diseases and the leading cause of sepsis and septic shock. Preventing infection, balancing the patient's immune status, and anti-coagulation therapy are all important elements in the treatment of severe pneumonia. As multi-target agents, Xuebijing injection (XBJ) has shown unique advantages in targeting complex conditions and saving the lives of patients with severe pneumonia. This review outlines progress in the understanding of XBJ's anti-inflammatory, endotoxin antagonism, and anticoagulation effects. From the hundreds of publications released over the past few years, the key results from representative clinical studies of XBJ in the treatment of severe pneumonia were selected and summarized. XBJ was observed to effectively suppress the release of pro-inflammatory cytokines, counter the effects of endotoxin, and assert an anticoagulation effect in most clinical trials, which are consistent with experimental studies. Collectively, this evidence suggests that XBJ could play an important and expanding role in clinical medicine, especially for sepsis, septic shock and severe pneumonia.

Evaluation of porcine urine-derived cells as nuclei donor for somatic cell nuclear transfer

Background@#Somatic cell nuclear transfer (SCNT) is used widely in cloning, stem cell research, and regenerative medicine. The type of donor cells is a key factor affecting the SCNT efficiency. @*Objectives@#This study examined whether urine-derived somatic cells could be used as donors for SCNT in pigs. @*Methods@#The viability of cells isolated from urine was assessed using trypan blue and propidium iodide staining. The H3K9me3/H3K27me3 level of the cells was analyzed by immunofluorescence. The in vitro developmental ability of SCNT embryos was evaluated by the blastocyst rate and the expression levels of the core pluripotency factor. Blastocyst cell apoptosis was examined using a terminal deoxynucleotidyl transferase dUTP nick end-labeling assay. The in vivo developmental ability of SCNT embryos was evaluated after embryo transfer. @*Results@#Most sow urine-derived cells were viable and could be cultured and propagated easily. On the other hand, most of the somatic cells isolated from the boar urine exhibited poor cellular activity. The in vitro development efficiency between the embryos produced by SCNT using porcine embryonic fibroblasts (PEFs) and urine-derived cells were similar.Moreover, The H3K9me3 in SCNT embryos produced from sow urine-derived cells and PEFs at the four-cell stage showed similar intensity. The levels of Oct4, Nanog, and Sox2 expression in blastocysts were similar in the two groups. Furthermore, there is a similar apoptotic level of cloned embryos produced by the two types of cells. Finally, the full-term development ability of the cloned embryos was evaluated, and the cloned fetuses from the urine-derived cells showed absorption. @*Conclusions@#Sow urine-derived cells could be used to produce SCNT embryos.

Transformation pathways in methanol of echinacoside, a principal effective ingredient of Cistanches Herba / 中国中药杂志

Echinacoside (ECH) is one of the active ingredients in Cistanche Herba and the principal effective component of Memoregain© as well. Moreover, a new agent namely Naoqing Zhiming tablet, derived from ECH has been licensed for clinical trials. However, the knowledge regarding the stability of is limited, till now, initiating a significant barrier for its further development along with the clinical trials. Herein, we aim to in depth characterize the transformation pattern of ECH in methanol. When ECH was stored in methanol, two primary products (P1 and P2) could be observed in HPLC chromatogram. A home-made automated fraction collector was configured via employing two 2-phase/6-port electronic valves to prepare P1 and P2. Following ¹H-NMR and LC-MS/MS assays, P1 and P2 were unambiguously identified as acteoside and cistanoside A, respectively. Moreover, the existences of cis-ECH, cis-acteoside, and cis-cistanoside A were claimed after careful analysis of the ¹H-NMR spectra of ECH, P1 and P2. Above all, the primary transformation pathways of ECH in methanol included methylation as well as hydrolysis, and mild transformation could also be initiated by cis/trans- configuration transferring for the caffeoyl group. The findings obtained in current study are envisioned to provide useful insight for the further development of ECH and the impurity detection of Naoqing Zhiming tablet. Moreover, the automated fraction collector configured in current study is able to serve as a versatile tool for the collection of signals-of-interest within phytochemical evaluations and impurity isolation.

Combined use of 1,25-dihydroxyvitamin D3 and dexamethasone promotes osteogenic differentiation of synovial fluid mesenchymal stem cells from human temporomandibular joint / 中国组织工程研究

BACKGROUND:Synovial fluid mesenchymal stem cells can be amplified rapidly in vitro and collected by a minimally invasive method. Recent studies have suggested that synovial fluid mesenchymal stem cells have become an important kind of seed cells for bone tissue engineering. Osteogenic differentiation is required to be optimized prior to the application of synovial fluid mesenchymal stem cells in the bone regeneration. OBJECTIVE: To describe a protocol to generate osteoblast-lineage cells from human synovial fluid mesenchymal stem cells of the temporomandibular joint using a cocktail that includes glutamax, dexamethasone, β-glycerophosphate, vitamin C, 1,25-dihydroxyvitamin D3, and to investigate the effect of 1,25-dihydroxyvitamin D3 and dexamethasone on the osteogenic capacity of synovial fluid mesenchymal stem cells. METHODS:Synovial fluid mesenchymal stem cells from the human temporomandibular joint were expanded in vitro and cultured in different osteogenic induction media. The mineralization capacity of osteogenic differentiation was evaluated by alizarin red and Von kossa staining. And the osteogenic markers, including ALP, RUNX2 and OCN, were assessed by reverse transcription-PCR. RESULTS AND CONCLUSION: The mineralization formation increased greatly in the medium with 100 nmol/L dexamethasone and 10 nmol/L 1,25-dihydroxyvitamin D3. The expression of ALP, RUNX2 and OCN was enhanced distinctly in the 1,25-dihydroxyvitamin D3-induced differentiated cells. These findings reveal that appropriate concentration of 1,25-dihydroxyvitamin D3 and dexamethasone can be ideal ingredients to induce the osteogenic differentiation of human synovial fluid mesenchymal stem cells of the temporomandibular joint. Thus, this effective condition can be used to induce the osteogenic differentiation of synovial fluid mesenchymal stem cells for the bone regeneration in the temporomandibular joint.

Chemical characterization for flowers and lignified stems of Cistanche deserticola / 中国中药杂志

As a holoparasitic plant, Cistanche deserticola is one of the two original sources of Cistanches Herba that is one of the most famous tonic medicines, in Chinese Pharmacopoeia. The succulent stems are used for medicinal usage, whereas those lignified stems as well as flowers of less pharmacological importance are usually deserted, suggesting extensive resource waste. Herein, chemical characterization of the flowers along with lignified stems was conducted using HPLC-IT-TOF-MS aiming to explore the medicinal valu of those non-medicinal parts. Following ultrasonication-assisted extraction with 50% aqueous methanol, either flower or lignified stem extract was subjected onto LC-IT-TOF-MS equipped with a Capcell core ADME column to acquire both MS¹ and MSº spectra, and gradient elution was carried out with combinatory 0.1% aqueous formic acid and acetonitrile. Both positive and negative ionization polarities were deployed, resulting in the observation of 62 components, in total. Thirty-nine signals were structurally annotated, including phenylethanoid glycosides, iridoids, lignans and saccharides according to matching with authentic components and literature information, as well as applying the proposed mass fragmentation rules. A total of 62 ones were putatively identified. Above all, lignified stems and flowers should not the qualified substitutes for the succulent stems attributing to the significant differences between the medicinal portion and those parts with less medicinal values.

Chemome comparison between cultivated and wild Cistanche tubulosa using ¹H-NMR spectroscopy / 中国中药杂志

As a famous tonic medicine, Cistanche tubulosa has been honored as "ginseng of the deserts" for centuries. Aiming to address the resource shortage as well as the wild resource protection towards this herbal medicine, wide cultivation has been achieved in the southern Xinjiang. Herein, in-depth chemome comparison was conducted between cultivated and wild plants using ¹H-NMR spectroscopy that is capable of comprehensively providing qualitative and quantitative information of given complicated matrices. Multivariate statistical analysis was employed to process the dataset as well as to consolidate that the cultivated plants are comparable to those wild ones in term of chemome. ¹H-NMR spectra of both wild and cultivated plants were acquired in parallel after extraction. Following direct overlaying, great similarity occurred between these two groups. A total of 28 compounds were tentatively identified by referring to authentic compounds together with those available databases, such as HMDB and BMRB. Following principal component analysis, none significant difference was observed between wild and cultivated groups. Above all, from the viewpoint of chemical profile, the cultivated plants were almost equal to the wild plants; therefore, the cultivated plants are able to take the load of wild plants in clinical usage. Moreover, ¹H-NMR spectroscopy is a promising tool for chemical profiling traditional Chinese medicines because of the potential towards simultaneously exhibiting both quantitative and qualitative information for complicated matrices.

Plasminogen Activator Inhibitor 1 as a Poor Prognostic Indicator in Resectable Pancreatic Ductal Adenocarcinoma / 中华医学杂志(英文版)

Background@#Plasminogen activator inhibitor 1 (PAI-1) was previously established to impact several phenotypes in many kinds of cancer, including pancreatic cancer. However, its prognostic significance in pancreatic ductal adenocarcinoma (PDAC) needs support of further evidence. This study was designed to address the issue.@*Methods@#PAI-1 expression was detected by tissue microarray-based immunohistochemical staining in formalin-fixed paraffin-embedded specimens from 93 PDAC patients with surgical resection from September 2004 to December 2008. Its relationships with clinicopathologic variables and tumor-specific survival (TSS) were further evaluated using Chi-square, Kaplan-Meier, log-rank, as well as Cox regression analyses.@*Results@#Expression of PAI-1 was much higher in tumor than that in nontumor tissues, based on comparison of all samples and 74 matched ones (95 [47.5, 180] vs. 80 [45, 95], Z = -2.439, P = 0.015 and 100 [46.9, 182.5] vs. 80 [45, 95], Z = -2.594, P = 0.009, respectively). In addition, tumoral PAI-1 expression was positively associated with N stage (22/35 for N1 vs. 21/51 for N0, χ = 3.903, P = 0.048). Univariate analyses showed that TSS of patients with high PAI-1 tumors was significantly poorer than that of those with low PAI-1 tumors (log rank value = 19.00, P < 0.0001). In multivariate Cox regression test, PAI-1 expression was identified as an independent predictor for long-term prognosis of resectable PDAC (hazard ratio = 2.559, 95% confidence interval = 1.499-4.367, P = 0.001).@*Conclusion@#These results suggest that expression of PAI-1 is upregulated in PDAC and might serve as a poor prognostic indicator.
