AIM: To compare the effects of different nucleus chopping methods on the central corneal thickness, corneal endothelial cell(CEC)count and tear inflammatory indicators in patients with hard nucleus cataract.METHODS: Retrospective study. Totally 89 patients(89 eyes)with hard nucleus cataract who treated in our hospital were included from January 2020 to December 2022. According to different intraoperative nucleus chopping methods, the patients were divided into reverse prechop group(46 eyes)and phaco-chop group(43 eyes). The total effective rate of surgery and visual acuity recovery were compared between the two groups. Corneal related indicators(central corneal thickness, CEC count, CEC area), tear inflammatory indicators and tear film function [tear film break-up time(BUT), Chinese Dry Eye Questionnaire(CDEQ), Schirmer Ⅰ test(SⅠt)] were observed before and after surgery in both groups, and the degree of corneal edema was evaluated.RESULTS: The effective phaco time, phaco energy and cumulative complex energy parameters in the phaco-chop group were longer or higher than those in the reverse prechop group(P<0.05). The macular retinal thickness in the reverse prechop group at 7 d and 1 mo after surgery was thinner than that in the phaco-chop group, the central corneal thickness at 3 and 7 d after surgery was also thinner than that in the phaco-chop group, the CEC count at 3 mo after surgery was more than that in the phaco-chop group, the CEC loss rate was lower than that in the phaco-chop group, and the CEC area at 3 mo after surgery was smaller than that in the phaco-chop group(P<0.05). The levels of tear TNF-α and IL-6 at 7 d and 1 mo after surgery in the reverse prechop group were lower than those in the phaco-chop group(P<0.05). The BUT at 1 and 3 mo after surgery was longer in the reverse prechop group than that in the phaco-chop group(P<0.05). The CDEQ score in the reverse prechop group was lower than that in the phaco-chop group at 1 and 3 mo after surgery(P<0.05). The SⅠt at 1 and 3 mo after surgery was higher in the reverse prechop group compared with that in the phaco-chop group(P<0.05). The degree of corneal edema at 1 d after surgery was milder in the reverse prechop group than that in the phaco-chop group(P<0.05). CONCLUSION: Compared with phaco-chop, the application of reverse-chopper prechop combined with phacoemulsification can better reduce the ultrasonic energy in the treatment of hard nuclear cataract, and it is more conducive to reducing the postoperative inflammatory degree, improving the tear film function and relieving the corneal edema degree.

Osteoarthritis (OA) and stroke are common clinical diseases that reduce patients' quality of life and place a burden on families and society. Ruyi Zhenbaowan, a classic prescription in Tibetan medicine, have the functions of clearing heat, awakening the brain and opening orifices, relaxing tendons and promoting meridian circulation, and eliminating yellow water. Clinically, they are used to treat osteoarthritis, post-stroke sequelae, neuropathic pain, and other related conditions. Modern pharmacological studies have demonstrated their anti-inflammatory, analgesic, and nerve-repairing effects. However, current research remains insufficient regarding the appropriate indications, timing, and efficacy of this medicine in treating relevant diseases. To enhance clinicians' understanding of this medicine and promote its standardized and rational clinical use, a panel of national experts, including clinical specialists, Tibetan medicine practitioners, pharmacologists, and methodologists, formulated this consensus based on clinical experience and evidence-based practice. The Cochrane systematic review framework, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, and the nominal group method were employed to generate seven graded recommendations and 19 consensus-based suggestions. These recommendations clearly define the key points in the clinical application of Ruyi Zhenbaowan, including therapeutic indications, dosage and administration, treatment duration, and medication safety. The consensus specifically addresses the clinical efficacy, appropriate timing of administration, dosage strategies, treatment cycles, and combination medication strategies for treating osteoarthritis and stroke and provides an overview of safety considerations. The aim is to provide standardized guidance for hospitals and healthcare institutions nationwide to ensure the rational application of Ruyi Zhenbaowan in the treatment of osteoarthritis and stroke, reduce medication-related risks, and further leverage its clinical advantages. This consensus has been approved and issued by the China Association of Chinese Medicine, with the standard number GS/CACM 369-2024.

ObjectiveMolecular docking and animal experiments were employed to explore the protective effect and mechanism of Da Chengqitang (DCQD) on intestinal barrier in septic mice. MethodText mining method was used to screen the active ingredients in DCQD. AutoDock Tools and Discovery Studio were used to study the interactions of active components with the core target proteins [claudin-1, tumor necrosis factor (TNF)-α, interleukin (IL)-6, endogenous antimicrobial peptide mCRAMP, Toll-like receptor 4 (TLR4), and myeloid differentiation primary response gene 88 (MyD88)] in sepsis. Fifty C57BL/6 mice were randomized into sham, model, low- and high-dose (4 g∙kg-1 and 8 g∙kg-1) DCQD, and ulinastatin groups (n=10). Before, during, and after the day of modeling surgery, each group was administrated with corresponding drugs. The mice in other groups except the model group were subjected to modeling by cecal ligation and puncture. Enzyme-linked immunosorbent assay (ELISA) was used measure the serum level of D-lactic acid to assess intestinal mucosa permeability. Hematoxylin-eosin staining was employed to observe the histopathological changes in the ileum and assess the intestinal mucosal damage and inflammatory infiltration. Western blotting was employed to determine the expression levels of tight junction proteins claudin-1 and occludin in the ileal tissue, which were indicative of the bowel barrier function. The TNF-α and IL-6 levels were measured by ELISA to assess the intestinal inflammation. The expression of mCRAMP in the ileal tissue was observed by immunohistochemistry. The mRNA levels of mCRAMP, TLR4, and MyD88 in mouse ileal tissue were determined by Real-time polymerase chain reaction, on the basis of which the mechanism of DCQD in protecting the intestinal barrier of septic mice was explored. ResultMolecular docking results showed that most of the 10 active ingredients of DCQD that were screened out by text mining could bind to sepsis targets by van der Waals force, hydrogen bonding, and other conjugated systems. The results of animal experiments showed that compared with the model group, low- or high-dose DCQD lowered the D-lactic acid level in the serum (P<0.01), alleviated damage to the ileal tissue and mucosal edema, protected the small intestine villus integrity, reduced inflammatory cell infiltration, promoted the expression of claudin-1 (P<0.01), lowered the IL-6 level (P<0.01), up-regulated the mRNA and protein levels of mCRAMP (P<0.01), and down-regulated the mRNA and protein levels of TLR4 and MyD88 (P<0.01) in the ileal tissue. In addition, high-dose DCQD lowered the TNF-α level and promoted the expression of occludin in the ileum tissue (P<0.01), and low-dose DCQD up-regulated the protein level of occludin in the ileum tissue (P<0.05). ConclusionDCQD has a protective effect on intestinal barrier in septic mice. It can reduce intestinal inflammation, repair intestinal mucosal damage, improve the tight junction protein level, and reduce intestinal mucosal permeability by up-regulating the mRNA and protein levels of mCRAMP and the down-regulating the expression of genes in the TLR4/MyD88 pathway.

Objective:To analyze changes in energy metabolism and oxylipin metabolism in macrophages after stimulation by Mycobacterium marinum ( M. marinum) using targeted metabolomics, and to provide insights into the mechanisms underlying the immune defense by macrophages against M. marinum infections. Methods:Mouse bone marrow-derived macrophages were obtained from the bilateral femurs of mice, and cultured cells were divided into two groups: the active M. marinum group and the inactivated M. marinum group. Bacterial suspensions were prepared using M. marinum clinical isolates; the active M. marinum group was treated with live M. marinum suspensions for 12 hours, while the inactivated M. marinum group with inactivated M. marinum suspensions for 12 hours. Cell morphology was observed through microscopy, and cell length was measured. Cell lysates collected from both groups were subjected to liquid chromatography-tandem mass spectrometry analysis to detect energy and oxylipin metabolites. A t-test was utilized to compare the lengths of macrophages between the two groups, while principal component analysis and orthogonal partial least squares-discriminant analysis were conducted to identify differential metabolites. Results:Under the microscope, macrophages in the active M. marinum group formed more granuloma-like cell aggregates compared with those in the inactivated M. marinum group; the macrophages were significantly thinner and longer in the inactivated M. marinum group (439.52 ± 91.67 μm) than in the active M. marinum group (289.96 ± 70.11 μm, P < 0.001). Principal component analysis and orthogonal partial least squares-discriminant analysis of energy metabolism and oxylipin metabolism in macrophages demonstrated good separation between the two groups. As for the energy metabolism, a total of 12 differential metabolites were identified, with the amino acid metabolism showing the most significant changes. Specifically, there was a significant increase in the content of L-citrulline, while the content of L-leucine and serine decreased. As for the oxylipin metabolism, 20 differential metabolites were identified, with the arachidonic acid metabolism showing the most significant changes. Conclusions:Macrophages stimulated by live M. marinum exhibited altered amino acid metabolism and arachidonic acid metabolism compared with those stimulated by inactivated M. marinum, characterized by an increase in L-citrulline content, a decrease in L-leucine and serine levels, and alterations in arachidonic acid content.

Objective To explore the nutritional efficacy of compound protein powder formulations from different sources. Methods Three groups of compound protein powder formulations were obtained through scientific blending using soy protein, whey protein and yeast protein as raw materials. The effects of the compound protein powders on nitrogen metabolism, serum biochemical indicators, and pathological changes of liver tissue and epididymal fat in rats were evaluated. Results Compared with the control (casein), the net protein utilization, biological evaluation, and protein efficacy ratio of the compound protein powders in rats were significantly improved, and the changes in these indicators in the formula with the highest whey protein content were most significant among all three formulas. The compound protein powders effectively increased the levels of albumin and globulin, while decreased the content of total cholesterol, indicating beneficial effects on improving immunity and controlling lipid metabolism, with the formula group 2 being the most effective among all three groups. The pathological examination showed that the three groups of protein powder did not have adverse effects on liver tissue and epididymal fat. Conclusion The present study demonstrates that the compound protein powder formulation has nutritional value, which suggests a potential of the application of the compound protein powder formulation in the elderly, and people with special nutritional needs, such as sports people.

While Mek1/2 and Gsk3β inhibition ("2i") supports the maintenance of murine embryonic stem cells (ESCs) in a homogenous naïve state, prolonged culture in 2i results in aneuploidy and DNA hypomethylation that impairs developmental potential. Additionally, 2i fails to support derivation and culture of fully potent female ESCs. Here we find that mouse ESCs cultured in 2i/LIF supplemented with lipid-rich albumin (AlbuMAX) undergo pluripotency transition yet maintain genomic stability and full potency over long-term culture. Mechanistically, lipids in AlbuMAX impact intracellular metabolism including nucleotide biosynthesis, lipid biogenesis, and TCA cycle intermediates, with enhanced expression of DNMT3s that prevent DNA hypomethylation. Lipids induce a formative-like pluripotent state through direct stimulation of Erk2 phosphorylation, which also alleviates X chromosome loss in female ESCs. Importantly, both male and female "all-ESC" mice can be generated from de novo derived ESCs using AlbuMAX-based media. Our findings underscore the importance of lipids to pluripotency and link nutrient cues to genome integrity in early development.
