Dendrite-Free Dual-Phase Li-Ba Alloy Anode Enabled by Ordered Array of Built-in Mixed Conducting Microchannels.

The development and application of lithium (Li) anode is hindered by volumetric variation, dendritic Li growth, and parasitic reactions. Herein, a dual-phase Li-barium (Ba) alloy with self-assembled microchannels array is synthesized through a one-step thermal fusion method to investigate the inhibition effect of lithiophilic composite porous array on Li dendrites. The Li-rich Li-Ba alloy (BaLi24) as composite Li electrode exhibits an ordered porous structure of BaLi4 intermetallic compound after delithiation, which acts as a built-in 3D current collector during Li plating/striping process. Furthermore, the lithiophilic BaLi4 alloy scaffold is a mixed conductor, featuring with Li+ ions diffusion capability, which can efficiently transport the reduced Li to the interior of the electrode structure. This unique top-down growth mode can effectively prohibit Li dendrites growth and improve the space utilization of 3D electrode structure. The spin-polarized density functional theory (DFT) calculations suggest that the absorption capability of BaLi4 benefits the deposition of Li metal. As a result, the cell performance with the dual-phase Li-Ba alloy anode is significantly improved.

Synthesis of narrow-spectrum anti-mycobacterial molecules without effect on the diversity of gut microbiota in mice based on the structure of rifampicin.

Rifampicin (RIF) is a broad-spectrum antimicrobial agent that is also a first-line drug for treating tuberculosis (TB). Based on the naphthyl ring structure of RIF this study synthesized 16 narrow-spectrum antimicrobial molecules that were specifically anti-Mycobacterium tuberculosis (Mtb). The most potent candidate was 2-((6-hydroxynaphthalen-2-yl) methylene) hydrazine-1-carbothioamide (compound 3c) with minimum inhibitory concentration (MIC) of 1 µg/mL against Mtb. Synergistic anti-Mtb test indicated that none of the combinations of 3c with the major anti-TB drugs are antagonistic. Consistent with RIF, compound 3c induced large amounts of reactive oxygen radicals (ROS) in the cells of Mtb. The killing kinetics of compound 3c and RIF are very similar. Furthermore, molecular docking showed that compound 3c was able to access the RIF binding pocket of the ß subunit of Mtb RNA polymerase (RNAP). Experiments in mice showed that compound 3c increased the variety of intestinal flora in mice, while RIF significantly decreased the diversity of intestinal flora in mice. In addition, compound 3c is non-toxic to animal cells with a selection index (SI) much more than 10. The evidence from this study suggests that the further development of 3c could contribute to the development of novel drug for TB treatment.

Reverse Separation of Carbon Dioxide and Acetylene in Two Isostructural Copper Pyridine-Carboxylate Frameworks.

Separating acetylene from carbon dioxide is important but highly challenging due to their similar molecular shapes and physical properties. Adsorptive separation of carbon dioxide from acetylene can directly produce pure acetylene but is hardly realized because of relatively polarizable acetylene binds more strongly. Here, we reverse the CO2 and C2H2 separation by adjusting the pore structures in two isoreticular ultramicroporous metal-organic frameworks (MOFs). Under ambient conditions, copper isonicotinate (Cu(ina)2), with relatively large pore channels shows C2H2-selective adsorption with a C2H2/CO2 selectivity of 3.4, whereas its smaller-pore analogue, copper quinoline-5-carboxylate (Cu(Qc)2) shows an inverse CO2/C2H2 selectivity of 5.6. Cu(Qc)2 shows compact pore space that well matches the optimal orientation of CO2 but is not compatible for C2H2. Neutron powder diffraction experiments confirmed that CO2 molecules adopt preferential orientation along the pore channels during adsorption binding, whereas C2H2 molecules bind in an opposite fashion with distorted configurations due to their opposite quadrupole moments. Dynamic breakthrough experiments have validated the separation performance of Cu(Qc)2 for CO2/C2H2 separation.

Pd/Co Catalyst with High Pd Atom Utilization Efficiency for Nitrobenzene Hydrogenation at Room Temperature: Experimental and DFT Studies.

Enhancing catalytic performance as well as reducing catalyst cost are the eternal pursuit for the catalysis community. Herein, a simple and effective palladium-doped cobalt (Pd/Co) catalyst with high Pd atom utilization efficiency was synthesized via galvanic replacement reaction for the selective hydrogenation of nitrobenzene with H2 at room temperature, delivering >99 % yield of aniline with up to 158 times higher catalytic activity than commercial palladium powder. Detailed characterizations and DFT calculations revealed that Co-Pd interaction leads to a decrease in electron density of Pd and the distance between Pd atoms that results in the enhanced catalytic performance. Further experiments indicated that the Pd/Co catalyst serves as a highly efficient, selective, and recyclable catalyst for a range of nitroarene substrates. This work might provide a green and sustainable methodology to design and synthesize highly active catalysts with high utilization efficiency of the noble metals in fundamental and applied research.

Mechanisms of the Higher Catalytic Activity of Polymer Forms over Complexes for Non-pyrolytic Mono-1,10-phenanthroline-Coordinated Cu2+ (Cu-N2 Type) in an Oxygen Reduction Reaction.

In this paper, we have thoroughly investigated the ORR mechanism of non-pyrolytic mono-1,10-phenanthroline-coordinated Cu2+ (Cu-N2 type) complexes and polymers by molecular dynamics and quantum mechanics calculation. In contrast to the complex-catalyzed ORR, which follows a direct four-electron pathway along intermediates of Cu(I)-Phen, the polymer-catalyzed ORR follows an indirect four-electron pathway by intermediates of Cu(II)-Phen. By analyzing the structure, spin population, electrostatic potential (ESP), and density of states, we confirmed that the higher ORR catalytic activity of the polymer is due to the conjugation effect of coplanar phenanthroline and Cu(II) in the planar reactants or at the base of the square-pyramidal intermediates. The conjugation effect allows the highest ESP to be located near the active center Cu(II), while the lower ESPs are distributed on the phenanthroline, which is very favorable for the reduction current. This will serve as a theoretical foundation for the development of new highly efficient ORR non-pyrolytic CuN2 polymer catalysts.

Synthesis, antimycobacterial evaluation, and molecular docking study of 1,2,4-triazole derivatives.

Fifteen 1,2,4-triazole derivatives were synthesised in this study and their MIC values against Mycobacterium tuberculosis (Mtb) ranged from 2 to 32 µg/mL. Furthermore, their antimycobacterial activity was positively correlated with the KatG enzyme docking score. Among the 15 compounds, compound 4 showed the strongest bactericidal activity with an MIC of 2 µg/mL. The selectivity index of compound 4 is more than 10, indicating that the compound has low toxicity to animal cells and has the potential to become a drug. Molecular docking indicates that compound 4 can bind firmly to the Mtb KatG active site. The experimental results showed that compound 4 inhibited Mtb KatG and caused the accumulation of ROS in Mtb cells. We speculate that compound 4 causes the accumulation of ROS by inhibiting KatG, and ROS produces oxidative destruction, leading to the death of Mtb. This study provides a new idea for the development of novel anti-Mtb drugs.

Glabridin, a bioactive component of licorice, ameliorates diabetic nephropathy by regulating ferroptosis and the VEGF/Akt/ERK pathways.

BACKGROUND: Glabridin (Glab) is a bioactive component of licorice that can ameliorate diabetes, but its role in diabetic nephropathy (DN) has seldom been reported. Herein, we explored the effect and underlying mechanism of Glab on DN. METHODS: The bioactive component-target network of licorice against DN was by a network pharmacology approach. The protective effect of Glab on the kidney was investigated by a high-fat diet with streptozotocin induced-diabetic rat model. High glucose-induced NRK-52E cells were used for in vitro studies. The effects of Glab on ferroptosis and VEGF/Akt/ERK pathways in DN were investigated in vivo and in vitro using qRT-PCR, WB, and IHC experiments. RESULTS: Bioinformatics analysis constructed a network comprising of 10 bioactive components of licorice and 40 targets for DN. 13 matching targets of Glab were mainly involved in the VEGF signaling pathway. Glab treatment ameliorated general states and reduced FBG, HOMA-ß, and HOMA-insulin index of diabetic rats. The renal pathological changes and the impaired renal function (the increased levels of Scr, BUN, UREA, KIM-1, NGAL, and TIMP-1) were also improved by Glab. Moreover, Glab repressed ferroptosis by increasing SOD and GSH activity, and GPX4, SLC7A11, and SLC3A2 expression, and decreasing MDA and iron concentrations, and TFR1 expression, in vivo and in vitro. Mechanically, Glab significantly suppressed VEGF, p-AKT, p-ERK1/2 expression in both diabetic rats and HG-induced NRK-52E cells. CONCLUSIONS: This study revealed protective effects of Glab on the kidney of diabetic rats, which might exert by suppressing ferroptosis and the VEGF/Akt/ERK pathway.

Highly efficient continuous-wave and passively Q-switched Yb:YLuGdCOB compact lasers.

Highly efficient operation of an Yb:YLuGdCOB compact laser was demonstrated, producing an output power of 14.30 W around 1054 nm, with an optical-to-optical efficiency of 70.0% and a slope efficiency of 81%. In dual-polarization oscillation in an emission range of 1080 - 1085 nm, 11.37 W of output power was generated with a slope efficiency of 76%. Efficient passively Q-switched operation was also realized by incorporating a 2D MoTe2 saturable absorber into the compact resonator, producing a maximum pulsed output power of 1.56 W at 1030 nm at a repetition rate of 481 kHz; while the largest attainable pulse energy, minimum pulse duration, and highest peak power were, respectively, 3.87 µJ, 26.2 ns, and 147.7 W. The pulse width proves to be the shortest, while the peak power is the highest ever reported for solid-state lasers passively Q-switched with 2D saturable absorbers.

A case of chlamydia psittaci caused severe pneumonia and meningitis diagnosed by metagenome next-generation sequencing and clinical analysis: a case report and literature review.

BACKGROUND: Psittacosis, which is also known as parrot fever, is Chlamydia psittaci (C. psittaci) caused infectious disease. The clinical manifestations vary from asymptomatic infection to severe atypical pneumonia or even fatal meningitis. Early recognition of psittacosis is difficult because of its nonspecific clinical manifestations. Culture and gene probe techniques for C. psittaci are not available for routine clinical use, which makes the diagnosis difficult too. Although psittacosis has increasingly been recognized and reported in recent years, cure of severe pneumonia complicated with meningitis, with etiologic diagnosis aided by the use of metagenomic next-generation sequencing (mNGS), is still uncommon. So, it is necessary to report and review such potentially fatal case. CASE PRESENTATION: This report describes a 54-year-old woman with C. psittaci caused severe atypical pneumonia and meningitis. She presented with symptoms of fever, dry cough and dyspnea, accompanied by prominent headache. Her condition deteriorated rapidly to respiratory failure and lethargy under the treatment of empirical antibacterial agents, and was treated with invasive mechanical ventilation soon. She denied contact with birds, poultry or horses, but unbiased mNGS of both the bronchoalveolar lavage fluid (BALF) and the cerebrospinal fluid (CSF) identified sequence reads corresponding to C. psittaci infection, and there was no sequence read corresponding to other probable pathogens. Combined use of targeted antimicrobial agents of tetracyclines, macrolides and fluoroquinolones was carried out, and the patient's condition improved and she was discharged home 28 days later. Her status returned close to premorbid condition on day 60 of follow-up. CONCLUSIONS: When clinicians come across a patient with atypical pneumonia accompanied by symptoms of meningitis, psittacosis should be taken into consideration. mNGS is a promising detection method in such condition and is recommended.

Quantitative relationship between the structures and properties of VOCs and SOA formation on the surfaces of acidic aerosol particles.

In this research, all the efforts, based on a series of molecular dynamics simulations on the interfacial process between VOC-contaminated air and acidic sulfate, were made to find how the structures and properties of VOCs are related to the formation of SOAs. The experimental fractional aerosol coefficients (FACs) were used to quantify the SOA formation and 14 VOC species were chosen based on the atmosphere inventory and the FAC magnitude. Finally, the quantitative relationship (QR) was found through the FAC as a function of the two variables the total valid interactions (Tg) and the diffusion coefficient (D), with R square 0.94. Meanwhile, the effect of water was explored and the QR was proved to be rational and reliable. The QR not only explained the SOA formation capacity of VOCs, but could also predict the SOA formation of new molecules.

Allostery-Mimicking Self-assembly of Helical Poly(phenylacetylene) Block Copolymers and the Chirality Transfer.

Allostery can regulate protein self-assembly which further affects biological activities, and achieving precise control over the chiral suprastructures during self-assembly remains challenging. Herein, to mimic the allosterical nature of proteins, the poly(phenylacetylene) block copolymers PPA-b-PsmNap with the dynamic helical backbone were synthesized to investigate their conformational-transition-induced self-assembly. As the helical conformation of the block PsmNap spontaneously transforms from cis-transiod to cis-cisoid, the decreasing solubility of PsmNap blocks in THF induced self-assembly of PPA-b-PsmNap. The self-assembly structures of copolymers can sequentially evolve from vesicles to nanobelts to helical strands during the process of conformation transformation. The screw sense of final helical strands was strictly correlated to the helicity of the block PsmNap. This is helpful to understand the mechanism of allostery-modulated self-assembly.

Preventive effect of ursolic acid derivative on particulate matter 2.5-induced chronic obstructive pulmonary disease involves suppression of lung inflammation.

Respiratory diseases like chronic obstructive pulmonary disease (COPD) are associated with the presence of particulate matter 2.5 (PM2.5) in the air. In the present study, the effect of synthesized ursolic acid derivatives on mice model of PM2.5-induced COPD was investigated in vivo. The mice model of COPD was established by the administration of 25 µL of PM2.5 suspension through intranasal route daily for 1 week. The levels of oxidative stress markers and inflammatory cytokines like tumor necrosis factors-α and interleukin-6 in the mice bronchoalveolar fluids increased markedly on administration with PM2.5. However, treatment with ursolic acid derivative caused a significant suppression in PM2.5-induced increase in oxidative stress markers and inflammatory cytokines in dose-dependent manner. Hematoxylin and eosin staining showed excessive inflammatory cell infiltration in pulmonary tissues in mice with COPD. The inflammatory cell infiltration was inhibited on treatment of the mice with ursolic acid derivative. The ursolic acid derivative treatment increased level of superoxide dismutase in mice with COPD. The lung injury induced by PM2.5 in mice was also prevented on treatment with ursolic acid derivative. Thus, ursolic acid derivative inhibits pulmonary tissues damage in mice through suppression of inflammatory cytokine and oxidative enzymes. Therefore, ursolic acid derivative can be of therapeutic importance for treatment of PM2.5-induced COPD.

Study on a New Electromagnetic Flow Measurement Technology Based on Differential Correlation Detection.

Under the conditions of low flow rate and strong noise, the current electromagnetic flowmeter (EMF) cannot satisfy the requirement for measurement or separate the actual flow signal and interference signal accurately. Correlation detection technology can reduce the bandwidth and suppress noise effectively using the periodic transmission of signal and noise randomness. As for the problem that the current anti-interference technology cannot suppress noise effectively, the noise and interference of the electromagnetic flowmeter were analyzed in this paper, and a design of the electromagnetic flowmeter based on differential correlation detection was proposed. Then, in order to verify the feasibility of the electromagnetic flow measurement system based on differential correlation, an experimental platform for the comparison between standard flow and measured flow was established and a verification experiment was carried out under special conditions and with flow calibration measurements. Finally, the data obtained in the experiment were analyzed. The research result showed that an electromagnetic flowmeter based on differential correlation detection satisfies the need for measurement completely. The lower limit of the flow rate of the electromagnetic flowmeter based on the differential correlation principle could reach 0.084 m/s. Under strong external interferences, the electromagnetic flowmeter based on differential correlation had a fluctuation range in output value of only 10 mV. This shows that the electromagnetic flowmeter based on the differential correlation principle has unique advantages in measurements taken under the conditions of strong noise, slurry flow, and low flow rate.

Identification and Gene Expression Analysis of the Pheromone Biosynthesis Activating Neuropeptide Receptor (PBANR) From the Ostrinia furnacalis (Lepidoptera: Pyralidae).

Pheromonal communication is important in insect mate finding and reproduction. Identifying components of pest insect pheromone system is a first step to disrupt pest insect reproduction. In this study, we identified and cloned the pheromone biosynthesis activating neuropeptide receptor (PBANR) from the Asian corn borer, Ostrinia furnacalis (Guenée) (Lepidoptera: Pyralidae), which is one of the most damaging pests of corn and other crops in parts of Asia and Australia. The O. furnacalis PBANR (OstfuPBANR) gene has an ORF of 1,086 bp and encoded 362 amino acids with seven transmembrane domains and had a high sequence identity to known lepidopteran PBANRs. Expression analysis showed that OstfuPBANR was highly expressed in the pheromone glands compared with other tissues, consistent with other studies. Interestingly, OstfuPBANR was expressed higher in the larval stages compared to the pupal or adult stages, suggesting that OstfuPBANR may have broad functions in larva beyond adult pheromone synthesis.

Understanding the hydrogen transfer mechanism for the biodegradation of 2,4,6-trinitrotoluene catalyzed by pentaerythritol tetranitrate reductase: molecular dynamics simulations.

The explosive 2,4,6-trinitrotoluene (TNT) is a highly toxic pollutant. Biodegradation is inevitably one of the most cost-effective and enviromentally friendly means of removing TNT pollution. However, the aromatic derivatives from the reduction of nitro groups by several classic enzymes are still toxic. Besides the reduction of nitro groups, pentaerythritol tetranitrate reductase (PETNR) offers a potential route to ring fission and complete degradation of TNT through the pathway of the Meisenheimer complex. This work is devoted to deeply understand the essence of the Meisenheimer pathway and mainly focus on the crucial hydrogen-transfer reaction by means of molecular dynamics (MD) simulations. We obtain three valuable findings. Firstly, the parallel π-π stacking between TNT and the flavin mononucleotide (FMN) cofactor is a precondition. The key residue controlling this conformation is His181. Although His184 does not interact with TNT, the mutation from His184 to Asn184 would abolish the π-π structure. Secondly, the data of the empirical valence bond (EVB) show that the Meisenheimer pathway is predominant because its activation barrier is 6.7 kcal mol-1 far less than that of nitro reduction (26.6 kcal mol-1). Finally, based on the results of thermodynamic integration (TI), the type of transferred hydrogen is also ensured, that is, the H anion (H-) for the Meisenheimer complex and the H radical (H˙) for nitro reduction. Our findings provide an exhaustive understanding for the first hydrogen transfer reaction that has a decisive effect on two competing pathways, and help in searching for and designing new enzymes that can effectively degrade TNT.

Energy Modeling of IoT Mobile Terminals on WiFi Environmental Impacts †.

With the popularity of various IoT mobile terminals such as mobile phones and sensors, the energy problems of IoT mobile terminals have attracted increasingly more attention. In this paper, we explore the impacts of some important factors of WiFi environments on the energy consumption of mobile phones, which are typical IoT end devices. The factors involve the WiFi signal strength under good signal conditions, the type and the amount of protocol packets that are initiated by WiFi APs (Access Points) to maintain basic network communication with the phones. Controlled experiments are conducted to quantitatively study the phone energy impacts by the above WiFi environmental factors. To describe such impacts, we construct a time-based signal strength-aware energy model and packet type/amount-aware energy models. The models constructed in the paper corroborate the following user experience on phone energy consumption: (1) a phone's energy is drawn faster under higher WiFi signal strengths than under lower ones even in normal signal conditions; (2) phones consume energy faster in a public WiFi network than in a private one even in the basic phone state. The energy modeling methods proposed in the paper enable ordinary developers to analyze phone energy draw conveniently by utilizing inexpensive power meters as measurement tools. The modeling methods are general and are able to be used for phones of any type and any platform.

Molecular dynamics investigations of an indicator displacement assay mechanism in a liquid crystal sensor.

A recently reported liquid-crystal sensor system based on the substrate competitive inclusion effects of ß-cyclodextrin (ß-CD) has been investigated using molecular dynamics simulations in this work. In such a system, the released indicator could induce an orientational transition of liquid-crystals from planar to homeotropic. The analyte molecule can thus be easily and efficiently detected by observing the corresponding optical image changing from bright to dark. Here, the different binding affinity of ß-CD for the indicator (sodium dodecyl sulfate, SDS) and the analyte (methylene blue, MB) was identified using molecular dynamics simulations and absolute binding free energy calculations. The inclusion processes calculated using the adaptive biasing force algorithm can completely explain the competitive inclusion between MB and SDS by ß-CD, and thus lead to a significant change in the liquid crystal optical properties.

Single-site laparoscopic percutaneous extraperitoneal closure of the internal ring using an epidural and spinal needle: excellent results in 1464 children with inguinal hernia/hydrocele.

BACKGROUND: Laparoscopic percutaneous extraperitoneal closure (LPEC) of the internal ring is a well-developed procedure for pediatric inguinal hernia and hydrocele. To reduce the skin incisions and improve the cosmesis, single-site LPEC (SLPEC) has been developed with numerous techniques and instruments. In this study, we described our modifications of SLPEC using an epidural and spinal needle in a large pediatric population. METHODS: From February 2013 to February 2016, 1464 pediatric patients who underwent SLPEC in our hospital were retrospectively reviewed. A 5-mm laparoscope was introduced at the subumbilicus. An 18-gauge epidural needle with a silk suture loop was introduced into the corresponding skin of the internal ring. The needle was advanced extraperitoneally on the medial side of the ring. The suture loop was pushed into peritoneal cavity by the spinal needle. The epidural needle was withdrawn to the roof of the internal ring and then kept advancing along the lateral side. Aided by the spinal needle and laparoscope, a long suture loop was sent into the first loop in peritoneal cavity. The long suture loop was pulled out of the abdominal wall by picking up the first loop, and the internal ring was closed by knotting the suture extracorporeally. The contralateral patent processus vaginalis (CPPV) was simultaneously repaired if present. RESULTS: In total, 981 patients presented with inguinal hernia and 483 with hydrocele. A CPPV was present in 483 patients with unilateral pathology and thus simultaneously repaired. The hydrodissection technique and grasping forceps were used in 290 and 113 patients, respectively. The median operation time was 11 min (7-18 min) and 18 min (10-30 min) for unilateral and bilateral inguinal hernias/hydroceles, respectively. There was no development of intra- or postoperative complications. CONCLUSIONS: SLPEC using an epidural and spinal needle can be performed with excellent results in pediatric inguinal hernias and hydroceles.

[Treating irritable bowel syndrome with diarrhea patients by yigan fupi decoction: a randomized controlled trial].

OBJECTIVE: To evaluate the efficacy and safety of Yigan Fupi Decoction (YFD) in the treatment of irritable bowel syndrome with diarrhea (IBS-D) patients. METHODS: A randomized controlled clinical trail was carried out in patients with IBS-D. All patients were randomly assigned to the treatment group (58 cases, treated with YFD) and the control group (58 cases, treated with Pinaverium Bromide Tablet). The treatment course was 4 weeks for all patients. The total effective rate, the stool property and state, the quality of life (QOL), and TCM syndrome efficacy were assessed by IBS bowel symptom severity scale (IBS-BSS), IBS defecation state questionnaire (IBS-DSQ), IBS quality of life questionnaire (IBS-QOL), and traditional Chinese medicine pattern curative effect scoring system (TCM-PES) before and after treatment. RESULTS: There was no statistical difference in the total effective rate between the two groups (82.76% vs. 77.59%, P > 0.05). The treatment group was superior in the total IBS-BSS integral to the control group (P < 0.05). The total effective rate of improving the stool property was better in the treatment group than in the control group (81.03% vs. 72.41%, P < 0.05). Besides, the number of days for emergent defecation among 10 days was less in the treatment group than in the control group (P < 0.05). The improvement of the total IBS-QOL integral and the total integral of TCM syndrome were better in the treatment group than in the control group (P < 0.01). The total effective rate of TCM-PES was better in the treatment group than in the control group (84.48% vs. 70.69%, P < 0.05). CONCLUSION: YFD was effective in the treatment of IBS-D patients of Gan-qi invading Pi syndrome, and could effectively relieve bowel symptoms, improve the stool property and the defecation frequency, elevate their QOL, and attenuate Gan-qi invading Pi syndrome with favorable safety and compliance.

Effectiveness of an ERAS-based exercise-nutrition management model in enhancing postoperative recovery for thoracoscopic radical resection of lung cancer: A randomized controlled trial.

BACKGROUND: To analyze the effect of an exercise-nutrition management model based on the Enhanced Recovery After Surgery (ERAS) concept on patients undergoing thoracoscopic radical surgery for lung cancer. METHODS: From June 2019 to December 2022, 85 lung cancer patients who underwent thoracoscopic radical lung cancer surgery were randomly divided into 2 groups. The control group, consisting of 42 patients, received routine nursing care during the perioperative period. The study group, comprising 43 patients, implemented an exercise-nutrition management model based on the ERAS concept during the perioperative period. We compared general data, perioperative indicators, compliance, and complications between the 2 groups. Additionally, we assessed the nutritional status using the patient-generated subjective global assessment (PG-SGA), albumin (ALB), prealbumin (PA), and hemoglobin (Hb), as well as lung function, including forced expiratory volume in the first second (FEV1) and maximum voluntary ventilation (MVV), in the patient population following the Piper intervention. RESULTS: In the study group, the times to first defecation and getting out of bed, the duration of thoracic drainage tube indwelling, and the length of hospital stay were shorter than those in the control group. The VAS scores on the 2nd and 3rd postoperative days were lower in the study group than in the control group (P < .05). Medication compliance was higher in the study group compared to the control group (P < .05). Post-intervention, the PG-SGA scores in the study group were lower, while PA, ALB, and Hb levels were higher than those in the control group (P < .05). The MVV, FEV1, and FVC values were higher in the study group than in the control group after the intervention (P < .05). The PFS and mMRC scores were lower in the study group compared to the control group after the intervention, and the QLQ-C30 scores were higher (P < .05). The incidence of complications was 6.98% in the study group, which was not significantly different from 11.90% in the control group (P > .05). CONCLUSION: The exercise-nutrition management model, based on the ERAS concept, exhibits significant perioperative effects in patients undergoing thoracoscopic radical resection of lung cancer, improving their nutritional status and reducing complications.
