ObjectiveTo explore the driving forces for oncology nurses’ participation in palliative care work, thereby providing a theoretical basis for the improvement of education and training, incentive mechanisms, and other aspects of the palliative care nursing staff. MethodsEmploying a qualitative research method, semi-structured interviews lasting 40-60 minutes were conducted with 14 nurses who had participated in palliative care work. The interview data were analyzed using the Colaizzi seven-step analysis method. ResultsInternal positive driving forces were job interest, empathy, and a sense of professional responsibility, while the negative was low psychological resilience. External positive driving forces included high work support, professional identity, mutual benefits for nurses and patients, and positive patient attitudes, whereas negative driving forces comprised busy routine clinical work, lack of a reward and incentive system, and bland or negative patient attitudes. ConclusionIt is essential to provide a flexible platform for the enhancement of nurses’ professional capabilities in palliative care, intensify the publicity of palliative care and death education; intervene and guide nurses’ negative emotions, improve and implement relevant incentive systems, and standardize the job recognition and scope of responsibilities of palliative care nurses.

ObjectiveTo explore the mechanism of Shenmai injection in improving cisplatin resistance in non-small cell lung cancer (NSCLC) based on the endoplasmic reticulum stress through protein kinase R-like endoplasmic reticulum kinase (PERK)/activated transcription factor 4 (ATF4)/C/EBP homologous protein (CHOP) signaling pathway. MethodsBALB/c nude mice bearing cisplatin-resistant human lung cancer cell line (A549/cisplatin) were randomly divided into four groups: Blank control group (0.9% sodium chloride), cisplatin group (5 µg·g-1cisplatin), Shenmai injection group (5.2 mg·g-1 Shenmai injection), and combination therapy group (5.2 mg·g-1 Shenmai injection +5 µg·g-1cisplatin). The drug intervention lasted for 4 weeks, and the changes in body weight and tumor volume were monitored. Hematoxylin-eosin (HE) staining was performed to observe tumor tissue pathology. Transmission electron microscopy (TEM) was used to assess the morphology of the endoplasmic reticulum. Immunohistochemical assay was conducted to measure the positive expressions of PERK, ATF4, and CHOP in tumor tissues. Western blot quantified the protein expression of immunoglobulin heavy chain binding protein (BIP), PERK, phosphorylated PERK (p-PERK), eukaryotic translation initiation factor 2α (eIF2α), phosphorylated eIF2α (p-eIF2α), ATF4, CHOP, B-cell lymphoma -2 (Bcl-2), and Bcl-2 Associated X protein (Bax). A549/cis cells were divided into blank group: Blank control group (normal culture medium), cisplatin group (23.3 µmol·L-1 cisplatin), Shenmai Injection group (20 g·L-1 Shenmai injection), and combination therapy group (20 g·L-1 Shenmai injection+23.3 µmol·L-1 cisplatin). Cell counting kit-8 (CCK-8) method was used to detect cell viability, TEM was used to observe the morphology of endoplasmic reticulum, and Western blot was used to detect endoplasmic reticulum stress and apoptosis-related proteins. ResultsCompared with the cisplatin group, the combination therapy group showed increased body weight (P<0.05), decreased tumor volume (P<0.05), and expanded endoplasmic reticulum in tumor cells. The positive expressions of PERK, ATF4, and CHOP increased (P<0.05). Western blot revealed elevated protein expression levels of BIP, p-PERK/PERK, p-eIF2α/eIF2α, ATF4, CHOP, and Bax (P<0.05), while Bcl-2 expression decreased (P<0.05). As shown in the in vitro experiment, compared with the cisplatin group, the combination therapy group exhibited a reduced cell survival rate (P<0.05). TEM revealed increased endoplasmic reticulum dilation and vesicular degeneration. Western blotting showed increased protein levels of BIP, p-PERK/PERK, p-eIF2α/eIF2α, ATF4, CHOP and Bax (P<0.05), with decreased Bcl-2 expression (P<0.05). ConclusionShenmai injection combined with cisplatin has a synergistic antitumor effect in NSCLC, which may be attributed to the activation of endoplasmic reticulum stress response mediated by the PERK/eIF2α/ATF4/CHOP signaling pathway and the induction of tumor cell apoptosis.

Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10
/L vs preoperative 3.07×10
/L, P<0.001), with significant upregulation of CD11b (7.30×10
/L vs preoperative 3.05×10
/L, P<0.001) and CD54 (7.15×10
/L vs preoperative 2.99×10
/L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10
/L vs preoperative 1.12×10
/L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10
/L vs preoperative 1.12×10
/L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

Objective To analyze the infection status and epidemic trends of soil-borne nematode infections in Yubei, Chongqing City, in 2010,2021, and 2022. Methods The local populations from four survey sites of four towns in 2010 and five sites of five towns in 2021 and 2022 were surveyed regarding their basic information using a unified form. Fecal samples of the participants were collected and tested for soil-borne nematode infections using the modified Kato-Katz thick smear method. Results In 2010, 2 049 participants were surveyed, followed by 1 000 participants in 2021 and 2022. The overall prevalence of parasitic infections declined significantly from 3.86% to 0.20%. In 2010, soil-transmitted nematode included hookworms(3.81%) and roundworms(0.29%). In 2021, the infection rates of roundworms and hookworms were 1.70% and 0.10% respectively. Notably, only Ascaris was identified in 2022(0.20%). The≥60 age group consistently exhibited the highest infection rates across all surveys, followed by the 40-59 age group. The infection rates of males in the three surveys were 3.31%,1.92%, and 0.20% respectively, and those of females were 4.37%, 1.46%, and 0.20% respectively. There was no statistically significant difference in the infection rates between males and females. Educational attainment was inversely associated with infection; in 2010, the highest prevalence was observed among those with primary education or below, whereas in 2021, illiterate or semi-literate individuals showed the highest susceptibility. The occupational distribution of infections in 2010 indicated that retirees (8.33%), farmers(4.86%), and homemakers or unemployed individuals(3.45%)were the most affected. However, in 2021 and 2022, farmers emerged as the predominant occupational group with soil-transmitted nematode infections. Conclusions The infection rate of soil-borne nematodes showed a decreasing trend in Yubei, and the infection species changed from hookworms in 2010 to Ascaris in 2022. Farmers, the elderly, and people with low education levels should continue to be the focus of preventive and control efforts.

OBJECTIVE:
To investigate the effects of Bushen Huoxue Granule on the ubiquitin-proteasome system (UPS) in an in vitro model of Parkinson's disease.
METHODS:
After treated with 1-methyl-4-phenylpyridinium (MPP+, 1 mmol/L) for 24 h, the cells were incubated with drug-free serum, Madopar-containing serum or Bushen Huoxue Granule-containing serum (BCS, 5%, 10%, and 20%) for another 24 h. The levels of α-synuclein (α-syn), tyrosine hydroxylase (TH) and UPS-related proteins were detected by Western blot. The expression levels of α-syn in PC12 cells were also analyzed by Western blot after treated with proteasome inhibitor MG132 and WT-α-syn plasmid transfection, respectively, as well as the alterations induced by subsequent BCS intervention. Immunocytochemistry was performed to determine the changes in α-syn phosphorylation at serine 129 (pSer129-α-syn) expression. The 20S proteasome levels were measured by enzyme-linked immunosorbnent assay.
RESULTS:
BCS (volume fraction ⩽20%) intervention could alleviate the MMP+-induced cell viability decrease (P<0.05). In the MPP+ treated cells, α-syn was up-regulated, while TH and proteins of UPS such as ubiquitin (Ub), Ub binding with Ub-activating enzyme (UBE1), Parkin and Ub C-terminal hydrolase-1 (UCHL-1) were down-regulated (P<0.05). BCS intervention could attenuate the above changes (P<0.05). The activity of BCS on blocking α-syn accumulation was weakened by MG132 (P<0.05). While α-syn level was significantly increased in cells transfected with plasmid, and reduced by BCS intervention (P<0.05). pSer129-α-syn was increased in MPP+-induced PC12 cells, whereas decreased by later BCS intervention (P<0.05). The 20S proteasome activity of MPP+-induced PC12 cells was decreased, but increased after BCS intervention (P<0.05).
CONCLUSION
BCS intervention protected UPS function, increased 20S proteasome activity, promoted pathological α-syn clearance, restored cell viability, and reversed the damage caused by MPP+ in the in vitro model of Parkinson's disease.

OBJECTIVES:
To investigate the efficacy and safety of empagliflozin in patients with glycogen storage disease (GSD)-associated inflammatory bowel disease (IBD).
METHODS:
A cross-sectional study was conducted, enrolling 25 patients with GSD-associated IBD who received empagliflozin treatment. General data, details of empagliflozin use, and adverse events were collected. Clinical symptoms and biochemical parameters before and after empagliflozin therapy were compared.
RESULTS:
Twenty-five patients with GSD-associated IBD were included, with a median age at diagnosis of 0.7 years, and a mean age at initiation of empagliflozin therapy of (11 ± 6) years. The initial dose of empagliflozin was (0.30 ± 0.13) mg/(kg·d), with a maintenance dose of (0.40 ± 0.21) mg/(kg·d), and a treatment duration of (34 ± 6) months. Seventy-eight percent (18/23) of patients' parents reported that empagliflozin therapy reduced the frequency of infections and oral ulcers, and increased neutrophil counts. Clinically, the number of patients with anorexia decreased from 12 to 5 after treatment, and 30% showed improved appetite (P<0.05). The numbers of patients with diarrhea, mucus/bloody stools, perianal disease, and oral ulcers decreased from 19, 9, 11, and 21 before treatment to 7, 1, 0, and 10 after treatment, respectively (P<0.05). Laboratory findings showed that absolute neutrophil counts increased, while platelet counts, lactate, and uric acid levels decreased significantly after empagliflozin treatment (P<0.05). Adverse reactions occurred in 7 patients (28%) during empagliflozin treatment. Two cases occurred in the treatment initiation phase, presenting as hypotension or profuse sweating with dehydration, along with urinary tract infections (UTIs); empagliflozin was discontinued in both cases. During the maintenance phase, 3 cases of UTIs and 2 cases of hypoglycemia (one with profuse sweating) were reported.
CONCLUSIONS
Empagliflozin therapy can increase neutrophil counts, reduce the incidence of infections and oral ulcers, alleviate diarrhea and abdominal pain, improve appetite, and ameliorate platelet count, lactate, and uric acid levels in patients with GSD-associated IBD, demonstrating significant clinical benefit. UTIs, hypoglycemia, hypotension, profuse sweating, and dehydration may be potential adverse reactions associated with empagliflozin therapy.

OBJECTIVE:
To assess the safety and topical efficacy of prim-O-glucosylcimifugin (POG) and investigate the molecular mechanisms of its therapeutic effects in atopic dermatitis (AD).
METHODS:
The effects of POG on human keratinocyte cell viability and its anti-inflammatory properties were evaluated using cell counting kit-8 assay and reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Subsequently, the impact of POG on the differentiation of cluster of differentiation (CD) 4+ T cell subsets, including T-helper type (Th) 1, Th2, Th17, and regulatory T (Treg), was examined through in vitro experiments. Network pharmacology analysis was used to elucidate POG's therapeutic mechanisms. Furthermore, the therapeutic potential of topically applied POG was further evaluated in a calcipotriol-induced mouse model of AD. The protein and transcript levels of inflammatory markers, including cytokines, lymphocyte-specific protein tyrosine kinase (Lck) mRNA, and LCK phosphorylation (p-LCK), were quantified using immunohistochemistry, RT-qPCR, and Western blot analysis.
RESULTS:
POG was able to suppress cell proliferation and downregulate the transcription of interleukin 4 (Il4) and Il13 mRNA. In vitro experiments indicated that POG significantly inhibited the differentiation of Th2 cells, whereas it exerted negligible influence on the differentiation of Th1, Th17 and Treg cells. Network pharmacology identified LCK as a key therapeutic target of POG. Moreover, the topical application of POG effectively alleviated skin lesions in the calcipotriol-induced AD mouse models without causing pathological changes in the liver, kidney or spleen tissues. POG significantly reduced the levels of Il4, Il5, Il13, and thymic stromal lymphopoietin (Tslp) mRNA in the AD mice. Concurrently, POG enhanced the expression of p-LCK protein and Lck mRNA.
CONCLUSION
Our research revealed that POG inhibits Th2 cell differentiation by promoting p-LCK protein expression and hence effectively alleviates AD-related skin inflammation.
