Objective:To explore the relationship between post-traumatic growth and stress perception as well as the chain-mediated roles of psychological resilience and navigating social support in patients with primary liver cancer(PLC), in order to provide theoretical ideas for the nursing and intervention of PLC patients.Methods:Convenience sampling was used to select PLC patients admitted to the First Affiliated Hospital, Third Affiliated Hospital, and Fourth Affiliated Hospital of Xinjiang Medical University from October 2023 to May 2024 as the research subjects. A cross-sectional survey was conducted using Posttraumatic Growth Inventory, the Chinese Perceived Stress Scale, Perceived Social Support Scale, and the Connor-Davidson Resilience Scale.Results:A total of 236 PLC patients were ultimately included, including 189 males and 47 females. Age distribution was as follows: 18-40 years years (7 cases), 41-60 years (128 cases), and ≥61 years (101 cases). Posttraumatic growth showed a significant negative correlation with perceived stress ( r=-0.512, P<0.01), while demonstrating positive correlations with psychological resilience and perceived social support ( r=0.605, 0.515, both P<0.01). Psychological resilience and perceived social support had mediating and chain mediating effects between perceived stress and posttraumatic growth, with mediating effects of -0.176 and -0.069, accounting for 29.24% and 11.46% of the total effect, respectively. The chain mediating effect value was 0.073, accounting for 12.13% of the total effect. Conclusions:The pathway of stress perception on post-traumatic growth in patients with PLC is indirect, and stress perception can contribute to the growth of post-traumatic growth in patients through psychological resilience, and navigating social support.

OBJECTIVE To optimize the stir-frying process of Platycodon grandiflorum,compare the protective effect of P.grandiflorum on lung injury in mice before and after stir-frying,and preliminarily explore the characteristics of"enhanced efficacy through processing"of stir-frying P.grandiflorum.METHODS On the basis of single-factor experiment,the stir-frying time,temperature and frequency were taken as factors,and the comprehensive scores of appearance traits,platycodin D content and alcohol extract content were taken as indexes.Box-Behnken response surface experiment was designed to optimize the stir-frying process of P.grandiflorum and verify it.The mice were divided into blank control group,model group,dexamethasone group(positive control drug,5 mg/kg),P.grandiflorum low-dose and high-dose groups(0.6,1.2 g/kg),fried P.grandiflorum low and high dose groups(0.6,1.2 g/kg),with 8 mice in each group.The treatment was given once a day for 10 consecutive days.After the last administration,acute lung injury model was established by intratracheal instillation of lipopolysaccharide.The levels of interleukin-6(IL-6),IL-1β,tumor necrosis factor-α(TNF-α)in serum and superoxide dismutase(SOD),myeloperoxidase(MPO)and malondialdehyde(MDA)in lung tissue were detected,lung wet/dry weight ratio and thymus index were calculated,and the pathological changes of lung tissue were observed.RESULTS The optimum processing conditions were as follows:stir-frying temperature of 120℃,stir-frying time of 12 min,stir-frying frequency of 19 r/min;the comprehensive scores of the three batches of process verification were all greater than 97 points,RSD＜3%(n=3).The results of pharmacodynamic experiments showed that compared with blank control group,the lung dry-wet weight ratio as well as the levels of IL-6,IL-1β,TNF-α,MPO and MDA in the model group were significantly increased(P＜0.01),the thymus index and SOD level were significantly decreased(P＜0.01),and the lung tissue was significantly damaged.Compared with model group,above indexes of the mice in each administration group were significantly improved(P＜0.01),and the lung tissue injury was significantly reduced.At the same dose,except for the lung dry-wet weight ratio,the above indexes of the mice in the stir-fried P.grandiflorum groups were significantly improved compared with P.grandiflorum groups(P＜0.05),and the lung tissue damage was further reduced.CONCLUSIONS The optimized stir-frying process is stable and feasible.The protective effect of stir-fried P.grandiflorum on acute lung injury in mice is better than that of raw products at the same dosage.

Objective To explore the expression profile of adenosine A1 receptor in the paraventricular thalamic nucleus(PVT)in wakefulness/sleep state and its role in regulating sleep.Methods Male C57BL/6J mice(6～12 weeks old,weighing 22～28 g)were randomly divided into ZT0,ZT6,ZT10,ZT12,and sleep deprivation and recover0y sleep groups(n=16 or n=4).RT-qPCR and fluorescence in situ hybridization were used to observe the changes of adenosine A1 receptor in PVT.Whole-cell patch-clamp recording was conducted to determine the effects of adenosine on the membrane potential and discharge frequency of PVT neurons.The experimental animals were divided into adenosine A1 receptor interference group(n=8)and interference control group(n=7).After RNA interference,electroencephalography(EEG)and electromyography(EMG)were applied simultaneously to observe the changes in wake and sleep time between the 2 groups during sleep deprivation for 6 h and sleep recovery for 4 h.Results RT-qPCR and fluorescence in situ hybridization confirmed that the expression of adenosine A1 receptor in PVT was affected by wakefulness/sleep state,with the level in the ZT0 group(active stage)significantly higher than that in the ZT12 group(non-active stage,P<0.05).Whole-cell patch clamp recording indicated that adenosine exerted inhibitory effects on PVT neurons through 2 distinct response types(P<0.05),and the inhibition was in a diminishing trend with a decrease in the expression level of adenosine A1 receptor.After sleep deprivation,the expression level of adenosine A1 receptor showed significant intergroup differences:the level was significantly higher in the sleep deprivation group than the recovery sleep group(P<0.05),while that of the recovery sleep group was higher than that of the ZT6 group and that of the ZT10 group(P<0.05).After knocking down adenosine A1 receptor(shRNA-A1R)in the PVT,the wakefulness timing of the shRNA-A1R group was significantly increased,while the sleep timing was significantly decreased within 1 h after sleep recovery when compared with the interference control group(P<0.05).Conclusion The expression of adenosine A1 receptor in the PVT is dynamically regulated by sleep pressure,which was increasing as sleep pressure rises.

Objective:To explore the associated factors for membranous nephropathy (MN) patients with IgM deposition, and to construct a prediction model.Methods:This study was a retrospective cohort study. Patients diagnosed with MN with IgM deposition by renal biopsy in the Fourth Hospital of Hebei Medical University from February 2017 to December 2023 were retrospectively included. Clinical and pathological data were collected. The study population was randomized into a training set and a validation set at a 7:3 ratio. The endpoint event was defined as the remission of MN, and the patients were divided into remission group and non-remission group to compare the clinical and pathological examination results. Least absolute shrinkage and selection operator regression analysis and Cox regression analysis were used to explore the associated factors of poor prognosis of MN patients with IgM deposition. Internal validation was conducted using the validation set data. The clinical efficacy of the predictive model was evaluated by calculating the area under the receiver operating characteristic (ROC) curve and generating calibration curves. The total nomogram score for each patient was calculated based on the training set data, and the predictive performance was assessed by plotting the ROC curve. Patients were then stratified into low-risk and high-risk groups according to the optimal cut-off value derived from the ROC analysis of the total nomogram score. Kaplan-Meier survival analysis was performed to compare the remission rate between the two groups. Model performance was evaluated using the validation set.Results:A total of 200 MN patients with IgM deposition were included, and 49.0% of them achieved clinical remission. In the training set, statistically significant differences were observed in 24-hour urine protein quantification ( Z=-2.638, P=0.008), renal arteriolar wall thickening ( χ2=6.891, P=0.009), the proportion of patients receiving immunosuppressive therapy ( χ2=21.381, P<0.001), and the proportion of patients treated with corticosteroids combined with cyclophosphamide ( χ2=10.107, P=0.001). Through least absolute shrinkage and selection operator regression and Cox regression, 2 factors associated with clinical remission in MN patients with IgM deposition were simultaneously identified from 16 potential associated factors, including the use of immunosuppressants ( HR=3.823, 95% CI 2.055-7.113, P<0.001), and renal arteriolar wall thickening ( HR=0.428, 95% CI 0.221-0.831, P=0.012). Incorporating the clinical measurement of phospholipase A2 receptor (PLA2R) antibodies, a predictive model was established. The performance of the model was evaluated using the training dataset, yielding an area under the ROC curve of 0.731 (95% CI 0.648-0.814), with a sensitivity of 88.7% and a specificity of 55.1%. The optimal cut-off value was a total nomogram score of 41.7 points. The Kaplan-Meier survival analysis showed that the remission rate was significantly higher in the low-risk group than that of the high-risk group (Log-rank test, χ2=33.525, P<0.001). Model validation was performed using the validation dataset, which showed an AUC of 0.715 (95% CI 0.591-0.839), sensitivity of 70.4%, and specificity of 63.6%. Similarly, the Kaplan-Meier survival analysis demonstrated a significantly higher remission rate in the low-risk group than in the high-risk group (Log-rank test, χ2=8.467, P=0.004). Conclusion:A nomogram predictive model for remission of MN patients with IgM deposition, based on serum PLA2R antibody levels, the use of immunosuppressive therapy, and renal arteriolar wall thickening is developed. The model demonstrates a moderate clinical applicability.

ObjectiveTo explore the effects of modified Danggui Beimu Kushen pills on tumor growth and T-cell subsets in H22 hepatocellular carcinoma-bearing mice and to provide an experimental basis for the treatment of hepatocellular carcinoma with modified Danggui Beimu Kushen pills combined with immune checkpoint antibodies. MethodA H22 hepatocellular carcinoma-bearing mouse model was established. The modeled mice were randomized into model， cisplatin， low- （4 g·kg^-1·d^-1）， medium- （8 g·kg^-1·d^-1）， and high-dose （16 g·kg^-1·d^-1） modified Danggui Beimu Kushen pills groups. After continuous administration for 14 days， the mice were sacrificed on day 15. The tumor volume was measured on days 0， 4， 8， 12， 15 of drug administration. Tumors were weighed and thymus index and spleen index were calculated. Spleen lymphocytes were co-cultured with H22 hepatoma cells， and the tumor cell-killing rate was detected by the cell counting kit-8 （CCK-8）. Real-time polymerase chain reaction was carried to determine the mRNA levels of programmed cell death protein-1 （PD-1） and lymphocyte activation gene-3 （LAG-3） in spleen and tumor tissues. The number of CD4⁺ and CD8⁺ T cells and the expression of PD-1 and LAG-3 were detected by immunohistochemistry （IHC）. ResultOn day 8 of drug administration， tumor volumes in all treatment groups decreased compared with that in the model group. On day 15， both tumor volume and tumor weight were significantly lower in the treatment groups than in the model group （P<0.01）， with the cisplatin group showing the most pronounced reduction. Compared with the model and cisplatin groups， medium- and high-dose modified Danggui Beimu Kushen pills increased the thymus index （P<0.01）. Compared with the model group， all treatment groups showed increased spleen index （P<0.05， P<0.01）， with the cisplatin group showing the most significant increase. Compared with the model and cisplatin groups， all the groups of modified Danggui Beimu Kushen pills demonstrated increased number of CD4⁺ and CD8⁺ T cells and tumor cell-killing rate in the spleen and tumor tissues （P<0.01） and down-regulated mRNA and protein levels of LAG-3 （P<0.05， P<0.01）. The high-dose group of modified Danggui Beimu Kushen pills had lower mRNA level of PD-1 in the tumor tissue than the model and cisplatin groups （P<0.01）. ConclusionModified Danggui Beimu Kushen pills may promote the proliferation and tumor microenvironment infiltration of CD4⁺ and CD8⁺ T cells in H22 tumor-bearing mice by down-regulating LAG-3 expression， thereby improving T-cell immune activity and inhibiting tumor growth. This study provides an experimental basis for the combination of modified Danggui Beimu Kushen pills and immune checkpoint antibodies in the treatment of hepatocellular carcinoma.

Objective:Evaluate the safety of the bioresorbable scaffold (BRS) series implanted.Methods:This is a cohort study, which included 377 patients with acute coronary syndrome (ACS) who underwent elective percutaneous coronary intervention (PCI) with Neovas-BRS implantation from July 2019 to April 2022 at the Northern Command General Hospital. The patients were divided into the series BRS group ( n=63) and single BRS group ( n=314). We compared PCI related data between two groups, as well as all-cause death, cardiac death, non-fatal myocardial infarction, target vessel revascularization, stroke, and bleeding of type 2 to 5 defined by the Bleeding Academic Research Consortium of America (BARC) during follow-up. We also compared the major adverse cardiovascular and cerebrovascular events (MACCE), which includes all-cause death, non-fatal myocardial infarction, target vessel revascularization and stroke, as well as the net adverse clinical events (NACE), which includes MACCE and bleeding of BARC type 2 to 5. Procedural immediate success was defined as a residual stenosis of<20% with successful stent implantation and post-PCI target vessel flow grade up to TIMI 3. The images of 11 patients in the series BRS group who underwent optical coherence tomography (OCT) were analyzed. Results:A total of 377 patients were finally enrolled, aged (52.5±10.7) years, including 80.4% (303/377) males . The immediate success rate of PCI was 100% in both groups. The number of ≥50% stenotic lesions, number of target vessels, SYNTAX score, number of post-application expansion balloons, number of guidewires, total stent length, contrast volume and operation time were higher in the series BRS group than in the single BRS group (all P<0.05). There was no significant difference in the proportion of intravascular ultrasound and OCT application between the two groups. One patient in the single BRS group had an ischemic stroke during postoperative hospitalization, but there were no death, non-fatal myocardial infarction, target vessel revascularization, or BARC 2 to 5 bleeding events occurred during hospitalization in both groups. Follow up time was 352.0 (193.0, 421.0) days. There was no statistically significant difference between the two groups in the incidence of all-cause death (0 vs. 0.6% (2/314), P=1.000), cardiogenic death (0 vs. 0.3% (1/314), P=1.000), nonfatal myocardial infarction (0 vs. 1.0% (3/314), P=1.000), target lesion revascularization (3.2% (2/63) vs. 1.6% (5/314), P=0.736), BARC type 2 to 5 bleeding (3.2% (2/63) vs. 5.7% (18/314), P=0.604), MACCE (3.2% (2/63) vs. 2.9% (9/314), P=0.894), and NACE (6.3% (4/63) vs. 8.6% (27/314), P=0.553) during the follow-up period. OCT results of the 11 (17.5%) patients in the series BRS group indicated that 3 patients (27.3%) achieved non-overlapping connection, and the immediate stent expansion rate was (95.47±0.04) %. In 8 patients with BRS overlapping connections, immediate stent expansion rate was (90.32±0.44) %. Conclusion:In patients with low to intermediate-risk ACS, serial implantation of RBS in long coronary lesions is safe and feasible, and achieves the similar short-term outcomes as single BRS implantation.
