Objective:To examine the influence of physical function status on supportive care needs (SCNS) in patients with primary liver cancer (PLC) and to explore the mediating roles of perceived social support and anxiety-depression, with the aim of providing evidence for nursing interventions to improve patients' care experience.Methods:A convenience sampling method was used to select PLC inpatients admitted to The First Affiliated Hospital of Jinan University between December 2022 and February 2024. Data were collected using a general information questionnaire, the 34-item Supportive Care Needs Survey-Short Form, the Hospital Anxiety and Depression Scale, the Perceived Social Support Scale, and the Karnofsky Performance Status Scale to conduct a cross-sectional survey. Pearson correlation analysis was performed to examine associations among SCNS, perceived social support, anxiety-depression, and physical function status. Structural equation modeling was used to assess the mediating effects of perceived social support and anxiety-depression on the relationship between physical function status and SCNS.Results:A total of 304 patients were enrolled, including 260 males and 44 females, 31 cases aged 18-40 years old, 160 cases aged 41 to 60 years old, and 113 cases over 60 years old. The mean total SCNS score was (98.32 ± 21.75) points, the mean anxiety-depression score was (23.31 ± 9.64) points, the mean perceived social support score was (56.62 ± 13.05) points, and the mean physical function status score was (66.28 ± 12.31) points. Pearson correlation analysis showed that physical function status was negatively correlated with SCNS and anxiety-depression ( r =-0.509, -0.447; both P<0.05) and positively correlated with perceived social support ( r =0.439, P<0.05). Physical function status had a direct effect of 60.74% on SCNS, with specific mediating effects of perceived social support and anxiety-depression accounting for 23.15% and 11.85%, respectively, and a chain mediating effect of 4.26%. Conclusions:Patients with PLC exhibited a moderately high level of supportive care needs. Physical function status not only exerted a direct negative effect on SCNS but also indirectly influenced SCNS through the chain mediation of perceived social support and anxiety-depression. Clinical medical staff should focus on enhancing patients' perception of social support and effectively alleviating anxiety and depressive symptoms, thereby reducing supportive care needs to some extent.

Objective:To explore the effect of intervention model based on comprehensive nutrition management on glucose and lipid metabolism and pregnancy outcome in patients with gestational diabetes mellitus (GDM).Methods:104 GDM patients admitted to Shanxi Bethune Hospital from February 2022 to March 2023 were randomly divided into control group and experimental group, with 52 cases in each group. The control group implemented routine management measures and nutrition guidance, while the experimental group implemented an intervention model based on comprehensive nutrition management on the basis of routine management. The indexes of glucose and lipid metabolism (glycosylated hemoglobin, fasting blood glucose, 2 h postprandial blood glucose, total cholesterol, triglyceride and low density lipoprotein cholesterol), pregnancy outcome, self-management ability and self-efficacy were compared between the two groups before and after intervention.Results:Before the intervention, there was no significant difference in general situation, glucose and lipid metabolism index, self-management ability and self-efficacy between the two groups ( P>0.05). After the intervention, the level of glucose and lipid metabolism index in the experimental group was significantly lower than that in the control group, with statistical significance ( P<0.05). The incidence of adverse pregnancy outcome in the experimental group was significantly lower than that in the control group, with statistical significance ( P<0.05). The scores of self-management ability and self-efficacy in the experimental group were significantly higher than those in the control group, with statistical significance ( P<0.05). Conclusion:The intervention model based on comprehensive nutrition management can effectively improve the glucose and lipid metabolism index and pregnancy outcome of GDM patients, and significantly improve their self-management ability and self-efficacy related to nutrition management, which has high clinical application and promotion value.

OBJECTIVE To investigate the regulatory effects of couplet medicinals of Atractylodes macrocephala-Aucklandia lappa on gut microbiota and short-chain fatty acids （SCFAs） in the diarrhea-type irritable bowel syndrome （IBS-D） rats with spleen deficiency. METHODS The IBS-D rat model with spleen deficiency was induced by intragastric administration of Senna alexandrina combined with restraint stimulation. The model rats were divided into model group， positive control group （pinaverium bromide 1.5 mg/kg）， A. macrocephala-A. lappa low-dose， medium-dose and high-dose groups （0.7， 1.4， 2.8 g/kg）， with 6 rats in each group. Another 6 healthy rats were taken as the blank control group. The blank control group and the model group were given normal saline intragastrically， and other groups were given relevant drug liquid intragastrically， once a day， for consecutive 14 days. The general characteristics of rats and fecal water content were observed， and intestinal sensitivity [evaluating by abdominal wall withdrawal reflex （AWR） threshold] and the intestinal propulsion rate were determined. The serum levels of 5- hydroxytryptamine（5-HT）and SP were detected， and the pathological changes of colon tissue were observed； the protein expressions of 5-HT-3 receptor（5-HT3R）， 5-HT4R and 5-HT transporter（SERT） in colon tissue of rats were detected. 16S rRNA sequencing was performed for the feces of rats in blank control group， model group and A. macrocephala-A. lappa high-dose group； the contents of acetic acid， propionic acid and butyric acid in the feces of the rats were determined. RESULTS Compared with the model group， the body weight after 7 and 14 days of medication， fecal water content， AWR threshold， and the protein expressions of 5-HT4R and SERT in colon tissue were increased significantly in the A. macrocephala-A. lappa medium-dose and high-dose groups （P＜0.05 or P＜0.01）； serum contents of 5-HT and SP， intestinal propulsion rate （except for A. macrocephala-A. lappa medium-dose group）， the protein expression of 5-HT3R in colon tissue were decreased significantly （P＜0.01）； diarrhea relief， mental state recovery， and partially recovery of the structure of colon tissue were all found； moreover， the diversity and species number of gut microbiota were reduced in A. macrocephala-A. lappa high-dose group and the content of butyric acid in fecal samples was significantly reduced （P＜0.05）. CONCLUSIONS The compatibility of A. macrocephala and A. lappa can improve intestinal motility and sensitivity of IBS-D model rats with spleen deficiency， and alleviate diarrhea. This may be related to improving changes in intestinal microbiota structure， reducing 5-HT expression and butyric acid content， and increasing 5-HT4R and SERT expression.

Objective To investigate the mechanism of Guizhi Tongluo Tablets(GZTLP)on improving atherosclerosis in APOE knockout mice by regulating neutrophil extracellular trapping nets(NETs).Methods After modeling,24 APOE knockout mice aged 8 weeks were randomly divided into 4 groups:GZTLP high-dose group,low-dose group,model control group and normal control group,with 6 mice in each group.GZTLP was given 1.87 mg·g-1 and 0.47 mg·g-1 intragastric administration in high-dose group and low-dose group,respectively.The normal control group and model control group were given 0.9%sodium chloride solution intragastric administration for 6 weeks,and the lipid plaque deposition in aorta was observed by gross oil red O staining.Lipid deposition in aortic root was observed by oil red O staining.The pathological changes of lipid plaques in aortic root were observed by HE staining.The levels of interleukin-1β(IL-1β)and tumor necrosis factor α(TNF-α)in peripheral blood of mice were detected by enzyme-linked immunosorbent assay(ELISA).The expression of lymphocyte antigen 6G(Ly6G),myeloperoxidase(MPO)and citrulinated histone(Cit-H3)in plaques of the aortic arch and the colocalization of Ly6G,MPO and Cit-H3 were detected by immunofluorescence assay.Results Compared with the normal control group,the aorta of mice in the model control group showed serious lipid plaque deposition,morphological damage,and a large number of inflammatory cells infiltration,the contents of serum inflammatory factors IL-1β and TNF-α were increased,and the protein expressions of Ly6G,Cit-H3 and MPO were significantly increased.Compared with model control group,GZTLP group reduced the amount of lipid plaque deposition in aorta,the arrangement of aortic cells was more regular,the inflammatory cell infiltration was improved,and the contents of serum inflammatory factors IL-1β and TNF-α were significantly decreased(P<0.05).The colocalization and the protein expression of Ly6G,MPO and Cit-H3 were significantly decreased in aortic tissues(P<0.01).Conclusions GZTLP can improve atherosclerosis,and its mechanism may be related to the inhibition of neutrophil extracellular trapping nets.

Objective:To analyze the effect of optical zone diameter in orthokeratology contact lenses on the efficacy of treatment.Methods:A total of 100 myopic patients (196 eyes) who wore Paragon CRT keratoplasty lenses with a diameter of 10.5 mm were retrospectively included in this study. These patients, consisting of 47 males and 53 females, were admitted to The Affiliated Hospital of Hangzhou Normal University between November 2020 and November 2022. Their ages ranged from 8 to 13 years. Their refractive errors ranged from -0.75 DS to -4.00 DS for spherical errors and from -0.25 DC to -1.50 DC for cylindrical errors. The corrected visual acuity was ≥ 0.6, and the initial axes were between 23.40 mm and 25.83 mm. The patients were grouped according to the different diameters of the optical zones of their lenses. Fifty patients (98 eyes) with an optical zone of 5.0 mm were included in the 5.0 group, and another 50 patients (98 eyes) with an optical zone of 6.0 mm were included in the 6.0 group. The general sociological and disease-related characteristics of the two groups were recorded. Logistic linear regression analysis was performed on the data with differences to obtain the therapeutic effect of different optimal zone diameters in orthokeratology contact lenses.Results:After 1 year of wearing, there was no statistically significant difference in the average non-invasive tear film break-up time between the two groups ( P > 0.05). The 5.0 group exhibited significantly lower values for the surface regularity index (0.35 ± 0.09), surface asymmetry index (0.69 ± 0.21), axial length [(0.19 ± 0.04) mm], and relative peripheral refraction [(-0.65 ± 0.20) D, (-0.84 ± 0.26) D, (-0.48 ± 0.13) D, (-0.76 ± 0.23) D, (-0.77 ± 0.21) D, (-0.56 ± 0.17) D] compared with the 6.0 group ( t = 5.94, 3.34, 4.64, 2.03, 2.07, 4.23, 2.27, 2.25, 5.55, all P < 0.05). Conversely, the uncorrected visual acuity [(0.71 ± 0.20) LogMAR] and spherical equivalent [(-0.25 ± 0.05) D] were significantly higher in the 5.0 group compared with the 6.0 group ( t = 3.31, 13.64, both P < 0.05). After 1 year of wearing, the diameter and area of the optical zone in the 5.0 group [(3.35 ± 0.28) mm and (7.50 ± 1.10) mm2] were significantly lower than those in the 6.0 group [(3.68 ± 0.38) mm and (8.50 ± 1.50) mm2, t = 6.92, 5.32, 11.16, all P < 0.05]. Furthermore, the overlapping treatment zone area to pupil area ratio (TZR) in the 5.0 group (0.53 ± 0.16) was significantly lower than that in the 6.0 group [(0.81 ± 0.19), t = 11.16, P < 0.05]. The results of logistic linear regression analysis and Pearson calculation showed that the TZR was positively correlated with the optical zone diameters of orthokeratology contact lenses ( P < 0.05). There was no significant difference in the incidence of complications between the 5.0 group [8.16% (8/98)] and the 6.0 group [12.24% (12/98), χ2 = 0.89, P > 0.05). Conclusion:The 1-year dynamic change in eye axis indicates that myopia correction is more effective and safe when the diameter of the optical zone in keratoplasty is 5.0 mm compared with when the diameter of the optical zone is 6.0 mm. Evaluating the efficacy of corneal reshaping lenses in different optical zones using statistical TZR can guarantee myopia control results. At the same time, this study demonstrates significant innovation and scientific validity, which can offer new ideas and methods for the research and application of orthokeratology contact lenses.

Background: and Purpose The relationships among interleukin (IL)-10 levels, anxiety, and cognitive status after stroke remain controversial. We aimed to determine the associations of serum IL-10 levels with poststroke anxiety (PSA) and poststroke cognitive impairment (PSCI). Methods: We recruited 350 patients with stroke, of whom only 151 completed a 1-month follow-up assessment. The Mini Mental State Examination (MMSE) and Hamilton Anxiety Scale (HAMA) were used to assess the cognitive status and anxiety, respectively. Serum IL-10 levels were measured within 24 hours of admission. Results: IL-10 levels were significantly lower in the PSA group than in the non-PSA group, and they were negatively associated with HAMA scores (r=-0.371, p<0.001). After adjusting for all potential confounders, IL-10 levels remained an independent predictor of PSA (odds ratio=0.471, 95% confidence interval=0.237–0.936, p=0.032). IL-10 levels were strongly correlated with behavior during interviews, psychic anxiety, and somatic anxiety. Patients without PSCI had higher IL-10 levels were higher in non-PSCI patients than in PSCI patients, and they were positively associated with MMSE scores in the bivariate correlation analysis (r=0.169, p=0.038), and also with memory capacity, naming ability, and copying capacity.However, IL-10 did not predict PSCI in the univariable or multivariable logistic regression. Conclusions Low IL-10 levels were associated with increased risks of PSA and PSCI at a 1-month follow-up after stroke. Serum IL-10 levels may therefore be helpful in predicting PSA.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

The many-banded krait, Bungarus multicinctus, has been recorded as the animal resource of JinQianBaiHuaShe in the Chinese Pharmacopoeia. Characterization of its venoms classified chief phyla of modern animal neurotoxins. However, the evolutionary origin and diversification of its neurotoxins as well as biosynthesis of its active compounds remain largely unknown due to the lack of its high-quality genome. Here, we present the 1.58 Gbp genome of B. multicinctus assembled into 18 chromosomes with contig/scaffold N50 of 7.53 Mbp/149.8 Mbp. Major bungarotoxin-coding genes were clustered within genome by family and found to be associated with ancient local duplications. The truncation of glycosylphosphatidylinositol anchor in the 3'-terminal of a LY6E paralog released modern three-finger toxins (3FTxs) from membrane tethering before the Colubroidea divergence. Subsequent expansion and mutations diversified and recruited these 3FTxs. After the cobra/krait divergence, the modern unit-B of β-bungarotoxin emerged with an extra cysteine residue. A subsequent point substitution in unit-A enabled the β-bungarotoxin covalent linkage. The B. multicinctus gene expression, chromatin topological organization, and histone modification characteristics were featured by transcriptome, proteome, chromatin conformation capture sequencing, and ChIP-seq. The results highlighted that venom production was under a sophisticated regulation. Our findings provide new insights into snake neurotoxin research, meanwhile will facilitate antivenom development, toxin-driven drug discovery and the quality control of JinQianBaiHuaShe.
