Objective To explore the T/NK cell-related differentially expressed genes(T/NK-DEGs)related to the prognosis of liver cancer based on the single-cell RNA-seq data,gene expression data and clinical information in the GEO and TCGA databases,and construct the prognostic model of liver cancer.Methods The single-cell RNA-seq data and gene expression matrices of liver cancer were obtained from the GEO database.The TCGA-LIHC cohorts,including mRNA expression data,clinical information,survival infor-mation,and somatic mutation data,were obtained from the TCGA database.Based on the two databases,the prognostic model of liver cancer patients was constructed by the bioinformatics method,and the performance of the model was predicted.Results Two T/NK-DEGs,PTTG1 and UBE2C,were identified to be associated with the prognosis of liver cancer and a prognostic model of liver cancer was constructed based on them.According to the risk score,the patients were divided into the high-risk score group and low-risk score group,in which the patients with high-risk score had a worse prognosis than those with low-risk score.The areas under the receiv-er operating characteristics(ROC)curve(AUCROC)of the prognostic model at 1-year,3-year and 5-year time points were 0.685,0.647 and 0.594,respectively.The higher risk score was correlated with the advanced pathological stage(Ⅰstage,Ⅱstage,andⅢstage)and T-stage(T1,T2,and T3)(P＜0.05).The prognostic model was able to predict the proportion of tumor infiltrating immune cells,and the sensitivity of immunotherapy and chemotherapy drugs in patients with liver cancer.Conclusion The constructed prog-nostic model in this study has an important role in the prediction of individualized survival and clinical treatment response of patients with liver cancer.

Objective::This study aimed to elucidate the effect of the lipopolysaccharides/toll-like receptor 4 (LPS/TLR4) pathway on early atherosclerosis (AS) development and its associated changes in fecal metabolites, thereby providing an experimental foundation for strategies to prevent and treat early AS.Methods::Twelve Tibetan miniature pigs aged 4-5 months were divided into normal control (NC) group and AS group (6 pigs in each). The group assignment was primarily based on body weight; Secondary criteria, including glucose, lipid profiles, and inflammatory indices, were considered to ensure balanced baseline characteristics between the 2 groups (all P > 0.05). AS group received a high-fat diet for 16 weeks to establish an AS model, while the NC group received a normal diet. Subsequently, serum levels of lipids and various inflammation and oxidative stress markers were measured. Pathological changes in the aorta and colon tissue, LPS/TLR4 pathway-associated protein expressions in the aorta, as well as occludin and zonula occludens-1 in the colon were also assessed. Proton nuclear magnetic resonance spectra technology was employed for the metabolomic analysis of fecal extracts. Results::The lipid metabolism was disrupted in AS group, with significantly higher total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol levels ((12.24 ± 5.24) mmol/L vs. (1.86 ± 0.27) mmol/L, P = 0.004,6; (2.39 ± 0.50) mmol/L vs. (0.83 ± 0.07) mmol/L, P = 0.000,5; (6.94 ± 2.87) mmol/L vs. (0.77 ± 0.18) mmol/L, P = 0.003,3), as compared to that in NC group. Serum factors, including LPS, tumor necrosis factor-α, and malondialdehyde levels of AS group were significantly higher than that of NC group ((1,230.00 ± 192.70) EU/L vs. (695.70 ± 213.70) EU/L), P = 0.001,1; (424.20 ± 176.90) ng/L vs. (51.20 ± 26.61) ng/L, P = 0.023,5; (3.60 ± 0.77) nmol/mL vs. (2.62 ± 0.21) nmol/mL, P = 0.025,4). Pathological evaluations revealed prominent lipid deposition area in the aortic arch, thoracic aorta, and abdominal aorta of the AS group compared with that of the NC group (4.17% ± 2.30% vs. 0, P = 0.006,7; 6.23% ± 2.95% vs. 0, P = 0.003,6; 3.78% ± 2.18% vs. 0, P = 0.008,1). TLR4, nuclear factor kappa-B p65, and tumor necrosis factor-α expression in the aorta tissue of the AS group were upregulated, whereas occludin and zonula occludens-1 expression in colon tissues was downregulated. Additionally, metabolomics identified significant differences in 21 metabolites in the feces of the AS group compared to the NC group, with further analysis linking these differences to amino acid metabolism. Conclusions::The Tibetan miniature pig model of early AS induced by high-fat intake displayed pronounced chronic inflammation. Preliminary findings suggest that the underlying mechanisms may be associated with the LPS/TLR4 pathway and intestinal metabolic disorders.

Objective:To explore the healing effects of internal heat needle and electroacupuncture on post-stroke shoulder pain and their impacts on serum interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α).Methods:From January 2023 to March 2025, 94 patients with post-stroke shoulder pain admitted to the Affiliated Hospital of Hangzhou Normal University were included and separated into two groups according to a random number table. The 47 cases in the electroacupuncture group adopted electroacupuncture, while 47 cases in the internal heat needle group adopted internal heat needle. The pre- and post-treatment limb function, quality of life, healing effect, visual analogue scale (VAS), and serum IL-6, IL-1β, and TNF-α were compared.Results:After treatment, the Constant-Murley Shoulder Scale (CMS) score, shoulder range of motion (flexion, outward rotation, extension), Fugl-Meyer Assessment-Upper Extremity (FMA-UE) score, and Modified Barthel Index (MBI) in the internal heat acupuncture group were all better than those in the electroacupuncture group:(63.45 ± 10.31) points vs. (56.51 ± 9.15) points, (136.67 ± 32.44)° vs. (109.32 ± 25.01)°, (51.64 ± 12.84)° vs. (42.95 ± 11.72)°, (34.35 ± 10.15)° vs. (29.53 ± 9.82)°, (45.63 ± 10.25) points vs. (39.16 ± 10.43) points, (83.42 ± 16.09) points vs. (74.55 ± 15.83) points, there were statistical differences ( P<0.05). While the levels of serum IL-1β, IL-6, TNF-α, and VAS score in the internal heat needle group were decreased in the electroacupuncture group: (7.39 ± 3.68) ng/L vs. (9.28 ± 4.10) ng/L, (19.25 ± 2.12) ng/L vs. (28.50 ± 2.43) ng/L, (9.55 ± 3.54) ng/L vs. (11.17 ± 3.77) ng/L,(1.69 ± 0.45) points vs. (2.13 ± 0.56) points, there were statistical differences ( P<0.05). The therapeutic effect in the internal heat needle group was significantly higher than that in the electroacupuncture group:93.62% (44/47) vs. 78.72% (37/47), there was statistical difference ( P<0.05). Conclusions:For post-stroke shoulder pain, internal heat needle therapy has a clear healing effect than electroacupuncture, and can effectively reduce the levels of inflammatory factors such as IL-1β, IL-6, and TNF-α in serum.

Objective:To explore the impact of noise and dust exposure in the mechanical manufacturing industry on the risk of hypertension and abnormal electrocardiogram in workers, and their combined effects, in order to provide support for the prevention and treatment of occupational related diseases among workers.Methods:In January 2024, A convenience sampling method was used to study 2802 on-the-job workers who underwent occupational health check-ups from January 2023 to December 2023 at a machinery manufacturing enterprise in Baotou, Inner Mongolia. Blood pressure and electrocardiogram results were analyzed in the noise group, dust group, dust noise group and control group according to the exposure factors. For count data, the chi-square test was employed to analyze differences among groups. Additionally, a binary logistic regression model was utilized to assess the impact of dust and noise exposure on the prevalence of hypertension and electrocardiogram abnormalities.Results:The stratified analysis results showed that the differences in hypertension prevalence among the four groups were statistically significant ( P<0.001) in males, age groups >30-40 years, >40-50 years, >50 years, different exposure durations, and different enterprise sizes. For ECG abnormalities, significant differences were observed among the four groups ( P<0.001) in males, the age group >30-40 years, different enterprise sizes, and those with exposure durations ≤15 years. The trend test for hypertension prevalence across different age groups revealed that as age increased, the prevalence of hypertension showed an upward trend in the noise-exposed group, dust-exposed group, and combined dust-noise-exposed group ( χ2=10.76, 4.25, 6.60, P<0.001, 0.039, 0.010) . Binary regression model analyses revealed that the the risk of hypertension in the noise group, dust group and dust noise group was 2.63 times ( OR=2.63, 95% CI: 1.89~3.67, P<0.001) , 2.36 times ( OR=2.36, 95% CI: 1.76~3.16, P<0.001) and 2.69 times ( OR=2.69, 95% CI: 2.14~3.38, P<0.001) . Using ECG abnormalities as the dependent variable and incorporating the statistically significant variables from Table 1 as independent variables into the binary logistic regression model, the results showed no statistically significant differences in the risk of ECG abnormalities in the dust-exposed, noise-exposed, and combined dust-noise-exposed groups compared to the control group ( P> 0.05) . Conclusion:Combined exposure to dust and noise increases the risk of hypertension in workers and has a combined effect.

Preliminary findings suggest that the underlying mechanisms may be associated with the LPS/TLR4 pathway and intestinal metabolic disorders.

Objective:To explore the health education needs of patients undergoing fecal microbiota transplantation (FMT) at different stages of treatment.Methods:A qualitative research method was employed and an interview guide based on timing theory was developed. Semi-structured interviews were conducted with patients treated for colorectal conditions with FMT at Tenth People's Hospital of Tongji University from August to October 2022. Data from the interviews were analyzed using thematic analysis.Results:A total of 19 patients aged 20 to 65 were interviewed, including seven males and 12 females. A total of five main themes and 15 subthemes were identified: health education demands during the diagnosis phase (basic information about FMT; knowledge about donor screening), health education demands during the preparation phase (alleviating discomfort caused by nasoenteric tubes; interpretation of examination reports), health education demands during the execution phase (dietary guidance during FMT; exercise guidance during FMT; medication and supplementary training guidance; management of adverse reactions), health education demands during the adaptation phase (consolidating treatment effects; knowledge related to FMT capsules; post-discharge follow-up content and methods; post-discharge precautions), long-term health education demands (diverse health education tools; individualized health education approaches; alleviating psychological anxiety) .Conclusions:Patients undergoing FMT have numerous concerns, and diverse health education needs throughout the treatment process. Healthcare professionals should adopt various health education strategies to address these needs.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To identify the risk factors associated with conversion to cesarean delivery in parturients receiving epidural labor analgesia and to construct a predictive model.Methods:In this prospective cohort study, 718 parturients with a singleton fetus at 37-42 weeks of gestation age, aged 22-45 yr, of American Society of Anesthesiologists Physical Status classification Ⅱ, who received epidural labor analgesia at the Women′s Hospital affiliated to Zhejiang University School of Medicine between November 2022 and August 2023, were included and divided into 2 groups based on the final mode of delivery: cesarean delivery group (CD group) and vaginal delivery group (VD group). Data collected included maternal age, height, body mass index at labor onset, gestational age, pregnancy complications, mode of conception, parity, premature rupture of membranes, mode of labor onset and details of labor analgesia. Risk factors for conversion to cesarean delivery were analyzed using multivariate logistic regression analysis, and a prediction model was developed. The receiver operating characteristic curve was ploted, and the area under the receiver operating characteristic curve was calculated to evaluate the accuracy of the predictive model.Results:A total of 682 parturients were included in the final statistical analysis, with 103 in CD group and 579 in VD group. Multivariate logistic regression analysis showed that maternal age≥35 yr, height<160 cm, body mass index at labor onset ≥28 kg/m 2, nulliparous parturients, the use of Foley balloon catheter or dinoprostone suppositories for cervical ripening were risk factors for cesarean delivery, and cervical dilation during analgesia was a protective factor. The area under the receiver operating characteristic curve for the predictive model constructed based on the aforementioned influencing factors yielded predicting conversion to cesarean delivery due to failed vaginal trial of labor was 0.791 (95% confidence interval 0.744-0.837, P<0.001), with a sensitivity of 73.6% and a specificity of 70.9%. Conclusions:Nulliparous parturients, maternal age≥35 yr, height<160 cm, body mass index at labor onset≥28 kg/m 2, and the use of Foley balloon catheter or dinoprostone suppositories for cervical ripening are risk factors for cesarean delivery, and cervical dilation during analgesia is a protective factor. The predictive model established based on these influencing factors has high predictive performance.

Respiratory syncytial virus (RSV) is the most common respiratory pathogen in infants and young children, which can lead to severe pneumonia and even death. Early diagnosis and intervention are crucial for reducing complications and sequelae and improving prognosis. This study presents the complete diagonsis and treatment process of a typical severe RSV pneumonia patient. For high-risk children, the condition can progress rapidly after RSV infection, and may present with respiratory failure and multiple extrapulmonary complications, such as heart failure, liver and kidney function impairment, coagulation dysfunction. After active symptomatic and supportive treatment, the prognosis is generally good. RSV infection will not lead to long-lasting immunity, but as the child grows older and their immune function gradually improves, the condition of a secondary infection is generally relatively mild. Currently, there are no specific antiviral drugs or safe and effective vaccines for RSV. Long-acting monoclonal antibodies are one of the effective means to prevent RSV infection in infants and young children and have been approved for use in China.

Objective To review the diagnostic information of 3368 viral hepatitis B inpatient cases reported by some healthcare institutions in Qinghai Province in the National Notifiable Disease Report System(NNDRS)in 2021,and to analyse the consistency of their reports and influence factor.Methods The study used the typical survey method to study 3368 hospitalized cases of hepatitis B reported by 32 medical institutions in Qinghai Province in 2021 from July 2022 to April 2023.The consistency between the reported classification and the reviewed classification was evaluated by reviewing diagnostic information of the cases,combined with the Kappa consistency test,and the consistency-influencing factors were analysed in a univariate and multivariate analysis.Results The consistency between acute,chronic,and unclassified reporting classifications and review classifications was poor(Kappa＜0.40);the consistency between acute and chronic review was poor(Kappa＜0.40).The main influence factor of the consistency of review included the level of medical institution,the patient's gender,occupation,past history,and the unit of diagnosis of initial onset of illness.Provincial medical institutions reported higher consistency,and male cases and herder cases had better consistency than female cases and other occupations.Review consistency of cases with past history was better than that of cases with unclear past history.Conclusion The consistency of diagnosis and reporting of hepatitis B cases in healthcare institutions in Qinghai Province in 2021 was low,with problems of inaccurate classification and duplicate reporting.It is recommended to strengthen the training and supervision of healthcare institutions,standardise the filling of'attached card'information,and promote the hepatitis B core antibody IgM test to improve the classification and diagnosis of acute and chronic hepatitis B,so as to comprehensively improve the accuracy of the diagnosis and reporting of hepatitis B cases.
