ObjectiveTo analyze the clinicopathological features of patients with comorbidities of chronic hepatitis B （CHB） and steatotic liver disease （SLD）， to investigate the impact of hyperglycemia on the risk of liver fibrosis and end-stage liver diseases （ESLD）， and to provide a basis for the clinical management of such population. MethodsA total of 668 adult patients with CHB-SLD confirmed by liver biopsy in The Fifth Medical Center of Chinese PLA General Hospital from January 2011 to December 2019 were enrolled， and a retrospective cohort was established with the time of liver biopsy as the baseline and the onset of ESLD as the endpoint. All patients were followed up to March 31， 2024. Propensity score matching （PSM） was performed at a ratio of 1∶4 to balance baseline features between groups， resulting in 82 patients in the hyperglycemia group and 281 in the non-hyperglycemia group. The two groups were compared in terms of metabolic profiles， laboratory markers， and histopathological features. The Mann-Whitney U test was used for comparison of non-normally distributed quantitative data between two groups. The chi-square test or Fisher exact test was used for comparison of categorical data between two groups. A multivariate Logistic regression analysis was used to investigate the influencing factors for advanced fibrosis （AF）， and the Kaplan-Meier survival analysis and the Cox proportional-hazards regression model were used to determine the influencing factors for the development of ESLD. ResultsCompared with the non-hyperglycemia group， the hyperglycemia group had a significantly higher number of factors for metabolic disorders， a significantly higher degree of hepatic steatosis， and a significantly higher detection rate of AF （all P<0.05）. The multivariate Logistic regression analysis showed that hyperglycemia was a risk factor for AF （odds ratio = 1.753， 95% confidence interval ［CI］： 1.017　—　3.023， P=0.043）. The survival analysis showed that hyperglycemia increased the risk of ESLD （χ²=4.340， P=0.037）. The multivariate Cox regression analysis confirmed that hyperglycemia was a significant metabolic risk factor for ESLD in patients with AF （adjusted hazard ratio=3.208， 95%CI： 1.201　—　8.568， P=0.020）. ConclusionHyperglycemia can increase the risk of AF and ESLD in CHB-SLD patients. Clinical monitoring and active management should be strengthened for patients who have already developed AF and hyperglycemia.

Sucrose non-fermenting 1-related protein kinase 1 (SnRK1) is one of the highly conserved Ca²⁺ non-dependent serine/threonine protein kinases, playing a crucial role in regulating the stress responses, growth, and development of plants. SnRK1 is a three-subunit complex, and it is involved in responding to the signaling transduction induced by low-energy/low-sugar conditions. SnRK1 responds biotic and abiotic stress conditions (such as salt, drought, low/high temperatures, and diseases) through phosphorylation of key metabolic enzymes and regulatory proteins, regulation of transcription, and interactions with other proteins. Furthermore, SnRK1 is not only involved in hormone signaling pathways mediated by abscisic acid (ABA), jasmonic acid (JA) and salicylic acid (SA), but also regulates plant autophagy by inhibiting the activity of target of rapamycin (TOR). In this review, we summarized the current results of research on the discovery, structure, and classification of plant SnRK1 and its roles in the stress responses, growth, and development of plants. Furthermore, this article proposes the directions of future research. This review provides good genetic resources and a theoretical basis for the genetic improvement and biological breeding for enhancing the stress tolerance of crops.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To investigate the clinical efficacy of internal decompression based on white matter tract preservation in the treatment of malignant middle cerebral artery infarction(MMCAI).Methods A retrospective analysis was conducted on 54 patients with MMCAI.Patients were divided into a study group(n=26)and a control group(n=28)according to the surgical approach.Patients in the study group underwent preoperative fusion of CT,CTP,DWI,and DTI imaging data within a neuronavigation system.This fusion visualized the spatial relationships between the infarct core(IC),ischemic penumbra,and the corticospinal tract(CST).Subsequently,IC resection combined with decompressive craniectomy(DC)was performed while protecting the CST.Patients in the control group underwent DC alone.Key outcome measures included:changes in fractional anisotropy(FA)within the affected CST projection area at 1 month postoperatively;and 6-month postoperative mRS score,mortality,and surgical complications at 6 months postoperatively.Results At 1 month postoperatively,FA in the affected CST projection area were significantly higher in the study group than in the control group(0.092±0.013 vs.0.082±0.008,P<0.05).At the 6-month follow-up,the postoperative mRS score in the study group was significantly lower than that in the control group[2.3(1.3,4.5)vs.3.9(2.4,5.5),P<0.05]and a lower mortality rate(11.5%vs.39.3%,P<0.05)compared to the control group.However,there were no statistically significant differences between the two groups in the incidence of postoperative intracranial hemorrhage,intracranial infection,or epilepsy(P>0.05).Conclusion Internal decompression based on white matter tract protection combined with DC can reduce mortality and contribute to improving function outcomes in patients with MMCAI.

Objective To investigate the effect of neferine(Nef)on the apoptosis of nucleus pulposus cells under abnormal mechanical stretch stress and its related mechanism.Methods Rat nucleus pulposus cells were subjected to cyclic mechanical stretch stress using Flexcell-5000T tension system,and different concentrations of Nef(6.25,12.5,25 μmol/L)and acetylcysteine(NAC,2 mmol/L)were used to intervention cells.CCK-8 was used to detect cell proliferation activity;Hoechst 33258 fluorescence staining was used to observe the morphological changes of the nucleus;Flow cytometry was used to detect the cell apoptosis level;Biochemical kits were used to detect the levels of lactate dehydrogenase(LDH)in the supernatant,malondialdehyde(MDA)and superoxide dismutase(SOD)in the cells;Western blot was used to detect the expression levels of apoptosis-related proteins,including Bax,Bcl-2,apoptotic protease activating factor-1(Apaf-1),Cleaved-caspase 9,Cleaved-caspase 3,as well as extracellular matrix-associated proteins aggrecan cartilage proteoglycan(Aggrecan),collagen type Ⅱ alpha 1 chain(COL2A1),matrix metalloproteinase-3(MMP-3),and antioxidant signaling pathway proteins nuclear factor erythroid 2-related factor 2(Nrf2)and heme oxygenase 1(HO-1).DCFH-DA fluorescent probe was used to detect the level of reactive oxygen species(ROS)in cells.JC-1 staining was used to detect the level of mitochondrial membrane potential in cells.Results The apoptosis rates of nucleus pulposus cells in the control group and the 5%,10%,15%,and 20%tensile strain groups were(6.69±0.37)%,(8.24±0.33)%,(14.45±0.65)%,(30.48±0.78)%,and(43.06±1.32)%,respectively.Compared with the control group,exposure to 5%,10%,15%,and 20%mechanical stretch stress significantly increased the apoptosis rate of nucleus pulposus cells,the level of LDH in the supernatant,and the levels of ROS and MDA within the cells(P<0.05).Additionally,the levels of SOD and mitochondrial membrane potential were significantly reduced(P<0.05).Simultaneously,the protein expression levels of Bax,Apaf-1,Cleaved-caspase 9,and Cleaved-caspase 3 were markedly upregulated(P<0.05),while the expression level of Bcl-2 protein was downregulated(P<0.05).The apoptosis rates of nucleus pulposus cells in the 15%stretch group,15%stretch+6.25 μmol/L Nef,15%stretch+12.5 μmol/L Nef,and 15%stretch+25 μmol/L Nef groups were(29.74±1.03)%,(25.09±0.67)%,(20.57±0.45)%,and(16.06±0.52)%,respectively.Compared with the 15%stretch group,treatment with 6.25,12.5,and 25 μmol/L Nef significantly reduced the apoptosis rate of nucleus pulposus cells,as well as the levels of LDH in the supernatant and intracellular ROS and MDA(P<0.05);Conversely,the SOD activity and mitochondrial membrane potential were significantly enhanced(P<0.05);Additionally,the protein expression levels of Bax,Apaf-1,Cleaved-caspase 9,Cleaved-caspase 3 and MMP-3 were markedly decreased(P<0.05),while the expression level of Bcl-2,Aggrecan,COL2A1,Nrf2 and HO-1 were increased(P<0.05);Notably,the combination of 25 μmol/L Nef and NAC intervention exhibited a more pronounced effect on inhibiting apoptosis in nucleus pulposus cells induced by abnormal mechanical stretch stress(P<0.05).Conclusion Neferine can inhibit the apoptosis of nucleus pulposus cells induced by abnormal mechanical stretch stress,potentially through scavenging ROS and inhibiting mitochondrial apoptosis pathways.

Objective:To investigate the selection of treatment methods for renal tumors in pilots as well as the clinical significance of robot-assisted surgery by summarizing the process of robot-assisted surgery in the treatment of renal cell carcinoma in a pilot.Methods:The diagnosis, robot-assisted surgery and aeromedical assessment of a pilot with renal cell carcinoma were reported, and the related literature was reviewed.Results:The patient was a 44-year-old male transporter pilot, who was diagnosed with a left renal mass in the middle-lower pole of the kidney during a routine abdominal CT scan. After detailed preoperative evaluation that ruled out the possibility of distant metastasis and other surgical contraindications, the patient underwent robot-assisted laparoscopic partial nephrectomy in August 2022. The postoperative recovery went well, and renal function remained within normal limits at follow-ups. In March 2023, the pilot was concluded as qualified for flight after aeromedical assessment.Conclusions:Robot-assisted partial nephrectomy can significantly reduce surgical trauma, lower the risk of complications, and maximally preserve renal function. It is a good approach to renal tumors in pilots who can recover quickly.

Objective To investigate the effectiveness and safety of infarct core resection combined with decompressive craniectomy(DC)based on corticospinal tract(CST)protection in the treatment of massive cerebral infarction(MCI)with malignant brain edema.Methods This study retrospectively enrolled MCI patients with malignant brain edema who underwent internal decompression combined with DC at Xingtai Central Hospital from January 2021 to June 2024.The enrolled patients were divided into a control group and an experimental group base on the intracranial internal decompression method used.All patients underwent CT perfusion(CTP),CT angiography(CTA),diffusion-weighted imaging(DWI),and diffusion tensor imaging(DTI)within 24 h of admission.Preoperative imaging data was automatically processed using an artificial intelligence diagnostic system.For the experimental group,the imaging data was fused within a neuro-navigation system preoperatively to visualize the spatial relationships between the infarct core,ischemic penumbra,and CST and infarct core resection combined with DC was performed while protecting the CST through neuro-navigation.The control group underwent anterior temporal lobectomy combined with DC.Baseline and clinical data were collected from both groups,including gender,age,smoking history,alcohol consumption history,diabetes,hypertension,hyperlipidemia,hyperhomocysteinemia,atrial fibrillation history,responsible occluded vessel(internal carotid artery,middle cerebral artery),preoperative infarct volume on DWI,preoperative ischemic penumbra volume,preoperative the National Institutes of Health stroke scale(NIHSS)score,time from onset to surgery,intraoperative procedure duration,intraoperative blood loss,preoperative and 1-month postoperative fraction anisotropy(FA)values of the CST on the affected side,modified Rankin scale(mRS)score at 6 months postoperatively,and surgery-related complications within 1 month postoperatively(intracranial hemorrhage[operative site oozing,hemorrhagic transformation]and intracranial infection[surgical incision site infection,empyema,brain abscess,meningitis]).6-month follow-up after surgery were conducted through outpatient visit or telephone calls and prognosis of patients was evaluated using the mRS(with mRS of 0-3 defined as good prognosis,4-6 as poor prognosis,and 6 indicating death).The effectiveness indicators included FA value of the affected CST at 1 month postoperatively,good prognosis rate after surgery at 6 months,and 6-month mortality rate after surgery.The safety indicators included the incidence rates of surgical complications(intracranial hemorrhage and infection)within 1 month postoperatively.Based on preoperative DTI images,all patients were further divided into a CST-intact(infarct core did not invade CST,CST morphology intact or deformed/shifted)and a CST-damaged(infarct core invaded CST,CST disrupted or interrupted)subgroup for analysis.Results A total of 62patients(37 males,25 females,age 49-60 years,mean[55±4]years)were enrolled in this study.With 28 patients in the experimental group and 34 in the control group.(1)No significant differences were found in baseline or clinical data between the experimental and control groups(all P＞0.05),and the reoperative FA values of the affected CST were showed no significant differences(P=0.588).(2)The efficacy and safety metrics were evaluated.For the efficacy indices,at 1 month after the surgery,FA values of the affected CST increased significantly compared to preoperative values in both groups(0.409±0.051 vs.0.312±0.052 in the experimental group,and,0.381±0.048 vs.0.319±0.049 in control group;both P＜0.05),and the FA value was significantly higher in the experimental group than that in the control group(0.409±0.051 vs.0.381±0.048,P=0.030).At the 6-month follow-ups,the good prognosis rate was significantly higher in the experimental group than that in the control group(39.3％[11/28]vs.14.7％[5/34],P=0.028).No significant difference in the 6-month mortality rate were observed between the two groups(P=0.787).For the safety indices,no significant differences were found in the incidence rates of intracranial hemorrhage or intracranial infection within 1 month postoperatively between the two groups(both P＞0.05).(3)For further subgroup analysis,no significant differences were found in baseline or clinical data between the CST-damaged subgroup and the CST-intact subgroup in both the experimental and control groups(all P＞0.05).In CST-intact subgroup,FA values of the affected CST increased significantly at 1 month postoperatively compared to preoperatively in the study group(0.428±0.047 vs.0.342±0.045,P＜0.05)and the control group(0.401±0.051 vs.0.347±0.048,P＜0.05).While in the CST-damaged subgroup,no significant differences were found in FA value of the affected CST 1 month postoperatively compared with that preoperatively in both the experimental and control groups(bothP＞0.05).A significantly higher FA values 1 month postoperatively(0.428±0.047 vs.0.401±0.051,P=0.036)and good prognosis rate(9/12 vs.4/16,P=0.020)were observed in the CST-intact subgroup of the experimental group comparing with that of the control group,while there was no statistically significant difference in the 6-month mortality rate between the groups within the CST-intact subgroup(P=1.000).There were no statistically significant differences between the experimental group and the control group in both efficacy and safety indices within the CST-damaged subgroup(all P＞0.05).Conclusions Infarct core resection combining DC with CST protection demonstrates superior neurological functional improvement in comparison with anterior temporal lobectomy combining DC in treating MCI with malignant brain edema,particularly for patients with an intact CST before surgery(as indicated in patients'preoperative imaging results).This(infarct core resection combining DC with CST protection)approach does not increase the incidence of surgical complications.Prospective large sample controlled studies are required for further validation.

Objective:To explore the natural course of ulcerative proctitis (UP) and the risk factors associated with disease extent progression.Methods:A retrospective cohort study was conducted, including UP patients who had undergoing prospective regisration in the Department of Gastroenterology, Xijing Hospital of Digestive Diseases, Air Force Medical University between January 2000 and May 2023. All patients were ≥ 18 years old at the time of diagnosis and followed up for more than one year. The disease extent in patients at diagnosis and during follow-up was assessed according to the Montreal classification. The clinical data were compared between the progression group and the non-progression group. The cumulative proportions of disease extent progression were analyzed with the Kaplan-Meier method, and the risk factors associated with disease extent progression were analyzed with the Cox proportional hazards regression model.Results:A total of 184 UP patients were included, with a median follow-up time of 4.8 (2.8, 8.5) years. Among them, 96 were male (52.2%) and 88 were female (47.8%), with a median age at diagnosis of 39.1 (28.8, 49.7) years. At the time of diagnosis, 95 (51.6%) patients had moderate endoscopic manifestations and 64 (34.8%) had severe endoscopic manifestations, while only 25 (13.6%) patients had mild lesions. 116 patients (63.0%) experienced disease extent progression in a median time of 4.2 (1.8, 9.0) years. The cumulative proportions of disease extent progression in 1, 3, 5, and 10 years were 13.0%, 39.0%、56.7% and 78.3%, respectively. Cox regression analysis identified the use of 5-aminosalicylic acid as a protective factor against disease extent progression ( HR = 0.55, 95% CI: 0.31 ~ 0.96, P = 0.035). During follow-up, only one patient (0.5%) underwent surgery. Five patients (2.7%) were diagnosed with dysplasia, and all of these patients had experienced disease extent progression before the development of dysplasia. Conclusions:Patients with UP had a high proportion of moderate-to-severe active endoscopic findings at diagnosis, and nearly two-thirds of patients experienced disease progression during follow-up, but the rates of colectomy and neoplasia were relatively low. 5-ASA was a protective factor against disease extent progression.

Objective:To understand the knowledge, attitudes, and behaviors of residents in areas endemic for severe fever with thrombocytopenia syndrome (SFTS) and the factors influencing these aspects, to provide a scientific basis for the prevention and control of SFTS among residents in endemic areas.Methods:A multi-stage sampling method was used to select subjects for a questionnaire survey, and the collected data were analyzed and compared.Results:The awareness rate of SFTS-related knowledge among residents in the endemic areas of Qingdao was 14.38%, while the awareness rate of tick-related knowledge was 69.78%. The mean score for protective attitudes among residents in the endemic areas was 24.50±4.09, and the mean score for protective behaviors was 11.20±2.76. Among residents of different ages, occupations, and educational levels, comparisons of SFTS-related knowledge awareness rates ( χ2=293.553, P<0.001; χ2=495.216, P<0.001; χ2=677.272, P<0.001), tick-related knowledge awareness rates ( χ2=29.986, P<0.001; χ2=23.239, P=0.002; χ2=41.003, P<0.001), protective attitude scores ( H=52.094, P<0.001; H=33.446, P<0.001; H=81.715, P<0.001), and protective behavior scores ( H=52.344, P<0.001; H=28.465, P<0.001; H=67.061, P<0.001) showed statistically significant differences. Comparisons of these same factors among residents of different genders showed no statistically significant differences ( χ2=1.159, P=0.282; χ2=0.298, P=0.585; t=-0.808, P=0.419; t=-1.229, P=0.219). Comparisons of tick-related knowledge awareness rates among residents with different frequencies of outdoor work showed no statistically significant differences ( χ2=5.367, P=0.147); however, comparisons of SFTS-related knowledge awareness rates, protective attitude scores, and protective behavior scores among residents with different frequencies of outdoor work showed statistically significant differences ( χ2=117.010, P<0.001; F=4.127, P=0.006; H=56.280, P<0.001). Multivariate linear regression analysis revealed that older age, lower educational level, and less frequent outdoor work were associated with lower protective behavior scores ( t=-3.479, P<0.001; t=4.861, P<0.001; t=-7.753, P<0.001). Conclusions:Residents in the epidemic areas of SFTS have a low level of knowledge, attitude and practice. Factors influencing protective behaviors include age, occupation, educational level, and frequency of outdoor work. Farmers are a group that requires particular attention.
