Objective To analyze the economic cost of self-monitoring of gestational diabetes mellitus, and provide a basis for measuring the economic burden of gestational diabetes mellitus, and to provide a reference for the formulation of intervention development and the adjustment of resource allocation. Methods The individual economic cost of self-monitoring for gestational diabetes mellitus was measured based on a decision tree model, and the total economic cost of self-monitoring for gestational diabetes mellitus in Beijing was estimated. The uncertainty of the model parameters was analyzed using one-way sensitivity analysis. Results The average individual economic cost of gestational diabetes self-monitoring was 1184 RMB, and the individual cost incurred by choosing different types of blood glucose meters ranged from 403 to 18 000 RMB. The average individual economic cost of finger-stick blood glucose monitoring was 606 RMB and the average individual economic cost of continuous glucose monitoring was 2 374 RMB. The total economic cost of gestational diabetes self-monitoring in Beijing was 23.818 0 million RMB, and the total economic cost incurred by choosing different types of blood glucose meters ranged from 0.292 5 to 9.027 9 million RMB. The proportion of the finger-stick blood glucose monitoring had the greatest impact on the robustness of the results. Conclusion Finger-stick blood glucose monitoring is still the dominant self-monitoring method and is less costly than continuous glucose monitoring. Self-monitoring of pregnant women with gestational diabetes mellitus incurs certain economic cost and causes an economic burden on society.

Soil cadmium (Cd) pollution is one of the major environmental problems globally. Ophiopogon japonicus, a multifunctional plant extensively used in traditional Chinese medicine, has demonstrated potential in environmental remediation. This study investigated the Cd accumulation pattern of O. japonicus under cadmium stress and identified the heavy metal ATPase (HMA) family members in this plant. Our results demonstrated that O. japonicus exhibited a Cd enrichment factor (EF) of 2.75, demonstrating strong potential for soil Cd pollution remediation. Nine heavy metal ATPase (HMA) members of P1B-ATPases were successfully identified from the transcriptome data of O. japonicus, with OjHMA1-OjHMA6 classified as the Zn/Co/Cd/Pb-ATPases and OjHMA7-OjHMA9 as the Cu/Ag-ATPases. The expression levels of OjHMA1, OjHMA2, OjHMA3, and OjHMA7 were significantly up-regulated under Cd stress, highlighting their crucial roles in cadmium ion absorption and transport. The topological analysis revealed that these proteins possessed characteristic transmembrane (TM) segments of the family, along with functional A, P, and N domains involved in regulating ion absorption and release. Metal ion-binding sites (M4, M5, and M6) existed on the TM segments. Based on the number of transmembrane domains and the residues at metal ion-binding sites, the plant HMA family members were categorized into three subgroups: P1B-1 ATPases, P1B-2 ATPases, and P1B-4 ATPases. Specifically, the P1B-1 ATPase subgroup included the motifs TM4(CPC), TM5(YN[X]₄P), and TM6(M[XX]SS); the P1B-2 ATPase subgroup featured the motifs TM4(CPC), TM5(K), and TM6(DKTGT); the P1B-4 ATPase subgroup contained the motifs TM4(SPC) and TM6(HE[X]GT), all of which were critical for protein functions. Molecular docking results revealed the importance of conserved sequences such as CPC/SPC, DKTGT, and HE[X]GT in metal ion coordination and stabilization. These findings provide potential molecular targets for enhancing Cd uptake and tolerance of O. japonicus by genetic engineering and lay a theoretical foundation for developing new cultivars with high Cd accumulation capacity.

Objective:To analyze the status quo of type D personality, intolerance of uncertainty and family support in first-episode stroke patients, and to explore the mediating role of family support between type D personality and intolerance of uncertainty in first-episode stroke patients, in order to provide reference for formulating relevant clinical intervention measures to promote the physical and mental health of first-episode stroke patients.Methods:This study was a cross-sectional investigation. A total of 300 patients with acute first-episode stroke who met the inclusion and exclusion criteria in the Department of Neurology of the General Hospital of Ningxia Medical University and the First People′s Hospital of Yinchuan from May 2023 to September 2023 were selected as the study objects by convenience sampling method. The general data questionnaire, Type D personality Scale-14, Family Caring Index Scale and the Intolerance of Uncertainty Scale were used to investigate them. Pearson correlation analysis was used to test the correlation between variables, and SPSS plug-in PROCESS 3.5 was used to test the mediation effect.Results:Finally, 300 questionnaires were effectively collected, including 228 males and 72 females. Patients aged ≥ 60 years old were the majority, accounting for 49.3% (148/300). The detection rate of type D personality in the first stroke patients was 37.3% (112/300), and the total score of Type D personality inventory, family support and intolerance of uncertainty of type D personality in the first stroke patients were (22.16 ± 9.95), (6.40 ± 2.23), (27.82 ± 7.93) points. The correlation analysis results showed that the intolerance of uncertainty of type D personality in the first stroke patients was positively correlated with type D personality scores ( r=0.675, P<0.001). There was a negative correlation with family support score ( r=-0.644, P<0.001). The results of mediating effect analysis showed that family support played a partial mediating role in the relationship between type D personality and intolerability of uncertainty in first-stroke patients, and the mediating effect accounted for 34.94% of the total effect. Conclusions:The mediating role of family support between type D personality and intolerability of uncertainty in first-stroke patients is established. In the future, the level of family support of patients can be continuously improved to reduce their intolerability of uncertainty, so as to promote the physical and mental health of patients and improve their quality of life.

Objective To observe the role of the renin-angiotensin system in myocardial injury induced by experi-mental vascular dementia.Methods Eighteen adult male rats were categorized into a normal group,sham group,and modified 2-vessel occlusion group(model).To assess the myocardial injury caused by experimental vascular dementia,immunostaining was conducted to evaluate the interstitial collagen fraction and myocyte cross-sectional ar-ea.The concentrations of angiotensin Ⅱ(Ang Ⅱ)and angiotensin 1-7(Ang1-7)in the serum,as well as the ex-pression levels of angiotensin converting enzyme(ACE),angiotensin converting enzyme 2(ACE2),Ang Ⅱ,Ang1-7,angiotensin type 1(AT1)receptor,and Mas receptor in the myocardium,were assessed.Results Modified 2-vessel occlusion led to pronounced cognitive dysfunction(P＜0.01)and myocardial injury(P＜0.000 1)when compared to the sham and normal groups.Additionally,modified 2-vessel occlusion induced significant upregulation of the ACE/Ang Ⅱ/AT1 receptor axis(P＜0.01)and downregulation of the ACE2/Ang1-7/Mas axis(P＜0.05)of the renin-angiotensin system in the myocardium.Conclusion Myocardial injury in rats with experimental vascu-lar dementia may be related to dysregulation of the renin-angiotensin system.

Objective To observe the effect of intelligent flexible ankle stretching training on lower extremity spasm in patients with spinal cord injury. Methods From June,2021 to May,2024,28 patients with spinal cord injury were randomly divided into control group(n=14)and experimental group(n=14).Both groups received conventional rehabilitation treatment.On this ba-sis,the control group received manual extension treatment,and the experimental group received intelligent flexi-ble ankle stretching system training,for eight weeks.The modified Ashworth Scale(MAS),ankle dorsiflexion an-gle,Clinical Spasticity Index(CSI),max root mean square(RMSmax)of surface electromyography of gastrocne-mius medial head and vibration perception threshold(VPT)of great toe were compared. Results After treatment,MAS(χ2=10.378,P=0.035),ankle dorsiflexion angle(Z=-3.306,P<0.001),CSI(t=4.101,P=0.001)and RMSmax of gastrocnemius medial head(Z=-3.296,P<0.001)improved in the experimental group,while MAS(χ2=11.418,P=0.022),ankle dorsiflexion angle(Z=-1.986,P=0.047)and RMSmax of gas-trocnemius medial head(Z=-2.297,P=0.021)were better in the experimental group than in the control group.Although VPT was improved after treatment,no significant difference was found within and beteen groups(P>0.05). Conclusion The intelligent flexible ankle stretching training could improve the lower limb muscle spasticity in patients with spinal cord injury,and may be benefit for foot proprioception.

Objective To investigate the diagnostic value and clinical significance of hypersensitive C-reactive protein(hs-CRP),procalcitonin(PCT)combined with interleukin-6(IL-6)in children with severe hand-foot-mouth disease.Methods A total of 62 children hospitalized in our hospital from January 2022 to December 2022 were collected as research objects.According to the severity of infection,they were divided into observation group(severe infection group)with 29 cases and control group(mild infection group)with 33 cases.The differences of general data,total leukocyte count,neutrophil count,lymphocyte count,platelet count,hs-CRP,PCT,IL-6 and creatine kinase isoenzyme(CK-MB)between the two groups and their clinical applications were analyzed and compared.Results The total white blood cell count,neutrophil count,lymphocyte count,hs-CRP,PCT and IL-6 in the observation group were higher than those in the control group,and the difference has statistically significant.Receiver operator characteristic(ROC)curve analysis of hs-CRP predicted the sensitivity and specificity of severe infection of hand-foot-mouth disease were 79.3%and 93.9%(95%CI:0.852-10.985,P<0.05);The sensitivity and specificity of PCT were 93.1%and 84.8%(95%CI:0.907-1,P<0.05);The sensitivity and specificity of IL-6 were 96.6%and 87.9%(95%CI:0.945-1,P<0.05).Conclusions In hand-foot-mouth classification,PCT and IL-6 are highly sensitive.Although hs-CRP is less sensitive than the former,its specificity is higher than the former.Therefore,the combination of hs-CRP,PCT and IL-6 has higher value for hand-foot-mouth classification.

Objective To explore the abnormal changes of resting state functional connectivity of pain networks in patients with cervical discogenic pain(CDP).Methods The resting-state functional magnetic resonance imaging(rs-fMRI)data of 40 patients with CDP and 40 age-and gender-matched healthy controls(HC)were collected.The seed of posterior insula(PI)was used to define the pain network,and seed-based whole-brain functional connectivity analyses were performed to explore the difference of functional connectivity between CDP patients and HC,the associations between functional connectivity and clinical measures were analyzed.Results The functional connectivity between bilateral PI and bilateral thalamus(THA)was increased,and the functional connectivity between left PI and middle cingulate cortex(MCC),left postcentral gyrus(PoCG)and MCC were decreased in CDP patients.Moreover,the func-tional connectivity between right PI and left THA was positively correlated with visual analogue scale(VAS),and the functional connectivity between left PoCG and MCC was negatively correlated with VAS.Conclusion Functional connectivity abnormalities exist in pain network resting state of CDP patients,which may provide an imaging basis for revealing the neuropathological mechanism of pain in CDP patients.

Objective:To explore whether transjugular intrahepatic portosystemic shunt (TIPS) can improve the prognosis of esophagogastric variceal bleeding (EGVB) combined with sarcopenia in cirrhotic patients.Methods:A retrospective cohort study was performed. A total of 464 cases with cirrhotic EGVB who received standard or TIPS treatment between January 2017 and December 2019 were selected. Regular follow-up was performed for the long-term after treatment. The primary outcome was transplantation-free survival. The secondary endpoints were rebleeding and overt hepatic encephalopathy (OHE). The obtained data were statistically analyzed. The t-test and Wilcoxon rank-sum test were used to compare continuous variables between groups. The χ2 test, or Fisher's exact probability test, was used to compare categorical variables between groups. Results:The age of the included patients was 55.27±13.86 years, and 286 cases were male. There were 203 cases of combined sarcopenia and 261 cases of non-combined sarcopenia. The median follow-up period was 43 months. The two groups had no statistically significant difference in follow-up time. There was no statistically significant difference in transplant-free survival between the TIPS group and the standard treatment group in the overall cohort ( HR=1.31, 95% CI: 0.97-1.78, P=0.08). The TIPS patient group with cirrhosis combined with sarcopenia had longer transplant-free survival (median survival: 47.76 vs. 52.45, χ2=4.09; HR=1.55, 95 CI: 1.01~2.38, P=0.04). There was no statistically significant difference in transplant-free survival between the two kinds of treatments for patients without sarcopenia ( HR=1.22, 95% CI: 0.78~1.88, P=0.39). Rebleeding time was prolonged in TIPS patients with or without sarcopenia combination (patients without combined sarcopenia: median rebleeding time: 39.48 vs. 53.61, χ2=18.68; R=2.47, 95 CI: 1.67~3.65, P<0.01; patients with sarcopenia: median rebleeding time: 39.91 vs. 50.68, χ2=12.36; HR=2.20, 95 CI: 1.42~3.40, P<0.01). TIPS patients had an increased 1-year OHE incidence rate compared to the standard treatment group (sarcopenia patients: 6.93% vs. 16.67%, χ2=3.87, P=0.049; patients without sarcopenia combination: 2.19% vs. 9.68%, χ2=8.85, P=0.01). There was no statistically significant difference in the long-term OHE incidence rate between the two kinds of treatment groups ( P>0.05). Conclusion:TIPS can significantly prolong transplant-free survival compared to standard treatment as a secondary prevention of EGVB concomitant with sarcopenia in patients with cirrhosis. However, its advantage is not prominent for patients with cirrhosis in EGVB without sarcopenia.

Objective:To compare the diagnostic performance of multiparametric magnetic resonance imaging (mpMRI) and prostate-specific membrane antigen (PSMA) PET/CT in detecting pelvic lymph node metastasis in prostate cancer.Methods:This is a retrospective case series study. A retrospective analysis was conducted on the data of 115 prostate cancer patients who underwent both mpMRI and PSMA PET/CT before undergoing radical prostatectomy and extended pelvic lymph node dissection at the Department of Urology, Xiangya Hospital, Central South University, between March 2020 and September 2023. The age ( M(IQR)) was 67(10) years (range: 45 to 84 years), and the body mass index was 24(4) kg/m 2 (range: 18 to 30 kg/m 2). Pathological and imaging data were obtained from the patients. Lymph node pathology results were used as the gold standard to evaluate the diagnostic performance of mpMRI and PSMA PET/CT for detecting pelvic lymph node metastasis in PCa through diagnostic evaluation tests. Comparisons between groups were performed using independent samples t-test, Mann-Whitney U test, or χ2 test. Results:The positive rate for detecting pelvic lymph node metastasis was 18.3% (21/115) with mpMRI and 25.2% (29/115) with PSMA PET/CT. The pathological positive rate for lymph nodes was 28.7% (33/115). In patient-based analysis, the diagnostic sensitivity of PSMA PET/CT was significantly higher than that of mpMRI (63.6% vs. 30.3%, χ2=7.36, P=0.007). In lesion-based analysis, both the sensitivity and positive predictive value of PSMA PET/CT were significantly higher than those of mpMRI (sensitivity: 68.0% vs. 21.6%, χ2=42.20, P<0.01; positive predictive value: 50.0% vs. 23.1%, χ2=7.54, P=0.006). Conclusions:PSMA PET/CT and mpMRI both demonstrates good specificity in predicting pelvic lymph node metastasis in prostate cancer. However, PSMA PET/CT is significantly superior to mpMRI in terms of sensitivity and the detection rate of pathologically positive lymph nodes.
