Medical equipment, as an important indicator of smart hospital evaluation, plays a vital role in hospital operations. To ensure the safe and efficient operation of medical equipment, a reasonable performance evaluation system is indispensable. This study introduces a platform based on Internet of Things (IoT) technology that connects medical devices and collects data, achieving standardized and structured data processing, and supporting online operational supervision. Through the Delphi method, a performance evaluation system for large medical equipment is constructed, including 4 primary indicators and 22 secondary indicators. DICOM data acquisition devices are used to achieve functions such as efficiency analysis, benefit analysis, usage evaluation, and decision-making support for medical equipment. The study is still in its early stages, and in the future, it is expected to integrate more types of equipment, achieve rational resource allocation, and significantly impact decision-making for the development of public hospitals.

Objective : To explore the role and mechanism of plasmalemma vesicle-associated protein(PLVAP) in the progression of hepatocellular carcinoma(HCC). Methods : Bioinformatic analysis, quantitative real-time PCR, Western blot and immunohistochemistry were used to analyze the expression level of PLVAP in HCC and paracancerous tissues, and its correlation with clinicopathological characteristics. Stable HCC cell lines with knockdown and overexpression of PLVAP were constructed, then cell proliferation, migration and invasion of HCC cells were examined by CCK-8, foci formation assays, wound-healing assays and Transwell assays. Western blot was used to detect the protein levels of phosphatidylinositol 3-kinase PI3K, phosphorylated phosphatidylinositol 3-kinase p-PI3K, protein kinase B AKT and phosphorylated protein kinase B p-AKT in the PI3K/AKT pathway after PLVAP knockdown and overexpression. Cell proliferation, migration and invasion were also examined in PLVAP-overexpressed cells after treatment of LY294002, an inhibitor of the PI3K/AKT pathway. Results : The expression of PLVAP was significantly higher in HCC tissues than that in adjacent non-tumor tissues(P<0.05), and was positive correlated with tumor stage, T stage, M stage, and microvascular invasion(P<0.05). Knockdown of PLVAP significantly reduced the proliferation, migration and invasion of HCC cells(P<0.001), while overexpression of PLVAP significantly increased the proliferation, migration and invasion of HCC cells(P<0.01). Western blot analysis revealed that knockdown of PLVAP decreased the protein expression levels of p-PI3K and p-AKT, overexpression of PLVAP increased the protein expression levels of p-PI3K and p-AKT, whereas the PI3K/AKT inhibitor LY294002 eliminated the effects of PLVAP on cell proliferation, migration and invasion(P<0.01). Conclusion PLVAP is highly expressed in HCC and may promote HCC progression by activating the PI3K/AKT signaling pathway.

Objective To explore the relationship between serum long non-coding RNA X-inactive specific transcript(LncRNA XIST)and microRNA-122-5p(miR-122-5p)expression and the severity of brain injury and prognosis in patients with sepsis-associated encephalopathy(SAE).Methods A total of 108 SAE patients(SAE group)and 52 patients with sepsis only(non-SAE group)admitted to the Ankang Hospital of Tradi-tional Chinese Medicine from January 2019 to December 2023 were selected as the study subjects.According to the degree of brain injury,the SAE patients were categorized into mild brain injury group[Glasgow Coma Scale(GCS)score 13-14,27 cases],moderate brain injury group(GCS score 9-12,36 cases),and severe brain injury group(GCS score 3-8,45 cases).Based on the 28-day prognosis,they were divided into death group(51 cases)and survival group(57 cases).Serum LncRNA XIST and miR-122-5p expression levels were measured using real-time quantitative PCR.The binding site of LncRNA XIST and miR-122-5p was predicted using the StarBase database,and Pearson correlation analysis was performed to evaluate the relationship be-tween serum LncRNA XIST and miR-122-5p expression in SAE patients.Multivariate unconditional Logistic regression was used to determine the association between serum LncRNA XIST,miR-122-5p expression,and prognosis in SAE patients.Receiver operating characteristic curves were used to assess the predictive efficacy of LncRNA XIST and miR-122-5p expression for SAE prognosis.Results Compared with non-SAE group,se-rum LncRNA XIST expression was increased and miR-122-5p expression was decreased in SAE group,with statistical significance(P＜0.05).There were binding sites between LncRNA XIST and miR-122-5p,and the expression of LncRNA XIST in serum of SAE patients was negatively correlated with that of miR-122-5p(P＜0.05).Serum LncRNA XIST expression in mild brain injury group,middle brain injury group and severe brain injury group was increased successively,while miR-122-5p expression was decreased successively,with statistical significance(P＜0.05).The 28-day mortality rate of SAE patients after admission was 47.22％(51/108).Compared with the survival group,the expression of serum LncRNA XIST was higher in the death group,and the expression of miR-122-5p was lower,with statistical significance(P＜0.05).High sequential organ failure assessment(SOFA)score and high expression of LncRNA XIST were independent risk factors for death in SAE patients,while high GCS scores and high miR-122-5p expression of were independent protec-tive factors(P＜0.05).The combined expression of serum LncRNA XIST and miR-122-5p predicted the death of SAE patients with greater area under the curve than that of serum LncRNA XIST and miR-122-5p a-lone(P＜0.05).Conclusion Elevated serum LncRNA XIST and decreased miR-122-5p expression levels are associated with the severity of brain injury and poor prognosis in SAE patients.The combined detection of Ln-cRNA XIST and miR-122-5p has a high predictive value for SAE prognosis.

Objective To investigate the influencing factors of disease progression and prognosis in patients with large artery atherosclerotic(LAA)cerebral infarction and analyze the value of plasma cyclin-dependent kinase 9(CDK9)level in the diagnosis and treatment of LAA cerebral infarction.Methods Patients with acute cerebral infarction admitted to the Department of Neurology of the Affili-ated Hospital of Yangzhou University between March 1,2022,and November 20,2023,were select-ed.According to the diagnostic criteria,98 patients with acute LAA(LAA group)and 33 patients with acute small artery occlusion(SAO)cerebral infarction(SAO group)were selected.Additionally,40 healthy individuals matched for age and gender from the Health Examination Center were included as control group.Based on whether the condition of LAA cerebral infarction patients progressing,they were divided into progressive cerebral infarction(PCI)group(39 patients)and the non-pro-gressive cerebral infarction(NPCI)group(59 patients).During the 3-month follow-up period,6 patients from the 98 LAA cerebral infarction patients were lost.According to the modified Rankin Scale(mRS)score at 90 days of follow-up,patients were divided into good prognosis group(mRS score≤2,59 patients)and poor prognosis group(mRS score＞2,33 patients).Fasting lipid in-dices[total cholesterol(TC),triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),glucose(GLU),glycated hemoglobin(HbA1c),and homocysteine(Hey)]were collected on the second day after admission.The National Institutes of Health Stroke Scale(NIHSS)was used to assess the degree of neurological impairment in cerebral infarction patients.Enzyme-linked immunosorbent assay(ELISA)was used to measure plasma CDK9 levels in different groups;factors influencing disease progression in patients with acute LAA cerebral infarction were explored;and receiver operating characteristic curves were plotted to evalu-ate the predictive value of CDK9 in patients with acute LAA cerebral infarction.Results Compared with the control group,the LAA group had lower HDL-C level and higher CDK9 level(P＜0.05).The LAA group had a higher proportion of diabetes history,larger infarction volume,higher NIHSS score at admission,and higher CDK9 level compared with the SAO group(P＜0.05).Binary Logistic regression analysis showed that diabetes history and plasma CDK9 levels were influencing factors for LAA cerebral infarction.There were statistically significant differences in the proportion of diabetes history,HbA1c,random GLU,and CDK9 levels between the NPCI and PCI groups(P＜0.05).Diabetes history and plasma CDK9 levels were influencing factors for disease progression in patients with acute LAA cerebral infarction.The area under the ROC curve for CDK9 in predicting acute LAA cerebral infarction was 0.854 5(95％CI,0.794 1 to 0.9148).When the CDK9 level was 602.1 ng/L,the Youden index was maximum(0.604),with a corresponding sensitivity of 0.849 and specificity of 0.755.The NIHSS score,infarction volume,and plasma CDK9 level were higher in the poor prognosis group compared with the good prognosis group(P＜0.01).Correlation analysis showed a positive correlation between mRS scores and CDK9 levels(r=0.485,P＜0.01).Conclusion Plasma CDK9 levels are significantly elevated,and is an influencing factor.It is positively correlated with disease progression and poor prognosis in acute cerebral infarction and has certain predictive value for the progression of LAA cerebral infarction.

Objective To explore the biomechanical characteristics of different types of lumbar disc herniation(LDH),and provide a theoretical basis for the clinical classification,diagnosis,and treatment of LDH.Methods A normal lumbar spine model with spinal nerves and four types of LDH models(central type,paracentral type/lateral recess type,intervertebral foramen type,extreme type)were constructed,and the biomechanical characteristics of the intervertebral discs and nerve roots in neutral posture and under six degrees of freedom conditions were analyzed.Results In neutral position,the stress of normal intervertebral disc was carger than that of the herniated intervertebral disc,and the stress ratio of annulus fibrosus and nucleus pulposus in normal model was greater than that of annulus fibrosus and nucleus pulposus in herniated models.In neutral position,the disc stress was mainly concentrated at the incisor between the protrusion and normal part,and recruitment occurred at outer edge of the disc.In flexion and extension position,the stress of the herniated intervertebral disc shifted to the right side.The maximum stress of herniated intervertebral disc appeared during right flexion,and the nerve root stress on the right side was carger than that on the left side.The stress of the herniated intervertebral disc during right rotation was slightly lower than that during right flexion,and the stress of nerve root on the right side was smaller than that on the left side.Conclusions The intervertebral disc is important in maintaining lumbar dynamic and static stability and flexibility.Different positions have an obvious effect the intervertebral disc stress.For patients with LDH,forward bending,flexion of the affected side and large extension should be avoided.Appropriate rotation of the affected side can help relieve the symptoms of nerve root compression.
