Aromatherapy refers to the method of using the aromatic components of plants in appropriate forms to act on the entire body or a specific area to prevent and treat diseases. Essential oils used in aromatherapy are hydrophobic liquids containing volatile aromatic molecules， such as limonene， linalool， linalool acetate， geraniol， and citronellol. These chemicals have been extensively studied and shown to have a variety of functions， including reducing anxiety， relieving depression， promoting sleep， and providing pain relief. Terpenoids are a class of organic molecules with relatively low lipid solubility. After being inhaled， they can pass through the nasal mucosa for transfer or penetrate the skin and enter the bloodstream upon local application. Some of these substances also have the ability to cross the blood-brain barrier， thereby exerting effects on the central nervous system. Currently， the academic community generally agrees that products such as essential oils and aromatherapy from aromatic plants have certain health benefits. However， the process of extracting a single component from it and successfully developing it into a drug still faces many challenges. Its safety and efficacy still need to be further verified through more rigorous and systematic experiments. This article systematically elaborated on the efficacy of aromatic substances， including plant extracts and natural small molecule compounds， in antibacterial and antiviral fields and the regulation of nervous system activity. As a result， a deeper understanding of aromatherapy was achieved. At the same time， the potential of these aromatic substances for drug development was thoroughly explored， providing important references and insights for possible future drug research and application.

Sacroiliac complex injuries are commonly seen in high-energy pelvic fractures. The injuries make a big difference in treatment patterns due to the diverse injury types, posing considerable challenges in formulating optimal treatment strategies, and hence are persistent clinical difficulties in orthopedic trauma. The clinical management of sacroiliac complex injuries presents several key challenges such as a non-negligible rate of missed diagnoses in associated vascular and visceral injuries, absence of standardized protocols for surgical approaches and reduction-fixation strategies across different injury patterns, and ongoing controversies regarding surgical indications and optimal timing for patients combined with concomitant lumbosacral plexus injuries. Currently, no systematic clinical guidelines are available for the diagnosis and treatment of sacroiliac complex injuries both domestically and internationally. To this end, the Pelvic and Acetabular Surgery Group, Orthopedic Branch, China International Exchange and Promotive Association for Medical and Health Care and Orthopedic Physician Branch, Chinese Medical Doctor Association organized a panel of domestic experts in the field to develop the Clinical guideline for the diagnosis and treatment of sacroiliac complex injuries ( version 2025), based on evidence-based medicine and adhering to the principles of scientific rigor, clinical applicability, and innovation. These guidelines provided 11 recommendations covering diagnosis, therapeutic principles and techniques, management protocols for lumbosacral plexus injuries, outcome evaluation, and postoperative rehabilitation pathways, etc., aiming to standardize the clinical management of sacroiliac complex injuries.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne infectious disease with a high mortality rate. Many countries worldwide have already reported local transmission, and the number of reported cases has been increasing yearly, with an ever-expanding region. No specific treatment drugs or vaccines have seriously threatened public health safety in epidemic regions. This article reviews the epidemiological characteristics, transmission routes, and control measures of SFTS.

Objective To investigate the expression levels of serum microRNA-21(miR-21)and microRNA-23a(miR-23a)in patients with Parkinson's disease(PD)and their correlations with cognitive function and inflammatory responses.Methods A total of 120 PD patients admitted to the Second Affiliated Hospital of Hebei North University between December 2019 and January 2022 were enrolled,along with 115 healthy controls from the same period.Serum miR-21 and miR-23a levels were measured by quantitative real-time PCR,while serum levels of IL-6,CRP,and TNF-α were determined by ELISA.According to Mini-Mental State Examination(MMSE)scores,PD patients were classified into a cognitive impairment group(MMSE<26,n=72)and a normal cognition group(MMSE≥26,n=48).General characteristics in clinical and biochemical indicators levels were compared between the two groups.Spearman correlation analysis was used to assess the relationships of miRNAs and MMSE scores.Multivariate logistic regression analysis was employed to identify risk factors for cognitive impairment.The predictive value of miR-21 and miR-23a was evaluated using Receiver Operating Characteristic(ROC)curve analysis.Results Serum miR-21,miR-23a,IL-6,CRP,and TNF-α levels were significantly higher in the PD group than in the control group(P<0.01).The cognitive impairment group showed higher levels of miR-21,miR-23a,and inflammatory factor than the cognitively normal group(P<0.01).Correlation analysis revealed that miR-21 and miR-23a levels were negatively correlated with MMSE scores(r=-0.472,-0.514;P<0.001)and positively correlated with IL-6,CRP,and TNF-α(P<0.001).Multivariate Logistic regression analysis revealed that high expression of miR-21,miR-23a,and a higher UPDRS score,were independent risk factors for cognitive impairment in PD patients(P<0.05).Combined detection of miR-21 and miR-23a showed higher predictive accuracy for cognitive impairment than either marker alone(P<0.05).Conclusion Serum expression levels of miR-21 and miR-23a was upregulated in PD patients,which were associated with cognitive function and inflammatory response.Combined detection shows good predictive value for cognitive impairment..

Objective To evaluate the cost-effectiveness of low-dose steroid combined with tacrolimus or cyclophosphamide in treating adult idiopathic membranous nephropathy(IMN).Methods A prospective cohort design was used to collect clinical data on IMN patients admitted to the Affiliated Hospital of Hebei University from December 2018 to April 2022.The patients were divided into the exposure group(low-dose steroid combined with tacrolimus)and control group(low-dose steroid combined with cyclophosphamide)according to the treatment regimen.Propensity score matching was employed to balance the baseline characteristics between the two groups.The total response rate was taken as the effect index,cost-effectiveness analysis was conducted by using the decision tree model,and single factor sensitivity analysis and probabilistic sensitivity analysis were used to verify the robustness of the cost-effectiveness analysis results.Results A total of 112 patients with IMN were included.After propensity score matching,46 patients were included in the exposed and control groups,respectively.The total remission rate of the exposure group was 84.78％,with the cost of 13,352.64 yuan and the cost-effectiveness ratio of 157.50.In the control group,the total remission rate was 80.43％,the cost was 8,154.18 yuan,and the cost-effectiveness ratio was 101.38.The incremental cost-effectiveness ratio of the two groups was 1 195.05,and the sensitivity analysis results were consistent with those of the cost-effectiveness analysis.Conclusion The two treatment schemes have their own advantages in the treatment of IMN.The cost-effectiveness ratio of low-dose hormone combined with tacrolimus is relatively higher,and the combination of low-dose hormone with cyclophosphamide is more economical.Both schemes have certain clinical promotion value..

Objective:To investigate the risk factors and ultrasonographic features of neonatal hepatic subcapsular haematoma (HSH).Methods:A retrospective study was conducted on five neonates diagnosed with HSH at Shaoxing Maternity and Child Health Care Hospital from June 2020 to June 2024. Clinical data, including clinical manifestations, ultrasonographic characteristics, and follow-up outcomes, and the risk factors of HSH were summarized with descriptive statistical analysis.Results:All five cases were very low/extremely low birth weight preterm infants delivered by cesarean section, with a history of birth asphyxia. Case 1 presented with hypovolemic shock postnatally and was incidentally diagnosed with HSH via abdominal ultrasound. Cases 2 and 3 were diagnosed during a routine ultrasound monitoring of the umbilical venous catheter tip position within 3 d after catheterization. Cases 4 and 5 were diagnosed by abdominal ultrasound re-examination following unsuccessful umbilical venous catheterization. Case 1 received no catheterization or external chest compression, while Cases 2, 3, and 5 received external chest compression during resuscitation. Case 2 had a history of difficult cesarean section. Cases 2 to 5 underwent umbilical venous catheterization (failed in Cases 4 and 5). Ultrasonography revealed cystic-dominant echogenicity, presenting as elongated or oval-shaped with well-defined margins, and were accompanied by varying amounts of echogenic bands and dots. Three cases had single lesions and two had multiple lesions. A total of nine hemorrhagic foci were found with four in the right posterior liver lobe, three in the right anterior lobe, and two in the left lobe. No hepatic capsule disruption was observed in any of the five cases. After immobilization, hemostasis, and supportive care, the haematoma in Case 1 completely resolved with calcification at 134 d after birth, while in the remaining four cases, the haematomas resolved completely without calcification between 17 and 62 d after birth.Conclusions:HSH may present without classical symptoms or signs. In neonates with very low/extremely low birth weight presenting hypovolemic shock, HSH should be suspected, particularly in those with perinatal trauma or a history of external chest compression during resuscitation. Abdominal ultrasound is recommended for exclusion if indicated. Ultrasound not only facilitates the diagnosis of HSH, but also enables dynamic monitoring of hematoma progression and resolution.
