Chronic eczema has a high prevalence in China， significantly impacting patients’ quality of life. Leveraging the unique advantages of pattern identification/syndrome differentiation and treatment， along with a holistic approach， traditional Chinese medicine （TCM）， which integrates internal and external therapies， has been widely applied in the management of chronic eczema. It has demonstrated significant efficacy and distinctive strengths in alleviating symptoms， reducing recurrence rates， maintaining disease stability， and enhancing patients’ quality of life. Oral administration of TCM（e.g. modified Longdan xiegan decoction） can improve patients’ clinical symptoms through systemic regulation. External use of TCM can directly act on the skin lesion with the help of steaming and washing， hydropathic compress， ointment and other forms. At the same time， it can effectively relieve the clinical symptoms of chronic eczema by combining with non-drug therapies such as acupuncture， moxibustion， acupoint catgut embedding， blood-letting puncture and cupping. In addition， characteristic therapies such as oral administration of TCM combined with external treatment， a combination of various external treatments and a combination of Chinese and Western medicine have also demonstrated certain advantages in regulating immune function， alleviating skin lesions， and relieving itching symptoms. These therapies cooperate with each other， creating a synergistic effect that treats both the symptoms and the root cause simultaneously. It is suggested that more high-quality， large-scale clinical research should be conducted in the future to systematically confirm the therapeutic advantages of TCM and further explore the specific molecular mechanism of action.

Objective To analyze the correlation between the poor position of pedicle screw after lumbar internal fixation and the occurrence of postoperative neurological symptoms.Methods The clinical data of patients who underwent lumbar pedicle screw surgery in our hospital from January 2017 to December 2023 were analyzed retrospectively.Record the patient's sex,age,diagnosis,surgical segment,the presence of postoperative neurological complications,the types of neurological complications.According to the postoperative CT,the screw penetration zone and grade were evaluated,and the distribution of different pedicle screw penetration types was recorded.The correlation between different types of pedicle screw penetration and postoperative neurological symptoms was analyzed.Results A total of 184 patients were included,including 80 males and 104 females.Age ranged from 18 to 82 years,with an average of 60.1±14.2 years.35 patients developed new neurological symptoms after operation.The incidence of postoperative neurological symptoms caused by pedicle medial quadrant screw penetration and lower quadrant screw penetration was higher than that of pedicle superior quadrant and lateral quadrant screw penetration.From L1 to L5,the risk of postoperative neurological symptoms caused by screw penetration in the medial quadrant of the pedicle increases gradually.When the penetration distance of pedicle medial quadrant screws in L4 and L5 segments is≥2mm,the risk of postoperative neurological symptoms is high.When the penetration distance of pedicle medial quadrant screws in L1,L2 and L3 segments is greater than 4mm,the risk of postoperative neurological symptoms is high.The distance of pedicle screw penetrating the medial quadrant of pedicle was positively correlated with the incidence of postoperative neurological symptoms(P<0.05).Conclusion The lateral and superior quadrants of the pedicle may be regarded as safety zones for lumbar pedicle screw placement.For the L1～L3 segments,screw penetration depth should not exceed 4 mm;whereas for the L4～L5 segments,the safety threshold must be strictly controlled within 2 mm.

Objective To explore the effect of different post-processing methods of total spinal CT angiography(CTA)for displaying spinal dural arteriovenous fistula(SDAVF).Methods Total spinal CTA data of 55 patients with SDAVF were retrospectively analyzed.Traditional post-processing of original CTA images(modified tissue growth boneless volume rendering[VR]and full-range axial maximum intensity projection[MIP])were performed,while the axial,sagittal and coronal MIP reconstructions,axial,sagittal and coronal VR reconstructions,as well as axial,sagittal and coronal MIP+VR reconstructions of original CTA images on lesion layers were completed,respectively.Taken digital subtraction angiography(DSA)as the gold standards,a 5-point scale was used to subjectively evaluate the effect of displaying the location,the range and feeding artery of fistula shown on CTA images based on different post-processing methods.Results No significant difference of subjective score of location nor feeding artery of fistula was found among axial MIP,VR and MIP+VR images(all P＞0.05),which were all higher than that of CTA images reconstructed using other post-processing methods(all P＜0.05).Meanwhile,no significant difference of subjective scores of the range of SDAVF was detected among sagittal MIP,VR and MIP+VR images(all P＞0.05),which were all higher than that of CTA images obtained using other post-processing methods(all P＜0.05).Conclusion The location and feeding artery of SDAVF could be observed based on axial MIP,VR and MIP+VR reconstructions of the total spinal CTA,while sagittal MIP,VR and MIP+VR reconstructions were conducive to display the range of SDAVF.Combination of multiple post-processing methods was helpful for comprehensive understanding the composition and range of SDAVF.

Establishing a one-stop diagnosis and treatment mode centered on patients and linked by diseases is of great significance for optimizing the medical process and improving the medical experience. In March 2024, a tertiary hospital integrated pediatric outpatient and emergency resources, established a pediatric diagnosis and treatment island through reasonable department settings, strengthened talent team construction, optimized diagnosis and treatment processes, and established supporting guarantee mechanisms. It was officially put into use in June of the same year, providing one-stop diagnosis and treatment services for children and achieving the goal of " not leaving the island for minor illnesses and not leaving the hospital for major illnesses". Before the operation of island (January May 2024), the complaint rate and waiting time for pediatric outpatient and emergency department were 39 cases per 100 000 patients and 15 to 30 minutes, respectively; After operation (June August 2024), the complaint rate and waiting time decreased to 17 cases per 100 000 people and 10 to 20 minutes respectively; The average monthly comprehensive income of outpatient and emergency departments increased by 33%. The pediatric diagnosis and treatment island mode could assist in the sustainable high-quality development of pediatrics in hospital, and provide references for optimizing outpatient and emergency department management in other tertiary public hospitals. In the future, we should further enrich the service content of the island and strengthen information technology construction.

Objective:This current study aims to explore the approaches for constructing a professional clinical research system within the context of research ward development, with the ultimate objective of providing valuable guidance for the establishment and development of proficient clinical research teams.Methods:Through a comprehensive case analysis, integrating the practical experiences from clinical trials conducted in the research ward of a Class-A tertiary hospital in Beijing, along with an extensive review of relevant literature and policy studies, this paper examined the current state of domestic clinical research implementation teams. Subsequently, a series of strategies were devised to build and foster professional clinical research teams and to explore corrective measures for cultivating a dynamic professional clinical research talent ecosystem.Results:The development of full-time clinical research teams in China was rather slow, and there was a lack of mature clinical trial teams training blueprints. Drawing on the practical experience accumulated during the establishment of a professional clinical research team in a leading hospital in Beijing, it was crucial to attach utmost importance to the optimal allocation of human and material resources. This required the systematic training of principal investigators, coordinating researchers, and research assistants, as well as the setting up of a comprehensive support system, an advanced scientific research team, and a quality control unit. Moreover, the standardization of operational models of both domestic and foreign research institutions, along with the implementation of corresponding support and incentive mechanisms, and the strengthening of training and continuing education frameworks were equally significant.Conclusions:During the process of assembling a full-time clinical research team, it is of utmost significance to cultivate professional principal investigators, coordinating researchers, and research assistants. Complemented by the establishment of a comprehensive support team, a scientific research team, and a quality control team, along with corresponding support and incentive mechanisms, this is crucial for constructing a professional clinical research execution team and a sustainable talent ecosystem in the research ward. Eventually, this will drive the efficient and high-quality progress of China's pharmaceutical industry.

Objective To systematically evaluate the impact of pulmonary hypertension (PH) on the prognosis of patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). Methods A computerized search was conducted in CNKI, Wanfang Data, VIP, CBM, PubMed, The Cochrane Library, EMbase, and Web of Science databases from inception to June 2023 for cohort studies on the prognostic impact of PH in severe AS patients undergoing TAVR. Two researchers independently screened the literature, extracted data, and assessed the quality of included studies. Stata 17.0 software was used for meta-analysis. Results A total of 16 cohort studies were included, all with Newcastle-Ottawa Scale scores≥7. Meta-analysis results showed that, compared with AS patients without PH, those with PH had significantly higher 1-year all-cause mortality after TAVR [OR=2.10, 95%CI (1.60, 2.75), P<0.01], 30-day all-cause mortality [OR=2.09, 95%CI (1.54, 2.83), P<0.01], and cardiovascular mortality [OR=1.49, 95%CI (1.18, 1.90), P<0.01]. The differences between the two groups in major bleeding events, stroke, myocardial infarction, pacemaker implantation, and postoperative renal failure were not statistically significant. For outcome indicators with significant heterogeneity, subgroup analyses were performed based on PH measurement methods, diagnostic criteria, and different types of PH. The results showed that most subgroup combined results were consistent with the overall findings and that heterogeneity was significantly reduced. Conclusion PH significantly increases the 30-day all-cause mortality, 1-year all-cause mortality, and cardiovascular mortality in patients with severe AS undergoing TAVR.

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.
