Narcotic plants are strictly regulated worldwide due to their ability to extract drug alkaloids and drug precursor components. Besides the three traditional core species, cannabis, opium poppy, and coca, the misuse of psychoactive plants with addictive properties has become increasingly prevalent globally in recent years, and the establishment of accurate identification methods for such plants has become an urgent need in the field of narcotics control. Within existing identification frameworks, the conventional morphological and chemical analysis methods, despite their long-term application, have demonstrated considerable limitations. In contrast, DNA-based molecular identification techniques have achieved significant advancement in recent years due to their high specificity and stability. This review comprehensively examines current DNA-based identification approaches for narcotic plants through three key dimensions: DNA molecular marker technology, DNA barcoding technology, and emerging molecular biological techniques, and elaborates on the principles, technical characteristics, application scenarios, and research progress of each technology, providing some reference for the scientific selection of DNA identification strategies for narcotic plants in different specific scenarios.

Apical microsurgery is accurate and minimally invasive, produces few complications, and has a success rate of more than 90%. However, due to the lack of awareness and understanding of apical microsurgery by dental general practitioners and even endodontists, many clinical problems remain to be overcome. The consensus has gathered well-known domestic experts to hold a series of special discussions and reached the consensus. This document specifies the indications, contraindications, preoperative preparations, operational procedures, complication prevention measures, and efficacy evaluation of apical microsurgery and is applicable to dentists who perform apical microsurgery after systematic training.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.

Bipolar disorder (BD) affects 1% of the global population. BD is a group of chronic psychiatric disorders characterized by recurrent manic or hypomanic episodes that may alternate with depressive episodes. Given the current diagnostic modalities, accurately diagnosing BD, particularly distinguishing it from unipolar depression (UD), is challenging. Biomarkers have emerged as potent instruments for establishing objective diagnostic criteria for BD, and their identification, which reflects the pathophysiological processes of BD, can facilitate the precise diagnosis of the disorder. In this review, the search terms "BD" and "diagnosis" or "biomarker" were used as the key search syntax. In total, 110 studies were included. This review systematically examines the research in the field and summarizes current studies on biomarkers of BD in omics and neuroimaging. We hope that this review will benefit research aimed at establishing objective diagnostic criteria for BD and developing novel therapeutic interventions.

Objective:To investigate the application and management status of midline catheters in 1 954 hospitals, providing a basis for optimizing intravenous therapy nursing practices.Methods:This study used convenience sampling. From November 2023, members of the Intravenous Therapy Nursing Professional Committee of the Chinese Nursing Association selected 1 954 hospitals across various regions of China. Questionnaire on the Current Status of Intravenous Therapy in Hospitals at All Levels designed by the committee, based on literature review and expert discussions, was used to collect data on intravenous therapy practices in different hospitals. Multiple response analysis was applied to analysis the results of multiple-choice questions, where response numbers represent the total number of times each option was selected, and response rates refer to the proportion of selected times for each option out of all selected responses.Results:A total of 1 954 questionnaires were distributed across 31 provinces/municipalities/autonomous regions, and 1 954 valid questionnaires were returned, achieving a 100.0% valid response rate. Among the hospitals surveyed, 844 used midline catheters. Regarding the skin disinfection area for midline catheter insertion, the highest response rate was for a range of>20 cm. The highest response rate for catheter insertion techniques was ultrasound-guided Seldinger puncture. The highest response rate for maintenance interval was once a week. The top three responses for nursing documentation related to midline catheters were informed consent for intubation, puncture record, and maintenance record. The most frequently chosen processes were catheter placement, maintenance, removal, and complication management processes. The qualification for midline catheter intravenous therapy specialist nurses was mostly obtained through specialized nurse training, followed by hospital-based and department-based training.Conclusions:The application of midline catheters has rapidly developed but still reveals some deficiencies, including the choice of puncture tools, infection control, and catheter maintenance. It is recommended to improve nursing documentation and management processes related to midline catheters, establish industry standards suitable for China's national conditions, and strengthen and standardize the specialized training of intravenous therapy nurses to promote the healthy development of intravenous therapy in China.

Objective:To evaluate the effectiveness of nursing interventions based on self-efficacy theory in patients with primary glaucoma undergoing scleral flap suture trabeculectomy.Methods:A convenience sampling method was used to select 350 patients with primary glaucoma undergoing scleral flap suture trabeculectomy admitted to the Department of Ophthalmology at the First Affiliated Hospital of Zhengzhou University from October 2021 to December 2023. Participants were randomly divided into a control group ( n=175) and an intervention group ( n=175) using a random number table. The control group received routine nursing care, while the intervention group received nursing interventions based on self-efficacy theory for a duration of three months. Visual status (visual acuity and intraocular pressure), self-management behaviors, and vision-related quality of life were compared between the two groups before and after the intervention. Results:After the intervention, the intervention group had significantly better visual acuity and lower intraocular pressure compared to the control group (both P<0.05). Scores across all dimensions of the Glaucoma Self-Management Questionnaire were significantly higher in the intervention group than in the control group, while scores on the 25-item National Eye Institute Visual Function Questionnaire were significantly lower (both P<0.05) . Conclusions:Nursing interventions based on self-efficacy theory are effective in improving visual acuity and reducing intraocular pressure, enhancing self-management behaviors, and improving vision-related quality of life in patients with primary glaucoma undergoing scleral flap suture trabeculectomy.

Objective To identify potential ergonomic risk factors of works and quickly assess their risks of developing work-related musculoskeletal disorders (WMSDs) in the medical staff. Methods A total of 188 medical staff were selected as the research objects using a two-stage random sampling method. The method for the identification of musculoskeletal stress factors (PLIBEL) was used to analyze the adverse ergonomic factors in the work process, and the rapid entire body assessment (REBA) was used to quickly assess the whole-body posture load. Results The PLIBEL assessment results showed that various adverse ergonomic factors affected different parts of the body during the work process of medical staff. Specifically, 18 adverse ergonomic factors were identified in the neck, shoulders, and upper back, while 10 adverse ergonomic factors were identified in the elbow, forearm, hand, and lower back. Rehabilitation therapists and nurses engaged in patient handling in general wards and medication preparation and blood collection were exposed to ≥35 adverse ergonomic factors. The REBA assessment showed that the REBA score was 3-12 points for medical staff during their work process. Rehabilitation therapists were classified as having an extremely high ergonomic risk. High-risk occupations included ward housekeeping nurses, surgery assistant nurses, operating-room instrument nurses, and surgeons. Medium-risk occupations included general ward nurses (medication preparation and blood collection, venipuncture/infusion, and patient handling), intensive care unit (ICU) nurses, internal medicine residents, and dentists. Low-risk occupations included administrative front-desk nurses, outpatient internal medicine physicians, and technicians/physicians in ultrasonography, laboratory medicine, physical examination, and occupational health departments. Conclusion Adverse ergonomic factors of medical staff predominantly affect the neck, shoulders, upper back, elbows, forearms, hands, and the lower back during the work process. Rehabilitation therapists, ward housekeeping nurses, ICU nurses, operating-room instrument nurses, and surgeons are high-risk groups for WMSDs. Attention should be paid to the management and control of adverse ergonomic factors for medical staff to prevent the occurrence of WMSDs.

Thyroid diseases are clinically prevalent endocrine and metabolic disorders, including various types such as Hashimoto's thyroiditis and thyroid nodules. Their pathogenesis is complex and influenced by numerous factors, potentially involving genetic factors, environmental factors, and immune dysfunction. With the continuous advancement of modern traditional Chinese medicine (TCM), TCM has established a unique theoretical system in the prevention and treatment of thyroid diseases, with increasingly rich clinical practical experience. This article reviews the recent application of TCM health status analysis, monitoring, early warning, and prevention in the field of thyroid diseases, aiming to provide useful references for in-depth study in this field.

Objective:To investigate the efficacy and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for the treatment of BCR::ABL-negative chronic neutrophilic leukemia (CNL) and MDS/MPN with neutrophilia.Methods:This study retrospectively analyzed 12 cases of CNL and MDS/MPN with neutrophilia that underwent allo-HSCT from March 2017 to June 2024, comprising 7 males and 5 females with a median age of 48 ( IQR: 28, 59) years. The 2-year overall survival (OS), disease-free survival (DFS), cumulative incidence of relapse (CIR), and transplantation-related mortality (TRM) rates were analyzed. Complications were also assessed. Results:Of the 12 patients, 6 received matched sibling HSCT and 6 received haploidentical HSCT. All patients had successful engraftment, and the median times of neutrophil and platelet engraftment were 17 ( IQR: 11, 24) days and 15 ( IQR: 9, 28) days, respectively. Grade Ⅱ–Ⅳ acute graft versus host disease (GVHD) and chronic GVHD occurred in 2 and 4 cases, respectively. The 2-year OS, DFS, CIR, and TRM rates were (65.6 ± 16.4) %, (41.7 ± 16.6) %, (47.2 ±18.2) %, and (11.1 ± 11.4) %, respectively, after a median follow-up time of 637 ( IQR: 330, 943) days. One patient died from treatment-related complications due to respiratory failure caused by coronavirus disease 2019. Two patients died due to relapse. Conclusion:Allo-HSCT can be applied as a safe and effective approach to treat CNL and MDS/MPN with neutrophilia.
