Objective To use multiple model integration to predict the potential distribution of suitable areas for Hedysari Radix in China and the main environmental factors affecting its distribution.Methods Based on 119 geographical distribution points obtained from species distribution databases,and incorporating 19 bioclimatic and topographic factors,a species distribution model was constructed using the Biomod2 software package 3.5-1 version ensemble modeling platform,integrating six algorithms including generalized linear model,gradient boosting machine,random forest,and others.Geographic information system spatial analysis methods were used to quantitatively assess the distribution characteristics of suitable habitats of Hedysari Radix under current climate conditions and under future climate scenarios,while identifying the primary environmental drivers of its distribution.Results The ensemble model showed significantly superior predictive performance.TSS value and AUC value were 0.924 and 0.992,respectively.Key environmental factors significantly influencing the distribution of Hedysari Radix included slope,aspect,daily average temperature difference,isothermity,seasonal variation coefficient of temperature,lowest temperature in the coldest month,annual precipitation,driest month precipitation,and seasonal variation coefficient of precipitation.Under current climate conditions,suitable habitats for Hedysari Radix were primarily concentrated in the regions of Longnan and Dingxi in Gansu Province,covering an area of approximately 26.17×104 km2.Under future climate scenarios,suitable habitats will gradually shift toward the northwest into lower temperature zones,with a significant reduction in area.Conclusion The habitat suitability model developed in this study provides a basis for the conservation and sustainable utilization of Hedysari Radix genetic resources,while also offering a methodological reference for ecological adaptability studies of medicinal plants.

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.

AIM: To analyze the influencing factors of capsular constriction syndrome(CCS)in cataract patients after phacoemulsification(Phaco)combined with intraocular lens(IOL)implantation.METHODS: Retrospective study. The data of 2 900 cataract patients(2 900 eyes)in our hospital's information system from January 2021 to January 2024 were collected. All patients were treated with Phaco combined with IOL implantation, and the incidence of CCS within 30 wk after surgery was recorded. Patients were categorized into CCS(116 cases, 116 eyes)and N-CCS group(2 784 cases, 2 784 eyes)based on the occurrence of CCS. The basic data of the two groups were compared, and the influencing factors of CCS within 30 wk after Phaco combined with IOL implantation in cataract patients were analyzed by multivariate Logistic regression.RESULTS: Among 2 900 patients(2 900 eyes)included, 116 cataract patients(116 eyes)developed CCS within 30 wk after Phaco combined with IOL implantation, with an incidence rate of 4.00%. The single factor and multi-factor Logistic regression analysis showed that the complicated diabetes, high myopia, complicated glaucoma, and axial length(AL)>30 mm were the risk factors for the occurrence of CCS after Phaco IOL implantation in cataract patients(all P<0.05).CONCLUSION: Attention should be paid to cataract patients with diabetes, high myopia, glaucoma and AL>30 mm, which will increase the risk of CCS within 30 wk after Phaco combined with IOL implantation in cataract patients.

OBJECTIVE:There are many kinds of biological scaffolds used for pulp revascularization in clinical practice,and the difference of efficacy between different scaffolds is controversial.The efficacy of nine kinds of biological scaffolds in endodontic revascularization was evaluated by Bayesian network meta-analysis.METHODS:The computer was used to search the literature in CNKI,VIP,WanFang,China Biomedical Literature Service System,PubMed,Cochrane Library,Web of Science,Embase,and Scopus databases.Randomized controlled trials of different biological scaffolds for the treatment of pulp revascularization in young permanent teeth meeting inclusion criteria were collected from each database up to April 1,2024.Two researchers sifted through the literature,data collection,sorting and extraction were completed independently,and the quality of the included literature was assessed for risk of bias.A network meta-analysis was performed using BUGSnet1.1.1 package of R4.2.0 software.RESULTS:A total of 22 studies with 926 affected teeth and 9 different interventions were included in this study.The results of network meta-analysis showed that:(1)Clinical success rate(primary goal):platelet-rich fibrin was superior to blood clot[OR=1.45,95％CI(0.32,2.69)],and the top three ranking results were:concentrated growth factor(82.77％)＞platelet-rich fibrin(75.38％)＞modified platelet-rich fibrin(62.39％).(2)Increased root length(secondary goal):There was no difference among the 7 biological scaffolds at 1-6 months of follow-up(P＞0.05),the top 3 ranking results of rank probability were:concentrated growth factor(86.25％)＞platelet-rich plasma(53.76％)＞platelet-rich fibrin(51.11％).When followed up for＞6 months and＜12 months,concentrated growth factor was superior to blood clot[MD=9.59,95％CI(0.52,18.40)],the top 3 ranking results of rank probability were:concentrated growth factor(92.42％)＞platelet-rich plasma(56.03％)＞platelet-rich fibrin(55.76％).When followed up for more than 12 months,concentrated growth factor was superior to modified platelet-rich fibrin[MD=11.01,95％CI(0.02,22.72)],the top 3 ranking results of rank probability were:concentrated growth factor(86.95％)＞platelet-rich fibrin(68.61％)＞blood clot combined with collagen(52.5％).(3)Increased root wall thickness(secondary goal):at 1-6 months of follow-up,platelet-rich fibrin was superior to blood clot[MD=11.37,95％CI(4.74,17.71)],the top 3 ranking results of rank probability were:platelet-rich fibrin(93.66％)＞concentrated growth factor(63.11％)＞modified platelet-rich fibrin(50.48％).At＞6 months and＜12 months of follow-up,there was no difference among the 6 biological scaffolds(P＞0.05),the top 3 ranking results of rank probability were:modified platelet-rich fibrin(73.63％)＞platelet-rich fibrin(62.36％)＞concentrated growth factor(56.25％).When followed up for more than 12 months,there was no difference among the 9 biological scaffolds(P＞0.05),and the top 3 ranking results of rank probability were:blood clot combined with collagen(81.9％)＞platelet-rich plasma(62.67％)＞modified platelet-rich fibrin(59.49％).(4)Pulp vitality(third-level goal):there was no difference among the 6 biological scaffolds(P＞0.05),and the top 3 ranking results of rank probability were:blood clot combined with collagen(84.22％)＞concentrated growth factor(67.71％)＞platelet-rich fibrin(48.79％).CONCLUSION:Existing evidence shows that the clinical success rate of different scaffolds is higher in pulp revascularization,among which platelet-rich fibrin is better than blood clots.In terms of comprehensive comparison of root length and root wall thickness increase,concentrated growth factor performs best in the follow-up period of 1-6 months and＞6 months and＜12 months,while blood clot combined with collagen performs best after follow-up of more than 12 months;concentrated growth factor performs outstandingly in all levels of goals,and may be more conducive to the continued development of the tooth root than other scaffolds,and has great potential in pulp regeneration treatment.Limited by the quality and quantity of literature,the above conclusions still need to be verified by more high-quality studies.

Objective:To observe any effect of supplementing rehabilitation training with low-frequency repetitive transcranial magnetic stimulation (rTMS) on the abnormal spine posture of Parkinson′s disease (PD) patients.Methods:A total 40 PD patients with Pisa syndrome (PS) were randomly divided into an observation group and a control group, each of 20. Both groups received conventional drug therapy and rehabilitation training (including myodynamia training and balance function training), while the observation group was additionally provided with low-frequency rTMS of the primary motor cortical area (M1) on the convex side of the scoliosis. Before the treatment and after 2 and 3 weeks, the scoliosis angle was measured, and motor functioning and balance were evaluated using the timed up and go test (TUGT) and the Berg balance scale (BBS). The subjects′ mental state was quantified using the exercise self-efficacy (ESE) scale, and the modified Barthel Index (MBI) was used to quantify their ability in the activities of daily life.Results:After the treatment, significant improvement was observed in the average scoliosis angles, TUGT, BBS, ESE and MBI scores of both groups compared to the pre-treatment levels. In the control group, all of the indicators had returned to their pre-treatment levels 3 weeks after treatment, but in the observation group they remained significantly improved.Conclusions:Low-frequency rTMS combined with rehabilitation training can significantly reduce the scoliosis angle of PD patients, improve their motor functioning and balance, increase their exercise confidence and improve their ability in the activities of daily living over the long term. The combination is worth applying and promoting in clinical practice.

Objective:To observe any effect of combining transcranial magnetic stimulation (rTMS) with aerobic exercise on the cognitive functioning of early stage Parkinson′s disease (PD) patients.Methods:A total of 120 PD patients in the early stage were randomly divided into an observation group and a control group, each of 60. Both groups received conventional drug treatment and moderate-intensity aerobic exercise training, while the observation group was additionally provided with high-frequency rTMS treatment. Before and after 3 months of the treatments, everyone′s cognitive and motor functioning was evaluated using the Montreal Cognitive Assessment Scale (MoCA) and the third part of the Unified Parkinson′s Disease Rating Scale (UPDRS-Ⅲ), respectively. Negative emotions were evaluated using the Hamilton Anxiety Scale (HAMA) and the Hamilton Depression Scale (HAMD). Auditory event-related potentials were also detected, and the latency and amplitude of P300 were analyzed.Results:The average MoCA, UPDRS-Ⅲ, HAMA and HAMD scores, as well as the amplitude and latency of P300 had improved significantly in both groups after the treatment. At that point the observation group′s performance was significantly better than that of the control group in terms of the MoCA′s visuospatial and executive function, attention and delayed recall indicators, and also total score. The observation group′s average HAMA score (10.55±3.11), HAMD score (9.78±4.10), the P300 amplitude [(11.29±2.21)μV] and latency [(384.75±48.26)ms] were also significantly better. The UPDRS-Ⅲ scores were negatively correlated with the visuospatial and executive function scores of the MoCA scale in the observation group before and after treatment, while the average HAMA score was negatively correlated with the attention and delayed recall scores.Conclusions:Supplementing aerobic exercise with rTMS can significantly improve the cognition and motor functioning of early stage PD patients. The combination is more effective than aerobic exercise alone. Such combined therapy is worthy of popularization and clinical application.

Objective To construct a database for molecular mass spectra of toxins and drugs in order to facilitate the management and retrieval of mass spectra for nerve agents,metabolites and other small molecules.Methods Requirement analysis and functional design were performed using software engineering methods.The Spec2Vec algorithm was used for vector representation of mass spectra,while SMILES molecular structures were vectorized using the extended connectivity fingerprint(ECFP).A data storage model integrating structured information and vector representations was established using the Milvus database.Similarity search of mass spectra and molecular structures was conducted via vector similarity comparison and the FlashEntropySearch algorithm.Results The constructed database of mass spectra encompassed over 400,000 entries from such sources as OCAD,NIST,MASSBANK,metabolic products,and natural products of TCM,which was capable of searching for similarities in mass spectra and molecular structures.On a standard server,similarity search of mass spectra took no more than 5 seconds,while that of molecular structures took no more than 1 second.Conclusion The system enables efficient management of complex mass spectra and provides rapid retrieval and comparison of mass spectra-related information through advanced vector indexing technology,offering robust data support and research tools for toxicology and pharmacology.

The oropouche virus (OROV) poses a threat to pregnant women and fetuses, potentially causing fetal neurological defects and even stillbirth, which has caused global attention. OROV is an arthropod-borne virus belonging to the Orthobunyavirus genus in the Bunyavirales order, primarily transmitted by arthropods and causing oropouche fever. This article reviews the etiological characteristics, epidemiological distribution, clinical symptoms, detection methods, and prevention strategies of OROV. OROV is prevalent in Central and South America, with a sharp increase in cases reported in Brazil in 2024. The virus's symptoms resemble those of several other arthropod-borne viral diseases, which can lead to misdiagnosis. Currently, there are no specific drugs or vaccines available, and treatment is mainly supportive. Culicoides paraensis and Culex quinquefasciatus are among the significant vectors of OROV. Furthermore, the article analyzes the distribution of Culex quinquefasciatus in China, highlights the risk of imported cases, proposes targeted prevention and control strategies, and underscores the significance of international cooperation in disease prevention and control.
