OBJECTIVE To investigate the application status of prescription pre-review systems in healthcare institutions of Yunnan province， evaluate their system functions and management capabilities， and provide a practical basis for promoting rational drug use. METHODS A questionnaire survey was conducted among public healthcare institutions at or above the secondary level in Yunnan province to investigate the deployment status of the systems. A capability maturity assessment framework was constructed， encompassing 6 dimensions and 39 indicators， including real-time prescription review， prescription correlation review， rule setting， evidence-based information support， prescription authority management， and system operation management. This framework was then used to evaluate the institutions that had implemented the pre-review systems. RESULTS A total of 100 valid questionnaires were collected， with 37 institutions having adopted prescription pre-review systems， mainly tertiary hospitals. The system predominantly adopted a modular architecture and was embedded into the hospital information system through application programming interfaces and middleware， providing certain capabilities for real-time prescription risk identification. Evaluation results indicated that basic functions such as reviewing indications， contraindications， and drug compatibility performed well， while deficiencies remained in functions related to parenteral nutrition prescription， review of drug dosage for specific diseases， individual patient characteristic recognition， and rule setting. Moreover， the construction of review centers and establishment of management systems were also not well-developed. CONCLUSIONS The overall application rate of prescription pre-review systems in Yunnan province remains low. System functions and management mechanisms require further improvement. It is recommended to enhance information infrastructure in lower-level institutions and explore regionally unified review models to promote standardized and intelligent development of prescription review practices.

Fresh-cut processing constitutes a pivotal technique in the origin processing of Chinese medicinal materials， with a long history documented in multiple materia medica. In recent years， it has garnered national policy support for its ability to prevent component loss and low processing efficiency associated with traditional drying-before-cutting methods. As of August 2025， 26 provinces and municipalities nationwide have cumulatively published 789 species for fresh-cut processing. Among these， 78 were included in the 2025 edition of the Pharmacopoeia of the People's Republic of China. However， the practice continues to face common challenges and difficulties， including ambiguous scientific understanding， fragmented standards， limited quality control approaches， and poor process stability. Based on this， this paper synthesises years of research findings to systematically elucidate the core mechanisms of fresh-cut processing. These encompass alterations to herbal tissue structure during cutting， post-processing changes in constituents， and physiological-biochemical processes such as plant stress responses and shifts in endogenous enzyme activity. It also summarises influencing factors， including inherent herbal properties， cutting timing and methods， and environmental conditions like temperature， humidity， and microbial presence. Based on this overview of fresh-cutting mechanisms， subsequent research should advance in four directions：Clarifying the scientific principles of fresh-cutting， overcoming technical bottlenecks， upgrading intelligent equipment， and establishing quality standards and evaluation systems. This study provides a theoretical foundation and scientific basis for future research on fresh-cutting in traditional Chinese medicine（TCM）， promoting its deeper practical application within the industry and contributing to the high-quality development of TCM industry and the modernization of TCM.

Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

OBJECTIVE: To evaluate the clinical significance of a hemizygous c.1042-10G>C variant of the SLC9A7 gene NM_001257291.2) previously identified in individuals with neurodevelopmental disorders, and to provide an evidence-based guidance for prenatal genetic counseling. METHODS: Four families presented at the Medical Genetics Center of Henan Provincial People's Hospital between December 2022 and July 2024 were included in this study. Phenotypic information and biological samples were collected from family members. Genomic DNA was extracted and subjected to whole-exome sequencing and copy number variation analysis to identify candidate pathogenic variants. Sanger sequencing was performed for familial co-segregation analysis. Reverse-transcription PCR was used to assess the RNA splicing pattern of the variant in peripheral blood samples. Quantitative PCR was employed to analyze the expression profiles of various SLC9A7 transcripts in fetal brain tissue and peripheral blood samples. Pathogenicity of the variant was classified based on guidelines from the American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of Henan Provincial People's Hospital (Ethics No.: 2021-171). RESULTS: Six hemizygous males carrying the SLC9A7 c.1042-10G>C variant were identified among the four families, which included three adult males and two male infants with normal phenotypes. Only one affected male from family 3 exhibited global developmental delay, short neck, webbed neck, ocular dysplasia, and congenital corneal leukoma. He also had a history of perinatal asphyxia and carried an additional hemizygous variant HUWE1 c.12283C>G. Reverse-transcription PCR showed no aberrant splicing in heterozygous or hemizygous carriers compared to healthy controls, suggesting that the variant does not affect RNA splicing. Quantitative PCR revealed that NM_001257291.2 is the predominant transcript expressed in fetal brain tissue and peripheral blood. CONCLUSION The SLC9A7 c.1042-10G>C variant does not alter RNA splicing and is present in multiple phenotypically normal males, which supported its classification as a benign variant.

OBJECTIVE: To investigate the clinical phenotype and genetic characteristics of an infertile woman carrying a novel PADI6 gene variant. METHODS: An infertile woman who visited the Medical Genetics Center of Henan Provincial People's Hospital on April 29, 2024 was selected as the study subject. Clinical data of the proband and her family members were collected. Peripheral blood samples were obtained from the proband and her husband for genomic DNA extraction. Whole-exome sequencing (WES) was performed. Candidate variant was verified among the family members by Sanger sequencing. The pathogenicity of candidate variant was classified according to the American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants. Relevant literature on the pathogenic variants of the PADI6 gene was reviewed for genotype-phenotype correlation analysis. This study was approved by the Medical Ethics Committee of Henan Provincial People's Hospital (Ethics No.: 2021-171). RESULTS: The proband was a 35-year-old woman who underwent two oocyte retrieval cycles, yielding a total of five oocytes, with all embryos arrested at day 3 post-fertilization. WES identified a homozygous PADI6 variant, c.367+4_367+7del. In vitro splicing assay confirmed that this variant can cause skipping of exon 3, leading to a frameshift and alterations in the protein structure or premature termination of translation. Literature review identified 12 relevant publications, and the PADI6 c.367+4_367+7del was determined to be a novel variant. CONCLUSION The homozygous PADI6 c.367+4_367+7del variant probably underlay the pathogenesis of infertility in the proband.

Objective:To evaluate the incidence and risk factors of pneumonia in patients with thoracic cancer treated with immunotherapy combined with radiotherapy (RT).Methods:The clinic data of 265 patients with thoracic cancer who received RT and at least 2 cycles of immunotherapy at Renmin Hospital of Wuhan University between January 2020 and January 2024 were retrospectively analyzed. Patients were divided into 2 groups according to treatment sequence: 100 patients with sequential immunotherapy after RT, 165 patients with RT after immunotherapy, including sequential RT after immunotherapy (119 cases) and concurrent RT with immunotherapy (46 cases). The occurrence and grading of treatment-related pneumonia were determined by clinical symptoms, signs, and chest CT findings. The relationship between interval time window of different treatment methods and pneumonia was analyzed by Pearson correlation analysis. χ2 test was used for univariate analysis of risk factors, and logistic regression for multivariate analysis. Results:In the sequential immunotherapy after RT group, the incidence of pneumonia was 12.0% (12/100), with grade ≥2 pneumonia in 4.0% (4/100). The interval time between RT and immunotherapy, has a strong negative correlation with pneumonia incidence and grade ≥2 pneumonia incidence ( r=-0.88, -0.79; both P<0.001). When immunotherapy was initiated ≥7 weeks after RT, the incidence of pneumonia significantly decreased to 5% ( P=0.020), with no grade ≥2 cases. In the immunotherapy followed by sequential / concurrent RT cohort, the incidence of pneumonia was significantly higher in the concurrent subgroup compared with the sequential subgroup [65% (30/46) vs. 44.5% (53/119), P=0.027], and the comparison of the incidence of grade ≥2 pneumonia was the same [33% (15/46) vs. 14.3% (17/119), P=0.014]. The interval time window of RT after immunotherapy was strongly negatively correlated with the incidence of pneumonia and grade ≥2 pneumonia ( r=-0.77, -0.83; both P<0.001). When RT was initiated ≥4 weeks after immunotherapy, the incidence of pneumonia significantly decreased ( P<0.001). Pneumonia incidence differed significantly across RT target sites (intrapulmonary vs. extrapulmonary), total dose (<60 Gy vs. ≥ 60 Gy), and fractionation regimen (conventional vs. hypofractionation) ( P < 0.001, = 0.008, = 0.031), but was not associated with age, gender, smoking history, type of immune checkpoint inhibitor (anti-programmed death-1 vs. anti-programmed death ligand-1), or the number of prior immunotherapy cycles (all P > 0.05). Multivariate analysis identified RT within the lung and interval time of RT after immunotherapy ≤ 4 weeks as independent risk factors for the incidence of pneumonia (both P < 0.001). Conclusions:The interval window between RT and immunotherapy is a critical determinant of pneumonia incidence. Delaying immunotherapy for more than 7 weeks after RT, or delaying RT for more than 4 weeks after immunotherapy, can significantly reduce the risk of radiation-related pneumonia.

Objective:To construct a medical quality evaluation index system for inpatients in public hospitals based on the life cycle theory,starting from the entire process of medical treatment.Method:A comprehensive study was conducted on the screening of medical quality evaluation indicators for hospitalized patients using literature analysis,key informant interviews,and expert inquiry methods.Results:The effective recovery rate of the two rounds of expert consultation was 100%,with high enthusiasm from the experts.The authority coefficient was above 0.7,and Kendall's W coordination coefficient was 0.267(P＜0.05).The evaluation indicators for medical quality of hospitalized patients,including 3 primary indicators,10 secondary indicators,and 51 tertiary indicators,were determined.Conclusions:The medical quality evaluation index system for inpatients in public hospitals based on the life cycle theory has certain scientificity and reliability.However,the weight analysis of the index system has not been carried out and is still in the theoretical exploration stage.Further empirical research is needed for verification and improvement.

Objective:To investigate the impact of chromate exposure on pulmonary function indices in occupational populations and explore the potential role of alterations in inflammatory indicators in this process.Methods:In July 2024, A cross-sectional analysis was conducted using occupational health examination data of 30875 workers from chromate-related enterprises in Jiangsu Province in 2020 and 2021. Based on the occupational positions and whether there is chromium acid salt exposure in the occupational hazards of the research subjects over the years, they are divided into chromium acid salt exposure group and non-exposure group. For those exposed to chromium acid salts, based on job position descriptions and duration of chromium acid salt exposure, they are further categorized into intermittent exposure group and continuous exposure group; among them, the actual exposure time in the intermittent exposure group is less than half of the working shift time, and the exposure duration is less than the total working life. Pulmonary function test indicators include forced vital capacity (forced vital capacity, FVC) %, first-second forced expiratory volume (forced expiratory volume in one second, FEV 1.0) %, and the ratio of first-second forced expiratory volume to forced vital capacity (FEV 1.0/FVC) %. Peripheral blood samples from the upper limbs of the research subjects were collected on an empty stomach for routine blood tests, selecting neutrophil count, platelet count, and lymphocyte count results, calculating the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). Quantitative data that meet normal distribution are expressed using Mean±SD, while variables that do not meet normal distribution are represented by M ( Q1, Q3). Categorical data are expressed using frequency or proportion (%). Linear variable comparisons between groups use t-tests. Generalized linear models were employed to assess the correlation between chromate exposure and pulmonary function indices, while mixed regression models were utilized to explore potential underlying effects. Results:Compared with the non-exposed group, the pulmonary function indices FVC (%), FEV 1.0/FVC (%), and FEV 1.0 (%) in the chromate-exposed group showed a decreasing trend ( P<0.01), indicating statistically significant differences. As the frequency of chromate exposure increased, the prevalence of pulmonary dysfunction rose. The prevalence rates of obstructive, restrictive, and mixed respiratory dysfunction among the chromate-exposed population (including intermittent exposure and continuous exposure groups) were 0.26%, 4.67%, and 0.12%, which were higher than those in the non-exposed group (0.09%, 0.84%, and 0.07%, respectively). All these differences were statistically significant ( P<0.05). After stratification by gender, a negative correlation was observed between chromate exposure and the inflammatory indicator platelet-to-lymphocyte ratio (PLR) ( P<0.05). Potential effect analysis revealed that PLR played a certain mediating role between chromate exposure and the decline in pulmonary function indices, with a mediating proportion of 2.2%. Conclusion:Chromate exposure in occupational populations may lead to a decline in pulmonary ventilatory function and alterations in peripheral blood inflammatory indicators. Inflammatory indicators may be involved in the pulmonary function decline caused by chromate exposure.

Objective:By systematically evaluate the implementation of GBZ 2.1, so as to provide technical basis for the future revisions of this standard.Methods:From May to October 2023, Based on the pre survey questionnaire, the semi-structured interview method was used to interviews with experts from CDC, Occupational disease prevention and control hospital institutes, employers, occupational hygiene technical service intermediaries and universities, and the inductive method was used to extract the topics and relevant suggestions.Results:Generally, GBZ 2.1 is scientific, practical, progressiveness and operable. There are still some issues such as OELs overlapping and the correspondence between Chinese and English names. The outstanding problem is the coordination with other standard contents.Conclusion:The technical indicators in GBZ 2.1 could adapt to the needs of current practical work. The coordination between standards needs to be clarified, and the new recommended content needs further promotion and exploration on how to implement it.

BACKGROUND:In recent years,brain-computer interface technology has shown significant promise for rehabilitating limb dysfunction in stroke patients.With ongoing research deepening and its broader clinical application,combining brain-computer interface with other rehabilitation therapies to improve limb function has become a focal point of study.OBJECTIVE:To analyze and summarize the efficacy of brain-computer interface combined with various therapies in treating limb dysfunction in stroke patients and to explore the clinical value of these combined strategies.METHODS:The search terms used for the literature review in Chinese databases were"brain-computer interface,BCI,stroke,"while the terms"brain-computer interface,BCI,brain-computer interaction,brain-machine interface,BMI,stroke"were used for English databases.Literature searches were conducted in CNKI,WanFang,VIP,PubMed,Embase,and Web of Science,from the time of database construction to September 2024.Finally,a total of 3 054 articles were retrieved,and 75 articles were included after screening for summarization.RESULTS AND CONCLUSION:Currently,brain-computer interfaces,used alone or in combination with other treatments such as Chinese medical treatment,conventional rehabilitation therapy,or physical factor therapy,are achieving better outcomes in treating limb dysfunction in stroke patients.However,the efficacy of brain-computer interfaces combined with transcranial direct current stimulation for treating upper and lower limb dysfunctions is still debated.Researchers are increasingly recognizing the feasibility of these combined therapies.Yet,challenges such as limited exploration of therapeutic mechanisms,absence of standardized protocols,and small sample sizes hinder their broad application.Future research should therefore focus on understanding the mechanisms by which brain-computer interfaces can enhance effects when combined with other therapies and on standardizing criteria for clinical trials to enable widespread clinical adoption.
