Objective Guided by"Medical Record Management Quality Control Indicators(2021 Edition)"(hereafter regarded as Medical Record Quality Indicators),this study aims to evaluate the quality of inpatient hospice medical records at a tertiary hospital in Guangzhou.Methods A total of 1,071 inpatient hospice medical records from the year 2023 in a tertiary gen-eral hospital in Guangzhou were selected for evaluation.The evaluation focused on three aspects:documentation compliance of documentation of critical examinations(including CT/MRI,pathology,and pathogen examinations),the compliance rate of treat-ment behavior records(encompassing antibiotic usage,chemotherapy or radiotherapy or targeted or immunotherapy for malignant tumors,and surgical records),and the incidence of unreasonable duplication within medical record.Results The compliance rate for major examination records ranged from 47.7％to 100.0％,with the lowest compliance rate(47.7％)observed in docu-mentation of pathogen culture analysis.Treatment behavior documentation compliance varied from 49.1％to 100.0％,with the lowest compliance rate of 49.1％observed in the recording of antibiotic usage.Rates of inappropriate duplication ranged from 1.0％to duplication(63.1％),with the highest rate of 63.1％occurring when initial progress notes replicated admission histo-ries without synthesis(63.1％).Conclusion The Medical Record Management Quality Control Indicators serves as an effective tool for evaluating the dimensions of medical record quality and offers a systematic framework for enhancing documentation integri-ty within hospitals.

Objective:To assess the efficacy and safety of Gongxuening Capsules in reducing post-abortion bleeding following artificial abortion.Methods:A multicenter, randomized, double-blind study was conducted. From May 31, 2022 to March 31, 2023, 484 women who underwent vacuum aspiration abortion for early intrauterine pregnancy were enrolled in 11 centers and randomly assigned to control group and the study group at a 1∶1 ratio using a center-block randomization method. Control group were administered a placebo of Gongxuening Capsules for 9 d, while the study group received the actual Gongxuening Capsules for the same duration. The outcomes measured included vaginal bleeding volume, duration of vaginal bleeding, endometrial thickness, time to menstrual recovery, and complications.Results:1) A total of 484 subjects were enrolled, and 472 completed the study. Totally 450 subjects were included in the efficacy analysis set, with 224 in control group and 226 in the study group; 468 subjects were included in the safety analysis set, with 236 in control group and 232 in the study group. The baseline characteristics of the two groups were comparable (all P>0.05). 2) The vaginal bleeding volume was lower in the study group [(13.30±12.14) mL] than in control group [(19.00±17.67) mL, P<0.001]. The proportion of subjects in the study group with bleeding days less than 4 d [29.65% (67/226)] was higher than that in control group [19.20% (43/224), P=0.010]. 3) No significant differences were observed between the two groups in terms of time to menstrual recovery and endometrial thickness (all P>0.05). 4) In the study group, 3 subjects experienced non-therapeutic-related complications, while 11 subjects in control group. The incidence of complications was lower in the study group [1.29% (3/232)] than in control group [4.66% (11/236), P=0.033]. Conclusion:The administration of Gongxuening Capsules to women following artificial abortion significantly reduced vaginal bleeding volume and was associated with good safety, with the treatment being well-tolerated by the subjects.

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.

Objective To investigate the value of MRI of the sternal end of clavicle in bone age assessment in Chinese population,especially its applicability in the determination of criminal responsible age.Methods A total of 431 patients aged from 10.00 to 29.99 years with neck or chest MRI were retrospectively collected.According to the Schmeling grading method,the epiphyseal development of the clavicle MRI was divided into five grades.The consistency of methods was evaluated.The correlation and general descriptive analysis between MRI grades and age was analyzed.The sex difference was analyzed.Curve fitting was used to establish a nonlinear model between age and grades.Results The grades of clavicle MRI showed a significant age-related trend(Figure 2),and the correlation was 0.861(0.887 in males and 0.840 in females).Except for grade 1,there was no significant difference between males and females in other grades.The minimum age of male grade 3 was greater than 14 years old,and the minimum age of female grade 3 was greater than 16 years old.The minimum age in grade 4 and grade 5 was over 18 years old in both sexes.The best curve fitting model was cubic model for both sexes(R2=0.805 for men and 0.722 for women).Conclusion Clavicle MRI can be used for the assessment of bone age in Chinese population.Complete epiphyseal plate closure can be used as a reliable indicator for the determination of age at 18 years old,and it is expected to achieve radiation-free forensic bone age assessment.

Spinocerebellar ataxia 17 (SCA17) is an autosomal dominant cerebellar ataxia caused by an abnormal expansion of the CAG/CAA sequence in the TATA-box binding protein ( TBP) gene. According to CAG size range, there are 2 clusters: reduced-penetrance in low-range expansions and full-penetrance in larger expansions. Here, a patient genetically diagnosed with SCA17 and with 43 CAG repeats in the TBP gene, presenting symptoms resembling multiple system atrophy (MSA), is reported. Further review of previously reported cases of SCA17 with a small range of expansions shows the clinical manifestations of SCA17 are highly heterogeneous, of which clinicians need to have sufficient awareness. For patients clinically suspected of having MSA, even if their clinical features and imaging manifestations more strongly support the sporadic neurodegenerative disease, SCA17 should still be considered as one of the differential diagnoses.
