OBJECTIVE To explore the transformation of the dispensing and drug pickup process in traditional Chinese medicine pharmacy （TCM Pharmacy） in our hospital based on data-intelligence-driven， aiming to improve pharmacists’ work efficiency and patients’ drug pickup experience. METHODS Value stream mapping and journey mapping were used to systematically identify non-value-added links in pharmacists’ dispensing process and key pain points in patients’ drug pickup under the traditional process. An intelligent dispensing and drug pickup system for the TCM Pharmacy was developed based on the C# and Android television platforms， and a machine-learning model was adopted to predict patients’ drug pickup waiting time. A comprehensive evaluation was performed from three perspectives： system performance， prediction accuracy， and satisfaction of pharmacists and patients. RESULTS The system successfully streamlined non-value-added links such as “waiting for writing on the board” and “searching for drugs”， and realized multimodal dynamic prompts of dispensing status through auditory （number calling） and visual （television terminal） channels. The constructed model for predicting drug pickup waiting time exhibited good fitting degree and generalization ability （mean absolute error＝4.28 min， R 2 ＝0.882）. The comprehensive satisfaction scores of pharmacists and patients in the traditional mode were significantly increased from （70.99±1.74） and （73.58±1.98） to （90.02±1.30） and （88.61±2.08） in the new system， respectively （ P ＜0.01）. CONCLUSIONS The transformation of the intelligent drug dispensing and pickup system for TCM pharmacy based on data-intelligence-driven effectively improves the efficiency of pharmacists’ dispensing work， realizes process transparency and waiting time predictability， and significantly enhances patients’ drug pickup experience.

Objective:To evaluate the clinical efficacy of acupuncture combined with low-frequency repetitive transcranial magnetic stimulation (rTMS) in the treatment of heart and liver fire hyperactivity syndrome in children with tic disorder; To explore its effects on the levels of serum neurotransmitters in children.Methods:A randomized controlled trial study was conducted. A total of 86 children with heart and liver fire hyperactivity syndrome of tic disorder in our hospital from March 2022 to March 2024 were selected as the observation objects and divided into 2 groups using the random number table method, with 43 cases in each group. The control group was treated with rTMS, while the observation group was treated with combined acupuncture on the basis of the control group. Both groups were treated continuously for 8 weeks. The TCM syndrome scores were conducted before and after the treatment respectively. The Yale Comprehensive Tic Severity Scale (YGTSS) was used to evaluate the severity of clinical symptoms, and the levels of serum γ -aminobutyric acid (γ-GABA), dopamine (DA), and 5-hydroxytryptamine (5-HT) were detected by ELISA. The adverse reactions during the treatment period were recorded and the clinical efficacy was evaluated.Results:The total effective rate was 90.70% (39/43) in the observation group and 72.09% (31/43) in the control group, with statistical significance ( χ2=4.91, P=0.027). After treatment, the scores of convulsion and peristalsis, flushed face and ears, irritability and anger, and red tongue with yellow coating in the observation group were lower than those in the control group ( t values were 3.80, 2.94, 3.26, and 4.22 respectively, P<0.01), and the scores of vocal tics, motor tics and the total score were lower than those in the control group (t values were 7.97, 5.23, and 6.44 respectively, P<0.01). After treatment, the level of γ-GABA in the observation group [(9.72±2.04) μg/L vs. (8.13±1.87) μg/L, t=3.77] was higher than that of the control group ( P<0.01), and DA [(8.98±1.94) μg/L vs. (12.10±2.27) μg/L, t=6.85], levels of 5-HT [(15.20±3.87) μg/L vs. (19.93±3.97) μg/L, t=5.59] were lower than those in the control group ( P<0.01). During the treatment period, the incidence of adverse reactions was 11.63% (5/43) in the observation group and 9.30% (4/43) in the control group, without statistical significance ( χ2=0.12, P=0.725). Conclusion:Acupuncture combined with rTMS can alleviate the tic symptoms of children of tic disorder with heart and liver fire hyperactivity syndrome, improve the neurotransmitter levels and main TCM syndromes of the children, enhance the clinical efficacy and have good treatment safety.

Objective To explore the valve regurgitation status of left heart after the implantation of left ventricular assist device (LVAD) and its effect on prognosis of patients with LVAD implantation. Methods A total of 35 patients with cardiomyopathy who underwent magnetic levitation LVAD implantation at Zhongshan Hospital, Fudan University from February 2021 to July 2024 were retrospectively selected. Clinical data during hospitalization were collected, including preoperative basic data and postoperative valve regurgitation status. Telephone follow-ups were conducted to monitor patients’ survival status and transthoracic echocardiography was used to assess left valve function. Kaplan-Meier survival curves and log-rank test were employed to compare the survival rate of patients with different levels of valve regurgitation. Results The 35 patients had a mean age of (53.9±11.1) years, with 85.7% male, and 3 patients (8.6%) died during hospitalization. Preoperatively, 17 patients (48.6%) had moderate or greater mitral regurgitation, while all 35 patients had less than moderate aortic regurgitation. One month postoperatively, thirty patients were followed up, among which 24 patients (80%) had less than moderate mitral regurgitation, including 11 cases with alleviated regurgitation compared to pre-surgery; 6 patients (20%) had moderate or greater mitral regurgitation, including 4 cases with stable regurgitation and 2 cases with progression of regurgitation compared to pre-surgery; 2 patients (6.7%) had progression of aortic regurgitation to moderate or greater. The follow-up time was 1.2 (1.0, 2.1) years, with 1-year survival rate of 91.4% and 3-year survival rate of 71.1%. Survival analysis showed that the 3-year survival rate of patients with moderate or greater mitral regurgitation one month postoperatively was significantly lower than that of patients with less than moderate regurgitation (66.7% vs 83.3%, P＝0.046). Conclusions After the implantation of magnetic levitation LVAD, most patients showed improvement in mitral regurgitation, while aortic regurgitation remained unchanged. The degree of mitral regurgitation one month postoperatively is associated with prognosis.

AIM: To investigate the effects of Conbercept on various optical coherence tomography(OCT)biomarkers in patients with retinal vein occlusion-related macular edema(RVO-ME), and to analyze the correlation of these biomarker changes with visual prognosis.METHODS: Retrospective study. A total of 57 patients(57 eyes)with RVO-ME, including 25 patients(25 eyes)with central retinal vein occlusion(CRVO)and 32 patients(32 eyes)with branch retinal vein occlusion(BRVO), were enrolled in this study. All the patients received intravitreal injection of conbercept once a month, three times in total. The preoperative and postoperative best-corrected visual acuity(BCVA), and changes in OCT biomarkers, including central macular thickness(CMT), the length of disorganization of the retinal inner layers(DRIL), the number of hyperreflective dots(HRD), the area of intraretinal fluid(IRF), the area of subretinal fluid(SRF), and the length of ellipsoid zone(EZ)disruption were compared. Furthermore, the relationship of these changes with BCVA was analyzed.RESULTS:Compared with the baseline, at 3 mo post-treatment, BCVA(LogMAR)was improved, CMT was decreased, the length of DRIL was shortened, the number of HRD was reduced, the area of IRF was decreased, the area of SRF was reduced, and the length of EZ disruption was shortened(all P<0.05). Spearman correlation analysis showed that there was no correlation between the changes in CMT, the length of DRIL, the number of HRD, the area of IRF, the area of SRF and the change in BCVA before and after treatment(P>0.05). However, the change in the length of EZ disruption was positively correlated with the change in BCVA(rs=0.34, P=0.011), and the R2 value of the fitting curve between the change in the length of EZ disruption and the change in BCVA was 0.113(P=0.011). When comparing the pre- and post-treatment changes in BCVA, the length of DRIL, the number of HRD, the area of IRF, the area of SRF, and the length of EZ disruption between patients in the CRVO group and BRVO group, no significant differences were observed(all P>0.05). In contrast, a significant difference was found in the change in CMT between the two groups(P=0.002).CONCLUSION:Conbercept effectively improves multiple OCT biomarkers in patients with RVO-ME. Repair of EZ disruption is a key driver of visual recovery, and its stability may serve as a novel indicator for personalized decision-making in anti-vascular endothelial growth factor therapy.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective: To analyze the change trends in the body shape indicators and proportions of students in Harbin from 2010 to 2024, and to investigate ergonomic compatibility of functional dimensions of school desks and chairs with current student shape indicators, so as to provide a reference for revising furniture standards of desks and chairs. Methods: Between September and November of both 2010 and 2024, a combination of convenience sampling and stratified cluster random sampling was conducted across three districts in Harbin, yielding samples of 6 590 and 6 252 students, respectively. Anthropometric shape indicators cluding height, sitting height, crus length, and thigh length-and their proportional changes were compared over the 15-year period. The 2024 data were compared with current standard functional dimensions of school furniture. The statistical analysis incorporated t-test and Mann-Whitney U- test. Results: From 2010 to 2024, average height increased by 1.8 cm for boys and 1.5 cm for girls; sitting height increased by 1.5 cm for both genders; crus length increased by 0.3 cm for boys and 0.4 cm for girls; and thigh length increased by 0.5 cm for both genders. The ratios of sitting height to height, and sitting height to leg length increased by less than 0.1 . The difference between desk chair height and 1/3 sitting height ranged from 0.4-0.8 cm. Among students matched with size 0 desks and chairs, 22.0% had a desk to chair height difference less than 0, indicating that the desk to chair height difference might be insufficient for taller students. The differences between seat height and fibular height ranged from -1.4 to 1.1 cm; and the differences between seat depth and buttock popliteal length ranged from -9.8 to 3.4 cm. Among obese students, the differences between seat width and 1/2 hip circumference ranged from -20.5 to -8.7 cm, while it ranged from -12.2 to -3.8 cm among non obese students. Conclusion Current furniture standards basically satisfy hygienic requirements; however, in the case of exceptionally tall and obese students, ergonomic accommodations such as adaptive seating allocation or personalized adjustments are recommended to meet hygienic requirements.

Narrow leaf 1 (NAL1) plays an important role in plant branching, while little is known about the roles of this gene in petunias. In this study, PhNAL1b was cloned from Petunia×hybrida cv. Mitchell Diploid, with a total length of 1 767 bp, encoding a protein composed of 588 amino acid residues and containing the peptidase S64 domain. The PhNAL1b promoter region contained several elements involved in the responses to auxin, jasmonic acid, abscisic acid, and light. The expression analysis showed that PhNAL1b had the highest expression level in roots and the lowest expression level in flowers, and its transcription could be inhibited by decapitation and cytokinin. The subcellular localization analysis showed that PhNAL1b was located in the nucleus and was a nuclear protein. Virus-induced gene silencing was employed to downregulate the expression of PhNAL1b, which resulted in significant increases in branch number and plant height. The results indicated that PhNAL1b played an important role in regulating the branching of petunias. This study lays a foundation for revealing the mechanism of NAL1 in regulating branch development and provides genetic resources for plant architecture improvement.

The receptors of Newcastle disease virus(NDV)are sialic acid receptors that mainly in-clude neu5ac-α-2,3gal-β-1,4Glc(SAα2,3Gal)and neu5ac-2-s-α-2,6Gal10Me(SAα2,6Gal).The distribution and abundance of the two receptors in host cells have important effects on virus sus-ceptibility and intracellular proliferation.In order to further explore the effects of sialic acid recep-tors on susceptibility and proliferation characteristics of NDV different strains,the expression lev-els of SAα2,3Gal and SAα2,6Gal receptors on BHK-21 cell membrane were adjusted by overex-pression and RNAi assays,and the TCID50 values were determined after different BHK-21 cells were inoculated with NDV strains Ⅰ and LaSota.The results suggested that NDV strain LaSota preferentially binds to SAα2,6Gal and strain Ⅰ selectively binds to SAα2,3Gal receptor.Further-more,the viral titers of NDV strains LaSota and Ⅰ in cell culture were positively correlated with the expression levels of SAα2,6Gal and SAα2,3Gal receptors on host cell membrane respectively.In conclusion,our studies provide an understanding of the relationship between infectivity of NDV different strains and receptor types of host cell,and provide a method to increase viral titer of NDV for cell-based vaccine production.

To rapidly detect and differentiate Mycoplasma gallisepticum(MG)and Mycoplasma synovialis(MS),two sets of specific primers and TaqMan probes were designed in this study based on the conserved regions of the 16S rRNA gene of two pathogens in NCBI.A dual TaqMan fluorescence quantitative PCR method for simultaneous detection of MG and MS was established by optimizing the reaction conditions,and the specificity,sensitivity,repeatability,and reliability of the method were verified.The results showed that this method could specifically amplify MG and MS without cross reactivity with 21 pathogens.The sensitivity experiment results showed that the detection limits of this method for MG and MS were 5.40×10 1 copies/μL and 6.60 × 10 1 copies/μL,and the sensitivity was 10 to 100 times higher than that of known methods.In addition,the re-sults of repetitive experiments showed that the coefficient of variation within and between groups was less than 1％.Compared with the single PCR amplification method in NY/T 553-2015,the positive sample detection coincidence rate,negative sample detection coincidence rate,and total sample detection coincidence rate were all 100.00％,indicating the strong reliability of this method.Using this method to detect 84 suspected Mycoplasma infected chicken samples,the results showed that the MG positivity rate was 32.14％(27/84),the MS positivity rate was 22.62％(19/84),and the positivity rate of samples infected with MG and MS was 16.67％(14/84).Concurrent-ly,182 healthy chicken cloacal swab samples,118 healthy chicken nasal swab samples,and 74 chicken farm environmental samples were detected,and the results showed that all samples were positive for Mycoplasma.The above results indicate that this method can be applied to the detec-tion of various clinical samples.In summary,the method established in this study had the advanta-ges of high specificity,high sensitivity,and good reproducibility.It could be used for clinical differ-ential diagnosis,epidemiological investigation,and pathogen purification of MG and MS infections.
