Digital and intelligent technologies serve as the core engine driving the inheritance of the essence and the innovation while upholding the fundamentals of traditional Chinese medicine（TCM）. Currently， the digital and intelligent transformation of TCM has undergone four developmental stages， exhibiting inherent characteristics such as long-term inevitability， objective standardization， and ecological evolution. By introducing quantitative metrics， digital and intelligent technologies have achieved breakthroughs in TCM knowledge inheritance and innovation， clinical diagnosis and treatment， and herbal medicine supply. The practical applicability of methodological innovations has been empirically validated， though significant disparities exist in technological adaptability and application depth across different fields. Overall， the digital and intelligent transformation of TCM remains in its nascent stage， grappling with multiple structural challenges：weak data foundations， inadequate technological adaptability， incomplete institutional frameworks， shortages of multidisciplinary talent， lagging policies and regulations， and urban-rural digital divide. In order to foster sustainable development and modernization of TCM， this paper establishes a six-dimensional collaborative governance framework of encompassing data， technology， organization， institutions， environment and ethics， which is rooted in data governance and digital governance theories. Future efforts should center on standardization， integration， and ecosystem development to build a data and technology foundation. Focus should be placed on deepening innovation and application of key TCM-specific technologies， while simultaneously strengthening interdisciplinary talent cultivation， improving institutional mechanisms and policy frameworks， and increasing support for rural areas. By adopting a people-centered and technology-empowered approach， we can overcome developmental constraints and unleash the powerful driving force of digital and intelligent technologies for the inheritance of TCM.

Objective To explore the effects of sacral neuromodulation (SNM) on urodynamic parameters during the storage phase in patients with neurogenic bladder (NB), so as to provide reference for evaluating the efficacy of SNM. Methods A total 49 NB patients undergoing SNM at our hospital during Oct.2012 and May 2025 were enrolled. Baseline data and video-urodynamic parameters were collected. Changes in maximum cystometric capacity, maximum detrusor pressure during storage phase, and bladder compliance before and after treatment were assessed. Improvements in detrusor overactivity (DO) and vesicoureteral reflux (VUR) were also analyzed. Results Among the 49 patients,27 were male and 22 were female, with a mean age of (37.41±15.15) years, a median disease duration of 5.0 (2.0,15.5) years, and a median follow-up of 11 (1,32) months. Up to 37 patients (75.5%) received permanent sacral nerve pulse generator implantation (permanent implant group), while the remaining 12 were classified as the non-permanent implant group. Before and after the test period, all patients showed a significant increase in maximum cystometric capacity [ (218.0 (93.0,358.5) mL vs.300.0 (238.5, 400.0) mL, P<0.001], a decrease in maximum detrusor pressure during the filling phase [32.0 (13.5,71.0) cmH_2 O vs. 20.0 (9.0,50.0) cmH_2 O, P<0.001], and an improvement in bladder compliance [11.8 (8.3,25.6) mL/cmH_2 O vs.26.7 (8.6,44.1) mL/cmH_2O, P<0.001]. In the permanent implant group, comparisons before and after the test period showed an increase in maximum bladder capacity [ (239.16±147.23) mL vs. (312.24±121.83) mL, P<0.001], a decrease in maximum detrusor pressure during filling[32.0 (15.0,58.0) cmH_2 O vs.15.0 (9.0,41.0) cmH_2 O, P<0.05], and improved bladder compliance [10.8 (8.3,23.6) mL/cmH_2 O vs.28.6 (8.6,41.4) mL/cmH_2 O, P<0.001]. No statistically significant differences in these parameters before and after the test period were observed in the non-permanent implant group (P>0.05). A total of 17 patients in the permanent implant group underwent follow-up video urodynamics. Compared to pre-test values, significant improvements were observed in maximum detrusor pressure during filling, and bladder compliance both at the end of the test period and at the last follow-up (P<0.05). However, no statistically significant differences were found in maximum cystometric capacity, maximum detrusor pressure during filling, and bladder compliance between the end of the test period and the last follow-up (P>0.05). Among the 49 patients,21 had DO and 20 had VUR. Both DO and VUR showed improvement after the test period and at the last follow-up. Conclusion SNM can effectively improve storage function in NB patients, ameliorate detrusor overactivity and bladder compliance, and relieve or eliminate VUR in some patients. Long-term follow-up confirms that SNM provides stable therapeutic effects, demonstrating significant clinical value.

Objective:To investigate the carriage of the thalassemia gene in sperm donors in Chongqing,China by analyzing the thalas-semia screening and gene mutation types of sperm donors in Chongqing Human Sperm Bank(CHSB),and to provide a reference for thalassemia screening in sperm donors in Chongqing.Methods:Blood samples were collected from 488 sperm donors in CHSB(donors with all tests qualified during the quarantine)from December 2021 to August 2024.A complete blood count analysis was performed to measure the mean corpuscular volume(MCV)and mean corpuscular hemoglobin(MCH).Polymerase chain reaction(PCR)/agarose gel electrophoresis was used to detect deletional α-thalassemia mutations.PCR and DNA reverse dot blot hybridization were used to detect 3 common non-deletional α-thalassemia mutations and 17 common β-thalassemia mutations.The test results were then analyzed.Results:Among the 488 sperm donors aged 25.64±4.95 years,15(3.07％,all Han nationality)tested positive for thalassemia.This carriage rate was lower than that of the thalassemia population in Chongqing(9.24％).Among the 15 thalassemia carriers,13 had deletional α-gene mutations(-α3.7 genotype in 11 cases[73.33％],-α4.2 genotype in 1 case[6.67％],and-SEA genotype in 1 case[6.67％]),and 2 had non-deletional α-gene mutations(both with the WSM heterozygous mutation).There was only 1 case of abnor-mal MCV and MCH2 indicators among thalassemia carriers(screening positive rate was 6.67％).Conclusion:Thalassemia screening in sperm donors in CHSB reveals a low thalassemia carriage rate,reflecting geographic(predominantly Sichuan and Chongqing ori-gins)and demographic(healthy men of childbearing potential)characteristics.Given the significant impact of thalassemia on the off-spring conceived through sperm donation,it is recommended to conduct thalassemia gene screening among sperm donors in human sperm banks.

Objective To observe the efficacy of Cuofeng San in the treatment of anterior circulation cerebral infarction(ACCI)of patients with syndrome of wind and phlegm blocking collaterals.Methods A total of 150 ACCI patients were collected in this study,and they were divided into the control group and the treatment group using a random number table method,with 75 cases in each group.The control group was given standardized intervention according to the stroke diagnosis and treatment guidelines,while the treatment group was treated with modified Cuofeng San on the basis of the control group.Both groups were treated continuously for 2 weeks.The treatment effects were compared between the two groups before and after treatment,including the National Institutes of Health Neurological Impairment Scale(NIHSS)score,Barthel Index(BI)score of daily activity ability,scores of syndrome of wind and phlegm blocking collaterals,serum levels of neuron specific enolase(NSE),S100 calcium binding protein B(S100B),monocyte chemoattractant protein-1(MCP-1)and vascular endothelial cell calcium binding protein(VE-cadherin).Results The total effective rate of ACCI patients was higher in the treatment group than that in the control group(93.3％vs.81.3％,P＜0.05).After 1 week and 2 weeks of treatment,the NIHSS score and wind phlegm obstruction syndrome score decreased in both groups compared to those before treatment,while the BI score increased,and the improvement was more significant in the treatment group(P＜0.05).After the end of the treatment course,serum levels of NSE,S100B,MCP-1 and VE-cadherin decreased compared to those before treatment,and the decrease was more significant in the treatment group(P＜0.05).Conclusion The modified Cuofeng San has a significant effect on the treatment of wind phlegm obstruction syndrome in patients with ACCI acute phase.It can improve neurological function and enhance daily activity ability.

Diseases caused by animal virus infection seriously restricts the healthy development of animal husbandry.In-depth study of the molecular mechanism of viral replication and pathogenesis will provide theoretical basis for screening vaccine and drug targets.N6-methyladenosine(m6 A)modification occurs extensively in viral and host transcriptomes and affects viral replication and pathogenicity by regulating gene expression,which acts as a novel regulator of gene expression in addition to DNA and protein modifications.Insight into the regulatory molecular mechanism of m6 A modification in virus infection is the research hotspots and frontiers.In recent years,there are re-ports of alternation of the m6 A modification-associated epitranscriptomes and related function a-nalysis during virus infection.Here,we summarize the alternation of the epitranscriptomes induced by African swine fever virus(ASFV),porcine reproductive and respiratory syndrome virus(PRRSV),porcine epidemic diarrhoea virus(PEDV),cestode virus(CSFV),porcine pseudorabies virus(PRV),Marek's disease virus(MDV),Newcastle disease virus(NDV),avian leukaemia virus(ALV)and duck hepatitis A virus(DHAV)infection,and the subsequent effects on viral replica-tion and pathogenicity.We also discuss the potential role and molecular mechanism of m6 A modification in animal virus replication and pathogenesis,which will contributes to the prevention and control for animal disease.

Objective:To evaluate the role of nemo-like kinase (NLK) in lipopolysaccharide (LPS)-induced inflammatory responses of mouse bone marrow-derived macrophages (BMDMs) and the relationship with glycolysis.Methods:BMDMs were extracted from the wild type (WT) and NLK knockout (NLK -/-) C57BL/6 mice of either sex, aged 6-8 weeks, weighing 20-25 g, were used in this study. After induction, differentiation, maturation and purity identification, BMDMs were divided into phosphate buffer solution (PBS) control group (WT+ PBS group, NLK -/-+ PBS group, n=18) and LPS group (WT+ LPS group, NLK -/-+ LPS group, n=18) by a random number table method. LPS at a final concentration of 1 μg/ml was added to stimulate mature BMDMs for 6 h in LPS group, while the equal volume of PBS was given instead in PBS group. The cell viability was measured by Calcein/PI staining, and the expression of cellular NLK, inflammatory factors (tumor necrosis factor-alpha [TNF-α], interleukin-1 beta [IL-1β] and IL-6) and key glycolytic enzymes (hexokinase 2 [HK2], pyruvate kinase M2 (PKM2) and lactate dehydrogenase A [LDHA])mRNA was detected by real-time fluorescent quantitative polymerase chain reaction. Western blot was used to detect the expression of NLK, HK2, PKM2 and LDHA. The concentrations of TNF-α, IL-1β and IL-6 in the supernatant were determined by enzyme-linked immunosorbent assay. Glucose uptake and lactic acid production were measured by hexokinase method and colorimetric method respectively. Results:Compared with WT-type BMDMs, the expression of NLK protein and mRNA in NLK -/--type BMDMs was significantly down-regulated ( P<0.05). Compared with WT+ PBS group, the BMDM viability was significantly decreased, the expression of TNF-α, IL-1β and IL-6 was up-regulated, the concentrations of TNF-α, IL-1β and IL-6 in the supernatant were increased, the expression of NLK, HK2, PKM2 and LDHA protein and mRNA was up-regulated, and the glucose uptake and lactic acid production were increased in WT+ LPS group ( P<0.05). Compared with WT+ LPS group, the BMDM viability was significantly increased, the expression of TNF-α, IL-1β and IL-6 was down-regulated, the concentrations of TNF-α, IL-1β and IL-6 in the supernatant were decreased, the expression of NLK, HK2, PKM2 and LDHA protein and mRNA was down-regulated, and the glucose uptake and lactic acid production were decreased in NLK -/-+ LPS group ( P<0.05). Conclusions:NLK may enhance LPS-induced inflammatory responses of BMDMs by promoting glycolysis in BMDMs of mice.

Objective:To evaluate the effect of arctigenin (ARG) on cognitive dysfunction induced by sevoflurane anesthesia in aged rats and the role of autophagy-mediated pyroptosis.Methods:Fifty SPF male Sprague-Dawley rats, aged 18-20 months, weighing 550-600 g, were divided into 5 groups ( n=10 each) using a random number table method: control group (C group), sevoflurane anesthesia group (Sev group), sevoflurane anesthesia+ ARG group (Sev+ ARG group), sevoflurane anesthesia+ autophagy inducer rapamycin group (Sev+ RAPA group), and sevoflurane anesthesia+ ARG+ autophagy inhibitor 3-methyladenine (3-MA) group (Sev+ ARG+ 3-MA group). Except for group C, the rats in the other groups inhaled 6% sevoflurane for 3 h to establish the cognitive impairment model. At 30 min before anesthesia, ARG 20 mg/kg was intraperitoneally injected in Sev+ ARG group, rapamycin 7.5 mg/kg was intraperitoneally injected in Sev+ RAPA group, and ARG 20 mg/kg (dissolved in dimethyl sulfoxide) was intraperitoneally injected, followed by immediate intraperitoneal injection of 3-MA 1.5 mg/kg in Sev+ ARG+ 3-MA group. The equal volume of dimethyl sulfoxide was intraperitoneally injected in C group and Sev group. The Morris water maze test was conducted to assess the cognitive function at 48 h after the end of administration. After completion of the Morris water maze test, the hippocampal tissue was taken under deep anesthesia for observation of the pathological changes (after HE staining) which were scored and for determination of neuronal pyroptosis (after propidium iodide staining) and expression of neuronal autophagy-related proteins (microtubule-associated protein 1 light chain 3 [LC3], Beclin-1, p62), pyroptosis-related proteins (NOD-like receptor protein 3 [NLRP3], apoptosis-associated speck-like protein containing a CARD [ASC], pro-cysteine aspartate-specific protease 1 [pro-caspase-1], cleaved-caspase-1, gasdermin D [GSDMD], and N-terminal fragment of gasdermin D [GSDMD-N], interleukin-1β [IL-1β] and IL-18). Results:Compared with C group, the escape latency was significantly prolonged, the time of staying at the original platform quadrant was shortened, the number of crossing the original platform was reduced, the hippocampal injury score and neuronal pyroptosis rate were increased, LC3Ⅱ/LC3Ⅰ ratio was decreased, the expression of Beclin-1 was down-regulated, the expression of p62, NLRP3, ASC, IL-1β and IL-18 was up-regulated, and the cleaved-caspase-1/pro-caspase-1 ratio and GSDMD-N/GSDMD ratio were increased in Sev group ( P<0.05). Compared with Sev group, the escape latency was significantly shortened, the time of staying at the original platform quadrant was prolonged, the number of crossing the original platform was increased, the hippocampal injury score and neuronal pyroptosis rate were decreased, LC3Ⅱ/LC3Ⅰ ratio was increased, the expression of Beclin-1 was up-regulated, the expression of p62, NLRP3, ASC, IL-1β and IL-18 was down-regulated, and the cleaved-caspase-1/pro-caspase-1 ratio and GSDMD-N/GSDMD ratio were decreased in Sev+ ARG group and Sev+ RAPA group ( P<0.05). Compared with Sev+ ARG group, the escape latency was significantly prolonged, the time of staying at the original platform quadrant was shortened, the number of crossing the original platform was reduced, the hippocampal injury score and neuronal pyroptosis rate were increased, LC3Ⅱ/LC3Ⅰ ratio was decreased, the expression of Beclin-1 was down-regulated, the expression of p62, NLRP3, ASC, IL-1β and IL-18 was up-regulated, and the cleaved-caspase-1/pro-caspase-1 ratio and GSDMD-N/GSDMD ratio were increased in Sev+ ARG+ 3-MA group ( P<0.05). Conclusions:AGR can alleviate sevoflurane anesthesia-induced cognitive dysfunction in aged rats, and the mechanism is related to reduction of autophagy-mediated cell pyroptosis.

Objective To investigate the value of chest contrast-enhanced CT(C-CECT)combined with artificial intelligence iterative reconstruction(AIIR)for bronchial artery(BA)imaging.Methods Seventy patients who underwent C-CECT were prospectively enrolled.The images were reconstructed with AIIR(AIIR group)and hybrid iterative reconstruction(HIR,HIR group),respectively.The overall image quality,the traceability of BA,the sharpness of BA and the diagnostic confidence of abnormalities of BA were subjectively graded using a 5-point scale by two radiologists,respectively.The subjective scores and inter-observer agreement were compared between groups.The noise(SD)in reconstructed images of thoracic aorta,pulmonary trunk,BA and spinal erectors,the contrast-to-noise ratio(CNR)of the above 3 arteries relative to spinal erectors,and the diameters of BA at the origin,bifurcation and pulmonary hilum were compared between groups.Results The scores of the overall image quality,the traceability of BA,the sharpness of BA and the diagnostic confidence of abnormalities of BA were all significantly higher in AIIR group than those in HIR group(all P＜0.001),all with good inter-observer agreement(Kappa=0.46-0.73).SD of the aorta,pulmonary artery trunk,BA and erector spinal muscle in AIIR group were lower than those in HIR group,while CNR of above 3 arteries were higher than those in HIR group(all P＜0.05).No significant difference of the diameter of BA at each position was found between groups(all P＞0.05),while the consistency of measurement of AIIR group was higher than that of HIR group(intra-class correlation coefficient:0.89-0.94 vs.0.63-0.78).Conclusion C-CECT combined with AIIR could significantly improve imaging quality and diagnostic confidence of BA.

Objective:To investigate the measurement differences between mainstream and sidestream partial pressure of end tidal carbon dioxide(PetCO2)monitoring techniques in mechanically ventilated patients,as well as the correlation with partial pressure of arterial blood carbon dioxide(PaCO2)and clinical applicability,and to provide a basis for the rational selection of monitoring methods in the clinic.Methods:A total of 169 patients who underwent invasive mechanical ventilation in the operating room of the First Affiliated Hospital of Bengbu Medical University from August to November 2024 were selected to be monitored by three monitoring techniques of mainstream PetCO2,sidestream PetCO2 and PaCO2,respectively,and the 243 sets of valid pairwise data monitored by the three monitoring techniques were recorded,analyzed for correlation and deviation,and performed PaCO2 and PetCO2 were stratified and analyzed.Likert scales were used to analyze the subjective ratings of the 3 monitoring techniques of mainstream PetCO2,sidestream PetCO2,and PaCO2 by the 31 health care professionals who used the study.Results:Both mainstream and sidestream PetCO2 correlated with PaCO2(r=0.554,0.515,P<0.05),and mainstream PetCO2 correlated better than sidestream;mainstream PetCO2 was lower than the concurrent PaCO2 by 6.00 mmHg,and the 95%limit of agreement(95%LoA)was±6.28 mmHg,both lower than that of sidestream by 8.24 mmHg and±7.41 mmHg.8.24 mmHg and±7.41 mmHg.The dispersion of sidestream PetCO2 monitoring values was greater,especially at high PaCO2 levels.Mainstream method PetCO2 had the highest correlation with PaCO2 in gynecologic patients(r=0.820,P<0.05),and sidestream method PetCO2 underestimated PaCO2 more markedly in gastrointestinal and hepato-biliary-pancreatic surgery patients.The deviation of oxygenation index≤300 mmHg was significantly greater than that of patients with oxygenation index>300 mmHg,and the tendency of underestimation was more significant at high PaCO2.31 healthcare experts evaluated that the mainstream PetCO2 monitoring method was outstanding in terms of accuracy and real-time,and that the sidestream method of PetCO2 monitoring was advantageous in terms of ease of operation and management of consumables.Conclusion:In patients who receive mechanical ventilation,the precision,accuracy and real-time of mainstream PetCO2 monitoring are better,which is suitable for patients with rapid changes in disease condition or patients at risk of hypercapnia.The sidestream method is suitable for non-intubated or transported patients,but it is easy to be underestimated at high PaCO2,and it needs to be corrected regularly in combination with arterial blood gas.The clinical application should rationally choose monitoring method after a comprehensive assessment based on the patient's disease condition,oxygenation status,and the scenario of use.
