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 investigate the clinical manifestations, gene mutation characteristics, imaging and video electroencephalogram (VEEG) characteristics of patients with dentatorubral-pallidoluysian atrophy (DRPLA).Methods:The clinical data of 9 patients with genetically diagnosed DRPLA in the Neurology Center, Beijing Tiantan Hospital, Capital Medical University from January 2018 to January 2023 were collected, and the clinical data of DRPLA patients reported in China were retrieved and summarized.Results:A total of 45 cases were included. The clinical characteristics were summarized as follows: (1) The male to female ratio of 45 patients was 1.00∶1.25, and the age of onset was (28.11±14.58) years. (2) The main clinical symptoms of juvenile type, early-onset adult type and late-onset adult type were analyzed, and the results showed that the frequency of seizures in juvenile type (16/17) was higher than that in early-onset adult type (8/21) and late-onset adult type (2/7), with statistically significant difference (χ 2=15.971, P<0.001). In addition, the frequency of cognitive impairment in juvenile type (16/17) was also higher than that in early-onset adult type (15/21) and late-onset adult type (2/7), also with statistically significant difference (χ 2=10.177, P=0.005). Cognitive impairment, language disorder and involuntary movement were common in early-onset adult patients, and about half of the patients had ataxia. Ataxia and language disorder were more common in late-onset adult patients, while seizures and cognitive impairment were rare. (3) In imaging, cerebellum and brainstem atrophy was the most common, followed by cortical atrophy and white matter lesions. (4) The number of trinucleotide (CAG) repeats was 53-79, and there was a significant negative correlation between the number of CAG repeats and the age of onset ( r=-0.765, P<0.001), that means the younger the age of onset, the higher the number of CAG repeats. (5) In terms of electrophysiology, 21 patients provided complete VEEG data, of which slowed activity (52%, 11/21) and generalized discharge (71%, 15/21) were more common, and focal discharge (33%, 7/21) was uncommon. Conclusions:DRPLA patients can present with epilepsy, cerebellar ataxia, and other clinical manifestations. Brainstem and cerebellar atrophy and white matter lesions can be relatively characteristic in imaging. In terms of electrophysiology, slowed activity and generalized discharge are more common. DRPLA patients are easy to be misdiagnosed in clinical practice and genetic confirmation helps confirm the diagnosis.

Objective:To evaluate the efficacy and safety of endoscopic variceal ligation (EVL) of esophageal varices combined with endoscopic variceal intensive ligation (EVIL) of gastric varices for gastroesophageal variceal bleeding with liver cirrhosis under non-emergency settings.Methods:Data of 643 consecutive patients with gastroesophageal variceal bleeding due to liver cirrhosis admitted to the Department of Gastroenterology, Henan Provincial People's Hospital from January 2017 to March 2023 were included in the retrospective study. A total of 192 patients were included after excluding 451 patients. One hundred and forty-nine patients who underwent EVL of esophageal varices combined with EVIL of gastric varices were enrolled into the EVIL group, while 43 patients who underwent EVL of esophageal varices combined with endoscopic tissue adhesive injection (ETAI) of gastric varices were enrolled into the ETAI group. The endoscopic treatment success rate, esophageal variceal ligations number, operation time of endoscopic treatment, hospitalization time, rebleeding rate, mortality and the incidence of adverse events were compared between the two groups.Results:Compared with the ETAI group, the EVIL group exhibited significantly higher endoscopic treatment success rate [100.0% (149/149) VS 95.3% (41/43), P=0.049], slightly greater esophageal variceal ligations number [8 (6, 11) rings VS 7 (6, 9) rings, Z=-1.29, P=0.196], shorter operation time of endoscopic treatment [27.0 (20.5, 34.0) min VS 36.0 (21.0, 51.0) min, Z=-2.30, P=0.021], and significantly shorter hospitalization time [10 (7, 13) d VS 13 (9, 15) d, Z=-3.02, P=0.003]. The rebleeding rate within 24, 72, 120 hours after the operation, early, delayed and total rebleeding in the EVIL group were 0.0% (0/149), 0.0% (0/149), 0.7% (1/149), 2.0% (3/149), 12.8% (19/149) and 14.8% (22/149) respectively, and 4.7% (2/43) ( P=0.049), 9.3% (4/43) ( P=0.002), 9.3% (4/43) ( χ2=6.69, P=0.010), 4.7% (2/43) ( χ2=0.17, P=0.679), 30.2% (13/43) ( χ2=7.34, P=0.007) and 44.2% (19/43) ( χ2=17.20, P<0.001) in the ETAI group, respectively. No death related to rebleeding occurred within 6 weeks after the operation in 2 groups. The mortality related to rebleeding within 1 year after the operation and during the follow-up period in the EVIL group were 1.3% (2/149) and 3.4% (5/149) respectively, and 0.0% (0/43) ( P=1.000) and 2.3% (1/43) ( χ2=0.02, P=0.876) in the ETAI group, respectively. The incidences of fever, chest pain, nausea or vomiting in the EVIL group were 12.1% (18/149), 14.1% (21/149) and 13.4% (20/149) respectively, and 11.6% (5/43) ( χ2=0.01, P=0.936), 16.3% (7/43) ( χ2=0.13, P=0.721) and 18.6% (8/43) ( χ2=0.72, P=0.396) in the ETAI group, respectively. Two patients (1.3%) in the EVIL group had gastric variceal ring loss. Ectopic embolism occurred in 1 patient (2.3%) in the ETAI group. Conclusion:For patients with gastroesophageal variceal bleeding due to liver cirrhosis who are suitable for non-emergency endoscopic treatment, EVL of esophageal varices combined with EVIL of gastric varices is also safe, and more effective than EVL of esophageal varices combined with ETAI of gastric varices. This approach offers improved treatment success rate, reduced operation and hospitalization time, lower rebleeding rates, and decreased rebleeding-related mortality.

Objective To investigate the characteristics of intestinal flora and its correlation with peripheral blood microinflammatory factors in patients with pulmonary tuberculosis complicated with diabetes mellitus(PTB-DM).Methods A total of 162 patients with PTB-DM admitted to the hospital from September 2022 to September 2024 were selected as the PTB-DM group,and another 150 healthy subjects who underwent physi-cal examinations during the same period in the hospital were selected as the control group.The clinical data of all research subjects was collected.The composition of intestinal flora of the research subjects was analyzed by using 16S rRNA gene sequencing technology.The levels of peripheral blood microinflammatory factors[inter-feron-γ(IFN-γ),interleukin-6(IL-6),and tumor necrosis factor-α(TNF-α)]in all research subjects were detected.The clinical data,composition of intestinal flora and levels of microinflammatory factors of the PTB-DM group were compared with those of the control group.Spearman correlation analysis was used to analyze the correlation between the relative abundance of intestinal flora and the levels of peripheral blood microin-flammatory factors in patients with PTB-DM.Results The relative abundances of Bacteroidales and Clostridi-ales in the PTB-DM group were significantly lower than those in the control group,while the relative abun-dances of Enterobacterales and Actinobacteriales were significantly higher than those in the control group,and the differences were statistically significant(P<0.05).The levels of IFN-γ,IL-6 and TNF-α in the PTB-DM group were significantly higher than those in the control group,and the differences were statistically signifi-cant(P<0.05).The relative abundances of Bacteroidales and Clostridiales in the PTB-DM group were nega-tively correlated with the levels of IFN-γ,IL-6 and TNF-α.The relative abundances of Enterobacterales and Actinobacteriales were positively correlated with the levels of IFN-γ,IL-6 and TNF-α(all P<0.05).Conclu-sion There is a significant imbalance of intestinal flora in patients with PTB-DM,and the levels of microin-flammatory factors IFN-γ,IL-6 and TNF-α in peripheral blood are significantly increased,and are closely re-lated to the relative abundance of specific flora.

Split liver transplantation(SLT)has become an indispensable method for expanding the donor liver pool.However,advanced age in recipients can have significant adverse effects on prognosis.We report the case of an 82-year-old man with chronic liver failure and polycystic liver disease who underwent in vivo split right triple lobe donor liver transplantation on October 29,2021.The patient made a remarkable recovery and was discharged 1 month after surgery.To date,he has been followed up for 32 months,with favorable laboratory and imaging test results,and no significant abnormalities or complications.Currently,this patient may be the oldest SLT recipient in the world.With comprehensive preoperative evaluation,optimized surgical techniques,and individually tailored postoperative care,older adults can safely undergo SLT.Therefore,advanced age should not be considered an absolute contraindication for this procedure.

Objective: To evaluate the platelet transfusion requirements in children with high-risk stage Ⅳ neuroblastoma undergoing autologous hematopoietic stem cell transplantation (ASCT), and to identify risk factors for increased transfusion needs and prolonged time to platelet transfusion independence. Methods: This single-center retrospective clinical study included 96 children with high-risk stage Ⅳ neuroblastoma who underwent ASCT from January 2019 to May 2024 in our hospital. Relevant clinical data were collected and analyzed, including age, gender, body surface area, platelet count (PLT) on stem cell infusion day (day 0), conditioning regimen, CD34 stem cell dose, platelet transfusion requirements during transplantation, and time to platelet transfusion independence post-transplant. Results: All 96 (100%) children received transfusion after ASCT. From day 0 to transfusion independence, the median number of platelet transfusion was 3 (2, 4.50), and the median volume of platelet transfused was 3 (2, 4.25) units. Platelet transfusion was required in almost all children in pseudo-healing stage (day 4 to day 6) and polar stage (day 7 to day 14), with transfusion rates as high as 83.33%(n=80) and 100%(n=96), respectively. The median time to platelet transfusion independence post-transplant was 13(11,17) days. Multivariate analysis showed that PLT<100×10 /L on day 0, platelet transfusion within one week before ASCT, the use of “busulfan+ melphalan” conditioning regimen, and CD34 stem cell dose<4.0×10 /kg were associated with significantly increased platelet requirements and numbers of transfusion (P<0.05). PLT<100×10 /L on day 0, platelet transfusion within one week before ASCT, and CD34 stem cell dose<4.0×10 /kg were associated with significantly delayed platelet transfusion independence (P<0.05). Age, sex, and blood type showed no statistically significant association (P>0.05) with post-transplant platelet transfusion requirements or time to transfusion independence in neuroblastoma patients. Conclusion: This study provided quantitative data for platelet transfusion after ASCT in children with high-risk stage Ⅳ neuroblastoma, and identified PLT<100×10 /L on day 0, platelet transfusion within one week before ASCT, CD34 stem cell dose<4.0×10 /kg were risk factors for increased platelet transfusions and delayed transfusion independence. Furthermore, the use of the BuMel (busulfan-melphalan) conditioning regimen was also found to contribute to increased transfusion requirements.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Objective To establish a rat model of ovarian endometriosis(EMS)using the horn reversion method,to provide an ideal animal model for exploring the pathogenesis and treatment of EMS.Methods Fifty SPF-grade female SD rats were divided randomly into five groups:a sham group,and 1,2,3,and 4 weeks after surgery groups,respectively(n=10 rats per group).Apart from the sham group,an ovarian-type EMS model was established in the other groups by the uterine horn refracture method,and the modeling success rate,and ectopic foci volume and mass were observed in each group.The morphology of ectopic foci was observed by hematoxylin-eosin(HE),and expression of proliferating cell nuclear antigen(PCNA),Ki67,epithelial cadherin(E-cadherin),and neural cadherin(N-cadherin)in the uterus and ectopic foci tissues were detected by immunohistochemistry.The model was further evaluated and the degree of cell proliferation and epithelial mesenchymal transformation at different times after modeling were analyzed.Results The modeling success rates in the 1,2,3,and 4 weeks after surgery groups were 80%,90%,100%,and 100%,respectively(P＞0.05).The volume and mass of the ectopic foci were significantly greater in the 3 and 4 weeks after surgery groups compared with the 1 and 2 weeks after surgery groups(P＜0.01).HE staining showed endometrial epithelial cells,mesenchymal cells and a few glands in the ectopic foci tissues.Immunohistochemical staining showed that expression levels of Ki67,PCNA,and N-cadherin in uterus tissues were significantly higher(P＜0.05,P＜0.01)in all the model groups compared with the sham group,while expression levels of E-cadherin were significantly lower(P＜0.05,P＜0.01).Expression levels of Ki67,PCNA,and N-cadherin in the uterus and ectopic foci tissues were significantly higher(P＜0.05,P＜0.01)in the 2,3,and 4 weeks after surgery groups compared with the 1 week after surgery group,while expression levels of E-cadherin were significantly lower(P＜0.05,P＜0.01).Conclusion The uterine horn reversion method can be used to establish an ovarian EMS model in rats.Ectopic lesions can be observed 1 week after surgery.The success rate of modeling increases with modeling time,stabilizing at 3 weeks postoperatively.Ki67,PCNA,and N-cadherin were significantly expressed in the uterus and ectopic foci tissues,and their expression levels increased with modeling time,while E-cadherin expression in the uterus and ectopic foci tissues decreased with modeling time.These results showed good modeling success of the EMS rat model,suggesting that it could be used as a stable EMS modeling method.
