This paper outlines the development of artificial intelligence （AI） and its applications in traditional Chinese medicine （TCM） research， and elucidates the roles and advantages of large language models， knowledge graphs， and natural language processing in advancing syndrome identification， prescription generation， and mechanism exploration. Using spleen-stomach diseases as an example， it demonstrates the empowering effects of AI in classical literature mining， precise clinical syndrome differentiation， efficacy and safety prediction， and intelligent education， highlighting an upgraded research paradigm that evolves from data-driven and knowledge-driven approaches to intelligence-driven models. To address challenges related to privacy protection and regulatory compliance in cross-institutional data collaboration， a "trusted federated evidence-based analysis platform for TCM spleen-stomach diseases" is proposed， integrating blockchain-based smart contracts， federated learning， and secure multi-party computation. The deep integration of AI with privacy-preserving computing is reshaping research and clinical practice in TCM spleen-stomach diseases， providing feasible pathways and a technical framework for building a high-quality， trustworthy TCM big-data ecosystem and achieving precision syndrome differentiation.

Objectives: . This study aimed to investigate the regulatory functions of gamma-aminobutyric acid (GABA)ergic neural circuits from the inferior colliculus (IC) to the medial geniculate body (MGB) in salicylate-induced tinnitus. Methods: . Mice were treated with salicylate to induce tinnitus, and tinnitus-like behaviors were evaluated via gap prepulse inhibition of acoustic startle. Using combined viral tracing methodologies, we identified and mapped the pathways and connections from the IC to the MGB. Furthermore, we employed Gq-coupled human M3 designer receptors exclusively activated by designer drugs (DREADDs) and Gi-coupled human M4 DREADDs to achieve targeted excitation or suppression of GABAergic neurons in the IC and MGB. Following the administration of clozapine N-oxide, which binds to these receptors, we modulated these neural circuits to assess their impact on tinnitus severity in a mouse model. Results: . Our findings demonstrated that mice exposed to salicylate exhibited tinnitus-like behaviors. GABAergic neurons projecting retrogradely from the MGB to the IC were primarily concentrated in the external nucleus of the IC. After clozapine N-oxide administration, chemogenetic activation of IC-MGB GABAergic neurons aggravated salicylate-induced tinnitus. Additionally, activation of GABAergic neurons between the IC and MGB induced the perception of tinnitus even without salicylate. However, chemogenetic inhibition of the IC-MGB GABAergic circuit did not reverse salicylate-induced tinnitus. Conclusion . These findings suggest that activation of the IC-MGB GABAergic neural circuit may contribute to tinnitus generation through a mechanism distinct from that of salicylate-induced tinnitus. This study provides novel insights into the mechanisms underlying tinnitus.

Objective The aim of the study is to analyze the incidence patterns and epidemiological characteristics of parasitic and vector-borne diseases in the Minhang and Jinshan districts of Shanghai, and provide evidence-based information for optimizing prevention and control measures. Methods We collected information from epidemic reports and epidemiological investigation forms for cases of parasitic and vector-borne diseases from 2005 to 2024 in Shanghai's Minhang and Jinshan districts. Descriptive epidemiological method were adopted to conduct a comparative analysis of incidence trends, epidemic characteristics, and infection sources. Results A total of 229 cases in 7 categories were reported between 2005 and 2024, with an average annual incidence rate of 0.36/100 000. The average annual incidence rate in Minhang District was significantly higher than that in Jinshan District. The most prevalent diseases were malaria and dengue fever, followed by Japanese encephalitis. Monthly case reports were available, predominantly from June to October, with a peak in July-August. A statistically significant difference was observed between the two districts in case distribution during June-October (P＜0.001), whereas no significant difference was found for July-August (P=0.331). The majority of cases were young men (111/229,48.47%), aged 20-39 years. Migrant workers/farmers constituted the largest occupational group (55/229, 24.02%). Registered residents of other provinces and cities (147/229,64.19%), and the main source of infection was overseas importation (112/229,48.91%). There were no statistically significant differences in gender and household-registration composition between the two districts (P＞0.05). Significant differences existed in age, occupation, and source of infection (P＜0.05). The imported diseases were malaria and dengue fever, with Africa and Southeast Asia being the primary source locations. Malaria was the predominant disease imported from other provinces and cities, with cases having been imported from abroad since 2012. Local infections were mainly Japanese encephalitis, followed by malaria (with the last local case reported in 2010). Cases between 2005 and 2009 were predominantly imported from other provinces and cities. The proportion of cases imported from abroad increased sharply after 2010, particularly in Minhang District. Local infections sometimes arise in Jinshan District, with Japanese encephalitis serving as the primary type. Conclusions Incidence rates of parasitic and vector-borne diseases in Minhang and Jinshan districts have generally remained low. To further reduce this disease burden, it will be necessary to strengthen joint measures for prevention and control, eliminate the environmental risk factors of vector organisms, enhance monitoring and precise control of the environment and inbound personnel to prevent the occurrence and transmission of parasitic and vector-borne diseases.

Objective To explore the clinical efficacy of wrist arthroscopy assisted closed reduction with external fixation in the treatment of intra-articular comminuted fractures of the distal radius(type C3).Methods A retrospective analysis was conducted on 98 patients with type C3 intra-articular comminuted fractures of the distal radius admitted to our hospital from March 2022 to February 2023.Among them,48 patients underwent wrist arthroscopy assisted closed reduction with external fixation with a bracket(arthroscopy group),and another 50 patients underwent open reduction with steel plate internal fixation surgery(control group).The two groups were compared in terms of operation time,intraoperative bleeding volume,incision length,fracture union time,range of motion(ROM)of joint,Visual Analogue Scale(VAS),and Gartland-Werley wrist scores,as well as radiographic parameters(palmar tilt,ulnar inclination,and radial height)evaluated at various follow-up intervals.Results The arthroscopy group had an operation time of(55.3±10.5)min,which was significantly shorter than that in the control group[(83.4±14.6)min;t=-10.979,P=0.000].The intraoperative bleeding volume in the arthroscopy group was(42.3±8.6)ml,which was less than that in the control group[(71.4±10.5)ml;t=-14.953,P=0.000].The incision length of the arthroscopy group was(1.3±0.3)cm,which was shorter than that of the control group[(5.1±1.5)cm;t=-18.550,P=0.000].The arthroscopy group had a fracture healing time of(10.7±1.4)weeks,which was shorter than that in the control group[(12.2±1.6)weeks;t=-4.855,P=0.000].The palmar flexion ROM in the arthroscopy group was 68.8°±8.3°,which was significantly higher than that in the control group(61.5°±9.4°;t=4.002,P=0.000).The dorsiflexion ROM in the arthroscopy group was 63.9°±7.5°,which was significantly higher than that in the comtrol group(59.2°±8.3°;t=2.931,P=0.004).The pronation ROM in the arthroscopy group was 67.4°±10.3°,which was significantly higher than that in the control group(62.1°±9.9°;t=2.604,P=0.011).The supination ROM in the arthroscopy group was 70.5°±7.4°,which was significantly higher than that in the control group(64.4°±8.6°;t=3.777,P=0.000).The VAS score of the arthroscopy group was(1.3±0.6)points,which was significantly lower than that in the control group[(1.7±0.5)points;t=-3.941,P=0.000].After 6 months,the Gartland-Werley wrist scores of the arthroscopy group was significantly higher than that of the control group(Z=-2.614,P=0.009).The wrist joint imaging showed significantly higher radial height,palmar inclination angle,and ulnar deviation angle in the arthroscopy group than the control group(all P=0.000),while there were no significant differences in palmar inclination angle and ulnar deviation angle at different time points within each group(P＞0.05).Except for significant differences in radial height at 3 d,1 month,and 6 months after surgery(P=0.015,P=0.035),there were no significant differences between any other time points(P＞0.05).The interaction between time and group was not significant for palm inclination angle,ulnar deviation angle,and radial height(P＞0.05).Conclusion Wrist arthroscopy assisted closed reduction with external fixation for intra-articular comminuted fractures of distal radius has advantages of short operation time,less intraoperative blood loss,and good recovery of wrist joint functions.

Objective:To establish 30-day of age transcutaneous bilirubin (TcB) reference curves for healthy neonates, and to investigate regional variations in bilirubin dynamics.Methods:A multicenter retrospective cohort study was conducted. A total of 220 950 healthy neonates born at a gestational age of 35-<42 weeks, with a birth weight ≥2 000 g, who did not receive phototherapy within 60 h after birth were recruited. All of them underwent remote TcB monitoring using the Bilibaby remote jaundice monitoring system between August 1 st, 2020 and December 31 st, 2024 in 426 hospitals. TcB data were collected within the period from birth to 30-day of age. The P40, P75, and P95 of TcB values were calculated, and dynamic TcB curves for 30-day of age were constructed. Patterns of bilirubin change, rates of change, and transition outcomes were described. Regional comparisons between South and North were conducted using linear mixed-effects models for TcB trajectories and Pearson′s chi-square test for outcome differences. Results:A total of 220 950 neonates were included, of whom 101 711 (46.03%) were female. Gestational age at birth was (38.75±1.12) weeks, and birth weight was (3 272±417) g. TcB levels increased rapidly within 3-day of age, peaked at 4-6-day of age, with peak values at P40, P75, and P95 of 200.6, 239.7 and 275.4 μmol/L (11.8, 14.1 and 16.2 mg/dl), respectively. TcB levels gradually declined thereafter and stabilized after 13-day of age, with values at P40, P75, and P95 fluctuating between 147.9-159.8, 190.4-200.6, and 231.2-239.7 μmol/L (8.7-9.4, 11.2-11.8, 13.6-14.1 mg/dl), respectively. Notably, among neonates categorized as low-or low-intermediate-risk within 3-day of age, 6 700 (12.76%) progressed to intermediate-high or high risk between 4 and 30 days of age. Before 13-day of age, TcB levels in the southern regions were consistently higher than those in the northern regions ( P=0.039); from 14 to 30 days of age, the overall TcB levels had no statistically difference, but the temporal changes in TcB still showed regional differences (degrees of freedom=3, all interaction P<0.05). Among neonates classified as low-or low-intermediate risk within 3-day of age, 25 326 were from southern regions, of whom 4 254 (16.80%) progressed to intermediate-high or high risk between 4 and 30 days of age. In northern regions, 27 193 neonates were classified as low-or low-intermediate risk within 3-day of age, among whom 2 446 (8.99%) progressed to intermediate-high or high risk. The risk progression between the 2 regions had statistically difference ( χ2=716.49, P<0.001). Conclusions:A TcB percentile curve for neonates within 30-day of age was established, revealing that both the overall TcB level and its temporal trend were higher in southern than in northern newborns. These findings provide baseline data to support continuous management of neonatal jaundice.

Objective:To explore the application value of cinematic rendering reconstruction technology in laparoscopic resection of giant adrenal tumors.Methods:As many as 21 patients with large adrenal tumors who underwent laparoscopic resection in Yongchuan Hospital Affiliated to Chongqing Medical University from January 2021 to January 2024 were retrospectively analyzed, with a median age of 54.0 (40.5, 58.0) years and a median tumor diameter of 7.3 (6.8, 8.8) cm. All patients underwent preoperative cinematic rendering 3D reconstruction imaging. All patients underwent enhanced CT scans. Their CT images were three-dimensionally reconstructed on the post-processing workstation platform. By changing image perspectives, adjusting the visualization of organs or blood vessels, and using physical volume rendering, real-shadow-rendered images were obtained. With these images, surgeons can intuitively understand important preoperative information, like the relationship between the tumor and surrounding organs and the path of tumor-feeding blood vessels, for preoperative planning. Following thorough preoperative preparation, laparoscopic transabdominal resection was performed. During surgery, 20 tumors were found to be located in the adrenal gland, and 1 in the retroperitoneum, with 13 on the left side and 8 on the right side. Preoperative cinematic rendering 3D imaging was consistent with intraoperative findings.Results:All 21 patients underwent successful surgeries, with an average operation time of (199.0±95.3) minutes, a median blood loss of 220 (150, 500) ml, and a median blood transfusion volume of 200 (150, 400) ml. No significant damage of vital organs or major blood vessels occurred, and there were no case of conversion to open surgery.Conclusions:For retroperitoneal giant adrenal tumors, utilizing cinematic rendering 3D reconstruction imaging enables a comprehensive understanding of the relationship between the tumor and surrounding organs and vessels preoperatively. This approach can reduce intraoperative bleeding and collateral injuries, improve the success rate of laparoscopic resection, and enhance overall surgical safety.

Objective:To investigate microstructural alterations in the optic chiasm and optic radiations of multiple sclerosis (MS) and neuromyelitis optica spectrum disorders (NMOSD) based on diffusion kurtosis imaging (DKI).Methods:This study was a cross-sectional study. Retrospective analyses were conducted on the clinical and imaging data of 63 patients with relapsing-remitting MS (RRMS) and 62 patients with NMOSD diagnosed at First Affiliated Hospital of Chongqing Medical University from January 2019 to December 2023. According to the occurrence of optic neuritis (ON), they were categorized into ON-positive MS (ON+MS) group (40 cases), ON-negative MS (ON-MS) group (23 cases), ON-positive NMOSD (ON+NMOSD) group (40 cases) and ON-negative NMOSD (ON-NMOSD) group (22 cases). In addition, 40 healthy controls were enrolled during the same period. DKI data of all subjects were collected, and DKI post-processing was performed to obtain fractional anisotropy (FA), mean kurtosis (MK), axial kurtosis (AK), and radial kurtosis (RK) values of the optic chiasm and bilateral optic radiations. The scores of the mini-mental state examination (MMSE), montreal cognitive assessment (MoCA), and expanded disability status scale (EDSS) were obtained. The Kruskal-Wallis test was used to analyze the differences in DKI parameters of the optic chiasm and bilateral optic radiation among the 5 groups, and the Holm-Bonferroni method was employed for multiple comparison correction in pairwise comparisons.Results:There were statistically significant overall differences in the DKI parameters of the optic chiasm and bilateral optic radiations among healthy control group, ON+MS group, ON-MS group, ON+NMOSD group, and ON-NMOSD group (all P0.05). The FA value of the optic chiasm in ON+NMOSD group was significantly lower than that of healthy control group and ON-MS group, as well as ON-NMOSD group ( P0.05). The FA value of the left optic radiation in ON+NMOSD group was lower than that in healthy control group and the ON-MS group. The RK value of the optic chiasm in ON+MS group was lower than that in the healthy control group and ON-NMOSD group ( P0.05). The MK and RK values of the left optic radiation in ON-MS group were significantly lower than those in the ON+NMOSD group and ON-NMOSD group ( P0.05). Conclusions:NMOSD and RRMS patients demonstrate varying degrees of microstructural damage in the optic chiasm and optic radiations. Differences of DKI parameters suggest different pathological mechanisms of visual pathway damage between NMOSD and MS, which may be helpful for early detection of occult visual pathway lesions.

Objective To compare the changes of lung cell pyroptosis indexes in heat stress rats through different target temperature cooling intervention on classical heat stroke(CHS)rats,and to explore the choice of suitable target temperature of CHS.Methods A total of 40 male SD rats were divided into the blank control group(n=10)and classical heat stroke(CHS,n=30)group according to the random number table method.The CHS group was divided into the CHS0 group(Tic),CHS1 group(Tic-1℃)and CHS2 group(Tic+1℃)according to the initial core temperature(Tic)±1℃.After anesthesia,the rats in CHS group were placed by the prone position in the thermal environment simulation chamber,and the heat shock rat model was established when the core body temperature reached 42℃.Immediately after successful model-ing,the room temperature water bath was used to cool down to the setting target temperature of the group,and then the cooling blanket was used to maintain the body temperature for 3 h.The blank control group was always kept at room temperature.At the end of the experiment,the blood samples of femoral artery of rats were collected,and the levels of serum interleukin-1β(IL-1β)and interleukin-18(IL-18)were detected by ELISA.The lung samples of rats were taken to prepare the tissue homogenate.Then the concentrations of IL-1β and IL-18 in the lung tissue were detected by ELISA and Western blot method was used to detect GSDMD and cysteine aspartate protease-1 precursor(pro-caspase-1)protein expression levels in rat lung tissue,and the enzyme activity in the sample was calculated according to the formula or standard curve.Results The levels of IL-1β and IL-18 in lung tissues and serum in the CHS0 group and serum IL-18 level in the CHS1 group were higher than those in the blank control group(P<0.05).The lung tissue IL-1β level in the CHS1 group,the IL-1β and IL-18 levels in the CHS2 group,and the IL-18 level in the serum CHS1 and CHS2 groups were lower than those in the CHS0 group.There was no statistically significant difference between the CHS1 group and CHS2 group.The GSDMD and pro-caspase-1 levels in the CHS0 group and CHS2 group,and the GSDMD level in the CHS1 group were higher than those in the blank control group(P<0.05).The GSDMD and pro-caspase-1 levels in the CHS1 group and CHS2 group were lower than those in the CHS0 group,and the pro-caspase-1 level in the CHS1 group was lower than that in the CHS2 group.Conclusion The expression levels of lung pyroptosis effective molecules and proteins in lung cells of heat stress rats are increased,and the cool-ing intervention could alleviate the lung tissue cellular pyroptosis.A cooling intervention setting the target temperature to a certain range above or below the initial core temperature may have a better protective effect on the lung tissue of heat stress rats.
