Network pharmacology has gained widespread application in drug discovery, particularly in traditional Chinese medicine (TCM) research, which is characterized by its "multi-component, multi-target, and multi-pathway" nature. Through the integration of network biology, TCM network pharmacology enables systematic evaluation of therapeutic efficacy and detailed elucidation of action mechanisms, establishing a novel research paradigm for TCM modernization. The rapid advancement of machine learning, particularly revolutionary deep learning methods, has substantially enhanced artificial intelligence (AI) technology, offering significant potential to advance TCM network pharmacology research. This paper describes the methodology of TCM network pharmacology, encompassing ingredient identification, network construction, network analysis, and experimental validation. Furthermore, it summarizes key strategies for constructing various networks and analyzing constructed networks using AI methods. Finally, it addresses challenges and future directions regarding cell-cell communication (CCC)-based network construction, analysis, and validation, providing valuable insights for TCM network pharmacology.

Objective:To investigate the application value of intraoperative electrocochleography（ECochG） monitoring technique and insertion techniques in cochlear implant（CI） and analyze its relationship with postoperative residual hearing（RH） preservation. Methods:Thirty-one patients（35 ears） who received CI in our hospital from June 2022 to July 2024 were enrolled. The Advanced Bionics Active Insertion Monitoring（AIM） system was used for real-time ECochG monitoring during surgery. Intraoperative cochlear microphonics （CM） waveform changes were recorded and analyzed in relation to postoperative RH preservation. Results:①ECochG recordings were successfully obtained in 34 of 35 ears （97.1%）. ②According to Harris classification, there were 7 ears（20.6%） of Type A（rising）, 7 ears（20.6%） of Type C（declining）, 8 ears（23.5%） of Type CC（fluctuating）, and 12 ears（35.3%） of Type D（no response）. ③The total CM amplitude decrease was significantly moderately correlated with postoperative low-mid frequency hearing loss（r=0.67, P=0.017）. The total CM amplitude decrease was significantly moderately correlated with postoperative low frequency hearing loss（r=0.65, P=0.023）. ④For the mean amplitude variation, the Amax was 30.70 μV, the Amin was 8.64 μV, and the Aend was 18.27 μV. ⑤Sixteen cases completed postoperative follow-up, with an average low-mid frequency（125-1 000 Hz） residual hearing loss of 15.25 dB HL and a RH preservation rate of 87.5%. Conclusion:Intraoperative ECochG monitoring can effectively predict postoperative residual hearing changes, effectively guide surgical manipulation, and improve residual hearing preservation rate.

Objective To investigate the effect of β-arrestin1(ARRB1)on cell proliferation,migration and invasion in oral squamous cell carcinoma(OSCC).Methods Based on The Cancer Genome Atlas(TCGA)database,the expression profiles of ARRB1 in OSCC were analyzed,and then Gene Set Enrichment Analysis(GSEA)was used to suggest the possible signaling pathways involved,and to explore its potential impact on the prognosis of OSCC patients.Immuinohistochemistry(IHC)was performed to detect the expression of ARRB1 in OSCC tumor tissues and adjacent tissues,and the correlation between ARRB1 expression and clinicopathological features was statistically analyzed.The expression profiles of ARRB1 in SCC-15,CAL-27 and HOK cell lines were verified by qPCR and Western blotting.The ARRB1 overexpression plasmid model was constructed,and its effects on the proliferation,migration and invasion of OSCC cells were analyzed by clone formation,EdU,scratch and Transwell assays.Results TCGA showed that the expression level of ARRB1 was significantly lower in head and neck squamous cell carcinoma(HNSC)and OSCC tissues than the corresponding normal tissues(P<0.01).The expression of ARRB1 in OSCC tissues was correlated with tumor differentiation,lymph node metastasis and TNM stage(P<0.05).The OSCC patients with high expression of ARRB1 had a lower survival rate than those with low expression(P<0.01),which was consistent with the results of bioinformatics analysis.The expression level of ARRB1 in SCC-15 and CAL-27 cells was lower than that of HOK cells(P<0.01),and its overexpression significantly inhibited cell proliferation(P<0.05),migration(P<0.01)and invasion(P<0.01).Conclusion ARRB1 is lowly expressed in OSCC,its overexpression inhibits the proliferation,migration and invasion of OSCC cells,and it is related to prognosis improvement.

OBJECTIVE To investigate the relationship between azimuth direction,angular intervals,and the accuracy of azimuthal sound source localization.METHODS Fifteen young subjects with normal hearing were tested using nine azimuth settings.The test results were presented as root mean square error and percentage confusion.RESULTS The confusion rate under high-frequency narrowband noise was significantly higher than that under broadband noise and three-syllable words.In the frontal direction,statistically significant differences were observed between the 20° and 10° intervals,as well as between the 20° and 15° intervals(P<0.05),but no significant difference was found between the 10° and 15° intervals(P>0.05).In the lateral and rear directions,statistically significant differences were found between the 30° and 15° intervals,as well as between the 30° and 20° intervals(P<0.05),but no significant difference was found between the 15° and 20° intervals(P>0.05).Statistically significant differences were observed between the frontal direction and both the lateral and rear directions(P<0.05),but no significant difference was found between the lateral and rear directions(P>0.05).CONCLUSION Using stimuli that contain broader bandwidth cues can more accurately reflect the subject's horizontal localization ability.For source azimuth identification tests using broadband noise and three-syllable words,it is recommended to use a 15° interval in the frontal direction,and a 20° interval in the lateral and rear directions.The frontal and lateral directions can be preferred for testing.

Objective:To systematically evaluate the global disease burden of neonatal sepsis and other neonatal infections（NSNIs），providing scientific basis for their prevention and control.Methods:Using the Global Burden of Disease（GBD）2021 database，this article calculated the incidence，mortality，and age-standardized rates for NSNIs. Trends were evaluated with Joinpoint regression model，and compared at different socio-demographic index（SDI）levels.Results:From 1990 to 2021，the global age-standardized incidence rate（ASIR）of NSNIs decreased from 78.98 to 62.70 per 100 000 with an with average annual percentage change（AAPC）of -0.73%（ P<0.01）. The age-standardized mortality rate（ASMR）declined from 4.77 to 3.76 per 100 000 with an AAPC of -0.76%（ P<0.01）. In particular，the disease burden was consistently higher among male neonates. Low birth weight was the primary risk factor globally，followed by preterm birth. Regions with lower SDI levels exhibited higher ASIR and ASMR，and household solid fuel air pollution contributed more to NSNIs-related mortality. Conclusion:Although the overall disease burden of NSNIs has declined，male neonates and low-SDI regions still face substantial challenges. Continuous efforts to improve air quality are warranted，and low-SDI regions should further strengthen healthcare infrastructure to enhance diagnostic and treatment quality.

Telesurgery is a novel way to implement long-distance surgery by using communication technology and robotic system. In recent years, with the development and improvement of communication technology and domestic robotic surgery systems, telesurgery has developed rapidly in China, and has been applied in urology, hepatobiliary surgery, orthopedics and other fields. However, there are few reports in the field of gastrointestinal surgery. Based on the previous practice of remote gastrointestinal surgery between Beijing and Sanya, we review and elaborate on the application status and development prospects of telesurgery in the field of gastrointestinal surgery.

BACKGROUND:Based on the concept of the combination of medicine and industry and the advantages of traditional Chinese medicine treatment,the construction of a new composite material loaded with the effective active ingredient of traditional Chinese medicine is a hot research spot in the repair of spinal cord injury,and is expected to become an effective means to solve this problem. OBJECTIVE:To observe the effect of supramolecular conducting hydrogel carrying ligustrazine in repairing spinal cord injury in rats. METHODS:The supramolecular conducting hydrogel carrying ligustrazine was prepared and its microstructure,conductivity,rheology,swelling rate and in vitro release performance were characterized.45 SD rats were divided into 3 groups by random number table method,with 15 rats in each group:no spinal cord injury in the sham operation group;spinal cord injury model was established in the model group;and supramolecular conducting hydrogel carrying ligustrazine was injected into the spinal cord injury area after model establishment in hydrogel group.BBB score was used to evaluate the recovery of hind limb motor function of each group before and 1,7,14,21 and 28 days after modeling,respectively.28 days after the model establishment,the spinal cord tissues were collected and analyzed by hematoxylin-eosin staining,immunohistochemical staining and western blot assay. RESULTS AND CONCLUSION:(1)Under scanning electron microscopy,the supramolecular conducting hydrogel with ligustrazine displayed a three-dimensional micrometer-scale porous network structure with high porosity and a pore size of approximately 100 μm.The conductivity of the hydrogel was 7.66 S/m;the swelling rate was 3 764.42%,and it had certain mechanical stability and injection property.In vitro sustained release experiments demonstrated that the supramolecular conducting hydrogel with ligustrazine sustainably released ligustrazine for more than 800 hours.With the extension of time,the cumulative release of ligustrazine exhibited an increasing trend.(2)With the extension of modeling time,the hind limb motor function gradually recovered in the model group and the hydrogel group,and the hind limb motor function of the hydrogel group was better than that of the model group on 14,21,and 28 days after modeling(P<0.05).Hematoxylin-eosin staining demonstrated that the spinal cord tissue of the model group had cavities and a large number of inflammatory cells could be seen at the stump.In the hydrogel group,some inflammatory cells were infiltrated in the injured area of the spinal cord;the void area of the injured area was reduced;neuron cells appeared in the junction area,and the tissue arrangement was relatively neat.Immunohistochemical staining and western blot assay exhibited that the expression of tumor necrosis factor α and interleukin-6 protein in the rat spinal cord of the hydrogel group was lower than that in the model group(P<0.05),and the expression of neuronal nuclear antigen protein was higher than that in the model group(P<0.05).(3)These findings confirm that the supramolecular conducting hydrogel carrying ligustrazine can promote the repair of spinal cord injury.

GPCRs are the largest membrane protein receptor superfamily in the human body, with more than 800 isoforms, and approximately 35% of Food and Drug Administration-approved and marketed drugs currently target GPCRs for the treatment of a wide range of diseases, for heart failure (beta-adrenergic receptors), peptic ulcer (histamine receptors), prostate cancer (gonadotropin receptors), hypertension (adrenergic and angiotensin receptors), pain (opioid receptors), and bronchial asthma (beta2-adrenergic receptors) examples. Although the number of GPCRs is enormous, the signaling proteins downstream of them are limited, heterotrimeric G proteins (GPs) are key proteins that signal GPCRs, translate extracellular stimuli into intracellular responses by coupling to GPCRs and initiate multiple signaling events via downstream cascades. Podocytes are an important component of the glomerular filtration barrier, and their damage is a central event in proteinuria formation and progressive glomerulosclerosis. This article reviews the regulation of GPs, their signaling and their role in podocyte injury to provide a theoretical basis for scientific research and clinical treatment of this disease.
