Pharmacotranscriptomic profiles, which capture drug-induced changes in gene expression, offer vast potential for computational drug discovery and are widely used in modern medicine. However, current computational approaches neglected the associations within gene‒gene functional networks and unrevealed the systematic relationship between drug efficacy and the reversal effect. Here, we developed a new genome-scale functional module (GSFM) transformation framework to quantitatively evaluate drug efficacy for in silico drug discovery. GSFM employs four biologically interpretable quantifiers: GSFM_Up, GSFM_Down, GSFM_ssGSEA, and GSFM_TF to comprehensively evaluate the multi-dimension activities of each functional module (FM) at gene-level, pathway-level, and transcriptional regulatory network-level. Through a data transformation strategy, GSFM effectively converts noisy and potentially unreliable gene expression data into a more dependable FM active matrix, significantly outperforming other methods in terms of both robustness and accuracy. Besides, we found a positive correlation between RS_GSFM and drug efficacy, suggesting that RS_GSFM could serve as representative measure of drug efficacy. Furthermore, we identified WYE-354, perhexiline, and NTNCB as candidate therapeutic agents for the treatment of breast-invasive carcinoma, lung adenocarcinoma, and castration-resistant prostate cancer, respectively. The results from in vitro and in vivo experiments have validated that all identified compounds exhibit potent anti-tumor effects, providing proof-of-concept for our computational approach.

OBJECTIVES: To investigate the risk factors of overall postoperative complications in elderly patients undergoing gastrointestinal surgeries. METHODS: This study was conducted among a total of 1388 elderly patients, who underwent elective gastrointestinal surgeries at 17 centers across China between April, 2020 and April, 2022. The primary outcome was the incidence of postoperative complications within 30 days, including procedure-related, neuropsychiatric, respiratory, cardiovascular, and gastrointestinal complications as well as acute kidney injury. Baseline characteristics, preoperative psychological and functional status, intraoperative anesthesia and surgical factors, intraoperative medication, use of nerve block, and postoperative analgesia methods were compared between the patients experiencing one or more postoperative complications and those without complications. Univariate and multivariate logistic regression analyses were performed to identify the independent risk factors for postoperative complications. The relationship between postoperative acute pain and each type of complication were explored. RESULTS: The incidence of overall postoperative complications was 50.8% (705/1388) in these patients. Multivariate analysis showed that age (OR: 1.026; 95% CI: 1.006-1.046), prognostic nutritional index (OR: 0.998; 95% CI: 0.997-1.000), preoperative EuroQol-5 dimensions score (OR: 0.094; 95% CI: 0.018-0.500), blood loss (OR: 1.002; 95% CI: 1.001-1.003), and acute postoperative pain (OR: 1.308; 95% CI: 1.033-1.657) were significantly associated with the occurrence of postoperative complications. Specifically, patients experiencing severe postoperative pain had a significantly higher incidence of neuropsychiatric (27.2% vs 19.8%), procedure-related (17.3% vs 10.2%), and cardiovascular complications (3.6% vs 1.7%). CONCLUSIONS An advanced age, a low preoperative nutritional index, a poor quality of life score, a greater volume of intraoperative blood loss, and acute postoperative pain are independent risk factors for postoperative complications in elderly patients undergoing gastrointestinal surgeries. There is a significant association between acute postoperative pain and multi-system complications.

This research study focuses on addressing the limitations of current neuropathic pain (NP) treatments by developing a novel dual-target modulator, E0199, targeting both Na_V1.7, Na_V1.8, and Na_V1.9 and K_V7 channels, a crucial regulator in controlling NP symptoms. The objective of the study was to synthesize a compound capable of modulating these channels to alleviate NP. Through an experimental design involving both in vitro and in vivo methods, E0199 was tested for its efficacy on ion channels and its therapeutic potential in a chronic constriction injury (CCI) mouse model. The results demonstrated that E0199 significantly inhibited Na_V1.7, Na_V1.8, and Na_V1.9 channels with a particularly low half maximal inhibitory concentration (IC₅₀) for Na_V1.9 by promoting sodium channel inactivation, and also effectively increased K_V7.2/7.3, K_V7.2, and K_V7.5 channels, excluding K_V7.1 by promoting potassium channel activation. This dual action significantly reduced the excitability of dorsal root ganglion neurons and alleviated pain hypersensitivity in mice at low doses, indicating a potent analgesic effect without affecting heart and skeletal muscle ion channels critically. The safety of E0199 was supported by neurobehavioral evaluations. Conclusively, E0199 represents a ground-breaking approach in NP treatment, showcasing the potential of dual-target small-molecule compounds in providing a more effective and safe therapeutic option for NP. This study introduces a promising direction for the future development of NP therapeutics.

Infectious disease is a major public health problem threatening human health and social development, and infectious disease teaching is an important part of public health education. However, traditional infectious disease teaching faces challenges such as overly theoretical and fragmented content, overly traditional and monotonous methods, and a narrow and isolated vision, which makes it difficult to adapt to the current complex and changing situation of infectious disease prevention and control. The “One Health” concept emphasizes interdisciplinary, cross-sectoral, and cross-regional communication and cooperation to achieve the harmonious unity of health for humans, animals, and the environment, which is significant in preventing and controlling infectious diseases. This paper proposes some ideas for reforming infectious disease teaching based on the One Health concept, which aims to improve the quality and effectiveness of infectious disease teaching by recognizing the close connection between human health, animal health, and environmental health. Specifically, it is suggested to reform the teaching in four aspects: introducing the basic concepts, principles, and practices of One Health, increasing the content of infectious diseases related to One Health, adopting diversified and interactive teaching methods, and establishing cross-disciplinary teaching cooperation. Concrete recommendations are provided for each aspect. This paper argues that reforming infectious disease teaching based on the One Health concept is conducive to cultivating public health talents with global vision, systems thinking, and cross-disciplinary collaboration capabilities, providing robust talent support for coping with emerging, re-emerging, and endemic infectious disease threats.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

All were males, aged 32-58 years [(46.9±8.7)years]. Acute injury was found in 1 patient and chronic injuries in 7 patients, including 3 with cervicothoracic kyphotic deformity and 5 with thoracolumbar kyphotic deformity. Five patients were complicated by odontoid fractures, 1 by C 2-C 3 fracture and 2 by atlantoaxial dislocation. According to American Spinal Injury Association (ASIA) scale, 2 patients were with grade C, 3 with grade D, and 3 with grade E. The patients were treated with posterior upper cervical reduction and fixation combined with cervicothoracic PSO or thoracolumbar PSO respectively according to the location of the deformity. The operation time and intraoperative blood loss were recorded. Neck disability index (NDI), visual analogue scale (VAS), C 0-C 2 angle, C 1-C 2 angle, cervical lordosis angle (CL), head tilt angle (HT), chin-brow vertical angle (CBVA), cervical sagittal vertical axis (CSVA), and sagittal vertical axis (SVA) were compared before surgery, at 1 week and 3, 6, 12 months after surgery, and at the last follow-up. The healing of fractures and fusion of osteotomy site were recorded at 12 months after surgery. Recovery of neurological function was observed at the last follow-up. Incidence of complications was observed. Results:Patients were all followed up for 12-24 months [(17.0±5.4)months]. The operation time was 5.5-7.2 hours [(6.2±0.6)hours] and the intraoperative blood loss was 480-800 ml [(629.4±124.0)ml]. The NDI scores at 1 week and 3, 6, 12 months after surgery, and at the last follow-up were (14.6±2.6)points, (13.6±2.8)points, (12.8±2.4)points, (12.8±2.7)points, and (12.8±2.6)points respectively, significantly lower than (29.6±8.5)points preoperatively ( P<0.01). There were no significant differences in NDI scores at various time points after surgery ( P>0.05). The VAS scores were 2.0(1.0, 3.0)points, 1.5(1.0, 2.0)points, 0.5(0.0, 1.8)points, 0.5(0.0, 1.7)points, and 0.5(0.0, 1.8)points respectively, significantly lower than 3.5(3.0, 4.8)points preoperatively ( P<0.01). The VAS score at 3 months postoperatively was lower than that at 1 week postoperatively ( P<0.05), and the VAS score at 6 months postoperatively was lower than that at 3 months postoperatively ( P<0.05). There were no statistically significant differences in VAS scores at 6, 12 months postoperatively, and at the last follow-up ( P>0.05). There were no statistically significant differences between C 0-C 2 angle and C 1-C 2 angle preoperatively and at different time points postoperatively ( P>0.05). At 1 week and 3, 6, 12 months postoperatively and at the last follow-up, the CL values were -8.5(-5.3, -11.9)°, -8.6(-5.5, -11.9)°, -8.4(5.2, -12.1)°, -8.8(-5.6, -12.4)°, and -8.7(-5.3, -12.5)° respectively, significantly higher than 1.2(9.5, -4.8)° preoperatively ( P<0.01); the HT values were 6.1(4.5, 9.6)°, 6.1(4.3, 9.4)°, 6.0(4.2, 8.9)°, 6.0(4.2, 9.2)°, and 6.1(4.3, 9.2)° respectively, significantly lower than 17.0(10.3, 22.0)° preoperatively ( P<0.01); the CBVA values were (23.2±5.0)°, (23.1±4.8)°, (23.0±4.7)°, (23.1±4.7)°, and (23.1±4.9)° respectively, significantly lower than (44.1±9.8)° preoperatively ( P<0.01); the CSVA values were 5.2(4.2, 7.5)cm, 5.4(4.1, 7.1)cm, 4.7(4.0, 7.4)cm, 5.4(4.1, 7.0)cm, and 5.1(4.3, 6.5)cm respectively, significantly shorter than 9.0(7.8, 9.3)cm preoperatively ( P<0.01); the SVA values were 7.7(6.2, 13.7)cm, 7.5(6.0, 13.4)cm, 7.6(6.2, 13.2)cm, 7.4(6.3, 13.1)cm, and 7.5(6.2, 13.2)cm respectively, significantly shorter than 16.8(8.2, 27.2)cm preoperatively ( P<0.05). There were no statistically significant differences among CL, HT, CBVA, CSVA, and SVA values at different time points after surgery ( P>0.05). All the fractures healed at 12 months after surgery and Bridwell grade I healing was achieved at all the osteotomy sites. At the last follow-up, all the patients were classified as ASIA grade E, significantly improved compared with preoperatively ( P<0.01). One patient had transient C 8 nerve paralysis after surgery and recovered after 4 weeks′ treatment. The remaining patients did not develop any infection or internal fixation-related complications, such as broken rods, broken screws, or loose screws. Conclusion:For AS kyphosis deformity complicated with upper cervical injury, posterior reduction and fixation combined with cervicothoracic or thoracolumbar PSO can effectively promote functional recovery, relieve pain, maintain overall trunk balance, improve neurological symptoms, and reduce the incidence of complications.

Objective:To evaluate the safety and effectiveness of single posterior osteotomy in the correction of rigid cervical spine deformities (CSD) and to explore the indications and key surgical techniques involved.Methods:A retrospective analysis was conducted on the clinical data of 9 patients with rigid CSD who underwent single posterior osteotomy correction between June 2012 and June 2023 in the Department of Spine Surgery at the First Affiliated Hospital of Xinjiang Medical University. The cohort comprised 4 males and 5 females, with a mean age of 19.8±27.2 years (range, 7-48 years). Among these, 5 cases were congenital CSD, 3 were post-tuberculosis deformities, and 1 was iatrogenic. Various coronal and sagittal alignment parameters were measured, including C 1, 2 angle, cervical lordosis (CL), structural scoliosis angle (SSA), structural kyphosis angle (SKA), head tilt (HT), C 2-C 7 sagittal vertical axis (CSVA), sagittal vertical axis (SVA), coronal balance distance (CBD), T 1 slope (T 1S), and the difference between T 1 tilt and cervical lordosis (T 1S-CL). Clinical outcomes were assessed using the neck disability index (NDI), visual analogue scale (VAS), and Scoliosis Research Society-22 questionnaire (SRS-22). Results:The average operation time was 273.9±76.1 min, with an average blood loss of 472.2±128.8 ml. All 9 patients were followed up for an average of 45.2±41.8 months (range, 12-116 months). A total of 7 patients underwent single-segment osteotomies (C 3, C 6 and C 7: 1 case each; C 5: 4 cases), and 2 patients underwent double-segment osteotomies (C 2 and C 7, C 3 and C 4). Four cases involved pedicle subtraction osteotomy (PSO), while 7 cases required vertebral column resection. The upper instrumented vertebra (UIV) was located at the occiput in 1 case and in the cervical spine in 8 cases. The lower instrumented vertebra (LIV) was located in the upper thoracic spine in 6 cases and in the cervical spine in 3 cases, with 2 of the latter cases having both UIV and LIV in the cervical spine. The average number of fused segments was 7.6±4.4 segments (range, 2-12 segments). All patients achieved successful bone fusion within an average of 8.8±3.2 months (range, 6-12 months). Preoperatively, the mean values for CL, SSA, SKA, HT, and CBD were 19.8° (17.2°, 30.5°), 27.4°(23.3°, 30.4°), 28.4°(25.6°, 30.1°), 9.0°(6.2°, 12.3°), and 18.5(12.3, 23.6) mm, respectively. Postoperative improvements were noted with values of -11.1°(-8.8°, -14.4°), 1.3°(0.8°, 1.6°), -11.1°(-8.6°, -14.5°), 1.6°(0.5°, 2.2°), and 9.4 (4.8-13.5) mm, respectively. At the final follow-up, these parameters were maintained, with values of -11.0°(-8.8°, -14.3°), 1.2°(0.8°, 1.5°), -11.0° (-8.6°, -14.3°), 1.5°(0.5°, 2.2°), and 9.4(4.8, 13.4) mm, respectively. Statistically significant improvements were observed between preoperative and postoperative measurements ( P<0.05), except for C 1, 2 angle, CSVA, SVA, T 1S, and T 1S-CL ( P>0.05). NDI and SRS-22 scores showed significant improvements postoperatively ( P<0.05), while VAS scores did not show a significant change ( P>0.05). Postoperative complications included transient nerve injury in two patients, one case of right central retinal artery occlusion, and one case of vertebral artery injury. Conclusion:This study confirms the safety and efficacy of single posterior osteotomy for treating rigid CSD of various etiologies. Standard PSO or modified techniques are effective for correcting cervical kyphosis, while hemivertebra resection and concave-side distraction are recommended for congenital scoliosis or kyphoscoliosis.

Objective:To evaluate the relationship between prognostic nutritional index (PNI) and myocardial injury after non-cardiac surgery (MINS).Methods:This was a retrospective cohort study. The clinical data of adult patients ( n=2 203) who underwent liver resection surgery with general anesthesia at our center from January 2016 to August 2019 were retrospectively collected. The predictive value of preoperative PNI for MINS and the optimal cut-off value of PNI were evaluated and determined according to the receiver operating characteristic curve, and the patients were divided into 2 groups based on the cut-off value: high PNI group and low PNI group. Logistic regression analyses were applied to investigate the relationship between preoperative PNI and MINS. According to the same inclusion and exclusion criteria, the clinical data of patients at our center from January 2022 to December 2023 were collected as the validation set ( n=2 525), and they were grouped using the same PNI cutoff value. Logistic regression analyses were used to verify the relationship between PNI and MINS. Results:The receiver operating characteristic curve analysis showed that the area under the curve of preoperative PNI for predicting MINS was 0.651 (95% confidence interval [ CI] 0.602-0.699), with an optimal cut-off value of 46.193, and the specificity and sensitivity were 0.729 and 0.519 respectively. The integer 46 was considered as the optimal cutoff value for PNI, and the patients were divided into low PNI group (PNI<46, n=606) and high PNI group (PNI≥46, n=1 597). Both univariate and multivariate logistic regression analyses showed that preoperative low PNI was an independent risk factor for the occurrence of MINS (univariate: OR=2.873, 95% CI 2.063-4.003, P<0.001; multivariate: OR=1.844, 95% CI 1.241-2.600, P=0.003). The results in the validation set were still robust (univariate: OR=2.694, 95% CI 1.890-3.833, P<0.001; multivariate: OR=1.602, 95% CI 1.071-2.385, P=0.021). Conclusions:Preoperative low-level PNI is an independent risk factor for MINS, with a certain predictive value.

This study aims to observe the effect of Panax notoginseng extracts on inflammatory re-sponse in immunosuppressed broilers and to investigate the mechanism through network pharma-cology and molecular docking combined with in vivo animal tests.Based on the TCMSP database and GeneCard and other disease databases,we searched for targets related to Panax notoginseng and broiler inflammation,screened key compounds and targets by applying Cytoscape 3.7.1 and String databases,respectively,and constructed a network relationship diagram of traditional Chi-nese medicine(TCM)-key components-targets,and carried out GO functional enrichment and KEGG pathway enrichment analyses by using the DAVID platform.The GO functional enrichment analysis and KEGG pathway enrichment analysis were carried out by the DAVID platform,visual-ized by the Chiplot online website,and finally,the core clustered proteins were analyzed by Pymol software to obtain the core targets,and molecular docking technology was used to predict the de-gree of matching between the active ingredients and the core targets as well as the animal experi-ments to further explore the pharmacological mechanism of Panax notoginseng extracts.Sixty 1-day-old red-feathered broilers were randomly divided into three groups(LPS group,CON group,and PN group),and the test period was 35 days.The LPS and PN groups were injected intraperito-neally with 250 μg/kg body weight of LPS,and the CON group was injected with an equal amount of sterile physiological saline on the 12,14,33,and 35 d.The LPS and PN groups were injected with 250 μg/kg body weight of LPS,and the CON group was injected with an equal amount of sterile physiological saline.The effect of Panax notoginseng extract on inflammatory cytokines in serum was detected by ELISA,and the hormone content in serum was also detected in each group,and fluorescence quantitative PCR was used to detect the effect of each group on the mRNA ex-pression levels of STAT3,IL-6,and CASP3.The results showed that the serum levels of IFN-γ,IL-6,iNOS,TNF-α,and TNF-β were significantly increased(P＜0.05),while the level of IL-10 was significantly decreased(P＜0.05)after LPS tapping at weeks 2 and 5.The serum levels of IFN-y,IL-6,iNOS,TNF-α,and TNF-β were significantly decreased(P＜0.05)and IL-10 was sig-nificantly increased(P＜0.05)by the addition of Panax ginseng extracts to the basal diet com-pared with the LPS group.Panax notoginseng extracts significantly decreased the serum levels of adrenocorticotropic hormone(ACTH)and corticosterone(CORT)(P＜0.05)and increased the levels of growth hormone(GH)(P＜0.05).A total of 8 active ingredients and 123 potential tar-gets for broiler inflammation were predicted by network pharmacology.The protective mechanism of Panax notoginseng against broiler inflammation may be related to the C-type lectin receptor(CLR)signaling pathway,Toll-like receptor(TLR)signaling pathway,MAPK signaling pathway,NOD-like receptor(NLR)signaling pathway,and FoxO signaling pathway.According to the pre-diction,the alleviation of inflammatory response in broiler chickens by Panax notoginseng may be related to the action on 12 key targets.Fluorescence quantitative PCR showed that Panax notogin-seng extract down-regulated the mRNA expression of IL-6 and CASP3(P＜0.05)and up-regula-ted that of STAT3(P＜0.05),and molecular docking results also showed that the active ingredi-ents in Panax notoginseng extracts could exert anti-inflammatory effects through IL-6 and CASP3.The results suggested that Panax quinquefolium extracts might alleviate the inflammatory response of immune-stressed broilers through multi-components,multi-targets,and multi-path-ways,and this study helps propose new therapeutic strategies and provides a theoretical basis for the development of feed additives based on Penthorum chinense Pursh extract.

OBJECTIVE: To explore the regulatory effects of GABAergic neurons in the zona incerta (ZI) on sevoflurane and propofol anesthesia. METHODS: Forty-eight male C57BL/6J mice divided into 8 groups (n=6) were used in this study. In the study of sevoflurane anesthesia, chemogenetic experiment was performed in 2 groups of mice with injection of either adeno-associated virus carrying hM3Dq (hM3Dq group) or a virus carrying only mCherry (mCherry group). The optogenetic experiment was performed in another two groups of mice injected with an adeno-associated virus carrying ChR2 (ChR2 group) or GFP only (GFP group). The same experiments were also performed in mice for studying propofol anesthesia. Chemogenetics or optogenetics were used to induce the activation of GABAergic neurons in the ZI, and their regulatory effects on anesthesia induction and arousal with sevoflurane and propofol were observed; EEG monitoring was used to observe the changes in sevoflurane anesthesia maintenance after activation of the GABAergic neurons. RESULTS: In sevoflurane anesthesia, the induction time of anesthesia was significantly shorter in hM3Dq group than in mCherry group (P < 0.05), and also shorter in ChR2 group than in GFP group (P < 0.01), but no significant difference was found in the awakening time between the two groups in either chemogenetic or optogenetic tests. Similar results were observed in chemogenetic and optogenetic experiments with propofol (P < 0.05 or 0.01). Photogenetic activation of the GABAergic neurons in the ZI did not cause significant changes in EEG spectrum during sevoflurane anesthesia maintenance. CONCLUSION Activation of the GABAergic neurons in the ZI promotes anesthesia induction of sevoflurane and propofol but does not affect anesthesia maintenance or awakening.
