OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets， followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established ， and the zebrafish were treated with L. ruthenicum Murr. extract （LRME） at concentrations of 0.1， 0.2 and 0.4 mg/mL， respectively； 24 h later， behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 （IL-6）， IL-1β， IL-10， tumor necrosis factor-α （TNF-α）]， oxidative stress markers [superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， catalase （CAT）]， and neurotransmitters [5- hydroxytryptamine （5-HT）， γ-aminobutyric acid （GABA）， glutamic acid （Glu）， dopamine （DA）， and norepinephrine （NE）] were measured. The protein expression levels of protein kinase B1 （AKT1）， phosphorylated AKT1 （p-AKT1）， epidermal growth factor receptor （EGFR）， B-cell lymphoma 2 （Bcl-2）， sarcoma proto-oncogene，non-receptor tyrosine kinase （SRC）， and heat shock protein 90α family class A member 1 （HSP90AA1） in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these， apigenin， naringenin and others were recognized as core active compounds， while AKT1， EGFR and others served as key targets； EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-， medium-， and high-dose groups were 54.60%， 69.03% and 77.97%， 开发。E-mail：hjp_yft@163.com respectively， while the inhibition ratios of locomotor distance were 0.57， 0.83 and 0.95， respectively. Compared with the model group， the number of resting counts， resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups （P＜0.05）. Neuronal damage in the brain was alleviated. Additionally， the levels of IL-6， IL-1β， TNF-α， MDA， Glu， DA and NE， as well as the protein expression levels of AKT1， p-AKT1， EGFR， SRC and HSP90AA1， were markedly reduced （P＜0.05）， while the levels of IL-10， SOD， GSH-Px， CAT， 5-HT and GABA， as well as Bcl-2 protein expression， were significantly elevated （P＜0.05）. CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects， and its specific mechanism may be related to the regulation of inflammatory responses， oxidative stress， neurotransmitter balance， and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

In 2022, WHO updated the classification and concept of adrenal cortical and medullary tumors. In terms of adrenal cortical tumors, the WHO classification further standardizes the nomenclature of nodular adrenal cortical disease and refines the pathological classification of primary aldosteronism. In terms of adrenal medullary tumors, the WHO classification unifies the concepts of pheochromocytoma and paraganglioma, and reclassifies various concepts, including paraganglioma-like neuroendocrine tumors. The new standards not only cover the clinical manifestations of the disease, but also include other multiple aspects such as the histological origin of the disease, immunohistochemical manifestations, physiological mechanisms of the disease, hereditary susceptibility and prognostic factors. This article intends to explore how to improve the diagnostic and therapeutic level of adrenal tumors.

Objective:To explore the influence factors for futile recanalization following endovascular treatment(EVT)in patients with acute basilar artery occlusion(BAO).Methods:Clinical data of patients with acute BAO,who underwent endovascular treatment within 24 h of onset from January 2017 to November 2022,were retrospectively analyzed.The futile recanalization was defined as modified thrombolysis in cerebral infarction(mTICI)grade≥2b or 3 after successful reperfusion,but the modified Rankin Scale score>2 at 3 months after EVT.Binary logistic regression model was used to analyze the influencing factors of futile recanalization.Results:A total of 471 patients with a median age of 68(57,74)years were included and 68.9%were males,among whom 298(63.27%)experienced futile recanalization.Multivariate analysis revealed that concomitant atrial fibrillation(OR=0.456,95%CI:0.282-0.737,P<0.01),bridging thrombolysis(OR= 0.640,95%CI:0.416-0.985,P<0.05),achieving mTICI grade 3(OR=0.554,95%CI:0.334-0.918,P<0.05),arterial occlusive lesion(AOL)grade 3(OR=0.521,95%CI:0.326-0.834,P<0.01),and early postoperative statin therapy(OR=0.509,95%CI:0.273-0.948,P<0.05)were protective factors for futile recanalization after EVT in acute BAO patients.High baseline National Institutes of Health Stroke Scale(NIHSS)score(OR=1.068,95%CI:1.049-1.087,P<0.01),coexisting hypertension(OR=1.571,95%CI:1.017-2.427,P<0.05),multiple retrieval attempts(OR=1.237,95%CI:1.029-1.488,P<0.05)and postoperative hemorrhagic transformation(OR=8.497,95%CI:2.879-25.076,P<0.01)were risk factors.For trial of ORG 10172 in acute stroke treatment(TOAST)classification,cardiogenic embolism(OR=0.321,95%CI:0.193-0.534,P<0.01)and other types(OR=0.499,95%CI:0.260-0.961,P<0.05)were related to lower incidence of futile recanalization.Conclusions:The incidence of futile recanalization after EVT in patients with acute BAO is high.Bridging venous thrombolysis before operation and an early postoperative statin therapy may reduce the incidence of futile recanalization.

The survival rate of fat grafts is challenging to predict, and related complications such as oil cyst formation and fat necrosis may occur. The primary cause is that adipocytes are destroyed during fat grafting, and adipocyte necrosis releases a large number of oil droplets. Understanding the lipid metabolism of fat grafts, including intracellular lipid metabolism and extracellular oil droplet metabolism, is crucial to improve the survival rate of fat grafts and reduce complications. This article primarily explored the lipid metabolism and associated immune regulation of adipocytes and macrophages under both physiological and inflammatory conditions after fat grafting, and explained the mutual regulatory relationship between fat graft metabolism and the host’s overall lipid metabolism.

Objective:To investigate the clinical application value of the new tracer mitoxantrone hydrochloride in imaging of cervical lymph nodes and identifying of parathyroid, recurrent laryngeal nerve during thyroid cancer radical surgery.Methods:A prospective controlled study was conducted between January 2022 and April 2024 at Tianjin First Central Hospital, recruiting 180 patients with thyroid cancer, including 54 males and 126 females, aged from 26 to 69 years. The patients were randomly divided into three groups: the mitoxantrone hydrochloride lymph node tracing group (MHI group), the nanocarbon lymph node tracing group (nanocarbon group), and the control group without lymph node tracers, with 60 cases in each group. All patients underwent total thyroid resection and regional lymph node dissection. The number of detected lymph nodes and positive metastatic lymph nodes and surgical field clarity scores and the identification rate of parathyroid glands and the instances of inadvertent excision were compared between the groups. Serum calcium and parathyroid hormone (PTH) levels at different perioperative time points and treatment-related complications were analyzed. One-way ANOVA, chi-square test and two independent sample non-parametric tests, were employed for statistical analyses.Results:The mean operation time, neck drainage volume and hospital stay in the MHI group and the nanocarbon group were respectively significantly lower than those in the control group ( P<0.05). The mean staining intensity score, tracer success rate and surgical field clarity score in MHI group were respectively significantly higher than those in nanocarbon group ( P<0.05). The mean numbers of dissected lymph nodes positive metastatic nodes and identification rates of parathyroid glands in MHI group were respectively significantly higher than those in both the nanocarbon and control groups ( P<0.05). The rates of inadvertent parathyroid excision in both MHI group and nanocarbon group were significantly lower than those in control group ( P<0.05). On postoperative day 1 and day 5, mean serum calcium and PTH levels in MHI group were respectively significantly higher than those in nanocarbon group and control groups. However, on postoperative day 1, there was no difference in mean serum calcium levels between the nanocarbon group and the control group ( P>0.05), though PTH level in the nanocarbon group was higher than that in the control group. By postoperative day 5, both serum calcium and PTH levels were higher in the nanocarbon group compared to the control group ( P<0.05). On postoperative days 30, there were no differences in serum calcium and PTH levels between the MHI group and the nanocarbon group ( P>0.05). The risks of facial numbness, hand and foot tetany and choking during drinking were lower in both the MHI and nanocarbon groups compared to the control group ( P<0.05). Conclusion:MHI demonstrates advantages in rapid targeted delivery and clear staining of the surgical field during regional lymph node dissection in radical thyroidectomy for thyroid cancer, effectively reducing the risk of collateral damage to the recurrent laryngeal nerve and parathyroid glands.

Polycystic ovary syndrome （PCOS） is a common endocrine disorder among women of childbearing age. Persistent chronic inflammation can promote the progression of PCOS， thereby causing serious impacts on women’s endocrine metabolism， reproductive function， and psychological status. Nuclear factors- κB （NF- κB） signaling pathway is one of the most classic inflammatory response transduction pathways and is closely related to the pathological process of PCOS. This article summarizes the mechanism of traditional Chinese medicine intervention in PCOS based on the NF-κB signaling pathway， and finds that various monomers of traditional Chinese medicine [flavonoids （naringenin， soy isoflavone， rhamnocitrin， etc.）， alkaloids （berberine， ligustrazine） and terpenoids （artesunate， cryptotanshinone）， glycosides （salidroside， glycyrrhizic acid）] and traditional Chinese medicine compounds [formula for tonifying kidney （Bushen huayu formula， Bushen huatan formula， etc.）， formula for eliminating damp and dissolving phlegm （Cangfu daotan decoction， Xiehe yin， Erchen decoction）， formula for regulating blood circulation and removing stasis （Gexia zhuyu decoction， Huatan tongmai yin）] can alleviate inflammatory response， improve abnormal glucose and lipid metabolism， and enhance ovarian function by inhibiting NF-κB signaling pathway， thus improving PCOS.

Objective To investigate the effect of dynamic monitoring of occlusal force on the final therapeutic effect and the change of periodontal supporting tissue during combined periodontal orthodontic treatment.Methods The periodontal clinical index of 20 patients with traditional periodontal orthodontic treatment and 20 patients with combined periodontal orthodontic treatment assisted by T-Scan Ⅲ and Anycheck digital occlusion analysis system were compared before,during and after treatment,as well as the changes of bite force,bite time and tooth mobility in the experimental group.Results The depth of periodontal pocket(PD),loss of attachment(AL),bleeding index(BI)and tooth looseness were significantly reduced after combined periodontal orthodontic treatment in both groups.In the control group,the percentage of anterior and posterior biting force changed obviously,and the occlusion force balance was improved.Conclusion The combined treatment of periodontitis and orthodontics can improve the periodontal tissue of patients with periodontitis,and T-Scan system can observe and guide the adjustment of occlusal and better achieve occlusion force balance.

Objective To evaluate the potency of applying an artificial intelligence(AI)based model for classifying vertebral fractures in lumbar X-ray images.Methods Patients who underwent lateral lumbar X-ray and MRI were retrospectively selected.Based on MRI results,the vertebrae were categorized as fresh fractures,old fractures,and normal vertebrae.A ResNet-18 classification model was constructed using delineated region of interest(ROI)on the X-ray images,and the model's performance was evaluated.Results A total of 272 patients(662 vertebrae)were included in this study.The vertebrae were randomly divided into training(n=529)and validation(n=133)sets.The model's performance in discerning normal vertebrae,fresh fractures,and old fractures revealed accuracy of 0.91,0.42,and 0.75,and the sensitivity were 0.91,0.408,and 0.72,while the specificity were 0.796,0.892,and 0.796,respectively.Conclusion The X-ray-based ResNet-18 AI model has significant accuracy for distinguishing old fractures and normal vertebrae;However,the model's accuracy needs further improvement for distinguishing fresh fractures.
