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.

TCM proposes that the core pathological mechanism of depression is"deficient qi with stagnation and heat",with the following pathogenic characteristics and evolution patterns:"deficient qi"as the nature,and deficiency in nature is in spleen,and deficiency in superficiality is in brain;"stagnation"is the superficiality,and qi stagnation,phlegm stagnation,and blood stagnation are in the brain collaterals;"heat"fires the brain collaterals,depression raised the heat,and excessive heat accumulated to stagnation.Based on the understanding of the pathogenesis of depression caused by stress sensitization in modern medicine,this article explored the potential association between this mechanism and the core pathogenesis of"deficient qi with stagnation and heat".It proposed that tonifying deficiency,promoting circulation,and clearing heat are the basic treatment principles for depression.By inhibiting inflammatory reactions and improving the stress sensitization state of neurons and glial cells,TCM compound formulas can exert multi-target and multi-dimensional therapeutic characteristics.

Objective To explore the impacts of compensatory function of the anterior communicating artery(ACoA)on the measurement of blood flow velocity and the degree of stenosis of the non-operative carotid artery in patients with bilateral carotid atherosclerotic stenosis.Methods A total of 161 patients with carotid artery stenosis and the ACoA patency,who underwent unilateral carotid endarterectomy(CEA)from January 2019 to January 2021,were enrolled into this study.Examination was performed using transcranial color-coded Doppler(TCCD)and(or)transcranial Doppler ultrasound(TCD)and confirmed by DSA and(or)CT angiography(CTA).According to whether the ACoA compensation was complete,all patients were divided into complete ACoA group(69 cases)and incomplete ACoA group(92 cases).The peak systolic velocity(PSV)and end-diastolic velocity(EDV)measured by the carotid ultrasound were compared between the complete ACoA group and the incomplete ACoA group before and after CEA.In addition,the results of stenosis degree of non-operative carotid artery evaluated by the ultrasound and DSA or CTA were analysed for the consistency.Results There was no significant difference in age,gender and risk factors for cerebrovascular disease between the two groups(all P＞0.05).Within 1 week after CEA,the PSV([107±35]cm/s,[122±40]cm/s)and EDV([37±12]cm/s,[47±16]cm/s)of the nonoperative carotid artery decreased significantly when compared with those before CEA in both complete and incomplete ACoA patent groups(PSV[177±58]cm/s,[163±54]cm/s and EDV[64±21]cm/s,[76±25]cm/s,all P＜0.01).In the complete ACoA group,the stenosis degrees of non-operative carotid arteries assessed by the CDU were inconsistent with that assessed by the DSA or CTA(Kappa=0.074).Of the 58 patients with mild stenosis assessed by DSA or CTA,55(94.8％)were overestimated as moderate stenosis,and 2(3.4％)were overestimated as severe stenosis.Of the 9 patients with moderate stenosis assessed by DSA or CTA,8 had ultrasound overestimation to severe stenosis.In the incomplete ACoA group,it was highly consistent with that assessed by the DSA or CTA(Kappa=0.920).Of 70 patients with mild stenosis assessed by DSA or CTA,2 cases(2.9％)were overestimated as moderate stenosis by ultrasound.Of the 9 patients with moderate stenosis assessed by DSA or CTA,1 was overestimated by ultrasound to be severe stenosis.Conclusion Non-operative carotid artery PSV and EDV were significantly higher in patients with bilateral carotid artery stenosis with patency and complete compensatory function of ACoA,leading to overestimation the degree of carotid artery stenosis.

Objective:Evaluate the effects of brief mindfulness meditation training on improving negative e-motions,mindfulness attention awareness,and sleep quality in patients after percutaneous coronary intervention(PCI)for coronary heart disease.Methods:Eighty-four patients with coronary heart disease after PCI admitted to the cardiology department were selected.According to the principle of simple randomization,they were divided into an intervention group of 42 cases and a control group of 42 cases.The Self Rating Anxiety Scale/Self Rating De-pression Scale,Mindfulness Attention Awareness Scale,and Pittsburgh Sleep Quality Index Scale were used as eval-uation indicators before and after intervention.Results:The difference in total scores of anxiety,depression,and mindfulness attention awareness before and after intervention in the intervention group was higher than that in the control group(P＜0.05).The difference in total sleep score,sleep quality,time to fall asleep,sleep duration,use of hypnotic drugs,daytime dysfunction,and total sleep score before and after intervention was higher than that of the control group(P＜0.05).Conclusion:It suggests that brief mindfulness meditation training could alleviate negative emotions in patients with coronary heart disease after PCI,improve mindfulness awareness,and improve sleep quali-ty.

Objective To investigate the relationship between intracranial arterial calcification and prognosis after mechanical thrombectomy in patients with acute large vessel occlusion stroke. Methods A total of 147 patients with acute large vessel occlusion stroke who underwent mechanical thrombectomy were enrolled in this study. The length, density, and location of intracranial arterial calcification were evaluated by CT. Based on the intracranial arterial calcification status, patients were divided into three groups: symptomatic intracranial arterial calcification group (n=42), asymptomatic intracranial arterial calcification group (n=24), and no intracranial arterial calcification group (n=81). Multivariate Logistic regression analysis was performed to explore the relationship between intracranial arterial calcification and clinical outcomes after mechanical thrombectomy. Results Compared with patients in the asymptomatic and no intracranial arterial calcification groups, patients in the symptomatic intracranial arterial calcification group, had older age, a higher proportion of hypertension, and required more rescue angioplasty or stenting after mechanical thrombectomy (P < 0.05). There was a statistically significant difference in the location of calcification between the symptomatic and asymptomatic intracranial arterial calcification groups (P < 0.05), but no significant differences in the length and density of calcification between the two groups were observed (P>0.05). Multivariate Logistic regression analysis revealed that symptomatic intracranial arterial calcification was an independent risk factor for failed revascularization (adjusted OR=8.67, 95%CI, 2.39 to 15.68, P < 0.001), the need for rescue interventional therapy (adjusted OR=6.46, 95%CI, 2.26 to 14.29, P < 0.001), and poor neurological recovery (adjusted OR=3.91, 95%CI, 1.38 to 10.16, P=0.023) after adjusting for potential confounding factors. Conclusion Symptomatic intracranial arterial calcification is closely associated with poor clinical outcomes after mechanical thrombectomy in patients with acute large vessel occlusion stroke. Preoperative assessment of intracranial arterial calcification is crucial for selecting revascularization strategies in these patients.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Ferroptosis is a form of regulated cell death, characterized by excessive membrane lipid peroxidation in an iron- and ROS-dependent manner. Celastrol, a natural bioactive triterpenoid extracted from Tripterygium wilfordii, shows effective anti-fibrotic and anti-inflammatory activities in multiple hepatic diseases. However, the exact molecular mechanisms of action and the direct protein targets of celastrol in the treatment of liver fibrosis remain largely elusive. Here, we discover that celastrol exerts anti-fibrotic effects via promoting the production of reactive oxygen species (ROS) and inducing ferroptosis in activated hepatic stellate cells (HSCs). By using activity-based protein profiling (ABPP) in combination with bio-orthogonal click chemistry reaction and cellular thermal shift assay (CETSA), we show that celastrol directly binds to peroxiredoxins (PRDXs), including PRDX1, PRDX2, PRDX4 and PRDX6, through the active cysteine sites, and inhibits their anti-oxidant activities. Celastrol also targets to heme oxygenase 1 (HO-1) and upregulates its expression in activated-HSCs. Knockdown of PRDX1, PRDX2, PRDX4, PRDX6 or HO-1 in HSCs, to varying extent, elevated cellular ROS levels and induced ferroptosis. Taken together, our findings reveal the direct protein targets and molecular mechanisms via which celastrol ameliorates hepatic fibrosis, thus supporting the further development of celastrol as a promising therapeutic agent for liver fibrosis.

Objective:To examine the correlation factors of contralateral central lymph node metastasis in unilateral papillary thyroid carcinoma with lateral cervical lymph node metastasis.Methods:The clinical data of patients with unilateral papillary thyroid carcinoma who underwent total thyroidectomy and bilateral central lymph node dissection and ipsilateral cervical lymph node dissection from June 2016 to June 2018 at Department of Thyroid Surgery, West China Hospital, Sichuan University were analyzed retrospectively. A total of 317 patients, including 87 males and 230 females, aged (41.4±12.1) years (range: 16 to 75 years), were enrolled in this study. The risk factors of contralateral central lymph node metastasis were analyzed by χ 2 test and Spearman correlation analysis. Results:There were 116, 69, 269, and 181 cases of pretracheal lymph node, prelaryngeal lymph node, ipsilateral central lymph node and contralateral central lymph node metastasis, respectively, and 16 cases of skipping metastasis. Univariate analysis showed that contralateral central lymph node metastasis was associated with gender, maximum tumor diameter, capsule invasion, pretracheal lymph node metastasis, prelaryngeal lymph node metastasis, and ipsilateral central lymph node metastasis (all P<0.05). Spearman correlation analysis showed that male ( r s=0.162, P=0.004), maximum tumor diameter>10 mm ( r s=0.184, P=0.001), capsule invasion ( r s=0.135, P=0.016), pretracheal lymph node metastasis ( r s=0.394, P<0.01), prelaryngeal lymph node metastasis ( r s=0.272, P<0.01) and ipsilateral central lymph node metastasis ( r s=0.203, P<0.01) were independent correlation factors for contralateral central lymph node metastasis. Conclusion:For patients with unilateral papillary thyroid carcinoma with ipsilateral cervical lymph node metastasis, bilateral central lymph node dissection should be considered if male, tumor diameter>10 mm, capsule invasion, pretracheal lymph node metastasis, prelaryngeal lymph node metastasis, or ipsilateral central lymph node metastasis.

Objective To explore the impact of hypothyroidism on left ventricular ( LV ) mechanics using two-dimensional speckle tracking imaging ( 2D-STI ) . Methods Forty-two patients with newly diagnosed overt hypothyroidism ( HT ) were prospectively collected as the case group and 47 subjects matching by age ,gender and hypertension history were enrolled as control group . All participants received comprehensive echocardiography examination ,and 2D-STI was used to assess LV global longitudinal strain ( GLS) and mechanical dispersion ( MD ) . The inter-group difference in GLS and MD ,correlations with thyroid hormones and reproducibility were evaluated . Results LV GLS at both sectional ( apical 4- ,3- ,2-chamber views) and global levels were significantly impaired in the HT group than the control group [ ( - 21 .3 ± 3 .2) ％ vs ( - 23 .9 ± 2 .9) ％ ,( - 20 .4 ± 3 .8 ) ％ vs ( - 22 .7 ± 2 .9 ) ％ ,( - 21 .2 ± 3 .9) ％ vs ( - 23 .9 ± 2 .5) ％ ,( - 20 .9 ± 3 .4) ％ vs ( - 23 .5 ± 2 .3) ％ ;all P < 0 .01] . Similarly ,MD at both sectional ( apical 4- ,3- ,2-chamber views) and global levels were significantly prolonged in the HT group than the control group[ 3 .4 ms vs 0 .9 ms ,2 .2 ms vs 0 .7 ms ,2 .3 ms vs 1 .7 ms and 12 .2 ms vs ( 5 .9 ± 2 .6) ms ;all P < 0 .01] . No significant correlation was found between MD and GLS ,left ventricular ejection fraction ( LVEF) ( r = 0 .12 , P = 0 .27 ; r = - 0 .17 , P = 0 .10) . Weak correlations were found between MD and FT3 ,FT4 ,TSH( r = - 0 .34 , P = 0 .01 ; r = - 0 .38 , P = 0 .005 ; r = 0 .31 , P = 0 .02) . Conclusions Primary overt HT is associated with impaired LV deformation and increased systolic dyssynchrony . LV MD is a promising parameter for assessment of myocardial impairment in HT .
