OBJECTIVE To investigate the effects and mechanisms of oliceridine fumarate （TRV130） in improving postoperative cognitive dysfunction （POCD） in elderly rats based on the Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB） pathway. METHODS Rats were randomly divided into the control group （normal saline）， the model group （normal saline）， the TRV130 group （2.8 mg/kg）， the TLR4/NF-κB pathway inhibitor （TAK-242） group （3 mg/kg）， the β -arrestin inhibitor （Barbadin） group （3 mg/kg）， and the traditional opioid drug （morphine） group （2.8 mg/kg）， with 15 rats in each group. Except for the control group， POCD models were established in all other groups. From the first day after surgery， drugs/normal saline were administered via caudal vein injection once daily for 3 consecutive days. After the last administration， the pathological damage of hippocampal tissue was observed； the cognitive function， serum inflammatory factor levels， hippocampal neurons apoptosis rate， and the expression of ionized calcium-binding adapter molecule 1 （Iba-1）， glial fibrillary acidic protein （GFAP）， and TLR4/NF-κB pathway-related mRNA and protein in hippocampal tissue were detected. RESULTS In the model group， the neurons in the CA1 region of the hippocampus were disordered and sparse， with decreased number， pyknotic and fragmented nuclei accompanied by inflammatory cell infiltration. Compared with the control group， the escape latency， serum levels of tumor necrosis factor α （TNF-α）， interleukin-6 （IL-6）， and IL-1β， hippocampal neurons apoptosis rate， average fluorescence intensities of Iba-1 and GFAP， mRNA expression levels of TLR4 and NF-κB p65， and their protein expression/phosphorylation levels in hippocampal tissue were significantly increased/elevated in the model group （ P ＜0.05）； the time spent in the target quadrant and the number of platform crossings were significantly shortened/decreased （ P ＜0.05）. Compared with the model group， the cognitive function， pathological， inflammatory， and apoptosis-related indicators were significantly improved in the TRV130 group， TAK-242 group， and Barbadin group （ P ＜0.05）； the mRNA expression levels of TLR4 and NF-κB p65 and their protein expression/phosphorylation levels were significantly decreased in the TRV130 group and TAK-242 group （ P ＜0.05）. CONCLUSIONS TRV130 may improve POCD in elderly rats by inhibiting the TLR4/NF-κB pathway and alleviating postoperative central nervous system inflammatory responses.

Oral lichen planus (OLP) is a common chronic inflammatory disease and potentially malignant disorder of the oral mucosa. Clinical manifestations include bilateral symmetrical distributions of pearly white reticular streaks, and its subtype erosive oral lichen planus (EOLP) is often accompanied by local congestion, erosion, obvious pain, and other symptoms, which affects the patient's eating and swallowing. Oral hygiene and environmental factors, lifestyle and dietary factors, psychological factors, medication factors, and systemic disease factors all contribute to the recurrence of EOLP lesions, which increases the cancer potential of this condition. Therefore, measures to prevent the recurrence and cancerous transformation of EOLP have attracted much attention. In the clinical treatment strategy for EOLP, attention should be given to its influencing factors for comprehensive management. Patients should be provided with multidisciplinary and multifaceted oral comprehensive management measures across the following strategies: maintaining a good oral hygienic environment, dietary therapies and healthy living habits, psychological therapies, systemic/local therapeutic guidance, and active follow-up and treatment of systemic diseases. This article provides multidisciplinary and multifaceted comprehensive oral management measures for patients with the goal of cancer prevention, minimizing recurrence, and improving the quality of life of patients.

Objective To investigate expression changes and regulatory roles of adhesion G protein-coupled receptor F1 (ADGRF1/GPR110) in metabolic dysfunction-associated steatohepatitis (MASH)-related hepatic fibrosis. Methods Human MASH liver tissues were collected for GPR110 detection via real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and immunohistochemistry. Eight-week-old male C57BL/6 mice were randomly divided into four groups: control＋AAV-GFP group, control＋AAV-GPR110 group, MASH＋AAV-GFP group, and MASH＋AAV-GPR110 group. MASH was induced by high-fat with high-sucrose diet and low-dose CCl₄ intraperitoneal injections, with AAV-GPR110/AAV-GFP delivered via tail vein. Liver tissues were harvested at designated intervals (4 w, 8 w, and 12 w). Western blotting measured GPR110 expression; hematoxylin-eosin and oil red O staining assessed histology and lipid content; F4/80 and α-smooth muscle actin (α-SMA) immunofluorescence staining evaluated inflammation and fibrosis; qRT-PCR quantified hepatic expression of lipid metabolism, inflammatory, and fibrotic genes. Results GPR110 expression was significantly reduced in livers of MASH patients compared with controls (P＜0.05). MASH＋AAV-GPR110 mice exhibited lower weight, liver index, and serum lipids compared with MASH＋AAV-GFP (P＜0.05). Lipid synthesis-related gene (SCD-1), lipid uptake-related gene (CD36), gluconeogenesis-related genes (PEPCK and G-6-Pase), and inflammation-related genes (TNF-α, NF-κB, and iNOS) in liver were downregulated in MASH＋AAV-GPR110 (P＜0.05). Hepatic F4/80^＋ and α-SMA^＋ areas decreased in MASH＋AAV-GPR110 (P＜0.05). Conclusion GPR110 overexpression ameliorates hepatic lipid accumulation, reduces inflammation, and delays fibrosis in MASH.

ObjectiveTo explore the effects of the Tai Chi training on bone density， bone turnover markers， and heart rate variability for people with high-risk osteoporosis， and to provide evidence for the prevention of osteoporosis at early stage. MethodsSixty-six cases of people with high risk of osteoporosis were included， and they were divided into 33 cases each in the intervention group and the control group using the random number table method. The control group received osteoporosis health education three times a week， and the intervention group received Tai Chi training under the guidance of a trainer three times a week for 40 mins each time on the basis of the control group， and both groups were intervened for 12 weeks. Dual-energy X-ray absorptiometry was used to measure the bone density of L₁~L₄ vertebrae， bilateral femoral necks and bilateral total hips in the two groups before and after the intervention； enzyme-linked immunosorbent assay was used to determine bone turnover markers before and after the intervention， including pro-collagen type Ⅰ pro-amino-terminal prepropyl peptide （P1NP） and β-collagen type Ⅰ cross-linking carboxy-terminal peptide （β-CTX）. Seven cases with good compliance in the intervention group were selected. After wearing the heart rate sensor， they successively performed Tai Chi training and walking activities recommended by the guideline for 20 mins each， and the heart rate variability （HRV） during exercise was collected， including time-domain indexes such as standard deviation of normal sinus intervals （SDNN）， root-mean-square of the difference between adjacent RR intervals （RMSSD）， frequency-domain metrics such as low-frequency power （LF）， high-frequency power （HF）， and low-frequency/high-frequency power ratio （LF/HF）， as well as nonlinear metrics such as approximate entropy （ApEn）， sample entropy （SampEn）. ResultsFinally， 63 cases were included in the outcome analysis， including 30 cases in the intervention group and 33 cases in the control group. After the intervention， the differences of L₁~L₄ vertebrae， bone density of bilateral femoral neck and bilateral total hip in the intervention group were not statistically significant when compared with those before intervention （P＞0.05）， while the bone density of all parts of the control group decreased significantly compared with that before intervention （P＜0.05）， and the difference in the bone density of the L₁~L₄ vertebrae， bilateral femoral neck， and the right total hip before and after the intervention of the intervention group was smaller than that of the control group （P＜0.05）. The differences in P1NP and β-CTX between groups before and after intervention was not statistically significant （P＞0.05）. Compared with walking exercise， LF decreased， HF increased and LF/HF decreased during Tai Chi exercise （P＜0.05）； the time domain indexes and non-linear indexes between groups had no statistically significant difference （P＞0.05）. ConclusionTai Chi exercise can maintain lumbar， hip， and femoral bone density and improve sympathetic/parasympathetic balance in people at high risk for osteoporosis， but cannot significantly improve bone turnover markers.

To implement the Opinions of the State Council of the Central Committee of the Communist Party of China on Promoting the Inheritance and Innovative Development of Traditional Chinese Medicine， delve into the diseases specifically responding to traditional Chinese medicine （TCM）， and serve the building of advantageous specialties， clinical talent cultivation， national research layout， and academic innovation， the Chinese Association of Chinese Medicine sponsored the salons in multiple fields to discuss the diseases specifically responding to TCM. On August 26， 2023， the 25^th salon on the diseases specifically responding to TCM was held in Shanghai. In view of the advantages of TCM and integrated traditional Chinese and Western medicine in the diagnosis and treatment of psoriasis， Chinese and western medicine experts and interdisciplinary researchers carried out extensive and in-depth discussions and formed specific suggestions and consensus on the diagnosis and treatment of psoriasis with TCM and integrated traditional Chinese and Western medicine. However， there was still a lack of detailed research path. Under the guidance of the Chinese Association of Chinese Medicine， this paper analyzes the problems in the diagnosis and treatment of psoriasis from the occurrence and development of psoriasis. According to the advantages and characteristics of TCM and integrated traditional Chinese and Western medicine in the diagnosis and treatment of psoriasis， this paper puts forward the main points of research layout for psoriasis from the three aspects of psoriasis diagnosis and treatment， comorbidity prevention， and chronic disease management as follows： ① optimization of the syndrome differentiation system for psoriasis， ② optimization of assessment indicators for psoriasis， ③ recurrence mechanisms of psoriasis， ④ construction and research of TCM prevention and treatment of psoriasis recurrence， ⑤ construction of the comorbidity spectrum and TCM theoretical system of psoriasis， ⑥ comorbidity mechanisms of psoriasis. Furthermore， this article proposed the research layout and directions， expected goals and values， and funding priorities. Therefore， on the basis of the series of salons about psoriasis as a disease specifically responding to TCM， this article puts forward the research paradigm of psoriasis， aiming to facilitate the high-quality development of TCM and provide reference for the national research layout， the research and development of new TCM preparations， the selection of research topics， and the formulation of guidelines and consensus.

Objective To investigate the effect of obstructive sleep apnea syndrome(OSAS)on nocturnal ambulatory blood pressure monitoring results in older adults without cardiovascular or cerebrovascular diseases,and to identify factors causing fluctuations in nocturnal blood pressure in older adults with OSAS.Methods A total of 169 older adult OSAS patients with no history of cardiovascular or cerebrovascular diseases were enrolled.According to their severity of OSAS,the participants were divided into 4 groups,including a normal OSAS group,a mild OSAS group,a moderate OSAS group,and a severe OSAS group.The baseline characteristics of the 4 groups were compared to identify differences.The relationship between polysomnography parameters and nocturnal ambulatory blood pressure monitoring results and the factors causing nocturnal blood pressure fluctuations in older adults with OSAS were further analyzed.Results The nocturnal blood pressure fluctuation(NBPF)index of the normal OSAS group,the mild OSAS group,the moderate OSAS group,and the severe OSAS group were 1.89±1.58,3.35±5.40,3.90±6.40,and 16.60±27.70,respectively,indicating that the NBPF index gradually increased with the increasing severity of OSAS(P＜0.05).According to findings from the partial correlation analysis,the NBPF index was positively correlated with apnea-hypopnea index(AHI),micro-awakening index(MAI),percentage of cumulative time with oxygen saturation under 90％in the total sleep time(TS90％),oxygen desaturation index(ODI),and the longest apnea time(LAT)(P＜0.05),and negatively correlated with the lowest oxygen saturation(LSpO2)and sleep quality index(SQI)(P＜0.05).The mean nocturnal systolic and diastolic blood pressures were positively correlated with AHI,ODI,and TS90％(P＜0.05).A multi-factor regression analysis showed that every time ODI increased by 1 unit,the NBPF index increased by 0.26 units(β=0.26;95％CI,0.03-0.50;P=0.030),and every time TS90％increased by 1 unit,the NBPF index increased by 26.78 units(β=26.78;95％CI,2.47-51.08;P=0.031).Conclusion In older adult OSAS patients without cardiovascular or cerebrovascular disease,fluctuations in blood pressure at night become more pronounced with increasing disease severity.ODI and TS90％are important factors that affect nocturnal blood pressure fluctuations.

Objective To evaluate the long-term effects of orthokeratology(ortho-k)lenses with different back optical zone diameters(BOZD)on the quality of vision in myopic children.Methods We conducted an exploratory analysis based on a prospective,randomized,double-blind clinical trial,focusing on the parameters related to visual quality.A total of 66 myopic children aged 8 to 12 years were enrolled and randomly assigned to either a 6-mm BOZD ortho-k lens group(the 6 mm group)or a 5-mm BOZD ortho-k lens group(the 5 mm group).The participants were followed up at baseline,and at 1 day,1 week,and 1,3,6,9,and 12 months after lens wearing.Visual quality measurements included uncorrected visual acuity(VA),best corrected VA,contrast sensitivity(CS),high-order aberrations(HOA),modulation transfer function(MTF),Strayer ratio(SR),and visual quality questionnaire.Results A total of 63 children(33 children in the 6 mm group and 30 children in the 5 mm group)completed the study.There were no significant differences in baseline data between the two groups(P>0.05).There were no significant differences in subjective uncorrected VA or best corrected VA between the two groups at any follow-up visit(P>0.05).After wearing the lenses for 3 months,the CS at high spatial frequency(18 cpd)in the 5 mm group was lower than that in the 6 mm group(P=0.015).However,at 12 months,no significant differences in the CS were found between the two groups(P>0.05).The ocular and corneal total HOA,spherical aberration,and coma aberration in both groups increased after wearing the lenses,and the HOA in the 5 mm group was higher than that in the 6 mm group(all P<0.05).After wearing the lenses for 3 months,the MTF and SR values in the 5 mm group were lower than those in the 6 mm group(P<0.05).At 12 months,there was no significant difference between the two groups(P>0.05).The vision-quality-related questionnaire scores showed no significant differences between the two groups(P>0.05).Conclusion In myopic children,wearing ortho-k lenses with different BOZD results in improved subjective satisfaction,with no difference in subjective visual quality.However,objective visual quality declined in both groups,with a greater impact observed in the 5 mm group.

Objective To investigate the role of additional platelet protein kinase C epsilon(PKCε)assay in risk stratification and additional diagnostic testing in elderly patients with acute chest pain and normal hypersensitive cardiac troponin I(hs-cTnI)level.Methods A prospective trial was conducted on 220 consecutive elderly patients with angina-like acute chest pain and normal hs-cTnI level in our hospital from April 2022 to April 2023.According to whether major adverse cardiovascular events(MACE)occurred during the 1-year follow-up period,they were assigned in-to MACE group(24 cases)and non-MACE group(196 cases).Their general clinical data and platelet PKCε expression were compared between the two groups.Kaplan-Meier survival curve was plotted to analyzed the event-free time between the platelet PKCε expression＜2.05％group and the≥2.05％group.Multivariate Cox regression analysis was used to investigate the impact of baseline data on the occurrence of MACE during the 1-year follow-up period.Decision tree model was employed to analyze the influencing factors for MACE.Results During 1-year follow-up,24 patients(10.91％)developed MACE.The platelet PKCε expression was significantly higher in the MACE group than the non-MACE group[9.25％(6.60％,15.25％)vs 1.70％(0.80％,3.25％),Z=-7.596,P＜0.01].Kaplan-Meier survival curve analysis showed that the patients in the PKCε＜2.05％group had no events within 360 d,while those in the ≥2.05％group had an average event-free time of 297.13±12.77 d,with a statistical difference(log rank Chi-square=27.051,P=0.000).Multivariate Cox regression analysis showed that highly suspicious angina,hs-cTnI and platelet PKCε were independent risk factors for MACE within 1 year of follow-up(HR=3.011,95％CI:1.049-8.641,P=0.040;HR=1.216,95％CI:1.044-1.418,P=0.012;HR=1.160,95％CI:1.104-1.218,P=0.000).In the decision tree model,the 1-year incidence of MACE was notably higher in the platelet PKCε≥2.05％group than the＜2.05％group(P=0.011).The probability of severe coronary artery stenosis or myocardial ischemia in the platelet PKCε≥2.05％group was remarkably higher than the＜2.05％group(P=0.006).Conclusion In elderly patients suffering from acute chest pain with normal hs-cTnI level,additional platelet PKCε detection appears to have a good prognostic gain.

Objective:To observe the improving effects of Tuina(Chinese therapeutic massage)plus exercise therapy on joint alignment and walking function in children with genu varum(GV).Methods:Sixty-six children with GV were divided into an exercise therapy group and a Tuina plus exercise therapy group using the random number table method,with 33 cases in each group.Both groups received identical exercise therapy,while the Tuina plus exercise therapy group was additionally offered Tuina manipulation treatment.The intervention course lasted 12 weeks in both groups.Before and after the intervention,the three-dimensional gait analysis was adopted to assess the spatiotemporal parameters,kinematics,and kinetic characteristics of lower-limb joints in children with GV.Results:The GV angle was reduced after intervention in the Tuina plus exercise therapy group(P<0.05),but there was no significant change in the exercise therapy group(P>0.05).After treatment,the Tuina plus exercise therapy group demonstrated a notable decrease in the step length,walking speed,peak forefoot adduction angle,and peak ankle inversion moment(P<0.05),suggesting the correction of the ankle joint's compensatory pathological changes.In the exercise therapy group,the foot progression angle(FPA)and gait deviation index(GDI)increased markedly after the intervention(P<0.05),indicating improved overall kinematic function.Conclusion:The combined use of Tuina manipulations and exercise therapy can produce significant effects in correcting the knee joint's torsion,both coronally(GV angle)and horizontally(ankle inversion moment,FPA,and forefoot adduction angle),while exercise therapy alone can markedly improve the overall kinematic parameters(FPA and GDI).
