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.

AIM:To investigated the mechanism of action of Yiqi tongfu xiere prescription(YTX)in treating mice with lipopolysaccharide(LPS)-in-duced acute lung injury(ALI).METHODS:According to the random number table,24 C57BL/6 mice were divided into 4 groups:control group(Control),model group(LPS),low dose group(YTX-L)and high dose group(YTX-H).Except for the control group,the mice models of acute lung injury were established by intratracheal instillation of LPS solu-tion(5 mg/kg).The low and high dose treatment groups were given intragastric administration con-tinuously for 14 days.After 24 hours,the lung tis-sue,bronchoalveolar lavage fluid(BALF)and serum of the four groups were taken for follow-up detec-tion.The degree of pulmonary edema was evaluat-ed by wet weight coefficient(wet to dry ratio,W/D)of lung tissue.The degree of alveolar inflamma-tion and pulmonary fibrosis were evaluated by HE and Masson staining,and the contents of BALF and serum inflammatory cytokines IL-1β and IL-6 were detected by ELISA.The protein expressions of α-SMA,FN,Col-Ⅰ and Col-Ⅲ were measured by West-ern blot.Determination of α-SMA,FN,Col-Ⅰ,MAPK,NF-κB mRNA expression by RT-PCR method.RE-SULTS:Compared with LPS group,the contents of BALF,IL-1β and IL-6 in serum,Wmax D ratio,lung pathology,serum α-SMA,FN,Col-Ⅰ,Col-Ⅲ protein expression and α-SMA,FN,Col-Ⅰ,MAPK,NF-κB mRNA expression in treatment group were signifi-cantly lower than those in control group.CONCLU-SION:YTX can significantly reduce the levels of pul-monary fibrosis markers such as α-SMA,FN,Col-Ⅰand Col-Ⅲ by inhibiting the activation of MAPK/NF-κB signal pathway,and improve alveolar inflamma-tion and pulmonary fibrosis in mice with lung inju-ry,suggesting that YTX can treat acute lung injury and provide a theoretical basis for the clinical use of YTX.

Objective:To analyze the correlation between serum uric acid-to-high-density lipoprotein cholesterol ratio (UHR) and risk of all-cause death or cardiovascular disease (CVD) death among urban and rural elderly in Beijing.Methods:Based on the Beijing Healthy Aging Cohort Study, 9 022 participants with complete baseline data were enrolled, and their survival and death outcomes were followed up. Multivariable Cox proportional hazard regression model were used to analyze the associations between the UHR level and the risks of all-cause mortality and CVD mortality.Results:As of March 31, 2021, the median follow-up time M( Q1, Q3) was 6.18 (5.36, 6.75) years. There were 1 166 all-deaths, with a death density of 19.26 per 1 000 person-years, and 562 CVD deaths, with a death density of 9.28 per 1 000 person-years. After adjusting sociodemographic characteristics and lifestyle factors, multivariable Cox proportional hazard regression model showed that the risk of all-cause mortality increased by 3% ( HR=1.03, 95% CI: 1.02-1.04) and the risk of CVD mortality increased by 4% ( HR=1.04, 95% CI: 1.02-1.06) for every 1% increase in UHR. Compared with the T1 group of UHR tertiles, the T3 group had a 42% increase in the risk of all-cause death ( HR=1.42, 95% CI: 1.22-1.66) and a 53% increase in the risk of CVD death ( HR=1.53, 95% CI: 1.21-1.94). Conclusions:The UHR level is significantly associated with the risks of all-cause mortality and CVD mortality among urban and rural older adults in Beijing. The UHR level may be one of the potential predictors of death risk in community-dwelling older adults.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To develop a rapid assessment scale for healthy aging suitable for the Chinese population.Methods:Based on existing healthy aging assessment scales, national standards, and expert consensus, an initial Healthy Aging Rapid Assessment Scale was drafted through two rounds of expert consultation. A pre-survey was conducted with 3 220 subjects recruited from Guangzhou between July 2023 and July 2024. Items were screened through item analysis and exploratory factor analysis to form the final scale. Reliability and validity of the final scale were validated across five cities: Guangzhou, Dongguan, Shenzhen, Baoding, and Chuxiong.Results:The initial version comprised 36 items, while the finalized scale contained 18 items across three dimensions: metabolic health, mental health, and cognitive health. Test-retest reliability ranged from 0.71 to 0.81 across all study sites. The Spearman-Brown coefficient varied between 0.91-0.96, Cronbach′s α between 0.77-0.83, comparative fit index (CFI) between 0.90-0.98, goodness-of-fit index (GFI) between 0.90-0.99, and root-mean-square error of approximation (RMSEA) between 0.03-0.09. For the three dimensions, reliability and validity metrics demonstrated consistency: Spearman-Brown coefficients 0.87-0.99, Cronbach′s α 0.77-0.83, CFI 0.90-0.98, GFI 0.90-0.99, and RMSEA 0.03-0.09 across four regions.Conclusion:The developed Healthy Aging Rapid Assessment Scale for the Chinese population exhibits robust reliability and validity.

Objective:To analyze the effect of meridian scraping combined with thunder fire moxibustion in improving the motor function and hemorheology of patients with shoulder hand syndrome (SHS) after ischemic stroke, in order to provide reference for clinical intervention of SHS patients after ischemic stroke.Methods:A prospective study was conducted using a simple random sampling method to select SHS patients after ischemic stroke admitted to Shijiazhuang Hospital of Traditional Chinese Medicine from January 2020 to June 2023, and were randomly divided into two groups. The thunder-fire moxibustion group were given routine nursing and thunder-fire moxibustion therapy, and the combined group were additionally given scraping therapy along meridians on the basis of thunder-fire moxibustion group. The Upper Limb Fugl-Meyer Motor Function Assessment Scale (U-FMA) score, Visual Analogue Scale (VAS) score, Action Research Arm Test (ARAT) score, shoulder joint activity score, hemorheological indicators (hematocrit, plasma viscosity, platelet adhesion rate) and activities of daily living (Barthel Index), etc. were compared between two groups before and after intervention.Results:Finally, 86 patients with SHS after ischemic stroke were included, with 42 patients in the thunder-fire moxibustion group, including 25 males and 17 females, aged (59.37 ± 7.64) years; 44 patients in the combined group, including 24 males and 20 females, aged (59.52 ± 7.61) years. Before intervention, there was no statistical significance in U-FMA score, VAS score, ARAT score, shoulder joint activity score, hemorheology index level and Barthel Index between two groups (all P>0.05). After intervention, the U-FMA score, ARAT score and Barthel Index in the combined group were (48.21 ± 4.85), (40.22 ± 4.64), (56.43 ± 9.76) points, respectively, which were higher than (44.56 ± 4.23), (35.98 ± 4.37), (51.97 ± 8.31) points in the thunder-fire moxibustion group, the differences were statistically significant ( t =3.71, 4.36, 2.28, all P<0.05). The VAS score, shoulder joint mobility score, blood cell volume, plasma viscosity and platelet adhesion rate in the combined group were (2.44 ± 0.87) points, (1.23 ± 0.25) points, 0.44 ± 0.02, (1.35 ± 0.32) mPa·s, (53.56 ± 5.71)%, respectively, which were lower than (3.05 ± 0.99) points, (1.58 ± 0.22) points, 0.46 ± 0.02, (1.72 ± 0.36) mPa·s, (62.53 ± 5.94)% in the thunder-fire moxibustion group, the differences were statistically significant ( t values were 3.04-7.14, all P<0.05). Conclusions:Scraping along meridians combined with thunder-fire moxibustion therapy can achieve good intervention effect in patients with SHS after ischemic stroke, improve the upper limb motor function and hemorheology of patients, and enhance the activities of daily living.

Objective To explore the effects of ultrasound-guided intercostal nerve block(INB)and thoracic paravertebral nerve block(TPVB)on the dosage of anesthetics and the efficacy of analgesia in video-assisted thoracoscopic lobectomy.Methods From October 2019 to October 2023,90 patients undergoing video-assisted thoracoscopic lobectomy at the People's Hospital of Tongling City,Anhui,were selected.They were divided into the INB group(42 cases)and the TPVB group(48 cases).The INB group received ultrasound-guided intercostal nerve block,while the TPVB group was administered ultrasound-guided thoracic paravertebral nerve block.The two groups were compared before anesthesia induction(T0),15 minutes of anesthesia(T1),30 minutes of anesthesia(T2),45 minutes of anesthesia(T3),and after extubation(T4),vita4 signs,anesthetic dosage,analgesic effect,pain stress index and adverse reactions.Results In the TPVB group,systolic blood pressure(SBP)of T1,T2,T3 and T4 were(115.88±9.29)mmHg,(113.58±9.72)mmHg,(117.33±9.17)mmHg and(121.15±10.51)mmHg,respectively;diastolic blood pressure(DBP)were(86.74±7.35)mmHg,(90.83±8.82)mmHg,(90.83±8.82)mmHg and(91.05±8.73)mmHg,respectively;Heart rate(HR)were(79.94±7.46)times/min,(81.97±7.28)times/min,(82.36±7.41)times/min and(85.83±8.32)times/min,respectively.Which were all higher than the INB group[(103.53±8.28)mmHg,(105.40±8.66)mmHg,(109.03±8.13)mmHg,(114.64±9.65)mmHg.(77.68±6.57)mmHg,(79.27±6.69)mmHg,(83.21±7.37)mmHg,(85.83±8.21)mmHg,(71.17±6.21)times/min,(75.18±6.47)times/min,(74.82±6.12)times/min and(79.35±7.12)times/min,respectively],there were statistical significance between the two groups(P＜0.05).Postoperatively,the TPVB group had lower 24-hour sufentanil consumption[(27.68±2.64)μg]and fewer presses of the analgesia pump[(5.16±0.38)times]compared to the INB group[(36.22±3.36)μg and(6.87±0.42)times,(P＜0.05)].Visual analogue scale(VAS)scores for pain at rest and during coughing at 2,24,and 48 hours in group TPVB were 2.44±0.27,3.55±0.42,2.81±0.34 and 3.36±0.23,4.13±0.33,3.80±0.25,respectively,which were also lower than the INB group(2.83±0.44,3.98±0.55,3.33±0.46 and 3.87±0.30,4.59±0.47,4.17±0.29,respectively)(P＜0.05).Levels of prostaglandin E2(PGE2)(1.53±0.28 μg/L),norepinephrine(NE)(362.25±33.85 ng/L),and cortisol(Cor)(278.72±25.13 ng/L)in the TPVB group were lower than those in the INB group(2.71±0.32 μg/L,425.67±38.37 ng/L,315.68±29.21 ng/L)(P＜0.05).Adverse reactions such as nausea and vomiting,and dizziness were less frequent in the TPVB group[1(2.1％),1(2.1％)]compared to the INB group[6(12.5％),5(10.4％)](P＜0.05).Conclusion Ultrasound-guided thoracic paravertebral nerve block is superior to intercostal nerve block in terms of anesthetic dosage and analgesic efficacy in video-assisted thoracoscopic lobectomy.
