[摘 要] 目的：探讨m6A调控因子在宫颈癌预后评估、免疫微环境特征及治疗反应中的作用，构建基于m6A调控因子的预后风险模型，并分析其与免疫浸润、药物敏感性及细胞间通信的关系。方法：基于TCGA和GEO数据库中宫颈鳞癌及腺癌（CESC）转录组数据，分析22个m6A调控因子的表达与突变情况；采用LASSO‑Cox回归构建m6A相关预后风险模型，并依据风险评分将患者分为高、低风险组。利用CIBERSORT和ESTIMATE算法评估两组免疫细胞浸润及微环境特征；通过oncoPredict预测抗肿瘤药物敏感性。整合单细胞转录组数据（E-MTAB-12305），采用CellChat分析细胞间通信网络。结果：共鉴定出12个在宫颈癌中差异表达的m6A调控因子。高风险组患者总生存期缩短（P < 0.05），免疫评分降低，且对紫杉醇、氟尿嘧啶、多柔比星等抗肿瘤药物敏感性较差（IC50较高）。单细胞分析显示宫颈癌组织中细胞间通信网络发生改变，其中T细胞与内皮/上皮细胞间的相互作用可能主要由CCL5‑ACKR1和MIF‑（CD74 + CXCR4）配体‑受体介导。在临床样本中，对关键的m6A调控因子进行mRNA和蛋白水平的验证，结果显示部分调控因子在宫颈癌组织中的表达水平高于正常宫颈组织（P < 0.05）。结论：m6A调控因子特征可有效预测宫颈癌患者预后，其风险评分与肿瘤免疫浸润、药物敏感性及细胞通信密切相关，为宫颈癌的预后分层及个体化治疗提供了新的分子依据。

Objective:To explore the application effect of health education path management model based on cloud platform in the perioperative period of patients with atrial fibrillation (AF), and analyze the feasibility of innovative education forms.Methods:Adopting a non synchronous historical control study design.A total of 291 patients who underwent transcatheter radiofrequency ablation in Fuzhou University Affiliated Provincial Hospital from January to June 2023 were selected by convenience sampling. To avoid contamination of research subjects by grouping them according to admission time, 144 patients admitted from January to March 2023 were used as the control group, and 147 patients admitted from April to June 2023 were used as the intervention group.The control group adopted the traditional health education method, and the intervention group adopted the health education path management mode based on the cloud platform.The postoperative recovery (length of hospital stay, time out of bed, surgical complications), the first postoperative bed urination, the degree of health knowledge related to atrial fibrillation, and the patient satisfaction were compared between the two groups.Results:There were 101 males and 43 females in the control group, was (61.74 ± 10.63) years old, and 103 males and 44 females in the intervention group, was (62.93 ± 8.79) years old.After the intervention, the hospitalization time of the intervention group was (4.25 ± 1.00) days, which was shorter than that of the control group (6.23 ± 1.16) days, and the difference was statistically significant ( t=5.92, P<0.05). The time of getting out of bed after operation in the intervention group was (6.69 ± 0.84) hours, which was earlier than that in the control group (12.69 ± 1.51) hours, and the difference was statistically significant ( t=25.68, P<0.05). There were 134 cases of no complications in the intervention group and 9 cases of subcutaneous hematoma, 2 cases of medical viscose-related skin injury, 1 case of pneumothorax/hemothorax, and 1 case of acute cerebrovascular event occurred, there were 113 cases of no complications in the intervention group, which had 16 cases of subcutaneous hematoma, 2 cases of medical viscose-related skin injury, 11 cases of pneumothorax/hemothorax, and 2 cases of acute cerebrovascular event, the difference was statistically significant ( χ2=12.38, P<0.05). There were 119 cases of spontaneous urination, 17 cases of dysuria and 11 cases of urinary retention in the intervention group, which were lower than 100 cases of spontaneous urination, 13 cases of dysuria and 31 cases of urinary retention in the control group, the difference was statistically significant ( χ2=11.68, P <0.05). Score of the health knowledge score of AF in the intervention group was (21.49 ± 0.16) points, which was higher than the control group's score of (18.30 ± 0.20) points, and the difference was statistically significant ( t=12.50, P<0.05). The satisfaction of intervention group's score was (20.12 ± 1.93) points, which was higher than the control group's score of (15.10 ± 3.13) points, and the difference was statistically significant ( t=16.51, P<0.05).

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 investigate intraoperative pathological findings and the interventional effects of "deep cervical lymphaticovenous anastomosis+" (dcLVA+) on deep cervical lymphatic drainage as well as the blood flow of carotid artery and jugular vein in elderly patients with cognitive impairment, and to put forward the thoughts based on the findings from the surgery.Methods:Between May 2024 and December 2024, retrospective analysis of Microsurgery Hospital, Fengcheng Hospital, Xi'an Medical College performed dcLVA+ between the deep cervical lymphatics or lymph nodes and jugular veins in 50 elderly patients with cognitive impairment (19 males and 31 females, aged 55-88 years with 69.94 years in average). Nine patients were found with Clinical Dementia Rating (CDR) score at 1 (mild), 7 with CDR score at 2 (moderate) and 34 with CDR score at 3 (severe). Intraoperative observations based on literature reviews had identified anatomical relationships between the lymphatic sacs containing cervical lymphatic chain and the carotid sheath. The lymph node count, size, distribution, thickness of fat tissue and conditions of lymphatic vessels were documented. Ultrasound was used to compare the blood flow of carotid artery and jugular vein as well as the cross-sectional areas at the planes of hyoid and cricoid cartilage before and after the closure of incisions under anaesthesia in 39 patients. Correlation analyses for Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCa), Activities of Daily Living (ADL) and Agitation behavior score before and 1 week after surgery were performed using Spearman's correlation and Wilcoxon paired tests. P<0.05 was considered statistically significant. Postoperative follow-ups were conducted via the visit of outpatient clinic and WeChat and telephone interviews. Results:In surgery, the cervical lymphatic chain was found running within an almost enclosed sac surrounding the carotid sheath. There were enlarged lymph nodes, increased fat deposition, lymphatic dilation or fibrosis in the sac. The preoperative blood flow in the carotid artery at the planes of hyoid and cricoid cartilage in the 39 patients was recorded at 150.52 ml/min±40.33 ml/min and 358.29 ml/min±129.30 ml/min, while that in the jugular vein was at 172.50 ml/min±63.94 ml/min and 317.00 ml/min±105.21 ml/min, respectively, both were far lower than the normal blood flow. There were statistically significant differences in the blood flow of carotid artery and jugular vein before and after surgery ( P<0.01). It was found that the preoperative blood flow of the internal carotid artery at the plane of hyoid was positively correlated with the preoperative scores of MMSE ( P<0.01), MoCa ( P<0.05) and ADL ( P<0.01). The blood flow of the common carotid artery at the plane of cricoid cartilage was found significantly and positively correlated with the preoperative scores of MMSE ( P<0.05). It was also noted that the blood flow of the internal carotid artery at the plane of hyoid was significantly and positively correlated with the postoperative ADL ( P<0.01) but negatively correlated with the Agitation behavior score ( P<0.05). The blood flow of the common carotid artery at the plane of cricoid cartilage was significantly and positively correlated with the postoperative scores of MMSE and MoCa ( P<0.05). The blood flow of the internal jugular vein at the plane of hyoid was negatively correlated with the Agitation behavior score ( P<0.01). The cross-sectional area of carotid artery at the plane of left hyoid was significantly and positively correlated with the MMSE score ( P<0.05). Statistically significant differences were observed in MMSE, MoCa, ADL and Agitation behavior score before and after surgery ( P<0.01). Conclusion:dcLVA+ shows a certain therapeutic benefit to the elderly patients with cognitive impairment. The intraoperatively observed pathological changes in cervical lymphatic sacs affect deep cervical lymphatic drainage and the blood flow of carotid artery and jugular vein. Further studies are necessary to find out whether the findings from this study would be the specific pathological changes and the morbidity mechanisms among the elderly patients with cognitive impairment.

Objective:To explore the clinical features of Brucellar myelitis and diagnosis and treatment of secondary neuromyelitis optica spectrum disorder (NMOSD), and enhance the awareness of clinicians about this disease.Methods:A retrospective study was performed; 13 patients with Brucellar myelitis admitted to Department of Neurology, Inner Mongolia Autonomous Region People's Hospital from January 2020 to December 2024 were chosen. Clinical data were collected, and MRI images and serological changes during the infection period were observed. Serum and cerebrospinal fluid demyelinating antibody markers and cerebrospinal fluid oligoclonal bands (OCBs) in the suspected secondary inflammatory demyelinating diseases of the central nervous system patients were detected. All patients received standard antibiotic treatment and/or individualized immunotherapy depending on disease severity. The patients were followed up for 24 (12, 42) months. At the last follow-up, the neurological outcomes were evaluated using modified Rankin scale (mRS, scores of 0-2: good prognosis; scores of 3-6: poor prognosis).Results:(1) Among the 13 patients, 12 had motor disorder, 9 had bladder/bowel dysfunction, 7 had sensory abnormality, and 4 had other symptoms such as dizziness, behavioral changes, or unsteady gait. (2) MRI results showed that 8 patients had spinal cord abnormalities, including 2 with long-segment intramedullary high signal at T2-weighted image and 6 with short-segment local intramedullary high signal at T2-weighted image. Enhanced MRI was performed in 11 patients, with 2 showing lesion enhancement, 3 showing meningeal enhancement, and 6 showing no enhancement. (3) Four patients had elevated cerebrospinal fluid pressure (>180 mmH 2O); 9 patients had elevated cerebrospinal fluid protein level (>0.45 g/L). Brucella-specific DNA was detected in the cerebrospinal fluid of 6 patients. One patient was positive for OCB type II. One patient was positive for aquaporin 4 antibody (AQP4-IgG) in both serum and cerebrospinal fluid, and one patient was double positive for myelin oligodendrocyte glycoprotein antibody (MOG-IgG) and AQP4-IgG in serum. (4) All 13 patients received standard antibiotic treatment; 12 patients received immunotherapy. (5) Among the 4 patients with poor prognosis, 3 died and the remaining 9 had a good prognosis. The mRS score decreasing from 4 (3, 4) at admission to 2 (2, 3) at the last follow-up, showing an overall improvement in neurological function. (6) Among the 13 patients, 2 were diagnosed as having Brucellar myelitis secondary NMOSD. On the basis of antibiotic treatment, one AQP4-IgG positive patient was treated with high-dose glucocorticoids only and later died; one MOG-IgG and AQP4-IgG double positive patient was treated with intravenous immunoglobulin combined with high-dose glucocorticoids and sequential rituximab, with mRS score decreasing from 5 at admission to 2 at the last follow-up and good neurological function recovery. Conclusions:The clinical manifestations of Brucellar myelitis are diverse and overlap with the clinical features of NMOSD. For patients with suspected Brucellar myelitis secondary NMOSD, combination of immunosuppressant (such as rituximab) with antibiotics may be an effective individualized treatment.

Objective To evaluate the effectiveness and feasibility of a remote medication treatment management model for elderly patients with chronic disease at home based on mobile technology.Methods A convenient and elderly-friendly mo-bile application(hereinafter referred to as Yaoshiyi APP)was developed,and a remote medication treatment management team consisting of clinical pharmacists from tertiary hospitals,community pharmacists,and community physicians was formed.Patients from communities were selected for practical research,led by pharmacists.Based on the Yaoshiyi APP,patients were subjected to 6 months of medication treatment management practice,and the effectiveness and feasibility of the practice were evaluated.Re-sults The Yaoshiyi APP can be integrated with a variety of medical-grade wearable devices to realize the functions of automati-cally uploading monitoring data,abnormal value reminding,medication reminding,medication consultation,and medication sci-ence popularization.A total of 302 elderly patients with chronic disease at home completed the study.The results showed that phar-macists have identified and intervened in 695 cases of medication-related problems.According to the classification of medication-related problems,the top three were 247 cases(35.5％)of additional treatment,97 cases(14.0％)of unnecessary drug treat-ment,and 93 cases(13.4％)of medication compliance problems.The patient's medication adherence score(Morisky medication adherence scale-8,MMAS-8)increased from(5.85±1.57)at enrollment to(6.74±1.23)6 months after enrollment(P＜0.01).After 6 months of enrollment,the patient's satisfaction with the pharmacist's work reached a score of(4.99±0.08)out of 5.The average reduction in drug costs for patients caused by pharmacists intervening in irrational medication is(20.9±18.0)％.At the end of follow-up,93.4％of patients were proficient in using the Yaoshiyi APP.Conclusion The remote medication treatment management model for elderly patients with chronic disease at home based on mobile technology constructed in this study can ef-fectively improve patient compliance with disease monitoring and medication,ensure rational drug use,reduce medical resource waste,and receive high patient acceptance.

Objective To explore the application effect of dexmedetomidine combined with ropivacaine for quadratus lumborum block at the lateral supra-arcuate ligament(QLB-LSAL) in open hepatocellular carcinoma resection.Methods A prospective study was conducted in 60 patients who underwent elective open hepatocellular carcinoma resection at Jining First People's Hospital. The patients were randomly divided into the compound group and the control group,with 30 cases in each group. Patients in the compound group received QLB-LSAL combined general anesthesia,and patients in the control group received simple general anesthesia. All patients underwent patient controlled intravenous analgesia (PCIA)postoperatively. The mean arterial pressure (MAP),heart rate (HR) and visual analogue scale (VAS) scores during rest and coughing at different time points were observed and compared between the two groups. The number of postoperative PCIA compressions,the dosage of sufentanil,the first postoperative exhaust time,the first postoperative ambulation time,the hospital stay and the occurrence of adverse reactions of the two groups were recorded. Results In the compound group,the HR and MAP were significantly lower than those of the control group at the time of skin incision (T2) and at the end of surgery (T3);the VAS scores during rest and coughing were significantly lower than those of the control group at the time of exiting the anesthesia recovery room and 6 hours and 12 hours after surgery;and the PCIA compression times were significantly less than those of the control group;the dosage of sufentanil was significantly lower than that in the control group 0 to 24 hours after surgery,and the dosage of sufentanil was higher than that in the control group 25 to 48 hours after surgery;the first postoperative ambulation time and the first postoperative exhaust time were significantly earlier than those in the control group;and the above differences were statistically significant(P<0.05). There was no significant difference in the HR or MAP at 5 minutes into the operating room (T0) and 5 minutes before skin incision (T1),VAS scores during rest and coughing 24 hours and 48 hours after surgery,hospital stay and incidence of adverse reactions between the two groups (P>0.05).Conclusion For patients with open hepatocellular carcinoma resection,dexmedetomidine combined with ropivazine for QLB-LSAL can provide more ideal postoperative analgesia,reduce perioperative opioid consumption,and have less impact on circulatory system,which is conducive to rapid postoperative recovery.

OBJECTIVE To construct a predictive tool for surgical site infections(SSIs)in spinal surgery for Chi-nese population to provide evidence support for reducing SSIs.METHODS A systematic review of Chinese and English database literature was conducted for Meta-analysis to obtain pooled risk values for influencing factors,and a risk prediction scoring tool was constructed based on the logistic regression model.Patients who underwent spinal surgery and completed postoperative follow-up in a tertiary hospital in Beijing from Jan.to Dec.2021 were selected to validate the predictive effect of the tool.RESULTS The predictive model for SSIs in Chinese spinal sur-gery patients was Logit(P)=—3.47+0.63(age 60 years)+0.31 ×(patient with cardiovascular disease)+0.69 ×(rheumatoid arthritis)+1.07 ×(diabetes)+1.06 ×(operation duration＞3 h)+1.17 ×(preopera-tive albumin＜35 g/L)+0.71 ×(history of spinal surgery)+0.67 ×(carrying internal implants)+0.73 ×(blood transfusion).The total score of the predictive tool was 92,with a cutoff score of≥24.50 indicating high-risk individuals.The area under the curve was 0.733,with the sensitivity 58.30％and the specificity 79.60％.CONCLUSION The established predictive model for SSIs in Chinese spine surgery demonstrates good predictive performance and can be used as a reference assessment tool in clinical practice.

Objective To establish a stable,reliable,and clinically relevant porcine model of endotoxin-induced acute respiratory distress syndrome(ARDS).Methods Ten 8-month-old male Bama minipigs were deeply sedated,followed by invasive mechanical ventilation and electrocardiographic monitoring.Lipopolysaccharide(LPS)was intravenously pumped at 600 μg/(kg·h)for 3 hours,then maintained at 15 μg/(kg·h)thereafter.Dynamic monitoring was performed at five time points after LPS injection(LPS 0,1,3,5,and 8 h),including arterial blood gas analysis and chest computed tomography(CT)scans.Pathological examination of lung tissues obtained via bronchoscopic biopsy(HE staining and transmission electron microscopy)was conducted.These indicators were comprehensively used to evaluate the success of the animal model.Results At 5 hours after LPS administration,8 minipigs developed symptoms such as skin cyanosis,elevated body temperature,and respiratory distress.The oxygenation index decreased to<300 mmHg.Chest CT scans showed diffuse pulmonary infiltrates.Histopathology revealed alveolar edema and hyaline membrane formation.Transmission electron microscopy demonstrated disruption of pulmonary blood-air barrier,depletion of lamellar bodies in type Ⅱ pneumocytes,inflammatory cell infiltration,and exudation of plasma proteins and fibrin.Compared with LPS 0 h,at LPS 8 h,the oxygenation index and arterial blood pH were significantly decreased(P<0.001),while blood lactic acid and serum potassium were significantly increased(P<0.05);serum calcium and base excess were significantly decreased(P<0.05),and the lung injury score based on HE-stained lung sections was significantly increased(P<0.01).Conclusion The porcine ARDS model established by continuous LPS injection can dynamically simulate the pathophysiological characteristics and typical pathological manifestations of clinical septic ARDS,making it an effective tool to study the pathogenesis,prevention,and treatment strategies of septic ARDS.
