Esophageal cancer is a prevalent malignant tumor of the digestive tract in China, and radical surgery remains the cornerstone of its comprehensive treatment. However, multifactorial challenges such as postoperative gastrointestinal tract reconstruction, traumatic stress, and tumor-related metabolic disturbances render esophageal cancer patients highly susceptible to malnutrition. Perioperative nutritional support therapy plays a crucial role in enhancing surgical safety, improving clinical outcomes, and elevating patients' quality of life by regulating metabolic homeostasis, preserving organ function, and optimizing the immune microenvironment. This article reviews the mechanisms underlying malnutrition in esophageal cancer, methods for nutritional status assessment, and precision intervention pathways based on multi-omics evaluations. The aim is to strengthen clinicians' awareness of standardized perioperative nutritional management for esophageal cancer patients and promote its clinical implementation, thereby facilitating postoperative recovery and improving long-term quality of life.

OBJECTIVE: To investigate the clinical efficacy of moxibustion (Mox) combined with low-dose tadalafil (TAD) in the treatment of diabetes mellitus-induced erectile dysfunction (DMED) with the syndrome of Qi deficiency and blood stasis. METHODS: According to the inclusion and exclusion criteria, we selected 90 patients with DMED for this trial and equally randomized them into a Mox, a TAD, and a Mox combined with TAD (Mox+TAD) group to be treated by mild Mox applied to the acupoints Zusanli, Sanyinjiao and Yinlingquan qd alt, oral medication with low-dose TAD at 5 mg per dose qd, and combination of the above two therapies, respectively, all for 4 weeks. We obtained from the patients their IIEF-5 scores, traditional Chinese medicine (TCM) symptoms scores, Erectile Hardness Scale (EHS) scores, corpus cavernosal hemodynamic indexes, and the peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI) of the corpus cavernosal arteries before and after treatment, and compared them among the three groups. RESULTS: The total effectiveness rate was significantly higher in the Mox+TAD (90.0%) than in the Mox (46.7%) and TAD groups (60.0%) (P< 0.05). Compared with the baseline, the IIEF-5 and EHS scores were increased, while the TCM symptoms scores decreased in all the three groups after treatment, more significantly in the Mox+TAD group than in the other two (P< 0.05). And the PSV and RI were remarkably increased, while the EDV decreased (P< 0.05) in all the three groups (P< 0.05) after treatment, with PSV even higher in the Mox+TAD than in the Mox and TAD groups (P< 0.05). CONCLUSION Moxibustion combined with tadalafil has a definite efficacy and safety for the treatment of DMED, which can effectively improve the erectile function of the patients by increasing penile blood supply, benefiting qi and activating blood circulation.

Aim To investigate the therapeutic effects of a newly developed Tadalafil tablets on pathological myocardial hypertrophy induced by abdominal aortic constriction(AAC)in rats,as well as its influence on the activation of the NF-κB signaling pathway in myo-cardial cells.Methods SD rats were randomly divid-ed into 4 groups:the sham operation group(Sham),the model group(AAC),the tadalafil new tablet treat-ment group(N-Tad,5 mg·kg-1),and the positive control drug treatment group(Cialis,10 mg·kg-1g).The AAC model group and treatment group rats under-went blunt dissection and constrictive ligation of the abdominal aorta at the left renal artery branch point during surgery,while the Sham group rats only had their arteries separated without any constrictive liga-tion.Rats in the treatment groups received either N-Tad or Cialis via gavage three days after modeling,while rats in the sham group and the model group re-ceived physiological saline daily for 8 weeks.Small an-imal ultra-high-resolution echocardiography and hemo-dynamic assessment were applied to evaluate left ven-tricular function in each group of rats,and the calcula-tion of the left ventricular mass index was conducted.By employing Western blot and RT-PCR.we assessed the impact of this treatment on the expression of the hy-pertrophy factor atrial natriuretic peptide(ANP),phosphorylated NF-κB p65 protein(p-NF-κB p65),and phosphorylated IκB-α in the left heart tissue of rats and in H9c2 cardiomyocytes.Results Compared to the Sham group,the AAC rats exhibited a significant decrease in left heart function,an increase in left ven-tricular mass index,and a notable increase in ANP and p-p65 expression in the left heart tissue(P＜0.05).Both N-Tad and Cialis treatments could significantly enhance left ventricular function,decrease left ventric-ular mass index,and inhibit the expression of ANP and phosphorylated NF-κB p65 in rats with myocardial hy-pertrophy(P＜0.05).Notably,the therapeutic effect of low-dose N-Tad was comparable to that of high-dose Cialis.At the cellular level,Tadalafil significantly in-hibited the activation of the NF-κB signaling pathway and reduced the expression of associated proteins in H9c2 cardiomyocytes.Conclusions N-Tad can sig-nificantly inhibit p65 and IκB-α phosphorylation,and the activation of the NF-κB signaling pathway,reduce ANP expression,and improve pathological myocardial hypertrophy,as well as mitigate left heart function damage caused by abdominal aortic constriction.

Objective To analyze the application effect of blunt dissection for myotomy of incision in single-port thoracoscopic lung wedge resection.Methods Patients who underwent single-port thoracoscopic lung wedge resection in our hospital from January to June 2024 were selected and divided into the observation group(32 cases,received blunt dissection for myotomy of incision during the surgery)and the control group(35 cases,received electrosurgical knife for myotomy of incision during the surgery)according to random number table method.The anesthesia time,operation time,intraoperative blood loss,the earliest time to get out of bed after the operation,the dosage of dezocine,and the resting and cough visual analogue scale(VAS)scores in each postoperative period of patients in the two groups were compared.Results There was no significant difference in terms of anesthesia time,operation time,intraoperative blood loss,or dosage of dezocine of patients between the two groups(P>0.05).The earliest time to get out of bed after operation of patients in the observation group was shorter than that in the control group,with significant difference(P<0.05).No significant difference was observed in resting VAS scores 6 hours or 12 hours after operation of patients in both two groups(P>0.05),but significant differences were found in resting VAS scores 24 hours and 48 hours after operation between the two groups(P<0.05).No significant difference was found in cough VAS scores 6 hours after operation of patients between the two groups(P>0.05),but significant differences were observed in cough VAS scores 12 hours,24 hours,and 48 hours after operation between the two groups(P<0.05).Conclusion Compared with electrosurgical knife for myotomy of incision,blunt dissection for myotomy of incision in single-port thoracoscopic lung wedge resection can reduce postoperative pain,promote postoperative ambulation for patients,which is beneficial to postoperative recovery.

Objective To investigate the value of serum lipoprotein-associated phospholipase A2(Lp-PLA2)for predicting high-risk coronary plaques in elderly males.Methods A retrospective study was conducted on 46 elderly males aged ≥60 years undergoing health check-ups and coro-nary computed tomography angiography in our hospital between May and July 2024.Their general clinical data were collected.Artificial intelligence software was used to analyze coronary calcium scores and plaque characteristics.The participants were divided into a high-risk plaque group(n=15)and a non-high-risk plaque group(n=31).The differences were compared between the two groups.Multivariate logistic regression analysis was used to identify the influencing factors for high-risk coronary plaques.ROC curve was plotted to determine the predictive value of serum Lp-PLA2 for high-risk plaques,and its AUC value was calculated.Results The high-risk plaque group had significantly larger proportions of smoking history and hyperlipidemia,and higher level of homocysteine and Lp-PLA2 than the non-high-risk plaque group(P＜0.05,P＜0.01).Multiva-riate logistic regression analysis indicated that Lp-PLA2 was an independent risk factor for high-risk coronary plaques(HR=1.030,95％CI:1.008-1.053,P＜0.05).ROC curve analysis revealed that the AUC value of Lp-PLA2 in predicting high-risk coronary plaques was 0.833(95％CI:0.694-0.927,P＜0.01),with a sensitivity of 93.3％,a specificity of 71.0％,a positive predictive value of 62.5％,and a negative predictive value of 100％.Conclusion Serum Lp-PLA2 is of signif-icant value in predicting high-risk coronary plaques in elderly men.

Objective:To investigate the predictive value of measured cardiac power output(CPO)of echocardiography for the prognosis of elderly patients with acute heart failure(AHF)in the vulnerable period of heart failure.Methods:A total of 120 elderly patients with AHF who admitted to the Third Hospital Affiliated to Shanxi Medical University from January 2021 to January 2024 were selected,and they were divided into the major adverse cardiovascular events(MACE)group(18 cases)and the non-MACE group(102 cases)according to whether occurred MACE in the vulnerable period within 3 months after discharge.The baseline data of the two groups of patients were compared.Logistic regression was used to analyze the influencing factors of occurring MACE in the vulnerable period of patients,and the receiver operating characteristic(ROC)curve was used to analyze the predictive value of CPO for MACE in the vulnerable period of heart failure in elderly patients with AHF.Results:In the baseline data of patients,the total cholesterol,25-hydroxyvitamin D[25(OH)D],reserve CPO,resting CPO,and peak CPO in the MACE group were all lower than those in the non-MACE group,and the differences were statistically significant(t=5.987,2.236,2.921,2.390,4.569,P<0.05).The levels of brain natriuretic peptide(BNP)and N-terminal pro-brain natriuretic peptide(NT-proBNP)in the MACE group were higher than those in the non-MACE group,and the differences were statistically significant(t=22.074,23.368,P<0.05).The results of Logistic regression analysis showed that the total cholesterol,25(OH)D,reserve CPO,resting CPO,and peak CPO were all influencing factors for the occurrence of MACE during the vulnerable period of heart failure in patients(OR=0.064,0.942,0.015,0.035,0.041,P<0.05).ROC curve analysis showed that the efficacy of resting CPO and reserve CPO of the cardiac function indicators in predicting MACE of patients were slightly lower than that of peak CPO.The AUC,sensitivity and specificity of peak CPO in predicting MACE of patients were 0.752,92.2%and 55.6%,respectively.Conclusion:The lower peak CPO value of cardiac function indicator of echocardiography is independent risk factor for MACE during the vulnerable period of heart failure in elderly patients with AHF.Measuring CPO can identify potential poor prognosis populations in advance.

Nitrogen dioxide(NO 2)is a prevalent air pollutant that poses significant threats to the environment and human health,emphasizing the urgent need for high-performance NO 2 sensors for effective environmental monitoring at room temperature.Sensors based on metal halide perovskites have emerged as promising candidates for gas detection at room temperature,but their long-term stability remains a major challenge.In this study,a methylamine thiocyanate(MT)-doped FA 0.8Cs 0.2PbI 2Br(PVK)gas sensor(MT-PVK)was prepared using a simple one-step spin-coating method and ethyl acetate(EA)anti-solvent extraction technique.The crystalline structure,chemical composition,and particle morphology of the MT-PVK thin film were characterized.The MT-PVK thin film was then utilized as a gas sensor for NO 2 detection at room temperature.The results demonstrated that the sensor exhibited outstanding selectivity and reversibility at low concentrations of NO 2 gas,with a detection limit as low as 33 ppb(10-9,nL/L).For 10 ppm(10-6,μL/L)NO 2,the sensor showed rapid response and recovery time of only 1.6 s and 27 s,outperforming most traditional metal oxide NO 2 sensors.Furthermore,compared to the original PVK,the MT molecules significantly enhanced the structural and sensing stability of the MT-PVK sensor under high humidity conditions(55%±5%).These findings suggested that MT-doped FA 0.8Cs 0.2PbI 2Br perovskite gas sensors offered a promising pathway for the development of rapid-response gas sensing technologies suitable for room temperature operation.

Objective To investigate the antitumor effects of triptolide against CT26 colon cancer and its impact on the expression of Polo-like kinase-1(PLK-1)protein.Methods Forty clean grade BALB/c mice,each mouse was implanted with 1×106 CT26 cells into the dorsal side of the right forelimb to establish a tumor-bearing mouse model.Experimental animals were randomly divided into four groups,the tumor model group(saline control),the positive drug group[oxaliplatin,5 mg/(kg·d)],the low-dose triptolide group[50 μg/(kg·/d)],and the high-dose triptolide group[100 μg/(kg·d)].The drugs were administered through intraperitoneal injection(10 times in total,once every other day).The in vitro effects of the drugs on the proliferation,migration,invasion,and mitosis of CT26 cells were also assessed.Results Triptolide significantly inhibited the proliferation,migration,and invasion of CT26 colon cancer cells,and disrupted the separation of centrosomes and the correct arrangement of chromosomes during the prophase of mitosis in tumor cells.The binding energy of triptolide and PLK-1 protein was-7.1 kcal/mol,and it could down-regulate the expression of PLK-1 in CT26 cells.Conclusion Triptolide exerts its antitumor effects against CT26 colon cancer by downregulating the expression of PLK-1.

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: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.
