Objective To analyze the influencing factors for postoperative anastomotic leak (AL) in carcinoma of the esophagus and gastroesophageal junction and construct a nomogram predictive model. Methods The patients who underwent radical esophagectomy at Jinling Hospital Affiliated to Nanjing University School of Medicine from January 2018 to June 2020 were included in this study. Relevant variables were screened using univariate and multivariate logistic regression analyses. A nomogram was then developed to predict the risk factors associated with postoperative AL. The predictive performance of the nomogram was validated using the receiver operating characteristic (ROC) curve. Results A total of 468 patients with carcinoma of the esophagus and gastroesophageal junction were included in the study, comprising 354 males and 114 females, with a mean age of (62.8±7.2) years. The tumors were predominantly located in the middle or lower esophagus, and 51 (10.90%) patients experienced postoperative AL. Univariate logistic regression analysis indicated that age, body mass index (BMI), tumor location, preoperative albumin levels, diabetes mellitus, anastomosis technique, anastomosis site, and C-reactive protein (CRP) levels were potentially associated with AL (P<0.05). Multivariate logistic regression analysis identified age, BMI, tumor location, diabetes mellitus, anastomosis technique, and CRP levels as independent risk factors for AL (P<0.05). A nomogram was developed based on the findings from the multivariate logistic regression analysis. The area under the receiver operating characteristic (ROC) curve was 0.803, indicating a strong concordance between the actual observations and the predicted outcomes. Furthermore, decision curve analysis demonstrated that the newly established nomogram holds significant value for clinical decision-making. Conclusion The predictive model for postoperative AL in patients with carcinoma of the esophagus and gastroesophageal junction demonstrates strong predictive validity and is essential for guiding clinical monitoring, early detection, and preventive strategies.

Objective:To observe the effect of reconstruction of Achilles insertion with Suture bridge technology after extirpation of avulsed bones block in the treatment of Beavis type Ⅲ avulsion fracture of the calcaneal tuberosity.Methods:The retrospective analysis was used. From January 2013 to January 2023, 78 patients with Beavis type Ⅲ avulsion fracture of the calcaneal tuberosity, treated in the Department 1 of Foot and Ankle and Department 2 of Foot and Ankle of the second Hospital of Tangshan were selected as research objects. According to different operation performed, 41 patients with the reconstruction of Achilles insertion with Suture bridge technology after extirpation of avulsed bones block were divided into the observation group and 37 patients with the open reduction internal fixation (ORIF) were divided into the control group. The delayed wound healing rate and the Haglund malformation rate, Maryland foot score, the American Orthopedic Foot and ankle Society (AOFAS) ankle-hindfoot score, the pain Visual Analogue Scale/Score (VAS) score, the Victorian Institute of Sports Assessment-Achilles (VISA-A) score, Arner-Lindholm scale of One-year postoperative were compared between these two groups. The measurement data with normal or approximate normal distribution were analyzed using t test, count data using chi-square test for comparison of between groups.Results:One year after surgery, the incidence of Haglund malformation in the observation group was 4.88% (2/41), which was lower than the control group's 29.73% (11/37). The difference between the two groups was statistically significant ( χ2=8.65,P=0.003). The excellent and good rate of Maryland foot function assessment in the observation group was 85.37% (35/41) higher than that in the control group (56.76% (21/37), and the difference between the two groups was statistically significant ( χ2=7.86, P=0.005). The AOFAS ankle hind foot score of the observation group ((90.44±6.66) points) was higher than that of the control group ((82.84±7.43) points), and the difference between the two groups was statistically significant ( t=4.77, P<0.001). The pain score of the observation group ((1.51±1.05) points) was lower than that of the control group ((2.95±1.13) points), and the difference between the two groups was statistically significant ( t=-5.81, P<0.001). The Achilles tendon score of the observation group ((81.05±5.87) points) was higher than that of the control group ((71.62±8.60) points), and the difference between the two groups was statistically significant ( t=5.70, P<0.001). The excellent and good rate of Arner Lindholm treatment efficacy evaluation for Achilles tendon in the observation group was 87.80% (36/41), which was higher than that in the control group (67.57% (25/37)), and the difference between the groups was statistically significant. Conclusion:The treatment of Beavis Ⅲ type calcaneal nodule avulsion fracture by removing the bone fragment can simultaneously remove the hypertrophic osteophyte, hardened bone, and Haglund deformity of the calcaneus, and clean the degenerated Achilles tendon and inflammatory tissue around the insertion point; The use of suture bridge technology to reconstruct the Achilles tendon insertion point has the advantages of high fixed strength, allowing early functional exercise, avoiding secondary removal of internal fixation, and achieving satisfactory therapeutic effects, which is worthy of clinical promotion.

To screen potential drugs for the treatment of acute Liver Injury(ALI)through network pharmacology and mitochondrial dynamics,and to investigate their actions and mechanisms.Based on the commonly utilized Liver Pure Tablets and Liver-Protecting Capsules in the market,a com-ponent library of liver disease drugs was screened and established.Pharmacological anchoring anal-ysis was carried out.Potential liver disease therapeutic drugs were screened out through molecular docking,and feedback verification was performed using animal experiments.Acute liver injury mouse models were established through excessive induction with acetaminophen(APAP),and the histopathological changes of liver tissues were examined.The protective effect of the drug on ALI was evaluated by detecting alanine aminotransferase(ALT),aspartate aminotransferase(AST),superoxide dismutase(SOD),catalase(CAT),glutathione(GSH),and malondialdehyde(MDA)using enzyme-linked immunosorbent assay(ELISA).qRT-PCR was employed to detect peroxi-some proliferator-activated receptor gamma coactivator 1-alpha(PPARG1A),mitofusin 1(MFN1),mitofusin 2(MFN2),dynamin-related protein 1(DRP1),optic atrophy 1 protein(OP A1),Steroid receptor coactivator(SRC),and advanced glycosylation end-product specific re-ceptor(AGER)to explore the protective mechanism of the drug on ALI.The result showed that Network pharmacology identified a total of 662 intersection targets of three types of prescription drugs and ALI.Eventually,72 core targets were screened out.Pathway enrichment analysis indi-cates that the potential mechanism might be associated with the lipid and atherosclerosis signaling pathways.The results of the relevant molecular docking indicate that the most likely optimal drug might be emodin(EMO).EMO ameliorated the pathological damage in mice with acute liver inju-ry,significantly decreased the contents of transferase factors ALT and AST,simultaneously in-creased the contents of antioxidant enzymes CAT,GSH and SOD,and reduced the content of oxi-dative metabolic end product MDA.It also upregulated the mRNA expression levels of MFN1、MFN2,OPA1,DRP1,SRC and PPARGC1A proteins in liver tissue,and inhibited the mRNA ex-pression level of AGER protein.The drug EMO,jointly screened out by network pharmacology through anchoring and molecular docking,might promote mitochondrial fusion metabolism,allevi-ate liver oxidative stress,and improve liver injury in ALI mice via the Lipid and atherosclerosis pathway.

Objective:To investigate the effects of combination therapy with aqueous extract of corn silk(CS)and training on exercise capacity and glycolipid metabolism in mice with metabolic syndrome(MS).Methods:In this study,db/db mice were used as the animal model of MS.The mice were administered aqueous extract of CS via gavage and subjected to different intensities of training for 12 weeks(3 months).The specific experimental design was as follows:24 db/db mice were randomly divided into four groups on average:negative control group(NC),aqueous extract of CS group(CS),aqueous extract of CS+moderate-intensity training group(CS+MT),and CS aqueous extract of CS+high-intensity training group(CS+HT).The maximum running speed,forelimb grip strength,body weight and fasting blood glucose of mice were measured before and after treatment.After the intervention,oral glucose tolerance test(OGTT)and insulin tolerance test(ITT)were conducted to assess glucose metabolism,while serum triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C)levels were measured to evaluate lipid metabolism.Results:After 3 months of intervention,there were significant differences in the maximum running speed and forelimb grip strength among the four groups(P＜0.05).The maximum running speed and forelimb grip strength of CS group,CS+MT group and CS+HT group were higher than those of NC group(P＜0.05).The CS+MT group exhibited higher forelimb grip strength,and the CS+HT group showed higher maximum running speed and forelimb grip strength compared to the CS group(P＜0.05),while no significant difference was found between the CS+MT and CS+HT groups(P＞0.05).Significant differences in body weight were observed among the four groups after 3 months of intervention(P＜0.05).Specifically,the CS+MT and CS+HT groups exhibited significantly lower body weight compared to both the NC and CS groups(P＜0.05),with the CS+MT group having the lowest body weight(P＜0.05).Fasting blood glucose levels also differed significantly among the groups after 2 and 3 months of intervention(P＜0.05).The CS,CS+MT,and CS+HT groups had lower fasting blood glucose levels compared to the NC group(P＜0.05),with the CS+MT and CS+HT groups showing the lowest levels(P＜0.05).No significant difference was found between the CS+MT and CS+HT groups(P＞0.05).After 3 months of intervention,significant differences in the area under the curve(AUC)of OGTT and ITT were observed among the four groups(P＜0.05).The AUC of OGTT and ITT were significantly lower in the CS,CS+MT,and CS+HT groups compared to the NC group(P＜0.05).The CS+MT and CS+HT groups exhibited the lowest AUC values for both OGTT and ITT(P＜0.05),with the CS+MT group showing the lowest AUC for OGTT(P＜0.05).Significant differences in serum lipid levels were observed among the four groups after 3 months of intervention(P＜0.05).TG,TC,and LDL-C levels were significantly lower,while HDL-C levels were higher in the CS,CS+MT,and CS+HT groups compared to the NC group(P＜0.05).The CS+MT group had the lowest TG levels and the highest HDL-C levels compared to the CS+HT group(P＜0.05),with no significant differences in TC and LDL-C levels between these two groups(P＞0.05).Conclusion:Aqueous extract of CS combined with different intensity training can significantly improve the exercise capacity and glycolipid metabolism of MS mice and reduce body weight,especially CS combined with MT treatment is more effective in improving lipid metabolism.In addition,when combined with HT,aqueous extract of CS can also play an auxiliary role in reducing the side effects of high-intensity exercise and improving the therapeutic effect.

The accumulation of uremic toxins such as urea nitrogen, blood creatinine, and uric acid of patients with renal failure in vivo would lead to aggravated kidney damage. In this study, coated aldehyde oxy-starch (CAO) was used as an adsorbent to investigate its in vitro adsorption performance on renal failure indexes for urea, indoxyl sulfate (INS), monomethylamine (MMA), dimethylamine (DMA), uric acid (UA), and creatinine (Cr). The effects of variables such as pH, temperature, concentration, dosage, and time on the adsorption capacity of CAO were systematically investigated, employing analytical techniques of high-performance liquid chromatography (HPLC) and gas chromatography (GC). The results revealed that CAO exhibited a strong adsorption capacity for urea, INS, and MMA, alongside a moderate adsorption capacity for DMA, UA, and Cr. The adsorption kinetics and thermodynamic studies indicated that the adsorption of urea and UA by CAO were fitted in pseudo-first-order kinetics, and the adsorption isotherm aligned with the Freundlich adsorption model. The enthalpy change ΔH of urea in adsorption was in the range of 40 to 60 kJ·mol^-1, which demonstrated the presence of strong adsorption force due to the interactions of coordinating groups. The ΔH of UA was greater than 80 kJ·mol^-1, indicating the generation of chemical bonds during the adsorption. Both of them, Gibbs free energy ΔG was less than 0, within the range of -20 to 0 kJ·mol^-1, suggested that the adsorption of urea and UA by CAO occurred spontaneously as physical adsorption process. The adsorption entropy ΔS of urea and UA was > 0, which indicated an increase in entropy throughout the adsorption. The infrared spectroscopygram showed the formation of a chemical bond, specifically the imine bond, following the adsorption of urea by CAO, thereby indicating a chemical reaction during the adsorption. This study elucidates the adsorption mechanism of CAO on various indexes of renal failure, providing a scientific basis for its clinical usage.

In recent years, robot-assisted esophagectomy has become increasingly widespread, but the esophagogastric anastomosis step remains relatively complex and cumbersome. Currently, commonly used gastrointestinal reconstruction anastomosis techniques include end-to-end anastomosis, end-to-side anastomosis, and side-to-side anastomosis. Depending on the anastomosis method, they can be further divided into manual anastomosis and mechanical anastomosis, with common instruments including circular staplers and linear staplers. In esophageal cancer surgery, the choice of esophagogastric anastomosis technique is typically based on the tumor’s location and size as well as the surgeon’s preference. Each anastomosis technique has its advantages and disadvantages. With continuous improvements in anastomosis techniques and updates in stapling instruments, the incidence of complications after esophagogastric anastomosis has been effectively reduced. However, safely and efficiently completing gastrointestinal reconstruction during surgery remains a significant challenge. Scholars have made extensive explorations in this field, actively proposing and achieving various reconstruction methods, leading to significant progress. This article reviews the research progress of robot-assisted esophagogastric anastomosis techniques from both the anastomosis techniques and methods perspectives.

Objective: To explore the relationship of physical activity (PA) and sedentary behavior (SB) with cardiorespiratory fitness (CRF) among middle schoold students in Tibet, so as to provide empirical references for improving the cardiorespiratory fitness and health levels of adolescents in Tibet. Methods: From August to December 2020, 1 225 junior and senior high school students were selected from 2 middle schools in Lhasa, Tibet Autonomous Region, using the stratified cluster random sampling method. Triaxial accelerometers were used to evaluate PA and SB behaviors, and the 20 meter shuttle run was employed to assess CRF among the middle school students. Isochronous substitution modeling was used to analyze the associations of SB, low intensity physical activity (LPA), and moderate vigorous physical activity (MVPA) with CRF, and the saturation threshold effect in the dose response relationship between MVPA and CRF was analyzed through restricted cubic spline and two stage linear regression. Results: After adjusting for covariates such as gender, body mass index and sleep quality score, isotemporal substitution analysis showed that among junior high school students aged 13-15, replacing 30 minutes of SB ( B =1.73) or LPA ( B =2.38) with MVPA were positively associated with CRF (both P <0.05). Among senior high school students aged 16-18, replacing SB ( B =0.99) or LPA ( B =1.38) with MVPA were also positively associated with CRF (both P <0.05). Restricted cubic spline and two piecewise linear regression analyses indicated that only middle school girls aged 13-18 exhibited a saturation threshold effect between MVPA and CRF (logarithmic likelihood ratio test=0.03), with the optimal CRF improvement observed at 60 minutes of MVPA per day ( B=0.13, P ＜ 0.01). Conclusions Reducing SB and LPA while increasing MVPA can improve CRF in Tibetan middle school students. To maximize CRF improvement, middle school girls should engage in at least 60 minutes of MVPA daily.
