Objective:Given the insufficiency of current clinical biomarkers for early diagnosis of esophageal adenocarcinoma(EAC),this study developed a panel of serum protein biomarker assays using liquid-phase chip technology and preliminarily validated the detection capabilities of these markers for EAC.Methods:Collected serum samples from 48 patients with EAC and 33 age-matched healthy controls(HC).The levels of squamous cell carcinoma antigen(SCCA),human cytokeratin 19 fragment(Cyfra21-1),hepatocyte growth factor(HGF)and IL-8 in serum were analyzed by liquid chip technology.The diagnostic efficacy of a single indicator and a combination of four indicators were evaluated by receiver operation characteristic(ROC)curve.Results:The detection ranges of SCCA,Cyfra21-1,HGF and IL-8 were 0.24～1 000 ng/ml,45.72～100 000 pg/ml,21.95～16 000 pg/ml,and 0.61～10 000 pg/ml,respectively.The liquid chip technology shows a strong correlation with clinical chemiluminescence immunoassay(r=0.949 4,P<0.000 1)and ELISA technology(r=0.955 1,P<0.000 1).Compared to the HC group,serum levels of SCCA and HGF were signifi-cantly elevated in the EAC group(P<0.01),IL-8 was significantly decreased(P<0.05),while Cyfra21-1 shows no significant difference(P>0.05).In the early EAC group,serum HGF was significantly higher than in the HC group(P<0.01).ROC curve analysis shows that among individual markers,HGF exhibits the best diagnostic efficacy for early EAC with an area under the curve(AUC)of 0.761,while the AUC for the combination of the four biomarkers was 0.857,both superior to the clinical biomarkers SCCA(AUC=0.604)and Cyfra21-1(AUC=0.515).Conclusion:Liquid chip technology is used to jointly detect SCCA,Cyfra21-1,HGF,and IL-8 in human serum.In the early diagnosis of EAC,the diagnostic efficacy of the combined use of these four biomarkers is superior to that of the commonly used clinical tumor markers SCCA and Cyfra21-1.This advantage stems from the high throughput and high sensitivity characteristics of liquid-phase chip technology.Consequently,this combined detection method holds significant clinical application and is expected to provide a more accurate and reliable tool for the early diagnosis of EAC.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

As one of traditional local treatments,photodynamic therapy(PDT)has mainly been used for the local eradicate and palliative treatment of malignant tumors.However,in recent years,more and more evidence has revealed a role of PDT in anti-tumor immunity,which attacked attention from researchers again.PDT can induce the immunogenic death of tumor cells as well as activation of both innate and adaptive immune systems,resulting in the enhancement of immune response against tumors.This article reviewed the advances regarding PDT and tumor immunity,aiming to systematically clarify the role of PDT in anti-tumor immunity and its potential applications in immunotherapy.

Objective:To investigate the risk factors of pleural effusion after spinal separation surgery for patients with spinal metastatic tumors.Methods:A total of 427 patients with spinal metastatic tumors from January 2014 to January 2022 in the Second Affiliated Hospital of Zhejiang University School of Medicine were retrospectively analyzed. There were 252 males and 175 females, with an average age of 59±12 years (range, 15-87 years). All patients underwent separation surgery. Based on the chest CT within 1 month after surgery, the volume of pleural effusion was measured individually by reconstruction software. Pleural effusion was defined as small volume (0-500 ml), moderate volume (500-1 000 ml), and large volume (above 1 000 ml). Baseline data and perioperative clinical outcomes were compared between the groups, and indicators with statistically significant differences were included in a binary logistic regression analysis to determine the independent risk factors for the development of pleural effusion after isolation of spinal metastatic cancer. Receiver operating characteristic (ROC) curves were conducted to calculate the area under the curve (AUC) for each independent risk factor.Results:All patients successfully completed the operation. Among the 427 patients, there were 35 cases of large pleural effusion, 42 cases of moderate pleural effusion, and 350 cases of small pleural effusion. There were significant differences in tumor size (χ 2=9.485, P=0.013), intraoperative blood loss ( Z=-2.503, P=0.011), blood transfusion ( Z=-2.983, P=0.003), preoperative total protein ( Z=2.681, P=0.007), preoperative albumin ( Z=1.720, P= 0.085), postoperative hemoglobin ( t=2.950, P=0.008), postoperative total protein ( Z=4.192, P<0.001), and postoperative albumin ( t=2.268, P=0.032) in the large pleural effusion group versus the small and moderate pleural effusion group. Logistic regression analysis showed that decreased preoperative albumin ( OR=0.89, P=0.045) and metastases located in the thoracic spine ( OR=4.01, P=0.039) were independent risk factors for the occurrence of large pleural effusion after separation surgery. The ROC curve showed that the AUC and 95% CI for preoperative albumin, lesion location, and the combined model were 0.637 (0.54, 0.74), 0.421 (0.36, 0.48), and 0.883 (0.81, 0.92). The combined predictive model showed good predictive value. Conclusion:The volume of pleural effusion can be measured individually and quantitatively based on chest CT. Decreased preoperative albumin and metastases located in the thoracic spine are independent risk factors for the occurrence of large pleural effusion after separation surgery. The combined prediction of the two factors has better predictive efficacy.

Objective To explore the related factors for the unilateral flap and bilateral flap by changing the origi-nal operation plan in the extraction of maxillary impacted mesiodens.Methods 81 patients with impacted mesio-dens in the middle of the maxillary were retrospectively analyzed.The primary outcome variables were planned sur-gery (unilateral flap) and unplanned surgery (bilateral flap) .The secondary outcome variables consisted of opera-tion time and postoperative swelling.The predictive variables were as follows:the differential value of the shortest distance from the supernumerary tooth to the labial and palatal bone plates, which was divided into≥1.5 mm group and<1.5 mm group; the ratio of the distance from the adjacent tooth apex to the nasal floor, compared to the length of the supernumerary teeth, was recorded as≥1 and< 1.A statistical software SPSS 20 was used to com-plete the statistical analysis.Results When the differential value was less than 1.5 mm, the possibility of un-planned surgery increased, and the probability of planned surgery was 0.085 times than that of unplanned surgery.With age growing each 1-year, the probability of planned surgery gradually decreased, HR=0.745.The postopera-tive swelling of the palatal approach was only 0.374 times than that of the labial approach.With age increasing, the operation time increased gradually, B=1.213.The ratio of the distance from the adjacent tooth apex to the na-sal floor to the length of the supernumerary teeth did not affect the change of the surgical plan during the operation.Conclusion The shortest distance difference between the supernumerary teeth and the labial and palatal bone plates can be used as a reference for the selection of surgical approach for the extraction of maxillary impacted me-siodens.

Objective:To investigate the effects of breast milk to total milk intake ratio during hospitalization on the duration of antibiotic therapy in preterm infants less than 34 weeks of gestation.Methods:Clinical data of preterm infants ( n=1 792) less than 34 gestational weeks were retrospectively collected in 16 hospitals of Jiangsu Province Neonatal-Perinatal Cooperation Network from January 1, 2019, to December 31, 2021. The days of therapy (DOT) were used to evaluate the duration of antibiotic administration. The median DOT was 15.0 d (7.0-27.0 d). The patients were divided into four groups based on the quartiles of DOT: Q 1 (DOT≤7.0 d), Q 2 (7.0 d27.0 d) groups. According to the breast milk intake ratio (breast milk intake to total milk intake during hospitalization×100%), they were also divided into four groups: very-low-ratio breastfeeding group (breast milk intake ratio≤25%), low-ratio breastfeeding group (25%75%). Univariate analysis ( Chi-square test and Kruskal-Wallis rank-sum test) was used to analyze the factors influencing DOT. Spearman correlation analysis and trend Chi-square test were used to explore the relationship between breast milk intake ratio and DOT. After using multiple imputations to address missing data, two models were constructed after adjusting for different factors, and multinomial logistic regression model was applied to evaluate the effects of the breast milk intake ratio on DOT. Finally, sensitivity analysis was conducted to assess the stability of the models. Results:(1) Of the 1 792 preterm infants, there were 507 (28.3%) in the Q 1 group, 422 (23.5%) in the Q 2 group, 438 (24.4%) in the Q 3 group and 425 (23.7%) in the Q 4 group. (2) The median values of DOT in the very-low-ratio, low-ratio, medium-ratio and high-ratio breastfeeding groups were 20.0 d (11.0-31.0 d), 20.0 d (11.0-32.0 d), 13.0 d (6.0-25.8 d) and 10.0 d (4.0-21.0 d), respectively. Compared with the very-low-ratio and low-ratio breastfeeding groups, the medium-ratio and high-ratio breastfeeding groups had shorter DOT (all P<0.05). (3) After adjusting for factors with P<0.1 (prenatal glucocorticoid exposure, antimicrobial use within 24 h before delivery, gestational age at delivery, birth weight, Apgar score≤7 at 1 min, neonatal respiratory distress syndrome, infectious pneumonia and early-onset neonatal sepsis) between the DOT quartile groups, it showed that medium-ratio and high-ratio breastfeeding were protective factors in contrast to very-low-ratio breastfeeding in the Q 2, Q 3 and Q 4 groups as compared with the Q 1 group [Q 2 group: OR=0.50 (95% CI: 0.30-0.85) and OR=0.36 (95% CI: 0.26-0.51); Q 3 group: OR=0.31 (95% CI: 0.18-0.55) and OR=0.20 (95% CI: 0.14-0.29); Q 4 group: OR=0.22 (95% CI: 0.12-0.42) and OR=0.17 (95% CI: 0.12-0.26)]. Conclusion:Breast milk intake accounting for over 50% of total milk intake has a positive impact on reducing DOT in premature infants requiring antibiotics, which suggests that breastfeeding should be actively encouraged.
