Objective:To investigate the incidence of venous thromboembolism (VTE) in patients with esophageal cancer (EC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 8 458 EC patients who were admitted to Sichuan Cancer Hospital from January 2017 to December 2021 were collected. There were 6 923 males and 1 535 females, aged (64±9)years. There were 3 187 patients undergoing surgical treatment, and 5 271 cases undergoing non-surgical treatment. Observation indicators: (1) incidence of VTE in EC patients; (2) treatment and outcomes of patients with VTE. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the nonparameter rank sum test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the nonparameter rank sum test. Results:(1) Incidence of VTE in EC patients. Of 8 458 EC patients, 175 cases developed VTE, with an incidence rate of 2.069%(175/8 458). Among 175 VTE patients, there were 164 cases of deep venous thrombosis (DVT), 4 cases of pulmonary embolism (PE), 7 cases of DVT and PE. There were 59 surgical patients and 116 non-surgical patients. There was no significant difference in thrombus type between surgical and non-surgical EC patients with VTE ( χ2=1.95, P>0.05). Of 3 187 surgical patients, the incidence of VTE was 1.851%(59/3 187), including an incidence of 0.157%(5/3 187) of PE. PE accounted for 8.475%(5/59) of surgical patients with VTE. Of 5 271 non-surgical patients, the incidence of VTE was 2.201%(116/5 271), including an incidence of 0.114%(6/5 271) of PE. PE accounted for 5.172%(6/116) of non-surgical patients with VTE. There was no significant difference in the incidence of VTE or PE between surgical patients and non-surgical patients ( χ2=1.20, 0.05, P>0.05). (2) Treatment and outcomes of patients with VTE. Among 175 EC patients with VTE, 163 cases underwent drug treatment, and 12 cases did not receive treatment. Among 163 cases with drug therapy, 158 cases underwent anticoagulant therapy, 5 cases were treated with thrombolysis. All the 163 patients were improved and discharged from hospital. Conclusions:The incidence of VTE in patients with EC is relatively low, as 2.069%. There is no significant difference in the incidence of VTE or thrombus type between surgical EC patients and non-surgical EC patients.

Objective:To investigate the effects of methyltransferases like 3(METTL3)mediated m6A modification of double homology cassette A pseudogene8(DUXAP8)on the proliferation,migration and invasion of salivary adenoid cystic carcinoma SACC-LM cells and its potential molecular mechanisms.Methods:Whole-transcriptome sequencing showed that DUXAP8 was highly ex-pressed in SACC than in para-cancerous tissues(P＜0.05).The m6A modification sites on DUXAP8 were predicted using the SRAMP website,and the mRNA and protein expression of m6A-modified genes and the genes associated with the epithelial-mesen-chymal transition(EMT)was measured by qRT-PCR and Western blot,respectively.METTL3 and DUXAP8 was knocked down or overexpressed in SACC-LM cells,and the proliferation,migration,and invasion of the cells were assessed by CCK-8,scratch and Transwell assays.The correlation between METTL3 and DUXAP8 was evaluated using MeRIP-qPCR.Results:The expression of DUXAP8 in SACC tumor was higher than that in para-cancerous tissues(P＜0.05).Knockdown of DUXAP8 reduced proliferation,migration and invasion of SACC-LM cells,as well as the expression of EMT-related genes(P＜0.05).Multiple m6A modification sites of high confidence were found on DUXAP8.METTL3 was highly expressed in tumor tissues,more than other related genes(P＜0.05)and enzyme-encoding genes in SACC-LM cells(P＜0.05).METTL3 was found to function as a methyltransferase to regulate the expression of DUX-AP8,and downregulation of METTL3 inhibited prolifera-tion,migration and invasion of SACC-LM cells and partially reversed the promotion of these activities induced by DUX-AP8 overexpression(P＜0.05).Conclusion:METTL3-me-diated m6A modification upregulated DUXAP8 expression,which promotes the proliferation,migration and invasion of SACC cells.

Objective This study aims to obtain a three-dimensional reconstruction model based on magnetic reso-nance imaging(MRI)data of patients with different degrees of unilateral cleft lip and analyze the anatomy and changes in multiple groups of nasolabial muscles under dynamic and static conditions.Methods One normal person and four adult patients with unilateral cleft lip were included,and MRI was performed under static(upper and lower lips closed naturally)and dynamic(pout and grin)conditions.3D Slicer software was used to reconstruct the model and draw the anatomic morphology of nasolabial muscles.The distance between the junction(where the muscle merges into the orbicularis oris)of the levator muscle,zy-gomaticminor muscle,and zygomatic major muscle to the median sagittal plane,the starting point to the junction point,the dynamic and static junction points,and the angle between the connection of dynamic and static junctions and the hori-zontal plane were measured under three kinds of movements,and the ratio was calculated.Results In all patients,un-der dynamic and static conditions,the distance from the muscle junction to the median sagittal plane,their ratios of the cleft side to the non-cleft side were all greater than 1.While the ratios of the distance from the starting point of the mus-cle to the junction point were less than 1.At static conditions,the two ratios of the same muscle increased gradiently with the severity of the cleft,and the ratio of the zygomatic minor muscle was prominent in the same patient.The ratio of the cleft side to the non-cleft side was greater than 1,and the value for comparison was the angle of the line from the static to the dynamic junction and the horizontal plane.Conclusion The symmetry of the insertion site of the orbicularis oris and the linear distance of both sides of the muscle are related to muscle and cleft types.The angle of muscle contraction on the cleft side is greater than that on the non-cleft side.

Objective This study aimed to compare the impacts of undertaking symmetrical bone repair of the nasal alar base combined with nasolabial deformity repair versus nasolabial deformity repair alone on the improvement in nasal de-formity of patients with unilateral cleft lip and alveolar cleft.Methods Fifty patients presenting with unilateral cleft lip and alveolar cleft were evaluated.Among them,20 underwent nasolabial deformity repair solely(non-bone grafting group),whereas 30 patients received bone repair in conjunction with nasolabial deformity repair(bone-repair group).Preoperative measurements and one-year follow-up results were assessed through photographic anthropometric analysis.According to the Farkas anthropometric standard,the nasal anatomic landmarks were located,and 10 nostril indicators were measured.The operative effects of two groups were compared.Results In contrast to the non-bone-grafting group,the nasal deformity of patients in the bone-repair group demonstrated significant improvement one year post-operation.The symmetry pa-rameters of the nasal columella more closely approximated 1,the columella deviation angle more closely approached 90°,and the sub-alare inclination angle and the inclination angle of the nasal alar were smaller(P＜0.05).Conclusion The accomplishment of symmetrical bone repair of the nasal alar base is conducive to enhancing nasal deformity after cleft-lip surgery in patients with unilateral cleft lip and alveolar cleft.This strategy has a positive influence on nasal symmetry,the morphology of the nasal alar,and nasal base deformity.

Objective:To explore the relationship between atherosclerotic index of plasma(AIP)and vulnerable plaque of coronary under computed tomography(CT)based on coronary CT angiography(CCTA).Methods:Data were retrospectively collected on 213 patients with coronary heart disease(CHD)who underwent CCTA examination from January 2021 to February 2024 at the Second Affiliated Hospital of Shenyang Medical College,and they were divided into a vulnerable plaque group(123 cases)and a non-vulnerable plaque group(90 cases)according to whether existed vulnerable plaque of coronary artery.General clinical data such as age,gender,history of smoking,history of alcohol consumption,history of diabetes,and serum indicators such as AIP were collected.The differences in AIP and other factors between the two groups were compared.The independent influencing factors of vulnerable plaque of coronary artery were determined by multifactorial logistic regression analysis,and the predictive value of AIP for vulnerable plaque was assessed by drawing a receiver operating characteristic(ROC)curve.Results:AIP of vulnerable plaque group was 0.22±0.31,which was higher than that 0.05±0.27 of the vulnerable plaque group,and the difference of AIP between two groups was significant(t=4.223,P<0.001).Multifactorial logistic analysis showed there was independent correlation between AIP and vulnerable plaque under CT(OR=7.556,95%CI:2.442～23.385,P=0.002).The ROC curve showed that the best cut-off value of AIP was 0.20 in predicting vulnerable plaque under CT,and the value of area under curve(AUC)was 0.665,and the sensitivity was 55.56%and the specificity was 73.98%.Conclusion:AIP is an independent influencing factor for CHD patients who complicate vulnerable plaques,and it has a certain of predictive value for vulnerable plaques.

OBJECTIVES: This study aimed to explore the relationship between alveolar cleft and secondary nasal deformity post unilateral cleft lip repair in adults. METHODS: A total of 27 patients aged 16-30 years old with unilateral secondary nasal deformity and alveolar cleft were included, 13 of whom underwent bone grafting. Spiral CT data of all preoperative and postoperative patients who had alveolar bone grafting were collected. Then, Mimics software was used for three-dimensional reconstruction to evaluate the correlation between the width, height, and volume of the alveolar cleft and those of the nasal deformity. The difference in nasal deformity before and after alveolar bone grafting was also explored. RESULTS: The width of the alveolar cleft was positively correlated with the difference in bilateral nostril floor width (P<0.05). As the effective depth of the alveolar cleft increased, the sub-alare inclination angle largened (P<0.05). However, no significant difference was found in the nasal deformity between before and after alveolar bone grafting. CONCLUSIONS Alveolar cleft is closely related to secondary nasal deformities post unilateral cleft lip repair, especially nasal floor deformities. Alveolar bone grafting benefits adult patients for the improvement of secondary nasal deformities post unilateral cleft lip repair.

OBJECTIVES: The long-term effect of muscular force balance reconstruction technique combined with intranasal fixation for correcting secondary nasolabial deformity after unilateral cleft lip was evaluated. The aim was to provide a basis for further improving the surgical treatment effect of secondary nasolabial deformity of acleft lip. METHODS: A total of 40 patients aged 4-28 years with secondary nasal deformity and unilateral cleft lip were selected as research subjects. The two-dimensional photo measurement analysis method was used in comparing the surgical results before and immediately after the operation (7 d) and 1 year after the operation. RESULTS: Columellar angle, nostril height ratio (NHR), alar rim angle, alar rim angle ratio, and nostril shape (NS) increased dimmediately after the operation, whereas alar base width ratio (ABWR) and nostril width ratio decreased (NHR) immediately after the operation (P<0.01). The ABWR, NHR, and NS immediately after the operation were not significantly different from those 1 year after the operation (P>0.05). CONCLUSIONS Muscular force balance reconstruction technique combined with intranasal fixation is effective in the repair of unilateral secondary nasolabial deformity, and stable results can be obtained 1 year after surgery.

Objective:To investigate the risk factors affecting the delay of recovery in patients under general anesthesia.Methods:Patients who underwent radical mastectomy for breast cancer in our hospital from Jul. 2020 to Aug. 2022 were selected as the research objects, and the effective data of 80 patients were obtained after screening. The patients were divided into the non-delayed recovery group (54 cases) and the delayed recovery group (26 cases). The general conditions and perioperative data of the two groups were compared, and the high-risk factors affecting delayed recovery from anesthesia were analyzed using the Logistic hazard proportional regression model. Results:In general, there were no significant differences in body mass index, hypertension, diabetes, tumor size, tumor subtype, tumor location, or tumor stage between the non-delayed awakening group and the delayed awakening group (all P>0.05). The average age of patients in the wake-up delay group was (53.28±11.01), the proportion of anemia was 42.30% (11/26), and the proportion of ASA Ⅱ patients was 76.92% (20/26) compared with the average age of the non-wake-up delay group (46.89±6.91) ( t=3.17, P=0.002), the proportion of anemia was 20.37% (11/54) ( χ2=3.17, P=0.040), the proportion of ASA Ⅱ patients was 27.78% (15/54) ( χ2=17.22, P<0.001), which was significantly increased. In the perioperative data, there was no statistical significance in the intraoperative combined epidural anesthesia between the non-delayed recovery group and the delayed recovery group (all P>0.05). The data of the patients in the delayed recovery group, including average intraoperative blood loss (234.14±32.28), operation time (229.47±29.84), anesthesia time (246.14±35.64) and intraoperative compound sevoflurane inhalation accounted for 69.23% (18/26) ,which were significantly increased compared with the data of non-delayed recovery group following, including the average intraoperative blood loss (215.48±29.54) ( t=2.57, P=0.012), operation time (206.35±27.41) ( t=3.43, P=0.001), anesthesia time (215.61±28.54) ( t=4.13, P<0.001), intraoperative compound sevoflurane inhalation (44.44%, 24/54). Through Logistic hazard ratio regression analysis, it was found that age ( OR=1.15, 95% CI: 1.05-1.30, P=0.008), ASA Ⅱ grade ( OR=9.49, 95% CI: 2.05-60.94, P=0.008), intraoperative bleeding volume ( OR=1.04, 95% CI: 1.01-1.08, P=0.012), operation time ( OR=1.05, 95% CI: 1.01-1.08, P=0.009), and anesthesia time ( OR=1.04, 95% CI: 1.02-1.07, P=0.004) were high-risk factors affecting the delayed recovery from anesthesia. Conclusion:Increasing age, high grade of ASA, heavy intraoperative blood loss, long operation time and anesthesia time are independent risk factors affecting delayed recovery from anesthesia.

Alveolar cleft is one of the key links of cleft lip and palate reconstruction due to its close relationship with tooth and jaw coordination and nasolabial deformity. The alveolar bone graft repairs the hole in the gum ridge and stabilizes the bone arch, providing better support for the base of the nose and new bone for the roots of the developing teeth to grow into. Unfortunately, bone graft failure in the traditional way, even among minor clefts, bony hypoplasia, or absence that affects the nasal base and piriform rim, is common. Two-stage alveolar bone grafting, which has advantages in addressing the underlying skeleton and deficiency, could be an optional surgical procedure for nasal floor reconstruction in adult patients with a broad alveolar cleft.
