Objective: To explore whether digital facial and tongue diagnostic technologies can support the assessment of coronary heart disease (CHD) patients for coronary artery stenosis severity, and examine potential associations between digital tongue diagnosis features and myocardial biomarkers. Methods: The TFDA-1 face and tongue diagnosis instrument and the TDAS analysis system were used to perform intelligent visual examination and analysis of the facial and tongue in CHD patients who attended the Department of Cardiology at Shanghai Baoshan Hospital of Integrated Traditional Chinese and Western Medicine between October 2, 2023 and July 31, 2024. Variables were screened using principal component analysis (PCA) and multicollinearity analysis to construct four machine learning models, including random forest, LightGBM, decision tree, and naive Bayes, for the early prediction of coronary artery stenosis severity. Model performance metrics, including sensitivity, specificity, precision, F1 score, accuracy, and the area under the receiver operating characteristic (ROC) curve (AUC), were evaluated. Visual analyses were performed using the SHapley Additive exPlanations (SHAP) interpreter and decision curve analysis. For patients after percutaneous coronary intervention (PCI), a conceptual model linking cardiac biomarkers and tongue diagnosis was constructed using the partial least squares structural equation modeling (PLS-SEM), and its validity was assessed. Results: A total of 459 CHD patients were enrolled and assigned to a PCI group and a non-PCI group (which comprised two subgroups: mild stenosis or less group, moderate stenosis or greater group). For sublingual vein (SV) features, the PCI group had lower SV-a and SV-b than the other groups (P < 0.01 and P < 0.05, respectively). For tongue surface features, the PCI group had significantly higher tongue body (TB)-L, TB-a, and TB-b (P < 0.05, P < 0.01, and P < 0.001, respectively), as well as higher tongue coating (TC)-a and TC-b (P < 0.01 and P < 0.001, respectively). Age, SV-a, SV-b, creatine kinase-myocardial band (CK-MB), CK, TC-a, lip-L, and lip-b were incorporated in the machine learning models. The random forest model performed best, with an AUC of 0.924, an F1 score of 0.839, precision of 0.807, accuracy of 0.864, sensitivity of 0.873, and specificity of 0.839. Decision curve analysis indicated that both LightGBM and random forest had clinical utility. PLS-SEM confirmed the pathway relationships: myocardial biomarkers → TB and myocardial biomarkers → TC (coefficient = – 0.238, t = 2.239, P = 0.025, and coefficient = – 0.270, t = 2.522, P = 0.012, respectively). Conclusion This study developed a noninvasive early warning model for coronary artery stenosis in patients with CHD. It applied PLS-SEM to investigate the association between post-PCI cardiac biomarkers and tongue diagnosis, and validated the proposed association chain. These findings suggest that intelligent traditional Chinese medicine (TCM) visual diagnosis integrated with modern digital technology may support CHD risk assessment and comprehensive health management.

To investigate the effect of isthmin-1 (ISM1) on the invasion and metastasis of pancreatic cancer and its underlying mechanism, this study analyzed the expression of ISM1 in pancreatic cancer patients and normal pancreatic tissues using The Cancer Genome Atlas (TCGA) database. Western blot was employed to detect differences in ISM1 protein expression between pancreatic cancer cell lines (Aspc1, Bxpc3, PANC1, SW1990) and the pancreatic epithelial cell line (hPNE). Cell models with stable ISM1 overexpression and knockdown were constructed, and changes in cell migration and invasion capabilities were assessed via Transwell invasion assays and wound healing assays. Meanwhile, Western blot was used to detect the expression levels of key markers of epithelial-mesenchymal transition (EMT). Furthermore, TCGA and the Gene Expression Omnibus (GEO) database were utilized to analyze pathways regulated downstream of ISM1 and the mechanisms promoting pancreatic cancer invasion and metastasis. Immunoprecipitation combined with mass spectrometry (IP-MS) was used to screen for vimentin as an ISM1-binding protein, and the interaction between ISM1 and vimentin was verified by immunofluorescence and co-immunoprecipitation (Co-IP). Bxpc3 cells overexpressing ISM1 were treated with the protein synthesis inhibitor cycloheximide (CHX) to detect vimentin protein stability. The results indicate that ISM1 promotes the EMT process by inhibiting vimentin degradation, thereby enhancing the invasion and metastasis of pancreatic cancer. This study provides new experimental evidence for elucidating the mechanism of pancreatic cancer metastasis.

Objective:To evaluate the effect of esketamine on the quality of postoperative sleep in preschool children undergoing day surgery.Methods:This was a prospective randomized controlled study. One hundred and four preschool children of either sex, aged 4-7 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, underwent elective day surgery for strabismus correction under general anesthesia at the First Affiliated Hospital of Zhengzhou University from July to September 2024, were selected. The preschool children were divided into 2 groups ( n=52 each) by the random number table method: control group (group C) and esketamine group (group S). In group S, additional esketamine 0.25 mg/kg was intravenously injected during anesthesia induction. The sleep quality scores were evaluated using the Children′s Sleep Habit Questionnaire by the guardians on the night before surgery, the 1st night after surgery, the 3rd night after surgery and the 7th night after surgery, and development of postoperative sleep disorders (the Children′s Sleep Habit Questionnaire score >41) was recorded. The FLACC pain scores and usage rate of flurbiprofen axetil were recorded immediately before leaving the postanesthesia care unit (PACU) and on days 1, 3 and 7 after surgery. The time of laryngeal mask airway removal, length of stay in PACU and development of adverse reactions such as increased oral secretions, agitation, nausea and delirium within 48 h after surgery were recorded. Results:Compared with group C, the Children′s Sleep Habits Questionnaire score and incidence of postopoerative sleep disorders were significantly decreased on the 1st night after surgery, the FLACC pain scores were decreased immediately before discharge from the PACU and at 1 day after surgery, the usage rate of flurbiprofen axetil was decreased ( P<0.05), and no significant change was found in the time of laryngeal mask airway removal, length of stay in PACU and incidence of postoperative adverse reactions in group S ( P>0.05). Conclusions:Anesthesia induction with esketamine 0.25 mg/kg can improve the quality of postoperative sleep in preschool children undergoing day surgery.

Objective:To investigate the status and diagnostic reference levels (DRLs) of adult CT radiation dose based on survey result from some hospitals in Beijing.Methods:From September to December 2023, the survey results for 50 hospitals were collected in Beijing, including 47 tertiary hospitals and 3 second grade general hospitals. The CT data sets in total of 20 items including head (sequential scanning), head (spiral scanning), head perfusion, sinus, neck, chest, chest (low dose scanning), abdomen, pelvis, abdomen-pelvis, chest-abdomen-pelvis, lumbar spine, CT urography, coronary CTA (retrospective), coronary CTA (prospective), head CTA, neck CTA, aorta CTA, leg CTA and knee were collected on clinical commonly used CT scanners with annual qualified state inspection. For each item, radiation dose data was collected continuously and randomly for up to 50 cases for every CT scanner. Using the volume CT dose index (CTDI vol) and dose length product (DLP) as dose parameters, the median value of each item in each hospital was obtained. The median CTDI vol and DLP values of all hospitals were arranged, and the local DRL of each item was set as the 75th percentile of the median values. The obtained DRLs were compared with the DRLs issued by domestic and international radiological protection organizations. Results:A total of 26 031 dose values of adult patients were collected and 25 996 dose values were left while 35 invalid values removed.For different CT users, CTDl vol, DLP and scanning phases were different for the same item. The five items with the highest CTDI were head perfusion, head sequential scanning, head spiral scanning, coronary CTA (retrospective mode), and sinus. The five items with the highest DLP were CTU, head perfusion, leg CTA, chest-abdomen-pelvis and aortic CTA. The CTDI vol of CTU was only 16.9 mGy (75th percentile), while the DLP was as high as 2 394.9 mGy·cm (75th percentile). The survey showed that the DRLs of most items in Beijing was lower than the national DRLs of domestic and foreign standards, and the DRLs of a small number of items were slightly higher. Conclusion:The current CT dose level in Beijing is not consistent with national DRLs released at home and abroad, so it is necessary to establish local DRLs according to the clinical status in Beijing.

Objective:To investigate devices for radiodiagnosis used in medical institutions in Beijing, China, as well as radiation workers and the devices′ application frequencies, in order to provide data support for determining radiation protection measures and allocating resources for clinical radiodiagnosis.Methods:In October 2023, questionnaires were distributed to the members of the Radiation Technology Branch of the Beijing Medical Association who work in medical institutions at different levels across varying districts of Beijing. The collected data included information about devices for radiodiagnosis and radiation workers, as well as the application frequencies of various medical X-ray imaging devices during 2018-2022, in 38 medical institutions of Level 3 Grade A, Level 3, and Level 2 in 14 municipal districts of Beijing. Then, the collected data were organized using the Microsoft Power BI software to form report models, followed by the statistical analysis of data on the devices, radiation workers, and application frequencies were using the RStudio software.Results:The 38 medical institutions in Beijing possess 591 devices for radiodiagnosis and 2 018 staff in the departments of radiology, including 1 037 radiologic technologists and 738 physicians, with 1.77 technologists and 1.26 physicians arranged for a single device on average. From 2018 to 2022, among all examinations of radiodiagnosis, computed tomography (CT) scans showed the highest frequencies, with total and average annual growth rates of 138.06% and 108.40%, respectively. Specifically, chest CT scans exhibited total and average annual growth rates of 225.20% and 122.50%, respectively. X-ray imaging ranked second in application frequency, with total average annual growth rates of 70.20% and 91.53%, respectively. Notably, chest X-ray imaging showed total and average annual growth rates of 63.89% and 89.41%, respectively.Conclusions:From 2018 to 2022, X-ray imaging examinations displayed significantly fluctuating frequencies with an overall decline trend in the 38 medical institutions. In contrast, the CT scans showed increased frequencies, with chest CT scans displaying an increased frequency and proportion. This necessitates ensuring the justification of CT scans.

Objective:To investigate the efficacy and safety of transurethral incision for the treatment of ureterocele in infants.Methods:A retrospective analysis of 28 cases of ureterocele admitted from March 2012 to May 2023 were reviewed, all of which were less than 1 year old, 16 male and 12 female, with an average age of(5.7±3.5)months. The ureterocele was located on the left side in 8 cases, on the right side in 15 cases, and bilaterally in 5 cases. There were 12 cases of single system ureterocele, of which 7 cases were unilateral and 5 cases were bilateral. Duplex system ureterocele was observed in 16 cases, all of which were unilateral. Clinical manifestations: urinary tract infection in 13 cases, 11 cases of ureterocele or hydronephrosis and ureteral dilation were found during antenatal examination, and 4 cases of ureterocele were found after birth. Urological ultrasound, intravenous pyelography(IVP) and voiding cystourethrography(VCUG) were performed in all children, and 17 cases underwent magnetic resonance urolography (MRU), and confirm the diagnosis of ureterocele preoperatively. All of the cases were performed the transurethral incision.The ureterocele was punctured and incised 1-2 mm at the base of the bulge, and 2-4 points were punctured according to the bulge atrophy. Bilateral ureteroceles were punctured and incised simultaneously. Postoperative urine routine test, urinary tract color ultrasound and VCUG were performed to determine if there is urinary tract infection, hydronephrosis, ureteral dilation and bulging, and whether a second surgery is needed.Results:All operations were conducted successfully. The intraoperative bleeding was less than 3 ml and no intraoperative complications. The operative time was (28.4±10.3) min. The median postoperative follow-up was 34 (32, 36) months. Six cases underwent postoperative VCUG examination. Eleven children were recovered well with single systemic ureterocele. One child developed grade Ⅳ vesicoureteral reflux(VUR)and combined with bladder diverticulum, and ureterocele underwent open diverticulotomy and ureteral reimplantation six months after surgery. Nine children were recovered well with duplex systemic ureterocele. Six cases of children developed infection, of which 2 cases had an infection once within one month after TUI, and the other four cases still had intermittent infections after six months and VCUG was performed, and one case showed grade Ⅲ VUR of the lower ureter, which was observed conservatively, while the other three cases had enlarged cysts but no VUR, and upper heminephrectomy was performed, and the patients recovered well after surgery. Except for these 6 exceptions, in another case, after ten years of follow-up, the ureterocele became larger but no VUR, and the results were good after a second transurethral incision. There was no significant difference in the postoperative infections, new VUR cases, and secondary surgeries between the two groups.Conclusions:Transurethral incision has good surgical effect on children with single system ureterocele and duplex system ureterocele, and has advantages of easy operation, less trauma, safety and effectiveness, and few complications. It deserves to be recommended as the treatment of choice, especially for infants and young children.

Objective:To investigate the efficacy and safety of darolutamide in the treatment of patients with metastatic hormone-sensitive prostate cancer.Methods:A retrospective analysis was conducted on 17 cases of prostate cancer patients who received treatment with darolutamide in combination with ADT at our hospital from January to December 2022. The median age was 70 (range: 56 to 92) years old. The median pre-treatment prostate-specific antigen (PSA) level was 63.50 (range: 29.16 to 700.74) ng/ml. Sixteen cases had a Gleason score of 8 or above, and 11 cases were classified as high tumor burden (with four or more bone metastases and/or visceral metastases). The patients were treated with darolutamide in combination with goserelin (10.8 mg, subcutaneous injection, every 12 weeks). The decrease in PSA levels was observed at 2 weeks and at 1, 2, 3, and 6 months post-treatment. The time to achieve a 50% decrease in PSA level (PSA50), a 90% decrease (PSA90), and a PSA level of ≤0.2 ng/ml was recorded.Adverse drug reactions were also documented.Results:All the 17 patients were followed up and continued to receive darolutamide at our center without any loss to follow-up. The median follow-up time was 11.4(8.9, 15.3)months. It showed a median PSA decrease from baseline of 83.33% at 2 weeks, 95.37% at 1 month, 96.71% at 2 months, 97.22% at 3 months, and 99.10% at 6 months. The median time to achieve PSA50, PSA90, and PSA ≤ 0.2 ng/ml were 1.3 (0.9, 1.7)months, 1.7 (1.2, 2.4)months, and 3.6 (2.9, 4.5)months respectively. Six patients with bone metastases experienced relief of metastatic lesions after treatment. Only one patient developed papules on the left upper limb, which were assessed as grade 1 rash, and the rash disappeared after three days treatment of topical application of hydrocortisone cream.Conclusions:Darolutamide could rapidly control and significantly reduce PSA levels in prostate cancer patients, with a favorable safety profile.

Objective:To understand spatial aggregation of lung cancer mortality and its changing trends over the past fifty years in different counties and districts of Shandong Province from 1970 to 2021.Methods:The mortality data of lung cancer were obtained from the death registration system of Shandong province and three retrospective surveys of death cause. The mortality rate and age-standardized mortality rate were used to describe the changing trend of lung cancer in different years, and the contribution value of population factors and non-population factors in lung cancer mortality change was calculated by the mortality differential decomposition method. GeoDa 1.20 and ArcGIS 10.8 software were used for spatial autocorrelation analysis and visualization map display.Results:The crude mortality rate of lung cancer in Shandong Province showed a significant upward trend from 1970 to 2021, rising from 7.22 per 100 000 in 1970-1974 to 62.73 per 100 000 in 2020-2021, with an increase of 7.69 times. Meanwhile, the standardized mortality rate of lung cancer exhibited a trend of increasing first and then decreasing. The differential analysis of lung cancer mortality in different years revealed that changes in crude mortality rates were the result of the combined effects of demographic and non-demographic factors. The proportion of population factors (aging population) leading to an increase in lung cancer mortality rate rose from 2.12% in 1990-1992 to 40.20% in 2020-2021. From a spatial distribution perspective, there were significant regional differences in lung cancer mortality rates among counties (cities, districts) in Shandong Province across different eras. Compared to the period of 1970-1974, the lung cancer mortality rates in all counties and districts in 2020-2021 showed a considerable increase, and there were noticeable changes in the areas of high-high and low-low clustering of lung cancer mortality rates across different eras.Conclusion:There have been significant temporal and spatial changes in the mortality rate of lung cancer in Shandong Province from 1970 to 2021. The crude mortality rate has shown an upward trend, while the standardized mortality rate increases first and then decreases. The concentration of lung cancer mortality rates in counties and districts has also undergone significant changes.

Objective:To evaluate the clinical efficacy of infraorbital rim drilling midface lift combined with composite lower blepharoplasty.Methods:Retrospective analysis of clinical data from the patients who underwent combined midface lift and lower blepharoplasty at Department of Medical Cosmetic Center, Affiliated Hangzhou First People’s Hospital, Westlake University School of Medical, between January 2022 and February 2024.The infraorbital rim drilling midface lift combined with lower blepharoplasty was performed via a subciliary incision approach. Through a subciliary incision, the herniated orbital fat was excised, followed by fixation of the orbital septum to the infraorbital rim periosteum. Drill holes were created at the medial and lateral infraorbital rim, and arcuate suspension of the midface was performed using 2-0 absorbable sutures (SXPP1A405). Postoperative follow-up assessed midface lifting outcomes and complication rates. The wrinkle severity rating scale (WSRS) was used to grade nasolabial folds pre- and postoperatively (5-point scale: higher scores indicating more pronounced folds). Patient-reported outcomes were assessed using the Face-Q questionnaire, evaluating: (1) overall facial satisfaction, (2) satisfaction with surgical results, and (3) satisfaction with decision (scale 0-100; higher scores indicating greater satisfaction/less decisional regret). Descriptive statistical methods were employed for data analysis.Results:A total of 43 patients were enrolled, comprising 7 males and 36 females, with a mean age of (50.6±12.2) years (range: 32-73 years). Postoperative follow-up averaged (11.9±4.6)months. All patients demonstrated significant improvement in lower eyelid bags, tear trough deformity, midface elevation, and nasolabial folds. Surgical complications included: residual lower eyelid fat ( n=5), intermittent fixation point pain persisting >1 month ( n=4), mild residual tear trough deformity ( n=4), and hematoma ( n=1). Nasolabial fold WSRS scores decreased from ( 3.7±0.9 ) points to(2.9±0.6)points following surgery. In 38 patients, Face-Q scores demonstrated high satisfaction levels: appearance-related satisfaction scored (80.9 ± 10.3)points and satisfaction with decision scored (82.4 ± 8.9)points, indicating favorable patient-reported outcomes. Conclusion:The infraorbital rim drilling-assisted midface lift combined with comprehensive lower blepharoplasty effectively corrects midface ptosis while addressing lower eyelid bags. This technique provides reliable fixation points through drilling, resulting in stable and long-lasting lifting outcomes with high patient satisfaction.
