ABSTRACT
Objective: To evaluate the function of serum dehydroepiandrosterone sulfate (DHEAS) in adult adrenal space-occupying lesions. Methods: In this cross-sectional study, 395 patients with adrenal space-occupying lesions who had their DHEAS levels measured were collected from the First Medical Center of Chinese PLA General Hospital from January 2010 to June 2021. They were divided into the adrenal Cushing syndrome (ACS) group (n=100) and non-ACS group (n=295). The former was divided into the cortisol-producing adrenal adenoma (CPA) group (n=67) and primary bilateral macronodular adrenal hyperplasia (PBMAH) group (n=33). Clinical data of each group were collected and compared among groups by independent samples t-test, chi-square test, and Mann-Whitney U test. Serum DHEAS ratio corrected for age and sex was further constructed to identify the receiver operating characteristic curve and the optimal tangent point value for different adrenal occupation. Results: Patients in the ACS group were younger (44.9±13.7 vs. 49.9±12.5, P=0.001); had a larger proportion of women (79/100 vs.139/295, P=0.001); and had higher cortisol levels [8â¶00Am, 497.31 (343.52, 606.50) vs. 353.11 (267.50, 487.91) nmol/L, P<0.001] than those in the non-ACS group. The serum DHEAS level and ratio in the ACS group were significantly lower than those in the non-ACS group [0.50 (0.40, 1.21) vs. 2.68 (1.56, 4.32) µmol/L, 1.00 (0.43, 1.68) vs. 3.17 (2.21, 4.54), both P<0.001]. When the serum DHEAS ratio cut-off point was 1.29, the sensitivity and specificity for differential diagnosis of ACS and non-ACS were 72.0% and 91.5% respectively. The ratio of DHEAS in the CPA group was lower [0.58 (0.27, 1.05) vs. 1.14 (1.04, 2.40), P<0.001] than that in the PBMAH group. When the serum DHEAS ratio cut-off point was 0.99, the sensitivity and specificity for differential diagnosis of CPA and PBMAH were 64.2% and 81.2% respectively. Conclusion: Corrected age-sex DHEAS ratio can assist in the functional assessment of adrenal space-occupying lesions.

Objective: To analyze the correlation between fatty liver index (FLI) and myocardial remodeling. Methods: For cross-sectional study, cluster sampling was used to conduct a follow-up study of "Risk evaluation of cancers in Chinese diabetic individuals: A longitudinal (REACTION) study" among communities of Gucheng and Pingguoyuan of Beijing from April 2015 to September 2015. According to the inclusion and exclusion criteria, 8 848 participants were selected. Biochemical indicators such as body mass index, waist circumference, triglycerides, and γ-glutamyl transpeptidase were detected to calculate the FLI. The correlation between FLI and myocardial remodeling was analyzed. Interventricular septal thickness (IVS), left atrial diameter (LAD), left ventricular end diastolic diameter (LVEDD), and the presence of diastolic dysfunction were measured by color doppler ultrasound. The participants were divided into Q1 group (FLI<30, 4 529 cases), Q2 group (30≤FLI<60, 2 762 cases), and Q3 group (FLI≥60, 1 557 cases) based on FLI levels. Single factor analysis of variance was used for inter-group comparison, logistic regression analysis was used to analyze the correlation between FLI and myocardial remodeling. Results: A total of 8 848 subjects were selected for the study (3 110 male and 5 738 female, mean age: 59.96 years). The IVS of Q1, Q2, and Q3 groups were (9.35±1.08), (9.73±1.22), and (10.07±1.31) mm, respectively. The LAD were (30.94±3.90), (33.37±4.12), and (34.98±4.47) mm, respectively. The LVEDD were (42.51±5.05), (44.43±5.10), and (46.06±5.52) mm, respectively. All increased with the increase of FLI (all P<0.001). FLI was an independent risk factor for IVS thickening, LAD increase, LVEDD increase, and diastolic function decrease. The respective risks for IVS thickening, LAD increase, LVEDD increase, and diastolic function decrease in a population with intermediate and higher FLI levels was 1.62 times (95%CI 1.39-1.89) and 2.53 times (95%CI 2.13-3.00); 2.71 times (95%CI 2.39-3.06) and 5.00 times (95%CI 4.12-6.08); 2.36 times (95%CI 1.85-3.00) and 4.33 times (95%CI 3.33-5.62); and 1.90 times (95%CI 1.63-2.19) and 1.95 times (95%CI 1.60-2.37) than those with lower FLI levels. Conclusion: There is a certain relevance between FLI and myocardial remodeling.

Objective: To investigate the pathological characteristics of tumor regression and the expression level of chemoradiotherapy resistance-related molecular markers after preoperative concurrent radiochemotherapy in patients with locally advanced hypopharyngeal carcinoma. Methods: The clinical data of 44 patients with locally advanced hypopharyngeal carcinoma who underwent preoperative concurrent radiochemotherapy in the Department of Head and Neck Surgery of Shandong Otolaryngology Hospital from August 2016 to August 2020 were retrospectively analyzed. All patients received preoperative concurrent chemotherapy and radiotherapy. After radiochemotherapy, electronic laryngoscopy and imaging examination were performed to assess the tumor regression status. After 4 weeks, surgical resection was performed, and the specimens of the primary focus were processed as continuous pathological sections. After operation, HE staining and TdT-mediated dUTP nick-end labeling (TUNEL) method were used to detect the distribution characteristics and apoptosis of the remaining cancer focus, and immunohistochemistry was performed to determine the proliferation of the remaining cancer focus and the expression of radiation resistance-related molecular markers [signal transducer and activator of transcription 3 (STAT3), hypoxia-inducible factor-1alpha (HIF-1α), sex determining region Y-box 2 (SOX2), and P53]. Results: A total of 44 patients were included, all of whom were male, with a mean age of (58.3±3.5) years. There were 40 cases of pyriform sinus carcinoma and 4 cases of posterior pharyngeal wall carcinoma. Twenty-nine cases were in stage T3 and 15 cases were in stage T4. There were 6 stage â ¢ cases and 38 stage â £ cases. According to the response evaluation criteria in solid tumors (RECIST), 13 patients achieved complete response (CR), 22 patients had partial response (PR), and 9 patients achieved stable disease (SD) after concurrent radiochemotherapy. The primary lesion resection methods included 19 cases of hypopharyngeal circumferential resection and 2 cases of total laryngectomy and partial hypopharyngeal resection. Twenty-three cases underwent supracricoid cartilage subtotal laryngectomy cricoid tongue fixation (CHP). Among 22 patients with PR, 10 had large PR (remission rate ≥70%) and 12 had small PR (remission rate <70%). The residual tumor was found in 30 patients (68.2%) after resection of all primary lesions by HE staining of pathological sections, of which 3 patients (3/13) with CR had residual cancer, all of which were focal residues. In large PR patients, residual cancer was detected in 6 cases (6/10), scattered in 4 cases, and focal residual in 2 cases, respectively. Large residual tumors were detected in small PR and SD patients. TUNEL method did not show any sign of apoptosis in 30 specimens with residual cancer focus, and the positive expression rate of Ki-67 was less than 10%. The expression of STAT3 (3.40±2.49 vs 5.23±3.02, t=-2.932, P=0.007) in 19 cases (63.3%) and HIF-1α (3.73±2.66 vs 6.97±3.05, t=-4.45, P<0.001) in 22 cases (73.3%) of residual cancer were significantly higher than those before radiochemotherapy. Other molecular markers showed no significant changes. All patients were followed up for 3 years. The 2-year survival rate was 59.3%, and the 3-year survival rate was 54.1%. Conclusions: Preoperative radiochemotherapy can make some patients with locally advanced hypopharyngeal carcinoma achieve complete or significant remission in clinical evaluation, but pathological detection still shows some residual cancer lesions with enhanced anti-apoptosis ability and decreased proliferation activity.

To summarize the clinical features and prognosis of pediatric mature B-cell non-Hodgkin lymphoma (mB-NHL) with digestive tract perforation. The clinical manifestations, laboratory and imaging examinations, treatment and outcomes of mB-NHL children complicated with digestive tract perforation admitted to Beijing Children's Hospital of Capital Medical University from January 2016 to June 2023 were retrospectively analyzed. A total of 12 patients were included, with 11 males and 1 female, aged 0.8-16.0 (7.5±5.4) years. Among them, there were 10 cases of Burkitt lymphoma, 1 case of high-grade B-cell lymphoma (HGBL) and 1 case of diffuse large B-cell lymphoma (DLBCL), respectively. Intestinal involvement was involved in all cases, with St.Jude staging ranging from stage â ¢ to â £. Eleven cases had large abdominal mass. In 7 cases, abdominal X-ray examination showed free gas under the diaphragm. Eleven cases experienced digestive tract perforation after chemotherapy, and the time of perforation after initiation of chemotherapy was 2.0-111.0 (41.2±33.6) days. The most common site of perforation was ileum (6 cases), followed by gastric wall (2 cases), jejunum (1 case), colon (1 case) and appendix (1 case). Eight patients underwent surgery, and the time between surgery and re-chemotherapy was 7.0-45.0 (17.6±12.0) days. One case with perforation before chemotherapy died after giving up treatment. The remaining 11 cases received conservative treatment or surgical intervention, followed by regular chemotherapy after symptom and infection control. The follow-up time was 6.0-82.0 (45.0±26.1) months, and all survived.

Objective: To explore the relationship between insomnia and osteoporosis. Methods: Mendelian randomization (MR) analysis were used in this study. The single nucleotide polymorphisms (SNPs) related to insomnia from genome-wide association analysis research data were selected as the instrumental variables by using inverse variance weighted (IVW), MR-Egger regression, weighted median method, maximum likelihood, penalized weighted median estimator, and Mendelian randomization robust adjusted profile score (MR-RAPS) to determine the causal relationship between insomnia and osteoporosis. Odds ratio (OR) and 95% confidence interval (CI) values were used to evaluate the association between insomnia and osteoporosis. Cochran's Q-test was used to detect heterogeneity of SNPs, MR-Egger regression was used to test for level pleiotropy, and the leave-one-out method was used to test sensitivity, MR pleiotropy residual sum and outlier (MR-PRESSO) method and radial MR were used to detect erroneous outliers. Results: The screening criteria were set based on the three major assumptions of MR; finally, 31 SNPs were included in the MR analysis. The results of MR causal effect analysis using the IVW method showed that insomnia increased the risk of osteoporosis by about 0.7% (OR=1.007, 95%CI 1.001-1.014, P=0.044); heterogeneity testing showed heterogeneity between SNPs (Q=57.91, P<0.001); and the MR- Egger intercept test did not indicate horizontal pleiotropy in this study (intercept value=3.807×10-5, P=0.888). Leave-one-out method showed that no single SNP had a significant impact on the overall results. No abnormal SNP was detected according to the MR-PRESSO results (P=0.059), and radial MR did not detect any outliers. Conclusion: Mendelian randomization analysis showed that insomnia can increase the risk of osteoporosis.

Objective: To investigate the value of serum dehydroepiandrosterone sulfate (DHEAS) in the differential diagnosis of primary bilateral macronodular adrenal hyperplasia (PBMAH) from nonfunctional adenoma tumors (NFA), adrenocortical adenoma (ADA) and Cushing's disease (CD). Methods: A cross-sectional study. The clinical data of 302 patients with PBMAH, NFA, ADA and CD diagnosed and treated in the First Medical Center of PLA General Hospital from January 2010 to June 2021 were retrospectively analyzed. Among them, 97 were males and 205 were females, aged (45.7±7.2) years. The area under receiver operating characteristic (ROC) curve was used to evaluate the DHEAS ratio (serum DHEAS value divided by the lower limit of normal reference range for the corresponding age and sex) and the 8â¶00 adrenocorticotropic hormone (ACTH) level in the differential diagnosis of PBMAH from NFA, ADA and CD. The maximum value of Youden index was cut-off value. Results: Among the 302 patients, 33 were in PBMAH group, 125 were in NFA group, 67 were in ADA group, and 77 were in CD group. The DHEAS ratio in CD group, NFA group, PBMAH group and ADA group decreased successively, with values of 6.34(4.44, 9.93), 3.37(2.24, 4.79), 1.14(1.04, 2.40) and 0.58(0.27, 1.05), respectively. There was statistical significance among all groups (all P<0.01). The area under the ROC curve for distinguishing PBMAH from NFA, ADA and CD were 0.803, 0.741 and 0.930, and the cut-off value were 2.59, 0.99 and 2.92, respectively. The sensitivity was 66.1%, 64.2% and 87.9%, respectively. The specificity was 81.8%, 81.2% and 85.7%. According to the level of 8â¶00 ACTH, PBMAH was divided into ACTH-inhibited group (ACTH<2.2 pmol/L,n=18) and ACTH-non-inhibited group (ACTH≥2.2 pmol/L, n=15).The DHEAS ratio in ACTH-non-inhibited PBMAH group was higher than that in ACTH-inhibited PBMAH group(P<0.01).The area under ROC curve of DHEAS ratio for identifying ACTH-non-inhibited PBMAH and CD was 0.877, the cut-off value was 4.55, the sensitivity was 93.3%, and the specificity was 75.3%. If the DHEAS ratio combined with 8â¶00 ACTH was used as a differential diagnostic indicator, the area under the ROC curve for distinguishing ACTH-non-inhibitory PBMAH from CD can reach 0.967, with the sensitivity of 100.0% and the specificity of 81.8%. Conclusions: DHEAS ratios is different in PBMAH, NFA, ADA and CD patients, which can assist in the differential diagnosis of PBMAH from NFAãADA and CD patients, especially in the differential diagnosis of ACTH-non-inhibited PBMAH patients and CD patients.

Objective: To explore the value of the midnight 1 mg dexamethasone suppression test combined with adrenocorticotropic hormone (ACTH) stimulation test in the diagnosis of primary aldosteronism (PA) subtypes. Methods: A cross-sectional study. Clinical data of patients diagnosed with PA at the First Medical Center of Chinese PLA General Hospital from January 2020 to September 2022, who completed the midnight 1 mg dexamethasone suppression test combined with ACTH stimulation test, were analysed retrospectively. The clinical characteristics and trial results of patients with aldosterone-producing adenoma (APA) and idiopathic hyper aldosteronism (IHA)were compared. The efficacy of the midnight 1 mg dexamethasone suppression test combined with ACTH stimulation test in distinguishing APA and IHA was evaluated by drawing receiver operating characteristic (ROC) curves, and the cut-off value of the diagnostic indicator was determined with the maximum Youden index. Results: A total of 82 patients with PA were included, including 43 males and 39 females, aged (50.8±11.4) years old. They were divided into APA group (n=49) and IHA group (n=33) based on PA subtype. There was no statistically significant difference in body mass index, systolic and diastolic blood pressure between the two groups (all P>0.05). The blood potassium and orthostatic renin levels in the APA group were lower than those in the IHA group, and the differences were statistically significant (all P<0.001). The orthostatic plasma aldosterone concentration (PAC), orthostatic aldosterone to renin ratio (ARR), PAC before and after captopril challenge test(CCT), ARR after CCT, PAC before and after saline infusion test (SIT), and the proportion of unilateral lesions in the APA group were all higher than those in the IHA group, and the differences were statistically significant (all P<0.001). After the midnight 1 mg dexamethasone suppression test combined with ACTH stimulation test (30, 60, 90, 120 min), the PAC and PAC/cortisol levels in the APA group were significantly higher than those in the IHA group (all P<0.05). The PAC at 90 min showed the highest diagnostic capability according to the area under the ROC(AUC) (0.930,95%CI:0.874-0.986), and the Youden index was the highest at a PAC cut-off value of 39.05 ng/dl(0.766). The sensitivity and specificity for distinguishing APA from IHA were 91.8% and 84.8%, respectively. Conclusions: The midnight 1 mg dexamethasone suppression test with ACTH stimulation test could be useful for differentiating the subtypes of PA. Among them, the PAC and PAC/cortisol at 90 min showed best diagnostic efficacy.

Objective: To examine the feasibility and clinical effect of all-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening for Achilles tendon contracture. Methods: This is a retrospective case series study. From February 2021 to February 2023, the clinical data of 24 patients (30 feet) with Achilles tendon contracture treated with all-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening were analyzed retrospectively. There were 10 males and 14 females, aged (32.8±16.1) years (range: 9 to 62 years). There were 8 cases of left side only, 10 cases of right side only and 6 cases of bilateral. There were 14 cases (16 feet) of foot varus, 4 cases (6 feet) of foot valgus, and 6 cases (8 feet) without deformity. All patients underwent all-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening. The surgical effects were evaluated using the maximum dorsal extension angle of ankle joint in knee extension position, the visual analogue scale (VAS) of pain, the American Orthopedic Foot and Ankle Society ankle-hindfoot score(AOFAS-AH). Paired sample t test was used to compare the scores before and after operation. Results: All patients successfully completed the operation, and the operation time of Achilles tendon lengthening was (22.0±5.7)minutes (range: 15 to 35 minutes) and the intraoperative blood loss was (6.5±2.7)ml (range: 2 to 15 ml). All patients primarily healing without any complications such as sural nerve injury, Achilles tendon rupture, important blood vessel injury, and obvious decrease of lift heel strength of achilles tendon. All 24 patients were followed up for (17.2±4.5) months (range: 12 to 28 months). One patient suffered from lift heel's weakness in one foot after operation, and recovered after repeated lift heel functional exercises. The ankle dorsiflexion function of two patients with calf triceps spasm were not improved after operation, and it was obviously improved after botulinum toxin injection. At the last follow-up, the maximum dorsal extension angle of ankle joint in knee extension position increased from -9.2°±7.6°(range:-25° to 5°) preoperatively to 14.5°±7.0°(range:0° to 28°)(t=24.83, P<0.01); the VAS score was reduced from (4.5±1.7) points (range:1 to 8 points) preoperatively to (1.5±0.9) points (range:0 to 3 points) (t=9.53, P<0.01), the AOFAS-AH was increased from (60.5±11.4)points (range:38 to 85 points) to (90.8±5.4) points (range:80-100 points)(t=14.21, P<0.01). Conclusions: All-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening for Achilles tendon contracture not only provides Achilles tendon lengthening, but also avoids complications such as Achilles tendon rupture and sural nerve injury. It is an effective method for the treatment of Achilles tendon contracture.

Objective: To study the relationship between hemoglobin glycation index (HGI) and blood lipid indices such as low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and plasma atherogenic index (AIP). Methods: This cross-sectional study included 16 049 participants from the Beijing Apple Garden community between December 2011 and August 2012. The subjects were divided into three groups based on the HGI quartile: low (n=5 388), medium (n=5 249), and high (n=5 412). The differences in blood lipid indicators between different HGI groups were compared and multivariate logistic regression model was established to analyze the association between HGI and dyslipidemia. And multivariate logistic regression model was established to analyze the relationship between HGI and blood lipid indicators in different glucose metabolism populations. Results: There were 16 049 participants in all (mean age: 56 years), including 10 452 women (65.1%). They were classified into normal glucose tolerance (9 093 cases), prediabetes (4 524 cases), and diabetes (2 432 cases) based on glucose tolerance status. In the general population, with the increase of HGI, LDL-C, non-HDL-C, and AIP gradually increased (all P values for trends were <0.05), and the proportion of abnormalities increased significantly (χ2=101.40, 42.91, 39.80; all P<0.001). A multivariate logistic regression model was established, which suggested a significant correlation between HGI and LDL-C, non-HDL-C, and AIP (all P<0.05), after adjusting for factors such as age, sex, fasting blood glucose, hypertension, body mass index, smoking, and alcohol consumption. In the overall population, normal glucose tolerance group, and diabetes group, HGI had the highest correlation with non-HDL-C (OR values of 1.325, 1.678, and 1.274, respectively); in the prediabetes group, HGI had a higher correlation with LDL-C (OR value: 1.510); and in different glucose metabolism groups, AIP and HGI were both correlated (OR: 1.208-1.250), but not superior to non-HDL-C and LDL-C. Conclusion: HGI was closely related to LDL-C, non HDL-C, and AIP in the entire population and people with different glucose metabolism, suggesting that HGI may be a predictor of atherosclerotic cardiovascular disease.

Objective: To provide supports for the cancer prevention and control strategies in China by comparing the disease burden, epidemic trends, 5-year relative survival rate and major determinants of common cancers between China and the United States. Methods: A descriptive secondary analysis was conducted using data extracted from the GLOBOCAN database, the Surveillance, Epidemiology, and End Results database, Global Burden of disease 2019 database, and previous studies. The main indicators included the cases of malignant tumors in different sites, the cases of deaths, the age-standardized incidence (world standard incidence) and mortality (world standard mortality), the 5-year relative survival rate, and population attributable fraction (PAF). Results: In 2022, an estimated 4.825 million new cases and 2.574 million deaths of malignant neoplasms in China. The world standard incidence rate (201.6/100 000) in China was lower than that in the United States (367.0/100 000), and the world standard mortality rate (96.5/100 000) was higher than that in the United States (82.3/100 000). Lung cancer ranked first in the disease burden of malignant tumors in China, the new cases and deaths accounted for 22.0% and 28.5% of all malignant tumors, respectively. The top three malignant tumors in China were breast cancer (11.5%), prostate cancer (9.7%) and lung cancer (9.5%), which were also among the top five causes of death. However, the second to fifth leading causes of death from malignant tumors in China were digestive system tumors (liver cancer 12.3%, stomach cancer 10.1%, colorectal cancer 9.3%, and esophageal cancer 7.3%). From 2000 to 2018, the world standard incidence of malignant tumors showed an increasing trend and the world standard mortality of malignant tumors showed a decreasing trend in China, while the world standard incidence and mortality of malignant tumors in the United States showed a significant decreasing trend after 2000. The incidence of breast cancer, colorectal cancer and thyroid cancer increased rapidly in China, while the incidence and mortality of stomach cancer, liver cancer and esophageal cancer decreased, but they still had a heavy disease burden. From 2003 to 2015, the overall 5-year relative survival rate of malignant tumors increased from 30.9% to 40.5% in China. However, with the exception of esophageal cancer, the 5-year relative survival rates of other major malignant tumors were lower than those in the United States. In 2019, the PAF of malignant tumors death attributable to potential modifiable risk factors was 48.3% in China, which was similar to the United States (49.8%). Of these, smoking was the most important attributable risk factor, and the PAF was more than 30% both in China and the United States. In addition, about 18.8% of malignant tumors were caused by preventable chronic infections, such as hepatitis B virus and Helicobacter pylori, while less than 4% of malignant tumors in the United States were caused by infection. Conclusions: China has made great progress in the prevention and treatment of malignant tumors, but it still faces a serious disease burden. The cancer spectrum is changing from developing countries to developed countries. We should pay attention to modifiable factors, take comprehensive measures, and prevent cancer scientifically.

Objective: To determine the total and age-specific cut-off values of total prostate specific antigen (tPSA) and the ratio of free PSA divided total PSA (fPSA/tPSA) for screening prostate cancer in China. Methods: Based on the Chinese Colorectal, Breast, Lung, Liver, and Stomach cancer Screening Trial (C-BLAST) and the Tianjin Common Cancer Case Cohort (TJ4C), males who were not diagnosed with any cancers at baseline since 2017 and received both tPSA and fPSA testes were selected. Based on Cox regression, the overall and age-specific (ï¼60, 60-ï¼70, and ≥70 years) accuracy and optimal cut-off values of tPSA and fPSA/tPSA ratio for screening prostate cancer were evaluated with time-dependent receiver operating characteristic curve (tdROC) and area under curve (AUC). Bootstrap resampling was used to internally validate the stability of the optimal cut-off value, and the PLCO study was used to externally validate the accuracy under different cut-off values. Results: A total of 5 180 participants were included in the study, and after a median follow-up of 1.48 years, a total of 332 prostate cancer patients were included. In the total population, the tdAUC of tPSA and fPSA/tPSA screening for prostate cancer were 0.852 and 0.748, respectively, with the optimal cut-off values of 5.08 ng/ml and 0.173, respectively. After age stratification, the age specific cut-off values of tPSA in the <60, 60-<70, and ≥70 age groups were 3.13, 4.82, and 11.54 ng/ml, respectively, while the age-specific cut-off values of fPSA/tPSA were 0.153, 0.135, and 0.130, respectively. Under the age-specific cut-off values, the sensitivities of tPSA screening for prostate cancer in males <60, 60-70, and ≥70 years old were 92.3%, 82.0%, and 77.6%, respectively, while the specificities were 84.7%, 81.3%, and 75.4%, respectively. The age-specific sensitivities of fPSA/tPSA for screening prostate cancer were 74.4%, 53.3%, and 55.9%, respectively, while the specificities were 83.8%, 83.7%, and 83.7%, respectively. Both bootstrap's internal validation and PLCO external validation provided similar results. The combination of tPSA and fPSA/tPSA could further improve the accuracy of screening. Conclusion: To improve the screening effects, it is recommended that age-specific cut-off values of tPSA and fPSA/tPSA should be used to screen for prostate cancer in the general risk population.

Objective: To analyze the incidence and the related risk factors of retropharyngeal lymph node metastasis in patients with hypopharyngeal squamous cell carcinoma, evaluate the accuracy of preoperative enhanced CT in judging retropharyngeal lymph node metastasis, and investigate the impact of retropharyngeal lymph node metastasis on the prognosis. Methods: Retrospective analyses were made on 398 patients with hypopharyngeal squamous cell carcinoma who underwent surgery as the primary therapy and accepted retropharyngeal lymph node exploration and clearance during surgery in Shandong Provincial ENT Hospital from January 2014 to December 2019. Multivariate logistic regression analysis was used to clarify the related risk factors of retropharyngeal lymph node metastasis. Multivariate Cox regression analysis was used to investigate the impact of retropharyngeal lymph node metastasis on prognosis. The retropharyngeal lymph nodes of 218 cases with available preoperative enhanced CT images were evaluated by two experienced radiologists and compared with postoperative pathological results. Results: Retropharyngeal lymph node metastasis were confirmed in 54 of 398 (13.6%) cases according to postoperative pathology. The sensitivity and specificity of preoperative enhanced CT in the diagnosis of retropharyngeal lymph node metastasis were 34.6% and 91.1%, respectively, and the overall accuracy was 84.4%. Multivariate logistic regression analysis showed that the site of the primary lesion and pathological N stage were independent risk factors for retropharyngeal lymph node metastasis in hypopharyngeal squamous cell carcinoma. Patients with primary lesion located in the posterior wall of hypopharynx (OR=4.83, 95% CI: 1.27-18.40), N2 stage (OR=6.30, 95% CI: 2.25-17.67), and N3 stage (OR=26.89, 95% CI: 5.76-125.58) were prone to retropharyngeal lymph node metastasis. The 5-year overall survival rate of the 398 patients was 50.4%, and the 5-year disease-free survival rate was 48.3%. Multivariate Cox regression analysis showed that T stage, N stage, retropharyngeal lymph node metastasis, and radiotherapy were independent influencing factors for overall survival (T stage: HR=1.28, 95% CI: 1.06-1.54; N stage: HR=1.26, 95% CI: 1.14-1.40; retropharyngeal lymph node metastasis: HR=2.13, 95% CI: 1.47-3.08; radiotherapy: HR=0.54, 95% CI: 0.38-0.76) and disease-free survival of patients with hypopharyngeal squamous cell carcinoma (T stage: HR=1.26, 95% CI: 1.06-1.51; N stage: HR=1.25, 95% CI: 1.13-1.37; retropharyngeal lymph node metastasis: HR=2.24, 95% CI: 1.56-3.21; radiotherapy: HR=0.55, 95% CI: 0.40-0.77). Conclusions: Metastasis of retropharyngeal lymph nodes in hypopharyngeal squamous cell carcinoma is not rare. Enhanced CT is of low accuracy and limited value in diagnosing retropharyngeal lymph node metastasis. Primary lesions located in the posterior wall of the hypopharyngx, N2 stage, and N3 stage are independent high-risk factors for retropharyngeal lymph node metastasis. The prognosis of hypopharyngeal cancer patients with retropharyngeal lymph node metastasis is worse, and active surgical exploration and clearance can effectively reduce the mortality caused by retropharyngeal lymph node metastasis.

Methods: The study was a retrospective case-series research.The data of 17 adult patients (17 feet) with symptomatic talocalcaneal coalitions,treated with PASTA from March 2018 to February 2022 in Xuzhou Central Hospital were collected.This procedure involved 10 males and 7 females,aged (42.4±7.5) years(range:31 to 58 years).There were 9 cases on the right side and 7 cases on the left side.According to the Rozansky classification,there were 4 cases of type â ,7 cases of type â ¡, 3 cases of type â ¢,3 cases of type â £.The following items such as wound healing and bony union of the subtalar joint were observed.Clinical assessment was performed using pain visual analogue scale (VAS),American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores and 36-item short form health survey (SF-36) scores.The paired t test was used for data comparison. Results: The follow-up time was (24.8±6.9) months(range:12 to 40 months).There were no complications such as wound infection,deep vein thrombosis,nonunion,or screw breakage.One patient with preoperative spasm,relieved after the second surgical procedure (peroneal brevis tendon lengthening).The union time of the subtalar joint was (8.8±2.2) weeks(range:6 to 12 weeks).At the final follow-up,the VAS decreased from (6.4±1.3) to (1.3±0.9)(t=14.114,P<0.01), the AOFAS ankle-hindfoot score increased from (49.0±8.1) to (90.0±5.1)(t=38.782,P<0.01),and the SF-36 score increased from (50.8±9.5) to (91.0±4.9)(t=20.468,P<0.01). Conclusion: PASTA for adult patients presenting with symptomatic talocalcaneal coalition offers advantages of minimal trauma,fast recovery,and few complications,which is an effective method.
ABSTRACT
Objective: To explore the characteristics of the association between the triglyceride glucose (TyG) index and nonfatal cardio-cerebrovascular disease risk in a community population. Method: This was a prospective cohort study. From December 2011 to April 2012, the first investigation was conducted among subjects with more than 40-year old who were from Shijingshan district and Pingguoyuan community in Beijing. The second investigation was conducted from April to October 2015. All the subjects were divided into three groups according to the tertile of the TyG index at baseline. The multivariate Cox proportional risk regression model was established to explore the correlation between the TyG index and nonfatal cardio-cerebrovascular disease risk and the Kaplan-Meier survival curve of the TyG index group was drawn. Subgroup analyses were performed according to age, gender, body mass index, type 2 diabetes mellitus (T2DM), hypertension, and hyperlipidemia to determine the correlation characteristics between the TyG index and nonfatal cardio-cerebrovascular disease among subgroups. Results: A total of 9 577 subjects were finally included to analyze. The mean follow-up time of this study was (34.14±3.84) months. During the follow-up, 363 subjects (3.8%) occurred nonfatal cardio-cerebrovascular disease. The multivariate Cox regression analysis results showed that the hazard ratio (HR) of nonfatal cardio-cerebrovascular disease in the high TyG index group was 1.54 (95%CI 1.19-1.98), 1.60 (95%CI 1.23-2.10), and 1.57 (95%CI 1.20-2.05) in the three models, compared with the low TyG index group. The Kaplan-Meier analysis showed that the risk of nonfatal cardio-cerebrovascular disease increased from the low-TyG index group to the high-TyG index group (P=0.015). In the six subgroups analysis, only gender was shown to have a significant interaction effect with the TyG index and nonfatal cardio-cerebrovascular disease risk. In the female population, the risk of nonfatal cardio-cerebrovascular disease is significantly increased with the increase in the TyG index level (P<0.001). Conclusions: A high TyG index is independently related to the increased risk of nonfatal cardio-cerebrovascular disease in the Beijing community population. Gender has a significant interaction with the TyG index and nonfatal cardio-cerebrovascular disease risk. Therefore, the TyG index may be a useful marker to predict the nonfatal cardio-cerebrovascular disease risk of a community population.

Objective: To summarize the correlation between anterior pituitary function and tumor size in patients with different hormone-secreting pituitary adenomas. Methods: This was a retrospective case series study. The clinical data of 1 946 patients with pituitary adenoma hospitalized in the First Medical Center of Chinese PLA General Hospital from January 1, 2005, to December 31, 2020, were collected. The correlation between tumor size and anterior pituitary hormone levels was analyzed using Spearman rank correlation analysis in different types of pituitary adenomas. Results: The median age of the 1 946 patients was 45.1 years, of which 857 (44.0%) were men. The maximum tumor diameter of the patients [M (Q1, Q3)] was 22 (14, 30) mm. Tumor size in nonfunctioning adenomas (n=1 191) was negatively correlated with adrenocorticotropic hormone (ACTH) (r=-0.11, P<0.001), growth hormone (r=-0.13, P<0.001), and luteinizing hormone (men: r=-0.26, P<0.001, women: r=-0.31, all P<0.001). The tumor size of somatotropic adenomas (n=297) was positively correlated with growth hormone (r=0.46, P<0.001), but negatively correlated with male testosterone (r=-0.41, P<0.001). The tumor size of ACTH-secreting pituitary adenomas (n=155) was positively correlated with the ACTH level at 8â¶00 AM (r=0.25, P<0.001); however, no correlation was found with cortisol at 8â¶00 AM (P>0.05). The tumor size of prolactinomas (n=303) was positively correlated with the prolactin level (men: r=0.34, P=0.001; women: r=0.13, P=0.070). Conclusions: The correlation between the function of the anterior pituitary and size of the tumor depends on the cellular origin of the pituitary adenoma and specific type of hormone secretion. In somatotroph adenomas, ACTH-secreting pituitary adenomas, and prolactinomas, there is a positive correlation between tumor size and level of hormones secreted by the corresponding tumors. In patients with nonfunctioning adenomas, the tumor size was negatively correlated with the hormone levels of the pituitary-adrenal and pituitary-growth hormone axes.

Malignant liver tumors have a high incidence and mortality rate. Therefore, it is of great significance to promptly learn about tumor advancement status through relevant examinations for patients' follow-up, diagnosis, and therapy as well as the improvement of the five-year survival rate. The primary lesions and intrahepatic metastases of malignant liver tumors have been better demonstrated in the clinical study with the use of various isotope-labeled fibroblast activating protein inhibitors because of their low uptake in liver tissues and high tumor/background ratio, which provides a new method for early diagnosis, precise staging, and radionuclide therapy. In light of this context, a review of the research progress of fibroblast-activating protein inhibitors for the diagnosis of liver malignant tumors is presented.
