Objective To investigate the screening results and factors affecting abnormal detection rates among high-risk groups of esophageal cancer and to explore effective intervention measures. Methods We investigated and collected the information on gender, education level, age, marital status, symptoms of reflux esophagitis (heartburn, acid reflux, belching, hiccup, foreign body sensation in the pharynx, and difficulty swallowing), consumption of pickled vegetables, salt use, and esophageal cancer incidence of villagers in a natural village in Wenfeng District, Anyang City, Henan Province. Changes in reflux esophagitis symptoms in the high-incidence area of esophageal cancer before and after 16 years were observed, and the relationship of such changes with esophageal cancer was analyzed. Results In 2008, 711 cases were epidemiologically investigated, including 213 cases with one of the symptoms of reflux esophagitis such as heartburn, acid reflux, belching, hiccups, foreign body sensation in the pharynx, and difficulty swallowing (sorted in accordance with the abovementioned symptoms; if there are multiple symptoms, then the former is taken); 55 cases with at least two related symptoms, among which the most symptom was heartburn in 108 cases (15.1%); followed by acid reflux, belching, etc. In 2024, the same group of people was investigated, and eight people were missing because of relocation. A total of 703 people were successfully investigated, of which 189 cases (26.8%) had one of the symptoms of reflux esophagitis, such as heartburn (sorted in accordance with relevant symptoms, if there are multiple symptoms, then the former will be selected); 167 cases (23.7%) had at least two related symptoms, among which the most symptom was heartburn in 139 cases (19.7%); followed by acid reflux. Over 16 years, among the 703 people investigated, 45 cases had esophageal cancer and they had one or more of the abovementioned symptoms. No significant differences in the reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.26); no significant differences in the composition of reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.299). Conclusion The detection rate of reflux esophagitis-related symptoms in the population in a high-risk area of esophageal cancer has not decreased in the past 16 years, and the high-risk factors still exist. Esophageal cancer is closely related to reflux esophagitis, and clinical practice can provide early diagnosis and treatment for high-risk population.

Objective To investigate the relationship between tooth loss and the occurrence of esophageal cancer in a natural village in Wenfeng District, Anyang City, Henan Province. Methods A prospective cohort study was conducted to observe the occurrence of tooth loss and esophageal cancer among the asymptomatic residents of the natural village for 16 years from January 2008 to July 2024. Data were analyzed by chi-square test, binary logistic regression, and restricted cubic spline. Results Among the total population of 711 cases, 136 cases were lost to follow-up and 575 cases were included in the final statistics, including 45 cases with esophageal cancer. Significant statistical difference was found between esophageal cancer patients with and without tooth loss (P<0.05). Logistic regression analysis showed that tooth loss was associated with the occurrence of esophageal cancer (OR=3.977, 95%CI: 1.543-10.255). After the adjustment for confounders, tooth loss remained significantly associated with the occurrence of esophageal cancer (OR=3.038, 95%CI: 1.035-8.914). A nonlinear dose-response relationship was observed between the number of teeth lost and the incidence of esophageal cancer. When the number of teeth lost was less than 12, the risk of esophageal cancer increased with the number of teeth lost. When more than 12 teeth were lost, the risk of esophageal cancer decreased as the number of teeth lost increased. Conclusion Tooth loss is a risk factor for the occurrence of esophageal cancer in this natural village. When the number of teeth lost is less than 12, the risk of esophageal cancer increases with the number of teeth lost.

OBJECTIVE: This study aimed to investigate the impact of glycemic control and diabetes duration on subsequent myocardial infarction (MI) in patients with both coronary heart disease (CHD) and type 2 diabetes (T2D). METHODS: We conducted a retrospective cohort study of 33,238 patients with both CHD and T2D in Shenzhen, China. Patients were categorized into 6 groups based on baseline fasting plasma glucose (FPG) levels and diabetes duration (from the date of diabetes diagnosis to the baseline date) to examine their combined effects on subsequent MI. Cox proportional hazards regression models were used, with further stratification by age, sex, and comorbidities to assess potential interactions. RESULTS: Over a median follow-up of 2.4 years, 2,110 patients experienced MI. Compared to those with optimal glycemic control (FPG < 6.1 mmol/L) and shorter diabetes duration (< 10 years), the fully-adjusted hazard ratio ( HR) (95% Confidence Interval [95% CI]) for those with a diabetes duration of ≥ 10 years and FPG > 8.0 mmol/L was 1.93 (95% CI: 1.59, 2.36). The combined effects of FPG and diabetes duration on MI were largely similar across different age, sex, and comorbidity groups, although the excess risk of MI associated with long-term diabetes appeared to be more pronounced among those with atrial fibrillation. CONCLUSION Our study indicates that glycemic control and diabetes duration significant influence the subsequent occurrence of MI in patients with both CHD and T2D. Tailored management strategies emphasizing strict glycemic control may be particularly beneficial for patients with longer diabetes duration and atrial fibrillation.

Objective:This study aimed to explore the serum levels of soluble programmed cell death protein 1 (sPD-1) and soluble programmed cell death-ligand 1 (sPD-L1) in patients with spontaneous intracerebral hemorrhage (ICH) and their clinical value in the prognostic analysis.Methods:This prospective cohort study included patients aged ≥18 years admitted to the department of critical care medicine at the Affiliated Hospital of Zunyi Medical University between January 2022 and October 2024 with a first episode of ICH presenting within 24 hours of onset. Patients with hemorrhage caused by other causes (e.g., tumor, medication and trauma) or incomplete data were excluded. Based on 28-day all-cause mortality, patients were divided into survival group and non-survival group. According to the 60-day neurological outcome, patients were divided into good neurological outcome group and poor neurological outcome group. Clinical and imaging data were collected, along with venous blood samples obtained within 24 hours of admission to measure serum levels of sPD-1 and sPD-L1. Predictive indicators were identified using LASSO-Logistic regression analysis was used to identify predictive indicators, and a nomogram was constructed to visualize the prediction model. Model performances were evaluated using receiver operating characteristic curves, decision curve analysis, calibration curves, and the Hosmer-Lemeshow test.Results:A total of 155 patients were included: 101 in the survival group and 54 in the death group; 56 in the favorable neurological outcome group and 99 in the poor neurological outcome group. Serum sPD-1 concentrations were significantly lower in the death group and poor neurological outcome group compared to the survival group and favorable neurological outcome group, respectively. Conversely, serum sPD-L1 concentrations were significantly higher in the death group and poor neurological outcome group compared to the survival group and favorable neurological outcome group (all P < 0.05). Serum sPD-1 and sPD-L1 were identified as predictors of 28-day mortality risk. A nomogram incorporating seven indicators—brainstem hemorrhage, hemorrhage volume, obstructive hydrocephalus, surgical intervention, admission NIHSS score, and admission serum sPD-1 and sPD-L1 levels—demonstrated superior predictive performance [AUC=0.984 (95% CI: 0.968-1.000)] compared to sPD-1 alone (AUC=0.712) or sPD-L1 alone (AUC=0.753). Serum sPD-1 was a predictor of poor 60-day neurological outcome. A nomogram incorporating obstructive hydrocephalus, admission NIHSS score, and admission serum sPD-1 level [AUC=0.818 (95% CI: 0.754-0.882)] outperformed sPD-1 alone (AUC=0.637) or sPD-L1 alone (AUC=0.602). Conclusions:Serum levels of sPD-1 were significantly lower in the non-survivors and the patients with poor neurological outcomes compared to the survivors and the patients with good neurological outcomes. However, serum levels of sPD-L1 were significantly higher in the non-survivors and the patients with poor neurological outcome. Serum sPD-1 was an independent predictor of 28-day mortality risk and 60-day poor neurological outcome; serum sPD-L1 was an independent predictor of 28-day mortality risk. A nomogram prediction model incorporating sPD-1 and sPD-L1 demonstrated good predictive performance for mortality risk and poor neurological outcome.

OBJECTIVE: To investigate the anthropometric parameters that can accurately predict the diameter of the hamstring tendon graft, and to examine the correlation between disease etiology, duration, and graft diameter. METHODS: A retrospective analysis was conducted on data from 166 patients who underwent anterior cruciate ligament reconstruction using hamstring tendon autografts (semitendinosus and gracilis tendon) between January 2013 and December 2023. The cohort conprised 135 males and 31 females;the age ranged from 14 to 62 years old with an average of (28.87±10.46) years old. Pearson correlation coefficients, partial correlation coefficients, and stepwise multiple linear regression analysis were utilized to elucidate the relationship between the outcome variable (diameter of hamstring tendon grafts) and predictive variables (e.g., height). RESULTS: Correlation analysis revealed significant associations between the diameter of hamstring tendon grafts and height (r=0.379, P<0.001), weight (r=0.225, P=0.002), male gender (r=0.302, P<0.001), age(r=-0.218, P=0.002), and sports injury etiology (r=0.167, P=0.016). No significant correlations were found with surgical side, body mass index (BMI), or injury duration (P>0.05). Stepwise multiple linear regression analysis using a backward elimination method indicated that height was the sole significant predictive variable (R²=0.144, P<0.001), with the optimal predictive equation being:Graft size =2.636+0.029×Height (cm). Partial correlation analysis, after controlling for height, showed no significant association between age, gender, weight, and injury etiology with graft diameter. CONCLUSION Height is an effective predictive factor for the diameter of autologous hamstring tendon grafts. Factors such as gender, age, surgical side, body weight, and BMI are not influential to the diameter of the hamstring tendon grafts. Under the condition of the same height, there is no significant difference in the influence of these factors on the graft diameter. Preoperative physical activity level and the duration of injury do not significantly affect the diameter of the hamstring tendon grafts obtained during surgery. It is recommended to use the formula 'Graft Diameter=2.636 + 0.029 × Height (cm)' for preoperative prediction.

OBJECTIVE: To investigate lymph node metastasis (LNM) in the prostatic anterior fat pad (PAFP) of PCa patients after robot-assisted radical prostatectomy (RARP), and analyze the clinicopathological features and prognosis of LNM in the PAFP. METHODS: We retrospectively analyzed the clinicopathological data on 1 003 cases of PCa treated by RARP in the Department of Urology of PLA General Hospital from January 2017 to December 2022. All the patients underwent routine removal of the PAFP during RARP and pathological examination, with the results of all the specimens examined and reported by pathologists. Based on the presence and locations of LNM, we grouped the patients for statistical analysis, compared the clinicopathological features between different groups using the Student's t, Mann-Whitney U and Chi-square tests, and conducted survival analyses using the Kaplan-Meier and Log-rank methods and survival curves generated by Rstudio. RESULTS: Lymph nodes were detected in 77 (7.7%) of the 1 003 PAFP samples, and LNM in 11 (14.3%) of the 77 cases, with a positive rate of 1.1% (11/1 003). Of the 11 positive cases, 9 were found in the upgraded pathological N stage, and the other 2 complicated by pelvic LNM. The patients with postoperative pathological stage≥T3 constituted a significantly higher proportion in the PAFP LNM than in the non-PAFP LNM group (81.8% ［9/11］ vs 36.2% ［359/992］, P = 0.005), and so did the cases with Gleason score ≥8 (87.5% ［7/8］ vs 35.5% ［279/786］, P = 0.009). No statistically significant differences were observed in the clinicopathological features and biochemical recurrence-free survival between the patients with PAFP LNM only and those with pelvic LNM only. CONCLUSION The PAFP is a potential route to LNM, and patients with LNM in the PAFP are characterized by poor pathological features. There is no statistically significant difference in biochemical recurrence-free survival between the patients with PAFP LNM only and those with pelvic LNM only. Routine removal of the PAFP and independent pathological examination of the specimen during RARP is of great clinical significance.

BACKGROUND/OBJECTIVES: The study examined the association between homocysteine and diabetes mellitus in patients with H-type hypertension and assessed the possible effect modifiers. SUBJECTS/METHODS: This cross-sectional study included 1,255 eligible participants in the ‘H-type Hypertension Management and Stroke Prevention Strategic International Science and Technology Innovation Cooperation Project’ among rural Chinese people with H-type hypertension. A multivariate logistic regression model was used to evaluate the relationship between homocysteine and diabetes mellitus. RESULTS: The mean level of total homocysteine (tHcy) in the diabetes mellitus population was 19.37 μmol/L, which was significantly higher than the non-diabetic patients (18.18 μmol/L). When tHcy was analyzed as a continuous variable, the odds ratio (OR) of diabetes was 1.17 (95% confidence interval [CI], 1.01–1.35; per interquartile range). When tHcy was stratified according to the quintile, the ORs for diabetes were 2.86 (95% CI, 1.22–6.69) in the highest quintile (tHcy ≥ 20.60 μmol/L) compared to the reference group (tHcy < 12.04 μmol/L). When tHcy was grouped by 15 μmol/L and 20 μmol/L, patients with tHcy ≥ 20 μmol/L had a significantly (P = 0.037) higher risk of diabetes (OR, 2.03; 95% CI, 1.04–3.96) than in those with tHcy < 15 μmol/L. Subgroup analysis showed that the tHcy-diabetes association was unaffected by other variables. CONCLUSION In this study of rural Chinese people with H-type hypertension, the tHcy levels showed a positive association with diabetes mellitus. This independent association is unaffected by other potential risk factors.

Objective:To optimize the technical parameters related to the preparation of novel frozen human platelets and formulate corresponding protocol for its preparation.Methods:Novel frozen human platelets were prepared with O-type bagged platelet-rich plasma(PRP),the key technical parameters(DMSO addition,incubation time,centrifugation conditions,etc.)of the preparation process were optimized,and the quality of the frozen platelets was evaluated by routine blood tests,apoptosis rate,platelet activation rate and surface protein expression level.Results:In the preparation protocol of novel frozen human platelets,the operation of centrifugation to remove supernatant was adjusted to before the procedure of platelets freezing,and the effect of centrifugation on platelets was minimal when the centrifugation condition was 800 xg for 8 min.In addition,platelets incubated with DMSO for 30 min before centrifugation exhibited better quality after freezing and thawing.The indexes of novel frozen human platelets prepared with this protocol remained stable after long-term cryopreservation.Conclusion:The preparation technique of novel frozen human platelets was established and the protocol was formulated.It was also confirmed that the quality of frozen platelets could be improved by incubating platelets with DMSO for 30 min and then centrifuging them at 800 ×g for 8 min in the preparation of novel frozen human platelets.

Objective:To analyze the clinical characteristics and prognosis of acute pancreatitis (AP) in children, and provide reference for clinical prevention and treatment of AP in children.Methods:Based on the electronic medical record system of the Affiliated Hospital of Zunyi Medical University, the clinical data of children with AP in the hospital from January 2011 to December 2020 were retrospectively analyzed. According to the severity of the disease, the children were divided into mild acute pancreatitis (MAP) group and severe acute pancreatitis (SAP) group. The general data, laboratory tests and outcomes indicators of the two groups were collected and compared. The epidemiological characteristics of children with AP were analyzed. Multivariate Logistic regression was used to analyze the risk factors of SAP in children.Results:A total of 227 children with AP were enrolled, including 161 in MAP group and 66 in SAP group. The median age of children with AP was 12.00 (8.00, 16.00) years old, and 126 cases (55.51%) were male. The main initial clinical symptoms were abdominal pain, nausea, vomiting and abdominal distension (97.36%, 61.67% and 14.10%, respectively), 21 cases (9.25%) were admitted to intensive care unit (ICU), and 4 cases (1.76%) died in hospital due to sepsis, multiple organ dysfunction or traumatic shock. The epidemiological characteristics showed that the first onset age of AP was mainly 7-17 years old (85.02%); the main etiologies were biliary tract disease (29.96%), viral infection (29.07%) and idiopathic factors (19.82%). From 2011 to 2020, the number of children with AP showed a fluctuating trend, and from 2018 to 2020, the number of children with AP increased for three consecutive years. Compared with MAP group, the age of SAP group was significantly older, the proportion of female, the proportion of rural source, acute physiology and chronic health evaluationⅡ(APACHEⅡ), body mass index (BMI), and the levels of white blood cell count (WBC), C-reactive protein (CRP), hospitalization expenses, the proportion of AP caused by traumatic factors and drug factors in SAP group were significantly higher (all P < 0.05). The level of blood calcium and the proportion of AP caused by virus infection were significantly lower, and the length of hospital stay in SAP group was significantly longer (all P < 0.05). The multivariate Logistic regression analysis showed that APACHEⅡscore [odds ratio ( OR) = 1.495, 95% confidence interval (95% CI) was 1.293-1.728] and age ( OR = 1.352, 95% CI was 1.182-1.546) were closely related to SAP in children (all P < 0.001). Conclusion:Children with AP mostly occurs in preschool and adolescence, and the overall mortality is relatively low; biliary tract disease, viral infection and idiopathic factors are common causes; APACHEⅡ score and age may be risk factors for SAP in children.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
