This report presents a case of esophageal fistula with recurrent cervical abscess as the initial symptom. The patient underwent anterior cervical fracture reduction and internal fixation in 2021 due to trauma. In 2023, the patient received radiofrequency ablation for bilateral thyroid lobe lesions, after which recurrent cervical abscesses occurred over an 8-month period. Fiberoptic laryngoscopy with the biopsy channel insufflation method revealed a large esophageal fistula at the esophageal inlet. After removing the internal fixation plate, the patient received daily wound care, and serial fiberoptic laryngoscopy revealed spontaneous healing of the esophageal fistula. During the 1-year follow-up, no recurrence of cervical abscess was observed, and the esophageal fistula healed well.

OBJECTIVE: To investigate the current status of long-term quality of life in patients with severe acute pancreatitis (SAP) who have been cured and discharged, and to analyze the influencing factors affecting long-term quality of life in SAP cured patients after discharge. METHODS: A retrospective collection was conducted. Patients who were received standardized treatment before being cured and discharged from the hospital admitted to the first department of critical care medcine of the Second Affiliated Hospital of Anhui Medical University from January 2017 to December 2023 were enrolled. According to the 36-item short form health survey scale (SF-36) score, patients were divided into high score group (high quality of life, the top 50% of patients with total SF-36 score) and low score group (low quality of life, the bottom 50% of patients with total SF-36 score). The gender, age, history of hypertension and diabetes, etiology of pancreatitis, acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA), CT severity index (CTSI), laboratory indicators such as C-reactive protein (CRP), procalcitonin (PCT), blood glucose, and triglycerides upon admission, use of vasoactive drugs, non-invasive/high-flow ventilation, invasive ventilation, retroperitoneal puncture and drainage, open pancreatic surgery treatment and secondary infection during hospitalization were collected, as well as the retention of abdominal drainage tubes at discharge from hospital. Distribute follow-up questionnaires or telephone follow-up surveys through WeChat and Question Star programs to investigate the pancreatic secretion function, chronic abdominal pain, and recurrence of pancreatitis of patients after discharge. Multivariable Logistic regression was used to analyze the relevant factors affecting the long-term quality of life of cured patients with SAP. RESULTS: A total of 86 patients were ultimately enrolled. There were 43 patients in both the high and low score groups. Among 86 patients, 20 experienced acute pancreatitis recurrence, with a recurrence rate of 23.26%. Twenty-two (25.58%) experienced chronic abdominal pain after discharge, and 5 patients (5.81%) needed medication to relieve pain. Thirty-three patients (38.37%) had pancreatic exocrine dysfunction after discharge, characterized by abdominal distension, constipation or diarrhea. Twenty-two patients (25.58%) suffered from pancreatic endocrine dysfunction, and were diagnosed with diabetes. Univariate analysis showed that compared with the high score group, the low score group had more patients with hypertension, initial renal dysfunction, initial severe metabolic acidosis, initial serum calcium < 2.0 mmol/L, blood glucose > 11.1 mmol/L and cultured Gram positive bacteria (from blood/body fluid/pancreatic necrotic tissue) during treatment (48.84% vs. 16.28%, 60.47% vs. 32.56%, 18.60% vs. 4.65%, 88.37% vs. 62.79%, 55.81% vs. 30.23%, 34.88% vs. 13.95%), had higher CTSI score (6.60±1.61 vs. 5.77±1.32), lower hemoglobin level at discharge (g/L: 102.30±18.78 vs. 110.72±16.68), and a lower proportion of etiological interventions after discharge (34.88% vs. 67.44%), the differences were statistically significant (all P < 0.05). Multivariate Logistic regression analysis showed that hypertension [odds ratio (OR) = 4.814, 95% confidence interval (95%CI) was 1.196-19.378], initial serum calcium < 2.0 mmol/L (OR = 6.688, 95%CI was 1.321-33.873) and initial blood glucose > 11.1 mmol/L (OR = 6.473, 95%CI was 1.399-29.950) were risk factors for long-term quality of life in cured SAP patients (all P < 0.05), while post discharge prophylactic intervention was a protective factor for long-term quality of life (OR = 0.092, 95%CI was 0.020-0.425, P < 0.01). CONCLUSIONS Cured SAP patients have varying degrees of impaired secretion function and the possibility of recurrence of acute pancreatitis. Hypertension, initial serum calcium < 2.0 mmol/L and blood glucose > 11.1 mmol/L are independent influencing factors for low long-term quality of life in cured SAP patients. Prevention and intervention targeting the etiology of pancreatitis after discharge can improve the long-term quality of life of cured SAP patients.

OBJECTIVE: Cultivated Cordyceps sinensis powder has been used as clinical drug and healthy food to nourish the lung and kidney, which solves the problem of serious shortage of wild C. sinensis. This study aims to explore the chemical components and compared their anti-fibrotic effects in cultivated C. sinensis. METHODS: Nucleosides, sterols and polysaccharides were separated and purified from cultivated C. sinensis, and analyzed by high performance liquid chromatography, gas chromatography-mass spectrometry and chemical chromogenic methods, respectively. In high glucose-induced rat mesangial cell models, fibronectin and type 1 collagen were used as evaluation indicators. RESULTS: There were 10 kinds of nucleosides and one sterol in cultivated C. sinensis. The contents of nucleosides, sterols and polysaccharides in the cultivated C. sinensis were close to 2%, 0.55% and 4.4%, respectively. Furthermore, nucleoside, sterol and polysaccharide components exhibited varying degrees of anti-fibrotic activity. The nucleoside components and sterol components inhibited the expression of extracellular matrix more effectively in the three main components. CONCLUSION Cultivated C. sinensis remains the similar compounds with the wild C. sinensis, and nucleosides and sterols may be the main active substances that contribute to its anti-fibrotic effects. The project of this study may provide valuable information on further optimization of more effective remedies with few side effects based on cultivated C. sinensis.

Objective To investigate the characteristics of human papillomavirus (HPV) prevalence and genotype distribution of 18 535 cases in Yuncheng . Methods A sample of 18535 residents who underwent HPV testing in our hospital from August 2020 to September 2023 were enrolled, and HPV genotyping was done to all samples. Then the rate of HPV infection, age distribution, genotype distribution, and multiple infections were statistically analyzed. Results Of the 18,535 subjects included, a total of 4,639 tested positive for HPV, demonstrating a positive rate of 25.03%. The positive rate of HPV infection varied among different age groups (χ²=29.587, P<0.05), with higher rates found in <25 years old group (29.61%) and >60 years old group (25.89%). Overall, 23 genotypes, covering 5315 viruses, were detected. There were 5 low-risk genotypes with the highest percentage of HPV42 (9.29%), and there were 18 high-risk genotypes with HPV52, HPV58, HPV66 and HPV53, subtypes as the most frequent subtypes, accounting for 13.64%, 8.97%, 7.41% and 7.04%, respectively. The type of HPV infection was predominantly single infections, with an overall single infection rate of 21.62% (4008/18535), which accounted for 86.40% (4 008/4 639) of all positive cases, and a multiple genotype infections rate of 3.40% (631/18535). The 25-34 year old group accounted for the largest proportion of single infections (25.12%), while the <25 year old group accounted for the largest proportion of multiple genotype infections (30.74%). Conclusion The prevalence rate of HPV infection in Yuncheng is 25.03%, with a higher positive rate in the <25 years age group and the >60 years age group. A total of 23 HPV genotypes are detected, of which the main genotypes are HPV42, HPV58, HPV66 and HPV53, and the type of infection is dominated by single infections.

Polygala tenuifolia,commonly known as Yuanzhi(YZ)in Chinese,has been shown to possess anti-insomnia properties.However,the material basis and the mechanism underlying its sedative-hypnotic effects remain unclear.Herein,we investigated the active components and neurochemical mechanism of YZ extracts using liquid chromatography tandem mass spectrometry(LC-MS/MS)-based pharmaco-metabolomics and mass spectrometry imaging(MSI)-based spatial resolved metabolomics.According to the results,17 prototypes out of 101 ingredients in the YZ extract were detected in both the plasma and brain,which might be the major components contributing to the sedative-hypnotic effects.Network pharmacology analysis revealed that these prototypes may exert their effects through neuroactive ligand-receptor interaction,serotonergic synapse,dopaminergic synapse,and dopaminergic synapse,among other pathways.LC-MS/MS-based targeted metabolomics and Western blot(WB)revealed that tryptophan-serotonin-melatonin(Trp-5-HT-Mel)and tyrosine-norepinephrine-adrenaline(Tyr-Ne-Ad)are the key regulated pathways.Dopa decarboxylase(DDC)upregulation and phenylethanolamine N-methyltransferase(PNMT)downregulation further confirmed these pathways.Furthermore,MSI-based spatially resolved metabolomics revealed notable alterations in 5-HT in the pineal gland(PG),and Ad in the brainstem,including the middle brain(MB),pons(PN),and hypothalamus(HY).In summary,this study illustrates the efficacy of an integrated multidimensional metabolomics approach in unraveling the sedative-hypnotic effects and neurochemical mechanisms of a Chinese herbal medicine,YZ.

Objective:To explore the application of medical dialectics combined with problem-oriented teaching based on textbooks in hematology internship teaching.Methods:A total of 100 undergraduate students who practiced in the Department of Hematology of the First Hospital of Jilin University from 2022 to 2023 were selected as the research subjects. Students were randomly assigned to a control group and an observation group, with 50 students in each group. The control group received traditional teaching, while the observation group received medical dialectics combined with textbook-based problem-oriented teaching. We assessed the theoretical and operational scores, classroom performance, comprehensive abilities, and teaching satisfaction of two groups of students using t-test and χ 2 test in SPSS 22.0. Results:The theoretical and operational scores of the observation group were (94.26±5.35) points and (92.68±4.72) points, respectively. The theoretical and operational scores of the control group were (86.16±5.42) points and (81.52±5.28) points, respectively. The differences between the two groups were statistically significant ( P<0.001). The recognition rates were significantly higher by students in the observation group than in the control group ( P<0.05) in terms of improving learning efficiency, self-learning ability, understanding and comprehensive analysis of diseases, problem-solving ability, language and organizational expression ability, integration of theory and practice, clinical thinking ability, and independent thinking ability. The satisfaction with teaching was higher in the observation group than in the control group ( P<0.05) in terms of teaching attitudes, teaching methods, teaching arrangements, practicality of teaching content, clear explanation of teaching theories, and outstanding teaching objectives. Conclusions:The medical dialectics combined with textbook-based problem-oriented teaching can improve the assessment scores of medical students, while helping to cultivate their comprehensive abilities and develop good clinical diagnosis and treatment thinking.

Objective:To study the clinical characteristics and risk factors for hypertriglyceridemia-induced severe acute pancreatitis (HTG-SAP) complicated by acute kidney injury.Methods:The clinical data of HTG-SAP patients admitted to the Department of Critical Care Medicine of the Second Affiliated Hospital of Anhui Medical University from January 2014 to July 2022 were retrospectively collected, and divided into an AKI group and a non-AKI group according to whether AKI occurred. The general condition, laboratory data and clinical characteristics of the two groups were compared. Factors with statistically significant differences were screened for logistic regression analysis and a predictive model was constructed. We plotted the receiver operating characteristic curve and used the area under the curve (AUC) to evaluate the predictive ability of each predictor for HTG-SAP complicated with AKI.Results:A total of 91 patients were included, including 37 (40.7%) with AKI and 54 (59.3%) without AKI. The proportions of extrapancreatic infection, sepsis and multiple organ dysfunction syndrome, requiring mechanical ventilation, continuous renal replacement therapy (CRRT), retroperitoneal puncture, and surgical intervention were higher in the AKI group than in the non-AKI group (all P<0.05). The length of ICU stay, total length of hospitalization, and mortality rate in the AKI group were higher than those in the non-AKI group (all P<0.05). Multivariate logistic regression analysis showed that acute physiology and chronic health status scoreⅡ (APACHEⅡ) ( OR=2.069, 95% CI: 1.286-3.417, P=0.003), abdominal pressure ( OR=1.469, 95% CI: 1.108-1.958, P=0.007), and lactic acid ( OR=3.156, 95% CI: 1.013-9.831, P=0.047) were independent risk factors for AKI in HTG-SAP patients. The AUCs of the APACHEⅡ score, abdominal pressure, lactic acid level and combined prediction model were 0.951, 0.918, 0.837 and 0.986, respectively. Conclusions:Patients with HTG-SAP complicated with AKI were more likely to have complications related to extrapancreatic infection, sepsis and multiple organ dysfunction, and the proportion of mechanical ventilation, CRRT, retroperitoneal puncture and surgical intervention required during hospitalization was greater, the lengths of ICU stay and total hospital stay were longer, and the mortality rate was higher. APACHEⅡ score, abdominal pressure and lactic acid were independent risk factors for HTG-SAP concurrent AKI, and the prediction model established based on these three factors had higher value in predicting HGT-SAP concurrent AKI

Objective:To explore the relevance between secondary retroperitoneal infection, as well as the outcomes, and the approach of intensive care unit (ICU) admission for the patients suffered from acute pancreatitis.Methods:Patients with acute pancreatitis admitted to the ICU of the Second Affiliated Hospital of Anhui Medical University from January 2013 to July 2022 were retrospectively analyzed. According to ICU admission approaches, the patients were divided into the emergency group (first admission or transferred from the emergency department) and the delayed group (transferred from the general wards due to disease evolution). Patients were also divided into retroperitoneal infection group and non-retroperitoneal infection group according to whether retroperitoneal infection was accompanied. Patients' baseline data including gender, age, underlying diseases, laboratory test indicators, acute physiology and chronic health evaluationⅡ score (APACHEⅡ), sequential organ failure assessment (SOFA), computed tomography severity index (CTSI), bedside index of severity in acute pancreatitis (BISAP), and acute complications were collected. Univariate and multivariate logistic regression was used to analyze the risk factors of retroperitoneal infection in patients with acute pancreatitis.Results:A total of 271 patients with acute pancreatitis were enrolled, including 95 cases in the emergency group and 176 cases in the delayed group. The cohort included 71 cases with and 200 cases without retroperitoneal infection development. The incidence of retroperitoneal infection and the 30-day mortality of patients in the delayed group, which was observed with a significantly longer ICU stay (days), [(15.4±21.3) vs. (8.6±10.8), P<0.05], were significantly higher than those in the emergency group [retroperitoneal infection incidence rate: 31.82% (56/176) vs.15.79%(15/95), 30-day mortality: 13.64%(24/176) vs. 4.21%(4/95), both P<0.05]. Univariate Logistic analysis showed significant differences in diabetes, APACHEⅡ, SOFA, CTSI and BISAP score, urea nitrogen, creatinine, blood calcium, D-D dimer, peritoneal puncture catheter drainage and ICU transferred from general wards due to disease evolution between the retroperitoneal infection group and the non-retroperitoneal infection group. Multivariate Logistic regression analysis showed that diabetes, SOFA score, CTSI score, peritoneal puncture catheter drainage and transfered from general wards to ICU due to disease evolution were independent risk factor for retroperitoneal infection in acute pancreatitis patients[odds ratio were 3.379, 1.150, 1.358, 3.855, 2.285, respectively]. Conclusions:Acute pancreatitis patients in ICU transferred from general wards are more likely to develop retroperitoneal infection, and have a higher risk of mortality and a longer ICU stay. Delayed admission to ICU, diabetes, SOFA score, CTSI score and peritoneal puncture catheter drainage are independent risk factors for retroperitoneal infection in patients with acute pancreatitis.

It is a unity of the spirit of patriotism, humanitarianism, scientific exploration, and dedication, and a valuable resource and vivid textbook for medical students to carry out professional spirit education. Promoting Wu Liande’s spirit in the new era is not only conducive to inspiring the patriotism of medical students, bravely undertaking the mission of the times, and devoting themselves to the cause of human health, but also conducive to guiding medical students to refine benevolence and skill, and fulfill the sacred oath of medical students. To cultivate the professional spirit of medical students with Wu Liande’s spirit, it is necessary to achieve the "integration of specialized courses and ideological and political education" , promote the collaborative development of ideological and political courses and curriculum ideological and political education, innovate teaching methods and use modern information technology to empower Wu Liande’s spirit to be visualized and expressed, and take discipline practice as the starting point to expand the new path of professional spirit practice education for medical students.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.
