Objective:Investigating the efficacy of unilateral adrenalectomy in treatment for primary pigmented nodular adrenocortical disease (PPNAD).Methods:Clinical data of 26 patients with PPNAD treated in our hospital from January 2013 to June 2023 was retrospectively analyzed.There were 11 males and 15 females, with an average age of (19.4±4.7) years. 25 cases presented with typical Cushing's syndrome, and 16 cases were diagnosed with Carney's syndrome. PRKAR1A gene mutation detected in 8 out of 10 cases. CT showed multiple small nodules on bilateral adrenal glands in 14 cases, unilateral small nodules or mild thickening with normal contralateral glands in 8 cases, and no obvious abnormalities in 4 cases. All patients showed autonomous oversecretion of cortisol by endocrine laboratory tests, with a median 24 h-UFC of 408.35 (334.28, 800.78) μg/24 h and decreased level of adrenocorticotropic hormone. All 26 patients underwent laparoscopic unilateral adrenalectomy, with left side adrenalectomy in 8 cases and right side adrenalectomy in 18 cases.Results:The average surgical duration was (85.2±28.7) minutes, with intraoperative blood loss <50 ml in all cases. The median time to drainage tube removal post-operation was 3 (2, 3) days. One patient developed a postoperative pulmonary infection, and 3 patients required postoperative hormone replacement therapy. The median follow-up duration was 64 (31.5, 103.8) months, and all patients showed alleviation of Cushing syndrome clinical manifestations after operations. 19 patients (73.1%) had their 24 h-UFC levels normalized to a median of 42.0 (22.4, 58.3) μg/24 h within 8.5 (5, 46) days post-surgery. 7 patients (26.9%) did not achieve normal 24 h-UFC levels, yet experienced an average reduction of (73.2±10.4)%. 13 patients (50.0%) did not experience recurrence, with a median follow-up of 51 (7, 89.5) months, including two cases without recurrence at 10 years post-surgery. 13 patients showed recurrent increase in postoperative cortisol levels, with a median of 225.6 (188.9, 397.2) μg/24 h. The median time to increased 24 h-UFC post-surgery was 27 (13.5, 50.5) months, with the longest duration reaching 104 months. Among these, 9 cases exhibited clinical signs and symptoms of recurrence, while 4 cases did not. Of the 13 patients with recurrence, 9 underwent contralateral adrenalectomy or subtotal resection, while 4 were observed with follow-up.Conclusions:Unilateral adrenalectomy could be a surgical treatment option for PPNAD. Despite the recurrence in some patients postoperatively, unilateral adrenalectomy could effectively and rapidly reduce cortisol levels in PPNAD patients and alleviate the clinical manifestations of Cushing syndrome.

Tuberous sclerosis complex(TSC)is a rare genetic disease that can lead to benign dysplasia in multiple organs such as the skin, brain, eyes, oral cavity, heart, lungs, kidneys, liver, and bones. Its main symptoms include epilepsy, intellectual disabilities, skin depigmentation, and facial angiofibromas, whilst incidence is approximately 1 in 10 000 to 1 in 6000 newborns. This case presents a middle-aged woman who initially manifested with epilepsy and nodular depigmentation. Later, she developed a lower abdominal mass, elevated creatinine, and severe anemia. Based on clinical features and whole exome sequencing, the primary diagnosis was confirmed as TSC. Laboratory and imaging examinations revealed that the lower abdominal mass originated from the uterus. CT-guided biopsy pathology and surgical pathology suggested a combination of leiomyoma and abscess. With the involvement of multiple organs and various complications beyond the main diagnosis, the diagnostic and therapeutic process for this patient highlights the importance of rigorous clinical thinking and multidisciplinary collaboration in the diagnosis and treatment of rare and challenging diseases.

Objective To explore the clinical and imaging features of phosphaturic mesenchymal tumor(PMT).Methods The clinical presentations,laboratory examinations,and imaging manifestations of seven patients with PMT diagnosed by surgery and pathology were analyzed retrospectively.Results Among the 7 patients,four patients had clinical presentations of long-term fatigue and bone pain.All patients showed preoperative blood phosphorus reduction in varying degrees.X-ray examination showed systemic osteomalacia and osteoporosis,accompanied by multiple pathological fractures.On CT,the primary tumor appeared as a soft tissue density mass or a ground glass high-density nodule with irregular calcification and local bone destruction.MRI showed long T1,long T2 signal intensity,and irregular low signal foci were scattered in the T2WI fat-suppressed sequence.The enhanced scans showed moderate to significant inhomogeneous enhancement.One patient who underwent 18F-FDG PET/CT and two patients who underwent 18F-ALF-NOTA-Octreotide(18F-OC)PET/CT examinations showed varying degrees of radioactive concentration in the lesions.Conclusion The clinical presentations and laboratory examinations of patients with PMT have certain characteristics.Systemic osteomalacia with pseudofracture line,calcification matrix within the tumor,and significant inhomogeneous enhancement of the lesion are the key imaging features for diagnosing PMT.18F-OC PET/CT examination plays a crucial role in the systemic localization diagnosis of tumors.

OBJECTIVES: We aimed to quantify the temporal associations between cervical cancer incidence and cervical cancer-related factors and to predict the number of new cervical cancer cases averted under counterfactual scenarios compared to the status quo scenario. METHODS: We described temporal trends in cervical cancer and associated factors globally from 1990 to 2019. We then used generalized linear mixed models to explore the impact of tobacco use, sexually transmitted infections (STIs), human papillomavirus (HPV) vaccination, and cervical screening on cervical cancer incidence. A counterfactual analysis was performed to simulate the most effective scenario for reducing cervical cancer incidence. RESULTS: The worldwide incidence of cervical cancer showed a downward trend over the past 3 decades (estimated annual percentage change, -0.72%), although the incidence remained high (>30 cases per 100,000 persons) in sub-Saharan Africa, Latin America, and the Caribbean. Higher smoking and STI prevalence showed significant direct associations with the incidence of cervical cancer, whereas HPV vaccination and screening coverage showed significant inverse associations. If the strategic goals for accelerating the elimination of cervical cancer and tobacco control programs had been achieved in 2019, the largest decrease in the number of new cervical cancer cases would have been observed, with 54,169 fewer new cases of cervical cancer in 2019. CONCLUSIONS Our counterfactual analysis found that a comprehensive intervention program emphasizing scaled-up cervical screening coverage (70%), HPV vaccination coverage (90%), and tobacco control (30% relative reduction) would be the most effective program for reducing cervical cancer incidence.

Objective:To explore the clinical value of 68Ga-pentixafor PET/CT targeting for CXCR4 in the diagnosis and prognosis evaluation of primary aldosteronism (PA). Methods:Retrospective analysis was performed on information of 72 patients diagnosed with PA who received operations according to the results of 68Ga-pentixafor PET/CT in our hospital. There were 37 males and 35 females, with the average age of (48.3±9.5) years old. The average lesion diameter was (1.60 ± 0.54)cm. The preoperative systolic and diastolic blood pressure were (177.3 ± 23.9)mmHg and (107.6 ± 13.2)mmHg, respectively. The average preoperative potassium level was (2.62 ± 0.56)mmol/L. The average aldosterone concentration was (17.98 ± 4.66)ng/dl, and the median plasma renin activity was 0.01 (0.01, 0.09) ng/(ml·h). All patients underwent 68Ga-pentixafor PET/CT examination, which lead to the decision of surgical strategies. For those patients with single lesion, multiple lesions in one side or positive lesion in one side but negative in the opposite side, surgical resection of the positive side lesion or total adrenalectomy was considered. For those patients with bilateral positive lesions, surgical resection of the side with more significant positive lesions or total adrenalectomy was considered. For those with negative multiple lesions, the surgical strategy was designed according to the results of CT examination or AVS. The positive rate of 68Ga-pentixafor PET/CT and its relationship with the clinical characteristics and prognosis of patients were analyzed. Results:The results of 68Ga-pentixafor PET/CT were positive in 62 of 72 patients diagnosed with PA (86.1%), and the median SUVmax value was 11.1 (7.1, 16.2). The SUVmax value was positively correlated with the maximum diameter of adrenal lesion ( r=0.468) and negatively correlated with blood potassium levels ( r=-0.437), while not significantly correlated with other clinical characteristics. The positive rate of adenoma by 68Ga-pentixafor PET/CT was higher than that of nodular hyperplasia [90.5%(57/63) vs. 55.6%(5/9), P=0.018], and the SUVmax value in adenoma was also higher than that in nodular hyperplasia [11.9(7.8, 16.2) vs. 4.3(3.4, 11.3), P=0.022]. 32 cases were cured after operations, and 37 cases were improved. And 3 cases were not cured. The SUVmax value of lesions in the cured patients was higher than that in the improved patients [15.4(8.1, 22.7) vs. 10.1(6.8, 13.3), P=0.013]. Among 59 cases of PA patients with single adrenal lesions, 50 cases represented positive results of 68Ga-pentixafor PET/CT. 23 cases in 50 positive cases were cured and 27 cases were improved after resection of positive lesions. In the 13 PA patients with multiple adrenal lesions who underwent surgery according to the results of 68Ga-pentixafor PET/CT, 12 patients (92.3%) showed postoperative prognosis in line with preoperative expectations. Conclusions:68Ga-pentixafor PET/CT showed high positive rate in the diagnosis of PA, especially for adenoma.The SUVmax value of the adrenal lesion was correlated with the blood potassium level, the size of the lesion and the postoperative prognosis. In addition, 68Ga-pentixafor PET/CT could effectively guide the surgical decision of PA.

Objective:To comprehensively analyze the expression profile of circular RNA (circRNA) and construct competing endogenous RNA (ceRNA) regulatory networks in tuberous sclerosis complex related renal angiomyolipoma (TSC-RAML).Methods:According to the diagnostic criteria of TSC determined by the international consensus group on tuberous sclerosis in 2012, tumor tissues and paired normal renal tissues of 3 patients with TSC-RAML who were diagnosed in our hospital from January 2017 to January 2019 were collected. The circRNA, miRNA and mRNA of 3 paired samples were detected by circRNA, miRNA chip technology and next generation sequencing respectively, and the differential molecules were determined. Gene Ontology(GO) functional enrichment analysis and Kyoto Encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed based on differential mRNA molecules and host genes of circRNA. Based on differential circRNA, miRNA and mRNA, up-regulated and down-regulated ceRNA regulatory networks were established.Results:A total of 330 up-regulated and 336 down-regulated differential circRNA, 8 up-regulated and 7 down-regulated miRNA, 800 up-regulated and 1130 down-regulated mRNA were screened. Through GO and KEGG enrichment analysis, many pathways including lipid metabolism, focal adhesion and mineral absorption were abnormally altered. Finally, the up-regualted ceRNA network led by hsa_circ_0092022, hsa_circ_0076859 and hsa_circ_0033388 and down-regulated network led by hsa_circ_0000374, hsa_circ_0000141, hsa_circ_0072665, hsa_circ_0009503 and hsa_circ_0000009 were constructed.Conclusions:There were many differentially expressed circRNA between TSC-RAML and paired normal renal tissues. ceRNA regulatory networks may be involved in the occurrence and development of TSC-RAML.

Objective:To observe the clinical characteristics of esophageal reflux after total gastrectomy (ERATG), and to explore the mechanism of occurrence.Methods:Fourteen gastric cancer patients who underwent total gastrectomy were prospectively enrolled in this study. The postoperative symptoms were observed and recorded and 24 h MII-pH with pH monitoring was performed to investigate the characteristics of postoperative reflux.Results:After total gastrectomy patients were with different degrees of ERATG as heartburn, appetite loss, chest tightness and belching. The overall nature of ERATG is mainly weak acid, with a pH between 4 and 7. ERATG involved esophageal-jejunal anastomosis and a length of esophagus 7 cm above the anastomosis. Patients with typical reflux symptoms had a lower pH minimum in the upright position than those without typical symptoms[(4.76±0.71) vs.(5.68±0.37), t=2.866, P<0.05]. Patients with typical reflux symptoms had a higher frequency of reflux of mixed liquid and liquid-air reflux than those without typical symptoms[liquid(31.25±29.76) vs.(4.50±9.14), t=0.011, P<0.05; liquid-air(19.50±12.99) vs.(2.00±2.61), t=0.004, P<0.05]. Conclusion:ERATG is mainly a upward reflux of weakly acidic gas, with typical symptoms of heartburn, appetite loss, chest tightness and belching. Patients with typical symptoms usually have lower pH in the upright position.

Objective:To invetigate the influencing factors and clinical significance of liver function damage (LFD) in patients diagnosed with Corona Virus Disease 2019 (COVID-19).Methods:The retrospective case-control study was conducted. The clinicopathological data of 51 patients with COVID-19 who were admitted to the Sino-French New City Branch of Tongji Hospital Affiliated to Huazhong University of Science and Technology by the 5th group assisting team from the First Hospital of Jilin University from February 9th to 27th in 2020 were collected. There were 27 males and 24 females, aged from 36 to 86 years, with an average age of 68 years. The treatment modality was according to the diagnostic and therapeutic guideline for COVID-19 (Trial 6th edition) issued by National Health Commission. Observation indicators: (1) clinical data of patients; (2) analysis of liver function index and treatment of LFD; (3) analysis of influencing factors for LFD. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were described as M (range). Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. The Logistic regression method was used for univariate analysis. Results:(1) Clinical data of patients: of the 51 patients, 21 were classified as ordinary type of COVID-19, 19 as severe type and 11 as critical type. In terms of medical history, 31 patients suffered from more than or equal to one kind of chronic disease, 20 had no history of chronic disease. Thirteen patients had the drinking history and 38 had no drinking history. Seven patients were hepatitis positive and 44 were hepatitis negative. Five patients had septic shock at admission, 5 had systemic inflammatory response syndrome (SIRS), and 41 had neither shock nor SIRS. The body mass index (BMI), time from onset to admission, temperature, heart rate, respiratory rate of the 51 patients were (24±3)kg/m 2, (13±5)days, 36.5 ℃ (range, 36.0-38.1 ℃), 82 times/minutes (range, 50-133 times/minutes), 20 times/minutes (range, 12-40 times/minutes). The white blood cell count, level of creatinine, and level of b-type natriuretic peptide within 24 hours after admission were 6.3×10 9/L [range, (2.2-21.7)×10 9/L], 75 μmol/L (range, 44-342 μmol/L), 214 ng/L (range, 5-32 407 ng/L). (2) Analysis of liver function index and treatment of LFD: the level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), direct bilirubin (DBil), indirect bilirubin (IBil), activated partial thromboplastin time (APTT) and prothrombin time (PT) were 31 U/L (range, 7-421 U/L), 29 U/L (range, 15-783 U/L), 36 U/L (range, 13-936 U/L), 76 U/L (range, 41-321 U/L), 4.9 μmol/L (range, 2.6-14.3 μmol/L), 5.8 μmol/L (range, 2.6-23.9 μmol/L), 37.2 s (range, 30.9-77.1 s), 13.9 s (range, 12.5-26.7 s), respectively. The percentages of cases with abnormal ALT, AST, GGT, ALP, DBil, IBil, APTT and PT were 47.1%(24/51), 47.1%(24/51), 35.3%(18/51), 13.7%(7/51), 7.8%(4/51), 2.0%(1/51), 21.6%(11/51), and 19.6%(10/51), respectively. Of the 51 patients, LFD was detected in 10 patients classified as ordinary type, in 9 patients as severe type, and in 10 as critical type, respectively. In the 51 patients, 1 of 22 patients with normal liver function developed respiratory failure and received mechanical ventilation within 24 hours after admission, while 9 of 29 patients with abnormal liver function developed respiratory failure and received mechanical ventilation, showing a significant difference between the two groups ( χ2=5.57, P<0.05). (3) Analysis of influencing factors for LFD. Results of univariate analysis showed that clinical classification of COVID-19 as critical type was a related factor for LFD of patients ( odds ratio=10.000, 95% confidence interval: 1.050-95.231, P<0.05). Conclusions:COVID-19 patients with LFD are more susceptible to develop respiratory failure. The clinical classification of COVID-19 as critical type is a related factor for LFD of patients.

Objective:To determine the diagnostic value of tumor markers in peritoneal lavage fluid from colorectal cancer patients for tumor peritoneal metastasis.Methods:A total of 227 colorectal cancer patients who undergoing surgical treatment were included. 300 ml of peritoneal lavage fluid was irrigated immediately upon laparotomy for traditional cytology (PLC) testing, 134 patients were tested for tumor marker of peritoneal lavage fluid (pTM). Univariate analysis was performed to determine the risk factors for peritoneal metastasis; pTM ROC curve was used to determine the best cutoff value; paired chi-square test was used to compare the difference between PLC and pTM detection.Results:The positive rate of PLC was 12.3% (28/227). Age>65, stage T3 + , lymph node metastasis, mucinous adenocarcinoma and increased serum CA125, CA19-9 are related to peritoneal metastasis; The best cutoff value of pTM for peritoneal metastasis : pCEA 17.095 ng/dl, sensitivity 58.3%, specificity 93.9%; pCA19-9 4.515 U/ml, sensitivity 83.3%, specificity 80.0%; pCA125 303.2 U/ml, sensitivity 58.3%, specificity 95.7%; pCA-724 3.01 U/ml, sensitivity 66.7%, specificity 95.7%; The best cutoff value of pTM for peritoneal micrometastasis: pCA19-9 3.43 U/ml, sensitivity 100%, specificity 72.2%. The positive rate of pCA19-9 was 29.85%, which was higher than that of PLC (χ 2=2.00, P<0.05). Conclusion:Peritoneal metastasis of colorectal cancer is related to tumor T stage, lymph node metastasis, tumor pathological type, and increased serum CA125 and CA19-9; pTM has diagnostic value for peritoneal metastasis of colorectal cancer.

We report a case of chromoblastomycosis caused by , which was successfully treated by long-pulsed 1064 nm Nd: YAG laser combined with terbinafine. A 60-year-old man was admitted for the presence of a 30 mm×40 mm erythematous plaque on the dorsum of his right hand for about 10 months without any subjective symptoms. Both microscopic examination and tissue biopsy of the lesion showed characteristic sclerotic bodies of chromoblastomycosis. Lesion tissue culture on SDA at 26 ℃ for 2 weeks resulted in a black colony, and slide culture identified the isolate as Fonsecaea species. ITS sequence analysis of the isolate showed a 99% homology with strain KX078407. The susceptibility of the isolate to 9 antifungal agents was determined using the microdilution method according to the guidelines of CLSI M38-A2 protocol, and terbinafine showed the lowest MIC (0.125 μg/ml). We subsequently established a Wistar rat model of chromoblastomycosis using the clinical isolate and treated the rats with long-pulsed 1064 nm Nd: YAG laser (pulse width of 3.0 ms, fluence of 24 J/cm, spot size of 3 mm, frequency of 4 Hz, repeated 3 times at an interval of 30 s) twice a week for a total of 8 sessions. Although the laser treatment alone was not able to eliminate the fungi, histopathological examination showed the aggregation of numerous lymphocytes in the local affected tissue, indicating an immune response that consequently facilitate the regression of the lesion. The patient was successfully treated by long-pulsed 1064 nm Nd: YAG laser once a week combined with terbinafine (0.25 /bid) for 8 weeks, and follow-up for 20 months did not reveal any signs of recurrence.
