A previous study showed that the length of the foreskin plays a role in the risk of sexually transmitted infections and chronic prostatitis, which can lead to poor quality of sexual life. Here, the association between foreskin length and sexual dysfunction was evaluated. A total of 5700 participants were recruited from the andrology clinic at The First Affiliated Hospital of University of Science and Technology of China (Hefei, China). Clinical characteristics, including foreskin length, were collected, and sexual function was assessed by the International Index of Erectile Function-5 (IIEF-5) and Premature Ejaculation Diagnostic Tool (PEDT) questionnaires. Men with sexual dysfunction were more likely to have redundant foreskin than men without sexual dysfunction. Among the 2721 erectile dysfunction (ED) patients and 1064 premature ejaculation (PE) patients, 301 (11.1%) ED patients and 135 (12.7%) PE patients had redundant foreskin, respectively. Men in the PE group were more likely to have redundant foreskin than men in the non-PE group ( P = 0.004). Logistic regression analyses revealed that the presence of redundant foreskin was associated with increased odds of moderate/severe ED (adjusted odds ratio [aOR] = 1.31, adjusted P = 0.04), moderate PE (aOR = 1.38, adjusted P = 0.02), and probable PE (aOR = 1.37, adjusted P = 0.03) after adjusting for confounding variables. Our study revealed a positive correlation between the presence of redundant foreskin and the risk of sexual dysfunction, especially in PE patients. Assessment of the length of the foreskin during routine clinical diagnosis may provide information for patients with sexual dysfunction.

OBJECTIVE: To screen the genetic risk factors related to severe hematology adverse effects (AEs) in patients with chronic myeloid leukemia (CML) treated with imatinib (IM), and explore the correlation of single nucleotide polymorphisms (SNPs) in IM drug metabolism and transport pathway gene polymorphism with the risk of severe hematology AEs. METHODS: 172 newly diagnosed Chinese Han patients in CML chronic phase (CML-CP) treated with IM were included and divided into severe hematology AEs group and non-severe hematology AEs group. The demographic characteristics and laboratory test results were compared between the two groups. 11 gene SNP sites in the included subjects were genotyped using SNaPshot multiplex SNPs technique. RESULTS: Compared with non-severe hematology AEs group, the severe hematology AEs group had higher white blood cell (WBC) and EOS% (both P < 0.05), but lower hemoglobin (Hb) and hematocrit (HCT) (both P < 0.01). For rs1045642 of ABCB1 gene, there were significant differences in the distribution of allele frequency and genotype frequency of this loci between severe hematology AEs group and non-severe hematology AEs group (both P < 0.05). Carriers of rs1045642 mutation allele A had an increased risk of severe hematology AEs (OR =2.09, 95% CI : 1.24-3.55, P =0.005). There was a significant difference in the distribution of NR1I2 gene rs3814055 genotype between severe hematology AEs group and non-severe hematology AEs group (P < 0.05). The additive model and recessive model of ABCB1 gene rs1045642 and the recessive model of NR1I2 gene rs3814055 were associated with the increased risk of severe hematology AEs (OR =2.14, 3.28, 5.54, all P < 0.05). CONCLUSION Peripheral blood WBC, EOS%, Hb and HCT in patients with newly diagnosed CML-CP are all related to the risk of severe hematology AEs. ABCB1 gene rs1045642 and NR1I2 gene rs3814055 related to the metabolism and transport pathway of IM are associated with severe hematology AEs after IM treatment in CML-CP patients, and they may be potential molecular markers to predict the risk of severe hematology AEs of CML patients treated by IM.

The thought of medicine and food homology and substances with both edible and medicinal values are an important part of China's excellent traditional culture and medicine treasure, playing an important role in human diet and health maintenance for thousands of years. Substances with both edible and medicinal values are a standardized name governed by existing regulations, and many substances with both edible and medicinal values in the list lack important information such as original plants and edible and medicinal parts. Some substances change as the relevant regulations change, which confuses the use and regulation. According to the definition and inclusion conditions of substances with both edible and medicinal values in the Regulation of Substances with Both Edible and Medicinal Values Catalogue, this paper comprehensively reviewed the first batch of 87 substances with both edible and medicinal values published in 2002 by collecting information and investigating the practical application. Some substances supplemented, deleted, and revised were analyzed and discussed, and a complete revised list was compiled, encompassing a total of 90 substances, which were when combined with the 19 substances of the last three batches(published in 2019, 2023, and 2024), amounted to a total of 109 substances. In addition, the substances not currently in the published list but have both edible and medicinal values according to the latest definition were summarized, which revealed at least 27 other substances. Therefore, there were at least 136 substances with both edible and medicinal values. Additionally, the potential substances that could be included in the list of substances with edible and medicinal values were prospected, providing a focus for future expansion of the list. This paper systematically reviewed and revised the list of substances with both edible and medicinal values to lay a foundation for the regulatory authorities to revise the catalog of these substances and provide basic information for promoting the new quality productive forces in the health field and boosting the orderly and rapid development of the big health industry.

Objective:To evaluate the clinical efficacy of endoscopic treatment of superficial non-ampullary duodenal adenoma.Methods:A retrospective analysis was performed on the clinical data and follow-up information of patients diagnosed with superficial duodenal non-ampullary adenomas via preoperative endoscopy and treated endoscopically at Peking University First Hospital between January 2013 and January 2024. The overall en bloc resection rate, complete resection rate of the lesion, perioperative complications, and recurrence rates were evaluated. Patients were categorized into three groups based on their treatment modality: endoscopic mucosal resection (EMR)（ n=46）, endoscopic submucosal dissection (ESD)（ n=16）, and modified ESD (ESD with snare, ESD-S)（ n=24）. Comparative analyses were conducted to evaluate operative time, en bloc resection rate, and complete resection rate among the three groups. Results:Among 86 patients, the overall en bloc and complete resection rates were 87.2% (75/86) and 86.0% (74/86), respectively. No case of delayed bleeding was observed during the perioperative period. Intraoperative perforation occurred in two patients, both of whom improved following conservative management. Delayed perforation was noted in four patients, and three of them were successfully managed with surgical intervention, while one case was resolved after conservative treatment. During the follow-up period, local recurrence was identified in two patients. Following re-treatment with endoscopy and continuous surveillance, no further recurrence was observed. The operative times for the EMR group, ESD-S group, and ESD group were 4 (1-36) minutes, 25 (5-190) minutes, and 46 (5-150) minutes, respectively. Significant differences were observed in operative times among the three groups ( Hc=49.892, P<0.001). The en bloc resection rates for the EMR, ESD-S, and ESD groups were 80.4% (37/46), 91.7% (22/24), and 100.0% (16/16), respectively. The complete resection rates were 80.4% (37/46), 91.7% (22/24), and 93.8% (15/16) for the respective groups. Conclusion:Endoscopic treatment demonstrates favorable efficacy and safety for superficial non-ampullary duodenal adenoma. In addition to traditional EMR and ESD, ESD-S is also an effective procedure for endoscopic treatment of non-ampullary duodenal adenoma.

Objective:To compare the efficacy of polyethylene glycol (PEG) electrolyte powder versus oral sulfate solution (OSS) for bowel preparation and their impacts on colonoscopy quality.Methods:This single-center, retrospective, cross-sectional study included patients who underwent colonoscopy with PEG or OSS at Endoscopy Center, central branch of Peking University First Hospital between January 1 st and December 31 st 2024. Indicators including bowel cleanliness score, adenoma detection rate (ADR), sessile serrated lesion detection rate (SSLDR) were analyzed, and age-stratified subgroup analysis were performed. Binary logistic regression analysis was performed to identify factors associated with excellent bowel cleanliness. The quality of colonoscopy under two bowel preparation regimens were evaluated. Results:A total of 15 936 patients with 13 321 in the PEG group and 2 615 in the OSS group were included. The PEG group had higher overall Boston bowel preparation scale score [8.00 (7.00, 8.00) VS 8.00 (6.00, 8.00), Z=-5.560, P<0.001], especially in the transverse and descending colon, and higher foam scores in the descending colon ( Z=-2.589, P=0.010). Use of PEG, female gender, afternoon examination, and younger age positively predicted excellent cleanliness. ADR [44.8% (5 965/13 321) VS 39.2% (1 024/2 615), P<0.001] and SSLDR [7.8% (1 035/13 321) VS 6.0% (157/2 615), P=0.002] were higher in the PEG group than those in the OSS group. Age stratification confirmed PEG's superiority in both >50 and ≤50 age groups, with ADRs of 54.0% (4 808/8 910) and 31.0% (2 181/7 026), respectively, and SSLDRs of 8.1% (721/8 910) and 6.7% (471/7 026), respectively. For those >50 years old, the PEG group detected more elevated polyps. Conclusion:While both regimens provide adequate bowel preparation, PEG regimen demonstrates superior cleansing quality, ADR, SSLDR, over OSS regimen, particularly in patients over 50 years old, and those with higher risk polyps.

The bidirectional communication between gut microbiome and host significantly affects brain function,and there is increasing evidence that the imbalance of gut microbiota is closely related to the onset of Alzheimer's disease(AD).Blood-and gut-based metabolites,such as trimethylamine oxide,short-chain fatty acids,GABA and tryptophan metabolites,are likely to be the main mediators of the"microbiota-gut-brain axis",and play an important role in maintaining intestinal flora homeostasis and intestinal mucosal integrity,regulating the host immune system and cognitive function.This paper aims to summarize the blood and intestinal metabolites in the development of AD disease,and provide a new direction for the treatment of AD in the future.
