Erectile dysfunction (ED) is prevalent among men, but its relationship with dietary habits is uncertain. The aim of our study was to assess whether dietary patterns enhance erectile function by reviewing the literature published before August 1, 2022, via PubMed, Web of Science, and EMBASE databases. The data compiled included author details; publication dates, countries, treatments, patient numbers, ages, follow-ups, and clinical trial outcomes, such as ED cases, odds ratios (ORs), confidence intervals (CIs), and International Index of Erectile Function-5 (IIEF-5) scores with means and standard deviations. An analysis of 14 studies with 27 389 participants revealed that plant-based diets (OR = 0.71, 95% CI: 0.66-0.75; P < 0.00001), low-fat diets (OR = 0.27, 95% CI: 0.13-0.53; P = 0.0002), and alternative diets such as intermittent fasting and organic diets (OR = 0.54, 95% CI: 0.36-0.80; P = 0.002) significantly reduced ED risk. High-protein low-fat diets (hazard ratio [HR] = 1.38, 95% CI: 1.12-1.64; P < 0.00001) and high-carb low-fat diets (HR = 0.79, 95% CI: 0.55-1.04; P < 0.00001) improved IIEF-5 scores. Combined diet and exercise interventions decreased the likelihood of ED (OR = 0.49, 95% CI: 0.28-0.85; P = 0.01) and increased the IIEF-5 score (OR = 3.40, 95% CI: 1.69-5.11; P < 0.0001). Diets abundant in fruits and vegetables (OR = 0.97, 95% CI: 0.96-0.98; P < 0.00001) and nuts (OR = 0.54, 95% CI: 0.37-0.80; P = 0.002) were also correlated with lower ED risk. Our meta-analysis underscores a strong dietary-ED association, suggesting that low-fat/Mediterranean diets rich in produce and nuts could benefit ED management.

Objective To quantify the association between obesity and erectile dysfunction (ED) risk through a meta-analysis. Methods Following PRISMA guidelines, systematic searches of Chinese and English databases (up to March 2025) were conducted to include observational studies (cohort, cross-sectional, case-control). Adjusted effect sizes (OR and 95% CI) were extracted. Study quality was assessed using the Agency for Healthcare Research and Quality(AHRQ) scale, and a random-effects model was applied to pool effect sizes. Subgroup analyses (geographic region, obesity definitions) and sensitivity analyses were performed to validate robustness. Results Ten studies (n=230 744), including nine cross-sectional studies, were included. The meta-analysis revealed that obesity significantly increased ED risk (random-effects OR=1.80, 95% CI: 1.29-2.51), with high heterogeneity (I2=99.9%). Subgroup analyses indicated stronger associations in USA populations (OR=2.10, 95% CI: 1.23-3.60) than in Chinese populations (OR=1.16, 95% CI: 1.05-1.28). The highest effect size was observed when using BMI≥25 kg/m3 as the obesity threshold (OR=3.05, 95% CI: 2.06-4.51). Sensitivity analyses confirmed robust results (OR: 1.60-1.94 after excluding any single study). Conclusions Obesity is a critical risk factor for ED, with effect strength influenced by geographic region and obesity definitions. Interventions targeting BMI≥30 kg/m2 in Western populations and metabolic risks at BMI≥25 kg/m3 in Asian populations are recommended.

ObjectiveTo explore the correlation between blood stasis constitution （BSC） and diseases based on constitution literature involving “constitution-diseases correlation”. MethodsA comprehensive search was conducted on six Chinese and English electronic databases including CNKI， Wanfang， VIP， SinoMed， PubMed and Embase to find all clinical researches on the correlation between constitution and diseases using the Classification and Identification of Chinese Medicine Constitution standard from April 1st， 2009 to December 31st， 2022， and the participants of the research were BSC related. By analyzing the characteristics of the literature， such as authors， publication institutes， participants， and results， the disease with the highest proportion of BSC distribution or BSC as their risk factors or protective factors were summarized to explore the correlation between BSC and diseases. ResultsTotally 135 clinical studies on diseases highly related to BSC were included， with a total sample size of 71 172 cases.There were 27 keywords in the articles appeared more than 3 times， including the elderly， lumbar disc herniation， coronary heart disease， cardiovascular disease， and endometriosis. In the author's clustering， included studis were mainly from Shenzhen Hospital of Beijing University of Chinese Medicine， Second Affiliated Hospital of Guangzhou University of Chinese Medicine， and Wenzhou Central Hospital. In terms of blood stasis related diseases， 81 studies showed that BSC was the most common type of constitution in the study population， involving 48 disease or morbid states. The diseases and median proportions of BSC with reported literature ≥3 included coronary heart disease （28.8%）， endometriosis （31.3%）， neurocognitive impairment （26.4%）， lumbar disc herniation （26.0%）， ischemic stroke （25.0%）， adenomyosis （34.7%）， and endometrial polyps （25.0%）. Fifty-eight studies found that BSC was a risk factor for disease occurrence，and these diseases reported more than 3 times included hypertension （median OR = 2.956）， type 2 diabetes （median OR = 3.436），osteoporosis （median OR = 5.171）， sudden deafness （median OR = 3.827） and endometriosis （median OR = 5.412）. One study indicated BSC as the protective factor of lateral growth tumor of large intestine （median OR = 0.161）. ConclusionBSC is closely related to circulatory system diseases， urogenital system diseases， and musculoskeletal system diseases.

PCOS is a highly prevalent disease in modern women of gestational age, characterized by infertility. Prevention before onset has been a key focus of national efforts in recent years. This article explored the prevention and treatment plan for polycystic ovary syndrome based on the three-level prevention theory of Academician Wang Qi. Primary prevention: control pathogenic risk factors; secondary prevention: precise screening and life intervention to prevent the formation of dangerous constitution; third level prevention: differentiation of body-differentiation of disease-differentiation of syndrome to achieve the goal of three-level prevention. In the prevention and treatment of PCOS, pre-disease prevention, post disease prevention and cure are tried to achieve, which could provide a truly effective, easy to operate, and applicable three-level prevention and treatment plan for a large population in clinical response to PCOS.

Objective:To explore the effect of sinomenine(SIN)on LPS-induced apoptosis and autophagy of lung epithelial cells through the JNK/c-Jun signaling pathway.Methods:MLE-12 lung epithelial cells were cultured,and the toxicity of SIN was detected by CCK-8.Apoptosis was detected by flow cytometry,the number of autophagosomes was detected by immunofluorescence,and the expression levels of apoptosis,autophagy and JNK/c-Jun signaling pathway-related proteins were detected by Western blot.Results:After LPS modeling,apoptosis rate and the number of autophagosomes were increased,the protein levels of Cleaved caspase-3,Bax,and Beclin-1,and LC3Ⅱ/LC3Ⅰ,p-JNK/JNK and p-c-Jun/c-Jun were increased(P<0.05);Bcl-2 and P62 protein levels were decreased(P<0.05).SIN treatment can significantly improve the effects of LPS on apoptosis and autophagy,as well as the regulation of the JNK/c-Jun signaling pathway(P<0.05).Treatment with the autophagy inhibitor 3-MA or the JNK agonist ANISO could partially reverse the protective effect of SIN on LPS-induced lung epithelial cells(P<0.05).Conclusion:SIN may increase autophagy and pro-tect lung epithelial cells damaged by LPS by regulating proteins related to the JNK/c-Jun signaling pathway.

Inducing the degradation of KRAS represents a novel strategy to combat cancers with KRAS mutation. In this study, we identify ubiquitin-specific protease 2 (USP2) as a novel deubiquitinating enzyme of KRAS in multiple myeloma (MM). Specifically, we demonstrate that gambogic acid (GA) forms a covalent bond with the cysteine 284 residue of USP2 through an allosteric pocket, inhibiting its deubiquitinating activity. Inactivation or knockdown of USP2 leads to the degradation of KRAS, resulting in the suppression of MM cell proliferation in vitro and in vivo. Conversely, overexpressing USP2 stabilizes KRAS and partially abrogates GA-induced apoptosis in MM cells. Furthermore, elevated USP2 levels may be associated with poorer prognoses in MM patients. These findings highlight the potential of the USP2/KRAS axis as a therapeutic target in MM, suggesting that strategically inducing KRAS degradation via USP2 inhibition could be a promising approach for treating cancers with KRAS mutations.

OBJECTIVE: To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients. METHODS: By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup. RESULTS: Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens. CONCLUSIONS There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.

Objective: To understand the current status of diagnosis and treatment of chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL) among hematologists, oncologists, and lymphoma physicians from hospitals of different levels in China. Methods: This multicenter questionnaire survey was conducted from March 2021 to July 2021 and included 1,000 eligible physicians. A combination of face-to-face interviews and online questionnaire surveys was used. A standardized questionnaire regarding the composition of patients treated for CLL/SLL, disease diagnosis and prognosis evaluation, concomitant diseases, organ function evaluation, treatment selection, and Bruton tyrosine kinase (BTK) inhibitor was used. Results: ①The interviewed physicians stated that the proportion of male patients treated for CLL/SLL is higher than that of females, and the age is mainly concentrated in 61-70 years old. ②Most of the interviewed physicians conducted tests, such as bone marrow biopsies and immunohistochemistry, for patient diagnosis, in addition to the blood test. ③Only 13.7% of the interviewed physicians fully grasped the initial treatment indications recommended by the existing guidelines. ④In terms of cognition of high-risk prognostic factors, physicians' knowledge of unmutated immunoglobulin heavy-chain variable and 11q- is far inferior to that of TP53 mutation and complex karyotype, which are two high-risk prognostic factors, and only 17.1% of the interviewed physicians fully mastered CLL International Prognostic Index scoring system. ⑤Among the first-line treatment strategy, BTK inhibitors are used for different types of patients, and physicians have formed a certain understanding that BTK inhibitors should be preferentially used in patients with high-risk factors and elderly patients, but the actual use of BTK inhibitors in different types of patients is not high (31.6%-46.0%). ⑥BTK inhibitors at a reduced dose in actual clinical treatment were used by 69.0% of the physicians, and 66.8% of the physicians had interrupted the BTK inhibitor for >12 days in actual clinical treatment. The use of BTK inhibitors is reduced or interrupted mainly because of adverse reactions, such as atrial fibrillation, severe bone marrow suppression, hemorrhage, and pulmonary infection, as well as patients' payment capacity and effective disease progression control. ⑦Some differences were found in the perceptions and behaviors of hematologists and oncologists regarding the prognostic assessment of CLL/SLL, the choice of treatment options, the clinical use of BTK inhibitors, etc. Conclusion: At present, a gap remains between the diagnosis and treatment of CLL/SLL among Chinese physicians compared with the recommendations in the guidelines regarding the diagnostic criteria, treatment indications, prognosis assessment, accompanying disease assessment, treatment strategy selection, and rational BTK inhibitor use, especially the proportion of dose reduction or BTK inhibitor discontinuation due to high adverse events.

OBJECTIVE: To analyze the composition, incidence and clinical characteristics of oral and maxillofacial infections in oral emergency. METHODS: A retrospective study on patients with oral and maxillofacial infections who visited the Department of Oral Emergency in Peking University School and Hospital of Stomatology from January 2017 to December 2019 was conducted. General characteristics, such as disease composition, gender, age distribution and position of involved teeth were analyzed. RESULTS: A total of 8 277 patients with oral and maxillofacial infections were finally collected, including 4 378 male patients (52.9%) and 3 899 female patients (47.1%), with gender ratio of 1.12:1. The common diseases were periodontal abscess (3 826 cases, 46.2%), alveolar abscess (3 537 cases, 42.7%), maxillofacial space infection (740 cases, 9.0%), sialadenitis (108 cases, 1.3%), furuncle & carbuncle (56 cases, 0.7%) and osteomyelitis (10 cases, 0.1%). Male patients were more easily affected by periodontal abscess, space infection and furuncle & carbuncle than female patients with the gender ratios 1.24:1, 1.26:1, 2.50:1 individually, while the incidence of alveolar abscess, sialadenitis, furuncle & carbuncle had no significant gender difference. Different diseases were prone to occur at different ages. The peak ages of alveolar abscess were 5-9 and 27-67 years, while the peak age of periodontal abscess was 30-64 years. Space infection tended to occur between 21-67 years. There were 7 363 patients with oral abscess (3 826 patients with periodontal abscess and 3 537 patients with alveolar abscess), accounting for 88.9% of all the patients with oral and maxillofacial infections, involving 7 999 teeth, including 717 deciduous teeth and 7 282 permanent teeth. Periodontal abscess usually occurred in permanent teeth, especially the molar teeth. Alveolar abscess may occur in both primary teeth and permanent teeth. In primary teeth, the most vulnerable sites were primary molar teeth and maxillary central incisors while in permanent teeth the most vulnerable sites were first molar teeth. CONCLUSION Understanding the incidence of oral and maxillofacial infection was conducive to the correct diagnosis and effective treatment of clinical diseases, as well as targeted education for patients of different ages and genders to prevent the occurrence of diseases.
