Lung cancer is one of the most lethal cancers, and the overall survival rate of lung cancer patients is very low. With the increasing research on lung cancer, the critical role of intestinal flora in lung cancer treatment has been gradually discovered. Among the various therapeutic approaches targeting the intestinal flora, fecal microbiota transplantation (FMT) is considered as a potential strategy to treat lung cancer by interfering with the homeostasis of the intestinal flora. FMT can improve the efficacy of lung cancer treatment and attenuate the side effects associated with immunotherapy, chemotherapy, and radiotherapy by remodeling the microbial composition, modulating the metabolites, and activating immune responses. The aim of this paper is to discuss the current status and potential mechanisms of FMT in lung cancer treatment, and to provide a new strategy for regulating the intestinal flora to enhance the prevention and treatment of lung cancer.

Diamond-Blackfan anemia(DBA),also known as congenital pure red cell aplasia,is a rare genetic disorder characterized by bone marrow failure,congenital anomalies,and severe red blood cell abnormalities.The rarity of the condition,and consequently limited patient pool and scarcity of research models,means that the pathogenic mechanisms associated with genetic mutations in DBA remain uncertain,and the clinical treatment options are limited.This review synthesizes the findings from zebrafish,mouse,and human cellular models of DBA mutations.We clarify the pathogenic mechanisms and monitor the progression of drugs into clinical trials,thereby aiding further in-depth explorations into the etiology and therapeutic advancements for DBA.

Objective:To compare the efficacy and safety of cold-endoscopic mucosal resection (C-EMR) and hot-endoscopic mucosal resection (H-EMR) for the treatment of colorectal polyps sized 10-20mm.Methods:Patients who underwent colonoscopy at the Gastrointestinal Endoscopy Center of the Eighth Affiliated Hospital, Sun Yat-sen University from January 2022 to January 2023 were selected as the research subjects. Patients meeting the inclusion criteria with at least one 10-20 mm, Paris type Ⅰs, type Ⅱa polyp were selected. They were divided into C-EMR group (no high-frequency current treatment) and H-EMR group (high-frequency electrical polyp removal) based on the random number table method. The main outcome measures were the complete resection rate of polyps, the incidence of postoperative complications (bleeding, perforation and infection), and the recurrence rate of polyps in the two groups. Secondary outcomes were the procedure time and cost-effectiveness.Results:A total of 209 eligible polyps were found in 209 patients, 105 in the C-EMR group (105 patients) and 104 in the H-EMR group (104 patients). There was no significant difference in the complete removal rate of polyps [91.4% (96/105) VS 95.2% (99/104), χ2=1.184, P=0.276], the recurrence rate of polyps [2.9% (3/105) VS 1.9% (2/104), χ2=0.195, P=0.683] or the incidence of complications [5.7% (6/105) VS 1.9% (2/104), χ2=2.040, P=0.280] between the C-EMR group and the H-EMR group. Compared with H-EMR group, the operation time of C-EMR group was shorter (5.26±2.41 min VS 9.34±5.63 min, t=-8.478, P<0.001), and the number of titanium clips used was fewer (2.55±0.94 VS 3.94±1.14, t=-9.623, P<0.001), and the differences between the two groups were statistically significant. The cost of polypectomy was lower in the C-EMR group than that in the H-EMR group (2 720±452 yuan VS 3 031±293 yuan), but the difference was not stastistically significant（ t=-5.896， P=0.651）. Conclusion:C-EMR demonstrates non-inferior efficacy and safety in treating 10-20 mm colorectal polyps compared with H-EMR. Widespread adoption of C-EMR may lead to reduced healthcare costs and expenditures.

BACKGROUND:Observational studies have suggested that statin drugs may have a protective effect on bone density,making them a potential treatment option for osteoporosis. OBJECTIVE:To evaluate the causal relationship between drug target-mediated lipid phenotypes and bone mineral density(BMD)using Mendelian randomization methods. METHODS:We obtained single nucleotide polymorphismsrelated to statin drugs and BMD data from the IEU Open GWAS database.The primary analysis method was the inverse variance weighted method,and we also used weighted median,simple median,weighted mode,and MR-Egger regression.We usedβ values and 95%confidence intervals(CI)to assess the causal relationship between statin drugs and BMD.Additionally,we conducted sensitivity analyses to validate the results,assessed heterogeneity using Cochran's Q test,examined for horizontal pleiotropy using the MR-Egger intercept test,and performed leave-one-out analyses to determine if individual or multiplesingle nucleotide polymorphism influenced the results. RESULTS AND CONCLUSION:There was a significant association between the statin target of action,3-hydroxy-3-methyl glutaryl coenzyme A reductase-mediated low-density lipoprotein cholesterol,and heel bone BMD(β=-0.086,95%CI:-0.117 to-0.055,P=5.42×10-8)and whole-body BMD(β=-0.193,95%CI:-0.288 to-0.098,P=7.35×10-5).The findings of this study support the protective effect of statin drugs on BMD.These findings not only deepen our understanding of the relationship between cholesterol-related genes and bone health but also reveal potential therapeutic targets for improving BMD.

BACKGROUND:Epidemiologic studies have shown a correlation between type 2 diabetes mellitus and bone mineral density,but the causal association between the two and whether it is age-related remains unknown. OBJECTIVE:To study the correlation between type 2 diabetes mellitus and whole body bone mineral density at unspecified age and at all ages based on the Mendelian randomization technique. METHODS:The genome-wide association study(GWAS)data of type 2 diabetes mellitus and bone mineral density at all ages were selected from the IEU GWAS database of the University of Bristol.The exposure data were single nucleotide polymorphisms with significant correlation with type 2 diabetes mellitus as instrumental variables,and bone mineral density at all ages was selected as the outcome variable.Two-sample Mendelian randomization analysis of type 2 diabetes mellitus and bone mineral density was performed using inverse variance weighted method,weighted median estimator,and MR-Egger regression.The βvalue was used to evaluate the causal relationship between type 2 diabetes mellitus and bone mineral density at all ages. RESULTS AND CONCLUSION:A total of 118 single nucleotide polymorphisms were extracted from the GWAS summary data as instrumental variables.The MR-Egger regression results showed that there was no horizontal pleiotropy,but there was heterogeneity.Therefore,this study was based on the inverse variance weighted results.Inverse variance weighted results showed that type 2 diabetes mellitus may be a potential protective factor for bone mineral density and is associated with age:age-unspecified bone mineral density[β=0.038,95%confidence interval(CI):1.01-1.07,P=0.002],bone mineral density over 60 years old(β=0.052,95%CI:1.01-1.09,P=0.027),bone mineral density between 45-60 years old(β=0.049,95%CI:1.01-1.09,P=0.009),bone mineral density between 30-45 years old(β=0.033,95%CI:0.99-1.07,P=0.127).bone mineral density of 15-30 years old(β=0.025,95%CI:0.95-1.10,P=0.506),bone mineral density of 0-15 years old(β=0.006,95%CI:0.96-1.04,P=0.716).Similar results were obtained from the MR-Egger regression and weighted median estimator analyses.These findings indicate that type 2 diabetes mellitus may be one of the protective factors of bone mineral density,and there is a correlation with age.

Objective To understand cognition level and treatment intention of patients with endometriosis(EMs);To evaluate the effects of TCM chronic disease management on EMs patients.Methods The disease cognition level and treatment intention of 1 895 EMs patients from October 2020 to December 2021 in 19 provinces,autonomous regions and municipalities were analyzed through cross-sectional investigation.The cognitive effect of chronic disease management of TCM on 801 patients with EMs from 6 Grade A hospitals in Beijing was evaluated by self-control study.Results The cognition level of EMs patients for the disease was improved with the increase of educational background.Patients generally believed that EMs was a chronic disease,requiring regular review and long-term management.The proportion of patients with high school education or below,junior college education,bachelor degree or above who knew the possibility of malignant changes in EMs was less,only 32.3%,41.6%and 47.7%,respectively.The awareness rate of patients with high school education or below for recurrence after EMs conservative surgery was 46.9%,lower than that of those with junior college education(66.8%)and bachelor degree or above(72.7%).Among the patients with dietary contraindications,the proportion of patients with high school education or below,junior college education,bachelor degree or above who knew the contraindication of the forest frog oil was less,only 20.7%,30.3%and 32.9%,respectively.In the aspect of life adjustment,the awareness of patients was generally high.EMs patients mainly recognized the disease through face-to-face communication with gynecologists.Only 34.4%of patients with high school education or below learned about EMs through WeChat public accounts,APPs and other new media,which was lower than those with junior college education(48.6%)and bachelor degree or above(55.4%).EMs patients generally tend to be treated in comprehensive hospitals,with high acceptance of TCM treatment,mainly TCM decoction,and low acceptance of TCM appropriate technology.After 1 year of TCM chronic disease management,the disease awareness of EMs patients was significantly improved compared with before management,with statistical significance(P<0.05).Conclusion EMs patients with different educational backgrounds have different cognition of the disease,and each has different emphasis.Education and popularization should be carried out according to their knowledge blind spots.Chronic disease management of TCM can improve the disease cognition level of EMs patients.
