文摘Endoplasmic reticulum stress and mitochondrial dysfunction play important roles in Parkinson s disease,but the regulato ry mechanism remains elusive.Prohibitin-2(PHB2)is a newly discove red autophagy receptor in the mitochondrial inner membrane,and its role in Parkinson’s disease remains unclear.Protein kinase R(PKR)-like endoplasmic reticulum kinase(PERK)is a factor that regulates cell fate during endoplasmic reticulum stress.Parkin is regulated by PERK and is a target of the unfolded protein response.It is unclear whether PERK regulates PHB2-mediated mitophagy thro ugh Parkin.In this study,we established a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-induced mouse model of Parkinson’s disease.We used adeno-associated virus to knockdown PHB2 expression.Our res ults showed that loss of dopaminergic neurons and motor deficits were aggravated in the MPTP-induced mouse model of Parkinson’s disease.Ove rexpression of PHB2 inhibited these abnormalities.We also established a 1-methyl-4-phenylpyridine(MPP+)-induced SH-SY5Y cell model of Parkinson’s disease.We found that ove rexpression of Parkin increased co-localization of PHB2 and microtubule-associated protein 1 light chain 3,and promoted mitophagy.In addition,MPP+regulated Parkin involvement in PHB2-mediated mitophagy through phosphorylation of PERK.These findings suggest that PHB2 participates in the development of Parkinson’s disease by intera cting with endoplasmic reticulum stress and Parkin.

文摘A series of carbon nitride(CN)materials represented by graphitic carbon nitride(g-C_(3)N_(4))have been widely used in bioimaging,biosensing,and other fields in recent years due to their nontoxicity,low cost,and high luminescent quantum efficiency.What is more attractive is that the luminescent properties such as wavelength and intensity can be regulated by controlling the structure at the molecular level.Hence,it is time to summarize the related research on CN structural evolution and make a prospect on future developments.In this review,we first summarize the research history and multiple structural evolution of CN.Then,the progress of improving the luminescence performance of CN through structural evolution was discussed.Significantly,the relationship between CN structure evolution and energy conversion in the forms of photoluminescence,chemiluminescence,and electrochemiluminescence was reviewed.Finally,key challenges and opportunities such as nanoscale dispersion strategy,luminous efficiency improving methods,standardization evaluation,and macroscopic preparation of CN are highlighted.
文摘BACKGROUND Primary liver cancer is the sixth most common cancer worldwide,with hepato-cellular carcinoma(HCC)being the most prevalent form.Despite the current availability of multiple immune or immune combination treatment options,the prognosis is still poor,so how to identify a more suitable population is extremely important.AIM To evaluate the clinical effectiveness of combining lenvatinib with camrelizumab for patients with hepatitis B virus(HBV)-related HCC in Barcelona Clinic Liver Cancer(BCLC)stages B/C,considering various body mass index(BMI)in diffe-rent categories.METHODS Retrospective data were collected from 126 HCC patients treated with lenvatinib plus camrelizumab.Patients were divided into two groups based on BMI:The non-overweight group(BMI<25 kg/m2,n=51)and the overweight/obese group(BMI≥25 kg/m2,n=75).Short-term prognosis was evaluated using mRECIST criteria,with subgroup analyses for non-overweight(BMI:18.5-24.9 kg/m2),overweight(BMI:25-30 kg/m2),and obese(BMI≥30 kg/m2)patients.A Cox proportional hazards regression analysis identified independent prognostic factors for overall survival(OS),leading to the development of a column-line graph model.with subgroup analyses for non-overweight(BMI:18.5-24.9 kg/m2),overweight(BMI:25-30 kg/m2),and obese(BMI≥30 kg/m2)patients.A Cox proportional hazards regression analysis identified independent prognostic factors for overall survival(OS),leading to the development of a column-line graph model.RESULTS Median progression-free survival was significantly longer in the obese/overweight group compared to the non-overweight group.Similarly,the median OS was significantly prolonged in the obese/overweight group than in the non-overweight group.The objective remission rate and disease control rate for the two groups of patients were,respectively,objective remission rate(5.88%vs 28.00%)and disease control rate(39.22%vs 62.67%).Fatigue was more prevalent in the obese/overweight group,while other adverse effects showed no statistically significant differences(P>0.05).Subgroup analysis based on BMI showed that obese and overweight patients had better progression-free survival and OS than non-overweight patients,with obese patients showing the best outcomes.Multifactorial regression analysis identified BCLC grade,alpha-fetoprotein level,portal vein tumor thrombosis,and BMI as independent prognostic factors for OS.The column-line graph model highlighted the importance of BMI as a major predictor of patient prognosis,followed by alpha-fetoprotein level,BCLC classification,and portal vein tumor thrombosis.CONCLUSION BMI is a long-term predictor of the efficacy of lenvatinib plus camrelizumab,and obese/overweight patients have a better prognosis.

文摘BACKGROUND Colorectal polyps,which are characterized by a high recurrence rate,represent preneoplastic conditions of the intestine.Due to unclear mechanisms of pathogenesis,first-line therapies for non-hereditary recurrent colorectal polyps are limited to endoscopic resection.Although recent studies suggest a mechanistic link between intestinal dysbiosis and polyps,the exact compositions and roles of bacteria in the mucosa around the lesions,rather than feces,remain unsettled.AIM To clarify the composition and diversity of bacteria in the mucosa surrounding or 10 cm distal to recurrent intestinal polyps.METHODS Mucosal samples were collected from four patients consistently with adenomatous polyps(Ade),seven consistently with non-Ade(Pol),ten with current Pol but previous Ade,and six healthy individuals,and bacterial patterns were evaluated by 16S rDNA sequencing.Linear discriminant analysis and Student’s t-tests were used to identify the genus-level bacteria differences between groups with different colorectal polyp phenotypes.Pearson’s correlation coefficients were used to evaluate the correlation between intestinal bacteria at the genus level and clinical indicators.RESULTS The results confirmed a decreased level of probiotics and an enrichment of pathogenic bacteria in patients with all types of polyps compared to healthy individuals.These changes were not restricted to the mucosa within 0.5 cm adjacent to the polyps,but also existed in histologically normal tissue 10 cm distal from the lesions.Significant differences in bacterial diversity were observed in the mucosa from individuals with normal conditions,Pol,and Ade.Increased abundance of Gram-negative bacteria,including Klebsiella,Plesiomonas,and Cronobacter,was observed in Pol group and Ade group,suggesting that resistance to antibiotics may be one risk factor for bacterium-related harmful environment.Meanwhile,age and gender were linked to bacteria changes,indicating the potential involvement of sex hormones.CONCLUSION These preliminary results support intestinal dysbiosis as an important risk factor for recurrent polyps,especially adenoma.Targeting specific pathogenic bacteria may attenuate the recurrence of polyps.

文摘BACKGROUND The association between tumor-infiltrating lymphocyte(TIL)levels and the res-ponse to neoadjuvant therapy(NAT)in patients with triple-negative breast cancer(TNBC)remains unclear.AIM To investigate the predictive potential of TIL levels for the response to NAT in TNBC patients.METHODS A systematic search of the National Center for Biotechnology Information PubMed database was performed to collect relevant published literature prior to August 31,2023.The correlation between TIL levels and the NAT pathologic com-plete response(pCR)in TNBC patients was assessed using a systematic review and meta-analysis.Subgroup analysis,sensitivity analysis,and publication bias analysis were also conducted.RESULTS A total of 32 studies were included in this meta-analysis.The overall meta-ana-lysis results indicated that the pCR rate after NAT treatment in TNBC patients in the high TIL subgroup was significantly greater than that in patients in the low TIL subgroup(48.0%vs 27.7%)(risk ratio 2.01;95%confidence interval 1.77-2.29;P<0.001,I2=56%).Subgroup analysis revealed that the between-study hetero-geneity originated from differences in study design,TIL level cutoffs,and study populations.Publication bias could have existed in the included studies.The meta-analysis based on different NAT protocols revealed that all TNBC patients with high levels of TILs had a greater rate of pCR after NAT treatment in all protocols(all P≤0.01),and there was no significant between-protocol difference in the statistics among the different NAT protocols(P=0.29).Additionally,sensitivity analysis demonstrated that the overall results of the meta-analysis remained consistent when the included studies were individually excluded.CONCLUSION TILs can serve as a predictor of the response to NAT treatment in TNBC patients.TNBC patients with high levels of TILs exhibit a greater NAT pCR rate than those with low levels of TILs,and this predictive capability is con-sistent across different NAT regimens.

文摘BACKGROUND Gestational diabetes mellitus(GDM)is a condition characterized by high blood sugar levels during pregnancy.The prevalence of GDM is on the rise globally,and this trend is particularly evident in China,which has emerged as a significant issue impacting the well-being of expectant mothers and their fetuses.Identifying and addressing GDM in a timely manner is crucial for maintaining the health of both expectant mothers and their developing fetuses.Therefore,this study aims to establish a risk prediction model for GDM and explore the effects of serum ferritin,blood glucose,and body mass index(BMI)on the occurrence of GDM.AIM To develop a risk prediction model to analyze factors leading to GDM,and evaluate its efficiency for early prevention.METHODS The clinical data of 406 pregnant women who underwent routine prenatal examination in Fujian Maternity and Child Health Hospital from April 2020 to December 2022 were retrospectively analyzed.According to whether GDM occurred,they were divided into two groups to analyze the related factors affecting GDM.Then,according to the weight of the relevant risk factors,the training set and the verification set were divided at a ratio of 7:3.Subsequently,a risk prediction model was established using logistic regression and random forest models,and the model was evaluated and verified.RESULTS Pre-pregnancy BMI,previous history of GDM or macrosomia,hypertension,hemoglobin(Hb)level,triglyceride level,family history of diabetes,serum ferritin,and fasting blood glucose levels during early pregnancy were determined.These factors were found to have a significant impact on the development of GDM(P<0.05).According to the nomogram model’s prediction of GDM in pregnancy,the area under the curve(AUC)was determined to be 0.883[95%confidence interval(CI):0.846-0.921],and the sensitivity and specificity were 74.1%and 87.6%,respectively.The top five variables in the random forest model for predicting the occurrence of GDM were serum ferritin,fasting blood glucose in early pregnancy,pre-pregnancy BMI,Hb level and triglyceride level.The random forest model achieved an AUC of 0.950(95%CI:0.927-0.973),the sensitivity was 84.8%,and the specificity was 91.4%.The Delong test showed that the AUC value of the random forest model was higher than that of the decision tree model(P<0.05).CONCLUSION The random forest model is superior to the nomogram model in predicting the risk of GDM.This method is helpful for early diagnosis and appropriate intervention of GDM.
文摘BACKGROUND Currently,pediatric surgeons are challenged by a lack of consensus on the optimal management strategy(conservative or surgical)for children with Bell’s stage II necrotizing enterocolitis(NEC).AIM To evaluate the clinical efficacy of peritoneal drainage in very-low-birth-weight(VLBW)neonates with modified Bell’s stage II NEC.METHODS This was a retrospective analysis of 102 NEC(modified Bell’s stage II)neonates born with VLBW who were treated at the Fujian Children’s Hospital(Fujian Branch of Shanghai Children’s Medical Center)between January 2017 and January 2020;these included 24 cases in the peritoneal drainage group,36 cases in the exploratory laparotomy group,and 42 cases in the conservative treatment group.RESULTS The general characteristics were comparable in the three groups(P>0.05).Compared with conservative treatment,peritoneal drainage was associated with significantly shorter fasting time,abdominal distension relief time,fecal occult blood(OB)negative conversion time,and reduced hospital length of stay(HLOS)(P<0.05 for all).Despite some advantages of peritoneal drainage over conservative treatment in terms of cure,conversion to laparotomy,intestinal perforation,intestinal stenosis,and abdominal abscess rates,the differences were not statistically significant(P>0.05).Compared to exploratory laparotomy,the fecal OB negative conversion time was significantly shorter in the peritoneal drainage group(P<0.05);similarly,the exploratory laparotomy group showed longer fasting time,abdominal distension relief time,HLOS,and higher complication rate compared to peritoneal drainage group,but the between-group differences were not statistically significant(P>0.05).CONCLUSION Peritoneal drainage,an easy-to-operate procedure,can improve the clinical symptoms of VLBW neonates with Bell’s stage II NEC and help reduce the HLOS.
