Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. Scutellaria barbata D. Don (SB) and Scleromitrion diffusum (Willd.) R. J. Wang (SD), a classic TCM herbal pair exhibited anti-inflammatory and antioxidant activities. Using advanced chromatographic separation technology, we enriched the effective fractions of water extracts from SB-SD, obtaining self-assembled herbal nanoparticles (SB and SD nanoparticles, SSNPs) rich in flavonoids and terpenoids. These SSNPs demonstrated robust antioxidant properties in vitro and mitigated AKI progression in vivo by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Oral administration of SSNPs in mice resulted in absorption into the bloodstream, formation of a protein corona, reduced macrophage phagocytosis, and enhanced bioavailability and renal targeting. Furthermore, we investigated the self-assembly principle of SSNPs using representative flavonoids and terpenoids. Kinetic studies and in situ transmission electron microscopy (in situ TEM) revealed that these compounds self-assemble via supramolecular forces like hydrogen bonding and π-π interactions, forming stable nanostructures. This study elucidates the renoprotective effects and mechanisms of SB and SD, and provides a novel approach for the development of TCM-based nanomedicines, highlighting the potential of nano-TCM in AKI treatment.

Objective To investigate the effects and underlying mechanisms of down-regulating m6A demethylase fat mass and obesity-associated protein(FTO)on proplatelet formation in the MEG-01 megakaryocytic cells.Methods ①MEG-01 cells were treated with 1 nmol/L phorbol myristate acetate(PMA)(treatment group)or DMSO(control group)for 72 h.FTO expression was measured by Western blotting and RT-qPCR.② MEG-01 cells were infected with targeted FTO shRNA(knockdown group,sh-FTO)or negative control shRNA(negative control group,sh-NC)viruses.FTO knockdown group and negative control group MEG-1 cells were treated with 1 nmol/L PMA for 72 h,and the protein and mRNA expression levels of FTO were detected by Western blotting and RT-qPCR.Cell cycle,viability and apoptosis were assessed by propidium iodide(PI)DNA staining,CCK-8 assay and Annexin V-FITC/PI double staining and TUNEL staining.The expression of cleaved Caspase-3 protein was determine by Western blotting.Megakaryocyte maturation was assessed by CD41/CD61 staining.Proplatelet formation was observed under bright field and detected by CD61 immunofluorescence assay.The expression of apoptosis-related molecules(Caspase3,BAD,BAK1,BCL2 and MCL1)was detected by RT-qPCR,and the protein change of BCL2 was further verified by Western blotting.The dataset was screened out from the gene expression omnibus(GEO)database,and then analyzed with University of California,Santa Cruz(UCSC)genome browser to compare the methylation sequencing peaks on BCL2 mRNA,and m6A methylated RNA immunoprecipitation(m6A-RIP)was used to assess the m6A methylation levels of BCL2 target gene mRNAs in MEG-01 megakaryocytes.Then,the changes in the m6A methylation enrichment level of BCL2 mRNA were observed between the sh-NC group and the sh-FTO group.mRNA stability and ribosome profiling assays were performed to assess translational efficiency of target genes.Results ①PMA treatment upregulated the expression of FTO at protein(P＜0.05)and mRNA(P＜0.01)levels.② FTO shRNA resulted in reduced FTO expression at both mRNA and protein levels(P＜0.01).Compared to the negative control group,the FTO knockdown group showed more cells arrested at the G1/S phase[(60.80±1.29)%vs(72.13±1.18)%,P＜0.01],significantly reduced cell viability[(1.17±0.03)%vs(0.69±0.05)%,P＜0.01],increased Annexin V-FITC/PI positive cells[(12.87±0.83)%vs(17.45±1.58)%,P＜0.01],more TUNEL positive cells[(1.03±0.27)%vs(17.49±9.91)%,P＜0.01],enhanced protein level of cleaved Caspase-3(P＜0.01),decreased proportion of CD41/CD61 positive cells[(51.63±1.13)%vs(34.08±0.53)%,P＜0.01],and less proplatelet formation in MEG-01 megakaryocytes[(26.49±6.73)%vs(13.31±5.97)%,P＜0.01].③Compared to sh-NC group,the FTO knockdown group had significantly decreased protein and mRNA expression of anti-apoptotic molecule BCL2(P＜0.01).UCSC GEO sequencing data revealed there were m6A methylation modification sites on BCL2 mRNA,which was verified through m6A-RIP experiment in MEG-01 megakaryocytes.Compared with GAPDH mRNA,BCL2 mRNA exhibited a significantly enriched m6A signal(P＜0.01).Compared to sh-NC group,a significant increase in m6A methylation modification was observed on BCL2 mRNA.BCL2 mRNA stability was significantly decreased,and its translation efficiency significantly was decreased(P＜0.01).Conclusion m6 A demethylase FTO rgulates BCL2 mRNA stability and translation efficiency,thereby promoting proplatelet formation in MEG-01 megakaryocytes.

Objective To understand the prevalence and risk factors of hyperuricemia in electronics factory workers in Wuhan, and to provide evidence for the health protection of electronics factory workers. Methods A total of 1 415 employees in an electronics factory in Wuhan were selected as the research subjects, and the physical examination and determination of various biochemical indicators, as well as questionnaire survey were carried out. Results The detection rate of hyperuricemia among workers in the electronics factory in Wuhan was 32.43%, with 36.33% for men and 14.11% for women, and the difference was statistically significant ( χ²＝46.077，P＜0.001). The detection rate of hyperuricemia was the highest (33.77%) among those with university or college education, followed by graduate students and above (31.50%). Compared with subjects with good lifestyle habits, people with drinking habits had higher hyperuricemia detection rate (49.38%), and the difference was statistically significant (P =0.001). The detection rates of hyperuricemia in those with central obesity and elevated alanine aminotransferase were 48.23% and 61.29%, respectively, which were significantly higher than those in the subjects without the above diseases (26.91% and 27.21%, respectively), and the differences were statistically significant (P <0.001). Obese people had the highest detection rate of hyperuricemia (66.95%), followed by overweight people (43.75%), and the difference was statistically significant (P <0.001). Multivariate logistic analysis showed that alcohol drinking (OR=1.836, 95% CI=1.139-2.961, P =0.013) and body mass index ≥ 24 kg/m² (OR=2.175, 95% CI=1.686 -2.806, P <0.001) were risk factors for hyperuricemia in electronic factory workers. Elevated alanine aminotransferase (ALT) was significantly correlated with hyperuricemia (OR=2.964, 95%CI=2.146-4.095 , P <0.001). Female gender was a protective factor for hyperuricemia in workers in the electronics factory (OR=0.441, 95%CI=0.297-0.653 , P <0.001). Conclusion The detection rate of hyperuricemia among workers in an electronics factory in Wuhan is high, and the detection rate of hyperuricemia in men is higher than that in women. Alcohol consumption, overweight and obesity will increase the risk of hyperuricemia. Elevated ALT is associated with hyperuricemia. Maintaining an ideal body mass index and establishing a good lifestyle play an important role in preventing hyperuricemia.

Objective To compare the clinical safety and efficacy of CT-guided hook-wire localization of≤10mm pulmonary ground-glass nodule(GGN)via different path ways before video-assisted thoracoscopic surgery(VATS).Methods The clinical data of a total of 128 patients with 10 mm pulmonary GGN,who received CT-guided hook wire localization before VATS at The Third Hospital of Mianyang of China between July 2018 and March 2023,were retrospectively analyzed.According to the puncturing localization path way mode,the patients were divided into vertical puncturing group(n=88)and non-vertical puncturing group(n=40).The number of puncturing times,the time spent for puncturing localization,the success rate of puncture,the operation time of VATS,and puncture-related complications of the two groups were recorded.Results No statistically significant differences in the gender,age,smoking history,GGN location,puncture position,nodule size,density characteristics of GGN,emphysema,and nodules-pleura distance existed between the two groups(all P＞0.05).Compared with non-vertical puncturing group,in vertical puncturing group the number of puncturing times was smaller,the time spent for localization was shorter,the incidence of pneumothorax was lower,and the operation time of VATS was shorter,the differences in all the above indexes between the two groups were statistically significant(all P＜0.05);and the subgroup analysis of patients whose GGN was overlapped with rib shadow obtained the same results.Binary logistic regression analysis revealed that non-vertical puncturing and the number of puncturing times were the independent risk factors for the occurrence of pneumothorax.Conclusion CT-guided hook-wire localization of≤10mm pulmonary GGN before VATS is clinically safe and effective.Under the condition when the lesion can be localized within the range of 2.0cm and the shadow overlapping of GGN with the rib and blood vessel can be effectively avoided,vertical puncturing path way mode should be preferred,which can effectively reduce the incidence of pneumothorax and shorten the operation time of VATS.

Objective:To explore a simplified and efficient early prediction model for severe acute pancreatitis (SAP) using the least absolute shrinkage and selection operator (LASSO) regression, and to construct both logistic regression and decision tree models. The aim is to identify high-risk individuals, guide clinical treatment, and improve patient outcomes.Methods:A retrospective analysis was conducted on the clinical data of 412 patients with acute pancreatitis admitted to the Emergency and Gastroenterology Departments of the First Affiliated Hospital of Anhui Medical University and its High-tech Branch from November 2020 to September 2023. LASSO regression was employed to identify factors significantly associated with SAP, followed by the construction of a multivariate logistic regression model and a decision tree model. The predictive performance of these models was evaluated and compared to the bedside index for severity in acute pancreatitis (BISAP).Results:Among the 412 patients, the incidence of SAP was 12.14% ( n=50). Seven variables significantly associated with SAP severity were identified by LASSO regression, including respiratory rate at admission, pain score at admission, pleural effusion, fibrin degradation products, C-reactive protein, serum creatinine, and serum albumin. The logistic regression model incorporated four variables: pleural effusion, pain score at admission, serum creatinine, and serum albumin. In the training set, the model demonstrated a sensitivity of 0.528, specificity of 0.984, accuracy (95% CI) of 0.928 (0.892-0.955), Kappa value of 0.606, and AUC (95% CI) of 0.920 (0.862-0.979). In the testing set, the model showed a sensitivity of 0.643, specificity of 0.925, accuracy (95% CI) of 0.891 (0.822-0.941), Kappa value of 0.519, and AUC (95% CI) of 0.923 (0.861-0.985). The decision tree model comprised three branches and four terminal nodes, indicating that serum creatinine, serum albumin, and pleural effusion could effectively predict SAP occurrence. In the training set, the decision tree model had a sensitivity of 0.500, specificity of 0.973, accuracy (95% CI) of 0.914 (0.876-0.944), Kappa value of 0.544, and AUC (95% CI) of 0.812 (0.731-0.894). In the testing set, the model exhibited a sensitivity of 0.500, specificity of 0.925, accuracy (95% CI) of 0.875 (0.802-0.928), Kappa value of 0.412, and AUC (95% CI) of 0.709 (0.565-0.853). The DeLong test revealed that in the training set, the AUC of the logistic regression model was significantly greater than that of the decision tree model ( P<0.01) and the BISAP score ( P<0.001), while the AUC difference between the decision tree model and the BISAP score was not statistically significant ( P=0.762). In the testing set, the AUC of the logistic regression model was again greater than that of the decision tree model ( P<0.01) and the BISAP score ( P=0.018), whereas the AUC of the decision tree model was lower than that of the BISAP score ( P=0.017). Conclusions:Both the logistic regression and decision tree models demonstrate good predictive value for SAP, and their combined use may provide valuable guidance for clinical practice.

Objective:To compare the efficacy and safety of azacitidine combined with venetoclax or CAG regimen in the treatment of newly treated elderly patients with acute myeloid leukemia (AML).Methods:A retrospective cohort study was conducted. The clinical data of 34 newly treated elderly patients with AML treated in the Fifth People's Hospital of Datong from May 2018 to August 2023 were retrospectively analyzed. According to the treatment regimen, all patients were divided into venetoclax group (azacitidine + venetoclax, 17 cases) and CAG group (azacitidine + CAG regimen, 17 cases). The clinicopathological characteristics, efficacy, adverse reactions and survival of the both groups were compared.Results:There were no statistically significant differences in the clinical data of both groups (all P > 0.05). The complete remission (CR) rate and the objective response rate (ORR) in venetoclax group were higher than those in CAG group [CR: 70.6%(12/17) vs. 47.1% (8/17); ORR: 82.4% (14/17) vs. 64.7% (11/17)],while the differences in CR and ORR were not statistically significant (χ 2 = 2.00, P = 0.163; χ 2 = 2.00, P = 0.244). The follow-up time[ M ( Q1, Q3)] was 25.4 months (7.2 months, 60.3 months). At the end of follow-up, 19 of 34 patients survived (13 cases in venetoclax group and 6 cases in CAG group); 15 died (4 cases in venetoclax group and 11 cases in CAG group). The median overall survival (OS) time was 14.22 months (95% CI: 8.2-60.3 months) and 10.56 months (95% CI: 7.2-50.2 months), respectively in venetoclax group and CAG group;the median progression-free survival (PFS) time was 9.97 months (95% CI: 5.4-40.5 months) and 6.82 months (95% CI: 5.0-36.2 months), respectively, and there were no statistically significant differences in OS and PFS between the two groups (all P > 0.05). Grade 3-4 hematological adverse reactions occurred in 16 and 14 patients in venetoclax group and CAG group, respectively. There were no significant differences in granulocyte deficiency time, platelet deficiency time, infection and bleeding incidence between the two groups (all P > 0.05). Conclusions:Azacitidine combined with venetoclax or CAG regimen have better clinical efficacy and safety for newly treated elderly patients with AML.

Objective:To analyze the epidemiological and clinical characteristics of respiratory syncytial virus (RSV) infection in children in Jiangsu Province from 2014 to 2023.Methods:The acute respiratory infection cases in children aged 0-14 years were selected from outpatient/emergency or inpatient departments in 2 surveillance sentinel hospitals, respectively, in Nanjing, Suzhou and Taizhou of Jiangsu from 1 July 2014 to 31 December 2023, and RSV nucleic acid test was conducted and the intensity of the RSV infection was accessed by WHO influenza epidemiological threshold method, and case information and clinical data were collected. χ2 test was used to compare the differences between groups, and the Bonferroni method was used for pairwise comparisons between groups. Results:In 4 946 cases of acute respiratory infections, the RSV positive rate was 8.21% (406/4 946), and the age M( Q1, Q3) of the cases was 1 (0, 3) years. The RSV positive rate was 10.92% (258/2 362) during 2014-2019 and 6.06% (118/1 948) during 2019-2023, the difference was significant ( χ2=31.74, P<0.001). RSV infection mainly occurred from October to March during 2014-2019, with the incidence peak in December and moderate or higher intensity. The seasonality of RSV infection was not obvious during 2019-2023, with low intensity. The RSV positive rate was highest in children in age group 0- years (17.85%, 151/846), and the positive rate declined gradually with age ( χ2=184.51, P<0.001). The RSV positive rate was higher in inpatient cases (9.84%, 244/2 480) than in outpatient/emergency cases (6.57%, 162/2 466) ( χ2=17.54, P<0.001). In the 155 RSV infection cases with complete clinical data, the clinical symptoms mainly included cough (99.35%, 154/155), fever (55.48%, 86/155), and shortness of breath (45.16%, 70/155). In the cases aged <6 months, the proportion of those with fever was low, but the proportion of those with shortness of breath, transferred to intensive care units, and receiving oxygen therapy were higher (all P<0.05). Children aged <6 months and those with underlying diseases were more likely to have severe RSV infection (all P<0.05). Conclusions:RSV infection in children in Jiangsu Province showed seasonal prevalence in winter from 2014 to 2019. Since 2020, the seasonal characteristics of the epidemic have changed, the epidemic period has been dispersed and the epidemic intensity has decreased. Infants <1 year old were at high risk for RSV infection, and those <6 months old and with underlying diseases might have severe infection.

Objective To analyze the clinical distribution characteristics,drug resistance,and homology of carbapenem resistant Escherichia coli(CRE)isolated from a tertiary hospital from 2019 to 2023,in order to provide a basis for rational drug use and hospital infection prevention and control.Methods A retrospective a-nalysis was conducted on non repetitive CRE strains clinically isolated from 2019 to 2023 in the hospital.WHONET 5.6 software was used to analyze the isolation rate,clinical distribution characteristics,and patho-gen resistance of CRE strains.CRE strains clinically isolated in 2022 in the hospital were collected as research objects,and the resistance gene expression and homology with hospital acquired infection clones were detected through polymerase chain reaction amplification and sequence analysis.Results From 2019 to 2023,a total of 455 non duplicated CRE strains were detected in clinical specimens of the hospital,with a detection rate of 6.00％.The annual detection rates were 72 strains(6.59％)in 2019,91 strains(8.31％)in 2020,117 strains(7.99％)in 2021,78 strains(4.76％)in 2022,and 97 strains(4.24％)in 2023.The CRE detection rates showed a downward trend from 2020 to 2023(P＜0.05).The top two strains in terms of proportion among CRE strains were 324 strains(71.21％)of carbapenem resistant Klebsiella pneumoniae(CRKP)and 57 strains(12.53％)of carbapenem resistant Escherichia coli(CREC).In addition,the detection rate of CRKP showed a decreasing trend from 2021 to 2023,while the detection rate of CREC showed an increasing trend from 2021 to 2023(P＜0.05).The strains mainly came from intensive care medicine,geriatrics,and neurology departments.Most of the CRE strains were isolated from sputum samples,with a detection rate of 67.96％,followed by urine samples with a detection rate of 21.97％.CRE had a very high resistance to common clinical antibiotics,with resistance rates of 94.32％and 96.37％to ertapenem and imipenem,respectively.Out of 78 strains of CRE,55 strains(70.51％)were found to have blaKPC-2 genotype and 14 strains(17.95％)were found to have blaNDM genotype.The detection rate of CRKP MLST typing ST11 was 68.89％(31/45).Con-clusion The detection rate of CRE in the hospital is showing a downward trend,but the resistance of the strains is still high.CRKP is the main strain of CRE strains,mainly carrying blaKPC-2 gene,and ST11 type is the main one.Clinical departments(especially critical care departments)should choose antibiotics reasonably based on the results of drug sensitivity tests for treatment and strengthen hospital management to further curb the growth of CRE.

BackgroundChronic obstructive pulmonary disease （COPD） is a common chronic respiratory disease， and patients with COPD often experience substantially emotional difficulties， such as anxiety and depression， all of which may cause serious detriment to the prognosis of patients. As a non-pharmacological intervention in clinical practice， group mindfulness-based stress reduction therapy （MBSR） is beginning to emerge， while has rarely been studied in COPD patients with concurrent emotional difficulties. ObjectiveTo evaluate the effects of group MBSR on depression， state of mindfulness and pulmonary function in stable COPD patients， so as to provide references for the application of group MBSR in patients with COPD. MethodsA total of 97 patients with stable COPD who were followed up in the Department of Respiratory and Critical Care Medicine of Mianyang Third People's Hospital from January to October 2019 were selected as the study objects， and they were assigned into study group （n=50） and control group （n=47） by random number table method. All individuals received routine medication therapy and an 8-week health education， based on this， participants in study group partook an 8-week intervention comprising group MBSR. At the baseline， 4 weeks and 8 weeks of intervention， participants were assessed with Self-rating Depression Scale （SDS）， Five Facet Mindfulness Questionnaire （FFMQ） and COPD Assessment Test （CAT）， as well as the pulmonary function testing. ResultsThere were 41 patients in study group and 42 cases in control group completed the study. The group * time interaction was interpreted as significant between two groups for SDS， FFMQ and CAT scores （F=54.858， 86.161， 69.862， P<0.01）. Baseline SDS， FFMQ and CAT scores of the two groups yielded no statistical difference between two groups （F=0.240， 0.052， 0.019， P>0.05）， while study group scored lower on SDS and CAT （F=12.900， 38.511， 7.797， 28.824， P<0.01） and higher on FFMQ （F=27.324， 82.412， P<0.01） than those of the control group after 4 and 8 weeks of intervention. With the prolongation of intervention time in study group， participants demonstrated an overall reduction in SDS and CAT scores （F=109.753， 124.144， P<0.01）， and an increase in FFMQ scores （F=228.194， P<0.01）. There were no between-group differences in forced expiratory volume in one second as percentage of predicted volume （FEV1%pred） after 4 and 8 weeks of intervention （F=0.104， P=0.748） ， and the within-group changes in FEV1%pred value over the intervention period in study group was not statistical （F=0.561， P=0.458）. ConclusionGroup MBSR may help relieve depressive symptoms， enhance mindfulness level， and alleviate clinical symptoms in stable COPD patients， but has no effect on pulmonary function. ［Funded by Mianyang Health and Health Commission Scientific Research Project （number， 201916）］

Objective    To analyze the short-term and long-term efficacy of staged coronary artery bypass grafting (CABG) and carotid artery stenting (CAS) compared with CABG alone in patients with coronary heart disease with preoperative history of stroke and carotid stenosis. Methods    We reviewed the clinical data of 55 patients (48 males, 7 females, aged 67.62±7.06 years) with coronary heart disease and carotid stenosis who had a history of stroke and underwent CABG+CAS or CABG alone in Zhongshan Hospital from 2008 to 2017. There were 13 patients in the staged CABG+CAS group and 42 patients in the CABG alone group. The differences in the incidence of perioperative adverse events and long-term survival between the two groups were studied, and univariate and multivariate analyses were carried out to determine the independent risk factors of long-term adverse events. Results     Perioperative adverse events occurred in 1 (7.69%) patient of the staged CABG+CAS group, and 4 (9.52%) patients of the CABG alone group (P=0.84). During the follow-up period (67.84±37.99 months), the long-term survival rate of patients in the staged CABG+CAS group was significantly higher than that in the CABG alone group (P=0.02). The risk of long-term adverse events in the staged CABG+CAS group was 0.22 times higher than that in the CABG alone group (95%CI 0.05-0.92, P=0.04). Conclusion    Staged CABG+CAS can significantly improve the long-term survival prognosis without increasing the perioperative risk. It is a safe and effective treatment, but prospective randomized studies are still needed to further confirm this finding.
