Objective:To investigate the relationship between serum miR-501 and miR-195 levels and sensitivity to concurrent chemoradiotherapy in patients with locally advanced cervical cancer (LACC).Methods:Clinical data of 96 patients with LACC admitted to Nanyang Central Hospital from January 2020 to June 2022 were retrospectively analyzed and compared with those of 96 healthy subjects during physical examination in our hospital during the same period to compare the differences of serum miR-501 and miR-195 levels. Tumor status was reviewed at 6 months after concurrent chemoradiotherapy. Patients were divided into the sensitive and resistant groups according to the evaluation criteria of solid tumor efficacy. The relationship between serum miR-501 and miR-195 levels and the sensitivity to concurrent chemoradiotherapy in LACC patients was analyzed by univariate and multivariate analyses. The receiver operating characteristic (ROC) curve was also drawn to predict differential efficacy of concurrent chemoradiotherapy sensitivity in LACC patients. Multivariate analysis was conducted by binary logistic regression analysis. P<0.05 indicated statistically significant differences. Results:In LACC patients, serum miR-501 level was significantly higher, whereas serum miR-195 level was significantly lower than those in physical examination subjects (both P<0.05). Univariate analysis showed that serum miR-501 level at admission in the resistant group was significantly higher, whereas serum miR-195 level was significantly lower than those in the sensitive group (both P<0.05). Multivariate analysis showed that serum miR-501 and miR-195 levels were significantly correlated with the sensitivity to concurrent chemoradiotherapy in LACC patients. The area under the ROC curve (AUC) was 0.736 and 0.913, respectively. Conclusions:The higher the serum miR-501 level and the lower the serum miR-195 level before treatment, the higher the probability of resistance to concurrent chemoradiotherapy in LACC patients. Serum miR-501 and miR-195 levels of LACC patients before treatment have certain predictive value for the sensitivity to concurrent chemoradiotherapy.

Objective To explore the association between green space and the risk of dyslipidemia. Methods ^“Dyslipidemia^” and ^“ Normalized Difference Vegetation Index (NDVI)^” were used as search terms to search PubMed, Embase, and Web of Science databases for studies up to September 2023. ARHQ statistical assessment and review tool and NOS scale were employed to evaluate the quality of the studies. R 4.3.1 software was used for meta-analysis. Results A total of 11 studies were included, of which 5 cross-sectional studies and 5 cohort studies were rated as ^“high quality^”. The results of meta-analysis showed that an increase in NDVI in some buffer zones was associated with reduced risks of hypercholesterolemia, hypertriglyceridemia, low HDL-C, and high LDL-C, while an increase in NDVI in 100m buffer zone was significantly associated with reduced risks of all these four diseases, with hypercholesterolemia (OR=0.87, P<0.05), hypertriglyceridemia (OR=0.94, P<0.05), low HDL-C (OR=0.95, P<0.05), and high LDL-C (OR=0.87, P<0.05). Sensitivity analysis suggested that the results of most meta-analyses were robust. Conclusion With the increase in green space near residential areas, the risk of dyslipidemia may decrease.

Gualou Niubangtang is a classic formula for eliminating swelling and dispersing lumps， commonly used in the clinical treatment of breast diseases in traditional Chinese medicine （TCM）. This paper employed bibliometric methods to collect and organize 12 pieces of data from ancient texts related to Gualou Niubangtang， ultimately screening 10 valid references from 10 ancient Chinese medical books. Information regarding the prescription origin， main indications， formulation principles， drug composition， dosages， preparation methods， and decoction techniques was systematically verified. The results indicate that Gualou Niubangtang originates from the Orthodox Manual of External Medicine （Wai Ke Zheng Zong） by Chen Shigong in the Ming Dynasty.

Through the excavation and organization of ancient literature regarding Gualou Niubangtang， key information has been identified to provide a scientific basis for its clinical application and further development.

Objective: To analyze the developmental trajectories of middle school students loneliness and social support, as well as to explore the interaction between loneliness and social support, so as to provide the evidence based support for the mental health development of adolescents. Methods: A total of 989 first year students from four public middle schools in Xiangxi Tujia and Miao Autonomous Prefecture, Hunan Province were selected for three follow up surveys by a cluster random sampling method (T1:March 2023, T2:June 2023, T3:December 2023). The UCLA Loneliness Scale-20 (ULS-20) and Social Support Scale for University Students (SSSUS) were employed for questionnaire data collection. The growth mixture modeling was utilized to test the developmental trajectories of loneliness and social support among middle school students, while the cross lagged analysis was performed to investigate their mutual influence. Results: The scores for loneliness and social support in T1, T2 and T3 were (43.1±5.8, 42.5± 6.8 , 42.0±6.9; 55.9±12.0, 60.7±15.7, 60.4±16.7), respectively. Correlational analysis revealed a significant negative correlation between loneliness levels (T1, T2, T3) and social support (T1, T2, T3) ( r =-0.47 to -0.36, P <0.01). Growth mixture modeling indicated a linear declining trend of middle school students loneliness, and the developmental trajectory of social support showed a linear increasing trend, with significant individual differences in initial levels and rates of change ( P <0.05). Cross lagged analyses revealed that loneliness levels at T1 negatively predicted social support scores at T2 ( β =-0.16), and loneliness levels at T2 negatively predicted social support scores at T3 ( β =-0.12) ( P <0.05). Additionally, prior loneliness positively predicted its subsequent levels, with path coefficients of 0.58 and 0.47, respectively ( P <0.05). Social support scores at T1 negatively predicted loneliness levels at T2 ( β =-0.10), while scores at T2 negatively predicted loneliness levels at T3 ( β =-0.15) ( P <0.05). Prior loneliness also positively predicted its subsequent levels, with path coefficients of 0.43 and 0.44, respectively ( P <0.05). Conclusion The developmental trajectory of middle school students loneliness demonstrates a decreasing trend, while that of social support exhibits a linear increasing trend, indicating a longitudinal causal relationship between loneliness and social support.

Objective To summarise and analyse the qualitative studies on the factors that influence patient involvement in decision-making for the initial administration of insulin for the patients with Type II diabetes,from the perspectives of patients and healthcare staff in order to provide a reference to promote patient involvement in decision-making.Methods Systematic searches were conducted across databases,such as CINAHL,Cochrane Library,EMBASE,PubMed,Web of Science,PsycINFO,China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP,and SinoMed,for qualitative studies on the factors that affect patient involvement in initial insulin decision-making for the patients with Type II diabetes.The search was limited to articles from the inception of the databases to 30th September,2023.Quality of the included studies was assessed using the Joanna Briggs Institute(JBI)evidence-based healthcare centre for qualitative research quality assessment tool.The results were integrated using a synthesising integration method.Results A total of 19 articles were included,yielding 20 study results,which were categorised into 7 themes of patient decision-making related values,patient role preferences in decision-making,condition of patient,the role of healthcare staff in patient participation in decision-making,professional quality of healthcare staff,relationship between patient and healthcare staff,and the support from a medical institution.The data were ultimately integrated into 4 overarching themes of patient personal factors,healthcare staff factors,patient-staff interaction factors and medical institution factors.Conclusion The involvement of the patients with Type II diabetes in the decision-making for the initial administration of insulin is influenced by patients themselves,healthcare staff and medical institutions.It requires efforts of multiple parties:not only with the patients actively participate in decision-making,but also with the healthcare staff and institutions who provide effective decision supports.

Academic buoyancy refers to the ability of students to successfully overcome typical, non-major academic setbacks and challenges encountered in daily school life. It can affect students' academic behaviors, academic achievements, and emotional experiences. This paper reviews academic buoyancy from four perspectives: its definition, measurement tools, effects, and intervention strategies. Additionally, it analyzes the applicability of introducing academic buoyancy to nursing students in China, with the aim of providing a new perspective to alleviate academic pressure and improve academic behaviors among nursing students.

Modified electroconvulsive therapy(MECT)has a good therapeutic effect on major depressive disorder(MDD),but its mechanism of action is still unclear.In recent years,accumulated studies have confirmed the effects of MECT on brain structure and function using neuroimaging techniques and large datasets obtained through global collaborations and the conclusions are becoming increasingly consistent.For example,there is an increase in gray matter volume in specific brain regions such as the hippocampus and amygdala,an increase in white matter microstructural integrity and normalization of brain functional connections associated with MDD,such as the hippocampus-amygdala-subgenual anterior cingulate cortex-prefrontal cortex network,hippocampus-thalamus-temporal cortex-parietal cortex network,etc.However,the relationship between these changes and the mechanism of MECT action still needs further investigation.This review provides an overview of the research progress on the structural and functional changes of the brain by MECT to provide methodological support and theoretical basis for its better application in clinical diagnosis and treatment.

OBJECTIVE To investigate whether aldo-keto reductases(AKRs)can act as a nitrore-ductase(NR)and bioactivate aristolochic acid Ⅰ(AA-Ⅰ)to produce AA-Ⅰ-DNA adducts.METHODS① Human-induced hepatocytes(hiHeps)and human bladder RT4 cells were used as tool cells and treated with AA-Ⅰ0,0.5,1.0 and 2 μmol·L-1 for 24 h.Cell viability was detected using the CCK-8 method,and the half maximal inhibition concentration(IC50)was calculated using the CCK-8 method and the level of DNA adduct production was calculated.②hiHeps and RT4 cells were treated with AKR inhibitor luteotin(0,5,10 and 25 μmol·L-1)+AA-Ⅰ 0.2 and 1.0 μmol·L-1 for 24 h,respectively,and the levels of DNA adducts were detected by a liquid chromatography-tandem mass spectrometer(LC-MS/MS).③hiHeps cells were incubated with 80 nmol·L-1 small interfering RNAs(si-AKRs)for 48 h and treated with AA-Ⅰ1.0 μmol·L-1 for 24 h.Real-time qualitative PCR(RT-qPCR)method was used to detect the mRNA expression of AKRs gene and LC-MS/MS technology was used to investigate the effect of specific AKR gene knockdown on DNA adduct levels.④500 nmol·L-1 human AKR recombinant proteins AKR1A1 and AA-Ⅰwere incubated in vitro under anaerobic conditions and the formation of AA-Ⅰ-DNA adducts was detected.RESULTS ①The IC50 of AA-Ⅰto hiHeps and RT4 cells was 1.9 and 0.42 μmol·L-1,respec-tively.The level of DNA adduct production of the two cell lines was significantly different(P<0.01).② Luteolin≥5 μmol·L-1 significantly inhibited the production of AA-Ⅰ-DNA adducts in both cells(P<0.05),and there was a concentration-dependent effect in hiHeps cells(P<0.01,R=0.84).③In the AKR family,the knockdown of AKR1A1 gene up to 80%inhibited the generation of AA-Ⅰ-DNA adducts by 30%-40%.④The AA-Ⅰ-DNA adducts were detected in the incubation of recombinant protein AKR1A1 and AA-Ⅰ under anaerobic conditions in vitro,approximately 1 adduct per 107 nucleotides.CONCLU-SION AKR1A1 is involved in AA-Ⅰ bioactivation,providing a reference for elucidation of the carcino-genic mechanism of AA-Ⅰ.

Objective:To explore the therapeutic mechanism of electroacupuncture(EA)in treating Parkinson disease(PD)using Tandem mass tag(TMT)quantitative proteomics technology. Methods:Forty-eight PD patients were randomly divided into a control group and an observation group,with 24 patients in each group.The control group received routine drug treatment,while the observation group received EA in addition to the routine drug treatment.EA was administered for 30 min per session,3 times a week,for a total of 12 weeks.Nine patients from each group were randomly selected to provide peripheral blood serum samples before and after treatment for TMT quantitative proteomics analysis.Differentially expressed proteins between the two groups were compared,and bioinformatics analysis was performed.The screened differentially expressed proteins were validated using enzyme-linked immunosorbent assay(ELISA). Results:In the observation group,scores on the unified Parkinson disease rating scale(UPDRS),UPDRS Ⅱ,and UPDRS Ⅲ were significantly reduced after treatment(P<0.05).In the control group,these scores tended to increase,but the changes were not statistically significant(P>0.05).After treatment,the UPDRS and UPDRS Ⅲ scores in the observation group were significantly lower than those in the control group(P<0.05).The observation group showed 62 differentially expressed proteins,while the control group had 36.Compared to the control group,the observation group had 142 differentially expressed proteins.These proteins were primarily involved in the cyclic adenosine monophosphate(cAMP)signaling pathway,T helper(Th)1 and Th2 cell differentiation,ATP-binding cassette transporter,vascular endothelial growth factor signaling pathway,and high-affinity immunoglobulin E receptor(FcεRI)signaling pathway.ELISA verification indicated that after EA treatment,the levels of α-Synuclein(αSyn)and heat shock protein beta 1(HSPB1)in the observation group were significantly lower than those in the control group(P<0.05),while the regulator of G-protein signaling 10(RGS10)level was significantly higher(P<0.05). Conclusion:EA,combined with routine drug therapy,can significantly improve clinical symptoms of PD,potentially through the regulation of the cAMP signaling pathway and the contents of differentially expressed proteins of αSyn,HSPB1,and RGS10.

Vascular dementia (VaD) is the second commonest type of dementia which lacks of efficient treatments currently. Neuroinflammation as a prominent pathological feature of VaD, is highly involved in the development of VaD. In order to verify the therapeutic potential of PDE1 inhibitors against VaD, the anti-neuroinflammation, memory and cognitive improvement were evaluated in vitro and in vivo by a potent and selective PDE1 inhibitor 4a. Also, the mechanism of 4a in ameliorating neuroinflammation and VaD was systematically explored. Furthermore, to optimize the drug-like properties of 4a, especially for metabolic stability, 15 derivatives were designed and synthesized. As a result, candidate 5f, with a potent IC₅₀ value of 4.5 nmol/L against PDE1C, high selectivity over PDEs, and remarkable metabolic stability, efficiently ameliorated neuron degeneration, cognition and memory impairment in VaD mice model by suppressing NF-κB transcription regulation and activating cAMP/CREB axis. These results further identified PDE1 inhibition could serve as a new therapeutic strategy for treatment of VaD.
