Objective To investigate the role of miR-27a-3p in sevoflurane-induced neurocognitive dysfunction.Methods Bioinformatics prediction and validation:Predicted the target genes of miR-27a-3p using bioinformatics databases,and verified the interaction between miR-27a-3p and target genes using dual-luciferase reporter gene assay and Western blot.Cell experiments:Cells were divided into two groups,the miR-27a-3p interference control(Sevo+NC)group was transfected with miR-27a-3p interference control plasmid,and the miR-27a-3p interference treatment(Sevo+anti-miR-27a-3p)group was transfected with miR-27a-3p interference plasmid.Before transfection,the plasmids were treated with 4％sevoflurane for 6 h.Western blot was used to detect the protein expression levels of tau and phosphorylaed tau(p-tau)in SY5Y cells of each group.Animal experiments:Mice were randomly divided into control group(no treatment),sevoflurane group(treated with 4％sevoflurane only),miR-27a-3p interference control group(Sevo+NC,injected with miR-27a-3p interference control plasmid after 4％sevoflurane treatment)and miR-27a-3p interference treatment group(Sevo+anti-miR-27-3p,injected with miR-27a-3p interference plasmid after 4％sevoflurane treatment).The neurocognitive abilities of mice were tested using the water maze experiment,and the level of tau phosphorylation in the hippocampal tissue of mice was detected by immunofluorescence.Results Bioinformatics prediction and validation:Bioinformatics prediction suggested that presenilin 1(PSEN1)might be a target gene of miR-27 a-3p.Dual-luciferase reporter gene assay and Western blot showed that miR-27 a-3p interacted with PSEN1.Cell experiments:The levels of p-tau in Sevo+NC group and Sevo+anti-miR27-3p group were 0.69±0.08 and 0.21±0.05,respectively.Animal experiments:The escape latency times of the control group,sevoflurane group,Sevo+NC group and Sevo+anti-miR-27-3p group were(27.54±3.67),(52.38±6.12),(55.16±5.79)and(38.46±4.78)s,respectively;the results of the novel object exploration index were 0.78±0.11,0.31±0.07,0.33±0.06,and 0.57±0.08,respectively.Immunofluorescence detection showed a significant decrease in p-tau levels in the hippocampal tissue of mice(P＜0.05).Conclusion miR-27 a-3p regulates the p-tau protein by targeting the PSEN1 gene,and interfering with miR-27 a-3p can alleviate sevoflurane-induced neurocognitive dysfunction in mice.

Objective:To investigate the current situation of body image and stigma of drug-resistant tuberculosis patients treated with Clofazimine, and analyze the correlation between them.Methods:A cross-sectional study was conducted using convenience sampling method to investigate 150 patients with drug-resistant tuberculosis treated with Clofazimine in tuberculosis ward of Chengdu Public Health Clinical Medical Center from October 2020 to October 2021. The general questionnaire, Body Image Scale (BIS) and Tuberculosis Related Stigma Scale were used to conduct a questionnaire survey.Results:A total of 130 questionnaires were effectively collected. The body image score of 130 patients with drug-resistant tuberculosis treated with Clofazimine was (20.51 ± 6.80) points; the score of stigma was (17.78 ± 6.92) points. There was a positive correlation between the total score of disease shame and the total score of body image ( r=0.544, P<0.05). Conclusions:Patients with drug-resistant tuberculosis treated with Clofazimine have body image disorder and stigma, and the two are positively correlated. Caregivers should carry out psychological assessment and intervention at an early stage to improve the patient′s mental health level.

Alcoholic liver disease (ALD) is a growing global health concern, and its early pathogenesis includes steatosis and steatohepatitis. Inhibiting lipid accumulation and inflammation is a crucial step in relieving ALD. Evidence shows that puerarin (Pue), an isoflavone isolated from Pueraria lobata, exerts cardio-protective, neuroprotective, anti-inflammatory, antioxidant activities. However, the therapeutic potential of Pue on ALD remains unknown. In the study, both the NIAAA model and ethanol (EtOH)-induced AML-12 cell were used to explore the protective effect of Pue on alcoholic liver injury in vivo and in vitro and related mechanism. The results showed that Pue (100 mg·kg^-1) attenuated EtOH-induced liver injury and inhibited the levels of SREBP-1c, TNF-α, IL-6 and IL-1β, compared with silymarin (Sil, 100 mg·kg^-1). In vitro results were consistent within vivo results. Mechanistically, Pue might suppress liver lipid accumulation and inflammation by regulating MMP8. In conclusion, Pue might be a promising clinical candidate for ALD treatment.

OBJECTIVE: To investigate the efficacy and safety of venetoclax (VEN) combined with demethylating agents (HMA) in the treatment of relapsed/refractory acute myeloid leukemia (R/R AML). METHODS: The clinical data of 26 adult R/R AML patients who received the combination of VEN with azacitidine (AZA) or decitabine (DAC) in Huai'an Second People's Hospital from February 2019 to November 2021 were retrospectively analyzed. The treatment response, adverse events as well as survival were observed, and the factors of influencing the efficacy and survival were explored. RESULTS: The overall response rate (ORR) of 26 patients was 57.7% (15 cases), including 13 cases of complete response (CR) and CR with incomplete count recovery (CRi) and 2 cases of partial response (PR). Among the 13 patients who got CR/CRi, 7 cases achieved CRm (minimal residual disease negative CR) and 6 cases did not, with statistically significant differences in overall survival (OS) and event-free survival (EFS) between the two groups (P=0.044, 0.036). The median OS of all the patients was 6.6 (0.5-15.6) months, and median EFS was 3.4 (0.5-9.9) months. There were 13 patients in the relapse group and refractory group, respectively, with response rate of 84.6% and 30.8% (P=0.015). The survival analysis showed that the relapse group had a better OS than the refractory group (P=0.026), but there was no significant difference in EFS (P=0.069). Sixteen patients who treated for 1-2 cycles and 10 patients who treated for more than 3 cycles achieved response rates of 37.5% and 90.0%, respectively (P=0.014), and patients treated for more cycles had superior OS and EFS (both P<0.01). Adverse effects were mainly bone marrow suppression, complicated by various degrees of infection, bleeding, and gastrointestinal discomfort was common, but these could be all tolerated by patients. CONCLUSION VEN combined with HMA is an effective salvage therapy for patients with R/R AML and is well tolerated by patients. Achieving minimal residual disease negativity is able to improve long-term survival of patients.

C2H2 transcription factors play an important role in plant growth, development and the regulation of secondary metabolism. This article identifies members of the C2H2 gene family in Cannabis sativa L. at the genome level. Chromosomal location and linkage, evolutionary relationships, and identification of conserved motifs was determined from the C. sativa genome and transcriptome data using bioinformatics tools and on-line websites such as TBtools, MEGA software, NCBI, PlantTFDB, ExPASy, HMMSCAN, MEME, WoLFPSORT and PlantCARE. The results show that C. sativa contains 30 members of the C2H2 gene family (named CsC2H2-1-CsC2H2-30) distributed on 9 chromosomes. The encoded proteins range in length from 138 to 635 amino acids, and the theoretical isoelectric points range from 5.85 to 9.52. Molecular weights range from 15 909.48 to 68 445.53 Da. Transcriptome analysis showed that CsC2H2 was differentially expressed in the female flowers, bracts, leaves, and stems of the Diku variety and female flowers of nine different varieties of C. sativa. Quantitative real-time PCR verified that CsC2H2-1, CsC2H2-5, and CsC2H2-19 were significantly expressed in the female flowers and bracts of the Diku variety. This provides a theoretical basis for in-depth study of the function of the C2H2 gene family and the breeding of high-quality C. sativa varieties.

Objective: The current study aims to explore precipitating and social risk factors for internet addiction (IA) in university undergraduate students, and to provide evidence for interventions and the early prevention of IA in different genders. Methods: Four thousand eight hundred and fifty-eight college sophomores completed an online survey on their internet use-related behaviours and social risk factors. Results: We found that more male (8.3%) than female students (5.4%) had moderate and severe IA. The main online activity in the moderate and severe IA groups was online gaming in males and online streaming in females. Roommates engaging in similar internetbased entertainment was a risk factor of IA only for males, while not being in a romantic relationship was a risk factor of IA for females only. Infatuation with the internet before college and adjustment problems for college life were shared risk factors for both genders in the mild and moderate IA groups. Conclusion IA was a common phenomenon in college students with shared and unique precipitating and social risk factors in males and females. The gender-sensitive risk factors for IA warranted earlier and individualized intervention and prevention strategies for IA in this population.

OBJECTIVE: Sorafenib has been extensively used for the treatment of advanced hepatocellular carcinoma (HCC), and Chinese herbal medicine has also been used to manage advanced HCC. The present work evaluates the effectiveness and safety of Jiedu (JD) Granule, a compound of traditional Chinese herbal medicine, side-by-side with sorafenib for the treatment of advance HCC. METHODS: Patients with advanced HCC receiving treatment with JD Granule or sorafenib were enrolled from December 2014 to March 2018. The primary endpoint was overall survival (OS). The secondary endpoints were progression-free survival (PFS) and safety. Propensity score matching (PSM) analysis was used to control for possible selection bias from the study group allocation process. RESULTS: Of the 325 patients included, 161 received JD Granule and 164 received sorafenib. No significant differences were found in OS or PFS among patients receiving JD Granule compared to sorafenib (P > 0.05). Median OS of the two study groups was 6.83 months (95% confidence interval [CI]: 5.83-9.47) in the group receiving JD Granule and 8 months (95% CI: 6.67-9.80) in the group receiving sorafenib, with half-, 1- and 2-year survival rates of 53.6%, 31.2% and 13.2% vs 60.1%, 35.5% and 14.2%, respectively. Even after PSM, the median survival time did not differ between the JD Granule group (9.03 months; 95% CI: 6.37-14.2) and the sorafenib group (7.93 months; 95% CI: 6.5-9.97), with comparable half-, 1- and 2-year survival rates. The most common adverse events (AEs) were diarrhea (13.7%) and fatigue (5.6%) in the JD Granule group, and hand-foot skin reaction (46.3%) and diarrhea (36.6%) in the sorafenib group. The JD Granule was more cost-effective than sorafenib treatment for advanced HCC. CONCLUSION Compared to sorafenib, JD Granule was more cost-effective and caused fewer AEs for the treatment of Chinese patients with advanced HCC.
