Objective:To examine the postoperative morphological changes in outer retinal wave-like changes (ORC) in eyes with rhegmatogenous retinal detachment (RRD).Methods:A retrospective clinical study. From March 2020 to March 2024, 64 eyes of 64 RRD patients diagnosed at The Second Affiliated Hospital of Zunyi Medical University were included. The cohort included 39 males (39 eyes) and 25 females (25 eyes), with a mean age of (45.3±15.7) years and a mean retinal detachment duration of (16.6±13.5) days. Macular involvement was observed in 51 eyes. Scleral buckling surgery (SB), pars plana vitrectomy (PPV), and SB+PPV were performed in 17, 44, and 3 eyes respectively. Best corrected visual acuity (BCVA) and spectral domain optical coherence tomography examinations were performed in all affected eyes. BCVA examination was performed using the standard logarithmic visual acuity chart, and the visual acuity was converted to logarithm of the minimum angle of resolution (logMAR) during statistics. Combined with the ORC situation before the operation, the morphological repositioning of outer retinal folds (ORF) after the operation was classified into types Ⅰ, Ⅱ and Ⅲ. One week and one and three months after the operation, relevant examinations were performed using the same equipment and methods as before the operation. The structural characteristics of ORC and the morphology of ORF after surgery were observed. The comparison between groups was conducted using the independent sample t test or the Mann-Whitney U test. Results:Among the 64 eyes, preoperative ORC was present in 46 eyes (71.9%, 46/64) and absent in 18 eyes (28.1%, 18/64). The 18 eyes without ORC had retinal detachment durations of either ≤4 days or ≥42 days. Postoperatively, ORF was observed in 51 eyes (79.7%, 51/64) and absent in 13 eyes (20.3%, 13/64). Among the 51 eyes with macular holes involved, 24 eyes (47.1%, 24/51) had ORF after the operation and 27 eyes (52.9%, 27/51) had no ORF. Among the 46 and 18 eyes with and without ORC, the ORF after surgery was 28 (60.9%, 28/46) and 1 (5.6%, 1/18) eyes, respectively. There was a statistically significant difference in the reduction rate of ORF after surgery between eyes with and without ORC ( χ2=15.974, P<0.001). Among the 46 eyes with ORC, the proportions of ORF to types Ⅰ, Ⅱ and Ⅲ after surgery were 24 (52.2%, 24/46), 20 (43.5%, 20/46), and 2 (4.3%, 2/46) eyes, respectively. There was no statistically significant difference in the incidence of ORF after different surgical methods in eyes with ORC ( P>0.05). One week and one month after the surgery, the logMAR BCVA of the affected eyes with and without ORF was 0.97±0.47, 0.69±0.34 and 0.85±0.32, 0.54±0.21, respectively. The BCVA of those without ORF was better than that of those with ORF, but the differences were not statistically significant ( t=0.237, 0.408; P>0.05). Conclusions:The occurrence of ORC in RRD eyes has a certain relationship with the time of retinal detachment. For RRD eyes with ORC before the operation, the repositioning morphology after the operation is more likely to show changes in ORF. The transformation from ORC to ORF after ORC surgery has no correlation with the surgical method.

Acta Medicinae Universitatis Scientiae et Technologiae Huazhong 2024;53(5):621-628
Objective To investigate the effect of long non-coding RNA growth arrest-specific transcript 5(lncRNA GAS5)on lung tissue cell apoptosis in acute lung injury(ALI)rats via regulation of the miR-452-5p/myeloid cell leukemia sequence 1(Mcl-1)pathway.Methods SD rats were randomly separated into 6 groups(10 in each group):control group,model group,pUC57 lncRNA GAS5 group,miR-452-5p antagonist group,pUC57 NC+miR-452-5p NC group,and pUC57 lncRNA GAS5+miR-452-5p agonist group.The ALI model was constructed via the intraperitoneal injection of lipopolysaccharide in the model group and drug intervention group,whereas the control group rats were intraperitoneally injected with an equal dose of physio-logical saline.At the same time,the intervention was performed,and the lung function of the rats was subsequently meas-ured.The forced vital capacity(FVC),forced expiratory volume in 0.3 second(FEV0.3)/FVC,and tidal volume(VT)were com-pared among the groups.HE staining was used to observe pathological damage in the lung tissue,and the degree of damage was evaluated via the Holfbauer score.An enzyme-linked immunosorbent assay(ELISA)was used to measure the levels of bronchoal-veolar lavage fluid(BALF)and the serum inflammatory factors interleukin-18 and IL-1β in the rats.Immunoblotting was used to detect the expression of pyroptosis-related indicator proteins[(GSDMD),nucleotide binding oligomeric domain-like receptor protein 3(NLRP3),cysteine-containing aspartate-specific protease(Caspase-1),and Caspase-11]and Mcl-1 in rat lung tissue.Real-time fluorescence quantitative PCR was used to detect the expression of lncRNA GAS5 and miR-452-5p in rat lung tissue.A dual-luciferase reporter gene experiment was performed to validate the targeted regulation of miR-452-5p by lncRNA GAS5 in rat alveolar epithelial cell L2.Results Compared with those in the control group,the FVC,FEV0.3/FVC,expression of lncRNA GAS5,expression of Mcl-1 protein and mRNA in the model group decreased(P<0.05),and the VT,Holfbauer score,IL-18 and IL-1β levels,GSDMD,NLRP3,Caspase-1 and Caspase-11 protein expression,and miR-452-5p expression were elevated(all P<0.05).Compared with those in the model group,the FVC,FEV0.3/FVC,expression of Mcl-1 protein and mR-NA in the pUC57 lncRNA GAS5 group and the miR-452-5p antagonist group were increased(all P<0.05),and the VT,Holf-bauer score,IL-18 and IL-1β levels,GSDMD,NLRP3,Caspase-1 and Caspase-11 protein expression,and miR-452-5p expression were reduced(all P<0.05).There was no obvious difference in various indicators in the pUC57-NC+miR-452-5p-NC group(all P>0.05).Compared with those in the pUC57 lncRNA GAS5 group,the FVC,FEV0.3/FVC,expression of Mcl-1 protein and mRNA in the pUC57 lncRNA GAS5+miR-452-5p agonist group decreased(all P<0.05),and the VT,Holfbauer score,IL-18 and IL-1β levels,GSDMD,NLRP3,Caspase-1 and Caspase-11 protein expression,and miR-452-5p expression were elevated(all P<0.05).Conclusion lncRNA GAS5 can promote Mcl-1 expression by down-regulating miR-452-5p,thereby inhibiting the in-flammatory response and lung tissue cell pyroptosis in ALI rats,ultimately reducing lung injury and improving lung function.

This study aimed to explore the effect of miR-23b-3p on the differentiation of goat intramuscular preadipocytes, and to confirm whether miR-23b-3p plays its roles via targeting the PDE4B gene. Based on the pre-transcriptome sequencing data obtained previously, the miR-23b-3p, which was differentially expressed in goat intramuscular adipocytes before and after differentiation, was used as an entry point. real-time quantitative-polymerase chain reaction (qPCR) was used to detect the expression pattern of miR-23b-3p during the differentiation of goat intramuscular preadipocytes. The effects of miR-23b-3p on adipose differentiation and adipose differentiation marker genes were determined at the morphological and molecular levels. The downstream target genes of miR-23b-3p were determined using bioinformatics prediction as well as dual luciferase reporter assay to clarify the targeting relationship between miR-23b-3p and the predicted target genes. The results indicated that overexpression of miR-23b-3p reduced lipid droplet accumulation in goat intramuscular adipocytes, significantly down-regulated the expression levels of adipogenic marker genes AP2, C/EBPα, FASN, and LPL (P < 0.01). In addition, the expressions of C/EBPβ, DGAT2, GLUT4 and PPARγ were significantly downregulated (P < 0.05). After interfering with the expression of miR-23b-3p, lipid droplet accumulation was increased in goat intramuscular adipocytes. The expression levels of ACC, ATGL, AP2, DGAT2, GLUT4, FASN and SREBP1 were extremely significantly up-regulated (P < 0.01), and the expression levels of C/EBPβ, LPL and PPARγ were significantly up-regulated (P < 0.05). It was predicted that PDE4B might be a target gene of miR-23b-3p. The mRNA expression level of PDE4B was significantly decreased after overexpression of miR-23b-3p (P < 0.01), and the interference with miR-23b-3p significantly increased the mRNA level of PDE4B (P < 0.05). The dual luciferase reporter assay indicated that miR-23b-3p had a targeting relationship with PDE4B gene. MiR-23b-3p regulates the differentiation of goat intramuscular preadipocytes by targeting the PDE4B gene.

The purpose of this study was to clone and characterize the ZFP36L1 (zinc finger protein 36-like 1) gene, clarify its expression characteristics, and elucidate its expression patterns in different tissues of goats. Samples of 15 tissues from Jianzhou big-eared goats, including heart, liver, spleen, lung and kidney were collected. Goat ZFP36L1 gene was amplified by reverse transcription-polymerase chain reaction (RT-PCR), then the gene and protein sequence were analyzed by online tools. Quantitative real-time polymerase chain reaction (qPCR) was used to detect the expression level of ZFP36L1 in intramuscular preadipocytes in different tissues and adipocytes of goat at different differentiation stages. The results showed that the length of ZFR36L1 gene was 1 224 bp, and the coding sequence (CDS) region was 1 017 bp, encoding 338 amino acids, which was a non-secretory unstable protein mainly located in nucleus and cytoplasm. Tissue expression profile showed that ZFP36L1 gene was expressed in all selected tissues. In visceral tissues, the small intestine showed the highest expression level (P < 0.01). In muscle tissue, the highest expression level was presented in longissimus dorsi muscle (P < 0.01), whereas the expression level in subcutaneous adipose tissue was significantly higher than that in other tissues (P < 0.01). The results of induced differentiation showed that the expression of this gene was up-regulated during adipogenic differentiation of intramuscular precursor adipocytes (P < 0.01). These data may help to clarify the biological function of the ZFP36L1 gene in goat.

Under the background of " Internet+ medical treatment" and the continuous deepening of face recognition technology research, the face recognition industry has continued to mature, and face recognition has been initially applied in medical fields such as hospital management, auxiliary medical care, and epidemic prevention and control. At the same time, face recognition technology brings problems including error risk, technical cracking risk, privacy risk, equality risk, abuse risk, and other issues in practice, which seriously threaten the personal and property rights and interests of the public. On the basis of summarizing the specific application direction of face recognition technology in hospitals, the authors sorted out the legal regulation of face recognition in China, and proposed that it should be based on technology research and development, strengthen the " gatekeeper" responsibility of medical institutions, improve legal system and recommendations for strengthening judicial leadership in order to improve the legal regulations of face recognition technology, reduce the risk of infringement by medical institutions in the application of face recognition technology, and protect the legitimate rights and interests of citizens.

Objective:To study the influence of the choice of main diagnosis on diagnosis-related groups(DRG) grouping and weight change, by taking cerebral infarction as the entry point.Methods:From January 1, 2019 to March 31, 2019, 331 patients in three DRG groups(BR25, BR23, BR21) with cerebral infarction were selected. The original group was used as the control group; the main diagnosis was exchanged with the first other diagnosis, then DRG group was used as the experimental group. The difference of the number of cases and weight between the two groups was analyzed.Results:41.4%(137/331) of the patients in the experimental group were enrolled in BZ11 with other neurological disorders associated with important comorbidities and comorbidities, and 82.5%(273/331) patients′ weight increased after diagnostic conversion.Conclusions:Choosing other diagnosis as the main diagnosis may change the weight of the disease and affect the corresponding disease benefit. In order to prevent downcoding, DRG grouping should be detailed, and DRG payment should consider how to reflect the value of difficult cases; for upcoding behavior, medical insurance center and relevant medical institutions should check the correctness of coding, and monitor in place.
