This paper introduces the academic characteristics of Professor ZHANG Ren in treatment with acupuncture for refractory eye diseases in modern times, guided by "homotherapy for heteropathy" (same therapy for different diseases sharing the same pathogenesis). The refractory eye diseases in modern times include a variety of conditions such as glaucoma, macular degeneration, diabetic retinopathy, high myopia and its complications, dry eye, cortical visual impairment and genetic eye diseases. The same therapy is used because these diseases share the similar location and pathogenesis. Professor ZHANG optimizes the methods of acupoint selection and provides the comprehensive prescriptions, "basic prescription, prescription based on disease differentiation, and supplementary prescription". A variety of acupuncture manipulation techniques are operated in clinical practice, such as compound needling methods, penetration needling, manipulations for promoting qi movement and conducting qi flow. "Early, regular and persistent" treatment is the common requirement with "the same acupoints, the same prescription and the same acupuncture method" as well as at "the same time". It is also proposed that the treatment should be provided flexibly according to the different symptoms, "identifying the differences within similarities".

Objective To investigate the effect of laser engraving personalized nasal patch applied to patients with nasal catheter indentation.Methods A total of 124 patients who underwent esophageal cancer surgery in the First Hospital of Lanzhou University from February 2022 to February 2023 and required indwelling nasal catheter were selected as study objects,and were divided into experimental group and control group according to random number table method,with 62 cases in each group.The control group used conventionally cut nasal patches to fix the nasal catheters,and the experimental group used laser engraved personalized nasal patches.Catheter displacement or slippage under the fixation device,nasal patch rolled edges and number of replacement,nasal medical device-related pressure injury,medical adhesive-related skin lesions and patients'comfort were observed in two groups.Results The rate of catheter displacement,number of rolled edges of nasal patches and numbers of replacement in experimental group were significantly lower than those in control group(P<0.05).The incidence of nasal mucosal indentation,nasal pain,nasal pressure injury and medical adhesive related skin lesions in experimental group were significantly lower than those in control group(P<0.05).The comfort of patients at the physiological level of experimental group was significantly better than that of control group(P<0.05).Conclusion Laser engraved personalized nasal patches can reduce the frequency of clinical nasal catheter displacement,nasal patch rolled edges and number of replacement,reduce the occurrence of nasal medical device related pressure injuries and medical adhesive-related skin lesions,and increase patients'comfort.

ObjectiveThe human angiotensin converting enzyme2 （hACE2） transgenic mouse model was used to clarify the antiviral efficacy of BD-77 against a novel coronavirus SARS-CoV-2 and explore the action mechanism of BD-77 against SARS-CoV-2. MethodSARS-CoV-2 Omicron and Delta variant strains-infected VeroE6 cell models were established and administered with BD-77 to observe the antiviral effect of BD-77 in vitro. A kit was used to detect the effect of BD-77 in vitro on the binding of spike S protein of SARS-CoV-2 virus （Delta/Omicron） to angiotensin converting enzyme2 （ACE2）. Chromatography was adopted to detect the binding of BD-77 to the S protein and N protein of the novel coronavirus. hACE2 transgenic C57BL/6 mice were divided into a blank control group， SARS-CoV-2 infection group， BD-77 administration groups of 37.5 mg·kg^-1 and 75 mg·kg^-1， with eight mice in each group. The pneumonia model of SARS-CoV-2-infected hACE2 transgenic mice was built to observe the survival of the mice， detect the virus titer of the lung tissue of the mice， and observe the lesions in the lung tissue. ResultBD-77 had a certain inhibitory effect on Omicron and Delta variant strains in vitro， with median inhibitory concentration （IC₅₀） of 526.3 mg·L^-1 and 653.0 mg·L^-1， respectively. BD-77 had no significant inhibitory effect on the binding of the S protein of WT， Omicron， and Delta variant strains of SARS-CoV-2 to ACE2 and had no binding effect with the S protein and N protein of the novel coronavirus. No mice in the blank group died， while the mortality rate of SARS-CoV-2-infected mice was 75%. There was a large amount of virus replication in the lung tissue of the mice and large areas of inflammatory infiltration in the lung tissue and interstitium. Compared with the model group， BD-77 administration groups of 37.5 mg·kg^-1 and 75 mg·kg^-1 could reduce the mortality of mice， significantly lower the virus titer in the lung tissue of mice （P<0.05）， and improve lung lesions. ConclusionBD-77 demonstrated significant inhibitory effects against SARS-CoV-2 virus in vitro and in vivo. However， its mechanism of action did not involve direct inhibition of the virus itself or intervention in the virus-host binding process. This finding suggests that the mechanism of action of BD-77 needs to be thoroughly investigated and elucidated by further experiments.

【Objective】 To investigate the anemia status of infants and toddlers aged 6 - 24 months in Linxia Hui Autonomous Prefecture, Gansu Province, and to comprehensively evaluate the differences in feeding behaviors between anaemic and normal children through the infant and child feeding index (ICFI) and feeding knowledge scores, so as to provide reference for the guidance of infants and young children feeding in ethnic minority areas and the promotion of children′s growth and development. 【Methods】 Taking infants and young children aged 6 - 24 months in Linxia Prefecture as the study subjects, a multi-stage random sampling method was used to select children who met the requirements from 5 townships and 5 villages in 7 counties in 2019 and 2020.Periphral blood samples were collected to test the level of hemoglobin, so as to determine the anemia status.Meanwhile, physical examination was performed and a questionnaire survey of guardians was conducted to analyze the association betweenanaemia and feeding patterns 【Results】 A total of 3 901 infants and children were included in this study, of whom 729 (18.70%) were anaemic, with a mean ICFI score of 12.56±2.70 and a mean feeding knowledge score of 1.97±1.01.There was no statistically significant association of low feeding knowledge score and low ICFI with anaemia after adjusting for confounders (P>0.05), Unqualified meat addition in ICFI was a risk factor for anaemia (OR=1.355, P=0.042), while non-bottle feeding in the past 24 hours (OR=0.762, P=0.021), and breastfeeding in the past 24 hours of infants and toddlers aged 12 - 24 months (OR=0.228, P=0.018) were protective factor for anemia in infants and toddlers aged 12 - 24 months. 【Conclusions】 The average prevalence of anemia in infants and toddlers aged 6 - 24 months in Linxia Hui Autonomous Prefecture of Gansu Province is high, but the level of infant feeding and the level of feeding knowledge of caregivers are low.Early adherence to breastfeeding, timely addition of supplementary food, and more comsumpution of meat for children are conducive to preventing anemia.

Background and purpose:Heterogeneous nuclear ribonucleoprotein K(hnRNPK)is an RNA special binding protein that participates in regulating the expression of related genes and protein translation.It has been linked to the malignant occurrence and development of various tumors,but its role in breast cancer remains unclear.The aim of this study was to investigate the effects of hnRNPK on ferroptosis in breast cancer cells and the underlying mechanisms.Methods:Based on The Cancer Genome Atlas(TCGA)and Gene Expression Omnibus(GEO)databases,hnRNPK expression in breast cancer tissues and normal tissues and its relationship with clinical prognosis were analyzed by bioinformatics.We detected hnRNPK expression in breast cancer cells and tissues using real-time quantitative reverse transcription polymerase chain reaction(qRT-PCR),Western blot,and immunohistochemistry staining diagnosis methods.MCF-7 and MDA-MB-231 breast cancer cells were transfected with siRNA,and divided into control group(control),empty body group(NC),and interference vector group(si-hnRNPK).Cell proliferation was detected by cell counting kit-8(CCK-8)and plate clone formation assays.RNA-seq analysis was applied to explore potential targeted biological functions and signaling pathways affected by hnRNPK.Additionally,we investigated the impact of hnRNPK on ferroptosis phenotype using Western blot and commercial kits for reactive oxygen species(ROS),malondialdehyde(MDA),glutathione(GSH),and Fe2+,ferroptosis inhibitor(ferrostatin-1,Fer-1)was used to detect the rescue effect of hnRNPK knockdown on ferroptosis.The impact of hnRNPK on the expressions of Wnt/β-catenin pathway-related proteins were determined by Western blot.Results:The bioinformatics analyses indicated hnRNPK was upregulated in breast cancer tissues(P＜0.01),and the overall survival of patients in the high expression group was poorer compared with those in the low expression group(P＜0.05).hnRNPK was highly expressed in breast cancer tissues and cells,and knocking down hnRNPK weakened the proliferation ability of breast cancer cells(P＜0.05).The RNA-seq analysis showed that hnRNPK was significantly enriched in ferroptosis,apoptosis,and the Wnt/β-catenin signaling pathway.Knocking down hnRNPK promoted ferroptosis in breast cancer cells by inducing lipid ROS and MDA,as well as Fe2+accumulation(P＜0.05).Interestingly,the ferroptosis inhibitor ferrostatin-1(Fer-1)reversed the promotive effect of hnRNPK knockdown on ferroptosis(P＜0.05).Downregulation of hnRNPK led to a decrease in the expressions of β-catenin and c-Myc in the Wnt/β-catenin signaling pathway,while expressions of CK1α,APC and the GSK-3β complex were elevated(P＜0.05).Conclusion:hnRNPK is highly expressed in breast cancer,and knocking down hnRNPK promotes ferroptosis in breast cancer cells by inhibiting the Wnt/β-catenin signaling pathway,thereby suppressing the malignant progression of breast cancer.

So as to preliminary exploration the intestinal flora characteristics of T2DM in the Dongxiang group.The findings of this study provide a theoretical basis for the prevention and control of T2DM in Dongxiang group in the future.

Objective To investigate the effects of lipopolysaccharide (LPS) on human pulmonary vascular endothelial cells (HPVECs) cytoskeleton and perform biological analysis of the microRNA (miRNA) spectrum. Methods The morphology of HPVECs was observed by microscope, the cytoskeleton by FITC-phalloidin staining, and the expression of VE-cadherin was detected by immunofluorescence cytochemical staining; the tube formation assay was conducted to examine the angiogenesis, along with cell migration test to detect the migration, and JC-1 mitochondrial membrane potential to detect the apoptosis. Illumina small-RNA sequencing was used to identify differentially expressed miRNAs in NC and LPS group. The target genes of differentially expressed miRNAs were predicted by miRanda and TargetScan, and the functional and pathway enrichment analysis was performed on Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). Further biological analysis of related miRNAs was carried out. Results After the LPS got induced, the cells became round and the integrity of cytoskeleton was destroyed. The decreased expression of VE-cadherin was also observed, along with the decreased ability of angiogenesis and migration, and increased apoptosis. Sequencing results showed a total of 229 differential miRNAs, of which 84 miRNA were up-regulated and 145 miRNA were down-regulated. The target gene prediction and functional enrichment analysis of these differential miRNA showed that they were mainly concentrated in pathways related to cell connection and cytoskeleton regulation, cell adhesion process and inflammation. Conclusion In vitro model of lung injury, multiple miRNAs are involved in the process of HPVECs cytoskeleton remodeling, the reduction of barrier function, angiogenesis, migration and apoptosis.
