Retinitis pigmentosa （RP） is the most common hereditary blinding eye disease in clinical practice， with the pathogenesis remaining unclear. Patients experience progressive apoptosis of retinal photoreceptor cells， accompanied by degeneration of retinal pigment epithelium （RPE） cells. Current Western medical treatments mainly focus on gene therapy and stem cell transplantation， showing limited efficacy. In contrast， clinical observations have confirmed the therapeutic effects of traditional Chinese medicine （TCM） treatments. Establishing an RP animal model that aligns with the diagnostic features of both TCM and Western medicine could help combine the strengths of both approaches， thereby broadening the treatment options for RP. This study categorizes and summarizes the existing RP animal models in terms of classification， types， inheritance patterns， and alignment with clinical manifestations. It is found that current RP models are primarily derived from natural animal models such as RD mice and RCS rats， transgenic animal models like RPE-65 knockout mice and rhodopsin gene knockout mice， and chemically induced models such as those created by monochromatic light exposure or N-ethyl-N-nitrosourea （ENU） administration. These three categories of models focus more on detecting RP-related histopathological， molecular biological， and cellular immunological indicators， but offer limited observation of the overall characteristics of the disease and lack insight into syndrome differentiation. Although RP is a congenital genetic disease， its progression is influenced by acquired factors such as environment， constitution， emotions， and care. Current models do not fully capture the characteristics of this disease. Therefore， establishing an RP animal model based on the diagnostic features of both TCM and Western medicine will have significant implications for future experimental and clinical research.

Objective:To investigate the gene transcription level changes in the amygdala of social isolation rearing models of schizophrenia to determine the pathogenic genes and their related pathways of schizophrenia.Methods:A total of 29 3-week-old SPF C57BL/6J male mice were randomly divided into control group ( n=16) and model group ( n=13); 4 mice were raised in each transparent mouse cage in the control group, and 1 mouse was raised in each transparent mouse cage in the model group; mice in each cage could see their surrounding mice but could not touch each other. Mice in both groups were fed for 4 weeks and then subjected to open field experiment, pre-pulse inhibition experiment and new object recognition experiment within one week. After the experiment, mice were sacrificed by spinal dislocation, and the amygdala was taken for transcriptome sequencing. The topGO software was used for gene ontology (GO) functional enrichment analysis of differentially expressed genes (DEGs), and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was performed using KEGG database. Results:(1) Animal experiment: compared with the control group, the model group had significantly increased movement distance in the open field experiment ([1 239.20±106.35] m vs. [1 845.53±143.65] m, t=3.464, P=0.002), significantly decreased activity time in the central region 5 min before experiment ([13.15±1.41] s vs. [8.47±1.19]) s, t=2.464, P=0.020). Compared with the control group, the model group had significantly lower percentage of deficient prepulse inhibition (PPI) of 78 dB ([22.28±1.53] % vs. [14.59±2.75] %, t=2.629, P=0.013), and deficient PPI of 88 dB ([32.83±3.39] % vs. [18.44±3.07] %, t=3.081, P=0.005). Compared with the control group, the model group had significantly decreased ratio of time exploring new objects/time exploring former objects ([80.5±2.2]% vs. [71.0±3.6]%, t=2.356, P=0.026). (2) Bioinformatics analysis: a total of 96 DEGs were found, of which 42 were with up-regulated expressions ( Th, Crlf1, etc.), and 54 were with down-regulated expressions ( Prkcd, etc.). Th and Crlf1 were positively correlated ( r=0.940, P=0.018). GO enrichment results suggested that DEGs were enriched in projection function of plasma membrane boundary cells, neuronal differentiation, and cell apoptosis. KEGG enrichment results suggested that DEGs were enriched in WNT signaling pathway, apoptosis pathway and tyrosine metabolism pathway. Protein network interaction analysis suggested that Wnt6, Tcf712, Pitx2, Tcf7 and Cd4 were key proteins. Conclusion:DEGs such as Th, Prkcd, Lrrc74b, Fadd, Wnt6, Ror2, Notum, and Tcf7l2, and their related signaling pathways may be related to schizophrenia in the amygdala of social isolation rearing mice.

Objective To cross-cultural adapt and test the reliability and validity of Humanistic Relationship Experience Scale (HRES) made by Boscart. Methods Cross-culture Adaptation was carried out by following American Academy of Orthopaedic Surgeons Evidence Based Medicine Committee (AAOS). A convenience sampling was conducted among 180 patients with chronic disease, and then assessed the reliability and validity of HRES. The internal consistency coefficient and the test-retest were used to assess the reliability of HRES, and the content validity index (CVI) and construct validity were used to assess the validity of HRES. Results In order to understand the purpose and content of the scale easily, the Chinese version title of HRES was revised to"Nursing Humanistic Care Experience Scale-Noninfectious Chronic Disease Patients Version (NHCES-NCDP)" after soliciting experts′ advice. The CVI of the scale was 1;factor analysis got three factors, which could explain 67.897％of the total variance. A 0.965 Cronbachαof total scale was obtained, and for each dimension range was 0.876-0.948;the test-retest reliability was 0.710 for the overall scale. Conclusion NHCES-NCDP is reliable and valid, which can be used to assess the experience of nursing humanistic care for patients with chronic diseases, and to explore nurses′implementation of nursing humanistic care.

Objective To evaluate the ability of diffusion-weighted imaging (DWI)in differentiating pancreatic carcinoma from chronic lump type pancreatitis. Methods Totally 38 cases of pancreatic cancer, 9 cases of chronic lump type pancreatitis, 15 cases of normal patients underwent DWI. DWI with b value＝0, 500, 1 000 s/mm2 was performed twice. Apparent diffusion coefficient (ADC) was measured by analysis of imagines of ADC. Results The mean ADC value of 38 subjects with pancreatic carcinoma was (1.411± 0.101)×10-3 mm2/sec, the mean ADC value of 9 subjects with lump type pancreatitis was (1.053±0.113) ×10-3 mm2/sec, and the mean ADC value of normal pancreas subjects was (1.245±0.112)×10-3 mm2/s. The difference between the three groups were statistically significant (P＜0.05). Conclusions DWI may have the clinical potential to differentiate chronic lump type pancreatitis from pancreatic carcinoma.
