Uveitis is a blinding inflammatory disease that affects multiple structures within the eye, posing significant risks to patients' vision and mental health. Current treatments mainly involve glucocorticoids and immunosuppressants, which are associated with significant side effects, high relapse rates, and substantial costs. Recent research suggests that the gut microbiota may play a role in the development of uveitis through the gut-eye axis, with related metabolites also influencing disease progression. Modulating the gut microbiota or its metabolites could offer new therapeutic avenues for uveitis. This review explores the relationship between gut microbiota and various uveitis-associated diseases, such as systemic sarcoidosis, Vogt-Koyanagi-Harada syndrome, Behcet's disease, multiple sclerosis, and birdshot chorioretinopathy. It also discusses advancements in microbiota-related therapies, including probiotics and prebiotics, antibiotics, immunomodulators, phage therapy, and fecal microbiota transplantation. The aim is to provide a reference for the development of new therapies targeting specific microbial communities and genetic markers associated with uveitis, thereby promoting the realization of precision medicine.

Objective:To investigate the effect of autophagy inhibitor 3-methyladenine (3-MA) on uric acid (UA)-induced apoptosis of renal tubular epithelial cells.Methods:(1) Totally 24 SD rats were randomly divided into 4 groups: control group, treatment with 3-MA group, hyperuricemic nephropathy (HN) group, and HN+3-MA group, with 6 rats in each group. According to the body weight of the rats, adenine (100 mg/kg) and potassium oxonate (1 500 mg/kg) were mixed with distilled water to make a suspension, and the rats were given intragastrically once daily for consecutive 21 days to establish HN rat model. The control group and the 3-MA treatment group were fed an equivalent amount of distilled water. At the same time, the 3-MA treatment group and the HN+3-MA group were intraperitoneally injected with 3-MA (15 mg/kg), and the control group and HN group were intraperitoneally injected with an equal volume of saline once daily for 21 consecutive days. Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay (TUNEL) was used to observe renal cell apoptosis. Western blotting was used to detect the expression levels of cleaved caspase-3 and Bax, and immunofluorescence staining was used to detect the expression and localization of cleaved caspase-3 in renal tissue. (2) Human renal tubular epithelial cells (HK-2) were stimulated with UA (800 μmol/L), and cells were administrated with different concentrations of 3-MA or Beclin-1 small interfering RNA (siRNA). The apoptosis of renal tubular epithelial cells was detected by Western blotting and immunofluorescence staining.Results:Compared with the normal rats, the apoptosis of renal tubular epithelial cells in the HN group was significantly increased ( P<0.01), and the expression levels of cleaved caspase-3 and Bax were significantly up-regulated (both P<0.05). Compared with the HN group, the apoptosis of renal tubular epithelial cells in the HN+3-MA group was significantly decreased ( P<0.01). In addition, high level of uric acid could significantly increase the levels of apoptosis associated proteins in HK-2 cells (all P<0.05), and using different concentrations of 3-MA or transfecting with Beclin-1 siRNA could significantly reduce the expression of cleaved caspase-3 and Bax (all P<0.05). Conclusion:Autophagy plays an important role in uric acid-induced apoptosis of renal tubular epithelial cells. Inhibiting the excessive activation of autophagy may be a new strategy to prevent the progression of HN.

Objective To investigate the status quo of the off-label use in patients with major mental disorders in a tertiary psychiatric hospital and to analyze its relevant risk factors,so as to provide the basis for establishing the off-label use norm.Methods The data of inpatients with major mental disorders (schizophrenia,bipolar disorder and depression) were collected from electronic medical records system in the Affiliated Brain Hospital of Guangzhou Medical University (Guangzhou Huiai Hospital).The incidence and categories of off-label use were analyzed by descriptive analysis.The chi-square test and logistic regression analysis were used to analyze factors such as age,gender,diagnosis,the number of prescribed psychotropic drugs,physician title,etc.Results A total of 2 371 patients and 10 794 prescriptions were collected and analyzed.The incidence of off-label use was 80.43％ (1 907/2 371) and 42.46％ (4 583/10 794) in patients and prescriptions,respectively.The main categories and constituent ratio of off-label use were indications (89.16％,4 086/4 583),dosage (4.63％,212/4 583),population and age (0.31％,14/4 583),while there were 5.91％ (271/4 583) prescriptions contain 2 or more different categories.The off-label use was widespread among different types of psychotropic drugs,mental disorders and clinical departments.The risk factors were the number of prescribed psychotropic drugs (Wald=177.218,P＜0.01),the diagnosis of mental disorders (Wald=35.320,P＜0.01) and physician title (Wald=8.667,P=0.003).Conclusion Off-label use is common in patients in the tertiary psychiatric hospital,involving different kinds of psychotropic drugs,mental disorders and clinical departments.The primary category of off-label use is indications.

Objective To investigate the imaging characteristics and diagnostic value of tri-phase dynamic enhancement scan with CT for acute renal infarction. Methods The image features of CT plain scan and tri-phase dynamic enhancement scan of 10 patients (19 sides) with acute renal infarction were retrospectively analyzed, and the CTA expression of 6 patients were observed. Results Fourteen acute renal infarction lesions of 10 cases were diagnosed. The CT scan showed there were 4 cases with enlargement of kidney, and the other 6 cases were of no abnormality. The tri-phase enhancement CT scan showed there were 6 cases of unilateral renal infarction and 4 cases of bilateral renal infarction, which totally involving 14 sides. The acute renal infarction lesions lacked of high density region in the corticomedullary in cortical phase, and there were wedge-shaped hypodense area, even low density of full kidney in parenchymal phase and pyelographic phase. The a-cute renal infarction lesions were revealed better in parenchymal phase and pyelographic phase than in cortical phase. Six cases of CTA re-vealed the responsible vessels of renal infarction lesions and the other vascular diseases. Conclusion CT tri-phase dynamic enhancement scan has important value in the diagnosis of acute renal infarction, and CTA can identify the responsible vessels of renal infarction lesions.

To determine the content of dendrobine in Dendrobium nobile from different harvest times and plant parts, to research the inherent rule about it. GC with internal standard was used to determine. The content of dendrobine had significant differences in different periods and parts. The dendrobine content is higher in four-year root than in three-year root. The dendrobine content in the upper segment of stem is the highest, secondly is in the middle seg-ment, and in the low segment is the lowest. This offered evidence to determine the most appropriate harvest time and fair use of different parts for D.nobil.

Objective To evaluate the effect of applying modified clinical pathway management model in psychiatric nursing practice teaching.Methods Totally 196 nursing students joining in the psychiatric nursing clinical practice were divided into control group (n=102) and intervention group (n=94), according to their internship time.The control group followed the traditional teaching model, while the intervention group received training based on the modified clinical pathway model, in which the students were involved in to specify the training plan and generate the sequence and timing of actions necessary to achieve goals.The examination, mutual behavior rating and total satisfaction investigations’ results were compared between the two groups at the end of the internship.Results Both the exam scores and the satisfactions in the intervention group were significantly higher than that in the control group (P<0.01).Two factors were extracted by exploratory factor analysis, factor one included:teaching skills, professional moral, level of expertise, theoretical score, work attitude, operating score; factor two included: teaching management capability, lecture score, behavioral norms, satisfaction evaluation ( student to teacher ) .Conclusions The application of clinical pathway in psychiatric nursing practice can standardize and explicit training protocol, improve the effect of internship.It is a kind of teaching model worth spreading.
