Objective: To investigate the relationship between HLA-DR4/1 subtypes and T cell responses to type Ⅱ collagen or anti-CⅡ263-272 antibodies. Methods: Peripheral blood mononuclear cells and sera were obtained from 70 rheumatoid arthritis (RA) patients. T cell proliferative responses to CⅡ263-272 were evaluated by 3H thymidine incorporation assay. Antibodies specific to CⅡ263-272 were determined by ELISA. HLA-DR4/1 subtypes were analyzed by PCR-SSP. Results: In HLA-DR4/1 positive group, T cell proliferative responses to CⅡ263-272 were observed in 55.6% RA patients and anti- CⅡ263-272 antibodies were present in 66.7% RA patients. In HLA-DR4/1 negative group, T cell proliferative responses to CⅡ263-272 were observed in 30.3% RA patients and anti-CⅡ263-272 antibodies were present in 34.8% RA patients. The number of positive antibodies to CⅡ263-272 or T cell proliferative responses to CⅡ263-272 in HLA-DR4/1 positive group were higher than in negative group. Conclusion: There is a relationship between HLA-DR4/1 subtypes and T cell responses to CⅡ263-272 or anti-CⅡ263-272 antibodies.

Objective To investigate the prevalence and significance of anti-?2-glycoprotein Ⅰ (anti-?2-GPⅠ) in patients with systemic lupus erythematosus (SLE). Methods Anti-?2-GPⅠ level was determined in 112 SLE patients, 40 patients with rheumatoid arthritis (RA), 30 patients with Sj?gren′s syndrome (SS) and 40 healthy individuals by enzyme-linked immunosorbent assay (ELISA). The laboratory and clinical features (thrombosis, fetal loss, etc) were analyzed retrospectively from the clinical database. Results Sensitivities of anti-?2-GPⅠ were 21.4%, 15.0%, 6.7% in SLE, RA and SS, respectively. The specificity of anti-?2-GPⅠ was 88.6% in SLE. Correlations between thrombosis and titers of ACL-IgG/IgM and anti-?2-GPⅠ were statistically significant. No association was found between anti-?2-GPⅠ and other clinical and laboratory features. Conclusion The results indicate that anti-?2-glycoprotein Ⅰ antibodies are common and may play a role in SLE with thrombosis. Combination of ACL and anti-?2-GPⅠ can facilitate the diagnosis of SLE with thrombosis.

Objective:
Predefining the most effective treatment for patients with depressive disorders remains a problem. We will examine the differential brain regions of gray matter (GM) in major depressive disorder (MDD) patients and the relationship between changes in their volume and the efficacy of early antidepressant treatment using magnetic resonance imaging (MRI).
Methods:
159 never-medicated patients with first-episode MDD and 53 normal control subjects (NCs) were enrolled. The brains were scanned by MRI and measured with the 17-item Hamilton Depression Rating Scale (HAMD-17) at baseline and after 2 weeks of treatment with selective serotonin reuptake inhibitor (SSRI)s, and the non-responder group and responder group were obtained. The patients were analyzed by voxel-based morphological (VBM) and SPSS software. Receiver operator characteristics (ROC) analysis was performed for the difference between the responder group and the non-responder group in the differential brain regions, and Pearson correlations were computed between volume size and HAMD score reduction rate.
Results:
Smaller GM volume of the right superior temporal gyrus (STG), and the orbital parts of the right medial frontal gyrus and right inferior frontal gyrus were observed in MDD versus the NCs. The non-responder group demonstrated a significant volume reduction at the right STG compared with the responders, but no corresponding change in orbital part of right medial frontal gyrus and right inferior frontal gyrus. ROC analysis showed that Accuracy=71.2%. There was a positive correlation between the STG gray matter volume and the HAMD-17 score reduction rate (r=0.347, p=0.002).
Conclusion
The study results confirmed the local changes in brain structure in MDD and may initially predict the early treatment response produced by SSRIs as antidepressants.

OBJECTIVE: Although the pathogenesis of depression remains unclear, C-reactive protein (CRP) levels are commonly elevated in depressed patients. Thus, CRP single-nucleotide polymorphisms (SNPs) that influence CRP levels may be associated with depression. In the present study, we explored whether CRP SNPs are related to depressive symptoms and antidepressants efficacy in Han Chinese patients.METHODS: We analyzed data from 440 patients with first-episode depression. We obtained genome CRP SNPs, scores of the 17-item Hamilton Rating Scale for Depression 17 (HAMD17) and its four-factor at baseline and after 6 weeks. Quantitative trait analysis was performed using UNPHASED software and curative effects were analyzed using SPSS software.RESULTS: Male patients with SNP rs1800947G exhibited lower insomnia scores and rs2794521CC exhibited lower scores of anxiety/ physical symptoms, total HAMD17 score. Female patients with rs2794521TT exhibited higher scores of insomnia and lower antidepressants efficacy.CONCLUSION: CRP SNPs rs1800947 and rs2794521 may be associated with depressive symptoms in patients with depression in a sex-specific fashion. Furthermore, rs2794521 may be a predictor of the efficacy of antidepressants in female patients.

Objective:
To investigate the relationship between prostate volume and postoperative stress urinary incontinence (SUI) in the elderly benign prostatic hyperplasia (BPH) patients following holmium laser enucleation of the prostate (HoLEP).
Methods:
A retrospective analysis was performed on clinical data of 110 elderly (age ≥ 60 years) BPH patients who underwent HoLEP in Grand Hospital of Jincheng in Shanxi between 2014 and 2018. In these patients, preoperative transrectal ultrasonography revealed that the prostate volume was 21-198(74.53 ± 31.26) ml. According to prostate volume, the patients were allocated to large prostate volume group (prostate volume ≥ 80 ml), intermediate prostate volume group (40 ml < prostate volume < 80 ml) and small prostate volume group (prostate volume ≤ 40 ml). All patients underwent the HoLEP, the incidence of postoperative SUI was compared among the three groups after withdrawal of stenting catheters.
Results:
After HoLEP, 74 patients were uneventful, while 36 patients experienced the postoperative SUI. No perpetual SUI patient was found after follow-up for 1 week to 6 months. The incidence of postoperative SUI after HoLEP was positively correlated with prostate volume (
8.Research progress of extracellular matrix in age-related macular degeneration
International Eye Science 2024;24(7):1073-1077
Age-related macular degeneration(ARMD)is the leading cause of blindness in the elderly. Studies have shown that the regulation disorder of extracellular matrix(ECM)is one of the important characteristics of ARMD, and its damage can be sustained throughout the disease course. Additionally, various cell types participate in the formation and abnormal deposition of ECM under the control of multiple signals. Subsequently, they transmit signals that regulate adhesion, migration, proliferation, apoptosis, survival or differentiation, which lead to the destruction of the retinal and choroidal microenvironment, immune dysfunction, infiltrative inflammatory cell differentiation, neovascularization and epithelial mesenchymal transformation, and ultimately lead to subretinal fibrosis, scarring and severe visual impairment in advanced ARMD. Therefore, increasing attention has been paid to the role of ECM in ARMD in recent years. This article reviews the relationship between retinal ECM and ARMD and the role between ECM and various types of cells in ARMD, hoping to provide guidance for the research direction of ARMD treatment.

Objective:To study the effect of ZhuJing pill variant formula medicated serum on hydrogen peroxide (H 2O 2)-induced epithelial-mesenchymal transition (EMT) of human retinal pigment epithelial (ARPE-19) cells and its mechanism. Methods:Thirty female SPF grade SD rats aged 2 months old were selected.The rats were randomized into blank control group and Zhujing pill variant formula group according to random number table method, with 15 in each group, which were intragastrically administered with normal saline and ZhuJing pill variant formula solution for 7 days accordingly to prepare blank control serum and medicated serum.ZhuJing pill variant formula medicated serum was prepared with SD rats.ARPE-19 cells were divided into normal control group, model control group, blank serum group as well as 2.5%, 5.0% and 10.0% medicated serum groups, SB216763 group and SB216763+ medicated serum group.Normal and blank control groups were cultured in normal culture medium, while the other six groups were cultured in blank rat serum medium, medicated serum medium of corresponding concentration, 10 μmol/L SB216763 medium and 10 μmol/L SB216763+ 10.0% medicated serum medium, respectively.Normal control group was routinely cultured, while the other groups were routinely cultured for 24 hours, and then added with H 2O 2 with the final concentration of 200 μmol/L for 24 hours.Cell viability was assessed by cell counting kit-8 (CCK-8) assay, and cell migration ability was detected by Transwell assay.Intracellular reactive oxygen species (ROS) level was detected by dichloro-dihydro-fluorescein diacetate (DCFH-DA) assay, and MDA level was identified by sulfhydryl barbituric acid assay.The expression levels of Nrf2 pathway related proteins including nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), quinone oxidoreductase 1 (NQO-1) and EMT-related proteins including transforming growth factor-β2 (TGF-β2), protein kinase B (AKT), glycogen synthase kinase-3β (GSK-3β), snail family zinc finger 1 (SNAIL1), α-smooth muscle actin (α-SMA), epithelial cadherin (E-cadherin) in cells were measured by western blot assay.The use and care of animals complied with Regulations for the Administration of Affairs Concerning Experimental Animals. Results:There was no significant difference in cell survival rate among blank serum group, 2.5%, 5.0% and 10.0% medicated serum groups ( F=0.163, P>0.05). The cell survival rates were (100.50±5.91)%, (60.87±4.30)%, (73.27±4.46)%, (80.73±5.67)% and (89.90±4.97)% in normal control group, model control group, 2.5%, 5.0% and 10.0% medicated serum groups, and the number of migrating cells was (84.67±8.33), (222.33±13.58), (215.67±10.02), (174.67±10.60), (143.67±8.02) and (107.67±6.66) pcs/visual field in normal control group, model control group, blank serum group, 2.5%, 5.0% and 10.0% medicated serum groups, respectively, with significant differences among the groups ( F=26.628, 99.289; both at P<0.01). The contents of ROS and MDA in model control group were significantly increased in comparison with normal control group (both at P<0.01). The contents of ROS and MDA of 2.5%, 5.0% and 10.0% medicated serum groups were significantly decreased in comparison with model control group (all at P<0.01). The relative expression levels of SNAIL1, α-SMA, TGF-β2, p-AKT and p-GSK-3β proteins were significantly higher and the relative expression level of E-cadherin protein was significantly lower in model control group compared with normal control group, 2.5%, 5.0% and 10.0% medicated serum groups (all at P<0.05). Compared with normal control group, the relative expression level of cytoplasmic Nrf2 in model control group was decreased, while the relative expression levels of nuclear Nrf2, HO-1 and NQO-1 were increased, and the differences were statistically significant (all at P<0.05). Compared with model control group, the relative expression levels of cytoplasmic Nrf2 in 2.5%, 5.0% and 10.0% medicated serum groups were reduced, and the relative expression levels of nuclear Nrf2, HO-1 and NQO-1 were enhanced, and the differences were statistically significant (all at P<0.01). Compared with model control group, the relative expression level of cytoplasmic Nrf2 in SB216763 group was decreased, and the relative expression level of nuclear Nrf2 was increased, and the differences were statistically significant (both at P<0.05). Compared with SB216763 group, the relative expression levels of cytoplasmic Nrf2, SNAIL1 and α-SMA in SB216763+ medicated serum group were decreased, and the relative expression levels of nuclear Nrf2 and E-cadherin protein were increased, and the differences were statistically significant (both at P<0.05). Conclusions:ZhuJing pill variant formula medicated serum can inhibit H 2O 2-induced EMT in ARPE-19 cells.The mechanism may be related to the inhibition of AKT/GSK-3β pathway and the activation of Nrf2 signaling pathway.
