Objective:To investigate the current status of research in gene therapy for retinitis pigmentosa (RP) from 2005 to 2024.Methods:The literature related to gene therapy for RP included in the Web of Science Core Collection dataset from January 1, 2005 to September 15, 2024 was retrieved and screened. The bibliometrix package of R software was used to analyze the annual trend of the number of publications, citation frequency, distribution of countries/regions of the literature, and distribution of journals containing the articles. CiteSpace software was used to perform keyword clustering analysis and the keywords bursts analysis.Results:A total of 209 articles were included. There was an overall fluctuating upward trend of annual publications from 2005 to 2024, with the highest number of publications in 2023 at 26 (12.4%, 26/209), and the lowest number of publications in 2006 at 2 (0.9%, 2/209). There was an overall increasing trend in the frequency of citations to relevant literature. Corresponding authors from the United States had the highest total number of publications with 98 (46.9%, 98/209). Among authors, Hauswirth from the University of Florida, USA, had the most with 25 (12.0%, 25/209). Among institutions, Columbia University, USA, had the most with 55 (26.3%, 55/209). Among journals, Mol Ther had the most with 25 (12.0%, 25/209), and it had the highest 2023 impact factor of 12.1. Keyword clustering analysis yielded eight valid clusters, namely #0 P23H, #1 AAV, #2 PDE6B,#3 CRB1, #4 RPGR, #5 antisense oligonucleotide, #6 NR2E3, and #7 NRL, which intersected with each other with good continuity. The keywords bursts analysis showed that the keyword with the longest emergence time was RNAi, followed by PDE and PDE6. USH2A, CRB1, CRISPR Cas9, base editing, and ORF15 were keywords that emerged in recent years and were continuously studied. Conclusions:RP gene therapy research literature has shown an increasing trend from 2005 to 2024, with the highest number of publications from research organizations and scholars in the United States. Currently, studies focus on RHO, PDE6B, CRB1, RPGR, NR2E3, and NRL gene. In recent years, there has been a gradual increase in studies on USH2A, CRB1 genes, and the RPGR ORF15 region. CRISPR Cas9 and base editing gene therapy strategies are being developed.

Anxiety disorder is a major symptom of autism spectrum disorder (ASD) with a comorbidity rate of ~40%. However, the neural mechanisms of the emergence of anxiety in ASD remain unclear. In our study, we found that hyperactivity of basolateral amygdala (BLA) pyramidal neurons (PNs) in Shank3 InsG3680 knock-in (InsG3680^+/+) mice is involved in the development of anxiety. Electrophysiological results also showed increased excitatory input and decreased inhibitory input in BLA PNs. Chemogenetic inhibition of the excitability of PNs in the BLA rescued the anxiety phenotype of InsG3680^+/+ mice. Further study found that the diminished control of the BLA by medial prefrontal cortex (mPFC) and optogenetic activation of the mPFC-BLA pathway also had a rescue effect, which increased the feedforward inhibition of the BLA. Taken together, our results suggest that hyperactivity of the BLA and alteration of the mPFC-BLA circuitry are involved in anxiety in InsG3680^+/+ mice.

Objective:To observe the clinical efficacy of Chinese materia medica soaking therapy combined with cervical rotation-traction manipulation in the treatment of cervical spondylotic radiculopathy (CSR).Methods:A randomized controlled trial was conducted. Totally 84 CSR patients from the Orthopedics Department of Shunyi Hospital, Beijing Traditional Chinese Medicine Hospital from April 2023 to May 2024 were selected as the observation subjects. They were divided into two groups using a random number table method, with 42 patients in each group. The treatment for both groups lasted for 14 d. VAS scale was used to assess pain levels before and after treatment, OASTCSR was used to evaluate cervical function, and NDI was used to assess cervical functional status; adverse reactions during treatment were observed and recorded, and clinical efficacy was evaluated.Results:The total effective rate was 95.24% (40/42) in the treatment group and 80.95% (34/42) in the control group, with statistical significance ( χ2=4.36, P=0.029). After treatment, the VAS score (1.60±1.21 vs. 2.91±1.12, t=-1.89), the OASTCSR score (5.17±2.14 vs. 9.31±3.82, t=-11.57), and the NDI score (9.17±2.13 vs. 13.36±3.45, t=-10.82) in the treatment group were lower than those in the control group ( P<0.001 or P<0.05). During the treatment period, neither group experienced any adverse reactions. Conclusion:The combination of Chinese materia medica soaking therapy and cervical rotation-traction manipulation can significantly improve the clinical symptoms and quality of life of patients with CSR, and its efficacy is superior to the use of cervical rotation-traction manipulation alone.

Objective:To evaluate the clinical value of CD4 + T lymphocyte subsets such as helper Th2 in patients with recurrent uveitis (BU) in Beh?et′s disease (BD). Methods:The clinical data of 153 hospitalized patients diagnosed with Beh?et′s disease from January 1, 2020 to June 30, 2023 in the Second Hospital of Shanxi Medical University were retrospectively analyzed. The subsets of CD4 + T lymphocytes were measured, including helper T cells (Th cells) such as Th1, Th2, Th17 and regulatory T cells (Treg cells), biochemical lipid indexes (TC, TG, etc.), the frequency of oral ulcers in the past 1 year, the frequency of genital ulcers in the past 1 year, and drug use before admission;According to whether there was ocular involvement and uveitis, 153 cases of BD were divided into Beh?et non-uveitis group (non-BU group) and Beh?et uveitis group (BU group). The above indexes and independent correlation factors of recurrent BU were compared between BU group and non-BU group;The above indexes and independent correlation factors of recurrent BU were compared between BU group and non-BU group. The levels of cytokines and ICBD total score, the correlation between ICBD total score and various cytokines, and the diagnostic performance of Th2 cells were compared between BU group and non-BU group.The statistical methods were Mann-Whitney U test, independent sample t test, Chi-square test, multiple logistic regression analysis, Pearson correlation analysis and receiver operating characteristic curve (ROC) analysis. Results:①The levels of Th1, Th2, Th17 cells, TC and TG in BU group were higher than those in non-BU group [133.87 (93.38, 229.87)/μl vs. 102.51(64.25, 149.23)/μl] and [9.43 (5.84, 14.13)/μl vs. 6.78(4.23, 9.44)/μl], [15.53 (9.36, 25.27)/μl vs. 9.83(5.46, 14.76)/μl], [4.21 (3.89, 4.90) mmol/L vs. 3.89(3.37, 4.34)mmol/L)], [1.43(1.00, 2.21)mmol/L vs. 0.96(0.69, 1.38)mmol/L], The differences were statistically significant ( Z=-3.24, Z=-3.05, Z=-3.94, Z=-2.25, Z=-3.47; all P<0.05); There was no statistical significance in Chi-square test between the two groups ( χ2=5.69, P>0.05).②The levels of IL-2, IL-10 and total ICBD score in BU group were higher than those in non-BU group, with statistical significance ( Z=-2.12, Z=-2.29, t=-6.48; all P<0.05). ③ The results of multiple logistic regression analysis showed that Th2 was an independent correlation factor for BU [ OR value (95% CI) was 1.143(1.007, 1.298), P=0.039]. The total score of BU patients was correlated with Th2 and Th17 cells. ROC analysis showed that the sensitivity of Th2 in diagnosing BU was 68.8%, the specificity was 49.5% and the area under the curve (95% CI) was 0.697 (0.585, 0.809) (P=0.001). Conclusion:CD4 + T lymphocyte subsets such as the absolute number of Th2 cells are related to BU, which is an important indicator to observe the severity of disease progression in BU patients, and has certain clinical value in evaluating the recurrence of BU in BD patients.

Myositis antibodies are divided into myositis-specific autoantibodies(MSA)and myositis-associated autoantibodies(MAA).There are heterogeneity in the mechanism,clinical features and prognosis of interstitial lung disease(ILD)in the different myositis antibodies.In MSA,anti-melanoma differentiation-related gene 5(MDA5)antibody and anti-aminoacyl synthetase(ARS)antibody are highly correlated with the occurrence of ILD.Patients with MDA5+DM-ILD usually have a rapidly progressive and poor prognosis.The progress of ILD in ARS+DM patients was slow,and the response to treatment is good,but it is easy to relapse.In MAA,anti-Ro52 antibodies often coexist with MSA antibodies,and clinical manifestation is closely related to coexisting antibodies.This review has summarized roles of myositis antibodies in ILD.

Objective To explore characteristics of co-infection of Chlamydia pneumoniae(Cpn)and severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),and identify their effect on SARS-CoV-2-induced inflammatory response.Methods Patients with coronavirus disease 2019(COVID-19)who received treatment in a hospital in Chenzhou City from December 20,2022 to February 20,2023 were selected.According to the severity of COVID-19,severe and critical cases were classified as the severe symptom group,while mild and moderate cases were classified as the mild symptom group.Meanwhile,according to the age of patients(≥18 years old as adults,＜18 years old as juveniles),they were divided into the adult severe symptom group,adult mild symptom group,juvenile severe symptom group,and juvenile mild symptom group.Propensity score was adopted to match age,gender,and under-lying diseases of patients in severe symptom and mild symptom group in a 1∶1 ratio.Bronchoalveolar lavage fluid(BALF),throat swabs,and serum specimens of patients were collected.Cpn IgG/IgM antibody was detected by enzyme-linked immunosorbent assay(ELISA),levels of 12 common cytokines(including interleukin-8[IL-8])in BALF were detected by flow cytometry,differences among groups were compared.Results A total of 102 patients were included,with 61 severe and critical(severe symptom)patients,as well as 41 mild and moderate(mild symp-tom)patients.There were 71 patients aged ≥18 years and 31 juvenile patients aged＜18 years.There were 39 pa-tients in the adult severe symptom group and 32 in the adult mild symptom group,and 30 pairs were successfully matched through propensity score analysis.There were 22 patients in the juvenile severe symptom group and 9 in the juvenile mild symptom group,and 8 pairs were successfully matched through propensity score analysis.Among COVID-19 patients,the positive rates of Cpn IgG and IgM were 36.27％(n=37)and 8.82％(n=9),respective-ly,with 1 case positive for both Cpn IgG and IgM.The level of interferon(IFN)-α in serum specimens from adult patients with severe symptom combined with positive Cpn IgG was higher than that of IgG negative patients(P=0.037).There was no statistically significant difference in the levels of other cytokines in BALF and serum speci-mens between the two groups of patients(all P＞0.05).The levels of IL-8 and IL-17 in serum specimens of patients with positive Cpn IgG in the adult mild symptom group were both higher than those in Cpn IgG negative patients(both P＜0.05).The levels of IL-8 in both BALF and serum specimens from Cpn IgM positivity patients in the ju-venile mild symptom group were higher than those from patients with negative Cpn IgM(both P＜0.05).Logistic regression analysis results showed that Cpn IgG and IgM positivity were not risk factors for the development of se-vere COVID-19.Conclusion Combined Cpn infection is not a risk factor for the development of severe symptom in COVID-19 patients,and Cpn infection has limited impact on the secretion of inflammatory factors caused by SARS-CoV-2.

The emerging and re-emerging arthropod-borne infectious diseases pose a serious threat to global public health security. Field and laboratory studies of arthropods of medical importance are essential and critical for the prevention and control of arthropod-borne infectious diseases. Various institutions or universities in China have been conducting research in the field or laboratory study of arthropods of medical importance, but up to 2023, it is still lacking detailed biosafety guidelines or recommendations that can guide the related work for arthropods of medical importance. In order to proactively address potential biosafety issues in the field or laboratory activities related to arthropods of medical importance, improve the standardization of arthropod biosafety classification, operations, and protection, and ensure the safety of practitioners, an expert consensus on the biosafety recommendation of arthropods of medical importance in field and laboratory has been developed, aiming to guide the future work of arthropods and ensure the national biosafety and biosecurity of China.
