Objective To investigate the relationship between human leukocyte antigen(HLA)-B51 and Behcet′s disease (BD) with uveities. Methods HLA-A and HLA-B antigen of 27 pateints with BD and 30 healthy persons were detected by microly mphocyte toxicity asssay. HLA-B51 allele (HLA-B5101-B5107) in BD patients with positive HLA-B51 antigen and the controls was detected by polymerase chain reaction-sequence specific primer(PCR-SSP). Results The positive rate of HLA-B51 was 63% and 16.7% in BD patients and the controls, respectively (χ2=12.9, P＜0.001, Pc＜0.05,RR=8.5). Uveities was found in 11 out of 27 BD patients with uveitis. No relativity was found between HLA-B51 and uveitis in BD patients(RR=2.07,χ2=0.759,P＞0.25),and weak association was found between HLA=B5101 and uveitis (RR=2.67, χ2=1.395, P＞0.10). Conclusions HLA-B51 might be a susceptible gene for BD, and there was a weak association between HLA-B51(HLA-B5101) and BD patients with uveitis.(Chin J Ocul Fundus Dis，2004，20：203-205)
Eighteen male patients and 10 female patients with Bt.Behccedil;et's disease were addressed to study the influences of sex factor on Behccedil;et's disease. It was found that recurrences of uveitis were more frequent in malepatients than in females,and that male patients were worse than females in prognosis due to the high severity of retinal vasculitis and the low sensitivity to treatment.It is pressumed that the sex hormone may, at least in part,contribute to the
diffrenees between the male and female patients. （Chin J Ocul Fundus Dis,1994,10:143-145）
Behccedil;et's disease,a stubborn malady,has extremely bad visual prognosis due to the recurrence of uveitis. The combination of chlorambucil with traditional Chinese medicine herbs was designed to treat 16 patients with Behccedil;ets disease,resulting in total remission of uveitis in 11 patients and partial remission in 5 patients. Visual improvement was seen in 63.33% of the eye involved in Bebcet's disease. The extraoeular manifestations such as oral aphthae,multiform skin lesions,genital ulcer and muscular pain were disappeared in 10 patients and dramatically improved in 6 patients. The treatment was well tolerated by the patients with few side effects. The indications,side etfeets and relevant problems of the treatment were discussed based on the results presented here. （Chin J Ocul Fundus Dis,1994,10:142-148）
Objective
To evaluate the therapeutic effects of vitrectomy on chronic and refractory Behcet′s diseases.
Methods
The clinical data of 8 patients (10 eyes) with Behcet′s diseases from 0.5 to 3 years after vitrectomy were retrospectively analyzed. Pre-and post-operative visual acuity, control of inflammation after the surgery, and the recurrence were observed and analyzed. Both of the eyes were involved in all of the patients, including complete Behcet′s diseases in 5 and incomplete in 3.
Results
Vitreous opacity and liquefaction were found in all of the involved eyes, dark retina and thin retinal vessels were seen in most of the eyes, and vascular obstruction or sheath-like changes in different degrees were detected in some eyes. Improvement of visual acuity was observed in all of the eyes which had undergone the treatment after the operation. There was significant difference between the visual acuity before the surgery and at the 1st and 2nd week and the 1st and 6th month after the surgery. During the follow-up period, recurrence of the inflammation was found in 3 eyes within 1 month and in 6 eyes within 6 months; no recurrence was found in 4 eyes after the operation. No acute recurrence of inflammation was found after operation in the involved eyes.
Conclusion
Vitrectomy for chronic and refractory Behcet′s diseases may improve the visual acuity of the involved eyes, and the surgery is safe and effective.

Behcet's Disease (BD) is a multisystem vasculitis characterized by disease alternated with recurrent episodes and remissions, involving genital, oral, ocular uvea, cutaneous, and articular manifestations. The nuclear factor (NF)-κB signaling pathway paly an important role in the BD progression. It encompasses diverse gene, protein, and cellular regulatory mechanisms operating across various levels, alongside microbiological and experimental studies involving animals and cells. At the protein research findings, activation of the NF-κB pathway in BD patients is marked by elevated plasma levels of soluble CD40 ligand, which stimulates neutrophils to release reactive oxygen species and extracellular traps, thereby promoting inflammation. At the cellular research findings, macrophages in BD patients polarize towards classically activated macrophages phenotype through the NF-κB pathway, exacerbating the inflammatory response. The activation of NF-κB is associated with increased expression of anti-apoptotic proteins in T cells, leading to prolonged inflammation. Microbiological investigations reveal that the decreased gut microbiota diversity in BD patients compromises intestinal barrier integrity. NF-κB pathway involvement in regulating neutrophil and type 1 helper T cell (Th) 1/Th17 cell function worsens inflammation. Genetically, BD patients exhibit polymorphisms in immune regulatory genes, which contribute to inflammation through the NF-κB pathway. Mutations in NF-κB-associated genes elevate the risk of BD, while mutations in the endogenous inhibitor A20 lead to abnormal NF-κB activity, sustaining inflammation. Animal experiments and in vitro experiments corroborate the efficacy of NF-κB inhibitors in attenuating inflammation. Targeting upstream inflammatory factors within the NF-κB pathway yields positive outcomes in BD patients. In summary, the NF-κB signaling pathway plays a pivotal role in the development of BD. Developing NF-κB inhibitors may open new avenues for treating BD. Further research is necessary to comprehensively elucidate the precise mechanisms by which NF-κB operates in the pathogenesis of BD, as well as its potential clinical applications in therapy.
ObjectiveTo identify the effects of transition to siblinghood (TTS) on the firstborn children’s emotions and behaviors, and to define the time of TTS.MethodsCBM, VIP, CNKI, WanFang Data, PubMed, Web of Science and EBSCO were electronically searched to collect studies on the emotional and behavioral characteristics of firstborn children in TTS from inception to December 31st, 2019. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies. Then, qualitative methods were used to analyze the studies.ResultsA total of 13 studies involving 980 children were included. 12 behavioral related studies explored self-behavior of the firstborn children during TTS, 3 studies focused on the interaction behavior between the firstborn children and their parents, the firstborn children and the second children. The systematic reviews found that TTS showed both positive and negative effects on the behavioral characteristics of firstborn children, primarily the negative effects. Firstborn children’s anxiety, confrontation and attachment showed 3 different patterns over time, respectively. Two studies showed the increase of negative emotions of firstborn children during TTS. The time range of TTS was mainly concentrated in the third trimester to 12 months after the birth of the second child.ConclusionsThe current evidence shows that TTS primarily increases the negative emotions and behaviors of firstborn children, and the behaviors of firstborn children changes over time. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective
To investigate the suicide related factors of the teenagers after trauma and further discuss the prevalence and related factors of suicide idea plan and behavior.
Methods
Using the general information questionnaire and the Youth Risk Behavior Survey (YRBS) to investigate the primary and secondary students in the nine worst-hit areas in Wenchuan earthquake of 2008, with cluster random sampling and the class as a sampling unit, to extract random 110 primary and middle schools and gather their general information, disaster-related cases and scores of suicide in YRBS. According to the different types of data, we used descriptive statistics,t test,Chi square test and Logistic regression analysis and respectively use single factor analysis and multivariate logistic regression analysis for suicide idea, plan and behavior.
Results
A total of 7 833 questionnaires were sent out and a total of 7 521 questionnaires were collected and the recovery rate was 96. 02%. Among them, there were 6 875 valid questionnaires (91.41%) and 636 invalid questionnaires. According to the investigation, the prevalence of the primary and secondary students which had seriously considered suicide was 6. 90%, which had a plan to commit suicide was 4.00% and which tried to take over the action of suicide was 2.70%. With general information for the independent variable, logistic regression analysis showed that whether there had seriously considered suicide as the dependent variable: age (OR=1.178, 95%CI 1.098 to 1.178) and changed in family structure after the earthquake (OR=1.360, 95%CI 1.360 to 1.085) were risk factors for post disaster the teenagers with suicide idea; whether there had been plan to commit suicide as the dependent variable: age (OR=1.099, 95%CI 1.050 to 1.150), the history of being buried in ruin (OR=2.155, 95%CI to 1.104 to 4.205) and changed in family structure after the earthquake (OR=1.495, 95%CI 1.128 to 1.981) were risk factors for post disaster the teenagers with suicide plan; whether took over the action of suicide as the dependent variable: male (OR=1.513, 95%CI 1.122 to 2.039) and changed in family structure after the earthquake (OR=1.555, 95%CI 1.112 to 2.175) were risk factors for post disaster the teenagers with suicide behavior.
Conclusion
Age and changed in family structure after the earthquake were the risk factors for suicide idea and age was positively correlated with suicidal idea. Age, had the history of being buried in ruin and changed in family structure after the earthquake were the risk factors for suicide plan and age was positively associated with suicide plan. Male and changed in family structure after the earthquake were the risk factors for suicide behavior. Among them, changed in family structure after the earthquake was the common risk factor. So there should be targeted psychological assessment and psychological rehabilitation intervention to avoid the risk of suicide among the teenagers after the disaster.
