IgG4-related disease (IgG4-RD) is a chronic, immune-mediated inflammatory and fibrotic condition that can affect virtually any organ system. While some patients experience involvement of only a single organ, isolated IgG4-RD of the mediastinum is even rarer. This article reports a case of a 48-year-old male patient with isolated IgG4-RD of the middle mediastinum. After a biopsy failed to establish a definitive diagnosis, the patient underwent a right thoracotomy-assisted mediastinal tumor resection via video-assisted thoracoscopic surgery. The tumor was completely resected during the procedure, which lasted 130 minutes, with an estimated blood loss of approximately 50 mL. The patient had a favorable postoperative course and satisfactory clinical outcome. No glucocorticoid or other medical treatment was administered postoperatively, and there was no recurrence during a 6-month follow-up period.
ObjectiveTo systematically review the efficacy of immunoglobulin for treatment of clinical diagnosed viral encephalitis in China.MethodsCNKI, VIP, WanFang Data, PubMed, ScienceDirect, The Cochrane Library and EMbase databases were electronically searched to collect randomized controlled trials (RCTs) of immunoglobulin for treatment of clinical diagnosed viral encephalitis in China from inception to January 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed by using RevMan 5.4 software.ResultsA total of 57 RCTs involving 4 431 patients were included. The results of meta-analysis showed that in both children and adults of clinically diagnosed viral encephalitis, the combination of immunoglobulin could reduce the mean recovery time of fever, unconsciousness, convulsion, emesis, average hospitalization time, and non-effective rate. Moreover, there was no difference in the incidence of adverse effects between the two groups.ConclusionsCurrent evidence shows that immunoglobulin is superior to conventional therapies both in adults and children patients of clinically diagnosed viral encephalitis. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.
Objective To observe the change of serum associated factors concentrations in the patients with idiopathic choroidal neovascularization (CNV).Methods The clinical data of 21 patients (21 eyes) with idiopathic CNV (CNV group) and 20 normal individuals (control group) were retrospective analyzed. Serous concentrations of vascular endothelial growth factor (VEGF), tumor necrosis factor alpha;(TNFalpha;), interleukin 1-beta; (IL1-beta;), IgG, IgA, IgM, IgE, CH50, C3, C4 and Creactive protein (CRP) were assayed by enzymelinked immunosorbent assay (ELISA) and immunonephelometry. Results The level of VEGF in CNV group was significantly higher than that in control group(t=2.340，P=0.025). The level of IgE in CNV group was significantly lower than that in control group(Z=-2.765，P=0.006). The other factors were not significantly different between the two groups（Pgt;0.05）.Conclusion VEGF and IgE may play an important role in the formation of idiopathic CNV.
ObjectiveTo learn the serum immunoglobulin G4 (IgG4) level in patients with pemphigus vulgaris (PV) in the active phase by detecting the IgG4 concentration in the patients with PV. MethodsWe collected the serum samples from patients with active-phase PV (including acute-onset and chronic active phases) between April and December 2014. The serum IgG4 level was detected by immuno-scatter turbidmetry, and the difference of serum IgG4 level between PV patients and normal subjects was assessed by Student's t-test. ResultsThirty-two patients with pemphigus vulgaris in the active phase were enrolled for this study, among whom 22 (including 8 males and 14 females) had normal serum IgG4 level, 8 (including 3 males and 5 females) higher and 2 (including 1 male and 1 female) lower. Compared with normal subjects, the average level of serum IgG4 in PV patients was not significantly different (P>0.05). The serum IgG4 level of acute-onset and chronic active PV patients was (1.015±0.825) g/L and (1.058±1.133) g/L, respectively, with no significant difference (P>0.05). ConclusionThe serum IgG4 level of patients with pemphigus vulgaris in the active phase can be normal, higher or lower. And there is no obvious difference in the serum IgG4 level between acute-onset and chronic active PV patients.
Objectives To evaluate the effects of hepatitis B immunoglobulin (HBIG) intrauterine injection before delivery on interrupting mother-to-child transmission of hepatitis B virus (HBV). Methods The randomized controlled trials (RCTs) on HBIG intrauterine injection on interrupting mother-to-child transmission of HBV published between January 1992 and May 2012 were searched in The Cochrane Library, PubMed, CBM, CNKI, VIP, WanFang Data, etc. The studies were screened according to inclusive and exclusive criteria, the data were extracted, the quality was assessed by two reviewers independently, and meta-analysis, publication bias and sensitivity analysis was conducted using Stata software. Results The total 42 studies involving 7 212 infants were included. The randomized methods were asserted in all studies, three of which reported the details of randomization, one study mentioned blinded method, two studies mentioned incomplete outcome data, 13 studies had other potential threats to validity, no allocation concealment and selective outcome reporting was mentioned. Results of meta-analysis indicated that the infant HBV infection rates in the HBIG group and the control group were 8.971% and 25.470% (RR=0.359, 95%CI 0.303 to 0.425) at birth, 5.385% and 13.919% (RR=0.391, 95%CI 0.278 to 0.550) after half a year, 5.318% and 12.457% (RR=0.429, 95%CI 0.335 to 0.551) after one year; the infant anti-HBs rates in the HBIG group and the control group were 61.964% and 14.523% (RR=6.712, 95%CI 1.920 to 23.467) at birth, 77.754% and 66.311% (RR=1.209, 95%CI 0.989 to 1.478) after half a year. Funnel graphs showed that there was publication bias. Sensitivity analysis showed that the results except the infant anti-HBs protection after half-a-year follow-up were stable and consistent with the original results. Conclusion Injection of HBIG during pregnancy for HBV-carrying mothers can effectively reduce the occurrence of HBV whenever at birth, after half a year or after one year, and increase the infant anti-HBs protection rate at birth, but it is ineffective to improve anti-HBV protection rate after half a year. Owing to the low quality of the included studies and existence of biases, this conclusion should be cautiously put into clinical practice.

CD90 protein participated in cell adhesion， extravasation and transfer， and the regulation of fibrosis. CD90 protein was a potential marker for cancer stem cells. Conclusion CD90 protein is very important in development of many diseases， and can provide a new molecular target to diagnose and treat neoplasms.
Immunoglobulin A nephropathy (IgAN) is an immune-mediated chronic inflammatory disease with a complex pathogenesis and diverse clinical manifestations. Currently, there is no specific treatment plan. Programmed cell death is an active and orderly way of cell death controlled by genes in the body, which maintains the homeostasis of the body and the development of organs and tissues by participating in various molecular signaling pathways. In recent years, programmed cell death has played an important regulatory role in the occurrence and development of IgAN, involving complex signaling pathways. Under pathological conditions, it may relieve kidney damage through various pathways such as reducing oxidative stress, inhibiting inflammation, and improving energy metabolism. This article provides a review of the research progress of IgAN in apoptosis, autophagy, pyroptosis, ferroptosis,and cuproptosis in order to provide new therapeutic targets for IgAN.
The change of Ig-forming cells in the gallbladder mucoderm were studied in the rabbit models.One hundred rabbits were randomly divided into the control group(Con,n=10),simple biliary obstruction group(BO,n=45)and biliary obstruction and infection group(BOI,n=45).The results showed that only a few Ig-forming cells presented in the gallbladder mucoderm of normal rabbit.At the 3rd,7th and 14th day,the quantities of IgG and IgA-forming cells in the mucoderm in BO group remained unchange,but increased much higher in BOI group(Plt;0.001),especially in IgG formation.This study suggests that the gallbladder of rabbit may be the important place of Ig-formation.The quantities of Ig-forming cells in bilitary tract may have a close relationship with the gallstone formation.
Objective To assess the effects of combining intravenous immunoglobulin for systemic lupus erythematosus (SLE) by analyzing the randomized controlled trials (RCT). Methods The electronic databases such as PubMed (1966 to Aug. 2010), EMbase (1974 to Aug. 2010), The Cochrane Library (Issue 2, 2010), CNKI (1994 to Aug. 2010), VIP (1989 to Aug. 2010), CBM (1978 to Aug. 2010) and Chinese Medical Association Digital Periodicals (1998 to Aug. 2010) were searched to collect RCTs of intravenous immunoglobulin for the patients with SLE. The methodology quality of the included studies was evaluated in accordance with RCTs quality evaluation standard of the Cochrane Handbook 4.2.6, and meta-analyses were performed by using RevMan 5.0 software. Results Four RCTs involving 154 participants were included. The results of meta-analyses showed that compared with cyclophosphamide pulse therapy, the combining intravenous immunoglobulin markedly reduced the SLE disease activity index (MD= –3.09, 95%CI –4.21 to –1.97), the incidence of infection (OR=0.24, 95%CI 0.11 to 0.54), the proteinuria (MD= –1.09, 95%CI –2.11 to –0.06), and the relapse of SLE (OR=0.07, 95%CI 0.01 to 0.37). But there was no significant difference in elevating of complement between two groups. Conclusion According to the results of meta-analyses, compared with cyclophosphamide pulse therapy, cyclophosphamide combining intravenous immunoglobulin may be more efficient in improving clinical symptoms, decreasing incidence rate of infectious diseases, and reducing relapse for SLE patients.
