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.
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.
Objective To observe the turbulence of regional intra-artery implantation chemotherapy and peripheral venous chemotherapy on immunologic function of patients. Methods Two weeks after radical operation of gastric carcinoma, chemotherapy was performed. Eighty-three patients were divided into two groups, one (42 patients) received peripheral venous chemotherapy (PVC) and the other (41 patients) received regional intra-artery implantation pump chemotherapy (RAIPC). The serum T-lymphocyte subsets and immunoglobulin level before and 1-4 days after the chemotherapy were measured. Results After PVC, proportion of CD3 and CD4, CD4/CD8 and IgG, IgA, IgM concentration in PVC group were significantly decreased compared with those before PVC （P＜0.05， P＜0.01）, and it is the same when compared with postRAIPC patients except for CD4 and IgM （P＜0.05）. In RAIPC group, there were no significant changes in proportion of CD3, CD4 and CD8, CD4/CD8 and IgG, IgA concentration between pre- and post-RAIPC patients. Conclusion After radical operation of gastric carcinoma, RAIPC affects the immunologic function more moderate than PVC.
ObjectTo systematically review the efficacy and safety of intravenous immunoglobulin (IVIG) for children with severe hand, foot and mouth disease in China. MethodDatabases including CNKI, CBM, WanFang Data, PubMed and The Cochrane Library (Issue 2, 2015) were searched to collect randomized controlled trials (RCTs) about IVIG combined with conventional therapy versus conventional therapy alone for severe hand, foot and mouth disease from inception to March 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 and Stata 9.0 software. ResultA total of 23 RCTs involving 2271 patients were included. The results of meta-analysis showed that, compared with the conventional therapy group, the IVIG group had higher total effective rate (RR=1.18, 95%CI 1.11 to 1.26, P<0.00001), shorter fever relieving time (MD=-1.47, 95%CI -1.80 to -1.15, P<0.00001), shorter rash regression time (MD=-1.61, 95%CI -2.51 to -0.71, P=0.0005), shorter remission time of nervous symptoms (MD=-2.14, 95%CI -3.02 to -1.25, P<0.00001), shorter mouth ulcer regression time (MD=-1.36, 95%CI -2.27 to -0.4, P=0.004), and shorter average length of hospital stay (MD=-2.46, 95%CI-3.29 to -1.63, P<0.00001). ConclusionCompared with conventional therapy alone, IVIG combined with conventional therapy can improve the effect for severe hand, foot and mouth disease. Due to the limited quality of the include studies, more high quality studies are needed to verify the above conclusion.

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.
ObjectiveTo compare the clinical recovery and immune response between laparoscopic-assisted and open D2 gastrectomy for advanced gastric cancer. MethodsThe clinical data of 53 patients with advanced gastric cancer from January 2012 to October 2013 were studied prospectively. According to random number table, patients were randomly divided into laparoscopic-assisted group(LA group, n=27) and open operation group(OO group, n=26). Operative time, blood loss, time to passage of flatus, time to resume soft diet, after bed time, postoperative hospital stay, and number of retrieved lymph nodes were compared respectively between the two groups. The changes in CD3, CD4+, CD8+, IgG, IgA, IgM, and CRP were examined respectively by using flow cytometry and immunoturbidimetric assays on the preoperative day 1, and on the postoperative day 1 and 7. ResultsThe operative time was longer significantly in LA group than that in OO group(P < 0.05). The mean blood loss, the first flatus time, after bed time, and postoperative hospital stay in the two groups were all different statistically(P < 0.05), and all were better in LA group. However, the mean number of retrieved lymph nodes and the time to resume soft diet were not significantly different in the two groups(P > 0.05). On the day 1 and 7 after operation, the CD3, CD4+, and CD8+ significantly decreased as compared with those preoperatively in two groups(P < 0.01, P < 0.05). On the day 1 after operation, the levels of IgG, IgA, and IgM significantly decreased as compared with those preoperatively in two groups(P < 0.05). Those immunoglobulin in LA group recovered to close to the level before surgery, but in OO group sustained lower level(P < 0.05). On the day 1 and 7 after operation, CRP level significantly increased as compared with those preoperatively in two groups(P < 0.01, P < 0.05). Those changes of above index were not significantly different between the LA group and OO group on the day 1 after operation(P > 0.05). All index recovered gradually in the two groups on the day 7 after operation and were better in LA group(P < 0.05, except IgA). ConclusionLaparoscopic radical gastrectomy for advanced gastric cancer resulted in a quicker clinical recovery and a lesser depression to the perioperative cellular and humoral immune function.
Immunoglobulin G4-related disease (IgG4-RD) is a new disease entity recognized at the start of this century noted to be involving many organ systems including endocrine system and thyroid in particular. It represents an immune mediated fibro inflammatory condition with characteristic histopathological appearance affecting single or multiple organs. In general, immunoglobulin G4-related thyroid disease (IgG4-RTD) is rarely considered and it may be isolated or with other organ involvement. Four subcategories of IgG4-RTD have been identified so far: Riedel thyroiditis, fibrosing variant of Hashimoto thyroiditis, immunoglobulin G4-related Hashimoto thyroiditis, and Graves disease with elevated immunoglobulin G4 levels. The diagnostic approach is complex and the work up relies on the coexistence of clinical features, histological features and serological evidence. Demonstration of the classic histopathological features is vital to diagnose IgG4-RD in most cases, and biopsy proof is preferred strongly by most disease experts before the initiation of treatment. The treatments for IgG4-RTD include medical and surgical options. Steroids are first line treatment though it may need further evaluation. Tamoxifen and rituximab are second line treatment for steroid resistant patients. Surgical excision of thyroid gland in presence of compression symptoms is the surgical option. Inspite of pathophysiology of the disease being poorly understood till now, early and prompt diagnosis and an early treatment initiation can improve the outcomes.
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.
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.
