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.
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.
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.
Immunogammopathy maculopathy is a newly discovered retinopathy associated with macroglobulinemia in recent years. The main manifestations were retinal vein convulsion and dilation caused by high blood viscosity, retinal interlaminar effusion and macular serous detachment. With the prolongation of the course of disease, the photoreceptor layer and RPE layer in the detachment area showed atrophic changes. The pathogenesis of ophthalmopathy is still unknown. Understanding the clinical features, diagnosis, differential diagnosis and treatment of ophthalmopathy is of great significance for understanding this kind of disease and improving the level of diagnosis and treatment of ophthalmopathy.
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.
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.
ObjectiveTo investigate the influence of immunoglobulin (Ig)on celluar immune function of postoperative infants with cyanotic congenital heart disease (CCHD). MethodsForty infants who underwent surgical repair of CCHD in Department of Cardiac Surgery, Children's Hospital of Hebei Province from March to December 2012 were enrolled in this study. All the patients were randomly divided into 2 groups. Patients in Ig group received intravenous Ig treatment at the dosage of 1g/ (kg·day)for 2 days postoperatively in addition to routine therapy. Patients in the control group only received routine therapy without Ig treatment. Five ml venous blood samples of all the patients were taken preoperatively, 0.5 hour and 2 days postoperatively to examine serum levels of interferon gamma (IFN-γ)and interleukin-4 (IL-4)with double-antibody sandwich enzyme-linked immunosorbent assay (ELISA), which were compared between the 2 groups. ResultsThere was no statistical difference in serum levels of IL-4 or IFN-γ preoperatively and at 0.5 hour postoperatively between the 2 groups (P > 0.05). Serum levels of IL-4 and IFN-γ at 0.5 hour postoperatively were significantly higher than preoperative levels in the 2 groups respectively (P=0.000). Serum IL-4 level of Ig group 2 days postoperatively was not statistically different from preoperative level (P=0.362), while serum IL-4 level of the control group 2 days postoperatively was significantly higher than preoperative level (P=0.006). Two days after the operation, serum levels of IL-4 and IFN-γ of Ig group were significantly lower than those of the control group respectively (P=0.039 and 0.007 respectively). Compared with serum levels at 0.5 hour postoperatively in the control group, serum IL-4 level at 2 days postoperatively decreased by 20.08% (P=0.001), and serum IFN-γ increased by 17.80% (P=0.001). Compared with serum levels at 0.5 hour postoperatively in Ig group, serum IL-4 level at 2 days postoperatively decreased by 35.38% (P=0.000), and serum IFN-γ only increased by 7.60% (P=0.143). ConclusionCellular immune function disorder caused by the operation and cardiopulmonary bypass can be effectively improved by postoperative intravenous Ig administration, which may help to reduce postoperative complications.
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.
