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.
【Abstract】Objective To investigate the prevention and treatment for recurrence of hepatitis B after liver transplantation on HBV-related diseases. Methods Making a literature summarization based on published papers review.Results Acute and chronic HBV-related diseases are the main indications of liver transplantation.Recurrence rate of hepatitis B is from 80% to 100% in the untreated patients after liver transplantation,and it affects the survivals of patients seriously.It has become a focus to prevent and treat the recurrence of hepatitis B.After a series of explotation and application,there have been a lot of drugs of preventing and treating HBV reinfection, including hepatitis B immunoglobulin,interferon and nucleotide analog antivirus drugs(lamivudine, famcyclovir, adefovir),etc.The therapeutic characteristics of them are different. Their utilizations of dividing or alliance are developing rapidly.Conclusion Liver transplatation is an effective therapy for HBV-related disease. Anti-HBV treatments perioperation play an important role in the improvement of succeed of liver transplantation.
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.
The interal changes of immunoglobulins in serum and bile among the rabbit models in partial biliary obstruction group (BO),partial biliary obstruction with infection group(BOI)and normal controls(Con)were studied. Concentrations of serum immunoglobulin A(IgA)in BO and BOI groups increase remarkably in all phases(Plt;0.001),Concentrations of serum IgG in both groups increase with the formation of gallstones. The IgG and IgA contents of bile samples in BO and BOI groups with negetive bacterial culture were much higher than that of the control group(Plt;0.05),but the Ig contents of bile with postive culture slightly lower than that of the control group.This experiment suggest in the formation of gallstones,the immunoglobulins of serum and bile had changed significantly.The Ig contents of bile have a relationship with the bacterial infection. Immunoglobulin A takes an important role in gallstone formation.
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 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.
Objective To summarize the research progress of CD90 protein. Methods The demestic and international published literatures related to CD90 protein in recent years were collected and reviewed. Results CD90 protein was involved in the cell-cell and cell-cytoplasm function. CD90 protein could promote axons growth and neural regeneration， and could induce apoptosis of thymus gland cells and stromal cells. 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.
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.
ObjectiveTo explore the effects of intraoperative lymphatic chemotherapy (LC) on immune functions of patients after esophageal carcinoma resection. MethodsPatients who underwent intraoperative LC during esophageal carcinoma resection in the Department of Thoracic Surgery of West China Hospital from March to October,2013 were prospectively included in this study, and patients who underwent esophageal carcinoma resection without intraoperative LC during the same period were also included as the control group. All the patients were divided into a pacitaxel LC group,a fluorouracil LC group,and a control group without LC. A total of 37 patients were included in this study including 25 male and 12 female patients with their age of 42-76 (61.89±7.95) years. There were 15 patients in the pacitaxel LC group,15 patients in the fluorouracil LC group,and 7 patients in the control group. Representative indexes of humoral immunity and cellular immunity in peripheral blood of all the patients were examined preoperatively and on the third and seventh postoperative day, and then compared among the 3 groups. ResultsAll the immune indexes of the 3 groups decreased after surgery to different extent. There was no statistical difference in preoperative and postoperative difference of immunoglobulin concentration between LC groups and the control group (P>0.05). CD8+ T cell count recovered more rapidly after surgery in LC groups than the control group. CD3+ T cells recovered most rapidly after surgery in the fluorouracil LC group. ConclusionLC is beneficial for the recovery of cytotoxic effects of T lymphocytes but may not promote humoral immunity for patients after esophageal carcinoma resection.
