Immunoglobulins ( Ig ) , also called antibodies, are important components in humoral -mediated immunity. Ig can bind with their receptors, called immunoglobulin receptors ( IgR ) , trigger biologic activities respectively. Different sub-types of Igs show different function. And IgRs have been treated as therapeutic targets in inflammation and immunity related dis-eases for many years. This article reviewed the recent progresses in the study of IgR function and its therapeutic role in inflamma-tion and immunity related diseases.

Objective To investigate the proportion of different types, distribution of genders, ages as well as the relative factors in inpatient with glaucoma. Design Retrospective case series. Participants 5058 cases of inpatients in Xingtai Eye Hospital, Hebei province from June 2004 to May 2009 were included. Methods Statistical analysis was conducted for 5058 cases of inpatients with glausoma. Main outcome Measures The type of glaucoma, age, gender and their percentages. Results In all 5058 cases, the patients with primary glaucoma, secondary glaucoma and congenital glaucoma accounted for 59.07%, 37.92% and 3.01% respectively. Primary angle-closure glaucoma (PACG) accounted for 88.65% in primary glaucoma, and primary open angle glaucoma (POAG) accounted for 11.35%. In PACG, acute PACG accounted for 53.15%, chronic PACG 46.85%;The female over forty accounted for 69.54%, male 26.95%. In POAG, the female over forty accounted for 69.54%, male 28.02%. From June 2004 to May 2005, POAG accounted for 11.32% in primary glaucoma, 12.44% from June 2008 to May 2009. There was no statistically significant difference. Conclusion In the central part of China, the majority of inpatients with glaucoma was PACG. It may relate to the regional,economic and cultural conditions.

The intestine is the largest immune and metabolic site in the body and is thus important for animal health.The integrity of the mucosal barrier and function are fundamental factors protecting the health of the intestine.Stress has been reported to have profound effects on the gastrointestinal tract,including altering gut permeability,the intestinal barrier,and homeostasis.Tryptophan is a functional essential amino acid that alters the gut microbiota and regulates intestine structural and functional change,thus contributing to host physiology and metabolism.Changes in tryptophan metabolism and its metabolites in brain and intestinal tissues during stress suggest that tryptophan may play an important role in the stress response.We therefore review the literature on the mechanisms underlying stress-related diseases and the role of tryptophan metabolism in the regulation of gut homeostasis,with particular focus on functional bowel disorders and their relationship to stress,to provide a theoretical foundation for targeting tryptophan in stress-related intestine diseases.

Objective: To investigate the therapeutic effects of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with FLAG sequential busulfan/cyclophosphamide(Bu/Cy) conditioning regimen for refractory/relapsed acute myeloid leukemia. Methods: From February 2012 to June 2017, 21 patients with refractory/relapsed acute myeloid leukemia underwent allo-HSCT with FLAG sequential Bu/Cy conditioning regimen. Transplantation-related complications and clinical outcome were retrospectively analyzed. Results: After conditioning, no hepatic veno-occlusive disease (VOD) and grade Ⅲ hemorrhagic cystitis occurred. 76.2% (16/21) patients had fever with 4 septicemia. One patient died of septic shock before engraftment. Twenty patients achieved neutrophil engraftment with a median time of 13 days (range, 10 to 21 days). Seventeen patients achieved platelet engraftment with a median time of 18 days (range, 9 to 25 days). The cumulative incidence of acute graft-versus-host disease (aGVHD) was 39.5%, and 3 patients developed grade Ⅲ-Ⅳ aGVHD. Of 19 patients who survived more than 100 days after transplantation, 4 had local chronic graft-versus-host disease (cGVHD). Of 21 patients, the median survival time was 15 months (range, 0.5 to 67 months) post-transplantation. Transplantation-related mortality rate was 28.7%. Leukemia relapse occurred in 4 patients with a median time of 4 months (range, 3 to 8 months) after transplantation. The cumulative relapse rate at 1 year was 21.4%. The 1-year and 3-year overall survival (OS) rates were 60.7% and 54.9% respectively. Log-rank analysis revealed that bone marrow blasts ≥ 20% or extramedullary leukemia before transplantation, poor platelet engraftment and grade Ⅲ-Ⅳ aGVHD were significantly related to shortened OS (P<0.05). Conclusions Allo-HSCT with FLAG sequential Bu/Cy conditioning regimen in patients with refractory/relapsed myeloid leukemia has acceptable transplantation-related risk and relapse rate. The 1-year and 3-year OS rates are comparable with those in remission patients.

Objective:To reconstruct the three-dimensional (3D) dose distribution in radiotherapy based on the convolutional neural networks (CNN) through multi-perspective scintillation light processing.Methods:First, fluorescence images were captured from three orthogonal perspectives using a complementary metal-oxide-semiconductor (CMOS) imaging sensor. Then, the images were converted into 3D images, which were input to the trained CNN for dose reconstruction. Finally, the reconstructed doses in different fields were evaluated in terms of gamma pass rate, mean-square error (MSE), percentage depth dose (PDD), and cross beam profile (CBP). Additionally, as the CNN model, 3D-Unet was pre-trained on a virtual dataset.Results:With the 50% maximum dose of as the threshold and 3%/3 mm as the standard, the central-plane and stereo-mean gamma pass rates of all field reconstruction distributions were over 90%, with MSEs remained below 1%. Besides, the PDD and CBP curves showed MSEs below 1‰ and below 1%, respectively.Conclusions:The deep learning-based method for 3D dose reconstruction using scintillation light contributes to enhanced verification of instantaneous 3D relative dose based on plastic scintillation detectors.

Objective To explore the relationship between the expression levels of serum cingulate protein(CGN)and polyligand glycan 1(SDC-1)and the disease condition and outcome of hypertensive basal ganglia hemorrhage(HBGH).Methods A total of 123 patients with HBGH admitted to the Second People's Hospi-tal of Lianyungang from February 2019 to February 2022 were selected as the study objects,and 120 healthy volunteers who underwent physical examination in the hospital during the same period were selected as the health group.Serum CGN and SDC-1 expression levels were detected in the two groups.According to the dis-ease outcome,the patients were divided into the improved group(92 cases)and the deteriorated group(31 ca-ses).Receiver operating characteristic(ROC)curve and the area under the curve(AUC)were used to analyze the predictive value of serum CGN and SDC-1 expression levels on the disease outcome of patients with HB-GH.Results Serum CGN and SDC-1 expression levels in the severe group were higher than those in the mod-erate group and the mild group,and serum CGN and SDC-1 levels in the moderate group were higher than those in the mild group,and the differences were statistically significant(P＜0.05).Serum CGN and SDC-1 expression levels in HBGH patients in three groups were higher than those in health group,and the differences were statistically significant(P＜0.05).Serum CGN and SDC-1 expression levels in the deteriorated group were higher than those in the improved group,and the differences were statistically significant(P＜0.05).The AUC of serum CGN and SDC-1 for predicting the disease outcome of HBGH patients was 0.742(95％CI:0.792-0.697)and 0.861(95％CI:0.906-0.910),respectively,and the AUC of the combination of the two was 0.917(95％CI:0.962-0.870).The amount of blood loss and ventricular rupture in the deteriorated group were higher than those in the improved group,and the Glasgow Coma Scale(GCS)score on admission was lower than that in the improved group,and the differences were statistically significant(P＜0.05).Multi-variate Logistic regression analysis showed that serum CGN≥51.63 pg/mL(OR=3.815),serum SDC-1≥450.67 μg/L(OR=4.230)and GCS score ≤8(OR=5.333)were the influencing factors for disease outcome of HBGH patients(P＜0.05).Conclusion The increased expression levels of serum CGN and SDC-1 are closely related to the disease aggravation and the deterioration of the disease outcome in patients with HBGH,and they have certain predictive value for the disease outcome in patients with HBGH.
