OBJECTIVETo adopt a criterion summarized in long-term practice to judge the immune status of recurrent aphthous ulceration (RAU) patients, and to analyze its rationality and feasibility.

METHODS60 cases were included, whose clinical information, such as age, sex, constitution status, history of system diseases and severity of ulceration were collected. The subjective judgement results of the immune status were obtained according to the criterion summarized in clinical practice. At the same time, peripheral blood parameters about immune function were examined in order to obtain the objective examination results of the immune status. With the examination result as the gold standard, the rationality of the criterion was estimated through its sensitivity and specificity.

RESULTSAccording to subjective judgment, there were 86.67% cases with abnormal immune status (28.33% cases with elevated immune status, and 58.33% cases with reduced immune status). According to objective examination, there were 93.33% cases with abnormal immune status (23.33% cases with elevated immune status, and 70.00% cases with reduced immune status. Sensitivity and specificity were 89.29% and 50.00% when the criterion was used to judge immune abnormality, 42.86% and 76.09% when the criterion was used to judge immune elevation, and 64.29% and 55.56% when the criterion was used to judge immune reduction.

CONCLUSIONIt is of some rationality and feasibility to judge the immune status according to the criterion based on clinical information, and the criterion can be used in small clinics.

This study was aimed to construct nucleic acid vaccine containing the coding region of the CML28 gene and to express it in human dendritic cells. The full length of CML28 cDNA was amplified from K562 by RT-PCR and subcloned into pGEM-T vector. The CML28 fragment was digested and subsequently inserted into the EcoRI-Xba I sites of pcDNA3.1HisA to construct the recombinant expression vector pcDNA3.1HisA-CML28, which was identified by restrition analysis and sequencing. Human dendritic cells (DC) were separated from peripheral blood mononuclear cells (PBMC) by culture with rhGM-CSF, rhIL-4 and assessed by flow cytometry. The constructed plasmid pcDNA3.1 HisA-CML28 was transfected into DC by electroporation. Western blot was used to detect the expression of fusion protein His-CML28. The results showed that recombinant plasmid pcDNA3.1HisA-CML28 contained the correct full CML28 cDNA identified by restriction analysis and sequencing, and can express the fusion protein His-CML28 in DCs. It is concluded that nucleic acid vaccine containing CML28 gene was constructed and expressed in DC successfully.

The purpose of this study was to construct a HA-1-DC nucleic acid vaccine and to induce anti-leukemia effect after hematopoietic stem cell transplantation (HSCT). The dendritic cells (DCs) were generated from HSCT donors in vitro, and its immunologic activity was studied by using flow cytometry and mix lymphocyte reaction. HA-1 gene was electroporated into the cultured DCs to construct a DC nucleic acid vaccine. After transfecting for 48 hours, the expression of HA-1 protein was detected by Western blot. The DCs were cultured with isogenic lymphocytes to induce specific cytotoxic T lymphocytes (CTLs). The cytotoxicity of the CTLs was detected by LDH assay. The results showed that the DCs derived from peripheral blood monocytes (PBMCs) expressed the DC phenotype, and were effective in stimulating proliferation of the allogenic lymphocytes. After electroporating for 48 hours, HA-1 protein was detected by Western blot. The cytotoxity of inducing CTLs was higher than that in the control group. It is concluded that the minor histocompatibility antigen HA-1 can be considered as a target of immunotherapy against leukemia after HSCT.

PURPOSE: To investigate the clinical value of urine interleukin-18 (IL-8), neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) for the early diagnosis of acute kidney injury (AKI) in patients with ureteroscopic lithotripsy (URL) related urosepsis. METHODS: A retrospective study was carried out in 157 patients with urosepsis after URL. The patients were divided into AKI group and non-AKI group according to the Kidigo guideline and urine IL-8, NGAL and KIM-1 levels were detected by enzyme-linked immunosorbent assay at 0, 4, 12, 24 and 48 h after the surgery. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic value of these three biomarkers for postoperative AKI. RESULTS: The level of urine IL-8, NGAL and KIM-1 in AKI group was significantly higher than that in non-AKI group at 4, 12, 24 and 48 h (p < 0.01). The ROC analysis showed the combined detection of urine IL-8, NGAL and KIM-1 at 12 h had a larger area under curve (AUC) than a single marker (0.997, 95% CI: 0.991-0.998), and the sensitivity and specificity were 98.2% and 96.7%, respectively. Pearson correlation analysis showed that the levels of urine NGAL at 4, 12, 24 and 48 h in AKI patients were positively correlated with the levels of urine KIM-1 and IL-18 (p < 0.01). CONCLUSION AKI could be quickly recognized by the elevated level of urine IL-8, NGAL and KIM-1 in patients with URL-related urosepsis. Combined detection of the three urine biomarkers at 12 h after surgery had a better diagnostic performance, which may be an important reference for the early diagnosis of AKI.

To clarify the key quality attributes of substance benchmarks in Danggui Buxue Decoction(DBD), this study prepared 21 batches of DBD substance benchmarks, and established two methods for detecting their fingerprints, followed by the identification of peak attribution and similarity range as well as the determination of extract and transfer rate ranges and contents of index components ferulic acid, calycosin-7-O-β-D-glucoside, and astragaloside Ⅳ. The mass fractions and transfer rates of DBD substance benchmarks from different batches were calculated as follows: ferulic acid(index component in Angelicae Sinensis Radix): 0.037%-0.084% and 31.41%-98.88%; astragaloside Ⅳ(index component in Astragali Radix): 0.021%-0.059% and 32.18%-118.57%; calycosin-7-O-β-D-glucoside: 0.002%-0.023% and 11.51%-45.65%, with the extract rate being 18.4%-36.1%. The similarity of fingerprints among 21 batches of DBD substance benchmarks was all higher than 0.9. The quality control method for DBD substance benchmarks was preliminarily established based on the HPLC fingerprint analysis and index component determination, which has provided a basis for the subsequent development of DBD and the quality control of novel related preparations.

To enhance the clinical applicability of guidelines and provide more effective guidance for clinical practice, a clinical value assessment was conducted during the development of the World Federation of Acupuncture-Moxibustion Societies (WFAS) Clinical Practice Guideline of Acupuncture and Moxibustion for Migraine, which involved the evaluation of 59 acupuncture and moxibustion treatment protocols from randomized controlled trials (RCTs). This article introduced the methodology, content and results of the clinical value assessment of RCT-based acupuncture and moxibustion treatment protocols, which involved the integration of historical and contemporary medical evidence and expert consensus. It served as a methodological reference for the future development of acupuncture and moxibustion clinical practice guidelines.
