In order to optimize the data flow of subject datasets and to establish the service platform of medical image data, we developed a medical image database aiming at subject service of clinic research. Firstly, a novel integrated infrastructure was designed, which was based on the requirements of database system and the survey of data resource. Then, several standards and technologies had been used in the construction of this novel system, including "Subject dataset-Sample data-Image files" three-ties image information framework, DICOM-based data processing, Index & file hybrid structure of file management strategy, etc. The new system has been successfully deployed in our test-bed and has got satisfactory results.

In this paper, the theory of complex adaptive system (CAS) and its modeling method are introduced. The complex characters of the hospital system is analyzed. The agile manufacturing and cell reconstruction technologies are used to reconstruct the hospital system. Then we set forth a research for simulation of hospital system based on the methodology of Multi-Agent technology and high level architecture (HLA). Finally, a simulation framework based on HLA for hospital system is presented.

To assess relationships between xanthine oxidase (XOD) and nephropathogenic infectious bronchitis virus (NIBV) infection, 240 growing layers (35 days old) were randomly divided into two groups (infected and control) of 120 chickens each. Each chicken in the control and infected group was intranasally inoculated with 0.2 mL sterile physiological saline and virus, respectively, after which serum antioxidant parameters and renal XOD mRNA expression in growing layers were evaluated at 8, 15 and 22 days post-inoculation (dpi). The results showed that serum glutathione peroxidase and superoxide dismutase activities in the infected group were significantly lower than in the control group at 8 and 15 dpi (p < 0.01), while serum malondialdehyde concentrations were significantly higher (p < 0.01). The serum uric acid was significantly higher than that of the control group at 15 dpi (p < 0.01). In addition, the kidney mRNA transcript level and serum activity of XOD in the infected group was significantly higher than that of the control group at 8, 15 and 22 dpi (p < 0.05). The results indicated that NIBV infection could cause the increases of renal XOD gene transcription and serum XOD activity, leading to hyperuricemia and reduction of antioxidants in the body.

Objective:This study aims to explore the clinical characteristics of T-cell large granular lymphocyte leukemia (T-LGLL) patients with STAT3 mutation status and provide a reference for clinical management of such patients.Methods:The clinical data of T-LGLL patients between 2009 and 2019 in Jiangsu Province Hospital were retrospectively analyzed. Differences in baseline clinical data, treatment responses, and survival outcomes in patients with STAT3 mutations or with no mutations were compared.Results:A total of 80 patients were included, including 66 patients without STAT3 mutation and 14 patients (17.5%) with STAT3 mutation. The frequency of Y640F mutation was the highest (42.9%) . Compared with non STAT3 mutation group, STAT3 mutation group had lower HGB (67.5 g/L vs 82.5 g/L, P=0.018) , lower neutrophil count (0.665×10 9/L vs 1.465×10 9/L, P<0.001) , higher LDH (229 U/L vs 198 U/L, P=0.041) , higher ferritin (402.5 g/L vs 236.0 g/L, P=0.029) , higher expression rate of TCR Vβ subfamily (89.2% vs 65.4%, P=0.014) and higher proportion of patients with treatment indications (100% vs 74%, P=0.033) . The complete remission rates of STAT3 mutation group and non mutation group were 38.5% and 32.7%, respectively, with no significant difference ( P=0.748) . The overall response rate of first-line immunosuppressive therapy in STAT3 mutation group and non mutation group were 69.2% and 69.4%, respectively, with no significant difference ( P=1.000) . The median follow-up time was 63 (2-121) months. There was no significant difference in the overall survival time between the two groups ( P=0.170) . Conclusions:T-LGLL patients with STAT3 mutations seems to be correlated with an increased tumor burden and high treatment demand, and had a good response to first-line immunotherapies. The prognostic significance of STAT3 mutation in T-LGLL patients requires further validation.

Objective:The study aimed to analyze the clinical features and prognosis of chronic lymphocytic leukemia (CLL) with t (14;18) (q32;q21) and conduct a literature review.Methods:The clinical data of 8 patients with CLL carrying t (14;18) (q32;q21) seen in Jiangsu Province Hospital from November 2009 to November 2019 were collected and analyzed.Results:Among the 8 cases, 7 were male and 1 was female. The median age at diagnosis was 70 years old. The immunophenotype score was 5 in 3 patients. 4 patients were scored 4 and the remaining one scored 3. The bone marrow histopathology showed the typical manifestation of CLL. Karyotype analysis showed that all the cases carried t (14;18) (q32;q21) in the stemline. The t (14;18) (q32;q21) showed as the sole abnormality in 3 cases, with +12 in 4, and with 13q- in 1 case. 13q- was found in another 3 patients by FISH. Immunoglobulin heavy chain gene (IGHV) mutation status was detected in 6 cases and all of them were mutated. None of them used IGHV3-21. Only 1 case harbored TP53 mutation and no TP53, SF3B1, NOTCH1, or MYD88 mutations were found in the remaining cases who underwent the relevant tests. At a median follow-up of 30.9 months, 1 case died. The remaining 7 cases survived and 3 of them have not reached the treatment indication. 4 patients who received chemotherapy or immunotherapy were stable.Conclusions:The t (14;18) (q32;q21) is rare in CLL and often accompanied by +12 and mutated IGHV. CLL with t (14; 18) (q32; q21) tends to have a good prognosis.

Standardization is the universal language of the world, and standardization of traditional Chinese medicine (TCM) is essential for its communication in China and globally. However, the principles and methods of TCM acupuncture standardization have been unclear and inadequate in the early stages. Based on an investigative approach to understanding the current status, identifying problems, and finding solutions, our team has established basic principles of TCM acupuncture that embody Chinese wisdom, evaluated the international strategic environment systematically, proposed the principle of “importance of harmony and exercise of impartiality”, and established basic working principles. A series of methods for TCM acupuncture standard development and evaluation have been constructed, including general standards for the revision of TCM acupuncture standards, the first TCM acupuncture clinical research management specification, a shared full chain technology platform, a data center, and an evaluation research base for TCM acupuncture clinical research. Evaluation criteria for ancient literature and expert experience, a recommendation method for the “three main and three auxiliaries” TCM guideline for prevention were established, and quantifiable assessment methods of TCM standard applicability were proposed. These findings provide methodological guidance for TCM acupuncture standardization.
