Objective To investigate the variation of immune index in patients with systemic lupus erythematosus (SLE) treated with autologous purified CD+34 cells transplantation and to clarify the relationship with pathogenesis and prognosis. Methods Flow cytometry (FCM) and enzyme linked immunosorbent assay(ELISA) were used to test lymphocyte subsets, C3, C4, CH50, autoantibodies and immunoglobulin for 18 cases of SLE before and after transplantation. Results The results showed that the ratio of all the T cell subsets reduced obviously in early postgraft and recovered gradually in 1 to 3 months after transplantation except CD45 RO+CD+4 cells. The levels of serum C3, C4, CH50 increased significantly after transplantation. No case relapsed within one year after transplantation, but 2 patients relapsed one year after transplantation. The levels of the indexes in the patients with relapse were significantly lower than those in the patients with persistent remission, including C4 in the entire course, CH50 in the 3rd and 12th month after transplantation and CD45 RA+ CD+8 cells in the 6th month after transplantation. However, the ratio of CD45 RO+ CD+4 cells in the first month after transplantation in the patients with relapse was higher than that in the patients with persistent remission. Conclusion Autologous purified CD+34 cells transplantation is effective for treating SLE. Survey of immune indexes before and after transplantation is important to investigate the pathogenesis of SLE. Moreover, these immune indexes can be used to predict therapeutic efficacy of SLE.

The technique of liquisolid compress is a new technique developed in 1990s, which was considered to be the most promising technique to improve the dissolution of water-insoluble drugs. In this article, tanshinone II(A) and the extracts of the ester-solubility fractions were chosen as the model drugs to evaluate the effects of the liquisolid technique for enhancement of dissolution properties of tanshinone II(A). Several liquisolid tablets (LS) formulations containing different dosage of drugs and various liquid vehicle were pre-pared and for all the formulations, microcrystalline cellulose and silica were chosen as the carrier and coating materials to evaluate their flow properties, such as angle of repose, Carr's compressibility index and Hausner's ratio. The interaction between drug and excipients in prepared LS compacts were studied by differential scanning calorimetry(DSC) and X-ray powder diffraction (XRPD). The dissolution curves of tanshinone II(A) from liquisolid compacts were investigated to determine the technique's effect in improving the dissolution of tanshinone II(A) and its impacting factors. According to the results, the dissolution increased with the rise in the dissolution of the liquid-phase solvent. The R-value and drug dosage can significantly affect the drug release, but with less impact on active fractions. This indicated that liquisolid technique is a promising alternative for improvement of dissolution property of water-soluble drugs, and can make a synergistic effect with other ester-soluble constituents and bettern improve the release of tanshinone II(A). Therefore, the technique of liquisolid compress will have a better development prospect in traditional Chinese medicines.

Objective:To investigate the clinicopathological features of gastric adenocarcinoma of fundic gland type (GA-FG).Methods:A total of 12 patients, including 7 cases treated with endoscopic submucosal dissection (ESD), were diagnosed as having GA-FG in Nanjing Drum Tower Hospital from January 2018 to August 2019. Morphological changes were analyzed by reviewing endoscopic and pathological results. Patients were followed up after definitive diagnosis.Results:The clinical symptoms of patients with GA-FG were nonspecific. No Helicobacter pylori infection was identified. The lesions were found in the non-atrophic gastric mucosa of the upper 1/3 portion in 10 cases and middle 1/3 portion in 2 cases. Endoscopically, the most common features were whitish color (9 cases), and all lesions diameter≤1 cm. Their macroscopic types were classified as 0-Ⅰ (2 cases), 0-Ⅱa (9 cases) and 0-Ⅱc (1 case) respectively. All lesions had sharp boundary, with branching dilated blood vessels on the surface. Five in 7 cases who were treated with ESD showed submucosal invasion. Immunohistochemically, 9 cases were classified as the chief cell type , 3 as the mixed type, 11 MUC6 positive, 4 MUC5AC positive, 2 MUC2 positive, and 3 CD10 positive. P53 was detected in all 12 cases, and 9 cases had low Ki-67 staining index (<10%). The mean time of follow-up was 11 months, and 11 patients survived. Conclusion:GA-FG should be taken into consideration when the polyps are found in the upper part of the stomach, with whitish color, and branch dilated blood vessels on the surface. Excellent clinical outcomes can be achieved for GA-FG patients with ESD.

Objective To study the effect of inflammatory markers on the level of reactive oxygen species (ROS) and mitochondrial DNA (mtDNA) copy numbers in granulosa cells of patients without polycystic ovary syndrome (PCOS). Methods Fifty patients without PCOS treated with in vitro fertilization and embryo transfer (IVF-ET) were selected in this study. The granulosa cells were extracted and cultured in vitro. Cells were randomly divided into treatment group and control group. The 5 nmol/L interleukin (IL)-1, IL-6 and tumor necrosis factor (TNF)-αwere given to treatment group, and same amount of inflammatory diluted solution was added to control group. The levels of ROS and copy numbers of mtDNA were compared between two groups. Results The ROS levels and mtDNA copy number of granulosa cells were significantly higher in IL-1, IL-6 and TNF-αtreatment groups than those of control group (P<0.05). Conclusion Inflammatory markers of IL-1, IL-6 and TNF-αincrease the level of ROS and damage mtDNA in granulosa cells.
