ABSTRACT
Objective To report 3 cases of multiple myeloma (MM) with lung cancer.Combined with litera-ture review to improve the understanding of MM with lung cancer.Methods The clinical characteristics,treatment and prognosis of 3 cases of MM with lung cancer in Shijingshan Teaching Hospital of Capital Medical University from January 2017 to December 2018 and the relevant literature were retrospectively reviewed. Results Among the 3 patients,2 cases were male and 1 case was female,with an average age of 69.7 years.The pathological type of lung cancer patients was adenocarcinoma,of which 2 cases were positive for EGFR gene mutation and 1 case was positive for ALK fusion gene.Three cases of multiple myeloma were all IgG-kappa light chain type,with stage Ⅲ A.The chemotherapy regimens used in MM patients were all PD regimen 4-6 cycles; one patient died of pulmonary infec-tion,one patient had MM CR,but lung cancer progressed,one patient had MM very good partial remission (VGPR), and there was no recurrence of lung cancer.Conclusion The pathogenesis of second primary malignancy in MM is not clear,which needs further study.
ABSTRACT
Objective To investigate the immune status characteristics of primary ITP patients with abnor-mal auto-antibodies. Methods A total of 110 patients were enrolled in our study,who were admitted in Fu-Xing Hospital affiliated to Capital Medical University from January 2001 to July 2015.According to whether the patients have autoimmune diseases and the presence of auto-antibodies,we divided the patients into 3 groups,including the primary ITP with abnormal auto-antibodies(PITP-ANA)group,the primary ITP(PITP)group and the second-ary ITP(SITP)group.We compared the T-cell subsets,regulatory T cells,B lymphocytes,changes of immunoglob-ulin and bone marrow biopsy and cytology of patients among the three groups,retrospectively. Results The per-centage of CD3+T cells(61.72 ± 10.60)% in PITP-ANA group was lower than that in PITP group(69.57 ± 11.99)%. The percentage of CD8+T lymphocyte(24.00 ± 7.67)% was significantly lower than that of PITP group (30.59 ± 11.08)%(P<0.05).The proportion of Treg in PITP group,PITP-ANA group and SITP group were(6.12 ± 1.41)%,(7.50 ± 2.76)% and(8.49 ± 2.47)%,respectively,with statistically significant differences.The ra-tio of CD19+T cell in PITP-ANA group(25.75 ± 9.98)%was significantly higher than that in PITP group(16.16 ± 8.19)%(P < 0.01). The concentration of IgG、IgA、κ light chain and λ light chain in PITP group,PITP-ANA group and SITP group showed an upward trend and the highest level was in the SITP group,with statistically signifi-cant differences among the three groups. A variety of abnormal auto-antibodies could be found in both PITP-ANA group and SITP group. Conclusions We consider that the immune function abnormity of patients in PITP-ANA group were worse than that in PITP group,because the concentration of immunoglobulin,the percentage of B lym-phocyte and Treg ratio are higher in than those in PITP group.
ABSTRACT
Objective To investigate the relationship between vaspin,Apelin,leptin and polycystic ovary syndrome.Methods We determined the serum vaspin,Apelin and leptin levels of 40 cases of PCOS patients and 30 cases of control group,and divided the PCOS group into three subgroups (normal weight,overweight and obesity) according to WHO criteria for obesity.Then we compared the serum vaspin,Apelin and leptin levels in PCOS and control group,and the differences in body weight index (body mass index,BMI) in women with polycystic ovary syndrome,and analyzed roles of adipokine vaspin,Apelin and leptin in the pathogenesis of PCOS.Results In PCOS patients adipokine vaspin,Apelin,leptin,insulin resistance index (Homeostasis model assessment for insulin index in resistence,HOMA-IR),fasting insulin (INS) and blood glucose,blood lipid were higher than those of the control group and increased with the increase of body mass index (BMI),and three kinds of adipokines and PCOS patients with HOMA-IR were positively correlated,there were statistically significant differences (P ＜ 0.05).Conclusion The results of vaspin,Apelin and leptin may be involved in the occurrence of PCOS.
ABSTRACT
BACKGROUND: Osthol is a simple coumarin from Cnidium monnier (L.)Cusson which has been long used of in China as a herbal medicine for arthritis. We have previously observed protective effects of osthol on Ca2+antagonism, oxidative stress and inflammation. And other researches reported that it could inhibit increase of serum xanthine oxidase induced by liver tumor.OBJECTIVE: To investigate the protective effect of osthol on carbon tetrachloride (CCl4)-induced liver injury of mice.DESIGN: Completely randomized controlled study.SETTING: Department of Pharmacology, Gannan Medical College; Physical Education, Gannan Normal College.MATERIALS: A total of 40 Kunming mice were of both genders and weighing (20±2) g. Osthol was provided by Chengdu Longquan High-Tech Natural Pharmaceutical Co. Ltd.METHODS: The experiment was performed at Department of Pharmacology, Gannan Medical College from March to July 2005. Forty mice were randomly divided into control, model, osthol (ip 50 g/kg) and osthol (ip 100 g/kg) groups with 10 in each. Separately once a day for 15 consecutive days, the control and model groups were equalized injected intraperitoneally with 10 mL/kg saline and osthol groups injected intraperitoneally with 50 and 100 g/kg osthol, respectively. On 15 day just after treatment,they, except the control, were challenged with CCl4 (ip 1 g/L peanut oil solution 10 mL/kg). Then all mice were free access to water but fast food.At specified time points 16 hours after the injection of CCl4, all mice were sacrificed and blood was collected in centrifuge tubes. The serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and liver malondialdehyde (MDA) were determined, and the pathological examination of liver was observed.MAIN OUTCOME MEASURES: Contents of serum ALT, AST, MDA and pathological examination.RESULTS: Forty mice were involved in the final analysis. ① At 16 hours after CCl4 induction, contents of ALT and AST were higher in model group than those in control group (P ＜ 0.001). The increase in the contents of ALT and AST was inhibited by osthol in a dose-dependent manner, especially in 100 mg/kg osthol group (P ＜ 0.05). Both 50 mg/kg and 100 mg/kg osthol could inhibit the increase of AST induced by CCl4 (P ＜ 0.01-0.001).② Content of MDA in model group was increased (P ＜ 0.05), and content of MDA in 100 mg/kg osthol group was similar to that in control group.100 mg/kg osthol could decrease content of MDA, 50 mg/kg osthol could increased the content; however, it still had the tendency of decrease. ③Effect of osthol on histopahtological changes, the livers of CCl4intoxicated mice showed massive fatty change, gross necrosis, broad infiltration of the lymphocytes, and Kupffer cells around the central vein, loss of cellular boundary. The histological pattern of the livers of the mice treated with 100 mg/kg and 50 mg/kg osthol showed a mild degree of fatty change,necrosis and lymphocyte infiltration. In contrast, the inhibitory potency of 100 mg/kg osthol on the histological changes significantly higher than those models.CONCLUSION: Osthol can protect against CCl4-induced hepatotoxicity in mice through decreasing activities ALT and AST and contents of MDA.
