OBJECTIVETo explore the effects of chronic exposure to trace chromium (VI) as a result of metal-on-metal hip arthroplasty on oxidative stress in mouse liver cells.
METHODSEighty NIH mice were randomly divided into 4 groups and subject to intraperitoneal injection of CrO(3) at the dose of 0, 5, 10 or 20 mg/kg every other day for 16 weeks. Five mice from each group were selected every 4 weeks for determining the content of chromium (VI) in the whole blood and the levels of reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH), glutathione reductase (GR) activity, and glutamate cysteine ligase (GCL) expression in the liver cells. The ultrastructural changes of the liver cells were also observed using transmission electron microscopy.
RESULTSExposure to 5 and 10 mg/kg CrO(3) caused significantly increased blood chromium concentration and ROS level, which reached the peak level at 8 weeks and became stabilized, whereas at the dose of 20 mg/kg, CrO(3) exposure resulted in progressive, time-dependent increase of blood chromium concentration and ROS level. MDA showed no significant changes in the 4 groups. With the prolongation of the exposure time, GSH content and GR activity were decreased in these groups. In 5 and 10 mg/kg CrO(3) groups, GCL expression increased at each time point of measurement, but in 20 mg/kg group, GCL expression decreased gradually with a prolonged exposure. Transmission electron microscopy revealed apoptotic changes of the liver cells in 20 mg/kg group.
CONCLUSIONThe slow accumulation of trace chromium (VI) after metal-on-metal hip arthroplasty may cause oxidative stress and changes in the oxidative stress system in the liver cells.

Objective This study aimed to assess the diagnostic value of anti-mutated citrullinated vimentin (MCV) antibodies in rheumatoid arthritis (RA) and its correlation with disease progression, extra-articular manifestations and overlap syndrome. Methods Retrospective Studies. Clinical data of 837 patients in PekingUnionMedicalCollegeHospitalfrom June to August 2017 were collected, including the result of anti-MCV, anti-cyclic citrullinated peptide (anti-CCP) antibodies, rheumatoid factor (RF), erythrocyte sedimentation rate (ESR) and High-sensitivity-C-reactive protein (CRP). According to the 1987 American College of Rheumatology classification criteria for rheumatoid arthritis, there were 323 patients diagnosed with RA, including 59 males and 264 females with the average age of 51 years. According to whether the RA patients have overlap syndrome with other autoimmune disease (AID) or have extra-articular manifestations, 258 cases were categorized into RA group, including 47 males and 211 females with the average age of 50 years; 14 cases were categorized into the group of overlap syndrome, including 1 male and 13 females with the average age of 36 years;51 cases were categorized into the group of extra-articular manifestations, including 11 males and 40 females with the average age of 59 years.According to 2010 rheumatoid arthritis classification criteria for destruction in joints, the radiographic changes were divided into 4 stages. There were 203 casesenrolled in our study, 88 caseswere fitted into early stage group (stage I)including 21 males and 67 females with the average age of 48 years; 115 caseswere fitted into progressive stage group, which compromisedstageⅡ (interim stage), stage Ⅲ (severe stage) and stage Ⅳ(final stage) cases, including 19 males and 96 females with the average age of 53 years. Mann-Whitney U test, x2 test, Receiver operating characteristic (ROC) curves and Spearmancorrelation coefficientwere used in Statistical analysis. Results Ⅰ Amongdiagnosed RA patients, 199 (61.6%) cases were positive for anti-MCV, anti-CCP and RFsimultaneously, 42 (13%) cases were positive for anti-MCV, which was higher than anti-CCP positive (1 cases, 0.3%) or RF positive (7cases, 2.2%). The difference was statistically significant(P<0.001, P<0.001). ⅡROC was calculated and MCV=35.95 U/ml was used as best-fit cut-off value. The AUC for anti-MCV was 0.867, while the sensitivity was 80.5%and specificity was 80.9%.ⅢThe detection levels of anti-MCV (682.8 (106.4-1000.0)), anti-CCP (407 (4.0-1536.0)) and RF (82.8 (21.1-244.9)) in the group of progressive stage were higher than those in the group of early stage (114.5 (28.5-1000.0), 62.5 (5.0-1020.7), 50.1 (6.7-127.1)), which showed a significant difference(P<0.05, P<0.05, P<0.05). The anti-MCV, anti-CCP and RF were positively related to the degree of joint destruction (r=0.229, P<0.05;r=0.187, P<0.05;r=0.167, P<0.05);anti-MCV and anti-CCP were positively related to extra-articular manifestation (r=0.152, P<0.05;r=0.136, P<0.05). Conclusion Anti-MCV antibodies are more sensitive in patients with RA, and have complementary diagnostic value for anti-CCP and RF-negative patients; high levels of anti-MCV and anti-CCP in RA patients are associated with RA progression and extra-articular involvement.

Objective To investigate the expression levels of scf and c-kit under the regulation of Dahuang Lingxian prescription and the possible mechanism of its effect on gallbladder dynamics, and to provide a theoretical basis for Dahuang Lingxian prescription in preventing the development and recurrence of cholesterol gallstone. Methods A total of 45 specific pathogen-free healthy male guinea pigs were randomly divided into normal group, model group, and traditional Chinese medicine (TCM) group. The guinea pigs in the normal group were fed with normal diet, and those in the model group and the TCM group were fed with high-fat lithogenic diet. After 8 weeks of feeding, 5 guinea pigs were randomly selected from each group, and successful modeling was determined if gallstone was observed with the naked eye in more than 4 guinea pigs. After successful modeling, the guinea pigs in the TCM group were given Dahuang Lingxian prescription by gavage, and those in the model group were given an equal volume of normal saline by gavage. After 8 consecutive weeks of administration by gavage, gallbladder tissue samples were collected, and HE staining was used to observe the pathological changes of gallbladder tissue; Western blot was used to measure the expression level of tumor necrosis factor-α (TNF-α) in gallbladder tissue; immunohistochemistry was used to measure the protein expression levels of scf and c-kit in gallbladder smooth muscle tissue. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference multiple comparison method was used for further comparison between two groups. Results HE staining showed marked inflammation of gallbladder tissue in the model group, and compared with the model group, the TCM group had a significantly lower degree of inflammation. Western blot showed that the model group had the highest expression level of TNF-α in gallbladder tissue, followed by the TCM group and the normal group ( P < 0.05); immunohistochemistry showed that compared with the model group, the normal group and the TCM group had significantly higher protein expression levels of scf and c-kit in gallbladder smooth muscle tissue ( P < 0.05). Conclusion Dahuang Lingxian prescription can enhance the dynamic function of the gallbladder, possibly by upregulating the scf/c-kit signaling pathway in interstitial cells of Cajal in gallbladder.
