Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

BACKGROUND: Psoriasis is a chronic inflammatory skin disease, affecting about 0.6% of the Chinese population. Many patients are not well controlled by conventional treatments, thus there is need for new treatment regimens. In this study, we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis. METHODS: This study was a 52-week, multicentre, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 trial. A sub-population of study participants (≥18 years) of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab, or placebo. The co-primary endpoints were psoriasis area severity index (PASI) 75 and Investigator's Global Assessment (IGA) 0/1 at Week 12. RESULTS: A total of 441 Chinese patients were enrolled in this study. Co-primary outcomes were achieved; 300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75 (97.7% and 87.2% vs. 3.7%, respectively; P < 0.001), and IGA 0/1 (82.3% and 69.7% vs. 2.7%; P < 0.001) at Week 12. Treatment efficacy was maintained until Week 52. There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period. CONCLUSION: Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis.

BACKGROUND: Benvitimod cream, a novel synthetic small molecule, was effective in treating mild-to-moderate plaque psoriasis. We conducted a phase III clinical trial to assess the efficacy and safety of benvitimod cream in patients with mild-to-moderate plaque psoriasis. METHODS: We randomly assigned 686 patients (2:1:1) to receive 1% benvitimod cream, 0.005% calcipotriol ointment or placebo twice a day for 12 weeks. The primary efficacy end points were the percentage of patients with a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI 75) score and with a score of 0 or 1 in static physician's global assessment (sPGA) at week 12. RESULTS: The results showed that 50.4% of patients in the benvitimod group achieved PASI 75, which was significantly higher than that in the calcipotriol (38.5%, P < 0.05) and placebo (13.9%, P < 0.05) groups. The proportion of patients achieving an sPGA score 0 or 1 was 66.3% in the benvitimod group and 63.9% in the calcipotriol group, which were both significantly higher than that in the placebo group (34%, P < 0.05). In the long-term follow-up study, 50.8% of patients experienced recurrence. After retreatment with 1% benvitimod, 73.3% of patients achieved an sPGA score of 0 or 1 again at week 52. Adverse events included application site irritation, follicular papules, and contact dermatitis. No systemic adverse reactions were reported. CONCLUSION: During this 12-week study, benvitimod cream was demonstrated with high effectiveness and safety in patients with mild-to-moderate plaque psoriasis.

OBJECTIVE: To investigate the clinicopathological features,treatment and prognosis of patients with papillary renal cell carcinoma (PRCC) and PRCC-complicated with tumor thrombus. METHODS: Single center retrospective analysis of 75 patients with PRCC treated from January 2012 to October 2017 was performed. There were 55 males and 20 females at an age range of 24-82 years. Sixteen PRCC patients were complicated with tumor thrombus. All the patients were with a surgery and had clear pathological diagnosis and detailed follow-up data. The clinicopathological features, prognosis and influencing factors of the patients with PRCC and PRCC complicated with tumor thrombus were analyzed and summarized. RESULTS: The average age of the 75 patients was(56.05±11.59)years,the average body mass index (BMI) was (26±3) kg/m², and the average tumor maximum diameter was (5.17±3.85) cm. There were significant differences between tumor maximum diameter larger than 7 cm and less than 7 cm (69.6% vs. 94.4%, P<0.001), lymph node metastasis and no lymph node metastasis (<38% vs. 98%, P<0.001), adrenal metastasis and no adrenal metastasis (0% vs. 95.3%, P<0.001), pulmonary metastasis and no pulmonary metastasis (0% vs.90.7%, P<0.001), complicated with and without tumor thrombus (<66.4% vs. 93.5%, P<0.001) on the effect of 3-year survival rate of the PRCC patients. In this study, there were 16 patients with type 2 PRCC complicated with tumor thrombus. There were significant differences in concomitant symptoms (62.5% vs. 22.0%, P=0.005), maximum tumor diameter (68.8% vs.13.3%, P<0.001), adrenal metastasis (18.8% vs. 0.02%, P=0.029), pulmonary metastasis (18.8% vs. 0%, P=0.008), nuclear grade (P<0.001) and pathological type (100% vs. 44.1%, P<0.001) between the PRCC patients with and without tumor thrombus. CONCLUSION There were significant differences in tumor diameter,lymph node metastasis,adrenal metastasis, pulmonary metastasis,pathological type, nuclear grade and tumor thrombus in the effect of the 3-year survival rate of PRCC patients. PRCC patients with tumor thrombus were more commonly suffered from type 2 PRCC, for whom the tumor diameter was larger,the nuclear grade was higher,and the distance metastasis happened more easily.

OBJECTIVE: To investigate the safety and feasibility of laparoscopic treatment for renal carcinoma with Mayo 0-2 level venous thrombosis. METHODS: From January 2015 to February 2018, 58 renal carcinoma cases with venous thrombus underwent laparoscopic radical nephrectomy with inferior vena cava thrombectomy in Department of Urology, Peking University Third Hospital, of which, 51 cases were male, and 7 female, aged 29-82 years. According to the Mayo grade classification, 20 cases were level 0, 20 cases were level 1, and 18 cases were level 2, with left side being 22 cases, and right side 36 cases. The patients except for those complicated with hemorrhagic diseases, cardiac and pulmonary insufficiency, or those who could not tolerate anesthesia and surgical contraindications, underwent the operation after comprehensive examinations. RESULTS: The 58 cases of renal tumor with venous tumor emboli were successfully completed with the surgeries, including 50 cases of totally laparoscopic surgery, 8 cases of laparoscopy surgery from convert to open (among the patients who were converted to open surgery, 7 were complicated with grade 2 tumor thrombus and 1 with grade 1 tumor thrombus). The main reasons for converting to open surgery were huge tumors (the largest of which was about 16 cm in diameter), severe adhesion and difficulty of separation. For different patients, different surgical methods and procedures were adopted according to the tumor direction and the different grade of tumor thrombus. Radical nephrectomy combined with vena cava tumor thrombus removal was performed in 55 cases and segmental resection of vena cava in 3 cases. The operation time was 132-557 min, and blood loss was 20-3 000 mL. Post-operative pathological types: 51 cases were clear cell carcinoma, 5 cases were type 2 of papillary carcinoma, 1 case was squamous cell carcinoma, and 1 case was chromophobe cell tumor. In the study, 47 cases were followed up for 1-36 months, and 4 cases died (the survival time was 5-15 months, with an average of 10.2 months). CONCLUSION Laparoscopic radical nephrectomy with inferior vena cava thrombectomy is a reasonable choice for renal tumor with Mayo 0-2 level venous thrombosis. For different tumor directions and different grades of tumor thrombus, an appropriate operation plan can give the maxim benefit to the patients with skillful surgeons.

OBJECTIVETo investigate the clinical features and prognosis of bone metastases in colorectal cancer patients.

METHODSThe clinical data of 104 cases of colorectal cancer with bone metastasis were collected and retrospectively analyzed.

RESULTSAmong all the 104 patients included, 45 (43.3%) patients had multiple bone metastases, and 59 (56.7%) patients had single bone metastasis. Pelvis (46.1%) was the most common site, followed by thoracic vertebrae (41.3%), lumbar vertebrae (40.4%), sacral vertebrae (29.8%) and ribs (29.8%). One hundred and two patients (98.1%) were complicated with other organ metastases. The median time from colorectal cancer diagnosis to bone metastasis was 16 months, and the median time from bone metastasis to first skeletal-related events (SREs) was 1 month. The most common skeletal-related events (SREs) were the need for radiotherapy (44.2%), severe bone pain (15.4%) and pathologic fracture (9.6%). The median survival time of patients with bone metastases was 10.0 months, and 8.5 months for patients with SREs. ECOG score, systemic chemotherapy and bisphosphonate therapy were prognostic factors by univariate analysis (all P < 0.05). ECOG score and systemic chemotherapy were independent prognostic factors by Cox multivariate analysis.

CONCLUSIONSBone metastasis in colorectal cancer patients has a poor prognosis and the use of chemotherapy and bisphosphonates may have a benefit for their survival.

BACKGROUNDFunctional neuroimaging study has opened an avenue for exploring the pathophysiology of cluster headache (CH). The aim of our study was to assess the changes in brain activity in CH patients by the regional homogeneity method using resting-state functional magnetic resonance imaging technique.

METHODSThe functional magnetic resonance imaging scans were obtained for 12 male CH patients with spontaneous right-sided headache attacks during "in attack" and "out of attack" periods and 12 age- and sex-matched normal controls. The data were analyzed to detect the altered brain activity by the regional homogeneity method using statistical parametric mapping software.

RESULTSAltered regional homogeneity was detected in the anterior cingulate cortex, the posterior cingulate cortex, the prefrontal cortex, insular cortex, and other brain regions involved in pain processing and modulation among different groups.

CONCLUSIONIt is referred that these brain regions with altered regional homogeneity might be related to the pain processing and modulation of CH.

BACKGROUNDThe role of B-cell remains an enigma in the pathogenesis of ankylosing spondylitis (AS). This study aimed to investigate the distributions of B-cells and subsets in peripheral blood of AS patients and observe their changes in etanercept-treated AS patents.

METHODSWe detected the proportions of CD19(+) B-cell, naive B-cell (CD19(+)CD27-), memory B-cell (CD19(+)CD27dim) and plasmablast (CD19(+)CD27high) in peripheral blood of 66 patients with AS (39 at active stage, 27 at stable stage; 35 patients with peripheral joint involvement, 31 patients with axial involvement alone), 30 patients with rheumatoid arthritis (RA) and 30 healthy volunteers using flow cytometry. And then we observed the changes of the above indexes of 39 active AS patients treated with etanercept in a randomized, double-blind, placebo-controlled trial.

RESULTS(1) Percentages of CD19(+) B-cells in active or peripheral joint involvement AS patients increased more obviously than those in stable or axial involvement alone AS patients (both P = 0.001), and percentage of CD19(+)CD27high B-cells in AS patients with peripheral joint involvement was significantly higher than that in cases with axial involvement alone or healthy volunteers (P = 0.005 and 0.006, respectively); (2) The percentage of CD19(+) B-cells in AS patients was positively correlated with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores, Patient's Global Assessment (PGA) scores, total back pain scores and nocturnal back pain scores (r = 0.270, 0.255, 0.251 and 0.266, P = 0.029, 0.039, 0.042 and 0.031, respectively); (3) At week 6 and week 12, there were no statistical differences of the percentages of B-cells and subsets between etanercept group and placebo group of AS patients (P > 0.05); the percentage of CD19(+) B-cells in etanercept group was higher than that in healthy volunteers at week 12 (t = 3.320, P = 0.003).

CONCLUSIONSMisbalance is present in B-cells and some subsets in peripheral blood of active AS patients with peripheral joint involved. B-cells might play an important role in the pathogenesis of AS patients. The high percentage of CD19(+) B-cells in active AS patients cannot be down-regulated after 12-week etanercept treatment.
