Abstract
The previous observational studies could not overcome the effects of confounding variables and reverse causality. We aimed to determine whether there is a causal relationship between systemic lupus erythematosus and osteoporosis in East Asian and European populations, respectively, by two-sample Mendelian Randomization analysis. We obtained and downloaded data from publicly available genome-wide association study databases and analyses for East Asian and European populations, including systemic lupus erythematosus (SLE), osteoporosis (OP), multisite bone mineral density (BMD), and OP with fracture. After screening for instrumental single-nucleotide polymorphisms (SNPs) significantly correlated to SLE, the inverse-variance weighted (IVW) method was used for calculating the ratio and 95% confidence interval, besides utilizing MR-Egger, weighted median, and weighted mode to assess the robustness of the primary outcome. Moreover, multiple analyses, including MR-PRESSO, MR-Egger intercept, Cochran's Q test, as well as "leave-one-out" sensitivity, were used for evaluating horizontal pleiotropy, heterogeneity, and stability. Finally, we exchanged exposure and outcome and performed a reverse MR analysis. IVW (OR = 1.05, 95% CI = 1.01-1.09, P = 0.009) indicated a significant positive correlation between genetically predicted SLE and OP in East Asians. Furthermore, neither heterogeneity nor horizontal pleiotropy was observed. In Europe, there was no significant genetically predicted causal relation between SLE and OP. Bi-directional MR analysis showed no reverse causality between SLE and OP. In the East Asian population, genetically predicted SLE may have had a positive causal relationship with OP. In Europe, there is insufficient evidence for a potential causal relation between SLE and OP or BMD and fracture, and the correlations currently observed may be attributed to a variety of confounder variables.

Abstract
Objective: To investigate the causative factors of renal function in newly diagnosed multiple myeloma (MM) patients with renal inadequacy. Methods: 181 MM patients with renal impairment from August 2007 to October 2021 at Peking Union Medical College Hospital were recruited, whose baseline chronic kidney disease (CKD) stage was 3-5. Statistical analysis was performed based on laboratory tests, treatment regimens, hematological responses, and survival among various renal function efficacy groups. A logistic regression model was employed in multivariate analysis. Results: A total of 181 patients were recruited, and 277 patients with CKD stages 1-2 were chosen as controls. The majority choose the BCD and VRD regimens. The progression-free survival (PFS) (14.0 months vs 24.8 months, P<0.001) and overall survival (OS) (49.2 months vs 79.7 months, P<0.001) of patients with renal impairment was considerably shorter. Hypercalcemia (P=0.013, OR=5.654) , 1q21 amplification (P=0.018, OR=2.876) , and hematological response over a partial response (P=0.001, OR=4.999) were independent predictive factors for renal function response. After treatment, those with improvement in renal function had a longer PFS than those without (15.6 months vs 10.2 months, P=0.074) , but there was no disparity in OS (56.5 months vs 47.3 months, P=0.665) . Conclusion: Hypercalcemia, 1q21 amplification, and hematologic response were independent predictors of the response of renal function in NDMM patients with renal impairment. MM patients with CKD 3-5 at baseline still have worse survival. Improvement in renal function after treatment is attributed to the improvement in PFS.

Abstract
Objective: Establishment of a new model of human primary colon cancer transplantation tumor in normal immune mice and to provide a reliable experimental animal model for studying the pathogenesis of colon cancer under normal immunity. Methods: Human colon cancer cells come from colon cancer patients who underwent surgery in the Affiliated Hospital of Jining Medical College in 2017. The mice in the cell control group were inoculated with phosphate buffered solution (PBS) containing colon cancer cells, the microcarrier control group was inoculated with PBS containing microcarrier 6, and the cell-microcarrier complex group was inoculated with the PBS containing colon cancer cell-microcarrier complex. The cells of each group were inoculated under the skin of the right axilla of mice by subcutaneous injection, and the time, size, tumor formation rate and pathological changes under microscope were recorded. The transplanted tumor tissue was immunohistochemically stained with the EnVisiion two-step method, and the tumor formation rate of the transplanted tumor was judged according to the proportion of positive cells in the visual field. The polymerase chain reaction (PCR) method was used to detect the expression of human-specific Alu sequence in mice tumor tissue. Results: After inoculation with tumor cells, the mice in the cell control group and the microcarrier control group did not die and did not form tumors; the mice in the cell-microcarrier complex group had palpable subcutaneous tumors in the right axillary subcutaneously on the 5th to 7th days after inoculation, and tumor formation rate is 67% (10/15), and the tumor volume can reach about 500 mm(3) 2 to 3 weeks after vaccination. The immunohistochemistry results showed that CK20, CDX-2 and carcinoembryonic antigen were all positively expressed. The PCR results showed that the expression of human-specific Alu sequence can be detected in the transplanted tumor tissue of tumor-bearing mice. Conclusion: Human primary colon cancer cells used microcarrier 6 as a carrier to form tumors in normal immunized mice, and successfully established a new model of human colon cancer transplantation tumor in normal immune mice.
