Abstract: Objective To prepare a microparticle delivery system that regulates the release rate of extracellular vesicles (EVs), and to exert long-term enhancement of liver cell proliferation after only one intervention. Methods EVs was extracted by differential centrifugation. The structure of the EVs was observed by transmission electron microscopy and the membrane marker protein of EVs was detected by Western blotting. EVs-PLA microspheres with "core-shell" structure were prepared by emulsion-solvent evaporation method. Scanning and transmission electron microscopy were used to detect the morphology of EVs-PLA microspheres and EVs. The release test detected the release behavior of EVs in EVs-PLA microspheres. Scanning electron microscopy was used to detect the morphological changes of EVs-PLA microspheres at 8 weeks of release. EVs-PLA microspheres were co-cultured with hepatocytes, and Phalloidin/DAPI staining was used to observe the cell morphology and evaluate the cytotoxicity of the microspheres. CCK8-test was used to evaluate the cell proliferation activity. Western blot analysis was used to detect extracellular vesicles membrane marker protein expression. Results Comparing the ability of hepatocyte proliferation in the group treated with EVs-PLA microspheres and the control group, it was found that EVs-PLA microspheres did not cause cell apoptosis and mutation in cell structure, had biocompatibility and no cytotoxicity. The EVs-PLA microspheres with "core-shell" structure regulated the release behavior of EVs, which can continuously release EVs, exerting a continuous biological role in promoting hepatocyte proliferation after a single intervention. Conclusions The EVs-PLA microspheres can control-release EVs and promote hepatocyte proliferation continuously after a single intervention, providing a reference for further exploration of EVs-loaded delivery systems in promoting liver regeneration.

Objective To investigate the effects of estrogen on mismatch repiar gene expression in colonic mucosa in vivo. Methods A total of 42 healthy individuals underwent colonoscopy were enrolled in the study. Half an hour before colonoscopy examination, blood sample was taken for determining the serum estradiol (E2) level. N ormal colonic mucosal tissues determined by naked eye under colonoscopy examination were taken in the right hemi colon to detect HMLH1 and hMSH2 gene expression by semi-quantitative RT-PCR and immunohistochemistry staining. Then the correlation of serum E2 levels with hMLH1 and hMSH2 expression in colonic mucosa was analyzed. Results A bimodal curve was presented for the correlation between serum E2 level in healthy individuals and hMLH1 expression in colonic mucosa. A strong positive correlation of E2 level with hMLH1 expression in normal colonic mucosa was observed when serum E2 level was more than 45 pg/ml (For mRNA, P=0. 003, r=0. 701; for immunohistochemistry positivity index, P=0. 000, r=0. 874).However there was no correlation between E2 level and hMSH2 expression. Conclusion High serum E2 level might increase the hMLH1 gene expression in colonic mucosa in vivo.

Objective:To investigate the clinicopathological characteristics of renal light and heavy chain amyloidosis (AHL).Methods:Ten patients with renal AHL diagnosed by renal biopsy in Peking University First Hospital and Institute of Nephrology of Peking University from January 2015 to June 2020 were enrolled. Clinicopathological data of these patients was collected and reviewed.Results:AHL typically affected older patients, with a male/female ratio of 7:3. The clinical manifestations were mainly edema and heavy proteinuria. At the same time, 7/10 of patients presented with nephrotic syndrome, 7/10 presented with microscopic hematuria, and 3/10 presented with renal insufficiency. Laboratory examinations showed monoclonal immunoglobulin in blood and urine in all patients, and IgGλ was the most common one (5/10). Decreased serum complement could be seen in some patients. The ratio of serum free κ light chain and free λ light chain was abnormal in all patients who underwent serum free light chain test. None of the 10 patients met the diagnostic criteria of multiple myeloma. Except for one of the 10 patients who was diagnosed as Waldenstrom's macroglobulinemia, the rest were diagnosed as monoclonal gammopathy of renal significance (MGRS). Bone marrow of 2/6 of patients were positive for amyloid. Cardiac involvement was confirmed in only one patient. Renal biopsy demonstrated amorphous eosinophilic material, which was Congo red positive, was deposited in glomerular mesangial area (10/10), capillary vessels (8/10), renal interstitium (9/10), peritubular capillary walls (9/10) and arterioles (8/10). This material showed apple green birefringence under polarized light. Immunofluorescence showed that single heavy chain and single light chain were positive at the same time, which was consistent with the results of mass spectrometry analysis. Ultrastructural evaluation revealed randomly oriented, non-branching fibrils with a diameter of 8-12 nm.Conclusions:Main clinical manifestations of AHL amyloidosis are edema and massive proteinuria, along with a high incidence of hematuria, a low portion of heart involvement and high frequency of whole molecule of monoclonal immunoglobulin (IgGλ dominant) by serum immunofixation electrophoresis. Renal pathology shows the commonly involved kidney compartments of amyloid deposits are glomerular capillary walls and peritubular capillary walls in patients with AHL amyloidosis.
