This study assessed the effects of leukemia-related protein 16 (LRP16) on the regulation of pancreatic functions in mouse insulinoma (MIN6) cells. Cells with down-regulated expression of LRP16 were obtained by a shRNA interference strategy. Insulin content and glucose-stimulated insulin secretion (GSIS) were examined by radioimmunoassay. Western blotting was applied to detect protein expression. Glucose-stimulated sub-cellular localization of PDX-1 was immunocytochemically determined. Cell proliferation and apoptosis were detected by flow cytometry. Our results showed that LRP16 regulated insulin content in MIN6 cells by controlling expression of insulin and insulin transcription factors. LRP16 gene silence in MIN6 cells led to reduced cell proliferation and increased apoptosis. The observation of phosphorylation of serine-473 Akt and the localization of PDX-1 to the nucleus under glucose-stimulation exhibited that LRP16 was a component mediating Akt signaling in MIN6 cells. These results suggest that LRP16 plays a key role in maintaining pancreatic β-cell functions and may help us to understand the protective effects of estrogen on the functions of pancreatic β-cells.

Objective To evaluated the application value of two kinds of mass spectrometer(MS)and Vitek MS system in the i-dentification of routinely isolated bacteria in clinic.Methods 149 strains of common bacteria(including 14 genera and 30 species)i-solated from blood,urine,cerebral spinal fluid,secretion and sputum samples in our hospital from March 2012 to January 2013 were collected and simultaneously identified by 2 kinds of matrix-assisted laser desorption ionization-time of flight mass spectrometer (MALD-TOF-MS).The identification results were compared with those identified by the conventional biochemical identification (Vitek2 compact).The strains with the inconsistent results identified by 3 kinds of method were confirmed by 16S rDNA gene se-quencing.Results Among 149 common bacteria,the correct identification rates of genus and species by the Bruker Biotyper MS were 98% and 96% respectively and which by the Vitek MS system were 97% and 95% respectively.There were no misidentified bacterial strains by these two kinds of MS.Conclusion No statistical difference in the identification results was observed between these two kinds of MS system(P >0.05).Both exhibit excellent identification level and are suitable for the routine laboratory iden-tification of clinical microorganism.

Objective To assess the correlation between inflammation,specific immune response and coronary heart disease(CHD). Methods Thirty healthy cases passed the health examination were taken as the control group. Eighty cases who were diagnosised into CHD,affirmed by coronary angiography,were divided into three groups: acute myocardial infarction (AMI) group(26 cases),unstable angina pectoris (UP) group (24 cases),and stable angina pectoris (SP) group(30 cases). All the cases were tested on the concentrations of C-reactive protein(CRP),IgA,IgG,IgM in serum. Results The serum indices of CRP,IgG,IgA in AMI group and UP group were significantly difference than those in the control group (P0.05). Conclusion The correlation between inflammation and immune system activation are closely associated with CHD.

In order to identify rat ovarian germ cells, we expressed and purified rat RVLG protein in Escherichia coli cells and prepared a mouse anti-rat RVLG polyclonal antibody. The rat RVLG cDNA was obtained from rat testicle tissue by RT-PCR and was cloned into the vector pMD19-T. Sequence analysis proves that the cloned RVLG cDNA fragment was 60 bp longer than that released in the GenBank (NM_001077647), resulting from an alternative splicing of the RVLG pre-mRNA. The RVLG cDNA was double digested with the restriction endonucleases BamH I and EcoR I, and then was extracted from gel and inserted into the prokaryotic expression vector pGEX-4T-1. The recombinant expression plasmid pGEX-RVLG was verified for successful construction and then was transformed into Escherichia coli BL21(DE3) for induction to express the GST-RVLG fusion protein by IPTG. The GST-RVLG fusion protein was expressed in Escherichia coli BL21 (DE3) at a high level which accounts for more than 10% of the total bacterial cellular protein. The purified RVLG protein was used as an antigen to immunize KM mouse for the production of polyclonal antibody in ascetic fluid followed by celiacly injecting the mouse with S180 cells. The mouse anti-rat RVLG antibody was analyzed by ELISA, Western blotting and immunohistochemistry for its specificity and titer. The antibody could recognize RVLG protein specifically and its titer was about 1:20 000. These results confirm that the mouse anti-rat RVLG polyclonal antibody with high affinity and specificity has been prepared successfully, and lay a foundation for our ongoing research on the specific expression of RVLG in rat ovary.

Objective:To analyze the clinical characteristics of monkeypox patients.Methods:The clinical data and laboratory findings of 4 patients with monkeypox patients diagnosed at Yiwu Central Hospital in July 2023 were analyzed. Herpes fluid and skin tissue samples were collected, the viruses were isolation and cultured in African green monkey kidney cells (Vero) and identified with whole gene sequencing.Results:All four patients were male, aged 24-35 years. All patients had male-to-male behavior within 21 days before onset of the disease. Among them, one patient has AIDS and one patient has syphilis. Four patients presented with perineal skin lesions with itching, and 3 patients were found to have enlarged lymph nodes upon admission. Laboratory testing: lymphocyte abnormality (4.57×10 9/L) in 1 case; increased procalcitonin (0.25 ng/mL) in 1 case; elevated IL-10 levels ( 7.11 ng/L and 9.42 ng/L) in 2 cases; increased IL-6 (66 ng/L) and IL-4 (3.24 ng/L) in 1 case, respectively. One case had abnormal myocardial zymogram with a elevated lactate dehydrogenase level of 313 U/L. The monkeypox virus was isolated from lesion tissue and herpes fluid, and the whole gene sequencing identified it as the B. 1.3 subtype of the IIb evolutionary branch, exhibiting typical pathological effects on Vero cells. Conclusion:The clinical manifestations of the 4 monkeypox patients confirmed in Zhejiang province are mild, patients had a definitive history of male-to-male sexual behavior and the virus strains belong to the B. 1.3 lineage of the IIb evolutionary branch.

Cell mechanics is essential to cell development and function,and its dynamics evolution reflects the physiological state of cells.Here,we investigate the dynamical mechanical properties of single cells under various drug conditions,and present two mathematical approaches to quantitatively character-izing the cell physiological state.It is demonstrated that the cellular mechanical properties upon the drug action increase over time and tend to saturate,and can be mathematically characterized by a linear time-invariant dynamical model.It is shown that the transition matrices of dynamical cell systems signifi-cantly improve the classification accuracies of the cells under different drug actions.Furthermore,it is revealed that there exists a positive linear correlation between the cytoskeleton density and the cellular mechanical properties,and the physiological state of a cell in terms of its cytoskeleton density can be predicted from its mechanical properties by a linear regression model.This study builds a relationship between the cellular mechanical properties and the cellular physiological state,adding information for evaluating drug efficacy.
