BACKGROUND:
Despite the progress in perinatal-neonatal medicine, complications of extremely preterm infants continue to constitute the major adverse outcomes in neonatal intensive care unit. Human umbilical cord Wharton’s Jellyderived mesenchymal stem cells (HUMSCs) may offer new hope for the treatment of intractable neonatal disorders. This study will explore the functional differences of HUMSCs between extremely preterm and term infants.
METHODS:
UMSCs from 5 extremely preterm infants(weeks of gestation: 22+5 w,24+4 w,25+3 w,26 w,28 w) and 2 term infants(39 w,39+2 w) were isolated, and mesenchymal markers, pluripotent genes, proliferation rate were analyzed.HUVECs were injured by treated with LPS and repaired by co-cultured with HUMSCs of different gestational ages.
RESULTS:
All HUMSCs showed fibroblast-like adherence to plastic and positively expressed surface marker of CD105,CD73 and CD90, but did not expressed CD45,CD34,CD14,CD79a and HLA-DR; HUMSCs in extremely preterm exhibited significant increase in proliferation as evidenced by CCK8, pluripotency markers OCT-4 tested by RT-PCR also showed increase. Above all, in LPS induced co-cultured inflame systerm, HUMSCs in extremely preterm were more capable to promote wound healing and tube formation in HUVEC cultures, they promoted TGFb1 expression and inhibited IL6 expression.
CONCLUSIONS
Our results suggest that HUMSCs from extremely preterm infants may be more suitable as candidates in cell therapy for the preterm infants.

PURPOSE: The role of IL28B gene variants and expression in hepatitis B virus (HBV) infections are not well understood. Here, we evaluated whether IL28B gene expression and rs12979860 variations are associated with HBV outcomes. MATERIALS AND METHODS: IL28B genetic variations (rs12979860) were genotyped by pyrosequencing of DNA samples from 137 individuals with chronic HBV infection [50 inactive carriers (IC), 34 chronic hepatitis B (CHB), 27 cirrhosis, 26 hepatocellular carcinoma (HCC)], and 19 healthy controls. IL28A/B mRNA expression in peripheral blood mononuclear cells was determined by qRT-PCR, and serum IL28B protein was measured by ELISA. RESULTS: Patients with IL28B C/C genotype had greater IL28A/B mRNA expression and higher IL28B protein levels than C/T patients. Within the various disease stages, compared to IC and healthy controls, IL28B expression was reduced in the CHB, cirrhosis, and HCC cohorts (CHB vs. IC, p=0.02; cirrhosis vs. IC, p=0.01; HCC vs. IC, p=0.001; CHB vs. controls, p<0.01; cirrhosis vs. controls, p<0.01; HCC vs. controls, p<0.01). When stratified with respect to serum HBV markers in the IC and CHB cohorts, IL28B mRNA and protein levels were higher in HBeAg-positive than negative individuals (p=0.01). Logistic regression analysis revealed that factors associated with high IL28B protein levels were C/C versus C/T genotype [p=0.016, odds ratio (OR)=0.25, 95% confidence interval (CI)=0.08-0.78], high alanine aminotransferase values (p<0.001, OR=8.02, 95% CI=2.64-24.4), and the IC stage of HBV infection (p<0.001). CONCLUSION: Our data suggest that IL28B genetic variations may play an important role in long-term development of disease in chronic HBV infections.

OBJECTIVE To provide reference for strengthening the quality of pharmaceutical care in retail chain pharmacies and the professional capabilities of licensed pharmacists, and to meet the public’s pharmaceutical care needs. METHODS A combination of questionnaire survey and informant interview was used to investigate the general information of licensed pharmacists in retail chain pharmacies in Guangdong province, the implementation of pharmaceutical care, the competence and knowledge status of the surveyed licensed pharmacists, and the factors affecting the development of pharmaceutical care. RESULTS & CONCLUSIONS A total of 444 questionnaires were sent out and 326 effective questionnaires were collected, with an effective recovery rate of 73.42%. Among 326 surveyed licensed pharmacists, a college degree or higher accounted for 40.18%, and the pharmacy major or related accounted for 79.75%. A total of 185 (56.75%) of the surveyed licensed pharmacists indicated that the retail chain pharmacies where they worked had established specified areas of pharmaceutical care; 320 (98.16%), 137 (42.02%) and 181 (55.52%) of the surveyed licensed pharmacists indicated that the retail chain pharmacies where they worked could provide services such as rational medication guidance for patients, decocting traditional Chinese medicines and establishing health records, etc. The self-assessment scores of the surveyed licensed pharmacists were significantly higher than 3 (median) for competence and knowledge level, but the self-assessment scores for medication therapy management competence and pharmaceutical care practice were relatively low. The surveyed licensed pharmacists believed that the main factors affecting the development of pharmaceutical care in retail chain pharmacies included patients’ lack of trust or cooperation (196, 60.12%), sales performance requirements (170, 52.15%), and heavy daily workload (165, 50.61%). It is recommended that relevant authorities expedite the legislative process of the Pharmacist Law, optimize the continuing education system for licensed pharmacists, and implement a star-rating evaluation system for pharmaceutical care capabilities in pharmacies, so as to encourage retail chain pharmacies and licensed pharmacists to pursue a more specialized development path. At the same time, pharmaceutical retail chain enterprises should shift their business mindset, increase investment in pharmaceutical care, enhance the professional atmosphere in the pharmacies, optimize the compensation structure for licensed pharmacists, and elevate the pharmaceutical care capabilities of both the pharmacies and licensed pharmacists to fulfill the pharmaceutical care needs of the public.

Plant fungal pathogens secrete numerous proteins into the apoplast at the plant-fungus contact sites to facilitate colonization.However,only a few secretory proteins were functionally characterized in Magnaporthe oryzae,the fungal pathogen causing rice blast disease worldwide.Asparagine-linked glycosylation 3(Alg3)is an a-l,3-mannosyltransferase functioning in the N-glycan synthesis of N-glycosylated secretory proteins.Fungal pathogenicity and cell wall integrity are impaired in Aalg3 mutants,but the secreted proteins affected in Aalg3 mutants are largely unknown.In this study,we compared the secretomes of the wild-type strain and the Aalg3 mutant and identified 51 proteins that require Alg3 for proper secretion.These proteins were predicted to be involved in metabolic processes,interspecies interactions,cell wall organization,and response to chemicals.Nine proteins were selected for further validation.We found that these proteins were localized at the apoplastic region surrounding the fungal infection hyphae.Moreover,the N-glycosylation of these proteins was significantly changed in the Aalg3 mutant,leading to the decreased protein secretion and abnormal protein localization.Furthermore,we tested the biological functions of two genes,INV1(encoding invertase 1,a secreted invertase)and AMCase(encoding acid mammalian chinitase,a secreted chitinase).The fungal virulence was significantly reduced,and the cell wall integrity was altered in the Ainv1 and Aamcase mutant strains.Moreover,the N-glycosylation was essential for the function and secretion of AMCase.Taken together,our study provides new insight into the role of N-glycosylated secretory proteins in fungal virulence and cell wall integrity.

Objective:To evaluate the efficacy and safety of lenalidomide plus dexamethasone (LD) in patients with proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID).Methods:The clinicopathological data of PGNMID patients who were treated with LD protocol from January 2010 to October 2019 were retrospectively analyzed.Results:All of 6 patients received LD treatment for≥3 months after renal biopsy in Jinling Hospital. During the follow-up period of 6 to 19 months, 3 patients achieved renal remission, and the renal remission rate was 50%(3/6). Light microscopy showed membranoproliferative glomerulonephritis and immunofluorescence showed single kappa type IgG3 was deposited in the mesangial region and the vascular loop. Before taking LD scheme, the median urinary protein were 7.76(1.27, 14.57) g/24 h, the median serum creatinine was 118.5(70.7, 289.1) μmol/L, and the median albumin was 34.5(22.4, 37.5) g/L. The concentration of serum free kappa and lambda light chain was increased in 5 patients, but the serum free light chain ratio was normal. Hypocomplementemia was detected in two cases. Six patients underwent bone marrow flow cytometry, and 2 patients had elevated monoclonal plasma cells, accounting for 0.7% and 0.5%, respectively. Immunofixation electrophoresis suggested that 1 patient had positive serum M protein for kappa type IgG3. At the last follow-up, median urine protein was 3.33(0.33, 11.23) g/24 h, median serum creatinine was 108.7(80.4, 160.9) μmol/L, and median albumin was 35.9(24.5, 45.6) g/L. The concentration of serum free light chain in 4 patients from 5 patients with elevated serum free light chain was lower than that before taking the drug. Decreased level of serum complement in two cases returned to normal after treatment. The M spike did not turn negative during the follow-up in one patient. Adverse events included anemia, neutropenia, limb numbness and upper respiratory tract infection.Conclusion:This study reports for the first time that LD protocol may be effective in treating PGNMID, but more attention should be paid to the hematological adverse events of lenalidomide.
