Regulation of stem cells by transforming growth factor Β3/polylactic acid-glycolic acid microspheres / 中国组织工程研究

BACKGROUND: Transforming growth factor Β3/polylactic acid-glycolic acid (TGF-Β3/PLGA) sustained-release microspheres can maintain the effective drug concentration at the site of action and provide the feasibility for efficient utilization of growth factors. OBJECTIVE: To optimize the manufacturing process of TGF-Β3/PLGA sustained-release microspheres, and investigate their effects on the proliferation and migration of rabbit adipose-derived mesenchymal stem cells (ADSCs). METHODS: TGF-Β3/PLGA sustained-release microspheres were prepared by emulsification-solvent evaporation method. The morphology, particle size, drug spatial distribution, encapsulation efficiency, drug loading, and sustained release properties of the microspheres were characterized. The TGF-Β3/PLGA sustained-release microspheres were dissolved in phosphate buffered saline. The concentration of TGF-Β3 in the supernatant was detected at the corresponding time points. The microsphere morphology was observed by scanning electron microscopy at the corresponding time point. Adipose-derived mesenchymal stem cells were divided into six groups and then cultured with single culture medium (negative control) or culture medium containing TGF-Β3 or blank PLGA, or culture medium containing 10,100,1 000 g/L TGF-Β3/PLGA microspheres. Cell proliferation was detected by CCK-8 assay at the corresponding time point. Cells in each group were cultured for 24 hours with corresponding medium in a non-contact manner. The number of migratory cells was counted. RESULTS AND CONCLUSION: (1) TGF-Β3/PLGA sustained-release microspheres were spherical with smooth surface, no adhesion, and evenly distributed particle size. The microspheres had a diameter of 2-50 µm, and the protein drugs in the microspheres were evenly distributed, with high encapsulation efficacy and encapsulation dose. (2) The TGF-Β3/PLGA sustained-release microspheres had good degradation properties and were completely degraded after 6 months in vitro. At the same time, these microspheres had good sustained-release performance and released TGF-Β3 slowly for 45 days in vitro. (3) Blank microspheres and the sustained-release microspheres containing TGF-Β3 had no effect on the proliferation of adipose-derived mesenchymal stem cells. (4) Blank microspheres had no effect on the migration of adipose-derived mesenchymal stem cells, and the transforming growth factor 3 and the sustained-release microspheres containing TGF-Β3 promoted the migration of adipose-derived mesenchymal stem cells. There was no significant difference in the migration promotion between different concentrations of TGF-Β3. (5) These findings suggest that the TGF-Β3/PLGA sustained-release microspheres can promote the migration of adipose-derived mesenchymal stem cells without affecting their proliferation.

Expression of HOPX in cervical cancer tissues and blood serum and its correlation to CEAand CA125 / 中国肿瘤生物治疗杂志

@# Objective: To investigate the expression of HOPX gene in cervical cancer tissues and blood serum as well as its effect on cervical cancer HeLa cells, and to analyze its correlation to tumor maker CEAand CA125. Methods: 50 pairs of cervical cancer tissues and para-cancerous tissues as well as the peripheral blood samples from patients with cervical cancer, who were treated at Tianjin Binhai People’s Hospital and Tianjin Wuqing People’s Hospital from June 2015 to December 2017, were collected for this study; in addition, 50 samples of blood serum from healthy people were used as control. Real-time quantitative PCR (qRT-PCR) and immumohistochemical staining (IHC) were used to detect mRNA and protein expressions of HOPX in tissue and serum samples, NCBI-GEO data base and TCGA data base were used to collect the information on HOPX gene and patients’prognosis, and the correlation between HOPX expression and patients’prognosis was analyzed. Vectors over-expressing HOPX or control vectors were transfected into HeLa cells; MTT assay and colony formation assay were used to examine the proliferation ability of HeLa cells, Tranwell assay was used to detect the migration and invasion of HeLa cells, and Western blotting was used to detect the expression of EMT-related proteins. Results: Both sample examination and data base information showed that the expression level of HOPX was down-regulated in tissue and serum samples of cervical cancer patients and was positively related with the survival of patients (r=0.736， P<0.05); while it’s expression was negatively related to the level of CEAand CA125 in cervical cancer tissues and serum (r=-0.678, P<0.05). HOPX over-expression inhibited cell proliferation, migration and invasion, promoted the expression of E-cadherin but inhibited the expression of Vimentin and ICAM1 (all P<0.05 or P<0.001). Conclusion: HOPX is low expressed in cervical cancer tissues and blood samples, and negatively correlated with CEA and CA125, but positively correlated with the survival of patients. Thus, combination of HOPX and CEA/CA125 may improve the early diagnosis rate of cervical cancer and provide a new strategy for precision treatment of cervical cancer in future.

Distribution and antimicrobial resistance profile of the clinical bacterial strains isolated from Beijing Children's Hospital from 2009 to 2015 / 中国感染与化疗杂志

Objective To investigate the distribution and antimicrobial resistance profile of the common pathogens isolated during the period from 2009 to 2015.Methods All the bacterial strains isolated from pediatric inpatients in Beijing Children's Hospital during the period from 2009 to 2015 were analyzed. Antimicrobial susceptibility was determined by disk diffusion method and Phoenix 100 Automated Microbiology System. Results were analyzed according to the guidelines of CLSI (2014) using WHONET 5.6 software.Results The total strains were 26630. The most common gram-positive isolates were Streptococcus pneumoniae,Staphylococcusaureusand coagulase-negative Staphylococcus (CNS), while the most frequently isolated gram-negative microorganisms were Klebsiella spp.,Pseudomonas aeruginosa and Escherichia coli. The prevalence of S. pneumoniae was up to 25.7 % (4101/15973) in all respiratory tract specimens. About 50.2 % of the S. pneumoniae isolates were not susceptible to penicillin. The prevalence of methicillin-resistant strains was 20.6 % in S. aureus (MRSA) and 87.8 % in coagulase negative Staphylococcus (MRCNS) on average. The prevalence of MRSA increased from 11.1 % in 2009 to 29.8 % in 2015. No S. pneumoniae or staphylococcal strains were found resistant to vancomycin or linezolid. The Enterococcus strains were still highly susceptible to vancomycin and linezolid. Overall 0.3 % of the Enterococcus faecium isolates were resistant to vancomycin. The extended-spectrum beta-lactamases (ESBLs) producing strains accounted for 71.4 % -78.1 % of E. coli and 65.1 % - 76.9 % of K. pneumoniae isolates. The carbapenem-resistant E. coli and K. pneumoniae were reported for the first time in 2010, but in 2014, the strains resistant to carbapenems had increased to more than 7 % in E. coli, and higher than 20 % in K. pneumoniae. In 2015, up to 27.7 % and 25.7 % of P. aeruginosa isolates were resistant to imipenem and meropenem, respectively, and 59.9 % of the A. baumannii isolates were resistant to imipenem and meropenem. Beta-lactamase was positive in 46.3 % of the H. influenzae isolates. Conclusions MRSA and the carbapenem-resistant strains of E. coli,K. pneumoniae and A. baumannii are still on the rise in pediatric inpatients, which poses a serious threat to clinical practice and implies the importance of strengthening infection control.

Distribution and antibiotic resistance profile of 350 strains of Haemophilus influenzae isolated from children / 中国感染与化疗杂志

Objective To analyze the distribution and antibiotic resistance profile of Haemophilus influenzae strains isolated from children for better antibiotic use.Methods The clinical and laboratory data concerning 350 strains ofH.influenzae were collected and analyzed retrospectively from 2014 to 2015 in our hospital,including pathogen source,production of beta lactamases and antimicrobial susceptibility.Antimicrobial susceptibility testing was carried out by using disk diffusion method.The results were interpreted according to the breakpoints of the Clinical and Laboratory Standards Association (CLSI) in 2014,and analyzed using WHONET 5.6 software.Results H.influenzae infection was more common in infants and young children.The prevalence of beta lactamase was 53.1％ in H.influenzae isolates.The H.influenzae isolates showed the highest resistance rate to trimethoprimsulfamethoxazole (76.9％),but relatively high susceptible rate to ciprofloxacin (99.1％),ceftizoxime (98.9％),chloramphenicol (95.4％),tetracycline (88.3％),amoxicillin-clavulanic acid (87.7％),cefuroxime (74.9％),azithromycin (65.4％),cefaclor (56.6％) and ampicillin (46.0％).All these H.influenzae strains were susceptible to ceftriaxone and meropenem.Conclusions Beta-lactamases are highly prevalent in the H.influenzae strains isolated from children,which is the main mechanism underlying ampicillin resistance in H.influenzae.Ampicillin is therefore not appropriate for first-line treatment ofH.influenzae infections.The H.influenzae strains are highly resistant to trimethoprim-sulfamethoxazole.In addition to beta-lactams,ciprofloxacin is the most active agent against H.influenzae strains,followed by chloramphenicol.

Objective To investigate the effect of rosiglitazone on the proliferation and apoptosis of colon cancer cells and the changes in the AKT/GSK3β signaling pathway. Methods Different concentrations of rosiglitazone ( 20. 0μmol/L, 40. 0 μmol/L, 80. 0 μmol/L) were used to treat colon cancer HT29 cells and HCT116 cells. Cell proliferation was detected by MTT assay. Annexin V FITC/PI cell death detection kit was used to test the cell apoptosis rate. The expression of apoptotic protein Bcl-2, Bax and Akt, GSK3β were detected by Western blot. Results Different concentrations of rosiglitazone had different effect on the proliferation of colon cancer cells compared with the blank control group, and showed a dose dependence (P< 0. 01). With the increase of rosiglitazone dose, the apoptosis-inducing effect @was increased dose-dependently (P< 0. 01). When the cells were treated with rosiglitazone for 48 h, the expressions of Bcl-2/Bax, p-GSK3β, and p-Akt were significantly decreased compared with the blank control group (P< 0. 01), but the expression level of Akt and GSK3β was not significantly different compared with the blank control group ( P > 0. 05 ) . Conclusions Rosiglitazone significantly induces apoptosis and inhibits the proliferation of HT29 cells. It may be via inhibiting Akt/GSK3β signaling pathway and change the ratio of Bcl-2/Bax.

The immunogenicity and anti-tumor effects of a lung cancer DNA vaccine harboring a MUC-1 and GM-CSF fusion gene

ABSTRACT DNA vaccines have been shown to be an effective approach to induce antigen-specific cellular and humoral immunity. However, the inability of DNA vaccines to elicit strong immune responses in clinical trials limits the application of DNA vaccines. Here, we developed a new DNA vaccine based on MUC1, which has been suggested as a potential target for lung cancer therapy, and we enhanced the potency of the DNA vaccine by including granulocyte-macrophage colony-stimulating factor (GM-CSF) as an adjuvant. A series of DNA plasmids encoding MUC1, human GM-CSF and their conjugates were constructed and injected into female mice intramuscularly (i.m.). This action was followed by an electric pulse. The humoral and cellular immune responses after immunization were examined by ELISA and ELISPOT, respectively. To evaluate the therapeutic efficacy of the plasmids, a mouse model with a MUC1-expressing tumor was designed. Mice vaccinated with the MUC1-GM-CSF plasmid generated the strongest MUC1-specific humoral and cellular immune responses. Furthermore, these vaccinations inhibited the growth of MUC1-expressing tumors and prolonged mouse survival. These observations emphasize the potential of GM-CSF as an adjuvant for DNA vaccines and of vaccines based on MUC1 and GM-CSF as a promising treatment for lung cancer.

Synthesis and evaluation of artificial antigens for astragaloside IV

The objective of this study was to produce artificial antigens for astragaloside IV that could be used to prepare antibodies against astragaloside IV screened in Radix astragali (Astragalus membranaceus (Fisch) Bunge, Fabaceae) and its preparations, using an indirect ELISA. Astragaloside IV was coupled to carrier proteins, bovine serum albumin and ovalbumin using the sodium periodate method and was then evaluated using SDS-PAGE, MALDI-TOF MS and animal immunizations. The coupling ratio of astragaloside IV to bovine serum albumin ratio was determined to be thirteen, and the indirect ELISA demonstrated that three groups of mice immunized with astragaloside IV-bovine serum albumin produced anti-astragaloside IV- bovine serum albumin-specific antibody, with a minimum serum titer of 1:9600. A method for synthesizing highly immunogenic astragaloside IV artificial antigens was successfully developed thus indicating its feasibility in the establishment of a fast immunoassay for astragaloside IV content determination in Radix astragali and its products.
