ABSTRACT
Objective: To investigate the effects of antimicrobial peptide LL-37 on the tumor growth and apoptosis of the mice with colon cancer, and to elucidate the possible molecular mechanism of its anti-tumor effect. Methods: The LL-37 over-expression colon cancer HT-29 cells were constructed, and the expression levels of LL-37 mRNA and protein in the HT-29 cells were detected by qRT-PCR and Western blotting methods. A total of 30 BALB/c mice were randomly divided into control group (given the uninfected HT-29 cells)' empty vector group (given the HT-29 cells infected with empty plasmid), LL-37 over-expression group (given the HT-29 cells infected with LL-37 over-expression vector), AMPK inhibitor group [given the HT-29 cells infected with empty vector, and then injected with 2 mg • kg Dorsomorphin (Dor) in the tail vein
ABSTRACT
<p><b>OBJECTIVE</b>To determine the genetic cause of an infant with multiple congenital anomalies.</p><p><b>METHODS</b>Routine karyotype analysis and chromosome microarray analysis (CMA) were carried out for the infant and her parents.</p><p><b>RESULTS</b>CMA has detected a 9.3 Mb duplication at 9q34.11-q34.3. G-banding analysis suggested that the infant has a 46,XX,der(1)add(1)(p34.1) karyotype, while her father was 46, XY, t(1,9)(p36.3;q34.1). Fluorescence in situ hybridization (FISH) analysis confirmed that the 9q34 duplication has derived from the balanced translocation carried by the father.</p><p><b>CONCLUSION</b>A 9.3 Mb duplication was detected within the 9q34 region in an infant featuring multiple congenital anomalies. CMA and FISH have enabled detection of this duplication and facilitated genetic counseling and prevention of birth of further affected offspring.</p>
ABSTRACT
Objective Clinical effect analysis of low dose dopamine(LDD)and dobutamine (DOB)subsidiary in the treatment of 86 cases of Children serious pneumonia.Methods From July 2011 to July 2013,86 CSP patients who were diagnosed with CSP in People's Hospital of Wenzhou were selected.Patientas were randomly divided into observation group(n=43)and control group(n=43)according to the random number method.Both groups were treated with routine treatment,then observation group on the basis with LDD and DOB subsidiary,then compared efficacy of two groups at 1 week after treatment,as well as the time of symptoms and signs which had improvements,and changes of levels of Interleukin-6(IL-6),Interleukin-8(IL-8), C-reactive protein(CRP)and Tumor necrosis factor-α(TNF-α)before and after treatment. Results The efficacy in observation group was significantly better than that of control group(P<0.05 ).And time of symptoms and signs which had improvement in the observation group was significantly less than control group(P<0.05).After treatment,IL-6,IL-8,CRP and TNF-αlevels were lower than before,but the observation group had a greater degree of reducing(P<0.05).Conclusion Routine treatment combined with LDD and DOB for CSP patients,can significantly improve the therapeutic effect,and relieve the clinical symptoms.
ABSTRACT
Objective To investigate the relevant factors of neonatal ventilator-associated pneumonia(VAP),and to provide a theoretical basis of prevention and treatment.Methods Retrospective analyed the clinical data of 145 critically ill neonates,who were treated with mechanical ventilator from Jan 2006 to Dec 2009 in the Third People′s Hospital of Wenzhou City,NICU.According to whether the neonates were occurred VAP,they were divided into two groups:VAP group(52 cases) and without VAP group(93 cases).Results Fifty-two out of the 145 neonates developed VAP.The incidence of VAP was 35.86%,the main relevent factors were the gestational ages,birth weights,the duration of mechanical ventilation and the times of intubation.There was significant difference between the two groups (P<0.05).The main pathogens were opportunistic bacteria,and mostly were G-bacilli.Conclusion The incidence of VAP has a close conclusion with the gestational ages,the birth weights,the duration of mechanical ventilation and the times of intubation.Regulate the use of breathing machine,strengthen aseptic operation,and select effective antibiotic can control the occurrence and development of VAP.
