ABSTRACT
Objective To investigate the curative effect of ultra early enteral nutrition (EN) supplemented with probiotics in patients with severe acute pancreatitis (SAP).Methods Seventy-five SAP cases admitted in Second People's Hospital of Nantong from December 2014 to June 2018 were enrolled and assigned into 24 h group (who received EN & probiotics at 24 h,n =25),72 h group (who received EN & probiotics at 72 h,n =25) and the control group (who received EN & probiotics on day 7,n =25).After admission,the levels of PCT,hs-CRP and endotoxin on day 1,4 and 8 were detected.APACHE Ⅱ score on day 3 after admission,complication rate,infection rate,hospitalization duration and mortality were recorded.Results On day 1 after admission,serum PCT,hs-CRP and endotoxin concentrations among three groups were of no significant differences.On day 4 after admission,the serum concentrations of PCT and edotoxin in 24 h group were significantly lower than those in 72 h group and the control group [(3.12 ± 1.45) μg/L vs (5.26±1.52),(6.07 ± l.59) μg/L;(0.24 ± 0.02) EU/ml vs (0.35 ±0.03),(0.46±0.04) EU/ml].The serum hs-CRP in 24 h group was significantly lower than that of the control group [(20.71 ±4.89) μg/L vs (28.37 ± 4.64) μg/L],and the difference was statistically significant (P ＜ O.05).The serum concentrations of hs-CRP in 24 h group and 72 h group was of no significant difference.On day 7 after admission,the serum concentrations of PCT,hs-CRP and endotoxin in 24 h group were significantly lower than those in 72 h group and the control group (P ＜0.05);the serum concentrations of PCT,hs-CRP and endotoxin in 72 h group were significantly lower than those of the control group,and all the differences were statistically significant (all P ＜ 0.05).The score of APACHE Ⅱ (day 3 after admission) [(15.1 ± 1.8)],complication rate (52％),infection rate (8％),length of stay [(19.7 ± 5.3) d] in 24 h group were all significantly lower than those of 72h group [(17.0 ± 2.0),72％,32％,(25.4 ± 6.8) d] and control group [(18.3 ±2.6),84％,44％,(38.7 ± 12.6) d],and all the differences were statistically significant (all P ＜0.05).Conclusions Ultra EN supplemented with probiotics in treating the patients with SAP could significantly reduce the level of serum PCT,hs-CRP and endotoxin,decrease complication rate and mortality,and shorten the time of hospitalization.
ABSTRACT
Traditional immunological strategy which largely based on antigen-antibody techniques such as CA153,cytokeratin CK8/18/19,is still the main diagnostic biomarkers for breast cancer.Molecular biology markers such as BRCA1/2 and HER2 are becoming popular and hot.This article summarizes recent progress of breast cancer diagnosis based on nucleic acid related strategies such as circulating DNA,miRNAs,aptamers and circulating tumor cells.
ABSTRACT
Objective To investigate the relationship between single nucleotide polymorphism in estrogen metabolizing genes CYP17、CYP19 and breast cancer susceptibility.Methods A case-control study was performed.PCR-base restriction fragment length polymorphism(PCR-RFLP)and short tandem repeat polymorphism(STRP)assay were used to detect the single nucleotide polymorphism of CYP17、CYP19 in 213 breast cancer cases and 430 matched controls.Resuits CYP17 A2/A2 genotype was found in 6.7%of breast cancer cases,which was significantly higher(P＜0.05)than that in controls(2.4%);the frequency of A2 allele of CYP17 was 16.2%in breast cancer cases,which was significantly higher(P＜0.05)than that in controls(10.6%).There Was alSO significant difference in the frequency of(TTTA)10allele of CYP19 which was 12.4%in breast cancer cases and 8.2%in controls(P=0.02).Conclusions The allele of CYP17 A2 and CYP19(TTTA)10 and CYP17 A2/A2 genotype were positively associated with the susceptibility of breast cancer.
