ABSTRACT
Objective:To study the effect of cyclin Y (CCNY) on the lesion degree of patients with liver cancer and its correlation with preoperative and postoperative liver injury.Methods:The clinical data of 60 patients with liver cancer (liver cancer group) and 69 patients with liver cirrhosis (liver cirrhosis group) in Hangzhou Hospital of Zhejiang Medical and Health Group from January 2015 to October 2017 were retrospectively analyzed. In liver cirrhosis group, Child-Pugh liver function grade A was in 33 cases (liver cirrhosis grade A group), grade B was in 21 cases (liver cirrhosis grade B group), grade C was in 15 cases (liver cirrhosis grade C group). The serum total bilirubin (TBIL), alanine aminotransferase (ALT), albumin, cholinesterase, γ-glutamyl transpeptidase (GGT) and total bile acid were detected by automatic biochemical analyzer. The serum CCNY was detected by WB method, and compared with 40 healthy subjects (healthy control group).Results:Compared with those in healthy control group, the albumin and cholinesterase in liver cirrhosis grade A, B and C groups were significantly decreased, the ALT, TBIL, GGT, total bile acid and CCNY were significantly increased, , and the changes were more obvious with the severity of liver disease, and there were statistical differences ( P<0.05). Pearson correlation analysis result showed that the CCNY was positive correlation with TBIL, ALT, total bile acid and GGT in patients with liver cancer ( r = 0.544, 0.612, 0.553 and 0.539; P<0.05), and CCNY was negative correlation with albumin and cholinesterase ( r = - 0.478 and - 0.620, P<0.05). In patients with liver cancer, before operation and 1, 2 and 7 d after operation, the CCNY was 3.01 ± 1.10, 7.24 ± 2.57, 6.29 ± 1.78 and 4.01 ± 1.52, ALT was (98.74 ± 16.79), (430.55 ± 197.62), (255.73 ± 26.77) and (121.89 ± 20.42) U/L, respectively; the CCNY and ALT 1 and 2 d after operation were significantly higher than those before operation, those 2 d after operation were significantly lower than those 1 d after operation, those 7 d after operation were significantly lower than those 2 d after operation, and there were statistical differences ( P<0.05); there were no statistical difference between 7 d after operation and before operation ( P>0.05). The expression of CCNY before operation and 1 d, 2 d, 7 d after operation was positive correlation with ALT in patients with liver cancer ( r = 0.669, 0.821, 0.663 and 0.642; P<0.01). Conclusions:The more severe the degree of liver lesions in patients with liver cancer, the higher the serum CCNY, and the higher the expression of CCNY, the more severe the degree of liver injury in patients with liver cancer due to surgery, which is positively correlated with liver injury indexes.
ABSTRACT
Objective:To investigate the relationship between rs5896 polymorphism of prothrombin gene and renal calculi in the elderly patients.Methods:Ninety elderly patients with kidney stones admitted to Hangzhou Hospital of Zhejiang Medical and Health Group from January 2014 to December 2016 were selected as observation group, and another 80 healthy people during the same period were selected as control group.The prothrombin gene rs5896 polymorphism was detected by RT-PCR, and the differences between the two groups were compared.Results:The T frequency of rs5896 allele in the observation group (64.44%) was higher than that in the control group (46.25%) (χ 2=5.687), and the TT genotype (54.44%) was higher than that in the control group (38.75%) (χ 2=4.187, P<0.05). TT genotype (77.78%) at rs5896 locus was more than single stone (38.89%), and CC genotype (16.67%) was less than single stone (37.04%) (χ 2=13.171, 4.363, all P<0.05). The serum uric acid level of TT type[(434.21±78.13)μmol/L] was higher than that of CC+ CT type[(245.73±54.20)μmol/L] ( t=13.038, P<0.05). The serum creatinine, calcium, phosphorus and potassium levels of different genotypes had not statistically significant differents (all P>0.05). The urine level of uric acid in TT-type [(415.32±56.63)μmol/L] was higher than that in CC+ CT type [(267.31±67.18)μmol/L] ( t=11.343, P<0.05), but there were no statistically significant differences in the changes of calcium, phosphorus and potassium in different genotypes of urine (all P>0.05). Conclusion:The T gene frequency of prothrombin gene rs5896 is higher and TT genotype frequency is higher in elderly patients with renal calculi.It is suggested that T gene may be a susceptible gene and that this site may lead to renal calculi through uric acid metabolic disorder, which is worthy of clinical reference.
ABSTRACT
Objective@#To establish the loop-mediated isothermal amplification (LAMP) method for detection of variola virus.@*Methods@#One set of primers were designed for recognizing 5 distinct sequences on variola virus-specific gene HA. To optimize the reaction temperature and primers screening, and the sensitivity and specificity of this method for variola virus (VARV) detection were evaluated.@*Results@#Rapid detection of variola virus by LAMP assay was completed within 60 min at 63 ℃. The sensitivity of LAMP with detection limits of 1 pg/μl was 10 times higher than that of PCR, that is, the LAMP sensitivity was 3.37×105 copies/μl, and the PCR sensitivity was 3.37×106 copies/μl. and the result of 2 kinds of other virus were negative, showing that it had a good specificity.@*Conclusions@#The method reported here demonstrates a potential and valuable means for detection of VARV. The LAMP assay is suitable for wide-area sample screening and on-site detection of variola virus in grassroots units, for on-site and primary quarantine, medical units for rapid diagnosis.
