Objective To investigate the values of ultrasound measuring of the placenta thickness on evaluation of risks for alpha-thalassemia at the early pregnancy.Methods Two-dimensional ultrasound was performed to measure the thickness of placenta on 208 cases of fetuses with alpha-thalassemia and 52 cases of normal fetuses in control group.The placenta thickness was expressed as multiples of the median(MOM).Results At the early pregnancy,the group of fetuses with alpha-thalassemia had significantly higher placenta thickness compared to the fetuses without alpha-thalassemia(P＜0.001).However,there were no statistical significant difference in the placenta thickness between the other groups(P=0.100).Placenta thickness 1.18 MOM was the best critical point to predict alpha-thalassemia.The sensitivity and specificity of placenta thickness >1.18 MOM in prediction of alpha-thalassemia was 82.9%,84.7% respectively.Conclusions For those with high risks of alpha-thalassemia placenta thickness measuring is a safe,effective parameter for assessment because it could reduce unnecessary invasive procedures and improve the detecting rate of severe alpha-thalassemia.

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.

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.
