Objective To investigate the MR features of uterine leiomyomas and evaluate its diagnostic value. Methods Twenty six patients with probable uterine leiomyomas underwent preoperative ultrasound, T 1 weighted spin echo and T 2 weighted fast spin echo MR examinations. Among them, 11 cases were performed with dynamic contrast enhancement. Comparative analysis between MRI findings and pathologic results was done. Results MRI diagnosis in all cases was consistent with the results given by surgery and pathology, except 2 being pathologically proven as endometrial polyp or inflammatory pseudoplasma. The diagnostic accuracy of MRI was 92%, while the accuracy of ultrasound was 85%. The difference between the number of lesions detected by two modalities had statistical significance (89% for MRI vs 69% for ultrasound, ? 2=17.86, P

Objective To study the effect of clopidogrel on different CYP2C19 genotypes and platelet reactivity in acute cerebral infarction patients with antiplatelet aggregation.Methods Four hundred and seventy-four cases of cerebral infarction patients in Beijing Tiantan Hospital Affiliated to Capital Medical University from April 2015 to April 2016 were collected.CYP2C19 genotype was determined,and the genotype was divided into the wild type group,the heterozygous type group and the mutant homozygous group.Platelet aggregation inhibition rate(ADP%) and platelet reactivity index induced by ADP were detected.Patients were divided into clopidogrel resistance group(group CR) and non resistant group according to whether ADP% was less than 30.SPSS 16.0 statistical software was used for statistical analysis,the comparison between groups using independent samples t test,chi square test and multivariate analysis using Logistic regression analysis,when P<0.05 difference was statistically significant.Results Among the 474 patients,204 cases(43.04%) were divided into wild-type group,and 204(43.04%) and 66(13.92%) were divided into the mutant heterozygous group and mutant homozygous group.In Chi square test analysis,clopidogrel resistance group and non resistance group CYP2C19 genotype distribution was significantly different(χ2=6.658,P=0.036).CR group angle(α) values((68.87±5.47)°) and MA((66.77±6.25) mm) were higher than that of CS group ((66.55±6.05)° and (63.30±5.66) mm,t=2.199,3.387,P=0.029,0.001).The multivariate logistic regression analysis showed that OR of angle level was 1.028,95%CI was 0.929-1.137 (P=0.595);OR of Ma level was 1.561,95%CI was 0.785-0.970 (P=0.012).Conclusion The effect of clopidogrel on platelet aggregation in patients with acute cerebral infarction is decreased by CYP2C19 gene mutation.CYP2C19 mutant allele is a risk factor for clopidogrel resistance.Angle (α) value and MA value are the risk factors for the diagnosis of CR in the patients with acute cerebral infarction,and the risk of clopidogrel resistance increased when the patients′ Angle (α) value and the value of MA increased.MA value as a predictor of CR and the screening tool has a certain value.

Objective In order to understand whether recombinant human growth hormone(r-hGH) can improve the idiopathic short stature(ISS) boys' final adult height(FAH).Methods We measured 16 cases diagnosed as ISS boys FAH, divided into 2 groups, of which 9 cases were not given r-hGH treatment, treatment group ,7 patients received r-hGH treatment, a dose of 0.1 ～ 0.13 U· kg-1·d-1, before going to sleep subcutaneous injection, duration of treatment was 6 ～ 20 months ( 11.9 ± 5.2 months).Results The treatment group compared with the average FAH FAH observation group had significantly improved the average(t =2.219,P<0.05).Conclusion r-hGH can improve the ISS boys FAH, but early treatment, the longer the course the more obvious effects.

Objective:To investigate the protective effect of Epigallocatechin-3-gallate (EGCG) on triptolide (TP)-induced immunological liver injuries, and explore the relevant mechanisms of action. Methods: A total of 40 female C57BL/6 mice were randomly divided into four groups:control group,EGCG group,TP group and TP+EGCG group. The ALT levels in serum was examined by Reitman Frankel method. The activity of hepatic MDA,SOD and GSH was examined by spectrophotometry. HE staining was used to observed the changes of the hepatic histopathology. The hepatic IL-17,IL-6 levels was examined by ELISA and the expression of hepatic TLR4 protein was examined by Western blot. Results:The results showed that serum alanine aminotransaminase ( ALT) levels of TP group were obviously elevated (P<0. 005,vs normal control group) and serum ALT levels were obviously reduced in EGCG treatment group(P<0. 005,vs normal TP group). There were no significantly differences between EGCG group and control group (P>0. 05). Meanwhile,EGCG could ameliorate hepatic pathological damage. Furthermore,in TP group,the activity of malondialdehyde ( MDA) ,the expression of Toll-like receptor 4 (TLR4) protein and the contentration of hepatic interleukin (IL)-17,IL-6 were higher than normal control group ( P<0. 005 ) . On the contrary, the activity of superoxide dismutase ( SOD ) and restored glutathione ( GSH ) were significantly lower than normal control group ( SOD, P<0. 05;GSH, P<0. 005 ) . In EGCG treatment group, the expression of TLR4 protein and the concentration of MDA,hepatic IL-17 and IL-6 were lower than TP group ( TLR4,P<0. 05;MDA,P<0. 005;IL-17,P<0. 005;IL-6,P<0. 005). On the contrary,SOD and GSH were significantly higher than TP group (SOD,P<0. 05;GSH,P<0. 005). Conclusion:This study suggests that EGCG possesses hepatoprotective effect against TP-induced immunological liver injury through its anti-inflammatory and anti-oxidant actions.

Objective To analyze the prevalence of human papilloma virus(HPV) and the relationship between HPV and vaginal environment in puerperium women.Methods One thousand and twenty-nine cases puerperium women were detected for HPV subtype by using nucleic acid flow-through hybridization.Patients with HPV positive had been considered as observe group and the rest as control.The prenatal infection of HPV of HPV-DNA positive and negative postpartum puerperium women, and the vaginal cleanliness of prenatal and postpartum were analyzed.Results In 1 029 cases puerperium women, the total HPV-DNA positive rate was 10.30％(106/1029) ,and high risk infection rate was 95.65％ (110/115).The rate of HPV positive before pregnant in HPV positive group (46.51％, 40/86) was higher than that in HPV negative group (9.09％, 10/110).There was significant difference of vaginal environment in the two groups (x2 =36.567, P＜0.05).In HPV-DNA positive and negative women during the puerperium vaginal cleaning degree of Ⅰ , Ⅱ ratio prenatal respectively were 56.98％ (49/86) and 76.36％ (84/110), and the difference was significant (x2 =8.317, P ＜0.05).Postpartum to 45.35％ (39/86) and 60.00 (66/110), and the difference was significant (x2 =3.941, P＜0.05).Conclusion The HPV infection of pregnant women are easy to getagain.There is relevance between HPV infection and vaginal environment.
