Objective To study the application value of serum umbilical cord blood bilirubin and hemolysis three test in the prediction of neonatal hyperbilirubinemia.Methods 1 200 cases of healthy newborn were selected,whose mothers were type O blood and fathers were not type O blood.According to the situation of maternal and infant blood type,they were divided into the same maternal and child blood type group with 539 cases and different blood type group with 661 cases;According to the umbilical cord blood bilirubin concentration range was divided into five groups,and analyzed umbilical cord blood bilirubin and hemolysis three test in the prediction of neonatal hyperbilirubinemia.Results (1) The concentrations of umbilical cord blood bilirubin,the incidence of ABO-HDN,the incidence of hyperbilirubinemia in the maternal-fetal blood(O-A/B) group were (38.1 ± 10.3) μmol/L,47.35％,26.02％,respectively,which were all significantly higher than (33.4 ± 7.9)μmol/L,15.21％,14.66％ in the maternal blood type (O-O) group (t =5.8,x2 =120.7,x2 =20.1,all P =0.000) ; (2) When the concentrations of umbilical cord blood bilirubin was higher,the incidence of hyperbilirubinemia was higher,but the sensitivity and the specificity both were bad; (3) According to the result of hemolysis three to predict the neonatal hyperbilirubinemia,when the concentrations of umbilical cord blood bilirubin was less than 21μmol/L or more than 55μmol/L,the positive predictive value and the specificity both were 100.00％,and the sensitivity was not low(75.00％ and 86.96％).Conclusion Detection of umbilical cord blood bilirubin and hemolysis three test in the maternal-fetal blood group incompatibility could predict early hyperbilirubinemia of newborn,which had certain clinically practical value.

AlM:To investigate the opportunity of the concomitant strabismus operation and the function in the treatment of strabismic amblyopia through analyzing the changes of binocular summation of pattern visual evoked potential ( P-VEP ) before and after the surgery of concomitant strabismus.
METHODS: ln this retrospective study we investigated 67 cases admitted in our hospital. All patients were less than 18a and the postoperation squint angle was less than ± 10△. Patients were divided into three groups according to the strabismus type, age, and amblyopia degree. P-VEP binocular summation response was recorded in all cases, to observe the changes of the binocular summation response of P-VEP before strabismus surgery and 1mo, 3mo after surgery. The P-VEP response of binocular /monocular ( B/M ) ratio was taken as an evaluation index.
RESULTS: B/M value of three groups all improved obviously 1mo after surgery, which the difference showed statistical significant (P<0. 01). 1) After 3mo surgery, B/M value in esotropia group was higher than that in exotropia group (P<0. 05). 2) After 3mo surgery, B/M value in≤6a group was higher than that in >12a group (P<0. 05). 3) After 1mo surgery, B/M value in severe amblyopia group was higher than that in mild group (P<0. 05). After 3mo surgery, B/M value in severe amblyopia group was higher than that in mild group significantly (P<0. 01).
CONCLUSlON: Concomitant strabismus surgery is suggested to be performed before 6 years old when the patients are difficult to improve the vision after amblyopia treatment, especially with the severe amblyopia and esotropia (accommodative esotropia must be excluded). The early operation is better to amblyopia treatment and binocular vision recovery.

Objective To evaluate the growth inhibition and apoptosis of human monocytic leukemia THP-1 cell line by using 5,8-dimethyl-2-β-hydroxyisovalerylshikonin (SK36) and explore its preliminary mechanism. Methods CCK colorimetric assay and cell counting was used to examine the growth inhibition of shikonin on THP-1 cells. The apoptosis of THP-1 cells was detected by Annexin V/PI double labeling. The activation of Caspase-3 apoptosis pathway was determined by FCM. The apoptosis and the necrosis of THP-1 cells were detected by the laser scanning confocal microscopy. Results When the THP-1 cells were treated with SK36 at 1.02 μg/ml for 24 h and 48 h, the growth inhibition was dose-dependent. The cell apoptotic rate of THP-1 cells treated with 1.02 μg/ml evaluated by FCM with Annexin V/PI double labeling staining were (40.61 ±2.13) % and (67.40±9.15) % at 24 h and 48 h after treatment, respectively, which were significantly higher than that of the control group [(16.97±0.61) %] ([ = 18.444, t = 9.528, P <0.01). SK36 could induce THP-1 cells apoptosis involving the activation of Caspase-3 (F= 323.61, P<0.01). Conclusion SK36 can induce human THP-1 cells to undergo apoptosis, and its primary mechanism was to activate the Caspase-3.
