ABSTRACT
Objective:To compare the efficacy of internal fixation and external fixation in the treatment of pelvic fractures.Methods:A retrospective case control study was conducted to analyze the data of 66 patients with anterior pelvic ring fracture treated from December 2015 to December 2017 at First People's Hospital of Lianyungang, including 36 males and 30 females, with an average age of 42.7 years (range, 19 to 63 years). There were 36 patients with Tile type B fractures and 30 with Tile type C fractures. Minimally invasive percutaneous internal fixation through the anterior inferior iliac spine was performed in 33 patients (internal fixation group) and external fixator was employed in another 33 patients (external fixation group). The two groups were compared in terms of the operation time, intraoperative blood loss, fracture healing time, fracture reduction assessment with Matta criteria, Majeed score and surgical complications.Results:All patients were followed up for 9-24 months (mean, 14.5 months). The operation time was (33.7±3.6)minutes in internal fixation group , and (24.5±3.5)minutes in external fixation group ( P<0.05). Intraoperative blood loss was (25.8±3.3)ml in internal fixation group and (21.8±4.3)ml in external fixation group ( P<0.05). The fractures were healed acceptably, with the healing time of (13.8±1.6)weeks in internal fixation group and (21.7±1.9)weeks in external fixation group ( P< 0.05). According to the Matta criteria, internal fixation group showed excellent results in 17 patients, good in 14, fair in 2 and poor in 0, with the excellent and good rate of 94%; external fixation group showed excellent results in 14 patients, good in 12, fair in 6 and poor in 1 , with the excellent and good rate of 79% ( P>0.05). For Majeed function score, the results in internal fixation group were excellent in 18 patients, good in 13, fair in 2 and poor in 0, with the excellent and good of 94%; the results in external fixation group were excellent in 14 patients, good in 12, fair in 7 and poor in 0, with the excellent and good of 79% ( P>0.05). After operation, frequent urinary occurred in one patient, unilateral femoral nerve partial paralysis in one, nail cap stimulation in two and incisional redness, swelling and exudation in one in internal fixation group. In external fixation group, there were 5 patients with nail rod exudation. Conclusion:Compared with the external fixator, the internal fixation for pelvic fractures is less invasive and more reliable, can accelerate fracture healing without interfering with the patient's daily life, and can be used as the final fixation.
ABSTRACT
Objective To observe the effects of propofol on neural stem ceils in mouse developing hippocampal dentate gyrus (DG).Methods Healthy 7 d old mice from the same litters were randomly allocated into three groups:high dose propofol group,low dose propofol group and 10％ fat emulsion control group.All mice were treated with drugs on postnatal 7 d.The mice in high dose propofol group were intraperitoneally injected with 60 mg/kg propofol;the mice in low dose group were intraperitoneally injected 30 mg/kg propofol;while the mice in the control group with equivalent volume of 10％ fat emulsion.Some mice were sacrificed at 24 h after medication injection,and the others were sacrificed at postnatal 14 d.The morphology and expression levels of Ki67,Nestin,BLBP and NeuN in hippocampal DG were detected by immunohistochemical method.Results Healthy 7 d old mice from the same litters were randomly allocated into three groups:high dose propofol group,low dose propofol group and 10％ fat emulsion control group.All mice were treated with drugs on postnatal 7 d.The mice in high dose propofol group were intraperitoneally injected with 60 mg/kg propofol;the mice in low dose group were intraperitoneally injected 30 mg/kg propofol;while the mice in the control group with equivalent volume of 10％ fat emulsion.Some mice were sacrificed at 24 h after medication injection,and the others were sacrificed at postnatal 14 d.The morphology and expression levels of Ki67,Nestin,BLBP and NeuN in hippocampal DG were detected by immunohistochemical method.Conclusion High dose propofol inhibits the proliferation of neural stem cells in hippocampal DG,and impaired the prominence number of neural stem cells and causes neurons dysmaturity.

ABSTRACT
<p><b>OBJECTIVE</b>To observe catch-up growth in height within two years of birth in infants of different sexes, gestational ages, and birth weights with intrauterine growth retardation (IUGR).</p><p><b>METHODS</b>Follow-up was performed on 294 IUGR infants and 300 healthy full-term infants at 4, 6, 9, 12, 15, 18, 21 and 24 months after birth to measure the height, calculate the height increase and compare the two groups with respect to height increase.</p><p><b>RESULTS</b>The success rates of catch-up growth in height were 72.2% in male infants and 71.5% in female infants (P=0.90), and were 77.4% in preterm small-for-gestational age (SGA) infants and 68.6% in full-term SGA infants (P=0.11). Success rates of catch-up growth in height in infants with birth weights between 1500-2499 g was higher than in those with birth weights of <1500 g and ≥2500 g (P<0.01). The male infants showed significant catch-up growth at 4, 6, 18, 21 and 24 months after birth, while significant catch-up growth was found in female infants at 4, 6, 9, 12 and 21 months after birth. Of the male infants, preterm SGA infants showed significantly greater height increase than the full-term SGA infants at 6 and 9 months after birth. Of the female infants, preterm SGA infants showed significantly greater height increase than the full-term SGA infants at 4 and 18 months after birth. For both male and female infants, height increase at 4 months after birth was significantly greater in those with birth weights of <1500 g than in those with birth weights of ≥2500 g. For male infants, height increases at 4, 6, 18, 21 and 24 months after birth were significantly greater in those with birth weights of 1500-2499 g than in those with birth weights of ≥2500 g. For female infants, height increases at 4, 6, 9, 12 and 21 months after birth were significantly greater in those with birth weights of 1500-2499 g than in those with birth weights of ≥2500 g.</p><p><b>CONCLUSIONS</b>The catch-up growth in height within two years of birth in infants with IUGR occurs mainly in the first year after birth in female infants, but can be seen in the first six months and the second year after birth in male infants. Preterm SGA infants better catch-up growth than full-term SGA infants, and infants with birth weights of below 1500 g and between 1500-2499 g show better catch-up growth than those with birth weights of ≥2500 g.</p>
