BACKGROUND: Threatened abortion is a high risk pathological change during gestation. Fetus usually could be protected after the application of all kinds of medical interventions; however, whether the healthy development of the newborn could be assured simultaneously when a new life is protected?Especially the long-term impact on the normal development of the intelligence is an important issue deserving investigation.OBJECTIVE: To investigate the differences of intelligence level between protected fetus after threatened abortion and normal mature fetus, and the influencing factors.DESIGN: A case-controlled observational comparative study introducing children as the subjects.SETTINGS: Psychological department of a normal university; Department of gynecology and pediatrics of a district women and children' s health care hospital.PARTICIPANTS: Totally 170 children(mature and natural delivery after protection) of 5 to 7 years old, whose mothers experienced threatened abortions during gestation, and 182 children born in the same period(normal mature and natural delivery) of 5 to 7 years old, whose mothers did not have threatened abortion history were selected as the subjects. No other factors would affect the intellectual development in the subjects of both groups.INTERVENTIONS: The Chinese Version of Wechsler young children scale of intelligence(C-WYCSI) for children below 6 years old or Wechsler intelligence scale for children-Chinese revision( WISC-CR ) for children no younger than 6 years old were introduced in the individual test performed by trained psychological junior students for every testee.children in both groups [intelligence quotient(IQ) gained in the intelligence of mother on the intellectual development of the children in both groups.was found in the testees, the IQ of all tested children was within the normal dren was sinificantly lower in the threatened abortion group than in the normal were significant interactions between threatened abortion and gender, body mass at birth and the pregnant age of mother, etc.: if the mother experienced threatened abortion, the newborn would be even more easily to suffer from relative low body mass at birth(low body mass fetus accounted for 28% of threatened abortion group, which accounted for about 66% of the total low body mass at birth fetuses in our study); the male newborn would be even more easily to have relative low intellectual development(the difference of IQ between the male children of two groups was significant) (F = 2. 809, P < 0.05). Especially, the negative impact on children' s intellectual development would be even greater if the pregnant woman were older than 35 years old and had threatened abortion experience(the average IQ of 32 tested children was 86).CONCLUSION: Threatened abortion might be a potential innate factor that would affect the intellectual development of the children. For those high-risk individual cases with this kind of experience, early intervention should be prepared as early as possible to create a favorable substantial and culture environment for avoiding the actual occurrence of delayed intelligence.

To establish a fast sensitive, reproducible LC-MS/MS method to study pharmacokinetic properties of THC, and compare relative bioavailability of THC and its solid dispersion in mice. 200 mice were divided randomly into two groups, and administered orally with THC and THC-solid dispersion after fasting (calculate on THC:400 mg x kg(-1)), used HPLC-MS/MS method to determine the THC concentration of each period at the following times: baseline ( predose ), 15, 30, 45 min, 1, 1.5, 2, 3, 4, 6, 24 h after dosing. Calculating the pharmacokinetic parameters according to the C-t curv, and then use the Phoenix WinNonlin software for data analysis. The calibration curves were linear over the range 9.06-972 microg x L(-1) for THC (R2 = 0.999). The limit of detection (LOD) was 0.7 microg x L(-1), respectively. The average extraction recoveries for THC was above 75%, The methodology recoveries were between 79% and 108%. The intra-day and inter-day RSD were less than 13%, the stability test showed that the plasma samples was stable under different conditions (RSD < 15%). The precision, accuracy, recovery and applicability were found to be adequate for pharmacokinetic studies. Pharmacokinetic parameters of THC and THC-solid dispersion orally to mice shows as fllows: T(max), were 60 and 15 min, AUC(0-t) were 44 500.43 and 57 497.81 mg x L(-1) x min, AUC(0-infinity) were 51 226.00 and 68 031.48 mg x L(-1) x min, MRT(0-infinity) were 596.915 6, 661.747 7 min, CL(z)/F were 0.007 809 and 0.005 88 L x min(-1) x kg(-1). Compared with THC, the MRT and t1/2 of the THC-solid dispersion were all slightly extended, the t(max) was significantly reduced, AUC(0-24 h), AUC(0-infinity) and C(max) were all significantly higher, the relative bioavailability of THC-solid dispersion is 1.34 times of THC. The results of the experiment shows that the precision, accuracy, recovery and applicability were found to be adequate for the pharmacokinetic studies. After oral administration to mice, the relative bioavailability of THC-solid dispersion show significant improvement compared to THC.

BACKGROUND:Transoral ventral release and posterior fusion have predominated in the treatment of irreducible atlantoaxial dislocation, but there is no consistent conclusion on the clinical efficacy.
OBJECTIVE:To explore the clinical outcomes of transoral ventral release and posterior fusion and screw/rod implantation in the treatment of irreducible atlantoaxial dislocation.
METHODS:A total of 32 patients with irreducible atlantoaxial dislocation undergoing thetransoral ventral release and posterior fusion were selected. After treatment, they received cervical anteroposterior and lateral digital DR and cervical MRI examinations to understand the conditions of nerve compression and bone fusion. The recovery of nerve function was evaluated using Japanese Orthopaedic Association before treatment, 6 months after treatment and during final fol ow-up.
RESULTS AND CONCLUSION:Post-treatment, 29 patients were fol owed-up for an average period of 12 months. (1) Al the patients obtained perfect atlantoaxial joint reduction and bone fusion. This achieved reduction and reconstruction of spinal column stability. (2) Spinal compression was obviously lessened after treatment in al patients, and nerve functions were improved to different degrees. Significant differences in Japanese Orthopaedic Association score were detected between 6 months post-treatment, final fol ow-up and pre-treatment (P<0.05). (3) There were no serious intraoperative complications such as spinal cord or vertebral artery injuries. Postoperative complications such as infection or burst were also not found. (4) Imaging evaluation revealed that transoral ventral release and posterior fusion is safe and effective for treatment of irreducible atlantoaxial dislocation.
