The design and efficacy of surgery for horizontal idiopathic nystagmus (HIN) with abnormal head posture and strabismus were investigated. Different surgical procedures were selected according to the angle of head turn in 44 cases of HIN with abnormal head posture and strabismus. For patients with a head turn of 15° or less, the Anderson procedure was used; the yoke muscles were recessed upon slow-phase. For patients with a head turn between 15° and 25°, the surgery was designed as a Kestenbaum 5-4-4-5 procedure. For patients with a head turn of 25° or more, the surgery was designed as a Parks 5-8-6-7 procedure. The surgery to correct the abnormal head posture was performed on the fixating eye while that to correct the deviation was then performed on the non-fixating eye at the same time. The amount of surgery of the horizontal rectus muscles on the non-fixating eye was sum of the angle of head turn and the degree of deviation, which was calculated as follows: recession/resection amount of medial and lateral rectis/2×5=angle of head turn±degree of deviation. The results showed as follows: (1) Visual acuity: the visual acuity in the primary ocular position increased two lines or more in 35 patients, accounting for 79.55%. Nine patients had no or only one-line improvement, accounting for 20.45% of the entire study population; (2) The degree of deviation in the primary ocular position: 37 cases had a normal primary ocular position or the degree of deviation ≤8(δ) after surgery, accounting for 84.09%. Six patients had a residual degree of deviation of 8(δ)-15(δ), accounting for 13.64%. One patient had a residual degree of deviation >20(δ), accounting for 2.27% of the patients examined; (3) Abnormal head posture: 34 patients had a normal head posture or a head turn of less than 5°, accounting for 72.27%. Eight patients had a residual head turn of 5°-15°, accounting for 18.18%. Two patients had a head turn of 15°-25°, accounting for 4.55%. It was concluded that different surgical procedures based on the angle of head turn and the relationship between deviation and null zone can eliminate anomalous head posture, correct deviation, and improve vision acuity in the primary ocular position.

OBJECTIVEThis study aimed to explore the effect of the up-regulation of Notch1 on osteoclastogenesis induced to osteoclasts by receptor activator for nuclear factor-kappaB ligand (RANKL) and macrophage colony-stimulating factors (MCSF) in vitro.

METHODSThe bone marrow stem cells (BMSCs) of Rosa(-notch1) mice were cultured and induced to osteoclasts by RANKL and MCSF. The BMSCs were transfected with the Ad-Cre-green fluorescent protein (GFP) virus or Ad-GFP virus. Total RNA from cells was extracted, and the gene expression levels of Notch1, Notch2, Notch3, Notch4, Deltal, Delta3, Delta4, Jagged1, Hes1, and tartrate resistant acid phosphatase (TRAP) were detected at the defined stage by reverse transcription-polymerase chain reaction (RT-PCR). Osteoclast formation was analyzed by TRAP assay.

RESULTSThe number of TRAP-positive multinuclear cells of the experimental group significantly decreased compared with that of the control group. The mRNA expression levels of Notch1, Notch3, Jagged1, Delta3, and Hesl of the experimental group were significantly higher than those of the control group, whereas the TRAP mRNA expression of the experimental group was significantly lower than that of the control group (P<0.05).

CONCLUSIONUp-regulation of Notch1 inhibit osteoclastogenesis of BMSCs induced by RANKL and MCSF in vitro.

BACKGROUND:Neural stem cel transplantation provides an important way to treat sequela of traumatic brain injury, but the timing for treatment is inconclusive.
OBJECTIVE:To explore the clinical effect of neural stem cel transplantation in the treatment of sequela of traumatic brain injury and the choice of the best treatment time.
METHODS: Totaly 178 patients with sequela of traumatic brain injury who underwent neural stem cel transplantation were divided into three groups as per the timing for neural stem cel transplantation: group A (with 6 months after injury,n=60), group B (6-12 months after injury,n=59), and group C (over 12 months after injury,n=59). Improvement in clinical symptoms and scores on function independent measure (FIM) were recorded and compared in the three groups.
RESULTS AND CONCLUSION:The total effective rate of group A was significantly higher than that in groups B and C (P < 0.05). FIM scores were significantly improved in the three groups after cel transplantation (P < 0.05). At 3 months after the fourth transplantation, the FIM score in the group A was significantly higher than that in the other two groups, and the incidence of adverse reactions in the group A was significantly lower than that in the other two groups (P < 0.05). These findings indicate that neural stem cel transplantation at different timing can al harvest certain clinical effects, but the best timing for neural stem cel transplantation is within 6 months after injury.
