AIM: To discuss the clinical efficacy of fresh amniotic membrane ( AM ) during the microscopic adjustable suture surgery in children's intercommunity strabismus, in order to guide clinical treatment.
METHODS: With the clinical randomized control study (RCT), 60 (112 eyes) cases of patients in childhood who received microscopic strabismus surgery in our hospital were divided them into two different groups from Jan. 2010 to Oct. 2015. According to the application of AM on the basis of ophthalmology outpatient number, 30 cases (58 eyes) in group A were treated with rectus muscle recession surgery combined adjustable suture combined with AM. The other 30 cases (54 eyes) in group B were treated with rectus muscle recession surgery combined adjustable suture only. All patients in two groups were followed-up over 6mo after the strabismus surgery.
RESULTS:Twenty-seven cases ( 48 eyes ) of all the strabismus patients must be adjusted after strabismus surgery, and the eye position adjustment rate was 42.9%. At 1mo after surgery, eye position of 18 cases (29 eyes) can be adjusted in all patients, and 44. 8% (16 cases, 26 eyes ) in group A with the average of adjustment lengths was 2. 56±0. 64mm, and 5. 6% ( 2 cases, 3 eyes ) in group B, with the average of adjustment lengths was 0. 52±0. 28mm, the differences of the adjustment rate and the average of adjustment amount were both high statistically significant (χ2 =22.477, P<0. 01; t=16. 502, P<0. 01 ) between the two groups. Except of 3 cases who couldn't cooperate with eye position adjustment, they all received eye position adjustment in different degrees in one month after strabismus surgery,and after eye position adjustment, 27 cases (53 eyes) in group A got normal eye position, and the correction rate of eye position was 91. 4%, and 16 cases (28 eyes) in group B got normal eye position after eye position adjustment, the correction rate was 51. 9%, the differences of the correction rate were statistically significant (χ2=21. 827, P<0. 01) between the two groups.
CONCLUSION: The application of fresh AM in the microscopic adjustable suture strabismus surgery is exactly effective in treatment of children's intercommunity strabismus. It can significantly extend the adjustment time and increase the adjustment amount, and it also can statistically improve the controllability and achievement ratio for children's strabismus surgery.

Objective To analyze MRI features of neurogenic bladder caused by tethered spinal cord. Methods MRI manifestations of 22 patients with neurogenic bladder due to tethered spinal cord were retrospectively analyzed.Results & Conclusion MRI can display the position of the spinal cord and the cause of tethered cord syndrome. Spinal deformations can also be displaied clearly. The characteristic signs of neurogenic bladder due to tethered spinal cord were the lower position of medullary cone (below L1～L2) and localized thickening or protrusion of the bladder wall.

UNLABELLEDTo study the androgen dependence of the neurotransmitter, calcitonin gene-related peptide (CGRP) in rat penis.

METHODSForty-four Sprague-Dawley rats were randomly divided into Group A (intact controls), Group B (castrated) and Group C (gavaged with finasteride 4.5 mg.kg(-1).day(-1)). Four and ten weeks later respectively, half of rats in each group were anaesthetized. Blood samples were taken for the measurement of serum testosterone and dihydrotestosterone (DHT) by means of radioimmunoassay. Penile samples were harvested for the investigation of calcitonin gene related peptide (CGRP)-immunoreactive nerve fibers with immunohistochemistry. The computer-assisted imaging analysis system was applied to calculate the area proportion of the CGRP-positive nerve fibers (CGRP-PNF) in each group.

RESULTS1) Both 4 and 10 weeks later, testosterone and DHT levels in Group B decreased significantly compared with those in Group A, (P <0.05, P <0.01, respectively); DHT level in Group C was also significantly decreased in comparison with that in Group A for both 4- and 10- week animals (P <0.05); 2) There was no significant differences in area proportion of CGRP-PNF among Groups A, B and C 4 weeks after treatments (P >0.05); However, 10 weeks later, the proportion of CGRP-PNF in Groups B and C was significantly less than that in Group A (P <0.01); 3) The proportion of CGRP-PNF of 4-week animals in Groups B and C was significantly higher than that of 10-week animals (P <0.05).

CONCLUSIONThe expression of neurotransmitter, CGRP may depend on androgens, including testosterone and DHT in rat penis.

OBJECTIVETo explore the patterns of innervation of cervical facet joints and determine the pathways from facet joints to dorsal root ganglions (DRGs) in order to clarify the causes of diffuse neck pain, headache, and shoulder pain.

METHODSForty-two male-Sprague-Dawley rats, weighing 250-300 g, were randomly divided into three groups: Group A (n=18), Group B (n=18), and Group C (n=6). Under anesthesia with intraperitoneal pentobarbital sodium (45 mg/kg body weight), a midline dorsal longitudinal incision was made over the cervical spine to expose the left cervical facet joint capsule of all the rats under a microscope. The rats in Group A underwent sympathectomy, but the rats in Group B and Group C did not undergo sympathectomy. Then 0.6 microlitre 5% bisbenzimide (Bb) were injected into the C1-2, C3-4 and C5-6 facet joints of 6 rats respectively in Group A and Group B. The holes were immediately sealed with mineral wax to prevent leakage of Bb and the fascia and skin were closed. But in Group C, 0.9% normal saline was injected into the corresponding joint capsules. Then under deep re-anesthesia with intraperitoneal pentobarbital sodium (45 mg/kg body weight), C1-C8 left DRGs in all rats and the sympathetic ganglions in Group B were obtained and the number of the labeled neurons was determined.

RESULTSNeurons labeled with Bb were present in C1-C8 DRGs in both Group A and Group B, and sympathetic ganglions in Group B. In the C1-2 and C3-4 subgroups, labeled neurons were present from C1 to C8 DRGs, while in C5-6 subgroups they were from C3 to C8. The number of Bb(+) neurons after sympathectomy was not significantly different in the injected level from that without sympathectomy. But in the other levels, the number of Bb(+) neurons after sympathectomy was significantly less than that without sympathectomy.

CONCLUSIONSThe innervation of the cervical facet joints is derived from both sensory and sympathetic nervous system, and DRGs are associated with sympathetic ganglions through nerve fibers outside the central nerve system.
