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.

OBJECTIVETo assess the feasibility of usage of microbubbles conjugated with RGD peptides and contrast enhanced ultrasound (CEU) in detection of tumor angiogenesis.
METHODSLipid microbubbles (MB) were prepared, and the RGD peptides were covalently conjugated to the lipid shell of MB (MB(RGD)). Six nude mice with tumor created by dorsal inoculation of HepG2 tumor cells were used as the test group. Six nude mice without tumor were served as the control group. 10 minutes after bolus injection of MB and MB(RGD) randomly (30 min interval) via a tail vein catheter, CEU was performed on the tumors of the test group and the thigh skeletal muscles of control group. The video intensity (VI) of tumors and the skeletal muscles were measured. The tumors and the skeletal muscles were harvested for immunohistochemical examination.
RESULTSOnly a slight contrast enhancement of the tumor was seen with MB, and the VI was 5.33 ± 1.71. While a remarkable enhancement of the tumor was observed after injection of MB(RGD). The VI was up to 17.03 ± 3.58, 3.18 folds higher as compared with that obtained by injection of MB (P < 0.05). As expected, there were no obvious contrast enhancement of the skeletal muscles with both MB(RGD) and MB. There was a high expression of αvβ3-integrin in tumor neovascular endothelium, however, no apparent expression of αvβ3-integrin was observed in the skeletal muscle vascular endothelium.
CONCLUSIONCEU with MB(RGD) can be used to effectively evaluate the angiogenesis of tumors, and it may greatly contribute to the early judgement of the nature of tumor.

Fibrosis is the common end stage of most liver diseases. Unfortunately, there is no effective treatment available currently. This study was designed to evaluate the effect of Flk1+ mesenchymal stem cells (MSC) from murine bone marrow (Flk1 + MSC) on fibrosis formation induced by carbon tetrachloride (CCl4). In this study Flk1+ MSC were isolated from bone marrow of male BALB/c mice. A CCl4 induced hepatic fibrosis model was used. Flk1+ MSC were systemically infused immediately or one week after the female mice were challenged with CCl4. Fibrosis index and donor cell engraftment were assessed two or five weeks after CCl4 challenge. We found that Flk1+ MSC transplantation immediately, but not one week after exposure to CCl4, significantly reduced CCl4-induced liver damage and collagen deposition. In addition, levels of hepatic hydroxyproline and serum fibrosis markers (HA, P-III-P) in mice receiving immediate Flk1+ MSC transplantation after CCl4 challenge were significantly lower compared to those of control mice. More importantly, histological examination suggested that hepatic damage recovery was much better in these immediately Flk1+ MSC-treated mice. Immunofluorescence, PCR, and fluorescence in situ hybridization (FISH) analysis revealed that donor cells engrafted into host liver, had epithelium-like morphology and expressed albumin (ALB), although at low frequency. In conclusion Flk1+ MSC might initiate endogenous hepatic tissue regeneration, engraft into host liver in response to CCl4 injury, and ameliorate its fibrogenic effects.
