Chinese Journal of Postgraduates of Medicine 2015;38(1):38-40
Objective To discuss the clinical efficacy of comprehensive therapy in children with amblyopia.Methods A total of 137 eyes of 87 children were observed.They were given glasses,cover,fine training on the basics of their corrected visual acuity after mydriasis with atropine and optometry.According to amblyopic type,all subjects were divided into three groups,ametropic amblyopia group (96 eyes),anisometropic amblyopia group (28 eyes) and strabismic amblyopia group(13 eyes).According to treatment-starting age,they were divided into 3-6 years old group (95 eyes),7-9 years old group (25 eyes),and 10-12 years old group (17 eyes).According to amblyopic degree,they were divided into mild group(61 eyes),medium group (60 eyes) and serious group (16 eyes).According to fixation nature,they were divided into central fixation group (93 eyes),paracentral fixation group (44 eyes).Results All of subjects' eyes,87 eyes (63.50%,87/137) were basically cured,40 eyes (29.20%,40/137) were improved,and 10 eyes (7.30%,10/137) were unimproved.The total effect rate was 92.70% (127/137).The efficacy of treatment was closely related to amblyopic type,treatment-starting age,amblyopic degree and fixation nature.Efficacy of the treatment on anisometropic amblyopia was the highest among all three types.The younger the treatment-starting age,the better the efficacy of the treatment.There was a positive correlation between the mildness of amblyopia and the efficacy of the treatment.Efficacy of central fixation group was better than that of paracentral fixation group.Differences between efficacies of treatment on each group were significant (P < 0.01).Conclusion Comprehensive therapy in children with amblyopia can achieve satisfactory effects.
3.The relationship between CD44 and the resistance to antineoplastic agents of breast neoplasms
Journal of International Oncology 2009;36(7):521-524
The cell adhesion molecule CD44 antigen correlates with the antineoplastic agents resistance of breast neoplasms closely. Its high expression can enhance the invasion of the breast neoplasms. CD44 mole-cule can affect the expression of the TGF-β of breast neoplasm cells to induce the resistance to tamoxifen. The influence on erbB-2 cell signal pathway result in the resistance to the trastuzumab. CD44 can strengthen the re-sistance to anthracene nucleus by inducing expression of protein MRP2 and inhibiting the topoismerase. The modulation of survivn and multidrug resistance gene intensifies the resistance to paclitaxel.
4.Mutant hypoxia inducible factor 1alpha transfection promotes proliferation of bone marrow mesenchymal stem cells
Chinese Journal of Tissue Engineering Research 2017;21(25):3956-3963
BACKGROUND: It has been found that hypoxia inducible 1α (HIF1α) gene can improve the ability of tissues and cells to survive in the ischemic environment, which is of great significance in promoting blood vessel regeneration.OBJECTIVE: To investigate the effect of the recombinant adenovirus Ad-CMV-HIF1αmu-IRES-hrGFP-1 on the proliferation of bone marrow mesenchymal stem cells.METHODS: Passage 3 bone marrow mesenchymal stem cells were cultured and transfected with Ad-CMV-HIF1αmu-IRES-hrGFP-1 virus (experimental group), with non-mutated gene Ad-CMV-HIF1α-IRES-hrGFP (positive control group), with Ad-CMV-IRES-hrGFP-1 empty virus (negative control group), or with no virus solution (blank control group). After transfection for 24 hours, the expression of HIF1α mRNA and protein was detected. Cell proliferation was detected by MTT assay at 24, 48, 72, 96 and 120 hours after transfection.RESULTS AND CONCLUSION: (1) Except that the mRNA expression of HIF1α in the experimental group and the positive control group was significantly higher than that in the negative control group and the blank control group (P < 0.05), there was no significant difference between two groups. (2) The expression of HIF1α protein in the experimental group was significantly higher than that in the positive control group, the negative control group and the blank control group (P < 0.05), and there was no significant difference between the latter three groups. (3) Cell proliferation was faster in the experimental group than the positive control group and the blank control group (P < 0.05), and moreover, there was no significant difference between the latter two groups. Our experimental findings indicate that the recombinant adenovirus-mediated three-point mutant HIF1α combined with hrGFP gene transfected bone marrow mesenchymal stem cells could not only express the target protein, HIF1α, under normoxic conditions, but also promote the proliferation of bone marrow mesenchymal stem cells.

9.Propofol intervention affects spinal cord edema and hindlimb electrophysiology in a model of spinal cord injury
Chinese Journal of Tissue Engineering Research 2016;20(5):640-645
BACKGROUND:A large number of studies have verified that propofol could effectively reduce secondary nerve injury by improving microenvironment of spinal cord injury. OBJECTIVE: To study the effects of propofol on spinal cord edema and electrophysiology of the hind limb in rats with spinal cord injury. METHODS: Rat models of acute spinal cord injury were established by using the modified Alen method. A total of 40 rat models were randomly divided into spinal cord injury group and propofol group (n=20). Rats in the propofol group were injected with propofol through the caudal vein. The spinal cords of an additional 20 rats were exposed in the sham surgery group. Motor function was evaluated using BBB score and inclined plate test before modeling, 1, 3 days, 1-4 weeks after modeling. Neuronal apoptosis was detected after spinal cord injury using TUNEL assay at 72 hours after modeling. AQP4/9, matrix metaloproteinases 9/2 mRNA and protein expressions were measured using RT-PCR and western blot assay. At 4 weeks after modeling, pathological changes of the spinal cord were observed using immunohistochemistry and hematoxylin-eosin staining. Neurophysiological recovery was analyzed using motor evoked potentials and somatosensory evoked potentials. RESULTS AND CONCLUSION: (1) At 1-4 weeks after modeling, BBB score and inclined plate test score were higher in the propofol group than in the spinal cord injury group (P < 0.05), but lower than in the sham surgery group (P < 0.05). (2) The number of apoptotic cels was significantly more in the spinal cord injury group than in the propofol group (P < 0.05). No apoptotic cels were found in the sham surgery group. (3) At 72 hours after spinal cord injury, AQP4/9 and matrix metaloproteinases 9/2 mRNA and protein expression was higher in the propofol group than in the sham surgery group (P < 0.05). AQP4/9 and matrix metaloproteinases 9/2 mRNA and protein expression was significantly reduced in the propofol group (P < 0.05). (4) At 4 weeks after modeling, the spinal cord was loose, and the cavity was smal. Partial neuronal necrosis could be seen. The degree of nerve fiber density in the propofol group was between the sham surgery group and spinal cord injury group. (5) Motor evoked potentials and somatosensory evoked potentials were obviously recovered, the latency was short, amplitude was increased in the propofol group, which showed significant differences as compared with the sham surgery group and the spinal cord injury group (P< 0.05). Results suggested that propofol can reduce apoptosis in rat neurons after spinal cord injury, reduce spinal cord edema-related gene expression, and improve electrophysiological function and limb motor function.
