AIM: To compare and analyze the stereopsis of intermittent exotropia children under the different backgrounds of dynamic stimuli and static stimuli.
METHODS: We collected 56 children ( male 26, female 30 with intermittent exotropia at the age from 5y to 12y and examined their stereopsis under the different backgrounds of dynamic stimuli and static stimuli using a multidimensional sense perception training software. The differences between the dynamic stereopsis and static stereopsis were compared.
RESULTS: Totally 17 cases ( 30%) had both dynamicstereopsis and static stereopsis, 39 cases ( 70%) had either dynamic or static stereopsis deficit, only 10 cases ( 26%) had dynamic stereopsis, 25 cases ( 64%) static stereopsis left and 4 cases ( 10%) were without any form of stereopsis. The positive rate of dynamic stereopsis was better than the positive rate of static stereopsis, with statistical significance (P<0. 05).
CONCLUSION: Dynamicstereopsis is better than the static stereopsis to intermittent exotropia children.

ObjectiveTo investigate the therapeutic effectiveness of defibrase in treating penumbra and reperfusion.MethodsIntraluminal suture method was used to develope reversible middle cerebral artery occlusion(MCAO). Rats were subjected to MCAO 3 hours followed by reperfusion for 3, 6, 24, 72 hours, and to MCAO 6 hours followed by reperfusion for 3, 6, 24 hours. The treatment groups rats were injected intravenously defibrase at 0.5 hour before reperfusion. Meanwhile, the control group received normal saline. Clinically Neurological Deficits Scale were evaluated every day. Infarction volume was measured by using 2,3,5-triphenyltetrazolium chloride staining. Pathologic change were examined microscopically in HE stained sections.ResultsThere were significant difference at treatment groups of reperfusion 3 hours after MCAO.Infarction volume and Clinically Neurological Deficits Scale was significant reduced as control group (P<0.05). There were no significant differences at treatment groups of reperfusion 6 hours after MCAO (P>0.05). Cerebral hemorrhage wasn't increased in defibrase treatment group.ConclusionsDefibrase was effective on Clinically Neurological Deficits of rats in reperfusion 3 hours after MCAO.

Objective To investigate the therapeutic effect of high intensity focused ultrasound (HIFU) ablation combined with homemade liquid fluorocarbon nanoparticles on cervical cancer in nude mice.Methods The cell experiment was divided into three groups:a,control group;b,HIFU group;c, HIFU + PFB nanoparticle group,and the viability of cells was detected using CCK-8 reagent.The mice were also divided into three groups:A,0.9% NaCI group;B,HIFU + 0.9% NaCI group;C,HIFU + PFB nanoparticle group. The tumors were removed and underwent triphenyl tetrazolium chloride(TTC) staining,and the necrosis area was measured.Histopathological changes of the tumors were examined by light microscopy.Results After HIFU irradiation,the viability rate of group c was (40.5 ±9.7)%,it was lower than that of group b (77.7 ±8.5)% (P <0.05) and that of group a(100 ±4.8)% (P <0.05). TTC staining of tumor showed a large scale of necrotic tissue in group C.The necrosis ratio of the three groups was 0%,(34.14±12.2)% and (65.97 ±25.1)%,respectively (P <0.05).HE staining showed karyorrhexis or an absence of nuclei in group B and group C,which demonstrated the coagulation necrosis. Conclusions HIFU ablation combined with liquid fluorocarbon nanoparticles can effectively treat the xenograft model of the human cervical carcinoma in nude mice.

Background Ostrich acellular corneal stroma possesses a similar constitution to human corneal stroma,so it is expected to become one of ideal biological corneal carriers.Objective This study was to investigate the immunogenicity of acellular stroma carrier of ostrich cornea and offer the information for the development of industrialization and clinical use of acellular stroma carrier of ostrich cornea.Methods Twenty fresh ostrich eyeballs and 20 porcine eyeballs were collected.Acellular corneal stroma carriers of ostriches and pigs were prepared using low temperature freezing joint enzyme digestion method and desiccant dehydration method and sterilized by cobalt-60 irradiation.The corneal stroma carriers were preserved using drying and dehydration method.Forty-five male BALB/c mice were randomly divided into the sham operation group,ostrich acellular corneal stroma group and porcine acellular corneal stroma group.Acellular corneal stroma carriers of ostriches and pigs(wet weight after rewatering was 10 mg/piece) were subcutaneously implanted to the back of BALB/c mice,respectively.Wound healing and inflammatory response on the operative site were observed,and phenotype and activating rate of CD4+,CD8+ and CD25+in peripheral blood of mice were dynamically detected 7,14 and 28 days after ectopically implantation of heterogeneous corneal stroma by immunofluorescence labeling and flow cytometry analysis.Results No swelling and exudation were seen in the skin of operative site of the mice with a good healing of wound after surgery.There were no significant differences in the activating rates of CD4+,CD8+ and CD25+ cells in the peripheral blood of mice among the sham operation group,the porcine acellular corneal stroma group and ostrich acellular corneal stroma group in the three time points after surgery(CD4+:F=0.74,P=0.50;F=0.39,P=0.05;F=3.46,P=0.58.CD8+:F=1.75,P=0.21 ;F=1.14,P=0.35;F=0.78,P=0.48.CD25+:F=0.52,P=0.61 ;F=3.53,P=0.62;F=2.42,P=0.13).Conclusions The ostrich acellular heterogeneous corneal stroma carrier possesses low immunogenicity.It is inferred that ostrich acellular corneal stroma carrier can be used in heterogeneous corneal transplantation.

Regarding the needling manipulation, Chifeng Yingyuan, there are different descriptions in ancient medical literature and the current teaching materials or clinical reports, especially for the understanding recorded in Jinzhenfu Poem of Golden Needle). In the current teaching materials and clinical reports, it is described that the needle is inserted deeply at first, and then shallowly; afterward, the needle tip is pushed to the middle layer and manipulated with lifting, thrusting and rotating technique, combined with twisting and flying method. After analyzing the original description in the book and the feasibility of function and operation, the authors introduced their recognition on its manipulation and techniques in this article. This manipulation should be: the needle is inserted to the middle layer, afterward, the needle body is pulled and tilted toward each of the four directions, on this basis, then twisting and flying method is applied.
