Abstract? AIM: To investigate changes of anterior chamber parameters after posterior chamber phakic implantable collamer lens ( ICL ) surgery and its correlation with intraocular pressure ( IOP) .?METHODS: This was a retrospective case series study. Seventy four eyes in 43 myopia patients were examined by Allegro Oculyzer anterior segment tomography to obtain the changes of anterior chamber volume ( ACV ) , anterior chamber angle ( ACA) , central anterior chamber depth ( ACD) and vault, meanwhile, to measure the IOP to analyze the correlation with anterior chamber parameters.?RESULTS: Compared with preoperative, ACV, ACA, ACD all decreased apparently ( P <0.01 ) in the postoperative period of 1, 3, and 6mo.ACV, ACA and ACD showed their stability in each period after the surgery.There were changes of vault in 1 and 6mo ( t=27.66, P=0.01).IOP had not altered when compared with the preoperative.This research revealed that IOP had no relation with ACV, ACA, ACD and vault in every phase( all P>0.05).?CONCLUSION:For patients underwent ICL, the anterior chamber parameters all decreased which included ACV, ACA, ACD, and had stabilized since early postoperative period. Correspondingly, IOP was stable and had not correlate with ACV, ACA, ACD and vault, however the long-term observation is still necessary.

Background Econazole nitrate is not effective as an antifungal eyedrop because of its poor intraocular permeability,therefore changing the formulation of econazole nitrate to improve its intraocular permeability become a critical point in the treatment of intraocular fungal infection. Objective The present study was to observe the penetration of 0.5％ econazole nitrate nanoparticles in the corneas and aqueous humors following its topicaladministration. Methods Econazole nitrate nanoparticles were prepared by quasi-emulsion solvent diffusion.Characteristics and size of nanoparticles were examined with transmission electron microscope and laser scatteringmethod,respectively.Econazole nitrate nanoparticles drops (0.5％ )was topically administered in 27 New Zealandwhite rabbits bilaterally,and aqueous humor and corneas were obtained after the application of the eye drops for 5,15,30,45,60,90,120,180,240 minutes respectively to detect the concentration of econazole nitrate with highperformance liquid chromatography (HPLC). The pharmacokinetic parameters were calculated with 3 p97pharmacokinetic computer software.The use of the animals followed the Regulation for the Administration of AffairsConcerning Experimental Animals by State Science and Technology Commission. Results The diameter of thenanoparticles was 50 nm with the round shape and encapsulation efficiency was 96.0％.Econazole nitrate nanoparticlesat the concentration of 0.5％ could be rapidly separated with other elements by HPLC with a lowest quantitativeconcentration of 0.1 mg/L.The mean recovery rates of econazole nitrate nanoparticles were 98.09％ in cornea and 99.66％ in aqueous humor,respectively after topical administration.The peak levels of econazole nitrate nanoparticles in cornea and aqueous humor were achieved at 5 minutes after application ( cornea:40.620 μg/g± 7.756 μg/g;aqueous humor:0.504 mg/L±0.153 mg/L),and its half-life( t1/2 )in cornea and aqueous humor was 23.5 minutes and 18.6 minutes,respectively. Conclusions Econazole nitrate nanoparticles at 0.5％ concentration can remain a feasible bioavailability in ocular tissue and therapeutic level in cornea and aqueous humor.

Objective To apply MR diffusion tensor imaging (DTI) to quantitatively analyze cervical spinal cord injury without radiographic abnormality (CSCIWORA). Methods 15 patients with CSCIWORA and 20 healthy controls were scanned with MRI of conventional scans and DTI. The fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were measured. Results FA and ADC of the patients were (0.475±0.109) and (1.438±0.252)×10-3 mm2/s, respectively. Whereas, they were (0.604±0.096) and (1.371±0.280)×10-3 mm2/s in the controls. Compared with the controls, the FA was less (P<0.05) in the patients, but the ADC was not significantly different (P=0.267). The fiber tracking (FT) showed the abnormality of white matter fiber tracts of cervical spinal cord in the patients. Conclusion DTI can detect the CSCIWORA, and FT can directly display the injuries of white matter fiber tracts of cervical spinal cord, which provide more information to evaluate the clinical severity of CSCIWORA.

Objective To investigate the preliminary experience of mechanical thrombectomy with a tri-axial system of the Solitaire AB stent through a Neuro delivery catheter to treat intracranial large artery occlusion. Methods A tri-axial system was used to deliver the Solitaire AB stent through a Neuro delivery catheter to provide intracranial aspiration in close proximity to the stent. This technique was used in 1 case of acute middle cerebral artery occlusion and 1 case of acute basilar artery occlusion. Results Successful revascularization was achieved in these 2 cases. Thrombolysis in cerebral infarction (TICI)score was 3. The clot length of acute middle cerebral artery occlusion was 3 cm and the modified Rankin Scale (mRS)score of this case was 3 at 90 days follow-up. Another patient with acute bilateral vertebral occlusion was revealed successful recanalization by angiography. Conclusion The results suggest that this technique of a tri-axial system used of the Solitaire stent through a Neuro delivery catheter can effectively retrieve clots from the occlusive artery and minimize the chance of antegrade blood flow dislodging the thrombus.

Objective To evaluate the efficacy of haploidentical hematopoietic stem cell transplantation (HSCT) with supplemental umbilical cord blood (UCB) infusion in treatment of malignant hematological diseases.Method Clinical data of 66 patients with hematological malignancies treated with HSCT in our hospital between January 2010 and May 2013,were retrospectively analyzed.Among them 25 cases received infusion of human UCB before HSCT (experimental group) and other 41 cases had no UCB injection before HSCT (control group).Results There were no differences in age,gender,donor type,disease categories,disease status before transplant between two groups (P ＞ 0.05).There was a significant difference in conditioning regimes between two groups (P ＜ 0.05),but no clinical implication.The infused mononuclear cell (MNC) count in experimental group was higher than that in control group (9.94 ± 2.88 × 108/kg vs.7.80 ±0.82 × 108/kg,P =0.00),while there were no difference in infused CD34 + cell count (5.46 ±3.54 × 106/kg vs.3.54 ± 1.60 × 106/kg,P =0.16).Neutrophil recovery time in experimental group was shorter than that in control group (13.7 ±2.9 d vs.16.6 ±2.9 d,P =0.023).The incidences of grade Ⅲ-Ⅳ acute graft versus host disease (aGVHD,P =0.036),bacterial infection (P =0.001) and fungal infection (P =0.001)and hemorrhagic cystitis (P =0.00)in experimental group were lower than those in control group.There were no significant differences in platelet recovery time(P =0.43),the incidence of grade Ⅰ-Ⅱ aGVHD (P =0.27),implanted syndrome (P =0.24),sinusoidal obstruction syndrome (P =0.57)and viraemia (P =0.31)between two groups.Conclusion HSCT with supplemental infusion of human UCB may alleviate the degree of aGVHD,but the long-term outcome remains to be studied.

Objective To investigate the effects of ciyelosporine-A(CsA).a calcinenrin(CAN)inhibitor,on electrophysiological propertiesof atria in canine tachycardia-induced model of AF.Methods Eighteen healthy adult mongrel canines weighing 17.0 to 23.2 kg(rangedfrom 2 to 4 years old)were randomized to 3 groups,Sham group(no pacemaker was implanted),atrial tachypacing group(ATP group)each group at baseline and after 8 weeks' tachypacing.Measurements included atrial effective refractory period(AERP),conductionvelocity(CV),wave length(WE),atrial fibrillation load and rate-adaptability. Results After 8 weeks' atrial tachypacing,ATP andCsA groups showed significant longer duration of the P wave,shorter AERP,decreased adaptation of AERE slower CV,shorter Wland longer AF duration compared to the shamg roup (all P＜0.05).AERP of the CsA group was longer than that of ATP group (P＜0.05),but there were no differences in rate-adaptability,CV,incidence of induced AF and AF duration between CsA group and ATP group.Conclusions Our results suggest that calcineurin pathway intervention by CsA have a positive effect on tachycardia-inducedelectrical remodeling of atria,but can not prevent or reverse AF.

Objective: To observe the clinical efficacy of herb-partitioned spreading moxibustion at Baliao points plus climen for diminished ovarian reserve (DOR). Methods: A total of 60 patients with DOR were randomized into a spreading moxibustion group and a Western medicine group by the random number table method, with 30 cases in each group. The Western medicine group was treated with climen, starting from the 5th day of the menstrual cycle for 21 d. The spreading moxibustion group was treated with herb-partitioned spreading moxibustion at Baliao points on the basis of the medication in the Western medicine group, 1 h per time, once a week. The treatment was performed for 1 month as one treatment course in both groups, for 3 courses in total. The serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in the patients were measured before and after treatment. The peak systolic velocity (PSV) and resistance index (RI) were also detected. The traditional Chinese medicine (TCM) symptom score was evaluated. The clinical efficacy was evaluated after treatment. Results: The total effective rate in the spreading moxibustion group was 93.3％, which was significantly higher than 80.0％ in the Western medicine group, and the difference between the groups was statistically significant (P<0.05). After treatment, the TCM symptom scores, the serum FSH levels, FSH/LH ratios and RI in both groups decreased, and the intra-group differences were all statistically significant (all P<0.05). The serum E2 level and PSV increased compared with those in the same group before treatment, and the intra-group differences were statistically significant (all P<0.05). After treatment, the TCM symptom score, the serum FSH level, FSH/LH ratio and RI in the spreading moxibustion group were lower than those in the Western medicine group, while the serum E2 level and PSV were higher than those in the Western medicine group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Herb-partitioned spreading moxibustion at Baliao points plus climen can produce valid therapeutic efficacy for DOR. It can improve the clinical symptoms, regulate serum hormone levels and increase ovarian blood perfusion, thus improving ovarian reserve function, producing more significant efficacy than climen alone.
