Abstract?AIM: To analyze the effects of femtosecond laser assisted cataract surgery ( FLACS ) in the treatment of cataract and its effect on prognosis.?METHODS:Forty-two cases (42 eyes) of patients with cataract who were treated in the Department of Ophthalmology in our hospital between January 2012 and December 2014 were selected as the study objects. According to the order of treatment, they were divided into control group and observation group, 21 cases in each. The control group was treated with traditional phacoemulsification cataract surgery ( PCS ) . On the basis, the observation group was treated with femtosecond laser. The effective phacoemulsification time (EPT), cumulative dissipated energy (CDE), fluid flow and monitored pressure of the two groups were recorded.The rate of corneal endothelial loss and the situation of Tyndall phenomenon were statistically analyzed.The two groups were followed up for 1a.The long-term visual acuity recovery was observed.The best corrected visual acuity ( BCVA ) was recorded, and the long-term complications were statistically analyzed.?RESULTS: 1 ) The total response rate in observation group was 95% while in control group was 90% ( P>0.05);2) the surgery time of the observation group was longer than that of the control group ( P<0.05) but EPT was shorter than that of the control group.CDM and liquid flow were less than those of the control group ( P<0.05 ); 3 ) at 1d after surgery, there was no significant difference in intraocular pressure between the two groups (P>0.05); the rates of Tyndall phenomenon and corneal endothelial loss in the observation group were lower than those in the control group ( P<0.05);4) BCVA of the two groups at different time after surgery were significantly higher than that before surgery (P<0.05). However, at 1d, 3mo, 6mo and 1a after surgery, BCVA of the observation group was better than that of the control group ( P <0.05 ); 5 ) the incidence of complications in the observation group after surgery (14%) was lower than that in the control group (43%) (P<0.05).?CONCLUSION: The surgical effects of FLACS in the treatment of cataract are good.After surgery, the visual acuity of patients is improved significantly and the incidence of postoperative complications is low. However, the surgery time is long and cost is high, so it is difficult to popularize.

The supramolecular inclusion properties of beta-cyclodextrin (beta-CD) and resveratrol (Res) were investigated using drug-protein interaction spectroscopy method. The differences between the results of interaction spectroscopy method and the results of classical method were compared. The total energy of the stable inclusion of cyclodextrin-resveratrol was calculated by Gaussian theory calculation. The stable inclusions in the process of interaction between resveratrol/inclusion complex and bovine lactgoferrin (BLF) were studied by molecular modeling. The results showed that the interaction spectroscopy method could explain the property of the inclusion in a more sensitive manner, it also interpreted the conveying mechanism of BLF binding with inclusion complex. The molecular modeling result showed consistent results with Gaussian theory calculation; both of the two methods obtained the stable configuration of beta-CD-Res inclusion. The relevant result provided an experimental consequence for the pharmacology research of beta-cyclodextrin-resveratrol inclusion complex as well as offering a new reference to the future research of supramolecular inclusion compound.

Objective To compare the effect of occupy effects of tumor in situ before surgery(OETS) and after neurosurgery (ANS) on neuroendocrine dysfunction and grading of neuroendocrine function in children with craniopharyngioma. Methods The grading evaluation criteria of neuroendocrine dysfunction in children with craniopharyngioma were drew up according to references and the endocrine feedback principle. Based on these grading evaluation criteria, the clinical date of 227 cases of children with craniopharyngioma who underwent neurosurgical treatment were retrospectively studied. These children were divided into pre-pubertal group (167 cases) and pubertal group (60 cases). The neuroendocrine impairment status before and after the surgery were evaluated separately. Results Among 227 children with craniopharyngioma, after the surgery, the incidence of the hypothalamus-pituitary-thyroid dysfunction increased from 16.74%(38/227) to 67.40%(153/227), the incidence of the hypothalamus-pituitary-adrenal gland dysfunction increased from 14.54%(33/227) to 44.49%(101/227), and the the incidence of pituitary function impairment increased from 17.62%(40/227) to 21.15%(48/227). Meanwhile, the incidence of body temperature dysregulation, sleeping disorder, personality abnormality and cognitive abnormality all increased after the surgery. The scoring and grading on neuroendocrine dysfunction in pre-pubertal group were increased after the surgery (Z=-5.20, P<0.01; Z=-4.94, P<0.01,). The scoring and grading on neuroendocrine dysfunction in pubertal group were increased after the surgery( Z=-4.10, P<0.01;Z=-4.25, P<0.01). Conclusions Both the mass effect of tumor in situ of craniopharyngioma and the neurosurgical treatment can be harmful to the neuroendocrine function. Even though the surgery can remove the mass effect of tumor in situ in the saddle area, it can increase the level of grading of neuroendocrine dysfunction. The status of neuroendocrine dysfunction can be evaluated by the grading evaluation criteria of neuroendocrine dysfunction in children with craniopharyngioma, which then provides an effective evaluation tool for the reconstruction and rehabilitation of neuroendocrine function.

Objective To evaluate MR findings and clinical features in patients with spontaneous spinal epidural hematoma (SSEH). Methods Eight patients (5 men, 3 women; aged 16-50 years ) with SSEH underwent MR imaging during 1994-2001, including 7 cases without history of trauma or coagulation disorders and 1 case with history of hypertension. MR imaging was performed from 4 hours to 3 days after the onset of symptoms in all 8 patients with surgical and pathologic diagnosis. Results The hematomas were in lateral posterior or posterior epidural space, including 3 cases in cervical vertebra, 2 cases in thoracic vertebra, 2 cases in cervical and thoracic junction region, and 1 case in thoracic and lumbar part. The MRI confirmed an encapsulated hematoma caused by arteriovenous malformation in 1 case and two hematomas associated with disc herniation. The signal intensity of the hematoma varied with the hematoma age, but T 1-weighted images reflected its typical signal changes. Sagittal and coronal T 1- weighted images revealed isointense (7 cases) and slight high-intense (1 case) signal; Sagittal and axial T 2-weighted images revealed mixed-intensity (6 cases) and mixed high-intensity (2 cases). Conclusion MR imaging has an important value on localization, identification, and differential diagnosis of the lesion, therefore, it is the most helpful diagnostic tool for this condition.
