AIM: To evaluate the therapeutic efficacy and safety of heavy silicone oil (HSO), Densiron 68, was used as internal tamponade to treat complex vitreoretinopathy.METHODS: A retrospective study of 30 patients (30 eyes) who underwent vitrectomy and HSO tamponade for complex retinal detachment between January 2015 and January 2016.The best corrected visual acuity (BCVA), intraocular pressure (IOP), retinal reattachment and complications after surgery were observed.RESULTS: There were statistical significances in both the BCVA difference between pre-operation and HSO tamponade, and the BCVA difference between pre-operation and the removal of HSO for 3mo (z=-2.198, P=0.028;z=-2.682, P=0.007).The average intraocular pressure of HSO tamponade group was 20.233±8.007mmHg, and the average intraocular pressure of pre-operation group was 16.067±4.025mmHg, showing significant difference(t=-2.913, P=0.005).Between the pre-operation group and the HSO removed group 14.933±3.423mmHg, there was no significant statistical difference in the analysis of IOP (t=2.635, P=0.430).Anatomical success was achieved in 90% of cases after the removal of HSO.Most common complications were cataract formation and oil emulsification.CONCLUSION: Densiron-68 is a safe and effective tamponade material for the treatment of complex vitreoretinopathy.However, most common complications are cataract formation and oil emulsification.So clinicians should strictly handle indications and usage during the clinical applications.

Rhamnolipid,an important biosurfactant,is reviewed with respect to chemical strocture,properties,physiological role and their fermentation production,especially focusing on the production with inexpensive raw materials,such as vegetable oils and residues from agro- industrial wastes.This can not only reduce the production costs,but also contribute to the reduction of environmental impact generated by the discard of residues,and the treatment costs.

?AlM: To observe the expression of Acin1 ( apoptotic chromatin condensation inducer 1 ) in congenital cataract mouse retina during development and investigate the differences of retinal apoptosis and the connection of lens and retina development between congenital cataract mouse and normal mouse.
?METHODS: There were congenital cataract mice ( 10 female and 5 male) and normal C57BL/6 mice (10 female and 5 male) . One male and two female mice were fed in the same cage randomly. The young mice were divided into two groups: congenital cataract group and normal control group. Five young mice were treated each group on 1, 5, 9, 14, 17, 21, 26, 60d. The left eyes were fixed with 4% neutral formalin to detect AClN1 protein by immunohistochemistry and retinas from right eyes were used to detect the mRNA expression of Acin1.
?RESULTS: Acin1 had sustained expression in each group. AClN1 protein gradually expressed from the ganglion cell layer, inner nuclear layer to the outer nuclear layer following retinal development. lt mainly expressed on ganglion cell layer and inner nuclear layer, but not neuroblastoma layer. AClN1 protein positive cells on P1 ~ P14d increased in normal control group, P17d reduced, after P21d positive cells of each layers decreased. The overall trend was similar in congenital cataract group with normal control group, P1 ~ P14d positive cells count was lower than normal control group, P17-P21d positive cells were flat and higher than the normal control group. Compared with the same day of the two groups, the differences except for P17, P26, P60d were significant (P<0. 05). The overall difference was statistically significant in congenital cataract group ( Fcataract=295. 07, P<0. 01);in addition to P1 and P5, P17 and P21, the differences were statistically significant ( P< 0. 05 ) compared with each other in congenital cataract group. The overall difference was statistically significant in control group (Fnormal=214. 21, P<0. 01); in addition to P1 and P5d, the difference was statistically significant ( P<0. 05) compared with each other in control group. The expression of P17d in congenital cataract group was lower compared with that of P14d in control group, the difference was statistically significant (P<0. 05). Acin1 mRNA trends of two groups were similar with AClN1 protein. Compared with the same day of the two groups, the difference was significant except for P17, P21, P60d (P<0. 05 ) . The overall difference was statistically significant in each other of the two groups ( Fcataract=522. 29, P<0. 01;Fnormal=472. 05, P<0. 01). The difference was statistically significant compared with each day in control group ( P<0. 05). Compared with all the rest of days except for P21 and P26d, the difference was statistically significant in congenital cataract group (P<0. 05).
?CONCLUSlON: Acin1 exist differential expression of time and space in mouse retina during development, congenital cataract crystal developmental disorder may affect the expression of Acin1 and retinal cell apoptosis and development.

Objective To observe the effect of evidence-based nursing on improvement of preoperative fears and perioperative quality of life in patients undergoing general surgery. Methods 160 cases of general surgery patients in our hospital from September 2009 to September 2010 were chosen as the research object.The 160 cases were divided into the control group and the observation group with 80 cases in each group.The control group was taken with perioperative routine care.The observation group was given evidence-based nursing.The preoperative fear score (FAVS),perioperative quality of life (QOL)score and treatment compliance for the two groups were compared. Results The fear scores for the two groups of patients before treatment were compared.The score in the observation group was significantly lower than the control group,the difference was significant.The scores of preoperative and postnperative quality of life for the two groups were compared.The patients of the observation group were significantly higher than the patients of the control group,the difference between the two groups was significant.The treatment compliance of the observation group was better than that of the control group. Conclusions The evidence- based nursing model can improve preoperative fears and perioperative quality of Wife of patients undergoing general surgery,improve patients' treatment compliance,and promote the success of operation and recovery of patients.It is worthy of clinical application.

Objective To investigate the role of electromyography(EMG) in diagnosis of nervous system diseases in children.(Met)-hods EMG tests were carried out in 354 patients with nervous system diseases,and the data and results of EMG tests were analyzed.Results One hundred and sixty-six patients′ results of EMG were abnormal.Among these abnormalities,36 cases were myogenic,47 cases were neurogenic,abnormalities of 69 cases were located in peripheral nerves,3 cases got positive in repetitive nerve stimulation(RNS),and 11 cases were on the borderline.In 36 myogenic patients,clinical diagnosis were as follow: progressive muscular dystrophy(PMD,18 cases),polymyositis(2 cases),mitochondrial encephalomyopathy(1 case), and the other 15 cases had no definite diagnosis.In 47 neurogenic patients,the diagnosis were spinal muscular atrophy(SMA,29 cases),sequela of poliomyelitis(2 cases),acute transverse myelitis(ATM,4 cases),and the other 12 patients had no definite diagnosis.In 69 cases of peripheral nerve abnormality,diagnosis were injury of brachial nerve(23 cases),hereditary motor sensory neuropathy(HMSN,2 cases),Guillain-Barre syndrome(GBS,9(ca)-ses),chronic inflammatory demyelinating polyradiculoneuropathy(CIDP,1 case),injury of facial nerve(4 cases),injury of common(pe)-roneal nerve(6 cases),metachromatic leukodystrophy(MLD,1 case),and the other 23 patients had no definite diagnosis.Three patients who got RNS positive were all diagnosed myasthenia gravis(MG),and ocular type(1 case),general type(2 cases).Eleven patients whose EMG results were borderline were all diagnosed indefinitely.One hundred and eighty-eight patients had normal results of EMG test.The diagnosis of these patients were included ocular MG(21 cases),cerebral palsy(CP,5 cases),ATM(2 cases),polymyositis((1 case)),and some other nervous system diseases(21 cases),and the other 138 were diagnosed indefinitely.Conclusions 1.EMG plays an important role in definite diagnosis of PMD,SMA,poliomyelitis and nerve injury;2.EMG can provide clue or basis in the differential(dia)gnosis of nervous system diseases which involved lower motor unit;3.EMG test has very low positive results in children with MG;(4.EMG) has little help in diagnosis of diseases involved upper motor unit only.
