AIM: To compare the effects of different surgeries in the treatment of angle closure glaucoma with cataract and the improvement of quality of life.METHODS: The clinical data of 60 cases (60 eyes) with angle closure glaucoma and cataract who were admitted to the hospital between January 2014 and October 2016 were collected.According to the surgical method, they were divided into the control group (simple trabeculectomy, n=28) and the observation group (trabeculectomy combined with phacoemulsification and intraocular lens implantation, n=32).The changes of visual acuity and intraocular pressure before and after surgery were compared between the two groups.The incidence of postoperative complications was statistically analyzed, and the quality of life was compared between the two groups.RESULTS: Before surgery, there was no significant difference in visual acuity, intraocular pressure and anterior chamber depth between the two groups (P>0.05).At 4wk after surgery, the visual acuity of two groups increased and intraocular pressure decreased.The anterior chamber depth of observation group increased while that of the control group decreased (P<0.05).At 4wk after surgery, the visual acuity and anterior chamber depth of observation group were higher than that of the control group but intraocular pressure was lower than that of control group (P<0.05).The success rate of surgery and the opening rate of chamber angle after surgery in the observation group were higher than those in the control group (P>0.05).The incidence of postoperative complications in the observation group was lower than that in the control group (P<0.05).Before surgery, there was no statistically significant difference in quality of life score between the two groups (P>0.05).At 4wk and 3mo after surgery, the scores of the two groups increased (P<0.05), and the quality of life scores of observation group were higher than those of the control group at different time (P< 0.05).CONCLUSION: The success rate of trabeculectomy combined with phacoemulsification and intraocular lens implantation is high in the treatment of angle closure glaucoma with cataract.The regimen can improve the visual function, reduce the incidence of postoperative complications, and improve the quality of life of patients.

Objective: To evaluate the effects of functional appliance and multi-bracket appliance on Angle Class II malocclusions coupled with vertical and transversal problems. Methods:Headgear-activator, Herbst appliance and multi-bracket appliance were used to treat 20 patients with Class II malocclusions coupled with vertical and transversal problems aged from 10 to 15 years. The lateral cephalograms were measured with Winceph 8. 0 software and statistical analysis was carried by SPSS 13. 0 software. Results:The sagi-tal, vertical, transversal problems had mainly been resolved at the end of functional appliance treatment. The SNB were increased( P<0. 05), ANB were decreased(P<0. 05), upper posterior teeth were intruded and distally moved(P<0. 05), lower posterior teeth were extruded and mesialy moved(P<0. 05). After multi-bracket appliance treatment, the anterior teeth achieved normal overbite and over-jet. The molar relationship changed from class II to class I. Mandibular plane angle was not clockwise rotated(P>0. 05). The upper and lower dentition were harmony in sagital, vertical and transversal. Conclusion: Functional appliance combined with multi-bracket appliance can be used effectively and conveniently for the treatment of Class II malocclusions coupled with vertical and transversal prob-lems.

OBJECTIVETo study the diagnosis and microneurosurgical treatment of cavernous sinus neurinoma.

METHODSTwenty-two patients with cavernous sinus neurinoma which had been diagnosed by MRI were operated on by microsurgery. Fourteen patients received excision of tumor through frontotemporal approach with zygomatic osteotomy and, 8 patients via subtemporal and suboccipital transtentorial approaches.

RESULTSTotal resection was achieved in 21 patients (95.5%), and subtotal resection in 1. There was no operative death. The all operative samples were confirmed neurinoma pathologically. The symptoms postoperation such as headache and exophthalmos were reduced. Three months after operation, the function of the 6th nerve was improved in 12 of 19 patients with paresis of the 6th nerve. One patient with hemiplegia recovered well. The function of the 3th nerve recovered in 4 of 6 patients with recurrent paresis of the 3th nerve. Those patients with hydrocephalus were improved after operation. The patients were follow up 8 - 60 months (mean 20 months). No tumor recurrence was observed.

This study was aimed to construct miRNA sponge targeting miR-20a and to establish a stable cell line Jurkat-S, paving the way for further research on function of miR-20a and application of RNAi in gene therapy. One pair of two-repeated oligonucleotide sequences containing bulged sites that are mispaired opposite miR-20a positions 9-12 was designed and synthesized with enzyme cutting sites. The annealed oligonucleotide fragments were subcloned into pCDNA3.0-L expressing vector. After double-enzyme cutting, the vector was ligated to the annealed oligonucleotide fragments again. Enzyme cutting and luciferase activity assay were performed for identification after four repeats. Then the ligated fragment was subcloned to lentivirus expressing vector. Virus particles were collected after the control or sponge vectors were co-transfected with the psPAX2 packaging plasmid and the envelope plasmid pMD2.G into HEK-293T cells using Lipofectamine 2000. The Jurkat cells were transfused with recombinant lentivirus-transfusing units plus 6 µg/ml of Polybrene. Real-time PCR and Western blot were used to detect the mRNA and protein expression of P21 and E2F1 after lentivirus transfusion respectively. As a result, luciferase activity assay demonstrated that the sponge targeting miR-20a was constructed successfully and the virus was packaged in 293T. The titer of virus was 5×10(7) TU/ml. Stable transfected Jurkat-S cell line was established. As was expected, the mRNA and protein level of P21 and E2F1 was upregulated significantly in Jurkat-S cells. It is concluded that the miR-20a sponge is constructed successfully, and Jurkat-S stable cell line is established, in which the expression of miR-20a is inhibited stably.

OBJECTIVETo investigate the inhibition effect of fludarabine on the growth of human MDS-RAEB cell line MUTZ-1 and to explore the possible cellular and molecular mechanism.

METHODSThe apoptosis of MUTZ-1 cells induced by fludarabine was studied by transmission electron microscope, MTT assay, DNA ladder test, flow cytometry and RT-PCR method.

RESULTTreatment with fludarabine remarkably inhibited the growth of MUTZ-1 cells, the 24 h IC(50), 48 h IC(50) and 72 h IC(50) of fludarabine for MUTZ-1 cells were 137.65 mg/L, 6.27 mg/L and 0.51 mg/L, respectively. Fludarabine inhibited the growth of MUTZ-1 cells in a dose-dependent and time-dependent manner. After treated by fludarabine (1 mg/L-16 mg/L)for 24 h, MUTZ-1 cells showed the typical features of apoptosis. After fludarabine treatment the mRNA expression of Bcl-2, Bax, survivin, XIAP, cIAP-1 and cIAP-2 was not changed, but the mitochondrial membrane potential (MMP) was decreased.

CONCLUSIONWith a certain range of dose fludarabine (1 mg/L-16 mg/L)could inhibit MUTZ-1 cell growth by inducing cells apoptosis. MMP may play a certain role in apoptosis of MUTZ-1 cells induced by fludarabine.

OBJECTIVETo investigate the application of microsurgical technique in the replantation of amputated ear.

METHODS7 cases of amputated ears were analyzed from June 2009 to April 2015 in our department. We used microsurgical technique to anastomose about five vessels and nerves. The blood supply of auricle was restored within three to six hours. All subjects underwent treatments including anti-freezing, anti-spasm and anti-infection treatment after the emergency surgery.

RESULTS7 amputated ears were all survived after replantation. The patients were followed up for one month to six months ( average for 28 months). The appearances of survived ears body were fully recovered without any significant atrophy or pigmentation. The sensory function of ears recovered to normal after 1 year.

CONCLUSIONSThe application of microsurgical technique in the replantation of amputated ear can expect the high success rate of ear replantation. However, skilled and high-quality anastomosis technique of small vascular are required.
