AlM: To observe the postoperative intraocular pressure ( lOP) and operation safety in the eyes of the neovascular glaucoma pateints treated by intraocular cyclophotocoagulation which needed vitrectomy at the same time.
METHODS: A total of 12 neovascular glaucoma cases ( 14 eyes ) secondary to diabetic retinopathy, retinal detachment surgery and trauma were reviewed in our study. This procedure mainly used intraocular photocoagulation catheter to highlight the ciliary processes until the ciliary became white atrophy or plosion after vitreous surgery treatment. The intraocular photocoagulation catheter was performed at a power of 300-500mW, for a duration of 0. 1-0. 2ms. Postoperative follow-up was at least for 6mo. The observation of 14 postoperative neovascular glaucoma was performed at 1wk, 1, 6mo observing the lOP and complications.
RESULTS:lOP of the 11 eyes was significantly declined and controlled in normal. After cyclophotocoagulation, average lOP at 1wk was 16. 7±14. 4mmHg, 15. 7±8. 8mmHg at 1mo and 12. 9±4. 5mmHg at 6mo, which compared with untreatment ( 39. 6 ± 10. 0mmHg ) was statistically significant different (P<0. 01). ln follow up time 3 cases were relapsed which were supplied with transscleral or endoscope cyclophotocoagulation. During the follow-up period no endophthalmitis and complications such as eyeball atrophy were found.
CONCLUSlON: The intraocular cyclophotocoagulation and vitrectomy simultaneously can deal with the primary disease and secondary neovascular glaucoma. The operation can be accurately performed under direct cyclophotocoagulation and it is a safe and effective way for neovascular glaucoma which needs vitreous surgery.

BACKGROUND: Regeneration of type Ⅱ furcation defects of periodontal tissues is still a great clinical challenge. OBJECTIVE: To compare different densities of autologous bone marrow mesenchymal stem cells (auto-BMSCs) for repairing canine experimental class Ⅱ furcation defects of periodontal tissues. DESIGN: A randomized controlled trial. SETTING: Laboratory in Stomatological Hospital Affiliated to Fujian Medical University and Department of Animal Experiment in Fuzhou General Hospital. MATERIALS: Experiments were performed at the Laboratory in Stomatological Hospital Affiliated to Fujian Medical University and Department of Animal Experiment in Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA from July 2005 to September 2006. Six 18-month Beagle dogs were provided by Department of Animal Experiment in Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA. Animal intervention met animal ethical standards. Bio-Gide collagen membrane and BME-10X collagen membrane were used in the study.METHODS: Class Ⅱ furcation defects were induced surgically on the buccal side of canine mandibular second and third premolar (P2, P3) and first molar (M1). The ex vivo expanded auto-BMSCs from six 18-month Beagle dogs were seeded in BME-10X collagen membranes at cell density of 5×108 L-1，5×109 L-1，5×1010 L-1, and delivered into experimental class Ⅱ furcation defects, underneath a Bio-Gide membrane. Bio-Gide membrane alone was used as a control. The percentage of new cementum length and percentage of new alveolar bone area were measured on OLYPUS IX 71 inverted research microscope and OLYSIA BioAutoCell software in a computer.MAIN OUTCOME MEASURES: Each specimen was stained with hematoxylin and eosin. The lengths of new cementum and the area of new alveolar bone were calculated.RESULTS: The percentage of newly formed cementum length and the percentage of newly formed alveolar bone area were (51.5±5.6)% and (27.1±7.7)% in the control group,（84.8±8.9）% and（30.6±7.7）% in the 5×108 L-1 BMSCs group, (91.8±5.2)% and (68.3±11.4)% in the 5×109 L-1 BMSCs group and (88.8±7.2)% and (78.5±12.7)% in the 5×1010 L-1 BMSCs group. There were significant differences when comparing the BMSCs groups to the control group (P < 0.01), but there was no significant difference in each BMSCs group. There were significant differences in the percentage of newly formed alveolar bone when comparing the 5×109 L-1 and 5×1010 L-1 BMSCs groups to 5×108 L-1 BMSCs group and control group (P < 0.05), but there was no significantly difference between the first two groups, and neither was the later.CONCLUSION:Periodontal regeneration can be induced by BMSCs transplantation. The mechanism of regeneration is associated with inoculated density.

Objective To analyze mutations in the GJB2 gene in a Chinese patient with keratitis-ichthyosis-deafness (KID)syndrome complicated by cutaneous squamous cell carcinoma. Methods Clinical data were collected from a patient with KID syndrome complicated by cutaneous squamous cell carcinoma. Peripheral blood samples were obtained from the patient and her parents, and DNA was extracted from these blood samples. PCR was performed to amplify the exon 2 of the GJB2 gene followed by direct DNA sequencing. Results A mutation (c.148G > A)was identified at position 148 in exon 2 of the GJB2 gene, which caused a codon change from GAC to AAC and resulted in the substitution of aspartate by asparagine at position 50 in the connexin26 (Cx26)protein (p.Asp50Asn). Inaddition,anothermutation(c. 79G > A), which led to the substitution of valine by isoleucine at codon 27 in Cx26 (p.Val27Ile), was found at position 79 in exon 2 of the GJB2 gene. Neither of the two mutations was detected in the patient′s parents. Literature review revealed that 13 cases of KID syndrome complicated by cutaneous squamous cell carcinoma had been reported in abroad, and the mutation c.148G > A was detected in the GJB2 gene in all the 7 cases finally diagnosed by gene sequencing. Conclusion GJB2 gene mutations may be responsible for the clinical phenotype of KID syndrome in this Chinese patient, and the mutation c.148G > A may be related to the development of cutaneous squamous cell carcinoma.

Objective To explore the damage of spiral ganglion neurons(SGNs),the protective effects of different dosages of healthy ear compound (HEC)from traditional Chinese medicine(TCM) against age-induced SGNs degeneration and its possible mechanism in spiral ganglion neurons(SGNs)of C57BL/6J mice.Methods Totally 36 C57BL/6J mice just after ablactation were randomly divided into four groups.Normal control group (n =6)drank tap water daily from ablactation to 2 months old.Ageing-related SGNs apoptosis control group(n=12)drank tap water daily from ablactation to 7 months old.High dose TCM group(n=12)at drank 3.65 g/kg/d of HEC from ablactation to 7 months old.Low dose TCM group(n=6)drank 0.91 g/kg/d of HEC from ablactation to 7 months old.The animal cochleae were immediately removed at the termination of the experiment.In each group,the cochleae of 6 animals were used for paraffin embedding,slicing and toluidine blue staining to observe neuronal morphological changes.The caspase-3 mRNA expression study was performed by real-time PCR technique in 6 cochleae of High dose TCM group and ageing-related SGNs apoptosis control group.Results The morphological structure of cochlear SGNs represented healthy and normal density in normal control group at 2 months old.In contrast,amount or density of SGNs in cochlear basilar part was significantly damaged and reduced in ageing-related SGNs apoptosis control group at 7 months old(P＜ 0.001).But the high dose TCM group at 7 months of age was similar to the normal control group at 2 months old in morphological structure,amount or density of SGNs(P＞0.05).The low dose TCM group was significantly different from other 3 groups in amount or density of SGNs (P＜0.001).However,SGNs in the middle part and apical part showed integrity in each group.In addition,the expression level of caspase-3 in the cochlea of high dose TCM group was also obviously different with age-related SGNs apoptosis control group(P＜0.01) Conclusions Ageing-related damage of SGNs in C57BL/6J mice begins from the base of cochlea and progresses towards the apex.The HEC of TCM could significantly protect SGNs against age-induced apoptosis in SGNs.The efficacy of the high dose TCM is better than that of the low dose TCM.Its SGNs protective mechanisms might be related to involving the caspase-mediated cell apoptotic pathway.
