Causes analysis of early postoperative high intraocular pressure of angle - closure glaucoma underwent compound trabeculectomy / 国际眼科杂志(Guoji Yanke Zazhi)

To analyze the causes and treatments of high intraocular pressure ( > 21mmHg ) of angle - closure glaucoma underwent compound trabeculectomy 1mo after surgery. ●METHODS: This was a retrospective study of our hospital, from March 2010 to March 2013. Thirty-four (38 eyes) of angle-closure glaucoma patients were collected, who underwent compound trabeculectomy with high intraocular pressure ( > 21mmHg) 1mo after operation. We analyzed the causes and summarized the treatments. ●RESULTS:The causes which lead to early postoperative high intraocular pressure included malignant glaucoma (9 eyes of 8 cases), blood clot and connective tissue block under the scleral flap (15 eyes of 13 cases), hyphema after surgery(5 eyes of 5 cases), sclera flap incision was incarcerated with iris tissue ( 3 eyes of 3 cases ), preoperative high intraocular pressure for a long time(5 eyes of 4 cases), 1 eye of 1 case for unknown reason. After proper treatments, intraocular pressures of all patients were bellowed 21mmHg. ● CONCLUSlON: Early postoperative high intraocular pressure of angle - closure glaucoma underwent compound trabeculectomy is caused by various factors, and the early prevention and timely treatment are key points of a successful operation.

Clinical study of osteotome sinus floor elevation without grafting and with simultaneous implants placement / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the clinical results of osteotome sinus floor elevation (OSFE) without grafting combined with simultaneous implant placement.</p><p><b>METHODS</b>A total of 65 patients underwent maxillary sinus floor elevation from alveolus without any bone grafting from January 2000 to December 2008 and 96 implants were placed in the maxillary posterior edentulous region simultaneously. Clinical and radiography examinations were performed. The residual bone height ranged from 5 to 8 mm and the mean bone height was (6.78 ± 1.04) mm. The mean following period was 33.4 months. Statistical analysis was performed by chi square test.</p><p><b>RESULTS</b>Ninety-five of 96 implants were clinically stable and functioned without any pain and other complaints. One implant was extracted 15 days after operation because of mobility and the other implants obtained osseointegration. The mean implant protrusion length was 2.6 mm, ranging from 1 to 5 mm. Different degree of new bone formation was observed in 51 (54%) of implants. New maxillary sinus floor outline was observed in 33 (35%) of implants and there was no obvious new bone in 11 (12%) of implants. There was no significant deference between the implant protrusion length and sinus floor remodeling.</p><p><b>CONCLUSIONS</b>Under strict indications, the clinical results of OSFE without bone grafting combined with simultaneous implant placement were predictable in short term. The new sinus floor formation was not related to the implant protrusion length.</p>

Effect of two different desensitizers on bond strength of dentin bonding agents / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To evaluate the bond strength of total-etch or self-etch dentin bonding agents after using two different dentin desensitizers on exposed dentin and investigate the bond interface by scanning electron microscope (SEM).</p><p><b>METHODS</b>Thirty intact and non-carious human third molars were used. The occlusal enamel was removed with the use of a slow-speed saw under water cooling. These teeth were divided into three groups using a table of random numbers with 10 teeth each. These three groups were treated with water (Group C), UltraEZ (Group U) and MI Paste (Group M) respectively. Then 10 teeth from each group were divided into A subgroup (n = 5) bonded with Single Bond 2 adhesive system and B subgroup (n = 5) bonded with Xeno III adhesive system according to manufacturers' instructions. A block of composite resin was build up to 4-5 mm. All the teeth were sectioned occluso-gingivally to obtain bar-shaped specimens with bonded surface area about 0.9 mm x 0.9 mm. The tension of the sample was tested by a microtensile tester at 1 mm/min. The mean values of bond strength were compared using one-way ANOVA. Three samples were chosen randomly from each of six groups for SEM investigation.</p><p><b>RESULTS</b>There were no significant differences between Group U and Group C both in A and B subgroups. While there were significant differences between Group M and Group C in two bonding-agent subgroups. For SEM, the hybrid layer was thin and dense in six groups. Both total-etch and self-etch bonding systems could get fair resin tag infiltration in Group C and Group U. In Group M, the resin tags were relatively shorter and fewer than the anterior mentioned two groups.</p><p><b>CONCLUSIONS</b>UltraEZ had no effect on bond strength of both kinds of dentin bonding agents, while MI paste could diminish bond strength.</p>

Anti-fungal test of composite agastache lotion on seven pathogenic fungi and its clinical application / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the effect of Chinese composite recipe in treating mycotic infection.</p><p><b>METHODS</b>The growth condition of 7 kinds of fungi cultured on the media containing composite agastache lotion (CAL, consisted of 5 Chinese drugs) of different concentration was observed. Result showed that CAL could inhibit 7 kinds of fungi. Based on the above anti-fungus test, 110 patients with skin tinea or genital candidiasis were treated separately with CAL, western medicine and combined (CAL and western) medicines, the therapeutic effects of the 3 groups were observed and compared.</p><p><b>RESULTS</b>The therapeutic effect in patients treated with combined medicine was significantly better than that in the other two groups (P < 0.05).</p><p><b>CONCLUSION</b>Combined use of CAL and western medicine could enhance the cure rate in treating skin tinea and genital candidiasis. Attention should be paid on studying Chinese anti-fungal agents.</p>
