Objective:To evaluate the nasal safety of gastrodin nasal temperature-sensitive in situ gel through the studies on cilia toxicity in toads and mucosal irritation in rats. Methods:The toads were randomly divided into four groups, saline group, gastrodin in situ gel group, blank gel matrix group and sodium deoxycholate group, and the cilia toxicity was observed in vivo by a toad palate meth-od. The rats were randomly divided into three groups, saline group, gastrodin in situ gel group and blank gel matrix group, and the mucosal irritation was studied in rats through the observation of nasal mucosal pathological changes and behavioral indices. Results:Compared with the saline group, gastrodin in situ and blank gel matrix showed no notable effect on the cilia movement function in toads, and the effect on cilia movement of sodium deoxycholate showed statistically significant difference when compared with that of sa-line, gastrodin in situ gel and blank gel matrix (P<0. 01). During and after the treatment, no sneezing appeared in the rats. Com-pared with that in the saline group, the number of scratching nose in the gastrodin in situ gel group and blank gel matrix group in-creased (P<0. 05) without difference between the groups (P>0. 05), and after the 2-day withdrawal, that in the gastrodin in situ gel group and blank gel matrix group decreased significantly when compared with that at the last administration (P<0. 05) and showed no notable difference when compared with that in the saline group (P>0. 05). The number of inflammatory cells in the nasal mucosa in the gastrodin in situ gel group and blank gel matrix group increased complicated with congestion and cilia falling off, and after the with-drawal, the mucosal morphology in the three groups showed no significant difference. Conclusion:The local application of gastrodin in situ gel has high security, which is valuable to be studied further.

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.

AIM:To evaluate the repeatability of axial length (AL) and anterior chamber depth (ACD) obtained by A scan ultrasonography, and to compare AL and ACD obtained by A scan with those obtained by IOL Master.METHODS:Two hundred and fifty-seven cataract eyes of 170 patients were included.IOL Master and A scan were performed for each eye.Five measurements of IOL Master and 3 measurements of A scan were obtained.All the tested eyes were divided into 5 groups according to AL obtained by A scan:Group A (2129mm, 21 eyes).Cronbach's Alpha coefficient and intraclass correlation coefficient (ICC) were applied to evaluate the repeatability of AL and ACD obtained by A scan.Paired t test and Pearson correlation coefficient were used to analyze the differences and correlations of AL and ACD obtained by the 2 devices, respectively.Bland-Altman plots were presented to analyze the agreements of AL and ACD obtained by the 2 devices.RESULTS:All the Cronbach's Alpha and ICCs of AL and ACD values were more than 0.98.The differences of AL values between A scan and IOL Master were-0.11±0.08mm in Group A,-0.15±0.10mm in Group B,-0.19±0.15 mm in Group C,-0.29±0.16mm in Group D and-0.45±0.29mm in Group E, respectively (all P<0.01).The differences of ACD values between A scan and IOL Master were-0.10±0.16mm in Group A,-0.06±0.13mm in Group B,-0.06±0.13mm in Group C,-0.19±0.10mm in Group D,-0.18±0.21mm in Group E, respectively (all P<0.01).In all groups, the AL and ACD values obtained by A scan and IOL Master presented good correlations (all r>0.89, all P<0.01).CONCLUSION:The AL and ACD values in cataract eyes obtained by A scan were repeatable.The AL and ACD values obtained by A scan were smaller than those obtained by IOL Master.With the increase of AL values, the differences of AL values between A scan and IOL Master increased.

AIM: To observe the role of confocal microscopy in infectious keratitis management.
METHODS:Totally 466 patients (467 eyes) diagnosed as infectious keratitis from January 2010 to December 2013 were retrospectively studied. the corneas were examined early by in vivo confocal microscopy. The characteristics of their images and clinical features were studied and summarized.
RESULTS:All patients were recorded, the average age was 54. 4±13. 0 years, in which 264 cases (56. 7%) were male, and 202 cases ( 43. 3%) were female. In the 466 patients, 190 (40. 8%) were fungal keratitis, 148 (31. 8%) were viral keratitis, 125 (26. 8%) were bacterial keratitis and 3 ( 0.6%) were acanthamoeba keratitis. There were fungal hyphae in the images of fungal keratitis. Amebic cysts were found in acanthamoeba keratitis.
CONCLUSION:Confocal microscope can help the early diagnose and treatment of infectious keratitis. It is a noninvasive imaging technique that provides high resolution images of ocular structures at a cellular level and infectious keratitis represents one of its most important clinical uses.

Objective To establish a novel flow cytometric crossmatch assay allowing detection of complement-fixing donor specific anti-HLA IgG alloantibodies (Flow cytometry complement-dependent crossmatch,Flow-CDC). Methods One hundred pretransplant crossmatchings were performed using Flow-CDC and NIH-CDC between 62 patients awaiting renal transplantation and 33 donor cells.These crossmatchings were divided into two groups according to PRA.Group 1 consisted of 25 sera with negative PRA,and group 2 consisted of 75 sera with positive PRA.All of the sera were pretreated with DTT to inactivate IgM. Lymphocytes were isolated from peripheral blood (or,in a few instances,from the spleen) of the cadaveric donors. The correlation between different techniques for detection of donor specific anti-HLA antibodies was evaluated.The effect of both methods on clinical transplantation outcome was observed. Results In group 1,NIH-CDC and Flow-CDC were negative for all 25 sera.In group 2,24 (32.0%) had a positive NIH-CDC,31 (41.3%) had a positive Flow-CDC.There was a significant difference between two methods (?2=5.14, P= 0.016 ).Overall concordance between both tests was 93% with 69 concordant negatives and 24 concordant positives. The correlation coefficient (r) was 0.80.In group 2,5 patients received transplantation. One of them with negative NIH-CDC and positive Flow-CDC suffered from acute rejection after transplantation and lost the graft,and the other patients with negative NIH-CDC and Flow-CDC had good outcome. Conclusions Flow-CDC can detect specifically complement-fixing IgG alloantibodies against donor HLA and is more sensitive than NIH-CDC.Additionally,the computer printouts represent a permanent record of the crossmatch for retrospective review.Flow-CDC may become the standard crossmatch method as a possible alternative to conventional NIH-CDC testing.
