To investigate the effects of Tacrolimus ointment on patients with erosive oral lichen planus. A total of 62 cases were collected and divided into two groups randomly: 31 cases were treated with Tacrolimus ointment (treatment group), and 31 cases with clobetasol propionate ointment (control group). There was no significant difference between two groups of the effective rate and side-effect occurrence during the therapy, and relapse rate within six months after treatment. The results of the present work demonstrate that Tacrolimus ointment is an effective therapy for oral lichen planus.

Objective To investigate the different expression of NF-κB p65 Protein in placental tissues between premature delivery and term delivery and to explore the significance of nuclear factor kB (NF-κB) protein expression in preterm delivery. Methods Fifty premature delivery pregnant women and thirty term delivery pregnant women ( were enrolled in this study. According to the way of delivery , the patients were divided into two groups. The expression of NF-κB p65 protein was analyzed by using immunohistochemistry method in the placental tissues. Results In the term delivery, NF-κB p65 was mainly negative or weak positive expressed in the cytoplasm of cells in the placental tissues. There was no demonstrable difference in immunostaining of the NF-kB p65 subunit in the placental tissues including chorion, umbilical cord and fetal membranes before and after labor ( P ＞ 0.05 ). In the premature delivery, NF-κB p65 was strongly expressed in the cytoplasm and nuclear of cells. The expression of NF-κB p65 protein in chorion and fetal membranes from premature delivery( 18% ,56% ) was significantly higher than that from normal pregnant women (6.7% ,13.3%, P ＜0.01 ). But no significant change was found for NF-κB p65 expression in umbilical cord in pregnant women with or without premature delivery ( P ＞ 0.05 ). And in fetal membranes and deciduas, there was a significant increase in the staining of immunoreactive NF-κB p65 in preterm(52.9% ,58.8% ) by caesarean section compared to tissues obtained from term delivery( 13.3%,6.7%, P ＜0.01 ). In chorion and fetal membranes, there was significant increases in the staining of immunoreactive NF-κB p65 in preterm ( 24.2%, 57.6% ) by vaginal dehvery compared to tissues obtained term delivery (6.7%, 13.3%, P ＜0.01 ). Conclusion In this study, the expression of NF-κB p65 did not show significant change in term delivery before and after labor. NF-κB p65 in premature delivery was higher than term delivery, and it had no relationship with the delivery ways.

Objective:To investigate the value of NMO-IgG in diagnosis of neuromyelitis optica(NMO).Methods:A total of 120 patients with NMO,including high-risk NMO(HR-NMO),multiple sclerosis(MS),and other neurological diseases were enrolled in the study.The titres of serum NMO-IgG in all patients’ were detected by indirect immunofluorence.Results:The sensitivity and specificity of NMO-IgG were 67%,92% respectively in diagnosis of NMO.There were significantly differences in serum NOM-IgG posieivity among patients with NMO and MS who experienced severe optical neuritis,transverse myelitis,spinal-cord lesion beyond 3 segments as well as the patients with normal MRI scan in brain brain normal in MRI scan,serum and accompanied with other immunological disorders(P

This study was aimed at to investigating the protective effect of a combined treatment with glial cell line derived neurotrophic factor (GDNF) and neurotrophin 3 (NT 3) on noise induced outer hair cell (OHC) damage. Guinea pigs were subjected to receiving infusion of an artificial perilymph containing GDNF (100ng/ml) and NT 3 (2 5?g/ml) into one cochlea via a mini osmotic pump. Three days later, the animals were exposed to a 4kHz narrow band noise at 115 dB SPL for 4h. The control animals received the same treatment except GDNF and NT 3. Thresholds of auditory brainstem responses (ABRs), elicited by clicks, were measured before and 3 days after the surgery of the pump implantation, and 10 days following noise exposure. Then, the subjects were sacrificed and the cochleas were stained with Hoechst 33342. The specimens were examined under a fluorescence microscope for quantitative assessment of the OHC nuclear morphology. The results showed that compared with the control animals, the drug treated ones had significant less swollen OHC nuclei ( P

Objective To observe the space-time patterns of damaged outer hair cells(OHCs) in rat cochlea at the early stage after exposure to impulse noise. Methods Wistar rats were exposed to 100 emissions of impulse noise (3 seconds interval between each emission) at 154 dB SPL. Four times (10 min, 30 min, 3h and 6h) after the noise exposure, the animals were sacrificed and the organs of Corti were processed for detection of OHC death modes. The apoptotic and necrotic OHCs were distinguished by propidium iodide (PI), a fluorescent probe specifically labeling the nuclear DNA. The specimens were examined under a fluorescence microscope for assessment of OHC damage. Results Nuclear chromatin began to shrink as the chromatin condensed around the nuclear periphery. The peripheral chromatin ring condensed into discrete mass. Chromatin masses appeared to bleb off from the nuclear surface, forming apoptotic bodies at 10 min after the noise exposure. There were a few swollen nuclei appeared 30 min after the noise exposure. Loss of OHC nuclei could be seen 3 h after the noise exposure. The cochlear lesion expanded to contain a large number of missing OHCs and seriously shrunken nuclei at 6 h after the noise exposure. Conclusions The results of the study indicate that death of OHCs takes place extremely rapid after the impulse noise exposure. The apoptosis of OHCs precedes necrosis. OHC apoptosis is a quick process. Most of dead outer hair cells were eliminated 6 h after the noise exposure.

Objective To make a quantitative analysis of damaging hair cells,and investigate the progression pattern of cochlear pathology and the primary death pathway of hair cells in cochleae of aging Fischer 344 rats.Methods Thirty-two Fischer 344 rats were used in this experiment.The animals were assigned to two groups:rats in young group (n=13) were 3-4 months old,and in aging group (n=19) were 20-27 months old.Rats in aging group were further divided into two subgroups based on the animals' age:20-23-month subgroup (n=13) and 24-27-month subgroup (n=7).The auditory brainstem response (ABR) thresholds of both ears elicited with tone bursts at 5,10,20 and 40 kHz were measured in both young,and aging Fischer 344 rats.Upon completion of the auditory test,animals were decapitated,and both left and right bullae were exposed.Following fixation,whole specimens comprising the basilar membrane with Corti organ were separated from the modiolus.Propidium iodide (PI),a popular DNA intercalating fluorescent probe was used to trace the morphological changes in hair cell nuclei,and a terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay was used to detect nuclear DNA fragmentation in the aging cochleae.Filamentous actin (F-actin),an important structural protein of outer hair cells (OHCs),was stained with FITC-labeled phalloidin to illustrate the morphologic viability of cuticular plate and the stereocilia for affirming the missed OHCs.Each Corti organ was thoroughly inspected from the apical to the basal turns of the cochlea under a fluorescence microscope.The numbers of damaging OHCs including missed nuclei,condensed nuclei and swollen nuclei were documented,and a cochleogram was drawn.Results There were significant thresholds at all tested frequencies between the young and aging rats (P
