Background and purpose:The ovarian mucinous tumor is one of the major subtypes of the ovari-an epithelial cancer. Ubiquitination is one of the main post-translational modifications, which has proven to be involved in tumorigenicity. Deubiquitinase is the protein enzyme that could reverse the process of ubiquitination to affect the initiation and progression of malignancies. This study aimed to analyze the expression and clinical application of deubiquitinase OTUB1 (OTU deubiquitinase, ubiquitin aldehyde binding 1) in ovarian primary mucinous tumors. Methods:This study collected 90 cases of ovarian primary mucinous tumors during 2010-2015 in Obstetrics and Gynecology Hospital of Fudan University, and then collected the clinicopathological information and performed the immunochemistry.Results:Fourteen out of 90 cases were ovarian primary mucinous cystadenoma, 17 were borderline mucinous tumor (intestinal type and intraepithelial carcinoma), and 59 were ovarian primary mucinous carcinoma. The expression rate and intensity of OTUB1 were much higher in malignant cases than those in benign ones (P<0.05). The expression rate and intensity of OTUB1 were much higher in cases with mucinous intraepithelial carcinoma than those in cases with intestinal type borderline mucinous tumor (P<0.05). The expression rate and intensity of OTUB1 increased with the advance of FIGO staging (P<0.05). The expression rate and intensity of OTUB1 were much higher in cases with involved fallopian tubes than those in cases without involved fallopian tubes (P<0.05). The expression rate and intensity of OTUB1were much higher in cases with involved uterus and omentum than those in cases with-out involvement (P<0.05). The expression rate and intensity of OTUB1were much higher in cases with lymph node metastasis than those in cases without involvement (P<0.05).Conclusion:There is significant difference in OTUB1 expression between ovarian primary mucinous carcinoma and benign mucinous cystadenoma. It is highly correlated to FIGO staging and invasion and metastasis of tumor. OTUB1 could be used in differential diagnosis and in monitoring the tumor initiation and progression in ovarian mucinous carcinoma.

AIM　To determine whether ONO-1078 {pranlukast, 4-oxo-8-［p-(4-phenylbutyloxy) benzoyl-amino]-2-(tetrazol-5-yl)-4H-1-benzopyran hemihydrate}, a potent leukotriene antagonist, has protective effect on focal cerebral ischemia in mice. METHODS　Focal cerebral ischemia was induced by permanent middle cerebral artery (MCA) occlusion in mice. ONO-1078 (0.01, 0.05, 0.10 mg*kg-1), dexamethasone (0.5 mg*kg-1), nimodipine (0.2 mg*kg-1) or saline (control) were injected ip once daily for 3 days, and 30 min before MCA occlusion. Twenty-four hours after cerebral ischemia, the neurological scores were evaluated, infarct volumes and areas of the right and left cerebral hemispheres were measured by computer imaging analysis. RESULTS　ONO-1078, dexamethasone and nimodipine reduced the neurological scores. ONO-1078 and dexamethasone reduced the ratio of right/left hemisphere area, indicating inhibition of brain edema, while nimodipine showed no effect. ONO-1078 dose-dependently reduced infarct size, and dexamethasone and nimodipine showed the same effect. CONCLUSION　ONO-1078 showed protective effect on focal cerebral ischemia. This may represent a novel approach to the treatment of acute cerebral ischemia.

To investigate the etiology and pathogenesis of cholesteatoma otitis media accompanied by cholesterol granuloma and the relationship between cholesteatoma and cholesterol granuloma, 63 cases of middle ear cholesterol granuloma treated in our hospital during the period from March 1988 to May 2000 were retrospectively reviewed. All cases were surgically and pathologically verified. 15 cases of cholesteatoma coexisting with cholesterol granuloma were found among the 63 patients. All 15 cases had a long-term history of otitis media, such as otorrhea (sanguine purulent otorrhea and bloody otorrhea in 8 cases) and perforation of the eardrum (perforation of pars flaccida in 8 cases). Temporal bone CT scans showed cholesteatoma in 11 cases. All patients were treated surgically, and cholesteatoma and cholesterol granuloma were found coexisting alternately, the latter lying mainly in the tympanic antrum, attic and mastoid air cells. Chocolate-colored mucus was accumulated in well-developed mastoid air cells, and glistening dotty cholesterol crystals were also found. In most cases, enlarged aditus, destruction of lateral attic wall, erosion of ossicular chain, exposure of horizontal segment of facial nerve and tegmen of attic were observed. Occlusion of Eustachian tube was noted in 6 cases, and occlusion of tympanic isthmus was revealed in all cases. A post-operative dry ear was achieved in all patients, and hearing improvement was achieved in all 12 cases following tympanoplasty. Cholesteatoma and cholesterol granuloma in middle ear may share a common pathophysiological etiology: occlusion of ventilation and disturbance of drainage. The diagnosis should be considered when patients presented with chronic otitis media with bloody otorrhea. CT and magnetic resonance imaging are useful for the diagnosis before operation. The surgical approach depends on the location, extension and severity of the lesion. The purpose of surgery is to remove the lesion and create an adequate drainage.

Objective To explore the double-labeling method of monitoring the GHRP regulatory function on [Ca2+]i and NO in cardiomyocytes of rats on real time under LSCM.Methods The reformed constant-flow Langendorff system and enzyme-dissociated was used to isolate cardiomyocytes.[Ca2+]i and NO in the cardiomyocytes of SD rats were double-labeled by their molecular probe Rhod-2/AM and DAF-FM/DA,respectively to monitor the regulatory function of GHRP on [Ca2+]i and NO on real time by LSCM.Results Ca2+ signal showed a red fluorescence and NO showed a green fluorescence while the overlapping of the two signals showed a yellow-green fluorescence by this system,and the similar effect presents in both double-labeled state and the single labeled one:GHRP induced a transient[Ca2+]i increase then followed by a plateau phase while there was not significant change in NO signal system after GHRP stimulation under the LSCM in the cardiomyocytes of rats.Conclusions After having established the double-labeling method we monitored the GHRP regulatory function on [Ca2+]i and NO on real time in cardiomyocytes of rats under LSCM causing the [Ca2+]i biphasic increase while no significant change in NO signal system.

30nm) accounted for 3.5% of these contacts. The mean maximum diameter of the vesicles was 49.4 nm, the volume density was 0.023 and profile density was 36. The distribution of the vesicles was as following: 29.1% opened onto or touched the abluminal membrane, 44,9% without visible connection to either surfaces, 26% opened onto or touched the luminal membrane. It was concluded that the mechanism of lymph formation in the stomach seems to be different from that of those organs such as heart, liver, kidney and thyroid. The present study suggested that the intercellular pathway may act as the primary route for lymph formation and macromolecule transportation, and the intracytoplasmic vesicular system may also play certain role in the transport of macromolecules.

Objective To compare the effects of heat-sensitive moxibustion and ginger-partition moxibustion on refractory peripheral facial paralysis. Methods Fifty-five patients with refractory peripheral facial paralysis were randomized into heat-sensitive moxibustion group (N=28) and ginger-partition moxibustion group (N=27). For two cases dropped out during the treatment, a total of 25 cases were finally enrolled into the ginger-partition moxibustion group. Two groups received oral use of mecobalamin tablets and conventional acupuncture, and heat-sensitive moxibustion group was given heat-sensitive moxibustion and ginger-partition moxibustion group was given ginger-partition moxibustion additionally. The moxibustion was performed once a day and ten times constituted one course, the treatment covered 6 courses. The clinical effect of the two groups was evaluated by 40-score method, House-Brackmann facial neurological function evaluation standard, blink reflex ( BR) , electromyogram and electroneurography. Results ( 1) Symptoms integral was increased in both groups after treatment ( P<0.01) , and the scores of heat-sensitive moxibustion group were higher than those of ginger-partition moxibustion group ( P<0.01). ( 2) The markedly effective rate of heat-sensitive moxibustion group was 75.00% and that of ginger-partition moxibustion group was 44.00%, and there was statistically significant difference between them ( P<0.05). ( 3) The results of electrophysiological examination showed that the difference values of ipsilateral and contralateral BR R1, R2, R2’ in both groups after treatment were less than those before treatment ( P<0.01) , and the abnormal rate of electromyography for heat-sensitive moxibustion group was improved obviously after treatment ( P<0.01) . The amplitude of compound muscle action potentials ( CMAP) of orbicularis oculi/orbicularis oris at the affected side of both groups showed a decreasing trend, but the differences were insignificant between the two groups after treatment ( P>0.05). Conclusion The curative effect of heat-sensitive moxibustion for the treatment of refractory peripheral facial paralysis is better than that of ginger-partition moxibustion.

By using 5'-nucleotidase-alkaline phosphatase (5'-Nase-AlPase) double staining method, the fine distribution of the lymph vessels in the stomach wall of the rabbit, guinea pig and rat has been observed. Under light microscope lymph capillaries showed strongly 5'-Nase positive reaction with brown or dark brown staining. However blood capillaries revealed significantly A1Pase activity with blue staining. The lymph capillaries were seen in all layers of the stomach wall in three species, but the lymph vessels were only shown in the submucosa, muscularis and serosa. In the mucosa lymph capillaries could be found in the deep layer of the lamina propria. In the submucosa there were lymph vessels and capillaries. In the muscularis lymph capillaries and vessels not only could be found between oblique and circular muscle or between circular and longitudinal muscle, but also among muscle fiber bundles of each layer. In the serosa there were larger lymph vessels situated near the muscularis. The observation on semithin and ultrathin sections also shown the similarity in the lymph vessels distribution. There was no difference in the distribution of lymph vessels in the stomach wall between rabbit, guinea pig and rat.
