Objective To investigate interventions of vitamin E( VE) on indomethacin-induced gastric mucosal injury. Methods Fifty mice were randomly divided into 5 groups. Normal control group was administrated with saline, others were intragastrically administrated with indomethacin ( 20 mg · kg-1 ) . After 4 hours, mice were intragastrically treated with saline, cimetidine(200 mg·kg-1),VE(25,50 mg·kg-1) once a day for 5 consecutive days. By the end of the treatment,gastric mucosa injury index,serum superoxide dismutase(SOD) activity,and malondialdehyde(MDA) content were determined. ResultsGastric mucosal injury indexs of mice treated with cimetidine,VE at low and high doses were significantly lower than that of the model control and higher than that of the normal control(P<0. 01). VE at high doses showed significantly less mucosal injury than that of the cimetidine group(P<0. 05). Healing-rate of gastric mucosal injury in cimetidine group,VE low-dose and high-dose groups were significantly higher than that of model control group(P<0. 01). SOD activity of VE at low and high doses was significantly lower than that of the model control and cimetidine groups(P<0. 05). The results also revealed that cimetidine and two doses of VE significantly elevated SOD activity and lowered the level of MDA(P<0. 05, 0. 01). Conclusion VE can obviously promote the healing of gastric mucosal injury,especially at high dose,which is better than cimetidine,while,the low dose is comparable with cimetidine.

OBJECTIVE:
Mutations in the GJB2 are the most common cause of nonsyndromic autosomal recessive sensorineural hearing loss. A few mutations in GJB2 have also been reported to cause dominant nonsyndromic or syndromic hearing loss. This study analysised the GJB2 dominant mutation in Chinese deafness.
METHOD:
1641 patients as GJB2-related hearing loss were enrolled, summarized the type of dominant mutaion, analyzed the hearing level and other systerm lesion.
RESULT:
Nine probands with severe-profound hearing loss were diagnosed as GJB2 domiant mutation (R75W,G130V, R143Q,p. R184Q). And one patient with R75W mutation was diagosed as hearing loss and palmoplantar keratoderma.
CONCLUSION
GJB2 dominant mutation can cause severe-to-profound bilateral sensorineural hearing impairment and not common with syndromic hearing loss in Chinese deafness.

OBJECTIVE To explore the expression of Bcl-2, on mRNA and protein levels, in the different age of C57BL/6 mice cochleae and the expression localization in the cochleae.METHODS Using ABR to test the hearing level in C57BL/6 mice. Surface preparation of cochlear basil membrane is used to observe the morphology and amout of the outer and inner hair cells in different age of C57BL/6 mice. Fluorescent quantitative real time PCR, immunofluorescence histochemical method and western blot are used to detect the expression of Bcl-2 on the mRNA and protein levels in the C57BL/6 mice cochlea of different age groups ('young group', 'elderly group').RESULTS ABR results showed that the hearing threshold of 'older' C57BL/6 mice is much higher than that in the 'young' mice, and surface preparation of cochlear basil membrane showed the hair cell localized in the cochlear basil turn of 'old' mice arranged in a disorder station and part of hair cells were lost. Also, the spiral ganglion cells arranged sparsely and messily. Fluorescence quantitative real-time PCR results suggest the expression of Bcl-2 on/at the mRNA level of the 'old' mice cochleae decreases significantly, compared to that in the 'young' mice. The results of Immunofluorescence and Western blot suggest the expression of Bcl-2 on/at the protein levels of the 'old' mice cochlea decreased, compared to that in the 'young' mice. Also, the Bcl-2 is located in the cytoplasm, and the expression of Bcl-2 in the inner hair cells seems higher than that in the outer hair cells. CONCLUSION The expression of Bcl-2 significantly deceased in the 'old' C57BL/6 mice cochleae, both on mRNA and protein level, which may be related to the hearing loss and loss of hair cells.

Objective:To investigate the relation among platelet activation marker(GPⅡb/Ⅲa,CD62p) and amounts of fibrinogen (FG) and of D-dimer (DD) in elderly patients with chronic cor pulmonale exacerbation.Methods:Subjects were divided into four groups (42 elderly patients with chronic cor pulmonale exacerbation,42 elderly patients with chronic cor pulmonale remission stage,30cases of healthy elderly controls and 30 cases of healthy non-elderly controls).Positive rates of GPⅡb/Ⅲa and CD62p were measured with tricolor flow cytometry.We also determined FG and DD in patients with chronic cor pulmonale and in normal controls.Results:Compared with those of chronic cor pulmonale remission stage group,healthy elderly group and healthy non-elderly group,the levels of GPⅡb/Ⅲa,CD62p,FG and DD increased significantly in elderly patients with chronic cor pulmonale exacerbation (all P<0.001).There was a positive correlation between the amount of GPⅡb/Ⅲa or CD62p and the amount of FG and DD in elderly patients with chronic cor pulmonale exacerbation.Conclusion:There is increased coagulation and platelet activity in elderly patients with chronic cor pulmonale exacerbation,and there is a significant correlation between platelet activity and hypercoagulability.

Objective To calculate the residoal liver volume using a virtaal liver surgery planning system,and to investigate the value of standardized estimated liver remnant volume ratio (STELR) in prcdicting hepatic dysfunction after hepatectomy.MethodsThe clinical data of 76 patients with primary liver cancer who were admitted to the First Affiliated Hospital of Fujian Medical University from April 2007 to October 2011 were retrospectivcly analyzed.The virtual resection and residual liver volume measurements were carried out using Liv 1.0 software.The value of STELR in predicting hepatic dysfunction was assessed using receiver operator characteristic (ROC) curves.Effects of different risk factors on postoperative hepatic dysfunction were analyzed using univariate analysis of variance and multivariate Logistic regression models. Results The mean residual liver volumes predicted by the software and resected during operation were (489 ± 206)ml and (459 ± 199 )ml,respectively,with a positive correlation between predicted and actual resection volumes (r =0.916,P < 0.05).Of the 76 patients,48 had mild hepatic dysfunction,19 had moderate hepatic dysfunction and 9 had severe hepatic dysfunction.A critical STELR of 53% was associated with severe hepatic dysfunction.Severe hepatic dysfunction was detected in 2 out of 59 (3%) patients with STELR ≥ 53% and 7 out of 17 (41%) patients with STELR < 53%,which represented a significant difference ( x2 =5.085,P < 0.05 ).The result of univariate analysis revealed that STEL,R,operating time,intraoperative blood loss were significant prognostic indicators for severe hepatic dysfunction ( F =7.227,8.630,13.809,P <0.05).Multivariate Logistic regession revealed that STELR was a significant independent predictor of severe hepatic dysfunction ( Wald =6.675,P < 0.05 ).Conclusion The likelihood of severe hepatic dysfunction after hepatectomy can be predicted by STELR.

Objective To investigate the relationship of sperm morphology with seminal plasma zinc and sperm acrosin activity in male infertile patients.Methods 455 patients with male infertility were divided into 5 groups and 8 groups according to age and sperm morphology respectively.The sperm morphology,seminal plasma zinc and sperm acrosin activity were detected by the Diff-Quik stain,modified 5-Br-PAPS and modified Kennedy methods respectively.Results The percentages of morphologically normal sperm and seminal plasma zinc concentration in the infertile men groups were not different in various age groups(P >0.05 ).The sperm acrosin activity in the age group of 36-50 years was remarkably decreased (P <0.05),while which in other age groups had no statistical difference(P >0.05).Seminal plasma zinc concentration in the infertile men groups were not different in the 8 groups (P >0.05 ).Sperm acrosin activity was decreased with the percentage decrease of morphologically normal sperm (r =0.93,P <0.01).Conclusion The percentage of morphologically normal sperm is not affectd by the age and the seminal plasma zinc,which is positively correlated with the sperm acrosin activity.
