Objective Spermatogonial stem cells(SSCs)dissociated from 2~5 days postpartum mice were cultured on Sertoli cells feeders,to study the effect of Sertoli cells feeders on culture of mouse spermatogonial stem cells.Methods Specific markers CD9 of mouse SSCs cultured serum-free StemPro-34 SFM culture medium were identified by immunohistochemical assay.Result During the first week of culture,on Sertoli cells feeders or STO feeders,the biologica1 behaviors of spermatogonial stem cells showed no obvious difference.After a week of culture,compared with control,there were more number of spermatogonial stem cells remained when they were cultured for 60 days.These cells were expressed CD9 positive.In conclusion Sertoli cells can be used as feeders not only to promote survival but also renewal of spermatogonial stem cells.

Objective To investigate the effectivity of bispectral index(BIS)and auditory -evoked potentials index(AEP index)in monitoring the depth of desflurane anesthesia in the elderly. Methods Sixty patients(ASA gradeⅠ~Ⅱ)without obvious auditory and psychiatric dysfunction undergoing general anesthesia were enrolled in this study,and they were devided into the elderly group (n=30)and the non-elderly group(n=30)according to the age.After the endotracheal intubation,the lungs were ventilated with desflurane in oxygen.End-tidal concentrations of desflurane were maintained at 0.6,1.0 minimum alveolar concentrations(MAC)and 1.3 MAC for 20 minutes, respectively.The changes of BIS,AEP index,mean arterial blood pressure(MAP)and heart rate (HR)were recorded simultaneously.Results In the elderly and non-elderly groups,BIS were 94.14?6.5 and 94.5?4.6(P>0.05),and AEP index at pre-anesthesia were 87.2?11.7 and 89.2?6.9(P>0.05)respectively,which showed no statistic difference between two groups.BIS and AEP index decreased significantly in each time point at pre-anesthesia compared with those during anesthesia in two groups (P<0.05).In the periods of increasing concentration of desflurane,BIS decreased gradually in two groups(P>0.05),but BIS in the elderly group were higher than in the non-elderly group at the same end-tidal desflurane concentration(P>0.05),and BIS negatively correlated with the end-tidal desflurane concentration in two groups.In the elderly group,AEP index decreased significantly at the concentration of 1.0 MAC and 1.3 MAC of desflurane compared with that of 0.6 MAC(P<0.05),but there was no difference in AEP index with increasing end-tidal desflurane concentration from 1.0 MAC to 1.3 MAC(P>0.05).At every concentration of desflurane,AEPindexintheelderlygroupwaslessthaninthenon-elderlygroup(P<0.05).Conclusions BIS and AEP indexes correlate well with the end-tidal desflurane concentration,and are valuable for monitoring the depth of desflurane anesthesia in the elderly.AEP index can predict the difference in depth of anesthesia at the same end-tidal desflurane concentration between the elderly and the non-elderly.

Objective To investigate the chronic angio-complications of diabetes mellitus(DM)and impared glucosetolerance(IGT)patients were diagnosticated newly.Methods 46 patients with diabetes mellitus and 97 pa- tients of impared glucosetolerance were chosen in the study,and 35 patients were chosen as normal glucose tlerance group.Some biochemical criterion,carotid artery intima-media thickness and plaque condition were measure.Results The group of IGT contract coronary heart disease is 62.9 %,cetebrovascular disease is 20.6%,carotid artery atheromatosis is 50.5 %,the group of DM contract coronary heart disease is 65.2%,cerbrovascular disease is 26,1%,carotid artery atheromatosis is 69.6%,it have statistics significance compared with control group(P

Objectives By measuring left ventricular diastolic function and arterial stiffness,this study aims to probe into the effect of diabetes mellitus(DM) on left ventricular diastolic function and arterial stiffness,and evaluate the correlation between left ventricular diastolic funotion and arterial stiffness.Methods Seventy-six inpatients were enrolled.According to their coronary angiography,OGTF test results and past history of DM,patients were divided into controlled,CHD(coronary heart disease with no DM),and CHD+DM groups.Through invasive hemodynamic monitoring during left ventricular angiography,left ventricular end-diastolic pressure(LVEDP)and tan index were collected.Carotid-femoral pulse wave velocity(c-f PWV),reflected wave augmentation index (AIx@75) and other data reflecting the degree of arterial stiffness were collected bedside with non-invasive means.SPSS 18.0 was used for statistical analysis.Results No significant difference was found between groups for LVEDP,tau index,and AIx@75.In terms of c-f PMV,The CHD+DM group(8.79±1.59)cm/s differed significantly from the CHD group (7.43±1.42)cm/s and the controlled group(6.83±1.14)cm/s.No correlations were found between c-f PMV and LVEDP or tau index.A positive correlation was found between AIx@75 and tau index.Conclusions Compared with the controlled group and CHD patients with no DM,CHD+DM patients show worse arterial stiffness with no difference in ventricular diastolic function.There is a positive correlation between arterial stiffness and diastolic dysfunction.

The clinical data of 7 patients with porokeratosis (PK) were analyzed retrospectively.In 7 PK patients, 4 cases were disseminated superficial actinic porokeratosis (DSAP),1 case was disseminated superficial porokeratosis (DSP),1 case was giant porokeratosis (GP) and 1 case was hypertrophic porokeratosis (HP).The characteristic cutaneous manifestations were annular well-circumscribed keratotic plaques with slightly atrophic center and elevated border.All patients shared a common histological hallmark, the cornoid lamella.Four cases of DSAP patients had family medical history, consistent with autosomal dominant inheritance.DSP, GP and HP patients denied family medical history.Diagnosis of PK should be based on clinical manifestations, family medical history and histopathological examination.
