Objective To investigate the preference of the postgraduates in school for work and their psychological changes based on the analysis of the employment status of postgraduates majoring in clinical science of stomatology in Anhui medical university in recent five years in an aim to provide preemployment counseling.Methods The employment status of postgraduates majoring in clinical science of stomatology in affiiated stomatological hospital of Anhui medical university in recent five years (2006 -2010) was summed up.Questionnaire of employment preference and the psychological pressure was conducted in 66 postgraduates majoring in clinical science of stomatology (2008 -2010 grade).Results The employment rate of provincial first-class hospitals was obviously decreased in the recent five years while that of municipal first-class hospitals was increased gradually.The number of postgraduates willing to work in the municipal first-class hospitals was reduced while that willing to future their study and work in the non first-class hospitals was increased.Psychological pressure was univcrsally existed in students and did not get released.Conelusion As the employment situation for postgraduates majoring in clinical science of stomatology changes,the preference for work and psychological pressure of the postgraduates also undergo corresponding changes.Targeted measures can be formulated to work out the problem based on the understanding of these changes.Meanwhile,adjustment should be made in the training methods and employment guidance for postgraduates majoring in clinieal science of stomatology.

Objective To detect the levels of transforming growth factor-?_1(TGF-?_1) in plasma,serum and urinary of children with Immunoglobulin A glomerulonephritis(IgAGN) and mesangial proliferate glomerulonephritis(MsPGN) and explore the different effects of TGF-?_1 in the two diseases.Methods The plasma,serum and urinary TGF-?_1 levels were measured in 24 children with IgAGN,and 30 children with MsPGN and 30 healthy controls by enzyme-linked immunosorbent assay(ELISA).Results The TGF-?_1 levels in plasma,serum and urinary samples of IgAGN group were increased.The TGF-?_1 levels of IgAGN were significantly higher than those of MsPGN and heathy controls(P(0.05)).Conclusion It is showed that TGF-?_1 plays a diffenent role in IgAGN and MsPGN.

Objective To detect the level of serum cystatin C(CysC),macrophage migration inhibitory factor(MIF),urinary podocytes(UPC) and explore the correlation between the levels of the three and therapeutic effect in children with primary nephrotic syndrome(PNS).Methods The serum CysC,MIF levels were detected in 38 children with PNS,which were treated before and after remission by double-antibody sandwich sensitive enzyme-linked immunosorbent assay(ELISA).Podocyte-specific marker protein-Podocalyxin(PCX) was detected by immunofluorescene to definite UPC before and after remission and compare with those of healthy control group(n=15).Results Compared with control group,the levels of serum MIF were significantly increased in 22 patients responded sensitively to prednisone prior and post treatment(Pa0.05),however,CysC,MIF and UPC significantly increased after treatment in 16 steroid-resistant children(Pa0.05), MIF significantly decreased(Pa0.05)in steroid-resistant children after treatment.In 16 children with steroid-resistant, complete remission of PNS as cyclophosphamide pulse treatment being added in 10 patients,which CysC, MIF,UPC were significantly higher than those in control group(Pa

Objective To explore the expression of vascular endothelial growth factor(VEGF) and macrophage migration inhibitory factor(MIF) in kidney of diabetic rats,the influence of protein kinase C ? inhibitor LY333531 on the expression of VEGF and MIF.Methods Thirty wistar rats were divided at random into three groups:normal control group(NC group);diabetic model group(DM group),the rats models of diabetic mellitus were induced by streptozotocin(SIZ);LY333531 treated group(LT group),which were given LY333531 [10 mg/(kg?d)] by gastric perfusion after DM model inducing success.At the 10th week,the levels of blood glucose(BG),24 hours urine albumin excretion rate(AER),urine VEGF,and MIF were detected using enzyme-linked immunosorbent assay(ELISA).Glomerular cellularity and extracellular matrix(ECM) were observed by light microscope.The expression levels of VEGF and MIF in the kidney tissues in three groups of rats were detected using immunohistochemistry.Results BG,AER,VEGF,MIF in DM group were significantly higher than those in control group(Pa0.05).There was strongly stained of VEGF,MIF in glomerular mesangium in DM group,weakly positive in LT group by immunohistochemistry.The expression of VEGF and MIF in DM gorup significantly increased than those in NC group(P0.05).Conclusions The expression levels of VEGF and MIF in kidney tisues of diabetic rats significantly increase and correlation with the degree of renal tissue injury.LY333531 can contribute to cut down BG,decrease AER,VEGF,MIF excrection in urine,inhibit glomerular cellularity and ECM proliferation,inhibit expressions of VEGF and MIF to protect kidney.

Objective To explore the effect of 1,25-(OH)2D3 on Nephrin protein expression in renal of diabetic rats.Methods Diabetic rats were induced by streptozotocin(STZ).Groups were divided as follows:diabetic group(DM group),1,25-(OH)2D3 treated group[1,25-(OH)2D3 group] and control group.At the 12th week,haematuria and proteinuria were determined and the kidneys were removed by histopathology,immunostaining,and the expression of Nephrin mRNA and protein in renal cortex were detected by reversed transcription-polymerase chain reaction(RT-PCR).Results Compared with control and 1,25-(OH)2D3 groups,urine erythrocyte and protein excretion and glomerlar cellularity in DM group statistically increased(P0.05).Conclusion The effect of 1,25-(OH)2D3 is in relieving haematuria and proteinuria and up-regulate the expression of nephrin mRNA and protein to protein kidney.

Objective:To explore the association between dopamine-β-hydroxylase (DβH), norepinephrine transporter (NET) gene polymorphisms and panic disorder(PD).Methods:The structured clinical interview for the diagnostic and statistical manual of mental disorders fourth edition (DSM-Ⅳ) axis Ⅰ disorders was administered by trained clinical psychiatrist, 139 patients with PD(PD group) and 196 healthy controls(control group) were enrolled in the study.Single nucleotide polymorphism(SNP) genotyping was performed using an improved multiplex ligation detection reaction technique.SPSS 16.0 and PLINK softwares were used to compare the allele frequency and genotype distribution.Results:(1)Compared with control group, PD group carried more G allele(76.3% vs 68.4%) and fewer A allele(23.7% vs 31.6%) in NET rs5569, and the difference was significant(χ 2=4.986, OR=0.67, 95% CI: 0.47-0.95, P<0.05). However, the correlation was no longer significant after adjusting for Bonferroni’s multiple testing( P>0.05). (2)The additive model of NET rs5569 showed a association with PD ( OR=0.68, 95% CI: 0.48-0.96, P<0.05). And the recessive model of DβH rs1611114 showed a association with PD( OR=0.42, 95% CI: 0.18-0.96, P<0.05). However, these correlations were no longer significant after adjusting for Bonferroni's multiple testing( P>0.05). (3)No matter allele or genotype, there were no significant differences in DβH (rs129882, rs1611114, rs1611115) and NET (rs2242446, rs28386840) gene polymorphisms between panic disorder group and control group(all P>0.05). Conclusion:The present study indicates that there is no significant association of DβH and NET gene polymorphisms with PD.

OBJECTIVE: To explore the impact of upper airway expansion surgery on the blood pressure of hypertension patients with upper airway obstruction. METHOD: Clinical data of 45 cases of hypertension patients with nasal obstruction who were underwent upper airway expansion surgery. The morning sitting blood pressure of patients were recorded. All of the patients were underwent nasal expansion surgery and 11 cases with obstructive sleep apnea hypopnea syndrome were combined with H-uvulopalatopharyngoplasty. RESULT: Blood pressure of all 45 cases were apparently reduced in 12 months after the operations [systolic blood pressure (157.38 +/- 15.15) mmHg to (132.18 +/- 8.43) mmHg, diastolic blood pressure (95.42 +/- 9.28) mmHg to (82.31 +/- 5.88)mmHg], in which 9 cases with type I hypertension were lowered to normal pressure. Results had statistical difference between pre-operation and post-operation (P < 0.01). CONCLUSION Upper airway expansion surgery (including nasal and pharynx cav ity) can help lower blood pressure of hypertensive patients with nasal obstruction. Post-operative results were better than H-uvulopalatopharyngoplasty only.
