Objective To investigate the prevalence of renal insufficiency and its associated factors in type 2 diabetes mellitus with normoalbuminuria using estimated glomerular filtration rate ( eGFR) .Methods We retrospectively analyzed 10-year data of chronic complications in type 2 diabetics in-patient from the Chinese Diabetes Society.eGFR was estimated using the equation from Modification of Diet in Renal Disease(MDRD) study.The clinical characteristics as well as associated factors for low eGFR were analyzed among the normoalbuminuric type 2 diabetic patients.Results A total of 1351 type 2 diabetic patients were included, 755 patients with normoalbuminuria, 466 patients with microalbuminuria and 130 patients with macroalbuminuria respectively.Among the patients, 310 (22.9% ) had low eGFR (GFR <60 ml · min~(-1) · 1.73 m~(-2) ) , 19.7% (149/755) in the patients with normoalbuminuria, 21.9% (102/466) in microalbuminuria and 45.4% ( 59/130 ) in macroalbuminuria Patients with normoalbuminuria and low eGFR suffered more chronic complications than those with normoalbuminuria and normal eGFR, mainly retinopathy, cerebrovascular diseases and sensory neuropathy.Stepwise logistic regression analysis revealed that age ( OR = 1.042, P < 0.001), diabetic duration ( OR = 1.038, P = 0.045), systolic blood pressure (OR = 1.017, P < 0.001) were independently associated with renal impairment among the patients with normoalbuminuria.Body mass index ( OR = 0.868, P < 0.001) and HbAlc (OR =0.898, P =0.021) were also related with renal insufficiency.Conclusion A considerable proportion in type 2 diabetic patients without albuminuria may exist renal impairment, and eGFR estimation could benefit the evaluation of renal function in such patients.

Objective To analyze the effects and experience of ideological and political education through inquiring students' satisfaction on it,and to strengthen innovation and efficiency. Methods Five hundred and fifty university students were chosen by random.Through anonymous questionnaires,information on attention and satisfaction of ideological and political education about educate by all staff,campus culture,psychological status,and extracurricular activities were acquired.Results More than 56% of the students thought who impressed them most were the professional teachers;and 75.64% of them would ask friends for help when they were facing difficulties.And 44.91% considered study as the main resource of pressure,although the other 39.09% chose the career perspective.Then,57.45% were willing to take part in the meaningful activities after class,though the study was tough.And 45.45% hoped it would be a great progress on extracurricular activities;74% would take part in entertainment,and on the other hand 68.55% chose volunteer;and 87.72% interested in learning psychological knowledge. Conclusion It is important to strengthen and develop ideological and political education among students in the university.And attention should be paid to the innovation and efficiency of the education.

BACKGROUND: The c-fos gene is commonly expressed in neurons,which may act as one of the signs of activities and reflection of injured neural cells.OBJECTIVE: To investigate the expression of hippocampal c-fos gene of rats with ischemic cerebral injury and the protective role of shenmai injection at the molecular level.DESIGN: Randomized controlled study.SETTING: Department of Histology and Embryology, Luzhou Medical College.MATERIALS: The experiment was completed at the Department of Histology and Embryology, Luzhou Medical College from January to March 2002. Totally 30 male Wistar rats were randomly divided into control group, ischemia group and treatment group with 10 in each group.METHODS: Bilateral common carotid arteries of rats in the ischemia and treatment groups were splinted for 30 minutes and reperfused for 1 hour to establish models of ischemic cerebral injury. Rats in the treatment group were injected with 2 mL/kg of shenmai (constituted with hongshen, dwarf lilyturf tuber and other Chinese herbal medicines) 30 minutes before ischemia. Rats in the ischemia group were not treated with any drugs, and rats in the control group were treated with sham operation but without splinting common carotid artery and giving any drugs. Hippocampal tissue of rats was obtained to make paraffin sections. In every group, one section from each rat was taken at random. Totally 100 neurons of every group were counted. Expression of c-fos gene in hippocampal neuron was observed according to the nuclear color of neurons (+++ as dark-brown mark;++ as brown mark; + as light brown mark; - as no brown mark).MAIN OUTCOME MEASURE: c-fos expression of hippocampal neurons of rats in each group.RESULTS: Totally 30 rats entered the final analysis. Expression of c-fos gene in hippocampal neurons was significantly more in the ischemia group than that in the control group (+++: 24/visions, 7/visions, P ＜ 0.05); but that in the treatment group was less than that in the ischemia group (+++:13/visions, 24/visions, P ＜ 0.05).CONCLUSION: Shenmai injection can reduce the expression of c-fos gene in hippocampal neurons of rats with ischemic cerebral injury, and can protect neural cells of ischemic cerebral injured tissue.

Objective To detect the serum prohibitin protein(PHB)level in children with renal interstitial damage and analyze the correlation between PHB and renal interstitial fibrosis(RIF). Methods Serum PHB protein levels were determined by Western blot analysis in 36 children with kidney diseases,and 30 healthy children were studied as control. Levels of BUN,Scr,and urinary microprotein series(including ALBU/Cr,NAGU/Cr,IgG U/Cr,α1-MU/Cr)were studied by automatic biochemical analyzer. Renal interstitial damage was semiquantitatively graded according to Katafuchi's method. The correlation between serum levels of serum PHB protein and those of BUN,Scr as well as urine microprotein were analyzed. Results Serum PHB protein was positive in children with diverse kidney diseases however it was negative in the normal controls(P ＜ 0.05). Serum PHB levels were significantly higher in children with proliferative glomerulonephritis than those with non-proliferative glomerulonephritis(P ＜ 0.05). Statistical analysis indicated that serum PHB levels positively correlated with the degree of tubulointerstitial lesions(r ＝ 0.868,P ＜ 0.001)as well as the glomerular injuries(r ＝ 0.753,P ＜ 0.001). And,serum PHB levels were also positively correlated with urinary microprotein including NAG(r ＝ 0.586,P ＜ 0.001)and IgG(r ＝ 0.341,P ＜ 0.001). Conclusions Serum PHB levels were significantly increased in children with kidney diseases and were positively correlated with the degrees of renal interstitial damage,suggesting that PHB might be a potential clinical marker for detecting tubulointerstitial lesions.

Objective To observe the clinical effect on cervicogenic headache (CEH) of pulsed radiofrequency stimulation (PRF) applied to the C2 dorsal root ganglion combined with nerve block.Methods A total of 78 cases diagnosed as CEH were randomly divided into a combined treatment group,a PRF treatment group and a nerve block group.The combined treatment group was given both PRF applied to the C2 dorsal root ganglion and blocking therapy.The other two groups were given only one treatment or the other.All the treatments were once weekly for 3 weeks.Before treatment and 1,3 and 6 months after treatment,all of the patients' headaches were evaluated using a visual analogue scale (VAS).Results At 1,3 and 6 months after treatment,the average VAS scores of all three groups had decreased significantly.The VAS ratings dropped the most in the combined treatment group,followed by the PRF group and then the nerve block group.All the intergroup differences were statistically significant.The combined treatment group's cure rate (88％) was significantly better than that of the PRF group (81％),which was significantly better than that of the nerve block group (54％).Conclusion Combining PRF applied to the C2dorsal root ganglion with nerve block therapy has a synergistic effect on CEH.The curative effect of the combined treatment was better than either PRF or blocking alone.
