Objective To use peer education to guide community diabetic patients to adopt diet therapy using food exchange method in order to explore effective method for diet therapy of diabetes mellitus. Meth-ods 91 diabetic patients were selected using simple sampling method and randomly divided into the peer ed-ucation(45 cases) and the common education group(46 cases), the two groups adopted food exchange method for diet therapy for 1 year. The blood glucose, blood lipid, glycosylated hemoglobin and body weight index were compared between the two groups using t test. Results The blood glucose, blood lipid, glycosylated hemoglobin and body weight index all decreased in the two groups after intervention, but the the decreased de-gree in the peer education group was more obvious. The fasting blood glucose, 2 hour postprandial blood glu-cose, glycosylated hemoglobin, triglyceride, low-donordensity lipid protein and body weight index in the peer education were lower thanthose of the common education group, but HDL-C was higher. Conclusions Peer education is more effective in health education of food exchange method.

OBJECTIVE:
To investigate the pure tone audiometry characteristics and curative effect in sudden hearing loss patients with hypertension.
METHOD:
One hundred and fifty-seven inpatients (168 ears) with hypertension suffered from sudden hearing loss were included in this study. We retrospectively analyzed the audiological index of these patients by comparing the pure tone audiometry (PTA) among patients in the aspects of gender, age, affected side, duration of hypertension, with or without inducement, concomitant symptoms and other combined diseases. The hearing threshold at different frequency was also compared, as well as the curative effect among patients with diverse audiological characteristics.
RESULT:
Of the contemporaneous sudden hearing loss patients (874 cases), the prevalence of hypertension was 17.96%, where the male ones accounted for. 28.69% (103/359) and the female ones accounted for 19.42% (54/278) respectively with statistically significant difference between genders (P < 0.01). The prevalence of hypertension in 34-44 years old group, 45-49 years old group, 60-69 years old group and over 70 years old group was 12.69% (25/197), 22.51% (70/311), 47.62% (40/84), 48.89% (22/45) respectively, which were statistically different (P < 0.01). The number of impaired ears with audiogram configuration characterized by rise type, downslope type, flat type and completely deafness type was 18 (10.71%), 61 (36.31%), 41 (24.40%), and 48 (28.57%), respectively. The decrease of hearing threshold in PTA were increasingly severe as the increasing impaired-frequency, and the difference of the degree of hearing impairment among these three types of frequencies was statistically significant (P < 0.01). The hearing threshold means of each frequency had no significant difference among patients with various gender, age and Cardiovascular Risk Stratification (P > 0.05). The hearing threshold means of each frequency of unilateral hearing loss patients was significantly higher than that of bilateral hearing loss patients (P < 0.05). The hearing threshold means at 125 Hz, 250 Hz, 500 Hz and 1 kHz showed significant difference among patients with different duration of hypertension (P < 0.05). The total effective rate of sudden hearing loss in patients with hypertension was significantly lower than that in the sudden hearing loss patients without hypertension (19.64%, 61.57% respectively, P < 0.01). The total effective rate presented significant difference among patients with different duration of hypertension and different Cardiovascular Risk Stratification (P < 0.05).
CONCLUSION
The prevalence of sudden hearing loss in hypertension patients was higher in male than in female, which rose with age and combined disease. The hearing threshold means at mid-frequency and high-frequency were higher than that at low-frequency. The total effective rate of sudden hearing loss was relatively low in patients with hypertension. The longer the duration of hypertension and the higher the Cardiovascular Risk Stratification, the lower the total effective rate. Comprehensive understanding of audiological characteristics and hypertension condition plays a crucial role in type-specific treatment of sudden hearing loss.

OBJECTIVETo investigate the protect effects of sodium ferulate (SF) on the daunormbicin(DNR-induced cardiotoxicity in juvenile rats.
METHODSForty male juvenile SD rats were randomly divided into control group (Control), daunorubicin group (DNR), sodium ferudate treatment group (DNR + SF), sodium ferudate group (SF) (n = 10) . Juvenile rats were intraperitoneally treated with DNR (2.5 mg/kg every week for a cumulative dose of 10 mg/kg) preparation immature myocardial injury model in presence with SF (60 mg/kg) oral treat- ment for 25 days. The left ventricular pressure and its response to isoproterenol were measured using left ventricular catheter. Rat myocardium myocardial pathology specimens and ultrastructure changes were also observed. The expression of cardiac Troponin I (cTNI) was detected by Western blot and RT-PCR. Results: SF treatment could inhibit the decreasing of heart rates induced by DNR damage (P < 0.05); it could increase the left ventrivular end diastolic pressure(LVEDP), heart rate, the maximal left ventrivular systolic speed(LVP + dp/dtmax) and the maximal left ventrivular diastolic speed (LVP-dp/dtmax) responding to isoproterenol stimulation(P < 0.01); SF also could improve the myocardial ultrastructure injuries and inhibit the decreasing of cTNI expression caused by DNR damages (P < 0.05).
CONCLUSIONSF treatment could alleviate the decreasing of cardiac reservation induced by DNR damages in juvenile rats, which might be related to its reversing the effects on the cardiac systolic and diastolic function injuries and its inhibiting effects on the decreasing of cTNI expression caused by DNR. The mechanism of SF preventing daunorubicin-induced cardiotoxicity in juvenile rats is relevant to inhabited cardiac Troponin I expression.

Objective To investigate the preliminary value of mitral annular displacement (MAD) with two-dimensional speckle tracking in evaluating left ventricular systolic function. Methods Forty-nine patients with dilated cardiomyopathy, aged 51±14 years (DCM group), and 43 age-matched (46±14 years) normal subjects (control group) were enrolled in this study. Two-dimensional and real-time three-dimensional (RT3D) imaging were obtained all at the apical four-chamber view. The parameters of MAD and RT3D-LVEF were obtained using off-line QLAB software. Results Compared with control group, MAD reduced significantly in DCM group (P<0.01). The parameters of MAD correlated positively with LVEF (P<0.01). The intra- and inter-observer variabilities for measurement of MAD were low. When one point was placed at the chest wall, the ratio of long axis shortening correlated best with LVEF among all the data of MAD. Conclusion Based on two-dimensional speckle tracking imaging, MAD is a rapid and reproducible method of determining LV global systolic function, may even replace LVEF in the future.

BACKGROUND:The therapeutic effects of donkey-hide glue reinforcing bone oral solution on osteoporosis have been determined, but the exact effective mechanism is to be approached. OBJECTIVE: To investigate the effects of donkey-hide glue reinforcing bone oral solution (DGRBOS) medicated serum on osteoprotegerin (OPG)and its ligand(OPGL)mRNAexpression of osteoblast in fetal rats and explore the molecular mechanism of treating osteoporosis with DGRBOS. DESIGN: A randomized controlled trial. MATERIALS: The experiment was carried out from June 2003 to October 2004 in Bone Metabolic Laboratory of Department of Integrative Chinese and Western Medicine, Affiliated Hospital of Tongji Medical College,Huazhong University of Technology and Science. Totally 30 3-month-oldWistar rats (15 males and 15 females) were randomly divided into 3 groups, I.e. DGRBOS group, estrogen group and control group, with 10 rats in every group. 12 clean newborn SD rats were selected to isolate and cul ture osteoblast. METHODS: ①After intragastric administration for 7 days, medicated serum was prepared respectively from the three groups. ②Skull osteoblast isolated from newborn SD rats was made into single cell suspension, then after digestion and passage, the subcultured osteoblast cell was made into cell suspension. The cultured osteoblasts were divided into 5 groups and given equal volumes of drug liquor. The DGRBOS group was given DGRBOS-medicated serum at the concentration of 100, 500 and 1 000 g/L which was diluted by nutrient solution; the estrogen group was given tibolone-medicated serum of 100 and 1 000 g/L; the control group was givenonly culture fluid. Meanwhile every group was given calf serum (100 g/L) for further culture. ③The osteoblast proliferation was measured by antigenic MTT colorimetric analysis and 3H-TdR penetration method. The in tra-cellular BGP contents were evaluated by radioimmunity .The mRNA expression of OPG and RANKL in osteoblast was analyzed by Rt-PCR. ④ One-way analysis of variance was applied to compare data among groups. MAIN OUTCOME MEASURES: mRNA expression of OPG and PAN KL in osteoblasts from fetal rats after intervention by medicated serum ofDGRBOS or Livial. RESULTS: ①The osteoblast proliferation measured by antigenic MTT colorimetric analysis and 3H-TdR penetration method showed that the proliferation in the DGRBOS group and tibolone group was enhanced moresignificantly than that in the control group (P < 0.05-0.01), and reached maximal effect at the concentration of 500 g/L (P < 0.01), but when the concentration was over 500 g/L, the effect tended to saturate. The medicated serum with all concentrations from DGRBOS and estrogen groups could increase the contents of BGP in osteoblasts (P < 0.05). ②The mRNA expression of OPG reached the peak when the DGRBOS medicated serum was 1 000 g/L, and was obviously higher than that at the concentration of 100 and 500 g/L (P < 0.05). The expression in DGRBOS group at the concentration of 1 000 g/L and in the estrogen group at the concentration of 100 and 1 000 g/L was apparently higher than that of the control group (P < 0.01). ③The mRNAexpression of RANKL was the highest in DGR BOS group with 1 000 g/L concentration, and was markedly lower than that of the concentration of 100 and 500 g/L (P < 0.05). The expression in DGRBOS group at the concentration of 1 000 g/L and in the estrogen group at the concentration of 100 and 1 000 g/L was noticeably lower than that in the control group (P < 0.01).CONCLUSION: ①The DGRBOS could remarkably enhance osteoblast proliferation in dose-dependent and a dose-saturable manner, and the effect was close to that of tibolone. ②Partial mechanism of DGRBOS in treating osteoporosis might be promoting osteoblast proliferation and regulating OPG/RANKL expression.
