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 demonstrate the validity of volumetric QCT and dual energy X-ray absorptiometry( DXA )in bone mineral density (BMD) measurement and compare the difference in discriminating osteoporotic postmenopansal women with and without vertebral fracture. Methods One hundred and eighteen postmenopausal women [ mean age (62. 1 ± 7.0) years ] who received thoracolumbar radiographic examination were enrolled and divided into four groups (normal, osteopenia, osteoporotic and osteoporotic fractured group) also based on their BMD value of lumbar vertebra(AP-SPINE) measured by DXA: >x- 1s,x- 1s-x-2s, 0. 05 ]. In osteoporotic groups, AP-SPINE was not correlated significantly with other variables except 3D-CORT ( R2 = 0. 189, P < 0. 01 ) ; parameters of App60,80,100,120 BV/TV% were correlated significantly with 3 D-TRAB (R2 = 0. 955, 0. 951,0. 941,0. 912, P < 0. 01, respectively) and 2 D-TRAB(R2 = 0.912, 0.910, 0.878, 0.821, P < 0.01, respectively). The precision of 3D-BMD measurement was between 0. 70%--2. 25%. Conclusions Parameters derived from 3D-vQCT technique can discriminate osteoporotic postmenopausal women with fractured vertebrae from those without fractured vertebrae, and have better the capability than DXA. Among them, 3D-INTGL was the best parameter for diagnosing serious osteoporosis. App BV/TV% could be used to reflect the lost of trabecular bone precisely and to clinically predict fracture risk.

Background It is well known that tissue factor (TF) is expressed in tumor cells and neovascular endothelial cells of tumor.It plays an important role in the formation of new blood vessels as well as the growth and metastasis of tumor.However,whether TF is expressed or not in choroidal melanoma(CM)is unclear.Objective This study is to investigate the expression of TF in a choroidal melanoma cell line and human choroidal melanoma.Methods The expression of TF was studied in the optimal choroidal melanoma-1 (OCM-1) cell line and ten specimens from CM patients using immunhistochemistry.Ten normal eye specimens from donators were used as controls.Results The TF protein was mainly expressed in the cytoplasm.It is over-expressed in OCM-1 cells with positive rate of 85.33±5.47%.Hyper-expression of TF also was found in human choroidal melanoma with a positive rate of 41.60±14.17%.The integrated optical density (IOD) of positive cells in CM was 33853.67±16445.30,and only 5.65±4.26% of positive cells was found in normal human choroidal tissue.The IOD of TF expression in normal human choroidal tissue was 426.43±316.62.Conclusion The overexpression of TF in CM cells may be a new immunotherapy target for CM treatment.

Objective To investigate the actual situation of implementation of the project to reduce water arsenic in endemic arsenic poisoning areas in Shanxi province,and to provide a scientific basis for prevention and control of the disease.Methods In June 2011,a questionnaire survey of 151 arsenic endemic villages was carried out in Shanxi province.The actual situation of implementation of the project to reduce water arsenic was investigated.Water samples were collected and arsenic level was determined by atomic fluorescence spectrometry.Results In the 151 arsenic poisoning villages 126 villages had changed the water,and the rate was 83.44％.In these villages,22 villages did not use the water improvement utilities properly.Of the 33 water improvement projects to reduce arsenic,23 operated normally.The projects covered 110 villages,beneficiary population of 97 920 people,accounting for 46.9％(97 920/208 736) of the total population.Water arsenic exceeded the national standards(≤0.05 mg/L) in 10 of the water improvement projects which covered 31 villages,including 15 nonendemic villages and 16 diseased villages.There were a population of 24 764 people in the diseased villages.Conclusions In Shanxi endemic arsenic poisoning areas,water improvement efforts need to be strengthened; the quality of water improvement project needs to be improved,and the project's later management and maintenance also need to be further strengthened.

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.

In order to identify Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix using ITS2 barcodes, genomic DNA from sixty samples was extracted and the ITS2 (internal transcribed spacer) regions were amplified and sequenced. The genetic distances were computed using MEGA 5.0 in accordance with the kimura 2-parameter (K2P) model and the neighbor-joining (NJ) phylogenetic tree was constructed. The results indicated that for Aucklandiae Radix (Aucklandia lappa), Vladimiriae Radix (Vladimiria souliei and V. souliei var. cinerea), Inulae Radix (Inula helenium), Aristolochiae Radix (Aristolochia debilis) and Kadsurae Radix (Kadsura longipedunculata), the intra-specific variation was smaller than inter-specific one. There are 162 variable sites among 272 bp after alignment of all ITS2 sequence haplotypes. For each species, the intra-specific genetic distances were also smaller than inter-specific one. Furthermore, the NJ tree strongly supported that Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix can be differentiated. At the same time, V. souliei (Dolomiaea souliei) and V. souliei var. cinerea( D. souliei var. cinerea) belonging to Vladimiriae Radix were clearly identified. In conclusion, ITS2 barcode could be used to identify Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix. Our study may provide a scientific foundation for clinical safe use of the traditional Chinese medicines.

To study the chemo-preventive effect of the supercritical extracts from Angelica sinensis (SFE-AS) on induced colorectal carcinoma in mice by using the AOM/DSS-induced male mice colorectal carcinoma model, and discuss its possible action mechanism. Male Balb/c mice were subcutaneously injected with single dose of azoxymethane (AOM, 10 mg x kg(-1) body weight). One week later, they were given 2% dextran sodium sulfate (DSS) in drinking water for 7 days to induce colorectal carcinoma. Each drug group was orally administered with supercritical extracts from Angelica sinensis at 15, 30, 60 mg x kg(-1) until the 17th week. The tumor incidence rate of the SFE-AS group, mice tumor-bearing quantity and tumor-bearing volume of the SFE-AS group were lower than that of the AOM/DSS model control group, which may be related with the significant reduction of PCNA, COX-2, iNOS in the AOM/DSS-induced mouse colorectal carcinoma model associated with inflammation by SFE-AS. According to the results of this study, SFE-AS showed an intervention effect in the incidence and development of AOM/DSS-induced mouse colorectal carcinoma associated with inflammation, and could be further used in chemo-preventive studies on human colorectal carcinoma.
