Objective To explore the value of characteristic manifestation of diffusion-weighted images at 3.0T MR system in cer-ebral disease.Methods 120 patients with cerebral disease diagnosed by MR diffusion-weighted images (fat suppression effect,T2 blackout effect,T2 shine-through effect,T2 washout effect)underwent routine MR scan,including echo planar imaging-diffusion weighted imaging (EPI-DWI)and apparent diffusion coefficient (ADC)map,whose characteristic manifestations of DWI were retro-spectively analyzed.Results 1 5 cases of lipoma and 8 cases without fat lesions were diagnosed with fat suppression effect.13 cases of acute cerebral hematoma,1 1 cases of hemorrhagic cerebral infarction and 1 6 cases of micro bleeding of missed diagnosis or small cavernous hemangioma were diagnosed with T2 blackout effect.1 5 cases of epidermoid cyst,5 cases of choroid plexus cyst were di-agnosed with T2 shine-through effect.1 5 cases of posterior reversible encephalopathy syndrome and 22 cases of brain tumor were di-agnosed with T2 washout effect.Conclusion Comprehensive use of the characteristic manifestation of EPI-DWI and ADC map can help the diagnosis of cerebral disease.

· AIM: To observe the effects of PTEN and the tumor suppressor gene in proliferative LECs of the rabbit.·METHODS:Forty-two white rabbits were randomly divided into test group (36 rabbits) and control group (6rabbits). The transparent lenses of treated rabbits were operated with extra capsular cortex extraction, and the controls were kept untouched. The rabbits were sacririced at 1d, 3d, 1wk, 2wK, 1mo and 2mo after surgery.Immunohistochemistry was applied to detect proliferative cellular nuclei antigen (PCNA) as well as hybridization in situ and reverse-transcriptase polymerase chain reactions (RT-PCR) were applied to detect phosphatase as well as tensin homology deleted on chromosome 10(PTEN) mRNA in lens equartor.·RESULTS:PCNA expression increased significantly to a high level at 1wk, began to reduce 2wk later, and recovered to the normal level 1 or 2mo after the surgery.PTEN mRNA expressed positively in normal rabbit LECs.The relative PTEN mRNA contents reduced greatly at 1dafter operation and remained low level at 3d. It began to increase slightly at 1wk, kept rising at 2wk and regained the normal expression after 1 or 2mo. There was inverse correlation between the PTEN mRNA and PCNA expression.·CONCLUSION: PTEN mRNA expresses positively in normal rabbit LECs plasma. PTEN participates in LECs proliferation and correlates with lens proliferative conditions.

OBJECTIVEThis longitudinal study aimed to investigate the caries status of primary and permanent teeth among 6-year-old children in Sichuan Province from 2010 to 2012.

METHODSA sample that comprised 652 6-year-old children from six different elementary schools (three represented the urban areas, and the other three represented the rural areas) were examined according to a baseline, with follow-up examinations at 1, 2, and 3 years. Eruption and caries experience were re- corded using World Health Organization criteria.

RESULTSThe prevalence rates of primary tooth caries of 6-year-old children in Sichuan Province for 3 years were 74.23% (484/652), 75.61% (493/652), and 81.90% (534/652). The filling rate of the primary teeth was 5.87% (145/2,471) in 2012, with significant differences (P < 0.01) between the urban areas [10.84% (133/ 1,227)] and rural areas [0.96% (12/1,244)]. The total pit and fissure rate of the first molar was 14.11% (92/652) in 2012, with significant differences between the two areas (P < 0.01) [rural: 0.66% (2/303); urban: 25.79% (90/349)].

CONCLUSIONThe pre- valence of caries in the primary and permanent teeth of 6-year-old children was high. An increasing prevalence tendency was observed as the age increased. The prevalence of first molar caries indicated that prevention and control of dental caries should be performed as early as possible.

Objective To give an empirical study on the interests claims of employees in public hospitals. Methods By questionnaire investigation, to sum up data using factor analysis and pairedsamples T test, and to compare difference between different kinds of patients using ANOVA. Results The interests claims of employees can be summed up to seven factors and there is some significant difference between different kinds of employees. Conclusion At current stage, public hospitals need pay more attention to material interests claims of employees.

Objective To retrospectively analyze the relationship of the classification and risk stratification in senile hypertension with benign prostatic byperplasia (BPH).Methods Totally 376 male senior patients,including 233 senile hypertensive patients and 143 non-hypertensive patients as a control,were enrolled in this study.There were 35 cases of hypertension at level 1,82 cases at level 2,116 cases at level 3.Based on risk stratification of hypertension,there were 3 cases of low-risk,28 cases of medium risk,75 cases of high-risk,127 cases of very high risk.All candidates accepted the International Prostatic Symptom Score (IPSS) assessment before the treatment.Fasting blood glucose (FBG),total cholesterol (TC),triglycerides (TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C) and prostate specific antigen (PSA) were determined.Body mass index (BMI) and prostate volume (PV) were calculated.Relationship of classification and risk stratification in hypertension with BPH were analyzed.Results The levels of systolic blood pressurc (SBP),diastolic blood pressure (DBP),body weight,BMI,FBG and TC were higher (t=3.883,2.498,2.161,3.399,2.200,2.370,P＜0.05 or P＜0.01),while serum HDL-C were lower (t=2.036,P＜0.05) in hypertensive patients than in control group.Compared with the control group,IPSS and PV was increased (t =3.432,3.381,both P＜0.01) in hypertension group.Risk rate of hypertensive patients with BPH was 2.03 times (95％CI:1.33-3.11,P＜0.01) as compared with control group.In hypertensive patients,PV and IPSS were higher in level 2 or 3 grade group than in level 1 group (F=6.890,7.576,all P＜0.01).PV and IPSS in high risk and very high risk groups were enhanced as compared with those in low-medium risk group (F=30.608,19.804,all P＜0.01).Pearson analysis showed that PV was positively correlated with SBP,FBG and TC(r=0.223,0.251,0.305,all P＜0.05),while negatively correlated with HDL-C(r =-0.235,P＜0.05).Similarly,IPSS was positively correlated with SBP,DBP and FBG (r=0.396,0.273,0.224,all P＜0.01),while negatively correlated with HDL-C (r =-0.288,P＜ 0.01).Conclusions High incidence of BPH appears in the elderly men with hypertension.The increased PV and IPSS coexist with conventional risk factors of essential hypertension.Development of BPH is closely related to higher blood pressure and risk stratifications of hypertension.

Objective To explore the effects of amlodipine,perindopril and valsartan on plasma adiponectin and retinol binding protein 4 in elderly patients with essential hypertension.Methods From March 2007 to July 2010,238 elderly patients with essential hypertension were selected and 193 cases completed this study.Patients were randomly divided into 3 groups:amlodipine group (n=68),perindoprilgroup (n=60) and valsartan group (n=65).Patients in each group were treated with amlodipine,perindopril and valsartan respectively for at least 12 weeks.The changes in blood pressure,heart rate,body height,body mass index (BMI),abdominal circumference,waist circumference (WC),levels of blood lipids,plasma adiponection and retinol binding protein 4 were observed before and after treatment.Results Compared with pre-treatment,systolic blood pressure in 3 groups were significantly decreased after treatment (all P＜0.01).There were no significant differences in blood pressure among 3 groups after treatment (all P＞0.05).Compared with pre treatment,plasma adiponectin level was significantly increased in perindopril group and valsartan group after treatment [(7.4±1.8) μg/L vs.(8.3± 1.8) μg/L,(7.5±1.7) μg/L vs.(8.4±1.9)μg/L,both P＜0.01].Plasma adiponectin level was higher in perindopril group and valsartan group than in amlodipine group after treatment [(8.3±1.8) μg/L vs.(7.6±1.8) μg/L,(8.4±1.9) μg/Lvs.(7.6±1.8) μg/L,both P＜0.05].Compared with pretreatment,plasma retinol binding protein 4 level in 3 groups were all decreased after treatment,and the decrements had significant differences in perindopril group and valsartan group (both P＜0.01) but had no difference in amlodipine group (P＞0.05).Plasma adiponectin retinol binding protein 4 levels were lower in perindopril group and valsartan group than in amlodipine group after treatment[(36.6± 14.2) μg/L vs.(42.7± 13.8) μg/L,(36.3±14.1) μg/L vs.(42.7±13.8) μg/L,respectively,both P＜0.01].Conclusions Perindopril and valsartan play important roles in cardiovascular protection beyond the antihypertensive effects by increasing plasma adiponection level and decreasing plasma retinol binding protein 4 level in elderly patients with hypertension.
