Objective:To investigate the status of rumination in patients with primary glaucomatous visual field defect and explore the influencing factors.Methods:Totally 267 patients with primary glaucomatous visual field defect were selected via convenience sampling method. Invasive rumination, purpose rumination, and self-management behaviors among different visual field were compared. The main influencing factors of invasive rumination and purpose rumination were analyzed.Results:Total score of rumination in patients with primary glaucomatous visual field defect was (29.90±5.58) points, average item score of self-management behaviors was (2.81±0.31) points. There were no significant difference in invasive rumination, purpose rumination, self-management behaviors among different visual field ( P>0.05). Accidental injury, life adjustment, income of family per mouth and degree of education could explain 30.7% of the total invasive rumination variation; disease management, body function promotion and accidental injury could explain 11.1% of the total purpose rumination variation. Conclusions:Rumination and self-management behaviors in patients with primary glaucomatous visual field were at a lower middle level and middle level respectively. Medical staff should attach importance to assess the invasive rumination among these patients with accidental injury, poor ability of life adjustment, low income of family per mouth and low degree of education. Through lowering the negative experience, changing the cognitive and taking correct self-management behaviors, then prognosis of disease would be improved.

Objective To assess the feasibility of a novel 99Tcm labelled polypeptide analogue for interleukin-11 receptor ( IL11R) imaging in a bone metastases model for prostate cancer. Methods A novel circular polypeptide analogue of IL11 ( c( CGRRAGGSC ) ) was indirectly labeled with 99Tcm and the product was named as 99Tcm-DTPA-IL11 RR. The labeling efficiency, radiochemical purity and stability of the product were measured with paper chromatography and high performance liquid chromatography (HPLC). The biodistribution of 99Tcm-DTPA-IL11RR was investigated in 28 ICR normal mice. The organ radioactivity was measured as percentage activity of injection dose per gram of tissue ( %ID/g). The models of bone metastases from prostate cancer were established at the tibias of BALB/c nude mice bearing human prostate cancer PC-3 cells. The tumor bearing ( n= 5 ) and standard closed fracture nude mice models underwent both 99Tcm-DTPA-IL11RR and 99Tcm-methylene diphosphonate (MDP) scintigraphy study. The images were acquired at 0.5, 1,2, 4, 6, 8, 24 h after intravenous injection of the tracers. The competitive inhibition imaging was perfomed in three tumor bearing mice. One-way variance analysis was used. Results The labeling efficiency was 90.7%. The radiochemical purity of 99Tcm-DTPA-IL11RR in normal saline solution was (99.57 ±0.09)%, (99.29 ±0.18)%, (98.95 ±0.78)%, (98.67 ±0.11)%, (96.53 ±0.91)%, (95.20±0.70)%, (88.38 ±0.22)% and (36.17±1.29)% at room temperature after0, 1,2, 3, 4, 6, 8 and 24 h, respectively. The tracer radiochemical purity in the blood of ICR mice remained over 90% at 37 C for 6 h. The labeling compounds were excreted mainly through kidney. The peak uptake of bone ( ( 1.910 ±0.109) %ID/g) and liver ( (0.366 ±0.030) %ID/g) was at 4 h after injection. In the tumor bearing mice, the uptake of spine marrow and large joints of extremities was mild. The highest uptake at tumor region was at 4 h and persistent at 6-8 h after injection. The tumor to non-tumor ratios (T/NT) were 1.17 ±0.17, 2.20 ±0.29, 3.20 ±0.15, 3.67 ±0.23, 13.61±0.85, 9.45 ±0.37 and 3.33 ±0.30 at 0.5,1, 2, 4, 6, 8 and 24 h, respectively (F=621.54, P＜0.05). In the standard closed fracture models,high uptake of 99Tcm-MDP was shown at the fracture site, with no increased 99Tcm-DTPA-IL11RR uptake noted. The tumor uptake was significantly depressed after a pre-injection of the unlabeled polypeptide analogue. Conclusions The synthesis of 99Tcm-DTPA-IL11RR is stable and the labeling efficiency is high. It may be a potential molecular probe in metastatic bone imaging for prostate cancer.

ObjectiveTo evaluate the ability of high resolution magnetic resonance (MR) imaging at 3.0 tesla to depict the characterization of human carotid arterial vessel wall and detect atherosclerotic lesions ex vivo in comparison to histopathologic results. MethodsEighteen carotid arteries obtained from 9 elderly donors underwent fat-suppressed T1 - and T2-weighted MR imaging at 3.0 tesla MR system with a mouse coil. Corresponding histological sections were obtained for the comparison. Correlation between MR images and histopathologic slices was obtained by Pearson or Spearman correlation coefficient.Cohen K was computed to quantify the agreement between MRI and histopathologic findings.Results Lumen area,intima and media area measured on fat-suppressed T2-weighted images showed stronger correlation with the corresponding histopathologic slices [ MRI vs.histopathology:( 27. 53 ± 6. 77 ) mm2 vs.( 25.83 ±6. 69 ) mm2, r2 ＝ 0. 91,P2 ＝ 0. 024, ( 12.31 ± 3. 31 ) mm2 vs.( 12. 28 ± 3.71 ) mm2, r2 ＝ 0. 70, P2 ＝ 0. 020,Median 12. 29 mm2(Min 1.12 mm2, Max 33.18 mm2) vs.Median 11.62 mm2(Min 0.89 mm2, Max 32. 84 mm2 ), r2 ＝ 0. 74, P2 ＝ 0. 016, respectively]. The Cohen K score between the MR imaging and American Heart Association classifications was 0. 74, which corresponds to a good agreement. Conclusions 3.0 T high-resolution multi-sequence MRI can clearly show the structure of ex vivo carotid artery wall and allow quantitative assessment.Fat-suppressed T2Wimaging has a greater advantagein presenting atherosclerotic lesions.

OBJECTIVETo observe the effects of electroacupuncture (EA) with branch-foundation acupoint combination on the indices regarding pituitary-target gland axis in aging rats with yang deficiency, so as to explore its regulating mechanism on aging rats with yang deficiency.

METHODSForty healthy Sprague-Dawley female rats were randomly divided into a normal control group, a model group, an EA group and an EA control group, 10 rats in each group. Except the normal control group, the rats in the rest 3 groups were all treated with subcutaneous injection of D-galactose for 40 d, followed by intramuscular injection of hydrocortisone for 7 d to establish aging model with yang deficiency. After the successful establishment of model, the EA group was treated with EA at "Guanyuan" (CV 4), "Housanli" (ST 36) and "Baihui "(GV 20) while the EA control group was treated with EA at "Zhongji" (CV 3) "Yinlingquan" (SP 9) and "Yintang" (GV 29); the rats in the normal control group and model group were immobilized and fixed during the same time period. The treatments were given 6 times per week totally for 4 weeks. With radiation immunity analysis method, the 8 biological indices of pituitary-target gland axis, including thyroid-stimulating hormone (TSH), triiodothyronine (T3), tetraiodothyronine-4 (T4), adrenocorticotropic hormone (ACTH), corticosterone (CORT), estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were detected to observe the changes of their content.

RESULTSCompared with the normal control group, the serum level of TSH, T3, T4 and E2 were reduced in the model group (P<0.05, P< 0.01) while those of ACTH, CORT, FSH and LH were increased (P<0.05, P<0.01). Compared with the model group, the serum level of TSH, T3, T4 and E2 were increased in the EA group (P<0.05, P<0.01) while those of ACTH, CORT, FSH and LH were significantly reduced (P<0.05, P<0.01). Compared with the EA control group, the content of TSH was increased in the EA group without statistical significance (P>0.05), that of T3, T4 and E2 was increased (all P<0.05) and that of ACTH, CORT, FSH and LH was significantly reduced (all P<0.05).

CONCLUSIONThe electroacupuncture with branch-foundation acupoint combination has benign regulating effects on the key hormones of pituitary-target gland axis, which could effectively improve the dysfunction of pituitary-target gland axis that is caused by aging with yang deficiency; the efficacy of electroacupuncture with branch-foundation acupoint combination is superior to that of adjacent control acupoint combination.
