Objective To observe the clinical, mammographic and sonographic features of pure invasive lobular breast carcinoma (ILC), and to explore the value of combined imaging assessment of ILC. Methods Sonographic appearances of 55 patients of ILC were retrospectively reviewed in correlation with mammographic, pathologic and clinical findings, and the causes of false negative were analyzed. Results The main features found in clinical examination were mass (96.15%) and thickening in the size of breast (3.85%). The main mammographic features were spiculated or ill-defined mass (65.38%) and architectural distortion (23.08%). The most common sonographic patterns were mass (98.00%) and distortion (2.00%). The accuracy for detecting ILC of clinical examination, mammography and ultrasonography was 94.55%, 83.87% and 98.04%, respectively, while combining the three modalities, the detection rate increased to 100%. Conclusion Sonography has higher accuracy than mammography in detecting ILC. Combining clinical examination, mammography and ultrasonography can increase the pre-operative diagnostic accuracy of ILC.

OBJECTIVETo observe the efficacy on primary osteoporosis treated with spreading moxibustion for warming yang and activating blood circulation so as to provide the effective clinical therapeutic methods for osteoporosis.

METHODSSixty cases of primary osteoporosis were randomized into a spreading moxibustion group (30 cases) and a calcium tablet group (30 cases). In the calcium tablet group, caltrate was prescribed for oral administration, 600 mg per day. In the spreading moxibustion group, on the basis of the treatment as the calcium tablet group, the spreading moxibustion was applied at Dazhui (GV 14) to Yaoshu (GV 2) for warming yang and activating blood circulation. The duration of treatment was 12 weeks. Visual analogue scale (VAS) score, TCM clinical symptom score and bone mineral density (BMD) were observed and compared before and after treatment in the patients between the two groups.

RESULTSVAS scores were reduced apparently after treatment in the two groups (both P < 0.01) and the results in the spreading moxibustion group were obviously superior to that in the calcium tablet group (2.36 +/- 0.43 vs 4.52 +/- 0.35, P < 0.01). BMD were all increased in the two groups (P < 0.05, P < 0.01) and the results in the spreading moxibustion group were superior to those in the calcium tablet group (both P < 0.05). The total clinical effective rate was 86.67% (26/30) in the spreading moxibustion group, apparently better than 63.33% (19/30) in the calcium tablet group (P < 0.05). TCM clinical symptom scores after treatment were all reduced apparently in the two groups (both P < 0.01), and the result in the spreading moxibustion group was obviously superior to that in the calcium tablet group (4.72 +/- 1.90 vs 6.82 +/- 2.30, P < 0.01). The total effective rate of TCM symptoms was 93.33% (28/30) in the spreading moxibustion group, apparently better than 70.00% (21/30) in the calcium tablet group (P < 0.05).

CONCLUSIONThe combined therapy of spreading moxibustion for warming yang and activating blood circulation and the oral administration of caltrate apparently relieves pain and TCM clinical symptoms, improves BMD in the patients of osteoporosis and achieves definite clinical efficacy in the patients of osteoporosis.

Objective To evaluate the effectiveness of the current measure of Oncomelania hupensis control in Jiangsu Province. Methods The snail control was carried out with molluscicides in the high transmission areas every year. Some snail habitat areas were modified. The snail areas within three years were re-treated with molluscicides in the maintenance phase. The snail survey was carried out every spring, and the data were analysed with SAS software. Results From 1995 to 2001, 14519.17 hm 2 of snail habitats were molluscicided, 2768.57 hm 2 were modified, and 8803.64 hm 2 were re-treated with molluscicides in the maintenance phase. The coverage rates of snail control areas dropped by 19.14% every year. The snail areas increased by 6.25% every year from 1995 to 2002. In which, the areas of infected snails increased by 18.52% every year. The correlation analysis showed that the areas of infected snails increased with the increasing of the total snail areas. At the same time, the areas of infected snails increased with the fall of the coverage rates of snail control areas. The analysis of the snail distribution showed that the main problem was poor snail control. Conclusion In recent years, the rise of area of snail habitats is serious in Jiangsu Province. The present measures of the snail control have not effectively stopped the spreading and increasing of snails. The research on the new molluscicides, the new methods of snail control and the better policies are very important.

OBJECTIVE: To observe the effect of moxibustion of acupoints of the Governor Vessel on the levels of cellular autophagy, β amyloid protein (Aβ) immunoactivity, and expression of LC3-Ⅰ， LC3-Ⅱ， p62 and p-P70S6K proteins in the hippocampal tissue of APPswe/PS1de9 (APP/PS1) double-transgenic Alzheimer's disease (AD) mice, so as to reveal its underlying mechanisms in improving AD. METHODS: APP/PS1 double-transgenic AD mice were randomly divided into AD model, moxibustion, autophagy-inducer (Rapamycin) and autophagy-inhibitor (3-MA)＋moxibustion groups (n＝10 in each group), and other 10 C57BL/6J male mice (the same age) were used as the normal control group. Herbal-cake (made of Chuanwu [Radix Aconiti Praeparata]) partitioned moxibustion was applied to "Baihui"(GV20), moxibustion was applied to "Fengfu"(GV16) and "Dazhui"(GV14), all for 20 min, once daily for 2 weeks, with one day's off between two weeks. For mice of the autophagy-inducer and 3-MA＋moxibustion groups, Rapamycin (2 mg•kg－1•d－1) and 3-MA (1.5 mg•kg－1•d－1) were separately administered by intraperitoneal injection for 2 weeks. The cognitive ability was examined by Morris water maze tests, and the ultrastructural changes (including autophagic lysosomes, etc.) of hippocampal neurons were observed by using transmission electron microscopy. The immunoactivity of cerebral cortex and hippocampal Amyloid β peptide 1-42 (Aβ1-42) was detected by immunohistochemistry, and the expression levels of hippocampal LC3-Ⅰ， LC3-Ⅱ， p62 and p-P70S6K proteins were detected by Western blot. RESULTS: After modeling, the escape latency of Morris water maze tasks was prolonged in the model group than in the normal control group (P<0.05) and obviously shortened in the moxibustion and autophagy-inducer groups (not the autophagy-inhibitor group) than in the model group (P<0.05). Results of transmission electron microscope showed deformed, irregular or atrophic neurons with rough and incomplete and fuzzy nuclear membrane, and decreased intracellular autophagosomes in the hippocampus in the model group, and partial irregular, atrophic neurons with more autophagic vesicles and lysosomes in the moxibustion group. The expression levels of Aβ1-42 in both cerebral cortex and hippocampus tissues, and LC3-Ⅰ， p62 and p-P70S6K proteins in the hippocampus were consi-derably up-regulated in the model group relevant to the normal control group (P<0.01), and evidently down-regulated in both moxibustion and autophagy-inducer groups (not the autophagy-inhibitor group) than in the model group (P<0.01), while that of hippocampal LC3-Ⅱ protein and LC3-Ⅱ/Ⅰ ratio levels were obviously down-regulated in the model group relevant to the normal control group (P<0.01), and significantly up-regulated in both moxibustion and autophagy-inducer groups (not the autophagy-inhibitor group) than in the model group (P<0.01)．. CONCLUSION: Moxibustion can improve the cognitive ability of APP/PS1 double-transgenic AD mice, which is associated with its effects in promoting hip-pocampal and cerebral cortex autophagy level, and down-regulating the expression levels of Aβ1-42, LC3-Ⅰ， p62 and p-P70S6K proteins in the hippocampus.

Objective To explore the value of readout segmentation of long variable echo-trains (RESOLVE) in the differentiation of prostate cancer from benign prostatic hyperplasia (BPH).Methods Seventy two consecutive patients with suspected prostate cancer were evaluated by 3.0 T MR examination (RESOLVE sequence included,b values=0 and 800 s/mm2) were included in our retrospective study.All the patients had ultrasound guided systemic biopsy with histopathological diagnosis.The patients were divided into group A (23 prostate cancer cases with total 43 malignant lesions) and group B (49 BPH cases with total 64 benign lesions).Two radiologists who were blinded to the clinical data quantitatively analyzed the ADC values of suspicious lesions independently.Inter-reader agreement for ADC values was assessed with Bland and Altman test,and the intra-class correlation coefficient (ICC).Difference of ADC values in two groups was assessed by student's t test.Receiver operating characteristic curve (ROC) was used to determine the best predictor and cutoff value.Results A total of 107 lesions (43 malignant and 64 benign) were identified in 72 patients.ICC was 0.976,P＜0.01.The mean ADC value of prostate cancer is lower than BPH (t=19.223,P＜0.01),(0.74±0.12) × 10 3 and (1.21±0.12) × 10-3mm2/s respectively.Diagnostic cut-off point was 0.946× 10-3mm2/s,diagnostic sensitivity 95.3 ％ (41/43),specificity 98.4％ (63/64),accuracy 97.2％ (104/107).Conclusion RESOLVE ADC value is valuable in the differential diagnosis of prostate cancer and BPH.
