BACKGROUND: Chinese herb digan oral liquid promotes manufacture of hematopoietic cells. During irradiative injury, how are the therapeutic effects of intervention with Chinese herbal compound on expressions of stromal cellular adherent molecule (SCAM) and cyclin gene that are closely related to hematopoietic cells?OBJECTIVE: Mouse model with irradiative injury was established to assay the effects of Chinese herbal compound-digan oral lipid on the expression of medullary cyclinD1mRNA and the expressions of hematopoietic stem cells (HSCs), stromal cellular adherent molecular CD45 (SCAMCD45) and vascular cellular adherent moldecular-1 (VCAM-1).DESIGN: Randomized controlled experiment was designed.SETTING: Department of Integrated Traditional Chinese and Western Medicine, Wuhan General Hospital of Guangzhou Military Area Command of Chinese PLA; Institute of Hematology of Tongji Medical College and Institute of Hepatology of Hubei College of Traditional Chinese Medicine.MATERIALS: The experiment was performed in Institute of Hematology of Tongji Medical College and Institute of Hepatology of Hubei College of Traditional Chinese Medicine from January 2001 to June 2002, in which,48 outbred Kunming mice were employed, aged varied from 8 to 12weeks, mass-weighted varied from 18 to 22 g, of either sex. Drugs: 100% digan oral lipid is composed of shudihuang (radix rehmanniae preparata) and zhigancao (radix glycyrrhizae preparata). At ratio of 2/1, water decoction was prepared and concentrated as 100% oral liquid (containing raw herb 1 g/mL). METHODS: Totally 48 mice were randomized into 4 groups, 12 mice in each one. Normal group: no any management. Oral lipid group: Digan oral lipid was applied for gastric perfusion in model with irradiative injury,0.02 ml/g, twice a day. Model group: After modeling, physiological saline was used for gastric perfusion with the same dosage as the above. Batilol group: After modeling, batilol suspension was used for gastric perfusion (0.1 g/kg). Gastric perfusion was done continuously for 9 days in each group. On the 10th day, hybridization in situ was used to assay cyclinD1 mRNA expression of medullary mononuclear cell (MNC), Immuniohisto chemical SABC method was used to assay medullary VCAM-1 expression and flow cytometry (FCM) was used to assay CD45 content.MAIN OUTCOME MEASURES: CyclinD1 mRNA expression of medullary mononuclear cell (MNC) and expression of medullary stromal cellular VCAM-1 and CD45 antigenRESULTS: After modeling, there were 12 mice in normal group and 10 mice in rest groups. In result analysis, 5 mice were randomized in each group. ① In oral liquid group, the expression of medullary cellular cyclinD1 mRNA and VCAM-1 were higher significantly than model group[oralliquid group: (27.34±4.49), (53.94±8.67)% and model group: (16.06±4.57),(31.92±5.01)%, P＜ 0.01]. ② Expression of CD45 antigen iroral liquid group was higher significantly than model group [(41.38±5.76), (19.24±4.98)%, P ＜ 0.01]. Both digan oral liquid and batilol improved the expressions of cyclinD1,VCAM-1 and CD45 antigen.CONCLUSION: Chinese herbal compound-digan oral liquid enhances the expression of adherent molecule of hematopoietic stem cells, promotes the expression of stroma] cellular adherent molecule and improves the transcription of medullary cellular cyclinD1, which induces hematopoietic cells to be differentiated more maturely and to be transported peripherally so as to supplement blood.

In this paper, we propose a new active contour algorithm, i. e. hierarchical contextual active contour (HCAC), and apply it to automatic liver segmentation from three-dimensional CT (3D-CT) images. HCAC is a learning-based method and can be divided into two stages. At the first stage, i.e. the training stage, given a set of abdominal 3D-CT training images and the corresponding manual liver labels, we tried to establish a mapping between automatic segmentations (in each round) and manual reference segmentations via context features, and obtained a series of self-correcting classifiers. At the second stage, i.e. the segmentation stage, we firstly used the basic active contour to segment the image and subsequently used the contextual active contour (CAC) iteratively, which combines the image information and the current shape model, to improve the segmentation result. The current shape model is produced by the corresponding self-correcting classifier (the input is the previous automatic segmentation result). The proposed method was evaluated on the datasets of MICCAI 2007 liver segmentation challenge. The experimental results showed that we would get more and more accurate segmentation results by the iterative steps and the satisfied results would be obtained after about six rounds of iterations.

Objective To analyze the clinical characteristics of renal cell carcinoma (RCC) and unveil the current status of diagnosis and treatments. Methods The registry data from 23 medical centers cover different areas of China. A total of 2030 new cases of RCCs in the 23 centers from Au-gust 2007 to October 2008 were collected, in which 1975 cases had integrated data for analysis. The symptoms, diagnostic techniques, pathology features, and therapeutic selection were analyzed. Re-sults A total of 1975 new cases were reviewed, with 1329 males and 634 females. The male and fe-male ratio was about 2.1 : 1.0. Of all cases, 1238 patients (62.7%) were asymptomatic and detected by examination, while 711 patients (36.0%) were symptomatic. 1260 patients (63.8%) were clinical stage Ⅰ , most of them were asymptomatic. 1844 patients were treated surgically, 1500(81.3%) un-derwent radical nephrectomy, 325 (17. 6%) underwent partial nephrectomy. Among the operations, open operation was performed in 1493 cases(81.0%), laparoscopic procedure in 351 cases(19.0%). There were 1522(84.5%) clear cell carcinomas, 98 (5.44%) papilliform renal cell carcinomas. Con-clusions Routine health examination could be an important way to diagnose early stage RCC. Open radical nephrectomy is the most often used surgical technique among the centres of present study.

Objective To provide objective evidences for early screening of the hypothalamic-pituitary-adrenal(HPA)axis function in diabetic patients, the relationship between HPA axis function and diabetes mellitus was systematically reviewed. Methods PubMed, Ovid, Embase, Web of science Databases were retrieved from articles reporting the relationship between HPA axis function and diabetes mellitus. Meta-analysis were carried out by Stata 12. 0 software for heterogeneity test and data merged among articles for the inclusion and exclusion criteria. Results Our meta-analysis showed the following results: Compared with control group, the basal plasma cortisol level in total diabetes group, T1DM group, T2DM group, diabetes patients(with or without chronic complications)combined with hypertension was significantly higher. Compared with control group, postdexamethasone cortisol level was markedly higher in diabetes group. There was no significant difference in 24 h urinary free cortisol(24h UFC)and ACTH levels between diabetes group and control group. Our qualitative evaluation shows the following results: the differences of awaking salivary cortisol and cortisol awakening response(CAR)between the two groups were inconsistent among all included studies. Most studies showed that CAR was lower in diabetic patients. Conclusion The present analysis has demonstrated that HPA axis dysfunction exists along with diabetes mellitus, and diabetic comorbidity may further worsen the HPA axis dysfunction.

BACKGROUND:During the outbreak of severe acute respiratory syndrome(SARS),certain people had been isolated by various reasons and appeared a series of psychological, physical and behavioral reactions. OBJECTIVE:To understand the different defensive features in people with different level of mental health in the isolated population, and explore the relationship between defensive style and mental health. DESIGN:An in investigative study taking the isolated population during outbreak of SARS as the subjects. SETTING:A psychiatric department of a military hospital. PARTICIPANTS:Totally 187 people of different sex,age and education, who were isolated during April and May 2003 due to SARS outbreak in a city of northwest China,were selected as the subjects. INTERVENTIONS:The 187 subjects,who were isolated due to SARS outbreak,were evaluated by using the symptom checklist(SCL 90) and defense style questionnaire(DSQ). RESULTS:About 36.4% people of this population had distinct mental or physical health problems that were characterized by anxiety,horror,depression,hostility and compulsion.There was difference in defensive styles between the high symptom group and low symptom group,among which the score of DSQ factors in the immature type of high and low symptom groups were 5.72± 1.56 and 4.35± 0.96 respectively while the scores in the intermediate type defense were 4.98± 1.44 and 3.72± 0.89 respectively(P< 0.01).Mental health problem was positively correlated with the application of immature defensive style,but had negative correlation with application of mature defensive means. CONCLUSION:There is difference in the defensive styles among the isolated people with different mental health status,and their defensive strategies are closely related to the mental health.
