Objective It aims to investigate prevalence of depressive symptoms among the elderly in community and to understand their related social factors. Methods Four neighborhood committees were randomly selected with cluster sampling as survey sites. Enrolled residents at age of 60 to 89 years were evaluated with a general background inventory and a geriatric depression scale(GDS). All the data were input to a microcomputer and were analyzed for its relevant factors with SPSS13. 0 software by multivariate logistic regression model. Results Totally, 1731 elderly people in the community were interviewed and rated with the inventory and scale mentioned above, and depressive symptoms were found in 297 of them, with prevalence of 17. 2 percent. Multivariate logistic regression analysis showed that there were seven factors associated to their depressive symptoms in the elderly, including family expenditure, housing condition, medical condition, familial support, hobbies in spare-time, ability to take care of oneself and participation to social activities. Conclusions A few social factors, such as living alone, insufficient income for family expenditure, disability of self care-taking, lack of hobby in spare-time, less participation to social activities, lack of familial support and severe chronic diseases by serf-evaluation, are all associated with depressive symptoms in the elderly.

Sheng's acupuncture manipulation at bone-nearby acupoints is a set of needling manipulation of the chief physician of TCM, SHENG Xie-sun, summarized through his over 50 years clinical experiences and on the basis of Internal Classic. Regarding this manipulation, on the premise of acupoint selection based on syndrome differentiation, the acupoints close to bone are possibly selected and punctured, with the needle tip toward bone edge, and followed by the technique to achieve reducing purpose. Clinically, the significant immediate analgesia can be achieved in pain disorders such as headache and toothache. Professor Sheng thought, corresponding to the location of needle insertion and needling depth, the tissue layers of needle tip passing through should be considered specially. The site of needle insertion should be changeable so as to ensure the needle tip reaching the bone. This manipulation for analgesia provides a certain guide for acupuncture study, especially for the mechanism study on acupuncture analgesia.

Objective: To investigate the effect of protein transduction domain-oligomerization domain-hemagglutinin (PTD-OD-HA) fusion proteins on tumorigenic ability of chronic myeloid leukemia (CML) BaF3-P210 cells in mice. Methods: The untreated BaF3-P210 cells and BaF3-P210 cells treated with 40 μmol/L PTD-OD-HA for 48 h were injected into BALB/c mice through the tail vein, respectively. The general status and survival time of mice in each group were observed. The number of peripheral white blood cells (WBCs) was counted. The Wright-Giemsa-stained blood and bone marrow smears were examined. The pathological changes of liver, spleen and lung tissues were observed by HE staining. The expression level of bcr/abl protein in bone marrow cells from mice was determined by Western blotting. Results: The incidence rates of CML in mice in the untreated BaF3-P210 cell group and the PTD-ODHA-treated BaF3-P210 cell group were 90% (9/10) and 80% (8/10), respectively; WBCs counts in the two groups were (44.3±4.8)×109/L and (20.6±3.2) ×109/L (P<0.05), respectively; the expression levels of bcr/abl protein in bone marrow cells in the two groups were 5.13±0.46 and 1.32±0.29 (P<0.05), respectively. The average survivals in the untreated BaF3-P210 cell group and the PTD-OD-HA-treated BaF3-P210 cell group were (101.3±6.2) d and (185.4±8.7) d (P<0.05), respectively. Wright-Giemsa staining showed that the infiltration degree of leukemic cells in bone marrow, liver and spleen was lower in the PTD-OD-HA-treated BaF3-P210 cell group than that in the untreated BaF3-P210 cell group. Conclusion: PTD-OD-HA can inhibit the tumorigenic ability of CML with BaF3-P210 cells in BALB/c mice. Copyright© 2011 by TUMOR.

OBJECTIVE: To determine the content of patchouli alcohol in Huodan pills (traditional Chinese medicine) by near-infrared (NIR) spectroscopy. METHODS: The content of patchouli alcohol in 147 batches of Huodan pills samples were determined by GC. NIR spectra of all samples were collected, then standard normal variate, first derivative and Norris derivative filter methods were used as spectral preprocessing tools, and at last, the calibration model of patchouli alcohol content was established by partial least squares regression. RESULTS: The correlation coefficients, the root-mean-square error of calibration, and the root-mean-square error of cross-validation of the calibration model for patchouli alcohol were 0.95509, 0.0315, and 0.04510, respectively; the root-mean-square error of prediction and the average recovery rate of validation samples were 0.0343 and 100.76%, respectively. CONCLUSION: The method is stable, accurate, and can be used to determine the content of patchouli alcohol in Huodan pills rapidly.

BACKGROUND: Learning and memory disorder exist in diabetic rats,which can be improved by APP 17-mer peptide. However, it is unclear whether learning and memory disorder in diabetes mellitus is caused by influencing neuronal mitochondrial transmembrane potentials and apoptosis in hippocampus or not and what is the related action mechanism of APP17-mer peptide.OBJECTIVE: To observe the effects of APP17-mer peptide on neuronal mitochondrial transmembrane potentials (△ψm) and apoptosis in hippocampal area of diabetic rats.DESIGN: A completely randomized, grouping and controlled trial.SETTING: Beijing Research Laboratory for Brain Aging, Beijing Xuanwu Hospital, Capital University of Medical Sciences; the Department of Endocrine, the First Central Hospital of Baoding.MATERIALS: The data measurement of the experiment was carried out in the Instrument Testing Center, the General Hospital of Chinese PLA between May 2002 and August 2002. The modeling and intervention of the experiment was carried out in the Animal Laboratory of Xuanwu Hospital, Capital University of Medical Sciences. Eighteen male Wistar rats were enrolled and randomized into control group, model group and APP17-mer peptide group with 6 rats in each group.METHODS: ① Diabetic models in the model and APP17-mer peptide groups were established by intraperitoneal injection of 60 mg/kg streptozotocin (pH=4.4) in fasted rats(fasting for 12 hours). Three days later, modeling was successful if blood sugar level in caudal vein was more than 15 mmol/L. Rats in the control group were not subjected to modeling.Then, the rats in the APP17-mer peptide group were subjected to the subcutaneous injection of APP17-mer peptide (3.4 μg for each rat once) three times a week and totally for ten weeks, whereas rats in the other groups were given saline of the same volume. ② After ten weeks, rats were anesthetized and decapitated to take out brain tissues, and then hippocampal tissues were isolated in ice bath for preparation of single cell suspension.JC-1 labeled mitochondrial transmembrane potentials and cell apoptosis in hippocampal area were measured by means of flow cytometry. ③ One-way analysis of variance was adopted in the comparison among groups.RESULTS: Eighteen rats were involved in the results analysis. ①Neuronal mitochondrial transmembrane potential was lower in the model group as compared with the control group [(551.91±53.36) vs (809.88±82.41) △ψm,P＜0.01] while it was higher in the APP17-mer peptide group as compared with the model group [(705.99±89.92) vs (551.91±53.36) △ψm, P ＜ 0.05].There was no difference between the APP17-mer peptide group and control group (P=0.146). ②) Apoptotic percentage of single cell in hippocampus was significantly higher in the model group than in the control and APP17-mer peptide groups [(5.32±1.37)%, (1.03±0.55)%, (2.80±0.92)%, P＜0.01, 0.05].CONCLUSION: Neuronal mitochondrial transmembrane potential and cell apoptosis in hippocampus may be involved in the occurrence and development of diabetes mellitus, and APP17-mer peptide plays an improved role in the process.

OBJECTIVEThis research aimed to analyze the three-dimensional position of mandibular canal (MC) and man of MC and its relationship with the surrounding structures dibular morphology of normal young males and females by using data from cone beam computed tomography (CBCT), as well as to provide an anatomical basis for clinical surgery of the mandible.

METHODSNormal occlusion and CBCT scans of 29 normal young people were conducted. InVivo 5 software was used to reconstruct the mandible, anchor the points, and measure the jaw shape and three-dimensional course of MC. All measurements were analyzed with SSPS 17.0 software.

RESULTSThe MC lingual bone cortex was thinner than the MC buccal bone cortex, and the distance of the MC to the buccal bone cortex gradually increased. However, the distance of the MC to the tongue bone cortex and alveolar crest gradually decreased from proximal to distal. In addition, the distance of the MC to the mandibular lower margin was minimal at the first molar and reached the maximum at the second premolar. No significant difference was observed among the heights, widths, and thicknesses of the left and right sides of the cortical bone of the mandibular body cross sections. From the midline to the farthest point, the height and lower one-third thickness of the lingual cortical bone of the mandibular body cross sections gradually decreased, whereas the width of the upper cross section and upper one-third thickness of the buccal cortical bone gradually increased. Significant difference was observed in some measured values.

CONCLUSIONAfter MC enter into the mandibular foramen, it moved away from the lingual to the buccal bone but gradually returned to the lingual bone; its general course is closer to the lingual bone. The mandibles of males are thicker than those of females. CBCT can accurately display the course of MC and its relationship with the surrounding structures.
