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.

Objective To analysis the effect of compound betamethasone injection combined with radiation on keloid in frontal facial region. Methods 60 cases of keloid patients in zhejiangprovincial people's hospital from January 2014 to January 2016 were selected,all patients were treated with surgery,the patients were randomly divided into observation group and control group,30 cases in each group,radiotherapy was used in the control group,the observation group was treated with local injection of compound betamethasone on the basis of the control group,the therapeutic effects, pain scores, adverse reactions and complications were compared between the two groups. Results The recurrence rate of the observation group was 3.33% which was significantly lower than that of the control group 10%,the improvement rate of the observation group 93.33% was significantly higher than the control group 80%,the difference was statistically significant (P<0.05).one,two and three months after operation,the pain scores in the observation group were significantly lower than those in the control group at the same time point,the difference was statistically significant (P<0.05).The adverse reaction rate was 6.66% (2/30) in the observation group and 23.33% (7/30) in the control group, there was no significant difference between the two groups.The incidences of skin sag, pigmentation, incision delayed union and telangiectasia in the observation group were significantly lower than those in the control group (P<0.05). Conclusion Compound betamethasone injection combined with radiation on the frontal facial keloid patients with significant effect,can significantly reduce the recurrence rate,improve the rate of improvement,reduce pain and complications in patients.

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.

Objective To investigate the suitable injection rate and dose in multi-slice CT perfusion imaging.Methods Randomized block design was adopted in this study.The treatment factor-contrast medium injection rate was classified into 3,4,5,6 and 8 ml/s;thesubjects were divided into 5 blocks grouped by contrast medium injection dose: 0.5,0.75,1,1.25 and 1.5 ml/kg.25 Beagles wererandomly enrolled to undergo cerebral CT perfusion imaging.After post processing,time to peak(TTP) and rise value(RV) were measured in superior sagital venous.Results Injection rate had a significant effect on TTP of superior sagital venous.There was no significant difference among group 5,6 and 8 ml/s.Compared with 8 ml/s,TTP of superior sagital venous was prolonged when injection rate 3,4 ml/swere adopted.Injection dose had a significant effect on RV of superior sagital venous.There was no significant difference among group 1,1.25 and 1.5 ml/kg.In comparison with 1 ml/kg,RV of superior sagital venous was prolonged when injection dose 0.5 and 0.75 ml/kg were adopted.Conclusion The quality of cerebral CT perfusion imaging is well enough even injection rate as low as 5 ml/s or injection dose as few as 1 ml/kg.
