Objective To investigate the mocelualr mechanism of Cordycepin negative modulates LPSinduced cytokine production in murine macrophages.Methods The RAW264.7 murine macrophages were cultured in vitro and were pre-treated by different concentration of Cordycepin,and then stimulated by LPS for 8 h.Production of TNF-o,IL-6 and IL-12,and the content of p65 in the nuclear were detected by ELISA.Expression of heme oxygenase-1 (HO-1) and phosphorylation of IκB and p38 were measured by Western blot.Nuclear translocation of Nrf2 was detected by Immunofluorescence.Results 1 ～ 30 μg/mL of Cordycepin treatment significantly abrogated LPS-induced TNF-α,IL-6 and IL-12 production,p65 nuclear translocation and IκB phosphorylation.In addition,different concentration of Cordycepin could also induce RAW264.7 cells expression of HO-1,phosphorylation of p38 and nuclear translocation of Nrf2.Application of p38 inhibitor and small interfering RNA-mediated knock-down of Nrf-2 significantly inhibited surfactin-induced HO-1 expression.Treatment with a selective inhibitor of HO-1 reversed the Cordycepin mediated inhibition of pro-inflammatory cytokines.Conclusions Cordycepin induces antiinflammatory effects by inhibition of NF-κB and activation of Nrf-2 and p38 mediated HO-1 induction.

The genetic diversity of three Tibetan herbs, i. e., Sang-Di, E-Dewa and Ye-Xingba (Tibetan names), was studied based on the field collection, specimen identification and DNA sequence analysis. Swertia hispidicalyx, Gentiana lhassica and Scrophularia dentata, as the original plants of the three Tibetan herbs, were collected and identified. The regions of ITS, matK, rbcL, rpoC1, trnL(UAA), psbA-trnH, atpB-rbcL, trnS (GCU)-trnG(UCC), rpl20-rps12, trnL(UAA)-trnF(GAA) and nadl 2nd intron were amplified and sequenced. The ITS regions of S. hispidicalyx and S. dentata were cloned and sequenced, and the sequences were classified into different genotypes. All the sequences were analyzed and compared with those of closely related species. Our studies may provide reference for the genetic diversity analysis and molecular identification of the three Tibetan herbs.

Objective This study aimed to discuss the different assessment of pain among medical and nursing staff and cancer patients and supply reference for proper analgesic precept for clinical application and nursing measures. Methods We collected the assessment of psychological pain and physiological pain by 55 hospitalization cancer patients, 40 physicians in-charge and 55 nurses in-charge in one week by Johnson inventory. The assessment results were compared and at the same time the relevant problems of the attitude to cancer pain by patients was also investigated. Results Improper recognition existed in cancer pain treatment by most cancer patients. The physiological pain was higher than the psychological pain assessed by both patients and nurses (P<0.05). But the pain assessment by patients was higher than that by the nurses (P<0.05). The assessment of psychological pain was higher than the physiological pain by doctors and both aspects were lower than those by patients, but no statistical difference was seen (P>0.05). The assessment by doctors was more accurate than that by nurses. Conclusions Routine establishment of pain assessment inventory for patients could instruct patients how to record the degree of their pain. We should strengthen the standard training about pain management knowledge and give timely communication with patients' cancer pain.

Objective To systematic evaluation the antiepileptic drug valproic acid and topiramate effects on body weight and plasma leptin levels.Methods By searching the Cochrane Library,PubMed,EMBASE,CNKI,VIP Chinese Scientific Journals Database and Articles Database (from building a database to August 1,2014),qualified RCT was chosen from those articles according to inclusion and exclusion criterias and evaluated their quality.Then the meta-analysis was performed by Rev Man 5.3.Results (1) A total of 70 documents retrieved for the evaluation,12 of the literatures could be incorporated into the Meta-analysis,including a total of 634 participants,9 literatures using valproate to treat epilepsy,4 literatures used topiramate.(2)Meta-analysis:compared with other drugs,valproic acid treatment increased body mass index and leptin level in patients with epilepsy,BMI combined MD=0.88(95％ CI:0.45-1.31),leptin level in the combined MD=0.58(95％ CI:0.07-1.09);compared with other drugs,topiramate affect body mass index and leptin level in patients with epilepsy had no statical difference,BMI combined MD=-0.02 (95％ CI:-0.62-0.58),leptin levels in the combined MD =-0.05(95％ CI:-0.31-0.20).Conclusion Antiepileptic drug valproic acid may increase patients' BMI and serum leptin levels,yet topiramate in do not have influence in patients BMI and serum leptin levels;more basic and clinical researches are needed to explore serum leptin levels and the exact therapy mechanisms of antiepileptic drugs for clinicians to select antiepileptic drugs.

Objective To investigate the most important risk factors leading to failure of replantation of severed distal fingers so as to provide theoretic foundation for an improvement of survival rate. Methods Medical records of 65 amputated distal fingers underwent replantation were retrospectively studied to determine the independent risk factor for failure by using univariate and multivariate statistical analyses. Results Of 65 fingers treated with replantation, 8 (12%) failed. Univariate analysis showed that the increase of platelet level was the risk factor leading to failure of replantation (P= 0.041) . Manner of venous drainage (? 2=12.483, P=0.002), injury cause (? 2= 7.992, P= 0.018) , reconstruction of arteries (? 2=4.158, P=0.041) and preservation of the severed finger (? 2=6.240, P=0.044) were significantly correlated with the failure of replantation. However, multivariate logistic regression analyses showed that platelet level (OR=1.020, P=0.046) and manner of venous drainage (OR=0.154, P=0.040) were the significant independent predictors for failure of replantation. Six (38%) out of 16 amputated fingers replantation by means of single venous anastomosis resulted in failure. Of 26 amputated fingers treated with single venous drainage by bloodletting of finger tip, one (4%) failed. However, only one finger (4%) failed when 23 amputated fingers were treated with venous reflux by a combination of these two ways. Conclusions High level of platelet and venous reflux through anastomosis are the independent predictors affecting replantation of the severed fingers. Augmentation of anticoagulation as well as venous drainage determined by concrete lesion condition contribute to a higher clinical survival rate of replantation.

Objective To investigate the protective effects of total rhizoma panacis japonica saponins (tRPJS)on rat brains after focal cerebral ischemia injury, and to explore its protective mechanisms of tRPJS. Methods Focal cerebral ischemia in rats was produced by 24 h occlusion the right part of the middle cerebral artery(MCAO).The activities of glutathione peroxidase (GSH-PX), superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA)in ischemic tissue of brain as well as the brain pathological changes were analyzed. Results The activities of GSH-PX, SOD and CAT were lowered and the content of MDA was elevated in the model rats. Treatment with tRPJS 200, 100, 50 mg? kg-1 could significantly improve the activities of all the enzymes mentioned above and reduce the content of MDA in ischemic tissue of brain. Conclusion The tRPJS has protective effect against focal cerebral ischemic injury and this may be related to the increase of activities the GSH-PX, SOD and CAT and to the reduction of the lipid peroxidation.

Objective To investigate the epidemiological characteristics of children infected by mycoplasma pneumoniae(MP)over the last five years in Kunming region.Methods Indirect immunofluorescence assay was used to detect blood MP-IgM of hospitalized patients from January 2003 to December 2007 in order to determine the age and gender distribution characteristics of MP infection and to investigate the epidemiological features of the five years' results.Results Infection incidences by MP in Kunming region over the last five years were 20.9%,14.3%,17.5%,15.7%and 19.5%,respectively.Statistical significance was found among the groups mentioned above(P＜0.01).The MP infection incidences in different age groups were 10.7%(～1 year old),20.5%(～3 years' old),21.5%(～6 years' old)and 21.7%(～14 years' old).MP infection incidences showed age and gender characteristics(P＜0.01).Infants showed lower NIP infection incidence and infection incidence was higher in female.The epidemiological investigation indicated that MP infection incidences varied from year to year(P＜0.01).The infection incidences of 2003 and 2007 by MP were higher than those of the other years.There were epidemiological differences in infection incidences by NIP over last five years(summer,autumn and winter).The MP infection incidences showed seasonal differences(P＜0.01).Conclusion Mycoplasma pneumoniae was the main local causative agent responsible for respiratory tract infection in children aged under one years' old in Kunming region.Over the last five years,there were two outbreaks in the local area,but with no seasonal regularity of epidemiology.

Objective To observe and compare the effects of acupuncture and acupuncture plus speech therapy on activation of the brain areas in aphasic patients by use of oxygenation level dependent-functional magnetic resonance imaging (BOLD-fMRI).Methods Twenty patients with aphasia caused by stroke were randomized into two groups by use of random number table (10 cases in each group):an experimental group subject to acupuncture treatment combined with speech therapy,and a control group subject to speech therapy only.All the cases were dextromanuality.On admission and after 1 month of treatment,BOLD-fMRI was used to test signals of the activated brain areas of both group,and Aphasia Battery of the Chinese (ABC) was employed to evaluate the changes of speech ability of the patients.Results During the study,1 case from control group was unable to do the post-intervention evaluation due to onset of the second stroke.The effective rates of the control and experimental group were 55.56％ and 100.00％,respectively,and recovery of verbal ability in experimental group was significantly better than in control group (P ＜ 0.05).The active volume and extent in brain were significantly increased in both groups (P ＜0.05),and a comparison between the two groups showed that the changes in activation volume and extent of the brain were significantly greater extensive in experimental group than in the control group,especially in bilateral frontal lobe,cuneus,posterior cingulate gyrus,lingual gyrus,occipital lobe,splenium of corpus callosum,cerebellar hemisphere,and the left precentral gyrus,post-central gyrus,paracentral lobule,temporal lobes,angular gyrus,precuneus,and the right hippocampus,parahippocampus gyrus.Conclusion Acupuncture combined with speech therapy could cause changes in activation patterns of the brain areas,which may contribute to the improvement of verbal ability of the aphasic patients.
