CpG oligodeoxynucleotides (ODN) have potent immunostimulatory effects and can enhance the anti-cancer activity of cancer treatments. CpG ODN directly induced the activation and maturation of plasmacytoid dendritic cells, stimulated the secretion of Th1-type cytokines, and enhanced the differentiation of B cells into antibody-secreting plasma cells. CpG oligodeoxynucleotides as vaccine adjuvants can enhance both the humoral and cellular responses to antigens in some clinical trails. CpG ODN was applied in several clinical trials as an adjuvant of tumor vaccine. CpG ODN alone had anti-tumor activity and had synergistic effects with other anti-tumor therapies including monoclonal antibodies, chemotherapy, radiotherapy, cytokines, etc. Compared with standard regimen, in the phase Ⅲ clinical trial CpG ODN did not prolong the median survival time and induced severe adverse reaction in the treatment of ⅢB-Ⅳ stage non-small cell lung cancer. But CpG ODN had definite anti-cancer activity in other clinical trials. The safety and efficacy of CpG ODN in anti-tumor therapy needs to be further verified in clinic.

The efficacy of acupuncture for pain diseases is significant, however, the unified understanding re garding mechanisms of acupuncture analgesia has not been fully reached. In this paper, it is believed that uncoordi nated muscle movement is one of the important causes for pain, while acupuncture could enhance the contact of nerve cells and improve the synergy of muscle movement, so as to achieve the aim of pain relief and even cure.

BACKGROUND: Abnormal curvature of the cervical spine reflects in large measure the degenerative changes of the cervical vertebrae. OBJECTIVE: The effect of manipulative therapy has been recognized in restoring normal cervical curvature, and aimed to further probe into the effect of this therapy on blood flow velocity in the vertebrobasilar arteries of patients with cervical spondylosis. DESIGN: A non-randomized and controlled concomitant study. SETTING: Departments of Spinal Orthopaedics and General Sugery of a University hospital, and the Outpatient Department of Orthopaedic Institute of a college of Traditional Chinese Medicine. PARTICI PANTS: From January 1999 to December 2001, 60 patients with cervical spondylosis were treated in the Department of Spinal Orthopaedics in Ruikang Hospital, Third Department of Surgery, First Affiliated Hospital of Guangxi College of Traditional Chinese Medicine, and Outpatient Clinic of Institute of Orthopaedics, Guangxi College of Traditional Chinese Medicine. The patients were divided into spondylosis group with abnormal curvature(30 cases) and spondylosis group without normal curvature(30 cases) . Thirty healthy subjects were also included to serve as the control group.METHODS: Manipulation was applied in these patients and the cervical curvature and blood flow velocity in the left vertebral artery (LVA) and right vertebral artery(RVA) as well as in the basilar artery(BA) were measured before and after the treatment for comparison. The correlation coefficients between them were also calculated.MAIN OUTCOME MEASURES: ① The cervical curvature before and after manipulation in spondylosis group and control group; ② The blood flow velocity in maximal systolic phase and end-diastolic phase in the specified arteries.RESULTS: The blood flow velocity in maximal systolic phase and end-diastolic phase decreased in LVA, RVA and BA in patients with abnormal cervical curvature, whose blood velocities in maximal systolic phase in these arteries was less than those in control subjects and patients with normal curvature ( P ＜ 0.05). After manipulation, the velocity in these arteries in creased apparently in patients with abnormal curvature. The changes in systolic velocity in LVA and systolic in BA were correlated to the curvature before manipulation, and after that, the maximal systolic velocity in LVA,maximal systolic velocity in RVA and BA were all related to the changes of the cervical curvature. CONCLUSION: Abnormal cervical curvature is the anatomical basis for abnormalities of the vertebrobasilar arteries. Manipulative therapy can restore the cervical curve and blood flow velocity in these arteries.

Objective To evaluate the effectiveness of discharge planning and home care for patients with peritoneal dialysis (PD).Methods A total of 60 PD patients were randomly divided into the intervention group and control group,30 cases in each group.Discharge planning and home care were carried out in the intervention group, while routine nursing and telephone follow -up service after discharge were implemented in the control group.The patientsˊscores of Zung Self -Rating Anxiety Scale(SAS),Self -Rating Depression Scale(SDS),Self management ability of patients undergoing peritoneal dialysis,complication rate and readmission rate were compared between the two groups at the next day admission,discharge,lth month and 3th after discharge.Results The scores of SAS and SDS in the intervention group were significantly lower than that in the control group at 3th month after discharge,the difference was statistically significant(tSDS =5.263,tSAS =3.812,P <0.05).The Self management ability of patients undergoing peritoneal dialysis was significantly higher than that of the control group at lth and 3th month after discharge,the difference was statistically significant (t =6.845,t =7.231,P <0.05).No significant difference in the re -admission rate (16.67%,6.67%)was found between the two groups (χ2 =0.387,P >0.05).The complication rate in the intervention group was significantly lower than in the control group at 3th month after discharge(χ2 =5.124,P <0.05).Conclusion Discharge planning and home care can effectively relieve depression and anxiety in patients with peritoneal dialysis and improve the abilities of daily life.It is worth promoting and applying in clinic.

Objective To investigate the correlation between the stroke-related risk factors and carotid stenosis lesions of ≥40 year′s old Han and minority populations in a community in Beijing as well as the clinical value of carotid ultrasound screening. Methods An investigation of risk factors for stroke and the results of carotid artery ultrasound screening in 510 cases (≥40 years old) Han population and 243 minority population in a community in Minzu University of China in Beijing in April 2014 were analyzed. Results (1)The prevalence of hypertension of the Han population was significantly higher than that of the minority population (53. 5% [n=273] vs. 44. 4% [n=108]; χ2 =5. 43,P=0. 02). (2) The detected rate of carotid intima-media thickness ( IMT ) of the Han population was higher than that of the minority population (77. 5% [n=395] vs. 69. 1% [n=168]; χ2 =6. 03,P=0. 01). There was no significantly difference in the detected rates of carotid plaques and carotid artery stenosis between the two groups (χ2 =0. 56,1. 13 respectively,all P>0. 05). (3) Hypertension and smoking were the independent risk factors for carotid-intima thickening in Han population ( hypertension:OR,1. 851;95% CI 1. 213-2. 825; smoking:OR,2. 311;95% CI 1. 065-5. 016;all P<0. 05). Hyperlipidemia was an independent risk factor for carotid artery intima-media thickening in the minority population (OR,2. 586;95% CI 0. 952-8. 694,P<0. 01). Conclusion To investigate the risk factors for stroke in minority population in China are of particular importance for the prevention of carotid atherosclerotic disease. Carotid ultrasound examination is an important diagnostic technique for early detection of carotid atherosclerotic disease.
