As a clinical diagnosis and treatment of low back pain,straight leg raising test has been used most commonly more than 100 years.It is simple and practical,and has a high clinical value.As a very mature orthopedic special examination,straight leg raising test progress in non-orthopedic applications more often than orthopedic aspects.Of course,the most important thing is the diagnosis of low back pain,followed by the treatment of low back pain,and then can be used as a respiratory and circulatory aspect of diagnosis and treatment options.This article elaborated the principle of straight leg raising test and the clinical research progress in order to give the clinician some guidance.

Objective To investigate the effects of acceptance and commitment therapy on postoperative psychosocial adaptation in breast cancer patients. Methods 120 breast cancer patients were divided into two groups by random number table:58 cases in the observation group and 62 cases in the control group. They all received routine nursing care and the observation group also received acceptance and commitment therapy intervention, including acceptance, cognitive diffusion,being present, self as context, values and committed action. Psychological and Social Adaptation Questionnaire for Breast Cancer Patient (PSAQ-B) was used to investigate their psychosocial adaptation before and after the intervention. Results The intervention group was observed in patients with anxiety/depression, self-esteem and self-acceptance, attitude, sense of belonging, self-control and self-efficacy score was respectively (30.14 ± 5.08), (31.68 ± 5.77), (30.03 ± 5.35), (33.68 ± 5.56), (32.86 ± 5.63) points, the control group were (23.75 ± 3.68), (28.87±4.86), (26.12 ± 4.53), (29.18 ± 5.26), (29.06 ± 4.75) points, the difference between 2 groups was statistically significant (t = 6.016- 6.540, all P < 0.05). Conclusions Acceptance and commitment therapy can effectively improve the psychosocial adaptation status in breast cancer patients after surgery to help improve their quality of life.

Objective: To establish an experimental model of atherosclerosis in rats and to study the atherosclerotic lesions in the aorta,heart and liver.Methods: The rats in experimental groups were injected with a single dose of vitamin D (600 000 IU/kg) and loaded with high fat diet;control group was given saline and basic food.The pathological changes were observed in the aorta,heart and liver after 2,4,6 weeks.The scores were evaluated according to the pathological degrees.Results: No changes were observed after 2 weeks,but after 4 weeks atheroslerotic plaques were seen in the aorta and the score of the lesions were 0.50?0.39; a little lipid were found in coronary arteries;deposition of lipid was seen in the myocardium; many positive red pellets were found in the plasma of cells in the liver.After 6 weeks,more atheroslerotic plaques were observed in the aorta,and atheroslerotic plaques in coronary arteries were formed (pathological score 1.12?0.48); abundant positive red pellets were found in the plasma of the cardiac myocyte.The pathological changes occurred in rats were very similar to that of man.Conclusion: The experimental model of atherosclerosis in rat may be conveniently established by injection of vitamin D with loading of high fat diet,which can be used for the pathological and pharmacological study of atherosclerosis.

Many studies have shown that chronic inflammation occurs in the brain of patients with Alzheimer's disease (AD). It is well known that long-term administration of non-steroidal anti-inflammatory drugs (NSAIDs) can alleviate the cognitive decline of AD patient and elderly. Several inflammatory cytokines produced in the metabolism of arachidonic acid (AA) are closely related to inflammatory diseases. Lipoxygenases (LOXs) and cyclooxygenases (COXs) play a crucial role in the AA network, the products eicosanoids have an important impact on the progression of AD. Although there are many arguments and conflicting evidence, currently LOXs and COXs are still the hot topics in the research on AD pathogenesis and drug development. Here, we review the progress in research on COXs and LOXs, including their actions on CNS and their association with AD, and explore the feasibility of LOXs and COXs as targets for the drugs to prevent and/or treat AD.

This study is to investigate the protein and mRNA expressions of pro-inflammatory and anti-inflammatory cytokines in U937 foam cells and effects of Ginkgo biloba extract (GbE) on the cytokines.U937 cells were cultured with different concentrations of GbE (0.1,1,and 10 μg·L-1),and stimulated by 100 mg·L-1 oxidized low density lipoprotein (ox-LDL) for 24 h.The expressions of interleukin-1β (IL-1β),tumor necrosis factor-α (TNF-α) and interleukin-10 (IL-10) in culture solution were detected by enzyme-linked immunosorbant assay (ELISA) and reverse transcriptase polymerase chain reaction (RT-PCR).The results showed that incubated with 100 mg·L-1 ox-LDL for 24 h,the U937 cells became foam cells,the protein or mRNA expressions of IL-1β,TNF-α,IL-10,and its receptor IL-10R in U937 foam cells were higher markedly than those in normal U937 cells.When the cells were pretreated with GbE (0.1,1,and 10 μg·L-1),the increases of IL-1β and TNF-α in U937 foam cells were remarkably inhibited,but IL-10 expression increased greatly.Especially when cells were pretreated with 10 μg·L-1 GbE,the protein and mRNA expressions of IL-1β and TNF-α were markedly lower than those in U937 foam cells.The protein expression of IL-10 and mRNA expressions of IL-10 and its receptor IL-10R were markedly higher than those in U937 foam cells.GbE inhibited production of pro-inflammatory cytokines IL-1β and TNF-α,but up-regulated the production of anti-inflammatory cytokine IL-10 and its receptor IL-10R in U937 foam cells,which might be related with its anti-atherosclerotic actions.

ObjectiveTo study HIV-1 DNA levels in different parts of HIV patients during the early stage of antiretroviral therapy.MethodsThe peripheral blood,gut associated lymphoid tissues and lymph nodes samples were collected before and 12 weeks after treatment in regular follow-up HIV-1/AIDS patients in Beijing Youan Hospital ( n =11 ).The average age was 39 years old ( 25 to 55 ).Mononuclear Cells were isolated by density gradient centrifugation and then used DNA extraction kit to extract DNA.Realtime quantitative polymerase chain reaction was used to examine HIV-1 DNA copy-number.Non-parametric test was used to analyse the differences of HIV-1 DNA copy numbers among groups.Results Before treatment,HIV-1 DNA copy-number in both gut associated lymphoid tissues ( 10 714 ± 2043 ) copies/106 cells and lymph nodes (9145 ± 1202) copies/106 cells were higher than that in the peripheral blood (66 ± 8) copies/106 cells ( U =0.00,P ＜0.05 ),There was no significant difference between lymph nodes and gut associated lymphoid tissues (U =46.00,P ＞0.05).After 12 weeks of treatment,HIV-1 DNA copy-number in both gut associated lymphoid tissues (1701 ± 790) copies/106 cells and lymph node (11 591 ± 1781 ) copies/106 cells were higher than the peripheral blood ( 18 ± 3 ) copies/106 cells ( Z =- 2.934,P ＜ 0.05 ).There was a significant reduction of DNA copy-number in gut associated lymphoid tissues and peripheral blood after treatment (Z =- 2.934,P ＜ 0.05 ).Conclusion Gut associated lymphoid tissues and lymph nodes may be important latent reservoirs for HIV-1 DNA.

OBJECTIVE:To evaluate the effects of clinical pharmacists participating in disease management of chronic heart failure(CHF). METHODS:A total of 180 CHF inpatients selected from cardiovascular medicine department of our hospital during Jan. 2013 to Dec. 2014 were divided into control group and pharmacist management group according to random number table,with 90 cases in each group. The control group was given routine treatment. The pharmacist management group additionally received indi-vidualized pharmaceutical care,such as pharmaceutical monitoring,psychological counseling,medication education and 6-month follow-up. The comprehensive self-care ability of the 2 groups were compared on admission and on discharge;re-hospitalization and mortality were compared between 2 groups within 6 months after discharged;the patients’NYHA classification,LVEF,plas-ma level of NT-proBNP and quality of life were compared between 2 groups on admission and 6 months after discharge. RE-SULTS:There was no statistical significance in the cognition of patients to disease,self-care ability,medication compliance score and total comprehensive self-care ability score between 2 groups on admission (P>0.05). Each score and total score of 2 groups were better on discharge than on admission,and the pharmacist management group was better than control group,with statistical significance(P<0.05). Within 6 months after discharge,re-hospitalization rate of pharmacist management group was significantly lower than that of control group,with statistical significance (P<0.05). There was no statistical significance in mortality rate be-tween 2 groups (P>0.05). There was no statistical significance in NYHA classification,LVEF,plasma level of NT-proBNP be-tween 2 groups on admission(P>0.05). 6 months after discharge,the above 3 indexes of pharmacist management group as well as NYHA classification and plasma level of NT-proBNP of control group were improved significantly compared to on admission;NYHA classification,LVEF and plasma level of NT-proBNP of pharmacist management group were better than those of control group at corresponding period,with statistical significance (P<0.05). There was no statistical significance in social limit,mood, symptom score and total score of life quality between 2 groups on admission(P>0.05). 6 months after discharge,each score and total score of 2 groups were all better than on admission,and the pharmacist management group was better than control group, with statistical significance (P<0.05). CONCLUSIONS:The participation of clinical pharmacists in the disease management of CHF can significantly improve comprehensive self-care ability,decrease re-hospitalization rate,ameliorate cardiac function and en-hance the quality of life.
