Objective To investigate the concentration of procalcitonin,C-reactive protein and WBC count for patients with dif-ferent kind of bacterial infection.Methods 49 blood samples and 81 other samples were collected form different patients for bacteri-al culture.Meanwhile,procalcitonin,C-reactive protein concentration and WBC count of those patients were determined to find whether these indicators exhibited any difference between Gram-positive and Gram-negative bacteria infected patients.Results For bloodstream infection,PCT levels in patients with Gram-nagetive bacterial infection were obviously higher than those with Gram-positive infection(P <0.05 ).For other infection,there was no statistical difference among patients′PCT,CRP concentration and WBC count(P >0.05).Conclusion PCT concentration is valuable in the differential diagnosis of blood stream infection caused by Gram-negative and Gram-positive bacteria,but not in local infection infection.

Goal To promote the university student to foster the civilized behavior.Method From September to October,2007,investigate the 615 students of Nursing Department in Our college,in order to know the situations of civilization and manners on campus.Result Amorg the ten big uncivilized behaviors,in the first place is: uncivilized languge,that is,speaking obscene words.The above is the view of 324 students 167 students think that humiliating the small and weak and fighting are the most disgusting behaviors.So how to foster the university student's civilized behavior turns to be a society problem now.Conclusion The coordination of the autonomy and the heternomy can play a better effect during the process of fostering the civilized behaviors.But the autonomy may play a main role in the process.

Alzheimer's disease (AD) is the most frequent type of dementia in elderly,which has been regarded as a neurodegenerative disease.The traditional point of view considers that AD and vascular dementia are two different types of dementias both from their pathogenesis and treatment;however,in recent years,a growing body of evidence indicates that the vascular factors are playing an important role in the development and occurrence of AD.This article reviews cerebral ischemia and its risk factors including the effects of hypertension,diabetes,and cholesterol in the development and occurrence of AD,so as to provide new strategies in preventing,and delaying the occurrence and progression of AD.

OBJECTIVETo observe the effect of Tetramethyl pyrazine (TMP) on the cytokines and inflammatory mediators in the serum and the synovial fluid of collagen-induced arthritis (CIA)rats, and further to investigate its possible mechanisms for treating rheumatoid arthritis (RA).

METHODSType II CIA rat model was established. Rats in the TMP group were administered with TMP at 50 mg/kg and 100 mg/kg, once daily. Dexamethasone at 2.0 mg/kg was intramuscularly injected to those in the Dexamethasone treated group, once daily. Normal saline at 2 mL/kg was given to those in the normal control group and the model group, once daily. All medication was started from the 7th day, lasting to the 35th day. CIA rats' foot swelling degree was observed. Contents of serum IL-1, IL-6, IL-2, NO and PGE2in the synovial fluid were detected by radioimmunoassay and nitrate reduction method.

RESULTSCompared with the normal group, the foot swelling obviously increased, contents of NO and PGE2 in the synovial fluid were obviously elevated in the model group (P < 0.01). Compared with the model group, the foot swelling could be obviously inhibited by 100 mg/kg TMP and Dexamethasone; serum levels of IL-1 and IL-6 obviously decreased, serum IL-2 level obviously increased, contents of NO and PGE, decreased (P < 0.01). TMP 50 mg/kg could obviously inhibit the foot swelling of CIA rats (P < 0.01). There was no statistical difference in other indices (P > 0.05).

CONCLUSIONSTMP at 100 mg/kg showed obvious inhibition on CIA rats. Its inhibitory effect might be correlated to inhibiting activities of endogenous cytokines and the generation of inflammatory mediators in inflammation local regions, improving contents of anti-inflammation cytokines, and inducing the balance of the inflammatory cytokine network.

Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.

Objective To investigate relationship between adiponectin and cardiac damage induced by aldosterone in SD rats. Methods Male SD rats were treated with aldosterone infusion for 4 weeks, systolic blood pressure (SBP) was measured every week. At the end of experiment, the myocardial structure was observed, the levels of adiponectin in plasma and adiponectin mRNA expression of adipose tissue in epididymal fat pad were measured. 3T3-L1 adipocytes treated with 10-8 and 10-6 moL/L aldosterone for 24 and 48 h, adiponectin mRNA expressions and adiponectin concentrations in culture medium were measured. Results Aldosterone induced only a slight increase in the SBP of SD rats[(123±7)mm Hg, P<0.05]. However, aldosterone significantly induced cardiac ultrastructure changes, such as mitochondrial swelling and disordered internal structures. Furthermore, the level of plasma adiponectin decreased 22.8% after aldosterone treatment for 4 weeks ( P<0. 05 ). When 3T3-L1 adipocytes were treated with 10-8 and 10-6 mol/L aldosterone for 24 h, adiponectin concentrations in culture medium decreased 21.8% and 27. 2%, respectively (P < 0. 05); for 48 h, adiponctin mRNA expressions decreased 22.1% and 37.4%, respectively ( P<0. 05 ). The effect of aldosterone was reversed by spironolactone,which was partly independent of SBP. Conclusions Low level of adiponectin may be involved in cardiac damage induced by aldosterone in SD rats.

Objective To explore the effect of liraglutide on pressure?overload chronic heart failure in rats and related mechanisms. Methods Totally 30 SD rats were randomly divided into sham operation group, heart failure group and liraglutide group. The animals were anaesthetized and a Millar pressure volume conductance catheter SPR?838 ) was inserted through right carotid artery into LV to measure pressure?volume ( P?V ) loop. Body and organ weight were measured. After the end of intervention, the rats were anesthetized, and abdominal aortic blood taken from the upper serum after centrifugation. Kit method was used to measure superoxide dismutase (SOD), brain natriuretic peptide (BNP), malondialdehyde ( MDA) . Results Compared with those of the sham operation group, there was a increase in absolute heart weight and (P < 0?05). During the P?V loop analyses, We found that left ventricular (LV) end?systolic volume, end?diastolic volume, end?systolic pressure, end?diastolic pressure and maximum pressure were all remarkablely lower in liraglutide group than HF group in rats ( P < 0?05 ) . Peak rate of pressure rise ( dP/dt max ) , peak rate of pressure decline ( -dP/dt min) , ejection fraction and Maximum Power were increased in liraglutide group comparable by HF group (P < 0?05). SOD activity was significantly increased and BNP concentration was significantly decreased in liraglutide group compared to HF group (P < 0?05). Conclusions These results show that liraglutide protects pressure?overload rat heart from failure possibly through reducing oxidation.
