It has been demonstrated that certain members of cyclophilins (CyP) family are related to tomurigenesis, which might result from the role for Cyp in cell proliferation. Most members of Cyp family express specifically in tumor tissue in contrast to in normaltissue and cancer-brink tissue. It is possible that a novel approach to cancer therapy and diagnosis would be appeared through exploring the relationship between Cyp and tumor.

The experiments were designed to study the relation between endotoxamia and renal insufficiency and the protective effects of RSM on galactosamine-induced acute hepatic failure. The results indicated that galactosamine-treated rats which all accompanied with endotoxamia exhibited significant renal dysfunction (Per, BUN elevated; UV, Ccr, U_(Na)V fell; FE_(H2O), FE_(Na) enhanced). After treatment of RSM, the endotoxemia was reduced while renal functions were improved. It suggested that there was a close relationship between endotoxemia and renal insufficiency. The experiment proved that the endotoxin was an important factor in the occurance and development of HRS. RSM possessed marked preventive and theraputic effects for HRS. In addition, the model of galactosamine-induced hepatic failure could be used to study the pathogenesis, prevention and therapy of HRS simultaneously.

Nuclear factor-?B (NF-?B) is a nuclear transcription factor that regulates the expressions of multiple genes. It can be activated during cerebral ischemia; it is closely correlated with the inflammatory reaction and apoptosis during cerebral ischemia. NF-?B inhibitor ? (I?B?), an important inhibitor factor of NF-?B, can regulate the survival and death of neuron in the ischemia penumbra. Therefore, the inhibition of the degradation of I?B? and the prevention of the activation of NF-?B with drugs or molecular biological methods has become an important approach in study of the effect of NF-?B at present. Recent studies have indicated that I?B? itself may also participate in the regulation of apoptosis.

AIM: To establish the methods for determining borneol,isoborneol,muscone,benzyl benzoate in Shexiang Baoxin Pills. METHODS: Turbomass GC-MS instrument was used;the selective ion was applied for detecting borneol,isoborneol,muscone,benzyl benzoate.DB-5 capillary column(0.1 ?m?0.25 mm?30 m).The column temperature was rose by program from 80 ℃ to 260 ℃;the quantiative ion m/z 95 used for borneol and isoborneal,m/z 238 for musone,m/z 212 for benzyl benzoate;Shexiang Baoxin Pills were diluted with hexane. RESULTS: The linear ranges of borneol,isoborbeol,muscone,benzyl benzoate were within 0.020-20.0 ?g/mL(r=0.999 3),0.024-24.0 ?g/mL(r=0.999 0),0.029-28.8 ?g/mL(r=0.999 1),0.050-50.0 ?g/mL(r=(0.999 2)) respectively.The average recoveries of borneol,isoborbeol,muscone,benzyl benzoate were 97.00%,(96.30%,) 96.85%,98.20%,respectively. CONCLUSION: The method is simple accurate and highly sensitive and suitable for Shexiang Baoxin Pills.

Objective To study the clinical significance of end-tidal carbon dioxide partial pressure (PetCO2 ) during cardiopulmonary resuscitation (CPR) and seek the fixed value according which to decide if we should and when to give up.Methods This was a prospective,observational study.A total of 124 patients with cardiac arrest in or out-of-hospital from may 2003 to March 2009 in emergency department of our hospital were selected.All of them had definite etiological factors.Changes of PetCO2 in 124 cardiac arrest patients during CPR were tracked.Results The gender,age,rescue time in seventy-one patients with the return of spontaneous circulation (ROSC) after endotracheal intubation have a significant difference with that in fifty-three patients without ROSC (P ＜0.01 ).The PetCO2 of the survival were higher than that of patients without ROSC or with ROSC,but finally died (P ＜0.01 ).A fixed point 14.4 mmHg of PetCO2 after 20 minutes' CPR can be used as a reference value to guide CPR or predict prognosis.Conclusions Monitoring PetCO2 during CPR has a predictive value on the success of resuscitation.

Objective: To explore the influence of Aiweixin on cardiocyte apoptosis of myocardial ischemia-reperfusion injury in rats. Methods: Thirty male Wistar rats, 200-250g weight, were divided into 3 groups randomly: sham-operation group, Ischemia-reperfusion injury group (I/R) and Aiweixin preconditioning group, each group had 10 rats. The model of myocardial ischemia-reperfusion injury was established. The protein expressions of Bcl-2, Bax and Caspase-3 were studied by Immunohistch emicalstaining. Results:The protein expressions of Bax and Caspase-3 increased and Bcl-2 decreased signifi cantly (P

Objective To analyze the clinical characteristics and nursing measures of infection in hospital ICU,and to provide the refer-ence for clinical nursing. Methods From January 2010 to June 2013,116 patients with nosocomial infection in surgical ICU were collected as observation group,and 72 patients with nosocomial infection in the surgery were as the control group. The risk factors of nosocomial infec-tion were retrospectively analyzed,and the problems related to nursing were discussed. Results The nosocomial infection rate was 8. 44% in ICU,which was significantly higher than the surgical infection rate(4. 43%) in general ward (P<0. 05). Whether patients in ICU or surgery ward,respiratory and urinary tract infections were the most common site of nosocomial infection. The mortality rate in ICU was 9. 48%,which was higher than that of nosocomial infection in surgical ward (4. 17%),P<0. 05. The nosocomial infections were obviously related to the age of patients,duration of hospitalization,the invasive operation,antibiotic and immunosuppressive agents and disturbance of consciousness in ICU and general wards (P<0. 01). Conclusion The ICU nosocomial infection rate was significantly higher than that in general ward,the main infection sites are respiratory tract and urinary tract,with a variety of factors,the key is to establish the mechanism of prevention and ef-fective nursing strategy.

0.05).The off-pump group had a shorter respiratory support time [(4.8?1.9)h vs(8.9?2.1)h,t=17.453,P=0.000],less drainage volume[(390?152)ml vs(660?111)ml,t=17.173,P=0.000],and required less blood transfusion [(270?77)ml vs(510?144)ml,t=17.861,P=0.000] than the on-pump group.In the off-pump group,3(2.0%)of the 150 patients developed renal function injury that is significantly more than that in the on-pump group [11/140(7.9%),?2=5.407,P=0.020].Conclusions Off-pump CABG is as effective as the on-pump surgery;moreover,it is a better choice for patients with high-risk coronary disease since this technique is superior in reducing respiratory support time,volumes of chest drainage and blood transfusion,and renal function injury.

Purpose: To examine the drug concentration in axillary nodes after regional injection of carboplatin-activated carbon suspension (CP-CH) in patients with breast cancer, and compared the result with what happened after regional injection of carboplatin solution ( CP-Sol). Methods: 32 patients with breast cancer were divided into 2 groups randomly with 16 patients in each group. One group received regional subcutaneous injection of CP-CH adjacent to the primary tumor. The contrast group received CP-Sol under the same conditions. Modified mammectomy was done 1, 12, 24, 72 hours later. The carboplatin concentration in axillary lymph nodes was examined by atom absorbing spectrometry. Results: At 1, 12, 24, 72 hours after injection of CP-CH, the carboplatin concentration in lymph nodes was 11.23?5. 66u,g/g, 26.40?11. 18u.g/g, 18.72?7. 14u.g/g, 15. 44?6. 92u,g/g, respectively. At 1, 12, 24 hours after injection of CP-Sol, the carboplatin concentration was 0. 24? 0. 06ug/g, 0. 13? 0. 08ug/g, 0. 12? 0. 04ug/g, respectively. No carboplatin was found at 72 hours after injection. The differences between the two groups were very significant (P
