Objective To explore the relationship between blood pressure and hemorrhagic cerebral infarction. Methods Retrospectively reviewed clinical data of 242 patients with acute cerebral infarction, then all patients with hemorrhagic cerebral infarction were selected. The distributions of different level of blood pressure (＞180/110mm Hg;90/70～180/110mm Hg;＜90/70mm Hg) were compared between the patients with or without hemorrhagic cerebral infarction, as the same, different prognosis were compared among the patients with hemorrhagic cerebral infarction based on the different level of blood pressure. Results Of the total patients with acute cerebral infarction,4. 1%(10) presented with blood pressure＜90/70mm Hg,88. 0%(213) with blood pressure 90/70～180/110mm Hg and 7.9%(19) with blood pressure＞180/110mm Hg. In all the patients,20 cases(8. 3%) with hemorrhagic cerebral infarction,among which,60.0%(12) patients with blood pressure＞180/110mm Hg and with 7 cases died, 10.0%(2) patients with blood pressure＜90/70mm Hg and with 1 case died,30.0%(6) patients with blood pressure 90/70～180/110mm Hg and with 2 cases died. The distribution of patients with blood pressure＞180/110mm Hg in those two type of cerebral infraction were statistically significant (P=0. 000) ,the ratio seemed higher in patients with hemorrhagic cerebral infarction, and among the patients with hemorrhagic cerebral infarction, the distribution of prognosis were the same statistically significant based on the diffetent level of blood pressure, among which, patients with blood pressure＞180/110mm Hg(P =0.041) or＜90/70mm Hg(P =0.037) seemed like to have a higher mortality. Conclusion Severe high blood pressure(＞180/110mm Hg) should be one of the high risk factors for patients with hemorrhagic cerebral infarction,when blood pressure＞180/110 mm Hg or ＜90/70mm Hg happened in the pathogenesis, patients always be with poor outcome. So, making proper control strategy of blood pressure for patients with hemorrhagic cerebral infarction was with significance to defend its' happening and prognosis' improvement.

Objective To investigate the clinical significance of serum P-selection,TNF-α,hs-CRP,IL-1β, ICAM in patients with diabetic renal microangipathy, and the therapeutic mechanism of Simvastatin combined with aspirinon in treating renal microangipathy. Methods The serum levels of P-selection,TNF-α, hs-CRP, IL-1β, ICAM were determined by ELISA in all groups. Patients with diabetic renal microangipathy treated with simvastatin and as-pirinon. Results ① The serum levels of P-selection,TNF-α,hs-CRP,IL-1β,ICAM in DM groups were higher than those of normal controls(P<0.01). ②After treatment with simvastatin and aspirinon for 8 weeks in patients with di-abetic nephropathy,the serum levels of P-selection, TNF-α, hs-CRP, IL-1β, ICAM were all decreased significantly compared with those before treatment respectively (P<0.01). After treatment for 16 weeks the above indices re-mained decreased until treatment for 21 weeks (P<0.01). Conclusion ①The plasma levels of Poselection,TNF-α and hs-CRP, IL-1β, ICAM are correlated to the occurance and development of diabetic renal microangiopathy, becom-ing predicted factors in early stage of diabetic renal microangiopathy. ②The therapeutic mechanism of simvastatin and aspirinon in patients with diabetic nephropathy lies probably in the inhibition of these factors expression, thus di-rectly or indirectly affecting the prolffer-ation of mesangial cells and mesangial matrix.

Objective To investigate professional identity and its influencing factors in nursing students during late period of clinical practice,which may be helpful for carrying out clinical nursing teaching.Methods General information and professional identity questionnaires were used for investigation in 233 nursing students of late period of intership.Results Sense of professional identity was in the general level (86.00±8.08) points.Employment situation was the main concern for students to choose nursing profession.The professional identity score of professional knowledge and skills were 15.90 and 20.88 respectively in undergraduate students,which were lower than those of college students and secondary specialized school students.Conclusions Nursing educators should pay attention to the guidance and training of professional identity in nursing students,which may contribute to the development of the nursing profession.

Objective To investigate the effect of warm needling on learning and memory abilities and the calmodulin kinaseⅡ (CaMKⅡ) content of prefrontal cortex area in morphine withdrawal rats andexplore the mechanism of its action. Methods Forty clean-grade male SD rats were randomly allocated to control, model, manual needling and warm needling groups, 10rats each. A SD rat model of morphine addiction and withdrawal was made by dorsal subcutaneous injection of day-by-day incremental morphine and rapid withdrawal with Naloxone after addiction. Learning and memory abilities were tested using a Morris water maze and the CaMKⅡ content of prefrontal cortex area was measured by an immunohistochemical method in every group of rats.Results There were statistically significant differences in mean platform escape latency, the number of platform crossing and the CaMKⅡ content of PFC area between the control, manual needling or warm needling group of rats and the model group (P<0.01). There were statistically significant differences in mean platform escape latency, the number of platform crossing and the CaMKⅡ content of PFC area between the warm needling and manual needling groups (P<0.05).Conclusions Warm needling treatment can restore learning and memory abilities in morphine withdrawal rats. The mechanism of its action may be related to an increase in the CaMKⅡ content of prefrontal cortex area.
