Objective To investigate the status of orthopedic rehabilitative nursing care. Methods A self-designed questionnaire on the orthopedic rehabilitative knowledge and orthopedic rehabilitative care was used to investigate 250 nurses in the orthopedics department of 10 hospitals. Results 62.45% of the 250 nurses passed the knowledge questionnaire. Nurses comprehended the basis knowledge on orthopedic rehabilitative more than the clinical knowledge; the physiological nursing care of orthopedic rehabilitative was the best, communication with patients' family members was better, and nurses payed few attentions to daily living care, psychological nursing care and following-up after the patients were discharged. Conclusions The clinical knowledge on rehabilitative nursing among the nurses needs timely enhancement, and the work of daily living care, psychological nursing care and following up should be improved.

Objective To clarify the association of age and sun exposure with human epidermal thickness, and to probe deeply into the changes of skin histology and epidermal thickness with skin aging.Methods Two hundreds and eleven full thickness skin samples were collected from 3 different age groups of healthy volunteers and then stained with haematoxylin and eosin to study the changes of epidermal thickness using image analysis software ( Image pro plus 6.0). The obtained values were analyzed with factorial design ANOVA and correlation analysis to detect any significant effects of age and sun exposure on epidermal thickness.Results With increasing age, the junction between epidermis and dermis became flattened, and stratum comeum got looser. There was a notable attrition of the epidermal thickness that could be correlated with age. The at-trition of epidermal thickness attributed to age did not vary between female and male volunteers. Epidermal cell layers thickness increased with cumulated sun exposure, but epidermal total thickness was not associated with sun exposure. There was no difference for epidermal thickness of different sun exposure between female and male volunteers. Conclusion During chronological aging, epidermal cells decrease in thickness with lowered metabolism. With cumulated sun exposure, epidermal cell layer thickness becomes thicker. There is no interaction between the effect of age and sun exposure and the epidermal thickness.

Objective To observe the changes of serum vascular endothelium-cadherin (VE-cadherin) and plasma arginine vasopressin (AVP) in patients with acute brain injury, and to investigate the VE-cadherin and plasma AVP related to brain edema and prognosis following acute brain injury. Method ELISA was used to measure the serum VE-cadherin level and radioimmunoassay was used to measure serial concentration of AVP in plasma of 110 patients with acute brain injury 12 hours and 3 and 5 days after brain injury. The outcome was estimated in combination of clinical manifestation, iconographic findings and Glasgow Outcome Scale (GOS). Results The levels of VE-cadherin and AVP increased significantly over 12 hours after brain injury with reduction of GCS. The severer brain injury resulted in higher levels of VE-cadherin and AVP, and prolongation of peak brain edema (P < 0.01). VE-cadherin levels showed positive correlation with severity of brain edema (r = 0.69, P < 0.01) and prolongation of brain edema (r = 0.70.P < 0.01). AVP levels had positive correlation with severity of brain edema (r = 0.65, P < 0.01) and prolongation of brain edema (r = 0.64, P < 0.01). Furthermore, there were significant increases in VE-cadherin and AVP levels in patients with low GOS groups (P < 0.01). The VE-cadherin and AVP leveb in poor outcome group persistently increased for 5 days after brain injury and were higher than those in good outcome group and normal control group. There were a correlation between VE-cadherin and AVP in patients with acute brain injury (r = 0.75, P < 0.01). Conclusions VE-cadherin and AVP leveb are closely associated with the prognosis of patients after acute brain injury. VE-cadherin and AVP may play pivotal roles in the pathogenesis of brain edema after acute brain injury.

Objectives:This paper evaluates the rationality and feasibility of pharmaceutical price reform in dis-trict public hospitals in Nanjing .Methods:Pharmaceutical expense data before and after pharmaceutical price reform was collected from databases , changes of some major index about expenditures of medical insurance fund was simula -ted.Results:In Jiangning district hospital which had been reformed ,inpatient and outpatient expenses decreased while patient burden rate was the same or changed only slightly .Under the same stimulation , in four other district hospitals which is about to reform , the drug proportion of inpatient and outpatient and outpatient expenses per -time decreased , while inpatient expenses per-time increased .The hospitalization burden rate decreased by 3 .21%, and health insurance expenditure of inpatient accounted for 7 .74%of the whole fund pool .Conclusions:Pharmaceutical price reform reduced patient financial burden;health insurance fund spending increased and needs more attention in order to guard against the fund risk .The structure of pharmaceutical pricing tended to be reasonable and medical technology and medical service was more helpful .Compensation rates of medical insurance weren't equal, and the higher the compensation rates , the more both patient burden and health insurance fund expenditures were .Sugges-tions:It is crucial to eradicate the system of “subsidizing hospitals by charging more medicine fees” by leading the patient to primary medical situation , pushing the implementation of hospital payment reform and uniting of city inte-gration and urban-rural integration in order to ensure scientific development of district public hospitals .
