Objective To explore the constraint effect of self - made binding sheets to restless patients. Methods Using soft canvas and thick qualitative cotton for sheets making. 100 cases of Neurusurgery JCAHO into patients of level 2～3 were, randomly divided into 52 cases of obeservation group and 48 cases of control group, then use self - made binding sheets and traditional binding sheets respectively for the purpose of protective constraint. Re-sults The interference treatment and skin damage of the observation group, and the psychological pressure of nursing staff were significantly lower than those in control group (P < 0.01). Conclusions With self - made binding sheets the patients have integrity constraints, and the result is better than the traditional one.

Objective: To investigate the psychosocial characteristics and mind-physique status of pa-tients with gynecological malignant tumors. Methods: Clinical psycho-rating scale [life event scale (LES) and symptom checklist-90 (SCL-90)] was applied to test life events and mind-physique status of 60 cases of pa-tients with gynecological malignant tumor. The results were compared with those of 40 female patients with benign tumors and 40 normal females. Results: The frequency and tension value of total life events and those of negative life events in the malignant cancer group were much higher than those in the benign tumor group and normal group (P<0.05) and no remarkable differences were found in the frequency of positive life events among the three groups. The frequencies of total life events and negative life events were higher in the be-nign tumor group than those in the normal group (P<0.05) but there were no significant differences in the fre-quency of positive life events, total tension value or positive tension value among the three groups. No signifi-cant differences were found in the indices of SCL-90, positive scores and scorns of other factors among the three groups (P>0.05). The scores of somatization, obsession, interpersonal relationship sensitivity, anxiety, hostility, phobia, and paranoia were higher in the malignant tumor group than in the benign tumor group and normal group (P<0.05). The average positive scores and the depression scores in the benign tumor group were higher than those in the normal group (P<0.05), but there was no statistical significance in other indices between the benign tumor group and the normal group (P>0.05). Conclusion: Negative psychosocial factors are closely correlated with the occurrence and growth of gynecological malignant tumors. Active psychological intervention should be performed as eady as possible.

Objective To establish rat models of polycystic ovary syndrome(PCOS) induced by different methods,to assess the serum levels of several related hormones,to examine the morphological changes in the ovaries,and to discuss their significance.Methods Letrozol,sodium prasterone sulfate,or sodium prasterone sulfate combined with human chorionic gonadotropin were used to establish rat models of PCOS.Radioimmunoassay was used to measure the serum levels of hteinizing hormone(LH),follicle-stimulating hormone(FSH),estrogen(E_2),progesterone(P),testosterone(T),prolactin(PRL),and insulin(INS).HE staining was used to examine the morphological changes of the ovaries.Results Comparing with the normal group A,the serum FSH was increased and the serum progesterone was reduced in the group B,with a statistically significant difference(P<0.05).The serum testosterone was significantly higher in the group B than in the group A(P<0.01).The levels of serum sex hormones and insulin were not significantly different in the group D and C(P>0.05).In comparison with the group C,the levels of serum testosterone and LH/FSH ratio was significantly increased in the group E.(P<0.05).Comparing with the group D,the serum levels of progesterone and testosterone were significantly increased in the group E(P<0.05).The ovaries in the rats of groups A and C showed almost a normal histyology,with mature follicles and dominant follicles.Polycystic changes were observed only in the ovaries of groups B,D and E.Conclusion At the aspect of affecting the level of sex hormones in serum and changing the ovarian morphology.adopting letrozol tablets or sodium prasterone sulfate combined with HCG to induce rat PCO model is more close to clinic manifestations and meets the criteria of PCO animals.In the rat PCOS models induced with letrozol or with sodium prasterone sulfate combined with HCG,either the serum levels of sex hormones and ovarian histology are quite similar to those of human clinical appearance,and may well meet the modeling requirements for future experimental studies of polycystic ovary syndrome.
