Objective To probe the effect of nursing interventions on depression of patients with acute stroke.Methods 72 cases of stroke patients with depression screened by Hamilton depression scale (HAMD)were divided into the intervention group and the control group with 36 cases in each group.The control group received routine treatment.The intervention group wag given nursing intervention based on routine treatment.The effect was assessed before and after 3,6 and 12 months of intervention with Zung self-rating depression scale(SDS)and improved Rankin scale(MRS). Results The value of SDS after 3,6 or 12 months was significantly lower than that of the control group(P＜0.05),and the value of MRS was significantly higher than that of the control group(P＜0.05).Conclusion Nursing intervention can reduce depression in patients with post-stroke depression.

Objective To explore the occupational stressors and the coping strategies in the newly-employed nurses and to explore their relationships. Method The survey was done among 193 registered nurses with less than 3 years working experience using the occupational stressor scale for Chinese nurses, the simplified coping strategies questionnaire and a self-designed general demography form. Results The total score on occupational stressors was 2.27 ± 0.56, which was at a common level. Postive and negative coping style were 1.88 ± 0.44 and 1.04 ± 0.51. The stressors together with the dimensions were positively correlated with negative coping strategies (P<0.05). Conclusion Nursing administration should improve work environment, provide enough manpower for patient care, carry out training system to focus on education for newly employed nurses, and provide advice and help for them when they need.

Another 192 probationers from August 2009 to July 2010 were assigned as the experiment group,and given clinical teaching by way of the Responsibility Contracting System.The teaching effects in the two groups were compared.Results The probationers in the experiment group had significant improvements in the ability to perform health education,manipulation of nursing skills,ability in observation skills,and nursing documents writing,compared to the control group(P<0?01).Conclusions The teaching mode of responsibility contracting system is effective in strengthening the responsibility of probationer nurses,attaching great importance to the implementation of basic nursing,improving students’ability in implementation of health education and performance of skill manipulation and nursing,and eventually improving the level and quality of nursing teaching?

Objective To study bacterial conditions in amniotic cavity of the third trimester and the delivery. Methods Patients underwent cesarean section due to various reasons were randomly enrolled in the study. Ten ml aqua amnii taken from using aspesis were cultured and the bacteria were identified and tested for drug sensitivity. All patients were not treated with antibiotics before and during operation,conventional antibiotics treatnent was used after operation. The patients were divided into 3 groups based on their status: 34 cases of premature rupture of membrane ( PROM ), thirty-four cases of labor without PROM, and 27 cases of pregnancy without PROM. The positive rate, species , distribution and drug sensitivity of bacteria in the 3 groups were analyzed. Results The positive rate was 61.8% (21/34) in PROM ,52. 9% ( 18/34 ) in labor without PROM,11.1% (3/27)in pregnancy without PROM. The positive rates were significantly different among the 3 groups (x2 = 17.29 ,P =0.000). However, there was no significant difference between the labor without PROM group and the pregnancy without PROM group ( x2 = 0.541 , P = 0.462 ). Staphylococcus epidermidis was the most common isolated bacteria, following by staphylococcus aureas, streptococcus, colon bacillus, and pseudomonas. There were no significant differences of bacterial species between labor without PROM and pregnancy without PROM( x2 = 11.9,P =0.535 ). The relative higher positive rate in the labor without PROM and PROM indicated that they were important inducement of bacteria infection. There were no significant difference on positive rate and bacteria species distribution between the PROM and labor without PROM group,which suggested that up-bound along vagina to amniotic cavity was the most common route of infection. Sensitive antibiotics should be given to the patients of PROM and labor without PROM targeted at staphylococcus,streptococcus, colon bacillus and monad. Antibiotics such as Cephems, Penicillins and Clindamycin were sensitive to various bacteria and safe to both mother and baby, thus were recommended. Quinupristin, Vancomycin,Furantoin, Fusidic ,Teicoplanin, Amikacin and Meropenem were also sensitive to various bacteria, but due to their side effects and the principle of ladder antibiotics using, they were recommended as second line antibiotics. Conclutions Up-bound along vagina to amniotic cavity is the most common route of infection. For rupture of membrane and labor without PROM patients, antibiotics should be given, and strict aseptic technique,washing cavity and incision, using antibiotics after operation are necessary to prevent infection.

This is a study on the histologic pattern and mechanical properties of tissue-engineered tendon implanted for treatment of tendon defects. Tendons were resected from Roman chickens. Tendon cells were isolated from the tendons and cultured in vitro. The 2nd-4th passages of tendon cells were seeded on the degradable polyglycolic acid mesh to form cell-scaffold composites, which were further cultured for 7-10 days to construct tissue-engineered tendons. The tendon defects, 0.5 cm-0.8 cm in length, were made in the second digit flexor tendon bilaterally in 20 Roman chickens and then bridged with the constructed tissue-engineered tendons. At 2 weeks, 4 weeks, 6 weeks, and 8 weeks post-operation, the samples of regenerated tendons were collected for gross examination, histologic staining and biomechanical test. After implantation of the tissue-engineered tendons, the wounds healed well. The gross appearance, the cells and collagen fibers arrangement of the regenerated tendons were similar to those of natural tendons, but there were relatively not many closely packed collagen fiber bundles organized in parallel with the tendons ("remodel"), so the maximum tensile force increased slowly and its value was 15.40+/-10.63 N at 8 weeks after surgery, reaching only 23% of that of natural tendon. The maximum strain was 22.49%+/-10.21% at 8 weeks, being 10% higher than that of natural tendons. Polyglycolic acid scaffolds are degraded in vivo so rapidly that the regenerated tendons lose the normal biomechanical stimulus and then are unable to be remodeled. As a result, the mechanical strength of regenerated tendons is much lower than that of natural tendons. These results suggest that the normal biomechanical stimulus may be an important factor for the regenerated tendons to remodel.

Experiments have been performed to investigate why the biomechanical strength of repaired tendons is lower than that of the normal tendon when the engineered tendons are implanted in vivo to replace the tendon defects. We seeded the primary culture tendon cells derived from Roman chickens' digital flexor tendons on the degradable polyglycolic acid meshes to construct tissue-engineered tendons. The flexor tendon defects (0.5 cm-0.8 cm) excised in second digit bilaterally in 20 Roman chickens, had been repaired with the constructed tissue-engineered tendons. The samples of repaired tendons were collected at 2, 4, 6 and 8 weeks after operation. Tests for scaffold weight, hydroxyproline content, and mechanical strength of the samples were performed. We found that from 2 weeks to 8 weeks afteroperation, the weight of the scaffolds decreased significantly, almost disappearing at 8 weeks; the hydroxyproline content determining the total collagen content increased gradually without significance; mechanically, both energy at break and tensile strength showed a tendency of drastic decrease at first 4 weeks afteroperation and a gradual increase afterwards, but the tensile strength at 8 weeks afteroperation was only 23% of that of the normal tendon. We conclude that the lower biomechanical strength of repaired tendons is owing to the serious mismatch between scaffold degradation and collagen synthesis.

Objective:To explore the correlation between parents′ posttraumatic growth, mental resilience and family functioning in children with autism spectrum disorder.Methods:Using the convenience sampling method, 169 parents of children with autism spectrum disorders were selected. General data questionnaire, Posttraumatic Growth Inventory (PTGI), Conner-Davidson Resilience Scale (CD - RISC) and Family Assessment Device (FAD) were investigated.Results:The total PTGI score of parents of children with autism spectrum disorder was 58.79±18.92. The scores of appreciation of life, new possibilities, personal strength, relating to others and spiritual change were 19.49±6.15, 10.46±4.59, 9.05±3.32, 7.79±3.65, 12.01±3.83. The PTGI score of 37.3% parents was lower than 52, which was at a low level. Parents in the high score (> 74) group and the low score (< 52) group had statistically significant differences ( P<0.05) in the total score of CD - RISC and scores in all dimensions, as well as the differences in the scores of the four dimensions of FAD, namely problem solving, communication, role and behavior control. The total score of PTGI of parents was positively correlated with the total score of CD - RISC and the scores of its all dimensions ( r values were 0.201-0.317, P<0.05), and negatively correlated with the scores of Problem Solving, Communication and Behavioral Control of FAD ( r values were -0.233 - -0.196, P<0.05). Conclusions:The parents of children with autism spectrum disorder have an average level of posttraumatic growth. People with better mental resilience and healthier family functions have higher post-traumatic growth level.
