ObjectiveTo investigate the children with cerebral palsy (CP) in rehabilitation, their families and need of society support. Methods150 children with CP in rehabilitation participated in this study. A questionnaire was designed to investigate their basic situation, family status, society concern and requirements for society support, which completed by their parents. Results150 questionnaires were completed efficiently. 75 children were firstly treated before 1 year old. The rehabilitation treatments were effective to 130 children. 126 children appeared some disorder in emotion and personality. Home education was the main rehabilitation way in 133 children. The educational background of 59.4% mothers were senior high school or below. The income was less than 60 thousand yuan in 76.7% families, but spent more than 40 thousand yuan per year on treatment in 54.7% families. One or both parents in 119 families were forced to stop working. 93.3% of them suffered emotion pressure and 56.7% lacked the knowledge about CP. 81% families thought that more social support should be offered in 6 aspects including government welfare, social security, medical institutions, psychotherapy, community services and legal aid. ConclusionAll society should pay more attention on the children with CP and provide a good rehabilitation environment for them.

Objective To estimate the expression of ER and PR in the endometrium of both intrauterine adhesions (IUA) and non-IUA specimens. Methods The endometrium specimens from patients undergoing hysteroscopy for confirmed moderate IUA (n=20: 10 in proliferative phase, and 10 in secretory phase) were enrolled as the IUA group in Beijing Obstetrics and Gynecology Hospital from October 2014 to August 2015. The specimens scheduled for hysteroscopy due to infertility were recruited into the control group (n=26: 13 in proliferative phase, and 13 in secretory phase). Immunohistochemistry and quantificational real-time PCR (qRT-PCR) were used to detect the expression of ER-α, ER-β and PR in endometrium with different menstrual period in both groups. Results (1) Location: in both groups, the expression of ER-α, ER-β and PR appeared in the endometrial glandular epithelial cells and the stromal cells of the endometrium. The positive brown granules of ER-α, ER-β and PR appeared mainly in cell nucleus. (2) ER-α and ER-β in the endometrium:the protein expression of ER-α and ER-β in IUA group (proliferative phase: 0.657 ± 0.028, 0.493 ± 0.023; secretory phase: 0.537 ± 0.020, 0.365 ± 0.031) were significantly higher than those of control group (proliferative phase: 0.586 ± 0.025, 0.437 ± 0.022; secretory phase:0.459 ± 0.025, 0.323 ± 0.017;all P<0.01). And the ER-αand ER-βmRNA expressions in IUA group were 2.524 ± 0.296, 1.947 ± 0.339, higher than those of control group in the proliferative phase (all P<0.01), and in the secretory phase (1.977±0.333, 1.345±0.292) were also higher than those in the control group (all P<0.01). (3) PR in the endometrium: the protein expression of PR was not significantly different between IUA group (proliferative phase:0.248±0.025, secretory phase:0.194±0.024) and control group (proliferative phase: 0.234 ± 0.019, secretory phase: 0.186 ± 0.020; P=0.162, 0.359). Meanwhile, there were no statistical differences in the mRNA expression of PR in both groups with different menstrual period (proliferative phase: 1.144 ± 0.384 versus 0.981 ± 0.306, secretory phase: 0.763 ± 0.237 versus 0.631 ± 0.203; P=0.270, 0.166). (4) ER and PR expression in menstrual cycles: the expression of ER-α, ER-β and PR in the IUA group changed with the menstrual cycles, and their expression in the proliferative phase were higher than those in the secretory phase (all P<0.05). Conclusions The expression of ER-α and ER-β in the endometrium of IUA patients changes with menstrual cycle, and are higher compared with those in normal endometrium. No difference is found in the PR expression between the two groups.

Objective To detect the dynamic change of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with major trauma and measure its relation to the outcome.Methods Sixty patients with major trauma were measured with serum NT-proBNP level at 1,3,and 7 days postinjury.According to the prognosis,the patients were allocated to survival group (n =47) and death group (n =13).Changes in NT-proBNP was detected and compared between the two groups.Correlation of NT-proBNP level with acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and ISS was analyzed at each time point.Receiver operating characteristic curve (ROC) was developed to determine the prognostic value of NT-proBNP.Results Overall NT-proBNP level revealed no statistical difference at each time point and kept within normal reference range.NT-proBNP level in death group increased gradually,whereas in survival group the increase was followed by a reduction.Moreover,NT-proBNP level was higher in death group than in survival group at each time point.Area under the ROC of NT-proBNP had no statistical difference with that of APACHE Ⅱ and ISS at each time point.Conclusions Obviously high or continuously increased NT-proBNP level may indicate an unfavorable prognosis of major trauma patients.NT-proBNP can be used as a marker to dynamically predict prognosis of major trauma patients.

Objective To investigate cytotoxicity,biocompatibility and new bone formation traced of Chinese porous tantalum,and provide experimental strategies for further clinical application.Methods The physical properties of the porous tantalum were observed by the SEM.The osteoblasts were isolated from rabbit embryo.The extract fluid from tantalum was made.The cytotoxicity and proliferation of osteoblasts compounded with porous tantalum in vitro were detected by the MTT assay.The osteoblasts were co-cultured with extract of tantalum in vitro and the morphological changes,proliferation and adhesion were observed under SEM.A total of 24 New Zealand rabbits were used to establish the model of femoral condyles with porous tantalum bars implanted.Among which 4 of them was injected with calcein and alizarin on the 5th day and the 19th day and sacrificed at 10 week postoperatively.The specimens were observed with LSCM at 488 nm and 543 nm wavelength respectively.The remained 20 animals were sacrificed successively at 2,4,8,12 weeks of implantation,then were examined by histological observation.Results The SEM showed that the pore of porous tantalum were three-dimensional connected morphology.MTT assay showed that the osteoblasts grew well in extract and no significant difference between experimental and control groups.The osteoblasts grew and spread extensively on porous tantalum.Early on co-culture,the osteoblasts attached to the surface and inner walls of material,in the later stage,the osteoblasts excreted bone matrix over the surface of porous tantalum.The animal model showed that porous tantalum was bonded closely with host bone.Hard slicing showed that new bone and capillary regenerated on tantalum-bone interface at 2,4 weeks postoperatively.The pores were full with bone tissue at 8,12 weeks.The LSCM indicated that the green and red fluorescence-labeled new bone was displayed on tantalum-bone interface,while the red zone located around the green zones.They appeared to be discontinuous at early stage,but connected with each other at the end.Conclusion The Chinese porous tantalum has good biocompatibility and no cytotoxicity.The contact osteogenesis and bone conduction exist in tantalum-bone interface,and in a time-dependent manner.

Objective To explore the effect of group psychological training on the mental health and self consistency of nurses from operating rooms.Methods 52 nurses of an operating room were randomized into the treatment group(n=25)and the control group(n=27): The latter received humane care and instructions for mental self care and the former received group psychological training for 8 weeks based on the same treatment as in the control group.Symptom checklist 90(SCL-90)and self consistency and congruence scale(SCCS)were used to assess and compare the difference of the two groups before and after training.Results The intra-and inter-group comparisons between pre-and post-intervention showed statistical differences in terms of the total score by SCL,interpersonal sensitivity,depression and hostility,total score by SCCS and the score on the subscale of inconsistency between themselves and their experience(all P<0.05 or P<0.01).Conclusion Group psychological training can effectively improve the level of mental health and self consistency of OR nurses and thus can improve the total psychological status of the OR nurses.

ObjectiveTo detect the serum NT-proBNP level in patients with severe trauma 24 hours after injury in order to find the possible correlated factors for the evaluation of the clinical application.MethodsSixty patients with severe trauma admitted to the emergency ICU were enrolled. Serum NTproBNP level was detected 24 hours after injury for comparison between survivors and nonsurvivors. The validity of NT-proBNP for predicting outcome was analyzed by receiver operating characteristic ( ROC )curve. The factors with significant correlation between NT-proBNP level and the length of ICU stay as well as the duration of mechanical ventilation support were determined in those survivors with correlation and stepwise linear regression analysis. These factors included injury severity score (ISS), head abbreviated injury score (AIS), acute physiology and chronic health evaluation Ⅱ ( APACHE I ), Glasgow coma score (GCS), creatine kinase-MB (CK-MB), cardiac troponin-I (cTn-I) and central venous pressure. Results The median NT-proBNP levels were 762 pg/ml (IQR, 400-1131 pg/mL) in nonsurvivors versus 200 pg/ml (IQR, 80-383 pg/mL) in survivors (Z =-3. 972, P ＜0.01 ). The area under ROC curve of NTproBNP was not statistically different to that of ISS and that of APACHE Ⅱ. The best threshold value of NTproBN to predict the outcome was 384 pg/ml ( sensitivity 0. 846, specifity 0. 766). A positive correlation was found between NT-proBNP and the length of ICU stay ( r =0. 32, P ＜ 0. 05 ) as well as the duration of mechanical ventilation ( r =0. 37, P ＜ 0. 05 ) in survivors. Stepwise linear regression analysis indicated there were significant correlations between APACHE Ⅱ, CK-MB and NT-proBNP.ConclusionsSerum NT-proBNP level 24 hours after injury is correlated with the severity and outcome of patients with severe trauma. It may be used as a complementary biomarker for the rapid assessment of the severity of trauma.

Total parathyroidectomy (PTX) can be used to treat secondary hyperparathyroidism (SHPT)in uremic patients,relieving the patient's osteolytic destruction.Complete resection of bilateral parathyroid glands is key to successful operation.Recently,2 patients successfully received surgical treatment,in which carbon nanoparticles suspension injection were used.With the help of carbon nanoparticles suspension injection,all of the 4 hyperplastic parathyroid glands were found successfully.The parathyroid hormone(PTH) was significantly decreased after operations and the clinical symptoms were relieved simultaneously.We conclude that the use of carbon nanoparticles suspension injection is helpful for total parathyroidectomy operation in uremic patients with SHPT,which can protect the normal thyroid and recurrent laryngeal nerve.

Objective Intrauterine adhesions cause serious damage to women′s reproductive health, to establish animal dis?ease mode, pure mechanical damage is the most similar cause to human pathogenesis, that is very necessary to conduct prospective studies. The study aimed to investigate the efficiency and significance of different mechanical damage methods to establish intrauterine adhesions model in rats. Methods 45 female SD rats were randomly( random number table) divided into three groups:pure scratch group (n=15), 2 mm diameter curet was used to scrape endometrial tissue; Incision?suture group (n=15), a longitudinal incision was made in the uterus, a blade was used to scrape endometrial tissue, the incision was then sutured with absorbable thread;Control group ( n=15) , sham operation, then the abdomen was closed after exposed to air for 20 minutes, the uterus were not injured. Endometri?al keratin immunohistochemical staining, Intrauterine AFS score, fi?brosis semi?quantitative score and pregnancy outcomes were observed to compare the injury of the two methods in establishing the model. Results ( 1) The degree of endometrial glandular epithelium keratin staining decreased significantly in both pure scratch and incision?su?ture groups compared to the control group. (2) AFS scores in pure scratch group and incision?suture group[3.0 (2.0-3.8), 5.0 (3.8-8.0)] were higher than control group[0 (0-0)], the difference was statistically significant (P<0.017); Incision?suture group was higher than pure scratch group, but the difference was not statistically significant(P>0.017). Endometrial fibrosis semi?quantitative scores in pure scratch group and incision?suture group[5.0 (4.0-5.3), 6.5 (5.8-8.0)] were higher than control group[0 (0-0)], the difference was statistically significant ( P<0.017);Incision?suture group was higher than pure scratch group, but the difference was not statistically significant (P>0.017). (3) Embryo number in pure scratch and incision?suture group side [0.5 (0-3.3), 0 (0-2.3)] was lower than the normal side [7.6 (6.8-8.0), 8.0 (7.8-9.0)],the difference was statistically significant (P<0.05) Conclusion Pure mechanical damage including pure scratch and incision?suture method to establish IUAs model were feasible. Both of the two methods could help to do research about pathogenesis and pathophysiological mechanisms of IUAs. Incision?suture method maybe can cause heavier fibrosis degree.

Objective:To study the influence of bone morphogenetic protein-7 ( BMP-7 ) on chondro-cyte secretion and expression of type Ⅱ collagen ( Col-Ⅱ) , aggrecan ( AGG ) and SRY-related high mobility group-box gene 9 ( Sox9 ) mRNA in porous tantalum-chondrocyte composites.Methods: The articular chondrocytes were isolated from 3-week-old New Zealand immature rabbits and identified.The 2nd generation of chondrocytes with 1 ×106/mL inoculate concentration was seeded in porous tantalum and divided into 4 groups, and control group ( tantalum/chondrocyte) , 50μg/L BMP-7 group (50μg/L BMP-7/tantalum/chondrocyte) , 100 μg/L BMP-7 group ( 100 μg/L BMP-7/tantalum/chondrocyte ) , and 200 μg/L BMP-7 group ( 200 μg/L BMP-7/tantalum/chondrocyte ) .The proliferation of chondro-cytes was measured by CCK-8 assay.The chondrocyte growth and morphology were observed by scanning electron microscopy ( SEM) .The synthesis of glycosaminoglycan ( GAG) in chondrocytes was tested by dimethyl methylene blue ( DMMB) colorimetric quantification method.Col-Ⅱ, AGG and Sox9 mRNA in chondrocytes were detected by real-time PCR.Results: The chondrocytes were spindle-shaped in 24 hours of primary cell culture and most cells became polygonal shaped in 4 days.The chondrocytes were affirmed by alcian blue, safranin O and Col-Ⅱimmunocytochemistry staining.The result of CCK-8 assay showed that the level of cell proliferation in 100 μg/L BMP-7 groups were higher than those in the other groups ( P<0 .05 ) .The chondrocytes implanted into porous tantalum scaffolds with BMP-7 had better functions, by which cytoplasmic processes developed and extended to the surface and inner of porous tan-talum by SEM observation.DMMB quantitative determination of GAG showed that GAG amount of chon-drocytes in 100 μg/L BMP-7 groups was significantly higher than those in the other groups ( P<0 .05 ) . The expressions of Col-Ⅱ, AGG and Sox9 mRNA in chondrocytes were up-regulated in the experimental groups, compared with the control group and the best effect appeared when concentration of BMP-7 was 200μg/L.(P<0.05).Conclusion:BMP-7/tantalum/chondrocytes composites enhanced in vitro chon-drocyte proliferation and extracellular matrix greatly, and can promote chondrogenic gene expression.
