ObjectiveTo investigate the negative emotions of patients before cardiac surgery in West China Hospital in order to analyze the related factors.MethodsThe Huaxi emotional-distress index (HEI), a screening tool for mood disorders developed by the Mental Health Center of West China Hospital, was used for preoperative psychological evaluation of 1 968 adult patients hospitalized in cardiac surgery from March 2016 to July 2014. There were 835 males and 1 133 females at age of 49±13 years.Results Fifty-one patients (2.6%) had negative emotions, among whom 6 patients were screened for suicide risk. After intervention, none of them had serious consequences caused by adverse emotions, such as automatic discharge from hospital, avoidance of surgery and suicide.ConclusionThis study found that most of the cardiac surgery patients in West China Hospital have good psychological status before surgery, and a few suffered from negative emotions. “Huaxi emotional-distress index” is simple, effective and worth promoting.
Objective
To review the recent advances in the application of graphene oxide (GO) for bone tissue engineering.
Methods
The latest literature at home and abroad on the GO used in the bone regeneration and repair was reviewed, including general properties of GO, degradation performance, biocompatibility, and application in bone tissue engineering.
Results
GO has an abundance of oxygen-containing functionalities, high surface area, and good biocompatibility. In addition, it can promote stem cell adhesion, proliferation, and differentiation. Moreover, GO has many advantages in the construction of new composite scaffolds and improvement of the performance of traditional scaffolds.
Conclusion
GO has been a hot topic in the field of bone tissue engineering due to its excellent physical and chemical properties. And many problems still need to be solved.
Objectives To analyze the effect of sling exercise therapy on the walking ability of children with spastic hemiplegia and cerebral palsy, and to provide a scientific basis for clinical treatment. Methods Children with spastic hemiplegia and cerebral palsy who were treated in the Department of Rehabilitation of Children’s Hospital of Shanghai from July 2018 to July 2019 were selected as the research subjects. The children were divided into conventional treatment group and sling exercise therapy group by random number table method. The routine treatment group was given routine rehabilitation training, and the sling exercise therapy group was given combined sling exercise therapy on the basis of routine treatment. The Gross Motor Function Measure (GMFM)-88-item E functional area score, Clinical Spasticity Index (CSI) and Berg Balance Scale (BBS) score were compared between the two groups. Results A total of 36 children were included, with 18 cases in each group. There was no significant difference in gender, age and hemiplegia side between the two groups (P>0.05). All children completed the trial without adverse reactions. Before treatment, there was no significant difference in BBS, CSI and GMFM-88 E functional area scores between the two groups (P>0.05). After 3 months of treatment, the above scores of the two groups were improved compared with those before treatment (P<0.05). The improvement of the above scores in the sling exercise therapy group after treatment was better than that in the conventional treatment group. The difference of BBS, CSI, and GMFM-88 E functional area scores in the sling exercise therapy group before and after treatment was 8.94±4.15, 2.44±0.71, and 7.28±3.23, respectively, the difference of the above scores before and after treatment in the conventional treatment group was 4.50±4.15, 1.83±0.79, and 2.89±1.64, respectively, and the differences were statistically significant (P<0.05). Conclusion Combined use of sling exercise therapy can better improve the walking ability of children with spastic hemiplegia and cerebral palsy, which is worthy of clinical promotion and application.
Titanium and its alloys have become one of the most widely used implant materials in orthopedics because of their excellent mechanical properties and biocompatibility. Implant-associated infection is the main reason of failure of orthopedic implant surgery. The anti-infection modification of implant surface has received more attention in the field of infection prevention and developed rapidly. This article focuses on the current research status of simple anti-infection surface modifications that make titanium implants possess anti-adhesion, bactericidal activity or antibacterial membrane activity, as well as the research progress of composite functional surface modifications that promote bone integration, osteogenesis or immunomodulatory effects on the basis of anti-infection, so as to provide references for the construction of orthopedic implants with composite functions.

Methods From August 2008 to July 2011, 30 patients with bradycardia arrhythmia underwent temporary cardiac pacemaker implantation surgery. We applied psychological nursing to the patients and made a good preparation of necessary equipments and medicine before operation. During the surgery, all required apparatuses and materials were ready at hand, and careful observation of conditions of the patients was carried out. After operation, the vital signs as well as the development of related symptoms in the patients were closely observed. Results There were 30 patients who had temporary cardiac pacemakers implanted. All got satisfying treatment effects except one who died from severe heart failure combined with inferior-wall myocardial infarction. No intraoperative or postoperative complications occurred, and the patients attained good postoperative recuperation before leaving hospital. Conclusion Temporary cardiac pacemaker is safe and effective in the emergency rescue of patients with severe arrhythmia, in temporary heart protection for patients undergoing renewal of permanent cardiac pacemaker, and in perioperative protection for patients with bradycardia. Good nursing before, during, and after the operation should be guaranteed.
Purpose
To identify the expression of alternatively spliced mRNA isoforms of the NMDA-R1 in the visual cortex of strabismic cats.
Methods
Two pai rs of normal and strabismic cats were used.The amblyopic cats had been made monocularly esotropic (by tenotomy) at the age of weeks,resulting in behavioral am blyopia.Animals were sacrificed about 6 months by intraperitoneal administration of Nembutal.Cryostat sections of fresh,frozen central visual cortex of the ats were cut to 20 micron thickness.A series of digoxygenin-labelled oligonucle otide probes basing on the human gene sequence were used for ISH.Control probes included sense oligonucleotides and short segment probes which were adjacent to ,but did not,span the splice junctions.A computer-assisted systematic morphometric ounting procedure was used to enumerate hybridising cells.
Results
The number of positive cells expressing NMDA-R1 mRNA in t he strabismic amblyopic cats was decreased,notably in layer IV of visual cortex (P<0.0001).The pattern of isoform expression varied between normal and strabismic amblyopic cats with decreased numbers of 1-a,1- b and 1-1 isoforms and apparently increased expression of 1-3 P <0.0001),whereas no significant difference was found for the 1-2 and 1-4 isoforms (P>0.05).
Conclusion
Transcriptional inhibition of NMDA-R1 mRNA and of specifie isoforms may underlie the change in receptor expression.Alternatively,preferentialloss of neurones bearing particular NMDA-R1 isoforms and compensation with a proportional increase in cells expressing other isoforms may occurr during the critical period of visual plasticity.
