Objective To investigate the status quo of psychological capital and compassion fatigue in operating room nurses and to analyze the correlation between them.Method One hundred and ninety nurses from an operating room of four First-Class Grade A general hospitals in Beijing were engaged in the investigation by psychological capital questionnaire and compassion fatigue scales.Results The total score on psychological capital was (78.60±8.72) and the total score on compassion fatigue was (111.53 ±9.88).The mental capital was negatively correlated with compassion fatigue (P ＜0.05).Conclusions The psychological capital of the nurses in the operating room is at the middle level and the sympathetic fatigue is at a high level.The higher the psychological capital,the lower the sympathetic fatigue.Nursing administrators can improve the psychological capital of the nurses in the operating room to reduce their sympathy and fatigue so as to improve the level of mental health of nurses in the operating room.

Epilepsy is a complications of brain injury or stroke,and is a common diseases in reha-bilitation or neurology department.Transcranial magnetic stimulation as a classical treatment means for stroke or brain injury,but also can promote the recovery of epilepsy.However,there is no clear clinical re-port for safety of epilepsy patients use both donepezil and transcranial magnetic stimulation .The article re-views the literature.Clinicians maybe provided some help.

Objective To explore the effect of functional electrical stimulation combined with treadmill training and botulinum toxin type A injection on foot-drop and strephenopodia among stroke survivors.Methods Sixty-seven stroke survivors with foot-drop and strephenopodia were randomly divided into an electrical stimulation group (n=23),a conventional treatment group (n =22) and a combined treatment group (n =22).All 3 groups received a 400 U injection of BTX-A and electrical stimulation.After 24 hours,the patients in the conventional treatment group received conventional treatment including a brain protection agent,limb function exercises,gait training,balance training and training in the activities of daily living.The patients in the combined treatment group received that conventional treatment,plus functional electrical stimulation and weight loss training on a treadmill.The patients in the electrical stimulation group received functional electrical stimulation treatment supplementing the conventional treatment.Therapeutic effects were evaluated before and after six weeks of treatment using integral electromyography (iEMS) of the anterior tibial muscle and the lateral head of the gastrocnemius muscle,the co-contraction ratio (CR) during ankle dorsiflexion,the modified Ashworth Scale (MAS),the Berg balance scale (BBS),a functional walking score (FAC),and the active range of motion (AROM) of the ankle in dorsiflexion and eversion.Results After the treatment,significant improvement was observed in all three groups in the average iEMS value of the anterior tibial muscle and the lateral head of the gastrocnemius muscle,the CR in ankle dorsiflexion,and in their MAS,BBS,FAC and AROM results.There was no significant difference among the three groups after treatment in their average iEMS values at the lateral head of the gastrocnemius.The average values of the other indicators were,however,significantly better in the combined treatment group than in the other 2 groups.Conclusion Functional electrical stimulation combined with treadmill training and botulinum toxin type A injection can significantly improve foot-drop,strephenopodia and the walking function of stroke survivors.This combined treatment deserves popularization and application in clinical practice.

OBJECTIVE: To explore the genetic basis of a Chinese pedigree affected with Dyggve-Melchior-Clausen syndrome. METHODS: Whole exome sequencing and Sanger sequencing were carried out to detect potential pathogenic variants associated with the syndrome. The function of candidate variant was verified by Western blotting. RESULTS: A novel homozygous variant, c.1222delG of the DYM gene was detected in the two affected siblings, for which both parents were heterozygous carriers. The variant has caused replacement of Asp by Met at amino acid 408 and generate a premature stop codon p.Asp408Metfs*10. Western blotting confirmed that the variant can result in degradation of the mutant DYM protein, suggesting that it is a loss of function variant. CONCLUSION The homozygous c.1222delG frameshift variant of the DYM probably underlay the Dyggve-Melchior-Clausen syndrome in the two affected siblings. Above findings has enabled clinical diagnosis and genetic counseling for the family.

OBJECTIVETo study the expressions of the androgen receptor (AR) in the normal prostate, benign prostatic hyperplasia and prostate cancer (PCa), and investigate the relationship of AR with prostatic hyperplasia and PCa.

METHODSThe expressions of AR were detected in 15 normal prostate, 20 benign prostatic hyperplasia and 40 PCa samples by immunofluorescent staining, real-time PCR and Western blotting.

RESULTSReal-time PCR and Western blotting revealed no statistically significant differences in the expressions of AR between the normal prostate and prostatic hyperplasia groups (P < 0.05), while immunofluorescent staining exhibited an increase of the expression in the BPH tissues. All the three methods showed that the AR expression was significantly higher in the PCa than in the normal prostate and prostatic hyperplasia groups (P < 0.05), in the well differentiated than in the poorly differentiated tumor, and in the early than in the advanced stage (P < 0.05), but the lowest in the hormone-refractory PCa (HRPC) tissue.

CONCLUSIONThe expression of AR is higher in PCa than in normal prostate and prostatic hyperplasia tissues, and is correlated with the pathological grade and clinical stage of PCa.

BACKGROUND: Amniotic membrane has a unique structure that can block the penetration of certain substances, to ensure normal nutrition supply for the surrounded tissues, and is also characterized by anti-adhesion, good tissue compatibility, mild inflammatory reaction, few fibers and biodegradability. OBJECTIVE: To compare the effects of fresh amniotic membrane and acellular amniotic membrane to prevent adhesion and promote tendon healing during the repair of tendon sheath defects. METHODS: Sixty healthy male leghorn chickens were selected, and the model of tendon injury and tendon sheath defects was established at the third toes. The animal models were then randomly divided into three groups and underwent repair with fresh amniotic membrane (group A), acellular amniotic membrane (group B), and no treatment in control group (group C), respectively. Histological observation and biomechanical analysis of the third toes were performed after repair. RESULTS AND CONCLUSION: (1) Histological observation. Congestive edema and inflammatory response were found in all animals at 2 weeks after repair, but mildest in the group A and severest in the group C. These inflammatory responses gradually alleviated over time in the three groups. At 12 weeks after repair, the new tendon sheath formed in all the animals, which was more mature than that at 4 weeks after repair. The synovial cells on the surface of the tendon sheath were arrayed tidily with dense structure in the groups A and B, but in the group C, the synovial cells were distributed disorderly with loose structure and prominent fibrous tissues. (2) Biomechanical analysis. Tendon sliding distance in the groups A and B was significantly larger than that in the group C at 4, 8, 12 weeks after repair (P < 0.05), but there were no significant difference in the distance between the groups A and B (P > 0.05). At 4 and 8 weeks after repair, the maximum tensile strength was largest in the group A, sequentially followed by group B and group C (P < 0.05), but there were no significant difference among the three groups at 12 weeks after repair (P > 0.05). To conclude, both fresh amniotic membrane and acellular amniotic membrane can promote tendon healing and prevent the adhesion of tendon through tendon sheath reconstruction, but the fresh amniotic membrane is preferred to promote early tendon healing compared with acellular amniotic membrane.

Domain database is essential for domain property research. Eliminating redundant information in database query is very important for database quality. Here we report the manual construction of a non-redundant human SH2 domain database. There are 119 human SH2 domains in 110 SH2-containing proteins. Human SH2s were aligned with ClustalX, and a homologous tree was generated. In this tree, proteins with similar known function were classified into the same group. Some proteins in the same group have been reported to have similar binding motifs experimentally. The tree might provide clues about possible functions of hypothetical proteins for further experimental verification.

Objective: To analyze the trend change of the drowning mortality among children and adolescents in Chongqing, 2012-2021, and to provide suggestion for drowning prevention and control. Methods: Drowning death cases (ICD-10:W65.0-W74.9) among children and adolescents in Chongqing from 2012 to 2021 were derived from Chongqing death registration system. The difference of the drowning mortality between male and female, urban and rural area were compared by Chi square test. The trend change of the drowning mortality between 2012 and 2021 was analyzed by annual percent change( APC ). Results: The mortality and ASMR of drowning among children and adolescents decreased from 9.57/10 5, 9.42/10 5 in 2012 to 2.80/10 5, 2.83/10 5 in 2021 significantly( t=10.93, 10.52, P <0.01). And its APC were -13.15% and 13.06% respectively. The drowning mortality in male was higher than that in female( P <0.05). The drowning mortality in rural area was higher than that in urban area( P <0.05). The mortality of drowning among children aged between 0 and 4 years old, 5 and 9 years old, 10 and 14 years old decreased by 15.30 %,17.80% and 11.40%( APC =-15.30%, -17.80%, -11.40%, t=11.11, 9.22, 5.62, P <0.05). The proportion of drowning in natural water field among children and adolescents accounted for about 80%. Conclusion The mortality of drowning among children and adolescents in Chongqing decreases rapidly. Vulnerable population of drowning includes boys, rural children and adolescents, and children age of 0-14 years old. Comprehensive prevention for drowning should be carried out continuously.

This study aims to mine the transcription factors that affect the genuineness of Codonopsis pilosula in Shanxi based on the transcriptome data of C. pilosula samples collected from Shanxi and Gansu, and then analyze the gene expression patterns, which will provide a theoretical basis for the molecular assisted breeding of C. pilosula. Gene ontology(GO) functional annotation, conserved motif prediction, and gene expression pattern analysis were performed for the differential transcription factors predicted based on the transcriptome data of C. pilosula from different habitats. A total of 61 differentially expressed genes(DEGs) were screened out from the transcriptome data. Most of the DEGs belonged to AP2/ERF-ERF family, with the conserved motif of [2X]-[LG]-[3X]-T-[3X]-[AARAYDRAA]-[3X]-[RG]-[2X]-A-[2X]-[NFP]. Forty-three of the DEGs showed significantly higher gene expression in C. pilosula samples from Shanxi than in the samples from Gansu, including 11 genes in the AP2/ERF-ERF family, 5 genes in the NAC fa-mily, 1 gene in the bHLH family, and 2 genes in the RWP-RK family, while 18 transcription factors showed higher expression levels in the samples from Gansu. GO annotation predicted that most of the DEGs were enriched in GO terms related to transcriptional binding activity(103), metabolic process(26), and stress response(23). The expression of transcription factor genes, CpNAC92, CpNAC100, CpbHLH128, and CpRAP2-7 was higher in the samples from Shanxi and in the roots of C. pilosula. CpNAC92, CpbHLH128, and CpRAP2-7 responded to the low temperature, temperature difference, and iron stresses, while CpNAC100 only responded to low temperature and iron stresses. The screening and expression analysis of the specific transcription factors CpNAC92, CpNAC100, CpbHLH128, and CpRAP2-7 in C. pilosula in Shanxi laid a theoretical foundation for further research on the mechanism of genuineness formation of C. pilosula.
