ABSTRACT
Recent omic studies prioritised several drug targets associated with coronavirus disease 2019 (COVID-19) severity. However, little evidence was provided to systematically estimate the effect of drug targets on COVID-19 severity in multiple ancestries. In this study, we applied Mendelian randomization (MR) and colocalization approaches to understand the putative causal effects of 16,059 transcripts and 1,608 proteins on COVID-19 severity in European and effects of 610 proteins on COVID-19 severity in African ancestry. We further integrated genetics, clinical and literature evidence to prioritised additional drug targets. Additional sensitivity analyses including multi-trait colocalization and phenome-wide MR were conducted to test for MR assumptions. MR and colocalization prioritized four protein targets, FCRL3, ICAM5, ENTPD5 and OAS1 that showed effect on COVID-19 severity only in European ancestry and one protein target, SERPINA1, only showed effect in African ancestry (odds ratio [OR] in Africans=0.369, 95%CI=0.203 to 0.668, P=9.96x10-4; OR in Europeans=1.021, P=0.745). One protein, ICAM1, showed suggestive effect on COVID-19 severity in both ancestries (OR in Europeans=1.152, 95%CI=1.063 to 1.249, P=5.94x10-4; OR in Africans=1.481, 95%CI=1.008 to 2.176; P=0.045). The phenome-wide MR of the prioritised targets on 622 complex traits identified 726 potential causal effects on other diseases, providing information on potential beneficial and adverse effects. Our study prioritised six proteins as potential drug targets for COVID-19 severity. Several of them were targets of existing drug under trials of COVID-19 or related to the immune system. Most of these targets showed different effects in European and African ancestries, which highlights the value of multi-ancestry MR in informing the generalizability of COVID-19 drug targets across ancestries. This study provides a first step towards clinical investigation on COVID-19 and other types of coronaviruses. Research in contextO_ST_ABSEvidence before this studyC_ST_ABSWe searched key terms in PUBMED published before Feb 1st 2022, with the terms: ("COVID-19, "coronavirus") AND ("omics" or "protein" or "transcript") AND ("Genome-wide association study" or "Mendelian randomization"). We found multiple studies identified targeted genes or proteins associated with COVID-19. However, there is little human genetics evidence support the ancestry-consistent or ancestry-specific genes/proteins associated with COVID-19. Added value of this studyTo our knowledge, this is the first comprehensive genetic study that identified protein targets that showed effect on COVID-19 severity in European and African ancestries. Our study identified one protein, SERPINA1, that showed effects on COVID-19 in African ancestry (OR=0.369, P=9.96x10-4), but not in European ancestry (OR=1.021, P=0.745). In addition, our study identified four additional protein targets, FCRL3, ICAM5, ENTPD5 and OAS1, that showed effect on COVID-19 severity in Europeans. One protein ICAM1 showed suggestive effect in both ancestries. Some of these proteins are related to the immune system and/or are targets of existing drug under trials of COVID-19. Implications of all available evidenceOur study prioritised six drug targets for COVID-19 severity, five of them showed different effects in European and African ancestries. This suggested that drug targets may have different responses on COVID-19 severity in different ancestries. Our study also highlights the value of intercellular adhesion molecule (ICAM) family in relation with COVID-19 severity in both ancestries.
ABSTRACT
Objective@#To evaluate the therapeutic effect of mouse nerve growth factor (mNGF) combined with conventional rehabilitation training on children with cerebral palsy (CP).@*Methods@#According to the inclusion criteria, 60 children with CP(spastic diplegia) who were treated at the Third Affiliated Hospital of Jiamusi University were selected by double-blind method from June to December in 2016.Sixty children with CP were stratified according to age, gender and Gross Motor Function Classification System (GMFCS) (the subjects were classified into 2 age groups: 0-2 years old and 2-4 years old), and then they were randomly divided by draw method: the control group received routine rehabilitation; the experimental group received mNGF additionally.The children with CP in the experimental group were treated with 18 μg mNGF every day for 10 days and then discontinued for 5 days, with 20 injections per month for 1 course, a total of 3 courses.After 3 courses of treatment, the changes in Gesell Development Diagnosis Schedules (GDDS), Peabody Developmental Motor Scales-Gross Motor (PDMS-GM), Peabody Developmental Motor Scales-Fine Motor (PDMS-FM) and Range of Motion (ROM) of the lower extremity were compared between the 2 groups.@*Results@#After 3 months of treatment, the changes of Gesell(gross motor: 57.40±18.13, 44.87±10.95; fine motor: 64.83±18.04, 62.60±17.34; adaptability: 76.07±14.99, 70.57±11.19; language: 74.20±15.07, 71.23±13.38, personal-social interaction: 67.40±14.10, 61.40±12.96), PDMS-GM(94.33±16.03, 81.13±20.15), PDMS-FM scores(91.53±19.73, 91.10±15.84) and ROM[adductors angle: left (69.67±22.2)°, (49.17±21.82)°; right (69.83±21.63)°, (49.67±21.61)°; popliteal angle: left (160.08±30.02)°, (125.50±25.78)°; right (160.17±22.46)°, (126.00±25.31)°; dorsal flexion angle of foot: left (10.17±6.09)°, (4.33±7.28)°; right (9.83±6.23)°, (4.83±7.48)°] in the experimental group and the control group were all significantly higher than those before treatment, and the differences were statistically significant (all P<0.05). After 3 months of treatment, the Gesell gross motor(57.40±18.13) and PDSM-GM scores(94.33±16.03) in the experimental group were significantly higher than those (44.87±10.95, 81.13±20.15, respectively) in the control group, and the differences were statistically significant (all P<0.05).@*Conclusions@#Conventional rehabilitation therapy combined with mNGF has more significant effect on the development and motor function of children with CP than routine rehabilitation training.
ABSTRACT
Objective@#To explore the prediction of weight loss to the function 1 month after surgery in head and neck cancer (HNC) patients with surgical treatment.@*Methods@#During August to November 2017, 122 HNC patients from a tertiary hospital in Chengdu were included and investigated by the General Information Questionnaire and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30.@*Results@#1 month after surgery, the function scores of HNC patients ranged from 86.67(73.33, 93.33) to 100.00(100.00, 100.00), and the physical function score was the lowest. Patients with weight loss during hospitalization had lower score in physical, role and social function (P<0.05). According to the results of Logistic regression analysis, age (OR=6.262, P<0.05) and Weight loss during hospitalization (OR=4.363, P<0.05) were risk factors for the physical function of HNC patients 1 month after surgery. For social function 1 month after surgery, weight loss during hospitalization (OR=3.306, P<0.05) was the risk factor.@*Conclusions@#Weight loss during hospitalization in HNC patients with surgical treatment can predict the impairment of function 1 month after surgery. Healthcare providers should pay more attention to perioperative nutritional problems of HNC patients, especially the elder patients, and take effective interventions to control the weight during hospitalization to improve patients′ function and quality of life.

ABSTRACT
OBJECTIVE To investigate the correlative between anxiety and coping mode of parents of children with air way foreign bodies. METHODS Self-rating anxiety scale (SAS) and simplified coping style questionnaire (SCSQ) were used to investigate the anxiety level and coping mode among 212 parents of children with airway foreign bodies. RESULTS The SAS scores of parents of children with airway foreign bodies was considerably higher than China normal, there was significant difference between the two (P 0.05). CONCLUSION The parents of children with airway foreign bodies have higher anxiety level than the norm, they often take an positive coping style.
