With the development of genetics and advances in genetic testing technology,the demand for cancer genetic counseling has increased dramatically.Advanced practice nurses play a key role in personalized health care delivery.The oncology genetic nurse-led genetic counseling services in foreign countries are becoming more and more mature,but in China,the work of oncology genetic counseling started late,and the combination of genetics/genomics with nursing is still in its infancy.There is still a lack of relevant research on oncology genetic nurses.This article introduced the qualification certification,core competence and clinical practice content of foreign oncology genetic nurses,and summarized the clinical practice effect of oncology genetic nurses and the enlightenment to China's advanced nursing practice,which provided references for the construction of oncology genetic nurses training programs and clinical service models suitable for China's national conditions,so as to meet the needs of the development of advanced nursing practice and the growing demand for precision oncology and high-quality genetic medical care.

The twenty-first century has already recorded more than ten major epidemics or pandemics of viral disease, including the devastating COVID-19. Novel effective antivirals with broad-spectrum coverage are urgently needed. Herein, we reported a novel broad-spectrum antiviral compound PAC5. Oral administration of PAC5 eliminated HBV cccDNA and reduced the large antigen load in distinct mouse models of HBV infection. Strikingly, oral administration of PAC5 in a hamster model of SARS-CoV-2 omicron (BA.1) infection significantly decreases viral loads and attenuates lung inflammation. Mechanistically, PAC5 binds to a pocket near Asp49 in the RNA recognition motif of hnRNPA2B1. PAC5-bound hnRNPA2B1 is extensively activated and translocated to the cytoplasm where it initiates the TBK1-IRF3 pathway, leading to the production of type I IFNs with antiviral activity. Our results indicate that PAC5 is a novel small-molecule agonist of hnRNPA2B1, which may have a role in dealing with emerging infectious diseases now and in the future.

Platelets are reprogrammed by cancer via a process called education, which favors cancer development. The transcriptional profile of tumor-educated platelets (TEPs) is skewed and therefore practicable for cancer detection. This intercontinental, hospital-based, diagnostic study included 761 treatment-naïve inpatients with histologically confirmed adnexal masses and 167 healthy controls from nine medical centers (China, n = 3; Netherlands, n = 5; Poland, n = 1) between September 2016 and May 2019. The main outcomes were the performance of TEPs and their combination with CA125 in two Chinese (VC1 and VC2) and the European (VC3) validation cohorts collectively and independently. Exploratory outcome was the value of TEPs in public pan-cancer platelet transcriptome datasets. The AUCs for TEPs in the combined validation cohort, VC1, VC2, and VC3 were 0.918 (95% CI 0.889-0.948), 0.923 (0.855-0.990), 0.918 (0.872-0.963), and 0.887 (0.813-0.960), respectively. Combination of TEPs and CA125 demonstrated an AUC of 0.922 (0.889-0.955) in the combined validation cohort; 0.955 (0.912-0.997) in VC1; 0.939 (0.901-0.977) in VC2; 0.917 (0.824-1.000) in VC3. For subgroup analysis, TEPs exhibited an AUC of 0.858, 0.859, and 0.920 to detect early-stage, borderline, non-epithelial diseases and 0.899 to discriminate ovarian cancer from endometriosis. TEPs had robustness, compatibility, and universality for preoperative diagnosis of ovarian cancer since it withstood validations in populations of different ethnicities, heterogeneous histological subtypes, and early-stage ovarian cancer. However, these observations warrant prospective validations in a larger population before clinical utilities.

A young female patient presented with fever, arthralgia, and rash was diagnosed with adults still's disease. When treated with glucocorticoid steroid, the above patient progressed to anuria, sudden, and confusion. After a teamwork involving different departments, the patient was finally diagnosed with atypical hemolytic uremic syndrome (aHUS) and treated with good outcome. aHUS is a rare disease, while Eculizumab is an orphan drug. The diagnosis and treatment of the patient reveals the importance of multidisciplinary team on the diagnosis and treatment of rare and difficult diseases.

Astrocytes are a heterogenous group of macroglia present in all regions of the brain and play critical roles in many aspects of brain development, function and disease. Previous studies suggest that the B-cell lymphoma-2 associated X protein (BAX)-dependent apoptosis plays essential roles in regulating neuronal number and achieving optimal excitation/inhibition ratio. The aim of the present paper was to study whether BAX regulates astrocyte distribution in a region-specific manner. Immunofluorescence staining of SOX9 was used to analyze and compare astrocyte density in primary somatosensory cortex, motor cortex, retrosplenial cortex and hippocampus in heterozygous and homozygous BAX knockout mice at age of six weeks when cortical development has finished and glia development has reached a relatively steady state. The results showed that astrocyte density varied significantly among different cortical subdivisions and between cortex and hippocampus. In contrast to the significant increase in GABAergic interneurons, the overall and region-specific astrocyte density remained unchanged in the cortex when BAX was absent. Interestingly, a significant reduction of astrocyte density was observed in the hippocampus of BAX knockout mice. These data suggest that BAX differentially regulates neurons and astrocytes in cortex as well as astrocytes in different brain regions during development. This study provided important information about the regional heterogeneity of astrocyte distribution and the potential contribution of BAX gene during development.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

Objective:To summarize the best evidence for prevention and management of aspiration in neurosurgical ICU patients and provide evidence for clinical nursing work.Methods:Relevant evidence on prevention and management of aspiration in neurosurgical ICU patients, including guidelines, consensus, system reviews, and randomized controlled trials (RCTs) which were published from 1st January, 2010 to 30th June, 2019 in any language was retrieved from guideline websites, relevant websites and databases. Two researchers evaluated the quality of the included literature and performed evidence extraction on those literatures that met the quality standards.Results:Totally 9 clinical practice guidelines, 8 expert consensus, 13 Meta analysis / systematic reviews and 10 RCTs were included, which were collected and extracted to form the final version of best evidence for aspiration prevention and management including 10 primary indicators and 29 secondary indicators.Conclusions:Medical staff should take effective measures in early assessment of aspiration risks, artificial airway management, position management, enteral nutrition management, sedation and analgesia management, etc., and reduce the incidence of aspiration in neurosurgical ICU patients by applying the best evidence. In addition, hospitals should provide various forms of education and training to medical staff, form transdisciplinary cooperation teams, and strengthen the prevention and management of aspiration.

OBJECTIVE: To study the effect of hyperoxic exposure on the dynamic expression of heme oxygenase-1 (HO-1) and glutamate-L-cysteine ligase catalytic subunit (GCLC) in the lung tissue of preterm neonatal rats. METHODS: Cesarean section was performed for rats on day 21 of gestation to obtain 80 preterm rats, which were randomly divided into air group and hyperoxia group after one day of feeding. The rats in the air group were housed in room air under atmospheric pressure, and those in the hyperoxia group were placed in an atmospheric oxygen tank (oxygen concentration 85%-95%) in the same room. Eight rats each were selected from each group on days 1, 4, 7, 10, and 14, and lung tissue samples were collected. Hematoxylin and eosin staining was used to observe the pathological changes of lung tissue at different time points after air or hyperoxic exposure. Western blot and RT-qPCR were used to measure the protein and mRNA expression of HO-1 and GCLC in the lung tissue of preterm rats at different time points after air or hyperoxic exposure. RESULTS: Compared with the air group, the hyperoxia group had a significant reduction in the body weight (P<0.05). Compared with the air group, the hyperoxia group had structural disorder, widening of alveolar septa, a reduction in the number of alveoli, and simplification of the alveoli on the pathological section of lung tissue. Compared with the air group, the hyperoxia group had significantly lower relative mRNA expression of HO-1 in the lung tissue on day 7 and significantly higher expression on days 10 and 14 (P<0.05). Compared with the air group, the hyperoxia group had significantly lower mRNA expression of GCLC in the lung tissue on days 1, 4, and 7 and significantly higher expression on day 10 (P<0.05). Compared with the air group, the hyperoxia group had significantly higher protein expression of HO-1 in the lung tissue on all days, and the protein expression of GCLC had same results as HO-1, except on day 1 (P<0.05). CONCLUSIONS Hyperoxia exposure may lead to growth retardation and lung developmental retardation in preterm rats. Changes in the protein and mRNA expression of HO-1 and GCLC in the lung tissue of preterm rats may be associated with the pathogenesis of hyperoxia-induced lung injury in preterm rats.

AIM To investigate the efficacy and safety of Chinese Jing Liqueur (Curculiginis Rhizoma,Angelicae sinensis Radix,Cistanches Herba,etc.) in relieving main symptoms of patients with Kidney Yang Deficiency Syndrome.METHODS Within eight-week trial,one hundred and twenty patients randomly and equally assigned to control group and experimental group took 50 mL Chinese Jing Liqueur and 50 mL 10％ diluted Chinese Jing Liqueur,respectively.The grading scale for Kidney Yang Deficiency Syndrome and change curve for body surface temperature after drinking were established on day 0,the 4th week day and the 8th week day.The blood samples were collected for blood hemorheologies detection as well.An array of measurements before and after drinking,the Kidney Yang Deficiency Syndrome scores,single symptom scores,body surface temperature and hemorheologies between the two groups were thus compared.RESULTS The experimental group displayed a significantly higher clinical cure rate (31.034％) than the control group (5.172％) (P =0.000),total effective rate (69.966％)than the control group (34.483％) (P =0.000).The experimental group didn't compromise its superiority to the control group if evaluated by improvement in chilly sensation and the cold limbs (35.593％ to 6.667％,P =0.000);and by the fibrinogen level [(2.845 ± 0.724) g/L to (2.500 ± 0.395) g/L,P =0.004)].No significant difference in incidence of adverse reactions between the two groups was observed (P =0.619).Meanwhile,Chinese Jing Liqueur's power in improving the patients' fatigue and weakness of waist and knees,hyposexuality,listlessness,nocturia and lower extremity edema was noticed as well.CONCLUSION For patients with Kidney Yang Deficiency Syndrome,Chinese Jing Liqueur proves its efficacy in improving their main symptoms through enhancing the basic skin temperature and prolonging the duration of skin temperature rise.

A comprehensive analytical method based on UFLC-QTRAP-MS-MS was developed for the simultaneous determination of 15 kinds of amino acids and 12 kinds of nucleosides of three species in Termitomyces. The separation was carried out on a Waters XBridge Amide column (2.1 mm×100 mm,3.5 μm) with gradient elution of mobile phase of 0.2% formic acid in water-0.2% formic acid in acetonitrile at a flow rate of 0.6 mL•min⁻¹, and column temperature was maintained at 30 ℃. The target compounds were analyzed by the positive ion multiple reaction monitoring (MRM) mode. The principal component analysis(PCA) was made to standardized treatment for the comprehensive evaluation of different species in Termitomyces. The 15 kinds of amino acids and 12 kinds of nucleosides multiple constituents showed good linearity (r>0.997 3) in the range of the tested concentration.The average recoveries ranged from 95.14% to 105.0%,and the relative standard deviations were less than 5.0%. The comprehensive evaluation index obtained with PCA showed that the Termitomyces albuminosus was significantly higher than others in amino acids and in nucleosides, of which the T. aurantiacus was the best. The developed method with good repeatability and accuracy was suitable for the simultaneous determination of multiple functional substances,which provided a new basis for the comprehensive assessment and overall control of the quality of Termitomyces fungi.
