SARS-CoV-2 infection causes complicated clinical manifestations with variable multi-organ injuries, however, the underlying mechanism, in particular immune responses in different organs, remains elusive. In this study, comprehensive transcriptomic alterations of 14 tissues from rhesus macaque infected with SARS-CoV-2 were analyzed. Compared to normal controls, SARS-CoV-2 infection resulted in dysregulation of genes involving diverse functions in various examined tissues/organs, with drastic transcriptomic changes in cerebral cortex and right ventricle. Intriguingly, cerebral cortex exhibited a hyperinflammatory state evidenced by significant upregulation of inflammation response-related genes. Meanwhile, expressions of coagulation, angiogenesis and fibrosis factors were also up-regulated in cerebral cortex. Based on our findings, neuropilin 1 (NRP1), a receptor of SARS-CoV-2, was significantly elevated in cerebral cortex post infection, accompanied by active immune response releasing inflammatory factors and signal transmission among tissues, which enhanced infection of the central nervous system (CNS) in a positive feedback way, leading to viral encephalitis. Overall, our study depicts a multi-tissue/organ transcriptomic landscapes of rhesus macaque with early infection of SARS-CoV-2, and provides important insights into the mechanistic basis for COVID-19-associated clinical complications.

Objective: To analyze the clinical characteristics of children with Burkitt lymphoma (BL) and to summarize the mid-term efficacy of China Net Childhood Lymphoma-mature B-cell lymphoma 2017 (CNCL-B-NHL-2017) regimen. Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ²=4.16, P=0.041) and group C2 (χ²=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ²=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.

OBJECTIVE: To assess changes of nutritional status by comprehensive nutrition assessment including nutritional risk screening, dietary assessment, blood biochemical index, and body composition in acute leukemia patients who had undergone chemotherapy. METHODS: A total of 169 patients with acute leukemia treated at The First Affiliated Hospital of Soochow University from June 2018 to August 2019 were recruited for this study. Before and after chemotherapy, the NRS-2002 and PG-SGA scales, dietary intake, blood biochemical index and body composition were evaluated to compare the changes of nutritional status. RESULTS: NRS-2002 score and PG-SGA score after chemotherapy were significantly increased than those before chemotherapy (P<0.001). Many patients had insufficient nutritional intake during chemotherapy, and the dietary intake score of patients with induction chemotherapy was significantly lower than that of patients with consolidation chemotherapy (P=0.043). The results of multivariate analysis showed that induction chemotherapy was the independent risk factor for the increase of PG-SGA scores and the decrease of dietary intake (all P<0.05). After chemotherapy, the white blood cell count, hemoglobin, and platelet count were significantly decreased (P<0.001), the prealbumin was significantly increased (P<0.001), and the blood glucose was increased (P=0.04), but albumin was not significantly changed. The weight, body mass index, fat-free mass, skeletal muscle mass and intracellular water were all significantly decreased (P<0.001), and visceral fat area was increased significantly after chemotherapy (P<0.05), especially in newly-diagnosed acute lymphoblastic leukemia patients after the induction of chemotherapy. CONCLUSION The nutritional status of patients with acute leukemia has undergone significant changes after chemotherapy. A single indicator has limited significance for nutritional status assessment. Comprehensive assessment of nutritional status by multiple tools is worthy of clinical application.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

OBJECTIVE: To observe the effect of moxibustion on proteins related with apoptosis of hippocampal neurons in rats with vascular dementia (VD), and to explore the possible mechanism of moxibustion on improving VD. METHODS: Thirty SD rats were selected from 100 rats (3 rats were excluded) and randomly divided into a normal group and a sham operation group, 15 rats in each group. The remaining 67 rats were treated with ischemia-reperfusion method at bilateral common carotid artery to establish VD model. The 45 rats with successful VD model were randomly divided into a model group, a moxibustion group and a medication group, 15 rats in each group. On the 7th day after successful modeling, the rats in the moxibustion group were treated with suspended moxibustion at "Guanyuan" (CV 4), "Mingmen" (GV 4) and "Dazhui" (GV 14), 15 min per acupoint, once a day; there was 1 d of rest after 6 d of moxibustion, and the treatment was given for 4 weeks. The rats in the medication group was treated with nimodipine tablets by gavage, 2 mg/kg per day, 3 times a day for 4 weeks. Before and after intervention, the Morris water maze test was used to detect the escape latency of rats in each group; after the intervention, the TUNEL method was used to detect the apoptosis rate of neurons in hippocampal CA1 area; the immunofluorescence double labeling method was used to detect the number of co-expression positive cells of B-cell lymphoma-2 (Bcl-2)/neuronal nuclear antigen (NeuN) and Bcl-2-associated X protein (Bax)/NeuN in hippocampal CA1 area; the immunofluorescence single labeling method was used to detect cytochrome C (cytC) and outer mitochondrial membrane receptor Tom20 (Tom20) in hippocampal CA1 area; the Western blot method was used to detect the p53 upregulated modulator of apoptosis (PUMA) in hippocampus. RESULTS: Before intervention, compared with the normal group and the sham operation group, the escape latency in the model group, the moxibustion group and the medication group was prolonged ( CONCLUSION Moxibustion could improve the cognitive function of VD rats, which may be related to reducing the expression of Bax, cytC, Tom20 and PUMA protein in hippocampal CA1 area, promoting the release of Bcl-2 and inhibiting the apoptosis of hippocampal neurons.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Objective:To explore the characteristics of vowel production of dysarthria after stroke, and the relationship between vowel production and speech clarity. Methods:From October, 2019 to January, 2020, 19 patients with post-stroke dysarthria and 18 healthy controls were asked to read a short essay to extract vowels, and measured the jaw distance, tongue distance, F2i/F2u, vowel space area (VSA), vowel articulation index (VAI), F1 and F2 variability, and speech clarity. The correlation between vowel production and speech clarity were analyzed. Results:Tongue distance, F2i/F2u, VSA, VAI, and speech clarity were less in the patients than in the controls (|t| > 2.268, P < 0.05), while F2 variability was more (t = 2.375, P < 0.05). F2i/F2u (r = 0.465), VAI (r = 0.488) and F2 variability (r = -0.504) were correlated to speech clarity (P < 0.05). Conclusion:The vowel production impaired in patients with post-stroke dysarthria, featured as abnormal articulatory movements, concentration of vowels and poor stability of vowels, which impacts the speech clarity.

Methods:The diagnosis of disease and functioning was discussed with ICD-11 and ICF. The assessment tools were analyzed with ICF. A holistic rehabilitation solution was constructed with ICF and ICHI.

Objective To understand the epidemiological features and changing patterns of intestinal parasitic diseases in Jiangxi Province from 1989 to 2014, so as to provide scientific evidence for formulating the preventive and control strategy for intestinal parasitic diseases. Methods The data regarding the status of intestinal parasitic diseases in Jiangxi Province were captured from the 1989 national survey on the distribution of human parasites in China and the 2014 national survey on major human parasitic diseases in China, and the status of human intestinal parasite infections was compared between the two surveys in Jiangxi Province. Results The prevalence rate of human intestinal parasite infections was 79.59% and 9.64% in Jiangxi Province in 1989 and 2014, with a decline rate of 87.89% during the 25-year period (χ² = 30 870.5, P < 0.01). There were 24 and 20 species of human intestinal parasites detected in Jiangxi Province in 1989 and 2014, respectively, with totally 26 species detected during the two surveys. In Jiangxi Province, the 3 most highly prevalent human intestinal parasites included Ascaris lumbricoides (71.06%), hookworm (17.61%) and Enterobius vermicularis (17.59%) in 1989, and E. vermicularis (13.73%), hookworm (4.66%), whipworm (0.95%) in 2014. A higher rate of human intestinal parasite infections was found in females than in males in both surveys in Jiangxi Province (P < 0.01), and the prevalence of human intestinal parasite infections reduced by 82.50% to 95.31% in different age groups in Jiangsu Province during the 25-year period. Conclusions The prevalence of human intestinal parasite infections shows a remarkable decline tendency in Jiangxi Province, and soil-transmitted nematodes remain the main species of human intestinal parasites in Jiangxi Province.

OBJECTIVE: To explore the curative effect of progressively integrated sandplay therapy on core symptoms and sleep management in preschool children with mild-to-moderate autism spectrum disorder (ASD). METHODS: A total of 50 mild-to-moderate ASD preschool children were randomly divided into an experimental group (n=25) and a control group (n=25). The control group was treated with structured teaching and auditory integration training (AIT). Based on these, the experimental group was treated with progressively integrated sandplay therapy. The Autism Behavior Checklist (ABC), Children Autism Rating Scale (CARS), Social Responsiveness Scale (SRS), Children's Sleep Habit Questionnaire (CSHQ) and emotion recognition tools were used to evaluate the overall curative effect before treatment and 3 months after treatment. RESULTS: The experimental group had significantly lower scores of feeling, social interaction, somatic motor, language factor, total ABC and total CARS than the control group (P<0.05). The experimental group had also significantly lower scores of social cognition, social communication, social motivation, autistic behavior factor and total SRS than the control group (P<0.05). The experimental group had a significantly higher accurate rate of recognition of the upper facial expression and lower facial expression than the control group (P<0.05). The experimental group had significantly lower scores of bedtime resistance, sleep onset, sleep duration, night waking, daytime sleepiness, and total CSHQ than the control group (P<0.05). The experimental group had significantly reduced themes of wounding and significantly increased themes of healing after sandplay therapy (P<0.05). CONCLUSIONS Progressively integrated sandplay therapy can effectively improve the core symptoms and sleep quality of preschool children with mild-to-moderate ASD, which can be used as an early rehabilitation measure.
