Objective:To explore the effect of nirmatrelvir/ritonavir (Paxlovid) on renal function in patients with coronavirus disease 2019 (COVID-19) and renal insufficiency.Methods:Clinical data of renal insufficiency patients with COVID-19, who were hospitalized at Beijing Ditan Hospital, Capital Medical University from March 23, 2022 to April 30, 2023 and received Paxlovid treatment, were collected. A retrospective analysis was conducted on the incidence of Paxlovid-related acute kidney injury (AKI) and changes of blood urea, serum creatinine (Scr), blood uric acid, and estimated glomerular filtration rate (eGFR) in patients before and after Paxlovid treatment.Results:A total of 386 patients were included in the analysis, including 220 males (57.0%) and 166 females (43.0%), with a median age of 79 years. COVID-19 was classified as asymptomatic in 42 patients (10.9%), mild in 175 patients (45.4%), moderate in 126 patients (32.6%), severe in 34 patients (8.8%), and critical in 9 patients (2.3%). The renal insufficiency was mild in 246 patients (63.7%), moderate in 110 patients (28.5%), and severe in 30 patients (7.8%). Among 386 patients, 16 (4.1%) developed AKI during Paxlovid treatment or within 48 hours after withdrawal, 5 (1.3%) of which were judged to be related to Paxlovid. The 5 patients aged 70 years and above, and all used nephrotoxic drugs. After Paxlovid treatment, the blood urea, Scr, blood uric acid, and eGFR in the 386 patients were all improved compared to before, and the differences were statistically significant [Scr: (133.8±9.3) μmol/L vs. (111.7±6.6) μmol/L; blood uric acid: (335.9±7.1) μmol/L vs. (291.9±5.8) μmol/L; eGFR: (63.4±1.1) ml/(min·1.73 m 2) vs. (69.1±1.2) ml/(min·1.73 m 2); all P<0.05]. Conclusions:The overall safety of Paxlovid treatment for COVID-19 in patients with renal insufficiency is good, and it has no significant impact on the renal function in the vast majority of patients. However, for elderly people aged 70 years and above, especially for those who have combination medications of nephrotoxic drugs, the occurrence of AKI should still be vigilant.

Objective: To explore the predictive values of routine blood test results for iron deficiency (ID) screening in children. Methods: Routine blood test results and serum ferritin (SF) levels from 1 443 healthy children (862 boys, 581 girls) aged 6 months to 18 years, who were seen for well-child visits between June 2017 and May 2019 in Children′s Hospital, Zhejiang University School of Medicine, were retrospectively analyzed. ID was defined as SF<20 μg/L, iron deficiency anemia (IDA) as ID with anemia (hemoglobin(Hb)<110 g/L at 6 months-5 years of age, Hb<120 g/L at 6-18 years of age), non-anemia ID as ID without anemia, non-ID anemia as SF≥20 μg/L with anemia, and healthy control subjects as those with SF≥20 μg/L but without anemia. The blood test results including Hb, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), red blood cell distribution width (RDW), and the percentage of low hemoglobin density (LHD) of healthy control, non-anemia ID, non-ID anemia, and IDA groups were compared by analysis of variance (ANOVA) or non-parametric test, quantitative data were described as ±s or M(interquartile range), and receiver operating characteristic curve (ROC) analysis was applied to assess predictive values of routine blood test results and LHD for detecting IDA and ID. Results: Among 1 443 children with median age of 2.1(3.3) years, 1 061 children were in healthy control group, 292 in non-anemia ID group, 43 in non-ID anemia group and 47 in IDA group. The prevalence of ID was much higher than that of anemia (23.5% (339/1 443) vs. 6.2% (90/1 443) , χ²=169.76, P<0.01). Compared with control group, non-anemia ID group showed higher LHD (0.088 (0.093) vs.0.073 (0.068), P<0.01) and RDW (0.131±0.013 vs. 0.126±0.008, P<0.01), lower MCV ((80±4) vs. (83±4) fl, P<0.01) and MCHC values ((326±9) vs. (329±8) g/L, P<0.01). IDA group showed higher LHD (0.322(0.544)) and RDW (0.151±0.018), lower MCV ((73±6) fl) and MCHC values((309±14) g/L) than non-anemia ID group (all P<0.01). The area under curve (AUC) values of MCHC, LHD, RDW and MCV for detecting ID were 0.63 (95%CI: 0.60-0.67), 0.63 (95%CI:0.60-0.67), 0.67 (95%CI: 0.63-0.70) and 0.73 (95%CI: 0.69-0.76) respectively. With cutoff limits (MCV<80.2 fl, RDW>0.131 or MCHC<322 g/L), MCV, RDW and MCHC showed higher sensitivity for screening ID than hemoglobin (0.540, 0.469 and 0.336 vs. 0.139, χ²=121.70, 87.47, 35.56, all P<0.01). Conclusion MCV, RDW and MCHC can be used to screen ID in primary health care settings.

Objectives: The purpose of this study is to understand the relationships among plasma glucose, blood pressure level and Traditional Chinese Medicine (TCM) syndromes in Shanghai community residents, and provide a theoretical basis for the prevention of community chronic disease based on TCM syndrome differentiation.Methods: Residents above35 years old will attend the Type 2 Diabetes Mellitus (T2 DM) risk assessment at Community Health Center. By distributing questionnaires and performing glucose testing, we screened the residents at high risk of T2 DM, and conducted a physical examination of them. Further, a body constitution questionnaire was required to be completed by the residents. Results: In total, 933 residents were screened. The plasma glucose and blood pressure levels related to age, waist circumference, hip circumference, body mass index (BMI) and waist-to-height ratio (WHtR) . Residents with increasing blood pressure have an increased risk of T2 DM (P ＜ 0.01) . Total 529 questionnaires were completed, and 129 subjects (24.4％) have single TCM syndromes, 75 subjects (14.2％) have at least two TCM syndromes and 325 subjects (61.4％) have no TCM syndromes. Conclusion: Plasma glucose and blood pressure are associated and interacted with several physical indexes. TCM syndromes distribution was found no significant change among subjects with different plasma glucose and blood pressure.

Objective To explore the correlation of anxiety and depression with social support among caregivers of children with mental retardation and major related influencing factors.Methods 64 mothers of children with mental retardation were investigated by using the questionnaires of SAS,SDS and SSRS.The results underwent analysis.Results The incidence of anxiety among mothers of children with mental retardation was 23.4％,the incidence of depression was 40.7％.Mothers had higher scores of SAS and SDS than the national norm.The total score of social support was(32.19±5.02),which was lower than the national norm.The anxiety and depression was negatively correlated with social support.The influencing factors of anxiety and depression of mothers were family income.Conclusions The anxiety and depression among mothers of children with mental retardation was evident,the social supports for those mothers were insufficient.Effective social support was propitious to abate the anxiety and depression and promote quality of life of those children with mental retardation and their mothers.

Objective To provide a reasonable clinical evidence and testing index for acute myocardial infarction (AMI) early diagnosis by investigating the levels of serum ischemia-modified album(IMA),cardiac troponin I(cTnI) and high-sensitivity C-reactive protein (hs-CRP) in patients with AMI.Methods 66 cases with AMI were divided into two groups by the time of starting attack chest pain to clinic,the time of 0-4h as E group (39 cases),4-8h as F group (27 cases),another 59 healthy persons in the control group were detected.Then collected serum samples from each case to detect the concentration of the IMA,cTnI and hs-CRP.Results The levels of serum IMA,cTnI and hs-CRP in E group were significantly higher than those in the control group( P ＜ 0.05 or P ＜ 0.001 ),in addition to the IMA level was higher than normal,cTnI and hs-CRP levels were in the normal range.The levels of serum IMA,cTnI and hs-CRP in F group were significantly higher than the levels of control group( P ＜0.05 ) and also above the normal.Conclusion IMA,cTnI and hs-CRP not only can be used as the effective index for AMI early diagnosis,but also help for early diagnosis.The results provide a reliable basis for disease treatment and condition development.

Objective To investigate the correlation of father involvement with early social adaptation behaviors.Methods With social adaptation scale for infant-junior middle school' s student and a self-made questionnaire,1246 normal children,age from 16 to 72 months,were investigated.Regression analysis was performed to get the correlation of social adaptation with time and activities of father involved.Results After controlling for mother-,child- and family-related factors,the regression analysis showed that standard score of social adaptation was positively rehted with the time of father involved ( β =0.05,P=0.03 ),the time father invloved explain 12％of the variation of social adaptation.The father-child activities were related with social adaptation behavior,playing was related with work skills (β =0.09,P＜0.01 ) and socialization ( β =0.06,P＜0.05),story listening related with communication ( β =0.07,P ＜ 0.05) and self-management ( β =0.06,P ＜ 0.05 ),other activities related with self-dependence ( β =0.07,P＜0.05) and work skills ( β =0.06,P＜0.05).Conclusion The time and activities of father involved are related with children' s social adaptation.The effect of father involvement on early social adaptation is positive.
