ABSTRACT
Objective:To assess the effect of flash glucose monitoring (FGM) compared with self-monitoring of blood glucose (SMBG) on glycemic control, residual islet function, and patient-reported outcomes in children and adolescents with newly diagnosed type 1 diabetes within 1 year.Methods:133 children and adolescents with newly diagnosed T1DM in the T1D clinic of the Second Xiangya Hospital of Central South University from January 2016 to January 2020 were divided into two groups: FGM group ( n=82) and SMBG group ( n=51). The observation indexes included hemoglobin A1c (HbA 1c), fasting and postprandial blood glucose (FBG and 2 h BG), C-peptide (FCP and 2 h CP) during the one-year follow-up, Δ CP (2 h CP-FCP), patient-reported hypoglycemia and questionnaires regarding self-management of diabetes and quality of life. Results:At 6 months, HbA 1c in 2 groups was significantly decreased (all P<0.05); at 6 to 12 months, HbA 1c in FGM group tended to be stable ( P>0.05); at 12 months, HbA 1c in SMBG group was significantly increased compared with 6 months ( P=0.001). At 12 months, HbA 1c in SMBG group was higher than that in FGM group ( P=0.001). At 12 months, FBG in FGM group was equivalent to the baseline level ( P>0.05), while FBG in SMBG group was significantly higher than the baseline level ( P=0.006). 2 h BG only decreased at the 6th and 12th month in FGM group (all P<0.05). The FCP of SMBG group was significantly decreased at 12 months ( P<0.05), and the 2 h CP, Δ CP in the two groups decreased gradually (all P<0.05). FGM group had more hypoglycemic events at 6 and 12 months (all P<0.05). At 6 months, the score of Self-Management of T1D for Adolescents (SMOD-A) in FGM group was significantly improved ( P=0.001). During the follow-up period, the quality of life score of FGM group was stable ( P>0.05), while the quality of life score of SMBG group had a downward trend ( P=0.052). Conclusions:In newly diagnosed children and adolescents with T1DM, early application of FGM for blood glucose management will help to improve HbA 1c and reduce postprandial blood glucose. In addition, the self-management ability of children with FGM was improved after 6 months.
ABSTRACT
Objective:To investigate the characteristics and the risk factors of coronavirus disease 2019 (COVID-19) associated acute kidney injury (AKI).Methods:A retrospective cohort study was performed to examine the basic data, clinical characteristics and prognosis of patients with COVID-19 in Zhongnan Hospital of Wuhan University and Wuhan Fourth Hospital from January 1st to February 1st in 2020. According to the diagnostic criteria of Kidney Disease: Improving Global Outcomes (KDIGO), patients with AKI were included in AKI group and those without AKI were included in non-AKI group. The differences of each index between the two groups were compared. The prognostic value of AKI for COVID-19 was analyzed by Kaplan-Meier survival curve and Cox regression.Results:A total of 394 COVID-19 patients were included, with a total mortality of 5.6%; 37 (9.4%) of them developed AKI. The mortality of patients with COVID-19 associated AKI was 18.9%. There were significant differences in age, gender, smoking history, hypertension history, malignancy history, cardiovascular disease history and cerebrovascular disease history between the two groups. In addition to the difference of serum creatinine (SCr) and blood urea nitrogen (BUN), white blood cell count (WBC), neutrophil count (NEU), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), D-dimer, procalcitonin (PCT) and C-reaction protein (CRP) in AKI group were significantly higher than those in non-AKI group [WBC (×10 9/L): 5.75 (4.13, 7.83) vs. 4.52 (3.35, 5.90), NEU (×10 9/L): 4.55 (2.81, 6.11) vs. 3.06 (2.03, 4.50), AST (U/L): 40.0 (24.5, 69.5) vs. 30.0 (23.0, 42.5), LDH (μmol·s -1·L -1): 5.21 (3.68, 7.57) vs. 4.24 (3.05, 5.53), D-dimer (μg/L): 456 (266, 2 172) vs. 290 (152, 610), PCT (μg/L): 0.33 (0.03, 1.52) vs. 0.01 (0.01, 0.11), CRP (mg/L): 53.80 (26.00, 100.90) vs. 23.60 (9.25, 51.10), all P < 0.05], while lymphocyte count (LYM) and platelet count (PLT) were decreased [LYM (×10 9/L): 0.68 (0.47, 1.05) vs. 0.91 (0.63, 1.25), PLT (×10 9/L): 142.0 (118.0, 190.0) vs. 171.0 (130.0, 2 190.0), both P < 0.05]. The mortality of AKI group was significantly higher than that of non-AKI group [18.9% (7/37) vs. 4.2% (15/357), P < 0.01]. Kaplan-Meier survival curve showed that the 30-day cumulative survival of AKI group was lower than that of non-AKI group (log-rank: P = 0.003). Cox analysis also showed that AKI increased the odds of patients with COVID-19 mortality by 3.2-fold [hazard ratio ( HR) = 3.208, 95% confidence interval (95% CI) was 1.076-9.566, P = 0.037]. Conclusions:The risk of AKI is higher in patients with COVID-19. Early intervention to prevent AKI in patients with COVID-19 is of great significance to improve the prognosis of patients.

ABSTRACT
Objective To investigate the prevalence and the related factors of allergic rhinitis in Xinjiang College students.Methods Five universities'students in Urumqi were chosen as the research subjects,the question-naire survey was conducted by the method of cluster sampling,and the results were analyzed.Results 1 609 ques-tionnaires were valid from 2 000 questionnaires.The prevalence rate of allergic rhinitis was 36.8% in the five univer-sities in Urumqi.Prevalence rate increased with grade.The prevalence rates of drinking,regular cleaning nasal cavity, scrubbing their nose in allergic rhinitis were 43.2%,40.7%,53.8% respectively,which were higher than those in not drinking,not regular cleaning nasal cavity,not scrub nose,the differences were statistically significant (χ2 =6.945,9.679,100.845,all P 0.05).Conclusion Allergic rhinitis not only closely related to the grades and the environmental factors,but also has some connections with living habits(drink,clean nasal cavity and scrub noses).
ABSTRACT
Objective To investigate the expressions of PTEN and p21 genes in Hazak patients with esophageal can-cer. Methods The expressions of PTEN and p21 genes were detected by RT-PCR in 48 samples (cancer tissues and nor-mal tissues) of patients with esophageal cancer. The relationship between the expressions of PTEN and p21 genes, tumor dif-ferentiation, TNM stage, clinical phase and lymph node metastasis were analyzed. Results The positive rates of PTEN gene were 75%and 45.8%in cancer and distant normal tissues. The expression of PTEN was significantly higher in cancer tis-sues than that of distant normal tissues (χ2=8.537,P＜0.05). The positive rates of p21 gene were 95.8%and 97.9%in cancer and distant normal tissues, and no significant difference between them (χ2=0.344,P>0.05). There was no correlation be-tween expressions of PTEN and p21and the tumor differentiation, the depth of invasion and lymph node metastasis in esopha-geal cancer. Conclusion PTEN and p21 genes are not the primary genes for the carcinogenesis of esophageal cancer in Hazak.
ABSTRACT
Objective To evaluate the effect of family interventions on the prevention of falls in elderly hypertensive patients. Methods One hundred elderly hypertensive patients were divided into the experiment group and the control group in equal number. The control group returned for regular visits after discharge while the experiment group received the family intervention including cognitive,psychological,behavioral and environmental intervention.The two groups were compared in terms of fall rate and degree of injury.Results The incidence of falls in the experiment group was significantly lower than that of the control group,the incidence of soft tissue injury after a fall in the experiment group was significantly lower than that of the control group(both P<0.05).Conclusion Family intervention is effective in prevention of falls in elderly hypertensive patients for it may reduce the incidence of falls and the degree of fall injuries.
