Metabolic indicators associated with non-communicable diseases deteriorated in COVID-19 outbreak: evidence from a two-center, retrospective study

ObjectiveOur study aimed to investigate whether the metabolic indicators associated with non-communicable diseases (NCDs) in the general population have changed during the COVID-19 outbreak. METHODSThis retrospective self-controlled study enrolled adult participants with metabolic indicators relate to NCDs followed at Fujian Provincial Hospital and Fujian Provincial Hospital South Branch. The metabolic indicators followed during January 1, 2020 and April 30, 2020, the peak period of the COVID-19 epidemic in China, were compared with the baseline value in the same period last year. Pared-samples T-test and Wilcoxon signed-rank test were performed to analyze the differences between paired data. ResultsThe follow-up total cholesterol was significantly increased than that of the baseline (4.73 (4.05, 5.46) mmol/L vs 4.71 (4.05, 5.43) mmol/L, p=0.019; n=3379). Similar results were observed in triglyceride (1.29 (0.91, 1.88) vs 1.25 (0.87, 1.81) mmol/L, p<0.001; n=3381), uric acid (330.0 (272.0, 397.0) vs 327.0 (271.0, 389.0) umol/L, p<0.001; n=3364), and glycosylated hemoglobin (6.50 (6.10, 7.30) vs 6.50 (6.10, 7.20) %, p=0.013; n=532). No significant difference was observed in low density lipoprotein, body mass index and blood pressure. ConclusionsMetabolic indicators associated with NCDs deteriorated in the COVID-19 outbreak. We should take action to prevent and control NCDs without delay.

Thoughts on Higher Medical Education Under Major Public Health Emergencies: Thinking Ahead After COVID-19 Outbreak

ImportanceThe spread of coronavirus disease 2019 (COVID-19) has posed great threat to peoples health and several medical schools in the world suspended classes as a precaution against the virus. China has also adopted precautionary measures to keep medical schools running without suspending classes. Thinking ahead after COVID-19 Outbreak is important. ObjectiveTo explore the most suitable teaching and learning pattern in medical school during COVID-19 Outbreak. DesignThis study is a case-control study. We had tried to apply a new blended teaching model based on 5G network that combined team-based learning (TBL) and online interaction to the students before the outbreak and then universities responded to the COVID-19 outbreak by closing campuses and shifting to other forms of distance learning. In other word, the courses started using blended teaching model before COVID-19 outbreak and might last using other forms of distance learning throughout the pandemic. Five Point Likert Scale Questionnaires which contains 20 items were used, and the effect of the two kinds of teaching patterns was compared by evaluating the indicators of core competencies of students including professionalism, attitude towards learning, knowledge and learning skills, teamwork skills, motivation in learning, adaptability and acceptance of the courses and network environment. SettingOur study based on a single center. ParticipantsFifty fourth-year medical students receiving the "5+3" pattern courses regarding internal medicine were enrolled in the study. Exposure(s) (for observational studies)The teaching and learning patter started using blended teaching model before COVID-19 outbreak and might last using other forms of distance learning throughout the pandemic. Main Outcome(s)According to the descriptive statistical analysis of the first part of the questionnaire (question 1-16), the average score of adaptability and acceptance of the courses is 2.60 lower than 3, indicating that students are more adapted to other forms of distance learning during COVID-19 outbreak; the average score of the rest of the questions is higher than 3, indicating that blended teaching model based on 5G network is superior to other forms of distance learning. The number of male students who are inclined to the blended teaching model based on 5G network is 0.13 times as much as that of female students (95%CI:0.028[~]0.602, p=0.009). ResultsOnline forms of distance learning were accepted by the students. Female students had higher expectations on the course and were more likely to adapt well to the change during the COVID-19 outbreak. However, all students preferred the blended teaching model based on 5G network that combined team-based learning (TBL) and online interaction before the pandemic. ConclusionIt indicates that medical education based on 5G network that combined team-based learning (TBL) and online interaction is a more suitable option to teach medical students online. Chinas experience in online higher medical education may serve as a reference to other countries during the pandemic.

Approach to the patient with Klinefelter syndrome combined with neuropsychological abnormality / 中华内分泌代谢杂志

Klinefelter syndrome(KS) is the most common sex chromosome disorder in males,which is caused by the presence of the extra X chromosome that maybe inherited from mother or father. Approximately 80% karyotype of the cases is 47,XXY. KS is characterized by small firm testes, hypergonadotropic hypogonadism, infertility,gynaecomastia, increased height. However, cognitive disabilities and psychiatric disorders are rarely diagnosed in KS because they lack screening in related aspects. At the present, the pathogenesis of cognitive disabilities and increased risk of psychiatric diseases in KS have not been delineated. In this article,we report two cases of KS,and review their clinical manifestations,diagnosis,and treatments.

Association of napping and night-time sleep with impaired glucose regulation, insulin resistance and glycated haemoglobin in Chinese middle-aged adults with no diabetes: a cross-sectional study.

OBJECTIVE: To assess associations between napping and night-time sleep duration with impaired glucose regulation, insulin resistance (IR) and glycated haemoglobin (HbA1c). DESIGN: Cross-sectional study. SETTING: Fujian Province, China, from June 2011 to January 2012. PARTICIPANTS: This study enrolled 9028 participants aged 40-65 years. Data of 7568 participants with no diabetes were included for analysis. Type 2 diabetes was defined applying WHO criteria. OUTCOME MEASURES: Participants' daytime napping and night-time sleep duration data were collected using a standardised self-reported Chinese-language questionnaire about sleep frequency and quality. Anthropometric and laboratory parameters were also measured. IR was defined as a HOMA-IR index value >2.50. ORs and 95% CIs were derived from multivariate logistic regression models. RESULTS: Participants (mean age 51.1±7.0 years) included 3060 males and 4508 females with average night-time sleep of 7.9 h. A higher proportion of males napped than females. After adjustment for potential confounders, ORs for HbA1c >6.0% were 1.28 and 1.26 for those napping ≤1 h and >1 h (p=0.002 and p=0.018), respectively. Statistically significant differences in IR between nappers and non-nappers were only marginal clinically. Odds for HbA1c >6.0% were significantly lower in participants with longer night-time sleep durations than in the reference group (>8 h vs 6-8 h). Odds for IR were significantly lower in participants whose night-time sleep hours deviated from the reference group (<6 h, >8 h vs 6-8 h) CONCLUSIONS: Chinese middle-aged adults with no diabetes who napped had higher HbA1c and IR; those with shorter night-time sleep durations had increased HbA1c. Night-time sleep hours that are either <6 or >8 tend to be associated with lower odds for IR. Further studies are necessary to determine the underlying clinical significance and mechanisms behind these associations.

AMP-activated protein kinase inhibits KiSS-1 gene expression through SP1 in the hypothalamic GT1-7 neurons / 中华内分泌代谢杂志

The effect of AMP-activated protein kinase (AMPK) on KiSS-1 mRNA levels was detected by realtime PCR in the hypothalamic GT1-7 neurons. The promoter activity of KiSS-1 gene was detected by DualLuciferase Reporter Assay System.The effects of AMPK on the protein expression and subcellular distribution of SP1 were determined by Western blot.The results showed that AMPK reduced the mRNA expression and promoter activity of KiSS-1 gene while SP1 increased the promoter activity of KiSS-1 gene. Besides,AMPK alse decreased the translocation of SP1.These results suggest that AMPK may inhibit the expression of KiSS-1 gene by decreasing the translocation of SP1 from cytoplasm to nucleus in the hypothalamus GT1-7 neurons.
