Objective:To analyze the influence of lifestyle changes on body weight and metabolic parameters during the early stage of corona virus disease 2019 (COVID-19) epidemic and regular epidemic prevention period in physical examination population.Methods:A total of 801 subjects from Nanjing enterprises and institutions who underwent physical examination in the Department of Health Promotion Center, the First Affiliated Hospital of Nanjing Medical University in May of 2019 to 2021 were included in this study. The basic information and data of body mass index, fasting blood glucose, total cholesterol, low density lipoprotein cholesterol (LDL-C), triglyceride and uric acid were collected. Information about dietary and exercise habits was obtained through pre-examination questionnaires. The data of 2019 was set as baseline data, data of 2020 represented information during the early stage of COVID-19 epidemic and data of 2021 represented information in regular epidemic prevention period. The subjects were divided into underweight group, normal weight group, overweight group, and obese group according to the body mass index at baseline. The Friedman test was applied to compare changes in body mass index and metabolic parameters across the population. Chi-square test was used to compare changes in dietary and exercise habits. Multivariate logistic regression analysis was adopted to explore the influencing factors of body mass index changes.Results:During the early stage of COVID-19 epidemic, the proportion of weight gain was the highest in the underweight group (42.9%), the proportion of weight loss was the highest in the overweight group (24.2%), and the obese group has the most stable body weight (70.6%) ( P=0.004). Men ( OR=0.56, 95% CI: 0.36-0.87) were less likely to gain weight than women ( P=0.010). There was no significant differences in weight change among all groups in the regular epidemic prevention period ( P=0.380). During the early stage of COVID-19 epidemic, the levels of fasting blood glucose, total cholesterol and LDL-C were significantly lower than those of baseline [4.98 (4.66, 5.42) vs 5.23 (4.91, 5.66) mmol/L, 4.98 (4.36, 5.67) vs 5.11 (4.54, 5.77) mmol/L, 2.90 (2.45, 3.33) vs 3.23 (2.77, 3.74) mmol/L], and the uric acid level was higher [333.0 (275.5, 397.0) vs 311.0 (257.5, 368.0) μmol/L] (all P<0.001). In regular epidemic prevention period, the levels of body mass index, fasting blood glucose, total cholesterol and LDL-C were significantly higher than those in the early stage of the epidemic [24.0 (21.9, 26.3) vs 23.8 (21.7, 26.1) kg/m 2, 5.18 (4.85, 5.62) vs 4.98 (4.66, 5.42) mmol/L, 5.12 (4.42, 5.76) vs 4.98 (4.36, 5.67) mmol/L, 3.06 (2.59, 3.57) vs 2.90 (2.45, 3.33) mmol/L], while the uric acid was significantly lower [319.0 (265.0, 377.0) vs 333.0 (275.5, 397.0) μmol/L] (all P<0.001). During the early stage of the epidemic, the reduction proportion of unhealthy diet in the home group was significantly higher than that in the outing group (19.5% vs 11.4%), and the increment proportion of exercise in the outing group was significantly higher than that in the home group (5.1% vs 1.6%) (both P<0.05). In regular epidemic prevention period, the increase rate of unhealthy diet in the home group was significantly higher than that in the outing group (26.8% vs 13.0%) ( P<0.001), and there was no significant difference in exercise between the two groups ( P=0.325). During the early stage of COVID-19 epidemic and in the regular epidemic prevention period, unhealthy diet>3 times per week ( OR=3.85, 3.01, 95% CI: 1.74-8.51, 1.41-6.39) was positively correlated with weight gain, and regular exercise ( OR=4.35, 2.61, 95% CI: 2.05-9.23, 1.15-5.91) was positively correlated with weight loss (all P<0.05). Conclusions:During the early stage of COVID-19 epidemic and in the regular epidemic prevention period, the lifestyle in the physical examination population has an impact on body weight and metabolic indicators. In the early stage of the epidemic, unhealthy diet and exercise decreased, and metabolic indicators such as blood glucose and lipids decreased. People with low body weight tend to gain weight. In the regular epidemic prevention period, the subjects′ exercise increased but unhealthy diet also increased, and blood glucose, lipid and body weight elevated significantly.

Objective To explore the effects of vascular risk factors on cognitive function among the elderly in community. Methods A cross-sectional study was conducted in 1 269 elderly people ( aged 65 and over) who were randomly selected from three communities. Through face-to-face interview, cognitive function was assessed by mini-mental state examination(MMSE),and blood samples were collected for labo-ratory examination. Logistic regression analysis was used to analyze the vascular risk factors affecting cogni-tive function. Results Age (( 73. 1 ± 6. 6), ( 71. 3 ± 4. 9),t=4. 603,P<0. 05),education level ( χ2=12. 727,P<0. 05),hypertension (χ2=9. 106,P<0. 05) and LDL-C (χ2=5. 157,P<0. 05) were significantly different in the elderly with or without mild cognitive impairment(MCI). After controlling age,gender and ed-ucation,the logistic regression analysis showed that hypertension(β=0. 378,P=0. 006,OR(95%CI)=1. 44 (1. 10-1. 91)),systolic blood pressure ≥140 mmHg( β=0. 350,P=0. 011,OR( 95% CI)= 1. 42( 1. 08-1. 86),1 mmHg=0. 133 kPa),and high LDL-C( β=0. 355,P=0. 014,OR(95%CI)=1. 43( 1. 08-1. 89)) were the risk factors of MCI in the elderly in the community. Hypertension alone or high LDL-C (β=0. 365, P=0. 029,OR(95%CI)=1. 44(1. 04-2. 00)) alone was risk factor for mild cognitive impairment in the eld-erly in the community. The risk of mild cognitive impairment in the elderly with hypertension and high LDL- C was 2. 00 times higher than that in the healthy elderly ( β=0. 696,P<0. 05,OR( 95%CI)= 2. 00( 1. 36-2. 97)). Conclusion Mild cognitive impairment in the elderly is closely related to hypertension and elevat-ed LDL-C levels. Multiple vascular risk factors can further increase the risk of cognitive impairment.

It is not fully clear why there is a higher contribution of pluripotent stem cells (PSCs) to the chimera produced by injection of PSCs into 4-cell or 8-cell stage embryos compared with blastocyst injection. Here, we show that not only embryonic stem cells (ESCs) but also induced pluripotent stem cells (iPSCs) can generate F0 nearly 100% donor cell-derived mice by 4-cell stage embryo injection, and the approach has a "dose effect". Through an analysis of the PSC-secreted proteins, Activin A was found to impede epiblast (EPI) lineage development while promoting trophectoderm (TE) differentiation, resulting in replacement of the EPI lineage of host embryos with PSCs. Interestingly, the injection of ESCs into blastocysts cultured with Activin A (cultured from 4-cell stage to early blastocyst at E3.5) could increase the contribution of ESCs to the chimera. The results indicated that PSCs secrete protein Activin A to improve their EPI competency after injection into recipient embryos through influencing the development of mouse early embryos. This result is useful for optimizing the chimera production system and for a deep understanding of PSCs effects on early embryo development.

Comfort medical treatment has aroused the attention of all walks of life.Perioperative analgesia will be one of the important components.The analgesic guidelines of American Society of Anesthesiologists (ASA) and anesthesiology are all advocating multi mode analgesia.Transversus abdominis plane (TAP) block is considered to be one of the effective methods of multimode analgesia in the perioperative period.It can provide analgesia for surgical perioperative period,reduce the dosage of opioid after operation and the incidence of adverse reactions.We review the relevant factors on patient selection,anesthetic seletion and clinical efficacy for TAP block by reviewed relative literatures,aiming to provide new methods and ideas for clinical practice.TAP block opens new ideas for perioperative analgesia,and it is a new direction of multimode analgesia during perioperative period.

Objective To explore the clinical value of combined treatment of sufentanil and propofol in children during anesthesia induction.Methods 72 children were selected,and they were randomly divided into three groups by full random allocation method:observation group A,observation group B and control group,24 cases in each group.The observation group A was given intravenous infusion of sufentanil(0.01g · kg-1 · min-1),the observation group B was given intravenous infusion of sufentanil (0.02g · kg-1 · min-1),the control group was given intravenous saline infusion,then given propofol target controlled infusion after 30min.The bispectral index (BIS),propofol effect chamber (EC),OAA/S score and time of induction of anesthesia (LOC) time were recorded in the three groups.Results There was a significant correlation between BIS and propofol EC and OAA/S scores in the three groups,and there was a negative correlation between BIS and propofol EC (r =-0.82,-0.79,-0.88,all P ＜ 0.01).BIS and OAA/S score was positively correlated (r =0.86,0.81,0.89,all P ＜ 0.01).Compared with the control group [(9.11 ± 1.04) min],the LOC time of the observation group A and B [(5.37 ± 0.89) min,(4.49 ± 0.63) min] was significantly shortened (t =13.39,18.61,all P ＜ 0.01).The propofol EC of control group was (2.44 ± 0.5) μg/mL,the propofol EC of the observation group A and B [(1.38 ± 0.35) μg/mL,(1.14 ± 0.27) μg/mL] decreased during anesthesia induction (t =8.40,11.04,all P ＜ 0.01),and the effect of the observation group B was better than that of the observation group A (t =3.95,2.67,all P ＜ 0.05).There was no statistically significant difference in BIS between the observation group A and control group [(70 ± 4) vs.(69 ± 7),t =0.61,P ＞ 0.05].The BIS of observation group B (78 ± 5) was significantly higher than that of the observation group A and control group (t =6.12,5.13,all P ＜ 0.01).Conclusion Sufentanil combined with propofol for anesthesia in children has a synergistic effect,which is beneficial to reduce the amount of propofol EC during anesthesia induction,shorten the time of LOC and enhance the sedative effect of propofol,and it is worthy of further clinical application.

The 13 nm gold nanoparticles ( AuNPs ) were synthesized through the reduction of HAuCl4 by sodium citrate and the glutathione was assembled on the AuNPs. Under the experiment conditions, glutathione-modified AuNPs ( GSH-AuNPs ) with negative charge presented a wine red color owing to the electrostatic repulsion between nanoparticals. Upon the addition of neurogenin 3 ( ngn3 ) peptide, the aggregation of GSH-AuNPs was induced by ngn3 peptide under a certain concentration of salt. The color of AuNPs solution changed from red to blue as a function of the ngn3 peptide concentration. Thus, a rapid detection method for ngn3 peptide using GSH-AuNPs as colorimetric probe was established. The optimal experiment conditions were equilibrium time=10 min, pH=6. 0, CNaCl=100 mmol/L. Under the optimum conditions, the assay showed a linear response range of 20-300 μg/L for the peptide with a detection limit being 8 μg/L and exhibited excellent selectivity for ngn3 peptide.
