Relationship between nutrient-related dietary pattern and mild cognitive impairment in middle-aged and elderly people in 15 provinces of China / 中华流行病学杂志

Objective: To explore the relationship between nutrient-related dietary pattern and mild cognitive impairment (MCI) in middle-aged and elderly people. Methods: A total of 6 444 middle-aged and elderly people aged ≥55 years were selected in 2018 China Health and Nutrition Survey. MCI was evaluated by Mini-Mental State Examination, and the intakes of various foods were obtained by consecutive 3-day 24-hour dietary survey and weighing method. The intakes of various nutrients and total dietary energy were calculated based on the food composition table. Demographic and social information, lifestyle and health status of the respondents were obtained through questionnaire survey and physical measurements. In this study, vitamin C, vitamin E, zinc, iron, copper and selenium were selected as dependent variables. Nutrient-related dietary patterns were extracted by reduced rank regression method, and the relationship between dietary patterns and MCI was analyzed by multivariate logistic regression model. Results: Six dietary patterns were extracted in this study, and dietary pattern 1 with the highest explanatory degree was selected for subsequent analysis. Dietary pattern 1 was characterized by higher intakes of legume products, vegetables, fruits, nuts, pork, aquatic products and plant oil. Multivariate logistic regression analysis showed that the risk of MCI was lower in Q4 dietary score group than in Q1 dietary score group (OR=0.69, 95%CI: 0.49-0.98) in the 55-64 age group. In people with sleep duration of 8 hours per day, the risk of MCI was reduced in Q2, Q3 and Q4 dietary score groups compared with the Q1 dietary score group, with OR values of 0.68 (95%CI: 0.51-0.92), 0.67 (95%CI: 0.49-0.92) and 0.65 (95%CI: 0.45-0.92), respectively. Interaction analysis showed that the risk for MCI increased in those aged 65-74 years and ≥75 years compared with those aged 55-64 years in Q1 dietary score group. However, the risk for MCI decreased in both age groups as dietary pattern scores increased. Compared with those with sleep duration less or more than 8 hours per day in Q1 dietary score group, those with sleep duration of 8 hours per day in Q2 and Q3 dietary score groups had a reduced risk for MCI. Conclusion: Dietary patterns with higher intakes of legume products, vegetables, fruits, nuts, pork, aquatic products, and plant oil are negatively associated with MCI in people aged 55-64 years and those who slept 8 hours per day, and may reduce the risk of MCI with aging.

A Case Series of Olfactory Dysfunction in Imported COVID-19 Patients: A 12-Month Follow-Up Study / 生物医学与环境科学（英文）

Objective@#The scientific community knows little about the long-term influence of coronavirus disease 2019 (COVID-19) on olfactory dysfunction (OD). With the COVID-19 pandemic ongoing worldwide, the risk of imported cases remains high. In China, it is necessary to understand OD in imported cases.@*Methods@#A prospective follow-up design was adopted. A total of 11 self-reported patients with COVID-19 and OD from Xi'an No. 8 Hospital were followed between August 19, 2021, and December 12, 2021. Demographics, clinical characteristics, laboratory and radiological findings, and treatment outcomes were analyzed at admission. We surveyed the patients via telephone for recurrence and sequelae at the 1-, 6-, and 12-month follow-up.@*Results@#Eleven patients with OD were enrolled; of these, 54.5% (6/11) had hyposmia and 45.5% (5/11) had anosmia. 63.6% (7/11) reported OD before or on the day of admission as their initial symptom; of these, 42.9% (3/7) described OD as the only symptom. All patients in the study received combined treatment with traditional Chinese medicine and Western medicine, and 72.7% (8/11) had partially or fully recovered at discharge. In terms of OD recovery at the 12-month follow-up, 45.5% (5/11) reported at least one sequela, 81.8% (9/11) had recovered completely, 18.2% (2/11) had recovered partially, and there were no recurrent cases.@*Conclusions@#Our data revealed that OD frequently presented as the initial or even the only symptom among imported cases. Most OD improvements occurred in the first 2 weeks after onset, and patients with COVID-19 and OD had favorable treatment outcomes during long-term follow-up. A better understanding of the pathogenesis and appropriate treatment of OD is needed to guide clinicians in the care of these patients.

Observations on the Efficacy of Scalp Acupuncture with Strong Stimulation in Treating Intractable Hiccup / 上海针灸杂志

Objective To investigate the efficacy of scalp acupuncture with strong stimulation plus oral hiccup decoction in treating intractable hiccup. Method One hundred patients with intractable hiccup were allocated, using a random number table, to treatment and control groups, 50 cases each. In addition to oral hiccup decoction in the two groups, the treatment group received scalp acupuncture with strong stimulation at the stomach and chest areas and the control group, electroacupuncture, for two courses of treatment. The times to produce the effect and the symptom frequency scores were compared between the two groups. Result After one course of treatment, the cure rate, the cure and marked efficacy rate and the total efficacy rate were 42％, 66％ and 78％, respectively, in the treatment group and 24％, 40％ and 68％, respectively, in the control group. There were statistically significant difference in the cure rate and the cure and marked efficacy rate (P<0.05) but no in the total efficacy rate (P>0.05) between the two groups. After two courses of treatment, the cure rate, the cure and marked efficacy rate and the total efficacy rate were 68％, 78％ and 88％, respectively, in the treatment group and 40％, 60％ and 74％, respectively, in the control group. There were statistically significant difference in the cure rate (P<0.05) but no in the cure and marked efficacy rate and the total efficacy rate (P>0.05) between the two groups. After one and two courses of treatment, there was a statistically significant difference in the hiccup frequency score between the treatment and control groups (P<0.05). The time to produce the effect was 2-5 hrs in the treatment group and 5-8 hrs in the control group. Conclusion The total efficacy rate of scalp acupuncture with strong stimulation for intractable hiccup is not significantly different from that of electroacupuncture, but the cure rate of the former was significantly higher than that of the latter. Scalp acupuncture with strong stimulation can produce a quick effect, reduce the frequency of hiccups and relieve symptoms accompanying hiccup.

Comparison research of transcutaneous bilirubin measurement and serum bilirubin measurement during phototherapy in neonates / 中华护理杂志

Objective To compare the correlation between transcutaneous bilirubin(TcB) measurement and serum bilirubin (TSB) measurement at covered and exposed skin sites during phototherapy in neonates.Methods Two sites of exposed skin and two sites of covered skin were chosen to measure the transcutaneous bilirubin.The serum bilirubin was monitored at admission and during phototherapy,while the transcutaneous bilirubin was tested and recorded at the same time of monitoring the serum bilirubin.Results A total of 112 cases were included from January 29th to April 15th in 2016.At the four monitoring points during phototherapy,the differences between the transcutaneous bilirubin of the two exposed sites and the serum bilirubin were statistically significant (P＜0.01).For the covered site 4,there were no significant differences between transcutaneous bilirubin and serum bilirubin at every test point (P＞0.05).When the serum bilirubin was higher than 307.8 μmol/L (18mg/dl),the serum bilirubin measurement was larger than the transcutaneous bilirubin measurement.Conclusion The transcutaneous bilirubin level of covered skin was more close to serum bilirubin,especially when the covered median skin of the second rib was chosen to monitor the transcutaneous bilirubin.When the serum bilirubin was greater than 307.8 μmol/L(18mg/dl),the transcutaneous bilirubin couldn't represent serum bilirubin quite well.

Effects of Coptidis Rhizoma on Cell Cycle, DNA Damage, and Apoptosis in L929 Murine Fibroblast Cells / 中草药·英文版

Objective Coptidis Rhizoma (CR), a widely used traditional Chinese herbal medicine, is commonly believed to be non-toxic. However, little is known about its cytotoxicity and relevant mechanisms at cellular and genetic levels. The present study was conducted to explore the cytotoxicity of CR and its mechanisms related to cell cycle arrest, DNA damage, cell apoptosis, and mitochondrial membrane potential in L929 murine fibroblast cells. Methods The cells were cultured and treated with different concentration of CR aqueous extract for 24 h. Cell viability was determined by CCK-8 method, morphological changes, and mitochondrial membrane potential were observed with an inverted microscope, cell cycle and cell apoptosis were examined by flow cytometry and DNA damages were detected by comet assay. Results Our results showed that cell viability was significantly decreased in a dose-dependent manner when concentration was higher than 0.2 mg/mL. A concentration above 1 mg/mL altered the cells morphology. Each DNA damage indicator score increased in the groups with the concentration of above 0.1 mg/mL. Cells at G2/M phase, cell apoptosis and mitochondrial membrane potential changed in the 2 mg/mL group. Conclusion Overall, our study suggests that CR at a high dosage exhibits cytotoxicity on L929 cells, which is likely to be the consequences of cell cycle arrest, DNA damage, cell apoptosis and mitochondrial membrane potential reduction.
