Polygonatum sibiricum, as a traditional Chinese medicine with both medicinal and edible properties, has attracted considerable attention due to its functions of nourishing Yin and moistening the lungs, tonifying the spleen and benefiting Qi, and nourishing the kidneys and filling essence. Recent studies have demonstrated that Polygonatum sibiricum plays a significant role in regulating the immune system, effectively enhancing and improving the morphology and function of immune organs, stimulating the proliferation and activation of immune cells, and regulating the secretion and release of immune factors, thereby enhancing the immune function of the body and improving various immune-related diseases. Although a large number of studies have explored the pharmacological effects and mechanisms of P. sibiricum, there has been no systematic review and summary of its immune regulatory activity and mechanisms. Therefore, this article comprehensively reviews the research achievements of P. sibiricum polysaccharides and saponins in the field of immune regulation in recent years, and further sorts out the immune regulatory mechanisms of P. sibiricum in multiple aspects: including increasing the organ index of the spleen and thymus, increasing the number and activity of tumor-suppressive bone marrow hematopoietic stem cells, improving intestinal flora imbalance, regulating the quantity and proportion of T lymphocyte subsets, increasing the level of immunoglobulin, promoting the proliferation of macrophages, enhancing the activity of natural killer cells, increasing the number of white blood cells, and promoting the maturation of dendritic cells, providing a solid theoretical basis and scientific evidence for the research and application of P. sibiricum, and promoting its development and application in traditional Chinese medicine immune enhancers and various functional products.

Background::Hypertension and non-alcoholic fatty liver disease (NAFLD) share several pathophysiologic risk factors, and the exact relationship between the two remains unclear. Our study aims to provide evidence concerning the relationship between hypertension and NAFLD by analyzing data from the National Health and Nutrition Examination Survey (NHANES) 2017-2018 and Mendelian randomization (MR) analyses.Methods::Weighted multivariable-adjusted logistic regression was applied to assess the relationship between hypertension and NAFLD risk by using data from the NHANES 2017-2018. Subsequently, a two-sample MR study was performed using the genome-wide association study (GWAS) summary statistics to identify the causal association between hypertension, systolic blood pressure (SBP), diastolic blood pressure (DBP), and NAFLD. The primary inverse variance weighted (IVW) and other supplementary MR approaches were conducted to verify the causal association between hypertension and NAFLD. Sensitivity analyses were adopted to confirm the robustness of the results.Results::A total of 3144 participants were enrolled for our observational study in NHANES. Weighted multivariable-adjusted logistic regression analysis suggested that hypertension was positively related to NAFLD risk (odds ratio [OR] = 1.677; 95% confidence interval [CI], 1.159-2.423). SBP ≥130 mmHg and DBP ≥80 mmHg were also significantly positively correlated with NAFLD. Moreover, hypertension was independently connected with liver steatosis ( β = 7.836 [95% CI, 2.334-13.338]). The results of MR analysis also supported a causal association between hypertension (OR = 7.203 [95% CI, 2.297-22.587]) and NAFLD. Similar results were observed for the causal exploration between SBP (OR = 1.024 [95% CI, 1.003-1.046]), DBP (OR = 1.047 [95% CI, 1.005-1.090]), and NAFLD. The sensitive analysis further confirmed the robustness and reliability of these findings (all P >0.05). Conclusion::Hypertension was associated with an increased risk of NAFLD.

Objective:To explore the clinical characteristics and genetic variants in three children with late-onset Multiple acyl-Coenzyme A dehydrogenase deficiency (MADD type Ⅲ).Methods:Clinical data of three children diagnosed with late-onset MADD at the Children′s Hospital Affiliated to Zhengzhou University between March 2020 and March 2022 were retrospectively analyzed. All children were subjected to whole exome sequencing (WES), and candidate variants were verified by Sanger sequencing. All children had received improved metabolic therapy and followed up for 1 ~ 3 years.Results:The children had included 2 males and 1 female, and aged from 2 months to 11 years and 7 months. Child 1 had intermittent vomiting, child 2 had weakness in lower limbs, while child 3 had no symptom except abnormal neonatal screening. Tandem mass spectrometry of the three children showed elevation of multiple acylcarnitines with short, medium and long chains. Children 1 and 2 showed increased glutaric acid and multiple dicarboxylic acids by urine Gas chromatography-mass spectrometry (GC-MS) analysis. All children were found to harbor compound heterozygous variants of the ETFDH gene, including a paternal c. 1211T>C (p.M404T) and a maternal c. 488-22T>G variant in child 1, a paternal c. 1717C>T (p.Q573X) and a maternal c. 250G>A (p.A84T) variant in child 2, and a paternal c. 1285+ 1G>A and maternal c. 629A>G (p.S210N) variant in child 3. As for the treatment, high-dose vitamin B2, levocarnitine and coenzyme Q 10 were given to improve the metabolism, in addition with a low fat, hypoproteinic and high carbohydrate diet. All children showed a stable condition with normal growth and development during the follow-up. Conclusion:The compound heterozygous variants of the ETFDH gene probably underlay the muscle weakness, remittent vomiting, elevated short, medium, and long chain acylcarnitine, as well as elevated glutaric acid and various dicarboxylic acids in the three children with type Ⅲ MADD.

Objective:To explore the mediating effect of perceived professional benefits between the humanistic literacy and spiritual care competence among oncology nurses.Methods:From September to October 2022, convenience sampling was used to select 354 oncology nurses from 11 ClassⅢ Grade A hospitals in Sichuan Province, Guangdong Province, and Hubei Province as the research subject. A survey was conducted on oncology nurses using the General Information Questionnaire, Nurses' Perceived Professional Benefit Questionnaire, Nurses' Humanistic Literacy Scale, and the Chinese version of the Spiritual Care Competence Scale (SCCS) . Pearson correlation was used to analyze the relationship between nurses' humanistic literacy, perceived professional benefits, and spiritual care competence. AMOS 26.0 software was used to analyze mediating effects. A total of 354 questionnaires were distributed, and after excluding 7 unqualified questionnaires, 347 valid questionnaires were collected, with a valid response rate of 98.02%.Results:Among 347 oncology nurses, the score of the Chinese version of SCCS was (77.60±19.04) . The total score of the SCCS was positively correlated with the total scores of the Nurses' Humanistic Literacy Scale, the Nurses' Perceived Professional Benefit Questionnaire, and scores of all dimensions, with statistically significant differences ( P<0.01) . Bootstrap test showed that the mediating effect of perceived professional benefits among oncology nurses between humanistic literacy and spiritual care competence was 0.284 [95% CI (0.408, 0.860) ] , accounting for 50.90% of the total effect. Conclusions:The perceived professional benefits of oncology nurses play a partial mediating role between humanistic literacy and spiritual care competence. We should strengthen training on the humanistic literacy of oncology nurses, enhance their perceived professional benefits, form a virtuous cycle of employment, and thereby improve their spiritual care competence.

OBJECTIVE To explore the influence of Zingiber officinale and processed Z. officinale on pharmacodynamic indexes and intestinal flora on gastric ulcer rats with spleen -stomach deficiency and cold type before and after processing with sand . METHODS The SD rats were randomly divided into normal group ,model group ,positive control group (Compound tianqi weitong capsule 0.45 g/kg),Z. officinale high-dose(15.0 g/kg)and low -dose(7.5 g/kg)groups,processed Z. officinale high- dose(15.0 g/kg)and low -dose(7.5 g/kg)groups,with 10 rats in each group . The rat model of gastric ulcer with spleen -stomach deficiency and cold type was established by intragastric administration of vinegar (day 1-10)and absolute ethanol (day 11). Administration groups were given relevant liquid intragastrically ,and normal group and model group were given water intragastrically(day 5-10). One hour after intragastric administration of absolute ethanol ,blood was taken from the femoral artery of rats ,the serum contents of motilin (MTL),gastrin(GAS),epidermal growth factor (EGF)as well as 4 items of blood coagulation [activated partial thromboplastin time (APTT),prothrombin time (PT),thrombin time (TT),fibrinogen(FIB)] were detect. The ulcer index and inhibition rate of ulcer in gastric tissue were calculated . The pathological changes of gastric tissue were observed,and the number and area of erosions were recorded . The diversity of gut microbiota in fecal samples of rats was detected . RESULTS Compared with model group ,the contents of MTL (except for processed Z. officinale low-dose group ),GAS(except for processed Z. officinale low-dose group ),EGF(except forofficinale groups) and FIB (except for Z. officinale groups),inhibitory rate of ulcer (only positive control group )were all increased significantly (P<0.05). APTT(except for Z. officinale groups),PT(only processed Z. officinale high- dose group ),TT(except for Z. officinale groups),ulcer index (except for Z. officinale groups),the number (except for Z. officinale groups)and area of erosions (except for Z. officinale groups)were shortened and decreased significantly (P<0.05); improvement effects of processed Z. officinale were better than those of the same dose of Z. officinale on EGF ,4 items of blood coagulation(except for PT ,TT,FIB of processed Z. officinale low-dose group ),ulcer index (except for processed Z. officinale low-dose group )and inhibitory rate of ulcer (P<0.05). Compared with model group ,α diversity indexes as ACE ,Shannon and Simpson of intestinal microorganisms in rats were increased significantly in processed Z. officinale group;the relative abundance of Proteobacteria was decreased significantly in processed Z. officinale group,while that of Bacteroidetes was increased significantly (P<0.05); the relative abundance of Limosilactobacillus was decreased significantly in Z. officinale group (P<0.05). CONCLUSIONS Z. officinale and processed Z. officinale can improve the symptoms of spleen -stomach deficiency and cold ,and enhance gastrointestinal function by increasing the content of GAS and MTL . Processed Z. officinale can significantly inhibit gastric ulcer of spleen -stomach deficiency and cold type ,which is related to the promotion of mucosal protection and repair ,improvement of coagulation functionand adjustment of gut microbiotadisorder .

Objective:To investigate the status of postoperative sore throat and hoarseness in patients undergoing general anesthesia with double-lumen endotracheal intubation and analyze its influencing factors.Methods:Using the convenient sampling method, a total of 129 patients with double-lumen endotracheal intubation who underwent elective surgery in a Class Ⅲ Grade A general hospital in Wuhan in Hubei Province from July to December 2020 were selected as the research objects. The general information questionnaire, Visual Analogue Scale (VAS), Labial and Tongue Mucosa Scale and Hoarse Voice Scale were used to investigate the patients.Results:The incidence of sore throat in 129 patients with double-lumen endotracheal intubation at 1, 6, 24, 48 and 72 hours after surgery were 68.22%, 44.96%, 76.74%, 64.34% and 48.84%, respectively. Among them, the incidences of sore throat in resting state were respectively 10.9%, 6.2%, 1.6%, 0 and 1.6%, incidences of sore throat in swallowing state were respectively 18.6%, 8.5%, 3.1%, 0 and 0, and the incidences of hoarseness were respectively 66.67%, 45.74%, 78.29%, 65.89% and 48.84%. There were statistically significant differences in the occurrence of hoarseness in patients of different ages and preoperative fasting time 1 hour after extubation ( t=2.499, 2.106; P<0.05). The VAS scores of patients with hoarseness in resting state and swallowing state were higher than those in patients without hoarseness, and the differences were statistically significant ( t=3.688, 2.818; P<0.01). Correlation analysis showed that hoarseness was negatively correlated with the condition of lip and tongue mucosa ( r=-0.309, P<0.01) . Conclusions:The incidence of postoperative throat pain in patients undergoing general anesthesia with double-lumen endotracheal intubation is high. With the extension of time, pain can be gradually relieved. The self-healing effect of hoarseness over time is not ideal. Advanced age, prolonged water fasting before operation and dry lip and tongue mucosa are the influencing factors of postoperative sore throat. Early identification and effective measures should be given in nursing evaluation to reduce the occurrence of postoperative sore throat.

Objective To investigate the sleep quality of older adults in Shaoxing City and to examine its influencing factors. Methods Based on a cross-sectional questionnaire survey, a cluster sampling method was adopted to collect participants. Five villages were chosen randomly from 20 in the Yuecheng district of Shaoxing. The respondents were adults aged more than 60 years in the 5 villages. In total,1 303 adults participated,including 603 men and 700 women,and the average age was(70.99±7.38). The information related to sociodemographic factors,health status,sleep characteristics,and behavioral and lifestyle factors were collected.A chi-square test and variance analysis were used to compare sleep quality and sleep duration among participants. An ordinal regression model was adopted to examine the factors influencing sleep quality. Results One hundred and ninety-six (15.0%) older adults reported that sleep quality was always bad during the past year, 180(13.8%)reported that sleep quality was bad occasionally, and 927(71.1%)reported that sleep quality was good every day.The average sleep duration of participants was(6.64±1.38)h per night,and sleep durations for older adults who reported that sleep quality was always bad, bad occasionally, and good every day were (4.21 ± 1.13) h, (6.12 ± 1.40) h, and (7.26 ± 1.39) h, respectively,and older adults with poor sleeping quality had a shorter sleep duration(F=421.828,P<0.001). Being a woman, more than 80 years old, not working, and taking sleeping pills were risk factors for poor sleep quality with ORs (95% CI) of 1.492 (1.132-1.964), 1.564 (1.108-2.206), 1.331 (1.015-1.747), and 14.614(7.164-29.844),respectively.Conclusions Elderly individuals in Shaoxing had poor sleep quality. The sleep quality of those who were women, were oldest and took sleeping pills is cause for concern. Encouraging them to engage in work may improve their sleeping status.
