ObjectiveTo explore the correlation between general anesthesia and mild cognitive impairment in older adults so as to provide new ideas for early prevention and timely intervention of mild cognitive impairment(MCI). MethodsBased on the baseline survey of the Hubei memory and aging cohort study(2018-2023), the participants completed a thorough neuropsychological assessment and physical examination, and self-reported a history of general anesthesia and surgery. The association of general anesthesia and MCI in the elderly was analyzed using the logistic regression model. In addition, the stratification and interaction analysis of anesthesia history, anesthesia number and physical intellectual exercise were conducted separately. ResultsA total of 5 069 older adults aged 65 and above were included in this study, including 3 692 city dwellers and 1 377 rural people, among whom were 2 584 women (51%). Out of the 1 472 participants with history of general anesthesia, 249 people (17.4%) had MCI. After controlling for confounding factors, there was a 39.6% increased risk of MCI in older adults who underwent general anesthesia [OR=1.396,95%CI(1.169,1.668),P<0.001], suggesting that general anesthesia may be an independent influence on MCI. For the older adults who had one general anesthesia [OR=1.235,95%CI(1.001,1.523),P=0.049], two general anesthesia [OR=1.779,95%CI (1.292,2.450),P<0.001], and three OR more general anesthesia [OR=2.395,95%CI (1.589,3.610),P<0.001], their risks of MCI were increased by 23.5%, 77.9%, and 139.5%, respectively. Compared with the older adults without a history of general anesthesia who did not exercise, the risk of developing MCI was significantly negatively correlated with the exercise group, cognitive exercise group, and combined exercise and cognitive exercise groups (all P<0.001). The risk of developing MCI in the exercise group was 60.2% of that in the no exercise group [OR = 0.602, 95% CI(0.456, 0.795)], the risk in the cognitive exercise group was 42.4% of that in the no exercise group [OR = 0.424, 95% CI(0.294, 0.613)], and the risk in the combined exercise and cognitive exercise group was 27.0% of that in the no exercise group [OR = 0.270, 95% CI (0.208, 0.353)]. In the older adults with a history of general anesthesia, compared with the no exercise group, the risk of developing MCI was significantly negatively correlated with the cognitive exercise group and the combined exercise and cognitive exercise group (all P < 0.05). The risk of developing MCI in the cognitive exercise group was 47.7% of that in the no exercise group [OR=0.477, 95% CI (0.256,0.892)], the risk in the combined exercise and cognitive exercise group was 34.5% of that in the no exercise group [OR=0.345, 95% CI (0.220, 0.540)], while the risk in the exercise-only group did not show a significant difference. ConclusionThe risk of MCI increased significantly in older adults with a history of general anesthesia, and this risk increased with the times of anesthesia. Physical and mental exercise reduces the risk of MCI. it is recommended that older adults with a history of anesthesia incorporate physical and mental exercise into their daily lives to prevent mild cognitive impairment.

ObjectiveTo observe the clinical efficacy and safety of Dizhuo Huayu prescription combined with catgut embedding therapy in patients with nonalcoholic steatohepatitis (NASH) and dyslipidemia and explore the effect of the combined therapy on inflammatory cytokines interleukin (IL)-18 and IL-1β. MethodsA total of 82 patients with NASH and dyslipidemia from the Gastroenterology Department of the First Affiliated Hospital of Henan University of Chinese Medicine were randomly divided into a control group and a treatment group, with 41 patients in each group. The control group received Polyene Polyenylphosphatidylcholine Capsules, while the treatment group received Dizhuo Huayu prescription granules combined with catgut embedding. The treatment duration was 24 weeks for both groups. At weeks 0, 12, and 24, the traditional Chinese medicine (TCM) syndrome score, body mass index (BMI), liver fat content assessed by Fibroscan (CAP value), the level of alanine transaminase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and free fatty acid (FFA), and the expression of inflammatory cytokines IL-18 and IL-1β in serum were observed. Adverse reactions in both groups were recorded. ResultsA comparison of the comprehensive therapeutic effects between the two groups after 24 weeks of treatment revealed that the total effective rate was 62.16% (23/37) in the control group and 85.71% (30/35) in the treatment group, with a statistically significant difference (χ2 = 5.14, P<0.05). At weeks 12 and 24 after treatment, the TCM syndrome score, BMI, CAP value, TC, TG, LDL-C, and FFA were all significantly lower in both groups compared to pre-treatment levels, while the HDL-C level significantly increased (P<0.05). The effect was better at week 24 (P<0.05) than at week 12 (P<0.05), and the treatment group showed better outcomes than the control group at weeks 12 and 24 after treatment (P<0.05). After 24 weeks of treatment, both groups exhibited significant reductions in IL-18 and IL-1β levels (P<0.05). The treatment group demonstrated superior efficacy compared to the control group after treatment (P<0.05). Both groups experienced decreases in ALT, AST, and GGT levels after treatment (P<0.05). However, there were no statistically significant differences between the 12-week and 24-week post-treatment values within each group, nor were there significant differences between the two groups. No significant adverse reactions were observed in both groups. ConclusionThe Dizhuo Huayu prescription combined with catgut embedding therapy is safe and effective in treating patients with NASH and dyslipidemia, exhibiting hepatoprotective, anti-inflammatory, lipid-regulating, and weight-reducing effects.

Objective:To explore the prevalence, clinical features, genetic characteristics and prognosis of Citrin deficiency in Henan province of China.Methods:A total of 986 565 neonates screened by tandem mass spectrometry at the Third Affiliated Hospital of Zhengzhou University from January 2013 to December 2021 were retrospectively analyzed. Analysis of SLC25A13 gene variants and parental verification were carried out for neonates suspected for Citrin deficiency by next-generation sequencing. The clinical, biochemical and genetic characteristics of Citrin deficiency patients were integrated to guide the diet treatment and follow up the growth and development. Paired- t test was used to compare the amino acid levels in the peripheral blood samples before and after the treatment. Results:Nine cases of Citrin deficiency were diagnosed among the 986 565 neonates. Specific elevation of citrulline was observed in all of the 9 cases. Six variants were detected by genetic sequencing, among which c. 852_855delTATG, c. 615+ 5G>A, c. 550C>T and IVS16ins3kb were known pathogenic variants, whilst c. 1111_1112delAT and c. 837T>A were unreported previously. The detection rate for c. 852_855delTATG was the highest (61.6%, 11/18), followed by IVS16ins3kb (16.7%, 3/18). The clinical symptoms of all patients were relieved after the treatment, and the blood amino acid profile and biochemical parameters were significantly improved by gradually falling within the normal range. By June 2022, all patients had shown a good prognosis.Conclusion:The prevalence of Citrin deficiency among neonates from Henan Province by tandem mass spectrometry is 1/109 618, and the carrier rate for the pathogenic variants of the SLC25A13 gene was 1/166. The c. 852_855delTATG may be a hot spot variant among the patients. Discovery of the novel variants has enriched the mutational spectrum of the SLC25A13 gene. Above results have provided a basis for the early diagnosis, treatment, prognosis and genetic counseling for the affected families.

Objective:To investigate the clinical, imaging, etiological and prognostic features of patients with infarctions in different locations of the medulla oblongata.Methods:Patients with acute medullary infarction hospitalized at Tianjin Huanhu Hospital from July 2017 to July 2022 were included. The risk factors, clinical manifestation, stroke mechanism and 90-day prognosis of these patients were analyzed retrospectively.Results:Among the 256 patients enrolled, 150 (58.6%) had lateral medullary infarction (LMI), 106 (41.4%) had medial medullary infarction (MMI). The most frequent clinical manifestation of patients with LMI was dizziness (84.7%,127/150). And motor disorders (83.0%,88/106) was the most frequent clinical manifestation of patients with MMI. LMI lesions were mostly located in the middle (42.7%,64/150) and MMI lesions were mostly located in the upper (60.4%,64/106) medulla oblongata, with statistically significant difference (χ 2=47.53, P<0.001). Large artery atherosclerosis (LAA) was the main stroke mechanism in LMI and MMI [57.3%(86/150) vs 56.6%(60/106)]. Early neurological deterioration was more common in MMI (25.5%,27/106) and less common in LMI (7.3%,11/150), with statistically significant difference (χ 2=16.17, P<0.001). At discharge, more patients with MMI showed poor prognosis in short term [45.3% (48/106) vs 24.0% (36/150), with statistically significant difference (χ 2=12.76, P<0.001)] and even long term at 90-day follow-up [33.0% (35/106) vs 12.7% (19/150), also with statistically significant difference (χ 2=15.48, P<0.001)] than those with LMI. A total of 10 patients (4.0%, 10/256) developed respiratory failure during hospitalization, including 7 patients with LMI (4.7%, 7/150) and 3 patients with bilateral MMI (2.8%,3/106). Early neurological deterioration ( OR=3.38, 95% CI 1.25-9.10, P=0.016) and LAA (compared with small artery occlusion) ( OR=3.08, 95% CI 1.13-8.37, P=0.028) were independent risk factors for poor prognosis in MMI. Age ( OR=1.01, 95% CI 1.01-1.17, P=0.026) and early neurological deterioration ( OR=20.19, 95% CI=2.63-155.06, P=0.004) were independently correlated with poor outcome in LMI. Conclusions:LMI and MMI had similar etiology and significant differences in clinical manifestations, early neurological deterioration and prognosis. Further classification of medullary infarction was of great significance for diagnosis, treatment and prognosis evaluation.

OBJECTIVE:
To evaluate the clinical value of Dachengqi decoction in the treatment of sepsis complication with gastrointestinal dysfunction via gastric antrum cross-sectional area (CSA) measured by bedside ultrasound.
METHODS:
A parallel group randomized controlled trial was conducted. A total of 80 patients with sepsis with gastrointestinal dysfunction admitted to the Second Affiliated Hospital of Nanjing University of Chinese Medicine from January 2021 to October 2022 were enrolled. According to whether patients agree to use Dachengqi decoction after admission, all patients were divided into Dachengqi decoction group (observation group) and conventional treatment group (control group) by 1 : 1 randomization, each group has 40 patients. Both groups were treated with fluid resuscitation, anti-infection, maintaining stable respiratory circulation, early nourishing feeding, promoting gastrointestinal motility, and regulating intestinal flora. The observation group was treated with Dachengqi decoction on the basis of western medicine, 30 mL decoction was taken in the morning and evening. Both groups were treated for 7 days. The CSA of the two groups was measured by bedside ultrasound before and after treatment. The gastric residual volume (GRV1 and GRV2) were calculated by formula and traditional gastric tube withdrawal method. The gastrointestinal dysfunction score, acute physiology and chronic health evaluation II (APACHE II), intraperitoneal pressure (IAP), serum preprotein (PA), albumin (Alb), white blood cell count (WBC), procalcitonin (PCT), hypersensitivity C-reactive protein (hs-CRP), length of intensive care unit (ICU) stay and incidence of aspiration were detected to evaluate the clinical efficacy of Dachengqi decoction, the correlation and advantages and disadvantages between CSA measured by bedside ultrasound and other evaluation indicators of gastrointestinal dysfunction in sepsis were also analyzed.
RESULTS:
There were no significant differences in the indicators before treatment between the two groups, which were comparable. In comparison with the pre-treatment period, CSA, GRV, gastrointestinal dysfunction score, APACHE II score, IAP, WBC, PCT, and hs-CRP of the two groups after treatment were significantly decreased, PA and Alb were significantly increased, and the observation group decreased or increased more significantly than the control group [CSA (cm2): 4.53±1.56 vs. 6.04±2.52, GRV1 (mL): 39.85±8.21 vs. 53.05±11.73, GRV2 (mL): 29.22±5.20 vs. 40.91±8.97, gastrointestinal dysfunction score: 0.87±0.19 vs. 1.35±0.26, APACHE II score: 11.54±3.43 vs. 14.28±3.07, IAP (cmH2O, 1 cmH2O ≈ 0.098 kPa): 9.79±2.01 vs. 13.30±2.73, WBC (×109/L): 9.35±1.24 vs. 12.35±1.36, PCT (μg/L): 3.68±1.12 vs. 6.43±1.45, hs-CRP (mg/L): 24.76±5.41 vs. 46.76±6.38, PA (mg/L): 370.29±45.89 vs. 258.33±34.58, Alb (g/L): 38.83±5.64 vs. 33.20±4.98, all P < 0.05]. The length of ICU stay (days: 10.56±3.19 vs. 14.24±3.45) and incidence of aspiration (12.5% vs. 25.0%) were lower than those in the control group (both P < 0.05). Correlation analysis showed that CSA measured by bedside ultrasound was positively correlated with GRV2, gastrointestinal dysfunction score, APACHE II score, and IAP (r values were 0.84, 0.78, 0.75, 0.72, all P < 0.01) and negatively correlated with PA and Alb (r values were -0.64 and -0.62, both P < 0.01).
CONCLUSIONS
The Dachengqi decoction can significantly improve the clinical symptoms of septic patients with gastrointestinal dysfunction, reduce systemic inflammatory response, improve nutritional status, and shorten ICU hospital stay. Bedside ultrasound monitoring of CSA is a simple, accurate and effective means to evaluate gastrointestinal dysfunction, which is worthy of further clinical promotion.

ObjectiveTo compare the neuropsychological development of infants with different types of morphologic cranial deformities. MethodsA total of 954 children aged 0 to 18 months who came to Beijing Children's Hospital from January, 2020 to August, 2021 for cranial measurement and neuropsychological development measurement were selected. They were divided into brachycephaly group, plagiocephaly group, asymmetric brachycephaly group, scaphocephaly group and normal group according to the cranial measurement. The development quotient (DQ) was calculated from Children Neuropsychological Development Scale (0-6). ResultsThere were 449 cases in the normal group, 94 cases in the brachycephaly group, 201 cases in the plagiocephaly group, 82 cases in the asymmetric brachycephaly group and 128 cases in the scaphocephaly group. The detection rate of Developmental Edge and Delay (DQ < 85) for gross motor area was the most in brachycephaly group (60.6%), and it was the most for fine motor (64.6%), language (45.1%), adaption (51.2%) and social behavior areas (48.8%) in the asymmetrical brachycephaly group. The DQ was different among the five groups for all the areas except the language area (F > 14.835, P < 0.001); compared with the normal group, DQ decreased for all the four areas in all the groups except the scaphocephaly group; DQ of the areas of gross motor, fine motor and adaption was more in the plagiocephaly group than in the asymmetric brachycephaly group (P < 0.05), while DQ of the areas of gross motor and fine motor was more in the plagiocephaly group than in the brachycephaly group (P < 0.05). Linear regression analysis showed that, DQ negative linear correlated with the cephalic ratio and cranial vault asymmetry index (|B| > 0.967, P < 0.05). ConclusionAmong four kinds of cranial malformation in infants, the neuropsychological development of the scaphocephaly group is almost normal, and somehow delays for brachycephaly, plagiocephaly and asymmetric brachycephaly, especially in the aspects of gross motor, fine motor, adaption and social behavior. The more serious the cranial deformity, the greater the risk of developmental delay in each functional area.

Objective:
To investigate the current situation and related factors of the ecological environment and health literacy level of medical college students in Shiyan City, so as to propose relevant countermeasures and suggestions for improvement in these domains.
Methods:
From May to June 2023, 1 312 medical students from Hubei University of Medicine in Shiyan City were selected by accidental sampling to investigate the level and influencing factors of the ecological environment and health literacy among this population. The Chi square test and binary multivariate Logistic regression analysis were performed to analyze the different characteristics and main influencing factors of the ecological environment and health literacy levels in this population.
Results:
The level of the ecological environment and health literacy level among medical students in Shiyan City was 24.3%. Different levels of ecological environmental and health literacy were observed among medical students by gender, grade, major and ethnicity ( χ 2=5.13, 54.87 , 64.71, 5.99, P <0.05). Higher rates were also observed among public health major students than among students of other majors. The first three classification literacy levels consisting of basic literacy, basic knowledge, and basic skills were 4.6%, 49.5 % and 50.4%, respectively. The possession rates of six secondary classification indicators were as follows:basic cognition ( 53.2 %), basic attitudes (34.5%), scientific knowledge (3.0%), behavioral knowledge (22.5%), cognitive skills (59.5%) and operational skills (48.6%). The results of multivariate Logistic regression showed that ethnic minorities and biomedical majors were negatively correlated with medical students ecological environment and health literacy ( OR =0.61,0.52), while female students, public health majors, sophomores and seniors were positively correlated with medical students ecological environment and health literacy ( OR=1.44, 1.95, 2.16, 2.24, P <0.05).
Conclusions
The overall level of ecological environment and health literacy among medical students in Shiyan City is low. Schools should popularize environmental health knowledge from different perspectives in order to improve the overall literacy level of environmental health literacy among medical students.

Objective To investigate the effect of Huatan Qushi Huoxue prescription on the ultrastructure of hepatocyte mitochondria in a rat model of nonalcoholic steatohepatitis (NASH). Methods A total of 48 male Sprague-Dawley rats were randomly divided into blank group, model group, Yishanfu group, and Huatan Qushi Huoxue prescription group, with 12 rats in each group. The rats in the model group and the drug groups were administered and modeled since week 2; the rats in the blank group were given normal diet, and those in the other three groups were given high-fat diet. Based on dose conversion between human and animal, the equivalent dose of Huatan Qushi Huoxue prescription was 1.26 g/100 g body weight, and the equivalent dose of polyene phosphatidylcholine capsules (Yishanfu) was 0.014 18 g/100 g body weight. The rats in the model group were given 0.9% sodium chloride by gavage, those in the Yishanfu group were given polyene phosphatidylcholine suspension by gavage, and those in the traditional Chinese medicine group were given the granules of Huatan Qushi Huoxue prescription by gavage, once a day for 10 consecutive weeks. A transmission electron microscope was used to observe liver ultrastructure and perform a quantitative analysis. A one-way analysis of variance was used for comparison of continuous data between multiple groups; for further pairwise comparison, the least significant difference t -test was used for data with homogeneity of variance, and the Dunnett's T3 was used for data with heterogeneity of variance. Results The model group had a large number of lipid droplets accumulated in hepatocytes, changes in mitochondrial morphology and structure, and reductions in the number of mitochondria and endoplasmic reticulum. The Huatan Qushi Huoxue prescription group had a significant reduction in lipid droplets in hepatocytes and significant increases in the number of mitochondria and endoplasmic reticulum compared with the model group, with intact mitochondrial membrane and structure. The Yishanfu group had a reduction in lipid droplets in hepatocytes, an increase in the number of mitochondria, and a reduction in the number of endoplasmic reticulum, with relatively intact mitochondrial membrane and structure. The quantitative analysis showed that compared with the blank group, the model group had a significant increase in the area of lipid droplets and a significant reduction in mitochondria, with a significant difference in mitochondrial density between the two groups (all P < 0.01); after drug intervention, the Yishanfu group had a significant reduction in the area of lipid droplets and a significant increase in the number of mitochondria, with a significant difference in mitochondrial density between the Yishanfu group and the model group (all P < 0.01); compared with the Yishanfu group, the traditional Chinese medicine group had a significantly greater reduction in the area of lipid droplets and a significant increase in the number of mitochondria, with a significant difference in mitochondrial density between the two groups (all P < 0.05). Conclusion Huatan Qushi Huoxue prescription can improve lipid accumulation, increase mitochondrial density, and protect mitochondrial structure and function, with a better clinical effect than Yishanfu.

Emerging evidence indicates that the gut microbiome contributes to the host immune response to infectious diseases. Here, to explore the role of the gut microbiome in the host immune responses in COVID-19, we conducted shotgun metagenomic sequencing and immune profiling of 14 severe/critical and 24 mild/moderate COVID-19 cases as well as 31 healthy control samples. We found that the diversity of the gut microbiome was reduced in severe/critical COVID-19 cases compared to mild/moderate ones. We identified the abundance of some gut microbes altered post-SARS-CoV-2 infection and related to disease severity, such as Enterococcus faecium, Coprococcus comes, Roseburia intestinalis, Akkermansia muciniphila, Bacteroides cellulosilyticus and Blautia obeum. We further analyzed the correlation between the abundance of gut microbes and host responses, and obtained a correlation map between clinical features of COVID-19 and 16 severity-related gut microbe, including Coprococcus comes that was positively correlated with CD3+/CD4+/CD8+ lymphocyte counts. In addition, an integrative analysis of gut microbiome and the transcriptome of peripheral blood mononuclear cells (PBMCs) showed that genes related to viral transcription and apoptosis were up-regulated in Coprococcus comes low samples. Moreover, a number of metabolic pathways in gut microbes were also found to be differentially enriched in severe/critical or mild/moderate COVID-19 cases, including the superpathways of polyamine biosynthesis II and sulfur oxidation that were suppressed in severe/critical COVID-19. Together, our study highlighted a potential regulatory role of severity related gut microbes in the immune response of host.
