Objective To investigate the correlation between thyroid hormone levels and cognitive function in schizophrenia(SCZ)patients with metabolic syndrome(MetS),as well as the mediating role of thyroid hormones in the relationship between MetS-related indicators and cognitive function.Methods A cross-sectional trial was conducted on 120 SCZ inpatients and outpatients(40 cases of MetS and 80 cases of non-MetS)and 80 healthy controls admitted in the Chongqing Mental Health Center from August 2023 to December 2024.Thyroid function indicators[Thyroid-stimulating hormone(TSH),triiodothyronine(T3),thyroxine(T4),free triiodothyronine(FT3),and free thyroxine(FT4)],MetS-related parameters[blood glucose,triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),and waist circumference],Positive and Negative Syndrome Scale(PANSS)score,and Montreal Cognitive Assessment(MoCA)scores were collected.One-way ANOVA or Kruskal-Wallis rank sum test was applied to analyze the differences among the 3 groups,and LSD test or Bonferroni correction was performed for post hoc analysis.Pearson correlation analysis was conducted to assess the relationship between thyroid hormone levels and metabolic parameters as well as cognitive/clinical scale scores(MoCA,PANSS)in the MetS group.Results The MetS group exhibited significantly lower FT4 level(P<0.05)and MoCA score(P=0.001),but higher TSH level(P<0.05)and PANSS negative symptom score(P<0.001)when compared to the non-MetS group.Correlation analysis indicated that in the MetS group,TSH level was positively correlated with TG(r=0.672,P<0.001)and PANSS negative symptom score(r=0.458,P<0.05),and negatively with HDL-C(r=-0.377,P=0.017)and MoCA score(r=-0.667,P<0.001);FT4 level was positively correlated with MoCA score(r=0.534,P<0.001).In the non-MetS group,TSH level was positively correlated with PANSS negative symptom score(r=0.267,P=0.017)and negatively with HDL-C(r=-0.236,P=0.036),T3 was positively with waist circumference(r=0.268,P=0.017).No correlation was observed in FT4 level with HDL-C(r=-0.207,P=0.067)or MoCA score(r=0.216,P=0.055).Mediation analysis revealed that TSH partially mediated the association between TG and MoCA score,with a mediation effect accounting for 29.91%of the total effect.The mediating effect was not significant in the non-MetS group.Conclusion Abnormal elevation of TSH may serve as a critical link between MetS and cognitive impairment in SCZ patients,which providing novel insights into the mechanisms underlying cognitive dysfunction in the patients.

Paying for TCM according to the value of efficacy is an intrinsic requirement for establishing an effective and efficient diversified medical insurance payment method, and is also an important measure to support the inheritance, innovation and development of TCM. This study used text mining and PMC index model to quantitatively analyze and evaluate the texts of 20 special policies on payment based on efficacy value in TCM. It was found that there were 6 excellent policies, 14 acceptable policies, and there were no undesirable policies or perfect policies; overall, the average policy PMC index was 6.94, and the average provincial policy was 7.06, which was higher than the prefecture-level average of 6.27; the overall quality of special policies of TCM based on efficacy value was relatively high, but there was still much room for improvement in terms of policy timeliness, policy evaluation, policy measures, policy tools, and balance of policy design between provinces and cities.

Based on the view of the correspondence between nature and man in traditional Chinese medicine TCM),TCM master Professor Xia Guicheng attaches importance to the transformation of yin and yang in the female reproductive rhythm and created the"menstrual cycle rhythm regulation method".Women's special physiological phenomena are manifested in the periodic rhythm.The bi-ological clock is the internal mechanism for producing and regulating the physiological behavior and laws of organisms.The biological clock gene is widely expressed in ovarian granulosa cells,theca cells and corpus luteum cells,and is involved in the synthesis of ster-oid hormones,differentiation of follicular somatic cells,follicle development and ovulation and other physiological processes,playing an important role in female reproductive endocrine.Circadian rhythm disorders can lead to reproductive diseases such as menstrual disor-ders,ovarian dysfunction,and endocrine metabolic disorders.There are similarities between TCM time medicine and the biological clock rhythm system.Fully understanding the impact of the biological clock on female ovarian function,revealing its scientific connota-tion,and clarifying the regulatory method and mechanism will have a positive role in resisting reproductive disorders and optimizing fer-tility.

Objective:To investigate the dynamic changes of diaphragm and limb skeletal muscle in patients with sepsis by bedside ultrasound and their correlation with the ratio of blood urea/creatinine ratio (UCR) in 7 days after intensive care unit (ICU) admission.Methods:A prospective observational study was conducted. A total of 55 patients with sepsis admitted to ICU of General Hospital of Ningxia Medical University from June 2022 to February 2023 were selected as the research objects. General information, laboratory indicators [urea, serum creatinine (SCr), and UCR] on days 1, 4, and 7 of ICU admission, and prognostic indicators were observed. Bedside ultrasound was used to assess the dynamic changes of diaphragm morphology [including diaphragmatic excursion (DE), end-inspiratory diaphragm thickness (DTei), and end-expiratory diaphragm thickness (DTee)] on days 1, 4, and 7 of ICU admission, as well as limb skeletal muscle (quadriceps femoris) morphology [including rectus femoris-muscle layer thickness (RF-MLT), vastus intermedius-muscle layer thickness (VI-MLT), and rectus femoris-cross sectional area (RF-CSA)]. Diaphragm thickening fraction (DTF) and RF-CSA atrophy rate were calculated, and the incidence of diaphragm and limb skeletal muscle dysfunction was recorded. The correlation between ultrasound morphological parameters of diaphragm and quadriceps and UCR at each time points in 7 days after ICU admission was analyzed by Pearson correlation.Results:A total of 55 patients with sepsis were included, of which 29 were in septic shock. As the duration of ICU admission increased, the incidence of diaphragm dysfunction in patients with sepsis increased first and then decreased (63.6%, 69.6%, and 58.6% on days 1, 4, and 7 of ICU admission, respectively), while the incidence of limb skeletal muscle dysfunction showed an increasing trend (54.3% and 62.1% on days 4 and 7 of ICU admission, respectively), with a probability of simultaneous occurrence on days 4 and 7 of ICU admission were 32.6% and 34.5%, respectively. The UCR on day 7 of ICU admission was significantly higher than that on day 1 [121.77 (95.46, 164.55) vs. 97.00 (70.26, 130.50)], and RF-CSA atrophy rate on day 7 was significantly higher than that on day 4 [%: -39.7 (-52.4, -22.1) vs. -26.5 (-40.2, -16.4)]. RF-CSA was significantly lower on day 7 compared to day 1 [cm 2: 1.3 (1.0, 2.5) vs. 2.1 (1.7, 2.9)], with all differences being statistically significant (all P < 0.05). Pearson correlation analysis showed that RF-CSA on day 7 of ICU admission was negatively associated with the UCR on the same day ( r = -0.407, P = 0.029). Conclusions:Diaphragmatic dysfunction in patients with sepsis occurred early and can be improved. Limb skeletal muscle dysfunction occurred relatively later and progresses progressively. The RF-CSA on day 7 of ICU admission may be a reliable measure of limb skeletal muscle dysfunction in patients with sepsis, can be an indicator of early identification and diagnosis of ICU-acquired weakness (ICU-AW). Continuous loss of muscle mass occurring in septic patients is mainly associated with persistent organismal catabolism, and undergoes significant changes around a week in ICU.

Objective:To investigate the influencing factors of textbook outcomes in liver surgery (TOLS) after radical resection of gallbladder carcinoma.Methods:The retrospective case-control study was conducted. The clinicopathological data of 530 patients who underwent radical resection of gallbladder carcinoma in 15 medical centers, including the First Affiliated Hospital of Army Medical University et al, from January 2014 to January 2020 were collected. There were 209 males and 321 females, aged (61±10)years. Patients underwent radical resection of gallbladder carcinoma, including cholecystectomy, hepatectomy, invasive bile duct resection, and lymph node dissection. Observation indicators: (1) situations of TOLS; (2) influencing factors of TOLS. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the Mann-Whitney U test. The univariate analysis was conducted using the corresponding statistical methods based on data type, and variables with P<0.10 were included in multivariate analysis. Multivariate analysis was conducted using the Logistic stepwise regression model. Results:(1) Situations of TOLS. All 530 patients underwent radical resection of gallbladder carcinoma, and there were 498 cases achieving R 0 resection, 508 cases without ≥grade 2 intra-operative adverse events, 456 cases without postoperative grade B and grade C biliary leakage, 513 cases without postoperative grade B and grade C liver failure, 395 cases without severe com-plications within postoperative 90 days, 501 cases did not being re-admission caused by severe com-plications within postoperative 90 days. Of the 530 patients, 54.53%(289/530) of patients achieved postoperative TOLS, while 45.47%(241/530) of patients did not achieve postoperative TOLS. (2) Influencing factors of TOLS. Results of multivariate analysis showed that American Society of Anesthesiologists classification >grade Ⅱ, preoperative jaundice, T staging as T3?T4 stage, N staging as N2 stage, liver resection as right hemi-hepatectomy, and neoadjuvant therapy were independent factors influencing TOLS in patients undergoing radical resection of gallbladder carcinoma ( odds ratio=2.65, 1.87, 5.67, 5.65, 2.55, 3.34, 95% confidence interval as 1.22?5.72, 1.18?2.95, 2.51?12.82, 2.83?11.27, 1.41?4.63, 1.88?5.92, P<0.05). Conclusion:American Society of Anesthesiologists classification >grade Ⅱ, preoperative jaundice, T staging as T3?T4 stage, N staging as N2 stage, liver resection as right hemi-hepatectomy, and neoadjuvant therapy are independent factors influencing TOLS in patients undergoing radical resection of gallbladder carcinoma.

To conduct the association between vitamin B12 and mental health in children and adolescents. Five databases were searched for observational studies in any language reporting on mental health and vitamin B12 levels or intake in children and adolescents from inception to March 18, 2022. Two authors independently extracted data and assessed study quality. Qualitative and quantitative analysis of data were performed. The review was registered in the PROSPERO database (CRD42022345476). Fifty six studies containing 37,932 participants were identified in the review. Vitamin B12 levels were lower in participants with autism spectrum disorders (ASD) (standardized mean difference [SMD], −1.61;95% confidence interval [95% CI], −2.44 to −0.79; p ＜ 0.001), attention deficit hyperactivity disorders (SMD, −0.39; 95% CI, −0.78 to −0.00; p = 0.049) compared with control group. Vitamin B12 intake were lower in participants with ASDs (SMD, −0.86; 95% CI, −1.48 to −0.24; p = 0.006) compared with control group, but showed no difference between depression group (SMD, −0.06; 95% CI, −0.15 to 0.03; p = 0.17) and the control group. Higher vitamin B12 intake were associated with lower risk of depression (odds ratio [OR], 0.79; 95% CI, 0.63−0.98; p = 0.034) and behavioral problems (OR, 0.83; 95% CI, 0.69−0.99; p = 0.04). The vast majority of included studies supported potential positive influence of vitamin B12 on mental health, and vitamin B12 deficiency may be a reversible cause for some mental health disorders in children and adolescents.

Objective:To explore the phenotype and mechanism of ferroptosis in steatosis liver ischemia reperfusion injury (IRI) and elucidate the mechanism of targeted inhibition of ferroptosis down-regulating steatosis liver IRI.Methods:First, 20 mice are divided into 2 group according to the different feeding mode: Normal chow diet(NCD group, n=10)and high fat diet(HFD group, n=10). The fatty liver constructs are successful as verified by laboratory tests for relevant indicators and oil red staining.NCD and HFD mice were randomized into two groups sham and IRI.The expression of glutathione peroxidase 4(Gpx4)in liver tissues of each group is detected by Western blot.Morphological phenotypes of mitochondria in liver tissue are observed by transmission electron microscope.Accordingly, it was determined whether ferroptosis occurred in mouse liver IRIs.NCD(n=30)and HFD(n=30)are further randomized into 3 groups: sham(n=10), IRI(n=10)and inhibitor(IRI-fer-1 group, n=10). The serum contents of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)are detected by ALT/AST kits.Hematoxylin-eosin(HE)stain is employed for detecting the degree of liver injury; immunohistochemistry(IHC)and enzyme-linked immunosorbent assay(ELISA)for detecting the levels of inflammatory factors and inflammatory cell infiltration.Similarly, primary hepatocytes from NCD/HFD mice are extracted and the occurrence of ferroptosis is verified by detecting C11-BODIPY(581/591)by fluorescent stain after hypoxia-reoxygenation(H/R).Results:As compared with NCD-IRI group, Gpx4 protein expression declined obviously in HFD-IRI group while serum ALT/AST level spiked markedly( P<0.01). IHC staining of 4-HNE is positive, mitochondrial specific damage is more pronounced and inflammatory infiltration became enhanced.As compared with IRI group, serum level of ALT/AST dropped obviously and infiltration of inflammatory cells and secretion of inflammatory factors are blunted markedly in IRI-fer-1 group( P<0.01). Conclusions:A high degree of ferroptosis and severe inflammatory response during fatty liver IR are features of distinguishing steatosis liver IRI from ordinary liver IRI.Targeted inhibition of ferroptosis lowers inflammation and damage during IR in steatosis liver.
