ObjectiveTo study the effect of the herb pair Mori Folium-Ginseng Radix et Rhizoma （HMG） on glucose and lipid metabolism in the mouse model of type 2 diabetes mellitus and decipher the possible treatment mechanism. MethodsThe db/db mice were chosen as the mouse model of type 2 diabetes mellitus and then treated with HMG at low and high doses （1.56， 3.12 g∙kg^-1， respectively） or metformin （0.26 g∙kg^-1） by gavage for 6 weeks. The normal group and the model group were treated with double distilled water at the same time according to body weight. The 8-h fasting blood glucose and body weight were measured once a week. The oral glucose tolerance test （OGTT） was conducted at the 6th week of dosing. The mice were sacrificed after the end of dosing. Serum levels of lipids ［total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL）， and low-density lipoprotein cholesterol （LDL）］， liver function indicators ［aspartate aminotransferase （AST） and alanine aminotransferase （ALT）］， non-esterified fatty acids （NEFA）， glycosylated serum protein （GSP）， serum glucose （GLU）， fasting insulin （FINS）， and renal function indicators ［creatinine （Crea） and blood urea nitrogen （BUN）］ were measured by enzyme-linked immunosorbent assay. The protein levels of peroxidase proliferator-activating receptor gamma （PPARγ）， acetyl coenzyme A carboxylase （ACC）， and sterol regulatory element-binding protein-1 （SREBP-1） were determined by Western blot. The pathological changes in the liver and pancreas were examined. ResultsCompared with the normal group， the model group presented increased body weight， elevated levels of blood glucose， TG， TC， AST， ALT， GLU， NEFA， GSP， and HDL-C， up-regulated protein levels of ACC and SREBP-1， and down-regulated protein level of PPARγ （P<0.01）. Meanwhile， the model group presented a large amount of lipid droplets and steatosis in the liver， as well as karyopyknosis and lymphocyte infiltration in the pancreas. Compared with the model group， the high- and low-dose HMG groups showed decreased body weight， declined levels of blood glucose， TG， TC， AST， ALT， GLU， NEFA， and GSP， and elevate level of HDL-C （P<0.05， P<0.01）. Moreover， the two groups showcased reduced lipid droplets and steatosis in the liver， as well as enlarged islets with clear boundaries and alleviated lymphocyte infiltration and karyopyknosis. Western blot results showed that the high-dose herb pair group demonstrated down-regulated protein levels of ACC and SREBP-1 and up-regulated protein level of PPARγ （P<0.01）. ConclusionThe HMG can effectively improve the glucose and lipid metabolism in db/db mice by regulating the expression of PPARγ， SREBP-1， and ACC.

Objective: To explore the association between mental health and muscle strength among Chinese adolescents aged 13- 18, providing a theoretical foundation and intervention strategies for mental health promotion. Methods: Data were obtained from the 2019 Chinese National Survey on Students Constitution and Health, including 98 631 Chinese adolescents aged 13- 18. Psychological distress was assessed by using the Kessler Psychological Distress Scale (K10), and mental well being was measured with the Warwick-Edinburgh Mental Well being Scale (WEMWBS). Based on the gender and age specific Z scores of various test items [grip strength, standing long jump, pull ups (for males), and sit ups (for females)], muscle strength index (MSI) was constructed to evaluate the comprehensive level of muscle strength in adolescents. According to the Dual factor Model (DFM) of mental health, participants were categorized into four groups:troubled, symptomatic but content, vulnerable, and complete mental health. Gender differences were analyzed by using Chi-square tests, trends were tested with Cochran-Armitage tests, and multinomial Logistic regression models were applied to assess associations between muscle strength and mental health among adolescents. Results: In 2019, 37.4% of Chinese adolescents aged 13-18 were reported of high mental distress, and 59.9% were reported of low mental well being. Boys had significantly lower rates of high mental distress (35.3%) and low mental well being (55.6%) compared to girls (39.4%, 64.3%), and the differences were of statistical significance ( χ 2=176.13, 780.42, both P <0.05). In 2019, the rate of complete mental health among adolescents showed a downward trend with increasing age ( χ 2 trend = 258.47) and a gradual upward trend with increasing muscle strength levels ( χ 2 trend =123.14)，and both boys and girls exhibited similar trends ( χ 2 trend =103.83, 168.46; 57.00 , 67.34) (all P <0.05). The results of the unordered multiclass Logistic regression model showed that after controlling for confounding factors such as age and gender, when the completely pathological group as a reference, for every 1 unit increase in MSI in adolescents, the likelihood of being in a completely mental health state increased by 29% ( OR = 1.29); for every unit increase in the Z-score for pull ups, the likelihood of being in a completely mental health state increased by 6% ( OR =1.06) among boys; for every 1 unit increase in sit up Z score, the likelihood of being in a completely mental health state increased by 19% ( OR =1.19) among girls (all P <0.05). Conclusions The mental health status of Chinese adolescents is not good enough. Muscle strength is positively associated with mental health.

ObjectiveTo evaluate the effects of Wuhua herbal tea on chronic unpredictable mild stress (CUMS)-induced depression and explore its mechanism of action in combating depression.MethodsWe tested the antidepressant effects of Wuhua herbal tea in a rat model of CUMS-induced depression using fluoxetine as a positive control. The rats were divided into four groups: control group, model group, fluoxetine group, and Wuhua herbal tea group. The rats underwent body weight measurements, sucrose preference test, and open-field test. Enzyme-linked immunosorbent assay kits were used to detect the serum levels of serotonin, dopamine, adrenocorticotropic hormone (ACTH), corticosterone, norepinephrine, and interleukin-6. Intergroup comparisons and detection of brain-derived neurotrophic factor (BDNF), cAMP-response element binding protein (CREB), Janus kinase 2 (JAK2), and signal transducer and activator of transcription 3 (STAT3) mRNA expression in the hippocampus were performed using RT-PCR. Immunohistochemistry was used to identify the expression of phosphorylated JAK2 (p-JAK2) and phosphorylated STAT3 (p-STAT3) proteins in hippocampal paraffin sections of CUMS rats.ResultsCompared with the control group, the model group rats had depressive tendencies, exhibiting low vitality and interest in various behavioral indicators which were signs of despair. The Wuhua herbal tea group statistically increased the levels of serotonin and dopamine in the serum of CUMS rats to varying degrees (P = .015 and P = .002); reduced serum levels of ACTH, corticosterone, norepinephrine, and interleukin-6 (all P .05); and decreased mRNA expression of BDNF, CREB, JAK2, and STAT3 in the hippocampus (all P .05); and decreased p-STAT3 protein levels (P = .006).ConclusionWuhua herbal tea shows antidepressant potential in CUMS rats by modulating the HPA axis and inhibiting JAK2-STAT3 overactivation, alleviating neuroinflammation. It also restores BDNF-CREB pathway function, reducing depressive symptoms.

The transgender children and adolescents(TCAs)face serious social dilemmas in the process of gender identity and expression,which hinders this group from seeking reasonable and equal rights to survival and development.From the perspective of equal rights and the theoretical framework of social dilemma,by interviewing TCAs who seek help from medical social workers in a hospital's multi-disciplinary transgender clinic,this paper revealed that under the traditional system of"binary gender",TCAs lacked social inclusiveness and infrastructure,which led to the two major social dilemmas of"social traps"and"social barriers"encountered by this group in the process of gender expression and gender identity.Specifically,the social gender selection of TCAs often leads to collective irrational reactions and gender punishment,preventing their legal and effective medical services.To this end,the research team used critical methodology to construct a joint disciplinary diagnosis and treatment path for TCAs with the participation of medical social workers,as well as verified that the path has significant intervention effects in rationalizing the needs of TCAs and their families,alleviating their psychological pressure and social adaptation problems in the process of gender identity,fostering a diverse dialogue environment in their families,as well as enhancing their self-efficacy and social participation,to provide assistahce to the TCAs groups in social difficulties,assisting their rights and interests be included in the child-friendly indicator system,and improving the whole society's tolerance and understanding for TCAs group.

Objectives:To evaluate the tricuspid valve(TV)geometric remodeling in patients with idiopathic pulmonary arterial hypertension(IPAH)by three-dimensional transthoracic echocardiography. Methods:Two-dimensional and three-dimensional transthoracic echocardiography were performed in 30 IPAH patients and 15 healthy controls,and the geometry parameters of TV were obtained by four-dimensional auto tricuspid valve quantitative(4D Auto-TVQ)in the right ventricular-focused apical view.Pulmonary arterial hypertension was determined by right heart catheterization within 48 hours of echocardiography. Results:The 4-chamber diameter,tricuspid annular(TA)perimeter,TA area,maximal tenting height,coaptation point height and tenting volume were larger in IPAH patients than those in healthy controls(all P＜0.05),2-chamber diameter was similar between two groups.In IPAH group,maximal tenting height and coaptation point height were moderately correlated with right ventricular end-diastolic volume(r=0.710,r=0.515,both P＜0.05),while TA perimeter,4-chamber diameter and TA area were moderately correlated with right atrial end-systolic volume(r=0.712,r=0.558,r=0.545,all P＜0.05). Conclusions:IPAH patients have larger maximal tenting height,coaptation point height and tenting volume,TA enlargement is mainly visible in 4-chamber diameter.TV tenting height is associated with right ventricular volume,but TA size is associated with right atrial volume in IPAH patients.

Objective:To investigate the application effect of discharge preparation service based on theory of goal attainment on patients with cervical spinal cord injury.Methods:A retrospective cohort study was conducted to analyze the clinic data of 60 patients with cervical spinal cord injury admitted to Zhengzhou Orthopedics Hospital from January 2017 to December 2022, including 49 males and 11 females, aged 23-79 years [(52.2±13.5)years]. Patients were all treated with cervical decompression fusion and internal fixation. Patients admitted from January 2017 to December 2019 were treated with conventional nursing intervention (conventional nursing group, n=30) and patients admitted from January 2020 to December 2022 were treated with discharge preparation service based on theory of goal attainment (discharge preparation service group, n=30). The readiness for hospital discharge of the two groups was compared using the Chinese version of Readiness for Hospital Discharge Scale (RHDS) at 4 hours before discharge. The degree of cervical spinal cord dysfunction of the two groups were compared using Japanese Orthopedic Association (JOA) score before intervention, at discharge and at 6 months after discharge. The complication and unplanned readmission rates of the two groups were compared at 6 months after discharge. Results:All the patients were followed up for 6 months. At 4 hours before discharge, the scores of the three parameters of RHDS containing personal status, adaptability and anticipatory support and the total score of the discharge preparation service group were (20.9±3.5)points, (35.9±2.2)points, (30.4±3.0)points and (87.1±7.8)points respectively, higher than those of the conventional nursing group [(16.2±1.7)points, (32.5±2.2)points, (26.3±2.1)points and (75.0±5.6)points respectively] ( P<0.01). There was no statistically significant difference in the JOA score of the two groups before intervention ( P>0.05). The JOA scores of the discharge preparation service group at discharge and at 6 months after discharge were (11.8±1.7)points and (13.8±1.5)points respectively, higher than those of the conventional nursing group [(10.3±1.8)points and (11.6±1.9)points respectively] ( P<0.01). At 6 months after discharge, the complication rate of the discharge preparation service group was 6.7% (2/30), lower than that of the conventional nursing group [36.7% (11/30)] ( P<0.05). The unplanned readmission rate of the discharge preparation service group was 3.3% (1/30), lower than that of the conventional nursing group [23.3% (7/30)] ( P<0.05). Conclusion:For patients with cervical spinal cord injury, discharge preparation service based on theory of goal attainment can improve the discharge readiness, promote spinal functional recovery and reduce the complication and unplanned readmission rates.
