Objective: To investigate the psychological effect of physical function dependence on maintenance hemodialysis (MHD) patients and their primary family caregivers. Methods: The study was a cross-sectional survey. The MHD patients in the hemodialysis centre, the Third Affiliated Hospital of Guangzhou Medical University from March 2022 to June 2022 were enrolled. The patients' demographics and laboratory data were collected. Katz and Lawton-Brody questionnaires were used to assess patients' physical function, and Five Item Mental Health Inventory (MHI-5) was used to evaluate the psychological conditions of the patients and their primary family caregivers. Multiple linear regression analysis was used to analyze the influencing factors of MHI-5 scores of the patients and their primary family caregivers. Results: A total of 116 patients were included, with 61 males and 55 females. There were 47 patients (40.5%) with physical function dependence. In the physical function dependence group, serum albumin (t=-2.512, P=0.013), MHI-5 scores of patients and their primary family caregivers (t=-8.461, P < 0.001; t=-8.533, P < 0.001) and male ratio (χ2=8.467, P=0.002) were significantly lower, and the age (t=9.754, P < 0.001) and the proportions of hypertension (χ2=20.421, P < 0.001), diabetes (χ2=10.470, P=0.002), cardiovascular and cerebrovascular diseases (χ2=9.898, P=0.003) were significantly higher than those in the normal physical function group. The incidence of mental disorders in MHD patients was 39.7%(46/116), and the incidence of mental disorders in the physical function dependence group was significantly higher than that in the normal physical function group [72.3%(34/47) vs. 17.4%(12/69), χ2=35.275, P < 0.001]. The incidence of mental disorders in the primary family caregivers was 32.8%(38/116), and the incidence of mental disorders in the primary family caregivers of physical function dependence group was significantly higher than that in the normal physical function group [66.0%(31/47) vs. 10.1%(7/69), χ2=39.536, P < 0.001]. The incidence of mental disorders in the primary family caregivers of MHD patients who were not spouses was significantly higher than that of spouses [46.0%(29/63) vs. 17.0%(9/53), χ2=11.028, P=0.001], and in physical function dependence group, the incidence of mental disorders in non-spouses was significantly higher than that in spouses [80.6%(25/31) vs. 37.5%(6/16), χ2=8.749, P=0.003]. Multiple linear analysis showed that bathing (β=-5.182, P=0.015), doing laundry (β=-7.053, P < 0.001), taking medication (β=-8.680, P=0.003), and female patients (β=-2.982, P=0.030) were the influencing factors of MHI-5 scores decline in MHD patients. Bathing (β=-4.404, P=0.032), preparing meals (β=-3.954, P=0.041), managing money (β=-5.067, P=0.021), and female patients (β=-2.466, P=0.042) were the influencing factors of MHI-5 scores decline in primary family caregivers. Conclusions: The incidence of physical function dependence in MHD patients is high, and its manifestations and influencing factors are diverse. The incidence of mental disorders in MHD patients and their primary family caregivers is also high, especially in patients with physical function dependence and non- spouse family caregivers. Clinicians should pay attention to and assess the physical function dependence of MHD patients as early as possible, and intervene in time. At the same time, they should also pay attention to the mental health of MHD patients and their primary family caregivers.

Correlation analysis of mandarin fish (Siniperca chuatsi) growth hormone gene polymorphisms and growth traits

Screening of trait-associated molecular markers can be used to enhance the efficiency of selective breeding. Previously, we produced the first high-density genetic linkage map for the mandarin fish (Siniperca chuatsi) and identified 11 quantitative-trait loci significantly associated with growth, of which one is located within the growth hormone (GH) gene. To investigate the GH gene polymorphisms and their correlation with growth, the complete sequence was cloned and 32 single-nucleotide polymorphisms (SNPs) and one simple-sequence repeat (SSR)were identified. Of which, eight SNPs (G1–G8) and the SSR (GH-AG)were selected for genotyping and correlation analysis with growth traits in a random population. The results showed that the four novel polymorphicloci (G1, G2, G3 and GH-AG) were significantly correlated with growth traits of mandarin fish (P < 0.05). Of these, G1, G3 and GH-AG showed highly significant correlations with multiple growth traits (P < 0.01) and the combined SNP analysis showed that G1–G3 formed four effective diplotypes (D1–D4), among which D1 was highly significantly greater than D4 (P < 0.01) for some important growth traits. In conclusion, our results show that the four polymorphic loci G1–G3 and GH-AG within the mandarin fish GH gene are significantly correlated with growth traits and could be used as candidate molecular markers for selective breedingof superior varieties of mandarin fish.

Objective To establish a method to identify unknown samples based on combined use of gas chromatography-mass spectrometry （GC-MS）, high resolution mass spectrometry （HRMS） and nuclear magnetic resonance spectrum （NMR） technique. Methods The unknown samples were dissolved in methanol solution containing internal standard SKF525A and detected by GC-MS and HRMS. The mixed samples were separated and purified by silica gel column chromatography, and then dissolved in methanol-d4 solution for structural analysis of 1H nuclear magnetic resonance spectroscopy （1H NMR）. Results The characteristic fragment ions （m/z） were 86.1 （base peak）, 71.2, 121.1, and 149.0, and the accurate mass number of molecular ion peak was measured by HRMS to be 236.128 89. By combined use of data analysis and database comparison, a new psychoactive substance of the cathinone class, Dibutylone, was detected in the sample, and the sample also contained a small amount of caffeine. The sample was purified, then identified using 1H NMR, and was further confirmed to be Dibutylone. In addition, the GC-MS retention time and characteristic fragment ions of the main components of the sample were consistent with those of Dibutylone reference material. Conclusion The method established in this study can be used for the identification of Dibutylone in mixed samples.

Advances in NMDA receptors-related antidepressants / 中国药理学通报

Recent studies have demonstrated that ketamine , an N-methyl-D-aspartate ( NMDA ) receptor antagonist , can pro-duce rapid and effective antidepressant actions , especially for patients with treatment-resistant depression , bipolar disorder and suicide idea.However, the clinical application of ketamine is limited by its psychotomimetic adverse reactions and potential a-buse.Therefore, development of novel ketamine-like antidepres-sant agents with fewer side effects is actively investigated currently.The latest researches indicate that the metabolites of ket-amine, the S-ketamine/R-ketamine and the modulators of NM-DA receptor subunits can exert safe and effective antidepressant actions.In this article, the research advance in NMDA recep-tors-related antidepressants mentioned above will be reviewed .

Acute Fornix Deep Brain Stimulation Improves Hippocampal Glucose Metabolism in Aged Mice / 中华医学杂志(英文版)

<p><b>Background</b>A beneficial memory effect of acute fornix deep brain stimulation (DBS) has been reported in clinical studies. The aim of this study was to investigate the acute changes in glucose metabolism induced by fornix DBS.</p><p><b>Methods</b>First, the Morris water maze test and novel object recognition memory test were used to confirm declined memory in aged mice (C57BL/6, 20-22 months old). Then, four groups of mice were used as follows: aged mice with stimulation (n = 12), aged mice with sham-stimulation (n = 8), adult mice (3-4 months old) with stimulation (n = 12), and adult mice with sham-stimulation (n = 8). Ipsilateral hippocampal glucose metabolism and glutamate levels were measured in vivo by microdialysis before, during, and after fornix DBS treatment. Histological staining was used to verify the localization of electrodes and mice with inaccurate placement were excluded from subsequent analyses. The effects of fornix DBS on extracellular glucose, lactate, pyruvate, and glutamate levels over time were analyzed by repeated-measures analysis of variance followed by Fisher's least significant difference post hoc test.</p><p><b>Results</b>The aged mice had a higher basal lactate/pyruvate ratio (LPR) and lactate/glucose ratio (LGR) than the adult mice (LPR: 0.34 ± 0.04 vs. 0.13 ± 0.02, t = 4.626, P < 0.0001; LGR: 6.06 ± 0.59 vs. 4.14 ± 0.36, t = 2.823, P < 0.01). Fornix DBS decreased the ipsilateral hippocampal pyruvate and lactate levels (P < 0.05), but the glucose levels were not obviously changed in aged mice. Similarly, the LGR and LPR also decreased in aged mice after fornix DBS treatment (P < 0.05). Glucose metabolism in adult mice was not significantly influenced by fornix DBS. In addition, fornix DBS significantly decreased the ipsilateral hippocampal extracellular levels of glutamate in aged mice (P < 0.05), while significant alterations were not found in the adult mice.</p><p><b>Conclusions</b>The present study provides experimental evidence that fornix DBS could significantly improve hippocampal glucose metabolism in aged mice by promoting cellular aerobic respiration activity.</p>

Predictor Analysis in Patients of Paroxysmal Atrial Fibrillation Recurrence After Radiofrequency Ablation / 中国循环杂志

Objective: To explore the predictors in patients of paroxysmal atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA). Methods: A total of 142 PAF patients received RFCA in our hospital from 2013-03 to 2016-03 were studied. The patients were divided into 2 groups: Recurrence group, n=46 and Non-recurrence group, n=96. Clinical data was compared between 2 groups and AF recurrent predictors were studied by single and multivariate Logistic regression analysis. Based on quartiles of uric acid (UA) level, the patients were categorized in another set of 4 groups: Q1 group, UA<259 μmol/L, n=33, Q2 group, UA 259-320 μmol/L, n=37, Q3 group, UA 321-380 μmol/L, n=37 and Q4 group, UA>380 μmol/L, n=35. The influence of UA on AF recurrence was measured by Kaplan-Meier test, the predictive value of UA combining metabolic syndrome (UA+MS) on AF recurrence was studied by ROC curve analysis. Results: The BMI, diabetes, MS, AF duration, CHADS2 score, creatinine, UA and BNP were different between Recurrence group and Non-recurrence group, all P<0.05. Logistic regression analysis indicated that AF duration (OR=1.02,95% CI 1.01-1.03, P=0.002), UA level (OR=1.01, 95% CI 1.00-1.01, P=0.046) and MS (OR=4.73, 95% CI 1.36-16.45, P=0.014) were the independent predictors for AF recurrence. UA quartile analysis indicated that gender, BMI, MS, creatinine, LVEF and the incidence of AF recurrence had signifcant discrepancy by different UA levels, all P<0.05. ROC curve showed that the predictive values for UA+MS in AF recurrence had the sensitivity at 80.4%, specificity at 74.1% (AUC 0.79±0.04, 95% CI 0.71-0.89, P=0.0001), for UA in AF recurrence had the sensitivity at 73.9%, specificity at 57.2% (AUC 0.66, 95% CI 0.56-0.76, P=0.02); UA+MS had the higher predictive value than UA alone, P<0.05. Conclusion: Both UA and MS were related to AF recurrence, high UA level combining MS had certain predictive value for AF recurrence in PAF patients after RFCA.
