ABSTRACT

Objective@#To explore the pre-exposure prophylaxis (PrEP) awareness, willingness, uptake patterns, barriers and needs among Chinese student men who have sex with men (MSM), so as to provide relevant evidence for targeted interventions with PrEP.@*Methods@#A proportional sampling method was used to conduct a cross sectional survey of MSM aged 16 years and older residing in 21 provinces, municipalities, and autonomous regions in mainland China between October 20 and December 20, 2021, to collect information on demographic and sexual behavioral characteristics, and 923 students of them were selected as the subjects of this study. The chi-square test and Fisher s test were used for univariate analysis, followed by multivariate Logistic regression to analyze the influencing factors of PrEP awareness and uptake.@*Results@#According to the cascade analysis method, the awareness, willingness, uptake and adherence rates of PrEP among the student MSM were obtained as 88.95%, 67.36%, 13.20% and 45.21 %, respectively. HIV testing more than once in the last 3 months, and all of them were aware of the HIV test results of their sexual partners, and those with high frequency of condom use had a higher rate of awareness ( OR =2.32, 1.79, 1.69, P <0.05). Willingness rates were higher for those from the pilot city, using substances, and HIV testing more than once in the last 3 months ( OR =2.13, 1.65, 1.69, P <0.05). Higher rates of uptake were found among those from high risk and pilot areas, presence of commercial sex, substance use, and high literacy ( OR =5.60, 3.54,2.81, 1.92, 4.54, P <0.05). Adherence rates were higher among those who used one pill per day or both ( OR =12.77, 13.26, P <0.05). The barriers and needs faced by student MSM were primarily personal concerns about medication side effects, preventative effects, and confidence in sexual behavioral styles, and the high cost of medication and related service costs.@*Conclusions@#The student MSM population in China is characterized by high awareness, low willingness, low uptake, and low adherence to PrEP. Targeted interventions should be considered and tailored by the departments to facilitate PrEP promotion among student MSM.

ABSTRACT

ObjectiveMolecular docking and animal experiments were employed to explore the protective effect and mechanism of Da Chengqitang (DCQD) on intestinal barrier in septic mice. MethodText mining method was used to screen the active ingredients in DCQD. AutoDock Tools and Discovery Studio were used to study the interactions of active components with the core target proteins [claudin-1, tumor necrosis factor (TNF)-α, interleukin (IL)-6, endogenous antimicrobial peptide mCRAMP, Toll-like receptor 4 (TLR4), and myeloid differentiation primary response gene 88 (MyD88)] in sepsis. Fifty C57BL/6 mice were randomized into sham, model, low- and high-dose (4 g∙kg-1 and 8 g∙kg-1) DCQD, and ulinastatin groups (n=10). Before, during, and after the day of modeling surgery, each group was administrated with corresponding drugs. The mice in other groups except the model group were subjected to modeling by cecal ligation and puncture. Enzyme-linked immunosorbent assay (ELISA) was used measure the serum level of D-lactic acid to assess intestinal mucosa permeability. Hematoxylin-eosin staining was employed to observe the histopathological changes in the ileum and assess the intestinal mucosal damage and inflammatory infiltration. Western blotting was employed to determine the expression levels of tight junction proteins claudin-1 and occludin in the ileal tissue, which were indicative of the bowel barrier function. The TNF-α and IL-6 levels were measured by ELISA to assess the intestinal inflammation. The expression of mCRAMP in the ileal tissue was observed by immunohistochemistry. The mRNA levels of mCRAMP, TLR4, and MyD88 in mouse ileal tissue were determined by Real-time polymerase chain reaction, on the basis of which the mechanism of DCQD in protecting the intestinal barrier of septic mice was explored. ResultMolecular docking results showed that most of the 10 active ingredients of DCQD that were screened out by text mining could bind to sepsis targets by van der Waals force, hydrogen bonding, and other conjugated systems. The results of animal experiments showed that compared with the model group, low- or high-dose DCQD lowered the D-lactic acid level in the serum (P<0.01), alleviated damage to the ileal tissue and mucosal edema, protected the small intestine villus integrity, reduced inflammatory cell infiltration, promoted the expression of claudin-1 (P<0.01), lowered the IL-6 level (P<0.01), up-regulated the mRNA and protein levels of mCRAMP (P<0.01), and down-regulated the mRNA and protein levels of TLR4 and MyD88 (P<0.01) in the ileal tissue. In addition, high-dose DCQD lowered the TNF-α level and promoted the expression of occludin in the ileum tissue (P<0.01), and low-dose DCQD up-regulated the protein level of occludin in the ileum tissue (P<0.05). ConclusionDCQD has a protective effect on intestinal barrier in septic mice. It can reduce intestinal inflammation, repair intestinal mucosal damage, improve the tight junction protein level, and reduce intestinal mucosal permeability by up-regulating the mRNA and protein levels of mCRAMP and the down-regulating the expression of genes in the TLR4/MyD88 pathway.

ABSTRACT

ObjectiveTo explore the mechanism of modified Liuwei Dihuangtang in preventing and treating renal injury in diabetic kidney disease (DKD) via the angiotensin-converting enzyme 1 (ACE1)/angiotensin Ⅱ (AngⅡ)/angiotensin Ⅱ type 1 receptor (AT1R) axis. MethodFifty male SD rats were randomized into a normal group (n=8) and a modeling group (n=42). The rats in the modeling group were fed with a high-sugar and high-fat diet for 6 weeks and intraperitoneally injected with 35 mg·kg-1 streptozotocin (STZ) to establish the model of DKD. After successful modeling, the rats were randomized into model, traditional Chinese medicine (modified Liuwei Dihuangtang granules 21 g·kg-1), western medicine (losartan potassium, 33 mg·kg-1), and integrated Chinese and western medicine (losartan potassium 33 mg·kg-1 combined with modified Liuwei Dihuangtang granules 21 g·kg-1) groups. The levels of fasting blood glucose (FBG), urinary protein (Up), blood urea nitrogen (Bun), and serum creatinine (SCr) were measured in each group after 8 consecutive weeks of drug intervention. Enzyme-linked immunosorbent assay was employed to determine the serum levels of ACE1, AngⅡ, and AT1R. Western blot was employed to measure the protein levels of ACE1, AngⅡ, and AT1R in the renal tissue. The pathological and morphological changes of the renal tissue were observed after hematoxylin-eosin (HE) staining, Masson staining, and periodic acid Schiff 's (PAS) staining. The fecal samples of rats in each group were collected for 16S rDNA high-throughput sequencing. ResultCompared with the normal group, the model group showed elevated levels of Up, FBG, Bun, SCr, ACE1, AngⅡ, and AT1R (P<0.01), serious lesions in the renal tissue, up-regulated protein levels of ACE1, AngⅡ, and AT1R (P<0.01), increased Firmicutes/Bacteroidetes (F/B) ratio, decreased relative abundance of Lactobacillus, and increased relative abundance of Moralella and Bifidobacteria. Compared with the model group, drug intervention lowered the levels of Bun, SCr, ACE1, AngⅡ, and AT1R (P<0.01) and alleviated the pathological changes in the renal tissue. Chinese medicine and integrated Chinese and western medicine lowered the levels of Up and FBG (P<0.01), and western medicine and integrated Chinese and western medicine down-regulated the protein levels of ACE1, AngⅡ, and AT1R. In addition, Chinese medicine down-regulated the protein levels of AngⅡ (P<0.01) as well as ACE1 and AT1R (P<0.05). Chinese medicine and integrated Chinese and western medicine decreased the F/B ratio, and western medicine and Chinese medicine increased the relative abundance of Blautia. Chinese medicine and integrated Chinese and western medicine increased the relative abundance of Lactobacillus, Ruminococcus undetermined genera, and Bifidobacteria, decreased the relative abundance of Moralella, and increased the Chao 1 and Ace indexes (P<0.05). Compared with the western medicine group, the integrated Chinese and western medicine group showed lowered levels of Up (P<0.01), Bun (P<0.05), and ACE1 and AT1R (P<0.01), down-regulated protein levels of ACE1, AngⅡ, and AT1R (P<0.05), alleviated pathological changes in the renal tissue, increased relative abundance of Bifidobacteria, and increased Chao 1 and Ace indexes (P<0.05). ConclusionModified Liuwei Dihuangtang combined with losartan potassium can mitigate renal fibrosis by regulating the ACE1/AngⅡ/AT1R axis, increasing the relative abundance of Lactobacillus and Bifidobacterium, reducing the relative abundance of Moralella, improving the richness and evenness of intestinal flora, and alleviating pathological damage in the renal tissue.

ABSTRACT

Tripterygium wilfordii is widely used in the treatment of immune system disease and has a remarkable curative effect. Triptolide and Tripterygium glycosides are the most commonly used active ingredients in clinical practice, but their treatment window is narrow and there are many side effects. The damage involves the reproductive system, blood system, cardiovascular system, digestive system, etc. Based on clinical observations and literature summaries, the symptoms of adverse reactions mostly occur in the digestive system (liver and gastrointestinal tract). Relevant scholars have launched a lot of studies of the manifestations of liver injury induced by T. wilfordii and the mechanism of liver injury. The mechanism is mainly related to liver cell apoptosis, induction of oxidative stress, immune injury, excessive autophagy of liver cells, abnormal fatty acid metabolism, and abnormal enzyme metabolism in liver tissues. This article reviewed and summarized relevant literature on gastrointestinal injury caused by T. wilfordii, but there are few studies on the manifestations and mechanisms of adverse reactions, which still need further research by scholars. In addition, this article also summarized the research on how to reduce toxicity and enhance efficacy of prescriptions prepared from T. wilfordii in the digestive system, mainly involving compatibility with western medicines (Methotrexate, Leflunomide, Iguratimod, etc.), use along or combination with Chinese medicines (single Chinese medicine, Chinese medicine monomers, and Chinese medicine compounds), acupuncture and moxibustion (electroacupuncture and moxibustion), dosage form improvement (glycol plastid gel, self-dissolving microneedle, solid lipid nanoparticles, gastric floating sustained-release capsules, etc.), processing (steaming, stir-frying, radish seed processing, money grass processing, licorice processing, etc.), and other methods to reduce toxicity. To sum up, this article analyzed the manifestations, mechanisms, and methods of reducing toxicity and enhancing efficacy of T. wilfordii-induced liver injury and gastrointestinal injury by sorting out relevant literature, in order to provide a reference for the clinical application of T. wilfordii and some research ideas for the future in-depth study of T. wilfordii-induced digestive system injury.

ABSTRACT

Sleep deprivation (SD) has a profound impact on the central nervous system, resulting in an array of mood disorders, including depression and anxiety. Despite this, the dynamic alterations in neuronal activity during sleep deprivation have not been extensively investigated. While some researchers propose that sleep deprivation diminishes neuronal activity, thereby leading to depression. Others argue that short-term sleep deprivation enhances neuronal activity and dendritic spine density, potentially yielding antidepressant effects. In this study, a two-photon microscope was utilized to examine the calcium transients of anterior cingulate cortex (ACC) neurons in awake SD mice in vivo at 24-hour intervals. It was observed that SD reduced the frequency and amplitude of Ca2+ transients while increasing the proportions of inactive neurons. Following the cessation of sleep deprivation, neuronal calcium transients demonstrated a gradual recovery. Moreover, whole-cell patch-clamp recordings revealed a significant decrease in the frequency of spontaneous excitatory post-synaptic current (sEPSC) after SD. The investigation also assessed several oxidative stress parameters, finding that sleep deprivation substantially elevated the level of malondialdehyde (MDA), while simultaneously decreasing the expression of Nuclear Factor erythroid 2-Related Factor 2 (Nrf2) and activities of Superoxide dismutase (SOD) in the ACC. Importantly, the administration of gallic acid (GA) notably mitigated the decline of calcium transients in ACC neurons. GA was also shown to alleviate oxidative stress in the brain and improve cognitive impairment caused by sleep deprivation. These findings indicate that the calcium transients of ACC neurons experience a continuous decline during sleep deprivation, a process that is reversible. GA may serve as a potential candidate agent for the prevention and treatment of cognitive impairment induced by sleep deprivation.

ABSTRACT

OBJECTIVE To study the protective effects of Dachengqi decoction (DCQD) on intestinal septic mice, and to explore the possible mechanisms from the Toll-like receptor 4(TLR4)/myeloid differentiation factor 88(MyD88) signaling pathway. METHODS The SPF male C57BL/6J mice were randomly divided into Sham group, Sham+DCQD-H group, model (CLP) group, DCQD-L group, DCQD-H group and Positive group. The model of intestinal sepsis was established by cecal ligation and puncture in CLP group, DCQD-L group, DCQD-H group and Positive group. Three days before the operation and seven days after the operation, DCQD-L group and DCQD-H group were given DCQD intragastrically at 4, 8 g/kg (calculated by crude drug), respectively. Positive group was given ulinastatin intraperitoneally 2 h before operation and 7 d after the operation (at 50 000 U/kg). In Sham group and Sham+DCQD-H group, only cecum of mice was exposed without ligation and puncture. Sham+DCQD- H group was given DCQD intragastrically (8 g/kg,calculated by crude drug) 3 days before the operation and 7 days after the operation. Both the Sham group and CLP group were given normal saline 0.2 mL intragstrically and intraperitoneally each day, for 10 consecutive days. After the operation, the severity of sepsis was assessed, and the 7 d survival rate of mice was assessed. One hour after the last medication, the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in serum and ileum of mice were determined; the pathological and morphological changes of mice’s liver, lung, kidney and ileum were observed; mRNA expressions of the TLR4 and MyD88 in ileum were tested. RESULTS Compared with CLP group, sepsis score, the levels of TNF-α and IL-6 in serum and ileum (except for IL-6 in ileum of DCQD-L group), damage score of the liver, lung, kidney and ileum, mRNA expressions of TLR4 and MyD88 in ileum were all decreased significantly in DCQD-L group and DCQD-H group (P<0.05 or P<0.01), while 7 d survival rate (except for DCQD-L group) was increased significantly (P<0.05). The damage to liver tissue in mice was significantly improved, and inflammation infiltration and apoptosis were reduced; lung tissue damage had been alleviated, with varying degrees of improvement in alveolar atrophy, bleeding and edema; the renal tissue damage was improved and weakened dilation of renal tubular lumen was weakened; the damage and edema of ileal tissue were significantly improved. CONCLUSIONS DCQD may exert a protective role on intestinal septic model mice. The mechanism may be related to the inhibition of systemic inflammation, the reduction of multiple organ damage, and down-regulation of TLR4/MyD88 signaling pathway.

ABSTRACT

Diabetic nephropathy (DN) is a common clinical complication of diabetes, the main cause of end-stage renal disease (ESRD), and a key determinant of survival in diabetic patients. The pathogenesis of DN is complex, and it is currently believed to be associated with hemodynamic abnormalities, intestinal flora disturbances, glucose and lipid metabolism disorders, oxidative stress, genetic susceptibility, and protein non-enzymatic glycosylation. The local renin-angiotensin system (RAS) has always been the core of the pathogenic and progressive changes of DN. Once activated, it will induce the massive release of oxygen free radicals in the blood vessels, damage the endothelial function, and affect the microcirculation of the body. The recent studies demonstrate that intestinal flora and its metabolites may affect the occurrence and development of DN by activating or antagonizing the local RAS. Compared with western medicine treatment, traditional Chinese medicine (TCM) has the advantages of multiple targets and little toxic and side effects. Many TCM scholars have found that single herbs, their active ingredient extracts, and TCM compound prescriptions can improve kidney function by regulating the local RAS or intestinal flora. Specifically, the Chinese medicinal materials tonifying spleen (Codonopsis Radix, Dioscoreae Rhizoma, Atractylodis Macrocephalae Rhizoma, and Poria), replenishing kidney (Rehmanniae Radix Praeparata, Corni Fructus, and Pseudostellariae Radix), and activating blood, resolving stasis, and dredging collaterals (Hirudo, Salviae Miltiorrhizae Radix et Rhizoma, and Angelicae Sinensis Radix) have the regulatory effect. This article summarizes the roles of intestinal flora and local RAS in the occurrence and development of DN, and analyzes the animal experiments or clinical trials of TCM intervention in DN in recent years, aiming to provide more therapies and a theoretical basis for the treatment of DN with integrated TCM and Western medicine.

ABSTRACT

Backgroud Beta-cypermethrin and emamectin benzoate are widely used for the prevention and control of pests in the greenhouse planting industry, and their combined exposure may increase the accumulation of beta-cypermethrin and emamectin benzoate in organisms and affect human health. Objective Based on the changes in reproductive hormone levels in the hypothalamic-pituitary-ovarian (HPO) axis, to investigate the effect of combined exposure to beta-cypermethrin and emamectin benzoate on the estrous cycle of female mice. Methods Twenty-four healthy adult SD rats were randomly divided into a blank control group, a beta-cypermethrin group (Beta-CYP, 53 mg·m−3), an emamectin benzoate group (EMB, 8 mg·m−3), and a beta-cypermethrin and emamectin benzoate combined exposure group (Beta-CYP+EMB, Beta-CYP 53 mg·m−3 + EMB 8 mg·m−3). Six rats in each group were exposed to the designed treatment protocol by aerosol inhalation 6 d a week for 13 weeks. The general condition of the rats was observed in real time during the treatment. From the 12th week of exposure, a 10-day reproductive tract smear was performed on the rats to observe the estrous cycle. The rats were neutralized on the second day after the end of the treatment protocol, and the ovarian tissues were stained with HE to observe histopathological changes. Serum levels of gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) were measured by ELISA. Experimental results were expressed as mean ± standard deviation (\begin{document}$ \overline{x}\pm s $\end{document}). One-way ANOVA was used for comparison among groups, and LSD test for pairwise comparison between groups. The significance level was α=0.05. Results After four weeks of the treatment protocol, the rats in the Beta-CYP group and the Beta-CYP+EMB group continued to be hyperactive and irritable, while the EMB group showed symptoms of mental disorder, decreased activity, and slow response. On the 90th day of the treatment protocol, the body weight of rats in the control group increased to (314.51±2.44) g, and that in the Beta-CYP+EMB group only increased to (253.47±1.50) g. There was no abnormal cellular morphology in the control group; however, small deeply stained nuclei appeared in the Beta-CYP group, the EMB group, and the Beta-CYP+EMB group, and abnormal morphological development of keratinized epithelial cells in the Beta-CYP+EMB group was found. The estrous cycle of rats in the control group was (97.83±4.17) h, and compared with the control group, the estrous cycles of rats in the Beta-CYP group, the EMB group, and the Beta-CYP+EMB group were prolonged to (134.33±7.53) h, (126.50±5.28) h, and (156.00±6.66) h, respectively. The results of ANOVA showed that the numbers of leukocytes (527.17±15.83), keratinized epithelial cells (35.67±4.32), and non-keratinized epithelial cells (70.50±4.51) in the vaginal smears during diestrus in the Beta-CYP+EMB group were significantly lower than those in the control group (752.50±28.89, 50.50±2.74, 101.33±7.92) (P<0.001). The hormone levels of GnRH and FSH in the control group were (5.13±0.59) and (0.76±0.09) IU·L−1 respectively, while the levels in the Beta-CYP+EMB group were increased to (16.86±0.59) and (3.80±0.19) IU·L−1 respectively (P<0.05). The levels of LH and E2 in the control group were (12.93±0.81) IU·L−1 and (22.23±1.44) pmol·L−1 respectively, and the levels in the Beta-CYP+EMB group were decreased to (5.63±0.41) IU·L−1 and (10.45±0.78) pmol·L−1 respectively (P<0.05). Conclusion The combined exposure to beta-cypermethrin and emamectin benzoate may ultimately affect the estrous cycle of female rats by interfering with the secretion of reproductive hormones involved in the HPO axis.

ABSTRACT

Objective:To evaluate a newly designed basket fit for digital cholangioscope in non-radiation endoscopic lithotomy for common bile duct stones.Methods:Seventy-eight patients who underwent non-radiation endoscopic removal of common bile duct stones at Zhongda Hospital Southeast University between February and October 2021 were enrolled in the randomized controlled trial, and were randomly assigned into the new basket group ( n=35) and the conventional basket group ( n=43) by drawing lots. Procedures of cholangioscope-based biliary exploration and stone removal by baskets, volume of water irrigation, time lengths of biliary exploration, stone removal and whole endoscopic procedure, and adverse events were compared. Results:Compared with the conventional basket group, the new basket group needed less biliary explorations (1.08±0.28 VS 2.30±0.51, t=-12.535, P<0.001), smaller volume of water irrigation (46.14±11.89 mL VS 78.62±10.09 mL, t=-13.052, P<0.001), and shorter time of biliary exploration and stone removal (9.69±2.97 min VS 12.67±2.51 min, t=-4.815, P<0.001) and whole endoscopic procedure (30.17±7.19 min VS 33.44±6.69 min, t=-2.076, P=0.041). The incidence of adverse events was not significantly different between the two groups [5.7% (2/35) VS 11.6% (5/43), χ2=0.826, P=0.363]. Conclusion:This newly designed basket can facilitate digital cholangioscope-guided non-radiation endoscopic removal of common bile duct stones with the advantages of shorter operation time, less exploration time of choledochoscopy and smaller volume of water irrigation.

ABSTRACT

Objective:To explore the effects of Onodera′s prognostic nutritional index (PNI) on the prognosis of locally advanced oropharyngeal squamous cell carcinoma (LA-OPSCC) after induction chemotherapy followed by sequential chemoradiotherapy.Methods:A retrospective analysis was conducted on the clinical data of 52 LA-OPSCC patients receiving induction chemotherapy followed by sequential chemoradiotherapy in The Affiliated Cancer Hospital of Guizhou Medical University during 2014-2018. The PNI values of all the patients at different treatment phases were statistically analyzed, and the ROC curve was employed to determine the optimal critical value of PNI. The patients in this study were divided into a well-nourished group ( n = 27) and a poorly-nourished group ( n = 25). The Kaplan-Meier method was used for survival analysis. The Cox proportional hazards model was utilized to analyze the relationships between different nutritional status and prognosis. Clinical features and adverse reactions were compared between the two groups. Results:The PNI values decreased significantly after radiotherapy, with an optimal critical value of 42.4. The 5-year overall survival (OS) and progression-free survival (PFS) of the well-nourished group (PNI ≥ 42.4) were 62.6% and 60.9%, respectively, which were significantly higher than those (30.1% and 29.7%) of the poorly-nourished group (PNI < 42.4, χ2 = 11.12, 5.74, P < 0.05). The multivariate analysis showed that PNI was an independent prognostic factor for the OS after radiotherapy ( HR = 2.752, 95% CI: 1.095-6.917, P = 0.031). The LA-OPSCC patients aged over 60 years or those who did not respond to induction chemotherapy accounted for a higher proportion of malnutrition after chemoradiotherapy ( χ2 = 4.89, 5.05, P < 0.05). Conclusions:PNI after radiotherapy can be used as a prognostic factor in the evaluation of LA-OPSCC patients receiving induction chemotherapy followed by sequential chemoradiotherapy. The LA-OPSCC patients aged over 60 years or those who do not respond to induction chemotherapy should receive more nutritional support during the chemoradiotherapy.

ABSTRACT

Objective:To explore the optimal acceleration factor and feasibility of the compressed SENSE (CS) technique in non-contrast MR coronary angiography (NMRCA) for clinical practice.Methods:The image data of completed coronary CTA and 3.0 T NMRCA sequence in 31 patients with suspected coronary heart disease were prospectively recruited at Fuyang People′s Hospital from August 2021 to November 2021. NMRCA sequences included conventional SENSE2 sequence and CS sequences with acceleration factors of 4, 5, and 6, respectively. The subjective scores of image quality and the objective scores, the contrast ratios between assessed coronaries and myocardium (CMCR) were compared among the 4 groups using the Friedman and Wilcoxon rank sum test.Results:Compared with the conventional SENSE2 [(343±46)s], the scan time of CS4 (269±36), CS5 (214±29) and CS6 (178±26) s were shortened by 21.5%, 37.5% and 48.0%, respectively. There was a good consistency between the subjective scores of the four groups (Kappa=0.769, 95% Cl 0.738-0.800). There was no significant difference in subjective score and CMCR value between CS4 and SENSE2 ( P>0.05). The coronary artery segments of CS5 and CS6 were significantly different from SENSE2 group ( P<0.05). Conclusions:For 3.0 T NMRCA, CS technology shows high feasibility. The CS4 can reduce imaging time while ensuring high-quality coronary arterial images, which has a well-established clinical application value for NMRCA.

ABSTRACT

Objective:To investigate the effects of hydroxysafflor yellow A (HSYA) on depressive-like behavior and expression of type A γ-aminobutyric acid receptor(GABAAR)in hippocampus of chronic restraint stress model mice.Methods:The SPF grade male C57BL/6C mice were divided into Control group, HSYA group, Model group, Model + HSYA group and Model + fluoxetine group according to random number table method, with 12 mice in each group.Mice model of depression was established by chronic restraint stress.Mice in HSYA group and Model+ HSYA group were intraperitoneally injected with HSYA(20 mg/kg), mice in Model+ fluoxetine group were injected intraperitoneally with fluoxetine (10 mg/kg), and mice in Control group and Model group administered with 0.9% sodium chloride solution intraperitoneally once a day for 14 days.Then, the forced swimming test (FST) and tail suspension test (TST) were performed to evaluate the depressive-like behavior of mice, and the protein expression levels of different subtypes of GABAAR in the hippocampus of mice were determined by Western blot.SPSS 19.0 and GraphPad Prism 8.0 software were used for data statistical analysis and mapping.One-way ANOVA was used for comparison among groups, and Tukey-HSD test was used for further pairwise comparison.Results:(1) In the behavioral tests, there were significant differences in swimming immobility time of FST and tail suspension immobility time of TST among the five groups ( F=21.59, 20.81, both P<0.05). The swimming immobility time ((143.91±9.97) s) and tail suspension immobility time (( 107.00±6.54) s) in Model group were higher than those in Control group ((52.92±6.70) s, ( 43.50±5.96) s, both P<0.05). There were no significant difference in swimming immobility time and tail suspension immobility time between Model+ HSYA group ((26.17±7.69)s, ( 20.17±7.89)s) and Model+ fluoxetine group ((61.60±16.22)s, (34.14±10.74)s)(both P>0.05), but the swimming immobility time and tail suspension immobility time in these two groups were lower than those in Model group (both P<0.05). (2) The Western blot results showed that there were significant differences in the expression of GABAARβ1 and GABAARβ2 protein in hippocampus among the four groups ( F=12.21, 11.40, both P<0.05). The expression levels of GABAARβ1(45.60±10.76) and GABAARβ2 (46.27±4.82) protein in hippocampus of Model group were lower than those in Control group ((100.00±3.44), (100.00±3.26), both P<0.05). Compared to Model group, the expression of GABAARβ1 (79.91±5.00) and GABAARβ2 (79.08±5.53) protein in hippocampus of Model+ HSYA group were higher (both P<0.05). In addition, the expression of GABAARα1 and GABAARγ1 proteins in hippocampus were not significantly different among the four groups( F=0.23, 0.10, both P>0.05). Conclusion:HSYA can effectively alleviate depressive-like behavior in depression model mice, which may be related with the upregulation of GABAARβ1 and GABAARβ2 of hippocampus tissue.

ABSTRACT

【Objective:】 To understand the current status of narrative nursing knowledge, attitude, and practice (KAP) among nurses in grade A tertiary hospitals, and to provide a basis for the development of narrative nursing in relevant areas. 【Methods:】 Using convenience sampling methods, 931 nurses from three grade A tertiary hospitals in Xi’an were selected as subjects. A cross-sectional survey was conducted using the Clinical Nurses’ Narrative Nursing Knowledge and Trustworthiness Questionnaire and the General Self-Efficacy Scale. Multiple linear regression analysis was used to explore the influencing factors of nurses’ narrative nursing KAP. 【Results:】 The scores on the three dimensions of narrative nursing KAP were (23.70±2.99) points, (31.69±5.92) points, and (30.26±5.32) points, respectively. Nursing workload, general self-efficacy, professional title, and nursing satisfaction were the influencing factors of nurses’ narrative nursing knowledge dimension (P<0.05). There were statistically significant differences in nurses’ narrative nursing attitude dimension among nursing workload, general self-efficacy, professional title, monthly income, and nursing satisfaction (P<0.05). Nursing workload, general self-efficacy, nursing satisfaction, and accompanying experience were the influencing factors of nurses’ narrative nursing behavior dimension (P<0.05). 【Conclusion:】 Nurses in grade A tertiary hospitals have moderate narrative nursing knowledge, positive attitudes, and poor practice execution. The high nursing workload is the main barrier factor for the current development of narrative nursing. Nursing managers should actively build a diversified training system and guarantee system to boost the development of narrative nursing in clinical nursing work, and further promote the development of narrative nursing concepts.

ABSTRACT

Objective@#To analyze the correlation between physical activity and depressive symptoms in adolescents, so as to provide a reference for the early prevention of depression among adolescents.@*Methods@#Using a random cluster sampling method, 8 102 adolescents from Shanghai, Urumqi, Changsha and Kunming were investigated via the Physical Activity Assessment Questionnaire of Chinese Children and Adolescents aged 7 to 18 and the Center for Epidemiologic Studies Depression Scale (CES-D) for physical activity and depressive symptoms. Multivariate Logistic regression analysis was used to analyze the correlation between physical activity and depressive symptoms in adolescents.@*Results@#The proportion of adolescents who met moderate to vigorous physical activity (MVPA) standard was 37.0%, and the detection rate of depressive symptoms was 25.6%. The detection rate of depressive symptomsin compliant with MVPA standard group was significantly lower than that in non compliant group among different age and gender( χ 2=7.62-34.54, P <0.05). Adolescents with severe depressive symptoms had high light intensity physical activity(LPA) duration and low vigorous intensity physical activity(VPA) duration, while adolescents with mild depressive symptoms or asymptomatic adolescents had higher MVPA duration. There were differences in LPA and VPA among adolescents with different levels of depressive symptoms in the overall sample, and the differences were still significant among girls, middle school and statistically significant differences in LPA, moderate intensity physical activity(MPA), MVPA were also found among the high school subgroup. However, differences only in LPA were observed among boys with different levels of depression( H=46.48, 10.31, 25.02, 29.54, 30.25, 19.80, 22.20, 9.54, 8.62, 18.06, P <0.05). Multivariate Logistic regression model showed that gender and duration of MVPA were significantly related to risk of depressive symptoms( OR=1.56, 1.42, P <0.05).@*Conclusion@#Physical activity among adolescents is significantly related to depressive symptoms. MVPA may be an effective measure to reduce the degree of depressive symptoms.To improve the physical health and prevent depression among adolescents, it is important to choose appropriate physical activity types and effectively increase the duration of MVPA.

ABSTRACT

Objective@#To explore the correlation between different nutritional status and depressive symptoms among adolescents, so as to provide a theoretical basis for targeted improvement of nutritional status and depressive symptoms in adolescents.@*Methods@#A total of 8 102 adolescents aged 12-17 years in Shanghai, Urumqi, Changsha and Kunming were selected by random cluster sampling. Depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale(CES-D). Height and weight were measured. Kruskal Wallis H test, Chi square test and ordinal Logistic regression were used to analyze the relationship between nutritional status and depressive symptoms in adolescents.@*Results@#The overall detection rate of depressive symptoms in adolescents was 25.6%, with girls (30.1%) higher than that of boys (21.1%) ( χ 2=87.60, P <0.01). There were statistically significant differences in the scores of depressive symptoms among girls with different nutritional status ( Z =8.34, P <0.05). The detectable rate of depressive symptoms increased with BMI among girls( χ 2 trend =6.04, P <0.05). After controlling for confounding factors, ordinal Logistic regression showed that the obese girls had higher risks in depressive symptoms detection compared with normal weight girls ( OR=1.45, 95%CI=1.10-1.91, P <0.05).@*Conclusion@#The nutritional status of girls is better than boys, but the prevalence of depressive symptoms is higher than boys. The risk of depressive symptoms in girls increases with BMI.

ABSTRACT

Objective To investigate related influencing factors in patients with type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD). Methods A total of 252 patients with T2DM who were treated in Shanghai Baoshan Hospital of Integrated Traditional Chinese and Western Medicine from May 2021 to March 2022 were enrolled as subjects, and these patients were also included in Metabolic Management Center of China. According to the presence or absence of fatty liver disease, the patients were divided into simple T2DM group ( n =105) and T2DM+NAFLD group ( n =147). Related general data were analyzed, including sex, age, blood pressure, body height, body weight, neck circumference, triglyceride (TG), total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, fasting blood glucose, glycosylated hemoglobin, high-sensitivity C-reactive protein, albumin/creatinine ratio in morning urine, thyroid stimulating hormone, uric acid, intrahepatic fat deposition, carotid intima-media thickness, and brachial-ankle pulse wave velocity. The group t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between groups. A multivariate logistic regression analysis was used to investigate the risk factors for T2DM with NAFLD, and the receiver operating characteristic (ROC) curve was used to assess the predictive value of related influencing factors. Results The age-stratified analysis showed that in the < 50 years age group, compared with the patients with T2DM alone, the patients with T2DM and NAFLD had significantly higher levels of body mass index (BMI), visceral fat, TG, brachial-ankle pulse wave velocity, albumin/creatinine ratio in morning urine, and uric acid ( P < 0.05); in the ≥50 years age group, compared with the patients with T2DM alone, the patients with T2DM and NAFLD had significantly higher levels of blood pressure, BMI, visceral fat, TG, brachial-ankle pulse wave velocity, albumin/creatinine ratio in morning urine, and uric acid ( P < 0.05) and a significantly lower level of serum HDL-C ( P < 0.05). The multivariate logistic regression analysis showed that BMI (odds ratio [ OR ]=1.408, 95% confidence interval [ CI ]: 1.136-1.746, P =0.002), HDL-C ( OR =0.031, 95% CI : 0.001-0.647, P =0.025), left brachial-ankle pulse wave velocity ( OR =1.003, 95% CI : 1.001-1.006, P =0.003), and uric acid ( OR =1.011, 95% CI : 1.005-1.016, P < 0.001) were independent influencing factors for T2DM with NAFLD. The ROC curve analysis showed that HDL-C, BMI, left brachial-ankle pulse wave velocity, and uric acid had an area under the ROC curve of 0.695 (95% CI : 0.574-0.812), 0.708 (95% CI : 0.628-0.788), 0.611 (95% CI : 0.523-0.698), and 0.698 (95% CI : 0.617-0.779), respectively, in evaluating T2DM with NAFLD. Conclusion Low levels of HDL-C, BMI, left brachial-ankle pulse wave velocity, and uric acid have a certain value in predicting NAFLD in patients with T2DM.
