OBJECTIVES: Whether vortioxetine has a utility as an adjuvant drug in the treatment of bipolar depression remains controversial. This study aimed to validate the efficacy and safety of vortioxetine in bipolar depression. METHODS: Patients with bipolar Ⅱ depression were enrolled in this prospective, two-center, randomized, 12-week pilot trial. The main indicator for assessing treatment effectiveness was a Montgomery-Asberg Depression Rating Scale (MADRS) of ≥50%. All eligible patients initially received four weeks of lurasidone monotherapy. Patients who responded well continued to receive this kind of monotherapy. However, no-response patients were randomly assigned to either valproate or vortioxetine treatment for eight weeks. By comprehensively comparing the results of MADRS over a period of 4‍‒‍12 weeks, a systematic analysis was conducted to determine whether vortioxetine could be used as an adjuvant drug for treating bipolar depression. RESULTS: Thirty-seven patients responded to lurasidone monotherapy, and 60 patients were randomly assigned to the valproate or vortioxetine group for eight weeks. After two weeks of combined valproate or vortioxetine treatment, the MADRS score in the vortioxetine group was significantly lower than that in the valproate group. There was no difference in the MADRS scores between the two groups at 8 and 12 weeks. The incidence of side effects did not significantly differ between the valproate and vortioxetine groups. Importantly, three patients in the vortioxetine group appeared to switch to mania or hypomania. CONCLUSIONS This study suggested that lurasidone combination with vortioxetine might have potential benefits to bipolar II depression in the early stage, while disease progression should be monitored closely for the risk of switching to mania.

A growing interest in the comprehensive pathogenic mechanisms of psychiatric disorders from the perspective of the microbiome has been witnessed in recent decades; the intrinsic link between microbiota and brain function through the microbiota-gut-brain axis or other pathways has gradually been realized. However, little research has focused on viruses-entities characterized by smaller dimensions, simpler structures, greater diversity, and more intricate interactions with their surrounding milieu compared to bacteria. To date, alterations in several populations of bacteriophages and viruses have been documented in both mouse models and patients with psychiatric disorders, including schizophrenia, major depressive disorder, autism spectrum disorder, and Alzheimer's disease, accompanied by metabolic disruptions that may directly or indirectly impact brain function. In addition, eukaryotic virus infection-mediated brain dysfunction provides insights into the psychiatric pathology involving viruses. Efforts towards virus-based diagnostic and therapeutic approaches have primarily been documented. However, limitations due to the lack of large-scale cohort studies, reliability, clinical applicability, and the unclear role of viruses in microbiota interactions pose a challenge for future studies. Nevertheless, it is conceivable that investigations into viruses herald a new era in the field of precise psychiatry.

Objective:To carry out evidence-based nursing for standardized management of stress hyperglycemia in perioperative period of gastrointestinal tumor patients, and to formulate indicators, analyze obstacles and promoting factors, formulate action strategies.Methods:Guided by the Johns Hopkins evidence-based nursing model, evidence were searched, evaluated and summarized. Clinical indicators and review methods were formulated to carry out quality review. From November 2021 to April 2022, the medical staff and patients in the gastrointestinal surgery department of the First Affiliated Hospital of Anhui Medical University who met the inclusion criteria were conducted, and the incidence of compliance rate was calculated. Based on the results of the baseline review, the obstacles and contributing factors were analyzed.Results:A total of 26 pieces of best evidence were included and 14 indicators were formulated for 48 medical staff and 45 patients to clinical review, among which the compliance rate of 7 indicators was less than 60%. The main obstacle factors were lack of procedures and instruments for management of perioperative stress hyperglycemia in gastrointestinal tumor patients, lack of knowledge of medical staff, etc. The main promoting factors were organizational support, good atmosphere of medical team cooperation, strong willingness to change, etc.Conclusions:There is a big gap between the clinical practice and the best evidence of perioperative stress hyperglycemia management in patients with gastrointestinal tumor. Action strategies should be put forward for obstacles and promoting factors to promote evidence transformation.

Objective To observe the effect of acupoint sticking therapy along meridians on gastrointestinal function recovery in patients after lumbar internal fixation surgery.Methods From January 2020 to March 2022,125 patients with lumbar degenerative diseases were admitted to our hospital's Department of Orthopaedics and divided into two groups:control(n = 62)and acupoint sticking therapy(n = 63).The control group received standard postoperative care for lumbar internal fixation,while the experimental group received routine care based on acupoint sticking therapy along meridians.The NVAS scores for postoperative nausea and vomiting,abdominal distension and pain,bowel sound,initial exhaust,and defecation time were compared between the two groups.Results Both groups experienced gastrointestinal problems to varied degrees following surgery.The experimental group had signifi-cantly lower rates of nausea,NVAS score,vomiting grade,abdominal distension,return to normal bowel sounds,and time of first exhaust and bowel movement compared to the control group(P<0.05).However,there were no significant differences in abdominal pain and abdominal circumference(P>0.05).There were no adverse reactions in either group.The incidence of postoperative abdominal distension,nausea and vomiting in the observation group was lower than that in the control group,and the difference was statistically significant(P<0.05).Conclusion Acupoint sticking therapy along meridians could accelerate the recovery of gastrointestinal function of patients after lumbar internal fixation,promote rapid recovery after surgery,and improve quality of life.

Objective To investigate the status quo of cancer-related fatigue(CRF)in patients with advanced malignant tumours during anti-tumour treatment,and explore the influencing factors so as to provide a reference for nursing intervention.Methods Between January and August 2022,a total of 279 patients with advanced malignant tumours who received anti-tumour therapies in the Department of Oncology of a general hospital in Beijing were selected as study subjects using convenience sampling method.General data questionnaire,cancer fatigue scale,chemotherapy-related gastrointestinal symptoms inventory,and nutritional risk screening 2002 were used for the investigation.Logistic regression analysis was conducted to determine the influencing factors of cancer-related fatigue.Results Toally 279 patients finished the study.A total of 204(73.12%)patients had cancer-related fatigue.Binary logistic regression analysis showed that BMI,education,monthly family income and diabetes were the influencing factors in cancer-related fatigue(all P<0.05).Conclusions The incidence of cancer-related fatigue is high in patients with advanced malignant tumours during anti-tumour therapy.Low BMI,poor education,low monthly family income and diabetes are the risk factors in cancer-related fatigue.Targeted interventions should be implemented based on the risk factors so as to reduce the incidence of cancer-related fatigue.

Objective To explore the application of nurse-performed point-of-care ultrasound in abdominal distension of ICU patients with enteral nutrition.Methods Purposive sampling method was used to select 108 patients with enteral nutrition abdominal distension admitted to the ICU of a tertiary A general hospital in Hefei City from January to December 2022,and they were divided into an experimental group and a control group according to random number table method.The experimental group used bedside ultrasound to evaluate the stomach,intestine and abdominal cavity of patients with abdominal distension,and implemented targeted treatment measures according to the evaluation results.The control group was given corresponding treatment measures according to the abdominal sight,touch,tapping,listening and traditional syringe withdrawal method.Intra-abdominal pressure,abdominal circumference,feeding compliance rate and feeding interruption rate,ICU stay time and mechanical ventilation time were compared at the 1st,3rd and 5th day.Results 11 cases dropped out of the study due to transfer,automatic discharge,death,etc.,and 97 cases were included 51 cases in the experimental group and 46 cases in the control group.Repeated measurement ANOVA showed that intra-abdominal pressure and abdominal circumference time in the 2 groups had interaction with each other(F=41.724,P＜0.001;F=17.762,P＜0.001).Generalised estimating equations showed that there was only a between-group effect for the rates of feeding compliance and feeding disruption in 2 groups(Wald y2=18.033,P＜0.001;Wald x2=6.567,P＜0.001).Simple effect analysis showed that on the 3rd and 5th day after intervention.The experimental group had lower abdominal depression and the feeding interruption rate was lower than the control group(P＜0.05).On the 5th day after interven-tion,the abdominal circumference of the experimental group was lower than that of the control group,the feeding compliance rate was higher than that of control group(P＜0.05).After intervention,in the experimental group,the mechanical ventilation time was shorter than that of the control group(P＜0.05).There was no significant difference in ICU stay time between the 2 groups(P=0.095).Conclusion The application of nurse-performed point-of-care ultrasound in the management of abdominal distension in patients with enteral nutrition in ICU is feasible and scientific,which is helpful for the management of patients with enteral nutrition abdominal distension in ICU,reducing internal abdominal pressure,shortening mechanical ventilation time,and avoiding the occurrence of feeding intolerance.

Objective:To observe the effect of metformin on intestinal metabolites and its protective effect on lung injury in an elderly sepsis rat.Methods:SD rats were fed at the Animal Laboratory Center of Zhengzhou University, fourteen elderly SD rats were randomly divided into three groups: sham surgery (age-Sham, AgS group, n=4), cecal ligation and perforation induced sepsis (age-Cecal ligation and puncture, AgCLP group, n=5), and oral administration of metformin (100 mg/kg) after 1 h of CLP treatment (age-Metformin, AgMET group, n=5). Collected rat feces 24 h after modeling, and analyzed the composition and inter group differences of metabolites in the feces using liquid chromatography tandem mass spectrometry non targeted metabolomics. Collected rat lung tissues and detected the expression levels of inflammation related genes and pathological changes in the tissue. The visualization of metabolic changes between groups were presented using orthogonal partial least squares discriminant analysis, heatmaps, and unsupervised principal component analysis, respectively. MetaboAnalyst 3.0 was used to evaluate the Pathway analysis of metabolites, and this software was based on the KEGG database and the human metabolome database. Results:The expressions of CCL4 ( F=203.00, P<0.001), CXCL1( F=65.69, P<0.001), IL-6 ( F=38.94, P<0.002), TNF-α ( F=14.85, P=0.005) between two groups of rats were significantly different (all P<0.05). However, there was no significant difference in CCL2 expression between AgCLP group and AgMET group. Furthermore, compared with the AgS group, the relative intensities of 17 metabolites such as 7-methylxanthine, N-Arachidonylglycine and Manolide in AgCLP group were significantly increased, whereas the 9 metabolites such as Phenazone, Gly-Phe and Valyproline were significantly decreased, and metformin treatment could reverse these changes of the above metabolites. Correlation analysis showed that the IL-6 and TNF-α levels were positively correlated with the relative strength of 7-Methylxanthine, N-Arachidonylglycine and other metabolites, but negatively correlated with the Phenazone and Gly-Phe. CCL4 and CXCL1 were positively correlated with Manolide, but negatively correlated with Valyproline. Conclusion:The results of this study showed that metformin improved sepsis induced acute lung injury and regulates the host intestinal metabolites, which might provide a potential and effective treatment for elderly sepsis induced acute lung injury.

Objective:To clarify the effect and the mechanism of G protein-coupled receptor class C group 5 member A (GPRC5A) on lipopolysaccharide (LPS)-induced inflammatory response in human gingival fibroblasts (GFs), thus to provide a foundation for delving into the role of G protein coupled receptor (GPCR) in periodontitis.Methods:Gingival tissue samples were collected from 3 individuals periodontally healthy (health group) and 3 patients with periodontitis (periodontitis group) in Shandong Stomatological Hospital from December 2022 to February 2023. The expressions of GPRC5A of the two groups were detected by immunohistochemistry staining. GFs used in this study were isolated from a portion of gingiva for the extraction of impacted teeth in School and Hospital of Stomatology, Cheeloo College of Medicine, Shandong University from December 2022 to February 2023. GFs were isolated with enzymic digestion and transfected with 30, 50 and 80 μmol/L small interfering RNA-GPRC5A (siGPRC5A) or small interfering RNA-negative control (siNC), regarded as the experimental group and the negative control one, respectively. The silencing efficiency of siGPRC5A was evaluated by real-time fluorescence quantitative PCR (RT-qPCR). Experiments were then conducted using these cells which were divided into four groups of negative control (NC), LPS, siGPRC5A+LPS and siGPRC5A. The mRNA and protein levels of GPRC5A in GFs under 1 mg/L LPS-induced GFs inflammatory state were evaluated by RT-qPCR and Western blotting analysis after GPRC5A knockdown. RT-qPCR was used to detect the gene expression levels of the inflammatory cytokines in GFs induced by LPS, namely, interleukin (IL)-1β, IL-6, IL-8, tumor necrosis factor (TNF)-α, prostaglandin endoperoxide synthase 2 (PTGS2) after GPRC5A knockdown. Western blotting analysis and immunofluorescence staining were used to further investigate the activation of nuclear factor-kappa B (NF-κB) signaling pathway.Results:Immunohistochemistry staining showed that the expression of GPRC5A in gingival tissues of periodontitis group (0.132±0.006) increased compared with that in periodontally healthy group (0.036±0.019) ( t=8.24, P=0.001). Meanwhile, RT-qPCR results showed that the gene expression levels of GPRC5A at different time point (2, 6, 12, 24 h) in LPS-induced GFs (0.026±0.002, 0.042±0.005, 0.004±0.000, 0.016±0.000) were upregulated compared with those in the NC group (0.004±0.000, 0.004±0.000, 0.002±0.000, 0.007±0.000) (all P<0.001), respectively, and peaked at 6 h. The 50 μmol/L group displayed the most significant decrease in siGPRC5A expression (31.16±3.29) compared with that of the siNC group (100.00±4.88) ( F=297.98, P<0.001). The results of RT-qPCR and Western blotting analysis showed that siGPRC5A (0.27±0.03, 0.71±0.00) suppressed the expressions of GPRC5A at both gene and protein levels, while LPS (1.30±0.10, 1.43±0.03) was able to promote the expressions of GPRC5A compared with those of the NC group (1.00±0.01, 1.00±0.00)(all P<0.001). The siGPRC5A+LPS group (0.39±0.03, 1.06±0.16) also inhibited the increase of GPRC5A at both gene and protein levels induced by LPS (1.30±0.10, 1.43±0.03) ( F=208.38, P<0.001; F=42.04, P<0.001). RT-qPCR results showed that the expressions of IL-8, IL-1β, IL-6, TNF-α, and PTGS2 at the gene level in LPS group were highly increased compared with those in the NC group (all P<0.001). siGPRC5A significantly suppressed LPS-induced expressions of these inflammatory cytokines in GFs (all P<0.001). Western blotting analysis showed that the levels of p65 and IκBα protein phosphorylation in the LPS group were highly increased compared with those in the NC group, and siGPRC5A could effectively suppressed LPS-induced protein phosphorylation (all P<0.01). Furthermore, immunofluorescence staining showed that NF-κB p65 in the control group was mainly concentrated in the cytoplasm, and partially translocated to the nucleus under the stimulation of LPS. siGPRC5A was able to inhibit LPS-induced intranuclear translocation of p65 to a certain extent. Conclusions:GPRC5A expression was upregulated in periodontitis, and GPRC5A knockdown inhibited LPS-induced inflammation. Moreover, GPRC5A played a role in inflammation regulation by interacting with NF-κB signaling pathway.
