AIM:To investigate the synergistic efficacy of travoprost and betahistine mesylate in early open angle glaucoma.METHODS:This study is a prospective, randomized, controlled, open label single center clinical trial that enrolled 82 patients(82 eyes)with early primary open-angle glaucoma from January 2020 to January 2023(eligible eyes were included, and the right eye was selected if both eyes met the inclusion criteria). The patients were randomly divided into a monotherapy group(41 eyes)treated with only travoprost eye drops and a combination therapy group(41 eyes)treated with travoprost eye drops and oral betahistine mesylate according to a 1:1 ratio using a random number table method. Followed-up for 12 mo, the intraocular pressure(IOP), retinal nerve fiber layer(RNFL)thickness, ocular hemodynamics [peak systolic velocity(PSV), end diastolic velocity(EDV), resistance index(RI), pulsatility index(PI)], liver and kidney function, quality of life, and clinical symptom scores before and after treatment were compared between the two groups of patients.RESULTS:Totally 4 patients were unable to complete all follow-up visits due to various factors, including 2 cases in the monotherapy group and 2 cases in the combination therapy group, with a lost rate of follow-up of 5%. The IOP in the combination therapy group was significantly lower than that in the monotherapy group at all time points(all P<0.05). Additionally, the rate of reduction in RNFL thickness was significantly slower in the combination therapy group compared to the monotherapy group(all P<0.05). Hemodynamic parameters revealed that PSV and EDV were significantly higher in the combination therapy group at 12 mo, while RI and PI were significantly lower than those in the monotherapy group(all P<0.05). The quality of life scores and visual analog scale(VAS)scores were also significantly better in the combination therapy group compared to the monotherapy group(all P<0.05). There were no statistically significant differences in liver functions, including alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bilirubin(TBIL), and kidney functions, including serum creatinine(Scr), blood urea nitrogen(BUN), and uric acid(UA)between the two groups at 6 and 12 mo after treatment, with no serious damage to liver and kidney or other systemic adverse reactions observed in either groups. Furthermore, the incidence of headache in the combination group was lower than that of the monotherapy group(P=0.042), and there were no statistical significance in the incidence of other adverse reactions(all P>0.05).CONCLUSION:The combination therapy of travoprost and betahistine mesylate exhibits significant synergistic effects in patients with early primary open angle glaucoma, offering better IOP control, neuroprotection of the optic nerve, and oxidative stress inhibition. This combination may provide a new clinical reference for comprehensive glaucoma treatment.

Objective:To compare the patient-reported outcomes and short-term clinical outcomes between robotic-assisted and laparoscopic-assisted radical gastrectomy for locally advanced gastric cancer.Methods:This single-center prospective randomized controlled trial was conducted in the Department of Gastrointestinal Surgery, Affiliated Hospital of Qingdao University from October 2020 to August 2022. Patients with locally advanced gastric cancer who were to undergo radical gastrectomy were selected and randomly divided into two groups according to 1∶1, and received robotic surgery and laparoscopic surgery, respectively. Patient-reported outcomes and short-term clinical outcomes (including postoperative complications, surgical quality and postoperative short-term recovery) were compared between the two groups by independent sample t test, Mann-Whitney U test, repeated ANOVA, generalized estimating equation, χ2 test and Fisher′s exact test. Results:A total of 237 patients were enrolled for modified intention-to-treat analysis (120 patients in the robotic group, 117 patients in the laparoscopic group). There were 180 males and 59 females, aged (63.0±10.2) years (range: 30 to 85 years). The incidence of postoperative complications was similar between the robotic group and laparoscopic group (16.7% (20/120) vs. 15.4% (18/117), χ2=0.072, P=0.788). The robotic group had higher patient-reported outcomes scores in general health status, emotional, and social domains compared to the laparoscopic group, differences in time effect, intervention effect, and interaction effect were statistically significant (general health status: χ2 value were 275.68, 3.91, 6.38, P value were <0.01, 0.048, 0.041; emotional: χ2 value were 77.79, 6.04, 6.15, P value were <0.01, 0.014, 0.046; social: χ2 value were 148.00, 7.57, 5.98, P value were <0.01, 0.006, 0.048). However, the financial burden of the robotic group was higher, the differences in time effect, intervention effect and interaction effect were statistically significant ( χ2 value were 156.24, 4.08, 36.56, P value were <0.01, 0.043,<0.01). Conclusion:Compared to the laparoscopic group, the robotic group could more effectively relieve postoperative negative emotions and improve recovery of social function in patients.

Objective:This study aimed to explore the clinical value of myostatin(MST) and follistatin(FST) as biological biomarkers in evaluating sarcopenia in elderly women.Methods:This was a retrospective cross-sectional study that enrolled 350 females aged 20-89 years who underwent physical examinations in Shanghai Huadong Hospital in 2021. Demographic characteristics, muscle mass, fat mass, bone mineral density, hand grip strength, gait speed, and serum indices of MST and FST were collected.Results:The serum levels of MST did not change significantly with age. However, the serum levels of FST increased with age. In women aged≥60 years, MST was positively correlated with total lean mass and appendicular skeletal muscle index(ASMI; r=0.236, P=0.041; r=0.289, P=0.014), while FST was negatively correlated with ASMI( r=-0.265, P=0.030). In multivariate stepwise regression analysis, after adjusting for age, body mass index, hip bone mineral density, and total fat mass, only FST was independently correlated with ASMI( β=-0.238, P=0.006), while MST was not correlated with ASMI. The receiver operating characteristic curve was plotted using muscle mass reduction as the state variable and serum FST level as the test variable. The area under the curve was 0.753. And when the FST cutoff value was 17.49 ng/mL, the maximum Jordan index was 0.46, with a sensitivity of 77.3% and a specificity of 68.7%. Women aged ≥60 years were divided into three groups based on serum FST levels. Compared to the upper third of the serum FST level group, the low third of the FST level group had a significantly reduced risk of suffering from sarcopenia( OR=0.098, P =0.036). Conclusions:Serum FST lever has a better correlation with muscle mass among elderly women, making it a promising biomarker for evaluating muscle mass.

Objective To observe the drainage pathways of interstitial fluid(ISF)and substance clearance pattern in rat brain with fluorescence tracing imaging and treacer-based MRI.Methods Thirty-three male SD rats were randomly divided into fluorescence tracing group(F group,n=18)and treacer-based MRI group(MRI group,n=15),then further divided into thalamic,hippocampal and caudate nucleus subgroups,respectively.Evans blue was injected to rats in F group,and cardiac perfusion was performed after injection,then brain tissue was harvested,and frozen sections were made to observe the drainage pathways of IFS in different subgroups.MRI was performed on rats in MRI group before and after injection of gadolinium-diethylenetriamine pentaacetic acid(Gd-DTPA)to observe signal intensity in ROI of brain regions in different subgroups,the signal unit ratio was calculated,and the changing trend was explored.Results ISF in thalamus,hippocampus and caudate nucleus had different dominant drainage pathways,and the time of tracer reached to adjacent brain regions and whole brain in F group were different.In MRI group,within 4 h after injection of Gd-DTPA,there were differences in direction and clearance rate among tracer in thalamus,hippocampus and caudate nucleus,mainly manifesting as the tracer in thalamus and hippocampus drained to the ipsilateral cortex and lateral ventricle,while the tracer in the caudate nucleus diffused to the cortex and midbrain,and there were differences of the peak time of tracer signal among adjacent drainage brain regions.Conclusion Fluorescence and MR dual-mode imaging showed that there were differences in the dominant drainage pathways of IFS and clearance rates of small molecule substances among hypothalamus,hippocampus and caudate nucleus of rats.

【Objective】 To establish a co-expression lncRNA-mRNA ceRNA network and explore the potential molecular mechanism of lncRNA in dengue fever. 【Methods】 DENV-2-infected and normal pHUVEC were sequenced and screened for differentially expressed lncRNA and mRNA by gene microarray technology. Differentially expressed mRNA was analyzed by protein-protein interaction (PPI), and significantly related co-expressed lncRNA-mRNA was screened by Pearson’s correlation coefficient. The microRNA (miRNA) that bound to co-expressed lncRNA-mRNA was predicted by the database. The ceRNA network of co-expressed lncRNA-mRNA was constructed by Cytoscape software. Finally differentially expressed mRNAs and co-expressed lncRNA-mRNA were analyzed by GO and KEGG enrichment, and co-expressed lncRNA-mRNA was verified by RT-qPCR. 【Results】 At 48 h and 72 h after infection, 105 and 51 differentially expressed mRNAs were obtained, respectively, while 59 and 29 differentially expressed lncRNAs were obtained, respectively. Furthermore, at the two time intervals, there were 10 differential mRNAs and 5 differential lncRNAs, respectively. PPI analysis of differential mRNAs showed that isocratic values of interleukin 6 (IL6), interferon-induced protein with tetratricopeptide repeats 2 (IFIT2), and 2’-5’-oligoadenylate synthetase 2 (OAS2) were relatively high. The pairing results of lncRNA-mRNA co-expression analysis with the highest correlation coefficients at 48 h and 72 h after infection were XLOC_001966-SMTNL1 and XLOC_001966-ESR2, respectively. According to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis, the functions of differentially expressed mRNA and co-expressed lncRNA-mRNA were mainly involved in virus epidemic prevention response, immune response, and signal transduction, as well as the Janus kinase (JAK)-signal transducer and activator of transcription (STAT) signaling pathway, type I interferon, and cytokine receptor interaction. RT-qPCR revealed that lncRNA XLOC-I2-8991 was upregulated in the co-expressed lncRNA-mRNA, whereas all the other lncRNA and mRNA were downregulated. 【Conclusion】 This study initially revealed the potential lncRNA-mRNA co-expression network during dengue virus infection, and found that co-expressed lncRNA-mRNA was mainly enriched in the immune regulation and signal transduction pathways during virus infection. The findings will help further exploration into the infection mechanism of DENV-2.

Objective:To evaluate the clinical effects of problem solving therapy on the elderly patients with depression by Meta-analysis.Methods:Randomized controlled trials articles regarding the effects of problem solving therapy on the elderly patients with depression were searched from the database of PubMed, EMbase, Medline, Cochrane Library, China National Knowledge Infrastructure, Chinese Biomedical Database and Wanfang Data electronically. SMD was used as the post merger response, and its 95% CI was calculated. Results:Ten articles were recruited and a total of 1 005 patients were included, 501 patients in the intervention group and 504 patients in the control group. Meta-analysis showed that problem solving therapy was significantly better than the control group in the treatment of depressive symptoms in the elderly patients with depression ( SMD =-0.64, 95% CI -0.98 - -0.31, P<0.05); during the follow-up within 3 months and 6 months after the intervention, the improvement of depression in the intervention group was better than that in the control group ( SMD=-0.62, 95% CI -1.00 - -0.25, P<0.05) and ( SMD =-0.79, 95% CI -1.03 - -0.55, P<0.05), respectively. Compared with the control group, the intervention group had an effect on the improvement of dysfunction ( SMD=-1.28, 95% CI -2.22 - -0.35, P<0.05). Conclusions:Problem solving therapy can improve the depressive symptoms of the elderly patients with depression and the clinical effect remains stable for a certain period of time; problem solving therapy has an improvement effect on the dysfunction of the elderly patients with depression.

The psychological distress of cancer patients seriously affects their therapeutic effects. Effective psychological rehabilitation of cancer patients significantly improves their survival chance and quality of life. Circadian rhythm results from adaptation to the environment during the organism's evolution. When the endogenous clock system is disrupted or the external environment is changed, the body and the environment are out of synchronization, and the circadian rhythm will be disrupted. Circadian rhythm disorder is a common phenomenon in cancer patients, and the changes of circadian rhythm are closely related to their psychological distress. Many studies believe that the circadian rhythm disorder of cancer patients may directly or indirectly affect their psychology through various mechanisms, and targeted intervention by regulating the circadian rhythm of patients may be an essential means to promote the psychological rehabilitation.

Gastric schwannoma is a tumor originating from mesenchymal tissue. The clinical incidence is relatively rare, accounting for 6.3% of all gastric stromal tumors. The tumor is more likely to occur in the body of the stomach and usually originates from the gastric submucosal nerve. Most gastric schwannomas do not have any clinical symptoms. Imaging examination can play a diagnostic role, but the diagnosis still requires pathological examination, especially S-100 protein which is the gold standard for the diagnosis of gastric schwannomas. Gastric schwannoma usually needs to be distinguished from gastrointestinal stromal tumors and gastrointestinal autonomic nerve tumors. In terms of treatment, complete surgical resection is the first choice.
