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 evaluate the long-term efficacy of transjugular intrahepatic portosystemic shunt(TIPS)with bare stents and Fluency covered stents in the treatment of portal hypertension,and to discuss its clinical value.Methods The clinical data of 29 patients with intractable ascites or esophagogastric fundus varices rupture and hemorrhage caused by cirrhotic portal hypertension,who received TIPS with bare stents and covered stents at the First Affiliated Hospital of Xinjiang Medical University of China(25 patients)and the Lishui Municipal Central Hospital of China(4 patients)between August 2012 and December 2017,were retrospectively analyzed.The patients were regularly followed up to check the survival status.The postoperative cumulative shunt patency rate and cumulative survival rate of the patients were analyzed by Kaplan-Meier method.Results The technical success rate of TIPS was 100％.The mean portal vein pressure was decreased from preoperative(40.21±3.24)cmH2O to postoperative(24.55±3.55)cmH2O(P＜0.05).The patients were followed up for 5.1-10.5 years.The postoperative 1-,3-,5-,7-year primary cumulative patency rates of the shunt were 89.7％,75.9％,75.9％ and 52.5％,respectively.The postoperative 5-,7-,9-and 10-year cumulative survival rates were 100％,66.9％,66.9％ and 33.4％,respectively.The incidence of hepatic encephalopathy was 13.8％(4/29).Conclusion Using bare stents combined with Fluency covered stents for TIPS is clinically safe and effective in the treatment of portal hypertension.This technique carries higher long-term shunt patency rate and low incidence of hepatic encephalopathy.Therefore,it can be used as a substitute for Viatorr stent when necessary.(J Intervent Radiol,2024,33:295-299)

Objective To evaluate the clinical application value of medical tissue glue in the treatment of acute hemoptysis by bronchial arterial embolization(BAE).Methods The clinical data of 78 patients who underwent emergency BAE for hemoptysis were retrospectively collected.Among them,18 patients who underwent embolization with medical tissue glue were selected as a study group,and other 18 patients who underwent embolization with absorbent gelatin sponge particles and spring coil were selected as a control group.The technical success rates,average surgical operation time,average surgical cost,postoperative hemoptysis recur-rence rate,and incidence of adverse reactions of the two groups were compared and analyzed.Results The technical success rates of the two groups were both 100％.There were no statistically significant differences in recurrence rate of postoperative hemoptysis and incidence of adverse reactions between the two groups(P＞0.05).The average surgical operation time of study group and control group were 53.4 min[(53.4±2.2)min]and 65.4 min[(65.4±2.8)min],and the average surgical cost were 3 651 yuan[(3 651±102.7)yuan]and 5 094 yuan[(5 094±136.3)yuan],respectively.Compared with the control group,the average surgical operation time and aver-age surgical cost of the study group were shorter,and the differences were statistically significant(P＜0.05).Conclusion Compared with absorbent gelatin sponge particles combined with spring coil embolization,the use of medical tissue glue for embolization is also safe and effective in the treatment of acute hemoptysis patients by BAE.The average surgical operation time is shorter,and the surgical cost for patients is lower.It is worth promoting in clinical practice.

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 explore the inhibitory effect of Sidaxue, a traditional Miao herbal medicine formula, on articular bone and cartilage destruction and synovial neovascularization in rats with collagen-induced arthritis (CIA). Methods In a SD rat model of CIA, we tested the effects of daily gavage of Sidaxue at low, moderate and high doses (10, 20, and 40 g/kg, respectively) for 21 days, with Tripterygium glycosides (GTW) as the positive control, on swelling in the hind limb plantar regions by arthritis index scoring. Pathologies in joint synovial membrane of the rats were observed with HE staining, and serum TNF-α and IL-1β levels were detected with ELISA. The expressions of NF-κB p65, matrix metalloproteinase 1 (MMP1), MMP2 and MMP9 at the mRNA and protein levels in the synovial tissues were detected using real-time PCR and Western blotting. Network pharmacology analysis was conducted to identify the important target proteins in the pathways correlated with the therapeutic effects of topical Sidaxue treatment for RA, and the core target proteins were screened by topological analysis. Results Treatment with GTW and Sidaxue at the 3 doses all significantly alleviated plantar swelling, lowered arthritis index scores, improved cartilage and bone damage and reduced neovascularization in CIA rats (P<0.05), and the effects of Sidaxue showed a dose dependence. Both GTW and Sidaxue treatments significantly lowered TNF-α, IL-1β, NF-κB p65, MMP1, MMP2, and MMP9 mRNA and protein expressions in the synovial tissues of CIA rats (P<0.05). Network pharmacological analysis identified MMPs as the core proteins associated with topical Sidaxue treatment of RA. Conclusion Sidaxue alleviates articular bone and cartilage damages and reduces synovial neovascularization in CIA rats possibly by downregulating MMPs via the TNF-α/IL-1β/NF-κB-MMP1, 2, 9 signaling pathway, and MMPs probably plays a key role in mediating the effect of Sidaxue though the therapeutic pathways other than oral administration.

Objective:To investigate the prognostic factors for all-cause mortality in patients with muscle-invasive bladder cancer(MIBC)with intermediate-to-high-risk primary prostate cancer.Methods:From January 2012 to October 2023,the clinical data of the patients with MIBC with intermediate-to-high-risk primary prostate cancer in Peking University Third Hospital were retrospectively analyzed.All the patients were monitored and the occurrence of all-cause death was documented as the outcome event in the prognostic study.Univariate and multivariate Cox proportional risk regression analysis models were implemented to search for independent influences on the prognosis of patients.For significant influencing factors(pathological T stage,M stage and perineural invasion of bladder cancer),survival curves were plotted before and after multifactorial Cox regression adjusting for confounding factors.Results:A total of 32 patients were included in this study.The mean age was(72.5±6.6)years;the median preoperative total prostate specific antigen(tPSA)was 6.68(2.47,6.84)μg/L;the mean preoperative creatinine was(95±36)μmol/L,and the median survival time was 65 months.The majority of the patients(87.5％)had high-grade bladder cancer,53.1％had lymphatic invasion,and 31.3％had perineural invasion.Prostate involvement was observed in 25.0％of the cases,and the positive rate of soft-tissue surgical margin was 37.5％.Multivariate Cox analysis revealed that preoperative creatinine level(HR=1.02,95％CI:1.01-1.04),pathological stage of bladder cancer T3(HR=11.58,95％CI:1.38-97.36)and T4(HR=19.53,95％CI:4.26-89.52)metastasis of bladder cancer(HR=9.44,95％CI:1.26-70.49)and perineural invasion of bladder cancer(HR=6.26,95％CI:1.39-28.27)were independent prognostic factors(P＜0.05).Survival curves with Log-rank test after adjusting for confounding factors demonstrated that bladder cancer pathology T3,T4,M1,and perineural invasion were unfavorable factors affecting the patients'survival prognosis(P＜0.05).Conclusion:Patients with MIBC with intermediate-to-high risk primary prostate cancer generally portends a poor prognosis.High preoperative serum creatinine,T3 or T4 pathological stage of bladder cancer,metastasis of bladder cancer and bladder cancer perineural invasion are poor prognostic factors for patients with MIBC with intermediate-to-high risk primary prostate cancer.
