Plain language summary
Stroke refers to a clinical syndrome of localized or global brain dysfunction caused by cerebrovascular disease. It has the characteristics of rapid onset, high morbidity, high mortality, and high disability. After a stroke, various dysfunction can be caused, and dysphagia is one of the most common symptoms. The acidity of vitamin C can promote the secretion of saliva by stimulating the tongue, which can accelerate the swallowing action, thereby improving the swallowing function. The aim of this study was to explore the effects of vitamin C stimulation on the rehabilitation process, Nourishment State Index and immune function indicator of stroke patients with dysphagia. This study is a randomised controlled trial which enrolled 120 participants with dysphagia. The participants were randomly assigned into control group and vitamin C stimulation group, with 60 cases in each group. Results show that vitamin C acid stimulation significantly improves rehabilitation, and the Nourishment State Index and Immune Function Index of stroke patients with dysphagia. Authors conclude that Vitamin C acid stimulation can further improve the nutritional status and immune function after stroke and promote post-operative recovery of patients. Thus, vitamin C stimulation therapy can be widely used in stroke rehabilitation management.
Abstract
BACKGROUND Stroke is a clinical syndrome of localized or global brain dysfunction caused by cerebrovascular disease. AIM: The aim of this study was to explore the effect of vitamin C acid stimulation on the rehabilitation process, Nourishment State Index and immune function indicators of stroke patients with dysphagia. DESIGN This is a prospective cohort study. SETTING This study was conducted at our hospital. POPULATION We analyzed stroke patients with dysphagia. METHODS A total of 120 stroke patients with dysphagia were randomly divided into a routine group and a test group, with 60 cases in each group. Routine swallowing training was performed in the routine group, and the test group was stimulated with vitamin C acid. The water swallow test (WST) and video fluoroscopic swallowing study (VFSS) were used to compare the rehabilitation of dysphagia in the two groups. Nourishment State Index was evaluated by BMI, serum albumin, total serum protein and hemoglobin. Immune Function Index was evaluated by IgA, IgM and IgG. RESULTS Compared with the control group, the WST level of patients treated with vitamin C acid stimulation intervention were significantly reduced, and the VFSS score were significantly increased. Serum levels of hemoglobin, albumin, total protein, IgA, IgM and IgG in the vitamin C acid stimulation group were remarkably increased than those in the control group. CONCLUSIONS Vitamin C acid stimulation exhibits a good application effect in patients with dysphagia after stroke. Moreover, vitamin C acid stimulation can further improve the nutritional status and immune function after stroke and promote postoperative recovery of patients. Therefore, we believe that vitamin C stimulation therapy can be widely used in stroke rehabilitation management. CLINICAL REHABILITATION IMPACT Vitamin C acid stimulation significantly improves rehabilitation of stroke patients with dysphagia and ameliorates the nutritional status and immune function of patients.

Plain language summary
Endometriosis (EMS) is a chronic and estrogen-dependent pelvic inflammatory disease that arises from ectopic endometrial implantation and growth outside the uterus cavity. Oxidative stress, an imbalance between reactive oxygen spices and biological antioxidants, could play a key role in EMS pathophysiology. The aim of this study was to evaluate the effect of vitamin C and vitamin E coadministration on oxidative stress (OS) markers as well as pain severity in women with endometriosis. This study is a randomized placebo-controlled clinical trial on 60 reproductive-aged (15–45 years) women with pelvic pain and 1–3 stages of laparoscopic-proven endometriosis. The participants, researchers, and statistician were blind about the groups. The participants were randomly assigned to two groups by the simple randomization method: group A - intervention (n = 30) or group B - palcebo (n = 30). Results show that supplementation with vitamin C and vitamin E effectively reduces systemic OS indices in women with endometriosis. Authors conclude that their findings further support the potential role of antioxidants in the management of EMS.
Abstract
Background: Endometriosis is a chronic and estrogen-dependent pelvic inflammatory disease, which may have various causes, such as oxidative stress. Dysmenorrhea, dyspareunia, and pelvic pain are well-known symptoms of endometriosis. The present clinical trial assessed the role of supplementation with antioxidant vitamins on the indices of oxidative stress as well as the severity of pain in women with endometriosis. Materials and Methods: We enrolled 60 reproductive-aged (15-45 years) women with pelvic pain in this triple-blind clinical trial. They had 1-3 stages of laparoscopic-proven endometriosis. The participants were randomized to group A (n = 30), given vitamin C (1000 mg/day, 2 tablets of 500 mg each) and vitamin E (800 IU/day, 2 tablets of 400 IU each) combination, or group B (n = 30), given placebo pills daily for 8 weeks. Results: Following treatment with vitamin C and vitamin E, we found a significant reduction in MDA and ROS compared with the placebo group. There was no significant decline in total antioxidant capacity after treatment. However, the severity of pelvic pain (p value <0.001), dysmenorrhea (p value <0.001), and dyspareunia (p value <0.001) significantly decreased in the treatment group after 8 weeks of supplementation. Conclusions: The present findings support the potential role of antioxidants in the management of endometriosis. The intake of vitamin C and vitamin E supplements effectively reduced dysmenorrhea severity and improved dyspareunia and severity of pelvic pain.
