Objective:To explore the mediating effect of attitudes to aging between intergenerational support and health behavior in elderly stroke patients.Methods:From March 2023 to February 2024, elderly stroke patients hospitalized in the Department of Neurology at Beijing Tongren Hospital, Capital Medical University, were selected as study subjects using convenience sampling. The survey was conducted using the General Information Questionnaire, Attitudes to Ageing Questionnaire (AAQ), Intergenerational Support Scale (ISS), and Stroke Health Behavior Questionnaire (SHBQ). Pearson correlation was employed to analyze the relationships among attitudes to aging, intergenerational support, and health behavior. AMOS 21.0 software was used to construct the structural equation model and verify the mediating effect.Results:A total of 250 questionnaires were distributed, and 243 valid questionnaires were collected, with a valid response rate of 97.20%. The AAQ, ISS, and SHBQ scores of 243 elderly stroke patients were (70.57±9.03), (19.74±3.65), and (71.67±5.50), respectively. Attitudes to aging were positively correlated with both intergenerational support and health behavior ( P<0.05), and intergenerational support was positively correlated with health behavior ( P<0.05). Intergenerational support had a direct positive effect on health behavior (β=0.552), and attitudes to aging had a direct positive effect on health behavior (β=0.632). Attitudes to aging partially mediated the relationship between intergenerational support and health behavior, accounting for 38.12% (0.340/0.892) of the total effect. Conclusions:Attitudes to aging partially mediates the relationship between intergenerational support and health behavior. Improving intergenerational support may foster positive attitudes to aging, thereby promoting the development of healthy behavior among elderly stroke patients.

OBJECTIVE：To esta blish a method for si multaneous determination of 5 components in the branch and root of Juglans mandshurica as gallic acid ，ellagic acid ，1，6-di-O-galloyl-β-D-glucose，1，2，6-tri-O-galloyl-β-D-glucose and 1，2，3， 6-tetra-O-galloyl-β-D-glucose，and to analyze the content difference of above 5 components between the branch and root samples. METHODS：HPLC method was adopted. The determination was performed on Agilent Poroshell 120 SB-C18 column with mobile phase consisted of water （containing 0.2％ formic acid ）-acetonitrile （containing 0.2％ formic acid ）. A gradient elution was performed at a flow rate of 0.3 mL/min. The column temperature was 30 ℃ and the detection wavelength was 270 nm. The sample size was 5 μL. Independent samples t-test and partial least squares-discriminant analysis （PLS-DA）were applied for statistical analysis of 5 components. RESULTS ：The linear range of gallic acid ，ellagic acid ，1，6-di-O-galloyl-β-D-glucose，1，2， 6-tri-O-galloyl-β-D-glucose and 1，2，3，6-tetra-O-galloyl-β-D-glucose were 0.989-63.3，1.58-101，1.01-64.7，3.31-212，3.34-214 μg/mL （r≥0.997 3），respectively. RSDs of precision ，reproducibility and stability tests （12 h）were all lower than 3.2％. The average recoveries of the 5 components were 103.2％（RSD＝4.85％），99.1％（RSD＝2.80％），101.5％（RSD＝1.31％），102.9％（RSD＝ 2.73％）and 104.7％（RSD＝1.28％），respectively. The average contents of the above components in the branch of J. mandshurica were 0.296 5，0.621 1，0.562 5，3.111 7 and 3.451 3 mg/g，respectively. The average contents of above components in the root were 0.673 4，2.755 5，0.964 0，2.946 6 and 4.836 4 mg/g，respectively. The total contents of the 5 components in the branch and roo t of J. mandshurica were 8.043 2 and 12.175 9 mg/g，respectively. The contents of gallic acid ，ellagic acid and 1，6-di-O-galloyl- β-D-glucose in roots were significantly higher than those in branches （P＜0.05 or P＜0.01）. There were no significant differences in the contents of the other 2 components and the total contents of the 5 components in branches and roots （P＞0.05）. The cumulative interpretability （R 2X，R 2Y） and cumulative predictability （Q 2） of the model established by PLS-DA were 0.943，0.745，and 0.710 respectively. The model load diagram showed that the distance between the ellagic acid and the origin was the farthest ，and only variable projection importance of the content of the ellagic acid was greater than 1. CONCLUSIONS：The established method can be used for the content determination of 5 components in the branch and root of J. mandshurica . Except for 1，2，6-tri-O-galloyl-β-D-glucose，the contents of other 4 components and total contents of the 5 components in the root of J. mandshurica are higher than those of the branch. Ellagic acid is selected as the potential marker for discriminating the branch and root samples.

The literature was analyzed on the improvement of motor sensory function, urination and defecation in myelitis treated with acupuncture and moxibustion and focused on the characteristics of the diagnosis and treatment. The literature on acupuncture and moxibustion treatment for myelitis was collected from CNKI, Wanfang, VIP and PubMed. The analysis included the characteristics of acupoint selection, methods of acupuncture and moxibustion, time of treatment, total treatment period, efficacy, follow-up, safety, etc. Totally, 26 articles were collected. The combined therapy of acupuncture and moxibustion was predominated (12/26, 46. 15%). For the motor and sensory impairment, the acupoints were mainly selected from the four limbs, the yangming meridians of hand and foot and those adjacent to the affected spinal segments and on the governor vessel as well as Jiaji (EX-B 2) points. For urinary impairment, the acupoints were selected mainly from the lower abdominal region on the conception vessel and the lumbosacral region on the bladder meridian. For the intestinal impairment, the acupoints were from the lower limb on the stomach meridian, the lower abdominal region on the conception vessel and the back points on the bladder meridian. The intervention started commonly in the first 3 months after onset. The total treatment period was in the range from 1 to 3 months. The efficacy of acupuncture and moxibustion was 69.19% to 82.56% for the improvement of motor sensory and urination, defecation function. The efficacy in follow-up was stable and the adverse reactions were not reported. It is viewed that on the basis of early diagnosis and active medication, acupuncture and moxibution achieve a certain of efficacy on the impairment of motor sensory function, urination and defecation. A clinical research is expected to further verify the efficacy.

The roots, barks, branches and pericarps of Juglans mandshurica were used as folk medicine in China and reputed for its treatment of several cancers, such as gastric cancer, liver cancer and leukemia. The extracts of the roots, branches, leaves and pericarps of J. mandshurica have been experimentally proved to show anti-tumor activities. Tannins, which exhibited antioxidant and anti-tumor activities, were the main constituents in J. mandshurica. In this paper, a simple spectrophotometric method was developed for the determination of total tannins in the roots, branches, leaves and pericarps of J. mandshurica collected in Dalian and Anshan of Liaoning Province. Gallic acid was used as standard compound and the content of total tannins was calculated as gallic acid equivalent. As a result of the method validation, a good linearity (r = 0.9997, n = 5) and a high recovery of gallic acid (99.02%, RSD 3.7%, n = 9) was achieved. Eight samples including four parts of J. mandshurica collected in two places were analyzed for their total tannins with the established method. In the corresponding parts of J. mandshurica, except the pericarps, the contents of total tannins showed no significant difference between samples collected in Dalian and Anshan, while the content of total tannins in different parts of J. mandshurica were significantly different. The average content of total tannins in the roots, branches, leaves and pericarps of samples collected in Dalian and Anshan was 45.66, 23.40, 58.24, 3.58 mg g(-1), respectively.

Objective To assess the feasibility of adenoviral vectors mediate cochlear gene transfer by postau-ricular microinjection through the round window membrane in mouse. Methods Twelve 5-week old C57BL/6J mice were selected for the study: 8 were implanted with Ad-EGFP by postauricular microinjection through the round window membrane, and 4 with artificial perilymphatic fluid. On postoperative days 5 and 14, the animals were sac-rificed and the surface preparation of cochleae was observed. Results Two animals died after operation. Bright green fluorescence in the cochleae was observed in Ad- EGFP groups. Gene expression on day 14 after operation was higher than that on day 5. However, the control group was free of fluorescence. Oonclusion The postauricular route of the cochlear gene transfer in mice is simple to operate with little side-effect. The technique of transgenic delivery into the inner ear through RWM by mieroinjection is feasible and effective.
