Objective To choose a best cultivar by comparing the content of total flavonoid and naringin between different cultivars of Citrus grandis 'tomentosa'.Methods The content of total flavonoids was determined by spetral photometric analysis.The content of naringin was determined by HPLC.Results The content of total flavonoid was 19.24 % and 18.06 %,and naringin content was 11.72 % and 12.38 % in the cultivars from Dachaling and Fengwei respectively,which were much higher than the other cultivars.Conclusion The contents of total flavonoid and naringin were different in different cultivars of Citrus grandis 'tomentosa'.The cultivars of Citrus grandis 'tomentosa' from Dachaling and Fengwei have the best quality.

Sixty-fourth patients with vascular dementia were recruited in the study and randomly assigned in rehabilitation (medication plus rehabilitation)and control group (medication alone).The treatment period lasted for 12 weeks,the scorings of mini mental statement examination(MMSE) and activity of daily living scale (ADL) were compared before and 4,8,12 weeks after treatment in both group.The scorings of MMSE and ADL in rehabilitation group and control group were both improved after treatment(P ＜0.05),but the scorings in rehabilitation group were better than those in control group(P＜0.05).

OBJECTIVETo study the effects of nitrogen (N), phosphorus (P2O5), potassium (K2O) and organic compound fertilizer (OF) on spicas biomass and yield of Prunella vulgaris in order to provide a theoretical basis for good agriculture practice (GAP).

METHODField plot experiments with a 4-variable quadratic orthogonal rotation combination design were adopted, and a function model of spicas yield in P. vulgaris was established.

RESULTThe model analysis showed that spicas yields of P. vulgaris were significantly influenced under the N, P2O5 and K2O applications, among there factors, N had the greatest effects on spicas yield of P. vulgaris, the next was P2O5 and K2O, OF had the smallest effects on spicas yield. At the lower fertility levels, the spicas yields of P. vulgaris were improved along with the increasing of N, P2O5, K2O and OF applications, but the spicas yields decreased when N, P2O5, K2O and OF were applied too much.

CONCLUSIONIn this experiment condition, the spicas yields of P. vulgaris could reach to 722 kg x hm(-2) when the fertilizer rates were N 303. 9-335.1 kg x hm(-2), P2O5 432.5-500.6 kg x hm(-2), K2O 206.6-240.2 kg x hm(-2), OF 2 312.5-2 687.5 kg x hm(-2).

OBJECTIVETo study seed quality test, and establish seed quality classification standard of Prunella vulgaris.

METHODThe seed quality and planting quality of P. vulgaris from different population were measured and these indexes were analyzed by K-clustering.

RESULT AND CONCLUSIONThe seed purity, 1000 seeds weight, seed moisture content, seed viability of the seed of P. vulgaris from different population were measured, and the seed quality classification standard of P. vulgaris.

Objective To explore the efficacy of repeated transcranial magnetic stimulation(rTMS)combined with flupentixol and melitracen tablets on post-stroke depression(PSD)and to evaluate the predictive value of depressive symptom dimensions on the efficacy.Methods PSD patients diagnosed and treated in the department of rehabilitation medicine of Jiaozhou Central Hospital of Qingdao from January 2021 to December 2023 were selected as the research subjects,all patients were treated with rTMS combined with flupentixol and melitracen tablets.The National Institutes of Health Stroke Scale(NIHSS),Hamilton Depression(HAMD),and Barthel Index(BI)of PSD patients before and after treatment were evaluated and compared.PSD patients were divided into the effective group and the ineffective group based on treatment effectiveness,and Logistic regression was used to explore the relationship between depression symptom dimensions and treatment outcomes.Using the receiver operating characteristic(ROC)curve to explore the predictive value of depression symptom dimensions on the efficacy of PSD patients.Results A total of 80 PSD patients were included in this study,of which 68 cases were effective in treatment and 12 cases were ineffective in treatment.Compared with before treatment,PSD patients showed a significant decrease in HAMD score,NIHSS score(P＜0.05),and BI score was significant increased(P＜0.05).The observed mood(OM)score,cognitive score,and neurological symptom(NS)score of PSD patients in the effective group were higher than those in the ineffective group,and the differences were statistically significant(P＜0.05).Logistic regression analysis showed that high-level OM score,cognitive score,and NS score were independent protective factors for effective PSD treatment.ROC analysis showed that the baseline OM score,cognitive score,and NS score for ineffective treatment were 0.744[95％CI(0.568,0.921)],0.734[95％CI(0.572,0.896)],and 0.709[95％CI 0.534,0.884)],respectively.Conclusion rTMS combined with flupentixol and melitracen tablets can significantly improve depression symptoms and neurological impairment,and improve the ability of daily living.Moreover,depressive symptom dimensions at baseline can predict the treatment effects of PSD patients.

Objective:To assess the feasibility and efficacy of hypofractionated radiotherapy with simultaneous integrated boost (HFRT-SIB) for patients with non-osteogenic spinal metastases who were not suitable for stereotactic body radiotherapy (SBRT).Methods:A totoal of 26 spinal metastatic lesions in 24 patients with non-osteogenic spinal metastases admitted to Beijing Luhe Hospital affiliated to Capital Medical University from March 2020 to April 2023 were retrospectively analyzed. In our institution, a higher-dose fractionated regimen for spinal metastases was introduced, at a dose of 3 Gy/f ×10 times (5 times a week, once a day) to the clinical target volume (CTV), and simultaneous integrated boost (SIB) of 4 Gy/f ×10 times (5 times a week, once a day) to the gross tumor volume (GTV). The primary endpoint was the overall relief (OR) rates of pain at 12 and 24 weeks post-radiotherapy, while secondary endpoints included the pain response time and duration of pain relief, the incidence of adverse events post-radiotherapy, and the 1-year overall survival (OS) rate. The differences before and after treatment were analyzed by Wilcoxon signed-rank test. OS was assessed using Kaplan-Meier method.Results:The median follow-up was 11.7 (8.0, 17.0) months. At 12 weeks post-radiotherapy, 92% (22/24) of patients achieved OR, and 81% (17/21) obtained OR at 24 weeks post-radiotherapy. The median pain response time was 4 (3, 5) d. At the last follow-up, 42% (10/24) of patients maintained pain relief for over 1 year, with a median duration of pain relief up to 11.0 (6.0, 16.9) months. The 1-year OS rate was 66.3%, and no patients experienced grade 3 or higher acute or chronic adverse events.Conclusion:HFRT-SIB can effectively alleviate pain, and achieve sustained pain control, and does not lead to severe adverse effects in patients with non-osteogenic spinal metastases.
