Objective To explore the effect of the method of cooling blood and removing stasis on promoting the relief of swelling and pain symptoms and the recovery of joint mobility in the early stage of acute ankle sprains.Methods From January 2023 to January 2024,a total of 88 patients with early-stage acute ankle sprains admitted to the Eighth Clinical Medical School of Guangzhou University of Chinese Medicine(Foshan Hospital of Traditional Chinese Medicine)were selected.The patients were randomly divided into an observation group and a control group using a random allocation method(random number table),with 44 patients in each group.The control group was treated following the PRICE principle for acute sports injury,with the measures such as ice compress,immobilization,and compression.The observation group,in addition to receiving the same treatment as the control group,was given the decoction of Liangxue Quyu Prescription orally(a formula with the actions of cooling blood and removing stasis,and composed of Ilicis Pubescentis Radix,Paeoniae Radix Rubra,Moutan Cortex,Rehmanniae Radix,Achyranthis Bidentatae Radix,Jujubae Fructus,and Glycyrrhizae Radix et Rhizoma),and external washing with Shujin Xi External Washing Granules(mainly composed of Clematidis Radix et Rhizoma,Sappan Lignum,Artemisiae Anomalae Herba,Uncariae Ramulus cum Uncis,and Glechomae Herba,and others.The treatment period for both groups lasted for one week.Before and after treatment,the changes in Visual Analogue Scale(VAS)scores of pain,ankle swelling scores,ankle range of motion(including plantar flexion and dorsiflexion),and the American Orthopedic Foot&Ankle Society(AOFAS)ankle-hindfoot scale scores in the two groups were observed.After treatment,the clinical efficacy of the two groups was evaluated.Results(1)After one week of treatment,the total effective rate in the observation group was 95.45%(42/44),and that in the control group was 86.36%(38/44).The intergroup comparison by chi-square test showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the VAS scores for pain in both groups were significantly reduced(P＜0.05)and the AOFAS scores for ankle function were significantly increased(P＜0.05)compared to those before treatment.The observation group showed significant reduction in VAS scores and obvious improvement in AOFAS scores compared to the control group(P＜0.05 or P＜0.01).(3)After treatment,the ankle swelling scores in both groups were significantly reduced(P＜0.05)and the ankle range of motion was significantly improved(P＜0.05)compared to those before treatment.The observation group showed significant reduction in ankle swelling scores and obvious improvement in the range of motion compared to the control group(P＜0.05 or P＜0.01).(4)After treatment,the scores for TCM symptoms of pain,ecchymosis and swelling,and scores of functional disorders in both groups were significantly reduced(P＜0.05)compared to those before treatment.The observation group showed significant reduction in pain,ecchymosis,and swelling scores compared to the control group(P＜0.01),while there was no significant difference in dysfunction scores between the two groups after treatment(P＞0.05).Conclusion The method of cooling blood and removing stasis has significant effects on improving swelling and pain symptoms during the early treatment of acute ankle sprains.It is effective on relieving swelling and pain,and is helpful for promoting the recovery of ankle joint function.

Impulsive-compulsive behaviors (ICBs), one of the non-motor symptoms of Parkinson′s disease (PD), may be attributed to dopaminergic dysfunction and dopamine replacement therapy. At present, understanding of ICBs, mechanisms and exploration of treatment largely depend on neuroimaging research. Despite contradictions among the findings, most evidence indicated that PD patients with ICBs showed decreased thickness in frontal and temporal cortex and the volume of subcortical nuclei when compared to those without ICBs. And the occurrence of ICBs is associated with relatively preserved white-matter integrity in the brain regions involved in reward-related behaviors. This article will give an overview of the magnetic resonance research of PD related ICBs including cortical thickness, diffusion tensor imaging, resting state and task state functional magnetic resonance imaging analysis, which lays a foundation for further imaging studies, revealing the pathogenesis and exploring the potential treatment options.

Objective:To evaluate the clinical effect and safety of Qufeng-Zhike prescription in the adjuvant treatment of cough variant asthma (CVA) with severe wind and acute narrow airway syndrome. Methods:A total of 82 patients with CVA with severe Wind and acute narrow airway syndrome, meeting the inclusion criteria in the hospital, were divided into control group and observation group by random number table method between September 2018 and September 2020, with 41 in each group. The control group was treated with budesonide formoterol dry powder inhalation, while the observation group was treated Qufeng-Zhike prescription on basis of control group. Both were treated for 8 weeks. Before and after treatment, scores of TCM symptoms was recorded. The forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and peak expiratory flow (PEF) were detected by spirometer. The peripheral blood eosinophil (EOS) count was detected by full-automatic blood cell analyzer. The level of fractional exhaled nitric oxide (FeNO) was detected by expiration analyzer. The quality of life was evaluated by Leicester cough questionnaire (LCQ). The adverse events were recorded, and clinical curative effect was evaluated. Results:The differences in total response rate of TCM syndromes between observation group and control group was statistically significant [97.6% (40/41) vs. 82.9% (34/41); χ2=4.986, P=0.026]. At 1, 2 and 8 weeks after treatment, scores of TCM syndromes in observation group were significantly lower than those in the control group ( t=2.104, 5.329, 3.527, P<0.05 or P<0.01). After treatment, FEV1 (2.78 ± 0.41 L vs. 2.56 ± 0.37 L, t=2.551), FVC (3.55 ± 0.50 L vs. 3.24 ± 0.44 L, t=2.980) and PEF (357.58 ± 70.98 L/min vs. 316.30 ± 75.60 L/min, t=2.549) in observation group were significantly higher than those in the control group ( P<0.05), while peripheral blood EOS count [(0.26 ± 0.07)×10 9/L vs. (0.30 ± 0.09)×10 9/L, t=2.246], FeNO level (22.55 ± 7.83 μg/L vs. 28.87 ± 9.36 μg/L, t=3.316) and LCQ score (5.62 ± 1.71 vs. 7.04 ± 2.28, t=3.190) were significantly lower than those in the control group ( P<0.05). During treatment, there were no obvious adverse events (liver and kidney function damage) in either group. Conclusion:The adjuvant treatment with Qufeng-Zhike prescription can help to alleviate allergic reactions, improve clinical symptoms, lung function and quality of life in patients of CVA with severe wind and acute narrow airway syndrome.
