RESUMEN

BACKGROUND: The initiation of exercise during rehabilitation at the subacute stage could provide stroke survivors with an approach to recovery that capitalizes on unique physiological conditions and promotes spontaneous recovery. We aimed to examine the effects of a tailored sitting Tai Chi program on recovery outcomes among subacute stroke survivors. METHODS: We conducted a 12-week assessor-blind randomized controlled trial in China. Subacute stroke survivor-caregiver dyads were recruited and randomly assigned to either the sitting Tai Chi group (n=80) or attention control group (n=80). Outcomes including upper limb function (Fugl-Meyer Assessment Upper Extremity & Wolf Motor Function Test), balance control (Berg Balance Scale), sitting balance control (Trunk Impairment Scale), depressive symptoms (Geriatric Depression Scale Short Form), shoulder range of motion, shoulder pain (ShoulderQ), activities of daily living (Modified Barthel Index), and quality of life (Stroke Specific Quality of Life Scale) were measured at baseline, in-process, immediately post, and 4-week postintervention. RESULTS: Immediately postintervention, the sitting Tai Chi group (n=69) showed significant upper limb function improvement in the primary outcomes including the performance time (regression coefficient of the group-by-time interaction, B=-21.415 [95% CI, -31.000 to -11.831]) and functional ability (B=10.146 [95% CI, 4.886-15.406]) domains of the Wolf Motor Function Test, balance control (B, 4.972 [95% CI, 1.356-8.588]), and sitting balance control (B=4.397 [95% CI, 2.699-6.096]). Compared with the control group (n=65), improvements were also observed in secondary outcomes including depressive symptoms (B=-1.626 [95% CI, -2.304 to -0.948]), shoulder extension (B=4.518 [95% CI, 0.893-8.144]), activities of daily living (B=5.510 [95% CI, 0.450-10.569]), and quality of life (B=15.680 [95% CI, 7.255-24.105]). CONCLUSIONS: The results support the effectiveness of a tailored sitting Tai Chi program in improving recovery outcomes among subacute stroke survivors and provide additional knowledge to support the clinical implementation of such a program.

RESUMEN

BACKGROUND: The Trunk Impairment Scale (TIS) has been translated into Chinese, but the psychometric properties of the Chinese version of the TIS (TIS-C) have not yet been established. We aimed to examine the reliability and validity of the TIS-C for assessing sitting balance among Chinese people with a stroke. METHODS: A descriptive, cross-sectional design was used. We recruited a convenience sample of 170 subacute stroke patients aged 18 years or over from the neurology departments of four traditional Chinese medicine hospitals in China. Patients completed the TIS-C, the Berg Balance Scale and the Modified Barthel Index. The psychometric properties of the TIS-C were examined to establish test-retest reliability, internal consistency, equivalence, and content, criterion, and construct validity. RESULTS: Intraclass correlation coefficients for inter-rater and intra-rater reliability ranged from 0.75 to 0.89 and from 0.90 to 0.97, respectively. The TIS-C Cronbach α was 0.86. The strong correlation between the total score of the TIS-C and the Berg Balance Scale (rs = 0.81, p < 0.001) or Modified Barthel Index (rs = 0.84, p < 0.001) suggested good concurrent and convergent validity, respectively. Known-group validity was supported by the significant difference (p < 0.001) in TIS-C scores between participants with mild and moderate stroke. CONCLUSIONS: The TIS-C is a valid and reliable tool for assessing static and dynamic sitting balance as well as coordination of trunk movement among stroke survivors with mild and moderate stroke.

RESUMEN

Pterocypsela is a very important traditional Chinese medicine from the tribe Cichorieae of Asteraceae. Mitotic chromosome numbers and karyotypes are reported for P. formosana and P. elata from Hunan and Hubei province, China. The former is new and the latter provide confirmation of previous reference. All P. taxa are diploidy with 2n = 18 and their basic number is tentatively suggested as x = 9. Karyotype of Pterocypsela is 2A and P. formosana with a karyotype formula of 2n = 2x = 18 = 4m + 14sm, and 2n = 2x = 18 = 2m + 8sm +8st for P. elata. It is the first time to report the AI value for Pterocypsela in this paper. Cytological data of chromosomal numbers and karyotypes were used to discuss the close relationships of the Pterocypsela genus and the taxonomy of the medicinal plants.

RESUMEN

OBJECTIVE: To study the aqueous two-phase system which could be used for extraction of berberine hydrochloride. METHODS: Three aqueous two-phase systems were used for extraction experiment firstly, the best one was chosen from that, and then the single factor experiment and orthogonal experiment were carried out. RESULTS: 10 mL 95% ethanol with 10 mL 2.2 mol/L ammonium sulfate could make a aqueous two-phase system, added 600 mg berberine hydrochloride whose purity was 53.22% into it, regulated its pH to 4, then the system was put into water-bath heater (70 degrees C) for 30 min, the extraction rate could reach 99.29%; Collected the extraction liquid, dried it under 40 degrees C, the purity of berberine hydrochloride was 88.43%. CONCLUSION: This system is a suitable aqueous two-phase system for extraction of berberine hydrochloride.
