Chinese Traditional and Herbal Drugs 1994;0(03):-
Effects of "Xuetangping", a herbal prescription composed of Radix Astragali, Radix Trichosanthis, Rhizoma Dioscoreae, Fructus Corni, and Radix Salviae Miltiorrizae, on serum sugar of mice or rats with diabetes mellitus induced by alloxan were studied. The result showed that "Xuetangping" (2.5g/kg, ig qd 7d or 14d ) lowered serum sugar in diabetic mice but not in normal mice.Xuetangpinec 1.5g/kg,ig qd 7d or 14d in diabetic in a dose and time dependent manner. While 14d, "Xuetangping" also decreased the value of serum lipid and the content of serum lipid peroxide. This result suggest that antiperoxide activity of this Chinese herbal formulation may be related to its reduction in serum sugar

ObjectiveTo explore the effect of home visit based on empowerment education on psychotic symptoms, self-management ability and well-being of schizophrenia patients in home rehabilitation. MethodsA total of 87 cases of schizophrenia patients who met the diagnostic criteria of International Classification of Diseases, tenth edition (ICD-10) and were recovering at home in Caiba town, Yibin city from January to July 2021 were selected by random sampling method as research subjects. They were divided into experimental group (n=43) and control group (n=44) according to the random number table method. The two groups received routine family visits, and the experimental group received family visits based on empowerment education. The intervention cycle of the two groups was 6 months. Before and after the intervention, the severity of psychotic symptoms, self-management ability and well-being of the patients in the two groups were assessed with the Brief Psychiatric Rating Scale (BPRS), the Schizophrenia Self-Management Instrument Scale (SSMIS) and the Index of Well-Being Scale (IWB). ResultsAfter intervention, the intra group comparison showed that the BPRS score in the experimental group was lower than that before the intervention (t=4.550, P<0.01), the SSMIS scores in both groups were higher than those before intervention (t=-17.107, -6.367, P<0.01), and the IWB score in the experimental group was higher than that before intervention (t=-9.239, P<0.01). The comparison between groups showed that the BPRS score of the experimental group was lower than that of the control group, and the SSMIS and IWB scores were higher than those of the control group (t=-3.899, 10.564, 9.690, P<0.01). ConclusionThe implementation of family visit based on empowerment education may help to improve the psychotic symptoms of home rehabilitation schizophrenia, and improve their self-management ability and well-being.

Objective To investigate the safety and efficacy of low-dose recombinant tissue plasminogen activator (rtPA) in Chinese patients with acute ischemic stroke. Methods Consecutive patients with acute ischemic stroke received rtPA intravenous thrombolysis within 4. 5 h after symptom onset were enrol ed retrospectively. According to the dosage of rtPA, they were divided into either a low-dose group (0. 5-0. 8 mg/kg, the maximum dose 50 mg) or a standard dose group (0. 9 mg/kg, the maximum dose 90 mg). The incidences of symptomatic intracranial hemorrhage ( sICH) ( the National Institute of Neurological Disorders and Stroke [NINDS], and European Cooperative Acute Stroke Study Ⅱ [ECASSⅡ] , European Safe Implementation of Thrombolysis in Stroke-Monitoring Study [ SITS-MOST ] ), 90 d mortality, 90 d good outcome (the modified Rankin Scale [mRS] score 0-1), and life self-care ability (mRS score 0-2) were compared between the two groups. Results A total of 163 patients were enrol ed, including 74 patients in the low-dose group and 89 in the standard dose group. The constituent ratios of hypertension (44. 6% vs. 68. 5%; χ2 =9. 490, P=0. 002) and diabetes (5. 4% vs. 28. 1%; χ2 =14. 216, P<0. 001) in the patients of the low-dose group were significantly lower than those of the standard group, while the constituent ratios of smoking (56. 8% vs. 38. 2%; χ2 =5. 590, P=0. 018 ) and smal artery occlusive stroke (21. 6% vs. 10. 1%; χ2 =4. 122, P=0. 042 ) in patients of the low-dose group were significantly higher than those of the standard group. After adjusting for age, National Institutes of Health Stroke Scale (NIHSS) score, hypertension, diabetes, smoking, and ischemic stroke typing, multivariate binary logistic analysis showed that there were no significant differences in NINDS defined sICH (10. 8% vs. 9. 0%, odds ratio [OR] 1. 077, 95%confidence interval [CI] 0. 338-3. 436), ECASS Ⅱdefined sICH ( 9. 5% vs. 9. 0%; OR 0. 976, 95% CI 0. 296- 3. 221 ), SITS-MOST defined sICH (8. 1% vs. 4. 5%; OR 2. 269, 95% CI 0. 522-9. 852), 90 d mortality (17. 6% vs. 14. 6%; OR 1. 720, 95% CI 0. 578-5. 119), 90 d good outcome (35. 1% vs. 32. 6%;OR 0. 780, 95% CI 0. 356-1. 709), and life self-care ability (48. 6% vs. 42. 7%;OR 0. 936, 95% CI 0. 441-1. 987) between the 2 groups (al P>0. 05). Conclusions The program of intravenous thrombolysis for the treatment of Chinese patients with acute ischemic stroke with low-dose rtPA is safe and effective.
