OBJECTIVE: To study the influence of Jieyu Huoxue Decoction on rehabilitation of patients with depression after cerebral infarction. METHODS: Fifty four patients suffered from the depression after acute cerebral infarction were randomly divided into three groups: depression control group, fluoxetine treated group and Jieyu Huoxue Decoction treated group. Eighteen patients of cerebral infarction without depression were enrolled in the no depression control group randomly. The Zung self-rating depression scale (SDS), the modified Edinburgh-Scandinavia stroke scale (MESSS) and the activities of daily living (ADL) were evaluated before treatment, 30 and 60 days after treatment. RESULTS: After 30 and 60 days of treatment, SDS evaluation of the Jieyu Huoxue Decoction treated group showed significant difference as compared with the condition before treatment and that of the depression control group (P < 0.05 or P < 0.01), MESSS evaluation and ADL evaluation also showed significant difference as compared with the condition before treatment and that of the depression control group (P < 0.05 or P < 0.01); there was no obvious difference between the fluoxetine treated group and the Jieyu Huoxue Decoction treated group, but the Jieyu Huoxue Decoction treated group showed fewer symptoms and less side effect. CONCLUSION: Jieyu Huoxue Decoction can not only relieve depression after cerebral infarction, but also improve neurological functions.

Objective To explore the influence of the sequential enteral nutrition(SEN) on nutritional status and prognosis in patients with acute cerebral infarction(ACI).Methods 80 ACI patients complicated with dysphagia were divided into SEN group and control group(40 cases in each group).In the first three days patients in SEN group were treated with nasal feeding short-peptide enteral nutrition[84~126(kJ/kg.d) ],than,which would be replaced with nasal feeding integral-protein enteral nutrition from the forth day.Patients in the control group were provided with ordinary fluid food by nasal feeding.Nutrition support for both groups was at last more than 10 d.In the 1 d,7 d and 14 d after treatment,data of both groups concerned with triceps skin fold(TSF),mean upper arm muscle circumference of triceps(MAMC),serum albumen(Alb),serum prealbum(PAB),heamoglobin(Hb),incidence of infectious complications,National Institutes of Health Stroke Scale(NIHSS) score and Barthel index(BI) were examined.Results Nutritional indexes(TSF,MAMC,Alb,PAB,Hb) in the SEN group were significantly higher than those in the control group(P

Objective To investigate the clinical effect of resuscitating acupuncture and scalp acupuncture on neurological function and high sensitivity C reactive protein (hs-CRP) in serum in patients with acute cerebral infarction. Methods 90 patients with acute cerebral infarction were divided into three groups: drug, routine acupuncture and resuscitating acupuncture and scalp acupuncture groups in random. They were evaluated with NIH Stroke Scale (NIHSS) , Modified Rankin Scale (MRS) 0, 7, 14 d after treatment, and measured with the levels of hs-CRP. Results There were significant improvements for NIHSS and MRS scores in the resuscitating acupuncture and scalp acupuncture group compared with those of the others, as well as the levels of hs-CRP. Conclusion Resuscitating acupuncture and scalp acupuncture can reduce the level of hs-CRP and improve the neurological functions in patients with acute cerebral infarction.

Objective To investigate the protective effects of Dextran-40 on fatal jellyfish stings at whole animal and cellular levels.MethodsFirstly, using the fatal jellyfish envenomation syndrome (acute jellyfish envenomation syndrome, AJES and delayed jellyfish envenomation syndrome, DJES) models established earlier by ourselves, we surveyed the effects of Dextran-40 on the survival rate of AJES mice, on the circulatory function of AJES rats and on the serum biochemical indexes of DJES rats.In addition, the protective effects of Dextran-40 on cardiomyocytes against the damage induced by tentacle extract (TE) from the jellyfish Cyanea capillata were studied at the cellular level by laser scanning confocal microscopy.ResultsAt the whole animal level, Dextran-40 at 0.8g/kg significantly improved the survival rate of AJES mice, and at 0.6g/kg greatly inhibited the drop of blood pressure of AJES rats.For the DJES rats, Dextran-40 at 0.6g/kg had a significant protective effect on the liver function indexes (ALT, AST, A/G) and myocardial enzymes (CK, LDH).At the cellular level, Dextran-40 5μg/mL greatly inhibited the TE-induced increase in intracellular Ca2+ content and the death of cardiomyocytes.ConclusionThe protective effects of Dextran-40 on fatal jellyfish stings may be related to its ability to stabilize blood pressure or block the TE-induced pore formation in the cardiomyocytes.Considering that the clinical safety of Dextran-40, we strongly recommend it as a first-aid medicine for jellyfish stings.

Ibuprofen/ethyl-cellulose (EC)-polyvinylpyrrolidone (PVP) sustained-release composite particles were prepared by using supercritical CO2 anti-solvent technology. With drug loading as the main evaluation index, orthogonal experimental design was used to optimize the preparation process of EC-PVP/ibuprofen composite particles. The experiments such as encapsulation efficiency, particle size distribution, electron microscope analysis, infrared spectrum (IR), differential scanning calorimetry (DSC) and in vitro dissolution were used to analyze the optimal process combination. The orthogonal experimental optimization process conditions were set as follows: crystallization temperature 40 degrees C, crystallization pressure 12 MPa, PVP concentration 4 mgmL(-1), and CO2 velocity 3.5 Lmin(-1). Under the optimal conditions, the drug loading and encapsulation efficiency of ibuprofen/EC-PVP composite particles were 12.14% and 52.21%, and the average particle size of the particles was 27.621 microm. IR and DSC analysis showed that PVP might complex with EC. The experiments of in vitro dissolution showed that ibuprofen/EC-PVP composite particles had good sustained-release effect. Experiment results showed that, ibuprofen/EC-PVP sustained-release composite particles can be prepared by supercritical CO2 anti-solvent technology.
