ObjectiveTo investigate the effect of Naoxueshu oral liquid on cerebral hemorrhage caused by hypertension. Methods140 patients with cerebral hemorrhage were randomly dividied into two groups with a 1∶1 ratio,treatment group and control group. Patients in treatment group received Naoxueshu oral liquid 30 ml daily,while that in control received Naoxuekang oral liquid 30 ml daily. The changes of score on Chinese medical integration,National Institutes of Health (NIH) Stroke scale and the volume of intracranial hemorrhage were evaluated before and a month after treatment.ResultsThe decrease of NIH score of patients in treatment group was (12.73±3.94),but(4.72±3.01) with the control's (t=13.5327,P<0.001). The decrease of the volume of intracranial hemorrhage of patients in treatment group was (13.28±4.17) ml,but (8.37±7.24) ml with the control's(t=4.9228,P<0.001). ConclusionComparing with Naoxuekang,Naoxueshu can accelerate absorption of hematome and ameliorate the recovery of neurological disability more efficiently.

This study examined the potential antilithic effects of a traditional Chinese medicine Urtica dentata Hand (UDH) in experimental rats and screened the optimal extract of UDH as a possible therapeutic agent for kidney stones. The rat model of urinary calcium oxalate stones was induced by intragastric (i.g.) administration of 2 mL of 1.25% ethylene glycol (EG) and 1% ammonium chloride (AC) for 28 days and was confirmed by Color Doppler ultrasound imaging. The rats in different experimental groups were then intragastrically given petroleum ether extract (PEE), N-butanol extract (NBE), aqueous extract (AqE) of UDH, Jieshitong (positive control drug), and saline, respectively. Treatment with NBE significantly reduced the elevated levels of urinary calcium, uric acid, phosphate, as well as increased urinary output. Accordingly, the increased calcium, oxalate levels and the number of calcium oxalate crystals deposits were remarkably reverted in the renal tissue of NBE-treated rats. In addition, NBE also prevented the impairment of renal function to decrease the contents of blood urea nitrogen (BUN) and creatinine. Taken together, these data suggest that NBE of UDH has a beneficial effect on calcium oxalate urinary stones in rats by flushing the stones out and protecting renal function.

The aim of this study is to investigate the therapeutic effect of RegIII-proinsulin-pBudCE4.1 plasmid on streptozotocin (STZ)-induced type 1 diabetes mellitus and its underlying mechanisms. The model of type 1 diabetes mellitus was established by intraperitoneal injections of STZ (40 mg kg(-1)) to Balb/c mice for five consecutive days. Then, ten type 1 diabetic mice were intramuscularly injected with 100 microg RegIII-proinsulin-pBudCE4.1 plasmid for 4 weeks (one time/week) and the blood glucose levels were monitored every week; whereas another ten diabetic mice served as negative control group were injected with pBudCE4.1 vector at the same dose. Normal control and model control mice were treated with normal saline at identical volume under the same way. Western blotting, MTT assay, ELISA, HE staining and Tunel assay were applied to explore the underlying mechanisms. Results showed that RegIII-proinsulin-pBudCE4.1 plasmid ameliorated the hyperglycemia symptoms in diabetic mouse remarkably. It induced an immunological tolerance state in type 1 diabetic mice by inhibiting the proliferation of splenic lymphocytes and recovering Th1/Th2 balance evidenced by MTT and ELISA analysis. Furthermore, it elevated insulin concentration in the serum of type 1 diabetic mice and promoted the regeneration of beta cells supported by the results of HE staining and Tunel assay. In conclusion, RegIII-proinsulin-pBudCE4.1 plasmid possesses powerful anti-diabetic ability, which may be involved in the inducing of immunological tolerance and enhancing beta cells recovery.

OBJECTIVE: To explore the clinical evaluation system reflecting the superiority and characteristics of comprehensive traditional Chinese medicine (TCM) therapy for acute stroke. METHODS: A randomized controlled trial with single blind in various therapeutic centers was applied on the patients with the acute stage of hemorrhagic stroke due to hypertension, who were allocated to the trial group and the control group. The trial group accepted the general Western medicine therapy and differential treatment of traditional Chinese medicine based on stage classification. Patients in the control group were treated with the general Western medicine and the placebo of traditional Chinese herbal medicine. The treatment effect was assessed at the 7th day, 14th day, 21st day, and 28th day of post-treatment and after 3-month follow-up. The clinical evaluation system included the syndromes of TCM (ZH), Glasgow coma standard (GCS), nerve functional failure (NF), activity of daily living (ADL), Barther index (BI), quality of life index (QLI) and functional activities questionnaire (FAQ). RESULTS: Four hundred and four patients with acute stroke were included. There were 178 cases with yang-syndrome and 21 cases with yin-syndrome in the trial group (n=199), and there were 165 cases with yang-syndrome and 40 cases with yin-syndrome in the control group (n=205). The rates of recovery and obvious improvement after 3-month treatment in the trial group and the control group were 86.5% and 73.6% respectively. There was significant difference between the two groups (P<0.01). The response sensitivity of the effect items indicated that the sensitivity of GCS began to increase from the 7th day and was high at the 14th day and the 21st day for all patients. The response sensitivity of the NF scale was high for all patients at the 14th day, the 21st day and the 28th day. The BI scale and the QLI scale were sensitive to the patients with light and middle stage of stroke at the 21st day, and were sensitive to the patients with light stage of stroke after 3-month follow-up. The FAQ scale was sensitive to the light stroke at the 21st day and after 3-month follow-up. The ADL scale was sensitive to all patients at the 28th day and the patients with light stage of stroke after 3-month follow-up. The ZH scale was sensitive to all patients from 0 to 7d, the 14th day, and the 28th day. The principle components analysis indicated these 7 items could reflect the condition of stroke from 0-7d, the 21st day and after 3-month follow-up, and could be used to evaluate the therapeutic effect of hemorrhagic stroke. ZH scale and FAQ scale were more sensitive than other effect items at the 28th day. CONCLUSION: The seven items (GCSbNFbBIbQLIbFAQbADLbZH) have high sensibility to all patients in the acute stage of hemorrhage stroke especially at the 21st day. The ZH score will change in accord with the condition of stroke, and is appropriate to reflect the condition of stroke. It is believed that the seven items can form the system of effect evaluation in different stages of stroke, and the ZH scale is a very important item.

Objective To explore left ventricular remodeling index(LVRI),systolic function and their correlation by real-time three-dimensional echocardiography(RT-3DE)in patients with coronary artery disease(CAD).Methods According to coronary artery angiography,one main vessel stenosis no less than 50% was defined as positive standard,RT-3DE data of 24 patients with left circumflex coronary artery or/and right coronary artery stenosis(LCA/RCA group),21 patients with left anterior descending coronary artery stenosis(LAD group),27 patients with double or triplex coronary arteries stenosis which must included LAD(vessels group)and 22 normal controls(NC group)were acquired.Left ventricular end-diastolic volume(EDV),left ventricular end-diastolic epicardial volume(EDVepi),left ventricular ejection fraction(EF)were automatically measured by RT-3DE analysis software;left ventricular mass[1.05×(EDVepi-EDV)],LVRI(left ventricular mass/EDV)were calculated.The inter-group differences of LVRI,EF and intra-group correlations between LVRI and EF were analyzed.Results LVRI and EF significantly decreased in order(P＜0.05 or P＜0.01);and their correlation coefficents were r=0.10(P＞0.05),0.86(P＜0.01),0.83(P＜0.01)and 0.77(P＜0.01)in NC group,LCA/RCA group,LAD group,vessels group,respectively.Conclusions LVRI measured by RT-3DE can assess left ventricular remodeling,and reflect left ventricular systolic function in different CAD,which can be as a new approach for evaluating left ventricular remodeling in clinic.
