Objective To investigate the effects of Xinnaoxuemianning combined with statins on carotid atherosclerotic plaque in patients with cerebral infarction. Methods 180 cerebral infarction patients were divided into the observation group (90cases) and the control group (90cases) by random number table method. The control group was given atorvastatin calcium tablets and the observation group was given additionally Xinnaoxuemianning. The changes and prognosis of carotid atherosclerotic plaques were evaluated before and after treatment, and the incidence of adverse reactions was counted. Results There were no differences in the carotid atherosclerotic plaque, TCM syndrome score and neurological deficit severity between the two groups before treatment. After treatment, the above indexes were significantly improved, and the increasing degree of the observation group was better than that of the control group. The incidence rate of adverse reactions was lower in the observation group than that in the control group (5.56％ vs.13.33％) (P<0.05). Conclusion Xinnaoxuemianning can reduce the carotid atherosclerotic plaque area and correct the unstable plaques in patients with cerebral infarction.

[Objective]To verify whether or not the modified open-door laminoplasy preserving semispinalis cervicis insert into axis is effective in preventing postoperative axial symptom and maintaining postoperative cervical sagittal alignment.[Method]Since March 2002 to December 2003,forty-eight patients underwent modified open-door laminoplasy preserving semispinalis cervicis insert into Axis,among them,thirty-two patients who were followed up for more than 2 years were included in this study.Preoperative and postoperative JOA score,degree of axial symptom,ranges of neck motion,cervical curvature index were recorded and compared.[Result]Preoperative and postoperative JOA score was(9.04?2.9)and(12.5?3.1)respectively,with recovery rate as(44.9?26.9).There was significant difference between preoperative evident axil symptom rate(46.8%)and postoperative evident axil symptom rate(18.7%),while no significant difference between preoperative and postoperative ranges of neck motion,cervical curvature index was seen.[Conclusion]Modified open-door laminoplasy is less invasive to the posterior extensor mechanism especially the semispinalis cervicis than conventional open-door laminoplasy.This new procedure is effective in preventing postoperative morbidities often seen after conventional laminoplasy with adequate decompression of the spinal cord.

BACKGROUND: After acute spinal cord injury (SCI), edema of spinal cord is an important factor for inducing and deteriorating pathological changes of spinal cord tissue. After injury, noradrenaline (NE) instantly causes microvascular contraction, endothelial injury, increase of arterial permeability and participation in edema. Recently, many researches suggest that excitatory amino acids (EAA) are related to cellular edema.OBJECTIVE: To study the effect and mechanism of selective phenol aminergic neuron, 6-hydroxy dopamine (6-OHNA)and aspartic acid (ASP) on edema after acute SCI.DESIGN: Randomized controlled study.SETTING: Department of Spine Surgery, the Third Hospital of Hebei Medical University.MATERIALS: The experiment was carried out at the Experimental Animal Center of the Third Hospital of Hebei Medical University from March to September 2003. A total of 160 Wistar rats weighing 300-350 g of both genders were randomly divided into three groups: 6-OHNA group (n =60), MK-801 group (n =50) and control group (n =50).METHODS: Acute SCI was induced at the level of T13 vertebral body with the static lcad technique. Rats in 6-OHNA group were injected with 6-OHNA into subarachnoid space; rats in MK-801 group were injected with MK-801 into caudal vein; rats in control group did not receive any treatment. The extent of edema was compared in the three groups by means of neurological scoring, water content measurement, light microscopy and electron microscopy.MAIN OUTCOME MEASURES: Neurological scores and water content.RESULTS: All 160 rats were involved in the final analysis. ① After SCl, content of NE in 6-OHNA group was decreased from (217.45±4.26) ng/g to (29.37±2.61) ng/g, and the difference was significant (P＜ 0.01). Edema in spinal cord tissue was effectively inhibited for 24 hours. At 12 hours after SCl, function recovered remarkably and vascular-derived edema was the mildest. ② In MK-801 group, there was no significant suppression of the edema until 24 hours after injury. Early recovery of neurological function was not significantly different from that in control group (P ＞ 0.05), but functional recovery was obvious until 24 hours after injury (P＜0.05). The degree of cytotoxic edema was the lightest.CONCLUSTON: NE can inhibit vascular-derived edema at early phase of SCI, and EAA can inhibit cytotoxic edemas,which develops at a relatively later stage.

Background and purpose:RASSF10 acts as a kind of tumor suppressor in various tumor tissues, but researches in cardiac adenocarcinoma has not been reported. This study aimed to detect the methylation status and expression ofRas-association domain family 10 (RASSF10) in gastric cardia adenocarcinoma (GCA), and explore its role in occurrence and development of GCA.Methods:Methylation speciifc polymerase chain reaction (MSP), reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry method were respectively used to detect methylation status, mRNA expression and protein expression ofRASSF10 in 81 GCA tissues and corresponding normal tissues.Results:The promoter methylation frequency ofRASSF10 in GCA tissues (64.20%, 52/81) was signiifcantly higher than that in corresponding normal tissues (20.99%, 17/81,P<0.05), and was closely correlated with TNM stages, differential degree and lymph node metastasis (P<0.05). RASSF10 mRNA expression in GCA tissues (0.57±0.05) was significantly lower than that in corresponding normal tissues (0.78±0.02,P<0.05), and was closely correlated with TNM stages and lymph node metastasis (P<0.05). Protein expression of RASSF10 in GCA tissues (31.10%, 26/81) was signiifcantly lower than that in corresponding normal tissues (71.60%, 58/81,P<0.05), and was closely correlated with TNM stages, differential degree and lymph node metastasis (P<0.05). The promoter methylation frequency ofRASSF10 in GCA tissues was inversely related to its protein expression.Conclusion:Inactivation of RASSF10 caused by aberrantmethylation in the promoter region may be closely correlated with the GCA tumorgenesis.

Aim To investigate the effects of quercetin and psoralen on the proliferation of human breast carcinoma cells in vitro.Methods Effects of quercetin and psoralen on the cell proliferation was tested in ER-positive MCF-7 cells by flow cytometer and Western blot.And the estrogen-like effect of psoralen and its relation with the estrogen-receptor were evaluated by pure estrogen receptor antagonist ICI182,780 as a tool.Results ① Psoralen(10 ?mol?L-1) and quercetin(10 ?mol?L-1) stimulated proliferation of MCF-7 cells compared with vehicle control,and the cell cycle was impulsed from G1 to S,DNA synthesizing was enhanced.It was also found the above function on boosting MCF-7 cell proliferation could be inhibited by adding estrogen receptor antagonism ICI182,780.② Psoralen(10 ?mol?L-1) and quercetin(10 ?mol?L-1) up-regulated ER? protein levels without altering ER? levels.The above up-regulation on ER? protein could be inhibited by adding estrogen receptor antagonism ICI182,780.Conclusions Psoralen and quercetin have the estrogen-like activities through the estrogen response pathway.And they exert estrogenic activity to MCF-7 cell proliferation through interaction with ER? expression.

Objective: To observe the clinical efficacy of acupuncture plus rehabilitation training in treating post-stroke deglutition disorders of qi-deficiency blood stasis pattern. Methods: Sixty-six patients with post-stroke deglutition disorders of qi-deficiency blood stasis patter were divided into an observation group and a rehabilitation group using the random number table method. The two groups both received conventional medications and supportive treatment for stroke. In addition, the observation group received acupuncture plus rehabilitation training while the rehabilitation group only received the same rehabilitation training. The interventions were conducted 3 times a week for a total of 4 weeks in both groups. They were evaluated using Kubota water swallowing test (KWST), Fujishima Ichiro food intake level scale (FILS) and symptoms score of traditional Chinese medicine (TCM) before and after treatment, and at the 1-month follow-up. The therapeutic efficacy was assessed at the 1-month follow-up. Results: The KWST grading and FILS result after treatment and at the follow-up were significantly different from those before treatment in both groups (all P<0.001); the results of these two items at the follow-up were not significantly different from those after treatment in the two groups (all P>0.05). There were significant differences in the KWST grading and FILS result between the two groups after treatment and at the follow-up (all P<0.05). The TCM symptoms score changed significantly after treatment and at the follow-up compared with that before treatment in both groups (all P<0.001). The TCM symptoms grading efficacy at the follow-up was significantly different from that after treatment in the observation group (P<0.05), while the difference was statistically insignificant in the rehabilitation group (P>0.05). The TCM symptoms grading efficacy in the observation group was significantly different from that in the rehabilitation group after treatment and at the follow-up (both P<0.05). Conclusion: Based on the conventional treatment for stroke, acupuncture plus rehabilitation training or use of rehabilitation training alone both can improve the clinical symptoms in post-stroke deglutition disorders of qi-deficiency blood stasis pattern, but acupuncture plus rehabilitation training can produce more significant efficacy and better long-term efficacy in improving TCM symptoms.
