Objective To investigate the effects of pre-ischemic administration of L-NAME on brain protective effects of simvastatin against focal cerebral ischemic/reperfusion injury in rats. Methods ① Animals were subjected to transient 2-hour middle cerebral artery occlusion(MCAO)with the use of the intraluminal filament method previously described by Zea Longa. ② 54 male rats were treated with simvastatin or vehicle by gavage two weeks before MCAO, and L-NAME was injected into laterar ventricle of rats 45 minutes before MCAO. After neurological deficit was assessed at 22 hours of reperfusion, rats were killed, and the brains were rapidly removed. The coronal sections of the brains were prepared and stained with 2% TTC, and the infarct volumes were determined. Another 54 male rats were performed as description above except that the brain tissues were made into homogenate at 22 hours of reperfusion, and the contents of lactic acid(LA) and MDA, and the activities of superoxide dismutase(SOD) in the brain tissues were also measured. Results Administration of simvastatin significantly reduced the size of brain infarct, improved neurological deficits, decreased the contents of LA and MDA and increased the activities of SOD, but L-NAME could abrogate these effects. Conclutions L-NAME could abrogate the protection of simvastatin against ischemic/reperfusion injury,which may be by inhibiting the expression and activity of endothelial NO synthase(eNOS) up-regulated by simvastatin.

Objective: To investigate the effect of administrative HDL-C (high density lipoprotein cholesterol) level on adverse cardiovascular events after discharge in elder patients with ST-segment elevation myocardial infarction (STEMI).
Methods: A total of 325 STEMI patients treated in our hospital from 2010-04 to 2012-07 were retrospectively studied. According to administrative HDL-C level, the patients were divided into 2 groups as High HDL-C group, n=139 and Low HDL-C group, n=186. The basic and clinical conditions, in-hospital treatment, death and the medication, adverse cardiovascular events during 6 and 12 months follow-up period were compared between 2 groups.
Results: The patients with in-hospital reperfusion therapy was higher in Low HDL-C group, and Low HDL-C group had the higher ratio of emergent PCI treatment, all P<0.05. During follow-up period, High HDL-C group had less patients with β-receptor blocker treatment, less non- fatal MI, adverse cardiovascular events and re-hospitalization, all P<0.05. Cox regression analysis showed that low HDL-C level (HR=0.558, P=0.024) and diabetes mellitus (HR=1.528, P=0.040) were the risk factors of adverse cardiovascular events, while emergent PCI (HR=0.47, P=0.001) was the protective factor in STEMI patients after discharge.
Conclusion: The lower administrative HDL-C level in elder patients with STEMI had the higher risk of adverse cardiovascular events after discharge.

Objective:To make a preliminary application of the assessment system for cancer pain management and find insuffi-ciency in the clinical practice of cancer pain diagnosis and treatment. Methods:Data from 41 doctor questionnaires, 43 nurse question-naires, 50 patient questionnaires, and 12 ward questionnaires from the tumor departments of 3 hospitals were analyzed, and the insuffi-ciency in cancer pain management was determined. The wards in the tumor and non-tumor departments related to oncology were as-sessed using rank test, and differences between the 2 wards were investigated. Results:The average scores of doctor, nurse, and wards were 85.41±5.93, 88.46±5.09 and 83.75±3.11, respectively, whereas patient score was 68.67±7.14. To further analyze the patient subsys-tem by converting into a hundred-mark system, the effectiveness and safety scores for the pain management was 81.69±7.71. However, patients' opinion score on pain treatment was only 55.78±11.37. The score of tumor departments was 82.22±2.03, whereas related non-tumor departments had a score of 39.27 ± 3.58. Wilcoxon W value was at 120.0 with P<0.01 after rank test. Conclusion:Education on patients' opinion on cancer pain management should be promoted in the tumor wards, and continuous education on cancer pain diagno-sis and treatment is needed in the non-tumor departments relative to oncology.

OBJECTIVE:To observe clinical efficacy and safety of Kangfuxin liquid in the treatment of pediatric hand,foot and mouth disease. METHODS:128 children with hand,foot and mouth disease were randomly divided into observation group and control group,with 64 cases in each group. Control group was given routine treatment as herpes and oral care,antibiotics for infec-tive children reflected by hemogram elevation,fluid infusion and non-steroidal analgesic-antipyretic agent based on disease condi-tion. Observation group was additionally given Kangfuxin liquid,3 ml for below 3 year-old,tid and 5 ml for more than 3 year-old,tid. Clinical efficacy of 2 groups were observed as well as CRP,lactic acid,Ig,the level of myocardial enzyme before and after treatment;the time of symptoms and signs disappearance and ADR were compared between 2 groups after treatment. RE-SULTS:The total effective rate of observation group(89.06%)was significantly higher than that of control group(70.31%),with statistical significance(P<0.05). There was no statistical significance in CRP,lactic acid,Ig and myocardial enzyme before treat-ment and IgM level after treatment between 2 groups,with statistical significance(P>0.05). CRP,lactic acid creatine kinase and lactate dehydrogenase level of 2 groups decreased significantly,while IgA and IgG levels increased significantly,and the observa-tion group was higher than the control group,with statistical significance(P<0.05). Antipyretic time,hand foot skin rash subsided time and oral ulcer healing time of observation group were significantly shorter than those of control group,with statistical signifi-cance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Kangfuxin liquid is effective in the treatment of hand,foot and mouth disease in children,and can effectively improve CRP,Ig,lactic acid,and myocardial enzyme level with good safety.

The inflammatory reaction after acute cerebral infarction can aggravate the cerebral ischemic reperfusion injury.Activation of peroxisome proliferator-activated receptors-γ(PPAR-γ) has neuroprotective effects by which induces anti-inflammatory actions in cerebral ischaemia,thus as a potential novel pharmacological target for ischemic stroke was regarded.Acupuncture can improve cerebral ischemia injury by inhibiting synthesis of inflammatory cytokines,downregulating expressions of inflammatory mediators and adhesion molecule,suppressing the functions of inflammatory cells.Therefore,it will be a promising orientation to sift the effective acupuncture for that can stimulate the activation of PPAR-γ,and the research of mechanism of acupuncture on anti-inflammatory reaction after cerebral ischemic by activating PPAR-γ dependent pathways.

OBJECTIVETo discuss the relative association of soft tissue tension and cervical physiological curvature chang in patients with scapula muscle fasciitis.

METHODSFrom February 2012 to December 2012,29 patients with scapula muscle fasciitis were investigated. There were 10 males and 19 females with an average age of 27.77 years old (ranged from 22 to 40 years old). Routine AP and lateral cervical X-rays were done in all patients. Cervical lordosis was measured according to Borden's method and the pain point tension was measured by soft tissue tension meter. Finally,perform statistic analysis to bove data.

RESULTSLateral X-rays showed 9 cases were normal cervical lordosis, 18 cases were cervical lordosis decreased, 2 cases were cervical lordosis increased. The regression equation of cerical lordosis changes D(Y) and soft tissue tension displacement D0.5 kg (X) was Y = -15.069 + 3.673X.

CONCLUSIONThere is linear relationship between soft tissue tension and cervical physiological curvature change. With the soft tissue tension increases, the cervical lordosis trend to decrease.
