Objective To explore expression of plexinA1 and Ki-67 in tissue of human brain glioma cells and their clinical significance.Methods 43 specimens from patients with brain glioma were collected.Immunohistochemical (IHC) staining was used for detecting the expression of tissue plexinA1 and Ki-67 in human glioma cells of 43 cases of patients with brain glioma.The positive expression rate of plexinA1 and Ki-67 among the different pathological grade tissues and their clinical significance were analyzed.So did correlation studies about plexinA1 and Ki-67.Results The positive expression rates of plexinA1 in Ⅰ-Ⅱ grade group (18 cases) and Ⅲ-Ⅳ grade group (25 cases) were 22.22 % (4/18) and 72.00 % (18/25) (P < 0.05).The positive expression rates of Ki-67 in Ⅰ-Ⅱ grade group and Ⅲ-Ⅳ grade group were 16.67 % (3/18) and 56.00 % (14/25),respectively (P < 0.05).PlxinA1 and Ki-67 expression in the tissue of human brain glioma were positively correlated (r =0.997,P < 0.05).Conclusions The positive expression rate of plexinA1 is higher in high malignancy human glioma group than that in low malignancy group which has an important reference value in the estimation of prognosis for human glioma.PlexinA1 and Ki-67 maybe synergism in occurrence and development of glioma.

Objective:To assess the clinical efficacy of abdominal acupuncture for subhealth insomnia.Methods:Eighty-two cases of subhealth insomnia were randomly divided into an observation group (41 cases) and a control group (41 cases).The control group was treated with conventional acupuncture.The observation group was treated with Bo's abdominal acupuncture on the basis of conventional acupuncture.Six treatments constituted one treatment course.The measuring scale of traditional Chinese medicine syndrome for subhealth state (MSSSHS) and Pittsburgh sleep quality index (PSQI) scores were compared between the two groups after two courses,to estimate the efficacy of abdominal acupuncture for subhealth insomnia.Results:One case dropped out from the observation group,while 2 cases dropped out from the control group.The MSSSHS score and PSQI score both declined after the treatment in the two groups (all P<0.05).The MSSSHS and PSQI scores in the observation group were significantly lower than those in the control group (both P<0.05).Conclusion:The abdominal acupuncture is effective for subhealth insomnia,and it can enhance the effect of conventional acupuncture.

After 28 foreign species of AM fungi were inoculated in sterilized soil, the effects of the AM mycorrhizal colonization and the medicine quality of Paris polyphylla var. yunnanensis were observed by combination of inoculation test in pot at room temperature and instrumental analysis. The results showed that, compared with control group (CK), the inoculation of foreign AM fungi in the soil influenced the spore density, mycorrhizal infection rate, and colonization intensity of AM fungi in root system of P. polyphylla var. yunnanensis. The inoculation of foreign AM fungi enhanced the mycorrhiza viability of P. polyphylla var. yunnanensis by increasing the activity of succinic dehydrogenase (SDH) and alkaline phosphatase (ALP) in intraradical hyphae. The content of single steroid saponin in rhizome of P. polyphylla var. yunnanensis showed variation after P. polyphylla var. yunnanensis was inoculated by different foreign species of AM fungi, which was beneficial for increasing the medicine quality; however, the kinds of steroid saponin showed no difference. In a degree, there was a selectivity of symbiosis between P. polyphylla var. yunnanensis and foreign AM fungi. And we found that the Claroideoglomus claroideum and Racocetra coralloidea were best foreign AM fungi species for cultivating P. polyphylla var. yunnanensis under field condition.

OBJECTIVETo investigate the changes of the mRNA expressions of myocardial cytoskeletal proteins in endotoxemic rats.
METHODSThirty-seven Wistar rats were randomized into two groups with injection of 10 mg/kg lipopolysaccharide (LPS) or normal saline through the femoral vein. The cardiac function of the rats was monitored continuously for 24 h, and the morphological changes of the cardiac myocytes were observed with HE staining and electron microscope. The mRNA levels of myocardial cytoskeletal proteins including actin, tubulin and desmin were determined by RT-PCR.
RESULTSNo significant difference was found in the number of CD3(+)T lymphocytes in the TILs between different groups. After the immunotherapy, the peLPS injection resulted in significant impairment of the cardiac function and myocardial microstructure of the rats with reduced heart rate and left ventricular systolic pressure (LVSP). The mRNA expression of actin in the cardiac myocytes measured by fluorescence optical density was reduced significantly 8 h after LPS injection, and that of tubulin was decreased significantly 24 h after LPS treatment; desmin mRNA expression showed no significant variation after LPS injection.
CONCLUSIONLPS can significantly impair the cardiac function of the rats possibly by inducing damages of the myocardial cytoarchitecture and causing changes in the mRNA expressions of such cytoskeletal proteins as actin and tubulin.

Objective To evaluate the effects of sevoflurane on the expression of heparanase ( HPA) and fascin in lung carcinoma cells of mice. Methods Mouse LLC cells were inoculated in the culture plate. After being cultured for 24 h, the cells were equally and randomly divided into 4 groups using a random number table: control group ( group CC) , 1% sevoflurane group ( group Sev1 ) , 2% sevoflurane group ( group Sev2 ) , and 3% sevoflurane group ( group Sev3 ) . Cells in Sev1-3 groups were exposed to 1%, 2% and 3% sevoflurane, respectively, for 4 h, while cells in group CC were not exposed to sevoflurane, and all the cells were then cultured for another 24 h in an incubator. The invasion of cells was determined by Transwell invasion assay, and the invaded cells were counted. The migration of cells was determined by wound healing assay, and cell migration rates were calculated. The expression of HPA and fascin in cells was detected by Western blot. Results Compared with group CC, the number of invaded cells and cell migration rates were gradually decreased, and the expression of HPA and fascin was gradually down?regulated with increasing concentrations of sevoflurane in Sev1-3 groups. Conclusion The mechanism through which sevoflurane inhibits the metastasis of mouse lung carcinoma cells is associated with down?regulated expression of HPA and fascin.

Objective: To access the risk for smoking on morbidity of acute ST-segment elevation myocardial infarction (STEMI) at different gender and age population. Methods: A case-control study was conducted in 2026 STEMI patients and 2026 control subjects with matched gender and age (±2 years) in our hospital from 2010-01-14 to 2016-02-27. The relationship between smoking and STEMI morbidity was analyzed. Results: Smoking was an important risk factor for STEMI morbidity in male gender and it was negatively related to age, as STEMI in young male smokers (≤45 years): adjusted OR=7.000, 95% CI 4.235-11.570; in middle age male smokers (46-59 years):adjusted OR=5.296, 95% CI 3.904-7.185 and in elder male smokers (≥60 years): adjusted OR=4.686, 95% CI 2.860-4.751. Conclusion: Smoking is a major risk factor for STEMI morbidity, while it is different from age and gender; the young male smokers have the highest risk to suffer from STEMI.
