This system is designed to effectively grease stacin,moisture and particde in the com- pressed air through various fictering mater als.In the same machine,it can finish a series of proce- dures such as washing,drying,filling and sealing the ampoules.It not only shorten the production process,reduce contamination links,but also increase the end product rates by 10% whereas de- crease the ampoule loss rates by over 5%.Simple,safe and reliable,it saves time,labour and elec- tric energy.

There is increasing consumption of exotic food in Malaysia. Animals such as insects, worms and wild life animals also form part of the staple food of the local population. This practice may lead to more incidence of food allergy and anaphylaxis. We report a non-indigenous man who developed food anaphylaxis after consuming fried sago worms and consequently Takotsubo cardiomyopathy. We postulate that certain food allergy and anaphylaxis could be another causative trigger for Takotsubo cardiomyopathy.

Objective To explore the causes of death of patients with cerebral hemorrhage of hypertension in recent 6 years and the countermeasure of decrease death rate.Methods The clinical data,different kinds of treatment and curative effects of the patients of two groups,admitted in recent six years,with cerebral hemorrhage of hypertension was refrospectively analysied.Results Of 157 cases of cerebral hemorrhage of hypertension in group A,there were 69 cases died(44%).Of 158 cases of cerebral hemorrhage of hypertension in group B,there were 48 cases died(30.4%).Death rate between the two of group had significant difference(P

Objective To investigate the protective effects and molecular mechanism of peroxisome proliferate-activated receptor α(PPARα) activation on acute myocardial damage induced by isoproterenol (Iso) in rats. Methods Thirty male Wistar rats, weighting 160～180 g, were randomly divided into control group, Iso group, fenafibrate(FF) group(each n=10) according to physique quantity. Acute myocardial injury caused by Iso abdomen cavity injection induced ischemia was established and the protective effects of peroxisome proliferate-activated receptor α activation were accessed by the level of ereatine kinase(CK), lactic dehydrogenase(LDH) in serum as well as the activities of myoperoxidase(MPO) in myocardium, and the protein expressions of PPABα in myocardium by Western blot. Results The level of serum CK in control group, lso group and FF group, was (62.41±9.47),(101.71±11.05),(75.64±11.73)kU/L, respectively(F= 34.34, P<0.01). Whereas the level of serum CK in Iso group and FF group was higher than that in control group(P<0.01 or<0.05), the level of serum CK in FF group was lower than that in Iso group(P<0.01). The levels of LDH in these three groups were (5912.20±204.44), (6365.78±137.10), (6089.76±169.60) U/L, respectively(F= 17.54, P<0.01). Compared with the control group, the levels of LDH in Iso and Fir groups were significantly increased(P<0.01 or<0.05). But the level of LDH in FIr group was decreased compared with that in Iso group(P<0.01). The activities of myocardial MPO in these three groups were (1.95±0.10),(3.89±0.17),(2.49±0.19)U/g, espectively(F=391.68,P< 0.01). The activities of myocardial MPO in Iso and FF groups were higher than that in the control group (all P< 0.01), while the activities of myocardial MPO in FIr group were lower than that in lso group(P<0.01). The protein expressions of PPARα in myocardium of these three groups were 251.57±10.95,191.97±10.74,215.08±9.61, respectively(F=82.69, P<0.01). Conclusion PPARα activation by its actor FF can exert protective effects on the acute myocardial ischemia injury induced by lso in rats through inhibiting the release of inflammatory cell factors.

Coptis chinensis is widely used as Chinese medicine herbs and serious soil problems occur after continual cultivation of this medicinal plant. In the preset experiment, fibrous root extract of C. chinensis (REC) was added into soil to study the effect of REC on microbes and enzyme activity in soil. The results showed that both bacteria and actinomycetes decreased by about 2 times in contrast to fungi, which increased by about 3 folds. Phosphorus bacteria, potassium bacteria, azotobacter, ammonia bacteria, and nitrifying bacteria were also reduced significantly by REC, suggesting the inhibition of nitrogen biofixation and supply, mobilization of phosphorus and potassium, ad plant growth promotion as REC added into soil. There were multiple influences of REC on soil enzyme activities. Invertase activity was stimulated, while urease was inhibited and dehydrogenase unchanged by REC, indicating the interference of biochemical reactions in soil. In addition, type and total content of phosphorus lipid fatty acids (PLFAs) , the signature of microbes, decreased while the ratio of bacterium to fungus PLFAs increased as REC increased in soil, which suggested that fungi increased relatively with bacteria decreased thereby leading to easy occurrence of crop fungus diseases following cultivation of C. chinensis. The decrease in diversity and evenness indexes of microbial community in soil by REC indicated soil ecosystem deterioration and reduction of microbial groups and densities in soil. Therefore, allelopathic chemicals released from the roots of C. chinensis could change microbial community structure and resulted in serious soil problems by continual cropping of this medicinal plant.

OBJECTIVE: To investigate the expression of hypoxia inducible factor 2α (HIF-2α) in every clinical stage and the pathological grade of epithelial ovarian cancer, and to discuss the role of HIF-2α in carcinogenesis, progression and outcomes of epithelial ovarian tumors. METHODS: Protein expression of HIF-2α in epithelial ovarian tissue from 77 randomly selected specimens was detected by SP immunohistochemistry staining. The relation between the expression of HIF-2α and prognosis of 40 patients with epithelial ovarian cancer was analyzed by Cox regression model. RESULTS: There was positive relation between the positivity rates of HIF-2α and malignant grade, FIGO stage, histological grade and invasive metastasis. The live time of the patients with HIF-2α positive expression was shorter than those with negative expression. CONCLUSION HIF-2α may play an important role in the genesis, development, invasion and metastasis of ovarian cancer and it may possess the vital clinical significance for prognosis evaluation.

Bone marrow mesenchymal stem cells (MSCs), multipotent stem cells, can replicate as undifferentiated cells and have the potential to differentiate into different lineages of mesenchymal tissues, including bone, cartilage,endothelial, neural, smooth muscle, skeletal myoblasts, and cardiac myocyte cells. The ischemia-induced death of cardiomyocytes results in scar formation and reduced contractility of the ventricle. Several preclinical and clinical studies have supported the notion that MSCs therapy may be used for cardiac regeneration.When transplanted into the infracted heart, MSCs prevent deleterious remodeling and improve recovery, but the mechanism is not clear. In this work,we review evidence and new prospects that support the use of MSCs in cardiomyoplasty.

Background and purpose: The aim of this study was to determine the necessity of central compartment neck dissection in laryngeal cancer.Study Design: Retrospective study at a tertiary referral medical center. Methods:Patients with laryngeal squamous cell cancer who underwent neck dissection were evaluated, and a retrospective analysis of clinicopathologic factors and follow-up data were performed. Results: One hundred and eighteen patients from 1999 to 2009 were enrolled. There were 11.9% central compartment lymph node metastasis in all patients, including the 10 patients with central compartment lymph node metastasis in 34 patients underwent compartment neck dissection and 4 patients do not underwent compartment neck dissection but had central neck recurrence in the follow up time. Subglottic or pyriform extension were risk factors in central compartment lymph node metastasis and central neck recurrence (P=0.002). Central compartment lymph node metastasis had closed relationship with levelⅣmetastasis (P<0.001), extracapsular extension (P=0.001), vascular extension (P=0.015) and poor local control rates (P=0.035) respectively. Patients who were positive for lateral neck lymph node metastasis had poor disease-free survival rate (P=0.014) and poor local control rates (P=0.025), and supraglottic cancer had a trend to metastases to levelⅡ(P=0.044). Conclusion:Central compartment neck dissection might be considered a potential therapeutic approach for patients with laryngeal cancer.
