AIM: To study the effect of herbal compound poria prescription (CPP) on proliferation and differentiation in primary rat preadipocytes, and to explore the mechanism of this process. METHODS: Primary cultured rat preadipocyte proliferation was determined by cell counting and MTT spectrophotometry. Cell differentiation was determined by Oil Red O staining, and the expression of PPAR? mRNA was determined by RT-PCR. RESULTS: CPP inhibited the proliferation and differentiation of primary rat preadipocytes in a dose-dependent manner, and it also inhibited the expression of PPAR? mRNA. CONCLUSION: CPP inhibits the proliferation of primary rat preadipocytes and inhibits the preadipocyte differentiation by suppressing the expression of PPAR? mRNA.

AIM: To investigate the effect of compoun d poria prescription (CPP), a Chinese medicine, on weight, blood glucose, blood fa t and microcirculation in nutrition obesity rats and attempt to look for a new a pproach for obesity prevention and cure. METHODS: 30 Wistar rats were divided into normal food raised gro up (group A), high energy food raised group (group B), and high energy food comb ined with CPP raised group (group C). The changes of weight, blood glucose, bloo d lipid and microcirculation were detected, respectively. RESULTS: After CPP treatment in experimental obesity rats, the a v erage weight reduced from (313.00?17.29) g to (217.50?17.50) g (P

AIM AND METHODS: Using Ca 2+ -sensitive fluorescent probe Fura-2,we measured the changes of _i in cultured rat pulmonary artery endothelial cells (PAEC) and porcine pulmonary artery smooth muscle cells (PASMC) from normoxic (NC group) or chronic hypoxic group (CH group) when they were exposed to acute hypoxia. RESULTS: The increase in _i in 6th passage of PASMC caused by acute hypoxia in CH group was significantly lower than that in the same passage of NC group (P

Objective To investigate the relationship between protein phosphatase inhibition, tau hyperphosphorylation and neuronal death seen in Alzheimer disease (AD). Methods Co culture of protein phosphatase inhibitor okadaic acid (OA) and neuroblastoma cells (SH SY5Y), by agarose gel electrophoresis to detect DNA fragmentation, and in situ hybridization by TdT mediated biotin labeled dNTP nick end labeling (TUNEL) to further detect the cell apoptosis. Results Incubation of SY5Y cells with 10 nmol/L OA for 24 or 48 hours led to the appearance of DNA fragmentation and a remarkable increase of positive cells from 2 16%?0 94% to 18 05%?3 57% ( P

Transient receptor potential ankyrin 1 (TRPA1) is a family member of the transient receptor potential (TRPs). It is primarily localized to a subpopulation of primary sensory neurons, such as trigeminus, vagus and dorsal root ganglia. Neuropathic pain is often caused by peripheral nerve injury, diabetes and chemotherapeutics. A large of oxidative/nitrative stress products are produced during neuropathic pain, which cause acute nociception, allodynia, and hyperalgesia. TRPA1 antagonists may be beneficial in the treatment of neuropathic pain. Here, the role of TRPA1 in neuropathic pain is summarized.

Objective To explore the related risk factors and control measures for senium patients with type 2 diabetes and to provide basis for making control and prevention measures.Methods A retrospective case-control study was conducted.548 cases of type 2 diabetes patients in our hospital were selected as case group and other 640 cases of normal people who accepted physical examination in our hospital were selected as control group.Results Exposure rates of smoking,drinking,obesity,hypertension,hypedipidemia and family history in case group were obviously higher than those of control group(P ＜0.05).Conclusion Smoking,drinking,obesity,hypertension,hyperlipidemia and family history were risk factors of type 2 diabetes.Comprehensive intervention measures related to the risk factors,such as maintaining a good way life,were importantto prevent and control type 2 diabetes.

Roles of sympathicus, sensory neuropeptides (SNP), metabolites of cyclooxygenase, metabolites of lipoxygenase, endothelium derived relaxing factor (EDRF), reactive oxygen (ROS) and potassium channels (PC) in the hypoxic pulmonary vasoconstriction (HPV) and hypoxic cerebral vasodilation (HCVD) were studied in intact rats, rabbits and dogs. Results were as follows: during hypoxia, the excitation of sympathicus results in a constriction of both pulmonary and cerebral vessels; SNP, EDRF and the opening of 4-AP sensitive PC caused the dilation of both of them; metabolites of lipoxygenase mediated HPV and HCVD, whereas metabolites of cyclooxygenase were their modulators; hypoxia induced blockade of the ATP sensitive PC mediated HPV, but had no effect on HCVD; reduction of O_2~+ in the lung might potentiate HPV, but had no effect on HCVD. It is suggested that the alteration of lipoxygenase metabolites, ROS and ATP sensitive PC are factors accounting for the difference in response of pulmonary and cerebral vassels to hypoxia.

Objective To explore the clinical value of cranial CT for the patients in neurological ICU by analyzing the application of mobile CT scanner CereTom in some hospital.Methods Retrospective analysis was carried out for the patients being hospitalized and undergoing cranial CT examination in some hospital from March 2012 to August 2014.Results Totally 261 patients and 325 times of examination were involved in, and two ones failed in the examination, with the success rate of 99.23%. There were 218 patients (83.52%) had the examination completed in one time and 43 ones (16.48%) in several times. It's proved that bedside CT could be applied clinically with high successful rate. The mean time of bedside CT examination was (18.3±3.8)min, significantly less that then of common examination.Conclusion Mobile CT may decrease moving-related risk of the patient and the time, manpower consumed for examination, and thus is worth popularizing clinically.

AIM: To explore the effects of 5-HT and electrolytes on the airway remodeling in guinea pigs with bronchial asthma.METHODS: 70 guinea pigs were divided into 7 groups: control group,model group,continued model group,5-HT group,anti-5-HT group,high Mg~(2+) group,low Mg~(2+) group.Remodeling model was established with ovalbumin.RESULTS: ① In model group,5-HT of serum and thickness of airway walls were significantly increased compared with control group(P

AIM:To investigate the role of potassium channel expression alteration in chronic cigarette smoking-induced increase in pulmonary vascular responsiveness,the effect of chronic cigarette smoking on large-conductance calcium-activated potassium channel(BKCa) and voltage-dependent delayed rectifier potassium channel(Kv1.5) expression in rat pulmonary smooth muscle cells were investigated in vivo.METHODS: HE staining,immuno-histochemistry and in situ hybridization techniques were used.RESULTS:(1) Chronic cigarette smoking downregulates the protein and mRNA expression of BKCa in pulmonary arterial smooth muscles.(2) Chronic cigarette smoking downregulated the protein and mRNA expression of Kv1.5 in pulmonary arterial smooth muscles.(3) In big artery,BKCa decreased more makedly than Kv1.5,but in small artery,both of them decreased equally.CONCLUSION: Chronic cigarette smoking downregulates the levels of BKCa and Kv1.5 in rat pulmonary arterial smooth muscle cells in vivo,which maybe contribute to the mechanism of cigarette smoking-induced increase in pulmonary vascular responsiveness.
