OBJECTIVE: To observe the effects of Huanglian Jiedu Decoction (HLJDD), a traditional Chinese compound herbal medicine, on p85 mRNA and protein expressions of phosphatidylinositol-3-kinase (PI-3K) in target tissues (skeletal muscular and adipose tissues) in rats with type 2 diabetes mellitus (T2DM) and to investigate the molecular mechanism of HLJDD in treating T2DM. METHODS: The male Wistar rats were injected with streptozotocin (STZ) 30 mg/kg through tail vein, and fed with high-fat and high-caloric diets to induce T2DM. Then the rats were randomly divided into untreated group, aspirin-treated group and HLJDD group, and treated correspondingly. Meanwhile, a group of normal animals without any treatment was set up for normal control group. Ten weeks later, serum fasting blood glucose (FBG), serum fasting insulin (FINS) and oral glucose tolerance test (OGTT) were routinely determined. The expressions of PI-3K p85 mRNA and protein in skeletal muscle and adipose tissue were determined with RT-PCR and Western blotting before and after insulin treatment. RESULTS: Compared with the untreated group, the FBG and OGTT levels in T2DM rats treated with HLJDD decreased significantly (P<0.05). The FINS in HLJDD group was lower than that in the normal control group (P<0.05), but was not significantly different from that in the untreated group. The PI-3K p85 mRNA and protein expressions in HLJDD group obviously increased, as compared with those in the untreated group. CONCLUSION: The effect of HLJDD in treating T2DM was probably associated with its improvement of PI-3K p85 mRNA and protein expressions in skeletal muscle and adipose tissue of the T2DM rats.

Ultrasonic microbubbles were used to open blood-brain barriers (BBB) with a reversed and limited behavior feature in the study, which could improve the brain-targeted delivery of anti-tumor drugs. The glioma rat model was prepared. Low-frequency ultrasound was combined with microbubbles to affect the permeability of BBB compared with the permeability of independently administered Evans blue (EB) crossing BBB. Time point and length of ultrasound were investigated whether they affect the permeability of BBB and the damage of brain tissue. The effect of the growth time of glioma on BBB permeability was explored. Only glioma had a very little impact on BBB permeability. However, ultrasonic microbubbles opened the BBB with the features of temporary, limited and reversed behavior and improved EB and magnetic resonance imaging contrast agent penetrating BBB. A length of 30 s ultrasound is appropriate for opening BBB and no damage of brain tissue. Drugs should be injected before ultrasound so that they enter into brain as BBB opening. Ultrasonic microbubbles can open BBB effectively and safely, which improve drugs penetrating BBB under proper time point and length.

Objective To assess the diagnostic predictive value of Wells score and modified Geneva score for acute pulmonary embolism by prospective case series and to explore a more suitable scoring system for Chinese population.Methods All the patients suspected of pulmonary embolism (PE) and received CT pulmonary angiography (CTPA) were enrolled consecutively in Fuxing Hospital,Capital Medical University,China,from June 2009 to August 2011.Before CTPA test or on condition that test results were unknown,clinical scoring was assessed prospectively by the Wells score and the modified Geneva score.The probability of PE in each patient was assessed and the patients were divided into low,moderate and high probability groups according to the clinical scores.The result of CTPA was used as the diagnostic gold standard for PE.Diagnostic accuracy in each group was analyzed.The predictive accuracy of both scores was compared by AUCROC curve.Results A total of 139 patients met our enrollment criteria and 117 eligible patients entered our study at last.PE was diagnosed in 47 patients by CTPA with an overall prevalence of 40.2％.Prevalence of PE in the low,moderate and high pretest probability groups assessed by the Wells score and by the simplified modified Geneva score were 7.1％ (3/42),42.9％ (21/49),88.5％ (23/26)and 10.0％ (3/30),48.1％ (37/77),7/10,respectively.AUCROC curves for the Wells score and the simplified modified Geneva score were 0.872 ( 95％ CI 0.810-0.933 ) and 0.734 ( 95％ CI 0.643-0.825 )respectively,with a significant difference ( P =0.005 ).Conclusion The Wells score is more accurate for clinical predicting acute PE than the modified Geneva score.

A patient with severe hypoglycemia due to insulin-like growth factor ( IGF)-IIsecreted by a giant solitary fibrous tumor of the pleura ( SFTP) was investigated through comprehensively reviewing his medical history and clinical records. The patient had severe hypoglycemia accompanied with significantly decreased serum insulin level. A solitary fibrous tumor of the pleura was found, and right pneumonectomy removed this giant tumor. Two years after the operation, the patient was fit and well with no further hypoglycemia episodes. Non-islet-cell tumor hypoglycemia should be considered in patients who have hypoglycemia episodes accompanied with significantly decreased serum insulin level.

The effects of ultrafine grinding on the dissolution rates of the effective components in Sanjie Zhentong capsule (SZC) were studied in this experiment. Fine and ultrafine powder of SZC intermediates were made by ordinary grinding and ultrafine grinding technology, and then granulated by wet granulation. SZC were prepared by fine powder, ultrafine powder and ultrafine granules, respectively. With resveratrol and loureirin B as investigated indexes, dissolution rates of the four intermediates in SZC were determined by cup method and HPLC. The dissolution rates of resveratrol in SZC prepared by fine powder, ultrafine powder and ultrafine granules were 26.11%, 63.27%, 67.49%, respectively; and the dissolution rates of loureirin B were 7.160%, 20.29%, 23.05%, respectively. The dissolution rate of resveratrol and loureirin B in SZC prepared by ultrafine granules was the best. D90 size of ultrafine grinding was 13.221 μm and could improve the dissolution rates of resveratrol and loureirin B in SZC.
