Objective To improve the knowledge for flow direction of renal spleen circulation in Budd Chiari syndrome and effects in treatment. Methods Two Budd Chiari syndrome patients with reno splenic venous shunt were treated by PTA, and the circulation directions were investigated. Results One case with hepatic vein occlusion showed the circulation from left renal spleen vein to IVC; another case with IVC stenosis proximal to heart showed the flow direction from spleen left renal vein to varices and finally to SVC. The circulation disappeared after treatment with PTA.Conclusions The direction of circulation in different types of Budd Chiari with portal hypertension may be different and should be identified clearly for a suitable management.

Objective:To observe the clinical efficacy and adverse reactions of paroxetine combined with olanzapine in the treat-ment of depression complicated with sleep disorders. Methods: Totally 150 cases of sleep disorder patients were selected, and then randomly divided into the control group and the observation group with 75 ones in each. The control group was given paroxetine treat-ment, the observation group was given paroxetine combined with olanzapine treatment, and the treatment course was four weeks. The sleep latency, total sleep time, wake-up time and the number of awakening in the two groups were recorded, and the HAMD scale score and treatment efficacy were compared. Results:Compared with those in the control group, the sleep latency, total sleep time, wake-up time and the number of awakening in the observation group were obviously improved (P<0. 05). The clinical cure rate, the HAMD scale score and the incidence of adverse reactions between the two groups all had significant differences (P<0. 05). Conclu-sion:Paroxetine combined with olanzapine in the treatment of depression with sleep disorders shows fast efficacy, which can improve the sleep disorder symptoms and reduce the incidence of adverse reactions significantly.

Objective To investigate the effects of miR-335-5p on the proliferation and apoptosis of osteoblasts which were exposed to high glucose condition, and explore its possible molecular mechanisms. Methods MC3T3-E1 osteoblasts were divided into four groups:control group(5. 5 mmol/L glucose), high glucose group(HG group, 22. 0 mmol/L glucose), agomir-335-5p group(transfected with agomir-335-5p and exposed to 22. 0 mmol/L glucose) , and agomir negative control group( agomir NC group, transfected with agomir negative control and exposed to 22. 0 mmol/L glucose), cultured for 7 days. Cell proliferaton, cell apoptosis, expressions of miR-335-5p and dickkopfhomolog1(DKK1)mRNA,proteinlevelsofDKK1andcysteinylaspartate-specificproteinase-3(caspase-3) were detected using MTT, flow cytometry, quantitative realtime PCR and western blot, respectively. Results Compared with control group, the expression of miR-335-5p mRNA and cell proliferation in HG group were significantly decreased(P<0. 05), while cell apoptosis and the protein levels of DKK1 and caspase-3 were increased significantly(P<0. 05), the expression of DKK1 mRNA did not change (P>0. 05). The miR-335-5p mRNA expression and cell proliferation in agomir-335-5p group were higher than those in HG group and agomir NC group(P<0. 05). However, Cell apoptosis and the protein levels of DKK1 and caspase-3 in agomir-335-5p group were lower than those in HG group(P<0. 05). Conclusion High glucose inhibits the proliferation and induce the apoptosis of MC3T3-E1 osteoblast through decreasing the expression of miR-335-5p and subsequently increasing the DKK1 expression.

Objective To investigate the changes of bone mineral density (BMD) and its causing factors in menopausal female patients with type Ⅱ diabetes mellitus (DM2). Methods Dual energy X ray absorptimetry was used to measure the BMD of lumbar spines (L 2-4 ) and proximal femur in 82 female patients with type Ⅱ diabetes and 46 normal controls. According to BMD, DM2 patients were divided into two groups (DM A and DM B). Fasting plasma glucose (FPG), fasting plasma insulin (FINS), fasting plasma C peptide (FCP), glycated hemoglobin (HbAc1), urine albumin excretion rate (UAER), and urine ? 2 microglobin (? 2 MG) were measured and compared between the two groups. Results BMD of lumbar spines (L 2-4 ), femoral neck and Ward's triangle in diabetic patients were significantly lower than that of the controls ( P

Objective To intelligently adjust the driving force of a remote-controlled drug delivery capsule based on the postural information in intestines,so as to achieve the control of speed and dosage of drug delivery and reduce the energy consuming.Methods A six-axis sensor MPU6050 was used,and its Z axis was coincident with the central axis of the drug delivery capsule so as to made the medicine discharge port pointing to the Z direction.The angular velocities and accelerations of X,Y,Z axes were monitored,transformed to quaternion with built-in digital motion processor,and then converted to Euler angle form.The intelligence adjustment of driving force could be achieved by accessing the real-time attitude angle of the capsule.Results The results of experiments showed that the error between the actual and the attitude angle measured by the sensor was less 1°.Conclusions The intelligent adjustment scheme of driving force of a gastrointestinal remote-controlled drug delivery capsule was designed.The real-time attitude angles of the capsule could be obtained with high spped and precision.This study can provide the theoretical and experimental basis for the intelligent adjustment of the driving force.

BACKGROUND:Valvular interstitial cel s are the main components of the heart valves. Myofibroblasts, as a kind of valvular interstitial cel s, can express alpha-smooth muscle actin and type I col agen fiber, and hold differentiation potential. These cel s cannot only play a support role in the valve structure, but also play a regulatory role in the process of the valve normal physiological and pathological responses.
OBJECTIVE:To obtain a reliable method of separation, primary culture and identification of myofibroblasts laying a foundation for further study on the cardiac valvular calcification.
METHODS:Aortic valve myofibroblas extracted from porcine hearts were primary cultured by trypsin and col agenase combined digestive method, common enzyme-digestion method and tissue-culture method, respectively. The myofibroblast activity and morphology were observed using microscope, and myofibroblasts were identified using light microscope and immunocytochemistrial method.
RESULTS AND CONCLUSION:Myofibroblasts had a higher activity and purity cultured by trypsin combined with col agenase II digestion method. Aortic valve myofibroblasts were positive for alpha-smooth muscle actin and negative for von Wil ebrand factor under fluorescence microscope, suggesting that myofibroblasts were successful y obtained.
