4.Group Lasso Penalized Classifier for Diagnosis of Diseases with Categorical Data.
Journal of Biomedical Engineering 2015;32(5):965-969
Six kinds of erythemato-squamous diseases have been common skin diseases, but the diagnosis of them has always been a problem. The quantitative data processing method is not suitable for erythemato-squamous data because they are categorical qualitative data. This paper proposed a new method based on group lasso penalized classification for the feature selection and classification for erythemato-squamous data with categorical qualitative data. The first categorical data of 33 dimensions were changed by the virtual code, and then 34th dimension age data were discretized and changed by the virtual code. Then the encoded data were grouped according to class group and variable group. Lastly Group Lasso penalized classification was executed. The classified accuracy of 10-fold cross validation was 98.88% ± 0.002 3%. Compared with those of other method in the literature, this new method is simpler, and better for effect and efficiency, and has stronger interpretability and stronger stability.

8.Effects of mechanical ventilation with different tidal volumes on coagulation/fibrinolysis in rabbits with acute respiratory distress syndrome
Chinese Critical Care Medicine 2015;(7):585-590
ObjectiveTo observe the effects of mechanical ventilation with different tidal volumes (VT) on coagulability and fibrinolytic characteristics in rabbits with acute respiratory distress syndrome (ARDS) induced by two-hits with oleic acid (OA) and lipopolysaccharide (LPS).Methods Forty healthy adult male rabbits were randomly divided into five groups (8 rabbits in each group): sham operation group, model group, low VT group (6 mL/kg), rontine VT group (10 mL/kg), high VT group (15 mL/kg). ARDS model was reproduced by sequential injection of 0.1 mL/kg OA and 500μg/kg LPS via auricular vein, and the rabbits in sham operation group received normal saline in same volume. Mechanical ventilation was performed in different VT groups after model reproduction, and the end of the experiment was determined as 6 hours after LPS injection. Blood was collected from the carotid artery at 30 minutes and 360 minutes after LPS injection, with which arterial partial pressure of oxygen (PaO2) was determined, and oxygenation index was calculated. Internal jugular vein blood was collected at 5, 120, 240, and 360 minutes after LPS injection, and activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (Fib) and antithrombinⅢ(AT-Ⅲ) were determined. The blood was collected at the end of the experiment, and then the rabbits were sacrificed, and serum levels of procollagen typeⅢ (PⅢP), plasminogen activator inhibitor-1 (PAI-1) as well as PⅢP level in lung tissue were determined. The wet/dry weight ratio (W/D) of lung tissues was calculated.Results Compared with sham operation group, oxygenation index at both 30 minutes and 360 minutes were significantly decreased in model group, while W/D ratio was significantly increased. PT and APTT at 5 minutes were significantly shortened followed by a gradual increase. Fib and AT-Ⅲ showed no change at 5 minutes followed by a gradual decrease, while serum PAI-1 and PⅢP as well as PⅢP in lung tissue were significantly increased. There was no significant difference in oxygenation index between all VT groups and model group, with a tendency to increase in low VT group. W/D ratio in low VT group was the lowest (5.09±0.19), and it was significantly lower than that of the model group (6.02±0.27, P< 0.01), while it was the highest in high VT group (6.27±0.32). PT and APTT in all VT groups were gradually prolonged, and Fib and AT-Ⅲ were gradually decreased. PT and APTT in low VT group were significantly shorter than those in model group from 120 minutes on [PT (s): 120 minutes: 8.90±0.28 vs. 11.43±0.28, 240 minutes: 9.18±0.21 vs. 11.99±0.50, 360 minutes: 9.25±0.15 vs. 12.49±0.29; APTT (s): 120 minutes: 69.09±3.91 vs. 76.08±4.21, 240 minutes: 67.53±2.14 vs. 79.71±2.25, 360 minutes: 66.95±1.13 vs. 83.21±4.01, allP< 0.05], Fib (g/L) was significantly elevated (120 minutes: 3.80±0.09 vs. 3.38±0.15, 240 minutes: 3.91±0.05 vs. 2.47±0.16, 360 minutes:4.06±0.13 vs. 2.39±0.16, allP< 0.05), and no significant difference was found in AT-Ⅲ. Serum contents of PAI-1 and PⅢP as well as PⅢP in lung tissue were significantly lowered [serum PAI-1 (ng/L): 1.14±0.26 vs. 1.63±0.91, serum PⅢP (ng/L): 1.62±0.52 vs. 2.91±0.64, lung PⅢP (ng/L): 4.40±0.58 vs. 5.75±0.47, allP< 0.01]. The change tendency of all parameters in routine VT group was lower than that in low VT group, PT at 120 minutes and 360 minutes, APTT at 240 minutes and 360 minutes was significantly shorter than that in model group, and Fib at 120 minutes and 240 minutes were significantly higher than those in model group (allP< 0.05). No significant difference was found in AT-Ⅲ, serum PAI-1 and PⅢP as well as lung PⅢP as compared with model group. PT and APTT at 360 minutes in high VT group were significantly longer than those in model group, Fib at 360 minutes was significantly lower than that in model group, and lung PⅢP was significantly higher than that in model group. Conclusions There are some important changes in coagulability which changes from a hyper state into a hypo coagulate state, while fibrinolysis is inhibited during the pathological process of ARDS produced by two-hit of OA and LPS. Mechanical ventilation with low VT can obviously improve coagulability and fibrinolytic status, while ventilation with routine VT has little effect on coagulability and fibrinolytic status. Mechanical ventilation with high VT, however, will greatly deteriorate the coagulability and fibrinolytic function in ARDS.

10.Relationship among different types and subunits of calcium channels and antihypertensive drugs
Chinese Pharmacological Bulletin 1986;0(05):-
This paper elucidates the relationship among different types and subunits of voltage-gated calcium channels and antihypertensive drugs.①L-type calcium channels lack of functional expression in renal efferent arterioles,but it has been found recently that T-type calcium channels have had roles in the regulation of renal efferent arteriolar tone.Third generation dihydropyridine,L-type calcium channel antagonists including manidipine,nilvadipine,benzindamine and efonidipine,can dilate both afferent and efferent renal arterioles,then improve glomerular hypertension and provide renoprotection,because the inhibition of both L and T type calcium channels.② In hypertensive rats,an increased expression of L-type calcium channel ?1c subunits has been shown.and this increased expression of calcium channel ?1c subunit associated with the increase of Ca2+ influx and elevated arterial tone can be observed.These findings provide a rational basis for designing antihypertension therapy by normalizing Ca2+ channel ?1c subunit expression.
