ObjectiveTo determine whether the inhibition of caveolin-1 tyrosine residues 14 (Cav-1-Y14) phosphorylation with protein tyrosine kinase inhibitors (PP2) will upregulate heme oxygenase-1 (HO-1) activity to protect against ventilation induced lung injury in vivo of an animal model.Methods Fifty-four male Sprague-Dawley (SD) rats were randomly divided into nine groups (eachn = 6). Group A served as normal control group, in which rats did not receive ventilation but tracheotomy. Groups B1 and B2 received lung protective ventilation respectively for 1 hour or 2 hours. Groups C1 and C2 received high tidal volume (40 mL/kg) ventilation for 1 hour or 2 hours, respectively. The group D1 or D2 also received high tidal volume ventilation for 1 hour or 2 hour respectively, but they were given PP2 1 hour before high tidal volume ventilation. The groups E1 and E2 also received high tidal volume ventilation respectively for 1 hour or 2 hours, but tyrosine kinase inhibitor PP2 and HO-1 inhibitor zinc protoporphyrinⅨ(ZnPPⅨ) were given to animals 18 hours before high tidal volume ventilation. All the animals were sacrificed after ventilation, and the specimens of lung tissues and bronchoalveolar lavage fluid (BALF) were harvested. Then the changes in pathology of lung tissue was observed, and diffuse alveolar damage scores (DAD) were calculated, myeloperoxidase (MPO) activity was measured by colorimetric analysis, lung wet/dry ratio (W/D) was estimated. The expressions of phosphorylated caveolin-1 (P-Cav-1-Y14), caveolin-1 (Cav-1) and HO-1 were determined by Western Blot. The expressions of high mobility group B1 (HMGB1) and advanced glycation end product receptor (RAGE) in lung tissues were assayed with immunohistochemistry staining. The levels of tumor necrosis factor-α(TNF-α) in BALF were measured by enzyme linked immunosorbent assay (ELISA).Results There was no significant difference in all the parameters between group A and groups B. Compared with group B1, DAD score, W/D ratio, the activity of MPO and the concentration of TNF-α in BALF in group C1 were significantly increased [DAD score:7.97±0.59 vs. 0.55±0.13, W/D ratio: 5.70±1.61 vs. 5.04±0.63, MPO (U/g): 1.82±0.14 vs. 0.77±0.26, TNF-α(ng/L): 370.10±29.61 vs. 54.38±8.18, allP< 0.05], and the injury in ventilation 2 hours group was more serious than that in ventilation 1 hour group. Compared with groups C, all the parameters in groups D were significantly decreased. The parameters in groups E were significantly higher than those in groups A, B, and D, but no significant difference was found as compared with groups C. Compared with groups B, the protein expressions of Cav-1 and P-Cav-1-Y14 (gray value) in groups C were significantly increased (1 hour: 1.49±0.02 vs. 1.26±0.13, 1.34±0.02 vs. 0.87±0.04;2 hours: 1.58±0.02 vs. 1.27±0.27, 1.31±0.01 vs. 0.95±0.02, allP< 0.05), and the expression of HO-1 protein (gray value) was significantly decreased (1 hour: 0.59±0.02 vs. 1.10±0.01, 2 hours: 0.49±0.01 vs. 1.20±0.02, both P< 0.05). No significant difference in Cav-1 protein expression between groups D as well as groups E and groups C. The protein expression of P-Cav-1-Y14 in groups D and E was significantly lower than that in groups C. The protein expression of HO-1 in groups D was significantly higher than that in groups C, but the phenomenon was not found in groups E as compared with groups C. Compared with group A, the positive expression of HMGB1 and RAGE in lung tissue in groups C and E was significantly increased, but no significant difference was found between groups B as well as groups D and group A.Conclusion Cav-1-Y14 phosphorylation is the key factor for ventilator induced lung injury, which can not only lead to a decrease in vascular barrier function, but also inhibit the activity of HO-1 enzyme, thus further aggravates inflammatory injury of the lung as induced by mechanical ventilation.

OBJECTIVE:To observe the efficacy and safety of eprosartan in the treatment of hypertensive patients with coro-nary heart disease. METHODS:160 hypertensive patients with coronary heart disease randomly divided into observation group and control group. All patients were given aspirin,nitroglycerin,low molecular weight heparin,statins and other conventional treat-ment;control group was additioanlly given 50 mg Losartan potassium tablet,orally,once a day. Observation group was additional-ly given 600 mg Eprosartan tablet,orally,once a day. The treatment course for both groups was 6 months. Clinical efficacy,sit-ting systolic blood pressure and diastolic blood pressure,alanine aminotransferase(ALT),aspartate aminotransferase(AST),urea (UREA),creatinine(Cr),uric acid(UA),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol (LDL-C),the Mini-Mental status (MMSE) scale and activities of daily living (ADL) scale scores before and after treatment and incidence of adverse reactions in 2 groups were observed. RESULTS:There was no signifi-cant difference in the total effective rate between 2 groups(P>0.05). After treatment,the sitting systolic blood pressure and diastol-ic blood pressure,MMSE and ADL scale scores in 2 groups were significantly lower than before,and sitting systolic blood pres-sure in observation group was lower than control group,the differences were statistically significant(P<0.05),and there were no significant differences in sitting diastolic blood pressure,MMSE and ADL scale scores between 2 groups(P>0.05),and no signifi-cant differences in ALT,AST,UREA,Cr,UA,TC,TG,HDL-C and LDL-C between 2 groups before and after treatment(P>0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Eprosartan can effectively reduce sitting systol-ic blood pressure in hypertensive patients with coronary heart disease,and improve cognitive function,with good safety.

OBJECTIVE:To study the effects and mechanism of propranolol on the myocardial abnormal electrophysiology sta-tion in diabetic model rats. METHODS:SD rats were randomly divided into normal control(normal saline)group,diabetic(nor-mal saline)group,PD98059(ERK inhibitor,10 mg/kg)group and propranolol low-dose,medium-dose and high-dose(1,20,50 mg/kg)groups,with 8 rats in each group. Except for normal control group,rats were given alloxan(20 mg/kg)intravenously via tail vein to induce diabetic model. They were given relevant medicine intragastrically,once a day,for consecutive 42 days. The car-diac index,electrocardiogram and action potential durations (APD) of rats were analyzed;the expression of TNF-α,IL-2,IL-6 and IL-10 protein in serum were detected,and the expression of Ras,Raf,ERK kinase(MEK)and ERK1/2 in myocardial tissue were detected. RESULTS:Compared with normal control group,cardiac index increased in diabetes group;heart rate decreased;QT interval and APD were prolonged;the relative expression of TNF-α,IL-2,IL-6,IL-10,Ras,Raf,MEK and ERK1/2 protein increased (P<0.01). Compared with diabetes group,cardiac index decreased in propranolol medium-dose and high-dose groups and PD98059 group,heart rate increased,QT interval and APD were shortened;the relative expression of TNF-α,IL-2,IL-6, IL-10,Ras,Raf,MEK and ERK1/2 protein decreased(P<0.05 or P<0.01). CONCLUSIONS:Propranolol can improve myocar-dial abnormal electrophysiology station of diabetic model rats by down-regulating inflammatory reactions in serum and inhibiting the activation of MEK/ERK signaling pathway.

Objective To investigate whether the inhibition of caveolin-1 (Cav-1) phosphorylation will regulate effectively nuclear factor-erythroid 2-related factor (Nrf2) signal pathway and downstream effector molecules and protest against ventilation induced lung injury (VILI) in an animal model in vivo. Methods Ninety male Sprague-Dawley (SD) rats were randomly divided into nine groups (each n = 10): sham group in which rats did not receive ventilation but received tracheotomy; lung protective ventilation (PV) for 1 hour or 2 hours group; mechanical ventilation (MV) at high volume tidal (VT, 40 mL/kg) for 1 hour or 2 hours group; protein tyrosine kinase inhibitor PP2 or rosiglitazone (Rsg) pretreatment + high VT ventilation for 1 hour or 2 hours groups. The two pretreatment groups were given intraperitoneal injection PP2 15 mg/kg or intragastric administration of Rsg 5 mg/kg 1 hour before ventilation respectively. The rats were sacrificed after model reproduction, and bronchoalveolar lavage fluid (BALF) was collected. Pulmonary vascular permeability was measured by Evans blue (EB). The levels of tumor necrosis factor-α (TNF-α), activator protein-1 (AP-1), nuclear factor-κB (NF-κB), and interleukin-8 (IL-8) in BALF were determined by enzyme linked immunosorbent assay (ELISA). Then the lung tissues were collected, the lung wet/dry ratio (W/D) was calculated, the changes in pathology was observed with light microscope, and myeloperoxidase (MPO) activity was determined by colorimetric analysis. Nrf2 mRNA was determined by reverse transcription-polymerase chain reaction (RT-PCR). The expressions of Cav-1 tyrosine residues 14 phosphorylation (pCav-1-Y14), Cav-1, peroxisome proliferators-activated receptor γ (PPARγ) and claudin-5 as well as Nrf2 in cytoplasm and nucleus were determined by Western Blot. The positive expressions of PPARγ and claudin-5 in lung tissues were assayed with immunohistochemistry staining. Results There were no obvious pathological changes in the lung tissue in sham group and PV groups, and there were no significant differences in all the parameters between the two groups either. However, the injury in lung tissue was severe in the high VT groups in which W/D ratio, EB contents, MPO activity, and TNF-α, AP-1, IL-8, NF-κB levels in BALF as well as the protein expressions of Cav-1 and pCav-1-Y14 were significantly higher than those of sham group and PV groups, and the protein expressions of PPARγ and claudin-5 were significant lower than those of sham group and PV groups with a dose-dependent manner; but Nrf2 expressions in cytoplasm and nucleus did not show a statistical increase. After pretreatment of PP2 or Rsg, W/D ratio, MPO activity, EB contents, TNF-α, AP-1, IL-8, and NF-κB in BALF were significantly decreased as compared with those of high VT group, and RT-PCR showed significant up-regulation of Nrf2 mRNA in lung tissues too. Moreover, there was a statistically significant increase in expressed Nrf2 proteins in nucleus in PP2 or Rsg groups as compared with those of high VT groups [Nrf2 in nucleus (gray value): 0.61±0.06, 0.56±0.06 vs. 0.31±0.02 at 1 hour, 0.38±0.06, 0.43±0.07 vs. 0.22±0.03 at 2 hours; all P < 0.05], but no significant difference was found in the expression of Nrf2 protein in the cytoplasm among all groups. The protein expressions of pCav-1-Y14 in PP2 pretreatment groups were significantly lower than those of high VT groups (gray value: 0.89±0.04 vs. 1.48±0.02 at 1 hour, 0.86±0.02 vs. 1.31±0.01 at 2 hours; both P < 0.05); but expressed PPARγ proteins and expressed claudin-5 proteins in PP2 or Rsg pretreatment groups were significantly higher than those of high VT groups [PPARγ (gray value): 0.34±0.07, 0.42±0.13 vs. 0.17±0.07 at 1 hour, 0.38±0.09, 0.33±0.07 vs. 0.16±0.03 at 2 hours; claudin-5 (gray value): 0.33±0.05, 0.38±0.07 vs. 0.14±0.03 at 1 hour; 0.30±0.06, 0.31±0.04 vs. 0.17±0.04 at 2 hours; all P < 0.05]. Conclusions The inhibition of Cav-1-Y14 phosphorylation can increase the expression of Nrf2 in the nucleus, then result in an increase in the protein expressions of PPARγ and claudin-5 of its effector molecules. This effect can reduce the inflammation and capillary permeability of lung tissue in the model of VILI.

ObjectiveTo observe effect of OT training on patients wearing the upper limd prosthesis. MethodsThe effect of OT to 30 patients with upper arm prosthesis was analyzed using FIM score before and after training.

ObjectiveTo investigate the rule of changes of the soleus mass and expression of myosin heavy chain (MHC) isoforms mRNA.Methods40 female Wistar rats were divided randomly into the control group and three spinal cord transection (ST) groups, ST7, ST15, and ST30 with 10 animals in each group. Rats in ST groups were subjected to a complete ST between T8 and T10 levels. The right soleus was dissected and weighed at 7, 15, 30 days after ST, and the expression of MHC mRNA isoforms was measured by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR).ResultsThe Absolute and relative soleus masses in three ST groups were lower significantly than those of control group (P<0.05). The soleus mass in ST15 and ST30 groups were lower than that of ST7 group (P<0.05). The soleus of control group predominantly expressed MHC-I and some MHC-IIa, whereas the soleus began to express MHC-IIx and MHC-IIb after ST, except for MHC-I and MHC-IIa. ST induced consistently down-regulation of MHC-I mRNA and up-regulation of MHC-IIx and MHC-IIa at three time points after ST. The level of MHC-IIb mRNA expression was very low at three time points after ST.ConclusionST can influence the soleus mass at early stage after ST. ST induces a shift toward a faster muscle phenotype from slow to fast MHC isoform. MHC demonstrates plasticity in response to decrease neuromuscular activation.
