Objective To observe the effects of microRNA-21 (miR-21) inhibitor on apoptosis of type Ⅱalveolar epithelial cells (AEC Ⅱ) in rats with hyperoxia-induced acute lung injury (HALI).Methods Eighty Sprague-Dawley (SD) rats were divided into air-control group,hyperoxia injury group,empty-virus control group (200 μL solution with lentivirus was dropped into the nasal) and miR-21 inhibitor pretreatment group (200 μL solution with lentivirus contained miR-21 inhibitor was dropped through the nasal) by random number table.After treatment,the rats in all groups were fed in the hyperoxia incubator with oxygen concentration exceeding 90％ for production of HALI model,and the rats in air-control group were fed normally without any treatment.Ten rats were selected at 0,24,48 and 72 hours after exposure in hyperoxia environment respectively,and the general changes of lung tissues were observed in light microscope.The right lung tissues were harvested to observe the pathological changes under light microscopy.The left lung tissues of other 10 rats in each group were harvested at 48 hours after execution,the miR-21 expression was determined by real-time fluorescence quantitative reverse transcription-polymerase chain reaction (RT-qPCR),the protein expression of cysteinyl aspartate-specific proteinase-3 (caspase-3) was determined by Western Bolt,and apoptosis of AEC Ⅱ was detected by TdT-mediated dUTP nick end labeling (TUNEL).Results ① No abnormal appearance in lung tissues was observed at all time points in the air-control group.In hyperoxia injury group,the lung injury would be more severe if the exposure time was longer,and lung tissues turned dark red after exposure for 72 hours,with patchy hemorrhage in several places;the structure of lung tissues was disordered,the alveolar wall was broken,the alveolar septum was significantly edematous and broadened,and there was plenty of inflammatory cell infiltration and edema fluid appeared inside the alveolar space.In miR-21 inhibitor pretreatment group,the degree of lung tissue injury was more severe than that of the hyperoxia injury group,and there was no significant change in empty-virus control group.(②) Compared with air-control group,miR-21 expression of the hyperoxia injury group was significantly decreased (2-△△Ct:0.021 ± 0.005 vs.0.037 ± 0.006),and the protein expression of caspase-3 was significantly increased (A value:0.423±0.081 vs.0.123±0.023,both P ＜ 0.05).After pretreatment with miR-21 inhibitor,the expression of miR-21 was further decreased (2-△△Ct:0.014±0.003 vs.0.021 ±0.005),while the protein expression of caspase-3was further increased (A value:0.691 ±0.085 vs.0.423 ±0.081,both P ＜ 0.05).There were no statistically significant differences in the expression of miR-21 (2-△ △ct:0.025 ± 0.007 vs.0.021 ± 0.005) and caspase-3 (A value:0.475 ± 0.062vs.0.423 ±0.081) between empty-virus control group and hyperoxia injury group (both P ＞ 0.05).(③) Compared with air-control group,the apoptosis cells in hyperoxia injury group were increased,which was further increased after pretreatment of miR-21 inhibitor,but no changes were found in empty-virus control group.Conclusion Inhibition of miR-21 expression in vivo could aggravate the injury of lung tissue in HALI rats,and increase the apoptosis of AEC Ⅱ.

AIM: To investigate the inhibition of the recombinant human endostatin adenavirus (Ad-Es) on the experimental choroidal neovascularization(CNV) models by intravitreous injection.METHODS: Experimental CNV models were induced by semiconductor laser in 30 male Brown Norway(BN) rats and randomly divided into 3 groups with 10 rats in each group.At 21d after photocoagulation, the single administration group were given intravitreous injection with Ad-Es 0.01mL;the repeated administration group were given intravitreous injection with Ad-Es 0.01mL and a repeated injection 7d later;the saline control group were given intravitreous injection with saline 0.01mL.At 7d after final administration, the leakage of fundus fluorescein angiography (FFA) was observed.Various CNV areas were measured by using laser confocal microscopy of choroidal flatmount method.Pathology and ultrastructure were observed with light microscopy, the expressions of CD105 were measured by immunohistochemistry.RESULTS: The leakage of CNV of the administration group abviously decreased as compared with those in the saline group, the leakage of repeated administration group decreased compared with that of single administration group (P<0.05).Laser confocal microscope quantitative CNV analysis showed that CNV area of the administration group was significantly smaller than that of control group, the area of repeated administration group was smaller than that of single administration group (P<0.05).Under the light microscope, the vascular endothelial cell number and quantity of the administration group were significantly lower than that of the control group, the cell number of repeated administration group was lower than that of single administration group.CD105 expression of the administration group was significantly weaker than that in the saline group;the expression of repeated administration group was weaker than that of single administration group.CONCLUSION: Ad-Es can effectively inhibit semiconductor laser induced CNV in BN rats, and the inhibition effect of repeated administration group is better than that of single administration group.It may be a useful new method in the treatment of CNV.

ObjectiveTo investigate the dosage of protamine to counteract heparin in patients with different pH values of after - surgery plasma of congenital heart defect.MethodsThe clinical data of 108 patients during March 2011 to April 2011 with congenital heart diseases who underwent cardiopulmonary bypass(CPB) surgery were reviewed.The volumes of chest tube drainage were analyzed to investigate the dosage of protamine in patients with different pH values in plasma.ResultsThe dosages of protamine and the volumes of chest tube drainage[ ( 136.8 ± 22.8 ) ml] in patients with an acidic environmental plasma were higher than the patients in another group [ ( 112.6 ± 22.7 ) ml ] ( P＜ 0.01 ).In patients with non-acidic environments,the mean ratio of dosage of protamine to heparin was 1.23:1 ; meanwhile in patients with pH＜7.30 or base excess (BE) ＜ -6,the mean ratio was 1.86:1.It suggested the dosage of protamine increased significantly in patients with an acidic environmental plasma.ConclusionsDifferent plasma pH values could change the dosage of protamine after cardiopulmonary bypass,and the acidic environment would increase the dosage of protamine and increase the volume of chest tube drainage after surgery.When pH ＜ 7.30 or BE ＜ - 6 at the end of CPB,to correct acid-base balance first and then calculate the dose of protamine was recommended.

Objective To evaluate the clinical value of prone flexed posture lumber CT/MRI examination for lumber disc herniation. Methods Supine posture CT/MRI (SPCT/MRI) and prone flexed posture CT/MRI (PFPCT/MRI) examinations were performed on 1200 patients with lumber disc herniation.The imaging findings on SPCT/MRI and PFPCT/MRI of each case were compared. According to the CT/MRI diagnostic criteria for encapsulated lumber disc herniation ( HLDH ), adhered lumber disc herniation (ALDH) and ruptured lumber disc herniation ( RLDH), the 1200 cases were divided into three groups. On the basis of PFPCT/MRI findings, 868 cases were selected for percutaneous lumbar diskectomy (PLD) with half to twelve years follow up. Treatment effects of PLD on HLDH, ALDH and RLDH were analyzed with x2test. Results Among 249 ALDH cases diagnosed by SPCT/MRI 35 were identified as HLDH by PFPCT/MRI. Among 163 RLDH cases diagnosed by SPCT/MRI, 9 HLDH and 17 ALDH were identified by PFPCT/MRI. In 868 cases treated with PLD, the effective rate of HLDH ( n = 832), ALDH ( n = 25 ), RLDH ( n =11 ) were 825/832 (99. 2% ), 13/25, and 1/11 respectively. The effective rate of HLDH is significantly different from that of ALDH and RLDH ( x2 = 369. 69, P ＜ 0. 01 ). Conclusion PFPCT/MRI may change the grouping result of lumber disc herniation made by SPCT/MRI and can be used to objectively select patients for PLD.

Objective:To explore whether microRNA-21-5p (miR-21-5p) has the effect of anti-apoptosis of human alveolar typeⅡ epithelial cells (ATⅡ).Methods:ATⅡ cells derived from the human were cultured in vitro and used for experiments when the cells were grown until the presence of lamellar bodies and microvilli were observed by light microscope. The cells were divided into blank control group (direct culture), hydrogen peroxide (H 2O 2) injury group (cultured with 0.5 mmol/L H 2O 2), and miR-21-5p overexpression group (using miR-21-5p with a multiplicity of infection (MOI) of 100 lentiviral overexpression vector with 0.5 mmol/L H 2O 2) and miR-21-5p empty virus control group (miR-21-5p lentiviral blank vector was co-cultured with 0.5 mmol/L H 2O 2). In each group, cell proliferation was detected by cell counting kit-8 (CCK-8) at 0, 12, 24, 36, and 48 hours of cell culture; cell apoptosis was detected by flow cytometry at 24 hours of culture. Results:① Cell proliferation activity test results: with the extension of cell culture time, the cell proliferation activity of the blank control group gradually increased, while the cell proliferation activity gradually decreased after the addition of 0.5 mmol/L H 2O 2. However, the cells proliferation activity in the miR-21-5p overexpression group decreased more slowly than that in the H 2O 2 injury group and the miR-21-5p empty virus control group, and the cell proliferation activity at 48 hours was significantly higher than the H 2O 2 injury group and the miR-21-5pempty virus control group ( A value: 0.295±0.005 vs. 0.184±0.005, 0.169±0.002, both P < 0.05). It showed that both H 2O 2 and lentivirus accelerated cell damage, while miR-21-5p could reduce cell apoptosis. ② Apoptosis rate test results: compared with the blank control group, the apoptosis rate increased significantly after adding 0.5 mmol/L H 2O 2; while the apoptosis rate of the miR-21-5p overexpression group was lower than that of the H 2O 2 injury group and miR-21-5p empty virus control group [early apoptosis rate: (14.31±0.12)% vs. (24.50±0.12)%, (23.41±0.13)%; late apoptosis rate: (8.12±0.13)% vs. (9.71±0.11)%, (10.41±0.15)%; overall apoptosis rate: (22.33±0.12)% vs. (34.21±0.10)%, (33.82±0.14)%; all P < 0.05], which further proved that miR-21-5p had anti-apoptotic effects. Conclusion:miR-21-5p has an anti-apoptotic effect on human ATⅡ.

Objective To explore the advantages of the technique of bile duct mini-incision (BDM) for stone removal in choledocholithiasis,and to further clarify the indications for T tube insertion during surgery.Methods 85 BDM operations were performed.The use of MRCP (Magnetic resonance cholangiopancreatography),Advantage Workstation AW4.2 0.7sdc software,choledochoscopic imaging system and illustrations were used to study the applicability of the BDM technique in stone removal.Results The width of common bile duct (CBD) was usually over 8 mm in the patients with choledocholithiasis,and the width was related to the number and size of the stones.In the patients who had a CBD width of over 11mm (n 16),the MRCP stone imaging area (MRCP-SIA) was significantly larger when compared with that [(148±67)mm2 vs.(47±31)mm2,P＜0.05] in the patients (n=14) with CBD width of less than 11 mm.T tube insertion for secondary choledochoscopic examination should be performed when the stones were non drifting,multiple,and closely related to the lower part of CBD indicating difficulty in complete stone removal.Conclusions Unnecessary T tube insertion could be avoided by the BDM technique for stone removal which was especially suitable for patients with early diagnosis of choledocholithiasis.T tube insertion should only be performed in patients with difficulty in complete stone removal and in other complicated situations.

Objective: To investigate the impact for family history of hypertension on masked hypertension (MH) morbidity with relevant cardiac damage. Methods: Our research included in 3 groups: MH group, n=250 consecutive patients treated in our hospital from 2010-01 to 2015-04, Hypertension group, n=250 and Control group, n=250 subjects with normal blood pressure. The family history of hypertension, general clinical information, routine biochemical indexes and the findings of echocardiography were studied and compared among different groups. Results: ① There were 70 (28%) patients with family history of hypertension in MH group, 87 (34.8%) in Hypertension group and 26 (10.4%) in Control group. The ratio of family history of hypertension in MH group was higher than Control group, P<0.001, while it was similar between MH group and Hypertension group, P>0.05. Logistic regression analysis presented that family history of hypertension and body mass index were positively related to the morbidities of MH (r=1.468, r=0.173) and hypertension (r=1.195, r=0.086). ② Compared with Control group, MH group had increased left ventricular mass index (85.64 ± 17.7) g/m2 vs (80.50 ± 15.53) g/m2 and the maximum blood flow velocity of aortic valve (115.74 ± 16.54) cm/s vs (112.40±14.21) cm/s, all P<0.05. In MH group, compared with those without family history of hypertension, the patients with family history had the higher left ventricular mass index (89.22 ± 19.08) g/m2 vs (84.25 ± 16.99) g/m2 and the maximum blood flow velocity of aortic valve (119.19 ± 14.97) g/m2 vs (114.39 ± 16.96) g/m2, all P<0.05. Conclusion: The subjects with family history of hypertension had the higher risk of MH morbidity with more severe cardiac damage.
