1.Surgical treatment of unilateral destroyed lung
International Journal of Surgery 2009;36(8):562-565
Destroyed lung has resulted in the pathological changes of irreversible lung damage. The variety of reasons cause lobes of lung or the side of the whole lung loss of function and volume decrease. To the side of lung damage for patients.,it is necessary to take the whole side of surgical resection of lung disease at the right time Not only it can quickly alleviate the respiratory symptoms, but also can significantly improve the patients quality of life. Even some benign disease can be cured to achieve the purpose. Because of the extensive fibrosis of lung tissue loss of the affected lung function. Patients have varying degrees of shortness of breath and recurrent cough, cough purulent sputum, hemoptysis. Because of the thickened parietal pleura,those result in the effect of bad medical treatment. Most need surgical treatment, but the surgery cause perioperative patient physiological condition of interference, Major trauma surgical procedures, much more bleeding, and many and serious postoperative complications, those require a higher surgical technique. The article summed up the whole lung damage lung surgical methods and progress were reviewed.

Objective To determine the changes in event-related potentials (ERPs) and examine the relationship between memory, consciousness and ERPs during propofol sedation and anesthesia. Methods Ten young healthy volunteers were enrolled in this study. Baseline values of ERPs, noninvasive BP (NBP), ECG and SpO2 were recorded before induction of sedation and anesthesia. The level of sedation was assessed using OAA/S scale. Sedation and anesthesia were induced and maintained with target-controlled infusion (TCI) of propofol. The amplitude, peak value and latency of the potential N1 and P3, NBP ECG and SpO2 were recorded at each level of sedation and anesthesia. A list of words was played via headphone at OAA/S score of 3 or 2. Memory test was performed 4hr after the recovery from anesthesia. Target and distractor hits in inclusion and exclusion test were obtained and explicit and implicit memory scores were calculated. Results (1) At OAA/S score of 3 the amplitude of N1 was attenuated and that of P3 suppressed ( P

Objective:To investigate the effect of microRNA-146a (miR-146a) on apoptosis of human retinal microvascular endothelial cells (HRMECs) induced by high glucose and its possible molecular mechanism.Methods:HRMECs were cultured in vitro with 5.5 mmol/L D-glucose in the normal control group and 25 mmol/L D-glucose in the high glucose group for 48 hours, respectively.Normally cultured HRMECs were transfected by miR-146a mimics in the high glucose+ miR-146a mimics group or corresponding mimics control in the high glucose+ mimics control group by lipofection and cultured with 25 mmol/L D-glucose for 48 hours, respectively.Real-time fluorescent quantitative polymerase chain reaction (PCR) was performed to detect the expression level of miR-146a.MTT assay and flow cytometry were used to detect the activity and apoptosis of HRMECs, and Western blot was employed to detect the expression levels of apoptosis-associated protein B-cell lymphoma factor-2 (Bcl-2), Bcl-2 related X protein (Bax) and nuclear factor-κB (NF-κB) signaling-related proteins NF-κB p65 and p-NF-κB p65. Results:The relative expression levels of miR-146a were 1.00±0.10, 0.22±0.02, 0.21±0.02 and 0.88±0.09, and the cell viability was (100.00±10.06)%, (68.41±6.67)%, (67.91±6.74)% and (90.46±8.97)%, and the apoptosis rates were (3.11±1.02)%, (27.28±3.56)%, (27.44±4.03)% and (7.29±2.11)% in the normal control group, high glucose group, high glucose+ mimics control group and high glucose+ miR-146a mimics group, respectively.The relative expression levels of miR-146a and the cell viability were significantly lower, and the cell apoptosis rate was significantly higher in the high glucose group than those in the normal control group, with statistical significant differences (all at P<0.05). The relative expression levels of miR-146a and the cell viability were significantly higher, and the cell apoptosis rate was significantly lower in the high glucose+ miR-146a mimics group than those in the high glucose group and the high glucose+ mimics control group, and the differences were statistically significant (all at P<0.05). The relative expression levels of Bax and p-NF-κB p65 protein were significantly higher, the relative expression level of Bcl-2 protein was significantly lower in the high glucose group than those in the normal control group, showing statistically significant differences (all at P<0.05). The relative expression levels of Bax and p-NF-κB p65 protein were significantly lower, and the relative expression level of Bcl-2 protein was significantly higher in the high glucose+ miR-146a mimics group than those in the high glucose group and the high glucose+ mimics control group, and the differences were statistically significant (all at P>0.05). There was no significant difference in the relative expression of NF-κB p65 protein among the groups ( F=0.106, P=0.955). Conclusions:Overexpression of miR-146a may inhibit the apoptosis of HRMECs induced by high glucose, and its mechanism may be related to the inhibition of NF-κB signaling pathway activation.

Objective To assess the value of tomographic ultrasound imaging (TUI) for prenatal analysis of the relative orientation of fetal heart and great arteries. Methods Volume datasets acquired from 12 patients of transposition of the great arteries (TGA) and 13 normal fetal heart were evaluated offline with TUI. The aortic valves (AV) and pulmonary valves (PV) were respectively showed on the two parallel slices. According to the pivot point in the middle of the PV in one slice, the relative orientation of the AV on another slices were analyzed. Results In the 12 patients of TGA confirmed postnatally, 7 were concomitant with single ventricle anomaly, AV was on the anterior-right orientation of the PV in 5, and was relatively on the anterior and anterior-left orientation in other 2 of them.In the remained 5 with seeming normal 4 chamber view, AV was found on the anterior-right of the PV in 3, and was relatively on the anterior and upright orientation.in other 2 patients. In 13 normal fetuses, TUI showed that all AV located on the posterior-right orientation to the PV. Conclusion TUI can provide detailed spatial information of the great arteries both in normal and abnormal fetal heart. It may be a convenient and veracious tool for prenatal exploring the morphology of the great arteries.

Objective To observe the vasodilation effect of extract of Jasminum samba (EJs), a kind of traditional Chinese medicine, on ex vivo rat thoracic aortic rings, and to investigate its mechanism. Methods On ex vivo aortic ring perfusion device, influence of EJs on contraction of the aorta induced by phenylephrine (PE) or potassium chloride (KCl) was observed. Influence of N-nitro-L-arginine-methylester ( L-NAME ), barium chloride ( BaCl2 ), glibenclamide ( Gli ) on vasodilating effect of EJs (0. 5, 1, 2, 4, 8 g·L-1 ) was detected. Effect of EJs on the contraction of calcium chloride (CaCl2 ) and PE in Ca2+-free medium was detected. [ Ca2+ ] i in vascular smooth muscle cells was determined by using laser scanning confocal microscope (LSCM). Results In blood vessels with intact endothelium, EJs concentration-dependently decreased PE- or KCl-induced vasoconstriction, the maximum dilating effect being (105. 0±3. 2)% and (78. 0±6. 5)% , respectively; L-NAME affected the vasodilatory effect of EJs on thoracic aorta rings ( P<0. 01), the maximum dilatory effect being (58. 0 ± 6. 9)% . BaCl2 and Gli had significant influence on vasodilation of EJs, and the contraction was obviously attenuated (P<0. 01), the maximum dilatory effect being (37. 0±5. 2)% and (78. 0±10. 0)% , respectively. EJs significantly inhibited contracting effect of PE on thoracic aorta rings in Ca2+-free medium (P<0. 01). The maximum contraction effect was (70. 0±6. 3)% . EJs inhibited CaCl2-induced vasoconstriction (0. 5-8 mmol·L-1 ), and vasoconstriction was decreased by (65. 0±3. 2)% . LSCM recorded that Fmax / F0 of 4 and 8 g·L-1 EJs was (2. 0±0. 2) and (1. 5±0. 2), respectively. Conclusion EJs exerted a dose-dependent vasodilating effect on rat isolated aorta rings. The mechanism might be related to promoting NO release, activating K+channels and decreasing the concentration of cytoplasmic Ca2+.
