MicroRNAs (miRNAs) are a class of small non-coding RNAs which involve in the regulation after gene transplantation.Researches show that miRNA is closely related to the development and progression of non-small-cell lung cancer (NSCLC).They caused a significantly change in NSCLC cells through downregulate tumor suppressor gene,or act as oncogene or work on some targets which is important in cell signal pathway,in the end it lead to oncogenesis,cell proliferation,cell apoptosis and resistance to chemotherapy or radiotherapy.Therefore,miRNA will be hopefully used in the diagnose and therapy of cancer.

Objective To investigate the effects of repeated high frequency transcranial magnetic stimulation (rTMS) on spatial learning and memory function,and on long-term potentiation (LTP) after global cerebral ischemia and reperfusion,and to explore the mechanisms involved.Methods Eighty-three male Wistar rats were studied.Five were tested to determine their average motor threshold (Tm).The others were divided into a normal control group,a cerebral ischemia and reperfusion model group and an rTMS group.Cerebral ischemia was induced with the four vessel occlusion method for 10 minutes.The rTMS treatment protocol (10 Hz stimulation for 5 s at the resting threshold,twice a day) was applied over a 2-week period from day 3 post-operation.The Morris water maze test was performed to observe spatial learning and memory at post-operation day 2 and day 4.The field excitatory postsynaptic potentials,population spike and the magnitude of long-term potentiation (LTP) induced by theta burst electric stimulation were recorded from the perforant path to the dentate gyrus (PP-DG).Results At post-operation day 3,rats in the untreated cerebral ischemia and reperfusion model group exhibited a significant decrease in the magnitude of the PP-DG LTP as compared to the normal group.No significant difference in LTP was found between the model group and the rTMS group.After the 2 weeks of treatment the LTP levels in the rTMS treated group were significantly higher than in the two untreated groups.In the Morris water maze testing,the average escape latency in the rTMS group was significantly shorter than that of the cerebral ischemia and reperfusion model group (which was not treated).In the probe trials,the time in the original quadrant of the platform and the time of crossing the platform were both significantly less for the rTMS-treated rats than for those not treated.Conclusions High frequency rTMS can improve spatial learning and memory after global cerebral ischemia and reperfusion by enhancing the LTP induced in the hippocampus.High frequency rTMS might exert this beneficial effect by modulating the function of intermediate neurons in the hippocampal neuronal network and by promoting neurotransmitter release.

Objective To investigate the hemodynamic effects and mechanisms of aerosolized iloprost in children with pulmonary hypertension(PAH)after congenital heart surgery,in the setting of early ventilation and continuous nitric oxide(NO)inhalation were administered.To observe the outcomes of the patients after iloprnst therapy.Methods From April 2008 to April 2009,all postoperative children with PAH in ICU,Fuwai hospital had regularly been given ventilation and NO inhalation at a dose of 10 ppm for 2 hours since they were leaving the operation room,and then ultrasonic cardiography was used to evaluate the systolic pulmonary arterial pressure(sPAP=4×TIVmax+RAP).Thirty children were diagnosed as having postoperative PAH for sPAP/sBP≥0.5.They were divided into two groups(group T and group C)randomly,with ventilation and NO inhalation administered continuously,and were given inhaled iloprost at a dose of 100 ng·kg-1·min-1*10 min and inhaled 0.9% NaCl 4ml respectively,once every 4 hours for 48 hours.We used the 24-hour cardiac monitors and ultrasonic cardiography for hemodynamic monitoring in the patients of two groups at the six time points:baseline(t1),20 min later after the first inhalation(t2),120 min later after the first inhalation(t3),24 hours later after the treatment(t4),48 hours later after the treatment(t5) and 24 hours after ceasing the last inhalation(t6).We examine the blood cAMP and cGMP by ELISA assay before and after the first inhalation.We observed the blood coagulation,the liver and kidney function of these patients.The outcomes of these patients were also investigated.Results At t1,the sPAP and sPAP/sBP had no differences between the two groups.At t2,the sPAP(43.23±11.72)mmHg and sPAP/sBP(0.48±0.13)in group T were both lower than the sPAP(53.13±13.60)mmHg and sPAP/sBP(0.60±O.15)in group C(P<0.05).At t3,the sPAP/sBP of group T was also lower than that of group C(0.48±0.09 vs 0.59±0.14,P<0.05).At t4 and t5,the sPAP in group T were (39.84±12.87)and(34.99±12.98)mm Hg,with sPAP/sBP(0.42±0.15)and(0.36±0.14),were much lower than those in group C(P<0.01).From t1 to t2,the cAMP level increased sharply from(406.64±179.18)to(578.68±193.05)pg/dl in group T(P<0.01),and was also obviously higher than that in group C at t2(392.26±94.46)pg/dl(P<0.01).HR,BP and RAP showed no notable difference between two groups at every time point.So did the PIP.There were no differences in coagulation,liver and kidney function at t6.2 patients died from pulmonary hypertension crisis(PAH)in group C and no one in group T.One patient showed flush during the treatment in group T and recovered spontaneously after the inhalation.Nevertheless,none in group C.Conclusiou Inhaled iloprost significantly improved pulmonary hemodynamics in children with PAH after congenital heart operation even thongh they were ventilated and inhaling NO.Increased blood cAMP level was considered to be a contributing factor.Howeve,systemic BP remain unaffected after iloprost inhalation.Aerosolized iloprost may be associated with improvement in the survival and deczeased PHC.

AIM: To analyze and summarize the effect of glaucoma trabeculectomy in the department of ophthalmology in basic hospital.
METHODS: Postoperative intraocular pressure ( IOP ) , filtering bleb and complications of 316 cases (405 eyes) of patients with glaucoma after trabeculectomy were analyzed.
RESULTS: After follow- up 12mo, 76. 5% IOP was controlled in normal level. 42. 5% was filtration bleb typeⅠ, 33. 1% typeII, 14. 6% in typeⅢand 9. 9% in typeⅣ. Intraoperative complication rate was 2. 5%, that was 31.4% at postoperative early stage ( before discharge ) , and 6. 7% at postoperative long - term ( 6mo after discharge) .
CONCLUSION:Trabeculectomy for glaucoma can better solve the problem of high IOP. It is more mature in primary hospitals, but there are still a variety of intraoperative and postoperative complications.

Objective To study the therapeutic effects of inhaled iloprost on pediatric pulmonary hypertension after congenital heart disease operation and to investigate the mechanisms of iloprost.Methods Thirteen 10 min every time,every 4 hours for 48 h after the surgery.We used the 24 h cardiac monitoring and ultrasonic cardiography for hemodynamical monitoring.We examined the blood cAMP and cGMP by ELISA assay.Results The patients were(17.88±12.56) months old with average weight of(9.29±3.59) kg.The right atrial pressure,systolic pulmonary arterial pressure,systolic pulmonary arterial pressure/systolic blood pressure were(11.5±1.41)mm Hg,(61.64±13.6) mm Hg and 0.66±0.16 before the treatment and they were(9.88±1.88) mm Hg,(47.67±12.18) mm Hg and 0.52±0.15 at the time point of 20 min after the treatment.For all the three parameters,there were significant differences before and after treatment.The effect of iloprost continues to 120 min later.The cAMP level was(335.75±127.31) μg/L before iloprost inhalation and increased to(519.68±148.54)μg/L at the time point of 20 min after inhaling iloprost,showing a significant difference(P＜0.01).Blood pressure,cGMP level and ventilator parameters showed no notable difference before and after the treatment.Conclusion Inhaled iloprost significantly improves pulmonary hemodynamics in children with pulmonary hypertension after congenital heart disease operation,which might be achieved by increasing the blood cAMP.However,systemic blood pressure and respiratory function keep unaffected after iloprost inhalation.
