Objective To assess the effect of inhalation of 20ppm nitric oxide(NO) on gas exchange and hemodynamics in acute lung injury induced by surfactant depletion in piglet.Methods Sixteen female piglets weighing 25-30 kg were induced with thiopental and pancuronium and maintained with continuous infusion of thiopental,fentanyl and pancuronium. The animals were tracheotomized and mechanically ventilated with oxygen(FiO 2=1.0). Femoral artery was cannulated for arterial blood sampling and blood gas analysis.Pulmonary catheter was inserted through the femoral vein for measurement of CVP, mean pulmonary artery pressure(MPAP), PCWP, cardiac output (CO) and sampling of mixed venous blood. Acute lung injury was induced by lung lavage after the method described by Lachmann until PaO 2 was lower than 100mm Hg(PaO 2/FiO 2

OBJECTIVE To explore the suitable hospital infection control measures in health centers of poverty-striken villages,in order to improve the management of hospital infection,decrease hospital infection rate and protect the health of medical staff and patients.METHODS The status quo of hospital infection in health centers of poverty-striken villages,was investigated in 20 small towns health centers with were randomly divided into two groups:test group(n=15)and control group(n=5).The suitable hospital infection control measures were explored from 5 points.The effect of infection control by before-after controlled study of experimental group and randomized controlled study of control group was anal yzed.RESULTS The rate of hospital infection in test group was decreased from 7.60% to 1.98% and at in control group didn't change,the difference was significant.CONCLUSIONS The managements of establishment of the suitable hospital infection control measures in health centers of poverty-striken villages have been put into practice and gained good result.

Results 216 aged patients with chest tumor were involved our study,Their clinical data were summarized and analized,All patients went smoothly through perioperative period,They recovered rapidly and discharged successfully from hospital,With no death occurred,postoperative complications occurred in a total of 36 cases(16.7%), But they were cured through meticulous management. Conclusions Aged patients with chest tumor could obstain good results by strict indications,fully risk evaluation and meticulous perioperative management.

Objective To study the expression and transcription of PKC? in renal tissue of streptozotocin-induced diabetic rats. Methods Hyperglycemia was induced with streptozotocin(55 mg/kg) in Sprague-Dawley rats. After 5 weeks, the expression of PKC? protein and mRNA was measured by immunohistochemistry, reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis. Results In diabetic animals, the expression of PKC? was greatly enhanced especially in the proximal tubules and the glomeruler mesangial areas with upregulating of the membrane-associated PKC?. RT-PCR analysis showed that mRNA level of PKC? increased by 1.67 folds in diabetic rats as compared with the normal ones. Conclusion The expression of PKC? protein and mRNA is upregulated in early diabetic nephropathy, which suggests an interaction between PKC? and the pathogenesis of diabetic nephropathy.

Objective To evaluate the expression and function of mammalian target of rapamycin (mTOR) and its substrate kinase P70S6K in mTOR/P70S6K signal pathway in cervical carcinogenesis. Methods The expression of mTOR and P70S6K in normal cervix uteri or cervical cancer was detected by the immunohistochemistry and RT-PCR methods. Results Compared to those in normal cervix uteri, both mRNA and protein of mTOR/P70S6K in cervical carcinomas were significantly increased (P<0.05). There was a positive correlation between mTOR gene and P70S6K gene expression in cervical cancer (r=0.746, P<0.001). Conclusion High expression of mTOR and P7OS6K may play an important role in the pathogenesis and development of cervical cancer.

We have studied the inhibitory effect of polysaccharides mixture on Ehrlich Ascites Carcinoma (EAC), Sarcoma 180 (S180), reticulocytic leukemia (L615) in mice. It is found that polysaccharides mixture could obviously prolong the survival duration of mice suffering from tumour and inhibit neoplastic proliferation. Thymus and adrenal glands atrophy in mice caused by vaccination of cancer cells was also remarkably resisted.The results of our experiments show that polysaccharides mixture is a safe,effective and promising pharmaceutic preparation of traditional Chinese medicine. It deserves to be further studied and developed.

Objective To improve X-ray and clinical knowledge of asphyxiating thoracic dysplasia(ATD).Methods X-ray film and CT findings of twin infants were studied meanwhile relative literature about ATD was reviewed.Results The main positive fingings of ATD were as follow:(1)The thoracic cages were both shorter than usual in the transverse and anterioposterior diameter;the anterior ends of the ribs are widened and cupped;(2)The pelvis also show abnormalities which include some flaring of the ilia,and early ossification of the centers for the capital femoral epiphyses;(3)Incureable respiratory infection was the prominent clinical manifestation.Conclusion ATD,a rarely seen disease,often occurs in those patients who suffer from pneumonia repeatedly;Because plain films can clearly show the relative characteristic deformity changes of thoracic cage and pelvis,X-ray examination can be regarded as the most important diagnostic method.

Purpose: To evaluate the efficacy, safety and survival of low molecular weight heparin ( LMWH) plus chemotherapy in patients with advanced non-small cell lung cancer. Methods: 46 patients with NSCLC were randomized into chemotherapy plus LMWH. (study group) and chemotherapy only( control group). Both groups received two cycles of MVP regimen (MMC 6 mg/m2, YDS 3 mg/m2 x 2, DDP 90 mg/m2). Patients in the study group were treated with LMWH 5000u twice daily from the third day before chemtherapy up to 7 days. Results: The response rate was 56. 5% (13/23) for the study group and 39. l%(9/23) for the control group. Median survival time( MST) and 1-year survival rate were 12, 1 months(95%CI:8.52~14.64) and 52.2% for the study group compare 8.4 months(95%CI:6.15 ~ 10. 85) and 34. 8% for the control group. There were significant differences for MST( 12. 1 vs 8. 4) and 1 year survival rate(52. 2% vs 34. 8%) in the study group as compared to the control group. No difference in response rate and toxicities were found between the two groups. Conclusions: Chemotherapy( MVP regimen) plus LMWH is effective and safe. Prolonged survival was observed in patients who received MVP regimen plus LMWH.

Objective To compare the safety of agomelatine and selective serotonin reuptake inhibitors (SSRIs) in the treatment of depression.Methods Retrieved literatures in the database at home and abroad from the built of the databases to March in 2016.The databases included Pubmed,Cochrance library,CNKI,Wanfang database and VIP database.Two researchers selected literatures,evaluated quality and extracted data independeatly.5.3.5 RevMan software was used to analyze.Result 87 literatures were retrieved,and nine English literatures and two Chinese literatures were included.Agomelatine had a lower risk than paroxetine in insomnia (RR:0.40,95％ CI:[0.17,0.92],P=0.03) and sexual dysfunction (RR:0.13,95％ CI:[0.04,0.39],P=0.0003),than fluoxetine(RR:0.68,95％ CI:[0.48,0.96],P=0.03) and paroxetine(RR:0.37,95％ CI:[0.25,0.55],P＜0.01) in nausea and vomiting,and than escitalopram in sweating(RR:0.34,95％ CI:[0.13,0.85],P=0.02) and headaches(RR:0.63,95％ CI:[0.43,0.91],P=0.01).The difference of them was statistically significant.Agomelatine had a higher risk than sertraline (RR:4.65,95％ CI:[1.02,21.16],P=0.05) in drowsiness,and than escitalopram in constipation (RR:3.46,95％ CI:[1.16,10.36],P=0.03),the difference was statistically significant too.Compared agomelatine and SSRIs,the occurrence risk of dry mouth and diarrhea were no significant difference.Conclusion Both agomelatine and selective serotonin reuptake inhibitors (SSRIs) had its pros and cons in terms of safety.Safety of agomelatine is better than paroxetine.Agomelatine and escitalopram had its own advantages and disadvantages respectively in safety.The evidence of the safety among agomelatine,fluoxetine and sertraline need further explore.
