Journal of International Oncology 2017;44(5):351-355
Objective To investigate the expressions and relationships of human epididymal secretory protein 4 (HE4),osteopontin (OPN) and urokinase-type plasminogen activator (uPA) in endometrial carcinoma (EC) and analyze their clinical significance of detection and diagnosis in EC patients.Methods The expressions of HE4,OPN and uPA proteins in 30 cases of normal endometrium,50 cases of precancerous lesion endometrium and 171 cases of EC were detected by immunohistochemistry SP method.The relationships between HE4,OPN,uPA and clinicopathological features of EC,and the correlation of them were analyzed.Results The positive expression rates of HE4,OPN and uPA in the normal endometrium group,precancerous lesion endometrium group and EC group were 13.3%,32.0%,70.8%;10.0%,24.0%,63.7%;6.7%,22.0%,51.5%.The differences were statistically significant (x2 =46.36,P < 0.05;x2 =44.14,P < 0.05;x2 =28.10,P < 0.05).The expressions of HE4,OPN and uPA were correlated withpathological stage (x2 =4.644,P =0.031;x2 =5.780,P =0.016;x2 =28.920,P =0.000),histological grade (x2 =4.888,P =0.027;x2 =7.885,P =0.005;x2 =4.564,P =0.033),myometrial invasion depth (x2 =5.099,P =0.024;x2=5.139 P=0.023;=12.297,P=0.000) and lymph node metastasis (x2 =5.421,P=0.020;x24.093,P =0.043;x2 =5.362,P =0.021).In addition,the expression of HE4 was correlated with the histological type (x2 =4.437,P =0.035).HE4 expression was positively correlated with uPA expression (r =0.341,P =0.007).OPN expression was positively correlated with uPA expression (r =0.360,P =0.002).HE4 was positively correlated with OPN expression (r =0.454,P =0.000).Conclusion The expression rates of HE4,OPN and uPA in the EC group were higher than that in normal endometrium and precancerous lesions.They have obvious positive synergistic effect in the occurrence and development of EC.HE4,OPN and uPA are the effective indicators for clinical diagnosis of EC.
2.Postoperative tear dysfunction of LASIK and SMILE
Chinese Journal of Experimental Ophthalmology 2016;34(9):847-850
Tear dysfunction was considered as abnormalities of tear film composition that include the presence of pro-inflammatory cytokines.Recent studies indicated that altered tear composition caused dysfunction,accelerated death and detachment of the superficial epithelium,leading to an irregular corneal surface,an unstable tear layer and hyperesthesia of the corneal nerve endings.Symptoms of tear dysfunction after laser in situ keratomileusis (LASIK) and small incision lenticule extraction (SMILE) present in many patients.This review summarized the clinical characteristics of tear dysfunction in post-LASIK and post-SMILE patients,analyzed the potential mechanism of tear dysfunction and reasonable management.
3.The research progress on nutritional risk and nutritional support in children with sepsis
Chinese Pediatric Emergency Medicine 2016;23(2):107-112
Sepsis is a major problem in the pediatric critical care medicine.The related research indi-cates that the nutrition risk may be one of the risk factors that affect the incidence and mortality of sepsis. Through nutritional risk screening and assessment,it can be used to provide reference for assessing the nutri-tional risk,the nutritional support and the effect of nutritional support on prognosis of children with sepsis.At present,there are few studies on the nutritional risk and nutritional support in children with sepsis.In this arti-cle,we reviewed the research progress on nutritional risk and nutritional support in children with sepsis.
4.Neuroprotective effect of inhibition of soluble epoxide hydrolase on focal cerebral ischemia/reperfusion in Rats
International Journal of Cerebrovascular Diseases 2013;(2):108-113
Objective To investigate the neuroprotective effect of soluble epoxide hydrolase (sEH) inhibitor 12-(3-adamantan-l-yl-ureido) dodecanoic acid (AUDA) on focal cerebral ischemia/reperfusion in rats and its mechanisms.Methods Sixty male Sprague-Dawley rats were randomly divided into sham operation and saline control groups,as well as low-dose (0.157 ml/kg),medium-dose (0.235 ml/kg) and high-dose (0.314 ml/kg) AUDA groups (n =12 in each group).Four rats in each group were selected for infarct volume,cell apoptosis and p-Akt immunohistochemistry detection.A model of middle cerebral artery ischemia/ reperfusion was induced by the suture method.The corresponding dose AUDA or equal volume of saline was injected intraperitoneally before reperfusion in each AUDA group and the saline control group.Neurological deficit scores were performed at 24 h of reperfusion.2,3,5 triphenyltetrazolium chloride (TTC) staining was used to detect infarct volume.TdT-mediated dUTP nick end labeling (TUNEL) was used to detect apoptotic cells of brain tissue in the periinfarction area.Immunohistochemical method was used to detect p-Akt expression of brain tissue in the peri-infarction area.Results TTC staining showed no infarction was observed in the sham operation group.The infarction volumes in the saline control group as well as the low-dose,medlum-dose and high-dose AUDA groups were 254.146 ± 25.481,212.679 ± 7.514,150.188 ± 33.997,and 99.563 ± 3.415 mm3,respectively.There were significant differences (F =39.637,P =0.000).The each dose AUDA group was significant less than the control group (all P=0.000).The medium-dose AUDA group was significantly less than the low-dose AUDA group (P=0.002),and the high-dose AUDA group was also significantly less than the low-dose AUDA group (P =0.000) and medium-dose AUDA group (P =0.006).TUNEL staining showed that a small number of apoptotic cells (6.400 ± 1.477/high-power field) were observed in the sham operation group.The numbers of apoptotic cells in the saline control group as well as in the low-dose,medium-dose and high-dose AUDA groups were 57.550 ± 13.067,47.030 ± 8.423,34.530 ± 4.393 and 26.400 ± 2.683/high power field,respectively.Each dose AUDA group was significantly less than the saline control group (all P <0.01).The medium-dose and high-dose AUDA groups were significantly less than the low-dose AUDA group (P < 0.01),and the high-dose AUDA group was also significantly less than the medium-dose AUDA group (P <0.01).Immunohistochemistry showed that only a few p-Akt-positive cells (3.325 ± 1.438/high power field) were observed in the sham operation group.The numbers of p-Akt-positive cells in the saline control group as well as the low-dose,medium-dose and high-dose AUDA groups were 9.450 ±2.531,16.400 ± 3.865,22.875 ± 7.974,and 29.300 ± 3.203/high-power field,respectively.Each dose AUDA group was significantly more than the saline control group (all P <0.01).The medium-dose and high-dose AUDA groups were significantly more than the low-dose AUDA group (all P <0.01).The high-dose AUDA group was also significantly more than the medium-dose AUDA group (P < 0.01).Conclusions The inhibition of sEH may decrease neuronal apoptosis and reduce infarct volume in the peri-infarction area by upregulating the PI3K/Akt pathway.It has a neuroprotective effect for focal cerebral ischemia/reperfusion in rats.

7.Interpretation of the third universal definition of myocardial infarction
Chinese Journal of Laboratory Medicine 2013;(6):485-488
Myocardial infarction (MI) is a major cause of death and disability worldwide.The definition of myocardial infarction has been updated.Released in 2012,Third Universal Definition of Myocardial Infarction of ESC/ACCF/AHA/WHF Expert Consensus,made the clinical application value of troponin clear and suggested to monitor the dynamic changes of cTn in patients with suspected,emphasized the importance of clinical differential diagnosis.In consensus,it also noted that the application of high sensitive troponin can lead to false positives results,and pointeds out that in the assessment of cardiac injury associated with percutaneous or surgical coronary procedures,the rational cut-off value of cTn remains controversival.In addition to acute coronary syndrome,cTn elevations are common in many disease states,and with the improvement of detection sensitivity,low level increase of cTn,will be more.In acute and chronic heart failure,the cTn is elevated,and ACS may be the cause of worsening heart failure,So we should identify whether the cTn elevation is pure from the myocardial injury of heart failure or myocardial necrosis caused by ACS.Nowadays,the increased incidence of myocardial infarction has much to do with the wide application of cTn.Clinical applications of cardiac biomarkers and imaging techniques are flexible as the differences in the diagnostic techniques of myocardial infarction among countries and regions result.

12 gestational-week uterus) were treated in our hospital by LAVH. The operation time,intraoperative blood loss,and postoperative recovery of the patients were compared to another 110 cases that underwent TAH. Results The operation time in the TAH group was significantly shorter than that in the LAVH group [(109?27) min vs (130?22) min,t=-6.441,P=0.000]. During the operation,the LAVH group had a mean of (121?70) ml blood loss,which was significantly lower than that in the TAH group [(141?73) ml,t=-0.903,P=0.368]. After the operation,the patients in the TAH group had longer recovery time for gastrointestinal function and longer hospital stay than those in the LAVH group [(45?13) h vs (24?6) h,t=15.778,P=0.000;and (7?2) d vs (5?2) d,t=7.530,P=0.000]. Conclusions Compared to TAH,LAVH results in shorter hospital stay and fewer postoperative complications. It is a feasible and safe treatment for large uterus.

Objective To investigate the relationship of plasma brain natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels with the severity of heart dysfunction in elderly patients with heart failure. Methods BNP levels were measured by immunofluorescence in 106 hospitalized patients with heart failure, while NT-proBNP levels were measured by electrochemiluminescence immunoassay in 48 patients. The severity of heart dysfunction was determined by NYHA classification. The left ventricular ejection fraction (LVEF) measured by Color Doppler Ultrasound was used to show the left ventricular systolic function. Results In patients with BNP≤400 ng/L versus BNP>400 ng/L, the rates of LVEF≤45% were 16.4% versus 46.8% (χ~2= 13. 93, P=0. 001), the rates of E/A<1 were 62.3% versus 40. 4% (χ~2 =22. 19,P = 0.024) and the rates of Cr>107 μmol/L were 13.1% versus 38.3% (χ~2 = 11. 31, P = 0. 002) . In patients with NT-proBNP≤400 ng/L versus NT-proBNP>400 ng/L, the rates of LVEF≤45% were 25. 0% versus 58. 3% (χ~2 = 10. 00,P = 0. 019) and the rates of Cr>107 μmol/L were 20. 8% versus 50.0% (χ~2=8. 50,P = 0. 035). Conclusions BNP or NT-proBNP levels increase significantly along the deterioration of the heart failure severity, and it may be important to use BNP or NT-proBNP to predict left ventricular function.
