1.Value of serum human epididymis protein 4 and cancer antigen 125 markers in prediction of ovarian cancer
Chinese Journal of Postgraduates of Medicine 2011;34(9):7-9
Objective To explore the value of serum human epididymis protein 4 (HE4) and cancer antigen 125 (CA125) in the prediction of ovarian cancer onset risk. Methods Petected the expression of HE4 by enzyme linked immunosorbent assay (ELISA) and CA 125 by electrochemiluminescence (ECL) in serum of 75 samples of ovarian cancer (ovarian cancer group),132 samples of ovarian benign disease (ovarian benign disease group) and 30 samples of healthy women (control group),calculated the sensitivity and specificity of HE4 and CA125 in the prediction of ovarian cancer onset risk,and drew receiver operating characteristic (ROC) curve. Results The expression of serum HE4 and CA125 were both higher in ovarian cancer group than those in ovarian benign disease group and control group (P < 0.05 ). HE4 was a better index in the prediction of ovarian cancer onset risk than CA 125 (ROC area under curve was 0.966 and 0.905 respectively). The expression of HE4 was various in different pathological types,serous ovarian adenocarcinoma had the highest expression of HE4 (100.0% ,42/42). The sensitivity of diagnosing ovarian cancer by HE4 was 86.7%(65/75), 93.3%(70/75) by HE4 combining and/or CA125,there was no significant difference(P>0.05).Conclusion Serum HE4 could be a good index of predicting the onset risk of ovarian cancer,the combination of HE4 and/or CA125 could not increase the sensitivity of prediction of ovarian cancer significantly.

Objective To explore the surface molecule changes of the experimental autoimmune encephalomyelitis (EAE) rat brain vascular endothelial cells. Methods The expressions of vascular cell adhesion molecule\|1(VCAM\|1) and major histocompatibility complex (MHC) class Ⅱ molecules in the EAE rat brain vascular endothelial cells were tested by immunohistochemistry. The level of tumor necrosis factor (TNF) and interferon\|?(IFN\|?) in defferent clinic grade EAE were tested by MTT [3\|(4 5\|dimethythiazol\|zyl)\|2\^5\|diphenyl) tetrazolium bromide] method. Results There were inducible expressions of VCAM\|1 and MHC class Ⅱ molecules in the EAE rat brain vascular endothelial cells compared with control. The sera of EAE rats possessed the activities of TNF and IFN\|?.Conclusion\ In the CNS inflammation, the change surface molecules in the brain vascular endothelial cells may suggest that it plays important roles in EAE pathogenesis.\;[

Developmental dyslexia is a specific learning disability. The cerebral mechanism of development dyslexia is an important topic that has fascinated many researchers. With the introduction of brain imaging in studies of cerebral mechanism of development dyslexia, many achievements have been made. Studies of developmental dyslexia structure image found that development dyslexia showed brain structure abnormal in the parietotemporal region, occipitotemporal cortex, inferior frontal gyrus, and cerebellum et al, manifesting either in one specific area or by the asymmetry of one area; the functional image studies revealed that development dyslexia showed activity abnormal in most regions that proved to display structure abnormality; studies of brain functional connectivity demonstrates that the abnormality of development dyslexia happened not only in the connection between front-back part in one cerebral hemisphere, but also in the connection between the two hemispheres. In addition, some studies indicate Chinese development dyslexia has different brain mechanisms compared to that of alphabetic languages. These findings provide valuable insight for future developmental cerebral mechanisms research and for the expansion of Chinese development dyslexia research.

ObjectiveTo evaluate the clinical effect of ultra pulse CO2 laser in treatment of 32 patients with primary amyloidosis of the skin. Methods64 patients with primary amyloidosis of the skin were selected and randomly divided into two groups,the observation group(32 cases)and the control group(32 cases).The observation group were treated with ultra pulse CO2 laser,and the control group were treated by routine medicine method.Clinical effect were compared between the two groups after twelve weeks therapy. ResultsThe total effective rates of the observation group and the control group were 90.6%,53.2% respectively.There were a significant difference between the two groups(x2 = 11.13,P<0.01).There were some different irritations in two groups after therapy,to give symptomatic treatment could help relieve.The relapse rate in the observation group was significant lower than that in control group after treatment of 3 ~ 6 months(x2 = 9.471,P<0.01). ConclusionUltra pulse CO2 laser therapy of primary amyloidosis of the skin was safe and effective.

Objective To analyze the risk factors for ventilator-associated pneumonia(VAP) in the intensive care unit(ICU) of a hospital,and provide theoretical reference for preventing and controlling VAP.Methods ICU patients receiving mechanical ventilation for more than 48 hours between October 2013 and December 2014 were monitored by targeted monitoring method,risk factors for the occurrence of VAP were analyzed.Results A total of 483 patients received mechanical ventilation for more than 48 hours,76 (15.73%) of whom developed VAP;the overall ventilator days were 5 347 days,incidence of VAP was 14.21 per 1 000 ventilator days.Univariate analysis showed that groups of gender,age,length of hospital stay,and duration of artificial airway were all significantly different,VAP rate in male patients was higher than that in female patients(x2 =9.838,P<0.01);VAP rate was highest in patients aged 41-70 years(x2 =10.242,P<0.01),followed by patients aged≥71 years;VAP rate were relatively higher in patients with longer length of hospital stay and longer duration of artificial airway(x2 =59.533,P<0.01;x2 =74.215,P<0.01,respectively).Conclusion Incidence of VAP in the ICU of this hospital is higher,especially in male patients,patients aged 41-70 years,as well as patients with long length of hospital stay and long duration of artificial airway.

Objective To supply anatomic foundation for TRAM and DIEP flaps breast reconstruction with both sensory innervation and rectus abdominis muscle function preserved. Methods Dissections of T8~T12 nerves in anterior abdominal wall were performed on 9 embalmed female cadavers (18 sides). By reconstructing DIEP flaps in 15 cases, the natures of the intercostal nerves and the relations with deep inferior epigastric perforators were investigated. Results Most intercostal nerves pierced the rectus abdominis muscle in the lateral one third. There were interconnections between muscular branches of segmental nerves. Sensory branches traveling with vascular perforators were divided into medial branch and lateral branch. The mean length of pure sensory nerve was (27.6?12.2)mm. Conclusion It is possible to preserve sensory innervation by coapting lower intercostal nerves to the 4th thoracic nerve in TRAM and DIEP breast reconstruction. Sparing lateral one third of rectus abdominis muscle does not cause denervated atrophy in the rectus abdominis muscle after TRAM breast reconstruction.

Objective:To investigate the soldiers' depression after sea field training and influence factors.Methods:1107 navy men were evaluated by Zung's Self-Rating Depression Scale (SDS) and Eysenck personality questionnaire (EPQ) after field training.Results: The rate of depression in the study group was 25.04%, N score of the soldiers after sea field training was significantly higher than the norm of Chinese army men. Logistic regression analysis revealed that the factors of nervousness, dyscoimesis, medical history during sea field training, restless, introversion, the level of education, living environment before joining in the army, hunger and so on had influenced the level of depression.Conclusion:The total incidence of depression in soldiers after sea field training is higher than the norm of army men. It is associated with stress, personality characteristics, training factors, general malaise, psychological pressure and the level of education.
