Objective:To detect the expression of EGFR and NF-ΚB and the relationship between the two fac-tors and radiosensitivity in human nasopharyngeal carcinoma. Methods The expression of EGFR and NF-ΚB were detected with immunohistochemical staining SP methods in forty-one patients. The radiotherapy effect was assessed by follow up visit and clinical judgement. All of the forty-one patients were divided into three groups: the complete response group,the partial response(or the stable disease)group and the progressive disease group. Result:The ex-pression of EGFR and NF-ΚB were detected in human nasophaTyngeal carcinoma tissues, which were not in normal ones. EGFR and NF-ΚB were significant difference of the radiosensitivity in nasopharyngeal carcinoma tissues (P< 0. 05). The expression of EGFR and NF-ΚB in the complete response-group and the partial response(or the stable disease)-group were lower than the progressive disease-group(P<0. 05),and there was no significant difference between the complete response-group and the partial response(or the stable disease)-group(P>0. 05). The two factors'expression had negative correlation with radiosensitivity. Conclusion: EGFR and NF-ΚB, as important tar-gets, could predict the radiosensitivity of NPC, which could be helpful for targeting treatment and promote the effect of radiotherapy of NPC.

0.05).In terms fo LVEF,no differences were found between the 2 groups at 1 week after the operation but patients in the TA group showed higher LVEF at 3 months after the operation compared with the NTA group(P

Objective To detect the presence of DEK protein in the tissue and voided urine of patients with bladder urothelial carcinoma ,and an?alyze the relationship between DEK protein and clinical pathological classification of bladder cancer. Methods The expression of DEK protein was examined by immunohistochemistry in 48 bladder cancer tissues and 18 adjacent normal tissues(control group). The presence of DEK protein in voided urine was analyzed by western blot in 28 bladder cancer patients and 6 healthy individuals(control group). Results The positive ex?pression of DEK protein in bladder tumor tissues(73%)is higher than in adjacent normal tissues(33%,P<0.05). The expression of DEK in su?perficial bladder cancer(86%)was found higher than invasive bladder cancer(55%)with significant differences(P<0.05). The expression of DEK in urine samples of bladder cancer patients(0.834)was found higher than control group(0.242,P<0.05);Compared with the DEK expres?sion of control group,the sensitivity of diagnosis of bladder cancer with voided urine could be 82.1%. Conclusion DEK protein positive ex?pressed in tissues and voided urine of patients with bladder urothelial carcinoma. The expression was correlated with pathological classification of bladder cancer. The positive rate of DEK expression in early stage of tumor tissues is higher than late stage. The presence of DEK protein in tissues and voided urine can be considered as a suitable biomarker for bladder cancer potentially.

Rapid diagnosis is an important link in the prevention and control of infectious diseases.Point-of-care testing(POCT)is portable, fast, easy to operate, intelligent and sensitive, which has been widely used in the detection of pathogenic microorganisms of infectious diseases, host biomarkers, microbial drug sensitivity in recent years.It is of great significance for the monitoring and management of disease epidemiology and rational use of antibiotics.This review summarized the application of POCT in the diagnosis and treatment of pediatric infectious diseases.

AIM: To investingate the potential role of apoptosis in the development of acute lung injury(ALI) following limbs ischemia-reperfusion(LIR) in rats and the effects of raurine. METHODS: The model of LIB injury in rats was made. By using TUNEL, electrophoresis, reverse-transcription polymerase chain reaction(RT-PCR) and immunohistochemistry techniques, pulmonary apoptosis, Fas/FasL expressions and Ca~(2+), reactive oxygen species (ROS),the ratio of DNA double chain in tissue were detected in different groups.RESULTS: The rapid appearance of apoptosis in alveolar epithelial cells and pulmonary vascular endothelial cells were observed after LIR in rats. The ratio of DNA double chain decreased and tissue Ca~(2+) increased. The expression of Fas/FasL mRNA and protein was up-regulated in lung tissue of rats after LIR, which was related to the elevation of alveolar epithelial cells and pulmonary vascular endothelial cell apoptosis. Taurine decreased alveolar epithelial cell and pulmonary vascular endothelial cell apoptosis not by down-regulating expression of Fas/FasL system. CONCLUSIONS: These results suggest that the excessive apoptosis and Fas/FasL system expression may play a role in the pathogensis of ALI following LIB in rats, and taurine decreases alveolar epithelial cell and pulmonary vascular endothelial cell apoptosis.

Objective To discusses the efficacy and safety of patent ductus arteriosus sealing for low body weight children. Methods From January 2008 to June 2012 in our hospital,32 cases (male14 and female 18) of PDA babies< 8 kg weight were given transcatheter closure treatment. The enrolled PDA babies aged 6 month-18 months, average (11 ±5.5 months),weighted (7.2 ±0.6) kg,aortic imaging showed the narrowest diameter of PDA was 1 ~ 8 mm (4.6 ±1.7) mm,descending aorta imaging was performed immediately and 30 min after transcatheter closure treatment. Echocardiography and X-ray radiography examination were performed 1 d,1,3, 6 months after treatment. Results 30 cases got successful patent ductus arteriosus sealing,all the successful patients were treated with domestic closer,and 1 case was complicated with the descending aorta stenosis and ventricular septal defect, and was transferred to surgerical treatment. 1 case of PDA gave up patent ductus arteriosus sealing as descending aorta stenosis caused by the closer. 2 cases were found a trace-residual shunt immediately after patent ductus arteriosus sealing. No serious complications were found in all patients during the follow-up period. Conclusions Application of domestic closer in treatment of PDA infants < 8 kg is a safe, effective and simple intervention treatment method with little trauma and fast recovery.

Objective To study the effect of implanted stent or selected operation in patients with acute occlusion of right coronary artery during the emergency coronary arteriongraphy. Methods Forty-three patients with acute occlusion of right coronary artery who underwent the emergency coronary arteriongraphy were divided into two groups: the implanted stent group ( n = 23) during the emergency coronary arteriongraphy and the selected operation group (n =20) during the emergency coronary arteriongraphy . Then we observed the general data, the coronary artery pathological changes, preoperative and postoperative thrombus, the blood flow, remained stenosis and the prognosis. Results The implanted stent group was similar to the control group in general condition, but implanted stent group was significantly different from the control group in the near, intermediate and distal coronary artery pathological changes ( <0.05) . The control group was significantly different from the implanted stent group in the thrombus and slowly blood flow ( <0.05) . After three months, we reviewed coronary arteriongraphy and selected operation, The implanted stent group was significantly different from the control in the remained stenosis and slowly blood flow (<0.05) . But the implanted stent group was similar to the control groug in the thrombus and new proceeding cardiovascular events. Conclusion When thrombus appears in acute occlusion of right coronary artery, we can implant stent during the emergency coronary arteriongraphy if the thrombus is little, or we can select operation after PTCA on the contrary.

Objective To investigate the clinical features and therapeutic strategies of one patient with meningioangiomatosis ( MA ) complicated with intracranial aneurysm formation. Methods The clinical data of one patient with aneurysm-formed MA admitted to the Department of Neurosurgery,the First Affiliated Hospital of Sun Yat-sen University was analyzed retrospectively. The patient received emergency craniotomy and middle cerebral artery aneurysm clipping and evacuation of intracranial hematoma. The meningeal tissue around the aneurysm was taken for pathological examination. Results Microscopy revealed meningeal thickening in the patient with MA accompanied with intracranial aneurysm. Spindle cells around the meninges and perivascular tissue of cortical hyperplasia formed an annular and fence-like structure. The results of immunohistochemistry showed the hyperplastic vessels and perivascular fibroblast like spindle cells diffuse vimentin-positive;the hyperplastic vascular endothelial cells CD99,CD34 were positive;and the residual glial cells in the lesions showed glial fibrillary acidic protein positive. Conclusion MA complicated with intracranial aneurysm is rare. The vascular condition is poor. The shape of aneurysm is irregular,and the risk of bleeding is high. Excise the involved meningeal tissue and clip the aneurysm with microsurgical operation is the resonable treatment.

[Objective] To explore the effect of early treatment of Chinese herbal medicine on the long-term prognosis of acute myocardial infarction (AMI) . [Methods] One hundred and fifty-seven AMI patients were divided into two groups according to the treatment during the hospitalization: 129 patients treated with Chinese herbal medicine and western medicine were in group A, and 28 patients treated with western medicine only were in group B. Statistical analysis of age, sex, infarction location, complications and medical history was made in all of the patients. A follow-up survey was made to investigate the subsistence of the patients and the incidences of all the events (including death and severe cardio-cerebrovascular events) . [Results] With the death as the end event, the survival graph of group A was higher than group B (P=0.1166); when with all the severe events as the end event, the survival graph of group A was still higher ( P=0.048) .[Conclusion] The probability of incidences of severe events including death in group A is lower than that in group B.

Objective To investigate the current situation of maternal self- efficacy of breastfeeding and explore its influencing factors in Zhengzhou. Methods Using the general condition questionnaires, breast feeding self-efficacy scale, perceived social support scale and Edinburgh postnatal depression scale to assess the situation of 180 puerperas by the convenience sampling in one obstetric hospital of Zhengzhou. Results The total score of maternal breast feeding self-efficacy was(114.04 ± 21.57)points.The frequency of delivery, the way of delivery and feeding ways, the average income of family were effected with breastfeeding self-efficacy. The total score of social support was(68.87 ± 10.43) points, the total score of puerperas depression was(7.61 ± 4.25) points.The social support score had positive correlation with breastfeeding self-efficacy(r=0.423, P<0.01). Puerperas depression had negative correlation with breastfeeding self- efficacy(r=- 0.342, P<0.01). Conclusions The maternal breastfeeding level in Zhengzhou was at a lower level. The level of maternal breastfeeding self-efficacy scale was impacted by maternal social support degree, the degree of depression. Measures should be taken to enhance maternal social support degree, reduce the degree of depression, in order to improve the level of maternal breastfeeding self-efficacy.
