AIM:To explore the histopathological classification and incidence of orbital space-occupying lesions in children in order to provide references for the diagnosis of orbital space-occupying lesions in children.
METHODS:A total of 290 paediatric patients with orbital space - occupying lesions diagnosed by pathological examinations at the Second Hospital of Tianjin Medical University from January 1998 to December 2012 were retrospectively reviewed.
RESULTS:In 290 paediatric patients with orbital space-occupying lesions, venous hemangioma was the most common (58 cases,20. 0%), the other commons were as follows: hemangio lymphangioma, dermid cyst, neurofibroma, optic nerve glioma, rhabdomyo sarcoma and so on. Capillary hemangioma, venous hemangioma, optic nerve glioma had the predominant age incidence. On the other hand, optic nerve glioma, venous hemangioma, rhabdomyosarcoma had the predominant sex incidence.
CONCLUSION: The majority of paediatric patients with orbital space - occupying lesions are congenital and embryonic lesions, the most common of which is venous hemangioma. Some lesions had the predominant age and sex incidence.

Hypopharyngeal cancer is not common and its prognosis is among the worst in head and neck cancer.Radiation therapy is an important choice of treatment,including radiotherapy alone,radiotherapy combined with surgery and radiotherapy combined with chemotherapy.The improvement of radiation therapy improves the prognosis of hypopharyngeal cancer patients,and radiotherapy combined with surgery is the standard treatment for hypopharyngeal cancer.Nowadays,in order to enhance the preserving rates of the organ and faction,radiotherapy combined with chemotherapy is becoming a research hotspot.

Objective To explore the role of hemoglobin (Hb) level in mortality and morbidity of chronic kidney disease (CKD)patients,aiming to give some evidence for therapy of anemia.Methods Randomized,clinical trials (RCTs) were identified by searching Medline,Embase and the Cochrane library.All the analyses were performed using the Revman software available free from the Cochrane collaboration.Results Twenty-three trials involving 10 204 patients were identified.Overall,the high Hb target was associated with increased risk of all-cause mortality (RR=1.10,95％ CI 1.00 to 1.21),hypertension (RR=1.40,95％ CI 1.12 to 1.75),stroke and hospitalization (RR=1.07,95％ CI 1.00 to 1.14) compared with low Hb target (P＜0.05).No significant difference was found in the risks of non-fatal mycardial infarction (RR=1.13,95％ CI 0.79 to 1.62) and renal replacement therapy (RR =1.00,95％ CI 0.85 to 1.18).Conclusions Targeting low Hb target is beneficial to CKD patients based on reduced risk of hypertension,hospitalization,stroke and all-cause mortality.However,no significant difference is found in non-fatal mycardial infarction and renal replacement therapy.

AIM To investgate the changes in the expression of CREB and p-CREB in the cortex of ethanol dependent rats. On other hand, the effects of fluoxetine on these changes were also studied. METHODS Ethanol was administered in drinking water at the concentration of 6% V/V, for 28 d. The expression of CREB and p-CREB in the rat cortex were measured by immunohistochemistry methods. RESULTS It was found that chronic ethanol treatment and its withdrawal did not modify the expression of CREB in the rat cortex. However, the levels of p-CREB in the frontal and piriform cortex of rats were significantly decreased during ethanol withdrawal, and respectively decreased 57.28%?55.84% compared to control rats at 24 h after ethanol withdrawal. When fluoxetine (ip, 10 mg?kg -1) were administried concurrently with ethanol, it can significantly dampen alcohol withdrawal symptoms and antagonize the down-regulation of the phosphorylation of CREB in the frontal and piriform cortex of rats at 24 h after ethanol withdrawal, the expression of p-CREB protein respectively increased 292 58%,128 44% compared with rats intaking ethanol. CONCLUSION CREB may be one of the substance of the signal transduction process for ethanol dependence. Fluoxetine can reverse the decreased p-CREB levels in rat cortex induced by ethanol withdrawal, which may be the part reason of fluoxetine dampening alcohol withdrawal symptoms.

Objective To evaluate the characteristics of echocardiogram in senile degenerative heart valvular disease. Methods The cardiac structure and functional changes of the 166 cases of senile degenerative heart valvular diseases were studed with HP5500(USA) and En Visor color doppler(Philips). Results Simple aortic valve calcification was found in 93 cases(56.0%); simple mitral calcification, 18 cases(10.8%);aortic valve calcification combining mitral calcification, 55 cases,(33.1%);enlarged left atrium 116 cases(69.9%);left ventricular diastolic dysfunction 142 cases(85.5%).Within 136 cases of cardiac valve dysfunction, there was aortic valvular regurgitation in 70 cases(42.2%),stenosis of aortic valve in 23 cases(13.9%),mitral regurgitation in 20 cases(12.2%),mitral stenosis in 8 cases(4.8%),aortic valvular regurgitation combining stenosis in 10 cases(6.0%),mitral regurgitation combining stenosis in 5 cases(3.0%). The highest morbidity in valvular dysfunction was aortic valvular regurgitation(42.2%),the second was aortic valve stenosis(13.9%),the lowest morbidity was mitral stenosis combining insufficiency(3.0%). Enlarged left atrium was in 116 cases(69.9%). Conclusions The senile degenerative heart valvular disease have no specific clinical manifestation. With increasing age,the proportion of complex valve calcification is increased, and the highest is the aortic insufficiency in valvular dysfunction. The proportion of enlarged left atrium is also increased.

Objective:To investigate the current situation of surrogate in China,analyze the reasons,and then provide effective suggestions and countermeasures.Methods:A questionnaire survey was conducted among medical staff and patients in an institution with assisted reproductive technology (ART),combining literature review and sociological research methods such as data maps,to explore and analyze the surrogacy.Results:The number of institutions with ART increased rapidly and its regulation became difficult.More surrogate network was observed in first-tier cities as well as the eastern and southeastern coastal provinces.That respondents agreeing with surrogacy was quite serious in some provinces.The reasons of surrogate were patients' needs,social concepts,weak government supervision,and so on.Conclusions:It should improve the laws of ART,explore long-term supervision mechanism,strengthen the management of internet,shield the information about surrogate,enhance medical ethics education for ART staff,and guide the infertility patients to establish the correct ethical concepts.

?AlM: To observe the changes of corneal topography and astigmatism et al with various duration of closing eyes and sleep;and study the impact of closing eye and sleep causing physiological hypoxia on corneal topography.
? METHODS: Sixteen volunteers were selected ( 32 eyes), 22-33 (26. 19 ± 3. 95) years old, without refractive errors and other eye diseases, as well as never wearing corneal contact lens, including 10 male eyes and 22 female eyes. The main parameters received corneal simulation K value, corneal astigmatism, corneal irregular measure ( ClM ) and the shape factor ( SF ) by Zeiss corneal topographer. They were measured before and after closed eyes 10, 20, 30, 60, 120min; before sleep and after over 6h sleep, they were detected immediately as soon as they opened eyes after 10, 20, 60, 120min.
? RESULTS: During closing eyes, there were no statistical significance on the changes of corneal topography, corneal astigmatism, and SF. After opening eyes and over 6h sleep, there were no statistical significance on the changes of corneal topography, corneal astigmatism, ClM, and SF.
?CONCLUSlON:Closing eyes and sleep don’t injure the cornea substantially, so corneal topography and corneal astigmatism don’t mainly change.
