Objective: To evaluate the cyclooxygenase-2 ( COX-2) expression at mRNA and protein levels , as well as its clinical significance, and to study the correlation of COX-2 with angiogenesis, apoptosis and estrogen or progestron receptors. Methods: Forty-one samples of normal endoraetrium tissues and 52 ones of endometrial carcinomas( EC) were collected,together with their corresponding clinical information. RT-PCR was adopted to determine the expression of COX-2 mRNA. Immunohistochemical staining was engaged to evaluate the protein expression of COX-2, VEGF, Bcl-2 and the MVD marked by CD105. And TUNEL was used to count the apoptosis cells. Results: (1) Significantly higher mRNA and protein levels of COX-2 were found in endometrial carcinomas than in normal endometrial tissues ( P＜0.001) . (2) At protein level ,COX-2 expression was related to the grade(P =0.020) , but had nothing to do with the stage, pathological type, depth of myometrium invasion and lymph node metastasis. Neither did the level of COX-2 mRNA with all the factors above. (3)The level of COX-2 mRAN had nothing to do with that of protein(P =0. 125, r =0. 222). (4) The higher the expression of COX-2 protein was, the higher that of VEGF,MVD or Bcl-2 was,and the lower the count of apoptosis cells was P＜0.05. (6)The upregulation of COX-2 protein had no correlation with ER-α and ER-β . But it had positive correlation with PRA and PRB,P was 0.031 and 0.007 .respectively. Conclusion: (1)The expression of COX-2 is significantly higher in EC than in normal endometrium tissue, not only at the mRNA level, but also at protein level. ( 2 ) At protein level, COX-2 expression is related to the grade, but has nothing to do with the stage, pathological type, depth of myometrium invasion and lymph node metastasis. Neither does the level of COX-2 mRNA with all the factors above. (3)The upregulation of COX-2 protein in EC correlates with the increase of VEGF protein and MVD. (4) The upregulation of COX-2 protein in EC correlates with the increase of Bcl-2 protein and the decrease of apoptosis cells. (5)The upregulation of COX-2 protein in EC has no significant correlation with ER expression, but has something to do with the increase of PRA and PRB.

Many studies have demonstrated the presence of increasing newly formed lymphatic vessels in tumour tissue, which is significantly correlated with the invasion of tumours,lymphatic metastasis, prognosis and so on. Re-cently,with the discovery of specific lymphatic endothelial cells markers and the development of novel experiment methods, turnout lymphangiogenesis become the focusing point for researchers. Here we will review what is known a-bout the reasons, molecular mechanisms and inhibitors of lymphangiogenesis in neoplasms.

Objective To evaluate clinical efficacy and electroencephalogram(EEG)changes quantitatively after the ketogenic diet (KD) by single sample entropy (SampEn) in the treatment of infantile spasms (IS),and to learn the quantitative relationship between the clinical efficacy and EEG.Methods Patients diagnosed as IS were enrolled and started KD in Shenzhen Children's Hospital from April 2010 to December 2013.The SampEn of EEG data in these patients before and after treatment with KD were analyzed.Patients were classified as seizure-free group and non-seizure-free group according to the therapeutic responsiveness to KD.The SampEn findings from two groups were compared to explore the effect of KD on EEG and its related factors.Results Among 35 patients,more than 2 months of treatment,10 cases were seizure free,25 cases still had seizures.SampEn was 0.377 ± 0.246 before treatment,and 0.725 ± 0.405 after treatment in all patients,there was significant difference (Z =-4.351,P =0.000).SampEn was 0.342 ± 0.277 before treatment,and 0.929 ± 0.379 after treatment in seizure free group,there was significant difference between 2 groups(Z =-3.371,P =0.001).While SampEn was 0.391 ± 0.237 before treatment,and 0.643 ± 0.393 after treatment in non-seizure free group,there was a significant difference between 2 groups(Z =-3.371,P =0.001).The mental and motor development was improved after KD with improvement rate were 56％ (14/25 cases) and 70％ (7/10 cases),respectively,but there was no statistical difference(P =0.704).Conclusions No matter seizures are controlled or not,KD can increase the complexity of electrical activity in the brain,which was more obvious in the seizure-free group.Intellectual and movement development can be improved in patients with KD.

Although the ketogenic diet(KD) has originally been used to treat epilepsies,plenty of evidence about the efficacy to intractable epilepsy has not accumulated until recently.These epilepsy or epilepsy syndrome include:Dravet syndrome,Doose syndrome,infantile spasms,Angelman syndrome with epilepsy,tuberous sclerosis complex and focal cerebral dysplasia or other structural epilepsy.It is worth paying more attention to the efficacy of KD on cognition,language development and behavior problems.

Objective To explore the experience of nursing the patients with hypoparathyroidism.Methods Five pregnant patients with hypoparathyroidism hospitalized in our hospital during January 2009 to December 2015 were included in the study.The nursing intervention included performance of health care during pregnancy,childbirth and postpartum nursing.Results The thyroid function of the 5 patients became normal after medication and delicate care.All underwent cesarean resection and all the infants were normal in terms of thyroid function.Conclusions Pregnancy combined with hypoparathyroidism is of high risk and harmful for mothers and neonates.So they should be under management of high risk pregnancy.The prenatal,intrapartum and postpartum nursing measures should be implemented to ensure the safety of delivery.

Objective To explore the etiological spectrum of pancytopenia ,in order to improve the diagnostic accuracy . Methods Retrospectively analysed myelogram and clinical data of 196 cases of patients with pancytopenia syndrom .Results The dominant cause of pancytopenia syndrom in 196 cases of patients was hematological diseases (accounted for 68 .9% ) ,including acute leukemia (14 .8% ) ,myelodysplastic syndrome (12 .2% ) ,aplastic anemia(11 .2% ) and immune‐related pancytopenia(10 .2% );while non‐hematologic diseases accounted for 31 .1% ,including connective tissue diseases (10 .7% ) ,chronic liver disease(7 .2% ) and in‐fection(6 .2% ) .Conclusion Etiology of pancytopenia syndrom is complex ,which should be comprehensively analysed with closely contacting clinics ,in order to clarify the cause ,reduce misdiagnosis and missed diagnosis and improve the diagnostic accuracy .

BACKGROUND:Knee cartilage injury is difficult to heal, which is an urgent clinical problem to solve. OBJECTIVE:To summarize the advantages of synovial mesenchymal stem cel s in the treatment of knee cartilage injury. METHODS:A computer-based search of PubMed was performed for articles related to synovial mesenchymal stem cel s for knee cartilage injury using the keywords of“knee joint, cartilage, synovial membrane, tissues, injuries and repair”. A total of 48 articles were retrieved initial y, and 35 articles were included in result analysis. RESULTS AND CONCLUSION:Synovial mesenchymal stem cel s for treatment of knee cartilage injury can achieve more ideal outcomes. Mesenchymal stem cel s inherent in the damaged tissue are the optimal seed cel s for tissue repair.
