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.

Objective To explore the effect on the neural endocrine and gastro intestinal functions when using Chinese traditional medicine in the treatment after the gyno-pathy operation of the wond's complete cutting off. Methods To compare 86 postoperative cases of gyno-pathy (womb's complete cutting off) being treated partly with Chinese medicine wiht the same 75 cases treated during the same period without Chinese medicine in order to investigate the different effect on the recovery of their neural endocrine and gastric intestinal functions. HZ Results The result shows that the patients in the tested group can recouer quickly while the neural endocrine and the gastro intestinal functions of the opposite group cannot recouer or recover very slowly in a long time. Conclusion Traditional Chinese medicine is rather helpul for the recovery of thd postoperative gyno-pathy patients if it is correctly used .

Objective To detect peripheral blood neutrophil CD64 and procalcitonin(PCT)in children with diarrhea ,and to ex‐plore significance for differential diagnosis of diarrhea in children .Methods A total of 180 cases of children with diarrhea treated in this hospital from July 2012 to May 2014 were selected as subjects ,and were classified into three groups :bacterial diarrhea group (n=60) ,viral diarrhea group(n=60)and non infectious diarrhea group(n=60) .The levels of peripheral blood neutrophil CD64 and PCT were determined in all three groups ,and the diagnostic values of CD64 index and PCT were evaluated .Results The peripheral blood neutrophil CD64 index and level of PCT in the bacterial diarrhea group were significantly higher than those in the viral diar‐rhea group and non infectious diarrhea group ,and the positive rates of CD64 index and PCT in the bacterial diarrhea group were sig‐nificantly higher than those in the viral diarrhea group and non infectious diarrhea group ,all had statistically significant differences (P<0 .05) .The specificity and positive predictive value of CD 64 index in diagnosing bacterial diarrhea were significantly higher than those of PCT ,both had statistically significant differences (P<0 .05) .The relative analysis showed that the CD64 index was positively correlated with level of PCT (r=0 .865 ,P<0 .05) .Conclusion The CD64 index and PCT level of children with bacterial diarrhea increase significantly ,which indicates that the detection of CD64 index and PCT have significant clinical value in early diag‐nosis of bacterial diarrhea .

BACKGROUND:Increasing number of genes and signaling pathways are involved in regulating stem cels periodicaly, and wherein Wnt/β-catenin signaling pathway is an important pathway of stem cels.
OBJECTIVE:To investigate the effects of Wnt/β-catenin signal pathway on mouse endometrial stromal cels.
METHODS:After injection of Wnt/β-catenin pathway inhibitor or activator, endometrial tissues from Balb/c mice were obtained, some of which were used for detection of invasion of endometrial stromal cels and western blot detection, and the rest of which were used for preparing animal models of endometriosis folowed by immunohistochemical detection.
RESULTS AND CONCLUSION:The expression of β-catenin and GSK3β proteins was significantly higher in the activator group than the inhibitor group (P < 0.05). The number of transmembrane cels was significantly higher in the activator group than the inhibitor and control groups (P < 0.05). Immunohistochemical findings showed positive expression of E-cadherin in ectopic endometrial tissues of the inhibitory group, and strongly positive expression of vascular endothelial growth factor in ectopic endometrial tissues of the activator group. These findings indicate that Wnt/β-catenin signaling pathway may cause endometriosis by strengthening ectopic endometrial implantation, invasion and metastasis.

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 discuss the clinical characteristics of advanced schistosomiasis combined with tuberculous pleuri?sy,so as to reduce misdiagnosis and mistreatment. Methods The clinical data of 15 patients suffered from advanced schistoso?miasis combined with tuberculous pleurisy were collected and analyzed retrospectively. Results The 15 patients all showed var?ious degrees of gastrointestinal symptoms with the performance of abdominal distension,digestive function and fatigue,14 pa?tients showed various degrees of edematous,9 patients showed stuffiness,4 patients had cough and expectoration,and 2 pa?tients had low fever and night sweats. Three cases were diagnosed within 2 days after admission,9 cases were diagnosed within one week after admission,and 3 cases were diagnosed after one week. Fifteen patients all received anti?tuberculosis treatment based on routine liver protection,diuresis,and symptomatic and supportive treatment. One patient with severe liver and kidney dysfunction died and one with gastrointestinal bleeding died. The remaining 13 patients were clinically cured. Conclusions The patients suffered from advanced schistosomiasis combined with tuberculous pleurisy do not show obvious tuberculosis poison?ing symptoms,and are easily misdiagnosed and missed?diagnosed. Therefore,physicians should pay much attention to the pa?tients whose pleural effusion cannot subside effectively or whose symptom cannot improve.
