Objective To investigate the main causes of the missed and delayed diagnosis of endometrial carcinomas.Methods Endometrial carcinoma and missed and delayed diagnosis were used as key words to search in the Chinese National Knowledge Infrastructure and Wanfang Data.Results There were 37 cases with details.Among these,10 cases were caused by false negative D&C (27.0％ of the total);14 cases were caused by misdiagnosis as uterine benign disease (37.8％ of the total);13 cases were caused by the overlooking of the primary symptoms because of the advanced diseases.Conclusions Paying more attention to the symptoms of endometrial carcinomas is necessary to reduce the missed and delayed diagnosis of endometrial carcinoma.

Hemiplegia is a common type of physical disability in children with brain damage. For many kinds of reasons, the outcome of rehabilitation of the affected upper limb is not good enough, especially in the affected hand. Recently, many studies engaged in the modified Constraint-induced Movement Therapy (mCIMT) to explore the child-friendly way of restraint to improve hand function in hemiplegic children, and were summarized in this paper.

Objective To observe the diameters of macular hole and destroyed boundary line between inner and outer segment (IS/OS) of the photoreceptors and the correlation with the visual acuity in patients with idiopathic macular hole(IMH). Methods The clinical data of 39 eyes (37 patients) with IMH were retrospective analyzed. All the patients had undergone the examinations of visual acuity (Snellen chart), intra-acular pressure, ocular fundus (indirect ophthalmoscope), and Fourier-domain optical coherence tomography (FD-OCT) whose speed was 27 000 A scan/s, area was 6.0 mm×6.0 mm, and the mode was 512×128. The diametres of macular hole and destroyed IS/OS, and the correlations with visual acuity were detected. Results The mean IogMAR was 0.99±0. 44 (ranged from 0. 15 to 2.00), the mean diameter of macular holes was (942.0± 348. 4)μm(ranged from 171 to 1491 μm), and the mean diameter of IS/OS disruption was (1870. 35±673.2) μm(range from 463 to 3176 μm). There was a significant correlation among the diameter of the macular hole, the diameter of the IS/OS disruption, and IogMAR in IMH (P= 0. 038, 0. 002, 0. 000). In eyes with closed macular hole after surgery, the IogMAR and the diameter of the IS/OS disruption had a significant decrease. Conclusion Using FD-OCT the photoreceptor changes can be visualized in vivo. The abnormality in the IS-OS boundary line appears to be involved for a much larger area beyond the macular hole itself, and persists there with small size even after the maeular hole closure surgery.

To investigate the expression of cyclooxygenase-2 (COX-2) in ovarian cancer cell lines, RT-PCR and immunocytochemistry were used to detect the expression of COX-2 in 5 ovarian cancer cell lines. The expression of COX-2 mRNA and protein was detected in all 5 cell lines. It is suggested that COX-2 is expressed in ovarian cancer cell lines, which provides a basis for the chemoprevention of ovarian cancer.

Aim To investigate the hippocampal neuronal injury induced by ?-amyloid peptide ( A?) in rats and the candidate contribution of JNK signal transduction pathway to A? toxicity. Methods Rats were bilaterally injected with A?1 -40 into hippocampi CA1 area. The pathological changes,survival and apoptosis,and ultrastructure of hippocampal neurons,as well as p-JNK positive cells were observed by HE staining,Nissl staining,TUNEL staining,immunohistochemistry and transmission electron microscopy,respectively. Results Thepyramidal cells in hippocampus arranged loosely with decreased cell number. The gliacytes significantly proliferated. Significant apoptotic features were observed in CA1 ultrastructure. TUNEL-positive cells and p-JNK-positive cells significantly increased ( P

Objective To investigate the charateristics of pathological changes in hippocampal subregions in rats with epilepsy induced with different doses kainic acid(KA) ,discuss the etiology and pathway of epileptic wave.Methods 30 male Wistar rats were randomly divided into control group,low(0.025 ?g) and high(0.1 ?g) dose KA injection groups with 10 rats each.KA was focally injected into the right amygdala by a glass micropipette connected to an air pressure system to make epilepsy model.The pathological characteristics in hippocampal subregions in rats with epilepsy induced with different doses KA were observed.Results Compared with control group,high dose KA injection mainly caused neuron loss in the CA3 region,while pyramidal and dentate granule cells were evenly distributed with normal shape and size.Low dose KA injection caused severe damage in both CA1 and CA3 regions.Dentate granule cells didn't show any pathological change and neuron loss in low dose injection.Conclusion The pathological changes in hippocampal subregions in rats with epilepsy induced with KA are different with different doses KA,it might be related to the pathway of epileptic wave and the specific properties of hippocampus.

AIM:A new method to rapidly non-destructive quality control Compound Danshen Tablet was developed by portable acousto-optic tunable filter (AOTF)-near infrared (NIR) spectroscopy. METHODS:A portable AOTF-NIR spectrometer was used to test 215 different batches of Compound Danshen Tablet collected from fifty-six pharmaceutical factories. The samples were analyzed by the Unscrambler program using principal component analysis(PCA). Quantitative analytical models invoking the partial least squares (PLS) algorithm simultaneously predicted the contents of four major constituents in Compound Danshen Tablet:salvianolic acid B,tanshinoneⅡA,water extract and alcohol extract. RESULTS:The qualitative analysis models accurately identified the differences between Compound Danshen Tablet and other reference substances. The results of external validation showed by the significant t-test that no significant difference between predictive and the chemical value,RSD was equal to 0. 990 9,0. 991 3,0. 964 0 and 1. 73% ,2. 08% ,3. 32% ,1. 32% ,respectively. CONCLUSION:The method of rapid non-destructive analyzing Compound Danshen Tablet is explored.
