Retrospective study was carried out in 93 cases of endometrial carcinoma admitted to our hospital since Jan. 1985 to Dec. 1994. Thirty five cases were older than 60 years, and 24 cases were younger than 50 years. All of the cases had pathological diagnosis and were staged according to FIGO. When compared with the younger group, the rate of older patients with stage Ⅰa was higher (11.4% in younger and 45.4% in older, P

The expression of ZNF191 mRNA in 31 ovarian malignant tumors and 31 normal ovary tissues were investigated by reverse transcription-polymerase chain reaction (RT-PCR). It was found that expression level of ZNF191 mRNA in malignant ovarian tumors was much less than that in normal ovary tissues (P

Objective To propose new policies and strategies that will optimize the transformation of medical research achievements at hospital level.Methods In this paper,we systematically analyzed the characteristics and influencing factors of the transformation of medical research achievements based on the status quo in our hospital.Results In our hospital as an example,major problems in the transformation of medical research achievements identified as low investment,low conversion rate,complex procedures,multi-links existed and more multi disciplinary cooperation needed.Conclusions The hospital can take some measurements to optimize the transformation of medical research achievements,such as more stream lined management of scientific research project,establishing and improve the platform for scientific research transfer,increasing the funding,strengthening cooperation among different disciplinaries,building a professional team to promote the transfer and so on.

A modified dye test with microplate was to be established to detect Toxoplasma antibodies with cell-cultured Toxoplasma gondii. Numbers of stained and unstained tachyzoites were estimated in every 100 tachyzoites in each well after dyeing with methylene blue. The dilution with 50% tachyzoites stained was used as final dilution. Better results of the microplate dye test has been received when the concentration of tachyzoites in suspension reaches 109/ml with 1% sodium citrate as accessory factor.

Objective:To explore the way to separate and culture eutopic and ectopic endometrial glandular cells and their stromal cells,providing an in vitro cell model of endometriosis for study of its mechanism. Methods:Digestion,filtration and sedimentation were used to isolate and culture the eutopic and ectopic endometrial glandular cells and their stromal cells. The estrogen level was imatated to study the way of promoting cell growth. Morphological characters of eutopic and ectopic endometrial cells were examined using optical microscope. Results:The success rate of separation and culture of normal control endometrial glandular cells and its stromal cells was 91.7%(11/12);of eutopic endometrial glandular cells and its stromal cells of endometriosis was 93.8%(15/16);of etopic endometrial glandular cells and its stromal cells of endometriosis was 75.0%(12/16) . Conclusion:The cultured eutopic and ectopic endometrial cells is more like human body feature than the endometriosis model of animals. So the isolation and culture of eutopic and ectopic endometrial glandular cells and their stromal cells may serve as an in vitro experimental model.

Objective To study the MRI manitestation of juvemle acute pure cartilage fracture of the knee joint.Methods The MRI changes of cartilage,subcartilage low signal line and subcartilage bone were analysed retrospectively in 26 juvenile patients with acute pure cartilage fracture confirmed by arthroscopy.Sagittal and coronal MRI scanning were performed in 26 patients.Using fast low angle shot fat saturation T_1-weighted image(FLASH-FS-T_1WI)sequences,spin echo T_1-weighted image(SE-T_1WI)and fast imaging with steady-state precession three dimensional fat saturation T_2-weighted image(FISP-3D-FS- T_2WI)sequences in sagittal plane,SE-T_1WI and multi echo data image combination T_2-weighted imaging (MEDIC or ME-T_2WI)in coronal plane.Using ME-T_2WI sequence,axial plane MRI scanning in 5 patients.Results Twenty-seven sites of 26 patients include 8 patella,7 femoral medial condyle, 11 femoral lateral condyle and 1 tibial plateau.Three types pure cartilage fracture were observed,totally defect of the cartilage in 7 sites(include 3 patella,2 femoral medial condyle,1 femoral lateral condyle and 1 tibial plateau),fissuring fracture in 3 sites(include 2 femoral medial and 1 femoral lateral condyles), superficial defect of the cartilage in 17 sites(include 5 patella,3 femoral medial and 9 femoral lateral condyle).Corpus liberum was found in 21 patients'knee joints by arthroscopy,but only 3 cases by MRI. Bone bruise was detected,and subcartilage low signal lines were normal.Conclusion Using FLASH-FS- T_1WI,SE-T_1WI,FISP-3D-FS-T_2WI and ME-T_2WI sequences,sagittal and coronal MRI scanning in femoral and tibial plateau pure cartilage fractures,and using ME-T_2WI sequence axial scanning in patella r cartilage fractures may show the position,extension and types of the acute pure cartilage fracture of the knee joint. MRI is the hest non-invasive method for studying cartilage fracture.

Objective To investigate the clinical characteristics of infectious diseases of CNS.Methods Inpatients treated in the second hospital of Hebei Medical University from 1996 to 2005 were subjected to retrospective study.Results During 10 years,the hospitalization number of infectious diseases of CNS was 3929.The proportion of inpatients with viral meningitis(encephalitis),cerebral cysticercosis,tuberculous meningitis(TBM),purulent meningitis(PM)and cryptococcal meningitis(CM) was 63.8%,17.4%,7.7%,0.7% respectively.The hospitalization number of viral meningitis (encephalitis),TBM,PM and CM in the 2001—2005 5-year period was 53.5%,21.3%,35.3%,and 77.3% higher than that of the 1996—2000 period.Whereas the hospitalization number of cerebral cysticercosis decreased by 32.4% than that of the last 5 years.The peak months of viral meningitis (encephalitis)in a year were July,August and September.The peak months of TBM in a year were April, May and June.The case fatality of viral meningitis(encephalitis),cerebral cysticercosis,TBM,PM and CM was 8.1%,6.9%,22.4%,12.9%,33.3% respectively.Conclusions In the past l0 years,the incidence of common infectious diseases of CNS has increased in Shijiazhuang except cerebral cysticercoids. Our vigilance should be improved and some effective measures should be adopted to keep away infectious diseases of CNS.

Objective To investigate association between human leukocyte antigen DQB1 (HLADQB1 ) gene polymorphisms and bronchial asthma among Mongolian and Han nationalities. Methods Sequence-specific primer polymerase chain reaction (PCR-SSP) was used to detect frequencies of HLA DQB1 genotypes and alleles in 50 cases of Han and 68 Mongolian asthmatic patients, and 50 Han and 54 Mongolian healthy controls, respectively. Difference in gene frequencies between the two nationalities was estimated by odds ratio (OR) and chi-square test. Results Frequency of the HLA-DQB1 0602 allele was significantly higher in Han patients with bronchial asthma than that in healthy Han nationality (OR = 6.163,P ＜0.01 ). Frequency of the HLA-DQB1 0603/0608 allele decreased in Mongolian asthmatic patients, as compared to that in healthy Mongolians ( OR = 0.199, P ＜ 0.05 ). Frequency of the HLA-DQB1 0301/4 allele was significantly higher in Mongolian asthmatic patients as compared to that in healthy Mongolians ( OR =2.074,P ＜0.05). Frequency of the HLA-DQB1 0301/4 allele was significantly higher in Mongolian than that in Han asthmatic patients ( OR = 2.482 ,P =0.05). Frequency of the HLA- DQB1 0602 allele was significantly higher in healthy Mongolians than that in healthy Han nationality ( OR = 3.341, P ＜ 0.05 ), in contrast, frequency of the HLA-DQB1 0402 allele was significantly lower in healthy Mongolians than that in healthy Han nationality ( OR = 0.209, P ＜ 0.05 ). Conclusions The HLA-DQB1 0603/0608 allele is possibly a protective gene and the HLA-DQB1 0301/4 allele a susceptible gene for bronchial asthma in Mongolians, and the HLA-DQB1 0602 allele is possibly a susceptible gene for bronchial asthma in Han nationlity.

In MAST (mRNA accessible site tagging),the DNA tags from synthesized library were employed for identifying mRNA accessible sites. A large number of tags were amplified and subcloned for sequencing to verify mRNA binding profiles. A PCR was designed by using one primer which bridges over the tag terminal sequences. In PCR reaction DNA tag fragments were concatemerized by a bridge primer in reaction cycles. The concatemerized tag fragments were subcloned and sequenced. Dozens of the concatemerized sequences contained thousands tags. The PCR was a simple,effective way which for sequencing tags in a high through put manner.
