Objective To explore the role of CGRP and progesterone along with it on the etiopathology of PIH. Methods 8 specimens of umbilical vein endothelial cells from women with PIH were cultured. Four groups were divided when cultured cells were confluent: the sera of normal pregnancy women (group 1), the sera of women with PIH (group2), the mixture of the sera of women with PIH and the injection of progesterone (group3), and the same amount of media (group 4). The cultured cell were added respectively into the four different kinds of media. After 24h of incubation, the concentration of endothelin (ET) and CGRP in media were measured by radioimmunoassay. Results 1. Comparing with group1, the concentration of CGRP in group 2 decreased and ET increased significantly. Statistic difference of ET/CGRP was found between the two groups. 2. Comparing with group 1, the concentration of CGRP in group 3 was unchanged and ET increased obviously. No difference of ET/CGRP was shown between them. 3. Comparing with group 3, in group 2, the concentration of CGRP decreased obviously and that of ET unchanged. Significant difference of ET/CGRP was found. Conclusions Progesterone, along with CGRP, might delay the onset and progressing of PIH.

Many specific therapeutic antibody drugs have been developed for different indications. In drug development, it has been found that the antibody isotype framework can not only affect the physical and chemical properties of therapeutic antibodies, but also influence the activity and therapeutic effect. As a result, IgG isotype selection should be considered carefully in antibody drug development strategies. Because of the unique biological characteristics, IgG4 isotype has been used in some therapeutic antibodies for which effector functions are not desired. In order to provide new ideas for the development of antibody drugs, the research and application progress of IgG4 isotype in therapeutic antibody drug development has been reviewed.

Objective To evaluate the contrast enhanced CT manifestations of lymphoma involving cervical lymph node and to compare with features of metastatic squamous cell carcinoma. Methods CT findings of cervical lymph node were reviewed in 56 patients (male 44, female 12; age: 9-75 year, median 42 year) with untreated lymphoma and 66 patients (male 51, female 15; age: 16-76 year, median 48 year) with squamous cell carcinoma. Four patterns of enhanced nodes were identified: Type I: homogeneous enhancement with an attenuation equal or similar to that of muscle. Type Ⅱ: heterogeneous enhancement with an attenuation much higher than that of muscle. Type Ⅲ: central low density with peripheral enhancement. The enhanced rim was thick and irregular (ⅢA), or thin and regular (ⅢB). Type Ⅳ: central soft tissue density with a very thin enhanced capsule. Results There were various manifestations of cervical nodes of malignant lymphoma, more than one type of abnormalities could be found simultaneously. Type I(47/56, 83.9%) and Type Ⅳ(15/56, 26 8%) were almost exclusively found in lymphoma. Type Ⅱ was more commonly seen in squamous cell carcinoma (31/66, 47%), but was rarely seen in lymphoma (8/56, 14 3%). Type Ⅲ can be seen in both of these disease entities (lymphoma 21/56, 37 5%; squamous cell carcinoma 52/66, 78 8%) , but was more common in squamous cell carcinoma ( P

Objective To analyze the change of surgical route and range of hysterectomy in the past 10 years.Methods From January 2000 to December 2010,the clinical data of patients with hysterectomy were analyzed retrospectively,including clinical features,surgical path and scope of operation.Results There were 1980 patients.The predominant reason for hysterectomy was leiomyomas (52.88％,1047/1980),adenomyosis (17.78％,352/1980),cervical intraepithelial neoplasia (12.17％,241/1980).The age of the patients with hysterectomy for abdominal,transvaginal and laparoscopic was (46.54 ± 7.35),(58.73 ± 10.49),(44.10 ±5.12) years.In 2000-2005,the proportion of abdominal,transvaginal and laparoscopic proportion were 81.78％ (615/752),8.64％ (65/752) and 9.57％ (72/752).In 2006-2010 were 64.50％ (792/1228),6.51％ (80/1228) and 28.99％ (356/1228).In 2006-2010,the proportion of abdominal significantly decreased and laparoscopic significantly rised compared with those in 2000-2005,there were statistically significant differences (P ＜ 0.01).In 2000-2005,unilateral and bilateral annex removal ratios were 15.43％ (116/752),12.23％ (92/752),in 2006-2010 were 8.63％ (106/1228),7.49％(92/1228).Unilateral and bilateral annex removal ratios in 2006-2010 were significantly lower than those in 2000-2005,there were statistically significant differences (P ＜ 0.01 or ＜ 0.05).Conclusions Over the past 10 years,hysterectomy route and range changed with the percentage of laparoscopic increasing,and concomitant unilateral or bilateral annex removal decreased.

Objective To study the influence of spinal instability after lamina decompression in symptoms and progno?sis. Methods The 76 patients were followed up for a minimum of 4 more years. The patients were divided into instability group (n=27) and non-instability (n=49) group according to the X-ray result of the final follow-up. The visual analogue scale (VAS) score, JOA score and improvement rate were compared between two groups at preoperation, 3-month after operation and the final follow-up. Results There were no significant differences in gender, age and mean follow-up time between two groups. There were no significant differences in VAS and JOA scores before surgery, 3-month after surgery and final follow-up between two groups. Postoperative VAS score decreased and JOA score increased with the increase in follow-up time (P<0.05). There were no significant differences in improvement rate [(80.0±8.8)%vs (83.6±11.7)%] and improvement ratio [81.48%(22/27) vs 61.22%(30/49)] between two groups (P > 0.05). Conclusion Although some patients show instability even with lumbar spondylolisthesis after lamina decompression on radiograph,which is no correlation with improvement of symptoms. With appropriate indications, lamina decompression is a simple and effective surgical method,which also retains the spinal movement function.

Objective To evaluate the effects of malignant ascites on the morphological characteristics and the proliferation and migration abilities of the tumor cell and ovarian cancer cell lines(SKOV3)in the ovarian cancerous ascites.Methods Tumor cells extracted from the ovarian cancerous ascites were cultured in vitro with DMEM high glucose culture medium,and ovarian cancer cell lines( SKOV3) were cultured in DMEM high glucose and DMEM high glucose with different proportion of malignant ascites.The morphological characteristics of the cells were observed by optical microscope and electron microscope respectively.Cell proliferation ability was de-tected by CCK kit;The effect of SKOV3 on the migration of ovarian cancer cell lines was measured by scratch test.Results The morphological characteristics of tumor cells and ovarian cancer cell lines( SKOV3) in ovarian cancer ascites were significantly different.The proliferation ability of tumor cells was decreased without the asci-tes.The proliferation and migration abilities of SKOV3 cultured in mixed culture medium were significantly im-proved compared with the cells cultured in high glucose medium.Conclusion The change of tumor cell morphol-ogy in ascites benefits its abilities of proliferation and migration.The malignant ascites promote the abilities of pro-liferation and migration of ovarian cancer cell line(SKOV3).

Objective To investigate the prenatal diagnosis and prognosis of fetuses with mild ventriculomegaly in order to provide evidence for clinical consultation and treatment.Methods The data of 116 mothers with fetal ventriculomegaly who received prenatal care in Peking University First Hospital between January 1,2013 and May 31,2015 were retrospectively analyzed.All cases of fetal ventriculomegaly were found by ultrasound screening,and were subsequently diagnosed by ultrasound consultation as mild ventriculomegaly.The results of fetal cerebral MRI and invasive prenatal diagnosis were analyzed and the growth and development of babies were followed up by telephone using the Gesell developmental scale.All data was analyzed by descriptive statistics.Results Of the 88 cases of solitary ventriculomegaly,48 (54.5％) received karyotype analysis or screening,and only one case was found to be abnormal,which was an unbalanced translocation.Of the 83 mothers with normal delivery,only one infant (1.2％) showed retardation of intelligence and motor development.Of the 28 cases of non-solitary ventriculomegaly,17 (60.7％) received karyotype analysis or screening,and no abnormalities were found.Of the 18 mothers with normal delivery,only one infant showed retardation of growth and development,and was found to have brain hypoplasia before delivery by MRI with normal karyotype.Conclusions The rate of abnormal karyotype in mild vetriculomegaly is very low in this study.The width of the lateral ventricles is stable during pregnancy and the prognosis of infants is good.Thus,whether invasive prenatal diagnosis is necessary for all the fetuses with isolated mild ventriculomegaly remains to be confirmed.
