ObjectiveTo summarize and investigate the occurrence,clinical features and treatment of cesarean scar pregnancy.Methods33 cases of cesarean scar pregnancy were retrospectively analyzed.Results10 cases of vaginal massive hemorrhage after uterine curettage,9 cases of subtotal hysterectomy,1 case was cured by MTX treatment,13 cases were cured by conservative treatment of uterine curettage after chemotherapy treatment,10 cases of successful uterus-saving by excision of lesion and uterine repair.ConclusionTransvaginal sonography was an important method in diagnosis of cesarean scar pregnancy and,the key to success was to select the appropriate individual treatment according to classification by transvaginal sonography.

Objective To investigate the association between renin-like activity (RA) and angiotensin Ⅱ (AⅡ) and the ovarian hyperstimulation syndrome (OHSS). Methods Blood samples were taken from 42 patients undergoing in vitro fertilization (IVF). According to the ovarian stimulating response, the patients were divided into 4 groups: group Ⅰ, low responders, 7 cases; group Ⅱ, moderate responders, 8 cases; group Ⅲa high responders without using albumin, 7 cases, group Ⅲb, high responders with albumin, 10 cases; group Ⅳ, severe and moderate OHSS, 10 cases. 5 patients for intrauterin insemination with natural cycle as control. Follicular fluid (FF) was collected at oocyte retrieval from 28 IVF patients (including 7 OHSS patients). Fluid from ascites and hydrothorax was obtained from 3 OHSS patients, and peritoneal fluid obtained from 5 infertility patients by laparoscopy and ascitic fluid obtained from 6 ovarian carcinoma patients served as control. RA and AⅡ levels were measured by radioimmunoassay. Results plasma RA and AⅡ levels at mid-luteal phase from OHSS patients [(19.9?19.0)?g?L -1 ?h -1 and (397.0?378.2) ng/L] were significantly higher than those from the other patients ( P

Osteogenic differentiation of mesenchymal stem cells (MSCs) is an important link of bone metabolism and bone repair, the mechanism of which is usually complicated. Recent studies have found that BMP, FGF, Wnt, Hedgehog, NELL1, IGF, Notch and othersignaling molecules are involved in the regulation of osteogenic differentiation of MSCs. These signaling molecules themselves have been shown to have a strong ability to promote osteogenic differentiation. They can activate the corresponding receptors by specific ligands, thus initiating the specific signal transduction pathways in the cell, and finally promote the transcription and translation of the genes related to bone formation. Furthermore, all the signaling pathways form a complex network which regulates and influences the osteogenic differentiation ofMSCs. Further researches on the mechanism of the interaction of these signaling pathways is of great significance in promoting the development of bone tissue engineering and the treatment of bone metabolic diseases.

OBJECTIVE:To provide reference for curriculum setting for postgraduates majoring in Science of Chinese materia medica. METHODS:The curriculum setting for postgraduates majoring in Science of Chinese materia medica was comprehensively analyzed from the aspects of the regional differences and unique differences of curriculum setting and correlation of curriculum set-ting combined with professional interest of students,actual needs of the professional field and relevant circumstances of industry de-velopment. RESULTS & CONCLUSIONS:The curriculum setting exists regional differences and unique differences. It should show positive correlation with professional interest of students,actual needs of the professional field and relevant circumstances of industry development. It needs further exploration and improvement in the construction of curriculum to make it more scientific and systematic,and the curriculum contents should be able to match the training mechanism and pattern for the cultivation of postgradu-ates .

Objective To investigate the factor relateted to the prognosis in HFRS patients with ARF oliguresis stage and the applied chance of hemodiaglysis in HFRS patients. Methods 46 cases of HFRS patients with ARF, with hemodiaglysis applied hospitalized in the department of infectious disease of Luohe centre hospital during 1996 to 2004 were retrospectively investigated and the factor related to the prognosis were analyzed,divided into three groups:successful group,delayed group, died group, and 14 sorts of clinical factors and common lab test items compared. Results Between live groups, the following factors are statistics value,such as the age, platelet,serum albution before HD,frequency of HD and the days of oliguresis stage, the difference of the other factors such as chance of HD,laboratory indicators and complication occuring rate of are no notable. The age of died group is in one′s prime, died in 3 hospitalized days, given HD only 1~2 times,so,chance of HD and days of oliguresis stage were without comparing value,but,the rate of acute complication is 100 percent,the difference is notable.Conclusions The influence of HD time is no notable,and, to prevent acute complication before HD is the key factor relateted to the prognosis.

Objective To survey the status quo of cervical cancer and cervical precancerous lesion among married women age 35 to 55 in Taishan City,Province and to investigate precautions against cervical cancer.Methods By the request of the government,free cervical cancer screening was carried out from 2010 to 2011,26 879 women in 2010 and 23 197 women in 2011 completed the questionnaire and were checked by gynecological examination and thinprep cytologic test(TCT) voluntarily,and women screened positive by TCT accepted the colposcopy-guided biopsy.Results In 2010,2491 cases of screening positive by TCT,accoanted for 9.47％ ;665 cases of cervical intraepithelial neoplasia ( CIN ),incidence rate was 2.47％,35 cases of invasive cervical cancer ( ICC ),incidence rate was 0.13 ％.In 2011,2038 cases of screening positive by TCT,accounted for 8.78 ％ ;314 cases of cervical intraepithelial neoplasia( CIN ),incidence rate was 1.35％,16 cases of ICC,incidence rate was 0.07％.Conclusion Carrying out cervical cancer screening,could detect CIN in time,give treatment of precancerous lesions as soon as possible and prevent cervical cancer.

TrkB was designated as the functional receptor of br ain derived neurotrophic factor． In these study, we investigated the distributi on of trkB-like immunoreactivity(trkB-IR) in spinal cord of adult cats using spe cific antiserum for trkB by immunohistochemistry ABC method． The results were a s following: trkB-IR was mainly distributed in neurons of spinal cord including ventrolateral horn, intermedius are and dorsal horn． 　　 The subcellular localization of positiveproduct was mainly in cytoplasm． Our results provided morphological evidence on the distribution of trkB in spinal cord of adult cats． It indicated the role o f trkB involve in physiological function of spinal cord of adult cat．

OBJECTIVE To improve the management quality by discussing the usage of "Five Regular Methods" in hospital′s Sterilization Supply Center.METHODS The "Five Regular Methods" managment model into the following aspects of quality,service,safety,efficiency,people′s competency and environment was introduced.RESULTS After 6 months implementation of the model the efficiency and quality of service improved significantly.The environment became clean and shiny.Objects were put on their right place. And we realized the right integration in time and space for people,objects and places.CONCLUSIONS The "Five Regular Methods" is a set of perfect guidance for quality management.It is a management system by providing guidance from inside to outside,people to objects,soft ware to hard ware,theory to practice and rules to process.It is a good method for enhancing the service quality from all aspects.
