[Summary] The paper reported 9 cases of external type cesarean scar pregnancy treated with transvaginal local lesion resection between January 2013 and March 2014 in this hospital .The surgical exposure was established by using vaginal tractors .The cervical front lip was pulled below outwards by using cervical clamp to expose the front vaginal fornix .Hemostatic water was injected into the cervix vaginal clearance (epinephrine 0.5 mg +NS 500 ml).The vaginal mucosa was opened at bladder cervix groove level for entering the bladder cervix clearance .The bladder was seperated upwards and to the side with fingers to expose uterine isthmus lesions . After cutting the thin muscle , the embryos and part of necrotic tissues were extracted for pathological examination .The incision scar around tissues were trimed and a drainage tube was placed in the uterine .A myometrium full-thickness continuous suture was performed with 1-0 absorbable sutures ( paying attention to avoid endometrial tissues ) , and the vaginal wall was continuously sutured with 1-0 absorbable thread .The drainage tube was removed 5 days after operation .The operations were successfully accomplished in all the 9 cases.The average operation time was 65 min (40-90 min), and the average blood lose was 60 ml (40-80 ml).Cervical tube adhesion occurred in 1 case, and no complications were observed in the remaining cases .The average hospitalization time was 7.5 days (5-10 days).The postoperative time of menstruous restoration was 28-40 days.We deem that transvaginal resection of cesarean scar pregnancy lesion is simple and deserves clinical popularization .

When mature adipocytes are subjected to an in vitro dedifferentiation strategy referred to as ceiling culture, these mature adipocytes can revert to dedifferentiated fat (DFAT) cells. DFAT cells have many advantages compared with adipose-derived stem cells (ASCs) and bone marrow mesenchymal stem cells (BMSCs). For example, DFAT cells are homogeneous and could be obtained from donors regardless of their age. Furthermore, DFAT cells also have the same multi-lineage potentials and low immunogenicity as ASCs. As an excellent source of seed cells for tissue engineering and stem cell transplantation, DFAT cells have better prospects in the treatment of many clinical diseases, such as bone defects, neurological diseases, ischemic heart disease and kidney disease. It is necessary to make more intensive studies of DFAT cells. This article summarizes progresses in the immunological characteristics, differentiation ability and potential clinical applications of DFAT cells.

Objective To investigate the current working status and explore the relationship among job stress, job burnout and organizational commitment in ICU nurses. Methods By using cluster random sampling method, 233 nurses from 5 general hospitals were selected to accept investigation by Commitment Questionnaire and Nurses' general situation questionnaire. Results The job stress and job burnout were both significant negatively correlated with organizational commitment (r=-0.33, P<0.01;r=-0.22, P < 0.01).The management issues and interpersonal relationships and decreased personal accomplishment both had significant impact on affective commitment and continuance commitment of ICU nurses (r=0.539, P < 0.01; r=0.387, P < 0.01). The management issues and interpersonal relationships, professional and career issues and emotional exhaustion had significant predictive power on normative commitment(r=0.458,P < 0.01). Conclusion It generally was in a higher level of job stress in ICU nurses, which indicates that hospital mangers should try to eliminate the causes ,assist them to reduce job stress and relieve the job burnout.

Objective To investigate the expressions and correlations of Kiss-1 and matrix metalloproteinases-9 (MMP9) proteins in the colorectal cancer (CRC) tissues of patients with synchronous colorectal liver metastasis (SCRLM),and the association with the clinicopathologic factors and prognosis of patients.Methods The retrospective case-control study was adopted.The clinicopathological data of 96 patients with SCRLM and 69 patients with CRC and no metastasis who were admitted to the Eastern Hepatobiliary Surgery Hospital of the Second Military Medical University from January 2000 to May 2013 were collected.The 96 CRC tissues and 50 adjacent normal tissues (distance from resection margin ≥ 5 cm) were collected from 96 patients with SCRLM,and 69 CRC tissues were collected from 69 patients with CRC and no metastasis.Expressions of Kiss-1 and MMP9 protein were detected by immunohistochemistry (IHC).The follow-up of outpatient examination and telephone interview was performed to detect survival of patients till August 2014.Comparison of count data and correlation between expressions of Kiss-1 or MMP9 protein and clinicopathological factors were analyzed by the chi-square test and Fisher exact probability.Survival curve was drawn using the Kaplan-Meier method,and survival analysis was done using the Log-rank test.Correlation analysis was done by the Pearson correlation.Results Expression of Kiss-1 protein was located in the cytoplasm of tissue cells.The positive expression rates of Kiss-1 protein in CRC tissues of patients with SCRLM and with CRC and no metastasis and in adjacent normal tissues were 24.0％ (23/96),43.5％ (30/69) and 52.0％ (26/50),respectively,with a significant difference among the 3 tissues (x2 =14.307,P ＜ 0.05) and no significant difference between CRC tissues of patients with CRC and no metastasis and patients with SCRLM (x2 =0.845,P ＞ 0.05).The positive expression rate of Kiss-1 protein in CRC tissues of patients with SCRLM was significantly different from that in CRC tissues of patients with CRC and no metastasis and in adjacent normal tissues (x2 =0.702,11.594,P ＜ 0.05).Expression of MMP9 protein was located in the cytoplasm of tissue cells.The positive expression rates of MMP9 protein in CRC tissues of patients with SCRLM and with CRC and no metastasis and in adjacent normal tissues were 67.7 ％ (65/96),62.3 ％ (43/69) and 36.0％ (18/50),respectively,with a significant difference among the 3 tissues (x2=14.203,P ＜0.05) and no significant difference between CRC tissues of patients with CRC and no metastasis and patients with SCRLM (x2=8.038,P ＞ 0.05).The positive expression rate of MMP9 protein in CRC tissues of patients with SCRLM was significantly different from that in CRC tissues of patients with CRC and no metastasis and in adjacent normal tissues (x2 =13.475,13.475,P ＜ 0.05).The positive expression rates of Kiss-1 protein in CRC tissues of patients with SCRLM were 66.7％,21.9％ and 17.6％ in the high-,mederate-and low-differentiated tumor,50.0％,28.6％ and 17.5％ in the muscular layer of tumor invasion,outside of serosa and serosal layer,44.0％ and 16.9％ in patients with and without lymph node metastasis,respectively,showing significant differences among the tumor differentiation degree,depth of tumor invasion and lymph node metastasis (x2=6.546,6.172,7.453,P ＜0.05).The positive expression rates of MMP9 protein in CRC tissues of patients with SCRLM were 25.0％,66.7％ and 76.2％ in the muscular layer of tumor invasion,outside of serosa and serosal layer,44.0％ and 76.1％ in patients with and without lymph node metastasis,respectively,showing significant differences between the depth of tumor invasion and lymph node metastasis (x2 =12.094,8.690,P ＜ 0.05).All the 96 patients with SCRLM were followed up for a median time of 68 months (range,12-176 months).The median overall survival time,median tumor-free survival time,5-year cumulative survival rate and 5-year tumor-free survival rate were 31 months,26 months,69.6％ and 26.1％ in patients with SCRLM and positive expression of Kiss-1 protein and 26 months,19 months,24.7％ and 12.3％ in patients with SCRLM and negative expression of Kiss-1 protein,respectively,showing significant differences between the overall survival and tumor-free survival (x2=16.578,14.436,P ＜ 0.05).The median overall survival time,median tumor-free survival time,5-year cumulative survival rate and 5-year tumor-free survival rate were 31 months,19 months,24.6％ and 12.3％ in patients with SCRLM and positive expression of MMP9 protein and 28 months,16 months,58.1％ and 22.6％ in patients with SCRLM and negative expression of MMP9 protein,respectively,showing significant differences between the overall survival and tumor-free survival (x2=14.073,8.532,P ＜0.05).Of 96 patients with SCRLM,there were 23 patients with positive expression of Kiss-1 protein (10 with positive expression of MMP9 protein and 13 with negative expression of MMP9 protein) and 73 with negative expression of Kiss-1 protein (55 with positive expression of MMP9 protein and 18 with negative expression of MMP9 protein),with a negative correlation between expressions of Kiss-1 protein and MMP9 protein (r =-0.291,P ＜ 0.05).Conclusions The reduced expression of Kiss-1 protein and elevated expression of MMP9 protein are closely associated with invasion and metastasis of CRC and prognosis of patients.A combination detection of Kiss-1 and MMP9 proteins is expected to become a marker for predicting the prognosis of patients with SCRLM based on the negative correlation between them.
