Objective:The short term results of laparoscopic radical hysterectomy and pelvic lymph nodes dissection for early uterine malignancy were investigated.Methods:70 patients with eady malignant uterine tumor who underwent a laparoscopic radical hysterectomy and pelvic lymph nodes dissection(TLRH+LPL)were retrospectively reviewed.At the samt time,48 patients were recruited to be the control group who had laparotomy radical hysterectomy and pelvic lymph nodes dissection(ARH+APL).Intraoperative and postoperative situations and complications between these two groups were analyzed.Results:70 patients underwent laparoscopic operation,but two cases changed to laparotomy(transfer rate 2.9%).The mean operation time,blood loss,number of dissected pelvic lymph nodes and postoperative temperature recovery time of TLRH+LPL group was significantly different from ARH+APL group(P<0.01),while there were no difference between these two groups on bladder function recovery time and occurance of postoperative complications.Conclusions:TLRH+LPL has the same feasibility and safety with ARH+APL,less invasive to the tissue,thus offers a good option of microinvasive therapy for female malignant tumor.

To investigate the efficacy and the clinical value of total laparoscopic radical hysterectomy (TLRH) for the treatment of uterine malignancies, we performed a retrospective review of 87 patients with cervical cancer and 23 patients with endometrial carcinoma who underwent TLRH at Union hospital between June 2008 and September 2009. Data collected included operative time, estimated blood loss, lymph node count, time for the recovery of normal temperature and time to resumption of normal bladder function, intraoperative and postoperative complications. The procedure was completed laparoscopically in 108 patients. Two patients were converted to laparotomy due to common iliac vein injury. The mean overall operative time was 200.6+/-38.6 min; the mean operative blood loss was 280.5+/-128.3 mL; he mean number of pelvic lymph nodes that were resected wa26. 0+/-5.8. The time for recovery of normal temperature and the normal bladder function after the operation was 5.8+/-2.9 d and 15.2+/-4.3 d. There were 2 (1.8%) common iliac vein injuries during the operation and 10 (9.1%) bladder retentions post operation. It was concluded that TLRH is feasible, minimally invasive and provides promise for the treatment of uterine malignancies.

Purpose：To determine the treatments and prognostic predictors of malignant melanoma of the head and neck. Methods：Surgical treatment and outcome was analyzed for 28 patients with malignant melanoma of the head and neck at department of the head and neck of our hospital (1984-1994). Results：23 patients underwent local excised as the first treatment, and local recurrence was demonstrated in 8 (34.8%). Margin of resection of primary melanoma was divided into narrow excision (≤2 cm) and wide excision (＞2 cm), and 5-year survival was 58% and 40%(P＜0.01). According to surgical methods, 5-year survival of WE, WE/END and WE/TLND were 80%, 80% and 39%. Conclusions：An excision with 2 cm margin is safe procedure for primary tumor of malignant melanoma of the head and neck. Neck dissection may not be practiced until neck lymph node is positive. Neck dissections differ from the positions of the primary tumors, and the flaps must be raised preferably superficial to the platysma.

Objective　The conditional hierarchical clustering for 1-dimensional(1-d) ordinal data was discussed.Methods　Because the individuals are ordered in 1-d,the conditional matrix was constructed with all elements in the second-diagonal are 1 and the others are 0.Distance matrix of individuals defined by some particular definition.Then the conditional-distance matrix was made for the hierarchical clustering by connecting the conditional matrix and distance matrix.This method was called 1-dimentsional conditional hierarchical clustering.An example was illustrated by this method and a Monte Carol study showed that method was feasible and robust.Results　Compared with the least-squares partition,this method is easy to understand,easy to practice and easy to compute.It also can give us a stable result.Conclusion　Because of the austere theory,the simple thought and the convenient application,it's a good method for the 1-d ordinal data.

Objective To explore the related factors that affect the incidence of uterine fibroids to provide a theoretical basis for the clinical diagnosis and prevention.Methods Based on the clinical data selected from June 2014 to July 2016 in pathology of our hospital,159 cases of patients were confirmed with uterine fibroids,a comparative study was employed and the single factor test and the logistic regression analysis were both used to analyze the related risk factors that affecting the incidence of uterine fibroids.Results There were all significant level (P ＜ 0.05) between case and control groups in 40 years to 50 years,the number of abortions (≥2) as well as gynecological diseases,which were the independent factors for the incidence of uterine fibroids.In the present,the regression coefficients of former two factors were 0.186 (P ＜ O.05),and 0.584 (P ＜ 0.05),respectively.The corresponding regression coefficients of breast hyperplasia,vaginitis,cervicitis,endometritis and pelvic inflammatory disease,and other gynecological diseases and gynecological diseases were 0.221 (P ＜ 0.05),O.363 (P ＜ 0.05),O.539 (P ＜ 0.05),0.361 (P ＜ 0.05),and 0338 (P ＜ 0.05),respectively.It suggests that these were independent factors affecting the incidence of uterine fibroids.Conclusions The more the increasing age and the number of abortions,kinds of gynecological diseases infected will increase the risk of patients suffering from uterine fibroids.

BACKGROUND: Basic fibroblast growth factor (BFGF) widely in human tissue participates in trauma repair of various tissues and is one of wound healing factors in the body. OBJECTIVE: To summarize the progress of BFGF in the fracture healing. RETRIEVAL STRATEGY: A computer-based online search of Pubmed Database was undertaken to identify the relevant articles on BFGF in the fracture healing published from January 2000 to December 2007 with the Keywords of "fibroblast growth factor 2 (basic fibroblast growth factor), fracture healing, regulation, signal transduction" in English. At the same time, Chinese relevant articles were searched in China Journal Full-text Database (CJFD) and Wanfang Database published between January 2000 and December 2007 with the same key words in Chinese. Exclusive criteria included articles with repetitive research and non-original study. LITERATURE EVALUATION: A total of 33 articles were collected about the distribution (3 articles), biological characteristics (3 articles) and the effect on the healing of bone fracture (27 articles) of BFGF. DATA SYNTHESIS: Bone healing is the process of regeneration after bone injury and the process of bone formation. BFGF can promote the cell migration by its chemotaxis and accelerate the healing by aggregating mesenchymal stem cells, macrophage and fibroblasts towards trauma region. Present animal studies on BFGF are deep and reports on clinical application are a few. Thus, the effect of BFGF is available. BGFG can affect bone formation by adjusting cell prolifeation and differentiation and changing the synthesis of cell products. BGFG not only can promote the bone growth, but also enhance the adhesion of osteoblasts and scaffold. CONCLUSION: The distribution and biological characteristics of BGFG have been recognized primarily. The further study on modulatory mechanism in the fracture healing of BFGF is carrying through. The bone restoration compounded by BFGF and its carriers is in the experiment and needs to be studied further.
