Objective To evaluate the application of totally implantable central venous access ports. Methods A retrospective a-nalysis of 217 cases was made on the application and complication of totally implantable central venous access ports from October 2003 to May 2008. Results Venous access ports, which were connected to central venous system via subclavian vein in 199 cases and jugularis interna vein in 17 cases, were implanted into subcutaneous of chest wall. The success rate of implantation was 99.6% (216/217). The ports worked well in 207 cases (95.8%), and 9 ports (4.2%) were removed due to complications. Associated complications included subclavi-ana arterial puncture in 3 cases (1.4%) and local hematoma in one patient. Ventricular tachycardia occurred in one patient due to catheter was inserted into the right ventricle (0.4%). Five patients had soft tissue infections around ports (2.3%) and the ports were removed in 2 eases due to anti-infections therapy failure. Catheter dislocation happened in 2 cases (0.9%). The catheter obstruction was observed as a complication, which comprised three instances of catheter distortion and three of catheter-associated venous thrombosis, the ports in these six patients were removed (2.8%). The overall complication was 7.8%. Conclusions Totally implantable central venous access ports can provide a long-term and safe intravenous access to patients who need long-term intravenous infusion, especially for cancer patients received chemotherapy. Although the operation is simple, there are some complications and need to be carefully monitored.

Breast-contour preservation(BCP)encompasses all strategies to preserve the contour of the breast following breast-conserving surgery (BCS) and immediate postmastectomy breast reconstruction (IBR). With the continuous advancement of breast surgery, postoperative outcomes and quality of life of breast cancer patients have been significantly improved. Previous studies reported on BCP as a new comprehensive parameter for evaluating outcomes of breast cancer treatment. Based on preoperative comprehensive evaluation of patients′ general condition, characteristic of breast tumor, and breast morphology, individualized surgical strategy is formulated to improve BCP for early-stage breast cancer and improve postoperative outcomes of patients. Combined with the morphological characteristics of Chinese women′s breasts, breast contour can be preserved not only by BCS and IBR, but also by nipple-areola complex-sparing mastectomy in some breast cancer patients, thereby reducing psychosomatic impact as a result of losing breast mound.

Objective To identify the changes of morphological development status on minority students in China from 1985 to 2005. Methods We selected a total of 15 groups of the Chinese minority students as subjects of the study, including Mongolian, Hui, Uygur, Zhuang, Korean, Tibetan, Yao, Li, Qiang, Buyi, Dong, Miao, Tu, Salar, Kirgiz, with data from the Chinese national survey on students' physical fitness and health condition in 1985, 1995, 2000 and 2005. Height, weight and waist of the subjects were calculated and analyzed. Results From 1985 to 2005, the growth and characteristics of height in the Chinese minority students had a similar increase when comparing to the Han students, but with different degrees. However the growth rate was gradually decreasing. The average heights of Kirgiz, Korean, Salar and Mongolian schoolboys aged 18 years old were 170 cm, being 170.91 cm, 170.47 cm, 170.29 cm and 170.27 cm, respectively, which were close to that of the Hart students. Some minority students had a substantial increase of body weight. However, the waist of some minority students decreased. Only a few groups of minority students had increasing waist, such as Mongolian and Korean rural boys, Mongolian, Zhuang, and Korean rural girls, with the growth being 0.101 cm, 0.095 cm, 0.126 cm, 0.163 cm and 0.107 cm, respectively. Uygur, Mongolian, Kirgiz and Korean students had the morphological development similar to Han urban students, especially Uighur boys and girls. Conclusion From 1985 to 2005, The height, weight and waist of Chinese minority students had an overall increase at different degrees. In order to improve the physical fitness of minority students, awareness on nutrition and health education of both students and parents should be strengthened. Surveillance and programs on growth, development and health status of the minority children and adolescents should also be carried out continuously.

ObjectiveTo explore the effects of bone morrow stromal cells (BMSCs) on the neurological behavior of rats with traumatic brain injury (TBI).MethodsTwenty-four SD rats were randomly and equally divided into control group, TBI group and BMSC group. The weight-drop device was adapted to establish the TBI model. The injury severity and its outcome were evaluated by a set of criteria termed neurological severity score (NSS). Brain tissues were harvested at day 14 to observe the survival and migration of the transplanted cells.Bax expression was detected by RT-PCR. Results NSS was (12 ±3 ) points in the TBI group, significantly higher than (7 ± 1 ) points in the BMSC group (P ＜0.05). The transplanted BMSCs could survive and migrate. Moreover, BAX, a crucail apopotosis gene, was down-regulated to 0.9 ±0.1 in the BMSC group, compared with 1.1 ±0.2 in the TBI group (P ＜0.05). ConclusionsBMSC transplantation is available to improve the neurological function, as may be associated with the Bax.

Objective To study the expression of PI3K and MMP-7 in esophageal carcinoma and the rela-tionship between the expression of PI3K and MMP-7 and carcinogenesis and progression of esophageal carcinoma. Methods PI3K and MMP-7 expression were detected in 24 normal esophageal mucosa,94 primary tumor tissues with SP immunohistochemistal method. Results There were significant differences of PI3K and MMP-7 expressions between esophageal carcinoma and normal mucesa epithelium ( all P < 0.01 ) [71.28% (67/94) vs 4.17% ( 1/24 ) and 52.13% (49/94) vs 0% (0/24)]. There were significant correlations between PI3K expression and the degrees of differentiation,invasive depth,clinical staging and the metastasis of lymph node (all P <0.01 ). The positive ex-pression rate of MMP-7 had the relationship with metastasis of lymph node (P < 0.05 ), the degrees of differentiation ( P < 0.05 ) invasive depth ( P < 0.01 ), and clinical staging( P < 0.05 ) . There was a positive relationship between PI3K and MMP-7 expression in this study (r = 0. 232 ,P = 0.025). Conlusions PBK and MMP-7 play an impor-tant roles in carcinogenesis and progression of esophageal carcinoma and can be used as valuable biomarkers to eval-uate biological characteristics in esophageal squamous cell carcinoma.
