Objective To evaluate the effect of X-ray stereotactic radiotherapy(SRT)with two different methods in curing brain metastases.Methods 41 patients with brain metastases were treated by SRT,including 24 cases by SRT and 17 cases by SRT combined whole brain irradiation.78 lesions in 41 patients fall into two groups:small tumor(3 cm).All patients were followed for 2～19 months after treatment by CT scan.The effect,recurrent and complication were discussed.Results Following SRT,the effect rate was 92.9% in SRT group and 93.7% in SRT combined whole brain irradiation group.The effect rate was 97.4% for small lesions while 90% large lesions.The recurrent rate was much higher in SRT(17%) than that in SRT combined whole brain irradiation group(5.9%),the difference was statistically significant(?

Purpose To study clinical pathological characteristics,margin status and its influencing factors in different type of facial basal cell carcinoma (BCC).Methods The histopathological features,margin status of the first frozen section and influencing factors was retrospectively analyzed,with review of the relevant literature.The primary outcome variable was the rate of initially positive frozen section margins.Multivariable Logistic regression was used to study histologic subtype,surgical margins,tumor size,location and other factors influence on the rate of initially positive frozen section margins.Results The pathological subtype is the major risk factor,the infiltrative (OR =4.463,95％ CI =1.919-10.380,P ＜0.05) and morpheaform (OR=5.018,95％CI=2.025-16.623,P＜0.05) had higher risk on positive surgical margin compared with the nodular.The rate of initially positive frozen section margins of nodular and superficial BCC at different margins were observed but the difference were not significant (P ＞ 0.05).Conclusion The pathological subtype is the major risk factor.Surgical excision with a 3 mm margin can achieve ideal results for nodular and superficial BCC in facial area.

Objective To explore a new surgical treatment for severe inverted nipple and to reduce the possibility of recurrence. Methods Two opposite long six-side polygon de-epithelialized areas were designed within the range of areola on both sides of the nipple. The four sides in lateral portion were dissected and two wedge-shaped dermal and glandular tissue flaps were created, completely releasing the contractive fiber causing nipple retraction while reserving breast ducts. The flaps were reversed 180 degrees through the tunnel bilateral sides of breast ducts to support the nipple. It was tracted for 3-4 weeks by series 7 needle penetrating the nipple basis. Results All the 14 patients were followed up for 3-18 months, and they were satisfied with the appearance and the aesthesia of the nipple and no recurrence was observed, breast-feed function reserved in 2 cases after childbirth. Conclusions This operation is easy to perform with satisfying aesthetic outcome and breast-feed function remaining.It is an ideal method for correcting serious inverted nipple.

Objective To evaluate medical chemistry adhesive in tension-free herniorrhaphy for inguinal hernia. Methods In this study, 100 patients with primary unilateral inguinal hernia were assigned to study group ( n = 50) and control group ( n = 50) during Jun. 2009 and Dec. 2009. Medical chemistry adhesive (n-butyl-2-cyanoacrylate, NBCA) was used in Lichtenstein tension-free hernia repair in study group and suture procedure was used in control group. Patient demographics, operation time,postoperative length of stay, visual analogue scale ( VAS ) score 24 hours after surgery, incidence of postoperative chronic pain and hematoma, recurrence rate, and other complications were compared between the two groups. Results The duration of follow-up ranged from 12 months to 18 months. There were no recurrences or wound infection in the two groups. In study group, no patient complained of chronic pain postoperatively, whereas in the control group, 6 patients ( 12% ) had a significant chronic pain. In study group, 2 patients (4%) had local hematoma after operation, whereas there were 8 ( 16% ) in the control group ( P ＜ 0. 05 ). There were no significant differences between the 2 groups in postoperative length of stay ( P ＞ 0. 05 ), but the operation time and postoperative VAS score in study group ( 38 ± 5 min and 2. 5 ± 0. 6)were lower than in the control group (42 ± 5 min and 2. 8 ± 0. 8 ), ( P ＜ 0. 05 ). Conclusions Application of medical chemistry adhesive in tension-free herniorrhaphy for inguinal hernia is associated with less postoperative pain, lower incidence of hematoma, less postoperative chronic pain and shorter operation time.

OBJECTIVETo investigate the treatment for tibial exposure wounds.

METHODS39 patients with tibial exposure wounds were divided into three groups according to the exposure location (upper, medium and below). The local muscular flaps were designed to cover the tibial exposure, followed by skin grafts and VSD. VSD was removed one week later.

RESULTSAll the muscular flap and skin graft survived. Mild epidermis erosion happened in 2 cases, which healed spontaneously after dressing. The patients were followed up for 3-6 months with good healing and no walking malfunction.

CONCLUSIONSThe local muscular flap combined with skin graft and VSD is a simple and effective method for tibial exposure wound with short healing time and high successful rate.

Objective To study the characteristics of plasma adiponectin levels exhibiting in gestation women and newborns, as well as the relationships between adiponectin levels and fetal birth weight. Methods Totally 98 subjects have been considered in this study, in-cluding venous blood samples of 36 healthy non-pregnant women (control group), 31 uncomplicated pregnant women (pregnancies group) and the cord blood samples taken at delivery of their singleton infants born at term (newborns group). The concentrations of adiponectin and insulin were determined by radioimmunoassay technique. And SPSS was used for statistical analyses. Results The adiponectin level in women of late period of gestation (WLPG) (11.10±5.72)g/ml was lower than that of other two groups, and the newborns average cord plasma level of adiponectin was (30.71±12.77) g/ml significantly higher than that of the control group (16.52±6.87) g/ml. The adipone-ctin level for WLPG was correlated with FINS and HOMA-IR (r = -0.411, -0.393, P <0.05). The adiponectin level in cord plasma was positively correlated with birth weight(r = 0.416, P < 0.05). The adiponectin level in WLPG was correlated neither with the adiponec-tin level nor body weights of their newborns. Conclusions The average cord plasma adiponectin level of newboms is significantly higher than that of the control group and WLPG. It is positively correlated with birth weight, which suggests that adiponectin may be involved in reg-ulating fetal growth. The adiponectin level in WLPG is correlated neither with the adiponectin level nor body weights of their newborns.
