Objective To investigate the role of survivin gene in the pathogenesis of endometriosis (EMs). Methods The expressions of survivin in endometriosis and normal endometrium tissue were determined ; the effects of GnRHa and COX-2 on the expression of survivin mRNA in endometriosis and normal endometrium in vitro and the effects of GnRHa and COX-2 on the apoptosis index in the cultured ectopie endometrial cells were investigated. Re-sults ①The expression of survivin mRNA was higher in patients with endometriosis than that of healthy controls (P <0.01) ,with no cyclical variation. ②GnBHa exerted a dose-dependent suppression of survivin mRNA expres-sion in cultured ectopic endometrioma cells as well as COX-2. The significant suppression was observed at the 100μg/L concentration of GnRHa and at the 40 μmol/L concentration of COX-2. No cooperation was found between them (P > 0.05). Conclusion ①The up-regulation of survivin mRNA expression may reduce the sensitivity of en-dometriotic cells to apeptosis. Elevated expression of survivin mRNA in ectopic endometrium may have important im-plications for the survival and proliferation of the ectopic endometrial tissue.②Both GnRHa and COX-2 can promote apoptosis by inhibiting survivin mRNA expression in ectopic endometrioma cells in vitro.

Objective To study the expressions of matrix metalloproteinase-3 (MMP-3) and osteopontin (OPN) in cervical carcinoma and their relationship with invasion and metastasis. Methods The expression of MMP-3 and OPN were detected in 54 cases of cervical cancer tissues by immunohistochemical SP method. Compared with 15 cases of normal cervical tissues, the relationship was analyzed between both protein expressions and clinical pathology. Results The expression positive rates of MMP-3 and OPN in cervical cancer tissues (70.37 % and 66.7 %, respectively) were significantly higher than those of normal cervical tissues (20 % and 0, respectively), were significantly higher with infiltration depth >1/2 and lymph node metastasis than those with depth≤1/2 and without metastasis , respectively(P <0.05). The expressions of MMP-3 and OPN were related with depth of cervical infiltration and lymph node metastasis of cervical cancer.Expressions between MMP-3 and OPN were significantly positively correlation(r =0.401, P<0.05). Conclusion The expressions of MMP-3 and OPN are correlated with invasion and metastasis of cervical carcinoma.

Objective To summarize the main nursing point and experience of allogeneic small bowel transplantation.Methods One case underwent allogeneic small bowel transplantation in our hospital on the first of December 2010,the nursing measures were summarized.Results The patient passed the operation well-off,and survived the infection phase and repulsion phase in the transplantation ward.Conclusions Valid preoperative evaluation,taking active measures to prevent intraoperative hypothermia and infection,using self-made vacuum pads to prevent pressure sores during operation,are the guarantees for successful operation.

BACKGROUND:With elevated medical levels, limb salvage surgery for limb malignant tumor is valuable day by day. At present, the limb salvage surgery has substituted amputation and becomes mainstream and development direction of present surgical treatment of limb tumors. However, so far, there are no unified surgical indications for proximal femur tumor, which are controversial. OBJECTIVE:To investigate the efficacy of artificial total hip arthroplasty combined with extended resection of tumor sections for proximal femoral bone tumors. METHODS:Patients with proximal femoral bone tumors in the Second Xiangya Hospital of Central South University were selected and divided into control group and observation group, with 30 patients in each group. According to the disease, lesion curettage, aneurysm wal inactivation, autologous and (or) al ogeneic bone, mixed bone graft and bone graft fixation were selected to treat the control group. The observation group patients received extended resection of tumor sections and total hip arthroplasty. The operative time, intraoperative blood loss, hospital stay and joint function of two groups were compared. 2 years later, patients were revisited. Metastasis and recurrence rate, death rate and quality of life of two groups were compared. RESULTS AND CONCLUSION:There was no significant difference in intraoperative blood loss and surgery time between the two groups (P>0.05). However, hospital stay of patients in the observation group was shorter than the control group. The excellent and good rate of recovery of joint function (83%) was higher in the observation group than in the control group (53%). The metastasis and recurrence rate within 2 years after surgery (7%) and death rate (3%) were lower in the observation group than in the control group (30%, 23%). Various indicators of quality of life of patients in the observation group were significantly better than the control group (P<0.05). These results confirmed that artificial total hip arthroplasty in the treatment of proximal femur tumors is safe and effective.

Objective To analyze the clinical effectiveness,safety and significance of treatment with external circular fixator,through the relationship of inducible nitric oxide synthase (iNOS) and bone regeneration to further explore the mechanism of the molecular biology of bone lengthening at the same time.Methods Collected bone defect after tibial shaft fractures secondary infection who were treated with external circular fixator as study group (28 cases),all the cases fixed by external circular fixator,20 healthy volunteers as control group.Study group in different time point measured the levels of serum iNOS content,were compared with the control group.Results All patients were scheduled to reach the extremity lengthening and the bone defect were repaired and healed in study group.The bacterial culture results showed that 18 cases (64.29％,18/28) of resistant Staphylococcus aureus,5 cases (17.86％,5/28) of Hemolytic streptocaccus,2 cases (7.14％,2/28) ofP.aeruginosa,one case (3.57％,1/28) of drug-resistant Enterobacter cloacae,one case(3.57％,1/28) of Staphylococcus epidermidis,one case(3.57％,1/28) of Onion-like aeromonas,the proportion of the former two was significantly higher than other bacteria (P ＜ 0.05).The levels of serum iNOS content 1 d after surgery in study group were increased,compared with control group,difference was no significant (P ＞ 0.05).The levels of serum iNOS content 14 d after surgery,stoped extend,1 d stoped extend,3 d stoped extend in study group were significantly higher than those in control group [(118.8 ± 6.6) U/L vs.(86.4 ± 5.4) U/L,(136.2 ± 8.4) U/L vs.(88.2 ± 3.6) U/L,(132.6 ± 9.0) U/L vs.(87.6 ± 4.8) U/L,(103.8 ± 5.4) U/L vs.(86.4 ± 4.2) U/L] (P ＜ 0.05),there was no significant difference between two groups in other times (P ＞ 0.05).Conclusions External circular fixator for the repair and reconstruction effects in patients with bone defect can achieve the desired therapeutic goal,the higher expression of iNOS may be one of the molecular biological mechanisms of bone lengthening.

The most common clinical manifestations of Hashimoto’s thyroiditis (HT) are goiter and hypothyroidism. The biochemical thyroid function varies quite widely among patients. Anti-TPO antibodies (TPOAbs) are the most sensitive index to screen HT. The thyroid function deteriorates gradually, and the hypothyroidism is the permanent sequeala of HT. The natural history of HT in children and adolescents is not fully known, and monitoring of thyroid function for all patients should be long-term. Children with hypothyroidism should be treated with levothyroxine replacement therapy.
