Objective To review the experience of surgical management for caustic esophageal stricture and discuss the surgical techniques of transverse colon interposition for esophageal replacement. Methods 106 patients with caustic esophageal stricture were treated surgically. 32 patients underwent colon interposition with colonphargageal anastomosis and others received colon interposition with a cerrical anastomosis. The ascending branch of the left artery of the transverse colon was preserved as the supporting vessel of the interpositioned colon. Results There was no postoperative death. The leakage of cervical anastomosis was observed in 12 patients, anastomosis stenosis in 8 patients, and tracheotomy was performed in 3 patients. All patients were perfectly recovered by the treatment. Conclusion Transverse colon interposition for esophageal reconstruction is an optimal approach in the treatment of caustic esophageal stricture.

Objective To investigate the relationship between thyroid hormone levels and the attack of arrhythmia after thoracic surgery.Methods Information of 44 patients after thoracic surgery form September 2012 to February 2015 in General Hospital of Tianjin Medical University was collected, and divided in to the arrhythmia group and non-arrhythmia group.A retrospective analysis was carried on their ECG, thyroid hormone levels, and physical health, and the parameters were then compared between the two groups.The correlation of triiodothyronine (T3) level and Acute Physiology and Chronic Health Evaluation (APACHE Ⅱ) was analyzed.Results The arrhymia patients' serum T3 and free triiodothyronine (FT3) levels were below normal levels, while the serum T3 and FT3 levels of the non-arrhythmia patients were within normal range, and the differences between the two groups were significant (P＜0.05).No notable change of other thyroid hormones levels and correlation of T3, FT3 and APACHE Ⅱ score were found.Conclusions There is a significant difference between the arrhythmia and non-arrhythmia groups in serum T3 and FT3 levels.Perioperative thyroid hormone replacement therapy is worthy of consideration and trial in the clinical prevention and treatment of arrhythmia and prognostic improvement of patients.

【Objective】 To evaluate the efficacy and safety of plasma-derived human coagulation factor Ⅷ (FⅧ) in the treatment of patients with hemophilia A. 【Methods】 A multi-center and open, SAT(single-arm trials) clinical study was conducted. A total of 54 subjects with hemophilia A were enrolled in 5 research centers. FⅧ was injected according to the subjects' weight, severity of disease and other factors, and the transfusion efficiency of FⅧ activity at 10 min after the first infusion of the first bleeding event was taken as the main efficacy indexes. The improvement scores of bleeding symptoms and signs within 24 h after the first infusion of the first bleeding event were the secondary efficacy indexes. The pathogenic microbial indexes and FⅧ inhibitors were detected on 90(th) and 180(th) day after treatment. 【Results】 The transfusion efficiency of FⅧ activity of 54 subjects at 10 min after the first infusion was 171.9% on average, with median of 169.5%, both higher than the target value of 100%. Within 24 h after the first infusion, the improvement of bleeding symptoms and signs of the subjects were scored, among which 19 cases (35.2%) were "obvious", 35 cases (64.8%) were "good", and the total clinical effective rate reached 100%. Five subjects (9.3%) had six drug-related adverse events. On 90(th) and 180(th) day after treatment, hepatitis B surface antigen, hepatitis C antibody, HIV antibody, treponema pallidum antibody and FⅧ inhibitors were detected, and no negative to positive cases were found. 【Conclusion】 After infusion, the FⅧ preparation can significantly improve the FⅧ activity level in hemophilia A patients in a short period of time, which has high infusion efficiency and can achieve better treatment efficacy, and can also effectively control and relieve bleeding symptoms and signs, with good overall safety.

Objective To investigate the morphological changes, apoptosis and brain-derived neurotrophic factor mRNA(BDNF mRNA)expression in rat conus medullaris induced by cauda equine compression, and to discuss the possible mechanisms. Methods Ninety male SD rats were divided into 3 groups: normal control, sham operation,and cauda equine compressed. The animals were sacrificed and took samples in 30 min, 2 hours,4 hours,8 hours,1 day,3 days,1 week,2 weeks,3 weeks after cauda equine compression model were created. The morphological study concerned with cauda equina and conus medullaris was done under light microscope and transmission electron microscope. TUNEL staining and in situ hybridization staining were used to investigate apoptosis and BDNF mRNA expression changes. The positive cells in 1mm2 were calculated,and the data were disposed through one way analysis of variance. Results Histological observation showed notable alteration of cauda equina and neurons in conus medullaris. The positive cells of TUNEL and BDNF mRNA in situ hybridization staining increased in 8 hours and 4 hours after cauda equina compressed,and both reached the climax in 3days after cauda equina compressed. At the time 3weeks after cauda equine compressed, the positive cells were still much higher than that of the control groups. Conclusion The compression of cauda equina will result in neurons morphological changes and apoptosis in medullary cone,and cause central neuron un-reversible injury. It might be one of the reasons why the prognosis is poor in cauda equina syndrome. Neurons and glial cells may produce BDNF by themselves to survival from cauda equina compression.

The anti-tumor activity of curcumin against androgen-independent prostate cancer cells in vitro and the possible mechanism were investigated. After curcumin treatment, the effect of curcumin on the proliferation of prostate cancer PC-3 cells was assessed by CFSE staining. Flow cytometery (FCM) was performed to analyze the cell cycle and the induction of apoptosis of tumor cells. A luciferase reporter gene assay was used to determine the effects of curcumin on the activities of intracellular NF-κB and AP-1 signaling pathways. The results showed curcumin could effectively inhibit the proliferation of PC-3 cells in vitro (P<0.05). Cells were arrested at G(2)/M phase. After curcumin treatment, the percentage of apoptotic cells was significantly higher than in control group (P<0.05). The results of the luciferase assay revealed that curcumin selectively inhibited the activities of the NF-κB and AP-1 signaling pathways in PC-3 cells significantly. It was suggested that curcumin could exert anti-tumor activity against androgen-independent prostate cancer cells in vitro by inhibiting cellular proliferation and inducing apoptosis, which was probably contributed to the inhibition of transcription factors NF-κB and AP-1.

Objective To validate a new standardized training program for urological surgeons to improve their laparoscopic surgical skills. Methods The laparoscopic surgical training program was carried out by using the traditional mechanical simulators and animal models. Thirty-three trainees participated the urological laparoscopic surgical training program. Initially, the novices were assigned to practise basic laparoscopic skills step by step on the simulator with fixed trocar positions. After a period of basic training, they were allowed to practise on animal models for some particular proce-dures. Results All trainees (33/33, 100.0%) participated were able to perform all basic techniques skillfully and completed laparoscopic anastomosis accurately after the training. The time required for performing the partial nephrectomy, dismembered pyeloplasty and ureteral reimplantation on animal models declined from 64.0±18.4, 127.54±17.5 and 75.84±11.6 min at the beginning to 30.94±3.8, 65.2±7. 5 and 37.7±7.2 min after practicing these procedures 8 times (P<0.01). They could un-derstand the crucial procedures of the laparoseopic surgeries after 6 to 8 special trainings on animal models. Fifteen trainees (15/33, 45.5%) had started to carry out laparoscopic surgeries after-finish- ing the training program. Conclusions Our program enables the participants to improve their techniques in complicated laparoscopic surgeries. The challenging parts of reconstructive laparoscopic surgeries such as laparoscopic dismembered pyeloplasty can be taught by using animal models. This program could be incorpo-rated easily by all urological departments developing a laparoscopie surgical training program.

Objective To investigate the efficacy and the indication and the management of perioperative complications in treatment of infra- kidney abdominal aortic aneurysm (AAA) by using endovascular graft exclusion (EVGE). Methods From April 2006 to September 2008, 24 patients with infra- kidney abdominal aortic aneurysms were diagnosed by contrast-enhanced CT or MRI scan. Vascular access was obtained through the bilateral femoral artery after arteriotomy and stent-graft was deployed into AAA of below the renal artery to occlude the left over cavity of AAA. The stent- graft was extended and anchored to the both side wall of AAA, the blood flow enter into the arteria iliaca communis through the sten't.Results Stent-graft deployment was successfully performed in all the patients. Immediate aortography after the procedure showed no leakage in 20 patients and the type Ⅰ minor leakage in 4 patients. No stent movement or organ and both lower extremities ischemia was found at the early post operative stage in all the patients. Six months after the operation, in all the 24 patients, contrast-enhanced CT scan showed the disappearance of the aneurysm and thrombosis at the level of the stent. Conclusions EVGE is simple,minimally invasive,less complication and quick recovery after operation. Thus it becomes first choice for the treatment of AAA for the elder patients.

Objective To analyze clinicopathologic features of sebaceoma. Methods Clinical, pathologic and immunohistochemical findings from 31 cases of sebaceoma were retrospectively analyzed. The clinicopathologic features of sebaceoma were investigated. Results There were 9 males and 22 females. The patients′ age was 53.90 ± 15.40 years, and the clinical course was 9.41 ± 13.75 years. Sebaceoma predominantly affected the face. The common lesion of sebaceoma was red, yellowish?red, skin?colored or slight brown papules, with no subjective symptoms in most cases. Histopathologically, neoplasms had symmetric structures, and were located in the dermis. Epidermal involvements were found in 9 cases. The neoplasm cells were mainly composed of basaloid cells, a few mature sebocytes and some transition cells. The proportion of mature sebocyts was less than 1%in 26 cases, less than 20%in 2 cases, and 20%-40%in 3 cases. Mitoses were occasionally found in 5 cases. One patient was complicated by eccrine poroma. Varying amounts of ducts were found in all the patients. Immunohistochemical staining showed that epithelial membrane antigen was expressed on ducts and mature sebocytes in all the patients, while epithelial antigen was undetected in any of the patients. Carcinoembryonic antigen, androgen receptor and D2?40 were found in 20, 24 and 28 patients with sebaceoma, respectively. Conclusions The diagnosis of sebaceoma mainly depends on histopathological examination. Combined immunohistochemical detection of epithelial membrane antigen, androgen receptor and D2?40 is beneficial to its differential diagnosis.
