Objective To assess patient ’ s fallopian tube function after laparoscopic salpingotomy for tubal ectopic pregnancy.Methods We observed the degree of pelvic adhesion and previous tubal patency by laparoscopic secondary exploration. The fallopian tube function were evaluated in 24 cases ( 26 fallopian tubes ) which had experienced laparoscopic salpingotomy. Results There were 4 cases of severe adhesions (16.7%), 4 cases of moderate adhesions (16.7%), 5 cases of mild adhesions (20.8%), and 11 cases of minor adhesions (45.8%).The status of fallopian tubes:tubal rapture and tissue absence were seen in 11 oviducts (42.3%), intact but obviously shortened oviduct with distal hydrops was seen in 11 oviducts (42.3%), and normal oviduct was recorded in 4 oviducts (15.4%).The methylene blue flow test was performed in the 26 tubes, showing 23 (88.5%) occluded and 3(11.5%) patent. Conclusions The fallopian tubes have incomplete shapes after laparoscopic tubal fenestration for ectopic pregnancy in most patients.We confirm that laparoscopic salpingotomy can not preserve the fertility effectively.

Objective To investigate the expression of Shh, Ptch, Smo and Gli1 proteins who belongs to components of Hedgehog signaling pathway, and to explore the relationship between the abnormal activated of Hedgehog signaling path?way with renal clear cell carcinoma (RCCC). Methods Protein expressions were examined by immunohistochemistry in 76 cases of human RCCC and 12 pericarcinomatous tissues. And 10 fresh specimens from cancer tissues and pericarcinoma?tous tissues were used to examine expressions of Shh, Ptch, Smo and Gli1 by Western blotting. Results The expressions of examined proteins were higher in RCCC than that in pericarcinomatous tissue. Shh (52.6%vs 8.3%), Ptch (63.2%vs 16.7%), Smo (44.7%vs 8.3%) and Gli1 (60.5%vs 25.0%). The increased proteins levels were disassociated with age, gender, and tu?morous size in RCCC. But it was significantly correlated with TNM stage of RCCC. The expressions were gradually increased with higher TNM stage of RCCC or more invasive malignancy. Conclusion Hedgehog signaling pathway is highly activated in RCCC. It might be involved in initiation, progression of RCCC, and it might be used as the target for RCCC treatment.

BACKGROUND:A large number of studies have shown that adult stem cels derived from multiple tissues are available to differentiate towards nucleus pulposus-like celsin vitro. It is unclear whether mesenchymal stem cels derived from nucleus pulposus tissues have the ability to differentiate towards nucleus pulposus-like phenotypes induced by transforming growth factor-beta 1. Up to now, there are few reports on the difference between the differentiation ability of mesenchymal stem cels derived from nucleus pulposus tissues and adipose-derived mesenchymal stem cels. OBJECTIVE:To compare the ability of mesenchymal stem cels derived from nucleus pulposus tissues and adipose-derived mesenchymal stem cels differentiating into nucleus pulposus-like cels under induction of transforming growth factor-beta 1. METHODS:The groin fat tissue and the coccygeal spine of rats were taken respectively to isolate and culture mesenchymal stem cels derived from nucleus pulposus tissues and adipose-derived mesenchymal stem cels by mechanical enzyme digestion method. Flow cytometry was employed to detect the expression of CD105, CD90, CD29, CD45, CD44, CD34, and CD24 of both two kinds of stem cels. Mesenchymal stem cels derived from nucleus pulposus tissues and adipose-derived mesenchymal stem cels were divided into complete induction group (complete induction medium with transforming growth factor-beta 1), incomplete induction group (complete induction medium without transforming growth factor-beta 1) and control group(DMEM/F12 containing 10% fetal bovine serum and 100 mg/L penicilin/streptomycin), respectively. After 14 days of culture, real-time PCR was used to detect the expression of colagen type II, Aggrecan and SOX-9 in each group. RESULTS AND CONCLUSION:CD105, CD90, CD29 expressed positively and CD45, CD44, CD34, CD24 negatively in both two kinds of stem cels. After 14 days of induced differentiation, the expressions of colagen type II, Aggrecan and SOX-9 in the two kinds of cels were significantly higher in the complete induction groups than in the control groups (P < 0.05). Under the induction of transforming growth factor-beta 1, the expression of colagen type II, Aggrecan and SOX-9 in mesenchymal stem cels derived from nucleus pulposus tissues was significantly higher than that in adipose-derived mesenchymal stem cels (P < 0.05). These findings suggest that both two kinds of mesenchymal stem cels have the ability to differentiate towards nucleus pulposus-like cels induced by transforming growth factor-beta, and mesenchymal stem cels derived from nucleus pulposus tissues may be more suitable as seed cels for nucleus pulposus tissue engineering research.

Objective To investigate the clinical efficacy,operative essentials and indications of hybrid spinal fusion surgery for cervical spondylotic myelopathy.Methods From August 2008 to December 2011,thirty-eight patients with cervical spondylotic myelopathy underwent hybrid spinal fusion surgery in our hospital.There were 27 males and 11 females,aged from 33 to 70 years (average,51 years).A total of 86 segments were treated (fusion 48 vs.non-fusion 38).Twenty-eight patients underwent a two-level surgery,and ten patients received a three-level surgery.The Japanese Orthopaedic Association (JOA) score and Visual analogue scale (VAS) were used to evaluate pre-and post-operative neurological function and pain,respectively.The pre-and post-operative range of motion of the cervical spine was measured according to Xrays.Moreover,the surgical complications were recorded and analyzed.Results Thirty-seven patients were followed up for 15 to 55 months (average,29.1 months).The improvement of neurological function was obtained in 36 patients.The JOA score was improved from preoperative 10.5±1.57 to 14.3±1.97 at final follow-up,with an improvement rate of 58.46％,and the results were excellent in 16 cases,fair in 20 cases and poor in 1 case.The VAS was improved from preoperative 7.3±1.04 to 3.2±1.41 at final follow-up.The Cobb angle changed from preoperative 25°±3.21°to 20°±2.56°at final follow-up.After operation,the neurological function was not restored in 1 case; hoarseness and bucking occurred in 2 cases; sore throat occurred in 22 cases; anterior displacement of prosthesis (PCM) occurred in 3 cases.Other patients had no complications,such as displacement,loosening and heterotopic ossification.Conclusion In hybrid spinal fusion surgery,the lesions segments are decompressed fully,the severely degenerative segments are fused,and the motion of the non-fusion segments is reserved.As a result,not only the stability of the cervical spine is achieved,but also an obvious improvement of symptoms and a satisfactory short-term efficacy can be obtained.Therefore,this method is an alternative procedure for cervical spondylosis myelopathy.

Objective To investigate the selection of surgery and clinical outcomes of upper cervical injuries.Methods 25 upper cervical injury patients were involved in this retrospective study from November 2011 to June 2014.Including 20 males and 5 females with mean age of 37.1 years old (range,14-55 years old).Individual operation methods were based on the comprehensive evaluation of specific situations including the clinical manifestation,the type of the injuries and the imaging data.HaloVest distraction was applicated before operation.The surgery by anterior approach were performed for 7 patients and posterior approach were performed for 18 patients.Preoperative and postoperative American Spinal Injury Association (ASIA) grade and Functional Independence Measurement (FIM) score were studied to evaluate the nerve functional restoration.Imaging data before and after the operation were contrasted to evaluate the reduction of the fracture,the bone union,the fusion of the bone graft and the condition of the internal fixation.Wilcoxon Singed Rank Test was applied to compare the FIM score between pre-operation and last follow-up.Results 15 patients presented neurological function deficit because of cervical spinal cord compromise.All cases were followed up for 6-35 months (mean 18.2 months),showing good clinical and radiological effects.Solid fusion was obtained in all patients among 3-12 months.The ASIA grade improved by an average of 1.1 (6 months after operation) and 1.2 (12 months after operation).There was significant difference in FIM score between pre-operation and last follow-up.One patient got cerebrospinal fluid leakage.Conservative treatment was implemented with the Trendelenburg position,rehydration fluids and so on.Removal of drainage tube 8 days later when the drainage was less than 30 ml/24 h.No incision infection,cerebrospinal fluid leakage,migration or breakage of internal fixation was observed at the last follow-up.Conclusion The type of upper cervical injuries are complicated,the characteristics of fracture,dislocation and nerve injury in different patients are different.The specific situation should be evaluated comprehensively to make individual operation methods.The success of the operation requires the proficiency of the anatomic basis,the biomechanical characteristics,precise entrance point and direction in operation,appropriate diameter of the screw and suitable depth of the screw road.
