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.

The general clinical abilities of attending doctors are closely linked with the overall quality of patient care in a hospital. A set of quality standards for ward rounds by attending doctors were formulated in the author's hospital and an intensive evaluation was conducted by the experts team of the results of inspection and assessment. It is suggested that the hospital should tighten the quality control of ward rounds by attending doctors and pay serious attention to various problems that may occur. In particular, the hospital should set strict assessment standards for post qualification for attending doctors and strive to cultivate their clinical abilities after their post assumption. In addition, it should bring their talent into full play on the basis of vigorous management and assessment and discover and correct their shortcomings in ward rounds in a timely manner.

Cervical spondylotic myelopathy is a common and frequently-occurring disease in Orthopaedics, especially with multi-segmental cervical spondylotic myelopathy. There are several pathogenic factors for cervical spondylotic myelopathy. The clinical symptoms are serious, and the imaging manifestations are complex. Most of them are accompanied by serious neurological damage, which seriously affects the quality of life of patients. Furthermore, some patients have serious cervical spinal cord injury symptoms, which endanger their lives after mild trauma. Therefore, early diagnosis, early treatment and surgery are the most effective methods at present, which could effectively eliminate the factors of spinal cord compression and reconstruct the stability of cervical spine function. However, the choice of surgical approach and decompression fusion has always been the focus of debate. The primary purpose of surgery for cervical spondylotic myelopathy is to completely relieve the compression of spinal cord. According to the imaging characteristics of cervical spondylotic myelopathy, it is the key to the success of the operation to determine the decompression and reconstruction of cervical spondylotic myelopathy. Anterior approach can be adopted in patients with the compression factors located in front of the spinal cord, including disc protrusion, mild osteophyte or local ossification posterior longitudinal ligament, less lesion segments, small compression range, cervical kyphosis or local kyphosis deformity, easy resection of compression and sagittal imbalance correction. Decompression fusion can be selected through intervertebral space, subtotal vertebral body resection and mixed decompression for fusion and fixation. In order to retain the active function of cervical vertebrae, artificial disc replacement and fusion can be selected. For patients with the compression factors located in the posterior part of the spinal cord, including ligamentumflavum hypertrophy or ossification, congenital developmental spinal canal stenosis, there are many factors causing compression in front of the spinal cord. The range is larger, the lesion segment is longer. Thus, it is difficult to resect thoroughly in front of the spinal cord with higher risk of anterior surgery. Although the posterior approach is indirect decompression with the help of posterior spinal cord movement, it plays a good role in improving nerve function with fewer complications and relatively higher safety. There are absolute surgical indications and relative indications for two approaches. Combining anterior and posterior surgery has advantages of complete decompression and strong fixation. However, it has the advantages of great trauma and high risk, so it is necessary to apply it in clinical practice. Moreover, no matter how to choose the approach, we should use perfect imaging data combined with clinical symptoms and signs to clarify the pathological factors of spinal cord com pression, the severity of spinal cord injury, the scope of compression and the responsible segment, and formulate an individualized operation plan.

Objective:To explore the diagnostic value of transrectal ultrasound(TRUS)/multiparametric magnetic resonance imaging(mpMRI) fusion targeted biopsy(FTB) for clinically significant prostate cancer(PCa) detection by using both biopsy histopathology and radical prostatectomy histopathology as reference standards.Methods:A total of 303 consecutive patients with suspicious lesions detected by mpMBI and underwent prostate biopsy at Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine between November 2017 to January 2020 were retrospectively analyzed. All the suspicious lesions were sampled by TRUS/mpMRI FTB in addition with standard 12-core systematic biopsy(SB). The clinically significant PCa detection rates by TRUS/mpMRI FTB and SB were compared by using both biopsy histopathology and radical prostatectomy histopathology as reference standards.Results:The diagnosis of PCa was histologically confirmed in 189 of 303 patients, including 178 patients with clinically significant PCa and 11 patients with clinically insignificant PCa. With biopsy histopathology as reference standard, the clinically significant PCa detection rate of TRUS/mpMRI FTB was statistically higher than SB (57.1% vs 45.9%, P<0.001). Among 189 patients with biopsy proven PCa, 80 patients underwent radical prostatectomy, and the radical prostatectomy histopathology confirmed 79 patients with clinically significant PCa.With radical prostatectomy as reference standard, the clinically significant PCa detection rate of TRUS/mpMRI FTB was statistically higher than SB (91.1% vs 74.7%, P<0.001). Conclusions:Compared with SB, MRI/US FTB can offer more accurate sampling of suspicious lesions on mpMRI, and consequently improve the clinically significant PCa detection rate.
