Objective:The clinical efficacy, safety and quality of life in female patients with stress urinary incontinence (SUI)treated by midurethral sling were studied by multicenter retrospective study.Methods:From January 2018 to December 2018, 531 female patients with severe stress urinary incontinence from seven domestic urinary center were included in this study, including 78 cases from General Hospital of Central Theater Command, 122 cases from Shanghai Jiao tong University School of Medicine Affiliated Ren Ji Hospital, 67 cases from Shanghai Jiaotong University Affiliated First People’s Hospital, 68 cases from People’s Hospital of Jiangsu Province, 71 cases from The First Affiliated Hospital of Xi’an Jiaotong University, 65 cases from Zhejiang Provincial People’s hospital, 60 cases from Xiamen University First Affiliated Hospital. Among the 531 patients, 214 cases received TVT sling with an average age of (58.14±10.16) years. 181 cases were in postmenopausal(84.6%). The number of births ≥2 times was 89 (41.6%) cases. The score of ICI-Q-SF was 16.00±1.73. There were 166 cases of moderate incontinence (77.6%) and 48 cases of severe incontinence (22.4%). There were 317 patients in the TOT/TVT-O group with an average age of (58.33±10.25) years. 247 cases were in postmenopausal(77.9%). The number of births ≥2 times was 120 (37.8%) cases. The score of ICI-Q-SF was 15.79±1.75. There were 256 cases of moderate incontinence (80.8%) and 61 cases of severe incontinence (19.2%). There was no statistically significant difference in general data parameters between the two groups ( P>0.05). 1, 6, 12 months after the operation, the two groups of patients incontinence questionnaire Summary(ICI-Q-SF), common complications and Patient Global Impression of Improvement(PGI-I), satisfaction evaluation follow-up. ICI-Q-SF score improved > by 50% (cure + significant improvement) and 1-hour pad test <10 g (qualitative index) were used as the evaluation index of surgical success. Result:Both of the two surgical methods have high successive rate. There was no significant difference between 94.9% (203/214) of the TVT group and 93.7% (297/317) of the TOT/ TVT-O group ( P>0.05). Postoperative improvement of urinary incontinence (cure rate) [88.3% (189/214)]in the TVT group was slightly higher than that in the TOT/ TVT-O group [77.0% (244/317)] ( P<0.05). There was no change in the recurrence rate of urinary incontinence in the follow-up 6 and 12 months after the operation. There was no statistically significant difference between 4.4% (9/203) in the TVT group and 5.4% (16/297) in the TOT/TVT-O group ( P>0.05). The subjective cure rate 12 months after the operation was 96.3% (206/214) in the TVT group and 95.9% (304/317) in the TOT/TVT-O group ( P>0.05). 10 patients occurred bladder perforation occurred in the TVT group, and no bladder perforation occurred in the TOT/TVT-O group ( P<0.001). The incidence of pain and discomfort in the TVT group was significantly lower at 1.9% than that in the TOT/TVT-O group at 6.9% ( P<0.01). There was no statistically significant difference between the two groups in the incidence of complications such as dysuria/urinary retention, frequent urination/urgency incontinence. Both of them exposed sling ( P>0.05). Conclusion:Both TVT and TOT/TVT-O sling can effectively treat female stress urinary incontinence, and both can improve the sexual satisfaction of patients after the surgery, with fewer complications and other advantages. The selection of specific surgical methods in clinical practice can be individualized according to the patient's physical conditions, clinical needs and the operation methods familiar to doctors.

Objective:To investigate the safety and efficacy of sacral neuromodulation(SNM)therapy for the treatment of lower urinary tract dysfunction(LUTD)in elderly patients.Methods:Clinical data of 91 elderly patients with LUTD from multiple medical institutions who received SNM during the period from January 2012 to December 2016 were retrospectively analyzed.Patients were divided into four groups: the interstitial cystitis(IC)group(n=28), the neurogenic bladder(NB)group(n=36), the overactive bladder syndrome(OAB)group(n=13)and the idiopathic dysuria(ID)group(n=14). Different sets of evaluation parameters were used for different diseases.Patients’ baseline data and data in stage I(test phase)and stage Ⅱ(permanent SNM)were recorded, statistically analyzed and compared.Results:Ninety-one people underwent SNM treatment.Of them, 53 patients received permanent implants(stage Ⅱ), and the total conversion rate of stage I to stage Ⅱ was 58.2%(53/91). Patients receiving permanent implants(stage Ⅱ)had a preoperative period ranging from 3 months to 30 years, and were followed up for 2 to 58 months after treatment, with an average follow-up of 19.6 months.The improvement rates in stage I for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 35.4%, 31.6%, 33.7%, 32.6%, 49.2%, 43.2% and 13.2%, respectively.The improvement rates in stage Ⅱ for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 43.2%, 40.0%, 37.8%, 50.5%, 70.5%, 70.4% and 43.2%, respectively.Three adverse events occurred, including 1 case of recurrent symptoms, 1 case of moderate infection, and 1 case of electrical lead dislocation.Conclusions:Sacral nerve stimulation has definitive and consistent curative effects on LUTD in elderly people.The follow-up time should be extended to further study the safety of sacral nerve stimulation.

Osteochondral defects caused by various factors are still difficult clinical problems. With the development of tissue engineering, the strategies and methods for repairing osteochondral defects in the past decade have made great progress, and some osteochondral tissue stratified stent products have gradually entered the clinical trial stage.. The related articles on tissue engineering for the treatment of osteochondral defects were retrieved by searching databases with key words osteochondral defects, cartilage repair and hierarchical scaffolds. This paper discussed the research status of hierarchical scaffolds in osteochondral tissue engineering during recent five years. In this work, the classification of hierarchical scaffold including monophasic scaffolds, bilayered scaffolds, multilayered scaffolds and gradient scaffolds, are summarized by comparing different experiment researches. Furthermore, the advantages and disadvantages of different types of hierarchical scaffolds were introduced through analyzing relevant studies. Monophasic scaffolds can support the adhesion and proliferation of osteoblasts and chondrocytes, but lack the inherent stratified structure features required for osteochondral regeneration.. Bilayered scaffolds consist of a chondral layer and subchondral layer which base on the biocompatibility of monophasic scaffolds. Biphasic scaffolds are significantly better than monophasic scaffolds in simulating natural cartilage, but the interface between chondral and subchondral layer is poor binding. Compared with bilayered scaffold, trilayered scaffolds are added with an intermediate layer which simulates the calcification of normal cartilage between the two layers, so as to obtain better connection of the bone and cartilage layer. Unlike hierarchical scaffolds, gradient scaffolds provide a gradient connection between the layers, which is more similar to the native osteochondral tissue. In the past five years, the development of osteochondral layered scaffolds mainly depended on the novel structure and fabrication methods of scaffolds. However, correlational clinical studies are quite few. Further high quality and large clinical studies are still required.

Objective To explore the angiogenesis&neovascularization effects of naringin treatment in ovariectomized rats’fracture healing. Methods Upper 1/3 transverse tibial fracture model 4 weeks later after ovariectomized were estimated and randomly divided into the naringin group and control group. Microfil perfusion technique was used to analysis the angiogene?sis situation at two weeks after bone fracture. HE staining was used to evaluate the level of angiogenesis&neovascularization of tis?sue from histological point of view. The relative expression of VEGF in the callus was identified by real?time polymerase chain re?action. Immunohistochemical technique was used to observe the vessel endothelial growth factor?2 in the callus of the two groups. Maximum fracture load was tested by three?point bend test. Results The vascular volume and vascular density were more in nar?ingin group than control group. The HE staining of the 2 week group slices shows that the VA, VN2 of the unit of high magnifica?tion vision of the naringin group was significantly larger compared to the control group. Real?time PCR revealed that the compara?tive expression of VEGF is more in naringin group than in control group; the positive number of VEGFR?2 is more in naringin group than in control group. Naringin can promote the maximum load of the callus. Conclusion Naringin can promote ovariecto?mized rats’angiogenesis&neovascularization in the early process of fracture healing. It may be act on the signaling pathway of VEGF/VEGFR?2.
