Objective:To investigate the defeat of men undergoing in vitro fertilization and embryo transfer (IVF-ET) and analyze its influencing factors. Methods:A total of 202 male patients undergoing IVF-ET in Reproductive Medicine Hospital in Changsha from May 2021 to September 2021 were selected by random sampling. General data questionnaire, Chinese version of defeat scale, social support scale, Olson marital quality questionnaire (marital satisfaction, communication), self-rating depression scale, mental resilience scale were used.Results:The defeat score of 202 men in IVF-ET was 16.25±9.93. Marital status, marital quality, education, communication, social support, depression and resilience were the main influencing factors of male defeat after IVF-ET (all P<0.05). Conclusion:Male who have received IVF-ET treatment also have a certain degree of defeat. While paying attention to the psychological status of women who have received IVF-ET, we should also pay attention to the psychological health of the male who have high defeat in IVF-ET treatment and carry out targeted psychological intervention measures to alleviate their defeat, which will be beneficial to the treatment outcome.

Objective:To evaluate the feasibility and clinical efficacy of deformed complex vertebral osteotomy (DCVO) technique on the treatment of angular kyphosis of cured spinal tuberculosis.Methods:A retrospective study was performed on patients with angular kyphosis of cured spinal tuberculosis who underwent the DCVO technique or posterior vertebral column resection (PVCR) technique from Jan, 2007 to Jan, 2019. 33 patients were included, 18 males and 15 females, the average age was 39.5±15.0 years old (ranged 9-78 years old). The vertebral deformity in thoracic vertebrae 14 cases, thoracolumbar vertebrae 16 cases, and lumbar vertebrae 3 cases. 20 cases underwent the DCVO technique, while 13 cases underwent PVCR technique. For DCVO group, the multiple malformed vertebrae were considered a malformed complex, and a larger range and angle wedge osteotomy was performed within the complex using the DCVO technique. PVCR technique would resect the whole deformed vertebrae, and subsequently brought the two separated spinal columns together with instruments and titanium mesh. The intro-operative blood loss, operating time and complications were recorded. The radiological measurements included preoperative and postoperative spinopelvic parameters, which including thoracic kyphosis (TK), lumbar lordosis (LL), sagittal vertical axis (SVA), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS) and segmental kyphosis. The recovery of neurological function was evaluated by Frankle classification.Results:All patients were followed up for 7-72 months. Comparing with the cases underwent PVCR technique, the DCVO group has a significantly lower blood loss (1315.00±462.57 ml), operating time (293.00±83.86 min) and complications rate (1.5%). At the time of preoperation, postoperation and last follow-up, the deformity angle of DCVO group was 96.80°±6.32°, 29.10°±6.96°and 29.05°±6.49°, which gained an average 69.9% correction rate. The statistical analysis suggested that deformity angle was enormously corrected. And there was an insignificant difference between DCVO group and PVCR group. Meanwhile, the preoperative, postoperative and follow-up TK of DCVO group was 96.96°±29.13°, 37.15°±4.88° and 37.00°±3.89°respectively, whosecorrection rate was 67.1%; LL was 66.70°±21.21°, 42.25°±5.53° and 41.90°±4.98°, which have a significant difference between pre-operation and post-operation/follow-up ( F=23.997, P<0.001) ; SVA was 75.95±18.63 mm, 16.30±6.88 mm and 16.55±7.30 mm. PI was 47.50°±6.12°, 47.35°±5.54°and 47.90°±5.93°, PT was 37.25°±9.63°, 18.50°±1.99° and 19.00°±1.65°; SS was 10.25°±8.27°, 29.15°±5.91° and 28.85°±5.77°. The sagittal and spinopelvic parameters of two groups improved significantly at postoperation and follow-up. No obviously difference of spinal parameters was found between two groups at preoperation and postoperation. Both groups have cases with dysneuria. And all of these cases achieved different degrees of recovery at follow-up. Conclusion:The use of DCVO technique for the treatment of post-tubercular angular kyphosis is safe and efficiency. DCVO leads a better clinical outcomes and lower complication rate than VCR technique.

BACKGROUND:There are few studies concerning estrogen receptorβgene, and its mechanism of regulating the bone metabolism is stil unclear now. OBJECTIVE:To analyze the effect of estrogen receptorβ(ERβ) silencing on the expressions of transforming growth factorβ1 (TGF-β1) and bone morphogenetic protein 2 (BMP-2) in human osteoblasts METHODS:There were three groups:blank control group (hFOB 1.19 uninfected with any retrovirus);negative control group (containing invalid interference fragment ERβ-shRNA-nc);optimal RNAi group (ERβ-shRNA-3). ERβ-shRNA retroviral vectors in the optimal RNAi group were used to transfect human osteoblasts fol owed by resistance screening and cel expansion. MTT assay was used to detect the proliferative activity of ERβ-silenced osteoblasts. Then under estrogen intervention, the stable inhibition rate of ERβwas determined using western blot assay, and the expressions of TGF-β1 and BMP-2 in human osteoblasts after ERβsilencing were detected by RT-PCR technology and western blot assay. RESULTS AND CONCLUSION:Human osteoblasts that were stably transfected by ERβ-shRNA-3 retroviral vector was selected successful y, and ERβsilencing had no significant influence on the cel proliferation (P>0.05). Under the interference of estrogen, the silencing efficiency of ERβprotein was (93.11±0.57)%(P<0.05), and after ERβsilencing, the expressions of TGF-β1 and BMP-2 were increased by (26.65±3.81)%and (16.62±1.71)%at mRNA level, and increased by (23.79±3.76)%and (18.08±3.20)%at protein level (both P<0.05). In conclusion, ERβmay play an important role in bone metabolism by regulating the expressions of TGF-β1 and BMP-2.

Objective: To determine the clinical efficacy and feasibility of multiple special formed titanium mesh cages (TMCs) to treat lumbo-sacral spinal tuberculosis via posterior approach. Methods: From July, 2007 to June, 2013, 25 patients with lumbo-sacral spinal tuberculosis underwent one-stage posterior debridement, internal if xation, and interbody fusion using multiple special formed titanium meshes. We compared the parameters as follow: the pre- and post-operative American Spinal Injury Association (ASIA) score, lumbo-sacral angle, the height of intervertebral space, visual analogue scale (VAS), and erythrocyte sedimentation rate (ESR), and observedoperation time, intraoperative blood loss, and time of bone gratf fusion. Results: Operation time ranged from 90 to 180 min, (128±24) min in average. Blood loss in the operation ranged from 100 to 800 mL, (310±125) mL in average. hTe patients were followed up for 24 to 59 months, (43±7) months in average. One patient delayed healing of wound. ASIA score was improved in a certain degree in patients with neurological dysfunctions. hTe lumbo-sacral angle and the height of intervertebral space in the post-operation were signiifcantly higher than those in the pre-operation (P<0.001). VAS was reduced obviously atfer 2 weeks of operation. hTe ESR recovered to the normal level 6 months atfer operation in all the patients. Solid fusion was achieved within 4 to 8 months, 6 months in average. No sinus tract, cerebrospinal meningitis, tuberculosis recurrence and titanium mesh subsidence were found. Conclusion: For lumbo-sacral tuberculosis, multiple special formed titanium mesh cages via posterior approach is safe and effective, which is good to the stability in spine reconstruction.

Objective To evaluate the clinical effect of one-stage posterior-anterior approach surgery for patients with cervical fracture and dislocation combined with locked facet.Methods A retrospective review was conducted on 21 cases of cervical dislocation and fracture combined with locked facet treated by one-stage posterior-anterior approach surgery between April 2011 and December 2012.There were 16 males and 5 females at age ranging from 23 to 61 years (mean,38.3 years).Posterior unlocking reduction by partial facetectomy and lateral mass screw fixation was performed,followed by anterior decompression,internal fixation and interbody fusion by titanium meshes.Outpatient or telephone follow-up was performed to evaluate bone fusion and recovery of neurologic function.Results Mean operation time was 140 minutes (130-210 minutes) and mean blood loss was 340 ml (range,150-600 ml).All incisions got primary healing with no operation-correlated complications.Five patients complicated with severe lung infection after surgery and one died of respiratory failure two week later.Titanium meshes achieved bone fusion within 3-9 months (mean,6 months) after surgery.At a mean follow-up of 17 months (range,12-30 months),there was no implant breakage and mesh displacement or collapse.According to the American Spinal Injury Association (ASIA) score,preoperative neurologic deficit restored by mean one grade at final follow-up.Conclusion One-stage posterior-anterior approach surgery is an ideal choice for cervical fracture and dislocation combined with locked facet,for it provides unlocking reduction,canal decompression,and rigid reconstruction of the anterior-posterior column.
