Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Objective:To investigate the clinical effect of lingual mucosal augmentation urethroplasty with non-transecting urethral cavernous anastomosis in the treatment of traumatic urethral stricture.Methods:The clinical data of 39 patients with traumatic urethral stricture admitted to our clinical center from March 2023 to December 2023 were retrospectively analyzed. Their mean age was (49.7±2.0)years. The cause of urethral injury was pelvic fracture in 32 cases, riding injury in 5 cases, and iatrogenic injury in 2 cases. Suprapubic vesicostomy tube was indwelled before operation in 39 cases. There was 1 case with hypospadias and 1 case with urethral false passage. 9 patients had urethral dilatation before surgery, 5 had internal urethrotomy operation, 5 had urethroplasty, and 22 had no history of urethral surgery. The International Erectile Function Index (IIEF-5)score of 39 cases last 1 month before surgery was collected and classified.In which, the IIEF-5 score of 19 cases with no or mild erectile dysfunction was median 20 (18, 23)points, the MSHQ-Ejd score was median 16 (11, 19)points, and the number of effective erections was median 4(3, 5)times on the NPT. And in which, the IIEF-5 score of 20 cases with moderate to severe erectile dysfunction was median 10 (3, 14)points, the MSHQ-Ejd score was median 3(1, 7)points, and the number of effective erections was median 1(0, 2)times on the NPT. All 39 cases underwent non-transecting anastomotic lingual mucosal augmentation urethroplasty. The central tendon of the perineum and the ventral side of the bulbar urethra were preserved through perineal approach. The dorsal side of the urethra was mobilized and through the dorsal side of the urethra, the scar of the urethra was enucleated along the mucosa of the urethra. Then the ventral mucosa of the urethra was anastomosed end to end and the dorsal urethra was repaired by lingual mucosa transplantation. The Clavien-Dindo complication grading system was performed. The catheter was removed 4 weeks after operation, and urine flow rate was recorded 1 month after extubation. IIEF-5 score, MSHQ-Ejd score and NPT were recorded 6 months after operation.Results:The mean operation time of 39 cases was (118.0±18.3)min. 39 cases were followed up for median 8.0(6.0, 10.0)months. The Q max ≥15 ml/s in 24 cases. The Q max <15ml/s in 13 cases, of which, the Q max ≥15 ml/s after 1 internal urethrotomy operation in 10 cases and Q max≥15 ml/s after 2 internal urethrotomy operations in 3 cases. 2 cases were still failed to urinate and Q max≥15 ml/s after end-to-end urethral anastomosis. All 39 cases’ Clavien-Dindo complications were graded Ⅰ.Of the 19 cases with no or mild erectile dysfunction, the IIEF-5 score was median 20(17, 23)points, the MSHQ-Ejd score was median 16(11, 19)points, and the number of effective erections was median 4(3, 4)times on the NPT postoperatively, all were not significantly different from those before operation ( P> 0.05). Of the 20 cases with moderate and severe erectile dysfunction, the IIEF-5 score was median 9(4, 13)points, the MSHQ-Ejd score was median 4(2, 7)points, and the number of effective erections was median 1(0, 2)times on the NPT postoperatively, and all were not significantly different from those before operation ( P>0.05). Conclusions:Non-transecting anastomotic lingual mucosal augmentation urethroplasty is a reliable surgical method with few complications for traumatic urethral stricture. Moreover, the operation has little effect on the sexual function of patients.

Objective:To explore the value of contrast enhanced ultrasonography(CEUS) combined with shear wave elastography (SWE) in the diagnosis of urethral stricture.Methods:One hundred and twenty patients with urethral stricture were recruited, and preoperative retrograde urography, common urethral ultrasound, and CEUS were used to measure the length of the stricture site, and SWE was used to detect the elasticity value of the stricture site and its nearby spongiosum. Intraoperative urethral stricture lesion site measurements were performed to confirm the actual lesion location and length during surgery and to compare them with the lengths measured in the preoperative examination;4 months after surgery, SWE was used to detect the stiffness of the surgical site and to assess the surgical efficacy and prognosis.Results:The stenosis length measured by CEUS and intraoperative measurement had no statistical difference: (4.41 ± 1.47) cm vs. (4.37 ± 1.36) cm, t = 0.22, P>0.05. The elastic value in urethra stenosis in SWE was higher than that in normal urethra: (33.1 ± 6.7) kPa vs. (23.3 ± 4.1) kPa, there was statistical difference ( t = 13.67, P<0.05). The elastic value of unobstructed urethra and that of normal urethra after reconstruction had no statistical difference ( t = 0.95, P>0.05). Conclusions:CEUS combined with SWE is a safe, accurate and effective method to evaluate urethral stricture. SWE can be used to measure postoperative outcomes and recurrence.

Objective:To investigate the effect of integrated psychological and behavioral intervention on cognitive function and P300 in children with attention-deficit/hyperactivity disorder (ADHD).Methods:A randomized controlled study was conducted on 112 children with ADHD admitted to the Shaoxing 7 th People's Hospital from March 2022 to September 2023. These children were randomly divided into two groups: Group A ( n = 56) and Group B ( n = 56), using a random number table method. Group A received conventional drug treatment, whereas Group B received conventional drug treatment and an integrated psychological and behavioral intervention. The treatment lasted for 3 months. Before and after treatment, the levels of norepinephrine (NE) and dopamine (DA), scores on the Integrated Visual and Auditory Continuous Performance Test, electroencephalogram θ/β ratio, and P300 (latency and amplitude) were determined in each group. The clinical efficacy of the treatment was evaluated in both groups. Results:After treatment, the NE and DA levels in Group B were (340.83 ± 43.22) ng/L and (1.12 ± 0.25) ng/L, respectively. These levels were significantly lower than those in Group A [(416.15 ± 48.37) ng/L, (1.30 ± 0.31) ng/L, t = 8.69, 3.38, both P < 0.05]. The full scale attention quotient and full scale response control quotient in Group B were (82.52 ± 14.15) points and (96.34 ± 13.95) points, respectively. These values were significantly higher than those in Group A [(75.20 ± 13.83) points, (90.62 ± 15.16) points, t = -2.77, -2.08, both P < 0.05). The electroencephalogram θ/β ratio was significantly lower in Group B than in Group A ( t = 3.22, P < 0.05). The latencies of P300 in the Cz and Fz regions in Group B were (346.21 ± 40.52) ms and (344.65 ± 39.52) ms, respectively. The latencies were significantly shorter than those in Group A [(376.16 ± 43.04) ms, (369.35 ± 42.16) ms, t = 3.79, 3.20, both P < 0.05]. Similarly, the amplitudes of P300 in the Cz and Fz regions were significantly greater in Group B [(7.73 ± 1.80) μV, (7.22 ± 1.73) μV] than in Group A [(5.90 ± 1.15) μV and (5.76 ± 1.12) μV] ( t = -6.41, -5.30, both P < 0.05). The total response rate in Group B was significantly higher than that in Group A [94.6% (53/56) vs. 82.1% (46/56), χ2 = 4.26, P < 0.05]. Conclusion:The integrated psychological and behavioral intervention in children with ADHD is good. It can reduce NE and DA levels, improve cognitive function, decrease electroencephalogram θ/β , and improve P300.

【Objective】 To evaluate the safety and efficacy of transobturator bulbourethral suspension with modified four-armed pelvic sling for post-prostatectomy incontinence (PPI). 【Methods】 The clinical data of 78 male PPI patients treated during Jan.2012 and Dec.2017 in our hospital were collected. The incontinence quality of life (I-QOL) score, daily use of urine pad, 1-hour urine pad test, residual urine volume (RUV), and maximum flow rate (Qmax) were assessed before and after surgery. 【Results】 The total success rate was 79.5%, of which the cure rate was 56.4% and the improvement rate was 23.1%. The preoperative I-QOL score was (54.6±3.9), daily use of urinary pad was (3.6±0.7), and increase in weight of the 1-hour urine pad test was (33.6±5.0) g. Three years after surgery, the I-QOL score was (80.4±5.7), daily use of a urinary pad was (1.9±0.4), and increase in weight of the 1-hour urine pad test was (7.4±1.3) g. Compared to preoperative status, the I-QOL score, daily use of urine pad, and increase in weight of the 1-hour urine pad test 3 years after surgery improved significantly (P<0.05). During the mean follow-up of (61.4±20.5) months, no significant changes in the I-QOL score, daily use of a urinary pad, 1-hour urinary pad test, RUV or Qmax were observed, and no complications occurred. 【Conclusion】 Transobturator bulbourethral suspension with modified four-armed pelvic sling is an effective and safe procedure to treat post-prostatectomy incontinence. The long-term efficacy is satisfactory.

Objective:To explore whether thyroxine (T 4) could promote differentiated thyroid cancer (DTC) progression by binding to integrin α vβ 3in vitro and its downstream mechanism. Methods:Papillary thyroid cancer cell lines TPC-1, K1 and follicular thyroid cancer (FTC) cell line FTC133 were cultured in vitro, and the expressions of integrin α vβ 3 in those 3 DTC cell lines were determined with immunofluorescence and flow cytometry analysis. After the treatment of T 4, tetraiodo thyroacetic acid (Tetrac) and Arg-Gly-Asp (RGD) peptide alone or in combination, the proliferation and metastatic potential of DTC cell lines were detected by cell counting kit-8 (CCK-8), Transwell migration and invasion assays. The small interfering RNA (siRNA) transfection was used to verify whether integrin α v or β 3 subunit knockdown could reverse the effect of T 4 on DTC cells. The expression levels of downstream signaling proteins phosphorylated extracellular signal-regulated kinase (p-ERK)1/2 and total extracellular signal-regulated kinase (ERK)1/2 were detected by Western blot. The effects of mitogen-activated protein kinase kinase (MEK)1/2 inhibitor (GSK1120212) on the proliferation, migration and invasion of T 4-treated cells were detected. One-way analysis of variance and Tukey test were used for data analysis. Results:The integrin α vβ 3 expressions in TPC-1, K1 and FTC133 cells were all positive, with the relative mean fluorescence intensity (MFI) of 61.93±18.61, 16.89±2.43 and 32.36±0.83, and the percentages of positive cells of (94.38±1.30)%, (74.11±3.87)% and (50.67±1.78)%, respectively ( F values: 13.36 and 217.30, P=0.006 and P<0.001). Compared with control group, the proliferation, migration and invasion in the three DTC cell lines treated with T 4 were significantly enhanced (96 h, F values: 62.67-297.50, q values: 13.15-20.73, all P<0.001). T 4-induced cell proliferation, migration and invasion were markedly reversed by Tetrac or RGD (96 h, q values: 8.61-17.54, all P<0.001). T 4-induced cell proliferation, migration and invasion were also significantly inhibited by the knockdown of integrin α v or β 3 subunit (72 h, F values: 7.75-70.98, q values: 4.77-15.21, all P<0.05). Western blot results showed that the phosphorylation levels of ERK1/2 in DTC cells were significantly increased by T 4 treatment, and the T 4-induced activation of ERK1/2 signaling pathway could be blocked by Tetrac, RGD, integrin α v or β 3 subunit knockdown. T 4-induced cell proliferation, migration and invasion were significantly reversed by GSK1120212 (96 h, F values: 47.53-151.40, q values: 10.32-16.65, all P<0.001). Conclusion:T 4 can promote cell proliferation and metastasis of DTC cells by binding to integrin α vβ 3 and activating the ERK1/2 pathway.

Objective:To summarize the ideal strategy for the treatment of female hypospadias.Methods:The data of 12 female patients with hypospadias admitted to the Sixth People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine from December 2011 to December 2019 were retrospectively analyzed. The patients was (31.0±16.6) years old (7-67 years old). Among them, 3 cases had a history of pelvic fracture trauma, 3 cases had a history of birth trauma, and the remaining 6 cases had no history of trauma and surgery. Among them, there were 6 cases of congenital hypospadias and 6 cases of acquired hypospadias. The clinical manifestations were urinary incontinence in 6 cases and dysuria in 6 cases. Examination of the normal position of the external opening of the genital urethra did not show the opening of the urethra, but moved down to different parts of the anterior wall of the vagina. All patients underwent urethral lengthening. For congenital hypospadias, the urethral plate is used to cut the coiled tube during the operation to prolong the urethra. For acquired hypospadias, the stenotic urethra was enlarged and lengthened with a labial pedicled flap coil. The subcutaneous fat pad of the labia majora was mobilized and transferred to the outside of the newly constructed urethra to prevent the occurrence of urethro-vaginal fistula and increase the pressure of the urethra. Five patients with significant urinary incontinence underwent bladder neck reconstruction at the same time. Anatomical success of the procedure was defined as the appearance of a normal-shaped external urethral opening beneath the clitoris. Functional success was defined as the absence of moderate to severe urinary incontinence after surgery, and the maximum urinary flow rate was >15ml/s during the 12-month follow-up period.Results:All operations were successfully completed. All patients had no perioperative complications, and were followed up for 18-96 months, with an average of 57.3±32.5 months. All patients were able to urinate spontaneously after operation, 4 cases of urinary incontinence disappeared, and 2 cases improved significantly; 4 cases of patients with strenuous urination urinated smoothly. The remaining 2 cases still complained of dysuria after operation, which was solved by subsequent urethral dilatation. The anatomical repair success rate was 100.0%(12/12) and the functional success rate was 83.3% (10/12).Conclusions:Urethral lengthening is an effective method for female hypospadias. The pedicled fat pad helps to increase urethral pressure and prevent fistulas. For female patients with hypospadias and severe urinary incontinence, bladder neck reconstruction is an ideal method. of the technique.
