ObjectiveTo evaluate the efficacy of rehabilitation associated with local intramuscular injection of botulinum toxic A (BTX-A) on spastic cerebral palsy (CP).Methods60 children with spastic CP were divided into experimental group and control group with 30 cases in each group. Cases of experimental group were treated with rehabilitation associated with local intramuscular injection of BTX-A. Cases of control group were treated only with rehabilitation treatment. The therapeutic efficacies of two groups were evaluated with physician rating scale (PRS) and activities of daily living (ADL) evaluation systems.ResultsImprovement of clinical evaluations index-PRS and ADL in experimental group was much more significant than that of control group (P<0.05). ConclusionRehabilitation associated with local intramuscular injection of BTX-A can improve the efficacy of spastic CP.

We have assessed the relationships between immune trait (antibody titers of Sheep red blood cell, SRBC; Avian influenza, AI; Newcastle disease, ND) and varieties of MHC B-LBHII Gene in local chicken breeds (Wenshang Barred chicken, LH; Laiwu Black chicken, LWH; and Jining Bairi chicken, BR). We selected 300 chickens randomly from the three indigenous chicken populations. The variations of MHC B-L BII gene were detected by directly DNA sequencing and polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP). The results indicated that there were about 19-22 nucleotide mutations in the three local breeds, which could affect 16-18 amino acid variations. Another results indicated that there was significantly relationship between seven to eight SNPs of the MHC B-LBII region and some immune traits (P < 0.05 or P < 0.01). Both locus G97A and locus T138A were found in the three species, which were significantly related to the antibodies of SRBC, ND and AI antibody titers (P < 0.05). Among them, the locus G97A was significantly associated with ND antibody titers (P < 0.05) in BR chicken, with SRBC antibody titers (P < 0.05) in LWH chicken, and with H9 antibody titers (P < 0.05) in LH chicken. Furthermore, locus T138A was significantly associated with H9 antibody titers in BR and LH chickens (P < 0.05). All those results suggest relationships among the different varieties of MHC B-LBII and immune traits in the three local breeds.

Objective:To explore the clinical outcome of early endoscopic realignment with flexible cystoscope for pelvic fracture urethral injury.Methods:We retrospectively collected and analyzed the clinical data of patients with pelvic fracture urethral injuries in ER of Beijing Jishuitan Hospital from March 2018 to June 2022.Seventy-six male patients with PFUI were reviewed and 60 patients were included due to the integrity of data collected. The patients were divided into early endoscopic realignment (EER) group and suprapubic cystostomy (SC) group according to the acute management. There were 33 patients and 27 patients in EER group and SC group, respectively. The age of the patients were (42.2±13.8)years and (44.1±15.0) years in EER group and SC group, respectively. The causes of the injuries were car accident, falling and crush, the percentage of the patients were 60.6%(20 cases), 33.3%(11 cases), 6.1%(2 cases) and 55.6%(15 cases), 44.4%(12 cases), 0 in EER group and SC group, respectively. The difference between two groups was statistically insignificant. The procedure of EER began with a cystostomy guided by B ultrasound, then an antegrade cystoscopy was performed through the cystostomy while negociating the bladder neck to the proximal side of injured urethra. A ureteral stent was inserted into the broken urethra and retrieved by a forceps through retrograde urethroscopy with another flexible cystoscope. We inserted a guidewire into the ureteral stent before removing it and placed a 16F urethral catheter along the guidewire. We analyzed the difference between two groups including the incidence, the length and the management of urethral stricture and the complexity of urethroplasty if needed. The simple urethroplasty was defined as performing anastomosis after dissection of the bulbar urethral and removing the scar tissue, while the procedure was defined as complex urethroplasty if ancillary procedures, such as separating the corporal bodies and partial pubectomy, was needed.Results:The EER group and SC group had 33 patients and 27 patients, respectively. The mean operation time of EER was (24.5±7.0)minutes and there was no intra-operative complications. Postoperatively, 4 cases of bleeding and 2 cases of UTI were found, which were successfully treated by conservative managements. Twenty-eight out of 33 patients(84.8%) in EER group developed urethral stricture and the mean length of it was (3.10±1.20)cm. However, all patients in SC group developed urethral stricture (100.0%) with the mean stricture length of (3.83±1.18)cm. The difference between two groups in term of the length of stricture was statistically significant ( P=0.026). 24 patients(85.7%) in EER group were treated by urethroplsty, 2 patients(7.1%) with endoscopic urethrotomy and 2 patients (7.1%) with dilation. All were treated with urethroplasty but 2 patients with endoscopic in SC group. In EER group, 8 strictures (33.3%)finished with simple urethroplasty and 16 strictures (66.7%) with complex urethroplasty.While in SC group, 6 strictures(24.0%) completed with simple urethroplasty and 19 strictures (76.0%)with complex urethroplasty. The complexity of urethroplasty performed in EER group was not statistically significant when compared with it in SC group( P=0.538). Conclusions:The procedure of EER with flexible cystoscope is reliable and safe. Most patients with formed urethral stricture after PFUI would be treated with urethroplasty. EER can reduce the urethral stricture formation and may decrease the need of the ancillary procedures during the urethroplasties if needed.
