The regulation of immune response is affected by several factors in order to maintain homeostasis.Indoleamine 2,3-dioxygenase(IDO) is a tryptophan-catabolizing enzyme expressed by different types of APC,including macrophages and dendritic cells.IDO activity leads to regulatory effects on T cells,which are mediated by tryptophan depletion in specific local tissue microenvironments,the production of proapoptotic metabolites,and inhibition of T-cell clone proliferation through regulatory T cells.IDO plays an important role in protecting the allogeneic fetus from rejection,the development of autoimmune diseases,allograft rejection,and cancer.So regulation of IDO activity may offer a novel drug-based strategy to treat immune-related diseases.

BACKGROUND: Percutaneous vertebroplasty for osteoporotic vertebral compression fractures has achieved very good results, but its long-term efficacy as well as impact on patients has been rarely reported so far.OBJECTIVE: To investigate the long-term effect of vertebroplasty with bone cement on osteoporotic vertebral compression fractures through a follow-up.METHODS: Thirty-four patients with osteoporotic vertebral compression fractures who had undergone percutaneous vertebroplasty were recruited. Visual analogue scale scoring was measured and compared as well as lesioned vertebral height and kyphosis angle shown on lateral X-ray examination prior to, 1 week and 6 years after percutaneous vertebroplasty.RESULTS AND CONCLUSION: The kyphosis angle was improved 1 week and 6 years after percutaneous vertebroplasty, and it changed insignificantly during the follow-up period. The vertebral height was also improved significantly after percutaneous vertebroplasty (P < 0.01); however, there was no obvious variation in the vertebral height at 1 week and 6 years after percutaneous vertebroplasty. The visual analogue scale exhibited an improvement after percutaneous vertebroplasty (P < 0.01); however, with time going by, the scoring on the visual analogue scale had an increased tend. All the parameters remained stable and had no large fluctuations. It is proved that the percutaneous vertebroplasty is effective and safe to treat osteoporotic vertebral compression fractures with an excellent long-term effect.

Three kinds of fortified biscuits and bread were given as breakfast for 5 months to 106 preschool children 4-6 years old lodged in a kindergarten, with a control group taking common biscuits and bread without fortification. 6 g protein and 160 kcal were supplied by 50 g of fortifed foods in which 0.25 g lysine, 0.25 g lysine and 0.8 mg riboflavin, and cod liver oil and calcium in addition to lysine and riboflavin were fortified respectively. The results showed that a diet with intake of 2.1 g protein and 71 kcal/kg body weight fortified on the average by 228 mg lysine or 228 mg lysine and 1.1 mg riboflavin increased the monthly increment of body weights, heights, and urinary excretions of creatinine per day. There was also a tendency of improvement, in nitrogen retention. The urinary excretion of riboflavin in load test was increased in the group taking the second kind of fortified foods.

OBJECTIVE:
To investigate the law of auditory remodeling by studying the Cortical Auditory Evoked Potential in a group of post-lingually deaf adults in the early stage of the cochlear implant use.
METHOD:
Ten post-lingually deaf adults implanted with PULSAR ci 100 of Medel device ranged from 19 to 52 years old with duration of deafness from 3 months to 23 years.were involved. Their P1-N1-P2 responses to /ba/ at around 60-70 dB SPi and open-set speech recognition scores of mono-syllabic words were recorded at 1. 3 and 6 months after the switch-on of cochlear implants.
RESULT:
Six out of 10 typical waveforms of Pl-N1-P2 were obtained. The other I were with atypical waveforms. The group with atypical waveform was characterized by long duration and early onset of deafness. There was no significant difference regarding either the amplitude or the latency of each peak at the 3 data collection time points. There was significant difference among the 3 data collection time points about the speech recognition scores with the highest score at the 6th month of switch on. There was no significant correlation between the peak of the CAEP and speech recognition score.
CONCLUSION
In the first 6 months of cochlear implant use in the post-lingually deaf adults, the duration and the onset age of deafness played important role in respect of the presence and waveform morphology of the CAEPs. It needs at least 6 months for the central auditory system to make use of the audio input from the cochlear implant.

Objective:To evaluate the accuracy and safety of cervical pedicle screw (CPS) placement under orthopaedic robot navigation system guidance.Methods:From March 2019 to February 2021, the data of 33 patients (19 males and 14 females, aged from 26 to 75 years, with an average age of 50.5 years) treated with pedicle screw fixation with the assistance of orthopaedic surgery robot through the posterior cervical spine were retrospectively analyzed. In clinical diagnosis, there was upper cervical fracture with instability in 14 patients (fracture nonunion in 2 patients), upper & subaxial cervical fracture in 1 patient, cervical spinal cord injury with spinal stenosis in 2 patients, cervical spinal stenosis in 9 patients, occipitocervical deformity in 2 patients, post-operative revision of cervical spondylosis in 2 patients, cervical intraspinal tumor in 3 patients. A total of 151 CPSs were inserted in C 1-C 7 using robot navigation system based on intraoperative three-dimensional C-arm fluoroscopy to assist in screw placement in posterior cervical surgery. Among them, 74 screws were implanted into upper cervical spine; 77 screws were implanted in the lower cervical spine. CT was used to obtain image data within 7 days after operation, and Neo classification was used to evaluate the accuracy of cervical pedicle screw placement. The patients were followed up for 2 weeks to observe the clinical symptoms and signs, and to determine whether there were surgical complications such as nerve and blood vessel injury and incision infection. Results:According to Neo classification, 91.4% (138/151) screws were completely contained in the pedicle without breaking through the pedicle cortex (grade 0). Among them, the accuracy of C 1 screws was 97.1% (34/35), C 2 screws was 92.3% (36/39), C 3 screws was 88.2% (15/17), C 4 screws was 71.4% (10/14), C 5 screws was 85.7% (12/14), C 6 screws was 93.3% (14/15), C 7 screws was 100.0% (17/17). The screw accuracy was highest in C 7, the lowest in C 4. The Kruskal-Wallis H test was performed on the accuracy of screw placement in different cervical level, and the results showed that there was no statistical difference (χ 2=1.31, P=0.971). However, a total of 13 screws were found to perforate the cortex of pedicle, although any neural or vascular complications associated with CPS placement were not encountered. Among them, 9 screws were found to perforate laterally, and 4 screws were found to perforate medially. No postoperative incision infection occurred in all cases. Conclusion:The safety of CPS placement can be effectively guaranteed with the assistance of the orthopaedic robot system.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.
