Allergen specific immunotherapy（AIT）, as an effective treatment for allergic rhinitis, asthma, and other allergic diseases, has received widespread attention in the field of health economic evaluation in recent years. This article reviews the current status and progress of economic research on AIT, mainly discussing the socioeconomic burden of allergic rhinitis, the results of health economic studies from different countries, and the primary methods used in health economic research on allergic rhinitis. Existing studies indicate that, although AIT involves high initial costs, it offers significant long-term economic benefits by reducing healthcare resource utilization, improving patient quality of life, and decreasing medication dependence. Moreover, reducing initial costs, applying standardized assessment tools, and conducting cross-national comparative analyses have become key directions for future research. Overall, AIT demonstrates strong potential in terms of long-term health benefits and cost savings, providing solid economic evidence for the management of allergic diseases.

Objective:To investigate the clinical and imaging characteristics of cervical spine hyperextension injury plus multilevel disco-ligamentous complex (MDLC) injury and the therapeutic effectiveness of their treatment.Methods:A total of 456 patients with cervical hyperextension injury were hospitalized between January 2010 and October 2020 at Department of Orthopaedics, The 909th Hospital, Dongnan Hospital Affiliated to Xiamen University. A retrospective study was conducted to analyze the clinical data of the 43 patients among them who had been diagnosed with MDLC injury and undergone surgical treatment and been fully followed up. They were 37 males and 6 females with an age of (50.6±10.7) years. According to the American Spinal Injury Association (ASIA) grading, there were 1 case of grade A, 8 cases of grade B, 18 cases of grade C, and 16 cases of grade D. The Japanese Orthopaedic Association (JOA) score was (7.9±1.6) points. Anterior cervical decompression, fusion and internal fixation were conducted for 42 patients, and posterior total laminectomy and internal fixation for 1 patient. The clinical and imaging manifestations of the patients, and the consistency between preoperative and intraoperative diagnosis of disco-ligamentous complex (DLC) injury were analyzed. ASIA grading and JOA score were used to assess the outcomes of surgical treatment and comparisons were made between preoperation and postoperation.Results:DLC injury existed at 99 levels (43 cases), with a high incidence at level C 5-6 (30 cases), and high-signal manifestations of cervical cord injury existed at 48 levels, with a high incidence at level C 3-4 (16 cases). Two-segment DLC injury was the most common [74.4% (32/43)], while three-segment DLC injury existed in 9 cases and four-segment DLC injury in 2 cases. There were 21 cases of jumping MDLC injury and 22 cases of continuous MDLC injury. At preoperation, DLC injury was suspected in 10 patients (at 11 levels), of whom 8 (at 9 levels) were diagnosed intraoperatively with DLC injury, and 2 (at 2 levels) were excluded from the DLC injury. All the 43 patients were followed up for (54.7±10.7) months. By the ASIA grading at the last follow-up, 3 cases were grade C, 13 cases grade D, and 27 cases grade E. The JOA score at the last follow-up was (15.1±2.2) points. Both the 2 outcomes showed significant improvements compared with the preoperative values ( P<0.05). Conclusions:The clinical incidence of cervical hyperextension injury combined with MDLC injury is low, but relatively higher in the middle-aged and elderly patients. As the level of DLC injury is often inconsistent with the likely level of cervical spinal cord injury, surgical exploration of the DLC structure with suspected injury can reduce the rate of missed diagnosis and misdiagnosis.

Objective:To study the effects of cathepsin K(CTSK)on the healing process of tooth extraction socket and type H blood vessel angiogenesis in mice.Methods:Ctsk knockout(Ctsk-/-)mice were generated by CRISPR/Cas9 technology,and genotype sequen-cing,general observation,Micro-CT and immunohistochemistry were performed to confirm successful knockout of Ctsk.Then 8 week-old WT and Ctsk-/-mice were used to establish the tooth extraction modle by extracting the left maxillary first molars,and the mice were sac-rificed at the day 7,10,14,21,28 and 35 respectively(n=3)after tooth extraction.Then samples were subjected to stereo microscope and Micro-CT examination.Immunofluorescence staining was used to study the effect of Ctsk knockout on type H blood vessel angiogene-sis.Results:Ctsk knockout did not affect the soft tissue healing of tooth extraction socket,but significantly promoted the bone healing process,and Ctsk deficency significantly enhanced type H blood vessel angiogenesis in the tooth extraction socket.Conclusion:Ctsk knockout can enhance type H vessel angiogenesis,and promote bone healing process of tooth extraction socket in mice.

ObjectiveTo investigate the mechanism of Xumingtang in Gu Jin Lu Yan （《古今录验》） in regulating cell pyroptosis through the hypoxia-inducible factor-1α （HIF-1α）/NOD-like receptor pyrin domain-containing protein 3 （NLRP3） pathway in ischemic stroke （IS）. MethodSD rats were randomly divided into a sham operation group， a model group， low- and high-dose Xumingtang groups， and a metformin group， with 20 rats in each group. Oral administration was performed for 3 days， and tissue samples were collected. Differential messenger RNA （mRNA） was screened using high-throughput sequencing， and Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway analyses were performed on key differentially expressed genes. The modified neurological severity score （mNSS） and 2，3，5-triphenyltetrazolium chloride （TTC） staining were used to evaluate the effect of brain infarction. Hematoxylin-eosin （HE） staining was used for pathological morphological observation of brain tissue. Enzyme-linked immunosorbent assay （ELISA） was used to compare the levels of interleukin-1β （IL-1β） and interleukin-18 （IL-18） in the ischemic cortical region. Double staining immunohistochemistry was used to detect the co-localization of HIF-1α and NLRP3. Real-time quantitative polymerase chain reaction （PCR） was performed to detect the mRNA expression of NLRP3， HIF-1α， Caspase-1 （CASP-1）， and gasdermin D （GSDMD）. Western blot was used to detect the protein expression of HIF-1α， NLRP3， CASP-1， and GSDMD. ResultA total of 5 705 differentially expressed genes （2 733 downregulated and 2 972 upregulated） were obtained by mRNA sequencing. After conversion to homologous genes and intersection with the pyroptosis gene set， 95 key differentially expressed pyroptosis genes were obtained. Compared with the sham operation group， the model group showed significantly increased mNSS scores， larger brain infarction areas （P<0.01）， diverse neuronal morphology， disordered arrangement， widened cell gaps， significantly increased levels of IL-1β and IL-18 in the ischemic cortical region （P<0.01）， enhanced co-localization fluorescence intensity， and significantly increased mRNA and protein expression levels of HIF-1α， NLRP3， CASP-1， and GSDMD （P<0.01）. Compared with the model group， the high-dose Xumingtang group showed the most significant improvement in neurological function scores and brain infarction areas （P<0.01）. The neuronal integrity and arrangement were more complete， and the cell gaps were narrower in all groups with drug treatment， with significantly reduced co-localization fluorescence intensity. Xumingtang could reduce the levels of IL-1β， IL-18， and the mRNA and protein expression of HIF-1α， NLRP3， CASP-1， and GSDMD （P<0.05， P<0.01）， with the high-dose Xumingtang group showing the most significant effect （P<0.01）. ConclusionXumingtang in Gu Jin Lu Yan can inhibit cell pyroptosis and promote neurological function recovery after IS， which may be related to the inhibition of the HIF-1α/NLRP3 pathway.

Objective: To summarize our preliminary clinical experience of ultrasound-guided needle-perc combined with standard percutaneous nephrolithotomy (PCNL) in the treatment of staghorn stones, and to analyze its safety and efficacy. Methods: The clinical data of 65 patients with staghorn stones treated by ultrasound-guided needle-perc combined with standard PCNL under general anesthesia with the patient in prone position from December 2017 to June 2019 were retrospectively reviewed. A total of 41 males and 24 females were included. The mean age was (53.5+ 8.9) years. The mean body mass index (BMI) was (25.1±2.9) kg/m², and the mean stone diameter was (10.9±3.1) cm. Among them, there were 3 cases with bilateral staghorn stones, 38 cases with complete staghorn calculi, 36 cases with non- or mild preoperative hydronephrosis, 12 cases with previous ipsilateral renal surgery, and 9 cases with solitary kidneys. Ultrasound-guided renal access and tract dilation were used to establish F24 standard channel. Pneumatic combined with ultrasonic lithotripsy with suction system was used to treat staghorn stones under nephroscope. Needle-perc consists of F4.2 needle-like metal sheath connected with a three-way tube. A 0.6 mm diameter video fiber, 200 um holmium laser fiber and liquid perfusion device can be connected through the three-way tube respectively. The residual stone in the parallel calyx after standard PCNL were punctured by needle-perc under ultrasound guidance, and then the holmium laser fiber was used for lithotripsy. Results: In this study, a total of 68 renal units were included. The median operative time was 79.8 minutes, ranging 45-129 minutes. The median decrease of hemoglobin on postoperative day 1 was 10.6 g/L, ranging 0-25.9 g/L. The median length of postoperative hospital stay was 5.5 days, ranging 4-7 days and the median time of tract establishment was 4.8 minutes, ranging 2.5-9.6 minutes. The median number of standard tract established was 1.5, ranging 1-3 and the median number of needle-perc punctured was 1.0, ranging 1-3. The total complication rate was 10.3% (7 cases), including 5 cases of Clavien grade Ⅰ, 2 cases of postoperative fever, 3 cases of analgesic use. There were 2 cases of Clavien grade Ⅱ. All of them were blood transfusion. The initial stone free rate was 79.4%(54/68). Of the 14 patients with residual stones, 9 patients underwent second-stage operation, 7 patients were stone free, and the final stone free rate was 89.7%(61/68). Conclusions Ultrasound-guided needle-perc combined with standard PCNL is safe and effective in the treatment of staghorn stone.
