BACKGROUND:Currently,the main purpose of surgical treatment for lumbar compression fractures is to improve symptoms,reduce pain,improve quality of life,minimize surgical risks,and reduce surgical exposure time.OBJECTIVE:To explore the safety and clinical efficacy of percutaneous vertebroplasty via Kambin's triangle in the treatment of senile spinal deformity accompanied by osteoporotic vertebral compression fractures.METHODS:A retrospective analysis was conducted on 31 patients with spinal deformity and osteoporotic vertebral compression fractures who were admitted to Tianjin Union Medical Center from January 2019 to December 2022.There were 21 males and 10 females,aged between 60 and 84(70.0±10.3)years old.The duration of illness ranged from 1 to 6(3.5±1.7)weeks.A total of 35 vertebral segments were affected.The distribution of vertebral compression fractures included:10 cases of L1 fracture,12 cases of L2 fracture,2 cases of L1+L2 fracture,5 cases of L3 fracture,and 2 cases of L1+L3 fracture.Based on the surgical approach,patients were divided into two groups:group A(via Kambin's triangle approach)with 15 cases,and group B(via traditional pedicle puncture)with 16 cases.Unilateral approach vertebroplasty was performed on both groups.The surgical duration,number of radiation exposures,presence of bone cement leakage,occurrence of complications such as nerve and vascular injuries were recorded in both groups.Postoperative CT scans were used to observe the dispersion and hardening of bone cement.RESULTS AND CONCLUSION:(1)In the group A,the surgical duration was 21-30 minutes per vertebra,with an average of(25.0±5.7)minutes.In the group B,the surgical duration was 25-43 minutes per vertebra,with an average of(33.0±7.2)minutes.The surgical duration for puncturing a single vertebra was significantly longer in the group B compared to the group A,with a statistically significant difference(P＜0.05).(2)The average number of radiation exposures per vertebra during surgery was(6.2±1.6)in the group A and(9.3±1.8)in the group B,with a statistically significant difference between the two groups(P＜0.05).(3)In the group A,no bone cement leakage was found.In group B,2 cases had bone cement leakage,and 1 case had bone cement entering the spinal canal,but no obvious neurological symptoms were observed.The leakage rate was 13％.Both groups had 1 case of subcutaneous hematoma.(4)Postoperative CT scans for observing the distribution of bone cement in the vertebral body showed that the rates of uniform dispersion of bone cement within the vertebrae were 71％and 33％in the groups A and B,respectively,with a statistically significant difference between the two groups(P＜0.05).(5)It is suggested that percutaneous vertebroplasty via Kambin's triangle approach offers advantages such as shorter surgical duration,better dispersion and filling of bone cement within the vertebrae,lower risk of complications,reduced radiation exposure,and satisfactory results with unilateral puncture.

Objective To evaluate the clinical efficacy of selective expansive open-door laminoplasty(SEOLP)with preservation of C7 spinous process in the treatment of multisegmental cervical spondylotic myelopathy and its impact on changes in sagittal parameters of cervical spine.Methods A retrospective analysis was conducted on the clinical data and radiological information of 73 patients who underwent expansive open-door laminoplasty(EOLP)for cervical spondylotic myelopathy in our department between March 2018 and June 2022.Patients were divided into the SEOLP group(n=35)and the EOLP group(n=38)based on the surgical method.Follow-up was conducted for one year.The operation time,blood loss,axial symptom scores,JOA scores,VAS scores and neck disability index(NDI)were recorded in two groups of patients.Radiological data were also recorded for both groups during the perioperative period,and the C2-7 Cobb angle,C2-7 SVA and T1 slope were measured.The cervical curvature index(CCI)and cervical range of motion(ROM)were calculated.The perioperative clinical outcomes and changes in cervical sagittal parameters were observed,and their correlations were analyzed.Results There were no significant differences in blood loss,operation time,JOA scores at various follow-up time points between the two groups(P＞0.05).During postoperative follow-up,axial symptoms were observed in 5 patients in SEOLP group and 14 patients in EOLP group.There were statistically significant differences in axial symptom scores,incidence and severity of axial symptoms between the two groups(P＜0.05).The NDI indices at one year after operation were 21.1±2.3 for SEOLP group and 24.8±3.5 for EOLP group respectively(P＜0.01).There were no statistically significant differences in T1 slope and C2-7 Cobb angle at various follow-up time points after surgery between the two groups(P＞0.05).One year after operation,CCI indices for two groups were(13.4±2.7)and(12.1±2.4),respectively,with a statistically significant difference(t=2.178,P＜0.05).The C2-C7 SVA values for two groups at one year after operation were(22.4+3.8)mm and(26.7±5.9)mm,respectively(t=3.667,P＜0.01).The results of the correlation analysis showed that there was a significant negative correlation between clinical functional improvement(NDI)and changes of the radiological parameter C2-C7 SVA in both groups of patients.Conclusion After SEOLP,the recovery of C2-C7 SVA is faster and has less impact on cervical spine function,and the occurrence degree and incidence of axial symptoms are lower.

Rheumatoid arthritis(RA)is a chronic autoimmune disease with a high risk of disability.Macrophages,as important immune cells,participate in the regulation of inflammatory response and bone homeostasis in RA by polarization to different phenotypes.This article reviewed the etiology and pathogenesis of RA in TCM.It was found that imbalance in macrophage polarization is a key factor contributing to inflammation and imbalance in bone homeostasis in RA.During the development of RA,M1 and M2 macrophages have different characteristics of yin and yang attributes and play different roles,which are similar to the connotation of mutual opposition,mutual restriction and mutual transformation of yin and yang theory of TCM.Based on yin-yang theory of TCM,it is proposed to regulate the balance of yin and yang and restore the homeostasis of macrophage to delay the progression of RA,hoping to provide ideas for clinical treatment of RA.

Objective: In the present study, molecular subtypes were determined, programmed deathligand 1 (PD-L1) and tumor-associated immune cells (TAICs) were quantitatively detected, and their effect on prognosis in uterine carcinosarcoma (UCS) was analyzed. Methods: The study included 65 UCS cases. Direct sequencing of POLE exonuclease domain and immunohistochemistry of mismatch repair (MMR) deficiency proteins and p53 were used to stratify molecular subtypes. QuPath was used for quantitative immunohistochemical detection of PD-L1 and TAICs. The chi square test was used to determine the association between molecular subtypes and expression of PD-L1 and TAICs. The Kaplan–Meier method and Cox proportional hazards regression were used for plotting and survival analysis. Results: In 65 UCS cases, 1 case (1.5%) was POLE ultramutated (POLEmut) subtype, 11 cases (16.9%) were deficient MMR (dMMR) subtype, 32 cases (49.3%) were p53 mutant (p53mut) subtype, and 21 cases (32.3%) were nonspecific molecular profile (NSMP) subtype. The positive density of PD-L1 in tumor (p=0.022), CD8 in stroma (p=0.036), and CD163 in stroma (p=0.025) were significantly associated with molecular subtypes. The patients with POLEmut and dMMR subtypes had a relatively better prognosis trend than patients with NSMP and p53mut subtypes. The patients with high positive density of PD-L1 in tumor had significantly better prognosis; however, high positive density of CD163 in stroma showed significantly worse prognosis. Conclusion UCS could be classified into four molecular subtypes associated with prognosis.PD-L1 and M2 macrophages could effectively predict the prognosis of patients with UCS.
