RÉSUMÉ

OBJECTIVE@#To investigate the synergistic interaction between the deltoid muscle and the rotator cuff muscle group in patients with rotator cuff tears (RCT), as well as the impact of the critical shoulder angle (CSA) on deltoid muscle strength.@*METHODS@#A retrospective analysis was conducted on clinical data from 42 RCT patients who met the selection criteria and were treated between March 2022 and March 2023. There were 13 males and 29 females, with an age range of 42-77 years (mean, 60.5 years). Preoperative visual analogue scale (VAS) score was 6.0±1.6. CSA measurements were obtained from standard anteroposterior X-ray films before operation, and patients were divided into two groups based on CSA measurements: CSA>35° group (group A) and CSA≤35° group (group B). Handheld dynamometry was used to measure the muscle strength of various muscle group in the shoulder (including the supraspinatus, infraspinatus, subscapularis, and anterior, middle, and posterior bundles of the deltoid). The muscle strength of the unaffected side was compared to the affected side, and muscle imbalance indices were calculated. Muscle imbalance indices between male and female patients, dominant and non-dominant sides, and groups A and B were compared. Pearson correlation analysis was used to examine the relationship between muscle imbalance indices and CSA as well as VAS scores.@*RESULTS@#Muscle strength in all muscle groups on the affected side was significantly lower than on the unaffected side ( P<0.05). The muscle imbalance indices for the supraspinatus, subscapularis, infraspinatus, and anterior, middle, and posterior bundles of the deltoid were 14.8%±24.4%, 5.9%±9.7%, 7.2% (0, 9.1%), 17.2% (5.9%, 26.9%), 8.3%±21.3%, and 10.2% (2.8%, 15.4%), respectively. The muscle imbalance indices of the anterior bundle of the deltoid, supraspinatus, and infraspinatus were significantly lower in male patients compared to female patients ( P<0.05); however, there was no significant difference in muscle imbalance indices among other muscle groups between male and female patients or between the dominant and non-dominant sides ( P>0.05). There was a positive correlation between the muscle imbalance indices of infraspinatus and VAS score ( P<0.05), and a positive correlation between CSA and the muscle imbalance indices of middle bundle of deltoid ( P<0.05). There was no correlation between the muscle imbalance indices of other muscle groups and VAS score or CSA ( P>0.05). Preoperative CSA ranged from 17.6° to 39.4°, with a mean of 31.1°. There were 9 cases in group A and 33 cases in group B. The muscle imbalance indices of the anterior bundle of the deltoid was significantly lower in group A compared to group B ( P<0.05), while there was no significant difference in muscle imbalance indices among other muscle groups between group A and group B ( P>0.05).@*CONCLUSION@#Patients with RCT have a phenomenon of deltoid muscle strength reduction, which is more pronounced in the population with a larger CSA.

RÉSUMÉ

OBJECTIVE@#To explore the safety, effectiveness and consistency of "Zoning Method" foraminotomy in posterior cervical endoscopic surgery.@*METHODS@#From March 2016 to October 2018, 21 patients with cervical spondylotic radiculopathy were enrolled. Endoscopic foraminotomy and nucleus pulposus enucleation were performed in the patients. There were 13 males and 8 females, aged from 35 to 56 years old with an average of (47.3±5.1) years. The surgical segment of 6 cases were C, 10 cases were C and 5 cases were C. The "Zoning Method" was proposed and used to complete the foraminotomy under endoscope, and then to perform nucleus pulposus removal and nerve root decompression. The operation length, intraoperative bleeding volume and complications were recorded, and NDI, VAS were evaluated before operation, 1 day after the operation and 1 week after the operation.@*RESULTS@#All the operations were successful. The operation length was(46.10±26.39) min, intraoperative bleeding volume was (50.10±18.25) ml, and there were no complications such as nerve injury, dural tear or vertebral artery injury. All 21 patients were followed up for 3 to 9 months, with a median of 6 months. Postoperative VAS and NDI were obvious improved (0.05).@*CONCLUSION@#Endoscopic foraminotomy with "Zoning Method" is safe clinically significant, and consistent.

RÉSUMÉ

OBJECTIVE@#To explore the significance of lymphocyte to monocyte ratio (LMR) in the disease progress of primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL).@*METHODS@#The clinical data of 43 patients diagnosed as PGI-DLBCL in our hospital from January 2011 to December 2015 were collected, and the disease progress was followed up.@*RESULTS@#According to the ROC curve, the threshold value of LMR for 2 years PFS (%) of PGI-DLBCL patients was 2.6. Unvariate analysis showed that LMR (P<0.05), large enclosed mass lesion (P<0.01) and IPI (P<0.05) were prognostic factors affecting PFS, the COX regression model multivariate analysis showed that LMR<2.6 [ (risk ratio (RR)=3.083, 95%CI 1.828-8.313, P<0.01], and large enclosed mass lesions (RR=2.718, 95%CI 1.339-6.424, P<0.05) were the independent adverse prognostic factor for two years PFS.@*CONCLUSION@#Both LMR<2.6 and large enclosed mass lesions relate with the progress of PGI-DLBCL.

RÉSUMÉ

Objective:To investigate the effect of epigallocatechin-3-gallate ( EGCG) on the expression of pro-inflammatory cytokines in murine bone marrow-derived macrophages ( BMDM) induced by IFN-γ/LPS.Methods:The bone marrow cells were isolated from 6-8 weeks C57BL/6 mice,which cultured in RPMI1640 medium with 10%FBS and stimulated with 100 ng/ml M-CSF in vitro,and then exposed to 50 ng/ml IFN-γand 1 μg/ml LPS with various concentrations of EGCG (12.5-50 μmol/L) .The expression of pro-inflammatory factors,IL-1β,TNF-αand iNOS were detected,in murine myeloid macrophages stimulated by IFN-γ/LPS with qRT-PCR and ELISA.Results:IFN-γ/LPS remarkably up-regulated the expression levels of inflammatory cytokines ,IL-1β,TNF-αand iNOS,but EGCG effectively repressed these cytokines expression in IFN-γ/LPS-stimulated murine myeloid macrophages , in dose-dependent manner.Conclusion:EGCG attenuates the pro-inflammatory phenotype of murine myeloid macrophages stimulated with IFN-γ/LPS.
