Objective: To observe the effect of moxibustion on the expressions of tumor necrosis factor-α (TNF-α) and nuclear transcription factor kappa B (NF-κB) proteins in ankle joints of rats with rheumatoid arthritis (RA), and to explore the anti-inflammatory mechanism of moxibustion in the treatment of RA.Methods: Adjuvant arthritis (AA) rat models were induced and used as rat models of RA. Rats were randomly divided into a normal group, a model group, a moxibustion group and a saline group. Rats in the normal and model groups were not treated; rats in the moxibustion group accepted treatment by moxibustion at Zusanli (ST 36) and Shenshu (BL 23) after modeling; rats in the saline group were injected with 0.15 mL saline to the bottom of the left hind paw and had no other treatments. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes of rats' ankle joints under light microscope. Immunohistochemistry was used to observe the expressions of TNF-α and NF-κB in ankle joints of rats.Results: Compared with the normal group, the rats' ankle joints in the model group showed disorganization, joint surface defect, and significantly increased mean optical density (MOD) of TNF-α and NF-κB (allP<0.05). After moxibustion treatment, rats in the moxibustion group showed repaired ankle tissues, smooth joint surface without defects, decreased MOD of TNF-α and NF-κB than those in the model group (allP<0.05). Rats in the saline group had no damage to ankle joints, while TNF-α and NF-κB were significantly different from those in the model group (P<0.05).Conclusion: Moxibustion could down-regulate the expressions of NF-κB and TNF-α protein in ankle joints of RA rats, and produce an anti-inflammatory effect to promote tissue repair.

Objective:To survey on the status quo of the management capabilities of general practice team leaders in community health service centers in Shanghai.Methods:Using stratified sampling method, 18 community health service centers in the urban and suburban areas of Shanghai were selected, then the general practice team leaders and general practitioners (team members) in the centers were selected as the study participants. The questionnaire survey on the management capabilities of general practice team leaders was conducted among selected participants from November to December 2021. The self-assessment by general team leaders and the other-assessment by team members were carried out, and the total scores was calculated according to the weight of self-evaluation score (30%) and other-evaluation score(70%).Results:A total of 110 general practice team leaders and 749 team members participated in the survey. Among the team leaders, 63.64% (70/110) were females, 82.73% (91/110) were bachelor degree holders, 71.82% (79/110) had intermediate professional title, and 50.91% (56/110) worked for more than 9 h per day. The total score of general practice team leaders was (87.15±10.76) points, the other-assessment score was significantly higher than self-assessment score ((88.62±9.34) vs.(83.71±14.08), t=2.22, P<0.05). The average score of the 5 dimensions was 4.41 for special business management, 4.39 for organizational management, 4.38 for personal quality, 4.27 for teaching and research management and 4.22 for strategy and cultural construction, respectively. Conclusion:The overall management capabilities of Shanghai community general practice team leaders are at the upper-middle level, however, the capabilities in scientific research and team planning are relatively weak.

Objective:
To study the molecular features of metanephric adenoma (MA) and discuss their values in differential diagnosis.
Methods:
BRAF V600E immunohistochemistry (IHC) using the mutation-specific VE1 monoclonal antibody and Sanger sequencing of BRAF mutations were performed on 21 MAs, 16 epithelial-predominant Wilms tumors (e-WT) and 20 the solid variant of papillary renal cell carcinomas (s-PRCC) respectively. p16 protein was detected by IHC also. Fluorescence in situ hybridization (FISH) analyses using centromeric probes for chromosome 7 and 17 were performed on the three renal tumors in parallel.
Results:
Fourteen (14/21, 66.7%) of 21 MA cases demonstrated diffuse, moderate to strong cytoplasmic BRAF V600E IHC staining and the BRAF V600E protein expression was detected in 2 (2/16) of 16 e-WT cases for the first time, whereas all s-PRCCs were negative (
