Objective:To compare the clinical efficacy of Chevron-Akin osteotomy with cannulated compression screw and absorbable screw fixation in the treatment of moderate and severe hallux valgus.Methods:The data of 52 patients with moderate to severe hallux valgus treated in Sichuan Provincial Orthopaedic Hospital from January 2020 to December 2022 were retrospectively analyzed. According to the fixation method, they were divided into metal screw group and absorbable screw group. In the metal screw group, there were 25 cases (26 feet), 2 males (2 feet) and 23 females (24 feet), aged 36.7±4.9 years (range, 21-59 years), 12 feet on the left side, 14 feet on the right side, moderate 20 feet and severe 6 feet. There were 27 cases (29 feet) in the absorbable screw group, including 1 male (1 foot) and 26 female (28 feet), aged 34.1±5.5 years (range, 19-56 years), 16 feet on the left side, 13 feet on the right side, moderate 22 feet and severe 7 feet. The healing time and complications of osteotomy were recorded between the two groups, and the hallux valgus angle (HVA), first-second intermetatarsal angle (1-2 IMA), American Orthopaedic Foot and Ankle Society (AOFAS), hallux-metatarsophalangeal-interphalangeal joint score and visual analogue scale (VAS) for pain were compared before and after the operation.Results:All 52 patients were followed up. The follow-up time was 14.0±3.4 months (range, 11-27 months) in the metal screw group and 15.1±2.7 months (range, 13-24 months) in the absorbable screw group. In all patients, the incision healed in one stage, and no endovegetal rejection occurred. The osteotomy healing time was 3.8±0.8 months (range, 2-5 months) in the metal screw group and 3.4±1.1 months (range, 2.5-5 months) in the absorbable screw group, with no statistically significant difference ( t=1.014, P=0.417). In the metal screw group, there were symptoms of medial internal fixation irritation in 2 feet, medial osteophyte or thread knot irritation in 2 feet, and hallux valgus recurrence in 1 foot. The complication rate was 19%(5/26). In the absorbable screw group, medial osteophyte or thread knot stimulated one foot and hallux valgus recurred one foot, and the complication rate was 7%(2/29). The difference in complications between the two groups was statistically significant (χ 2=8.051, P=0.012). At 12 months after operation, for the metal screw group and the absorbable screw group, HVA (13.7°±2.1° and 12.9°±3.8°), 1-2 IMA (7.2°±1.5° and 7.8°±1.2°), AOFAS score (91.4±2.2 and 90.8±3.6 points) and VAS score (1.1±0.3 and 1.3±0.4 points), respectively, were significantly higher than those in the preoperative (HVA: 37.2°± 5.4° and 35.8°±4.7°, 1-2 IMA: 18.3°± 1.8° and 17.9°±1.7°, AOFAS score: 60.4±5.6 and 58.4±7.1 points, VAS: 6.4±0.6 and 6.8±0.4 points) improvement ( P<0.05), while there was no statistically significant difference between the two groups ( P>0.05). The incidence of complications in metal screw group was 19%(5/26), while in absorbable screw group it was 7%(2/29), with a statistically significant difference (χ 2=8.051, P=0.012). Conclusions:Both cannulated compression screw in Chevron-Akin osteotomy and absorbable screw fixation can have a good fixation effect in the treatment of moderate and severe hallux valgus. Absorbable screw fixation has the advantages of low complication rate, less interference with artifacts in later imaging examination and evaluation.

Synovium is the target organ of rheumatoid arthritis.The excessive proliferation of synovial cells and insufficient apoptosis lead to synovial hyperplasia,which in turn causes damage to the surrounding tissues of the joint and bone destruction."Yang transforming qi and yin forming elements"is derived from Su Wen and is a highly summarized description of the functions of yin and yang,which runs through the entire course of the disease.This article elucidated the theoretical connotation of"yang transforming qi and yin forming elements"and its connection with synovial hyperplasia,proposing that the insufficiency of"yang transforming qi"is the root of synovial hyperplasia,while the excess of"yin forming elements"is the manifestation of synovial hyperplasia.Based on this,it put forward that"assisting yang qi as the priority,and according to the bias of pathogenic factors of yin,supplementing the method of reducing yin forming elements"is an important principle for treating this disease,which could provide new ideas for the treatment of the disease.

Systematically sort out the successful development experience and current shortcomings of various aspects of combined Chinese and Western medicine first aid,and on this basis,we discuss the development ideas of combined Chinese and Western medicine first aid.Based on the complementary advantages of the combination of Chinese and Western medicines in first aid,it takes the special diseases with bottlenecks in the efficacy of the current single system as an entry point,and further optimizes the combination of Chinese and Western medicines in first aid through the dynamic and sequential coordination of Chinese medicine's holistic conditioning and Western medicine's targeted treatment,and promotes the development of the synergistic strategy of the first aid of Chinese and Western medicines,so as to better play the advantageous roles of the combination of Chinese and Western medicines in first aid to enhance the clinical efficacy,reduce the toxicity and side-effects,and improve the prognosis of the diseases.We also strive to promote the improvement of the dosage form of traditional first aid prescriptions and the technical innovation of the production process,so as to realize the improvement of the key indexes such as the timeliness of the onset of action,the controllability of the quality,and the targeting of the efficacy of the Chinese medicinal preparations in the first aid,in order to better support and guarantee the medicines for the first aid of the combination of traditional Chinese and Western medicines.At the same time,we should also promote the systematic construction of the standardized operation specification and efficacy evaluation system of acupuncture and moxibustion,explore the integration of acupuncture and moxibustion with modern first aid,and optimize acupuncture and moxibustion intervention strategies in emergency departments to enhance the efficacy of first aid under the restriction of medical equipments.The proposal of these suggestions may provide some enlightenment in the development of the idea of integrating Chinese and Western medicine in emergency care,and may have some reference value for the development of emergency medicine model with Chinese characteristics.

Objective Through a multi-software visual analysis of the literature on the influence of T cells on rheumatoid arthritis(RA)in recent ten years,the research hotspot and frontier development in this field were summarized.Methods The Chinese and English literature on the influence of T cells on RA from 2012 to 2022 years was retrieved from CNKI and Web of Science database as the research object.CiteSpace and VOSviewer software were used to analyze the number of publications,authors and keywords.Results 519 articles in Chinese and 861 in English were retrieved.The results showed that the number of articles in Chinese increased slowly from 2020 to 2022 years,while the overall trend in English was stable.Keyword analysis shows that it is predicted that future research in this field will focus on the pathogenesis of T cells in RA,the mechanism of bone destruction in RA,disease activity,oxidative stress.Conclusion The influence of T cells on RA has attracted much attention in the past,present and future,and has great research value.However,due to the differences in research priorities at home and abroad,the teams should interact positively and communicate with each other to reveal the internal mechanism of RA and provide theoretical basis for targeted therapy.

Rheumatoid arthritis is a common clinical autoimmune disease characterized by persistent synovitis and pannus formation. In late stage， irreversible destruction and deformation of bone and joint may occur. In this paper， the authors believe that kidney deficiency and essence deficiency is the core mechanism of rheumatoid arthritis bone destruction， and its disease evolution law is summarized as "marrow reduction， flesh flaccid， collaterals blocked". On the basis of modern medical understanding of bone destruction in rheumatoid arthritis， it is considered that the mechanism in Chinese medicine of "marrow reduction， flesh flaccid， collaterals blocked" ultimately leads to bone destruction， is similar to that in the western medicine of abnormal differentiation of osteoclasts， high expression of nuclear factor-κB receptor activator of ligand， and abnormal expression of inflammatory factors. This point of view may provide a more comprehensive and scientific understanding of the key pathogenic mechanism of bone destruction in rheumatoid arthritis.
