ABSTRACT Introduction: Total internal arthroscopic anterior cruciate ligament reconstruction is one of the new technologies in recent years. The main advantage is the need for only one tendon for the surgical procedure. Objective: Compare the clinical effects of total internal and traditional anterior cruciate ligament reconstruction techniques. Methods: From January 2019 to January 2022, the clinical data of 45 patients with anterior cruciate ligament reconstruction were retrospectively analyzed, including 32 males and 13 females aged 18-33 years, mean of 24.2 ± 3.3 years. Total internal reconstruction was performed in 22 cases (total internal group) and traditional reconstruction in 23 cases (traditional group). The two groups recorded and compared the time of injury, duration of surgical procedure, postoperative VAS score, and recovery of knee function. The International Knee Literature Committee (IKDC) and the Lysholm scoring system were used to evaluate clinical efficacy. Results: 45 patients were followed for 14 to 18 months, mean (15.4 ± 1.3) months. There were no significant differences between the two groups in time between operation and injury, duration of operation, IKDC, and Lysholm score of the affected knee at the last follow-up. However, there were significant differences in the VAS score on day one, day three, day seven, two weeks, and one month after the operation (P < 0.05), with no significant difference at three months, six months, and one year after the operation. Conclusion: The effect of total internal reconstruction of the anterior cruciate ligament is equivalent to that of traditional methods, with less postoperative pain, making it the ideal choice for this treatment. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
RESUMO Introdução: A reconstrução artroscópica interna total do ligamento cruzado anterior é uma das novas tecnologias dos últimos anos. A principal vantagem é a necessidade de apenas um tendão para o procedimento cirúrgico. Objetivo: Comparar os efeitos clínicos da técnica interna total e da técnica tradicional na reconstrução do ligamento cruzado anterior. Métodos: Entre janeiro de 2019 a janeiro de 2022, os dados clínicos de 45 pacientes com reconstrução do ligamento cruzado anterior foram analisados retrospectivamente, incluindo 32 homens e 13 mulheres, com idades entre 18-33 anos, média de 24,2 ± 3,3 anos. A reconstrução interna total foi realizada em 22 casos (grupo interno total) e a reconstrução tradicional em 23 casos (grupo tradicional). O tempo da lesão, duração do procedimento cirúrgico, escore de VAS pós-operatório e recuperação da função do joelho dos dois grupos foram registrados e comparados. O Comitê Internacional de Literatura de Joelho (IKDC) e o sistema de pontuação de Lysholm foram utilizados para avaliar a eficácia clínica. Resultados: 45 pacientes foram acompanhados durante 14 a 18 meses, média de (15,4 ± 1,3) meses. Não houve diferença significativa entre os dois grupos no tempo entre a operação e a lesão, a duração da operação, a pontuação do IKDC e Lysholm do joelho afetado no último acompanhamento. Porém, houveram diferenças significativas na pontuação do VAS no primeiro dia, terceiro dia, sétimo dia, duas semanas e um mês após a operação (P < 0,05), sem diferença significativa em três meses, seis meses e um ano após a operação. Conclusão: O efeito da reconstrução interna total do ligamento cruzado anterior é equivalente ao dos métodos tradicionais, com menor dor pós-operatória, sendo a escolha ideal para esse tratamento.

Se registraron y compararon el momento de la lesión, la duración del procedimiento quirúrgico, la puntuación postoperatoria de la VAS y la recuperación de la función de la rodilla de los dos grupos. Se utilizaron el Comité Internacional de Literatura sobre la Rodilla (IKDC) y el sistema de puntuación de Lysholm para evaluar la eficacia clínica. Resultados: 45 pacientes fueron seguidos durante 14 a 18 meses, con una media de (15,4 ± 1,3) meses. No hubo diferencias significativas entre los dos grupos en cuanto al tiempo transcurrido entre la operación y la lesión, la duración de la operación, la puntuación IKDC y Lysholm de la rodilla afectada en el último seguimiento. Sin embargo, hubo diferencias significativas en la puntuación de la VAS al primer día, al tercer día, al séptimo día, a las dos semanas y al mes después de la operación (p < 0,05), sin que hubiera diferencias significativas a los tres meses, a los seis meses y al año después de la operación. Conclusión: El efecto de la reconstrucción interna total del ligamento cruzado anterior es equivalente al de los métodos tradicionales, con menos dolor postoperatorio, lo que la convierte en la opción ideal para este tratamiento.

BACKGROUND:There is no literature about the treatment according to the mechanism of cervical spine injury classification, especial y for the treatment of extension type cervical fracture/dislocation with merger cases of posterior composite structure damage, whether simple anterior approach can meet the needs of the treatment has no detailed elaboration. This article may analyze from the aspect of cervical spine injury mechanism. OBJECTIVE:To observe the short-term effect of anterior cervical Cage-assisted fusion combined with locking titanium plate internal fixation for the treatment of extension type cervical fracture. METHODS:A retrospective analysis was performed in 15 extension type cervical spine fracture dislocation patients treated with decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation from June 2006 to March 2011 in the Department of Orthopedics, Xianning Central Hospital, including 10 cases of single segment injury and treatment, and five cases of multiple segment injury and treatment. Japanese Orthopaedic Association score and the neck disability index were compared before and after treatment;the cervical flexion and height were measured according to the antersposterior X-ray film taken before fixation, 1 week after fixation and final fol ow-up.RESULTS AND CONCLUSION:The patients were fol owed-up for 8-37 months. One case had Cage mild sinking and shift, and there was no internal fixation breakage or loosening in al the patients. Transient pharyngeal discomfort was observed in 11 patients. Compared with the preoperation, the Japanese Orthopaedic Association score, neck dysfunction index, fusion segment cervical flexion and fusion segment intervertebral disc height were significantly improved at 1 week after fixation and final fol ow-up (P0.05). The short-term effect of decompression anterior cervical intervertebral disc resection plus bone graft with cage-fusion locking titanium plate internal fixation for the treatment of extension-type cervical fracture is good.

Objective To investigate the epidemiology of BDV infection in Yili horses and Yili donkeys and to analyze phylogenetic source of BDV in Yili area, Xinjiang. Methods We established fluo- rescence quantitative nested RT-PCR to detect BDV p24 segment in peripheral blood mononuclear cells (PBMCs) of 518 Yili horses and 206 Yili donkeys in Yili area, Xinjiang. Positive products were validated by detecting BDV p40 segment and plasmid to preclude the contamination, and were sequenced to analyze the homology of gene sequence, amino acid sequence and phylogenetic tree. Results The positive rates of BDV infection in PBMCs of 518 Yili horses and 206 Yili donkeys were 0.97% and 1.94%, respectively. The results of BDV p40 segment verification were positive in all of the samples of BDV p24 positive. All the samples tested were not contaminated by plasmid. There was a homology of the gene sequence of positive PCR samples with strain He/80. And the gene sequence revealed more than 93% identical to H1766 and strain V. Conclusion Our study suggested BDV natural infection in Yili horses and Yili donkeys. The en- demic BDV had a high degree of identity to strain He/80.

Objective:To investigate the epidemics of Nipah virus(NiV)in Yili, Xinjiang Uygur Autonomous Region. Methods:One step real time reverse transcriptase polymerase chain reaction(real-time RT-PCR)was performed to detect the NiV N in peripheral blood mononuclear cells from 120 equines. Gene sequence and amino acid sequence were analyzed for positive products.Results:The positive rate of NiV N in PBMCs from 120 equines was 0%(0/120).Conclusion:The investigation do not support that NiV infection exist in Yili, Xinjiang Uygur Autonomous Region.
