Objective To investigate the clinical efficacy of mitral valve repair technique in the treatment of rheumatic mitral valve lesions. Methods The clinical data of patients diagnosed with rheumatic mitral valve lesions and undergoing mitral valve repair under extracorporeal circulation in our department from 2021 to 2022 were retrospectively analyzed. Results A total of 100 patients were collected, including 78 females and 22 males with an average age of 52 years. There were no secondary open heart or death in the whole group. Extracorporeal circulation time was 136.3±33.1 min, aortic cross-clamping time was 107.6±27.5 min, ventilator use time was 12.9±5.9 h, ICU stay was 2.6±1.4 d, and vasoactive medication use was 823.4±584.4 mg. Before and after the surgery, there were statistical differences in the left ventricular end diastolic diameter, left atrial end systolic diameter, effective mitral valve orifice area, shortening rate of left ventricular short axis, mitral E-peak blood flow velocity, mean mitral transvalvular pressure difference, mitral pressure half-time, and cardiac function graded by New York Heart Association (P＜0.05). While there was no statistical difference in left ventricular ejection fraction or left ventricular end-diastolic volume (P>0.05). Conclusion Overall repair of rheumatic mitral valve lesions can significantly improve the cardiac function and hemodynamics of the patients, and is a good choice for patients with rheumatic mitral valve lesions.

Objective To conclude the research progress of unicompartmental knee arthroplasty (UKA) in the treatment of elderly patients with knee osteoarthritis (KOA). Methods The literature on UKA at home and abroad in recent years was reviewed to summarize the clinical characteristics of elderly patients with KOA, perioperative management (including evaluating indications preoperatively, intraoperative prosthesis selection, postoperative complication management, etc). Results Through reasonable preoperative evaluation, prosthesis selection, and advanced perioperative management, for elderly patients with KOA who meet the indications, UKA can be considered. Compared with total knee arthroplasty, the incidence of postoperative complications in elderly patients undergoing UKA is lower, joint awareness is reduced, functional improvement and satisfaction are higher. Meanwhile, choosing appropriate prostheses and fixation methods can lead to a good survival rate. ConclusionUKA can provide a safe and effective treatment option for elderly patients with KOA within a certain range of indications.
ObjectiveTo discuss the effectiveness of operative treatments for different kinds of old injury of extensor tendon in zone II so as to choose the best surgical approach based on the classification of injury. MethodsBetween May 2006 and May 2014, 68 cases of old injury of extensor tendon in zone II were treated. Among them, there were 50 males and 18 females with an average age of 36 years (range, 18-52 years). The causes included contusion injury in 50 cases, avulsion injury in 11 cases, and burn injury in 7 cases. The left side was involved in 21 cases and the right side in 47 cases. The injured finger involved the index finger in 18 cases, the middle finger in 21 cases, the ring finger in 24 cases, and the little finger in 5 cases. The disease duration was 1.5 months to 1 year (mean, 6.75 months). The central slip of extensor was repaired directly in 32 patients who had normal passive motion. Side cross stitch (8 cases) or Littler-Eaton (10 cases) method was used in 18 patients who can not extend actively and passively. Tendon graft was performed in 11 patients with tendon defect. Joint release was given in 7 patients with contracture after burn injury. ResultsPrimary healing of incision was obtained in all cases. Sixty-eight cases were followed up 3-12 months (mean, 6.9 months). Three cases had tendon adhesion in varying degrees and suffered from pain, which was treated conservatively by functional exercise. Recurrence was observed in 2 cases, and extensor tendon was repaired again. According to total active motion (TAM) function assessment, the results were excellent in 52 cases, good in 11 cases, fair in 3 cases, and poor in 2 cases with an excellent and good rate of 92.6%. ConclusionAdaptive operation method for old injury of extensor tendon in zone II should be selected based on the type of injury. The results will be satisfactory if correct method is chosen.
Objective To compare the clinical efficacy between one-stage combined posterior and anterior approaches (PA-approach) and simple posterior approach (P-approach) for lower lumbar tuberculosis so as to provide some clinical reference for different surgical procedures of lower lumbar tuberculosis. Methods A retrospective analysis was made on the clinical data of 48 patients with lower lumbar tuberculosis treated between January 2010 and November 2014. Of them, 28 patients underwent debridement, bone graft, and instrumentation by PA-approach (PA-approach group), and 20 patients underwent debridement, interbody fusion, and instrumentation by P-approach (P-approach group). There was no significant difference in gender, age, course of the disease, and destructive segment between 2 groups (P>0.05). The operation time, blood loss, bed rest time, visual analogue scale (VAS) and complication were recorded and compared between 2 groups; American Spinal Injury Association (ASIA) grade was used to evaluate the nerve function, Bridwell classification and CT fusion criteria to assess bone fusion, erythrocyte sedimentation rate (ESR) to evaluate the tuberculosis control, and Oswestry disability index (ODI) to estimate lumbar function. Results The operation time, blood loss, and the bed rest time of the P-approach group were significantly less than those of the PA-approach group (P<0.05). Iliac vessels rupture was observed in 1 case of the PA-approach group and sinus tract formed in 2 cases of the P-approach group. The patients were followed up 13-35 months (mean, 15.7 months) in the PA-approach group and 15-37 months (mean, 16.3 months) in the P-approach group. At last follow-up, common toxic symptom of tuberculosis disappeared and the ASIA scale was improved to grade E. The VAS score and ESR at 1 year after operation and last follow-up, and ODI at last follow-up were significantly improved when compared with preoperative ones in 2 groups (P<0.05), but there was no significant difference between the 2 groups (P>0.05). During follow-up, no internal fixation broken, loosening, or pulling was found. Bridwell bone fusion rates were 89.29% (25/28) and 80.00% (16/20) respectively, and CT fusion rates were 96.43% (27/28) and 90.00% (18/20) respectively, showing no significant difference between the 2 groups (P>0.05). Conclusion Both one-stage PA-approach and simple P-approach could obtain good clinical efficacy. The PA-approach should be selected for patients with anterior-vertebral destroy, presacral or psoas major muscles abscess, and multiple vertebral body destroy, while P-approach should be selected for patient who could gain a good debridement evaluated by imaging before operation, especially for patients with middle-vertebral body destroy, block the iliac blood vessels and old patients.
ObjectiveTo systematically review the efficacy of Chinese medicine injection (CMI) for treating heart failure (HF).MethodsCNKI, WanFang Data, VIP, The Cochrane Library, PubMed, and EMbase databases were electronically searched from inception to January 2021 to identify randomized controlled trials (RCTs) on CMI for treating HF. Two reviewers independently screened literature, extracted data, and evaluated the risk of bias of included studies. Network meta-analysis was then performed by RevMan 5.2 software and Stata 16.0 software.ResultsA total of 47 studies were included involving 4 902 patients and 5 types of CMIs, including Shenmai, Shenfu, Yiqi Fumai (lyophilized), Shengmai, and Danhong injections. The results of network meta-analysis showed that the efficacy of combined CMIs was superior to conventional Western medicine alone. For the main efficacy, Shenmai, Shengmai, and Shenfu injections had significant advantages in improving the total clinical effectiveness. Shengmai, Shenmai, and Yiqi Fumai (lyophilized) injections were significantly more effective for reducing NT pro-BNP levels than other injections. Shenfu and Shengmai injections were significantly more effective for reducing BNP levels than other injections. Shenmai, Danhong and Shengmai injections were significantly more effective for improving the left ventricular ejection fraction than the other injections. These CMIs showed similar advantages for secondary efficacy indicators as for main efficacy indicators.ConclusionsThe combined 5 types of CMIs for treating HF can improve the clinical efficacy when compared with conventional Western medicine treatment. Shenmai injection, Yiqi Fumai injection (lyophilized), and Shengmai injection, which is part of Sheng Mai San, have clear advantages in terms of the overall curative effect or on individual indices.
ObjectiveTo review research progress in the anterolateral ligament (ALL) of knee, and provide a clinical reference for diagnosis and treatment of ALL injury.MethodsThe literature on the diagnosis and treatment of ALL injury was widely reviewed. The incidence, anatomy, biomechanics, injury mechanism, and treatment status of ALL were summarized.ResultsThe ALL contributes to the effect of controlling the internal rotation and anterior translation of the tibia, which affects the axial migration of the knee. ALL injury can be diagnosed according to the signs and MRI examination. Currently, no consensus exists for the surgical indications of ALL injury, but most surgeons tend to perform ALL reconstruction in patients requiring anterior cruciate ligament (ACL) reconstruction or revision surgery with higher pivot-shift tests. At present, various techniques have been used for ALL reconstruction, and there is no optimal technique. In addition, the long-term effectiveness of ALL reconstruction is unclear due to the lack of high-quality studies and long-term postoperative follow-up.ConclusionThe ALL contributes to maintaining knee stability, and the ALL reconstruction technique and its effectiveness still need further research.
Objective To investigate the cl inical directive significance of three-dimensional reconstruction of CT in treating mandibular angle hypertrophy. Methods Between March 2009 and January 2011, 18 patients with mandibular angle hypertrophy were treated using the three-dimensional reconstruction technology of CT. All patients were female, aged20-36 years with an average of 25 years. Eighteen patients included: 14 single mandibular angle hypertrophy, 3 mandibular angle hypertrophy with masseter hypertrophy, and 1 mandibular angle hypertrophy with bilateral asymmetry; 6 cases of ptosis of mandibular angle, 9 cases of prominent mandibular angle, and 3 cases of introversive mandibular angle. According to the types of mandibular angle hypertrophy, the surgical methods could be correctly chosen. The procedure was planned and simulated; the osteotomy l ine was marked and the osteotomy was measured on the workstations of three-dimensional reconstruction. Results No fracture of mandible occurred in the operation. Facial nerve temporary attack occurred in 1 case and recovered at 3 months after operation. All patients were followed up 6-12 months (mean, 7.6 months). After 6 months of operation, the effectiveness was satisfactory in 15 cases, basically satisfactory in 2 cases, and unsatisfactory in 1 case (bilateral asymmetry). Conclusion Based on three-dimensional reconstruction technology of CT, surgical design performed on the model will promote the accuracy of operation. Basically symmetrical appearances can be achieved with satisfactory results.
