ABSTRACT

OBJECTIVE@#To observe the clinical efficacy of intercondylar fossa plasty in preventing intercondylar fossa impingement syndrome after high tibial osteotomy.@*METHODS@#From August 2018 to August 2020, 84 patients with inverted knee osteoarthritis were treated by arthroscopy combined with high tibial osteotomy, and were divided into two groups with 42 cases in each group according to different surgical methods. In the intercondylar fossa plasty group, there were 13 males and 29 females, age ranged from 52 to 67 years old with an average of(58.27±4.32) years old, and arthroscopic intercondylar fossa plasty was performed first, and then high tibial osteotomy. In the arthroscopic cleansing group, 16 males and 26 females, age ranged from 50 to 71 years old with an average of (59.02±5.14) years old, underwent arthroscopic cleansing and then high tibial osteotomy. Postoperative treatment was evaluated using visual analogue scale(VAS), hospital for special surgery (HSS) score for the knee, and the occurrence of intercondylar percussa impingement.@*RESULTS@#All 84 patients were followed up, the duration ranged from 12 to 18 months with an average of (14.1±1.6) months. The VAS and HSS score of knee joint at 6, 12 and 18 months after surgery were significantly improved compared with preoperative period, and there was no significant difference between the two groups (P>0.05), but the incidence of intercondylar fossa index and intercondylar fossa impact between the two groups was significantly compared 18 months after surgery (P<0.05).@*CONCLUSION@#Intercondylar fossa plasty can effectively prevent the incidence of intercondylar fossa impact after high tibial osteotomy, and has a more significant effect on postoperative knee pain and function improvement.

ABSTRACT

OBJECTIVE@#To investigate the clinical effect of high tibial osteotomy combined with arthroscopic lateral retinacular release in the treatment of knee varus osteoarthritis.@*METHODS@#From October 2017 to April 2019, a retrospective analysis was performed on 43 patients with knee varus osteoarthritis and lateral patellar compression syndrome treated by high tibial osteotomy combined with arthroscopic lateral retinacular release. There were 15 males and 28 females, aged 53 to 72(62.05±5.17) years. The visual analogue scale(VAS), Lysholm, and the knee range of motion were used to evaluate knee pain and functional recovery before operation, 2 weeks, 3 months and 12 months after operation. And the congruence angle (CA), patellar tilt angle (PTA), and femala-tibial angle (FTA) were measured respectively before and 12 months after operation to evaluate the congruence of patellar joint, and the improvement of line of gravity of lower limb.@*RESULTS@#All 43 patients were followed up for more than 12 months, with a follow-up time of 14 to 28 (19.60±4.50) months. The VAS scores decreased from 6.65±0.65 before operation to 2.16±0.95, 0.51±0.77 and 0.33±0.64 at 2 weeks, 3 months and 12 months after operation, and the difference was statistically significant (@*CONCLUSION@#High tibial osteotomy combined with arthroscopic lateral retinacular release can relieve weight-bearing pain in frontal axis and improve the function of knee in sagittal axis.

ABSTRACT

The traditional Chinese medicine (TCM) concept that "different diseases may share the same TCM syndrome" is a unique theory explaining the relationship between diseases and TCM syndromes, which originally means that different diseases sharing the same TCM pathogenesis may develop the same syndrome. It accords with the theory of treatment based on syndrome differentiation. In clinical practices, this concept explains why the same herbal formula can be used to treat different diseases. With the development of a novel strategy to integrate the disease diagnosis and TCM syndrome differentiation, the meaning of "different diseases may share the same TCM syndrome" has also changed. It means that different diseases share the same TCM pathogenesis during their progression may show the same syndrome. Osteonecrosis of the femoral head (ONFH), hip osteoarthritis (HOA), and hip rheumatoid arthritis (HRA) are three different diseases that occur in the bones, cartilage, and synovium of the hip joint, respectively. However, they share similar clinical symptoms and TCM symptoms if they had progressed to the end-stage. In the end-stage of the disease, hip pain, restricted activity, signs of waist and knee pain, and weakened walking function, whether it is symptoms or signs or TCM syndromes, all show their similarities, reflecting the concept of different diseases may share the same TCM syndrome. This article discusses the similarity of the three diseases from the aspects of syndrome characteristics, radiographic findings, syndrome differentiation, etiology and pathogenesis, as well as clinical treatments. We found that, in addition to similar clinical signs and symptoms, the three hip osteoarthropathies in the end-stage see articular cartilage degeneration, joint space stenosis, joint effusion, synovial thickening, bone hyperplasia, and subchondral bone cystic degeneration, etc. similar X-ray performance, kidney sperm, bone marrow, only kidney sufficiency, muscles and bones can be filled with bone marrow, liver blood, main muscles, liver and blood are sufficient to support the muscles and bones, and the disease is in the advanced stage, ONFH, HOA and HRA are closely related to liver and kidney dysfunction. Insufficient liver and kidney, meridian muscle, and bone malnutrition are three common pathological mechanisms of late hip bone disease. Deficiency, waist and knee weakness, and weakness in walking have also become common symptoms. It not only provides a theoretical basis for the "same syndrome",but also helps the differential diagnosis of "different diseases", improves the fracture level of hip diseases, and enriches the connotation of "different diseases sharing the same syndrome" in Chinese medicine.

ABSTRACT

OBJECTIVE@#To evaluate the cartilage regeneration in the knee joint by arthroscopy after high tibial osteotomy.@*METHODS@#Eleven patients were included in the study who were treated with high tibial osteotomy and underwent microscopy when the internal fixation was unloaded from September 2017 to September 2019. Among them, there were 2 males and 9 females, aged from 55 to 64 years old. The internal and external compartment pictures of the knee were taken before and after surgery of removing the internal fixation and the International Cartilage Repair Society (ICRS) grading systerm was used to evaluate the degree of cartilage damage on the medial and lateral femoralcondyles and tibial plateau. The Westrn Ontarioand Mcmaster Universities osteoarthritis index (WOMAC) and the weight bearing line (WBL) were used to evaluate the function of the knee and the alignment of the lower limb.@*RESULTS@#All 8 patients were followed up for more than 12 months, ranging from 12 to 22 months. The degenerated cartilage of the medial femoral condyle and medial tibial plateau was covered by newly regenerated cartilage. WOMAC score decreased from 102-127 to 41-52 and WBL was improved from 17%-34% to 58%-64%. All incisions healed in stageⅠ, and no complications such as internal fixation rupture and infection occurred during and after the operation.@*CONCLUSION@#High tibial osteotomy can relieve the pain of the knee and the dysfunction by adjusting lower limb alignment, and the degenerated cartilage could be regenerated in the medial femoral condyle and medial tibial plateau.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the changes of autophagy in ischemic myocardium of rats treated with fasudil for inhibiting Rho kinase.</p><p><b>METHODS</b>The hearts isolated from male Sprague-Dawley rats were subjected to 30 min of occlusion of the left anterior descending artery followed by 120 min of reperfusion with or without treatment with fasudil or fasudil+Wort. The left ventricular hemodynamics were continuously recorded, and the coronary effluent was collected during the reperfusion to determine lactate dehydrogenase (LDH) levels. The mRNA expressions of autophagy-related genes Atg5 and Beclin1 and apoptosis-related genes bax and bcl-2 were detected by RT-PCR, and the protein expression of caspase-3 was detected by Western blotting.</p><p><b>RESULTS</b>Compared with I/R group, fasudil significantly improved the left ventricular developed pressure, maximal rise/fall rate of left ventricular pressure and rate pressure product, reduced LDH release during reperfusion, increased Atg5 and Beclin1 mRNA expression and the ratio of Bcl-2/Bax, and lowered caspase 3 protein expression. The autophagy inhibitor Wort significantly attenuated the effect of fasudil in the rat hearts.</p><p><b>CONCLUSION</b>Fasudil treatment for inhibiting Rho kinase promoted autophagy in ex vivo rat heart to protect against myocardial ischima-reperfusion injury possibly by reducing apoptosis of the cardiac myocytes.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the association of the expression of hypoxia-inducible factor 1α (HIF-1α) with microlymphatic vessel density(MLVD) and lymph node micro-metastasis in rectal cancer.</p><p><b>METHODS</b>The experimental group consisted of 40 middle-low rectal cancer specimens pathologically confirmed at the First Affiliated Hospital of Anhui Medical University between 2000 and 2003. Forty samples of normal tissues taken from the corresponding area around the cancer were used as the control group. Immunohistochemistry was used to detect HIF-1α expression and MLVD in both the tumor tissues and the adjacent normal tissues. Lymph node micrometastasis was ascertained using immunohistochemical staining with CK20.</p><p><b>RESULTS</b>In rectal cancer tissues, the HIF-1α expression was 77 386±14 911 and MLVD was 7.3±0.7, significantly higher than those in normal adjacent tissues(33 092±5877 and 0.3±0.2, both P<0.01). The HIF-1α expression was positively correlated with MLVD in rectal cancer(r=0.781, P<0.01). Thirty-one patients had no lymph nodes metastasis and 10 had micrometastasis. The HIF-1α expression and MLVD in specimens with lymph node micrometastasis was significantly higher than that in those without lymph node micrometastasis(P<0.05).</p><p><b>CONCLUSION</b>HIF-1α and MLVD play important roles in the development of rectal cancer,which may promote lymphatic micrometastasis in rectal cancer.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical efficacy of treatment on the cases of severe hallux valgus by the first metatarsal basal osteotomy combined with Chevron-Gerbert operation.</p><p><b>METHODS</b>From June 2004 to August 2008, 37 cases of severe hallux valgus (66 feet) underwent first metatarsal basal osteotomy combined with Chevron-Gerbert operation. There were 5 males (10 feet) and 21 females (38 feet), aged 21 - 76 years (mean 58 years). For all patients with follow-up, radiographic measurements of frontal and lateral position of foot were taken to measure the hallux valgus angle (HVA), the IMA (intermetatarsal angle) and the proximal articular set angle (PASA) preoperatively, postoperatively and in follow-up respectively. The measuring results were compared among the preoperative, the 6-week postoperative and the final follow-up. At the same time the patients were evaluated with the AOFAS Maryland score.</p><p><b>RESULTS</b>Of the original 37 patients, 26 patients (48 feet) were followed up. The mean durations of follow-up was 2.3 years (range from 1 to 4 years). At final follow-up, HVA corrected 25.6° ± 3.8°, IMA corrected 8.6° ± 2.4°, and PASA corrected 4.7° ± 4.2°. According to AOFAS rating system, 91.7% patients were rated as excellent or good with excellent in 15 patients (28 feet), good in 8 patients (16 feet), and fair in 3 patients (4 feet).</p><p><b>CONCLUSIONS</b>First metatarsal basal osteotomy combined with Chevron-Gerbert operation has good efficacy to the patients with severe hallux valgus. However there are disadvantages such as complexity relatively for multi-stage osteotomy and internal fixation.</p>
