Objective:To evaluate the effects of peroneal osteotomy combined with arthroscopic knee debridement on perioperative indexes, X-ray indexes, Japanese Orthopaedic Association Assessment score (JOA score), American Hospital for Special Surgery knee score (HSS score) and complication rate of patients with knee osteoarthritis.Methods:A prospective research method was adopted. A total of 110 patients with knee osteoarthritis who were admitted to Chengde Central Hospital from April 2016 to April 2021 were selected as the research objects and divided into the control group (55 cases), the combined group (55 cases) by random number table method. The control group underwent arthroscopic debridement of the knee joint. On the basis of the control group, the combined group was combined with fibula osteotomy. The control group and the combined group were followed up for 6 months after operation. The perioperative indicators, score of JOA before and after 1 month of treatment, X-ray indicators, score of HSS before and after 6 months of treatment, and the incidence of complications during the follow-up period were compared between the control group and the combined group.Results:The operation time of the combined group was longer than that of the control group: (84.36 ± 14.64) min vs. (75.88 ± 12.86) min; compared with before operation, 1 month after operation, the scores of swelling, pain while up and down stairs, walking pain, joint range of motion were increased in the control group and the combined group, and the combined group was higher than the control group: (8.35 ± 0.73) points vs. (6.74 ± 0.67) points, (15.05 ± 1.74) points vs. (13.96±1.66) points, (21.75 ± 2.07) points vs. (18.58 ± 1.73) points, (27.59 ± 3.25) points vs. (25.74 ± 2.83) points; the femoral tibial angle and the range of motion of the knee joint in the control group and the combined group were increased, and the combined group was greater than the control group: (1.94 ± 0.60)° vs. (3.02 ± 0.67)°; the scores of stability, flexion deformity, muscle strength, range of motion, function, and pain in the control group and the combined group increased, and the combined group was higher than the control group: (8.62 ± 0.86) points vs. (6.89 ± 0.78) points, (7.86 ± 0.96) points vs. (6.27 ± 0.68) points, (7.79 ± 0.62) points vs. (6.95 ± 0.57) points, (14.95 ± 2.60) points vs. (12.48 ± 2.33) points, (17.46 ± 2.21) points vs. (14.59 ± 1.76) points, (24.83 ± 3.25) points vs. (18.59 ± 2.57) points, the difference was statistically significant ( P<0.05). During the following up period, there were no significant differences in the incidences of osteofascial compartment syndrome, neurovascular injury, intraarticular adhesion and incision infection between the two groups ( P>0.05). Conclusions:The operation time of fibular osteotomy combined with arthroscopic debridement of knee joint in patients with knee osteoarthritis was longer, but fibular osteotomy combined with arthroscopic debridement of the knee joint can reduce the valgus of the patient and improve the range of motion of the joint. It could effectively reduce the degree of pain and improve the function of knee joint, and the safety was good, with good therapeutic effect.

Members of genus Acanthamoeba are widely distributed in the environment. Some are pathogenic and cause keratitis and fatal granulomatous amoebic encephalitis. In this study, we isolated an Acanthamoeba CJW/W1 strain from tap water in Wuxi, Jiangsu Province, China. Its 18S rDNA was sequenced and a phylogenetic tree was constructed. The isolated cysts belonged to morphologic group II. Comparison of 18S rDNA sequences of CJW/W1 strain and other isolates showed high similarity (99.7%) to a clinical isolate Asp, KA/E28. A phylogeny analysis confirmed this isolate belonged to the pathogenic genotype T4, the most common strain associated with Acanthamoeba-related diseases. This is the first report of an Acanthamoeba strain isolated from tap water in Wuxi, China. Acanthamoeba could be a public health threat to the contact lens wearers and, therefore, its prevalence should be monitored.

Adipokines play an important role in judging the severity and prognosis of coronary heart disease. In recent years, a series of studies have further proved the correlation between adipokines and coronary heart disease. Adipokines can be included in the risk stratification of patients with coronary heart disease and guide the formulation of clinical diagnosis and treatment strategies, and may become a potential therapeutic target of coronary heart disease. This paper mainly summarizes the role of adipokines in the clinical diagnosis and treatment of coronary heart disease.

Previous work has demonstrated that the sensitization of spinal neurons and microglia is important in the development of pain behaviors induced by BmK I, a Na channel activator and a major peptide component of the venom of the scorpion Buthus martensi Karsch (BmK). We found that the expression of P2X7 receptors (P2X7Rs) was up-regulated in the ipsilateral spinal dorsal horn after BmK I injection in rats. P2X7R was selectively localized in microglia but not astrocytes or neurons. Similarly, interleukin 1β (IL-1β) was selectively up-regulated in microglia in the spinal dorsal horn after BmK I injection. Intrathecal injection of P2X7R antagonists largely reduced BmK I-induced spontaneous and evoked pain behaviors, and the up-regulation of P2X7R and IL-1β in the spinal cord. These data suggested that the up-regulation of P2X7Rs mediates microglial activation in the spinal dorsal horn, and therefore contributes to the development of BmK I-induced pain.
