ObjectiveTo summarize the progress of research related to the surgical treatment of recurrent patellar dislocation by peripatellar osteotomy in clinical practice, in order to provide reference for clinical treatment. MethodsThe recent literature on peripatellar osteotomy for recurrent patellar dislocation at home and abroad was reviewed, and the bony structural abnormalities, imaging diagnosis, and treatment status were summarized. ResultsAbnormalities in the bony anatomy of the lower limb and poor alignment lead to patellofemoral joint instability through the quadriceps pulling force line and play an important role in the pathogenesis of recurrent patellar dislocation. Identifying the source of the deformity and intervening with peripatellar osteotomy to restore the biomechanical structure of the patellofemoral joint can reduce the risk of soft tissue surgical failure, delay joint degeneration, and achieve the target of treatment. ConclusionIn the clinical diagnosis and treatment of recurrent patellar dislocation, the factors causing patellofemoral joint instability should be comprehensively evaluated to guide the selection of surgery and personalized treatment.
Objective To clarify the role of gastrokine 1 in the process of formation and development of gastric cancer. Methods The expressions of gastrokine 1 in gastric cancer and paracancerous tissues of 52 patients with gastriccancer were detected by real-time fluorescence quantitative polymerase chain reaction （RT-PCR） and immunohistochemistry. Meanwhile the relationship of the expression level of gastrokine 1 with clinicopathologic characteristics were analyzed. Results The expression levels of gastrokine 1 gene and protein in the gastric cancer tissues were significantly lower than those in the paracancerous tissues （P＜0.01）. No significant relationship was found between expression of gastrokine 1 gene and clinicopathologic features including tumor location， depth of invasion， differentiation， lymph node metastasis， tumor stage， gender， age， and preoperative peripheral blood CEA and CA19-9 levels （P＞0.05，respectively）. What’s more， the expression level of gastrokine 1 gene in gastric cancer tissues of Helicobacter pylori （HP）-positive patients was lower than that in the negative ones （P＜0.05）. Conclusions Gastrokine 1 may play a significant role as an anti-oncogene in the process of the formation and development of gastric cancer. Its effect may become weak due to HP infection in gastric cancer patients.
ObjectiveTo systematically evaluate the efficacy and safety of traditional Chinese medicine (TCM) compound in treating pulmonary nodules, providing basic evidence-based medical evidence for TCM intervention in pulmonary nodules. MethodsComputer search of PubMed, CNKI, Wanfang, VIP, and SinoMed was conducted to select randomized controlled trials (RCTs) of TCM compound intervention in pulmonary nodules, with the retrieval time from the inception to November 29, 2023. The Cochrane bias risk assessment tool was used to evaluate the quality of the included studies, and Review Manager 5.4 was used for Meta-analysis. ResultsA total of 18 RCTs were included, covering 8 provinces across the country, with a total sample size of 1301 patients. The TCM compounds used in the included studies all incorporated the method of dissolving phlegm and dissipating nodules. There was a high risk of bias uncertainty in the included studies. Meta-analysis results suggested that TCM compound could significantly reduce the diameter of pulmonary nodules [MD=−1.41, 95%CI (−1.70, −1.13), P<0.001], decrease the number of nodules [MD=−0.37, 95%CI (−0.73, −0.01), P=0.05], alleviate clinical symptoms [MD=−4.84, 95%CI (−6.04, −3.64), P<0.001], and improve lung function [forced expiratory volume in one second (FEV1), MD=0.55, 95%CI (0.09, 1.01), P=0.02; FEV1/forced vital capacity, MD=6.12, 95%CI (4.47, 7.78), P<0.001]. However, there was no statistically significant difference in the probability of malignancy between the experimental group and the control group [MD=−0.01, 95%CI (−0.01, 0.00), P=0.09]. ConclusionTCM compound can significantly reduce the diameter of pulmonary nodules, decrease the number of nodules, alleviate clinical symptoms, and improve lung function, but future multicenter, large-sample, high-quality RCTs are still needed to further explore and verify this conclusion.
