Objective To identify significantly differentially expression of rat by genes chip,try to find out the initiating factors and molecular mechanisms that oxidative stress originate or strengthen the steriod-induced necrosis of femoral head(SINFH).Methods Twenty Wistar rats were dived into experimental group and control group randomly.The rats were injected intraperitoneally whith endotoxin,and then injected intramuscularly with high-dose methylprednisolone or saline in experimental group and control group respectively.The mRNA was extracted from the femoral head of rats inevery group,and the cDNA probes were obtained by inverse transcript,and then carried out microarray detection.The quantitative RT-PCR was used to confirm the results of the microarray.Results Histopathological findings revealed that the experimental group rats had femoral head necrosis,trabecular bone disorders,thinning,bone cell necrosis,and the rate of empty lacunae increased,and in control group no femoral head osteonecrosis was found.Total of 27 differentially expressed genes were found,and of which 4 genes(COX6A2,COX4I2,SOD3,and DUSP1)were significantly different.The expression of these 4 genes were down-regulated.The functions of these four genes involved in inhibition of reactive oxygen species(ROS)generation,accelerated removal of ROS and protection tissue from oxidative damage and so on.Conclusion The expression of oxidative stress-related genes in SINFH of rats exist change.COX6A2,COX4I2,SOD3,and DUSP1 are key genes in process of oxidative stress originate or strengthen the SINFH.

Objective: To observe the clinical effect of massage combined with warm acupuncture and moxibustion on primary frozen shoulder. Methods: From April 2018 to April 2019, 30 patients with primary frozen shoulder admitted and treated in Wenzhou Hospital of Traditional Chinese Medicine were selected in theresearch.According to different admission time, they were divided into observation group and control group, with 15 patients in each group.The control group was treated with warm acupuncture and moxibustion, while the observation group was combined with massage.The total effective rate and VAS pain score after treatment were compared and observed. Results: The total effective rate in the observation group was 93.33%, which was higher than 73.33% in the control group (χ²=3.294, P<0.05). The VAS score of the observation group was (1.05±0.22)points after treatment, which was lower than (3.13±0.43)points of the control group, the difference between the two groups was statistically significant(t=2.493, P=0.000). Conclusion Massage combined with warm acupuncture and moxibustion in the treatment of primary frozen shoulder is more effective than the single treatment method, which can relieve the pain of patients and is a safe and effective treatment.
