Objective To discuss influence and curative effect observation of sodium hyaluronate on serum matrix metalloproteinase-9,12 and 13 (MMP-9, 12 and 13) levels of patients with knee osteoarthritis (OA). Methods Selected 70 cases of patients with knee OA, and divided into observation group (n=35 cases) and control group (n=35 cases) in accordance at random. The patients in two groups were given oral 75 mg diclofenac sodium enteric capsules , once a day for 5 weeks. The patients in observation group were additionally given 2 mL sodium hyaluronate , injected into in-tra-articular, once a week, for 5 weeks. Excepted for sodium hyaluronate injection fluid, the patients in control group were given the same medical treatment as that in observation group. The changes of serum MMP-9 , 12 and 13 levels between the two groups before and after medical treatment were observed , and the clinical curative effect and untoward effect was compared as well. Results After 5 weeks’ treatment, the serum MMP-9, 12 and 13 levels of patients in two groups were declined more significantly than before with different degrees (P<0.05 or P<0.01), and the declining rate of patients in observation group was much higher than that in control group (P<0.05). The clinical good and excellent rate with in observation group(85.71%) was much higher than that in control group (62.86%)(χ2=4.79,P<0.05). 9 and 11 cases of untoward effect were appeared between control group and observation group respectively with light symp-tom, and after comparing the occurrence rates of untoward effect of patients in two groups, with no statistical differ-ences (χ2=0.28,P>0.05). Conclusion Sodium hyaluronate has favorable curative effect on patients with knee OA, whose mechanism of action has close effect on reducing serum MMP-9 ,12 and 13 levels.

Objective:To evaluate the effect of remote endarterectomy in the treatment of complex lower extremity ischemia.Methods:Twenty-one limb ischemic patients underwent remote endarterectomy in Beijing Hospital from Sep 2016 to Feb 2020. Clinical data including general condition, the lesion of lower artery before operation and follow up outcomes were collected. Then the patency rate and limb salvage rate were calculated.Results:The technique success rate was 71.4% (15/21). The 3, 6, 12 month patency rate were 93.3%, 85.6% and 74.1%, respectively. The 1-year limb salvage rate was 93.3% (14/15). In the 6 patients converted to artificial vessel bypass, the 3,6,12 months patency rates were 76.7%, 66.7% and 46.8%, respectively. The 1-year limb salvage rate was 66.7%.Conclusions:Remote endarterectomy of the lower extremity artery is an alternative option in the treatment of complex ischemic lesions of the lower extremity artery, other than artificial vessel bypass.
