Objective To observe the clinical effect of intra-articular injection of sodium hyaluronate combined with rehabilitation training in treatment of knee osteoarthritis, and their effects on β endorphin and substance P levels in plasma. Methods All 106 cases with knee osteoarthritis were divided into treatment group and control group. Treatment group were treated by intra-articular injection of sodium hyaluronate combined with rehabilitation training, and control group underwent rehabilitation training only. Knee joint function was evaluated using Lysholm scores before and six weeks after treatment, and at 3-month and 6-month follow-up. Meanwhile, the concentrations of β endorphin and substance P in plasma were tested in the two groups. Results Compared with pre- treatment, the Lysholm scores were obviously increased after 6-week treatment, at 3-month and 6-month follow-up in both groups, with more obvious increase in treatment versus control group (P＜0.01). The Lysholm scores were higher in treatment group than in control group (P＜0.01). The concentration of β endorphin in plasma was significantly increased, and the substance P concentration in plasma was decreased after treatment in both groups. There were also significant differences in concentrations of β endorphin and substance P in plasma between treatment group and control group (P＜0.01). Conclusions Intra-articular injection of sodium hyaluronate combined with rehabilitation training is effective in improving knee joint function in elderly patients, in relieving pain and in enhancing joint movement.

Objective To compare clinical effects between cilostazol(CLT)alone and cilostazol combined with pancreatic kininogenase(PK)on lower extremity arterial disease in diabetic patient(LEADDP).Methods Patients with LEADDP were randomly divided into 2 groups:single medication group or the control group(53 cases)and combination group or the treatment group(53 cases).Sugar-reducing medicines were given before and after treatment to keep a steady blood glucose level.The control group took CLT orally 100 mg each time,twice a day.Besides receiving the same dose of CLT,the treatment group took 120 tablet of PK on an empty stomach,three times a day,with the duration of 3 months.Clinical symptoms,ankle/brachial index(ABI),blood rheology,nailfold microcirculation,intimal medial thickness(IMT)and plaque thickness were compared between the 2 groups after treatment.Results Symptoms in both groups improved after treatment.ABI was elevated significantly compared to that before treatment(P<0.05)and the change was more obvious in combination group.The difference of ABI after treatment between the 2 groups had statistical significance(P<0.05).IMT of the right foot dorsal artery,and left and right posterior tibial artery increased significantly compared to that before treatment(P<0.05).Plaque thickness decreased compared to that before treatment(P<0.01)and the difference between before and after treatment in combination group was significantly greater than that in single medication group(P<0.05).Conclusion Cilostazol combined with pancreatic kininogenase has better clinical effects than cilostazol alone in treatment of patients with LEADDP.

Objective To investigate the protective effects of combination alprostadil and dexmedetomidine preconditioning treatment on skeletal muscle ischemia reperfusion and secondary lung injuries.Methods Sixty patients aged less than 70 years old undergoing unilateral lower extremity surgery were randomly assigned into four groups:control group(group A),dexmedetomidine group(group B),alprostadil group(group C)and combined treatment group(group D) with 15 cases in each.In group C and D,10 μg alprostadil was given from vein at 15 min before tourniquet inflation,in group B and D 1 μg/kg dexmedetomidine was given from vein at 10 min before tourniquet inflation,the equal volume of normal saline was infused in control group.The blood samples were drawn from vein and artery for blood gas analysises and determination of malondialdehyde(MDA) and human pulmonary surfactant specific protein D (SP D) concentrations at the time before oxygen inhalation(T1),2 h after tourniquet deflation(T2),6 h after tourniquet deflation(T3) respectively.Results In group B,C and D,the alveolar arterial oxygen pressure difference(PA-a DO2)and respiratory index(R1) were significantly lower than those in group A at T2(P＜0.05).PA-aDO2 and R1 were significantly higher at T3 than those at T1 in every groups(P＜0.05);In group B,C and D,MDA and SP D were significantly lower than those in group A at T2 and T3(P＜0.05).In group D,MDA and SP D were significantly lower than those in group B and group C at T3(P＜0.05).Conclusion Alprostadil and dexmedetomidine are infused from vein preconditioning can attenuate the damages of skeletal muscle ischemia reperfusion and secondary lung injuries.The combination of alprostadil with dexmcdetomidine can produce stronger effects.

BACKGROUND:Skeletal muscle fiber damage that is induced by prolonged or high-intensity exercise directly cause muscle injury. OBJECTIVE:To propose the existence of a relationship between delayed onset muscle soreness and muscle satel ite cel s after skeletal muscle injury from the objective reality. METHODS:A retrieval of CNKI and PubMed databases was done for relevant literature published from February 1961 to February 2015 using the keywords of“delayed onset muscle soreness;skeletal muscle injury;satel ite cel s, skeletal muscle;myogenic regulatory factors”in Chinese and English, respectively. Final y, 59 articles were included to explore the mechanism of skeletal muscle injury accompanied by delayed onset muscle pain. RESULTS AND CONCLUSION:Skeletal muscle micro-injury mainly refers to ultrastructural destroy and metabolic disorders, involving muscle cel membrane, cytoskeleton, sarcomere and mitochondria, thereby leading to skeletal muscle contraction dysfunction that is often accompanied with delayed onset muscle soreness. Eccentric exercise can cause the severest microdamage to the skeletal muscle fibers. The occurrence of delayed onset muscle soreness can stimulate the secretion of growth factors from skeletal muscle satel ite cel s to a certain extent, and the time series of delayed onset muscle soreness triggered by sustained high-intensity eccentric exercise has a certain correlation with the time series of the proliferation of skeletal muscle satel ite cel s.
