Lysosomes are organelles that extensively exist in cells of animals and plants. The outer boundary of lysosomes is the unit membrane that surrounds high electron dense substances. The chief components of lysosomes are a variety of hydrolases that can hydrolyze many intracellular components including macromolcular substances produced by cell itself and organic substances that come from extracellular environment. Therefore, the function of lysosomes is to degrade exogenous materials (heterophagics) and endogenous materials (autophagies). Moreover, lysosomse play an important role in the physiologic, pathlogic, pharmacologic and immunologic processes. The present review describes the enzymes within the lysosomes and explains the morphology and function of the primary lysosomes.

Conclusion The therapy with small needle knife plus joints washing has good effect in treating knee osteoarthritis.

Objective To study microinflammatory status in patients of end-stage renal disease undergoing maintained hemodialysis (MHD) and the relationship between microinfl-ammatory status of end-stage renal disease and anemia, malnutrition, left ventricular function in maintained hemodialysis patients. Methods One hundred patients undergoing hemodialysis were divided into non-microinflammation group ( hs-CRP ≤ 3 mg/L) and microinflammation group ( hs-CRP > 3 mg/L) . The serum levels of hs-CRP, albumin, triglyceride ( TG) , total cholesterol(TC) , lipoprotein(a) [LP( a)] and serum creatinine ( SCr) were measured. The levels of hemoglobin (Hb) and hematocrit (Hct) were measured. The left atrial (LAD)and ventricular diameter(LVD) ,interventricular septum thickness (IVST) ,left ventricular posterior wall thickness (LVPW) ,left ventricular ejective fraction (EF), ratio of E/A were measured by color Doppler echocardiography, and left ventricular mass index (LVMI) was calculated. Blood pressure was measured in different 5 stages, and their relation were analysed. Results ①The levels of Hb, Hct, Alb in microinflammation group were lower than those in the control group(t =2. 83 ,P <0.01; t=2.34, P<0.05;t = 5.30,P <0.01, respectively), the level of LP(a) was higher than that in the non-microinflammation group(t = 2. 68, P < 0. 05 ). ②The levels of LAD, LVD, LVPW, IVST, LVMI in the elevated microinflammation group were higher than those in the control group (P < 0.05), the levels of EF and E/A were lower than those in the non-microinflammation group ( P < 0. 05 ) .③ Blood serum hs-CRP concentration was negatively correlated with the level of Hb,Hct(r= -0. 283,P <0. 05;r = -0. 308,P <0.05;r = -0.387,P< 0. 01, respectively ) , and positively correlated with LP ( a ) ( r = 0.427, P < 0. 05 ) . Blood serum hs-CRP concentration was positively correlated with LVD,IVST,LVMI (P <0. 05) and negatively correlated with EF,E/A (P<0.05). ④hs-CRP, Hb, Hct, Kt/V, Alb, Lp(a) ,SBP and PP were risk factors of abnormal left ventricular structure and function. Conclusions In patients undergoing maintenance hemodialysis, the persistent increase of hs-CRP indicates the presence of microinflammation hs-CRP might.be a indicator of the anemia, nutrition status and left ventricular structure and function. Elevated hs-CRP is an independent risk factor of abnormal left ventricular structure and function.
