OBJECTIVETo observe the clinical efficacy of treating middle-aged and aged patients with knee osteoarthritis (KOA) of yang-deficiency induced cold-damp syndrome (YDICDS) by ozone combined Fugui Gutong Granule (FGG).

METHODSUsing a prospective, randomized controlled clinical trial, 200 KOA patients of YDICDS were randomly assigned to four groups. i.e., the control group (Group A), the Chinese medicine treatment group (Group B), the ozone group (Group C), and the Chinese-r medicine treatment plus ozone group (Group D).Patients in Group A took Voltaren Tablet. Those in Group B took FGG. Those in Group C received ozone injection (10 -18 mL) from knee joint cavity at 25 mg/L, once weekly for 4 weeks in total. Those in Group D received injection from knee joint cavity and took FGG. The therapeutic course for all was one month. The efficacy was assessed using visual analogue scale (VAS) and Western Ontario MacMaster University Osteoarthritis index (WOMAC).

RESULTSThe VAS score was obviously lower in Group D than in Group B and Group A at 24 h and 1 week (P <0. 05). After one month of treatment, the VAS score was obviously lower in Group D than in Group A, B, and C (P < 0.05). After treatment the total integral of WOMAC was 25.34 +/- 2.12 in Group D, obviously lower than that in Group A (44.72 +/- 6.57), Group B (40.58 +/- 5.98), and Group C (38.53 +/- 5. 13), showing statistical difference (P <0.05). The pain score, the joint stiffness score, the score for daily activities were lower in Group D than in Group A (P <0.05). The cured and markedly effective rate was 76.0% in Group D, higher than that of Group A (25. 0%), Group B (25. 0%), and Group C (43.8%), respectively (P < 0.05).

CONCLUSIONOzone combined FGG had advantages in alleviating joint pain, and improving joint stiffness and daily activities of middle-aged and aged patients with KOA of YDICDS.

BACKGROUNDMedical ozone therapy system was reported to have certain effects on the treatment of severe hepatitis, but its mechanism is not very clear. One of the causes of death of severe hepatitis is complication of renal damage or hepatorenal syndrome. The present study aimed to observe effects of medical ozone therapy system on plasma renin activity (PRA), angiotensin II (AII), aldosterone (ALD), renal blood flow and renal function of patients with chronic severe hepatitis and explore mechanisms of medical ozone therapy in the treatment of severe hepatitis.

METHODSEighty-five cases with chronic severe hepatitis were randomly divided into ozone therapy group (43 cases) and control group (42 cases). The patients in the ozone therapy group were treated with basic treatments plus ozone therapy system. Basic autohemotherapy was used. One hundred milliliter venous blood was drawn from each patient, and was mixed with 100 ml (35 µg/ml) medical ozone and then was returned the blood to the patient intravenously, once every other day for 20 days. Only the basic treatments were given to the control group. PRA, AII, ALD, renal blood flow and damage to renal function of the two groups before treatment and 20 days after treatment were compared. Survival rates were also compared.

RESULTSTwenty days after the treatment, in ozone therapy group, PRA was (1.31 ± 0.12) ng·ml⁻¹·h⁻¹, AII (111.25 ± 17.35) pg/ml, ALD (251.31 ± 22.60) pg/ml, which decreased significantly compared with those before treatment (PRA (2.23 ± 0.13) ng·ml⁻¹·h⁻¹, AII (155.18 ± 19.13) pg/ml, ALD (405.31 ± 29.88) pg/ml, t = 4.67 - 14.23, P < 0.01), also lower than those of control group 20 days after the treatment (PRA (2.02 ± 0.11) ng·ml⁻¹·h⁻¹, AII (162.21 ± 15.32) pg/ml, ALD (401.20 ± 35.02) pg/ml, t = 4.97 - 15.61, P < 0.01); renal blood flow was (175.15 ± 28.20) ml/min, which increased compared with that before the treatment ((125.68 ± 21.25) ml/min) and was higher than that of control group 20 days after the treatment ((128.59 ± 23.15) ml/min, t = 4.78, 4.61, P < 0.01). Renal damage occurred in 2 cases (5%) in ozone therapy group, less than that in control group (9 cases, 21%) (χ² = 5.295, P < 0.05). Thirty-three cases (77%) in ozone therapy group vs. 16 cases (38%) in control group survived (χ² = 12.993, P < 0.01).

CONCLUSIONSBasic treatment plus medical ozone therapy for patients with chronic severe hepatitis could decrease PRA, AII and ALD levels significantly increase renal blood flow, prevent renal damage to certain extent and improve survival rate of the patients.

OBJECTIVES: Sepsis is a critical dysregulated host response with high mortality and current treatment is difficult to achieve optimal efficacy. Ozone therapy has been revealed to protect infection and inflammation-related diseases due to its role in antibiotic and immunoregulatory effect. Ozonated triglyceride is a key component of ozonated oil that is one of ozone therapy dosage form. However, the potential role of ozonated triglyceride in sepsis remains unclear. This study aims to explore the effect of ozonated triglyceride on septic mouse model and the molecular mechanism. METHODS: Intraperitoneal injection of lipopolysaccharide (LPS), cecal ligation and puncture (CLP) were applied to construct septic mouse model. The mouse serum was obtained for detection of cytokines, and lung tissues were collected for hematoxylin and eosin (HE) staining to evaluate the extent of lung injury in septic mouse with ozonated triglyceride treatment at different time and doses. The survival of septic mice was observed for 96 h and Kaplan-Meier analysis was used to analyze the survival rates. In addition, primary peritoneal macrophages and human acute monocytic-leukemia cell line (THP-1) were treated with inflammasome activators with or without ozonated triglyceride. The level of cytokines was detected by enzyme-linked immunosorbent assay (ELISA). The cleavage of caspase-1 and gasdermin-D (GSDMD) was detected by Western blotting. RESULTS: Ozonated triglyceride at different time and doses reduced the release of inflammasome-related cytokines [interleukin (IL)-1β and IL-18] (all P<0.05) but not pro-inflammatory cytokines such as IL-6 and tumor necrosis factor-α (TNF-α) in septic mice (all P>0.05). Ozonated triglyceride significantly improved the survival rate of septic mice and reduced sepsis-induced lung injury (all P<0.05). Ozonated triglyceride significantly suppressed the canonical and non-canonical activation of NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome (all P<0.05) but not affected absent in melanoma 2 (AIM2) and NLR family CARD domain-containing protein 4 (NLRC4) inflammasomes in vitro (all P>0.05). Ozonated triglyceride reduced the cleavage of caspase-1 and the downstream GSDMD. CONCLUSIONS Ozonated triglyceride presents a protect effect on sepsis lethality via reducing cytokines release and sepsis-related organ injury. The mechanism is that ozonated triglyceride specifically suppresses the activation of NLRP3 inflammasome. Ozonated triglyceride is a promising candidate for sepsis treatment.
