ObjectiveTo investigate the clinical effect of combined air pressure wave and oral glucosamine in the treatment of knee osteoarthritis. MethodsWe chose 200 patients with knee osteoarthritis treated in the Department of Rehabilitation between April 2013 and March 2015 as our research subjects. The patients were randomly divided into observation group and control group with 100 in each. The control group accepted conventional physical therapy, while the observation group underwent normal physical therapy in combination with air pressure wave and oral glucosamine treatment. We compared the two groups in terms of curative effects. ResultsThe total effective rate was not significantly different between the two groups (P＞0.05) , but in terms of efficiency rate, the observation group (85.0%) was significantly superior to the control group (73.0%) (P ＜ 0.05) . ConclusionCombined air pressure wave and oral glucosamine treatment for knee osteoarthritis is high efficient, which is worthy of being popularized.
ObjectiveTo investigate the clinical effect of arthroscopic microfracture surgery combined with oral glucosamine hydrochloride in the treatment of early knee osteoarthritis. MethodsWe retrospectively analyzed the clinical data of 172 patients with knee osteoarthritis treated between March 2007 and August 2013. The patients were divided into observation group (n=82) and control group (n=90) according to their treatment. Patients in the control group only underwent arthroscopic debridement and cartilage defect microfracture surgery, while those in the observation group underwent arthroscopic microfracture surgery combined with oral glucosamine hydrochloride. The Lysholm knee functional scores, the Lequesne index and X ray image were used to compare the clinical efficacy between the two groups. ResultsThe postoperative symptoms of both the two groups were significantly alleviated. The Lequesne index was not significantly different between the two groups before surgery, and 1 and 3 months after surgery (P>0.05), but it was significantly difference between the two groups 6, 12, 18 and 24 months after surgery (P<0.05). Before surgery, the Lysholm score was not significantly different between the two groups (P>0.05), and the score increased significantly after surgery in both the two groups (P<0.05). One and 3 months after surgery, the Lysholm score was not significantly different between the two groups (P>0.05), but it was significantly higher in the observation group 6, 12, 18 and 24 months after surgery. ConclusionArthroscopic microfracture surgery combined with oral glucosamine hydrochloride is effective in treating patients with early knee osteoarthritis, and the clinical efficacy becomes more significant with the time of treatment.
ObjectiveTo evaluate the efficacy and safety of glucosamine hydrochloride in the treatment of osteoarthritis. MethodsA total of 150 patients with osteoarthritis treated between April 2014 and April 2015 were randomly divided into control group and trial group with 75 in each. Patients in the trial group accepted oral glucosamine hydrochloride, while those in the control group were given diclofenac sodium. Lequesne index, total effective rate and the incidence of adverse reactions of both groups were calculated before and 2, 4, 6 and 8 weeks after treatment, and 2 weeks after drug withdrawal. ResultsIn both groups, Lequesne index started to decrease after 2 weeks of treatment (P<0.05), and reached the minimum value at treatment week eight (P<0.05). The Lequesne index 2 weeks after drug withdrawal was still obviously lower than that before treatment (P<0.05). There was no significant differences in the total effective rate at treatment week eight (83.1% for the control group and 80.9% for the trial group) or the total effective rate 2 weeks after drug withdrawal (80.0% for the control group and 79.4% for the trial group) between the control group and the trial group (P>0.05). The incidence of adverse reactions of the trial group (6.7%) was significantly lower than that of the control group (21.3%) (P<0.05). ConclusionGlucosamine hydrochloride is effective and safe in the treatment of osteoarthritis, which is suitable for long-term treatment.
ObjectiveTo observe the clinical effect of combined traditional Chinese and Western medicine in the treatment of knee osteoarthritis (KOA). MethodsA total of 180 KOA patients treated between January 2012 and June 2015 were randomly assigned to 3 groups: Chinese medicine group (group A, n=60) with acupuncture and irradiation therapy of specific electromagnetic wave therapeutic apparatus , western medicine group (group B, n=60) with oral glucosamine hydrochloride tablets and knee joint cavity injection of sodium hyaluronate, and integrated traditional Chinese and Western medicine group (group C, n=60) with treatments combining those in both group A and B. The treatment course was 6 weeks. The Western Ontario & McMaster University (WOMAC) osteoarthritis index score and total effective rate were evaluated before treatment and 2 weeks after treatment, end of treatment and 5 months after treatment. ResultsAfter treatment, the average improvement of WOMAC scores in the three groups was significantly different (P ＜ 0.05) . The total effective rate was 78.33% in group A, 83.33% in group B, and 91.67% in group C. The difference of total effective rate between group C and A, and between group C and B was statistically significant (P＜0.05) ; and it was also statistically significant between group A and B (P ＜ 0.05) . There were two cases of adverse reactions in group A, two in group B, and two in group C, and the reactions were all relatively mild without any serious adverse events. ConclusionsChinese medicine and western medicine are both effective and safe for the treatment of KOA. When they are combined, the effect is further enhanced with no increase of adverse reactions.
ObjectiveTo investigate the effect of arthroscopic debridement combined with oral glucosamine hydrochloride tablets in the treatment of knee osteoarthritis. MethodsSixty-two patients with knee osteoarthritis treated between January 2013 and April 2015 were chosen to be our research subjects. They were randomly divided into trial group (n=31) and control group (n=31). The control group was treated with arthroscopic debridement, and the trial group was given glucosamine hydrochloride tablets for treatment, apart from arthroscopic debridement. We evaluated the clinical effects by visual analogue scale (VAS) score and Lysholm knee joint function score before, and 1 week, 4 weeks, 3 months and 6 months after surgery. ResultsOne week after surgery, the VAS score and Lysholm knee joint function score were not significantly different between the two groups (P>0.05). Four weeks, 3 months and 6 months after surgery, the VAS score of the trial group was respectively 3.08±0.91, 2.46±0.87, and 1.45±0.66, and was 5.47±1.02, 3.55±1.20, and 2.37±0.53 in the control group; the Lysholm score of the trial group was 80.55±2.24, 85.35±1.79, and 89.74±4.58, respectively, and of the control group was 72.55±4.47, 74.68±2.94, and 76.69±5.63. The VAS score and the Lysholm score of the trial group were both better than those of the control group (P<0.05). ConclusionArthroscopic debridement can alleviate the symptoms of knee osteoarthritis, and oral administration of glucosamine hydrochloride tablets after surgery has obvious effects.
ObjectiveTo investigate the clinical efficacy of glucosamine hydrochloride tablets in treating knee cartilage injury resulting from rheumatoid arthritis. MethodsWe selected 200 knee cartilage injury patients with rheumatoid arthritis treated in our hospital from January 2011 to January 2015 as the research subjects. They were divided into control group (n=98) and observation group (n=102) according to the time of admission. The control group was treated with conventional disease modifying anti-rheumatic drugs (DMARDs), while the observation group was treated with glucosamine hydrochloride tablets on the basis of DMARDs. The treatment effect was evaluated and compared between the two groups of patients 18, 36 and 54 weeks after the treatment. ResultsFifty-four weeks later, knee pain score of the observation group was better than that of the control group, and the difference was statistically significant (P ＜ 0.05) . The observation group had a lower Noyes evaluation level than the control group, and the difference was statistically significant (P ＜ 0.05) . Adverse reaction in the observation group was 3.92% and it was 3.06% in the control group, and the difference between the two groups was not statistically significant (P ＞ 0.05) . ConclusionGlucosamine hydrochloride tablets combined with conventional anti-rheumatic treatment is effective for knee cartilage injury caused by rheumatoid arthritis, which can promote cartilage repair, and it is worthy of clinical application.
ObjectiveTo observe the efficacy of self-behavior management combined with glucosamine hydrochloride for patients with early knee osteoarthritis. MethodsBetween October 2013 and March 2015, 240 patients with early knee osteoarthritis were randomly assigned to behavior therapy group (n=80) , drug treatment group (n=80) and combined treatment group (n=80) . Patients in the behavior therapy group were treated only by self-behavior management; patients in the drug treatment group were treated by glucosamine hydrochloride (0.48 g, three times per day); patients in the combined treatment group were treated by self-behavior management combined with glucosamine hydrochloride. The effect of treatment, adverse reactions, efficiency and expulsion rate were assessed 4, 8 and 12 weeks after treatment. ResultsThe Lequesne index and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) significantly decreased from week 4 when compared with week 0 after treatment in the combined treatment group, and there was a significant difference between the combined treatment group and single therapy group at week 8 and 12 (P ＜ 0.05) . The Lequesne index in the behavior therapy group and drug treatment group began to significantly decrease from week 8, and the WOMAC score significantly decreased from week 4 in the drug treatment group and from week 8 in the behavior therapy group. The efficiency increased with the treatment time prolonged in all three groups, but the efficiency in the combined treatment group was significantly higher than the single therapy group (P ＜ 0.05) . The shedding rates in the behavior therapy group, drug treatment group and combined treatment group were respectively 12.5%, 7.5% and 6.3%, without statistically significant difference (P ＞ 0.05) . The adverse reaction rate was low in all the three groups. ConclusionThe self-behavior management combined with glucosamine hydrochloride is an effective, safe and well-tolerated treatment for early knee osteoarthritis.
ObjectiveTo compare the clinical efficacy of glucosamine hydrochloride and diacerein for patients with knee osteoarthritis and the MRI variation. MethodsBetween January and June 2014, 90 patients with knee osteoarthritis were randomized into three groups: group A (treated by glucosamine hydrochloride), group B (treated by diacerein) and group C (treated by both glucosamine hydrochloride and diacerein). The score of Western Ontario and McMaster Universities (WOMAC) index of osteoarthritis, MRI cartilage injury Recht grading and the curative effects for bone marrow edema, joint cavity effusion and meniscus injury were compared before and after the treatment. ResultsThe scores of WOMAC after treatment in all the groups were improved, while the therapeutic effect of group C lasted longer when medical treatment suspended. The number of articular surface with different degrees of cartilage injury showed no statistically significant change in all three groups (P ＞ 0.05) . The state of bone marrow edema and joint cavity effusion were improved with a statistically significant difference in all groups (P ＜ 0.05) . Patients with lateral meniscus degeneration in group A and patients with medial meniscal tear in group B both increased with statistically significant differences (P ＜ 0.05) . However, in group C, patients with lateral meniscus degeneration or meniscal tear decreased with statistically significant differences (P ＜ 0.05) . ConclusionsThe treatment for osteoarthritis by glucosamine hydrochloride is effective, and the curative effect lasts longer when treated by both glucosamine hydrochloride and diacerein. Glucosamine hydrochloride ameliorates the bone marrow edema and joint cavity effusion. Treatment together with diacerein leads to a better therapeutic effect for patients with meniscus degeneration, yet further studies are needed to prove its effects in ameliorating cartilage injury.
Objective To access the protective effects of glucosamine hydrochloride capsules (OTL) on articular cartilage in osteoarthritis of rabbit. Methods Thirty-six New Zealand white rabbits were divided randomly into three groups (n=12): sham group (group A), anterior cruciate l igament transection (ACLT)/normal sal ine group (group B), and ACLT/ OTL group (group C). Rabbits in groups B, C received ACLT on the right knee. Rabbits in group A were not given ACLT ascontrol. Group C received a daily administration of OTL at a dose of 150 mg/kg of body weight for 12 weeks; in contrast, group B received normal sal ine at the same dose. All rabbits were sacrificed after 12 weeks. The right femoral condyle were removed and observed at pathologic changes with HE staining and graded by Mankin’s scale, the expression level of transforming growth factor β1 (TGF-β1) and interleukin 1β (IL-1β) were detected by immunohistochemical staining. Results All rabbits survived at the end of experiment and incision healed well. The gross observation showed that joint synovia increased and articular surface was smooth and integrity in group A; that ulcer was observed on the articular surface of group B; and that articular surface was smooth and integrity in group C. There were sigificant differences in articular cartilage scores between 3 groups (P lt; 0.05). The histological observation showed that the articular cartilage had normal structure and the cells arranged regularly in group A; that the articular cartilage became thin and the cells arranged irregularly in group B; and that the cells arranged with a clear layer and had regular shape in group C. The Mankin scores were 1.04 ± 0.13, 7.97 ± 0.12, and 2.81 ± 0.36 in groups A, B, and C, respectively; showing significant difference between 3 groups (P lt; 0.05). The result of immunohistochemistry showed that the expressions of TGF-β1 were 50.62 ± 1.51, 24.81 ± 1.28, and 41.57 ± 1.69 and the expressions of IL-1β were 13.12 ± 1.21, 62.53 ±2.37, and 30.67 ± 1.28; showing significant differences between 3 groups (P lt; 0.05). Conclusion A daily administration ofOTL at a dose of 150 mg/kg for 12 weeks can partially decrease the expression levels of IL-1β and increase the expression levels of TGF-β1, which delays the development of osteoarthritis.
ObjectiveTo discuss the effect of glucosamine-hydrochloride (Glu/Ch) in protecting and repairing the cartilage in blood-induced joint damage (BJD) in vivo. MethodsThirty-two adult New Zealand rabbits were randomly divided into 4 groups (n=8):high-dose Glu/Ch treated group (group A), low-dose Glu/Ch treated group (group B), positive control group (group C), and negative control group (group D). A joint bleeding model was established by blood injection into articular cavity in groups A, B, and C. Glu/Ch was given by gavage in groups A (250 mg/kg) and B (21.5 mg/kg) once a day for 8 weeks, and the same dosage of saline was given in groups C and D. The serum cartilage oligomeric matrix protein (COMP), serum chondroitin sulfate 846(CS846), and urinary C-terminal telopepide of type II collagen (CTX-II) were measured at 3 days, 7 days, 2 weeks, and 8 weeks after modeling. The expressions of cytokines such as interleukin 1β (IL-1β) and tumor necrosis factor α (TNF-α) in synovial fluid were analyzed by ELISA at 8 weeks after modeling. The expression of matrix metalloproteinase 13(MMP-13) was detected by immunohistochemistry. Alcian blue staining and Safranin-O staining were performed to calculate the percentage of the positive staining areas. The proteoglycan content was detected by semi-quantitative analysis in the articular cartilage. ResultsThe COMP concentration was significantly higher in groups A, B, and C than group D, and in groups B and C than group A at 3 days after modeling (P<0.05); no significant difference was found among groups A, B, and D at 7 days (P>0.05), and it was significantly lower in groups A, B, and D than group C (P<0.05); there was no significant difference among 4 groups after 2 and 8 weeks (P>0.05). Difference in CS846 concentration had no significance among 4 groups at each time point (P>0.05). The CTX-II concentration of groups A, B, and C was significantly higher than that of group D at each time point (P<0.05); it was significantly lower in group A than groups B and C at 7 days, 2 weeks, and 8 weeks (P<0.05). The TNF-α concentration of groups A and B was significantly higher than group D, and was significantly lower than group C at 8 weeks (P<0.05), but no significant difference was observed between groups A and B (P>0.05). The IL-1β concentration was significantly higher in group C than the other groups (P<0.05), and in group B than groups A and D (P<0.05), but there was no significant difference between groups A and D (P>0.05). The MMP-13 expression was significantly higher in group C than groups A, B, and D (P<0.05), in groups A and B than group D (P<0.05). A significant decrease in the area stained with Alcian blue and Safranin-O was observed in group C. There were significant differences in the percentage of the positive stained areas of Alcian blue and Safranin-O among 4 groups (P<0.05). The relative quantities of proteoglycan from small to large in order was groups C, B, A, and D, respectively, showing significant differences (P<0.05). ConclusionThe metabolism disorder of cartilage matrix and synovium inflammatory reaction can be observed in rat joint bleeding model. Glu/Ch has certain protective effect on the cartilage after BJD by down-regulating IL-1β, TNF-α, and MMP-13, as well as increasing proteoglycan content in the cartilage.
