OBJECTIVETo evaluate the clinical efficacy of warm-needling moxibustion for knee osteoarthritis (KOA), and to explore its effects on isokinetic strength of lower limb muscle.
METHODSFifty cases of KOA were randomly divided into an observation group (25 cases) and a control group (21 cases), but 4 cases lost contact. The observation group was treated with warm-needling moxibustion at Dubi (ST 35), Neixiyan (EX-LE 4), Xuehai (SP 10), Liangqiu (ST 34), Yinlingquan (SP 9), Yanglingquan (GB 34), Weizhong (BL 40), Heyang (BL 55) and Fengshi (GB 31) for 40 min per treatment. The first 6 treatments were given once a day, and the last 6 treatments were given once every other day. 12 treatments were taken as one course, and totally 3-week treatment was given. No treatment was given in the control group for 3 weeks. The isokinetic strength of extensor muscle and flexor muscle, including the total work, absolute peak torque (aPT) and relative peak torque (rPT), and Western Ontario and McMaster Universities Arthritis Index (WOMAC), and comprehensive efficacy were observed and compared in the two groups.
RESULTSCompared before treatment, the total work, aPT and rPT of the extensor and flexor muscle increased significantly after treatment in the observation group (<0.01,<0.05), but the flextion/extention ratio was lowered (<0.05). In the control group, aPT and rPT of flexor muscle were reduced after treatment (<0.05,<0.01). The total work, aPT and rPT of the extensor muscle in the observation group were higher than those in the control group after treatment (<0.05,<0.01), but the flextion/extention ratio was lowered (<0.05). The item score and total score of WOMAC were reduced in the observation group after treatment (all<0.01), but no significant change was observed in the control group (all>0.05). The pain score, stiffness scores and total score of WOMAC in the observation group were lower than those in the control group (<0.01,<0.05); the score of daily function activities was declined in the observation group, but not significantly different from that in the control group (>0.05). The total effective rate was 88.0% (22/25) in the observation group.
CONCLUSIONSWarm-needling moxibustion could relieve pain, improve function and muscle balance, strengthen extensor and flexor muscle power, especially extensor, which has superior clinical efficacy.

【Objective】 To investigate the psychological status of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), and to analyze the effects of anxiety on the total National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) in patients in Ngari Prefecture of Tibet. 【Methods】 CP/CPPS patients treated during Oct.2019 and Oct.2021 were involved and divided into anxiety group and non-anxiety group. The non-anxiety group received routine drug treatment, while the anxiety group received drugs and psychological intervention. 【Results】 A total of 117 patients were involved, including 68 in the anxiety group and 49 in the non-anxiety group. There were no statistical differences between the two groups in terms of age, body mass index (BMI), marital status, smoking history, and education level (P>0.05). The total NIH-CPSI score in the anxiety group (18.53±3.47) was higher than that in non-anxiety group (15.67±3.33), which was mainly manifested by the increase of pain and decrease of quality of life scores. Further stratification of anxiety level revealed that quality of life score and total NIH-CPSI score increased as anxiety symptoms worsened. After drug treatment, pain and urination symptoms were improved in the non-anxiety group, but the quality of life score and total NIH-CPSI score did not change significantly. After psychological intervention, the anxiety group had lower total NIH-CPSI score and other scores. 【Conclusion】 It is not uncommon for CP/CPPS patients to have a comorbidity of anxiety. The increase in the total NIH-CPSI score is caused by the increase of pain score and decrease of quality of life score. Active psychological intervention can improve anxiety, urinary symptoms, pain symptoms and quality of life.
