Objective]To compare therapeutic effects of acupuncture combined with oral administration of Chinese medicine treatment of chronic nonspecific ulcerative colitis and simple oral administration of herbal medicine. [Methods] 102 cases of chronic nonspecific ulcerative colitis patients were randomly divided into the treatment group and the control group for oral Chinese medicine. 52 cases in the treatment group, acupuncture combined with traditional Chinese medicine treatment; internal medicine and 50 cases in the control group, the simple use of Chinese herbal medicine. [Results]The treatment group total effectiveness was 98.1%, oral Chinese medicine control group total effectiveness 86%, two groups had significant difference( P<0.05). After 1 year of follow-up, 3 cases of recurrent oral Chinese medicine treatment group, the control group recurred in 9 cases, there was significant difference between two groups(P<0.05). The curative effect of treatment group was higher than that of oral administration of Chinese medicine control group. [Conclusion]The treatment of chronic nonspecific ulcerative colitis other than purely internal medicine therapy has better acupuncture combined with traditional Chinese medicine.

Objective To evaluate the influence of the single and multiple intervertebral space radiofrequency ablation nucleoplasty on the sheep cervical spine stability.Methods Twenty healthy adult sheep were randomly divided into single intervertebral space operation group (A group )and multiple intervertebral space operation group ( B group ),each group was subdivided into postoperative 24 hours group ( A1,B1 group ) and post- operative 3 months group ( A2,B2 group),each group had five sheep.Radiofrequency ablation nucleoplasty on sheep C3/4 in the single intervertebral space operation group or C3/4,C4/5 in multiple intervertebral space operation group.Preoperative cervical vertebrae roentgenograms from all samples in neutral,lateral,hyperextension and hyperflexion positions were collected,and 5F pipe was used as the survey mark of ieonography.For the postoperative 24 hours group( A1,B1 group ),the roentgenograms were collected postoperatively 24 hours later,while for post- operative 3 months group (A2,B2 group),they were collected postoperatively 3 months later.The height of operative intervertebral space,horizontal and angular displacement of neighboring vertebral body were measured respectively.Results The roentgenograms showed no any obvious decrease in the height of intervertebral disc and no any increase in horizontal and angular displacement of neighboring vertebral body were observed in single intervertebral space operation group (A group) and multiple intervertebral space operation group (B group ).There was no significant difference between pre - operation and post - operation in them ( P ＞ 0.05 ).Conclusions The stability of the sheep cervical spine had not been affected by the single or multiple intervertebral space radiofrequency ablation nucleoplasty on the basis of X-ray results.The radiofrequency ablation nucleoplasty had no influences on the stability of sheep cervical vertebrae.

Objective Antineutrophil cytoplasmic antibody (ANCA) associated vasculitis(AAV)is a systemic necrotizing small-vessel vasculitis, and myeloperoxidase(MPO) is one of the main antigens that ANCA can recognize.This study was to investigate the clinical significance of MPO, activated complement C5a fragment and ceruloplasmin ( Cp) in the peripheral blood of patients with MPO-ANCA associated vasculitis ( MPO-AAV) in active phase by observing their changes. Methods 132 MPO-AAV patients at active stage were selected as the patient group, while the control group was made up of 30 healthy controls.Peri-nuclear ANCA (p-ANCA) and MPO-ANCA in the patient group were detected by IIF and ELISA, respectively.The levels of MPO, Cp and C5a in both groups were tested by ELISA.The Birmingham vasculitis activity score (BVAS) of every patient was calculated.In the patient group, the relationship among MPO, Cp, C5a and MPO-ANCA were analysed, and the association between BVAS and each of them was also explored. Results The levels of MPO, CP, C5a in the patient group were significantly higher than those in the health control group [MPO:400.7(333.5~506.1) vs 286.9(225.5~329.1)IU/L, P<0.001;C5a:336.7 (277.6~403.5) vs 236.8 (204.2~304.1) ng/mL, P<0.001;Cp:481.1 (387.9~535.9) vs 326.9 (177.1~405.5) ng/mL,P<0.001].The associations between MPO and Cp, C5a and MPO, C5a and Cp in the patient group were statistically significant ( r=0.663, P<0.001;r=0.792, P<0.001;r=0.637, P<0.001, respectively).No significant correlation was found in MPO-ANCA and any of these indexes.MPO-ANCA had a positive association with the total BVAS, the kidney BVAS, and the lung BVAS ( r=0.247, P=0.004;r=0.339,P<0.001 and r=0.191, P=0.028, respec-tively) .p-ANCA had a positive correlation with the kidney BVAS ( r=0.208, P=0.017) while C5a had a negative correlation with the kidney BVAS ( r=-0.207, P=0.018) . Conclusion The levels of MPO, Cp and C5a increased significantly in the peripheral blood of MPO-AAV patients in active phase.The complex interactions among MPO, Cp, C5a and ANCA might influence the clinical damage in MPO-AAV.Notablely, the influence from MPO-ANCA might be most obvious while C5a might affect renal damage more markedly.

Patellofemoral osteoarthritis (PFOA) is a subtype of knee osteoarthritis that has gained popularity in recent years due to its high prevalence and disease burden. The National Clinical Research Center for Geriatric Disorders (Xiangya Hospital) and the Joint Surgery Branch of the Chinese Orthopaedic Association, together with the editorial department of the Chinese Journal of Orthopaedics, convened a panel of orthopaedic experts to come up with guidelines. Subsequently, the Chinese clinical practice guideline for patellofemoral osteoarthritis (2020 edition) was officially released in September 2020. This is of utmost importance in standardizing the clinical diagnosis and treatment of PFOA in China. The present guideline focused on the diagnosis (symptoms, signs and imaging changes), non-surgical interventions (primary treatment and pharmacotherapy) and surgical interventions (repair and reconstruction) of PFOA. The present interpretation aims to address key emerging clinical issues in the diagnosis and treatment of PFOA in China.
