This paper summarized the experience of fire needling combined with black cloth ointment in the treatment of keloid. In terms of the pathogenesis of keloid， it is believed that "phlegm causes stasis， and then stasis accumulates into tumors" is the key； the internal obstruction of phlegm and stasis caused by insufficient endowment and invasion of external pathogens is the root of the disease， while the endogenous generation of phlegm and dampness is the branch. It is therefore proposed to explore the etiology and pathogenesis of keloid from the perspective of "phlegm-stasis-tumor"， and the treatment principle is mainly to eliminate phlegm， dispel stasis and dissolve tumors， supplemented with heat-clearing and toxin-resolving. Treatment methods include oral administration of Chinese herbal medicinals and external treatment. Self-made formula for keloid is taken orally， with the main functions of dissolving phlegm， dispelling stasis and clearing heat， to finally dissolve the tumors. For external treatment， fire needling is used to pierce the skin and to open the striae and interstices， and force out the toxin pathogens such as phlegm-heat and stasis-heat with fire power， thereby clearing heat， dissolving phlegm， dispelling stasis and resolving toxins. Black cloth ointment can be used to the affected area to unblock meridians and collaterals， clear heat-toxin and dissolve phlegm-stasis， thereby softening hardness and dissipating masses.

Objective To observe the value of ultrasound-guided intra-articular injection of hypertonic glucose(HG)for treating knee osteoarthritis in plateau area.Methods Ninety-one patients with knee osteoarthritis in plateau area(124 affected knee joints)were enrolled.The knee joints were divided into 20％HG group(n=67),25％HG group(n=42)or sodium hyaluronate group(n=15)based on the medication.Clinical and ultrasound scores were compared before and after treatment,and the efficacy of injection of HG was evaluated.Results At the 12th and 48th weeks after treatment,visual analog scale(VAS)scores decreased in all 3 groups(all P＜0.05),and Lysholm scores of 20％HG group and 25％HG group increased compared to those before treatment(all P＜0.05).The difference of Lysholm score before and in the 12th week after treatment,and of VAS score before and in the 48th week after treatment of 25％HG group were higher than those of 20％HG group(both P＜0.05).The joint exudation score of 20％HG group decreased in the 48th week after treatment compared to that before treatment(P＜0.05),and the synovial blood flow score decreased in the 12th and 48th weeks after treatment compared to those before treatment(both P＜0.05).The joint exudation score of 25％HG group decreased in the 48th week after treatment compared to that before treatment(P＜0.05),and the synovial hyperplasia and synovial blood flow score decreased in the 12th and 48th weeks after treatment compared to before treatment(all P＜0.05).The joint exudation score of sodium hyaluronate group decreased in the 48th week after treatment compared to that before treatment(P＜0.05),and the synovial hyperplasia score decreased in the 12th and 48th weeks after treatment compared to that before treatment(both P＜0.05).Conclusion Ultrasound-guided intra-articular injection of HG,esp.25％HG,had certain value for treating knee osteoarthritis in plateau area.

Objective:To explore the effects of repeated transcranial magnetic stimulation(rTMS)at different stimulating sessions on upper limb motor function and brain functional connectivity in stroke patients,targeting on stimu-late the contralateral premotor cortex(PMC). Method:Sixty patients with upper limb motor dysfunction after ischemic stroke were randomly assigned to 6-week rTMS group,4-week rTMS group,2-week rTMS group or control group,each with 15 participants.Up-per limb Brunnstrom stage,Fugl-Meyer assessment for upper extremity(FMA-UE)and Wolf motor function test(WMFT)were assessed before and after treatment to evaluate behavioral outcomes.The functional connec-tivity was analyzed by resting state functional magnetic resonance imaging(rs-fMRI)with the contralateral PMC as the seed point. Result:After treatment,the FMA-UE and WMFT scores of the 2-week rTMS group were significantly differ-ent from those of the 4-week and 6-week rTMS groups(P＜0.05),but there was no significant difference be-tween the 4-week rTMS group and the 6-week rTMS group(P＞0.05).Functional connectivity analysis using contralateral PMC as a seed point showed that functional connections were enhanced between contralateral PMC and ipsilateral anterior central gyrus,as well as the contralateral middle temporal gyrus and precuneus af-ter rTMS treatment(P＜0.05). Conclusion:The 4-week rTMS group has the best duration-benefit compared with the 2-week rTMS group and the 6-week rTMS group.The probable mechanism was related to that rTMS treatment could reduce the ef-fect of interhemispheric inhibition on motor cortex,and then enhance the cortico-cortical functional connectivi-ty in the contralateral hemisphere effectively,resulting in the recovery of upper limb motor function.

The uPA-uPAR system is highly expressed in various tumor tissues. This system can promote the degradation of extracellular matrix proteins, as well as combine with vitronectin and integrin to transmit intracellular signal transduction. Subsequently, it mediates the occurrence and development of tumors. In recent years, a series of therapeutic programs that target this system has achieved notable results in tumor treatment, and some of them have been under the clinical trial stage, thus providing new ideas for tumor targeted therapy. Therefore, this paper intends to provide a review of research progress on the gene therapy, drug therapy, and immunotherapy targeting uPA-uPAR system.

Objective : To explore the clinical application value of reflectance confocal microscopy(RCM) in the diagnosis of actinic cheilitis(AC). Methods: After approval by the hospital ethics committee and informed consent given by the patients, from October 2020 to July 2022, 17 patients who were diagnosed with actinic cheilitis in the Ninth People's Hospital affiliated with Shanghai Jiao Tong University School of Medicine were retrospectively analyzed. The white keratotic lesions of the lips were scanned with reflectance confocal microscopy, and the image characteristics were summarized and analyzed, including epithelial hyperplasia/atrophy, hyperkeratosis, inflammatory cell infiltration, blood vessel dilatation, solar elastosis, atypical keratinocytes, widening of intercellular spaces, degeneration of basal cell layer, and pigmentation. We used the sample compliance rate to measure the correlation between RCM parameters and histopathological diagnostic criteria for AC and kappa concordance analysis to calculate the concordance between RCM and pathological diagnosis. Results: Under RCM, the sample correct rates for epithelial hyperplasia/atrophy, hyperkeratosis, inflammatory cell infiltration, vasodilation, and solar elastosis were 76.5%, 100%, 100%, 64.7%, and 70.6%, the sample accuracy compared with pathological diagnosis was 82.4%, 47.1%, 94.1%, 88.2% and 76.5%, respectively. We also observed that 100%, 88.2%, 76.5%, and 88.2% of AC patients showed RCM features of atypical keratinocytes, widening of intercellular spaces, degeneration of the basal cell layer, and pigmentation, respectively. The kappa value of hyperkeratosis and inflammatory cell infiltration was 1. The kappa value of blood vessel dilatation was 0.645. Conclusion Reflectance confocal microscopy is noninvasive and versatile and has clinical application value in the diagnosis of actinic cheilitis.
