A 67-year-old female patient with erythrodermic psoriasis showed no significant improvement in rash after 2 weeks of treatments with acitretin, ebastine, etc., with the psoriasis area and severity index (PASI) score of 72 points (the highest value). Secukinumab 300 mg once a week was given by subcutaneous injection, which was changed to 300 mg once a month after 5 weeks of medication. After 5 weeks of treatment(medication 5 times), the patient′s PASI improvement rate was 75%, but the patient developed alopecia areata and her eyebrows fall off. After 6 months of treatment, the PASI improvement rate was 100%, but the patient developed alopecia totalis and her eyebrows completely disappeared. During the 9-month follow-up, the patient did not stop taking medication or received hair loss treatment. No psoriasis rash recurred and her hair loss was not improved.

Objective:To evaluate the application effect of management mode based on constraint theory for medical equipment in equipment management of vascular surgery. Methods:Based on five-step method of constraint theory,an operation evaluation system was formulated. An information management mode of medical equipment was constructed to manage quality of medical equipment in department of vascular surgery. A total of 60 sets used medical equipment in the Department of Vascular Surgery at The Second Affiliated Hospital of Xi'an Jiaotong University from 2021 to 2022 were selected. The conventional management mode was adopted to manage these equipment between January to December 2021,while equipment was managed by using medical equipment management mode based on constraint theory (constraint theory management) of the department of vascular surgery from January to December 2022. The quality scores of operation and maintenance of equipment,average incidence rates of risk,configuration effectiveness,and timeliness of equipment management were compared between the two management modes. Results:After constraint theory management was implemented,the average scores of operation and maintenance of equipment,which included success starting-up,operation,routine maintenance and fault repair,were respectively (90.69±8.65),(89.65±4.65),(88.65±5.63),and (90.58±6.01),all of which were higher than those of conventional management mode. The differences of them between two modes were statistically significant (t=13.482,17.867,14.552,14.449,P<0.05). The average incidence rates of the risks of testing equipment,treatment,monitoring equipment and auxiliary equipment of adopting constraint theory mode management were (0.89±0.22)％,(0.84±0.23)％,(0.74±0.32)％ and (0.75±0.32％),all which were lower than those of the conventional management mode,with statistically significant differences (t=9.162,17.745,19.469,15.019,P<0.05). The average utilization rate of equipment and the average amplification of cost benefit of equipment were respectively (88.69±5.54)％ and (50.36±2.69)％ after constraint theory mode was adopted,which were significantly higher than those of conventional management mode,and the average floating rate of using equipment of constraint theory mode was (1.23±0.97)％,which was lower than that of conventional management model,the differences of them between two modes were statistically significant (t=14.174,21.564,11.811,P<0.05). The average times of emergency management for risk events included the safety of power consumption of equipment,safety of diagnosis and treatment,biological safety and radiation safety were respectively (2.36±0.64)h,(3.26±0.78)h,(4.23±1.24)h and (2.26±1.23)h after the constraint theory mode was adopted,all of which were significantly less than those of conventional management mode,and the differences of them between two modes were statistically significant (t=16.704,13.421,9.029,13.971,P<0.05). Conclusion:The application of the management mode based on the constraint theory of medical equipment in department of vascular surgery can improve the quality of operation and maintenance of equipment for safety,and shorten the emergency response time of equipment,and reduce the incidence of equipment risk,and strengthen the effect of configuration for equipment.

BACKGROUND:Kinesio taping is often used for the treatment of various sports injuries.The methods of foot and ankle sports taping are complex and diverse.Among them,Fascia taping is applicable to a wider range of people and can be used for different foot posture types,but it still lacks of practical verification,and its specific biomechanical role is not clear. OBJECTIVE:To observe the changes in plantar pressure characteristics of subjects with different foot positions during walking and jogging after Fascia taping. METHODS:Thirty-seven young healthy subjects were recruited from the Yantai campus of Binzhou Medical University to conduct the test.They were scored according to the foot posture index-six items version,and were divided into the supination foot group,the neutral foot group,and the pronation foot group.The static foot morphological indexes(including navicular drop,arch height index,arch height flexibility-longitudinal arch,and arch height flexibility-transverse arch)and the pressure-time integral of each foot zone during walking and jogging were collected and calculated respectively before and after Kinesio taping.The specific biomechanical mechanism of Fascia taping was analyzed. RESULTS AND CONCLUSION:(1)General data:There was no statistical difference among the three groups of subjects in general data,such as gender,height,and body mass index(P>0.05).Before taping,there was a significant difference in the foot morphological indexes and the areas of the outer front foot,midfoot,and hindfoot between different foot posture groups(P<0.01).(2)Static foot morphological indexes:After taping,there was no statistically significant difference between the groups in navicular drop,arch height flexibility-longitudinal arch,and arch height flexibility-transverse arch(P>0.05),while there was still a significant difference between the groups in the arch height index(P<0.05).In the supination foot group,the arch height index increased slightly,but there was no significant difference before and after taping(P>0.05).In the pronation foot group,the navicular drop and arch height flexibility-longitudinal arch was significantly reduced,and the arch height index was increased.There was a significant difference before and after taping(P<0.05).(3)The index of plantar pressure during walking:After taping,there was no significant difference between the three groups in the area of lateral forefoot and medial midfoot(P>0.05).In the pronation foot group,the lateral load of the forefoot increased after taping(P<0.05).In the supination position group,the load of the lateral forefoot and midfoot regions increased significantly(P<0.05),while the difference in the rear foot region was not significant(P>0.05).(4)The index of plantar pressure during jogging:After taping,there was no statistically significant difference between groups in the lateral forefoot(P>0.05).In the pronation foot group,the load of the medial forefoot increased significantly(P<0.05).In the supination position group,the load of the lateral forefoot,the middle foot and the rear foot region increased significantly(P<0.05).(5)The results showed that the Fascia taping was suitable for different foot postures.It could not only correct the static foot structure of subjects with different foot postures,but also regulate the abnormal plantar pressure distribution during the dynamic activities of walking and jogging,and the load of the midfoot,forefoot,and hindfoot in the supination and pronation posture tended to normal foot posture load level.

Objective:To explore the clinical efficacy of Kinesio taping combined with extracorporeal shock wave and the plantar pressure evaluation in the treatment of plantar fasciitis. Method:A total of 67 patients with unilateral plantar fasciitis were randomly divided into the control group(ESWT group)and the experimental group(KT combined group).The patients in the two groups were given the same health education and extracorporeal shock wave treatment(ESWT),and the experimental group was treated with Kinesio taping(KT).The pain and functional activity were evaluated by pain visual analogue scale and AOFAS ankle and hind-foot function scale;The insole plantar pressure measuring system was used to mea-sure the peak pressure values of each plantar regions.The clinical efficacy and plantar pressure of the affected side were compared before treatment,the 3rd week of treatment and 5th week of treatment. Result:There was no significant difference in various indcators of the measurements between the two groups before treatment(P＞0.05).The score of pain rating,functional activity scale score and plantar pressure of pa-tients in both groups were significantly improved at the 3rd week and the 5th week of treatment(P＜0.05),com-pared with those before treatment.At the 3rd week of treatment,there was no significant difference between the two groups in pain degree and functional activity scale score(P＞0.05),but there was statistical difference in plantar pressure analysis(P＜0.05).The peak force weight ratio of the medial heel in the KT combined group was significantly greater than that in the control group.At the 5th week of treatment,there were statisti-cally significant differences between the two groups in the score of pain rating,functional activity scale score and plantar pressure(P＜0.05).The KT combined treatment group was significantly better than the control group in the pain improvement and functional activity,and the weight bearing of the middle foot and hind foot was also significantly higher than the control group. Conclusion:Compared with the simple extracorporeal shock wave therapy,the combination of KT therapy can better relieve pain,improve the function of hind foot,correct abnormal foot weight bearing,and improve the gait of patients.

ObjectiveTo explore the effect of core stability training on dynamic balance and surface electromyography (sEMG) after anterior cruciate ligament reconstruction (ACLR), and to analyze the correlation between balance index and sEMG. MethodsFrom March to December, 2022, 32 patients with ACLR in Yantai Affiliated Hospital of Binzhou Medical University were randomly divided into control group (n = 16) and experimental group (n = 16). The control group accepted routine rehabilitation treatment, and the experimental group added core stability training, for six weeks. They were evaluated with American Hospital for Special Surgery Knee Score (HSS) and International Knee Documentation Committee Knee Score (IKDC), and the dynamic balance function and sEMG were measured before and after treatment, and the correlation between dynamic balance index and root mean square (RMS) of sEMG was analyzed. ResultsAfter treatment, the scores of HSS and IKDC increased significantly in both groups (|Z| > 3.526, |t| > 63.544, P < 0.001), and were better in the experimental group than in the control group (Z = -2.392, t = 2.650, P < 0.05); the length of gait line and single support line increased significantly, the medial-lateral displacement displacement decreased (|t| > 2.368, Z = -3.516, P < 0.05), and they were better in the experimental group than in the control group (|t| > 2.497, Z = -3.091, P < 0.05); the RMS of gluteus maximus and gluteus medius increased in the experimental group (t = -5.900, Z = -2.741, P < 0.01), and were better than those in the control group (t = 3.930, Z = -3.260, P < 0.01). After treatment, the RMS of gluteus maximus and gluteus medius in both groups were positively correlated with gait line length and single support line length, and were negatively correlated with medial-lateral displacement (|r| > 0.502, P < 0.01). ConclusionCore stability training could significantly improve knee joint function and dynamic balance, and enhance the activation of gluteus maximus and gluteus medius. Dynamic balance is highly correlated with sEMG.

Paradoxical reactions related to biological agents refers to the contradictory phenomenon that occurs during the treatment of biological agents, which is contrary to the treatment purpose or exacerbates the condition of the treated disease. The first biological agent reported to trigger paradoxical reactions is TNF-α inhibitors, which appeared firstly in the treatment of patients with rheumatic diseases, followed by psoriasis and inflammatory bowel diseases. Other types of biological agents such as interleukin (IL) 12/23 inhibitor ustekinumab and IL-17 inhibitors secukinumab and ixekizumab can also cause paradoxical reactions. The mechanism of paradoxical reactions related to biological agents in the treatment of psoriasis, the occurrence and clinical manifestations of common paradoxical reactions (paradoxical psoriasis, arthritis, inflammatory bowel disease, hidradenitis suppurativa, etc.), and the management principles of paradoxical reactions related to biological agents in the treatment of psoriasis are reviewed in this article.
