Rosacea is a psychosomatic disorder characterized by a distinct neurobiological etiology. It is prone to be comorbid with many neuropsychiatric conditions, and imposes a significant psychosocial burden. This article discusses the psychosomatic attributes of rosacea from neurological, psychiatric, social, and psychological perspectives, aiming to enhance dermatologists′ understanding of its psychosomatic nature.

Objective:To explorethe effect of acceptance and commitment therapy on self-disclosure, coping style and post-traumatic growth in patients with ovarian cancer undergoing chemotherapy after surgery.Methods:A total of 84 patients with ovarian cancer undergoing chemotherapy after surgery were recruited from the gynecology ward of the First Affiliated Hospital of University of Science and Technology of China for randomized controlled trial, from February 2022 to October 2022. All participants were divided into the intervention group and the control group with 42 patients in each group by random number table method. The patients in control group received routine care. The intervention group was given acceptance and commitment therapy (ACT) on the basis of the control group and intervened for three cycles of chemotherapy. The scores of Distress Disclosure Index (DDI), Cancer Coping Modes Questionnaire (CCMQ), and Post-Traumatic Growth Inventory (PTGI) were compared between the two groups before and after intervention.Results:There was no significant difference in the scores of DDI, CCMQ and PTGI between the two groups before intervention ( P>0.05). After intervention, DDI scorein intervention group was (38.81 ± 5.96) points, significantly higher than that in control group (34.43 ± 4.79) points, the difference was statistically significant ( t = 3.71, P<0.01). In terms of coping styles, after intervention, the scores of five dimensions of fantasy, resignation, avoidance, catharsis and confrontation were 6.00(6.00, 8.00), 9.00(8.00, 12.00), 9.00(8.75, 11.00), 7.00(6.00, 8.00) and 20.00(16.00, 21.00) points in the invention group, compared with the control group of 8.00(7.75, 9.00), 11.00(9.75, 13.00), 11.00(9.00, 13.00), 9.00(8.00, 12.00) and 16.00(13.00, 18.50) points, the differences were statistically significant ( Z = 2.86 to 5.11, all P<0.01). The total PTGI score in intervention group was (71.43 ± 8.68) points, significantly higher than that in control group(63.98 ± 6.92) points, the difference was statistically significant ( t = 4.35, P<0.01). Conclusions:ACT can increase self-disclosure, enhance positive coping, and promote post-traumatic growth in ovarian cancer patientsundergoing chemotherapy after surgery.

Objective:To detect gene mutations in 1 patient with Vohwinkel syndrome who presented with palmoplantar keratoderma, pseudo-ainhum and deafness.Methods:Clinical data were collected from the proband, and a genetic test was performed to identify mutation sites.Results:Clinical manifestations of the proband were consistent with classical Vohwinkel syndrome. The genetic test revealed a heterozygous mutation c.160A>C (p.N54H) in the GJB2 gene, which was not detected in her parents or healthy controls.Conclusion:The heterozygous mutation c.160A>C (p.N54H) in the GJB2 gene was first identified in a patient with classical Vohwinkel syndrome, and there were overlaps in mutation sites between classical Vohwinkel syndrome and palmoplantar keratoderma with deafness.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

Objective:To investigate the consistency of indirect calorimetry, Harris-Benedict (H-B) formula method and rule of thumb in calculating the daily total energy expenditure (TDEE) of patients with acute pancreatitis (AP), and provide the basis for the formulation of reasonable nutritional support program.Methods:A total of 66 AP patients admitted to Henan Provincial People's Hospital from June 2020 to December 2020 were included and retrospectively analyzed, including 35 males and 31 females with an average age of 41.8 years. They were divided into mild acute pancreatitis (MAP) group ( n=20) and moderate to severe AP group ( n=46) according to severity. TDEE was calculated by indirect calorimetry, H-B formula and rule of thumb, and Pearson correlation analysis and Bland-Altman diagram were used to analyze the correlation and consistency of the three methods, respectively. Results:There were no statistical significances in the TDEE of MAP group calculated by indirect calorimetry, H-B formula method and rule of thumb (both P>0.05). TDEE calculated by indirect calorimetry were higher than that of calculated by H-B formula and thumb method both in moderate and severe AP groups, and the difference was statistically significant (both P<0.05). Pearson correlation analysis showed that H-B formula method was positively correlated with the TDEE calculated by indirect calorimetry, and the correlation was 0.61 ( P<0.05). Bland-Altman plot analysis showed the consistence of the two methods. TDEE calculated by rule of thumb was positively correlated with that calculated by indirect calorimetry, and the correlation was 0.75 ( P<0.05). The bland-Altman plot analysis showed a good consistency between the two methods. Conclusion:For MAP patients, TDEE can be calculated by the H-B formula method and rule of thumb. In moderate and severe AP patients, TDEE should be calculated by indirect calorimetry as the basis for the formulation of nutritional support plan.

Objective:To measure the coagulation function of patients with adenomyosis so as to explore its relationship with increased menstrual amount and its clinical significance.Methods:From January 2014 to May 2019, clinical data of patients with hysterectomy in which 111 pathologically diagnosed adenomyosis (case group) and 115 with uterine myoma (control group) in Peking University First Hospital were retrospectively analyzed. The changes in coagulation function of the two groups were compared, and the correlation between coagulation and uterine volume in the adenomyosis group was analyzed.Results:(1) The activated partial thromboplastin time (APTT) was longer in the adenomyosis group than that in the uterine myoma group [(30.4±3.1), (29.6±2.5) s, respectively; P<0.05], while the thrombin time (TT) was shorter than that in the control group [(14.2±1.2), (14.6±1.0) s, respectively; P<0.05]. (2) According to the results of the Pearson correlation test, there was a positive correlation between prothrombin time (PT; r=0.135, P=0.042) and fibrinogen (FIB-C; r=0.139, P=0.036). (3) Platelet counts were higher in the anemia group of adenomyosis than that in the non-anemia group [(323±79)×10 9/L, (274±56)×10 9/L, respectively; P<0.05]. (4) FIB-C in non-anemia group of adenomyosis was lower than non-anemia group of uterine myoma [(2.8±0.5), (3.0±0.6) g/L, respectively; P<0.05], the anemia group of adenomyosis shortened TT compared with the anemia group of uterine myoma [(14.4±1.2), (15.2±0.9) s, respectively; P<0.05]. Conclusion:Patients with adenomyosis have abnormal coagulation function, which may be related to the increase amount of menstruation, and anemia may also be involved in coagulation disorders.

Objective: To explore the clinical features and prognosis in patients with Takayasu arteritis (TA) combining neurological symptoms. Methods: We retrospectively studied 274 TA patients combining neurological symptoms who admitted to our hospital from 2002-01 to 2013-10 for their clinical and imaging features with prognosis. Results: The ratio of male to female was 1:4.3 and the mean age of disease onset was at (28.2±11.2) years. The most common neurological symptom was dizziness (214/274 cases, 78.1%), most frequent type was type III TA (112 cases, 40.9%), most common affected artery was left subclavian artery (147 cases, 53.6%), and there were 77 cases (28.1%) with (3-4) branches of the aortic arch involvement. For stroke conditions, ischemic stroke was more frequently observed in patients with steno-occlusive lesions in subclavian artery and common carotid artery, while hemorrhagic stroke was more frequently found in patients with steno-occlusive lesions in descending aorta, abdominal aorta and/or renal artery. Heart failure was the most common cause of death, it was also the most common cardiovascular event in surviving cohorts. Conclusion: TA patients could have many neurological symptoms, which were related to the number and site of artery involvement.

Objective To prepare the Fe3O4-1oaded biodegradable liquid-solid phase inversion poly(lactic-co-glycolic acid) (PLGA) in situ implant for ultrasound-guided injection into nude mouse tumor model,and to investigate its clinical effect in thermomagnetic treatment of nude mice with human liver cancer SMMC-7721 cells in an alternating magnetic field.Methods An in situ implant containing 10％ Fe3O4 was prepared,and 50 μtl Fe3O4-PLGA-NMP gel was injected into the subcutaneous tissue of Kunming mice.The degradation of this material was observed for 2 consecutive months,and the changes in body weight were recorded.HE staining and Prussian blue staining were performed for the heart,liver,spleen,lung,and kidney of Kunming mice.Fresh ex vivo bovine liver was taken and cut into cubes with a dimension of 2 cmu×2 cm×2 cm and then 50 μl Fe3O4-PLGA-NMMP gel was injected;after phase inversion,the cubes ofex vivo bovine liver were heated for 1,2,3,4,and 5 minutes,respectively,and then cut open for observing the range of ablation;HE staining was also performed.Micro-CT scan was performed after ultrasound-guided injection of 50 μl Fe3O4-PLGA gel into the tumors of the nude mice,and then the nude mice were divided into treatment group and control group.The mice in the treatment group were given thermomagnetic treatment for 3 minutes,and tumor growth was observed daily.Results The biodegradation of Fe3O4-PLGA-NMMP implant showed that the subcutaneously injected material was gradually metabolized at 2 weeks after injection and that the nude mice were in good condition.The bovine liver ablation experiment showed that the range of ablation of 50 μl Fe3O4-PLGA implant reached 1.46 ± 0.11 cm.HE staining showed that part of bovine liver had coagulative necrosis.The phase inversion experiment of Fe3O4-PLGA gel showed quick liquid-solid phase inversion of the material after injection into the tumor,and the process of liquid-solid phase inversion could be monitored by ultrasound and CT.The detachment and incrustation of the tumor started at 2 days after treatment,the wound started to heal 15 days later,and the tumor tissue disappeared completely.Conclusion Ultrasound-guided injection of biodegradable Fe3O4-PLGA in situ implant combined with magnetic thermal ablation can effecfively treat human liver cancer SMMC-7721 cells in nude mice.

Objective: To explore a single center large cohort of patients with Takayasu’s arteritis for their clinical manifestation and long-term outcome in China. Methods: We retrospectively analyzed 566 patients with Takayasu’s arteritis admitted in our hospital from 2002-01 to 2013-11 for their clinical characteristics, laboratory ifndings, angiographic features, treatment and long-term outcomes. Results: The patient’s ratio for female to male gender was 1 to 3.8 and the average onset age was (28.9 ± 12.0) years. The most common non-speciifc symptom, initial symptom and complication were fever (52/566 patients, 9.2%), dizziness (214 patients, 37.8%) and hypertension (392 patients, 69.3%) respectively. The patients with pulmonary artery and coronary artery involvement were 83 (14.7%) and 66 (11.7%) respectively, and 131 (23.1%) patients had faster erythrocyte sedimentation rate. The major vascular damage was steno-occlusive lesion and the most common involvement was left sub-clavian artery, which was observed in 278 (49.1%) patients. The treatments were mainly included in medication, interventional therapy, autologous blood vessel transplantation, artiifcial blood vessel transplantation and aortic valve replacement. There were 32 patients died during the mean follow-up period of (5.0 ± 0.2) years. Hypertension, complication and the progressive stage of disease were the major factors affecting prognosis in relevant patients (regression coefifcients: 4.664, 1.959 and 1.870 respectively, allP<0.05). Conclusion: Hypertension was the leading reason for patients’ hospital visit. Takayasu’s arteritis was closely related to cardiovascular disease, the early diagnosis and treatment were really important in clinical practice.
