Objective:To explore and analyze the clinical features of patients with immunoglobulin (Ig)G4-related hepatobiliary-pancreatic disease and the independent factors affecting the prognosis of IgG4-related sclerosing cholangitis (IgG4-SC).Methods:The clinical data of 179 adult cases diagnosed with IgG4-related hepato-pancreato-biliary disease in the Division of Gastroenterology and Hepatology, Renji Hospital, Shanghai Jiao Tong University School of Medicine from January 2011 to December 2022 were retrospectively analyzed. Patients were divided into three groups: isolated IgG4-SC, IgG4-SC/type 1 autoimmune pancreatitis(type 1 AIP), and isolated AIP according to the clinical manifestations. Demographic characteristics, baseline biochemical immunological indexes, and imaging manifestations were analyzed. The treatment response rate and survival rate were compared. The COX proportional hazards model was used to analyze the independent factors related to prognosis.Results:The mean age of diagnosis of patients with IgG4-related hepatobiliary-pancreatic disease was 60.3±12.0 years. Males accounted for 74.9%, and the median follow-up time was 38 months. The 1-year clinical response rate of patients with isolated IgG4-SC was lower than that of IgG4-SC/AIP (67.9% vs. 91.7%, P=0.019), and the primary endpoint-free 5-year survival rate was significantly reduced (64.9% vs. 95.9%, P<0.001). COX regression analysis showed that having cirrhosis before treatment ( HR=6.708, P=0.004) and poor response after half a year of treatment ( HR=11.488, P=0.002) were independent risk factors associated with the occurrence of adverse events in hepatobiliary diseases among patients with IgG4-SC. Conclusions:The clinical response rate and survival rate of patients with isolated IgG4-SC are lower than those of patients with IgG4-SC/AIP. Patients with IgG4-SC who do not respond well at six months of treatment and who have progressed to cirrhosis before treatment are at significantly increased risk of adverse events.

In line with the significant changes in disease spectrum, the wound healing discipline in China has shown a good momentum of development from budding to rapid growth. At present, improving the connotation of disciplinary development determines the speed and quality of disciplinary development in the future. The characteristics of wound diseases determine that the wound healing discipline must have the following property: standardization, integration, and translation. Here is the initial introduction on the connotation of standardization, collaboration, and translation in clinical practice of wound healing discipline. Besides, the discussions on standardization, integration, and translation in the 13 th National Conference of Wound Repair (Healing) and Tissue Regeneration were summarized. It is expected that these achievements can be reflected and improved in the construction of the wound healing discipline in China.

Objective:To understand the current situation of nurses in 52 hospitals in China on mastery of knowledge about skin injury in the elderly based on the background of mixed-mode homogenization training.Methods:Using the convenient sampling method, a total of 1 067 nurses from 52 hospitals in China were selected as the research objects in January 2021. A self-designed questionnaire on knowledge of skin injury in the elderly was used to investigate the nurses through the questionnaire star and univariate analysis was used to analyze the influencing factors. A total of 1 067 questionnaires were distributed and 1 067 valid questionnaires were recovered, and the effective recovery rate was 100%.Results:The knowledge scores of pressure injury, incontinence-associated dermatitis, skin tear and xerosis cutis among 1067 nurses were (95.66±7.37) , (95.65±9.15) , (91.37±15.45) and (87.67±15.91) , respectively. The results of univariate analysis showed that hospital grade was the influencing factor of nurses' knowledge score of pressure injury, skin tear and incontinence-associated dermatitis ( P<0.05) , educational background was the influencing factor of nurses' knowledge score of skin tear ( P<0.05) , professional title was the influencing factor of nurses' knowledge scores of pressure injury, incontinence-associated dermatitis and xerosis cutis ( P<0.05) . Conclusions:Hospitals at all levels need to strengthen the theoretical and practical knowledge training for nurses on skin xerosis and skin tear in the elderly, especially for nurses with primary titles and lower education in grassroots hospitals.

Objective:To explore the status and influencing factors of incontinence-associated dermatitis among elderly inpatients in 52 hospitals nationwide, and to analyze the nursing of elderly inpatients with incontinence, so as to provide a reference for clinical intervention.Methods:On March 31, 2021, convenience sampling was used to select 14 675 elderly inpatients from 52 hospitals across the country as the research object. The self-designed Incontinence-associated Dermatitis Questionnaire for Elderly Inpatients was used to collect general demographic data, health status, incontinence, and skin nursing. Binomial Logistic regression was used to investigate the influencing factors of incontinence-associated dermatitis in elderly inpatients.Results:Among 14 675 elderly inpatients, the prevalence rates of xerosis cutis, incontinence and incontinence-associated dermatitis were 38.78% (5 691/14 675) , 11.06% (1 623/14 675) and 1.91% (280/14 675) , respectively. The prevalence of mild, moderate and severe incontinence-associated dermatitis were 1.27% (186/14 675) , 0.55% (81/14 675) , and 0.09% (13/14 675) , respectively. Among the nursing of 1 623 elderly inpatients with incontinence, the items with low implementation rate were the use neutral lotion to clean skin (14.17%, 230/1 623) , use of skin protectant after moisturizing (17.68%, 287/1 623) , moisturizing after cleansing the skin (28.90%, 469/1 623) . The results of binomial Logistic regression analysis showed that xeroderma, fecal incontinence, urinary and fecal incontinence, ≥2 kinds of combined medication, and hospital stay >30 days were risk factors for incontinence-associated dermatitis in elderly inpatients.Conclusions:The risk factors of incontinence-associated dermatitis in elderly inpatients mainly include xerosis cutis, type of incontinence, ≥2 kinds of combined medication, and hospital stay >30 days.

Objective:To analyze characteristics, related factors and prevention status of moist-associated skin damage of medical staff caused by the second and third levels of personal protection equipment, and provide basis for formulating prevention and treatment countermeasures.Methods:From February 8 to 22, 2020, the convenient sampling method was adopted to select 1 814 medical staff from 161 hospitals in China as the research objects.The questionnaire was uploaded to Questionnaire Star website, and the questionnaire link was sent to the WeChat working group of medical staff. Medical staff voluntarily used mobile phones to fill in and submit demographic data, moist-associated skin damage data, preventive measures data and other data online.Data were exported from the website and the database was established after double check. SPSS software was used to analyze the occurrence characteristics, related factors and prevention status of moist-associated skin damage and put forward countermeasures.Results:A total of 1 761 medical staff from 161 hospitals in China submitted the questionnaire, including 290 males (16.47%) and 1 471 females (83.53%) .The overall prevalence rate of moisture-related skin damage was 18.85% (332/1 761) . The prevalence rate of third-level personal protective equipment was higher than that of second-level personal protective equipment, and the difference was statistically significant ( P=0.001) .The incidence of wearing time greater than 4 hours group was higher than that of less than or equal to 4 hours group, and the difference was statistically significant ( P<0.05) .The prevalence rate of multiple sites was higher than that of single site ( P< 0.001) . Binary Logistic regression analysis showed that the main associated factors that increased the risk were sweating and dampness ( OR=168.52, P<0.001) and wearing third-level personal protective equipment ( OR=1.65, P<0.05) , and only 12.72% (224/1 761) of them took preventive measures before damage. Conclusions:The incidence of moist-associated skin damage of medical staff caused by the second and third levels of personal protective equipment is relatively high. Among them, sweating and wetness and the third level equipment are the main risk factors, and the prevention is insufficient. It is necessary to strengthen assessment, cleansing, moisturizing, skin care, moisture absorption and other preventive strategies. After damage, local anti-inflammatory and protective treatments should be done on the basis of prevention.

Objective:To investigate the status and influencing factors of skin cleaning outside wound (hereinafter referred to as skin) in adult trauma patients.Methods:A multicenter cross-sectional investigation was conducted. From September 1 to 30, 2020, a total of 952 adult trauma patients who met the inclusion criteria were admitted to wound care clinics or trauma surgery wards of 13 military or local Grade Ⅲ Level A hospitals, including the General Hospital of the Eastern Theater Command of People's Liberation Army and the Army Medical Center, etc. A self-designed questionnaire on cleaning status of skin in trauma patients was released through the "questionnaire star" website to investigate basic information such as gender, age, education level, living status, and self-care ability, trauma information such as cause of injury, wound duration, trauma site, trauma depth, wound pain, wound peculiar smell, and wound cleaning solution, and skin cleaning status after injury such as whether to clean or not, cleaning method, cleaning frequency, cleaning duration in each time, or reasons for not cleaning. The patients who cleaned skin regularly after injury were included in cleaning group, and the other patients were included in no cleaning group. The basic information, trauma information, and skin cleaning status after injury of patients in 2 groups were investigated. Data were statistically analyzed with chi-square test, and binary multivariate logistic regression analysis was performed on indicators with statistically significant differences between the two groups to screen the independent influencing factors of skin cleaning in trauma patients.Results:A total of 952 questionnaires were received, and the recovery rate was 100%. Three invalid questionnaires were eliminated, and 949 valid questionnaires were obtained, with an effective rate of 99.68%. In 949 patients, there were 461 (48.6%) males and 488 (51.4%) females, aged 18-100 (50±18) years. Most patients were less than 60 years old, lived with their families, and could take care of themselves completely. Nearly half of the patients were with junior high school or below education level. The main causes of injury were sharp cutting injury and falling injury, the wound duration was 2-365 days, most of the injured parts were limbs and trunk, the wound depth was mostly full-thickness injury, and most patients had wound-related pain and no peculiar smell and used 5 g/L iodophor to clean the wound. Totally 684 (72.1%) patients cleaned their skin after injury, mainly by scrubbing with warm water, the cleaning frequency was mainly once or twice a week, and the cleaning time was mainly 10 or 15 min for each time. Totally 265 (27.9%) patients didn't clean their skin after injury, and the main causes for not cleaning were following the doctor's advice, followed by worrying about wound infection and loss of self-care ability. There were significantly statistical differences in constituent ratios of education level, self-care ability, cause of injury, wound pain, and wound peculiar smell of patients in 2 groups ( χ2=12.365, 24.519, 22.820, 9.572, 92.342, P<0.01). Education level, self-care ability, cause of injury, wound pain, and wound peculiar smell were potential influencing factors of skin cleaning in patients. Binary multivariate logistic regression analysis showed that self-care ability, wound pain, and wound peculiar smell were independent influencing factors of skin cleaning in patients (odds ratio=1.51, 0.52, 3.72, 95% confidence interval=1.08-2.12, 0.42-0.89, 2.66-5.22, P<0.05 or P<0.01). Conclusions:Self-care ability, wound pain, and wound peculiar smell are independent influencing factors of skin cleaning in adult trauma patients.

Objective:To systematically review the risk factors of delayed healing of venous leg ulcer (VLU) so as to provide a guide for developing the personalized nursing strategies.Methods:The Cochrane Library, PubMed, Web of Science, ScienceDirect, Clinicaltrials.gov, ProQuest and Open Grey was retrieved with the English keywords of "varicose ulcer/venous ulcer, non-healing/delayed healing/poor healing, factor/risk factor/influence factor"; the China Biological Medicine (CBM) , Chinese National Knowledge Infrastructure (CNKI) , WanFang Data and VIP was retrieved with the English keywords of "venous leg ulcer/venous ulcer, delayed healing/refractory, risk factors/influencing factors"; the retrieval time ranged from building database to 1st April 2019. Two researchers independently screened literatures, extracted data and assessed the quality of included literatures. The RevMan 5.3 was used to the meta-analysis.Results:Finally, a total of 11 literatures were included and involved 3 894 subjects, 520 cases lost to follow up, 914 cases in case group and 2 460 in control group. Meta-analysis showed that there were 7 risk factors related to delayed healing of VLU including the ages [ OR=1.02, 95% CI (1.01, 1.03) , P<0.01], range of motion of ankle [ OR=4.77, 95% CI (1.79, 12.73) , P<0.01], size of ulcer [ OR=1.27, 95% CI (1.10, 1.47) , P<0.01], duration of ulcer [ OR=1.08, 95% CI (1.01, 1.16) , P=0.03], history of deep vein thrombosis (DVT) [ OR=2.21, 95% CI (1.06, 4.63) , P=0.03], ankle-brachial index<0.8 [ OR=8.71, 95% CI (4.22, 17.99) , P<0.01]and rheumatoid arthritis [ OR=1.37, 95% CI (1.08, 1.73) , P<0.01]with statistical differences, and factors irrelevant to delayed healing of VLU including the body mass index (BMI) [ OR=0.98, 95% CI (0.83, 1.16) , P=0.82], >50% wound covered with fibrin [ OR=1.88, 95% CI (0.99, 3.57) , P=0.06], diabetes mellitus [ OR=1.10, 95% CI (0.70, 1.75) , P=0.67], history of hip or knee replacement [ OR=1.73, 95% CI (0.50, 6.00) , P=0.39]. Conclusions:Evidence shows that the independent risk factors of delayed healing of VLU include the ages, range of motion of ankle, size of ulcer, duration of ulcer, history of DVT, ankle-brachial index<0.8 and rheumatoid arthritis. Those evidences can help to identify the clinical high-risk population of delayed healing of VLU and provide targeted nursing intervention to reduce the healing time of VLU and improve patients' quality of life.

Objective:To explore the effects of early wet compress with traditional Chinese medicine Ru-Yi-Jin-Huang-San on drug extravasation skin injury.Methods:Totally 21 patients with skin injuries caused by extravasation of different drugs from the First People's Hospital of Lianyungang and General Hospital of Eastern Theater Command between January 2017 and December 2019 were selected by convenient sampling. They received local wet compress with Ru-Yi-Jin-Huang-San according to the redness and swelling area, which was replaced once a day until the pain and swelling were ameliorated and the wound healed. Patients with irreversible tissue necrosis underwent debridement, anti-infection, negative pressure wound treatment or wet therapy according to the principles of wound care until the wound healed. The pain score, redness area, healing time and healing outcome were compared before and after wet compress, between upper and lower limbs, between wet compress within 24 hours and wet compress after 24 hours, and between patients with and without drug extravasation.Results:After wet compress with Ru-Yi-Jin-Huang-San for 2-13 days, the skin injury of 18 patients who received wet compress within 2-24 hours after extravasation healed completely, and the healing time was (6.44±2.99) d; 3 cases formed wounds, which healed after local debridement, anti-infection, wet therapy and negative pressure therapy, with a healing time of 67 (28, 154) d. There were statistically significant difference between the pain score before wet compress and those from day 1 to day 7 after wet compress ( P<0.05) ; there were statistically significant differences between the redness and swelling area before wet compress and those from day 1 to day 5 after wet compress ( P<0.05) ; there was no statistically significant difference in the redness and swelling area between day 6 and day 7 ( P>0.05) . There were no statistically significant differences in the pain score and the redness and swelling area between the upper and lower extremities before wet compress ( P>0.05) . 3 days after wet compress, the pain score of the upper extremities was lower than that of the lower extremities, and the difference was statistically significant ( P<0.05) , but there was no statistically significant difference in the redness and swelling area between the lower extremities and the upper extremities ( P>0.05) . Before wet compress, there was no statistically significant difference in the pain score and the redness and swelling area between the groups with different time of wet compress ( P>0.05) . 3 days after wet compress, the pain score of patients who received wet compress within 24 hours was lower than that of patients who received wet compress after 24 hours ( P>0.05) . The healing time of patients who received wet compress within 24 hours was shorter than that of patients who received wet compress after 24 hours, and the difference between the two groups was statistically significant ( P<0.05) . Before wet compress, there were no significant differences in pain score and the redness and swelling area between the groups with extravasation of different drugs ( P>0.05) . 3 days after wet compress, there were no statistically significant differences in the pain score and the redness and swelling area within the antibiotic extravasation group ( P>0.05) . Conclusions:Early wet compress with Ru-Yi-Jin-Huang-San is safe and effective for drug extravasation skin injury. The sooner the wet compress, the better the effect is.
