OBJECTIVE To investigate and analyze the use of acetaminophen in primary medical institutions of Shaanxi province， and to provide evidence for promoting the standardized and rational use of acetaminophen. METHODS According to the method of cluster stratified random sampling， all prescriptions of acetaminophen issued by primary medical institutions in one district and one county （or two districts） were randomly selected from 10 provincial cities of Shaanxi province from 2020 to 2023； the existing clinical diagnoses were classified by using the International Classification of Diseases （ICD） code， and the drug information of collected prescriptions was analyzed descriptively. SPSS 25.0 software was used for single-factor analysis and Logistic regression analysis to find out the key factors affecting the duration of medication ＞10 d. RESULTS A total of 7 375 valid prescriptions for acetaminophen were collected in this study. The patients who used acetaminophen were mainly female （52.11%） and aged 19-64 （66.73%）. Based on the ICD code， the disease categories most involved in the use of acetaminophen were musculoskeletal system， connective tissue diseases or symptoms and signs （43.48%）； the top 3 clinical diagnoses were joint disease （25.59%）， fracture （9.95%）， and toothache （8.58%）. Among the 7 175 prescriptions with clear drug usage and dosage， 3 366 were in line with the recommendation of acetaminophen instruction， and 5.63% of the prescriptions exceeded the maximum dose limit of acetaminophen 2.0 g/d. There were 4 051 prescriptions exceeding the conventional limit of treatment duration （7 d）， and 1 336 prescriptions exceeding the limit of treatment duration （10 d）. The main factors affecting the duration of drug treatment ＞10 d were the region and type of medical institutions， the gender and age of patients， and the phenomenon of the duration of drug treatment ＞10 d was common in the primary medical institutions from southern Shaanxi， township health centers， the elderly and female patients. CONCLUSIONS There are some unreasonable clinical applications of acetaminophen in primary medical institutions of Shaanxi province， which are mainly manifested in inappropriate usage and dosage， unsuitable clinical diagnosis and drug duration. The region， type of medical institution， age and gender of patients will affect the duration of this drug prescription.

Ureteral stenosis and bladder contracture after radiotherapy for cervical cancer are challenging issues in urology. Ileal ureteroplasty combined with ileal bladder augmentation is a potential method to improve hydronephrosis and voiding function of patients, however, the surgical procedure is complex, with high surgical risks and numerous intraoperative and postoperative complications, which have hindered the widespread application of this surgical technique. This article introduces our hospital's experience through a typical surgical case. During the surgery, ileal substitution for bilateral ureters was performed in combination with ileal " N-shaped" augmentation. Two weeks after the surgery, the single-J stent was removed, and the urinary catheter was removed three weeks after the surgery. The patient achieved voluntary urination control with smooth voiding. Follow-up examinations at 3 months and 18 months postoperatively showed no hydronephrosis in the bilateral ureters, normal renal function, and a significantly expanded bladder capacity.

Objective To explore the effect of intermittent fasting combined with diversified management mode on weight loss of overweight and obese people. Methods A total of 120 overweight and obese patients were selected as research objects, and randomly divided into control group (n=60) and experimental group (n=60). The control group was given intermittent fasting, and the experimental group was given diversified management mode on the basis of the control group. Waist circumference, body mass, body mass index (BMI), waist-to-hip ratio and blood lipid level were compared between the two groups; the scores of hunger, satiety, satisfaction and the incidence of adverse reactions were compared between the two groups. Results After intervention, waist circumference, body mass, BMI, waist-to-hip ratio, total cholesterol (TC), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) in the experimental group were significantly lower, and high-density lipoprotein cholesterol (HDL-C) was significantly higher than that in the control group (P < 0.05). After intervention, the hunger score of the experimental group was significantly lower, and the satiety score and satisfaction score were significantly higher than those of the control group (P < 0.05). The total incidence of adverse reactions in the experimental group was 6.67%, which was significantly lower than 20.00% in the control group (P < 0.05). Conclusion The application of intermittent fasting combined with diversified management mode in overweight and obese people is better, which can improve the relevant clinical indicators and blood lipid levels, and has high safety.

Objective:To compare the efficacy of different drugs in reducing incidence of emergence agitation after tonsillectomy and adenoidectomy in the pediatric patients.Methods:Cochrane Library, PubMed, Web of Science, EMBASE, China National Knowledge Infrastructure, Wanfang and Chinese Biomedical Literature Databases were searched from inception to July 2023 for the randomized controlled trials involving interventions to reduce the incidence of emergence agitation after tonsillectomy and adenoidectomy in pediatric patients. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included studies. STATA 17.0 software was used to conduct a network meta-analysis according to the frequency-ology framework.Results:Twenty randomized controlled trials were finally included, involving 1 687 patients. Compared with placebo, 10 interventions could reduce the incidence of emergence agitation in pediatric patients after tonsillectomy and adenoidectomy, and the order of probability was as follows: dexmedetomidine ( OR and 95% confidence interval [ CI] 0.13 [0.09-0.20]), ketamine ( OR and 95% CI 0.15 [0.08-0.26]), clonidine ( OR and 95% CI 0.15 [0.05-0.50]), tramadol ( OR and 95% CI 0.16 [0.04-0.61]), remazolam ( OR and 95% CI 0.17 [0.06-0.47]), afentanil ( OR and 95% CI 0.22 [0.08-0.62]), remifentanil ( OR and 95% CI 0.24 [0.12-0.48]), desocine ( OR and 95% CI 0.29 [0.12-0.69]), fentanyl ( OR and 95% CI 0.31 [0.19-0.52]) and propofol ( OR and 95% CI 0.46 [0.24-0.86]). Four interventions cloud reduce the usage rate of postoperative rescue drugs, and the probability was ranked as follows: dexmedetomidine ( OR and 95% CI 0.19 [0.11-0.32]), tramadol ( OR and 95% CI 0.20 [0.10-0.42]), ketamine ( OR and 95% CI 0.49 [0.28-0.86]) and fentanyl ( OR and 95% CI 0.49 [0.32-0.77]). One intervention cloud reduce the incidence of postoperative nausea and vomiting: dexmedetomidine ( OR and 95% CI 0.54 [0.31-0.94]). Conclusions:Dexmedetomidine provides the best effect in reducing the incidence of emergence agitation after pediatric tonsillectomy and adenoidectomy.

Objective:To retrospectively analyze clinical characteristics and treatment of pemphigus/bullous pemphigoid (BP) complicated by herpes simplex virus (HSV) infection.Methods:Inpatients with pemphigus/BP complicated by HSV infection were collected from Wuhan No.1 Hospital from 2016 to 2021, and their clinical characteristics, treatment and follow-up results were retrospectively analyzed.Results:Among the 8 patients with pemphigus/BP complicated by HSV infection, there were 2 males and 6 females, and their age was 50.6 ± 8.3 years. Five of them were diagnosed with pemphigus vulgaris (PV), 1 with pemphigus foliaceus (PF), and 2 with BP. Seven were infected with HSV-1, and 1 with HSV-2. All the 8 patients were given systemic glucocorticoids and immunosuppressive agents for the treatment of pemphigus or BP, and were admitted to the hospital due to resistance to the treatment. Seven patients presented with exacerbation or recurrence of primary lesions, and 1 presented with enlarged lesions all over the body. HSV infection-induced lesions were located on the trunk in 4 cases, on the oral mucosa in 4, on the scalp in 3, and on the face in 2; lesions mainly manifested as irregular erosions with blood crusts, and some centrally umbilicated pustules; 7 patients had obvious pain at the lesional sites. During HSV infection, anti-desmoglein 1 antibody levels decreased in all the 6 patients with pemphigus, and anti-desmoglein 3 antibody levels decreased in 4 of the 5 patients with pemphigus vulgaris; anti-BP180 antibody levels decreased in 1 patient with BP, but increased in the other one with BP. After antiviral therapy at adequate doses for adequate durations (7- to 14-day treatment with valacyclovir alone or in combination with ganciclovir), HSV infection was controlled, the autoimmune bullous skin disorder intensity scores decreased compared with those before the antiviral therapy, and pain was significantly relieved in all the patients. No dose adjustment of glucocorticoids or other immunosuppressive agents was made during antiviral therapy in all patients.Conclusion:HSV infection should be considered when patients with pemphigus/BP suffer from recurrence or exacerbation and poorly respond to conventional treatment; for patients with pemphigus/BP complicated by HSV infection, systemic antiviral therapy at adequate doses can be used to control the disease condition without modifying the conventional immunosuppressive regimen.

Objective:To summarize clinical manifestations and histopathological features of granular parakeratosis (GP) after exposure to benzalkonium chloride.Methods:A retrospective analysis was performed on 7 GP cases with a history of benzalkonium chloride exposure in the Department of Dermatology at Wuhan No.1 Hospital from April to August 2022. Data were collected on the general condition, skin lesion manifestations, pathological examination, treatment, and follow-up of the patients, and retrospectively analyzed.Results:The 7 adult patients with GP typically presented with erythema and brown scales in the intertriginous area, exhibiting an annular distribution pattern. All the 7 patients reported recent exposure to disinfectants containing benzalkonium chloride. A total of 10 skin biopsies were taken from the 7 patients. Histopathological examination showed characteristic hyperkeratosis and fine blue-gray parakeratotic granules in the stratum corneum. All skin lesions improved 1 month after cessation of exposure to benzalkonium chloride.Conclusion:GP has a distinct clinical pattern and histopathological manifestations, and a history of exposure to benzalkonium chloride can be helpful for the diagnosis of GP.

Objective:To evaluate and compare efficacy of intravenous immunoglobulin (IVIG) versus recombinant human tumor necrosis factor-α receptor Ⅱ:IgG Fc fusion protein (rhTNFR:Fc) in the treatment of toxic epidermal necrolysis (TEN) .Methods:Clinical data were collected from patients with TEN treated with IVIG or rhTNFR:Fc in Wuhan No.1 Hospital from 2013 to 2019. There were 11 patients in the IVIG group, including 3 males and 8 females, aged 25-72 years, and the median TEN-specific severity-of-illness score (SCORTEN) was 3 points; there were 10 patients in the rhTNFR:Fc group, including 5 males and 5 females, aged 32-84 years, and the median SCORTEN was 2 points. These patients all showed no response to the 5-day treatment with prednisolone acetate at a dose of 0.6-1.0 mg·kg -1·d -1, and then received IVIG at a dose of 400 mg·kg -1·d -1 for 5 consecutive days, or subcutaneous injection of rhTNFR:Fc at a dose of 25 mg every other day for 4-6 sessions. Changes in skin lesions and adverse events were recorded in the 2 groups. Statistical analysis was carried out by using Mann-Whitney U test. Results:Compared with the rhTNFR:Fc group, the IVIG group showed a significant decrease in the time to onset of reduction of skin lesion exudate (1.73 ± 1.19 days vs. 3.00 ± 1.56 days, P < 0.05) , time to onset of pain relief in the lesion area (1.64 ± 1.28 days vs. 3.70 ± 1.63 days, P < 0.05) , time to lightening of color of the lesion base (2.45 ± 1.12 days vs. 3.90 ± 1.59 days, P < 0.05) , time to onset of new epidermis growth (3.09 ± 1.13 days vs. 5.20 ± 1.22 days, P < 0.05) , and in the time to onset of lesion drying at the intertriginous sites (4.82 ± 2.22 days vs. 7.90 ± 3.14 days, P < 0.05) . However, there was no significant difference in the length of hospital stay between the IVIG group (17.70 ± 8.33 days) and rhTNFR:Fc group (16.70 ± 4.71 days, P > 0.05) . No adverse reactions were observed during the treatment, and no recurrence or complications were found in the 21 patients during the follow-up of 6 months. Conclusion:IVIG and rhTNFR:Fc are both effective in the treatment of TEN, but IVIG is superior to rhTNFR:Fc in terms of the time to onset of pain relief, skin lesion exudate reduction and epidermal growth.

The clinical application of immune checkpoint inhibitors (ICIs) has significantly improved the prognosis of hepatocellular carcinoma (HCC) patients. With the widespread applica-tion of ICIs in HCC, the management of immune-related adverse events (irAE) gained more and more attention. However, the complicated disease characteristics and various combination therapies in HCC throw out challenges to irAE management. Therefore, the editorial board of the 'Chinese expert consensus on the management of immune-related adverse events of hepatocellular carcinoma treated with immune checkpoint inhibitors (2021 edition)' organizes multidisciplinary experts to discuss and formulate this consensus. The consensus focuses on issues related to HCC irAE manage-ment, and puts forward suggestions, in order to improve standardized and safety clinical medication, so as to maximize the benefits of immunotherapy for patients.

OBJECTIVE: To investigate the CT findings of patients with different clinical types of coronavirus disease 2019 (COVID-19). METHODS: A total of 67 patients diagnosed as COVID-19 by nucleic acid testing were collected and divided into 4 groups according to the clinical stages based on . The CT imaging characteristics were analyzed among patients with different clinical types. RESULTS: Among 67 patients, 3(4.5%) were mild, 35 (52.2%) were moderate, 22 (32.8%) were severe, and 7(10.4%) were critical ill. No significant abnormality in chest CT imaging in mild patients. The 35 cases of moderate type included 3 (8.6%) single lesions, the 22 cases of severe cases included 1 (4.5%) single lesion and the rest cases were with multiple lesions. CT images of moderate patients were mainly manifested by solid plaque shadow and halo sign (18/35, 51.4%); while fibrous strip shadow with ground glass shadow was more frequent in severe cases (7/22, 31.8%). Consolidation shadow as the main lesion was observed in 7 cases, and all of them were severe or critical ill patients. CONCLUSIONS CT images of patients with different clinical types of COVID-19 have characteristic manifestations, and solid shadow may predict severe and critical illness.
