Objective:To explore the safety, economic benefits, and clinical application effect of the new practical patent open window central venous catheter combination dressing (Patent No.ZL 202121652858.8).Methods:From October 2022 to October 2023, a randomized controlled trial was conducted. A total of 120 tumor patients in Yunnan Cancer Hospital with indwelling central venous catheters who met the inclusion and exclusion criteria were randomly divided into three groups at a ratio of 1∶1∶1 with random digit table, with 40 patients in each group: control group 1, control group 2, and the experimental group. In control group 1, Smith & Nephew IV 3000 dressing was used, in control group 2, 3M transparent dressing was used; and in the experimental group, the self - developed fenestrated central venous catheter combined dressing by the researchers was used for catheter maintenance. The skin surface bacterial colonization, the occurrence of medical adhesive-related skin injuries, catheter maintenance time, and maintenance costs were compared among the three groups.Results:In control group 1, there were 21 males and 19 females, with an average age of (51.53 ± 12.01) years. In control group 2, there were 22 males and 18 females, with an average age of (54.00 ± 11.03) years. In the experimental group, there were 19 males and 21 females, with an average age of (53.60 ± 9.41) years. During the 72 - hour observation period, 1, 3, and 2 cases of bacterial colonization occurred in control group 1, control group 2, and the experimental group respectively, and there was no significant difference among the three groups ( χ2 = 1.10, P = 0.577). No medical adhesive - related skin injury occurred in the experimental group, and there was a significant difference compared with the 4 cases in control group 2 ( χ2 = 4.21, P = 0.040). The average catheter maintenance time and maintenance cost in the experimental group were (15.20 ± 1.56) minutes and (8.11 ± 1.35) yuan respectively. Compared with (21.05 ± 3.31) minutes and (13.16 ± 1.03) yuan in control group 1, the differences were statistically significant ( t = 5.85, 5.05, both P<0.001). Compared with (21.08 ± 3.00) minutes and (15.17 ± 1.63) yuan in control group 2, the differences were also statistically significant ( t = 5.88, 7.06, both P<0.001). Conclusions:The open-window central venous catheter combination dressing designed in this study can effectively reduce the incidence of medical adhesive-related skin injury, and also has a better role in saving maintenance time and reducing maintenance costs, especially for patients who need repeated dressing changes at the puncture point for treatment with the advantages of, convenience, economy, speed, firm fixation and safety.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the predictive value of circulating free DNA(cfDNA)combined with interleukin 10(IL-10)in predicting central nervous system infiltration(CNSI)in diffuse large B-cell lymphoma(DLBCL).Methods:The clinical data of 63 patients with DLBCL in our hospital from May 2021 to April 2023 were retrospectively analyzed.The 63 patients were divided into CNSI group(15 cases)and non-CNSI group(48 cases)base on whether CNSI occurred.The age,sex,Ann Arbor stage,ECOG score,IPI risk,CNS-IPI risk,number of extranodal sites involved,bone marrow involvement,hypertrophic disease,B symptoms,source cells,glucose quantification,Pandy test,cerebrospinal fluid(CSF)chlorine,CSF nucleated cell count,CSF protein,peripheral blood cfDNA,and IL-10 status were compared between the two groups.The correlation between cfDNA,IL-10 in peripheral blood and CSF protein was analyzed by Pearson correlation analysis.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of peripheral blood cfDNA and IL-10 on secondary CNSI in DLBCL patients.The last follow-up was on November 30,2023.Kaplan-Meier method was used to calculate the time of secondary CNSI in the non-CNSI group.Results:The IPI risk,CNS-IPI risk,number of extranodal sites involved,and CSF protein in the CNSI group were significantly higher than those in the non-CNSI group(all P＜0.05).The levels of cfDNA and IL-10 in peripheral blood of CNSI group were significantly higher than those of non-CNSI group(both P＜0.01).cfDNA and IL-10 in peripheral blood were both positively correlated with CSF protein(r=0.402 4,0.315 1).ROC curve analysis showed that peripheral blood cfDNA and IL-10 had certain predictive value for CNSI,and the area under the curve(AUC)was 0.829 and 0.742,respectively.The AUC of the combined detection was 0.910,with a sensitivity of 80.00％and a specificity of 93.70％.The diagnostic efficacy was significantly higher than that of the two prediction values alone.The median follow-up time was 20(6-31)months.Non-CNSI patients were grouped based on peripheral blood cfDNA combined with IL-10 positive or negative pairs.The time of secondary CNSI in positive group was significantly shorter than that in negative group(P＜0.05).Conclusion:cfDNA and IL-10 in peripheral blood of DLBCL patients with CNSI are significantly increased,and the combined detection of cfDNA and IL-10 has good predictive value for CNSI.

Objective:To investigate factors influencing frequent episodes (≥ 4 episodes within 1 year) in children with moderate-to-severe atopic dermatitis (AD) in China.Methods:A national multicenter cross-sectional study was conducted. Patients under the age of 18 years diagnosed with moderate-to-severe AD were enrolled at dermatology clinics in 18 medical institutions across 12 provinces and municipalities in China between June 12 and August 8, 2023. At the time of the visit, their guardians completed a structured questionnaire covering demographic characteristics, clinical features of AD, personal and family history, factors associated with frequent episodes of moderate-to-severe AD, compliance with treatment, and disease awareness. Statistical analyses included t tests, one-way analysis of variance, rank-sum tests, and chi-square tests, with multiple-response analysis applied for multiple-choice questions. Results:A total of 965 valid questionnaires were collected, and 965 children with moderate-to-severe AD were included. Among them, there were 531 males and 434 females, 678 (70.3%) were aged 2 - < 12 years, 837 (86.7%) were from urban areas, the age at onset was 2.47 ± 3.03 years, and the median frequency of AD episodes in the past year was 4 times. These children were divided into 2 groups based on the median episode frequency: < 4-episode group (439 cases, 45.5%) and ≥ 4-episode group (526 cases, 54.5%). Compared with the < 4-episode group, children in the ≥ 4-episode group showed younger ages at onset (2.22 ± 2.98 years vs. 2.76 ± 3.06 years, P = 0.006) and higher proportions of patients with comorbid allergic diseases in both the children themselves (82.9% [436/526] vs. 69.7% [306/439], χ2 = 23.42, P < 0.001) and their relatives (66.0% [347/526] vs. 57.4% [252/439], χ2 = 7.46, P = 0.006). Children in the ≥ 4- episode group also had higher monthly usage of moisturizers (150 [30, 300] g vs. 60 [6, 200] g) and daily frequency of moisturizer use, greater disease awareness, but more severe fear of medication use (all P < 0.05). The region and the human development index level were both significantly associated with the episode frequency (both P < 0.001), with the highest proportion of children from South China in the ≥ 4- episode group (36.3%, 191/526). Children in the ≥ 4-episode group also had a longer duration of topical glucocorticoid use than those in the < 4-episode group ( Z = -2.21, P = 0.027). External triggers associated with AD episodes mainly included heat exposure (50.36%, 486/965), hot water bathing (40.73%, 393/965), seafood (23.52%, 227/965), and dust mites (33.37%, 322/965) . Conclusion:In children with moderate-to-severe AD in China, factors influencing frequent episodes may include residence in southern or economically developed regions, earlier age at onset, having a personal or family history of allergic diseases, and fear of medication use.

6-Thioguanine(6-TG)is an antineoplastic agent used in treatment of acute leukemia.However,significant interindividual variability in dosing regimens and frequent clinical manifestations of hepatotoxicity and myelosuppression as adverse effects have affected its therapeutic efficacy.Consequently,the development of rapid analytical methods for 6-TG in clinical samples,enabling continuous therapeutic drug monitoring of plasma concentrations,holds substantial significance in optimizing dosage regimens,mitigating adverse reactions,and investigating drug metabolism mechanisms.In this study,multi-tipped gold nanostars(AuNSs)were prepared.With bis-(p-sulfonylphenyl)phenylphosphine molecule as the protecting agent and internal standard molecule,the AuNSs were assembled onto a highly sensitive surface-enhanced Raman(SERS)substrate for developing a ratio-based SERS quantitative analysis method for 6-TG in serum.The AuNSs containing multiple tips and gaps exhibited strong local surface plasmon resonance effect and SERS activity,ensuring the sensitivity of the analytical method.Furthermore,the introduction of internal standard molecules could improve the reproducibility,which guaranteed this method suitable for rapid analysis of drug molecules in complex samples.Quantitative analysis of 6-TG was achieved with linear detetion range of 1.0×10?4-1.0 mmol/L.In the spiked recovery experiments of serum,the RSD was less than 5.32%,and the recoveries were 94%-104%,which proved that this method could be used for rapid quantitative determination of 6-TG in serum.This method provided a powerful tool for studying drug pharmacokinetics,which could promote the optimization of the usage methods of anti-cancer drugs,and it was expected to further enhance the clinical efficacy and safety of 6-TG,enabling it to achieve the best therapeutic effect.
