A 51-year-old male presented with nasal obstruction, followed by progressive hearing loss and blurred vision. Imaging identified space-occupying lesions in the paranasal sinuses, orbits, and paraspinal regions, while laboratory tests confirmed positive anti-proteinase 3 anti-neutrophil cytoplasmic antibody(PR3- ANCA) immunoglobulin G (IgG)and markedly elevated serum IgG4. Despite treatment with corticosteroids, immunosuppressants, and radiotherapy, the patient exhibited steroid dependency with relentless disease progression. Following multidisciplinary consultation, a diagnosis of inflammatory myofibroblastic tumor (IMT) coexisting with ANCA- associated vasculitis (AAV) was favored, though IgG4-related disease remained a critical differential. Ultimately, profound immunosuppression precipitated a severe herpesvirus infection, leading to disseminated intravascular coagulation and multiple organ dysfunction syndrome. This case underscores the rarity and diagnostic complexity of concurrent IMT and AAV, highlights the therapeutic dilemma of balancing primary disease control against fatal opportunistic infections, and emphasizes the critical role of multidisciplinary collaboration in the diagnosis and treatment of complex diseases.

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 introduce the method and results of modeling validation of the treatment planning system used in the first Mevion proton therapy system in China.Methods The SOBP(Spread-Out Bragg Peak)beams in water were designed according to the TG-185 report.The treatment plans in water were designed according to the TG-350 report.The treatment plans of patients were designed on the CT images.The plane dose of each beam was measured by using the MatriXX ONE ioni-zation chambers at different depths in the water,and the measurment results were compared with the TPS calculated results to verify the accuracy of the output doses,the error requirements were 2％/2 mm.Results Except for the distal fall-off position,the doses deviation at the SOBP beams center were less than 3％,and the γ analysis pass rates of plane doses were more than 90％.The measured results of the treatment plan beams were within the tolerance of deviation,and the output doses of the beams without or with static adaptive aperture were more accurate in general.With the decrease of beam energy,the error of dose calculation will increase.Conclusion According to the accuracy requirements of the planning system calculation and treat-ment system implementation,the proton therapy system supporting the treatment planning system has been modeled.Some basic performance such as IDD and beam spot is consistent with the actual measurement,and the TPS modeling conforms to the actual performance of the machine executing when calculating the same proton radiotherapy plan.

Objective To explore how digital and intelligent technologies can optimize the storage allocation and picking paths for Traditional Chinese medicine decoction pieces.Methods Based on prescription information and medicine data from the hospital information system(HIS),this study employs MATLAB programming to use an integer linear programming(ILP)algorithm for optimizing the storage allocation of Traditional Chinese medicine decoction pieces.Additionally,a greedy algorithm is applied to optimize the picking paths to reduce the picking distance for pharmacists.Finally,an independent samples paired t-test is used to analyze the experimental data to verify the significance of the optimizations.Results A total of 7 734 prescriptions were collected from the HIS.The results of storage optimization showed that the total distance before optimization was(87.58±0.29)m,which was reduced to(85.35±0.28)m after optimization(P﹤0.000 1).The picking path optimization results showed that the picking path was(85.35±0.28)m before optimization and(40.06±0.11)m after optimization(P﹤0.000 1).The results of the independent samples paired t-test indicate that the path was significantly reduced after both storage and picking path optimizations,with statistical significance.Conclusion By using digital and intelligent methods,informatics pharmacists can effectively shorten the picking paths for Traditional Chinese medicine decoction pieces,improve dispensing efficiency,and reduce patient waiting times.

Objective:To evaluate the safety and efficacy of enteromorpha prolifera enzymatic hydrolysate in alleviating scalp sensitive symptoms.Methods:The inhibitory effects of different concentrations of enteromorpha prolifera hydrolysate on tumor necrosis factor (TNF)-α, interleukin (IL)-1α, IL-6, and other inflammatory factors were observed through in vitro experiments. Subsequently, the abilities to scavenge [2, 2＇-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)] (ABTS) and to promote proliferation of mouse fibroblasts were evaluated. A prospective study was conducted on 20 patients with scalp sensitivity at Qingdao Hiser Hospital Affiliated to Qingdao University from April 2023 to October 2023. The patients included 2 males and 18 females with an average age of (34.9±10.3) years. They were treated with a scalp essence containing 10% enteromorpha enzymatic hydrolysate for consecutive 28 days. Changes in scalp cuticle water content, transepidermal water loss (TEWL), and oil content were measured before and after 14 and 28 days of treatment. Expert interviewers assessed the skin irritation test to elucidate any undesirable side effects.Results:The results of in vitro experiments demonstrated that enteromorpha protophora enzymatic hydrolysate at different concentrations exhibited inhibitory effects on the expression of IL-1α, IL-6, and TNF-α, while it also displayed a dose-dependent ability to scavenge ABTS free radicals. Furthermore, it effectively promoted the proliferation of mouse fibroblasts, resulting in a significant increase of 43.22% in fibroblast viability when the concentration of enteromorpha protophora enzymatic hydrolysate was 0.10%. The outcomes from clinical trials revealed that after using a scalp essence containing enteromorpha protophora enzymatic hydrolysate for 14 and 28 days, there were significant improvements observed in terms of increased water content in the scalp epidermis, along with decreased oil content and TEWL value (all P< 0.001). Moreover, remarkable effective rates were achieved for treating various scalp conditions including redness (80.0%, 16/20), dandruff (80.0%, 16/20), itching (85.0%, 17/20), stinging sensation (90.0%, 18/20), and tightness (80.0%, 16/20) after using the scalp essence for 28 days. Adverse effects on the skin were not observed in any subject during the test period. Conclusions:The enzymatic hydrolysate of enteromorpha demonstrates both safety and efficacy in alleviating symptoms associated with scalp sensitivity.

Diabetes, hypertension, and dyslipidemia, collectively referred to the " Three Highs, " represent increasingly prevalent metabolic risk factors in China. Many individuals experience all three conditions concurrently, significantly heightening the risk of cardiovascular disease and mortality. Although the National Metabolic Management Center(MMC) has been established for over eight years and has its unique features, the awareness, treatment, and control rates of these diseases in China remain low, and the efficiency of community management is insufficient. According to the previous two editions of management guidelines and the most recent domestic and international diagnostic and treatment guidelines, this paper conducts an in-depth analysis of the operational experience and management strategies of the MMC. Its aim is to improve the efficiency of grassroots MMC mode management for " Three Highs" patients and ensure that patients receive more standardized management.
