BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

OBJECTIVES: We propose a Contrastive Regional Attention and Prior Knowledge-Infused U-Transformer model (CRAKUT) to address the challenges of imbalanced text distribution, lack of contextual clinical knowledge, and cross-modal information transformation to enhance the quality of generated radiology reports. METHODS: The CRAKUT model comprises 3 key components, including an image encoder that utilizes common normal images from the dataset for extracting enhanced visual features, an external knowledge infuser that incorporates clinical prior knowledge, and a U-Transformer that facilitates cross-modal information conversion from vision to language. The contrastive regional attention in the image encoder was introduced to enhance the features of abnormal regions by emphasizing the difference between normal and abnormal semantic features. Additionally, the clinical prior knowledge infuser within the text encoder integrates clinical history and knowledge graphs generated by ChatGPT. Finally, the U-Transformer was utilized to connect the multi-modal encoder and the report decoder in a U-connection schema, and multiple types of information were used to fuse and obtain the final report. RESULTS: We evaluated the proposed CRAKUT model on two publicly available CXR datasets (IU-Xray and MIMIC-CXR). The experimental results showed that the CRAKUT model achieved a state-of-the-art performance on report generation with a BLEU-4 score of 0.159, a ROUGE-L score of 0.353, and a CIDEr score of 0.500 in MIMIC-CXR dataset; the model also had a METEOR score of 0.258 in IU-Xray dataset, outperforming all the comparison models. CONCLUSIONS The proposed method has great potential for application in clinical disease diagnoses and report generation.

Traditional Chinese medicine （TCM） has a long history of application in China and has consistently played a vital role in treating diseases and saving lives. TCM prescriptions （compounds） constitute the primary form of clinical TCM treatment and significantly differ from western medicine （chemicals） due to the diverse composition and chemical constituents of TCM （compounds）. Nevertheless， the potential multi-component， multi-target， and multi-pathway action characteristics of TCM prescriptions also demonstrate their possible （complementary） therapeutic advantages when compared with single-component chemical drugs. Therefore， driven by the development of modern science and technology and the demands of the modernization and internationalization of TCM， modern theories regarding the complexity of TCM prescription effects have been continuously proposed： Different from the abstract language of traditional prescription theory， the modern TCM prescription theory is more inclined to illustrate the connotation of prescription compatibility concretely and vividly from an experimental and scientific perspective. In this paper， new theories on the complexity of TCM prescriptions proposed in recent years are summarized to provide research references and ideas for the greater role of TCM prescriptions and a better scientific understanding.

Objective:To investigate the effects of different doses of rosuvastatin on blood lipid levels and 1-year outcomes in patients undergoing coronary artery bypass grafting.Methods:A total of 106 patients who underwent coronary artery bypass grafting at the Affiliated Hospital of Jining Medical University from February 2020 to February 2022 were prospectively selected and randomly divided into two groups using a random number table. The high-dose group (53 cases) was treated with 20 mg/d rosuvastatin, while the low-dose group (53 cases) was treated with 10 mg/d rosuvastatin. The two groups were compared after treatment in terms of the clinical efficacy, blood lipid levels [total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C)], cardiac function indicators [left ventricular end diastolic diameter (LVDD), left atrial diameter (LAD), left ventricular ejection fraction (LVEF), one-year follow-up [recurrence, readmission, death, major adverse cardiovascular events (MACE)], and adverse reactions (liver injury, elevated creatine kinase, gastrointestinal reactions, rash).Results:The total effective rate of the high-dose group was 94.34%(50/53) higher than that of the low-dose group, which was 77.36%(41/53) ( P<0.05); After treatment, the levels of TC, TG, and LDL-C in both groups decreased, while the level of HDL-C increased (all P<0.05), and the levels of TC, TG, and LDL-C in the high-dose group were lower than those in the low-dose group, while the level of HDL-C was higher than that in the low-dose group (all P<0.05); After treatment, LVDD and LAD in both groups decreased, while LVEF increased (all P<0.05), and LVDD and LAD in the high-dose group were lower than those in the low-dose group, while LVEF was higher than that in the low-dose group (all P<0.05); After a one-year follow-up, the recurrence rate of the high-dose group was 7.55%(4/53), and the readmission rate was 5.66% (3/53), both lower than those of the low-dose group [26.42%(14/53), 20.75%(11/53)] (all P<0.05). There was no statistically significant difference in case fatality rate, MACE, and incidence of adverse reactions between the two groups (all P>0.05). Conclusions:The use of high-dose rosuvastatin in patients undergoing coronary artery bypass grafting can effectively reduce blood lipid levels, improve cardiac function, and has high safety. It is worthy of clinical application.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Demographic characteristics, disease types and proportions, main complications, causes of serious or life-threatening conditions, important treatment measures and outcomes were summarized, and causes of death were also analyzed and discussed.Results:A total of 1 057 patients with critical illnesses were collected, with a male-to-female ratio of 1∶1.11, and 64.81% of them aged 18 to 65 years. The types of diseases mainly included drug eruptions (332 cases) , connective tissue diseases (226 cases) , bullous skin diseases (104 cases) , psoriasis (57 cases) , erythroderma (45 cases) , infectious skin diseases (67 cases) , etc. Among them, psoriasis (39 cases) and erythroderma (32 cases) mostly occurred in males, and connective tissue diseases (168 cases) mostly occurred in females. Common complications mainly involved infections, important organ damage or dysfunction, hypoalbuminemia, and fluid, electrolyte and acid-base imbalances. A total of 94 patients were diagnosed with life-threatening conditions, which were found to be mainly caused by primary skin diseases, hematologic abnormalities, respiratory failure, nervous system abnormalities, renal failure, sepsis, fluid, electrolyte and acid-base imbalances, etc. During the management of critical illnesses, 43 patients were treated with high-dose glucocorticoid pulse therapy, 264 were treated with gamma-globulin pulse therapy, 355 were transfused with other blood products, and 34 received special therapies such as hemoperfusion/immunoadsorption therapy, plasma exchange, dialysis, artificial liver support therapy; 42 patients were transferred to the intensive care unit (ICU) , 12 were transferred to the department of surgery for operations, and 12 were transferred to the department of obstetrics and gynecology for delivery or induction of labor. After treatment, 989 patients (93.57%) achieved improvement and were discharged. A total of 14 patients (1.32%) died, of whom 7 died of secondary sepsis, 2 died of severe pulmonary infections, 2 died of asphyxia caused by respiratory mucosa shedding-induced airway obstruction, the other 3 died of gastrointestinal hemorrhage, cerebral hemorrhage and neuropsychiatric systemic lupus erythematosus, respectively.Conclusions:Critical cases in the dermatological ward mainly suffered from serious skin diseases such as severe drug eruptions, connective tissue diseases and bullous skin diseases, as well as complications such as severe underlying diseases, severe organ dysfunction, sepsis or severe fluid, electrolyte and acid-base imbalances. In terms of treatment, it is of critical significance to make a clear diagnosis and assess the severity of disease as early as possible, monitor and prevent possible complications, and to consult with specialists in relevant disciplines in time.

OBJECTIVETo discuss the feasibility of terminal intestinal exteriorization (exteriorization without ileostomy) in laparoscopic anterior resection for rectal cancer.

METHODSClinicopathological data of 77 patients undergoing laparoscopic anterior resection for low rectal cancer in our department from January 2011 to December 2013 were retrospectively analyzed. After laparoscopic rectal resection, 32 patients received terminal intestinal exteriorization (exteriorization group) and 45 patients received preventive ileostomy (ileostomy group). Anastomosis-related, stoma-related and intestinal stoma closure-related morbidity was compared between the two groups.

RESULTSThere were no significant differences in operative time, blood loss and overall hospital stay between the two groups (all P>0.05). The total hospital cost was (5.39±1.74)×10(4) yuan in the exteriorization group, and (6.98±1.37)×10(4) yuan in the ileostomy group(P<0.01). The incidences of postoperative anastomotic fistula was not significantly different between the two groups(P>0.05). Three patients(9.4%) developed anastomotic leak in the exteriorization group and 2(4.4%) in the ileostomy group. The anastomotic leak was managed by opening the external intestinal wall and maturating an ileostomy under local anaesthesia. All these 5 patients were cured with nutritional support, antibiotics, continuous local drainage. In the exteriorization group, 5 patients had complications related to stoma and intestinal stoma closure operation(15.6%), which was lower than(42.2%) in the ileostomy group(P=0.013).

CONCLUSIONTerminal intestinal exteriorization in laparoscopic anterior resection is a safe and feasible surgical procedure with little trauma and less hospital cost, which can be an alternative as a prophylactic treatment for patients with high risk of anastomotic leak.
