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.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objective:To assess the prevalence of metabolic syndrome(MS) and its relationship with hyperuricemia(HUA) in perimenopausal women in Anning city, Yunnan province.Methods:This is a cross-sectional survey. In May 2021, a multi-stage stratified sampling method was used to collect demographics and clinical data [ethnicity, living community, height, weight, waist circumference, blood pressure, fasting plasma glucose, triglycerides(TG), serum uric acid, high density lipoprotein-cholesterol(HDL-C), alanine transaminase(ALT), etc] in a total of 6 721 perimenopausal women aged 45-60 years.Results:A total of 6 721 perimenopausal women were included in this study. The prevalences of MS and HUA were 14.05%(95% CI 13.22%-14.88%) and 6.46%(95% CI 5.88%-7.07%), respectively. The average age, HDL-C, urea, direct bilirubin, and albumin levels in the perimenstrual HUA population were lower than those in the non-HUA population while the levels of TG, ALT, heart rate, body mass index(BMI), and creatinine were higher(all P<0.05). The prevalence of HUA in perimenopausal women with ethnic minorities and family history of chronic diseases was higher than that in Han nationality and without family history of chronic diseases. The prevalence of MS in perimenopausal women was increased with the increase of serum uric acid( Z=-15.313 8, P<0.001). Multivariate logistic regression model showed that HUA was positively correlated with MS( OR=1.526, 95% CI 1.192-1.954) after adjusting for covariates such as BMI and ethnicity, and the incidence of MS in perimenopausal women in HUA group was 1.526 folds higher than that in non-hyperuricemia group. Conclusion:HUA is highly positively correlated with MS in perimenopausal women. The management of uric acid level in perimenopausal women should be strengthened.

Objective To evaluate the diagnostic value of endoscopic ultrasonography(EUS)for common bile duct(CBD)stones before endoscopic retrograde cholangiopancreatography(ERCP). Methods Data of patients with suspected CBD stones admitted to The First People′s Hospital of Hangzhou from July 2012 to July 2013 were reviewed. Diagnostic efficiency and rates of complications were analyzed between patients undergoing EUS(EUS group)and MRCP(MRCP group)before ERCP, and between patients who underwent EUS and ERCP in different sessions(non-one-session group)with those in one session(one-session group). Results A total of 657 patients were included. With ERCP and follow-up results as the gold standard, the sensitivity(97.5% VS 88.4%), accuracy(96.3% VS 88.0%)and negative predictive value(88.9% VS 60.0%)of EUS in the diagnosis of CBD stones were significantly higher than those of MRCP(P<0.05). There were no significant differences between one-session group and non-one-session group in the sensitivity(97.5% VS 97.4%), specificity(91.7% VS 90.0%), positive predictive value(98.3% VS 97.4%), negative predictive value(88.0% VS 90.0%), and accuracy (96.6% VS 95.9%)in diagnosis of CBD stones(P>0.05). There were no significant differences in incidence of postoperative complications of ERCP between EUS and MRCP group[5.4%(13/242)VS 5.1%(21/415),P>0.05],and between one-session group and non-one-session group[5.5%(8/145)VS 5.2%(5/97),P>0.05].Conclusion Preoperative EUS before ERCP could increase diagnostic sensitivity and negative pridictive value of CBD stones without increasing the incidence of complications.

Objective At present, the methods of separating and identifying nasopharyngeal cancer stem cells are not yet mature.This study was to explore the methods of culturing nasopharyngeal cancer stem cell microspheres and identify the cancerous stem cell biological features of CNE-2 cell microspheres. Methods We conducted suspension culture of human nasopharyngeal cancer CNE2 cells and C666-1 cells in serum-free medium ( SFM) containing growth factors.Then we measured the proportion of CD133 +cells in CNE2 monolayer ( CNE2-MN) and CNE2 microsphere cells ( CNE2-SC) by flow cytometry, determined their in vitro invasiveness through Transwell chamber experiments, and detected their in vivo tumorigenicity via nude mouse experiments.We ob-served the differentiation potency of the CNE2-SCs in the adherent-cultured serum-containing medium and detected the expressions of the cancer stem cell-related genes Bmi-1, Oct4, and Twist1 in CNE2-MN and CNE2-SCs by flow cytometry and RT-PCR analysis. Results In the special blend of SFM, both of the cell lines can form microspheres that can be stably transferred.Fresh SFM prepara-tion, substituting cell separation agent Accutase for pancreatic enzyme for transfer, and maintaining the state of cell suspension contrib-uted to the formation and proliferation of microspheres.Adherent culture with serum-containing medium induced the differentiation of CNE2-MN cells, which exhibited no significant difference from the CNE2 microsphere cells.The CD133 +cells accounted for 98.79%in the CNE2 microspheres, significantly higher than 0.98%in the CNE2 cells (P<0.01).Compared with the CNE2-MN cells, the CNE2-SCs showed highly increased expressions of Bmi-1, Oct4, and Twist1 (P<0.01).The numbers of membrane-penetrating cells in the CNE2-SCs and CNE2-MN cells were 122 ±6 and 36 ±7 per visual field, the former with a stronger invasive ability than the latter genesis of 1 ×106 CNE2-SCs vs that of the same number of CNE2 -MNcells was (2.332 ±0.549) cm 3 sv (0.669 ±0 .278) cm3 ( P<0.01). Conclusion Using suspension culture with a specially prepared SFM, nasopharyngeal cancer CNE2 microsphere cells can be obtained, in which there are large numbers of cancer stem cells.This culture method may provide a base for further studies of naso-pharyngeal cancer stem cells.

ObjectiveTo observe the effects of norepinephrine and dobutamine (NE+Dobu) on hemodynamics, tissue perfusion and oxygen metabolism in elderly patients with septic shock at different levels of mean arterial pressure (MAP). MethodsAfter aggressive fluid resuscitation,norepinephrine and dobutamine were administered in 18 elderly patients with septic shock to correct hypotension. The rate of dobutamine infusion was 5 ug. kg<'-1>. min<'-1> Norepinephrine was titrated to maintain MAP at levels of 65 mm Hg, 75 mm Hg and 85 mmHg. Four hours later, the changes of hemodynamics, oxygenation index, blood lactate, renal function and gastric pCO<,2> at every MAP level were observed. ResultsThere were no significant differences in heart rate (HR), pulmonary arterial wedge pressure (PAWP), volume of oxygen (VO<,2>), Blood lactate, pH value, △pCO<'2> and creatinine clearance rate (CCr) among the MAP levels of 65 mm Hg, 75 mm Hg and 85 mm Hg ( all P>0.05). Compared with MAP 65 mm Hg, cardiac index (CI), systemic vascular resistance index (SVRI), oxygen delivery over oxygen extraction ratio were obviously higher at MAP 75 mm Hg and 85 mm Hg [4.7±0.6, 5.1±0.7 vs. 4.0±0.6; 1162±278, 1276±319 vs. 1011±225; (697±53) ml. min<'1>. m<'2>,(711±68)ml. min<'-1>. m<'2> vs. (634±70) ml · min<'-1> · m<'2>; (0.28±0.02)%,(0.27±0.02)% vs. (0.25±0.02) %, respectively, all P<0.05). The urinary output at MAP levels of 65 mm Hg, 75 mm Hg and 85 mm Hg were (98±43)ml/h, (91±54) ml/h and(74±49)ml/h repectively, and only the differences between MAP 75 mm Hg and MAP 65 mm Hg had statistical significance (P<0.05).ConclusionsAfter aggressive fluid resuscitation, hemodynamics and renal function are improved at MAP 75 mm Hg after administration of norepinephrine and dobutamine in elderly patients with septic shock. It should be considered that MAP is appropriately increased in elderly patients with septic shock.

Objective To investigate the effects of enriched environment and impoverished environment on brain function after hypoxic-ischemic brain damage(HIBD).Methods Three-day-old SD rats,which were divided into enriched environment group(EE),standard environment group(SE) and impoverished environment group(IE) by random digits table were used to establish HIBD model.The sham-operation rats served as control group.Different environment stimulations were administrated to the rats respectively since the 2nd day after HIBD.On the 32nd day,hanging test and incline plane test were carried out to evaluate the sensorimotor function.Morris water maze was used to evaluate the learning and memory ability.The expression of GFAP in the cortex and hippocampus was measured by the method of immunohistochemistry.Results The brain function of IE group was much worse than that of SE group(P0.05).Immunohistochemical analysis showed the expression of GFAP in the cortex and hippocampus of Sham group was significantly lower than that of other groups(P
