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.

Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.

Objective:To observe the effects of Huatan Quyu Decoction on the protein expressions of β-catenin and GSK-3 β and the expression of anticardiolipin antibody and β-amyloid protein related to cognitive function in rats with vascular dementia based on Wnt/β-catenin signal pathway.Methods:A total of 96 male SD rats were divided into blank group, model group, Donepezil hydrochloride group and Huatan Quyu Decoction low-, midium-, high-dosage group according to random number table method, with 16 rats in each group. Except for the blank group, the rat model of vascular dementia was prepared by modified 2-VO method. Huatan Quyu Decoction low-, medium- and high-dosage groups were administrated with Huatan Quyu Decoction 6.1, 12.1 and 24.2 g/kg, respectively; the Western medicine group was administrated with Donepezil hydrochloride 0.5 mg/kg; the blank group and the model group were administrated with the same amount of normal saline for 28 consecutive days. On the 1st, 7th, 14th and 28th day after administration, the learning and memory ability of rats was evaluated by Morris water maze test, the levels of ACA and Aβ in serum were measured by enzyme linked immunosorbent assay (ELISA), and the expressions of β-catenin and GSK-3β proteins related to Wnt/β-catenin signal pathway in hippocampus were measured by Western blot.Results:Compared with model group, the escape latency was shortened in the Huatan Quyu Decoction high-dosage group and Donepezil group on 7 and 14 days of administration ( P<0.05), and the times of crossing the platform increased in Huatan Quyu Decoction high-dosage group on 1 and 28 days of administration ( P<0.05). Compared with model group, the serum ACA level in Donepezil group, Huatan Quyu Decoction medium- and high-dosage groups decreased at day 1, 7, 14 and 28 after administration ( P<0.05). The serum Aβ level in Donepezil group, Huatan Quyu Decoction medium- and high-dosage groups decreased at 7, 14 and 28 days after administration ( P<0.05); On the 14th and 28th days after administration, the levels of ACA and Aβ in TCM low-dosage group decreased ( P<0.05). Compared with model group, the expression of β-catenin protein in hippocampus of Donepezil group and Huatan Quyu Decoction medium- and high-dosage groups increased ( P<0.05), while the expression of GSK-3β in hippocampus of Donepezil group and Huatan Quyu Decoction low-, medium- and high-dosage groups decreased ( P<0.01). Conclusion:Huatan Quyu Decoction can activate the Wnt/β-catenin signaling pathway, up-regulate the expression of β-catenin protein in hippocampal tissue of rats, inhibit the expression of GSK-3β, reduce the levels of ACA and Aβ in serum of rats, and improve the cognitive function of rats with vascular dementia.

ObjectiveTo investigate the clinical efficacy and possible mechanism of Erzhi Tiangui prescription on repeated implantation failure （RIF） of kidney deficiency syndrome. MethodSeventy patients with RIF of kidney deficiency syndrome who underwent natural cycle frozen-thawed embryo transfer （FET） in the Reproductive and Genetic Center of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine were enrolled and randomly divided into a treatment group （35 cases） and a control group （35 cases）. Patients in the treatment group took oral Erzhi Tiangui prescription from the third day of each menstrual cycle two months before the FET cycle and continued to take it until the day of transplantation from the third day of the menstrual cycle in the month of transplantation. Those in the control group did not accept traditional Chinese medicine （TCM）. In addition，10 patients who successfully achieved clinical pregnancy after the first natural cycle FET were screened from the reproductive medical record bank of this hospital and assigned to the normal group. Peripheral blood samples of patients in the three groups on the day of embryo transfer were collected from the specimen bank of the Reproductive and Genetic Center. Serum soluble programmed death molecule-1 （sPD-1），soluble programmed death molecule-ligand 1 （sPD-L1），transforming growth factor-β （TGF-β），interleukin-17 （IL-17）， and interleukin-10 （IL-10） levels were measured by enzyme-linked immunosorbent assay （ELISA）. The changes in kidney deficiency syndrome scores， the final biochemical pregnancy rates， clinical pregnancy rates， and embryo implantation rates of the treatment group and the control group before and after treatment were observed. ResultCompared with the normal group，the model group showed increased serum levels of sPD-1 and IL-17（r=0.347，P<0.05），decreased levels of IL-10 and TGF-β （P<0.01），and non-significant change in sPD-L1 level. Serum sPD-1 was positively correlated with IL-17 （P<0.05） and negatively correlated with IL-10（r=-0.521，P<0.01） and TGF-β（r=-0.457，P<0.01） in RIF patients with kidney deficiency syndrome. After TCM treatment，compared with the control group， the treatment group showed improved TCM syndrome score （P<0.05） and increased clinical pregnancy rate and embryo transfer rate（P<0.05），but there was no statistically significant difference in the biochemical pregnancy rate between the two groups. ConclusionAbnormal expression of sPD-1 in patients with RIF of kidney deficiency syndrome breaks the balance of T helper 17 （Th17）/regulatory T cell （Treg），which is not conducive to embryo implantation and pregnancy maintenance. Erzhi Tiangui prescription，a TCM for tonifying the kidney，can significantly improve the symptoms of kidney deficiency in patients with RIF of kidney deficiency syndrome，reduce the concentrations of sPD-1 and IL-17 in the peripheral serum，increase the levels of TGF-β and IL-10，regulate the peripheral Th17/Treg immune balance，and increase the implantation rate and clinical pregnancy rate，which has a high clinical value.

Objective:To explore the responsibilities of respiratory nurses in the management of chronic obstructive pulmonary disease (COPD) patient and the difficulties in disease management, so as to provide reference basis for formulating COPD management training strategies for respiratory nurses.Methods:Using phenomenological methodology, 14 nurses from the Department of Respiratory and Critical Care Medicine in the General Hospital of Ningxia Medical University and the First People′s Hospital of Yinchuan were interviewed in a personal semi-structured way from May to August 2021, and the data were sorted and analyzed according to Colaizzi 7-step analysis method.Results:Nurses′understanding of the responsibilities of COPD patient management could be summarized into five themes: dynamic monitoring and management of patients′ health, nursing decision-making of sudden changes in patients′ condition, implementation of patients′ out of hospital follow-up, promotion of improvement of patients′ self-management behavior, and cooperation among multidisciplinary team members. The difficult experience of nurses in the management of COPD patients abstracted five themes: lack of professional knowledge of COPD management, lack of clinical nursing decision-making authority, lack of human and financial support for follow-up, lack of communication skills with patients, and lack of multidisciplinary team formation in the hospital.Conclusions:Respiratory nurses have a clear understanding of the responsibilities of COPD patient management, but there are multiple difficulties in performing their responsibilities. We should pay attention to the responsibility positioning and difficulty support of nurses′ COPD management, and formulate targeted training strategies to promote the improvement of COPD nursing quality.

Objective:To prepare 68Ga-fibroblast activation protein inhibitor (FAPI)-04, and evaluate its biodistribution and imaging characteristics in animals and healthy volunteers, in order to investigate the clinical translation potential. Methods:68Ga-FAPI-04 was synthesized by a manual method and its radiolabeling yield, radiochemical purity, and stability ( in vivo and in vitro) were analyzed. ICR mice ( n=16) were scarified at 5, 30, 60 and 120 min postinjection of 68Ga-FAPI-04 (1.11 MBq) to measure radioactive counts in main organs. The dynamic mircoPET imaging was acquired for 60 min on 3 ICR mice, and tumor imaging capabilities were examined with nude mice bearing HepG2 tumors. Furthermore, 2 healthy volunteers (1 male with age of 64 years, 1 female with age of 56 years) were recruited for the investigation of probe biodistribution in humans. A serial whole-body dynamic PET/CT scan was performed immediately following injection. Results:68Ga-FAPI-04 was synthesized within 20 min with the radiochemical yield of (68.7±4.0)% (decay corrected). The radiochemical purities of 68Ga-FAPI-04 were over 99% and the products were stable for 180 min in vitro and for 90 min in blood. 68Ga-FAPI-04 was mainly cleared through urinary tracts, while other organs only showed mild tracer accumulation. MicroPET imaging showed high uptake of 68Ga-FAPI-04 in the tumor tissue of mice, and the ratio of tumor/liver was 2.14±0.01 (35 min). The PET/CT imaging results of healthy volunteers revealed 68Ga-FAPI-04 could be quickly cleared. Conclusion:68Ga-FAPI-04 has many advantages for PET imaging, such as easy labeling, good stability, quick clearance and low background signals in the liver, which can be used as an attractive PET tracer for detection hepatocellular carcinoma.

Objective: To retrospectively analyse the genetic characteristics, diagnosis, treatment and prognosis of special AT-rich binding protein 2 (SATB2)-associated syndrome. Methods: Clinical data of one case of SATB2-associated syndrome diagnosed in Children′s Hospital Affiliated to Zhengzhou University in January 2018, were collected including clinical test, treatment plan, follow-up outcomes. The clinical characteristics of SATB2-associated syndrome were analyzed, and literature review was conducted. Results: The female proband, eight-year-old, were admitted with the clinical manifestations including epilepsy seizures, delayed language development, sparse hair, long face, prominent forehead, long nose, lower eyelid cleft oblique, low ear, smooth philtrum, small mandible, sparse teeth arrangement, and lack of some teeth. The intelligence quotient score was 49. The brain magnetic resonance imaging showed myelinated dysplasia. Long-range video-electroencephalography showed spike-wave activity, slow spike-wave discharges in the bilateral middle and posterior temporal regions. The trio whole exome sequencing (trio WES) test showed that the proband carried a heterozygous nonsense mutation c.1300 C>T (p.Gln434Ter) in the SATB2 gene, and the muation was de novo comfirmed by pedigree analysis. Thirty-seven literatures relevant to SATB2-associated syndrome, from January 1989 to June 2019, were retrieved. Threre were 23 overseas literatures and one domestic report, including a total number of 158 cases. There were 49 missense mutations, 38 nonsense mutations, 32 frameshift mutations, seven splicing-site mutations, six translocation mutations, one insertion mutation, 22 gene-deletions and three gene-duplications. Among the 158 reported cases, 90 were male and 62 female, sex was not described in six cases. One hundred and fifty-eight (100.0%) patients had mental retardation, 44 (30.6%) with growth retardation, 107 (84.3%) with facial deformities, 70 (45.5%) with cleft palate, 135 (98.5%) with dental abnormalities, 66 (43.4%) with language retardation, 29 (20.0%) with epileptic seizures, and 50 (46.3%) with neuroimaging abnormalities. Conclusions The main clinical manifestations of SATB2-related syndromes are severe developmental retardation, low intelligence, delayed language development, language deficiency, high palatal arch and cleft palate, rare epilepsy seizures, dental anomalies and scant hair. The study identified a novel nonsense mutation c. 1300 C>T (p. Gln434Ter) in the SATB2 gene, which is responsible for the development of SATB2-associated syndrome.

Objective To identify current research hotspots, research trends and future trends of family physician research by means of literature review. Methods " Family physician" and " general practitioner" were used as the search words, to retrieve in CNKI database the literature on family physicians published during 2011 - 2018 using the method of subject retrieval, with related literature citations downloaded. The citespace software was used to analyze and generate the research institutions and their cooperative network, the keyword co-occurrence network and emergent word analysis. Information visualization was used to analyze the current research status of family physicians in China. Results A total of 1616 papers were retrieved, and 773 literatures were finalized as research samples with exclusion of those obviously irrelevant. The study found that studies in China focused on talent cultivation, service contract signature of family physicians, pattern of such contracts, and the construction of primary medical institutions. In terms of future research trends, the hotspots fell on " performance evaluation" , " incentive mechanism" , " talent cultivation" , " health management" , and " chronic disease management" by such physicians. Conclusions This paper used citespace software in a visual analysis of the research on family physicians in the recent eight years, so as to explore the research hotspots, research trends and future trends of such study in China.

Overexpressing of ATP-binding cassette (ABC) transporters is the essential cause of multidrug resistance (MDR), which is a significant hurdle to the success of chemotherapy in many cancers. Therefore, inhibiting the activity of ABC transporters may be a logical approach to circumvent MDR. Olmutinib is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), which has been approved in South Korea for advanced EGFR T790M-positive non-small cell lung cancer (NSCLC). Here, we found that olmutinib significantly increased the sensitivity of chemotherapy drug in ABCG2-overexpressing cells. Furthermore, olmutinib could also increase the retention of doxorubicin (DOX) and rhodamine 123 (Rho 123) in ABC transporter subfamily G member 2 (ABCG2)-overexpressing cells. In addition, olmutinib was found to stimulate ATPase activity and inhibit photolabeling of ABCG2 with [I]-iodoarylazidoprazosin (IAAP). However, olmutinib neither altered ABCG2 expression at protein and mRNA levels nor blocked EGFR, Her-2 downstream signaling of AKT and ERK. Importantly, olmutinib enhanced the efficacy of topotecan on the inhibition of S1-MI-80 cell xenograft growth. All the results suggest that olmutinib reverses ABCG2-mediated MDR by binding to ATP bind site of ABCG2 and increasing intracellular chemotherapeutic drug accumulation. Our findings encouraged to further clinical investigation on combination therapy of olmutinib with conventional chemotherapeutic drugs in ABCG2-overexpressing cancer patients.
