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: To evaluate the safety and efficacy of thiotepa (TT)-containing conditioning regimens for allogeneic hematopoietic stem cell transplantation (HSCT) in children with inborn errors of immunity (IEI). METHODS: Clinical data of 22 children with IEI who underwent HSCT were retrospectively reviewed. Survival after HSCT was estimated using the Kaplan-Meier method. RESULTS: Nine patients received a traditional conditioning regimen (fludarabine + busulfan + cyclophosphamide/etoposide) and underwent peripheral blood stem cell transplantation (PBSCT). Thirteen patients received a TT-containing modified conditioning regimen (TT + fludarabine + busulfan + cyclophosphamide), including seven PBSCT and six umbilical cord blood transplantation (UCBT) cases. Successful engraftment with complete donor chimerism was achieved in all patients. Acute graft-versus-host disease occurred in 12 patients (one with grade III and the remaining with grade I-II). Chronic graft-versus-host disease occurred in one patient. The incidence of EB viremia in UCBT patients was lower than that in PBSCT patients (P<0.05). Over a median follow-up of 36.0 months, one death occurred. The 3-year overall survival (OS) rate was 100% for the modified regimen and 88.9% ± 10.5% for the traditional regimen (P=0.229). When comparing transplantation types, the 3-year OS rates were 100% for UCBT and 93.8% ± 6.1% for PBSCT (P>0.05), and the 3-year event-free survival rates were 100% and 87.1% ± 8.6%, respectively (P>0.05). CONCLUSIONS TT-containing conditioning for allogeneic HSCT in children with IEI is safe and effective. Both UCBT and PBSCT may achieve high success rates.

OBJECTIVE: To evaluate the efficacy and safety of denosumab in the treatment of prostate cancer with bone metastases. METHODS: Relevant studies were retrieved from PubMed, EMBASE, Cochrane, Web of Science, Sinomed , CNKI and Wanfang databases. The Cochrane risk-of-bias assessment tool was used to evaluate the quality of included studies, and relevant data were extracted. meta-analysis was performed using RevMan 5.4 and RStudio software, and forest plots were generated. RESULTS: Six randomized controlled trials (RCTs) were included. Compared with the control group, denosumab significantly reduced the risk of skeletal-related events (HR=0.78, 95% CI: 0.62-0.93). In terms of safety, denosumab did not increase the risk of total adverse events, severe adverse events and the adverse events higher than CTC grade 3. CONCLUSION Denosumab can delay the time to first skeletal-related event with good safety. However, due to the limitations of this study, further high-quality, large-sample, multicenter RCTs are needed to confirm these findings.

Ovarian tumor (OT) is the most lethal form of gynecologic malignancy, with minimal improvements in patient outcomes over the past several decades. Metastasis is the leading cause of ovarian cancer-related deaths, yet the underlying mechanisms remain poorly understood. Psychological stress is known to activate the glucocorticoid receptor (NR3C1), a factor associated with poor prognosis in OT patients. However, the precise mechanisms linking NR3C1 signaling and metastasis have yet to be fully elucidated. In this study, we demonstrate that chronic restraint stress accelerates epithelial-mesenchymal transition (EMT) and metastasis in OT through an NR3C1-dependent mechanism involving nuclear protein 1 (NUPR1). Mechanistically, NR3C1 directly regulates the transcription of NUPR1, which in turn increases the expression of snail family transcriptional repressor 2 (SNAI2), a key driver of EMT. Clinically, elevated NR3C1 positively correlates with NUPR1 expression in OT patients, and both are positively associated with poorer prognosis. Overall, our study identified the NR3C1/NUPR1 axis as a critical regulatory pathway in psychological stress-induced OT metastasis, suggesting a potential therapeutic target for intervention in OT metastasis.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Objective To explore the mediating effect of maternal childbirth self-efficacy between reproductive health literacy during pregnancy and expected mode of delivery,in order to provide a reference for obstetric care providers to carry out scientific and reasonable childbirth decision support interventions.Methods A questionnaire survey was conducted among pregnant women in late pregnancy seeing doctors in Obstetric Clinic of Obstetrics and Gynecology Hospital,Fudan University from Oct 2020 to Feb 2021 using convenience sampling.A general information questionnaire,the Reproductive Health Literacy Scale,and Childbirth Self-efficacy Scale were used in the survey.Linear regression and Logistic regression analyses were used to assess the associations between reproductive health literacy during pregnancy and childbirth self-efficacy and expected mode of delivery,respectively,and to assess the significance of the mediating effect of childbirth self-efficacy between productive health literacy during pregnancy and expected mode of delivery.The MacKinnon's product-of-coefficients method was used to assess the mediating effect of maternal childbirth self-efficacy.Results A total of 343 participants were included in the study.Regression analysis results of factors influencing expected mode of delivery showed that reproductive health literacy during pregnancy(c'=1.644,95%CI:2.223-12.059)and childbirth self-efficacy(β=2.211,95%CI:6.300-13.215)were associated with expected mode of delivery(P<0.001);childbirth self-efficacy was significantly and positively associated with reproductive health literacy during pregnancy(β=1.280,95%CI:0.102-0.165,P<0.01).Childbirth self-efficacy was a mediating variable for health literacy during pregnancy and expected mode of delivery with an effect size of 24.8%.Conclusion Childbirth self-efficacy mediated the association between reproductive health literacy during pregnancy and expected mode of delivery.Obstetric care providers should focus on strengthening maternal care and childbirth education,improving pregnant women's childbirth self-efficacy and reproductive health literacy during pregnancy,thereby enabling women to make scientific decisions on expected mode of delivery in order to promote normal childbirth.

Objective To observe the efficacy of Chinese medicine in the treatment of pregnancy complicated with thalassemia and to investigate its influence on pregnancy outcomes.Methods A retrospective cohort study was carried out in 175 pregnant women complicated with thalassemia who met the inclusion criteria.According to the treatment methods,the patients were divided into Chinese medicine group(105 cases),iron supplementation group(41 cases)and untreated group(29 cases).The changes of hematological indicators and pregnancy outcomes in the second and third trimesters of pregnancy were compared among the three groups.The Chinese medicine group was further divided into three subgroups:56 cases in the Chinese patent medicine group,20 cases in the single Chinese medicine group and 29 cases in the Chinese herbal compound group.The changes of hematological indexes in the second and third trimesters of pregnancy in the three subgroups were compared.Moreover,the normative management of pregnant women with thalassemia during pregnancy was explored.Results(1)The concentration of hemoglobin(Hb)in the third trimester of the Chinese medicine group was(2.28±7.27)g/L higher than that in the second trimester,and the curative effect of Chinese medicine group was superior to that in the iron supplementation group and the untreated group(P＜0.05).The Hb concentration in the Chinese medicine group before delivery was(12.17±10.81)g/L higher than that in the second trimester,and the increase in the Chinese medicine group was more significantly than that in the other two groups(P＜0.05).(2)The level of serum ferritin(FER)in the third trimester of the three groups was lower than that in the second trimester,and the decrease of FER level in the iron supplementation group was less significantly than that in the other two groups(P＜0.05).(3)The Hb concentration in the third trimester of the single Chinese medicine group and the Chinese herbal compound group increased by(4.50±4.66),(3.62±8.77)g/L respectively compared with that in the second trimester,and the increase in the above two groups was more significantly than that in the Chinese patent medicine group(P＜0.05).(4)There was no significant difference in pregnancy outcomes among the three groups of pregnant women with thalassemia(P＞0.05).(5)Only 52.0％(91/175)of pregnant women with thalassemia underwent three or more blood routine tests after 20-24 weeks of pregnancy,34.3％(60/175)of pregnant women failed in re-examining the FER levels,and 21.2％(37/175)of pregnant women had no standardized iron supplementation.Conclusion Chinese medicine therapy is effective on improving anemia in pregnant women with thalassemia.Chinese herbal compound and single Chinese medicinal are more effective than Chinese patent medicine,and have not increased the risk of adverse pregnancy outcomes.Oral administration of iron can increase the iron reserve of pregnant women with thalassemia,but its effect on improving anemia is not as good as that of Chinese medicine.Attention should be got to the monitoring of anemia and iron metabolism indicators as well as the standardized use of iron supplements and Chinese patent medicines in pregnant women with thalassemia.

Objective To investigate the effects and mechanism of β2 adrenergic receptors(ADRB2)in ferroptosis and autophagy induced by erastin(Era)in prostate cancer.Methods PC-3 cells were infected with lentivirus or control and set to sh-NC group(normal culture),sh-NC+Era group(10 μmol/L Era treatment for 24 h),sh-ADRB2 group(normal culture),and sh-ADRB2+Era group(10 μmol/L Era treatment for 24 h).The viability of the cells treated with Era and ferrostatin-1(Fer-1)was measured by CCK-8 assay.The cell morphology was analyzed by transmission electron microscopy.The malondialdehyde(MDA)content was measured by the Lipid Oxidation Detection Kit and the iron level by Iron Colorimetric Assay.Western blotting was used to detect the expressions of cystine-glutamate exchanger(XCT),ferritin heavy chain 1(FTH1),glutathione peroxidase 4(GPX4),p62,LC3,JNK,c-Jun,and p-c-Jun.PC-3 cells with ADRB2 knockdown were injected into nude mice to construct a xenograft model and then treated with Era.The animals were divided into sh-NC group,sh-NC+Era group,sh-ADRB2 group,and sh-ADRB2+Era group,with 4 mice in each group.The tumor volumes were recorded every other day and the final tumor weight was measured at study termination.The expressions of ADRB2,JNK,c-Jun,and p-c-Jun were detected by immunohistochemistry(IHC).Results The viability of PC-3 cells decreased after Era treatment(P<0.01)and recovered after Fer-1 treatment(P<0.01).Morphological changes of ferroptosis and autophagy were observed in Era-treated cells,and MDA and iron ion contents up-regulated(P<0.05 or P<0.01).Knockdown of ADRB2 and Era treatment further inhibited PC-3 cell viability(P<0.05),and MDA and iron ion contents up-regulated(P<0.01).The expressions of ferroptosis-related proteins FTH1,XCT,GPX4,and LC3 down-regulated(P<0.05 or P<0.05),p62 and JNK pathway-related proteins JNK,c-Jun,and p-c-Jun were up-regulated(P<0.01).After JNK inhibitor treatment,the expressions of FTH1,XCT,and LC3 increased,and p62 decreased(P<0.01).In the PC-3 xenograft model,tumor volume in sh-ADRB2+Era group was significantly smaller than those in sh-NC+Era group and sh-ADBR2 group(P<0.05 or P<0.01).IHC showed that compared with sh-NC group,ADRB2 protein expression level was down-regulated in sh-ADRB2 group(P<0.05),while JNK,c-Jun,and p-c-Jun protein expression levels were elevated(P<0.01).Compared with sh-NC+Era group,the ADRB2 protein expression level in sh-ADRB2+Era group was down-regulated,while JNK,c-Jun,and p-c-Jun protein expression levels were up-regulated(P<0.05).Conclusion ADRB2 regulated ferroptosis and autophagy induced by Era via JNK/c-Jun pathway in prostate cancer.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive dysfunction and behavioral impairment, and there is a lack of effective drugs to treat AD clinically. Existing medications for the treatment of AD, such as Tacrine, Donepezil, Rivastigmine, and Aducanumab, only serve to delay symptoms and but not cure disease. To add insult to injury, these medications are associated with very serious adverse effects. Therefore, it is urgent to explore effective therapeutic drugs for AD. Recently, studies have shown that a variety of enzyme inhibitors, such as cholinesterase inhibitors, monoamine oxidase (MAO)inhibitors, secretase inhibitors, can ameliorate cholinergic system dysfunction, Aβ production and deposition, Tau protein hyperphosphorylation, oxidative stress damage, and the decline of synaptic plasticity, thereby improving AD symptoms and cognitive function. Some plant extracts from natural sources, such as Umbelliferone, Aaptamine, Medha Plus, have the ability to inhibit cholinesterase activity and act to improve learning and cognition. Isochromanone derivatives incorporating the donepezil pharmacophore bind to the catalytic active site (CAS) and peripheral anionic site (PAS) sites of acetylcholinesterase (AChE), which can inhibit AChE activity and ameliorate cholinergic system disorders. A compound called Rosmarinic acid which is found in the Lamiaceae can inhibit monoamine oxidase, increase monoamine levels in the brain, and reduce Aβ deposition. Compounds obtained by hybridization of coumarin derivatives and hydroxypyridinones can inhibit MAO-B activity and attenuate oxidative stress damage. Quinoline derivatives which inhibit the activation of AChE and MAO-B can reduce Aβ burden and promote learning and memory of mice. The compound derived from the combination of propargyl and tacrine retains the inhibitory capacity of tacrine towards cholinesterase, and also inhibits the activity of MAO by binding to the FAD cofactor of monoamine oxidase. A series of hybrids, obtained by an amide linker of chromone in combine with the benzylpiperidine moieties of donepezil, have a favorable safety profile of both cholinesterase and monoamine oxidase inhibitory activity. Single domain antibodies (such as AAV-VHH) targeted the inhibition of BACE1 can reduce Aβ production and deposition as well as the levels of inflammatory cells, which ultimately improve synaptic plasticity. 3-O-trans-p-coumaroyl maslinic acid from the extract of Ligustrum lucidum can specifically inhibit the activity of γ-secretase, thereby rescuing the long-term potentiation and enhancing synaptic plasticity in APP/PS1 mice. Inhibiting γ-secretase activity which leads to the decline of inflammatory factors (such as IFN-γ, IL-8) not only directly improves the pathology of AD, but also reduces Aβ production. Melatonin reduces the transcriptional expression of GSK-3β mRNA, thereby decreasing the levels of GSK-3β and reducing the phosphorylation induced by GSK-3β. Hydrogen sulfide can inhibitGSK-3β activity via sulfhydration of the Cys218 site of GSK-3β, resulting in the suppression of Tau protein hyperphosphorylation, which ameliorate the motor deficits and cognitive impairment in mice with AD. This article reviews enzyme inhibitors and conformational optimization of enzyme inhibitors targeting the regulation of cholinesterase, monoamine oxidase, secretase, and GSK-3β. We are hoping to provide a comprehensive overview of drug development in the enzyme inhibitors, which may be useful in treating AD.

Objective To evaluate the molluscicidal effect and cost of spraying molluscicides with drones against Oncomelania hupensis snails in marshland and lake areas, so as to provide new insights into field snail control in China. Methods A marshland and lake setting measuring approximately 12 000 m² was selected in Wanzhi District, Wuhu City on June 2023 as the test field, and assigned to four groups, of 3 000 m² in each group. Environmental cleaning was not conducted in groups A or B, which were given 5% niclosamide ethanolamine salt granules sprayed with knapsack-type sprayers and drones at a dose of 40 g/m², and environmental cleaning was conducted in groups C and D, which were given 5% niclosamide ethanolamine salt granules sprayed with drones and knapsack-type sprayers at a dose of 40 g/m², respectively. O. hupensis snails were surveyed before chemical treatment and 1, 3, 5, 7, 14 days post-treatment. The uniformity of chemicals was determined on the day of treatment, and the snail mortality, corrected snail mortality and density of living snails were calculated and compared among groups. The cost of molluscicides, labor fees of environmental cleaning and chemical treatment and cost of equipment were calculated, and the cost for a 1% reduction in the mean density of living snails was calculated 14 days post-treatment. Results The mean densities of living snails and mortality rates of snails were 1.82 to 2.85 snails/0.1 m² and 1.41% to 2.94% in groups A, B, C and D before chemical treatment, and the mortality and corrected mortality of snails were 55.75%, 49.32%, 85.94% and 87.50%, and 55.00%, 48.47%, 85.70% and 87.29% in groups A, B, C and D 14 days post-treatment. There was a significant difference in the mortality of snails among the four groups 14 days post-treatment (χ² = 38.735, P < 0.005), and there was a higher snail mortality in Group D than in Group A (χ² = 16.876, P < 0.005), and higher in Group C than in Group B (χ² = 20.508, P < 0.005). The density of living snails reduced by 55.00%, 43.94%, 90.43% and 87.14% 14 days post-treatment relative to pre-treatment in groups A, B, C and D, respectively. The test for uniformity of chemicals showed that the mean dose of molluscicides were 57.34, 55.21, 40.19 g/m² and 32.37 g/m² in groups A, B, C and D, respectively, and the minimal standard deviation (7.07) and coefficient of variation (0.18) of mean doses were seen in Group C. The costs for chemical treatment were 0.33 Yuan in groups A and B and 1.53 Yuan in groups C and D, respectively. The costs for a 1% reduction in the mean density of living snails were 17.82, 22.47, 50.73 Yuan and 52.56 Yuan in groups A, B, C, and D 14 days post-treatment, respectively. Conclusions The molluscicidal effect and cost of spraying 5% niclosamide ethanolamine salt granules with drones are comparable to manual spraying, and chemical treatment with drones are high in uniformity of molluscicides, time- and labor-saving, and feasible for applications in complex environments, which deserves widespread applications in the field of snail control.
