Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To investigate the current situation of community nursing needs of patients with middle and advanced Parkinson ′s disease, analyze the factors affecting the demand, and further explore the possible pathways of action between the factors, so as to provide the basis for formulating targeted community intervention measures in a more comprehensive way. Methods:A cross-sectional survey of 242 patients with middle and advanced Parkinson ′s disease from the Second Hospital Affiliated to the Army Medical University from November 2022 to January 2023 were selected by convenience sampling method, and the Community Care Need Scale, General Data Questionnaire, Readiness for Hospital Discharge Scale, Medical Coping Modes Questionnaire and the Self-management Effectiveness Questionnaire of Parkinson ′s disease patients were used. SPSS 26.0 was used to analyze the data, and investigated the relationship between readiness for hospital discharge, self-management efficacy, active coping styles, and community nursing needs. Results:A total of 234 valid questionnaires were collected, including 108 males and 126 females, aged 39-93 (67.25±8.93) years. The average score of all dimensions from high to low was: disease treatment dimension (4.16±0.42), daily care dimension (4.05±0.97), fall prevention dimension (4.04±0.80), extended care dimension (3.95±0.65), emotional support dimension (3.77±0.65) and self function (3.75±0.72). Univariate analysis indicated that there were statistically significant differences in community nursing needs scores among middle and advanced Parkinson ′s disease patients with different educational level and different family income ( F=5.11, 3.05, both P<0.05). Readiness for hospital discharge, self-management efficacy and positive coping style were negatively correlated with community nursing needs of patients with middle and advanced Parkinson′s disease ( r=-0.567, -0.412, -0.398, all P<0.01), and self-management efficacy and positive coping style played a partial mediating role between readiness for hospital discharge and community nursing needs. Conclusions:There is a wide range of community nursing needs that patients with middle and advanced Parkinson ′s disease, and patients with primary school and below, high school and above, and low family income are higher. It is suggested that the community disease management process should focus on this group of people. Medical institutions should help patients with middle and advanced Parkinson ′s disease improve their ability to manage the disease by improving discharge preparation services, so that they can smoothly transition from hospital to home, thereby reducing the needs for community nursing.

The study aims to observe the effects and explore the mechanisms of Buyang Huanwu Decoction and Astragali Radix-Angelicae Sinensis Radix combination in the treatment of the inflammatory response of mice with atherosclerosis(AS) via the Toll-like receptor 4(TLR4)/myeloid differentiation primary response protein 88(MyD88)/nuclear factor-κB(NF-κB) signaling pathway. Male ApoE~(-/-) mice were randomly assigned into a model group, a Buyang Huanwu Decoction group, an Astragali Radix-Angelicae Sinensis Radix combination group, and an atorvastatin group, and male C57BL/6J mice of the same weeks old were used as the control group. Other groups except the control group were given high-fat diets for 12 weeks to establish the AS model, and drugs were administrated by gavage. Aortic intimal hyperplasia thickness, blood lipid level, plasma inflammatory cytokine levels, M1/M2 macrophage markers, and expression levels of proteins in TLR4/MyD88/NF-κB pathway in the vessel wall were measured to evaluate the effects of drugs on AS lesions and inflammatory responses. The results showed that the AS model was successfully established with the ApoE~(-/-) mice fed with high-fat diets. Compared with the control group, the model group showed elevated plasma total cholesterol(TC), triglyceride(TG), and low-density lipoprotein cholesterol(LDL-c) levels(P<0.05), thickened intima(P<0.01), and increased plasma tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) levels(P<0.01). Moreover, the model group showed increased expression of vascular cell adhesion molecule-1(VCAM-1) and inducible nitric oxide synthase(iNOS)(P<0.01), inhibited expression of endothelial nitric oxide synthase(eNOS) and cluster of differentiation 206(CD206)(P<0.01), and up-regulated mRNA and protein levels of TLR4, MyD88, NF-κB inhibitor alpha(IκBα), and NF-κB in the vessel wall(P<0.05). Compared with the model group, Buyang Huanwu Decoction and Astragali Radix-Angelicae Sinensis Radix combination lowered the plasma TC and LDL-c levels(P<0.01), alleviated the intimal hyperplasia(P<0.01), and reduced the plasma TNF-α and IL-6 levels(P<0.05). Moreover, the two interventions promoted the expression of eNOS and CD206(P<0.05), inhibited the expression of VCAM-1 and iNOS(P<0.01), and down-regulated the mRNA and protein levels of TLR4, MyD88, IκBα, and NF-κB(P<0.05) in the vessel wall. This study indicated that Buyang Huanwu Decoction and Astragali Radix-Angelicae Sinensis Radix combination could delay the progression of AS, inhibit the polarization of vascular wall macrophages toward M1 type, and attenuate vascular inflammatory response by inhibiting the activation of TLR4/MyD88/NF-κB signaling pathway in the vascular wall. Astragali Radix and Angelicae Sinensis Radix were the main pharmacological substances in Buyang Huanwu Decoction for alleviating the AS vascular inflammatory response.

Objective:Human leukocyte antigen(HLA)B27 is a susceptibility allele of ankylosing spondylitis(AS),and HLA-B27 antigen typing is an important indicator for clinical diagnosis of AS,but current typing methods such as sequence specific primer polymerase chain reaction(PCR-SSP)still possess limitation.Therefore,this study aims to analyze the correlation between B27 subtypes and susceptibility to AS in Hunan Province by applying high-resolution polymerase chain reaction-sequence-based typing(PCR-SBT). Methods:Peripheral blood of 116 patients with suspected AS(suspected AS group)and 121 healthy volunteers(control group)admitted to the Second Xiangya Hospital from January 2020 to December 2020 were collected for HLA-B genotyping by PCR-SBT.Among the patients in the suspected AS group,23 patients were finally diagnosed with AS(confirmed AS group),and the remaining 93 undiagnosed patients served as the non-confirmed AS group.PCR-SBT and PCR-SSP were used to detect HLA-B27 typing in 116 patients with suspected AS,and the results of the 2 methods were compared. Results:The HLA-B27 allele frequency in the suspected AS group was significantly higher than that in the control group[11.63%vs 2.48%;P<0.001,odds ratio(OR)=5.18,95%confidence interval(CI)2.097 to 12.795].B*27:04,B*27:05,B*27:06,and B*27:07 were detected in the suspected AS group and the control group.The frequency of the B*27:04 allele in the suspected AS group was significantly higher than that in the control group(9.48%vs 1.24%;P<0.001,OR=8.346,95%CI 2.463 to 28.282).The positive rate of B27 in the suspected AS group and the confirmed AS group(B27+/+ and B27+/-)was significantly higher than that in the control group(χ2=16.579,P<0.001;χ2=94.582,P<0.001,respectively).Among the confirmed AS group,21 were HLA-B27 carriers,and the B27 positive rate in the confirmed AS group was 91.3%.PCR-SBT could achieve high resolution typing of the HLA-B gene locus,with higher sensitivity,specificity,positive predictive value,negative predictive value,and accuracy than PCR-SSP. Conclusion:PCR-SBT typing analysis shows a strong correlation between HLA-B * 27:04 and AS in Hunan province.The PCR-SBT method can be used as the preferred option for the auxiliary diagnosis of clinical AS.

OBJECTIVE: To investigate the expression and clinical significance of soluble Fas (sFas) and sFasL in patients with secondary hemophagocytic lymphohistiocytosis (sHLH). METHODS: From September 2015 to December 2020, 86 sHLH patients who met the HLH2004 diagnostic criteria were collected. They were divided into 55 cases in the MAHLH group and 31 cases in the NonMAHLH group according to the etiology. Thirty healthy persons were chosen as the normal control group, and 20 patients with systemic lupus erythematosus (SLE) were chosen as the disease control group. The expression levels of sFas and sFasL in the serum of patients with each group were detected by ELISA, and the clinical data were collected for statistical analysis. The significance of sFas and sFasL in sHLH was analyzed by ROC curve. RESULTS: Serum levels of sFas and sFasL in patients with newly diagnosed sHLH were significantly higher than those in disease control group and normal control group (P<0.01). The levels of sFas and sFasL in MAHLH group were significantly higher than those in nonMAHLH (infection related HLH and autoimmune disease related HLH) group (P<0.01). The serum levels of sFas and sFasL in 17 newly treated patients with sHLH (17/86) after treatment were significantly lower than those before treatment (P<0.01). The serum sFas level in newly diagnosed sHLH patients was positively correlated with SF(r=0.35), sCD25(r=0.79) and sFasL(r=0.73). The serum sFasL level was positively correlated with SF(r=0.39), sCD25(r=0.64) and sFas(r=0.73). Compared with the NonMAHLH group, the area under the ROC curve was 0.707 (95% CI: 0.593-0.821) (P=0.0015). The optimal critical value for diagnosing MAHLH by sFas level was 12 743 pg/ml, and the sensitivity and specificity were 70.9% and 71% respectively. Compared with the NonMAHLH group, the area under the ROC curve was 0.765(95% CI: 0.659-0.87)(P<0.01). The median OS time of sFas high expression group (≥16798.5 pg/ml) and sFasL high expression group (≥4 785 pg/ml) was significantly shorter than that of the low expression group (P<0.001). CONCLUSION Serum levels of sFas and sFasL can be used for the early diagnosis and differential diagnosis of sHLH disease, and are the factor related to the poor prognosis of sHLH.

Over the past half-century,the climate change,along with population growth,worsens the intensity and frequency of sand storms in China,and the environmental and health problems have become increasingly prominent.Sand and dust particles not only possess their own toxicity but also carry numerous pathogenic microorganisms and heavy metals.This can lead to high concentrations of local dust pollution,causing significant harm to the air environment and the health of residents in downwind areas during long-distance transportation sand and dust.Based on a comprehensive literature review on the health effects of dust storms,this paper aims to summarize the impact of various pathogenic factors presenting in dust storms on human health and the underlying mechanisms to provide a scientific foundation for the development of more effective control measures.In the future,amidst the backdrop of climate change,it is crucial to prioritize the research and analysis of dust source regions and dust control strategies in northern China.Additionally,there is a need to enhance the technology for simulating sand and dust environments in experiments,and to adopt a multidisciplinary approach to investigate the medical and toxicological aspects of sand and dust weather.

We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia (GTN). In this trial (NCT01823315), 276 patients were analyzed. Patients were allocated to three initiated regimens: single-course methotrexate (MTX), single-course MTX + dactinomycin (ACTD), and multi-course MTX (control arm). The primary endpoint was the complete remission (CR) rate by initial drug(s). The primary CR rate was 64.4% with multi-course MTX in the control arm. For the single-course MTX arm, the CR rate was 35.8% by one course; it increased to 59.3% after subsequent multi-course MTX, with non-inferiority to the control (difference -5.1%,95% confidence interval (CI) -19.4% to 9.2%, P = 0.014). After further treatment with multi-course ACTD, the CR rate (93.3%) was similar to that of the control (95.2%, P = 0.577). For the single-course MTX + ACTD arm, the CR rate was 46.7% by one course, which increased to 89.1% after subsequent multi-course, with non-inferiority (difference 24.7%, 95% CI 12.8%-36.6%, P < 0.001) to the control. It was similar to the CR rate by MTX and further ACTD in the control arm (89.1% vs. 95.2%, P =0.135). Four patients experienced recurrence, with no death, during the 2-year follow-up. We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN.

Objective: To investigate the relationship between nutritional risk status and clinical outcome in children with tuberculous meningitis (TBM). Methods: The clinical data (basic information, clinical symptoms and laboratory test results) of 112 patients with TBM, who were admitted to Department of Pediatric Infectious Diseases of West China Second Hospital of Sichuan University,from January 2013 to December 2020 were retrospectively analyzed. The patients were divided into the nutritional risk group and the non-nutritional risk group according to the assessment of the nutritional risk by the STRONGkids Scale. The variables of basic information, clinical symptoms and laboratory test measurements etc. were compared between the two groups by using Student t test, Rank sum test or Chi-square test. Multivariate Logistic regression analysis were used to analyze nutritional risk factors. Results: Among 112 patient with TBM, 55 were males and 57 females. There were 62 cases in the nutritional risk group and 50 cases in the non-nutritional risk group. The proportion of cases with nutritional risk was 55.4% (62/112). Patients in the nutritional risk who lived in rural areas, had symptoms of brain nerve damage, convulsions, emaciation and anorexia, with a diagnosis time of ≥21 days, and the level of cerebrospinal fluid (CSF) protein were all higher than those in the non-nutritional risk group ((50 cases (80.6%) vs. 32 cases (64.0%), 20 cases (32.3%) vs.8 cases (16.0%), 33 cases (53.2%) vs. 15 cases (30.0%), 30 cases (48.4%) vs. 2 cases (4.0%), 59 cases (95.2%) vs. 1 case (2.0%),41 cases (66.1%) vs.18 cases (36.0%), 1 406 (1 079, 2 068) vs. 929 (683, 1 208) mg/L, χ²=3.91, 3.90, 6.10, 26.72, 98.58, 10.08, Z=4.35, all P<0.05). The levels of serum albumin,hemoglobin,lymphocyte count, white blood cell count, and CSF glucose were significantly lower in patients with nutritional risk ((36±5) vs. (41±4) g/L, (110±17) vs. (122±14) g/L, 1.4 (1.0, 2.0)vs. 2.3 (1.6, 3.8)×10⁹/L, 7.8 (6.3, 10.0)×10⁹ vs. 10.0 (8.3, 12.8)×10⁹/L, 1.0 (0.8, 1.6) vs. 2.1 (1.3, 2.5) mmol/L, t=-6.15, -4.22, Z=-4.86, -3.92, -4.16, all P<0.05).Increased levels of serum albumin (OR=0.812, 95%CI:0.705-0.935, P=0.004) and lymphocyte count (OR=0.609, 95%CI:0.383-0.970, P=0.037) may reduce the nutritional risk of children with TBM; while convulsions (OR=3.853, 95%CI:1.116-13.308, P=0.033) and increased level of CSF protein (OR=1.001,95%CI:1.000-1.002, P=0.015) may increase the nutritional risk of children with TBM. Similarly, the rate of complications and drug-induced liver injury was higher in the nutritional risk group (47 cases (75.8%) vs. 15 cases(30.0%), 31 cases (50.0%) vs.8 cases (16.0%), χ²=23.50, 14.10, all P<0.05). Moreover, the length of hospital stay was also longer in the nutritional risk group ((27±13) vs. (18±7) d, t=4.38, P<0.05). Conclusions: Children with TBM have a high incidence of nutritional risk. Convulsive, the level of serum albumin, the level of lymphocyte count and CSF protein may affect the nutritional risk of children with TBM. The nutritional risk group has a high incidence of complications and heavy economic burden.It is necessary to carry out nutritional screening and nutritional support for children with TBM as early as possible.

Objective: Dysregulation of gene expression through epigenetic mechanisms may have a vital role in the pathogenesis of schizophrenia (SZ). In this study, we investigated the association of altered methylation patterns with SZ symptoms and early trauma in patients and healthy controls. Methods: The present study was conducted to identify methylation changes in CpG sites in peripheral blood associated with recent-onset (RO) psychosis using methylome-wide analysis. Lifestyle factors, such as smoking, alcohol, exercise, and diet, were controlled. Results: We identified 2,912 differentially methylated CpG sites in patients with RO psychosis compared to controls. Most of the genes associated with the top 20 differentially methylated sites had not been reported in previous methylation studies and were involved in apoptosis, autophagy, axonal growth, neuroinflammation, protein folding, etc. The top 15 significantly enriched Kyoto Encyclopedia of Genes and Genomes pathways included the oxytocin signaling pathway, long-term depression pathway, axon guidance, endometrial cancer, long-term potentiation, mitogen-activated protein kinase signaling pathway, and glutamatergic pathway, among others. In the patient group, significant associations of novel methylated genes with early trauma and psychopathology were observed. Conclusion Our results suggest an association of differential DNA methylation with the pathophysiology of psychosis and early trauma. Blood DNA methylation signatures show promise as biomarkers of future psychosis.

Objective:To analyze the long-term trend of viral hepatitis mortality in Jing’an District of Shanghai， and to provide a reference for viral hepatitis prevention and control. Methods:Mortality rate， standard mortality rate， PYLL and potential years of life lost rate （PYLL‰） of viral hepatitis in Jing’an district of Shanghai from 1976 to 2015 were calculated. The annual percent change （APC） of the mortality and PYLL‰ were analyzed by Joinpoint regression analysis. Results:From 1976 to 2015， there were 1 342 viral hepatitis death cases， including 832 males and 510 females. The average crude mortality rate was 8.31/100 000， and the average age-standardized mortality rate was 5.45/100 000. Among the deaths of viral hepatitis， men had a higher mortality rate， age-standardized mortality rate and PYLL% than women （χ2_Pearson=107.34， 112.93， 39.15， all P<0.01）， men were mainly in the age group of 35-64 years （accounted for 62.62%）， while women were mainly in the age group of 65 years and above （accounted for 55.49 %）， and the average death age of men was earlier than that of women （by rank-sum test： Z=-8.879，P<0.01）. After 1990 （except in 2002）， hepatitis B was the main cause of deaths from viral hepatitis， accounting for 75.00%-100%， and the proportion of other and unclassified cases gradually decreased. Overall， the mortality rate of viral hepatitis declined significantly during 1976-2015 （APC=-2.0%，P<0.05）， with the turning point in 2002. The mortality rate of viral hepatitis declined significantly from 2002 to 2015 （APC=-8.1%，P<0.05）. The overall PYLL‰ of viral hepatitis declined significantly during 1976-2015 （APC=-3.7%，P<0.05）， with the turning point in 1992. After 1992， the PYLL‰ of viral hepatitis declined significantly during 1992-2015 （APC=-6.5%，P<0.05）. Conclusion:There has been a significant decline trend of viral hepatitis in the mortality rate in Jing’an District of Shanghai from 2002 to 2015， with hepatitis B as the main cause of death.
