ObjectiveTo observe the clinical efficacy of the stasis-dispelling and detoxifying therapy in endometriosis （EMs） patients with the syndrome of kidney deficiency and blood stasis and the effects of this therapy on the expression levels of proteins related to the c-Jun N-terminal kinase （JNK） signaling pathway. MethodsA total of 72 patients with EMs due to kidney deficiency and blood stasis who met the criteria at the Integrated Traditional Chinese and Western Medicine Center for Reproduction and Genetics of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from March 2024 to February 2025 were selected and randomized into a treatment group and a control group， with 36 patients in each group. Another 36 patients undergoing in vitro fertilization-embryo transfer （IVF-ET） due to male factors alone were selected as the blank group. The treatment group took the Zishen Quyu Jiedu formula orally， while the control group and the blank group took placebos. The treatment course encompassed the cycle before ovarian stimulation and the oocyte retrieval cycle. The TCM syndrome score of kidney deficiency and blood stasis， as well as the serum level of cancer antigen 125 （CA125）， were evaluated at the time of enrollment （before treatment） and on the trigger day （after treatment）. Serum levels of sex hormones were measured on day 2 of the menstrual cycle. On the trigger day， the duration and dosage of gonadotropin （Gn） administration and the serum levels of hormones on the day of human chorionic gonadotropin （HCG） injection were assessed. Embryo outcomes were evaluated 3 days after oocyte retrieval， and clinical pregnancy rates were assessed 28 days after embryo transfer. The baseline data of three groups were observed. The TCM syndrome scores and serum CA125 levels before and after treatment were compared between the treatment and control groups. The baseline endocrine levels， Gn days， Gn dosage， hormone levels on the day of HCG administration， number of oocytes retrieved， number of 2 pronucleus （2PN） fertilizations， number of available embryos， high-quality embryo rate， and clinical pregnancy rate were also assessed in all three groups. Six patients from each group were selected for determination of the protein levels of JNK， c-Jun， and nuclear receptor subfamily 4 group A member 2 （NR4A2） in ovarian granulosa cells （GCs） on the day of oocyte retrieval by Western blot. Results（1） There were no statistically significant differences in the baseline data among three groups， indicating comparability. （2） Compared with the baseline within the same group， the treatment group showed a decrease in the syndrome score of kidney deficiency and blood stasis after treatment. After treatment， serum CA125 levels decreased in both groups （P<0.05）， with a more substantial reduction in the treatment group， resulting in a difference between the two groups （P<0.05）. （3） There were no significant differences among three groups in terms of baseline serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， and progesterone （P）， as well as the duration and dosage of Gn administration and the serum levels of LH， E₂， and P on the day of HCG administration. （4） For embryo outcomes， the number of oocytes retrieved， 2PN fertilizations， available embryos， and high-quality embryo rates in the treatment group and the blank group were higher than those in the control group （P<0.05）， and the treatment group and the blank group had similar 2PN fertilizations. （5） There were differences in clinical pregnancy rate among three groups （P<0.05）， and the treatment group had higher pregnancy rate than the control and blank groups. （6） The protein levels of JNK， c-Jun， and NR4A2 in the GCs of the treatment group were lower than those in the control group （P<0.01） and close to those in the blank group （P<0.01）. （7） No obvious adverse reactions were observed in any of the subjects during the clinical observation process. ConclusionZishen Quyu Jiedu formula can ameliorate the clinical symptoms of patients with EMs due to kidney deficiency and blood stasis， reduce the serum CA125 level， increase the number of oocytes retrieved， 2PN fertilizations， available embryos， and high-quality embryo rate， and improve pregnancy outcomes. The mechanism may involve downregulating the levels of JNK， c-Jun， and NR4A2 to reduce the apoptosis of ovarian GCs and improve the ovarian function in the patients.

Objective:To investigate the prevalence and mortality of dementia and assess the impact of geriatric syndromes (GS) on the risk for dementia and death in elderly population in Beijing.Methods:A cross-sectional survey was conducted in the elderly population aged ≥65 years and selected by a multi-stage sampling in Beijing during 2013-2015. Cognitive function was screened using the Chinese Revised Version of the Mini-Mental State Examination (MMSE). Then, neurological examination and psychiatric assessment were performed for those with the MMSE score lower than the cut-off value. The information about GS prevalence was also collected. The study also collected death records for all individuals from baseline until December 31, 2019. Based on the age and gender distribution from Beijing data of the 2010 Six th National Population Census, the dementia prevalence in the study population was directly standardized. Logistic regression analysis was used to evaluate the association of different forms of dementia with GS, and Cox proportional hazards regression model was used to estimate the hazard ratio ( HR) and 95% CI of death. Results:During 2013-2015, a total of 2 935 individuals completed dementia assessments, of which 167 were diagnosed with dementia. The standardized prevalence of dementia was 5.9% (95% CI: 5.0%-17.4%). The individuals with Alzheimer's disease (AD) and vascular dementia (VaD) accounted for 58.7% and 28.1% of total individuals with dementia, respectively. Aging, lower education level, urinary incontinence, and fall were risk factors for AD, while disability of activity of daily life dependence, hypertension, and stroke were found to be risk factors for VaD. After a median follow-up of 5.44 person-years, 399 deaths were recorded. The 5-year mortality risk was 2.87 (95% CI: 1.92-4.17) times and 4.93 (95% CI: 3.23-7.53) times higher for the elderly individuals with AD and VaD, respectively, compared to non-demented individuals. After adjusting for demographic, GS, and cardiovascular risk factors, the mortality risk in the elderly individuals with AD showed no significant difference compared with non-demented individuals ( HR=1.32, 95% CI: 0.89-1.97), while the mortality risk in those with VaD was 2.46 (95% CI: 1.49-4.05) times higher than that in non-demented individuals. Conclusions:The prevalence of dementia in Beijing increased significantly in the context of population aging, especially the prevalence of AD. The presence of GS increased the risks for AD and VaD, as well as the risk for death. Close attention needs to be paid to GS management in dementia prevention in elderly population.

Objective:To explore the mechanism of exacerbating chronic graft versus host disease (GVHD) in mice with inflammatory status and enhancing immune injury in mice with PD-1.Method:Bone marrow and spleen cells of DBA/2 mice were injected into BALB/C mice pretreated with chemotherapy regimen (Flu+Bu) for constructing a chronic GVHD model. The animals were assigned into two groups of zymosan (100M SPL+10M BM+Zymosan) and control (100M SPL+10M BM+ PBS). After transplantation, two groups of mice were observed for weight changes, survival status and chronic GVHD manifestations. Target organ tissues were harvested for pathological scoring. Flow cytometry was employed for detecting cell subpopulations and surface co-stimulatory molecules in target organs. PD-1 monoclonal antibody was injected into inflammatory murine model. Mice were observed and target organ cells were harvested for subsets and co-stimulatory factors.Result:In in vivo experiments, zymosan group showed more significant changes of chronic GVHD with higher mortality rate, faster weight loss and more severe symptoms of GVHD. At Week 2 post-transplantation, hematoxylin-eosin stain of target organ tissue was performed for pathology examination. Zymosan group showed more lymphocyte infiltration, more severe inflammation and more significant tissue injury with higher GVHD pathological score. The proportion of M2 in liver/lung of zymosan group was significantly lower than that of control group ( P<0.05) and no significant difference existed in the proportion of M1. In in vivo experiments, M1 ratio of splenic cell spiked markedly in zymosan group as compared to control group while M2 ratio declined greatly. The secretions of IL-4 and IL-10 dropped significantly while co-stimulatory molecules CD80 and CD86 rose obviously. Conclusion:The worsening graft-versus-host disease in inflammatory mice with anti-PD1 treatment is associated with a decline of Treg proportion.

Objective:To investigate the effects of transepithelial photorefractive keratectomy (TransPRK) and femtosecond small incision lenticule extraction (SMILE) on corneal biomechanics measured by the Ocular Response Analyzer in the early postoperative period.Methods:A cohort study was conducted.The right eyes of 56 patients who underwent TransPRK and 52 patients who underwent SMILE in Dalian Medical University Affiliated Dalian Third People's Hospital from November 2020 to June 2021 were continuously included.The postoperative follow-up was 3 months.The central corneal thickness (CCT) and keratometry (Km) were measured 1 month and 3 months after surgery.The corneal-compensated intraocular pressure (IOPcc), corneal resistance factor (CRF), corneal hysteresis (CH), and 19 repeatable mechanical infrared signal waveform parameters measured by the Ocular Response Analyzer were recorded before the surgery, 1 month and 3 months after the surgery, respectively.The measurement indexs at different time points between two groups were compared.This study adhered to the Declaration of Helsinki and the study protocol was approved by the Ethics Committee of Dalian Medical University Affiliated Dalian Third People's Hospital (No.2019-KT-010). Written informed consent was obtained from each patient before surgery.Results:There was no significant difference in CCT, Km, and IOPcc between the two groups at 1 month and 3 months after the surgery (all at P>0.05). In both groups, CRF, CH, p1area, p2area, p1area1, p2area1, w1, w2, w11, w21, h1, h2, h11, h21, dive1, dive2 and mslew1 were decreased, while path1, path2, path11, and aplhf were increased at 1 month after the surgery compared with before surgery, showing statistically significant differences (all at P<0.05). In both groups, CRF, CH, p1area, p2area, p1area1, p2area1, w1, w2, w11, w21, h1, h2, h11, h21, dive1 decreased, while path1, path2, path11, and aplhf were increased at 3 months after the surgery in comparison with before surgery, showing statistically significant differences (all at P<0.05). In SMILE group, the dive2 were decreased at 3 months after the surgery compared with before surgery, and the difference was statistically significant ( P<0.01). At 1 month after the surgery, p1area, p2area, p1area1, p2area1, w1, w2, w11, w21, dive1 and dive2 were higher, while CH, path1, path2, and path11 were smaller in TransPRK group than in SMILE group, showing statistically significant differences between them (all at P<0.05). At 3 months after the surgery, p1area, p2area, p1area1, p2area1, w1, w2, w11, w21, h2, h21, dive1 and dive2 were higher, while path1, path2, and path11 were smaller in TransPRK group than in SMILE group, showing statistically significant differences between them (all at P<0.05). Conclusions:Corneal biomechanics are weakened after both TransPRK and SMILE.In the early postoperative period, the mechanical infrared waveform parameters measured by the Ocular Response Analyzer are better after TransPRK than after SMILE.

Objective:To explore the spatial autocorrelation and macro influencing factors of stroke mortality in Zhejiang Province in 2015-2020 and provide a scientific basis for stroke prevention and control strategy.Methods:The data on stroke death were obtained from Zhejiang Chronic Disease Surveillance System. The spatial distribution of stroke mortality was explored by mapping and spatial autocorrelation analysis. The spatial panel model analyzed the correlation between stroke mortality and socioeconomic and healthcare factors.Results:From 2015 to 2020, the average stroke mortality was 68.38/100 thousand. The standard mortality of stroke was high in the areas of east and low in the west, high in the south and low in the north. Moreover, positive spatial autocorrelation was observed (Moran's I=0.274-0.390, P<0.001). Standard mortality of stroke was negatively associated with per capita gross domestic product (GDP) ( β=-0.370, P<0.001), per capita health expenditure ( β=-0.116, P=0.021), number of beds per thousand population ( β=-0.161, P=0.030). Standard mortality of ischemic stroke was negatively associated with per capita GDP ( β=-0.310, P=0.002) and standard management rate of hypertension ( β=-0.462, P=0.011). Standard mortality of hemorrhagic stroke was negatively associated with per capita GDP ( β=-0.481, P<0.001), per capita health expenditure ( β=-0.184, P=0.001), number of beds per thousand population ( β=-0.288, P=0.001) and standard management rate of hypertension ( β=-0.336, P=0.029). Conclusions:A positive spatial correlation existed between stroke mortality in Zhejiang Province in 2015-2020. We must focus more on preventing and controlling strokes in relatively backward economic areas. Moreover, to reduce the mortality of stroke, increasing the investment of government medical and health funds, optimizing the allocation of medical resources, and improving the standard management rate of hypertension are important measures.

Objective:To analyze the magnetic resonance imaging (MRI) features of diffuse midline gliomas with H3K27M mutation, and to quantitatively analyze the changes of apparent diffusion coefficient (ADC).Methods:The MRI images of 14 cases of diffuse midline gliomas with H3K27M mutation were retrospectively analyzed in the Affiliated Hospital of Qingdao University from April 2017 to November 2019. The location, edge, signal, peritumoral edema and enhancement characteristics of the lesions were observed, and the changes of ADC values were analyzed.Results:The tumors were located in thalamus in four cases, pons in six cases, medulla oblongata in two cases and spinal cord in two cases. In seven cases, the tumor was confined to the midline region, of which six cases had clear boundary, seven cases were located in the midline area, but infiltrated into the non midline area at the same time, and six cases had unclear boundary. Basilar artery entrapment was found in all six patients located in pons. Multiple large cystic changes were found in five cases, multiple small cysts in four cases and no cystic changes in five cases. Cystic changes were found in all seven cases of tumors involving the non midline region, of which six cases were located only in the non midline region, and only two of the seven tumors localized in the midline region had small cysts. Hemorrhage was found in four cases. Five cases showed mild heterogeneous enhancement, six cases showed moderate heterogeneous enhancement, two cases showed obvious enhancement, and one case showed no enhancement. There was no edema around the tumor in nine cases and mild edema in five cases. The average edema index was 1.13. The average ADC value of tumor parenchyma in 12 patients was (7.83±0.88)×10 -4 mm 2/s, which was 15.6% lower than that of the contralateral side [(9.28±0.69)×10 -4 mm 2/s, t=-6.336, P<0.05]. Conclusions:Diffuse midline gliomas with H3K27M mutation have a younger onset age and are more likely to occur in thalamus, brainstem and spinal cord. Most of the tumors have no peritumoral edema or mild peritumoral edema. The tumors confined to the midline region are regular in shape and clear in boundary. The masses involving the non midline area are prone to cystic necrosis. Diffuse midline gliomas with H3K27M mutation in pons are prone to basilar artery entrapment. ADC value can provide a quantitative basis for preoperative tumor grading.

Objective:To analyze the magnetic resonance imaging (MRI) features of epithelioid glioblastoma (eGBM), and to quantitatively analyze the characteristics of apparent diffusion coefficient (ADC) , perfusion-weighted imaging (PWI) and magnetic resonance spectrum (MRS) of eGBM patients.Methods:The MRI results of eight cases of eGBM confirmed by pathology in the Affiliated Hospital of Qingdao University from October 2016 to November 2018 were analyzed retrospectively. The location, edge, signal, peritumoral edema, adjacent meningeal invasion and enhancement of the patients were observed, and the changes of ADC value, relative cerebral blood flow (rCBF), relative cerebral blood volume (rCBV) and the ratio of choline (Cho)/N-acetyl-L-aspartic acid (NAA) were analyzed.Results:Among the eight patients, the main tumors were located in temporal lobe ( n=3), frontal lobe ( n=3) and parietal lobe ( n=2). The boundary of the lesion was clear in six cases and unclear in two cases. The lesions were superficial in five cases and in deep white matter in three cases. Bleeding could be seen in four cases. There were three cases with cystic change and four cases with necrosis, and there was no cystic necrosis only in one case. There was no edema around the lesion in one case, severe edema in five cases and moderate edema in two cases. The adjacent meninge was involved in four cases and the ependyma was involved in one case. Two patients had leptomeningeal metastasis within two months after operation. The average ADC value of tumor parenchyma in eight patients was 7.15×10 -4 mm 2/s, which was 17.6% lower than that of the contralateral side. MRS showed that the ratio of Cho/NAA in the lesions of two patients were 5.27, 0.81. PWI showed that the rCBV in the lesions of two patients was 3.51 ml/100 g and 3.32 ml/100 g, respectively, which was 36% and 29% higher than that of the contralateral side, respectively. And the rCBF of the lesions was 31.5 ml·100 g -1·min -1and 82.1 ml·100 g -1·min -1, respectively, which increased by 49% and 203% respectively compared with the contralateral side. Conclusions:eGBM has the characteristics of superficial location, easy to be cystic, but the wall of the cyst is not smooth and uneven, the boundary of the mass is clear, the adjacent meninges are easy to be involved and the meningeal tail sign appears, and it is easy to be spread by cerebrospinal fluid. ADC value, PWI and MRS can provide some help for preoperative tumor grading.

Objective: To learn the willingness and influencing factors of influenza vaccination among the community managed diabetic patients in Keqiao District, Shaoxing, so as to provide the basis for influenza vaccination promotion. Methods: A self-compiled questionnaire survey was conducted from October to December 2017 among all the managed diabetic patients in Keqiao District. The contents of questionnaire included the basic information of the respondents, awareness of influenza vaccine, vaccination status and vaccination intention. Logistic regression model was used to analyze the influencing factors for the willingness of influenza vaccination. Results: A total of 15 060 questionnaires were sent out and 13 781 valid ones were retrieved, the response rate was 91.51%. There were 3 888 patients with the awareness of influenza vaccine, accounting for 28.21%; 4 259 patients with the willingness to be vaccinated, accounting for 30.90%; 630 previously-vaccinated patients, accounting for 4.57%. The patients who were female (OR=1.157, 95%CI: 1.064-1.258) , were married (OR=1.242, 95%CI:1.107-1.393), were with other chronic diseases (OR=1.199, 95%CI: 1.103-1.303) , believed diabetic patients were more susceptible to influenza (OR=1.251, 95%CI: 1.102-1.419) , believed influenza aggravate diabetes status (OR=1.640, 95%CI: 1.445-1.860) , believed that the vaccination effectively prevent influenza (OR=3.129, 95%CI: 2.866-3.416) , knew about influenza vaccine (OR=1.111, 95%CI: 1.105-1.216) and ever received influenza vaccination (OR=1.316, 95%CI: 1.103-1.570) were more willing to be vaccinated. Conclusions The willingness of influenza vaccination among the community managed diabetic patients in Keqiao District is low. The patients＇gender, married status, other chronic diseases, awareness of influenza vaccine and the history of vaccination can affect the willingness of influenza vaccination.

Objective:To analyze the viral nucleic acid and cytokines in 12 children with 2019-nCoV infection.Methods:Clinical and laboratory data of the children diagnosed with 2019-nCoV infection in Guangzhou Women and Children′s Medical Center from January to April 2020 were retrospectively analyzed. Throat and anal swabs were collected on alternate days for the detection of 2019-nCoV nucleic acid by fluorescence quantitative PCR. Flow cytometry was used to detect serum cytokines including IFN-γ, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-17A, IL-17F, IL-22, TNF-α and TNF-β during the early (both throat and anal swab tests were positive), the intermediate (throat swab test was negative, while anal swab test remained positive), and the convalescence (both throat and anal swab tests were negative) stages of infection.Results:A total of 12 children were enrolled in this study. The male-to-female ratio was 5∶1. The average age was (7.0±4.3) years. There were two asymptomatic, five mild and five common cases. No severe or critical cases were involved. Initially, throat and anal swab nucleic acid tests were simultaneously positive in nine children newly diagnosed in our hospital and the median time of viral shedding in throat swab was longer than that in throat swab [32 (4.5, 45.0) d vs 3 (2, 9) d, Z=11.0, P=0.010]. The median difference of viral shedding time between anal swab and pharyngeal swab was 25.5 (1.5, 42.8) d. The overall levels of serum cytokines IL-17A, IL -4 and IL-5 in different stages of the disease (early, intermediate and convalescence stage) were statistically different ( Z or F, P values were 8.33, 0.016; 5.36, 0.010 and 6.56, 0.004, respectively), and a significant increase was observed in the intermediate stage of infection. IL-17F, IL-2 and IL-22 were all increased during the infection, but there was no significant statistical difference among the three stages ( P>0.05). Conclusions:It was noted that intestinal viral shedding needed a longer time. Although the infectivity has not been determined, higher requirements have been put forward for disease prevention and control. Cytokines secreted by Th2 and Th17 cells were involved in the immune response in children with non-severe 2019-nCoV infection. Monitoring viral shedding and cytokine changes in pediatric patients would be conducive to disease assessment.
