AIM:To investigate the relationship between autophagy and calcification in vascular smooth muscle cells ( VSMCs) after platelet-derived growth factor (PDGF)-BB stimulation.METHODS:Cultured VSMCs were stimulated with PDGF-BB for different time, the expression of vascular calcification-related proteins and autophagy-related proteins were detected by Western blot .The interaction be-tween Beclin1 and PI3KC3 was detected by co-immunoprecipitation.RESULTS: The expression of BMP2 and ALP showed a trend from decline to rise.ALP slumped at 12 h, and BMP2 slumped at 6 h.Moreover, the expression of Beclin-1 showed a trend from rise
to decline, and peaked at 12 h.The conversion of LC3-ⅠtoⅡincreased in a time-dependent manner , and peaked at 24 h.The ex-pression of BMP2 and ALP was increased in VSMCs incubated with PDGF-BB and autophagy inhibitor 3-MA, compared with PDGF-BB-stimulated VSMCs.Furthermore, the interaction between Beclin1 and PI3KC3 was enhanced at 6 h after PDGF-BB stimulated, peaked at 12 h, and kept in high level at 24 h.Moreover, the phosphorylation level of Beclin 1 was enhanced by PDGF-BB stimulation, and peaked at 6 h.CONCLUSION:Our findings demonstrate that PDGF-BB-induced autophagy inhibits VSMC calcification by en-hancing Beclin1 phosphorylation and interaction between Beclin 1 and PI3KC3.

Objective To evaluate the relationship between the cytokine levels in the serum and cerebrospinal fluid and the brain injury in preterm infants. Methods From August of 2012 to August of 2013,51 preterm infants were included and 46 infants were survived. All of them were born at the Maternal and Child Hospital of Hubei Pro-vince,with GA≤32 weeks and high risk factors of intrauterine infection and suffering from early onset sepsis. Ac-cording to the screening findings of cerebral ultrasound and/or MRI,the infants were divided into normal group(n=28) and abnormal groups(n=18) with intracranial hemorrhage or white matter damage. The levels of interleukin(IL)-6,IL-1β and tumor necrosis factor-α( TNF-α) in the serum within 12 hours after birth and in cerebrospinal fluid within 72 hours after birth were investigated. The differences in cytokines between two groups were compared with t-test and Chi-square test,and high risk factors of brain injury were analyzed by Logistic regression models. Results The ab-normal group had higher incidence of clinical maternal chorioamnionitis[44. 44%(8/18 cases) vs 14. 29%(4/28 ca-ses),χ2=5.168,P=0.038] and higher white blood cell count[(11.51±9.03)×109/L vs(6.95±5.64)×109/L,t=-2. 107,P=0. 041]. In the abnormal group,the levels of serum IL-6 [(44. 83±16. 31) ng/L],and IL-6,IL-1βand TNF-αin cerebrospinal fluid [(51. 85±15. 65) ng/L,(11. 95±2. 58) ng/L and(193. 11±67. 25) ng/L] were higher than those in the normal group[(36.83±8.76) ng/L,(42.56±12.89) ng/L,(10.26±2.91) ng/L and(160.56± 29. 02) ng/L,respectively] with the statistical difference(t=-2. 687,-2. 250,0. 269,-2. 243,P=0. 010,0. 029,0. 044, 0. 030). Maternal chorioamnionitis,higher serum TNF-αand cerebrospinal fluid IL-6 were high risk factors for brain in-jury(P=0. 014,0. 031,0. 047). Conclusion Increased systemic and cerebrospinal fluid cytokine levels are possibly re-lated to the preterm brain injury when intrauterine infection occurred.

Objective: To analysis gender disparities in epidemiological trend of HIV/AIDS disease burden among Chinese population aged 10-24 years from 1990 to 2019. Methods: The Global Burden of Disease Study (GBD 2019) results tool was used to extract the number of deaths, mortality rate, disability adjusted life years (DALY), DALY rate, years of life lost (YLL), YLL rate, years lived with disability (YLD) and YLD rate to comprehensively analyze the change range of HIV/AIDS disease burden in the Chinese population aged 10-24 years from 1990 to 2019. Results: In 2019, the number of deaths, mortality rate, DALY, DALY rate, YLL, YLL rate, YLD and YLD rate of Chinese population aged 10-24 years due to HIV/AIDS were 847, 0.37 per 100 000 , 62 621 person years, 27.51 per 100 000, 58 036 person years, 25.49 per 100 000, 4 584 person years, 2.01 per 100 000 respectively, with the increase of 401.18%, 691.49%, 370.48%, 648.26%, 409.53%, 710.33%, 138.87% and 279.25% , compared with the data in 1990. In term of gender, the number of deaths, mortality rate, DALY, and DALY rate of Chinese male population aged 10-14, 15-19 and 20-24 years due to HIV/AIDS in 2019 were higher than those of female, and the growth rate (compared with 1990) was also higher than that of female. In term of the age group, the increase in people aged 10-14 years was higher than that of people aged 20-24 years. From 1990 to 2019, with the increase of year and age, gender disparity between mortality and DALY rate widened. Conclusion Compared with data in 1990, the risk of HIV/AIDS infection in 2019 among Chinese population aged 10-24 years continued to increase, especially among young people of 10-14 years. Gender disparity is exacerbating.

Purpose To investigate the expression of TRPS1 in synovial sarcoma(SS)and its significance.Methods Twenty-one cases of synovial sarcoma diagnosed by SS1 8(18q11)(SYT)fluorescence in situ hybridization(FISH)or SS18-SSX immunohistochemistry were collected.The expression of TRPS1 was detected by immunohistochemistry EnVision two-step staining,and the relevant literature was reviewed.Results There were 21 cases of synovial sarcoma,including 9 females and 12 males,aged 17-79 years,with a median age of 50 years and an average age of 47.1 years.The tumors occurred in the lung(3 cases),legs(3 cases),kidney(3 cases),feet(2 cases),psoas major muscle(2 cases),rectum(1 case),tho-racic cavity(1 case),ankle canal(1 case),inguinal area(1 case),knee(1 case),palm(1 case),nasal cavity(1 case),and forearm(1 case).The maximum diameter of the tumor was 1.2-13 cm.Grossly,the tumor section was grayish-white,grayish-yellowish solid,and the lesion with hemorrhage was dark red.Microscopically,there were monophasic fibrous SS(16/21,76.2％),poorly differential SS(small cell)(3/21,14.3％),and biphasic SS(2/21,9.5％).Immunophenotypi-cally,tumor cells expressed SS18-SSX(18/18,100％),TLE1(12/12,100％),BCL2(18/18,100％),partially expressed EMA(10/16,62.5％),CK(12/18,66.7％),CD99(4/10,40.0％),SMA(3/16,18.6％),S-100(3/19,15.8％),and desmin(0/21).The proliferation index of Ki67 ranged from 3％-80％,with an average of 39.9％.FISH test showed that all 11 cases were positive for SS18(18q11)split-ting.All 21 cases of SS expressed TRPS1 to varying degrees and intensities(21/21,100％),of which 19 cases(19/21,90.5％)had a positive range of＞50％.There were 19 cases(19/21,90.5％)with a positive intensity of 2+or above.All the 21 patients underwent surgical resection of the tumor,and 20 patients received follow-up visits.3 patients treated with postop-erative combination of radiotherapy and chemotherapy,18 pa-tients treated with postoperative chemotherapy,and 7 patients showed different degrees of recurrence or metastasis,and 9 pa-tients who received follow-up visits died(45％,9/20).Con-clusion Although TRPS1 is regarded as a highly sensitive and specific marker of breast tumor origin,it is also highly expressed in synovial sarcoma,and it is necessary to be vigilant at its pit-falls in the pathological diagnosis.

Objective To analyse the hot topics(CKD)frontiers,and of blood pressure monitoring in research of chronic kidney disease(CKD)at home and abroad,and provide references for future research in this field.Methods Articles on blood pressure monitoring in published in Web of Science,China Knowledge Network Infrastructure(CNKI),Wanfang(Wanfang Data)and China Science and Technology Journal Database(VIP)from 2011 to 2022 were searched,and CiteSpace 5.8.R3 visual analysis software was employed to analyse the number of articles involved,country,institution,keyword co-occurrence.The analysis was performed on the number of published papers,countries,institutions,keyword co-occurrence atlas,high frequency subject terms,keyword emergence and emergence of literatures.Results ① A total of 504 articles in English and 72 articles in Chinese were extracted from the literature search.Annual distribution of the number of articles generally showed a continuous upward trend,in which 2 peaks of articles were formed in 2016 and 2018;the main country of issuance was the United States,and the main institution of issuance was the Aristotle University of Thessaloniki,Greece;② In the analysis of keyword co-occurrence,8 high-frequency keywords with a word frequency greater than or equal to 30 were identified.It indicated that the research hotspots mainly focused on the classification of hypertension,the characteristics of blood pressure circadian rhythm,the management of cardiovascular disease and the prediction of death and prognosis in the blood pressure monitoring of CKD;③ Further testing of the emergent terms and emergent literatures yielded 23 strongest emergent terms and 11 emergent literatures,which went through three stages of development,namely,early,intermediate and latest.It was found that the research gradually shifted from the application of blood pressure monitoring in the assessment and diagnosis of kidney disease to the treatment,management and prognostic assessment of hypertension in CKD Conclusion The importance of blood pressure monitoring in the management of hypertension in CKD has received increasing attention from researchers,and future researches should focus on using different blood pressure monitoring schemes to enhance the assessment of cardiovascular risks and the individualised management of hypertension.

Epilepsy patients are prone to obesity and metabolic syndrome(MetS),which is a higher risk than the general population.Nonalcoholic fatty liver disease(NAFLD)is a manifestation of a metabolic syndrome,characterized by hepatic steatosis,which can be exacerbated to some extent in patients with epilepsy.Sodium valproate(VPA),a commonly used clinical antiepileptic drug,leads to triglyceride accumulation in liver cells and induces a risk of NAFLD.In adults with epilepsy combined with NAFLD,treatment with VPA can make the liver,which is already affected by steatosis,more sensitive to VPA-induced liver injury and affect VPA drug metabolism.Both VPA and NAFLD induce hepatic steatosis,and can exacerbate each other's induced hepatic steatosis synergistically during epilepsy treatment.In this paper,we reviewed the progress of clinical studies on the use of VPA in adult patients with epilepsy combined with NAFLD to provide references for effective treatment and future studies of VPA.

Objective:To analyze the mediating effect of psychological capital (PsyCap) between occupational stress and suicidal ideation.Methods:In September 2017, stratified-cluster sampling method was adopted to select employees of an electronic manufacturing service industry as respondents for a questionnaire survey in Jiangsu province. The demographic characteristics of employees were collected. A total of 2 465 employees were investigated, and 2 216 valid questionnaires were collected. The level of occupational stress and PsyCap was assessed by the Effort-Reward Imbalance Scale(ERI)and PsyCap Questionnaire.Results:The age of 2 216 employees was (28.70±5.26) years old, including 1 230 males (55.5%). The scores of occupational stress on effort, reward and over-commitment were (3.08±0.63), (3.73±0.60) and (2.51±0.68), respectively. The average ERI index (ratio of effort to return) was (0.88±0.39). The total score of PsyCap was (86.62±15.23). The detection rate of suicidal ideation within two weeks was 13.9% (309/2 216). The average score of effort and over-commitment and the ERI index were positively correlated with the number of suicidal ideation detected within two weeks, with correlation coefficients about 0.081, 0.141 and 0.164, respectively. The average score of reward and total score of PsyCap were negatively correlated with the number of suicidal ideation detected within two weeks, with correlation coefficients about -0.206 and -0.228, respectively. The mediating effect results showed that PsyCap had mediating effect on the effort, reward, over-commitment and suicidal ideation of occupational stress respectively, with mediating effect values of -0.087 (95% CI: -0.018,-0.019), -0.299 (95% CI: -0.428,-0.200) and 0.096 (95% CI: 0.0394, -0.170). The mediating effect percentages were 9.43%, 17.92%, and 9.54%, respectively. Conclusion:PsyCap has a mediating effect between effort, reward, over-commitment of occupational stress and suicidal ideation.

Objective:To evaluate the reliability and validity of the information needs assessment scales for breast cancer patients, so as to recommend an appropriate information needs assessment scale for breast cancer patients.Methods:Researches on the information needs assessment tools for breast cancer patients were retrieved by computer in PubMed, Embase, PsycINFO, EBSCOhost, WOS Core Collection, China National Knowledge Infrastructure (CNKI) , WanFang Data, and China Biomedical Literature Database. The inclusion criteria included that the research content was the breast cancer patient information needs scale/tumor patient information needs scale and the original research sample included breast cancer patients, and outcome indicators included reliability and validity. Exclusion criteria included assessment of information needs of family members/caregivers of breast cancer patients, assessment of unmet information needs, languages other than Chinese and English, comments, reviews, qualitative studies, systematic reviews, and Meta-analyses. The measurement characteristics of the scale were evaluated using the measurement characteristics evaluation criteria in the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) evaluation manual.Results:A total of 1 293 articles were retrieved, and 13 articles were finally included. The 13 scales had no hypothesis test of construct validity, cross-cultural validity, criterion validity and reactivity index. 11 of the scales were recommended as Grade B, and 2 were recommended as Grade C. Combined with the methodological quality evaluation results and measurement characteristics evaluation results, and the consistency between the research and development population and the user population, the Psychological Needs of Cancer Patient Scale and the Comprehensive Needs Assessment Tool in cancer (CNAT) are the optimal scales.Conclusions:There are currently no recommended scales according to the COSMIN guidelines. Considering the methodological quality, the evaluation results of measurement characteristics, and the consistency between the research and development population and the user population, the Psychological Needs of Cancer Patient Scale and the CNAT are the optimal scales.

Objective:To validate the performance of cardiovascular risk prediction models based on the Sweden National Diabetes Register (NDR) and Diabetes Lifetime-perspective prediction (DIAL) model for assessing risks of 5-year and 10-year cardiovascular disease (CVD) among Chinese patients with type 2 diabetes.Methods:Based on the Chinese Electronic Health Records Research in Yinzhou study, 83 503 patients with type 2 diabetes aged 30-75 years without a history of CVD at baseline were included from January 1, 2010 to December 31, 2020. Recalibrated NDR model was used to estimate 5-year risk, while the recalibrated DIAL model was used to predict 5-year and 10-year risks. The competing events adjusted Kaplan-Meier analysis was used to obtain the observed cardiovascular events. Discrimination C statistics evaluated model accuracy, calibration χ2 value, and calibration plots. Results:Through a median follow-up of 7.0 years, 7 326 cardiovascular events, and 2 937 non-vascular deaths were identified among a total of 83 503 subjects. The recalibrated NDR model overestimated 5-year risk by 39.4% in men and 8.6% in women, whereas the overestimation for the recalibrated DIAL model was 14.6% in men and 50.1% in women. The DIAL model had a better discriminative ability ( C-statistic=0.681, 95% CI: 0.672-0.690) than NDR model ( C-statistic=0.667, 95% CI: 0.657-0.677) in 5-year risk prediction for men, and the models had a similar ability for women ( C-statistic=0.699, 95% CI: 0.690-0.708 for NDR and C-statistic=0.698, 95% CI: 0.689-0.706 for DIAL). The prediction accuracy of the DIAL model was improved in the 10-year risk, with the underestimation being 1.6% for men and the overestimation being 12.8% for women. Conclusions:Both recalibrated NDR and DIAL models overestimated 5-year cardiovascular risk in Chinese patients with type 2 diabetes, while the higher overestimation was shown using the DIAL model. However, the improvement was found in predicting 10-year CVD risk using the DIAL model, which suggested the value of lifetime risk prediction and indicated the need for research on the lifetime risk prediction model for cardiovascular risk assessment in Chinese patients with type 2 diabetes.
